The megalopolis citizens are reevaluating the expectant value and the perception of leisure aceording to increasing the level of their incomes, The leisure of citizens is increasing in the aspect of quantity and quality of life nowadays In the site planning of leisure, the concrete understanding about people's choice of a leisure site will be the most important thing, not only for the aspect of improvement of the quality of life but also efficiencies of the land use The purposes of chi study are firstly, to find out the factors which are influenced on a choice of Outdoor leisure facilities in neighbourhood unit and to Compare the Characteristics Of Choice models between the three metropolitan areas, secondly, to predict a limitation of use areal according to the change of a needed time based on the metropolitan's standard choice model For the choice model establishment this research used Logit Model which has been used in the field of the traffic, the tourism and the economics. This research made the results which find out the influencing variables with needed times, the accessibility and the percentage of facilities. The lindtations of use areas come out the results which are predicted according to the change of needed times as a most influencing factors. The range of each preferred leisure facility is about 956 meter distant in the neighbourhood park about 644 meter distant in the pocket park about 604 meter distant in the recreation center, about 628 meter distant in the tennis court about 974 meter distant in the private hob by facility and about 528 meter distant in the library from the apartment unit The recreation center and the library are nearer facilities than the other facilities. But these facilities are surveyed to be more or less influenced by an interesting progran, a context of events and the level of useful facilities, etc.

Since the late 1990s Korean housing authorities and private companies have been pursuing various initiatives towards sustainable neighbourhood design, however, there has been no attempt to examine their progress. This research aims to suggest a sustainability evaluation framework and analyse the progress of sustainability of a cutting edge project: Shinjung Environmentally Friendly Housing Estate Development, using that framework. The results of the analysis suggest that the project failed to make Significant progress in the sustainability evaluation criteria compared to normal projects in Korea and there exist significant barriers: economic/financial barriers; institutional/structural barriers; and implementation barriers within current planning and design practices. Most of the project's design strategies were simply adopted and used as a marketing tool without public participation, sustainability targets or benchmarking for sustainability. Furthermore, most of the responsibility for maintenance was left to residents who normally lack the knowledge, experience, interest and money to carry out such tasks. These problems cause significant concerns over the future success of the project toward sustainability. The experience of the Shinjung project also highlights the need for a more proactive central and local government stance towards sustainable neighborhood design.

To discern general tendency in relatively pure even-aged pine stands, to group the stands and to perceive neighbourhood effects a total of 39 sites of pine stand was surveyed from nearby Seoul (12 sites), Chunsung, Kangwon (13 sites) and Sosan, Chungnam (14 sites), for herb and shrub species 32, 19; 37, 19 and 41, 14 in the respective areas from September 1987 to July 1988. In terms of detrended correspondence analysis (DECORANA), the stands were subjected to ordinate with 16 physical variables and the vegetational variables. The resource ratio (N:P, N:K, P:K) as physical variables also was tried out in the DECORANA as well as independent variable (N.P.K). The outcome did not show any meaningful difference. It is suggested that there seems to be no apparent interaction among the elements in the study. Three vertical vegetation componeent, that is, tree layer, shrub layer, herb layer were subjccted to DECORANA independently, pairwisely and as a whole (a total 7 combinations). Of those analysis herb layer trial alone seems to indicate relatively clearer differences among the physical variables. In the stands nearby Seoul first axis indicated soil field capacity and exchangeable cations (K, Ca and Na) and second axis did not show any tendency. For the Chunsung stands first axis also revealed soil field capcity and amount of arganic matter and second axis showed amount of exchangeable cation (K, Ca and Na), In the Seosan 1st axis indicated pH and exchangeable cations (K, Ca and Na). For the 39 sites 4 clusters in terms of herb layer might be defined: Peucedanum terebinthaceum-Cymbopogon tortilis-Polygala japonica-Festuca ovina (1); Atractylodes japonica-Patrina scabiosaefolia (2); Potentilla fragarioides-Atractylodes (3); and Cymbopogon tortilis (4). In the neighbourhood effects study in terms of the basal area distribution, Thiessen polygon area and Gini coefficient for the Pinus thunbergii stands of Seosan the Thiessen polygon area approach seems to indicate earlier (30 years old) neighbourhood effect than the others (45 years).

This paper presents a multi-objective evolutionary algorithm for combinatorial optimisation and applied for design optimisation of fiber reinforced composite structures. The proposed algorithm closely follows the implementation of Pareto Archive Evolutionary strategy (PAES) proposed in the literature. The modifications suggested include a customized neighbourhood search algorithm in place of mutation operator to improve intensification mechanism and a cross over operator to improve diversification mechanism. Further, an external archive is maintained to collect the historical Pareto optimal solutions. The design constraints are handled in this paper by treating them as additional objectives. Numerical studies have been carried out by solving a hybrid fiber reinforced laminate composite cylindrical shell, stiffened composite cylindrical shell and pressure vessel with varied number of design objectives. The studies presented in this paper clearly indicate that well spread Pareto optimal solutions can be obtained employing the proposed algorithm.

본 논문은 실시간 GPS 항법시스템에서 최단경로 탐색에 일반적으로 적용되고 있는 Dijkstra 알고리즘의 수행 복잡도 $O(n^2)$을 선형인 O(n)으로 단축시킬 수 있는 알고리즘을 제안하였다. Dijkstra 알고리즘은 출발 노드부터 시작하여 모든 노드를 방문하여 최소 경로 길이를 계산한다. 따라서 "노드 수 -1"회를 수행하야 하기 때문에 복잡한 도로로 구성된 도시에서 실시간으로 최단경로 정보를 제공할 수 없는 경우도 발생한다. 제안된 알고리즘은 먼저, 그래프를 트리로, 출발 노드를 근 노드로 치환하여 트리의 각 레벨에 해당하는 외부근방 (Out-Neighbourhood) 노드 집합을 구성하고, 외부근방간과 외부근방 내부의 최소 경로 길이를 계산하는 방법을 적용하였다. 제안된 알고리즘을 양방향과 일방통행로로 구성된 복잡한 2개 그래프에 대해 알고리즘을 적용한 결과 Dijkstra 알고리즘과 동일하게 모든 노드의 최소 경로 길이를 얻는데 성공하였다. 또한, 알고리즘 수행속도를 "노드 수 -1"회에서 "레벨 수 -1"회로 약 4배 정도 단축시키는 효과를 얻었다. 제안된 알고리즘을 GPS 실시간 시스템에 적용하여 러시아워나 차량 사고로 인한 병목현상이 발생하였을 때, 최단 경로 우회 도로 정보를 실시간으로 제공할 수 있다면 운전자의 만족도를 크기 향상시킬 수 있을 것이다.

본 연구는 도심녹지의 대기질 영향을 정량적으로 해석하기 위해 수행되었다. 도심의 '근린공원 녹지'가 가스상 오염물질인 '질소산화물'과 '황산화물'에 미치는 영향을 분석하였으며, 이를 위해 녹지의 대기환경영향평가 모델링시스템이 개발되었다. 모델링은 서울 도심의 대표적 근린공원이라 할 수 있는 종로구의 파고다 공원 인근지역을 대상으로 수행되었다. 모델링 결과, 도시 근린공원의 수목은 자체적으로 오염물질을 흡수 제거하여 대기질을 개선시키는 기능이 크다고는 볼 수 없지만, 상대적으로 친환경적인 토지이용형태(배출원이 거의 없고, 해당지역 및 주변지역에서 원활한 기류소통 촉진)를 유지함으로서 대기환경 악화를 억제하는 효과는 탁월한 것으로 나타났다. 대기오염이 심한 도시지역에서의 대기정책은 오염원 추가건설 제어를 위한 녹지보호정책을 우선적으로 고려해야 할 것으로 판단된다.

The present article is concerned about the study of disturbances in a homogeneous nonlocal magneto-thermoelastic medium under the combined effects of hall current, rotation and two temperatures. The model under assumption has been subjected to normal force. Laplace and Fourier transform have been used for finding the solution to the field equations. The analytical expressions for conductive temperature, stress components, normal current density, transverse current density and displacement components have been obtained in the physical domain using a numerical inversion technique. The effects of hall current and nonlocal parameter on resulting quantities have been depicted graphically. Some particular cases have also been figured out from the current work. The results can be very important for the researchers working in the field of magneto-thermoelastic materials, nonlocal thermoelasticity, geophysics etc.
