The primary purpose of this study was to investigate how number sense performance of sixth graders was and what every character of five components of number sense possessed by sixth graders was. For the this purpose, Two kinds of studies were conducted : a descriptive study by pencil-and-paper tests(Basic Test, Number Sense Test) and a clinical study by interviews. The conclusions drawn from the results obtained in the this study were as follows : First, students were highly scored in Basic Test but not highly scored equally in Number Sense Test. Second, students hardly used the benchmarks and lacked consideration of the reasonableness about computation results. Interview results were that students' notion about the meaning, and the greater - than and less - than relations for fractions was weak and students tended to not use number sense but apply standard algorithm and compute numbers in the question without thinking.

Based on the contents of probability and statistics areas in the seventh curriculum, we developed a statistics education model programmed by visual basic for upper grade students of elementary schools. The model that was consisted of ten modules can be easily manipulated by elementary schools students. The objects with a variety of colors are presented on P.C monitor and dynamic functions are performed by clicking a mouse. According to the survey after using the model, students positively evaluated the contents and characteristics and showed great interest in the model. We will upload the execution files of the model on our homepage. One can download and use them free.

The purpose of this paper IS to investigate the aspects of errors of English stress by Korean students. In this experimental study, 17 students participated and read 120 words which are divided into three types-the beginning, the middle, and the advanced-according to the level of words. As a result of acoustical judgement, there were a greater number of errors In the advanced level of words, and the more syllables the words have, the more errors occurred, tins means Korean students who learn English as a second language have trouble realizing the right stress in words with larger numbers of syllables and the more advanced level. Furthermore it is interesting that Korean students imposed the primary stress on the second syllable when producing words with stress in the first, third and forth syllables.

Adolescent smoking has been a great concern with respect to it’s causing more serious health problems than adult smoking. The smoking status and habits of middle school students were studied using anonymous questionnaires, and their dietary habits were compared. Ninety-two of 4l4 students (22.2%) had experienced smoking, and 62.0% of them began in primary school, mostly out of curiosity. The most plausible reasons for smoking were ‘boredom’ and/or ‘stress reduction’. Dietary habits were generally inadequate in the smoking group. Compared with the non-smoking group, the smoking group paid less attention to a balanced diet, more skipped breakfasts, more had irregular meal times and fewer snacked. There was no significant difference between the smoking and non-smoking groups in food intake frequency, except of sweet foods and caffeinated foods, which were more frequent consumed by the smoking group. These results suggest that more attention needs to be paid to nutrition and health education programs in elementary schools and also that proper support programs for smoking by themselves.

The survey was conducted through circulating questionares to three hundred sampled college students in Seoul. the findings are as follows. 1. 52% of MS (Male Students) and 25% of FS(Female Students) brought home-made lunches with them, while 39.2% of MS and 51.6% of FS used food services in campus. 2. Contents of home-made lunches were steamed rice(57%) or steamed ricebarley mix(24%) as a major diet, and Kimchi (Korean style pickled vegetable), fried eggs, soy-sauced sardins as side-dish. The favorite eating places for the students with home-made lunches were found to be campus dining hall for MS, classrooms for FS. 3. The primary reason for not having home-made lunches are the difficulties for handing. 4. The preference for the food served in campus dining hall was the traditional Korean food for MS and western style Snack (bakery and soft drinks) for the FS. 5. Costs spent for lunches were in the range of 200~600 won. 6. Followings are the comparison table for each ingredient compared with recommended daily requirement (RDR).

This study investigated the self-concepts of Korean students based on Marsh and Shavelson's(1985) multidimensional hierarchical model. Reduced forms of the Self-Description Questionnaire(SDQ)-I and -II were administered to 308 5th and 6th grade students and 718 7th to 9th grade students. Results of 2 factor analyses indicated that sub-scales 9 and 11 were well established for SDQ-I and -II, respectively, partly confirming the multidimensionality of self-concept. The factors involving distinctions between academic and non-academic higher-order factors and between the academic/math and the academic/verbal factors were not so differentiated nor hierarchically arranged as proposed by the model. These differences may be attributed to the heavy influence of the academic self-concept on the other sub-factors. A Locality ${\times}$ Sex ${\times}$ Grade ANOVA showed main effects of locality favoring urban areas and of sex favoring boys.

The objectives of the current study are on the practical use of geoboard in an elementary school class. To do this, we first investigate how come geoboard is significant in a practical use. Second, we present an example of practical use of geoboard connecting with the analysis of the 7th curriculum. Third, we investigate the results of geoboard which is applied to elementary school class. The results of this research are as follows: First, the instruction of using geoboard can give an interest and curiosity to all students. Second, right triangle, rectangle, square and so on can be easily constructed because geoboard is linked by dots. Third, by constructing figures on geoboard and comparing figures which is made by themselves, students could better understand the concept of figures rather than the explanation of teacher. fourth, students can be improved the ability of problem solving and spatial sense by providing experience for exploration. Fifth, students need not to have anxiety for error because geoband is used and so can be corrected easily.

To produce highly creative students, engineering education must develop both problem recognition skills and the ability to solve problems independently. Chonnam National University has been developing a creativity program in which students identify and solve problems themselves. Initially, the primary focus was on solving problems, but this was unsuccessful at attracting the students' interest. To overcome this, we adopted Csikszentmihalyi's flow theory in our creativity program, much like the way this theory is used in computer games. As a result of adopting flow theory, we achieved our goal. Thus, in this paper, we will introduce Chonnam National University's creativity program (designed based on flow theory), which we will call the Self-Directed Creativity-Upgrade Program. Furthermore, we will discuss the impact of this program based on statistical analyses.

The purpose of this study was to investigate culinary arts and hospitality students' food safety practice behaviors, intentions, attitudes, and barriers to food safety compliance. This descriptive study used the self-report questionnaire. The convenience sample was composed of 266 college students majoring in culinary arts and hospitality. The students indicated that they never or rarely use a thermometer to determine if meats have been adequately cooked. Examples of positive food handling behaviors were hand washing, sanitation of fruits and vegetables, discarding of food past its expiration date, counter top sanitation, and proper food storage. Students strongly agreed it is their responsibility to practice food safety and to educate their employees about food safety. The primary barrier to proper food safety as ranked by student respondents is the misunderstanding about food labeling. Previous food safety education and internship experience appeared to improve the student respondents' perceived attitudes toward following the principles of food safety practices (p < 0.05), although behaviors and intentions to use the correct food safety practices were not affected. The findings of this study suggest that programs should consider integrating information and experiential learning opportunities in their courses that would be enhance student understanding about food safety. The outcomes of this study can be applied to develop food safety education materials and programs for culinary arts and hospitality students.

Objectives : The purpose of this study is researching for possibility that Moire topography be applied in group school screening for scoliosis known school health problem, and find acceptable method of early detection and early treatment for scoliosis Methods : The authors practiced Moire topography for primary & middle school 1,895 students[male 976, female 919] in Jeonju, korea in 2001. After we distinguished students who had abnormal finding in Moire topography and then re-examined spinal X-ray analysis. The data was analysed and evaluated statistically Results : According to this research, the abnormal finding in Moire topography was 53.7% (1,018 students), and students needed X-ray re-examination were 11.2% (213 students). Students diagnosed scoliosis by X-ray re-examination were 1.8%. According to statistical analysis, interval between vertical base line of pelvis and vertical base line of neck, gap between left distance and right distance to the vertical base line of pelvis and difference of contour lines have strong correlations with deformity degree of the body surface examined by Moire. Conclusions : Following this research, throughout early detection for scoliosis by Moire topography could reduce exposure from scoliosis radiographs, and could detect trunk asymmetry that couldn't be found existing X-ray examination, so it made selecting students under observation who have bad posture possible.
