金健洙,玉明哲 명지대학교 1982 明大論文集 Vol.13 No.-
This is a comparative research of the reaction between field and track events' players and other players, and it was tried out for an analysis of what kinf of results took place. Especially, in this research, 100V-bulb, 100W, 60W, 30W, 10W were used as buzzer and light, and measured simple Reaction time, whole body Reaction time, field and track crouching-start Reaction time in five groups separately. Persons in custody were mainly students of Myung Ji University and player's group, field and track events' players were Han Kook National College of physical Education. Results were analyzed by Random-sampling in all 70: field and track events' players, 10; general students, 17; Physical Education department's students, 21; football team, 12; basketball team, 10. As mentioned above results, conclusions are as follows: 1) The mean value of the reaction time to buzzer and light stimulus of each test group came to results as follows. A. In the Case of simple reaction, when buzzer stimulated, basketball team students were fastest; 0.150sec(high), 0.161sec (low), the second, field and track team students; 0.152sec(high), 0.180sec (low), football team students; 0.167sec (high), 0.184sec (low), P.E. department's students; 0.250sec (high), 0.226sec (low), the lowest-general students; 0.420sec (high), 0.284sec (low). As these results are measurement chronometry of using shoulder articulation mainly, I think that basketball team students who use hands frequently are in the leading position resolutely. B. In the case of whole body working time, small differences are shown and the fastest reactions are shown in field and track team; 0.230sec (high), 0.233sec (low). The second, football team; 0.233sec (high), 0.235 (low), P.E. department students; 0.257sec (high), 0.183sec (low), (In bass P.E. department students were the fastest in reaction time). Basketball team; 0.268sec (high), 0.264sec (low), general students; 0.322sec (high), 0.336sec (low). C. Reaction time of crouching-start as group-to-group comparison was fast also in the group of useing feet frequently. field and track team was the fastest; 0.161sec (high), 0.123sec (low), the second, football team; 0.175sec (high), 0.173sec (low), basketball team; 0.181sec (high), 0.176sec (low), P.E. department students; 0.243sec (high), 0.266sec (low), general students; 0.261sec (high), 0.262sec (low). 2) Reaction time of luminous intensity in each team was results that buzzer was more stimulant to reaction than light. 3) Reaction time of luminous intensity of each testing group was shown according with intension of stimulus to bright light, and the reverse phenomenons came out. 4) Reaction of the tone of buzzer to the buzzer in each group was shown that reaction time to a loud buzzer was fast in superior groups, and in other groups, in a bass.

For the improvement of the detection method of leprosy bacilli from leprosy patients, the author attempted to detect leprosy bacilli using a nuclepore membrane filter. The specimen were obtained by skin scraping from all the tested patients with leprosy and treated with 0.025% trypsin and 0.002% Tween 80. The nuclepore membrane filters used in this study were three kinds : 0.4 and 0.2㎛ in pore size of 25㎜ in diameter, 0.2㎛ in pore size of 13㎜ in diameter. The results of the bacterial detection rate by the common skin scraping smear method and nuclepore membrane filter method were compared. The results were summarized as follows : 1. The bacterial detection rates by the nuclepore filter method(25㎜, 13㎜ in diameter) were significantly higher than the bacterial detection rates by skin smear method. 2. There was no significant difference between bacterial detection by 0.4㎛ in pore size, 25㎜ in diameter nuclepore filter and 0.2㎛ in pore size, 25㎜ in diameter nuclepore filter. 3. There was no significant difference between bacterial detection rates by 0.2㎛ in pore size, 25㎜ in diameter, nuclepore filter and 0.2㎛ in pore size, 13㎜ in diameter nuclepore filter. 4. Although the bacterial indices by skin smear were "―", bacterial detection negative. the number of bacteria by nuclepore filter were about 3.2×10 exp (2)/ml. From the above results, it was suggested that on the microbiologic examination from leprosy patients, bacterial detection by skin smear method in the first place should be carried out : and than if the results gave negative, bacterial detection by nuclepore membrane filter method after treatment with trypsin and Tween 80 should be done.

The purpose of this paper is to examine how the Korean perceived the internal and external conditions of those days in process of overcoming the internal and external challenges at the end of the Yi-dynasty, how they concentrated and developed the confrontation consciousness for self-existence of their nation, and after all what characteristics were offered on the modern Korean political ideas. As the West-European impacts were began since 1860's, the Korean got a new cognition and self-consciousness and got a crisis consciousness for self-existence of a nation at the same time. Especially, the Japanese advance of capitalism into Korea was proved to be typical imperialistic invasion of capitalism. As finally Korea was fallen down to the Japanese colony, rebellious consciousness of nation for the recovery of sovereignty was elevated by the Korean national consciousness. On this historical situation, the Korean developed various political movements as the practical form of their national liberation with awakening of national consciousness for the independent liberation from the outside power, especially the Japanese imperialism. The Korean had various political ideas such as the Confusion traditional morales, Enlightenment and Religious Mobilization-the Tonghak (eastern learning) in the historical situation since the opening of the port. But their nationalism was a consistent political ideas including such various ideas. Confrontations and entanglements between the Confucian traditional group-the Ui Jung Chuk Sa pa (爲正斥邪派) and The enlightenment group-the Ke Hoa pa (開化派) were incurred because each party insisted on his own logic, but the critical situation at the end of the Yi-Dynasty drove them into the ideology of nationalism over their own insistence. And the excluding group of external civilization. In searching of national self-experience and modern aspiration, whether it was the Ui Jung Chuk Sa pa by excluding or the Ke Hoa pa flowering and keeping themselves by accepting civilization, both were lying in such an urgent situational condition that self-regulation and independence of political system were a point of losing. Under the urgent condition like this, nationalism which brought about being on the basis of ideology was featured defiant nationalism by having resistance for conditional recognition. A righteous army movement which was based on the excluding group of external civilization was a national movement for recovery of her right against the enlightenment and the invasion. It is defined, as a military-forced political movement, Under colonial governing of Japan this movement recognized the necessity of armaments for independence, and developed the military forced resistance as political movement. The movement of patriotic-enlightenment based on the idea of enlightenment, was the practical form of modern bourgeoisie's enlightenment and it's goal is the restoration of national right and the construction of the modern national state. However, the perform of the enlightenment movement conformed peaceful enlightenment practical movement which emphasized national consciousness and whose characteristic was defined rebellious nationalism political movement against the Japanese domination. As I described so far, the characteristic of modern political idea of Korea was rebellious nationalism aspect and it had two contents ; one of them can be defined rebellious nationalism the movement as for recovery of governmental power which contains the internal and external historical condition, especially relating independence against the Japanese domination, and the other can be defined rebellious nationalism movement as the movement for recovery of governmental power which developed patriotic enlightenment movement pursuing the construction of the modern national state.

Plastic materials called synthetic polymers are comparatively new ones that are synthesized chemically, different with natural materials such as wood, paper, stone, metal, glass, etc. Especially, the usage of the plastic materials in food industry is really various in packaging film, flexible packaging material and containers for a variety of foodstuffs. However, it is true that the environmental contamination problems such as environmental hormone leakage due to incineration or reclamation, difficulty in securing a reclaiming site, and detection of deadly poisonous dioxin, etc generated by incomplete incineration of waste plastic materials become social issues. To solve these problems, it is urgent to develop and commercialize degradable plastics that can be stably and conveniently used as like general plastics during the use and that are environment-intimate and non-harmful plastics easily decomposed by sunlight, soil microbes, heat generated from a reclaimed land and so on after the use.
