In Germany, administrative specifications must be strictly observed for N (nitrogen) and P (phosphorus) fertilization. There are several factors need to be taken into account when calculating nutrient fertilizer levels. The main calculation factor for the nutrient amounts for N, P and K (potassium) is the expected yield respectively a 3-year yield average. Furthermore, the soil nutrient contents have to be considered when calculating the P and K fertilizer quantities. Possible remaining harvest residues (for example, straw from the previous harvest) including the P and K values within these residues have to be subtracted from the current P and K fertilizer values.

Für die praktische Landwirtschaft sind Informationen über die Verteilung der Bodenart auf den Nutzflächen von Bedeutung. Insbesondere der Tongehalt hat einen wichtigen Einfluss auf das Wasser- und Nährstoffspeichervermögen der Böden (SCHEFFER / SCHACHTSCHABEL, 1998) und ist somit für die Ertragsbildung von entscheidender Bedeutung. Doch eine entsprechende klassische klein- räumige Bodenkartierung ist kosten- und zeitaufwändig. Mit Hilfe der Sensorik kann der Kartieraufwand eingegrenzt und somit reduziert werden (DOMSCH 2004; DURLESSER 1999). Im Forschungsprojekt „Precision Farming als Instrument der interdisziplinären potentialorientierten Landnutzung“ (kurz PIROL) der Fachhochschule Osnabrück wird im Teilprojekt Bodenkunde/Bodensensorik ein Bodensensorsystem entwickelt. Neu an diesem System ist die gleichzeitige Erfassung mehrerer Bodenparameter. Ziel des Teilprojekts ist es, Möglichkeiten einer beprobungsarmen bzw. –freien Flächenkartierung zu schaffen.

The career trajectories, professional performance, and satisfaction of graduates are often not known to the coordinators of study programs, left alone the demands of the labor market. Existing studies and surveys are often only cross-sectional snapshots of relatively large national or international graduate cohorts, often surveying multiple scientific disciplines in one survey. The domineering amount of studies for the biomedical disciplines is also focusing on and targeting the US American educational system and labor market, which differs substantially from the system for professional training established in the Bologna area. As a result, individual programs often face substantial difficulties identifying meaningful information to optimize their training to the demands of the labor market. Since academic programs of full, Ph.D. awarding universities in Germany traditionally tend to consider themselves primarily responsible for the demand of academia itself. The relationship between a student and its supervisor during a research project (e.g. MSc or Ph.D. thesis) in the natural sciences is often best described by a master-apprentice relationship, which in itself also only reflects the need of the academic job market. This poses a major problem since only an estimated 5-15% of all graduates will remain in academia long term. Detailed knowledge about the current demands of the labor market is important to ensure the success of graduates when competing in the whole labor market. Large, cross-sectional studies unfortunately often are not able to identify the individual strength and weaknesses of a program, and an in-depth, detailed analysis of the labor market is usually beyond the capacities of an individual program. This searches for a reliable source of information, which can be analyzed with limited resources a relevant one. Theoretically, the community of program alumni should be easy to access the source, containing all relevant information. This thesis, therefore, tries to probe a specific alumni community for relevant and actionable information regarding the career trajectory of graduates. Together with current students and alumni, a survey was developed and communicated to the alumni community with the following results: • Mainly recently graduated Alumni answered the survey. Accordingly, the responders were largely in early post‐graduation career stages, many still in their first post‐graduation employment, with an overrepresentation of academic research. • Studying in Germany increased the professional occupation in Germany from 20% before to 60% afterward • Although the labor market proofed to be more diverse than anticipated during the drafting of the survey, metric concerning satisfaction, influence on hiring, and other parameters were similar between different groups of alumni • This analysis grouped the surveyed alumni into two groups, working within or outside academia (Academics or non‐Academics, respectively) and either holding or not holding a Ph.D. title or equivalent doctorate in both work environments, leading to four sub‐groups. • These two groups and four subgroups revealed major differences concerning the competence profiles investigated. • A particularly critical parameter for professional development is the first occupation after graduation and the transition period to that occupation • The scientific knowledge and competence in biomedical sciences were considered surprisingly unimportant. • Of particular importance were all aspects of communication, the ability to handle large sets of data, and general IT‐competence. • To keep the education and training of a graduate program adequate to the changing demands of the current labor market, easily modifiable program structures and effective feedback mechanisms need to be implemented. Therefore, it appears the alumni survey has the potential to produce meaningful and actionable information to construct curricular relevant to the demands of the labor market. However, special strategies need to be developed to ensure the participation of valuable older alumni to avoid overrepresentation of academic researchers. Breaking up the rather lengthy survey into a longitudinal structure with shorter surveys at a time would likely result in improved quantity and quality of data. Surveying alumni through a consortium of similar, close collaboration programs would also help to contextualize information and to establish reliable benchmarks.

Obwohl es zahlreiche Arbeiten zum Requirements Engineering im Allgemeinen gibt, ist über die Ermittlung generischer und innovativer Anforderungen, wie sie in intersektoralen Informations-ketten eine Rolle spielen, wenig bekannt. Das Projekt IKM health zielt auf die Entwicklung von Referenzmodellen für Informationsketten zur Patientenversorgung ab. Forschungsfrage dieser Studie war, wie Informations- und Prozessanforderungen generiert werden können. Vor diesem Hintergrund wurde mit der Analyse von Leitlinien begonnen, deren Empfehlungen anschließend im Rahmen von Delphi-Befragungen und Experteninterviews zur Diskussion gestellt wurden. Trotz der sich zeigenden Heterogenität war es mit Hilfe des hier vorgestellten multimethodischen Vorgehensmodells möglich, passende Anforderungen zu erzielen und in UML zu modellieren.
