The purpose of this study was to analyze the relationship between organizational commitment, organizational loyalty, and working satisfaction of 162 teachers in daycare centers in Gyung-gi province. Three questionnaires about the organizational commitment which Allen and Mayer(1990) developed and Son Sobin(2002) revised, organizational loyalty behavior which Jo Bumsang(2004) revised, and working satisfaction which Kim Sunja(2005) developed, and the researcher revised were used for this study. For this study, the data was analyzed using descriptive statistics, independent t-test, and Pearson correlation. The results were as follows: first, the early childhood teacher's organizational commitment was average, and there was a significant difference according to the teacher's academic background. Second, the early childhood teacher's organizational loyalty was also average, and there were significant differences according to the teacher's age and academic background. Third, the early childhood teacher's working satisfaction was below average level, and there was a significant difference according to the teacher's working hours. Last, the early childhood teacher's organizational commitment, organizational loyalty behavior, and working satisfaction showed the positive relationship. In conclusion, the government and the director of daycare centers should support for the teacher's psychological satisfaction because the early childhood teacher's psychological state is highly related to successful organization of daycare centers.

The purpose of this study is to investigate early childhood student teachers' practicum anxiety on the basis of the teacher's image and self-efficacy during their practicum. The participants of this study were 499 student teachers who were enrolled in the department of early childhood education in a college or a university and had completed the practicum in Daejeon metropolitan city or the Chungcheong area. The instruments for this study were the Teacher's Image Scale, Practicum Anxiety Scale, Self-efficacy Scale, and a questionnaire for socio-demographic variables. The collected data were analyzed by using a t -test, F test, Pearson's partial correlation, and multiple regression with SPSS software (version 20.0). The results were as follows: First, the student teachers expressed higher practicum anxiety in a provincial area than in metropolitan city, and their self-efficacy was higher in public kindergarten than in private kindergarten. Further, the highest level of the teacher's image was obtained in the case of student teachers who enrolled in a 2- or 3-year college program and completed the practicum in the metropolitan city. Second, there was a significant negative correlation between the sum of student teachers' practicum anxiety and their professional skills of teacher's image as well as significant correlations between the sum of student teachers' practicum anxiety and their self-efficacy, except self-control efficacy. Finally, the student teachers' practicum anxiety was found to be 17.5%-24.4% and was explained the most by the confidence of self-efficacy.

Mathematical modeling activities are gaining popularity in K-12 mathematics education curricula worldwide. These activities serve dual purposes by aiding students in making sense of real-world situations intertwined with social justice while acquiring mathematical knowledge. Despite efforts to prepare teacher candidates for instructing in mathematical modeling within a single country, little attention has been given to teacher candidates' approaches to mathematical modeling on a social justice issue from different countries. This article employs an in-depth, small-scale comparative study to examine the approaches of U.S. and Korean teacher candidates in solving a justice-oriented mathematics task. Our findings reveal that, although both U.S. and Korean teacher candidates identified certain variables as key when constructing a mathematical model, Korean teacher candidates formulated a more nuanced model than U.S. candidates by considering diverse variables. However, U.S. teacher candidates exhibited a heightened engagement in linking the task to social justice issues, whereas Korean teacher candidates barely perceived real-world problems in relation to social justice concerns. This study serves as a valuable tool to inform the roles and limitations of teacher education programs, shaped within specific educational contexts.

Quality control of science teachers seems to be one of the most important tasks to improve the quality of science education in Korea. The purposes of this study, as a survey, were to identify characteristics of good science teachers and to make an outline of preservice teacher education curriculum for cultivating the characteristics from inserivce secondary science teachers. A questionnaire was developed for this study and distributed to 176 inservice teachers. It had three parts: 1) characteristics of good science teachers, 2) weights of preservice curriclum areas, and 3) weights of college courses. The means and standard deviations of teachers' responses were calculated. To test the differences between teacher variables, t-tests were executed. The inservice teachers perceived that the junior-high school teacher's characteristics should be different from the senior-high school teacher's. Characteristics, such as enthusiasm toward teaching or students, subject knowledge, content selection and organizing skill, teaching techniques, and scientific worldview were ranked within top five of good science teacher's chracteristics. The teachers' perception about preservice curriculum were as follows: 1) present weight of liberal arts area should be reduced: 2) weight of content area for junior-high school teachers should be different from that for senior-high school teachers: 3) present weight of pedagogy area should be increased: 4) present weight of science education area should be increased: and 5) many courses in pedagogy and sciencd education areas need to be changed, Based on the data and disussion, a conceptual model for preservice teacher education curriculum was proposed.

The ionic association constants (K) of 2, N-dimethyl pyridinium iodide (2NDMPI) in 95 volume percentage ethanol-water mixture were determined by a modified UV and conductance method at $20^{\circ}C{\sim}50^{\circ}C$ under 1 to 2000 bars. The K values increase with increasing pressure and decrease with temperature. The total partial molar volume change (${\Delta}V$) has relatively small negative value and the absolute ${\Delta}V$ value decrease with increasing pressure and temperature. The ion size (a) and solvation number (n) of 2NDMPI were about 5 $\AA$ and changed from 1 to 3 with decreasing temperature. Other thermodynamic parameters such as enthalpy (${\Delta}H^{\circ}$) and entropy (${\Delta}S^{\circ}$) for the equilibrium of the 2NDMPI were evaluated. From all the parameters mentioned above, we came to conclusion that the electrostriction effect of 2NDMPI in the ethanol-water mixture is enhanced with increasing pressure and decreasing temperature.

The authors examined a college mathematics professor's change process in teaching practice by analyzing the teacher's reflective journal. Her change engaged cooperative learning method in a college Algebra course and was geared toward the reform-oriented methods. The change processes were revealed as a bumpy road that was full of struggles and challenges to both the teacher and students. The analysis also showed that a reflective journey needed a proper means and support system from a teacher's environment such as institution. This research clearly showed that brining a genuine change in teaching practice toward a broad educational goal was a combined effort among the participants of education.
