PURPOSE: This investigation in the study aimed to assess to determine proportion and susceptibility makers of sarcopenia in Korean younger female aged 30 to 39 years. METHODS: To address the complex sampling design of Korea National Health and Nutrition Examination Surveys, appropriate individual weights were incorporated into the analysis. The data employed a stratified, clustered, multistage probability sampling design. A total of 2,098 participants were enrolled and categorized into two groups based on their skeletal muscle mass index scores. One hundred and twenty-four individuals were placed in the sarcopenia group, while 2,024 were allocated to a normal group. The study examined various markers as variables, including age, height, weight, body mass index waist circumference, skeletal muscle mass index, systolic and diastolic blood pressure, fasting glucose, triglyceride, and total cholesterol levels, and smoking and drinking habits. RESULTS: The study found that proportion of sarcopenia in this population was 3.78% (CI: 2.89-4.94) in sarcopenia group and 96.22% (CI: 95.06-97.11) in normal with weighed values. Several susceptibilities including height, weight, BMI, waist circumference, diastolic blood pressure, and total cholesterol levels were risk factor for sarcopenia (p < .05), exhibited significant differences between the sarcopenia and normal groups. CONCLUSION: This investigation provides the proportion of sarcopenia and identifies relevant susceptibility markers among community dwelling younger women in Korea.

Objective: This study has been carried out to evaluation the effect of fertilization promoting peptide (FPP) on the kinematic parameters, capacitation and acrosome reaction of the frozen-thawed human spermatozoa. Methods: After FPP treatment, we examined kinematic parameters, capacitation and acrosome reaction, using the methods of computer-aided sperm analysis (CASA) and chlortetracycline (CTC) fluorescence analysis. Results: We have obtained the evidence that FPP can promote the capacitation and inhibit the spontaneous acrosome reaction of frozen-thawed human spermatozoa in vitro. FPP ($25{\sim}100$ nM) induced a significant increase in the proportion of B-pattem capacitated spermatozoa, and a significant decrease in the proportion of F-pattem uncapacitated ones without significant stimulation of acrosomal exocytosis. In the kinematic parameters treatment, FPP treated groups maint3ined higher LIN, BCF and STR than those of control. The VAP, VSL, VCL and ALH were not different. Therefore it is suggested that FPP in human seminal plasma may play a positive role in promoting human sperm function.

In order to obtain high proportion of Y sperm the semen was laid over 6%,10% and 20% bovine serum albumin. Separated sperm were stained with quinacrine mustard in order to see F - body which could be seen in human Y sperm. But we could'nt find F-body in the bull sperm. So sperm were compared with size of sperm head. As a result of observation separated sperm was small in size of length and width of sperm head as compared with control sperm. So it was found that the proportion of Y sperm showed a marked increase in separated layer. Then the higher albumin density was, the higher the proportion of Y sperm which had smaller head and faster motility was. But the higher albumin density was, the lower the recovery rate of sperm was. So it was hard to separate Y sperm in oligospermia.

This thesis aims at understanding Le Corbusier's architecture through study of proportion. Based on the analysis of these texts, four elements - geometry in the outline, diagonal regulation lines in the facade, arithmetic rhythm in the structure, composition in the inner space - were listed. Through these four proportional systems. ten houses of 1920's, designed by Le Corbusier were analysed. The Le Corbusier's proportional system can be classified by two different purposes ; aesthetics and utility standardization for the mass production was reflected. In the later period, the proportion system of 1920's has changed through the process of self-contradiction. But the concept of the golden section and the human scale was reflected on Modulor, which Le Corbusier created in 1940's. Therefore, Le Corbuiser's notion of proportion for harmony of architecture has consistent meaning throughout all of his works from the 1920's.

PURPOSE: This research investigated clinical hazardous components and analyzed the proportion of sarcopenia among young Korean women. METHODS: The cross-sectional study included 1,236 women aged 20 to 29 years, categorized into two groups according to their skeletal muscle mass index (SMI). Of these, 20 participants were placed in the sarcopenia group, while 1,216 were included in the normal group. The analysis involved hazardous components including body dimensions, clinical indicators, and behavioral trait variables: height, weight, body mass index, waist circumference, skeletal muscle mass index, systolic and diastolic blood pressure, blood laboratory tests assessing fasting glucose, triglycerides, total cholesterol, as well as smoking habits and alcohol consumption. Complex sampling analysis was used to analyze the proportion and hazardous components of sarcopenia. RESULTS: The proportion of sarcopenia was at 1.76% (95% of CI: 1.08-2.83). Anthropometric measurements, such as height, BMI, and WC, exhibited significant differences between the groups (p < .05). However, there was no significant difference in weight (p > .05) between the two groups. Among the clinical indicators, SBP, DBP, FBG, serum triglycerides, and total TC found to be significant hazardous components for sarcopenia within both groups (p < .05). Smoking status as a behavioral trait was significant as well (p < .05), unlike alcohol consumption (p > .05). CONCLUSION: This study discerned both the proportion of sarcopenia and the hazardous components associated with it among community-dwelling women of a young age.

Since the report in 1946 on the first isolation of Japanese encephalitis virus in Korea, the disease is known to occur every year and has occasionally spread in epidemic proportion among human populations. Because of its public health importance, it was deemed highly desirable to gain specific information as to natural history of the disease in Korea if we are to accomplish our ultimate objective of controling the disease in Korea. There still remain, however, unknown factors as to the ecology of Japanese encephalitis virus in Korea. This paper presents the results of serologic study on Korean cattle, hog and horse by means of hemagglutination inhibition (H.I.) test. The serum specimens were collected from Korean cattle, hog and horse their estimated ages being 3 to 9 years, 6 to 24 months and 2 to 14 years respectively, by jugular puncture; in Seoul and Kyung-Ki are a from the first part of May to November last, 1968. The strain used was designated by M 5/596. The methods of H.I. test employed in this study were essentially simillar to those employed by Clark and Fred. The results obtained summarized as follows; 1. Of samples of cattle sera tested, 183 (98%) was found to be positive, H.I. antibodies showing the highest proportion, on September. The lowest proportion showed 81 (68%) of 117 samples, on June. 2. One hundred and ninety-five and 114 swine serum samples tested were all of positive in both on September and October respectively. The lowest proportion showed 92 (29%) of 314 on June too. 3. Ninety (99%) of 91 equine serum samples tested contained demonstrable H.I. antibodies the highest proportion, on August. The lowest proportion was 19 (27%) of 70 samples on June. 4. Implications of these findings in the ecology of Japanese encephalitis Seoul and Kyung-Ki area were discussed.

Since the establishment of embryonic stem cell, pluripotency of the cells was known to allow differentiation of the cells into various cell types consisting whole body. Several protocols have been developed to induce expression of specific genes.. However, no precise protocol that will generate a single type of the cells from stem cells has been reported. In order to produce cells suitable for transplantion into brain of PD animal model, which arouse due to a progressive degeneration of dopaminergic neurons in midbrain, human embryonic stem cell (hESC, MB03) was transfected with cDNAs cording for tyrosine hydroxylase (TH). Successful transfection was confirmed by western immunoblotting. Newly transfected cell line (TH#2/MB03) was induced to differentiate by the two neurogenic factors retinoic acid (RA) and b-FGF. Exp. I) Upon differentiation using RA/ascorbic acid (AA), embryoid bodies (EB, for 4days) derived from hES cells were exposed to RA (10$^{-6}$ M)/AA (50 mM) for 4 days, and were allowed to differentiate in N2 medium for 7, 14, 21, or 28 days. Exp. II) When bFGF was used, neuronal precursor cells were selected for 8 days in N2 medium after EB formation. After selection, cells were expanded at the presence of bFGF (20 ng/ml) for another 6 days followed by a final differentiation in N2 medium for 7, 14, 21 or 28 days. By indirect immunocytochemical studies, proportion of cells expressing NF200 increased rapidly from 20% at 7 days to 70 % at 28 days in RA/AA-treated group, while those cells expressing NF160 decreased from 80% at 7 days to 10% at 28 days upon differentiation in N2 medium. However, in differentiation by RA/AA treatment system, there was a significant increase in proportion of neuron maturity (73%) at day 14 after N2 medium. TH#2/MB03 cells expressing TH are >90% when matured at the absence of either bDNF or TGF-$\alpha$. These results suggested that TH#2/MB03 cells could be differentiated in vitro into mature neurons by RA/AA.

This study investigated the effects of chitosan on cadmium(Cd) toxicity and mineral metabolism in rats exposed to cadmium by oral administration. Six week-old Sprague-Dawley rats were divided into eight groups. Four groups were fed AIN-93G based 3% ${\alpha}$-cellulose diets while the others were fed 3% chitosan diets for four weeks with oral administration of 0, 0.5, 1.0, 2.0 mg Cd/2ml distilled water three times a week, respectively. Cd contents in the serum, liver, kidney, testis and bone, and the excretion of cadmium in feces were determined. There was no significant difference in weight gain and food intake among groups. Cadmium contents in the serum, liver, kidney, testis, femur and lumbar were significantly increased in proportion to the administration level of Cd (p<0.05). A protective effect of chitosan on cadmium toxicity in tissue was shown only in the high level cadmium-intake group. The fecal excretion, absorption of Cd were increased by the administration levels of cadmium. These results suggest that Cd administration may facilitate the accumulation of Cd in the blood and tissue in proportion to the amount of administration, and also, that chitosan may be effective in lowering the accumulation of cadmium.

Monocytic cells in myeloid lineage are known for latent site of HCMV Previous studies have suggested that HCMV regulates cell cycle progression in a variety of cells, but studies in monocytic cells are limited. In this study, we attempted to understand cell cycle changes after HCMV infection in the monocytic cell lines. Flow cytometric analyses using propidium iodide revealed that the proportion of G0-G1 phase was increased and the proportion of S phase decreased in HCMV-infected THP-1 cells, but not in HL-60 cells. BrdU-incorporation assay supported that cell proliferation was inhibited in HCMV-infected THP-1 cells by inhibition of de novo DNA synthesis. Western blot analysis revealed that p21, inhibitor of cell cycle progression from G1 phase to S phase, was induced in HCMV-infected THP-1 cells but not in HL-60 cells. Thus, HCMV inhibited cell pro-liferation by arresting the cell cycle at G0-G1 phase through induction of p21 protein in promocytic THP-1 cells.
