A computer simulation was carried out to investigate draft characteristics of Korean paddy field for obtaining the basic reference to the selection of optimum moldboard type suitable for Korean paddy field conditions. Cylindrical, cylindroidal, semihelical moldboard plows, and one type of oriental Janggi were used for simulation. A series of soil bin experiments was conducted to compare the experimental results with the predicted drafts from computer simulation using the cylindroidal moldboard plow. The computer model predicted draft force with 1~12% error at 12~16cm plowing depth which is the most conventional plowing depth in the rural area in Korea. Thus, the computer model was considered to be good enough for simulation. Due to the different plowing width of experimental plows, specific draft was selected for comparison by computer simulations. Specific draft of cylindrical moldboard plow was ranged from 3 to 6 N/$\textrm{cm}^2$ according to the soil conditions, plowing speed and plowing depth, 2.5~3.0 N/$\textrm{cm}^2$ for semihelical moldboard plow.

This study was conducted to analyze the storage and management status of major farm machinery, and to present the basic information for the construction of multipurpose storage housing suitable to the individual farmers by identifying current problems. The average farm area of the surveyed farmers was 4.25ha, which represents relatively higher than the average of whole country. The mechanization rate for paddy farming was 98%. so, the individual storage housing should be concentrated on the farm machinery utilized in paddy farming. The annual operating time for the seasonal farm machinery(such as combine and rice transplanter) were showed high difference between farmers and machines. For the rice transplanter, the highest portion of annual operation time was 1∼10 days as 71%, and for the combine, that was over 20 days as 36% and the second was 16∼20 days as 23%. The average difference in repairing cost for combine between the farmers with and without common storage housing was 100,000 won. The percent of storaging farm machinery in the open field for farmers without housing were 44% for power tiller, 16% for farm tractor, 21% for rice transplanter, 10% for combine. Each farmer had the individual temporary simple housing with various kinds and structure. Most of the farmers, 63.7%, want to use the farm machinery storage housing as multipurpose utilization. Twenty nine percent of farmers want to use the farm machinery storage housing any for storaging purpose. And, most farmers prefer near the farm house as suitable position of housing, and prefer the area of 132∼198㎡ for storage housing. The current problems on common storage housing were insufficient area(44.8%), no problem(29%) improper position, excessive construction cost, inconvenient entrance, etc.

Various definitions and terminology applied to measurement in analytical chemistry are not always consistent. But, internationally integrated terminology and interpretation of definitions play an essential role in analytical chemistry fields. The review in this paper focused on problems associated with terminology, definitions, statistical theories, and practical performance of calibration and validation.

정부가 일반 국민과 작물보호제를 포함한 여러가지 식품안전성에 대한 위험정보교환 기회를 많이 마련, 안전과 관련된 적극적인 홍보와 교육을 하고 식품안전정 내용을 초 중등교육의 교과내용에 포함시켜 체계적인 조기교육을 하는 것이 바람직하다고 본다.
