The increasing trend of the five violent crimes (murder, robbery, rape, violence, theft) in Korea is not independent of social and economic factors. Several social science research have discussed about this issue but most of them do not properly reflect the nature of the time-series data. Based on several time series models, we studied about the endogenous factors (time, seasonal and cycle factors) and exogenous factors (economical, social change and crime control factors) on violent crime occur in Korea. Autocorrelation were also taken into account. Through this study, we want to help to make preventive policy by explaining the cause of violent crime and predicting the future incidence of it.

전 세계의 녹조관련 전문가들은 녹조를 제어하는데 있어 특효약은 없으며, 모든 수역에서 효과를 보이는 보편적인 대책도 없다고 지적하고 있다. 따라서 녹조 저감을 위해서는 해당 수역의 유역환경 및 수환경 특성에 대한 다학제적 연구를 바탕으로 각 수역의 정치, 경제, 사회, 기술적인 면을 고려한 종합적인 대책 수립 및 시행이 필요할 것이다.

전력계통 가운데 중요한 역할을 담당하고 있는 대용량 전력용변압기는 효율이 높고 그 특성이 매우 안정되어 있는 설비이나 절연유의 여과와 같은 보수작업에도 불구하고 점진적인 열화과정이 누적진행되며 결국에는 교체를 필요로 하게 된다. 이러한 교첵 적절한 시기에 이루어지지 않는 경우 불시의 고장현상 또는 사고가 발생하게 되어 전력계통뿐 아니라 사회적 경제적으로도 큰 문제를 야기한다.

This study analyzes previous research on 'The Self-Governance of the Commons' to overcome 'The Tragedy of the Commons', and derives elements for successful commons management. These factors are compared and analyzed with the social and economic attributes of the Jeju Haenyeo community, a successful community self-governance model. In addition, in the recently changing environment, it is revealed whether this internal community mechanism can be useful in the future. The goal is to reveal what social and economic factors will help the sustainability of the Jeju haenyeo community in the future. As a result of analyzing the internal operating mechanism of the Jeju haenyeo community, the production and distribution system that improves trust and reciprocity, the inherent sense of community, the division of roles between formal and informal organizations, and the institutionalized explicit and implicit norms within the organization served as internal and external strengths of community sustainability. However, the closure of the network, the crisis of productivity, the weakening of homogeneity, and the emergence of new subjects acted as internal and external weaknesses. In conclusion, for the sustainability of the Jeju Haenyeo community, it is necessary to reorganize the reproductive function of labor using the haenyeo school, to maintain clarity on the subject of livelihood and cultural transmission, and guarantee the income of Haenyeo.

This study analyzes the perception of the old age life effects on the preparation for old age plan for veterans who are somewhat isolated from our society in spite of the increasing importance of the old age plan due to the rapid population aging society in Korea. The result of the study shows that meaningful differences in terms of characteristics of sociology of population are rank, level of education, religion, composition of family members in old age life plan in two parts(economic, leisure), whereas only property in physical part has a meaningful difference. That indicates the result was reflected by the character of military. The study on how veterans' perception of the old life affects the old age plan applied two contrasting factors - 'the successful perception of old age life' and 'the perception of expected matters in old age'. That represents those factors(economic, leisure) made positive effects on preparation for old age plan, but not in physical part. 'Expected perception of matters' made regulation effect, but 'success of old age perception' didn't in terms of regulation effect of learning activity as part of the veterans vocational training programs.

The housing market is transformed by a variety of socio-economic characteristics, also appeared differently according to regional characteristics. This study aims to draw out the change factors influencing on the housing market structure and to analyze the drawn factors' distribution pattern by area. For this purpose, First, targeting 251 areas in the units of city, county and districts nationwide, this study drew out demographic, socio-economic variables influencing on the housing market structure for 5 years ranging 2005 to 2010. For that, the factor analysis was conducted. Second, this study grasped the change factors of the housing market structure's spatial patterns using the kriging method, a spatial statistical method. Third, this study used the Moran I, one of spatial autocorrelation analysis methods in order to grasp whether the factors had statistically significant concentration or dispersion or showed a random distribution pattern.

This research attempts to analyze the effects of demographic factors, socioeconomic factors, health behaviors and social/familial supports on health inequalities among Korean elderly.

This study analyzed the determinants of carbon dioxide emissions through the expanded STIRPAT model using panel data from 16 metropolitan cities and provinces in Korea from 2000 to 2019. After testing cross-sectional dependence and coefficient heterogeneity of panel data, we performed analysis using MG, CCEMG, and AMG estimation methods reflected these characteristics. The results of analysis using the AMG estimation method are as follows. The coefficients of income, population, and energy intensity were statistically significant with a positive sign, but urbanization was statistically insignificant. Reduction of carbon dioxide emissions in Korea can be achieved through an increase in energy efficiency and sustainable economic growth. It is necessary to establish a policy that can contribute to sustainable economic growth by inducing productivity improvement through technology innovation reducing carbon dioxide emissions in the long-term as well as building a low-carbon society through active development of carbon dioxide reduction technology.

The purpose of the study was to examine the difference of housing welfare outcomes between public rental housing and market rental housing. Housing welfare is defined as living at adequate, affordable housing with stability and measured as substandard housing, unaffordable housing, unstable housing. This study was based on 2016 Housing Fact Finding Survey, sampled the households which their incomes are below 120% average income of city workers. This study controlled the socio-economic characters of householders to identify the difference of housing welfare performance between public and market rental housing. The study showed the ratios of public rental housing of substandard housing and unaffordable housing are not low. But It is revealed that the achievements of housing welfare of the public rental housing are better than market rental housing and the differences between them are more consistent after controlling the socio-economic characters of householders. The problems of substandard housing, unaffordable housing and unstable housing in market rental housing are more than public rental housing. This study provides the basis that the regulation for market tenant protection should be reinforced and the policy of public housing should be expanded and improved for housing welfare.
