This study was undertaken with the aim to establish a reliable radioimmunoassay (RIA) system for urinary pregnanediol glucuronide (PdG) and to employ it for monitoring the reproductive status of dairy cows. Urine and blood samples were collected from the Holstein cows both pregnant and non-pregnant. The samples were then investigated for evaluating the relationship between progesterone ($P_{4}$) in blood and PdG in urine adjusted with or without urinary creatinine basis. Biweekly urine collection was employed for three cows in estrous and those artificially inseminated, while urine from pregnant cows was collected on a monthly basis. P_{4}$ and PdG levels were measured by enzymeimmunoassay (EIA) and RIA techniques, respectively. Our results indicated the sensitivity of PdG for RIA being 35 pg/tube and the recovery rate of 100%. Urinary creatinine concentrations also fluctuated within a day, but change at midday was not noteworthy. Regardless of the time of urination the change in concentrations of PdG was relatively smaller and did not vary significantly. The urinary PdG concentration showed periodic changes as that with serum P_{4}$ levels during the cow's estrus cycle. The correlation coefficient rose when creatinine level in urine was adjusted but the change was also not significant. The concentrations of PdG during the luteal phase were detected between 8.2 and 17.4 ng/ml, three to five times higher than that in the follicular phase. The concentration of PdG from pregnant cows (21 days after conception) was three to four times higher than in the nonpregnant cows. Our finding suggests that the determination of urinary PdG could be reliably employed for early pregnancy detection. The urinary PdG level continued to raise until 30 days pre-partum while the concentration reached its peak at 30 ng/ml, after which it started to fall 18 to 30 days before parturition and finally fell to its nadir value one week after parturition. As the correlation coefficient between the urinary PdG and serum P_{4}$ was higher than that corrected by urinary creatinine it can be suggested that the adjustment is not needed. The concentrations of urinary PdG could be maintained stably for 2 days in urine samples stored at room temperature and extended to 8 days when the samples were pretreated by boiling for 30 minutes. In conclusion urinary PdG concentration even without the need for creatinine basis adjustment can be used directly for monitoring the reproductive status of dairy cows.

Pulse condition is the essential division for conducting pulse diagnosis which is one of the most fundamental and important diagnostics in traditional Korean/Chinese medicine. We studied the pulse condition referred to classics of traditional medicine for a full understanding in present time and come to a conclusion like below. The reference to pulse condition was concluded to 'twenty four pulse conditions' which is the fundamental conception generally accepted in present age since it had first mentioned in "Huangdi Neijing" and after it had passed through "Nanjing", "pulse pattern identification-chapter of normal pulse"of Zhang Zhongjing and reached "Maijing"of Wang Shuhe. Although medical partitioners had different views to some extent about pulse condition, there were no significant differences in the main theoretical frame. Even though there had been a diversity of opinions on the classification of pulse-condition between various medical practitioners, the method of Dae-dae and the method of systematic endeavored by Zhou Xueting and Zhou Xuehai who were medical scholars in the Ch'ing dynasty have been a criterion for the classification of pulse-condition up to date. We were able to recognize that the change of pulse condition caused by pathological situation should be compared to physiological pulse condition for detecting the deficiency and excess by researching the analyzing methods of pulse condition mentioned in the "Lingshu", and the book of Hua Shou and Zhou Xuehai). To sum up, first normal pulse which is the physiological pulse condition should be a standard for detecting physiological pulse condition. Secondly, Zhou Xueting insisted that relaxed pulse should be a standard pulse condition for detecting normal pulse.

This research is focused on the 'Resident-participated Workshop' which targets the improvement of residential environment of apartment complex from the residents' point of view. The purpose of the workshop is to induce the residents interest and encourage them to participate in design process, thus, residents will be satisfied with the result with affection and achievement. This research aims the effectiveness of 'Resident-participated' design plan as a program which enables them to maintain and self manage in the long run. The object of this research was the public space within the apartment complex of Susojugong Rental Apartment Complex in Gangnam-ku, Seoul and followings are the contents; 1. Method of 'Resident-participated Workshop'. 2. Program of 'Resident-participated Workshop'. 3. Design analysis of improved apartment complex through 'Resident-participated Workshop' and selection. As a result, it was noticeable that 'Resident-participated Workshop' was an important factor in decision making of designs from the very first stage through communication. As a part of workshop program, design game used cubic models which was useful to enhance the understanding of the participants. It also induced the cubic conception so that intercommunication with the design specialists was possible. But, the development of various workshop method to increase the residents' interest and participation is necessary, especially, program development is required to change the residents' attitude towards the design plan. It is anticipated that a continuous related research is neccsary in this regard.

This study was aimed to understand the structures of preservice secondary school teachers' alternative conceptions on radioactive isotopes in the interior of earth. The structure of their conceptions were analyzed by the suggestions of Niaz (1988) based on the Lakatosian frameworks. The survey was carried out on a group of seventeen students who were major in science education. The research method was open-ended written questionnaire. The results of this study show that students had apparent alternative conceptions. The high temperature and pressure' explanation for radioactive decay in earth's interior had most import effects on their alternative conceptions. It was also intended to survey their conceptional change by our teaching strategies of the philosophy of science in order to construct science concepts.

This thesis is designed to take a close look into the characteristics of architectural space through the standard of beauty, which has been created apart from our desires at certain cultural or historical periods of time. It will try to construct the outline of conception about the beauty throughout many centuries. First of all, contents of the research will focus on the aspects, which people have been considering as beauty eversince the ancient time without having any assumptions on its concept. For example, if the beauty of art has been accepted by the theories of modern aesthetics while degrading the beauty of nature, its value could have possibly been much more appreciated. The standard of beauty has been going through the process of change in such history of mankind. The general standard of beauty, which was established in the ancient time was the proportion and harmony between many elements. Afterwards, beauty was expressed as colors and light in medieval times. Expression of beauty using ugly features such as monsters or demons also existed at the time. Beauty has been periodically developing from supernatural to gracious, rational, noble, romantic, religious, mechanical, and today's media. The concept of beauty established from the above has been appearing throughout various culture such as dress and decoration at the given period of time. It would later affect the formation of space as well as decoration for architectures and styles. It will be analyzed throughout the five design elements; style, composition, materials, components, and form. The thesis would like to find the spatial order of beauty from the result of the analysis. The analysis will examine the possibility for which the recomposition of beauty will be provided as a design process for the new era. The Greek beauty represents a shape. The shape represents proportion and the proportion represents given numbers. However, beauty is being expressed by the opposite process at the present time. In other words, computers will arrange the numbers, which would formalize the proportion between the numbers. Beauty would be presented when the shape is presented as certain forms.

Frank O. Gehry is hewn to be an architect whose design 1anguage is so arbitrary and so unexpectedly changing that it seems to be almost impossible to trace any common language or my coherence over his entire career and works. To provide a counter-argument to this conception, this study explores the transformation pattern of the design language commanded by Gehry through his works. To pursue this study, Gehry's career was divided into four periods according to the design characteristics, and thorough analysis was conducted on the transformation pattern of the language both synchronically and diachronically. Based on the analysis, it was found that Gehry had been always trying to metaphorically embody the synchronic context of any given Period into his works, and the vehicles of this embodiment were materiality and morphology. Finally the argument of this study is that the changing process of Gehry's design language is not any "revolutionary change," as it was known to be, but 〃evolutionary transformation. "on."

The purpose of this paper is to investigate if any effects of GI cooperative learning method, which is compared to the effects of traditional competitive teaching-learning method on the students' academic attitude in middle school social studies classes. Conclusively, it is asserted to be a much more effective teaching-learning method. Some statistical evidences were gathered by questionnaire method just after the experimental classes being applied for a semester to the 241 first year middle school students in a small city. Using the t-test procedure, it is conformed that GI cooperative learning method can draw much more positive changes in the academic attitude of the students. In short, such positive changes in student's academic learning attitude can be related with the increase of self-trust in learning processes, the change in the conception of the subject, and the spontaneous interaction and verbal communication among the group members.

In these OECD countries, left-wingers Government focus on unemployment, but right -wingers Government cares more about inflation. It is that inflation and unemployment don't have differential effects across rich and poor and the happiness levels of these two groups are unaffected by identity of the Government in power. The poor people choose to left-wingers Government, but rich people prefer to right -wingers Government. I estimate whether above opinion is correct or not. Especially I check how my results change when I control for aggregate economy activity and government consumption, two variables that could be correlated with inflation and unemployment and affect each Government's happiness differentially. This paper, and I believe much of the happiness literature, can be understood as an application of experienced utility, a conception that emphasis the pleasures derived from private consumption and sentiment of it. In Granger Causality test, private consumption sentiment index related with industrial production interactively in Korea. The business cycles affect on private consumption sentiment index.

The purpose of this study is to typify femininity and masculinity represented in mainstream women's and men's fashion magazines in Korea since 2000 and infer sexual ideology appearing in contemporary Korean society by content analysis with the view of plural sexuality. For the content analysis total 259 editorial fashion photography was analyzed. As the result, 5 femininities and 5 masculinities were typified, and then sexual discourse was inferred out of the frequency of each type and texts with the images. On the basis of previous studies and historical considerations of this topic, the types of sexuality represented in mainstream fashion magazines in Korea since 2000 were classified as follow.: in women's fashion magazines Traditional Femininity and Androgynous Femininity were almost similarily dominant sexuality, and Glamor Femininity, Babydoll Femininity, and Genderless sexuality were alternative. Meanwhile, in men's fashion magazines Traditional Masculinity formed clear dominant sexuality, and Macho Masculinity, Androgynous Masculinity, Adolescent Masculinity, and Genderless sexuality were alternatives. In addition, Androgynous Masculinity in women's fashion magazines occupied the highest frequency, while Glamor Femininity in men's fashion magazines did so. From this sexual discourses represented in mainstream fashion magazines in Korea since 2000 are as follow.: First, mainstream fashion in Korea sticks to the modern values preserving traditional sexual ideology even in this postmodern period of the former 21C. Second, Androgynous Femininity as another dominant femininity with Traditional Femininity connotes the change of conception of femininity in Korean society. Third, Androgynous Masculinity to females is preferred, while femininity to males is still regarded as fetish or adorned object. Fourth, the appearance of various alternative sexualities leads to pluralization of sexuality, and then fashion gradually codifies youthfulness and feminine values, such as body and sexual desire more than before.
