Vitamin D and carotid subclinical atherosclerosis in SLE Chang-Bum Bae, Ju-Yang Jung, Bo-ram Go, Hyun-Ah Kim, Chang-Hee Suh Department of Rheumatology, Ajou University School of Medicine, Suwon, Korea Introduction Atherosclerosis develops earlier in systemic lupus erythematosus (SLE) and is the important cause of mortality. It has been suggested that vitamin D deficiency contributed cardiovascular disease and immune dysregulation in SLE. Methods One-hundred two female patients with SLE and 52 normal controls (NC) were recruited. The carotid artery intima-media thickness (cIMT) and plague were assessed by B-mode ultrasound at the carotid artery level. Vitamin 25(OH)D3 levels were checked by immunoradiometric assay using the Bio-Line 25(OH)D3-Ria CT kit (Bio-Line S.A., Belgium). Disease activity markers were checked at the time of enrollment. Results The cIMT of SLE is 0.41±0.08mm, which is higher than NC (0.37±0.11 mm, p=0.012). Also, carotid artery plague index (PI) of SLE is higher than NC (0.68±1.39 vs 0.26±0.87, p=0.026). The cIMT was correlated with age (r=0.442, p<0.001), body mass index (r=0.246, p=0.013), waist-hip ratio (r=0.245, p=0.013), SLE disease activity index (r=0.239, p=0.016), taking aspirin (r=0.244, p=0.013), and the carotid artery PI was correlated with renal involvement (r=0.224, p=0.023) in patients with SLE. Vitamin 25(OH)D3 was not showed correlation with cIMT and carotid artery PI. Also, it was not correlated with disease activity markers. Conclusion In patients with SLE, the risk of cardiovascular disease measured by cIMT and carotid artery plaque was higher than NC, which may be derived from systemic inflammation. However, vitamin D levels were not showed significant correlations with carotid subclinical atherosclerosis. It may be not suitable to assess vitamin D as marker of disease activity or subclinical atherosclerosis.

본 논문에서는 기존의 세탁조와 전동기 사이 기계적인 기어 및 벨트를 이용하여 전동기의 토크를 전달해 세탁하는 간접 구동방식이 아닌 세탁기의 저소음화를 위한 기어 및 벨트를 제거한 직접 구동방식의 외전형 SRM을 설계하였다. 세탁기에서 저속 고토크 특성을 가지는 세탁모드와 고속 저토크인 탈수모드를 모두 만족하는 넓은 가변속 범위 특성을 가지는 외전형 SRM을 설계하고 FEM 특성을 해석하였으며, 제안된 12/8 외전형 SRM이 드럼세탁기의 직접 구동 전동기로 사용될 수 있는 가능성을 확인하였다.

The discharge of papermill wastewater has been continuously increased from 512,000 ㎥/day in 1987 to 735,000 ㎥/day in 1994. The method used for treating this type of industrial wastewater has been an activated sludge process, which may be the most effective and widely used form of biological wastewater treatment, but this method causes some operational problems when it is applied for treating a papermill wastewater: i. e.) 1) activated sludge processes are efficient for reducing BOD removal but are not effective in reducing COD level due to a higher fraction of NBDCOD caused mainly by celluloses and lignins, 2) the extra sludge production is too much. It is known that lignins can be soundly degraded by Phanerochaete chrysosporium called "a white rot fungi". Treating papermill wastewater using an immobilized Phanerochaete chrysosporium would give some relative benefits: 1) it can reduce a significant fraction of NBDCOD of the papermill wastewater, 2) the sludge production can be reduced. The results of this study can be used to provide not only new and innovative design parameters for prototype treatment process but also to renovate the existing treatment facilities. The results of this study are follows; 1) Nutrient(P) injection had no significant effect on the removal efficiency. 2) The operational condition that could keep the national discharge limit of effluent("Na" zone, less than COD_Mn 90㎎/ℓ and less than BOD_5 80㎎/ℓ) was about 0.33㎏-BOD_5/㎥·day or less, and was required for the same limit more than 8 hours of hydraulic time. 3) The sludge produced from treating one cubic meter of papermill wastewater was about 0.001 ∼ 0.06 ㎏/㎥, which is much less than the amount of activated sludge produced.

This study was conducted in order to investigate removal efficiency of turbidity, organic matter, nitrogen and phosphorus to reduce environmental pollution of treatment livestock wastewater with mixed proportion of loess and lime. The result of study, the removal of turbidity, COD_Cr and T-P increased along the dosage, and was to be fixed above the appropriate dosage. In the removal turbidity, the appropriate mixed proportion of loess and lime was Loess:Lime = 3:7, the appropriate dosage was 30g. In the removal COD_Cr, T-P and TKN was Loess:Lime = 3:7, 30g, Loess:Lime = 5:5, 20g, Loess:Lime = 5:5, 40g, respectively.

A cytochrome C - specific protein methylase Ⅲ was purified approximately 63 - fold from Saccharomyces cerevisiae. The unmethylated cytochrome C served as substrate for the enzyme. Horse heart apocytochrome C was found to be a better substrate than the native horse heart cytochrome C. This observation suggests that the in vivo methylation of cytochrome C in the yeast probably occurs before cytochrome C become attached to the mitochondria. In partly purified protein methylase Ⅲ the optimun pH is about 9.0, the enzyme activity is linearly proportional to the amount of enzyme protein up to about 30㎍ and also to time up to 15min. The Km values for horse heart cytochrome C and S - adenosyl - L- methionine were 1.33mM and 40㎛, respectively. S - adenosyl - L - homocysteine was found to be a competitive inhibitor for S - adenosyl - L - methionine, and the Ki value was 2.7 μM. The molecular weight of the enzyme was approximately 97,000, determined on sephadex S- 200 gel filtration. The regulation of cellular cytochrome C and the protein methylase Ⅲ are not coordinately related in a parallel manner.

A numerical model for the prediction of runway(road) temperature and ice has been tested on data from Susack. The model is based on the solution of the equation of heat conduction in the ground and the surface energy-balance equation. Sensitivity experiments have been carried out in order to assess the relative importane of the various active processes. It is importannt to specify a realistic temperature and cloud structure in the lower part of the atmosphere. The best results were obtained with a detailed temperature and humidity analysis using significant points in the applied radiosonde data. Some further improvement was obtaind with a simple capable of adjusting the initial atmospheric tmeparature profile for analysis bias. The results indicate that the model can be used for high-quality road temperature forecasts up to a range of at least 3h.

Purpose: Recently there are scientific evidences for the health effects of Asian dust-storms. Particularly in 2002, the daily average of PM_(10) exceeded 600 and 700 ㎍/㎥ in March and April respectively. We examined the effects of Asian dust-storms on perceived symptoms and preventive behaviors among children, adults, and elders. Method: The subjects of this study were 425 children, 444 adults and 60 elders. A questionnaire survey was carried out on the children and the adults by teachers and on the elders by interviewers to obtain information on demographic variables, perceived symptoms and preventive behaviors, previous respiratory disease, environmental tobacco smoke, and proximity between the house and the road during Asian dust-storms. We analyzed using descriptive statistics, X_(2) test and multiple logistic regression models. After adjustment for potential confounders, we estimated the odds ratios and 95% confidence intervals of the children and the elders for perceived symptoms and preventive behaviors. Result: The elders had a significantly higher prevalence of respiratory symptoms than the other groups. The children had a significantly higher prevalence than the adults in getting URI (1.51), coughing (1.68), rhinorrhea (1.46), fever (2.39) and medication for allergy or asthma (1.90). The children had better behaviors than the elders in closing windows (3.57), taking less outdoor recreational activity (2.59) and staying home (2.60).

The purpose of this study is to analyze the preference of tailored jacket according to the body type and the degree of satisfaction with the body of middle-aged women. The subjects were 323 middle-aged women ranging from 35 to 50 years old. We measured their bodies and asked them to report to the questionnaire. The results are as follows. There was a significant difference in the preference of tailored jacket according to the body type of middle-aged women. The women of the type 1 preferred X silhouette and the women of the type 2, A silhouette. The women of the type 3 preferred H silhouette, and the women of the type 4, H silhouette. There was a meaningful difference in the preference of tailored jacket according to the degree of satisfaction with their bodies. As satisfied with the girth of the body, weight, and figure they recognized X silhouette attractive, graceful, active, and soft.
