The data gathered from 760 visitors in 30 museums were analyzed by the regression analysis and path analysis.The results of analysis indicated that, 1) museum fatigue was more likely to be affected by mental fatigue rather than physical one. mental fatigue had

This work experimentally investigates DME-Diesel blended fuel influences combustion characteristics and emissions(NOx, CO, HC, Smoke) in a single-cylinder DI diesel engine. The volume ratios for DME and diesel are 5:95 and 10:90 respectively and the both ratios have been used altogether in blended fuel. DME as an alternative fuel has been actively discussed for clean combustion and low exhaust emission in a compression ignition engine. DME is possible to operate by diesel cycle in a compression

Purpose: Low quality research can have an error drawing result and it can be distored. Thus, quality assessment is required for appropriate clinical application of the results of studies using randomized controlled trial (RCT). Materials and Methods: A quality assessment was conducted on the articles of Prostate published in Republic of Korea, using typical tools of RCT quality analysis such as Jadad scale, van tulder scale, and Cochrane collaboration risk of bias Tool (CCRBT). Results: The firs

목적: 이 연구에서는 백선에 의한 급성 간염의 임상양상과 치료 경과 및 합병증에 대하여 알아보고자 하였다. 방법: 2004년 1월부터 2009년 7월까지 백선에 의한 독성간염으로 입원치료를 받은 28명을 대상으로 하였다. 모든 환자는 RUCAM 점수가 6점 이상이었다. 대상 환자에 대하여 복부 전산화단층촬영을 시행하였고, A형, B형, C형 간염에 대한 표지자 검사를 시행하였다. 임상경과에 따라서 CMV, EBV항체를 조사하였으며, 추가로 자가면역 질환이 의심되는 경우에는 항핵항체, 항미토콘드리아 항체, 항평활근 항체를 검사하였고, 양성인 경우는 제외하였다. 결과: 평균나이는 53.0±11.0세였다. 남녀 비는 10:18이었고, 체질량 지수(BMI)는 23.4±2.7이었다. 내원 시의 주증상은 황달이 19예, 피로감 16예, 오심 12예, 식욕부진 12예, 복통 7예였고, 백선의 평균 복용기간은 24일이었다. 검사실 소견으로는 백혈구 6,673±1,769/mm3, 혈색소 13.6±1

Objectives: The purposes of this study were to evaluate the prevalence of epilepsy and to estimate the cost of epilepsy in Korea, 2010. Methods: This study used a prevalence based approach to calculate the cost of epilepsy. Claims data from the Korean national health insurance and data from the Korea health panel, the Korea National Statistical Office’s records of causes of death, and labor statistics were used to estimate the cost of epilepsy. Patients were defined as those who were hospitalize

Abstract Since 1970’s rapid urbanization and economic growth, the population was highly increasedand residential type was changed from single detached house to high density and high-riseapartment. Recently more high-rise residential building generates more traffic volumes and itmakes spatial concentration. The highly traffic volumed road and high residential building wasconstructed nearby, it occurs noise problem.The purpose of this study is comparing the performance of three type noise barrier
