In dieser Masterthesis wird erforscht wie der jetzige Kenntnisstand der Sicherheitsfachkräfte zu den Themen solare Exposition, Schutzmaßnahmen und die Akzeptanz der Schutzmaßnahmen durch die Mitarbeiter in den Mitgliedsbetrieben der BG ETEM ist. Diese Themen gewinnen an Bedeutung seit die Berufskrankheit Nummer 5103 in den Anhang 1 der Berufskrankheitenverordnung aufgenommen wurde und die BG ETEM nun für ihre Versicherten auch diesbezüglich präventiv tätig ist. Im Rahmen dieser Masterthesis wurde für die Erforschung des Kenntnisstands ein Fragebogen mit zugehörigem Interviewleitfaden selbst entwickelt. Die anschließenden Befragungen wurden durch den Ersteller in den teilnehmenden Unternehmen persönlich für die Masterthesis vorgenommen. Der Teilnehmerkreis beschränkt sich auf interne Sicherheitsfachkräfte, die in Unternehmen der Branche Energie- und Wasserwirtschaft beschäftigt sind. Erforscht werden neben allgemeinen und betrieblichen Angaben ihr Kenntnisstand zu den Themengebieten Gefährdungsbewusstsein, Gefährdungsbeurteilung, Schutzmaßnahmen und der Informations- und Fortbildungsbedarf. Die Antworten werden mit den eigenen Erwartungen verglichen und Rückschlüsse daraus gezogen. Für die BG ETEM werden die Ergebnisse dieser Masterthesis im Hinblick auf den Präventionsauftrag analysiert. Hierzu werden im Rahmen der Masterthesis auch Vorschläge zu diesen Maßnahmen gemacht. So sollen die Beratungen, Informationsmaterialien und Fortbildungen auf die Präferenzen sowie die vorhandenen Wissenslücken in den Unternehmen zugeschnitten werden, um hier berufsbedingte Neuerkrankungen durch solare Exposition langfristig weitgehend zu verhindern.

Vietnam is facing big challenges in terms of environmental pollution caused by natural agents and anthropogenic activities. Environmental pollution in Vietnam is present in air, water and soil environments in many areas with contaminants including total suspended particles (TSP), organic substances, heavy metals, nutrients including ammonium, phosphate exceeding the allowable valuesof national standard. One of the most important causes of environmental pollution is the legal powers of environmental protection organizations, especially the environmental police force, not strong enough. In addition, the awareness of the people about environmental protection is very weak. Improving the system of laws on environmental protection, including sanctions that are strong enough to prevent violations, is of the most importance to enhance the effectiveness of environmental management and protection in Vietnam. On the other hand, educating people and even school children about environmental protection is a very meaningful activity to reduce the pressures and challenges of environmental management and protection in Vietnam. / Việt Nam đang phải đối mặt với những thách lớn về ô nhiễm môi trường gây ra bởi các tác nhân tự nhiên và các hoạt động của con người. Ô nhiễm môi trường ở Việt Nam biểu hiện ở cả môi trường không khí, nước và đất tại nhiều khu vực với hàm lượng các chất ô nhiễm gồm bui thô TSP. các chất hữu cơ, kim loại nặng, các chất dinh dưỡng gồm amoni, phosphat vượt quá tiêu chuẩn cho phép. Một trong những nguyên nhân quan trọng gây ô nhiễm môi trường là sức mạnh pháp lý của các cơ quan tổ chức hoạt động trong lĩnh vực môi trường, đặc biệt là lực lượng cảnh sát môi trường, chưa đủ mạnh. Bên cạnh đó, ý thức của người dân về giữ gìn bảo vệ môi trường còn rất yếu. Việc hoàn thiện hệ thống luật pháp về bảo vệ môi trường bao gồm các chế tài đủ mạnh để ngăn chặn các vi phạm là quan trọng hàng đầu nhằm tăng cường hiệu quả quản lý và bảo vệ môi trường ở Việt Nam. Mặt khác, giáo dục tuyên truyền ý thức cho người dân và thậm chí các học sinh trong trường học về giữ gìn bảo vệ môi trường là hoạt động rất ý nghĩa nhằm giảm bớt các áp lực và thách thức trong quản lý và bảo vệ môi trường ở Việt Nam.

In the last two decades the IT service support worker has emerged to be a worker-type of considerable socio-economic importance. Such workers are symbolic of the trends towards the importance of information/knowledge and information technology within modern economic/political systems. Such systems, heavily influenced by governmental bodies and business organisations, have aggrandised the use of rationalising customer-centric management techniques. And yet such symbolic workers are largely hidden and unacknowledged as a specific type of worker in the business literature. This thesis represents an attempt to conceptualise the IT service support worker as a worker-type, inducing a conceptual model that identifies three aspects to the worker: information systems worker; knowledge worker and service worker and considers them from each of these perspectives. This qualitative research draws on a rich mix of observational and interview data collected across five UK organisations to produce a narrative that suggests that, for different IT service support workers, those different aspects tend to be variably emphasised within their team roles. The study additionally offers a theoretical conclusion that IT service support workers might reasonably be divided into different classes depending upon not only the design of their team role but also their individual career orientations and the nature of the knowledge they actually use in their work. Four such classes are identified as being of particular significance and these are evocatively named: Resigned Robots ; Constrained Careerists ; Establishment Experts and Aspiring Artisans . Whilst being outside of the scope of this study, it is suggested that this novel typology might also be useful for classifying other worker groupings. The study is intended to be useful for the enhancement of IT service management practice and makes several contributions in this regard. These include the need for managers to recognise the importance of experientially-acquired knowledge for efficiency in IT service support work and a suggestion that managers might tailor HRM practices for different classes of worker.

Limnologische Charakterisierung ausgewählter Ackerhohlformen (Sölle) des nordostdeutschen Jungmoränengebietes als Grundlage von Schutzmaßnahmen* *) gefördert durch die Deutsche Bundesstiftung Umwelt und die FAZIT-Stiftung, Frankfurt a.M. 160 S.: 64 Abbn., 24 Tab., 3 gezeichnete Tafeln, 4 mikroskopische Tafeln Humboldt-Universität zu Berlin Institut für Biologie AG Ökologie Die Untersuchungen konzentrierten sich auf das Plankton von Söllen der Jungmorä nenlandschaft Nordostdeutschlands. Ziel war es, die qualitative und quantitative Phyto- und Zooplanktonstruktur verschiedener Sölle unter dem Gesichtspunkt der nterschiedlichen Landnutzung, des Wasserhaushaltes und des Stoffeintrages in zwei Untersuchungsgebieten zu erfassen, mit einem weitgehend ursprünglichen Forstsoll zu vergleichen und daraus Schlußfolgerungen für den Erhalt und den Schutz dieser Kleingewässer abzuleiten. Es wurden sieben repräsentative Sölle monatlich über drei Vegetationsperioden (1994-1997) untersucht. Neben dem Artenspektrum und dem Abun danzwechsel des Phyto- und Zooplanktons erfolgte eine Erfassung des Chlorophyll a -Gehaltes der Mikroalgenzellen, der hydrochemischen und physikalischen Grundparameter und der Pegelstände des Sollwassers. Trotz der großen Individualität der Untersuchungsgewässer konnten aus den Erg ebnissen die Sölle in drei Gruppen statistisch signifikant zusammengefaßt werden. Für deren Abgrenzung sind die Nährstoffverhältnisse (N oder P-Überschüsse, Nitrifikationsgrad), die Sauerstoffsättigungswerte und das Artenspektrum des Phyto- und Zooplanktons bedeutsam. Hohe Leitfähigkeit des Wassers besonders in den Söllen des Gebietes um Lietzen-Döbberin wird durch hohe Sulfat- und Chloridgehalte bedingt. Im Vergleich zu den Seen sind die Chlorophyll a -Konzentrationen als Biomasseäquivalent für die Mikroalgen in Relation zu den Phosphatgehalten auffallend gering. Aus den Ergebnissen lassen sich Maßnahmen zur Erhaltung und dem Schutz der Sölle ableiten. Es wird die konsequente Verminderung der externen Nährstoffeinträge durch die Schaffung und/ oder Pflege von Pufferzonen sowie gegebenenfalls die Umwidmung des Einzugsgebietes in Dauergrünland empfohlen. Weitere Maßnahmen, die auf die Reduzierung der internen Nährstoffreserven zielen, sind erst nach zusätzlichen Untersuchungen insbesondere zum Phosphorbindungsvermögen der Sedimente für die Sölle ableitbar. / Limnological characterization of selected ponded depressions of the north German young moraine site as a basis for conservation* *) sponsored by the Deutsche Bundesstiftung Umwelt and the FAZIT-Stiftung, Frankfurt a.M. 160 S.: 64 Abbn., 24 Tab., 3 graphic Tables, 4 microscope tables Humboldt-Universität zu Berlin Institut für Biologie AG Ökologie The main geographical feature of the ground and terminal moraines of northern Germany are the numerous small depressions, many of which are water-filled. They represent a typical geographical element of this region and in the German language are usually referred to as "Sölle" (Singular = "Soll"). These small bodies of water were created either glacially through the melting of dead-ice pieces (natural depressions or dead-ice depressions) or later (circa 12th or 13th century) in the course of the clearing of large tracts of forested land through the partial and permanent damming of depressions (pseudo depressions). The study concentrated on the plankton levels of ponded depressions in the recent moraines of northern Germany. The goal of the study was to record the qualitative and quantitative phytoplankton and zooplankton make-up of several different ponded depressions with consideration of the various land uses, management of water, and introduction of nutrients in two research areas and to compare these findings with a mostly unaltered forested ponded depression (ponded depression in a forested area) for the purpose of deriving conclusions about the preservation and protection of these small water ways. Seven representative ponded depressions were examined monthly over the span of three vegetation periods (1994-1997). In addition to the variety of vegetational species and the variation in amounts of phytoplankton and zooplankton, data about the amount of chlorophyll a in the micro algae cells, the hydro-chemical and physical ground parameters, and the water level of the ponds was recorded. In spite of the considerable uniqueness of each of the ponds under examination, the results of the study allowed for the classification of the ponded depressions into three statistically significant groupings.The proportions of nutrients (a surplus of N or P or the level of nitrification), the oxygen saturation values, and the vegetational spectrum of phytoplankton and zooplankton proved meaningful for the differentiation of the groupings. High conductivity of the water, especially in the ponds in the area around Lietzen-Döbberin, is caused by high levels of sulfate and chloride. In comparison to lakes, the concen trations of Chlorophyll a as a biomass equivalent for the micro algae are noticeably smaller in relation to the phosphate levels. The results of the research suggest measures for the preservation and protection of the ponded depressions. The intentional reduction of external nutrients through the creation of and/or care for buffer zones and, if necessary, the redesignation of areas zoned for development into permanent nature conservation zones is recommended. Further preservation measures, aimed at reducing the reserves of internal nutrients, will only be deduced after further study of the ponded depressions, especially in relation to the ability of the sediment to absorb phosphors.
