Purpose: The aim of this study was to identify the contraceptive knowledge, self-efficacy according to the career tract of high school female students. Methods: This study used a cross-sectional, correlational design using an exploratory survey methodology through self-reported questionnaires. The questionnaires were administered to 369 high school female students using a convenience sampling. Results: In the experience of sexual behaviors(grasping hand, hugging, petting, deep petting, sexual intercourse), technical female high school students showed more experiences than female high school students. In the contraceptive knowledge, the score of high school students' contraceptive knowledge was higher than technical female high school students. In the contraceptive self-efficacy, there was not a significant difference between the technical female high school students and female high school students. In the female high school students, there were significant differences in the contraceptive knowledge according to grade, academic record, sex education experience and there were significant differences in the contraceptive self-efficacy according to grade, academic record, parents' attitude about acquaintance of the opposite sex. In the technical female high school students, there was not significant difference in the contraceptive knowledge according to demographic, sexual behavior, and contraceptive related characteristics but there were significant differences in the contraceptive self-efficacy according to grade, parents' attitude about acquaintance of the opposite sex, contraceptive education experience at school. There was positive relationship between contraceptive knowledge and contraceptive self-efficacy. Conclusion: Further research is needed to identify the prevalence rate of contraceptive attitude using more reliable variables. A sex education program should be developed for promoting use of contraceptive measure and formation of positive contraceptive attitude among high school female students.

PURPOSE: This study examined the necessity of a musculoskeletal injury-prevention program for automobile parts manufacturing workers by assessing the body composition, muscle strength, and posture according to sex and age. METHODS: Two hundred eighty-two workers (men, 218; women, 64; mean age, 38.97 years; and mean work tenure, 10.29 years) participated in this study. They completed a questionnaire on their general characteristics, excluding personal identification codes. The participants were evaluated for body composition, muscle strength, and posture using InBody, a hand dynamometer, and the Image J program through photography, respectively. An independent t-test and one-way analysis of the variance were used for the comparisons according to sex and age, respectively. RESULTS: Significant sex-related differences in muscle strength and grip force were observed (p<.05). In addition, the left-side pelvic inclination was significantly higher in the female participants than in the male participants (p<.05). Significant age-related differences in the skeletal muscle mass and muscle strength were observed around 40 years (p<.05). Significant correlations were observed among the body composition (skeletal muscle and body fat masses), muscle strength, and posture (pelvic inclination; p<.01). CONCLUSION: Significant differences in pelvic inclination by sex and muscle strength by age were found, even in healthy workers. Additional posture and muscle strength measurements will be needed for workers who participate in the musculoskeletal injury prevention program because they are exposed to an incorrect posture for many hours or in many repetitive tasks.

The purpose of this study is to compare sexual concerns and adjustment between men and women with spinal cord injuries. A total of 108 persons (67 men and 41 women), registered to the Spinal Cord Injury Organization or admitted at rehabilitation unit from February 1999 to February 2000, were selected as subjects of the study. Participants answered the questionnaires concerning importance of life events, sexual concern, sexual adjustment, relationship with a sex partner, and depression. The results are as follows : 1) There were no significant differences between men and women in the general characteristics except sexual dysfunction. 2) With respect to eleven different life areas, sex life ranked the fifth among men, whereas it occupied the lowest position for women among the 11 areas. However economic status was the most highly-ranked for both sex. 3) Men took much interest in the "methods and techniques for achieving sexual satisfaction", "Helping a partner cope emotionally with limitations on sexual activity", whereas women were interested in "Helping a partner cope emotionally with limitations on sexual activity" and "Ability to have children". 4) The means of sexual adjustment, relationship with a sex partner, and depression among men were higher than women. But there was no significant difference between two groups. As a result, the study suggests that there are no significant differences in the general characteristics between men and women with spinal cord injuries except sexual dysfunction. Men evaluated the sexual events highly compared to women, and differences were also shown in terms of sexual concerns between men and women. Therefore differential approaches to sexual rehabilitation are required; in both socio-psychological and physical aspects for men and particularly in socio-psychological respect for women.

The purpose of this study was to examine the differences in skin temperature and thermal comfort of participants in a $19^\circ{C}$ room (the recommended room temperature in the winter) depending on age, sex and clothing weight. Subjects were divided into four groups (6 young males, 5 young females, 6 old males, 6 old females) and experimental trials consisted of three conditions: wearing underwear in a $19^\circ{C}$ room (19CUW), without underwear in a $19^\circ{C}$ room (19C), and without underwear in a $24^\circ{C}$ room (24C). The results indicated the following: 1) There were no significant differences in mean skin temperature based on age or sex, and the mean skin temperatures of the four groups were in the range of 32.4∼$34.0^\circ{C}$. 2) In the 19C condition, the skin temperatures of the hands and feet of old females were higher than those of the other three groups. 3) In terms of perceived thermal comfort, young females showed a tendency to feel the most uncomfortable. Both old and young groups agreed that the 24C condition was the most comfortable. 4) Relational coefficients between thermal comfort and skin temperatures were higher in the young group than in the old group. Furthermore, the perceived thermal comfort had a stronger relationship with mean skin temperatures than with local skin temperatures. 5) The mean skin temperatures of subjects who indicated they were 'comfortable' were in the range of 31∼$36^\circ{C}$ regardless of age or sex.

The values of blood composition were analyzed by age, season, and sex from Chejuhorse in Korea. The results obtained were summarized as follow; 1. The values of white blood cell(WBC), packed cell volume(PCV), mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration(MCHC) were significantly different between age. The WBC value was decreased with the progress of age and the PCV value was lower in the early age of 1,2 to 3 years than in the higher age of 4 to 5, and over 6 years. 2. The mean value of MCV was increased with the progress of age but the adverse was true in MCHC. 3. In the case of seasons, the values of red blood cell(RBC), WBC, hemoglobin(Hb) PCV, MCV, mean corpuscular hemoglobin(MCH), MCHC, globulin(Glo), albumin/globulin(A/G) ratio, inorganic phosphorus(Pi), cholesterol(Chol), and chlorine(Cl) showed significant differences. The number of RBC was not varied from winter to summer but decreased in autumn. The number of WBC was high in summer and autumn, but low in winter and spring. 4. The values of MCV were high in autumn and winter, but low in spring and summer. 5. The values of MCH and MCHC were similar in spring and summer, but strikingly increased in autumn. 6. The values of Glo and A/G ratio were negatively correlated with the season; The value of A/G ratio was lowest in summer but no differences were observed in spring, autumn and winter. On the other hand, the value of Glo was highest in summer but no differences were observed in spring, autumn, and winter. 7. The values of Pi, Chol, and CI were high in summer and winter, but low in spring and autumn. 8. The values of RBC, MCV, and MCH were significantly different between sex. The value of the RBC count in male was higer than the female, but the adverse is true in MCV, and MCH.

The impact of gender, sex-role identity and cultural background on self - control behaviors was studied with the use of reports from 410 college students(201 Koreans and 209 Americans), who were administered both the Bem Sex Role Inventory and the Missouri Self Control Instrument. Gender, sex - role identity and cultural background significantly affected self - control and satisfaction. Regardless of cultural background, males showed a higher level of self - control and satisfaction than females. Androgenous students from both nations used a higher level of expressed/yielded self - control and more satisfied than the students with other sex - role identities. There were some differences in self - control between the Korean and American students. For the American students, the level of expressed self - control was the critical factor in explaining self - control behavior, whereas the level of yielded self - control was the critical factor for the Korean students. This was explained as a phenomenon of culture - bound relationships. Regardless of sex and sex - role identity, the level of satisfaction of Korean students was significantly lower than that of American students. The present results suggested that Korean students have some sort of conflict between self - control and satisfaction. The conflict can probably be attributed to the recent influx of western culture emphasizing goal - oriented control.

Little is known about the relationship between fathers and their preadolescent children in Korea or about variations in fathering by SES and sex role orientation. The purpose of this exploratory research was to examine variation in contemporary Korean fathering (e.g., warmth of fathering, frequency of father involvement, and task share of father involvement) and its influence on children's sex role development. One hundred and twenty-nine fathers, mothers, and their 11-13-year-old children completed standardized survey questionnaires addressing their childrearing practices, parental role involvement, spousal support, and sex role orientations. Data were analyzed using MANOVAs, t-test, correlational analyses, and multiple regression analyses. Mothers reported more warmth in parenting than did fathers. Regardless of sex of child middle class fathers reported more warmth than lower class fathers and lower frequency of task share than lower class fathers. Regardless of SES, fathers with working wives reported higher levels of task share of involvement relative to their spouse. Fathers who were more frequently involved with their children tended to receive greater support from their wives for paternal involvement. There were no differences in parenting by sex of child nor was fathering associated with children's sex role orientation. Girls' femininity was related to fathers' masculinity. SES, maternal support, fathers' femininity, parents' education level, and maternal work status had predictive ability for the ecological view that fathering is a dynamic process predicted by personal characteristics as well as contextual factors.

The aim of the present study was to determine the effect of paternal sex chromosome on early development of buffalo embryos fertilized and cultured in vitro. Embryos were produced in vitro from abattoir derived buffalo oocytes. The cleaved embryos were cocultured with buffalo oviductal epithelial cells and evaluated on day 7 under the phase contrast microscope to classify development. The embryos which reached the morula/blastocyst stage were fast developing, the embryos which were at 16-32 cell stage were medium developing and the embryos below 16 cell stage were slow developing. The embryos which showed some fragmentation in the blastomeres or degenerated blastomeres, were degenerating. Sex of emberyos (n=159) was determined using PCR for amplification of a male specific BRY. 1 (301 bp) and a buffalo specific satellite DNA (216 bp) fragments. The results thus obtained show that 1) X and Y chromosome bearing sperms fertilize oocytes to give almost equal numbers of cleaved XX and XY embryos, 2) male embryos develop faster than female embryos to reach advanced stage and 3) degeneration of buffalo embryos is not linked with the paternal sex chromosome. We suggest that faster development of males is due to differential processing of X and Y chromosome within the zygote for its activation and / or differential expression of genes on paternal sex chromosome sex chromosome during development of buffalo embryos fertilized and cultured in vitro which may be attributed to a combination of genetic and environmental factors.

The purpose of this study was to compare sex role typing in relation to self-concept in 6th graders by to their residential area. The subjects were 6th grade children: 126 boys and 127 girls. The sample included 85 (42 boys, 43 girls) from a farming area, 111 (62 boys, 49 girls) from Pohang City, and 57 (22 boys, 35 girls) from a fishing area. The instruments used in this study were Shimer's self-concept measure (Suh, 1980) and Bern Sex Role Inventory (Byun, 1979). Statistical analysis of obtained data was by $X^2$ test; 2 (sex) x 3 (residential area) x 4 (sex role category) ANOVA; and $Scheff\acute{e}$ test. The results were as follows: Girls from the fishing area were more masculine than girls from other areas. Androgynous children and urban children demonstrated a higher self-concept. There was no difference in level of self-concept between urban boys and girls, but boys in both farming and fishing areas demonstrated a higher level than girls. In all 3 areas, androgynous children evaluated themselves positively whereas undifferentiated children evaluated themselves negatively. There were significant differences in self-concept according to sex, living area, and sex role category. In the city, the feminine category was related to a negative self-concept while the masculine category was related to a negative self-concept in the fishing area. But in the farming area, feminine boys demonstrated a higher self-concept whereas feminine girls demonstrated a lower self-concept.

The purpose of this study is to investigate the relation between sex-role attitudes and marital family role structures. Research was conducted from May, 1989 in Seoul on 265 persons who are married. The statistical procedures used were frequncy, percentile, ony-way ANOVA, DMR, T-test, x2-test, and Pearson product correlation. The results are as follows: 1) The married men have more traditional sex-role attitudes than the married women. Their sex-role attitudes were influenced by the personal environmental variables such as age, husband's and wife's educational levels, family monthly income, family life cycle, marriage pattern, and child number. 2) The tendency of marital family role performances has no significant differences between the married men and women. Their marital family roles were influenced by the personal environmental variables such as husband's and wife's educational levels, wife's employment status, family monthly income, marriage pattern, and child numbe . 3) There is significant correlation between sex-role attitudes and marital family roles on the married men; When their sex-role attitudes are more modern pattern the structures of marital family roles are jointed. 4) There is no significant correlation between sex-role attitudes and marital family roles on the married women.
