This study compares, analyzes and reevaluates color conditions and images before and after the execution of the 7th curriculum with elementary schools in Gwang-ju Metropolitan City based on the fact that color among physical environments of elementary classrooms has an important influence on children's emotion and draws problems and aims to accumulate the basic materials for preparing guidelines of improving color environment at general classrooms of elementary schools. Consequently, according to color conditions, major colors on ceiling and wall were high brightness/nigh chroma of Y and YR line regardless of division of grades and other color factors of classroom showed that wall and ceiling used similar colors, but brightness was higher after change than before it. In evaluation of color images, lower grades showed negative color images such as 'common,' 'rustic,' and 'strange' before change, but they showed positive color images after change such as 'clean,' 'unique,' and 'soft'. But, most of higher grades showed negative reactions before change such as 'common,' 'strange,' and 'rustic' and they showed positive reactions after change only in such items as 'clean,' 'warm,' and 'unique', but Indicated negative reactions in remaining items such as 'strange,' 'rustic,' 'stiff,' and 'artificial'. Accordingly, in using colors for lower grade classroom, arrangement of colors through adjustment of brightness and chroma between ceiling, wall and other components based on coloring of high brightness and low chroma of similar colors should be considered and for higher grade classroom, arrangement of colors of unique images of mid-brightness/mid-chroma among warm color lines of similar colors should be examined.

Objectives: We investigated the isoflavone contained in SH003 and its fractions, and the effect of these components on the inhibition of breast cancer. Methods: The isoflavones in solvent fractions of SH003 extract were identified by UPLC-MS and its contents were quantified using HPLC analysis. The estrogenic activity of SH003 or fractions was assessed by ERE luciferase assay in estrogen receptor (ER)-positive MCF-7 cells. To test the breast cancer inhibitory effect, the cell viability was measured using an MTT assay. Results: In this study, we demonstrated that SH003 and fractions contain 4 isoflavones which are calycosin-7-β-D-glucoside, formononetin-7-β-D-glucoside, calycosin, and formononetin. Despite containing isoflavones, estrogen-dependent transcription activity was not altered by both SH003 and fractions. On the other hand, SH003 and fractions inhibited the cell viability of breast cancer. In addition, its isoflavone components also showed reduced cell viability in various breast cancer cells. Conclusions: Overall, the phytoestrogen included in SH003 and fractions did not influence the estrogenic activity, emphasizing the safety of SH003 and fractions in breast cancer treatment.

The purpose of this study is to calculate the size of unit space of the classroom in elementary school. The curriculum of Elementary school has changed since 1960. It has been reflected the architectural plan of classroom of the nationwide elementary school. However the Ministry of Education repealed the statute about the facilities of the schools on September in 1997 and the new education curriculum-the 7th curriculum-demands various activities in the classroom. So we need to another size of unit space of the classroom in elementary school because the size of unit space will affect the quality of education. This study represent that the size of unit plan is based on the size of human body, education curriculum, the number limit of classroom and teaching tools. It's generally known that a part of human body size has an invariable proportion with human's status. In this study, regression analysis is used to find out a part of the body-size of Korean. Through this analysis, status, age and weight remarkably relate with a part of human body-size. Then the size of unit plan of the classroom is calculated by the part of body-size and the type of desk arrangement.

A kindergarten requires an approach to meet the nature and sense of children who is main users. This study selected 33 private kindergartens which were located within a housing site development zone in Gwangju since the 1990's, had single use, and was constructed in the last five years. Also the image assessment according to types of color scheme was made. Then the factors which affected preference by type were analyzed and the basic of color scheme in a kindergarten classroom was provided. The following results were obtained. First, types of color scheme in a classroom included identity 12.1%, similarity 51.5%, and novelty 36.4% in harmony, but no contrast and achromatic color, Secondly, the assessment of preference according to each type was mostly positive. The highest preference was found in similarity harmony of warm color(e.g. YR, Y) and bright, clear, nice, and strong images were high in assessment. The lowest preference was found in identity harmony of cold color(e.g. GY). This color system had no clear image assessment, except manly or strong. In particular, warm color showed higher preference than cold color in similarity, novelty, and identity harmony. Thirdly, the factors affecting the preference of color scheme in a classroom most were ‘stable - unstable’, ‘clean - dirty’, ‘bright - dark’, ‘nice - not nice’, and ‘vital - dull’.
