Background/Aims: Westernization in many Asian countries have changed lifestyles and diets, so once rare diseases have now become prevalent. The aim of this study is to investigate the changing pattern of digestive and liver disease in Korea, from 1990 to 2006. Methods: We extracted data specific gastrointestina (GI) disease based on the International Classification of Diseases code from the in-patients records at the Kangnam St. Mary`s Hospital in 1990, 1996 and 2006. This hospital is a tertiary-care hospital in Seoul, Korea, which has a capacity of 800 beds. Results: The admission rate for GI disease increased between 1990 and 2006. Overall in-patients were 1,623 persons in 1990, 2,368 persons in 1996 and 4,166 persons in 2006. The mean age of in-patients increased as time went by. A stomach cancer was the most common diagnosis during all periods, but its prevalence has decreased. Colon cancer ranked the 7th in 1990, but markedly increased and now ranks the second. The third was a hepatocellular carcinoma. The bile duct and gallbladder cancer, pancreas and esophageal cancer ranking followed with little interval change. In cases of cancer patients, a regular admission dramatically increased for chemotherapy. The number of patients admitted with pre-malignant neoplasm of stomach and colon increased remarkably with the development of endoscopy. The liver transplant, inflammatory bowel discase, and reflux esophagitis emerged form mid-1990s with greater frequencies, yet much below the levels found in the West. The admission rate for peptic ulcer, especially ulcer bleeding remained relatively stable, despite a decreased rate for ulcer perforation. Liver cirrhosis, hepatitis, cholelithiasis with cholecystitis-cholangitis, appendicitis, hemorrhoid and gastritis all decreased. Conclusions: The stomach cancer is the leading cause of admission, despite a recent decline. Colon cancer showed a marked rise. The liver transplant, inflammatory bowel disease and reflux esophagitis were new diagnosis with an increased tendency.

The purpose of this study to investigated the effects of wrestling' weight loss on urine electrolyte (Na+, K+), Blood cell count, heart rate. Twenty one subjects participated in this study and reduced approximately 7% per body weight. The subject was divided short period weight reduction (n=6) during 7day, long period weight reduction (n=6) during 14day. Urine sample extracted 20 ml for electrolyte analysis from pre-, post body weight reduction, recovery(1day later). Similarly Blood cell count measured. For measuring heart rate, ubject performed anaerobic power test during 30 second, measuring immediately, 3, 6, 9. 15 minute' recovery period. The result following: Short terms weight reduction group showed no significant different in body composition (LBM and fat %) but long terms weight reduction group was significantly reduced lean body mass after weight reduction but did not change fat. The content of urine Na+ and K+ decreased significantly after body weight reduction in both group. In recovery period, urine K+ did not show any variation in both group. Urine Na+ returned to base line during recovery period in long term body weight reduction group, but these changes was not statistically significant. In conclusion, weight reduction of wrestling caused the change body composition, electrolyte and short terms weight reduction may detrimental effects body' homeostasis.

Objectives: To evaluate the acute toxic effects and approximate lethal dose of Cheonggan extracts (CGX) in SD rats and beagle dogs. Methods: Male and female rats were divided into 4 groups (Control, CGX 1250, CGX 2500, CGX 5000) respectively and male and female dogs were divided into two groups respectively (Control, CGX 5000) respectively. A single oral dose of CGX was treated to the rats and dogs. Mortality, signs of gross toxicity, and behavioral changes were observed over 14 days. All animals were observed every hour for 4 hours after administration and once a day thereafter for 14 days. Body weights were determined at $0_{th}$, $7_{th}$, and $14_{th}$ days. All surviving animals were sacrificed and necrotized. Major organs were inspected visually for gross findings. Results: No animals died in any of the groups during the experimental period (2 weeks), rats or dogs. Body weights of rats and dogs during the experiment continuously increased in all groups but there was no significant change. No abnormal clinical signs were observed for 2 weeks after a single administration of CGX in any dose group of CGX, rats or dogs. No abnormal findings in major organs were observed in any group of rats or dogs. Conclusion: CGX does not have acute toxic effects in rats or dogs. Therefore, an approximate lethal dose is assumed to exceed 5000 mg/kg in both rats and dogs.

디자인은 섬유패션 산업에서 제품의 경쟁력을 결정짓는 핵심요인이다. 무단복제를 방지하고 독창성을 확인하기 위하여 제시된 디자인의 유사도를 측정하는 것은 매우 중요하다. 본 연구에서는 딥러닝 기법을 이용하여 섬유 디자인의 이미지로 부터 특징(feature)을 수치화하고, 스피어만 상관계수를 이용하여 유사도를 측정하였다. 유사한 샘플이 실제로 검출되는지 검증하기 위하여 300장의 이미지를 임의로 회전 및 색상을 변경하였다. 유사도 수치가 높은 순으로 Top-3와 Top-5의 결과에 회전을 하거나 색상을 변경한 샘플이 존재하는지 측정하였다. 그 결과, AlexNet 보다 VGG-16 모델이 월등히 높은 성능을 기록하였다. VGG-16 모델의 성능은 회전 이미지의 경우에 유사도 결과값이 높은 Top-3와 Top-5에서 64%, 73.67%로 가장 높게 나타났다. 색상변경의 경우에는 Top-3와 Top-5에서 각각 86.33%, 90%로 가장 높게 나타났다. Design is a key factor that determines the competitiveness of products in the textile and fashion industry. It is very important to measure the similarity of the proposed design in order to prevent unauthorized copying and to confirm the originality. In this study, a deep learning technique was used to quantify features from images of textile designs, and similarity was measured using Spearman correlation coefficients. To verify that similar samples were actually detected, 300 images were randomly rotated and color changed. The results of Top-3 and Top-5 in the order of similarity value were measured to see if samples that rotated or changed color were detected. As a result, the VGG-16 model recorded significantly higher performance than did AlexNet. The performance of the VGG-16 model was the highest at 64% and 73.67% in the Top-3 and Top-5, where similarity results were high in the case of the rotated image. appear. In the case of color change, the highest in Top-3 and Top-5 at 86.33% and 90%, respectively.

<P><B>Abstract</B></P> <P>Refrigerants have been continuously developed to improve their thermal performances and to deal with relevant environmental issues. Recently, regulations on refrigerants are being intensified due to the global warming. To meet the enhanced environmental standards, low global warming potential (GWP) refrigerants have been developed. In this study, experimental studies are conducted to investigate the characteristics of condensation heat transfer and frictional pressure drop for R-1233zd(E). The experiments are carried out under partial condensation conditions in a plate heat exchanger to measure temperature, pressure and mass flow rate. Heat transfer coefficients and frictional pressure drops with respect to mean vapor qualities are yielded. During the partial condensation process, the heat transfer coefficients increases as the mass and heat fluxes increase. However, no significant change in frictional pressure drop is observed when the heat flux changes. It is concluded that other correlations for Nusselt number and pressure drop from the literature cannot be applied for the low GWP refrigerant, R-1233zd(E), and the present experimental correlations agree well with the experimental results with the error bands of ±20%.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The condensation heat transfer and pressure drop in PHE with R-1233zd(E) are experimentally tested. </LI> <LI> No significant change in frictional pressure drop is observed when the heat flux changes. </LI> <LI> The present experimental correlations agree well with the experimental results with the error bands of ±20%. </LI> <LI> Other correlations from the literature cannot be applied for the low GWP refrigerant, R-1233zd(E). </LI> </UL> </P>

Public service facilities are essential elements to improve the quality of urban life. Among public service facilities, noxious facilities related to environmental problems have a lot of difficulties in finding their locations and being supplied properly. NIMBYS(Not In My Back Yard Syndrome) indicates these problems. Accordingly, the purpose of this study is to find the problems involved in the lacations of sewage treatment plants, on of noxious facilities, and to suggest alternative plants. The results of the analysis are the followings : First, sewage treatment plants in sample regions are lacated in proper zones. That is, most of them are located in greenbelts and the cities with many industrial functions have the plants located in industry zones. Second, sewage treatment plants stand in outer regions of the city far from the commercial zone and public institutions-the city hall, medical institutions. Third, the Multiple Regression Analysis shows the explanatory variables influencing the decision on the locations of plants INDI, CIDI, RODI and AREA. The result of this analysis has a meaning. The model location of a sewage treatment plant is as follows. FACI = C + 15.40217 * INDI + 4.90597 * CIDI + 12.58442 * RODI - 0.79780 * AREA FACI : location coordinates of the sewage treatment plant
