This study examines the effects of mass media, the tendency for young women to make body comparisons, and the BMI of female high school and college students on their attitudes about eating. Participants were 392 high school students from Gyeonggi Province and 391 college students from Seoul, Gyeonggi and Chung-nam Province. Collected data were analyzed through Cronbach's ${\alpha}$, t-test, One-way ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation, and stepwise multiple regression. The findings of the study were as follows: 1) While mass media influence differed by grade, tendency for appearance comparison and attitude toward eating did not differ by grade. 2) Mass media influence, tendency for appearance comparison and attitude toward eating differed by BMI. 3) Mass media pressure, specific attributes comparison, and BMI were significant predictors of attitudes toward eating. 4) Tendency for appearance comparison played a mediating role in the relationship between mass media and attitudes toward eating.

The purpose of this study was to identify the relationships among self-esteem, physical appearance comparison, media concern, sociocultural attitude toward appearance, body attitudes, and life satisfaction. Data were collected from a convenience sample of 232 female undergraduate students. Data were analyzed using factor analysis, correlation, and multiple regression. The result showed that there was a correlation between physical appearance comparison and media concern. Self-esteem, physical appearance comparison, and media concern had an indirect influence on body attitudes through sociocultural attitude toward appearance. Self-esteem and physical appearance comparison had a direct effect on body attitude. All variables did not have an influence on life satisfaction, except self-esteem.

Previous research has empirically demonstrated the negative effects of social media use on young people's psychological well-being. Unlike most previous studies that focused on either Facebook or Instagram, this study comparatively examined the differences in upward comparison and its effects on self-esteem, life satisfaction, and depression between Facebook and Instagram. An analysis of survey data from 641 Korean college students, who reportedly use these two social media more actively than any other age group, found that college students experience more upward comparisons on Instagram than on Facebook. Upward comparisons on both Facebook and Instagram increased by college students' age and weekly usage time. Upward comparisons on Instagram increased by the additional factors of gender (females more than males) and number of "followings." Subsequently, the effects of upward comparison on psychological well-being were found to differ by social media platform. Upward comparisons were found to negatively impact all determinants of psychological well-being only on Instagram, but not on Facebook. The differences in upward comparison and its impact on young users' psychological well-being found in this study were discussed in terms of the different functional characteristics of the two social media platforms, which provides direction for further research needed to establish guidelines for healthy social media use by young people.

On the basis of two premises and embodied cognition theory, the vibration tactile learning is proposed as an effective method for foreign language learning. The premises are: the real nature of language is sound and the source of sound is vibration. According to embodied cognition theory, cognition is inherently connected to bodily sensation rather than metaphysical and independent. As a result, the vibration tactile learning is: people are able to learn foreign language better by listening to sound and experiencing its vibration through touch rather than solely listening to sound. The effectiveness of vibration tactile learning is tested with two instructional media theories: media comparison and media attribute. For the comparison, an experiment is conducted with control and experimental groups. The attributes of vibration tactile media are investigated in points of relationships with the learning process. The experiment results indicate a small effect on the increased mean score. Three kinds of relationships are found between the media attribute and learning process: enforced stimulus, facilitated pronunciation, and assimilation of resonance to sound patterns through touch. Finally, this paper proposes a new theoretical development for instructional media research: an embodied cognition based media research and development.

Social media is an essential part of everyday life in modern society and plays an important role in communicating the ideal body image. With the increased prevalence and high popularity of social media, the problems associated with the addictive use of social media have become a social issue. Utilizing social comparison theory, this study examined (1) the effect of appearance related photo activities on body satisfaction through appearance comparison and (2) the moderating effect of Instagram addiction in relationships among appearance related photo activity, appearance comparison, and body satisfaction. We tested the proposed relationships between research variables using multi-group structural equation modeling analysis on a sample of 346 young female Instagram users. The sample was divided into two groups of high and low addicted Instagram users. The results of this study showed that the appearance related photo activity positively influenced appearance comparison for both high and low addiction groups. For the high addiction group, the effect of appearance comparison on body satisfaction was not statistically significant; however, this relationship was significant and negative for the low addiction group. A significant moderating effect of Instagram addiction was found in the relationship between appearance related photo activity and appearance comparison.

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.

This study compares the performance of the filters with various media in pretreatment of seawater desalination by reverse osmosis. For this purpose, Masan bay seawater is used as raw water. The filter performance is evaluated by the filtrate quality and the head loss development. Five media is selected in this study: anthracite, $Filtralite^{(R)}$, sand, Pumice, $AFM^{(R)}$. These media are used in combination for dual media filter and alone for mono media filter. The comparison results show that NC0.8-1.6 is the best $Filtralite^{(R)}$. The dual media filter of NC0.8-1.6 and sand outperformed other filters in particle removal. The dual media filter of anthracite and sand showed good performance in organic removal. The mono media filter of Pumice produced the similar filtrate quality as the mono media filter of sand although the effective size of Pumice is considerably greater than that of sand. Due to big size, head loss development is maintained slow in the filtration of Pumice.

Electronic word-of-mouth (eWOM) in social media has been recognized as one of the most influential marketing tools across various businesses. Understanding eWOM in social media is critical to reach potential global consumers easily and quickly in the hospitality industry. However, few empirical studies in hospitality attempted to evaluate the effectiveness of eWOM in social media from a global perspective. Given the competitive climate of the hospitality market, it is meaningful for hospitality marketers to evaluate the effectiveness of eWOM in social media and the influence of cultural factors to promote customers and increase profitability globally. The main purpose of this study was to examine the influence of cultural values on social media eWOM in the hospitality industry in China, Korea, and the USA. The result of this study indicates Chinese and American people engage more than Korean people when they try to purchase hospitality product and service This study particularly provided a cross-cultural study of comparison among these countries and the findings of this study are expected to provide important practical assistance for global marketing strategies in social media.

To evaluate which dye is effective in a plate assay for detecting extracellular cellulase activity produced by fungi, four chromogenic dyes including remazol brilliant blue, phenol red, congo red, and tryphan blue, were compared using chromagepic media. For the comparison, 19 fungal species belonging to three phyla, ascomycota, basidiomycota, and zygomycota were inoculated onto yeast nitrogen-based media containing different carbon substrates such as cellulose (carboxylmethyl and avicel types) and cellobiose labeled with each of the four dyes. Overall, the formation of clear zone on agar media resulting from the degradation of the substrates by the enzymes secreted from the test fungi was most apparent with media containing congo red. The detection frequency of cellulase activity was also most high on congo red-supplemented media. The results of this study showed that congo red is better dye than other three dyes in, a plate assay for, fungal enzyme detection.
