Under the WTO system in the world, our country's apple industry must be set in quite a new aspect. For new apple industry with competition power, we should establish apple industry development strategies as follows. First, to change the present apple trees to the lowered or dwarf tree with high density planting system using M9 rootstocks. Second, to expand the size of apple orchard management and to bring up as professional apple farmers. Third, to develop the integrated apple production system considering environment and human being. Fourth, to innovate improved harvest, storage and shipment system. Finally, Rural Extension Institution should activate the farmer's training and produce the apple nursery trees of better quality.

The objective of this study is to provide direction for agricultural extension services in an age of localization. Agricultural extension services has carried out most of its activities by central direction and control. The central planning and management resulted in disappointment, inflexibility, and lack of responsiveness of the central bureaucracy. Facing localization in recent years, the extension system has not been satisfactorily developed to meet local demands. Korea has to choose to decentralize its extension services. The decentralization of extension services involves the transfer of planning, decision making, and management from the central government to the local level.

This study reviewed a broad range of existing reform options, and on the basis of this review proposed a number of initiatives for institutional reform in developing countries. This strategies were intended to help FAO staff to provide guidance to the developing countries for the reform of their agricultural and rural extension systems. The paper defines the distinction among extension as a function, agricultural extension as part of a larger knowledge triangle, and agricultural and rural extension as an expanded concept of knowledge and information systems. The focus is on new measures that promote food security, market-driven system, and highly competitive agribusiness enterprises. Moreover, this study focus on the tensions that exist between the modern force of globalization and the traditional forces of culture, geography, and community.

In General, the hydraulic system of T-50 Advanced Trainer is applied to flight control system, wheel & Brake system and fuel system for aircraft operation. The hydraulic system is operation with pressure of 3000psi. and many mechanical parts which is operated by hydraulic system has been stressed in incomplete environment same as heat and friction. for example, Oil leakage had occurred in the shutoff valve of FFP used in a certain period of time. After study, The crack progressed by fatigue due to the irregular hydraulic pressure and vibration has been identified as the reason of oil leakage. This paper presents life cycle extension plans of FFP shutoff valve by configuration improvements of shutoff valve and FFP hydraulic motor.

There are many opportunities for Agricultural Technology Centers and for local communities to benefit from the computer and internet and compete in the information age. However, many rural communities appeared to lack human and financial resources required to enable access to the computer and internet. A case of implementation process of establishing agricultural information system at Asan Agricultural Technology Center during the last 10 years were presented. Extension educators took leadership role in facilitating the educational needs of farmers in terms of related resources for the computer and internet extension. To better prepare communities for the information age, community access was critical for promoting the technology and improving proficiency of local community members in its use, extension educators need to take leadership role in assessing community ability to provide internet access points for people without computers. Extension educators at city/county Agricultural Technology Centers may initiate to attract people with internet needs. computer resources, technological experience, and know-how for setting up internet access points in community locations.

The purposes of the study were to; 1) examine the diffusion and adoption of new agricultural technology in rice farming, 2) survey the status of agricultural education institutions on technology transfer, and 3) explore the linkages between agricultural education and extension for more effective reinforcement strategies to further the diffusion and adoption of new agricultural technology in Korea. Literature review, field survey and panel discussions were employed to strengthen the linkages among agricultural education, research and extension in Korea. As the results of analysis of the diffusion and adoption of new agricultural technology in rice farming following recommendations were offered; 1. Extension services have helped Korean farmers in achieving self-sufficiency in rice and year-round supply of green vegetables as well as upbringing rural youth, however, government changed the status of extension educators from central government staff to county/city government staff since 1997. This brought about various problems such as: decreased morale and number of extension educators, thus weakening the extension education function, weakened linkages between national and local extension offices, less opportunity for in-service education of extension educators, and weakened linkages between agricultural research and extension, etc. 2. In order to insure that extension educators are high caliber professional individuals, it is crucial to establish a system that nationally recognizes these individuals as such, and that provides a professional development path. It is important to restore the morale of extension educators to continually achieve the national goals of food production, balanced national development and preservation of environment, at the same time to meet increasing needs of farmers. 3. Because of the critical importance of diffusing innovations to agricultural producers in order to ensure quality and steady food supply, it is crucial that these issues be addressed before the extension service further deteriorates. Further research activities on agricultural extension should be conducted for more effective agricultural extension system in Korea to achieve a greater rural, national and regional development. 4. Research and implementation activities should be emphasized and encouraged to improve the cooperation and collaboration among agricultural education research and extension to better serve farmers' educational and information needs. National level research activities should be encouraged to improve the effectiveness of agricultural technology transfer including internet education programs for farmers in Korea.

This paper presents a new nonmechanical rehabilitation system driven by magnetic force. Typically, finger rehabilitation mechanisms are complex mechanical systems. The proposed method allows wireless operation, a simple configuration, and easy installation on the hand for active actuation by magnetic force. The system consists of a driving coil, driving magnets (M1), and auxiliary magnets (M2 and M3), respectively, at the finger, palm, and the center of coil. The magnets and the driving coil produce three magnetic forces for an active motions of the finger. During active actuations, magnetic attractive forces between M1 and M2 or between M1 and M3 enhance the flexion/extension motions. The proposed system simply improves the extension motion of the finger using a magnetic system. In this system, the maximum force and angular variation of the extension motion were 0.438 N and $49^{\circ}$, respectively. We analyzed the magnetic interaction in the system and verified finger's active actuation.
