In this paper, an algorithm of path planning and obstacle avoidance for mobile robot is proposed. We call the proposed method Random Access Sequence(RAS) method. In the proposed method, a small region is set first and numbers are assigned to its neighbors. By processing assigned numbers all regions are covered and then the path from start to destination is selected by these numbers. The RAS has an advantage of fast planning because of simple operations. This implies that new path selection may be possible within a short time and helps a robot to avoid obstacles in any direction. The algorithm can be applied to unknown environments. When moving obstacles appear, a mobile robot avoids obstacles reactively. then new path is selected by RAS.

Multi-use housing and commercial buildings have been emerged according to social and economic changes of CBD in Seoul Metropolitan Areas. The purpose of this study is to clarify the characteristics of the multi-use building, to analyze the problems on the base of survey and to suggest the solutions for architectural planning, focusing on eco-friendly dwelling environment. A field survey with 46 subjects has been carried out with structured questionnaire. Some problems in planning of the complex building have been discussed in terms of environmental issues and design criteria. In conclusion, basic planning directions for improving the building environmental quality have been suggested.

A rule-based CAPP(computer aided process planning) system is proposed in this research to develop integrated manufacturing process of machining and inspection using OMM(On-Machine Measurement) device. Generally workpiece composed of many primitive form features. This features are determined optimum inspection sequence by analyzing the feature information such as features-relationship, probe approach direction and etc. Proposed paper is more efficient method of CAIP(computer aided inspection planning) considered machining process

The purpose of this study is to accumulate basic data to establish planning direction of the environment-friendly remodeling through residents' consciousness in apartment Housing. The results are as follows : 1)More than half of residents thought remodeling is influential in decreasing of environmental pollution. 2) The important planning factors of the environment-friendly remodeling appear saving-energy, increasing health & amenity, coping with the change of population & society.

A global path planning algorithm using modified self-organizing feature map(SOFM) which is a method among a number of neural network is presented. The SOFM uses a randomized small valued initial weight vectors, selects the neuron whose weight vector best matches input as the winning neuron, and trains the weight vectors such that neurons within the activity bubble are move toward the input vector. On the other hand, the modified method in this research uses a predetermined initial weight vectors of the 2-dimensional mesh, gives the systematic input vector whose position best matches obstacles, and trains the weight vectors such that neurons within the activity bubble are move toward the opposite direction of input vector. According to simulation results one can conclude that the modified neural network is useful tool for the global path planning problem of a mobile robot.

Considerable research has concentrated on medium-range production planning model in that it can contain long and short-term decision making in contents. Since medium-range production planning deals in situations with setup time or/and costs, solution methodology is classified by (1) optimization method using a sort of integer programming approach and network formulation (2) heuristic method offering an computationally easy, approximate solution. But, solution methodology is different in type of demand generation, existence of capacity and dependant demand. Therefore this paper reviewed the medium range production planning according to above mentioned three factors, and suggested for further work direction.

The awareness of ecological friendliness has been emerging in the recent years, and the application to housing is quite notable. The purpose of this study is to evaluate environment-friendly planning factor in Environment-friendly Housing Certification. For this purpose, this study has analyzed 5 multi-family housing in Environment-friendly Housing Certification. The findings of this study are as follows: The application of environment-friendly planning factor in interior space are limited. Most of plans are located in south. The variability of floor plan is not applied but the built-in storage is well-applied. Environment-friendly finishing material and the garden-style balconies was applied in a passive way. This analysis showed current status of planning factor of unit apartment in Environment-friendly Housing Certification and proved basic information for future direction.

This study aims to find out the way of revitalizing of natural riverfront space in terms of ecological aspect. At the first part, theoretical made in terms of concept, planning aspects and techniques which were main bases for the study. It begins by explaining the concept of ecological riverfront space, the main aspect and techniques of its planning. After this, it analysis eight cases(four cases in Korea, Swiss, Germany, America and Japan) in terms of the objects, planning techniques and the results of development. It continues by making detailed analysis according to four objectives like 'protection from flood', 'quality of the river', 'ecological preservation' and 'active usage of riverfront space'. It ends by evaluating the relationship between objectives and the planning which will be adapted to the future development of riverfront space with ecological aspect. In conclusion, hereafter will propose desirable design-direction for revitalization about riverfront space about ecological aspect design in urban.

This study demonstrates a basic concept and designing direction for the realisation of disaster prevention planning in u-City(u-BangjaeCity) that is from establishing a planning system in terms of the areas of professional disaster and safety management for the national disaster management. and designing disaster or safety management system via using ubiquitous technology for the scientific disaster management. In order to realise u-City it is necessary to maps out interrelation amongst various services such as traffic, environment and disaster prevention. Domestic and international case studies regarding the tendency of disaster prevention planing in u-City and its analysis could be the fundamental resource in order to develop the standard model of u-BangjaeCity.

In this paper, the continuous motion of a quadrupedal walking machine was studied. The motion planning which is able a walking machine body to precisely follow a three-dimensional curve was developed. A three-dimensional curve was designed based on Bezier curve and obstacle avoidance considerations. Due to the arbitrary motion direction during walking, special strategies of gaits were developed to ensure positive stability. The gait strategies were based on wave and wave-crab gait.
