Abstract

Tea and ascorbic acid have antioxidative and anti-inflammatory effects, and vitamin D and zinc have immunomodulatory effects. This study investigated the effect of a nutraceutical prescription combining these four nutrients on the blood biochemical markers and the modified C19-YRS questionnaires in patients who had recovered from COVID-19 disease for four months. Analysis of six markers associated with long COVID symptoms, i.e., INR, d-dimer, hs-CRP, NT-ProBNP, IL-6 and IgA, indicated that the nutraceutical could positively affect the values, especially for the inflammatory markers. The physician’s clinical observation and questionnaire analysis reported significant improvements in post-exertional malaise, sleep quality and overall health of the patients. These results suggested that formulated nutraceutical could not only reduces or eliminates the symptom of long COVID, but potentially also prevents reinfection.

Abstract

The Dragonfly Algorithm (DA) is a novel swarm intelligence algorithm with some positive applications in recent years. The algorithm simulates the basic survival ability of dragonflies to evade predators and capture prey in natural environment. The original DA algorithm converges too fast, and it is easy to fall into the local optimum, which causes the search to stagnate and the algorithm effect is not ideal. Based on above, a collaborative evolutionary dragonfly algorithm (CDA) with multi-group strategy is proposed in this paper. It uses multi-group strategy and Cauchy mutation to jointly improve the convergence speed and accuracy of the original algorithm. Image segmentation is an essential aspect of computer graphics and image processing. It has become increasingly important. This paper uses threshold technology based on the CDA algorithm to find the optimal index value under different threshold conditions. The experimental results have demonstrated that the CDA is highly competitive in terms of convergence speed and convergence accuracy DA algorithm, and CDA also performs excellent advantages in graphic segmentation experiments. &nbsp

Abstract

Business-to-consumer (B2C) e-commerce has been rapidly changing the competitive landscape of the retailing and service industries. Despite its claimed benefits, this innovative mode of retailing has not yet been accepted by every buyer and seller. An interesting question is why some consumers accept the idea of online shopping more readily than others. At the organizational level, a similar question is why some sellers have stronger intention to develop (B2C) e-commerce than others. This attitudinal and behavioral difference among individuals and organizations in the face of innovation has been widely studied in various disciplines such as innovation adoption, technology acceptance, marketing, and strategic management. The current research consists of two separate yet intellectually correlated empirical studies. Study 1 investigated how potential online consumers' individual characteristics affected their attitude and intention toward online shopping in a sample of 474 students. It was found that cognitive and psychological characteristics more than demographic characteristics were associated with a consumer's online shopping attitude and purchasing intention. Study 2 proposed and tested a multi-level theoretical model about the factors influencing a firm's intention to develop e-commerce. Travel agencies in Taiwan were selected as research subjects. Interviews were conducted with one government official of the Tourism Bureau and ten travel agency CEOs. Survey data were collected from a sample of 137 travel agencies. Positive and statistically significant relationships were found between perceived competitive pressure, market-driving orientation, IT resource base and e-commerce intention. By contrast, customer-led orientation was negatively associated with e-commerce intention. Implications of these findings for academic research and e-commerce practices are also discussed., Wang, Shu-chuan., Adviser: Waiman Cheung., Source: Dissertation Abstracts International, Volume: 62-09, Section: A, page: 3111., Thesis (Ph.D.)--Chinese University of Hong Kong, 2001., Includes bibliographical references (p. 159-195)., Electronic reproduction.

Abstract

Physical activity can both prevent and protect against various conditions and diseases, including obesity, cardiovascular disease, cancer, and non-Insulin-dependent diabetes mellitus. However, it is understudied among aboriginal population in both Taiwan and the U.S. The purposes of this study are 1) to understand the physical activity disparities between aborigines and the general population in Taiwan and those between Native Americans and non-Hispanic Whites; 2) to examine the age effect on racial differences of physical activity; and 3) to explore how social determinants confound the prevalence of physical activity. This study will employ data from the National Health Interview Survey (NHIS) in Taiwan and the U.S. respectively. [ABSTRACT FROM AUTHOR]

31. Native American-White differences in adult health

Author

Wang, Shu-Chuan

Abstract

The goal of this work is to document the health gaps between Native Americans and non-Hispanic Whites using a recent, consistent, and national-level dataset—the National Health Interview Survey. I find that Native Americans have poorer self-reported health and more activity limitations than Whites; Native Americans are more likely to have no doctor visits than Whites; Native Americans spend more days in bed than Whites. Further, Native American-White differences in activity limitations and bed days are completely mediated by socioeconomic factors. SES also accounts for a large portion of the racial gap in self-reported health and physician utilization. The racial gap in self-reported health between Native Americans and Whites narrows with age. However, similar patterns for activity limitations, bed days, and doctor visits are not observed. Although it is found that Native Americans living in metropolitan areas have better self-reported health than Native Americans living in non-metropolitan areas, non-MSA Native Americans are less likely to have an activity limitation and more likely to have no doctor visits than MSA Native Americans. With the exception of doctor visits, the health gaps between Native Americans and Whites in non-MSA areas are narrower than those in MSA areas. When SES or health variables are controlled, all racial gaps in non-MSA areas are narrower than those in MSA areas. With respect to mortality, Native Americans are found to have a higher risk than Whites and the risk of death for Native Americans versus Whites declines with age. Compared to Whites, Native Americans are less likely to drink but they are more likely to drink heavily. Generally, Native Americans are more likely to smoke than Whites; however, they do not necessarily smoke more heavily than Whites, especially after controlling for SES. Native Americans are more likely to be physically inactive compared to non-Hispanic Whites.

Abstract

Background: Peritonitis rate has been reported to be associated with technique failure and overall mortality in previous literatures. However, information on the impact of the timing of the first peritonitis episode on continuous ambulatory peritoneal dialysis (CAPD) patients is sparse. The aim of this research is to study the influence of time to first peritonitis on clinical outcomes, including technique failure, patient mortality and dropout from peritoneal dialysis (PD)., Methods: A retrospective observational cohort study was conducted over 10 years at a single PD unit in Taiwan. A total of 124 patients on CAPD with at least one peritonitis episode comprised the study subjects, which were dichotomized by the median of time to first peritonitis into either early peritonitis patients or late peritonitis patients. Cox proportional hazard model was used to analyze the correlation of the timing of first peritonitis with clinical outcomes., Results: Early peritonitis patients were older, more diabetic and had lower serum levels of creatinine than the late peritonitis patients. Early peritonitis patients were associated with worse technique survival, patient survival and stay on PD than late peritonitis patients, as indicated by Kaplan-Meier analysis (log-rank test, p = 0.04, p < 0.001, p < 0.001, respectively). In the multivariate Cox regression model, early peritonitis was still a significant predictor for technique failure (hazard ratio (HR), 0.54; 95% confidence interval (CI), 0.30 - 0.98), patient mortality (HR, 0.34; 95% CI, 0.13 - 0.92) and dropout from PD (HR, 0.50; 95% CI, 0.30 - 0.82). In continuous analyses, a 1-month increase in the time to the first peritonitis episode was associated with a 2% decreased risk of technique failure (HR, 0.98; 95% CI, 0.97 - 0.99), a 3% decreased risk of patient mortality (HR, 0.97; 95% CI, 0.95 - 0.99), and a 2% decreased risk of dropout from PD (HR, 98%; 95% CI, 0.97 - 0.99). Peritonitis rate was inversely correlated with time to first peritonitis according to the Spearman analysis (r = -0.64, p < 0.001)., Conclusions: Time to first peritonitis is significantly correlated with clinical outcomes of peritonitis patients with early peritonitis patients having poor prognosis. Patients with shorter time to first peritonitis were prone to having a higher peritonitis rate., (Copyright © 2014 International Society for Peritoneal Dialysis.)

Abstract

In the present paper, Sm3+ doped borate glasses (LBLB) with high effective visible fluorescence emission have been synthesized. The absorption and fluorescence spectra of this glass were measured and analyzed. The absorption spectra were fitted by J-O theory, and the intensity parameters omega = (2, 4, 6) were found to be 6.81 x 10(-20), 4.43 x 10(-20), and 2.58 x 10(-20) cm2, respectively, then the relative intensity of spectral lines of every energy level transition, radiative transition probabilities, radiative lifetimes, and fluorescence branching ratio were calculated. Under the excitation of UV light, Sm3+ doped borate glasses (LBLB) emit bright salmon pink light. The excitation spectra indicate that argon laser is an effective excitation source in Sm3+ doped LBLB glasses.
