Purpose: This study aimed to examine the use of smart phones and their relationship with self-efficacy and academic achievement among students in 5th to 6th grade. Methods: 954 students in $5^{th}$ to $6^{th}$ grade were selected from three elementary schools in K City through purposive sampling. Data of 591 respondents were analyzed by $x^2$ test, ANOVA, correlation analysis and multiple regression analysis using the SPSS/WIN program. Results: First, 64% of the students possessed a smart phone and female students used their phone more than male students. 47.5% of the students said they first used a smartphone in their $5^{th}$ grade and 11.7% said in their 6th grade. Second, heavier use of smart phones was related to a lower level of self-efficacy (p<.001). Third, the more the students used a smart phone, the less they achieved in academic performance (Korean language: p<.001, mathematics: p<.01). Finally, the biggest factor influencing smart phone addiction was longer use of smart phones. In addition, lower self-efficacy and lower ability to adapt to difficult tasks were the factors influencing the increase in smart phone addiction. Less use of smart phones and higher self-efficacy resulted in higher achievement in academic performance. Conclusion: It is essential to decrease students' use of smart phones and improve their self-efficacy and academic performance. Intervention programs to reduce the use of smart phones should include a profound interest, a personality-oriented educational environment and sufficient dialogues with students at home, schools and the local society, beyond simple regulations to prevent adverse effects.

Purposes: This study examined the relationship between risk behaviors and sexual knowledge, sexual attitudes, and sexual experiences of male high school students. Method: A cross-sectional, descriptive study was conducted. Data were collected from 2 male high schools in metropolitan Gwangju. Five hundred forty-eight boys were enrolled in this study. Descriptive statistics, factor analysis, t-test or ANOVA, and Pearson's correlation were used for data analysis. Results: The mean sexual knowledge and sexual experience scores were relatively low, 0.60 out of 1 point, and 0.75 out of 4 points, respectively. Three attitude types of the students were identified: permissible, conservative and pleasure seeking attitude. The score of the permissible type was affected by the subjects' exposure to pornographic material. The score of the conservative type was affected by alcohol consumption and acquaintances with a heterosexual friend. The score of the pleasure seeking type was affected by their exposure to pornographic material, alcohol consumption, smoking, going to a video-room, and acquaintances with a heterosexual friend. There was a negative correlation between the permissible type and sexual knowledge, and a positive correlation between the conservative and pleasure seeking types and sexual experience. Conclusion: Male high school students who have been exposed to risk behaviors have a higher likelihood of indulging in sexual activity, and the pleasure seeking type appears to be related to sexual experience. An educational program may be needed to prevent risky behaviors and sexual experiences in male high school students considering their sexual attitude type.

The purpose of this study was to define the purchase behavior of online luxury fashion brand consumers that soon became new luxury consumption trends. To investigate online luxury fashion brand consumer's purchase behavior, three variables were suggested based on advanced researches. These variables include economic value, item variety and pleasure. Purchasing luxury online was not common but as cross-border online shopping market became popular, consumers began to purchase luxury items through online shopping platforms. Preliminary surveys was conducted on 20~40-year-old consumers who have experience in online shopping for luxurious items. Total 238 questionnaires were used for analysis. By using SPSS, frequency analysis, factor analysis, reliability analysis, correlation analysis, regression analysis, t-test and ANOVA were conducted. The results of the study were as follow; first, consumer's purchase behavior appeared to be influenced by the order of pleasure of shopping, economic value and item variety. Repurchase intention appeared to be affected by the order of economic value, item variety, and pleasure of shopping. Second, online luxury fashion consumers perceived that risk does not affect purchase intention and repurchase intention. Third, as purchase intention increases, repurchase intention also increases. Fourth, shopping value, age and channel risk also indicated meaningful differences. As an early study of luxury fashion brand products purchased directly online, the academic significance can facilitate an overall understanding of consumer behavior such as usage motive, risk perception, behavioral intention.

Purpose: This study aims to provide base data for designing education and counseling programs for child-raising by identifying the types, characteristics and predictors of parenting behaviors of married immigrant women. Methods: We used a self-report questionnaire to survey 126 immigrant mothers of young children, who agreed to participate, and who could speak Korean, Vietnamese, Chinese, Filipino, or English, at two children's hospitals and two multicultural support centers. Statistical analysis was conducted using descriptive analysis, K-means clustering, ${\chi}^2$ test, Fisher's exact test, one-way ANOVA, $Sch{\acute{e}}ffe^{\prime}s$ test, and multinominal logistic regression. Results: We identified three clusters of parenting behaviors: 'affectionate acceptance group' (38.9%), 'active engaging group' (26.2%), and 'passive parenting group' (34.9%). Passive parenting and affectionate acceptance groups were distinguished by the conversation time between couples (p=.028, OR=5.52), ideology of motherhood (p=.032, OR=4.33), and parenting stress between parent and child (p=.049, OR=0.22). Passive parenting was distinguished from active engaging group by support from spouses for participating in multicultural support centers or relevant programs (p=.011, OR=2.37), and ideology of motherhood (p=.001, OR=16.65). Ideology of motherhood was also the distinguishing factor between affectionate acceptance and active engaging groups (p=.041, OR=3.85). Conclusion: Since immigrant women's parenting type depends on their ideology of motherhood, parenting stress, and spousal relationships in terms of communication and support to help their child-raising and socio-cultural adaptation, it is necessary to provide them with systematic education and support, as well as interventions across personal, family, and community levels.

Purpose: The purpose of this study was to assess the relationship between psychological factors and symptoms of oral mucosal diseases by means of the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2). Methods: Three hundred and eighteen college students in Gyeonggi-do completed the MMPI-2 and a questionnaire related to symptoms of oral mucosal diseases and collected data were analyzed by Student's t-test and one way ANOVA. Results: Subjects who have experienced herpetic stomatitis revealed significantly higher mean values of T-scores than subjects who have not on hypochondriasis (Hs) and hysteria (Hy) clinical scales of the MMPI-2 (p<0.05). In comparison with subjects who have had recurrent aphthous ulceration, subjects who have not had it manifested significantly higher elevations on the schizophrenia (Sc) clinical scale (p<0.05). Subjects who have suffered oral lichen planus (OLP) showed significantly higher mean values of T-scores than subjects who have not on paranoia (Pa) (p<0.05) and hypomania (Ma) (p<0.01) clinical scales. Mean values of T-scores on Ma clinical scale were significantly higher in subjects having experienced glossodynia than in subjects having not experienced (p<0.05). Subjects having felt taste disturbance exhibited significantly higher elevations on Hs (p<0.0001) and Hy (p<0.01) clinical scales compared to subjects having not. Conclusions: Symptoms of oral mucosal diseases such as herpetic stomatitis, taste disturbance, OLP, and glossodynia were found to be related to Hs, Hy, Pa, Ma clinical scales of the MMPI-2. Therefore, comprehensive psychological evaluations of those oral mucosal diseases may be beneficial in a therapeutic approach.

This study aimed to analyze the consumption value and clothing pursuit benefits of genderless fashion based on gender identity. The study questionnaire was distributed to and collected from men and women in their 20s and 30s living in Seoul City and the Gyeonggi province. The collected data were analyzed by using Cronbachs α, factor analysis, K-means group classification analysis, and ANOVA. The study results were as follows. First, gender identity was categorized into three groups: the genderless group, the traditional gender rejection group, and the traditional gender acceptance group. Therefore, it is necessary to subdivide gender identity rather than acceptance and rejection of traditional gender roles. Second, an analysis of consumption value based on gender identity showed significant differences in terms of fashion value and expressive value. Therefore, it is important to establish a differentiated strategy based on the relevant gender identity group when establishing genderless fashion design or marketing strategy. Finally, the study results showed that clothing pursuit benefits based on gender identity, there was a significant difference in terms of individuality pursuit, deviation from the norm, and fashion pursuit. In particular, since the genderless phenomenon agrees with the characteristics of the MZ generation, it will be necessary to share brand information or product information through digital media or to utilize a sharing culture-that is, 'meaning out' tendency and 'flex culture' (i.e., conspicuous consumption).

The purpose of this study is to investigate the effect of the hip positions in frontal plane on abdominal muscle activities during bridging exercise. Twenty six subjects who have healthy conditions were asked to perform bridging exercise in three starting positions which are hip abduction, neutral and hip adduction. We used surface electromyography to compare the activities of both external oblique, internal oblique and rectus abdominis muscle. We analyzed the data by using repeated one way ANOVA, The alpha level was set at 0.05. The results showed that the muscle activities of both sides of external oblique, and internal oblique were significantly different among three starting positions. The activity of both sides of rectus abdominis were insignificantly different among three positions. The muscle activities of both sides of external oblique muscle and left internal oblique in bridging exercise with hip adduction position were significantly greater than hip neutral positions. The muscle activity of right internal oblique in bridging exercise with hip abduction positions. Our results suggest that bridging exercise with hip adduction position is recommended to lumbar stabilization exercise and the factor of hip position is important for controlling exercise intensity when designing bridging exercise program.
