Despite the many significant advances made in robot architecture, the basic approaches are deliberative and reactive methods. They are quite different in recognizing outer environment and inner operating mechanism. For this reason, they have almost opposite characteristics. Later, researchers integrate these two approaches into hybrid architecture. In such architecture, Reactive module also called low-level motion control module have advantage in real-time reacting and sensing outer environment; Deliberative module also called high-level task planning module is good at planning task using world knowledge, reasoning and intelligent computing. This paper presents a framework of the integrated planning and control for mobile robot navigation. Unlike the existing hybrid architecture, it learns topological map from the world map by using MST (Minimum Spanning Tree)-based SOFM (Self-Organizing Feature Map) algorithm. High-level planning module plans simple tasks to low-level control module and low-level control module feedbacks the environment information to high-level planning module. This method allows for a tight integration between high-level and low-level modules, which provide real-time performance and strong adaptability and reactivity to outer environment and its unforeseen changes. This proposed framework is verified by simulation.

Even if Korea has established various legal guidelines as well as plans for the purpose of systematic management of urban citycapes, various problems have been pointed out, such as a decrease in operational efficiency because the legal framework is not clearly defined and the guidelines do not fully reflect regional characteristics. In the midst of this, Singapore is being mentioned as a representative example of enhancing international competitiveness by forming an outstanding urban cityscape through successful urban planning and operating system. Therefore, this study aims to suggest a direction for the improvement of Korea's urban planning and design guidelines by investigating and analyzing the characteristics of Singapore's urban planning system and design guidelines. As a result of the research and analysis, it was concluded that Singapore's urban planning system was based on the unified planning and management system. In particular, the Singapore Urban Design Guidelines provide differentiated guidelines to maintain and strengthen regional characteristics based on linkage with higher-level plans as detailed practical guidelines, and were operated as flexible guidelines reflecting the changes of the times and the needs of members of society. It also provides a direction for the improvement of the Korean urban design system, such as to increase the executionablity of the plan and the efficiency of operation by utilizing various guidance and support policies, rational and simplified deliberation procedures, and allow a platform that enhances the accessibility and convenience of related information.

This study deals with the derivative adverse minimum for inferiority system depends on continuose operating under infinite planning horizon. This planning will be accomplished by maintenance limit renewal policy in consideration of opportunity cost which affects system by failure during operation periods and expected cost under nomal operation states. By the results, we will be expected incresing total efficiency for the system by optimal renewal policy.

A mathematical model for long-rage water supply planning was formulated as a dynamic plant location problem with network arc capacity expansion, and illustative example was presented. The proposed solution procedure identifies economical construction timings of surface water supply facilities and water conveyence systems and the best water supply operating patterns as well. In this study, we present a heuristic solution procedure using Simulated annealing Method in conjunction with Bertsekas & Tseng's RELAXT-II for the 0-1 integer network problem.

This study provide the planning guidelines for the existing and the new alternative. On the bases of survey and analysis, the basic data for OP-Unit have been proposed in consideration of the development of medical science and hygiene, economic conditions during the last twenty years in Germany. The results of the study were firstly, genera1 basic data, secondly, guidelines of the architectural design for OP-Unit und rooms, thirdly, new alternative OP-Unit with 2 and 3 operation rooms.

The space planning and interior layout of recovery unit should be determined carefully for patient's nursing and observation which is considered to prevent infection and to cope quickly with emergency situation after surgical operation. Recently, the recovery unit in medical facilities is planned and managed without consideration of operating system, sanitary facilities and prior condition of space. Therefore, there is required to the logical criterion of architectural planning for patient's recovery unit which is concerned about opinion of medical team, anesthetist, sanitarian, architect and patient as a user. As the result, this study would apply to design guideline for the architectural planning of patient's recovery unit.

Recently the number of rural development plans are increased and projects supported by government are various. These makes rural plans important. But there are many gaps between proposed plan and implementation. These gaps were wasteful in terms of resource management. This study examines differences between plan and implementation and the reasons why they are occurred. For this purpose, we did a case study which is focused on the four-year implementation of 2004-2006 "Unique Experience Village Master Plan" of Seochon, Chungbuk. As a result, we verified facts of gaps and causes, and two major causes were detected : one is the absence of operating and managing body(such as promoter of project, village leader, residences), and the other is inadequate master plan.

Many vehicle routing methods have been suggested, which minimize the routing distances of vehicles to reduce the total transportation cost. But the more considerations the method takes, the higher complexites are involved in a large number of practical situations. The purpose of this paper is to develop a vehicle distribution planning system using heuristic algorithms and simulation techniques for home electronics companies. The vehicle distribution planning system developed by this study involves such complicated and stochastic conditions as one depot, multiple nodes(demand points), multiple vehicle types, multiple order items, and other many restrictions for operating vehicles. The proposed system is compared with the nearest neighbor method of the current system in terms of total logistics cost and driving time. This heuristics algorithm and simulation based distribution planning system is efficient in computational complexity, and give improved solutions with respect to the cost as well as the time. This method constructs a route with a minimum number of vehicles for a given demand.

This study is to find out vitalization plan of rural village festival through field survey and in-depth interview. Festival vitalization plans were suggested for each of four steps. The results are as follows: (1) preparing stage : disambiguation of supporting festival, adjustment of selecting times & improvement of selecting index in supporting festival, support of planning & managing ability, and systematization of festival consulting team. (2) planning stage : supporting differentiated festival program development, and public relations of rural village festival. (3) operating stage : flexible utilization of supporting budget and systematization of festival supporters operation. (4) ending stage : holding a workshop to share successful festival cases.

This study discusses how to rationalize or innovate the managerial practice of the profitability-deteriorated hospitals in Korea, and attempts to suggest proper planning models and strategies to reorient them. For these purposes, the hospitals' financial indicators were analysed, the process of profit planning were reviewed, and strategic assessment were made, using relevant data. The analysis shows that failures both in proper capital investment to fixed assests and in effective containment of operating costs have been causing the worsening of profitability. For the improvement of the profitability management, seven procedural and behavioral strategies were suggested from the innovative and rationalizing perspectives, together with necessary prerequisite conditions to be equipped with for their implementation. This study concludes that the top management should attempt the changs on their own initiative.
