Strategies for oral health care for people with disabilities in Taiwan
No full text[[abstract]]Oral health care for disabled patients is an important health issue in Taiwan. Disabled patients seeking dental care include those with mental retardation, cerebral palsy, epilepsy, Down syndrome, autism, xerostomia, AIDS, toss of function of major organs, and neurologic diseases. Current dental health care policies do not completely address this critical oral health issue. Most of these physically or mentally disabled patients cannot find suitable or qualified dental services in local dental clinics or even hospitals. Our current health care insurance system should provide greater benefits for dental practitioners who are witting to care for such disabled patients. The Department of Health (DOH) should legislate policies to provide greater financial support and equipment and encourage hospital dental clinics and dentists to join this special oral care program. Dental schools, hospitals, and the DOH can also provide curricula and special training programs for both dentists and undergraduate dental students so that they can learn about diseases and dental care of these patients. The government and DOH should cover the fees of lawsuits if dentists have medical legal problems white treating patients with disabilities. Questions on special care dentistry can possibly be included in the National Board Dental Examination. The government can establish some national oral health care centers to treat these disabled patients. Through the development of effective preventive and treatment strategies, the incidence of oral diseases in these patients can be reduced in the future
Synthesis optimization and charge carrier transfer mechanism in LiLuSiO<sub>4</sub>:Ce, Tm storage phosphor
No full textLiLuSiO4:Ce and LiLuSiO4:Ce, Tm show very efficient charge carrier storage properties upon beta irradiation after samples have received treatment in vacuum. They outperform the commercial storage phosphor BaFBr(I):Eu2+ in many aspects. The influence of the synthesis conditions, Ce and Tm concentration, nonstoichiometry and codoping with Ca, Hf, Al and Ge are reported. Based on the results of the synthesis optimization, thermoluminescence (TL) emission and TL excitation spectra a mechanism of charge carrier transfer, storage, and recombination during irradiation and thermal or optical readout is proposed.Accepted Author ManuscriptRST/Fundamental Aspects of Materials and EnergyRST/Luminescence Material

Simulation on Liquid Crystal Tuned Tamm Plasmonic Device
No full textTamm surface plasmon wave is a surface wave that is confined to the interface between a metal and a one-dimensional photonic crystal, it can be produced by both TM amd TE polarization at any incident angles.
In this paper, a device consisted of liquid crystal and distributed Bragg reflector is simulated by using Transfer Matrix Method. First, calculating reflection and transmission coefficient in liquid crystal layer by using electromagnetic boundary conditions. Second, calculating reflectivity by using interface and propagation matrix. Next, when liquid crystal is tuned angle, we analyze refleciotn, band gap and field diagram in simulation. Finally, we discuss the relationship that is between resonance wavelength and Tamm plasmon wave, furthermore, we change the thickness in other layers and discuss their influence to resonance wavelength. In conclusion, this research confirms Tamm Plasmonic device experiment result (NCTU, Dr. Jeng, Shie-Chang) and discuss them

Level 1 Collection 1 data was provided by the United States Geological Survey (USGS)'s Earth Resources Observation and Science (EROS) Center.<b>BACKGROUND</b><br/><p><br/><p>The United States Geological Survey's (USGS) Landsat satellite program has been capturing images of the Australian continent for more than 30 years. This data is highly useful for land and coastal mapping studies. <br/><p>In particular, the light reflected from the Earth’s surface (surface reflectance) is important for monitoring environmental resources – such as agricultural production and mining activities – over time. <br/><p>We need to make accurate comparisons of imagery acquired at different times, seasons and geographic locations. However, inconsistencies can arise due to variations in atmospheric conditions, sun position, sensor view angle, surface slope and surface aspect. These need to be reduced or removed to ensure the data is consistent and can be compared over time. <br/><p> </p><br/><b>WHAT THIS PRODUCT OFFERS</b><br/><p><br/><p>GA Landsat 5 TM Analysis Ready Data Collection 3 takes Landsat 5 Thematic Mapper (TM) imagery captured over the Australian continent and corrects for inconsistencies across land and coastal fringes. The result is accurate and standardised surface reflectance data, which is instrumental in identifying and quantifying environmental change. <br/><p><br/><p>The TM instrument is an advanced, multispectral scanning, Earth resources sensor which is designed to categorise the Earth's surface. It is particularly useful for agricultural applications and identification of land use. <br/><p><br/><p>This product is a single, cohesive Analysis Ready Data (ARD) package, which allows you to analyse surface reflectance data as is, without the need to apply additional corrections. <br/><p><br/><p>It contains three sub-products that provide corrections or attribution information:<br/><p><br/><p> 1) GA Landsat 5 TM NBAR Collection 3 <br/><p> 2) GA Landsat 5 TM NBART Collection 3<br/><p> 3) GA Landsat 5 TM OA Collection 3<br/><p><br/><p>The resolution is a 30 m grid based on the USGS Landsat Collection 1 archive
The dependence of light extraction improvement on optimized surface microstructure for AlGaN-based UVC-LEDs considering TM-polarized emission
No full textIn order to improve the light extraction of AlGaN-based short wavelength ultraviolet light emitting diodes (DUC-LEDs), a type of microstructure with high aspect ratio is introduced and optimized on the AlN substrate surface. And, particle swarm optimization (PSO) algorithm is used to inverse design of the surface microstructure to maximize the light extraction efficiency (LEE). Considering that the propagation characteristics of TM-polarized light are different from that of TE-polarized light, the optical field distribution and LEE is analyzed for the UVC-LEDs with different TE-polarized component when the optimized surface microstructure is applied. Furthermore, the preparation process tolerance of the high aspect ratio structure is discussed by calculating the LED's LEE when the structural deviation occurs or morphology changes. Simulation results show that, by using the optimized surface microstructure based on parabola cone array, the LEDs' LEE is increased from 4.4% to 8.7% and from 0.4% to 3.7% for TE-polarized and TM-polarized emission, respectively. In addition, it is demonstrated that the light extraction improvement by the surface microstructure has a good tolerance to the structural deviation and morphology. The results are significant for improving light extraction and realizing high efficient short wavelength AlGaN-based UVC-LEDs by designing surface microstructures.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ImPhys/Esmaeil Zadeh grou
