Background/Aims: Benign gastric tumors are rare. Since the advent of gastrofiberscopy, the diagnosis of benign gastric tumors has increased so, their management has become important. The aim of this study was to determine its treatment method through exact diagnosis. Methods: Eighty-two cases of benign gastric tumors which had been treated at the Soonchunhyang University Hospital from January 1992 through December 1998 were analysed. Results: The incidence of benign gastric tumors were 11.7% of all gastric tumors in this period. Of the all benign gastric tumors, 52.4% were epithelial polyps and 68.5% (50 cases) occurred in females. The age of patients ranged from 21 to 78 years and the incidence peaked in 6th decade (32.9%). The most common lesion of tumor was antrum of the stomach in 35 cases. The size of the tumor was less than 10 mm in diameter in 42 cases. Endoscopic polypectomy were performed in 40 cases (48.8%) and open laparotomy were performed in 42 cases (51.2%). Conclusions: These results suggest that when surgical treatment was needed for gastric tumor, the pathological test of frozen section at the time of operation is essential and the treatment method should be dictated by its results.

The purpose of this study is to investigate the relationship between the subjective well-being and the continuance intention by the heuristic decision-making of consumers who purchase maturity high-tech products (smart-phones and tablet PCs). The use of heuristics and selection factors consisted of personal factors (shopping tendency, knowledge, experience), product factors (brands, attributes, symbolism), environmental factors (overload of alternative choices, time constraints), and subjective well-being was divided into two dimension such as life satisfaction and emotional well-being. A total of 245 questionnaires were collected from JeJu consumers who has experience using smart-phones and tablet pc. As a structural equation model result, Other factors except environmental factors showed a significant effect on subjective well-being, and subjective well-being had a significant effect on continuance intention. These results suggest that the companies is to create a platform that can provide detailed information about the product and a positive experience so that heuristic decision-making can increase satisfaction.

Villous adenomas of the ampulla of Vater are uncommon lesions. They are often overlooked as a cause of extrahepatic cholestasis, and in the past the diagnosis of ampullary tumors has been most often made during surgery and on autopsy. Recently, the early diagnosis of ampullary tumor has become possible due to the wide application of fiberoptic endoscopy and increasing knowledge about ampullary tumors. We experienced three cases of the tubulovillous adenoma developed in the ampulla of Vater. The diagnosis of these tumors was all made by intraampullary biopsy after an abnormality was discovered via the fluoroscope during endoscopic retrograde cholangio- pancreatography (ERCP). We recommend an aggressive endoscopic study with ERCP in the diagnosis of obstructive jaundice, as early diagnosis is the key to adequate treatment and satisfactory results. Upon diagnosis of ampullary villous adenoma, the complete resection of the tumor is recommended due to the high risk of recurrence and malignant transformation.
