Purpose: This study was conducted to investigate the recognition on center-based child care health programs for parents with ill children. Methods: Cross-sectional descriptive study with convenient sampling method was used and 136 parents were recruited from two university hospital outpatient departments and hospitalized wards, and they completed a structured questionnaire. Results: Majority (57.4%) of parents experienced a leaving work early or being absent from their work due to children's illness. Most dissatisfying factors in child care centers were child health management. Most of parents agreed on the need for a center-based child care health program, and wanted a better management of health care by health professionals in child care centers. Conclusion: These results support that there is a great demand for center-based child care health programs. These special programs are needed for reducing a child rearing burden for working mothers and overcoming the low birthrate in Korea. Health-care programs in child-care settings can help parents meet the health needs of their children while reducing absenteeism from work, thereby contributing to job stability. These results suggest discussions of the related policy with child care centers responsible and national health and educational authorities.

Objectives : The purpose of this study was to analyze the types of hospitals participating and the factors influencing comprehensive nursing service. Methods : Data were gathered from 231 hospitals offering the comprehensive nursing service in 2016. Collected data were analyzed using the multinomial logistic regression with the SPSS 24 version program. Results : First, factors influencing the types participating comprehensive nursing services were identified as hospital type, number of beds, medical doctor and, nurses per bed. Second, if all tertiary hospitals, general hospitals and hospitals participated in the service, approximately 122,022 ~ 166,274 nurses would be needed for the service. Conclusions : Hospitals providing the comprehensive nursing service will be expanded gradually. As such, thoughtful policy considerations are required to successfully establish services, such as improvement in hospitals, required nurse staffing level and demand and supply of nurses. Therefore, it is necessary to control the participation ratio of hospitals in consideration of the various circumstances.

This paper presents a portfolio model for a long-term power generation mix problem. The proposed portfolio model evaluates generation mix by considering the tradeoffs between the expected cost for power generation and its variability. Unlike conventional portfolio models measuring variance, we introduce Conditional Value-at-Risk (CVaR) in designing the variability with aims to considering events that are enormously expensive but are rare such as nuclear power plant accidents. Further, we consider uncertainties associated with future electricity demand, fuel prices and their correlations, and capital costs for power plant investments. To obtain an objective generation by each energy source, we employ the sample average approximation method that approximates the stochastic objective function by taking the average of large sample values so that provides asymptotic convergence of optimal solutions. In addition, the method includes Monte Carlo simulation techniques in generating random samples from multivariate distributions. Applications of the proposed model and method are demonstrated through a case study of an electricity industry with nuclear, coal, oil (OCGT), and LNG (CCGT) in South Korea.

Most decision makers in the electricity industry plan their electric power expansion program by considering only a least cost operation, even when circumstances change with differing complexities. It is necessary, however, to analyze a long-term power expansion plan from various points of view, such as environmental friendliness, benefit of a carbon reduction, and system reliability, as well as least cost operation. The objective and approach of this study is to analyze the proper role of nuclear power in a long-term expansion plan by comparing different scenarios in terms of the system cost changes, $CO_2$ emission reduction, and system reliability in relation to the Business-As-Usual (BAU). The conclusion of this paper makes it clear that the Korean government cannot but expand the nationwide nuclear power program, because an increased energy demand is inevitable and other energy resources will not provide an adequate solution from an economic and sustainability point of view. The results of this analysis will help the Korean government in its long-term resource planning of what kinds of role each electric resource can play in terms of a triangular dilemma involving economics, environmental friendliness, and a stable supply of electricity.

As domestic buildings have been large-scaled, diversified and high-rise, there have been a consistent demand for design, development of construction technology and accident prevention activity as well as quality enhancement. In spite of governmental and related institutions' efforts for reducing national losses which come from numerous accidents, there have been endless small and large accidents on the construction site and thus, it is urgent to conduct empirical researches in this area. Currently safety supervision system in construction industry has enforced harm and danger prevention planning system, however it merely stick to other existing materials. In addition, it is difficult to put it into practice in that it requires bearing too much burden to draw out the planning itself in a case of large construction work. Consequently in this paper we select evaluation criteria by construction progress, classify into several categories, and regard potential danger which often occurs, as a evaluation criterion. Further step is to allow workers or collaborated companies to express their expert opinions or experiences and to encourage quality and process control and autonomous safety control by applying PSM method. The reason why PSM method should be quantitative and substantial progress is because it contributes Korean constructing companies to enhancing their safety control ability and to taking an equal stance just like developed countries,' thereby strengthening there competitive edges. Boost of safety control system by PSM method will make an enormous contribution to preventing construction accidents on the site by establishing and securing an autonomous safety control system.

The National Competency Standards(NCS) has been developed a good curriculum to reflect the demand in the industry. NCS is defined as systemizing the knowledge, skill, and attitude required to perform a task in the industry. It is an effort to reduce the gap between educational requirements and occupational requirements. However, when NCS is applied, the task level is changed to the title of qualification according to the policy outcomes for the government project. And, the NCS has been emphasizing the purpose of license acquisition, rather than using the standard for tasks in the industry. It means that the misuse of NSC hinders utilizing it as the original purpose of standardizing a task. It requires the customer to study the required competency unit with a no-choice option. Moreover, it makes it hard for companies or industry autonomically run the NCS. Therefore, we define the operational range in terms of the education field, the qualification field, and the career field to diffuse and apply NCS, and suggest the effective utilization method.
