Power scaling of continuous-wave second harmonic generation in a MgO:PPLN ridge waveguide and the application to a compact wavelength conversion module.

The power scaling of continuous-wave (CW) second harmonic generation (SHG) in a MgO:periodically poled lithium niobite (PPLN) ridge waveguide is investigated. The nonlinear coefficient and propagation loss factors of the MgO:PPLN waveguide are verified for future reference. The MgO:PPLN waveguide structure is determined according to a practical fiber coupling configuration, as well as the theoretical model of output power characteristics.

Improving self-care efficacy and quality of life with a self-management program among patients with chronic obstructive pulmonary disease: A quasi-experimental study.

Self-management helps patients understand their illnesses and learn about disease-related skills so they can better manage their situation. However, published studies on the effectiveness of self-management for chronic obstructive pulmonary disease (COPD) are heterogeneous. Quasi-experimental design was used to investigate the effectiveness of a self-management program in self-care efficacy and quality of life in patients with COPD.

Risk factors associated with physical restraints in residential aged care facilities: a community-based epidemiological survey in Taiwan.

Aim: To identify the rate and risk factors of physical restraint in residential aged care facilities in Taiwan.

Background: In Taiwan, physical restraint is commonly used in aged care facilities to prevent accidents. Many are unaware of the associated risks.

Fabrication of an asymmetric Bragg coupler-based polymeric filter with a single-grating waveguide.

In this work, a first report on fabricating an asymmetric Bragg coupler-based filter on polymeric waveguides without input-waveguide grating was revealed. The fabrication process we developed was using holographic interference techniques, capillary effect, soft lithography, and micro molding process. The transmission dip of about -9.

Community-based interventions to reduce falls among older adults in Taiwan - long time follow-up randomised controlled study.

Aims: The aim of the study was to examine the effects of different interventions that are used to prevent falls. These were education, Tai Chi Chuan and education plus Tai Chi Chuan; the study involved a five-month implantation period and a one-year follow-up period.

Background: With advancing years, a fall can be very serious and an increased number of falls/re-falls among older adults has been noted.
