Abstract Background Most dental procedures are time-taking and also need professional skills to obtain the desired results. To achieve success in the dental profession, one needs to modify the previous working conditions. Objective A comprehensive, systematic review was conducted on the available literature to clarify the advantages of the proprioceptive derivation over the conventional approach. Methods Three major scientific databases were used as search engines like Medline/PubMed and EBSCOhost by following three main criteria. The search criteria were based on the proprioceptive derivation concept used in dentistry and the change in the dental workstation environment for an effective way of performing dentistry. They modified work postures that reduce the risk of work-related musculoskeletal diseases. Results The Proprioceptive derivation approach resulted in improvement in all the three objectives followed in this systematic review. Applying the proprioceptive principles resulted in comfort and work efficiency in performing dental procedures. Conclusion Applying the Pd concept to dental practice reduces work-related musculoskeletal disorders and improves dental clinicians’ work efficiency and longevity.

Abstract The current paper proposes a novel taxonomy of latent hazard anticipation by distinguishing modal, strategic, tactical, and operational hazard anticipation skills. Novice drivers face an increased risk of being involved in fatal motor vehicle crashes. Research involving both on-road and driving simulator studies suggests that novice drivers are especially poor at anticipating latent hazards. We reviewed and synthesized previous works on hazard anticipation in young drivers. Modal hazard anticipation skills are broader in nature and more applicable to the general traffic, roadway, and environmental conditions, while strategic, tactical, and operational hazard anticipation skills are more scenario-specific and necessary when navigating a potentially safety-critical situation. It is known that error-based feedback training programs can improve both tactical and strategic, but not yet operational and modal hazard anticipation abilities of novice drivers. Future research should explore individual differences in the effectiveness of training interventions for young novice drivers.

Abstract Driving distraction is an important cause of traffic crashes, as it diverts the driver’s attention away from the primary driving task. This paper studies the engagement frequency of drivers in distracting activities due to modern devices used in vehicle dashboards, to improve roadway safety. Data were collected from Jordanian drivers through two questionnaires. In the first, a wide range of distracting activities and their influence on crashes were considered. The focus of the second questionnaire was on factors affecting the driver’s distraction by the Human-Machine Interface (HMI) screens in vehicles. The collected data were analyzed statistically. Several significant factors were found that distract drivers, including but not limited to the use of HMI screens, the driver’s age, experience and occupation. This paper raises public awareness of the risks of distracted driving due to modern devices, in order to boost traffic safety.

Abstract Patient satisfaction is an important and frequently used outcome measure for the quality of healthcare services. Any increase in patient satisfaction scores translates directly into an improved reputation, customer loyalty, profitability, and growth. This study investigates the effect of a well-designed work environment on medical laboratory employee satisfaction and in turn on patient satisfaction. The Quality Function Deployment methodology is used to translate the voice of patients into a set of critical to quality ergonomic aspects that are converted to prioritized and actionable ergonomic processes. By understanding the importance of ergonomic process elements of medical laboratory employee satisfaction and their effect on patient satisfaction level, it is possible to make informed decisions about the workplace elements that need to be considered for improvement. The results of this study highlight the role and responsibilities of healthcare execution managers in creating ergonomics-based organizational policies and strategies, leading to improved healthcare quality performance and financial results.

Abstract Due to the limited capacity of the brain, prolonged mental tasks placed on an individual could cause cognitive fatigue (CF). CF is known to cause attention deficits, leading to poor situational awareness and vigilance. Depending on the circumstances, such attention deficits may cause catastrophic outcomes, causing harm to many individuals. Hence, early identification of CF is mandatory. Wearable technology seems to provide a promising solution in detecting CF by monitoring the alterations of physiological parameters, eye movements, speech, or brain activity. Further, some recently developed wearable devices are shown to have the potential to alert the user regarding an impending CF and activate safety measurements. However, other coinciding factors, such as emotions or exercise, could alter the aforementioned factors used in the detection of CF. Thus, the accuracy and validity of recognizing CF using wearables are lower than detecting physical fatigue. However, with the advancements of technology, these devices continue to demonstrate excellent improvements. This article provides a condensed summary of the use of wearable devices in detecting CF in the recent literature and their possible developments in the future. Concepts discussed in the article will interest the ergonomists, health and safety engineers, human factors engineers, and health care professionals.

Abstract We consider a situation, when braking is the only way to avoid obstruction of an automotive vehicle or a railroad train with a suddenly detected steadfast obstacle blocking the path. The velocity at the moment of the impact is viewed as a natural and a suitable criterion of the severity of the impact and, hence, of the very likelihood of the accident. Assuming that this velocity is distributed in accordance with the Rayleigh law, it is shown that the corresponding available sight distance (ASD) treated as a non-random function of the random impact velocity follows the exponential distribution. The variability (uncertainty) of the ASD measurements by the navigation system’s Radar(s) and/or Lidar(s) is assessed assuming that these measurements are normally distributed random variables. It is determined that the accuracy of these measurements, when the actual ASD is short and because of that the expected level of the impact velocity and, hence, the probability of the obstruction, are significant, is as important as the actual, objective, measurement independent ASD. The obtained information can be useful when choosing, developing and employing Radars and/or Lidars as effective navigation devices in various vehicular human-system-integration/interaction (HSI) technologies. This is true not only for the particular automotive or railroad situations in question, but also in other areas of vehicular engineering, such as, say, aerospace (e.g., when landing on Mars or on the Moon) or in maritime engineering (e.g., when encountering an obstacle, like another vessel or an iceberg, or when establishing an adequate under-keel clearance for large tankers navigated in shallow waters).

Abstract The paper highlights the need to determine applicability of various ergonomic assessment methods. The methods such as Ovako working posture analysing system (OWAS), Rapid entire body assessment (REBA) and Rapid upper limb assessment (RULA) were used for the evaluation. The current research is carried out in three phases. The first phase involves assessing 25 postures at four different load levels (100 postures) to confirm the existence of variation in outcome of assessment. In the second phase, 24 male participants were selected to simulate the selected set of 100 postures-load combination in the laboratory and their perceived exertion rating was noted. Phase three includes the result’s validation. ANOVA was carried out to identify significant factors. It may be concluded from the study that OWAS may be better suited to evaluate risk if the load is less than 5 kg. Similarly, REBA and RULA may be better suited for the load range 5 kg − 10 kg and load greater than 10 kg respectively. It is observed that outcome of assessment methods is insensitive to some posture cases. So, there is a need to identify all the insensitive zones within a method that has a considerable difference in perceived exertion.
摘要本文强调了确定各种工效学评估方法适用性的必要性。采用Ovako工作姿势分析系统(OWAS)、快速全身评估(REBA)和快速上肢评估(RULA)等方法进行评价。目前的研究分三个阶段进行。第一阶段包括在四种不同负荷水平(100个姿势)下评估25个姿势，以确认评估结果存在差异。在第二阶段，选择24名男性参与者在实验室模拟选定的100种姿势负荷组合，并记录他们的感知劳累等级。第三阶段包括结果的验证。进行方差分析以确定显著因素。从研究中可以得出结论，如果负荷小于5公斤，OWAS可能更适合于评估风险。同样，REBA和RULA可能更适合负载范围5 kg - 10 kg和负载大于10 kg。观察到评估方法的结果对某些姿势情况不敏感。因此，有必要在一种方法中识别出所有的不敏感区域，这种方法在感知的用力方面有相当大的差异。

Abstract The notion of advanced technology is predominantly portrayed in a positive light and discussed within a dialogue that delivers benefits to its users. The term ‘smart city’ has been used to convey this concept whereby technology can deliver an ‘intelligent effect’. However, many instances of smart city concepts tend to focus on the technology more than the inhabitants who have to co-exist within this solution. This paper discusses these factors by highlighting a smart city project example, Flying High, a project that focussed on the use of unmanned aerial systems within the environs of a city. Use cases were generated via a stakeholder engagement that epitomised the benefits of adopting this technology within the city. Civil security, medical transit and intelligent transport were found to be key uses of smart technology specific to future cities. Key to the findings of these use cases for this technology within the city are discussed in terms of their perceived feasibility, suitability and both economic and social impact. These factors are discussed in relation to the use cases, whilst also highlighting the importance of human socio-technological issues such as governance and the effect of public attitude to the uptake of advanced technology.

Abstract The objective of our study was to investigate differences in cognitive performance connected with physical load of varying intensities. One half of 88 examined persons sat on office chairs, and the other half sat on chairs with the added modification of the gymnastic (Swiss) ball called the dynamic directional seat pad (pad). The first rest phase was followed by the load phase, in which the subjects were administered a 20-minute sustained attention test. The number of correct answers and errors was evaluated. A BIOPAC apparatus continually recorded thoracic respiration, electrodermal activity, finger temperature, heart rate, and heart rate variability. Females on pads made 58% fewer errors than females on chairs; the number of errors was closely related to the depth of their breathing (tidal volume). It was found out that the use of the pad, in addition to the already known health benefits, also brings an increase in the precision of cognitive performance. LIST OF ABBREVIATIONS

Abstract Future thinking (FT) is the cognitive ability that enables humans to mentally imagine and pre-experience future events. Despite a sharp increase in basic research on future thinking in the last decade, we note the lack of transfer to Human Factors and Ergonomics (HF&E), although the field is increasingly concerned by future artefacts and although theory building on future-oriented HF&E has begun (e.g. prospective ergonomics). This article gives an overview of key findings regarding future thinking, namely i) underlying cognitive mechanisms, ii) functions and obstacles, iii) common descriptors of future thinking, iv) recommendations as to the possible improvement of future thinking during user research and, v) methods for the assessment of future thinking abilities. This synthesis can support HF&E practitioners in fine-tuning their future-oriented methods.

This article gives an overview of key findings regarding future thinking, namely i) underlying cognitive mechanisms, ii) functions and obstacles, iii) common descriptors of future thinking, iv) recommendations as to the possible improvement of future thinking during user research and, v) methods for the assessment of future thinking abilities. This synthesis can support HF&E practitioners in fine-tuning their future-oriented methods.","PeriodicalId":22852,"journal":{"name":"Theoretical Issues in Ergonomics Science","volume":"23 1","pages":"347 - 373"},"PeriodicalIF":1.6,"publicationDate":"2021-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/1463922X.2021.1943045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44495110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
