The purpose of this study was to find out how sleep characteristics by Sasang constitution (SC) appear in Vietnamese immigrant women in Korea, and how sleep aberration by SC affected the quality of life. The number of 217 Vietnamese immigrant women joined this study. We surveyed SC with Korea Sasang Constitutional Diagnostic Questionnaire (KS-15) and sleep characteristics with Pittsburgh Sleep Quality Index(PSQI) questionnaire. We evaluated quality of life(QoL) with Euro Quality of Life-5Dimension(EQ 5D) questionnaire. A Chi-square test and a one-way ANOVA test were conducted according to SC, and T test also used to compare PSQI groups. Significant p was .05. The number(rate) of Taeeumin(TE), Soeumin(SE), and Soyangin(SY) were 40(18.4%), 55(25.3%), and 122(56.2%) respectively. The distribution of obstructive factors of sleep were significantly different according to SC(Too Cold in Sleeping, x =13.378, p=.037, Too Hot in Sleeping x²=12.834, p=.046). The distribution of daytime drowsiness(x²=15.379, p=.018) and falling concentration power (x²=17.533, p=.008) was significantly different according to SC. The sleep status of the subjects showed a significant negative correlation with the EQ 5D Visual Analogue Scale(VAS) (r =-.399, p<.001), and the EQ 5D Index (r=-.211, p=.002). In the EQ VAS, TE showed a difference between the good and bad sleeping groups (t=3.955, p<.001). SE showed a difference between the two groups in the EQ 5D Index (t=2.332, p=.037). SY did not show a difference between the two groups. This study reveals that sleeping is closely related with QoL and distribution of obstructive factors of sleep may be different according to SC. Further study to confirm the constitutional difference in race at Vietnam is needed.

Overall performance of the ground combat vehicle(GCV) system can be evaluated by the performance of subsystems regarding vulnerability, firepower, and mobility. Among them, vulnerability assessment is to find vulnerable areas by calculating the damage degree by the attack of an enemy weapon. Researches on the penetration damage have been done widely since 19th century. Many mathematical or empirical models for calculating the penetration depth were suggested for different targets and different warheads, which causes for a user to be confused. In order to solve this problem, this paper surveys on the warheads and the penetration models, and summarizes them into a table, and suggests the procedure to use the table, which helps a user to select the correct penetration model and calculate penetration depth faster. Two examples to calculate the penetration depth are presented to show the usefulness of the suggested method.

We intended to identify the health state of Oriental medical students and also to know how many things of health practice are in healthy group and non-healthy group classified by the THI average score, according to sasang constitution. We collected data with self-administered health questionnaires from 297 men and women, in 9 Korea oriental medical colleges. We diagnosed Sasang constitution using QSCCⅡ and also estimated health degree using THI. Non-healthy group practiced much more health behaviors than healthy one, and there were significant difference in Taeeumin and Soeumin. Non-healthy group of Taeeumin, Soeumin and Soyangin all practiced much more constitutional health behaviors than healthy one, and Soeumin non-healthy and healthy one all practiced much less health behaviors than Taeeumin and Soyangin group. Non-healthy group practiced health behavior for health care and maintenance more than healthy-one, and health state was related with sasang constitution health care. Therefore, institutional and systematic environmental condition would be needed in practicing healthy behaviors for improving the quality of health, and especially developed health promotion programs according to Sasang constitution too.

장은수(Eunsu Jang),박강(Kang Park) (사)한국CDE학회 2015 한국 CAD/CAM 학회 학술발표회 논문집 Vol.2015 No.하계

The purpose of this study is to determine the penetration component of Ground Combat Vehicle(GCV). by specific warhead as detail study for vulnerability assessment of UGV. Generally, checking of the penetrated component is determined to use penetration equation or impact analysis program. Complicated geometry, Application of new material, Visualization was required in order to check penetrated components of the GCV. So we analyzed the penetration process to using the impact analysis program(ANSYS Explicit STR code). ANSYS Explicit STR code is required for accurate analysis setting so as to get high accuracy of the analysis results. Therefore, we are developing How to increase the accuracy to use penetration experiment data according to variety case(Projectile/target combination). In this paper, we identify trends about the result of penetration analysis as base step of this study.

The solar energy is dramatically increasing as the alternative energy source and the silicon(Si) solar cell are used the most. In this study, the improved process and equipment for the metallurgical refinement of multicrystalline Si were evaluated for the inexpensive solar cell. The planar plane and columnar dendrite aheadof the liquid-solid interface position caused the superior segregation of impurities from the Si. The solidification rate and thermal gradient determined the shape of dendrite in solidified Si matrix solidified by the directional solidification(DS) method. To simulate this equipment, the commercial software, PROCAST, was used to solve the solidification rate and thermal gradient. Si was vertically solidified by the DS system with Stober process and up-graded metallurgical grade or metallurgical grade Si was used as the feedstock. The inductively coupled plasma mass spectrometry (ICP) was used to measure the concentration of impurities in the refined Si ingot. According to the result of ICP and simulation, the high thermal gradient between the two phases wasable to increase the solidification rate under the identical level of refinement. Also, the separating heating zone equipped with the melting and solidification zone was effective to maintain the high thermal gradient during the solidification.
