To explore the relationship between baseline information, personal factors, working characteristics and job performance among nurses in emergency department in northern Taiwan.Two-hundred twenty-two nursing staff were interviewed repeated with structured questionnaires for data collection in 3 time points (From August to September, 2008, from February to March, 2009, and from November to December, 2009). The generalized estimating equation (GEE) is used to test the relationship between the domains of independent variables (baseline information, personal factors, working characteristics) and dependent variables (task performance, contextual performance).

As the competition in the Taiwanese medical industry becomes increasingly fierce, public hospitals are confronted with challenges in orientation and operations. This study measured changes in the operational efficiency of public and their competitors, non-public hospitals, in Taiwan. This study considered differences in technology and scale between public and non-public hospitals and adopted the quality-incorporating metafrontier Malmquist productivity index to analyze inputs, outputs, and quality achievements of hospitals.

The structural characterization correlated to the processing control of hierarchical structure of planar heterojunction perovskite layer is still incomplete due to the limitations of conventional microscopy and X-ray diffraction. This present study performed the simultaneously grazing-incidence small-angle scattering and wide-angle scattering (GISAXS/GIWAXS) techniques to quantitatively probe the hierarchical structure of the planar heterojunction perovskite solar cells. The result is complementary to the currently microscopic study.

Background: Developing countries are confronting a steady growth in the prevalence of the infectious diseases. Mobile technologies are widely available and can play an important role in health care at the regional, community, and individual levels. Although labs usually able to accomplish the requested blood test and produce the results within two days after receiving the samples, but the time for the results to be delivered back to clinics is quite variable depending on how often the motorbike transport makes trips between the clinic and the lab.
