사료조관리의 목적은 신선하고 기호성이 좋으며 영양적으로 균형잡힌 사료를 젖소에게 급여하므로써 건물 섭취량을 최대화 시키려고 하는 것이 아닌 적절하게 섭취할 수 있도록 유도하여 유생산성을 안정적으로 유지하고 우군의 성적을 최적화 하는 것이다.

This paper suggests the method for saving the digital map which was made through aerial photography to ORDBMS (Object Relational Database Management System) and analyze its efficiency through experiments. The digital map has been used by file units because of managing or providing it to others. But this way can not get sequential graphic entities and just use it which was included in only one map. In this paper, we saved the digital map to ORDBMS at a time after converted the digital map entities based on the tile to the things can be inserted to ORDBMS. And, we also proved the possible methods to extract the graphic entities what we need from entire blueprint through experiments.

In this paper, we propose a fast collision detection method for interacting with objects in virtual space. First, in the mesh grouping step, the entire space is divided into small spaces of a predetermined size, and the positions and sizes of the smallest basic stereoscopic shapes (cube or sphere) including all of the meshes belonging to each small space are determined. In the collision detection step, it is checked whether a haptic interface point (HIP) is included in a three-dimensional figure representing a group. When a collision with a specific three-dimensional figure is confirmed, searching is performed only for the meshes in the group to find a mesh on which a possible real collision with HIP occurred. The effectiveness of the proposed algorithm is verified by measuring and comparing the computation time of the proposed method with and without the proposed method.

We studied what kind of science-contents problems can also give information on one's creativity for use in the selection of scientifically gifted. 383 7th and 8th graders as subjects, we first analyzed the corelation between the results of creative thinking, scientific attitude, science inquiry, logical thinking and the scientific creativity problem solving skill test. The corelation analysis indicated that science inquiry test could represent other tests except TTCT. We then tested 532 6th graders with TTCT and science inquiry tests concomitantly with the contents- related problems made in such types as naming 20 scientists, writing about a scientist, imagination to overcome a problem, understanding of theory and application and understanding of science laws and application. The results indicated that writing and imagination were most efficient in assessing both the contents and the creativity.
