The notion of intuitionistic fuzzy semi-pre interior (semi-pre closure) is introduced, and several related properties are investigated. Characterizations of an intuitionistic fuzzy regular open set, an intuitionistic fuzzy semi-open set and an intuitionistic fuzzy ${\gamma}$-open set are provided. A method to make an intuitionistic fuzzy regular open set (resp. intuitionistic fuzzy regular closed set) is established. A relation between an intuitionistic fuzzy ${\gamma}$-open set and an intuitionistic fuzzy semi-preopen set is considered. A condition for an intuitionistic fuzzy set to be an intuitionistic fuzzy ${\gamma}$-open set is discussed.

현대 사회의 급격한 변화는 직업세계에 영향을 미치게 되었고, 이에 따라 진로 교육의 중요성이 그 어느 때보다 강조되고 있다. 체계적인 진로교육에 있어 학교에서의 진로교육이 중요하다는 논의가 지속되고 있음에도 불구하고, 학교 현장에서의 진로교육은 행사위주의 단발성 교육이 주를 이루고 있는 현실이다. 비록 많은 학교에서 「진로와 직업」 교과를 선택하여 운영하고 있기도 하지만, 학교 체제의 구조적인 한계로 인해 내실 있는 진로교육이 운영되기 힘들기 때문이다. 이에 대한 해결책으로 학교에서의 진로교육은 기존 교과와 교육과정 측면에서 연결되어 시행되어야 한다는 의견들이 최근 빈번하게 제기되고 있는 가운데, 교과통합에 의한 진로교육의 선진 외국 사례 분석은 향후 우리나라의 학교 진로교육에 의미 있는 시사점을 제시할 수 있을 것이다. 이에 이 연구는 교육과정 내에 진로교육을 통합시키려는 많은 노력이 정부 차원에서 이루어지고 있는 호주의 사례를 연구의 대상으로 하였다. 이 연구는 인터뷰와 문헌분석을 바탕으로 호주 연방정부 및 주정부 수준에서의 교과통합 진로교육 현황과 주정부별 정규교과 내 진로교육 내용을 분석하였다. NSW주의 건강 및 체육 교과에는 자신과 대인관계를 포함하여 진로교육 요소가 중점적으로 포함되어 있었고, SA주의 경우는 일의 세계에 대한 광범위한 이해를 범교과적으로 강조하고 있었으며, VIC주는 사회 및 환경교과에 진로교육 요소가 중점적으로 포함되어 있었고, NT주의 경우에는 핵심학습 교과의 내적학습자 단원에 진로교육과 관련된 내용요소들을 포함하고 있었다. 이러한 연구결과를 바탕으로 우리나라의 교과통합 진로교육에 주는 시사점이 도출되었다.

The purpose of this study is to analyze how high school students form and interpret the mental image in the process of solving regular polyhedron problems. For this purpose, a set of problems about the regular polyhedron's vertex is developed on the base of the regular polyhedron's duality and circulation. and applied to 2 students of the 12th graders in D high school. After 2 hours of teaching and learning and another 2 hours of mental image-analysis process, the following research findings are obtained. Fisrt, a student who recorded medium high-level grade in the national scholastic test can build the dynamic image or the patten image in the process of solving regular polyhedron's vertex problems by utilizing the 3D geometry program. However, the other student who recorded low-level grade can build the concrete-pictorial image. Second, pattern image or dynamic image can help students solve the regular polyhedron's vertex problems by proper transformation of informations and the mental images while the concrete-pictorial image does not help. Hence, it is recommended that the mathematics teachers should develop teaching and learning materials about the regular polyhedron's duality and circulation and also give students suitable questions to build the various mental images.

Objectives: The purposes of this study were to investigate the life satisfaction, obesity, depression, self esteem, body image of adolescents by their demographic characteristics, to analyze factors impacting on life satisfaction, and to provide basic data to intervention programs for bright and healthy development. Methods: The data in this study came from the Korea Youth Survey Data collected through questionnaires from 10,156 students. To investigate the causal relationship between each variable presented in the research model, descriptive statistics, t-test, ANOVA, Scheffe's test, correlation analysis, hierarchical regression analysis were carried out by using SPSS Ver. 18.0. Results: The most impacting factor on adolescents' life satisfaction were the self-esteem and depression, followed by the economic level, regular exercise, and regular eating. In conclusion, the strongest factors that influenced adolescents' life satisfaction were self-esteem and depression. Also we found that regular eating, regular exercise, and adequate sleep were the important causes of raising adolescents' life satisfaction. Conclusions: In order to enhance the adolescents' life satisfaction, we should make an effort to increase self-esteem, to prevent obesity, and to reduce depression through regular exercise and eating, adequate sleep. Therefore, it is important to recognize the importance of regular exercise and eating through health education. In addition, it is needed desperately to develop sleeping education program and to efforts to ensure sleeping right of adolescents.

The study is designed to grasp school adminstrators' attitudes toward school health education and practices of school health education and to analyse relationships between characteristics of school administators and their attitudes to school health education and between their attitudes and practices of school health education in elementary and secondary schools, so that it may offer the basic materials for improving the school health education. This study was obtained from 740 school administrators all over the country, who have attended Certification Training of Elementary and Secondary Principal opened at Korea National University of Education from July, 1, 1991 to August 9, 1991. The results are summarized as follows: 1. School administrators' attitudes toward school health education 1) As for view of health education, those who believed that health is the means of education was 36.2%. 2) In methods of school health, those who want regular health education was 75% ; irregular health education 25%. 3) As for attitudes of those chose irregular health education as teaching methods : (1) In teaching hours, the morning and afternoon class meetings was highest 50.8% of whole. (2) In teaching staffs, home room teacher was 51.9% ; school nurse 34.8%. (3) In frequency of irregular health education, 1-2 times a week was 38%, 1-2 times a month 32.6%, 1-2 times a semester 11.8%. (4) As for teaching methods of irregular health education, practice through the health function showed higher frequency than other methods 4) As for attitudes of those chose regular health education as teaching methods : (1) Most of respondents had opinion that regular health education should be carried out by the subject of physical education in both elemetary and secondary schools. (2) Opinion that school nurse should be in charge of regular health education was a little higher than other ones. (3) More than a half of the whole thought that 1-2 hours a month was suitable for carrying out regular health education. (4) Therr-fourth of those who wanted regular health education chose the using of audiovisual material as a teching method. (5) Curriculum recommended first by respondents for the school health education were personal habits and health, prevention and control of disease, mental and emotional health etc. (6) As for impedimental factors in the development of school health education, it was shown as following order : the lack of professional health education instructors, the lack of budget and administrative support, the lack of instructional materials and instruments etc.

We shall introduce new concepts of near-rings, that is, strong reducibility and left semi ${\pi}$-regular near-rings. We will study every strong reducibility of near-ring implies reducibility of near-ring but this converse is not true, and also some characterizations of strong reducibility of near-rings. We shall investigate some relations between strongly reduced near-rings and left strongly regular near-rings, and apply strong reducibility of near-rings to the study of left semi ${\pi}$-regular near-rings, s-weekly regular near-rings and some other regularity of near-rings.

The purpose of this study was to identify the differences in eye movement pattern shown in classification activities between the gifted and regular students in elementary schools. The subjects for the research consisted of five gifted students in the special education center for the gifted at Seoul National University of Education and five students at D regular elementary schools. SMI (Senso Motoric Instruments)' iView $X^{TM}$ RED 120 Hz was used in order to collect eye movement data. Results were as follows. There were difference patterns between the gifted and the regular student in question identification, attribute observation, and criteria generation process. Gifted students minimized unnecessary cognitive overload and took advantage of cognitive economic efficiency. Regular students have a lot of cognitive burden because they did not grasp the essential information.
