Interactive Mechanism Of Food Packaging Design And Children's Health Consciousness, Yang Qian

Food and Machinery

Food packaging can establish an “entertainment–knowledge–action” interactive closed-loop mechanism for children, effectively guiding them to practice healthy behaviors, overcoming the low efficiency of conventional text- and image-based instruction, and continuously strengthening their health awareness. At present, interactive design for cultivating children’s health awareness through food packaging is constrained by superficial forms of interaction, insufficient integration of entertainment functions, fragmented system construction, and the absence of educational mechanisms in the implementation stage. The “entertainment–knowledge–action” closed-loop design can specifically address the limitations of traditional packaging, including fragmented interaction, superficial cognition, and weak behavioral guidance. Specifically, entertainment serves as the entry point by …

Consumer Judgment, Choice, And Meaning-Making In Food Packaging Design From The Perspective Of Consumption Alienation, Guo Jingzhi, Xu Ming

Food and Machinery

In the context of contemporary food consumption, food packaging has gradually shifted from a tool for product protection and information transmission to an important cognitive interface that influences consumer perception, judgment, and choice. Existing studies in this field mainly focus on functional optimization, behavioral guidance, and cultural expression, while insufficient attention has been paid to how packaging design affects consumer cognitive processes. This paper introduces the theoretical perspective of consumption alienation and employs literature analysis and comparative case studies to construct a three-layer analytical framework of “judgment–choice–meaning.” Furthermore, it proposes a regression-based analytical pathway centered on comprehensibility, choice support, and …

Staff Education On Improving Abnormal Involuntary Movement Scale (Aims) Documentation And Monitoring For Adult Psychiatric Patients Prescribed Antipsychotic Medications In An Outpatient Clinic, Simisola M. Asekun

Walden Dissertations and Doctoral Studies

In outpatient psychiatric settings, inconsistent recordkeeping and a lack of systematic monitoring continue despite the availability of established tools like Abnormal Involuntary Movement Scale (AIMS). The goal of this Doctor of Nursing Practice project was to enhance the documentation and quality improvement through staff education and monitoring of AIMS in adult mental patients receiving antipsychotic medications. Tardive dyskinesia (TD) is still a serious, frequently misdiagnosed side effect of long-term antipsychotic therapy that significantly affects functional outcomes and patient quality of life. This project was guided by the following practice-focused question: How does implementing standardized AIMS documentation and electronic health record …

Assessing Computer Vision Based Conflict Detection In Uas Traffic Monitoring Under Secure Communication Constraints, Fadjimata Issoufou Anaroua

Doctoral Dissertations and Master's Theses

The rapid growth of Unmanned Aircraft Systems (UAS) and Advanced Air Mobility (AAM) is creating a new low-altitude airspace ecosystem where drones, air taxis, service suppliers, communication networks, sensors, and ground-based monitoring systems must work together safely. Within this ecosystem, UAS Traffic Management (UTM) is expected to provide a digital framework for coordinating operations beyond traditional air traffic control. However, reliable integration also requires resilient monitoring methods that can detect non-cooperative aircraft, protect communication links, and maintain timely situational awareness under real-world constraints.

This dissertation examines how computer vision can support cooperative monitoring systems such as Remote ID and ADS-B …

Trustworthy Artificial Intelligence For Real-Time Quality Assurance In Additive Manufacturing, Md Shafikul Islam

LSU Master's Theses

Additive manufacturing requires quality assurance methods capable of detecting process anomalies before defects propagate across subsequent layers. This thesis develops a trustworthy artificial intelligence framework for real-time surface anomaly detection in Fused Deposition Modeling (FDM) using laser-derived depth maps and Vision Transformers (ViTs). Conventional convolutional models aggregate global context gradually through stacked local kernels, which can limit their sensitivity to spatially distributed surface deviations. The proposed approach instead tokenizes depth-map patches and applies global self-attention to classify four process conditions: normal printing, under-extrusion, over-extrusion, and empty or void regions. The framework combines token-level attention visualization, vanilla saliency, Integrated Gradients, and …

Comments Re: Regulation For Federal Financial Assistance, Fred D. Ledley, Edward Zhou, Brian C. Fox

CISI Publication

This comment focuses on the proposed modifications to §200.205 “Federal Agency Merit Review of Proposals” and §200.340 “Termination and suspension” of Title 2 of the Code of Federal Regulations. We argue that the pre-issuance review, discretionary termination provisions, and other constraints of federal research support that would be established under this proposal create impediments to the scientifically-driven process of discovery and innovation that has long provided the foundation for advances in American prosperity, influence, health, and wellbeing. Our comments focus specifically on federal support for biomedical research by the National Institutes of Health (NIH) for the purpose of advancing healthcare …

Facilitating Conditions And Gender Gaps: Predicting Intention To Adopt Digital Education Resources Among Teachers, Bijaya Shrestha, Virginia Clinton-Lisell

Education, Health & Behavior Studies Student Publications

This study examined factors shaping school teachers’ intention to adopt Digital Educational Resources (DER) in Kathmandu Valley, Nepal, based on the Unified Theory of Acceptance and Use of Technology (UTAUT). Factors included were performance expectancy, effort expectancy, social influence, facilitating conditions, and behavioural intention. Fifty-six (56) teachers completed an online survey measuring those factors. Among all the factors, facilitating conditions were the marginally significant positive predictor of behavioural intention to adopt DER. Male teachers reported marginally higher behavioural intention (p =.05) to adopt DER compared to female teachers. However, gender was not a significant moderator in relationship between behavioural intention …
