This study aims to investigate the awareness and experiences of domestic researchers regarding data publishing, which has been recognized as a new channel of data sharing as scholarly communication evolves in the open science environment. A survey is conducted among researchers from five government-funded research institutes in the field of science and technology and members of the GeoAI Data Society to confirm the awareness of data publishing. As a result of the study, domestic researchers recognized providing explanations for data, stable access to data, citation, and quality assurance through peer review as the advantages of data journals. On the contrary, a low level of recognition for data paper as one of the research outputs was presented. With regard to the properties of data publication, the respondents answered that the data description, metadata description, and permanent identifiers are highly related, however, their recognition of the relation between the properties of data publication and the data submission to a repository and data peer review was relatively low. Finally, to expand the data publication, the need for the development of an editorial system that supports data paper peer review and cross-linking to a data repository as well as the development of a repository that supports data citation was identified. This study on the domestic researchers' experience and awareness of data publishing can provide insights for the implementation of data publishing services and infrastructure in the future.

This study was intended to investigate predictability among variables having an effect on problem solving skill and achievement in collaborative learning by utilizing SNS at university. To this end, 61 first-year students majoring in early childhood education at I community university in the national capital region were surveyed. And on the basis of the collected data, a multiple regression analysis was carried out. The results of carrying out the analysis are as follows. First, it was shown that self-efficacy, peer learning and help seeking had a significant effect on problem solving skill, and explained 70 of variability in problem solving skill. Second, it was shown that peek learning, help seeking and problem solving skill significantly predicted achievement, and explained 72% of the variability in achievement. Third, problem solving skill partially mediated the relationship between self-efficacy and achievement. The above-mentioned results imply that learning motivation should be increased so that learners have self-efficacy in order to improve college students' academic achievement in collaborative learning by utilizing SNS at university, and a class environment making it possible to actively provide peer learning and help seeking should be designed and a specific scheme enabling the enhancement of the problem solving skill should be considered.

As an important basic building block of the smart grid environment, smart meter provides real-time electricity consumption information to the utility. However, ensuring information security and privacy in the smart meter data aggregation process is a non-trivial task. Even though the secure data aggregation for the smart meter has been a lot of attention from both academic and industry researchers in recent years, most of these studies are not secure against internal attackers or cannot provide data integrity. Besides, their computation costs are not satisfactory because the bilinear pairing operation or the hash-to-point operation is performed at the smart meter system. Recently, blockchains or distributed ledgers are an emerging technology that has drawn considerable interest from energy supply firms, startups, technology developers, financial institutions, national governments and the academic community. In particular, blockchains are identified as having the potential to bring significant benefits and innovation for the electricity consumption network. This study suggests a distributed, privacy-preserving, and simple secure smart meter data aggregation system, backed up by Blockchain technology. Smart meter data are aggregated and verified by a hierarchical Merkle tree, in which the consensus protocol is supported by the practical Byzantine fault tolerance algorithm.

Objectives: The major objectives of this study are to review the U.S. Standard which affected Korean worker's Right-to-Know Standard and to propose the way of improving the reliability of MSDS and labels. Methods: To review the U.S. Standard historically, we used the Federal Register, other criteria documentation and peer-reviewed literatures. Then we analysed major issues in the historical debatement on the worker's Right-to-Know Standard. Results: Korean MSDS Standard benchmarked the U.S. Hazard Communication Standard which finally established by President Reagan in 1983. Reagan's Hazard Communication Standard was aimed to preempt States Right-to-Know Acts for chemical industry and not to improve the awareness of workers on chemical hazards. Too much protection on trade secrets and low reliability of hazard information were key problems of the U.S. Standard. Conclusions: We recommend some ways to improve Korean MSDS and Label Standard. First, A new analysis frame is needed to understand the U.S Standard. Second, hazard identification is the key element of reliable information and chemical name and CAS number should be on the label of the container. Third, trade secrets should be limited to low hazardous substances and be permitted by government before the chemical product is on the market.

This study problematizes the youth‘s politico-cultural process of identification as becoming in the context of candle demonstration in Seoul, 2008. We examine their ethical subjectivity, communicative subjectivity and political subjectivity based on our analysis of depth interviews of teenage activists in the candle demonstrations. It is suggested that instead of naming the teens as the historical consequence of so-called 386 generation, or social product in the neo-liberal economic and educational conditions, we need to understand the complexities and dynamics of the youth’s practice of identity politics: subjective pain and anxiety in daily life, creation and sharing of pleasure and fun of peer group comunication are mixed into the pursuit of justice in their social activation of generation/gender politics.

With the development and popularization of Internet, the competition of SNS market is now getting fiercer and fiercer. SNS service providers need to keep updating their service to sustain their customers' continuance use. However, due to the homogenization of functions and services from different applications provided by different developers, there comes a new phenomenon that users shift from one SNS to another SNS. In line with this, the current study aims to explore factors affecting switching intention among SNS users by applying migration theory which explains people's migration behavior from one place to another. Findings from surveys of Korean and Chinese college students suggest that there was a difference of factors influencing switching intention among the two countries. For Korean college students, alternative attraction was the strongest factor leading to SNS switching intention. On the other hand, peer pressure was the strongest factor leading to SNS switching intention among Chinese college students.

The current study examined the relationships between the adolescent's conflict resolution style and Big-Five personality factors, self-monitoring and self-esteem. Firstly, results showed that adolescent's big-five personality model affects their conflict resolution styles with their friends and peer group. In detail, the higher the neuroticism was, the stronger became the attack and avoidance strategies. The higher the extraversion was, the higher became the collaborative strategy and the lower became the attack and avoidance strategies. The higher the agreeableness was, the higher became the collaborative strategy and the lower became the attack strategy. The higher the conscientiousness was, the higher became the collaborative strategy and the lower became the avoidance strategy. The higher the openness to experience was, the higher became the collaborative strategy and the lower became the avoidance strategy. The higher the self-esteem was, the higher became the collaborative strategy and the lower became the avoidance and attack strategies. The higher the self-monitoring was, the higher became the collaborative strategy and the lower became the avoidance strategy. Secondly, the big-five personality factors also affected the adolescent's conflict resolution styles. The extraversion, conscientiousness, and agreeableness positively affected the collaborative strategy. The neuroticism was positively related with the attack strategy, whereas agreeableness was negatively affected the attack strategy. The neuroticism and agreeableness were positively related with the avoidance strategy, whereas the extraversion was negatively affected the avoidance strategy. Limitations and suggestions for future study were discussed thereafter.

This study investigated the integrated effects of family and school factors on the cyber behavior of adolescents. Specifically, the purposes of this study were to categorize adolescents into groups by family and school factors and to find investigate differences among the groups regarding cyber behavior (internet use, internet purpose, and internet experience). no study distributed the questionnaires to middle and high school adolescent students of five representative cities in South Korea. The total respondents were 2240 (960 from Seoul/kyongki, and 320 each from Taegu, Pusan, Kwangiu, and Taejon). The response rate w3s 98.7%. no data were analyzed by factor analysis, cluster analysis, ANOVA, and Duncan test. The results showed that Korean adolescents were segmented into four groups (family preference/school preference group, family dissatisfaction/teacher dissatisfaction group, family average/school average group, family average/peer dissatisfaction group). The four groups were significantly different in regard to cyber behavior. For example, the family dissatisfaction/teacher dissatisfaction group u%d internet to relieve stress and used communication more than the other groups. Also, the group had more diverse cyber behavior including internet addiction. The implications of the study were further discussed.
