농촌 여자고등학생들의 성 관련 지식과 태도에 미치는 성교육의 단기 및 중기 효과를 평가하기 위해 2개 고등학교 여학생 119명을 대상으로 150분에 걸쳐 성교육을 실시 한 후 교육 실시전과 실시 후 1개월과 6개월에 각각 l회씩 설문조사를 실시하였다. 에이즈와 관련된 지식의 수준은 교육 전 8.46점에서 교육 1개월 후에 11.90, 6개월 후에는 11.87로 교육 후 상당기간이 경과해도 지식의 수준은 유지하였으며, 사랑하는 사람과는 혼전에 성 관계를 가져도 좋고, 인공유산은 죄를 짓는 것이라는 것 그리고 미혼모, 강간 혹은 질병으로 인해 부득이 하게 인공유산을 받아야 하는 경우를 찬성하는 학생의 비율이 성교육 후에 증가하였다. 고등학생 시절에 이성간에 교제를 하는 것은 긍정적이다라는 생각은 교육 전에도 83.2%로 매우 높았으며 교육 1개월 후와 6개월 후에도 각각 83.9%와 84.9%로 매우 높은 수준을 유지하였으나 중학생 시절에 이성교제를 하는 것에 대해서는 다소 부정적인 의견을 나타내었다. 에이즈에 대한 태도는 성교육 후에 긍정적이며 적극적으로 변화하였으며 특히, 환자를 인간적으로 대하고, 공개적으로 관리해야 한다는 생각이 증가하였다. 결론적으로 성교육을 통하여 성 관련 지식과 태도는 6개월이 지난 시점에서도 상당한 수준으로 유지하였다. 앞으로 더욱 효과적인 성교육을 위해서 보건소와 학교는 서로 긴밀한 협조관계를 유지하여 성교육 사업에 필요한 재정적 바탕을 마련해야 할 것이고 그 다음으로는 그 내용에 충실을 기해야 하겠다. 그리고 학교에서는 쌍방향의 대화식 성교육을 통하여 충분한 지식의 습득과 실질적인 피임기술을 익힐 수 있는 시간의 화보에 노력하여야 할 것이다. 또한 한 두 번의 일과성의 성교육으로 끝나서는 안되도록 학교에서는 장기적인 계획을 세워 규칙적이고 지속적인 교육이 되도록 교과과정을 조정하고 보건소에서는 학생들이 싫증을 가지지 않도록 흥미 있고 다양한 교육내용을 개발하거나 중앙부처나 단체에서 개발한 프로그램을 도입하여 학교에 제공하여야 할 것이다.

We investigated the androgenic effects of $17{\alpha}$-methyltestosterone (MT) on gonadal sex reversal in juvenile red spotted grouper Epinephelus akaara. The fish were immersed in $17{\alpha}$-MT at 1 and 5 mg/L. Treatment method of $17{\alpha}$-MT was once weekly for 4 and 8 weeks. Fish were sampled at 12 months after end of the treatment period in order to histological analysis. At the initiation of an experiment (70 day after hatching), juvenile red spotted grouper have the paired primordial gonads with somatic cells bellow kidney in the posterior portion of the body cavity. Formation of ovarian cavity indicates that the ovarian differentiation beginning at 70 DAH in red spotted grouper. At 12 months after end of the treatment period, control group, $17{\alpha}$-MT 1 mg/L treatment group for 4 and 8 weeks, and $17{\alpha}$-MT 5 mg/L treatment group for 4 weeks were all female. However, sex-changed males without ovarian cavity were observed in the $17{\alpha}$-MT 5 mg/L treatment group for 8 weeks. In grouper, we firstly reported that the red spotted grouper be able to induce the primary males by hormone treatment prior to gonadal sex differentiation.

This study was done to determine the factors influencing smoking-cessation behavior in female university students. A total of 534 students participated in this cross sectional study by answering a questionnaire. The data collection was done between September 1 and October 31, 1997 The measurement tools used in this study were the self help change process scale (Cronbach's alpha＝.9930 : developed by Oh & Kim, 1996) for smoking-cessation behaviors, the self efficacy scale(Cronbach's alpha＝.8250 : developed by Sherer et al, 1982), the sex role acceptance scale (KR－20＝.7757 : developed by Kim, 1991) and the social support scale(Cronbach's alpha＝.9172 : developed by Park, 1985). The summarized results are follows : 1. The mean scores for smoking-cessation behaviors in smokers (N＝150) was 91.72 that was considered a middle score compared to the total possible score of measurement tool (150.0). The mean score for smoking-cessation behaviors by smoking-cessation step showed significant different between the groups(F＝11.71, p＝.000). 2. The group with no experience in smoking(N＝332) showed a high general self efficacy score (t＝5.24, p＝.000), and more openness to sex role acceptance(t＝-2.15, p＝.032) compared to the group with smoking experience (N＝202). 3. General self efficacy, sex role acceptance, and social support were not different significantly between the groups according to the steps in smoking-cessation. 4. Significant factors influencing smoking-cessation behavior (total, sub concepts) were religion, sex role acceptance, social support, smoking duration, smoking attitude, time of smoking onset, amount of smoking, drinking, and perception of health status. 5. Smoking-cessation behaviors which explained 11% of the variance were smoking attitude, and smoking duration. In conclusion, this study identified factors influencing smoking-cessation behavior. Thereby it will help in the development of smoking-cessation intervention strategies. For future research, exploration other determinants of smoking cessation behaviors, evaluation of intervention efficiency, and comparative study by gender characteristics are needed.

The objective of this study is to find the most effective educational method on Sex and AIDS/HIV among young people in Korea. The number of people with HIV amounts to 1,224 as of Sep. 2000, and is increasing continuously, especially among young people(National Institute of Health, 2000). In setting up the policy of health education on Sex and AIDS, the criteria should be the effectiveness. By two-stage cluster sampling, 4,713 students were selected from among the 19,093 students from 44 middle and high schools and divided into three groups and taken the education with three different methods( 〈lecture with slides show〉, 〈lecture without any material〉 and 〈lecture through broadcasting system〉) by the same lecturer with the same contents for about 50 minutes. To compare the effects of education by methods, the tests on the AIDS knowledge, AIDS attitude on AIDS and Sexuality attitudes with self-administered questionnaire were implemented three times, that is, ‘before’, ‘right after’ and ‘2 weeks later’ of the education. As to the degrees of change of AIDS knowledge, AIDS attitudes, Sexuality attitudes and subjective evaluation of the education, 〈lecture with slides show〉 was the most effective, 〈lecture without any material〉 was the second and 〈lecture through broadcasting system〉 was the least effective, respectively. In the cost-effectiveness analysis using the results of this study, 〈lecture with slides show〉 turned out to be the most effective, and 〈lecture through broadcasting system〉 was the second and 〈lecture without any material〉 was least effective. From these results, it is suggested that 〈lecture with slides show〉 is more effective health educational methods on Sex and AIDS than 〈lecture without any material〉 or 〈lecture through broadcasting system〉.

In situations of spatio-temporal perception about visuo-auditory stimulus, researches propose optimal integration hypothesis that perceptual process is optimized to the interaction of the senses for the precision of perception. So, when the visual information considered generally dominant over any other sense is ambiguous, the information of the other sense like auditory stimulus influences the perceptual process in interaction with visual information. Thus, we performed two different experiments to certain the conditions of the interacting senses and influence of the condition. We consider the interaction of the visuo-auditory stimulation in the free space, the color of visual stimulus and sex difference of testee with normal people. In first experiment, 12 participants were asked to judge the change in the frequency of audio-visual stimulation using a visual flicker and auditory flutter stimulation in the free space. When auditory temporal cues were presented, the change in the frequency of the visual stimulation was associated with a perceived change in the frequency of the auditory stimulation as the results of the previous studies using headphone. In second experiment, 30 male and 30 female were asked to judge the change in the frequency of audio-visual stimulation using a color of visual flicker and auditory flutter stimulation. In the color condition using red and green. Both male and female testees showed same perceptual tendency. male and female testees showed same perceptual tendency however, in case of female, the standard deviation is larger than that of male. This results implies that audio-visual asymmetry effects are influenced by the cues of visual and auditory information, such as the orientation between auditory and visual stimulus, the color of visual stimulus.

Arisaema robustum, which has the ability to change sex, was studied in a temperate broadleaf forest of Sanseong-ri, Joongbu-myeon, Gwangju-gun, Kyonggi Province, Korea. \ulcornerThe study, carried out from 1993 to 1997, focused on population dynamics energy budget among organs, size distribution, mortality, the relationships between sex and size, seed production and germination rate. In terms of energy budget among the organs, the ratio of aboveground to belowground biomass was 36.6 : 63.4 in non-female plants, and 81.4 : 18.6 in female plants. Also, in female plants, the ration of leaf to sexual organ biomass was 39.5 : 41.9. Therefore, the belowground ratio of female plants was lower than that of non-female plants. Plants were classified into 8 levels relative to the amount of leaf area by $100cm^2$. The rates of the smallest and the largest classes were 49% and 1%, respectively, and population distribution by size was relatively stable. The mortality averaged 13.1% per year and decreased in inverse proportion to leaf size (6.6% in the smallest and 0.0% in the largest size classes). Leaf areas were $64.1{\pm}48.5cm^2$ in non-flowering plants, $232.1{\pm}123.9cm^2$ in males and $444.8{\pm}153.9cm^2$ in females. The increase rates of leaf area per year varied from 1.9% in plants changing from female tomale, to 152.4% in plants changing from non-flowering to female. But plants which remained female for 2 years showed a decrease of 34.7%. >From this result, it is thought that the female plants invest more energy to reproduction than to vegetative organs. The correlation coefficient (CC) value between plant size and the number of seeds produced (0.55) was larger than the CC value between plant size and total seed weight (0.73). That is, the larger the plant size, the heavier the seed produced. The germination rate increased along with seed weight, and it was 95% in plants which were over 60mg fresh weight/seed.

This study focused on the disintegration and reconstruction of the family/kinship structure among the rural families of Korea. For this study, detailed data about the value related to the family/kinship, the family relationship, The attitude of divorce and remarriage, the social network, and the family/kin rites are gathered A total 593 subjects completed structured questionnaires. Major conclusion of the study are as follows : First, most of the rural respondents are found to support familism and boy preference slightly, and not to agree the reward of child value. So, their attitudes toward traditional values are changing slowly than urban residents. Second, the rural respondents shared the common perceptions that spousal and parent-child relationships has been changed toward the direction that the positions of wives and children are respected and the their influences are increased in the past 10 years. In addition, generational differences in the perceptions of relationship change and appropriate roles of wives and husbands are discovered. However, sex differences previously revealed in Seoul study were not found in the case of rural respondents. Third, generally, there are both remaining and changing aspects of conservative attitude toward divorce and remarriage, the level of change is different according to age and sex. And the difference by age is stronger than by sex. Fourth, the social networks of the respondents is characterized by two distinct trends, namely, strong parent-adult child ties and the close relationships between neighbors. fifthly, in the family/kin rites, traditional aspects coexist with changing aspects under the influence of industrialization and westernization. But the aspects of attitudes toward rites, it is showed the non-traditional tendency. Respondents who support westernization and socialization of family rites are young, highly eamed, and Christian.

Over recent 20 years, with socioeconomic development and change of recognition of the population, more people are concerned about their health and appearance. To obtain the change of frequency of malocclusion and the demand for orthodontic treatment, with this trend, 2460 freshmen and students of Yonsei Univ. in 1991, aged from 18 to 21 were examined excluding 187 students who have history of orthodontic treatment, 86 students who are undergoing treatment, 39 students who have too much missing teeth to classify. After analize the frequency of malocclusion and the demand for orthodontic treatment, following results was obtained. 1. Sex ratio in the prevalence of malocclusion was $91.7\%/90.8\%$, male to female, so there was no sex predilection. 2. With regard to Angle's Classification, each percentage of Class I, Class II div. 1, Class II div. 2 and Class III was $61.6\%,\;11.3\%,\;1.9\%\;and\;16.7\%$. 3. Of Class I malocclusion, percentage of crowding was 53.2, this occupied the largest part of single findings and prevalent findings in combinations were also crowding - crossbite and crowding - Protrusion. 4. Of Class I malocclusion, over the portion of$95\%$, Bialveolar Protrusion have arised alone. 5. The distribution of Demands for orthodontic treatment of malocclusion were $41.3\%$ in males, and $51.3\%$ in females.
