BACKGROUND Adherence to prescribed therapeutic regimen is an important element of self-care behaviors in cardiac patients. Awareness of disease may play an important role in patient adherence. Thus, this study was conducted to examine the relationship between awareness of the disease and adherence to therapeutic regimen among cardiac patients admitted to selected hospitals in Mashhad, Iran. M...

The aim of this study was to identify the relationship between the knowledge of leadership and knowledge management practices. This research strategy, in terms of quantity, procedure and obtain information, is descriptive and correlational. Statistical population, consist of all employees of a food industry in Kurdistan province of Iran, who were engaged in 2016 and their total number is about ...

Two experiments investigated free sorting, a type of unsupervised learning, with multiattribute drawings of alien animals. In previous research on concept formation, with simpler stimulus structure than ours, participants were insensitive to correlational structure in the stimuli, producing primarily "ID sorts," based on the values ofjust 1 dimension or attribute. Our experiments showed that pa...

Literal acceptance of the results of fitting "causal" models to correlational data can lead to conclusions that are of questionable value. The long-established principles of scientific inference must still be applied. In particular, the possible influence of variables that are not observed must be considered; the well-known difference between correlation and causation is still relevant, even wh...

Snoring detection is important for diagnosing obstructive sleep apnea syndrome (OSAS) and other respiratory sleep disorders. In general, audio signal processing such as snoring sound analysis uses the frequency characteristics of the signal. Recently, a correlational filter Multilayer Perceptron neural network (f-MLP) has been proposed, which has the first hidden layer of correlational filter o...

Correlation clustering is a concept of machine learning. It was introduced in Bansal et al. [2], which gives a good overview of the mathematical background as well. Let G be a complete graph on n vertices and label its edges with + or − depending on whether the endpoints have been deemed to be similar or different. Consider a partition of the vertices. Two edges are in conflict with respect to ...

Background: According to the biopsychosocial model, menstrual symptoms are caused not only by a combination of biological factors such as hormonal disorders and lifestyle, but also by psychological and social factors such as working environment. This study aimed to determine the relation between occupational stress and dysmenorrhea in Iranian midwives. Materials and Methods: This prospective co...
