After reviewing previous work done on major piezoelectric thin films such as PZT and ZnO, ZnO thin piezofilm with a thickness of 1∼3μm is fabricated by sputtering on the different substrates(i.e., P^+-Si/N-Si, SiO_2/P^+-Si/N-Si, Al/SiO_2/P^+-Si/N-Si). The result shows that ZnO piezofilm on the Al has the best c-axis orientation. One of applications for the ZnO piezofilm as a microvalve to control liquid flow is introduced, and which can be controlled electrically and remotely.

There are presently only two licensed therapies for treating liver disease caused by infection with the hepatitis B virus (HBV). These are interferon-alpha and lamivudine. Neither agent was specifically developed as an antiviral compound for treating patients infected with HBV. Both therapies are limited in the clinic by a low response rate and in the case of lamivudine, selection of drug-resistant mutants, whilst troublesome side effects limit the use of interferon-alpha. Several promising nucleoside/nucleotide analogues are undergoing clinical trials, including adefovir dipivoxil and entecavir, both of which appear to be active against lamivudine-resistant HBV. In addition to these nucleoside/nucleotide analogues, it will be important to develop new agents with different modes of action, which can be added to the antiviral cocktails that will be required to adequately suppress and hopefully eliminate HBV replication.

정온도형 전자식 반도체 유속/유량계(電子式 半導體 流速/流量計)는 기해 및 액체의 유동을 정밀하게 측정하고 소형화할 수 있는 유속/유량계이다. 그러나 정온도형 유속/유량계는 유체의 온도가 변화할 경우 저항에서 소모되는 발열량이 변화하여 센서를 오동작시키는 등의 여러 가지 문제점들을 가지고 있다. 따라서 본 연구에서는 온도 보상을 독특한 센서 구조와 회로를 설계하여 해결하였고 유한차분법을 이용한 simulator를 개발하여 이론적 분석도 병행하였다. 또한 실험 장비를 제작하고, 8bit Z80 CPU를 이용하여 전체 시스템의 크기를 소형화할 수 있는 온도 보상된 디지탈 유속/유량계에 대하여 연구하였다. A constant temperature solid-state flowmeter can measure precise velocity of gas and liquid, and can be made in a small size. However, several .difficulties exist, including that power consumption at the sensor is variable as fluid temperature varies. Therefore, in this study a special sensor structure and circuit in order to solve the problem of temperature compensation are designed, and a simulator using finite differential method as theoretical analysis are developed. An experimental apparatus are manufactured and digital flowmeter which is enable to miniaturize the system using a 8-bit Z80 CPU are studied.
