  • The study aims to investigate general characteristics of Jae-sil from an architectural perspective by grasping location, deployment, structure, and plan composition based on existing inhabited conditions in Jeollabukdo. Results derived from the study are as follows. First, the location of Jae-sil is classified into mountainous and village types, and the two types showed a similar distribution. The village type showed the most distribution in the foot of a mountain in the rear of village, while the mountainous type is close to graveyard. The Jae-sil were mostly exposed to south, southeast, and southeast, which was not significantly different from residence. For deployment of the Jae-sil, a "二" shaped house, where main quarter and gated building are parallel located, can be common, indicating that additional attached building is less required. Second, for the platform out of structural components, coursed masonry was conducted by using natural rocks, and placed were a prop on the platform, first line on processed foot stone, and others on natural foot stone. For pillar, front line round columns, while others square columns. The binding type of the upper part of pillar is dominated by jangyeosujang and sorosujang. For wooden frame structure, 5ryangs were the most distributed, and out of these, 1goju 5ryang was the most generally used. For a roof part, it was composed with gambrel roof with single eave, and the roof was constructed by placing traditional Korean tile roof on the top. Third, for a size of Jae-sil out of plan composition, although the facade and the side of it were presented in a diverse manner, 4 facade rooms and 1.5 side rooms were the most frequently presented, and all Jae-sil were equipped with front ceremonial space. For spatial composition of Jae-sil, main floored hall is placed at the center, and each room is placed on the left and right side to secure space for ancestral rite for participants of it, and for a house with 5 rooms or more, it shows that main floored hall and rooms are weighted from side to side.

  • This paper presents new diagnosis technique for detecting a partial discharge(PD) using antenna. The wavelet transform is applied for the analysis of PD pulse signal because it is difficult to identify PD signal using electromagnetic waves detected by antenna. The capabilities of the proposed diagnosis methodology for detecting PD signal is verified on experiment in laboratory.

  • The increase of fault current due to larger power demand has caused the capacity of power machines in grid to increase. To protect the power system effectively from the increased fault current, the superconducting fault current limiter (SFCL) have proposed one of several countermeasures. Therefore, to introduce SFCL into power distribution system, the position of SFCL in power distribution system is selected among some cases. Each position changes fault current limiting characteristics and SFCL's requirement. In this paper, the characteristics of limiting fault current according to installed SFCL's location in power distribution system.

  • The increase of fault current due to large demand has caused the capacity of power machines in power grid to increase. To protect the power system effectively from the large fault current, several superconducting fault current limiters have been proposed. however, in order to apply superconducting fault current limiters into power system, there are many problems such as cost, recovery, AC loss, and cryogenic. In order to solve these problems, hybrid superconducting fault current limiter(HSFCL) was proposed. However, HSFCL also has a problem that is protective coordination in distribution system with HFSCL. In this paper, HSFCL limiting after half cycle modeled and analyzed about protective coordination.

  • 무인기 개발 시 항공전자시스템의 요구도 검증을 위해 통합시험능력을 제공하는 통합시험환경(SIL)을 개발하였다. 개발된 SIL은 유인항공기 SIL이 보유하고 있는 기능들을 기본적으로 제공하며, 각 구성품인 지상제어 모의, 비행체 모의, 비행환경 모의가 폐루프(Closed-Loop)로 연동되는 구조 하에서 시험 데이터의 가시화 및 시험자동화에 중점을 두고 설계되었다. 이로써 무인기의 복잡하고 수많은 요구도가 개발된 SIL을 통해 간편하고 정확하게 검증될 수 있었다. 개발된 SIL은 4단계의 검증과정을 통해 기능 및 성능의 정확성과 신뢰성이 검증되었으며, 무인기 지상체 및 비행체 통합을 위한 체계 SIL에서도 정상 동작함을 확인하였다.
