Contamination in healthcare environment poses risk of microbial transmission to healthy people. Recently, conventional ultraviolet (UV) technologies, particularly low-pressure mercury lamps have caught researcher’s attention for disinfection. Nonetheless, drawbacks such as hazardous components, limited lifespan, warm-up time, maintenance and fragility have driven researchers to delve into light emitting diode (LED) technologies as an appealing alternative. However, due to the diminishing intensity exhibited by LEDs over extended distances, prior studies primarily focused on short-distance investigations. Consequently, the phenomenon remained insufficient owing to the limited exploration in this field. Furthermore, frequently investigated LEDs in ambient settings, potentially created a gap in completely understanding the capability for irradiance attainability. Hence, this study aimed to overcome this limitation by evaluating the effectiveness of UV-C LEDs with synergistic arrangements within an enclosed chamber, offering optimum settings for examining irradiance performance. The analyzed recorded data aimed to identify trends in emission performance over different distances (5 to 60 cm), providing insights into how the arrangement of LEDs could influence irradiance output. The study unveiled that the synergistic effects of 6, 8, and 10-LED, when strategically engineered, significantly contributed to enhanced intensity. Notably, 10-SEMW LEDs exhibited a remarkable ability to maintain significant irradiance levels across extended distances. This was evident in the range between 0.037 and 0.016 mW.cm⁻² observed at 5 and 60 cm, respectively. In conclusion, the findings stress the importance of strategically arranging LEDs in a synergistic configuration to achieve optimal irradiance levels across a diverse range of spatial parameters for effective long-range disinfection.
医疗环境的污染有可能将微生物传染给健康人。最近，传统的紫外线（UV）技术，尤其是低压汞灯在消毒方面引起了研究人员的注意。然而，有害部件、有限的使用寿命、预热时间、维护和脆弱性等缺点促使研究人员开始研究发光二极管（LED）技术，将其作为一种有吸引力的替代技术。然而，由于发光二极管在较远距离上表现出的强度递减，先前的研究主要集中在短距离调查上。因此，由于该领域的探索有限，这一现象仍然不够充分。此外，经常在环境中对 LED 进行调查，有可能导致对辐照度可实现性的全面了解出现空白。因此，本研究旨在克服这一局限性，通过评估在封闭室中协同排列的 UV-C LED 的有效性，为检查辐照度性能提供最佳设置。分析记录的数据旨在确定不同距离（5 至 60 厘米）的发射性能趋势，从而深入了解 LED 的排列如何影响辐照度输出。研究结果表明，6、8 和 10 颗 LED 的协同效应，经过策略性设计后，可显著增强辐照度。值得注意的是，10-SEMW LED 显示出了在较长距离内保持显著辐照度水平的卓越能力。在 5 厘米和 60 厘米处观察到的辐照度范围分别为 0.037 和 0.016 mW.cm-²。总之，研究结果强调了战略性地将 LED 排列成协同配置的重要性，以便在不同的空间参数范围内达到最佳辐照度水平，从而实现有效的远距离消毒。

Nanomedicine, an emerging field at the intersection of nanotechnology and medicine, holds great promise for revolutionizing healthcare by enabling targeted diagnostics and treatments at the molecular level. However, due to its complex nature, understanding nanomedicine concepts and applications can be challenging for healthcare professionals, researchers, and the general public. To bridge this knowledge gap and promote awareness, a mobile application was developed to enhance the understanding of nanomedicine, and named it "MyNanoRia". The MyNanoRia was developed by initially designing suitable content, compiling information and creating the apps using Unity platform, specifically for the Android operating system. The MyNanoRia provides users with readily available knowledge about nanomedicine's concepts, methods, and applications as an interactive educational tool. Specific facets of nanotechnology, nanomedicine, nanomaterials, and cancer are covered in this app. MyNanoRia also includes definitions for particular keywords. This app's creation required consulting and validation by subject-matter specialists, such as chemists, biologists, and medical scientists. The development of MyNanoRia is challenging since nanotechnology is a multidiscipline topic that indeed emphasizes scientific understanding, but the intended users are those who know little to nothing about it. Creating the MyNanoRia app for understanding nanomedicine seeks to close the knowledge and awareness gap between science and the general public, enabling researchers, healthcare professionals, and the general public to fully value nanotechnology's potential in healthcare.

Crying is a crucial means of communication for newborns, crying is a newborn's early form of communication. Many individuals are unable to recognise a baby's intention from cry unless they have the appropriate training or expertise, such as nurses, paediatricians, and childcare professionals. Accurately interpreting a baby's cry can be challenging. In this research paper, the study uses a method for classifying baby crying sounds using a Convolutional Neural Network (CNN) and the dataset includes belly pain, burping, discomfort, hungry, and tired for total of 3,495 one-second-long audio clips. The research methodology involves preprocessing the audio data, extracting Mel-Frequency Cepstral Coefficients (MFCC) as features, and training the CNN model. To determine the optimal architecture, two different configurations of the CNN model are evaluated. The settings for both configurations are the same, except for the layers. The first configuration utilizes 100, 200, and 100 neurons for the respective layers, while the second configuration employs 256, 512, and 256 neurons for each layer. the results have already been evaluated that the second configuration, with deeper and more complex layers, achieves higher accuracy (86%) compared to the first configuration (84%). The study demonstrates the effectiveness of CNNs in classifying baby cries and highlights the importance of model architecture in achieving accurate classification results. Future research could explore larger and more diverse datasets to improve generalizability.

The first configuration utilizes 100, 200, and 100 neurons for the respective layers, while the second configuration employs 256, 512, and 256 neurons for each layer. the results have already been evaluated that the second configuration, with deeper and more complex layers, achieves higher accuracy (86%) compared to the first configuration (84%). The study demonstrates the effectiveness of CNNs in classifying baby cries and highlights the importance of model architecture in achieving accurate classification results. Future research could explore larger and more diverse datasets to improve generalizability.","PeriodicalId":168265,"journal":{"name":"Journal of Human Centered Technology","volume":"10 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139861878","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}

Higher education academics are lacking the knowledge on how to implement Design Thinking (DT) for transdisciplinary design studies that would produce Fourth Industrial Revolution Workforce Skills (4IRSkills), due to the sparsity in literature and implementation guidelines. This article discusses on the creation process of a Teaching and Learning Framework (TLF) for transdisciplinary design studies with a desktop-based Virtual Reality Learning Environment (VRLE) simulation of studio-based learning. The framework was created using a Selander’s Learning Design Sequence (LDS) with DT approach. The LDS helped the researcher to understand the processes of teaching and learning, especially on the affordances of various modes. The DT approach was used to facilitate the process of solving problems through the practice of empathy, reframing, prototyping, experimentation, testing, and redesign. A sequential explanatory mixed method was used, and the data were analyzed through inferential statistical analysis, thematic analysis and convergent coding matrix triangulation protocol. The findings indicated that the TLF with VRLE showed a positive and significant relationship with students' achievement of 4IRSkills. The TLF Design Process and Collaborative Design variables were positively correlated with students' 4IRSkills, while there was no correlation for the VRLE Representational Fidelity and Learner Interaction variables. In conclusion, the TLF with VRLE proves to be an effective and suitable method for guiding the implementation of pedagogies that teaches 4IRSkills at the tertiary level in fully online learning environments.
