김성래,서종진,Kim, Sung-Lai,Seo, J.J. 한국학교수학회 2012 韓國學校數學會論文集 Vol.15 No.1

확률과 통계에서 사건의 독립 개념은 중요하고 유용한 역할을 한다. 본 논문에서는 중등 학교에서의 사건의 독립에 대하여 조사하고, 사건의 독립과 관련된 수학 개념을 어느 정도 알고 있는지 알아보았다. 그 결과 학생들은 사건의 독립과 관련된 하위 개념에 대한 이해가 부족하고, 사건의 독립과 관련된 개념들 간의 연결이 부분적으로 나타나 하위 개념과 상위 개념들 간의 연결이 잘 이루어 질 수 있도록 지도가 필요한 것으로 나타났다. Stochastic independence of events is not only important concept but useful role in statistics and probability. In this paper, we investigate and analyze the definition of stochastic independence used in the middle and high school mathematics education course. and We investigated that students know concept of independent events. As a result, students was a lack of understanding about the concepts associated with independence of events. and the connection between concepts associated with independent of events were partially. Also, Connections between lower-level concepts and high-level concepts can be done well so teaching-learning was needed.

This survey was conducted to secure a basic data for the effective training programs that might be an essential part of any successful mechanization of agriculture in Korea. Chung Nam provincial training center and 17 guidance offices with farm machinery training centers which were thought to be a medium level on their scale in whole country were selected in the survey on its training accomplishments, stafts, facilities, schedule and number of trainees at one time or in a class. The results and recommendations from this survey were as follows; To enhance the effect of farm machinery training, it was absolutely necessary for city or county training center to complement its facilities and equipments. It might be desirable that instructors of each training center should be the one educated or highly trained in the institution of farm machinery, and that the number of technical assistants should be increased and their present part time working condition should be changed to full-time status. It was recommended that training for farmers should be scheduled during off-season so that farmers could participate in the training couses, and that the number of trainees in a class should be reduced to about 10 trainees, which was approximately a fourth of the present situation.

Objectives : The purpose of this study is to observe the anti-oxidative effects of electroacupuncture at Taegye(KI3) in rats. Methods : The methods are measures of experimental items including change of body weight, relative liver weight, level of albumin, total bilirubin, LDL-cholesterol, LDH, GOT and GPT in blood serum, level of SOD, GSH, catalase, NO and MDA concentration in liver, histological change of liver. Results : 1. The KI3-EA group lost weight in the beginning, and gained it gradually. 2. The liver ratio of the KI3-EA group increased compared to the holder group, without any statistical significance. 3. The SOD activity, Glutathione concentration, and Catalase concentration increased, and the NO concentration and MDA concentration decreased in the KI3-EA group significantly, compared to the holder group. 4. KI3-EA group had more similar density to the normal group, than the holder group. Conclusion : The electroacupuncture application on KI3 has anti-oxidation effect, by improving the body defence against the oxidation stress- induced cytotoxicity, and by supressing the oxidative liver damage.

Since most farmers breeding livestocks in Korea is depended on imported feeds, the rate of selfsupplying feeds is very important for a stable development of farmers. 'Therefore, it is considered necessary to increase the rate of self-supplying feeds. In this study, performance tests were carried out with barley and forage to find the design's parameters of hammer for a small size hammer mill which can be driven by 3.7-7.5 kW power tiller being used by most farmers. The revolution speed of hammer mill was 3000 rpm, widths of hammer were 20mm, 30mm, 40mm, and the levels of thickness of hammer were 2mm, 4mm and 6mm. Experimental materials used were barley and forage and screen openings for barley was 4.76mm, and 3.18mm for forage. The study results can be summarized as follows; 1. Results of grinding tests showed that particle sizes were 478-774 microns for barley and 350-434 microns for forage. They were decreased according to the increasing thickness and width of hammer. 2. Fineness modulus of grinded materials were 3.07-3.62 for barley and 2.69-2.93 for forage. They were inversely proportional to thickness and width of hammer. 3. The required power for grinding was 3.8-5.0kW for barley and 0.9-1.4 kW for forage. The thickness of hammer was more important for less power requirement than width of hammer. 4. Grinding performance of a small size hammer mill was 99-170kg/kWh for barley and 11-21kg/kWh for forage. The thickness of hammer was an important factor for grinding performance, and inversely proportional to grinding performance. For about 3.2 of fineness modulus, 4mm thickness was the best, and an optimum width of hammer was 30mm for a small size hammer mill.

This study was conducted to obtain basic data for the design of cooling system by the test of engine performance of the power tiller being used widely in the rural area. Among the various factors affecting engine performance, the flow rate of cooling water was considered as the major factor in this study. Motoring loss, output, fuel consumption ratio, torque, heat absorption of cooling water, and thermal efficiency were measured and analyzed based on three flow rates of cooling water such as 15, 20, and 25ℓ/min. The results obtained were as follows 1. Motoring loss of the engine was 1.371㎾ at 2,200 rpm.. and mechanical efficiency was 79.1 % at rated output level. 2. Output power of the engine increased with the flow rate of cooling water increased. 3. BSFC was 282,9g/㎾ h at the flow rate, of 20ℓ/min, and the temperature of cooling water at outlet was 80.9℃. 4. There was a little variation of torque of the engine depending on the flow rate of cooling water. 5. Absorption of heat by cooling water was increased with the increase of flow rate. 6. The highest thermal efficiency of 32.3% at the flow rate of 20ℓ/min was observed.

The single edged blade was efficient to reduce tilling torque requirement than the double edged blade as previous reported study. This study was carried out to find reducing effects of tilling torque requirement of single edged blade comparing to double edged one in according to wearing by tilling operation, The single and double edged rotary blades were attached on same rotary shaft, and tilling operation was done in hard glass land. The wearing weights of the blade were checked out each 3 hrs tilling operation, at same time, the tilling toruqe requirements were measured with soil bin system in laboratory. The results of the study were summarized as follows: 1. The edged blade shape was not changed during the tilling operation of the rotary blade. The single edged blade was saved 5-10% in the maximum tilling torque and 3-15% in the mean tilling torque than the double edged blade for total durable period. 2. Generally, the tilling torques according to operation were decreased until original shape was maintained, but it was increased after 12 hrs tilling operation, and the tip shape of rotary blade was changed seriously. It is noted that the tip shape of the rotary blade is another factor affecting tilling torque, it should be desirable to study on the rotary blade tip shape to reduce tilling torque requirement after changing its original shape with wearing.

Diesel engine being used on power tiller has over heating problem while running at the rated power range, The reason for overheating the engine is mainly owing to so small capacity of cooling system. This study was conducted to determine relatively optimum capacity of cooling system for the diesel engine. The results obtained are summarized as follows. 1. The capacity of cooling system for the diesel engine being used in the rural area was not sufficient to cool the engine at the rated power. 2. It is desirable that the cooling water flow rate was 12ℓ/min if we used supplementary pump for increasing the cooling efficiency. 3. As cooling water was circuited 12ℓ/min, highest temperature of cooling water was 91℃. This value is within 88℃±5℃ of SAE Standard criterion.
