Visual Saliency Models

Saliency is the quality of an object that makes it stands out from neighbouring items and grabs viewer attention. Regarding image processing, it refers to the pixel or group of pixels that stand out in an image or a video clip and capture the attention of the viewer. Our eye movements are usually guided by saliency while inspecting a scene. Rapid detection of emotive stimuli an ability possessed by humans. Visual objects in a scene are also emotionally salient. As different images and clips can elicit different emotional responses in a viewer such as happiness or sadness, there is a need to measure these emotions along with visual saliency. This study was conducted to determine whether the existing available visual saliency models can also measure emotional saliency. A classical Graph-Based Visual Saliency (GBVS) model is used in the study. Results show that there is low saliency or salient features in sad movies with at least a significant difference of 0.05 between happy and sad videos as well as a large mean difference of 76.57 and 57.0, hence making these videos less emotionally salient. However, overall visual content does not capture emotional salience. The applied Graph-Based Visual Saliency model notably identified happy emotions but could not analyze sad emotions.

Nurses And Physicians

PurposeA physician–nurse relationship is a complex, professional and shared-decision-making process, which is an important predictor of high-quality patient care. The purpose of this paper is to explore the attitude of the physician–nurse relationship in Southern Lebanon hospitals.Design/methodology/approachA descriptive institutional cross-sectional study was conducted among different departments of three hospitals in Southern Lebanon using a validated Jefferson Scale of Attitude.FindingsIn sum, 89 physicians and 245 nurses accepted to participate. The nurses’ mean age was 32 and the physicians’ was 44. The mean score was found to be 46 for all participants, with significantly higher scores noted among nurses compared to physicians (48 vs 43, respectively) and higher scores among females compared to males (48 vs 46, respectively). However, the study scored no significant difference in relation to the degrees attained by nurses and the participants’ years of experience. The majority had agreed that the shortage in the nurses’ staff affects proper patient care delivery. One fourth of the physicians disagreed that nurses should be considered as a collaborator and colleague. Therefore, more work is required to improve this collaboration.Research limitations/implicationsThere is a complex relationship normally displayed by physicians and nurses, which cannot be easily interpreted and analyzed. Physicians and nurses may have given socially desirable responses while filling the questionnaire. Even more, this study was conducted in Hospitals in Southern Lebanon, and it would be nice to extend this study to include further hospitals in other regions in Lebanon as well.Practical implicationsNurses had higher scores toward collaboration, with females scoring higher than males. However, overall scores are considered to be lower compared to other countries. Thus, more efforts should be done on improving this communication among nurses and physicians, through promoting inter-professional undergraduate and postgraduate education training toward more effective communication.Social implicationsQuality of patient care would be improved if more work is done on improving the collaboration between physicians and nurses, and this was shown to be required as per study results.Originality/valueThere is a gap in literature assessing this important topic which is the collaboration and attitude of nurses and physicians toward their relationship in Lebanon. It is extremely important that efforts should be taken in order to determine the type of nurse–physician relationship in every local context as this relationship affects quality of patients’ care.

IntroductionChronic cough in childhood is common and causes much parental anxiety. Eliciting a diagnosis can be difficult as it is a non-specific symptom indicating airways inflammation and this may be due to a variety of aetiologies. A key part of assessment is obtaining an accurate cough history. It has previously been shown that parental reporting of ‘wheeze’ is frequently inaccurate. This study aimed to determine whether parental reporting of the quality of a child’s cough is likely to be accurate.MethodsParents of 48 ‘new’ patients presenting to a respiratory clinic with chronic cough were asked to describe the nature of their child’s cough. They were then shown video clips of different types of cough using age-appropriate examples, and their initial report was compared with the types of cough chosen from the video.ResultsIn a quarter of cases, the parents chose a video clip of a ‘dry’ or ‘wet’ cough having given the opposite description. In a further 20% parents chose examples of both ‘dry’ and ‘wet’ coughs despite having used only one descriptor.DiscussionWhile the characteristics of a child’s cough carry important information that may be helpful in reaching a diagnosis, clinicians should interpret parental reporting of the nature of a child’s cough with some caution in that one person’s ‘dry’ cough may very well be another person’s ‘wet’ cough.

Objects classification is one of the most significant problems in computer vision. For improving the accuracy of objects classification, we put forward a new classification method enlightened the whole process that human distinguish different types of objects. Our method mixed visual saliency model and CNN, is more close to human and has apparently biological advantages. Firstly, we built an eye-tracking database to learn people visual behaviors when they classify various objects and recorded the eye-tracking data. Secondly, this database is used to train a learning-based visual attention model, which is based on low-level (e.g., orientation, color, intensity, etc.) and high-level (e.g., faces, people, cars, etc.) image features to analyze and predict the human's classification RoIs. Finally, we established a CNN framework to classify RoIs. The results of the experiment showed our attention model can determine saliency regions and predict human's classification RoIs more precisely and our classification method improved the efficiency of classification markedly.

IntroductionThe aim of this study was to perform a comparative and economic analysis of the degree of development of anxiety-depressive disorder in patients with different types of extrasystolic arrhythmia using different assessment scales.Material and methodsThe study was conducted in 2018–2019 at the premises of clinic No. 4, involving 450 patients (Moscow, Russia). Patients were divided into three groups: with coronary heart disease (CHD) (147 patients), with myocardiodystrophy (MCD) (113) and with cardiopsychoneurosis (CPN) (190). Everyone underwent round-the-clock electrocardiography (ECG) and echocardiography. If symptoms of depressive disorder are detected in a timely manner, the risk of adverse cardiovascular diseases may be reduced.ResultsDepression and anxiety indicators on all three scales differed significantly (p ≤ 0.05) in patients with supraventricular extrasystole (more than 40 points on the Zung scale, 14 points on the Montgomery-Asberg depression scale, more than 38 points on Zung and 3 points on Covi anxiety scales). For patients with ventricular extrasystole, a significant difference was established between groups 1 and 2 only in terms of the level of depression on the Zung scale. Factors of psychogenic origin determine the development of cardiac rhythm disturbances.ConclusionsThe study showed that for supraventricular extrasystoles, these factors determine the overall health of the patient. The differences between the three groups are significant on all scales of depression and anxiety (p ≤ 0.05). The most susceptible to depression and anxiety are patients with extrasystolic arrhythmias diagnosed with CHD, as well as MCD.

The aim of the work was establishment of research green roofs on Mendel University in Brno. The experimental green roofs were established in August 2015 and it is based on current issues of rainwater management and the quality of storm water launched into recipients or sewage system. There is a valid legislation addressing the management of rainwater in environment – decree no. 268/2009, Coll., and decree no. 269/2009, Coll. Four experimental plots were created and placed in Mendel University Campus. It was hypothesized that different types of experimental plots will result in different amount of retained water and in different quality of water runoff. Resulting hypotheses proved statistically significant difference between the height of rainfall and runoff height on individual types of green roofs. In addition, it was shown that the different types of roofs prove statistically significant difference in the ability to reduce runoff (retention efficiency).

Often we are faced with the need for thermal treatment of honey. Traditionally this is done by heating the honey. This process requires certain time consumption. Thermal treatment can be greatly accelerated by the use of microwaves. Indicators for thermal treatment and storage of honey traditionally are hydroxymethylfurfural (HMF) content and activity of enzymes. HMF is organic compound, which is created when carbohydrates are dehydrated. HMF content increases when honey is stored for long time or is thermally treated. Our objective of the study was to find out how the different types of honey heat treatment affect the honey enzyme, invertase, activity and HMF content. HMF content in honey was determined using high pressure liquid chromatography. Invertase activity is determined by spectrophotometry. The study results proved that using microwaves to thermally treat honey significantly impacts honey invertase activity and HMF content increases. Invertase activity reduction is more severe compared to the HMF content increase. Thermally treating honey with microwaves, even treating it only 10 seconds, affects the quality of honey.
