This study is to examine current child care support policies and their limitations and to make some suggestions by means of statistics and previous literature. Major findings are as follows: First, As the women have younger children, the effect is more negative. Second, a maternity leave of Korea is 90 days, which is below ILO standard. Moreover, it is not well supported by the companies they work for. Third, the increasing number of men has spent a paternity leave since the pertinent law was enforced in 2001. The rate of spending the leave, however, is not as high as expected, because it has not yet been decided whether the leave would be paid or not. Lastly, the number of the employer-supporting child care center is rather few due to the legal standard of the facility and the expense that a company should cover. Only 46.5% of the companies that has been appointed to obligatorily establish the center now operate the facility. Therefore, child care support policies should be reformed or improved to help reduce married women's child care burden obviously hindering women from being employed, and this will consequently promote their economic activities. It is also urgently required to expand the application of the parental leave in terms of both object and scope. It is important that employers and employees get ready to compromise each other on the wage issue during the leave. In addition, the flexibility in period and form of the parental leave and the connection of working places with local community for better child care service must be taken into consideration.

Sustainable development is generally defined as an approach that 'meets the needs of the present without compromising the ability of future generations to meet their own needs' (World Commission on Environment and Development: WCED, 1987, p. 43). The sustainable development is a holistic concept that encompasses three aspects: environmental protection, economic development, and social contribution. From the sustainable development perspective, environmental management must consider contributions to other economic and social aspects. In this sense, it differs from narrowed environmental management which focuses on only environmental impacts, and a well-being concept in Korea that mainly appeals to health. Recently, leading apparel firms, such as Nike, Otto, and Marks & Spencer, are increasingly adopting the environmental management to achieve the future competitive advantage. The environmental management can be achieved through integrated supply chain management. Despite of flowing importance of environmental supply chain management in practice, academic attention to this area has been seriously lacking. This study regards the environmental management by the sustainable development perspective as a solution for Korean apparel firms to solve their current sluggish growth. The purpose of this study was to provide Korean apparel firms with guidelines toward the environmental management based on extensive literature reviews and case studies. The paper started with two important research frameworks, the sustainable development and the environmental supply chain. Within the frameworks, the leading cases of the environmental management of Korean and foreign apparel firms were analyzed. Both macroscopic and microscopic applications of the environmental supply chain management for Korean apparel firms were suggested based on the analyses.

추격형 기술개발과정에서는 개발해야 할 기술이 이미 존재하고 있기 때문에 기술개발의 불확실성은 상대적으로 낮았다. 그 기술이 개발가능하다는 것, 그리고 특정의 설계 방식을 갖추어야 한다는 것을 알 수 있었기 때문이다. 그러나 탈(脫)추격 단계에서의 기술혁신은 많은 경우 모방할 대상이 없으며, 또 그 기술이 개발 가능한 것인지도 사전적으로 알기 어렵다. 따라서 탈(脫)추격 단계에서 기술혁신을 성공적으로 수행하기 위해서는 불확실성에 대한 새로운 접근 방식이 필요하다. 이 글에서는 탈(脫)추격 단계에서 나타나는 기술 경제적 불확실성 관리의 핵심을 기술적 불확실성에 대한 대응과 정당성 확보라는 요소로 정리하고, 대응방안을 모색하는 개념적 틀을 제시하고자 한다.

In power system research fields, one of current key issues is the construction and commercialization of micro grid site which is called green island, carbon zero island, energy independent island, building micro grid, etc. and various affiliated technologies have been being vigorously developed to realize. In addition, various researches about electric vehicles (EVs) are in progress and it is expected to penetrate rapidly with the next a few years. Some new load models should be developed integrating with electric vehicle loads because the EVs' deployment could cause the change of load composition rate on power system planning and operations. EVs are also resources for micro grid as well as distributed generation and demand response so that various supply and demand side resources should be considered for micro grid researches. In this paper, the load composition rate of residential sectors is prospected considering the deployment of EVs and the resource configuration of micro grid is optimized based on net present cost. In the optimization, the load patten of case studies includes EV's charging characteristics and various cases are simulated comparing micro grid environment and normal condition. HOMER is used to compare various cases and economic effects.

This study was carried out to understand the formation of acid mine drainage (AMD) by pyrophyllite (so-called Napseok)-rainwater interaction (weathering), dispersion patterns of heavy metals, and patterns of mixing with non-polluted water in the Tongnae pyrophyllite mine. Based on the mass balance and reaction path modeling, using both the geochemistry of water and occurrence of the secondary minerals (weathering products), the geochemical evolution of AMD was simulated by computer code of SOLVEQ and CHILLER. It shows that the pH of stream water is from 6.2 to 7.3 upstream of the Tongnae mine. Close to the mine, the pH decreases to 2. Despite being diluted with non-polluted tributaries, the acidity of mine drainage water maintains as far as downstream. The results of modeling of water-rock interaction show that the activity of hydrogen ion increases (pH decreases), the goncentration of ${HCO_3}^-$ decreases associated with increasing $H^+$ activity, as the reaction is processing. The concentration of ${SO_4}^{2-}$first increases minutely, but later increases rapidly as pH drops below 4.3. The concentrations of cations and heavy metals are controlled by the dissolution of reactants and re-dissolution of derived species (weathering products) according to the pH. The continuous adding of reactive minerals, namely the progressively larger degrees of water-rock interaction, causes the formation of secondary minerals in the following sequence; goethite, then Mn-oxides, then boehmite, then kaolinite, then Ca-nontronite, then Mgnontronite, and finally chalcedony. The results of reaction path modeling agree well with the field data, and offer useful information on the geochemical evolution of AMD. The results of reaction path modeling on the formation of AMD offer useful information for the estimation and the appraisal of pollution caused by water-rock interaction as geological environments. And also, the ones can be used as data for the choice of appropriate remediation technique for AMD.

Recently, concern about family safety is rising again as an important issue with the context of family healthiness and well-being in Korean society despite of the dramatic economic growth. The purpose of this study is to examine the status of family safety of singles and single-parent households and to investigate the effect of social capital on the level of their family safety. Data are from the 10th wave of Korea Welfare Panel Study analysing one-person households(N=2,017) and single-parent households(N=172). One-person households were categorized as three groups by age(the youths/middle-aged/the elderly) and single-parent households were also three by family types(mother-child/fahter-child/grandparent-child). The major results were as follows: First, the mean of family safety index was highest among middle-aged, while single youths had the fewest problems in terms of family safety. Second, social capital was found to vary by family structure. In the one-person households, all the levels of the social capital variables, including trust, bond, acceptance, and participation, differed significantly; only two variables, bond and embracement, differed in the single-parent households. Third, social capital differed between the low-income households and others significantly. Forth, the positive effects of social capital on overcoming family safety problems were investigated. In conclusion, social capital represents an alternative resource for overcoming economic hardship for low-income one-person/single-parent households, especially for middle-aged singles and father-child single-parent households. Based on these empirical results, theoretical implications were discussed with regard to family policy and programs.

이 논문은 지난 10여 년간 우리나라가 채택한 산업클러스터 정책의 평가에 기초하여, 이 정책이 창조경제 실현을 목표로 하는 시대에서도 유효한 정책이 될 수 있을 것인지를 검토하고 향후 정책방향을 제시하기 위한 목적으로 작성되었다. 그동안의 산업클러스터 정책은 산 학 연 네트워킹의 개선과 혁신기반의 강화로 생산성 증가에 기여했지만, 정부 주도의 인위적 클러스터 만들기 정책으로 인해 개방적이고 유연한 클러스터의 발전이 이루어지지 못한 문제가 있었다. 산업클러스터는 창의성에 의한 혁신 유발과 가치창출이라는 창조경제의 선순환에 기여할 것으로 보았다. 그 효과를 극대화하기 위한 향후 정책방향으로서 지리적 집중과 상호 연계라는 클러스터의 본질에 충실할 것, 창조성이 보장되는 클러스터를 만들 것, 국지적-세계적 전략을 결합한 다중 스케일의 산업클러스터를 지향할 것, 지역정책과 산업정책 부문 간의 정합성을 확보할 것 등이 제안된다.

Rapid social change affects residential environments and this in turn creates new stimuli to which people have to adapt. These stimuli have been seen to increase stress levels. Therefore, dwellers in these environments try to reduce stress through various methods. The purpose of this paper is to: 1) identify the general trends of coping styles about residential environmental stress, 2) analyze the differences in socio-demographic characteristics and how the physical characteristics of buildings affect stress, find out how personal backgrounds affect stress levels and the ability to get rid of environmental-related stress. The subjects in this study consisted of people living in multi-family housing in Gwangju. The city is divided into 5 districts and used quota sampling. 324 housewives were surveyed from the households by self-administered questionnaires. The survey was conducted in December, 2006, after the questionnaire was revised based on the results of preliminary survey. After all the questionnaires were collected, the data was coded and analyzed using the SPSS 12.0 program. This study confirmed that the manner in which those in multi-family housing coped with stress. Especially, we need a policy which seriously considers residents who are of low social-economic standing. As well as being exposed to residential environmental stress, they also have no means to deal with it. The age of a building had a strong impact on coping styles about residential environmental stress. We have to make special studies about the adaptive reuse of buildings for the reduction of residential environmental stress and to greatly improve coping styles. In conclusion, it emphasized the importance of education, information, and economic aid. Reasonable housing management would surely lead to a rise in residential satisfaction and the promotion of residential welfare.

In aging Korean society, many elderly people have difficulty in the areas of health, economic insecurity, role-loss(both work & spouse), loneliness, and family conflicts. Above all, retirement from work is one of the most important stressful life events having influences an elderly's persons economic & social activities, mental state, health status, and Lifelong educational programs could help the aged cope with these situations in later life. Health and social welfare are commonly recognized as an important value of life. They also have an effect on each other. Most people agree that the promotion of health and social welfare is to take a short-cut toward achieving well-being. Thus we need to develop a substantially integrated program of lifelong education, before and after retirement, for the promotion of health and welfare. Universities have the advantage of practicing lifelong educational programs because they have more material, intellectual, and human resources than any other educational facilities. As a result, the purposed of this study is to suggest life-long educational programs for promoting both health conditions and the level of social welfare by utilizing an aging center affiliated with a university. Specifically, the developmental courses of pre-retirement, learning in retirement, elder-hostels, and the connection between pre and post-retirement educational programs are proposed in this study.
