Monitoring women’s health during the menstrual cycle is crucial. Traditional methods for estimating ovulation dates involve measuring body temperature and analyzing blood, urine, cervical mucus, or saliva. While effective, these methods come with various advantages and limitations. Therefore, we introduce a novel approach to more easily and accurately detect both the menstrual period and the ovulation date. After gathering essential physiological data from test subjects, the ovulation date is predicted. Heart rate waveform signals are used to identify physiological parameters linked to ovulation, enhancing prediction accuracy without relying on consumable items such as test strips or patches. By integrating non-invasive image signal processing technology and heart rate variability analysis algorithms, the timing of ovulation within the menstrual cycle is accurately predicted.

Stock market forecasting has always been researched extensively in Social Sciences. In this research, Fuzzy time series with deep learning is widely adopted to create a fuzzy convolutional neural network integration model as this model enhances the fuzzification of values to enhance feature characteristics using two-dimensional input data in convolutional neural networks (CNNs). This allows the model to retain complete feature information. The fuzzy convolutional neural network (FCNN) model autonomously learns and extracts crucial features by integrating stock market data, resulting in improved forecasting accuracy. In this study, the model was tested for forecasting the Taiwan Weighted Stock Index and metrics such as the mean squared error (MSE) and mean absolute error (MAE), and the results were compared with the real data. The results showed that the model provided accurate predictions. Full article

In modern communication technology, short videos are increasingly used on social media platforms. The advancement of video codecs is pivotal in communication. In this study, we developed a new scheme to encode the residue of intraframes. For the H.264 baseline profile, we used context-based arithmetic variable-length coding (CAVLC) to encode the residue of integer transforms in a block-wise manner. In the developed method, the DC and AC coefficients are separated. In addition, context assignment, adaptive scanning, range increment, and mutual learning are adopted in a mixture of fixed-length and variable-length schemes, and block-wise compressions of the frequency table are applied to obtain improved compression rates. Compressing the frequency prevents CAVLC from being hindered by horizontally/vertically dominated blocks. The developed method outperforms CAVLC, with average reductions of 7.81, 8.58, and 7.88% in quarter common intermediate format (QCIF), common intermediate format (CIF), and full high-definition (FHD) inputs.

A simple urine phantom was developed to replicate the ultraviolet–visible (UV–Vis) spectrum of healthy human urine. Made from four safe and widely available ingredients, it addresses the challenges of biological samples, including safety risks and storage issues. The spectroscopic analysis results confirmed strong similarity to natural urine, making the phantom appropriate for testing spectroscopic methods, calibrating optical devices, and evaluating diagnostic sensors. It can also serve as a starting point for advanced phantoms tailored to specific patient needs or diseases. This reliable alternative facilitates research in optical diagnostics or biosensor development by simplifying preliminary sensor testing. Full article

By employing the analytic hierarchy process (AHP), we investigated consumer demand and preferences for InsurTech technologies. A survey was conducted with 350 respondents, yielding 348 completed questionnaires and achieving a response rate of 99.4%. After consistency checks, 78 invalid questionnaires were excluded, resulting in 270 valid responses, with an effective response rate of 77.3%. Using the Analytic Hierarchy Process (AHP), five critical dimensions were identified as top priorities for insurance companies implementing InsurTech solutions: (1) video insurance and mobile applications, (2) blockchain-based claims processing, (3) robo-advisors, (4) the Internet of Things (IoT), and (5) big data analytics. Video and mobile applications, along with blockchain, accounted for over 30% of the total importance of evaluating InsurTech technologies. Among the assessment criteria, “mobile applications” and “remote insurance” had the highest weights, highlighting their roles in the InsurTech service model. Insurance providers need to prioritize these two dimensions when designing their InsurTech service models to enhance service convenience and the customer experience. Full article

Food loss and waste are critical challenges in Taiwan’s agri-food supply chain, deteriorating security and resource efficiency. By employing the best–worst method (BWM), a multi-criteria decision-making model was developed in this study to evaluate the severity of losses and wastes. Combining literature review results with expert survey analysis results, key loss points, and mitigation strategies were identified to enhance sustainability and efficiency in Taiwan’s agricultural food system. Among the seven stages of the agricultural food supply chain, supermarket waste (16.95%) was identified as the severest, followed by government policies (16.63%), restaurant waste (15.35%), processing loss (14.71%), production site loss (13.64%), household waste (11.93%), and logistics/storage/distribution loss (10.79%). In the subcategories of each supply chain stage, the eight severe issues were identified as “Inadequate planning and control of overall production and marketing policies” under government policies, “Adverse climate conditions” and “Imbalance in production and marketing” under production site loss, “Inaccurate market demand forecasting” and “Poor inventory management at supermarkets” under supermarket waste, and “Improper storage management of ingredients leading to spoilage” as well as “Inability to accurately forecast demand due to menu diversity” under restaurant waste. The least severe issues included “Poor production techniques” under production site loss. Other minor issues included “Inefficient use of ingredients due to poor cooking skills”, “Festive culture and traditional customs”, and “Suboptimal food labeling design”, all of which contributed to household waste. Based on these findings, we proposed recommendations to mitigate food loss and waste in Taiwan’s agricultural food supply chain from practical, policy, and academic perspectives. The results of this study serve as a reference for relevant organizations and stakeholders. Full article

In traditional programming education, teachers typically design fixed questions and standard answers, manually grading the solutions submitted by students. This process not only requires significant time and effort from educators but may also fail to provide timely and personalized feedback due to limited teaching resources. To alleviate these burdens and enhance teaching efficiency, this study leverages generative artificial intelligence (AI) technology to develop a system capable of automatically generating questions and grading answers. Students engage in programming exercises through a gamified approach, with the system providing instant feedback on their answers. Additionally, student performance is displayed via leaderboards, incorporating peer competition to boost learning motivation. According to a user survey, the gamified system demonstrates significant advantages: 56.67% of students found the system easy to use; 40% considered the system well-integrated; 60% indicated that they quickly mastered the system’s functionality, and over half (53.33%) believed that the leaderboard effectively enhanced their competitive awareness and motivation. These results suggest that the system not only reduces teachers’ workload but also increases student engagement and learning outcomes through gamified design. Full article

In the development of the city, land planning must be precise and collective, emphasizing the multi-functional usability of space. The space under bridges can be utilized for urban development. However, the space under bridges has been researched only based on the theoretical operation of space, and the psychological values of the attributes of the space under bridges held by users have been rarely studied. Therefore, we explored the attributes of the space under bridges using the critical chain method and interviews with the stakeholders. The characteristic attributes were identified with regional implications. The attributes need to be considered in the spatial planning to enhance the space utilization under bridges. The results of this study present important information for policymakers or designers to plan the use of space. Full article

We investigated the configurational conditions influencing primary and secondary school teachers’ behavioral intentions (BIs) and usage behavior (UB) in adopting digital learning tools by using fuzzy set qualitative comparative analysis (fsQCA) and Tobit analysis. Based on the extended unified theory of acceptance and use of technology (UTAUT2) and by integrating TPK, configurations that drive or hinder teachers’ use of digital tools were identified. The results revealed that BI formation is driven by the core combination of facilitating conditions (FC) and hedonic motivation (HM); the synergy of FC, HM, and TPK; and the interplay of TPK and HM. UB was significantly promoted by the combinations of H with BI and TPK with BI. Conversely, the low levels of H and BI, or H and TPK lowered the levels of UB. By integrating fsQCA and Tobit analysis, the complex and asymmetric effects in digital tool adoption were understood, and recommendations were proposed to develop differentiated support strategies based on these configurational findings.

Dexterity of the fingers is crucial in physical function, as it directly impacts daily activities and is closely connected to cognitive function. The production of brain-derived neurotrophic factor (BDNF) is related to the fingertips in motion. In previous research, we developed a finger motion measurement system for the elderly by integrating image recognition technology with a touch panel. However, despite the system’s ability to capture fine-grained coordinate changes at the moment when fingers touch the panel, the experiment was unengaging for participants. Therefore, we improved the system for measuring finger motion to be less exhausting and more enjoyable. We incorporated music and gamification elements at the moments of finger touch. We obtained a selection of representative rhythm tracks and implemented animated materials in gamification. The participants’ fatigue and enjoyment were measured based on “responsiveness” and “focus” using a quantitative evaluation method. Full article

This article presents the concept and principles of digital technology for community development and community developers. An approach for creating no-code mobile applications for community developers’ fieldwork surveys is also proposed to organize a digital technology skill training program focused on no-code mobile application development for community developers. The training program consists of a two-day hands-on workshop in no-code mobile application development with 50 community developers participating in its development. A 70% increase in participants’ knowledge of utilizing digital technology for local community development was observed, with all participants (100%) successfully developing no-code mobile applications for surveying data on their communities. Additionally, the participants expressed high satisfaction with the training format and content, with an average score of 4.80. Digital technology knowledge is essential for contemporary community development efforts. Empowering community developers, especially those engaged in fieldwork, to independently acquire mobile app development skills or access continuous learning resources significantly enhances their professional capacity. This empowerment leads to more effective and efficient community development practices, particularly in community data collection. Full article

We developed an evaluation index model for healing gardens designed using computer-aided design. The landscape therapy theory, innovative methodologies such as the fuzzy Delphi method, and the analytic hierarchy process (AHP) were integrated into the model. Three core design indices for healing gardens—somatosensory elements, visual components, and physical activity features—were identified and analyzed using the developed index model in this study. Plant diversity was identified as the most significant factor, followed by modeling aesthetics, color variety, plant healing properties, spatial recreational features, sensory richness, unobstructed circulation, and barrier-free design. While the developed evaluation index model has limitations, it is a novel and systematic model based on innovative computing methods to assess and enhance contemporary healing garden design.

In this study, a service quality (SQ) quantitative assessment method for retail industry operations was established to transform the perceptions and expectations of consumers into measurement framework requirements in the Indian market. The benefit of the recently created framework using interval-valued Pythagorean fuzzy to analyze the SQ is to handle imprecise human assessments, which is lacking in traditional SQ assessment methods. Therefore, we proposed a two-stage SQ assessment method by applying an extended novel Fuzzy methodology. We conducted a systematic literature review to identify the service quality and its products in the framework of the retail industry. In addition, we identified the gaps and proposed the measurement framework through consumer expectations and perceptions gaps. The present research findings confirmed that reliability and tangibility are important SQ dimensions reflecting the customer’s opinions. The findings help retail businesses make collective decisions on high-priority areas and effectively allocate resources to meet the needs of their customers. Full article

In Vietnam, English proficiency is a graduation requirement and offers students great opportunities to win scholarships and employability after graduation. Universities in the Mekong Delta region (MDR) often face challenges in foresting students’ English proficiency despite continuous assistance offered. Although students have taken online supplementary courses (OSC) delivered through e-learning systems to support their English formal classes for several years, students’ successes in English tests with such supplementary courses and the predictors of this issue remain unknown. Therefore, we developed a model to predict students’ success in English final tests based on behaviors and grades in OSC using logistic regression (LR) and classification and regression tree (CART) classifiers. A total of 109 students of OSC in a target university in MDR participated in this study, and the result showed that CART (area under the curve (AUC) = 89.3%) was slightly better than LR. The outcomes of this study contribute to students’ success in English tests and the enhancement of the effectiveness of online supplementary courses for English improvements. Full article

Fluid effects are important in films and advertisements, where their realism and aesthetic quality directly impact the visual experience. With the rapid advancement of digital technology and computer-aided design (CAD), modern visual effects are used to simulate various water-related phenomena, such as flowing water, ocean waves, and raindrops. However, creating these realistic effects is not solely dependent on advanced software and hardware; it also requires an understanding of the technical and artistic aspects of visual effects artists. In the creation process, the artist must possess a keen aesthetic sense and innovative thinking to craft stunning visual effects to overcome technological constraints. Whether depicting the grandeur of turbulent ocean scenes or the romance of gentle rain, the artist needs to transform fluid effects into expressive visual language to enhance emotional impact, aligning with the storyline and the director’s vision. The production process of fluid effects typically involves the following critical steps. First, the visual effects artist utilizes CAD-based tools, particle systems, or fluid simulation software to model the dynamic behavior of water. This process demands a solid foundation in physics and the ability to adjust parameters flexibly according to the specific needs of the scene, ensuring that the fluid motion appears natural and smooth. Next, in the rendering stage, the simulated fluid is transformed into realistic imagery, requiring significant computational power and precise handling of lighting effects. Finally, in the compositing stage, the fluid effects are seamlessly integrated with live-action footage, making the visual effects appear as though they are parts of the actual scene. In this study, the technical details of creating fluid effects using free software such as Blender were explored. How advanced CAD tools are utilized to achieve complex water effects was also elucidated. Additionally, case studies were conducted to illustrate the creative processes involved in visual effects production to understand how to seamlessly blend technology with artistry to create unforgettable visual spectacles.

This study aims to predict and discover important factors for the learning performance of students belonging to two ethnic groups—Khmer and Chinese (Hoa) students—in Soc Trang with the use of random forest (RF) and Gaussian Naïve Bayes (GNB) classifiers based on students’ demographics and grade point average (GPA) scores. The study involved 174 Khmer and Chinese (Hoa) students in Grade 10 in a high school in Soc Trang Province, Vietnam. The results showed that, for Khmer students, GNB was better than RF, with an F1 score of 100%. Mathematics was the most important subject leading Khmer students to very good or poor performance. For Chinese (Hoa) students, both classifiers showed the same accuracy performance. Scores in Literature and English in Semester 1 impacted Chinese (Hoa) students’ performance. The results of this study provide a reference for formulating a policy to improve the learning performance of minority students to prevent dropouts. Full article

We examined the effects of cooperative learning on learning satisfaction and learning effectiveness of elementary school students on the Quizlet online platform using an experimental design approach. Third and fourth-grade students from an elementary school in Taichung City were recruited in this study. A total of 55 students participated in this study and were grouped into the experimental group (28) and the control group (27). The experimental group engaged in game-based cooperative learning activities, while the control group participated in individual learning sessions. After eight weeks of the intervention in which one 30 min session was conducted every week, data on learning satisfaction and learning effectiveness were collected using a questionnaire. The collected data were analyzed to obtain descriptive statistics, independent sample t-tests, Pearson correlation analysis, and regression analysis. The participants in the experimental group reported improved learning satisfaction, learning environments, learning outcomes, and peer interactions compared with the control group. The experimental group also scored higher in learning effectiveness including skills. Significant differences were observed in learning satisfaction and effectiveness across genders and grade levels. A strong positive correlation indicated that higher learning satisfaction improved learning effectiveness among elementary students. Learning satisfaction was a significant predictor of learning effectiveness, highlighting the importance of cooperative learning for better learning outcomes. The results of this study provide a reference for elementary English teachers to incorporate online platforms in their teaching practices. Full article
