The objective of this study is to present the method of improving the efficiency of the rural rice market by investigating rice variety chosen. post-harvest rice handling and sales activities of farmers. To achieve this research objective, a case study was conducted on the sample of 193 farms and 4 agricultural cooperatives located in 4 districts(myuns) of Kyungmnam area. The major findings of the study are as follows. 1. The willingness of farmers to produce a high-quality rice in terms of variety choice and post-harvest technology was not strong mainly because the government policy had not reflected quality in the purchase of rice. Labor shortage problem also made it difficult to produce a high-quality rice at the farm level. 2. Farmers were selling rice mostly during the harvest period due to the cash demand and commercial rice marketing activities were weak due to the large volume of the government's rice purchase. Therefore, farmers seemed to have trouble in finding an outlet to sell the rice. 3. The possibility of illegal rice marketing was very high due to the lack of standardization and grading of rice in rural areas. In spite of their crucial role in rice marketing. small-scale rice mills were engaged in excessive competition only to cause many problems. Rice marketing connection production area and consumption area directly without any involvement of wholeasler is very popular now, but it did not seem to contribute to the improvement of the rice marketing efficiency in terms of marketing cost. The reason is that the transactions are mostly dealt in a closed small-scale form. 4. Therefore, following measures are recommended to supply the high-quality rice, to prevent the illegal rice marketing, and thus to achieve the efficient rice marketing : First, integrated rice handling facilities should be constructed in rural areas; Second, a modernized rice mill with an economy of sacle should be formed by combing small-scale mills to guarantee the supply of high-quality rice. Also measures to force the quality control of rice in the mills are necessary. Third, packing and grading should be standardized. Fourth, the rice wholeasle market and the involvement of agricultural cooperatives in the rice marketing should be activated. Fifth, rice production system should incorporate the use of rice.

2014년 캔위성 경연대회가 미래창조과학부 주최, KAIST 인공위성연구센터가 주관으로 개최되었다. 본 논문은 슬기부 우수상 수상 팀 YYCS 의 캔위성의 설계 및 제작 과정과 결과 분석을 다루었다. 본 캔위성은 기본임무로 GPS 정보, 자세정보, 지상 이미지 정보를 송신하였으며, 확장 임무로 PWM 신호, Servo motor 와 태양 전지판을 이용한 전력 시스템을 구축, 내ㆍ외부의 온도를 측정 및 분석, 이중낙하산을 활용한 착륙시간의 확보, Sponge Structure 를 이용한 착륙 충격을 완화하는 등의 다양한 임무를 수행하였다. 캔위성 경연대회 임무 수행 결과 기본 임무와 확장 임무 모두 성공하였다. 2014 Korean CanSat Competition, hosted by Ministry of Science, ICT and Future Planning and SaTReC KAIST, was held. This study deals about CanSat design, manufacture process and result analysis implemented by Excellence Award winner in Division Seul-ki. CanSat"s primary missions are transmitting GPS, Satellite Attitude information and ground images. Extended missions are constructing electrical system by using PWM signal, Servo motors, and Solar array, measuring and analyzing CanSat"s inside and outside temperature, cushioning landing impact and Get landing time using a double parachute. Both primary and extended missions succeeded as a result of the performance.
