The purpose of this study is to formulate various improved working schemes in determining the definition of non-permissible activities to strengthen the practical implementation and operation of the integrated coastal management plan for regional self-governing authorities In this study, non-permissible activities indicate any activities which should be restricted according to the coastal functions of five different sectors in the regional plan for coastal management. Coastal management plan, are classified into four areas along the coast to use direction. It prohibited and support matters of another coastal exploitation each area. If you want to set the coastal area, has already been specified in the regional and global based on that region Land use planning and urban planning. When additional area settings in some cases may lead to conflicting results. Analyzes the factors to consider about the range and use areas set of in coastal management, It is necessary to strive for deriving a scheme to solve the existing contradiction between the state of the local - area specified problem. With the help of marine spatial planning and pointed out institutional and urban planning system to be utilized in land in the ocean for a more accurate and efficient coastal management, and registered the coastal areas, there is a need to manage. Land -use planning, consideration of another consultation body organization that is able to develop a plan that was comprehensive and marine spatial planning, The contradiction consider to specify the various areas and regions where other specific identification method is determined, Setting the range of coastal waters (within 3 nautical mile), I was exploring the coast registration scheme and registration target, etc.

In September 2008, the Korean government has legally pronounced criteria to designate the Impact Fee Zone on the basis of the population increase rate. Taking the Dongtan Newtown in Hwasung City as the case, the study tries a grid analysis method to figure out the cells that exceed the legal population increase rate criteria. The study then performs scenario analyses that try to envelope the cells into spatially contiguous groups based on their degrees of stepwise adjacency either by the cell buffer or the cell distance standards. By overlapping the selected cell groups over the actual land-use map for the vicinity, it is found that the selected areas reasonably coincide with the blocks of the high population density in the Newtown.

This study aimed to provide practical measures to help the relocation of schools by investigating and analyzing the trend of increasing number of students in the old city, the location of schools in the school district, and the distance to school. To this end, a model for the relocation of schools in the old city was derived by conducting prior research surveys and case area analysis. In order to derive the Planning Model of Elementary School Relocation in the Old city, the study first analyzes the mid- to long-term changes in the target area and the number of students by school, and places schools through a regionally customized school layout grid model presented in the study. In addition, the school relocation plan needs to be implemented by establishing a mid- to long-term school relocation plan in connection with the nearby urban readjustment project, etc.

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.

In accordance with the increased demand for ocean use, the Marine Spatial Planning system was introduced to rationally allocate ocean space, under which fishing activity protection zones have been designated to protect fishery activities and promote fishery resource protection. However, fishing vessels that mainly sail in fishing activity protection zones are exposed to risk, such that they account for about 70% of marine accidents that occur in Korea, Proper risk management is thus required. This study aims to analyze marine accidents in fishing activities protection zones and port and navigation zones to secure the safety of fishing vessels passing within fishing activity protection zones. To this end, the traffic volume in marine use zones was investigated, and marine accidents were investigated by ship type, accident type, tonnage, accident cause, and loss of life. Analysis determined that most of the marine accidents per unit area of each type occurred in port and navigation zones, but overall most marine accidents occurred in fishing activity protection zones. In particular, it was found that traffic safety management was necessary because many human accidents occurred.

상수도 관망해석에 있어 수요량 추정 방법은 자료의 형태와 관망해석의 정확도 추구 정도 등에 따라 다양한 방법으로 추정할 수 있다. 통상 상수도관망해석을 수행할 때에 사용되는 수요량추정 방법은 과거사용량을 추세분석하여 장래 계획에 필요한 목표연도까지의 원단위를 산정하고 이 자료를 바탕으로 행정구역상 동단위나 병합계량구역(Block system)단위까지 수요량을 산출한 후 수요량 산출 구역 내 해석 관망상에 위치하는 격점 또는 관로에 적정한 수요량을 분배하는 방법을 사용한다. 결국 산정된 수요량 자료는 행정동 단위나, 병합계량구역 단위 정도의 수요량을 산출하고, 해당 구역내에 분포하는 관망 구성상 절점수에 따라 등분하여 배분하거나, 절점이 담당하는 면적별로 수요량을 산출하여 관망해석을 실시하게 된다. 이러한 방법은 작업시간이 오래 걸리고 수요량 추정 단위에 따라 정확도가 달라지는 문제가 있다. 본 연구에서는 인천시를 대상으로 MIKE-NET 프로그램에서 제공하고 있는 수요량 배분 기능을 이용하여 각 절점의 수요량을 배분하는 방법과 기존 수요량 배분 방법을 비교함으로 수요량 적용 방법이 배수관망해석에 미치는 영향을 살펴보았다.

The time for evacuation of residents in emergency planning zone(EPZ) of Uljin nuclear site in case of a radiological emergency was estimated with traffic analysis. Evacuees were classified into 4 groups by considering population density, local jurisdictions, and whether they ate residents or transients. The survey to investigate the behavioral characteristics of the residents was made for 200 households and included a hypothetical scenario explaining the accident situation and questions such as dwelling place, time demand for evacuation preparation transportation means for evacuation, sheltering place, and evacuation direction. The microscopic traffic simulation model, CORSIM, was used to simulate the behavior of evacuating vehicles on networks. The results showed that the evacuation time required for total vehicles to move out from EPZ took longer in the daytime than at night in spite that the delay times at intersections were longer at night than in the daytime. This was analyzed due to the differences of the trip generation time distribution. To validate whether the CORSIM model fan appropriately simulate the congested traffic phenomena assumable in case of emergency, a benchmark study was conducted at an intersection without an actuated traffic signal near Uljin site during the traffic peak-time in the morning. This study indicated that the predicted output by the CORSIM model was in good agreement with the observed data. satisfying the purpose of this study.

최근 기후변화에 따라 우리나라 해수면 상승률은 평균 2.48mm/yr로 가파르게 상승하고 있다. 동해의 해수면 상승률은 2.69mm/yr 로 전세계 평균 해수면 상승률인 2.0mm/yr 보다 높게 나타나 해수면 상승에 의한 해수침투 피해가 증가할 것으로 예상된다. 해수침투로 인해 1차적으로 연안지역의 해수침투 영역이 증가하고, 지하수의 오염, 농작물의 염수 피해, 산업활동의 제약 등 피해 범위가 지역 사회 범위로 점차 증가한다. 한정된 자원에서 해수침투를 예방하고 피해지역을 줄이는 것에는 많은 어려움이 있다. 이를 위해 동해 연안지역의 행정구역을 대상으로 정량적인 분석을 통하여 해수침투에 취약한 지역을 선정하고 대비하는 것이 가장 효율적인 방법이라고 볼 수 있다. 본 연구에서는 해수침투에 영향을 미치는 인자들을 수집하고, 취약지역을 평가하여 분석하였다. 동해 연안의 11개 시 군 행정구역을 대상으로 해수침투에 영향을 미칠 수 있는 인자를 선택하고 자료를 수집하였다. 수집된 자료는 Re-scale 방법을 이용하여 표준화 하고 엔트로피 방법을 이용하여 산정된 가중치를 각각의 인자에 적용하였다. 산정된 해수침투 취약성 지수는 동해안을 대상으로 하여 각 행정구역에 대한 상대적인 취약성을 나타낸다. 최종적으로 산정된 취약성 지수를 동해안의 행정구역이 도시되어 있는 지도에 나타내어 취약한 지역에 대하여 해수침투 방지 대책 및 시설 보강 계획을 세운다면 해수침투 피해에 효율적인 대처가 가능할 것으로 예상된다.

Gyeongsangbuk-do moved its provincial office in October, 2015 and has been building a new town with a goal to construct a truly self-sufficient city with the population of 100,000 people before 2027. However, a new town tends to be dualized in terms of its administrative districts, so it is raising a lot of problems regarding from city construction up to operation. In order to solve those problems, this author has selected Si Gun Gu integration that was chosen as a major task to do in 2012 among the basic plans to revise the local administration system announced by the promotional committee to reorganize administrative districts as the range of this research and analyzed how it is going on in Andong-si and Yecheon-gun where a provincial office new town is being constructed. The main contents of this study regard the theoretical model to reform the local administration system, basic plans to revise the local administration system, and necessity and directions for reorganizing administrative districts in Andong-si and Yecheon-gun. Based on that, this author suggests integration of administrative districts as a way for a provincial office new town to establish its identity and grow as a sustainable, new growth focus city in Gyeongsangbuk-do.

The KTX station is one of special generators that produce a lot of trips caused by special land use such as university, airport, and super shopping mall. Special generators need special attention in developing travel demand models since the standard trip generation and distribution model in the conventional four-step approach do not provide reliable estimates of their travel patterns. New modeling approach, activity-based model, considering travel behavior of person, seem to be more appropriate for those special generators. Thus, this study introduces a spatial-temporal activity-based approach and how activity-based approach can be applied to estimation of travel demand at KTX stations.
