Many improper development action were performed at subsurface environment, because there were not any definition about subsurface environment in Korea. The purpose of this study was to establich a definition on subsurface environment. Subsurface environment could be divided by subsurface natural environment and subsurface living environment. The soil, groundwater, ecosystems, landscapes, underground space (naturally occurred) were included in subsurface natural environment. And space and facilities used by human were classified as subsurface living environment.

Objectives: Elevated temperatures during summer months have been reported since the early 20th century to be associated with increased daily mortality. However, future death impacts of high temperatures resulting from climate change could be variously estimated in consideration of the future changes in historical temperature-mortality relationships, mortality, and population. This study examined the future death burden of high temperatures resulting from climate change in Seoul over the period of 2001-2040. Methods: We calculated yearly death burden attributable to high temperatures stemming from climate change in Seoul from 2001-2040. These future death burdens from high temperature were computed by multiplying relative risk, temperature, mortality, and population at any future point. To incorporate adaptation, we assumed future changes in temperature-mortality relationships (i.e. threshold temperatures and slopes), which were estimated as short-term temperature effects using a Poisson regression model. Results: The results show that climate change will lead to a substantial increase in summer high temperature-related death burden in the future, even considering adaptation by the population group. The yearly death burden attributable to elevated temperatures ranged from approximately 0.7 deaths per 100,000 people in 2001-2010 to about 1.5 deaths per 100,000 people in Seoul in 2036-2040. Conclusions: This study suggests that adaptation strategies and communication regarding future health risks stemming from climate change are necessary for the public and for the political leadership of South Korea.

Many legislations have been implemented in order to manage the subsurface environment in Korea. However, there was no control tools for managing subsurface environment so effectively. In this study, many laws and regulations were analyzed for extracting Korean subsurface environment management plan. Korean government need to 1) establish the basic paradigm for building the subsurface space, 2) establish the clear subsurface environment management systems, 3) establish the regulations related with subsurface space compensation, 4) prepare the human health and ecosystem related legislations.

토양 환경은 그 유한성과 다양한 기능의 가치로 인해 중요한 자원으로 인식되고 있다. 따라서 많은 나라에서 토양의 질과 관련된 인자를 활용한 전략환경영향평가를 수행하고 있다. 하지만 우리나라는 아직까지도 오염도 위주의 제한된 인자만을 사용하고 있다. 본 연구에서는 개발기본계획에 대한 전략환경영향평가에서 토양의 복합적 특성을 고려할 수 있도록 개선하고 이를 보금자리주택 공급계획과 도시관리 계획에 시범 적용하였다. 토양을 고려한 전략환경영향평가는 체크리스트 방법을 사용하여 상위계획과의 연계성, 대안 설정·분석, 입지의 타당성을 평가하였다. 평가 결과, 토양 유기물과 토양 침식 항목이 개발기본계획에서 가장 중요하게 고려해야 하는 인자로 도출되었다. 다만, 상기 두 인자에 대한 데이터베이스의 준비, 평가 비용의 증가 등을 예상할 수 있지만, 본 연구에서 개선한 전략환경영향평가 기법은 토양자원 보전에 기여할 수 있을 것으로 기대된다. Soil has been recognized as an important resource due to its finitude and valuable functions. Therefore, many countries have adopted soil quality related indicators in Strategic Environment Impact Assessment(SEIA). However, Korean SEIA has used limited indicators such as soil contamination until now. In this study, the SEIA on "Development Basic Plan" was modified for considering complex characteristics of soil and applied to "Bogeumjari Housing Supply Plan" and "Urban Management Plan". The performance of the SEIA considering soil characteristics was evaluated using a checklist for assessing consistency with upper plan, adequacy of alternatives, and feasibility of siting. Soil organic matter and soil erosion were derived as main indicators for "Basic Development Plans". The proposed SEIA technique equipped with soil indicators is proved to contribute to the soil resource conservation.

본 연구는 메타분석을 활용하여 청소년 멘토링 프로그램의 효과성에 대한 선행연구들의 결과를 종합하여 제시함으로써 청소년의 전인적 발달을 위한 개입의 근거기반 실천적 기초자료를 제공하는데 목적이 있다. 국내에서 발표된 학위논문 및 학술지에 게재된 논문 총 21편의 71개 데이터가 메타분석에 사용되었고, 자료의 분석은 Comprehensive Meta-Analysis 2.0을 활용하였다. 본 연구의 결과는 다음과 같다. 첫째, 청소년 멘토링 프로그램의 효과는 개인내적요인 g=0.819, 진로 및 학업요인 g=1.248, 사회적 요인 g=0.845로, 높은 수준의 평균 효과크기를 입증했다. 둘째, 각 요인별 하위요인 중 개인 내적 요인에서는 자아존중감이, 진로 및 학업 요인에서는 진로계획이, 사회성 요인에서는 학교적응의 평균 효과크기가 가장 큰 것으로 나타났다. 그러나 각 요인별 하위요인 간의 평균 효과크기의 차이는 통계적으로 유의미하지 않았다. 셋째, 이질성 여부를 통계적으로 검증한 결과, 개인 내적요인은 이질성 정도가 낮았다. 높은 이질성을 보인 진로 및 학업 요인은 출판연도, 출판유형, 멘티 연령, 표본 수가 각 개별 효과간의 이질성을 설명했다. 중간 정도의 이질성을 보인 사회적 요인의 조절변인은 멘티 유형이었다. 이러한 결과를 통해 청소년 멘토링 프로그램의 효과를 계량적으로 입증하였으며, 실천현장에서 활용할 수 있는 효과적인 프로그램 구성에 대한 정보를 제공하였다. 또한 청소년 멘토링 프로그램에 관한 개별 연구를 수행할 때 필요한 보완사항을 제안하였다. This study aimed to provide evidence based on interventions for adolescents, utilizing meta-analysis as part of our comparative research into mentoring programs for adolescents. Among articles and dissertations published in Korea, 71 data sets in 22 studies that met the inclusion criteria were reviewed and synthesized. Comprehensive Meta-Analysis 2.0 software was used for the meta-analysis. According to this analysis, first, overall effect size of mentoring programs for adolescents were at a high level(U3=0.800-0.900), and the effect sizes were g=0.819, g=1.248, g=0.845, respectively. The second, although there were differences in the effects size between each outcome of intrapersonal factor, career-academic factor and social factor were not significant, and the largest factor turned out to be self-esteem in the internal factors, course plan in career and academic factors, and school adaptation in the social factors. Third, the moderator factors were found to be the type of publication, the year of publication, the age of mentees, the sample size in career-academic factors, and the type of mentees in the social factors.

Object: This study investigated the effect of self-esteem on depression through family relations satisfaction and tested whether working types would moderate such associations. Method: The subjects were 2,145 elderly who are healthy enough to work and were selected for the ninth Korean Welfare Panel Study. The resulting data were analysed by using the statistical program SPSS 2.1 with reference to steps for testing mediation by Baron and Kenny, moderated mediation by Heyes. Results: Self-esteem has both direct and indirect significant effects, revealing that family relations satisfaction fully mediates the effects of coping strategies of family conflict on depression. From the working types, self-employed/employer and unpaid family worker, moderate the indirect effect of self-esteem on depression through family relations satisfaction. Conclusions: In practical intervention of elderly depression reduction, efforts to increase family relations satisfaction is effective when it is difficult to us address satisfaction. Moreover, we have to provide intervention for elderly with work in context of relationship of individual and familial factor.

Based on successful aging paradigm, participating in social activities for the elderly is becoming important and that depends on available their resources. It is known that selection of a type of social activity appears to depend on the resource of the elderly, so it is necessary to identify under what conditions the elderly will be involved in volunteering or working. This study aimed to identify what factors make the elderly to participate in activities. We used the data from the 12th Korean Welfare Panal Study Wave, which were analyzed by binomial logistic regressions. As the findings, the factors that cause the elderly to participate in volunteering rather than working were education level, age, social relationship satisfaction and gender, among which education level has the greatest impact. This work contributes to prove that the elderly with human and social resources are more likely to participate in volunteering. Based on these findings, we discussed how to encourage elderly to participate in social activities. It needs to the promotion and the information for vulnerable older people to volunteering, especially elderly males. And public and private institutions need to provide educational services to link between network and volunteering for the elderly. In addition, the government should provide support for young-old and old-old adults to be connected to volunteering after retirement.

Environmental impact assessment has been implemented for more than 30 years in Korea. During that period, various amendments were carried out about target plan and assessment factors. However, in current environmental impact assessment act, only a few factors has been considered for soil environment assessment. This study analyzes the national and foreign environmental impact assessment guidelines on soil related factors and figures out the problems and implications of Korean environmental impact assessment. In Korea, water quality, topography and geology, hydraulics and hydrology, and soil contamination were analyzed as a soil related factors. The main assessment targets were pollution related factors such as soil pollution levels, amount of rainfall runoff, and non-point sources. However, in the case of foreign guidelines, soil compaction, soil sealing, and soil salinization is being analyzed for evaluating function and quality of soil environment. The revision of soil-related factors are needed for sustainable development of Korea.
