To enhance the competition of National power, the investment of SOC is an essential factor for infrastructure construction. The capital for SOC is so gigantic and the national finance is limited, engagement of various subject is necessary. So, Government is promoting the private sector to invest capital in SOC development. Nevertheless the increasement of SOC investment, various problems were issued in selection & operation of BTL. Therefore, to raise the probability of success for BTL project, escalation, unification and specialization of BTL affairs, BTL selection process were suggested in this study.

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%.

1970년대 중후반 경제개발 5개년계획의 시작과 함께 시멘트산업은 다시 도약기를 맞게 된다. 정부의 지속적인 공업화 정책에 따라 사회간접자본의 확충을 위한 도로, 항만, 댐 건설 등에 주력하면서 시멘트 수요가 크게 늘어났다. 특히 1968년 경부 고속도로의 착공 이후 공장신설과 신규 주택건설 등 각 부분에서 수요가 급속도로 늘어나 시멘트 생산시설의 확충도 급진전됐다. 이렇듯 1970년대에는 우리나라가 여러 어려운 여건 하에서도 도전을 통해 시련을 극복하고 마침내 획기적인 국력신장을 성취한 도약의 시기였다. 특히 1970년대를 거치며 이룩한 우리나라의 괄목할만한 성장은 세계를 놀라게 하는 것이었다.

우리나라는 과거 10여년 동안의 급속한 경제 성장과 이에 따른 국민 생활 소득향상의 결과로 자동차 보유 대수가 연평균 22%씩 증가하여 1997년 7월 현재 1000만대를 넘었으며 자동차 교통의 대중화 시대로 접어들게 되었지만, 사회 간접 자본인 도로 교통 안전 시설에 대한 투자등이 상대적으로 저조하고 운전자의 부주의 및 음주운전 등으로 인하여 교통 안전 사고가 점점 증가되고 있다. (중략)

In this research we estimated regional gross fixed capital stock of transport sector, such as road railroad, airport and seaport during 1968-1997 in Korea. We also compared our estimation results with those of Korea and Japan. As basic analytic method, we used the regional allocation method. To estimate regional gross fixed capital stock of transport sector, we used the basic data on national wealth surveys in 1997, regional land price index and regional facilities index in transport sectors. We used the most reasonable data in the process of estimation after reviewing the collected data In order to get the reasonable capital stock by regions. we chose the allocation index which can minimize the difference between the estimated result and the real regional capital stock in the process to allocate the total gross capital into the regions. Compared our results with those of other researches in Korea, estimates in our research project could be said more accurate than those.

This study aims to examine the relationship between physical environment and depression symptoms of middle-aged and older adults in metro city. To verify correlates of community environment and depression, mediating effect model structured by social capital and sense of coherence(SOC) were used. For the purpose, a survey was conducted aged 48 - 70 from the local community centers and senior welfare centers in Seoul, and the total collected cases were 331. After data cleaning, total 309 cases were used. The structured equation modeling applied to analyse the direct and indirect effects. The findings were followed : First, the community environment did not directly affect level of depression. Second, in the indirect effect analysis, social capital was not statistically significant, thus indirect effect was confirmed only through the SOC. To be specific, the higher the satisfaction of the physical environment increased SOC, and decreased the level of depression. The results of this study shed lights on practical interventions to promote mental health of the middle-aged and older adults those who are exposed to poor community environment.

Busan Port which is the representative social overhead capital facilities for international trade of goods has need the driving force for economic development in Korea. Therefore, the central government should play the major role in building a rear road to Busan Port in order that it may function as a moor port of Northeastern Asia through the systemization of mutual assistance among connected facilities, completely equipped with port-related facilities befitting to the principal port of imports and exports. In this study, the validity of container tax is being examined, analyzing container tax which is considered as an obstacle to the development of Busan Port and its purpose, and grasping the present conditions by the realistic speculation on container tax issues and its abolition. First, the port rear road as a social overhead capital facilities, which connects port and expressway, should be considered as part of port, and port is social overhead capital invested by government. Second, the Busan City imposes taxes on container. As a result, a shipper and a shipping company are paying a double charge by paying container tax with port dues. Third, Empty container and Tranship container are the factor of Busan city traffic jam but their was excluded from container tax. This is deviate from equilibrium of the tax object. Forth, it has bad influence upon the competitiveness of Busan Port as Northeastern logistics base, as other ports who are competing with Busan Port like china, Taiwan, Japan's port make their competitiveness strong by decreasing the cost of port dues.

수자원 및 수도 시설과 같은 사회간접자본은 경제개발 초기 단계에 있어 매우 중요한 역할을 수행하여 왔다. 우리나라의 경제성장 과정에서 수자원 개발은 "한강의 기적"으로 불리며 한국 경제발전의 중요한 원동력 가운데 하나로 알려져 있다. 본 연구에서는 수자원개발의 경제적 효과를 정량적으로 분석하기 위하여 거시경제모형을 구축하고 실증분석하고자 한다. 이를 위해 1977-2014년 동안의 수자원 부문에 대한 자본 스톡을 추정하고 이를 바탕으로 경제성장과의 인과관계를 검정한다. 추정결과, 수자원 투자는 경제성장(GDP)으로의 단방향의 인과성이 존재함을 확인(1%유의 수준)하였다. 외생적 충격으로 수자원 투자가 감소하는 경우 국내 소득(GDP)에 부정적 영향을 미칠 수 있음을 시사하고 있다. 우리나라의 성공적인 수자원 개발과 경제 발전 경험은 많은 개도국에게 시사점을 제공할 것이다.

The government introduced private infrastructure projects in order to reduce its financial burden by introducing private sectors efficiency and creativity and by utilizing their funds. Through revision, the act on the private investment of the infrastructure, many changes were made in the private investment system. The evaluation task to assess the project proposer's capability and to select a promoter is regarded as the most important process for fairness and transparency of the project. In this study, the improvement of project plan evaluation task of current private infrastructure projects is proposed based on the standard guideline for evaluation procedure of private infrastructure projects provided by Korea Development Institute. In addition, software program for evaluation procedure is made to improve the efficiency and enableconvenient evaluation task.
