PURPOSES : The aim of this study is to analyze economic effect of bike-sharing after its introduction in Korea. METHODS : This study reviews current bike-sharing situations in Korea and other nations. We conduct surveys on bike-sharing system's bike usage patterns and economic benefits in Changwon and Goyang cities where public bikes are the most popular in the nation. Economic benefits are itemized after reviewing relevant previous studies. Then, the survey is implemented using the Contingent Valuation Method (CVM). Then estimated benefit is compared to the cost which is necessary for bike-sharing introduction and operation. RESULTS : Using the average WTP per household, the total economic benefit of bike-sharing is estimated as much as 1.75 billion KRW to 3.75 billion KRW in Goyang and Changwon city. Using estimated benefit, economic effect of bike-sharing are calculated as 0.69 and 1.00, respectively. CONCLUSIONS : The result of this study shows bike-sharing could be useful economic policy in Korea. However, economic effect of bike-sharing differs by city.

The specific purpose of this study is to develop the numerical guide for the cost-benefit analysis of ORE ($/person-Sv reduction) to meet the criterion of ALARA in the design stage of the KNGR. In deriving the guide, the risk factor which is defined by the risk to unit collective radiation exposure dose (deaths/person-Sv) and the monetary value of human life ($/death) are required. The risk factor has been estimated from various clinical data accumulated for a number of years and continuously modified. And the monetary value of human life is usually quantified using the human capital approach. In this study, the risk to radiation exposure perceived by a group of people is investigated through an extensive poll survey conducted among university students in order to modify the existing risk factor for radiation exposure. And in evaluating the monetary value of human life, the QOL factor is introduced in order to incorporate the degree of public welfare or quality of life. As a result of study, a value within the range of 151, 000~172, 000 dollars per person-Sv reduction is recommended as the appropriate interim numerical guide for cost-benefit analysis of ORE to meet the criterion of ALARA in the design stage of the KNGR. A poll survey was also conducted in order to see whether the public acceptance cost of nuclear power should be incorporated in developing the guide, and the result of study shooed that such a cost does not need to be considered.

Catastrophic health expenditure refers to when a household spends more than 40 percent of disposable income for out-of-pocket-expenses for healthcare. This study investigates the percentage of South Korean household which experienced the catastrophic health expenditure between 2006 and 2016 with the National Survey of Tax and Benefit and the Household Income and Expenditure Survey data. Percentage of households with the catastrophic health expenditure and tread tests were conducted with weight variable. The results of the National Survey of Tax and Benefit and the Household Income and Expenditure Survey showed 2.17% and 2.92% of households experienced the catastrophic health expenditure in 2016. In trend analysis, the National Survey of Tax and Benefit showed a statistically significant decreasing trend in the proportion of households with the catastrophic health expenditure (annual percentage change [APC]=-4.03, p<0.0001). However, the Household Income and Expenditure Survey revealed a statistically significant increasing trend (APC=1.43, p<0.0001). In conclusion, this study suggests that optimal healthcare alternatives are needed for the catastrophic health expenditure and monitoring low-income households.

최근 도시정보시스템(urban information system, UIS)이 구축되고 실질적인 활용도가 높아 감에 따라 UIS는 지자체 정보화의 핵심수단으로서 보편화되어 가고 있다. 그러나 지하매설물관리를 중심으로 도시정보화가 추진되고 행정조직 내부수요만을 중심으로 운영해 갈 경우 UIS의 비용편익구조는 취약해질 수 있다. 이 연구에서는 국가 GIS팀이 도시정보화의 시범도시로 선정한 청주시의 UIS를 대상으로 비용과 편익을 분석하였다. 청주시 UIS의 경우, 초기에는 도시계획종합정보시스템을 구축하여 비용부담이 그리 크지 않았다. 1993년 GIS의 구축을 시작하여 2002년에는 UIS의 완성을 이루기까지 10년 만에 플러스 순편익을 발생하여 비교적 건전한 비용편익구조를 갖는 효율적인 UIS모델이었다. 그러나 1998년부터 중앙정부의 재정지원으로 지하시설물 수치지도화 사업을 추가하면서 UIS의 비용편익구조가 취약해져 2015년에야 긍정적인 순편익이 발생하는 것으로 나타났다. 이에 대하여 이 연구는 비용편익비율의 분석, 할인율 모바일 GIS 등을 적용한 민감성 분석을 실시하고 있다.

To decide a reasonable investment priority of public enterprises, it is required to have an efficient evaluation standard. However, without having a standard, a budget for those enterprises has been allocated. In this research, for the efficient and reasonable budget allocation, it is discussed how to decide investment priority of information and communication enterprises of the government. In order to examine possible alternatives of the investment priority of information and communication enterprises of the government, seventeen enterprises were chosen from the enterprises of Ministry of Information and Communication. Public benefit, economic benefit, technology, politics, and step-up increase of budget were set up as evaluation standards and 16 specific standards were set up as subordinates. A hierarchical decision model was designed and analyzed by using AHP.

Understanding public perception on nuclear research reactor is necessary for the policy maker to adopt such technology in Thailand, especially the locals who live in the proposed location. The study compared perceptions between the locals living near the proposed nuclear research reactor location (within 5 km) and those living in the outer region (5-15 km). Structural equation modeling technique was adopted by assuming casual relationships between latent variables including social status, information perception, trust, benefit perception and risk perception on the local acceptance of research reactor. The results showed that the strongest relationships for both the inner and the outer perimeters were from information perception toward technology acceptance via trust and benefit perception. While both zones showed similar results, the outer perimeter seemed to show slightly stronger effects than those in the inner perimeter.

일반적으로 공공임대주택은 자원의 배분뿐만 아니라 복지의 분배에도 영향을 미친다. 본 연구에서는 우리나라의 공공임대주택에 대한 제도적 변화와 공공임대주택의 편익에 대해 설명해 보고자 한다. 기존의 많은 연구들은 동조적 선호체계를 고려하여 공공임대주택의 편익을 분석함으로써 공공임대주택에 따른 소득효과에 대해 명시적으로 고려하지 않았다. 이에 반해 본 연구는 비동조적 선호체계를 고려함으로써 공공임대주택에 따른 소득효과를 명시적으로 고려하였다. 이러한 선호체계를 바탕으로 시행한 분석 결과, 공공임대주택의 편익-비용 비율은 0.91을 기록하였으며, 이는 우리나라의 공공임대주택에 따른 사중손실(deadweight loss) 규모가 크지 않음을 반영한다고 볼 수 있다. 그러나 편익의 분포를 살펴보면 편익과 소득수준 간의 상관관계가 그리 높지 않아 공공임대주택의 궁극적인 목표계층인 저소득층에 대한 실질적인 혜택이 그리 크지 않은 것으로 나타났다.

본 논문에서는 슈퍼컴퓨터 공동 활용의 효과에 대한 경제성 분석을 비용편익분석 방법을 통해 수행한다. 슈퍼컴퓨터를 활용함에 있어 국가센터 등에서 중앙 집중형 범용 시스템을 운영 및 서비스하는 체제와 개별 기관들이 자체적으로 구축 운영하는데 소요되는 비용을 추정하여 비교한다. 공동 활용의 경우 기존 슈퍼컴퓨터 도입 및 운영 실적에 근거하여 비용을 쉽게 추정할 수 있다. 그러나 개별 사용에 소요되는 비용은 실제로 운영하고 있지 않은 관계로 슈퍼컴퓨터의 성능 및 기반시설, 인적 요인 등에 의한 변동성을 고려한다면 그 추정이 매우 어려운 실정이다. 따라서 본 논문에서는 개별 사용 비용을 산출하는 객관적이고 타당한 방법을 제시하고 두 대안의 비용을 비교하여 공용 슈퍼컴퓨터 운영 서비스가 경제적 측면에서 얼마나 효과적인지를 분석한다. 분석결과에 따르면 공용 슈퍼컴퓨터의 활용이 개별 사용에 비해 운영비용 측면에서 연평균 약 103억원, 6년간 총 620억원이 절감된다. 따라서 공용 슈퍼컴퓨터의 활용은 개별 도입에 비해 상당한 규모의 경제적 효과를 가져 올 것으로 판단된다.

Public diplomacy activities can benefit from social capital theory, when its social dynamics is elucidated in the investment of complex social networks and in the establishment and management of relationships with foreign publics. Social capital theory explains that actors can produce purposive actions to mobilize resources in social structures, which thus explains the dynamics of social interactions. In response to the lack of conceptual frameworks for understanding public diplomacy activities within social capital theory, we conducted a narrative literature review that intends to identify the means through which international actors, such as governments, engage with foreign publics through the dynamics of social networks and the resources embedded in them. In addition, we explored the multidimensional characteristics of social capital to enhance the comprehension of the manner in which actors access, share, and maintain resources in target communities, institutions, or organizations through public diplomacy activities. In summary, we highlight the importance of new theoretical explorations on the application of social capital theory to public diplomacy and the need for a research agenda in the field.
