  • The Taiwanese liquid crystal display (LCD) industry has traditionally produced a huge amount of waste glass that is placed in landfills. Waste glass recycling can reduce the material costs of concrete and promote sustainable environmental protection activities. Concrete is always utilized as structural material; thus, the concrete compressive strength with a variety of mixtures must be studied using predictive models to achieve more precise results. To create an efficient waste LCD glass concrete (WLGC) design proportion, the related studies utilized a multivariable regression analysis to develop a compressive strength waste LCD glass concrete equation. The mix design proportion for waste LCD glass and the compressive strength relationship is complex and nonlinear. This results in a prediction weakness for the multivariable regression model during the initial growing phase of the compressive strength of waste LCD glass concrete. Thus, the R ratio for the predictive multivariable regression model is 0.96. Neural networks (NN) have a superior ability to handle nonlinear relationships between multiple variables by incorporating supervised learning. This study developed a multivariable prediction model for the determination of waste LCD glass concrete compressive strength by analyzing a series of laboratory test results and utilizing a neural network algorithm that was obtained in a related prior study. The current study also trained the prediction model for the compressive strength of waste LCD glass by calculating the effects of several types of factor combinations, such as the different number of input variables and the relevant filter for input variables. These types of factor combinations have been adjusted to enhance the predictive ability based on the training mechanism of the NN and the characteristics of waste LCD glass concrete. The selection priority of the input variable strategy is that evaluating relevance is better than adding dimensions for the NN prediction of the compressive strength of WLGC. The prediction ability of the model is examined using test results from the same data pool. The R ratio was determined to be approximately 0.996. Using the appropriate input variables from neural networks, the model validation results indicated that the model prediction attains greater accuracy than the multivariable regression model during the initial growing phase of compressive strength. Therefore, the neural-based predictive model for compressive strength promotes the application of waste LCD glass concrete.

  • The purpose of this study is to investigate the opacity and printing strength of MG paper overlaid plywood. The printing strength of ink on MG paper can be evaluated effectively by a formula $E^{*2}=[(L^{*})^{2}+(a^{*})^{2}+(b^{*})^{2}]^{1/2}$ that we proposed. Higher E value indicates good printing strength of ink-on-paper. We also assess the real color of translucent printed MG paper with a formula CIE ${\bigtriangleup}E^{*}$ (color difference between a pile of same paper to be opaque and fancy paper laminated board). In addition, the color difference on paper surface caused by the color of wood-based board (bottom) can be evaluated by a formula of Pc. No. Generally, an acceptable appearance quality of fancy boards is ${\bigtriangleup}E^{*}$ <2.0 and small Pc.No. value. The experimental results showed that Japan-made MG papers -J1, J2 and J3 have better printing strength and gloss than that of Taiwan-made paper (T1). The reason for this was that Taiwan-made paper has poor printing strength and low gloss, which might be correlated to the fiber compositions in paper. Higher printing strength can be seen for short fiber containing handsheets when comparing to that of handsheets. Nonetheless, low-freeness sheets gives better printing strength than that of high-freeness sheets. High-opacity MG paper gives good opacifying effect to the fancy paper laminated wood-based boards. Comparing the surface color of 2 kinds of fancy paper laminated boards, paperboard T1 laminated with high-opacity fancy paper showed slight color difference. The same results can be seen for $??g/m^{2}$ handsheets. Higher-opacity Acacia and Eucalyptus bleached sulfate pulps (short fiber) gives higher opacifying effect on the plywood when comparing to Northan pine and Radiata pine sulfate pulps(long fiber). The former ones also showed small color differences when comparing the color differences between the color of fancy paper and laminated paper board. Additionally, the color of bottom plywood can't be shown through for the high-opacify surface paper adhered to. Besides, the PC No of the base paper laminated board is small as well. Apparently, we can add colorants to the binders for the manufscture of various handsheets ($30g/m^{2}$) with various pulp mix ratios to increase the opacity of paperboards to certain extents. When we using yellow and brown binders in paper laminated board, the color difference between Acacia and Eucalyptus handsheets overlaid boards decreasing to 2.0 (acceptable ${\bigtriangleup}E^{*}$ <2.0, hard to discern), but not much improvement for Northern and Radiata pines. Definitely, show-through defects can be discernible for lower opacity papers. In general, admirable printing strength of fancy paper by which glued to plywood can be made with high-opacity paper and colored binders techniques.

  • The prevalence of Enterobius vermicularis infection among preschool children was reported to be low based on a 5-year screening program in Taipei City, Taiwan. The Taipei City government intended to terminate the E. vermicularis screening program among preschool children. Thus, we were entrusted with confirming whether pinworm infections among preschool children in Taipei City had truly declined. From each of 12 administrative districts 2-3 kindergartens were randomly selected for investigation. In total, 4,349 children were examined, of which 2,537 were boys and 1,812 were girls. The cellophane tape adhered to a glass slide was used, and all examinations were done by certified medical technologists. Results indicated that the overall prevalence rate of pinworm infections was 0.62% (27/4,349). Although the infection rate was higher among boys (0.67%, 17/2,537) than in girls (0.55%, 10/1,812), no significant difference was found ($X^2$=0.399, P=0.62). According to the administrative district, the infection rate ranged from no positive cases of E. vermicularis infection in the Xinyi, Zhongzhen, and Wanhua Districts (0%; 0/299, 0/165, and 0/358, respectively), to 0.26% (1/131) in Songshan District, with the highest rate of 1.88% (7/373) in Wenshan District. Because the overall infection rate (0.62%, 27/4,349) in the present study was unchanged compared to that (0.40%, 197/49,541) previously reported in 2005, we propose that regular pinworm screening and treatment programs should be continued in some parts of Taipei City.

  • The purpose of this study was to present a new research method of stage costume by designing and making the stage costume of Yean-GaeSoMoon(淵蓋蘇文) in Peking Opera Du Mu Guan (Korean; Dog Mog Guan, 獨木關). The stage costume of Peking Opera was formed on the basis of the Chinese traditional stage costume in the Qing period, however the style of stage costume was beautified the costume of Ming period and here contained the factors of successive costumes. But the stage costume of Peking Opera didn't have the same rank system with real history costume and didn't have demarcation according to period and history. In the stage costume of Peking Opera, the color is cultural language that can inform spectators of sex, age, personality, position of characters. The pattern of decoration also symboled the personality and characteristic of the character. Yean-GaeSoMoon in the play wore green armour (Chinese; ru ying kao 綠硬靠), red pants (Chinese; hong ku 紅褲), red mustache (Chinese; hong ran kou 紅髥口), crown (Chinese; da e zi 大額子), shoes (Chinese; hou di xue 厚底靴) and Xue RenGui wore white armour (Chinese; baikao 白靠), red pants (Chinese; hong ku 紅褲), shoes (Chinese; hou di xue 厚底靴), hat (Chinese; za jin 扎巾). By historical materials, Yean-GaeSoMoon was a nationalist who uphold national sprit and the greatest hero of the age and a charismatic politician who combines literatural arts with military arts. Considering these reviews, defined the thema of his new costumes' image as "the flying bird which has three legs"(三足鳥), the bird which symbolized the sun and immortality in Koguryo fresco. On the basis of this image, presented three types of Yean-GaeSoMoon's stage costume. Yean-GaeSoMoon as the minister in the court wore black gown (Chinese; mang pao 蟒袍) of dargon pattern which symbolizes harisma who opening the heaven. He as the general who directs war wore red mantle (Chinese; dou peng 斗蓬) which symbolizes the blue dragon that soaring into the sky, as the officer who fights the enemy's general wore green armour (Chinese; gai liang jia 改良甲), red pants (Chinese; hong ku 紅褲) which symbolizes the flying Sward that blowing violently. By wearing these stage costumes, the image of Yean-GaeSoMoon could changed from the fierce general of minority race who likes to fight, to the Koguryo general who fights against enemy at the risk of his life for Koguryo's autonomy. Through this study once again we could realized that stage costume played very mportant part In outstnding the characteristic of actor in the Peking Opera.

  • Objective: Hospitalization of patients with delirium after visiting the emergency department (ED) is often required. However, the readmission risk after discharge from the ED should also be considered. This study aimed to explore whether (i) immediate hospitalization influences the readmission risk of patients with delirium; (ii) the readmission risk is affected by various risk factors; and (iii) the healthcare cost differs between groups within 28 days of the first ED visit. Methods: Using the National Health Insurance Research Database, the data of 2,780 subjects presenting with delirium at an ED visit from 2000 to 2008 were examined. The readmission risks of the groups of patients (i.e., patients who were and were not admitted within 24 hours of an ED visit) within 28 days were compared, and the effects of the severities of different comorbidities (using Charlson's comorbidity index, CCI), age, gender, diagnosis and differences in medical healthcare cost were analyzed. Results: Patients without immediate hospitalization had a higher risk of readmission within 3, 7, 14, or 28 days of discharge from the ED, especially subjects with more severe comorbidities ($CCI{\geq}3$) or older patients (${\geq}65years$). Subjects with more severe comorbidities or older subjects who were not admitted immediately also incurred a greater healthcare cost for re-hospitalization within the 28-day follow-up period. Conclusion: Patients with delirium with a higher CCI or of a greater age should be carefully considered for immediate hospitalization from ED for further examination in order to reduce the risk of re-hospitalization and cost of healthcare.

  • Objective: The aim of this study was to investigate diffusion tensor (DT) imaging-derived properties of benign oligemia, true "at risk" penumbra (TP), and the infarct core (IC) during the first 3 hours of stroke onset. Materials and Methods: The study was approved by the local animal care and use committee. DT imaging data were obtained from 14 rats after permanent middle cerebral artery occlusion (pMCAO) using a 7T magnetic resonance scanner (Bruker) in room air. Relative cerebral blood flow and apparent diffusion coefficient (ADC) maps were generated to define oligemia, TP, IC, and normal tissue (NT) every 30 minutes up to 3 hours. Relative fractional anisotropy (rFA), pure anisotropy (rq), diffusion magnitude (rL), ADC (rADC), axial diffusivity (rAD), and radial diffusivity (rRD) values were derived by comparison with the contralateral normal brain. Results: The mean volume of oligemia was $24.7{\pm}14.1mm^3$, that of TP was $81.3{\pm}62.6mm^3$, and that of IC was $123.0{\pm}85.2mm^3$ at 30 minutes after pMCAO. rFA showed an initial paradoxical 10% increase in IC and TP, and declined afterward. The rq, rL, rADC, rAD, and rRD showed an initial discrepant decrease in IC (from -24% to -36%) as compared with TP (from -7% to -13%). Significant differences (p < 0.05) in metrics, except rFA, were found between tissue subtypes in the first 2.5 hours. The rq demonstrated the best overall performance in discriminating TP from IC (accuracy = 92.6%, area under curve = 0.93) and the optimal cutoff value was -33.90%. The metric values for oligemia and NT remained similar at all time points. Conclusion: Benign oligemia is small and remains microstructurally normal under pMCAO. TP and IC show a distinct evolution of DT-derived properties within the first 3 hours of stroke onset, and are thus potentially useful in predicting the fate of ischemic brain.

  • 본 연구는 만성요통을 호소하는 여성노인을 대상으로 뜸 요법을 중재 방법으로 적용하여 일상생활기능장애 및 수면 양상을 효율적으로 관리 할 수 있는지 그 효과를 규명하기 위해 시도된 비동등성 대조군 전후 실험연구이다. G시에 거주하는 여성노인(실험군 30명, 대조군 30명)으로 2015년 3월 15일부터 5월 31일까지 뜸 요법을 12주간 주 1회 총 12회 뜸 요법을 적용하였고, 추후조사는 사후조사 2주후에 실시하였다. 뜸 요법은 요혈인 신수(腎諭)와 아시혈, 대장수(大腸兪), 요양관(腰陽關), 요수(腰兪)을 취혈하였다. 무극보양뜸 7혈인 족삼리(足三里) 곡지(谷地), 중완(中脘), 중극(中極)과 수도(水道), 폐수(肺愈), 고황과 천추(天樞), 위중(委中)부위에 각각 5장씩 뜸처치를 실시하였다. 연구도구는 요통정도를 사정하기 위해 Scott & Huskisson(1979)이 개발한 시각적 상사척도(Visual Analog Scale ; VAS)를 사용하였고, 일상생활기능장애 측정 도구는 Fairbank 등(1980)이 개발하고 임현술 등(1998)이 번역 수정한 Oswestry Disability Index를 이용하여 측정하였다. 수면양상 측정 도구는 오진주, 송미순, 김신미(1998)가 개발한 수면 측정 도구를 이용하였다. 자료분석은 SPSS/WIN 18.0을 사용하였으며 Chi-square test, t-test, repeated measures ANOVA를 실시하였다. 대조군에 비해 뜸 요법을 제공받은 여성노인의 통증점수(F=2510.32, p<.001), 일상생활기능장애 점수(F=1937.82, p<.001), 수면양상점수((F=15.54, p<.001)가 유의한 차이로 나타났다. 따라서 뜸요법은 통증과 일상생활기능장에를 감소시키고, 수면의 질을 향상시키는데 긍정적인 기여를 하는 것으로 나타나 향후 뜸요법이 만성요통을 호소하는 노인에게 간호중재로 활용할 필요가 있다.
