Background/Aims: The prevalence of hepatitis C virus (HCV) infection in Korea exhibits significant geographic variation, with it being higher in Busan and Jeonam than in other areas. The reason for this intranational geographic difference was investigated in this study by conducting a comparative analysis of the risk factors related to HCV infection among three geographic areas: the capital (Seoul), Busan, and the province of Jeolla. Methods: In total, 990 patients with chronic HCV infection were prospectively enrolled at 5 university hospitals located in Seoul (n=374), Busan (n=264), and Jeolla (n=352). A standardized questionnaire survey on the risk factors for HCV infection was administered to these three groups of patients, and a comparative analysis of the findings was performed. Results: The analysis revealed significant regional differences in exposure to the risk factors of HCV infection. By comparison with patients in Seoul as a control group in the multivariate analysis, patients in Busan had significantly more experience of invasive medical procedures, acupuncture, cosmetic procedures, and multiple sex partners. In contrast, patients in Jeolla were significantly older, and they had a higher prevalence of hepatocellular carcinoma, a lower prevalence of multiple sex partners, and had experienced fewer invasive procedures. Conclusions: There was a significant geographic difference in the exposure to potential risk factors of HCV infection between patients from the three studied regions. This may explain the regional variation of the prevalence of HCV infection in Korea, and should be taken into account when planning strategies for the prevention and management of HCV infection.

Ku J, Lee JH, Han K, Kim SI, Kang YJ, Park ES: Validity and reliability of cognitive assessment using virtual environment technology in patients with stroke. OBJECTIVES:: We assessed the validity and reliability of a virtual environment technology (VET)-based cognitive assessment program that was developed as a measurement tool of cognitive abilities in patients after a stroke. DESIGN:: Twenty participants diagnosed with stroke caused by unilateral brain lesions were enrolled to assess the VET program’s validity and test-retest reliability. Participants underwent evaluation by paper-based neuropsychological tests including the Korean Mini-Mental Status Examination, the Korean-Wechsler Adult Intelligence Scale, the Motor Free Visual Perception Test, Rey-Kim Memory Test, and Kim’s Frontal-Executive Neuropsychologic Test as well as the VET-based cognitive assessment. Major variables and indices of the VET program were calculated. The VET program validity was evaluated using a simple correlation analysis between variables from the VET program and conventional paper-based neuropsychological measurements, and the reliability was evaluated by investigating the test-retest correlation coefficients. RESULTS:: Major variables and indices of the VET program in patients with stroke correlated significantly with the related scores of paper-based neuropsychological tests. In addition, the test-retest reliability analysis revealed that the correlation coefficients ranged from 0.528 to 0.926. CONCLUSION:: The VET-based cognitive assessment program showed adequate reliability and validity as a method of cognitive assessment in patients after stroke.

In this paper, we propose a method generating of instance ontology from web pages for the lodge. First, we analyze non-structured web documents and generate information extraction rules in order to extract specific informations from web sources. And we extract the informations from various web pages related to lodge using generated rules. And then ontology instances are automatically generated through adding OWL semantic information to the extracted informations. Our method is able to cut down on time and cost than a method which generates various ontology instances manually. Also agents can search the information corresponding to semantically what the user needs in the various web pages using numerous vocabulary having same meaning and provide good quality of informations to user.

The objective of this study is to identify perception, knowledge, test and infection about VD for prostitutes. The subject of this study consisted of 343 prostitutes who were registered in 2 community health centers in Taegu and data was collected from January 12th to 17th, 1987. The results were as follow. 1. Mean of STD test was 22.37 and VDRL test was 1.63 during 6 months. Mean number of infection of VD was 2.82 during 6 months. 2. In the perception about VD, the majority of the subjects perceived VD as some susceptibility, low potential for mortality and often thought and discussed. Regarding public concern about VD, the majority perceived VD as non-socially acceptable disease. In the knowledge about VD, all most of the subjects had relatively high level of knowledge. 3. As the level of STD test according to the general characteristics, high group received more test than lower group in age. As the number of infection, below 1 year and alien group were higher than above 1 year in prostitution period and Korean in partener of prostitution. There were no differences in other characterristics. 4. As the level of perception according to general characteristics, high group was higher level of susceptibility than low group in age. Below middle school group was higher level of potential for recovery and mortality than above high school group in education. Also above 1 year group in duration of prostitution perceived VD as dirty but acceptable disease and alien group perceived more painful disease than Korean group in partener of prostitution. As the level of knowledge, above high school group and alien group were higher level in reason of need for regular VD test than below middle school in education and Korean group in partener of prostitution. In the VD itself and test method, below 1 year group was higher level than above 1 year group in period of prostitution. 5. As the level of perception according to STD level high group perceived VD as more painful disease, and less public concern than low group in STD test. But there were no differences in general.

본 연구는 접경지역의 낙후현상에 대한 법적·제도적 차원의 정책적 해법을 취급하고 있다. 구체적으로 접경지역의 낙후현상은 단편적 규제주의, 국가안보의 특수성과 생태환경의 보존성에 대한 결과로서 검토된다. 이와 같은 점에서 본 연구의 주된 관심은 규제와 개발의 상호주의 관점에서, 접경지역의 낙후현상에 대한 원인규명과 해결책을 제시하였다. 특히 이론적 시각에서 접경지역의 낙후현상에 대한 분석모형을 설계하였으며, 이를 토대로 실증적 차원에서 접경지역의 낙후현상을 분석하였다. 연구결과는 접경지역의 사회적 가치상승에 따른 새로운 시각에서 접경지역의 낙후현상을 해결하기 위한 법적·제도적 차원의 개선방안이 필요하다는 주장이다. 특히 본 연구는 강원도 접경지역을 대상으로 수행하였고, 그 결과 접경지역에 대한 새로운 발전시각의 정립, 법·제도적 차원의 종합적인 관리대책, 지역낙후성 문제의 원인과 해결방안 등을 제안하였다.

In the super slow speed die casting process, the casting defects due to melt flow should be controlled in order to obtain sound casting products. The casting defects that are caused by molten metal were cold shut formation, entrapment of air, gas, and inclusion. But the control of casting defects has been based on the experience of the foundry engineers. The calculation of simulation can produce very useful and important results. The calculation data of die casting process condition from the computer simulation by the Z-CAST is made to insure that the liquid metal is injected at the right velocity range and that the filling time is small enough to prevent premature solidification. The parameters of runner shape that affected on the optimized conditions that was calculated with simple equation were investigated. These die casting process control techniques of automobile valve body mid-plate have achieved good agreement with the experimental data of tensile strength, hardness test, and material structure photographies satisfactory results
