The purpose of this study was to investigate the factor of feminization in men's fashion according to Sex Role Stereotype of 20's$\sim$30's mens. The investigators surveyed 260 men who aged twenties and thirties in pusan. For data analysis, we used Chi-Square Test, Factor Analysis, Reliability Analysis, T-test and ANOVA along with SPSS 12.0 package. The results of this study were as followings: First, the result of sex role stereotype according to vital statistics was different with age, scholarship, job, and employer. Androginy type and Undiffer type highly showed most variable. That showed the change of Sex Role Stereotype. Second, the result of the factor of feminization in men's fashion according to Sex Role Stereotype was identified as 'pursuit of fashion,' 'pursuit of sense,' 'feminity,' 'secession of sex role.' Third, the result of the factor of feminization in men's fashion according to the vital statistics was different with scholarship, job, and employer. Forth, the factor of feminization in men's fashion according to sex role stereotype was different with 'pursuit of fashion,' 'pursuit of sense,' 'secession of sex role.' Especially, 'pursuit of fashion' and 'pursuit of sense' was importantly understood with the factor of feminization in men's fashion in Androginy type.

We investigated the androgenic effects of 11-ketotestosterone (11-KT) on gonadal sex reversal and spermatogenesis in honeycomb grouper Epinephelus merra by method of gonadal biopsy. 11-KT was injected intramuscularly at a concentration of 1 and $10{\mu}g$ body weight. The proportion of cross sectional area of the gonad occupied by each germ cell type was measured and compared pre- and post-injection group. During the sex change phase, the distribution ratio of oocytes was decreased in all fish of 11-KT treatment group while the distribution ratio of spermatocytes was increased than pre-injection group. In male phase, all fish of 11-KT treatment group shown the increased distribution ratio of spermatocytes, but the distribution ratio of spermatozoa was decreased than pre-injection group. The present results suggest that 11-KT can stimulate degeneration of oocytes, proliferation of spermatocytes and spermiation in honeycomb grouper.

Purpose: This study is an integrative review to analyze articles about sex education for school age children in Korean journals. This study explored the year, methods, major variables and key findings of previous studies. Methods: Five electronic databases and eleven journals of nursing in Korean language were searched to find studies done until 2017. 75 papers published from 1995 to 2017 were selected (43 were survey studies and 32 were intervention studies). Results: Among the intervention studies, there was no Randomized Controlled Trial (RCT) study. Most intervention studies were conducted to change sexual knowledge and sexual attitudes. Among the survey studies, Q methodology and content analysis were used. The subjects' sexual knowledge and sexual consciousness were measured low in some studies. The sex education for school age children was composed of elementary school students' perception, understanding and needs related to sex. In addition, sex education was carried out to improve students' informational aspects such as sexual knowledge, prevention of sexual violence and secondary sexual character as well as emotional aspects such as sexual attitude. However, research on sexual consciousness, sexual values and sexual identity was insufficient. Conclusion: In order to develop an effective sex education program for school age children, it is necessary to consider the degree of their perception, understanding and needs and reflect both the social and cultural aspects as well as the informational and emotional aspects.

This study investigated effect to injure cerebrovascular accident patients who divided cerebral hemorrhage and cerebral infarction of sex the distinct on as a result of body composition. cerebral infarction patients of cerebrovascular accidents were observed the higher ratio than cerebrovascular hemorrhage patients. Experimental group were sixteen subjects who had received. we used assessment instruments such as in body to assess body composition. The result were as follows; 1. Change in body composition according to the come of onset, there were not differenced significantly between two groups. 2. Change in body composition according to the sex, the soft lean mass were differenced significantly(p<.05). but the other variations were not differenced significantly between two groups. 3. Change in body composition according to the region of paralysis, the soft lean mass were differenced significantly(p<.05). but the other variations were not differenced significantly between two groups.

We examined the effects of 17${\alpha}$-methyltestosterone (MT) on growth and induced sex change in the longtooth grouper Epinephelus bruneus. The growth rate for body weight (GRW) and specific growth rate (SGR) of the group injected with MT over 8 weeks were significantly higher than those of the sham-injected control group, the group injected over 4 weeks, and the control group. Of the orally administrated groups, the GRWs of the control group and the group given 1 kg of feed with 2.0 mg of MT were highest and did not significantly differ from one another. For SGR, the treatment groups differed significantly, and the SGR of the control group was higher than those of the other groups (P<0.05). The condition factor (CF) of the group injected over 4 weeks was higher than those injected over 8 weeks, the sham-injected control group over 8 weeks, and the control group. The CF did not significantly differ between the sham-injected control group over 8 weeks and the injected group over 8 weeks, but these two groups differed from the control group (P<0.05). The CFs of the groups given 1 kg of feed with 0.5, 1.0, and 2.0 mg of MT were significantly higher than that of the control group (P<0.05). The feed efficiency ratio was not significantly affected by MT administration. Most of the experimental groups receiving MT developed many unidentified germ cell cysts and perinucleolus oocytes, although neither spermazoa cells nor sex-changed males were observed in any of the treatments.

A sex-linked random amplified polymorphic DNA (RAPD) marker was identified from Asparagus officinalis L. and was converted into a sequence-characterized amplified regions (SCAR) marker for the large-scale screening of male and female plants. A total of 100 arbitrary decamer oligonucleotide primers were used for the RAPD analysis. Among them, the primer UBC347 amplified one female-specific 400 base pair DNA. Subsequently, the amplified RAPD fragment was cloned and sequenced. The fragment was abundant in AT and shared sequence homology with retrotransposon elements. On the basis of the sequence obtained, a pair of SCAR primer was designed. The amplification product, named F400, was the same size as the respective RAPD fragment from which it was derived. The F400 SCAR marker resulted to be female-specific in the three asparagus varieties tested in this study. This SCAR marker can be used for an early and rapid identification of female and male plants during breeding programs of asparagus.

The purpose of this paper is to deeply understand the transitional concept of gender expressed in the later 20th century fashion through analyzing of various literature. Gender is constructed in the context of social and culture different than sex which is inherent difference between man and women. Thus the concept of gender can be changed according to change of social and culture. There are imposing changes in gender since 60's owing to various factors; namely, feminism, subculture, deconstruction, development of technology, market economy, changing sex roles, etc. Especially in the 60's to 70's, as radical changes were took place, gender became vague more and more. Finally these days there is no fixed gender. In terms of meaning, there may be a number of genders-since there are as many meanings of sex as there are people who have thought about it. That is, sex is, gender means. Sex exists in itself, and is sublimely indifferent to what humans think of it, However gender is all the meanings we assign to sex. In accordance with this phenomena, people don't mind their sexes with appearance. There is only different disposition and taste.

Guppy fry were treated for the first 40 days of life with 0, 20, 40, 60 & 100$\mu\textrm{g}$ of estradiol per gram of food in order to change the sex of normal males to functional females(genetic male). The present investigation deals with the effects of steroid hormones, such as $\beta$-estradiol and testosterone, on the sex differentiation in guppy and tilapia. The results obtained were summarized as follows. 1. In B (20$\mu\textrm{g}$/g diet) group 17$\beta$-estradiol-treated, 67.8% of male offsprings were produced. 2. In D (60$\mu\textrm{g}$/g diet) group 17$\beta$-treated, 67% of female offsprings were produced. 3. B, D groups of genetic male brooders had significantly different effects (P<0.01) upon sex ratios of their progeny. 4. This strongly indicates that sex direction has been achieved and that the male is the heterogametic sex. 5. The group that produced the highest percentage of male offspring(male percentage of observed number to expected number was 91%) contained only full-sibling male brooders to the sex-reversed female brooders. 6. After 7 months following treatment, the sex-reversed males had ovarian portion in the anterior region and a testicular portion in the posterior region of the same intersexual gonad, respectively. 7. At 7 months after treatment, the ovareis revealed a complete arrest of the ovarian formation, and appearances of spermatogenetic cell cysts among surviving auxocytes. 8. In most of sex-reversed fish, anterior portion of test is was devoid of sperm ducts including the seminal vesicle and vas deferens. 9. The male transferrin showed two strong bands, while the female transferrin showed a single weak band. 10. One of the two bands of male transferrin showed the same mobility with band of female transferrin.
