전문적인 작업의 복잡한 절차 때문에 컴퓨터를 사용하는데 어려움이 있다. 이러한 문제 있어서 인터페이스 환경을 보다 인간 중심적으로 설계하는 절차를 제안하였고, 보호계전기 정정 프로그램 환경에 보다 쉽고, 사용하기 쉬운 사용자 인터페이스를 구현하였다.

The distribution system is operated radially in which electrical grid is complex. If a fault occurs in distribution system, it can make a huge impact on power supply. Therefore, The distribution contingency analysis is proposed in this paper based on the reference [1]. Using RSI (Restoration Section Index) calculated by feeder margin and section load, the operator can grasp restoration capability quickly.

This paper describes an experimental results to analyze the dynamic characteristics of STATCOM, which is connected to the ac system for improving the voltage stability. The experimental results confirms that the scaled model for STATCOM operates correctly by the conceived control algorithm and properly compensates and regulates the bus voltage at the common connection point.

China has countless ancient books that contain thousand years of continuously recorded history across every generation. It is essential to organize the ancient cultural literature in order to better communicate. The study of ancient Chinese literature recently has become a subject of priority. Shi-Ji, one of the representative documents, is used for record keeping because of its experience with ancient Chinese historic materials and artifacts. This draft of Shi-ji is based on ancient Chinese research methods with the purpose to explore the character, phonology, syntax, exegesis and collation of historical value.

In 1911, Dubouis determined all positive integers represented by sums of k nonvanishing squares for all k ≥ 4. As a generalization, Y.-S. Ji, M.-H. Kim and B.-K. Oh determined all positive definite binary quadratic forms represented by sums of k nonvanishing squares for all k ≥ 5. In this article, we give a simple proof for Ji-Kim-Oh's theorem for all k ≥ 10.
