Objective: To develop a deep-learning-based bone age prediction model optimized for Korean children and adolescents and evaluate its feasibility by comparing it with a Greulich-Pyle-based deep-learning model. Materials and Methods: A convolutional neural network was trained to predict age according to the bone development shown on a hand radiograph (bone age) using 21036 hand radiographs of Korean children and adolescents without known bone development-affecting diseases/conditions obtained between 1998 and 2019 (median age [interquartile range {IQR}], 9 [7-12] years; male:female, 11794:9242) and their chronological ages as labels (Korean model). We constructed 2 separate external datasets consisting of Korean children and adolescents with healthy bone development (Institution 1: n = 343; median age [IQR], 10 [4-15] years; male: female, 183:160; Institution 2: n = 321; median age [IQR], 9 [5-14] years; male: female, 164:157) to test the model performance. The mean absolute error (MAE), root mean square error (RMSE), and proportions of bone age predictions within 6, 12, 18, and 24 months of the reference age (chronological age) were compared between the Korean model and a commercial model (VUNO Med-BoneAge version 1.1; VUNO) trained with Greulich-Pyle-based age as the label (GP-based model). Results: Compared with the GP-based model, the Korean model showed a lower RMSE (11.2 vs. 13.8 months; P = 0.004) and MAE (8.2 vs. 10.5 months; P = 0.002), a higher proportion of bone age predictions within 18 months of chronological age (88.3% vs. 82.2%; P = 0.031) for Institution 1, and a lower MAE (9.5 vs. 11.0 months; P = 0.022) and higher proportion of bone age predictions within 6 months (44.5% vs. 36.4%; P = 0.044) for Institution 2. Conclusion: The Korean model trained using the chronological ages of Korean children and adolescents without known bone development-affecting diseases/conditions as labels performed better in bone age assessment than the GP-based model in the Korean pediatric population. Further validation is required to confirm its accuracy.

Purpose: The purpose of this study was to analyze factors influencing health-related quality of life (HRQoL) among male adults. Methods: Participants were 196 male adults who were recruited from June to July 2016. Seven variables related to HRQoL including age, perceived stress, physical activities, problem drinking, social support, self-esteem, depression were measured. Data were analyzed using the SPSS/WIN 20.0 program and Amos 18.0 for descriptive statistics, Pearson correlation coefficients and path analysis. Results: The mean for HRQoL was 80.14. The path analysis showed that depression had the greatest direct effect on HRQoL. It was found that perceived stress had direct and total effects on HRQoL. It also mediated the paths of social support and self-esteem to HRQoL. These factors account for 68% of the total variance, and the fit indices of the model satisfied the criteria of fitness. Conclusion: The results indicate that these factors influencing HRQoL should be considered when developing programs to improve HRQoL for male adults.

In order to explore the power process, a hypothetical model which explains the interrelationships among 3 marital power(traditional, egalitarian, personal), 3 influence strategies(reward, coercion, emotional), and 2 negative conflict resolution styles(attack vs. avoidance) was developed. In order to examine the gender differences, male model and female model were developed separately and compared. Using the data collected from 182 males and 196 females, the hypothetical model was tested. For data analysis, SEM was used. As a result, 3 common paths were found: Greater use of emotional influence strategy increased attack as well as avoidance. Greater egalitarian power increased reward. Egalitalian power affected the use of coercion, but the direction was opposed: male's egalitarian power decreased coercion, while female's egalitarian power increased it. Except these, the analyses revealed the substantial differences between male and female. Based on the findings, the ways to reduce attack and avoidance, and theoretical implications were discussed.

By studying 3-D virtual human modeling, motion-capturing and clothing simulation for easier and safer work clothes development, this research aimed (1) to categorize heavy manufacturing work motions; (2) to generate a 3-D virtual male model and establish painting work motions within a 3-D virtual clothing simulation system through computerized body scanning and motion-capturing; and finally (3) to suggest simulated clothing images of painting work clothes developed based on virtual male avatar body measurements by implementing the work motions defined in the 3-D virtual clothing simulation system. For this, a male subject's body was 3-D scanned and also directly measured. The procedures to edit a 3-D virtual model required the total body shape to be 3-D scanned into a digital format, which was revised using 3-D Studio MAX and Maya rendering tools. In addition, heavy industry workers' work motions were observed and recorded by video camera at manufacturing sites and analyzed to categorize the painting work motions. This analysis resulted in 4 categories of motions: standing, bending, kneeling and walking. Besides, each work motion category was divided into more detailed motions according to sub-work posture factors: arm angle, arm direction, elbow bending angle, waist bending angle, waist bending direction and knee bending angle. Finally, the implementation of the painting work motions within the 3-D clothing simulation system presented the virtual painting work clothes images simulated in a dynamic mode.

In this study, causes and consequences of bullying were explored, focusing on victim personality and appearance factors. The research model included the relationships among bullying, important causes of bullying (aggression, cleanliness, and obesity of victims) and consequences of bullying (self-esteem and depression) and was tested through survey data from 594 (194 male and 404 female) middle school students. Data were analyzed using descriptive statistics, confirmatory factor analysis, and path analysis with SPSS and AMOS. In the results of the model tests, victims who are more aggressive, less clean, and more overweight are more likely to be bullied. In addition, adolescents bullied by others tend to have lower self-esteem and more depression. Furthermore, the model comparison was assessed by gender and a difference between the two gender models was found. In the check of critical ratio for difference, it was concluded that the cleanliness of the victim is a more important cause of bullying for male adolescents than for female adolescents. It is meaningful to confirm the effects of the victim's appearance factors on bullying in the literature focusing on personality issues of victims. Educators and counselors may refer to the findings in developing counseling guidelines and manuals to prevent bullying in school.

The major purpose of this study was to investigate the effect of intergenerational transmission of self-differentiation on psychological adjustment of college students. Specifically, the present study endeavored to test the causal model focusing on the effect of the father's and the mother's self-differentiation on college student's psychological adjustment through the student's self-differentiation. The data were collected from 254 male and 293 female college students and their parents by using self-administered questionnaire method. The casual model was tested through structural equation model by using AMOS 7.0 program. The results showed that mother's and father's self-differentiation had direct and indirect effect on student's psychological adjustment. The results showed that both mother's and father's self-differentiation had direct effect on son's self-differentiation level, which directly influenced his psychological adjustment. The test of structural equation model also revealed that daughter's self-differentiation level was positively influenced only by mother's self-differentiation, while father's self-differentiation did not influenced female student's self-differentiation. Both male and female student's psychological adjustment was directly influenced by his or her self-differentiation level.

The purposes of this study were to investigate 1) the effect of body exposure and color of a woman's suit on the perception of modesty, and 2) the effect of perceiver's sex and age on impression formed by the function of clothing variables. The instrument of this study consisted of a response scale and stimuli. Thirteen items of 7-point semantic differential scales were developed to measure the perceiver's impression on wearer's modesty. Stimuli were color pictures of a model wearing one of 8 types of suit constructed by a 2 $\times$ 2 $\times$ 2 factorial design. The manipulation of each level of the clothing variables were: color of the suit by black and red, leg exposure by varying skirt lengths to a Chanel-line and mini skirt, and neck exposure by shirt collar blouse and scarf. Two models, representing typical female college students living in Seoul, were selected to eliminate model effect. The sample include 384 subjects, consisting of 4 groups of male and female college students and middle aged men and women. Eight experimental groups were randomly assigned to one of eight stimuli based on between-subject design. One half of each group responded to model 1 and the other half to model 2 of same stimulus. Responses to the semantic differential scales were factor analyzed (pc model, Varimax rotation) to identify factors constructing impression of modesty. Two factors emerged regard­less of subgroups; Elegance and Extroversion factor. The first factor was found to be dominant, accounting for 60 percent of the total variance. The other accounted for just 11 percent. Multidimensional ANOVA (5-way, 3-way) was conducted to test the effect of the clothing variables against two factors identified from the factor analysis. Leg exposure was the most powerful variable affecting the impression of Elegance and Extroversion factor for all per. ceiver subgroups. Neck exposure had primary effect on the impression of Elegance, whereas it partially influenced that of Extroversion. Color of suit had only partial effect on the impression of Extroversion. Hypothesis I was partially supported from the findings above. The effect of perceiver's age and sex on impression by the function of clothing variables was tested by comparing the result between four subgroups. In forming an impression of the wearer's modesty, male college students were least affected by the manipulation of clothing variables, while middle aged males were affected most. In the female groups, there was no age difference and they fell between the male groups in the degree to which they were affected. Hypothesis II was supported only by age difference in two male groups, and by sex difference in two student groups.

This study aimed to analyze the relationship between ADHD trait and life satisfaction among male adolescents, and to examine the mediating effect of interpersonal initiation and internet game addiction on that relationship. The participants were 285 male students from middle and high schools. For this study, World Health Organization ADHD Self-Report Scale, Interpersonal Competence Questionnaire, Internet Gaming Use-Elicited Symptom Screen, and Satisfaction with Life Scale were used. PROCESS Macro 3.5 Model 4 was used to analyze a double mediating effect. Results revealed that male adolescents' ADHD trait was negatively correlated with interpersonal initiation and life satisfaction, while it was positively correlated with their internet game addiction. And, male adolescents' interpersonal initiation was positively correlated with life satisfaction, whereas internet game addiction was negatively correlated with life satisfaction. In addition, male adolescents' interpersonal initiation and game addiction were mediating ADHD trait and life satisfaction. These findings suggest that the interpersonal initiation and game addiction should be treated to improve life satisfaction of male adolescents with high ADHD trait.
