Urban parks create the natural landscape of the city and offer a space for city residents to stay healthy and take a rest. They are also urban facilities designed to improve city dwellers' emotional aspects. Currently, urban parks need qualitative management as well as quantitative supply due to changes in the national land and urban policy paradigm, and a shift in perspective to consumer-centeredness is needed. In this study, the service levels of urban parks for citizen were evaluated: (1) quantitative supply adequacy was analyzed based on the urban population, and (2) the qualitative evaluation of the parks were conducted. Based on the evaluation, the appropriateness of the arrangement of urban parks is judged by comprehensively analyzing the quantitative and qualitative aspects. As a result of the evaluation of service levels of urban parks, the highest serviced urban parks were found in urban housing development sites and recently established parks. In addition, it was found that the recently created parks improved the qualities of the parks by installing various facilities. If the quantitative and qualitative aspects of urban park service supply are comprehensively analyzed and applied through this research method, it will be a more effective park and green space plan.

근대적 기상관측이 시작된 1905년 이후 우리나라의 연평균 강수량은 증가하고 있으나 강수량 변동폭 또한 커지면서 최갈수 기간의 영향을 받는 댐 등 대규모 수공구조물의 용수공급능력은 감소되고 있다. 또한 지역별 강수량과 인구 편차로 공간적으로 이용 가능한 수자원의 불균형이 발생하고 있어 지역적인 물 공급의 안정성과 형평성은 여전히 취약한 상황이다. 하지만 사회적 공감대 형성이 쉽지 않은 대규모 수자원개발 추진은 어려운 여건이며 국민들의 안전하고 맑은 물에 대한 수요 또한 지속적으로 증대되고 있어 이를 해소하기 위한 다각적인 대책 마련이 필요한 상황이다. 본 연구에서는 기 확보된 수자원의 효율적이고 공평한 활용을 위해 국내 용수공급의 중추적인 역할을 담당하고 있는 댐을 대상으로 댐간 연결을 통한 용수공급 방안을 제시하였다. 이를 위하여 소양강댐, 충주댐 등 다목적댐 16개 및 광동댐, 영천댐 등 용수댐 12개 총 28개댐의 용수공급능력 평가와 장래 용수수요량 조사를 실시하였으며 장래 용수부족 지역 해소를 위한 상시공급과 극한가뭄 등 재난 대처를 위한 비상시공급 방안을 검토하였다. 상시공급은 댐 용수공급능력 평가를 통하여 기본계획공급량 대비 여유수량을 갖는 댐에서 장래 용수수요 증가, 용수공급능력 감소 등으로 공급 용수가 부족한 인근 댐으로 공급하는 방식이며 용수 공급량은 저수지 모의운영을 통하여 양댐의 이수안전도(분석 기간중 1회에 한하여 물 부족 허용)를 충족시키는 수량을 산정하였다. 비상시공급은 타수계 및 근거리간 연결, 가뭄 예상지역을 기준으로 대상 댐을 검토하였으며 용수 공급량은 공급댐의 유지용수와 관개용수를 이용하여 공급받는 댐의 생 공용수 20% 공급가능시 공급량으로 산정하였다. 검토 결과 상시공급은 소양강댐에서 횡성댐으로 86천$m^3$/일, 장흥댐에서 주암본댐으로 127천$m^3$/일, 남강댐에서 수어댐으로 $140m^3$/일, 비상시 공급은 충주댐과 대청댐, 충주댐과 안동댐간 각각 500천$m^3$/일 공급을 통하여 장래 용수부족 지역의 물 부족 해소와 극한가뭄 등 비상상황의 대처가 가능한 것으로 분석되었다. 본 연구는 기후변화와 사회가치적으로 변화하고 있는 수자원 환경에 능동적으로 대처하기 위한 대책의 일환으로 고안된 것이며, 향후 유역간 물 이동에 따른 현행 수리권제도 및 어류, 수질변화에 따른 환경영향 등에 대하여 추가적인 연구가 필요할 것으로 판단된다.

The guidelines for the district unit planning(DUP) of detached houses in the area of Misagangbyeon-City (MISA) do not consider the characteristics of the region. Therefore, this study was conducted to analyze the relationship between the blocks and parking lots of the detached houses area. The research results can be summarized as follows: 1) Detailed design guidelines are provided for apartment homes in MISA, but not for detached houses. 2) Apartment home and multi-family house parking lot equivaluation calculations exist in the DUP guidelines, however there are no regulations related to detached houses and the problem of parking for these residents is worsening which causes tension. 3) The DUP guidelines stipulate that the outer wall material of multi-family houses must be glass, however this is a dangerous material for use on the first floor, because cars that park close to this wall. 4) There is a significant risk to elementary and kindergarten students who must walk along the road in the inner blocks where cars are driving quickly. 5) There are a number of issues involved when planning parking lots without considering the characteristics of the area. The local government uses the traditional parking lot codes without considering the current regional characteristics, whereas the number of cars has dramatically increased. 6) The pedestrian mall is not currently being used for pedestrians, because it is full of parked cars due to the lack of parking space.

At a time when the equitable use of urban parks is gradually emerging as a social issue, this study was initiated to expand the influence of urban parks by improving the quality of park services, thereby resolving areas not covered by urban park services. This study targeted the Hangang Park in Seoul, where the qualitative service of parks shows the greatest difference. The influence relationship between the qualitative services of the park and the user's sphere of influence, which indicates the distribution of park users, was proposed to assess the influence of improvements in the quality of service. As a research method, the top three districts and the bottom three districts were selected through the Han River Park user satisfaction survey conducted from 2017 to 2019, and a qualitative service evaluation was carried out. It was derived using the data acquired in September. Afterward, by performing a spatial autocorrelation analysis on the user's sphere of influence, additional verification of the user's sphere of influence was performed numerically and visually. As a result of the study, the user influence in the top three districts, with high-quality service, was stronger and wider than that of the lower three districts. It was confirmed that the quality of service of the park affects the user influence. This shows that to realize park equity, it is necessary to improve the quality of services through continuous management and improvement of individual parks and the creation of new parks. This study has significance in that it recognizes the limitations of research on park services from a supplier's point of view and evaluates the qualitative services of parks from the perspective of actual park users. We propose an alternative to deal with the lower the park deprivation index.

The purpose of this research was to provide the information needed for improving the contents in housing unit of middle school technology and home economic textbook. For this purpose, a survey questionnaire was developed to examine teachers' importance perception of 48 contents in housing unit. A direct survey and an e-mail survey were used to collect data from teachers, and a total number of 233 data were analyzed. Conclusions were summarized as following: 1. Among the 48 contents in housing unit, the average score of teachers' importance perception of the 18 contents on 'interior environment and equipments' was 3.94; the average score of teachers' importance perception of the 15 contents on 'living space plan and use' was 3.78; and the average score of teachers'importance perception of the 15 content on 'housing maintenance and repair' was 3.42. Therefore, the 15 contents on 'housing maintenance and repair' must be revised. 2. Teachers' importance perception of 25 contents, among the 48 contents in housing unit, were significantly differentiated by gender, age, teaching experience, scholastic attainment, subject in charge(technology, home economics, technology and home economics), school type(boys' middle school, girls' middle school, coeducation), and region(city, county). Therefore, the 25 contents, of which importance perception were influenced by teachers' characteristics, must be revised in order to maintain the consistent importance perception. Suggestions were that the team teaching of technology and home economic textbook was more recommendable; that the local situations must be considered in the contents of housing unit and; that the contents of housing unit must be segmented into a minimum unit for the accurate evaluation.

Sevaral problems of administrative area sysem in Korea have been brought up for a long time. Because its frame has remained since Chosun and Japanese colonial period in spite of changing local administrative environment in accordance with rapid industrialization and urbanization. Recent reform of city (Shi)- county (Gun) integration is derived from this argument. But problems which permeate deeply overall system cannot be solved by partial reorganization of Shi-Gun. They may be rationalized only through the reform of the whole system. The aims of this study are to analyze problems of administrative area system entirelr and to discuss the direction of its reform from that point of view. Major problems of administrative area system are summed up into the followings. Firstly, it is found that administrative hierarchies are too many levels. Contemporary administrative hierarchical structure is 4 levels: regional autonomous government (Tukpyolshi, Jik'halshi, Do), local autonomous government (Shi, Gun), two leveis of auxiliary administrative area (Up, Myun and Ri). These hierarchies were established in late period of Chosun which transportation was undeveloped and residential activity space was confined. But today developing transportion and expanding sphere of life don't need administrative hierarchical structurl with many levels. Besides developing administrative technology reduces administrative space by degrees. Many levels of contemporary administrative hierarchical structure are main factor of administrative inefficency, discording with settlement system. Second problem is that Tukpyolshi and Jik'halshi - cities under direct control of the central government as metropolitan area - underbounded cities. Underbounded city discomforts residential life and increases external elects of local pulic services. Especially this problem is Seoul, Pusan and Daegu. Third problem is that Do-areas are mostly two larger in integrating into single sphere of life. In fact each of them consistes of two or three sphere of life. Fourth Problem is metropolitan government system that central city is seperated from complementary area, i.e. Do. It brings about weakening the economic force of Do. Fifth problem is that several cities divided single sphere of life. It is main factor of finantial inefficency and facing difficult regional administration. Finally necessity of rural parish (Myun.) is diminished gradually with higher order center oriented activty of rural residents. First of all administrative area system should corresponds with substantial sphere of life in order to solve these problems. Followings are some key directions this study proposes on the reform of administrative area system from that standpoint. 1. Principles of reorgnization -- integration of central dty with complementary area. -- correspondence of administrative hierarchical structure with settlement system. -- correspondence of boundary of administrative area with sphere of life. 2. Reform strategy -- Jik'halshi is integrated with Do and is under the contol of Do. -- Small Seoul shi (city) which have special functions as captal is demarcated in Seoul tukpyolshi and 22 autonomous distrcts of Seoul tukpyolshi is integrated into 3-4 cities. -- Neighboring cities (Shies) in single sphere of life are intrgrated into single city (Shj). -- Myun and Ri are abolished in rural region and new unit of local administrative area on the basis of lowest order sphere of life into which 3-4 Ries are integrated replaces them.

Purpose: This study analyzes accessibility of 10 hydrogen charging stations in Seoul and identifies areas that were difficult to access. The purpose is to re-analyze accessibility by adding a new location in terms of equity and safety of location placement, and then draw implications by comparing the improvement effects. Method: By applying the location-allocation model and the service area model based on network analysis of the ArcGIS program, areas with weak access were identified. The location selection method applied the 'Minimize Facilities' method in consideration of the need for rapid arrival to insufficient hydrogen charging stations. The limit distance for arrival within a specific time was analyzed by applying the average vehicle traffic speed(23.1km/h, Seoul Open Data Square) in 2022 to three categories: 3,850m(10minutes), 5,775m(15minutes), 7,700m(20minutes). In order to minimize conflicts over the installation of hydrogen charging stations, special standards of the Ministry of Trade, Industry and Energy applied to derive candidate sites for additional installation of hydrogen charging stations among existing gas stations and LPG/CNG charging stations. Result: As a result of the analysis, it was confirmed that accessibility was significantly improved by installing 5 new hydrogen charging stations at relatively safe gas stations and LPG/CNG charging stations in areas where access to the existing 10 hydrogen charging stations is weak within 20 minutes. Nevertheless, it was found that there are still areas where access remains difficult. Conclusion: The location allocation model is used to identify areas where access to hydrogen charging stations is difficult and prioritize installation, decision-making to select locations for hydrogen charging stations based on scientific evidence can be supported.
