An Approach for Designing of Domain Models in Smart Health Informatics Systems Considering Their Cognitive Characteristics
Published in Abdel-Badeeh M. Salem, Innovative Smart Healthcare and Bio-Medical Systems, 2020
Olena Chebanyuk, Olexandr Palahin
To design quality model in Smart Health Information System, it is necessary to spend some efforts to design well-structured model. Requirements for the stable and well-designed models are the following: Consider peculiarities of human perception.Full and strict representation of the system.Possibility to analyze the whole system as well as to investigate detailed algorithms or structure of some system components.Representation of system functionality or structure in full and noncontradictory way.Metamodeling notation for representation of metamodels must provide compact and detailed representation of metamodels in order to design quality models that would satisfy metamodeling notation as well as all stakeholders’ needs.
Governance of patient safety

Subsequently, the shift of emphasis from individuals to systems was pursued extensively to better engage the relation between human reliability and complex systems.65 In particular, the impact of human factors in crisis management received considerable attention.66 This focus on systems led to a keen focus upon the role of human factors, such as in using medical devices,67 including the psychology of human cognition and action and the processes of human perception.68 Not surprisingly, the increased interest in a systems approach to patient safety generated concerns among clinicians and health managers, such as regarding professional liability,69 disclosure and apologies,70 no-fault reporting.71 Yet, the focus on a systems approach to patient safety has increased significantly in healthcare.72
Social connectedness, social interaction and the design of interior environments
Published in Ann Petermans, Rebecca Cain, Design for Wellbeing, 2019
Perceptions of space and the surrounding interior environment are intrinsically tied to human perception and action, as each person has their personal meanings and social interactions within environments. Aesthetic choices are thus grounded in the voices of the various people who are part of the construction of spaces (Vaikla-Poldma, 2013, p. 105). This is amplified when a person ages, as their world diminishes in size and scope. These issues become complex when other people contribute to this world, an increasingly institutional world for people who are elderly, for example. The constructions of these interior environments are many and include users, stakeholders, designers, architects and participants. For those who design spaces ‘understanding intersubjective experiences requires understanding how spaces act on our perceptions and perpetuate social relations’ (Vaikla-Poldma, 2013, p. 105). This means accounting for the meanings people hold in the things that they find pleasurable and how activities provide opportunities for social connectedness and generate feelings of comfort, contentment and wellbeing; and then considering how best to communicate these needs with all stakeholders concerned when designing public places and institutions in particular.
Bibliometric and systemic review of the state of the art of occupational risk management in the construction industry
Published in International Journal of Occupational Safety and Ergonomics, 2023

The use of utility theory and the expected value and variance to evaluate hazardous activities, substances and technologies in industrial environments that involve risks at work have not yielded satisfactory results [32]. This has led researchers to seek methodological procedures based on psychometry so they can better represent and measure the risk perception of workers and understand the consequences of working in potentially unsafe environments. Psychometry is one of the oldest research traditions in psychology [33]. The psychophysical is a scaling and multivariate analysis technique used to produce quantitative representations or ‘cognitive maps’ of risk attitudes. Human perception has been studied for over 100 years, mainly in the areas of medicine and psychology, and more recently in areas like decision-aiding [33].
Research on effective recognition of alarm signals in a human–machine system based on cognitive neural experiments
Published in International Journal of Occupational Safety and Ergonomics, 2023
Yun Teng, Yuwei Sun, Xinlin Chen, Mei Zhang
The main purpose of the design of the alarm signal in the human–machine system is to prompt people to make rapid response and avoid the occurrence of accidents when there is an emergency and dangerous situation in the workplace [10]. The Lawrence accident model shows that in the production process, when danger occurs, the safety monitoring facility sends out an alarm signal, and the perpetrator’s mistakes in accepting, identifying or responding to warnings may lead to accidents [11]. Alarm signals are generally classified into visual and auditory signals. Usually in noisy workplaces, visual signals are more important than auditory signals for the warning function of personnel [12]. Visual alarm signals have been widely used in aircraft, vehicles, navigation, railway transportation and instrument dashboards to instruct operators to pay attention to certain unsafe factors, such as warning that a machine or component is malfunctioning [13–15]. The visual alarm signal is often affected by the visual environment, and its shape, color, size and setting method affect the human visual recognition effect. Therefore, revealing the mechanism of human perception and response to visual alarm signals is very important for the design of appropriate alarm signals.
The Impact of Pitch on Tempo-Spatial Accuracy and Precision in Intercepting a Virtually Moving Ball
Published in Journal of Motor Behavior, 2022
J. Walter Tolentino-Castro, Anna Schroeger, Rouwen Cañal-Bruland, Markus Raab
It is undisputed that auditory stimuli play an important role in human perception (Altieri et al., 2015; Licklider, 1951), but empirical evidence for interception tasks is limited, as auditory information in catching or batting movements are not often studied (but see O’Brien et al., 2020; Sors et al., 2017). A few studies suggest that interception performance deteriorates when auditory stimuli are removed (e.g., Takeuchi, 1993). Further, the importance of auditory information in tasks involving anticipation of moving stimuli (e.g., the landing location of a tennis ball) has also been supported by empirical evidence (Cañal-Bruland et al., 2018; Müller et al., 2019). However, it remains to be determined how changes in sound alter (motor) interception performance (Rinaldi et al., 2016). A systematic manipulation of auditory information in interception tasks would illuminate if temporal and spatial perceptions are sensitive to change in acoustic information (Loeffler et al., 2018). We predict that manipulating sound sources will have a greater impact on temporal errors than spatial errors, as has been shown in temporal underestimations of perceptual time-to-arrival judgments (Gordon et al., 2013).
