Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.

In this paper, the fabrics for Korean folk clothes(KFC) undergoes repeated laundering under given condition. After this cyclic laundering was applied, the mechanical properties of the specimen were measured using KES-F system in order to evaluated the end-use performance of fabrics for KFC. And also, the crease recovery of fabrics for KFC were measured by shirley crease recovery tester. 78 different kinds of commercial silk fabrics and polyester fabrics for KFC were used for this study. The experimental results were analysed statistically to relate the mechanical properties and the crease recovery of fabrics for KFC. Furthermore, these changes in dimensional stability, mechanical properties and handle of fabrics for KFC were discussed in comparison with those values for silk fabrics and polyester fabrics. The results obtained are as follows. 1. Regardless of materials, remarkable increase are observed in shrinkage of the fabrics for KFC about repeated laundering, but dull increase are observed in shrinkage after 10 cycles of the repeated laundering. On the other hand, slack extend are observed in dimensions after 20 cycles of the repeated laundering. The shrinkage of fabrics for KFC after 10 cycles of the lundering showed that the silk fabrics are 1.74±0.33% (warp direction) and 1.35±0.23% (weft direction) and the polyester fabrics are 1.45±0.22% (warp direction) and 1.25±0.23% (weft direction). 2. Except for tensile property, these changes in mechanical properties of fabrics for KFC by laundering have ±16 range of bending, shearing, compression, surface, thickness & weight as compared with before laundering. Particularly, the LT and RT about 1∼3 cycles of the repeated laundering showed remarkable decrease. And SMD, WC, T & W of fabrics for KFC by the laundering were more increased than one for original fabrics. But B, 2HB, G, 2HG, 2HG5 were decreased more than one for original fabrics. 3. "Stiffness", "Anti-drape", "Crispness" and "Scroop" hand values decrease and"Fullness & softness", "Flexibility & softness" hand values increase with repeated laundering. 4. Remarkable decrease are observed in crease recoveries about 1∼5 cycles of the repeated lundering, but slack decrease are observed in crease recoveries after 5 cycles of repeated laundering. The crease recovery of fabrics for KFC have negative(-) correlation with LT, RT, G, RC and MMD, This fact implies that the smaller these values, the larger the crease recovery. The crease recovery of fabrics for KFC has a high degree of correlation with the mechanical properties such as shearing, compression, surface property. And also, the crease recovery are expected by measuring the mechanical properties such as G, 2HG, 2HG5, RC, WC, LC, MIU, MMD and SMD, according to the obtained regression equation.

Three kinds of knitted fabric such as core, polyester/cotton(P/C), and cotton were repeatedly washed, and then used as specimen. Thermo Labo Ⅱ type was employed to measure the thermal properties of warmth retaining and contact warm/cool feeling. And also, the experimental results were analysed statistically to related the thermal properties and structural properties such as thickness, weight, bulk density, porosity, cover factor, and air permeability. The results are as follows. 1. The warmth retaining and the contact warm/cool feeling were remarkably changed at early washing, and after further washing no changes occured. The change rate of the materials to repeated washing was in the order of cotton>P/C>core knitted fabrics. 2. In case the knitted fabric of the same thickness and of the same weight have been considered, the warmth retaining was in the order of P/C>core cotton knitted fabrics. And also, the contact warm/cool feeling was in reverse order of the warmth retaining. 3. The warmth retaining showed positive correlation with thickness, weight, porosity, and cover factor and negative correlation with bulk density, and air permeability. And also, the contact warm/cool feeling showed an opposite trend to the warmth retaining 4. The warmth retaining and the contact warm/cool feeling were expected by measuring the structural properties such as thickness, weight, bulk density, porosity, cover factor, and air permeability according to the obtained regression equation.

This study is to examine the thermal properties such as the heat keeping property and the warm/cool feeling of quilting underwear, using Thermo Labo Ⅱtype. The specimens used for this study are five kinds of quilting underwear and each one of cotton and wool underwear. The correlativity is investigated by measuring the structural properties under the standard condition(20℃, 65% RH) and the thermal properties in changing the relative humidity of 55, 65, 75, 85, 95% at 20℃. The summarized results of this studies are as follows. 1. The heat keeping rate and the qmax value of quilting underwear have a high degree of correlation with structural properties such as thickness, bulk density and porosity. As above results, the regression equation is as follows. Y_HK=1.2950X_p-85.6586X_D-3.7254X_T-37.7610(r^2=0.9566) Y_qmax=154.7298×10^-3X_D-14.3396×10^-3X_T+0.2703×10^-3X_P+0.0557(r^2=0.9707) 2. The heat keeping rate of specimens is in the order of quilting underwear > wool underwear > cotton underwear. And also, the qmax value of specimens is in the order of cotton underwear > quilting underwear > wool underwear. 3. In according to increase of the relative humidity, the heat keeping rate tends to be lower but the qmax value is to be larger. Therefore, the degree of decrease of the heat keeping rate is in the order of cotton underwear > wool underwear > quilting underwear and the degree of increase of the qmax value is in the order of cotton underwear > quilting underwear > wool underwear. And also, in the fiber content per areal weight composing quilting underwears, the degree of change of the thermal properties by changing relative humidity is remarkable when hydrophilic fiber content comes to be greater.
