In 1995, the WTO started to ease the trade barriers. Globalization has accelerated. The opening of the agricultural products market is rapidly gaining momentum with the conclusion of an FTA. The acceleration of this FTA is expected to be a threat to Korea's agriculture, and a new strategy is needed. At the beginning of the nuclear accident, mainly radioactive materials are found in the surface layer of the soil. Over time, the concentration of the plant gradually increases. After 5 years, it becomes noticeable. In March 2016, it will be five years after the nuclear accident. Radioactive contamination is very likely to occur in agricultural products produced in the Fukushima area at this time. In this period, agricultural products produced in the Fukushima region are expected to generate supply disruptions in Japan, and imports to replace them will increase. Therefore, it is necessary to establish a mid- and long-term strategy for exporting to Japan by analyzing the competitiveness of Korean agricultural products. In this study, standardization index was derived by using agricultural price ratio, TSI, export CAC. Based on this, we analyzed the competitiveness of each item in the Japanese market. The analysis shows that garlic is the most competitive product in the Japanese market. Also, strawberry, tomato, and cucumber were found to be competitive. On the other hand, Kiwi, pineapple, soybean, onion, potato, etc. As a result of the analysis, the following strategies were proposed for the export of agricultural products with high competitiveness. First, it is necessary to develop technology to suppress deterioration of export transportation quality. Second, continuous supply of local consumption pattern information is required. Third, it is necessary to expand exports by processing fresh food. Fourth, it suggested the establishment of export base and strengthening of support system.

To identify correlation between fresh meat and processed meat products, we performed canonical correlation analysis (CCA) to predict the relationship between pork supply and meat product production in Korea. Results of CCA showed a canonical correlation of 0.8576 in the first canonical pair (p<0.01). The production of meat products showed the highest correlation with pork import but the lowest correlation with the production of domestic pork. Although Korean consumer preferred meat products produced by fresh domestic pork, inexpensively imported pork with high share in meat products was supplied in the market. Therefore, securing domestically produced raw meat is important for expanding consumption of domestic meat products. Results of this study suggest that meat processor and pig producer can achieve the $6^{th}$ industrialization by combining the production of raw pork materials, meat processing, and sales service.

깻잎을 생산하는 APC 시설을 대상으로 GAP system을 도입하기 위해서 각 공정별 용수 및 세척수, 작업자 및 작업장 환경, 각 공정별 깻잎 그리고 공중낙하균을 대상으로 미생물학적 위해 분석을 실시하였다. E. coli, E. coli O157 그리고 L. monocytogenes를 제외한 위생지표세균(일반세균과 대장균군)과 병원성 미생물(B. cereus와 S. aureus)이 세척수, 작업자 장갑 및 작업복 그리고 포장대 등 대부분의 항목에서 비교적 높은 수준으로 검출되었다. 특히 직접적인 교차오염의 위험이 있는 세척수와 작업자 장갑의 경우, 일반세균수는 각각 0.91-3.36과 3.31-4.29 log CFU/ (mL, 100 $cm^2$), 대장균군은 0.00-1.86과 1.16-2.06 log CFU/(mL, 100 $cm^2$)의 비교적 높은 수준으로 검출되었다. 또한 입고된 원재료에서 포장공정에 이르기까지 깻잎에서 일반세균과 대장균군이 각각 4.82-5.93과 2.82-3.49 log CFU/leaf 수준으로 분리되어 유의적인 세척효과는 없는 것으로 나타나(p${\geq}$0.05) 식중독 사고를 방지하기 위해 더욱 향상된 세척공정이 절실히 요구된다. 이와 같이 현재 APC 시설은 미생물학적 안전성을 확보하기보다는 선별 및 저장의 기능에만 초점을 맞춰 운영되기 때문에 위생적인 개념이 포함된 새로운 개념의 관리체계가 필요한 실정이다. 따라서 신선하고 안전성이 확보된 깻잎을 생산 공급하기 위해 사전예방적 안전체제인 HACCP system을 기초로 한 GAP system을 제 시함으로써 미생물학적 위해요소 관리가 도입된 새로운 개념의 농식품의 안전관리제도를 제시하였다.

Rice production in Korea began to rise significantly after 1970. Rice is the dominant food in Korea and most of the rice production (about 95%) is consumed as cooked rice. it provides over 4,000Kj of energy per capita per day. Apparent rice availability in 2000, 93.6Kg of milled rice per person annually. The non-allergenic character of rice offers a sound basis for development of products for markets for all age groups. Whole grains are washed rice, coated rice, enriched rice in Korea. Utilization of rice as food can be categorized three categories in Korea; direct food use, processed foods, and brewing. Rice for direct consumption include regular whole grain, precooked rice, brown rice and specialty products such as aseptic cooked rice, retort cooked rice and rice burger. Rice used for processed foods includes that for cereal, soup, baby food, snack, cake, noodle, brown rice tea, and minor unclassified uses. Rice use for brewing is for the production of fermented rice wine. The use of rice for direct food is by for the greatest of the three uses. Although direct food accounts for the largest domestic consumption, a significant quantity of rice is used in processed products. The use of rice by-products as human food should not be over looked. Utilization of by products(rice germ, rice bran) requires a specialized technology. Typical type of rice is black rice. When cooked, black rice gives a black color to cooked rice. Glutinous rice performs specific functions in several commercial products such as dessert, gravis, cake and snack. Rice starch production is quite limited because of the high cost of making of starch. Rice processed products in Korea are occupied small parts of total rice production compared to Japan. Rice cake (Garadog) is the principal from of rice product consumed in Korea. Rice cake and snack is usually prepared from non-glutinous milled by washing, grinding, steaming, cooling and packaging. Rice cake will be continued to be a major rice product in Korea. Rice products represent a means to study variety differences in rice grain quality, since the processing magnifies differences not normally detected from more boiling. Recently, rice processing companies in Korea are about 400 ones which uses rice about 160,000tons. New rice processed products and modified traditional products must be developed and diversified with high quality and processing properties of rice processed products are improved.

BACKGROUND: This study was carried out to determine characteristics of residual pesticides in time-dependent manner and calculate half-lives of the residual pesticides in fresh and dried Chinese matrimony vine. In addition, processing factors were calculated based on the residual concentrations in them. METHODS AND RESULTS: The test pesticides, etofenprox and fenitrothion, were sprayed onto the Chinese matrimony vine plants at once or twice (at seven-day interval) and then samples were collected at 0 (after 3 hours), 1, 3, 5 and 7 days after the last spraying. Dried samples were prepared in hot-air drying oven at $60^{\circ}C$ for 48 hours until water content of less than 20%. Residual concentrations of etofenprox in fresh and dried samples decreased by 54.0-60.9% after 7 days of the last pesticide-application. In case of fenitrothion, the concentrations were found to have decreased by 69.2-76.5%. Processing factors of etofenprox were 2.6-3.0 for the one-time spraying and 2.5-3.0 for the two-time spraying and those of fenitrothion were found to be 1.5-22 for the one-time spraying and 1.6-2.0 for the two-time spraying. First half-lives of etofenprox and fenitrothion in fresh and dried samples ranged from 5.0 to 6.3 and from 3.4 to 4.0 days, respectively. The third half-lives were found to be 15.0-18.9 and 10.2-12.1 days, respectively. CONCLUSION: Residual concentrations of the tested pesticides in the studied crop decreased, but those in the dried samples appeared to have increased. In addition, processing factor and half life were constant regardless of spraying times.

Nutrients and hormone levels of dried pig placenta were studied. Placentas were freeze-dried (FD), oven-dried at 60 (OD-60), and 90$^{\circ}C$ (OD-90) and then crushed by a blender into small pieces. FD and OD-60 pig placenta had a higher moisture content than did OD-90, with no difference between FD and OD-60. There were no large differences in compositions of crude protein, crude fat, and crude ash of dried placenta among the treatments and the contents of K, Fe, and ${\alpha}$-tocopherol were highest in FD (p<0.05). Glutamine and glycine were the most abundant amino acids in all dried placenta and tyrosine was highly retained in FD placenta, compared with OD (p<0.05). Estradiol was the major sex hormone, followed by progesterone and testosterone in all dried placentas. Antibiotics including amoxicillin, sulfamethazine, tylosin, and chlorotetracyclin were not detected from the pig placentas tested. These results demonstrate that placenta is a good biomaterial with high nutritional quality, and that freeze drying is superior to oven drying for processing pig placenta.

Background: Agricultural handle equipment is present on all production areas' farms. They are handy and portable; however, excessive use can lead to acute traumas or accidental injuries. Repetitive movements, awkward postures, and hand-arm vibrations predispose them to pain and work-related musculoskeletal disorders. The purpose of this study was to observe the interaction of handle equipment in terms of electromyographic activity and analyze the postural work-related alterations. Materials and methods: Twenty male agricultural operators, mean age 24±1.54 years, underwent the electromyographic analysis testing their muscular activities with a brushcutter, electric saw, and hedge trimmer in four different test conditions. Results: The brushcutter proved to be the agricultural handle equipment with the higher mean frequency (3.37±0.38 Hz) and root mean square (5.25±1.24 ms^-2). Furthermore, the digital postural analysis showed a general asymmetry of the main arm and the respective side of the trunk. The head resulted right inclined in the anterior frontal plane by 5.7°±1.2°; the right scapula lower than the left in the posterior frontal plane (8.5°±1.8°), and a working trunk inclination of 34.15°±5.7°. Conclusions: Vibrations of handle equipment and awkward working postures represent a risk for agricultural operators. Preventive measures are required to avoid young operators from experiencing musculoskeletal disorders all lifelong.
