Introduction
The health care industry is rich in data and information. Web technologies, such as search engines and social media, have provided an opportunity for the management of user generated data in real time in the form of infodemiology studies. The aim of this study was to investigate infodemiology studies conducted during 2002–2016, and compare them based on developed, developing and in transition countries.Methods
This scoping review was conducted in 2017 with the help of the PRISMA guidelines. PubMed, Scopus, Science Direct, Web of Knowledge, Google Scholar, Wiley and Springer databases were searched between the years 2002 and 2016. Finally, 56 articles were included in the review and analysed.Results
The initial infodemiology studies pertain to the quality assessment of the hospital's websites. Most of the studies were on developed countries, based on flu, and published in the Journal of Medical Internet Research.Conclusion
The infodemiology approach provides unmatched opportunities for the management of health data and information generated by the users. Using this potential will provide unique opportunities for the health information need assessment in real time by health librarians and thereby provide evidence based health information to the people.2.

ABSTRACT As the world is witnessing the epidemic of coronavirus disease 2019, emerging genetics and clinical pieces of evidence suggest a similar immunopathology to those of severe acute respiratory syndrome and Middle East respiratory syndrome. Staying at home to prevent the spread of the virus and consequently being largely inactive is associated with unintended consequences. These can actually enhance the infection risk and exacerbate poor health conditions including impaired immune function. Physical activity is a feasible way of improving health, particularly physical and mental health in a time of social isolation. However, people with certain health conditions in these circumstances may need a special physical activity programme in addition to any exercise they may already be performing via online programmes. This review aims to provide practical guidelines during the COVID-19 quarantine period. We suggest performing aerobic, resistance training, respiratory muscle training and yoga in the healthy, and in those with upper respiratory tract illness, patients with lower respiratory tract illness should be restricted to respiratory muscle training and yoga. In addition, vitamins D and C, omega-3 fatty acids, and regular consumption of fruit and vegetables might be considered as nutritional aids to support the immune system in those affected by COVID-19. 相似文献

In this paper, a method for the design of 2-D analog and recursive digital filters is presented. Starting from a structure in the analog domain, suitable even or odd parts of two-variable Hurwitz polynomials are generated. This enables 2-variable very strictly Hurwitz polynomials (VSHP) to be obtained,2 thus avoiding non-essential singularities of the second kind. Thus it will ensure a stable 2-D recursive digital filter obtained by the use of bilinear transformations. Examples are given to illustrate the method. 相似文献

A short 33-item form of the Career Development Inventory was validated on a sample of 310 Iranian high school students. Factor
analysis indicated that attitude and cognitive subscale items loaded on their respective factors, and that internal reliability
coefficients at all levels were satisfactory to good. Support for validity was demonstrated by associations in the expected
direction for career decidedness and career decision-making self-efficacy. This short form of the inventory shows promise
as a measure of career maturity with students from a non-Western country. 相似文献

Job performance can be defined as the extent to which one exhibits behaviors that further the goals of the organization, and leaders try to manage the factors influencing the performance in an organization to guide it toward organizational goals. A main factor that influences the performance is emotions and behavior of other people. The influence of people on each other can be divided into physical and metaphysical contagions in the scientific literature. In this article, we introduce a new kind of metaphysical contagion that has a close relationship with individual and organizational performance. We name it performance contagion and introduce two kinds of factors (content and process) and subfactors. We conceptualize a new concept in performance management defined as human resource layout. Tools are suggested for applying the steps of this model to improve both individual and organizational performance. 相似文献

Atherosclerosis is a pathologic disorder which has an important role in the occurrence of coronary heart disease. It is determined as a focal, inflammatory proliferative response to several types of endothelial damage. Apolipoprotein B which is a requirement in the sustenance of cholesterol homeostasis, and is the major protein component of low density lipoprotein, characterized by multitude polymorphic sites, one of which (12669G>A) is related to the levels of serum lipid profiles, coronary artery disease and/or myocardial infarction. One Common polymorphism which is more important in this process is 12669G>A that is appraised in this research. We recruited 80 patients from the Mousavi hospital, Zanjan, Iran, diagnosed with coronary artery disease by the clinician on the basis of clinical symptoms, echocardiogram result, and angiography. Seventy-seven healthy individuals without any evident symptoms of Coronary stenosis and any past history of the disease were taken as controls from the general population. We carried out PCR using specific primers. Then, we digested PCR product by RFLP. Lipid parameters by biochemical methods and Apolipoprotein B serum level by immunoturbidometry method were done. Genotype frequencies for 12669G>A polymorphism were determined: 55 % R+R+, 45 % R+R? in case group, and 55.8 R+R+, 44.2 % R+R? in controls. The R?R? genotype was not seen. There was no significant relationship between this polymorphism and the risk of Coronary stenosis (P = 0.6). In the present study, higher plasma levels of cholesterol and low density lipoproteins in the subjects with R+R? genotype were found while there was no association between this polymorphism and coronary stenosis with ≥50 % in the Zanjan population. 相似文献

In this paper, we present an intelligent architecture, called intelligent virtual environment for language learning, with embedded pedagogical agents for improving listening and speaking skills of non-native English language learners. The proposed architecture integrates virtual environments into the Intelligent Computer-Assisted Language Learning. This architecture supports visual, auditory, and haptic channels of interaction. It allows pedagogical ideas about language skills to be implemented and validated with a minimum design time. Moreover, we design a computational model to evaluate learner's proficiency level, and an automatic adaptation mechanism which adjusts to the learner's learning curve. We have implemented two scenarios based on the proposed architecture to teach learners how to communicate in public places such as airports and TV stores. Inputs to this system include learner's speech and hand motion, and outputs include graphical scenes, force feedback, and speech by a few embodied agents. Throughout interactions, agents discover the proficiency level of the learner and customize the level of communication complexity accordingly. The system is tested on 10 subjects. Experimental results show 14% increase in the number of proper replies, 3% decrease in grammatical errors, 16% decrease in pronunciation duration, and 11% increase in learners' proficiency level within three trials. 相似文献

This paper examines three methods to measure the upper arm rotation, the main contributor to produce a fast first serve in
tennis. Accepted videography techniques were compared with a novel inertial gyroscope system and marker-based technique. A
network of two inertial sensors on the upper arm and the chest was used to measure upper arm rotation angle and remove body
artifacts. A marker-based virtual gyroscope (MBVG) was derived from Vicon marker positions in the standard Plug-in-Gait model
using a vector-based method of marker trajectories and a series of geometric transformations. The results indicate that there
is a close temporal feature match for all three methods when applied to the tennis serve. This paper shows that gyroscopes
as well as the MBVG can be advantageous for tennis serve assessment. 相似文献

Cardiovascular disease, as the leading cause of patient death with chronic kidney disease, could be predicted by carotid atherosclerosis. The aim of the present study was to evaluate a possible relationship between serum soluble tumor necrosis factor-like weak inducer of apoptosis (sTWEAK) and Vitamin D levels with mean right/left carotid intima-media thickness (cIMT), in the hemodialysis (HD) patients. In this cross-sectional study, serums were obtained from 50 stable chronic HD patients and 39 healthy controls. The serum levels of sTWEAK, Vitamin D, intact parathyroid hormone (iPTH) in both groups, and cIMT were determined in HD patients by standard methods. Serum levels of sTWEAK were higher [808.8 (521.6–5032.4) pg/ml vs. 664.4 (487.4–2955.8) pg/ml (p = 0.006)] and Vitamin D levels were lower [13.4 (2.5–153) ng/ml vs. 27.8 (18.4–59.0) ng/ml (p = 0.001)] in the hemodialysis patients than in the healthy control. No important correlation was found between sTWEAK Vitamin D levels (r = 0.010/p = 0.946), and mean right(r = ?0.194/p = 0.178) and left (r = 0.061/p = 0.673) cIMT in the HD patients. Our study shows that sTWEAK levels are elevated in HD patients. This elevation has no association with the cIMT. 相似文献
