Proposed EEFL inverter design method with Dimming control to use microprocessor. Reduce power loss using Energy Recovery method, and design inverter control program that use RS-232 communication. Also, low temperature driving time shortened 50% that use duty variable control.

Long period eclipsing binary 32 Cygni was photometrically observed in 1992 at Yonsei University Observatory. Instrumental differential magnitude and standardized magnitude of this star show some intrinsic light variations. Some possible explanations will be discussed. BVRI photometric observations show that 30 Cyg may be a variable star. A further monitoring of 30 Cyg is therefore called for justification of such evidences.

자연성 종격동 기종은 젊은 연령에서 주로 직접적인 이유가 없이 발생되는 흔치 않은 질환으로 응급실에서 급성 흉통의 원인으로 감별해야할 질환중의 하나이다. 간혹 응급상황이 발생하여 응급 처치를 받을 수 있다고 하지만 대부분에서 보존적인 치료로 호전이 되는 양호한 질환이기도 하다. 저자들은 15세 남자에게 특별한 유발 요인이 없이 발생하였고 입원치료 없이 응급의료 센터에서 바로 퇴원한 자연성 종격동 기종 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

This note is concerned with the use of incomplete weights in multiple criteria decision making. In an earlier study, an optimistic use of incomplete weights is developed to prioritize decision alternatives, which applies the most favorable set of weights to the alternative to be evaluated. In this note, we develop a method for a pessimistic use, thereby applying the least favorable weight set to the evaluated alternative. This development makes possible a more detailed prioritization of competing alternatives, and hence enhances decision-making powers.
