The cultural contents are a field that originally has a cycle ranged from producers of various contents and distribution consumption. The various object elements composing of an ecosystem of cultural contents in this cycle, and the search of harmonious relations between these objects is becoming an important issue. The ecological approach on the cultural contents field is not being tried authentically until now, in spite of the expansion of interest and usefulness from its application at present, so there is no detailed discussion on the inside of an ecosystem and itsaction such as confirmation of object elements composing of the ecosystem, interaction principles between objects and object development, principles of co-evolution, etc. achieving common development of all objects composing of the ecosystem. Therefore, the present research aims to confirm object elements composing of the ecosystem of cultural contents through an ecosystem model that has been researched in several fields of the ecosystem and social science, and to seek interaction between objects and each object as well as a development direction of a total ecosystem.

The purpose of this research is to find factors that affect high school science teachers' class compositions. In this research, we developed the class composing factor analysis framework and we observed teachers' class to figure out the class composing factors. The results from this research were as follows: First, the class composing factor was classified with 'positive motive factor' and 'negative motive factor'. It is the positive motive factor that teachers' voluntary motives operate to teacher for class compositions. It is the negative motive factor that outer demands operate to teacher for class compositions. Second, both positive and negative motive factors were shown in all the steps, which included preparing a class, progressing a class, and after a class. Also, according to the circumstances, each factor changed. Minimizing and overcoming negative motive factors will lead to positive interaction between the teacher and students. It will also increase a teachers' achievements in class and maximize the effectiveness of class. Therefore, it is expected that this will be a great help for teachers to enhance their teaching professionalism.

Herbal medicinal interaction on the purgative action of Chungpesagan-tang, which is one of the traditional Korean medical prescriptions that has been most frequently used for stroke was investigated. Chungpesagan-tang had more potent purgative activity than Rhei Rhizoma alone. When each Chungpesagan-tang composing herbal medicine with Rhei Rhizoma was extracted with water, water extract of Raphani Semen with Rhei Rhizoma had the most potent purgative activity. However, Raphani Semen had not purgative activity. When Rhei Rhizoma with Raphani Semen was extracted, sennoside A content in the water extract was increased. The transformation of sennoside A of Rhei Rhizoma to rheinanthrone by human intestinal microflora was weakly induced by Raphani Semen. These results suggest that the purgative action of Chungpesagan-tang could be controlled by the addition and subtraction of Chungpesagan-tang-composing herbal medicines.

As a result of comparison analysis on body types of Korean women in their forties and Korean women residing in Japan, the following results had been found. 1. In terms of factors composing the body type, while women residing in Korea did not show large differences in obesity and horizontal size factors, women living in Japan showed higher contribution of obesity factor compared to horizontal size factor. That is, obesity factor was substantially more important among factors composing the body type for women residing in Japan. 2. Cluster analysis was done to understand the characteristics of body types and comparatively analyze them. Women residing in Korea were classified into tall and normal body, normal height with obese body, and short and chubby body. Women residing in Japan showed different characteristics with tall and obese body, tall and normal body with long lower part, and short and thin body. As a result of this study, identical ethnic group was found to take on different body types resulting from sociocultural differences and difference in eating habits if their place of residence differs for a long time.

Antioxidant effects of Rehmannia vaporata, Discorea Radix, Corni Fructus, Hoolen, Alismatis Radix, and Mountain Cortex Radicis composing Yukmijihwang-tang were studied. The results are as follows; 1. As a result of detecting the defensive effect of each component on cell damage, only the survival rate of cells with 10 ㎎/㎖ Mountain Cortex Radicis was significantly increased. 2. Next, we examined the inhibitory effects of them on ROS occurrence. The result showed significant inhibition of ROS occurrence in cells; with 10 ㎎/㎖ Rehmannia vaporata, cells with 10 ㎎/㎖ Corni Fructus, and cells with 10 ㎎/㎖ Mountain Cortex Radicis. Since the cells with 10 ㎎/㎖ Rehmannia vaporata, however, showed significant cypotoxicity, its result is not meaningful. 3. Finally, the investigation of ROS occurrence / cell found that Corni Fructus and Mountain Cortex Radicis had significant inhibitory effect on ROS occurrence.

For composing the structure model of national maritime power system by system structural modeling, in this study, the 50 basic factors are selected by survey of the extensive and through literatures on maritime, sea, maritime power and sea power. And the basic factors are classified into 36 component factors by cluster method. The 9 attributes are extracted by the application of the principle component analysis method, one of the factor analysis method in system engineering, to component factors. In this study, we define the attributes composing the national maritime power system by integrating the result of this study and existed our studies relating to this topic. Which are showed in Table 2. and we show the structure model of national maritime power system in Fig. 3. In Table 2, the 9 attributes are as follows : the fundamental power of maritime, shipping and port power, naval power, fishing power, shipbuilding power, the power of ocean research and development, dependency on seaborne trade, the protection power of ocean environment and the will and inclination of govemment. Also, in the case of evaluating this system, we conform the importance of considering the interactions among the attributes which have strong interactions in structure model of national maritime power system.

A study on Composing Unit Spaces of Apartment Houses according to the Differentiation in Lifestyle by survey on preferences. The purpose of this study is to propose composition models of unit spaces for 85m2 net area apartment houses by lifestyle types. This study set up a hypothesis that there is a critical divergence of preferences in composition types of unit spaces according to lifestyle. To prove the hypothesis, investigation on variable floor plans of apartments to extract spatial composition types of units and questionnaire survey on lifestyleand preferences for composition types were implemented. To extract several factors regarding, characteristics of lifestyle, factor analysis, was implemented for each variable. Cluster analysis was conducted to cluster interviewees by similarity of lifestyle. To identify and define how each factor reacts, ANOVA and cross tabulation analysis between factors and clusters were used. The type of spatial composition was analyzed by plane characteristic, spatial relation and spatial usability on the basis of apartment plate type. As a result, lifestyle was divided into three types: reasonable lifestyle, trend-seeking lifestyle and conservative lifestyle. As, the result of investigating characteristics for the type of spatial composition according to the type of lifestyle, preferred types and main districts were different. Therefore, the hypothesis was proved.
