We investigated the actual usefulness of bathrooms in individuals living in apartment. We performed a randomized matched questionaire study involving 487 individuals who use a unit-bathroom and live in apartment in Taegu and it's rural cities for the period from May to June, 2000. Most of the individuals used bathroom for washing behavior of daily living, such as, washing hands, feet, face, and hair, except bathing, Almost all the individuals reported some complaints about the height and size of wash-stand when they wash face or hair, And most of the individuals does not use the bath-tube when they shower or bathe.

This paper develops the dynamic equivalents program combined with graphic user interface(GUI), to solve the stability of large power system. The p개posed method is coherency-based dynamic equivalents for transient stability studies. The program also provides with pull-down menu and Hangout help information for users. The developed dynamic equivalents program is suitable for the transient stability studies of a large power system with lots of data. The dynamic equivalents demonstrated over the New England system with 39 buses and 10 generators.

This paper presents an approach based on knowledge models to detect and isolate faults in a voltage source inverter. These faults do not affect the existing system protections. A diagnosis system which uses only the input variables of the drive is presented. It is based on the analysis of the current-vector trajectory and of the instantaneous frequency in faulty mode. These two methods have been verified in simulation results.

An unwanted trip of backup distance relays often lead to a blackout. This paper presents investigation report on involvement of backup distance relays in the past blackouts and sensitivity-factor based algorithm to make a distinction between a fault and overload caused by line tripping. A preliminary idea to prevent deterioration of the situation due to unwanted trip of distance relays by utilizing the proposed algorithm is presented.

본 논문에서는 10Mbps 뿐만 아니라 100Mbps를 지원하는 패스트 이더넷 제어기인 LAN-100 IP 모듈 개발과 물리 계층에 대한 인터페이스인 LN-100 어댑터에 대해 논한다. LAN-100 IP 모듈은 10Mbps 및 100Mbps 속도를 지원하는데 이를 위해 SMC사의 Feast 91C100 Fast Ethernet controller를 사용하였다. 따라서 본 논문에서 주로 다루고자 하는 내용은 이 이더넷 칩의 디바이스 드라이버 개발에 관해서이다. 즉, 이더넷 초기화 과정과 이더넷 송신부 및 수신부 그리고 인터럽터 처리에 대해 논한다. 또한 개발된 드라이버의 송수신 성능에 관한 내용도 함께 다룬다.
