Vor diesem Hintergrund ist es nicht verwunderlich, dass die kindliche Sprachentwicklung unter besonderer elterlicher, erzieherischer und {\"a}rztlicher Beobachtung steht. In der nationalen Fachliteratur wird immer wieder zur Diskussion gestellt, dass die Zahl von Sprachentwicklungsst{\"o}rungen einschließlich der daraus resultierenden Lern- und Verhaltensst{\"o}rungen in den letzten Jahren drastisch angestiegen sei. Um dieser Frage nachzugehen, wurden die vollst{\"a}ndigen Datens{\"a}tze des Kinder- und Jugend{\"a}rztlichen Dienstes (KJ{\"A}D) der Einschulungsuntersuchungen der Jahre 2008/2009, 2009/2010 und 2010/2011 des Gesundheitsamtes Dresden ausgewertet. F{\"u}r die Erfassung von Sprachentwicklungsauff{\"a}lligkeiten kommt seit dem Schuljahr 2004/05 das Screening des Entwicklungsstandes S-ENS zum Einsatz. Ziel dieser Arbeit war es, die aktuellen Pr{\"a}valenzraten kindlicher Sprachentwicklungsauff{\"a}lligkeiten in Dresden zu ermitteln. F{\"u}r die Beurteilung m{\"o}glicher sozialer Einfl{\"u}sse auf die Sprachentwicklung wurde ein weiterer unabh{\"a}ngiger Datensatz der Kommunalen B{\"u}rgerumfrage aus dem Jahr 2010 hinzugezogen. Die Ergebnisse best{\"a}tigten im Untersuchungszeitraum einen leichten Anstieg der auff{\"a}lligen Testergebnisse des KJ{\"A}D von insgesamt 2,8 Prozent, welcher zwischen den einzelnen Orts{\"a}mtern sehr stark divergiert. Der Extremgruppenvergleich zeigte anhand der Daten der KBU m{\"o}gliche Hinweise f{\"u}r soziale Einfl{\"u}sse auf die Sprachentwicklung des Kindes auf. Die Ergebnisse unterscheiden sich mit 12,5 Prozent zwischen den Punktwertresultaten des S-ENS und der Gesamtbeurteilung des Sprachergebnisses der {\"A}rzte deutlich. Die Ergebnisse dieser Arbeit best{\"a}tigen keinen eindeutigen Anstieg der kindlichen Sprachauff{\"a}lligkeiten in Dresden. Eine weitere Erfassung des Sprachstandes mit Hilfe des S-ENS sollte kritisch {\"u}berdacht werden.

Striking are the various types of information with regard to the duration of application, shape and intensity. Because of the missing evidence for sensibility of application intensity this study aimed to determine influential parameters with moderate cold (11°C) for improving the intensity control. 15 healthy subjects aged 23.2±1.26 were tested. The parameters BMI, fat mass and muscle mass were recorded. All subjects received a cold application by the invented and developed IceCube at the right knee joint for 15 minutes. The temperature was measured for six times with an infrared thermometer at five standardized points of the knee joint. During application and till the last measurement subjects were immobilized. The applied cold application resulted in a significant decrease of temperature in all measuring points concerning the pre-post-comparison. 20 minutes after removing the cuff significant temperature increases in 3 measurement points, still keeping below starting level, were remarked. Furthermore it is evident that the temperature differences of the muscular measuring points are significantly higher than those of the not muscular measuring points. Besides a higher fat portion leads due to the isolation effect in relation to musculature to significantly fewer variations in temperature. This realization is to be considered for an adequate intensity regulation. In order to confirm the force of expression of the results, it requires further investigations with higher test person numbers.}, language = {en} } @misc{MartinBraunMicheletal., author = {Martin, Titus and Braun, Alexander and Michel, Sven and Meisinger, Matthias and Prill, Robert and Kirschner, Jana and Vorwerg, Susan}, title = {The objective measurement of individual work-related functional performance in the context of medical rehabilitation - First results of a case study with the ERGOS - Work Simulator}, series = {The International Disabled People`s Day - XXIth edition - Life without Pain / Healthy Children - Healthy Europe}, journal = {The International Disabled People`s Day - XXIth edition - Life without Pain / Healthy Children - Healthy Europe}, publisher = {Oficyna Wydawnicza Klubu Literackiego "Inspiracje"}, address = {Zgorzelec}, isbn = {978-83-88380-73-0}, pages = {17}, abstract = {In the context with the high meaning of work for the human, the enormous job-specific demands on psychophysical performance and the need for a rapid return to working life in case of injury or disease, the importance of the diagnosis of occupational performance in therapy is high.

In case of illness with rehabilitative requirements should therefore medical therapy be dovetailed with work and work-related activities. That connection is a necessary development of rehabilitative care system in Germany, not least in view of the legal order of the German Pension Insurance to help injured patients and to support their return to work. In the work-related orientation of medical rehabilitation is the professional life of rehabilitation involved in all phases of therapy. The instruments for the diagnosis of occupational problems are both objectively and subjectively oriented Questionnaires with external and self-assessment, FCE systems (functional capacity evaluation) and medical documentation systems. The Ergos® Work Simulator is a psychophysical FCE system, which captures the individual motor skills in relation to the performance of job-specific requirement profiles. The evaluation of job performance is based on a profile pool of about 14,000 professional activities.

This kind of injury is mainly based on intrinsic factors such as structural overload which accounts for 17\% of all moderate and severe competition injuries. Following knee and ankle joint, hamstrings are the third most common structure to suffer from injuries. As previous reviews show, eccentric training, such as the Nordic Hamstring Exercise (NHE), can reduce hamstring injuries. However, in those reviews other sports in addition to soccer were also examined in one sample. Purpose: The aim of this review is to synthesize the best available evidence on the effectiveness of the NHE as an intervention in the prevention of hamstring injuries in soccer players. Methods: The search for the studies was done in the PubMed, PEDro, Cochrane Library and EB-SCO databases. There was no language or time restrictions. Titles, abstracts and full texts of the respective studies were verified by two independent reviewers and selected using the inclusion criteria. In addition, critical evaluation tools were used to assess the methodological qualities of the respective studies followed by data extraction in JBI SUMARI. Meta-analysis was performed. Results: Four studies were included in this systematic review. Three studies compared NHE as an intervention with conventional football training and one study conducted hamstring curls as a control intervention. The duration of the studies ranged from 2.5 to 6.75 months, with a total of 28312 NHE sessions and 25918 training sessions in the control groups. The intervention groups showed a total of 30 hamstring injuries and the control groups developed a total of 80 injuries. A sample of 1780 soccer players were examined, 909 in the intervention groups and 871 in the control groups. The overall mean odds' ratio was significantly below one (95\% CI, P= 0.335). The probability of suffering a hamstring injury was between 0.22 and 0.53 times lower in the intervention group than in the control group. The test for heterogeneity showed no significance (I² = 9). Conclusion(s): The NHE can help to reduce hamstring injuries in football players. However, due to the small number of studies included, the result should be interpreted with caution and more clinical studies should be conducted in the future. Implications: Looking at the total number of days lost per player in a season, professional football has a total of approximately 25,900 days lost, which is three times more than in other sports. Every injury is associated with lost time and additional costs. This review aimed to examine a cost-efficient exercise for its preventive effect.

The output current of the device is saturated and clearly modulated by the base voltage. Further, the silicon collector of the GBHT is replaced by germanium to improve the device performance. This enabled the collector current to be increased by almost three orders of magnitude. Also, the common-emitter current gain (Ic/Ib) increased from 10-3 to approximately 0.3 for the newly designed device.

In this study, we fabricated and analyzed a novel graphene-based transistor, which resembles the structure of the barristor but uses a different operating condition. This new device, termed graphene adjustable-barriers transistor (GABT), utilizes a semiconductor-based gate rather than a metal-insulator gate structure to modulate the device currents. The key feature of the device is the two graphene-semiconductor Schottky barriers with different heights that are controlled simultaneously by the gate voltage. Due to the asymmetry of the barriers, the drain current exceeds the gate current by several orders of magnitude. Thus, the GABT can be considered an amplifier with an alterable current gain. In this work, a silicon-graphene-germanium GABT with an ultra-high current gain (ID/IG up to 8 × 106) was fabricated, and the device functionality was demonstrated. Additionally, a capacitance model is applied to predict the theoretical device performance resulting in an on-off ratio above 106, a swing of 87 mV/dec, and a drivecurrent of about 1 × 106 A/cm2.}, language = {en} } @incollection{StrangfeldBoeluekSzaboetal., author = {Strangfeld, Matthias and B{\"o}l{\"u}k, Oguzhan and Szabo, Peter and Meier, Martin and Meyer, Antoine and Sliavin, Yaraslau and Motuz, Vasyl and Egbers, Christoph}, title = {Thermo-electrohydrodynamic convection in a dielectric fluid layer with volumetric heating}, series = {GALA-Fachtagung "Experimentelle Str{\"o}mungsmechanik", 6.- 8.

However, whether there is synchronisation of these strategies at the entire community level is unclear. Here, we combine trait data for 2800 above- and belowground taxa from 14 trophic guilds spanning a disturbance and resource availability gradient in German grasslands. The results indicate that most guilds consistently respond to these drivers through both direct and trophically mediated effects, resulting in a 'slow-fast' axis at the level of the entire community. Using 15 indicators of carbon and nutrient fluxes, biomass production and decomposition, we also show that fast trait communities are associated with faster rates of ecosystem functioning.
