Objectives: Chemicals derived from various environment media contaminates food across the food supply chain. In Korea, levels of contaminants in food have been sporadically measured by monitoring programs of different government agencies. There is difficulty with data compilation and integrated analysis across media. Therefore, the aim of this study was to propose an overall integrated database and analytical platform design for the 'ECO-FOOD NET (Environmental COntaminant reduction platform for FOOD through an interagency collaboration NETwork)', a tool to support the reduction of environmental contaminants in food. Methods: We developed a new data structure and standardized protocols for the compilation of integrated data. In addition, we conducted subject-oriented logical and physical relational database modeling and created the architecture design of the platform. Results: We established a standardized code system related to exposure media and route, analysis method and food matrix. In addition, we designed the seven software modules of 'About the System', 'Introduction to Interagency Work', 'Media-Chemicals Profiles', 'Method Bank', 'Monitoring Data Base', 'Integrated Media Analysis', and 'Risk-Benefit Analysis'. Conclusions: This study will contribute to decision-making as a tool for executing risk management, such as sustainable reduction policies of contaminants in food.

This paper reviewed the relationship between perceived justice and service quality, and the moderating effect of gender in the franchise system of food service business. Based on the responses from 135 franchisees, the results of multiple regression analysis showed that distributive and procedural justice have positive relationships with almost service quality factors. The results of moderating analysis showed that male franchisees have more positive relationships with almost service quality factors than female franchisee while in distributive justice, and that female franchisees have more positive relationships with almost service quality factors than male franchisee while in procedural justice.

In order to create a worker-friendly environment for institutional foodservice, facilities operating with a dry kitchen system have been recommended. This study was designed to compare the work safety and work environment of foodservice between wet and dry kitchen systems. Data were obtained using questionnaires with a target group of 303 staff at 57 foodservice operations. Dry kitchen facilities were constructed after 2006, which had a higher construction cost and more finishing floors with anti-slip tiles, and in which employees more wore non-slip footwear than wet kitchen (76.7%). The kitchen temperature and muscular pain were the most frequently reported employees' discomfort factors in the two systems, and, in the wet kitchen, "noise of kitchen" was also frequently reported as a discomfort. Dietitian and employees rated the less slippery and slip related incidents in dry kitchens than those of wet kitchen. Fryer area, ware-washing area, and plate waste table were the slippery areas and the causes were different between the functional areas. The risk for current leakage was rated significantly higher in wet kitchens by dietitians. In addition, the ware-washing area was found to be where employees felt the highest risk of electrical shock. Muscular pain (72.2%), arthritis (39.1%), hard-of-hearing (46.6%) and psychological stress (47.0%) were experienced by employees more than once a month, particularly in the wet kitchen. In conclusion, the dry kitchen system was found to be more efficient for food and work safety because of its superior design and well managed practices.

미국선녀벌레 생물적 방제를 위한 기생성 천적인 선녀벌레집게벌 대량사육 체계를 구축하였다. 선녀벌레집게벌 고치 생산은 기주인 미국선녀벌레 약충밀도와 기주식물의 재식밀도에 따른 차이를 보였지만, 뽕나무 기주식물 잎당 평균 5~8개, 주당 평균 70~150개가 생산되었다. 선녀벌레집게벌 암컷 평균 고치 길이는 6.01~6.46 mm, 수컷은 4.20~4.62 mm로 암수 간 통계적으로 유의미한 차이를 보였으며, 우화 전 고치상태에서의 암수 구분으로 선녀벌레집게벌을 효과적으로 방사할 수 있을 것으로 보인다. 반야외조건에서 선녀벌레집게벌 기생률은 평균 13~17%로, 방사 마리수에 따른 기생률 차이는 확인되지 않았으나 방사 마리수가 많을수록 미국선녀벌레 개체군밀도증가율이 낮아지는 경향을 보였다. 선녀벌레집게벌의 성비나 이화성은 기주의 영기에 따라 달라졌다. 기주의 영기가 낮을수록 이화성 비율이 증가했고, 4~5령 약충에 기생시 암컷의 비율이 높게 나타나 대량사육 시 개체조절이 가능할 것으로 판단된다.

In terms of food safety,mixture of contaminants in food is a serious problem for not only consumers but also manufacturers. In general, the target size of the metallic contaminant to be removed is 0.5 mm. However, it is a difficult task for manufacturers to achieve this target, because of lower system sensitivity. Therefore, we developed a food contaminant detection system based on high-Tc RF superconducting quantum interference devices (SQUIDs), which are highly sensitive magnetic sensors. This study aims to improve the signal to noise ratio (SNR) of the system and detect a 0.5 mm diameter steel ball. Using a real time digital signal processing technique along with analog band-pass filters, we improved the SNR of the system. Owing to the improved SNR, a steel ball with a diameter as small as 0.3 mm, with stand-off distance of 117 mm was successfully detected. These results suggest that the proposed system is a promising candidate for the detection of metallic contaminants in food products.

본 연구에서는 식중독을 일으키는 병원균인 Escherichia coli O157:H7이 주요 소비 엽채류인 상추에서의 생장 가능성과 온도대별 생장변화를 구명하기 위하여 상추잎 즙액 에서 E. coli O157:H7의 생장, 상추잎 표면에서의 생장, 여러 가지 온도조건하의 상추잎 즙액 및 표면에서 E. coli O157:H7의 생장, 초기 접종 농도별 생장패턴을 조사하였다. E. coli O157:H7은 상추잎 즙액에서 20시간 이내에 밀도가 증가하였고 상추잎 즙액의 농도에 따라 병원균의 생장률은 다르게 나타났다. 조사기간 동안 $4^{\circ}C$ 조건에서는 E. coli Ol57:H7 밀도가 크게 변하지 않았고 $15^{\circ}C$ 이상의 조건에서는 10시간 이내에 밀도가 증가승하는 것을 확인할 수 있었다. 상추잎 표면에서도 E. coli Ol57:H7의 밀도는 초기 접종 밀도에 비해 증가하였고, 증가되는 정도는 온도가 높아질수록 증가율이 높은 것으로 나타났다. 상추의 E coli O157:H7 초기 오염 농도가 병원균의 최대 생장 밀도 에 큰 영향을 미치는 것으로 확인되었다. 따라서 본 연구 결과로부터 상추잎에서 식중독세균인 E. coli O157:H7의 생장이 일어나는 것을 확인하였고, 이는 온도의 영향을 많이 받는 것으로 나타났다. 위의 결과에 따라 농식품 안전성 확보를 위해서는 신선 엽채류는 생산 유통 소비 단계 에서 유해미생물의 오염을 예방하는 것이 중요하고 특히 유통과 소비단계에서 저온도 유지가 철저히 이루어져야 할 것으로 사료된다.

Since 1986, domestic sewage treatment plants have installed and operated biogas plants that produce biogas (digested gas) using food, livestock manure and sewage sludge as part of the use of alternative energy for energy independence. Despite concerns about safety accidents and risks of large-scale accidents due to the continuous expansion of biogas plants, the Ministry of Environment has managed and supervised biogas plants to be environmental plants, focusing on environmental management. There is a lack of safety awareness of workers' processes. Only recently has the process safety management (PSM) system been implemented in biogas plants, but workers' perceptions of process safety have changed. As there is a difference in the degree of safety process management and safety awareness among workers, it is necessary to establish clear and systematic safety management standards. Therefore, The purpose of this study is to examine whether the application of the plant safety management (PSM) system to biogas plants is effective for workers' safety awareness in order to ensure safe operation of biogas plants and prevent workers' safety accidents in advance.
