The purpose of this study is to provide the guideline of the outdoor space of residential land development district for children's outdoor activites. This study was accomplished by the valuation of the physical environment of 5 residential land development districts, the analyzation of behavioral mapping about children's outdoor activities, and the analyzation of satisfaction and the consciousness of 190 residents(parents) & 230 children. Especially, outdoor spaces were divided into 6 parts (play space, education facility, commercial facility, green space, and empty space & parking lot). And than, 6 outdoor spaces were valuated about the physical characters such as accessibility, network, safety, variety, functional, natural elements. Also, the survey for residents and children's consciousness were used the Likert scale. According to the result of this study, many parts of the housing area were not good for children's activities, and resident's satisfaction was low. In the sample areas, negative factors were car and motorcycle. And many residents were pointed out the lack of natural elements, variety, and safety of outdoor space in dwelling area. Finally, this study suggested the guideline children's activities based on the result of analyzation of valuation, behavioral mapping, and survey.

The propose of this study is to suggest objective data to be utilized for a plan and the improvement of open space through the analysis of people's behaviour and satisfaction after the introduction of an opened-fence around offices followed by a plan for wall-afforestation of public institution's. The sites examined are four offices; two of them have opened-walls and the others have traditional enclosure. Analysis of frequency is conducted to understand the actual use according to people's individual peculiarities. Pearson's correlation analysis, t-test, multiple regression analysis are carried out to find out relations of fluents. In the end, the satisfaction is high in public institution satisfaction, entrance, space perception. stability, Landscaped office with opened-fence rather than fence, and the increase in usage of fluent of public institution satisfaction, entrance, space perception. stability, confusion brings about rising of use-satisfaction. Satisfaction with the exterior of building is the most important variable that influences the whole urban open space. Furthermore the influences of the approach and stability having connection with open or not-open fence is major variable affecting satisfaction of use of open space. Whether open or not is important factor on satisfaction of open space of office building. Through this study, we can find that opened fence determines use satisfaction of resting space of outdoor-office. So factors affecting satisfaction must be regarded as important requisite on planning, design, development and management in plan for afforestation of fence at public institution.

In this paper, the authors introduced a new approach to find the optimal collision avoidance maneuver considering multi threatening objects within short period, while satisfying constraints on the fuel limit and the acceptable collision probability. A preliminary effort in applying a genetic algorithm (GA) to those kinds of problems has also been demonstrated through a simulation study with a simple case problem and various fitness functions. And then, GA is applied to the complex case problem including multi-threatening objects. Two distinct collision avoidance maneuvers are dealt with: the first is in-track direction of collision avoidance maneuver. The second considers radial, in-track, cross-track direction maneuver. The results show that the first case violates the collision probability threshold, while the second case does not violate the threshold with satisfaction of all conditions. Various factors for analyzing and planning the optimal collision avoidance maneuver are also presented.

This paper analyses connecting space of the 'ㅁ' shaped houses from Chosun Dynasty, Korea. Houses are reflected by various factors such as shapes, locations and territoriality by the social class system. Because of their spatial arrangements, 'ㅁ' shaped houses might have various planning approaches. This paper looks at Sarang-chae and An-chae, which are the common elements of the houses, and analyses their architectural characteristics in spatial arrangements and territoriality. The territoriality was formed by the combination of Chae and Madang. The spatial arrangement was formed by the social norms of its time. Hengrang-chae and Dam-jang, which were located in-between Chae and Madang, limit territoriality by providing privacy and interrupting the circulation.

This study intends to establish a system to investigate and analyze various impacting factors to Rural Housings such as the relationship of characteristics of Rural Housings located in a Rural Village to the Village and a Unit Housing, to the External and Internal Spaces inside the Unit Housing and the Village, and to Living Characteristics of the Residents and Space from an integrated point of view. The results of this study are largely summarized as following four kinds. Rural Housing Survey System can be largely classified into three stages, and they are a Preliminary Survey, Basic Survey and In-depth Survey. Along with these, the scope of the survey contents can be divided into a survey result by a unit of village, of land, of housing, and of resident's opinion survey. Secondly, the surveys by village unit are on location properties, Village Identity, Street Network, Land Use, Landscape Features and Public Facilities, and consist of Literature, Discussion and Field Survey. Thirdly, the land Unit Surveys are on a Driveway, Gate Location, Housing Placement, Outer Space Design in a Yard and Outer Space Use Characteristics, and consist of Questionnaire and Field Surveys. For the fourth, the Housing Unit Surveys are on an Internal Space Design and Placement, and consist of Questionnaire and Field Surveys. Finally, the Resident Questionnaire Survey consisted of Entire Discussion Survey and a Household one, and then the Entire Survey was on the Village's History, Village's Characteristics, Cultivation Characteristics and Community Activities while an individual one was on Main Living Characteristics, Satisfaction and Utilization Characteristics.

The purpose of this study is to extract landscape design elements regulation of the District Unit Plan(DUP) in new town areas, and to find out characteristics in terms of urban design elements in comparison with the psychological and physical aspects. For this purpose, we reviewed urban design elements and design elements in terms of the landscape by DUP and analyzed the activation of landscape on the selected case-area by interviewing experts such as planners, public officials, and professors in the department of urban planning and landscape, as well as the university students. The analysis framework for the case-study consists of 4 components: the section of region, street, building, open space, etc. The new development areas in Daejeon Metropolitan City was chosen as the case study area, because they have been developed by DUP regulations. As a result of this study, we can extract characteristics of landscape. The results indicate that `skyline design',`view corridor design',`landscape design',`street furniture design' and `building design(form, height, color, and elevation)' are the key planning and design factors influencing differences in the landscape preference. This research identifies that there are no detailed planning and design guidelines adopted within the four case study areas in Daejeon for regulating the characteristics of skyline, planting and street furniture while detailed guidelines established for density, building height and site layout. Considering their significant correlation with the level of landscape preference, this study suggests that detailed planning and design guidelines for the characteristics of skyline, rooftop and streetscape should be established in future DUP.

The purpose of this study is to provide the basic data for planning and designing Village Parks in Seoul in the future, which result from analyzing post-occupancy evaluation. For conducting this study, 10 Village Parks among 45, built between 1996 and 1997, were selected and analyzed. The results of this study are as follows. The degree of satisfaction of 10 Village Parks in Seoul has been evaluated on a scale of 10, to be a 6.68 average. This result means that the most respondents are satisfied with the existing Village Parks in Seoul. The correlation of the degree of satisfaction with major planning factors for 3 types of Village Parks shows that accessibility is the most important factor. As for future directions of planning and designing Village Parks, many kinds of sitting, leaning and resting place need to be provided. It is also necessary to improve the visual quality of the parks with various spatial elements. The research also shows that various facilities for people's use should be provided in Village Parks.

The nature is the foundation of human life and arts, and human beings have found order and principle amid ceaseless change and harmonization of the nature and diversified patterns and directly or indirectly applied the nature to interior through discovered principles. Interior space to which the organic factors of the nature is an expression of the vitality of the nature and expresses live forms as seen in change, development and growth of living organisms in addition to human feelings. The study aims to recognize the necessity of studies on interior space to which organic expressive characteristics of the nature are applied in uniformed space, suggest expressive characteristics and propose needed basic data required at a time of designing interior space. In this regard, the study has examined works by five contemporary designers including Zaha Hadid, Karim Rashid, Fabio Novembre and Nox with an aim to analyze expressive characteristics of interior design and figure expressive characteristics of organic design found in interior space. According to analyses on preceding literary studies and case studies (14 places), it has been found that organic expressive characteristics in interior space include vision, tactile sensation and auditory sense in terms of sensitivity, immateriality in terms of a property of matter, metaphor and abstraction in terms of the form of natural objects and non-linear curves and free curves in organic design. Organic spaces were characterized by symbolism, directionality, continuity, pattern and superimposition. This conclusion is expected to be useful in subsequent studies on the application of organic expressive characteristic factors at a time of planning interior space in the future.

The purpose of this study is not only to compare between 'Opened Landscape' and 'Filtered Landscape' image and preference but also to suggests a guide line of planting design for progressive realization. For this, the image structures of photo-sketch simulation for parallax landscape have been investigated by Semantic Differential scale(S.D. scale) and the Factor analysis. The results could be summarized as follows. The results of S.D. scale values for landscape through parallax were greater than non-parallax landscape. The scenes through parallax were better preferred to direct view. Thus the results of photo-sketch simulation test support the expected hypothesis that the visual environment of complexity and variety is closely correlated with the parallax effect and monotonous or non-parallax environment, and parallax effect on close view more bigger than the distant view. Factors covering the spatial image of parallax landscape were found to be seven and Total values were 60.35 %. The most important factors determining the parallax effect were Factors I 'depth of space' and VI 'expectation of space and interest'. An outstanding view must be handled properly to be preserved or accentuated. In this sense, the parallax spatial beauty with tree could be improved through the visual aspects of plan arrangements and the progressive realization appeared to be one effective design technique for landscape planning and design.

For the vast majority of geostationary satellites currently in orbit, station keeping activities including orbit determination and maneuver planning and execution are ground-directed and dependent on the availability of ground-based satellite control personnel and facilities. However, a requirement linked to satellite autonomy and survivability in cases of interrupted ground support is often one of the stipulated provisions on the satellite platform design. It is especially important for a geostationary military-purposed satellite to remain within its designated orbital window, in order to provide reliable uninterrupted telecommunications services, in the absence of ground-based resources due to warfare or other disasters. In this paper we investigate factors affecting the robustness of a geostationary satellite's orbit in terms of the maximum duration the satellite's station keeping window can be maintained without ground intervention. By comparing simulations of orbit evolution, given different initial conditions and operations strategies, a variation of parameters study has been performed and we have analyzed which factors the duration is most sensitive to. This also provides valuable insights into which factors may be worth controlling by a military or civilian geostationary satellite operator. Our simulations show that the most beneficial factor for maximizing the time a satellite will remain in the station keeping window is the operational practice of pre-emptively loading East-West station keeping maneuvers for automatic execution on board the satellite should ground control capability be lost. The second most beneficial factor is using short station keeping maneuver cycle durations.
