Multipoint Fuzzy Prediction for Load Forecasting in Green Buildings
Hsuan-Hao Chang,Wei-Yu Chiu,Ting-Yen Hsieh 제어로봇시스템학회 2016 제어로봇시스템학회 국제학술대회 논문집 Vol.2016 No.10
A novel load forecasting mechanism that uses fuzzy logic and big data, termed multipoint fuzzy prediction (MPFP), is proposed. The prediction mechanism is based on historical data and, therefore, is adaptive to dynamic changes over time when the database is updated properly. The MPFP can be combined with green buildings and renewable energy sources to reduce peak loads and energy consumption. An energy management system (EMS) can be integrated into the framework to achieve an improved level of performance. On the basis of a prediction of load curves, the EMS can discharge energy storage devices when electricity prices are high and charge them when electricity prices are low, reducing costs. Real power demand data were employed to illustrate the validity of the proposed MPFP scheme.

Background: It is reported that the percentage of smudge cells in the blood smear could be a prognostic indicator in chronic lymphocytic leukemia. However, the clinical significance of smudge cells in other hematological malignancies, solid tumors or non-malignant diseases is less clear. Hence, this study was conducted to survey the clinical significance of smudge cells in hematological cancers and other disorders. Materials and Methods: From January to November, 2015, the clinical data of patients who received blood examination with differential counts for clinical purpose and were found to have smudge cells in the peripheral blood film in Far Eastern Memorial Hospital were selected. The percentage of smudge cells and patient outcomes were evaluated for further univariate and survival analyses. Results: A total of 102 patients with smudge cells in their blood smears were included. Smudge cells were frequently presented in out-of-hospital cardiac arrest (OHCA; n=30), infections (n=23), hematological cancers (n=23) and solid cancers (n=10). There was no relationship between the percentage of smudge cells and the patient mortality in all diseases (OR: 1.08, 95% CI: 0.47-2.48, P=1.000) as well as the OHCA group (OR: 1.91, 95% CI: 0.38-9.60, P=0.694). It was observed that in patients with all cancers with the percentage of smudge cells less than 50% had a lower mortality rate in comparison with those who had the percentage of smudge cells of 50% or more (OR: 22.29, 95% CI: 2.38-208.80, P<0.001). Additionally, it was seemingly that patients with smudge cells of 50% or more had a lower survival rate than those with smudge cells less than 50% in all cancers with follow-up at 2-month intervals, but without statistical significance (P=0.064). Conclusions: Our survey indicated that in all cancers, those who had higher percentage of smudge cells were prone to have poor outcomes when compared with the subjects with lower percentage of smudge cells. This finding was quite different from the results of previous studies in which the race-ethnicity of most study populations was non-Asian; hence, further investigations are required. Besides, there was no apparent association of the percentage of smudge cells with patient outcomes in all diseases, including OHCA.

Yen, Ching-Ho,Chang, Chia-Hao,Aslam, Muhammad,Jun, Chi-Hyuck Informa UK (TaylorFrancis) 2018 Communications in Statistics Vol.47 No.6
<P>In this research, multiple dependent state and repetitive group sampling are used to design a variable sampling plan based on one-sided process capability indices, which consider the quality of the current lot as well as the quality of the preceding lots. The sample size and critical values of the proposed plan are determined by minimizing the average sample number while satisfying the producer's risk and consumer's risk at corresponding quality levels. In addition, comparisons are made with the existing sampling plans [Pearn and Wu (2006a), Yen etal. (2015)] in terms of average sample number and operating characteristic curve. Finally, an example is provided to illustrate the proposed plan.</P>

Background/Aims: Incidences of inflammatory bowel disease (IBD), ulcerative colitis (UC), and Crohn’s disease (CD), havebeen increasing in Asia. In this study, we report the relevant clinical characteristics and determined the epidemiological trend ofIBD in Taiwan from 2001 to 2015. Methods: A retrospective study was conducted to analyze data recorded from January 2001through December 2015 in the registered database compiled by the National Health Insurance and provided by the Ministry ofHealth and Welfare, Taiwan. Results: A total of 3,806 patients with catastrophic IBD illness were registered from 2001 to 2015 inTaiwan (CD, 919; UC, 2,887). The crude incidence of CD increased from 0.17/100,000 in 2001 to 0.47/100,000 in 2015, whereasthat of UC increased from 0.54/100,000 in 2001 to 0.95/100,000 in 2015. The prevalence of CD increased from 0.6/100,000 in2001 to 3.9/100,000 in 2015, whereas that of UC increased from 2.1/100,000 in 2001 to 12.8/100,000 in 2015. The male-to-femaleratio in the study sample was 2.19 for CD and 1.62 for UC. The median age of those registered with CD was lower than that ofthose registered for UC: 38.86 and 44.86 years, respectively. A significantly greater increase in CD incidence rate was identifiedamong 20 to 39-year-old compared with other age groups. Conclusions: Using Taiwan’s nationwide insurance database, we determinedthat the number of patients with CD increased more rapidly during the study period than the number of patients withUC, especially among age 20 to 39-year-old, resulting in a decreased UC-to-CD ratio.

( Hung-hsu Yen ),( Chun-hao Chang ) 세계문화관광학회 2014 International Journal of Culture and tourism Resea Vol.7 No.1
Cultural tourism is one of the most popular types of tourism nowadays; however, the mass tourism travel behavior can easily be seen in many cultural attractions. The main purposes of this study were to explore: 1) What are the tourists’ motivations while traveling in Anping area. 2) Would the tourists’ behavior in Anping area act with in-depth and learning behavior. 3) Exploring tourists’ perception differences in Anping area. 4) Exploring different tourists’behavior within different cultural involvement groups. This study applied the convenience sampling to collect 295 valid questionnaires. The results showed: 1) Tourists’ motivations in Anping area tended to like mass tourism motivations. 2) Most tourists’ information searching, visiting, and consuming behaviors in Anping area acted like mass tourism travel type. 3) Anping area’s main cultural concept could not be properly delivered to the tourists. 4) Information searching, tourist guide, and cultural related products consuming were less used by high involvement cultural tourists. This study suggested the government should enhance the cultural elements, the historic story, the design of cultural related products and the planning of whole environment. Moreover, the improvement of self-guide system, the training of commentator, and the promotion of the usage of guiding system were still need to be done. Finally, this study suggested the Tourism Bureau should develop a guiding book to encourage and guide the tourists how to enjoy/explore the true culture of each attractions. Moreover, the proper behavior and perception in cultural attractions should also be educated in future education system or promotion activities. To let tourists know the proper perception, behavior, manner and rules in cultural tourism will enhance the future development of cultural tourism in Taiwan.Keywords:Tourism Motivation, Tourism Behavior, Cultural Tourism Perception.
The Effect of CdS QDs Structure on the InGaP/GaAs/Ge Triple Junction Solar Cell Efficiency
Chen-Chen Chung,Binh Tinh Tran,Hau-Vei Han,Yen-Teng Ho,Hung-Wei Yu,Kung-Liang Lin,Hong-Quan Nguyen,Peichen Yu,Hao-Chung Kuo,Edward Yi Chang 대한금속·재료학회 2014 ELECTRONIC MATERIALS LETTERS Vol.10 No.2
This work describes optical and electrical characteristics of InGaP/GaAs/Ge triple-junction (T-J) solar cells with CdS quantum dots (QDs) fabricated by a novel chemical solution. With the anti-reflective feature at long wavelength and down-conversion at UV regime, the CdS quantum dot effectively enhance the overall power conversion efficiency more than that of a traditional GaAs-based device. Experimental results indicate that CdS quantum dot can enhance the short-circuit current by 0.33 mA/cm2, which is observed for the triple-junction solar cells with CdS QDs of about 3.5 nm in diameter. Moreover, the solar cell conversion efficiency is improved from 28.3% to 29.0% under one-sun AM 1.5 global illumination I-V measurement.
Ionized Gas Outflows in Infrared-bright Dust-obscured Galaxies Selected with<i>WISE</i>and SDSS
Toba, Yoshiki,Bae, Hyun-Jin,Nagao, Tohru,Woo, Jong-Hak,Wang, Wei-Hao,Wagner, Alexander Y.,Sun, Ai-Lei,Chang, Yu-Yen American Astronomical Society 2017 The Astrophysical journal Vol.850 No.2
<P>We present the ionized gas properties of infrared (IR)-bright dust-obscured galaxies (DOGs) that show an extreme optical/IR color, (i - [22])(AB) > 7.0, selected with the Sloan Digital Sky Survey (SDSS) and Wide-field Infrared Survey Explorer (WISE). For 36 IR-bright DOGs that show [O III]lambda 5007 emission in the SDSS spectra, we performed a detailed spectral analysis to investigate their ionized gas properties. In particular, we measured the velocity offset (the velocity with respect to the systemic velocity measured from the stellar absorption lines) and the velocity dispersion of the [O III] line. We found that the derived velocity offset and dispersion of most IR-bright DOGs are larger than those of Seyfert 2 galaxies (Sy2s) at z < 0.3, meaning that the IR-bright DOGs show relatively strong outflows compared to Sy2s. This can be explained by the difference in IR luminosity contributed from active galactic nuclei, LIR (AGN), because we found that (i) L(IR ()AGN) correlates with the velocity offset and dispersion of [O III] and (ii) our IR-bright DOG sample has larger L-IR (AGN) than Sy2s. Nevertheless, the fact that about 75% IR-bright DOGs have a large (> 300 km s(-1)) velocity dispersion, which is a larger fraction compared to other AGN populations, suggests that IR-bright DOGs are good laboratories to investigate AGN feedback. The velocity offset and dispersion of [O III] and [Ne III]lambda 3869 are larger than those of [O II]lambda 3727, which indicates that the highly ionized gas tends to show stronger outflows.</P>
Eosinophilia in Pleural Effusions: a Speculative Negative Predictor for Malignancy
Chu, Fang-Yeh,Liou, Ching-Biau,Sun, Jen-Tang,Bei, Chia-Hao,Liou, Tse-Hsuan,Tan, N-Chi,Yu, Yun-Chieh,Chang, Chih-Chun,Yen, Tzung-Hai,Su, Ming-Jang Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.3
Background: Eosinophilic pleural effusion (EPE) is an eosinophil count more than 10% on cytology of pleural samples. Recently, it was reported that malignancy had been the most prevalent cause inducing EPE. Therefore, we conducted an analysis on the prevalence and etiology of EPE and investigated the relationship between EPE and malignancy. Materials and Methods: Data for pleural cell differential count from patients receiving thoracentesis during the period from January 2008 to December 2013 were compared with clinical data and established diagnosis of patients obtained via electronic chart review. Results: A total of 6,801 requests of pleural cytology from 3,942 patients with pleural effusion who had received thoracentesis were available at Far Eastern Memorial Hospital from 2008 to 2013, and of these subjects, 115 (2.9%) were found to have EPE. The most frequent cause of EPE was malignancy (33.0%, n=38), followed by parapneumonic effusions (27.8%, n=32), tuberculosis pleuritis (13.9%, n=16), transudate effusions (12.2%, n=14) and the presence of blood or air in pleural space (10.4%, n=12). Additionally, an inverse relationship of eosinophilia in pleural fluid was identified in patients with malignancy and EPE. The cut-off eosinophil count in pleural fluid was 15% for the most accurate discrimination between malignancy and benign disorders in patients with EPE. At the cut-off level, the sensitivity and specificity were 65.8% and 67.5%, respectively. Conclusions: Pleural fluid eosinophilia was a speculative negative predictor for malignancy, despite the fact that cancers, including lung cancers and metastatic cancers to lung, were the most leading cause of pleural fluid eosinophilia. An inverse correlation was observed between the pleural eosinophil percentage and the likelihood of malignancy in patients with EPE.
