Apple is most favorable fruit in Korea, and apple farmland has been increased before and after the agreements of Uruguay Round and apple is considered as one of strategic agricultural products. Especially expansion of apple farmland is concentrated in Kyungpook region because of the suitable climate and its market share is about 70 percents in 1992. The marketing channels of apples of Kyungpook region are widely classified by merchant, agricultural or horticultural co-op and large scale farmer's. Among them market share of merchant's occupy over 65 percent. In marketing margins, commercial profit is higher than cost in total marketing margins and, assembler and retailer's margin is not less than wholesaler's. The fluctuation of the price of apple is high in year. The marketing problems of apples are several, first, complex marketing channels, secondly, the high percentage of market share by growing district assembler, thirdly, low rate of package and quality standardization, finally, concentration of shipment of apple because of the shortage of apple processing, storage and marketing facilities, of newly produced apples. In conclusion, to increase apple grower's income with the stabilization of supply and quality upgrade, the improvement measures of marketing system are as follows, first, government level's support in marketing facilities and mechanism, secondly, the increment of supply by grower's cooperatives, thirdly, the establishment of a serious of marketing system to increase the efficiency, fourthly, the establishment of cold-chain system and quality standardization of apple, finally, production of various kinds of apple processing goods.

Prebiotics are defined as "Nondigestible food ingredients that beneficially affect the host by selectively stimulating the growth and activity of bacteria in the intestine" and as defined improve host health. This study was carried out to investigate the effects of bifidobacteria (Bifidobacterium lactis BB12 and Bifidobacterium longum BB536) growth enhancer (BE0623) supplement as a prebiotic. The addition of BE0623, a growth promoting material for bifidobacteria, significantly increased bifidobacteria viable cells counts in fermented milk by about 45 to 75 times compared to the non-added control group. In addition, microscopic observation showed a significant effect on proliferation of bifidobacteria in fermented milk with added BE0623. The viable cell counts in bifidobacteria also increased roughly 102-fold compared to the control group (non-added BE0623) and was higher than that of commercial growth promoters. Each fraction obtained though the purification of BE0623 influenced the increase of bifidobacteria growth. Culturing bifidobacteria with a combination of fractions of BE0623 had a synergistic effect compared to culturing bifidobacteria with each fraction individually. When any of the fractions were not added, the effect of the growth enhancer on bifidobacteria was reduced. These results indicate that all fractions contain substances that promote the growth of bifidobacteria. Therefore, BE0623 is considered to be available as a growth promoting material for bifidobacterium.

It is remarkable that nuclear transfer using differentiated donor cells can produce physiologically normal cloned animals, but the process is inefficient and highly prone to epigenetic errors. Aberrant patterns of gene expression in clones contribute to the cumulative losses and abnormal phenotypes observed throughout development. Any long lasting effects from cloning, as revealed in some mouse studies, need to be comprehensively evaluated in cloned livestock. These issues raise animal welfare concerns that currently limit the acceptability and applicability of the technology. It is expected that improved reprogramming of the donor genome will increase cloning efficiencies realising a wide range of new agricultural and medical opportunities. Efficient cloning potentially enables rapid dissemination of elite genotypes from nucleus herds to commercial producers. Initial commercialization will, however, focus on producing small numbers of high value animals for natural breeding especially clones of progeny-tested sires, The continual advances in animal genomics towards the identification of genes that influence livestock production traits and human health increase the ability to genetically modify animals to enhance agricultural efficiency and produce superior quality food and biomedical products for niche markets. The potential opportunities in animal agriculture are more challenging than those in biomedicine as they require greater biological efficiency at reduced cost to be economically viable and because of the more difficult consumer acceptance issues. Nevertheless, cloning and transgenesis are being used together to increase the genetic merit of livestock; however, the integration of this technology into farming systems remains some distance in the future.

세계의 버섯 생산량은 매년 10-20% 증가해 왔으며 다품목화 되어가고 있다. 최근에는 큰느타리, 백령느타리 등이 새로운 품목으로 재배 면적이 증가하고 있다. 우리나라에서는 고려시대 저술한 김부식의 삼국사기(1145년)에 처음으로 금지(영지)와 서지가 기록되었고, 조선시대에는 16종류 이상의 농서 또는 의학서에서 버섯의 이용이 기록되었다. 상업적으로 이용되는 버섯으로는 지금까지 25종의 160품종이 보급되었다. 하지만 품종보호등록은 8품종만이 이루어져 아주 적은 편이다. 버섯산업이 1960년대 수출산업으로 육성되면서 자실체 생산량은 계속 증가해왔다. 2003년에는 181,828톤으로 생산가액 약 8,000억원을 능가할 것으로 추정된다. 버섯의 유효성분이 많이 알려지고 있는데 항균, 항염증, 항종양, 항바이러스, 항세균과 항기생물, 혈압조절, 심장혈관 장애 방지, 콜레스테롤 과소혈증과 지방과다 혈증 방지, 항당뇨, 면역조절, 강신장, 간장 독성 보호, 신경섬유 활성화, 생식력 증진의 효과가 있다. 따라서 버섯 의약품, 건강음료, 가공식품, Biotransformation에 의한 신기능성 제품 개발 등이 이루어지고 있다. 또한 버섯은 환경정화 기능이 뛰어나 환경오염 물질의 정화가 가능하며, 버섯재배후 배지를 이용하여 퇴비생산, 가축사료 생산에 이용된다. 한국의 버섯산업은 이미 가장 빨리 성장하는 농업 투자분야로 되었다. 그러나 버섯산업의 국제 경쟁력 강화를 위하여 국내고유의 품종개발에 의한 품종보호등록이 시급하다. 또한 저렴한 생산기술 개발과 유통구조 개선에 의한 생산량 조절이 이루어져야 버섯산업이 더욱 발전할 수 있을 것이다.

The quality of agricultural products is represented a degree of freshness and a special qualify that has a close relation to commercial value. To grade tomatoes, it used to nondestructive equipment of a charge-coupled device(CCD) camera and near-infrared(NIR) spectrum analysis method. The NIR spectrum analysis method is used to determine internal qualities such as a brix and an acidity. The CCD camera is used to measure external qualities like color and a size of tomatoes. This paper explaines the structure and movement of the automatic grade system and applies the algorithm for deformed tomtatoes and characteristics of tomatoes through image processing to the grade system.

The quality of agricultural products is represented a degree of freshness and a special quality related to a commercial value. To grade cucumber, the charge-coupled device(CCD) camera is only used to measure external qualities like color. size and degree of bended cucumber The processed area of the image replaces the weigh of cucumber. That means there is no longer used the weighing beams. The system consists of Image processing system and distributing system. This paper explains the structure and movement of the automatic grade system and applies the algorithm for deformed cucumber and characteristics of cucumber through image processing to the grade system.

Chemical analysis and optimum preparation conditions for fig jam were investigated. Soluble solids, acid content and vitamin C of fig was 12.20。Brix, 0.14% and 2.27 mg/100g, respectively. Carbohydrate in fig juice was consisted of 54.43% glucose and 44.53% fructose. Potassium content of fig was 178.0 mg/100g. Moisture content and total sugar of fig fruit was 88.35% and 9.47%. In preparation of fig jam, the addition of 0.2% Citrus natsudaidai juice and 0.5% C. lemon juice as acid source was the best in regard with color and flavor determined by sensory evaluation. The ratio of sucrose : honey : oligo sugar(70:20:10) was also the best in addition of sugar source 60%(w/w) in total. Fig jam prepared in this experiment was better than that of commercial products in sensory evaluation, and microbial growth of this product was not recognized for one month at 30$\^{C}$.

When the quality and cooking characteristics of wash free rice was compared with those of control milled rice during storage, smaller quality change during storage and more easy to cook was found in wash free rice than control. The wash free rice equipment manufactured in foreign country was carefully investigated and commercial wash free rice equipment with 1metric ton per hour capacity was made considering the characteristics of domestic rice cultivar. Modification of the equipment was made through the repeated field test, and the technique on wash free rice equipment was transferred to the RICETECH. These systems were manufactured in RICETECH will be exported of China next year.
