In this study, the structure and role of governance system, which can be adapted as a effective way to negotiate the water resources related conflicts, was presented and the features and a characteristics of the various types of citizen participation model was analyzed. Also, the scientific approach based on Shared vision model, Game theory and Institutional design theory was introduced and applied to current conflict issues in Korea. The governance system with engineering negotiation model, which is presented in this study, can be used effectively in the field of water resources related conflicts to provide the scientific alternatives by participation of water related stakeholders.

This paper performed an experimental study to test the validity of the prospect theory proposed by Tversky and Kahneman as an alternative to the expected utility theory. 115 college students attended the hypothetical games to choose one of two lotteries, one is safe option while the other one is risky. The risky options were set up to have low, medium or high probability of payoffs or losses. The amount of payoffs and losses of the lotteries was either large or small. Maximum likelihood estimation of the hypothetical games have shown that in case of high probability of positive payoffs the respondents were risk averse and when the probability of positive payoffs were small the respondents were risk loving. when the possibility of loss is high they were risk loving, while the probability is of loss is low the respondents were found to be risk averse. When the probability of risky options were medium the results were significant statistically in case of only losses. The amount of positive payoff or losses does not affect the results. Overall the results of this experiments support the prospect theory more than those of Laury & Holts (2008).

Bridge is an indispensable facility as a social overhead capital. This study suggests and examines the ways of Economic valuation on maintenance alternatives for Bridge. In order to evaluate each alterative on the basis of the same time, the concepts of the basic year and the valuation year are introduced and applied. Interest rates and discount rates are also applied according to the time when each cost is incurred. This study also suggests the ways that the objects of the valuation on maintenance alternatives are not limited to construction cost, but the valuation period is fixed and so maintenance cost and remaining value incurred by maintenance alternatives are valuated. Furthermore, this study shows the way to estimate and evaluate maintenance cost through direct construction cost and annuity present value coefficient and the way to estimate remaining value based on the basic year. In addition, this study suggests economic valuation system, cost methods and analyses of the result through verification. The proposed system is considered to be applied to practical business.

The Korean government establishes a strategy to develop the Busan New Port as a world ranking two transit-oriented port. This paper aims at presenting an efficient inter-terminal transport (ITT) system in the Busan New Port as a method of achieving the government strategy. First, it presents results of long term forecast for the inter-terminal transportation volume in the port. Second, it proposes two systems to treat ITT in the port; Double stack Multiple Trailer System (DMTS) and Rail-based transportation system. The implementation methods in the port are introduced in detail for the both systems, and the required number of the systems and costs are calculated for implementation of both the systems. B/C for DMTS is analyzed to 3.7, moreover unit-fare per [$ton{\cdot}km$] can is lowered to 67% against current fare. DMTS is shown to highly potential for efficient ITT in the port.

Container terminals in Gwangyang Port are facing in domestically and internationally a lot of changes including opening of Busan New Port and China ports. Compared to new ports, container terminals in Gwangyang Port possess old equipment and facilities. Therefore, in order for Gwangyang Port to maintain its service level and remain competitive, it needs to undergo remodeling to enhance productivity economically. Remodeling activities should be implemented on a continual basis by developing and applying new technologies such as those for gate system, yard system, berth system. In order to review the alternative, we performed questionnaire survey and expert interview. From the results of analysis, we suggested remodeling technology alternatives, priority of remodeling and improvement effect by remodeling introduction stage.

본 논문은 영국과 미국을 중심으로 실업 연구 동향을 고찰함으로써 우리 날 실업연구를 수행하는데 있어서의 과제와 이론적 기초를 모색하는 것을 목적으로 하였다. 실업의 지리적 패턴에 대한 관심은 계량혁명 시기에 시작되었으며, 이후 실업에 대한 지리학적 연구에는 많은 변화가 있었다. 실업에 대한 공식 정의들을 실업에 대한 제한적 묘사만을 제공하기 때문에 대안적인 지표-보다 광범위하고 포괄적인-가 요구되고 있다. 공식정의에 근거한 지역실업 연구는 현실의 문제를 축소하게 되는 경향이 있는데 이러한 문제를 해결하기 위해서 노동시장 계정 접근이 대안적인 연구틀로서 제시된다.

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.

우리는 어떠한 문제이든지 인간들이 구성하고 있는 모든 조직 및 정책전략에 있어서 크고 작은 의사결정들에 의해서 움직여진다고 할 수 있다. 불확실한 상황에서의 의사결정이 필요한 경우는 무수히 많지만, 분야별로 분류해서 의사결정을 지원한다 해도 정확한 결과를 예측하고 시행할 수 있는 표준안은 완벽하게 준비되 있다고 말할 수 없다. 단지 완벽에 가까운 의사결정방법론을 제시하고, 의사결정을 할 뿐이다. 본 연구논문에서는 정보기술 관련 벤처 사업의 전략적 대안들을 어떻게 하면 가장 최적으로 추출하고, 분석해서 그 대안들을 위해 어떻게 준비할 것인가에 대한 지원프로세스를 중요 관점으로 해서 불확실한 상황에서의 직면한 문제에 대한 해결책을 제시하고자 한다.

기자들이 쓴 "신한국군 리포트"에는 한국군 장군들의 모습이 여과없이 적나라하게 묘사돼 있어 마치 현장을 보는 것과 같은 느낌이 들게 한다. 국방연구원에서 재직한 학자들의 저술인 "선진국방의 지평"에는 입문서 성격의 책으로 구체적인 대안제시가 아쉽다.

등록금 인상 문제를 둘러싼 갈등이 지속되고 있는 올해 각 정당과 교육단체들은 등록금 인상에 대한 정책적 대안을 제시하고 있다. 반복되는 등록금 인상의 악순환을 근절시키기 위해서는 보다 구체적이고 현실적인 대안이 요구된다. 우선 우리 정부와 국회에서 등록금 인상 억제방안의 입법화를 추진할 수 있어야 한다. 이와 함께 정부차원에서 교육예산 확보를 위한 구체적 방안을 수립해야 한다. 그리고 사학의 예·결산을 산출근거까지 상세히 공개하여 학교당국과 학생들 간에 상호 신뢰감을 든든히 해야 한다.
