This study investigated relationships between academic stress and mathematics learning motivation focusing on the mediating effect of academic motivation types. It also tested differential structural relationship among the variables in the high vs. low academic achievement level groups and the boys vs. girls of middle schools. The participants were 952 second graders from five middle schools. Student scores from the standardized tests that were developed to assess the students' academic stress, mathematics learning motivation, and three types of motivation (amotivation, controlled motivation, and autonomous motivation) were used in this study. The results demonstrate that there were significant differences in the relationship patterns of the research variables. Correlation analysis provided evidences that academic stress was negatively related with mathematics learning motivation and autonomous motivation but positively related with amotivation and controlled motivation. Also, mathematics learning motivation was negatively related with amotivation and controlled motivation but positively related with autonomous motivation. Structural equation modelling analysis provided the evidence that the full mediation model was a significant, in that the students' types of academic motivation mediated the effect of academic stress on mathematics learning motivation. Multiple group analysis revealed that there were group differences in the path coefficients of the structural model. But the academic stress showed negative influence on the mathematics learning motivation via amotivation and autonomous motivation in all groups.

The purpose of the study is to explore the relationship among learning motive, job creativity, major satisfaction and school satisfaction of enrolled students in 2 vocational schools in Seoul. Hypotheses based on the relevant literature are tested. Job creativity was found to be positively influenced by learning motives and autonomy. Intrinsic learning motive and autonomy affect student's major satisfaction, but extrinsic learning motive was found to have negative effects on major satisfaction as autonomy trait was irrelevant to school satisfaction. Vocational college programs offer mainly technical and on-the-job training unlike general colleges. Thus, students are psychologically sensitive to school programs and multidisciplinary approach is needed.

This study applied self-determination theory to investigate the relationships between volunteers' perception of supervisors' autonomy support, volunteering motivation, and persistence intentions among collegiate students. Collegiate volunteers(n=515) involved in volunteer activities completed measures of supervisors' autonomy support, 5 forms regulation, and persistence intentions. Bivariate correlations indicated that volunteer motivation demonstrated an ordered pattern of relationships, such that adjunct points along the regulatory continuum would be more positively associated with on another than distal points. Analyses using structural equation modeling revealed that supervisors' autonomy support was positively related to more autonomous motivation(intrinsic motivation and identified regulation), while was natively associated with amotivation. Amotivation was negatively related with persistence intentions, and more autonomous motivations(intrinsic and identified) predicted grater intentions to continue with volunteer activity for next 6 months. The findings are discussed in light of the self-determination theory.

The purpose of this study was to examine relations in autonomy support, self-determined motivation, and learning outcomes among college students. The subjects of this study were 231 college students in Jeonnam Province and Daejeon city, sampled by convenience sampling. The result of this study is as follows: First, perceived autonomy support had a significant direct positive effect on identified and intrinsic motivation. Also perceived autonomy support had a significant direct positive effect on learning outcomes and processes. Second, external had a significant positive effect on duty motivation and duty motivation had a direct positive effect on identified duty. In addition to identified motivation had a significant positive effect on intrinsic motivation, learning outcomes and processes. Third, intrinsic motivation had positively influenced on learning outcomes and processes. As the last of the findings, perceived autonomy support, duty motivation and identified motivation had significant effects on learning outcomes and processes. These results imply that perceived autonomy and self-determination motivation is important to enhance academic performance.

Academic procrastination has been a concern for educators. The purpose of this study is to investigate the relationship among task value, academic self-efficacy, autonomous motivation, self-regulated learning, and academic procrastination in e-learning courses. Based on the literature review, the path model was proposed and tested with 212 university students who registered in e-learning courses. The results showed that task value and academic self-efficacy positively influenced autonomous motivation and self-regulated learning, and autonomous motivation and self-regulated learning reduced the level of academic procrastination directly or indirectly. Implications and strategies to reduce procrastination were discussed based on the findings.

The purpose of this study is to understand student's reading motivation by laying out self-selected reading program and running it at school libraries. The self-selected reading program based on self-determination theory ensures the autonomy of book selection. The self-selected reading program in this study provided a number of scope and recommended book lists in order to ensure the autonomy of book selection and developed integrated reading and writing. After finishing this program, the author measured 6 domains of reading motivation with participated students who completed this course. As a result, it turned out that autonomous motive domains excessively surpassed heteronomous motive domains. Such autonomy of book selection, one of the key features from self-selected reading programs, is expected to help making the best use of school library collections by recommended book lists and stimulating stable and sustainable reading habits driven by self-motivation.

This paper proposes an autonomous decentralized frame synchronization system for Ad-hoc Inter-Vehicle Communication Network (IVCN). We have to consider the feature of Ad-hoc IVCN: "time variant" about the number and the location of vehicles and receive power in IVCN, frame timing, and fading. Proposed scheme is different from other decentralized synchronization systems that have association with a fixed base station, and from centralized Personal Communication Systems. This system includes an autonomous decentralized frame synchronization scheme for Ad-hoc IVCN, a high-speed algorithm, a protocol for a newly joining subscriber in IVCN, and a utilization of spread spectrum ranging for frame timing error of the system under highway conditions. Performance evaluation of proposed scheme is validated through simulation. It is shown that Ad-hoc IVCN can be carried out among one and surrounding vehicles in such environment.

The present study aims to evaluate the self-determined motivational features of smartphone addiction management apps. This study analyzed whether smartphone addiction management apps have features to support adolescent users' basic needs, that is, autonomy, competence, and relatedness. 26 apps were analyzed. Among them, 8 apps were parental management apps installed on a parent's phone and a child's phone, and 18 apps were self-management apps installed on a child's phone. According to a content analysis, only 3 of 26 apps addressed all three basic needs. Overall, the functions to support users' competence and relatedness were rarely found. Particularly, parental management apps had a high level of controlingness. The results suggest that the addiction management apps have limitations in stimulating adolescent users' self-determined motivation to manage their phone use.
