On account of the development of the high speed internal combustion engines, several methods for increasing burning velocity has been investigated lately. Installation of a squash area on a cylinder head is one of the simple and practical method to induce the strong tubulant flow of air-fuel mixtureinto a combustion chamber. In this study, a four-stroke engine used for agricultural purpose was tested as an experimental model. A mathematical model of the squash velocity was derived, and also, several characteristics of the squash phenomena during the motoring of the engine used as a modelwere investigated. The results obtained were as follows: (1) Mathematical model of squash velocity was established and cheked (2) Squaash velocity and engine speed were found to be proportional to the squash area while they were inversely proportional to the squash width. (3) Squash velocity and crank angle at which the squash velocity become its peak were influenced by the magnitude of squash clearance: increase of squash clearance made squash velocity reduced acd made the peak of the squash velocity for from the top dead center and (4) When the squash area is divided in small areas baving unit width along the squash section, squash velocity at each unit width was proportional to the magnitude of the squash distance covered by the unit width.

This paper aims to study the variability of interlanguage for Korean students. First, in order to explore whether there is variability in EFL learner language the 149 middle school students are assigned to do three language tasks - grammar test, cloze test and translation into English, Three kinds of interlanguage from three tasks show different accuracy levels of grammatical morphemes. Therefore we come to know that the variability in EFL learner language is caused by tasks' property. The second purpose is to figure out the relation between learning styles and the variability of interlanguage. The Korean learners who study English in formal classroom use individual learning methods or skills. In this research, the 149 students were asked to respond to the questionnaire to identify their teaming style preferences. This paper describes the results of the questionnaire and correlations between the tasks and learning styles. Each loaming style has different effect on the tasks. This indicates that learning styles cause variability in interlanguage.

It seems imperative to study learner language or interlanguage to get information about language acquisition. Interlanguage reveals itself systematic and also consists of variable aspects. L2 learners produce transitional constructions in the process of second language acquisition. The constructions can be ungrammatical and include many errors in the view of target language. However, it is seen to reflect the creative competence because L2 learners follow the same procedure as that of native speakers. On the other hand, aspects of variability are found in the interlanguage of L2 learners. For example, the accuracy of grammatical forms varies according to the language task. This variation is due to the attribute of each task. Also, such environments as classroom or teaching style affect use of language for the L2 learners. In addition, it is controversial that language users possess two kinds of knowledge: explicit knowledge and implicit knowledge. Therefore, the types of knowledge are considered to be at the base of leamers' output form. Although L2 learners follow the same developmental sequence despite their various L1 background, their acquisition order of grammatical forms varies in the way of interlangluage elicitation. Finally, whether learners experience the negotiated interaction or not could affect the formation of interlanguage because interaction is essential to language acquisition. The types of language activities like the two-way information gap task give learners more opportunities of interaction than others. This research proposes that various aspects of interlanguage should be examined more carefully in order to understand language acquisition further.

慶北地方의 動力耕耘機 調査 分析

This survey was crried out to investigate the crruent status of power tiller utilization in Gyeongbuk area. Basic information invesitgated from the gurvey will play important role in planning the farm mechanization program. Five areas including Sangju-Gun, Gumneung-Gun, Seongju-Gun, Gyeongsan-Gun, and Euiseong-Gun, were selected as survey areas. Crop farms were selected from the first 3 Guns out of 5 Guns listed above, and orchard farms from the rest of sample reas. Ten farms were taken from each Gun as survey farms. The diffusion rate of power tillers of these selected Guns was relatively higher than the other Guns in Kyeongbuk area. Obtained results are summarized as follows; 1. The annual hours of the power tiller utilization were 364.5 for the crop farms, and 364 for the orchard farms. The percentages of custom works were 42.7% for the crop farm, and 29.0% for the orchard farm(36% in average). This result may imply that the rate of domestic use of a power tiller was high. From the point of view based upon the results shown above, it would be necessary to develop various new attachments of the machine, and to supply low capacity power tillers suitable for domestic use in order to increase hours of annual utilization. 2. The percentages distribution by operations of a power tiller were; (1) for the crop farms: transporting, 30.8%; pumping, 27.6%; threshing, 19.2%; rotary tillage, 11.3%; ploughing, 7.9%; and weed and pest control, 3.2%. (2) for the orchard farms: transporting, 31%; pumping, 26.3%; weed and pest control, 13.1%; ploughing, 10.4%; threshing, 9.5%; and rotary tillage, 9.4%. The high percentage of pumping operation was attributable to the severe drought in Gyeongbuk area in 1977. 3. Monthly hours of power tiller use from January to March was very low. Monthly hours of utilization began to increase from April until it was get to its peak in June. And then, both in August and October, the peaks were appeared again. The appearence of peak in August was caused by the frequent pumping operations to protect the severe drought damage. 4. The effective ploughing capacities were 6.2a/hr for a 8PSkerosene tiller, 7.3a/hr for a 8PSdiesel and 10PSkerosene tillers. For rotary tillage, 12a/hr for a8PSand a 10PS kerosene tillers, and 10a/hr for a 8PSdiesel tiller. Capacity difference of rotary tillage between kerosene and diesel tillers was caused by their difference of weights. 5. The fuel consumption rates of power tillers with kerosene engines were 247.3g/hr.PS for a 8PS engine and 240.9g/hr.PS for a 10PS engine. In case of power tillers with diesel engines, the fuel consumption rates were 183.8g/hr.PS for a 8PS engine, and 183.6g/hr.PS for a 10PS engine. 6. The frequencies of causes of breakdown of power tillers were: lack of skill in machine operation, 38%; out of order 30%; and poor conditon of machine, 26%. It was necessary to strengthen the technical training for the operator to improve the skill of machine operation. The most frequent breakdown part of the power tiller was engine, and next, body and machine attachments in order. 7. The annual repair cost for a power tiller which was purchased within 7 years was 20,826 Won. The ratio of annual repair cost to the average cost of purchase was 4.1%. And the total repair rate was 0.29. 8. Fuel cost per 100 hours operation of a 8PS kerosene tiller was 60% higher than that of a 8PS diesel tiller. And for 10PS tillers, the fuel cost for a kerosene tiller was 58% higher than that of a diesel. 9. Annusl operating cost was 187,781 Won (fixed cost 113,776 Won, variable cost 74,005 Won) for the crop farm, and 185,327 Won (fixed cost 113,058 Won, variable cost 72,269 Won) for the orchard farm. 10. The annual incomes from custom work per power tiller were 164,039Won for the crop farm, and 103,155 Won for the orchard farm.
