This study was designed to compare the effect of polishing on surface roughness of composite resin. We used Z100(3M) composite resin and placed the composite resin in the hole (4mm thick and 4mm in diameter) of vinyl plate and polymerized it under manufacturer's instructions. Samples were divided into 5 groups by polishing methods. Group 1 was control: resin was polymerized under glass plate, Group 2: resin was polymerized without any polishing procedure, Group 3: resin was polymerized with a polishing procedure of abrasive disc, Group 4: bonding agent was applyed in thin layer an polymerized on the polished polymerized resin surface, Group 5: resin was polymerized under transparent celluloid strip. The surface roughness of each specimen was measured with Sufacoder SEF-30D (Kosaka lab. Ltd) under 0.08mm cut off, 0.05mm/s stylus speed, x40 horizontal magnification, x5000 vertical magnification. The results were as follows : 1. Group 1 showed the most smooth surface in this study. 2. Group 3 showed more rough surface than Group 2. Considering the surface roughness, it would be better to make the shape completely before polymerize the resin. To finish and polish after the polymerization of resin makes less smooth surface. 3. When we use the transparent celluloid strip, minimum finishing procedures are recommended. Any polishing procedure could not recover the smooth resin surface of celluloid strip. 4. Application and polymerization of the thin layer of bonding agent on the polished surface showed the minimum surface smoothing effect.

Stomach cancer is one of the major causes of cancer deaths in Korea. It has been well known, like other solid tumors, that cancer stage at diagnosis is the most important prognostic factor in gastric cancer. Previous studies from Japan have revealed that screen-detected gastric cancers showed an earlier stage distribution and had a lower mortality rate than symptom-diagnosed cases. Considering the high provalence and substantial mortality from gastric cancer in Korea, it seems necessary to establish a well organized nationwide screening program. In this regard, consensus meeting was held in January, 2002 in conjunction with The Koean Gastric Cancer Association and National Cancer Center in Korea. In this meeting, specialists from gastroenterology, surgery and radiology drew a conclusion as follows : biannual screening for people aged 40 years and over either by endoscopy or upper gastrointestinal series. During the screening endoscopy, biopsy can be performed if necessary, and specimens should be examined by pathologist. Screening test should be performed in authorized hospital or mobile unit by qualified doctors.
