본 연구에서는 E-nose 장비를 이용한 말고기와 소고기의 부위별 향기 특성을 확인하고, GC 분석을 통한 각 시료의 올레산 함량을 비교하여, 영양학적으로 높은 가치가 있으나 소비가 저조한 말고기 소비 시장에 대한 마육 가공식품의 대중화 가능성을 연구하였다. E-nose 분석 결과 말고기와 소고기의 향기의 종류에는 크게 차이가 없었다. 하지만, 부위별로 향기의 피크 최대치의 차이가 있어 향의 진하기에는 차이가 있는 것으로 나타났다. GC 분석 결과, 올레산 함량은 소고기가 높은 경향이었고, 말고기에서도 부위별로 유의한 차이가 있었다(p<0.05). 말의 부위별 차이에 대하여 향후 소와 말의 동일 부위별 지방산 비교 및 각 개체의 부위 간의 지방산 비교 연구가 필요하다. 본 연구 결과에서 소고기와 말고기의 육향은 차이가 없는 것으로 나타나, 비육마 가공식품은 소비자의 인식 변화 및 공급 유통망이 확보되면 제품 대중화가 가능할 것으로 판단된다.

Objective: The 3×3 factorial arrangement was used to investigate if either high water-soluble carbohydrates (WSC) cultivars or suitable time of day that the grass cut could improve nutrient values and in vitro fermentation characteristics. Methods: The 3 cultivars were mowed at 3 diurnal time points and included a benchmark WSC ryegrass cultivar 'Premium', and 2 high WSC cultivars AberAvon and AberMagic, which contained, on average, 157, 173, and 193 g/kg dry matter (DM) of WSC, and 36.0, 36.5, and 34.1 g/kg DM of N during 7th regrowth stage, respectively. The fermentation jars were run at 39℃ with gas production recorded and sampled at 2, 5, 8, 11, 14, 17, 22, 28, 36, and 48 h. The rumen liquid was collected from 3 rumen fistulated cows grazing on ryegrass pasture. Results: High WSC cultivars had significantly greater WSC content, in vitro DM digestibility (IVDMD) and total gas production (TGP), and lower lag time than Premium cultivar. Methane production for AberMagic cultivar containing lower N concentration was marginally lower than that for AberAvon and Premium cultivars. Grass cut at Noon or PM contained greater WSC concentration, IVDMD and TGP, and lower N and neutral detergent fiber (NDF) contents, but CH₄ production was also increased, compared to grass cut in AM. Meanwhile, the effects of diurnal cutting time were influenced by cultivars, such as in vitro CH₄ production for AberMagic was not affected by cutting time. The IVDMD and gas production per unit of DM incubated were positively related to WSC concentration, WSC/N and WSC/NDF, respectively, and negatively related to N and NDF concentrations. Conclusion: These results imply either grass cut in Noon or PM or high WSC cultivars could improve nutrient values, IVDMD and in vitro TGP, and that AberMagic cultivar has a slightly lower CH₄ production compared to AberAvon and Premium. Further study is necessary to determine whether the increase of CH₄ production response incurred by shifting from AM cutting to Noon and/or PM cutting could be compensated for by high daily gain from increased WSC concentration and DM digestibility.

From independent swab samples of the cloaca of indigenous gamecocks (CIG), anus of healthy baby goats (AHG), and vagina of goats (VG) originating from Phitsanulok, Thailand, a total of 263 isolates of lactic acid bacteria (LAB) were collected. Only three isolates, designated C707, G502, and V202, isolated from CIG, AHG, and VG, respectively, exhibited an excellent inhibitory zone diameter against foodborne pathogenic bacteria when evaluated by agar spot test. Isolates C707 and G502 were identified as Enterococcus faecium, whereas V202 was identified as Pediococcus acidilactici, based on 16S rRNA sequence analysis. When foodborne pathogenic bacteria were co-cultured with chosen LAB in mixed BHI-MRS broth at 39℃, their growth was suppressed. These LAB were found to be capable of surviving in simulated stomach conditions. Only the isolate G502 was able to survive in the conditions of simulated intestinal juice. This research suggests that selected LAB could be used as a food/feed supplement to reduce foodborne pathogenic bacteria and improve the safety of animal-based food or feed.

This paper aims to provide quite recent information on the organic industry in the U.S. Major focuses are on the development of cultivation and marketing of fresh and processed organic produce and foods, newly enforced certification program, consumers' purchasing behaviors toward organic foods, and social survey results administered to the organic farmers in the U.S. The U.S. recorded 8 billion dollars' sale of organic foods in 2000, which was the largest in the world and showed 23% growth compared to the previous year. Yet the organic industry is still a niche market, occupying merely 1.5% of total food sale amount. The natural foods markets have not been so concentrated in the U.S., but it is changing and a few wholesale mart such as Whole Foods is emerging. Recent introduction of new certification program provide unified and sole standard at the federal level to which every certifier needs to adjust itself in order to be acceredited by the government. According to a social survey, consumers purchase organic foods because they concern about health, they stick to their own modes of life favoring natural foods, and so on. Another social survey shows that most organic farmers sell their produces to wholesalers, distributers, or producer coop, and direct sale to visitors at their own farm comprises of about 8 percent of their organic land.

본 논문은 ICT 기술의 고도화를 통한 스마트 농업 확산 전략을 제시한다. 오늘날 세계는 환경 오염 문제와 지구 온난화로 전통 농업이 위협을 받고 있으며, 또한 저 출산 및 고령화에 따른 농업 종사자의 감소가 뚜렷하여 향후 식량 자원에 대한 사회적 문제가 예상된다. ICT 기술과 농업의 융합은 노동 집약적인 1차 산업이 아닌, 재배와 제조 및 서비스를 포함하는 새로운 페러다임을 제시하고 있다. 적은 노동력으로 양질의 식량을 안정적으로 공급할 수 있는 스마트팜 기술 보급이 시급한 실정이다. 본 논문에서는 현재 스마트팜 기술 현황을 살펴보고, 확산의 저해 요인을 분석하고 ICT 기술의 고도화를 통한 향후 스마트농업 발전 방향을 제시한다.

The effect of post-cut vanillin treatment at high concentrations on changes of quality and microorganism in fresh-cut apples was studied. Apples (Malus domestica Borkh. cv. Fuji) were sliced, treated by dipping in different vanillin solution, 0, 40, 80, and 120 mM, packed in polyethylene bag, and then stored for up to 3 weeks at $4^{\circ}C$. Changes in total aerobic bacteria, yeast and molds, browning, soluble solids, and titratable acidity during storage were investigated. Growth of total aerobic bacteria throughout storage was strongly inhibited by vanillin regardless of treatment concentrations. Growth of yeast and molds was inhibited by vanillin of all concentrations until 2 weeks of storage. Levels of browning index, soluble solids, and titratable acidity were not significant difference among the treatment conditions until 2 weeks of storage. However, when stored for 3 weeks, browning index increased more at 80 or 120 mM vanillin, while soluble solids and titratable acidity more be decreased by 120 mM vanillin as compared with other treatment conditions. These results show that the usage of vanillin in processing of fresh-cut apples had a limitation for maintaining quality.

Securing food safety, natural and social environmental protection, and activation of rural communities are some of challenging tasks for the 21st century. National consensus on agriculture as a basic and public industry would be needed to solve these challenging tasks. Agricultural policy and extension education should be focused on encouraging farmers to achieve better production and management by developing their motivation and ability. Systematic and organizational efforts to make a better environment for farming and farm management should be the major target of agricultural policy and extension services in the future. To meet changing needs of farmer, agricultural extension services should change programs, functions, information sources, and methods of delivery to adopt experiential learning for farmers. Functions for consultation, suggestion and organization should be extended and advisory services for farmers should be emphasized by providing extension education.
