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.

The purpose of this study was to classify the type of customer which is essential to agricultural extension service, specify their needs and identify the performance level of public agricultural extension organization by the needs of customer. To meet these purpose, we conducted a focus group interview and surveyed the agricultural extension workforce. The results of this study are as follows. First, we classify the customer of agricultural extension service as 9 types. Second, the needs by customer types are specified 12 types. Third, those who attached to Rural agricultural development administration and agricultural research and extension service organization in provinces recognize them selves as more performing organization than agricultural technology center in region, except one area.

As a result of the execution of the import liberalization and local autonomy with WTO system launching, centralized rural extension service converted to localized rural extension service. This advent of globalization and localization era affects our over all agricultural condition, moreover the duty and role of rural extension organization which take complete of rural extension, is compelled to diversified and specified technology. In this study, first we will investigate the change of agricultural, rural community, and local rural extension service in globalization and localization era. Second we will analyze the confronted problems of local rural extension service. With this study's outcome for basis, we will present new role and direction of local rural extension service which can contribute to local agricultural development.

Decrease in availability of suitable subbase and base course materials for highway construction leads to a search for economic method of converting locally available troublesome soil to suitable one for highway construction. Present study insights on evaluation of benefits of stabilization of subgrade soils in term of extension in service life (TBR) and layer thickness reduction (LTR). Laboratory investigation consisting of Atterberg limit, Compaction, California Bearing Ratio, unconfined compressive strength and triaxial shear strength tests were carried out on two types of soil for varying percentages of stabilizers. Vertical compressive strains at the top of unstabilized and stabilized subgrade soils were found out by elastoplastic finite element analysis using commercial software ANSYS. The values of vertical compressive strains at the top of unstabilized and stabilized subgrade, were further used to estimate layer thickness reduction or extension in service life of the pavement due to stabilization. Finite element modeling of the flexible pavement layered structure provides modern technology and sophisticated characterization of materials that can be accommodated in the analysis and enhances the reliability for the prediction of pavement response for improved design methodology. If the pavement section is kept same for unstabilized and stabilized subgrade soils, pavement resting on lime, fly ash and fiber stabilized subgrade soil B will have service life 2.84, 1.84 and 1.67 times than that of unstabilized pavement respectively. The flexible pavement resting on stabilized subgrade is beneficial in reducing the construction material. Actual savings would depend on the option exercised by the designer for reducing the thickness of an individual layer.

Agricultural extension services in Korea are faced with increasing demands for more efficient production and managerial technology according to globalization and free trade system. At the same time, three steps of organizational restructuring in 1998 and 1999 resulted in decreased number of organization and manpower, thus, resulting confusion in implementing extension services. To cope with the international and national challenges, Korean agricultural extension services should try paradigm shift including the followings; 1. To establish identity of agricultural extension services in Korea through making laws and regulations in terms of concept, roles, principles. implementation and methods. 2. To implement vitalizations plan through enhancement of national extension service such as food production. raising local specialty products for domestic consumption and producing strategic agricultural products for export. expanding capability of rural women, increasing opportunity for management consultation, supporting digital technology information, and promoting morale and capability of extension educators. 3. To reform agricultural extension system through adjusting the functions of extension service of the Rural Development Administration, regionalizing city and county extension center to provincial level, and changing the status of directors of extension centers from city /county to national government.
