Objectives : Gastric cancer is the most common incident cancer in Korea. Although Helicobacter pylori infection is the most important risk factor for the development of gastric cancer, cigarette smoking has also been suggested to play an important role in the development of gastric cancer. The objective of this study is to evaluate the relationship between cigarette smoking and gastric cancer risk in a Korean population. Methods : The study population consisted of 13,785 subjects who had been enrolled in the Korean Multi-Center Career Cohort between 1993 and 2002. As of December 2002, 139 incident gastric cancer cases were ascertained through the Korea Central Cancer Registry and the National Death Certificate Database. Relative risks (RR) and 95% confidence intervals (CI) for gastric cancer were estimated using Cox#s proportional hazard model adjusted for age, education, alcohol drinking status and history of gastritis or ulcer. Results : Significant dose-response relationships were observed between the duration of smoking and the risk of gastric cancer among the male subjects in comparison to non-smokers: men who smoked for 20-39 years had a 2.09-fold (95% CI 1.00-4.38) increase, and those who smoked for more than 40 years had a 3.13-fold (95% CI 1.59-6.17) increase in the risk of gastric cancer ($P_{trend}<0.01$). Conclusions : This study suggests that a longer duration of cigarette smoking may increase the risk of gastric cancer development in a dose-response manner in Korean men. The association between smoking and gastric cancer risk in women should be verified in future studies with a larger number of cases.

Effects of pH and temperature on shrinkage of grey knits (slip) and effects of scouring renditions on shrinkage, reflectance, handle and reactive dyeing Properties of loon cotton warp knits were studied. The results are as follows. In solution of room temperature and pH 71-13 the maximum area shrinkage was about 20%, pH has no effect on area shrinkage but on linear shrinkage. Three dimensional the loop which caused a knit to shrink was caused by the twist of yarn. Temperature has no effect on area shrinkage of grey knits. In mixed solution of sodium hydroxide and soda ash, the decrease of concentration ratio of soda ash made the reflectance decrease and the softness increase. Equilibrium adsorption was decreased as the pH of dye bath increased but the maximum fixation was obtained at pH 10. Scouring conditions have some effect on the rate of adsorption but a few effect on the rate of fixation.

Purpose: This study compared the thigh circumference and Lysholm scale of a stable and unstable exercise group of patients who had undergone an anterior cruciate ligament reconstruction (ACL reconstruction). Methods: The subjects were patients more than 4 weeks after their ACL reconstruction and could stand on one leg. The patients were divided into a control group with 9 patients performing closed kinetic chain exercises on a stable floor and an experimental group with 10 patients performing closed kinetic chain exercises en an unstable floor. The degree of muscle atrophy was compared by measuring the circumference of the injured thigh before the exercise program, and 3 weeks and 6 weeks after the exercise program. The Lysholm scale was used to assess the function of the knee joint. Results: There was no significant increase in thigh circumference according to the exercise periods in the two groups. However, there was a statistically significant increase before exercises and 6 weeks after the exercises (p<0.05). There were statistically significant differences in the Lysholm scores between the two groups (p<0.05). Conclusion: There were no statistically significant increase in the two groups, but there was a significant difference between before the exercise program and 6 weeks after the exercise program (p<0.05).
