The purpose of this study is to analyze the body type of children's, especially torso, and to provide the fundamental data for children's clothing construction which can reflect the characteristics of their bodies. The subjects for photographic measurements are 308 elementary school children aged from 6 to 8 living in Seoul and urban area. Anthropometric measurements were performed indirectly from the pictures of subjects. The data were analyzed statistically using SPSSWIN. The results obtained from this study are as follows: 1. Through one-way ANOVA, items for heights, breaths, weight reveals the significant differences according to ages and genders. 2. Through Pearson correlation, it turns out that there are high correlation between any items of heights, but there is no correlation for item of shoulder inclination with any other items. 3. Through factor analysis of principal component model, six factors were extracted which covers 83.6% of the whole information. The first factor represents the items of heights which relates with linearity. The second factor describes the items of breaths, depths, and weight in relation with laterality. The third factor were gathered with depths of front and back in relation with posture of side, which proves as important one to characterize the children's torso. The other factors represents the items of posture of neck, depths in neck, shoulder inclination, respectively. 4.

CS-2l lymphoma cells that preferentially metastasize to lymph nodes after s.c. inoculation into BALB/c mice were grown in vitro in the presence of CA- 12 stromal cells isolated from lymph nodes. In order to obtain fundamental data on the identification and characterization of the soluble factors produced by CA-12 stromal cells, the conditioned medium of CA-12 stromal cells that inhibited apoptosis of CS-21 cells was examined. Various analytical treatments revealed that the soluble factors in CA-12 conditioned medium are very sensitive to heat treatment and trypsinization. Moreover CA-12 conditioned medium has an affinity with heparin but not with Con-A. In addition to these, the activity of CA-12 conditioned medium was blocked by H-7, a PKC inhibitor, but the conditioned medium could not induce the differentiation of thymocytes. We concluded that CA-12 conditioned medium contains stromal cell-derived apoptosis-inhibitory molecules that play an important role in proliferation of CS-2l cells by suppressing cell apoptosis.

When surveying the cultural heritages especially in the case of stone structures, preserving their original state is of primary importance. For the effective assessment of survey results of stone structure, the dynamic characteristics of that system should be considered. Dynamic characteristics of stone masonry structures depend on several factors such as coefficients of friction, contact conditions, and number of layers of bonding stones. These factors can be estimated by using the dynamic analysis results. This paper describes a method for natural frequency determination of traditional stone arch bridge subjected to compressive force. For this purpose, multi-layered granite brick models of for arch bridge were made and fundamental frequencies corresponding increasing axial forces were measured.

Spinning process is a chipless metal forming method for axi-symmetric parts, which is more economical, efficient and versatile method for producing parts than the other sheet metal forming process such as stamping or deep drawing. In this study, a fundamental experiment was conducted to improve productivity with process parameters such as tool path, angle of roller holder($\alpha$), feed rate($\gamma$) and corner radius of forming roller(Rr). These factors were selected as variables in the experiment because they were most likely expected to hale an effect on spring back. The empirical results were analyzed to know how much spring back was affected by these factors. And also thickness and diameter distribution of a multistage cup obtained by spinning process were observed and compared with those of a commercial product produced by conventional deep drawing.
