This thesis aims to analyze the visual perceptual effects drawn by 'axial composition and divergence' and to interpret the architecture of Kahn in respect of 'axial composition and divergence'. Axial composition of the form, the location of the entrance and divergence of internal movement were checked up about 53 works by extracting parti which is basic element of spatial composition. The 3D modeling simulation was performed for the selected 10 works in order to analyze the visual perceptual effect due to divergence of the internal movement. The reaction of the observer's actions and visual perception by 'axial composition and divergence' is presented in the following steps. 1. Divergence of the entrance/a panorama of expanding planes. 2. Divergence of internal movement/The process of perception of visual rotation and central spatial form. 'Perceptive form' created by 'divergence' is the result of diverse and flexible series of processes which must be experienced in person in order to reach the space as a room with a definite domain and center.

Effect of bombardment of the growing film by energetic particles on its properties is know over many years and is widely used for modification of the film properties. Despite of this there are no final answers on such questions as: what is the mechanism of compositional changes that take place for some compound films deposited under the ion bombardment, how the ion bombardment influences the epitaxial growth, what mechanisms govern the growth of the film on its early stages during deposition under the ion bombardment. The role of composition of film-forming species in formation of film structure is barely investigated or even not investigated at all. Experimental evidence and discussion of the influence of ion bombardment and composition of film-forming species on structure and composition of compound films are briefly considered in the review.

Under the condition of Baader aging, the chemical composition variation and the influence of transformer oil aging on electrical properties such as dielectric loss factor and physic-chemical properties such as interfacial tension were studied in the aging precess. Moreover, the correlation between hydrogenated transformer oil electrical and physic-chemical properties and its chemical composition variation were also investigated. The results show that these parameters of physic-chemical and electrical properties of hydrogenated transformer oil relate to each other and have closed correlation with chemical composition.

A vitrification process is under development in KEPRI for the treatment of low-and medium-level radioactive waste. Although the project is for developing and building Vitrification Pilot Plant in Korea, one of KEPRI's concerns is the quality control of the vitrified glass. This paper discusses a methodology for the estimation of glass composition by on-line measurement of molten glass properties, which could be applied to the plant for real-time quality control of the glass product. By remotely measuring viscosity and density of the molten glass, the glass characteristics such as composition can be estimated and eventually controlled. For this purpose, using the database of glass composition vs. physical properties in isothermal three-component system of SiO$_2$-Na$_2$O-B$_2$O$_3$, a software TERNARY has been developed which determines the glass composition by using two known physical properties(e.g. density and viscosity).

This study was intended to grasp the research trends related to the spatial composition of nursing homes. The 43 research papers were collected and analyzed. They were analyzed to focus on the research methodology and research contents related to the spatial composition of nursing home. The researches on spatial composition of nursing home were categorized into 5 types ; 1) the researches on the overall spatial composition of nursing homes, 2) the ones on space planning of each room in nursing homes, 3) the ones on the space size of nursing home, 4) the ones on the spatial composition of nursing homes in foreign countries, 5) the ones on the usage conversion of small-sized hospital and closed school into nursing home. The size and layout of a bedroom and common space were the main issue. These studies have been consistently carried out since late 1990 and many researches used the method of the analysis of floor plan and the field study. However, the number of the subject nursing homes and the categorized space areas were different depending on studies. Therefore, it was difficult to synthesize these various results. In order to compare and synthesizing the various results of these many studies, the same criteria for dividing the spaces of nursing home needs to be applied. However, many results from these researches related to the space composition of nursing home would be the useful data for planning the nursing home.

Mn-Zn 페라이트 단결정 성장시 일반적인 Bridgman법에서 조성변동 문제가 발생한다. 상평형도를 이용하여 원료 조성을 A, B로 분리하여 조성 B 원료를 단결정 성장 속도와 동일하게 투입함으로써 조성변동 문제를 해결하였다. 실험변수를 바탕으로 A조성을 52 mol% $Fe_2O_3$, 30 mol% MnO, 18 mol% ZnO로 선정하였고, 원하는 단결정 조성인 B 조성을 53 mol% $Fe_2O_3$, 28.5 mol% MnO, 18.5 mol% ZnO로 선정하여 직경 60mm, 길이 300mm 단결정을 성장시켰다. 성장된 단결정은 조성 B 원료 정제가 투입된 30~270mm 부위에서 조성 변도 없이 균일하게 B 조성과 비슷한 조성을 가졌으며, 이에 따라 주파수 5 MHz에서의 투자율값도 균일하게 600 근처로 높게 나타났다.

Objectives : The purpose of this study was to evaluate the body shape of Sasang Constitutions by body composition and body measurement. Methods : This study was carried out 98 cases(68 males and 30 females)of Oriental Medical College at Kyunghee University. After determining the Sasang Constitutions(Soeumin, Soyangin, Taeumin) by QSCCII, the body shape of each group were analysed by body composition(INBODY 2.0, Biospace, seoul, korea) and body measurement. Results : 1) The result of Sasang Constitution analysis of 98 cases were classified as Soumin(52%), Soyang(24.5%), Taeumin(23.5%). 2) In the body composition and body measurement, there were significant difference from intercellular fluid, protein, mineral mass, weight, percent body fat, body water of left arm and BMI between Taeumin, Soyangin and Soumin. 3) In the body composition of male, Taeumin group showed that the arms were more developed than the legs and the upper trunk were more developed than the lower trunk. Soumin group showed the asymmetry of the right and left limbs. Soyang group showed the asymmetry of the right and left arms. In the body composition of female, Taeumin group showed the asymmetry of the right and left upper limbs. Conclusion : There are significant relationships between Sasang Constitutions, Body composition and BMI. The findings indicated here Body composition could be useful mean to make a diagnosis of the body shape, body type, physical constitution of Sasang constitutions.

In this paper we designed a service composition architecture which enables the functional extension of existing service or the creation of new service by combining more than one service. The designed composition architecture is based on the service architecture of the TINA-C. It is designed by extending TINA information model and computational model. Composition related object, relations and interface between objects are defined in the information model and the computational model. And we tested the designed architecture by implementing two multimedia service and composition the services.
