Low-Temperature Growth of Well-Aligned ZnO Nanorods by Chemical Vapor Deposition
Jih-Jen Wu

One-dimensional (1-D) nanometer-sized semiconductor materials have attracted considerable research activities because of their great potential for fundamental studies of the roles of dimensionality and size in their physical properties as well as for applications in optoelectronic nanodevices and functional materials.  ZnO is a versatile material and has been used considerably for its catalytic, …

The simultaneous use of weighted logrank and weighted Kaplan-Meier statistics with clustered right-censored data
Yunchan Chi

Clustered right-censored data often arise from tumorigenicity experiments and clinical trials. For example, in an otology study, 78 children with both ears suffering from otitis media are randomly assigned into the treatment group or control group to place ventilating tubes in both ears to reduce the prevalence of middle ear effusion. The goal of such a study was to examine whether postsurgical …

A Brief Fatigue Inventory of Shoulder Health Developed By Quality Function Deployment Technique
Shuo-Fang Liu

The purpose of this study was to develop a diagnostic outcome instrument that has high reliability and low cost. The scale, called the Shoulder Fatigue Scale-30 Items (SFS-30) risk assessment, was used to determine the severity of patient neck and shoulder discomfort.

The quality function deployment (QFD) technique was used in designing and developing a simple medical diagnostic scale with …

Low Dielectric Loss Ceramics in the ZnAl2O4–TiO2 System as a τf Compensator
Cheng-Liang Huang

In the last few decades, the microwave-based wireless communications industry has been revolutionized by using the ceramic dielectric materials to reduce the size and the cost of components in circuit systems due to their unique electrical properties. In particular, size reduction is mainly a result from the use of high-dielectric-constant material since the wavelength (λ) in dielectrics …
