https://humentech.utm.my/index.php/humentech/article/view/64
<p>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.</p>Wai Keng Mike ChoongMaizatul Hayati Mohamad YatimNoorhayati Saad

https://humentech.utm.my/index.php/humentech/article/view/63
<p>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.</p>Nik Ahmad Nizam Nik MalekCorrienna Abdul TalibNur Shafina Mohd NorIbrohimJuan MatminSiew Ling LeePraseetha PrabhakaranNor Suriani SaniMuhammad Khair Noordin

https://humentech.utm.my/index.php/humentech/article/view/73
<p>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.</p>Jahanzeb SheikhDr. Syafiqah SaidinSameen Ahmed MalikTian Swee TanLee Suan ChuaAsim Ahmed Ibrahim Mohamed AhmedMa KunMatthias Foh Thye Tiong Kah Meng Leong

https://humentech.utm.my/index.php/humentech/article/view/69
<p>In response to the coronavirus disease 2019 (COVID-19) pandemic, the shift to online delivery mode for most teaching faculties has increased the risk of chronic back and neck pain for students and teachers. While short-term adjustments like working from the couch or using an uncomfortable kitchen chair might seem tolerable for working adults or university students, these habits can have detrimental long-term impacts on body and health. Although the pandemic situation has improved, and people are gradually returning to physical workplaces and classrooms, many individuals still spend a significant amount of time sitting in front of screens for work and other activities. This explains why 70% of adults in Malaysia have experienced back and neck pain at least once in their lives. This pre-study proposes a smart chair equipped with sensors that alert users to correct their sitting posture and take screen breaks for stretching, potentially reducing the risk of future muscle aches and pain.</p>Muhammad Norman Nurhakim Mohd ShahrimanXi Ning TanMahmud Thaqif Mahmud RasidBatrisyia Inanda Sari YusriNurul Ashikin Abdul-KadirNorlaili Mat Safri

https://humentech.utm.my/index.php/humentech/article/view/66
<p>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.</p>Naufal Fikri MuhammadRaimi DewanJaysuman PusppanathanFaishal Adilah Suryanata
