Despite the ever-increasing smartphone addiction of adolescents and a variety of consequent problems not much research has been conducted on the issue. It is time to prepare a set of countermeasures to protect them from the addiction. The central purpose of the current paper is to identify how use motives, self-control and social withdrawal affect their smartphone addiction. It was found (i) that the motives of information acquisition, social relationship, amusement and use of leisure time exert significant influence on smartphone addiction, (ii) that less self-control and greater impulsiveness result in greater addiction, and (iii) that social withdrawal of users also have significant effect on smartphone addiction. Such findings are expected to provide base data for any attempt to develop countermeasures against addiction. It is desirable that we had better check the play activities of adolescents and develop self-control programs to help them alleviate impulsiveness than simply impose strict restrictions on the use of smartphones.

This study defined the Creators who produce video contents related to Korean Wave in the form of one-person media and takes an influential role in China as the 'Korean Wave(Hallyu) Wanghong Media'. This study aimed at examining the effects of viewing motivation and behavior on satisfaction and cultural acceptance. The survey was conducted on 240 respondents who have watched the contents on China's Bilibili video site. As a result, among five different motivations, the higher the level of 'cultural curiosity', 'entertainment', and 'empathy', the higher the satisfaction. Examining the effect of viewing behavior on satisfaction, 'frequency', the act of 'sharing' and 'participating' had positive effects. Furthermore, 'cultural curiosity' and 'satisfaction' were the factors of positive influence on cultural acceptance. The results of this study can enhance the understanding of Korean Wave Wanghong Media and further contribute to continuous development.

In this paper, we propose the hierarchical network synchronization scheme that is backward compatible for the existing commercial system, efficient for total system performance, and whose hardware modification is minimized. This system performance is, the relationship among bandwidth efficiency, complexity and MODEM performance, and superiority of network system applicability. The proposed structure can remedy the high hardware complexity and the lower accuracy of network sychronization that the existing satellite communication terminal system in the star network based on TDM/MF-TDMA of DVB-S2/RCS standards has. Besides, It has high efficiency in view of cost and system performance if the system designed for satellite broadcast requires system upgrade. In the body section, its hardware complexity and system performance of the proposed algorithm is analysed theoretically and treated with the related parameters(symbol rate, spreading factor, etc.) and the BER performance of control channel through the computer simulation for its verification that it can be applied for communications system.

In Daesoon Jinrihoe (The Society of Daesoon Truth), pilgrimages can serve as a medium to experience and spread Daesoon Thought. The purpose of this study is to gauge the empirical impact that the motive of a pilgrimage has on the satisfaction level of the participant and the participant's willingness to revisit the holy place. This study further suggests a variety of propositions to promote pilgrimages and thereby Daesoon Thought. This study employs hierarchical analysis for measuring the correlation between all factors the pilgrimage can entail and also the moderator variables (holy places) in the pilgrimage. The study reveals that empirical motive is one of the most influential factors in determining a given participant's level of satisfaction and willingness to revisit said holy place. It is also revealed also that the religious significance of a holy place plays an important role in satisfaction and future revisitation. This study claims pilgrimages are a form of learning and cultural exchange which promotes Daesoon Thought that enables maturity of religious faith. Thereby, all stake holders in the Daesoon Jinrihoe community including clergy should increase their efforts to raise awareness and recognition of Daesoon Truth.

The purpose of the present study was to examine the relationships among private tutoring hours, academic motivation, use of learning strategies, and academic achievement test scores using structural equation modeling. The sample consisted of 3,607 7th graders from Korean middle schools who were included in the Korean Education Longitudinal Study. The results suggest that there was no evidence that the private tutoring hours predicted students' motivation and learning strategy use. It was found that the private tutoring hours predicted achievements in English and Math, but it was negligible in magnitude. As for achievement test scores, academic motivation and the use of learning strategies played more critical role rather than the private tutoring hours.

This study has examined the structural relationship among factors related to the effects of flipped learning using the structural equation modeling. Two hundred thirty-six middle school and high school students were participated in this study. This study's results are as follows. First, looking through how much the flipped learning variables affect achievement, motivation affects achievement the most, and then interaction, participation come next. Second, looking through how much the flipped learning variables affect personality, interaction affect personality the most, and then teaching attitudes come next. Third, as a result of verifying the research model, the hypothetical model indicating relationship among motivation, participation, teaching attitudes, interaction and achievement, personality is valid.

The web-based multimedia development tool was implemented to create and edit multimedia contents under the graphic user interface environment with icons. The development process enables the developers to verify the contents being developed by checking for errors, exchanging feedbacks and utilizing the pre-execution feature. By applying the tree structure to the internal data format, the tool uses inherent display features among media objects with time and spatial relations to efficiently process the synchronism of media objects that participate in the presentation and asynchronism according to user interaction.

This study was conducted to describe the relationship and influencing factors among college life adaptation, academic self-efficacy, and department satisfaction of freshman nursing students. There were 345 345 nursing freshman between November 30 and December 4 who participated in this study. The mean score of the college life adaptation, academic self-efficacy, and department satisfaction was $2.91({\pm}0.52)$, $2.79({\pm}0.60)$, and $3.55({\pm}0.47)$. The college life adaptation related with male group (p=.004), entering motivation (p=.027), friendship satisfaction (p<.001), first semester grade (p=.005), and academic self-efficacy related with male group (p=.040), entering motivation (p=.047), desired work (p=.015), friendship satisfaction (p=.014), first semester grade(p<.001), and department satisfaction related with entering motivation (p=.004), friendship satisfaction (p<.001), and first semester grade (p=.002) all showed statistical significance. There was a significant positive correlation among college life adaptation, academic self-efficacy (r=.223, p<.001), and department satisfaction (r=.342, p<.001). A significant and positive correlation was found between academic self-efficacy and department satisfaction (r=.218, p<.001). Department satisfaction was largely influenced by the college life adaptation. The regression model explained 23.1% of college life adaptation. In conclusion, this study showed that college life adaptation of freshman nursing students was correlated with academic self-efficacy and department satisfaction. Moreover, to increase the college adaptation of nursing freshman, it is necessary to develop educational programs to improve academic self-efficacy and department satisfaction.

This study investigates the link between music integration in the lives of adults in their twenties and their school music experiences. Ten individuals in their twenties were interviewed to explore their experiences based on the self-determination theory's fundamental psychological needs (autonomy, competence, and relatedness). Participants were categorized into an active music engagement group (5 individuals) and an inactive group (5 individuals) for individual interviews. Transcripts were analyzed following the five steps of grounded theory data analysis technique. Results indicated a strong connection between music activities during school years and current motivation for music integration, associated with the fulfillment of psychological needs outlined in the self-determination theory. Particularly, this study identified the instructional methods, school music activities, and performance evaluations as closely related to autonomy, competence, and relatedness. It offers a comprehensive analysis of how experiences in these areas during school music activities correlate with values and motivations for music integration in adulthood. Additionally, the study suggests ways to promote the voluntary incorporation of music into life through positive experiences of autonomy, competence, and relatedness in music activities.
