Auf dem Weg zur individualisierten Medizin - Grid-basierte Services für die EPA der Zukunft.

Personalized Medicine is of paramount interest for many areas in Medical Informatics. Therefore genotype data as well a phenotype data about patients have to be available. This data will be stored in Electronic Health Records or – patient controlled - in Personal Health Records. As the amount of (raw) data is rising continuously, methods for a secure data administration have to be found. Grid Services offer data storage, can support data retrieval and the presentation of the data. The basic security services could be provided by the German health professional infrastructure, but there are many security challenges to be faced

Contribution of online trading of used goods to resource efficiency : an empirical study of eBay users

This paper discusses the sustainability impact (contribution to sustainability, reduction of adverse environmental impacts) of online second-hand trading. A survey of eBay users shows that a relationship between the trading of used goods and the protection of natural resources is hardly realized. Secondly, the environmental motivation and the willingness to act in a sustainable manner differ widely between groups of consumers. Given these results from a user perspective, the paper tries to find some objective hints of online second-hand trading’s environmental impact. The greenhouse gas emissions resulting from the energy used for the trading transactions seem to be considerably lower than the emissions due to the (avoided) production of new goods. The paper concludes with a set of recommendations for second-hand trade and consumer policy. Information about the sustainability benefits of purchasing second-hand goods should be included in general consumer information, and arguments for changes in behavior should be targeted to different groups of consumers. Keywords: online marketplaces; online auctions; consumer; electronic commerce; used products; second-hand market; sustainable consumptio

Perceived Impact of Contemporary Library technology on Academic Performance of Distance Education Undergraduates of Universities in Nigeria

The study looked at the impact of library technology on the academic performance of Nigerian university distance education undergraduates. A descriptive survey design was used in this investigation. The study was based on two research topics. The survey included 698 participants from Nigeria\u27s recognized universities. Because the study\u27s population size can be controlled, there was no need for sampling. The data collection instrument was a 39-item structured questionnaire produced by the researchers titled: Library technology on Academic Performance of Distance Education Questionnaire (TAPDEQ). Three specialists from the University of Nigeria, Nsukka\u27s Faculty of Education verified the instrument. The instrument\u27s internal consistency was determined using Cronbach Alpha for reliability analysis, yielding a coefficient of 0.84. To address the study questions, the data was analyzed using mean and standard deviation. The study\u27s findings revealed that poor or slow internet connectivity, low ICT penetration, a lack of knowledge and skills in designing and delivering courses in electronic format, and a lack of training opportunities for undergraduates on each library technology tool used in teaching and learning are among the factors that hinder contemporary library technology\u27s impact on academic performance of distance education undergraduates in universities. The study\u27s findings also revealed the advantages of modern library technology on academic performance of distance education undergraduates in universities, such as the ability to monitor and support undergraduate activity, provide communication for facilitators and adult learners, protect data and allow for data recovery, improve communication with learning content, and promote active learning and authentic assessment, among other things. Based on the findings of the study, it was suggested, among other things, that a university environment be built in order to provide the benefits of distant education to all regions of the country, particularly to the most remote portions of the population

Spare Parts Planning for Offshore Wind Turbines Subject to Restrictive Maintenance Conditions

AbstractThe use of offshore wind energy is supposed to play a significant role in future energy supply. Because offshore wind farms will be built in greater water depths and distances to shore according to other already realized offshore projects, maintenance is far more influenced by different restrictive factors. Limited availability of vessels, dependency on meteorological surrounding conditions, such as wind speed and weave height, as well as a complex logistical process chain require adjustment of up to now implemented maintenance concepts. In this context ensuring a reliable and cost-effective supply of spare parts is of great importance. This paper describes an approach for spare parts planning by considering restrictions that exist in the field of offshore maintenance. The model developed is used to show how restrictive factors influence maintenance and operation costs and how spare parts supply processes can be adopted. Scenario analysis will be used to estimate time of preventive maintenance activities and to investigate stock out costs caused by the restrictive accessibility

Entscheidungsunterstützung des Marketing-Managements durch Marketingsinformationssysteme

Das Thema Entscheidungsunterstützung des Marketing-Managements durch Marke-tinginformationssysteme (MAIS) umfasst einerseits Grundlagen des Marketing-Managements und- Controllings sowie der Arten von Informationen und Informations-quellen. Andererseits geht es um den Begriff MAIS und seine unterschiedlichen Aus-prägungen. Das Gebiet der Entscheidungsunterstützung erstreckt sich über Bereiche wie das Customer Relationship Management (CRM), Data Warehousing (DWH), Ana-lysemöglichkeiten für Endanwender und andere Komponenten des Prozesskreislaufs der Entscheidungsfindung. Zwei Fallbeispiele zum Einsatz von MAIS dienen als Anre-gung und Beispiel für Diskussionen zum Thema MAIS in der Praxis
