A worker may experience muscle aches or numbness in legs and fatigue after an eight-hour workday occupying a permanent posture for a long time. Taking into account minimum requirements for postural hygiene and ergonomics, we managed to avoid these discomforts without suffering health problems in the medium and long term. This study is part of a population of fifteen craftsmen who make masapan handicrafts in Calderón town in Ecuador. The process arises from a transformation of bread dough to a handmade dough more than 80 years ago, consisting of an ancestral art that needs quality from obtaining the dough to the artistic details of figures, where the craftsman makes his creations without realizing that is jetting a bad posture in the workplace. The research analyzes the operation of the manufacture of the glue that is carried out standing up, mixing the ingredients to obtain the dough and cooked until it gets a homogeneous consistency. It is a repetitive activity in each of the production cycles. The OWAS and RULA methods were applied to assess the risks produced by physical loads derived from the activities carried out and the global characterization of the postures, which were observed and classified in various possible combinations. The process is at level 3, that is, it requires the redesign of the task and increasing the active pauses. As a result, it was obtained that the risk category is level 2, the analyzed posture has the potential to cause damage to the musculoskeletal system.

The main purpose of this paper is to review the effectiveness of Permit to Work (PTW) systems within current academic literature and build an understanding of what recommendations can be implemented to establish a PTW system that conclusively manages the risk and hazards that people undertaking high risk and non-routine work are exposed to. PTW is a control system that is used to assess and manage the hazards associated mostly with high risk work, such as work at height, hot work, electrical work or confined spaces as well as non-routine work. Failure of the PTW system can have catastrophic consequences as seen in the Piper Alpha oil platform explosion where 167 people were killed, the Longford Gas release and explosion where two people were killed and the Phillips Chemical Company fire at Pasadena where there were 23 fatalities. For this article the search terms ‘Permit to Work’, ‘Permit-to-Work’, ‘Hot Work Permits’ were used to retrieve journal articles on PTW systems from the University of Newcastle’s library database. Two further criteria were applied - firstly, the article must be published after 1990 allowing for the last 30 years of major incidents to be captured, and secondly, any article that was attempting to sell a particular product was excluded as these articles were not reviewing PTW systems or major incidents causes but rather the effectiveness of their own products. In every system there are strengths and weaknesses. In reviewing the literature on PTW systems, five key weaknesses were identified: inadequate training, deficiencies of paper based PTW systems, failure of effective handover at shift change, weak leadership commitment to the PTW system and inadequate auditing scheduling and techniques. A PTW system must have a comprehensive handover procedure between shifts. If there is capacity to implement an electronic PTW system then this is preferrable to a paper-based system as long as it is customisable and covers all the requirements of a what is considered as a robust PTW system including: the authorised personnel, limitations of each permit, hazards and precautions identified through risk assessment, the permit’s validity time frame, handover and closure. In this review, it will be demonstrated that a PTW system that considers the five key deficiencies and overcomes these can be an effective PTW system.
本文的主要目的是在现有的学术文献中回顾工作许可证(PTW)制度的有效性，并了解可以实施哪些建议来建立一个PTW制度，以最终管理从事高风险和非常规工作的人所面临的风险和危害。PTW是一种控制系统，用于评估和管理主要与高风险工作相关的危害，例如高空工作，高温工作，电气工作或密闭空间以及非常规工作。PTW系统的故障可能会导致灾难性的后果，例如导致167人死亡的Piper Alpha石油平台爆炸，造成2人死亡的Longford天然气泄漏和爆炸，以及造成23人死亡的Phillips Chemical Company火灾。对于这篇文章，搜索词“工作许可”，“工作许可”，“热工作许可”被用于从纽卡斯尔大学图书馆数据库检索关于PTW系统的期刊文章。另外还适用了两个标准——首先，文章必须在1990年之后发表，允许捕获最近30年的重大事件;其次，任何试图销售特定产品的文章都被排除在外，因为这些文章不是审查PTW系统或重大事件原因，而是审查其自身产品的有效性。每个系统都有优点和缺点。在回顾有关PTW系统的文献时，我们发现了五个关键弱点:培训不足、纸质PTW系统的缺陷、换班时有效交接的失败、领导层对PTW系统的承诺不强以及审计计划和技术的不足。PTW系统必须有全面的轮班交接程序。如果有能力实施电子PTW系统，那么这比基于纸张的系统更可取，只要它是可定制的，并且涵盖了被认为是一个强大的PTW系统的所有要求，包括:授权人员、每个许可证的限制、通过风险评估确定的危害和预防措施、许可证的有效时间框架、移交和关闭。在这篇综述中，将证明一个考虑到五个关键缺陷并克服这些缺陷的PTW系统可以是一个有效的PTW系统。

This paper presents a fast and lightweight image inpainting method using distance transform and Gaussian lowpass filtering on disoccluded regions for virtual view synthesis. Virtual views are created from one texture-plus-depth image and afterwards a described method is used for the hole filling process. Proposed algorithm is compared with several state-of-the-art image inpainting methods using different no-reference image quality measures (BRISQUE, NIQE, PIQE). Results for the proposed method show competitive performance, while having lower execution time, concluding that the proposed method can be used in different real-time scenarios.

The executive functions that are at the core of human neuropsychological functioning are attention and memory. Attention encompasses a series of brain subprocesses that allow an individual to focus his/her state of consciousness on a determined stimulus of internal and external reality. On the ohter hand, memory refers to the capacity to store and recall information. The aim of the research was to develop a smartphone application that allows stimulate memory and older adults. This artiche describes the conceptual proposal that was followed to develop a smartphone application that seeks to improve the functioning of these two brain abilities named DR. LOBUS. This application includes a series of exercises that stimulate various sub-levels of attention and memory, such as selective and sustained attention, as well as immediate memory capacity.

Although more and more functions are integrated into the center touch screens, many researchers have proved that touch screens might distract drivers’ attention and cause accidents. Voice controls were also proved mentally straining and takes long interaction times.This article explored the practicability of multi-touch sliding gesture operations, basing on multi-touch screens or touchpads that are already widely used in vehicles. We built a multi-touch sliding gesture In-Vehicle Infotainment (IVI) system and a traditional touch IVI system, then evaluated them from both subjective and objective perspectives. The results are very positive: by using sliding gesture operations, the eye off-road time reduced 87.3%, the off-lane counts reduced 86.84% and the accident rate reduced from 7.5% to 0%. The driving activity load score reduced by more than half and the User Experience Questionnaire scored 2 ranks better.

Understanding driver’s maneuver behavior is an important prerequisite for providing drivers with different levels of assistance in the collaborative driving system. Aiming at establishing a general and interpretable model of driver steering styles, 38 drivers’ data are collected by a driving simulator platform, where a U-shaped experimental scene is built. To reduce data redundancy, Principal Component Analysis (PCA) is utilized to extract key features. Vali-dated by both Elbow Method and Silhouette Coefficient, the features are classified by k-means cluster. Finally, three driving styles with different characteristics are defined, and the corresponding original data are compared to make a reasonable explanation. The results can be used as a design basis for customizing shared steering controllers in collaborative driving.

The European Parliament stresses that the Internet is now an essential tool not only for accessing information and communicating with others, but also for many other daily activities, as it allows access to many services. Therefore, it is very important in the process of enabling participation in democracy and social inclusion. European Parliament has ensured that current standards for its products and content are met, including those to be heard in the EU Web Accessibility Directive, which came into force in December 2016. EU members have committed to taking appropriate measures to ensure access for people with disabilities on an equal basis with others from September 2018. Almost three years have passed since this law came into force and it is questionable how the law has been interpreted and applied to websites of public bodies and services. This paper examines the extent to which the legislation has affected the accessibility of public sector websites of EU member countries.

Human-Robot Collaboration (HRC) systems are often chosen to improve ergonomics in manual tasks. There are many metrics available to quantify the ergonomic benefits when implementing an HRC. It is important to understand which metrics (ergonomic methods, tests, questionnaires) are being used by researchers in terms of physical and mental workloads assessment. Therefore, this work aimed to review the literature on the subject and to provide key information for further investigations. A literature review was carried out in four databases and the findings were categorized into theoretical surveys and empirical studies from the last five years. Results show the emerging research fields that were identified and analyzed. The metrics used to assess physical and mental workloads were discussed and a new meaning for these results is proposed in the sense of using a global ergonomic risk assessment as input in simulation models.

The world in recent times has experienced an unprecedented advance in the development of Information and Communication Technologies (ICT), as indicated by United Nations Organization (UN) in 2019. The UN highlights that the influence of new digital technologies has transformed society, reaching more than 50% of the world's population in the last 20 years. Thus, virtual learning environments (VLE) have become spaces where it has been possible to move the classroom to virtual world. This technology has introduced new methodologies, interactive material, and various ways of presenting information. This study proposes the development of a virtual learning environment as a space to study the topic of internal combustion engines, applying digital narratives methodology. Through bibliographic and documentary research, it has been found that this strategy fosters various capacities in students, based on visual and auditory stimulation, facilitating learning and retention of information. For the development of the virtual classroom, the theme will focus on the theoretical study of the internal combustion engine operating cycle. To accomplish this, the Moodle platform has been used, considering it the most suitable because its design provides both students and teachers with a personalized, robust, and safe environment. The functionalities of the virtual classroom will consist of providing the student with a visually attractive space both in structure and content. For this, there will be tools, Moodle environment typical activities and others that are avail-able online, which facilitate the creation of educational content. The pro-posed prototype seeks to become a space that complements the work developed in conventional learning. Thus, the contents of the virtual classroom are intended to bring the student closer to the subject to be developed in class and afterwards consolidate what has been learned. With this, it is expected to improve academic performance through constant motivation towards the study of the subject, also contributing to collaborative work before, during and after face-to-face sessions.
