Transport Social Overhead Capital refers to public utilities necessary for a nation's basic economic activities, and is divided into roads, railway, subway, ports and so on. It is important to be able to provide these SOC in the right place at the right time to enhance productivity and competitiveness of a nation. In this study, correlation and factor analysis on countries' socioeconomic and transport indicators were performed in order to understand the need for expansion of SOCs including railway, and to identify the impact they have on national competitiveness(productivity). As a result, GDP showed high correlativity(0.59~0.99) with factors such as population, land area, extension of available railroad, and road extension. Specifically, through the analysis of Russia's urban transport system and comparison between socioeconomic indices and SOCs of OECD countries, it was examined that how increasing transport infrastructure investments could enhance national competitiveness. In conclusion, opening new Light Rail greatly affects the growth of GDP followed by the increasing extension of available railroad. Furthermore, if available railroad extension is increased by 10 % from 2014, assuming high speed tram is opened, GDP will likely increase by 21.6%.

The concept of community capacity is regarded as the ability of people and communities to do works associated with the determinant factors and indicators of the circumstances of socio-economic, environmental and physical contexts. Building capacity of communities to effectively analyze our problematic issues and planning of community development is often required to scrutinize current status of community of socio-economic and infrastructural capacity development with GIS. We consider community development as a planned effort to build assets that increase the capacity of communities. Spatial asset mapping is the process enabling to identify and make inventories of tangible and intangible assets. This mapping requires developing a capacity inventory that collects individual organizational and community capacities in view of human, socio-cultural, natural, financial, digital, and physical capacity. The purpose of this research is not only designed to suggest a new concept capacity building, but also proposes a more creative framework of asset-based community cap linking to parcel-based spatial asset mapping and capacity mapping process.

This research empirically analyzes, from an ecological perspective, whether socio-economic factors of the regions in which the elderly live have any actual influence on thoughts of suicide on the part of the elderly. Microscopic data either included outliers in part of the variables, including income and other variables of that type, from among source data from investigations into actual conditions of the elderly in 2014. Regarding macroscopic data, the indices that represent social and economic situations in each region, which were provided by KOSIS, were selected. Regarding the method of analysis, hierarchical or multi-level analysis models were applied by considering special hierarchical characteristics and heterogeneity at the personal and regional levels. The analyses showed that the following had statistically significant influences: 1. the cost-of-living index and the national basic supply and demand rate of the region; 2. the extent of natural disaster damage; and 3. the number of leisure and welfare facilities for the elderly, compared to the elderly population. Based on the results, proposals are made for systematic and practical endeavors in the community.

Marine oil spill accidents are occurring continuously due to the marine transportation of the oil. While building a preventive system for oil spill is uttermost necessary, we also need to have a systematic response system to handle the oil spills that inevitably occur. So far, studies have focused on the environmentally sensitive resources affected by oil spills. However, there is a need to conduct research to evaluate the damage to the socially and economically sensitive resources that make up the life of local residents. This study represents the process of building an analytical framework for the assessment of socioeconomic resources affected by marine oil spills. While it is important to provide a scheme for identification and indexation of socially and economically sensitive resources that is compatible with Korea's situations, using existing data for identifying socio-economically sensitive resources might also be meaningful. However, to allow accurate analysis for better evaluation, we need to select more applicable data among the various indicators. In this research, we have reviewed many existing case studies of sensitive resources, studies of the variables that have been used for indexing sensitive resources, and various factors considered in SIA (Social Impact Assessment). Based on the findings, we classify socio-economically sensitive resources into marine products acquisition, population, land usage, administrative area, and cultural heritage and tourist region.

Social changes due to ICT like Big Data, IoT, Cloud and Mobile is progressing rapidly. Now, we get out of the old-fashioned frame was measured at the level of the information society through the introduction of PC, Internet speed and Internet subscribers etc and there is a need for a new type of diagnostic information society framework. This study is the study for the framework established to diagnose and measure post-information society. The framework and indicators were chosen in accordance with the technological society coevolution theory and information society-related indicators presented from authoritative international organizations. Empirical results utilizing the indicators and framework developed in this study were as follows: First, the three sectors, six clusters (items), 25 nodes (indicators) that make up the information society showed that all strongly connected. Second, it was diagnosed as information society development (50.34%), technology-based expansion (25.03%) and ICT effect (24.63%) through a network analysis (ANP) for the measurement of importance of the information society. Third, the result of calculating the relative importance of the cluster and nodes showed us (1)social development potential (26.04%), (2)competitiveness (15.9%), (3)ICT literacy (15.5%) (4) (social)capital (24.3 %), (5)ICT acceptance(9.54%), (6)quality of life(8.7%). Consequently, We should take into account the effect of the economy and quality of life beyond ICT infrastructure-centric when we measure the post-information society. By applying the weighting we should performs a comparison between countries and we should diagnose the level of Korea and provide policy implications for the preparation of post-information society.

A currency exchange is the rate to exchange currencies between different countries and the one of important factors to measure the economic size or status of a country. The currency exchange is affected by various economic or social events and changed dynamically. However, since too many economic and social factors affect the exchange rate and the leverage rate of each factor is so floating, it is difficult to define clearly the relationships between the exchange rate and the specific factor. In this paper, we analyze the data pattern for the exchange rate and news articles. To do this, we counts the frequencies of words presented in the news articles during specific periods and compare the frequencies with the margins of exchange rates.

Over the past four decades reproductive behavior has changed slowly in much of the African countries. The average total fertility rate has fallen from six or more to near five today. Between 1960 and 2000 the largest fertility decline occurred in such Northern African countries as Algeria, Libya, and Morocco. The mortality rate has decreased in most African countries. The purpose of this study is to review the pattern of demographic transition in African countries. At first, this study focuses on the fertility transition. In Africa, the total fertility rate has decreased from 6.59 to 4.85 between 1960 and 2000. The mortality rate has also decreased in most of African countries. It is also interesting to find that there is a clear difference among African countries. In terms of infant mortality rate, Libya shows the lowest rate(17), while Mali and Somalia remain still high rate(142 and 133, respectively). This study tests a path model in which infant mortality rate acts as an intermediate variable between three socioeconomic variables and the fertility rate. The findings of this paper substantiate some of our hypotheses on the interrelationships among socioeconomic variables, infant mortality rate, and fertility rate. The result also shows the indirect effects of socioeconomic variables on fertility rate via infant mortality.

이 연구는 2003년에 실시된 한국종합사회조사(KGSS)의 가족모듈과 국제사회조사기구(ISSP)의 2002년 가족모듈을 이용해 한국의 가족가치를 국제적인 수준에서 비교 분석하고 있다. 한국에서는 최근 여러 가치와 태도가 급변하고 있다고 믿어지고 있다. 그 결과 세대간의 가치 및 태도의 차이가 크고, 이는 사회내 세대간 갈등의 뿌리라고도 이해되고 있다. 그러나 이에 대한 과학적인 검증은 많지 않다. 이 연구는 이런 시점에서 한국의 여러 가지 중 가족가치의 영역에서 세대간 가치가 크게 나타나고 있는지, 국제적인 수준에서 보면 우리나라의 세대간 가족가치 차이가 크다고 볼 수 있는지를 kurtosis라는 지표를 통해 분석하고 있다. 결혼, 동거, 이혼 및 부부의 성역할에 관한 가치 및 태도를 분석해 본 결과 한국인의 가족가치는 가톨릭이 지배적인 필리핀의 가족가치와 비슷할 정도로 매우 보수적이고 전통적인 것으로 나타났다. 일반적으로 가치관의 변화는 경제발전 정도에 크게 영향을 받는 것으로 알려져 있다. 그런데 한국은 한국보다 경제발전 정도가 크게 뒤져 있으면서 보수적인 가족가치관이 지배적인 필리핀과 가족가치의 수준이 비슷하게 나타나고 있다. 세대간 갈등의 원인이라고 볼 수 있을 정도로 가족가치의 세대간 차이가 큰지 kurtosis를 이용해 분석해 본 결과, 한국보다 오히려 일본의 세대간 가치관의 차이가 더 큰 것으로 나타났다. 한국에 세대간 가치관의 차이가 있지만, 외국과 비교해보면 한국의 세대간 가치관 차이가 더 두드러진다고는 보기 힘들다.
