In recent years, the state of the water quality of Han river has been among the top public concerns. This paper measures economic value of multiple environmental impacts of improved water quality of Han river using a choice experiments approach. The choice works that take into account trade-offs between price and environmental attributes for a preferred option turned out to be within respondent' ability to reveal their preferences, and the willingness to pay estimates were statistically significant. This study allows policy-makers to provide useful quantitative information that can be referred to as a benchmark for upcoming water projects.

A coastal marine ranching project in Uleungdo had been conducted for 5 years from 2013 to 2017 with investment costs of 5 billion won, for the special purpose of the deployment of artificial reefs, the release of young fishes. The paper focuses on an ex-post analysis of the economic feasibility for the project after completing the project, which is apart from a preliminary viability. For economic analysis, the economic benefits are derived from direct benefits including increasing effects of fisheries income and saving effects of harvesting costs, and indirect benefits including increasing effects of recreational fishing and preservation effects of coastal marine ecosystems while economic costs include releasing and purchasing costs of artificial reef and juvenile fish, R&D costs, maintenance costs and harvesting costs. The result shows that the project should not be accepted according to NPV=-0.125 billion won, IRR=4.5% and B/C ratio=0.98 under Scenario 1 which considers direct benefits and indirect benefits excluding the preservation values, while the project should be accepted under Scenario 2 indicating NPV=30.9 billion won, IRR=11.3% and B/C ratio=1.49 which considers the direct benefits as well as the indirect ones including the preservation values, based on 4.5% of the social rate of discount.

최근 소비자들은 쾌적한 삶의 추구와 가족 중심적 사고로 여가와 레저를 중시하고 물리적 가치보다 정보가치와 시간가치를 더욱 중요시하여 쇼핑에서도 편익성을 추구하는 경향이다. 이와 함께 국내의 소비생활 양식이 서구형으로 변화하고, 교육기회의 증가, 신용사회의 정착, 정보화 사회의 출현 등 홈쇼핑 시장의 성숙조건이 갖추어져 있어 홈쇼핑에 대한 수요는 더욱 증가할 것으로 기대된다. 이에 본 연구는 홈쇼핑으로 의류제품을 구매하는 소비자의 특성을 파악하여 홈쇼핑 활성화에 다소 도움을 주기 위하여 실시되었다. (중략)

새로운 기술과 문명의 출현에는 이로 인한 생활편익과 더불어 다양한 역기능이 수반된다. 이를테면 유전공학은 생명연장의 꿈을 실현시킬 수 있겠지만 인간의 존엄성을 훼손하는 부정적인 측면을 지니고 있다. 오늘날 정보통신기술에 의한 인터넷 역시 지식정보를 무한정 얻을 수 있으나 컴퓨터 바이러스, 사이버 범죄 등으로 피해를 당하기 쉽다. 공업화에 따른 환경오염의 전철을 교훈삼아 정보화 초기부터 다양한 역기능에 미리 대처해야 미래에 발생할 수 있는 사회적 비용을 크게 줄일 수 있다.

Korea government promote renewable energy as the core of their energy matrix to break the dependence and reduce greenhouse effects. This study analyzes the economic assessment of Solid Refuse Fuel project in urban area, considering the marginal external costs of air pollution in this area. Assessment index defined as costs (i.e., construction cost, operation cost) and benefit (margin, external cost) data which is located in Sudokwon landfill site. The result indicates that cost-benefit analysis of SRF is calculated as 1.0. In addition, SRF project is very sensitive about electric power selling price, operating cost and labor cost according to inflation rates. This study shows that the sustainability of SRF project is required the government financial support like investment funds as well as policy support. Variability analysis of SRF economic assessment due to renewable energy can be used for making policies in various fields such as waste and public energy field.

지식정보사회로의 가속화는 국가의 새로운 역할을 요구하고 있다. 이 중 가장 중요한 것이 사회변화에 앞서가는 새로운 개념의 국가 사회간접자본의 확충이 될 것이다. 사회간 접자본(SOC)은 경제, 사회, 안보 등 국가의 모든 영역에 파급효과를 미치는 국민 경제의 기반을 제공함과 동시에 모든 국민 생활과 삶의 질 제고에 필요한 바탕을 제공하며 궁극적으로 국가경쟁력의 핵심역할을 한다. 하지만, 우리나라의 사회간접자본은 그동안의 지속적인 확충에도 불구하고 선진국에 비해 사회간접자본의 경쟁력이 취약한 것이 사실이다. 따라서 기존 사회간접자본와 우리나라의 첨단 디지털인프라(ICT)의 발전적 결합을 통해 사회간접자본을 지능화.첨단화하여 교통, 물류 등 사회 각 분야의 경쟁력을 높이는 한편, 다양한 부가가지 창출의 기회와 편익을 제공하는 방안을 제안하고자 한다.

The Korean government is considering the implementation of the marine debris pollution abatement technology program (MDPATP) to mitigate the negative impacts of marine debris and systematically manage marine debris through scientific researches such as monitoring and environmental impact assessment of marine debris. In this regard, this study attempts to analyze the economic feasibility of the MDPATP in order to provide policy-maker with useful information. To this end, the indices for economic feasibility such as net present value (NPV), benefit/cost (B/C) ratio, and internal rate of return (IRR) are presented. The results show that NPV, B/C ratio, and IRR are computed to be 45.7 billion won, 2.72, and 17.12%, respectively, which are bigger than 0, 1.0, and 5.5%, and that the MDPATP passes the cost-benefit analysis. Thus, it is concluded that it is socially profitable to conduct the MDPATP.

An asymptotic distribution of the ratio of two normal vectors is estimated. Using the estimated asymptotic distribution, an approximation method to estimate confidence interval of passenger's value of travel time is proposed. As a result of empirical study the 95% confidence interval of value of travel time of home-to-work trips in city of Seoul is estimated at ￦7341.25$\pm$1945.05/hr.

This study analyzed the contents of articles on GMO in Chosun Ilbo and Hankyoreh from 1994 through 2015 to check the trend of reporting on GMO as a science and technology risk issue. As a result, 'risk' and 'anxiety/concern' were continuously treated as important subjects, and there was a lack of depth and journalist's professionalism in all three periods: 'Introduction of GMO technology (1994-2000)', 'Development of GMO technology (2001-2010)' and 'Social acceptance of GMO (2011-2015).' In a comparison between the media with different ideological goals, the Chosun Ilbo had a stronger new-technological inclination to GMO than the Hankyoreh in reporting topics and tones of arguments. As a result of checking the relation of the tones in reporting with the 'risk-benefit' of GMO, reports in negative tones underlined 'risk' while those in positive tones, 'benefit.' This study could suggest improvements of subject bias and unprofessionalism in the domestic science journalism, the barometer of public awareness of disputes over science and technology risk.

This research analyzed the characteristics of social capital and sharing economy, which are the new paradigm in the development of the entire society. In addition, it identified the social roles of a public library as a mediator that promotes the social benefit by conducting a survey questionnaire. As the results of the analysis through correlation analysis and hierarchical multiple regression analysis, social capital and sharing economy are the co-related societal phenomenon, and public libraries positively effect on the construction of social capital and the participation in sharing economy. From the perspective of the roles of a public library as a mediator between social capital and sharing economy, it was identified that various programs provided by public libraries positively effect on mediating social capital and sharing economy.
