The purpose of this study is to verify the impact on social responsibility activities of food service companies on trust of and the intention of paying premium prices. Social responsibility activities were eco-friendly products, volunteer activities, and donation activities, and trust and premium price payment intentions consisted of one element. In order to achieve the purpose of this study, an online survey was conducted using convenience sampling methods of non-probability sampling methods of those who are aware of the social responsibility activities of restaurant companies and have purchased products of the restaurant companies. The results of the hypothesis are as follows . (1) Eco-friendly products and volunteer activities have a positive impact on customer trust. (2) Trust has a positive effect on the intent to pay the premium price. (3) Eco-friendly products and volunteer activities affect the intention of paying the premium price through the medium of trust in customers. The results of this study present theoretical and practical implications for the social responsibility for food service companies.

Cancer developes through the interaction of genetic and environmental factors. Cancer progresses through the accumulation of multiple genetic mutation and epigenetic changes. Diet constituents, by itself or its metabolite, regulate transcription of gene and are related to signal of proliferation, apoptosis, carcinogen metabolism and repair of DNA. Recently, it is known that tumor suppressor gene is inactivated by methylation of CpG island. It is not clear that epigenetic mechanism, especially abnormal methylation of the promoter gene, is related in colorectal adenoma. We investigated the methylene tetrahydrofolate reductase (MTHFR) polymorphism (C677T and A1298C) and methylation of the promoter gene in colorectal adenomatous polyp patients in contrast to control cases with normal mucosa. Test cases (n=14) were diagnosed with colonoscopically confirmed adenomatous polyps in bundang hospital of Seoul National University control cases (n=6) were obtained from bundang jesaeng hospital and with polyp-free by colonoscopy. C667T (28.6% vs 0%) and A1298C (71.4% vs 50%) of MTHFR polymorphisms were more frequent in adenomatous polyp patients. Abnormal methylation of promoter UCHL1 (50% vs 0%), E-CAD (35.7% vs 0%), p16 (21.4% vs 0%), BRCA1 (14.3% vs 0%), MAGE-A (21.4% vs 0%), GSTP1 (14,.3% vs 0%), DAP kinase (28.57% vs 16.7%) and ppENK (50% vs 33.3%) were more frequent in colorectal polyp patients than in controls.
