Purpose: The objective of this study was to develop a predictive model for the sexual experiences of adolescents using the random forest method and to identify the "variable importance." Methods: The study utilized data from the 2019 to 2021 Korea Youth Risk Behavior Web-based Survey, which included 86,595 man and 80,504 woman participants. The number of independent variables stood at 44. SPSS was used to conduct Rao-Scott χ² tests and complex sample t-tests. Modeling was performed using the random forest algorithm in Python. Performance evaluation of each model included assessments of precision, recall, F1-score, receiver operating characteristics curve, and area under the curve calculations derived from the confusion matrix. Results: The prevalence of sexual experiences initially decreased during the COVID-19 pandemic, but later increased. "Variable importance" for predicting sexual experiences, ranked in the top six, included week and weekday sedentary time and internet usage time, followed by ease of cigarette purchase, age at first alcohol consumption, smoking initiation, breakfast consumption, and difficulty purchasing alcohol. Conclusion: Education and support programs for promoting adolescent sexual health, based on the top-ranking important variables, should be integrated with health behavior intervention programs addressing internet usage, smoking, and alcohol consumption. We recommend active utilization of the random forest analysis method to develop high-performance predictive models for effective disease prevention, treatment, and nursing care.

This study tries to show the physical growth patterns and various adolescent characteristics by using longitudinal data for the height, weight, chest girth and sitting height of 1, 132 high school students in Seoul. And this study also tries to show what influencing factors on the physical growth of this aged population. The followings are the results. 1. The boys have their peak velocity of height when they are 12~13 years old. And the girls have when they are 10~11 years old. Peak velocity of weight for boys is at the age of 13~14. And for girls is at the age ofr11~12. Peak velocity of chest girth for boys is at the age of 12~13. And for girls is at the age of 11~12. Peak velocity of sitting height for boys is at the age of 13~14. And for girls is at the age of 11~13. So girls of this period grow more rapidly by around two years than boys. 2. The menarche of girls begins at the age of 12.4. So it begins 1.4 year before peak height velocity period. 3. Of life behavior boys contingency coefficient between essential time and height and weight is .5150 and .479 5, that between studying time and height and weight is .3344 and and .2912(In case of girls is .4735, .4321, .3247, .3134).

In order to improve health and nutrition management of Korean women, a new strategy to develop an information system on the internet to provide the Information on health and nutrition management for women during the life cycle was suggested. To achieve the goal, an adequate database protocol for korean women as well as health and nutrition management information system based on our culture and lifestyle should be developed. We suggest to categorize the information on health and nutrition management of Korean women according to the lifecycle as follows : 1) Health and nutrition management of adolescent women 2) Health and nutrition management of women in the marritable age 3) Health and nutrition management of pregnant women 4) Health and nutrition management of delivering women 5) Health and nutrition management of lactating women 6) Health and nutrition management of menopausing women 7) Prevention of women diseases 8) Stress management of women This system including women health and nutrition management information database provides health and nutrition management Information on the network so that anyone can use the information at any time. To constuct the system, it is necessary. 1. to identify information need for health and nutrition management of Korean women. 2. to provide the guideline of information system for women health and nutrition management. 3. to construct Information system for women health and nutrition management.

Premenstrual symptoms can begin at anytime after menache and usually remit with menopause. Numerous studies of the premenstrual symptoms have been reported, based on mature woman and clinic patients. As yet, however, no prospective study has specially examined the extent or nature of PMS in adolescents. The authors investigated the pattern of mood, behavior and physical symptom changes in the menstrual cycle for 230 high school students who reported premenstrual symptoms by using Baily Rating form(DRF), The scores on 21 symptoms of DRF were recorded daily for at least one menstrual cycle. The results as follows : 1) 1.7%(4/230) of the subjects who reported premenstrual symptoms met criteria for premenstrual dysphoric disorder(PMDD) by 30% change criteria. 2) The pattern of symptom changes in the menstrual cycle showed a clear increase in mean daily symptom score at premenstrual -1,-2 day. and reaching a maximum scores at the first day, rapidly decreased at day 4 during menstruation. 3) The mean daily symptom score in the menstrual phase was significantly higher than those in the premenstrual and postmenstrual phase, and significantly higher in the premenstrual phase than that in postmenstrual phase. 4) The scores of the subjects with longer duration of menstrual bleeding were higher than those of the subjects with the shorter duration. Particularly in the menstrual phase, there was a significant difference on the mean scores of physical symptom duster between the longer and shorter group. These results demonstrated that the mean daily pattern of symptom changes in the menstrual cycle for the subjects was similar pattern of change for the PMDD group, except high level of symptom scores if premenstrual phase. The adolescents might experienced more physical discomfort than the other symptoms in the menstrual phase Especially the subject with longer duration of mense flow were more likely to report more discomfort than that of shorter duration.

Objective : This study was conducted to confirm general differences in eating attitudes according to the sensory processing characteristics of women. Methods : The Adolescent/Adult Sensory Profile (AASP) and the Eating Attitude Test (EAT-26) were used to survey 241 women. Their eating attitudes according to the sensory processing characteristics was analyzed using an independent t-test and one-way ANOVA, and the post-analysis was performed using the Scheffe test. Results : Among the sensory processing characteristics, except for eating control due to low registration, binge-eating and foodlessness due to sensory avoidance, all eating attitudes were significantly different according to sensory processing characteristics (p<.05). The anorexic behaviour, binge-eating and foodlessness was shown to be negative in cases of those who had much lower registration than most people. All eating attitudes, such as anorexia, binge-eating and foodlessness, and eating control, were shown to be negative in cases of women whose sensation seeking was equal to or much greater than the general population. The binge-eating and foodlessness were shown to be negative in cases of high sensory sensitivity. The anorexic behaviour was shown to be negative in cases of elevated sensory avoidance. Conclusion : Eating attitudes differed depending on the sensory processing characteristics. As such, sensory integration mediation can be proposed as a method of controlling the eating attitudes of women in general.

Objectives : The objective of this study was to investigate the characteristics of language profiles according to whether or not Korean children with autism spectrum disorder(ASD) also have ADHD, and to examine the relationship with executive function. Methods : Participants in the study were boys with ADHD aged 6 to 11 years who visited the clinic from January 2012 to December 2013. In this study, 25 boys with ASD were included, and completed scales included the Korean version of Autism Diagnostic Interview-Revised(K-ADI-R), Korean version of Autism Diagnostic Observation Schedule(K-ADOS), Korean ADHD Rating Scale(K-ARS), and Korean-Conners' Parent Rating Scale(K-CPRS). They also completed neuropsychological tests and assessed language profiles. Patients were categorized into two groups(with ADHD and without ADHD). T-test and Multivariate analysis of covariance (MANCOVA) was used for analysis. Results : Statistically, no difference was found in receptive and expressive language ability between the ASD groups with and without ADHD. However, a lower score in Test of Problem solving(TOPS) was observed for ASD with ADHD than for ASD without ADHD, with problem solving and finding cues showing significant differences. Conclusions : These findings suggest that language profiles in the ASD group without ADHD could be similar to those in the ASD group with ADHD, but comorbid ADHD could lead to more difficulty in linguistic ability for problem solving and could be related with executive function of the frontal lobe.

The second part of this study is to typify plural sexuality articulated with fashion images in men's and women's popular fashion magazines in Korea since 2000 and ultimately to infer sexual ideology codified in modern fashion by a framework of this study, the socio-semiotic model. From this, sexuality represented in modern fashion was typified as follows: in women's fashion Traditional Femininity, Glamor Femininity, Androgynous Femininity, Babydoll Femininity and Genderless sexuality, while in men's fashion Traditional Masculinity, Macho Masculinity, Androgynous Masculinity, Adolescent Masculinity and Genderless sexuality. The conclusion of this study is as follows: First, modern fashion has been changed from a means expressing gender and class into a sign vehicle representing the new ruling system of age and sexual desire. The binary oppositional sexuality on center of man in the 19 C capitalist period has been gradually pluralized towards the post-capitalist period. Next, mainstream society in Korea is still positioned in the traditional heterosexuality, keeping the vertical power relationship between man and woman even in the post-modern period. However, the fact that both Traditional Femininity and Androgynous Femininity acquire the position of dominant femininity connotes the change of modern femininity. Finally, plural sexuality represented in modern fashion has family resemblance and it shows contextual flexibility within contemporary period as well as a historical context. As a result, sexuality floats with a specific historical and socio-cultural context, and fashion as a material culture represents a masquerade as a identity vehicle, which constructs and de-constructs sexuality at the same time.
