팽이버섯 재배사의 Listera속 미생물 살균을 위하여 공기 살균 장치가 부착된 파일럿 버섯 재배사를 개발하여 물리적, 화학적 살균처리에 대한 살균 효과 검증실험을 수행하였다. 파일럿 버섯 재배사의 내부 온도는 상부 6.62˚C±0.30, 중간 6.46˚C±0.24, 하부 6.48˚C±0.25, 습도 는 79.97%±4.42, 79.43%±4.06, 79.94±4.30%로 설정 온도 6.5˚C, 상대습도 75%에 근사하게 제어되었다. 공기 살균 장치 적용에 적합한 팽이버섯 재배단계는 생육단계 조건인 온도 6.5~8.5˚C, 습도 70~80% 범위였고 유사 조건에서 이온 클러스터 발생기의 오존 발생농도는 160 ppb 수준으로 나타났다. 물리적 살균처리 후 Listeria innocua 의 생존율은 이온클러스터 살균의 경우 0.1~0.9%, UV공 기 살균은 9.3~10.6%로 나타났고, 화학적 살균처리인 75% 에탄올과 3% 유기산 수용액 처리구에서는 모두 사멸하는 것으로 나타났다. 소재에 대한 Listeria innocua 생존율은 금속시편의 경우 9.3~10.6%, 플라스틱 권지 9.9~16.2%로 나타났는데, 특히 권지의 거친면에서 생존율이 높게 나타났다. 본 연구 결과에 따르면 버섯 재배사의 Listeria균 발생을 억제하기 위해서 금속 소재로 구성된 재배사 벽면과 재배 선반에 대해서는 이온클러스터 공기 살균처리가 노동력을 절감하면서 살균 가능한 방법이며, 플라스틱 재질의 권지의 경우 화학적 살균처리가 효과적 인 것으로 나타났다.

The Agriculture, Forestry and Fisheries Research Council within the Ministry of Agriculture, Forestry and Fisheries looks over the Agriculture, Forestry, and Fisheries Research and Development Project. Every five years, it revises the Agriculture, Forestry and Fisheries Research Basic Plan. Based on the information above, the following suggestions are made to implement domestic research projects. First, the strategic planning and promotion of research and development projects are needed to achieve the goals of the country and agricultural policy. Second, it is necessary to break up and diversify research assignments so that the project implementation reflects the trend of the time. Third, there is a need to develop a research partnership that strengthens cooperation among industry, academia, government, and research institutes to utilize technology seeds from fields other than agriculture. Fourth, it is necessary to improve field demonstration research projects where central and local research institutes, universities, private companies, agricultural cooperation, and farmers can participate. Fifth, follow-ups should be conducted at the end of research to advance research implementation systems. Finally, there is a need to build a new dissemination system which includes research results and policy.

The Japanese government, on the basis of the Food, Agriculture and Rural Areas Basic Act, announced the 4th Basic Plan for Food, Agriculture and Rural areas, at the same time the third Basic Plan for Agriculture, Forestry and Fisheries Research in March 2015. The Basic Plan is configured as improvement of food self-sufficiency rate, a stable food supply, agricultural maintenance and development, rural promotion. The new target for the calorie-based food self-sufficiency ratio has been lowered from the previous 50 percent by 2020 to 45 percent by 2025. The production target for table rice has been lowered, but production targets for rice for flour and rice for feed have been raised significantly - five times and 10 times the more than current production by 2025, respectively. The 4th Basic Plan included the important measures of 24 and the details practice challenges of 50 should be intensively promoted for the next five years. The new Research Basic Plan set 21 key targets research and development to solve problems promptly faced by producers with the aim of increasing income in agriculture and rural communities and 11 priority targets research and development to be steadily promoted under medium- to long-term strategy. In addition, it announced the necessary measures of 10 at three areas in order to promote more efficiency and effective in the Agriculture, Forestry and Fisheries Research. In Korea, it refers to the announcement contents of Japan where there is a need to formulate a development plan for Agriculture, Rural Areas and Food Industry Development Plan that meets the Korean situation.

This study was carried out to evaluate the proximate contents and compositions of amino acids and fatty acids in Korean 6 dent, 2 intermediate, and 3 semiflint maize (Zea mays L.) hybrids. The protein content of 11 Korean maize hybrids ranged from 9.0% (Pyeonggangok) to 11.5% (Jangdaok). The crude fat content varied from 4.0% (Pyeonggangok and Yanganok) to 5.6% (Kwangpyeongok), and the crude ash content was 1.3 (Jangdaok) ~ 1.6% (Cheonganok). Total starch contents of maize hybrids were determined in the range of 51.4% (Jangdaok) to 70.9% (Cheonganok). Major amino acid in maize varieties were glutamic acid (27.28~28.68%) and followed by proline, alanine, and aspartic acid. Fatty acid were mainly composed of oleic acid (C18:1, 23.55~31.47%) and linoleic acid (C18:2, 47.55~56.64%) in maize hybrids. Cheonganok, Cheongdaok, and Kwangpyeongok had high oleic acid composition among Korean maize hybrids. Also, Gangdaok and Kwangpyeongok had high composition of saturated fatty acid. Because kernel composition affects maize quality, it is important data for the maize breeding program and food processing.

Experiments were conducted with aims to (1) estimate the biomass yield potential, (2) characterize the biomass and digestible dry matter production, and (3) reveal the characteristic seedling establishment of a whole crop rice variety, Nogyangbyeo, in dry- and wet-seeded rice. Maximum aboveground total biomass of Nogyangbyeo was 18 t ha-1 in dry-seeded rice and 20 t ha-1 in wet-seeded rice. Biomass yield potential of Nogyangbyeo was lower than that of Dasanbyeo. Comparatively, Nogyangbyeo was straw-dependent and Dasanbyeo was grain-dependent for biomass accumulation. Percentage of digestible dry matter (DDM) was higher in panicles than straw. Digestible dry matter yield was determined mainly by biomass yield rather than DDM percentage. Number of seedling establishment in Nogyangbyeo was 73m-2 in dry-seeded rice and 109m-2 in wet-seeded rice. Poor seedling establishment of dry-seeded Nogyangbyeo in the field condition was the result of low seed germination under low temperature and poor seedling emergence by deep sowing. Low seedling emergence rate of Nogyangbyeo was attributed mainly to slow elongation growth by slow leaf development and partly to mesocotyl and 1st internode lengths, not to genetically defined leaf length. The slow elongation growth of Nogyangbyeo was the same even in the high daily mean temperature of 24~circC . Results suggest DDM yield in rice can be improved simply by increasing biomass and whole crop rice varieties should be adaptable to direct-seeding.
