Purpose : The purpose of this study was 1) to classify university student's attitudes toward sex, 2) to confirm the effects of sexuality course on sex-role stereotypes and sexual attitude in university student s. Method : The subjects in this study were 212 K university students in Kangwon Province between 3/7/2001 $\sim$ 6/13/2001. The instruments used for this study were the general characteristics, sexual attitude and sex-role stereotypes. The data was analyzed by frequency, percentage, mean, standard deviation, paired t-test, ANOVA, Pearson correlation coefficients, Factor analysis and Cronbach's $\alpha$ using the SPSS program. Result : 1. University students' attitude toward sex are divided into three types. Type I are called open mined : 16, 33, 28, 10, 18, 2, 30, 25, 26, 27, 22, 19, 29, 21, 9, 5 items. Type II are supporters of virginal purity : 8, 6, 31, 17, 14, 33 items. Type III express love through sexual intercourse : 20, 24, 7, 3, 15, 32 items. 2. There was a significant difference in the appearance and occupational characteristics of sex-role stereotypes before and after the sexuality course (t=2.562, p<.05). 3. In Type III, there was a significant difference in sexual attitude before and after the sexuality course (t=3.576, p<.0001). 4. The data showed the relationships between type III of sexual attitude and sex-role stereotypes (r=-.3 15, p<.0001). 5. Sex-role stereotypes according to the demographic characteristics before sexuality course were significantly different by age, gender, experience of military service, experience of sex edu cat ion an d experience of sexual intercourse. Sex-role stereotypes according to the demographic characteristics after sexuality course were significantly different by gender and experience of sexual intercourse. 6. Sexual attitude according to the demographic characteristics before sexuality course were significantly different by maj or (type I), age, grade, experience of military service and experience of sexual intercourse (type II), age, grade, gender, experience of military service, experience of sex education and experience of sexual intercourse. Sexual attitude according to the demographic characteristics after sexuality course were significantly different by religion and major(type I), age and grade(type II), age, grade, gender, religion and experience of sexual intercourse. Conclusion : This study showed that a sexuality course was effect ive in changing the sex-role stereotypes and sexual attitude of university students.

This study was designed to analyze the results of stress index by heart rate variability test. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 23,767 workers who had answered about questionnaires of a job position, age, smoking, drinking, exercise state and sex. The stress index(SI) and stress resistance(SR) were examined by SA3000P. We analyzed the differences of SI and SR according to job positions, ages, the state of smoking, drinking, exercise and sex by T-test or ANOVA with SPSS ver. 17.0. Regarding the differences of SI among job positions, the SI was highest in sales positions. Among ages, the SI was highest in 30s. In smoking, the SI was lower in non-smoking group. In drinking, there was no significant differences in SI. In exercise, the SI was lower in exercise group. In sex, there was no significant difference. The case of SR, SR was lowest in sales positions. Among ages, the SR was lowest in 40s. In smoking, the SR was lower in smoking group. In drinking, there was no significant differences in SR. In exercise, there was no significant difference. In sex, the SR was lowest in male. According to these results, we should establish the methods of controlling stress from the perspective of Korean traditional medicine.

The purpose of this study was to identify the need for sex education in middle school students Research subjects were 194 students who attended at I seminary in B city. The period of data collection was from July to August, 2001. Research instrument was composed of 61 structured items 17 items related to demographics and sex, 44 items related to the need of sex education. Data were collected through the self-report method by the researcher and one trained assistant. The instrument developed by the researchers was employed to measure the need of sex education and it's Cronbach's $\alpha$ = 0.9349 in this research. Data were analyzed by frequency, percentage factor analysis and t-test using SPSS WIN Program. The findings of this study are summarized as follows : 1. The highest score among characteristics of sex was 'less interest about sex(42.6%)', 39.0% of subjects got information about sex from friends or elders. 52.3% of subjects consulted friends or elders about sex problems. The number of sex education lessons was 1-2 times in school during last semester (61.0%). Education by the school nurse was 35.9% to students. 43.1% of subjects announced moderate satisfaction on sex education. 2. The mean score of the need for sex education was $2.88{\pm}0.47$ (lowest value 1, highest 4). The most wanted sex education factor was 'chastity and sexual responsibility($3.33{\pm}0.67$)' and followed by 'family and marriage ($3.26{\pm}0.62$)' and 'considerations of sex($3.07{\pm}0.69$)'. Meanwhile, the lowest wanted sex education factor is 'physiological characteristics of male ($2.47{\pm}0.72$)', followed by 'sexual behavior ($2.49{\pm}0.75$)'. The most wanted sex education item was 'the meaning of family ($3.54{\pm}0.75$)' and followed by 'the cautions to prevention from sexual abuse ($3.49{\pm}0.78$)' and sexual activity and responsibility($3.43{\pm}0.77$)'. Meanwhile, the lowest wanted sex education item is 'masturbation ($2.16{\pm}0.97$)', followed by 'circumcision($2.32{\pm}0.97$)'. 3. There is no significant difference between boys and girls in mean score about the need for sex education(t=-.715, p=.476). Sex education factor that girl-students wanted was 'physiological characteristics of female'. Sex education factor that boy-students wanted was 'family and marriage'. Sex education items that girl-students wanted were 'cautions during menstruation', the relation of ovulation and pregnancy', caution to prevention from sexual abuse' and sexual behavior and responsibility'. Sex education items that boy-students wanted were 'the meaning of family', 'the importance of marriage', 'male's sex organs', 'a wet dream', 'the method to resolve sexual curiosity', 'sexual intercourse' and 'the connection with the other sex'. In conclusion, the mean score of the need for sex education is medium. The route to attain knowledge about sex and sexual problem is through consulting friends and elders. Therefore, it is necessary to give sex education that is suitable to the subject's needs and methods. Also, it is necessary to give differently strong point about sex education between female and male students.

Purpose: The purpose of this study were to analyze fatigue patterns of the rectus femoris muscle by isometric contraction. Methods: Twenty healthy subjects(10 male, 10 female) participated in this study. Maximal voluntary isometric contraction(MVIC) was measured by the dynamometer. Muscle activity was recorded from the rectus femoris muscle. During the experiment, the subject was seated in the chair. The measured items, median frequency(MDF) and root mean square (RMS), were collected from the surface EMG. All data were analyzed using repeated measures ANOVA. Results: There was significant difference of MVIC between male and female. Endurance time was significant difference by the level of MVIC but no significant in the main effect(sex) and interaction effect. The MDF and fatigue index were significant differences in the interaction effect. The RMS was not significant difference in both of main and interaction effect. The muscle fatigue patterns of female was greater than male after 60% MVIC. Conclusion: This study showed that sex differences of muscle fatigue were started from 60% MVIC.

This research was to identify the relationships between sex role attitude and the preference of fashion advertising formatted by sex role expression, and to examine the relationships among sex role attitude and sociographic variables. This research has been done for 618 university students and working group who are living in Cheongju and Seoul. For data analysis, descriptive analysis, ANOVA, and t-test were used. The results are the following: 1. In the view of the preference of fashion advertising, the stereotypical fashion advertising has more point than the androgynous fashion advertising. 2. The advertising formation preference showed a little difference significantly by sex role attitude. The group with conservative sex role preferred the stereotypical fashion advertising. The group with open-minded sex role preferred the androgynous fashion advertising. 3. Women preferred the androgynous advertising. As the aged, they preferred the stereotypical fashion advertising and have the conservative sex role. University students have more intention to buy with an androgynous fashion commercial than working group have and they have the open-minded about sex. The group subscribed the fashion magazine has more preference for androgynous fashion advertising, as they have more open-minded sex role than other group not subscribed the fashion magazine. This results imply that the androgynous formatted advertizing is still hard to get the influence of a general market promotion because most consumers have a low androgynous fashion advertizing preference. The preference of the fashion advertizing which expressed a sex role showed significant differences as social demographics, and a sex-role attitude. Therefore, the market segment and advertising strategies which are based on sex role and consumer characteristics would be very effective.

Sex does not mean simply the physical behaviors related to man and woman, rather the sexuality needed socializing process toward total personality. It is believed that religion or social norms on sex, limit talking about sex openly. But children have, their own sexual thinking and want to know why and how. This survey was conducted to find out the need in sex education of primary school students and their parents in Seoul area, comparing students'sexual knowledge, attitude, and behavior to their parents', in October 1989. Total 400 students and their parents who are attending two primary school in Seoul, were given the questionnaires, and 395 students' and 310 parents', respectively, were finally analyzed. The following results were obtained. 1. The mean of 11 questions In asking sexual knowledge of students was 6.18, and showed no difference between boys and girls. But the higher grade, the higher score. 2. The positive attitudes on marriage and sex roles were showed, but negative on physical changes with puberty, which was same to the parents' reaction. 3. Moro than three-forths of students wanted to take sex education class, and one-third of them believed that it should be conducted by school nurses. This was accorded with their parents. 4. The sexual knowledge degree and attitudes of parents went proportionately to their higher educational background. Protestants reacted more negatively to the given sexual terms. No significant difference was made among the age groups of them. As stated above. the degree of sexual knowledge and attitudes are movable accordingly to their children's sexual thinking and need. Therefore, it is strongly recommended that sex education In the primary schools should be conducted systematically involving parents, especially mothers. And it is suggested that school nurses undertake their responsibilities as the sex educators.

Objectives: To date, studies have not comprehensively demonstrated the relationship between stroke incidence and socioeconomic status. This study investigated stroke incidence by household income level in conjunction with age, sex, and stroke subtype in Korea. Methods: Contributions by the head of household were used as the basis for income levels. Household income levels for 21 766 036 people were classified into 6 groups. The stroke incidences were calculated by household income level, both overall within income categories and further by age group, sex, and stroke subtype. To present the inequalities among the six ranked groups in a single value, the slope index of inequality and relative index of inequality were calculated. Results: In 2005, 57 690 people were first-time stroke patients. The incidences of total stroke for males and females increased as the income level decreased. The incidences of stroke increased as the income level decreased in those 74 years old and under, whereas there was no difference by income levels in those 75 and over. Intracerebral hemorrhage for the males represented the highest inequality among stroke subtypes. Incidences of subarachnoid hemorrhage did not differ by income levels. Conclusions: The incidence of stroke increases as the income level decreases, but it differs according to sex, age, and stroke subtype. The difference in the relative incidence is large for male intracerebral hemorrhage, whereas the difference in the absolute incidence is large for male ischemic stroke.

The objective of this study was to search out the motive and it's degree of the advertising involvement and to verify how the consumer's reaction have influenced on the effect of the advertising. In this study the questionaries used and objects were 236 working women form 20 to 39 years old. The dates were analyzed by reliability mean standard deviation percentage Duncan test t-test factor analysis correlation ANOVA and regression. The outcome of the analysis can be as follows : 1. Consumer's advertising involvement in the clothing goods was standing on 'Emotional' 'Expressional' or 'Economical' position. Among the factors affecting the consumer'sbehaviors. 'Usefulness' 'Like or Dislike' or 'Uniqueness' are the major 3 bases for perceptive evaluation 'Activity' 'Uncomfortableness' and 'Tranquility' are the 3 factors extracted from consumer's emotional reaction. 2 There was little difference in the size of advertising effect among the cluster types classified by each difference motive of the clothing advertising involvement. 3. Perceptive evaluation of the types of advertising appeal the non-sex-appeal advertising was inclined to "Usefulenss' or 'likes' while the sex-appeal advertising depending rather highy on 'Uniqueness' In respect of emotional reaction "Tranquility' was on non-sex-appeal advertising while more 'Activity' or 'Uncomfortable' feeling were on sex-appeal advertising. 4. In the light of 'advertising style' 'brand image' or 'purchase stimulation' the non-sex-appeal advertising was rather favorable received by the consumer's than the sex-appealing one. 5. All those surrounding factors excluding the 'uniqueness' are closely co-related to purchase stimulation.

The present investigation was carried out to study the possible cause for reciprocal difference in silkworm hybrids. By utilising the polyvoltine race Pure Mysore (PM) and newly evolved breeds (CSR2, CSR5, CSR16 and CSR17), the direct and reciprocal crosses of polyvoltine ${\times}$ bivoltine and also bivoltine hybrids were studied. The hybrids of polyvoltine ${\times}$ bivoltine (direct) are superior to their reciprocal crosses in respect of cocoon yield, cocoon weight and filament length. The reciprocal crosses of polyvoltine ${\times}$ bivoltine are superior to their direct crosses in respect of fecundity and short larval duration. No significant differences were observed in the characters like cocoon shell ratio, raw silk percentage, denier, reelability and neatness in both polyvoltine ${\times}$ bivoltine direct crosses and their reciprocals. The expression of cocoon characters as a function of sex revealed that direct crosses (polyvoltine ${\times}$ bivoltine) showed higher cocoon weight, pupal weight, shell weight and longer filament length in females than the reciprocal crosses (bivoltine ${\times}$ polyvoltine), where as these characters in males were almost the same in both direct and reciprocal crosses, indicating that the sex-linked genetic factor played a more important role. it was clear that difference in cocoon yield observed in reciprocal crosses of polyvoltine ${\times}$ bivoltine was due to the low cocoon and shell weight in females which was turn due to presence of early maturity genes (Lme) linked with sex-chromosome (X) which effect on larvae period of the silkworm. In bivoltine hybrids, i.e., both direct and their reciprocals crosses, all the characters viz., hatching percentage, larval duration, survival, cocoon weight, cocoon shell weight, cocoon shell ratio, raw silk percentage, filament length, denier, reelability and neatness did not show any significant difference (except number of eggs laid by moth) which could account for presence of same maturity genes (Lm) in both direct and reciprocal crosses. it was clear that reciprocal differences occur when the hybrids are prepared from the parental strains with different voltinism.
