Recently, the interdisciplinary integration and story-telling are often mentioned in mathematics education. It is probably because they might be helpful to students for positive attitude for mathematics. In this research, through brief discussion mathematics related with wallpaper patterns, we try to integrate mathematics and design, and eventually develop the teaching/learning materials for experience activities and story-telling.

The purpose of this study was to investigate the performance of elementary school dietitians in terms of nutrition education in the northern portion of Gyeonggi province. Self-administered questionnaires were given to 50 dietitians who have worked in elementary schools with self-operation food service, and 35(70%) dietitians returned the questionnaires. The results are summarized as follows: no students took part in nutrition education as a regular course, but all dietitians performed nutrition education in passive ways, such as 'using home correspondence'(39.0%), 'bulletin board/poster'(22.0%), 'using the internet'(13.4%) and 'indirectly through a classroom teacher'(12.2%). Most respondents performed nutrition education 'one time/month'(66.0%) or 'one time/week'(20.0%). The respondents thought that suitable teaching times for nutrition education were 'during a related subject'(35.5%), 'during lunch time'(22.6%) rather than 'during an independent subject'(16.1%). Most of the dietitians(94.3%) did not perform nutrition counseling because of 'a lack of opportunity'(72.7%) and 'workload'(27.3%). Additionally 88.6% of respondents did not have the time of for nutrition counseling for parents because 'am not a teacher'(56.7%) and 'workload'(30,0%). Information sources for nutrition education were mainly 'internet'(71.4%) and 're-educationa1 materials'(17.1%). They possessed instructional materials in the forms of 'printed materials'(35.1 %), 'exhibition/bulletin board'(31.2%), and 'electrical materials'(33.8%), 'but did not have 'solid materials' such as food models and dolls. Generally they had mostly 'leaflets'(82.9%), 'bulletins'(68.6%), 'internet'(57.1%), and 'CDs'(57.1%). Preferences for instructional materials used were 'printed materials'(46.2%), 'exhibition/bulletin board'(36.5%), and 'electrical materials'(17.3%) 'Leaflets'(80.0%) were mainly used; 'CD'(17.1 %) use was low compared to the proportion possessing CDs. The topics frequently chosen by the subjects for nutrition education were 'table manners'(82.9%), 'basic concepts of food and nutrition'(80.0%), and 'proper food habits'(80.0%), but the topics helpful for practical use, such as 'how much do I eat'(20.0%) and 'nutrition labeling'(37.1%), were not included frequently. The respondents thought that 'eating only what they like'(60.0 %), 'intake of processed foods'(17.8%), and 'obesity'(17.8%) were the most common nutritional problems among elementary school children. They also thought that establishing a regular course for nutrition education was an effective way to cut down on these nutritional problems. In conclusion, nutrition education programs that are combined with effective instructional materials and practical topics should be developed. Additionally, it is recommended that dietitians act as teachers who participate in regular courses as soon as possible.

The purpose of this study was to survey the actual condition about field learning materials in Gwangju and Jeonnam area. The questionnaire was developed to examine teachers' perceptions and actual condition of a field teaming related science subject at 145 elementary schools in Gwangju city and Jeonnam province. The results of this study were as follows. First, the rate of school in performing field teaming related to 'strata and fossils' in science class was $6.8\%$. Second, the place of dianosaur track fossils in Jeonnam province, which was suitable for field teaming 'strata and fossils: were well known by $75\%$ of teachers. Also $68\%$ of teachers have not visited those places. On the basis of this result, the followings are proposed. First, field teaming materials and place should be developed in each school district. Second, field teaming strategies should be developed in various level. Third, some programs to study how to teach in the field teaming and experience the various field places should be suggested to preservice teachers as well as inservice teachers.

The purpose of this study was to examine the status and science teachers' perceptions of classes for those gifted in science in elementary school. For this purpose, a number of questions were posed to teachers : 27-item-questionnaires were given to 38 teachers of students gifted in science in elementary schools located in Incheon province. The results of this study were as follows : 1. most elementary teachers were in charge of classes containing students gifted in science, but this was the case with only a few secondary teachers. Therefore, it appears to be more necessary to educate elementary teachers who majored in science content and gifted education. 2. In addition, most teachers had positive perceptions of the needs, attitudes and environments needed for gifted education. Most of them attended 60-hour training programs on gifted education. They thought that it was helpful in understanding the characteristics of gifted students, but they wanted to learn more about actual pedagogical methods through such programs. 3. The teaching methods used in classes for those gifted in science were mainly experimental activities, but there were few opportunities for creative problem solving and project learning. This may be due to limited class time of about one hour every two weeks in this class. 4. When the materials used in class were first developed, they mainly used materials made by the city board of education and selected the theme of interest by themselves. Therefore, there may be problems of duplication of materials or systems regarding the science contents for one year. 5. Furthermore, the themes of the materials used were mostly related in terms of the contents of textbooks than more generally. When planning and managing the classes for those gifted in science, the above points should be considered in order to improve the education of those students gifted in science.

The purpose of this study is to investigate the perception about STEAM education of primary teachers who have developed and applied STEAM education to their students through teacher training program. For this study, 101 among 172 attendance are responded to questionnaire of three categories consisting of development and application teaching material for STEAM instruction, and spreading STEAM education. The major findings are as follows: First, when primary teachers develop materials for STEAM education, they consider applicabilities in real classes. Second, they feel the burden of time when they develop STEAM material. Third, they think that their own program has significant educational effectiveness and that students enjoyed the program. Especially, they think that STEAM education program can raise students' interest about learning. Fourth, primary teachers point out the constraints for application of STEAM education program, which are lack of expertise and difficulty acquiring class time. Fifth, primary teachers evaluate the effect of STEAM education program on primary education is positive, and they answer that we need many teaching materials for STEAM education, operating as a regular curriculum, and securing budget. In order to spread STEAM education in field of primary education successfully, administrators have to consider and reflect the voice of teachers.

We fabricated In₂O₃ zig-zag nanocolumns(ZZNCs) by oblique angle deposition method based on e-beam evaporator for highly sensitive and selective CH₃COCH₃ sensor. Our results indicate that as the ZZNCs layer stacks, the gas response also increases. In comparison to thin films, ZZNCs at 5 layer show a 117-fold enhancement in gas response and a rapid response time (~2 s). When measured with various gases, it showed a high selectivity towards acetone. Under conditions of 80% R.H., exposure to CH₃COCH₃ gas theoretically indicated a detection limit of 1.2 part-per-billion(ppb). These results suggest the potential of In₂O₃ ZZNCs as a breath analyzer for the diagnosis of diabetes.

This paper presents the status of nutrition education for older adults in Korea, and examines considerations in developing effective nutrition education programs for the elderly based on literature reviews. Finally, strategies of nutrition education for older adults in Korea are examined. Status of nutrition education were examined by surveying 90 senior centers, and 46 public health centers providing nutrition services. Most senior centers(96%) provided health education programs, however, nutrition was only a part of health programs. Among the 41 public health centers which responded to the survey, 73.1% provided nutrition education for older adults. The frequently covered topics were prevention & management of hypertension/stroke, diabetes, nutritional management during later adulthood, and osteoporosis. Common barriers in planning and implementing elderly education were; lack of educational materials for older adults, reliance on lectures, difficulty in following-up. To develop effective nutrition education, four stages consisting of needs assessment, planning and implementation of programs, and evaluation should be carefully done. Needs assessment might be done using quantitative or qualitative assessment. Factors influencing nutrition behavior of older adults can be systematically examined using a theoretical approach such as the PRECEDE-PROCEED framework. Qualitative methods, such as focus group interviews, also provide insightful information regarding the needs of older adults. In planning nutrition education programs, physical and pshychological changes associated with aging should be considered. Literature regarding elderly education suggest that active participation or participatory learning is also effective for older adults. Educational materials are developed following the principle of KISS and pre-tested. Program evaluation has been rarely done in practice, although it provides valuable feedback to the program. Strategies for developing nutrition education for Korean elderly include; performing needs assessment, developing a standard program by topics in a logical and systematic way, developing programs for subgroups of elderly, applying diverse education methods developing educational materials for the elderly, evaluating programs using simple tools, and delivering a nutrition program as a part of health promotion program. Finally, the interaction and communication between researchers and practitioners is strongly recommended to ensure better nutrition education and services to the elderly.

In this article we study on various proofs and applications of the Cauchy inequality. Prof, Park H.S. claims that though “Mathematics for teachers” is not compulsory materials in school, it gives to mathematics teacher feeling of reassurance in the process of teaching mathematics. In our work, we review some materials concerned with Cauchy inequality, elaborate these, and develop materials for the mathematics teacher. We think that our materials are suitable to contents of “Mathematics for teachers”.
