Computer vision and deep learning (DL) methods have been investigated for personal protective equipment (PPE) monitoring and detection for construction workers’ safety. However, it is still challenging to implement automated safety monitoring methods in near real time or in a time-efficient manner in real construction practices. Therefore, this study developed a novel solution to enhance the time efficiency to achieve near-real-time safety glove detection and meanwhile preserve data privacy.

The developed method comprises two primary components: (1) transfer learning methods to detect safety gloves and (2) edge computing to improve time efficiency and data privacy. To compare the developed edge computing-based method with the currently widely used cloud computing-based methods, a comprehensive comparative analysis was conducted from both the implementation and theory perspectives, providing insights into the developed approach’s performance.

Three DL models achieved mean average precision (mAP) scores ranging from 74.92% to 84.31% for safety glove detection. The other two methods by combining object detection and classification achieved mAP as 89.91% for hand detection and 100% for glove classification. From both implementation and theory perspectives, the edge computing-based method detected gloves faster than the cloud computing-based method. The edge computing-based method achieved a detection latency of 36%–68% shorter than the cloud computing-based method in the implementation perspective. The findings highlight edge computing’s potential for near-real-time detection with improved data privacy.

This study implemented and evaluated DL-based safety monitoring methods on different computing infrastructures to investigate their time efficiency. This study contributes to existing knowledge by demonstrating how edge computing can be used with DL models (without sacrificing their performance) to improve PPE-glove monitoring in a time-efficient manner as well as maintain data privacy.

This study aims to investigate the consumer acceptance of robots in hotels before and after COVID-19, with a specific emphasis on whether COVID-19 had a significant effect on the acceptance of robots by hotel guests and whether guests had higher levels of acceptance of hotel robots since the initial COVID-19 outbreak was brought under control in China.

The sample for this research included Chinese hotel guests before and after COVID-19, with 247 responses obtained before its outbreak and a further 601 responses gathered after. Several hypotheses were developed and tested in a pseudo-experimental design.

The results showed that COVID-19 increased hotel guest acceptance of robots. After COVID-19, the perceived importance of the usefulness, social influence, attitude and value of robots increased, while the perceived importance of the ease of use and anthropomorphism of robots decreased. As a contactless service, the usefulness of robots was more valued by customers. This led customers to lower their requirements for the ease of use of robots. In addition, people were more concerned about the social influences on robot use.

Hotel guest attitudes and behavioral intentions toward robots and the services they can provide are changing. However, whether this change is purely ephemeral and motivated by a pragmatic stance triggered by COVID-19 remains to be established.

The hospitality industry is encouraged to create a new profile of guests in terms of their favorable or unfavorable disposition toward being served by robots. Hotels should consider the deployment of robots according to the demographic characteristics of customers (e.g. according to guest age levels).

This research demonstrated that major crises affect customer attitudes and behaviors toward new technologies. COVID-19 resulted in guests paying more attention to the advantages of services offered by hotel robots as a means of reducing the probability of contagion.

疫情前后酒店机器人非接触式服务的技术接受度对比研究

摘要

本研究调查了新冠疫情爆发前后酒店顾客对机器人接受程度的变化, 重点研究了新冠疫情是否对机器人的潜在接受程度有显著影响, 以及自疫情在中国得到控制以来, 顾客对酒店机器人的接受程度是否有所提高。

本研究的样本主要是新冠疫情爆发前后的中国酒店顾客, 在疫情爆发前收集了217份样本, 在疫情爆发后收集了601份样本。研究提出了若干假设, 并采用伪实验设计进行了检验。

结果显示, 新冠疫情的爆发提高了酒店顾客对机器人的潜在接受度。新冠疫情后, 机器人的有用性, 社会影响, 态度和价值的影响增加了, 而机器人的易用性和拟人化的影响降低了。由于机器人的无接触服务, 使得顾客更加关注有用性。这导致顾客对易用性的关注降低。此外, 顾客更加关注使用机器人的社会影响。

酒店顾客对机器人服务的态度和行为意图正在发生变化。然而, 这一变化是否是短暂的, 只是由新冠疫情驱动的, 仍有待确定。

我们鼓励酒店业根据客人对机器人的接受/不接受程度来创建一个新的客户档案。酒店也可以根据顾客的人口统计学特征（比如年龄）来部署机器人。

这项研究表明, 重大灾难会影响顾客对新技术的态度和行为。 COVID-19的爆发导致客人更加关注酒店机器人的服务优势（降低传染概率）。

Aceptación de la tecnología antes y después de la pandemia del COVID-19: Servicios ofrecidos por robots en hoteles

Resumen

Esta investigación analiza la aceptación por parte de clientes del uso de robots en hoteles antes y después del comienzo de la pandemia del COVID-19, prestando una atención especial a si dicha pandemia ha tenido un efecto significativo sobre los niveles de aceptación de robots por parte de clientes en hoteles en China a raíz de la pandemia del COVID-19.

La muestra de este estudio incluye clientes de hoteles en China encuestados antes y después del brote de COVID-19, con 247 cuestionarios recogidos antes del brote y otros 601 después del mismo. Este estudio incluye una serie de hipótesis puestas a prueba adoptando un diseño de investigación de carácter pseudo-experimental.

Los resultados de este estudio apuntan a que el brote de COVID en China conllevó un incremento en la proporción de los clientes de hoteles propensos a aceptar el uso de robots en este contexto. Después de la pandemia, hubo un incremento en la percepción de la importancia de su utilidad, influencia social, actitud y valor de los robots en este contexto, mientras que descendió la percepción de la importancia de la facilidad del use de robots y antropomorfismo descendió. Como servicio sin necesidad de contacto físico, la utilidad de los robots en hoteles fue más valorada por los clientes Esto produjo una disminución en los requisitos de los usuarios en lo referente a la facilidad del uso de robots en hoteles. Además, los participantes en esta encuesta se mostraron más propensos a valorar la influencia sobre la sociedad del uso de robots.

La actitud de clientes de hoteles y su aceptación del uso de robots en este contexto, así como los servicios que éstos proveen están cambiando rápidamente. No obstante, aún no se sabe con certeza hasta que punto estos cambios son meramente efímeros y motivados por una actitud pragmática hacia la crisis creada por la pandemia del COVID-19.

El sector de la hostelería debería intentar desarrollar un perfil de clientes nuevo en lo referente a su grado de aceptación de los robots como parte de los servicios ofrecidos. Los hoteles deberían considerar el uso de robots en los servicios ofrecidos dependiendo de las características demográficas de sus clientes (ejem. Nivel de estudios y formación).

Este estudio demuestra que las crisis de gran magnitud, como lo es la pandemia actual de COVID-19, pueden afectar las actitudes y comportamientos del consumidor en lo referente al uso de nuevas tecnologías. La pandemia del COVID-19 ha llevado a muchos clientes de hoteles a prestar una mayor atención a las ventajas de los servicios ofrecidos por robots como forma de reducir las posibilidades de contagio.

This paper aims to propose a decision-making framework by investigating the impact of perceived risk and computer self-efficacy on the intention to use online stock trading. Furthermore, it demonstrates the mediation effect of attitude and perceived risk as well as the moderating effect of financial literacy.

An integration of two popular models, technology acceptance model (TAM) and theory of planned behaviour (TPB), is used to provide a sound theoretical base and enhance the understanding of investors’ behaviour towards online trading platforms. The proposed hypothesised model was examined using structural equation modelling.

The results obtained from this study indicate that all variables, except subjective norms, had a significant impact on investors’ intention to trade online. Perceived risk was found to be a partial mediator between computer self-efficacy and the intention of investors. Finally, financial literacy was also found as a significant moderator for online trading intention of investors.

This study shows the significance of using the TAM and TPB together to provide a comprehensive understanding of the factors that influence an investor’s behaviour in adopting and using technology for online trading. The hybrid approach of TAM and TPB could be considered for a more nuanced and complete understanding of technology adoption and usage in risky affairs like investment decisions. Again, the significant moderating role of financial literacy provides a lance to look into the scope for improvements in investment decision-makings.

The paper develops an assessment framework for analysing the variables based on the hybrid approach for online trading intention in the context of a developing country.

Breast cancer has become the largest cancer in the world today. Health problems for women with breast cancer need to be addressed urgently. This study aims to select the best method for preparing temperature-sensitive sports underwear, and to verify the feasibility of using K-type thermocouple threads in underwear fabrics.

In the experiments, two samples were designed for temperature-sensitive performance tests and the effects produced by different outer layer structures were investigated. In the second step, K-type thermocouple wires were integrated into sports underwear. The comfort and feasibility of the temperature-sensitive underwear were investigated.

It was finally verified to obtain the best comfort and temperature-sensing performance of K-type thermocouple filaments integrated into sports underwear with plain stitching.

The underwear has a certain prospect for the application of smart apparel based on breast cancer health monitoring, which is of some significance for monitoring smart apparel.

The aim of this paper is to study the association between health consciousness, health belief model and intention to engage in healthy activities in addition to use restaurants.

An electronic questionnaire was distributed through social media and university website including questions on demographic variables and Likert scaled aspects of health consciousness, health belief model and behavioral intention to practice healthy habits and use fast-food restaurants.

A total of 92 Palestinian adults participated in this study. Age 28.5 ± 9.7 years. Of the studied group, 28.6% were males, body mass index = 24.4 ± 4.1 kg/m². Average health consciousness was 12.3 ± 3.1, health belief model (susceptibility = 10.4 ± 6.8, severity = 12.7 ± 7.2, benefit = 28.1 ± 5.3 and barriers = 17.8 ± 6.8) and for behavioral intention = 21.1 ± 6.4. In final regression models, only benefit was significantly associated with health consciousness (B = 0.18 ± 0.07, p = 0.012) and behavioral intention B = 0.26 ± 0.13, p = 0.05). Only barrier and severity were associated significantly with number of using restaurants weekly (0.04 ± 0.02, p = 0.03) and (0.05 ± 0.02, p = 0.004), respectively.

Health belief model partially explained use of restaurants and healthy lifestyle among Palestinians. This is a cross-sectional design and future clinical trials are needed.

To the best of the authors’ knowledge, this is the first study to address the role of health belief model and health consciousness in improving dietary style and habits.

Being a parent supposes an important number of language interactions with children and other social actors, in order to realize “parental functions”, such as everyday communication with children, transmission of knowledge, expression of emotions, communication with school and others. As for parents with migrant backgrounds, some realize their parenting functions while using only the language of the country of origin, whilst others use only the language of the host country, and some parents use both of these languages. The aim of this paper is to discuss which of these language practices enables parents to more fully realize their parental functions. The paper is based on a thematic analysis of non-directive narrative interviews of parents and children with migrant backgrounds in Strasbourg (France) and Frankfurt-am-Main (Germany). We come to the conclusion that “fuller” or “more partial” realization of parenting functions depends on parents’ subjective perceptions. For instance, in similar language use situations, some parents believed their language practices had allowed them to realize their parenting functions “more fully” while others considered that they had only been able to “partially” do so. This paper opens up a new avenue of reflexion while analysing the concept of “partial parenting” regarding the use of languages by migrant parents. We hope that it will be be of interest to migrant and also non-migrant parents and their children, as well as to researchers and professionals working with immigrant families and that it will contribute to raising awareness about the role of languages in parenting.
