In Korean cases, the occupation of building construction is below 10% of the total industry workers but from a accident rate point of view, it is a risk serious industry and it's hazard is very considerable which accident rate is up to 30% of the total industry workers. The reason of high accident rate of the building construction is its own characteristic, hazard of the work in which is implicated and the shortage of safety counter plan and information, so it is most required to the building construction that educating, training, short and long period approaching to prevent the hazard. The safety information of building construction which is related to safety accident is divided into human and material such as hazard, work situation, cause and counter plan. The existing hazard cases imply all of the information about the work type and work progress of the building construction, so if the research of the every fact is well accomplished, we can obtain the useful information and prevent the hazard of building construction. From this point of view, the emphasis of this study is based on analyzing the cause of hazard first, suggesting the safety information each part of work type and work progress second, and finally making the all existing hazard cases to the Data Base and developing the safety information system.

This study investigates the balance between work and family, and the happiness of married working women who have preschool-aged children. Data were collected from 321 questionnaires that consisted of three parts: 1) basic demographic variables, 2) family-life variables, and 3) working-life variables. SPSS 21.0 was used for the statistical analysis. The variables that were identified to have a statistically significant impact on the balance between work and family were income, age of first child, time spent on housework and childcare on weekdays, time spent on housework on weekends, family-friendly service in the workplace and flexibility of work schedule. 2) The variables that were identified to have a statistically significant impact on happiness were age, income, time spent on housework on weekends, satisfaction with spouse's participation in housework and childcare, average working time, family-fiendly service in the workplace, flexibility of work schedule, and balance between work and family. The majority of the variables that influence balance between work and family, and happiness related to aspects of work, such as family-fiendly service, flexibility of work schedules, and average working time. The results also found that the load of housework and childcare on weekends is a heavy burden for working women. Further research needs to focus on developing the extending index of happiness including the measure of balance between work and life. In addition, further studies with more varied groups need to be conducted.

The rise of music resources has led to a parallel rise in the need to manage thousands of songs on user devices. So users have a tendency to build playlist for manage songs. However the manual selection of songs for creating playlist is a troublesome work. This paper proposes an auto playlist generation system considering user context of use and preferences. This system has two separated systems; 1) the mood and emotion classification system and 2) the music recommendation system. Firstly, users need to choose just one seed song for reflecting their context of use. Then system recommends candidate song list before the current song ends in order to fill up user playlist. User also can remove unsatisfied songs from the recommended song list to adapt the user preference model on the system for the next song list. The generated playlists show well defined mood and emotion of music and provide songs that the preference of the current user is reflected.

This study investigate the balance between work and family of married working women. Data from 12 married working women who have child(ren) in age 7-9. was collected through in-depth interviews. The interviews was to examine their child-caring and the balance between work and family. The results show that the child(ren)'s age, the quality of after school program, the time to go to work and out of work, the type of work and labor flexibility were the important factors which affect the everyday child-caring. The respondents were unsatisfied with their balance between work and family, especially they felt that their leisure time is insufficient, but they seemed to accept this unbalance to some extent because they recognize the child-caring is more important than their balance between work and family in this life cycle. In conclusion the public support for the child-caring of dual-earner families with the child(ren) in lower grades has to be more extended because the support system and services for this life cycle are weak and insufficient compared with the support system for the child(ren) of the preschool ages. The currently public services for child-caring are still far from their needs to achieve the balance between work and family. So the whole child care support policies and systems are to be continued with more balanced perspectives and practical programs.

This study seeks to identify the reform of vocational education plans so as to bring about a seamless transition from school to work. It puts forward a number of suggestions based upon an analysis of vocational education policies in Korean and U.S. schools, concerning the government's role, partnerships between education and industry, the educational system, curriculum and work-based learning. First, not only government initiatives but also close partnerships between education and industry are essential to help vocational education in school the transition to employment. Education and industry should work closely together to standardize certificate related skills and to have these skills reflected in the curriculum. Also the government should strive to provide guidelines for work-based learning and formulate standards for supervision and evaluation. Second, to facilitate the school to work transition, comprehensive schools should be promoted so that students have access to a greater ranger of vocational education. At the same time, an assessment system that certifies a mastering of the basic skills of those who undergo the education should be introduced, and it should be related to earn these certificates. Third, standardized vocational skills should be included in the curriculum so that students can acquire skills that are useful for industry. All the students in vocational and general high schools should have access both to general education, the foundation for lifelong learning and for employ ability, and to basic occupational skills which empower students in dealing with rapid changes of technology. Also a range of specialized vocational curricula should be offered so that students can opt for more specialized occupations; and they can select careers appropriate to their capability. Fourth, so that all students to have the opportunity to take part in work-based education, which is closely related to employment, various work-based learning programs should be offered to meet the needs of students and their educational conditions. Companies should for their part train students thoroughly in accordance with the standards of work-based education. In addition, supervisors should be stationed both in schools and companies in order to administer the students' work-based learning.

Many automobile assembly workers often do several cycles of tasks continuously, i.e., without breaks, to get a longer break. This is not recommended since the dose of fatigue increases exponetially with time and it takes much longer time to recover. In this study, a laboratory experiment was conducted to investigate the effect of work/rest schedules on workload of a repetitive upper-limb task. Eleven male subjects participated in the experiment, in which simulated screw driving tasks were carried out repetitively with 3 different work/rest schedules: standard breaks(1 cycle of work at a time, 60 20-s breaks), medium breaks(5 cycles of work at a time, 12 100-s breaks), and long breaks(10 cycles of work at a time, 6 200-s breaks). The result showed that medium- and long-breaks schedules significantly increased the level of perceived discomfort and %HRR as compared to the standard-break schedule. The subjects' preference was not statistically different among work/rest schedules, which might be caused from the absolutely low level of workload of the experimental tasks. From the results, it is recommended to have frequent and shorter breaks rather than infrequent and longer breaks to decrease the level of physical workload. A more expanded studies, however, should be carried out to provide more practical safety guidelines on the work practice of continuous working without breaks among automobile assembly workers.

Nuclear power plants(NPPs) are consisted of power production functions and safety functions preventing leakage of radiation. Operators working in NPPs shall maintain these functions during an operation period through various activities such as improvement & modification, corrective maintenance, preventive maintenance and surveillance test. According to the performance of these work activities, there are configuration changes in NPPs systems. Its changes cause the increase of safety risks(CDF) and plant trip risks. Recently, the importance of risk management is increasing gradually in the operation process of NPPs. Therefore, this paper presents the work management methods using the various risk monitoring systems during power operation and overhaul period. Also this paper suggests the optimum application ways of risk systems for work management.

The IAEA held the IAEA Robotics Challenge 2017 (IRC2017) to protect workers during inspections of spent nuclear fuel and to improve work efficiency and accuracy rates. To this end, we developed an unmanned surface vehicle (USV) system called the spent fuel check vehicle (SCV). The SCV extracts and tracks the target through image processing, and it is necessary to find suitable parameters for the SNF storage environment in advance. This preliminary work takes time. It is also difficult to prepare the environment in which the work will proceed. In addition, if the preliminary work does not proceed as planned, the system will not move at the proper speed and will become unstable, with yawing and overshoot. To solve this problem, we developed a controller with a camera that can extract the depth at which the target is stored and allow distance-adaptive control. This controller is able to attenuate system instability factors such as yawing and overshoot better than existing controllers by continuously changing system operation parameters according to the depth. In addition, the time required for preliminary work during inspections can be shortened.

Purpose: The purpose of this study was to identify the frequency and duration of primary health practitioners' work, and their job satisfaction, and to confirm differences in work and job satisfaction by type of primary health care post. Methods: Work frequency, duration of work, and job satisfaction were estimated by 371 primary health practitioners. Chi-square test and t-test were used to identify the differences in working patterns and job satisfaction by type of primary health care post. Results: Primary health practitioners were found to spend more time working with the elderly population than with students, pregnant women, children, people with disabilities, and multicultural families. Those in costal areas were more concerned with students than those working inland. In the latter group of practitioners, more time was spent working with patients with chronic diseases, pregnant women, women, children, multicultural families, and mental health clients. Also, the job satisfaction of inland primary health practitioners was significantly higher than that of costal practitioners. Conclusion: It is necessary to identify the characteristics of primary health practitioners' work, focusing on changes in the medical service environment. Furthermore, it is necessary to provide job training according to type of primary health care post, as practitioners' approaches should differ between posts.
