Several doses of butachlor ranged from 0 to 50 ai kg/ha were treated on the sandy soil and rice seedlings with 2~3 leaf stage were transplanted. There were no difference of injury by butachlor between 20℃ and 30℃. The optimum dose of butachlor to search the resistant varieties was estimated 30 to 40 ai kg/ha. Seventeen varieties among 392 rice varieties screened to butachlor were moderately resistant. The resistance of cultivar Kwanagbyeo and IR 667-98 were found to be controlled by a single recessive gene in the segregation of F₂ generation of cross combinations between the resistant and susceptible varieties.

이 연구는 남부지역 논에서 동계 사료맥류, 하계 조생종 벼, 추계 하파귀리 등 삼모작 재배기술을 확립하기 위해실시하였다. 월동 사료작물을 조생종 벼인 조평벼의 이앙시기에 맞춰 4월 30일 1차 수확한 처리구와 사료맥류의 수확기인 5월 30일에 수확한 처리구 모두 곡우호밀이 각각 생초수량 32.0톤/ha과 42.3톤/ha, 건물수량이 5.8톤/ha과 16.5톤/ha로 다른 작물에 비해 높은 수량을 보였다. 하계 조평벼는 5월 6일에 1차 이앙한 처리구보다 6월 4일에 2차 이앙한 처리구에서 등숙비율이 떨어지고 수량도 약 22% 감소하여 조기 이앙이 유리한 것으로 나타났다. 틈새작물로 재배한 하이스피드 귀리는 8월 28일에 1차 파종한 귀리는 10월 10일에 출수하였지만 9월 2일에 입모중으로 2차 파종한 귀리는 출수도 하지 못하였으며 1차 파종에 비해 건물수량과 TDN 수량 모두 50%를 못 미치는 결과를 나타내어 파종이 빠를수록 유리한 것을 알 수 있었다. 따라서 남부지역에서 삼모작을 하기 위해서는 호밀을 재배하여 4월 30일 전에 수확한 후 조평벼의 조기 이앙과 하이스피드 귀리의 적기 파종이 쌀 수량과 조사료 수량 확보에 유리한 것으로 사료되었다. This experiment was undertaken to develop triple cropping systems for winter cereal crops for forage, early maturing rice and oats, and to select a winter forage crop in order to determine rice transplanting time at paddy fields in the southern region. Also, the productivity and feed value of the resulting forage crops were examined. When winter cereal crops used for forages are first harvested at the early maturing rice transplanting period, and again harvested during the winter forage crop harvesting period, the fresh yield and dry matter yield of rye were 32.0, 42.3 ton/ha and 5.8, 16.5 ton/ha, respectively, demonstrating higher yields than other winter crops. The early maturing rice, 'Jopyeong', transplanted on June 4 had a lower percentage of ripened grain compared to those transplanted on May 6, and milled rice yield transplanted on June 4 was also decreased by 22%. Thus, the results showed that early transplanting was profitable. Regarding the oats grown during the fall cropping season, the heading date for the oats sown first was on October 10, but the heading was not observed in those sown later. Dry matter yield and TDN yield of the second sowing was less than 50% compared to the first. Consequently, rye may be the most suitable winter forage crop for triple cropping systems. Early transplanting of 'Jopyeong' after rye harvesting before April 30 in addition to timely sowing of oats in the fall season would be profitable for rice and forage production using triple cropping systems in the southern region.

이 연구는 비닐겹수 및 저장기간 따른 청보리 사일리지의 사료가치 및 사일리지 품질특성을 구명하고자 수행하였다. 조단백질 함량은 저장기간 모두 사일리지 제조 전에 비해 높아지는 경향을 보였고, 저장기간이 길어질수록 약간 높은 값을 보였지만 통계적인 유의성은 없었다. 비닐겹수에 따라서는 6겹 처리한 처리구가 4겹보다 높은 경향이었다. NDF와 ADF 함량은 저장기간 모두 사일리지 제조 전보다 높은 경향을 보였고(p<0.05), 저장기간에 따라서는 비슷한 값을 나타냈다. 비닐 겹수에 따라서는 6겹 처리한 처리구가 4겹보다 더 높은 값을 나타냈다. TDN 함량은 저장기간 모두 사일리지 제조 전보다 낮은 경향을 보였고, 저장기간에 따라서는 비슷한 값을 보였다. 비닐겹수에 따라서는 6겹에서 다소 낮은 값을 보였다. pH는 저장기간이 길어짐에 따라 낮아지는 경향을 보였고, 비닐겹수에 따라서는 6겹에서 4겹보다 낮은 값을 보였다. 유기산 함량에서는 저장기간이 길어짐에 따라 젖산함량은 약간 증가하는 경향을 보였고, 초산함량은 낮아지는 경향을 보였으며 낙산함량은 유의적으로 증가하는 경향을 보였다(p<0.05). 비닐겹수에 따라서는 6겹에서 4겹보다 높은 젖산함량과 낮은 낙산함량을 보였다(p<0.05). 따라서 청보리 사일리지는 장기저장을 할 경우에는 6겹으로 하는 것이 유리하고, 4겹으로 처리했을 경우 6개월 안에 사용하는 것이 유리하다고 판단된다. This study was undertaken to characterize feed value and silage quality according to storage period and film layers for whole-crop barley silage. The crude protein (CP) content increased in all silage during the storage periods compared to those before silage, this content slightly increased over the prolonged storage period but it was not significant (p>0.05). Depending on the film layers of silage, 6 layers were higher than 4 layers. The neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents also increased in all silage during storage periods compared to those before silage (P<0.05), but they were maintained at similar levels during the storage period. Depending on the film layers of silage, 6 layers were higher than 4 layers. The total digestible nutrients (TDN) content decreased in all silage during the storage periods. However, it was maintained at a similar level for the duration of each storage period. Depending on the film layers of silage, 6 layers were lower than 4 layers. The pH value was decreased during the prolonged storage period and depending on the film layers, 6 layers were lower than 4 layers. In the organic acid contents during the prolonged storage period, lactic acid increased, acetic acid was lower, and butyric acid was significantly higher (p<0.05). Depending on the film layers, 6 layers showed higher levels of lactic acid and lower levels of butyric acid (p<0.05). Therefore, these results showed that 6 layer wrapping was advantageous for long term storage of whole crop barley silage, while also indicating that it is desirable to use 4 layer wrapping within a six month period.

이 연구는 남부지역에서 동계 사료맥류, 하계 옥수수, 추계 하파귀리 등 삼모작 재배기술 확립하기 위해 옥수수의 앞그루에 적합한 사료용 맥류 맥종 선정과 더불어 옥수수 뒷그루로 귀리를 가을재배 시 생산성 및 사료가치를 검토하고자 실시하였다. 월동 사료작물을 옥수수 파종기에 맞춰 수확할 경우 호밀이 생초수량 32.0톤/ha, 건물수량 5.8톤/ha로 다른 작물에 비해 높은 수량을 보였다. 하계 사료용 옥수수는 생초수량으로 72.1톤/ha, 건물수량으로 20.2톤/ha 수확되었으며, 사료가치는 조단백질 함량이 7.4%, 가소화영양소 함량이 69.3%로 양호한 생육과 사료가치를 보였다. 가을재배용 귀리의 출수기는 10월 10일이었으며, 생초수량은 44.3톤/ha, 건물수량은 8.5톤/ha이었고, 사료가치는 조단백질이 11.3%, 가소화영양소 함량이 59.1%를 나타내었다. 따라서 남부지역에서 조사료 연중 생산을 위해 가을재배용 귀리의 도입으로 삼모작이 가능하며, 하계 옥수수의 최대 안전 생산을 위한 월동 사료작물은 호밀이 가장 유리한 것으로 사료되었다. Multiple cropping system is an important agricultural system in Korea, which is significant to increase forage yield and promote agricultural economic development. This experiment was carried out to develop triple cropping systems (winter cereals crop for forage - silage corn - summer oats) for maximum year-around forage production at paddy field in southern region. We also to select a winter forage crop to determine corn planting time, and to examine the forage productivity and feed value of summer cultivated oat, which was planted after corn cultivation. When winter cereal crops for forages are harvested in accordance with and corn planter, the fresh yield and dry matter yield of rye were 32.0 ton/ha and 5.8 ton/ha, respectively, showing higher yielding compared to other winter crops. Corn silage as summer crop was showed the fresh yield and dry matter yield of 72.1 ton/ha and 20.2 ton/ha, respectively. In the feed value, crude protein and TDN contents were 7.4% and 69.3%, respectively. They was showed higher productivity and feed value. The heading date of High-speed oat was October 10, and its fresh yield and dry matter yield were 37.6 ton/ha and 8.0 ton/ha, respectively. As a feed value, crude protein and TDN content was 11.4% and 59.1%, respectively. Therefore, triple cropping systems for the production of forage all throughout the year are possible with the introduction of summer oats in the southern region, and rye could be the most suitable winter forage crops for triple cropping systems.

To select the herbicide-tolerant callus variants, callus from the brown rice grain of Kwangmyongbyo and Minehikari was inoculated to the culture media containing several different dosages of 2,4-D-Lq(40%), Butachlor-Ec(33%), and Oxadiazon-Ec(12%). The pattern of callus survival percent was different in the two varieties. The limit dose of callus survival was different between the two varieties in 2,4-D and Butachlor, but it was same in Oxadiazon. The callus survival percent was not increased by the succeeding callus culture of the stepwise higher dosage of 2,4-D and Oxadiazon.

In this study, we conduct an empirical study to investigate the impact of the interdependence and trust between supplier and buyer on both their collaboration and supplier performance in automobile industry supply chain. The result shows that there is a positive relationship between the supplier`s dependence and trust on the buyer and their collaboration. Moreover, it shows that supplier`s dependence and trust on the buyer affects supplier performance through collaboration as a mediating effect. Therefore it is very important to notice that supplier and buyer in automobile industry should try to have a good collaborative relationship together in order to improve supplier performance.

開發途上國에 있어서의 多國籍企業에 관한 硏究

朴炯昊 全南大學校企業經營硏究所 1974 産業經濟硏究 Vol.1 No.1

The term “Multinational Coporation, ”a product of the 20th century, has been popularized in recent years, but that type of enterprise was already begun in the 1870s. In general, the developing countries want to develop their economy, but they are lacking in capital, technology, management skills, etc. On the other hand, the MC seeks for the maximization of profits with sufficient capital, advanced technology and management skills. Under the circumstances, the DCs and the MC can help each other for the mutual advantages. If so, the MC is bound to transfer its capital, technology, and management skills to the DCs and helps to make them develop the undeveloped economy. The MC engages in various international activities and operates plant in a number of countries with different political, economic, and cultural environments; it has a substantial financial commitment overseas and derives considerable profits from this business; and it has a worldwide perspective in marketing, investments, and other opportunies. It is natural that the investment effects of the MC should depend on the policies of host country and, in the end, upon all the negotiation abilities of both sides. Taking into consideration the investment motives and the nature of capital, the disadvantages of the MC on the DCs may be inevitable. Nevertheless, the host country should try to take measures in order to reduce those harms as far as possible. The first thing to be considered is to fortify its ability to absorb the foreign direct investment. And then, the MC ought to be advised to take self-restriction. In case this self-control is not effective, the host country can take the following restrictions; the determination of specific investment scope and definite investment ratios, management participation, the adoption of shrinking tariff system and “Calvo” clause, and so forth. Thirdly,, it is quite desirable that the host country makes an agreement, like GATT or IMF, with the investing country on a national basis. The agreement is related to the restriction of the MC activities which might hurt the economic and political sovereignty of the host country. In addition, we can consider the transnational international institution. But, in the near future, it seems to be difficult to expect its establishment. That is the reason why the world economy has not yet become a perfect economic community and each nation-state has not yet developed into a simple international nation institution. Those various restrictions might make the MC inactive temporarily and, in the long run, it will play the greater part in the world economy and, especially, in the DCs owing to its necessity and growth tendency. The MC will ultimately evolve into the “Transnational Enterprise” and, futhermore, the 21th century will be called “the century of the MC.”
