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.

This study was conducted on a population of 92 male adults residing in Seoul and took as its related variables age groups (30th, 40th, and 50th), sports participation degrees (active, average, and negative), participation frequencies (less than 1 time a week, 2 or 3 times a week, and more than 4 times a week) and participation terms (less than 3 months, 3 to 6 months, 7 months to one year, more than 1 year). And then taken as its subvariables were factors related to male adults' physical fitness (abdominal muscular strength, muscular sustaining power, flexibility, cardiopulmonary sustaining power). A 2way ANOVA was carried out to analyse differences among variables related to male adult's physical fitness. Resultant findings were revealed, as follows: 1. An analysis of muscular strengths among variables such as age groups (thirties, forties, and fifties), participation degrees (active, average, and negative), participation frequencies (less than 1 time a week, 2 or 3 times a week, and more than 4 times a week) and participation terms (less than 3 months, 3 to 6 months, 7 months to one year, more than 1 year), revealed statistically significant differences by age groups, while no significant differences were revealed by participation degrees and participation terms. 2. An analysis of muscular sustaining powers among variables such as age groups (thirties, forties, and fifties), sports participation degrees (active, average, negative), participation frequencies (less than 1 time a week, 2 to 3times a week, more than 4 times a week), and participation terms (less than 3moths, 3 to 6 months, 7 months to 1 year, and more than 1 year) showed statistically significant differences y age groups, while no statistically significant differences were found by sports participation levels, participation frequencies, and participation terms. 3. An analysis of flexibilities among variables such as age groups (thirties, forties, and fifties), sports participation degrees(active, average, and negative), participation frequencies (less than 1 time a week, 2 to 3 times a week, and more than 4 times a week), and participation terms (less than 3 months, 3 to 6 months, 7 months to 1 year, more than 1 year) showed statistically significant differences by age groups, while no statistically significant differences were represented by particpation degrees, participation frequencies, and participation terms. 4. An analysis of systemic sustaining powers among variables such as age groups (thirties, forties, and fifties), sports participation degrees(active, average, and negative), participation frequencies (less than 1 time a week, 2 to 3 times a week, and more than 4 times a week), and participation terms (less than 3 months, 3 to 6 months, 7 months to 1 year, and more than 1 year) reflected statistically significant differences by age groups, while no statistically significant differences were found by sports participation degrees, participation frequencies, and participation terms.

The objective of this study was to examine the validation of structure of physical self description questionnaire(PSDQ) based on the covariance structure analysis, conducting a wide survey on students involving physical activities as the subject of this study. The students were comprised of ordinary students and athletes of male and female in high schools and universities as well. To put it more specifically, this study was designed to find how the subject of the study react to the 11 multi-level structure of physical self description questionnaire created by Marsh and Redmayne. The result of this study was applied to verify the factor structure, utilizing a explomatory factor analysis program based on maximum likelihood estimation. The result of the study is shown as below. First, when the study was made to ordinary students and athletes of male and female in high schools and universities in Korea, the construct factor of physical self description questionnaire was proved to be composed of nine(9) factors which are confidence in sports, global physical, physical activity, body fat, flexibility, healthy, self-esteem, appearance, and endurance. Accordingly, the result of this study was proved to be different from eleven(11) multi-level of structure for physical self description questionnaire by Marsh and Redmayne. Second, while the validity of factor structure was verified in both eleven(11) construct factor model and nine(9) construct factor model when the study was made to all the students(in high schools and universities, male and female, and ordinary students and athletes), the nine(9) construct factor model was proved to be more adequate one than eleven(11) construct factor model.

Purpose : To evaluate accuracy and reliability of program to measure facial soft tissue thickness using 3D computed tomographic images by comparing with direct measurement. Materials and Methods : One cadaver was scanned with a Helical CT with 3 mm slice thickness and 3 mm/sec table speed. The acquired data was reconstructed with 1.5 mm reconstruction interval and the images were transferred to a personal computer. The facial soft tissue thickness were measured using a program developed newly in 3D image. For direct measurement, the cadaver was cut with a bone cutter and then a ruler was placed above the cut side, The procedure was followed by taking pictures of the facial soft tissues with a high-resolution digital camera. Then the measurements were done in the photographic images and repeated for ten times. A repeated measure analysis of variance was adopted to compare and analyze the measurements resulting from the two different methods. Comparison according to the areas was analyzed by Mann-Whitney test. Results : There were no statistically significant differences between the direct measurements and those using the 3D images (p>0.05). There were statistical differences in the measurements on 17 points but all the points except 2 points showed a mean difference of 0.5 mm or less. Conclusion : The developed software program to measure the facial soft tissue thickness using 3D images was so accurate that it allows to measure facial soft tissues thickness more easily in forensic science and anthropology.
