In order to investigate the action mechanism of higenamine on cardiac muscle cells, the isometric contraction and transmembrane action potential in rabbit papillary muscle preparations taken out from tight ventricles were observed. The isometric contraction and action potential were recorded in the control Tyrode solution and higenamine-Tyrode solution in which the preparations were kept beating (1 Hz.) for about 30 minutes to get stable data. The resting membrane potential, amplitude of action potential amplitude of overshoot potential, time of repolarization to 60%, 90% of the amplitude of action potential and the first derivatives of potential recorded transmembrane action potential in control Tyrode solution and higenamine (2.5×10^-7gm/ml) Tyrode solution in which showed about 130%-150% of positive inotropic effect compared with those controls. The following results were obtained. 1. Higenamine showed no effects on the time-to-peak tension. 2. Higenamine showed almost no effects on resting membrane potential, amplitude of action potential and overshoot potential. 3. Higenamine significantly shortened to repolarize 60% or 90% of the action potential from 218ms and 264ms in the controls to 200ms and 246ms respectively. (p<0.005) Therefore. the maximum values of the first derivatives of potential variations (- Vmax) in the plateau phase an d repolarization phase were also significantly increased from 16.3V/sec in the control groups to 17.3V/sec in the higenamine-treated groups. The above results which showed positive inotropic effect and simultaneously shortening of action potential duration by higenamine suggest possible involvement of the increase of slow inward current.

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.

There have been various flower exhibitions in many countries such as Netherlands, Japan and China so as to encourage the growth of flower industry since they recognize the value of flower as cultural goods. Chungnam Province government, also endeavoring to make the regional flower industry into high valued agriculture and exporting industry, plans to open the international flower exhibition in Anmyon-Do from April 26th, 2002. This flower show, first held by local government and featuring mega-event tourism, is expected to contribute to initiating flower industry and related business in Chungnam region. However, the flower exhibition may not be said to succeed if it does not play enough to trigger the role in expanding its effect on post growth of regional flower industry. This paper aimed at suggesting strategies of maintaining festival boom of post Anmyon-Do flower fair and contributing to take off of flower agriculture and its related industry as follows; 1) inviting various flower business activities into exhibition places 2) establishing flower village town attracted by tourists 3) devising the flower R&D center 4) organizing helping center for infant flower business group.

Rank of Chungnam's flower industry in Korea is sixth in the number of lower farming household and fifth in the flower cultivating land size in 2000. However, based on the SWOT analysis of Chungnam's agro-environmental factors influencing flower growing, it is noted that further shift of the regional flower industry up to 2nd highest rank nationally can be demonstrated. Strategies for achieving such targets are suggested as follows ; 1) specializing in flower varieties with regional comparative advantage, such as orchids, lily and rose, (2) establishing the educational system for farmers to manage the risks of market price fluctuation, flower cultivation and agricultural finance properly, 3) enlarging the investments in R&D and research facilities 4) assigning the efficient function and communication among the local government, farmers and agricultural marketeers so as to increase th flower exportation.

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.

Changing environments in agricultural business make it necessary to promote the cooperative farming system so as to scale up farming size, which may contribute to increasing competitive power. Therefore, rural and fishery development program was established in 1990 to encourage individual farmers to jointly form the agricultural company or farming cooperatives. However, while the number of agricultural corporations has rapidly increased through the governmental support, their business achievements become worsening mainly resulting from unplanned and careless management practices. This paper suggested following strategies for management process reengineering to improve the efficiency of agricultural corporations; challenging business initiatives to enlarge volume of sales amounts, maintaining the optimal level of participants and physical assets for cost savings, and proper use of information technology and consulting agencies.

It will become necessary for farmers to adopt information technology into commercialized farming system, since its productivity is increasingly linked to how to exploit the agricultural information. The purpose of this study is to examine the current status of information technology and to suggest ways to utilize the information technology for innovative farm management. Internet should become more important instruments which farmers might utilize in order to collect and mine the agricultural information because of its rapidity, reliability and precision. Also farmers should be encouraged to adopt a GIS-based farm management decision support system and to integrate the market information and geographic information such as soil, water, temperature, etc. for optimal decision making. Another way of improving farm management is to make farmers use agricultural accounting software for individual farmers and develop farming simulation system which analyze a farmer's current financial condition and suggest how to improve it. Making home page would be major marketing strategy for farmers to promote the sales of agricultural products.

This study was focused on analyzing the impacts of e-commerce on the farmer's management behavior and suggesting alternatives for the development of e-commerce in agricultural industry. For this study, survey was conducted for 24 farmers who sell agricultural products through e-commerce in Chungnam province. The results of study are as follows; First, farmers have changed their management practices in terms of production, marketing and processing by using the information of consumers' preferences while doing e-commerce business. Second, farmers have attempted to differentiate their product through product brand and customer relationship marketing, because they recognized the importance of developing marketing techniques adapted to e-commerce system for more revenues. Third, if quality certification system of agricultural products is introduced under e-commerce, farmers would use it for their environmentally sounded farming because they expect to increase their income. Fourth, 75% of the farmers sold their product at retail price. It means that e-commerce farmers act as a price maker rather than price taker at e-commerce market, who will be encouraged to have larger business size resulting in more added value. Based on the results of study, we suggest that there should be reduction of service charge for credit card, and encouragement of B2B transaction for the economy of scale and introduction of quality certification system so as to establish e-commerce system of agricultural industry as soon as possible.
