It is well known that high school girls' mean achievement levels in science tests are lower than high school boys' and that fewer women than men are employed as scientists and engineers pursue scientific careers. Many research attributed the sex difference in achievement level in science and the lack of women in science among others, to the experiential differences in scientific activities and the differences in attitudes toward science and scientists. Therefore, the study had its object to examine the sex difference by high school students in scientific experience and attitudes toward science and scientists. The differences in science experiences were identified at eight schools over rural and urban areas in Kangwon province. Science activities surveyed included use of experimental materials and instruments, observation of scientific phenomena, and extracurricular scientific activities. Attitude scale contained the nature of science, scientific research methods and philosophical views held by scientists. The study found sex differences in scientific experiences and attitudes. i. e.: fewer high school girls than boys had experience with scientific activities, especially with extracurricular activities; however, girls had more positive attitude toward science and more active desire to participate in science. Consequently, the study implies that, in order to narrow the gaps between achievement levels for boys and girls, science education should take consideration of the sex difference in experiences with and attitudes toward science.

This Study investigated the relationships of care-oriented morality to gender and sex role identity in young adults. Care-oriented morality was assessed by the Ethic of Care Interview(ECI) while sex role identity was assessed by the Korean Sex Role Inventory(KSRI) with a sample of 48 men and 42 women between 20 and 35 years of age. The level of care-oriented morality of most of the subjects was Level 2. There was a significant difference between men and women in level of care-oriented morality by both x2 and ANOVA. That is, women averaged and levels 2.5 and 3 while men averaged levels 1 and 1.5. The ANOVA reveled difference in sex role identity types by levels of care-oriented morality on the ANOVA test.

It is well known that stress induces analgesia. This study was designed to demonstrate the stress-induced analgesia by employing hemorrhage and restraint and to investigate its mechanism and sex difference. The degree of pain was assessed by measuring the magnitude of jaw opening reflex produced by a noxious electrical stimulation in the dental pulp and by measuring the latency to withdraw the tail from a heat ray. Restraint showed an antinociceptive response. A significant increase in pain threshold on bleeding was shown and the increase was larger in male group than in female group. The tail flick latency (TFL) on bleeding after AVP antagonist injection into the ventricle was decreased and the decrease was greater in male rats than in female rats. Castration resulted in a significant reduction of TFL. This effect was reversed by treatment with sex hormones. TFL was decreased during hemorrhage in castrated rats. This response was opposite to that in non-castrated rats. TFL was further decreased during hemorrhage after infusion of AVP antagonist, and there was a significant sex difference. These results suggest that both restraint and hemorrhage produce an antinociception and that, in hemorrhage-induced analgesia, AVP and sex hormones may play an important role and male rats show a greater analgesic response.

The purpose of the survey was to identify the degree and the relationship of sexual knowledge, sexual attitude and need of sex education. This information will provide useful data for a more systematic. desirable, and practical sex education. The data was collected from 300 first grade schoolchildren (150 boys and 150 girls) of two Junior high school in K city. The data was gathered by questionnaire from Nov.21 to 28, 1995. The questionnaire was modified by authors using the questionnaire developed by Lief & Reed. Data was analyzed by using the statistical computer package, SAS to manipulate the data along with percentages, means, standard deviation, t-test, $X^2$-test, GLM, and Pearson correlation coeffiency. The results in this study were summarized as follows: 1. Sexual knowledge. - The mean score of sexual knowledges showed no significant differences between boys and girls(p<0.6180), but in the areas of biological differences(boys; $11.57{\pm}2.43$, girls; $10.93{\pm}2.41$, p<0.0242), and pregnancy physiology(boys; $9.28{\pm}1.87$, girls; $10.04{\pm}2.42$, p<0.0026) showed significant difference between boys and girls. 2. Sexual attitudes. - The mean score of sexual attitudes showed no significant difference between boys and girls (p<0.8286), but in the areas of masturbation (boys : $6.69{\pm}2.22$, girls : $5.65{\pm}1.88$, p<0.0001), and premarital intercourse (boys : $5,42{\pm}1.35$, girls : $6.00{\pm}1.33$, p<0.0002) showed significant difference between boys and girls 3. Need of sex education. - The majority of the subjects wanted to learn about sexual delinquency and it's prevention(57.7%), form a friendship with the other sex(56.3%), physical differences of the other sex(52.0%), psychological differences and the charateriatics of the other sex (50.3%) and meaning of love(50.3%). 4. The relationships between sexual knowledges and sexual attitudes. - Those who had higher sexual knowledges showed more positive attitudes towards sex, and showed statistical significance(r=0.2074, p<0.0003). 5. The relationships between general charateristics and sexual knowledge. - Better students(by self-perception of school performance) had higher knowledge scores about sex. 6. The relationships between general charateristics and sexual attitudes. - Those who wanted to learn more about sex, and better students had higher attitude scores about sex. - Those who were in high standard of living had higher attitude scores about sex as well. Suggestions based on above study are as follows' 1. The planned sex education showed be performed to the schoolchildren establish responsible attitudes about sex. 2. Systematic sex education through formal school education according to age is recommended. 3. Further studies should be done to measure the effect of sex education based on the needs of the schoolchildren.

The major purpose of this study was to compare the state anxiety of surgical patients by sex (male/female), area of operation (sex-organ/non sex-organ), and family planning (having the plan of child-bearing/having no plan of child-bearing). One hundred sixty patients who were to get surgical operation were equally divided into eight groups resulted from combination of variables of sex, area of operation, and family planning, The state anxiety of surgical patients was measured in terms of the discrepancy score between the state anxiety score on the State-Trait Anxiety Inventory (STAI) administered at a day before operation and the trait anxiety score on it which was administered at a day before discharge. In order to test statistically the differences among meant scores of the state anxiety obtained by eight groups, multiple comparisons were carried out by Scheffe method. The results of this study led to the conclusions that, (1) there was no significant sex difference in the state anxiety of surgical patients, when the area of operation and the family planning variables were disregarded, (2) the state anxiety of patients who were to get operation of their sex-organ was significantly higher than that of patients who were to get operation on the parts other than their sex-organ, when variables of the sex and the family planning were not taken into account, (3) there was no significant sex difference in the state anxiety of patients who were to Bet operation on the parts other than their sex-organ, when the family planning variable was disregarded, (4) the state anxiety of female patients who were to get operation on their sex-organ was significantly higher than the stale anxiety of male patients who were to get operation on their sex-organ, when the family planning variable was not taken into account.

Objective: This research has been conducted in order to conduct sex education using information and communication technologies (ICT) which is currently taught to elementary school students, understand how this method of education affects the knowledge of and attitude towards sexual health in them, so that it could be actually applied in classrooms. Subject: 115 students were divided into three different groups: a comparison group of 38 students (who were given no sex education at all), control 2 group of 39 students (who were given sex education via video programmes), and control 1 group of 38 students (who were given sex education using ICT). Research Tool: A questionnaire used by the literature studies. After verifying content validity, it was modified and supplemented in this way: sex knowledge was reduced to 26, and sex attitude was also reduced to 11. The reliability of the research tool was Cronbach's a=0.86 for sex knowledge tool, and Cronbach's a=0.81 for sex attitude tool. The collected data have been analysed using SPSS 11.0 program. The content validity was analysed by factor analysis and multiple regression analysis, and hypothesis verification was analysed using repeated measure ANOVA test. Result: 1) In sex knowledge marks, there was a significant difference according to the group (p=.009) and point of time (p=.000), and there was a significant interaction between the groups and point of time(P=.000). As a result, it turned out that both video programmes and ICT were significantly effective in improve the knowledge. 2) In sex attitude marks, there were no significant differences according to the group (p=.213), but there was a significant difference according to point of time (p=.002), and there was a significant interaction between the groups and point of time(P=.018). As a result, it turned out that only the education method using ICT was effective in improving the attitude. Conclusion: From the results of this research, it can be said that the sex education using ICT was the most effective method in improving the sex knowledge and attitude of students at elementary school. Therefore, it is advisable that the sex education methods using ICT should be developed and applied continuously.

This study reflects the demand of content elements related to "Human Reproduction" in elementary school science curriculum, and verifies its effects by developing and applying sex education contents available to elementary science class. The developed contents is composed of three sections in reference to the contents guideline for teachers. The contents include anatomical knowledge related to human reproduction and reflect social and cultural context of sex ethics. The first section: "How was I born?", second section: "Amazing changes in my body" and third section: "Healthy body, healthy mind." In the result of analysis of changes in sex knowledge and attitude after applying the contents, it showed statistically significant differences between experimental and comparative class. Thus, the developed contents made positive influence on improvement in elementary students' knowledge and attitude of human reproduction. However, it showed little difference in the effects of sex education contents by the grade and gender. In conclusion, if the sex education contents developed through this study is actively applied, it is expected to provide the elementary students with knowledge of the anatomic difference between male and female, its social and cultural understanding and responsibility for sex ethics. In addition, it is considered to be used as effective education programs and materials in elementary school science curriculum.
