Two methods for determining the system temperature are described here: the hot/cold-method and the derivation from the radiometer equation using measurement data from a source with a known brightness temperature, in this case, S7. Both methods deliver different results, depending on the measurements and assumptions on which they are based. The results show that the data basis and uncertainties should always be considered when analysing the observational data to be able to evaluate the results correctly. Overall, the telescope is quite suitable for educational observations, especially of the 21-cm line of neutral hydrogen. Furthermore, instructions have been created for the various tasks so that the results are reproducible and comprehensible. The entire process is made transparent, from planning the observations and setting up the telescope to measuring and analysing the data. In addition, basic concepts of radio astronomy are described in theory to provide valuable background knowledge. On this basis, the use of the telescope enables students and amateur astronomers to understand and apply the basic principles of radio astronomy and to plan and carry out their own observations.}, language = {en} } @masterthesis{Melnic2025, type = {Bachelor Thesis}, author = {Melnic, Snejana}, title = {Drawbacks of law enforcement in the Euregio Rhine-Waal: the case of work migrants' exploitation in the border region}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {This thesis examines the challenges of enforcing labor protection for migrant workers in the Euregio Rhine-Waal, a dynamic cross-border region extended across Germany and the Netherlands. The study addresses three core research questions: the specific difficulties faced by migrant workers in accessing adequate housing, fair labor rights, and social security; the role of EU directives and Member State discretion in shaping labor protections; and the enforcement gaps impacting workers' rights and well-being. A qualitative approach was applied, focusing on the analysis of EU regulations, national policies, and case studies to identify systemic barriers and regulatory inconsistencies. The findings reveal significant disparities in housing standards, labor conditions, and access to social security, driven by divergent interpretations of EU directives by Germany and the Netherlands. Additionally, the lack of coordinated cross-border enforcement amplifies these issues, leaving many migrant workers vulnerable to exploitation. The study concludes that addressing these challenges requires enhanced cross-border cooperation, greater regulatory alignment, and targeted policy reforms to bridge the enforcement gaps. These recommendations aim to uphold the EU's core value of free movement while ensuring social equity for migrant workers. This research contributes to the broader discourse on labor mobility by highlighting the interplay between legal frameworks and social justice in cross-border regions.}, language = {en} } @misc{OPUS4-2151, title = {06/2025 Zweite {\"A}nderungssatzung zur Pr{\"u}fungsordnung des Bachelorstudiengangs Nachhaltiger Tourismus der Fakult{\"a}t Gesellschaft und {\"O}konomie vom 11.11.2024}, volume = {2025}, number = {06}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21515}, pages = {5}, language = {de} } @misc{OPUS4-2150, title = {05/2025 Zweite {\"A}nderungssatzung zur Pr{\"u}fungsordnung des Bachelorstudiengangs International Taxation and Law der Fakult{\"a}t Gesellschaft und {\"O}konomie vom 27.11.2024}, volume = {2025}, number = {05}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21509}, pages = {6}, language = {de} } @misc{OPUS4-2149, title = {04/2025 Dritte {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Bachelorstudiengang International Business and Management der Fakult{\"a}t Gesellschaft und {\"O}konomie vom 11.11.2024}, volume = {2025}, number = {04}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21494}, pages = {7}, language = {de} } @misc{OPUS4-2148, title = {03/2025 Zweite {\"A}nderungssatzung zur Pr{\"u}fungsordnung des Bachelorstudiengangs International Relations der Fakult{\"a}t Gesellschaft und {\"O}konomie vom 11.01.2024}, volume = {2025}, number = {03}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21480}, pages = {5}, language = {de} } @masterthesis{Klose2025, type = {Bachelor Thesis}, author = {Klose, Hanna Lara Sophie}, title = {Development of an Online Presence for Northstar Roleplay}, school = {Hochschule Rhein-Waal}, year = {2025}, abstract = {In this thesis, the multiplayer modification RedM and the competitors on it, have been explored in order to establish an online presence that distinguishes Northstar Roleplay from other RedM servers.

The experiment monitored daily feed intake and health parameters from birth to at least six weeks of age for heifer calves from two groups and from birth to three weeks of age from further two groups, and from birth to four weeks for bull calves, alongside weekly assessments of growth progression. T-test results did not reveal significant differences among the examined parameters when various groups were compared head-to-head. However, observable differences were noted, specifically in the amount of feed intake during the first few weeks, where calves fed dry TMR showed increased feed intake. Additionally, calves fed dry TMR exhibited less susceptibility to digestive disorders and a subsequent need for clinical treatment. Regarding sustainability, dry TMR showed advantages in ease of handling and storage, reducing time investment and feed waste. Wet TMR showed advantages in palatability and feed intake nearing the 5-week mark of the calves' age. However, wet TMR posed challenges, in terms of time required for its preparation.

Most existing beehive monitoring systems lack machine learning (ML) capabilities for anomaly detection and rely on threshold-based methods or expensive, complex designs. This thesis utilized the DigiBee prototype, a cost- effective monitoring system, to develop an ML-based anomaly detection model using Isolation Forest. Data on temperature, humidity, sound, vibration, and weight from four active beehives was collected between May 1, 2024, and July 25, 2024, alongside environmental data—temperature, relative humidity, and precipitation—from nearby meteorological stations. Exploratory data analysis revealed several limitations: uniform outputs from vibration sensors, calibration errors in weight sensors, and multiple gaps during the data collection period. Correlation analysis indicated a limited influence of external weather variables on internal beehive conditions, while internal sensor parameters displayed stronger correlations with each other. Five models were developed, using either beehive data alone or a combination of beehive and weather data. Results showed that beehive-specific models achieved higher accuracy in detecting localized anomalies, whereas models combining data from multiple beehives generalized better but underrepresented hive-specific issues. Models incorporating weather parameters, especially precipitation, introduced noise and unnecessary dimensions, which, when excluded, improved the model's prediction by focusing on hive-specific patterns and ensuring anomaly detection remained contextually relevant.}, language = {en} } @masterthesis{Biffo2025, type = {Bachelor Thesis}, author = {Biffo, Fabio}, title = {Laser Modification of Thin Polymer Coatings}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21410}, school = {Hochschule Rhein-Waal}, pages = {71}, year = {2025}, abstract = {Traditional manufacturing techniques are well-established for processing polyimides, such as Kapton®.

It has latitude 52,362324 and longitude 7,269548 with temperature from 10°C to 25 in summer and temperature ranges from -1°C to 7°C in winter. In this context, two gardens with different climatic conditions, represented by the gardeners DE from Germany and ES from Spain, were considered. The latter is located at latitude 41,39467 and longitude 2,157998, with summer temperatures ranging from 20 to 30°C and winter temperatures from 10 to 15°C. Greenhouse vegetable production requires significant energy inputs for heating and lighting, particularly during the winter months. However, the environmental implications of using renewable energy sources like hydroelectricity and the effects of other production strategies on the environment have not been adequately investigated. To address this knowledge gap, a life cycle assessment (LCA) of greenhouse tomato production for year-round production in 2022 has been conducted, including processes from seedling planting in a pre-build greenhouse structure to distribution at two locations: the ES Gardner in Spain and the DE Gardner in Germany. The study used the OpenLCA software and followed the ReCipe 2016 Mid-Point (H) impact assessment methodology. Our analysis revealed that, across the two main production seasons, the highest global warming potential (GW) was observed during year-round production in Spain. The following aspects were discovered to have a significant influence on the environmental impact: Packaging material, transportation, heating systems, electricity, land usage, and irrigation methods. Overall, it was determined that year-round production in Germany had the least detrimental environmental impact among the examined production types. The use of packaging material, electricity for heating the greenhouse and transportation was the primary contributor to most of the impact categories. Conversely, the application of fertilizers and manures during extended seasonal and year-round production had a lower environmental impact.}, language = {en} } @masterthesis{Ratnayake, type = {Bachelor Thesis}, author = {Ratnayake, Hasiru}, title = {A Systematic Review of Rapamycin- Mediated Fetal Hemoglobin Induction via the mTOR Pathway}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-21155}, school = {Hochschule Rhein-Waal}, pages = {55}, abstract = {mTOR inhibitor rapamycin has been observed to induce fetal hemoglobin in patients of β-hemoglobinopathies, a group of disorders in which mutations in the gene responsible β-globin chains results in reduced or malformed RBC production, leading to anemia. The induction of fetal hemoglobin bypasses these mutations, as they are found on the gene responsible for adult hemoglobin. Following birth, the fetal hemoglobin gene is silenced, and the adult gene is activated through a process known as the hemoglobin switch. Rapamycin treatment reverses this hemoglobin switch but the mechanism by which it does so is currently unknown. Rapamycin functions through its inhibition of mTORC1, a protein complex responsible for nutrient- and growth factor-dependent cell growth and proliferation. This literature review seeks to collate existing information on the mTORC1 signalling pathway and the hemoglobin switch, allowing for a specific mechanism by which rapamycin induces fetal hemoglobin through its inhibition of mTORC1 to be hypothesized. Following the literature search, 55 studies on the mTORC1 pathway and 31 studies on the hemoglobin switch were summarized. Using the information gained from this, three hypotheses were put forward for the possible induction mechanism, out of which the primary hypothesis is based on the hemoglobin switching factor KLF1. This was based on the observation that the knockdown of Raptor, a crucial component of mTORC1, in mice caused a decreased expression of KLF1. As KLF1 is an essential component of the hemoglobin switch, this provides a direct link between the inhibition of mTORC1 and the reversal of the hemoglobin switch. Additionally, the efficiency of rapamycin in comparison to other methods of fetal hemoglobin was discussed, including newer generations of mTOR inhibitors developed using rapamycin as a foundation.

Das methodische Vorgehen orientierte sich an den Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Die Suche erfolgte auf den Datenbanken Web of Science, ScienceDirect, PubPsych, PubMed und PsycArticles. Zur Bewertung der methodischen Qualit{\"a}t und Bewertung des Verzerrungspotenzials der eingeschlossenen Studien, wurden die Critical Appraisal Checklisten des Joanna Briggs Instituts (JBI) verwendet. Die Ergebnisse der Studien wurden anhand zweier Evidenztabellen nach Studiendesign und Studienergebnissen synthetisiert und narrativ beschrieben. Ergebnisse: Insgesamt erf{\"u}llten 19 von 1.676 gepr{\"u}ften Studien die Einschlusskriterien. Die Studien untersuchten unterschiedliche Copingstrategien und -stile, wie Verhaltensweisen des umweltfreundlichen Handelns sowie problem-, emotions- und bedeutungsorientierte Bew{\"a}ltigungsstrategien. Verschiedene Faktoren wurden ber{\"u}cksichtigt, darunter emotionale Reaktionen, psychologische, soziale und kognitive Aspekte sowie soziodemografische Eigenschaften. Zun{\"a}chst wurde untersucht, wie Copingstrategien in Verbindung mit den einbezogenen Faktoren stehen. Darauf aufbauend wurde analysiert, wie diese Copingstrategien die mentale Gesundheit beeinflussen und ob die Faktoren im Kontext des Klimawandels als Schutz- oder Risikofaktoren wirken. Beispielsweise zeigten leichte Auspr{\"a}gungen der Angst vor dem Klimawandel sowohl aktivierende Effekte, in Form von umweltfreundlichen Verhaltensweisen, als auch die Neigung zu mentalen Beeintr{\"a}chtigungen, bei starker Auspr{\"a}gung. Sorgen zeigten im Studienvergleich gemischte Auswirkungen, indem sie teilweise problemorientiertes Coping beg{\"u}nstigten, teilweise jedoch auch belastend wirkten. Wut zeigte vorwiegend aktivierende Effekte und weniger Beeintr{\"a}chtigungen f{\"u}r die mentale Gesundheit. Naturverbundenheit, Geschlecht und Alter standen oftmals mit problemorientiertem Coping in Verbindung, jedoch gleichzeitig mit einer erh{\"o}hten Anf{\"a}lligkeit f{\"u}r mentale Beeintr{\"a}chtigung. Daneben wurden zwei Studien identifiziert, die unterschiedliche Maßnahmen zur Reduktion der mentalen Belastungen durch den Klimawandel evaluierten und bei relevanten Parametern der mentalen Gesundheit positive Ergebnisse erzielten. Schlussfolgerung: Es besteht verst{\"a}rkter Forschungsbedarf, um die mentalen Auswirkungen im Kontext der Wahrnehmung des Klimawandels besser zu verstehen und wirksame Maßnahmen zur F{\"o}rderung der mentalen Gesundheit zu entwickeln. Ein einheitliches Verst{\"a}ndnis der untersuchten Konstrukte ist dabei entscheidend, um eine Vergleichbarkeit zwischen den Studien zu gew{\"a}hrleisten und gesicherte Erkenntnisse zu gewinnen. Damit kann die Entwicklung zielgerichteter Maßnahmen und die F{\"o}rderung von pers{\"o}nlichen Ressourcen sowie adaptives Coping im Zusammenhang mit der Klimakrise unterst{\"u}tzt werden.}, language = {de} } @misc{OPUS4-2097, title = {16/2024 Vierzehnte {\"A}nderungssatzung zur Beitragsordnung der Studierendenschaft der Hochschule Rhein-Waal vom 30.10.2024}, volume = {2024}, number = {16}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20975}, pages = {3}, language = {de} } @masterthesis{Sturza, type = {Bachelor Thesis}, author = {Sturza, Loredana}, title = {Selection of Global Standardization Samples for Optical Emission Spectrometry from Practical and Materials Science Perspectives}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20939}, school = {Hochschule Rhein-Waal}, abstract = {The focus of this thesis is to address the task of alloy selection for Optical Emission Spectrometry (OES) applications. The main goal is to develop standardised samples for SPECTRO OES devices that can be utilised during routine analysis in automatic processes. The selection criteria include machinability, signal performance, and homogeneity. To achieve these goals, a set of practical tests were carried out. The initial research involves using the existing SPECTRO sample library to identify suitable alloys for standardised production in large batches. In the end, a database is suggested with existing alloys as possible candidates for future production. The chosen alloy must generate signals within specified wavelength ranges and exhibit machinability for post-analysis processing. The thesis introduces a unique approach to assessing machinability using chip analysis, emphasising the role of chip characteristics in understanding the material's suitability for machining. The study found that the E/3 sample, especially among samples with zirconium, demonstrated exceptional machinability. Moreover, the research delves into the importance of power consumption measurements during milling as an informative parameter for machining requirements. The study examines the chemical composition necessary to produce consistent and robust signals across the spectrum, with a particular focus on elements like zirconium, nickel, iron, copper, titanium, and manganese, but also phase diagrams to understand the homogeneity of aluminium alloying elements. Sample 518X905 is highlighted for its role in enhancing emission lines. In conclusion, the thesis proposes an alloy composition that blends aluminium with various alloying elements to meet specific research requirements. Copper, iron, zinc, silicon, nickel, zirconium, chromium, and vanadium provide flexibility for crafting tailored samples. Existing primary alloying elements, including those with copper, zinc, and silicon, can be considered. However, zirconium with a concentration of 0.6\% to 1\% is pivotal in the proposed alloy recipe.}, language = {en} } @masterthesis{Weinrich, type = {Bachelor Thesis}, author = {Weinrich, Johannes}, title = {Effects of the Agricultural Minimum Wage Increase on the Special Crop Sector in Germany}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20925}, school = {Hochschule Rhein-Waal}, pages = {58}, abstract = {This thesis explores the impact of rising labor costs, driven by minimum wage increases, on Germany's specialty crop sector, with a focus on strawberries and asparagus.

Through analysis of data, this work finds a notable reduction in the number of farms and cultivated areas for both strawberries and asparagus, alongside fluctuations in yield and production volumes. The results suggest that while mechanization offers some relief from rising labor costs, its adoption is limited by high initial investment requirements, technical complexity, and the need for crop-specific solutions.

This study aimed to develop a robust machine learning model for classifying schizophrenia patients using neurophysiological markers derived from Electroencephalography (EEG) data. The work explored multiple machine-learning architectures, including traditional Support Vector Machines (SVM) and deep learning models such as Long Short-Term Memory (LSTM) and CNN-LSTM hybrids. EEG data was collected from schizophrenia patients and healthy controls, with preprocessing conducted using the Brain Imaging Data Structure (BIDS) framework to ensure consistency and standardization. Given the varying quality and structure of the EEG recordings—such as missing channels and differing recording lengths—the study employed several preprocessing techniques, including channel interpolation, zero-padding, and limiting data to the first three minutes of resting-state recordings for standardization. Data imbalance was addressed through the application of the Synthetic Minority Over-sampling Technique (SMOTE) to ensure balanced representation of both schizophrenia and control groups during model training. The findings showed that the SVM model reached an accuracy of 88.8\% in patient classification, whereas the LSTM model, after addressing data imbalances through SMOTE, achieved an improved classification accuracy of 99.3\%. However, challenges arose when attempting to predict schizophrenia severity levels using MMN task data and a CNN-LSTM hybrid model. Despite efforts to standardize the number of epochs across subjects, the model achieved a more modest accuracy of 66.7\%. This lower accuracy was largely attributed to the limited and unbalanced dataset, as some subjects had fewer than the target number of epochs. Further challenges included BIDS conversion issues due to discrepancies in file naming conventions between .sdt and .set files, which required considerable time to resolve. The successful creation of a tailored BIDS conversion script ensured the data could be standardized and used effectively for analysis. In conclusion, while the classification models achieved high accuracy, particularly the LSTM-based approach, predicting schizophrenia severity levels remains a challenge due to the limitations of the available dataset. Future research will focus on gathering larger and more balanced datasets, refining preprocessing methods, and optimizing model architectures to improve prediction accuracy. Ultimately, the goal is to apply these models in clinical settings to facilitate early diagnosis and intervention, providing timely medical care to schizophrenia patients before their symptoms worsen.}, language = {en} } @masterthesis{Ruesel, type = {Bachelor Thesis}, author = {R{\"u}sel, Henri}, title = {Prototypische Entwicklung eines Geoinformationssystems zur Koordination von Flugger{\"a}ten der Polizei Nordrhein-Westfalen w{\"a}hrend der Fußball-Europameisterschaft 2024}, school = {Hochschule Rhein-Waal}, abstract = {This bachelor thesis explores the prototypical development of a Geographic Information Sys-tem (GIS) for coordinating police aerial devices in North Rhine-Westphalia during the UEFA Euro 2024.

Im Rahmen der Vorbildfunktion wird erwartet, dass Berufst{\"a}tige der Ge-sundheitsprofessionen eine hohe Gesundheitskompetenz aufweisen und sich entsprechend gesund-heitsf{\"o}rderlich verhalten. In einer zunehmend belastenden Arbeitswelt sind individuelle Ressourcen entscheidend f{\"u}r die Gesundheit und das Stresserleben des Gesundheitsfachpersonals. In der vorlie-genden Arbeit soll untersucht werden, inwieweit die Faktoren „gesundheitsbezogenes Verhalten" und „Stresserleben" durch das Level der Gesundheitskompetenz in Gesundheitsfachberufen beeinflusst wird. Da das berufliche Belastungsspektrum von Physiotherapeut:innen und Pflegekr{\"a}ften teilweise vergleichbar ist, wird in dieser Masterarbeit im Sinne einer quasi-explorativen Querschnittsstudie ein Vergleich zwischen diesen Gesundheitsfachberufen gezogen. Methodik: Zur Erhebung der Daten wurde vom 12.02.2024 bis 11.03.2024 eine quantitative Online-Umfrage durchgef{\"u}hrt. Dazu wurden aktuell t{\"a}tige und examinierte Pflegekr{\"a}fte und Physiotherapeut:innen ab 18 Jahren mittels Schnee-ballverfahren rekrutiert. Zur Erhebung der Gesundheitskompetenz wurde der Fragebogen HLS19-Q12-DE verwendet, sowie einzelne Skalen des COPSOQ und dem SOC-L9 zur Erfassung des Stres-serlebens und des Koh{\"a}renzgef{\"u}hls. Dar{\"u}ber hinaus wurden einzelne Items aus der GEDA-Studie 2019 des Robert Koch- Instituts zur Erfassung des gesundheitsbezogenen Verhaltens einbezogen. Zur Datenauswertung wurden uni- und bivariate deskriptive Analysen vorgenommen, aber keine R{\"u}ck-schl{\"u}sse auf die Grundgesamtheit gezogen. Ergebnisse: Im Rahmen der Fragebogenerhebung konnte eine Stichprobengr{\"o}ße von n = 124 erzielt werden, welche sich in 62,1 \% Physiotherapeut:innen und 37,9 \% Pflegekr{\"a}fte teilt. Es zeigt sich eine durchschnittlich problematische Gesundheitskompetenz der Stichprobe und dichotomisiert weisen 68,6 \% der Befragten eine geringe Gesundheitskompetenz auf, wobei mehr Pflegekr{\"a}fte eine hohe Gesundheitskompetenz aufweisen als die Physiothera-peut:innen. Das Stresserleben beider Berufsgruppen ist vergleichbar und insgesamt setzt die Mehrzahl aller Befragten mindestens drei von f{\"u}nf gesundheitsf{\"o}rderlichen Verhaltensweisen um (mind. T{\"a}gli-cher Obst- und Gem{\"u}severzehr, aktuelles Nichtrauchen, risikoarmer Alkoholkonsum, K{\"o}rpergewicht im Normalbereich, k{\"o}rperliche Bet{\"a}tigung nach WHO-Empfehlung), wobei dies mehr Physiothera-peut:innen als Pflegekr{\"a}ften gelingt. Im Rahmen der bivariaten Analyse zeigten sich in beiden Berufs-gruppen nur schwache Korrelationen zwischen der Gesundheitskompetenz und den Variablen des Stresserlebens sowie des gesundheitsbezogenen Verhaltens, wobei Letzteres lediglich das Bewe-gungsverhalten und den Alkoholkonsum umfasst. Schlussfolgerung: In der hier vorliegenden Arbeit kann die Gesundheitskompetenz als personale- bzw. als Handlungsressource interpretiert werden, die problemzentrierte Bew{\"a}ltigungsans{\"a}tze unterst{\"u}tzt und als prototypische Selbststeuerungsaufgabe das Stresserleben und das gesundheitsbezogene Verhalten der Fachkr{\"a}fte in geringer Weise beeinflusst.

Although there is evidence that bacteria spread from drains to the outside, there is still a lack of research data focusing on drain biofilms from hospitals. We sampled biofilms from various wards of Helios Hospital Krefeld (Germany), where comprehensive antibiotic consumption data were available. Biofilms were analysed by cell counting, isolation of relevant bacterial groups and genetic and phenotypical resistance parameters. Data were correlated with the prescribed antibiotics of the respective ward. Furthermore, an ex-situ biofilm model was employed to investigate the influence of sub-inhibitory antibiotics on the bacterial community and the prevalence of class 1 integrons. Our results show, that every ward harboured medically relevant bacterial species. While no significant differences were found in cell counts, the median prevalence of the resistance marker gene intI1 correlated with the amount of prescribed antibiotics. In contrast, phenotypical resistances showed no similar tendency. In addition, melting curve analysis data and changes in intI1 prevalence show that the composition of the bacterial community shifted depending on the biofilm and antibiotic. Based on our results we conclude, that sub-inhibitory concentrations of antibiotics have no general effect on biofilms in terms of bacterial community shift and occurrence of antibiotic resistant species. The effect depends on the initial composition of the bacterial community, the antibiotic used and the intrinsic bacterial resistance e.g. prevalence of class 1 integrons.}, language = {en} } @misc{OPUS4-2080, title = {14/2024 Zweite {\"A}nderungssatzung zur Pr{\"u}fungsordnung f{\"u}r den Masterstudiengang Biological Resources an der Fakult{\"a}t Life Sciences vom 04.09.2024}, volume = {2024}, number = {14}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20800}, pages = {3}, language = {de} } @masterthesis{Paradis, type = {Bachelor Thesis}, author = {Paradis, Fabian}, title = {Innovation and Digital Transformation: Reshaping the Future of Food Retail}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20748}, school = {Hochschule Rhein-Waal}, pages = {61}, abstract = {The aim of this bachelor thesis is to find out how the future of food retail will be influenced by digital technologies and innovations in this market.

The research question is: "What impact can Virtual Influencers have on Brand Management?". The aim is to identify the advantages and disadvantages of VIs from a Brand Management perspective. The research utilizes a literature review and comparison to evaluate key dimensions such as authenticity, credibility, engagement, diversity, flexibility and Marketing effectiveness. The results show that VIs offer significant benefits, including flexibility, adaptability, diversity, high engagement rates, increased brand awareness and cost-effectiveness. VIs can operate without time, location or health restrictions and can be precisely customized to the brand strategy. They also achieve higher engagement rates, especially with sponsored posts, and can effectively increase brand visibility and recognition. However, the study also identifies several challenges associated with VIs. These include authenticity issues, as VIs do not have real-life experiences, making it difficult to develop real emotional connections with followers. In addition, VIs may struggle to gain credibility when promoting physical products and may not be as effective at generating purchase intention as HIs. The reduced parasocial interactions and initial distrust of users are also notable drawbacks.

With the region facing significant energy challenges, including reliance on fossil fuels, limited access to electricity and high energy costs, bioethanol offers a promising alternative. The study evaluates the physical feasibility, yield differences, resource requirements, environmental impact, and socioeconomic implications of using these crops for bioethanol production. A comprehensive methodology involving laboratory experiments and literature review is employed. Results demonstrate that cassava has a higher bioethanol yield than maize, with more efficient enzymatic hydrolysis and fermentation processes. Additionally, cassava's adaptability to marginal lands, lower water usage, and reduced greenhouse gas emissions make it a more sustainable feedstock. Economically, cassava-based bioethanol production is more cost-effective and has better market integration due to the established supply chain in the region. However, the social implications, particularly food security concerns necessitate careful consideration and the development of integrated food and fuel production systems.

Hierf{\"u}r wird die Zusammensetzung von Holzmaterialien und deren m{\"o}gliche Eignung f{\"u}r die additive Fertigung analysiert. In dieser Thesis werden verschiedene Ans{\"a}tze verfolgt, um die Optimierung konventioneller Enzyme und m{\"o}glichen Enzymalternativen zu erreichen und eine Eignung dieser anhand verschiedener Methoden zu validieren. Nach der Herstellung verschiedener Materialkombinationen von Holzwerkstoffen sollen diese darauf angewendet werden, wobei das Ziel ist, die Ligninpolymerisation bei geringerem Enzymeinsatz zu erh{\"o}hen und Ressourcen wie Kosten und Energie einzusparen, um mit Hilfe des Liquid-Desposition-Modeling (LDM) erste Probek{\"o}rper herzustellen. Dabei wurden bestehende Prozessschw{\"a}chen analysiert, Fehlerursachen diskutiert und deren Auswirkungen betrachtet. Im Rahmen dieser Arbeit konnte nachgewiesen werden, dass die Enzymaktivit{\"a}t der Laccasen aus Trametes versicolor und Aspergillus sp durch Zugabe verschiedener Metallionen gesteigert werden kann. In der Anwendung an einem Modellsubstrat und Lignin zeigte sich, dass Kupfer- und Eisenionen mit der Enzymaktivit{\"a}t korrelieren. Darauf basierend wurden Testobjekte hergestellt, an denen die Wirkung nachgewiesen werden konnte.}, language = {de} } @masterthesis{Maung, type = {Bachelor Thesis}, author = {Maung, Wai Lin}, title = {Design, control and development of gas handling unit for hydrogen supply system for a 10kW fuel cell system}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20335}, school = {Hochschule Rhein-Waal}, abstract = {Hydrogen fuel cells have been gaining attentions for marine mobility application because of it's potential as a promising green technology with high energy intensity and reduced weight; Proton Exchange Membrane Fuel cell generates electric power by consuming hydrogen and oxygen as reactants. The fuel cell system consists of multiple sub-systems such as anode gas supply components, cathode air compressors with humidification systems and a cooling circuit. They all must be regulated according to the nominated working conditions of the stack, and one of the most important parameters is the hydrogen supply feed of the fuel cell system. The hydrogen supply system must be robust to handle different working conditions of the stacks such as load fluctuation, purging of water and nitrogen from anode side and subsequent pressure fluctuations. It is critical to control the anode pressure with respect to varying conditions since unbalanced H2 supply can lead to membrane failure, hydrogen starvation and drying out which can lead to deterioration and reduce the lifetime of the stack. The thesis describes the development of "Gas Handling Unit" as the effective hydrogen supply system which will be incorporated with a particle filter, switch off solenoid valve, proportional valve, pressure transmitters and a pressure safety valve for venting during critical conditions. The design and control of the gas handling unit is detailed along with material compatibility of metals and sealants polymers with hydrogen applications.

However, there is a significant challenge in chicken processing which involves the occurrence of wing breakage that impacts both the aesthetic quality of the product and raises concerns regarding animal welfare and economic sustainability. This thesis aims to investigate the underlying biological factors associated with wing damage during processing by comparing wing structures of broilers raised under different management systems. This investigation focuses on exploring the chicken wing breakage contributing factors and cultivating a better understanding of this challenge to aid the chicken processing industry. This objective will be achieved by a comparative analysis of internal wing structures with a focus on distal humeral growth plate development observed in chicken wings from broilers raised under different production systems. The packaging and selling of damaged chicken wings for human consumption is prohibited by the European Union due to the potential health risks and aesthetic reasons. Hence, the disposal of chicken carcasses with wing damage results in financial losses for the company. An internal comparative analysis of the chicken wings aided by dissection techniques as well as X-ray fluorescence (XRF) spectrometry analysis of elements present at the bone growth plates will be carried out with an intention of quantifying the structural variations in broiler wings from different management systems. By elucidating the internal features and compositions of the different chicken wings with comparison to relevant literature and recent related discoveries, this research seeks to identify biological factors potentially responsible for wing damage among different broilers, allowing further intervention strategies within the industry. The findings from this study have implications for both industry practices and animal welfare standards. By discovering potential biological root causes of wing damage, this research provides valuable insights for optimizing processing protocols and equipment design to minimize trauma to birds and enhance product quality. In addition, a deeper understanding of physiological responses of chicken to processing stress can encourage more humane and efficient poultry handling practices and management strategies to reduce losses from wastage as well as chicken welfare improvement in commercial broiler production. The overall contribution of this thesis is towards the advancement of knowledge in poultry production and the importance of considering the biological factors and internal structures of chicken wings in designing processing systems. Through collaborative efforts between researchers, stakeholders and other parties involved, the insights gained from this study will aid sustainable practices that prioritize animal welfare, product quality assurance and economic sustainability in the poultry industry.}, language = {en} } @masterthesis{Feers, type = {Bachelor Thesis}, author = {Feers, Juliana}, title = {Job Satisfaction and the Workplace Expectations of Young Professionals}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20300}, school = {Hochschule Rhein-Waal}, pages = {77}, abstract = {In the context of changing workplace norms and rapidly changing technological environments, this thesis examines the effects of expectations about the workplace on young professionals' career decisions and job satisfaction in Germany.

A Life Cycle Assessment is conducted on renewable energies in Germany, namely Wind Energy, Solar Energy, Bioenergy, and Green Hydrogen Energy. The data collection phase of the life cycle inventory was performed under several assumptions and limitations which extend to the results. It is established through the results of the study that Green Hydrogen energy holds the greatest environmental impacts out of the four energies. This impact is justified as Green Hydrogen is an energy carrier, rather than a producer. The impacts of Wind Energy, Solar Energy, and Bioenergy are compared in the absence of Green Hydrogen Energy, as they are all energy producers. It is found that the overall environmental impacts of Bioenergy are the greatest of the three, while Wind Energy has the lowest impacts. Solar Energy had greater impacts than Bioenergy in certain impact categories. Comparison of this study with previous Life Cycle Assessments reveals some similarities and differences.

One party welcomes the wolf back to Germany and sees its potential to increase the biodiversity in Germany's ecosystems and forests, one party sees the harm in the wolf by killing livestock animals such as equines (Equus), sheep (Ovis aries) and cattle (Bovine) yet another party is torn in between. Many farmers and shepherds are trapped somewhere in between in these opposing views. The return of the wolf has led to conflicts between livestock owners and the predators, necessitating effective and sustainable solutions to protect livestock. This thesis examines the status quo of LGDs as a non-lethal method for guarding livestock in the context of the wolf's return in Germany. It explores the historical use of LGDs, their reintroduction in modern German agricultural practices, and the factors influencing the success or failure. Through a comprehensive analysis of existing literature and interviews, the study investigates the socio-economic, ecological and policy-related dimensions of LGD use. Key areas of focus include the training and management of LGDs, their impact on reducing livestock loss, the attitudes and perceptions of livestock owners towards these guardian animals as well as the attitudes and perceptions of non - livestock owners. Findings indicate that LGDs can significantly reduce wolf predation on livestock when properly implemented and supported by appropriate training and management practices. Nevertheless, challenges such as initial investment costs, maintenance, and integration with other livestock protection measures need to be addressed. The research highlights the importance of education and support for livestock owners, as well as the need for policies that facilitate the use of LGDs. This concludes that LGDs can be a useful, non-lethal protection measure addition to livestock farms. However, it is found that a combination of protection measures is the most effective in protecting livestock from predators.}, language = {en} } @masterthesis{Turan, type = {Bachelor Thesis}, author = {Turan, B{\"u}sra}, title = {Islamic Banking and Finance: Supply and Demand in Germany}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-20284}, school = {Hochschule Rhein-Waal}, pages = {60}, abstract = {This paper examines the current landscape of Islamic banking and finance in Germany through two research approaches.

The experiments were performed over a period of 4 months with the goal of setting a robust calibration for carbon detection in ferroalloys. Ferrochromium ranging from 0,01 \% to 9,03 \% carbon was used as a reference material for the calibration. It was tested by using independent certified reference materials of ferrochromium but also additional ferroalloys like ferro-manganese, -silicon, - niobium, -titanium and -vanadium for the validation process. The statistical calculations were performed using the NORDTEST standards to ensure reliable results. Additionally, the drift of the machine and the detection and quantification limits were investigated. It revealed that the drift had to be applied daily, and that the quantification limit of the detector in the CS-analyzer is around 0,012 \% carbon. As a result of the statistical calculations, it appeared that the measurement uncertainty is carbon percentage dependent.

This paper attempts to addressthis gap through the use of pre-trained transformer models specially tailored for Nepali from Hugging Face including BERT, DistilBERT, ALBERT, and DeBERTa for sentiment analysis in Nepali tweets on relatively balanced datasets. The models are trained on large Nepali datasets and optimized for NLP tasks involving Devanagari scripts. To evaluate the model's performance, various tokenization strategies are investigated in order to capitalize on transformer-based embedding with the SoftMax function and confusion matrix. The outcomes of models are compared using the same datasets. The study's results shows that DistilBERT achieved the highest accuracy rate of 88\% in Nepali sentiment analysis tasks, followed by BERT and DeBERTa at 83\% and 80\%, respectively. However, ALBERT showed a low accuracy of 70\%. The result of this approach shares valuable viewpoints for the field of sentiment analysis in diverse linguistic contexts.}, language = {en} } @misc{Shrestha, type = {Master Thesis}, author = {Shrestha, Sabita}, title = {Named Entity Recognition for Nepali Text Using Pre-Trained BERT-Based Model}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19870}, school = {Hochschule Rhein-Waal}, abstract = {The popularity of using transformer-based models like Bidirectional Encoder Representations from Transformers (BERT) for various Natural Language Processing (NLP) tasks is increasing rapidly. Unfortunately, the research is very limited for low-resource languages like Nepali. This study examines the utilisation of pre-trained BERT-based NERNepal for Named Entity Recognition (NER) tasks in Nepali text. The main goal is to investigate the efficiency of the NERNepal model, which has been pre-trained and fine-tuned on Nepali corpus data for NER. This research provides new insights by evaluating the NERNepal model on two distinct datasets. It addresses unique linguistic challenges specific to Nepali. The study also offers a detailed analysis of the model's strengths and weaknesses. By focusing on diverse datasets, this study shows how adaptable the model is and how its performance varies. These aspects have not been explored extensively before. The EverestNER dataset is one of the largest human-annotated datasets in Nepal so far, and the Nepali_NER dataset is also BIO-annotated for the NER task, which helped to compare the model's prediction. The performance was better on the Nepali_NER dataset in comparison with another selected dataset. The EverestNER dataset contained many complex words for ORG connected with many tokens for a single entity with different contextual meanings and different annotations for the same word in different tokens as per context. Because of this, it created more confusion for the prediction, especially for the ORG entity. It had a similar issue with another dataset as well, but the label annotation was better in comparison. Furthermore, the research tries to clarify the difficulties and constraints related to utilising pre-trained BERT models for NER in low-resource languages such as Nepali. The study focuses on research areas on the efficacy of the model and its performance on two different datasets. Post-training with the EverestNER train dataset was attempted, but due to computational resource limitations, only a maximum of 3 epochs was possible, which did not improve the evaluation. It also has implications for enhancing language processing tools for Nepali. The results show the ability of a pre-trained BERT-based model to improve NER skills for Nepali text. However, further study is required to overcome the current obstacles to identifying complex words. The availability of high computational resources and the possibility of combining other NER approaches with a transformer-based model could increase the performance and robustness of the model.

In many parts of the world, access to safe drinking water is limited, leading to various waterborne diseases. Solar water disinfection(SODIS) is a simple and cost-effective method used to purify water using sunlight, where itinactivates the pathogens and makes the water safe for consumption. This disinfection process involves filling polyethylene terephthalate (PET) bottles with water and exposing them to sunlight for a specified period. The aim of this thesis is to develop a working prototype that exploresthe automation of SODIS on a small-scale using Arduino Due, a microcontroller board that offers advanced features for automation. The prototype consists of the necessary parts to perform SODIS automatically. In conventional SODIS, it is assumed that the required SODIS criteria are met within 6 hours of a sunny day. In contrast, in the prototype microcontroller pumps the water into the PET bottle, monitors sunlight exposure for 6 hours, determines disinfection, and then pumps out the water for consumption only when the threshold values for irradiance are met. If the conditions are not met, the exposure is extended by an hour each time and checked again. The prototype automates the SODIS on a small-scale using cost-efficient components. However, the prototype lacks oxygenation capacity, and there is a possibility of entering an infinite loop if the irradiance values are not met for a long time.

We want to leverage their uniqueness as an intended game mechanic and see in what context these strategies can work. To achieve these goals, we researched already existing integrations of generative AI features in games and entertainment as well as possible connections to game mechanics and systems that are not related to AI. Based on this, we created 4 prototypes of conversational games with generative AI characters, which allowed the AI to create anomalous responses and did not limit the player freedom of what they may input. In our 36 participatory design sessions, we found that anomalous user and AI behavior can have a positive influence on the player's experience if a game's story is set up in a way that it can allow new and diverging story threads, that are created by the player and AI, to be integrated and if there are supplementary game mechanics, that allow the player to follow the intended story and complete the game.}, language = {en} } @masterthesis{Kottek, type = {Bachelor Thesis}, author = {Kottek, Nick}, title = {Echtzeit-Erkennung von Gesten des deutschen Fingeralphabets mithilfe eines Convolutional Neural Networks}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19768}, school = {Hochschule Rhein-Waal}, pages = {58}, abstract = {Sign language is an important factor in the integration of deaf and hard of hearing people into society.

This bachelor thesis investigates the impact of LGWs on indoor environmental quality, employees' well-being, and performance in the offices of the Facility Management Department of Hochschule Rhein-Waal (HSRW) - Kleve campus. A hybrid methodology is adopted, combining sensor measurements of physical parameters and a self-developed questionnaire assessing perceived LGW impact. The sensors are set up in four offices, three of which featured LGWs, while the questionnaire is distributed online to workers before and after the LGW installation. Eight workers participated in the study, of which 62.5 \% were female, and 37.5 \% were male, with age range between 25 and above 45 years old. The results indicate a positive overall impact of LGWs on office environmental quality and employee well-being. The CO2 concentration was reduced on average by 30 ppm, whereas the relative humidity was increased, on average, by approximately 6 \%. Hence, the LGWs enhanced slightly the air quality in the offices. Moreover, the target group claimed that their motivation level, on average, was raised by 15\% after exposure to the LGWs. Hence, half of them agreed that the LGWs impacted their performance positively. However, challenges emerged concerning LGW technical design and employee engagement with the research. Despite obstacles, the study suggests potential for future improvements in methodology and technical aspects, offering promising project ideas for further research. Furthermore, the overall positive impact of LGW in this study has proven that integrating such systems into work environment can boost the motivation level of the workers and improve the environmental quality in workspaces.}, language = {en} } @masterthesis{Tebest, type = {Bachelor Thesis}, author = {Tebest, Marie}, title = {Schneller Nachweis der Methicillin-Resistenz bei Staphylokokken-Isolaten Vergleich verschiedener Methoden}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19727}, school = {Hochschule Rhein-Waal}, pages = {74}, abstract = {Methicillin Resistente Staphylococcus aureus (MRSA) geh{\"o}ren zu gef{\"u}rchteten Erregern eines bunten Bildes von Infektionen, die bis zu einer Sepsis reichen k{\"o}nnen.

Edible insects offer comparable nutrition to traditional protein sources while requiring minimal resources for farming. However, unsustainable harvesting practices endanger wild insect populations. To counter this, insect farming emerges as a promising strategy, leveraging efficient conversion rates and organic waste utilization. This paper explores how edible insects can integrate into circular food economies, converting organic waste into valuable resources, bolstering food and feed security, and mitigating waste. Specifically, it examines the potential of insects like black soldier fly larvae, yellow mealworms, houseflies, and house crickets in SSA for waste management and sustainable nutrition. The discussion encompasses insect abundance, waste utilization, economic cycles, and environmental benefits. Furthermore, it explores the quality and quantity of available urban organic waste streams, waste-to-insect combinations, and the socioeconomic implications of insect farming, including gender dynamics and consumer acceptance.

To assess its potential, three expert interviews were conducted in the beginning with the key stakeholders of a Silphie supply chain. These stakeholders included the fiber producer OutNature, the seed distributor Donau-Silphie, and the CO2 certification company Positerra. Through these interviews, the necessary conditions for establishing a Silphie cultivation region for paper production were determined. Subsequently, the attitudes of local farmers towards cultivation and further use of the plant were surveyed. Additionally, the potential for CO2 sequestration of Silphie was assessed and compared with the opinions of the farmers. The results from the interviews and the survey were used to identify patterns using explorative data analysis and descriptive statistics methods, enabling the prioritization of potential farmers in the future. The evaluation of the methods revealed an interest in cultivation and fiber production under certain conditions. The most important prerequisites include profitability, secured take-off agreements, and the suitability of using the plant as fodder. Consequently, farmers with a larger farm size who cultivate silage maize for biogas production are most willing to grow Silphie. By geographically mapping potential Silphie areas, two preferred catchment areas were identified where the chance for a cultivation region is favorable due to existing infrastructure and farmer interest. Furthermore, a comparison of the required environmental conditions with those present in OWL was conducted and mostly deemed accurate.

By focusing on routine hematology, biochemistry, and microbiology tests, the study aims to revolutionize clinical laboratory processes, improve diagnostic accuracy, and enhance patient care. Through an extensive approach regarding specimen collection of blood and the utilization of automated medical devices, this study sheds light on the advantage of Medi to streamline operations within clinical laboratories. The research methodically assesses the impact of Medi on laboratory workflows and patient outcomes, employing a user-centric design to ensure the software meets the practical needs of healthcare professionals. Medi demonstrated significant improvements in laboratory efficiency, with streamlined workflow. Key findings include the standardization of blood specimen collection procedures, limiting blood-tube-selection errors, and a positive impact on laboratory operations. The software facilitated a more cohesive integration of clinical data, contributing to better-informed decision-making and improved patient care. By comparing these outcomes with the current state of clinical diagnostics, Medi's introduction represents a transformative shift in laboratory operations. It not only addresses the pressing need for advanced assistive technologies in the clinical laboratory settings but also sets a new standard in patient care. This research underlines the potential of integrating software solutions with existing laboratory technologies, paving the way for a new era in clinical testing.}, language = {en} } @misc{OPUS4-1947, title = {03/2024 Zweite {\"A}nderungssatzung zur Ordnung {\"u}ber die Aufbewahrung, Aussonderung, Archivierung und Vernichtung von Dokumenten der Hochschule Rhein-Waal (Aufbewahrungsordnung) vom 01.03.2024}, volume = {2024}, number = {03}, organization = {Hochschule Rhein-Waal}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-19474}, pages = {4}, language = {de} } @misc{ShujaUdDin, type = {Master Thesis}, author = {Shuja Ud Din, Aneeba}, title = {"SCHOOL FEEDING AND PUBLIC FOOD PROCUREMENT PROGRAMS AS A POLICY INSTRUMENT TO PROMOTE SMALLHOLDER FARMING AND SUSTAINABLE FOOD SYSTEMS - A SYSTEMATIC LITERATURE REVIEW}, school = {Hochschule Rhein-Waal}, abstract = {Family farms and smallholders have been kept out of the market niche due to their competition with larger multinational corporations. Smallholder farmers can enter the food market easily by linking them with school feeding programs. National school feeding programs exist globally. However, food quality is a major factor in the success of these programs in enhancing student nutrition. This offers opportunities for family farms to supply nutritious, local organic produce to regional schools and gain access to the food market in urban areas. Students and farmers can benefit from this integration along with all supply chain contributors. Nevertheless, proper management of these supply chains, programs, and farms is a necessity. In this review, the impacts of local procurement for school meal programs are discussed with data from different national programs. Perspectives of farmers, distributors, school management, students, and parents are discussed to assess the advantages of buying from family farms. Challenges faced in the process of procurement from smallholders and associated risks are also examined. Social actors including producers, distributors, consumers, and government that participated in these studies give their opinions on school feeding programs. The main problems arise from the lack of budget and incentives available to farms and faulty logistics that can affect quality and quantity of school meals. Organizational strategies to promote sustainable supply chains and investment in agriculture policies are practical solutions for these challenges.}, language = {en} } @masterthesis{Zabun, type = {Bachelor Thesis}, author = {Zabun, Elif Ezgi}, title = {Fermentation of Pyrus communis var.

Yeast metabolism is responsible for the aromatic compounds produced during fermentation. Different yeasts create different aromatic compounds, or different concentrations of compounds during fermentation because of the metabolic differences between yeasts. In this bachelor thesis, the effect of utilizing native yeasts on the sensory properties of the produced alcoholic beverage is evaluated. A total of 83 isolates were obtained from the surface, juice, and 7-days-rested juice of fresh pears of Conference variety. Among these isolates, 19 of them were identified as yeast samples. For native yeast sample used in sensory analysis, among known species in the sample, Saccharomyces cerevisiae has the highest relative abundance, followed by Saccharomyces eubayanus. The odor scores were significantly higher for native yeast sample points than the odor scores of LT8 points. The difference between the total sensory analysis scores was not significant. The results showed that the native yeast performed as good as the commercial yeast in terms of sensory properties, with a significantly better odor perception and higher production of ethanol.}, language = {en} } @misc{Zimmermann, type = {Master Thesis}, author = {Zimmermann, Laura}, title = {Matching im Gesundheitswesen: Eine Analyse relevanter Faktoren zur erfolgreichen Besetzung {\"a}rztlicher Positionen im Krankenhaus mit Handlungsempfehlungen}, school = {Hochschule Rhein-Waal}, abstract = {Hintergrund - Seit Jahren steigt in Deutschland der Bedarf an {\"a}rztlichem Personal.

Fraglich ist jedoch, wie {\"A}rzte in dieser F{\"u}lle an Optionen die f{\"u}r sie ideale Stelle finden k{\"o}nnen. Ein Stellenportal soll die Br{\"u}cke zwischen Stellensuche und Stellenbesetzung bilden. Ziel - Das Ziel dieser Masterarbeit ist es, relevante Faktoren und gegenw{\"a}rtige Herausforderungen im {\"a}rztlichen Bewerbungsprozess zu identifizieren. In Anlehnung daran soll entschieden werden, inwiefern ein digitales Stellenportal den bestehenden {\"a}rztlichen Stellenmarkt verbessern kann, und welche Alternativen bestehen, um die Effizienz und Qualit{\"a}t im {\"a}rztlichen Bewerbungsprozess zu verbessern. Methodik - Um die Forschungsfrage zu beantworten, wurde eine qualitative Studie zu Bewerbungsprozessen im Krankenhaussektor durchgef{\"u}hrt. Im Rahmen dessen wurden Experteninterviews mit {\"A}rzten sowie Personalverantwortlichen in Krankenh{\"a}usern gef{\"u}hrt. Daneben wurde auch eine quantitative Befragung mit {\"A}rzten durchgef{\"u}hrt, um die qualitativen Aussagen der Interviews mit quantitativen Daten zu untermauern. Ergebnisse - {\"A}rzte bewerben sich {\"u}berwiegend initiativ oder nutzen ihr pers{\"o}nliches Netzwerk, um eine Neuanstellung zu finden. Dabei sind vor allem das Team und die Lage des Krankenhauses relevant. Krankenh{\"a}user ver{\"o}ffentlichen Stellenausschreibungen {\"u}berwiegend auf ihrer Webseite und im Deutschen {\"A}rzteblatt. Digitale medizinische Stellenportale werden bislang weder von {\"A}rzten noch von Krankenh{\"a}usern in hohem Maße genutzt. In nahezu allen Krankenh{\"a}usern sind derzeit {\"a}rztliche Stellen unbesetzt, die mit langen Nachbesetzungszeiten verbunden sind. Daher halten Krankenh{\"a}user ihre Anforderungen an Bewerber m{\"o}glichst gering und beschr{\"a}nken ihre Einstellungsvoraussetzungen h{\"a}ufig auf ausreichende Sprachkenntnisse und eine stellengerechte Qualifikation. Schlussfolgerungen - Der demografische Wandel und der Fachkr{\"a}ftemangel erfordern ein Umdenken seitens der Krankenh{\"a}user im {\"a}rztlichen Bewerbungsprozess. Die Entwicklung eines digitalen Stellenportals f{\"u}r {\"a}rztliches Personal kann den bestehenden Herausforderungen nur geringf{\"u}gig entgegenwirken.
