Many aspergilli that belongs to ascomycetes have sexuality. In a homothallic or self-fertile fungus, a number of fruiting bodies or cleistothecia are formed in a thallus grown from a single haploid conidia or ascospores. Genome-sequencing project revealed that two mating genes (MAT) encoding the regulatory proteins that are necessary for controlling partner recognition in heterothallic fungi were conserved in most aspergilli. The MAT gene products in some self-fertile species were not required for recognition of mating partner at pheromone-signaling stage but required at later stages of sexual development. Various environmental factors such as nutritional status, culture conditions and several stresses, influence the decision or progression of sexual reproduction. A large number of genes are expected to be involved in sexual development of Emericella nidulans (anamorph: Aspergillus nidulans), a genetic and biological model organism in aspergilli. The sexual development process can be grouped into several development stages, including the decision of sexual reproductive cycle, mating process, growth of fruiting body, karyogamy followed by meiosis, and sporulation process. Complicated regulatory networks, such as signal transduction pathways and gene expression controls, may work in each stage and stage-to-stage linkages. In this review, the components joining in the regulatory pathways of sexual development, although they constitute only a small part of the whole regulatory networks, are briefly mentioned. Some of them control sexual development positively and some do negatively. Regarding the difficulties for studying sexual differentiation compare to asexual one, recent progresses in molecular genetics of E. nidulans enlarge the boundaries of understanding sexual development in the non-fertile species as well as in fertile fungi.

Cervical cancer is a serious public health problem in Thailand. We investigated possible risk factors for cervical cancer including HPV infection, p53 polymorphism, smoking and reproductive history among women in Northeast Thailand using a case control study with 177 cases and age-matched controls. Among the HPV carriers, a significantly increased risk for cervical cancer with an OR of 36.97(p<0.001) and an adjusted OR of 38.07(p<0.001) were observed. Early age at first sexual exposure, and multiple sexual partners increased the risk of cervical cancer with ORs ranging between 1.73-2.78(p<0.05). The interval between menarche and first sexual intercourse <6 years resulted in a significant increase in the risk for cervical cancer with ORs ranging between 3.32-4.09 and the respective adjusted OR range for the 4-5 and 2-3 year-old groups were 4.09 and 2.92. A higher risk was observed among subjects whose partner had smoking habits, whether currently or formerly; with respective ORs of 3.36(P<0.001) and 2.17(p<0.05); and respective adjusted ORs of 2.90(p<0.05) and 3.55(p<0.05). Other smoking characteristics of the partners including smoking duration ${\geq}20$ years, number of cigarettes smokes ${\geq}20$ pack-years and exposure time of the subject to passive smoking ${\geq}5$ hrs per day were found to be statistically significant risks for cervical cancer with adjusted ORs of 3.75, 4.04 and 11.8, respectively. Our data suggest that the risk of cervical cancer in Thai women is substantially associated with smoking characteristics of the partner(s), the interval between menarche and first sexual intercourse as well as some other aspects of sexual behavior.

The main purpose of the study is to identify the perception, as well as the prejudices, of sexuality of the elderly and their sexual life. Older men and women aged 66-80 (N=17) who are married, healthy, and living in communities were interviewed regarding ADL, present and past sexual practices, prejudices on elderly sexuality, and obstacles to sexual life. The findings of this study are as follows: First, the old perceived that sexuality even in old age is an important part of life. However, they were also prejudiced about sexual intimacy in old age. Second, although an increase in age is correlated with a decrease in sexual activity, a number of older men and women continue to have active sexual life and they are satisfied with it as ever. This indicates a duality in the way the elderly perceive sexuality. Third, health status, partner's responsiveness, and environmental problems are prominent obstacles to sexual life. The study revealed that late-life sexuality must be conceived as a complex bio-psycho-social phenomenon. Consequently, it is important to hold sexual education programs for the young and the old.

Objectives: The study was designed to assess the trends of the incidence of HIV among young people and their sexual risk-taking behaviors by gender in Korean college students. Methods: The cross-sectional study was used from college students from selected 60 among 208 4-year colleges and universities in 9 provinces and Seoul. A self-reported anonymous questionnaire administered and completed to a national representative sample of 4-year college students from May 15th to June 14th in 2003. We analyzed 2,385 cases. The overall response rate was 82.0%. Results: After controlling age effects, male students were more likely to be sexually experienced than female students(40.0% vs. 8.1%), OR=5.5, p<.000. The proportions of 19 years and before reported for initiation of sexual intercourse were 18.6% for males and 3.2% for females. Males reported significantly younger ages than females at initiation of sexual intercourse(p<.01). Only 14.8% of current sexually active subjects reported consistent use of contraceptive methods. After controlling age effects, male students reported a higher proportion of sexually experienced respondents with one or more casual partners(excluding a formal partner) during the last 12 months than women(38.8% vs. 22.2%), OR=2.2, p<. 05. Conclusion : This study can conclude that although males students initiate sex earlier and have higher percentage of sexual experience, the percentage of sexually experience female students has risen rapidly compared to the past. This data revealed a number of young people were at risk for HIV infection. Both genders are equally likely to have engaged in inconsistent condom use even though when they have a sex with an unknown partner. These findings suggest that practical sex education focused on using condom use should have been included in the school curricular. Educational and community interventions need to prevent sex-related problems.

This study confirms and describes the meaning of the true experience on sexual perception of female college students as it is. Thus this study, revealing the structure of the meaning, tried to use phenomenal study tool as qualitative research design in order to seek nursing intervention for them. The method of data collection of this study was achieved February, 2000$\sim$August, 2000 through systematic interview, participation and observation from a focus group. The number of each focus group was 3 to 4, and the study analyzed with Giorgi method after selecting total 3 groups with 10 to saturate data, considering of the closeness among group members. The results are as follow; 1) Feeling psychological uneasy : feeling special mood, mysterious thing, tense thing, curious thing, concealing thing 2) Being to someone : receiving unilaterally, giving ahead, attracting attention, being to, being selected unilaterally 3) Feeling like to do together : relying, contacting, being together 4) Accepting another one's self : understanding the partner, taking responsibility for each other, enduring, trusting each other 5) Trying to be best to the partner : physically being pure, mentally being pure, being only one person to the partner, being open to each other, feeling free 6) Harmonizing conditions with conditions : considering appearance, one's family, economic support and so on 7) Making a love without premise of marriage : making a difference between marriage and love 8) Being a difference between men and women : being a different position, being shameful (because of not having a boyfriend), indecent thing 9) Being for a new life : conceiving a new life 10) Being able to have body touch : being able to kiss, being able to sleep together, being able to touch body 11) Being able to make homosexual love : being able to do homosexual love From the above results, right sexual education should deliver the value of sex which exists for life. So we need to develop the Korean-typed sexual education, according to the social and cultural background and reasonable demand level of education subjects. Furthermore we should give systematically connected education through the development of sexual education program by a developmental stage on the sex with broad and dynamic features, revealing different shapes each period of life. Since the members' value by culture is very different, reasonable and healthy sexual education cannot be done through a education program from foreign cultures. Consequently, the development of the study and program on sexual perception of Korean female college students suitable for the Korean cultural situation will be done.

In the mathematical model for the transmission dynamics of HIV infection described in previous papers, the population under consideration is assumed to be homogeneous community of homosexual males for which the parameter x represents the constant rate at which individual members of the population acquire new sexual partners. This is a gross oversimplification since it is well known that individuals vary widely in their levels of sexual activity and in this papers the heterogeneous model is modified to allow for this variation. The pattern on the epidemic character of HIV, the causative agent of AIDS, was analysed by heterogeneous-mixing model. The computer simulation was performed using real date.

The purpose of this descriptive study was to assess sexual orientation and Knowledge and attitudes with regards to AIDS in military personnel, and to provide basic data for developing a further sex education program for them. The data were collected in June 2002 on 242 service members of A Branch of the Ground Army located in Chung-Chung Do Region. They responded to a survey questionnaire that consisted of 68 items: 14 items on sexual orientation. 39 items on knowledge about AIDS, and 15 items on attitudes toward AIDS. The data were analyzed using SAS program. The study results are as follows: 1. Sexual orientation of the military personnel 1) In terms of sexual orientaion, harassment and assault, only $26.4\%$ of the subjects responded as, 'know well'. Appropriate awareness of the legal liability was reported by $21.6\%$ of the subjects regarding sexual harassment and $78.1\%$ of the subjects regarding sexual assault. 2) Pre-marital cohabitant was supported by $89.2\%$ of the subjects. 3) The Korean military personnel showed liberal attitudes toward sexuality as $46.4\%$ of them reported having sexual-relationship with the dating partner is acceptable. 4) The attitudes of the most subjects toward homosexuality was found to be unfavorable. 5) Subjects were m the need of appropriate sex education. of which substantial knowledge on sexual intercourse was the most needy area. 2. Knowledge and attitudes toward AIDS of the military personnel 1) The subjects' level of knowledge on AIDS was relatively low, showing the average score of $22.31\pm7.23$ points (range: 0-39 points). The higher level of knowledge was reported by those who had high level of education, father alive. and less number of brothers in their family. 2) The subjects' attitudes toward AIDS was relatively positive. The attitude toward AIDS was also found to be more positive in those who had high level of education and less number of brothers. 3) There was a positive but weak correlation between knowledge and attitude toward AIDS. The study finding showed that the sexual orientaion of the Korean military personnel was moderately positive and liberal. However, their awareness of sexual harassment and assault and AIDS was still found to be low. As Korean enlisted military service men are likely to be in the ages with strong sexual desire, it may be important for them to have appropriate sexual orientation and attitudes toward AIDS. Therefore, it is recommended to develop further practical and sound sex education programs within the military unit in order to meet their education needs as well as to utilize sex education specialists as the instructors of those programs.

Violence against women includes sexual violence, domestic violence, trafficking, etc. It is a serious problem that violates women's rights and basic freedom. In Korea, with the enactment of the laws on sexual violence and domestic violence in the 1990s, counseling centers and protective facilities for the victims began to be established and have been rapidly increasing in number recently. The purpose of this research was to investigate the current status of the counseling services with a focus on their linkage function. 78 out of 109 counselors working in the counseling centers for sexual and domestic violence throughout Korea responded to a mail survey. The questions included the general characteristics of the centers and the counselors, the structural, relationship and process dimensions of linkage function, and the subjective and objective aspects of the degree of linkage. The findings of the analysis highlighted the following problems. First, the counseling centers played limited role in serving the victims of violence due to lack of resources in the service network. Second, the linkage of services existed on a relatively small scale which was mostly based upon informal and unstructured relationship. Third, according to the multivariate analysis, the existence of potential partner agencies, the effort of the line staff to initiate the linkage relationship and mutual cooperation between agencies determined the degree of linkage among services. These findings suggest implications for establishing a more effective system to protect the victims of violence.

Exploring the epidemiological trend of HIV/AIDS is required for making the national AIDS policy. In this study, the trend of HIV/AIDS incidence, rout of transmission and some characteristics of AIDS for the past 11 years in Korea using the reported cases from the national STD screening scheme were reviewed. Based on the results, the trend of main route of transmission according to the year was established by stage and the HIV/AIDS cases in this year was estimated and that to the year 2000 was projected by 'Epimodel' programme. The results were as follows : 1. Of the total infected persons, 76% were in their twenties and thirties, socioeconomically and sexually active age groups. While the transmission by sexual contact overseas was decreasing, the infection through domestic heterosexual and homosexual contact was increasing. 2. In the middle of the 1980's, the infected persons were mainly prostitutes infected through heterosexual contact with the HIV positive foreigner in this county(stage 1). And in the late of the 1980's the main source of infection was the sexual contact overseas and the domestic heterosexual contact(stage 2). Since the early of the 1990's, the infection through the heterosexual contact with non-regular sexual partner in this country has increased rapidly(stage 3), which was the evidence of the possibility of HIV epidemics. After that, it was expected that the infection through the homosexual contacts, the heterosexual contacts with commercial sex workers outside and the non-regular sexual contact inside of this country would increase continuously. In the result, the occurrence of neonatal infection by vertical transmission was expected(stage4). 3. The number of HIV/AIDS was estimated at 572 to 2,313 and the projected number of HIV/AIDS to the you 2000 was around 5,800 including 627 AIDS patients. For the further study on the estimation and projection of HIV/AIDS, it was suggested that the sampling survey on the HIV infection rate in the high risk groups and the sentinel hospital surveillance system should be conducted.

The purpose of this study was to examine the dynamics of psychological and sexual violence in dating among high school students. Subjects consisted of 1,205 male and female adolescents from all parts of the country. 1,092 respondents were included in the final analysis(90.6%). For psychological violence, 13.3%(n=145) reported to have such experiences with a dating partner at least once or more. The most frequently used forms of violence were shouting, insulting language and behaviors, and blaming for a physical appearance. There were no sex differences in frequency of psychological violence between males and females, as an aggressor or a victim. Responses of victims were mostly negotiation and communication, and trying to forget it. For sexual violence, 27.8%(n=303) was found to have such experiences in a dating scence at least once or more. Hugging and kissing, close contact of parts of body, and gazing at parts of body were most frequently used forms. Responses of victims were pretending not to notice it and responding in the same way. There were significantly more male aggressors of sexual violence than females, but no sex difference in the number of victims. Those who reported to have experiences of violence were compared to the counterparts who had no experience in attitudes toward violence between dating partners and married couples, experiences of violence in childhood, school violence, and observations of violence between parents. Those with experience of dating violence reported to have significantly more experiences of violence in childhood and school, and parental violence. Based on the findings of this study, suggestion were made in regard to the need for development of dating violence prevention program for adolescents, and for welfare programs for adolescents in community.
