This research investigated the effect of story-plotting and oral narration activities using wordless picture books upon young children's linguistic creativity and expression. The subjects were 30 children of experimental group and another 30 in the control group at age five. The Korean Comprehensive Creativity Test for Young Children(K-CCTYC; Jeon, 2005) was used to measure linguistic creativity. In addition, Measure Tools for Linguistic Ability(Jang, 1981) was used to measure the linguistic expression. There were significant differences between the two groups in linguistic creativity including linguistic fluency, flexibility, and originality as well as linguistic expression.

The purpose of this study was to examine the effects of cookbook making activities on young children's mathematical concept and writing development. The participants were comprised of 50 five-year-old children from two intact classes from a kindergarten in Gyeonggi province, and they were divided into an experimental and a comparison group. The experimental group participated in cooking activities and produced cookbooks as extension activities whereas the comparison group carried out only cooking activities. The results indicated that the children in the experimental group received statistically higher scores in mathematical concept- and writing-tests, suggesting that cookbook making activities are a useful educational tool for enhancing young children's mathematical concepts and facilitating their writing development.

Acne vulgaris, the most common skin disease. can be formed as only a few comedons or severe inflammatory lesions. The pathogenesis of acne involves various factors; excessive androgen, excessive sebum production, abnormal alteration of follicular epithelium, proliferation of Propionibacterium acnes, and inflammation. We investigated acne therapy using oriental herbs described in the Korean traditional medical book(Dong-ui-bo-gam). Oriental herbs(Angelica daurica, Arctium lappa, Coptidis rhizoma, and Glycyrrhiza glabra) were chosen based on their respective property of sebum control, anti-inflammatory activity, and anti-bacterial activity. We examined the effect of acne treatment, in terms of chemotactic inhibition, lipogenesis inhibition, and anti-bacterial activity for P. acnes. 1. Neutrophil chemotaxis assay; P. acnes secrete chemotactic factors and other pro-inflammatory extracellular products. Neutrophil chemotactic activity of P. acnes was measured by 48-well chemotaxis method. Angelica daurica clearly suppressed chemotactic activity of P. acnes. 2. Using sebaceous gland of hamster ear lipogenesis assay; Sebaceous lipogenesis was measured using ear biopsies by incubation or $C^{14}$-acetate in culture media. The $C^{14}$-labeled lipids were extracted and determined by liquid scintilation counting. Coptidis rhizoma markedly inhibited sebum production. 3. Anti-bacterial assay for P. acnes(MIC test); Glycyrrhiza glabra showed anti-bacterial activity. P. acnes did not develop resistance against Glycyrrhiza glabra. Retinoids are effectively to inhibit sebum production and regulate follicular keratinization process, with little anti-inflammatory activity. Angelica daurica suppressed neutrophil chemotaxis, Coptidis rhizoma inhibited sebum production, and Glycyrrhiza glabra showed anti-bacterial activity against P. acnes. A combined formulation of Angelica daurica, Coptidis rhizoma. and Glycyrrhiza glabra is expected to provide effective acne treatment.

Objectives : This studies were carried out to evaluate the effects on anti-oxidation activities in different parts as trunk bark and root bark of Ulmus devidiana Planchon. var. japonica Nakai and Hemipteleae davidii (Hance) Planchon. Methods : For evaluation of antioxidative effects, scavenging activity on superoxide anion radical and DPPH radical were measured. Also, inhibitory activity on LDL oxidation and linoleic acid peroxidation were measured in each samples. In the in vivo test, inhibitory activity on TBARS production, GSH contents in rat liver were measured. SOD, Catalase, GSH-px and ALDH activity were analysed in ethanol extracts of Ulmi Radicis Cortex. Result : 1. Scavenging activity on superoxide anion radical was higher in water extract than in ethanol extract even in low concentration of 50ppm as over 90%. 2. There was no difference between water extract and ethanol extract in the scavenging activity on DPPH radical but, Ulmi Raclicis Cortex and Ulmi Trunci Cortex showed high effect even in low concentration of 10ppm. 3. GSH reduction was prevented and antioxidative activity such as Mn-SOD, GSH-px in the rat liver recovered in the treatment of ethanol extracts of Ulmi Radicis Cortex. Conclusion : Ulmi Radicis Cortex recorded as Ulmi Trunci Cortex in official regulation book. But, it was known that Ulmi Radicis Cortex was more effective than Ulmi Trunci Cortex in most physical activities.

The purpose of this study is to find out the effect of the role-playing analogy activity-based class on the academic achievement in science and the science process skills of elementary school students. One experimental group and one control group of 4th grade students were selected to perform a prior investigation on the academic achievement in science and the science process skill. Then the experimental group attended science lessons that were based on the role-playing analogy activity and the control group attended the traditional science lessons based on the text book and teacher's guide. After conducting lessons, a post investigation was performed for each group and the results were analyzed to produce the following conclusions. First, the role-playing analogy activity class was more effective to improve students' academic achievements than the traditional science class. And the role-playing analogy activity class was more effective to learners in the high-level group, which made a scores above the average in prior investigation on the academic achievement, whereas it was little effective to those in the low-level group. Second, the role-playing analogy activity class was effective to enhance students' science process skills than the traditional science class. And the role-playing analogy activity class was more effective to the learners' in the high-level group than those in the low-level group.

This study aims to discover how three-year-old children to search for existence and its meaning, while they participate a programme, 'discourse among children through books' as a way of resolving curiosities. Data were collected between April 2, September 10, 2010 and the collected data included teacher's class records, pictures, discussion notes and interview materials. The results showed that 'discourse among children through books' follows steps in a process. The steps include: Deciding a topic that children should search for, choosing an appropriate book to resolve children's curiosities, spending some time for discoursing among children by using pictures in the book, and sharing what they had understood. Through this process, a pre-school teacher met with children who were full of abilities, ideas and motivation to explore with a little assistance. The pre-school teacher was able to overcome preconceived ideas that informational books could be difficult for children, and experienced various lessons, while the children led their own learning. It represents that the activity, 'discourse among children through books' can be a children centered inquiry learning teaching strategy, because the informational books ensure that the children gain knowledge and are actively in cogitation.

In this study, connections between the NURI curriculum for 5 years old children and the contents of teacher's manual books according to it and the contents of elementary 1st grade mathematics curriculum and textbooks was analyzed to find the implications that can help to link the two curricula in the development of kindergarten and elementary school mathematics curriculum. The five following implications could be obtained from the analysis. First, it is necessary to connect the contents of the NURI curriculum for 5 years old children which were completed in that curriculum like 'spatial relation'in geometric figure domain and 'data collection'in probability and statistics domain to the contents of the 1st grade curriculum. Second, in the case of the contents not connected between the NURI curriculum for 5 years old children and the contents of elementary 1st grade mathematics curriculum but connected between the NURI curriculum for 5 years old children and the contents of elementary 2nd ~6th grade mathematics curriculum, it is necessary to re-adjust the hierarchy based on one of the curricula. Third, it is necessary to check whether $\ll$K-teacher's manual book$\gg$ obey the NURI curriculum for 5 years old children or not. Fourth, it is necessary to review the related elements of the NURI curriculum for 5 years old children and elementary 2nd ~6th grade mathematics curriculum in [activity] in $\ll$K-teacher's manual book$\gg$. Fifth, it is necessary to handle the mathematics contents explicitly and systematically in [activity] in $\ll$K-teacher's manual book$\gg$.
