The researchers set up a research question to find out how to teach the concept of a right triangle through classification activities after listening to the conversations of fellow teachers about the recently revised textbooks. First, a questionnaire was created to confirm the objectivity of the research problem, data were collected through online and offline, and interviews were conducted with some of the respondents. As a result, it confirmed that there was a considerable difference in the perception of the research study about the direction of revising the curriculum called 'student participation centered' and 'the possibility of achieving the learning objective'. Then, we analyzed the critical interpretations used in the third grade math textbook Lesson 2. 'Plane Figure' part 4 and 5. Finally, by analyzing the results of the recognition analysis and textbook analysis, we proposed two learning methods which can link the triangle classification activity and the right triangle concept. Based on the results of the research, we obtained suggestions that a teaching should be made regarding that the classification process may be changed according to the student's prior knowledge and the process of classification activities may be different according to the viewpoint and classification criteria.

Rice is staple grain of our people and at the same time it is major source of income for Korean farmers. But recently various problems in connection with rice arose such as declining consumption etc. for this reason not only government but also related agencies are discussing about expanding vice consumption. This study is an attempt to provide basic data required for developing rice food and method of cooking it as a measure for increasing rice consumption and far this purpose survey has been conducted on primary school students in connection with their level of recognition, preference far rice food as well as their understanding and their consciousness on issues related to this topic. In terms of level of recognition of rice food majority of students which were subjected to this study stated that either they knew names of about 39 types of rice foods shown or had experience of eating them. They also stated in answers to question related to dietary habit that they prefer rice foods. Their reply on taste of rice food was plain and neat. But it was found their level of recognition on our traditional rice foods such as Ssal Dasik (rice cookies), Ssal Jinbyung (rice cakes) and Buggumi (fried rice cakes) etc. was very low. In connection with questions on their understanding of rice and consciousness of problems related to rice it was revealed that more than majority of primary school students in this research had erroneous idea on reason for the need of our effort for expanding rice consumption. Accordingly in order to expand rice consumption it is necessary to develop educational program addressing subjects of cultural and nutritional effect value of rice, effect of rice consumption upon rural economy and its application to school education concurrently with persistent study in order to diversify rice food restaurants and to improve method of cooking.

Objectives : We intended to evaluate the double standard status and to identify factors of determining double standard criteria in multinational corporations of Korea, and specifically those in the occupational health and safety area. Methods : A postal questionnaire had been sent, between August 2002 and September 2002, to multinational corporations in Korea. A double standard company was defined as those who answered in more than one item as adopting a different standard among the five items regarding double standard identification. By comparing double standard companies with equivalent standard companies, determinants for double standards were then identified using logistic regression analysis. Results : Of multinational corporations, 45.1% had adopted a double standard. Based on the question naire's scale level, the factor of 'characteristic and size of multinational corporation' was found to have the most potent impact on increasing double standard risk. On the variable level, factors of 'number of affiliated companies' and 'existence of an auditing system with the parent company' showed a strong negative impact on double standard risk. Conclusion : Our study suggests that a distinctive approach is needed to manage the occupational safety and health for multinational corporations. This approach should be focused on the specific level of a corporation, not on a country level.

This paper attempts to establish a scoring system for the originality in evaluation of mathematical creativity. The scoring system is composed of three categories; fluency, flexibility and originality. In this paper, we proposed an evaluation method for originality as following based on relative frequency and standard normal distribution. (1) Fluency: It is judged on the basis of the number of correct answers a student made. If several correct answers are given for a single category, then its maximum score is set to 5 points. (2) Flexibility: We examined how many categories the students' responses can be classified into. If at most 15 answers are allowed for each question, the maximum score of flexibility is 15 points. (3) Originality: Originality score is given if a student made some original response that other students did not show. That is, it reflects relative rarity. The originality is measured according to the following steps: Step 1: Analyze the frequency of how many students made an answer to the response type categorized at low level, and calculate the relative frequency p of each category. Step 2: Find the originality point os for each response, that is, os = max{0,z} where z satisfies P(Z > z) = p with standard normal distributed random variable Z. For example, - p is greater than 0.5: 0 point - p is 0.1587: 1 point - p is 0.0228: 2 points - p is 0.0013: 3 points Step 3: Assign the one's originality score to the sum of originality point for each response. Remark. There is no upper limit of originality score.

본 연구는 삼각형과 사각형 등 도형에 관한 정의와 성질 파악이 시작되는 4학년 단계에서 학생들이 범하는 오류를 연구해 봄으로써 적절한 처방과 교육 방법을 찾는데 목적이 있다. 4학년 단계에서 가장 많이 보이는 오류 유형으로는 정리나 정의를 부적절하게 사용하는 오류였으며 잘못되거나 제한된 개념 이미지가 크게 작용하였다. 이런 측면에서 본 연구는 용어에 대한 정의를 명확하게 하며 학생들의 기하수준을 높이는 지도가 필요하며 수학책과 수학 익힘책에서 제시된 도형 이미지는 제한적이므로 보다 다양한 위치와 길이의 도형이 제시되어야 하고 정확하게 서술되어야 하며 다양하고 실제적인 활동을 위한 방향으로 검토가 이루어져함을 시사한다.
