The international grain price shows dramatic change, which results in the price change of Korean processed food. Recently, Korean government and consumers started discussing about the effects of change of international grain price on the processed food. However, few studies have analyzed this effects. The goal of this paper is to analyze the effects of price change of international grain, especially wheat, soybean, and sugarcane, on the processed food price in Korea. As the results of analysis, three findings are presented: First, the size and timelag of the effects of change of international grain price on the processed food price is different due to products, Second, there is the possibility that processed food price in Korea will increase, Third, Korean government has some methods to manage the price change of processed food, even though government cannot totally control the price.

Korean rice industry is facing new challenge. Nowadays, rice price is ever rising since last year. Difference between domestic price and international price is also ever decreasing and korean rice has chance to win over foreign rice because of better quality and low price. Now is the time to discuss on tariffication of rice import. Even if Korea follows modality of DDA, Korean rice market does not give in to foreign rice. On the other hand, Korean policy makers should make efforts to find way for grain sovereignty.

본 연구는 단기금리, 환율 및 국제유가가 국제곡물가격에 미치는 영향을 EGARCH-GED 모형을 이용하여 분석하였다. 국제곡물가격의 자체 이전 수익률 중 1개월 이전의 수익률은 대부분의 기간에서 국제곡물가격에 유의한 양의 영향을 미치는 것으로 나타났다. 전체분석기간에서는 환율만이 국제곡물가격에 유의한 영향을 미치는 것으로 나타났다. 환율상승기간에서는 경제변수 중 어느 것도 유의한 영향을 미치는 않는 것으로 나타난 반면, 환율하락기간에서는 유가만이 유의한 양의 영향을 미치는 것으로 나타났다. 그리고 금융위기 이전의 기간에서는 금리, 환율, 유가가 모두 유의한 영향을 미치지 않았으나, 금융위기 이후의 기간에서는 유가만 국제곡물가격에 유의한 영향을 미쳤다. 결국 국제곡물가격에 영향을 미치는 요인은 시간의 경과에 따라 변화되고 있는 것으로 나타났다.

This paper quantitatively analyzes the current status of North Korean consumer payment instruments through a questionnaire survey of 292 North Korean defectors. In the 2010s, it was found that the payment experience ratio of domestic currency cash and grain decreased, while the payment experience ratio of foreign currency cash increased. The use of foreign currency reached a stage where it was spread not only as a store of value but also as a medium of exchange. However, the most frequently used payment instrument by North Korean consumers was still domestic currency cash. By region, in inland urban areas both domestic currency cash and U.S. dollars are used and in the North Korea-China border region both domestic currency cash and Chinese yuan are used, while in inland rural areas dollarization does not occur because both domestic currency cash and grain are used. Meanwhile, despite the stable price trend during 2013-2019, the dollarization hysteresis effect is appearing, and both the purchasing power risk theory and the network externality theory are considered to have explanatory power for the cause. The results of this paper suggest that as dollarization is intensifying, it is expected that more costs such as shortages of commodities will be incurred than in the past if North Korea's de-dollarization policy is reimplemented. Also, in the case of domestic currency cards, which the North Korean authorities introduced in 2015 as part of a means of financial reform, this paper suggests that it may continue to be difficult for domestic currency cards to normalize official finance under the dollarization hysteresis.

Our self-sufficiency of food has become less than $30{\%}$ and our nation is highly dependant on world's grain market for food. which is unstable in long term due to the world population growth faster than food production. Therefore, it is a great possibility that food might become a political weapon by way of its global shortage. its purchasing difficulty in international free trade market. and the resultant price rising. Our maximal capability of food production has become the most outstanding problem in the dimension of future food security. It would be the utmost scheme for maximal production of food to realize the maximal utilization of arable land through the enlargement of sufficient farming land and the conversion of rotation system for the more grain production. Extensional enlargement of arable land can be positively executed through the development of farming land in domestic and abroad countries. The readjustment of arable land and the installation or irrigation and drainage system can enforce the farming basement for maximal utilization of arable land through the improved rotation between paddy and upland. The prevention policy against farming land encroachment should be strictly executed through grain production encouragement on resting or marginal lands and regulation of utilization conversion for the other than food production on high grade farming lands. It is also required urgently to develope high yielding and high quality varieties through advanced genetic technology for the improvement of unit area yield, especially of wheat, corn. and soybean we import in large quantity The maximal utilization of arable land for the highest production of food can be realized through rational rotation system, the most adaptable crop cultivation on the suitable land, and the most optimal fertilization through the GIS analysis of agricultural environment information on the basis of the computerized soil resource data on super detailed soil maps(1:5000) surveyed plot by plot of whole nation.

Self-sufficiency rate of food in South Korea is almost at the lowest level among OECD countries, and the decrease tend of farmland is expected to be continued. In this situation, Korea experienced a rapid change in the international price of grain due to changes in amount of grain production and food weaponization. It also started to reinforce the appropriateness of maintenance of farmland above certain standard. As one of policy means for this situation, this study selected "the use of idle farmland" as a subject, and started to consider the way to suggest the policy projects using idle farmland. The result of this study is summarized as follows. Firstly, this study defined the meaning of idle farmland, and set up the scope of idle farmland needed to this study. Secondly, this study analyzed the domestic major policy projects with prevention function of idle farmland as well as the policy projects related to idle farmland. It also investigated "recycling measures of idle farmland" that is recently promoted in Japan, and deducted the direction for developing a new model. Lastly, It suggested 9 policy project models that are finally able to use idle farmland. Suggested models are designed to access from various directions. This study suggested contents, entity, target and characteristics of projects in order to set up proper directions in promoting policy projects using idle farmland.

Many reclaimed tideland projects in Korea have been conducted to secure the food self-sufficiency. In fact, the domestic food self-sufficiency has been greatly improved and reclaimed tideland projects contribute to Korea's economic and social development directly or indirectly replacing agricultural lands from urbanization, industrialization. As result, current self-sufficiency of rice reach the demand(104.6%) while rate of upland crops has less than 30% of self-sufficiency rate and corn, wheat, soybeans, etc. are virtually dependent on imports. Domestic price of crop is expected to be unstable by trend of international grain prices. Therefore, developing reclaimed tidelands as upland which is originally constructed for paddy fields could be a good option to become steady in domestic crop market and dedicate to ensure a stable food security. The study to prepare measures for dealing with disasters in reclaimed tidelands of west coast district is required in order to utilize those sites for infra construction of multi-utilization in those sites and The result of flooding analysis in this study can suggest policy direction for practical utilization of reclaimed tidelands in yellow sea area.

Research on barley as an animal feed started some decades ago but its utilization in animal production has been limited to countries that grow the crop extensively. Corn has been the most popular energy feed in cattle rations, but the high price of corn and the decreased supply of the grain in the international market have shifted the focus of the animal industry to other cereal crops like barley. Studies have indicated that growth performance of cattle fed barley-based diets has been generally comparable with that of those fed corn-based diets, while results for cattle fed whole-crop barley silage have been more variable. Beef from cattle fed barley-based diets has proved to be as tender and as acceptable for taste as that from animals fed other finishing diets when compared at similar growth rates and degree of finish. The barley crop contains good amounts of antioxidants like 2"O-GIV isovitexin, so from the meat science point of view, a desirable influence of these components on meat quality traits such as meat color, oxidative stability and sensory characteristics might be expected. Furthermore, the effect of the distinctive fatty acid profile of beef fed from whole-crop barley silage on sensory traits is also an important subject to be elucidated. A lot of studies have been made over past decades on the effect of barley, and especially whole crop barley, on beef cattle production and meat quality, but these data have not been collectively documented in a review. The current review re-visits previous literature to underline the effects of barley in the diet on beef quality traits and to identify areas for further studies.

본 논문은 공급 업체(Supplier), 소매 업체(retailer) 및 고객(Cuistomer)으로 구성된 2 단계 공급망(Supply Chain)에서 소매 업체의 경제적 주문량(로트 크기)에 대한 문제를 분석하고자 한다. 이와 같은 2 단계 공급망에서 공급 업체는 경쟁 기업과의 가격 차별화 전략으로 소매 업체가 지불해야 할 상품 구입비용에 대해 일정 기간 지불 유예를 허용하기도 한다. 또한 식품, 곡물 등의 소비재의 경우 일반적으로 최종 고객의 수요는 소매 업체의 진열된 재고 수준에 따라 종속적으로 나타나는 것을 흔히 볼 수가 있다. 따라서 본 연구에서는 이와 같은 관점에서 공급업체가상품 구입비용에 대해 소매 업체에 일정 기간 지불 유예를 허용하는 경우에 고객의 수요가 소매 업체의 재고 수준에 크기에 따라 증가하는 함수라는 가정 하에 소매 업체의 재고 문제를 분석 해 보고자 한다. 공급 업체가 허용하는 지불 유예 기간이 소매 업체의 재고 정책에 미치는 영향을 분석하기 위하여 몇 가지 지불 유예 기간에 대한 소매 업체의 경제적 주문량을 결정 해 봄으로써 상품 구입비용에 대한 지불 유예 기간의 길이가 소매 업체의 재고 정책에 미치는 영향에 대하여 계량적으로 분석 해 보고자 한다.
