A disposal scheme involves not only the process of resettlement process, before and on the way of the residential environment improving program, but also the change of psychological opinion concerning to the private interest for the relocation during the projects. Major findings of the study can be summed up as follows : first, as to the resettlement burden of prior residents was imposed to low-income households, while the lowest burden was imposed to middle-income households : second, the residents were rather satisfied with the project in the early stage of the process, but later they do not want to relocate to the place where they left in the process of resettlement program.

본 논문에서는 지방자치단체에서 역점적으로 추진하는 행사나 신도시, 또는 중점 관광지 등을 홍보하는 수단으로써 3D게임을 제안한다. 현대의 도시는 잘 정비된 도로들, 고층건물들, 자연환경과의 조화를 이루는 친환경적인 요소들을 부각시키는 방법으로 정비되고 있으며 지자체들은 이렇게 변화된 도시의 모습을 홍보하는데 많은 노력과 경비를 들이고 있다. 변화된 도시의 모습을 가상현실로 구현하고 거기에 더하여 게임 기능까지 가진 콘텐츠가 지자체의 웹사이트를 통해 구현된다면 지자체의 행정에 관심이 없던 청소년들까지고 웹 사이트를 자주 방문하면서 자신이 속한 지자체에 대한 관심과 애정을 가질 수 있을 것으로 생각된다. 이런 시뮬레이션의 방법에 3D 게임 엔진의 응용은 매우 유용한 수단이 될 수 있을 것이다. 컴퓨터 하드웨어 사양의 발전으로 근래에 출시되는 3D게임은 거의 실제와 같은 배경을 구현하는데 문제가 없다. 문제점으로 지적되는 높은 게임 개발비의 부담과 거의 1-2년이 걸리는 개발 기간은 기존에 개발된 게임엔진의 활용과 게임 내 광고를 활용하여 상당부분 해결할 수 있는 것으로 사료된다. 연구의 구체화를 위해 전라남도에서 중점적으로 추진하는 프로젝트인 '서남해안관광레저도시' 사업과 '2010 전남 F1 그랑프리'를 연구의 대상으로 삼았다.

This study is to investigate the effect of environmental mitigation in relation to the construction of quay structures for containers and to estimate economic values of environment-friendly structures using CVM. The result shows that the B/C ratio of environment-friendly quay structures designed to mitigate environmental impact is 4. That is, environmental improvement work proves to generate environmental benefit over 4 times as much as the construction cost. Considering the results of the study, environmental improvement work is of great benefit to citizens, and CVM is expected to become an efficient method to measure a proper size for a large construction project as well as to forge public consensus.

The facility modernization policy has been established to improve fruits quality and to increase fruits yield per acreage. The fruit production quantity of farms joined in the policy was increased. Therefore, many fruit farms want to participate in the policy. The government has subsidized fruit farms to modernize their facilities such as rain proof, drainage way, frost proof, etc. This study analyzes the performance of the facility modernization policy focused on apple, eastern pear, and grape cultivation sector. One hundred apple farms, one hundred eastern pear farms, and 91 grape farms were surveyed. The performance of the policy was reviewed using analytical technique such as Covariate Matching and Propensity Score Matching and several policy implications were suggested.

This study analyzed the factors affecting the ruling of litigation on the housing reconstruction and housing redevelopment project based on the cross analysis and logistic regression analysis. According to cross analysis result, the defensive process prerequisite group was showed significant in many variables which were past legal relation, no ownership or association member status, double lawsuit, abuse of lawsuit right·litigation trust, existence of claim-preclusion, no standing to sue·no standing to be sued, lapse of litigation period, no legal interest, no own defect of approval. On the other hand, the offensive cause of action group was found to have no significant variable. According to logistic regression result, the defensive process prerequisite group was showed significant in many variables which were past legal relation, no standing to sue·no standing to be sued, no ownership or association member status, double lawsuit, no own defect of approval, abuse of lawsuit right·litigation trust, existence of claim-preclusion. Meanwhile, the offensive cause of action group was showed significant in only one variable that was defect in relation with articles of association. Overall, it is noteworthy that the offensive cause group showed very low significant results compared with the defensive process prerequisite group.

The present study aims to investigate the long-term channel morphological changes derived from channelization, embankment and levee construction works in unregulated fluvial channel of the Jiseock River. Analyses of aerial photographs taken past (Year 1966) and recent (Year 2002) showed the temporally remarkable changes in channel planform such as channel shape, bar migration, vegetation encroachment in bar. During the period, the natural single threading changed into braided types together with decreasing sinuosity by 9.2%, increasing vegetation occupied bar ranged 97% of total bars area. Because such channel morphological changes are closely similar to those in dam downstream channels, we assume that both/either flow regime alteration and/or sediment transport discontinuity may be critical for the fixed channel and spread of vegetated bars even in unregulated river without dam reservoir upstream. We found more reduced frequency and magnitude of flooding water level comparing with past, but no significant alteration of inter annual water level variation. Bed material has been coarsened by 4~5 times and the riverbed has been degraded in overall channel but aggraded locally in conjunction reach of tributaries. The results indicates that reduced sediment dynamics in fluvial channel which derived by bed material coarsening, river bed degradation and unbalanced sediment transport capacity between tributary and mainstem can be a causal factor to trigger channel morphological changes even in unregulated rivers.

This study targets to recognize needs of adopting public management system in Urban Renewal Project. and to establish evaluation level of public management system using policy evaluation framework for establishing perspective and systemic level. Also, this study constructed basic principles as expanded concept like Public, expertise, participation, rationality, and sustainability based on previous studies and expert opinion. AHP analysis results are following. In case of upper level, post management and continuity are important factors. Also in case of under level, making stable economic system, honest operating system, reducing development costs, local development with self-sufficiency were important factors. through empirical results, the implications are following. First, public management system needs to develop a consistent principle from planning step to post management. Second, it is essential point that continuous retraining between involved people and drawing residents participate in progress activity. Third, when evaluating public management system, it is need that emphasize non-physical factor like conflict issue between stakeholder.

국가에서는 수해예방 및 주민들의 삶의 질 향상을 위해 다양한 하천사업을 수행한다. 국토교통부의 경우 매년 막대한 예산을 투입하여 하천정비 및 재해복구사업 등을 추진 중에 있으나, 체계적인 공사관리와 산출물의 전산화를 위한 시스템은 부재한 실정이다. 현재 건설사업정보시스템(건설CALS)을 통해 하천공사에 관한 정보를 확인할 수 있으나 총 공사비, 참여업체 등 기본적인 정보만을 제공하고 있으며, 공정관리 및 예산정보에 관한 상세한 내역을 확인 및 관리할 수 있는 기능은 부재하다. 이러한 문제를 해결하고자 본 연구에서는 하천사업(공사)관리시스템의 필요성을 제시함과 동시에 우선적으로 하천사업 공종 표준화를 수행하고자 한다. 현재 건설공사표준품셈을 통해 건설공사의 공종을 확인할 수 있으나 '제2장 하천공사' 내에는 사석, 돌망태, 하천호안공에 관한 정보만을 담고 있다. 하천공사 공종 표준화를 진행하게 될 경우 공종별 공사 세부정보에 대한 관리가 가능해지며, 현재 하천을 관리 중인 국토교통부, 지방국토관리청 및 지자체 등 하천사업을 수행 중인 기관의 시스템 활용도를 제고할 수 있다. 하천사업 공종표준화를 위해 우선적으로 현재 건설공사표준품셈, 도로대장 전산화 입력지침 등기 수립된 지침 및 기준을 통해 건설토목공사 시의 공종을 조사·분석한 후, 하천공사 준공보고서 및 감리보고서 등 공사 관련 자료를 활용하여 하천공사에 주로 수행되는 공사들에 관한 종류를 도출하였다. 이후 건설토목공사 공종과의 비교·분석을 통해 하천공사에서 주로 수행되는 공종을 도출·표준화하는 작업을 진행하였다. 본 연구에서 제시한 하천사업 공종의 경우 향후 하천사업(공사)관리시스템 개발에 활용이 가능하며, 하천공사 관리의 효율성을 극대화할 수 있다.

Providing the reasonable construction cost at the initial stage of the rural development project, is a kety factor of the each step of project , such as propriety analysis , cost planning , design, and planning the progress of work. The explainable construction cost can be estimated at the early stage using the actual cost data by statistical analysis. In this study, the influence factors are extracted by factor analysis with the actual cost data of rural development project, object cost model is developed by multiple regression analysis, and verify the developed cost model by Monte-Carlo simulation .
