In 1966, Iseki [4] introduced the notion of BCI-algebras which is a generalization of BCK-algebras. The ideal theory plays an important role in studying BCK/BCI-algebras. In this paper we study decompositions of ideals in BCI-algebras, and give a characterization of closed ideals. Also we define ignorable ideals in BCI-algebras, and investigates its properties.(omitted)

This study was to investigate the moderating effects of the childcare teacher‘s egoresilience on the relationship between their job satisfaction and burnout. The participants were 336 childcare teachers from Chungnam-do and Daejeon Metropolitan City. The research instruments were the Job Satisfaction Scale modified from Bently and Remple 1970), the Ego-resilience Scale from Park(1996) with CPI and CAQ correction, and Maslach Burnout Inventory from Maslash and Jackson(1981). SPSS PC program(17.0) was used for productive correlation, stepwise multiple regression and reliability by Cronbach's as data analysis. The results were as follows. Firstly, the childcare teacher’s job satisfaction and ego-resilience level were above average (M=3.37, 3.58 each), while their burnout level was below average(M=2.57). Secondly, there was a negative correlation between their job satisfaction and burnout(r=-.51), while a positive correlation was between their job satisfaction and ego-resilience(r=.34). Thirdly, the burnout and ego-resilience against job satisfaction explained 28.1%. The optimistic attitude of the childcare teacher‘s ego- resilience was shown to moderate the effects on the relationship between their burnout and job satisfaction.

In this study, we analyzed career paths and college life plans of department of chemistry education students in teacher's college examined by their roadmaps. We let students make their roadmaps and analyzed them using the PASW 18 program. There were significant differences on gender in their career paths, learning English, traveling and volunteer activity. Female students for passing the MEET(Medical Education Eligibility Test) or DEET(Dental Education Eligibility Test) were more interested in learning English and traveling than male students. In addition, female students were more interested in volunteer activity. And the lower year students, the more interested in medical paths, learning English, traveling, getting good grades, exchange student program and scholarship. On the other hand the higher year students, the more interested in group study or E-learning. Then significant differences were in learning English, traveling and getting good grades by students's career paths. Students who wish to pass the MEET or DEET were more interested in learning English and getting good grades. Those two factors were essential in passing the MEET or DEET. Students who did not specified their career paths had more traveling plans than other students for setting their directions of careers. These results show that freshman and female students don't recognize the identity of teacher's college correctly. Because of reduction in the number of teacher recruitment according to decrease of students by birth rate drop, students in teacher's college are expected to continue like this trend that students look for other paths. Therefore, it is required career counseling and guidance for students who give priority practical path choices and college life plans over original characteristics of teacher's college. And it should be reconsidered the direction of chemistry education prepared the identity of teacher's college reflected in this actuality.

After the integration of early childhood education and child care, young children school's teacher qualification conversion training for in-service teachers is necessary. In this study, the subjects and operation modules of teacher qualification training were examined. As a result of the study, it was found that kindergarten teachers without child care teacher qualifications needed 4 subjects and 12 credits, and teachers with only child care teacher qualifications needed 14 subjects and 30 credits. As qualification training institutions, the Department of Early Childhood Education at a 4-year University, the Department of Early Childhood Education at a junior College, and the Korea National Open University were proposed. In the case of kindergarten teachers who do not have a child care teacher, it was found that they could change their qualifications through job training.

This study examined the effect of preservice child care teacher's competency on career stress and the effect of career aspration as a mediayor in the relationship between teacher's competency and career stress. The survey based on self report questionnaires was administered to a total of 200 students in child education and care college in Gyeonggido areas. The results of this were as follow: First, the result which examined the correlationship between major variables has found to be the significant correlationship of preservice child care teacher's competency, career stress and career aspiration. Preservice child care teacher's competency and career aspiration have found to have significant positive correlation but career stress and Child care and education teacher's competency and career aspiration have found to have the negative correlationship. Second, the result which examined the mediated effect of career aspiration in the relationship between teacher's competency and career stress has found that career aspiration has the complete mediated effects. Consequently, the mediating effects of career aspiration were confirmed. Based on the above results in the study meanings. limitations and proposals for next studies in the study were discussed.

In this study, I examined the direct or indirect paths among the intra-personal factors as well as extra-personal factors affecting on children's peer competence. Subjects were 514 5-year-old children, their mothers, teachers. The teachers rated each children using Peer Competence Scale (Park, 2001) and completed emotion regulation and Student-Teacher Relationship Scale. The mothers responded to a questionnaire, including Parental Involvement Checklist (Cohen, 1989), parenting behaviors, and Children's Temperament. The data were used for path analysis with Amos 6.0 program. Results of this study were : (1) Children's temperament have an influence on children's peer competence through children's emotion regulation via mothers' parenting behaviors. (2) Children's temperament have an influence on children's peer competence through teacher-child relationship. (3) Mothers' parenting behaviors have an influence on children's peer Competence through mothers' management strategies of peer relations.

In this study, we investigated pre-service secondary chemistry teachers' use of teacher's guide in planning lessons. Eleven pre-service teachers at a college of education in Seoul participated in this study. Textbooks and teacher's guide books including various teaching materials were provided. Pre-service teachers used teacher's guide while they planned two lessons, which were a lecture and an instruction using science teaching model. A semi-structured interview was conducted. All of the teaching-learning materials and interviews were analyzed. The analyses of the results revealed that most pre-service teachers followed each lesson presented in teacher's guide, but they did not consider the structure of the whole unit and science curriculum. There were some cases that the exemplary lesson planning in teacher's guide helped them to select science teaching model. They modified the questions of textbook activity in planning their lecture. On the other hand, they modified the activity to fit each stage of the model in planning their instruction using science teaching models. Most pre-service teachers constructed their own worksheets by applying the materials of the teacher's guide. They recognized the components of assessment by considering exemplary lesson planning from the teacher's guide, and created questions by modifying the content of textbooks and teacher's guide books including various teaching materials. However, the questions which they made were limited in context of knowledge. They evaluated that introductory questions were not of interest to students, and modified or added new materials. Educational implications of these findings are discussed.
