This study has tried to illuminate a shocking phenomenon, the import liberalization of agricultural products in the aspect of Consumer consciousness. It has been applied that Table Analysis by using computer programming for instance-MINITAB, and Correlation Analysis and Multiple Regression Analysis, things like that. The results of this study are as follows; 1. Comparing domestic and imported stuffs, Comsumers came to awareness that domestic products superior to foreign's in the cases of the degree of freshness, taste and pollution damage, in the meanwhile, inferior to the cases of price and wrapping. Food self-supplyment is considered as one of the most important things of all, moreover, by most comsumers and health food and conventional food are favored by high class people. 2. Bying imported stuffs could clearly be fatal blow to our agriculture is fully recognized among consumers, what is more, there would only be doomed to our agriculture, too. 3. The most mass-purchasing imported stuffs by consumers illustrates in order; Beef, Banana, Coffee and Tabacco etc. The most significant elements why consumers buy foreign product is that the prices of them are relatively lower than those of ours. Besides, the next causes lies to non-producing stuffs and curiosity. 4. It must've been generally conceived by most consumers that Open-the-market-policy has been progressed for USA's repression and our monopolistic capital. Therefore, they demand that our market should be contained against unadviciable wave, moreover, keep paying attention to the policy how it will work to protect Korean agriculture. 5. Consumer attitude toward buying imported agricultural products is double-faced, Never-buy occupied only 24.4 % among respondents, but overwhelming respondents say non-producing stuffs can be obtained selectively. In this case, however, never-buy-movement would be backed by consumers in proportion to their educational background. 6. Various consumer minds surrounding Open-the-market-situation, in the end, has been analized econometrics through eleven variables to approach accurate fulfillments.

Rice culture in Korea has a long history ranging over two thousand years. In the agriculture economy of pre-mordern Korea, however, its importantce was not as great as generally assumed. In fact, rice culture reached full development only after the 1920s when the Japanese colonial government carried out its drive to increase rice production in the Korea peninsula. It was not until the mid-1930s that rice became the staple in Korean diet. This can be attributed to two factors : (1) a mountainous topography that provides little irrigated fields and (2) a climate characterized by droughts in spring and heavy precipitation in summer. The present paper attempts to answer some of these questions. Specifically it will focus on these : Did the development of rice culture actually result in population growth? What are the salient features of agricultural develdpment and population grow in traditional Korea? Does the case of Korea conform the prevailing generalization about the agriculture in East Asia? I have discussed the development of rice culture and population growth in the Chosn dynasty, focusing on the relation between the rapid spread of transplanting and the rapid growth of population from the seventeenth to the nineteenth century. Here are my conclusions. (1) The spread of transplanting and other technological innovationsc contributed to the rapid growth of population in this period. However, we should also note that the impact of rice culture on population growth was rather limited, for rice culture was not the mainstay of agricultural economy in pre-modern Korea. Indeed we should consider the influence of dry field cropsn population growth. Nevertheless, it is obvious that the proliferation of rice culture was a factor crucial to population growth and regional concentration. (2) How should we characterize the spread of rice culture in the whole period? Evidently rice culture spread from less then 20% of cultivated fields in the fifteenth century to about 36% of them in the early twentieth century. Although rice as a single crop outweighed other crops, rice culture was more then counter-balanced by dry field crops as a whole, due to Korea's unique climate and geography. Thus what we have here in not a typical case of competition between rice culture and day field culture. Besides, the spread of rice culture in the seventeenth and eighteenth centuries accomplished by technological innovations that overcame severe springtime drought, rather than extensive irrigation. Althougt irrigarion facilities did proliferate to some extent, this was achieved by local landlords and peasants rather than the state. This fact contradicts the classical thesis that the productivity of rice culture increased through the state management of irrigation and that this in turn determined the type of society. (3) We should further study other aspects of the transition from the stable population and production struture in the fifteenth and sixteenth centuries to the rapid population growth and excessive density of population thereafter. We should note that there were continuing efforts to reclaim the land in order to solve the severe shortage of land. Changes also took place in the agricultural production relations. The increase in land producrivity developed tenancy based on rent in kind, and this in turn increased the independence of tenants from their landlords. There were changes in family relations-such as the shift to primogeniture as an effort to prevent progressive division of property among multiplying offspring. The rapid population growth also produced a great mass of propertyless farm laborers. These changes had much to do with the disintegration of traditional social institutions and political structure toward the end of the Chosn dynasty.

The objective of this study is to examine the structure and transition of fertilization system in the 18th century. Especially, on the basis of this analysis, We can find the development of agricultural productivity in Chosun Dynasty. The improvement of fertilization method in the 18 century is found from all items -i,e-the time and object for fertilization, change of the concept in individual fertilizers. The transportation and the double - cropping of rice and barley in a paddy field had accomplished the improvement of fertilization method. Then, the development of agricultural productivity in a guarantee of higher fertilization method contributed directly to realize the consciousness of peasant's landownership.

The main purpose of this study is to examine agricultural technologies through plowing and hoeing. One of the purposes on which this study is to analysis process of development and divergence of plough and hoe. The following facts are significant findings ; 1. In early Yi - dynasty, tilling implements used by ard plough and mould board plough did use in three south province, most region mainly used ard plough. Therefore, farming in early Yi - dynasty is extensive. 2. The mould board plough diffused in many fann house, spring farming and autumnfarming formed complet system in early 17th Century. But works of hoeing was continuing to save labor by long hand hoe. 3. Finally in 17th century, Small - scale independent farming ceaselessly tried to make his basis with transtortation intensive farming method. But Small - scale independent farming had not stafely base because extensive farming method continued in this peorid.

This paper is studied in order to examine eight provinces as Agricultural zone in the early Chosun-Dynasty. The research method of this study depends on discriminant analysis. The research data is obtained from geography of Sejong sillok. In this approach, we believe the possibility of more scientific analysis of agricultural zone. So all cross-sectional data of this period were analysed by means of the discriminant analysis method. In the discriminant analysis of the eight provinces, 54.6% of the country were discriminated. In the territorial map, Kyongsang and Cholla were crossly adjoined and Chungcheong was located in the middle of them. While, Kyonggky and Hwanghae were adjoined in the center, and Pyongan and Hamgil were crossly adjoined, too. And Kangwon was located in the middle of them. Consequently their regional distribution varied widely and the agriculture of this period had considerable regional gaps.

This study attempted to introduce Fei-Ranis's agricultural development theory and discuss its problem for the rural development of less developed world. Fei-Ranis systematized the development process of Western European economy on the ground of dualism. They divided the process into 4 stages by the concept of 'mode of operation'. Paticularly, they consider agrarian mercantilism as take-off stage and its development were achieved by the increase of trade margin and labor productivity. Especially, they thought that only agricultural revolution through the diffusion of internal exchange economy and construction of tree-star system can accomplish favorable transition to industrial capitalism. In order to promote this agricultural development, less developed world must abolish short-run agricultural policy and propel 'learning by the contact' strategy through 'tree-star system' and 'parellel development.' In reality, it was problematic that the contemporary less developed world is trying, in the course of a few decades, to imitate Western European experience with development over the last four centuries. But Fei-Ranis ignored qualitative aspects of agricultural development by tree-star system and also it is criticized that they considered agricultural development process of less developed world follows only that of Western European classical process.

This study attempted to proposed the strategies for development of peach packinghouses. The overview of the conditions of existing peach packinghouses located Chongdo county was provided. Then, the grading system of packinghouse was newly suggested. In empirical analysis, the optimal size, location, and equipments were taken into account for the case of establishing new packinghouse. The main finding of this study was that the planning and construction of peach packinghouse should be executed in accordance with the regional peculiarities. Specifically, First, the packinghouse could make higher profit by high-quality goods using realistic grading/standardization. It would be preferred by customers that the effective itemization of fruits like peach. Second, it would be necessary that the scale of packinghouse was examinated in the county or town level. Third, in order to make an effective management of the packinghouse, several alternatives for operation were suggested. Also the software of packinghouse should be arranged to satisfy the packinghouse, producers, and customers.

Packing house is the regional center in which packing, sorting, storage, and selling of harvested fruits are taken care of all together. It is located at the producing centers, and commercializes their apples. Apple grading policies of chief producing centers should concentrate on enhancing functions and roles of its local packing house. Consequently new packing house policies for enacting individual grading standards at national and local levels should be developed. This study is to develop Korea packing house on the basis of field survey in New York State. Increasing the utilization of packing house is the main key to the success of apple grading project. Therefore, effective arrangement and utilization of sorting facilities should be evaluated and new system which enables apple farms, local cooperatives, and corporations to joint-utilize packing house must to be established.

The actual status of production, management and export of 96 traditional food processing companies which supported by the government in Kyungpook province were investigated. Governmental support contributed to the increase of farmhouse income, employment and depreciation of agricultural products a bit, but it was supported mostly to unexperienced party. Technologies for food processing developed in institute and college were little. 42 percent of packaging design was developed by service commission, but the agency was very limited. Total export price in 1996 was 2.3 billion Won, but it was decreased in 1997. The responce to the prospect of traditional food processing work, 37.5 percent replied that this work can bring up as exportable product, but ambiguious response was a little. To settle a weakness of farming food processing work, the establishment of special marketing comapny was required and this company should accomplish marketing advertizing and exporting business.
