Authors: Sharma Kapil , Kalaiselvan Vivekanandan , Chaudhary Priyanka , Kalaivani Muthusamy
Published: February 2025

Dry eye disease is defined as a multifactorial disease of the tears and ocular surface that results from tear film instability that leads to visual disturbance and ocular discomfort. A better understanding of the pathophysiology and etiology of dry eye disease is necessary for efficient management and treatment of the disease process. Eye on chip (type of organ chip) acts as an alternative model for disease modeling. These chips help in exploration of facets of human disease and development which is not accurately recapitulated by animal models. This technology will increase our understanding of the basic physiology of different eye structures and enable us to interrogate unknown aspects of ophthalmic disease pathogenesis and serve as clinically-relevant surrogates for the evaluation of ocular therapeutics. These chips play important role in drug development process and can be used in clinical trials for drug testing in place of animals. Overall, these chips reduce the cost of drug development process by increasing the success rate of clinical trials they also help in avoiding ethical issues related to animal testing.

Authors: Pham Dinh Du
Published: February 2025

In this paper, nanostructured copper oxide materials were prepared in N’N-dimethylformamide solvent from Cu(NO3)2×3H2O and benzene-1,4-dicarboxylic acid precursors. The obtained copper oxide nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TG/dTG), nitrogen adsorption-desorption isotherms, scanning and transmission electron microscopy (SEM and TEM). At 120°C synthesis, the CuO crystalline phase was mainly formed, while at 180-220°C, the Cu2O and Cu crystalline phases were also formed in addition to the CuO crystalline phase. The adsorption or degradation ability based on H2O2/catalyst system of copper oxide nanoparticles for rhodamine B removal was also evaluated. The results showed that copper oxide nanoparticles had low adsorption capacity for rhodamine B, but high catalytic activity to decompose rhodamine B in aqueous solution with hydrogen peroxide as the oxidizing agent.

More Than Just a Laugh: The Multilevel Viewpoint Structures of Reaction Memes
Authors: Nishizaki Mona
Published: February 2025

In an era where memes dominate digital communication, their significance extends far beyond humor—they serve as complex, multimodal expressions of culture, discourse, and collective identity. Yet, despite their ubiquity, the ways in which they communicate meaning are not well understood. One of the reasons is that memes require interpretation and can be understood differently by different viewers, making their meaning inherently fluid and participatory. Departing from traditional semiotic perspectives, this paper applies a construction grammar approach to in which memes are understood as emerging multimodal constructions and meaning is structured within a multi – level discourse viewpoint space. This study explores the multimodality of memes through an analysis of the multilevel viewpoint structure of reaction memes, with a specific focus on the integration of frame metonymy, meme characters, and intersubjectivity. This study confirms that memes function as multimodal constructions in which meaning is created through the interaction of text, images, and shared cultural knowledge within a discourse point of view space (Dancygier & Vandelanotte, 2017). Analyzing reaction memes like 'This Is Fine' and 'Press X to Doubt' reveals varying degrees of intersubjectivity, with some memes relying on universally understood concepts (e.g., fire as danger) and others requiring niche framing knowledge (e.g., video game mechanics) to be fully interpreted.

Authors: Manurung Cristo Mori Romario , Delvian D. , Indirawati Sri Malem
Published: February 2025

This research collects and analyzes quantitative data on two research variables: the management of solid medical waste and the behavior (knowledge, attitudes, and actions) of human resources (HR), specifically nurses, environmental health officers, and cleaning service officers. The research population comprised 274 individuals, including nurses, environmental health officers, and cleaning service officers. The sampling technique was purposive, with the inclusion criteria being a work period of more than 2 years. Data was collected through interviews, observations, and document reviews at Drs. H. Amri Tambunan Hospital, Deli Serdang Regency. The data collected was analyzed using frequency distribution with the SPSS 20 application. The results showed that the knowledge of nurses, environmental health officers, and cleaning service officers regarding solid medical waste management was categorized as good (61.1%). The attitudes of these personnel were all in the good category (100%). In comparison, their actions in managing solid medical waste were categorized as good (85%)—the management of solid medical waste at Drs. H. Amri Tambunan Regional General Hospital, Deli Serdang, involves several stages. The reduction and sorting processes still rely on chemical products for cleaning, and the storage at the Temporary Storage Facility (TPS LB3) does not include refrigeration facilities for cases where solid medical waste is stored for more than 2 days after production. Additionally, during transportation, officers are sometimes observed not wearing complete personal protective equipment (PPE) such as helmets, face masks, eye protection, aprons, foot protectors, and gloves. Furthermore, the use of chemical disinfection for waste processing has not received approval from the Environmental Service.

Authors: Güvenç Alparslan , Atay Lütfi
Published: February 2025

This study examines the Bicycle-Friendly Accommodation Facility Certificate implemented by Ministry of Culture and Tourism of Turkiye within the framework of sustainable tourism. By comparing this certification system with international examples, the research identifies similarities and differences in governance, criteria, and inspection processes. The findings reveal notable commonalities and distinctions among the certification systems. While all systems feature mandatory components such as secure parking, repair tools, and tailored nutritional services, the Turkish model stands out with its state-led, legally grounded framework and its points-based evaluation system, which is designed to encourage service enhancements. However, the study also identifies challenges in post-certification inspections and international visibility, which may limit the model's impact. The findings suggest that aligning Turkiye's certification system with best practices from international models could enhance its effectiveness and foster the growth of bicycle tourism. The insights derived from this research offer actionable guidance for policymakers and stakeholders seeking to promote sustainable tourism practices on a global scale. These insights include the identification of gaps in inspection processes, the enhancement of international cooperation, and the adoption of innovative solutions.

Abstract: Liquid photonic crystal (LPC) is a promising new material in the field of sensing, display, printing, and coating due to its unique fluidity, metastability, and reversibility in colloidal assembly. However, it is a big challenge to prepare LPC materials in an efficient, controllable, and eco-friendly way. In this work, an electrically-driven colloid concentration process was developed for the efficient synthesis of LPC. The key for the synthesis was that the electrophoretic process produced a locally concentrated but “agglomeration-free” colloidal solution, which spontaneously turned to LPC after being kept standing for a few minutes. The synthesis possessed good universality and reproducibility for LPCs composed of different particles and solvents. Its efficiency could be improved by tuning the particles’ surface charge, the dielectric constant and viscosity of the solvent, as well as the external field conditions. More importantly, it could be developed into a large-scale and green process without chemical wastes compared to the previous synthetic methods.

The Application of AIGC in 3D Graphic Design Courses
Authors: Wang Jiuchong
Published: February 2025

AIGC, which stands for Artificial Intelligence Generated Content, is a new form of content creation following PGC and UGC. Its rise is due to breakthroughs in deep learning technology and the increasing demand for digital content. AIGC can create new forms of digital content generation in multiple fields such as dialogue, images, and videos based on models trained with large amounts of data. In art design courses, AIGC can expand creativity, improve efficiency, and achieve personalized design. Taking the Cinema4D teaching course as an example, AIGC can quickly generate renderings based on sketches during the modeling process, reducing the debugging phase; it can output initial drafts that match the design style in a short time during the rendering stage; and it can also rapidly generate multiple posters and character portrait materials that fit the brand's tone for advertising design. Integrating AIGC into Cinema4D teaching helps students enhance their design capabilities and adapt to the new trends in industry development.

Mario Pannunzio alias Diogene? Ipotesi sull’attribuzione degli articoli da Cinecittà per «L’Ambrosiano»
Authors: Vignati Rinaldo
Published: February 2025

Mario Pannunzio è oggi ricordato soprattutto come direttore del settimanale «Il Mondo». Prima di fondare e dirigere questa rivista, e dedicarsi soprattutto alla politica, Pannunzio aveva coltivato interessi di varia natura, dedicandosi a esperienze pittoriche, dirigendo riviste letterarie e occupandosi di cinema. In ambito cinematografico svolse attività di critico (in particolare per «Omnibus») e di sceneggiatore (per alcuni film di Mario Camerini e di Duilio Coletti). Questo articolo, partendo da alcuni documenti ritrovati nel Fondo Mario Pannunzio conservato presso l’Archivio Storico della Camera, avanza l’ipotesi che siano attribuibili a Pannunzio anche alcuni articoli sulla lavorazione dei film negli studi di Cinecittà apparsi sul quotidiano milanese «L’Ambrosiano» nel corso del 1938 e firmati con lo pseudonimo Diogene. Per quanto non vi sia una prova definitiva che la attesti con certezza, l’esame dei documenti dell’Archivio e le assonanze che emergono dal confronto tra gli articoli di Diogene e le recensioni che Pannunzio pubblicava nello stesso periodo su «Omnibus» rendono altamente probabile l’attribuzione.

Published: February 2025

This paper proposes an intelligent plastic waste classification system based on the Deep Learning model and Delta robot. This system includes a Delta robot, a camera, a conveyor, a control cabinet, and a personal computer. The system applies Transfer Learning with the pre-train YOLOv5 model to detect plastic waste in real-time. The best model is selected with the best weight by evaluating the results of the pre-train model to classify different types of plastic waste and determine the positions of the waste by Bounding box. Then, these positions are converted into the Delta robot’s coordinate system by the formula obtained from the transformation matrix and the position of the camera. Finally, the computer processes and transports data to control the Delta robot to classify plastic waste in the conveyor. Afterward, a variety of classification experiments with more than 1000 samples in two different lighting conditions were conducted. The results illustrate that the computer vision and deep learning model achieve excellent efficiency with the best-performing case having a Precision of 96% and a Recall of 97%. In conclusion, the experimental results in this paper demonstrate that the proposed intelligent plastic waste classification system delivers high performance both in terms of accuracy and efficiency and has much more potential for further development.

Published: February 2025

Trong kỷ nguyên giáo dục 5.0, trí tuệ nhân tạo (AI) trở nên phổ biến và việc vận dụng chúng vào giáo dục đã đạt được những hiệu quả nhất định. Ngoài ra, chúng cũng mang lại nhiều lợi ích như việc cá nhân hóa học tập hay thúc đẩy sự tham gia học tập người học. Bên cạnh đó, nhiều thách thức được đặt ra về mặt đạo đức trong việc sử dụng trí tuệ nhân tạo. Người dùng AI trong giáo dục cần phải tuân thủ những nguyên tắc đạo đức nhằm đảm bảo tính minh bạch, sự công bằng và bảo vệ quyền riêng tư của người học. Khác với nền giáo dục 4.0, khi chỉ chú trọng về công nghệ, giáo dục 5.0 đã có bước chuyển mình, chú trọng hơn vào yếu tố con người, tính nhân văn trong giáo dục, đạo đức trở thành yếu tố thiết yếu hơn bao giờ hết khi lấy con người làm trung tâm. Do đó, việc đảm bảo AI được sử dụng một cách có tinh thần trách nhiệm và không gây hại cho người sử dụng và người chịu ảnh hưởng là điều cần thiết. Ngoài ra, bài nghiên cứu còn đề cập những thứ mà một người công dân số cần có để có thể thích ứng với nền giáo dục 5.0. Đây cũng là phần quan trọng trong việc xây dựng một môi trường học tập, phát triển an toàn và hiệu quả.

VMD-SVM-based Retail Product Demand Forecasting Model
Authors: Zhu Aiyuan
Published: February 2025

This study addresses the issues of noise and volatility in retail inventory forecasting by proposing a hybrid model based on Variational Mode Decomposition (VMD) and Support Vector Machine (SVM). Existing methods often struggle to handle noise in time-series data, which affects prediction accuracy. To overcome this, we decompose the raw time-series data into multiple modes using VMD, effectively removing noise and capturing the primary trends. The processed data is then modeled and predicted using SVM. The experiments first compare various machine learning models on the raw data, followed by VMD preprocessing to assess its impact on model performance. The results show that VMD significantly improves prediction accuracy, with SVM's R² increasing from 0.4039 to 0.9214. This research provides an effective solution for retail inventory forecasting, demonstrating the advantages of VMD in handling complex time-series data.
Food detection and volume estimation for nutritional analysis
Authors:   Sinhgad College of Engineering, Vadgaon Bk, Pune, Nale Komal Dilip
Published: February 2025

A healthy lifestyle and the prevention of chronic illnesses like diabetes and obesity depend on the precise calculation of dietary nutrition values, including calories, proteins, and carbs. Automated food recognition and volume estimate from photos is a viable solution to the problems with traditional nutritional assessment approaches, which rely on self-reporting and are prone to mistakes. Real-time nutrition estimate smartphone apps have been made possible by recent developments in machine learning (ML) and deep learning (DL). Techniques for food categorization, segmentation, and volume estimation that are used in automated dietary assessment systems are examined in this paper. Traditional machine learning (ML) techniques like support vector machines and k-nearest neighbors were used in early research, but convolutional neural networks (CNNs) and optimization techniques like fuzzy clustering and evolutionary algorithms are used in more recent studies. Additionally, the research emphasizes the difficulties in food segmentation, the use of picture datasets like Food-101, and the incorporation of depth estimate methods for volume measurement. Automated nutritional assessment systems provide increased accuracy and user engagement with the growing usage of AI-driven models, opening the door to better public health nutrition programs. For thorough nutrition estimate, future studies should concentrate on enhancing segmentation methods, diversifying datasets, and combining multi-modal data sources.

Published: February 2025

Mental health awareness has become an important component of public health in Malaysia, particularly in terms of young children's mental well-being. This qualitative study explores mental health experts' perceptions of awareness regarding young children's mental health issues in Malaysia. Nine themes emerged from semi-structured interviews with professionals such as psychiatrists, clinical psychologists, and non-governmental organisation representatives. These include seeing mental health as a spectrum, the persistence of stigma and cultural barriers, the influence of early childhood experiences, and the significance of personalised treatment approaches like play therapy. The findings illustrate both progress and obstacles in Malaysia's mental health strategy, revealing generational shifts in views as well as the need of supporting family contexts. The study emphasises the importance of focused interventions and enhanced knowledge for reducing stigma and improving mental health outcomes in early children. Further research should look into the changing role of cultural dynamics and media in shaping mental health beliefs.
