The purpose of this study was to investigate the structural relationships school-aged children and related variables. For this study, the respondents were 704 children in elementary schools in the areas of Gyeongsan-Si and Daegu-Si. The questionnaires and psychological tests used in this study surveyed the following concepts: suicide ideation, social support, self-esteem and the scale of depression. The collected data were analyzed with AMOS 19.0, a statistical program for structural equation modeling, to estimate the hypothesized structural equation model. The results were as follows: First, self-esteem, - and depression as perceived by children were found to affect their suicide ideation directly. Second, parental support and teacher support as perceived by children were found to affect children's depression directly. Third, parental support, teacher support, and the support of friend's as perceived by children were found to affect-children's self-esteem directly. Last, parental support and, teacher's support did not show direct effect on children's suicide ideation, though these factors had an indirect effect on suicide ideation through the children's self-esteem and depression. Finally, teacher's support did not direct effectly children's suicide ideation, whereas it had an having indirect effect on suicide ideation through the children's self-esteem.

The theoretical rationale and basic materials for the improvement of the recognition on home economics teachers are suggested in this study through the close examination of the teacher’s recognition and its related variables. For this study, review of literature and questionnaire survey were performed. As the results, the following may be suggested. 1. There teachers more experienced and non-majored the home economics or those who finished professional course should be reeducated adequately for new direction of home economics education in secondary school and new curriculum. 2. The development of qualification for home economics teacher and the educational system and program for training preliminary should be try to find a solution to improve the new and positive recognition of home economics education in secondary school. 3. The institutional and environmental conditions, such as pay and welfare facilities, should be improved to satisfy home economics teacher with new view of home economics education in secondary school with their duties. 4. The systematic and concrete teaching programs for contents of improving new recognition of home economics education in secondary school, and for promoting positive self-recognition as home economics teacher, and for training the abilities of developing teaching materials and guiding practical techniques should be developed.

This study is to verify relative influence of individual, parent, peer, teacher-related variables as protective factors and risk factors of academic hatred. Surveys were conducted with 1,015 (women, 57.3%) high school third grade students across eight schools where are located in Seoul, Incheon, and Geyonggi province. Correlation analysis and hierarchical multiple regression analysis were performed. The findings are summarized as follows. Teacher's academic pressure did not have significant correlation with student's basic psychological needs, teacher's autonomy support, teacher's support, and peer support whereas other variables showed significant correlation each others. The hierarchical multiple regression analysis indicated that student's individual competence and autonomy, parent's academic support, and teacher's emotional support work as protective factors and that parent's academic pressure functions as a risk factor. The effects of peer support disappeared when teacher-related factors were included. In addition, the effects of teacher's autonomy support disappeared, while the effects of teacher's support strengthened when learner's basic psychological needs were input. This study is meaningful in that it clarified academic hatred which had not been studied in other research and that it provided theoretical foundation for subsequent studies on academic hatred by examining relative influence of related variables. Lastly, it presented its limitation, implications on intervening strategies in school counseling, and suggestions for later studies.

The purpose of this study was to investigate VHI, V-RQOL, and vocal characteristics of a teacher and singer. 56 subjects were participated in this study (20 subjects are a teacher with vocal nodule, 20 subjects are a singer with vocal nodule, and 16 subjects are normal speakers). All subjects completed the VHI, V-RQOL, and vocal characteristics were measured using CSL 4500(Kay Pentax. USA). 21 subjects completed the VHI, V-RQOL, and vocal evaluation using CSL 4500 twice to assess test-retest reliability. A statistical analysis was performed using the Statistical Package for Social Sciences 18.0 (SPSS Inc, Chicago, IL). The VHI and V-RQOL showed that the teacher and singer group were significantly higher than those of the control group in functional, physical and emotional aspects(p<0.05). the acoustic analysis using CSL 4500 showed the teacher and singer group were significantly higher than those of the the control group in fundamental frequency related variables, fundamental perturbation related variables, amplitude perturbation related variables, noise related variable, and tremor related variables(p<0.05). Conclusionally, the teacher and singer group recognized their voice problems as a serious physico-functional aspects.

The purpose of this study purpose was to analyze the structural model of variables such as experiences and personal- and professional- beliefs of cultural diversity, and the culturally responsive teaching efficacy of early childhood preservice teachers including identifying the beliefs as mediating variables. Another purpose was finding the different structural relations among the research variables according to the stages of a teacher education program. The participants were 273 students who enrolled in K grade teacher education programs in the southwest areas of the U.S. The research variables were measured with the items used by Schroeder (2008), Pohan and Aguilar (2001), and Siwatu (2007). The structural equation model analysis showed that the direct effects were found between the paths from the cultural diversity experiences and personal beliefs to the culturally responsive teaching efficacy, from the experiences to personal beliefs, from the personal to professional beliefs. The personal beliefs were identified as a mediator of the path from the experiences to professional beliefs. By multi-group analysis, the path from professional beliefs to the culturally teaching efficacy showed a meaningful difference between the initial and final stage groups of a teacher education program. Suggestions for future research and early childhood teacher education programs were presented based on the results.

This dissertation aims to analyze various safety accidents taking place during physical education class according to physical education teacher's value orientation, to identify teacher's value orientation that can minimize safety accidents, and to provide basic materials for safe and smooth class management. For this purpose, data have been collected from 261 physical education teachers at some middle and high schools in G City in Kyung-Ki Province and Busan Metropolitan City. The materials were treated as follows: The variables on demographic characteristics of physical education teachers are determined by t-test ; The analysis of one-way ANOVA and relationship between value orientation and safety accident prevention activities was conducted through Pearson's linear correlation analysis and multiple regression; The analysis of the relationship between value orientation and actual conditions of safety accidents was conducted through logistic regression. First, there is almost no awareness difference of physical education teachers' value orientation according to demographical variables. The value orientation physical education teachers consider to be the most important is, however, mainly 'mastery of disciplinary lesson.' There is a statistically significant difference in safety accident prevention activities according to demographical variables. Teachers' focuses in class contents showed a significant difference according to teaching experience and working area, while the dependency on facility has a significant difference according to teaching experience and school type. Second, there is no correlation between physical education teacher's value orientation and safety accident prevention activities because there is virtually no statistically significant difference between them. It means that safety accident prevention activities are not related with on which teachers place emphasis among mastery of disciplinary lesson, social reconstruction, self-realization, ecological integration and value orientation on learning process. Third, the analysis of safety accident prevention activities according to physical education teachers' value orientation revealed that the lower value orientation in social reconstruction is, the more safety accidents teachers experience. It is also found that crashes among students, ball games and leg injuries are inter-related with social reconstruction in value orientation, over-motivation and unskilled motor function ; athletic sports with value orientation on learning process and safety prevention training ; unskilled motor functions with value orientation in ecological integration and disobedience to teacher's directions ; winter accidents with mastery of disciplinary lesson in value orientation. In conclusion, the research indicates that physical education teacher's value orientation according to demographical variables didn't show any significant difference, while one according to safety accident prevention activities showed significant difference. Besides, physical education teachers' value orientation is not related to safety accident prevention activities, but the relationship between value orientation and actual conditions of safety accidents showed correlations according to each variable. Especially, teachers with lower value orientation in social reconstruction experienced more safety accidents. Therefore, physical education teachers can manage physical education class more safely with more emphasis on value orientation in social reconstruction.

The purpose of this study is to determine the level of key competencies and teacher efficacy of pre-service industrial teachers as related to their personal backgrounds, and to analyze the correlation between personal variables, key competencies and teaching efficacy. This will be provided as basic resources for pre-service teacher training program to improve the understanding of key competencies and teaching efficacy of pre-service industrial teachers. The results of this study are as follows. First, the teacher efficacy of pre-service industrial teachers was found to be above average (M=3.0), and teaching efficacy (M=3.41) was found to be a bit higher than personal teacher efficacy (M=3.28). Upon analyzing the significant differences of teacher efficacy resulting from background variables, it was found that gender and major had no difference while the effect of school year on teaching efficacy of teacher efficacy showed statistically significant differences. Second, the lower regions of key competencies of pre-service industrial teachers all were above the average 3.0. Gender and school year were exhibited no significant difference, and only the global competence of key competencies showed significant difference. Third, it was found that the gender and major of pre-service industrial teachers had no correlation with teacher efficacy and key competencies. On the other hand, school year variable showed significant positive correlation with teacher efficacy (r=.274) and key competencies (r=.168). Lastly, it was found that key competencies and teacher efficacy had positive correlation of r=.475.

In this paper we use iterative dynamic programming in the discrete case to solve a wide range of the nonlinear equations systems. First, by defining an error function, we transform the problem to an optimal control problem in discrete case. In using iterative dynamic programming to solve optimal control problems up to now, we have broken up the problem into a number of stages and assumed that the performance index could always be expressed explicitly in terms of the state variables at the last stage. This provided a scheme where we could proceed backwards in a systematic way, carrying out optimization at each stage. Suppose that the performance index can not be expressed in terms of the variables at the last stage only. In other words, suppose the performance index is also a function of controls and variables at the other stages. Then we have a nonseparable optimal control problem. Furthermore, we obtain the path from the initial point up to the approximate solution.

This study examined the effect of infant teacher's sensitivity, efficacy and interaction on the social and emotional development of infants. The participants of this study were 169 infants and their teachers in daycare centers located in Seoul and Gyeonggi-do. The instruments were collected through teachers' responses. Data were analyzed through the variance analysis using PASW 18.0 to verify the infant teachers' susceptibility, efficacy, and infant-teacher interaction based on infant teachers' background variables; to find out the relationship between the variables, Pearson correlation analysis was performed, and to find out the relative influence of variables on the infants' social and emotional development, stepwise multiple regression analysis was performed. Results were as follows. Firstly, Among the background variables of the teachers, their career as infant teachers displayed differences in the infants' social and emotional development, and the susceptibility, efficacy, and infant-teacher interactions displayed partial differences based on the teaching career, career as infant teachers, age, daycare center type, and the academic background of the teachers. Secondly, there were positive relationships between infant teacher's sensitivity, efficacy and interaction and infants' social and emotional development. Thirdly, infant teachers' sensitivity, efficacy and infant-teacher interaction had an influence on infants' social and emotional development at the same time. Especially, sensitivity and interaction were powerful and influential variables and their explained variance was 53%. These results suggested that teachers' efforts must be made to interact positively with infants and to increase their sensitivity level to respond to infants in order to increase infants' social and emotional development.

This study examined the mediating effects of self-esteem on the teacher-young child relationship and self-regulation ability of young children. A survey was conducted on a random sample of 252 young children aged 3-5 years attending a nursery in Gwang-ju, Korea. Based on the data, Person's correlations between variables were analyzed, and hierarchical regression analyses were conducted to identify the direct and indirect effects of the teacher-young child relationship and self-esteem on the self-regulation ability of the young children. First, there were positive correlations among the teacher-young child relationship (intimacy) and self-esteem as well as self-regulation ability. There were negative correlations among the teacher-young child relationship (conflict, dependence) and self-esteem as well as self-regulation ability. Second, self-esteem partially mediated the correlation between the teacher-young child relationship and self-regulation ability. The results suggest that self-esteem may affect the self-regulation ability of young children as a mediating response to the teacher-young child relationship.
