Economic conditions of Korean agriculture have been aggravated since farmers experienced the shortage of labor, instability of farm product price. lack of capital and pressure of opening domestic market. Nevertheless. agriculture must be maintained because structure of national economy can not be progressed without balanced growth of food industry. So the problem that we must solve is to keep agriculture competitive. In that case technology is important in terms of improving productivity, overcoming labor shortage and stabilizing price. This paper is to study the technology adoption on the farm level, focusing on the theories of technology adoption, their empirical test and effect of technology adoption on the farm household income. In this study five theories - independent model, linear model, middle class conservation model. modified middle class conservation model, basic needs and wealfare model- were introduced concerning differentiated technology adoption rate by farmers' class. Based on the survey of controlled strawberry farming in Nonsan County, Chungnam Province. who adopted six kinds of technology, modified middle class conservation model was found to explain five kinds of technology adoption pattern and linear model was useful to explain one kind of technology. that is. irrigation method. These results may mean that controlled strawbary cultivators of middle class were reluctant to accept new technology. There are many variables to effect on the technology accepting rate, that is, farmer's age. labor capacity, education level, cultivation career. size of total cultivated land. and size of strawberry farming land. LOGIT model was used to find which variable influence the technology adoption rate. Results of estimation showed that variables of cultivation career and total land size. of which coefficients were statistically significant at the 5 percent level, might be main influential factors in accepting more than three farming techniques. There was a significant income difference between farm households accepting new methods and those rejecting them. Especially in case of low class of farming group, income of farmers who was adopting new technology was examined to be much higher than that of farmers who did not. adopt. This result suggests that new technology play an important role in increasing farm household income. Finally this study emphasized that there is a need to develop proper measure of technology transfer considering various socioeconomic conditions of farm households.

This paper aims to study regional difference in strawberry farming technology and its causal factors based on the survey of controlled strawberry farmers in three major strawberry cultivating regions, which are Nonsan county of Chungnam Province, Damyang County of Junnam Province and Guchang County of Kyungnam Province. There are differences in variety adoption, packaging and grading method which cause the farming income gap among these regions. Farmers of Guchang County, who adopt new variety Yeobong and packing system, raised highest gross receipts but ranked next to Damyang in terms of net income because of high packing cost. Farmers of Nonsan County earned lowest income because of poor quality and low price in spite of adopting packing cost saving method. Therefore, results of this study shows that successful farming technology depend on whether or not farmers adopt market oriented technology. It is suggested that direction of strawberry farming technology should focus on adopting new varieties which can contiribute to increasing farmers' paid price and developing technology of reducing cost such as labor saving and packing machine.

The geographical position of Joongsan-dong, Ulsan located in enterace to Gyeongju in ancient. It has been connected with Jookdong-ri, Goojeong-dong, Choyang-dong toward center of Gyeongju. These areas had been formed in not only close relationship on common cultural foundation but geographical contiguity. It's difference for character each period that have been indicated changing pattern of graves and burial remains to the Joongsan-dong politic group. We've got to know social structure arranging ranked to make an observation on burial remains even though it's poorer than Jookdong-ri, Choyang-dong politic group in step for wooden chamber tomb. The arranging rank had been subdivided to close the main strength. It had been become on an equal footing between Joongsan-dong and it's around region in step for wooden chamber tomb. It was difference to burial remains that those are various kinds of arms and horse trappings, tools, earthenwares etc. each square of grave hollow had been buried in the tomb. The remains were mostly represented ornament, religious meaning strongly. Joongsan-dong politic group had been become the main strength from wooden chamber tomb step that square form were too lengthy. Each politic groups had started to organize itself for specialization. It had been promoted social specialization from increasing iron arms, tools standed as a symbol for armed strength, production capacity in surrounded stone-type wooden chamber tomb step. All pattern of graves that those are surrounded stone-type, pure, filed stone-type of wooden chamber tomb and stone chamber tomb have been coexisted in Joongsan-dong politic group. The pattern of graves had been selected variously for character of governing classes. It's difference volume of that those are flat form of grave, square of grave hollow, burial remains for each politic status. The Joongsan-dong politic group had been changed volume and flat form of grave, burial remains etc. as 5th century that the group had been started to govern from the Gyeongju directly. 울산 중산동은 경주 구어리와 죽동리, 구정동, 조양동을 거쳐 신라 중심부로 들어가는 관문에 위치한다. 이들 지역은 입지적인 특성과 공통된 문화 기반 위에서 서로 유기적인 관계를 형성하고 있다. 중산동 지배집단은 묘제의 변화양상과 부장유물을 통하여 볼 때, 시기별로 성격을 조금씩 달리한다. 목관묘 축조기에는 주변의 죽동리나 조양동에 비하여 약세를 보이지만 부장유물을 통하여 서열화된 사회구조를 확인할 수 있다. 서열화는 중심세력에 가까울수록 세분되어 있다. 순수목곽묘 축조기에는 중산동과 주변지역 사이에서 대등한 관계를 확인할 수 있다. 다양한 종류의 무기와 마구, 농공구, 토기 등이 부장되며, 묘광의 면적에 따라 차이를 보인다. 유물은 대부분 장식과 의기성이 강하게 반영되었다. 중산동 지배집단은 세장방형 순수목곽묘를 축조하면서부터 중심세력으로 부상한다. 각 지역집단은 자체적으로 지배조직을 갖추며, 성층화가 이루어지기 시작한다. 위석목곽묘 축조기에는 철제무기 및 농공구를 바탕으로 한 군사력과 생산력의 증대로 사회분화가 가속화된다. 위석목곽묘와 순수목곽묘, 적석목곽묘, 석곽묘 등이 모두 공존하며, 지배집단의 성격에 따라 다양하게 채용된다. 평면형태, 묘곽의 면적, 부장유물의 종류가 지위별로 차이를 보인다. 중산동 지배집단은 신라의 직접적인 영향을 받는 5세기 무렵부터 분묘의 규모와 평면형태, 부장유물 등에 제약을 받았던 것으로 판단된다.

Neurofibroma in gastrointestinal tract are presented as localized forms or in associated with neurofibromatosis. Previous reported cases were presented as relatively large sized esophageal mass and treated by surgical resection. However, a neurofibroma was found incidentally during endoscopy in this case. It was presented as palisade like solitary nodules with or without connecting mucosal bridges in lower esophagus. It was treated by mucosectomy and followed up without recurrence. (Korean J Gastrointest Endosc 2002;25:449-452) 식도의 양성종양 중 신경섬유종(neurofibroma)은 아주 드문 질환으로 국내에는 보고된 바가 없다. 신경섬유종증의 일부분으로 신체의 다른 부위와 동반하여 발생할 수 있지만 대부분 국소형으로 발생되는 경우가 많다. 식도의 신경섬유종은 신경인성 종양으로 말초 신경조직에서 기원하며 악성화의 빈도는 극히 낮다. 식도 종물의 크기 증가와 위치에 따라 발현되는 증상과 드물지만 악성화의 가능성 때문에 제거되어야 한다. 증상 없이 우연히 발견된 식도의 신경섬유종에 대해 내시경적 점막 절제술을 시행한 1예를 치험하였기에 보고하는 바이다.

This paper reviews the development of Uruguay Round of GATT talks and forecasts its effect on regional agriculture particularly concerning Chungnam provincial agriculture. Since agriculture is composed of main industry for Chungnam economy, as imports of cheap agricultural products increase, domestic price of farm products will rapidly decrease so that it might discourage domestic production and have severe adverse consequences in regional farm economy. To cope with agricultural trade liberalization, directions which regional agriculture should pursue are suggested as follows; 1) to establish the integrated rural development strategy so as to improve living conditions in rural area equivalent to urban area. 2) to adjust the agricultural institute system facing diversification of farming type, 3) to encourage commercialized farmers in order to maintain adequate faun income. 4) to increase R&D investment on comparatively advanced technology compared with other regions, 5) to foster farmers' organization and to rear young farmers to protect family farms.

This study is to provide a comprehensive overview of the changing vegetable sector of Chinese agriculture and to analyse the competitiveness of Chinese vegetable production. China now produces more than 60% of the world's vegetable supply and that 150 million people are engaged in vegetable production, processing and marketing since the reform of vegetable industry structure started in the late 1980s. As a labour abundant industry, China also features more comparative advantages in the vegetable trade. Although China's vegetable exports still accounts for only 1% of total production, the 5 million tons of export in 2003 makes China one of the largest vegetable players in the international markets. When estimating competitiveness of China's vegetable industry, China's producers' prices for vegetables are founded to be only from 10%~40% of what they are in Korea, while most of China's vegetables have also strong competitiveness in quality. As China joined the WTO in 2001 and expects to increase market share in vegetable trade, the development strategy for Korea's vegetable industry are suggested as follows: 1) focusing on the technology for the growth of vegetable productivity, 2) developing the higher value added vegetable industry through processing, 3) expanding the exported area and leading vegetable varieties.
