The Clarify the distinction of the community structure of the sea birds at Shin Hung fish farm made by sea level and Yong Su reservoir surface level, I investigated above -mentioned thing from January 1987 to December 1987 and have gotten a result like below matters. 1. The sea birds observed at Shin Hung fish farm were 53 species and 1,327 individuals, 45 species, 8,569 individuals at Yong Su reservoir and common species of the two census areas were 34 species. 2. Monthly species number in two areas were there a great deal in May, also passage migrant consisted of various community by visiting in this time. 3. Individual number was the highest in January and February, winter visitor visited in September, October, went in February, April. 4. The most dominant species of two census areas was Anus poecilorhynchu, the following birds were Anus platyrhynchols, Anas cyecca in rwo. 5. Diversity of two census areas was the highest in May, community structure was various and complicated at this time.

A Metadata give a information for contents that describes the attribute of each element a consist of contents model. It is data of data and must describe with a precise indexed label because of more easy to use and find to contents. In this paper, We design and develop the metadata tool that used in the Web, which can create, update and store the essential metadata for LIO learning objects with LOM-based semantic information. It is binded with XML document to support for extensibility and reusability. The tool processes among different distributed computer systems and has max performance in the usability of contents.

We propose a unmaned integrating control system based-on Windows XP version Off-Line Programming System which can simulate a Robot model in 3D Graphics space in this paper. The industrial robot with 4 and 6 axes modeled SM5 and AMI respectively were adopted as an objective model. Forward kinematics, inverse kinematics and robot dynamics modeling were included in the developed off-line program. The interface between users and the off-line programming system in the Windows XP's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by silicon Graphics, Inc. were utilized for 3D Graphics.

The aim of the study is for using the Space Syntax Theory, analyzing the spatial configuration of the traditional area, such as, this study suggest new method of trail plan and purpose of planning the trail in traditional area. For this it was modeling with computer of space configuration on the area of Bukchon and analyzing of the characteristics spatial configuration on the part of urban system and setting of method in the characteristics of spatial configuration with comparison and analysis of the existed trail plan and planning trail on the area of Bukchon.

The equipment of industrial robot in manufacturing and assembly lines has rapidly increased. In order to achieve high productivity and flexibility, it becomes very important to develop the visual feedback control system with Off-Line Programming System(OLPS). We can save much efforts and time in adjusting robots to newly defined workcells by using OLPS. A proposed visual calibration scheme is based on position-based visual feedback. The calibration program firstly generates predicted images of objects in an assumed end-effector position. The process to generate predicted images consists of projection to screen-coordinates, visible range test, and construction of simple silhouette figures. Then, camera images acquired are compared with predicted ones for updating position and orientation data. Computation of error is very simple because the scheme is based on perspective projection, which can be also expanded to experimental results. Computation time can be extremely reduced because the proposed method does not require the precise calculation of tree-dimensional object data and image Jacobian.

In this paper, it is presented a new technique to the design and real-time implementation of fuzzy control system based-on digital signal processors in order to improve the precision and robustness for system of industrial robot. Fuzzy control has emerged as one of the most active and fruitful areas for research in the applications of fuzzy set theory, especially in the real of industrial processes. In this thesis, a self-organizing fuzzy controller for the industrial robot manipulator with a actuator located at the base is studied. A fuzzy logic composed of linguistic conditional statements is employed by defining the relations of input-output variable of the controller, In the synthesis of a FLC, one of the most difficult problems is the determination of linguistic control rules from the human operators. To overcome this difficult, SOFC is proposed for a hierarchical control structure consisting of basic level and high level that modify control rules. The proposed SOFC scheme is simple in structure, fast in computation, and suitable for implementation of real-time control. Performance of the SOFC is illustrated by simulation and experimental results for robot with eight joints.

In this paper, we report some sorts of result obtained by investigating the exhibits which had been submitted for "The National Exhibition of Science"and "The Science Exhibition for the Students of Cheju-do"during the last ten years and by putting the questions to the science teacher of the teacher of the middle and high schools in Cheju-do. Up to the half number the exhibits are occupied by the field of physics and biology. Almost the exhibits (above 90%) have the contents related to those of the current curriculum. However, 30.2% of the respondents only believe that their students may put the exhibits to practical use in learning. Many respondents replied that they could have not participated in the exhibition of science because they were in heavy duty and the fiscal support were not only so limited but also not sufficient enough to make an excellent work.
