The indirect fluorescent antibody test (IFAT) for cysticercosis was accomplished with the sectioned cyst wall tissue antigen which was made with the cyst in the fourth ventricle of human brain. The antigen was revealed on the tegument, nuclear layer and internal surface of the bladder wall with FITC conjugated IgG fraction goat antihuman immunoglobulins. Total 236 sera were tested which were obtained from 24 cases of confirmed cerebral or dermal cysticercosis patients, 33 cases of suspected cysticercosis, 50 cases of intestinal or tissue invading larval cestodiasis, 50 cases of trematodiasis, 14 cases of nematodiasis or elevated eosinophilia and 65 cases of non-infected control sera. The serum titer of 1:16 or over was regarded as positive. Twenty three out of twenty four (95.8%) sera from confirmed cysticercosis patients were positive. Serum titer of 65 non-infected controls showed 1:8 or below. Twelve cases out of thirty three (36.4%) suspected cases of cysticercosis were revealed as positive. And cross reactions were observed in taeniasis solium (40.0%), taeniasis saginata (13.3%), diphyllobothridiasis laturn (11.8%) and lonorchiasis sinensis (2.8%). The mean titer of cerebral cysticercosis (7.60 in log₂) was higher than those of mixed (5.61 in log₂) and dermal cysticercosis (5.44 in log₂). The titers of cerebral cysticercosis patient's sera who were treated with praziquantel were not changed at least within six months in four cases out of seven followed up cases. In four to five year after treatment with praziquantel it showed decreased or negatively converted serum titers. Conclusively, it was indicated that indirect fluorescent antibody test using the sectioned antigen of Taenia solium cysticerci was applicable to the diagnosis of cysticercosis.

In order to provide the technical guidance for heat treatment process of a back-up roll which is a rolling part of a press for hot iron, unsteady solutions of temperature distributions, in which thermodynamic properties of specific heat, Cp and thermal conductivity, K are a function of temperature, are solved by finite-difference numerical method. First, unsteady solutions to heat conduction equation with the known surface temperature in a infinite solid bar are investigated to obtain proper thermodynamic properties and the surface heating rate of the roll. These solutions are also compared with the calculated and experimental data reported by kobe iron company. Second, the unsteady 2-dimensional solutions with radiative and convective boundary conditions in a real roll with irregular shapes are obtained, where the numerical method of the Implicit-Alterating-Direction is used. From these calculation, the following results are obtained. 1) The heating area near the surface of the roll, which is a important place for the heat treatment, does not much depend on variation of thermodynamic properties of the roll. 2) A high or low limitation of the surface heating rate is considered. 3) The thermal radiation analysis with the weighted sum of gray gases model is effective to predict the gas temperature in the furnace. 4) The even insulations on both side of a real roll are required to obtain a uniform heating temperature contour near the surface.

As average lifespan in human increased, women's concerns about health promotion after postmenopause are increased. Osteoporosis causes the serious health problem in postmenopausal women. We investigated comparison between Seoul and Chungju for women's recognition about osteoporosis to utilize patient's education data. Information, concerning whether the osteoporosis was well understood, were gather 405 patients, who visited an university hospital from January 1 to April 30, 2001. The mean age of 201 women in Seoul is 46.39 years old, and mean age of 204 in Chungju is 46.35 years old. Among 201 women in Seoul, 43(21.4%) women answered "well known" osteoporosis, and 32(15.9%) women answered "unknown" osteoporosis. Among 204 women in Chungju, 24(11.8%) women answered "well known" osteoporosis, and 32(15.9%) women answered "unknown" osteoporosis. There were significant association between recognition of osteoporosis and their education level, but not significant related with their economic level. Subjective and objective recognition for osteoporosis in Seoul was relatively higher than women in Chungju, but compliance about doctor in Chungju was relatively higher than women in Seoul. But we found that recognition level of postmenopausal osteoporosis is low in Seoul and Chungju. We concluded that knowledge for osteoporosis was relatively low, seoul was relatively higher than in Chungju. Therefore, correct patient education for prevention and treatment of osteoporosis would be needed.

The past manpower-dependent method in the constructional industry has raised the problem of high cos - low efficiency. Especially construction of staircase by using conventional form work and concrete placement deteriorates the quality of reinforced concrete, requires many manpower and has many difficulties of work. This study introduces COSEC system(RC _Co_re _Se_quential _C_onstruction Method by Using PC stairs) to reduce the manpower and the construction time and improve quality of structure. This is the new epoch method of installing PC stair elements after the construction of core wall contrary to the existing method of installing PC stair elements before the construction of core wall or at the same time. After reinforced concrete core wall is constructed by the system form in advance, PC landings and stairs are took in and set up between core walls standing right opposite. PC landings are connected by pinned connection with the core wall and PC stairs are simply put on PC landings on both sides. This system makes installation of PC stair elements very easy and improves the quality of stairs and core wall. This study shows the effect of practical application to construction of the building in the field.

미국과 영국의 교육사회학에서의 여성연구 : 1980∼1986

오욱환 이화여대 한국여성연구소 1987 여성학논집 Vol.4 No.-

The main theme in sociology of education has been the educational inequality and its effect on the inequality of life chance. Sexual inequaility is pervasive in education and society. Among structural inequalities, the sexual inequality has been accepted to be the most natural. The sexual discrimination is the outcome of the systematic combination of social structure, ideology, and culture. It looks impossible to solve the sexual inequality in this society. To equalize the sexual inequality, various ways of approaches are needed. One of the most important ways is to study the sexual inequality, which is called 'women's studies.' 'Women's studies' have not been focused in the sociology of education in Korea of the as well as in other countries. the researcher argues that the topics of the sexual inequality should be included in the sociology of education because the inequality is also prominent in korean society. The theme of 'sex and education' can be found in the syllabus by the researcher for undergraduate and graduate schools. The theme can be found in the related courses as well. Yet, the researcher feels it is not well organized because of limited references from educational journals or other sources. This study of reviewing the articles about women's studies in the field of the sociology of education has two purposes : one is to compare the articles in women's studies published in American society with those of British society, and the other is to academically invite the female college students, particularly graduate students, to the women's studies. Most female college students in Korea are not conscious of their disadvantaged situation. Even though a very few female students are conscious of their situation, they are unnecessarily militant toward the sexual discrimination only on the basis of their own personal experience. Their arguments have not been supported by academic knowledge and empirical data. For studying the sexual inequality it is necessary and inevitable to read the articles of the academically advanced societies. In this study, the researcher selects two journals : one is Sociology of Education, which has been published by the American Sociological Association since 1961, and the other is British journal of sociology of Education, which has been managed by British sociologists and sociologists of education since 1980. this study analyzes the articles of women's studies in Sociology of Education and BJSE from 1980 to 1986. During this period, Sociology of Education published 137 articles and BJSE 107 articles. among these articles, the researcher selected the articles focused on women's studies on the basis of having the sex/gender-related word, such as gender, sex, femininity, patriarchy, and musculine in the research title. among the above articles, 19 articles in Sociology of Education and 14 articles in BJSE were selected to analyze according to the study interest. The ratio to the total of each journal is 13.87% (19/137) and 13.73% (14/107), respectively. The sociologists of knowledge have asserted that knowledge is the historical and socio-cultural product. The research is the practical process for making knowledge. Therefore, it is more actually affected by the social situation. Women's studies have been conducted to remove the socially-produced structural and ideological barriers by which women are oppressed, dominated, and limited to life chance. The social situations of the nations are different and, the definitions of the situation are also different, The differently-defined situation makes the researchers to keep diverse perspectives. One's perspective determines his/her research topics. The topics in Sociology of Education are significantly different from those of BJSE. The American researchers are more concerned to know how much serious the sexual discrimination/difference is. The British sociologists of education have many deep-rooted questions about the sexual inequality. They have tried to reveal the unjustifiable structural and ideological mechanism to function against women. Topic determines the way to approach. The difference in the topics between the two nations causes the difference in research methods. The american researcher prefer to the empirical study using high-level statistics. On the contrary, the researchers in BJSE are inclined to approaching theoretically and/or to doing ethnography. Theory is more decisive than empirical data. Therefore, it is better to evoke action. Though ethnography is a kind of case study, it is very persuasive because it describes the reality by the eyes of the tribes, not by the intentions of researchers. The differences in the topics and the research methods cause the variations in the alternatives to solve the present problems. Almost articles in BJSE argue the change of social structure and ideology, and particularly the school knowledge which is used to reproduce the capitalist and patriarchal social relations. The alternatives are relatively radical and some of them are based on the Marxist sociology. Some American researchers suggest the gradual progress to the sexual equality. The others do not suggest any alternatives. In women's studies included in the sociology of education. the topics, the methods and the alternatives are significantly different between American and British societies. This can be interpreted in terms of the differences of the historical and socio-cultural background. This fact implies that we can not expect the research findings of foreign countries to be directly applicable to our social problems, including the sexual inequality.

In domestic construction industry, re-bar work is one of the conventional works that have low productivity and are done by outdated method that is mainly independent on just manpower. And in urban area construction project, the basement covers all of the site, so there is no enough space for stocking and manufacturing re-bar. Nowadays re-bar factory manufacturing is widely spread for coping with this actual problem and developing the outdated re-bar work. But there is little development of re-bar factory manufacturing from its beginning and the dissonance is growing in the job-site using re-bar factory manufacturing. So in this study, we analysed the status of re-bar factory manufacturing and suggested the application method of re-bar factory manufacturing for more practical use. The results of this study are as follows. For successful adaption of re-bar factory manufacturing (1) the partnering of the participants is very important. So in the time of making contract, the method for improving partnership must be considered. And (2) for lessening the re-bar loss in factory manufacturing, it is considered using the Coil re-bar. Finally (3) for making the work process between job-site and factory more streamlined, it is needed making the standard of bar-list shape ID.

The purpose of this study is to develop application method of structural welded wire fabric(WWF) for practical use in domestic construction industry. One of the main problems of adapting WWF for building construction is the various types of fabric, so the productivity in the factory and in construction field is decreased. The result of this study are as follows. The shape of welded wire fabric was proposed for application in slab and wall(especially the shape of WWF for slab should be one direction reinforcement type). And economical advantage of WWF was analyzed. WWF could be adapted 80.4% cost of SD400.
