본 연구는 도시의 주택 재개발사업으로 인해 점차 해체되고 있는 지역 공동체의식의 회복을 위한 하나의 대안으로, 공동주택 중앙광장의 물리적 입지에 따른 구조적 특성에 주목하고자 한다. 이는 중앙광장이 단순히 공동주택 거주자들만을 위한 내적이고 자기 완결형의 공간으로 기능하는 것이 아니라, 주변지역 주민들과 소통하고 교류하며 지역 공동체의 거점으로 활성화된 열린 공간으로써 그 범위가 확장될 수 있음을 의미하는 것이다. 연구의 가설은 다음과 같다. 공동주택 중앙광장의 물리적 입지에 의한 구조적 특성은 주변 지역에 대한 공동주택 거주자들의 심리적 개방성과 주변지역 거주자들이 갖는 심리적 접근성, 그리고 지역 공동체의식에 각각 영향을 주게된다. 또한 이러한 개방성과 접근성으로 표현되는 심리적 거리는 지역 공동체의식과 상호 밀접한 관계를 형성한다. 연구를 위해 우선 중앙광장이 단지 외부를 향해 열린 정도에 따라 이를 열린 구조와 닫힌 구조로 유형화하였다. 이를 토대로 동일 지역 안의 비슷한 조건을 가진 신림 푸르지오와 방학 대상타운 현대, 그리고 관악 푸르지오와 방학 삼성 래미안 1단지를 대상지로 선정, 각각 공동주택 거주자들과 주변지역 거주자들의 두 개 집단으로 분류한 후 총 여덟개의 집단을 대상으로 설문 조사를 시행하였다. 지역 공동체의식과 심리적 개방성, 심리적 접근성의 측정 등을 실시한 결과 위의 연구 가설들이 모두 성립함을 알 수 있었다. 즉, 열린 구조의 중앙광장에서 지역 공동체의식과 심리적 개방성, 접근성 등이 각각 높게 나타났으며, 심리적 개방성과 접근성이 높은 경우 지역 공동체의식 역시 높은 것으로 나타났다. 본 연구는 중앙광장의 물리적 입지성과 지역 주민들의 심리적 개방성, 접근성, 지역 공동체의식이 상호 연관관계를 형성하고 있음을 구체적인 대상지를 통해 분석, 검증하였다는 데에 의의를 두며, 향후 실천적인 중앙광장의 계획과 조성을 위한 하나의 이론적 근거가 될 수 있을 것이다.

This study is designed to examine characteristics and types of basic landscape design established by 7 local governments in Jeollanam-do and its availability as the index of landscape administration and present a guideline with view landscape plan of local governments. The results of this study are described below. In case of view landscape, while Korean cities have not many historical assets like landmark, they have locational characteristics with mountain or coast in the center or surroundings of downtown. Therefore, since view landscape has many cases of restricting individual property rights as well as having a value as public property of city which makes recognition of sharing city, it is very sensitive problem and establishing guideline of it is needed. But, it was found that view landscape plan of local governments established location of view spot with the nature of relief viewing downtown or coast from high spot. Selection of viewing objects in view plan require deciding an object as the public property of city and big cities require selection from the zone and small cities must select 1~2 spots from the viewpoint of whole downtown. 3~4 view spots of middle and distant views which makes city community centering around the subject of view must be selected through enough discussion and in case of natural landscape, View shaft or visible rays require setting of range that 30% of viewing objects is seen. View spot or viewing objects should be selected over twice as extra spots through public hearing and civil participation as the process.

Long distance trail or trail system planning is the first important step in transforming your vision into reality. Planning presents a vision for a trail or trail system and brings a comprehensive, long-range perspective. The master plan provides solid, credible recommendations for developing a trail or trail system that is safe, convenient, well used, supported by local residents, practicality to implement, and customized to meet the needs of the community, you will need to follow a logical planning. The key elements of master planning includes site assessment, vision, goals and objectives, routing and design, implementation strategies. Trails or trail systems should provide linkages to popular destinations, safely accommodate a variety of users, and be sensitive to any negative impacts on the natural environment and wildlife. Trails planners also need to think about how the trail, or trail system will function in the future as areas are developed or trail population increases. All of these factors during the planning process will ensure the existence of high-quality facilities for years to come. Project for Nakdong-jungmaek trail planning combine long distance trail with circuit way. That project is a planning brought out the best in each of Tokai natural way and Cotswold way. That is planning which is combined a wooded trail in Tokai natural way with access and facilities improving economy in Cotswold way. Also That planning embraces a core cultural center which is concerned forest or wood to come more people.

The purpose of this study was to analyze the loss of open space of schools in Ulaanbaatar city and found out main causes of the conversion trend of open space to suggest alternatives. 76 designated sites were selected from 118 public schools within 6 districts of Ulaanbaatar city. These 76 schools were eligible for analysis of the open space change between 2005 and 2015 with Google Earth Pro. The results showed that $175,048m^2$ open space was developed and two dominant types of open space conversion were found; 1) constructions of school facilities such as soccer field, extended school buildings, parking lot, sidewalk, and square, and 2) constructions of apartment buildings and service facilities such as community center, pedestrian, sports facilities, and parking lot. Apartment complex development has commonly happened in all districts and caused bigger open space loss than other types of development. Chingeltei district is located in the center of Ulaanbaatar city, and schools in this district lost the biggest open space, $50,036m^2$/35.24% over 10 years. The rate of open space loss seemed to be related to the distance from the urban center and open space loss was an ongoing event in Ulaanbaatar city. This trend would not be improved without a strong regulation, so, in this study, making strict regulations that prevent conversions of open space were suggested to conserve open space in Ulaanbaatar city.

This study assessed the reliability of the agricultural water supply based on future climate change scenarios, and suggested plans to improve the reliability in order to promote the adaptability of irrigation water in agricultural reservoirs to climate change. The assessment of agricultural water supply reliability was performed on reservoirs which had a lower water quantity than their design basis and which had recently been subject to drought. In other words, from the irrigation districts of main intake works among the reservoirs managed by the Korea Rural Community Corporation, 1~2 districts in each province-that is, a total of 13 districts -that were recently designated as a district for securing agricultural water (drought prevention district) were selected. Climate change scenarios were applied to the selected districts to analyze their future water supply reliability compared to the current level. All districts selected showed a drought frequency of 4 years or shorter, which demonstrated the need to establish climate change response plans. As plans for responding to climate change, a plan that utilizes supplemental intake works to reduce the area of the irrigation districts of main intake works, and another one that increases the capacity of main intake works were adopted to reanalyze their water supply reliability. When the area of the irrigation districts of main intake works was reduced by about 30~40%, the drought frequency dropped to more than 10 years, securing the reliability of water supply. To secure the reliability by increasing the capacity of main intake works, it was calculated that about 19,000~2,400,000 tons need to be added to each reservoir. In addition, climate change response plans were suggested to improve the reliability of the water supply in each district based on the results of economic analysis.

Purpose: To estimate the prevalence of periodontitis in Korean adults and to examine the associations between periodontitis and known risk factors. Methods: Using Korean National Oral Health Survey 2006 data, a total of 4,263 people who had taken oral examination, interviewed by questionnaire, and aged 18 or older were sampled. The prevalence of periodontitis measured by Community Periodontal Index (CPI) was calculated and the differences in prevalence according to known risk factors (age, sex, monthly income, education, residential area, tooth-brushing frequency, regular dental visit, smoking, and diabetes) were examined with chi-square test. Logistic regression analysis was performed to see the effects of each risk factor on the risk of having periodontitis. All statistical approaches were reflected national sampling design using Survey procedures in SAS 9.1. Results: The overall prevalence of periodontitis in Korean adults was 10.3%. There existed statistically significant differences in crude prevalence for periodontitis according to the all risk factors. In logistic regression, older age groups (O.R.:2.94-3.71), people living in rural area (O.R.:1.87), and current smokers (O.R.:1.77) were significantly prone to have periodontitis. People who earned monthly income of more than 2 million Korean won (O.R.:0.64) and brushed their teeth two or more times per day (O.R.:0.60-0.62) had significantly lower risk of having periodontitis. Conclusions: About 10% of Korean adults had periodontitis in 2006. People who were older, living in rural region, in lower income status, smoking, less tooth brushing were more likely to have periodontitis.

This study was carried out to safety evaluation, the practical application and improvement of design method of the agricultural reservoir due to raising embankments. Also, it was to compare and analyze the pore water pressure (PWP), seepage (leakage) quantity and piping phenomenon according to high water table and rapid drawdown. The seepage analysis by finite element analysis was used for steady state and transient condition. The pore water pressure distribution for steady state and transient condition showed positive(+) PWP on the upstream slope, it was gradually changed negative(-) PWP on the downstream slope. The PWP in the core ranged from 100 ~ -33 kPa, the seepage line in the incline-type core suddenly decreased towards the lower levels from the higher levels. The PWP according to rapid drawdown is remained in the vicinity of the upstream slope, therefore, it is investigated to be in an unstable state by the slope stability analysis. The PWP after raising embankments showed smaller than in the before raising embankments. It was likely to be the piping phenomenon because the gradients in the before raising embankments showed largely at downstream slope, and the stability for piping in the after raising embankments increased stable state. The seepage quantity per 1 day and the leakage per 100m for the steady state and transient condition appeared to be safe against the piping. It reduced slightly regardless of the transient condition before the raising embankments and it decreased largely about 2.4 times in the early days after the raising embankments.
