The reproduction of animals is a means to maintain their species. The golden hamsters are seasonal breeders, and their reproduction is regulated by the photoperiod. The shifts of the sexual functions imply the changes of the protein expression, and those are reflected by the proteome. Thus the present study was to examine via two dimensional polyacrylamide gel electrophoresis (2d PAGE), the physiological changes and the alterations of protein expressions in hypothalamus upon the reproductive situation related to the pineal gland. Among the pineal intact animals, the reproductive functions were sustained in animals housed in long photoperiod (LP) but regressed in animals housed in short photoperiod. And those pinealectomized animals showed high sexual activities regardless of photoperiod. Ultimately they were branched into dichotomy, sexually active and inactive animals. Apart from the changes of physiological parameters upon the reproductive conditions, there were obvious differences in proteins extracted from the hypothalamus. The hypothalamus of LP animals presented high levels of enzymes which are involved in the production of energy, glycolysis and Krebs cycle. The increased energy might be related to the GnRH synthesis in hypothalamus and indirectly to the constant cell divisions in spermatogenesis. Taken together, the impacts of the photoperiodic information controlling reproduction could be observed through 2d PAGE. Therefore, the present results suggest the potential of biomarkers collectively to diagnose the fertility and the infertility by way of proteomics in organs with regard to the reproductive system, further could be applied to diagnose various diseases.

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.

According to previous literature, love involves a feeling of emotional bonds, attachment, and commitment to a specific target from a long-term perspective. In contrast, lust is defined as a sexual desire to engage in sexual activities from a short-term perspective. This research investigates the influence of feelings of love or lust on consumers' long-term benefit-seeking and risk-taking behaviors. Study 1 examined whether consumers' long-term benefit-seeking behaviors depend on feelings of love or lust. As a result, consumers who experienced feelings of love were more likely to prefer products that provide long-term benefits (e.g., a hybrid car) than those who experienced feelings of lust. Study 2 investigated consumers' risk-taking behaviors, depending on feelings of love or lust. The results showed that consumers in the lust condition were more willing to take a risk (e.g., a trip to a hazardous area) than those in the love condition. Taken together, this research demonstrates that consumers' long-term benefit-seeking and risk-taking behaviors depend on feelings of love or lust. Practical and theoretical implications are further discussed.

The purpose of this study was to develop a sexuality education program for early adolescents. The overall goals of the program were to not only increase knowledge and skirts, but also to improve the awareness of healthy sex in order to promote premarital abstinence, parent-teen communication and parental awareness of the importance of parental roles and responsibilities in prevention of sexual problems of the early adolescent. The program consisted of six sessions: puberty changes during adolescence, the meaning of sexuality, sexual drives in dating relationships, understanding of the risks associated with early sexual involvement and support for postponing sexual activities, managing and avoiding sexually risky situations, the importance of communications with parents about issues related to sexuality. The program evaluation had three steps: pre-test, immediate post-test and two month follow-up post test. The results showed that the program had a significantly positive effect on the improvement of adolescent's knowledge about sex, and attitudes and behaviors toward sex, particularly in the immediate post-test. At the two month follow-up assessment, the effect of the program still remained strong, though there was a sight and partial reduction which was not statistically significant. Most of the program participants expressed a high level of satisfaction with the program. Parental involvement appeared to be effective as well. Recommendations for further study include: to re-evaluate the curriculum for various other participants. In addition, further study which would compare post-test results of these participants with a comparison group of peers who did not receive the program would be valuable. The author believes that the program can be used in implementing specific subjects (sessions) in new settings, as well as implementing the entire package of the program.

This phenomenological study aims at exploring the role of family in promoting, maintaining, and developing job activities of women with acquired physical disabilities. As a result of in-depth interviews with 8 women with physical disabilities, 6 theme clusters and 14 sub-themes have appeared. Participants have vividly revealed their experiences with regard to the various support and help of their family. They were provided physical, emotional and financial supports which helped at great extent to overcome the anger and loss resulted from the acquired disabilities. Although most of the participants have experienced failure in job finding several times, they have at last succeeded in it by the consistent help of their family. In particular, the support and help given from the family were substantial and specific which promoted maintaining and developing their career. Therefore the participants could obtain more confidence in themselves and this made the participants to speak for themselves. Although the family roles for the job finding and maintaining of the participants are played in various ways which is positive, effective and specific, there remains some significant problems and limitations. Participants expressed their uncomfortableness in opening their most in-depth thinking and emotions to their family. They have also experienced a great deal of difficulties in maintaining job because of the housework load and child bearing work which is mainly regarded by the family members as the woman's(participant's)duties. In addition to this, sexual needs and sexual identity of the participants are neither recognized nor dealt with seriously in family, The participants also mentioned about the inequal relationships and their self-consciousness among family member as well as the lack of career guidance role of the family. Based on these research findings, we have made a number of suggestions to promote the positive roles and overcome the limited roles of the family.

Golden hamsters reproduce in a limited time of a year. Their sexual activities are active in summer but inactive in winter during which day length does not exceed night time and environmental conditions are severe to them. The reproductive activities are determined by the length of light in a day (photoperiod). Melatonin is synthesized and secreted only at night time from the pineal gland. Duration of elevated melatonin is longer in winter than summer, resulting in gonadal regression. The present study aimed at the influences of continuous melatonin treatments impinging on the gonadal function in male golden hamsters. Animals received empty or melatonin-filled capsules for 10 weeks. They were divided into long photoperiod (LP) and short photoperiod (SP). All the animals maintained in LP (either empty or melatonin-filled capsules) showed large testes, implying that melatonin had no effects on testicular functions. Animals housed in SP displayed completely regressed testes. But animals kept in SP and implanted with melatonin capsules exhibited blockage of full regression by SP. These results suggest that constant release of melatonin prohibits the regressing influence of SP.

Objectives: The aim of this study was to explore nursing students' attitudes towards sexually active elderly, and to compare their attitudes with those of non-nursing students. Methods: Study subjects consisted of 118 nursing students, and 134 non-nursing students, recruited from two universities. The data were collected from September to November 2001. Vignettes, which presented hypothetical situations of sexual activities of the elderly (65 years of age, 80 years of age/sexual activity mentioned. non-mentioned), were provided as a research method, as well as the use of a structured questionnaire. Vignettes showed the hypothetical situations by male elder's sexual activity and their age. Respondents were asked to address their thoughts in the questionnaire. Results: 1. Nursing students showed more favorable attitudes toward the elderly than non-nursing students, regardless of the presence of sexual activity of the elderly. 2. No significant difference was found in nursing students' attitudes toward the elderly aged 65 and 80 years, between those who were sexually active and those who were not. These results were the same in non-nursing students. 3. Nursing students showed more favorable attitudes toward the sexually active elders aged 65 years (5.6 1.43), than toward sexually active elders aged 80 years (4.89 1.55). This result was also the same in non-nursing students. 4. The variables significantly affecting attitudes toward the sexually active elderly in nursing students were familiarity with old persons (p=. 02), presence of living grandparents (p=. 05), and the experience of caring for old people (p=. 01). However, in non-nursing students, familiarity with old people was the only significant variable that affected their attitudes toward the sexually active elderly. 5. In nursing students, one variable to predict attitudes toward the sexually active elderly was the experience of caring for old people (p=. 03), accounting for 10% of the total variance. In non-nursing students, familiarity with old people was the only variable to attitudes toward the sexually active elderly (p=. 03), accounting for 3% of the variance for attitude. In both student groups, the variables that predicted attitudes toward the sexually active elderly included college major (p=. 03), school year (p=. 01), familiarity with old people (p=. 02), accounting for 12% of the variance for attitude by these variables. conclusion: Nursing students showed more favorable attitudes toward the sexual activity of elders 65 years of age or over, than non-nursing students. However, both the nursing and non-nursing students showed negative attitudes toward the elderly who were 80 years of age when compared with those 65 years of age. There should be a consideration in nursing education curriculums that university students may have negative attitudes towards sexual activity of the elderly over 80 years of age.

Study Design: Prospective observational study. Purpose: To evaluate the disability domains relevant to Indian patients with low backache and propose a modified disability questionnaire for such patients. Overview of Literature: The Oswestry Disability Index (ODI) is a self-reported measurement tool that measures both pain and functional status and is used for evaluating disability caused by lower backache. Although ODI remains a good tool for disability assessment, from the Indian perspective questions related to weight lifting and sexual activity of ODI are questioned in some of the earlier studies. Activities of daily living in Indian patients vary substantially from those in other populations and include activities like bending forwards, sitting in floor and squatting which are not represented in the ODI. Methods: In this prospective observational study, a seven-step approach was used for the development of a questionnaire. Thirty patients were interviewed to identify the most challenging issue they faced while performing their daily activities (by free listing) and understand how important the questionnaire items were in terms of the standard ODI. Thus, a comprehensive disability questionnaire comprising 14 questions was developed and administered to 88 patients. Both qualitative (interviews) and quantitative methods (to establish the validity, reliability, and correlation with the Visual Analog Scale [VAS] and Rolland Morris disability questionnaire) were used to identify the 10 questions that best addressed the disability domains relevant to Indian patients. Results: According to free listing, four new questions pertaining to bending forward, sitting on the floor, walking on uneven surfaces, and work-related disabilities were included. In the second phase, wherein the questionnaire with 14 items was used, 56.8% patients did not answer the questions related to sexual activity, whereas 23.8% did not answer those related to walking on uneven surfaces. The modified questionnaire demonstrated good internal consistency (Cronbach's alpha=0.892) and correlation with the Rolland Morris questionnaire (Cronbach's alpha=0.850, p>0.05), as well as with the VAS score for disability (Cronbach's alpha=0.712, p>0.05) and pain (Cronbach's alpha=0.625, p>0.05). Conclusions: A modified disability questionnaire that was designed by adding two questions related to bending forward and work status and removing questions related to sexual activity and weight lifting or traveling (depending on the occupation) can help evaluate disability caused by back pain in Indian population.

The purpose of this survey, in which 2754 students from 35 middle schools from Taegu city participated, was to identify the degree and the relationship of sexual knowledge, sexual attitude and need for sex education. This information will provide useful data, and promote a more systematic, desirable and practical sex education. The data was collected from September 1 to November 8, 1997. Data was analyzed using the statistical computer package, SPSS to manipulate the data along with percentage, mean, $X^2$-test. t-test, F-test and Pearson correlation coefficient. The results from this study were summarized as follows: 1. The mean score of sex related knowledge showed significant differences between boys and girls in general knowledge(boys: 10.85 girls: 11.71, p=0.000), in the area of physical development(boys : 5.29 girls: 5.72, p=0.000), pregnancy & physiology (boys: 3.23 girls: 3.57, p=0.000) and venereal disease (boys: 2.33 girls: 2.42, p=0.000). 2. The mean score of sex related attitudes showed a significant differences between boys and girls on the whole(boys : 57.68 girls: 58.92, p=0.000), in the area of psychological differences of the other sex (boy: 26.13, girls: 28.08, p=0.000), and sexual delinquency and its prevention(boy: 14.28, girls: 13.68, p=0.000). However, in the area of other sex friendships (boy: 17.28, girls: 17.16, p=0.274). There were no significant differences between boys and girls. 3. Those who had a higher sex related knowledge score showed more positive attitudes towards sex, but was of no statistical significance(r= 0.312, p=0.000). 4. The majority of subjects wanted to learn about friendship with the other sex(40.1%), about physical and psychological differences in adolescence(24.0%), about prevention of sexual violence(15.0%), about pregnancy and delivery (7.5%), about venereal disease and medical cures(7.3%), about contraception methods (4.3%), as well as other aspects of sexual knowledge (1.8%), 5. The mean score of sex related knowledge generally was higher when one paid a lot of attention to health (F= 3. 148, p=0.014), when one's father was alive(t=3.930, p=0.000), and when one's mother was alive(t=2.807, p=0.005), Hobby activities also showed a significant difference(F=9.092, p=0.000). The mean score of sex related knowledge generally according higher when one had sex education(F=9.470, p=0.000), when one obtained sexual knowledges from a teacher (F = 5. 742, p=0.000), and when one had middle grade problems with sex(F=13.58 4, p=0.000). 6. The mean score of sex related attitudes generally showed significant differences when re ligion(F=2.691, p=0.03), hobbies (F= 3.499, p= 0.002) were considered. Those who had a father also had higher scores(t=2.538, p= 0.011). The mean score of sex related attitudes generally with respect to a subject's sex was higher when one had sex education(t=5.338, p= 0.000), when one had high grade problems with sex(F=6.023, p=0.002), and when one had the experience of friendship with the other sex(t= 8.106, p=0.000), The following suggestions are based on the above results, 1. Systematic sex education must be performed in middle schools in order to establish responsible attitudes toward sex, 2. Sexual knowledge, attitude, and general sex education classes must be performed seperately for early, middle, and late adolescents, In other words sex education programs are needed for each adolescent development stage.
