Every construction company should consider the apartment price when building apartment houses because the sales price has a great impact on the rate of apartment sales. Here, the average apartment price and characteristics of an apartment complex are factors that determine the sales price. However, the existing apartment pricing method fails to properly reflect the weight of each factor. Therefore, the study investigates factors that impact the apartment price and importance of each factor. It examines the apartment pricing method taking into account of the weight.

This Paper presents a robust design of an Electrorheological(ER) damper using Taguchi method. Taguchi method is a robust design method that determines control parameters in the presence of noise effect. Electrode length, electrode gap, base oil viscosity and the weight ratio of ER particles are chosen for the control parameters and the temperature is considered to be a noise factor. The sensitivity of each factor with signal-to-noise(S/N) ratio and analysis of variance are investigated. The analysis results show that the electrode length and base oil viscosity of the ER fluid mostly affect the damping force in the absence of electric field. On the other hand, when the voltage is applied to the ER damper, the electrode length and the weight ratio of ER fluid exhibit significant effect. Based on the Taguchi method, an optimal configuration was designed and the robustness of the designed ER damper was validated by comparing the analysis and experimental results.

In this study, we analyzed the structural safety and vibration characteristics of rotational drive in 3D CT scan equipment using finite element analysis. The analysis results showed a safety factor of 9.2 and a left and right vertical deflectional deviation of 0.24mm from the maximum equivalent stress. After applying weight compensation of 27.7kgf, the structural analysis reduced the safety factor to 7.6, but the deflectional deviation of the left and right structure was reduced to 0mm. Also, we presented the optimum design of rotational drive through the vibration analysis.

The purpose of this study was conducted to make a comparative biomechanical analysis of X-factor and X-factor stretch during driver and iron swing. The subjects were composed of 10 professional golfers with more than 10 years career. The result was as follows: First, the analysis of the back swing with driver and iron swing showed no differences statistically between both the timing in horizontal rotating of shoulder and hip, the time required for X-factor stretch also showed no differences statistically. Second, the back swing with a driver swing showed more maximum horizontal rotation of shoulder and hip joint than the back swing with an iron swing, but the twist of shoulder and hip that was X-factor stretch angle showed no difference. Third, the GRF of the max value for the left and right foot during shoulder and hip horizontal rotation of back swing showed no differences statistically in the movement of driver and iron swing during the back swing, and the GRF of X-factor stretch for the left and right foot showed no differences statistically in driver and iron swing. Therefore the result of this research showed that the operation of torso(X-factor stretch) and weight shifting were similar although the horizontal rotation of body was different during the driver and iron swing.

Purpose : This study was carried out to investigate the effects of Gagamdokhwalgisang-Tang on the morphometric changes of femur, and on the hormones and cytokines associated with bone metabolism in overiectomized rats. Methods : Twenty-four female Sprague-Dawley rats were divided into sham operated group(normal) ovariectomized group(control), and treated with extract of GD group(treated). Each group was evaluated the changes of body weight at 0, 3, 6, 8 weeks after ovariectomy. Morphometric analysis(femur weight, femur/body weight ratio, femur ash weight femur ash/body weight ratio cross sectional area of compact bone and concellous bone of femur) and histopathological examination were performed at 8 weeks after ovariectomy. Estrogen, Alkaline Phosphatase(ALP) and cytokine(Tumor necrosis $factor-{\alpha}$, $Interleukin-l{\beta}$, Inerleukin-6) assay were performed at 8 weeks after ovariectomy. Results : 1. The body weight of control and treated group was significantly increased(p<<0.001) compared with the normal group at 8 weeks. 2. The femur weight and femur/body weight ratio of treated group were significantly increased(p<<0.05, p<<0.01) compared with the control group at 8 weeks. 3. The femur ash weight showed no significantly different changes, but femur ash/body weight ratio of treated group was significantly increased(p<<0.05) compared with the control group at 8 weeks. 4. In the cross sectional area of cancellous bone of femoral body, the treated group was significantly increased(p<<0.001) compared with the control group at 8 weeks. 5. The serum estrogen level of treated group showed no significantly different changes compared with the control group at 8 weeks. 6. The serum ALP activity of treated group was significantly decreased(p<<0.01) compared with the control group at 8 weeks. 7. The serum Tumor necrosis $factor-{\alpha}(TNF-{\alpha})$ level of treated group was significantly decreased(p<<0.05) compared with the control group at 8 weeks. 8. The serum $Interleukin-l{\beta}(IL-1{\beta})$ level of treated group was significantly decreased(n<<0.001) compared with the control group at 8 weeks. 9. The serum Interleukin-6(IL-6) level of treated group was significantly decreased(P<<0.01)compared with the control group at 8 weeks. Conclusion : These results indicate that GD inhibits bone resorption in ovariectomized rats. And the major inhibitory mechanism may be related to the inhibitory effects of GD on the secretion of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 in the pathogenesis of osteoporosis in estrogen deficient rats.

The purpose of this research is to study the recognition of real somatotype and body of college women. The study was carried out by classifying somatotypes into three categories based on the body index; slim, normal, and obese somatotype. The subject of this study was 106 college women, and real measurement and survey were used. Data was analyzed by SPSS 12.0 and cross tabulation analysis, t-test, Anova, and correlation analysis were operated. The result is as follows. 1. The height of the subjects was 163.5cm, weight was 53.3kg, Rohrer index was 1.2, BMI was 19.9, Vervaeck index was 84.4 and the classification based on the body index belonged to the normal group. 2. The characteristics of groups divided by the body index are that slimmer groups is longer in length factor and smaller in the factors related with volume than other groups. The characteristics of groups classified by self-consciousness shows significant difference in all girth factors, back intersyce breadth, front intersyce breadth, neck to nipple length, and nipple to nipple breadth. 3. Conscious about the somatotype with using body index generally shows similarity. In the length factor including height, slim somatotype group is perceived as longer than normal somatotype group, and in the girth factor including weight, normal somatotype group is recognized as bigger and thicker than others.
