Smart Healthcare Systems Use: A Cross-Cultural Empirical Study Using Valence–Instrumentality– Expectancy Theory, Khaled A. Alshare, Murad Moqbel, Valerie L. Bartelt, Maysoon Sewailem

Information Systems Faculty Publications

In recent years, smart healthcare systems (SHS) spurred by the Internet of things have revolutionized how people manage their health. Despite their numerous benefits, SHS still face many challenges worldwide, including limited user motivation. This study builds on the valence-instrumentality-expectancy theory to examine the motivational factors influencing the use of SHS, while also considering the moderating role of social support. We conducted two studies— one in the United States and the other in Qatar—to assess how well the proposed model applies across different cultural contexts. Our findings show that the model explains users’ motivations to use SHS and the interdependencies …

Helical Coil Compression Spring Retrofit Design Of Wheelbarrow For Optimal Load Carrying Effectiveness, Cornelius Ogbodo Anayo Agbo

Makara Journal of Technology

Wheelbarrows are essential multipurpose and dual-function materials handling equipment for many industries and homes. They find exclusive use in the movement of finished goods and raw materials where no other form of transportation works. However, the traditional wheelbarrows require enormous human effort to accomplish the task of conveying a reasonable amount of load from one place to another. During the process, shock loads from road irregularities are transmitted directly to the Barrow pusher. Therefore, this study investigated a retrofitted helical coil, compression spring, wheelbarrow design for effective load transportation. A wheelbarrow with a trapezoidal bucket capacity of 50 l was …

Makara Journal of Technology

The effects of airflow dynamics, heat transfer, and mechanical properties on the HDPE blown film extrusion process were examined using a single-lip air ring with a fixed compressed-air valve opening angle of 10°. Reynolds numbers ranging from 9175 to 25911 were analyzed to understand their impact on cooling efficiency, bubble morphology, and film properties. Numerical simulations employing the Standard k−ω turbulence model in ANSYS FLUENT v2023, with mesh refinement achieving y+ ≈ 1, captured detailed flow and heat transfer behavior. Results showed that higher Reynolds numbers significantly enhanced the heat transfer coefficient, with values increasing from 1096 W/m²·K at Reynold …

Prediction Of Maximum Local Scour Depth Due To Horizontal Jets Of Flushing Gate Using Artificial Neural Network, Adhy Kurniawan, Muhammad Sulaiman, Agus Maryono, Bambang Agus Kironoto, Amalia Ula Hazhiyah

Makara Journal of Technology

Local scour is a serious concern for hydraulic engineers. To maintain the reservoir capacity, flushing accumulated sediment is necessary, resulting in a turbulent and scouring jet from the flushing gate. Predicting the maximum scour depth from these water jets is crucial for civil engineers. Despite many proposed equations, one have shown consistent applicability due to the complex nature of the process. Ensuring accurate prediction between hydraulic parameters and the geometry of the scour hole in prototype experiments remains a key issue. To address this issue, this paper examines the use of artificial neural network (ANN) analysis as a computing device …

When Delivery Matters: Diffuse Coronary Vasospasm With Continuous, But Not Bolus, 5-Fu Infusion, Muhammad Sabri, Zinya Talukder, Angad Bedi, Sung-Hae Cho

Division of Internal Medicine Faculty Papers & Presentations

5-Fluorouracil (5-FU) is a fluorinated pyrimidine chemotherapy analogue used to treat various gastrointestinal solid malignancy. It is known to be associated with cardiotoxicity. Here, we present a case of 58-year-old male with mucinous adenocarcinoma of the sigmoid colon who experienced global coronary vasospasm in setting of continuous 5-FU infusion refractory to prophylactic antianginal treatment. However, he was asymptotic when given bolus of 5-FU. Our case highlights the difference in toxicity between continuous and bolus 5-FU therapy and emphasizes the need for further research in the pathophysiology and treatment of cardiotoxicity related to 5-FU therapy.

Digital Twinning To Advance Effluent Water Treatment For Pulp And Paper Mills: A Data-Driven Approach For Process Optimization, Fatima Iqbal, Fatemeh Naeijian, Christopher Page, George Fu, Francisco Cubas-Suazo, Stetson Rowles

Civil Engineering & Construction: Faculty Publications

The pulp and paper industry is the third largest freshwater consumer and faces pressure to minimize water usage and environmental impact. Aerated stabilization basins (ASBs) play a crucial role in treating their wastewater, yet existing open-source models often fail to accurately predict treatment efficiency across varying conditions. This study addresses this gap by advancing ASB modeling for ultimate oxygen demand prediction. Specifically, we improved accuracy with variable temperature corrections and incorporating uncertainty to capture the variability in outputs. The models demonstrated strong predictive performance for ultimate oxygen demand (mainly carbonaceous and nitrogenous biochemical oxygen demand) with R2 values ranging from …

The Role Of Fuzzy Logic In Cost-Volume-Profit Analysis, Ahmed Imad Abed Al-Atabe, Mohammed Wafi Abbas Al-Shammar

Muthanna Journal of Administrative and Economics Sciences

Cost-volume-profit analysis (CVP) is one of the most important basic tools in management accounting. It enables understanding the relationship between three key elements: costs, volume, and profit level. The problem with this research is that this type of analysis, in its traditional form, uses clear and fixed data, such as the variable cost per unit, total fixed costs, selling price, or sales volume, which can be accurately determined. However, these assumptions do not accurately reflect practical reality, which is often characterized by uncertainty and fluctuations. The research aims to utilize an artificial intelligence tool, fuzzy logic, as a more flexible …

The Dual Income, No Kids (DINK) lifestyle is gaining popularity in the Philippines as couples prioritize financial freedom and personal development. It is recognized that in the Philippines, where family-centered values hold significant importance, living a childfree lifestyle remains a rare choice. However, this choice has recently gained attention, reflecting a growing tension between traditional expectations and modern aspirations. Lack of literature on Dual Income, No Kids (DINK) families in the Philippines created a gap in understanding this phenomenon and failed to present how Filipino couples navigate this choice. The study employed a transcendental phenomenological (TPh) approach, which involves understanding …

Sinaya: A Philippine Journal for Senior High School Teachers and Students

The Filipino teleserye, known for its social realism, offers insights into its viewers’ lives but often presents limited and stereotyped portrayals of LGBTQI+ individuals, including queer women, due to heteronormativity. Fanfiction, specifically slash fiction, resists this by reimagining heteronormative narratives from a queer angle. Despite digital media advancements, Philippine research has yet to analyze fan-led queer representation on digital storytelling platforms, such as TikTok. Hence, following similar research by McGorry (2022), this study purposively sampled fifty sapphic TikTok fan edits of the teleserye Darna (2022) to examine how Vadengs, fans of protagonists Narda Custodio (Darna) and Regina Vanguardia (Valentina), reimagined …

Accessible healthcare remains a challenge for rural communities lacking reliable infrastructure for medical supply delivery. Delivery drones have recently emerged as a viable alternative, dropping medical containers during flight. However, the effectiveness of different foam types and thicknesses combined with corrugated cardboard as shock-absorbing materials in a medical container for delivery drones has yet to be tested. Thus, this study designed cost-effective containers using corrugated cardboard and multiple foam types and thicknesses, aiming to preserve the integrity of the contents, withstand impact, and control temperatures. Four foam types—polystyrene, polyurethane, polyethylene, and expanded polystyrene (EPS) —were tested at 1 cm, 2 …
