The organization for satellite operation team is mainly based on the number of satellites to be controlled, operator's workload of payload operation support and the degree of automation of the operation system. Although the structure and its functionality of satellite operation organization are a little different according to the complexity of the operation, most satellite control centers have adapted the similar architecture for single or multiple satellite support. KARI Satellite Operation Center(KSOC) has started its simple mission operations since the launch of KOMPSAT-1(21st Dec. 1999) and has been evolving into multiple mission operations for various satellites such as KOMPSAT-2, KOMPSAT-3, KOMPSAT-5 and COMS(Communication Ocean Meteorological Satellite). This paper presents the appropriate direction of future deployment for KSOC by comparing the current status with the recommendation of the advanced satellite operation organization and analyzing their experiences in order to propose the better solution for efficient and safe satellite operations.

The purpose of this study is to diagnose problems of the permanent judge system by examining the cases of practical running of the permanent judge system, and to provide basic materials for the settlement of fair and transparent judge culture. The findings of the case studies are as follows. First, the difficulties in selection, allocation, and education of judges caused by the operation of the permanent judge system. The problems in allocation are forceful allocation, conflict over allocation with general judges. The problems in evaluation are individual evaluation and limits of fairness, lack of evaluation rules. Second, the unpredictability of whether the permanent judge system survive or not. Third, there are some environmental constraints of the permanent judge system. Lack of protective apparatus is lack of rescue method and solution for intentional protest. Forth, there is a problem of low recognition of the permanent judge system. As the federation has been not active in publicizing the permanent judge system, the system is not well known.
