Thinness has become a symbol for beauty, acceptance and competence for women in our society, and pressure to diet because of this unrealistic standard is one factor reponsible for the increasing incidence of eating disorder. Three hundred fifty college women in the Chonbuk area were surveyed from May to June 1998, to investigate the relationship among body image, eating disorder, dietary intakes, self esteem and sex role identity. This study identified a subgroup of women who were relatively satisfied with their body weight and who did not diet. This group was compared with subgroups of women who were dissatisfied with their bodies and either were or were not restrained eaters. The dissatisfied/dieting women had the highest BMI, binge eating disorder and night eating syndrom, had significantly lower calorie, protein, iron, vitamin B$_1$, and vitamin B$_2$ intake compared with the satisfied/non-dieting women. The dissatisfied /dieting women, who had lower self-esteem compared with the satisfied/non-dieting women, but the frequency of sex role identity was similga among the groups of women. BMI and binge eating disorder were positively correlated(r=0.157, p＜.01), but BMI and self esteem were negatively correlated(r=-0.202, p＜0.01). Especially, binge eating disorder and self esteem were negatively correlated (r=-0.126, p＜0.05).

This study shows trends and age-sex patterns of mortality in Korea, based on adjusted death registration data during 1956∼1980. Description on the data-the types of errors and their methods of adjustment-are presented elsewhere (Kim, 1986). Crude death rates have declined in 20 years to 7.0 in 1976∼1980, almost half the level of 13.0 in 1956∼1960. Mortality of females declined faster than males, especially at older ages. Substantial differences in provincial mortality are observed based on the expectation of life at birth. The difference between the highest and the lowest provinces is 9.2 years for males and 8.3 years for females during 1976∼1980. This study presents two interesting features of age-sex patterns of mortality in Korea. One feature is higher female mortality than males during childhood periods. However, infant mortality is higher for males than for females throughout the period, though the difference is much smaller than is expected from various model life tables. Another feature is the rapid rise in mortality for males after age 40. This pattern is found to be existed throughout the period 1956∼1980. Further studies are recommended to establish its causal linkage to traditional sex role (as main bread winner) and health behavior (smoking and drinking) of males and recent rapid industrialization in Korea.

To monitor the reproductive patterns of endangered orangutan, Time-resolved fluorescence immuno assay (TR-FIA) were used to analyze metabolites of sex hormones in feces. Orangutan had long-term interbirth intervals (amenorrhea) during lactation period in which the secretion of sex hormones was repressed. The concentration of progesterone in the serum of pregnant orangutan was 30fold higher than that in non-pregnant orangutan. However, the concentration of hCG during pregnant period was different from the result of other primates. The present study suggested that age is not the important factor in determining the reproduction capability, because it is rather greatly influenced by the combination of various factors. Tracing metabolites of sex hormones in orangutan feces seems to be provide the effective solution for the infertility in orangutan. This study result shows the basic data in operating conservation project for endangered orangutan.

The purpose of this study is to understand the sex life of men with rectal cancer. Participants were 8 males who were treated with rectal cancer and analyzed semi-structured questionnaire by Downe-Wamboldt's content analysis method(Step 8). As a result of the analysis, three categories and nine subcategories were derived: Physical difficulty, Psychological difficulty, Mutual role difficulty. Thus, men treated with rectal cancer experience physical, psychological, and interrelated difficulties related to sex. This study was meaningful in that it revealed the experience related to sexual experience of men with rectal cancer and could be used as useful data for the development of sex - related programs.

Ginseng has been used in China for at least two millennia and is now popular in over 35 countries. It is one of the world's popular herbs for complementary and alternative medicine and has been shown to have helpful effects on cognition and blood circulation, as well as anti-aging, anti-cancer, and anti-diabetic effects, among many others. The pharmacological activities of ginseng are dependent mainly on ginsenosides. Ginsenosides have a cholesterol-like four trans-ring steroid skeleton with a variety of sugar moieties. Nuclear receptors are one of the most important molecular targets of ginseng, and reports have shown that members of the nuclear receptor superfamily are regulated by a variety of ginsenosides. Here, we review the published literature on the effects of ginseng and its constituents on two main sex steroid hormone receptors: estrogen and androgen receptors. Furthermore, we discuss applications for sex steroid hormone receptor modulation and their therapeutic efficacy.

Purpose: The present study is a descriptive research on the content of sex education conducted at home by the mothers of young children who are attending five kindergartens located in Busan, Korea. This study aims to provide basic materials for systematic sex education at home and in the school. Method: Based on the literature review and prior researches, the writer made a questionnaire consisting of 30 items regarding necessities, contents and difficulties of sex education. The 307 questionnaires were collected out of 480 which were distributed by the kindergarten teachers. Data was analysed with frequency and percentage using the SPSS Win 10.0 Program. The main subjects of the study were mothers in their thirties, who understood the necessity of sex education. However, they were lack of enough sexual knowledge in accordance with the transforming sexual culture and lack of suitable materials. They did not plan to educate their children according to their developmental stages, but just taught them verbally rather than using common materials for the situation. Result Regarding the origin of life that children often asks, mothers did not give a scientific and correct response to satisfy their curiosity about sex, saying that a baby was created after marrying a loved one. While more mothers than the prior research responded correctly to the queries of the path of delivery, some mothers did not. It may cause some children to suppress the questions, which may result a distorted sexual knowledge. That is because mothers understood that sex education was to deliver sexual knowledge, but not realized that sex education was a human education carried out throughout life. Mothers fell short of sexual knowledge, capability, and confidence, comparing with swift social changes and children's capacity. As a result, it is necessary to inspire sexual awareness into mothers and educate them through training. It is also needed to secure a training program similar to a teacher training program. Conclusion: It is essential to develop and to provide evaluation tools as well as proper materials in accordance with the children's developmental stage, so that organic management system among home, education institute and society must lead sex education Further, it is necessary to provide teaching methods and materials to mothers regularly, so that the school and home may conduct sex education together to cope with difficulties.

In mammals, puberty is a process of acquiring reproductive competence, triggering by activation of hypothalamic kisspeptin (KiSS)-gonadotropin releasing hormone (GnRH) neuronal circuit. During peripubertal period, not only the external genitalia but the internal reproductive organs have to be matured in response to the hormonal signals from hypothalamic-pituitary-gonadal (H-P-G) axis. In the present study, we evaluated the maturation of male rat accessory sex organs during the peripubertal period using tissue weight measurement, histological analysis and RT-PCR assay. Male rats were sacrificed at 25, 30, 35, 40, 45, 50, and 70 postnatal days (PND). The rat accessory sex organs exhibited differential growth patterns compared to those of non-reproductive organs. The growth rate of the accessory sex organs were much higher than the those of non-reproductive organs. Also, the growth spurts occurred differentially even among the accessory sex organs; the order of prepubertal organ growth spurts is testis = epididymis > seminal vesicle = prostate. Histological study revealed that the presence of sperms in seminiferous tubules and epididymal ducts at day 50, indicating the puberty onset. The number of duct and the volume of duct in epididymis and prostate were inversely correlated during the experimental period. Our RT-PCR revealed that the levels of hypothalamic GnRH transcript were increased significantly on PND 40, suggesting the activation of hypothalamic GnRH pulse-generator before puberty onset. Studies on the peripubertal male accessory sex organs will provide useful references on the growth regulation mechanism which is differentially regulated during the period in androgen-sensitive organs. The detailed references will render easier development of endocrine disruption assay.

This study was conducted to increase the efficiency of farming practice in rainbow trout, Oncorhynchus mykiss, by sex reversal and chromosome-set manipulation techniques. Induction of sex-reversed gynogenetic diploid rainbow trout males and mass production of all-female rainbow trout by genetic sex reversal was performed. Phenotypic males in the gynogenetic diploid group were induced successfully by dietary administration of 5 mg of 17 alpha-methyltestosterone per kg diet for 82 days. All females were produced by crossing between normal female and sex-reversed gynogenetic diploid male rainbow trout.

Despite the importance of sexual life of the aged, it is almost disregarded due to the Confucius value system and bias. The common people's view on the sex of the aged was clearly demonstrated by their attitude toward a movie entitled "I love it though I might die" which was determined "18 Age over"being awareness of its explicit sexual intercourse and several lied on the discussion. For this reason, the sex of the aged is clandestinely revealed and uses to receive publicity for sexual assault for children, sexual crime, and illegal prostitution in parks. And social atmosphere that prevents open discussion of the sexof the aged increases in the number of suffering aged in reality, and it causes the decrease of life quality of them. In this circumstance, cartoon contents can be perfectly used for sex education for them. Entertainment character and genre character of cartoon contents can deliver the understanding of sex rather voluntarily and easily to the aged and it can be used as a tool to motivate by indirect experience and to enhance efficient understanding.

The sex differentiation of fishes occurs under the control of genetic and various environmental factors. DM-domain containing genes are novel zinc finger transcription factors and play key roles in sex determination. In order to isolate the wrasse DMRT (wDMRT) cDNA from the protogynous wrasse (Halichoeres tenuispinnis), the wrasse testis cDNA library was screened using the $^{32}$ P-labeled PCR products, which were amplified with the degenerate primers from conserved DM-domain regions of several DMRT genes. Among a few positives obtained through screening, the full length wDMRT cDNA of 2.9kb size encoding a predicted 300 amino acid residues was isolated. The sequence analysis exhibited 60%, 43% sequence identity with rainbow trout and tilapia DMRT1, respectively. RT-PCR assay showed that wDMRT was expressed specifically in male testis. Also, wDMRT gene was strongly expressed in May during reproductive season, when the reproductivity of wrasse is most active. This results suggested that wDMRT gene function in testis differentiation The conserved DM-domain regions were amplified using PCR from DMRT genes of several species among Labridae, and their sequences were determined. The sequence of DM-domain region of Halichoeres. tenuispinis was identical to those of Pseudolabrus japonicus, Pteragogus flagellifera, and showed 94% identity with that of Halichoeres poecioptrerus.
