The objective of this study is to provide direction for agricultural extension services in an age of localization. Agricultural extension services has carried out most of its activities by central direction and control. The central planning and management resulted in disappointment, inflexibility, and lack of responsiveness of the central bureaucracy. Facing localization in recent years, the extension system has not been satisfactorily developed to meet local demands. Korea has to choose to decentralize its extension services. The decentralization of extension services involves the transfer of planning, decision making, and management from the central government to the local level.

Establishing public kindergarten is very important in social welfare aspects. So far almost public kindergarten were built up as attached style in primary school. More independent style kindergarten is being requested for small land area, shorter commuting distance. But the standard design guideline of the independent public kindergarten is insufficient. The purpose of this study is to examine the architectural Planning direction for the standard design guideline of the independent public kindergarten. A result of this study can be suggested what kind of architectural Planning direction of independent public kindergarten is needed more acutely.

This paper deals with the trajectory planning of multi agent robots using complex potential theory for robot soccer. The complex potential theory is introduced, then the circle theorem is used to avoid obstacles, and the vortex pair is used to make precise kicking direction of robot. Various situations of robot soccer are simulated and the effect of vortex strength and the speed of robots are discussed and the better way to avoid obstacles and to kick the precise direction is found. The feasibilities of complex potential theory to apply for the multi agent robots are successful.

R&D association is a very important institution to promote inter-firm technological cooperation, In Korea, they have begun to be established in 1982, and at now 56 R&D associations are working. The purpose of this study is In analyze the problems of the R&D associations, and to suggest a new direction of their future development Their problems were analyzed from the perspective of cooperative R&D mechanisms, especially with a new concept of R&D community : search community, planning community, community of research itself. This study emphases the importance of the R&D association's role as a planning community, and the institutional linkage between R&D association and National R&D program through the introduction of design-in planning system.

Community is on the group of people who live in same area and share same life style. The purpose of this study is to suggest Improvement of the Community Facilities for the Community activation and Management in Public Rental Housing. It focuses on the planning methods through observation and survey with residents of Public Rental Housing. The result of the study are summarized as follows: Frist, the community demand will increase significantly in the near future for development of Public Rental Housing. Thus, it should be accomplished by Preparing Practical Planning direction, Second, this study suggest that improvement direction for system, planning and application of the Community Facilities for the Community activation and Management in Public Rental Housing.

This paper addresses the vision based autonomous walking control system. To handle the obstacles which exist beyond the field of view(FOV), we used the 3d panoramic depth image. Moreover, to decide the avoidance direction and walking motion of a humanoid robot for the obstacle avoidance by itself, we proposed the vision based path planning using 3d panoramic depth image. In the vision based path planning, the path and walking motion are decided under environment condition such as the size of obstacle and available avoidance space. The vision based path planning is applied to a humanoid robot, URIA. The results from these evaluations show that the proposed method can be effectively applied to decide the avoidance direction and the walking motion of a practical humanoid robot.

It is well known that urban environment affects climate, as we can see in the quality of bio-climate. However, climate has not been recognised properly in the urban planning process. The role it flays needs to be examined for better urban environment. The main objective of this study is to investigate the climate-ecological priority area which produces cold fresh air and thermal induced wind circulation between rural and urban areas. The objective is also to improve the quality of bio-climate and wind circulation at blocked urban areas. This paper uses the measurement and analysis method of wind direction and wind speed in order to investigate the climate-ecological priority area and cold fresh air corridor. In this study, local climate conditions i.e. wind speed, wind direction, temperature, humidity etc., were measured at nine fields and analyzed. On the basis of the climate measurement, the climate ecological priority areas were delineated; These will be assigned as climate-ecological conservation areas.

This study focuses on the impacts of apartment building arrangements on the outdoor and indoor air quality - the efficiency of natural ventilation in the outside/inside area of an apartment with consideration to the characteristics of an air flow in outside area depending on the types of the arrangements, the main direction of the wind, and the outside wind pressure on the building facade. As indices to evaluate the efficiency of natural ventilation, the concepts of "Age of Air" and "Purging Flow Rate(PFR)" were used in this study. As indices to classify the efficiency of indoor natural ventilation, the mean values of the wind pressure differences between the front and the back elevations of an apartment building were used. The research showed that the PFR of each apartment building arrangement ranges from 0.867 to 3.253. The "minus-shaped" arrangement showed the highest PFR, 2.306; the "zigzag-shaped" arrangement measured 1.889; the "angle-shaped" arrangement measured 1.465, and the "square-shaped" arrangement measured 1.241. Depending on the direction of the wind, the pressure differences range extremely, with variations from 170% to 2300%. Thus, the indoor natural ventilation efficiency can be changed by the pressure differences of the wind, which are sensitive to the main direction of the wind even though the structure and planning of the apartment complexes are the same. Despite the same direction of the wind, even the efficiency can be diverse. This study showed how to predict the most beneficial apartment building arrangement for the profitable natural ventilation efficiency in each direction of the wind.

The purpose of this study is to examine exposure and direction in slope as well as entrance of site in order to research the site planning of the dwellings in Hahoe Village. In this study, the survey data during seventeen month from April 1998 to August 1999 was measured and analyzed. The result of this study were as follows ; 1) The rate of exposure and direction in slope as well as entrance of site was find out in order of the south(30~38%).east(22~28%).north(21~24%).west(14~22%) aspect. Among others, exposure was most due south.southeast.southwest aspect. 2) The interrelation of exposure and direction in slope as well as entrance of site was find out high within the limits of general visible.

A feature is a local shape of a product directly related to the manufacturing process. The feature plays a role of the bridge connecting CAD and CAM. In the process planning for he CAM, information on manufacturing is required. To get the a manufacturing information from CAD dat, we need to recognize features. Once features are recognized, they are used as an input for the process planning. In this paper, we thoroughly investigate the composite features, which are generated by interacting simple features. The simple features in the composite feature usually have precedence relation in terms of process sequence. Based on the reason for the precedence relation, we classify the composite features for the process planning. In addition to the precedence relation, approach direction is used as an input for the process planning. In the process planning, the number of set-up orientations are minimized whole process sequence for the features are generated. We propose a process planning algorithm based on the topological sort and breadth-first search of graphs. The algorithn is verified using sample products.
