The purpose of this research paper is to examine, from an ethnological viewpoint, the traditional practice of using sacrificial game and domestic livestock as is often seen at communal rites in Korea. This paper also examine how the more convenient use of livestock sacrifice developed from that in which wild game were once offered, and how this change in the type of animals used affected the significance of the sacrifice. It also looks at how the use of animal sacrifice for ceremonies eventually influenced the practice of meat consumption on the part of the participants in their daily life, and how it contributed to the eventual establishment and development of livestock breeding for the purpose of meat consumption. The practice of catching wild game in the mountains for sacrificial purposes eventually gave way to the use of pasturage cattle, but it should be understood that these domesticated livestock were raised primarily for ceremonial rather than meat consumption purpose. When used for sacrifice, these cattle were not castrated, as is normally done when they are slaughtered for meat consumption, but it should not be assumed that this was done for purposes of simplification. In addition, not only rice farmers but also when enterpreneurs set up a new enterprise, animal sacrifice was viewed not only as a form of on-site purification of evil, but also served the dual purpose of enhancing their business through the traditional custom of serving meat to those invited guests in attendance. In the large-scale village communal rite of Hwaghae Province located in the northwestern part of Korea, animal sacrifice was carried out in the ritual for the Mountain God in a highly dramatic style, and suggests that it originated with the agrarian rites of the "fire-field" farmers of East Asia, which were utilized to foretell whether the coming year would be one of abundance or famine, and to the royal ceremony held on the 3rd day of the 3rd month of the lunar calendar, as well as that held for the God of the Mountains and Streams. The dramatic-style hunting rite, included in the large-scale communal ritual of Hwanghae Province mentioned previously, as well as in the Ritual of the Cow from Pyungsan, also located in Hwanghae Province, in which wild game were used as sacrifice, is significant in that it points up the changes that have occurred in ceremonial animal sacrifice. However, more research on ritualistic animal sacrifice is still called for in rites for good farming, fishing, and the variety of others that are held throughout Korea.

선진국들은 종자산업을 국가 신성장 동력산업으로 설정하여 정부차원의 지원을 강화하고 있으며, 글로벌 종자기업은 세계의 종자시장을 선점하기 위하여 종자개발분야에 막대한 예산을 투자하고 있으며, 우리나라도 2000년대 후반 들어 국내종자산업 발전을 위한 정책 추진을 통해 종자산업 육성을 위한 토대를 형성하고 있다. 본 논문에서는 국내외 종자시장 현황을 살펴보고 이에 따른 GSP사업의 역할에 대한 전망을 통해 GSP 사업 추진의 효율성을 제고해 보고자 한다. 세계 종자산업은 글로벌 거대 기업의 대형화로 인하여 독점체제를 형성하고 있어 상위 10개 종자기업이 전체 시장의 73%를 점유하고 있는 것으로 나타났다. 종자업체의 대형화는 종자선택에 대한 제약으로 인하여 가격상승을 불러일으키는 부작용을 초래할 것으로 보여진다. 국내 종자시장은 농업생산량 감소로 인하여 정체상태가 유지되고 있으며, 전반적인 국내 농업생산량의 축소에 따른 종자수요 감소로 인하여 국내 종자시장 규모의 정체와 업체의 영세성과 채소, 벼등 일부 특정품목에 대한 육종기술은 세계적인 수준이나 양배추, 파프리카 및 사료작물 등 글로벌 품종의 육종기술이 상대적으로 취약하고 국내 종자기업들의 신규 전문인력 채용은 거의 이루어지지 않고 있으며, 대학 등의 종자관련 전문인력 양성에 대한 인프라가 부족하여 우수한 육종 전문가 양성이 미흡한 실정이다. 따라서 종자산업은 농산업의 핵심으로 국가의 기간산업을 지탱하는 원천 산업으로서 국가정책적으로 우선순위가 매우 높은 만큼 미래성장 산업으로 정부의 지속적인 투자가 뒷받침되어야 할 것이다. 이에 대한 일환으로 GSP 사업을 추진을 2012년부터 야심차게 추진하고 있으며, 수출전략형 종자개발(10개 품목)과 수입대체 종자개발(10품목)을 통해 수출과 국내 종자자급율 확보를 목표로 종자관련 기업체와 대학 및 연구소의 우수한 전문인력이 투입되어 종자개발연구에 매진하고 있다. 우리나라 종자산업의 발전을 위해서는 GSP 사업의 우수한 성과가 반드시 도출되어야 할 것이며, 이를 위해서는 품종개발 단계외에 종자 수출에 대한 별도의 지원 프로그램 추진이 필요하다.

시판 증류주 13종을 선정하여 전자코, 전자혀를 이용한 향기패턴과 맛패턴을 분석하였다. 전자코 분석 결과, 원재료에 따라 증류주의 향기성분이 구분됨을 확인하였다. 원재료가 좁쌀인 증류주가 향기 성분이 가장 많으며 쌀의 함량이 적고 보리가 함유된 증류주가 향기성분이 가장 적었다. 또한 오크통에서 숙성시킨 원액을 100% 사용한 경우 향기성분이 뚜렷하게 구분됨을 보였다. 따라서 숙성재에 의해 증류주의 향기성분이 구분될 것으로 예측된다. 시판 증류주를 전자혀로 분석한 결과, 증류주는 단맛과 쓴맛 보다는 신맛, 감칠맛, 짠맛으로 시료간의 차이가 구분되었다. 본 연구를 통하여 전자코와 전자혀가 증류주 모니터링에 활용이 가능한지 여부를 확인하고 분석한 시판 증류주의 향미특성 결과를 추후 증류주 개발 및 품질관리에 이용하고자 한다.

Thailand is a country of native beef cattle resource farming. It has undergone rapid social and economic change in the past decade. Agricultural growth has been maintained by increasing the production of rice and cassava. Changing economic status also provides opportunities for beef cattle producers to meet increasing consumer demand for beef. Finishing beef cattle numbers in Thailand were about 1.0 M head in 2015. Beef produced in Thailand has exclusively been for domestic consumption. Only 1% of Thailand's beef cattle are for the premium market which is based on marbling score, 40% are sold into modern markets that consider muscling of cattle, and the remainder enter traditional markets. Cross-bred cattle for the premium market are raised within intensive systems. Most producers of premium beef are members of beef cooperatives, or have invested in their enterprises at high levels. Culled cow (native or cross-bred cattle) are mainly for small holder farm production. Malaysia, Indonesia, and other members of the Asian Economic Community (AEC) are set to become the largest beef market, which has been confirmed by 2015 through 2020 forecasts for consumption of beef that must increasingly be halal. These circumstances are likely to be challenging for beef producers in Thailand to gain a share of this market. Integration across all sectors involved in beef production in Thailand will be required.

Currently TMR feed produced in commercial plant is one of the major source to feed cattle for both beef and dairy farm. However, because of lack of cutting and mixing system for utilizing domestic produced firmly baled round roughage in commercial TMR plant, these commercial TMR feed can not satisfy to farmers both in quality and price points of view. In order to solve these problems, a farm group size TMR plant model was developed in this study. The model plant was consist of round bale receiving and cutting system, pneumatic conveying system for transfer the roughage which was cut at the cutter to TMR mixer through pneumatic conveyor, TMR mixer enable to soften the stiff rice strew and to mix with other ingredients, finished feed bin which can be transfer to either packing system or individual farm, packing system by tycon bag which contains 400 kg unit and bulk unloading system to individual farmer. Also, a simulation model ARENA was applied to the model system in order to evaluate and check the production rate in each unit process and operation rate of total system and to find out if there are any clogged unit system obstructing the smooth flow of the total process flow. Processing cycle for produce one batch of the model plant was less than 30 minutes. Thus, it will take less than four hours for producing 16 tons per day equivalent to 1,000 beef cattle's daily feed.

The purpose of this study is to establish the databases of pollutant sources and water quality measurement data by utilizing GIS, and making the user interface for the management of pollutant sources. Yeongsan Estuarine Lake was formed of a huge levee of 4.35 km constructed by an agricultural reclamation project. Water quality of the reservoir has been degraded gradually, which mainly attributes to increase of point and non-point source pollutant loads from the lake's watershed of 33,374.3 $\textrm{km}^2$ into it. Application of GIS to establishment of the database was researched of pint source such as domestic sewage, industrial wastewater, farm wastes, and fishery wastes, and non-pont source such as residence, rice and upland field, and forest runoffs of the watershed of the lake. NT Acr/Info and ArcView were mainly utilized for the database formation. Land use of the watershed using LANDSAT image data was analyzed for non-point source pollutant load estimation. Pollutant loads from the watershed into the reservoir were calculated using the GIS database and BOD, TN, TP load units of point and non-point sources. Total BOD, TN, TP loads into it reached approximately to 141, 715, 2,094 and 4,743 kg/day respectively. The loads can be used as input parameters for water quality predicting model of it. A user-friendly interface program was developed using Dialog Designer and Avenue Script of AcrView, which can perform spatial analysis of point and non-point sources, calculate pollutant inputs from the sources, update attribute data of them, delete and add point sources, identify locations and volumes of water treatment facilities, and examine water quality data of water sampling points.

왕겨를 탄소원으로 사용하여 증균 배양을 실시함으로써 국내 사찰에서 제조된 된장으로부터 xylan 분해능 우수한 균주를 분리하였다. 분리균 YB-1301은 DNA gyrase subunit B 유전자(gyrB)의 염기서열에 근거하여 Bacillus safensis로 동정되었다. B. safensis YB-1301을 밀기울 또는 여러 종류의 xylan들이 첨가된 배지에서 배양하였을 때 xylanase의 생산성이 급격하게 증가되었다. 특히 birchwood xylan이 첨가된 LB 배지에서 플라스크 배양을 하였을 때 최대 340 U/ml 이상의 xylanase 생산성을 보였다. Xylan이 첨가되지 않은 LB 배지에서는 매우 소량의 xylanase가 균의 성장과 연계되어 항시적으로 생산되지만, xylan이 첨가된 배지에서는 정지기 생육단계에서 xylanase의 생산이 크게 유도되었다. 더구나 xylanase 생합성은 가수분해되지 않은 xylan 보다 xylan의 효소적 가수분해 산물에 의해 더 빠르게 유도되었다. 또한 B. safensis YB-1301의 배양상등액에 존재하는 xylanase는 55℃와 pH 6.5−7.0의 반응조건에서 최대활성을 나타냈다.

The object of this experiment was to investigate the food habits of Korean native goats fed with various roughage sources. The experimental trials were conducted at Unbong Animal Genetic Resources Station in 2008. The experimental roughages include five sources and 25 species in all; grasses and legumes: 5 species (mixed grasses, orchardgrass, tall fescue, alfalfa, white clover), native grasses and weeds: 5 species (mixed native grasses, Miscanthus sinensis Anderss, Arundinella hirta (Thunb.) Tanaka, Barnyard grass, short awn, forage crops and straw: 5 species (barley + hairy vetch, wheat + hairy vetch, rye silage, barley silage, baled rice straw), browse and fallen leaves: 5 species (Mixed browse, Oriental white oak, Quercus serrta Thunb., Oriental cherry fallen leaves, Japanese chestnut fallen leaves), and imported hay and straw: 5 species(timothy hay, tall fescue straw, annual ryegrass straw, klinegrass hay, alfalfa hay). Ten Korean native goats were selected which had nearly the same body weight (average $24{\pm}2.8$ kg). The chemical composition and dry matter digestibility of each roughage source and species were significantly different at the sampling area, plant species, growth stages and cutting period (p<0.05). Among all the 25 species of roughages, the favorite intake species order by Korean native goat was observed like this: Quercus aliena, Querancas serrta Thunb and Mixed browse, which was a lower intake compared to other domestic herbivores. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. The Korean native goats ate more roughages which had low fibrous contents, but high dry matter digestibility. On the other hand, compared to each roughage source, total intake amount by Korean native goats was showed as browse and fallen leaves (33.1%) among trials roughage sources. Based on these results, the food habit of Korean native goats seems to be closer to the browser.

1. The field test of our experiment comparing the traditional syckle and the new manually pulled cutter showed that the working efficiency of the manually pulled cutter is about two times higher than that of the syckle. The operator can standerect while using the manually pulled cutter, thus reducing fatigue. Because of the reduction in body fatigue, the operator is able to work more total hours, making the manually pulled harvester three times more efficient than the syckle. 2. The optimum angle for the V-shaped cutter blade varies according to the number of the hiller, but in manufacturing the cutter, the range must be controlled between $35^{\circ}{\sim}45^{\circ}$. 3. The radius of curvature of the V-shaped blade is closely related to the blade angle. The best results were obtained when the radii of curvature were r=32cm with $35^{\circ}$ angle, r=153mm with $45^{\circ}$ angle, and r=220mm with $40^{\circ}$ angle. 4. The hardness distribution test of the blade showed great differences between foreign made and domestic made blades. The heat treatment method must be greatly improved for superior hardness distribution. 5. Although the efficiency of the manually pushed cutter is equal to that of the manually pulled cutter, the manually pushed cutter is not only more expensive to produce but also has a much more complicated structure than the manually pulled cutter. Because of our rural economic conditions, the power harvester which is utilized in foreign countries can not yet be introduced here. Thus, the manually pulled cutter should be popularized in our rural areas until economic conditions will allow us to introduce power harvesters. 6. The use of the manually pulled cutter will make it possible for an operator to harvest an area in only one-third of the time that it would take to harvest the same area with a traditional syckle, and it will make it possible for an operator to earn about 8,000 won for harvesting 10 Jung-bo: such benefits will help in increasing farm income and will contribute to farm modernization.
