  • The purpose of this study was to investigate the recognition degrees of contents in Home Economics textbook for middle school students among pre-middle school students and their parents. It is for developing better Home Economics textbook. Three objectives of this study were ; 1) To find the recognition degrees of the fact that Home Economics subject is supposed to utilize for not only girls, but boys students in middle schools in 1996 among pre-middle school students and their parents. 2) To find the degrees of necessity in each field of Home Economics subject among pre-middle school students and their parents. 3) To find the differences in recognition degrees of understandings, attitudes, and sills of Home Economics subject between pre-middle school students and their parents. Questionnaire survey method was utilized to 1,205 sixth grade students and their parents in Pusan. The results of this study as follows; 1) It was low that the recognition degrees of the fact that Home Economics subject is supposed to utilize for both girls and boys in middle school among both pre-middle school students and their parents. This result implies that it is important to important to disseminate the curriculum change in Home Economics practice to the public. 2) It was high that the recognition degree of necessity in each field of Home Economics subject among pre-middle school students and their parents. The recognition degree were different according to sociodemographic factors. That is , $\circled1$the recognition degrees of students were lower than their parents; $\circled2$ the recognition degrees of parents who have high education were higher than those who have low education ; $\circled3$ the recognition degree of an environmental field was highest. 3) There were little differences between pre-middle school students and their parents in the recognition degrees of understandings, attitudes, and skills of Home Economics subjects: The recognition degrees of girls fathers showed higher scores than boys fathers those of in understandings and skills of Home Economics subject. The recognition degrees of girls fathers showed higher scores than those of girls in attitudes of Home Economics subject.

  • This study was conducted to evaluate the sanitary performance and education of middle and high school foodservice employees in Seoul, South Korea in order to ensure the foodservice safety and identify why some employees cannot apply learned knowledge in real work situations. Subjects consisted of 217 school foodservice employees who attended a regular sanitary education program under the auspices of the Seoul Gangdong and Gangseo district offices. The sanitary performance was assessed with 5 dimensions (personal hygiene, ingredient control, process control, safety management and sanitary education), and was self-evaluated using a Likert 5 point scale. The data were analyzed using the SPSSWIN Version 12.0 package. The main results of the study showed that according to the general characteristics of middle and high school foodservice employees, 98.2% of respondents were women, and 64.1% of them aged 40-49. A total mean score of 5 items of sanitary performance for middle and high school employees was 4.74. Ingredient control field score was 4.83, process control 4.80 and personal hygiene 4.74. In contrast, the sanitary education field score was 4.56, significantly lower than the total mean score. Safety management field score was 4.71. Verbal education was the main method performed as a sanitary education in schools.

  • This paper describes the influence of conducting particle in the coaxial cylindrical electrodes under alternating voltage condition investigated using breakdown electric field and electro magnetics simulation method. Simulated particle-location in GIS chamber were the particle on electrode, the particle on enclosure and free moving particle. As results, it was founded that in case of breakdown electric field of the GIS chamber, breakdown electric field of particle on electrode was the lowest, that of free moving particle was middle and that of particle on enclosure was the highest. And in case of the electric field analysis with particle locations, electric field of particle on electrode was the highest that of lifted particle was middle and that of particle on enclosure was the lowest. This results can offer a practical reference ra the insulation design of domestic GIS.

  • Probability and statistics is an important section in mathematics which is deeply related to everyday living, natural science and social science. In spite of its importance, many students will throw away it because it becomes very harder as its step(stage) deepens and probability and statistics' relative importance is very small in Korea-SAT(the test of college entrance in Korea). Therefore, by analyzing the involvement carefully between the curriculum in the elementary, middle, high school and the text book, by studying the problem and improvement direction, it is necessary to investigate an effective teaching method. This study intends to give the students the confidence, interests, and accomplishment motive about probability and statistics field and to make a rational and creative decision-making through mathematical speculation by proposing an effective teaching method through analyzing an existing facts in school's probability and statistics field. The contents of this study are composed of four chapters. Chapter three looks into the mathematical curriculum in the elementary, middle, high school and its teaching meaning, the outline of contents, some tips on teaching and problems and presents an effective and concrete teaching method on the basis of the theoretical background in the chapter two. Chapter four is a conclusive part and gives the general improvement and intentional direction in educating the probability and statistics.

  • 본 연구는 중학교 체육교사들이 체육교육 현장에서 겪는 다양한 갈등경험을 현상학적 방법을 통하여 그 의미를 심층적으로 이해하고 분석하여 그 본질을 교육학적으로 탐구하는 것이다. 연구방법과 관련하여 연구 참여자는 현직 중학교 체육교사 4명이며 질적 연구방법론의 하나인 Colaizzi의 현상학적 연구방법을 통해 본 연구를 수행하였다. 연구 결과는 다음과 같다. 첫째, 일반적 갈등은 교사와 학생의 갈등으로서 학생지도 및 인간관계로 범주화되었다. 둘째, 직무 갈등은 교사와 교사의 갈등으로서 교직 문화 및 의사소통으로 범주화되었다. 셋째, 관계 갈등은 교사와 학부모와의 갈등으로서 역할기대 및 권력 행사로 범주화되었다. 결론적으로 중학교 체육교사가 경험하는 갈등의 양상을 심층적으로 분석함으로써 다양한 갈등을 효과적으로 해결하고, 특히 교육 현장에서의 갈등을 최소화하여 보다 긍정적인 교육 환경을 조성할 수 있도록 해야 할 것이다.

  • In this paper, descriptive assessment method for middle school mathematics was evaluated by developing a framework for designing and grading problems for descriptive assessment and analyzing the effectiveness of the problems. The new descriptive assessment problems were developed by reviewing the current 7th National Mathematics Curriculum of Korea and aligned mathematics textbooks to define a set of problem design principles and evaluation framework for the assessment strategy. The developed problems were first pilot tested and then revised based on the feedback from the test. The final version was field tested by 100 students in 7th grade middle school. After the field test, the problems were graded by two middle school math teachers and one math education researcher to determine the overall correlation between graders and also to analyze effectiveness of the evaluation framework of the test. This result of this study is expected to assist in the further development of descriptive problems and grading framework by providing a reference work for teachers to better understand the process and the limitations of executing the new assessment strategy.

  • This thesis attempt to explore the shape of stress wave propagation of 3-dimensional stress field which is made in the process of time increment. A finite element code about 3-dimensional stress wave propagation is developed for investigating the changing shape of the fracture by the impact load. The Finite Element Code, which is the solution for the 3-dimensional stress wave analysis, based on Galerkins and Newmark- .betha. method at time increment step. The tensile stress and compressive stress become larger with the order of the middle, the upper and the opposite layers when the impact load is applied. In a while the shear stress become larger according to the order of the upper, the middle and the opposite layers when impact load applied.

  • 전계해석법을 이용하여 나타내었다. 이때 모의한 GIS 챔버내 금속이물의 위치는 전극부착시, 외함부착시 그리고 자유운동시로 하였다. 그 결과 GIS챔버의 절연파괴전계의 경우, 전극에 파티클 부착시가 가장 작게 나타났고, 파티클 자유운동시가 중간, 외함에 파티클 부착시가 가장 작게 나타남을 알 수 있었다. 또한 파티클 위치에 따른 전계해석의 경우 전극에 파티클 부착시가 가장 크게 나타났고, 파티클 자유운동시가 중간, 외함에 파티클 부착시가 가장 작게 나타났다. 이 결과는 국내 GIS의 절연설계에 설제적인 참고자료가 될 것으로 사료된다.
