    2015-11-01

    Full Text Available It is essential to regularly test the usability of a learning management system, in order to ensure a fast adoption by new users and rapidly shift the focus from the platform to the content and the learning experience. Quantitative testing yields the most reliable results due to the large number of data points acquired, but lacks the in-depth analysis of the qualitative research from a controlled testing setup. We are proposing in this paper an integrated usability testing tool, which can replace a certain type of laboratory testing, where the users’ actions on the real platform are measured and analyzed. We conducted tests with the tool and compared the results with a small scale laboratory test using the same scenarios. The results seem to confirm the proposed tool as a viable alternative to the laboratory test.

    Usability tests are conducted to gauge users’ experience with a system, preferably before it is released for real use, and thereby find any problems that prevent users from completing their tasks, slow them down, or otherwise degrade their user experience. Such tests are important to successful...... systems development, yet test procedures vary and the quality of test results is sometimes contested. While there is no single accepted procedure for usability specialists to follow when conducting usability tests, these tests normally involve users who think out loud while using a system and an evaluator...... who observes the users’ behavior and listens in on their thoughts. This common core of usability tests is illustrated in Figure 1. The possible variations include, for example, whether the users work individually or in pairs, whether the evaluator is in the room with the user or in an adjoining room...

    Full Text Available Usability is an attribute of any good product, just as its functionality. It refers mainly to the utility of a product for its indented users, as well as to its ease of use. And whilst a correct functionality is critical for the commercial success of any product, its value comes through the human needs that it fulfills, which is determined through various marketing research techniques. In parallel, the IT&C community has developed in the last two decades its own type of research, called usability testing, used mainly to evaluate interface ease of use and all usability problems associated with.software products. This article aims at finding the right place for usability testing and usability professionals in the marketing community, as well as drawing a wider picture, from a marketing research perspective, on one of the most popular topics in IT&C community for the benefit of marketing scholars and professionals.

  16. Why Citizen Science Without Usability Testing Will Underperform

    Science.gov (United States)

    Romano, C.; Gay, P.; Owens, R.; Burlea, G.

    2017-12-01

    Citizen science projects must undergo usability testing and optimization if they are to meet their stated goals. This presentation will include video of usability tests conducted upon citizen science websites. Usability testing is essential to the success of online interaction, however, citizen science projects have just begun to include this critical activity. Interaction standards in citizen science lag behind those of commercial interests, and published research on this topic is limited. Since online citizen science is by definition, an exchange of information, a clear understanding of how users experience an online project is essential to informed decision-making. Usability testing provides that insight. Usability testing collects data via direct observation of a person while she interacts with a digital product, such as a citizen science website. The test participant verbalizes her thoughts while using the website or application; the moderator follows the participant and captures quantitative measurement of the participant's confidence of success as she advances through the citizen science project. Over 15 years of usability testing, we have observed that users who do not report a consistent sense of progress are likely to abandon a website after as few as three unrewarding interactions. Since citizen science is also a voluntary activity, ensuring seamless interaction for users is mandatory. Usability studies conducted on citizen science websites demonstrate that project teams frequently underestimate a user's need for context and ease of use. Without usability testing, risks to online citizen science projects include high bounce rate (users leave the website without taking any action), abandonment (of the website, tutorials, registration), misunderstanding instructions (causing disorientation and erroneous conclusions), and ultimately, underperforming projects.

  17. Commercial versus in-situ usability testing of healthcare information systems: towards "public" usability testing in healthcare organizations.

    Science.gov (United States)

    Kushniruk, Andre W; Borycki, Elizabeth M; Kannry, Joseph

    2013-01-01

    The need for improved usability in healthcare IT has been widely recognized. In addition, methods from usability engineering, including usability testing and usability inspection have received greater attention. Many vendors of healthcare software are now employing usability testing methods in the design and development of their products. However, despite this, the usability of healthcare IT is still considered to be problematic and many healthcare organizations that have purchased systems that have been tested at vendor testing sites are still reporting a range of usability and safety issues. In this paper we explore the distinction between commercial usability testing (conducted at centralized vendor usability laboratories and limited beta test sites) and usability testing that is carried out locally within healthcare organizations that have purchased vendor systems and products (i.e. public "in-situ" usability testing). In this paper it will be argued that both types of testing (i.e. commercial vendor-based testing) and in-situ testing are needed to ensure system usability and safety.

    2009-04-01

    Skilled website developers value usability testing to assure user needs are met. When the target audience differs substantially from the developers, it becomes essential to tailor both design and evaluation methods. In this study, researchers carried out a multifaceted usability evaluation of a website (Healthy Texas) designed for Hispanic audiences with lower computer literacy and lower health literacy. METHODS INCLUDED: (1) heuristic evaluation by a usability engineer, (2) remote end-user testing using WebEx software; and (3) face-to-face testing in a community center where use of the website was likely. Researchers found standard usability testing methods needed to be modified to provide interpreters, increased flexibility for time on task, presence of a trusted intermediary such as a librarian, and accommodation for family members who accompanied participants. Participants offered recommendations for website redesign, including simplified language, engaging and relevant graphics, culturally relevant examples, and clear navigation. User-centered design is especially important when website developers are not representative of the target audience. Failure to conduct appropriate usability testing with a representative audience can substantially reduce use and value of the website. This thorough course of usability testing identified improvements that benefit all users but become crucial when trying to reach an underserved audience.

    Boothe, Chase; Strawderman, Lesley; Hosea, Ethan

    2013-11-01

    Inconsistencies among testing methods and results in previous research prompted this study that builds upon a systematic usability testing research framework to better understand how interface medium influences users' abilities to detect usability flaws in applications. Interface medium was tested to identify its effects on users' perceptions of usability and abilities to detect usability problems and severe usability problems. Results indicated that medium has no effect on users' abilities to detect usability problems or perceptions of usability. However, results did indicate an interaction between the medium and the tested application in which users were able to identify significantly more usability problems on a higher fidelity medium using a particular application. Results also indicated that as users' perceptions of an application's usability increases, the users are less able to detect usability problems in that application. Usability testing should begin early in the design process, even if low fidelity mediums will be used. Copyright © 2013 Elsevier Ltd and The Ergonomics Society. All rights reserved.

    In the world's biggest research project, the sick building syndrome was investigated in Germany between 1995 and 1999. In all, 8 air-conditioned buildings and 6 non-air-conditioned buildings, 40 space HVAC systems and 1497 places of work were analyzed, and 4,500 persons were asked to provide data. For the first time ever, measured physical, biological and chemical data were compared with the subjective data provided by the inquiry forms. It was found that the concentrations and hygienic status of air conditioning systems do have an effect on subjective comfort. Buildings with well-designed and well-serviced space HVAC systems had better results than buildings without air conditioning systems. However, it is the psychosocial environment and the job description of building inhabitants that decide their response in terms of sick building syndrome. Factors like gender, job satisfaction, job specifications and educational level are more important than space HVAC systems. [German] Im Rahmen eines der weltweit groessten Forschungsprojekte zum Thema 'Sick Building Syndrome' wurden in Deutschland zwischen 1995 und 1999 umfangreiche Untersuchungen durchgefuehrt mit dem Ziel, die Ursachen und Folgen von Befindlichkeitsstoerungen in Buerogebaeuden zu ermitteln. Insgesamt wurden 8 klimatisierte und 6 nicht klimatisierte Gebaeude, 40 raumlufttechnische Anlagen und 1497 Arbeitsplaetze untersucht sowie ueber 4.500 Personen befragt. Die Ergebnisse erlauben zum ersten Mal einen direkten Vergleich der gemessenen physikalischen, biologischen und chemischen Werte mit den subjektiven Angaben (Fragebogendaten) an klimatisierten und nicht klimatisierten Arbeitsplaetzen. Die Auswertung zeigt, dass die Konzentration der Anlagen und deren hygienischer Wartungszustand einen Einfluss auf die Befindlichkeit der Mitarbeiter haben.

    Usability methods, such as heuristic evaluation, cognitive walk-throughs and user testing, are increasingly used to evaluate and improve the design of clinical software applications. There is still some uncertainty, however, as to how those methods can be used to support the development process and evaluation in the most meaningful manner. In this study, we compared the results of a heuristic evaluation with those of formal user tests in order to determine which usability problems were detected by both methods. We conducted heuristic evaluation and usability testing on four major commercial dental computer-based patient records (CPRs), which together cover 80% of the market for chairside computer systems among general dentists. Both methods yielded strong evidence that the dental CPRs have significant usability problems. An average of 50% of empirically-determined usability problems were identified by the preceding heuristic evaluation. Some statements of heuristic violations were specific enough to precisely identify the actual usability problem that study participants encountered. Other violations were less specific, but still manifested themselves in usability problems and poor task outcomes. In this study, heuristic evaluation identified a significant portion of problems found during usability testing. While we make no assumptions about the generalizability of the results to other domains and software systems, heuristic evaluation may, under certain circumstances, be a useful tool to determine design problems early in the development cycle.

  7. Integration of MSFC Usability Lab with Usability Testing

    Cheng, Yiwei; Richardson, Sally

    2010-01-01

    As part of the Stage Analysis Branch, human factors engineering plays an important role in relating humans to the systems of hardware and structure designs of the new launch vehicle. While many branches are involved in the technical aspects of creating a launch vehicle, human factors connects humans to the scientific systems with the goal of improving operational performance and safety while reducing operational error and damage to the hardware. Human factors engineers use physical and computerized models to visualize possible areas for improvements to ensure human accessibility to components requiring maintenance and that the necessary maintenance activities can be accomplished with minimal risks to human and hardware. Many methods of testing are used to fulfill this goal, such as physical mockups, computerized visualization, and usability testing. In this analysis, a usability test is conducted to test how usable a website is to users who are and are not familiar with it. The testing is performed using participants and Morae software to record and analyze the results. This analysis will be a preliminary test of the usability lab in preparation for use in new spacecraft programs, NASA Enterprise, or other NASA websites. The usability lab project is divided into two parts: integration of the usability lab and a preliminary test of the usability lab.

    Directory of Open Access Journals (Sweden)

    Sung Heum Lee

    1999-04-01

    Full Text Available Usability testing is a dynamic process that can be used throughout the process of developing interactive multimedia software. The purpose of usability testing is to find problems and make recommendations to improve the utility of a product during its design and development. For developing effective interactive multimedia software, dimensions of usability testing were classified into the general categories of: learnability; performance effectiveness; flexibility; error tolerance and system integrity; and user satisfaction. In the process of usability testing, evaluation experts consider the nature of users and tasks, tradeoffs supported by the iterative design paradigm, and real world constraints to effectively evaluate and improve interactive multimedia software. Different methods address different purposes and involve a combination of user and usability testing, however, usability practitioners follow the seven general procedures of usability testing for effective multimedia development. As the knowledge about usability testing grows, evaluation experts will be able to choose more effective and efficient methods and techniques that are appropriate to their goals.

  10. A Comparison of What Is Part of Usability Testing in Three Countries

    Science.gov (United States)

    Clemmensen, Torkil

    The cultural diversity of users of technology challenges our methods for usability evaluation. In this paper we report and compare three ethnographic interview studies of what is a part of a standard (typical) usability test in a company in Mumbai, Beijing and Copenhagen. At each of these three locations, we use structural and contrast questions do a taxonomic and paradigm analysis of a how a company performs a usability test. We find similar parts across the three locations. We also find different results for each location. In Mumbai, most parts of the usability test are not related to the interactive application that is tested, but to differences in user characteristics, test preparation, method, and location. In Copenhagen, considerations about the client's needs are part of a usability test. In Beijing, the only varying factor is the communication pattern and relation to the user. These results are then contrasted in a cross cultural matrix to identify cultural themes that can help interpret results from existing laboratory research in usability test methods.

    Full Text Available Open Educational Resources (OER are increasingly used in the higher education landscape as a solution for a variety of copyright, publishing and cost-prohibiting issues. While OERs are becoming more common, reports of usability tests that evaluate how well learners can use them to accomplish their learning tasks have lagged behind. Because both the researchers and the learners in this study use resources and tools remotely, asynchronous usability testing of a prototype OER and MOOC online guide was conducted with an exploratory group of users to determine the guide’s ease of use for two distinct groups of users: Educators and Learners. In this article, we share the background and context of this usability project, suggest best methods for asynchronous remote usability testing, and share challenges and insights of the process and results of the testing

    The idea of conducting usability tests remotely emerged ten years ago. Since then, it has been studied empirically, and some software organizations employ remote methods. Yet there are still few comparisons involving more than one remote method. This paper presents results from a systematic...... empirical comparison of three methods for remote usability testing and a conventional laboratorybased think-aloud method. The three remote methods are a remote synchronous condition, where testing is conducted in real time but the test monitor is separated spatially from the test subjects, and two remote...... asynchronous conditions, where the test monitor and the test subjects are separated both spatially and temporally....

    We seek to develop a prototype software analytical tool to augment FDA regulatory reviewers' capacity to harness scientific literature reports in PubMed/MEDLINE for pharmacovigilance and adverse drug event (ADE) safety signal detection. We also aim to gather feedback through usability testing to assess design, performance, and user satisfaction with the tool. A prototype, open source, web-based, software analytical tool generated statistical disproportionality data mining signal scores and dynamic visual analytics for ADE safety signal detection and management. We leveraged Medical Subject Heading (MeSH) indexing terms assigned to published citations in PubMed/MEDLINE to generate candidate drug-adverse event pairs for quantitative data mining. Six FDA regulatory reviewers participated in usability testing by employing the tool as part of their ongoing real-life pharmacovigilance activities to provide subjective feedback on its practical impact, added value, and fitness for use. All usability test participants cited the tool's ease of learning, ease of use, and generation of quantitative ADE safety signals, some of which corresponded to known established adverse drug reactions. Potential concerns included the comparability of the tool's automated literature search relative to a manual 'all fields' PubMed search, missing drugs and adverse event terms, interpretation of signal scores, and integration with existing computer-based analytical tools. Usability testing demonstrated that this novel tool can automate the detection of ADE safety signals from published literature reports. Various mitigation strategies are described to foster improvements in design, productivity, and end user satisfaction.

    Collaborative virtual reality-based systems have integrated high fidelity voice-based communication, immersive audio and screen-sharing tools into virtual environments. Such three-dimensional collaborative virtual environments can mirror the collaboration among usability test participants and facilitators when they are physically collocated, potentially enabling moderated usability tests to be conducted effectively when the facilitator and participant are located in different places. We developed a virtual collaborative three-dimensional remote moderated usability testing laboratory and employed it in a controlled study to evaluate the effectiveness of moderated usability testing in a collaborative virtual reality-based environment with two other moderated usability testing methods: the traditional lab approach and Cisco WebEx, a web-based conferencing and screen sharing approach. Using a mixed methods experimental design, 36 test participants and 12 test facilitators were asked to complete representative tasks on a simulated online shopping website. The dependent variables included the time taken to complete the tasks; the usability defects identified and their severity; and the subjective ratings on the workload index, presence and satisfaction questionnaires. Remote moderated usability testing methodology using a collaborative virtual reality system performed similarly in terms of the total number of defects identified, the number of high severity defects identified and the time taken to complete the tasks with the other two methodologies. The overall workload experienced by the test participants and facilitators was the least with the traditional lab condition. No significant differences were identified for the workload experienced with the virtual reality and the WebEx conditions. However, test participants experienced greater involvement and a more immersive experience in the virtual environment than in the WebEx condition. The ratings for the virtual

    Screening, brief intervention, and referral to treatment (SBIRT) is currently being implemented into health systems nationally via paper and electronic methods. The purpose of this study was to evaluate the integration of an electronic SBIRT tool into an existing paper-based SBIRT clinical workflow in a patient-centered medical home. Usability testing was conducted in an academic ambulatory clinic. Two rounds of usability testing were done with medical office assistants (MOAs) using a paper and electronic version of the SBIRT tool, with two and four participants, respectively. Qualitative and quantitative data was analyzed to determine the impact of both tools on clinical workflow. A second round of usability testing was done with the revised electronic version and compared with the first version. Personal workflow barriers cited in the first round of testing were that the electronic health record (EHR) tool was disruptive to patient's visits. In Round 2 of testing, MOAs reported favoring the electronic version due to improved layout and the inclusion of an alert system embedded in the EHR. For example, using the system usability scale (SUS), MOAs reported a grade "1" for the statement, "I would like to use this system frequently" during the first round of testing but a "5" during the second round of analysis. The importance of testing usability of various mediums of tools used in health care screening is highlighted by the findings of this study. In the first round of testing, the electronic tool was reported as less user friendly, being difficult to navigate, and time consuming. Many issues faced in the first generation of the tool were improved in the second generation after usability was evaluated. This study demonstrates how usability testing of an electronic SBRIT tool can help to identify challenges that can impact clinical workflow. However, a limitation of this study was the small sample size of MOAs that participated. The results may have been biased to

    Full Text Available Learning media is one of the important elements in the learning process. Technological development support makes learning media more varied. The approach of using digital technology as a learning media has a better and more effective impact than other approaches. In order to increase the students’ learning interest, it requires the support of an interesting learning media. The use of gaming applications as learning media can improve learning outcomes. The benefits of using the maximum application cannot be separated from the determination of application design. The Bana game aims to increase the ability of critical thinking of the junior high school students. The usability-testing analysis on the Bana game application is used in order to get the design reference as an educational game development. The game is used as an object of the analysis because it has the same characteristics and goals with the game application to be developed. Usability Testing is a method used to measure the ease of use of an application by users. The Usability Testing consists of learnability, efficiency, memorability, errors, and satisfaction. The results of the analysis obtained will be used as a reference for educational game applications that will be developed.

    Full Text Available The System Usability Scale, or SUS, was created in 1986 by John Brooke and has been used extensively by a variety of industries to test numerous applications and systems. The SUS is a technology agnostic tool consisting of ten questions with five responses for each question ranging from “strongly agree” to “strongly disagree.” Incorporating the SUS into library website and system usability testing may offer several benefits worth considering, however, it does have some very specific limitations and implementation challenges. This article summarizes examples in library and general literature of how the SUS has been incorporated into usability testing for websites, discovery tools, medical technologies, and print materials. Benefits and challenges of the SUS, best practices for incorporating the SUS into usability testing, and grading complexities are also examined. Possible alternatives and supplementary tools, such as single-item scales or other evaluative frameworks such as the UMUX, UMUX-LITE or SUPR-Q, are also briefly discussed.

    Rigorous usability testing of e-learn-ing resources is an important prerequisite to their wide-spread use among clinicians. This study demonstrates the application of an evidence-based approach to usability testing of two stroke-related e-learning resources (StrokEngine). 14 stroke rehabilitation clinicians (occupational therapists and physiotherapists) from Ontario, Canada participated in a 1.5 h in-person testing session. Clinicians navigated StrokEngine in search of information to answer questions on stroke assessment/intervention. Their search patterns were observed and clinicians provided verbal/written feedback about StrokEngine. Content analysis was used to generate themes and categorize them under two broad categories: facilitators and barriers to use. Five key facilitators and three key barriers to Strok-Engine use were identified and related to screen format, layout/organization, ease of navigation, quality of content, likelihood of using StrokEngine in the future, and system dysfunctions. All 14 clinicians were very or extremely satisfied with the layout/organization, quality and clinical relevance of the content, stating that they were likely to use StrokEngine in the future. All identified barriers from this study were addressed with website modifications in order to maximize the usability and navigability of StrokEngine. This rigorous methodology for usability testing can be applied during the design process of any e-learning resource.

    In recent years there has been considerable discussion around the need for certification and regulation of healthcare information technology (IT). In particular, the usability of the products being developed needs to be evaluated. This has included the application of standards designed to ensure the process of system development is user-centered and takes usability into consideration while a product is being developed. In addition to this, in healthcare, organizations in the United States and Europe have also addressed the need and requirement for product certification. However, despite these efforts there are continued reports of unusable and unsafe implementations. In this paper we discuss the need to not only include (and require) usability testing in the one-time development process of health IT products (such as EHRs), but we also argue for the need to additionally develop specific usability standards and requirements for usability testing during the implementation of vendor products (i.e. post product development) in healthcare settings. It is further argued that health IT products that may have been certified regarding their development process will still require application of usability testing in the process of implementing them in real hospital settings in order to ensure usability and safety. This is needed in order to ensure that the final result of both product development and implementation processes take into account and apply the latest usability principles and methods.

    Full Text Available Usability testing is a key step in the successful design of new technologies and tools, ensuring that heterogeneous populations will be able to interact easily with innovative applications. While usability testing methods of productivity tools (e.g., text editors, spreadsheets, or management tools are varied, widely available, and valuable, analyzing the usability of games, especially educational “serious” games, presents unique usability challenges. Because games are fundamentally different than general productivity tools, “traditional” usability instruments valid for productivity applications may fall short when used for serious games. In this work we present a methodology especially designed to facilitate usability testing for serious games, taking into account the specific needs of such applications and resulting in a systematically produced list of suggested improvements from large amounts of recorded gameplay data. This methodology was applied to a case study for a medical educational game, MasterMed, intended to improve patients’ medication knowledge. We present the results from this methodology applied to MasterMed and a summary of the central lessons learned that are likely useful for researchers who aim to tune and improve their own serious games before releasing them for the general public.

    Research in the fields of human performance technology and human computer interaction are challenging the traditional macro focus of usability testing arguing for methods that help test moderators assess "use in context" (ie, cognitive skills, usability understood over time) and in authentic "real world" settings. Human factors in these complex test scenarios may impact on the quality of usability results being derived yet there is a lack of research detailing moderator experiences in these test environments. Most comparative research has focused on the impact of the physical environment on results, and rarely on how the sociotechnical elements of the test environment affect moderator and test user performance. Improving our understanding of moderator roles and experiences with conducting "real world" usability testing can lead to improved techniques and strategies To understand moderator experiences of using Web-conferencing software to conduct remote usability testing of 2 eHealth interventions. An exploratory case study approach was used to study 4 moderators' experiences using Blackboard Collaborate for remote testing sessions of 2 different eHealth interventions. Data collection involved audio-recording iterative cycles of test sessions, collecting summary notes taken by moderators, and conducting 2 90-minute focus groups via teleconference. A direct content analysis with an inductive coding approach was used to explore personal accounts, assess the credibility of data interpretation, and generate consensus on the thematic structure of the results. Following the convergence of data from the various sources, 3 major themes were identified: (1) moderators experienced and adapted to unpredictable changes in cognitive load during testing; (2) moderators experienced challenges in creating and sustaining social presence and untangling dialogue; and (3) moderators experienced diverse technical demands, but were able to collaboratively troubleshoot with test users

    As the electronic health record (EHR) becomes the preferred documentation tool across medical practices, health care organizations are pushing for clinical decision support systems (CDSS) to help bring clinical decision support (CDS) tools to the forefront of patient-physician interactions. A CDSS is integrated into the EHR and allows physicians to easily utilize CDS tools. However, often CDSS are integrated into the EHR without an initial phase of usability testing, resulting in poor adoption rates. Usability testing is important because it evaluates a CDSS by testing it on actual users. This paper outlines the usability phase of a study, which will test the impact of integration of the Wells CDSS for pulmonary embolism (PE) diagnosis into a large urban emergency department, where workflow is often chaotic and high stakes decisions are frequently made. We hypothesize that conducting usability testing prior to integration of the Wells score into an emergency room EHR will result in increased adoption rates by physicians. The objective of the study was to conduct usability testing for the integration of the Wells clinical prediction rule into a tertiary care center's emergency department EHR. We conducted usability testing of a CDS tool in the emergency department EHR. The CDS tool consisted of the Wells rule for PE in the form of a calculator and was triggered off computed tomography (CT) orders or patients' chief complaint. The study was conducted at a tertiary hospital in Queens, New York. There were seven residents that were recruited and participated in two phases of usability testing. The usability testing employed a "think aloud" method and "near-live" clinical simulation, where care providers interacted with standardized patients enacting a clinical scenario. Both phases were audiotaped, video-taped, and had screen-capture software activated for onscreen recordings. Phase I: Data from the "think-aloud" phase of the study showed an overall positive outlook on

    The android based application “Jogja Smart Tourism (JST)” is designed to help everyone who visited Yogyakarta to enjoy their travel. As new application, it is need to be tested for its usability before launched. Usability testing will show how easy user interfaces are to used. The objective of this research is to demonstrate the result of usability testing for application JST based on five characteristics: learnability, effectiveness, memorability, errors, and satisfaction. About 30 respondents were involved to test the usability of this application. Learnability and effectiveness is calculated from some task that should be finished by respondents, and the rest aspects are calculated from questionnaires that should be answered after simulation. There are 14 functions bound in this usability testing. The result shows total usability level is in 81.75%. Learnability testing shows that 98.8% of respondent could finish the task successfully with 87.5% in efficiency. The memorability level of respondents is good (84.5%) where their ability to fix the errors is 71.5%. And the last for satisfaction level of application interface is 66.25%. Low level of satisfaction occurred because most of respondent felt uncomfortable with landscape interface of application because they should turn their mobile phone while using JST application and also it happened because the lack of using picture and colour inside the application. Both of these becomes important note for the improvement of further applications where the interface in a portrait version is more comfort the use and also utilization of colour and the image will be the main focus to improve customer satisfaction.

    This report describes the usability testing that has been done for the control and data acquisition system for the Light Duty Utility Arm (LDUA) System. A program of usability testing has been established as a part of a process for making the LDUA as easy to use as possible. The LDUA System is being designed to deploy a family of tools, called End Effectors, into underground storage tanks by means of a robotic arm on the end of a telescoping mast, and to collect and manage the data that they generate. The LDUA System uses a vertical positioning mast, to lower the arm into a tank through an existing 30.5 cm access riser. A Mobile Deployment Subsystem is used to position the mast and arm over a tank riser for deployment, and to transport them from tank to tank. The LDUA System has many ancillary subsystems including the Operations Control Trailer, the Tank Riser Interface and Confinement Subsystem, the Decontamination Subsystem, and the End Effector Exchange Subsystem. This work resulted in the identification of several important improvements to the LDUA control and data acquisition system before the design was frozen. The most important of these were color coding of joints in motion, simultaneous operator control of multiple joints, and changes to the field-of-views of the camera lenses for the robot and other camera systems

    2013-05-01

    This article examines the influence of socio-cultural background and product value on different outcomes of usability tests. A study was conducted in two different socio-cultural regions, Switzerland and East Germany, which differed in a number of aspects (e.g. economic power, price sensitivity and culture). Product value (high vs. low) was varied by manipulating the price of the product. Sixty-four test participants were asked to carry out five typical user tasks in the context of coffee machine usage, measuring performance, perceived usability, and emotion. The results showed that in Switzerland, high-value products were rated higher in usability than low-value products whereas in East Germany, high-value products were evaluated lower in usability. A similar interaction effect of socio-cultural background and product value was observed for user emotion. Implications are that the outcomes of usability tests do not allow for a simple transfer across cultures and that the mediating influence of perceived product value needs to be taken into consideration.

    Duplicate medical record creation is a common and consequential health care systems error often caused by poor search system usability and inappropriate user training. We conducted two phases of scenario-based usability testing with patient registrars working in areas at risk of generating duplicate medical records. Phase 1 evaluated the existing search system, which led to system redesigns. Phase 2 tested the redesigned system to mitigate potential errors before health system-wide implementation. To evaluate system effectiveness, we compared the monthly potential duplicate medical record rates for preimplementation and postimplementation months. The existing system could not effectively handle a misspelling, which led to failed search and duplicate medical record creation. Using the existing system, 96% of registrars found commonly spelled patient names whereas only 69% successfully found complicated names. Registrars lacked knowledge and usage of a phonetic matching function to assist in misspelling. The new system consistently captured the correct patient regardless of misspelling, but search returned more potential matches, resulting in, on average, 4 seconds longer to select common names. Potential monthly duplicate medical record rate reduced by 38%, from 4% to 2.3% after implementation of the new system, and has sustained at an average of 2.5% for 2 years. Usability testing was an effective method to reveal problems and aid system redesign to deliver a more user friendly system, hence reducing the potential for medical record duplication. Greater standards for usability would ensure that these improvements can be realized before rather than after exposing patients to risks.

    Objective Parents make the decisions regarding their children’s health care. Unfortunately, many parents are misinformed about HPV and HPV vaccines. In order to help parents make an informed decision regarding HPV vaccination for their daughter, the GoHealthyGirls website was created for parents and their adolescent daughters. Usability testing was conducted with members of the target population to refine the website prior to conducting an efficacy trial. Methods Parents with girls (n=9) between the ages of 11-13 and 11-13 year old adolescents (n=10) were recruited for usability testing. The testing consisted of completing twelve scenarios where participants were asked to find specific information on the GoHealthyGirls site. This was followed by a self-administered system usability scale—to determine ease of use and functionality of the website—and a user satisfaction survey. Results Both adult and adolescent participants were able to easily find the requested information and reported an increased positive opinion of HPV vaccines after visiting the website. Both groups of participants reported favorable evaluations of using the website. Conclusion The GoHealthyGirls website has the potential to help parents of adolescent daughters make an informed decision about HPV vaccination. A large scale efficacy trial will determine its usefulness. PMID:26594313

    Purpose: As a quality improvement measure, we undertook this work to incorporate usability testing into the implementation procedures for new electronic documents and forms used by four affiliated radiation therapy centers. Methods: A human factors specialist provided training in usability testing for a team of medical physicists, radiation therapists, and radiation oncologists from four radiotherapy centers. A usability testing plan was then developed that included controlled scenarios and standardized forms for qualitative and quantitative feedback from participants, including patients. Usability tests were performed by end users using the same hardware and viewing conditions that are found in the clinical environment. A pilot test of a form used during radiotherapy CT simulation was performed in a single department; feedback informed adaptive improvements to the electronic form, hardware requirements, resource accessibility and the usability testing plan. Following refinements to the testing plan, usability testing was performed at three affiliated cancer centers with different vault layouts and hardware. Results: Feedback from the testing resulted in the detection of 6 critical errors (omissions and inability to complete task without assistance), 6 non-critical errors (recoverable), and multiple suggestions for improvement. Usability problems with room layout were detected at one center and problems with hardware were detected at one center. Upon amalgamation and summary of the results, three key recommendations were presented to the document’s authors for incorporation into the electronic form. Documented inefficiencies and patient safety concerns related to the room layout and hardware were presented to administration along with a request for funding to purchase upgraded hardware and accessories to allow a more efficient workflow within the simulator vault. Conclusion: By including usability testing as part of the process when introducing any new document

    Decision aids are evidence-based tools designed to inform people of the potential benefit and harm of treatment options, clarify their preferences and provide a shared decision-making structure for discussion at a clinic visit. For patients with rheumatoid arthritis (RA) who are considering methotrexate, we have developed a web-based patient decision aid called the ANSWER (Animated, Self-serve, Web-based Research Tool). This study aimed to: 1) assess the usability of the ANSWER prototype; 2) identify strengths and limitations of the ANSWER from the patient's perspective. The ANSWER prototype consisted of: 1) six animated patient stories and narrated information on the evidence of methotrexate for RA; 2) interactive questionnaires to clarify patients' treatment preferences. Eligible participants for the usability test were patients with RA who had been prescribed methotrexate. They were asked to verbalize their thoughts (i.e., think aloud) while using the ANSWER, and to complete the System Usability Scale (SUS) to assess overall usability (range = 0-100; higher = more user friendly). Participants were audiotaped and observed, and field notes were taken. The testing continued until no new modifiable issues were found. We used descriptive statistics to summarize participant characteristics and the SUS scores. Content analysis was used to identified usability issues and navigation problems. 15 patients participated in the usability testing. The majority were aged 50 or over and were university/college graduates (n = 8, 53.4%). On average they took 56 minutes (SD = 34.8) to complete the tool. The mean SUS score was 81.2 (SD = 13.5). Content analysis of audiotapes and field notes revealed four categories of modifiable usability issues: 1) information delivery (i.e., clarity of the information and presentation style); 2) navigation control (i.e., difficulties in recognizing and using the navigation control buttons); 3) layout (i.e., position of the

    Low provider adoption continues to be a significant barrier to realizing the potential of clinical decision support. "Think Aloud" and "Near Live" usability testing were conducted on two clinical decision support tools. Each was composed of an alert, a clinical prediction rule which estimated risk of either group A Streptococcus pharyngitis or pneumonia and an automatic order set based on risk. The objective of this study was to further understanding of the facilitators of usability and to evaluate the types of additional information gained from proceeding to "Near Live" testing after completing "Think Aloud". This was a qualitative observational study conducted at a large academic health care system with 12 primary care providers. During "Think Aloud" testing, participants were provided with written clinical scenarios and asked to verbalize their thought process while interacting with the tool. During "Near Live" testing participants interacted with a mock patient. Morae usability software was used to record full screen capture and audio during every session. Participant comments were placed into coding categories and analyzed for generalizable themes. Themes were compared across usability methods. "Think Aloud" and "Near Live" usability testing generated similar themes under the coding categories visibility, workflow, content, understand-ability and navigation. However, they generated significantly different themes under the coding categories usability, practical usefulness and medical usefulness. During both types of testing participants found the tool easier to use when important text was distinct in its appearance, alerts were passive and appropriately timed, content was up to date, language was clear and simple, and each component of the tool included obvious indicators of next steps. Participant comments reflected higher expectations for usability and usefulness during "Near Live" testing. For example, visit aids, such as automatically generated order sets

    Full Text Available Usability testing is a very important step in improving App design and development. The traditional usability testing methods are based on users'expressions and behaviors, which hardly show users' emotional experience and cognitive load in real time. The introduction of an electrophysiological technique can make up for the deficiency of the traditional usability testing methods. In this study, a usability testing was carried out with the old and the new version of an App software. The behavior and the subjective evaluation of the participants were recorded, and their GSR and ECG signals were collected. Then, 14 physiological characteristics, such as GSR-Mean, LF, HF, LF/HF, etc., were extracted from the GSR and ECG signals. These characteristics were analyzed, and a significance test of difference of the two versions was made. This research indicated that there is a certain application value of GSR and HRV in usability testing and evaluation of an App product. But the meanings of the physiological characteristics must be explained in combination with the behavior and subjective evaluation of users. The result can prove that physiological characteristics have obvious advantages in real-time monitoring users' emotional changes, which can be helpful to find the usability problems of the product.

    accessibility evaluations and guidelines in many countries. WCAG version 2.0 was released in 2008. This paper reports on a study that empirically validated the usefulness of using WCAG as a heuristic for website accessibility. Through controlled usability tests of two websites with disabled users (N = 7......) and a control group (N = 6), it was found that only 27% of the identified website accessibility problems could have been identified through the use of WCAG 1.0. A similar analysis of conformance to WCAG 2.0 showed a marginal 5% improvement concerning identified website accessibility problems. Compensating...... for the low number of test subjects with confidence tests gave results that were still low (42% for WCAG 1.0 and 49% for WCAG 2.0, with 95% confidence). It is concluded from this that the application of WAI accessibility guidelines is not sufficient to guarantee website accessibility. It is recommended...

    Usability moderators found that the concurrent think-aloud (CTA) method has some cultural limitation that impacts usability testing with Malaysian users. This gives rise to proposing a new method called textual feedback. The research question is to determine whether there are any differences...... in terms of usability defects found by employing the new method. Due to the high power distance, it is hypothesized that the CTA method may not be sufficient and hence a textual feedback method is recommended instead. Hence, the objective of this study is to determine if there are any differences...... in usability defects from the concurrent think-aloud (CTA) method (Condition 2) and textual feedback method (Condition 1) within the same group of Malaysian users.

    2016-11-01

    As competition for specialty clinical placements increases, there is an urgent need to create safe, stimulating, alternative learning environments for students. To address that clinical gap, our team developed a virtual game-based simulation to help nursing students develop their pediatric nursing skills. A usability study was conducted using the Technology Acceptance Model as a research framework. The study was conducted at a community college and included nursing students, nursing faculty/clinicians and two gaming experts. The two experts evaluated the game using a heuristic checklist after playing the game. Participants engaged in a think-aloud activity while playing the game and completed a survey and interview based on the Technology Acceptance Model to explore ease of use and utility of the game. We found a high degree of user satisfaction with the game. Students reported that they had learned about pediatric care, they had become immersed in the game and they were keen to keep playing. Several design changes were recommended. Usability testing is critical in the early stages of simulation development and the study provided useful direction for the development team in the next stage of game development.

    Full Text Available Discovery tools are emerging in libraries. These tools offer library patrons the ability to concurrently search the library catalog and journal articles. While vendors rush to provide feature-rich interfaces and access to as much content as possible, librarians wonder about the usefulness of these tools to library patrons. In order to learn about both the utility and usability of EBSCO Discovery Service, James Madison University conducted a usability test with eight students and two faculty members. The test consisted of nine tasks focused on common patron requests or related to the utility of specific discovery tool features. Software recorded participants’ actions and time on task, human observers judged the success of each task, and a post-survey questionnaire gathered qualitative feedback and comments from the participants.  Overall, participants were successful at most tasks, but specific usability problems suggested some interface changes for both EBSCO Discovery Service and JMU’s customizations of the tool.  The study also raised several questions for libraries above and beyond any specific discovery tool interface, including the scope and purpose of a discovery tool versus other library systems, working with the large result sets made possible by discovery tools, and navigation between the tool and other library services and resources.  This article will be of interest to those who are investigating discovery tools, selecting products, integrating discovery tools into a library web presence, or performing evaluations of similar systems.

    Currently, there are few resources for electronic health record (EHR) purchasers and end users to understand the usability processes employed by EHR vendors during product design and development. We developed a framework, based on human factors literature and industry standards, to systematically evaluate the user-centered design processes and usability testing methods used by EHR vendors. We reviewed current usability certification requirements and the human factors literature to develop a 15-point framework for evaluating EHR products. The framework is based on 3 dimensions: user-centered design process, summative testing methodology, and summative testing results. Two vendor usability reports were retrieved from the Office of the National Coordinator's Certified Health IT Product List and were evaluated using the framework. One vendor scored low on the framework (5 pts) while the other vendor scored high on the framework (15 pts). The 2 scored vendor reports demonstrate the framework's ability to discriminate between the variabilities in vendor processes and to determine which vendors are meeting best practices. The framework provides a method to more easily comprehend EHR vendors' usability processes and serves to highlight where EHR vendors may be falling short in terms of best practices. The framework provides a greater level of transparency for both purchasers and end users of EHRs. The framework highlights the need for clearer certification requirements and suggests that the authorized certification bodies that examine vendor usability reports may need to be provided with clearer guidance. © The Author 2016.

    Developed in Norway, Sisom is an interactive, rigorously tested, computerized, communication tool designed to help children with cancer express their perceived symptoms/problems. Children travel virtually from island to island rating their symptoms/problems. While Sisom has been found to significantly improve communication in patient consultations in Norway, usability testing is warranted with US children prior to further use in research studies. The objective of this study was to determine the usability of Sisom in a sample of English- and Spanish-speaking children in an urban US community. A mixed-methods usability study was conducted with a purposive sample of healthy children and children with cancer. Semistructured interviews were used to assess healthy children's symptom recognition. Children with cancer completed 8 usability tasks captured with Morae 3.3 software. Data were downloaded, transcribed, and analyzed descriptively. Four healthy children and 8 children with cancer participated. Of the 44 symptoms assessed, healthy children recognized 15 (34%) pictorial symptoms immediately or indicated 13 (30%) pictures were good representations of the symptom. Six children with cancer completed all tasks. All children navigated successfully from one island to the next, ranking their symptom/problem severity, clicking the magnifying glass for help, or asking the researcher for assistance. All children were satisfied with the aesthetics and expressed an interest in using Sisom to communicate their symptoms/problems. A few minor suggestions for improvement and adjustment may optimize the use of Sisom for US children. Sisom may help clinicians overcome challenges assessing children's complex symptoms/problems in a child-friendly manner.

    2015-01-01

    The development of more usable and effective healthcare information systems has become a critical issue. In the software industry methodologies such as agile and iterative development processes have emerged to lead to more effective and usable systems. These approaches highlight focusing on user needs and promoting iterative and flexible development practices. Evaluation and testing of iterative agile development cycles is considered an important part of the agile methodology and iterative processes for system design and re-design. However, the issue of how to effectively integrate usability testing methods into rapid and flexible agile design cycles has remained to be fully explored. In this paper we describe our application of an approach known as low-cost rapid usability testing as it has been applied within agile system development in healthcare. The advantages of the integrative approach are described, along with current methodological considerations.

    Clinical decision support systems (CDSSs) that are integrated into electronic medical records may be useful for encouraging practice change compliant with clinical practice guidelines. To engage end users to inform early phase CDSS development through a process of usability testing. A sequential exploratory mixed method approach was used. Interprofessional clinician participants (seven in iteration 1 and six in iteration 2) were asked to 'think aloud' while performing various tasks on the CDSS and then complete the System Usability Scale (SUS). Changes were made to the CDSS after each iteration.Results Barriers and facilitators were identified: systemic; user interface (most numerous barriers); content (most numerous facilitators) and technical. The mean SUS score was 81.1 (SD = 12.02) in iteration 1 and 70.40 (SD = 6.78) in iteration 2 (p > 0.05). Qualitative data from usability testing were valuable in the CDSS development process. SUS scores were of limited value at this development stage.

    As adolescents with hemophilia approach adulthood, they are expected to assume responsibility for their disease management. A bilingual (English and French) Internet-based self-management program, "Teens Taking Charge: Managing Hemophilia Online," was developed to support adolescents with hemophilia in this transition. This study explored the usability of the website and resulted in refinement of the prototype. A purposive sample (n=18; age 13-18; mean age 15.5 years) was recruited from two tertiary care centers to assess the usability of the program in English and French. Qualitative observations using a "think aloud" usability testing method and semi-structured interviews were conducted in four iterative cycles, with changes to the prototype made as necessary following each cycle. This study was approved by research ethics boards at each site. Teens responded positively to the content and appearance of the website and felt that it was easy to navigate and understand. The multimedia components (videos, animations, quizzes) were felt to enrich the experience. Changes to the presentation of content and the website user-interface were made after the first, second and third cycles of testing in English. Cycle four did not result in any further changes. Overall, teens found the website to be easy to use. Usability testing identified end-user concerns that informed improvements to the program. Usability testing is a crucial step in the development of Internet-based self-management programs to ensure information is delivered in a manner that is accessible and understood by users.

    The objective of this study was to conduct the first patient usability testing of a mobile health (mHealth) system for in-home swallowing therapy. Five participants with a history of head and neck cancer evaluated the mHealth system. After completing an in-application (app) tutorial with the clinician, participants were asked to independently complete five tasks: pair the device to the smartphone, place the device correctly, exercise, interpret progress displays, and close the system. Quantitative and qualitative methods were used to evaluate the effectiveness, efficiency, and satisfaction with the system. Critical changes to the app were found in three of the tasks, resulting in recommendations for the next iteration. These issues were related to ease of Bluetooth pairing, placement of device, and interpretation of statistics. Usability testing with patients identified issues that were essential to address prior to implementing the mHealth system in subsequent clinical trials. Of the usability methods used, video observation (synced screen capture with videoed gestures) revealed the most information.

    Various computerized health risk appraisals (HRAs) are available, but few of them assess health-related quality of life (HRQoL) in a goal-directed framework. This study describes the user-centered development and usability testing of an innovative HRQoL module that extends a validated HRA tool in primary care settings. Systematic user-centered design, usability testing, and qualitative methods were used to develop the HRQoL module in primary care practices. Twenty two patients and 5 clinicians participated in two rounds of interactive technology think-out-loud sessions (TOLs) and semi-structured interviews (SSIs) to iteratively develop a four-step, computerized process that collects information on patient goals for meaningful life activities and current level of disability and presents a personalized and prioritized list of preventive recommendations linked to online resources. Analysis of TOLs and SSIs generated 5 categories and 11 sub-categories related to facilitators and barriers to usability and human-technology interaction. The categories included: Understanding the Purpose, Usability, Perceived Value, Literacy, and Participant Motivation. Some categories were inter-connected. The technology was continually and iteratively improved between sessions until saturation of positive feedback was achieved in 4 categories (addressing motivation will require more research). Usability of all screen units of the module was improved substantially. Clinician feedback emphasized the importance of the module's ability to translate the patient-centered HRQoL Report into actionable items for clinicians to facilitate shared decision-making. Complete integration of the HRQoL module into the existing HRA will require further development and testing. Systematic application of user-centered design and human factors principles in technology development and testing may significantly improve the usability and clinical value of health information systems.

    The feasibility and acceptability of computerized screening and patient-reported outcome measures have been demonstrated in the literature. However, patient-centered management of health information entails two challenges: gathering and presenting data using "patient-tailored" methods and supporting "patient-control" of health information. The design and development of many symptom and quality-of-life information systems have not included opportunities for systematically collecting and analyzing user input. As part of a larger clinical trial, the Electronic Self-Report Assessment for Cancer-II project, participatory design approaches were used to build and test new features and interfaces for patient/caregiver users. The research questions centered on patient/caregiver preferences with regard to the following: (a) content, (b) user interface needs, (c) patient-oriented summary, and (d) patient-controlled sharing of information with family, caregivers, and clinicians. Mixed methods were used with an emphasis on qualitative approaches; focus groups and individual usability tests were the primary research methods. Focus group data were content analyzed, while individual usability sessions were assessed with both qualitative and quantitative methods. We identified 12 key patient/caregiver preferences through focus groups with 6 participants. We implemented seven of these preferences during the iterative design process. We deferred development for some of the preferences due to resource constraints. During individual usability testing (n = 8), we were able to identify 65 usability issues ranging from minor user confusion to critical errors that blocked task completion. The participatory development model that we used led to features and design revisions that were patient centered. We are currently evaluating new approaches for the application interface and for future research pathways. We encourage other researchers to adopt user-centered design approaches when building

    At this moment, the need for web as an information media is highly important. Not only confined in the infotainment area, government, and education, but health as well uses the web media as a medium for providing information effectively. BloobIS is a web based application which integrates blood supply and distribution information at the Blood Transfusion Unit. Knowing how easy information is on BloobIS is marked by how convenient the website is used. Up until now, the BloobIS website is nearing completion but testing has not yet been performed to users and is on the testing and development phase in the Development Life Cycle software. Thus, an evaluation namely the quality control software which focuses on the perspective of BloobIs web usability is required. Hallway Usability Testing and ISO 9241:11 are the methods chosen to measure the BloobIS application usability. The expected outputs of the quality control software focusing on the usability evaluation are being able to rectify the usability deficiencies on the BloobIs web and provide recommendations to develop the web as a basic BloobIS web quality upgraed which sets a goal to amplify the satisfaction of web users based on usability factors in ISO 9241:11.

Therefore, we conducted a narrative review of peer-reviewed articles published from 2009 to 2013 that tested the usability of a web- or mobile-delivered system/application designed to educate and support patients with diabetes. Overall, the 23 papers included in our review used mixed (n = 11), descriptive quantitative (n = 9), and qualitative methods (n = 3) to assess usability, such as documenting which features performed as intended and how patients rated their experiences. More sophisticated usability evaluations combined several complementary approaches to elucidate more aspects of functionality. Future work pertaining to the design and evaluation of technology-delivered diabetes education/support interventions should aim to standardize the usability testing processes and publish usability findings to inform interpretation of why an intervention succeeded or failed and for whom.

    Usability evaluations can improve the usability and workflow integration of clinical decision support (CDS). Traditional usability testing using scripted scenarios with think-aloud protocol analysis provide a useful but incomplete assessment of how new CDS tools interact with users and clinical workflow. "Near-live" clinical simulations are a newer usability evaluation tool that more closely mimics clinical workflow and that allows for a complementary evaluation of CDS usability as well as impact on workflow. This study employed two phases of testing a new CDS tool that embedded clinical prediction rules (an evidence-based medicine tool) into primary care workflow within a commercial electronic health record. Phase I applied usability testing involving "think-aloud" protocol analysis of 8 primary care providers encountering several scripted clinical scenarios. Phase II used "near-live" clinical simulations of 8 providers interacting with video clips of standardized trained patient actors enacting the clinical scenario. In both phases, all sessions were audiotaped and had screen-capture software activated for onscreen recordings. Transcripts were coded using qualitative analysis methods. In Phase I, the impact of the CDS on navigation and workflow were associated with the largest volume of negative comments (accounting for over 90% of user raised issues) while the overall usability and the content of the CDS were associated with the most positive comments. However, usability had a positive-to-negative comment ratio of only 0.93 reflecting mixed perceptions about the usability of the CDS. In Phase II, the duration of encounters with simulated patients was approximately 12 min with 71% of the clinical prediction rules being activated after half of the visit had already elapsed. Upon activation, providers accepted the CDS tool pathway 82% of times offered and completed all of its elements in 53% of all simulation cases. Only 12.2% of encounter time was spent using the

    Information and communication technology (ICT) has been used with increasing frequency for the assessment of diet and physical activity in health surveys. A number of Web-based questionnaires have been developed for children and adolescents. However, their usability characteristics have scarcely been reported, despite their potential importance for improving the feasibility and validity of ICT-based methods. The objective of this study was to describe the usability evaluation of the Consumo Alimentar e Atividade Física de Escolares (CAAFE) questionnaire (Food Consumption and Physical Activity Questionnaire for schoolchildren), a new Web-based survey tool for the self-assessment of diet and physical activity by schoolchildren. A total of 114 schoolchildren aged 6 to 12 years took part in questionnaire usability testing carried out in computer classrooms at five elementary schools in the city of Florianopolis, Brazil. Schoolchildren used a personal computer (PC) equipped with software for recording what is on the computer screen and the children's speech during usability testing. Quantitative and qualitative analyses took into account objective usability metrics such as error counts and time to complete a task. Data on the main difficulties in accomplishing the task and the level of satisfaction expressed by the children were assessed by the observers using a standardized form and interviews with the children. Descriptive statistics and content analysis were used to summarize both the quantitative and the qualitative aspects of the data obtained. The mean time for completing the questionnaire was 13.7 minutes (SD 3.68). Compared to the children in 2nd or 3rd grades, those in 4th or 5th grades spent less time completing the questionnaire (median 12.4 vs 13.3 minutes, P=.022), asked for help less frequently (median 0 vs 1.0 count, P=.005), had a lower error count (median 2.0 vs 8.0 count, P<.001), and obtained a higher overall performance score (median 73.0 vs 68.0, P

    Full Text Available A novel mobile health platform, Interactive Mobile Health and Rehabilitation (iMHere, is being developed to support wellness and self-management among people with chronic disabilities. The iMHere system currently includes a smartphone app with six modules for use by persons with disabilities and a web portal for use by medical and rehabilitation professionals or other support personnel. Our initial clinical research applying use of this system provides insight into the feasibility of employing iMHere in the development of self-management skills in young adults (ages 18-40 years with spina bifida (Dicianno, Fairman, McCue, Parmanto, Yih, et al., 2015. This article is focused on describing the iterative design of the iMHere system including usability testing of both the app modules and clinician portal. Our pilot population of persons with spina bifida fostered the creation of a system appropriate for people with a wide variety of functional abilities and needs. As a result, the system is appropriate for use by persons with various disabilities and chronic conditions, not only spina bifida. In addition, the diversity of professionals and support personnel involved in the care of persons with spina bifida (SB also enabled the design and implementation of the iMHere system to meet the needs of an interdisciplinary team of providers who treat various conditions. The iMHere system has the potential to foster communication and collaboration among members of an interdisciplinary healthcare team, including individuals with chronic conditions and disabilities, for client-centered approach to support self-management skills.

    This paper presents a novel application of an assistive robotic system with virtual assistance to enhance manual performance of individuals with cerebral palsy. Cerebral palsy affects one's voluntary motor movements resulting in limited opportunities to actively engage in physical manipulative activities that require fine motor movements and coordination. Lack of object manipulation and environmental exploration can result in further impairments such as cognitive and social delays. The proposed assistive robotic system has been developed to enhance hand movements of people with disabilities when performing a functional task colouring. This paper presents the usability testing of the effectiveness of the developed system with an individual with cerebral palsy in a set of colouring tasks. Assisted and unassisted approaches were compared and analysed through quantitative and qualitative measures. The robotic-based approach was further compared with the participant's typical alternate access method to perform the same proposed tasks. The robotic system with virtual assistance was clinically validated to be significantly more effective, compared to both unassisted and typical approaches, by increasing the hand controllability, reducing the physical load and increasing the easiness of maintaining movements within the lines. Future studies will inform the use of the system for children with disabilities to provide them with assisted play for functional and playful activities. Implications for rehabilitation Robotic system can enhance manual performance in individuals with disabilities. Participating in a robot-mediated play activity could increase children's motivation and engagement. The developed robotic system can contribute to a basis for clinical and home-based implementation of the technology to promote manual play activities for children with disabilities.

    Full Text Available RANK („Receptor Activator of NF-κB“ und sein Ligand RANKL sind Schlüsselmoleküle im Knochenmetabolismus und spielen eine essenzielle Rolle in der Entstehung von pathologischen Knochenveränderungen. Die Deregulation des RANK/RANKL-Systems ist zum Beispiel ein Hauptgrund für das Auftreten von postmenopausaler Osteoporose bei Frauen. Eine weitere wesentliche Funktion von RANK und RANKL liegt in der Entwicklung von milchsekretierenden Drüsen während der Schwangerschaft. Dabei regulieren Sexualhormone, wie zum Beispiel Progesteron, die Expression von RANKL und induzieren dadurch die Proliferation von epithelialen Zellen der Brust. Seit Längerem war schon bekannt, dass RANK und RANKL in der Metastasenbildung von Brustkrebszellen im Knochengewebe beteiligt sind. Wir konnten nun das RANK/RANKLSystem auch als essenziellen Mechanismus in der Entstehung von hormonellem Brustkrebs identifizieren. In diesem Beitrag werden wir daher den neuesten Erkenntnissen besondere Aufmerksamkeit schenken und diese kritisch in Bezug auf Brustkrebsentwicklung betrachten.

    The development of Web-based interventions for substance abuse in Latin America is a new field of interest with great potential for expansion to other Spanish-speaking countries. This paper describes a project aimed to develop and evaluate the usability of the Web-based Help Program for Drug Abuse and Depression (Programa de Ayuda para Abuso de Drogas y Depresión, PAADD, in Spanish) and also to construct a systematic frame of reference for the development of future Web-based programs. The PAADD aims to reduce substance use and depressive symptoms with cognitive behavioral techniques translated into Web applications, aided by the participation of a counselor to provide support and guidance. This Web-based intervention includes 4 steps: (1) My Starting Point, (2) Where Do I Want to Be? (3) Strategies for Change, and (4) Maintaining Change. The development of the program was an interactive multistage process. The first stage defined the core structure and contents, which were validated in stage 2 by a group of 8 experts in addiction treatment. Programming of the applications took place in stage 3, taking into account 3 types of end users: administrators, counselors, and substance users. Stage 4 consisted of functionality testing. In stage 5, a total of 9 health professionals and 20 drug users currently in treatment voluntarily interacted with the program in a usability test, providing feedback about adjustments needed to improve users' experience. The main finding of stage 2 was the consensus of the health professionals about the cognitive behavioral strategies and techniques included in PAADD being appropriate for changing substance use behaviors. In stage 5, the health professionals found the functionalities easy to learn; their suggestions were related to the page layout, inclusion of confirmation messages at the end of activities, avoiding "read more" links, and providing feedback about every activity. On the other hand, the users said the information presented

    To compare the performance of the Concurrent (CTA) and Retrospective (RTA) Think Aloud method and to assess their value in a formative usability evaluation of an Intensive Care Registry-physician data query tool designed to support ICU quality improvement processes. Sixteen representative intensive care physicians participated in the usability evaluation study. Subjects were allocated to either the CTA or RTA method by a matched randomized design. Each subject performed six usability-testing tasks of varying complexity in the query tool in a real-working context. Methods were compared with regard to number and type of problems detected. Verbal protocols of CTA and RTA were analyzed in depth to assess differences in verbal output. Standardized measures were applied to assess thoroughness in usability problem detection weighted per problem severity level and method overall effectiveness in detecting usability problems with regard to the time subjects spent per method. The usability evaluation of the data query tool revealed a total of 43 unique usability problems that the intensive care physicians encountered. CTA detected unique usability problems with regard to graphics/symbols, navigation issues, error messages, and the organization of information on the query tool's screens. RTA detected unique issues concerning system match with subjects' language and applied terminology. The in-depth verbal protocol analysis of CTA provided information on intensive care physicians' query design strategies. Overall, CTA performed significantly better than RTA in detecting usability problems. CTA usability problem detection effectiveness was 0.80 vs. 0.62 (pusability problems of a moderate (0.85 vs. 0.7) and severe nature (0.71 vs. 0.57). In this study, the CTA is more effective in usability-problem detection and provided clarification of intensive care physician query design strategies to inform redesign of the query tool. However, CTA does not outperform RTA. The RTA

    Pain assessment in older adults with cognitive impairment is often challenging, and paramedics are not given sufficient tools/training to assess pain. The development of a mobile app may improve pain assessment and management in this vulnerable population. We conducted usability testing of a newly developed iPhone pain assessment application with potential users, in this case as a tool for clinical paramedic practice to improve pain assessment of older adults with cognitive impairment. We conducted usability testing with paramedic students and a Delphi panel of qualified paramedics. Participants studied the app and paper-based algorithm from which the app was developed. The potential use for the app was discussed. Usability testing focus groups were recorded, transcribed verbatim, and analyzed using a thematic approach. Proposed recommendations were disseminated to the Delphi panel that reviewed and confirmed them. Twenty-four paramedic students from two UK ambulance services participated in the focus groups. Usability of the app and its potential were viewed positively. Four major themes were identified: 1) overall opinion of the app for use in paramedic services; 2) incorporating technological applications into the health care setting; 3) improving knowledge and governance; and 4) alternative uses for the app. Subthemes were identified and are presented. Our results indicate that the pain assessment app constitutes a potentially useful tool in the prehospital setting. By providing access to a tool specifically developed to help identify/assess pain in a user-friendly format, paramedics are likely to have increased knowledge and confidence in assessing pain in patients with dementia. © 2017 American Academy of Pain Medicine.

    In order to meet the need for accessible interventions and support for families affected by fetal alcohol spectrum disorder (FASD), we have developed an Internet-based, distance intervention for caregivers of children with FASD between the ages of four and twelve, called Strongest Families™ FASD. To evaluate the usability of the Strongest Families FASD program content and website in terms of learnability, efficiency and acceptability. A remote usability testing approach was conducted in two iterative cycles of participants. Synchronous online usability testing sessions were conducted, followed by asynchronous testing. A total of 18 participants were included, comprised of both health care professionals with expertise in FASD and caregivers of children with FASD. The data collected in each cycle was examined for commonalities and results were used to inform changes to the website and content after each cycle. Participants rated the website as appealing and relatively easy and fast to use. Nevertheless, several usability problems were identified such as difficulty navigating between sections of content on the website, displaying too much content per page, and the relevance and appropriateness of the content as it related to FASD. The identification of usability problems was an important step in refining the Strongest Families FASD program before its effectiveness is evaluated in a randomized controlled trial.

    Many new decision aids are developed while aspects of existing decision aids could also be useful, leading to a sub-optimal use of resources. To support treatment decision-making in prostate cancer patients, a pre-existing evidence-based Canadian decision aid was adjusted to Dutch clinical setting. After analyses of the original decision aid and routines in Dutch prostate cancer care, adjustments to the decision aid structure and content were made. Subsequent usability testing (N = 11) resulted in 212 comments. Care providers mainly provided feedback on medical content, and patients commented most on usability and summary layout. All participants reported that the decision aid was comprehensible and well-structured and would recommend decision aid use. After usability testing, final adjustments to the decision aid were made. The presented methods could be useful for cultural adaptation of pre-existing tools into other languages and settings, ensuring optimal usage of previous scientific and practical efforts and allowing for a global, incremental decision aid development process.

    Usability evaluation provides developers and educators with the means to understand user needs, improve overall product utility, and increase user satisfaction. The application of "discount usability" principles developed to make usability testing more practical and useful may improve user experience at minimal cost and require little existing expertise to conduct. We describe an application of discount usability to a high-fidelity online communications assessment application developed by the University of Washington for the American Board of Internal Medicine. Eight internal medicine physicians completed a discount usability test. Sessions were recorded and the videos analyzed for significant usability concerns. Concerns were identified, summarized, discussed, and prioritized by the authors in collaboration with the software developers before implementing any changes to the interface. Thirty-eight significant usability issues were detected and four technical problems were identified. Each issue was responded to through modification of the software, by providing additional instruction, or delayed for a later version to be developed. Discount usability can be easily implemented in academic developmental activities. Our study resulted in the discovery and remediation of significant user problems, in addition to giving important insight into the novel methods built into the application.

    Low health literacy has been associated with poor health-related outcomes. The purposes are to report the development of a website for low-literate parents in the Neonatal Intensive Care Unit (NICU), and the findings of heuristic evaluation and a usability testing of this website. To address low literacy of NICU parents, multimedia educational Website using visual aids (e.g., pictographs, photographs), voice-recorded text message in addition to a simplified text was developed. The text was created at the 5th grade readability level. The heuristic evaluation was conducted by three usability experts using 10 heuristics. End-users' performance was measured by counting the time spent completing tasks and number of errors, as well as recording users' perception of ease of use and usefulness (PEUU) in a sample of 10 NICU parents. Three evaluators identified 82 violations across the 10 heuristics. All violations, however, received scores Website as easy to use and useful (PEUU mean = 4.52, SD = 0.53). Based on the participants' comments, appropriate modifications were made. Different types of visuals on the Website were well accepted by low-literate users and agreement of visuals with text improved understanding of the educational materials over that with text alone. The findings suggest that using concrete and realistic pictures and pictographs with clear captions would maximize the benefit of visuals. One emerging theme was "simplicity" in design (e.g., limited use of colors, one font type and size), content (e.g., avoid lengthy text), and technical features (e.g., limited use of pop-ups). The heuristic evaluation by usability experts and the usability test with actual users provided complementary expertise, which can give a richer assessment of a design for low literacy Website. These results facilitated design modification and implementation of solutions by categorizing and prioritizing the usability problems.

    Virtual reality (VR) is not commonly used in clinical rehabilitation, and commercial VR gaming systems may have mixed effects in patients with stroke. Therefore, we developed RehabMaster™, a task-specific interactive game-based VR system for post-stroke rehabilitation of the upper extremities, and assessed its usability and clinical efficacy. A participatory design and usability tests were carried out for development of RehabMaster with representative user groups. Two clinical trials were then performed. The first was an observational study in which seven patients with chronic stroke received 30 minutes of RehabMaster intervention per day for two weeks. The second was a randomised controlled trial of 16 patients with acute or subacute stroke who received 10 sessions of conventional occupational therapy only (OT-only group) or conventional occupational therapy plus 20 minutes of RehabMaster intervention (RehabMaster + OT group). The Fugl-Meyer Assessment score (FMA), modified Barthel Index (MBI), adverse effects, and drop-out rate were recorded. The requirements of a VR system for stroke rehabilitation were established and incorporated into RehabMaster. The reported advantages from the usability tests were improved attention, the immersive flow experience, and individualised intervention. The first clinical trial showed that the RehabMaster intervention improved the FMA (P = .03) and MBI (P = .04) across evaluation times. The second trial revealed that the addition of RehabMaster intervention tended to enhance the improvement in the FMA (P = .07) but did not affect the improvement in the MBI. One patient with chronic stroke left the trial, and no adverse effects were reported. The RehabMaster is a feasible and safe VR system for enhancing upper extremity function in patients with stroke.

    Oral cancer (OC) survivors experience debilitating side effects that affect their quality of life (QOL) and that of their caregivers. This study aimed to develop and evaluate a dyadic, web-based intervention to improve survivor self-management and survivor/caregiver QOL. A qualitative needs assessment (semi-structured interviews) with 13 OC survivors and 12 caregivers was conducted to discern information and support needs as well as preferences regarding website features and tools. Results using Grounded Theory analysis showed that OC survivors and caregivers: (1) want and need practical advice about managing side effects; (2) want to reach out to other survivors/caregivers for information and support; and (3) have both overlapping and unique needs and preferences regarding website features. Usability testing (N = 6 survivors; 5 caregivers) uncovered problems with the intuitiveness, navigation and design of the website that were subsequently addressed. Users rated the website favourably on the dimensions of attractiveness, controllability, efficiency, intuitiveness and learnability, and gave it a total usability score of 80/100. Overall, this study demonstrates that OC survivors and caregivers are interested in using an online programme to improve QOL, and that providing tailored website content and features based on the person's role as survivor or caregiver is important in this population. © 2015 John Wiley & Sons Ltd.

    A user-centered design approach was used to refine the mHealth Pain Squad+ real-time pain self-management app for adolescents with cancer for its usability (defined as being easy to use, easy to understand, efficient to complete, and acceptable). Three iterative usability testing cycles involving adolescent observation and interview were used to achieve this objective. During each cycle, adolescents used the app while "thinking aloud" about issues encountered. Observed difficulties and errors were recorded and a semistructured interview about the experience was conducted. Using a qualitative conventional content analysis approach, themes related to app usability were identified. Participants required an average of 4.3 minutes to complete the pain assessment component of Pain Squad+. Overall, the app was acceptable. Problematic issues related to software malfunction, interface design flaws, and confusing text. Software revisions were made to address each issue. The multifaceted usability approach used provided insight into how a real-time app can be made acceptable to adolescents with cancer and succeeded in developing a Pain Squad+ app that is fit for future effectiveness testing.

    Many informed consent studies demonstrate that research subjects poorly retain and understand information in written consent documents. Previous research in multimedia consent is mixed in terms of success for improving participants' understanding, satisfaction, and retention. This failure may be due to a lack of a community-centered design approach to building the interventions. The goal of this study was to gather information from the community to determine the best way to undertake the consent process. Community perceptions regarding different computer-based consenting approaches were evaluated, and a computer-based consent was developed and tested. A second goal was to evaluate whether participants make truly informed decisions to participate in research. Simulations of an informed consent process were videotaped to document the process. Focus groups were conducted to determine community attitudes towards a computer-based informed consent process. Hybrid focus groups were conducted to determine the most acceptable hardware device. Usability testing was conducted on a computer-based consent prototype using a touch-screen kiosk. Based on feedback, a computer-based consent was developed. Representative study participants were able to easily complete the consent, and all were able to correctly answer the comprehension check questions. Community involvement in developing a computer-based consent proved valuable for a population-based genetic study. These findings may translate to other types of informed consents, including those for trials involving treatment of genetic disorders. A computer-based consent may serve to better communicate consistent, clear, accurate, and complete information regarding the risks and benefits of study participation. Additional analysis is necessary to measure the level of comprehension of the check-question answers by larger numbers of participants. The next step will involve contacting participants to measure whether understanding of

    The present study focused on the design, implementation, and evaluation of a personalized mobile patient guide system that utilizes smart phones, indoor navigation technology and a hospital information system (HIS) to address the difficulties that outpatients face in finding hospital facilities, recognizing their daily treatment schedule, and accessing personalized medical and administrative information. The present study was conducted in a fully digitized tertiary university hospital in South Korea. We developed a real-time location-based outpatient guide system that consists of Bluetooth access points (APs) for indoor navigation, an Android-based guide application, a guide server, and interfaces with the HIS. A total of 33 subjects and 43 outpatients participated in the usability test (UT) and the satisfaction survey, respectively. We confirmed that the indoor navigation feature can be applied to outpatient departments with precision using a position error test. The participants in the UT completed each scenario with an average success rate of 67.4%. According to the results, we addressed the problems and made improvements to the user interface by providing users with context-based guidance information. The satisfaction rating of the system was high, with an average score of 4.0 out of 5.0, showing its utility as a patient-centered hospital service. The innovative mobile patient guide system for outpatients is feasible and can be successfully implemented to provide personalized information with high satisfaction. Additionally, the issues identified and lessons learned from our experiences regarding task scheduling, indoor navigation, and usability should be considered when developing the system.

Facebook is widely used by Australian mothers and provides the opportunity to target social networks in order to maintain and increase physical activity.This mixed method study aimed to pilot and assess the usability of the Mums Step It Up Facebook app, a new team-based physical activity intervention for mothers with young children. A purposive sample of five "Captain" women with young children, were recruited through personal contacts. These women used the app to recruit 3-7 Facebook friends (with children under 5 to join their respective teams (total n = 25. The app encourages women to take 10,000 steps a day measured by a pedometer. Women used the app for 28 days to log steps, interact with team mates and monitor progress. Physical activity was assessed at two time points (baseline and final week using the Active Australia Survey. Usability testing with the five "Captain" women took place over two one hour face-to-face sessions. A questionnaire seeking feedback on the app was completed at time point two.Participants' total physical activity increased by an average of 177 minutes per week (p = 0.01. The complexity of the team forming process and issues using the Facebook environment, where a variety of devices and software platforms are used, was highlighted.A team-based Facebook app shows considerable promise for the recruitment and retention of participants to a social network-based physical activity intervention. A randomised controlled trial to further evaluate the effectiveness of the intervention is warranted.

    Usability testing can be used to evaluate human-computer interaction (HCI) and communication in shared decision making (SDM) for patient-provider behavioral change and behavioral contracting. Traditional evaluations of usability using scripted or mock patient scenarios with think-aloud protocol analysis provide a way to identify HCI issues. In this paper we describe the application of these methods in the evaluation of the Avoiding Diabetes Thru Action Plan Targeting (ADAPT) tool, and test the usability of the tool to support the ADAPT framework for integrated care counseling of pre-diabetes. The think-aloud protocol analysis typically does not provide an assessment of how patient-provider interactions are effected in "live" clinical workflow or whether a tool is successful. Therefore, "Near-live" clinical simulations involving applied simulation methods were used to compliment the think-aloud results. This complementary usability technique was used to test the end-user HCI and tool performance by more closely mimicking the clinical workflow and capturing interaction sequences along with assessing the functionality of computer module prototypes on clinician workflow. We expected this method to further complement and provide different usability findings as compared to think-aloud analysis. Together, this mixed method evaluation provided comprehensive and realistic feedback for iterative refinement of the ADAPT system prior to implementation. The study employed two phases of testing of a new interactive ADAPT tool that embedded an evidence-based shared goal setting component into primary care workflow for dealing with pre-diabetes counseling within a commercial physician office electronic health record (EHR). Phase I applied usability testing that involved "think-aloud" protocol analysis of eight primary care providers interacting with several scripted clinical scenarios. Phase II used "near-live" clinical simulations of five providers interacting with standardized

    Full Text Available In dem Beitrag werden Untersuchungsergebnisse vorgestellt, die sich mit dem Einsatz von Lehramts-Praktikanten aus Deutschland an der Universität Mugla Sıtkı Koçman im Rahmen der Deutschlehrerausbildung befassen. Mit der Arbeit soll nachgewiesen werden, dass sich die Motivation der türkischen Studierenden zum Deutschlernen durch die direkte Begegnung mit deutschen Lehramts-Praktikanten positiv beeinflusst werden kann. In diesem Zusammenhang wurde der Beitrag deutscher Lehramts-Praktikanten auf die Motivation der türkischen DaF-Studierenden ausgehend von den Studentenmeinungen untersucht. Generell fällt es türkischen Studierenden schwer, sich in der Fremdsprache zu äußern, zu sprechen oder zu schreiben, sobald man über Standardsituationen des Alltagskommunikation hinausgeht. Ein Grund dafür ist das Fehlen von Sprachkompetenz, aber auch von Erfahrungen bei konkreten Sprechanlässen und Sprechsituationen. Der Einsatz von Lehramts-Praktikanten, die im Rahmen des Erasmus-Programs im universitären Unterricht assistieren, soll diesem Mangel entgegen wirken. Die Studierenden sollen dabei unterstüzt werden, sich in der Fremdsprache zu äußern. Mit vorliegender Untersuchung wird der Frage nachgegangen, ob der Einsatz von Lehramts-Praktikanten aus Deutschland im universitären DaF-Unterricht in der Türkei das Interesse zum Deutschlernen fördert. Um den Beitrag deutscher Lehramts-Praktikanten im Rahmen des Erasmus-Programms im universitären Unterricht auf die Motivation türkischer Lehramtskandidaten zu ermitteln, wurde am Ende des Praktikums eine schriftliche Befragung durchgeführt. Die Form der Befragung war halbstrukturiert. Die Daten wurden mit einer qualitativen Methode ausgewertet.

Vor allem Kinder aus bildungsfernen Milieus und mit Migrationshintergrund sind hiervon betroffen (vgl. Becker/Lauterbach 2004; Diefenbach 2007; Rabe-Kleberg 2010. An dieser Einsicht knüpft das Forschungs- und Interventionsprojekt KidSmart – Medienkompetent zum Schulübergang an. Medienpädagogische Arbeit steht hier im Kontext der Vorbereitung auf den Schulübergang. Durch kreative Medienarbeit soll ein Gegengewicht zur eher passiven Mediennutzung geschaffen werden. Ziel ist es Bildungsunterschiede von Kindern bereits vor Schulbeginn auszugleichen.Already before starting school educational disadvantages in the part of reading and media socialization can be identified within Germany. Generally affected are children of less educated families and children with migration background (Becker/Lauterbach 2004; Diefenbach 2007; Rabe-Kleberg 2010. Therefore, an exceptional intervention and research project KidSmart – media competence by entering school was initiated in the area of early childhood education. Within this project media-pedagogical work is corresponding with preparation of entering school. The intention is to create a counterbalance to passive media use by creative media work. The scope of the project is to fight against early educational disadvantages.

    2013-01-01

    The objective of this paper is to explore human factors approaches to understanding the use of health information technology (HIT) by extending usability engineering approaches to include analysis of the impact of clinical context through use of clinical simulations. Methods discussed are considered on a continuum from traditional laboratory-based usability testing to clinical simulations. Clinical simulations can be conducted in a simulation laboratory and they can also be conducted in real-world settings. The clinical simulation approach attempts to bring the dimension of clinical context into stronger focus. This involves testing of systems with representative users doing representative tasks, in representative settings/environments. Application of methods where realistic clinical scenarios are used to drive the study of users interacting with systems under realistic conditions and settings can lead to identification of problems and issues with systems that may not be detected using traditional usability engineering methods. In conducting such studies, careful consideration is needed in creating ecologically valid test scenarios. The evidence obtained from such evaluation can be used to improve both the usability and safety of HIT. In addition, recent work has shown that clinical simulations, in particular those conducted in-situ, can lead to considerable benefits when compared to the costs of running such studies. In order to bring context of use into the testing of HIT, clinical simulation, involving observing representative users carrying out tasks in representative settings, holds considerable promise.

    The use of mobile devices and healthcare applications is increasing exponentially worldwide. This has lead to the need for the healthcare industry to develop a better understanding of the impact of the usability of mobile software and hardware upon consumer and health professional adoption and use of these technologies. There are many methodological approaches that can be employed in conducting usability evaluation of mobile technologies. More obtrusive approaches to collecting study data may lead to changes in study participant behaviour, leading to study results that are less consistent with how the technologies will be used in the real-world. Alternatively, less obstrusive methods used in evaluating the usability of mobile software and hardware in-situ and laboratory settings can lead to less detailed information being collected about how an individual interacts with both the software and hardware. In this paper we review and discuss several innovative mobile usability evaluation methods on a contiuum from least to most obtrusive and their effects on the quality of the usability data collected. The strengths and limitations of methods are also discussed.

A subgroup at particular risk is postmenopausal overweight women. The aim of this study was to assess the feasibility and effect of a 12-week ZumBeat dance intervention on cardiorespiratory fitness and psychosocial health. Postmenopausal women with a body mass index (BMI >30 kg/m2 or a waist circumference >94 cm who were not regularly physically active were asked to complete a 12-week ZumBeat dance intervention with instructed and home-based self-training sessions. Before and after the intervention, peak oxygen consumption (VO2peak was assessed on a treadmill; and body composition and several psychometric parameters (including quality of life, sports-related barriers and menopausal symptoms were investigated. Of 17 women (median age: 54 years; median BMI: 30 kg/m2 enrolled in the study, 14 completed the study. There was no apparent change in VO2peak after the 12-week intervention period (average change score: −0.5 mL/kg/min; 95% confidence interval: −1.0, 0.1; but, quality of life had increased, and sports-related barriers and menopausal symptoms had decreased. A 12-week ZumBeat dance intervention may not suffice to increase cardiorespiratory fitness in postmenopausal overweight women, but it increases women’s quality of life.

    The EvoBus company is very active in the field of public short-distance transport and corresponding transport systems. Its business purpose is to develop buses for fast, comfortable, environment-friendly and safe transport of passengers. With road transport being more than ever in the focus of public discussion (doubling of the number of vehicles world-wide by the year 2030), new solutions are called for. These should not only enhance the environmental compatibility of road transport, especially in inner-urban areas, but, moreover, safeguard mobility in view of the finiteness of fossil fuel resources. The author considers that the environmental issue is only to be solved in consecutive steps. After the diesel engine complying with the emission limits of the European emission abatement acts `Euro` 1, 2, and 3, and the gas engine, the future will lie in the fuel cell technology. (orig.) [Deutsch] Die EvoBus beschaeftigt sich sehr intensiv mit dem OePNV und OePNV-Systemen. In diesem Taetigkeitsfeld sehen wir es als unsere Aufgabe an, Omnibusse zu entwickeln, mit denen Personen schnell, komfortabel, umweltfreundlich und sicher transportiert werden koennen. Da der Strassenverkehr mehr denn je im Brennpunkt der oeffentlichen Verkehrsdiskussion steht (Verdoppelung der weltweiten Fahrzeugzahl bis zum Jahr 2030), brauchen wir neue Loesungen, die zum einen die Umweltvertraeglichkeit des Strassenverkehrs, insbesondere in den Innenstaedten, steigern, und zum anderen auch die Mobilitaet im Hinblick auf die endliche Verfuegbarkeit der fossilen Brennstoffe garantiert. Der Autor meint, dass die Loesung der Umweltproblematik nur in mehreren Schritten erfolgen kann, was bedeutet, dass ueber die Dieselmotoren mit Euro 1, 2 und 3 sowie dem Gasmotor die Zukunft in der Brennstoffzellen-Technologie zu suchen ist.

Doch in den Schulen findet forschendes Lernen noch wenig Beachtung. Dabei fördert die Methode wichtige Fähigkeiten der Schüler und bietet Chancen für eine zukunftsweisende Schulentwicklung. Die Jugendlichen erarbeiten in Forschungsprojekten eigenständig wissenschaftliche Fragestellungen, suchen Lösungswege, dokumentieren und präsentieren ihre Erkenntisse: Sie trainieren so wissenschaftliches Arbeiten, Eigenverantwortlichkeit, Teamfähigkeit und Zeitmanagement. Lehrer werden zu Lernbegleitern, Schulen öffnen sich für Kooperationen und entwickeln Alternativen zum 45-minütigen Unterrichtstakt. Die Fachbeiträge von Andreas Müller, Ilka Parchmann, Gerhard Roth u. a. untermauern die Praxisberichte aus lern- und entwicklungspsychologischer Sicht. Die Autoren sind sich einig: Wer bereits in der Schule forscht, ist in Studium und Beruf einen großen Schritt voraus....

    The contributions to the workshop ``Investigations on flooding in residual ponds from open-pit mining`` deal, inter alia, with the hydrochemical development of flushing waters, the stability of the water quality of residual lakes, especially under the impact of land contamination, the influence of brine receipts by flushed residual lakes, and with the microbiological ecology of residual lakes from mining. Furthermore, geophysical studies for demonstrating paths of flow and for calculating the depth and volume of residual lakes from open-pit mining are discussed. (MSK) [Deutsch] Die Beitraege zu dem Workshop `Untersuchungen zu Flutungen in Tagebaurestseen` befassen sich unter anderem mit der hydrochemischen Entwicklung von Flutungsgewaessern, mit der Qualitaetsstabilitaet von Restseewaessern - insbesonders bei Einwirkung von Altlasten - und mit den Einfluessen von Solezufluessen bei Restseeflutung sowie mit Untersuchungen zur mikrobiologischen Oekologie in Bergbaurestseen. Desweiteren werden geophysikalische Untersuchungen zum Nachweis von Fliesswegen und die Tiefen- und Volumenberechnung eines Tagebaurestlochsees erlaeutert. (MSK)

    The use of natural soils for low-cost removal of precipitated water and slightly polluted waste water has become an issue in legal procedures concerning water management. Although groundwater protection is given high priority, authorities do not have sufficient data on long-term effects and decomposition effects during passage to the soil. The Hydrology Department of Brandenburgische Technische Universitaet Cottbus, on behalf of the Thuringian Environmental Authority, investigated the state of the art of discharge of precipitated water into natural soils. The investigation is the first in a series of which the following effects are expected: Faster results by preliminary assessment of the applicability of the technique envisaged, use of this low-cost technology for waste water treatment in consideration of surface water protection. [German] Die Nutzung natuerlicher Boeden zur kostenguenstigen Beseitigung von Niederschlagswasser aber auch von schwachbelastetem Abwasser ist eine Variante der Abwasserbeseitigung, die zunehmend Antragsgegenstand in wasserrechtlichen Verfahren ist. Der Schutz des Grundwassers ist dabei in besonderem Masse zu beachten. Die Einschaetzung der Eignung dieser Variante ist Behoerden aufgrund unzureichender Aussagen zum Langzeitverhalten und zu Abbaueffekten waehrend der Bodenpassage derzeit nicht moeglich. Durch die THUeRINGER LANDESANSTALT FUeR UMWELT erhielt der Lehrstuhl Wassertechnik der Brandenburgischen Technischen Universitaet Cottbus den Auftrag, im Rahmen einer Literaturstudie, den gegenwaertigen Stand der schadlosen Versickerung von Niederschlagswasser in natuerlichen Boeden aufzuzeigen. Die Literaturrecherche bildet den ersten Schritt einer Untersuchungsreihe, von der folgende Wirkungen erwartet werden: Verfahrensbeschleunigung durch Bewertbarkeit der Eignung der Behandlungsvariante, Nutzung dieser kostenguenstigen Umwelttechnologie zur Behandlung von Abwasser unter Beachtung des Gewaesserschutzes.

    Full Text Available Das in den letzten Jahren spürbare Bestreben der litauischen Gesetzgeber, Untertitelung von Fernsehfilmen zwecks Fremdsprachenerwerb gesetzlich anzuordnen, löste eine Auseinandersetzung in der Öffentlichkeit aus, die sich in der Presse sowie im Internet widerspiegelt und als Anstoß zum vorliegenden Beitrag dient. Diese Arbeit stellt den Versuch dar, die Möglichkeiten und Grenzen der Untertitelung als eines Mittels zum Fremdsprachenerwerb zu untersuchen. Auf Grund der fehlenden wissenschaftlichen Forschungen in diesem Bereich sollen dabei empirische Betrachtungen und die vergleichende Textanalyse von Original und Übersetzung als Hilfe dienen. Auch wenn die Relevanz der Untertitelung für den Fremdsprachenerwerb nicht bestreitbar ist, ist sie aber zugleich nicht zu überschätzen: Durch die lediglich für diese Form der audiovisuellen Übersetzung charakteristischen Merkmale (kurze Einblendezeit, kondensierte Sprache und begrenzte Übertragungsmöglichkeiten von Realia-Begriffen, Phraseologismen, Intertextualismen, dem Wortspiel etc. bleiben dem Zuschauer oft sprachliche Stilmittel vorenthalten und der in allen Übersetzungsbereichen vorkommende unausweichliche Sinn- und Wirkungsverlust des Originals wird erheblich verstärkt. Anbetracht der erwähnten Aspekte und der häufigen fehlerhaften Übersetzungen sollen Untertitel nur als Hilfsmittel beim Fremdsprachenerwerb angewendet werden, wobei herkömmliche Lehr- und Lernstrategien von Fremdsprachen in den Vordergrund treten müssen.

    Medication history errors are common at admission, but can be mitigated through the implementation of medication reconciliation (MR). We designed multi-media software to assist clinicians with collection of an admission history. This manuscript describes a naturalistic usability study conducted on the hospital wards. Our goals were to 1) estimate the impact of our workflow upon departmental productivity and 2) determine the ability of our software to detect discrepancies. We furnished clinical pharmacists with our application on a tablet PC and asked them to collect a bedside history. We used 1) time-motion analysis to estimate cycle-time and 2) chart reviews to estimate error detection rates. Our intervention detected an average of 7.7 discrepancies per admission (11.7 per pharmacy-shift). A panel rated 67% of these discrepancies as 'high' or 'very high' risk. The cycle-time per admission was slightly longer than usual care processes (20.5 min vs. 17.9 min), but included a bedside interview. In general, pharmacists agreed that the technology improved the completeness and accuracy of a medication history. However, workflow leveling strategies are important to implementing a durable process. In conclusion, a pharmacist-mediated, patient-centered technology holds promise for improving the quality of MR and overall clinical performance.

    Rund drei Viertel der anthropogen bedingten CO2-Emissionen werden weltweit in Ballungsräumen verursacht, wovon ein guter Teil auf die kaum abschätzbare Zahl täglicher Personen- und Güterverkehre mit Nahdistanzen zurückzuführen ist. Der Verkehrssektor in Deutschland ist für ein Viertel des Endenergieverbrauchs verantwortlich und trägt mit einem knappen Fünftel der Emissionen in nicht unerheblichem Umfang zum Ausstoß von Treibhausgasen bei. Der Straßenverkehr macht innerhalb des Gesamtverkehrs mehr als zwei Drittel der Emissionen aus, europaweit sind es 80 Prozent. Hier wird langfristig sogar mit einer Verdopplung des Energieverbrauchs im Straßensektor gerechnet.

  8. Melker Meilensteine auf dem Weg in ein naturwissenschaftliches Zeitalter - Glanzlichter der Ausstellung zum Internationalen Astronomiejahr 2009 in der Melker Stiftsbibliothek.

    Science.gov (United States)

    Beck, Paul G.; Zotti, Georg

    2009-06-01

    Das Mittelalter wird weithin als die dunkle Epoche in der Geschichte der Europäischen Wissenschaften betrachtet, und insbesondere das Leben in den Klöstern galt lange Zeit als frei von jeglichem Interesse für Naturwissenschaften abseits der Medizin. Im Mittelalter galt die Astronomie bloß als Mittel zum Zweck, um religiöse und zivile Kalender erstellen zu können. Durch den Bestand der Handschriftenkammer der Melker Stiftsbibliothek eröffnet sich uns eine neue Sichtweise auf das gegen Ende des Mittelalters wachsende Interesse an den Naturwissenschaften. Dies wurde durch die starke Aufwertung der Klosterbibliothek im Rahmen der 'Melker Reform' im 15. Jahrhundert noch weiter verstärkt. Diese Epoche fällt mit der Frühphase der Universität Wien und der 'ersten Wiener Schule der Astronomie' zusammen. Dieser Artikel beleuchtet ausgewählte astronomischen Werke in der Melker Stiftsbibliothek zwischen dem frühen 9 und dem 18. Jahrhundert. Einen Schwerpunkt stellt das Wirken der Wiener Schule der Astronomie dar, wobei wir u.a. die Melker Abschrift von Peuerbachs Gutachten über den Kometen von 1456 sowie die im Stift Melk durchgeführte Beobachtung der Mondfinsternis von 1457 durch Regiomontanus und Peuerbach beleuchten. Dieser Beitrag ist der einführende Übersichtsartikel zum Ausstellungsprojekt in der Melker Stiftsbibliothek im Rahmen des Internationalen Jahres der Astronomie 2009. The medieval period is commonly seen as a dark epoch for science in Europe. Especially monasteries were seen as institutions without interest in natural sciences except for medicine. Astronomy was allegedly only a tool to construct religious and civil calendars. The inventory of the medieval manuscript collection of the library of the Abbey of Melk allows a new view on the growing interest in the exact sciences towards the end of the medieval ages. This interest was intensified through the increased importance of the monastery library due to the monastery reform concept, created in

Monitoring of prostate-specific antigen (PSA) values is the current standard of care in the follow-up. Imaging is recommended only for symptomatic patients and/or for further therapeutic options. For detection of local recurrence magnetic resonance imaging (MRI) of the prostate is acknowledged as the method of choice. Good results for primary diagnosis were found especially in combination with functional techniques, whereas in recurrent prostate cancer only few studies with heterogeneous study design are available for prostate MRI. Furthermore, changes in different MRI modalities due to radiation therapy have been insufficiently investigated to date. As the initial results were promising prostate MRI and available therapeutic options for detection of local recurrence should be considered in patients with increased PSA. (orig.) [German] Fuer Patienten mit Prostatakarzinom stellt die Radiatio eine potenziell kurative lokale Therapieoption dar. Im Rahmen der Nachsorge nach lokal kurativ intendierter Therapie wird aktuell der Verlauf des PSA-Werts (PSA prostataspezifisches Antigen) kontrolliert, der Einsatz bildgebender Verfahren wird lediglich bei symptomatischen Patienten und/oder zur Planung einer Salvagetherapie empfohlen. Die MRT der Prostata stellt derzeit die Methode der Wahl zur lokalen Rezidivdiagnostik dar. Insbesondere in Verbindung mit funktionellen Untersuchungstechniken zeigen Studien gute Ergebnisse in der Primaerdiagnostik. Zum Einsatz der MRT der Prostata in der Rezidivsituation wurden bisher nur wenige Studien mit heterogenem Studiendesign publiziert. Auch die in der MRT nach Bestrahlung sichtbaren Veraenderungen in den unterschiedlichen Modalitaeten sind noch wenig evaluiert. Da die ersten Studienergebnisse auch bei Patienten nach Radiatio viel versprechend sind, sollte bei unklarem PSA-Anstieg und vorhandener Therapieoption eine MRT der Prostata zur

    Classical destructive test methods are fixed part of industrial sectors for decades such as aerospace, automotive, railway and power plants. A high degree of standardization of procedures, and training in form of an ISO standard are present, but not in non-destructive testing of civil engineering (ZfPBau). Except for the rebound hammer NDT methods in civil engineering are not standardized. Also of personnel qualifications can be found in regulations very few requirements, although it is obvious that this is an indispensable prerequisite for the proper application of the procedures and reliable inspection results. In this contribution experiences with a presented training concept in which the construction inspector will trained to DIN 1076 in a two-day course. Here are the necessary conditions worked out, such as the creation of suitable test bodies or the definition of necessary course content for establishing training courses. [German] Klassische zerstoerungsfreie Pruefverfahren sind seit Jahrzehnten fester Bestandteil industrieller Bereiche wie Luftfahrt, Automotive, Eisenbahn und Kraftwerke. Ein hoher Normungsgrad der Verfahren und Ausbildungsstandards in Form einer ISO-Norm liegen vor. Bei der zerstoerungsfreien Pruefung im Bauwesen (ZfPBau) ist das anders. Bis auf den Rueckprallhammer sind ZfPBau-Verfahren nicht genormt. Auch zur Personalqualifikation finden sich in Regelwerken nur sehr wenige Anforderungen, obwohl es offensichtlich ist, dass dies eine unverzichtbare Voraussetzung fuer die richtige Anwendung der Verfahren und zuverlaessige Pruefaussagen ist. In diesem Beitrag werden Erfahrungen mit einem Ausbildungskonzept vorgestellt, bei dem Bauwerkspruefer nach DIN 1076 in einem zweitaegigen Lehrgang ausgebildet werden. Dabei werden die notwendigen Voraussetzungen heraus gearbeitet, wie z.B. die Erstellung von geeigneten Testkoerpern oder die Festlegung notwendiger Kursinhalte, die zum Etablieren von Ausbildungskursen erforderlich sind.

    Full Text Available Das Forum Kommunikationskultur der Gesellschaft für Medienpädagogik und Kommunikationskultur (GMK steht im Jahr 2017 unter dem Anspruch, sich mit Fragen der Qualitätsentwicklung medienpädagogischen Handelns in Wissenschaft und Praxis auseinanderzusetzen. Dabei soll besonderes Augenmerk auf Fragen der Professionalisierung und der Entwicklung von Standards gelegt werden. Zu diesen Fragen stellen wir im Folgenden ausgewählte Thesen mit ergänzenden und erweiternden Erläuterungen im Sinne eines programmatischen Textes zur Diskussion. Die mit diesem Papier anzustossende Diskussion soll zunächst einer konstruktiv-weiterführenden internen Klärung wichtiger Fragen medienpädagogischer Praxis und Forschung dienen und dabei auch anzeigen, welche Positionen in der Community konsensfähig sind und welche möglicherweise strittig erscheinen. Zugleich sollen die Thesen und die Diskussion zu einer Positionsbestimmung der GMK bezüglich praktischer und wissenschaftlicher medienpädagogischer Arbeit nach aussen beitragen. Mit der Diskussion ist das Ziel verbunden, künftige Bedarfe für Handlungs- und Forschungsfelder der Medienpädagogik – jedoch ohne Anspruch auf Vollständigkeit – zu identifizieren. Um der Prägnanz und Kürze willen, wird der zu jeder These gehörende Hintergrund nur knapp angedeutet, ohne die damit verbundenen (teils sehr umfassenden Diskurse im Detail nachzuzeichnen. Angegebene Literaturbezüge sollen jeweils beispielhaft auf differenzierende und tiefergehende Ausführungen verweisen. Die Thesenfolge beginnt mit Überlegungen zum technikinduzierten gesellschaftlichen Wandel („Digitalisierung“ und seiner Bedeutung für die Medienbildung. Dies vorausschickend, gehen wir auf Fragen der Qualifizierung und Professionalisierung für praktisches Handeln sowie auf die Rolle der Medienpädagogik als Wissenschaft und schliessend auf den Stellenwert von Standards zur Orientierung und Reflexion ein.

    inclination angle profile of the Grossglockner mountain is followed on the test stand with a speed of 55 km/h without overheating of the cooling system. After optimization of the cooler design and positioning, the new vehicle was able to meet the specifications while the first of the two vehicles only achieved 35 km/h without overheating of the cooling system. Finally, a theoretical investigation identified the measures that should be taken to achieve sufficient cooling in countries with hot climates, e.g. the USA. It was found that it would be sufficient to raise the coolant temperature from 90 C to about 110 C to ensure good performance in these climate zones. (orig.) [German] Ziel der vorliegenden Arbeit ist die thermodynamische Analyse und Optimierung eines Brennstoffzellensystems zum Antrieb von Kraftfahrzeugen. Der Fokus ist im Wesentlichen auf die Kuehlung des Brennstoffzellenstapelmoduls gelegt, wobei aufgrund der Vielzahl an Schnittstellen zwischen der Kuehlung und den anderen Teilsystemen (Wasserstoff- und Luftversorgung) auch eine ganzheitlichere Betrachtung erforderlich ist. Ausgangspunkt der Untersuchungen ist ein bestehendes Brennstoffzellenfahrzeug, anhand dessen in einem ersten Schritt experimentelle Untersuchungen auf Systempruefstaenden und im Klimawindkanal durchgefuehrt werden. Die gewonnenen Messdaten dienen zum einen der Darstellung des Ist-Zustands und zur Ermittlung des Grenzbereichs der Waermeabfuhr an die Umgebung ueber das Brennstoffzellen-Kuehlsystem. Zum anderen werden sie zur Validierung eines dynamischen Kuehlsystemsimulationsmodells herangezogen. Mittels dieses Simulationsmodells werden anschliessend im Rahmen von Sensitivitaetsanalysen die wesentlichen Einflussfaktoren zur Steigerung der Waermeabfuhr an die Umgebung ermittelt. Die daraufhin durchgefuehrten Optimierungen betreffen die Verschaltung der Systemkomponenten sowie deren Auslegung und Platzierung im Fahrzeugvorderwagen. Auf Basis dieser und weiterer Erkenntnisse wird ein weiteres

    While the first part of the symposium was dedicated to half-timbered buildings in the traditional style of Lausitz, Bohemia and Silesia, the second part discussed passive buildings. [German] Das Umgebindehaus ist ein weltweit einmaliger Haustyp und zum anderen ist es ein traditionelles Haus unserer Region der Oberlausitz und angrenzender Teile von Boehmen und Schlesien. Das Symposium behandelt das Umgebindehaus in Vergangenheit und Gegenwart und will Motivation und Ansaetze geben, dieses wunderschoene Baukulturgut zu erhalten und unter modernen Wohn-, Arbeits- und Lebensbedingungen zu nutzen. Der zweite Teil der Tagung ist nicht minder wichtig. Beim Passivhaus geht es im wesentlichen darum, Heizwaermeverluste im Winter so klein zu halten, dass sie von den Gewinnen (Sonnenenergie, inneres Waermeaufkommen u.a.) gedeckt werden koennen. Damit wird der Waermeschutz des Gebaeudes vielleicht bis an die Grenzen getrieben und es entstehen neue Anforderungen an das Energiemanagement und die Qualitaet der technischen Gebaeudeausruestung.

We empirically investigate how decision makers behave when making these decisions, As a baseline we compare this intuitive decision making with the optimal decision making described by Markowitz' portfolio theory. Our results show that intuitive behavior is quite different from optimal behavior. Especially, subjects did not hold the optimal risky portfolio and they trade much more than predicted by portfol...

  19. Zum Bildungspotenzial biblischer Texte

    Directory of Open Access Journals (Sweden)

    Theis, Joachim

    2017-11-01

    Full Text Available Biblical education as a holistic process goes far beyond biblical learning. It must be understood as a lifelong process, in which both biblical texts and their understanders operate appropriating their counterpart in a dialogical way. – Neither does the recipient’s horizon of understanding appear as an empty room, which had to be filled with the text only, nor is the latter a dead material one could only examine cognitively. The recipient discovers the meaning of the biblical text recomposing it by existential appropriation. So the text is brought to live in each individual reality. Both scientific insights and subjective structures as well as the understanders’ community must be included to avoid potential one-sidednesses. Unfortunately, a special negative association obscures the approach of the bible very often: Still biblical work as part of religious education appears in a cognitively oriented habit, which is neither regarding the vitality and sovereignty of the biblical texts nor the students’ desire for meaning. Moreover, the bible is getting misused for teaching moral terms or pontifications. Such downfalls can be disrupted by biblical didactics which are empowerment didactics. Regarding the sovereignty of biblical texts, these didactics assist the understander with his/her individuation by opening the texts with focus on the understander’s otherness. Thus each the text and the recipient become subjects in a dialogue. The approach of the Biblical-Enabling-Didactics leads the Bible to become always new a book of life. Understanding them from within their hermeneutics, empowerment didactics could be raised to the principle of biblical didactics in general and grow into an essential element of holistic education.

    The Standard for ``means for the subsequent sealing of joints of gaspipes laid in the ground`` (DIN 30658) required a supplement, after various processes were developed, not only for sealing the leaking sleeve joints, but for cladding long sections of pipe with foil or woven hoses. The functional tests on sealed sleeve joints taken over largely unchanged were supplemented by specific tests of the cladding, which concern the opening of existing house connection and the production of new ones, the bridging of corrosion damage and unused tee-offs, and for woven hoses the behaviour during pipe fractures with the raising of the maximum permitted working pressure from 1 bar in DIN 30658 to 4 bar. There is a report on the results of a research project financed by DVGW for working out test proceedures and requirements. (orig.) [Deutsch] Die Norm ueber ``Mittel zum nachtraeglichen Abdichten von Verbindungen erdverlegter Gasleitungen`` (DIN 30658) bedurfte einer Ergaenzung, nachdem verschiedene Verfahren entwickelt wurden, nicht nur gezielt die undichten Muffenverbindungen abzudichten, sondern laengere Leitungsabschnitte mit Folien- oder Gewebeschlaeuchen auszukleiden. Die im wesentlichen unveraendert uebernommenen Funktionspruefungen an abgedichteten Muffenverbindungen wurden durch spezifische Pruefungen der Auskleidung ergaenzt, die das Oeffnen bestehender und die Erstellung neuer Hausanschluesse, die Ueberbrueckung von Korrosionsschaeden und stillgelegten Abgaengen sowie bei Gewebeschlaeuchen das Verhalten bei Rohrbruechen bei Anhebung des max. zulaessigen Betriebsdruckes von 1 bar in DIN 30658 auf 4 bar betreffen.

    The work reported was to investigate the changes caused at the crack tip of a specimen with incipient crack and to assess their effects with regard to component fracture. The steels selected for testing are the pressure vessel steels 10MnMoNi5-5 and 17MoV8-4, and the experiments were made with CT-25 specimens. The conclusion drawn from the results obtained is that the WPS effect is due to a stronger energy dissipation in the prestressed area ahead of the crack tip, assisted by intrinsic stress-induced crack closing. (orig./CB) [Deutsch] Das Ziel dieser Arbeit ist es, die durch eine Vorbeanspruchung angerissener Proben hervorgerufenen Veraenderungen an der Rissspitze und ihre Auswirkungen auf das Bruchverhalten zu untersuchen.

Die Autoren kommen zum Schluss, dass der WPS-Effekt mit einer staerkeren Energiedissipation in der vorgeschaedigten Prozesszone vor der Rissspitze, unterstuetzt durch eigenspannungsbedingtes Rissschliessen, erklaert werden kann.

    Strains of bacteria were investigated with a view to their applicability and efficiency in enhanced recovery of petroleum. The mechanisms of enhanced recovery with bacteria were to be clarified as well. The experiments were carried out as static autoclave experiments without bedrock and as dynamic flooding experiments in a model pore space (Bentheim sandstone and carbonate rock) under the conditions of North German petroleum deposits. The static experiments carried out preliminary to the more time-consuming dynamic flooding experiments were to help with an optimized design of the injection experiments. (orig.) [Deutsch] Die vorliegende Arbeit hat zum Ziel, entoelungswirksame Bakterienstaemme zu untersuchen und hinsichtlich der durch sie bewirkten Erhoehung des Entoelungsgrades zu bewerten. Gleichzeitig sollen die Mechanismen aufgeklaert werden, die der Entoelungsverbesserung durch Einsatz von Bakterien zugrunde liegen. Die Experimente wurden als statische Autoklavenversuche ohne Lagerstaettengestein sowie als dynamische Flutversuche im Modellporenraum (Bentheimer Sandstein und karbonatisches Gesteinsmaterial) unter Bedingungen norddeutscher Lagerstaetten durchgefuehrt. Die statischen Versuche, die als Auswahltests den aufwendigeren dynamischen Flutversuchen vorgeschaltet waren, sollten dazu beitragen, die Flutversuche gezielt konzipieren zu koennen. (orig./EF)

How do these results relate to the extracurricular realities of learners and the seemingly opposing natural artificiality of language teaching? What are the implications of this when dealing with languages in the foreign language classroom and CLIL?

Conclusion: The infrastructural prerequisites of the present curricular concepts and the degree of implementation of the Q13 according to the requirements of the new ÄApprO diverge significantly among the various medical faculties. The efforts made to produce a qualitatively high standard of teaching with regard to the multifaceted questions concerning the support for severely and terminally ill patients is as much reflected in the survey, as the special implications of an independent Chair for palliative medicine for the implementation of the requirements by law. The participation of various occupational groups in this survey as well as the broad spectrum of those involved highlights the interdisciplinary and multi-professional dimension of teaching in palliative care.

    Full Text Available Zum Sprachgebrauch Fr. R. Kreutzwalds anhand seiner Beiträge in der Wochenschrift „Das Inland“ Zusammenfassung Im vorliegenden Aufsatz wird der Sprachgebrauch Friedrich Reinhold Kreutzwalds anhand seiner Beiträge in der Wochenschrift „Das Inland“ betrachtet. Zuerst wird ein kurzer Überblick über Kreutzwald als Mitarbeiter des „Inlands“ gegeben, danach geht man auf die Behandlung seiner Sprache ein. Die Autoren und Herausgeber des deutschsprachigen „Inlands“ waren in der Regel Deutschbalten, deren Muttersprache Deutsch war. Mit Kreutzwald verhält es sich anders. Er war ein gebürtiger Este, der sich die deutsche Sprache angeeignet hatte. Seine Bildung von der Grundschule bis zum Abschluss der Universität hatte er in deutscher Sprache erhalten. Dieser Umstand gibt Anlass zur Frage, ob in Kreutzwalds deutscher Sprache Merkmale vorkommen, die seine estnische Herkunft verraten. Bei der Analyse des Sprachgebrauchs von Kreutzwald werden folgende Ebenen des Sprachsystems berücksichtigt: Lexik (Wortwahl, Grammatik (Morphologie und Syntax und Stilfiguren, vorwiegend Mittel der Bildlichkeit. Da die untersuchten Texte etwa 170 Jahre alt sind, ist es selbstverständlich, dass in ihnen Wörter und Wendungen vorkommen, die heute als veraltet oder altertümlich gelten. Neben dem veralteten Wortgut benutzt Kreutzwald recht viele Wörter und Wendungen, die der gehobenen Stilschicht angehören. Wörter aus den so genannten niederen Stilschichten kommen in Kreutzwalds Schriften bedeutend seltener vor. Wider Erwarten erscheint ausgesprochenes deutschbaltisches Wortgut in der Publizistik von Kreutzwald kaum. Hervorzuheben sind aber okkasionelle Bildungen von Kreutzwald. Da es nicht für jeden estnischen Begriff oder jedes estnische Wort eine adäquate deutsche Entsprechung gab, musste Kreutzwald selbst neue Wörter bilden. Im Bereich der Morphologie gibt es nicht viele Besonderheiten. Ein typisches Merkmal ist die Bevorzugung der Formen, die

    The paper reviews the available, fundamental measuring methods relying on {gamma}-spectroscopy for their possible application in whole-body and partial-body counters for detection of manifold incorporation of radionuclides. Particular emphasis is placed on the response functions of various detectors, the assembly, the differentiated radioactivity distribution in the body, the various components of background activity and the corresponding suppression mechanisms, and possible ways of using the energy dependence for optimised detection of specific {gamma} energies in a given body region. Criteria and relations as well as their advantages and drawbacks are discussed.

    Implementing security mechanisms such as access control for clinical use is a challenging research issue in BSN due to its required heterogeneous operating responses ranging from chronic diseases management to emergency care. To ensure the clinical uptake of the BSN technology, appropriately...... designed security mechanisms are essential. Several experimental sensor network platforms have emerged in recent years targeted for clinical use. However, few of them consider the importance of security issues such as privacy and access control, and how these can impact the usability of the platform, while...... others develop BSN security without considering how a prototype implementation would be received by clinicians in real-life situations. The purpose of this paper is to present our initial effort in building a flexible experimental platform for providing a basic infrastructure with symmetric AES...

    User testing, a method of assessing website usability, can be a cost-effective and easily administered process to collect information about a website's effectiveness. A user experience (UX) team at an academic health sciences library has employed user testing for over three years to help refine the library's home page. Test methodology used in-person testers using the "think aloud" method to complete tasks on the home page. Review of test results revealed problem areas of the design and redesign; further testing was effective in refining the page. User testing has proved to be a valuable method to engage users and provide feedback to continually improve the library's home page.

    Full Text Available Disease maps are important tools in the management of disease. By communicating risk, disease maps can help raise awareness of disease and encourage farmers and veterinarians to employ best practice to eliminate the spread of disease. However, despite the importance of disease maps in communicating risk and the existence of various online disease maps, there are few studies that explicitly examine their usability. Where disease maps are complicated to use, it seems that they are unlikely to be used effectively. The paper outlines an attempt to create an open access, online, searchable map of incidents of bovine tuberculosis in England and Wales, and analyzes its usability among veterinarians. The paper describes the process of creating the map before describing the results of a series of usability trials. Results show the map to score highly on different measures of usability. However, the trials also revealed a number of social and technical limitations and challenges facing the use of online disease maps, including reputational dangers, role confusion, data accuracy, and data representation. The paper considers the challenges facing disease maps and their potential role in designing new methodologies to evaluate the effectiveness of disease prevention initiatives.

  20. Naturalistic Decision Making in Power Grid Operations: Implications for Dispatcher Training and Usability Testing

    Energy Technology Data Exchange (ETDEWEB)

    Greitzer, Frank L.; Podmore, Robin

    2008-11-17

    The focus of the present study is on improved training approaches to accelerate learning and improved methods for analyzing effectiveness of tools within a high-fidelity power grid simulated environment. A theory-based model has been developed to document and understand the mental processes that an expert power system operator uses when making critical decisions. The theoretical foundation for the method is based on the concepts of situation awareness, the methods of cognitive task analysis, and the naturalistic decision making (NDM) approach of Recognition Primed Decision Making. The method has been systematically explored and refined as part of a capability demonstration of a high-fidelity real-time power system simulator under normal and emergency conditions. To examine NDM processes, we analyzed transcripts of operator-to-operator conversations during the simulated scenario to reveal and assess NDM-based performance criteria. The results of the analysis indicate that the proposed framework can be used constructively to map or assess the Situation Awareness Level of the operators at each point in the scenario. We can also identify the mental models and mental simulations that the operators employ at different points in the scenario. This report documents the method, describes elements of the model, and provides appendices that document the simulation scenario and the associated mental models used by operators in the scenario.

    Full Text Available Abstract - The use of mobile devices for delivering learning tools is an attractive concept. Termed mobile learning (m-learning, this new technology allows people to participate in learning activities without being tied to a fixed location and provides users with convenient and flexible access to learning resources anytime and anywhere. While many m-learning applications have been developed to date, most provide tools to help students’ with specific learning tasks rather than a general interface to online courses. Few sup-port online learning communities or allow users to download multimedia learning content. These features would engage mobile users and enable them to interact with one another, thus allowing them to participate in group learning activities despite their changing location. In this article, we describe an m-learning system which we have developed which aims to incorporate these facilities. This system provides access to multimedia learning resources and supports mobile users in an interactive synchronous learning environment with their desktop peers. Details of the evaluation techniques which we utilised to appraise the system are provided and the results are presented. Feedback suggests that the features offered by our system are beneficial for collaborative m-learning.

  2. Protocol for Usability Testing and Validation of the ISO Draft International Standard 19223 for Lung Ventilators

    Science.gov (United States)

    2017-01-01

    Background Clinicians, such as respiratory therapists and physicians, are often required to set up pieces of medical equipment that use inconsistent terminology. Current lung ventilator terminology that is used by different manufacturers contributes to the risk of usage errors, and in turn the risk of ventilator-associated lung injuries and other conditions. Human factors and communication issues are often associated with ventilator-related sentinel events, and inconsistent ventilator terminology compounds these issues. This paper describes our proposed protocol, which will be implemented at the University of Waterloo, Canada when this project is externally funded. Objective We propose to determine whether a standardized vocabulary improves the ease of use, safety, and utility as it relates to the usability of medical devices, compared to legacy medical devices from multiple manufacturers, which use different terms. Methods We hypothesize that usage errors by clinicians will be lower when standardization is consistently applied by all manufacturers. The proposed study will experimentally examine the impact of standardized nomenclature on performance declines in the use of an unfamiliar ventilator product in clinically relevant scenarios. Participants will be respiratory therapy practitioners and trainees, and we propose studying approximately 60 participants. Results The work reported here is in the proposal phase. Once the protocol is implemented, we will report the results in a follow-up paper. Conclusions The proposed study will help us better understand the effects of standardization on medical device usability. The study will also help identify any terms in the International Organization for Standardization (ISO) Draft International Standard (DIS) 19223 that may be associated with recurrent errors. Amendments to the standard will be proposed if recurrent errors are identified. This report contributes a protocol that can be used to assess the effect of standardization in any given domain that involves equipment, multiple manufacturers, inconsistent vocabulary, symbology, audio tones, or patterns in interface navigation. Second, the protocol can be used to experimentally evaluate the ISO DIS 19223 for its effectiveness, as researchers around the world may wish to conduct such tests and compare results. PMID:28887292

    Safety planning is a brief intervention that has become an accepted practice in many clinical settings to help prevent suicide. Even though it is quick compared to other approaches, it frequently requires 20 min or more to complete, which can impede adoption. A self-administered, Web-based safety planning application could potentially reduce clinician time, help promote standardization and quality, and provide enhanced ability to share the created plan. The aim of this study was to design, build, and test the usability of a Web-based, self-administered safety planning application. We employed a user-centered software design strategy led by a multidisciplinary team. The application was tested for usability with a target sample of suicidal patients. Detailed observations, structured usability ratings, and Think Aloud procedures were used. Suicidal ideation intensity and perceived ability to cope were assessed pre-post engagement with the Web application. A total of 30 participants were enrolled. Usability ratings were generally strong, and all patients successfully built a safety plan. However, the completeness of the safety plan varied. The mean number of steps completed was 5.5 (SD 0.9) out of 6, with 90% (27/30) of participants completing at least 5 steps and 67% (20/30) completing all 6 steps. Some safety planning steps were viewed as inapplicable to some individuals. Some confusion in instructions led to modifications to improve understandability of each step. Ratings of suicide intensity after completion of the application were significantly lower than preratings, pre: mean 5.11 (SD 2.9) versus post: mean 4.46 (SD 3.0), t 27 =2.49, P=.02. Ratings of ability to cope with suicidal thoughts after completion of the application were higher than preratings, with the difference approaching statistical significance, pre: mean 5.93 (SD 2.9), post: mean 6.64 (SD 2.4), t 27 =-2.03, P=.05. We have taken the first step toward identifying the components needed to maximize usability of a self-administered, Web-based safety planning application. Results support initial consideration of the application as an adjunct to clinical contact. This allows for the clinician or other personnel to provide clarification, when needed, to help the patient build the plan, and to help review and revise the draft. ©Edwin D Boudreaux, Gregory K Brown, Barbara Stanley, Rajani S Sadasivam, Carlos A Camargo Jr, Ivan W Miller.

    Full Text Available A major learning difficulty of Japanese foreign language (JFL learners is the complex composition of two syllabaries, hiragana and katakana, and kanji characters adopted from logographic Chinese ones. As the number of Japanese language learners increases, computer-assisted Japanese language education gradually gains more attention. This study aimed to adopt a Japanese word segmentation system to help JFL learners overcome literacy problems. This study adopted MeCab, a Japanese morphological analyzer and part-of-speech (POS tagger, to segment Japanese texts into separate morphemes by adding spaces and to attach POS tags to each morpheme for beginners. The participants were asked to participate in three experimental activities involvingwatching two Japanese videos with general or segmented Japanese captions and complete the Nielsen’s Attributes of Usability (NAU survey and the After Scenario Questionnaire (ASQ to evaluate the usability of the learning activities. The results of the system evaluation showed that the videos with the segmented captions could increase the participants’ learning motivation and willingness to adopt the word segmentation system to learn Japanese.

    ImPRO is a computer based procedure in both flowchart and success logic tree. It is evaluated on the basis of computer based procedure guidelines. It satisfies most requirements such as presentations and functionalities. Besides, SGTR has been performed with ImPRO to evaluate reading comprehension and situation awareness. ImPRO is a software engine which can interpret procedure script language, so that ImPRO is reliable by nature and verified with formal method. One bug, however, had hidden one year after release, but it was fixed. Finally backup paper procedures can be prepared on the same format as VDU in case of ImPRO failure. (authors)

    Computer screen videos (CSVs) and users' facial expressions videos (FEVs) are recommended to evaluate systems performance. However, software combining both methods is often non-accessible in clinical research fields. The Observer-XT software is commonly used for clinical research to assess human behaviours. Thus, this study reports on the combination of CSVs and FEVs, to evaluate a graphical user interface (GUI). Eight physiotherapists entered clinical information in the GUI while CSVs and FEVs were collected. The frequency and duration of a list of behaviours found in FEVs were analysed using the Observer-XT-10.5. Simultaneously, the frequency and duration of usability problems of CSVs were manually registered. CSVs and FEVs timelines were also matched to verify combinations. The analysis of FEVs revealed that the category most frequently observed in users behaviour was the eye contact with the screen (ECS, 32±9) whilst verbal communication achieved the highest duration (14.8±6.9min). Regarding the CSVs, 64 problems, related with the interface (73%) and the user (27%), were found. In total, 135 usability problems were identified by combining both methods. The majority were reported through verbal communication (45.8%) and ECS (40.8%). "False alarms" and "misses" did not cause quantifiable reactions and the facial expressions problems were mainly related with the lack of familiarity (55.4%) felt by users when interacting with the interface. These findings encourage the use of Observer-XT-10.5 to conduct small usability sessions, as it identifies emergent groups of problems by combining methods. However, to validate final versions of systems further validation should be conducted using specialized software. © 2013 Published by Elsevier Ltd.

    Electronic screening and brief intervention (eSBI) apps demonstrate potential to reduce harmful drinking. However, low user engagement rates with eSBI reduce overall effectiveness of interventions. As "Digital Natives," young adults have high expectations of app quality. Ensuring that the design, content, and functionality of an eSBI app are acceptable to young adults is an integral stage to the development process. The objective of this study was to identify usability barriers and enablers for an app, BRANCH, targeting harmful drinking in young adults. The BRANCH app contains a drinking diary, alcohol reduction goal setting functions, normative drinking feedback, and information on risks and advice for cutting down. The app includes a social feature personalized to motivate cutting down and to promote engagement with a point-based system for usage. Three focus groups were conducted with 20 users who had tested the app for 1 week. A detailed thematic analysis was undertaken. The first theme, "Functionality" referred to how users wanted an easy-to-use interface, with minimum required user-input. Poor functionality was considered a major usability barrier. The second theme, "Design" described how an aesthetic with minimum text, clearly distinguishable tabs and buttons and appealing infographics was integral to the level of usability. The final theme, "Content" described how participants wanted all aspects of the app to be automatically personalized to them, as well as providing them with opportunities to personalize the app themselves, with increased options for social connectivity. There are high demands for apps such as BRANCH that target skilled technology users including young adults. Key areas to optimize eSBI app development that emerged from testing BRANCH with representative users include high-quality functionality, appealing aesthetics, and improved personalization. ©Joanna Milward, Paolo Deluca, Colin Drummond, Rod Watson, Jacklyn Dunne, Andreas Kimergård.

Bis kurz vor der Stadt Cajamarca im heutigen Peru schrieb Montúfar ein relativ unbekanntes Tagebuch zur Reise. Nach einem kurzen Ausflug in das Leben von Humboldts Begleiter steht im Zentrum der weiteren Ausführungen die Frage, ob sein Tagebuch ein anderes Licht auf Humboldt und speziell auf den Aufstiegsversuch wirft. Das läuft auf einen Vergleich der Tagebücher der beiden Reisegefährten hinaus und auf den Versuch, die scheinbaren Widersprüche aufzulösen.AbstractWhen Alexander von Humboldt left Quito in June 1802 in order to undertake the rest of his Latin-American trip of exploration, he was accompanied, aside from Aimé Bonpland, by Carlos Montúfar all the way back to Europe, including the attempt to scale the Chimborazo. Up to shortly before the city of Cajamarca in today’s Peru, Montúfar wrote an relatively unknown diary account of their travels. After a brief excursion into the life of Humboldt’s companion, the question is considered whether his diary sheds a different light on Humboldt and specifically on the mountain climb. That amounts to a comparison of the diaries of the two travel companions and to an attempt to explain the apparent contradictions.ResumenCuando Alexander von Humboldt salió de Quito en junio de 1802 para continuar con el resto de su viaje de exploración por la América Latina, fue acompañado por Carlos Montúfar además de Aimé Bonpland hasta que volvieron a Europa.

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Fritz Morgenthaler steht mit seinem Konzept der «Weichenstellungen » auf dem Boden von Freuds Postulat, wonach homosexuelle und heterosexuelle Orientierungen gleich erklärungsbedürftig sind. Allerdings können die «Weichenstellungen» weniger Hetero- oder Homosexualität per se erklären, sondern eher die verschiedenen Formen von Homo- und Heterosexualität in actu, wie sie in Fantasie und Verhalten gelebt werden. Mit Sexualität per se und Sexualität in actu sind zwei qualitativ verschiedene Gesichtspunkte benannt, unter denen Diskurse über manifeste und organisierte Sexualität sowie Perversionen mit Vorteil geführt werden. Dabei wird der Perversionsbegriff ausschliesslich der Sexualität in actu zugeordnet, welche als dialektische Einheit von sexuellen und nicht-sexuellen Funktionen aufgefasst wird. Pervers ist sexuelle Aktivität dann, wenn innerhalb dieser Einheit eine nicht-sexuelle Funktion die Priorität über die Triebbefriedigung hat. Sexualität per se bezeichnet Homosexualität, Heterosexualität, Fetischismus, Sadomasochismus, Pädophilie usw. als verschiedene erwachsene Sexualorganisationen – als hierarchische Organisation von Partialtrieben – auf «gleichberechtigter», entpathologisierter Ebene. Nachdem begründet wird, weshalb auch Judith Le Soldat den Grund zur Homosexualität per se anscheinend nicht gefunden hat und alle bisherigen psychogenetischen Herleitungen der verschiedenen erwachsenen Sexualorganisationen dieses Ziel verfehlen, empfiehlt sich ein grundsätzlicher Verzicht auf solche Erklärungsversuche – so wie es für die Heterosexualität per se meistens gehandhabt wird. Dagegen kann auf den u. a. von Robert Stoller verwendeten Begriff imprinting oder Prägung zurückgegriffen werden, welchen die Zürcher Analytiker Harold Lincke und Werner Fessler von jeglichem Biologismusverdacht befreit haben. Zum Schluss wird hervorgehoben, wie sehr Morgenthaler und Le Soldat mit ihrer Suche nach dem Grund zur

    Purpose: To optimize the MR sequences parameter for monitoring hyperthermic effects in the tissue during laser induced thermotherapy (LITT). Material and methods: Experimental studies were performed for the evaluation of MR-thermometry using a contrast-agent-water solution and a pig-liver. A T{sub 1}-weighted TurboFLASH sequence and a FLASH-3D sequence were used. The turboFLASH sequence was used with various T{sub 1} settings (between 100 and 1250 ms). MR findings were correlated with temperature measurements using a fluoride optical temperature measuring system in a distance of 1, 2, and 5 cm from the laser applicator. Results: Using the contrast-agent-water solution demonstrated the temperature sensitivity of both sequences. In vitro evaluations using pig liver demonstrated a near linear increase of signal versus increasing tissue temperatures in a distance of 1 cm to the tip of the laser applicator. Optimal visualization of the temperature effects was obtained using a T{sub 1} between 100 ms and 400 ms. Using the FLASH-2D sequence a signal loss was documented at a T{sub R} of 110 ms. Conclusion: MR-thermometry using sequentially TurboFLASH and FLASH-2D sequences allowed a non-invasive monitoring of the laser induced temperature changes. (orig.)

    Particularly during the spring and summer months the increase in insolation stimulates biological activity. Ultimately this activity inevitably increases the content in organic compounds of the seawater through dissimilation. Most of these compounds (e.g., humic acids, various lipids, peptides and polysaccharides) are able to complex heavy metals thus making them undetectable. In the case of electrochemical determination methods some of these organic compounds themselves react with the electrodes thus interfering with the intended measurement. In certain cases these interferences and superpositions can distort the results of an analysis by a factor of up 100. The intent of the present study was to destroy seawater organic compounds by means of a decomposition process which does not require the use of additional chemicals.

    Full Text Available Language is without any doubt a societal phenomenon, which is in many more ways related to space. While francophone, anglophone and Spanish geography have developed a kind of language geography or geolinguistics as a subdiscipline of geography, geographers in German-speaking countries pay some attention to this fact only within ethnic geography. The paper highlights some more important spatial aspects of language and proposes to regard language geography as a subdiscipline of cultural geography which has to co-operate closely with linguistics and history.

It is regarded as supercomplex and, thus, could not yet be systematically transformed in university didactics. Large scale conceptual terms such as justice, responsibility, participation, retinity, globality, and interculturality are at the core of the discussion – terms which run through basic texts, policy papers, and programmes as focal points of the idea of sustainability. With respect to the heuristic study Globality and Interculturality as Integral Elements of a Professional Education for a Sustainable Development (GInE, www.ibw.uni-hamburg.de/GInE, a didactic framework was designed which not only denotes exemplary problems and dilemmata but also puts up categories of reflection for a university didactics aiming at a professional teacher training.

    In this study, input variables for chemical transport models were compared from different meteorological drivers each with other and with the measured friction velocities in one place. Friction velocities are used as a measure of the mechanical turbulence, but are made available neither by numerical weather models nor routinely available observations: so they must either recalculate or estimated. In this study, friction velocities (u{sup *}), which is measured for years by the DWD in Lindenberg near Berlin, averaged over 30 minutes and have been made available to FU Berlin, compared with modeled values. The considered models are firstly the diagnostic interpolation model TRAMPER, on the other the prognostic models of the DWD COSMO-EU and the EZMWF. The boundary layer relevant parameters from the NWM were recalculated from the involved groups, which has been made for the COSMO-EU the one from the FU Berlin, the other from IfT in Leipzig. The boundary layer variables in the EZMWF model, however, were determined by TNO Netherlands. The measurements have shown that u{sup *} in the forest twice as high as above the meadow.

    Purpose: How much can the radiation dose be reduced for skull radiography by using digital luminescence radiography (DLR) compared to a conventional screen film system with a grid cassette? Methods and Materials: A skull phantom (3M) was X-rayed in anterior-posterior orientation using both a conventional screen film system with grid cassette and DLR (ADC-70, Agfa). The tube current time product (mAs) was diminished gradually while keeping the voltage constant. The surface entrance dose was measured by a sensor of Dosimax (Wellhoefer). Five investigators evaluated the images by characteristic and critical features, spatial resolution and contrast. Results: The surface entrance dose at 73 kV/22 mAs was 0,432 mGy in conventional screen film system and 0,435 mGy in DLR. The images could be evaluated very well down to an average dose of 71% (0,308 mGy; SD 0,050); sufficient images were obtained down to an average dose of 31% (0,136 mGy; SD 0,065). The resolution of the line pairs were reduced down to a 2 levels depending on the investigator. Contrast was assessed as being very good to sufficient. The acceptance of the postprocessed images (MUSICA-software) was individually different and resultde in an improvement of the assessment of bone structures an contrast in higher dose ranges only. Conclusion: For the sufficient assessment of a possible fracture/of paranasal sinuses/of measurement the skull the dose can be reduced to at least 56% (31%; SD 14,9%)/40% (27%; SD 9,3%)/18% (14%; SD 4,4%). Digital radiography allows question-referred exposure parameters with clearly reduced dose, so e.g. for fracture exclusion 73 kV/12,5 mAs and to skull measurement 73 kV/4 mAs. (orig.)

    In Germany, persons who are to be exposed to radiation for medical research purposes are protected by a licensing requirement. However, there are considerable uncertainties on the part of the applicants as to whether licensing by the competent Federal Office for Radiation Protection is necessary, and regarding the choice of application procedure. The article provides explanatory notes and practical assistance for applicants and an outlook on the forthcoming new regulations concerning the law on radiation protection of persons in the field of medical research. Questions and typical mistakes in the application process were identified and evaluated. The qualified physicians involved in a study are responsible for deciding whether a license is required for the intended application of radiation. The decision can be guided by answering the key question whether the study participants would undergo the same exposures regarding type and extent if they had not taken part in the study. When physicians are still unsure about their decision, they can seek the advisory service provided by the professional medical societies. Certain groups of people are particularly protected through the prohibition or restriction of radiation exposure. A simplified licensing procedure is used for a proportion of diagnostic procedures involving radiation when all related requirements are met; otherwise, the regular licensing procedure should be used. The new radiation protection law, which will enter into force on the 31st of december 2018, provides a notification procedure in addition to deadlines for both the notification and the licensing procedures. In the article, the authors consider how eligible studies involving applications of radiation that are legally not admissible at present may be feasible in the future, while still ensuring a high protection level for study participants.

    To increase the use of pulse oximetry by capitalise on the wide availability of mobile phones, we have designed, developed and evaluated a prototype pulse oximeter interfaced to a mobile phone. Usability of this Phone Oximeter was tested as part of a rapid prototyping process. Phase 1 of the study (20 subjects) was performed in Canada. Users performed 23 tasks, while thinking aloud. Time for completion of tasks and analysis of user response to a mobile phone usability questionnaire were used to evaluate usability. Five interface improvements were made to the prototype before evaluation in Phase 2 (15 subjects) in Uganda. The lack of previous pulse oximetry experience and mobile phone use increased median (IQR [range]) time taken to perform tasks from 219 (160-247 [118-274]) s in Phase 1 to 228 (151-501 [111-2661]) s in Phase 2. User feedback was positive and overall usability high (Phase 1--82%, Phase 2--78%). Anaesthesia © 2012 The Association of Anaesthetists of Great Britain and Ireland.

    For many years the reestablishment of communication for people with severe motor paralysis has been in the focus of brain-computer interface (BCI) research. Recently applications for entertainment have also been developed. Brain Painting allows the user creative expression through painting pictures. The second, revised prototype of the BCI Brain Painting application was evaluated in its target function - free painting - and compared to the P300 spelling application by four end users with severe disabilities. According to the International Organization for Standardization (ISO), usability was evaluated in terms of effectiveness (accuracy), efficiency (information transfer rate (ITR)), utility metric, subjective workload (National Aeronautics and Space Administration Task Load Index (NASA TLX)) and user satisfaction (Quebec User Evaluation of Satisfaction with assistive Technology (QUEST) 2.0 and Assistive Technology Device Predisposition Assessment (ATD PA), Device Form). The results revealed high performance levels (M≥80% accuracy) in the free painting and the copy painting conditions, ITRs (4.47-6.65bits/min) comparable to other P300 applications and only low to moderate workload levels (5-49 of 100), thereby proving that the complex task of free painting did neither impair performance nor impose insurmountable workload. Users were satisfied with the BCI Brain Painting application. Main obstacles for use in daily life were the system operability and the EEG cap, particularly the need of extensive support for adjustment. The P300 Brain Painting application can be operated with high effectiveness and efficiency. End users with severe motor paralysis would like to use the application in daily life. User-friendliness, specifically ease of use, is a mandatory necessity when bringing BCI to end users. Early and active involvement of users and iterative user-centered evaluation enable developers to work toward this goal. Copyright © 2013 Elsevier B.V. All rights reserved.

    Patients who receive rehabilitation after hip replacement surgery are shown to have increased muscle strength and better functional performance. However, traditional physiotherapy is often tedious and leads to poor adherence. Exercise games, provide ways for increasing the engagement of elderly patients and increase the uptake of rehabilitation exercises. The objective of this study was to evaluate Fietsgame (Dutch for cycling game), which translates existing rehabilitation exercises into fun exercise games. The system connects exercise games with a patient's personal record and a therapist interface by an Internet of Things server. Thus, both the patient and physiotherapist can monitor the patient's medical status. This paper describes a pilot study that evaluates the usability of the Fietsgame. The study was conducted in a rehabilitation center with 9 participants, including 2 physiotherapists and 7 patients. The patients were asked to play 6 exercise games, each lasting about 5 min, under the guidance of a physiotherapist. The mean age of the patients was 74.57 years (standard deviation [SD] 8.28); all the patients were in the recovery process after hip surgery. Surveys were developed to quantitatively measure the usability factors, including presence, enjoyment, pain, exertion, and technology acceptance. Comments on advantages and suggested improvements of our game system provided by the physiotherapists and patients were summarized and their implications were discussed. The results showed that after successfully playing the games, 75% to 100% of the patients experienced high levels of enjoyment in all the games except the squats game. Patients reported the highest level of exertion in squats when compared with other exercise games. Lunges resulted in the highest dropout rate (43%) due to interference with the Kinect v2 from support chairs. All the patients (100%) found the game system useful and easy to use, felt that it would be a useful tool in their further rehabilitation, and expressed that they would like to use the game in the future. The therapists indicated that the exercise games highly meet the criteria of motor rehabilitation, and they intend to continue using the game as part of their rehabilitation treatment of patients. Comments from the patients and physiotherapists suggest that real-time corrective feedback when patients perform the exercises wrongly and a more personalized user interface with options for increasing or decreasing cognitive load are needed. The results suggest that Fietsgame can be used as an alternative tool to traditional motor rehabilitation for patients with hip surgery. Lunges and squats are found to be more beneficial for patients who have relatively better balance skills. A follow-up randomized controlled study will be conducted to test the effectiveness of the Fietsgame to investigate how motivating it is over a longer period of time. ©Yun Ling, Louis P Ter Meer, Zerrin Yumak, Remco C Veltkamp.

    Shared decision making (SMD) related to treatment and rehabilitation is considered a central component in recovery-oriented practice. Although decision aids are regarded as an essential component for successfully implementing SDM, these aids are often lacking within psychiatric services. The aim of this study was to use a participatory design to facilitate the development of a user-generated, web-based decision aid for individuals receiving psychiatric services. The results of this effort as well as the lessons learned during the development and usability processes are reported. The participatory design included 4 iterative cycles of development. Various qualitative methods for data collection were used with potential end users participating as informants in focus group and individual interviews and as usability and pilot testers. Interviewing and testing identified usability problems that then led to refinements and making the subsequent prototypes increasingly user-friendly and relevant. In each phase of the process, feedback from potential end-users provided guidance in developing the formation of the web-based decision aid that strengthens the position of users by integrating access to information regarding alternative supports, interactivity between staff and users, and user preferences as a continual focus in the tool. This web-based decision aid has the potential to strengthen service users' experience of self-efficacy and control as well as provide staff access to user knowledge and preferences. Studies employing participatory models focusing on usability have potential to significantly contribute to the development and implementation of tools that reflect user perspectives.

    This article follows to an essay in the ZNER of 2011 (S. 121 et seq.) for the first Joint Practical Guide of the Federal Network Agency (BNetzA) and Federal Cartel Office (FCO) from the year 2010, in which the authors had attested authorities a good ''step towards to more competition ''. In the essay is examined and shown that the Joint practical guide from the year 2010 this target could meet and what effect the now in its second edition newly revised guidelines on competition to distribution networks may have. The revision of the guidelines will be given to municipalities further action assistance to the hand, but - with few exceptions - only reproduces the jurisprudence of the staked legal framework. One proposed solution for the more diverse existing problems remains undone, whereas new problem areas are put up in several places. Nevertheless, the will of the authorities is to recognize, to avoid legal problems in the concession process and net acquisitions from the outset. [German] Dieser Beitrag knuepft an einen Aufsatz in der ZNER 2011 (S. 121 ff.) zum ersten Gemeinsamen Leitfaden von Bundesnetzagentur (BNetzA) und Bundeskartellamt (BKartA) aus dem Jahre 2010 an, in dem die Autoren den Behoerden einen richtigen ''Schritt hin zu mehr Wettbewerb'' attestiert hatten. In der Abhandlung wird untersucht und dargestellt, ob der Gemeinsame Leitfaden aus dem Jahr 2010 diesem Ziel gerecht werden konnte und welche Auswirkungen der nunmehr in der zweiten Auflage neu ueberarbeitete Leitfaden auf den Wettbewerb um Verteilnetze haben kann. Die Ueberarbeitung des Leitfadens wird den Kommunen eine weitere Handlungshilfe an die Hand gegeben, die aber - bis auf wenige Ausnahmen - den durch die Rechtsprechung abgesteckten Rechtsrahmen nur wiedergibt.

    Full Text Available [english] Objective: The present questionnaire survey investigated student reception of problem-based learning (PBL in the orthodontic curriculum with regard to acceptance, sense of purpose and motivation, knowledge and understanding, as well as tutorial support.Methods: Over a period of two terms, we compared two different didactic methods (PBL and short presentations by randomizing the participants of a course on orthodontic diagnostics into two different groups, who inversed methods after the first term. Results: The two student groups did not show any significant differences with regard to assessments or examination performance. Therefore, acceptance of the PBL concept seems to be mainly associated with the motivation of individuals to use this method. The higher the motivation, the more positive is the attitude towards the PBL concept. Students seem to work more constructively and efficiently with PBL if they can judge the concept meaningful for themselves.Conclusion: In consideration of the relevant literature and the present results, PBL can be principally integrated into the dental curriculum as a method of learning. However, student motivation is vital to learning success.[german] Ziel: In der vorliegenden Fragebogenstudie wurde die studentische Rezeption des problemorientierten Lernens (POL im Curriculum der Kieferorthopädie hinsichtlich Akzeptanz, Sinn/Motivation, Wissen/Verstehen und tutorieller Unterstützung untersucht.

  2. Kontingenz, Redundanz, Transzendenz? - Zum Gerechtigkeitsbegriff Niklas Luhmanns

    Directory of Open Access Journals (Sweden)

    Moritz Renner

    2008-11-01

    Full Text Available Niklas Luhmanns systemtheoretische Rekonstruktion der „Kontingenzformel Gerechtigkeit“ gilt als der anspruchsvollste Versuch einer positivistischen Gerechtigkeitstheorie. Der Versuch zielt darauf ab, den Begriff der Gerechtigkeit aus den Operationen des Rechtssystems selbst zu entwickeln und setzt an der formalen Konsistenz rechtlicher Entscheidungen an. Vielfach ist Luhmanns Theorie daher ihr vermeintlicher Verlust der Einzelfallgerechtigkeit vorgeworfen worden. Neuere, an der Dekonstruktion orientierte Luhmann-Interpretationen begegnen diesem Einwand, indem sie die Offenlegung der Selbstwidersprüche des selbstreferentiellen Rechtssystems als eine Form der Rechtskritik auffassen, welche dem Rechtsdiskurs zwar immanent bleibt, zugleich aber auf die Möglichkeit seiner Transzendierung verweist.

    2014-09-01

    Full Text Available This paper investigates the syntactic behaviour of adverbial clauses in contemporary German and Italian. It focuses on three main questions: (i How many degrees of syntactic integration of adverbial clauses are there to be distinguished by an adequate grammatical description of the two languages? (ii Which linear and hierarchical positions in the structure of the matrix sentence can be occupied by adverbial clauses? (iii Which is the empirical distribution of adverbial clauses introduced by the conjunctions als, während, wenn, obwohl and weil in German, as well as quando, mentre, se, sebbene and perché in Italian? Responding to question (i, a distinction is drawn between strongly integrated, weakly integrated and syntactically disintegrated adverbial clauses. There are further degrees on the gradient of syntactic integration, which are not examined in this paper. Responding to question (ii, eight classes of structural positions in the matrix sentence are identified that can be occupied by adverbial clauses. Five of them are positions of syntactic integration, three are positions of disintegration. Responding to question (iii, the distribution of the ten classes of adverbial clauses is described on the basis of a corpus of internet data. Strongly integrated, weakly integrated and disintegrated adverbial clauses show clearly different distributions within the structure of the matrix sentence. Also the semantic classes of adverbial clauses (temporal, adversative, conditional, concessive, causal are distributed differently.

    Within the framework of periodic safety inspection of the Gundremmingen power station (RWE-Bayernwerk - KRB II), the load collectives used for the design of safety-relevant systems and components were checked for their consistency with latest updates of the design basis. It was found that there was no analytical information or study available describing a particular process and its effects, namely switch-off of the high-pressure feedwater pump of the emergency core cooling system. The paper reports the work performed for closing the gap, including preparatory analyses, accompanying measures such as vibration measurements during plant shut-down, as well as the preparation and performance of the in-situ test. The experimental results and the comparative evaluation of calculated and experimental data are presented.

    In long-lived technical systems, the main challenge is in preserving knowledge on all technical aspects throughout the plant life as several generations of engineers are involved from projecting to decommissioning. A technical support organisation has access to knowledge on safety requirements and their development with time, relevant damage cases both in Germany and abroad, research projects and analyses as well as expert documentations. A modern working environment enables fast access to, and combination of, distributed parts of knowledge provided that some prestructuring is ensured. The contribution presents an exemplary information system of GRS, whose elements may be of interest to other organisations as well. [German] Fuer technische Anlagen mit langen Lebenszeiten ist es eine besondere Herausforderung, das erforderliche Wissen zu allen technischen Sachverhalten jederzeit verfuegbar zu haben. Von der Projektierung bis zum Betriebsende einer Anlage sind mehrere Generationen von Ingenieuren mit den jeweiligen Sachverhalten befasst. Fuer eine Sachverstaendigenorganisation stehen Kenntnisse zu den sicherheitstechnischen Anforderungen und deren zeitlicher Entwicklung, relevanten Schadensereignissen im In- und Ausland, Erkenntnisse aus Forschungsvorhaben und Analysen sowie die Verfuegbarkeit des weiteren dokumentierten Fachwissens und technischer Experten im Vordergrund. Die moderne Arbeitsumgebung erlaubt heute ein schnelles Auffinden und Zusammenfuehren der vorhandenen Wissensbausteine.

A total of 21 users of the internet participated in three focus group sessions. 17 participants were given a series of health questions and observed in a usability laboratory setting while retrieving health information from the web; this was followed by in-depth interviews. Heidelberg, Germany. Although their search technique was often suboptimal, internet users successfully found health information to answer questions in an average of 5 minutes 42 seconds (median 4 minutes 18 seconds) per question. Participants in focus groups said that when assessing the credibility of a website they primarily looked for the source, a professional design, a scientific or official touch, language, and ease of use. However, in the observational study, no participants checked any "about us" sections of websites, disclaimers, or disclosure statements. In the post-search interviews, it emerged that very few participants had noticed and remembered which websites they had retrieved information from. Further observational studies are needed to design and evaluate educational and technological innovations for guiding consumers to high quality health information on the web.

    To evaluate usability and pain iconography of the Iconic Pain Assessment Tool Version 2 (IPAT2), a self-report instrument that combines word descriptors and representative images (icons) to assess pain quality, intensity, and location, among adults and adolescents with arthritis. Adults with inflammatory arthritis and adolescents with juvenile idiopathic arthritis partook in a single, semistructured, audio-recorded interview to evaluate: (1) the concreteness (object representativeness) and semantic distance (pain representativeness) of the IPAT2 iconography; (2) participants' current pain; and (3) perceptions and likes/dislikes of the IPAT2. Quantitative data were summarized descriptively and a line-by-line coding analysis identified key concepts from interview transcripts. The criterion for icon acceptability was mean and median ratings ≥5.0 for concreteness, semantic distance, and satisfaction for describing arthritis pain. The sample was comprised of 15 adults (87% female, mean 57 y) and 15 adolescents (67% female, mean age 15 y). The IPAT2 was reported to be easy to use and understand, well liked, quick to complete, and perceived as potentially valuable for communicating arthritis pain to health care providers. The median time needed to complete a single pain record, after 5-minute demonstration, was 2.3 minutes and 1.4 minutes for the adults and adolescents, respectively. All pain quality icons met or exceeded the criterion for acceptability. All a priori objectives for the IPAT2 were achieved in this sample of rheumatology outpatients. With its unique blend of pain quality descriptors and representative images, the IPAT2 may importantly aid the assessment of pain in adults and adolescents with arthritis.

    We examined the usability of smartphones for accessing a web-based e-Diary for self-monitoring symptoms in children and adolescents with sickle cell disease (SCD). One group of participants (n = 10; mean age, 13.1 ± 2.4 y; 5 M; 5 F) responded to questions using precompleted paper-based measures. A second group (n = 21; mean age, 13.4 ± 2.4 y; 10 M; 11 F) responded based on pain and symptoms they experienced over the previous 12 hours. The e-Diary was completed with at least 80% accuracy when compared to paper-based measures. Symptoms experienced over the previous 12 hours included feeling tired (33.3%), headache (28.6%), coughing (23.8%), lack of energy/fatigue (19.0%), yellowing of the eyes (19.0%), pallor (19.0%), irritability (19.0%), stiffness in joints (19.0%), general weakness (14.3%), and pain (14.3%), rating on average as 2.0 ± 1.7 (on 0 to 10 scale). Overall, sleep was good (8.1 ± 1.4 on the 0 to 10 scale). In conclusion, children with SCD were able to use smartphones to access a web-based e-Diary for reporting pain and symptoms. Smartphones may improve self-reporting of symptoms and communication between patients and their health care providers, who may consequently be able to improve pain and symptom management in children and adolescents with SCD in a timely manner.

    To develop methods for rapid and simultaneous design, testing, and management of multiple clinical decision support (CDS) features to aid nurse decision-making. We used quota sampling, think-aloud and cognitive interviews, and deductive and inductive coding of synchronized audio video data and archival libraries. Our methods and organizational tools allowed us to rapidly improve the usability, understandability, and usefulness of CDS in a generalizable sample of practicing nurses. The method outlined allows the rapid integration of nursing terminology based electronic health record data into routine workflow and holds strong potential for improving patient outcomes. The methods and organizational tools for development of multiple CDS system features can be used to translate knowledge into practice. © 2016 NANDA International, Inc.

    The project 'Planning geological underground repositories: Communicating with society', financed by the Swiss Federal Office for Energy, aimed at identifying basic principles for an appropriate information and communication strategy in the process of finding an underground site to store radioactive wastes. The topic concerns an issue increasingly discussed in modern societies: How to improve the dialogue between science, infrastructure operators, public authorities, groups in civil society and the population to answer complex problems? Against this background, in the project the following questions were taken into account: (i) How can the dialogue between science, politics, economy, and the (non-)organised public be arranged appropriately? Which principles are to be considered in organising this process? How can distrust within the population be reduced and confidence in authorities and scientific expertise be increased? (ii) How can society be integrated in the process of decision-making so that this process is perceived as comprehensible, acceptable and legitimate? To answer these questions, an analysis method based on scientific theory and methodology was developed, which compares national participation and communication processes in finding underground storage sites in selected countries. Case studies have been carried out in Germany, Sweden, Belgium, and Switzerland. By using specific criteria to evaluate communication processes, the strong points as well as the drawbacks of the country-specific concepts of information, communication and participation have been analysed in a comparing dimension. By taking into account the outcomes, prototypical scenarios have been deduced that can serve as a basis for compiling a reference catalogue of measures, which is meant to support the Swiss communication strategy in the finding of an appropriate site for a nuclear waste repository. Following conclusions can be drawn from the international comparison: (i) Open and transparent communication builds-up trust: information must be accessible to everyone; experts have to be understandable for everyone. (ii) Actor roles have to be communicated: too many communicators and/or not clearly defined roles diminish credibility. - Communication on regional and local levels has priority: communicators are persons, not anonymous organisations; however, do not forget national communication. (iii) Best communication is public participation: it builds up expertise and ability to judge. (iv) Communication needs sufficient and fair distributed resources. The empirical results of this research project have been translated into a separate brochure with guidelines for the communication throughout the oncoming site selection process in Switzerland.

    As part of the promotional program AUTONOMIK of the Federal Ministry of Economics and Technology (Berlin, Federal Republic of Germany) a consortium of nine project partners developed a prototype of an autonomous mobile robot looking for gas leaks in extended industrial equipment. The autonomous mobility of the system for any systems was implemented using different types of sensors for self-localization and navigation. The tele-operation enables a manual intervention in the process. The robot performs inspection tasks in industrial plants by means of video technology and remote gas measurement technology without driving into the possible risk areas and without the presence of humans. The robot can be used for routine inspections of facilities or for the targeted inspection of specific plant components. Thanks to the remote sensing technique also plant components can be inspected which are difficult to be inspected due to their limited accessibility by conventional measurement techniques.

    From 1990 the reduction of lignite mining on the territory of the German Democratic Republic (GDR) led to the closure of plants for the production and processing of lignite. This entailed a dramatic demand of redevelopment and transformation of former mining and industrial areas of lignite industry and the creation of the industrial branch of remediation of post-lignite-mining areas, for which suitable structures of management and financing had to be found. The target of these endeavours is the creation of multifunctional to follow former surface mining areas. Ecological and security criteria play an eminent part in this process. Stabilising slopes, recultivation, rehabilitation of a balanced water regime and the elimination of dangers emanating from groundwater and soil contamination by earlier industrial use have particular priority. Recultivation requires scientific preparation and surveillance. Deficits are discussed that have led to the invitation of tenders for a promotion initiative and resulted in the implementation of a number of research projects. This publication deals with the presentation of the tasks and research approaches as well as the description and evaluation of results with the view of their applicability. (orig.)

    So far, municipal transport planning and policy have not really resulted in pioneering concepts for solving problems arising from the transport issue common to all cities. Even individual promising approaches, which mostly relate to singular aspects of municipal transport policy, cannot obscure the fact that the routines of transport planning obviate innovative impulses. Even the research project's two exemplary municipalities, Freiburg and Schwerin, are a long way from having attained a mobility beneficial to the community (as reflected in a report on these cities' transport situation in the annex). In both there are elements of motor-vehicle-oriented planning and transport policy, but also, in part, distinct clues to a decline in car orientation and to the furtherance of alternative, environmentally compatible means of transport. The present guideline wants to open up new perspectives and give concerned planners impulses. It summarizes results from the research project 'Compatibility of urban mobility' and describes new ideas and paradigms in municipal transport planning and policy. (orig.) [German] Kommunale Verkehrsplanung und -politik hat bisher nicht zu wirklich zukunftsweisenden Loesungsentwuerfen der flaechendeckend festzustellenden Verkehrsproblematik in den Staedten gefuehrt.

Auch die beiden Modellkommunen des Forschungsprojektes, Freiburg und Schwerin, sind um einiges von dem Ziel der Stadtvertraeglichen Mobilitaet entfernt (s. verkehrliche Zustandsbeschreibung im Anhang). In beiden Staedten finden sich Elemente der autoorientierten Planung und Verkehrspolitik, aber auch zum Teil deutliche Hinweise des Zurueckdraengens der Autoorientierung und der Foerderung der umweltvertraeglichen

Die rekonstruktive Jugendstudie auf der Grundlage der «dokumentarischen Methode» zielt darauf, die digitale Handlungspraxis Jugendlicher, insbes. aus Haupt- und Realschulmilieus, schulform- und geschlechtspezifisch zu generieren; d. h. die Untersuchung ist an der Schnittstelle von Jugend- und Schulforschung zu verorten. Ein zentrales Ziel des Forschungsprojekts besteht darin, Erkenntnisse, die über die medialen Orientierungen der Jugendlichen gewonnen werden, in allgemeindidaktische Bildungskonzepte für die Lehreraus- und -fortbildung überzuführen. Im Zentrum des Projekts steht also die bildungs- bzw. professionstheoretische Frage, der auch in unserem Beitrag nachgegangen werden soll, wie eine theoriegestützte schulformbezogene Lehrerbildung aussehen könnte, um Unterricht so zu gestalten, dass Schüler/innen ein (selbst-reflexives Verhältnis zu den neuen Medien aufbauen können. Hierbei sollen erstens Ergebnisse unseres Projekts kurz dargestellt und auf einen Befund fokussiert werden: die zentrale Bedeutung der digitalen Medien im Leben von Haupt- und Realschüler/innen ausserhalb der Schule und ein daran geknüpfter «digitaler Pseudo-Spezialistenhabitus» von Jungen, insbesondere im Hauptschulbereich. Vor diesem Hintergrund soll zweitens der Kern pädagogischen Handelns genauer beleuchtet und Ansätze eines heuristischen Modells für die Lehreraus- und -fortbildung diskutiert werden, das beansprucht, zu einer geschlechterreflexiven Medienbildung beizutragen.

Das Teilprojekt `Biologische Dosimetrie` befasst sich einerseits mit der Frage, ob die Bestimmung von Mikronuklei in peripheren Lymphozyten auch noch mehrere Jahre nach der Reaktorkatastrophe eine Aussage zur Strahlenexposition erlaubt. Ausserdem wurde geprueft, ob Mikronuklei geeignet sind, den Verlauf der Radioiodtherapie im Rahmen der Behandlung von Schilddruesentumoren zu verfolgen. Weiterhin wurde an einer im Vergleich zur vorliegenden Literatur grossen Zahl von kindlichen Tumoren geprueft, ob es spezifische Mutationsmuster in Tumor-Suppressorgenen (p-53) in Schilddruesentumoren gibt, die zum Nachweis der Strahleninduktion dieser Tumoren geeignet sich. Das Teilprojekt `Retrospektive Dosimetrie und Risikoanalyse` befasste sich vor allem mit der Frage, ob die Vermutung zutrifft, dass die Freisetzung von I-131 bei der Reaktorkatastrophe zur erhoehten Inzidenz von Schilddruesenkarzinomen bei Kindern gefuehrt hat.

    Science.gov (United States)

    Sommer, Ralf J.

    Die moderne Evolutionsbiologie hat ihren Ursprung in den Arbeiten von Charles Darwin und Alfred Wallace (Darwin 1963). Der gemeinsame Ausgangspunkt des Evolutionsgedanken ist dabei die Beobachtung, dass die biologische Welt nicht konstant ist. Biologische Systeme und alle darin lebenden Organismen unterliegen über längere Zeiträume hinweg einer stetigen Veränderung. Diese grundlegende Eigenschaft biologischer Systeme macht die Biologie zu einer historischen Wissenschaft und stellt einen wichtigen Gegensatz zu großen Teilen der Physik dar. Obwohl die Aussage von der Veränderlichkeit der Arten heute trivial klingt, war sie im 19. Jahrhundert eine Revolution, da die Konstanz der Arten und der Welt eine vorherrschende Stellung im damaligen Weltbild hatte (Amundson 2005).

    Kaum eine Branche hat in den letzten zehn Jahren einen tiefgreifenderen Wandel erfahren als die Energiewirtschaft. Einstmals geprägt durch Großkonzerne, die flächendeckend alle Formen von Energiedienstleistungen erbracht haben, stellt sich heute eine gänzlich veränderte Landschaft dar. Nicht nur das es heute eine Vielzahl von Erzeugern gibt, die zunehmend dezentral aufgestellt sind, auch die klassischen Marktrollen wechseln: Erzeuger werden zu Händlern, Verbraucher werden zu Erzeugern. Darüber hinaus drängen heute neue, vormals branchenfremde, Marktteilnehmer in die Energiewirtschaft. Leicht nachzuvollziehen, dass es eine neue Art der Kommunikation braucht. Ziel ist alle Akteure zu vernetzen, um so neuartige Geschäftsmodelle zu ermöglichen. Das Internet of Things (IoT) und die Serviceplattformen bieten hierzu die geeignete Grundlage und Lösungen für neue und zukünftige Prozesse in der Energiebranche. Hierbei stehen auch Themen, wie Big Data, Datenformate, Datennutzung und -sicherheit im Fokus.

Presumably, this silicene would be even more appropriate than graphene for high-power electronics. But now physicists succeeded in the production of this material in the laboratory.

    Full Text Available Gerechtigkeit ist eine der Voraussetzungen für Nachhaltigkeit. Eine der wichtigsten Aufgaben der Bildung ist deshalb die Vermittlung von Gerechtigkeitsstandards. Was aber ist Gerechtigkeit? Unter Bezugnahme auf philosophische Betrachtungen sowie auf Forschungsergebnisse aus Soziologie, Sozialpsychologie und Neurobiologie kommt die vorliegende Untersuchung zu dem Ergebnis, das Gerechtigkeit eine Synthese aus Verstand, Vernunft und Gefühl ist, die sich auf die Freiheitsbeschränkung individuellen Handelns bezieht. Während uns Verstand und Vernunft abstrakt bleiben, geht der eigentliche Handlungsimpuls vom Gefühl aus. In den aktuellen Bildungszielen spielen Gefühle als motivationale Grundlage gerechten Handelns praktisch keine Rolle. Dem gegenüber dominiert die Ausbildung instrumentellen Verstandes. Welche fatalen Folgen eine Überbetonung der Verstandesbildung gegenüber Vernunft und Gefühl hat, zeigen die Arbeiten der Aufklärungskritik. Die Verfasser kommen zu dem Schluss, dass Bildung, die dem Leitbild der Nachhaltigkeit gerecht wird, verstärkt auf Vernunft und Gefühl setzen sollte.“If we do not act, millions of people will suffer.” The relationship between sustainability, justice and education. Justice is a precondition for sustainability. Therefore one of the most important tasks of education is the communication of standards of justice. But what is meant by justice? With regard to philosophical reflections as well as results of the latest research in the fields of sociology, social psychology and neurobiology, this paper concludes that justice is a synthesis of understanding, reason and compassion. This synthesis refers to the restriction of freedom of individual action. Whereas our understanding and reason remains abstract, the real impulse of action comes from compassion. Compassion as a motivational basis plays no role in current educational goals. In contrast education is dominated by instrumental understanding. The fatal consequences of overemphasizing education of understanding versus reason and compassion can be seen in works on the criticism of enlightenment. The authors of this paper conclude that education, which meets the model of sustainability, must emphasize reason and compassion.

    Full Text Available In modern postwar orders (and disorders the concept of democratic peace prescribes that losing parties remember defeat and accept blame in order to redeem themselves and receive amnesty. In addition, the winning side’s position is to be accepted as rightful, morally just, and inherently peaceable. However, the historian Reinhart Koselleck remarks that throughout history succeeding postwar transitions were creatively framed through three alternatives: first, noting down what really has happened (documentation; second, embedding war experience into larger historical frameworks in order to integrate and minimize the defeat (contextualization; and, third, denying the defeat by rewriting it (annihilation/reinterpretation. But groups who are likely to be defeated are already able to anticipate the modern constrictions on these alternatives during wartime. Our thesis is that the recent limiting of options for postwar arrangements is one key factor for both the emerging permanence of asymmetric, or so-called ‘new wars’, and the multitude of notoriously unstable postwar architectures.

    The Strengthening and Stretching for Rheumatoid Arthritis of the Hand (SARAH) is a tailored, progressive exercise program for people having difficulties with wrist and hand function due to rheumatoid arthritis (RA). The program was evaluated in a large-scale clinical trial and was found to improve hand function, was safe to deliver, and was cost-effective. These findings led to the SARAH program being recommended in the UK National Institute for Health and Care Excellence guidelines for the management of adults with RA. To facilitate the uptake of this evidence-based program by clinicians, we proposed a Web-based training program for SARAH (iSARAH) to educate and train physiotherapists and occupational therapists on delivering the SARAH program in their practice. The overall iSARAH implementation project was guided by the 5 phases of the analysis, design, development, implementation, and evaluation (ADDIE) system design model. The objective of our study was to conduct the first 3 phases of the model in the development of the iSARAH project. Following publication of the trial, the SARAH program materials were made available to therapists to download from the trial website for use in clinical practice. A total of 35 therapists who downloaded these materials completed an online survey to provide feedback on practice trends in prescribing hand exercises for people with RA, perceived barriers and facilitators to using the SARAH program in clinical practice, and their preferences for the content and Web features of iSARAH. The development and design of iSARAH were further guided by a team of multidisciplinary health professionals (n=17) who took part in a half-day development meeting. We developed the preliminary version of iSARAH and tested it among therapists (n=10) to identify and rectify usability issues and to produce the final version. The major recommendations made by therapists and the multidisciplinary team were having a simple Web design and layout, clear exercise pictures and videos, and compatibility of iSARAH on various browsers and devices. We rectified all usability issues in the preliminary version to develop the final version of iSARAH, which included 4 short modules and additional sections on self-assessment, frequently asked questions, and a resource library. The use of the ADDIE design model and engagement of end users in the development and evaluation phases have rendered iSARAH a convenient, easy-to-use, and effective Web-based learning resource for therapists on how to deliver the SARAH program. There is also huge potential for adapting iSARAH across different cultures and languages, thus opening more opportunities for wider uptake and application of the SARAH program into practice. ©Cynthia Swarnalatha Srikesavan, Esther Williamson, Lucy Eldridge, Peter Heine, Jo Adams, Tim Cranston, Sarah E Lamb.

    Full Text Available The publication stemming from the research project “Governing Prostitution” at the University of Leipzig approaches the question as to which problems of definition, categorization, and inventories of knowledge local administrators in Germany, Poland, and the Czech Republic use as a basis for regulating prostitution. The study shows that law not only implements partially autonomous governing acts but also produces them. The monograph enters into uncharted territory with its local focus on the regulation of prostitution as its subject and its state-based ethnographical approach. A little more information as to methodology as well as a more explicit take on the theoretical concepts in the format of the empirical materials would have been desirable.Die aus dem Forschungsprojekt ‚Verwaltung der Prostitution‘ an der Universität Leipzig heraus entstandene Publikation geht der Frage nach, welche Problemdefinitionen, Kategorisierungen und Wissensbestände lokale Verwaltungsakteure/-innen in Deutschland, Polen und Tschechien der Prostitutionsregulierung zugrunde legen. Die Studie zeigt, dass teilautonomes Verwaltungshandeln Recht nicht nur umsetzt, sondern auch produziert. Durch den Fokus auf die lokale Ebene der Prostitutionsregulierung und durch den staatsethnographischen Zugang ist die Monographie in zweierlei Hinsicht innovativ. Lediglich etwas mehr Informationen zum methodischen Vorgehen sowie ein expliziteres Aufgreifen der theoretischen Konzepte bei der Aufbereitung des empirischen Materials wären wünschenswert gewesen.

    Network monitoring of extensive water distribution systems as you can find in rural areas causes high costs. Therefore a current research project tries to find cost savings by using automatic meter reading of main flow meters within the network. The project focuses on improving leakage control as well as optimizing rehabilitation investments. By operation of a pilot plant significant potentialities for cost savings already could be identified. Additionally the calculation of the optimal time of rehabilitation shows that automatic meter reading is able to reduce investment costs. For the calculation of the costs the research team developed a software that supports the user in this decision making process. (orig.) [German] In grossraeumigen Wasserversorgungsnetzen, wie sie vor allem im laendlichen Raum anzutreffen sind, ist die Netzueberwachung mit erheblichem Aufwand verbunden. In einem laufenden Forschungsvorhaben wird untersucht, inwieweit sich Einsparungen durch Einsatz von fernablesbaren Grosswasserzaehlern realisieren lassen. Im Zentrum steht dabei die Verbesserung der Leckageueberwachung sowie eine Optimierung der Reinvestitionsplanung. Anhand ausgewaehlter Untersuchungsgebiete des beteiligten Wasserversorgers konnten bereits eindeutige Einsparpotenziale im Netz- und Leckagenmanagement durch den Einsatz der Fernablesung nachgewiesen werden. Auch die Berechnung des betriebswirtschaftlich optimalen Reinvestitionszeitpunkts laesst darauf schliessen, dass der Einsatz der Fernablesung zu einer Kostenreduktion fuehrt. Zur Berechnung der Kosten wurde eine Software entwickelt, die den Anwender bei seiner Entscheidungsfindung unterstuetzt. (orig.)

    The goal of the research was the development of concepts that support ultra low emission concepts for vehicles with combustion engines. This has been done in the 4 subprojects 'Increase of mass transfer', 'Catalyst isolation', 'Reduction of thermal mass' and 'Homogenization of flow distribution'. In the fifth subproject 'catalyst design' the gained experiences should be used to realize the achieved results for practical applications. Phases of the project: Literature investigation - theoretical consideration and interpretation - investigations on favoured variants - durability tests - study of parameters of manufacturing process - emission tests. The gained experiences were slipped in several products that can be realized in serial production. To be mentioned: (a) The TS-Designs and the LS-Design (see subproject A), (b) the HD-Design (see subproject B, C, E), (c) and the mixing device (see subproject D). Additional know-how was gained in subproject D that was used to work out the PM-Design in a separate developement project. These substrates can be used to reduce soot emissions in vehicles with diesel engines. (orig.)

    The version 3 of the procedure guideline for radioiodine test is an update of the guideline previously published in 2003. The procedure guideline discusses the pros and cons of a single measurement or of repeated measurements of the iodine-131 uptake and their optimal timing. Different formulas are described when one, two or three values of the radioiodine kinetic are available. The probe with a sodium-iodine crystal, alternatively or additionally the gamma camera using the ROI-technique are instrumentations for the measurement of iodine-131 uptake. A possible source of error is an inappropriate measurement (sonography) of the target volume. The patients' preparation includes the withdrawal of antithyroid drugs 2-3 days before radioiodine administration. The patient has to avoid iodine-containing medication and the possibility of additives of iodine in vitamin- and electrolyte-supplementation has to be considered. (orig.)

In contemporaneity the concept of Bildung even at University has been identified more and more with labor. The synonymous use of both terms stands in contradiction to the historic meaning of Bildung at its first occurrence in ancient Greek. The original characterization of Bildung which decidedly excluded any kind of work is no longer taken into consideration. The article reflects on the problematic loss of the historic consciousness of the difference between Bildung and labor and on the debatable consequences resulting in a constrictive and pauperizing development of Theory of Education.

    The ATLAS experiment at the future Large Hadron Collider at CERN uses a silicon pixel detector as the innermost tracking device. Measurements characterising the prototype ATLAS pixel readout chip FE-A/C are described and compared with the requirements of ATLAS. The performance of the chip with radiation tolerant silicon sensors was studied in a test beam at CERN. Furthermore assemblies with diamond sensors have been studied in the laboratory and the test beam. Diamond is a promising sensor material for hadron colliders due to its radiation hardness. The influence of the limited charge carrier lifetime on the detector performance has been examined.

    Full Text Available Articel in German, Abstracts in English and German.For the greater part of his life, Alexander von Humboldt was interested in colour phenomena which he observed in nature. These observations led him to do research into phenomena such as the blue colour of the sky, enigmatic dust and hail, and the colour of plants. Humboldt corresponded with many scientists about the connection between sunlight and the creation of colours, about coloured shadows, the Blue Cave in Capri, the colour of stars, plants etc. Claude-Louis Berthollet developed a model for the composition of a blue colour (Indigo, a technology which was of great importance to the textile industry.The present paper focuses on Humboldt’s interest in the blue colour of the sky, which he shared with artists, writers and scientists like Johann Wolfgang von Goethe, Christian Gottfried Lichtenberg, Caspar David Friedrich and Horace Bénédict de Saussure. During his travels in South America, Humboldt used Saussure’s cyanometer to determine the intensity of the blue colour of the sky. Later he corresponded about this instrument with his friend François Arago who had invented a cyanometer based on chromatic polarisation. While Humboldt was working on his “Cosmos”, Arago explained to his friend the latest results in physics, especially in polarography. Towards the end of his life, Humboldt corresponded with the painter J. G. Schall and admitted that he had somewhat lost his interest in the physical explanation of the blue colour of the sky.

In den letzten Jahrzehnten hat sich die Medienpädagogik zu einer eigenständigen akademischen (Teil-Disziplin entwickelt, die in der (Fach-Öffentlichkeit wahrgenommen wird und sich aktiv in aktuelle gesellschaftliche Diskurse einbringt. Sichtbar wird die Etablierung als Fach u. a. daran, dass an einer Reihe von Hochschulen Professuren geschaffen wurden, die für medienpädagogische Studienelemente oder -gänge und/oder Zusatzausbildungen verantwortlich sind. Der gestiegene Stellenwert der Disziplin zeigt sich auch an ihrer Rolle in der Deutschen Gesellschaft für Erziehungswissenschaft, innerhalb derer sie sich von einer «Arbeitsgemeinschaft auf Zeit» (Mitte der 1990er-Jahre zu einer eigenständigen Sektion (seit 2010 entwickelt hat. Angesichts der gegenwärtig zu beobachtenden Entwicklungen im Medienbereich (u. a. Digitalisierung, Globalisierung, Algorithmisierung, deren Folgen für gesellschaftliche und pädagogische Prozesse und Bereiche kaum zu unterschätzen sind, erstaunt es, dass die Medienpädagogik bis heute dazu neigt, Rechtfertigungsstrategien für die eigenen Existenz zu generieren. Bei einer kritischen Betrachtung (z. B. der universitären Stellenpolitik ist aber zu konstatieren, dass sich die Medienpädagogik auch 40 Jahre nach dem Erscheinen von Dieter Baackes wegweisender Schrift Kommunikation und Kompetenz ihrer Anerkennung und festen Verankerung im akademischen Feld tatsächlich noch immer nicht sicher sein kann. Eine Ursache hierfür liegt möglicherweise in der noch immer grossen (und oftmals geradezu zelebrierten Heterogenität des Faches. So sind die unterschiedlichen Traditionslinien des pädagogischen Umgangs mit Medien, die mitunter nur bedingt miteinander vereinbar sind, bis heute zu beobachten und wirkmächtig. Zu unterscheiden ist hierbei bspw. eine auf Emanzipation, kommunikative Kompetenz und Selbstermächtigung orientierte Linie, die sich in ausserschulischen Settings subjekt- und ressourcenorientiert die Medien als Instrumente subversiver Strategien und/oder der Identitätskonstruktion angeeignet hat. Oft nur bedingt an diese anschlussfähig ist eine schulpädagogische Linie, die ihren Ausgang bei der ‹Film- und Medienerziehung› genommen hat und inzwischen stärker auf Kompetenzerwerb fokussiert. Daneben findet sich dann noch eine (vielfältig ausdifferenzierte ‹Mediendidaktik›, die immer wieder technologie-euphorisch innovatives Lernen versprochen hat. Positiv gewendet, zeigt bereits diese kleine Skizze, dass die Medienpädagogik als erziehungswissenschaftliche Disziplin darauf verweisen kann, wie intensiv Theoriebildung, Forschung und Praxis gegenwärtig in einem breiten Spektrum von Ansätzen, Forschungsschwerpunkten und ‹Schulen› vollzogen wird. Das Fach ist also sehr lebendig – erscheint aber aus der Perspektive externer Beobachter möglicherweise auch als diffus.

    The German Federal Government has formulated a national reduction target, which, by the year 2005, provides for a reduction of CO[sub 2] emissions by 25 to 30% compared with the reference year 1987. A significant contribution to the attainment of this reduction target is expected from the German electricity industry. This paper discusses the potential for CO[sub 2] reduction in the German electricity industry on the basis of an analysis using a model. Complementary to this, the paper reports on the status and execution of such measures within individual German electricity supply undertakings. (orig.)

    The NPP Philipsburg-2 has violated existing safety requirements for 32 years: Due to the bolt breaks in ventilation channels four safety injection systems could fail in case of an incident. The NPP was built deviating from the design with respect to the safety against strong vibrations. A rather earth quake or military aircraft crash could trigger a severe accident. Further safety deficiencies concern insulating materials in the sump, insufficient cooling water levels during start-up and fire prevention.

  18. Investigation of new materials for SOFC applications; Untersuchungen zum Einsatz neuer Werkstoffe fuer SOFC-Anwendungen

    Energy Technology Data Exchange (ETDEWEB)

    Wackerl, J.

    2007-05-04

    Fuel cells based on solid oxides ('SOFC') are excellent alternative devices for power generation, when they are operated at high temperature, e.g. above 600 C. Having only fixed parts for the power generating part of the device is only one advantage of the fuel cell. Due to their unique design, these devices offer a maximum of efficiency for energy conversion compared to conventional power generating systems, which are mainly based on turbines. One aim of this thesis is the examination of alternative electrolyte and cathode materials for the SOFC applications at reduced temperatures, which means in the temperature range between 600 C and 750 C. For the first main task, several materials from the oxygen ion conducting electrolytes were selected. Different strontium and magnesium doped lanthanum gallate (LSGM) materials with additional transition metal doping were selected and prepared via two different preparation methods. The optimum calcining conditions were determined using thermal analysis methods. The results of the structural analysis of the sintered electrolyte materials were used to select the most suitable electrolyte materials. As a result, LSGM and iron doped LSGM (LSGMF) were the most promising materials. Further investigations were carried out on LSGMF materials with different strontium content. The influence of chemical cation non-stoichiometry on the perovskite material was investigated. Therefore, measurements to gather information about the crystallographic structure, morphology, electrochemistry and electrical conductivity were carried out. For a selected sample, the correlations between single effects, such as the crystallographic structure, and the electrical properties are shown by combining the different analysis methods. It could be shown that both the electrochemistry and the crystallographic structure have a significant influence on the electrical conductivity of the LSGMF materials. The second aim of the thesis was the selection and preparation of suitable cathode materials for the SOFC operated at reduced temperatures. The focus for this selection was laid on the chemical compatibility with LSGMF and Scandia doped yttria (ScSZ) based electrolyte materials. Most of the cathode materials could be prepared single phased, with the exception of a strontium doped lanthanumcuprate and a strontium doped lanthanumnickelate. The third aim of the thesis was the investigation of the chemical compatibility between the prepared cathode materials and the electrolyte materials ScSZ and LSGM. The combinations of electrolyte-cathode materials were annealed at commonly used co-sintering temperatures but for extended sintering times. X-Ray diffraction patterns (XRD) and scanning electron microscopy (SEM) were used for the investigation. Based on the examination of the appearing primary and secondary phases and the morphology a ranking of the combinations is given. The least chemical reactions with both electrolyte materials were observed for a strontium doped lanthanum manganite. However, a strontium and copper doped lanthanumferrite seems to be the most promising cathode material for reduced temperatures. (orig.)

    Full Text Available Language is without any doubt a societal phenomenon, which is in many more ways related to space. While francophone, anglophone and Spanish geography have developed a kind of language geography or geolinguistics as a subdiscipline of geography, geographers in German-speaking countries pay some attention to this fact only within ethnic geography. The paper highlights some more important spatial aspects of language and proposes to regard language geography as a subdiscipline of cultural geography which has to co-operate closely with linguistics and history.

It is presumed that the suggestive power of the state run poster propaganda greatly contributed to winning the approval of the majority of Americans, which resonated in the United States’ total mobilization. Three posters of the Committee on Public Information and the U. S. Food Administration are used to demonstrate how the enemy was represented and how the inclusion of children and emigrants helped to evoke a patriotic spirit as well as an idea of national unity in the observer.

    Full Text Available [english] Mobile devices with a connection to the internet – smartphones – are seen all over the place since the popular introduction of the Apple iPhone. Similar products existed but no company managed to combine simplicity and functionality so seamlesly. Their market share increases constantly and web sites get optimised for the small display sizes (often referred to as „responsive webdesign“ otherwise the usability lacks. Students seem to like smartphones aswell and a good question is if and to what extend those devices can play a role in e-learning.„Mediman“, an adaptation of the common game Hangman has been developed for smartphones. Test users asked to complete an online questionnaire. So far, only few e-learning applications for smartphones seem to exist. This is reflected in the low usage frequency. Especially the fact that most of the test users wear a smartphone with them all the time makes it an ideal learning plattform. Short learning sessions were rated more important than continuous text. The majority of the 11 test users rated Mediman as well developed. The foremost question whether a smartphone e-learning application is feasible must be answered positive – acceptance in the test user group was shown. E-learning applications on smartphones will be an important topic in the future as market shares increase constantly. Further studies are required due to the small number of partitipants in our survey.

Zur Zeit scheinen nur wenige Lernanwendungen für Smartphones zu existieren, was sich in der eingeschränkten Benutzungshäufigkeit widerspiegelt. Vor allem die Tatsache, dass Smartphone-Besitzer ihre Geräte meist bei sich tragen, wird als ideale Voraussetzung gesehen, die Geräte für Lernanwendungen einzusetzen. Hier scheint vor allem das Lernen in kurzen Sitzungen von Interesse. Mediman wurde von der Mehrzahl der 11 Testbenutzer als gut umgesetzte Beispielanwendung bewertet. Die zentrale Frage der Umsetzbarkeit einer Smartphone-Lernanwendung wurde damit erreicht – die notwendige Akzeptanz scheint vorhanden.Für die Zukunft ist mit einer zunehmenden Verbreitung von Smartphones zu rechnen, sodass Lernanwendungen und –szenarien für Endgeräte mit kleinen Bildschirmen optimiert werden sollten. Aufgrund der geringen Fallzahl in der Onlineumfrage sollten weitere Untersuchungen angeschlossen werden.

    In this paper, we present an autonomous sensor network for monitoring and power load optimization of high-voltage power lines. We also discuss results from tests in high-voltage laboratory and on 110 kV power lines. The system consists of several sensor nodes, which are directly mounted to the power line conductor. Additional components on the pylons are not needed. The energy required for the operation of the sensor nodes is harvested from the electric fringing field of the power lines. The sensor data consisting of temperature, magnitude of the current, and conductor sag is passed along the chain in the 2.4 GHz ISM frequency band and collected by a base station. In the base station, which is located at the substation, the incoming data are processed in the form of a web server with a database system and provided to the control station of the electric power transmission system operators.

    Full Text Available [english] Introduction: Traditional university teaching formats are of limited use when it comes to conveying the inner workings and specific remit of general medicine in a practical way. Small supervised groups present themselves as a plausible and effective alternative for learning to interact with patients in low prevalence areas.Description of the project: A frontal lecture was transformed into an interactive seminar-like lecture for 280 students. Short kick-off presentations served as an introduction to rotating circuit stations. Knowledge, skills and professional attitude specific to general and family medicine were intensively trained by 28 small groups in and around the auditorium by means of activating didactic methods. The small groups were supervised by experienced GP’s trained as tutors. During six days, consisting of 3.5 hour sessions per day, working methods, a large variety of common medical conditions, preventive primary care and care for the elderly were amongst the topics addressed. Results: This new format was successfully implemented and developed with regards to content as well as organisation. Well over 90% of the 274 participating students evaluated tutors’ commitment, coherent delivery of content, learner-oriented atmosphere and practical focus positively. Given the advantages of a small-group learning situation, the somewhat cramped conditions were accepted by 92%.Discussion: The innovative concept was able to work successfully within the specific framework of patient care in a general and family medicine setting. A creative approach to the lack of space managed to mobilise resources for practical small-group work. Being able to work on specific general practice problems in a small-group setting and immediately reflect upon them was rated positively overall.Conclusions: Responsibilities and specific working methods in general practice / family medicine can be trained successfully even with large groups of students when limited space is used creatively. In a supervised circuit-training setting, students are able to apply their existing knowledge and skills in a practical way. Further research is needed to assess individual learning success and gains in competence under this novel learning situation.

    Energy Technology Data Exchange (ETDEWEB)

    Fabis, R.M.

    2006-07-01

    Modern vehicles have faced a continuous rise in power demand over the last decade. It is neither possible to cover all energy needs reliably, nor to guarantee a successful cranking. Therefore new solutions are needed, such as energy management or the introduction of 42V-technology (mild hybrid). This dissertation discusses the design requirements of energy management systems (e.g. power-train dimensioning) and considers some interventions (e.g. reduction of power demand, motor idle speed lifting), as well as the associated consequences (battery state, consumer satisfaction). The dissertation contains an example of the energy management system, which is based on the battery- and alternator specific data. Different aspects are emphasised regarding the 42V-technology: impact of the energy management on the battery state, optimisation of the battery state of charge, support of the combustion engine by the electrical system when cranking and/or bringing up to speed, and recovery of the braking energy. The dissertation shows the methods for the validation of energy management systems, which are based on Matlab/Simulink simulations. Several battery-, alternator- and consumer models are shown. Finally a tool chain is presented, which allows the automation of simulation processes. (orig.)

  5. Kurz zum Klima: Kommt Fisch in Zukunft noch auf den Tisch?

    OpenAIRE

    Luise Röpke; Jana Lippelt

    2010-01-01

    Um den derzeitigen Pro-Kopf-Verbrauch an Fischprodukten beizubehalten, müsste die jährliche Fischproduktion bis 2030 um 40 Mill. Tonnen anwachsen. Eine solche Ausweitung lässt sich mit konventionellem Fischfang kaum erreichen. Denn neben der Überfischung stellt der Klimawandel eine potentielle Bedrohung für die Fischbestände und damit für die Fischerei dar. Eine Möglichkeit, die weltweit steigende Nachfrage nach Fischgütern zu bedienen, bietet die Aquakultur.

    During operation of nuclear power plants, the quality of systems, structures and components may change as a result of ageing (conceptional ageing, technological ageing or physical ageing), which will affect the system quality. Ageing management is necessary to ensure safety and availability throughout the life of the systems. This necessitates a systematic, integrative and knowledge-based approach. Systems, structures and components are grouped according to their relevance for meeting the set goals. Ageing mangement should be process-oriented and should be integrated in the organisational procedure in cooperation with the safety manager. The procedure should follow the PDCA principle (plan - do - check - act). The data, documents, knowledge and evaluations required for ageing management are part of the knowledge base of the nuclear power station and are updated regularly. The efficiency of ageing management must be reassessed at regular intervals. (orig.)

    Looking at the year 2005 and the end of disposal of untreated domestic waste the politic hopes that the prognosticated lack of waste treatment capacity is remedied by coal-fired power plants. The classical municipal waste incinerators by contrast want to get recognition as energetic recycler in comparison with power stations. The decision of the European Court of Justice concerning recycling and disposal of domestic waste by incineration has started the discussion and competition on fuel-rich commercial waste. Are municipal waste incineration plants power stations or must power plants be regarded as incinerators? These questions are still open. (orig.) [German] Mit Blick auf das Jahr 2005 und das Ende der Ablagerung von unbehandeltem Siedlungsabfall hofft die Politik, dass der prognostizierte Mangel an Vorbehandlungskapazitaeten von den Kohlekraftwerken behoben wird. Die klassischen Muellverbrennungsanlagen wollen dagegen mit dem Kraftwerksvergleich die Anerkennung als energetische Verwerter erreichen. Das EuGH-Urteil zur Verwertung oder Beseitigung von Siedlungsabfall durch Verbrennen hat in diesem Jahr die Diskussion und den Kampf um den heizwertreichen Gewerbeabfall angeheizt. Die Frage, wie weit in Zukunft die Muellverbrennungsanlagen als Kraftwerke, aber auch die Kraftwerke als Muellverbrennungsanlagen angesehen werden muessen, ist noch offen. (orig.)

    In the torrefaction process biomass is heated up in the absence of oxygen to a temperature of at least 250 C. By combining torrefaction with pelletisation or briquetting, biomass materials can be converted into a high-energy-density bioenergy carrier with improved behaviour in (long-distance) transport, handling and storage. Torrefaction also creates superior properties for biomass in many major end-use applications. The process has the potential to provide a significant contribution to an enlarged raw material portfolio for sustainable biomass fuel production inside Europe by including both agricultural and forestry biomass (residues). The article will briefly introduce the concept and objectives of the project and the different torrefaction technologies involved and then focus on the results obtained within the first project phase of the EU-project SECTOR. This comprises production of torrefied biomass batches, subsequent densification (pelletisation and briquetting), characterisation and Round Robin testing of characterisation methods, initial logistics and end-use performance testing, material safety data sheet preparation and sustainability assessment along the value chain.

  18. Verantwortung für die Fraglichkeit des Menschen? Zum Status der Philosophischen Anthropologie

    Directory of Open Access Journals (Sweden)

    Hans-Peter Krüger

    2016-09-01

    Full Text Available Responsibility means not just to give the right response to a question. It should not necessarily succeed to ask and respond about acts, and to submit them to some discursive rules. In fact, responsibility is related to an indefinite questioning: How could some question-answer-rules, which consequences exceed a situation, be adequately applied to this situation? To give an answer to this questionability, it would be necessary to move in a self-relating language as well as in a distancing intuition. Thus, the author argues that it would be irresponsible if the philosophic-anthropological question about the human being could be answered by the application of some discursive rules.

    This article takes a look at two Swiss companies, both founded in 1991, that were initially laughed at but are now two market leaders in their business segments. They demonstrate that renewable forms of energy are an economic factor that is to be taken seriously. The first company discussed is Sputnik Engineering who build and sell inverters for photovoltaic installations. The success of this Swiss company, especially in Germany, is discussed and the importance of reliable inverter technology for the high availability rates needed by solar installations is discussed. The second company looked at is the Kompogas AG, who manufacture and operate digester systems for green wastes from kitchens and gardens. These fermenters produce biogas which can be fed into the gas mains or used as a fuel for vehicles or combined heat and power units. Market chances at home and abroad are discussed.

    Due to their high dry matter yield potential Sorghum bicolor and Sorghum bicolor x sudanense are well fitted as feedstock for biogas production. Similar to maize, both species show a high efficiency in their use of water (C4-plants). However, Sorghum has a higher drought tolerance in comparison with maize but is more sensitive to low temperatures. Hence a cultivation of Sorghum is recommendable especially in dry and relatively warm regions, including recultivated areas and even on loess soil, provided that the required temperatures are given. Due to the fact that Sorghum is not affected by the corn root worm, it also could gain relevance in regions were the cultivation of maize is restricted. Furthermore, Sorghum is usable as a catch crop as well as a main crop because of its variable sowing time. Catch crop cultivation, however, yields a significantly lower amount of dry matter and -quality which is a result of its shorter vegetation period. Owing to its higher crude fiber concentration Sorghum achieves a lower theoretically attainable specific methane yield (Weissbach) than maize. Thus only on rare occasions Sorghum does achieve methane yields per hectare that are comparable to maize. Eventually, the competitiveness of Sorghum greatly depends on provision of enhanced cultivars achieved through genetic improvement. (orig.)

    This publication of the Swiss Federal Office of Energy (SFOE) presents a review of the SFOE's Electricity Research Programme's main areas of activity in 2004. In the electricity transport and storage area, future energy networks, decentralised power generation and storage, energy flow optimisation, compressed air storage systems and corrosion in pipelines caused by alternating current are described. High-temperature superconductors and their potential in power transport and in electrical machines form another topic. In the information and communication technology area, optimised use of electrical energy is looked at, as used, for example, in set-top boxes and smart-home systems. Also, uninterruptible power supplies are looked at. As far as drives and electric motors are concerned, an industry convention is examined as is the optimal purchasing of drives. A functional prototype of an energy-saving motor is described, as are a high-efficiency, gearless drive. Further papers on projects in the compressed-air area are listed. In the devices area, the papers range from energy-efficient hotel mini-bars over water coolers through to optimal energy use in vending machines for cool drinks and refrigeration units in stores. Further topics include dehumidifiers, sewage sludge treatment and a study on the electromagnetic fields of energy-saving lamps. National and international co-operation is reviewed and various pilot and demonstration projects in the above-mentioned areas are briefly presented. The report is completed with a list of research and development projects and a list of pilot and demonstration work.

    Full Text Available This paper analyses the use of metaphor in political speeches addressing the so-called “refugee crisis”. The speeches were made in 2015 in the German parliament by members of the government and opposition. Our findings show that systematic and profound analysis of the apparently trivial assumption that political rhetoric effects public opinion and vice versa, produces significant results in the field of an ethnology of contemporary “Western” national states and their interdependence. This includes their self-understanding as well as the complex dynamics of discourse and power within themselves and on a global scale. The approach presented in our paper is capable of grasping the dynamic socio-cultural negotiation processes currently underway. We argue that it is important to examine the metaphorical dimension of expressions used in political discourses. If these are taken for granted, no scope would be left for alternative expressions and metaphors that trigger different frames and thus enable alternative actions.

    Groundwater can play an important role in lake water and chemical budgets. The aim of this study was to map and quantify groundwater discharge to Lake Steißlingen, a small lake in south-west Germany, using Rn as a natural groundwater tracer. 222Rn, nutrients, temperature and oxygen concentration were measured in depth profiles and in sediment-near water samples during April and June 2016. The spatial distribution of Rn activities (max. 944 Bq m-3) showed that groundwater discharges into the middle of the lake and along the northeastern shore from springs in the hypolimnion (11-14 m depth). Based on a Rn mass-balance groundwater accounts for 70% of the total water input (GWflux = 11 l s-1) to the lake. There were significant positive correlations between methane and nitrite with Rn activity, suggesting the groundwater as a common source. Overall the inflow of groundwater causes a deterioration in lake water quality.

    Full Text Available This study, related to the discussion concerning the basis of an "ÜW" (Science of Translation, aims to show the connection between the problems, which are concretely lived in the praxis of studies and researches (concentrated on the general topic "translation", and the definitions of these problems. The main arguments, which have been expressed in particular since the early 80's, can be described as against or for the "pure" disciplinary structure of a science of translation (ÜW. The study tries to make clear that these arguments have their origin in other disciplines, which aim to incorporate the translation researches. Concerning the theoretical basis of an ÜW (as an opposite/alternative to TS, translation studies the study discusses the possibilities given by the arguments named, particularly those emphasizing the precipice between the "Ü-Theorie" and "Ü-Praxis", the interdisciplinary spectrum of several sciences, the complexity of the subject etc. At the end of the study a proposal is formulated for resolving the main problem (of the discussion itself based on extra-disciplinary approaches. The discussion on the basis of a science of Translation (ÜW must be clarified by a logical order of proceedings and the "dynamic structure" of principle analyses in ÜW, which can be defined as subordination and coordination aspects of the discipline.

    Since the successful reactivation of the schönbuch railway between Böblingen and Dettenhausen the number of passengers has increased continuously. Due to this high demand of over 8000 people per day and the increase of popularity the current expansion projects include the electrification of the 17 km long track and the installation of double-track sections for providing a 15-minute-service between Böblingen and Holzgerlingen. To realize the new operational concept, Zweckverband Schönbuchbahn (ZVS), the public transport authority, has ordered nine light rail-styled vehicles (with costs around 51,3 mio. euro for developing and construction). In this way the schönbuch railway is an important factor to guarantee a sustainable and forward-looking mobility in the metropolitan area of Stuttgart and for restricting car traffic.

    2017-01-01

    Ist Biologie das jüngste Mitglied in der Familie von Big Science? Die vermehrte Zusammenarbeit in der biologischen Forschung wurde in der Folge des Human Genome Project zwar zum Gegenstand hitziger Diskussionen, aber Debatten und Reflexionen blieben meist im Polemischen verhaftet und zeigten eine begrenzte Wertschätzung für die Vielfalt und Erklärungskraft des Konzepts von Big Science. Zur gleichen Zeit haben Wissenschafts- und Technikforscher/innen in ihren Beschreibungen des Wandels der Forschungslandschaft die Verwendung des Begriffs Big Science gemieden. Dieser interdisziplinäre Artikel kombiniert eine begriffliche Analyse des Konzepts von Big Science mit unterschiedlichen Daten und Ideen aus einer Multimethodenuntersuchung mehrerer großer Forschungsprojekte in der Biologie. Ziel ist es, ein empirisch fundiertes, nuanciertes und analytisch nützliches Verständnis von Big Biology zu entwickeln und die normativen Debatten mit ihren einfachen Dichotomien und rhetorischen Positionen hinter sich zu lassen. Zwar kann das Konzept von Big Science als eine Mode in der Wissenschaftspolitik gesehen werden – inzwischen vielleicht sogar als ein altmodisches Konzept –, doch lautet meine innovative Argumentation, dass dessen analytische Verwendung unsere Aufmerksamkeit auf die Ausweitung der Zusammenarbeit in den Biowissenschaften lenkt. Die Analyse von Big Biology zeigt Unterschiede zu Big Physics und anderen Formen von Big Science, namentlich in den Mustern der Forschungsorganisation, der verwendeten Technologien und der gesellschaftlichen Zusammenhänge, in denen sie tätig ist. So können Reflexionen über Big Science, Big Biology und ihre Beziehungen zur Wissensproduktion die jüngsten Behauptungen über grundlegende Veränderungen in der Life Science-Forschung in einen historischen Kontext stellen.

    For the project 'Politics scenarios for climate protection V' (Politics scenarios V), two scenarios for the development of greenhouse gas emissions in Germany for the period 2005 to 2030 were developed: (a) a 'With-Measure-scenario'; (b) a 'structural-change-scenario'. In the context of the scenario analyses a detailed evaluation of the respective climatic political and energy political measures is performed regarding to their effects on the development of the greenhouse gas emissions in Germany. Methane, laughing gas, halogenated hydrocarbons, perfluorinated hydrocarbons and sulphur hexafluoride are considered for the source sectors energy, industrial processes, product application, agriculture and waste management are considered. Sector-specific model analyses are used in the development of the scenarios. These model analyses are summarized to consistent and complete quantity structure for the power requirement and the emissions of greenhouse gases. Specific investigations are accomplished for the areas space heating and warm water, electrical devices, industry, trade and services, traffic, power generation from renewable energies and the fossil power generation as well as for the volatile emissions of the energy sector, process-related emissions of carbon dioxide, methane and nitrous oxides. For other selected sources (emissions of halogenated hydrocarbons and sulphur hexafluoride as well as the agriculture) results of other investigations were taken over and processed. In the case of an integration and determination of emissions a system integration module and an emission computation model are used in order to consolidate the detailed sector results to a quantity structure. This quantity structure completely is compatible to the German greenhouse gas inventories (according to the conditions of the inventory report 2008).

    The research project was started with the objective of developing the essential geological-technical-technological parts of the utilisation of highly-mineralised thermal waters for heating. It is based on the findings from the drilling and testing of 29 deep geothermal wells, the erection and operation of Geothermal Heating Stations in Northeast Germany until 1990. The operation of the Waren (Mueritz) and Neubrandenburg Geothermal Heating Stations including their modernisation and the solution of problems which occurred sometimes give proof of the principal technical-technological implementability of thermal water utilisation for energetic purposes. Matter of concern is the recirculation of the thermal water after being used for balneological purposes to the main flow of water used for energetic purposes without affecting subsequent reinjection. The conditioning of the thermal water before and after use for bathing and balneo-therapeutic purposes is another problrm. The essential results are presented here. (orig.)

    The idea of CO{sub 2} capture and storage (CCS) is to separate CO{sub 2} from energy conversion processes and to store it safely outside the atmosphere e.g. in geologic formations. This concept constitutes a potentially very effective technology for the mitigation of climate change. The worldwide emissions from large power plants - where CCS would be applied primarily - add up to more than 10 billion tons of CO{sub 2} per year. In view of a market volume of several billion Euros per year for large power plants, the economic relevance of these technologies can be considered equally high. Carbon capture and storage is an architectural innovation that is made up from the combination and further development of existing technologies. Within the field of power plants, three main process lines are under development: pre-combustion capture, post combustion capture and oxy fuel. All three process lines are still in an early stage of the innovation cycle, as there are no commercial plants in operation yet. Instead, the first pilot plants are presently under construction and demonstration plants are being planned. The main technical challenges lie in the efficient integration of the separation processes into the power plant process with the aim to minimize the additional energy demand for the capture of CO{sub 2}. There are several groups of central actors in the technology field of CCS. The four large suppliers of electricity generation technologies with an own distinct development of (gas-)turbine technologies, General Electric, Siemens, Mitsubishi and Alstom represent the technology manufacturers. The large utilities such as Vattenfall, RWE, Enel or Endesa make up the potential demand for the CCS technologies and they are partly also involved in their development. The oil and gas majors (e.g. Shell, BP, Statoil) on the one hand are interested in having large volumes of CO{sub 2} for improving the oil production (enhanced oil recovery) and on the other hand, they assess the transport and storage of CO{sub 2} as a potential business area. As a result of the local activities of stakeholders, of public support programmes and of incentives for the industries, active innovation systems have evolved in the United States, in the EU (there especially in Germany) and in Norway. There is a reasonable chance that the technology concept of CCS will make its breakthrough in Europe and possible in Germany, as the European Emissions Trade creates important incentives and as important actors among technology manufacturers and utilities are located in this region. Main challenges lie especially in reaching the objectives for the technological development, in proving the feasibility of save storage and in the public acceptance of the CCS technologies. (orig.)

    The sustainable future market of Solar Cooling Technology is of utmost importance for the sustainability of buildings with air conditioning, especially in countries with intense solar radiation. The application of electrical air conditioning is growing fast and is now spreading to transition economies in East Asia. Solar Cooling is driven by solar heat gathered by solar collectors, usually situated on the roofs of buildings. This heat drives different types of complex, thermodynamic devices which transform heat into cold, using a small amount of electricity to drive pumps. Via a medium the cold is distributed in rooms. Solar Cooling Technology was developed about thirty years ago and the large scale machinery necessary to air condition office buildings is in its maturity phase. However, application experience is widely limited due to a lack of a larger number of applications and especially smaller devices will be necessary to air condition family homes. A number of European start-up companies is active to develop this smaller devices. All over, some 300 buildings use solar cooling in Europe, most of them are research and development applications. The benefit of solar cooling is threefold: - depending on the individual application, solar cooling saves up to 60% of energy compared to electrical air conditioning, - since electricity is saved when sun shines most intensively, solar cooling reduces the burden on the electrical grid at peak times, - the heat used at times, when solar collectors are suffering under high temperature non-use phases reduces the stress on the collectors and may prolong their lifetime. The economic potential of a product market in its infancy is hard to evaluate, but high growth rates of electrical air conditioning in many countries point to the development of a possibly very large market. The world market volume in 2020 was assessed between 4.5 and 18 billion Euro. Countries with highest activity are in Europe. Many start-up companies from the field of solar cooling are German and Austrian firms and many research facilities are distributed in mid and south Europe. The big area of installed solar collectors in Germany and Austria is facilitating applications in these countries. And the regulation demanding mandatory installation of solar collectors in Spain on new buildings is fostering the regional development. Political strategies may target: - the funding of additional pilot projects and small serial applications to support readiness for production of products and application technology, - the information and qualification of those sectors necessary for large scale application, like air condition specialists and architects, - Information and motivation of pilot users. Solar Cooling should also be observed in the design of regulations concerning sustainable building and heating. (orig.)

    Hybrid electric vehicles allow driving quietly and locally emission-free because the internal combustion engine is run in a more favorable load range, while the highly efficient electric motor supports at low speeds and in acceleration phases. Further reductions in fuel consumption are achieved by down sizing the combustion engine and by recuperating brake energy back into the battery. However, the actual environmental and energy advantage strongly depends on driving styles and driving cycles. The technology dynamics of hybrid propulsion systems appears more intensive than the dynamics of its core components: combustion engine, electric motors and energy storage technology. Due to its higher price and the more expensive maintenance the destination countries of the technology are most likely located in North America, Europe, Japan, Australia and the metropolises of South America and Southeast Asia. However, estimates of future market potential widely diverge. With regard to technology, Japan, the United States, France and Sweden are the most important competitors for Germany. European producers, however, are completely dependent on imports and lag sufficient technology competence in key areas, namely in the field of battery technology. Due to specific preconditions and national incentive systems, the competing countries are on different stages of the development processes. Important is the disapproval of diesel for cars in Japan and the USA but also tax incentives and special conditions for hybrid cars, e. g. the Congestion Charge in London. Although Japan appears as the technology leader in the field of hybrid electric vehicles, Germany holds 40 % and the EU 27 60 % of the worldwide patent applications of hybrid propulsion systems and their components. These figures indicate a nameable technological and economic potential of Europe, and especially of Germany, in the field of hybrid propulsion technology, which are the result of the productive and internationally very successful car industry on the one hand and of the high specialization in some key components on the other hand. Also the ambitious environmental policy of the EU as well as of individual member states constitutes a potential advantage. But the different developments in environmental and transport policies are a retarding factor regarding the creation of a standardized large European market for alternative vehicle concepts. Creating reliable incentive systems for clean vehicle technologies across Europe would create a sufficiently large market, allowing European car manufacturers to build up own competences and production capacities for alternative propulsion systems. Challenges in this process are the technology advance of US and Asian manufacturers and the foreseen lack of qualified engineers in Europe. Due to still existing problems with battery capacities or fuel cells, hybrid electric vehicles will play a major role for particular market segments and as a transition technology to totally emission-free propulsion technologies. Moreover, clean diesel technology slowly gains acceptance in the US. Depending on driving patterns and driving habits this concept can even be superior to hybrid electric systems as it does not require heavy batteries and the maintenance of the vehicles is simpler.

    Increased attention is currently being paid to electricity storage as a result of an energy policy which favours renewable energies. As the shares of fluctuating renewable energies (mainly wind and solar power) increase in the total electricity supply, it becomes more and more difficult to balance electricity demand and supply. This is linked to the facts that the share of controllable fossil electricity generation is decreasing (production) and, at the same time, the typically highly regionally concentrated renewable energy production is limited by the capacity of the electricity grid (distribution). Therefore energy research has recently begun focusing on grid-connected electricity storage systems. As electricity itself cannot be stored in large amounts, it is typically converted into other energy forms such as chemical energy, kinetic energy or potential energy. The most important technical data for electricity storage technologies are the specific energy [kWh/kg] and the peak power [kW/kg]. Other important features of electricity storage systems are life time, possible number of working cycles, efficiency and self discharging. Besides the traditional electricity storage systems based on pumped hydropower (limitations due to geological constraints) and lead batteries (limitations due to cost and cycle constraints) there are other storage technologies based on hydrogen, compressed air or REDOX reactions. For these three technologies a more detailed analysis has been done of the political framework conditions, the actors, and innovation indicators. This shows a significant increase in the number of patent applications for these and other storage technologies since the beginning of the 90s. On a global scale, the US and Japan are the leading countries for storage technologies in general, followed by the UK and Germany. Looking only on the European market Germany seems to lead the innovation race in the emerging storage technologies such as hydrogen, compressed air or REDOX. These developments are often driven by small and medium-sized companies. The position of Germany with regard to electricity storage technologies can best be described by a SWOT analysis. The worldwide market developments together with the skilled personnel and the technical capacity in Germany provide a sound basis for German industry. (orig.)

Synthetic biofuels, the so-called BtL (biomass to liquid) processes, are produced using thermochemical biomass conversion. Here, in the first process step, the hydrocarbon structure of the biomass is converted to syngas, a mixture of carbon monoxide (CO) and hydrogen (H2). The second process step uses the purified and conditioned syngas for chemical fuel synthesis. The outcome of the synthesis is gasoline, diesel, or tailor-made fuels for advanced fuel-efficient and low-emission engines. R and D on synthetic biofuel processes is being conducted in several countries around the world, but the global technology leader is without doubt the German company, CHOREN Industries Ltd. in Freiberg, Saxony. Since 1998, CHOREN has been operating a pilot plant for the production of biofuels. At present this plant is being up-scaled and the first commercial production worldwide will start in 2007 with a capacity of 15,000 t/a biofuel. Annually 65,000 t of wood will be processed, including scrap wood. This will produce a high-quality diesel product, marketed under the brand name ''SunDiesel''. This product requires neither any modification to the diesel engine nor to the refueling technique. Because the whole plant is processed, 4,000 l diesel equivalent can be obtained from one hectare of crop. This yield is almost three times that of biodiesel produced from rape. Compared with diesel produced from crude oil, synthetic biofuels reduce the CO{sub 2} emissions by more than 80 %. Nevertheless, the establishment of a synthetic biofuels industry cannot be justified based on climate protection arguments, because the CO{sub 2} balance of direct biomass combustion is more favourable. But assessing the environmental performance and sustainability of a process is a multidimensional approach which cannot be based on the CO{sub 2} balance alone. The European Environment Agency (EEA) assessed the additional biomass potential in the EU 25 which could be made available with environmentally-compatible cultivation. According to this study, until 2020 it would be possible to produce 121 million tons of synthetic biofuels annually with the biomass potential available for energy use. Assuming that the fuel consumption of automotive engines will be lowered by 20 % until 2020, then over 60 % of the diesel and gasoline consumption of the EU 25 could be met by synthetic biofuels. This assessment assumes that the total additional biomass potential will be used for the production of synthetic biofuels which is, of course, not a realistic vision. CHOREN Industries, the leader in the commercialization of the technology, assumes that the first large industrial plant with a biofuel capacity of 200,000 t/a could start commercial operation in 2012, and that 45 to 60 of such plants could be constructed in Europe until 2020. This synthetic biofuel capacity could cover 5 - 6 % of the diesel and gasoline consumption expected at that time at production costs below 0.70 Euro/l. Europe's efforts to reduce its dependency on imported energy coincide with the necessity to develop future prospects for agriculture. The extensive farming subsidies for food production are subject to heavy criticism. In the medium-term, transferring financial resources from agriculture to research, development and education will be indispensable for Europe's future. This will be easier to do if agriculture is able to earn the necessary income itself. Environmentally-compatible farming of energy crops and the provision of organic production residues could become a second powerful income source for agriculture. At the same time, the worldwide export of the BtL technology is an effective contribution to combating global greenhouse gas emissions. (orig.)

    The deregulation of the energy markets has given rise to sustained motion in the prevailing structures and market conditions of the supply industry. Dramatic declines in profits in the electricity sector have, in many companies, prompted reflex-like cost reduction programs which, however, frequently prejudice long-term growth prospects and viable future structures in favour of the results of the next fiscal year. The danger of sacrificing all flexibility and therefore market perspectives by corporate anorexia nervosa is immense.

    On 9th February 1993, the Lower Saxony Government declared that the four nuclear power stations operated in Lower Saxony and currently contirbuting to power supply in Lower Saxony at a rate of 60%, can be dispensed with by the year 2005 without causing reductions in supply safety or standard of living. This statement is based on the finale report of the expert's opinion (12th November 1992) which was produced jointly by Prognos AG, Basle, Pestel Institut, Hannover, and the Oeko- Institut, Freiburg. This experts'opinion has been worked out soundly and correctly, material statements do largely apply but need to be corrected relative to some issues. Hence, the bone of contention is not the experts' opinion proper, but the results and consequences derived there from. The author addresses these in his critical analysis. (orig./UA)

    Germany is a high-wage country. Hence the internationally competitive extraction of raw materials in Germany can only be ensured by highly efficient working processes. Tackling the associated extreme requirements on road-driving, coal winning and transport equipment has resulted in the German mining industry and its suppliers achieving the role of an international leader in technology. To safeguard this position also in the future the successful mechanisation will now be followed by the mechatronisation in the mining industry. Efficiency will be increased by (partial) automation and assistance systems. This contribution is a first step towards a series of articles, which explain the principles of mechatronic development methods in the mining industry and will make the development engineers in the mines aware of the high potential of mechatronics in the mining industry.

    To determine the formation mechanism of acid in fog events, field experiments were carried out at several places in Baden-Wuerttemberg and the Vosges mountains/Alsace. It was the objective of these experiments to quantify all constituents (precursory and end products) involved in the acid formation process. Before, during and after the fog event the gas phase, liquid phase and solid aerosol particles were analyzed chemically and physically as a function of their size distribution. The measurement campaigns were found to have the following common results: 1. The free acid contents of the fog water in the so-called clean-air regions always exceeded those of densely populated areas (except for Strasbourg). However, the absolute loads were higher in the densely populated areas. 2. During the fog events, acid concentration of the liquid phase increased. The same behaviour was exhibited by the equivalent concentrations of NH{sub 4}{sup +}, SO{sub 4}{sup -} and NO{sub 3}{sup -}. 3. The fog water constituents were attributed above all to the leaching of particles and gases. 4. In any case, SO{sub 2} was involved in acid formation in the droplets, since fog water S(IV) had been detected. 5. Carbon-containing particles were enriched in the interstitial aerosol. 6. In the particle phase, the maximum of free acid was found only after the fog event. 7. About 30% of SO{sub 4}{sup 2-} was incorporated into the fog droplets. 8. The N(V) loads of the fog water nearly corresponded to the total of gaseous HNO{sub 3} and particle nitrate prior the fog event. For a period of several hours following the fog event, no gaseous HNO{sub 3} and no particle nitrate were found. (orig.) [Deutsch] Zur Klaerung des Bildungsmechanismus der Saeure in Nebelereignissen wurden Feldexperimente zur Quantifizierung aller am Saeurebildungsprozess beteiligten Inhaltsstoffe (Vorlaeufer- und Endprodukte) an mehreren Standorten in Baden-Wuerttemberg und in den Vogesen/Elsass durchgefuehrt. Es wurden die Gasphase, die Fluessigwasserphase und die festen Aerosolpartikeln vor, waehrend und nach dem Nebelereignis in Abhaengigkeit von der Groessenverteilung chemisch und physikalisch untersucht. Folgende, allen Messkampagnen gemeinsame Ergebnisse, wurden gefunden: 1. Die freien Saeuregehalte in den Nebelwaessern waren in sogenannten Reinluftgebieten (mit Ausnahme von Strassburg) immer hoeher als in Ballungsgebieten. Die absoluten Frachten sind aber in den Ballungsgebieten hoeher. 2. Waehrend der Nebelereignisse stieg der Saeuregehalt in der Fluessigphase an. Ein gleiches Verhalten zeigten die Aequivalentkonzentrationen von NH{sub 4}{sup +}, SO{sub 7}{sup 2-} und NO{sub 3}{sup -}. 3. Die Nebelwasserinhaltsstoffe waren im wesentlichen durch die Auswaschung von Partikeln und Gasen erklaerbar. 4. An der Saeurebildung in den Troepfchen war auf jeden Fall SO{sub 2} beteiligt, da im Nebelwasser S(IV) gefunden wurde. 5. Kohlenstoffhaltige Partikeln haben sich im interstitiellen Aerosol angereichert. 6. In der Partikelphase trat das Maximum an freier Saeure erst nach dem Nebelereignis ein. 7. SO{sub 4}{sup 2-} wurde zu ca. 30% in die Nebeltroepfchen inkorporiert. 8. Die N(V)-Frachten im Nebelwasser waren nahezu gleich gross wie die Summen von gasfoermiger HNO{sub 3} und Partikelnitrat vor dem Nebelereignis. Nach dem Nebelereignis wurde fuer mehrere Stunden keine gasfoermige HNO{sub 3} und auch kein Partikelnitrat gefunden. (orig.)

    Full Text Available Im Sinne einer pragmatistischen Perspektive, wie sie zuerst John DEWEY (1987 [1934] in Anschluss an William JAMES formulierte, ist das Religiöse weniger als eine spezifische Art von experience zu verstehen, denn als ein adjustment hin zu einer epistemischen Perspektive, die alle Erfahrungen in einem veränderten Licht erscheinen lässt. Religiosität zielt damit auf ein besonderes Selbst- und Weltverhältnis, in dem die Beziehung zwischen Selbst und Welt aus einer ganzheitlichen Perspektive betrachtet wird. Wie aber können fremde, auf den ersten Blick in ihrer Genese unwahrscheinliche und unter modernen Verhältnissen zudem anzweifelbare religiöse Haltungen und Sinnsysteme etabliert werden? Am Beispiel der im tibetischen Buddhismus verbreiteten Phowa-Meditation des "bewussten Sterbens" wird untersucht, wie für westliche Adept/innen auf den ersten Blick befremdlich und esoterisch anmutende spirituelle Lehren mit zunehmender Praxis an Evidenz und Sinnhaftigkeit gewinnen können, indem sich Gruppenprozesse, Visualisierungen, körperorientierte Übungen und psychisches Erleben zu einem übergreifenden Arrangement verschränken. Die empirische Datengrundlage für die Untersuchung liefern narrative Interviews mit westlich sozialisierten Schüler/innen und Lehrer/innen des Diamantweg-Buddhismus, der derzeit größten buddhistischen Gemeinschaft des tibetischen Buddhismus in Deutschland.

    The cytoprotective agent amifostine (AMI) is capable to protect healthy cells (contrary to tumor cells) due to higher activity of alkaline phosphatase at the membrane site of normal cells. In seven clinical trials the influence of AMI on the pharmacokinetics of different cytostatics was investigated. Preadministration of AMI increased Cmax of doxorubicin (+ 44 %, p < 0.06), epirubicin (+ 31 %, P < 0.08), mitomycin C (+ 41 %, p < 0.01) and docetaxel (+ 31 % and + 17 %, not significant). In contrary, the peak concentration of pirarubicin , the tetrahydropyranyl-prodrug of doxorubicin was decreased (- 50 %, P < 0.03), leading to an equal higher concentrationof doxorubicin in the blood . In accordance to the peak concentrations, the AUC'ast was increased by chemoprotection: doxorubicin + 53 % (p < 0.01) and epirubicin + 23 % (not significant), docetaxel + 25 % and + 31 % (not significant). AUC'ast of mitomycin C and paclitaxel seemed to be unaffected by preadministered AMI. A particular inhibition of the protein binding by AMI has been identified as one reason for higher serum concentrations of anthracycline drugs. After cytoprotection, a possible increase of the cytostatic's Serum concentrations should be taken into account for optimal dosage schedules.

    Starting from the assumption that knowledge is closely linked with people and that it continues to develop among these people, three major areas can be identified as ''sources of knowledge'' on which approaches to knowledge management can be based. 1. If people make their knowledge available in the form of information in documents, then the need arises for information from this source of ''knowledge'' to be retrievable and extractable easily and systematically once a certain magnitude has been reached (document orientation). Typical approaches to this are e.g. literature databases and search tools including conclusive searches across documents. 2. Since the documents were written by people, it might be thought that people themselves can be regarded as a source of ''knowledge'', coupled with the wish to be able to find and contact these people easily and systematically. Although such a search would not yield any content like documents do, it would reveal people who could disclose such content and probably even more comprehensively than documents. Approaches to this are oriented towards people or the individual knowledge carriers. Typical approaches are Yellow Pages and expert-finding systems. 3.As an alternative to the many one-to-one links of the above approach it is possible to encourage a topic-centered organizational structure within which information is obtained and passed on. The source of ''knowledge'' is the social interaction in organizational structures / the networks, coupled with the wish to promote knowledge sharing across departmental boundaries and to keep knowledge that has been gained alive in the company. Typical approaches are e.g. communities of practice or promotion of learning processes (e.g. lessons learned, best practices, interrupted case study) Knowledge sharing plays an important part in the two last-mentioned points and will therefore considered in greater depth. Is knowledge sharing a natural behavior or rather a social dilemma? What do the behavioral sciences say about knowledge sharing on the web, which could substantially benefit companies, following the principle: It is not necessary for everybody to know everything, but all knowledge is immediately available wherever it may be needed.

    When correctly used, wood is an eco-friendly fuel. By using well-processed wood from local sources in a properly handled modern fireplace, you can enjoy the cosy warmth from your wood-burning stove or boiler without causing significant environmental damage. The environment and your neighbours will be grateful for this. This brochure is intended to give you tips on how to properly operate a wood-based heating system - in technical terms referred to as a small combustion installation. Especially the burning of poor quality wood in old and insufficiently maintained stoves and unfavourable combustion conditions will result in the emission of unnecessarily high levels of greenhouse gases having adverse effects on the climate, and pollutants detrimental to your health. Particularly in urban agglomerations and valleys, the air quality is affected by wood heating systems due to low chimneys. Often, neighbours will feel annoyed.

    On behalf of the Ministry of Environment the Austrian Academy of Science published guideline values for nitrogen dioxide in 1988. The scientific database concentrated on short-term effects of NO{sub 2} at that time. After checking the current literature it was clear that new data especially for long-term effects of NO{sub 2} were available which should lead to a limitation of an annual average. Two Austrian studies on children from Linz (capital of Upper Austria) showed that high long-term concentrations of NO{sub 2} were negatively associated with the flow parameters of terminal airways in spirometry (MEF{sub 25} and MEF{sub 50}) on a significant level. In addition the children showed an improvement in growth-dependent increase of lung function parameters when long-term NO{sub 2}-concentrations in the ambient air could be decreased by more than 40 {mu}g/m{sup 3}. The most pronounced benefit could be seen when the ambient level of NO{sub 2} decreased during periods of accelerated growth. Based on these and other results summarized in this review, the Austrian Academy of Science recommended an annual average of 30 {mu}g/m{sup 3} for NO{sub 2} in the ambient air not to be exceeded for health protection. (orig.) [German] In Oesterreich werden von der Oesterreichischen Akademie der Wissenschaften (OeAW) im Auftrag des Bundesministeriums fuer Umwelt, Jugend und Familie fuer die konventionellen Luftschadstoffe wirkungsbezogene Immissionsgrenzkonzentrationen erarbeitet, die den jeweiligen Stand der (medizinischen) Wissenschaft repraesentieren. Ausgehend vom Basiswerk aus 1988 wurde 1998 eine neue Literaturstudie erstellt, die auch Publikationen der letzten Jahre umfasste. Anhand dieses neuen Datenmaterials zeigte sich, dass die Einfuehrung einer Langzeitimmissionsgrenzkonzentration aus umwelthygienischer Sicht notwendig war. In zwei Studien an Linzer Kindern konnte festgestellt werden, dass einerseits hohe NO{sub 2}-Konzentrationen signifikant negativ mit den Lungenflowparametern der kleinen Atemwege (MEF{sub 25} und MEF{sub 50}) korrelierten, andererseits Verbesserungen der Luftqualitaet (Reduktion der NO{sub 2}-Konzentration um mehr als 40 {mu}g/m{sup 3}) auch einen positiven Einfluss auf die wachstumsbedingte Entwicklung der Lungenfunktion der beobachteten Kinder zeigten. Trat die Verbesserung der Luftqualitaet waehrend einer Phase starken (Lungen-)Wachstums auf, war der Benefit besonders gross. Gestuetzt auf diese und andere im folgenden Uebersichtsbeitrag zusammengefasste epidemiologische Ergebnisse wurde von der oesterreichischen Akademie der Wissenschaften ein Langzeitmittelwert von 30 {mu}g/m{sup 3} fuer NO{sub 2} als wirkungsbezogene Immissionsgrenzkonzentration vorgeschlagen.

    Full Text Available The author of this article presents migration as a social phenomenon, which constitutes a challenge for both the international community and particular countries. The involvement of the Holy Father John Paul II, as well as the variety of problems featuring in messages for the World Day of Migrants allow the reader to perceive the issues connected with migration as extremely urgent - both for individuals and for communities, among which the family is of greatest importance. The reason why the Holy Father committed himself to this fi eld was to uphold human dignity and a global social solidarity. The analysis of this phenomenon allows the Holy Father to address a call for responsibility to various groups whose integral activity can make the phenomenon of migration more digni fi ed. The messages of the Holy Father also offer a direct invitation to all people of goodwill to make their own contribution so that every person and family are respected and discriminations that undertime human dignity.

    Within this thesis, instruments for the localised characterisation of fuel cells and fuel cell stacks have been created. The simultaneous multi-channel impedance spectroscopy was implemented and applied to fuel cells for the first time. A measurement device has been developed that can be used to simultaneously apply various localised measurement methods to fuel cells during operation. Within this work, mainly current density and localized impedance measurements were used. Additionally, the temperature distribution of the active fuel cell area was determined and the water condensation was visualised. Several fuel cells have been developed, constructed and assembled to carry out localised characterisation. An algorithm has been developed to evaluate impedance spectra that separate the processes in the fuel cell according to their different time constants. This algorithm is based on a system of physical model equations that provide time- and location-dependent descriptions of the different processes in the cell. This allows the quantitive extraction of physical parameters from the impedance spectroscopy results. To perform localised simulation, a three-dimensional, two-phase, stationary model was adopted cell. A simple one-dimensional fuel cell geometry was used to demonstrate that the three-dimensional model reliably describes the processes under various operation conditions. The model validation was also successfully carried out for various complex fuel cell geometries. With the localised characterisation methods, air flow field geometries of fuel cells were successfully analysed. It could be explained how the microporous coating of the diffusion layer influences the current density distribution. The water balance of a number of different gas flow geometries was successfully characterised. As a result, an optimised flow field design with a double meander has been developed. The water content has been improved so that the efficiency is increased, and the current density distribution is more homogeneous. Multiple meanders are known from other technical applications. The localised characterisation carried out in this thesis demonstrated for the first time the superiority of this geometry. Here, the ratio of channel rib width is important, and the double meander design provides an optimal gas supply due to higher convective transport in the diffusion layer. This geometry was superior to all other evaluated air flow fields with regard to the power density and the homogeneity of the current production in the active area. It could be shown that geometries with parallel channels have considerable disadvantages. Individual channels may be clogged by liquid water. Since no considerable pressure builds up in the clogged channel, the water is not reliably removed. This problem is exacerbated with the interdigitated structure where the dead-end channels are even more easily clogged. Therefore, such flow field designs cannot provide a high fuel cell power density. Furthermore, the simultaneous impedance spectroscopy was used to determine a flooding event of a fuel cell in a stack a few minutes before the flooding event resulted in a reduced power production in this cell. The model-based evaluation of the measured impedance spectra was used to clearly identify the flooding event and quantify the reduction of the open space in the porous electrode of the fuel cell. Due to these findings, a new control concept for fuel cells could be developed that is based on the impedance measurement. It was shown that the impedance spectroscopy can be used to identify malfunctions in advance caused by liquid water. The air flow variation is a suitable instrument to actively intervene in the fuel cell operation and to prevent flooding events. Controlling the fuel cell operation using a combination of the impedance spectroscopy and the air flow variation is an ideal instrument to stabilise the fuel cell operation at a high level. (orig.)

    The WEC study has clearly shown that despite all conceivable efforts in the field of environmental protection an increase in world energy consumption must also be anticipated in the future. The main cause of this increase is the growing energy requirement in the developing countries, which not only anticipate a high growth in population, but also rising per capita income in view of increasing prosperity in the next 30 years. Both will be reflected in an increasing energy requirement in these countries. According to the WEC study oil will still be the most important energy source ahead of coal in the year 2020, although the latter has substantially larger reserves. The background to this situation is the sharp fall in coal production and consumption in the CIS and in Central and Eastern Europe in the course of the transition from planned to market economies. 11 refs., 3 tabs.

    Die Newtonschen Prinzipien und die aus ihnen gewonnene Erkenntnis der Existenz von Elementarkonstanten nach Planck, Einstein und Bohr erweisen sich zunehmend als tragfähiges Fundament nicht nur der Physik und ihrer Anwendung in der Technik, sondern überhaupt aller exakten Wissenschaften in breitestem Sinne des Wortes.Die physikalisch inhaltliche Klärung der Begriffe erfolgt seit Newton in engem Verbund mit der Entwicklung mathematischer Methoden. Diese Kombination erweist sich weiterhin als produktiv und sichert den Fortschritt der Physik und der exakten Wissenschaften.Wohl alle Probleme, die im Bereich der Technik Bedeutung haben können, lassen sich bei entsprechendem Aufwand bereits mit dem vorhandenen Fundus an Erkenntnissen und Methoden erfolgreich angehen.Der in der Wirklichkeit verankerte Zusammenhang von Gesetz und Zufall erweist sich als eine Manifestation der Dialektik in der Natur. Es gibt keinen absoluten Zufall. Sie kommt in allen Zweigen der Physik, nicht nur in der Thermodynamik und Quantenphysik, zutage, und muß bereits auf dem Niveau der Newtonschen Prinzipien und der Elementarkonstanten behandelt werden.Die theoretische Physik, so wie sie von Newton initiiert worden ist, wurde so angelegt, daß sie alle Seiten der Wirklichkeit, so weit sie in die Kompetenz der Physik fallen, umfaßt. Es besteht darum kein Gegensatz zwischen der klassischen Physik und der Quantenphysik. Es handelt sich lediglich um eine Differenzierung nach den unterschiedlichen physikalischen Inhalten und den angemessenen mathematischen Methoden, die natürlich von der Wahl der Probleme abhängen.Die theoretische Physik stellt eine allgemein zugängliche Zusammenfassung des gesicherten Wissens der Physik dar, das zugleich das Fundament der exakten Wissenschaften ist.Die theoretische Physik ist damit das Mittel der Verständigung innerhalb der Kooperation, die notwendig ist zur Lösung der großen komplexen Aufgaben der Wissenschaft und Technik.Translated AbstractThe Meaning and Abilities of Theoretical PhysicsThe Newtonean principles and - derived from them - the congnition of the exixtence of elementary constants according to Planck, Einstein and Bohr increasingly prove to be a strong base not only of physics and its apllication in technology but also of each kind of exact sciences in the broadest sense of the word.Since Newton the clarification of concepts with regard so their physical takes place in close connection with the development of mathematical methods. This combination proves to be further productive and ensures the progress of physics an of the exact sciences.Most likely all problems which may be of importance in the realm of life can be treated successfully - adequate expenditure taken for granted - with the existing fund of knowledge and methods.The connection between law and accident resting on reality proves to be a relation of complementarity (there is no absolute accident). This becomes evident in all branches in all branches of physics, not only in thermodynamics and quantum physics, and can be treated already on the level of the Newtonean principles and elementary constants.Theoretical physics as initiated by newton was designed to comprise all parts of nature. About that there is no contrast between classical physics and quantum physics. It is only a matter of differentiation with regard to the different physical contents and the appropriate mathematical methods, dependent of course on the choice problems.Theoretical physics represents a generally available concentration of the reliable knowledge of physics, which is at the same time the foundation of the exact sciences.In this way theoretical physics is the means of communication within the cooperation necessary for the solution of the great complex tasks of science and technology.

    By means of classical physics the tunnel effect is not explainable. Therefore the nature uses a trick from quantum mechanics: Particles, which possess no sufficient energy to overstep a barrier, ''tunnel'' simply through it. On this principle base both the nuclear decay and the heat-giving nuclear fusion in the sun and many further phenomenas of physics. Experimental studies recently showed that the particles tunnel thereby faster than light spreads in the vacuum. The ''mount to be tunneled through'' behaves thereby as a space without time. Is by this Einstein's theory of relativity disproved? Or even the causality principle violated? Answers give the authors in this draft on superluminal phenomena.

    Prognosis and clinical management of patients with gastrointestinal stromal tumors (GIST) has changed significantly with the introduction of new molecular-targeted drugs such as imatinib. This development is accompanied by a need to re-evaluate the established imaging criteria used to assess treatment response. The frequently used response evaluation criteria in solid tumors (RECIST) are mainly based on one-dimensional tumor size and do not take into account functional changes in responding GISTs such as a decrease in CT density or in the number of intratumoral vessels. Positron emission tomography (PET) has been found to be highly sensitive in detecting early response and to have a predictive value in the long term response to imatinib treatment. Monitoring the course of the disease by PET is limited due to scanner availability and economic constraints. Modified CT response criteria using a combination of tumor density and tumor size are especially promising in early response assessment and have a good prognostic value. Further optimization of existing response criteria and evaluation of new candidate markers of treatment response, such as quantitative perfusion will be the key for optimized monitoring of targeted therapies in GIST. (orig.) [German] Prognose und klinisches Management von Patienten mit gastrointestinalem Stromatumor (GIST) haben sich nach Einfuehrung neuer molekularer Pharmakotherapien wie Imatinib dramatisch geaendert. Damit einhergegangen ist die Notwendigkeit, bisher etablierte bildgebende Methoden zur Beurteilung des Ansprechens auf die Therapie zu ueberdenken. Die derzeit am haeufigsten eingesetzten Responsekriterien, die RECIST- (Response-evaluation-criteria-in-solid-tumors-)Kriterien, beruhen wesentlich auf der unidirektionalen Messung tumoroeser Laesionen. Aenderungen in der CT-Dichte oder der Anzahl intratumoraler Blutgefaesse werden hierbei nicht beruecksichtigt. Die Positronenemissionstomographie (PET) ist ein sensitives Verfahren zur Erfassung des fruehen und zur Praediktion des laengerfristigen Therapieansprechens auf Imatinib. Die Anwendung der PET ist jedoch aufgrund begrenzter Verfuegbarkeit und der hohen Kosten eingeschraenkt. Modifizierte CT-Kriterien, die sowohl Groesse- als auch Dichteaenderungen beruecksichtigen, sind besonders bei der Evaluation des fruehen Therapieansprechens viel versprechend. Die weitere Optimierung von Responsekriterien sowie Evaluation moeglicher neuer Responsemarker, wie die quantitative Bewertung der Perfusion, koennen vermutlich zu einem verbesserten Monitoring molekularer Pharmakotherapien bei GIST beitragen.

    The comprehensive change from the carbon sources petroleum, natural gas and coal to renewable resources is not possible without research and development. Suitable methods and applications must be developed and continued. Questions of efficiency, environmental friendliness, sustainability, supply of nutrition, public accessibility and use of competition are becoming increasingly important. The brochure under consideration presents promising research findings on plant-based replacement of these carbon sources. It describes ideas of how biomass can be used particularly clean, efficient, and with participation of citizens. Possibilities for the extension of the range of plants, for the mobilization of the waste, for recycling of nutrients, and for the sustainability are described. Only the sustainable use of biomass is future-oriented.

An interreligious research group investigates the perception and interpretation of religion and religious diversity in schools from the perspective of different players in the school. The main focus is set on the question how these patterns of perception and interpretation of religion(s and religious diversity influence the daily life and teaching. Additionally it is of interest, which themes occur in handling this diversity and how people communicate about it. Based on this reasarch, it is aimed to develop methods and models for a diversity-sensitive handling of religious diversity in schools, and to further implement and evaluate these methods and models in a school development project. Besides a theory driven introduction (meaning and relevance of religious diversity in schools, connection to school development, acquisition of competences in religious diversity this article aims to present the used research design (qualitative case study, triangulation of different methods.

Dafuer sollte sowohl der Einfluss der Schlammeigenschaften als auch der Einfluss verschiedener Belueftungssysteme untersucht werden. Zur Beschreibung des Einflusses der Schlammeigenschaften auf den Stoffuebergang sollten Sauerstoffzufuhrversuche mit unterschiedlichen Schlaemmen erfolgen. Durch eine Gegenueberstellung der Ergebnisse der Schlammanalytik mit denen der Sauerstoffzufuhrversuche, sollten die massgeblichen Einflussgroessen ermittelt werden. Dazu sollte die Ueberpruefung verschiedener Analysemethoden auf ihre Anwendbarkeit bei der Beschreibung von belebten Schlaemmen aus Membranbelebungsanlagen erfolgen. Fuer die Untersuchungen zum Einfluss der Belueftungssystems sollten Versuche mit verschiedenen Belueftungssystemen und immer dem gleichen Schlamm erfolgen. Dadurch sollte es moeglich sein Veraenderungen beim Stoffuebergang allein auf das jeweilige Belueftungssystem zurueckzufuehren. (orig.)

    The report presents the preparatory work on the research project of the above title. The first chapter presents a status report on air quality monitoring inside rooms and evaluates the projects so far in which the LuQaS air quality sensor was used. The second chapter is a documentation of preliminary measurements using the LuQaS sensor in two passive residential buildings and several individual measurements for sensor calibration. It was found that in apartments with mechanical ventilation, the sensor reflects the user activities; further, the measured values indicate signal changes also in the off-air of the building, so that control via central sensors in the ventilation and off-air systems appears feasible. The third chapter discusses control strategies for air quality control. Apart from a discussion of control unit types, operating regimes, methods to determine rated values, and additional control functions, the effects of threshold value control with different threshold limit values and volume flow changes on the air quality of a model building was simulated. The results prove the expectation that the air quality inside a building will be influenced positively by air quality control. Theoretical investigations of the DrD method will be presented in another part-report of the project.

    During the past decade measuring and modelling of global and regional processes that exchange energy and water in the climate system of the Earth became a focus in hydrological and meteorological research. Besides climate research many more applications will gain from this effort, e.g. as weather forecasting, water management and agriculture. As large scale weather and climate applications diversify to water related issues such as water resources, reservoir management, and flood and drought forecasting hydrologists and meteorologists are challenged to work interdisciplinary. The workshop 'Modelling of meso- and macroscale river basins' brought together various current aspects of this issue, ranging from coupled atmosphere-hydrology models to integrated river basin management to land use change. Recent results are introduced and summarised in this report. (orig.)

  19. Study on the effects of physical plasma on in-vitro cultivates cells; Untersuchungen zum Einfluss von physikalischem Plasma auf in vitro kultivierte Zellen

    This study focused on the interactions of non thermal atmospheric pressure plasma on in vitro cultured keratinocytes (HaCaT keratinocytes) and melanoma cells (MV3). Three different plasma sources were used: a plasma jet (kINPen 09), a surface DBD (dielectric barrier discharge) and a volume DBD. For analyzing basic effects of plasma on cells, influence of physical plasma on viability, on DNA and on induction of ROS were investigated. Following assays were used: -- Viability: - neutral red uptake assay, cell counting (number of viable cells, cell integrity) - BrdU assay (proliferation) - Annexin V and propidium iodide staining, flow cytometry (induction of apoptosis), -- DNA: - alkaline comet assay (detection of DNA damage) - staining of DNA with propidium iodide, flow cytometry (cell cycle analysis), -- ROS: - H2DCFDA assay, flow cytometry (detection of ROS-positive cells). In addition to the effects which where induced by the plasma sources, the influence of the plasma treatment regime (direct, indirect and direct with medium exchange), the working gas (argon, air) and the surrounding liquids (cell culture medium: RPMI, IMDM; buffer solutions: HBSS, PBS) on the extent of the plasma cell effects were investigated. All plasma sources induced treatment time-dependent effects in HaCaT keratinocytes and melanoma cells (MV3): - loss of viable cells and reduced proliferation - induction of apoptosis after the longest treatment times - DNA damage 1 h after plasma treatment, 24 h after plasma treatment DNA damage was present only after the longest treatment times, evidence for DNA damage repair - due to accumulation of cells in G2/M phase, cell count in G1 phase (24 h) is lower - increase of ROS-positive cells 1 h and 24 h after plasma treatment. It was shown that cells which were cultured in RPMI showed stronger effects (stronger loss of viability and more DNA damage) than cells which were cultured in IMDM. Also plasma-treated buffer solutions (HBSS, PBS) induced DNA damage in HaCaT cells. Direct and indirect plasma treatment caused almost the same effects. A subsequent culture medium exchange diminished the measured effects. It seems to be that next to the kind of liquids and the plasma treatment time the incubation period of the cells with the plasma-treated liquid plays an important role. The plasma-generated reactive species can react with the water molecules and the organic compounds of the culture medium and create long living species (e.g. H2O2) which can interact with the cellular molecules. The other plasma components such as UV light and electric and magnetic fields seem to play only a secondary role in the plasma-cell interaction, because these components come only in contact with the cells during direct plasma treatment and cannot cause the strong effects seen after indirect plasma treatment. The surface DBD used in these studies was applied with air or argon. Argon-generated plasma induced effects on a lower level compared to air plasma effects. Air plasma comprises ROS and RNS in the gas phase. RNS are missing in argon plasma and can therefore not interact with the cells. In addition to the keratinocytes human melanoma cells were treated with the surface DBD (air). Compared to HaCaT cells reduced plasma treatment times resulted in biologically equivalent effects in melanoma cells. The test methods used here are suitable for the biological characterization of new plasma sources or for analyzing plasma-cell interaction of further cell lines. Further investigations should follow e.g. the specification of the plasma induced oxidative DNA damage and the resulting repair mechanisms.

    Full Text Available In den letzten Jahren haben internationale Organisationen wie die EU und die UNESCO eine Reihe von Vorschlägen und Strategiepapieren zur Bildung und Ausbildung im Zusammenhang mit digitalen Medien entwickelt. Mit den dabei entstandenen Rahmenkonzepten der EU (Digital Competence, DigComp sowie der UNESCO (Media and Information Literacy, MIL werden im Kern zwei zusammenhängende Ziele verfolgt: (i digitale Bildung bzw. digitale Kompetenzen, Fähigkeiten und zugehörige Einstellungen umfassend zu kartographieren sowie (ii über die dabei konzipierten edukativ-politischen Rahmenkonzepte Projektförderungen, Bildungs- bzw. Ausbildungsinitiativen sowie Gesetzesvorlagen anzustossen. Tatsächlich sind DigComp und MIL bereits dabei, auf internationaler Ebene einen prägenden Einfluss zu nahezu allen Fragen der Bildung und Ausbildung im Bereich digitaler Medien auszuüben. Beide Initiativen haben innerhalb der genannten Organisationen Leuchtturmcharakter, werden bislang aber von der allgemeinen Öffentlichkeit und der medienpädagogischen Fachöffentlichkeit kaum wahrgenommen. Dessen ungeachtet verbindet sich mit DigComp und MIL jeweils ein impliziter Anspruch auf einen – im Bedarfsfall zu aktualisierenden – Gesamtentwurf zur Analyse und Gestaltung medienpädagogischer Bildung und Ausbildung. Dies gilt für Gesetzesvorlagen, Regulierungen, Forschungsaktivitäten. Sind diese Rahmenkonzepte anschlussfähig an medienpädagogische Debatten über disruptive Versuche, in via soziale Medien geführte öffentliche Debatten einzugreifen, die sich über social bots, fake news oder andere Formen der Einflussnahme manifestieren? Erschliessen sie dazu Reflexionsräume und Handlungsoptionen? Geleitet von diesen Fragen betrachtet der vorliegende Aufsatz, die Rahmenkonzepte der EU und UNESCO, DigComp and MIL. Dabei zeigt sich, dass beide Rahmenkonzepte von Schieflagen gekennzeichnet sind. DigComp und MIL überbetonen die instrumentelle, auf Verwertung am Arbeitsmarkt bezogene Sicht auf digitale Medien - allerdings ist diese Gewichtung bei DigComp stärker ausgeprägt als bei MIL. Obgleich emphatische Appelle zu einem kritischen und reflektierten Umgang mit digitalen Medien weder bei DigComp noch MIL fehlen, bleibt die Ausgestaltung in dieser Hinsicht blass und hat bislang kaum konkretisierende Folgeaktivitäten nach sich gezogen. Bei allen Gesamtentwurfsansprüchen verkennen sowohl MIL und noch stärker DigComp die Rolle sozialer Medien bei der Ermöglichung eines öffentlichen Diskurses sowie ihres Zusammenhanges mit medienpädagogischen Fragen.

    The Bundesministerium fuer Bildung, Wissenschaft, Forschung und Technik (B.M.B.F.-Federal Ministry for Education, Science, Research and Technology) funds the '250 MW Wind' test programme. This programme is designed to acquire statistically relevant data concerning the practical use of wind energy converters (WECs) in the Federal Republic of Germany. The technological and scientific areas of this supportive measure, the 'Wissenschaftliche Mess- und Evaluierungsprogramm' (WMEP - Scientific Measurement and Evaluation Programme), are implemented by the Institut fuer Solare Energieversorgungstechnik (ISET - Institute for Solar Energy Supply Technology) in Kassel. The WMEP acquires and evaluates performance data concerning all funded WECs for a 10 year period. The following areas are the main focal points of the programme: Wind Resources: Local and regional distribution of wind resources in Germany, wind conditions at specific sites. WEC Performance: Energy production and consumption of WECs, periods of grid interconnection, periods of full and partial load, performance characteristics. Reliability: Technical availability, causes of faults, malperformance, component failure. Economics: Income through the operation of the WEC, costs related to maintenance, repair and insurance. Intensive statistical evaluations concerning these focal points are implemented, based on the continuously acquired operational data of each WEC. The results are presented in this report, in a form compatible to the evaluations of recent years. (orig.)

    Nuclear power plants contribute a substantial part to the energy demand in industry. Today the most common fuel cycle uses enriched uranium which produces plutonium due to its {sup 238}U content. With respect to the long-term waste disposal Plutonium is an issue due to its heat production and radiotoxicity. This thesis consists of three main parts. In the first part the development and validation of a new code package MCBURN for spatial high resolution burnup simulations is presented. In the second part several innovative uranium-free and plutonium-burning fuels are evaluated on assembly level. Candidates for these fuels are a thorium/plutonium fuel and an inert matrix fuel consisting of plutonium dispersed in an enriched molybdenum matrix. The performance of these fuels is evaluated against existing MOX and enriched uranium fuels considering the safety and transmutation behaviour. The evaluation contains the boron efficiency, the void coefficient, the doppler coefficient and the net balances of every radionuclide. In the third part these innovative fuels are introduced into a German KONVOI reactor core. Considering todays approved usage of MOX fuels a partial loading of one third of innovative fuels and two third of classical uranium fuels was analysed. The efficiency of the plutonium depletion is determined by the ratio of the production of higher isotopes compared to the plutonium depletion. Todays MOX-fuels transmutate about 25% to 30% into higher actinides as Americium or Curium. In uranium-free fuels this ratio is about 10% due to the lack of additional plutonium production. The analyses of the reactor core have shown that one third of MOX fuel is not capable of a net reduction of plutonium. On the other hand a partial loading with thorium/plutonium fuel incinerates about half the amount of plutonium produced by an uranium only core. If IMF is used the ratio increases to about 75%. Considering the safety behavior all fuels have shown comparable results.

    The thesis deals with a reactive sputter process for the deposition of ITO- films. In contrast to the usual technique, the sputter targets consists of indium-tin-alloy instead of ceramic ITO. All experiments were conducted on an inline coater with 600 mm target-width. The process is stabilized by a control loop based on optical emission detection. The experiments prove, that this control loop guarantees a long term stability of the outcomes of the coating process.Process parameters, that are crucial for the optical and electrical properties of the deposited thin films are identified and studied. Among them are the flow of oxygen and the substrate temperature but also less obvious parameters such as the distance between target and substrate.Througout the work the focus is on the film deposition with pulsed plasmas. Novel bipolar DC pulse- and pulse package generators are employed for the deposition.In order to shed some light onto the influence of certain pulse parameters on the outcome of a particular coating process, a Monte-Carlo-Simulation of the particle flow in pulsed plasmas is developed. This simulation yields the distribution of particles and their respective energies on deliberately placed planes in the process chamber. Particles under investigation are both sputtered species and neutral sputter gas atoms reflected at the target. The results of this simulation provide an explanation for the influence of certain pulse parameters on the outcome of the coating process. The further investigations deal with the influence of the construction of the process chamber on the coating process. For this purpose, locally resolved optical spectra are recorded. In order to analyse these spectra, a novel connected fit algorithm is developed.This algorithm yields the distribution of certain fitparameters on the substrate. Provided the most complex of the discussed parametrizations of the dielectric function are used, these can be crucial properties such as the carrier density or the density of ionised defects. The kernel of this method is an algorithm, that minimizes the difference between simulated and locally measured spectra while considering the film properties in neighboring areas.This technique is then used to compare different designs of sputter chambers and to identify their respective deficits.

    Colloids, i.e. particulates of 1 nm to 1 {mu}m suspended in water, are found in all types of groundwater, either as organic colloids, inorganic colloids, or mixtures of both. Their concentration, chemical composition, structure and particle size varies with the geochemistry of the sediment-water system. Inorganic colloids are Al-Fe-Mn mixed oxides, clays and other complex minerals. Organic colloids consist of humic and fulvic acids which are the main constituent of the dissolved organic carbon. Humic acids are capable of forming metal humate complexes with metal ions via proton-exchanging groups. Radionuclides, too, are transported with humic acid, especially trivalent and multivalent metal ions of the lanthanides and actinides as well as radio-iodine. [German] In allen Grundwaessern werden Kolloide, d.h. im Wasser suspendierte Teilchen mit Durchmessern im Bereich 1 nm bis 1 {mu}m gefunden. Die Zusammensetzung der Kolloide kann sowohl organischer als auch anorganischer Natur sein, wobei in vielen Grundwaessern eine Mischung beider Kolloidarten auftritt. Die Konzentration, die chemische Zusammensetzung, die Struktur und die Teilchengroesse natuerlicher Kolloide variieren stark, sie sind abhaengig von der Geochemie des Sediment-Wasser-Systems. Anorganische Kolloide sind Al-Fe-Mn-Mischoxide, Tone and andere komplexe Mineralien. Organische Kolloide bestehen aus Humin- und Fulvinsaeuren; diese Huminstoffe bilden den Hauptbestandteil des geloesten organischen Kohlenstoffs. Eine wichtige Eigenschaft der Huminstoffe ist ihre Faehigkeit, mit Metallionen ueber protonenaustauschende Gruppen Komplexe - sog. Metall-Humate - zu bilden. Auch Radionuklide, insbesondere drei- und mehrwertige Metallionen der Lanthaniden und Actiniden sowie Radio-Iod werden an Huminstoffe gebunden. Damit koennen Radionuklide nicht nur in Form einfacher Spezies, sondern auch huminstoffgebunden transportiert werden. (orig.)

    The aim of this thesis was the controlled alignment of self-assembled InAs nano-structures on a {l_brace}110{r_brace}-oriented surface. The surface is prestructured with the atomic precision offered by molecular beam epitaxy, using the cleaved edge overgrowth-technique. On all samples grown within this work, the epitaxial template in the first growth step was deposited on a (001)GaAs substrate, while the InAs-layer forming the nanostructures during the second growth step was grown on cleaved {l_brace}110{r_brace}-GaAs surfaces. Atomic Force Microscopy (AFM) investigations demonstrate the formation of quantum dot (QD)-like nanostructures on top of the AlAs-stripes. X-ray diffraction measurements on large arrays of aligned quantum dots demonstrate that the quantum dots are formed of pure InAs. First investigations on the optical properties of these nanostructures were done using microphotoluminescence-spectroscopy with both high spatial and spectral resolution. (orig.)

    Intercultural communicative competence as a global aim of foreign language teaching requires a foreign language teacher profile which takes into account an integration of language teaching and of the development of the learners’ intercultural competence. The paper deals with this issue on two levels. First, it provides an outline of a competence profile of the interculturally competent foreign language teacher. Second, the authors present against this background a selection of findings of an empirical investigation on the self-awareness of German language teachers with regard to the development of intercultural competence as part of foreign language teaching in Croatia. The results show that a basically positive attitude of teachers regarding the integration of intercultural competence into foreign language teaching is confronted with their insufficient familiarity with various aspects of German-speaking cultures and with the use of teaching practices fostering the development of intercultural competence in German language teaching. This, in turn, carries implications for the education and professional development of teachers of German as foreign language.

    In the Lusatian area,Vattenfall Europe AG prosecutes four open-pit minings whose lignite directly is supplied to power stations. A quarter of Germany's total electricity supply is based on lignite. The lignite mining in the area of the Lusatian open-pit minings is particularly efficient due to the horizontal orientation of the Lusatian coal seams. The movable components of the overburden conveyor bridges as well as the bucket wheel excavators and bucket ladder dredgers are subject to a tremendous wear. It is not economically feasible to refurbish certain wear parts. Such parts include Turas corners. In order to refurbish such Turas corners nevertheless, the Austrian company igm robot system AG (Wiener Neudorf, Austria) offers a welding robot.

    Full Text Available The volume edited by Dominik SCHRAGE documents the results of a research seminar held by the editor at the Department of Sociology, Technical University of Dresden, in the spring term of 2004 and fall term of 2004/05. The contributions are based mainly on discourse analysis of print media coverage of the Elbe flood in the summer of 2002. Topics include a reflection on the possibilities of implementing FOUCAULTian discourse theory within empirical research projects, as well as formal characteristics of the flood discourse, the mutual interference between the reports on the election campaigns for the Bundestag and on the flood, and finally the image of nature emerging within the flood discourse. The volume shows the potential of FOUCAULT's discourse analysis for current social events and outlines possible methodological implementations. Moreover, it is a recommended reading for those who are interested in changes in discursive structures within exceptional social circumstances in general and in the social framing of natural disaster in particular.

    District heat is one of Germany's traditional end use energy sources, with a connected capacity of about 57,000 MWth. The heat is distributed via 1,400 grids with a total length of about 19,000 km. The number of households supplied with district heat increased from 9.7 percent in 1993 to 13.7 percent in 2003. About 550 out of about 1,000 German utilities provide district heat to households. During the past few years, the connected capacity of district heating has been stagnating. This is the result of thermal insulation measures, dismantling and abandonment of supply grids, but also of changes on the demand side that can still be compensated by concentration and expansion potentials.

    In order to account for the reactivity-reducing effect of burn-up in the criticality safety analysis for systems with irradiated nuclear fuel (''burnup credit''), numerical methods to determine the enrichment and burnup dependent nuclide inventory (''burnup code'') and its resulting multiplication factor k{sub eff} (''criticality code'') are applied. To allow for reliable conclusions, for both calculation systems the systematic deviations of the calculation results from the respective true values, the bias and its uncertainty, are being quantified by calculation and analysis of a sufficient number of suitable experiments. This quantification is specific for the application case under scope and is also called validation. GRS has developed a methodology to validate a calculation system for the application of burnup credit in the criticality safety analysis for irradiated fuel assemblies from pressurized water reactors. This methodology was demonstrated by applying the GRS home-built KENOREST burnup code and the criticality calculation sequence CSAS5 from SCALE code package. It comprises a bounding approach and alternatively a stochastic, which both have been exemplarily demonstrated by use of a generic spent fuel pool rack and a generic dry storage cask, respectively. Based on publicly available post irradiation examination and criticality experiments, currently the isotopes of uranium and plutonium elements can be regarded for.

    The proposal from the Federal Ministry of Economics and Technology (Berlin, Federal Republic of Germany) to supplement the Law against the Restriction of Competition (GWB) is discussed extremely controversial. The author of the contribution under consideration rejects the reference of the concept to legislative models. In particular, the antitrust laws of the United States of America is misleading. A demand for such a drastic instrument is not visible. Even in the energy sector it could not be applied. A convincing theoretical basis for competition is missing. The author considers the decisive argument against the implementation of those plans in the risk of their political abuse. The author shows in detail that this risk is ubiquitous at all levels of the antitrust law.
