In current computer education, we have inclined to emphasize information literacy for k-12 students. On the other hand, in spite that teachers are core variable in school education system, we have neglected teacher's education of information and communication technology. In addition, we haven't made a effort to expand preservice teacher's ability to utilize information and communication technology in the teacher's college and the college of education. With these recognitions, we made a diagnosis of problems by analysis of current condition of curriculum of the teacher's college and the college of education and explored the vision of ICT utilization education in k-12 computer education in this study. In addition, we suggested educational objectives and contents based on national requiring standards for ICT in teacher preparation, required ICT capability of preservice teachers for kind of teacher's task and the direction of computer education.

This paper is aimed to improve the current curriculum in the Korean elementary school’s practical course, which covers both industrial fields and Home Economics. Specially inveotigated here are teacher’s attitude toward the practical course and the degree of difficulty in teaching each content of the practical course in the 4th and 5th grade in the elementary school in term’s of teacher’s sex and localing. Since two heterogeneous subjects, industrial fie인 and Home Economics, are integrated into one subject named the practical course, the teaching of the practical course is not specialized. Besides, the teaching is implemented inefficiently, owing to the teacher’s misunderstanding of the practical course. In this respect, as a way of maximizing the effectiveness of practical course in elementary school, the authors suggest some proposals. (1) The curriculum of practical course should be divided into two course, industrial fields and Home Economics (2) All students should be completed Home Economics as a required course (3) A system of full-time teacher for Home Economics subject should be introduced. Concurrently, the curriculum of the practical course in Teacher’s College be modified.

The purpose of this study is to investigate the relationship between teacher's self-efficacy and teacher's leadership in kindergartens and child care centers. The subjects are 215 teachers employed in kindergartens or child care centers in Chungnam & Daejeon Metropolitan City. Questionnaires, which required self-reporting by teachers, are used to investigate teacher's self-efficacy and teacher's leadership. The data are analyzed by frequency, percent, Pearson's correlation and stepwise regression. The results of this study are as follow. First, teacher's self-efficacy is positively associated with teacher's leadership. Second, teacher's self-efficacy affect teacher's leadership.

This study compared influential factors on adolescent's (10-16 years of age) self-concept in Korean-chinese and Korean cultures. The influence of parenting, peer relationship, and teacher's support on the development of children's and adolescent's self-concept was assessed with Korean-Chinese and Korean elementary, middle, and high school students. The subjects were 210 Korean-Chinese children and 300 Korean-Chinese adolescent from Shenyang, China, and 280 Korean children and 400 Korean adolescents from Seoul and Ulsan, Korea. Data were analyzed by t-test, factor analysis, and multiple regression. The results revealed differential influences of factors between the two cultures. Korean-Chinese children's self-concepts were influenced by teacher's support and parenting, while Korean children's self-concepts were significantly influenced tv their peer relationships and teacher's support. Korean-Chinese adolescent's! self-concepts were influenced tv teacher's support and parenting, while Korean adolescent's self-concepts were influenced by parenting and teacher's support.

The purpose of this study was to investigate the characteristics of a teacher's questions in each context of musical activity by analyzing those questions in kindergarten music activity qualitatively. The participant in research was a teacher in charge of the class of children aged 7. Analysis was carried out on the data collected for 3 months through participation observance note, recording material, interview material and weekly plan. As a result, the teacher's questions were leaned upon the convergent questions to confirm the reflection of information and the understanding of function in singing and performing activity. On the other hand, the teacher's questions were leaned upon the diffusive questions for the thought of integration of information in composition activity and upon the diffusive questions for representing feeling or image with no relation to musical meaning in appreciation activity. However, the teacher's questions for control were conducted together with one of the questions, the question mentioned ahead. The tacit control question in singing and performing activity and the explicit control question in composition activity were conducted together, and in appreciation activity, the simple questions to lead the class, though not with the purpose to control attention, was conducted together.

The aim of study was to identify factors influencing the self-confidence in the teacher's role on adolescent suicide. The cross-sectional descriptive study design was used. Participants were 318 teachers from elementary, middle, and high school in D city. Data were collected using questionnaires which included general characteristics, attitude toward adolescent suicide, knowledge about guideline for adolescent suicide prevention, and self-confidence in the teacher's role on adolescent suicide. Collected data was analyzed using descriptive statistics, t-test, Pearson correlation coefficient, and multiple regression with SPSS 21.0 program. The results of the regression analysis revealed that experience of suicide education, attitude, and knowledge about adolescent suicide were the significant factors affecting the self-confidence in teacher's role for adolescent suicide. The predictor variables explained 22.5% of variance regarding self-confidence in teacher's role for adolescent suicide. Findings indicate the factors should be used in developing effective intervention for enhancement of self-confidence in teacher's role on adolescent suicide.

The purpose of this study is to explore degree of childcare teacher's teacher efficacy and the factors influencing of self-esteem and job stress on teacher efficacy of those surveyed. A total of 280 childcare teacher in G do were surveyed. All of this data is analyzed by using t-test, ANOVA, Pearson's correlation coefficients, multiple regression analysis with SPSS WIN/18.0. Teacher Efficacy according to general characteristics of those surveyed revealed significant difference in age, work experience, position, class age, and child parenting experience. Regression analysis showed 11.7% of variance in childcare teacher's teacher efficacy can by experience of dating with self-esteem and job stress. The fallow-up survey about various factors influencing childcare teacher's teacher efficacy is needed and teacher efficacy increasing mediation way are required.

The association constants (K) of 3,5,N-trimethyl pyridinium iodide in 95 volume percent ethanol-water mixed solvent were determined by a modified UV and conductance method at $25^{\circ},\;30{\circ},\;40{\circ}\;and\;50{\circ}C$ over the pressure range 1 to 2000 bars. The association process is enhanced with increasing pressure and decreasing temperature. From K values, we obtained the total partial molar volume change (${\Delta}V$) and some thermodynamic parameters. The electrostriction volume (${\Delta}V_{el}$) and intrinsic volume (${\Delta}V_{in}$) were also evaluated. The values of ${\Delta}V,\;{\Delta}V_{el},\;{\Delta}V_{in}$ are negative, negative and positive, respectively, and the absolute values of all these three decrease with increasing pressure and temperature. The ion-pair size (a) were varied 3 to 6 ${\AA}$, with pressure and temperature. The solvation number (n) decreased from 2 to 0.5 with increasing temperature.

The dissociation constants(K) of m-chloroanilinium ion in water-ethanol mixture, where the volume percentage of water is 89.5%, were evaluated by UV-spectroscopic method at $20{\sim}50^{\circ}C$, up to 1500 bars with changing ionic strength from 0.04 to 0.10 mol $kg^{-1}$ by use of acetate buffer. K values enhance with increasing ionic strength and temperature, but decrease with elevating pressure. From K values, we obtained the partial molar volume change and some other thermodynamic parameters. From the values of enthalpy, entropy and isoequilibrium temperature (649 K), we concluded that the dissociation of m-chloroanilinium ion mentioned above is controlled by enthalpy.
