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.

The locus coeruleus(LG) is known to be observed a sexual dimorphism in rat CNS. LC is the largest collections of norepinephrine(NE)-containing neurons in the mammalian brain. Especially in rat, all LC neurons contained NE unlike other mammalians, so that specific reactions were found in the tyrosine-hydroxylase(TH) immunoreactive neurons. Sexual dimorphism of rat LC has affected by genes before sex hormone appeared, thereafter affected by sex hormones. In these day, many scientists founded morphological differences between male and female LC morphology, but differences of entire structure was not founded. Thus we investigated sex differences of the LC neuron's morphology in rat by three-dimensional(3-D) reconstruction using Confocal laser scanning microscopy(CLSM). We reported that neuron's shape was relatively-large multipolar neurons and neuron's processes in dorsal LC proceeded to ventral direction in the male and female rat. Male had a longer anterior-posterior length than female had in dorsal LC. In addition to middle-LC, male rat's LC had a more thicker posterior region but had not viewed in a previous study. In reverse, female rat's LC had a thicker anterior region like a previous study. This results using 3-D reconstruction by CLSM showed that the male's LC was more wide-ranging than female's relatively.

In order to research the interrelationship of symptoms of 5 visceral diseases through Pearson's correlative coefficient and to understand the diagnostic importances of each symptom and sexual differences in the main symptoms of each visceral diseases using Cronbach alpha. For this 500 female and 120 male cases of questionnaire were collected and analyzed. In the main symptoms of 5 visceral diseases, there were a little differences between this results and existing symptom-complex system. And in the comparison of most frequently manifesting symptoms to male and female subject, Heart and Pancreas and Kidney disease were almost same, but Liver disease was different and Lung disease was slightly different. Conclusively, the diagnostic reliability of the abstracted symptom-complex of 5 viscera was graded from Kidney(Cronbach alpha 0.8771555), Pancreas(0.865978), Liver(0.815013), Heart(0.78653) to Lung disease(0.6294695) sequentially. And the each Cronbach alpha was valuable to be permitted as diagnostic criteria of 5 visceral diseases.
There have been many studies from the genetic system to physical activity and emotional expression such that there are gender differences. The purpose of this study was to determine how the structural characteristics of cortical thickness differ between males and females. This study used data from the Human Connectome Project (HCP). To analyze age-specific sexual dimorphisms of cortical thickness, selected 8-80 year old subjects were divided into five detailed age range groups according to each criterion. A total of 1,700 individual brain MRI T1 data were registered in stereotaxic space for analysis and classified into white matter (WM), gray matter (GM), and cerebro-spinal fluid (CSF). For surface-based analysis, the WM/GM surface was reconstructed from a spherical polygon model with 40962 vertices per hemisphere, and each vertex was extended to the GM/CSF boundary. Cortical thickness was then measured between each vertex using the t-link method. In the statistical analysis, intracranial volume was used as a covariate to exclude the effect of the difference in brain size of each individual, and the result of using age as a covariate was added to confirm the age effect within each group. Gender differences in cortical thickness had significant results by group. This may be an index to explain diseases with sexual dimorphism in prevalence or become a basis for explaining the characteristics of each sex that appear in behavior, personality, and aging. Therefore, the results of our study could be a criterion for age classification in future studies and for understanding 'normal' sexual dimorphism.

Sexual dimorphism of the mouthpart, antenna and mandible of the Cyllorhynchites ursulus in South Korea was studied with linear measurements. The mouthpart and antenna measurements were conducted with a stereoscopic microscope using 122 specimens (72 males and 50 females). Microscopic observation of the mandible were conducted with a Field Emission Scanning Electron Microscope (FE-SEM) using 103 specimens (73 males and 30 females). Results showed that the size difference between males and females was significant in the size of the mouthpart and antenna. On the other hand, we could not detect sexual size dimorphism in the microstructure of the mandible. The bivariate plots made by the result of Principal Component Analysis (PCA) and Discriminant Analysis (DA) showed a size dimorphism in the size of the mouthpart and the antenna between males and females. Based on our study, sexual dimorphism in the mouthpart and antenna exists in C. ursulus from the South Korean population, and this difference seems to be related to the behavioral differences between males and females.
Objectives: The study was designed to assess the trends of the incidence of HIV among young people and their sexual risk-taking behaviors by gender in Korean college students. Methods: The cross-sectional study was used from college students from selected 60 among 208 4-year colleges and universities in 9 provinces and Seoul. A self-reported anonymous questionnaire administered and completed to a national representative sample of 4-year college students from May 15th to June 14th in 2003. We analyzed 2,385 cases. The overall response rate was 82.0%. Results: After controlling age effects, male students were more likely to be sexually experienced than female students(40.0% vs. 8.1%), OR=5.5, p<.000. The proportions of 19 years and before reported for initiation of sexual intercourse were 18.6% for males and 3.2% for females. Males reported significantly younger ages than females at initiation of sexual intercourse(p<.01). Only 14.8% of current sexually active subjects reported consistent use of contraceptive methods. After controlling age effects, male students reported a higher proportion of sexually experienced respondents with one or more casual partners(excluding a formal partner) during the last 12 months than women(38.8% vs. 22.2%), OR=2.2, p<. 05. Conclusion : This study can conclude that although males students initiate sex earlier and have higher percentage of sexual experience, the percentage of sexually experience female students has risen rapidly compared to the past. This data revealed a number of young people were at risk for HIV infection. Both genders are equally likely to have engaged in inconsistent condom use even though when they have a sex with an unknown partner. These findings suggest that practical sex education focused on using condom use should have been included in the school curricular. Educational and community interventions need to prevent sex-related problems.

Objectives: Adolescents who engage in unhealthy behaviors are particularly vulnerable to anxiety. We hypothesized that participation in physical activity could influence the relationship between anxiety and unhealthy behaviors in adolescents. These behaviors include smoking, alcohol consumption, and unsafe sexual activity. Methods: This study included 50 301 students from the first year of middle school to the third year of high school, all from Korea. The unhealthy adolescent behaviors examined included current alcohol consumption, current smoking, and unsafe sexual behavior. Anxiety levels were assessed using the Generalized Anxiety Disorder-7 questionnaire (GAD-7). Results: The participants had a mean age of 15.19 years and an average GAD-7 score of 4.23. No significant differences were observed in GAD-7 score among exercising participants when categorized by smoking status (p=0.835) or unsafe sexual behavior (p=0.489). In contrast, participants in the non-exercise group who engaged in these behaviors demonstrated significantly higher GAD-7 scores (p<0.001 and 0.016, respectively). The only significant interaction was found between unsafe sexual behavior and exercise (p=0.009). Based on logistic regression analysis, within the non-exercise group, significant positive associations were observed between current smoking and anxiety (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.18 to 1.57), as well as between unsafe sexual behavior and anxiety (OR, 1.33; 95% CI, 1.02 to 1.73). However, within the exercise group, no significant association was found between anxiety and either smoking or unsafe sexual behavior. Furthermore, no significant interaction was observed between unhealthy behaviors and exercise. Conclusions: These findings are insufficient to conclude that physical activity influences the relationship between unhealthy behaviors and anxiety.
This study focused on the relationship between ego- resilience and stress coping styles of male and female adolescents. The study also tried to identify differences in stress coping styles based on sexual differences and the level of ego- resilience in adolescents. Ego-resilience showed a positive correlation to problem-focused and social support seeking coping styles and a negative correlation to emotion-focused coping style for both male and female adolescents. Canonical Correlation analysis revealed that self-confidence among four sub-domains of ego-resilience made the most outstanding contributions in predicting stress coping styles of female adolescents. The self-confident female adolescents tended to use the problem-focused coping style. For male adolescents, the optimistic attitude among four sub-domains of ego-resilience was the most significant factor in predicting emotion-focused coping style. Female adolescents tended to use more varied coping strategies than male adolescents in stressful situations. The group of adolescents who had a higher level of ego-resilience reported more problem-focused and social support- seeking coping styles in stressful situations. Conversely the group of adolescents with lower level of ego-resilience tended to use emotion-focused coping strategy. The results of this study have important implications for theory, research, and practice. Development of ego-resilience in adolescents based on sexual differences was an important task for their effective coping strategies.

The purpose of this study was to analyze the differences in dating violence perception of dating violence perception of university students. As a research tool, CTS2 was used as a measure of dating violence, a measure developed by Kim(1999) was used, and a measure of dating violence by Jeong(2013) was used. Data analysis was performed using independent sample t-test and multi-variate analyses. The results are summarized as follows. First, female students showed higher differences in total violence against violence and psychological violence than boys, while boys showed higher physical violence than girls. Health majors were significantly higher in total dating violence and psychological violence than students in humanities and social sciences. There was no significant difference in dating violence offenses with or without sexual experience. Only psychological violence showed an interaction effect between gender and sex experience. Second, female students were significantly higher than male students with significant differences in recognition and sub-factors. Health majors were significantly higher in both date violence perception and lower factors than humanities and social sciences. Students without sexual experience perceived overall dating violence more than students with sexual, physical and cyber violence being significantly higher.

This study was undertaken to identify the perception and sexual attitude of nursing students and obstetrics and pediatric nurses towards unwed mothers, and to identify differences in the general characteristics. Data were collected as a self-reported questionnaire survey from September, 2018 to January, 2019. Subjects included 94 nursing students enrolled at 2 nursing colleges, and 101 nurses of 8 hospitals located in the B & C Metropolitan. The data collected was analyzed by descriptive statistics, frequencies, percentages, means and standard deviations, independent t-test, and one-way ANOVA. Comparing results obtained from nursing students and nurses revealed a statistically significant difference in their overall perception of an unwed mother and sexual attitude. The perception of an unwed mother showed significant differences considering the grade, age and sibling status of nursing students, whereas nurses revealed significantly different perceptions according to their age, occupational position, clinical career, career of current work department, marital status, and children status. Sexual attitude was significantly different for nursing students according to their experience contact with unwed mother, whereas perception of nurses differed significantly for sexual attitude according to experience contact with unwed mother, types of hospital, and marital status. We propose that data obtained from this research can be used as basic data for research and education related to the perception of unwed mothers and sexual attitude of nursing students and nurses.
