Ziel der Untersuchung ist es, Indikatoren zu finden, mit denen die Software-Ergonomie im Bürobereich orientierend bewertet werden kann. Eine solche Bewertung könnte im Rahmen einer Gefährdungsbeurteilung nach dem Arbeitsschutzgesetz durchgeführt werden. Die Untersuchung zeigt erstens, dass Beschäftigte selbst in der Lage sind, Defizite im Umgang mit ihrer Software zu benennen. Zweitens zeigt die Untersuchung, dass Beschäftigten im Bürobereich zahlreiche Ressourcen (interne und externe) zur Verfügung stehen. Dabei spielen menschliche Ressourcen in Form der Kollegin / des Kollegen und des/der IT-System-, Benutzerbetreuers/in eine herausgehobene Rolle. Die Belastungen wie auch die Ressourcen beim Umgang mit Computern zeigen sich bei den Beanspruchungsfolgen.
Es wird eine Arbeitshilfe für die orientierende Bewertung von Software-Ergonomie abgeleitet („Checkliste Software-Ergonomie“) mit dem Ziel, unnötige Belastungen und damit negative Beanspruchungsfolgen zu mindern. Die Untersuchung basiert auf einer Online-Befragung aus dem Jahr 2012 mit 397 Teilnehmerinnen und Teilnehmern im Bürobereich. Als statistische Analyse- und Bewertungsverfahren werden die Faktorenanalyse, die nichtmetrische Multidimensionale Skalierung (NMDS) und die multiple lineare Regression eingesetzt.

Model-driven approaches are experiencing an increasing acceptance in the automotive domain thanks to the availability of the AUTOSAR standard, which defines an open software architecture for the model-based development of real-time systems and a corresponding development methodology. However, the process of creating models of existing system components is often difficult and time consuming, especially when legacy code is involved or information about the exact timing is needed. The research community tackles this problem by developing algorithms for automatically deriving characteristics of the system's timing behaviour, e.g., response times and resource blockings from various artefacts such as source code or runtime measurements. This work focuses on reversely engineering an AUTOSAR-compliant model, which can be used for further processing including timing simulation and optimisation, via a dynamic analysis from trace recordings of a real-time system. Although software reverse engineering via dynamic analysis has a long history, little research targets embedded systems and its use for multi-core architectures is largely unresearched. Furthermore, related work mainly discusses the analysis of individual characteristics of a real-time system, such as execution times or stimulation patterns instead of creating a description of the entire system. Huselius, whose work is among the publications most related to the topic of this thesis, proposes a technique to reverse engineer a model that reflects the general temporal behaviour of the original real-time software. However, like other existing solutions, it was not developed with AUTOSAR in mind. It is also not feasible to make this approach applicable to the automotive domain, because Huselius has not considered some required details, such as activation patterns, scheduling information, and compliance to the standardised development methodology of AUTOSAR. We want to tackle this deficiency by introducing, in this work, an approach that seizes on Huselius's considerations and extends them in order to make them applicable to the automotive domain. To do so, we present CoreTAna, a prototypical tool that derives an AUTOSAR compliant model of a real-time system by conducting dynamic analysis using trace recordings. Its reverse engineering approach is designed in such a way that it fits seamlessly into the methodology specified by AUTOSAR. CoreTAna's current features are explained and their benefits for reverse engineering are highlighted, and a framework for evaluating the quality of synthesised models is described. Motivated by the challenge of assessing the quality of reverse engineered models of real-time software, we also introduce a mathematical measure for comparing trace recordings from embedded real-time systems regarding their temporal behaviour and a benchmark framework based on this measure, for evaluating reverse engineering tools such as CoreTAna. This framework considers common system architectures and also includes randomly generated systems and systems of projects in the automotive domain and other industries. Finally, CoreTAna's performance and applicability are evaluated on the basis of this benchmark.

In spite of the good safety records of chemical plants many people regard chemical production as dangerous because of a few major accidents that have occurred. A knowledge of at least the fundamentals of chemical safety technology is indispensable for chemists and engineers working in chemical industry. The increasingly stringent legal and administrative requirements can only be answered by more highly qualified employees. This book combines the author's experience of 15 years of research in the field of chemical safety and 10 years in the chemical industry. It provides newcomers with an easy access to the field and helps practitioners in the chemical industry to answer all questions concerning their daily work with hazardous materials or potentially dangerous chemical plants. The investigation of risks, and preventive measures to be taken to minimize the probability of an accident, as well as its consequences are explained.

Up-to-date, broad-based training for fire service candidates and in-service professionals! Comprehensive coverage--from fire basics to fire department operations- and based on objectives established by the National Fire Academy. Written by experienced fire service faculty from colleges and fire departments, Fundamentals of Fire Protection provides a solid introduction to the full range of fire protection topics. Designed for classroom instruction or self-study, this authoritative resource is a suggested text for the model FESHE curriculum course Principles of Emergency Services (formerly Fundamentals of Fire Protection). It is i deal for students preparing to enter the field or fire protection professionals who want to advance their career. Fundamentals is the only text organized around the Principles of Emergency Services course developed by the National Fire Academy's Fire and Emergency Services Higher Education (FESHE) Conference. Comprised of faculty from over 100 institutions of higher learning with a fire science curriculum, FESHE's model curriculum sets uniform objectives for quality fire and emergency services education. Fundamentals of Fire Protection's 12 chapters are designed for a 12- or 13-week semester of study. Each chapter features measurable educational objectives based on those developed by FESHE, review questions with answer key, and student activities. Easy for instructors to use and for students to understand.

The term 'natural disaster' is often used to refer to natural events such as earthquakes, hurricanes or floods. However, the phrase 'natural disaster' suggests an uncritical acceptance of a deeply engrained ideological and cultural myth. At Risk questions this myth and argues that extreme natural events are not disasters until a vulnerable group of people is exposed. The updated new edition confronts a further ten years of ever more expensive and deadly disasters and discusses disaster not as an aberration, but as a signal failure of mainstream 'development'. Two analytical models are provided as tools for understanding vulnerability. One links remote and distant 'root causes' to 'unsafe conditions' in a 'progression of vulnerability'. The other uses the concepts of 'access' and 'livelihood' to understand why some households are more vulnerable than others. Examining key natural events and incorporating strategies to create a safer world, this revised edition is an important resource for those involved in the fields of environment and development studies.
