The purpose of this research was intended to investigate drag queens' and drag kings' gender identity not only as a comic and desexualized drag borrowing external characteristics of the opposite sex but also as the subject visualizing and performing' the third sex'. It also aimed to examine formative aesthetic characteristics and aesthetical value of drag queen's and drag king's fashion and to confirm the functions of drag queen's and drag kins's fashion to establish, visualize and Perform the discordant sex. For this process, research steps were as follows : 1. Understanding drag, drag queen and drag king in social, psychological context as well as in gender context. 2. Finding visualized forms which drag performance interchange with mass media 3. Analyzing similarities and differences between drag queen's fashion and drag king's fashion. 4. Examining the aesthetical characteristics and the value of drag queen's and drag king's fashion. The results of characteristics of drag queen's fashion could be categorized into stereotype, mimicry, kitch, inconsistency and commercialism. And the characteristics of drag king's fashion could be divided into reality, self-consciousness, mimicry, inconsistency, subversion and multiplicity. Drag queens create plausible impressions of feminity through the use of wigs, dresses, jewelry, makeup, hormones and through &role Playing&. Similarly drag kings produce a plausible masculinity taking gay male aesthetic using suits, crotch stuffers, facial hair, and greased hair. Male and female impersonation produce very different notions of gender performance for male and female embodiment. Drag kings' performance of masculinity demands authentic property of bodies so rather nonperformative, while drag queens' performance of femininity depends on more visible and theatrical fashion.

The objective of this study is to investigate the changes in concentrations of blood urea nitrogen (BUN) and sex steroid hormones, such as estrogen, progesterone, and testosterone in Korean cattle (Hanwoo) with reproductive disorders and to examine the relationship between BUN and body condition score (BCS) in Hanwoo. The concentration of BUN was 16.2 mg/dl, 17.8 mg/dl, 15.1 mg/dl, 17.9 mg/dl, and 28.3mg/dl in pregnancy, repeat breeding, follicular cyst, luteal cyst, and ovarian atrophy, respectively. In Hanwoo with BCS $2.0{\sim}2.9$, $3.0{\sim}3.5$ and $3.6{\sim}4.0$, the concentration of BUN was 15.8 mg/dl, 17.0 mg/dl, and 17.6 mg/dl, respectively. Fluoroimmunoassay showed that serum estrogen and progesterone levels were decreased in reproductive disorders Hanwoo, such as ovarian atrophy, endometritis, and weak estrus. The testosterone level was significantly decreased in Hanwoo with reproductive disorders compared to that in pregnant Hanwoo ($0.02{\sim}0.03\;ng/ml$ vs 0.13 ng/ml, p<0.05). The progesterone and estrogen concentrations in follicular fluid obtained from ovary with follicular cyst were significantly higher (p<0.05) than those in normal follicle fluid. These results show that there is no relationship between BUN and BCS in Hanwoo, and the concentration of sex steroid hormone in serum and follicular fluid are changed in reproductive disorders Hanwoo.

The climacteric is that phase in the aging process during which a woman passes from the reproductive to the non-reproductive stage. The signals, such as hot flashes, vaso-motoric disturbances, perspiration, stiff shoulders, emotional symptoms, are refereed to as climacteric disturbances. Treatment of climacteric symptoms centers on estrogen replacement and transquilizers, but there are many problems to be solved to use these hormones/drugs as far as dosage, duration and complications are concerned. The care of women during the climacteric years should provide relief of distressing symptoms with as high a degree of safety as possible. From this viewpoint, we used red ginseng powder to those patients with high menopausal index successfully. We studied its mechanism of action and proved that red ginseng improved the micro-circulation system via improvement of erythrocyte deferability which enhanced sex steroidgenesis consequently

Estrone, which is obtainable from 19-hydroxycholesterol acetate through microbial oxidation, was chemically transformed to orally active estrogens, ethynylestradiol and methylestradiol. For progestin synthesis, $5{\alpha}$-bromo-619-oxidoisoandrosterone, was harvested from the culture broth(ATCC:19170), in which $5{\alpha}$-bromo-619-oxidocholestanol, acetate was added as a carbon source. Methylestrenolone, a potent orally active progestin, was synthesized from the harvested product via several reactions. Norethindrone, a popular progestin, was also prepared from 19-norandrostenedione. 19-Norandrostenedione is also available through microbial oxidation and chemical modification of $5{\alpha}$-chlor-619-oxidocholestanol, acetate.

Hormone이 암발생과 밀접한 관계가 있음은 이미 1935년대에 밝혀진 바 있다. 즉 lacassagne은 estrogen이 토끼 자궁벽의 fibromyomatous transformation에 영향을 준다고 하였다. Nelson는 guinea-pig를 시험동물로 해서 estrogen을 장기투여한 결과 uterine fibroids가 수발됨을 확인한 이래, 유발됨을 확인한 이래, 이러한 hormone이 암발생의 장기요인이 됨으리 밝히게 되었다. 이러한 업적은 Lipschutz에 의해 더욱 수식되었다. 이러한 업적의 결과가 여러편의 종설로 발표되었다. 즉 Lacassagne, Zuckerman, Burrows등, Gardner는 각기 종설을 발표하여 이를 확증하기에 이르렀다. 한편 각개 hormone, 그중에서도 sex-hormone의 opposite action은 Steinach등 및 Sand에 의해 밝혀졌고 거세백서에 estrogen을 투여했을때 유기되는 vaginal mucosa의 epidermization이 testosterone의 투여에 의해 급속히 소진됨을 Currier 일파가 증명하였고 estrogen에 의해 유발된 웅백서 부속성선의 조직변성이 androgen의 동시투여의 소실됨이 homone에 의해 유발된 neoplastic에 대해 유효하리하는 것은 백명한 일이고 이러한 사실은 현재 실시로 허다히 이용되고 있는 것이다.

The climacterium is that phase in the aging precess during which a woman passes from the reproductive to the non-reporductive stage. The signals, such as hot flashes, vaso-motoric disturbances, perspiration, stiff shoulders, emotinal symptoms, are refered to as climacteric disturbances. Treatment of climacteric symptoms centers around estrogen replacement and transfuilizers, but there are many problems to be solved to use these hormones/drugs as far as dossage, duration and complications are concerned. The care of women during the climacteric years should provide relief of distressing symptoms with as high a degree of safety as possible. From this view point, we used red ginseng powder to those patients with high menopausal index successfully. We studied its mechanism of action and proved that red ginseng improved the micro-circulation system via improvement of erythrocyte reformability which enhanced sex steroidgensis consequently.

The contraception practice rate in Korea has steadily increased from 9% in 1964 to 72% in 1987. Accordingly, natural increase rate of population declined from 28.4 per 1,000 in 1964 to 12.4 per 1,000 in 1987. Notably in recent years, the acceptance of surgical contraception services has sharply increased in this country. Now the author analyzes various factors influencing successful vasectomy and vasovasostomy based on his experience in performing more than 8,000 vasectomies and 1,000 vasovasostomies during the past 25 years. These various factors consist of preoperative screening interview, surgical vasectomy technique, vas irrigation technique, open-ended vasectomy, complications from vasectomy, sperm granuloma formation, spermatogenesis and steroidogenesis after vasectomy, immunological consequences after vasectomy, prostatic diseases and vasectomy, late post-vasectomy syndrome, psychological effects after vasectomy, and success rates of vasovasostomy. Besides, the author makes more comments on the results of the clinical trials on new approaches to reversible vas occlusion technique with a new device of Intravasal Thread and to reversible suppression of spermatogenesis with long-acting sex hormones.

The ultimate function of the endometrium is to allow the implantation of a blastocyst and to support pregnancy. Cycles of tissue remodeling ensure that the endometrium is in a receptive state during the putative 'implantation window', the few days of each menstrual cycle when an appropriately developed blastocyst may be available to implant in the uterus. A successful pregnancy requires strict temporal regulation of maternal immune function to accommodate a semi-allogeneic embryo. To preparing immunological tolerance at the onset of implantation, tight temporal regulations are required between the immune and endocrine networks. This review will discuss about the action of steroid hormones on the human endometrium and particularly their role in regulating the inflammatory processes associated with endometrial receptivity.

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of pediatric liver disease. Similar to NAFLD in adults, NAFLD in children is associated with obesity and insulin resistance and requires liver histology for diagnosis and staging. However, significant histological differences exist between adult and pediatric NAFLD. The rise in childhood obesity has been accompanied by an increase in pediatric NAFLD. Age, gender and race/ethnicity are significant determinants of risk, and sex hormones, insulin sensitivity and adipocytokines are implicated in the pathogenesis of pediatric NAFLD. There is no consensus for treatment of NAFLD, however, data suggest that diet, exercise and some pharmacological therapies may be of benefit. To evaluate and effectively treat pediatric NAFLD, the pathophysiology and natural history of the disease should be clarified and non-invasive methods for screening, diagnosis, and longitudinal assessment developed.

To make index on therapy or releasing from dairy holstein cows of reproductive disorder, the levels of serological sex hormones and total ALP, GOT, GPT, and serum protein were measured. The results obtained through the experiments are summarized as follows ; 1. The levels of FSH and estradiol in reproductive disorder group were significantly higher and lower than those in pregnant group and control group, respectively. (p<0.05) 2. The level of prolactin was showed mild difference in three groups and that of progesterone was reasonably higher in pregnant group with significance (p<0.05). 3. The activity of GPT was significantly higher and that of GOT was showed higher In reproductive disorder group, respectively ( p<0.05) 4. The level of total ALP was higher in reproductive disorder group, however no difference was showed between pregnant and control group. 5. The level of serum protein was followed as control, pregnant, and reproductive disorder with insignificance.
