Purpose: This study aimed to examine the effect of parental self-esteem on late school-aged children's media device addiction by mediating marital conflict and children's self-esteem. Methods: This study used data from the 11th (2018) Panel Study on Korean Children. The participants consisted of 1,082 family triads (fathers, mothers, and children). Data were collected using the Rosenberg Self-Esteem Scale, Marital Conflict Scale, and K-Internet Addiction Scale. The data were analyzed using structural equation modeling with SPSS/WIN 27.0 and Mplus 8.7. Results: The final model showed a good fit for the data. Children's media device addiction was directly related to mothers' self-esteem, mothers' marital conflict, and children's self-esteem. Fathers' self-esteem had a significant indirect effect on children's media device addiction by mediating both fathers' and mothers' marital conflict. In addition, mothers' self-esteem had a significant indirect effect on children's media device addiction by mediating mothers' marital conflict. Conclusion: The findings indicates that self-esteem and marital conflict for both fathers and mothers have a significant effect on children's media device addiction. It suggests that more attention might be given to fathers and mothers in developing interventions to prevent children's media device addiction.

This study investigated the impact of appearance pressure from celebrities' social media upon internalization of mesomorphic ideal and muscularity dissatisfaction and the moderating role of time spent on social media in the relationships among variables in a sample of young Korean men (N=247). Those men who regularly participate in physical activities more than three times a week were included in our sample. Structural equation modeling analysis revealed that celebrities' social media pressure directly influenced both internalization and muscularity dissatisfaction, and internalization predicted muscularity dissatisfaction. A significant mediating effect of internalization in the relationships between celebrities' social media pressure and muscularity dissatisfaction was found. However, the moderating effect of time spent on social media was not found. The present results highlight the significant and negative effects of celebrities' social media on male's body image perception. By comparing the results of this study to previous studies, we can anticipate that the effects of social media on users' body image concerns can differ between male and female in the matter of time spent on social media. Implications of the study results and suggestions for future studies are discussed.

The purpose of this study was to test the theoretical model designed to explain juvenile delinquency by media violence. Data were collected through questionnaire survey over a period of 3 months. Subjects served for this study consisted of 537 adolescents including 217 delinquent adolescents and 320 student adolescents in Korea, sampled from Korean student population and delinquent adolescent population confined in juvenile correctional institutions, using proportional stratified random sampling method. In this study, exogeneous variable was family dynamic environment and endogeneous variables were character of adolescent including need satisfaction/ frustration, sociability, antisocial personality tendency, complaints of psychosomatic symptoms and depressive trend, juvenile delinquent behavior and media violence themes including the extent of interest in and exposure and modelling impulsiveness and modelling to media violence themes. A total of 18 instruments were used to operationalized concepts in this model. A validation study indicated that internal consistencies for the 18 instruments which the researcher used were reliable. The one month test-retest correlation for these instruments ranged from 0.54 to 0.88. Statistical methods employed were descriptive statistics and covariance structural modelling. In summarized conclusion, it was found that media violence served as the most contributor to juvenile delinquency by direct effect of 0.64(t=10.18). That is, as the adolescents have to be the higher extent of interest in and exposure and modelling impulsiveness and modelling to media violence themes, they will show the more frequency of delinquent behavior. The single most powerful contributor by total effect of 0.73(t=7.90) (direct effect=0.19, indirect effect=0.54) to the development of delinquent behavior identified in this study was a construct defining family dynamic environment. That is, as the adolescents had to be more unstable family dynamic environment, they became more frustrated to their psychological need, and revealed the more maladaptive personality pattern, consequently they behaved the higher misconducts such as juvenile delinquency through media violence.

In this paper, we propose a 360 content pilot service platform of cultural assets based on MPEG-V standard realistic media testbed. MPEG-V is that the standard format of sensory effect metadata(SEM) such like wind, light and flash, and communication protocol between sensory effect machines are defined, and it is possible to increase the sense of presence and immersion with 360 VR content. The proposed platform consists of software which is composed of the content player and the sensory effect reappearance server, and hardware which is the sensory effect machines. Also, the pilot service case using the proposed platform, and the features and advantages of the proposed platform are described.

The expansion of the online market is expected to change the purchasing environment. The purpose of this study is to examine the difference in the moderating effect of each characteristic on perceived quality and purchase intention according to the group according to product involvement and purchaser age. The first step is to identify the characteristics of online information sources and social media platforms through a literature review. Next, when perceived quality affects purchase intention, we verify the moderating effect according to the characteristics of online information sources and social media platforms. The moderating effect is verified at the stage by dividing it into a group according to product involvement and a group according to age. The following results were confirmed throughout the study: First, perceived quality significantly affects purchase intention. Second, in the relationship between perceived quality and purchase intention, the influence of the moderating effect is different depending on the high-involvement product and the low-involvement product. Third, it was confirmed that there was a difference in the moderating effect of online information sources and social media platforms in the relationship between perceived quality and purchase intention according to age. This study intends to increase consumers' purchase intentions by identifying specific age groups and product groups of involvement and establishing strategies suitable for the characteristics of online information sources and social media platforms.

As the use of digital media is becoming more universal and is being used in early-childhood education, understanding the effects of digital media on development is required. The purpose of this study was to examine whether child performance on a spatial cognition task depends on the type of media used to present the task and if the effect of media type is different depending on child's age and sex. To do this, a spatial cognition task set (consisting of direction, rotation, symmetry, conjugation, and part/whole tasks) was prepared, and these tasks were presented to 60 3-, 4-, and 5-year-old children using paper- and tablet-based measures. Our results showed that the correct answer rate of task performance differed significantly when completing the task on a tablet than when completing the task on paper. Generally, response times when completing the tasks on a tablet was significantly shorter than when completing the tasks on paper. Although there was no interaction between the type of media and age, and partial interaction was found between the type of media and sex. This result implies an influence of digital stimulation on child performance on the spatial cognitive task. This study provides a basic understanding for follow-up studies to examine the consequences of exposure to digital stimulation.
