  • A patient treated with venlafaxine for major depression developed an interstitial lung disease (ILD) with the characteristic clinical, radiological and pathological features of chronic hypersensitivity pneumonitis. A high resolution computed tomography scan demonstrated ground glass opacity, mosaic perfusion with air-trapping and traction bronchiectasis in both lungs. The pathological findings were consistent with a nonspecific interstitial pneumonia pattern. Clinical and radiological improvements were noted after the discontinuation of venlafaxine and the administration of a corticosteroid. This report provides further evidence that the anti-depressant venlafaxine can cause ILD.

  • In this study, we manufactured polymer-LED using light emitting copolymer as the active layer. After cathode layer deposition, we did post-annealing at $150^{\circ}C$ during 10 min in $N_2$ glove box. Then, we confirmed that the efficiency of the device was significantly enhanced by post annealing process. Its value was increased from 0.18(cd/A) to 1.32(cd/A), approximately 7 times. This phenomenon is a result of improved stability between polymer and metal cathode for injection of electrons as the contact density increases.

  • Anthracene derivatives, 9,10trimethylsilylanthr - acene(SA) and bis(2-phenylethynyl)trimethylsilyl anthracene(Si-BPEA) were synthesized and their emission properties were studied with UV and PL spectrometers. The PL maxima of anthracene, SA, bis(2-phenylethynyl)anthracene (BPEA), Si-BPEA were obtained at 401, 438, 475, 478nm, respectively. The electro-optical properties OLED devices made with these anthracene derivatives were discussed.

  • 본 논문에서는 PSIM 모델을 이용하여 오프라인 전류모드 제어 플라이백 변환기의 동특성 해석과 제어기 설계방법을 제시하였다. 제시된 PSIM 모델은 시간영역 모델을 이용하기 때문에 구조가 간단하여 이용하기가 쉬우며 정확성이 높다는 장점이 있다. 그리고 $110V{\sim}220V$ 오프라인 전원을 입력하여 10V/5A의 출력을 가지는 50W 플라이백 변환기를 설계 제작하여 실험을 통해 확인하였다.
