It is important to identify and evaluate poor working postures properly to prevent work-related musculoskeletal disorders. The purpose of this study is to develope a new upper body micropostural classification scheme for analyzing postural stress in industry. Most of the existing postural classification schemes were based either on the literature, or on simple biomechanical principles, or on a subjective ranking system. The scheme suggested in this study was based on perceived joint discomfort measured through experiment, in which nineteen subjects participated and the magnitude estimation method was employed to obtain subjects' joint discomfort. Also, the criteria for evaluating postural stress of working postures were presented for practitioners of health and safety to be able to redesign working methods and workplaces, which was based on maximum holding time by Miedema and other people. It is expected that the scheme developed in this study could be used as a valuable tool when evaluating working postures.

Objectives : The aim of this study was to investigate whether verbal and spatial working memory functions were impaired not only in patients with schizophrenia but also in people at ultra-high risk for first-episode psychosis. Methods : Twenty-five patients (M 13, F 12) with schizophrenia (SPR), 21 people at ultra-high risk for psychosis (UHR)(M 10, F 11) and 19 normal controls (NC)(M 10, F 9) were recruited. The working memory was assessed by using the verbal and spatial n-back test. The working memory load increased incrementally from the 0-back to the 3-back condition. Results : SPR performed significantly lower than NC and UHR in terms of hit rates of verbal and spatial n-back test. UHR subjects conducted significantly lower than NC and higher in trend-level than SPR in terms of hit rates of verbal and spatial n-back test. These differences were derived from the high working memory load (2-back and 3-back), not from the low working memory load (0-back and 1-back). There was no significant difference between the verbal and spatial n-back test across the three groups. Conclusion : These findings suggest that verbal and spatial working memory dysfunction may be general rather than differential in terms of stimuli modality, and this working memory deficit may be an important trait factor in schizophrenia.

Currently, the departments related to security and secretary service exist in 18 universities and 30 colleges in Korea in order to raise professional security and secretary personnel. Among the 18 four-year colleges in Korea, only two of them have the ethics course include in their curriculum. Also, among the 31 two-year colleges, only three of them have the ethics course included in their curriculum. Besides, as some private security and guardian companies were recently utilized in illegal actions of the rich and ruling class, contradicting their original purpose of existence, many people point out their downfall as a ?forced private army.? As a professional job, if security secretaries take advantage of the knowledge and top-secret technologies and use them for non-ethical purposes, the effect of the damage is far more serious than other fields of jobs. Therefore, taking this event as a turning point, the contract contents and the task area between the client and the security and secretary company must become more transparent in order to prevent illegal actions, and also for the people working in the security and secretary service area, it is necessary to establish a firm ethical consciousness in order to behave appropriately in their working environment. Therefore, this study examines the proper direction of work ethics of the people working in the security and secretary service according to the professionalization of their field, and also aims to propose an appropriate work ethic system such that they will not become an unfortunate victim of various scandals anymore. To do so, the concept of work ethics in professional jobs was examined; and after the code of ethics that reflect the ethical value system of each professional job was reviewed, the study suggested a specific solution for establishing the codes of ethics for security and secretary service.

의료용 사이크로트론은 방사성의약품을 생산하기 위해 양성자를 고속으로 가속시켜 핵반응을 일으키게 되며, 핵반응을 통해 불필요한 중성자가 발생하게 된다. 중성자는 사이클로트론의 부품에 방사화를 일으키는 원인으로 종사자들의 피폭의 원인이 된다. 이에 본 연구에서는 핵반응이 일어나는 Targetry 부품들인 Aluminum body, Silver body, Havar foil의 방사화 정도를 분석하여 피폭선량을 알아보고자 하였다. 실험결과 Aluminum body와 Silver body는 방사화된 핵종들의 에너지가 작고, 반감기가 짧아 종사들에게 미치는 선량이 미미하였으며, 재사용하는데 문제가 없었다. 하지만 Havar foil의 경우 방사화된 핵종들의 에너지가 높고 반감기가 길어 종사자들에게 미치는 영향이 매우 높았으며, 방사성폐기물로써 특별한 관리가 필용한 것으로 나타났다.

본 연구는 근로빈곤층이 빈곤한 주요 원인이 이들이 노동시장에서 겪는 불안정한 경험이라는 점에 주목하여, 이들의 직업력이 어떻게 나타나는지 분석하였다. 이를 위해 사건배열분석과 최적일치법을 활용하여, 근로빈곤층의 직업력을 노동시장 진입 후 일한 기간, 직업 경력에서의 공백의 수와 그 기간, 거쳐 온 직업의 특성을 통해 총체적으로 이해하고자 하였다. 분석결과, 근로빈곤층은 비빈곤층과 비교할 때 일한 기간에서 통계적으로 유의미한 차이를 나타내지 않아 이들이 일을 적게 하기 때문에 빈곤한 것이 아니라는 것을 확인할 수 있었으며, 공백의 수와 기간, 직업의 특성을 통해 살펴본 결과 이들은 비빈곤층에 비해 불안정한 노동경험을 했다는 것을 확인할 수 있었다. 또한 남성과 여성 근로빈곤층 모두는 생애전반에 걸쳐 지속적으로 불안정한 노동경험을 했다는 것을 확인하였다. 이상의 결과를 바탕으로 근로빈곤층을 대상으로 하는 탈빈곤정책에 대해 제언하였다.

The present Study investigated on effect of working time and physical work environment on job satisfaction, and is based on a representative survey carried out in the 15 European Union Member States in 2,000 on behalf of the European Foundation for the Improvement of Living and Working Conditions by Infratest Burke Sozialforschung and a consortium of national fieldwork institutes. In the course of the survey, a total of 21,703 people drawn from the economically active populations in the 15 countries were questioned about their working time, overtime, weekend work, physical work environment, social support of supervisor and co-worker and job satisfaction. Regression analysis and subgroup analysis were employed to examine the hypotheses. It was found that weekend work, overtime and physical work environment associate negatively with job satisfaction. Social support of supervisor and co-worker moderated only relation between working time and job satisfaction. The results provide support for prior quantitative studies partly. Based on these significant research findings, theoretical implications were discussed.

The purpose of this study was to provide basic data necessary for improvement by closely examining factors of having influence upon dental technicians' turnover. Questionnaire survey was conducted of 204 dental technicians who work at dental hospitals, clinics and dental laboratory rooms in Daegu area. The following conclusions were obtained. The satisfaction with job was high in job position in more than co-representative, in the whole and other task, and in less than 9 hours as for working hours. In the satisfaction with working environment, dissatisfaction was high in women, in the working career with 7~9 years, in chief level as for the job position in charge, in being responsible for porcelain in case of the duty field, and in more than 10 people as for the number of employees. The higher satisfaction with job satisfaction and working environment led to the lower turnover intention. Turnover intention was low in case of having ventilation fan & dust collector desk and in case of being well ventilated inside the workshop. As the above results, it is considered to be necessary for arranging institutional device of protecting dental technicians' health and reducing turnover through improving working environment such as forming comfortable environment of using the dust-collecting facilities and the ventilation facilities, wearing suitable individual protective gear and arranging the rest space.

This study was designed to search for the direction to develop housing service which assists the older people to live independently in their community and provides the systematization of community care. The subjects of the research include 533 older people between the age of 60 to 79 residing in Seoul and 84 welfare officials at a dong(in)-office and 67 social workers working at comprehensive social welfare institutions. The results were as follows: Both demanders and deliverers recognized that housing service for older people was necessary for community care, and, in particular, the deliverers had higher degree of necessity as people charged in welfare service. The most needed service was community alarm service which currently is proceeded partially for low-income and living-alone olders. It needed to expand the scope of the people to be served. It appeared that the need for inside safety measures rather than for housing space or structural problems. It requires less effort and cost for those who need simple repair, such as safety grips or slippery protection, and safety checks. Among financial support services, the need for tax benefits appeared the most necessary service for the older people. It suggested that more 'direct' financial support service is needed for the elderly people.
