Purpose: This study examines the weight control behavior depending on university students' motives of using social media. Methods: The participants were 447 university students in the Jeonbuk area. Collected data were analyzed using factor analysis, cluster analysis, analysis of variance, and χ² tests with SPSS v. 26.0. Considering the motives of using social media, we investigated the usage of social media, dietary behavior related to social media, and weight control behavior. Results: Using the K-clustering method, the motives to use social media were categorized into three clusters: cluster 1 was the interest-centered group, cluster 2 was the multipurpose information-seeking group, and cluster 3 was the relationship-centered group. Among the various social media sites, YouTube (86.8%), Instagram (76.1%), and Facebook (61.1%) were the most visited by the subjects. The dietary behavior related to social media in cluster 2 was significantly higher than clusters 1 and 3 (p < 0.001). Clusters 1 and 2 showed a significantly higher dissatisfaction with one's weight (p < 0.05) and consequent interest in weight control than cluster 3 (p < 0.001). Cluster 2 used weight control-related information from social media significantly more than other clusters (p < 0.05). Weight control experiences in cluster 1 and 2 were significantly higher than in cluster 3 (p < 0.001). Conclusion: Differences in dietary behavior related to social media and weight control behavior were observed between cluster types of motivation to use social media. Based on the usage motives of university students and their behaviors, we propose that educational programs should be conducted for weight control using social media.

The purpose of this study is to examine problems and status quo of the smart media addiction prevention system and to develop convergence policies to improve those systems. Based on the literature review, notable results are as following; Since current facilities including Internet Addiction Prevention Center, Korea Youth Counselling and Welfare Institute, and I Will Center, tend to focus on restricting use of smart media, efforts from various ministries have not worked properly. Therefore, there needs to be more specified and customized services based on regions and ages. Following the precedent set by advanced countries, this study suggest alternative policies to help solving the problem including recommending responsible use of social media through education rather than regulations only, encouraging family participation and intervention, expanding harmful environment block system, and establishing a partnership between local government and private organizations under central government's control. Since smart media addiction is emerging concern, further researches will be needed for developing the Korean standard for prevention policy.

The purpose of this study was to explore the reasons why college students use Facebook and the ways in which they feel of social presence while using Facebook. In fact, the study aimed to specify the links between motivations for using SNS and a sense of 'being together'. The findings of this study suggest that major motivations of SNS use were social interaction, entertainment, self-presentation, and information-seeking. Specifically, results from a survey of 280 respondents revealed that college students used Facebook to seek maintenance and connection with friends, to express themselves, to get information about school activities, and to be entertained. These findings are consistent with the existing literature regarding SNS as a primary channel to maintain the existing social relationships among college students. The study also found that all motivation factors, except information-seeking factor, were positively and significantly related to social presence. The strongest correlations were between social presence and Facebook use for social interaction and entertainment needs. It seemed that users who seek social interaction and entertainment needs are more likely to feel a sense of being with others while users who seek to get information are less likely to feel a sense of social presence. These findings implied that to some extent, a sense of social presence occurs in the context of Facebook and that the experience of social presence depends on what college students seek from Facebook use. In addition, the results showed a positive relationship between Facebook use and social presence; the more college students use Facebook, the more they are likely to experience sense of social presence. Given that Facebook provides college students with a place where they can share thought and feelings among friends, it can be concluded that Facebook contributes to the sense of belonging among users. And such feeling may enhance a sense of presence with others while using Facebook. These findings suggest that uses and gratifications researchers should consider the concept of social presence as an important variable in explaining what audience members do with media.

With the development of social media services in the era of Web 2.0, the public opinion formation site has been partially shifted from the traditional mass media to social media. This phenomenon is continuing to expand, and public opinions on government polices created and shared on social media are attracting more attention. It is particularly important to grasp public opinions in policy formulation because setting up educational policies involves a variety of stakeholders and conflicts. The purpose of this study is to explore public opinions about education-related policies through an empirical analysis of social media documents on education policies using opinion mining techniques. For this purpose, we collected the education policy-related documents by keyword, which were produced by users through the social media service, tokenized and extracted sentimental qualities of the documents, and scored the qualities using sentiment dictionaries to find out public preferences for specific education policies. As a result, a lot of negative public opinions were found regarding the smart education policies that use the keywords of digital textbooks and e-learning; while the software education policies using coding education and computer thinking as the keywords had more positive opinions. In addition, the general policies having the keywords of free school terms and creative personality education showed more negative public opinions. As much as 20% of the documents were unable to extract sentiments from, signifying that there are still a certain share of blog posts or tweets that do not reflect the writers' opinions.

This research observes how an adolescent's usage of social network services is related with media use time, and also tries to verify how a parent's participation in acting to limit usage time serves as a mediating effect. For this analysis, data from The Korean Information Society Development Institute [Korea Media Panel Research] was used, being a survey conducted on 1,572 students from primary to secondary and high schools nationwide. The subjects' gender in the final analysis was 818 male students and 754 female students. In addition, primary school students consisted of 672 individuals, 416 were from secondary and 484 from high schools. To verify the appropriateness of the model proposed in this research, analyzed through the structural equation, using social network services(SNS) was not shown to have an effect on media usage time. However, there was an indirect effect from the use of alternative activities. In addition, the parent's limitation of usage showed no effect on media use time. This research attempts to identify the reasons why parents' limiting the usage time, along with alternative activities, do not have any significant effect in reducing media usage time in this era of smart media evolution. Further, this research hopes to suggest meaningful and political implications for the nation and society to understand and resolve media addiction.

The purpose of this study is to understand the social and cultural implication of the activities of taking 'selfies' and the use of Social Network Service(SNS)s through the personal story of a 20s female researcher. She analyzes her own digital photography activities based on the experience of the use of Cyworld photo albums for three years and the use of pictures in iPhone album for fifteen months. The other researcher(40s male) cooperates to answer the questions about how to understand the digital photography activities. We understand the digital photography activities including digital cameras, social network services and smart phones as acts of personal identity configuration and acts of making the personal documentary. As a result, digital photos are used more for archive purpose rather than for document purpose. Also, we found that the digital photography activities can be understood as the interactions between human and non-human actors in the perspective of Actor-Network Theory (ANT).

Purpose: This study aimed to analyze the mass and social media contents and structures related to particulate matter before and after the policy enforcement of the comprehensive countermeasures for particulate matter, derive nursing implications, and provide a basis for designing health policies. Methods: After crawling online news articles and posts on social networking sites before and after policy enforcement with particulate matter as keywords, we conducted topic and semantic network analysis using TEXTOM, R, and UCINET 6. Results: In topic analysis, behavior tips was the common main topic in both media before and after the policy enforcement. After the policy enforcement, influence on health disappeared from the main topics due to increased reports about reduction measures and government in mass media, whereas influence on health appeared as the main topic in social media. However semantic network analysis confirmed that social media had much number of nodes and links and lower centrality than mass media, leaving substantial information that was not organically connected and unstructured. Conclusion: Understanding of particulate matter policy and implications influence health, as well as gaps in the needs and use of health information, should be integrated with leadership and supports in the nurses' care of vulnerable patients and public health promotion.

The purpose of this study is to explore the digital divide that appears in the mobile Internet use by farmers and fishers. To this end, we first analyzed the impact of farmers and fishers' attitudes toward technology, material access, and skills on the use of mobile social media. In addition, the digital divide was identified according to the population, socioeconomic factors among farmers and fishers, and the divide and the cause of the mobile Internet use among both part- and full-time farmers and fishers were analyzed. As a result of empirical analysis using the <2018 Report on the Digital Divide>, attitudes, material access, and content-related skills had a significant effect on the use of mobile social media. Also, the digital divide was found in different age groups and residential regions. There was also a significant difference in the use of mobile social media between part- and full-time farmers and fishers, and this divide was caused by attitudes toward new technologies. Based on these results, this study presented policy implications such as the need for education on informatization for farmers and fishers, support for underdeveloped rural communities, and technical support for full-time farmers and fishers in order to bridge the digital divide.
