This paper presents the integration of occupancy grid mapping and path planning for navigation of a mobile robot in unknown environment with binocular stereo vision as an only sensor. Since the visual information for building occupancy grid map in real time is noisy, a modified simple map updating algorithm is proposed. The proposed algorithm provides fast and reliable results. And we also propose real-time robot direction decision algorithms in path planning. The algorithms provide appropriate responses to unanticipated real world events when it is used with A* search algorithm. Experimental results show that the proposed algorithms are effective and well-designed for autonomous navigation with stereo vision system.

Objectives The purpose of this study was to survey the status of clinical use of a computerized tongue diagnosis system (CTDS) Methods We searched domestic/international articles using the CTDS from online medical databases including OASIS, NDSL and pubmed. We selected articles on clinical application or reliability of CTDS but excluded articles on mechanical design or software programming for developing a new CTDS. Finally we found 15 articles and classified the articles according to the study purpose. Results Out of the 15 articles, 8 were focused on the clinical application including halitosis, cold/heat syndrome, lung cancer, xerostomia etc. Other 5 articles were aimed at evaluating and improving reliability of CTDS. The other 2 articles were studied for development of differential diagnostic criteria on tongue coating thickness. Conclusion We found out that until now the researches on clinical application of CTDS mainly had been performed for producing a variety of CTDSs. Considering the importance of the tongue color in the traditional Korean medicine, we suggest that at first standard operating procedure for CTDS be developed and researches to develop differential diagnostic criteria on tongue body/coating color be performed and then explore its applications.

The purpose of this study is to investigate the policy of Physical Education, Administration System and School Physical Education in Canada which is the sports country of the developed country, and thus to suggest the development directions of School Physical Education and the Sports in Korea. As the results of this study, we acquire the following conclusions. 1. We make use of the topographical conditions of Korea and then must execute the Physical Education and Sports Program in Korea. 2. It is desirable which the National-Wide Sports Event is opened once 2 years. 3. The National Enviroment which enjoys the Sports on weekends must be expanded. 4. We clearly divide the authorities of Elite Sports and Living Sports, and then must make develop it. 5. We must make many women to take part in the sports. 6. The activities of Recreation Associations must be activated. 7. The physical education of Middle & High School must be actualized as soon as possible. 8. The role of the schoolmaster in the program of the School Physical Education must be expanded.
