This study aims at the structural analysis of vibration and fatigue according to the configuration of engine mount. Maximum equivalent stress or deformation is shown at bracket or case respectively. As harmonic vibration analysis, the maximum displacement amplitude is happened at 4,000Hz. Among the cases of nonuniform fatigue loads, 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' or 'Saw tooth' becomes most stable. In case of 'Sample history' or 'Saw tooth' with the average stress of 4,200MPa or 0MPa and the amplitude stress of -3,000MPa or 7MPa, the possibility of maximum damage becomes 70%. This stress state can be shown with 7 times more than the damage possibility of 'SAE bracket history' or 'SAE transmission'. The structural result of this study can be effectively utilized with the design on engine mount by investigating prevention and durability against its damage.

This study was performed to examine the clinical discussion records where Lee Gong-yoon, participated in Royal treatment at Joseon Dynasty, was involved. Lee Gong-yoon who scouted from the outside had participated in the medical center of the Royal Family for several years as a royal doctor. But he preferred aggressive prescriptions and behaved indiscreet. Eventually, he was exiled when Kyung-Jong who was the 20th king of the Joseon Dynasty died. He was harshly criticized until the year crown prince ascended the throne following Kyung-Jong. But some officials started to defend him since March of the next year. They recognized Lee Gong-yoon's aggressive prescriptions and indiscreet behavior. But mentioned that some very aggressive prescriptions didn't come from his own idea. After they proved their insistence true, his place of exile was changed from island to outland. Different from other doctors who focused on patients' 元气 ($yu{\acute{a}}nq{\grave{i}}$), Lee Gong-yoon focused on removing patients' symptoms when he decided to cure a disease. And also he had considerable insight of "醫學入門 ($y{\bar{i}}xu{\acute{e}}r{\grave{u}}m{\acute{e}}n$)". Despite of his high degree of medical knowledge, unconventional character and behavior made the end of his life unfortunate.

This study investigates structural, fatigue and modal analyses at bicycle suspension seat post. When weight is applied to the saddle, models 1 and 2 have the weakest strength at the part connected with saddle. And model 2 is greater total deformation and equivalent stress than model 1. Among the cases of nonuniform fatigue loads at models 1 and 2, 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable. In case of 'Sample history' with the average stress of 0 to $-10^4MPa$ and the amplitude stress of 0 to $10^4MPa$, the possibility of maximum damage becomes 4%. This stress state can be shown with 5 to 7times more than the damage possibility of 'SAE bracket history' or 'SAE transmission'. Model 1 has better impulse relaxation and passenger sensitivity than model 2. The structural result of this study can be effectively utilized with the design of bicycle suspension seat post by investigating prevention and durability against its damage.

This study aims at the structural analysis with fatigue according to the configuration of railway vehicle wheel. Maximum equivalent stress or deformation is shown at the lower face in contact with wheel and rail. As model B has the maximum stress or deformation which becomes lower than model A, model B is shown to have more durability than model A. Among the cases of nonuniform fatigue loads, 'SAE bracket history' with the severest change of load becomes most unstable but 'Sample history' becomes most stable. In case of 'Sample history' with the average stress of 0 to $-10^{11}$ Pa and the amplitude stress of 0 to $10^{10}$ Pa, the possibility of maximum damage becomes 3%. This stress state can be shown with 6 times more than the damage possibility of 'SAE Bracket history' or 'SAE transmission'. The structural result of this study can be effectively utilized with the design of railway vehicle wheel by prevention and durability against its damage.

In this study, the life of Lee Kyo Seung(1868~1951), the author of SinJeongSanSul(1~3), is traced in outline. He worked as a teacher at a government elementary school from 1895 to 1906. He contributed to elementary education as one of the first government elementary school teachers in the period of the Great Han Empire. During this period, he wrote SinJeongSanSul(1~3). He contributed to secondary mathematics education as a professor at Sungyunkwan for three years from November 1908, and as a mathematics teacher at the YMCA Academy from 1906 to 1916 in the period of the Great Han Empire and early Japanese colonial period. During this period, he wrote two different secondary school mathematics textbooks. During the Great Han Empire and early Japanese colonial period, he was a pioneering textbook author and mathematics teacher. So he can be evaluated as one of the important persons in the history of mathematics education in Korea.

Objective : The writer has come to see that a study of the Theory of Ministerial Fire of JuDanGae presupposes a study of earlier theories of fire. Therefore, I have analyzed and studied the theories of fire presented by medical doctors since "Nae Gyeong(黃帝內經)" Method : To begin with, I have studied the concepts of grand fire(壯火) and small fire(少火), imperial fire(君火) and ministerial fire(相火) in "Nae Gyeong", and have construed the meaning of human fire(人火) and dragon fire(龍火) by Wang Bing(王冰), and fatty fire(膏火) by Sohn Sa-mak(孫思邈). Next, I have studied true fire(眞火) by Huh Sook-mi(許叔微) and true yang(眞陽) and pit fire(坎火) by Eom Yong-hwa(嚴用和), Theory on Right Kidney as the Gate of Life and Ministeiral Fire(右腎命門相火說) by Yu Wan-so(劉完素), and the reason why Jang Wan-so(張元素) asserted Theory of Three Burners as Ministerial Fire(三焦相火說). Result : I have understood the influence that the concepts of grand fire and small fire, imperial fire and ministerial fire in "Nae Gyeong"have exercised on the later medical doctors, and have also understood the physiological and pathological Fire that influences the human body. Moreover, I have seen that Fire, as discussed by scholars from Huh Sook-mi and Eom Yong-hwa to Yu Wan-so and Jang Wan-so, made great contribution to the later development of Theory of the Gate of Life, getting its entire picture in Eum Hwa. Conclusion : Seeing that the theories of Fire presented by medical doctors since "Nae Gyeong" and prior to JuDan-Gae had great influence on the later development of Theory of the Gate of Life, I have come to understand that along with Eum Hwa by Lee Dong-wan, they must precede a study of the Theory of Ministerial Fire of JuDan-Gae.

Purpose: This study was to prepare the basic data for prevention of colorectal cancer and protection against its spread. Method: The subjects for the study were 204 patients with colorectal cancer from the G.S. wards of five general hospitals in Busan for the period of June 1 to September 1, 2001. The instrument used was a questionaire which was developed by Junho Shin(1995). The data was analyzed by descriptive statistics, McNemar test, ${\chi}^2$ test, paired t-test, and ANOVA. Result: 1. 57% of the studied subjects were male, 42.7% were more than 60 years old, 54.9% were of standard physique, 49.5% were the Buddhists, 50.5% were the middle or high school graduates, 83.8% were city dwellers, 48% were jobless, 69.6% had no-history of alimentary disease, 44.1% had no-family history of cancer, 82.8% were married. 2. Constipation (${\chi}^2=36.45$, p=0.0001) in clients showed a significant positive association for the prediagnosed, but diarrhea(${\chi}^2=3.947$, p=0.047) showed a significant positive association for the post-diagnosed. The preference for high seasonings(t=6.23, p=0.0001) and animal fat (t=8.35, p=0.0001) was higher significantly in the pre-diagnosed, but physical activities(${\chi}^2=30.22$, p=0.0001), an eutrophic or tonic medicine(${\chi}^2=30.22$, p=0.0001), was of and vegetables(t=-6.20, p=0.0001) was higher significantly in the post-diagnosed. 3. There were significant differences in the life style of the pre-diagnosed according to the general characteristics except religion. Conclusion: Results of the above study reveal we should be very sensitive to the change of defecation styles and consider the necessity of improving life styles as regards eating habits. When an education program is developed, the general characteristics of the subjects need to be considered.

Purpose : The purpose of this study is to analyze the history of nursing and medicine as phenomena of knowledge/power from the viewpoint of Foucault. Method : The present study adopts the genealogical method by Foucault, which tries to unite languages and knowledge. Foucault who attempted to show that the basic ideas which people normally take to be permanent truths about human nature and society change in the course of history. Results : It has been emphasized that the development of modern health care has been due to the progressive efforts of medicine and to medical discoveries. Foucault examines the institutionalization of knowledge and the power exerted thereby, with special reference to the devices of social regulation and their function over the madness, the disease, the crime, and the sexuality. The concept of power is that it is exerted spontaneously in verbal behaviors of individuals through knowledge of everyday life such as definition of body or mind. Therefore as to the problem of knowledge/power, this study tries to understand the meaning of history of nursing and medicine through an analysis of the formation of text of history. In order to have authority in a power relation, the medical professional asserts that medical discourse is the most scientific knowledge. Conclusion : According to the above findings, it can be concluded that the body is also directly invested in a political field: power relations have an immediate hold upon it; they invest it, mark it, train it, torture it, force it to carry out tasks, to perform ceremonies, to emit signs. Therefore the devaluation of nursing care is reinforced by the medicine which has the legitimate authority through use of the political skills about the body.
