With the development of Internet and popularization of smartphones over recent years, social network services are experiencing rapid growth. On top of this, smartphone gaming market is showing a rapid growth and the use of mobile social games is on the significant rise. The occurrence of game data manipulation targeting these services and personal information leakage is highlighting the importance of social gaming security. This study is intended to propose development plans effective and efficient in social game services by figuring out factors putting effects on security dependent behavior of social game users in Korea and carrying out a practical study on the casual relationship between factors influencing security dependent behavior through recognized behavioral control and attitudes for privacy infringement of these factors. To do this, proposed was a study model in which the HBM(Health Belief Model) allowing the social game user to influence security dependent behavior was expanded and applied as a major variable. To verify the study model of this study practically, a survey was conducted among university students in Seoul-based K University and S University who had experienced using social game services. According to the study findings, firstly, the perceived seriousness turned out to provide positive influence to trust. But, the perceived seriousness turned out not to put positive effects on self-efficacy. Secondly, the perceived probability turned out not to put positive effects on self-efficacy and trust. Thirdly, the perceived gain turned out to put positive effects on self-efficacy and trust. Fourthly, the perceived disorder turned out not to put positive effects on self-efficacy and trust. Fifthly, self-efficacy turned out to put positive effects on trust. But, self-efficacy turned out not to put positive effects on security dependent behavior. Sixthly, trust turned out not to put positive effects on security dependent behavior. This study is intended to make a strategic proposal so that social game users can raise awareness of their level of security perception and security willingness through this.

This study focused on whether employees' perceived leader's creativity has a significant effect on employees' job satisfaction and innovative behavior. In addition, this study analyzed the mediating effect of positive psychological capital and creative self-efficacy in the relationship between perceived leader creativity and employee satisfaction with the job or innovation behavior, and analyzed the moderated mediating effect of team cohesion. This study conducted confirmatory factor analysis and path analysis for each factor using the measurement tool verification method using the SmartPLS 3.0 structural equation model, and empirically analyzed the research model. As a result, it was found that the creativity of employees' perceived leaders did not directly significantly affect employees' job satisfaction and innovation behavior. However, it was found that positive psychological capital significantly mediated the relationship between perceived leader creativity and job satisfaction or innovative behavior. In addition, positive psychological capital and creative self-efficacy have a complete double-mediation relationship between the employees' perceived leader's creativity and employees' innovative behavior. However, positive psychological capital and creative self-efficacy don't have a double-mediation relationship between the employee's perceived leader's creativity and employees' job satisfaction. Finally, Team cohesion was found to moderate the relationship between perceived leader creativity, positive psychological capital (or creative self-efficacy). However, the research model that the moderated mediating effect of team cohesion on the relationship between leader's creativity, the mediating variables(positive psychological capital and creative self-efficacy), and job satisfaction (or innovative behavior) was significant only for groups with high team cohesiveness. This study examined the needs of the times for the importance of creativity of perceived leaders and analyzed the relationship between factors influencing job satisfaction and innovation behavior of organizational members. The study is meaningful in that it suggested a plan to establish a specific organizational strategy to enhance positive psychological capital and creative self-efficacy.

Plate tectonics, with the continental drift theory and later strongly supported by the sea-floor spreading theory with evidence of paleo-geomagnetic fields, ocean floor sediments, successfully explained the slow but continuous movements of rigid lithospheres in geological time. Initially, plate motions were described as relative movements between adjacent plates, mainly based on paleo-geomagnetic reversal data. The advent of space geodetic techniques in the 1980s enabled direct measurements of plate velocities and assessment of deformations within certain regions. In this review, early relative plate motion models are briefly summarized, the no-net-rotation frame theory and corresponding models are explained, and the characteristics of the most recent models that incorporate intraplate deformation are described. Additionally, the plate motion section of the International Terrestrial Reference Frame is introduced, and a few recent case studies of local plate motion are briefly described; for example, in South America, Europe, Antarctica, and Turkey. Finally, studies of plate motion in northeastern Asia focusing on the Korean Peninsula are introduced.

The e-Book market has rapidly grown as an innovative product which is mixed its traditional and technological characteristics. However, decreasing user resistance to the e-Book is very important to continually keeping up its market growth. Previous studies for user resistance have been studied as a negative barrier for various innovative products with importance of user resistance. Nevertheless, the factors for user' resistance to the e-Book field have not been found out considering both perceived value and switching cost. Especially, both innovative technology and user specifics should be considered when explaining user resistance to adopting e-Books. Thus, the purpose of this study is to understand the process for user resistance to the e-book and find out its antecedents with perceived value and switching cost at the same time. As a result, it appeared that triability, uncertainty and complexity affected perceived value and switching cost. The user-based antecedents like social norm and perceived value increased the effect of self-efficacy. Also, self-efficacy and perceived value decreased user resistance whereas switching cost increase user resistance to the e-Book perspective.

The objective of this study was to analyze the factors affecting the stages of change of exercise in middle-aged men who work. 170 middle-aged men who work surveyed, 40 to 59 years old, is residing, Chung-Buk and Chung-Nam province, who understand the purpose of this study and agree to participate in this study. This study data is analyzed by using frequency, percentage, standard deviation, t-test, 𝑥² test and Logistic regression analysis. The study show that the exercise self-efficacy(𝛽=.965, p=.003) and the perceived health status(𝛽=.805, p=.025) among middle aged men who work have an effect on the stages of change of exercise meaningfully. That is, the exercise self-efficacy of middle aged men who work who have exercise behavior is 2.6 times higher than middle aged men at work who don't have exercise behavior, and the perceived health status is 2.2 times higher. This study suggests that the development of better exercise practice for middle aged men who work should be aimed at promoting exercise self-efficacy and perceived health status, Based on this, it is necessary to find ways to operate exercise programs at the workplace and community level.

As SPA brands are growing in Korean apparel markets, they are extending their well-established brands into new markets (i.e., SPA brand extensions). To investigate psychological mechanism underlying SPA brand extensions, this study conceptually proposed such consumer information processing of SPA brand extensions as (1) perception of similarity between SPA brand extensions and their original brands and (2) evaluations on the SPA brand extensions (i.e., attitude and purchase intent). For hypothetical SPA brand extensions (high, moderate and low similarity conditions), perceived similarity was measured by using a eye-tracker and evaluations were assessed by using a self-reported questionnaire. The results reveal that the amount of external information searching for SPA brand extensions was larger in the following order: moderate, low and high similarity conditions. The depth of SPA brand information processing was also deeper in the same order. Evaluations on SPA brand extensions were higher in high and moderate similarity conditions than in low similarity condition. The findings suggest that the evaluations are affected by perceived similarity and the amount of cognitive efforts in processing SPA brand extensions.

Using technology acceptance model, this study investigates the factors affecting N-screen service adoption. We collected 435 available answers from potential users through systematic online survey. Results show that self-efficacy and perceived interactivity factors had positive effects on perceived ease of use. In addition, service variety, perceived interactivity, perceived ease of use factors had positive effects on perceived usefulness. Yet social effect factor had negative effect on perceived usefulness. On the other hand, perceived ease of use and perceived usefulness had positive effect on the intention of use. In conclusion, to improve the intention to use N-screen service, it is necessary to make users convinced that N-screen service can give customized contents and interactive information regardless of time and place.

This study examined the physical self-concept and self-efficacy of undergraduates. Using the convenience sampling method of non-provability sampling, a total of 377 undergraduates from North Kyongsang Province G city were selected. Of the 377 completed questionnairescollected, a total of 354 surveys with structural equation modeling were analyzed using theSPSS 22.0 statistics program. The self-esteem, endurance, health, and flexibility factors have positive effects on improvingthe self-control efficacy factor of self-efficacy in the order of physical self-concept factors. On the other hand,the higher university students perceive that among the physical self-concepts, the physical activity factor had more negative effects on the self-regulated efficacy. The self-esteem, health, and muscle strength have positive effects on improvingthe confidence factor of self-efficacy in the order of physical self-concept factors. The more perceptive endurance than the appearance, sports competence, body fat, health, self-esteem, flexibility, muscle strength of physical self-concept, and the more influence on self-efficacy. Overall, the higher the perception of physical activity factors among the physical self-concept factors, the more negative effects on the task difficult preference.
