Effects of physicians’ certification behaviors on under- or overestimation of diabetes mortality
Tsung-Hsueh Lu

Cause-specific mortality is the most frequently used end point of health outcome in clinical trials or prognostic studies. If the cause-specific mortality was underestimated or overestimated, the derived conclusions were biased. The under- or overestimation of cause-specific mortality is highly associated with the physicians’ cause of death certification behaviors. One of the difficulties in ...

An assessment of technology-based service encounters and network security on the e-health care systems of medical centers in Taiwan
Hsin-Hsin Chang

As a majority of studies have examined technical aspects of constructing an electronic medical record system and an online appointment system; the balances have been aimed at understanding the current state of the systems. This study implemented the Service Encounters Evaluation Model (Bitner, 1990), the European Customer Satisfaction Index (Fornell, Johnson, Anderson, Cha, & Bryant, 1996), the ...

The Dispersion Characteristics of Sonic Crystals Consisting of Elliptic Cylinders
Lien-Wen Chen

Acoustic or elastic wave propagation in sonic or phononic crystals had been the subject of intense investigation in recent years. The normal incident dispersion characteristics of a sonic crystal which consisting of elliptic cylinder have been investigated. The 2D triangular sonic crystal with steel elliptic rods in the air background are studied, where ρsteel = 7800 kg/m3 ...

Electrically switchable and optically rewritable reflective Fresnel zone plate in dye-doped cholesteric liquid crystals
Andy Y.-G. Fuh

Lenses based on binary-type Fresnel zones are called Fresnel lenses. The Fresnel zones are formed by concentric circles in such a way that the radius rm of the mth zone satisfies , where  is the radius of the innermost zone. Obstructing the odd zones (or even zones) of the Fresnel zones, we get the Fresnel zone plate, which can function as a lens with the primary focal ...

Highly ESD reliable nitride-based heterostructure p-i-n photodetectors with a p-AlGaN blocking layer
S. J. Chang

For nitride-based devices prepared on sapphire substrates, it is known that electrostatic discharge (ESD) is a serious problem. Nitride-based PDs also suffer from ESD, particularly when operated at high-temperature and/or high-humidity conditions [1]. Very recently, it has been shown that one can combine a Si complementary-metal-oxide-semiconductor (CMOS) chip with a nitride-based Schottky ...
