본 연구에서는 가공용 쌀 이용성 향상을 위한 쌀 가공 제품개발과 쌀 생면 제조 기술 확보를 위해 반응표면분석법을 이용하여 글루텐 프리 쌀 우동의 주원료인 쌀가루, 변성전분(아세틸아디핀산이전분), 트레할로스의 함량에 따른 글루텐 프리 쌀 우동의 품질에 미치는 영향을 분석하고 제조 배합비를 Box-Behnken법을 이용하여 최적화하였다. 반응모형에서 쌀가루 함량이 높을수록 수분흡수율, 부피, 황색도, 탄성, 검성, 씹힘성, 응집성이 증가하였으며 변성전분의 함량이 적을수록 황색도, 탄성이 높았다. 수분함량, 명도, 황색도는 linear 모델로 결정되었으며 p-value는 <0.0001, 0.0113, 0.0214로 유의적 차이를 보였다. 글루텐 프리 쌀 우동 주원료의 배합비는 트레할로스의 첨가 없이 쌀가루 60 g, 변성전분 18.81 g 사용하는 것이 바람직한 것으로 나타났다. 반응표면 분석법을 통한 최적 배합비에 따라 글루텐 프리 쌀 우동을 제조한 결과 백색도는 73.09, 수분 흡수율은 59.73%, 부피 32.61 mL, 탁도 0.44, 조리손실율 5.74%, 용출고형분 함량은 1.86%였다. 이 연구 결과는 글루텐 프리 쌀 우동 제조에 기초자료로 제공되어 향후 제품 개발에 도움이 될 것으로 여겨진다.

The genomes of Arabidopsis and rice have been fully sequenced. Genomic sequencing provides global information about genome structure and organization. A comprehensive research account of our recent studies conducted on genome painting, comparative genomics and genome fusion is provided in order to project the prospects of plant cytogenetic research in post-genomics era. Genome analysis by GISH using genome painting is demonstrated as an excellent means suitable for visualization of a whole genome, since total genomic DNA representing the overall molecular composition of the genome is used as a probe. FISH on extended DNA fibers has been developed for high-resolution FISH and has contributed to determining the copy number and order of genes. We have also mapped a number of genes involving starch synthesis on wheat chromosomes by FISH and compared the position of these genes on linkage map of rice. Macro synteny between wheat and rice can be observed by comparing the location of these genes in spite of the fact that the size of DNA per chromosome differs by 20 fold in two. Moreover, to approach our goal towards making bread and udon noodles from rice flour in future by incorporating bread making and the noodle qualifies in rice, we have been successful in introducing large genomic DNA fragments containing agronomically important genes of wheat into a rice by successive introduction of large insert BAC clones, there by expanding genetic variability in rice. We call this method genome fusion.

To provide rice products in substituted for wheat flour and wheat products in elementary school foodservice, the survey for nutritionist in elementary school was accomplished from November 3rd to 8th, 2012 in Gwangju and Jeonnam area, and obtained 83 and 95 copies from Gwangju and Jeonnam, respectively. Most nutritionists were graduated from universities and had careers longer than 15 years. The nutritionists (56.7%) had worked at the schools where food allergy students were enrolled. The consumption of wheat flours per one student per month was 677.8 g in Gwangju and 707.4 g in Jeonnam. Udon and Jajangmyeon were more popular wheat products. Nutritionist agreed positively that rice products instead of wheat products were possible to use for meal menu (73.5% in Gwangju and 61.1% in Jeonnam). The frequent use of rice products was tteokbokkitteok, because of students' preference. The rice bread and tteokguktteok were preferred significantly higher in Jeonnam than in Gwangju. The advantages of rice products which perceived by nutritionists were benefits for health, digestive easily, and high nutritious, but their disadvantages were hard-to-find and expensive. The nutritional values of rice and recipes for cooking rice products were required as educational program for increasing consumption of rice products. Demonstration for rice cooking methods was selected most popular program. The application of rice products for school foodservice was preferred to Jeonnam compared to Gwangju (p<0.001). As a consequence, the nutritionists working in elementary school in Gwangju and Jeonnam area have positive thought about using rice products in school foodservice, if educational program of school foodservice menu using rice products should be demonstrated them.

Lao-native beef cattle are primarily Bos indicus, and most ruminant production in Laos is still dominated by small-scale or backyard producers that use traditional practices, resulting in low productivity. The cattle herd size in Laos has grown by an average of 5 percent per year from 1.52 million in 2010/11 to 1.81 million in 2014/15. In 2016, the Laos cattle population was 1.88 million head, with smallholder farmers representing 98% of production despite efforts by the Laos government to develop commercial-scale farms. There were 170 commercial cattle farms in 2016, with 56 percent in the Central region of Laos. Although, overall, ruminant meat production has tended to increase but with consumption at 7.29 kg/capita/yr in 2013, it remains insufficient to meet demand. Crop residues and agro-industrial by-products used in ruminant diets include rice straw, cassava pulp and wet brewers' grains as roughage, energy and protein sources, respectively. The Belt and Road Initiative proposed by China in 2013 will connect China closely with all countries in Southeast Asia. This initiative will change landlocked Laos to land linked for investors who will benefit from convenient transport at a lower cost, promoting agricultural production in Laos.
