The increased automation of the car manufacturing process, in which much of the assembly has been delegated from man to machine, has done much to relieve workers of the burden of heavy lifting. However, despite ergonomic improvements in the workplace, many jobs still require workers to perform repetitive tasks [1]. In the automotive industry, Work-related Musculoskeletal Disorders (WMSD) are one of the most common occupational problems due to repetitive working tasks. Workers that perform manual work are often prone to awkward postures, repetitive movements, forceful exertions, and overextensions, which are some of the main factors for the arising of WMSD [2]. Besides, these work-related factors, also the personal factors contribute to the occurrence of this kind of injury, making WMSD a complex condition that involves contributions from many factors [3,4]. The current study aims to compare different observational methods commonly used to assess the WMSD risk in repetitive tasks. To accomplish this goal a case of study in assembly workstation of an automotive company in Portugal was applied. It was selected methods that are widely used by ergonomists and are validated for implementation in the industry [5,6]. Therefore, the following methods were applied to an assembly workstation: (i) Rapid Upper-Limb Assessment (RULA), (ii) Occupational Repetitive Actions (OCRA), (ii) Key Indicator Method – Manual Handling Operations (KIM-MHO), and (iv) Revised Strain Index (RSI) This multi-method approach was very important, as it allowed for a more comprehensive assessment, which will support the proposals for improvement The results show that workstation present a considerable WMSD risk in 3 of 4 methods applied. These results suggest that a change to the workstation is necessary. A possible solution would be to implement a Human-robot collaboration solution, in order to reduce the physical demands associated with repetitive movements [7] to which workers are subjected.

汽车制造过程的自动化程度越来越高,其中大部分组装工作已从人交给机器,这大大减轻了工人搬运重物的负担。然而,尽管工作场所的人体工程学有所改进,但许多工作仍然需要工人执行重复的任务。在汽车工业中,与工作相关的肌肉骨骼疾病(WMSD)是由于重复性工作任务而引起的最常见的职业问题之一。从事体力劳动的工人往往姿势笨拙、动作重复、用力过猛和伸展过度,这些都是造成WMSD[2]的主要因素。除了这些与工作相关的因素外,个人因素也会导致此类伤害的发生,使WMSD成为一种复杂的疾病,涉及多种因素[3,4]。本研究旨在比较用于评估重复性工作中WMSD风险的不同观察方法。为实现这一目标,以葡萄牙某汽车公司的装配工作站为例进行了研究。所选择的方法被人类工效学家广泛使用,并在行业中得到了验证[5,6]。因此,将以下方法应用于装配工作站:(i)快速上肢评估(RULA)、(ii)职业重复动作(OCRA)、(ii)关键指标方法-手动处理操作(kimmho)和(iv)修订应变指数(RSI)这种多方法方法非常重要,因为它允许进行更全面的评估,这将支持改进建议。结果显示,在应用的4种方法中,有3种工作站存在相当大的WMSD风险。这些结果表明,更换工作站是必要的。一种可能的解决方案是实现人机协作解决方案,以减少与工人遭受的重复性运动[7]相关的体力需求。[1] Spallek m;库恩,w;Uibel,美国;范马克,A.;重复性工作引起的汽车工业中与工作相关的肌肉骨骼疾病-对康复的影响。j .

Toward Environmental Compatibility of Structural Forms 结构形式的环境相容性
Pub Date : 1900-01-01 DOI: 10.54941/ahfe100112
R. Tarczewski
Modern buildings are complex systems which have been in continuous interaction with man, for whom they are living and working environment. An important aspect of this interaction is the visual perception of the building and its relation to the natural environment. This is closely related to the evolution of architectural form and structural system of the building. The capabilities of the process of shaping the form are very much determined by the possibilities of adequate modeling of the building and the exchange of information between the participants of the investment process. Support for the modeling of buildings by means of using computer technology and numerical methods allowed to change the adopted aesthetic paradigm in architecture. One of the consequences of this development is the spread of organic forms, for which an obvious choice of the basic structural material has become concrete. It allows the formation of structural forms that previously could not be realized. However, technological limitations associated with the implementation of spatially complex concrete elements caused that after the initial enthusiasm, there has been a decline in their use. New opportunities offered by the application in the production of these structural elements of the flexible membranes made of technical textiles opens up a new perspective for the design of objects with forms integrated with the natural environment.
现代建筑是与人类不断互动的复杂系统,是人类的生活和工作环境。这种互动的一个重要方面是建筑的视觉感知及其与自然环境的关系。这与建筑形态和结构体系的演变密切相关。造型过程的能力在很大程度上取决于建筑的充分建模的可能性以及投资过程参与者之间的信息交换。通过使用计算机技术和数值方法支持建筑物的建模,可以改变建筑中采用的美学范式。这种发展的结果之一是有机形式的传播,因此基本结构材料的明显选择是混凝土。它允许形成以前无法实现的结构形式。然而,与空间复杂的具体元素的实施相关的技术限制导致在最初的热情之后,它们的使用有所下降。在生产这些由技术纺织品制成的柔性膜的结构元素的应用中提供了新的机会,为设计与自然环境相结合的形式的物体开辟了新的视角。

The actualization of the development of inclusive tourism is enhanced by the fact that for people with disabilities tourism is not only a means of recreation and rehabilitation, promotes the activation of motor functions and support of physical fitness, but also a source, creating an environment for full interaction and elimination of feelings of inferiority, that in turn mobilizes mental health resources and restores the psycho-emotional mood of a person, and therefore, increases the level of his/her self-esteem and self-significance. The article examines possible ways of developing inclusive tourism as a social service for people with disabilities. The state of the provision of rehabilitation services for people with disabilities to improve the level of full-quality life has been determined, and the feasibility of providing rehabilitation services through inclusive tourism among social field professionals. Recommendations for the development and implementation of inclusive tourism as a social service for people with disabilities are offered.
对于残疾人来说,旅游不仅是一种娱乐和康复的手段,促进运动功能的激活和对身体健康的支持,而且是一个来源,创造一个充分互动和消除自卑感的环境,从而调动心理健康资源,恢复一个人的心理情绪情绪,因此,促进了包容性旅游发展的实现。提高他/她的自尊水平和自我意义。本文探讨了发展包容性旅游作为残疾人社会服务的可能途径。确定了为残疾人提供康复服务以提高全质量生活水平的现状,以及社会领域专业人员通过包容性旅游提供康复服务的可行性。提出了发展和实施全纳旅游作为残疾人社会服务的建议。

Of all the events that contribute to deaths due to preventable medical errors in healthcare, ineffective communication is one of the most frequently identifiedprimary causes. Failure to speak up or to get others to listen is part of this ineffective communication. Therefore, speaking up behavior of healthcare workers is seen as an important factor to improve patient safety. However, more research is needed to understand 1) the most important influencing factors of speaking up behavior, 2) what kind of speaking up behavior is used and is most effective in preventing adverse events and 3) what is the role of the receiver and the work environment.

Designing a Tool to Support Patient Safety: Using Research to Inform a Proactive Approach to Healthcare Facility Design 设计支持患者安全的工具:利用研究为医疗设施设计提供主动方法

Healthcare architecture has become an increasingly specialized field, marked by a complex interaction between people, operations and the physical environment and an ever changing landscape of regulation and reimbursement. Patient safety is often considered in a behavioral context – what can someone do differently to improve outcomes? However, as a complex system of interactions, patient safety is better advanced through a systems-thinking lens of Human Factors/Ergonomics (HFE). Attaianese and Duca commented on the use of HFE principles in design, stating that, “when the system is the built environment, the systemic approach requires that designers move from an attention exclusively reserved for building functions towards the set of actions that users actually perform and that building has to support.” This paper reports the development of a proactive Safety Risk Assessment (SRA) tool which will contribute to the 2014 Facility Guidelines Institute (FGI) Guidelines for the Design and Construction of Hospitals and Outpatient Facilities. Six hazard areas have been considered as underlying conditions to injury or harm in the design of healthcare environments: 1) Hospital Associated Infections, 2) Falls/Immobility, 3) Medication Safety, 4) Patient Handling, 5) Security, and 6) Behavioral Health/Psychiatric Injury. These categories have been developed using iterative cycles of Delphi and nominal group methods to achieve consensus of categories and question sets for inclusion in the SRA.
医疗保健架构已成为一个日益专业化的领域,其特点是人员、操作和物理环境之间的复杂互动,以及不断变化的监管和报销环境。患者安全通常是在行为的背景下考虑的——人们可以采取什么不同的措施来改善结果?然而,作为一个相互作用的复杂系统,通过人因/人体工程学(HFE)的系统思维镜头,患者安全得到了更好的提高。Attaianese和Duca评论了HFE原则在设计中的应用,他说:“当系统是建筑环境时,系统方法要求设计师从专门关注建筑功能转向用户实际执行的一系列行为,以及建筑必须支持的行为。”本文报告了一种主动安全风险评估(SRA)工具的开发,该工具将有助于2014年设施指南研究所(FGI)医院和门诊设施设计和建造指南的制定。在医疗保健环境的设计中,有六个危险区域被认为是伤害或伤害的潜在条件:1)医院相关感染,2)跌倒/不动,3)药物安全,4)患者处理,5)安全,以及6)行为健康/精神伤害。这些类别是使用德尔菲迭代循环和名义群体方法开发的,以达成类别和问题集的共识,以便纳入SRA。

During COVID-19 pandemic, schools worldwide were compelled to embrace remote classrooms, relying more heavily on Digital and Social Media (DSM) to deliver lessons. This paper suggests a website as a digital solution, and it provides an insight from teachers and students’ perceptions on utilizing it by investigating the impacts of using the website in one of Qatar preparatory schools. A qualitative approach is followed to analyze the obtained data from interviews via qualitative coding technique.  The results show that students were increasingly motivated and interested in topics related to sustainability and environmental issues pertinent to the case of Qatar after posting on the website. Furthermore, findings from teachers’ perspectives reveal that the ease of sharing, commenting, and documenting students’ reflections made them more prone to use the website. The study concludes with a set of recommendations to improve DSM learning in Qatar.
在2019冠状病毒病大流行期间,世界各地的学校被迫采用远程教室,更多地依赖数字和社交媒体(DSM)来授课。本文建议将网站作为一种数字解决方案,并通过调查卡塔尔一所预科学校使用该网站的影响,从教师和学生对利用该网站的看法中提供了见解。通过定性编码技术,采用定性方法对访谈数据进行分析。结果显示,学生们在网站上发帖后,对与卡塔尔案例相关的可持续发展和环境问题的话题越来越感兴趣。此外,从教师的角度来看,研究结果表明,分享、评论和记录学生反思的便利性使他们更倾向于使用该网站。该研究最后提出了一套改善卡塔尔DSM学习的建议。

Digitalization in Public Care – Consequences on Workflow and Attitudes among Care Givers and Older Adults 公共护理中的数字化——对护理人员和老年人工作流程和态度的影响
Pub Date : 1900-01-01 DOI: 10.54941/ahfe1001669

To be able to meet the demographical changes and the increasing demand on resources within elder care, new digital tools are needed to an increasing extent. Implementation of new digital services demand both changes in workflow and skills in using the digital services. The feeling of being included in the process and time given for learning and introduction could affect how new digital tools are perceived by the personnel. However, time and resources for learning and support could vary between municipalities, and between units within the same municipality (Sjölinder & Mårtensson, 2021). Though both resources are limited, and it is important how new digital services are introduced to the personnel more in-depth knowledge is needed regarding which aspects that needs to be given the largest focus.With respect to older adults, there exist many assumptions and negative stereotypes regarding aging (Lagacé et al., 2015; McDonough, 2016), and about older adults as users of new digital services (Lagacé, et al, 2016; McDonough, 2016). However, many older adults today have experience from using technology and are in general positive to start to use new digital services, but as in the case with the personnel, the learning context and the time that is provided are important (Broady, 2010; Sjölinder & Mårtensson, 2021). When new digital tools are provided to the older adults by the municipality, the learning context for the older adults might be affected by the care givers time and engagement, which in turn could affect the attitudes that are conveyed to the older users about older adults as users of technology.This paper describes a qualitative study with the aim to get a deeper understanding of opportunities and challenges related to digitalization within municipalities. The focus is on how new digital tools have been implemented in the organizations, and on how it had affected care personnel and older care takers. This, in terms of how and to which extent has implementation of new digital tools changed work-related behavior and attitudes towards technology, and to which extent has it changed attitudes towards older adults as technology users.In the study, municipality managers at different levels where interviewed. They described concrete examples of digitalization based on experiences from within their own organization. Using the examples that were given, the respondents were asked questions about how the technology had been received by the personnel and the older adults; how it had affected the attitudes towards new digital tools among the care giving personnel and older adults; and how it had affected the way the personnel thought about organizational changes and changes in workflow related new digital tools. Finally, the respondents described, based on their own previous insights, the municipalities’ next steps towards digitalization, and how they wanted to use new digital tools to take their organizations further towards the future.
为了满足人口结构的变化和对老年护理资源日益增长的需求,越来越多地需要新的数字工具。实施新的数字服务需要改变工作流程和使用数字服务的技能。参与过程的感觉以及学习和介绍的时间可能会影响员工对新数字工具的看法。然而,学习和支持的时间和资源可能因城市而异,也可能因同一城市内的单位而异(Sjölinder & ma rtensson, 2021)。尽管这两方面的资源都是有限的,而且如何向员工介绍新的数字服务也很重要,但需要对哪些方面需要给予最大的关注有更深入的了解。对于老年人,存在许多关于衰老的假设和负面刻板印象(lagac等人,2015;McDonough, 2016),以及老年人作为新数字服务用户的情况(lagac等人,2016;麦克多诺,2016)。然而,今天许多老年人都有使用技术的经验,并且总体上积极地开始使用新的数字服务,但就人员而言,学习环境和提供的时间是重要的(broad, 2010;Sjölinder & ma rtensson, 2021)。当市政当局向老年人提供新的数字工具时,老年人的学习环境可能会受到照顾者的时间和参与的影响,这反过来又可能影响向老年用户传达的关于老年人作为技术用户的态度。本文描述了一项定性研究,旨在更深入地了解与城市数字化相关的机遇和挑战。重点是如何在组织中实施新的数字工具,以及它如何影响护理人员和老年护理人员。这是关于新数字工具的实施如何以及在多大程度上改变了与工作相关的行为和对技术的态度,以及在多大程度上改变了对老年人作为技术用户的态度。在研究中,不同层次的市政管理者接受了采访。他们根据自己组织内部的经验描述了数字化的具体例子。根据给出的例子,受访者被问及有关工作人员和老年人如何接受这项技术的问题;它如何影响护理人员和老年人对新数字工具的态度;以及它是如何影响员工对组织变化的看法以及与新数字工具相关的工作流程变化。最后,受访者根据自己之前的见解,描述了市政当局走向数字化的下一步措施,以及他们希望如何使用新的数字化工具使其组织进一步走向未来。

Human Concepts Applied on School Design 人文理念在学校设计中的应用
Pub Date : 1900-01-01 DOI: 10.54941/ahfe100593
Elza Cristina Santos
The project to an early childhood school started from this problematic: why do not schools offer efficient quality spaces to early childhood education? As an answer, it was suggested that the school building, besides presenting a fitting spatial solution to a pedagogical proposition, should consider playing as a very important activity in the learning process. Have been considered the hypothesis that most schools do not present appropriate environments for child education and that playful activity in a complex scholar space is essential to this process. The confirmation of these hypothesis led to an idea which embraces the human concepts of welcoming, complexity, versatility, transparence and playfulness, determinative to the project guidelines: integration with the community; open sketch/nature interaction; school as a small learning community; natural lighting and ventilation; cozy environments; walking as a learning tour; adaptability/flexibility/variety; transparence and passive supervision; architecture that teaches/sustainability; exterior spaces and playful stimulus; material, textures and colors as identity elements.
这个早期儿童学校的项目是从这个问题开始的:为什么学校不能为早期儿童教育提供高效、优质的空间?作为回答,有人建议学校建筑除了为教学命题提供合适的空间解决方案外,还应考虑将玩耍作为学习过程中非常重要的活动。大多数学校没有为儿童教育提供合适的环境,而在复杂的学生空间中进行有趣的活动对这一过程至关重要。这些假设的确认导致了一个想法,它包含了人类的欢迎、复杂性、多功能性、透明度和游戏性的概念,决定了项目的指导方针:与社区融合;开放素描/自然互动;学校作为一个小型学习社区;自然采光和通风;舒适的环境;步行是一次学习之旅;适应性/灵活性/品种;透明和被动监督;教授/可持续发展的建筑;外部空间和好玩的刺激;材料,纹理和颜色作为身份元素。
