성선자극호르몬 분비호르몬은 시상하부에서 분비되며, 포유동물의 생식에 중추적인 역할을 담당한다. 골든 햄스터는 계절적으로 번식하는 포유동물이며, 생식 활동은 광주기(하루 중 낮의 길이)에 의해 결정된다. 장주기(12.5 시간 이상의 빛)는 생식 능력을 유지시키지만, 단주기(12시간 이하의 빛)는 생식 기능을 억제한다. 성선자극호르몬 분비호르몬과 광주기의 상호 관계를 자세히 조사하기 위하여 랫트 성선자극호르몬 분비호르몬 cDNA를 포함하는 벡터를 여러 농도로 골든 햄스터의 수컷에 주입하고 단주기에 유지하여 생식 활동을 개별적으로 조사하였다. 벡터를 고농도로 처리한 그룹의 골든 햄스터는 기타 실험 그룹에 비해 정소 퇴화가 의미있게(P<0.05) 가속되었다. GnRH의 맥동적 분비가 생식 능력을 유지하는 관점에서 보면, GnRH-cDNA를 포함하는 벡터는 GnRH를 일정하게 고농도로 분비했다고 사료된다. 이 결과는 GnRH를 포함하는 벡터가 뇌하수체 전엽을 desensitization시켜 정소 퇴화를 가속시켰음을 암시한다.

Cynomorium songaricum (CS) has been used in traditional Korean medicine in treating male impotence and sexual dysfunction. We investigated the effects of aqueous CS extract on the reproductive activity of golden hamsters whose spermatogenetic capacity is active in summer and inactive in winter. The animals were divided into 5 groups: long photoperiod (LP) control, short photoperiod (SP) control, and SP animals treated with low, middle, or high concentrations of CS. The animals were orally ingested with low (0.5 g/kg), middle (1.0 g/kg), or high (2.5 g/kg) concentrations of the aqueous extracts for 8 weeks on the daily basis. The control animals received the vehicle. As results, the LP control animals showed active testicular function but SP control animals displayed remarkably reduced testicular weights. The outcomes of the reproductive activity from low and middle concentrations of CS treatments were identical and marked as low dose. The consequences were a partial blocking of regressing activity by SP. On the other hand, the animals treated with high dose of CS extract showed remarkable significance in comparison to the SP control, indicative of a complete blocking effect of the CS on the regressing testes by SP. There were a dose-dependent effects of the CS on the sexual function. These results suggest that the CS extract promotes the male fertility by strengthening the spermatogenesis in the golden hamsters.

This study investigated the effects of recombinant eel gonadotropin hormone (rJeGTH) produced in silkworms, with and without a carboxyl-terminal peptide from equine chorionic gonadotropin (eCG), on the induction of sexual maturation in female eels Anguilla japonica. Experiments were conducted both in vivo and in vitro. In in vitro trials, germinal vesicle breakdown (GVBD) induction did not significantly differ between rJeFSH and $rJeFSH{\cdot}eCG$ treatments and the control group. However, previous studies did find that rJeLH and $rJeLH{\cdot}eCG$ treatments induced GVBD in female eels. Our in vitro exploration of $estradiol-17{\beta}$ ($E_2$) levels in immature ovarian tissues revealed significantly higher $E_2$ levels in the group treated with $rJeFSH{\cdot}eCG$ $1{\mu}g/mL$ than in the control group. In contrast, the in vivo experiments showed no effect of recombinant hormones on the sexual maturation of feminized eels. Previous studies and our own in vitro results have clearly shown that rJeGTH and $rJeGTH{\cdot}eCG$ have a positive effect on the sexual maturation of feminized eels. To develop the activity of rJeGTH in vivo, further studies should confirm circulation time and activity of these hormones in eels' bloodstream, modify the structure of the recombinant gene, and implement additional glycosylation.

Purpose: The purpose of this study was to analyze the effect of emergency contraceptive pill on adolescent sexuality and contraceptive behaviors through a meta - analysis of intervention studies on advance provision of emergency contraceptives. This study aimed to provide objective data on the transition of general medicines to be discussed in relation to the reclassification of emergency contraceptive pills. Methods: Using electronic database, 1,820 studies written in Korean or English without limitation of the year were reviewed and for analysis, 5 studies were selected, in which emergency contraceptives were provided to adolescents. Results: The advance provision of emergency contraceptives has increased their use and shortened the time it takes to take contraceptive pills after unprotected sex. There was no change in the frequency of engaging in sexual intercourse and unprotected sex or in existing contraceptive behavior, pregnancy rates decreased, but there was no increase in sexually transmitted infection. Conclusion: The results of this study provide objective grounds for the reclassification of emergency contraceptive pills and propose effective interventional programs on contraceptive education, such as on efficacy and side effects of the contraceptive drug and its proper use among the youth who engage in sexual activity, to improve their reproductive health.

The study is to reveal what the married women has experienced while they were on the contraception. Data were gathered for four mothers beginning on October, 1996. Interviewees were 22 women. Data were analyzed by Colaizz's phenomenological data analysis method. Three basic structures of contraception experience were derived. Those are 'Conflict in choosing contraceptive methods', 'Dilemmar in sexual relationship', and 'Responsibility concerning contraception'. Contraception was a major task of the married women, and they difficulties, because sexual relation was usually initiated by husband and contraception by husband was negatively perceived in Korea culture. Conflict were caused by inavailability of information, side effects of contraceptive methods, and limitation of the contraceptive methods. Interviewees perceived that responsibility of contraception was on them, but they expressed feeling of anger against they burden by contraception. Most interviewees took initiation of contraception to keep their body healthy. Some of the interviewees got husband's cooperation through negotiation and shared responsibility with husband. Suggestions were as follows ; (1) Sex education, especially on communication about sex, is necessary to the married women. (2) Informations on contraception should be provided in the private environment. (3) Studies on husband's contraception experience are required to promote husband's cooperation.

Even though the rate of infection of HIV is very low compared to other countries, data show a steady rise in HIV infection rates among young people in South Korea. A peer education program was provided to prevent the incidence of AIDS in young people. The program used peer leaders to provide AIDS related information and counseling for middle school students. Peer leaders received special training in AIDS related education and counseling to assist their friends. Peer leaders worked with their mends in one-to-one or small group settings. A pretest-posttest control design (six months after intervention) was used to evaluate the effects of the peer education program for prevention of AIDS. A post-intervention survey found that do you mean six months after the program or after six months of programs of peer program activities, the experimental groups(groups with peer educators) showed better knowledge, more positive attitudes, and less sexual activity when compared to control groups of non-participants(groups without peer educators). Peer leaders showed significant gains in knowledge about HIV transmission, more positive attitudes and self-efficacy not to engage in high-risk behaviors. Peer education was an effective tool for increasing knowledge, improving attitudes and self-efficacy, and encouraging appropriate behavior change.

본 연구는 아동·청소년기 근친 성폭력 피해자들이 사건 이후 겪게 되는 다양한 심리적 변화와 현실을 그들의 목소리로 전달하여 새로운 시각을 제공해야 할 필요성과 상담을 통해 삶에 적응하기 위해 노력하는 개인적인 삶의 경험을 현상학적인 접근을 통해서 이해하고 기록하였다. 현상학적 방법론을 통한 분석 결과는 다음과 같다. 첫째, 참여자들은 부모의 정서적인 방치와 가족구성원의 폭력적 행동과 위협, 침묵을 강요하는 과정을 통해 대인관계에 대한 불신감과 낮은 자존감이 형성 되었고 일상생활에서 지속적인 어려움을 겪게 되었다. 둘째, 성폭력 사건에 의한 고통과 후유증은 사건이 알려지는 것에 대한 두려움과 자신에 대한 부정적인 생각, 대인관계의 어려움으로 나타나 현실부적응과 사회활동 회피를 반복하면서 역할의 갈등을 경험하게 하였다. 셋째, 아동·청소년기 근친 성폭력의 후유증은 PTSD를 통해 극단적으로 드러났다. PTSD의 경험은 참여자가 정신과에서 처방받은 약물이나 알코올과 같은 물질에 의존하고 환청과 환각, 망상의 경험으로 외부활동을 더욱 기피하게 하는 요소가 되었다. 넷째, 적응 과정을 통한 변화는 사건에 대한 직면과 분리, 삶에 대한 새로운 시선이다. 적응 프로그램을 진행하면서 과거의 상처로 인해 표현하지 못한 말과 감정을 표현하고, 자신의 삶을 살아가기 위한 목표를 세우고 앞으로 나아가려고 했다. 현실에서의 극복 경험은 참여자에게 자기존중감과 삶에 대한 자신의 능력을 신뢰하는 자기효능감, 건강한 자기조절능력에 대한 믿음을 향상시켰다. 본 연구는 개인의 삶에서 근친 성폭력 트라우마가 새로운 일상의 위기를 통해 재경험되고 각 과정마다 새로운 적응 과정을 반복하는 모델을 제시하는데 의의를 둔다.

Women's clothes which represent feminity was one of the female oppression polices in the society of phallocentric sexual order. Many women were eager to good-looking as a comouflage for inferiority of their own sex which was the theory of fashion of Freud. He insist that it's the driving force for women fashion. Thight-lacing corset high heel and foot-binding which was made for men's pleasure limited women's social activity and unfortunately recycled. Such clothes or shoes makes women belong to men's power but its also one of the self controls for women. The materialization and sex objects of women was due to fashion which encouraged by men. Many facts of fetish gradually emerged I fashion and fetishism itself is no more than sexual perversion or low class sex culture. This paper is focused on relationship between fetishism and fashion which approaching based the feminism. We investigated how human ambivalence which persuit both modesty and fetishism is manifested in clothes. We also compared modern fetish fashion with corset and shoes which are sterotypes of classic fetishism

Many transgenic mice expressing human growth hormone gene were infertile. To investigate the infertility of these transfenic mice, it was looked into the estrus cycle and sexual behaviour and also tested through in vitro fertilization whether the germ cells of these mice normal or not. The infertile female transgenic mice were mated to the fertile males of ICR strain, but in almost all of them the vaginal plugs were not detected and their estrus cycles by vaginal smear were almost irregular which kept up estrus or diestrus stage. Many male transgenic mice did not have the ability of sexual behaviour. Therefore the viability of germ cells in infertile male transgenic mice was investigated by in vitro fertilization, but the sperm were normally fertilized with the eggs and the transgene of parent was passed on to the progeny. These results consequently suggest that the infertility of transgenic mice experssing human growth hormone gene may be due to the physiological activity of human growth hormone, not germ cells.

The purpose of this study is to examine the prevalence and correlates of three types of risk-taking behavior among high school students in Korea in a cross-sectional national sample. A sample of 636 male and 622 female high school students is analyzed using descriptive statistics and logistic regression. Three types of risk-taking behavior are examined: drinking alcohol, smoking, and premarital sex. The results are as follows: Forty-three percent of students in the sample have ever drunk alcohol, 32% have ever smoked, 11% have experience premarital sex. Risk-taking behavior is more prevalent among boys than among girls. Boys and girls in Seoul are much more likely to have experienced three types of risk-taking behavior. Not having two parents in the family and having lived away from immediate family increase the likelihood of some risk-taking behavior. Students who have a friend with premarital sexual experience are much more likely to have experienced premarital sex themselves. Among sexually active students, having multiple sexual partners is common and prevalence of condom use is low. Reproductive health education at school has no effect on students' sexual behavior. The prevalence of risk-taking behavior among adolescent in Korea is likely to rise in the future. Substantial proportion of adolescents are exposed to the risks of STDs and substantial proportion of adolescent girls risk premarital pregnancy. Current health education programs are inadequate in protecting students from risk-taking behavior. Students whose families do not include both parents and students who live away from their immediate families need special programs to protect them from risk-taking behavior.
