1897년 적리의 병균을 세계 최초로 발견해 명성을 떨친 일본의 세균학자 시가 키요시는 1920년부터 11여년간 한국에 근무하면서 조선총독부 의원장을 거쳐 경성제국대학 총장을 역임했다. 이러한 사실은 그의 고향인 센다이시의 한 공원의 흉상에 새겨진 이력 소개문에서 우연히 발견한 것으로 우리나라의 의료사에도 그의 이름이 나오지 않는다. 1896년 동경대를 졸업한 다음해 적리균을 발견해 28세때 세계적인 학자로 발돋움한 시가 키요시의 생애를 조명해 본다.

The aim of this study is to review the improvement method of Korea capital gains tax according to the alienation of the real estate, and to suggest an improvement plan. The study has been carried out by reviewing the related literatures. Capital gains tax could be calculated either using the actual price of sale or the standard prices. Korea capital gains tax has been revised many times since 1975 when it was first enacted. Initially the actual price of sale was the default rule and the standard prices was allowed only exceptionally if the actual price of sale could not be detected. The actual price of sale rather than the standard prices should be used for determining the capital gains tax on the transfer. By doing so, the desired principles of taxation such as "principle of taxation on tax paying ability". In conclusion, the present capital gains tax of Korea should be improved in many aspects in order to promote income redistribution function and efficient allocation of resources.

In this study, total astigmatism and corneal astigmatism were studied 328 eyes of healthy Korean for astigmatism. Total astigmatism was measured by fogging-and-dial technique, and corneal astigmatism was measured with Topcon OM-4 keratometer. Residual astigmatism was determined by a discrepancy between total and corneal astigmatism. The results were as follows: As they aged, there were a statistically significant changes in total and corneal astigmatism but not in residual astigmatism. And the amount of with-the-rule total and corneal astigmatism had a tendency to decrease, but residual astigmatism had no changes. From 30 years, total astigmatism showed a tendency to become against the rule. The average diopteric value was +0.342D in total astigmatism. +0.920D in corneal astigmatism and -0.579D in residual astigmatism.

In action games such as shooting games or platform games, dodging enemy objects is crucial since the player character dies or loses energy when it collides with any enemy object. In this paper, we investigates how the difficulty of these games changes according to the existence of salient objects. Since salient objects attract the player's attention, other non-salient objects may be unattended by the player, resulting in failing to dodge them. We experimented on the influence of salient objects on the difficulty of a game, and found out that the subjects who played the game without salient objects performed better than the subjects who played the game with salient objects. This paper investigates a human perceptual issue that could affect the game difficulty and suggest a potential guideline for game design and planning.

Gugok poems were an important material for studying the Gugok landscape garden(九曲園林). the landscape feature(景物)that emerges from poetry is an important material that expresses the sense of placefulness and garden consciousness(園林意識). However, many studies are passive about plant materials that can explore the perception of nature or the aesthetic embodiment process. Therefore, this study seeks to discover various symbolic meanings and reveal the context of plants that have appeared in Gugok poems in order to expand the research material of the Gugok culture. To carry out the purpose of the study, I collected a total of 25 related poems from 18 Gugoks and found a total of 20 species of trees. I used 'R-program' to derive the meaning of trees and examined the meaning of trees by intertextuality. According to the study, the 20 species of trees contained symbolic meanings of world of Taoist hermit, pursuit of study, constancy, true pleasure, dignity, honest poverty, reign of peace, nostalgia. Many species focused on the symbolism of the 'world of Taoist hermit' and then on the 'dignity' was the most frequent. A number of species, except for the peach, zelkova and oak, had multiple meanings. Among them, pine trees and lotus had a wide range of symbolic meanings and different meanings depending on the characteristics of the surrounding landscape. While the Gugok culture generally targets natural scenery, Yongsan, Toegye, Deoksan, and Jusan showed the characteristics of strengthening or reproducing symbolic meanings through artificial plating and gardening. In order to overcome the limitations of the peach tree, which symbolizes 'Mureungdowon(武陵桃園)', Gugok poems used maple trees and reeds as alternative species. In accordance with the above context, the trees appearing in the Gugok poems expressed their symbolic meaning differently according to the landscape features, acts and purposes of the Gugoks, rather than sticking to the traditional meaning.

The for this study, turning circle tests and maneuvering indices were conducted to study and evaluate the maneuverabilities of the fishery training ship M.S. A-RA(G/T : 990tons). The results obtained were summarized as follows : 1. The advances of the starboard and port of the turning circle were measured based on the dumb card test method were 198m, 192m, the size of tactical diameters of them were 194m, 188m, respectively. 2. The advances at the starboard and port of the turning circles were measured according to the DGPS positioning obtained 196m, 194m, the size of tactical diameters of them were 194m, 190m, respectively. 3. The results were compared which came from the sizes of turning circle measured up with the dumb card test method during the trial test and from the size of turning circle measured according to the DGPS positioning. The advance of the turning circle measured at the time of the starboard turning according to the DGPS positioning was 1m longer than that of the trial test. And it was 21m shorter at the time of the port turning. 4. The rudder was steered at $35^{\circ}$ of rudder angle each starboard and port while the ship M.S. A-RA was advancing at full speed of 13 k't. The velocity of the ship was reduced to 7.8 k't at $180^{\circ}$ of turning angle and 6.0 k't at $360^{\circ}$ of turning angle and mean values of turning angular velocity of the port and starboard were $2.4^{\circ}$/sec and $2.3^{\circ}$/sec, respectively. 5. The Z test at each $10^{\circ}$, $20^{\circ}$, and $30^{\circ}$ of rudder angle was carried out to have the maneuvering indices K and T measured. K for the each rudder angle were 1.24, 1.45, and 1.65 while T for the each rudder angle were 0.33, 0.20, and 0.14. That is, K at the Z test at $30^{\circ}$ was greater than at the Z test of $10^{\circ}$ and $20^{\circ}$ while T at the $30^{\circ}$ Z test was less than at the Z test of $10^{\circ}$ and 20.

This study was performed to analyze time series landuse pattern of urban areas and the change of the areas by using remotely sensed multiple sensors. The results were as follows. First, according to the result of time series analysis, most agricultural land has been changed into built-up areas by development work such as the land development or land readjustment project, arrangement of science parks or military facilities, and location of public establishment like government buildings. Second, if the expansion of built-up areas maintains the present scale and speed, it seems that a lot of parts of land would be changed into built-up areas, especially centering around agricultural land, so it is necessary to establish the plan for urban space. Third, I have synthetically collected the data of the project of urban development and systematically monitored the process of in expansion the built-up areas up to now (from the past). I hereby could lay the foundation that makes us scientifically forecast the direction of expansion in the built-up areas by the urban development in the future.

Sip and Byul-Gok (New tunes), as folks musics, are musical concepts opposite to that of the Court musics. They have the tunes. typical and universal. and Byul-Gok for singing. has the words in which the properties of melodies in the structures of compositions are reflected harmoniously. The Song. or Shiga. in Koryo-Sa, History of Koryo. Acjee and Acjanggasa. named ByulGok. is divided into two types. according to the characteries of the forms.: Koryo Sokyo. or the folk songs in Koryo. such as Chengsanbylulgok. and Segyoungbyulgok. and Kyonggichega, or nobility songs in Koryo and Chosen Dynasty. such as Hallimbyulgok. Kwandongbyulgok. and Jucgyebyulgok. In addition. Gasa. or the nobility and folk songs in Chosen Dynasty. such as K wandongbyulgok. also has the title. Byul-Gok. Even though these types of the songs have the same tittle. Byul-Gok, it is not appropriate that Byul-Gok is used as a term described as a branch of the literature: in light of music. they have the properties in common in the sense that they are opposite to the Court music. but. in light of literature. their forms are very different from one another. Therefore, it is appropriate that they are classified according to the characteristics of the forms, winters, the ideology of people who enjoy them, and periods: Sokyo, Kyonggichega, and Gasa. Byul-gok means not only the folks songs opposite to the court musics, but also the songs by setting words to the melodies present. Orignal tunes and their new tunes are not different musical compositions, but the same ones with the melodies which Korean acquired transcendentally. It is general tendency, at those times, that after compositions were made, words are set to them. Such words represent the politic thought in which courtesy and music are considered important. and the spirit with which the ruler and the people enjoy together.
