Purpose: The aim of this study was to determine the factors that influence safe sexual behaviors of Korean young adults and identify differences by gender. Methods: This study aimed to determine which factors affected safe sexual behaviors based on the Theory of Planned Behavior. Data from 437 Korean young adults (in their 20s and 30s) were collected via online survey between January 3 and January 28, 2022. The questionnaire included items on sexual body image, sexual role perception, sexual attitudes, sexual socialization, sexual communication, and safe sexual behaviors. Structural equation modeling was performed. Results: According to the overall model fit of the hypothetical model, the final model was acceptable and explained 49% of safe sexual behaviors. Sexual attitudes (β=h-.70, p<.001) and sexual communication (β=.53, p<.001) directly affected safe sexual behaviors, and sexual role perception (β=.42, p<.001) indirectly affected safe sexual behaviors in a combined model. There were gender differences in the path from sexual attitudes (β=-.94, p<.001) and sexual communication (β=.66, p<.001) to safe sexual behaviors and from sexual body image (β=.27, p<.001) to sexual communication. Conclusion: Sexual attitudes and sexual communication were predictors of safe sexual behaviors, which differed by gender. Strategies that consider sexual attitudes, sexual communication, sexual role perception, and differences between men and women should be developed to improve the safe sexual behaviors of young adults.

The concepts of phylogeny and floral genetics play a crucial role in understanding the origin and diversification of flowers in angiosperms. Angiosperms evolved a great diversity of ways to display their flowers for reproductive success with variations in floral color, size, shape, scent, arrangements, and flowering time. The various innovations in floral forms and the aggregation of flowers into different kinds of inflorescences have driven new ecological adaptations, speciation, and angiosperm diversification. Evolutionary developmental biology seeks to uncover the developmental and genetic basis underlying morphological diversification. Advances in the developmental genetics of floral display have provided a foundation for insights into the genetic basis of floral and inflorescence evolution. A number of regulatory genes controlling floral and inflorescence development have been identified in model plants such as Arabidopsis thaliana and Antirrhinum majus using forward genetics, and conserved functions of many of these genes across diverse non-model species have been revealed by reverse genetics. Transcription factors are vital elements in systems that play crucial roles in linked gene expression in the evolution and development of flowers. Therefore, we review the sex-linked genes, mostly transcription factors, associated with the complex and dynamic event of floral development and briefly discuss the sex-linked genes that have been characterized through next-generation sequencing.

Purpose: This study was to examine the fitness of a path model based on the objectification theory and to expand it by including the new variables to explain eating disorder symptomatology (EDS). Methods: The subjects consisted of 444 college women. Data was collected through self-report questionnaires that measured self-objectification (SO), social physique anxiety (SPA) and EDS as the original variables in the objectification theory, and influence of mass media (IMM) and sex-role attitude (SRA) as the new variables. Data was analyzed by SPSS/WIN 12.0 and Amos 5.0 programs. Results: IMM and SRA showed direct effect on SO. IMM had direct and indirect effect on SPA and EDS. SRA had direct and indirect effect on EDS, but only indirect effect on SPA. SO and SPA influenced EDS directly, and SO influenced indirectly EDS. Conclusion: Path analyses indicated support for the original theory and the expanded theory. It is necessary for repeated studies including various age groups of women to clarify the applicability of the objectification theory to Korean women's eating disorders. And it were recommended that we should promote womens' criticism of the image and message about the perfect female body presented in the mass media, and to highlight the relationship of gender equality to women's eating disorders in health education.

The purpose of this study was to be of use for the preparation of more desirable sex education system at elementary school, by making content analysis of the current textbooks related to sex education and surveying what opinions the persons concerned had about it. The purpose of this study were as follows; Elementary school textbooks were analyzed to find out what kind of sex education was included in them. And questionnaires on how to improve school sex education content were prepared, by which 207 male and female teachers were surveyed in the city of Paju and Koyang, Kyonggi province. The conclusions were as follows; 1. Content Analysis of Textbook Sex Education The content related to sex education was relatively much included in textbooks of the right life, morality and physical education. Although morality was a subject to be instructed for the third-grade students or older, elementary school students virtually received sex education from the first grade, as the right life and the joyful life were a subject for the lower-grade students, and this met the goal of sex education or the need of the times. However, sex education content leaned heavily toward family, family life or parental love. There was no mutual complement among subjects, and no link among grades, either. 2. Teacher Opinion on Sex Education Content for Each Grade When the subjects were asked about if sex education content was appropriate for each grade, they answered 20 items should be more emphasized and 6 items might be left out. And there were 6 items regarded by them as one that should be rearranged in consideration of grade. 3. The Ideal Opinion of Sex Education Content The following model could be recommended for elementary school sex education, which was designed to meet the objectives of school sex education as much as possible and to offer a systematic link among grades, based on the findings by textbook analysis and Questionnaire survey, and on elementary school sex education materials recommended by the Ministry of Education: The content selected for the first grade of elementary school was my body, cleanness of genitals, male-female cooperation, and family cooperation. For the second grade, the selected content was male-female physical difference, male female psychological difference, parental and I(origin of a birth). For the third grade, the selected things were important a body(cleanness of genitals), birth of a life, and male-female comprehension and cooperation. For the fourth grade, the selected things were physical development, management of genitals, physiology and management of menstruation, propagation and growth of organism, concern for the other sex, comprehension of and cooperation with the other sex, and prevention of sexual violence. Four the fifth grade, the selected things were secondary sex characteristic, physiology and management of menstruation, operation for phimosis, understanding of seminal emission, structure and function of the genital organs, birth and growth of a baby, television/sex information, and mass communications/sex information. For the sixth grade, the selected things were secondary sex characteristic, understanding of seminal emission, male-female cooperation, male and female role, male-female manners, mass communications/sex information, family and family life. Finally, what should be taught in sex education must be studied constantly, as it should be revised or supplemented periodically, according to student's sexual maturity or social, cultural changes.

The purpose of this study is to investigate the seven-hour sexuality education program for senior high school girl students and apply it to them to find out how this program affects their sex-related knowledge, sexual attitudes, and the self-efficacy of sexual behavior practice. The ultimate goal of this study is that high school girl students are to prevent unwanted pregnancy, STD and AIDS, after attending this sexuality education program. A non-equivalent control group pretest-post test design was used for this study. The number of experimental group consisted of 80 girl students and the control group was composed of 80 girls, too. A total of 160 freshmen from two commercial girls' high schools were selected by a convenience sampling method. This study was carried out in commercial high schools located in Daejeon, Korea from July 15th to October 31st, 2002. To discover the need for sexuality education, the researcher surveyed with a pre-designed questionnaire to 160 girls from the two different commercial high schools. The sex education curriculum was developed on the basis of the need of high school girl students for sex education survey results and literature review and a teaching-learning planning model and health belief model. The experimental group was taught the sexuality education program for seven hours from October 19th to 23rd, 2002 and each period continued for 50 minutes. The SPSS(10.0) Windows statistics software was used to analyze the data, along with frequency, percentage, $X^2$-test, t-test, and paired t-test. The instruments' internal consistencies were tested by Cronbach's alpha coefficient. The results of this study were as follows: 1. The increment of sex-related knowledge score after seven hour sexuality education was significantly higher in experimental group (t=-10.88, p=.000). 2. The increment of sex-related attitude score after seven hour sexuality education was significantly higher in experimental group (t=-2.67, p=.009). 3. The increment of the practice of self-efficacy of sexual behavior score after seven hour sexuality education was significantly higher in experimental group(t=-4.95, p=.000). In conclusion, sexuality education programs based on high girl students' educational desire, characteristics of development, a teaching learning planning model, a health belief model were effective to improve sex-related knowledge, sexual attitudes and the self-efficacy of sexual behavior practice of commercial high school girl students. This result can contribute to expand the school nurse's role in the sex education area and to develop theory-based school health nursing.

1. Partly because of Freud's greatemphaiss on the important of the child's successful weathering of the oedipal crisis and on the need to home both parents present if that period is to be successfully resolved, there has been a good deal of research on the effects of the absent father on the child's development. 2. Compared with boys whose fathers remained at home, boys were more immature and less secure in identification with their fathers. Some evidence suggests that father-absent children, particullarly boys suffer unusual difficulties in social relations wit their peers. 3. Emphasis on family quality , harmony, or climate as more important than father's absence, person is another recurrent finding among studies that attempt to analzed family factors in relation to juvenile deliquency. 4. The fatherless boys were more often judged to be anxious about sex and to be more effminated. 5. The sex-role problems of the boy without a father probably refect a number of factors, obviously they relate in part to the simple fact that he has not had a man around to provide a model of maliness. 6. Father is important to a girl's sex-role development not only because he is particularly interested in sex typing but also because he provides her with an opportunity to relate intimately to a man and to learn what it is like to invest emotionally in a male. 7. It is conceivable that children of broken marriages are more sensitive to martial problems and more ready than others to end an unhealthy relationship ; it is also conceivable that they are less likely to enter into a healthy one. 8. In some cultures it simply reflects the extreme amount of intimacy mother has with her son as compared with the amount of time compared with the amount of time father has available to spend with him.

This study shows trends and age-sex patterns of mortality in Korea, based on adjusted death registration data during 1956∼1980. Description on the data-the types of errors and their methods of adjustment-are presented elsewhere (Kim, 1986). Crude death rates have declined in 20 years to 7.0 in 1976∼1980, almost half the level of 13.0 in 1956∼1960. Mortality of females declined faster than males, especially at older ages. Substantial differences in provincial mortality are observed based on the expectation of life at birth. The difference between the highest and the lowest provinces is 9.2 years for males and 8.3 years for females during 1976∼1980. This study presents two interesting features of age-sex patterns of mortality in Korea. One feature is higher female mortality than males during childhood periods. However, infant mortality is higher for males than for females throughout the period, though the difference is much smaller than is expected from various model life tables. Another feature is the rapid rise in mortality for males after age 40. This pattern is found to be existed throughout the period 1956∼1980. Further studies are recommended to establish its causal linkage to traditional sex role (as main bread winner) and health behavior (smoking and drinking) of males and recent rapid industrialization in Korea.

The purpose of this study was to investigate factors related to the parental role in satisfaction and parenting behaviors. The subjects were 102 employed mothers and 110 unemployed mothers of 5-year-old children living in Seoul, Korea. The measures were questionnaire, the Parental Role Satisfaction Scale and the Parenting Behaviors Scale. The data were analyzed by Cronbach's ${\alpha}$, frequency, percentile, mean, correlation, multiple regression and Chow-test. Consistent with Belsky's model of the determinants of parenting, the parental role satisfaction and parenting behaviors of both employed and unemployed mothers were influenced by child characteristics, parent characteristics, and family factors. Results showed that the parental role satisfaction of both employed and unemployed mothers was correlated to child's birth order, temperament and health of child, mothers' and fathers' age, fathers' educational level, and family income. Parenting behaviors were also correlated to sex of child, child's birth order, temperament of child, parental educational level, and family income for employed mothers and to health of child, mothers' and fathers' age, mothers' educational level, and family income for unemployed mothers. Especially, father's age for employed mothers, and child's temperament for unemployed mothers, were the most strongly related variables for parental role satisfaction. On the other hand, family income for employed mothers, and fathers' age for unemployed mothers were the most strongly related variables for parenting behaviors.

Purpose: The mastoid region is ideal for studying sexual dimorphism due to its anatomical position at the base of the skull. This study aimed to determine sex in the Iranian population based on measurements of the mastoid process using different data mining algorithms. Materials and Methods: This retrospective study was conducted on 190 3-dimensional cone-beam computed tomographic (CBCT) images of 105 women and 85 men between the ages of 18 and 70 years. On each CBCT scan, the following 9 landmarks were measured: the distance between the porion and the mastoidale; the mastoid length, height, and width; the distance between the mastoidale and the mastoid incision; the intermastoid distance (IMD); the distance between the lowest point of the mastoid triangle and the most prominent convex surface of the mastoid (MF); the distance between the most prominent convex mastoid point (IMSLD); and the intersecting angle drawn from the most prominent right and left mastoid point (MMCA). Several predictive models were constructed and their accuracy was compared using cross-validation. Results: The results of the t-test revealed a statistically significant difference between the sexes in all variables except MF and MMCA. The random forest model, with an accuracy of 97.0%, had the best performance in predicting sex. The IMSLD and IMD made the largest contributions to predicting sex, while the MMCA variable had the least significant role. Conclusion: These results show the possibility of developing an accurate tool using data mining algorithms for sex determination in the forensic framework.
