For rational agricultural land use planning, it is quite necessary to get hold of land suitability precisely and to make decision on land use patterns accordingly. In the methodological viewpoint, objective and scientific evaluation techniques for land suitability classification should be supported for the systematic land use planning. As one of technical development approaches to rational land use planning, this study tried to frame a land suitability evaluation system for agricultural purposes. Evaluation unit is defined as a tract of land bounded by road, other land units and topographical features. And quantification theory was applied in the determination works of evaluation criteria. The administrative area of Namsa-myon(district), Yongin-si(city), Kyunggi-do(province) was selected for the case study. In order to check the feasibility of the evaluation system developed in the study, field check team, consisting of 2 government officers and 2 representative farmers, carried out evaluation works by observation on 148 sample land units, 10% of total 1,480 ones. Between estimated and observed results, there showed very good relationship of its multiple correlation coefficient, R=0.9467.

The city's countryside is adjusting to change by urbanization. The recent changes in rural landuse and damages of local landscape characteristics are very serious. But, few studies address the relationship between land-use and quality of landscape for these area. The aim of this study is to clarify causes and problems of the change through investigating changes of landscape as a function of land-use. The results are as follows 1) The change of landscape can be seen as a functional of land-use. Landscapes are characterized by changes of regional environments. These are the urban-rural fringe area which need special consideration for urban development and also for rural landscape quality. 2) 11 types of landscape patterns are found for landscape management. these are Regional commercial area, Apartment development, Recreation & seisure, Golfs, Housing complex, Industrial complex, Vinyl house, Rural village, Evaded facilities, Rivers, Cultural heritages. These landscape types are explained as 'stimuli-responses model'in Bryant's Forces of urbanization. 3) The policy implications of these study are as follows : First is the necessity of landscape management in Grown Management Zone and Natural Reserved Zone in the Metropolitan level, Second is the necessity of development control in semi- agricultural area. The last is the necessary of long range management plan in the urban-rural fringe area.

한국 재래종 대두(Glycine max) 943계통과 강원도 지성 수집종 야생종(G.soja) 50계통을 polyacrylamide gel electrophoresis와 isoelectric focusing 전기영동으로 LAP 동립효소를 분석한 결과를 요약하면 다음과 같다. PAGE에 의한 Lap1*b는 재래종과 야생종에서 가장 흔한 대립인자였다. Lap1*b의 대립인자 빈도는 한국 야생종(0.94)에서보다 재래종(1.00)에서 더 높았다. 이러한 결과는 한국 재래종 대두는 Lap1 유부자좌에서 Lap1*b 대립인자로 고정되어 있음을 나타내는 것이다. IEF 전기영동법을 이용하여 pH 4∼6.5의 gel에서 LAP 동립효소의 band type을 확인한 결과 재래종과 야생종에서 I type과 II type의 band type을 확인하였다. 재래종과 야생종에서 II type이 6계통(7.2％)과 4계통(8.0％)으로 각각 나타났고 I type은 79계통(92.8％)과 46계통(92.0％)으로 각각 나타났다. 이러한 결과는 다양한 band type이 나타날 수 있는 가능성을 제시하고 있다.

신 간탁지에서 플라스틱 암거배수가 제염 및 벼 생육에 미치는 영향을 검토하고자 1979년 3월에 5m와 8m 간격으로 암거를 설치하고 1983년까지 5년간 호남작물시험장 계화도출장소 시험포장에서 일본형 품종인 진주벼를 공시하여 제염효과와 벼 생육 및 수량 변화를 검토한 결과를 요약하면 다음과 같다. 1. 제염효과는 5m 간격 암거가 8m 간격보다 컸으며, 벼 재배 한계 염분농도인 0.3％에 달하는 년차는 5m 간격 암거 1년, 8m 간격 2년인데 반해 무암거에서는 3년이었다. 2. 암거시공 위치별로는 암거 직상에서 제염효과가 가장 컸고 암거위치에서 멀어질수록 제염효과가 경감되어 암거시공 중간부위에서 제염효과가 가장 낮았다. 3. 암거에 의한 수직적인 배수효과는 30cm까지는 토심이 깊을수록 컸으나 그 이하에서는 점감되었다. 4. 무암거보다 암거간격이 좁을수록 뿌리의 수가 많고 길었으며 뿌리의 활력이 높았다. 5. 무암거에 대하여 무암간격이 좁을수록 수수가 많고, 1,000입중이 무거웠으며 수량도 많았다. 6. 시공 2년차까지는 5m 간격이 8m 간격 암거보다 증수되었으나 3년차 이후에는 암거 간격간에 별 차이가 없었다.

In rural planning, the cost estimation of project is a key factor for planning. Therefore, development of reliable cost estimation method is essential. Recently, new techniques are suggested for determination of project cost using historical cost data. In this study, a multiple-regression analysis was used to determine the cost of the farm land consolidation. The results demonstrated that multiple regression analysis using historical cost data can be applicable to project cost estimation.

In this paper, the basic planning for the creation of consolidated agricultural institutions of Choongcheongnam -Do and its management schemes were established. These institutions, including rural development office, farmers'training institution, original seeding field of farm crops, agriculturial information center, packing design center, agricultural machinery repair center, agricultural scientific conference hall, agricultural museum, agricultural park, farmers'hall and event plaza, are planned to be created. The required area for the site is 1,246,781 m2. 281-22 Jongkyung-Ri, Sinam-Myun, Yesan-Gun, Choongcheongnam-Do and its surroundings is a proper site for the creation of'consolidated agricultural institution because the actual conditions of the soil, traffic network, irrigation and drainage, tourist routes and human resources are very good. The layout of the facilities that would comprise an agricultural institution was organized in consideration of the functions and roles of each facility and the relationships among facilities in this consolidated agricultural institution. It is desirable that the headquaters of consolidated agricultural institution oversees the management department, the planning . administration . information department, the rural development office, the farmers'training institution, the original seeding field of farm crops and the agricultural park.

Land suitability classification(LSC) is an appraisal and grouping(or the process of appraisal anti grouping) of specific tracts(of land) in terms of their relative land suitability for a definEd use, and is one of the land use planning techniques. This paper reviews the selected studies on LSC whose purposes are to especially contribute land use planning in case of Japan, So, this study examines the LSC's application to Korea based on Japanes LSC studies with a view to development of the methods on LSC for rational land use planning in our rural area. The result resolves itself into Table 2. However, it is undesirable to borrow from Japanes LSC studies like that, because of the difference of administrative,geographical,traditional,social and economical conditions. Therefore, it is necessary that the many case studies and examinations should be carried out in order to develop the methods on LSC suitable to Korean actual circumstances.

Observational date is integral in our understanding of present climate, its natural variability and any change due to anthropogenic effects. This study incorporates a brief overview of sampling requirements using data from the first ISLSCP Field Experiment (FIFE) in 1987 which was a multidisciplinary field experiment over a 15 km grid in Konza Prairie, USA. Sampling strategies were designed for precipitation and soil moisture measurements and also detecting land cover type. It was concludes that up to 8 raingages would be needed for valuable precipitation measurements covering the whole FIFE catchment, but only one soil moisture station. Results show that as new gages or station are added to the catchment then the sampling error is reduced, but the improvement in error performance is less as the number of gages or stations increases. Sampling from remotely sensed instruments shows different results. It can be seen that the sampling error at larger resolution sizes are small due to competing error contribution from both commission and omission error.

As a rational decision-making process of county-level area development, this study designed 3-step framework : function-giving(areal analysis) on unit planning area by decision matrix of land suitability, check of typical characteristics of each function area and formulation of its future development strategies. Two alternatives were suggested as the areal analysis method, of which one is equal ordering / valuing technique of checking indices for land suitability classfication and the other preferential weighting technique. And then, under the algorithm specially defined in this study, land suitability maps(Fig.2,3) of the case study area (Seungju-county area, Chonnam-province, Korea) were drawn from the areal analysis results. By use of land suitability classification results, unique characteristics of typical function areas were defined (on 7 types of alternative 1 , 8 types of II ) and their future development strategies were formulated in the case study area, According to the categorization criteria in this study, all the villages of the case area were classfied as a suitable type of function areas illustrated in this study.

This study was carried out to identify the problems and policy alternatives for the improvement of living conditions and environmentally friendly agriculture. The results of surveys on the current situations of living conditions in the rural areas revealed that the main cause of depopulation in Korean rural villages was the lack of social infrastructure and income sources. The current government policies for agriculture geared mainly for improvement of international comparative competitiveness will result in the further disadvantage against the mountainous regions with marginal agricultural lands. Therefore, it is recommended that the agricultural policy should be complemented by the environmental and social policies in the less favoured areas. This can be justified by the fact that the demand for environmental public goods such as recreational opportunities in rural settings uncontaminated by the industrial wastes is growing.

For formulation of the rational land us2 plan in regional base, it is a basic and prior condition to categorize total planning area into some functional subregions by purposely-selected indicators. As one of quantitive approaches to the areal categorization in rural area, Principal Component Analysis(PCA) was introduced and testified its applicability through a case study on Sunheungdistrict(called as myun in Korea) area, Youngpoong-county, Kyungbuk-province, Korea. Areal analysis by PCA was carried out on rurality and urbanity of parish-level area(ri in Korea) respectively. By use of PCA analysis results, classifying matrix was made through categorization of both index scores. Among 18 ri's of the case study area, 12 was classified as rural-dominated areas, 2 as urban- dominated areas, and reamaining 3 as intermediate areas.

As a initial methodological approach to rational land use planning in the county-level area, three types of land suitability classification techniques were examined from the viewpoint of their practical applicability through the case study of Seungju-gun area, Chonnam-province, Korea : major factors' criteria(method I ), principal component analysis( I ), and local monitoring( R( ). Each method has its strong and weak points as shown in Tab.-5. Therefore, when its practical application, there seem to be wide-range methodological selectivities from exclusive use of the best one to intermethodological combination of related ones In the beginning stage, intermethodological combination of all three types were tried to formulate the best solution possible. However, because of reliability problem of method R accrued from non- uniformity of evaluators'quality, only two methods( 1 , E ) were combined into a new evaluation method The applied results of the new combined method to case study area are shown in Fig.-2, 3 and 4.

신개간지에서 삼요소비료시용시 몇가지 물리화학적인 개량방법을 병행하여 실시함으로써 율무재배에 대한 기초자료를 얻고자 신개간지에서 율무를 1985년부터 4년간 재배하면서 율무에 대한 삼요소의 수량반응과 토양특성 변화를 조사·분석한 결과는 다음과 같다. 1. 율무의 초장은 종합개량처리구에서 가장 컸는데 2년차까지는 컸으나 3년차부터는 작아졌다. 2. 율무수량은 종합개량처리가 평균 2.16 t/ha로 가장 많고 삼요소 시용 대조구에 비하여 49% 증수되었으며 다른 처리구의 수량은 심경구>인산구>석회구>퇴비구>대조구 순으로 많았다. 3. 토양의 용적밀도나 경도는 표토에서 3년차까지 계속 낮아지다가 개량제 시용이 없었던 4년차에는 높아졌다. 토양산도는 토심이나 년차간에 큰 차이가 없었다.

The land and sea breeze over the Pusan coastal area is studied by three dimensional mesoscale numerical model. According to the results of the simulation experiments, both Pusan areas and Kimhae areas, the sea breeze began at 0800LST and the strongest at 1500LST and then at 1800LST. After midnight, the sea breeze changed about the land breeze and become weaker than that of the sea breeze in the daytime. Comparisons between calculations and observations showed that the characteristics of diurnal variation and v-component of the wind velocity relatively is similar to the Pusan areas. On the Kimhae areas, however, observations showed time lag which compared to the results of simulation experiments in the velocity of sea breeze and diurnal variation. From the above results, comparisons between calculations and observations is much more similar to the coastal areas than on the inland area.

Land-sea breeze over Pusan district is investigated by performing the numerical simulations with orography on a two-dimensional mesoscale model. The model results show that the sea breeze strengthens and begins to move inland at 1000LST. The strongest sea breeze is occurred at 1500LST and begins to weak at 1700 LST. After 2400LST a weaker land breeze compared with the sea breeze develops. The observed datas and the simulated land-sea breeze is not coinsidented exactly at the event day(1983. 9. 19.). But simulated land-sea breeze is corresponded of synoptic characteristics that was studied previously.

Lipoxygenase는 대두종실에 많이 포함되어 있어 대두의 불포화지방질을 산화시켜 대두 특유의 불쾌한 콩비린내를 나게 함으로서 콩나물을 위시한 많은 대두식품제조공정에서 어려움을 주고 있다. Lipoxygenase에는 L 1, L 2, L 3의 3가지 isozyme가 있는데 그동안 미국과 일본의 학자들에 의해 lipoxygenase 결핍(1 1, 1 2, 1 3)돌연변이 계통이 발견되었고 또 단순 열성 유전 양식임이 밝혀짐으로서 lipoxygenase 문제가 육종차원에서 해결될 수 있는 전망이 보인다. 본 연구는 우리나라 재래종 집단에서 lipoxygenase isozyme 소재를 제공하려는데 그 목적이 있다. 본 실험에서 L 1 결핍계통 KAS 610-3, KAS 621-8이 선발되었으며 lipoxygenase 결핍계통은 일반적으로 소립이고, 지방합량은 낮았으며, 또 본 실험에서 선발된 L 1 결핍 2계통은 특징적으로 콩나방 피해가 컸다. 공시계통수는 적었지만 야생종 대두에서는 lipoxygenase 결핍유전자형이 발견되지 않았다. 우리나라에서 발견된 L 1 및 L 3가 결핍된 4계통이 모두 경남지역의 재래종에 한정된 것으로 미루어 변이투기 역사는 짧을 것으로 추정된다.

비곡종법은 중국의 범승지서 부터 이미 확립 된 체계가 있어서 우리나라도 대부분 이를 인용하여 따르는 경향이 있었으며, 취종법은 비정상형의 종자를 선별해 버리고 우량종자를 선택하는 방식이었고, 선종법도 중국은 수선법을 따랐으나 우리나라는 풍선→절별→수선법을 창안발전시켰고, 최근에는 염수선이 첨가되었을 뿐, 모두가 완벽한 기술이었다. 종자흡습도 측정법이나 종자의 설즙 및 요분, 골즙처리법 등은 그 근간이 고대중국에서 유래된 것으로 우리나라의 농서들도 대체로 이를 인용하거나 다소의 가감을 통하여 수용하고 있었으나 이들 기술이 갖는 타당성은 합리성에 비하여 번거롭고 비현실적이며, 이는 우리나라 입지보다 중국의 한지, Alkali토양에서 오히려 수긍도가 높은 기술로 해석된다. 경지는 농사의 시작을 알리는 작업으로서 천지간에 기통하는 때를 기다려 시행한다는 고래 중국의 농업관을 거의 가감없이 선초부터 선말의 농서에까지 인용하고 있었다. 초경, 추경(혹은 춘경), 기경은 깊게하고 재경, 춘경(흑은 하경), 중경은 얕게 하며, 전자는 저수와 정지를 목적으로 하고 후자는 중경제초를 목적으로 하도록 기술분화 하고 있었다. 그러나 한전의 세역법에서 와 달리 상경하는 우리나라에서는 추경이 권장되고 있었으나 실제로 추경하지는 못하고 있었으며 이런 상황으로부터 시대를 경과하며 우리나라의 기경법은 녹비작물이용법, 엄경법, 분양법, 때에 따라서 건경법 등과 연계시켜 수행토록 종합처리법으로 발전을 이룩하였다. 뿐만 아니라 15세기까지는 새로운 산전과 연안지로의 경지확장을 위한 개간법을 지원하기 위한 농기구로서 윤목사용법이 창안되었고 17-18세기부터는 내외환으로 황무지화한 농경지를 대상으로 우선적으로 노동생산성을 제고시킴으로써 생산력까지 회복시키고자 하였으며, 이를 위하여 중국고대농법인 반종법과 소누법을 재인용 소개하여 왔으나 큰 성과는 불분명하며 드디어 선말에는 이에 대한 현실성을 평가하기에 이르렀다.
