鴻農映二 서경대학교 1982 論文集 Vol.10 No.-
This treatise is about Kim-So-Wol the Korean poet. Kim-So-Wol was born sept. 1902. in Pyonpuk, When he was two years old his father was attacked by a group of railway workers. his father got mad his mother was a very strict woman so So-Wol did not enioy mother's love and so his personality was marked bylonliness. He graduared from. Namsan elementary school, then Pege senior high school and Finally Tokyo university of comencem. He established Abranch of the newspaper Dogne-A-Ilbo But he was jaited for his nenvoties so he killed himself DEC. 12 1932. now we can see his many literary works, and that of many reviews. But we can never see the reviews of his literary works in Japanese. Kim-So-Wol write a few poems in Japanese. this tact indicates that he was infurenced by the Japanese. We can divide his poems into three forms in Japanese. Ⅰ. poem with a definite form Ⅱ. poem with a non definite form Ⅲ. Ⅲ is between, Ⅰ and Ⅱ, form Ⅰ is 7·5 rhythm. but this is not perfect. because So-Wols form is of the following style. 6·5·7·5 6·4·7·5 6·4·7·5 6·5·7·5 (ex.1) 7·5 6·5 7·5 6·5 (ex.2) We can see the difference between So-Wol s art and Japanese poems. and We can think that this difference is based on the way of the thought of the Korean poet, Shi-Jo. form Ⅱ is reflects despair and this tendency is also found in his crihcal essays. form Ⅲ appears to be one aspect of protest form Ⅰ includes two poems. form Ⅱ has four poems, and form Ⅲ has one. There are not many poems of his writter in Japanese. But now we can appreciate his ability as a poet through these poems. Because he has shown consideradle ability writing Peems in Japanese.

In this study, voxel model representation is applied for a geometric machining shape simulator. A voxel model generally requires a huge amount of memory for shape representation, therefore the multilayer Octree structure of voxels is utilized to reduce the memory usage and improve the accuracy for the complicated shape representation of three-dimensional objects. Based on actual tool paths, case studies of machining shape simulation were carried out to examine the relation between the Octree layer levels with calculation time and memory usage. Furthermore, the ability to simulate machining shapes for both 3-axis and 5-axis milling operation were verified.

Photovoltaic generation systems need MPPT (Maximum Power Point Tracking) control because the output power depends on the operating voltage and current. Therefore, many researchers propose various types of MPPT control methods. A new MPPT control scheme is proposed in this paper in order to realize higher efficiency with simple calculation. The line search algorithm with flbonacci sequence which is one of the optimizing method is employed for the MPPT. The line search method is modified for real-time operation. The method is verified by simulations and experiments. It is concluded that the scheme can respond fast variation of irradiance.<br/>
