Purpose: This study investigated differences in the relationships of factors including emotional problems, self-perception, parental behavior, and peer attachment with smartphone dependency (SD) among middle school, high school, and college students in South Korea. Methods: This study used data from a nationwide sample of 1,882 middle school, 1,821 high school, and 1,346 college students who owned smartphones. Descriptive statistics and multiple regression analysis were conducted to investigate the predictors of SD based on school level. Results: SD scores significantly differed across school levels. Female gender, more aggressive behavior, less ego-identity, and less monitoring parental behavior were linked to higher SD at all school levels. Less self-esteem and intrusive parental behavior were linked to SD in middle school students. In high school students, additional factors related to higher levels of SD were resilience, intrusive / inconsistent parental behavior, peer trust and alienation, and depression. Additionally, resilience, over-expectant parental behavior, and peer trust were linked to higher SD in college students. Conclusion: This study provides insights into SD and predictors of SD among middle school, high school, and college students. Based on these findings, SD prevention programs should be developed according to the developmental stages of adolescents and young adults.

This study aims to examine the relationship between teachers' parcitipation levels in the decision making process and the organizational effectiveness in the middle schools. To achieve this objectives, 559 teachers of 18 middle schools in Busan were involved through a questionaire. The results are as follows: First, teachers consider their participation in decision-making to be low. Second, teachers view the effectiveness of school systems higher than average. Third, the correlation between teachers' participation and the system effectiveness (including job satisfaction, organization adaptability and job achievement) was positively high. When teachers' participation levels were divided into 3 groups - low, middle, and high-, the system effectiveness appeared highest with the high- level participation group. These results suggest the need for teacher participation in decision making to enhance the effectiveness of school systems.

For this purpose, I have found out explored the differences between depression and aggression of in middle school students in accordance with sex and grade, and also found a relationship between DAS response characteristics, and the level of depression and aggression. The subjects of this study were 600 middle school students in Pusan and Kyungnam, and the tools used in this study were Silver's Draw-a-Story and Beck's depression scale and aggression scale. The results were analyzed two-way ANOVA analysis, Duncan test, correlation analysis and crosstab analysis. The results of this study are as follows. The depression level of the 9th grade students was higher than that of 7th grade students. And the aggression level of males was higher than in females, and higher in 8th graders than in 7th graders. The emotion content scores and the self-image scores were related to depression and aggression. So when the levels of depression and aggression were high, the emotional response of DAS and the self-image response were negative. Through this study, it is suggested that DAS has the power of discrimination as a tool measuring depression state and that DAS is meaningful because it showed it can be used as a tool for estimating the level of depression state of school students in schools.

The purpose of this study is that the Van Hiele theory can be applied to even vocational high school students. Through the comparison of Van Hiele level distribution of middle school students and high school students, it is that the aims of this study is to study the geomatric level of vocational high school students and to analize them, even so it can be to find for them the effective method of Geomatric education The subject of study is three kinds of vocational high school - commercial high school, industrial high school, fisheries high school - boys (240), girls (120) in Boryeong city, Chungchong Nam Do. We referred to Kim Mi-cheong′ thesis(1994) and Cheong Yean-sok′s thesis(1992) and compared my result with them. The method and the process of the study were based on the th method of CDASSG project. And we used Van Hiele Level Test as an instrument of measurement. We got the following conclusion as the result of the study 1. The 86％ of the subject of the study was applied to the theory of Van Hiele - "Any students can reach level n just through level n-1." Even so the propriety of the theory proved to be from this study again. 2. The 88% of the subject of the study is applicable to below level 2. So if the proof is introduced to them in the class, it was very difficult for them to understand it. 3. The geometric level of vocational high school students is the same as the second grade of middle school. But we think to be desirable that a basic concept puts first in importance through recomposed teaching materials, because 68% of the students is seldom changed at level 1.

The purpose of this study was to identify the preferable motivation types in science-learning and to find out the relationship between these types and scientific achievement of students in the secondary school. The subjects of the study were the second grade 581 students sampled by random cluster sampling method in three middle schools and three high schools. Three motivation types in science learning were analyzed, and they were named to task-orientation, ego-orientation and work-avoidance. From our results, secondary school students preferred task-orientation and work-avoidance to ego-orientation. In the case of task-orientation, high school students, especially in male group, had much preferable tendency than that of middle school students (p<0.001). It is interpreted that, as the level of scientific content of texts or the cognitive level of students were higher, a preference for the motivation type was focused to the task-orientation, especially in male group. In the case of ego-orientation, the female group showed much preferable tendency than that of male group in middle school (p<0.05). However, the female group in high school students was not different from the other groups in this motivation type. In the case of work-avoidance, there were not only a significant difference between males and females in the middle school (p<0.001), but also difference between middle and high school students in female group (p<0.05). It showed that female group had much preferable tendency than that of male group, and this tendency was decreased to the higher grade students in secondary school. From the analysis of correlation between motivation types and scientific achievement, task-orientation and work-avoidance were correlated to the scientific achievement. Its results were interpreted that the scientific achievement could be accomplished by the external motivation stimulus as well as the scientific content of texts. The task-orientation were comparatively correlated to the intelligence quality. It means that the students having high intelligence quality showed much preferable for the task-orientation.

This study estimates the influence of organizational-level factors on work motivation and job performance of middle managers of small and medium enterprises (SMEs) in Vietnam. A 5-point-Likert-scale structural questionnaire consisting of 36 observation variables was used to survey middle managers of Vietnamese SMEs. 425 out of 500 responses collected were valid for multivariate data analysis. The results of confirmatory factor analysis and structural equation modeling reveal three main findings. First, philosophy and policy, compensation and benefits, goal system, and leadership have positively significant impacts on the work motivation of middle managers under investigation. Second, there is a significantly positive influence of work motivation on job performance. However, there is no indication that growth opportunities, work environment, evaluation system have significant impacts on the work motivation of respondents. Based on the findings, the study suggests four recommendations for Vietnamese SMEs to improve motivation and job performance of middle managers, which are (1) ensuring the clarity and soundness of the organizational policies and philosophies, especially human resources policy that boosts employees' work motivation; (2) building a comprehensive compensation and benefit system to attract and retain talented employees; (3) developing a clear and adequate goal system; (4) enhancing top-level managers' leadership abilities.
