Physiological effects in SAM P6 and Rl by administration of Cervus cornu, Astragali Radix, Rehmanniae Radix, and Angelicae Radix extracts were screened to know in vivo activities of each extracts. We measured complete blood cells (CBC) such as aBC, HGB, and HCT using coulter's method. Plasma concentrations of albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea and total iron ere also analyzed using biochemical clinical autoanalyzer. Plasma concentrations of cortisol, total T$_3$, and total T$_4$ were measured by chemiluminescent immunoassay methods. At 12 weeks after birth, Cervus conu or Astragali Radix or Rehmanniae Radix extracts were given 5 g/Kg.day p.o. for 0,7,14,21, and 30 days each in both SAM Rl and SAM P6. Angelicae Radix study was done the same as the others except the mice were 16 weeks after birth. The RBC, HGB, and HCT levels after administration of Astragali and Rehmanniae were elevated in SAM Rl, but those in Cervi study were increased in SAM P6 the most. Decreases in alkaline phosphatase concentration of SAM Rl and P6 after Cervi administration were detected. Total plasma iron concentration was decreased by Angelicae administration in SAM P6. In general, Angelicae and Rehmanniae stimulate increases in cortisol, but total T$_3$ and T$_4$ levels were also elevated by all these extracts. In conclusion, these herval medicine extracts help hematopoiesis in SAMs through probably different mechanisms.

The properties of TiN as a barrier against Cu diffusion ere studied by sheet resistance measurement, X-ray diffraction, scanning electron microscopy, Auger electron spectroscopy, and capacitance-voltage(C-V) measurement. The sensitivities of the various methods were compared. Specimens with Cu/TiN/Ti/SiO2/Si structure were prepared by various deposition techniques and annealed at various temperatures ranging from $500^{\circ}C$ to $800^{\circ}C$ in 10%H2/90%Ar ambient for hours. As the effectiveness of the barrier property of TiN against Cu diffusion was vanished, the irregular-shaped sports were observed and outdiffused Si were detected on the surface of the Cu thin film. The C-V characteristics of the MOS capacitors varied drastically with annealing temperatures. In C-V measurement, the inversion capacitance decreased at annealing temperature range from $500^{\circ}C$ to $700^{\circ}C$ and increased remarkably at $800^{\circ}C$. These variations may be due to the Cu diffusion through TiN into $SiO_2$ and Si.

Two different quartz types of gasification reactor were used for pyrolysis and gasification of sawdust, ricestraw, ricehusk and municipal wastes which contain only cellulosics., operating at 1 atmospheric and vacuum pressure respectively. Also a stainless steel autoclave gasification reactor was used which is possible to use up to 100 atmospheric pressures and $800^{\circ}C$ of reaction temperature to complete pyrolysis and gasification reaction. The catalysts used in this reaction w- ere $K_2CO_3$, $Na_2CO_3$, Ni and Ni-$K_2CO_3$ as CO-Catalyst. The product gas mixtures were identified to be CO, $CO_2$, $C_3H_3$, $CH_4$ and $CH_3CHO$ etc. by Gas Chromatography and Mass Spectrometry. The pressurized gasification reaction shows significant increase in terms of methane composition and yield of product gases, comparing with those from unpressurized gasification reactions. The total volume of product gas mixtures amounts to 1600-1800ml per1gof waste of waste lignocellulosics or municipal waste, and the metane content of the gas mixtures reached to 40%, when $800^{\circ}C$ of reaction temperature and 100 atmospheric pressures with Ni-$K_2CO_3$ as CO-catalyst in the pressurized gasification reaction were used. This results show that the product gas mixtures containing 40% of methane call be used for alternative enegy source.

Background : Sasang Constitutional Medicine (SCM) is the field of traditional Korean medicine that emphasize four constitutional types for diagnosis and treatment. Appearance, personalities and pathological characteristics are main factors of Sasang constitutional classification. Previous studies carried out by the pulse analyzer showed that the pulse wave can discriminate these types. In addition, It was reported that the pulse wave are affected by age and sexuality. In this study, we investigated the pulse wave characteristics related Sasang constitution types in control group regarding their age and sexuality. Subjects and Method : Two hudred and eighteen volunteers participated in this study: healthy men in $20{\sim}49$ years old. Participants were interviewed and examined to evaluate their health condition and Sasang constitution type. Then they were tested with pulse analyzer when they ere stabilized. The pulse at the radial artery just beside styloid process was measured, because this area is landmark for pulse diagnosis in oriental medicine. 3-D Mac pulse analyzer (Daeyo Medi Co. Ansan. Korea) was used in this study. We analyzed main features of pulse waves with the Sasang condtitution types by the SPSS for Windows (ver 12.0). Results : There was significant difference between Taeum and other types in contact pressure as weil as in coefficient of floating and sinking pulse. Conclusion : By analyzing pulse waves of healthy adult men. we found significant differences exist between Taeum and other types. These pulse differences may characterize Taeum type, and it will be helpful for the evaluation of Taeum type.

Objectives: The purpose of our study was to evaluate the association between the intensity of physical activity (PA) and prevalence of cardiovascular disease (CVD) using Korean representative data. Methods: We analyzed 39 804 participant data from the Korea National Health and Nutrition Examination Survey, 2007-2013. Exposure variable was three levels of PA (low, medium, and high) in a week, and outcome variable was prevalence of CVD based on patient self-recognition and doctor's diagnosis. Complex logistic regression analysis was performed to evaluate the relationship between level of PA and CVD adjusted by body mass index, hypertension, hypercholesterolemia, diabetes mellitus, stress recognition, household income, smoking, and current drinking. The indices of association w ere estimated as crude prevalence odds ratio (POR), adjusted POR, and their 95% confidence interval (CI). All statistical analyzes were performed using complex sample analysis procedure of the SPSS version 23.0. Results: When all variables were adjusted, only high level PA in women showed a significant association with stroke (adjusted POR by patient's self-recognition, 0.57; 95% CI, 0.32 to 0.99, adjusted POR by doctor's diagnosis, 0.55; 95% CI, 0.34 to 0.87) and CVD (adjusted POR by doctor's diagnosis, 0.68; 95% CI, 0.48 to 0.96). Conclusions: High level PA in women has a significant reverse association with prevalence of stroke and CVD in Korea. Further study for elucidating the mechanism will be needed.

The ccpA gene encoding catabolite control protein A (CcpA) of Leuconostoc mesenteroides SYl, a strain isolated from kimchi, was cloned, sequenced, analyzed for transcript, and overexpressed in Escherichia coli. The ccpA ORF (open reading frame) is 1,011 bp in size, which can encode a protein of 336 amino acid residues with a molecular mass of 36,739 Da. The transcription start site was mapped at a position 49 nucleotides upstream of the start codon, and promoter sequences were also identified. The putative cre site overlapped with the -35 promoter sequence. The deduced amino acid sequence of the CcpA contained the helix-turn-helix motif found in many DNA-binding regulatory proteins. CcpA from 1. mesenteroides SY1 had $54.6\%$ identity with CcpA from Lactobacillus casei. The Northern blot experiment showed that ccpA was transcribed as a single 1.1 kb transcript, and transcription was repressed when grown on media containing glucose. CcpA was overproduced in E. coli BL21(DE3) cells using the pET expression vector, and purified to an apparent homogeneity. Gel Mobility Shift Assay with purified CcpA and a DNA fragment containing the ere sequence of the $\alpha$-galactosidase gene (aga) from L. mesenteroides SY1 revealed that CcpA bound specifically to the cre site of aga.

This study is about the cultural policy related to fine art under the U. S. Military Government in Korea(USAMGIK), from September 8, 1945, to August 15, 1948. Drawing on the previous studies of Korean art history in the 'Liberation Period', this study especially concentrates on intention, attitude and activities of the USAMGIK. Particularly the historical documents, stored at the National Archives at the College Park, Maryland, U.S.A., were valuable to do research on the cultural policy of USAMGIK. The cultural policy was subordinated to the political objectives of occupation that can be summarized to building a stronghold of anti-communism in South Korea. Under the U.S. Military government control, cultural matters were assigned to the Cultural Section, the Bureau of Education, which later turns into the Bureau of Culture, the Department of Education. The Bureau of Culture dealt with matters of the ancient Korean art treasures and of the Korean contemporary art. USAMGIK reopened the Korean National Museum which had been closed by the Japanese since the World War II period. After that, U.S. Department of State sent arts & monuments specialists to South Korea for investigating ancient Korean art and culture. Although some of the destructed art treasures were restored during the occupation, th ere were many negative cases including intentional destruction of historic sites or loot of art treasures by U.S. army. In contrast to their interest in the Korean antiquities, USAMGIK payed little attention to promoting the Korean contemporary artists and their arts. USAMGIK distrusted and suppressed the artists of leftism, while they kept good relations with the pro-American artists and the right-wing artists. In conclusion, the visual-cultural policy of USAMGK was mainly planned and carried out in order to preserve the national interest of the United States. This period produced long-term effects on the fine art and visual culture of South Korea, in terms of institution, policy, and reorganization of art community based on anti-cummunism.
