Global warming caused by greenhouse gases is threatening our ecosystem. Moreover, our food system is in severe danger. Recently the local food system is emerging as an alternative food network, decreasing food miles and carbon dioxide emissions, protecting the safety of our foods, and helping local economy. However, carbon labelling for agricultural products has not been introduced yet in Korea. Accordingly, research on food miles and carbon labelling for agricultural products should be urgently conducted. The study compared the food miles and the carbon dioxide emission of major agricultural products. In addition, the food mileages of garlic and carrot are compared between Korea and China. The results show that radish has the highest carbon dioxide emission, and followed by onion and cabbage. These products are produced from Jeju island and have a high Shipment volume. Although Chinese Garlic and radish have lower shipping volume and food miles than Koreans, they have higher carbon dioxide emissions due to ship transportation. Based on these results some valuable implications can be identified. Current food distribution system, which heavily focuses on the Metropolitan area, should be changed into a local system, in which foods are consumed in the local area first then transported to other area.

The objective of this study was to investigate the effect of dietary education on undergraduate student's health, environment, and consideration. A total of 54 participants were recruited from an undergraduate student in Seoul. We conductive quantitative analysis of a structured questionnaire and qualitative analysis of interviews recorded by photovoice. There are significant differences among knowledge, dietary attitude, and food behavior in the field of health (p<0.001). In the field of health, photovoice data were categorized as 'health care practice', 'Korean dietary lifestyles', or 'awareness of importance of health' (p<0.001). In the field of environment, photovoice data were categorized as 'environment-friendly dietary lifestyle' and 'environmental contamination minimization'(p<0.001). In the field of consideration, photovoice data were categorized as 'gratitude for others', 'joy of cooking'or 'eating meals together'(p<0.01). In conclusion, we found that dietary education about health, environment, and consideration may affect healthy dietary lifestyle among undergraduate students. Our findings may warrant further studies to develop significantly effective dietary education for undergraduate students.

Kudoa septempunctata has been reported as a new parasite in aquacultured olive flounder Paralichthys olivaceus, and also as a causative agent of food poisoning in humans. This paper investigated the infection of K. septempunctata in 216 sashimi and 20 sushi made of olive flounders in Busan, Korea. Among 236 samples, K. septempunctata was detected in eleven sashimi with 6-7 polar capsules by the microscopy. Among eleven sashimi, five sashimi were positive in Polymerase Chain Reaction (PCR) assay with the targets of 18S rDNA and 28S rDNA. The genotype of all the five PCR results is identified as the genotype ST3 which is common in Korea. K. septempunctata was found in olive flounders sashimi from Samcheonpo and Wando outside of Jeju Island. These findings would contribute to establish the standard of K. septempunctata for preventing food-borne outbreaks in advance and providing further preventive management for the seafood safety.

Objectives: This study was performed to provide basic data for the re-establishment of standards (criteria) and analytical methods for hazardous metals in nail enamel. Methods: Ten metals (lead; Pb, arsenic; As, cadminum; Cd, antimony: Sb, cobalt; Co, nikel; Ni, copper; Cu, chromium; Cr, aluminum; Al, and mercury; Hg) were measured in 67 commercial nail enamels containing glitter and/or pearls. The content of hazardous metals (excepting Hg) was determined by using an inductively coupled plasma-optical emission spectrophotometer (ICP-OES) after microwave digestion. Mercury content was measured by a mercury analyzer without any preparation. Results: The detected ranges of the intact samples were as follows: $ND-1.756{\mu}g/g$ for Pb, $ND-1.24{\mu}g/g$ for As, ND for Cd, $ND-20.41{\mu}g/g$ for Sb, $ND-12.36{\mu}g/g$ for Co, $ND-7.908{\mu}g/g$ for Ni, $0.088-79.27{\mu}g/g$ for Cu, $0.281-18.54{\mu}g/g$ for Cr, $13.78-3563{\mu}g/g$ for Al, and $ND-0.044{\mu}g/g$ for Hg. After centrifugation, the detected ranges of supernatant were as follows: $ND-0.435{\mu}g/g$ for Pb, $ND-0.504{\mu}g/g$ for As, ND for Cd, $ND-0.035{\mu}g/g$ for Sb, $ND-13.17{\mu}g/g$ for Co, $ND-0.232{\mu}g/g$ for Ni, $0.117-90.07{\mu}g/g$ for Cu, $0.174-2.787{\mu}g/g$ for Cr, and $9.459-1565{\mu}g/g$ for Al. The results of this analysis showed that the levels of heavy metals such as Pb, As, and Sb were much higher in the intact samples than those of supernatant. Conclusion: In the present study, we found that the levels of hazardous metals were significantly different depending on the status of the presence of glitter. Based on the results, we recommend that the product consumer refrain from prolonged application of nail enamel, avoid biting or chewing the nails, and wear gloves during cooking and washing dishes.

Treatment of food waste is becoming a big issue due to their significant quantities. Composting could be an effective alternative for food waste management which could be used as soil conditioner or fertilizer with little concerns about heavy metals and pathogens. The purpose of this research was to evaluate the effect of food waste on Chinese cabbage growth and soil properties. 9 different treatments (two livestock manures, two food wastes, two livestock manures + chemical fertilizer, two food wastes + chemical fertilizer, and control) were applied to Chinese cabbage. All treatments were carried out in 3 replicates. We measured leaf length, leaf width, fresh weight, dry weight, and leaf greenness of Chinese cabbage. Treatment of one of food waste composts significantly increased leaf length and leaf width of Chinese cabbage by 28.6, 26.6, 67.7, and 59.9%, respectively, in comparison to those of control, while no significant differences for leaf greenness were shown. Application of food waste compost resulted in significant increase of EC, available $P_2O_5$, CEC, organic matter, and exchangeable cations. However, further researches are needed to reduce NaCl content of food waste.

As a result of analysis on situations of environment-friendly school meals, it was obtained that student's parents were interested in food safety and the importance of sanitary supervision. Many parents responded that environment-friendly school meals increased the health and eating habits of their children. The higher and higher educated parents responded that environment-friendly school meals effected on the children's health positively. Also, the higher educated parents responded that environment-friendly school meals effected on the children's eating habits positively. After the environment-friendly school meals, the item increase to purchase was vegetables by 25% of the consumers who purchase environment-friendly agri-products. The second and third increasing items were respectively fruits and rice. When environment-friendly agri-products were consumpted and influenced positively through school meals, the consumption of environment-friendly agricultural products will be increased. The expansion of environment-friendly school lunch program cannot bring the consumption expansion of environment-friendly agri-products immediately. However, when the persistent promotion and student's parents confidence on environment-friendly agri-products were accumulated and experienced positive effects through school meals, it will give a positive effect on the consumption of environment-friendly agr-products.
