An empirical regression model toward optimized ergonomic conditions for monitoring room operators using RSM

Purpose This study aims to provide an ergonomic design of the monitoring room that has resulted in safe, functional and comfortable environment for the operators, which may lead to improve the efficiency. Currently, uses of closed‐circuit televisions to monitor the critical environments are widely applicable. The information is continuously transferred and analyzed through a center called monitoring room. Design/methodology/approach Here, through creating a systematic analysis, a series of experiments was performed initially to evaluate and then optimize the parameters such as illumination, visual angle, operator-screen distance, number of scenes display in a single screen, workstation height, screen dimension and monitoring time that may affect the visual skill of the operators. Taguchi orthogonal array was used to analyze the significance of parameters on operator’s response time to a threat. The five parameters were distinguished as significant. Later response surface methodology was utilized to optimize the parameters. Findings Quadratic empirical model developed for the response time exposes the optimum response time was achievable at illumination of 500 lux, visual angle of 13°, operator-screen distance of 60 cm, three scenes, workstation height of 120 cm, screen dimension of 34” and monitoring time of 15 min. This shortened the response time by 28 per cent. The adequacy of the fitted model was successfully verified using the confirmation test with α = 95 per cent. Originality/value The novelty of this work lies in the application of a systematic statistical analysis, which enables considering the interaction among the noise parameters and controllable one simultaneously. Furthermore, the obtained regression model can widely be used for adjusting the parameters accordingly based on various anthropometric data.

Finding the “Eye” Amid a Pandemic Storm: A Holistic Guide Toward Visual and Autonomic Balance

In March, 2020, the world was confronted with the COVID-19 pandemic and worldwide governmental orders to “shelter in place.” Within days of this externally imposed hardship, threatening plans for gathering in every community, behavioral optometry organized a platform for virtual education which united the vision therapy community in mutual self-education, shared over 55 countries around the globe. The following article is distilled from a 4-part series of lectures presented by the author, Dr. Samantha Slotnick, on “Making Remote Vision Therapy Valuable.” These lectures constitute a guide for acting in a supportive capacity for our patients, with attention to the reciprocal roles of a balanced, open and available visual process, and a balanced autonomic nervous system. It addresses the impact of the sympathetic response on the visual system, and offers guidance to help patients selfmodulate the state of their nervous systems, with both bottom-up and top-down direction. In particular it elucidates the role of the peripheral visual field in both stress modulation and binocular visual skill development. It offers recommendations on conducting optometric assessments through the telehealth interface, as well as providing vision therapy through a video-based portal. Through the hardship the pandemic has created, and the wonder of technology, this isolating experience may in fact serve as an opportunity to hone our single most valuable tool in our practice: Ourselves, and our ability to facilitate change for others.

Grouping Multiple Intelligences of Biology Students Using Howard Gardner's MI Model and Testing Its Correlation With Their Parents Job

Multiple intelligences was developed by Howard Gardner’s who focused their study in developmental learningof people. He had make a group contain 8 or 9 aspect, they are linguistic skill, music skill, logic-mathematic skill, spatial-visual skill, bodily-kinesthetic skill, intrapersonal skill, interpersonal skill, naturalis skill dan existency skill. Last two aspect just added. Based on learning theory, these skills that students has, are influented by their own family. In this research, only 7 aspects that was groupped and its tested to find a correlation between multiple intelligences and the family. The “family” in this case mean what kind of mother’s job. These research samples are 44 students from Biology Department, Mathematic and NaturalScience Faculty, Universitas Negeri Padang. Sampling method was purposive sampling. Data was collected by using questionaire. There are no repetition in data collection process. The result shows that parent’s jobdoes not make significant effect to influent student intelligences. This conclusion was made by using Spearman Correlation Formula.

Does visual perceptual testing correlate with caregiver and teacher reported functional visual skill difficulties in school-aged children?

Purpose As occupational therapists embrace evidence-informed and occupation-centred practice, the use of standardised visual perceptual tests remains a strong feature of typical paediatric practice. Yet, the research evidence for the use of such tools is inconclusive at best. This study compared the results of the Test of Visual Perceptual Skills (TVPS) with a checklist of reported functional difficulties in 30 children attending occupational therapy. The purpose of this paper was to determine the usefulness of visual perceptual testing in relation to occupation-centred practice. Design/methodology/approach A descriptive correlational study design was used. Participants were 30 primary school-age children who were on a paediatric occupational therapy caseload. An additional 30 typically developing children participated in the development of the checklist. Findings Correlations were found between reported functional visual skill difficulties and two subtests of the TVPS (visual memory and visual discrimination). No correlation was found between the reported functional difficulties and any of the other five subtests of the TVPS or the total score. Originality/value Results highlight the weak relationship that existed in this study between standardised measures of visual perception, as measured by the TVPS, and functional difficulties. Therapists are cautioned to explore both the evidence base for continued use of standardised visual perceptual measures to inform occupation-centred practice and the need to embrace a more comprehensive person-centred approach to visual perceptual assessment.
