  • Many problems were found out the remarkable unbalance between paddy fields and up-land areas, or between plain and mountainous areas, unreasonable establishing of land consolidaton boundaries without consideration of rural development, lower leverl of construction technology of the roads and canals for agricultral use ad operation and maintenance of them by human power far apart from the ages of high technology, high information and free internationalisation, and too slow progress to overcome the weak agricultural circumstances etc. through the survey in the past executed land consolidation projects. The basic ways for solution of these problems for propulsion of land consolidation project through investigation are summarized as follows : 1. Land consolidation project should be executed to the direction of balanced regional development, laying stress on the upland and mountainous areas in order to carry out the agriculture effectively. 2. the acreage of land consolidation project to be conducted anually should be increased to overcome the serious underdeveloped agricultural development. 3. It should be developed to the way in accordance with the order of land use from the view point of rural integral development including the rural readjustment. 4. The level of the structures of road and canal, the size of standard lot and the grouping of land substitution should be to incraese the productivity of land and labour more than ever and reached to a degree in cope with the age of industrialization, information and free internationalisation. 5. The level of the management of agricultural water use and the maintenace of the various facilities should be developed to be automatization, remote control, central control and information processing instead human work. 6. Land substitution should take a measure of grouping method in accordance with the agricultural plan and farming organization, which can overcome high industrialized society in place of the substition by origin land. 7. Land consolidation project should be planned in order to fulfil a conservative function of ecosystem and resources together with improvement of land and labour productivity.

  • 토지의 적성평가에 관한 지침에 따라 토지적성평가시 토지의 적성을 비교적 종합적으로 평가할 수 있으나, 기존지침의 평가지표 및 평가방법에 한계가 있다고 판단하였다. 현재 사용되고 있는 기본지표가 지역의 다양한 특성을 제대로 반영하기에는 한계가 있기 때문에 지역 특성을 반영할 수 있는 평가지표 및 평가방법이 필요한다고 보고 있다. 이러한 토지적성평가의 한계를 타개하기 토지적성평가시 새로운 지표로평가지표를 대체하였을 때 변화되는 적성등급까지 분석하는 실증적 연구이다. 이 연구에서는 관리지역 경계부 임야지역이 합리적인 평가가 이루어지는가를 확인하고, 토지의 적성평가에 관한 지침에 따른 관리지역 경계부 임야지역의 합리적인 평가방법을 확인하였다. 토지적성평가에 지역특성을 반영하기 위한 대체지표를 추가 하거나, 좀 더 효과적인 대체지표가 어떤 것인지를 확인하기 보다는 토지의 적성평가에 관한 지침에 따라 토지적성평가를 수행하였을 때, 관리지역 경계부 임야지역의 합리적인 평가방법을 제시하였다.

  • The purpose of this paper to study on measuring method in technical progress. Technology is combination method of raw material and capital, land, labour. The first step to technical Progress is COBB-DOUGLAS production function, so technical progresses are important role in economic growth and development. General production function from Y=f(K, L, T) and COBB-DOUGLAS production function Y=${AK^I}{L^b}$ is first condition. Technical progress is saving of production factor In capital saving, labour saving, neutral saving. Marred Hicks Robinson has Insist on technical progress by each view of production factor, but, what is most excellent measuring method of technical progress\ulcorner I : productivity index method. II : Gross Production function method. Productivity method used in every products level in weight values, gross method function method used in production factor attributed to products. Above two measuring method has delicate problem in each input factor, substitution relation and production factor simultaneously linked each others This basic problem based on technical progress is not solubable in this time.

  • 도시개발사업을 위한 타당성조사나 사업성 분석, 구역지정 제안 및 구역지정, 환지계획 작성 등을 위한 기존의 기초조사는 수치지도(1/1,000 또는 1/5,000) 및 이를 이용한 현장 조사, 인터넷 자료 및 문헌 등을 조사하는 방법에 의하여 자료를 분석하고 활용하고 있다. 도시개발사업의 시행방식인 사용 수용방식과 환지방식, 혼용방식 중 하나인 환지방식의 경우 본 사업 착수 전에 지형 및 건축물의 현황 등을 파악하여 환지 유형검토를 하여야 하나, 시행 전에 보안을 유지하면서 사전 자료를 확보하는데 한계가 있다. 일부 항공사진을 이용하여 기초조사를 실시하고 있으나, 이 역시 사진 촬영 시기에 따른 지형의 변화 및 건축물의 변경을 정확히 조사를 할 수 없는 단점이 있다. 기초조사를 수행하는 방법으로 본 연구에서 제시한 고해상의 융합된 영상을 기반으로 한 GIS를 구축하여 이용할 경우, 최근의 위성영상 확보 용이 및 대상 면적, 사용목적에 따른 해상도의 선택, 항공사진의 신규촬영대비 경제성, 위치정보의 확보에 따른 거리와 면적관측 가능 등의 장점과 기능이 추가되어 현재의 방법보다 더 정확한 자료에 의한 기초조사를 수행할 수 있을 것이다.

  • Security systems for inland cargo truck transportation are mostly limited to route tracking for safe and efficient transportation. With this route tracking system, the status of cargo trucks can be monitored easily within inland boundaries. In case of oil transportation by land, however, security systems ensuring transportation of a designated quantity of products have been subject to extensive research since thefts and substitution by a similar product in the transportation process have emerged as a social problem. Security devices installed in an oil tank truck must meet the explosion-proof performance standards and be applicable to varying types of trucks. Accordingly, a wireless electronic seal with RF communication functions is considered to be the most appropriate method, but e-seals on moving vehicles require such levels of performance and reliability that can overcome certain challenges including changing radio waves and topographical impediments. Considering these characteristics of oil tank trucks, this study proposes an stabilization method to enhance the RF communication performance of e-seals, based on radio simulation and experiment findings.

  • Background: An experiment was conducted in Vietnam to test the hypothesis that total dry matter (DM) intake and liveweight (LW) gain would increase in a curvilinear manner with increasing amounts of concentrate offered. Method: There were five treatments: a basal diet of Guinea grass fed at 1 % of LW and rice straw fed ad libitum (T0), or this diet supplemented with concentrate at 0.6 (T1), 1.2 (T2), 1.8 (T3), or 2.4 % of LW (T4). The concentrate comprised locally available ingredients, namely cassava chips, rice bran, crushed rice grain, fishmeal, salt, and urea, mixed manually. Results: Concentrate intake increased from T0 to T3, but there was no difference in concentrate intake between T3 and T4. Total feed intake increased in a curvilinear manner from 4.0 to 6.4 kg DM/d as the quantity of concentrate consumed increased. The substitution of concentrate for grass and rice straw increased with increasing consumption of concentrate and was as high as 0.49 kg DM reduction per kg of concentrate consumed. LW gain increased curvilinearly, with significant differences between T0 (0.092 kg/d), T1 (0.58 kg/d) and T2 (0.79 kg/d); but there were no significant differences in LW gain between T2, T3 (0.83 kg/d) and T4 (0.94 kg/d).With increasing amount of concentrate in the diet, the digestibilities of dry matter, organic matter, crude protein, and crude fat increased, but NDF digestibility decreased. Conclusion: Based on these results, young Vietnamese Brahman-cross growing cattle will respond to a locally-sourced concentrate mix offered at a level of up to 1.2 % of LW.
