This study is aimed at classifying different types of parks in Gwang-Ju city and providing efficient Planning and guidelines to satisfy the needs of park users. The first stage of this study was accomplished by site surveys of neighborhood parks in Gwang-Ju where park types, locations, neighboring conditions, park layout, and other physical environments were surveyed for the specific status of parks. With those basic data, urban neighborhood park types were classified into different categories: 1) urban neighborhood parks; 2) riverside neighborhood parks; and 3) natural(mountain side) neighborhood parks. For the second stage of this study, behavior patterns and satisfaction were investigated to provide empirical data on the relationship between the physical environment and human behavior. The main findings of this study can be summarized as follows: 1. The highest level of satisfaction for the users of urban neighborhood parks in Gwang-Ju city is the accessibility of the parks which are small but located in neighborhoods, The users tend to visit the nearby parks regardless of size. 2. The users have relatively high levels of satisfaction for urban neighborhood parks which have a lot of green zones or park facilities. Therefore, the park planner should consider the natural environment in the park area and should reconsider the type of park in the planning process. 3. The different types of urban neighborhood parks in Gwang-Ju city do not affect the level of satisfaction and the motivation of park visits. However, the accessibility of the parks is the most important factors of users' satisfaction regardless of the type of the park. 4. The level of user satisfaction for all of the urban neighborhood parks in Gwang-Ju city indicates that the users have a relatively low level of satisfaction. Especially, 26.2% of the users have a high level of dissatisfaction. The new parks, which have recently been developed, have a higher level of satisfaction than the old parks which have a lack of facilities, insufficient maintenance, and poor management planning in the park. 5. As a result of factor analysis, all city neighborhood parks showed a similar tendency with urban type parks, but showed a tendency that was different from the other park types.

We consider facility layout problems, where mn facility units are assigned into mn cells. These cells are arranged into a rectangular pattern with m rows and n columns. In order to solve this cell type facility layout problem, many approximation algorithms with improved local search methods were studied because it was quite difficult to find exact optimum of such problem in case of large size problem. In this paper, new algorithms based on Simulated Annealing (SA) method with two neighborhood generation methods are proposed. The new neighborhood generation method adopts the exchanging operation of facility units in accordance with adjacent preference. For evaluating the performance of the neighborhood generation method, three algorithms, previous SA algorithm with random 2-opt neighborhood generation method, the SA-based algorithm with the new neighborhood generation method (SA1) and the SA-based algorithm with probabilistic selection of random 2-opt and the new neighborhood generation method (SA2), are developed and compared by experiment of solving same example problem. In case of numeric examples with problem type 1 (the optimum layout is given), SA1 algorithm could find excellent layout than other algorithms. However, in case of problem type 2 (random-prepared and optimum-unknown problem), SA2 was excellent more than other algorithms.

This Study is to analyse the community-consciousness depending on the location type of the neighborhood facility in apartment complex, in order to set up the fundamental criteria for the location type which can increase the community-consciousness. For the purpose of this study, Shopping center, Playground and Resting Area are selected among the neighborhood facilities and they were analysed on the basis of the Belonging-Sense, Affection-sense and the personnel Interchange. The results of this study are as follows: Shopping center should be located in the Main-Enterance of Apartment Complex and be constructed as low building along the street. In case of the Playground that was compared with the Central type and Decentral type, the Central type is proper for the increasing of community-consciousness. In case of the Resting Area that was compared with the Mixture type involving a playground and Independent type except for a playground, the independent type is acceptable for the location-type to increase the community-consciousness owing to all analyses.

본 연구는 지역사회에 거주하고 있는 우리나라 노인이 어떠한 근린환경 구조 속에서 생활하고 있는지를 규명하고, 노인이 실제 거주하는 근린환경 유형들이 노인의 삶의 만족과 직접적인 관련이 있는지 검증하고자 한다. 이를 위해 지역사회에 거주하고 있는 65세 이상 노인을 대상으로 보건복지부와 한국보건사회연구원에서 2014년에 수행한 "노인실태조사" 자료에서 대리응답을 제외한 본인이 직접 응답한 10,281명의 자료를 분석에 사용하였다. 근린환경 유형을 판단하기 위해 식료품 가게, 의료기관, 행정기관, 복지시설, 대중교통(정류장, 지하철역) 등의 지역사회기관이나 장소까지 도보로 걸리는 시간(분 단위)을 지표로 활용하였으며, 근린환경 유형을 파악하기 위해 잠재프로파일분석을 실시하였다. 분석 결과, 노인이 생활하는 근린환경 유형은 여가 복지 도보제한형(20.3%), 여가 복지 원거리형(15.5%), 균형근접형(7.8%), 상점 교통형(35.0%), 교통근접형(10.1%), 격리형(11.3%) 등 여섯 가지 유형으로 도출되었으며, 앞의 네 개 유형은 도시형에 가까우며 교통근접형과 격리형은 농어촌형에 가까운 특성을 보이고 있다. 근린환경 유형이 노인의 삶의 만족에 미치는 영향을 분석한 결과, 균형근접형에 비해 상점 교통형과 격리형에 거주하고 있는 노인들의 삶의 만족이 통계적으로 유의하게 낮은 것으로 나타났다. 그 밖에 남성보다 여성이, 연령과 교육수준, 그리고 가구소득이 높을수록, 유배우자 집단의 삶의 만족도가 높았으며, 건강상태(주관적 건강, 만성질환개수, 기능상태)가 좋을수록, 그리고 비동거 자녀, 형제자매, 그리고 친구나 이웃과의 연락빈도가 높을수록 삶의 만족수준이 높은 것으로 나타났다. 본 연구는 노인을 둘러싼 근린환경의 구조가 노인의 삶의 질과 직접적인 관련이 있다는 것으로 실증적으로 검증한 연구로서 물리적 근린환경의 구조적인 측면도 고령친화적 지역사회를 구현하는데 고려되어야 함을 보여주고 있다.

The purpose of this study is to determine the suitable illuminance model of an urban neighborhood park. To this end, 1 dependent variable and 11 independent variables were set, and multiple regression analysis was applied to find correlation between variables and the model. The results of this study are as follows; 1) Among 11 independent variables abstracted to study suitable illuminance model of an urban neighborhood park, as a result of analysis on correlation between suitable illuminance of a dependent variable and activity space by using dummy variables, activity type and illuminance by spaces the suitable illuminance required for an urban neighborhood park was much influenced by activity type, and the fact that the activity was not limited to a specific space. 2) As a result of multiple regression analysis, independent variables influencing the suitable illuminance model of an urban neighborhood park were activity space, illuminance by spaces, seated activity, standing activity, and sporting activity. And, for relative contribution of independent variables to suitable illuminance, activity with sporting showed an importance 22 times higher than seated activity. When the central square(Sp_1) of activity spaces was set to reference category using dummy variables, it showed a contribution 52 times higher than sorting space(Sp_7) and the central square as the most important variable. 3) It was analyzed that suitable illuminance of an urban neighborhood part was most influenced by sporting activity but the relative contribution of a sporting space where activity with sporting occurs was least in view of the function of the space. Very high illuminance is required to accept high activity, and if illuminance at a certain space becomes too high, it may influence the illuminance of other spaces, and may consequently have a negative effect on the suitable illuminance of an urban neighborhood park. The results of this study were mainly for teenagers and young adults in their twenties, so further concrete studies which consider gender and a wider age range are needed in the future. Based on subsequent study, suitable illuminance by spaces shall be suggested.

Here, we present a new framework for histogram equalization in which both local and global contrasts are enhanced using neighborhood metrics. When checking neighborhood information, filters can simultaneously improve image quality. Filters are chosen depending on image properties, such as noise removal and smoothing. Our experimental results confirmed that this does not increase the computational cost because the filtering process is done by our proposed arrangement of making the histogram while checking neighborhood metrics simultaneously. If the two methods, i.e., histogram equalization and filtering, are performed sequentially, the first method uses the original image data and next method uses the data altered by the first. With combined histogram equalization and filtering, the original data can be used for both methods. The proposed method is fully automated and any spatial neighborhood filter type and size can be used. Our experiments confirmed that the proposed method is more effective than other similar techniques reported previously.

Let $\Omega$ be a smoothly bounded pseudoconvex domain in $C^{n}$ and let $z^{0}$ $\in$b$\Omega$ a point of finite type. We also assume that the Levi form of b$\Omega$ is comparable in a neighborhood of $z^{0}$ . Then we get precise estimates of the Bergman kernel function, $K_{\Omega}$(z, w), and its derivatives in a neighborhood of $z^{0}$ . .
