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.

Localization trends in Korea and trade liberalization in the world are the important challenges to agricultural extension services in Korea, and strategic directions in terms of system, organization, programs and conciousness would be necessary for adapting to the new circunstances. Some of the measures to improve and activate agricultural extension services in Korea should include the following: 1) Modification of extension personnel appointment regulations to secure specialized extension agents by the provincial administrators and county directors at the provincial and county level rural extension services. 2) Flexible organization and operation of county level rural guidance offices to meet the specific needs of local areas. 3) Strenghening the central government's financial support for effective local extension services in terms of facility and manpower. 4) Expansion of agricultural extension programs for women and urban people and quality inservice training for extension personnel.

In this paper we present the specification development for the localization of interlockings which control routes within a HSR station yard. For the electronic interlockings in Korea introduced from France in the 1990s, it has a complicated hardware configuration and communication protocols in order to secure safety. Now 30 years later, in case of the application of the up-to-date IT technology, it is expected to achieve equal or greater safety and save maintenance costs. Additionally, we develop the specification so as to utilize the stable domestic electronic interlocking technology for general railways, beyond the simple maintenance for the performance maintenance of foreign devices, to high-speed railways. Therefore, we perform a study for the localization of the HSR electronic interlockings by comparing and analyzing interlocking logic units between conventional HSR and general railways.

To be high efficient for a navigation of unmanned ground vehicle, it must be able to distinguish between safe and hazardous regions in its immediate environment. We present an advanced method using laser range finder for building global 2D digital maps that include environment information. Laser range finder is used for mapping of obstacles and driving environment in the 2D laser plane. Rotary encoders are used for localization of UGV. The main contributions of this research are the development of an algorithm for global 2D map building and it will turn a UGV navigation based on map matching into a possibility. In this paper, a map building algorithm will be introduced and an assessment of algorithm reliability is judged at an each environment.

The purpose of this research is to develop stereotactic localization and radiation measurement system for the efficient and precise radiosurgery. The algorithm to obtain a 3-D stereotactic coordinates of the target has been developed using a Fisher CT or angio localization. The procedure of stereotactic localization was programmed with PC computer, and consists of three steps: (1) transferring patient images into PC; (2) marking the position of target and reference points of the localizer from the patient image; (3) computing the stereotactic 3-D coordinates of target associated with position information of localizer. Coordinate transformation was quickly done on a real time base. The difference of coordinates computed from between Angio and CT localization method was within 2 mm, which could be generally accepted for the reliability of the localization system developed. We measured dose distribution in small fields of NEC 6 MVX linear accelerator using various detector; ion chamber, film, diode. Specific quantities measured include output factor, percent depth dose (PDD), tissue maximum ratio (TMR), off-axis ratio (OAR). There was small variation of measured data according to the different kinds of detectors used. The overall trends of measured beam data were similar enough to rely on our measurement. The measurement was performed with the use of hand-made spherical water phantom and film for standard arc set-up. We obtained the dose distribution as we expected. In conclusion, PC-based 3-D stereotactic localization system was developed to determine the stereotactic coordinate of the target. A convenient technique for the small field measurement was demonstrated. Those methods will be much helpful for the stereotactic radiosurgery.

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.
