This study was conducted to investigate the correlation between frequency of high-caffeine energy drink intake in adolescents and their mental health status using data from the Korean adolescent health behaviors online survey (2014-15). Mental health was classified by the five categories: Perception of stress (PS), Insufficient relief of fatigue after sleep (IRFS), Experience of sadness despair (SD), Suicidal ideation (SI), and Subjective unhappiness (SU). Regarding general characteristics, higher age, height, and body weight of subjects were associated with higher frequency of high-caffeine energy drink (HCED) intake (p< .0001). In the OR analysis, when the lowest group (${\leq}2/wk$) and highest group ($1{\geq}day$) were compared, the highest group showed significantly higher OR in all five categories of mental health. According to gender, males did not show better PS, SD, and SI than females who had a high frequency of HCED (p for trend<.0001). According to school level, middle school students showed a higher risk rate than high school students in PS, IRFS, and SD (p for trend< .0001). Based on the above results, higher frequency of HCED intake among adolescents was associated with more adverse effects on mental health.

As collaborative computing technology goes widespread, interactions among concurrent users are very important, especially in education domain. But existing co-authoring mechanisms and CSCW technologies have limitations for conflict handling. In general, co-authoring tools provide solutions that one or certain users' views are influenced for conflict handling. These solutions have advantages to accomplish rapidly for conflict handling, but other authors' views cannot be affected sufficiently. In this paper, we define the courseware as network structure of instructional units. And we propose co-authoring model for courseware using collaborative conflict-handling mechanism. Using this mechanism, instructors can affect their own viewpoints to the unique courseware. As contents created in these forms have multiple structures. it can provide proper materials according to students' requirements. Therefore, it can provide students with individual learning facilities on online educational systems. Proposed model is useful for courseware based on structured form of document such as XML.

It is very active that existing companies of providing e-Learning contents try to differentiate themselves through a business model based on Web 2.0. For instance, Etoos, online education website (www.etoos.com) run by SK Communications has made more space where students can participate in the Web 2.0 era and overhauled its website completely, turning into an open-ended one, which strengthens learning and fun in 2007. This study is to analyze the present state of e-Learning contents with representative e-learning sites for middle and high school students, to find that the development direction for next generation e-Learning lies in developing contents focusing on learners that can get effective feedback and drawing collective intelligence grounded on the essence of Web 2.0, and to suggest 'the project to form virtual private tutor community in e-Learning contents.'

This study intends to provide foundational data for enhancing the welfare of customers purchasing digital products through analyzing the notes from written on-line reviews. The data used for the analysis are 6,342 on-line reviews for cell phones and digital cameras released from November, 2007 until April, 2008, which was posted on Naver Knowledge Shopping from November, 2007 until June, 2008. Through the on-line reviews, this article analyzed the evaluations on the digital products' hardware, software, design, service, price, and other criteria and the customers' emotional experience in the process of purchase, use, and possession. According to the results of the analysis, negative evaluation and emotional experience were originated from the company's information provision methods and purchase process. In addition, insufficient information searches in the process of online purchases, consumers' low right consciousness, and impolite on-line reviews were also problematic. Customers' evaluations and emotional experiences on digital products were conducted in a complex way. Based on that, this research makes suggestions in the company's marketing, customer education, and theoretical aspect.

The development in information technology resulted in an interest for lifelong education, which caused a rapid growth in the educational web based e-Iearning industry. The spread of e-Iearning industries and educational facilities emphasized the need for educational contents with the purpose of online lecturing along with the rapid development of contents production technology. Flash contents provide multimedia, animation, and etc. with diverse and visual expressions, so the complicated interactions with the learner can be easily materialized. The advantage of having a high quality, user-centered interface is that it provides a trigger of interest and arousal of concentration for the user, but it is difficult for teachers to directly create or manipulate educational flash animation contents. This paper is written to technologically methodize the automation of educational programs that the teachers wish to make by reusing the educational flash animation contents.

Purpose: The study was done to explore relationships between residential areas and smoking rates and to identify related factors contributing to smoking in Korea adolescents. Methods: An analysis was done of smoking rates and socioeconomic position indicators by city size based on a 2012 cross-sectional nationwide online survey conducted with 74,186 Korean middle and high school students aged 12-18 years old. Data were analyzed using x2-test and multiple logistic regression with the SPSS/WIN18.0 program. Results: Analyses revealed that rural boys were more likely to be current smokers compared to metropolitan boys (odds ratio 1.18, 95%-confidence interval 1.01; 1.38) but residential areas and smoking rates among girls were not related. After adjusting for covariates, results showed that city size, Family affluence score, economic status, parents' education level, living with parents, school type, and school achievement were related to increased an proportion of adolescents who smoked. Conclusion: In conclusion, rural living is a determinant of smoking among boys. Tobacco control programs should recognize differences in living conditions between rural and urban areas.

Purpose : The purpose of this study was to review mobile health (mHealth) interventions based on studies from online databases for community-dwelling patients with heart diseases. Methods : Six databases (RISS, KISS, PubMed, CINAHL, EMBASE, and SCOPUS) were searched to select studies conducted from January 1 to September 30, 2010. After this, quality appraisals were carried out using the Scottish Intercollegiate Guidelines Network checklist and a total of 11 studies were selected. Results : The selected 11 studies included 7 randomized controlled studies, 1 quasi-experimental study and 3 pilot studies. The main components of mHealth interventions included symptom monitoring at home, provisions for individualized messages for health management using text messaging, telephone or smart phone applications, and running websites for symptom monitoring or health education. Intervention periods varied from 6 weeks to 12 months. The findings of the studies suggested that the mHealth interventions were effective in improving self-management of heart diseases, quality of life, and decreasing symptoms. Conclusions : The results of the review suggested that mHealth interventions had positive effects on community-dwelling patients with heart diseases. More mHealth intervention studies need to be conducted in Korea to aid community-dwelling patients with heart diseases.
