In this paper, the method is applied for the rapid evaluation of freshness and monitoring the aging of animal meat and fish. A novel chromatographic sensor was developed with a deep UV LED-based photometric detection unit (255–265 nm), an original flow cuvette and registration scheme; the processing of a chromatogram with the sensor takes approximately 15 min. Strict isochronism between the elution of ATP metabolites, mainly hypoxanthine (Hx) and inosine monophosphate (IMP), and the time of maturation of meat or fish, was discovered. A new freshness index H* = [Hx]/[IMP] was introduced, which is proportional to the instrumental delay time in the FPMLC chromatograms: the H* index < 0.5 indicates the presence of inosine monophosphate (IMP) and the high quality of the meat or fish. Reasonably strong correlations were revealed between data obtained by FPMLC and total volatile basic nitrogen TVB-N (for fish) or volatile fatty acids VFA (for meat) content. Moreover, putative nucleotide salvage and an increase in the concentration of IMP were observed in fish after heat treatment using the FPMLC sensor and NMR technique.

Being divided into several domains (for instance, text steganography, digital media steganography, and network steganography), it is crucial to provide a unified terminology as well as a taxonomy that is not limited to some specific applications or areas. A prime attempt towards a unified understanding of terms was conducted in 2015 with the introduction of a pattern-based taxonomy for network steganography. Six years later, in 2021, the first work towards a pattern-based taxonomy for steganography was proposed. However, this initial attempt still faced several shortcomings, e.g., the lack of patterns for several steganography domains (the work mainly focused on network steganography and covert channels), various terminology issues, and the need of providing a tutorial on how the taxonomy can be used during engineering and scientific tasks, including the paper-writing process.

As the consortium who published this initial 2021-study on steganography patterns, in this paper we present the first comprehensive pattern-based taxonomy tailored to fit all known domains of steganography, including smaller and emerging areas, such as filesystem steganography and cyber-physical systems steganography. Besides, to make our contribution more effective and promote the use of the taxonomy to advance research on steganography, we also provide a thorough tutorial on its utilization.

While the use of technology influences users’ behavior in a pace that is affected by the technology introduction to the market, legal activities can be driven by the society as the results of such interactions. This scenario analysis- based research focuses on a classic but fictional food recommender system and the ethical issues that might occur from its usage. The recommender system is taken here as an example of machine learning-based systems (MLS) that can often be found in the individual, business and administrative applications. The research compares the existing legal solutions, with the focus on the GDPR legislation, and the discovered ethical issues. The ethical analysis is led along the ALTAI principles suggested by the European Commission, the common good approach as well as the general principles constituted in human rights. While the GDPR-based analysis showed that this data- and privacy-based legislation addressed most of the identified ethical issues, questions related to the common good approach in the context of environment and mobility that arise due to the wide spectrum of the MLS usage require further legal discussion. The application of the two approaches shows that conducting the ethical and legal analysis is beneficial for both the designers of such MLS as well as the legal actors. The findings can enhance the design and functions of a user-facing MLS as well as influence or validate legal activities.

While the number of ethical principles in the IT design is growing, they do not necessarily apply to specific products, which means developers and e.g. purchasing agent need to contextualize them for each specific IT product. This paper describes an actionable artifact that allows assessment of ethical non-functional requirements of an information system through operationalization of ethical values, Ethical Software Assessment Tool (ESAT). It is based on a survey of values that are currently considered in research and practice as well as in legal initiatives in IT context. The ethical approach and principles operationalized in ESAT are presented and discussed.

Einhergehend mit der Zunahme der Nutzung des Internets in vielen Lebensbereichen steigt auch die Wichtigkeit für Unternehmen, einen repräsentativen Auftritt zu etablieren. Für kleine und mittlere Unternehmen bedeutet das Betreiben und Pflegen einer Onlinepräsenz oftmals einen hohen finanziellen und zeitlichen Aufwand. Ziel des vorliegenden Arbeitspapiers ist es, kleinen und mittleren Unternehmen eine Alternative zu herkömmlichen Content Management Systemen darzulegen und sie bei der Entscheidungsfindung zu unterstützen. Zur Beantwortung der Forschungsfragen wurde der methodische Ansatz einer Literatur- und Internetrecherche verwendet. Aus der Analyse konnten drei Online Business Plattformen identifiziert, sowie deren Vor- und Nachteile gegenüber Content Management Systemen dargestellt werden. Anschließend wurden Kriterien definiert und Empfehlungen dargelegt, welche kleine und mittlere Unternehmen im Entscheidungsprozess unterstützen sollen. Letztlich wurden die Einrichtung sowie die wichtigsten Funktionen einer Plattform dargestellt. Die Ergebnisse zeigen, dass die Nutzung einer Onlineplattform für lokal begrenze Unternehmen mit geringen Anforderungen an die Funktionalität und hoher Kostensensibilität eine sinnvolle Alternative ist. Abschließend wurde anhand des realen Fallbeispiels „Google My Business“ (seit 2022: „Google Business Profile“) auf die Funktionen sowie Vorteile und Möglichkeiten einer solchen Plattform eingegangen. N2 - Digitalization is one of the big challenges of our time. Along with the increased online life, the importance for companies to establish a representative online presence is growing as well. Especially for small and medium size companies, the operation and maintenance of an online presence means a high effort in terms of time and financial investment. The aim of this study is to provide an alternative to common content management systems for small medium size companies. In addition, they should be supported in the decision making process. To answer the research questions the methodical approach of a literature and internet research was used. From the analysis, three online business platforms were identified and their advantages and disadvantages compared to content management systems were presented. Subsequently, criteria were defined and recommendations were presented, which should support small and medium-sized enterprises in the decision-making process. Finally, the setup as well as the most important functions of a platform were presented. The results show that the use of an online platform is a sensible alternative for locally limited companies with low functionality requirements and high cost sensitivity. Finally, the functions as well as advantages and possibilities of such a platform were discussed on the basis of the real case study "Google My Business" (since 2022: "Google Business Profile") T3 - Schriften des Instituts für Betriebliche Anwendungssysteme - 23/1 KW - Digitalisierung KW - KMU KW - Google Business Profile KW - Online Präsenz KW - Online Plattformen KW - Online-Marketing KW - Geschäftsmodell KW - Plattform KW - Klein- und Mittelbetrieb Y1 - 2023 U6 - http://nbn-resolving.de/urn/resolver.pl?urn:nbn:de:kobv:522-opus4-28853 SN - 2198-090X VL - 11 PB - Technische Hochschule Brandenburg CY - Brandenburg an der Havel ER - TY - GEN A1 - Stockhausen, Pablo A1 - Johannsen, Andreas A1 - Maurer, Robert T1 - Machine-Learning Verfahren für eine nachhaltige Letzte-Meile-Logistik N2 - Dieser Beitrag entwickelt ein Konzept zur praktischen Umsetzung eines Machine- Learning Verfahrens zum Lösen von Vehicle Routing Problemen im Kontext einer nachhaltigen “Letzte-Meile”-Logistik, welches durch einen Prototyp umgesetzt und getestet wurde. Der Prototyp basiert auf dem “Reinforcement Learning”-System und verwendet als Algorithmus “REINFORCE mit Baseline”. In einer Vergleichsanalyse wurde der Prototyp mit dem bekannten Vertreter Google-OR, anhand von zwei Anwendungsszenarien, verglichen. Der Prototyp überzeugt dabei in der Laufzeit und dem Automatismus. Es konnte festgestellt werden, dass eine Verwendung von Lernenden-Systemen für das Vehicle Routing Problem sich bei nur bei einem größeren Stoppvolumen und einer erweiterten IT-Infrastruktur empfiehlt.
