Background: A job-specific Worker's Health Surveillance (WHS) for hospital physicians is a preventive occupational health strategy aiming at early detection of their diminished work-related health in order to improve or maintain physician's health and quality of care. This study addresses what steps should be taken to determine the content of a job-specific WHS for hospital physicians and outlines that content. Methods: Based on four questions, decision trees were developed for physical and psychological job demands and for biological, chemical, and physical exposures to decide whether or not to include work-related health effects related to occupational exposures or aspects of health reflecting insufficient job requirements. Information was gathered locally through self-reporting and systematic observations at the workplace and from evidence in international publications. Results: Information from the decision trees on the prevalence and impact of the health- or work-functioning effect led to inclusion of occupational exposures (e.g., biological agents, emotionally demanding situations), job requirements (e.g., sufficient vision, judging ability), or health effects (e.g., depressive symptoms, neck complaints). Additionally, following the Dutch guideline for occupational physicians and based on specific job demands, screening for cardiovascular diseases, work ability, drug use, and alcohol consumption was included. Targeted interventions were selected when a health or work functioning problem existed and were chosen based on evidence for effectiveness. Conclusion: The process of developing a job-specific WHS for hospital physicians was described and the content presented, which might serve as an example for other jobs. Before implementation, it must first be tested for feasibility and acceptability.

The New Way of Working (NWOW) is changing the world in which we work today. The principles of NWOW are based on freedom of time and place to work, and steering on output (results) instead of input (presence). As NWOW is a relatively new phenomenon, research on the effect of NWOW on knowledge sharing in organizations is scarce. In this research two multiple-case studies were performed to investigate the effect of the New Way of Working on knowledge. In the first study (A) different knowledge sharing scenarios were used at organizations that were in the process of implementing NWOW. This provided the opportunity to compare the sharing of knowledge between 'NWOW workers' and employees that still worked in the traditional way (non-NWOW workers). In total 216 scenario results were evaluated to determine differences in channel choice between the traditional and new work environment. For the second study (B) a Knowledge Sharing Framework was developed, based on the theories of Nonaka and Alavi & Leidner. This framework was used to determine the type of knowledge shared, e.g. tacit or explicit knowledge, in 84 situations. Additionally, to measure the level of NWOW adoption, a NWOW Analysis Monitor was used. The results show that NWOW workers use more different communication channels than traditional workers. When knowledge workers become more mobile, they will exchange knowledge less explicit (codified) and more tacit (personalized), use less face-to-face communication, but more video calls and e-mail. The adoption of the principles of NWOW seems to have a balancing effect on the knowledge that is shared in a tacit and explicit way, which in the view of Scheepers et al. is an effective knowledge sharing strategy. The research results show organizations need to realize that the New World of Working is affecting the way knowledge is shared. Missing out on this development may result in the loss of important knowledge and impact the operation of organizations.

This dissertation are studying the conceptual structure of decision making situation in libraries, by analyzing the library function, decision makings of library and then seeking economic and efficient alternative decision making by programming the· decision making situations, and finally, introducing how to apply management information system or decision making support system. For this purpose, in order to analyzing necessary factors for the decision making system, the questionnaire used Lickert method were distributed to 400 librarians of 36 universities in Seoul by means of mail. 193 librarians, $48\%$ of the questionnaire, are returned are studied by using 'SYSTAT' statistical software to figure out the factors of the decision making system. This dissertation was put six hypotheses and tested with the returned questionnaire. The following five result can be asserted. First, to the higher degree of the librarians' participation in the important library decision makings, the quality of formal library services are improved regardless of seniority of the work. Secondly, the t-test results show that all of t-test scores of seniority of the work, educational background, and responsibilities of the work are exceeding significant level and perception of decision making was proved to be different depending on seniority of the work, educational background, and responsibilities of the work in libraries. Thirdly, as the results of factor af factor analysis, the encouragement on participation in the library academic activities, the extent to get useful information about performances of library and the improvements of library works were grouped by similar posibilities of distribution and therfore the academic activities, the collection of information and the improvement of library performances is proved to be interrelational each other. Fourthly, the fifth hypothesis of the close relationship between the decision making situation and types of advisor by it was more or less interrelational, but their relationship was not seen some significancies. Lastly, as the dynamic organization of library management forming a special commitee or a project team with librarian can improve the extent and quality of the librarian's participation in the decision making of library works, and thus library will become to performance more rational and effective library management.

Purpose: This study was to explore situations that might put the middle-aged Korean-Chinese female migrant workers at risk for work-related musculoskeletal diseases (WMSDs). At the development phase of a continuing health project, the study aimed to clarify health promotion program needs of the migrant population. Methods: A qualitative description research design was used with three focus groups of 23 Korean-Chinese female migrant workers. Each focus group interview was conducted for 70-minutes using semi-structured interview guidelines. The data were analyzed using directed qualitative content analysis techniques. Results: The majority of the participants were household workers and their work included heavy material handling, standing for a long time, and working in awkward postures. They experienced discrimination from employers, lack of control at work, limitations in open-communication, job insecurity, and acculturation. They had needs to have health promotion programs for preventing and managing chronic diseases, depression and menopause as well as WMSDs. Conclusion: The participants were situated in work environments with physical demanding tasks, acculturative and job-related stress and lack of opportunities to participate in health promotion programs. It is suggested to develop a comprehensive program to better meet the needs of middle-aged Korean-Chinese female migrant workers rather than targeting the reduction of WMSDs.

Background: Cardiac pacemakers are known to be susceptible to strong electromagnetic fields (EMFs). This in vivo study investigated occurrence of electromagnetic interference with pacemakers caused by common environmental sources of EMFs. Methods: Eleven volunteers with a pacemaker were exposed to EMFs produced by two mobile phone base stations, an electrically powered commuter train, and an overhead high voltage transmission lines. All the pacemakers were programmed in normal clinically selected settings with bipolar sensing and pacing configurations. Results: None of the pacemakers experienced interference in any of these exposure situations. However, often it is not clear whether or not strong EMFs exist in various work environments, and hence an individual risk assessment is needed. Conclusions: Modern pacemakers are well shielded against external EMFs, and workers with a pacemaker can most often return to their previous work after having a pacemaker implanted. However, an appropriate risk assessment is still necessary after the implantation of a pacemaker, a change of its generator, or major modification of its programming settings.

In many industrial sectors, workers are exposed to manufactured or unintentionally emitted airborne nanoparticles (NPs). To develop prevention and enhance knowledge surrounding exposure, it has become crucial to achieve a consensus on how to assess exposure to airborne NPs by inhalation in the workplace. Here, we review the literature presenting recommendations on assessing occupational exposure to NPs. The 23 distinct strategies retained were analyzed in terms of the following points: target NPs, objectives, steps, "measurement strategy" (instruments, physicochemical analysis, and data processing), "contextual information" presented, and "work activity" analysis. The robustness (consistency of information) and practical aspects (detailed methodology) of each strategy were estimated. The objectives and methodological steps varied, as did the measurement techniques. Strategies were essentially based on NPs measurement, but improvements could be made to better account for "contextual information" and "work activity". Based on this review, recommendations for an operational strategy were formulated, integrating the work activity with the measurement to provide a more complete assessment of situations leading to airborne NP exposure. These recommendations can be used with the objective of producing homogeneous exposure data for epidemiological purposes and to help improve prevention strategies.

본 연구는 간호사의 전문적 업무에 대한 범규범과 임상 현실의 실제적 차이에서 오는 법적 혼란 문제를 외국의 사례와 비교함으로써 이를 비판적으로 고찰하는 것을 그 목적으로 한다. 간호사의 업무 확대의 역사적 배경을 비교하고, 주요 국가의 전문간호사 등의 자격 및 업무에 대한 법적 근거 등을 살펴본 후, 이를 기초로 우리 법제의 발전 방향을 모색하고자 한다. 연구 방법은 비교 제도론적 연구 방법을 적용하였다. OECD 국가 중 미국, 호주, 일본을 선정하여 그 전문간호사 등에 관한 법제를 비교하였다. 미국, 호주, 일본 등에서 간호사의 전문적인 업무는 고령화 사회, 만성 질환, 의사 부족 등으로 인한 의료환경의 변화에 의해 출현하였다. 이들의 전문적인 업무에 관한 법적 근거, 자격인정 및 자격인정제도의 발전과 그 업무 범위 등을 비교하여 살펴보았다. 한국은 미국 등 외국과 비교하여 아직 법적 근거가 부재하며, 전문간호사 등의 업무 범위에 관한 법원의 입장과 실제 업무 간의 격차를 좁히지 못하고 있다. 비교법적 검토를 통해 전문간호사 등에 관하여 한국 실정에 맞는 법안 마련과 업무 범위 개발에 대한 시사점을 줄 수 있을 것이라 기대한다.

본 연구는 수신호 통일지침 개발을 위한 사전연구로 선박작업시 의사소통 수단으로서 수신호 체계의 활용가능성과 표준화 타당성을 검토하였다. 실증연구에 앞서 선박안전관리자의 의견을 수렴하여 수신호 활용가능성이 있는 선박작업활동을 분류하고, 이러한 작업활동 하에 작업자의 수신호 활용의사와 제도적 표준화 선호도를 측정하였다. 통계분석(t-검정, 상관관계분석) 결과 응답자들은 근무형태(선원/육상선박 안전관리감독)와 근무환경(갑판부/기관부)에 관계없이 수신호 소통이 가능한 작업활동에서는 표준화된 수신호 체계를 의사소통 수단으로 적극 수용할 의사가 있었다. 또한, 주어진 선박작업활동 종류에 따라 응답자의 수신호 활용빈도는 유의미한 차이가 있으나 표준화 선호도와는 강한 양(+)의 상관관계에 있었다. 따라서 후속연구로 응답자의 수신호 활용빈도가 높은 크레인 운용, 윈드라스 윈치 운용, 삭류 이동/전달, 화물창 운용 등 항만내 작업활동들을 우선순위로 수신호 통일지침을 설계한다면 선박작업자간 의사소통 개선에 효과적일 수 있다는 결론을 얻었다.
