The nutrition knowledge and food attitude of obese children were assessed and compared with their normal children counterparts to provide information for nutrition education programs. One hundred forty six obese children and 92 normal children from the fourth to sixth grade in Bucheon and Anyang elementary schools of Kyeong-gi Province were selected for the study. A multiple choice questionnaire, including 12 items of general nutrition knowledge and 13 items of weight control, were used to test the nutrition knowledge of children. The results of this study are as follows : 1) 57.5% of male and 40.9% of female obese children had experience with weight control, but the rate of correct answers on the nutrition knowledge test ranged from 53% to 58%, which does not show any significant difference between the two groups. The rate of correct answers on items conrerning 'general nutrition knowledge' and 'nutrition knowledge for weight control' did not show any significant difference among the two groups. 2) Obese male students showed a higher rate of correct answers(59.2%) on items of 'the proper food selection for obese children', compared with their counterparts and also obese female students showed a higher rate of correct answers(88.6%) on 'physical exercise', compared with their counterparts. 3) The rate of correct answers on nutrition knowledge of 'basic food groups', 'the functions of iron and vitamins', 'the concept of energy', and 'the principle of weight change' were lower than 40%. 4) The obese children frequently did not have breakfast, overate during lunch in many cases, and had low recognition on knowledge that was necessary to weight control. 5) Only 30.9% and 22.7% of male and female obese children replied that they would participate in weight control programs. However, 53.6% of males and 68.2% of females did not show any concern in participating the programs. From these results, it was suggested that it is necessary to motivate the obese to participate in weight-control program. When developing nutrition education programs for the obese, the contents of the questions that showed a low correct answering rates should be emphasized.

The research which it sees against the self concept of part dental hygienes students from the hazard which it examines dental hygienes which is located on Kyoung-Buk and students 318 people in the object un-signature it enforced a research with the entry method which it got a same result. 1. From general characteristics of part hygiene students "the employment went well from the motive which selects hygiene" and it appeared most highly. The employment will go well and the social advance will do and ease when seeing specially with characteristics of college, it has an corresponding with the fact that is a possibility of employment.. 2. The average score against the self concept of part hygiene students "me it is an existence which is isolated from this world and nothing to do with the others". It appeared most highly with 3.52. The negation self concept appeared more highly affirmative self concept than. 3. To self concept and grade, religion, health condition, hygiene selection motive, subject record and native high school of part hygiene students the difference which considers statistically did not appear(p>0.05). However it tries to observe the self concept which it follows subject satisfactory degree, it is very unsatisfactorily(3.37) with it is unsatisfactorily(3.16) gaps it was not visible the difference which considers statistically, it is very satisfied(3.37) with the difference which considers statistically it was visible(p<0.05). Students the affirmative reaction is correct phenomenon in order to establish a specialty intuition. 4. When self concept and record and the subject satisfaction sees a interrelation for, Between self concept subject satisfaction is appeare big affirmative interrelation(r=0.331) and the subject record and subject satisfaction just interrelation appeared as well(r=0.282) all they considered statistically and appeared.(p=0.000) but to self concept and subject record for the interrelation did not appear. Negation self concept of part hygiene students appears more strongly than affirmative one, And studying for self concept of the students, it leads through the program which is the possibility to pull affirmatively is demanded.

The Principle of space composition in modern architecture is thought about functionalism that based on function and program but the present age attempt that escapes form of former space composition. The present age brings fast development than former ages, so we need the space which has correct flexibility on New Age for escaping in existing structural formality. Specially, the space that boundary of existing plate, column and wall is crumbled as becoming possible technological support with social backgrounds. What this study saying is the analysis about the relation between the concept of topology and the consecutive space composition. Therefore, there is the purpose understanding a characteristic of continuity of the plate through the topological concept and understanding the roll in interior space.

많은 학생들이 전류에 대한 오개념을 가지고 있고, 이러한 오개념은 전통적인 교육방법에 의해 쉽게 교정되지 않는다. 본 논문은 전류에 대한 오개념 교정을 위한 멀티미디어 타이틀을 개발하여, 학생들에게 적용하여, 오개념 교정의 효과를 분석하였다. 실험 대상은 중학생 32명을 대상으로 하였고, 실험집단은 개발된 멀티미디어 타이틀을 적용하였고, 비교집단은 전통적 강의 수업을 실시하였다. 실험 결과는 SPSS 프로그램을 이용하여 t-검증을 통해 분석하였다. 분석 결과 전류 소모 개념은 수업 방식에 관계없이 비교적 쉽게 교정될 수 있는 오개념임을 보여주고 있다. 전류의 분배 개념은 전통적인 수업 방법으로는 잘 교정되지 않았으며, 멀티미디어 타이틀을 가장 효과적으로 활용될 수 있는 오개념이라고 할 수 있다. 전류의 저항 무관 개념은 가장 적은 학생들이 오개념으로 가지고 있었지만, 전통적인 수업 방식이나 멀티미디어 타이틀을 적용한 학습으로도 교정되기 어렵다는 분석 결과이다.

One of the major characteristics in misconceptions is the stability over time. However, the concept of stability has not been defined clearly yet even though some trials to quantify the stability has been done. In this study, the researcher tried to establish a stability index of students' misconception for the quantification. In this study, the stability of a misconception was defined using mean correct choice (MC), the slope of correct choice (C), mean incorrent choice(MI) and the slope of incorrect choice(I) as follows; I=1/3 (1-C) (1+I)(1-MC)(1+MI). The index developed in the study was examined using artificial data. In this study, the index seemed to represent the charicteristics of the stability inferred by theoretically. This means the index developed in this study has some validity for the time being. Howerever, since artificial data were used to exame the index, it showed be reexamined using real data in the future study.

Products are often evaluated on rating scales to measure and quantify their attributes of interest. In case that one wishes to compare multiple rating datasets simultaneously, there must be a standardized scale with which one can discriminate relative differences among corresponding scale means. In this regard, the concept of Thurstonian modeling applied to various discrimination tests including the triangular method has been recently being reconsidered. In this paper we extend previous researches on the triangular method and evaluate the effect of unequal variances and correlated variables upon the probability of correct response using Monte-Carlo simulation. We observed that the probability of correct response depends on dimensionality, variances, and correlation structure of stimulus sets. But it does not depend on the relative orientation in a multidimensional space.
