The purpose of this study is evaluate the direct payment program for rural landscape conservation and deduce facts to improve. This research is composed with a survey on local government officials and farmers joined this program, and used monitering in selected 41 zones. According to the surveys, this program showed a positive contribution to the effects: village harmony, visitors increase, village income. However, It's contribute in short term objectives, but has not yet reach the ultimate goal such as regional development through visitors and village income. We found some problems in the monitering, on the agreement with farmers, range of village activities, operating AgriX program, etc. Finally, we suggest some proposals ; 1) to redefine the aims and range for the program, 2) to clarify a village action program, 3) to strength the admission procedure, 4) to designate district based on landscape resources survey.

This research was carried out in a farm situated in Malkara District of Tekirdag Province (Turkey) in 1994-95, and the effect of genotype and environmental conditions on some characters and variations of these characters in terms of silage yield in 8 dent corn varieties were determined. The results of this research showed that leaf weight, stem diameter, and silage yield had a low broad sense heritability while the number of leaves per plant had a high heritability. Yield performance of varieties varied to a significant degree because of variations in rainfall rate during the growing periods. Leaf number, silage yield, leaf weight, stem diameter, plant height and ear weight varied between 13.33-17.33 number, 8,443-11,114 ton/hec, 152.8-244.2 g, 2,615-2,965 cm, 216.5-252.5 g and 176.2-285.8 g, respectively.

As results of not selecting and using farm well pump properly , it's running regime is far away from high efficient zone and running efficiency of farm well pump is lower. The paper analyses unhealthy tendencies of technical state of diving-electric pump, deep well and centrifugal pump which are commonly used in our country. The paper also summarizes several technical innovation plans to raise efficiency : stage change plan, diameter change plan, speed change plan and synthetic technical innovation . Each plan gives a detailed introduction of designing and construction manners, through practical measuring , the synthetic efficiency of innovated well pumps raise above 30 percent. Economic benefit is evident.

Large amount of water is diverted annually for irrigation along the Yellow River. Owing to the tremendous sediment carried by the river , sediment deposits is an important problem in irrigation and drainage system. The sediment has to be taken out by machines from the irrigation system, otherwise water can not be available in the right place at the right time. In order to improve the sediment desilting efficiency, the sediments that settle in certain sites of a irrigation system must be removed by different desilting machines with special performance and working conditions. Those certain sites include : the diversion canal in the flood plain , the mouth of inlet, settling basin , irrigation and drainage system. In view of removal sediment above, the paper presents the ideas of type selection of desilting machines applied to certain sites. Proposals of making further improvement on performance for some desilting machines are also put forward.

The hydrologic model FESHM was introduced and its applicability was investigated in an attempt to analyze the rainfall-runoff relationships of urban small watersheds and to hereafter predict the envi-ronmental changes. Basic data on rainfall, water level, geomorphological characterisitics and land use were obtained from Yeonwha stream watershed located in Chonju-si Dukjin-dong. WL-5 for simulation o subshed WS# 1(136.7 ha) with urban district and WL-1 for total watershed WS#5 (278.78 ha) we'e selected as gaging points. The main results gained through applications were summarized as follows. 1. Direct runoff ratio caalculated from a simple separation method for WS#5 WS# 1 was 2O~39%, 38~62%, respectively. 2. Simulations for the runoff estimation were carried out for each watershed using 5 rainfall events, the simulation errors had the range of 2~ 30%, O~ 63% and O 120 minutes for the runoff volume, peak flow and peak time, respectively. 3. The effect of landuse change by urbanization was tested to WS# 1, runoff volume before development was estimated as from tenth to twentieth against after development.

The objective of the study is to prepare input data for FIA (Flood Inundation Analysis) & FDA (Flood Damage Assessment) through rainfall-runoff simulation by HEC-HMS model. For HwaOng watershed (235.6 $km^{2}$), HEC-HMS was calibrated using 6 storm events. Geospatial data processors, HEC-GeoHMS is used for HEC-HMS basin input data. The parameters of rainfall loss rate and unit hydrograph are optimized from the observed data. HEC-HMS was applied to simulate rainfall-runoff relation to frequency storm at the HwaOng watershed. The results will be used for mitigating and predicting the flood damage after river routing and inundation propagation analysis through various flood scenarios.

The objective of this study is to make the development computer model of a rural village in EumSung-Gun, ChungChungbuk-do. The study district is ChoChon-Ri, WonNam-Myun, EunSung-Gun, and we investigated literature data and field survey in-site at the viewpoint of rural amenity of village unit. The procedure in this study is multi-variance analysis, extract the amenity of the village, make the developing direction, concept planning, and make a computer model.

This paper attempts to characterize general tendency in water level fluctuations at paddy fields, that may be important to efficient irrigation water uses Banweol district was chosen to be the study area, and water levels among irrigation practice parameters were measured daily throughout the irrigation periods of 1985-1986. Time series analyses showed that water levels at fields have strong serial correlationships. A rather long term periodicity was also observed from spectral analyses. Correlationships between water levels at adjacent fields ranged 0.4-0.9, indicating wide variations in irrigation practices. The water levels showed little correlationships with meteorological factors like evapotranspiration, nor with irrigation practices like water supply rates. Standard errors of the average water levels were computed for different number of field plots within a block. The results indicated that low level areal coverage of gauging plots may be applied for field monitoring of daily water level fluctuations.

The irrigation reservoir operation models developed were tested with weather and field data, and the sensitivity of the water requirement deficiency indices(WRDI) were checked with different initial reservoir storages, irrigated areas, and other water uses from the reservoir storage. Seven reservoir release rules were applied to Yongseol Reservoir. Twenty year WRDIs were computed to check performances of those reservoir release rules. Mean WRDIs were 138, 198, 198, 200, 240, 344, and 1033mm for ROM, TOS, COS, CRR, MSC, FAS, and SRC, respectively. The results indicated that ROM contributes consistently to higher operation efficiencies of an irrigation reservoir. The test results of LFROM and SFROM showed that reservoir operation with the proposed optimization technique ROM would be better suited for an irrigation district than those with the other rules. And the proposed model could be used as a tool to improve reservoir operations.

말라위 농촌지도사업은 최근 농업개발에서의 부족한 기여와 소농의 요구에 부응하지 못한 측면에서 많은 비판을 받고 있다. 그럼에도 불구하고 농촌지도사업은 농촌생활과 농촌빈곤 문제 개선을 위해서 중시되고 있다. 말라위 농촌지도사업은 공공부문과 민간부문에서 많은 도전을 받고 있다. 이러한 도전에 분명하고 적극적인 대응은 모든 농가들에게 편익을 제공하고 정부정책 목적을 달성하기 위한 농촌지도사업의 미래의 모습을 만드는 데 있어서 매우 중요하다. 말라위 농촌지도사업의 당면과제는 민주주의, 시장자유화, 분권화, 에이즈, 공공자원부족, 공공부문개혁, 협력 등이다. 이를 달성하기 위하여 말라위 농촌지도사업은 복합적인 지도사업수요를 제공해야 하고, 식량문제와 빈곤문제해결을 위하여 협력을 촉진해야 한다. 또한 지도사업은 모델빌리지접근법(Model-village approaches)을 기초한 지역농촌지도사업 시스템을 통하여 모든 농가들이 접근할 수 있고 질높은 지도사업 서비스를 추진해야 할 것이다.
