It is required impressive expression of urban night environment that makes city as the safe pleasant, convenient place for the economic activity, cultural pleasure and landmarks. This study aims to establish the proper direction to the outdoor lighting in Seoul by analyzing and comparing the lighting situation and policies among Seoul, Shanghai and Yokohama. 1986 Asian Game and 1988 Olympic Game became very important role of activation of outdoor lighting in Korea. Then, outdoor lighting were facilitated in the cultural heritages and bridges along Han river. Millenium Light Plan, Outdoor Lighting Field of Seoul Architectural Award, 2002 Lightscape Local Plan, hosting 2002 World Cup have been good opportunities for the improvement of outdoor lighting in Seoul. In China, outdoor lighting was introduced to the city of Shanghai according to the orders of the president in 1988. Outdoor lighting of Shanghai have created unique lighting with beautiful color and intensive brightness under the direction of city government. Outdoor lighting of Shanghai needs the standard of lighting design and improvement of lighting facilities. Outdoor lighting was introduced to Japan with 1964 Tokyo Olympic games. Urban outdoor lighting plan was carried out in Yokohama in 1986. In Yokohama, outdoor lighting of civilian and public facilities have been harmonized. And the city government of Yokohama established the committee of promotion of outdoor lighting in its government to support and manage the outdoor lighting with corporation of civilian organization. As the result of comparative analysis on Seoul, Shanghai, Yokohama, Seoul Metropolitan Government needs the criteria and incentive system of outdoor lighting.

This study selected Nakdong River basin zone in Daegu as an example area to conduct landscapetope classification and aesthetic value assessment of landscape according to the classified landscapetope. The main result of this research can be summed up as following. First, the result of landscapetope type classification showed 28 types of landscapetope including complex residential area (AA), natural stream type with copious vegetation (BA), forest type centered on mixed forest of soft and hardwood (EB) along with 129 types of imputed specific landscapetope. The result of the total first assessment using B-VAT showed the first grade 10 types, II grade 4 types, III grade6 types, IV grade 3 types, 5 types for V grade with the lowest value. The second assessment conducted toward the landscapetope types with the grade higher than the average (including III grade) in the result of the first assessment showed that there are 66 spaces for the sites (1a, 1b) with special meaning for aesthetic landscape evaluation. And also, there were 69 spaces for those (2a, 2b, 2c) with meaning for aesthetic landscape evaluation. The design model of this research is largely divided into improvement goal and specific execution plan. First, the improvement goal is divided into 6 categories including conservation area, complementary area, and restoration area, and the specific execution plan is divided into 14 categories including special landscape management area, general landscape management area, conservation of hill areas with optically good condition. A comprehensive master plan was suggested by directly applying the set landscape planning model to the subject place of this research.

The Ministry of Maritime Affairs and Fisheries has been promoting the 'Fishing Village Specialization Capacity Enhancement Project' to pursue sustainable development of villages such as income generation by using local tangible and intangible resources led by local residents at the village level since 2013. For the fishing village-Specialization capacity enhancement project, six training sessions (mainly in the village unit) are selected by the public offering method, and the project (income generating business, village development project, etc.) is developed for the selected village residents. It has a process of establishing a village project plan (a preliminary plan for village development or a sixth preliminary industrialization plan) based on the training of experts 5 times, practice or excursion 1 time). In this study, four villages in Gangwon-do fishing villages (two coastal villages and two inland water villages) were surveyed on the perception and satisfaction of fishing village development projects before and after training. The survey analysis was conducted by dividing the analysis of resident capacity and satisfaction into personal, interpersonal, and social dimensions. The survey was conducted by distributing a survey before and after training, and a 1:1 survey was conducted according to the residents' cognitive status. Based on the survey, factor analysis, reliability analysis, and analysis using the corresponding sample t-test showed an increase of 0.02 for Yangyang Mulchi fishing village, 0.11 for Samcheok Jangho fishing village, and 0.36 for Hongcheon River fishing industry, but Yanggu Jinmok fishing industry was -0.29, unlike other regions. As a result of this analysis, it has been empirically proven that provision of training projects through resident participation is a very important factor for the success of the fishing village project. Therefore, rather than fostering local leaders, training and community activities to strengthen personal capacities of residents participating in the project, it is necessary to operate the software business with a focus.

하구둑과 같은 구조물이 설치된 하구역에서는 상류로부터 내려온 하천수와 외해의 조석, 수문의 운영에 따라 복잡한 유출특성을 가지게 되며, 하나의 하구역에 2개 이상의 유역출구가 존재하는 경우 더욱 복잡한 형태의 홍수유출특성을 나타낸다. 이러한 사례로 현재 개발계획이 수립중인 새만금 지역을 들 수 있다. 새만금 지역의 경우 만경강과 동진강 유역에서 하천수가 유입되고 방조제에서는 배수갑문을 통해 하천수를 방류하고 해수유입을 차단한다. 두 하천이 만나는 새만금호 내에는 분리하는 용지가 들어서게 되며, 두 수계의 유출량을 연결수로를 통해 교환할 수 있도록 계획되고 있다. 이러한 연결수로는 평소에는 주운의 역할을 하지만 홍수시에는 두 수계간의 홍수를 소통시켜 홍수를 분담하는 기능을 하게 된다. 따라서 하구역 내의 치수적 안전성 확보를 위해서는 연결수로에 대한 홍수분담능력을 파악하는 것이 중요하다. 본 연구에서는 연결수로의 통수능에 따른 홍수위 저감효과를 수치해석을 통해 분석하였다. 해석에는 Delft3D를 활용하였으며 해석기간은 배수갑문의 방류가 어려워 최대홍수위가 발생되는 소조기로 설정하였다. 새만금종합개발계획상의 토지이용계획에서는 3개의 연결수로가 계획되어 있으나 연결수로에 의한 홍수위저감효과를 검토하기 위해 해석을 단순화하여 가장 폭이 넓은 수로 1개만 운영되도록 설정하였다. 연결수로의 폭은 동일하게 하고 하상고를 EL.-15m~EL.-3m까지 2m 단위로 변화시켜 다양한 통수능 조건에서의 홍수저감효과를 검토하였다. 수치해석 결과 연결수로의 통수능이 감소하면 두 수계간의 수위차가 증가하면서 배수갑문지점에서의 최대수위도 증가하며, 동일한 수위차라 하더라도 통수단면적에 따라 유속의 영향으로 홍수위 저감효과도 변화한다는 것을 확인하였다. 또한, 통수단면적이 증가하더라도 홍수위 저감효과가 발생하지 않게 되는 통수단면적도 분석하여 제시하였다. 본 연구결과는 향후 연결수로 설계시 기초자료로 활용될 수 있으며, 준설로 인한 공사비를 최소화하면서 홍수위 저감효과는 극대화할 수 있는 최적 연결수로를 설계할 수 있을 것으로 기대된다.

In the circumstances being continuous the unusual weather in the world, the city of Seoul has been devastating flood damage in July 2011, because of the heavy rainfalls. Along with expensive repairs to property, thousands of flood victims occurred; it is difficult to estimate the direct and indirect economic damages in city. Recently, as a part of the flood protecting measures, there are being discussed about the deep underground flood drainage tunnel, underground regulating reservoirs, permeable pavement, infiltration facility, river improvements, diversion channel, sewer pipe and ditch improvement and so on. Therefore, it is useful to make the plan of flood protecting measures more and more cost-effective and rational methods by considering the similar flood measures and constructions in the mega cities like Seoul.

It is a difficult task for decision makers(DMs) to choose an appropriate release plan which balances the conflicts between water storage and hydro-electric energy generation in a multi-reservoir operation problem. In this study, we proposed a DEA-based ranking procedure by which the DM can rank the potential alternatives and select the best solution among the Pareto-optimal solutions. The proposed procedure can resolve the problem of mix inefficiency that may cause errors in measuring the efficiency of alternatives. We applied the proposed procedure to the multi-reservoir operation problem for the Geum-River basin and could choose the best efficient solution from the Pareto-set which were generated by the Coordinated Multi-Reservoir Operating Model.

The thesis of this analytical study includes 1) the generation of annual and monthly discharge regarding single hydrological variable at single site, 2)comparsion with the historical records and the generation, and 3) changing the monthly generatied discharge into annual. The conclusion of this will be used for the future plan for water resources development. Annual discharges at waegwan are characterized by log-normal distirbution and persistence-absent. Also, the random number generator causes the errors in the generation of annual discharge. The serial correlation coefficients of the generated annual discharge have less value than that of historical records, while the correlation coefficient and slope in January have(+) value and opposite to historical record. To change the monthly generated discharge into annual is not proper.

After the legal foundation for the Total Load Control System (TLCS) process is embedded in integrated water management counterplan for 4 major river basins (1998), Kyunggido Kwangju City prepared the implementation plan of TLCS at first time. There is little difference between TLCS and TMDL(Total Daily Maxium Loading; U.S.A). TMDL is applied only when mandatory effluent limitations are not stringent enough to attain any water quality standard. But object of TLCS not only attain water quality standard at distributed watershed but also consider development of area at non-distributed watershed. For applying of systematic and consistent TLCS, we need to establish a system integrated watershed and point source, non-point source and assessed massive database easily. Now we are study on applicable possibility of BASINS on Korea, we think that BASINS's tool and many models are more easily apply to TLCS, so we recommend TLCS will be applied using BASINS.
