In this paper I analyzed mathematics textbooks of elementary school in 1st curriculum. I found that they used the natural closed items and children's play. And they also delayed the introduction of the symbol and letters. Finally they had the system to practice what students learned repeatedly.

The purpose of this study was to analyze the relationships on participation on health education program toward skin care and the improvement of healthy life habit. The subject of the study was selected by multi-stage stratified cluster random sampling among the skin care education center to learn health education program toward skin care among women in the Seoul and Kyunggi area. The data were collected through a questionnaire adapted from Payne and Hahn's(1986) 'Understanding Your Health-A personal profile; Evaluating Your Health'. The pilot test was executed after the questionnaire was translated into Korean. The statistics employed the study were validity and reliability test, $x^2$ verification, frequency, ANOVA, multiple classification analysis, ANCOVA and Multiple Regression Analysis. The results that were derived from these processes were as follows: First, before and after on health education program toward skin care, the student's healthy life habit is partially changed. Second, the relationship the period of education program and the characteristic healthy life habit, long-term skin care education is positively affected sleeping habit, anti-stress treatment, exercise and nutrition. Third, the relationship on the frequency of education program and the characteristic healthy life habit, more frequently participation on skin care education is positively affected on healthy life habit and exercise.

The purpose of this study is to examine North Korean defector students' characteristics in science learning through their voice in an "Angbuilgu" program, one of the Korean traditional science knowledge (TSK). We compared them with two other groups of contrasting backgrounds. The Angbuilgu program contains meaningful questions of time, everyday-life knowledge, Korean TSK, and western modern science (WMS). The teaching strategy consists of interactions between teacher and students, and scientific experiments. We applied this program to three groups and analyzed: North Korean defector students, elementary science gifted students, high school students in an advanced class. The characteristics of their science learning show the following: First, their interpretation of time as nature itself in their everyday life. They have rich experience and are familiar with time in nature. Second, they prefer science with complementary, caring, and humanist perspectives, which is in contrast to other groups with preference to the updated and practical science. Third, they lack scientific concepts but possess an abundance of everyday-life knowledge. Their linguistic expressions are ordinary rather than scientific. Fourth, they are familiar with narrative thinking more than scientific thinking. The results show that the science program using Korean TSK can help them accept new scientific knowledge as well as cultural pride, which plays a role in reconfirming their identity as one ethnicity. We expect that the contents of Korean TSK can be an intercultural field between North Korean defector students and our science curriculum.

Lips have a unique desquamation process and moisturizing properties that are structurally different from ordinary skin. In particular, the turnover cycle of the stratum corneum is fast and the outermost stratum corneum is thin, so the amount of keratin is relatively high, and there are no skin appendages, so it is very vulnerable to maintaining moisture. In this study, we set three targets for lip care : stratum corneum, moisture, and barrier, and aimed to identify the potential of three target-specific ingredients for lips improvement. We confirmed the exfoliating, moisturizing, and barrier improvement efficacy of three target-specific ingredients which also have mild exfoliating effect. Specifically, we verified that Bacillus clausii extract improved skin exfoliation, gluconolactone improved skin moisture retention, and serine reinforced skin barrier function. To test the in vivo efficacy of the complex composed of three target-specific ingredients on the human lips, the lip balm manufactured with non-irritating range of concentration was applied, and we confirmed that it was effective in improving lip exfoliation·moisturizing·elasticity·wrinkles. Consequently, it was confirmed that the beauty and health indicators of the lips could be improved through the exfoliation-moisturization-barrier care of the lips and these ingredients were applied to LG H&H LIPCERIN products.

The trends of plant-related teaching and learning of elementary and secondary schools were presented in this paper. The textbooks of other subject matters except biology were analyzed for their plant-related learning contents. It was suggested that interconnection exists between biology and other subjects in the relations with plant-related learning materials. A total of 331 books were analyzed from 143 elementary schools, 117 middle schools and 71 high schools. 1. Among the learning materials, 264 species of plant were presented in elementary schools textbooks, 295 in middle schools, and 283 in high schools. Other subjcets had more various plants than biology. 2. Korean language, social study and home ecology had more plant materials than other subjects with not only simple citation but scientific concepts and inquiry activities. As this plant-related materials is considerable for school education and science curriculum. 3. The available plants in daily life - resource plants, edible plants, demonstration plants and engineering-related plants - were cited in other subjects. Interconnection of plant-related materials with biology and other subjects will provide basis of STS education and subject integration.

최근 국민소득의 급격한 증가와 더불어 식생활 패턴에도 커다란 변화를 나타내고 있다. 식생활에 있어서 기호의 다양화, 생활의 고도화 그리고 식품가공기술의 발단과 더불어 편의 식품등 가공식품의 보급이 급속히 증가하고 있는 실정이다. 가공식품 산업의 역할은 보존성, 기호성 및 편리성의 향상이며 이중에서 특히 기호성의 향상은 빼놓을 수 없는 중요한 역할이라 할 수 있다. 기호성의 향상에 가장 밀접한 관련이 있는 것이 조미료이며 식생활의 다양화, 고급화에 따라서 조미료의 사용에 있어서도 종전의 글루타민산 나트륨(mono-sodium glutamate)으로부터 동식물 엑기스 등의 천연 조미료를 이용하려는 변화가 오래전부터 일고 있다. 천연 조미료가 소재가 될수있는 소재는 동식물성 식품중 여러가지 종류가 있으나 그중 축육류는 풍부한 영양성과 더불어 소비자의 기호성이 높을 뿐만 아니라 독특한 향미성이 있어 각종 조리 및 라면스프, 육제품등 가공식품의 조미 소재로서 이용도가 날로 증대되고 있다.
