An alternative inference tool to total probability formula and its applications

Total probability and Bayes formula are two basic tools for using prior information in the Bayesian statistics. In this paper we introduce an alternative tool for using prior information. This new toold enables us to improve some traditional results in statistical inference. However, as far as the authors know, there is no work on this subject, except [1]. The results of this paper can be extended to other branches of probability and statistics. In Section 2 total probability formula based on median is defined and its basic properties are proved. A few applications of this new tool are given in Section 3.Comment: Presented at the 23th Int. worskhop on Bayesian and Maximum Entropy methods (MaxEnt23), Aug. 3-7, 2003, Jackson Hole, US

Bayesian segmentation of hyperspectral images

In this paper we consider the problem of joint segmentation of hyperspectral images in the Bayesian framework. The proposed approach is based on a Hidden Markov Modeling (HMM) of the images with common segmentation, or equivalently with common hidden classification label variables which is modeled by a Potts Markov Random Field. We introduce an appropriate Markov Chain Monte Carlo (MCMC) algorithm to implement the method and show some simulation results.Comment: 8 pages, 2 figures, presented at MaxEnt 2004, Inst.

The Opportunities and Damages of Virtual Social Networks from Students\u27 Perspectives; the Experience of Iranian Users

Today, virtual social networks affect different dimensions of individual and social life of individuals and in the future they will play a much greater and more important role in life. The present study aims to study the positive and negative effects of virtual social networks from students\u27 point of view medical and non-medical sciences universities of Gonabad city. This is a descriptive-survey study. The research population of the study population was Gonabad, a university student in the academic year of 2016-2017. To determine the sample size, 350 samples were selected using Cochran formula and selected by stratified random sampling from the research community. The data gathering tool in this study was a demographic questionnaire and a researcher-made questionnaire that was a measure of the effects of virtual social networks. The collected data were analyzed using SPSS version 20 software. networks social telegram with 96% and Instagram 60.9% were the most popular. communication with friends and acquaintances with an average of 16 and education with an average of 11, the most significant positive effects and anti-religious propaganda with an average of 17, and rapid formation and promotion The rumors with the average of 13 are the most negative effects of using these networks. There was also no significant difference between the viewpoints of students of medical and non-medical sciences universities in Gonabad. Facilitating virtual communication and education from the viewpoint of students is the most important opportunity to use virtual social networks. Also, anti-religious propaganda and the instigation of doubts, the formation and promotion of rumors are also a threat to such networks

THE EFFECT OF GASTRIC GAS EMPTYING ON THE RESIDUAL GASTRIC VOLUME IN MECHANICALLY-VENTILATED INTENSIVE CARE UNIT PATIENTS FED THROUGH NASOGASTRIC TUBES: A RANDOMIZED, SINGLE-BLIND, CLINICAL TRIAL

Objective: Increased gastric residual volume is a complication of enteral nutrition intolerance that leads to gastrointestinal complications such as nausea, vomiting, and aspiration pneumonia. The present study was conducted to determine the effect of gastric gas emptying on the residual gastric volume in mechanically-ventilated patients fed through nasogastric tubes.Methods: This randomized, single-blind, clinical trial was conducted on two groups of patients in the intensive care unit (ICU) of Kamyab Hospital of Mashhad. A total of 64 patients were randomly divided into a case and a control group. In the case group, the gastric gases accumulated through the nasogastric tube were emptied by applying palm pressure on the epigastric region. The control group did not undergo this intervention but received the routine care provided in the ward. Data were collected using a demographic questionnaire and a form containing records of the patients' residual gastric volume and disease-related information. The residual gastric volume was measured and compared in the two groups before and after the intervention. Data were analyzed in SPSS-19 using the Chi-square test, the independent t-test, and the repeated measures ANOVA at the significance level of 5%.Results: The residual gastric volume did not differ significantly between the two groups before the intervention (p=0.14); after the intervention; however, a significant reduction was observed in the case group compared to the controls (p=0.007).Conclusion: Gastric gas emptying helps reduce the residual gastric volume in mechanically-ventilated patients fed through nasogastric tubes. Further studies are recommended to further ensure the benefits of this method

National Health Information Network: Lessons Learned From the USA and the UK

National Health Information Network (NHIN) is a network in which all health care organizations, government agencies and other health-related organizations are connected to each other to exchange information about health. Due to the necessity of a framework for NHIN development, in this paper, according to the literature review, a definition for NHIN framework was provided, and then the NHIN related projects were reviewed in the United States of America (USA) and the United Kingdom (UK), NHIN and National Programme for Information Technology in the NHS (NPfIT), respectively. The Review of NHIN framework in the countries studied show some similarities and differences in each dimension that are discussed in this framework. NHIN guiding principles in the NHS NPfIT were not regarded or were considered incomplete, compared to the US. NHIN architecture in the US is decentralized while it is centralized in the UK. Based on the review of NHIN framework, these two countries represent important points that can be used in many other countries. However, it can be said that the development of NHIN does not only mean the implementation of national system or systems, or the binding of local health information systems, but It also needs to build on a framework in which many of the issues related to the formation of NHIN would be considered; including the cooperation between government, private sector and stakeholders with regard to local, national and international needs

Evaluation of the Effects of Diabetes Self-Management Education based on 5A Model on the Quality of Life and Blood Glucose of Women with Gestational Diabetes Mellitus

Abstract Introduction: Gestational diabetes mellitus (GDM) is an important condition during pregnancy. The aim of the current study was to evaluate the effects of self-management education based on 5A model on the quality of life and blood glucose level of women with GDM. Methods: This quasi-experimental study was conducted on 54 pregnant women who referred to the urban health care centers affiliated to the Gonabad University of Medical Sciences from March 2019 to March 2020 based on purposive sampling method. Participants were randomly allocated into intervention and control groups based on stratified random sampling using permuted block randomization method. The intervention group received self-management education program based on 5A model in five sessions during two months. Demographic data, blood glucose level, and diabetes quality of life (DQOL) questionnaire were recorded for each participant. Data analysis was performed using the SPSS software version 16 and the level of statistical significance was set at 0.05. Results: Mean age of the participants was 33.11 ± 5.35 years old. At the end of the intervention, the mean blood glucose level of the participants in the intervention group was significantly lower compared to the control group (p<0.001). The quality of life in the intervention group was significantly improved at the end of the intervention compared to the control group (p<0.001). Conclusions: Self-management education based on 5A model can effectively improve quality of life and blood glucose levels in women with GDM
