This paper aims to assess the usability of electronic books (e‐books) and paper books (p‐books) with objective measures, including user comprehension, eye fatigue, and perception.

A total of 56 sixth‐year public school students participated in this study. This paper was conducted in the following order: pre‐CFF measurement, p‐/e‐book reading, post‐CFF measurement, quiz, and questionnaire. A standard CFF device, a computer with a monitor for reading e‐books, p‐books, desks, and chairs were provided.

This paper found that there is a significant “book effect” on quiz scores; compared to e‐books, p‐books appear to enable better reading comprehension. Regarding eye fatigue, students had significantly greater eye fatigue after reading e‐books than after reading p‐books. Students were satisfied with the e‐book, but they preferred p‐books.

Students would show satisfaction with e‐books and acknowledge their usefulness, but still prefer p‐books. However, a clearer understanding of this paradox in perception is needed. Further studies should try to explore the students' perceptions of e‐books.

Surprisingly, though, Korean students studied herein, who have had a higher level of exposure to technology than those in other countries, did not show positive behavioral intentions toward e‐books. Overall, the responses from the Korean students suggest that there was general satisfaction with reading e‐books on screen. However, this study also found a discordance in the students' perceptions of e‐books. In this study, most students grew tired of reading on the screen; this tiredness could have an adverse effect on both reading comprehension and the perception of e‐books. In further analyzing user responses, many of the critical remarks were found to refer to the screen/text size or clarity rather than to the e‐book itself.

Although this study suggests that students in general are not yet ready to entirely give up p‐books, e‐books are becoming increasingly common. However, great challenges remain in terms of making e‐book content more available and in enabling improved comprehension and reducing eye fatigue.

MUCH has been written about industrial engineering, especially in regard to American practice, but a good deal of confusion still exists about the whole subject.

Ninety per cent of the information used in performing one's daily work — whatever its nature — reaches the brain via the eyes. These eyes therefore must be working efficiently before the worker himself can do so.

Virtual reality (VR) offers unprecedented immersion and interactivity in education, and working and learning from home have become the norm during the COVID-19 pandemic. This study empirically investigated the factors affecting the use of a VR online learning system (VROLS).

To explore factors affecting users’ continuance behavioral intentions toward using VROLSs, a research framework was formed comprising factors that constitute benefits (i.e. pull factors) and costs (i.e. push factors); these factors included perceived value, flow and social influence. The data for this study were collected via online survey questionnaires. A total of 307 valid responses were used to examine the hypotheses in the research model, employing structural equation modeling (SEM) techniques.

Perceived value, flow experience and the number of peers using VR primarily affect the decision to adopt a VROLS. The pull factors of spatial presence, entertainment and service compatibility, along with the push factors of complexity and visual fatigue, affect perceived value. Therefore, we conclude that perceived value is a primary factor positively influencing both flow experience and the decision to adopt the service.

This study contributes to a theoretical understanding of factors that explain users’ intention to use VROLSs.

The purpose of this paper is to build a comprehensive structural model to demonstrate the interrelationships of factors influencing social networking service (SNS) fatigue and to identify the varying degrees of influence.

A total of 14 factors influencing SNS fatigue are identified through an extensive literature review. Interpretive structural modeling (ISM) and Matrice d'Impacts Croisés Multiplication Appliqué à un Classement (MICMAC) analysis are employed to build a hierarchical model and classify these factors into four clusters.

The results revealed that ubiquitous connectivity and immediacy of feedback are key factors contributing to SNS fatigue through their strong influence on other factors. Privacy concern, impression management concern and work–life conflict lead directly to SNS fatigue. In contrast, system feature overload and system pace of change are relatively insignificant in generating SNS fatigue.

This study represents an initial step toward comprehensively understanding the interrelationships among the factors leading to SNS fatigue and reveals how determinants of SNS fatigue are hierarchically organized, thus extending existing research on SNS fatigue. It also provides logical consistency in the ISM-based model for SNS fatigue by grouping identified factors into dependent and independent categories. Moreover, it extends the applicability of the integration of the ISM and MICMAC approaches to the phenomenon of SNS fatigue.

The purpose of this paper is to evaluate health effects and determine the factors associated with health effects from smartphone and tablet use among the elderly in Thailand.

This study was a cross-sectional descriptive study. The participants comprised 490 elderly people. A self-administered questionnaire was used for data collection via the Healthy e-Elderly People Assessment mobile application in the Android operating system by Google which consists of five parts of a questionnaire. The variables were analyzed using SPSS such as frequency, percentage, mean and binary logistic regression.

Altogether, the participants were 223 males and 267 females; mean age=64.9±5.4. The average time spent using a mobile device was 2.8±1.9 h/day. Participants recorded that after use of either device, 59.0 percent experienced eye pain, 52.7 percent experienced dim eyes, 30.2 percent experienced tiredness, and 28.0 percent experienced moodiness. Socially, 26.8 percent recorded changes in social interaction. Periods of time using devices, time consumed in device usage (hours/day), the type of application, and the difference in times of use, place of usage and time spent in rest breaks from smartphone or tablet usage were significantly associated with health effects (p<0.05).

The elderly users may be at risk of several health effects from smartphone and tablet use. The potential gap in knowledge conceals some of the risk factors for the current health effects. Practical intervention to reduce health effects from the use of smartphones and tablets should be considered.

The study aims to determine the level of e-reading habits and preferred electronic reading materials among nursing college students. The study examines students’ problems and difficulties using electronic resources and their knowledge of electronic literacy. Over the recent years, worldwide interest in reading electronic books has skyrocketed.

This study uses a survey research design and a structured closed-ended questionnaire as the data collection instrument. The sample population consists of college students. The study uses a quantitative method to investigate this population’s e-reading habits and preferred electronic reading materials.

The study findings indicate that while students prefer electronic resources, they need help accessing them due to various factors such as cost and availability. The survey results show that libraries must subscribe to a broader range of electronic resources, and academics and publishers must promote open-access articles to address these limitations.

The study addresses a current issue of students’ reading habits and preferred electronic reading materials and examines the limitations they face in accessing these resources. This research concludes that 21st-century students have transitioned from traditional to digital reading habits. They have a preference for electronic resources but their access to these resources is limited.

The objective of this research is to propose an immersive framework that integrates virtual reality (VR) technology with directives international safety training certification bodies to enhance construction safety training, which eventually leads to safer construction sites.

The adopted methodology combines expert insights and experimentation to maximize the effectiveness of construction safety training. The first step was identifying key considerations for VR models such as motion sickness prevention and adult learning theories. The second step was developing a game-like VR model for safety training, with multiple hazards and scenarios based on the considerations of the previous step. After that, safety experts evaluated the model and provided valuable feedback on its alignment with international safety training practices. Finally, the developed model is tested by senior students, where the testing format followed the Institution of Occupational Safety and Health (IOSH) working safely exam structure.

An advanced immersive VR safety training model was developed based on extensive lessons learned from the literature, previous work and psychology-informed adult learning theories. Model testing – through focus groups and hands-on experimentation – demonstrated significant benefit of VR in upgrading and complementing traditional training methods.

The findings presented in this paper make a significant contribution to the field of safety training within the construction industry and the broader context of immersive learning experiences. It also fosters further exploration into immersive learning experiences across educational and professional contexts.

The study aims to examine the effect of inclusions and inherent microstructure on fatigue behavior of 34Cr2Ni2Mo steel.

Fatigue behavior of 34Cr2Ni2Mo steel was investigated for up to 1E10 cycles.

Results showed that both inclusion and inherent microstructure have an influence on the crack initiation mechanism. Fatigue cracks mostly initiated from inclusions, whereas substrate-induced crack initiations were also observed. Fatigue life of inclusion-induced failures is mostly determined by the location of inclusions rather than the loading stress. The inherent microstructure seems to tolerate inclusions at a lower stress level in very high-cycle regime owing to the absence of internal inclusion-induced failure. For the substrate-induced crack initiations, high-density dislocations are found to be accumulated around the carbide particle-matrix interface, which may be the cause of crack initiation in the inherent structure due to strain localization.

The purpose of this preliminary study is to identify the e‐book utilization habit of postgraduate and undergraduate students from the Mathematics Department of Universiti Putra Malaysia (UPM), and to determine the reasons why students are feeling comfortable or uncomfortable with the e‐book services offered by the library and the role the librarians can play in solving the identified obstacles.

A qualitative approach which employs a face‐to‐face interview session was used to collect information on e‐book utilization habit and to capture perception of the e‐book services offered by UPM library.

This research found that most of the participants use one common e‐book reading habit. Factors such as easy access reduce physical visits to the library and user‐friendly features offer a comfortable platform for the participant to use the mathematics e‐books. However, unreliable service, eye fatigue, lack of manipulability of online features and flaws in the physical design and insufficient e‐book collection cause the participants to feel uncomfortable with the service. Moreover, the role of librarians, publishers and interface designers is perceived to be an important remedy for all the inconvenience incurred.

Only 70 participants participated in this preliminary study. Furthermore, e‐books from a single publisher (SIAM) were used to collect data from the participants. Hence, the size of the population surveyed and usage of a single mathematics e‐book publisher placed certain limitations on the level of detail in which the data collected could be analysed and summarised.

The study is important in terms of obtaining a better understanding of e‐book reading habits among mathematics students and the factors that cause them to feel comfortable and frustrated with the e‐book service offered by the library.

This is believed to be the first published study of mathematics students' reading habits and their perception using e‐book in UPM.
