The digital wave triggered by new technology has changed the traditional way of life. Digital media art, as the most cutting-edge part of contemporary art, has been gradually followed up with professional creation courses related to digital media in colleges and universities. Interactive device art creation course is an important practical course for digital media art major. Seek innovation points in multi-media platforms and conduct independent interdisciplinary creation, so as to learn interactive installation art creation in digital media art.At present, there are still some problems in the design of interactive device art creation course, which are mainly reflected in the following aspects:1. The teaching system is not comprehensive enough. The comprehensiveness and pioneering nature of interactive installation art make it require higher and more comprehensive professional quality of students. However, the current teaching system has problems such as single curriculum, lack of interdisciplinary integration and lack of special training.2. Lack of project management awareness. In the practical teaching of interactive installation art creation, due to the comprehensiveness and diversity of the course, students often need to organize a team to complete it. However, due to the lack of project management awareness, students are difficult to lack effective organization and management of complex projects such as interdisciplinary practice and media integration.3. The assessment and evaluation system is not comprehensive enough. The current curriculum assessment and evaluation system lacks an incentive mechanism for innovation, attaches too much importance to the training of new media art talents, and fails to assess the quality of students' innovation ability quantitatively. As a result, students have problems such as stylized creation and weak innovation consciousness, and a more perfect assessment mechanism for new media art education.In view of the above problems, by analyzing the concept of OBE and STEAM, the content and process of experimental teaching are optimized, and an online and offline experimental teaching mode of interactive installation art that integrates OBE and STEAM is constructed.

At the dawn of Urban Air Mobility (UAM), namely the introduction of eVTOL (electric Vertical Take-off & Landing) vehicles, we have been pioneering in designing a certifiable flight training programme for those pilots who will be the first in the world to operate such vehicles.This paper will discuss our training design path we pursued, the research and development work behind it and finally the resulting training design. Emphasis is laid on the analysis of the training needs, our design approach based on human-factors research and development, the requirements for the design of new flight simulators, and how a close cooperation with OEMs and aviation authorities made us validate this flight training programme course, which will prepare future eVTOL pilots for a safe and sustainable operation in Urban Air Mobility in just one year from now.

In recent years, Highly Sensitive Persons (HSP) have gained increasing attention. HSP refers to individuals with heightened sensory sensitivity, making them more sensitive to stimuli and frequently more empathetic. In this study, we focused on HSPs’ high empathy and their ability to detect subtle cues from facial expressions. We hypothesized that individuals with HSP tendencies are more likely to perceive and express minor changes in facial expressions. To test this hypothesis, we created deliberate facial expressions representing nine emotional states, i.e., happiness (four levels), neutrality (one level), and sadness (four levels). We measured mouth corner movements using the MediaPipe system, which is a webcam-based motion capture system. The subjects imitated 10 facial expressions, ranging from neutral to happy and sad, each with five levels of intensity. We then examined the correlations between the subjects’ facial expressions and psychological measures, including the Highly Sensitive Person Scale (HSPS) and the Japanese version of the Interpersonal Reactivity Index. The result exhibited correlations in specific intervals. First, there was a strong correlation in the five-level range from neutral to happy (r = 0.67). Second, there was a correlation in the interval from minor expression change from neutral to the second level of happiness (r = 0.50). Third, a correlation was observed in the interval from the second to the fourth level of happiness (r = 0.61). These results suggest that individuals with higher HSPS scores (indicating HSP tendencies) exhibit greater changes in facial expressions when experiencing happiness, which suggests that those with HSP tendencies are more receptive to subtle changes in intentional facial expression mimicking stimuli, particularly happiness.

Extended areas of the planet are experiencing drought, a natural phenomenon that occurs due to a prolonged period of abnormally low rainfall or when water is insufficient. Drought is a critical global problem affecting the environment, economies and social well-being of communities around the world, with severe impacts on agriculture, wildlife, water supplies and public health.The most efficient technique for protecting the soil against pedological drought is represented by mulching, a technique that enables the preservation of the soil moisture (by reducing evaporation) and limitation of the weed growth (lack of light forces etiolation and exhaustion). In addition, considering that an extraordinary variety of living beings could be developed under the mulch, the most important being represented by the Oligochaeta taxon and Annelida family, through mulching, digging and loosening operations are eliminated.The paper presents the stages of the incremental iterative development of a collapsible aerial module used for mulching the soil affected by extreme pedological drought, starting from the specific requirements imposed to the functional system by the real conditions of usage. The phases of iterative development were completed, starting from the digital and experimental design, the realization and testing of the system. Thus, the initialization phase included the digitization sequences corresponding to the digital design of the system and performance evaluation through testing (sketcher, part design, assembly design and generative structural analysis) for 3 distinct requirements: i) the module has a load with a mass of 5000 kg, t0=0 s; ii) part of the load is placed and there is a remaining part of 2000 kg, t1=t0+ɛ s, and iii) the module is empty, t2= t0+ɛ+ɤ s. The testing was carried out for all the 3 different situations as a function of time and the deformation under the effect of dynamic pressure, Von Mises stress fields and distribution of displacement vectors and errors were visualised.The possible cracks of the system were predicted using the Von Mises criterion, according to which the limit state of the solid body appears when the specific potential energy that modify the shape reaches the characteristic limit value of the material (allowable resistance of min +010N_m2). The second phase of the incremental development consists in the experimental design with the help of the Optitex Pattern Making PDS (EFI Optitex) software, obtaining the type-dimensions of the system and the multiplication (2D pattern construction, 3D simulation and visualization).The incremental development approach leads to a rapid development and realization of the functional model used in the case of pedological drought, and its systematic testing in real conditions of usage will determine both the improvement of the type-dimensional parameters, and the definition of the technological process.

In many different industries including IT, business, medicine, engineering, and many more, technology refers to a collection of methods and information that are used to develop, produce, and improve services and products. Technology has evolved quickly in recent years, and innovations have completely changed how we work, live, and interact with the world. For instance, the Internet has made it possible to access a vast quantity of information and quick communication through a variety of applications like Facebook and Instagram, and being able to swiftly access it on our phones enables us to be constantly connected to social networks and various other resources. As such, digital technologies offer a unique opportunity to improve educational standards. On the one hand, teachers and trainers become equipped with cutting-edge tools that help them engage their classroom with contextualized information in a way that is not only personalized and differentiated according to everyone's distinctive progress and needs but also time-efficient. Alternatively, students benefit from a customized learning experience that is also sensitive to their performance, sometimes through an immersive experience, to be able to go on and use their education to contribute to the society they will live in in the future. As such, the advantages of integrating digital technologies with pedagogy to develop an elevated learning environment have become increasingly apparent. Virtual reality is one of the most recent developments in technological innovation that is being used as a tool for educators in the educational process in nations with more developed economies. People are captivated by virtual reality because of the intriguing images, the distinctive experience it provides, and the way it captures their attention consistently. Immersion in a virtual space becomes an experience through which users can unconsciously integrate the knowledge, images, and content they are exposed to, which has a real and positive effect on their mental health. Training in fields where the direct experience could provoke more cognitive and behavioral damage is training teachers for children with special needs. As it offers a realistic and interactive experience in a regulated and safe setting, virtual reality can be a highly beneficial tool for the training and education of teachers working in such environments. In such an immersive environment, teachers can learn how to react appropriately and deal with challenging situations because a virtual reality application can simulate scenarios that imitate the distinctive behaviors of children. In these scenarios, each child's particular needs and preferences may be attended to, which might be challenging to imitate in the real world. The current work seeks to create experimental game scenarios tailored for special needs classroom training, assess their usefulness, and examine how they affect the growth of children's social and communicative abilities.

The development of digital technology is profoundly transforming the practice of medical education. Virtual simulation is becoming the cornerstone of clinical education and training. With the increasing budget and standardized teaching pressure of universities and related medical institutions, virtual reality is playing a more and more important role on medical simulation teaching. VR can provide cost-effective, repeatable, and standardized clinical training for learners and educators as needed. The future of VR lies in its continuous integration with the curriculum and the technological development that allows the sharing of simulated clinical experience. It can achieve large-scale medical education without time and space limitation, and change the way of future clinical education. Especially in the context of public health crises, virtual medical training systems can greatly alleviate the shortage of professionals in medical institutions, protect medical personnel, and obtain a large number of well-trained medical staff in the short term. As a powerful and highly potential medical education tool, Virtual reality has attracted high attention from top international medical colleges and institutions. This study analyzes the scenario innovation of virtual reality technology in medical education through a combination of theory and case studies, summarizes the possibilities, advantages, and barriers of technology use, and provides reference for the development of related virtual medical education systems.In terms of the possibility of scenario innovation, the following five points can be considered: firstly, virtual reality technology can showcase the functions of medical devices and drug action mechanisms in medical procurement and marketing; Secondly, for doctor-patient communication, education can be provided to medical patients and their families, informing and explaining the patient's condition, surgical operation plan, and the role of "trial operation"; Thirdly, for rehabilitation training, it can help patients receive dual psychological and physiological treatment and rehabilitation guidance; Fourthly, for medical teaching, nursing teaching and clinical training can be conducted; Fifth, for medical science popularization, health knowledge popularization, promotion of healthy lifestyles, emergency rescue training, and disaster response education can be carried out.

With the advance of Deep Neural Networks (DNN), the accuracy of various tasks in machine learning has dramatically improved. Image classification is one of the most typical tasks. However, various papers have pointed out the vulnerability of DNN.It is known that small changes to an image can easily makes the DNN model misclassify it. The images with such small changes are called adversarial examples. This vulnerability of DNN is a major problem in practical image recognition. There have been researches on the methods to generate adversarial examples and researches on the methods to defense DNN models not to be fooled by adversarial example. In addition, the transferability of the adversarial example can be used to easily attack a model in a black-box attack situation. Many of the attack methods used techniques to add perturbations to images in the spatial domain. However, we focus on the spatial frequency domain and propose a new attack method.Since the low-frequency component is responsible for the overall tendency of color distributions in the images, it is easy to see the change if modified. On the other hand, the high-frequency component of an image holds less information than the low-frequency component. Even if it is changed, the change is less apparent in the appearance of the image. Therefore, it is difficult to perceive an attack on the high-frequency component at a glance, which makes it easy to attack. Thus, by adding perturbation to the high-frequency components of the images, we can expect to generate adversarial examples that appear similar to the original image with human eyes.R. Duan et al. used a discrete cosine transformation for images when focusing on the spatial frequency domain. This was a method by use of quantization, which drops the information that DNN models would have extracted. However, this method has the disadvantage that block-like noise appears in a resultant image because the target image is separated by 8 × 8 to apply the discrete cosine transformation. In order to avoid such disadvantage, we propose a method which applies the wavelet transformation to target images. Reduction of the information in the high-frequency component changes the image with the perturbation that is not noticeable, which results in a smaller change of the image than previous studies. For experiments, the peak signal to noise ratio (PSNR) was used to quantify how much the image was degraded from the original image. In our experiments, we compared the results of our method with different learning rates used to generate perturbations with the previous study and found that the maximum learning rate of our method was about 43, compared to about 32 in the previous study. Unlike previous studies, the attached success rate was also improved without using quantization: our method improved attack accuracy by about 9% compared to the previous work.

Unlike previous studies, the attached success rate was also improved without using quantization: our method improved attack accuracy by about 9% compared to the previous work.","PeriodicalId":470195,"journal":{"name":"AHFE international","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135318044","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}

Following the success of remote work in the Business Process Outsourcing (BPO) industry during the Covid-19 pandemic, several organizations have considered choosing a permanent remote work policy for their employees over the traditional face-to-face setup. The primary determinants that dictate adopting a permanent working environment are often centered on cost-related considerations with little regard for the slow onset of occupational health hazards. Studies have identified various health hazards experienced by BPO personnel, including headaches, back pain, neck and shoulder discomfort, wrist and hand pain, eye strain, overweight, hearing loss, and digestion issues. Electromagnetic hypersensitivity (EHS) is a term used to describe such symptoms that manifest in response to exposure to electromagnetic field (EMF)-emitting devices. In the context of the Philippines, most are unaware of the potential implications of EMF exposure, hence it is worthwhile to closely investigate the EHS of BPO employees. This study aims to investigate the health-effects of EMF-emitting devices on BPO personnel in both traditional and remote work setups. The study used a web-based questionnaire to collect and assess data from two discrete populations. A self-reporting questionnaire (SRQ-20) was used to pre-assess the respondents’ general wellness and health status. Statistical significance was established using the independent t-test. Principal component analysis was used to identify the major symptoms associated with EHS, whereas the EMF sources were analyzed using an independent sample t-test with bootstrapping. Based on the SRQ-20, traditional BPO personnel encounter health risks with statistically higher severity (p < 0.05) than their remote counterparts which may infer that the two different working settings possibly have distinct effects on the health of the workers. However, upon further evaluation, the two distinct populations both exhibited negligible to moderate indications of EHS symptoms in separate environments. A significant difference in the perception of BPO workers is observed regarding the intensity of the effects of EMF across all possible sources except three specific devices: a computer, a television, and a television or radio transmitter. However, the source analysis indicates that the influence of EMF-emitting devices on the EHS of employees is low to negligible in both occupational settings. The study concluded that there is an absence of potential health risks stemming from exposure to EMF in both occupational settings for BPO employees. Considering the negligible impact of EMF exposure on EHS symptoms, BPO industries possess the flexibility to choose between the two work setups, as both environments do not pose significant EMF-related occupational health and safety threats.

Since the word “Metaverse” was first coined by the novelist Neal Stephenson in 1992, it has immediately shown endless charm and attracted many scientists, engineers, and geeks from all over the world to become its “vassals”. In recent years, with the development of virtual reality, blockchain and smart wearable devices, the idea of Metaverse seemed to be touchable and became a popular topic in academic literature. This study aims to highlight the influential authors, sources, institutions, and countries in the research of Metaverse through bibliometric analysis. 665 related documents from 1995 to 2023 January were collected and analyzed from the Web of Science Core Collection database. The R-tool Bibliometrix 4.0.0, and the software VOSviewer 1.6.19 were used to analyzed research trends. The results showed that almost 80% of the relevant documents was published in the past year. Wang Feiyue is the most relevant author with 17 articles. Sustainability, IEEE Access, and Applied Sciences Basel are influential journals in this field. Chinese Academy of Sciences is the most productive institution, and China is as well as the most productive country, while the United Kingdom is the most cited country. Furthermore, our study identified five research streams, which not only summarized current academic activities, but also provided potential directions for the future study.

Autonomy has found wide-ranging applications, yet its imperfect nature necessitates human oversight and intervention. Investigating autonomy's impact on the operator is pivotal for enhancing human-machine system performance and safety. This study analyzes the effects of autonomous system reliability on operator task performance and mental workload in the context of vehicle type recognition. Experimental findings reveal that autonomy with 90% reliability significantly reduces task completion time and lessens subjective workload. Autonomy with 70% reliability supports the participants, while 50% reliability hampers them, although insignificantly. The reliability threshold for autonomy to have no effect on the participants is around 55%. Autonomy reliability's influence on the operator lies in altering task completion strategies — an all-or-none approach that accelerates task processing speed without improving overall response accuracy. The experiment yielded insights applicable to the design of assistive autonomous systems and the allocation of human-machine functions in real-world tasks.
