This study investigated the hazard factors based on imported food non-compliance and global food hazard information for the last 4 years to suggest imported food safety management. Food safety management on utensils or packaging containers is appropriately managed for the compounds derived from them. Food safety management on health-functional foods, processed foods, and agricultural products is concentrated on ingredient contents, food additives, and pesticide residuals. Additional hazards are illegal compounds, mycotoxins & pesticide residuals, hygieneindicator microorganisms and food-borne pathogens in health-functional foods, processed foods, and agricultural products, respectively. The continuous increase in hazards related to safety and hygiene in global food hazard information needs additional attention. To reduce the hazard factors, this study proposes that imported food be limited to products certified by HACCP or an equivalent food safety management system because registering foreign food facilities for processed and health-functional foods is mandatory. Additionally, the customs clearance inspections should focus on the hazard factors derived from the global food hazard information system. This study suggests a global food hazard information system that could derive frequently issued hazard factors at a given period and newly issued hazard factors in aspects, such as food items, subcategories, and exporting countries.

Most of methane gas result from waste matter in landfill, therefore the persons concerned take an increasing interest in management of gases in landfill. Infrared Gas Analyzer was used to measure components of gases, CH4, CO2, O2, through gas exhausted pipe. To measure amount of the gas flow meter(Portable Hot-Line Current Meter) was used and it was set at right angles with direction of the flow. In this research the total amount of methane gas produced in Beck-Suk Landfill was calculated through FOD method suggested by IPCC. This research found that in Chon-An Beck-Suk Landfill anaerobic resolution was made actively and the amount of methane gas produced there was 54.14%, which is higher than common figure, 50%, in other researches. The components of reclaimed waste matter, especially, organic waste matter can have a great effect of the amount of the greenhouse gases produced in landfill. We can expect that the amount of greenhouse gas will decrease from 2005, when it will be prohibited from carrying kitchen refuse and sludge into landfill.
