Recently, Several Mega project are been performing as a multi-dimensional development project in Korea, but some problem has been revealed about deficiency of the history, experience, and skill. A multi-dimensional development project require the technology which can manage mega project to its specific at the level of program management. predicting schedule and schedule management are the most important for mega project, been performing over several years. This research shows the method of predicting and planning schedule in the early stage as a pre-study on developing a technology of schedule management. First of all, it presents the development of database considering the specific of mega project that can accumulate the history of schedule and search the schedule according to the type of single and multi building. Also it suggests the method of prediction schedule by creating scenarios according to owner requirements and cash flow, affecting schedule management in the early stage, and the shortening possibility of schedule duration using CCPM theory.

The apartment reconstruction projects have the proper functions such as residential environment improvement and the new housing allocation system; however, intention of the projects are distorted by the combination of factors, like failure of relocation of the original occupants and income redistribution, speculation in real estate, sharp rise in housing price, disputation between various interested parties, inadequate system and etc and it makes the projects unable to go well. Disputations and litigations are due to spread of the small conflict. As a result of the problems, it could not going smoothly and that lead to increase or stop the period and cost. This study is to estimate the period and cost using the conflict index so as to prevent and solve the problem which is among the conflict in the reverse functions. The conflict index has estimated focus on the conflict impact and the period and cost has been estimated using an variable independent including the conflict index. Also, estimated the conflict index and estimate of the period and cost are able to succeed with a minimum of disputation and money.

Public-Private-Partnerships tend to be committed high project development cost and recover the cost through future revenue during the operation period. In general, long-term concession can bring on more revenue to private investors, but short-term concession less revenue due to the short recovering opportunities. The concession period is usually determined by government in advance or by the private sectors's proposal although it is a very crucial factor for the PPPs. Accurate traffic forecasting should be most important in planing and evaluating the operation period in that the forecasted traffic determines the project revenue with user fees in PPPs. In this regards, governments and the private investors are required to consider the traffic forecast risk when determining concession period. This study proposed a model for the optimal concession period in the PPPs transportation projects. Monte Carlo simulation was performed to find out the optimal concession period while traffic forecast uncertainty is considered as a project risk under the expected return of the private sector. The simulation results showed that the optimal concession periods are 17 years and 21 years at 5.5% and 7% discount level, respectively. This study result can be applied for the private investors and/or any other concerned decision makers for PPPs projects to set up a more resonable concession period.

This study analyzed the influencing factors for urban redevelopment projects with a relatively long project duration in the context of Seoul's increasing urbanization rate and aging. Among the business areas that have been designated since 2005 and have been approved for the management and disposal plan of the entire Seoul area, 75 business areas have been set as targets. A hedonic price model was used to analyze the project area, economic, and locational characteristics as independent variables with the project duration from designation of zones to approval of management and disposal plans as dependent variables. As a result of the analysis, the smaller the project area, the larger the area occupied per union member, the larger the land price change rate, and the smaller the KOSPI index, the shorter the required period. This study has the distinction of empirically analyzing the effect of characteristic variables considering size and economic and locational characteristics on period. It provides implications that the area of the business area, the number of union members, and economic conditions should be considered when establishing a business area.

기후변화로 정상적인 물 순환 체계가 변화되면서, 건천화로 하천의 정상정인 기능이 어렵게 될 것이다. 농업용 저수지의 둑 높이기 사업으로 수자원의 저류공간이 증가되었고, 확보된 수자원을 기후변화에 대응해 하천유지유량으로 활용 할 수 있게 되었다. 본 연구에서는 기후변화 시나리오 RCP 8.5를 기반으로 임고 저수지의 둑 높이기 사업 전과 후의 공급 가능한 하천유지유량을 평가하였다. 하천유지유량의 공급은 일별 일정량을 공급하도록 하여 이수안전도 90%를 만족하도록 설정하였고, 상시공급과 갈수시 공급으로 구분하여 분석한 결과는 다음과 같다. 첫째, 둑 높이기 사업 전에 하천유지유량의 공급 없이 용수공급 능력을 분석한 결과, 2025s기간, 2055s기간, 2085s기간의 이수안전도는 각각 100%, 93.3%, 96.7%로 분석되어 농업용수의 공급 능력은 충분한 것으로 분석되었다. 둘째, 미래 2025s기간, 2055s기간, 2085s기간에 대하여 둑 높이기 사업 전, 농업용수 공급과 함께 하천유지유량을 상시 공급하였을 경우에는 각각 일별로 3.7천$m^3$, 1천$m^3$, 1.2천$m^3$ 공급 가능하였고, 갈수시만 공급 하였을 경우에는 각각 일별로 7천$m^3$, 2.2천$m^3$, 3.5천$m^3$ 공급 가능한 것으로 분석되었다. 셋째, 미래 2025s기간, 2055s기간, 2085s기간에 대하여 둑 높이기 사업 후, 농업용수 공급과 함께 하천유지유량을 상시 공급하였을 경우에는 각각 일별로 10.5천$m^3$, 4.5천$m^3$, 7천$m^3$ 공급 가능하였고, 갈수시만 공급 하였을 경우에는 각각 일별로 16.6천$m^3$, 7천$m^3$, 12.2천$m^3$ 공급 가능한 것으로 분석되었다. 결론하여 농업용수 공급능력이 충분한 임고 저수지는 둑높이기 사업 후 확보된 수자원을 하천 유지유량으로 공급하면, 증고사업 전보다 상시공급일 경우에 2.8-5.8배, 갈수시 공급일 경우에 2.4-3.4배 많은 양을 공급 할 수 있는 것으로 나타났다.

Although self-sufficiency program participants' alcohol problem is widely recognized among social workers in the field, it has not been received much attention. The purpose of this study is to explore the relationship between alcohol problem and self sufficiency among the participants. A total of 281 participants were participated in this study. Significant relationships between alcohol problem and self sufficiency were not found in bivariate analysis. However, the moderating effect of alcohol problem on the relationship between the length of participation and willingness for self sufficiency was statistically significant. Among the participants with alcohol problem, the length of participation was positively related to willingness for self sufficiency. The result on the moderating effect of alcohol problem on the relationship between the length of participation and willingness for self sufficiency has been never mentioned in previous studies.
