Mathematics is an important foundation for the development of science education. In the past, when instructors taught mathematical concepts of geometry shapes, they usually used traditional textbooks and aids to conduct teaching activities, which resulted in students not being able to understand the principles completely. Nowadays, it has become a trend to integrate emerging technologies into mathematics courses and to use digital instructional aids. Emerging technologies can effectively enhance students’ sensory experience while strengthening their impressions and understandings of subject concepts. (...) In this paper, we apply virtual reality immersive technologies to develop a “virtual reality immersive learning mathematics geometry system,” which is used to teach mathematical geometry concepts. Teachers use the system to develop three basic mathematical geometry learning materials: “Triangular pyramid volume = 1/3 prism volume,” “Cone volume calculation,” and “Triangle center of gravity derivation.” In the experimental activity, the teacher uses virtual reality teaching aids to guide students to learn mathematical geometry concepts in a fun way so that they can achieve the effectiveness of immersive learning. This study explores the impact of using the virtual reality immersive learning mathematics geometry system on students’ technology acceptance, learning motivations, and learning performance. The experimental result showed that using the virtual reality immersive learning mathematics geometry system can improve the learning motivation and learning performance of students. The findings indicated that the experimental group had better learning outcomes after completing the learning tasks of three geometric units. The experimental group used the virtual reality immersive learning mathematics geometry system which can lead to better learning outcomes. According to the ARCS questionnaire, students in the experimental group were confident to understand new subjects. At the same time, the mode of completing the game can effectively give students a sense of accomplishment. The use of emerging technologies in the classroom can be an attractive learning mode for students. (shrink)

The purpose of this study was to develop and empirically test a model for predicting the key factors affecting nurses’ behavioral intention to use mobile learning. We explored behavioral intention from users’ perspectives by applying an extended unified theory of acceptance and use of technology model with the addition of information quality, system quality, technostress, and satisfaction. We conducted a survey of the district and regional hospitals in central Taiwan. Data were derived from 434 respondents. Structural equation modeling was applied (...) to analyze the causal effects of 15 hypothesized predictive factors. We determined that satisfaction, social influence, performance expectancy, facilitating conditions, and effort expectancy positively impacted nurses’ behavioral intention to use m-learning. In addition, technostress was a negative antecedent of effort expectancy. Information quality and system quality had significantly positive effects on satisfaction, performance expectancy, and effort expectancy. This study provides hospital managers with a reference when assessing future developments and informs approaches to promote m-learning. (shrink)

Previous studies have shown that the motion intention recognition for lower limb prosthesis mainly focused on the identification of performed gait. However, the bionic prosthesis needs to know the next movement at the beginning of a new gait, especially in complex operation environments. In this paper, an upcoming locomotion prediction scheme via multilevel classifier fusion was proposed for the complex operation. At first, two motion states, including steady state and transient state, were defined. Steady-state recognition was backtracking of a completed (...) gait, which would be used as prior knowledge of motion prediction. In steady-state recognition, surface electromyographic and inertial sensors were fused to improve recognition accuracy; five typical locomotion modes were recognized by random forest classifier with over 97.8% accuracy. The transient state was defined as an observation period at the initial stage of upcoming movement, in which only the sEMG signal was recorded due to the limitation of sliding window length. LightGBM classifier was validated to outperform other methods in the accuracy and prediction time of transient-state recognition. Finally, a simplified HMM model based on prior knowledge and observation result was constructed to predict upcoming locomotion. The results indicated that the locomotion prediction was over 91% accuracy. The proposed scheme implements the locomotion prediction at the initial stage of each gait and provides critical information for the gait control of lower limb prosthesis. (shrink)

AimOur study aimed to investigate the effect of social responsibility on the subjective well-being of volunteers for COVID-19 and to examine the mediating role of job involvement in this relationship.BackgroundNowadays, more and more people join volunteer service activities. As we all know, volunteer work contributes to society without any return. Volunteers often have a strong sense of social responsibility and reap subjective well-being in their dedication. Although research shows that social responsibility will drive them to participate in volunteer work actively, (...) it is less clear whether job involvement will impact their subjective well-being.MethodsThe data were collected in the precaution zone in Shanghai, China, from April to May 2022. A sample of 302 volunteers for COVID-19 completed the social responsibility scale, subjective well-being scale and job involvement scale in the form of an electronic questionnaire on their mobile phones. A structural equation model was adopted to verify the research hypotheses.ResultsSocial responsibility was significantly and positively related to volunteers’ subjective well-being and job involvement. Job involvement fully mediates the relationship between volunteers’ social responsibility and subjective well-being.ConclusionSocial responsibility is critical to predicting volunteers’ subjective well-being. Job involvement plays an intervening mechanism in explaining how social responsibility promotes volunteers’ subjective well-being. (shrink)

One of the problems religious men and philosophers often face is how to convey enlightenment or wisdom to others so that sentient beings can be enlightened or awakened from dogmatic views. This problem is also the question of how truth is made known to men. The purpose of this paper is to investigate the problem of communicating truth in Ch'an Buddhism.

A fuzzy predictive fault-tolerant control scheme is proposed for a wide class of discrete-time nonlinear systems with uncertainties, interval time-varying delays, and partial actuator failures as well as unknown disturbances, in which the main opinions focus on the relevant theory of FPFTC based on Takagi-Sugeno fuzzy model description of these systems. The T-S fuzzy model represents the discrete-time nonlinear system in the form of the discrete uncertain time-varying delay state space, which is firstly constructed by a set of local linear (...) models and the nonlinear membership functions. The novel improved state space model can be further obtained by extending the output tracking error to the constructed model. Then the fuzzy predictive fault-tolerant control law based on this extended model is designed, which can increase more control degrees of freedom. Utilizing Lyapunov-Krasovskill theory, less conservative delay-range-dependent stable conditions in terms of linear matrix inequality constraints are given to ensure the asymptotically robust stability of closed-loop system. Meanwhile, the optimized cost function and H-infinity performance index are introduced to the stable conditions to guarantee the robust performance and antidisturbance capability. The simulation results on the temperature control of a strong nonlinear continuous stirred tank reactor show that the proposed control scheme is feasible and effective. (shrink)

The book entitled the Huang Ti nei ching [Canonical Works of Huang Ti] has two sections - the "Su Wen" section and the "Ling Shu" section - and each section contains eighty-one articles. It was written by several authors in different historical periods. According to historical records and scholars' studies of the content and context of the book, we can roughly say that it was written in the period between the late years of the Warring States era and the early (...) years of the Eastern Han dynasty. Seven articles in the "Su Wen" section were materials from an "older version" and were merged into the book by Wang Fing in the Tang dynasty. They were probably written by scholars in the Eastern Han period or a little later. The two articles on acupuncture and pathology have been proved forgeries made in the Tang-Sung period. They should not have been included in the book because they contain more idealist dregs than do the other articles. (shrink)

AimsA negative association between the lower level of psychological resilience and increased risk of compassion fatigue and higher Coronavirus disease 2019 stress has been revealed. However, bibliometric studies have not been performed to comprehensively investigate this topic. This study aimed to identify the status and trends in the CF and PR field from 2008 to 2021 and during the COVID-19 pandemic.MethodsWe identified relevant literature from the Web of Science Core Collection® database using “resilience” and “compassion fatigue” on September 30, 2021. (...) All search results were exported in plain text format for collaboration network analysis, reference-based co-citation analysis, analysis of journals, and keywords-based co-occurrence analysis, which were performed using Citespace® 5.8.R1.ResultsA total of 388 publications were identified finally, and there has been an increasing trend in the annual number of publications with light fluctuations. The analysis of journals and keywords indicated that nurses and social workers are the main research targets, and their mental problems are the main research topics. The turnover intention of health care providers has been a research focus, particularly during the COVID-19.ConclusionThe results of the present study help us understand the status of the CF and PR field and its recent developments.

This paper analyzes the ‘Theory of Inverse Numbers’ that appears in Chapter 3 of the “Shuogua zhuan” 說卦傳 in the I Ching and seeks to apply the findings to the Yi studies of Cheng Yi. The Yi studies of Shao Yong, Zhu Xi, and Cheng Yi are generally explained in the categories of Xiangshu(Image-Number) Yi studies and Yili(Meaning-Principle) Yi studies. However, upon analyzing the ‘Theory of Inverse Numbers’ as a theory representing numbers of principles, it is evident that (...) the framework of this theory is also reflected in Cheng Yi’s Yi studies. The analysis of the ‘Theory of Inverse Numbers’ was conducted through the interpretations of Shao Yong and Zhu Xi, proposing the concept of the ‘Theory of Inverse Numbers’ as a Yi interpretation framework that accounts for what has already occurred [yisheng 已生] and what has not yet occurred [weisheng 未生]. By applying the Yi interpretation framework of what has arisen and what has not, which was developed through the explanations of Shao Yong and Zhu Xi, to Cheng Yi’s Yi studies, it is revealed that even though Cheng Yi does not directly mention Chapter 3 of the “Shuogua zhuan,” the narrative framework of Yichuan Yizhuan 伊川易傳 can be well elucidated by the ‘Theory of Inverse Numbers.’ Accordingly, it suggests that viewing Cheng Yi’s Yi studies merely as a dichotomy of meaning-principle and image-number is limited, and that the concept of Xiangshu Yi is inherent in Cheng Yi’s Yi studies. In other words, the ‘Theory of Inverse Numbers’ as a theory of principle-representing numbers originating from Shao Yong is inherent throughout Cheng Yi’s interpretation of the I Ching as a framework of Yi interpretation for what has arisen and what has not, and this was systematized as the ‘Theory of Inverse Numbers’ by Zhu Xi.

Actualmente, la reflexión sobre la imagen se centra mayoritariamente sobre su masiva presencia y su interminable reproducción. En este trabajo nos centraremos, a la inversa, en cómo las imágenes se destruyen masiva y sistemáticamente. Si el examen interdisciplinar es una prerrogativa fundamental en los estudios visuales, el volumen Striking Images, Iconoclasms Past and Present (Ashgate 2013), compilado por excelentes históricos y arqueólogos, ofrece a los filósofos un modelo importante de colaboración a la hora de pensar qué son las imágenes. El (...) propósito de este trabajo es presentar y discutir brevemente algunos aspectos originales de estos ensayos, enfatizando la importancia de los distintos modos y motivos por los que nuestros antepasados no solo han creado, sino también han destruido imágenes. Distinguiendo la iconoclasia del simple vandalismo, podemos descubrir una ambigüedad fundamental según la cual quien intenta preservar las imágenes, acaba con destruirlas y quien aparece como destros antepasados no solo han tructor, logra fertilizar nuevas concepciones y significados para su propia tradición figurativa. Quizás esta ambigüedad no sea algo que las imágenes sufren desde fuera, sino que sea algo connatural a la imagen misma. Y si es así, quien hoy estudia la vida de las imágenes, quizás podría encontrar un acceso privilegiado en esa a través una lógica paradójica que destaca como las imágenes mueren. PALABRAS CLAVESICONOCLASIA, ICONOFÍLIA, FILOSOFÍA Y TEORÍA DE LAS IMÁGENES, ESTUDIOS VISUALES.ABSTRACTContemporary thought on images focuses mostly on their massive presence and their endless reproduction. On the contrary, in this paper, I will focus on how images have been massively and systematically destroyed. If the interdisciplinary exam is a fundamental prerogative in visual studies, the volume Striking Images, Iconoclasms Past and Present (Ashgate 2013), compiled by excellent historians and archaeologists, could offer to philosophers an important frame of teamwork in thinking what the images are. The purpose of this paper is to present and discuss briefly some original aspects of these essays, by emphasizing the importance of means and reasons through which our ancestors have not only created, but also destroyed images. Once distinguished iconoclasm and mere vandalism, we could discover a fundamental ambiguity whereby any person who tries to preserve the images, finishes with wrecking them; while on the contrary somebody who appears as a destroyer, succeeds to fertilize new concepts and meanings for his/her own figurative tradition. Perhaps this ambiguity is not something that image suffers extrinsically, but something inherent to the image itself. And if it is so, he/she who wants to study the life of images, could perhaps find a privileged access to it, through a paradoxical logic that explains, instead, how images die.KEYWORDSICONOCLASM, ICONOPHILIA, PHILOSOPHY AND THEORY OF IMAGES, VISUAL STUDIES.
