This study investigated sex differences in children's self-efficacy and causal relationships between children's self-efficacy and home environment. The home environment factors included mother's efficacy, marital satisfaction, child rearing attitudes, and socio-economic status. The subjects were 491 fifth and sixth grade children and their mothers. The data were analyzed by t-test using the SAS $PC^+$ program and covariance structural analysis using the PC-LISREL VI. The results showed that there were no sex differences in children's global self-efficacy level, but there were sex differences in some subfactors. Furthermore, we found that the same causal model appears for both sexs in the relationship between home environment and children's self-efficacy. That is, socio-economic status of the home and mother's psychological factors influenced mother's attitudes for child rearing which had a direct impact on children's self-efficacy.

This study focused on factors influencing Internal and external problem (depression and antisocial) behavior among late-elementary children. Subjects were 481 boys and girls enrolled in the fourth. fifth. and sixth grades of public school. The contribution of grade. sex. stress, self-esteem. and social support from parents, teachers, and friends as well as school performance were studied. The instruments were the Adolescent Perceived Events Scale, the Self-Esteem Scale, the Social Support Scale for Children, the Revised Korean Version of the Center for Epidemiologic Studies' Depression Scale and Antisocial Behavior Scale. Results indicated that sex, stress, self-esteem, and the support of parents, teachers and friends reduced the level of depression. Grade, sex, stress, self-esteem, and teachers' support were related to the level of antisocial behavior. The results were discussed in terms of the effects of stress, personal and social resources, and school achievement on depression and antisocial behavior.

Objectives : This study was to prepare basic data about middle and high school students' school loss due to oral diseasea and to investigate the relevant factors. Methods : The survey is conducted for 575 middle school students in Busan and Gyeongnam. School loss was investigated based on the experiences of absences and leaving school early, which had happened from oral diseasea. The independent variables were oral health behaviors and sociopeconomic factors such as sex, age of their parents, educational level of their parents, family income. Factors related with school loss was analyzed by the multiple logistic regression method. Results : The experience ratio of leaving school early to the dental clinic or having difficulty in studying was higher in the case of high school student than in middle school student case. The parameters related with absence or leaving school early for oral disease were the education level, the distinction of sex, fear about medical examination and the standard of living. The reasons of absence or leaving early for visiting the dental clinic were related with education level, the distinction of sex, fear about medical examination, distrust of oral care and the satisfaction of oral health. The parameters having effect on school performance were education level, sex, fear about medical examination, distrust of oral care, cost burden, interests in oral health by the parents and school record. Conclusions : The oral health promotion should be developed to decrease school loss for students.

This study was conducted in order to figure out sexual experience among in Korean adolescents and its affecting factors. For the research method, it was a secondary analysis using raw data from the 13th(2017) Youth Risk Behavior Web-based Survey Data and the data from 62,276 adolescents were used for the analysis in this study. For the data analysis, frequency analysis, ${\chi}^2$-test, and logistic regression analysis were conducted by using SPSS 23.0 program, As a result of the research, the factors on sexual experience in male students included grade, school record, living type, economic state, depression, perceived stress, suicidal ideation, drinking, smoking, drug, and experience of sex education(p<.001) while those in female students included grade, living type, father's education, economic state, depression, suicidal ideation, drinking, smoking, drug, and experience of sex education(p<.001). Therefore, it is necessary to approach for helping from clinical settings, communities, and school healthcare through effective education and programs for preventing sexual problems, which reflect the factors associated with sex experience among adolescents in future.

Research on sex offense has shown that sex offenders are very heterogeneous. Sex offenders are heterogeneous in their probability of risk of recidivism. Some sex offenders are known to be much higher in their tendencies to reactivate than others. The study examined the predictive and explanatory power of static and dynamic risk factors in STATIC-99 and HAGSOR-Dynamic which have been used in Korean correctional facilities since 2014. STATIC-99 and HAGSOR-Dynamic showed moderate predictive accuracy for all crimes(AUC = .737, AUC = .597, respectively, ps < .001). However, when examining sex crime alone, only STATIC-99 predicted recidivism significantly(AUC = .743, p < .001). The incremental predictive power of HAGSOR-Dynamic was confirmed; the explanatory power of Model 2 comprising both static and dynamic risk factors were significant beyond Model 1 comprising only static factors(∆χ²= 12.721, p < .001), but this tendency was only applied to the model of all crimes. These findings were discussed with implications of practicing the sex offender assessment and treatment.

Sex of the Nile tilapia Oreochromis niloticus is mainly determined by an XX/XY system. However, accumulating evidences suggest the existence of additional sex modifying factors including environmental, autosomal and parental influences. In order to investigate the possibility of parental effects on sex ratios of tilapia progenies, in this study, a series of crosses was carried out using gynogenetic clonal fish, neomales, normal males and females, and YY fish. Crosses between clonal XX male and clonal female have yielded only female progenies and no parental influences were observed. However, in the crosses between clonal males and normal females, female parents were significantly associated with the progeny sex ratios ($X^2$=20.046, 7 d.f., p<0.01). Progeny sex ratios from the crosses between neomales and normal females ($X^2$=60.491, 5 d.f and $X^2$=28.072, 2 d.f.) also showed significant association with female parents (P<0.001). The stability of progeny sex ratios from repeated spawns were confirmed by using 6 different parental pairs. In 16 crosses between normal males and normal females, sex ratios of progenies showed clear maternal influences, and further analysis of the results revealed a negative correlation ($r^2$=0.7718, p<0.05) between the sex ratios of progenies from two different males, indicating a strong paternal influence. No statistically significant relationship between survival rates and sex ratios of progenies was observed in any genotypic groups. Taken together, the influence of parental pairs on progeny sex ratios in this species is evident although the cause of this influence is not clear.

This study investigated the self-concepts of Korean students based on Marsh and Shavelson's(1985) multidimensional hierarchical model. Reduced forms of the Self-Description Questionnaire(SDQ)-I and -II were administered to 308 5th and 6th grade students and 718 7th to 9th grade students. Results of 2 factor analyses indicated that sub-scales 9 and 11 were well established for SDQ-I and -II, respectively, partly confirming the multidimensionality of self-concept. The factors involving distinctions between academic and non-academic higher-order factors and between the academic/math and the academic/verbal factors were not so differentiated nor hierarchically arranged as proposed by the model. These differences may be attributed to the heavy influence of the academic self-concept on the other sub-factors. A Locality ${\times}$ Sex ${\times}$ Grade ANOVA showed main effects of locality favoring urban areas and of sex favoring boys.

The objective of this research is to survey of knowledge management in hospitals and to search the factors to impact the knowledge sharing and innovation behavior among employees. The data is collected with hospital employees by questionnaire method. Total number of analysis is 779 cases, and the collected data is analyzed by SEM(structural equation model). The work performance(WP) make influence the innovation behavior(IB) through knowledge sharing(KS) intention. The KS intention and IB are different in sex, age, education, work duration and work level. But, WP is different only in sex. The only personnel and organizational factors to affect KS intention, WP and IB are reciprocity(in personnel factor) and trust(in organization factor). Those factors mean the mental or psychological relationship among employees. So, to make more developed knowledge management in hospitals is to need more personal relationship than any other system management or incentives.

To monitor the reproductive patterns of endangered orangutan, Time-resolved fluorescence immuno assay (TR-FIA) were used to analyze metabolites of sex hormones in feces. Orangutan had long-term interbirth intervals (amenorrhea) during lactation period in which the secretion of sex hormones was repressed. The concentration of progesterone in the serum of pregnant orangutan was 30fold higher than that in non-pregnant orangutan. However, the concentration of hCG during pregnant period was different from the result of other primates. The present study suggested that age is not the important factor in determining the reproduction capability, because it is rather greatly influenced by the combination of various factors. Tracing metabolites of sex hormones in orangutan feces seems to be provide the effective solution for the infertility in orangutan. This study result shows the basic data in operating conservation project for endangered orangutan.

The difference of sex has been an object of interest and argument in medical, psychological, social, and cognitive science fields. This study started from the question of to what extent does the difference of sex have effect on successful interior design. In strive of resolving this, an experimentation of preference in terms of cafe interior design was performed with methods of human sensibility ergonomics. As the result, the difference of sex in preference regarding calf interior design could be observed. Males have main interest in the intensity of luminance, i.e. the brightness, whereas females attach importance to both qualify of light and color. In addition, there is a tendency for males to see cafe as a public place while females recognize cafe as a place for entertainment. Taking the result of this study into consideration can lead to successful gender specific cafe interior design.
