Data were collected during June in 2009. Statistical analysis used in this study were frequency, F-test, t-test, Duncan test, factor analysis, Cronbach's ${\alpha}$, correlation coefficient, and multiple regression. The results of this study were as follows. The mass media according to the demographic characteristic of women showed significant difference. Three factors of clothing image were titled as elegance, youth, and visibility. Three factors of make-up image were titled as modern, romanticism, and mediocrity. Four factors of hair image were titled as attraction, individuality, gentleness, and cuteness. The mass media resulted in correlation with the clothing image, make-up image, and hair image.

Recently, as the number of smart-phone users has been rapidly increased, enterprise managers have a keen interest in business application of social media. Most previous studies have focused on perspective of the individual unit of analysis instead of enterprise level unit. The study is focused on the relationship between the enterprises' recognition and behavioral intention (and use) about social media application. The purpose of this study is to develop the model of small and medium enterprises' social media application, and to find the factors affecting their behavioral intention or use behavior. The moderating effects of four corporate characteristics on the relationship between the enterprises' recognition and behavioral intention are also examined. We surveyed 900 corporate staffs and received 203 responses. After questionnaires with unreliable responses had been excluded, 182 effective samples were used in the final analysis. The findings suggest that Performance Expectation, Social Influence, Facilitating Conditions significantly affect Behavioral Intention of social medea, and Behavioral Intention affects USE. Furthermore, some corporate characteristics have moderating effect on the relationship between recognition of social media and Behavioral Intention.

In vitro culture of murine embryos is an important step for in vitro production systems including in vitro fertilization and generations of genetically engineered mice. M16 is widely used commercialized culture media for the murine embryos. Compared to other media such as potassium simplex optimization medium, commercial M16 (Sigma) media lacks of amino acid, glutamine and antibiotics. In the present study, we optimized M16 based embryo culture system using commercialized antibiotics-glutamine or amino acids supplements. In vivo derived murine zygote were M16 media were supplemented with commercial Penicillin-Streptomycin-Glutamine solution (PSG; Gibco) or MEM Non-Essential Amino Acids solution (NEAA; Gibco) as experimental design. Addition of PSG did not improved cleavage and blastocyst rates. On the other hand, cleavage rate is not different between control and NEAA treated group, however, blastocyst formation is significantly (P<0.05) improved in NEAA treated group. Developmental competence between PSG and NEAA treated groups were also compared. Between two groups, cleavage rate was similar. However, blastocyst formation rate is significantly improved in NEAA treated group. Taken together, beneficial effect of NEAA on murine embryos development was confirmed. Effect of antibiotics and glutamine addition to M16 media is still not clear in the study.

Purpose: The purpose of this study was to find the factors influencing adolescents' adult media engagement. The study is based on Agnew's General Strain Theory (GST) and a micro-systemic perspective. Methods: The study examined 479 middle school freshmen who participated in the fourth wave of the Korean Children & Youth Panel Survey (KCYPS) conducted by National Youth Policy Institute. Data were analyzed through descriptive statistics, factor analysis, and reliability analysis using SPSS 22.0 Ver. Also, hypothesis testing was performed via covariance-based structure equation modeling (CB-SEM) using Amos 21.0 Ver. Results: Strain factors had positive effects on adolescent depression, and depression had a positive effect on adult media engagement. Also, cell-phone dependency had a positive mediation effect between depression and adult media engagement. Conclusion: The study's result identified the factors affecting adult media engagement. Therefore, we suggest intervention programs considering adolescents' strains, depression and cell-phone dependency to improve their health.

This study drew the reason of the limitation in low-carbon city plan from a absence of 'social sustainability' and supplemented its limitation by suggesting the new concept of city facility called Green Media. It clarified the concept of Green Media, and analyzed its effect on low-carbon city plan based on the analysis of related cases inside and outside the country. This study made an important step forward in introducing the new concept to complement social sustainability, analyzing its effect, and suggesting the applicable details.

Objective: The purpose of this study was to explore the structural relationships among duration of media use, behavior problems, and school adjustment, while accounting for gender differences. Methods: The study used 4th-wave panel data from the Korean Children and Youth Panel Study, and 2,119 first graders in elementary school were analyzed. The data were analyzed using Structural Equation Modeling. Results: The results can be summarized as follows. First, the duration of media use had a direct effect on school adjustment. Secondly, the duration of media use had an indirect effect on school adjustment through internalizing and externalizing problems. According to multigroup analysis, gender differences were found in the structural relations among variables. Conclusion: This study emphasizes the needs for media usage education to improve children's school adjustment. Furthermore, it suggests that different intervention strategies for internalizing/externalizing behavior problems are needed depending on gender.

Immobilization technique by PVA encapsulation is an effective alternative for wastewater treatment. However little information is available about the effect of PVA characteristics on physical properties as an encapsulation media. This study aims at investigating the effect of the preparation methods of PVA and filler addition to media on the solubility of PVA. The solubility decreased as the freezing temperature decreased and the vacuum-drying was applied. Addition of the PAC (Powered Activated Carbon) and organoclay decreased the solubility of the PVA gels. Organoclay was more effective for lowering the solubility about 25% than the PAC. Nitrification with the PVA-coating media was less sufficient than with the polyurethane media due to the mass transfer restriction for oxygen and nutrients.

The purpose of this study was to extend the social comparison theory in an attempt to examine the effect of TV media on adolescent body images. The research was a survey and the subjects were 895 male and female adolescents in Taejon, Korea. The measuring instruments were 2 sets of stimuli of male and female body silhouettes and self-administrated questionnaire. Results were as follows: 1) The subjects TV viewing periods were 3∼4 hours per day and their involvements in TV media were moderate degree. 2) The results of perceptual body images showed that adolescent favored thin body type as an ideal body and had distorting tendency that their bodies were larger than the actual sizes. 3) The results of attitudinal body images showed three factors such as \"appearance evaluation\", \"appearance orientation\", and \"fitness orientation\". 4) TV media had significant effects on perceptual and attitudinal body images. It is concluded that the results of this study support social comparison theory that people compare themselves to others to satisfy their needs for self-evaluation and for judgments of their own personal worth since TV media give strong influence on adolescents through presenting social comparison models to body images.
