Rural extension work in Korea has been carried out as a national government project by the Rural Development Administration since 1962. But almost all of the extension workers transferred to local government employ in 1997 and the 7,480 extension workers in 1997 decreased to 5,082 by the end of 1999 through restructuring of the government system. Traditionally, the extension worker has carried out educational jobs but many extension workers was to carry out the administrative responsibility in addition to the educational job as the rural extension system was changed. This study was to evaluate the rural extension system under the localization, extension activities, methods, extension worker's morale, and so forth. Most of extension workers are embarrassed about the changing of the extension system and their duty.

After late 1980s, new approach is needed for satisfying with people's various information needs and better quality of life on Korean extension service. The United States began modern extension service at first and has influenced many countries. Cooperative extension service has helped people practically by searching into people's problem and developing various channel to diffuse. Cooperative extension adopts changes in extension service environment and puts them to use. Based on the extension service in the United States, following recommendations were suggested; 1) carrying out extension service to meet the changing needs of people, 2) strengthening the extension function of agricultural Colleges, 3) review of cooperative agricultural research and extension, 4) developing programs and management, 5) accumulation agricultural information and utilizing them.

Fatigue analysis for life extension of a ship is different from that of a newly constructed ship since the current corrosion margin and voyage routes of the past and future must be considered, thereby complicating the life extension procedure. This research introduces the fatigue analysis case for the life extension project of a moss LNG carrier using full spectral fatigue analysis, which has been previously used for newly constructed ships. It is expected that the fatigue analysis methodologies and full spectral fatigue analysis program used in this study will be applicable to other life extension projects.

The objectives of this study were 1) to evaluate the first year of localization of agricultural extension in Korea, 2) to present the development directions and implications of agricultural extension service in the next year of localization. The major results and implications were as follows. 1. The positive changes in localization were to establish local special projects and to work in agricultural extension without personnel changes. 2. The negative changes in localization were increase of unnecessary work load and decrease of morale because of lowered status. 3. The development directions were to cut back unnecessary work load, to rearrange an office, and to return to the national status of extension personnels.

Agricultural extension services in Korea began in 1956, and led self sufficiency of rice through the 'Green Revolution' in 1970's, and a year around supply of green vegetables through the 'White/Vinyl Revolution' in 1980s. The developmental stages of agricultural extension services in Korea, in terms of major purposes, observed by the researcher were as follows; 1) Stage of production guidance when increase in production was directly related to increased income of farmers, 2) Stage of management guidance, when agricultural extension were not only concerned in increasing production, but also in management and marketing, and 3) Stage of improved welfare, when extension services put more emphasis on welfare of farmers in terms of quality of life, as well as increased production, management and marketing. Since late 1980s, farmers in Korea realized the fact that increased production may not lead to increased income. because of this, farmers also wanted improvement of management and marketing. Extension changed the identified needs of farmers to new knowledge, information, and technology in their farm business operation including management and marketing. Loosened cooperations among the central, provincial and local levels after localization of extension services since January 1997 should be strengthened. Provincial level monitoring and supervising should be enhanced for more effective agricultural extension services to meet the changing needs of farmers in the future.

Agricultural extension has contributed enormously to agriculture and farmers, since Rural Development Administration(RDA) was founded in Korea. However, as the decentralization got started and world environment has changed, agriculture extension shrank by transferring the function of agricultural extension to local government. According to public opinion appeared on the bulletin boards of RDA web site, many people suggest that agricultural extension should be improved from the current system and services. Findings in the transfer of the extension system from national status to local government showed some advantages and disadvantages; 1) Agricultural extension services was decreased sharply by a large dropping in the number of extension educators. 2) The identity of agricultural extension services was disappearing. 3) The extension projects when matched with local features could be better implemented. 4) The lives of extension educators were better stabilized. Rural Development Administration intends to transfer the director of the local Agriculture Technology Center to the national status. This would return all current extension educators step by step to national positions. By doing so, agricultural extension scholars and farmers are welcoming this agenda. On the other hand, the extension educators themselves were divided by contradictory opinions Therefore, government should search for the better alternatives to establish more effective system with considerations of various aspects in activating the agricultural extension services.

It is nearing the establishment of KAC(Korean Agricultural Chamber) as an institution for intensive reflection of farmer's public opinions in agricultural administration. In this study, researchers examined the management of Agricultural Chambers in France and Japan, which have experienced the action of Agricultural Chamber in advance of Korea. And discussed the anticipated change in agricultural extension taking advantage of departure of KAC. Discourses and movements to establish KAC is putting pressure the existing agricultural extension system into innovation. Taking a side view that there were little contribution of agents belonging to the existing agricultural extension agencies, the problem of restructuring agricultural extension system has assumed very serious dimensions. Therefore, agents in agricultural extension agencies should lay their own view before the probable reorganization of agricultural extension system.

This paper evaluated the economic feasibility of the life extension of Kori unit 1 and Wolsong unit 1 according to the types of the nuclear power plants (NPPs) and the life extension period comparing to the levelized costs of energy (LCOE) of the new NPPs, coal-fired plants (CFPs), and combined cycle gas turbine (CCGTs) which proposed in the $7^{th}$ Basic Plan for Electricity Supply and Demand. The economic feasibility of the life extension of NPPs using LCOE method is affected by the types of NPPs, lifetime extension periods, discount rate, and capacity factor. According to the analysis results, the pressurized light water reactor (PWR) is more economical than the pressurized heavy water reactor (PHWR). Comparing the economical efficiency between the life extension of NPPs and other alternatives, the operation of the PWR for 20 years is more economical than the one of new NPPs and CFPs. However, 20 years of life extension of PHWR is more economical than the CCGTs, but less economical than new NPPs and CFPs. In summary, the 20 years of life extension of the NPPs seems to be more, especially for the PWR, which is more cost effective than other generation alternatives. Therefore, the government policy of the life extension of NPPs need to be a selective approach that simultaneously considers both safety and economics rather than closing all NPPs.
