Published: January 2024

The ubiquity of IT (Information technology) for teaching at large is a reality that can be observed, including STEM education, which is the field of study of this research. In view of this situation, this work is intended to determine the role of IT in STEM (Science, Technology, Engineering, Mathematics) education. It was decided to conduct a systematic review based on PRISMA model and adding information obtained from the analysis of fugitive literature. The literature review was carried out on a total of 16 articles. The main inclusion criteria were a temporal selection from 2015 to March 2023, the inclusion of the terms IT and STEM in the title, abstract or keywords of the articles. The main results show an increasing tendency of this topic, especially in English research. Most relevant conclusions of the systematic review evidence a positive relationship between IT and STEM education, although some negative aspects are also highlighted as there is still a lack of resources and teacher training, leading to ineffective application of IT in STEM classes. The research results have important practical implications, it motivates teachers to research, propose and implement measures to enhance the role of IT in STEM education, while minimizing the limitations that have been identified.

Published: January 2024

In the 1980s of the twentieth century, universities in developed countries began to realize the growing gap between the capabilities of new graduate engineers and the actual requirements of engineering branches. The strong progress of technology requires engineers to have the intellectual abilities and necessary job-specific skills to master that progress. This paper focuses on Conceive, Design, Implement and Operate (CDIO) approach-based teaching for students majoring in electrical and electronic engineering technology at engineering universities in Vietnam to demonstrate the feasibility of the teaching model. The experimental method of synthesizing qualitative and quantitative results for 90 students in control and experimental classes was used. The experimental and control classes both had 45 students. SPSS software version 22 was used to gather data and evaluate the learning results of the two experimental and control groups. According to the findings of the T-test analysis of the independent variables for the two groups, the experimental class performed better in academics and had students in the experimental group who were more satisfied with their post-test scores. This result contributes to confirm that the use of the CDIO-based teaching model in Vietnam is effective for students majoring in electrical and electronic engineering technology.

Resultado: Com base nas evidências levantadas, foi elaborado um fluxograma contemplando recomendações para diagnóstico e tratamento de TDAH em adultos. Conclusão: O protocolo proposto pode auxiliar a equipe assistencial no diagnóstico e tratamento de TDAH em pacientes atendidos no HUWC, evitando-se assim o desenvolvimento de quadros psiquiátricos secundários, tais como ansiedade, depressão e transtorno por uso de substâncias.
The mangled upper extremity: a principled approach to management
Authors: Song Ethan Y. , Meaike Jesse D. , Langdell Hannah C. , Mithani Suhail K.
Published: January 2024

A mangled upper extremity often involves injury to soft tissue, bone, nerves, and vessels and presents a unique challenge to hand surgeons. The complexity of such injuries requires a multidisciplinary approach to achieve an optimal functional outcome. After obtaining a thorough history and performing a secondary survey, initial management is built upon a strong understanding of the likelihood of limb salvage. Initiation of antibiotics upon presentation, timely and thorough surgical debridement, and early revascularization efforts should be pursued. The surgical team should create a long-term plan involving skeletal stabilization and soft tissue reconstruction along with postoperative rehabilitation and social support. This article reviews current concepts of upper extremity limb salvage and recommendations for surgical management of the mangled extremity.
Potential roles of telomeres and telomerase in neurodegenerative diseases
Authors: Shao Jun , Wang Jing , Li Bo , Liu Chuanbin
Published: January 2024

Telomeres, essential DNA-protein complexes located at chromosome ends, play a critical role in preventing chromosome fusion, recombination, and degradation, thus ensuring genomic stability. When telomeres reach a limiting shortened length, they will activate DNA damage checkpoints, stop cell division and trigger replicative senescence. Telomerase is composed of RNA and protein, which can synthesize telomeres repeat sequences, and elongate telomeres. Studies have shown that telomere length (TL) and telomerase activity are closely involved in aging, aging-related degenerative diseases, and tumors. Neurodegenerative diseases (NDDs) are one of the major aging-related diseases caused by both genetic and environmental factors, characterized by insidious onset, difficult diagnosis, irreversible disease progression, and lack of effective treatments, which brings a heavy burden to society and families. Currently, many studies have noted variations in leukocyte telomere length (LTL) and telomerase activity in NDDs, suggesting a vital role for telomeres and telomerase in NDD pathogenesis. This review explores the relationship between TL and NDDs, examines telomerase as a potential therapeutic target, and discusses emerging biomarkers and intervention strategies for NDD diagnosis and treatment.

Authors: Bruton Ronald , Gilliland Tracie , Shou John , Lambert Naomi , Woods Crislyn , Barrett Tyler
Published: January 2024

Caused by age or trauma, collapsed connective tissue can cause nerve entrapment and damage within the tarsal tunnel. Tarsal tunnel syndrome is relatively underdiagnosed. This study presents an intervention targeting damaged tissues surrounding the nerves and replacing the structural cushioning with a Wharton’s jelly tissue allograft. The eight selected patients from four clinical sites had tarsal tunnel-related defects. Patient outcomes were tracked on a 90-day calendar utilizing the Numeric Pain Rating Scale (NPRS) and the Western Ontario and McMaster University Arthritis Index (WOMAC). All patients had failed standard care practices for at least six weeks. Each patient received a Wharton’s jelly tissue allograft to sites around the affected tarsal tunnel. No patients experienced adverse reactions. Percent change calculated from the initial application to the 90-day follow-up showed an improvement of 59.43% in NPRS and a 37.58% improvement in WOMAC. This study provides evidence that WJ allograft applications are safe, minimally invasive, and efficacious for patients who have failed standard care treatments for tissue defects associated with Tarsal Tunnel syndrome. Limitations include the small cohort size and nonblinded nature. The results of this study warrant further research to confirm the efficacy, optimal dose, protocol, and durability of Wharton's jelly.
‘Belief-Consistent Information Processing’ vs. ‘Coherence-Based Reasoning’: Pragmatic Frameworks for Exposing Common Cognitive Biases in Intelligence Analysis
Authors: Barrows Matthew , Ellison George
Published: January 2024

Aileen Oeberst and Roland Imhoff’s remarkable paper (Perspectives on Psychological Science 2023; 18: 1464-87). should be compulsory reading for all intelligence analysts. It offers a tantalisingly parsimonious explanation comprising the combination of strongly held prior 'beliefs' coupled with subsequent 'belief-consistent information processing' (akin to confirmation bias) - an explanation that simplifies understanding of a vast array of cognitive biases, and thereby suggests that all of these might be attenuated through the application of accessible analytical and assessment practices. What this means for intelligence analysis will be determined by the explicit and implicit 'beliefs' (or, more generally, ‘value[s]’) attributed to any evidence available, and any insight generated, to reduce decision-makers’ uncertainty and unsubstantiated certainty, and thereby offer them future advantage. Analysts are well aware that different sources of evidence (whether empirical, theoretical or entirely speculative) can assign different types and amounts of ‘prior value’ to the information available for intelligence analysis and assessment. Acknowledging such value as a potential driver of subsequent confirmation bias should help analysts guard against any inherent tendency to preference evidence solely on the basis that this was initially considered most ‘valuable’. Instead they should subject all evidence and all insight – regardless of perceived ‘value’ – to a consistent battery of systematic, rigorous and robust evaluation.
A Research on the Electrical Conductivity of Hypereutectic Al-Si Compacts and B4C added Composites Produced by Conventional, Microwave and Spark Plasma Sintering Techniques
Authors: OZER Melika
Published: January 2024

In the present study, hypereutectic Al-Si alloy compacts and Al-Si/B4C composites were produced by conventional, microwave and spark plasma sintering techniques. The effects of sintering techniques and B4C particle addition on microstructural properties, density, hardness and electrical conductivity were investigated. The microstructures were examined with an optical microscope. Densities were measured using the Archimedes technique. Electrical resistance measurements were made with the four-point probe measurement technique. Elemental Al grains, master alloy grains and primary Si particles were determined in the microstructures of all samples. The addition of 15 wt% B4C caused the porosity rate to increase in the samples. Samples produced with SPS technique gave ≈80% higher hardness values than samples produced with CS and MWS. Compared to the samples produced with CS and MWS, the samples produced with SPS gave higher electrical conductivity values. Electrical conductivities were decreased as the weight percentage of B4C increased in all samples.

Soil microbiome plays key role in plant health. Native soil microbiome inoculation, metagenomic profiling and high-throughput cultivation require efficient microbe extraction. The sonication and oscillation are most common methods to extract soil microbiome. However, the extraction efficiency of those methods has barely been investigated. Here, we compared the culturable microbe numbers, community structures and alpha diversities among the methods including sonication, oscillation, centrifugation and their processing time. The results showed that, sonication significantly increases culturable colony number compare with oscillation and centrifugation factors. Furthermore, sonication strategy shows a main factor influence extraction efficiency, but increased sonication time can recovery this impact. Finally, processing times of extraction show a significant negative relationship with α diversity among extracted microbiota. In conclusion, sonication is a main factor for enrich in-suit microbiota, and increased extraction time significantly decrease α diversity of extracted microbiota. These results can provide insights into the isolation and utilization of microorganism source.

Investigating Emotional Impressions in Robots Using Clothing Colors
Authors: Sugiyama Takashi , Kanoh Masayoshi
Published: January 2024

Expressing emotions is essential for ensuring smooth communication between people. In the context of human-robot symbiosis, robots are also required to express emotions. Although one method of robot emotion expression involves using LEDs or other forms of light to display colors, considering the possibility of expressing emotions through clothing colors is also necessary. In this study, we developed a simple robot called the “Tilting Robot,” which only performs simple tilting motions to investigate whether changes in the robot’s clothing color would affect the expressed emotions. In the experiment, participants were divided into two groups: motion and posture groups. The motion group was shown videos of the robot’s motion whereas the posture group was shown still images of the robot’s posture. The results showed that the red clothing in the posture group significantly expressed anger, whereas the blue clothing in the motion group significantly expressed sadness. The rating for blue clothing was 4.04 ± 1.30, which was near “undecided.” This suggests that blue clothing does not necessarily intensify the emotion of sadness, but other clothing colors may weaken its expression. The rating for red clothing was 2.86 ± 1.06, which was lower than “undecided.” This suggests that red clothing may not express anger, but could give an impression of vitality.
Dynamic Generation of Subordinate Clusters Based on Bayesian Information Criterion for Must-Link Constrained K-Means
Authors: Shimizu Shota , Sakayauchi Shun , Shibata Hiroki , Takama Yasufumi
Published: January 2024

This paper proposes a constrained K-means clustering method that dynamically generates subordinate clusters based on Bayesian information criterion (BIC). COP K-means, which considers a pairwise constraints in partition-based clustering, have difficulty in handling the case that a must-link is given to instances located far away from each other. To address this problem, the proposed method generates subordinate clusters that have a must-link to a master cluster during a clustering process. The final clustering result is obtained by merging the subordinate clusters. The proposed method determines whether to generate subordinate clusters or not based on the BIC. This paper also introduces an idea of mitigating the sensitivity to initial position of subordinate clusters. The effectiveness of the proposed methods is shown through the experiment with two synthetic datasets.

Authors: Osagie Efosa , Ji Wei , Helian Na
Published: January 2024

In recent times, medical imaging has become a significant component of clinical diagnosis and examinations to detect and evaluate various medical conditions. The interpretation of these medical examinations and the patient’s demographics are usually textual data, which is burned in on the pixel content of medical imaging modalities (MIM). Example of these MIM includes ultrasound and X-ray imaging. As artificial intelligence advances for medical applications, there is a high demand for the accessibility of these burned-in textual data for various needs. This article aims to review the significance of burned-in textual data recognition in MIM and recent research regarding the machine learning approach, challenges, and open issues for further investigation on this application. The review describes the significant problems in this study area as low resolution and background interference of textual data. Finally, the review suggests applying more advanced deep learning ensemble algorithms as possible solutions.
Dynamic Real-Time Analysis of Network Attacks Based on Dynamic Risk Probability Algorithm
Authors: Wang Chao , Dong Jiahan , Guo Guangxin , Li Bowen , Ren Tianyu
Published: January 2024

With the rapid development of Internet technology and its application, the existence of network vulnerabilities is very common. Attackers may use the defects of software, hardware, or system security policy in the network system to access or destroy the system without authorization. How to nip in the bud and carry out a safety risk assessment and early warning is an urgent problem to be solved. Based on the overall assessment of the risk factors in the whole network, the more dangerous nodes are found and priority measures are taken. The method proposed in this paper can reflect and predict the actions of attackers, repair, and adjust the previously predicted probability. It is compared with the method that evaluates the uncertainty in the network solely by calculating the static probability. The proposed new ideas and methods better reflect the real-time changes in the actual environment of the Internet, thereby better responding to the actual situation. This method can be well applied to threat detection, threat analysis, and risk assessment of monitoring system networks, enabling monitoring network managers to evaluate and protect the security of real-time power grids. It is of great significance to effectively defend against network attacks, ensure system security, and study the resistance of control systems under network attacks.
An Improved Multi Target Ship Recognition Model Based on Deep Convolutional Neural Network
Authors: Li Shu-Hua , Yan Feng-Long , Li Ying-Qiu
Published: January 2024

Deep learning is the major technique used to identify objects in images captured by the synthetic aperture radar (SAR). While SAR images can be used to identify ships in general, detecting multiple ships or small vessels in these images in complex contexts remains an outstanding challenge. This study proposes a model of detection based on the improved PP-YOLO deep convolutional neural network that can identify multiple ships as well as small vessels in complex scenarios from SAR images. The histogram equalization algorithm is first used to preprocess the SAR images, and then the initial anchor box is optimized by using the shape similarity distance-based K-means clustering algorithm. Following this, the accuracy of the training network is improved based on the feature pyramid network and an attention mechanism. The experimental results show that the average accuracy (average precision) of the model was 94.25% at 41.63 frames per second on the GF-3 and the Sentinel-1 SAR datasets, superior to those of YOLOv3 (Darknet), YOLOv7, FPN (VGG), SSD, Faster R-CNN, and PP-YOLO (RestNet50-vd). The model also satisfies the demands of real-time detection.

Masker adalah perlindungan pernafasan yang digunakan sebagai metode untuk melindungi individu dari menghirup zat-zat bahaya atau kontaminan yang berada di udara. Meskipun masker sangat diperlukan untuk menghindari penyebaran virus Corona, namun pembuangan masker mengancam lingkungan. Masker medis terdiri  dari  tiga  lapisan,  lapisan luar  dan  lapisan  dalam  adalah  kain  non-woven yang tahan  air dan lapisan tengah adalah bahan  yang  meleleh. Sebagian besar, komposisi kimia dari masker medis adalah polipropilena. Pada review ini akan dibahas penggunaan limbah masker yang mengandung polipropilena sebagai bahan aditif dalam pembuatan campuran aspal. Metode yang digunakan adalah studi literatur dari peneliti terdahulu dan analisis penambahan limbah masker yang mengandung polipripilena yang berpengaruh terhadap campuran aspal. Sumber utama refrensi artikel ini berasal dari Research Gate, Science Direct, dan Google Scholar. Ditemukan bahwa unsur senyawa yang paling dominan pada masker medis adalah Si (Silika) sebesar 59,11%. Penambahan silika pada campuran aspal dapat meningkatkan ketahanan terhadap kerusakan alur, peningkatan nilai modulus, dan umur fatigue.

تعد بكتيريا Helicobacter pylori (H. pylori) المسبب الرئيسي في التهاب المعدة والقرحة الهضمية وأمراض سرطان المعدة. تساهم مستقبلات Toll-like receptors (TLRs) في الاستجابة المناعية الذاتية من خلال المسبب المرضي المرتبط بالأشكال الجزيئية Pathogen-associated molecular patterns (PAMPs) المشتقة من H. pylori والكائنات الدقيقة الأخرى بالإضافة إلى التلف المرتبط بالأشكال الجزيئية damage-associated molecular patterns (DAMPs) المشتقة من الخلايا المضيفة، مثل الخلايا السرطانية أو الخلايا الميتة أو المحتضرة أو المنتجات المنبعثة من الخلايا استجابة لبعض الإشارات منها نقص الأوكسجين. اشتملت الدراسة الحالية على خزعات معوية مأخوذة من 88 مريضًا مصابون باضطراب المعدة والأمعاء اضافة الى 21 مجموعة لا تعاني من تلك الاعراض. وشملت التشخيصات السريرية لهذه المجموعات بعد الفحص بالمنظار التهاب المعدة والقرحة الهضمية وسرطان المعدة. تم إجراء الكشف عن بكتريا H. pylori باستخدام PCR لتضخيم جينات ureC وureA بمساعدة بادئات محددة. صورت الحزم بعد الترحيل الكهربائي للهلام وتم تقدير التعبير عن جينات TLR2 وTLR10 في عينات خزعات المعدة بالطريقة النسبية. تشير النتائج الحالية إلى أن القابلية للإصابة باضطراب المعدة والأمعاء تزداد مع تقدم العمر، اذ كان عمر معظم المرضى أكثر من 30 عامًا (68 من أصل 88 مريضًا) ويمثلون 77.2٪ من المرضى. تحفز البكتيريا التعبير للجينيTLR2 و0TLR1 وسجل الجين TLR2 11.11-fold في مرضى التهاب المعدة، و7.65-fold في مرضى القرحة الهضمية، بينما انخفض الى6.25-fold في المرضى الذين يعانون من سرطان المعدة، وانخفض folding مع تقدم المرض. من ناحية أخرى، سجل جين TLR10 أعلى 5.01-fold في مرضى القرحة الهضمية، تلتها 4.78-fold في مرضى التهاب المعدة، و3.10-fold في سرطان المعدة. سجل التعبير عن جيني TLR2 وTLR10 قيمة معنوية اعلى (p ≤ 0.01) في مجموعة المرضى مقارنة بمجموعة السيطرة. في مرضى التهاب المعدة والقرحة الهضمية وسرطان المعدة، كان التعبير الجيني TLR2 وTLR10 أعلى من المجموعة السليمة، في الوقت الذي سجل جين TLR2 أعلى من جين TLR10.
Uma imagem e vários significados: o sentido de trabalhar com a produção cinematográfica em sala de aula
Authors: Santos Douglas Manoel Antonio de Abreu Pestana
Published: January 2024

Este estudo investiga a incidência e o impacto de relações intertextuais em cenas cinematográficas, destacando como essas interações transcendem o enredo principal e enriquecem a narrativa visual. Através de uma análise meticulosa conduzida por cinéfilos, o texto revela como detalhes aparentemente menores nas cenas podem desvendar curiosidades, erros e estabelecer conexões inovadoras entre a cinematografia e outras expressões artísticas. Além disso, o artigo argumenta que uma observação detalhada e crítica de obras de arte ou filmes é fundamental para identificar elementos sutis, tais como mensagens subliminares ou "easter eggs". Esses elementos não só intensificam a experiência interpretativa, mas também contribuem significativamente para a apreciação e entendimento mais profundo do tema abordado. A pesquisa conclui enfatizando a importância de não se limitar à apreciação superficial das obras, incentivando uma exploração mais aprofundada das diversas camadas de significado que elas possuem.

A pandemia do covid-19 afetou diretamente o método de aprendizagem e ensino. Nesta pesquisa interessou-se investigar como os professores de Matemática conseguiram superar os desafios encontrados nesse período. Para que se pudesse compreender as dificuldades e entender as estratégias usadas pelos professores, foi necessário submeter os sujeitos a um questionário online, distribuído através do Whatsapp e formulado na plataforma Google Forms. A abordagem utilizada para se desenvolver esta pesquisa foi um estudo de caso, pois o fenômeno estudado influenciou diretamente os métodos de ensino dos professores entrevistados. O estudo de caso permitiu que nós analisássemos as respostas a partir de 7 (sete) perspectivas diferentes, cada professor utilizou do seu contexto histórico e experiência para expressar as suas dificuldades enfrentadas e estratégias utilizadas durante o ensino remoto. Notou-se que a falta de conhecimento em ferramentas tecnológicas prejudicou o ensino, uma vez que os professores precisaram se adaptar rapidamente ao ambiente online. Muitos professores demoraram para conseguir produzir aulas interativas que engajassem os alunos e “prendesse” a atenção dos mesmos, causando assim um déficit no ensino da Matemática.
