우리의 생활 주변에는 자연적으로 배출되는 오염물질과 인간의 사회활동을 통해서 발생하는 인위적인 오염물질이 있다. 배출원에서 발생하는 오염물질은 배출조건이나 주변지역의 장애물, 또는 기상조건 등과 같은 많은 변수들 때문에 오염물질의 확산에 많은 영향을 받는다. 따라서 실제 대기 중의 복잡한 확산특성을 이해하기 위해서는 바람특성에 대한 보다 정확한 정보가 필요하다. 이러한 확산조건을 정확히 파악하기 위해서는 현장에서 장기간의 시간을 가지고 실측 데이터를 얻는 것이 가장 좋으나 이는 경제적 또는 실험적인 한계로 인해 불가능하다.

With a substantial rise in divorce rates since the mid 1990s, single-parent households are increasing rapidly in Korea. Often it is believed that children in single-mother households suffer the most economically and socially with the marital disruption of the parents. This study hypothesizes that in Korea the socioeconomic status of single-father households may be lower than that of single-mother households mainly because low-income divorced women are not able to form their own households with children. The analysis is based on two sub-samples from the 2% sample of the 2005 Census, one, with children 12 years old or younger and, the other, with divorced mothers of children of the same ages. The findings support the hypothesis that previously-married single fathers show the lowest educational and occupational status among 6 groups of parents: fathers and mothers from two-parent families, fathers and mothers from married but spouse-absent families, and previously-married single fathers and mothers. Divorced mothers'likelihood of living apart from their children has a strong negative association with their educational attainment, with the highest likelihood among women of middle school or lower education and the lowest likelihood among women with college education. Although single mothers comprise a larger percentage of single-parent households, single-father households demonstrate a particular vulnerability with their weak socioeconomic status.

This paper aims to explore the institutional traits of the federal employees pension system in the United States and the direction of its reform. Currently the United States has two systems of the federal employees pension. One is CSRS, the other is FERS. The former was firstly introduced in 1920 as a generous DB pension well before the establishment of the Social Security System(OASDI). What led to the latter, FERS was the Social Security Amendment Act of 1983 and Federal Employee Retirement System Act of 1986. The crucial difference between the CSRS and the FERS is the contrasting characteristic of their relationships with OASDI. The CSRS has just one source of retirement benefit(DB pension) without OASDI benefit, whereas the FERS has three sources(OASDI benefit, basic annuity(DB), DC typed TSP benefit). When it comes to FERS, what matters most is TSP(Thrift Savings Plan).

In a research model, social environmental factors are barely considered. Heterogeneity and a few studies showed identities and varieties of generation. Based on these results, several suggestions are presented; First, consideration about the concepts of successful aging On a broad range is required. Secondly, concepts and influence factors should be clearly identified.

Characteristic of participants in the self-support program has an intrinsic attribute that has not changed strongly depending on time, as age, sex, and education. By investigating the characteristic of participants in the self-support program related to the self-support outcome, it becomes possible to both set up target groups and give effective self-support programs. This research analyzed the effect of the characteristics of participants in the self-support program to the self-support outcome by General Linear Models(GLM). The results showed that education, self-support program type, region, poverty, age, child protection, sex variables affected self-support outcome by main effects and interaction effects. There was different in pattern of self-support outcome depending on characteristics variables of participants, so it is necessary to make the self-support program in detail fit into characteristics of participants.

The purpose of this study is to analyze the characteristics and performance of the High Line as an example of Industrial Heritage Regeneration, and to derive implications for setting the direction of urban regeneration. The results of this study are summarized as follows. First, five measurement elements were derived from governance, physical performance, economic performance, social performance and cultural performance as an analytical framework for analyzing the characteristics and performance of the high line as a case of industrial heritage regeneration, and a total of 15 indicators were selected for each element. Second, the analysis of the characteristics and performance of the High Line regeneration shows that the High Line regeneration project has resulted in the establishment of effective governance, the physical improvement considering historicity and placeness, and the economic revitalization of the underdeveloped mid-western region of Manhattan, while the drive-out of natives due to gentrification.

This research was conducted with goals to reducing arson and finding its relationship with social phenomenons. Especially, unlike previous researches, focus has been on the economic indicators, and the effect of economic indicators on arson. As a result, we were able to find the relationship between economic indicators and arson. When growth rate and consumer index prices decrease, the economy stagnates and thus incidents of arson increases. In contrast, when growth rate increases and consumer index prices increase, the rate in which arson occurred decreased. Also, we have found that when personal debt rate increases, the numbers of arson incidents increased as well.

This study was conducted to derive a model of a sustainable economic system for humanity in the era of service economy that requires a paradigm shift. A new long-term sustainable development model has been built on the basis of thousands of years of economic operation experience. Currently, the world is operating the capitalism as the main economic system because there is no better alternative, and the changing economic and social environment such as the advent of the 4th Industrial Revolution is exacerbating the problems of the capitalism, such as job shortages and inequality. In this study, we analyzed the economic management system experienced by human society, and derived an economic system model that is ideal for the modern and future society and is sustainable in the long term. The conditions for a long-term sustainable economic system were presented first. It must be a model that can solve the problems of the current economic system. It must be a model that is faithful to the characteristics of the modern economic society and the nature of the economy itself. And since the new economic system is for humanity, it must be based on the common principles of human society. It should be a model that continuously guarantees core values such as equality and freedom required by human society. After analyzing the problems of the current economic system and analyzing the conditions required for the new system, the basic axioms that the new economic system should be based on were presented, and a desirable model was derived based on this. The structure of the derived model and the specific operation model were presented. In the future, research is needed to specify the operational model so that this model can be settled well in different environments for each country.
