Authors: Mamassi Maria Eleni , Ioannidou Dimitra , Deligiannis Stavros , Tsakiridis Petros
Published: May 2024

Steel hydrogen embrittlement (HE), a complex and multifaceted issue, can lead to sudden and catastrophic failure, without significant plastic deformation, making it a critical concern in the industrial sector. The present investigation focuses on the evaluation of HE effects regarding microstructure, mechanical properties degradation and type of fracture of AISI 1010 low-carbon steel, after accelerated hydrogen cathodic charging. Hydrogen was diffused electrolytically in 0.2 Μ H2SO4 solution, containing 3g/L of NH4SCN, using a cathodic current density of 10 and 20 mA/cm2, for 6 and 18 h. Mechanical properties were investigated through slow-rate tensile tests, as well as Charpy V-notch (CVN) impact tests, to determine the value of fracture toughness, both in uncharged and electrochemically pre-charged specimens. Vickers microhardness tests were conducted on the cross-sections of the hydrogen charged samples to evaluate embrittlement susceptibility, due to the presence of dissolved hydrogen. The microstructure modification was carried out through light optical (LOM) and scanning electron microscopy (SEM), in conjunction with an energy-dispersive X-ray detector (EDS). Slow scan X-ray diffraction (SSXRD) was also conducted for crystal structure analysis. The microstructure analysis showed the presence of large amounts of secondary cracks and cavities into the steel matrix, due to hydrogen diffusion and its accumulation at various sites. Hydrogen charging caused a significant gradual elongation decrease of the parent material, from 25% to 6.73%, in case of embrittlement at 20 mA/cm2 for 18h. Accordingly, after 18 h of exposure, the impact energy decrement was determined at 31.5%, at a current density of 10 mA/cm2, whereas the corresponding reduction at 20 mA/cm2 reached 68%.

Oncological patients may present with difficult-to-resolve oral lesions that impair their quality of life, and laser therapy can help these patients. This study sought to present a systematic review of the use of intravascular laser irradiation of blood (ILIB) and antimicrobial photodynamic therapy (aPDT) for oncological patients. Furthermore, it provides a brief report on a patient with laryngeal cancer who experienced cytotoxic symptoms such as oral mucositis and oral candidiasis while receiving aPDT and ILIB. A systematic search of PubMed, Scopus, Embase, Cochrane, Lilacs, Web of Science, Scielo, and Gray Literature was conducted, with no year or language restrictions, for primary clinical studies that used ILIB and aPDT to treat oral manifestations in oncological patients. In the brief report, aPDT was administered within the first five days, and ILIB was used for persistent lesions and pain. The review included five clinical studies. They included case reports, retrospective studies, randomized clinical trials, and non-randomized clinical trials. ILIB therapy combined with aPDT has been shown to reduce pain and promote faster healing when compared to not using ILIB. In our brief clinical case, healing was accelerated while pain and infectious inflammatory processes were reduced in the oral cavity. This neutralization of oral toxicity by combining aPDT and ILIB improved overall health, resulting in rapid healing of the oral lesions. The combination of aPDT and ILIB may be an effective therapy for the rapid recovery of oral lesions among cancer patients. More research is needed to better understand the effects of ILIB in oncology patients.
Has Coca-Cola treatment become the first-line therapy for gastric bezoars, both in general and specifically for western countries?
Authors: Delgado Galan Maria , Rabago Luis Ramon
Published: May 2024

Phytobezoars is a rare disease and less common in Western countries. The stomach is the primary site for these formations, and endoscopic treatment involving fragmentation and extraction has traditionally been the most effective approach. However, medical treatments using enzymatic and chemical agents, such as cellulase and Coca-Cola, aimed at dissolving the bezoars, have also been utilized, showing varying degrees of resolution success. Notably, the oral dissolution treatment with Coca-Cola has emerged as a promising, simpler, and more cost-effective method. The study by Liu et al represents an important step in clinical research on this topic, despite some limitations that need addressing for a more comprehensive understanding of its findings. Key considerations for future research include sample size calculation, endoscopic procedure details, outpatient vs. inpatient treatment, and detailed cost calculations. The study's exclusions, such as patients with upper gastric surgery, phytobezoars older than 14 d, and cases of gastroparesis, limit its applicability to broader populations, especially in Western countries. Given the promising outcomes of the Coca-Cola treatment, it's advocated as a first-line therapy for phytobezoars. Nonetheless, further research is essential to overcome these limitations. However special situations such as perforation or small bowel obstruction will require surgical treatment.
Recent Progress on Mechanism of Mechanical Abuse
Authors: Hao Wang Zhi , Tang Xuan , Zhou Youhang
Published: May 2024

With the rapid development of electric vehicles (EVs), lithium-ion batteries (LIBs) with high energy and power density have been widely applied as the power producer of EVs. However, the range of EVs has been criticized. To meet consumer demand for high power and long driving distances, the energy and power density of LIBs are getting higher and higher. However, LIBs with higher energy density are more prone to catastrophic thermal runaway (TR). In recent years, EV accidents due to TR of LIBs have been frequently reported, which makes consumers lose confidence in EVs. To solve the problem, we must understand the mechanism of LIBs TR, thereby reducing the likelihood of TR in EVs. However, the induction mechanism of LIB TR induced by mechanical abuse is sophisticated. This paper focuses on recent advances in the study of thermal TR characteristics of batteries caused by mechanical abuse, including bending, collisions, and penetration. The impact of various mechanical abuses on the TR characteristics of batteries has been summarized. From the onset of mechanical abuse conditions to the occurrences of TR, the interior evolution of the battery is discussed through experiment and theory, to reveal the processes of mechanical deformation and internal short-circuit (ISC) of LIBs. Additionally, an acceleration calorimeter and X-ray computed tomography (CT) are used to investigate the TR process and the evolution of temperature, voltage, and structure of battery components in the battery under mechanical abuse conditions. This paper aims to summarize the latest progress in the study of the mechanism of mechanical abuse-induced battery TR, to help engineers design safe batteries.

Published: May 2024

Churning loss is an important energy loss term for rolling bearings at high-speed condition. However, it is quite challenging to accurately calculate the churning loss. A CFD study based on unsteady Reynolds-Averaged-Navier-Stokes that resolves the gas-liquid interface was performed to examine the unsteady multiphase flow in a roller/ball bearing. In this study, the rotating motion of the cage, races, rollers/balls about the shaft as well as self-rotation of rollers/balls about their own axis were accounted to accurately predict the oil distribution in various parts of the bearings. A novel meshing strategy is presented to resolve thin gaps between the roller/balls and the races/cage while preserving the shape of balls/rollers, races and cage. Five rotational speeds of the shaft have been examined for roller bearing and ball bearing respectively. Additionally, effect of clearance between roller/balls and races is investigated. Of particular interest is to examine the mechanisms governing the process of oil feed and oil splash in the bearings and their effect on the churning power loss that the bearing incurs. The oil distributions near all components of interest have also been investigated to understand the overall oil churning process. Results show that the feeding of oil from the inlet section into the bearings is strongly dependent on the oil feed rate, rotational speed of the shaft, and the bearing design itself. Results are presented to show how the rotational speed of the shaft affects the nature of multiphase flow inside the bearings and its influence on the overall oil distribution in the bearings. The computational study was validated by comparing the computed churning power loss of the roller bearing at quasi steady operation with the experimental measurements and good agreements with experiments were found. Since the study is validated, the CFD strategy presented in this study to simulate the oil churning process in the bearings can be most useful in guiding the design and development of bearings and increase the efficiency of the electrification driving systems.
Comprehensive Assessment of Gasoline Spray Robustness for Different Plume Arrangements
Authors: Oh Heechang , Hwang Joonsik , Pickett Lyle
Published: May 2024

Ensuring spray robustness of gasoline direct injection (GDI) is essential to comply with stringent future emission regulations for hybrid and internal combustion engine vehicles. This study presents experimental and numerical assessments of spray for lateral-mounted GDI sprays with two different plume arrangements to analyze spray collapse characteristics, which can significantly deteriorate the atomization performance of fuel sprays. Novel spray characterization methods are applied to analyze complex spray collapse behaviors using diffusive back-illuminated extinction imaging (DBIEI) and 3D computed tomographic (CT) image reconstruction. A series of computational fluid dynamics (CFD) simulations are performed to analyze the detailed spray characteristics besides experimental characterization. Spatio-temporal plume dynamics of conventional triangle-pattern spray are evaluated and compared to a plume pattern with an inversed T pattern that has more open space between plumes. The results show that the triangular pattern, with plumes enclosed by other plumes, indicated significant spray collapse behavior under various conditions. The inversed-T pattern, the opened pattern where plumes are arranged not to have a closed volume, had better robustness against collapse due to an open layout, which prevents an imbalance of the local pressure field that may cause collapse. The approach applied in this study to mitigate spray collapse was verified to be effective and can be referenced in spray design to ensure the robustness of GDI sprays.
Early maladaptive schemas in sex offenders versus the characteristics of offences against sexual freedom
Authors: Oettingen Justyna , Gierowski Józef Krzysztof , Grabski Bartosz , Micek Agnieszka
Published: May 2024

This study examines the relationship between early maladaptive schemas (EMS) and the characteristics of offences committed by sex crime convicts.

The research uses data collected from 102 convicts. The Polish version of Young’s Schema Questionnaire (YSQ-S3-PL) was used to gauge the severity of EMS. The author’s self-made questionnaire used for making extracts from prison records, coupled with Beisert’s Violence Scale (2012), was employed to study the characteristics of the offences committed by the criminals under study.

A correlation was found between the characteristics of the committed criminal acts (choice of victim, the CSO’s modus operandi, sexual violence involved) and the type and severity of each EMS. Relevant for CSOs in the context of their criminal acts are 4 domains out of 5 and 11 EMSs out of 18.

The findings suggest that EMS contribute to criminal sexual behaviour. It may be important and useful to consider these structures when constructing models of preventive measures and planning therapeutic or proactive interventions. As a result, it would seem that convicted sexual offenders (CSO’s) require a customised approach including therapeutic models designed to address the specific maladaptive schema.
Implementing innovative strategy for visualising fingerprints on wet non-porous surfaces
Authors: Kollam Anjali , Jaitly Tamanna , Ganechary Pavan Kumar , Raghottam Prawahan , Aseri Vinay
Published: May 2024

Fingerprints are an important piece of evidence in crime investigation and play a key role in crime investigation due to their permanency, universality, uniqueness and of course availability. Utilization of water or any other liquids to destroy evidence by criminals is a very common practice. It becomes difficult to collect and analyse such evidence from underwater in terms of its forensic reproducibility, though not impossible. The methods employed are quite tedious, expensive and unreliable. There are many fingerprint powders accessible to the scientific examiners to recuperate and gather the unique fingerprint impressions submerged, the vast majority of them are for explicit materials like small particle reagent (SPR). The technique has been compromised by its downsides as it is highly toxic, very sensitive, low contrast and quite costly. An urgent and imperative need to foster an economical and effective, low cost fingerprint powder for underwater impressions by using the materials that are easily available. The present study was conducted to fulfil the same objective and proposes a modest unique fingerprint powder which provides great proficiency from a combination of surfactant sodium dodecyl sulphate (SDS) with chalk powder (yellow) and silver powder respectively.
The Naming of Railway Locomotives in Britain as a Cultural Indicator, 1846–1954
Authors: Coates Richard
Published: May 2024

From the birth of railways in Britain in the early nineteenth century, it rapidly became usual (but not obligatory) for the classes of locomotive used on passenger trains to bear names. Before 1846 diverse practices were in play; after that the majority of the names bestowed were reapplications of pre-existing proper names, for example those of persons, celestial bodies, racehorses, geographical features or buildings. This paper contends that such practices were not random, but closely aligned to sociocultural preoccupations of the period covered, 1846 to 1954, which coincides with Britain’s peak as a world power. Evidence is presented that the major railway companies differed in detail in their practices, but that there was a common overarching unscripted policy regarding eponyms which responded to contemporary high culture, moral and political values and the underpinnings of Britain’s imperial project.
Managing Onoma, the Journal of ICOS: A Multidisciplinary Approach
Authors: Felecan Oliviu , Bugheșiu Alina
Published: May 2024

Taking over the editorial office of Onoma in January 2019 was a great challenge, not only due to the tradition and brand behind the name, but also due to certain deficiencies which had accumulated over the years and led to considerable delay in the yearly publication of the journal. This study aims at presenting from an inside, but not subjective, perspective the complex process of managing the scientific and administrative issues that appeared while trying to bring the journal of ICOS back among the leading publications in the field. The current approach is multidisciplinary, as it involves linguistics, multilingualism, and onomastics (anthroponymy, toponymy, commercial names, etc.), management, economy, marketing, IT, and philology. The above-mentioned endeavour could not be achieved without the activity of a well-coordinated, competent team, determined to overcome obstacles and careful not to interfere with the high-standard peer review of the studies by the scientific committee or the overall quality of the journal. The ultimate goal consists not only of reinstating Onoma in the scientific network of onomastic publications, but also of ensuring better international visibility for the journal, which would enable its being indexed by the most prestigious databases and having a bigger impact factor.

This research aims to investigate the scientific creativity of 9th grade students following the implementation of a project-based learning (PjBL) approach. The study involved a sample of 21 students from a high school in a Roi Et province during the first semester of the academic year 2023. Participants were randomly selected using classrooms as the sampling units. The research employed a pre-experimental design, specifically a one-group pretest-posttest design. The research tools included: 1. PjBL plans. 2. Assessment of scientific creativity. 3. Satisfaction questionnaire. Data analysis involved the use of means, standard deviations, and the dependent t-test statistic. It was discovered that students' scores on creative scientific thinking after the intervention were significantly higher than before, with statistical significance at the 0.05 level. Additionally, students expressed satisfaction after participating in the PjBL, with an average rating of 4.50, falling within the criteria for a high level of satisfaction.
Difference in Literacy between Private and Public Schools: Evidence from a Survey of 61 Economies
Authors: Cheema Jehanzeb Rashid
Published: May 2024

Recent research in the United States suggests that student performance differences between private and public schools disappear once student and school level characteristics are controlled for. This is an important result as it suggests that in the absence of such differences delivery of education through public means can be as efficient as that through private means. However, given the often significant variation in economic, social, and political systems across countries, generalization of recent U.S. results to the rest of the world may not be appropriate. The current study bridges this gap in the literature by examining the private versus public school difference in literacy in key areas such as mathematics, reading, and science using recent comparable nationally representative samples from 61 economies. Our findings suggest that most economies have significant private-public school performance gaps, and for many economies these differences persist even after controlling for student and school level characteristics such as age, gender, grade, socioeconomic status, disability status, school size, and student-teacher ratio. Implications are discussed.
Explicit Incorporation of the Nature of Science (NOS) in an Undergraduate Preservice Teacher Science Content Course: Action Research
Authors: Namakula Esther Kataate , Akerson Valarie L.
Published: May 2024

This study aimed to address the gap in an environmental science undergraduate course by investigating the impact of explicitly integrating the Nature of Science (NOS) into the instruction of scientific inquiry.  The lab-based course focused on developing an understanding of the natural world, as well as the processes scientists use to study that world.  Through action research, data collection methods included the Views of Nature of Science Questionnaire (VNOS-B) and analysis of students' reflections on assignments and open inquiry projects for 37 students. Pre- and post-questionnaires were analyzed using NVIvo12, categorizing responses into five levels of NOS understanding thematically. Descriptive statistics were used to assess NOS views. Class reflective assignments and open inquiry projects were coded and evaluated using the revised NSI rubric employing a mixed methods analysis. The results reveal a notable shift in students' NOS understanding following the intervention which demonstrates the significance of deliberate NOS instruction. The research also pinpoints areas where students require focused instruction, offering valuable insights for educators with an emphasis on the impact of NOS integration in enhancing scientific literacy and highlighting the role of action research in refining instructional practices.
The Effect of Color-Filtered Lighting in the Context of Biophilic Design for Early Childhood Learning Environment
Authors: Suh Junghwa , Park Elizabeth
Published: May 2024

This research investigates the influence of color-filtered lighting in relation to biophilic design, specifically within the preschool learning environment where design elements impact early childhood development. Among various architectural design components, research underscores the pivotal role of lighting in affecting children’s pleasantness and energy levels. The experiment yielded three key findings: (1) discernible differences in pleasant and energy levels were observed between existing white lights and specific color-filtered lights; (2) varying pleasant and energy levels were noted among different color-filtered lights; (3) a relation was identified between external conditions (confounding variables) and pleasant and energy levels in the context of color-filtered lights. Subsequently, the study delved into the interplay between the effects of color-filtered lighting and natural light, specifically focusing on the Correlated Color Temperature (CCT) level. There is an opportunity to refine and innovate lighting elements of learning environments through the interplay between indirect experience elements of biophilic design, attention restorative theory (ART), and perceived emotional experience. The study offers valuable insights into the relationship between specific lighting conditions and elevated energy and pleasantness levels suggesting a meaningful avenue for further research and practical application in educational settings.

Background: The neonatal period is an individual adaptation with a higher risk of death and complications. Using parenteral nutrition to meet nutritional imbalances in neonates requires close supervision to prevent complications caused by inappropriate administration.
Objective: This study aims to examine the effectiveness of parenteral nutrition (PN) in weight changes, patient caloric balance, osmolarity, and side effects.
Methods: This study used a prospective observation method and was carried out from April to June 2023 at Universitas Airlangga Hospital. Data were obtained through medical records and direct observation of the patient’s condition after the patient’s parents signed an informed consent. Data analysis was carried out descriptively.
Results: PN was given centrally or peripherally to 71 patients. Of those, 21 were low birth weight patients. Caloric balance was achieved in almost all patients. All patients gained weight, although only 20.89% experienced a return to birth weight. Phlebitis occurred in 35.22% of patients.
Conclusion: Parenteral nutrition is efficacious in increasing the patient’s weight, depending on the suitability of the calculation between calories needed and calories obtained and the osmolarity of the preparation.
Yapay Zekâ Haberleri Aracılığıyla Medyada Distopyanın İnşası ve Hegemonik Etkileri: ChatGPT Özelinde Yaygınlaşan Korku Söylemi Üzerine Bir İnceleme / The Construction of Dystopia in the Media through Artificial Intelligence News and Hegemonic Effects: An Analysis on the Spreading Fear Discourse Specific to ChatGPT
Authors: Kaprol Aslı
Published: May 2024

Son yıllarda yaygınlaşarak hayatımızın birçok alanında önemli rol oynamaya başlayan yapay zekâ teknolojisi, otomasyon, sesli asistanlar, veri analizi ve diğer birçok uygulama sayesinde insanlara yardımcı olan bir araç haline gelmiş olsa da özellikle ChatGPT’nin hızlı gelişimi ile mesleklerin geleceğine yönelik spekülasyonlar da artmaya başlamıştır. Yapay zekâ teknolojisinihaberlerde, özellikle iş kaybına yönelik risklerle ilgili endişe tonu yüksek söylem dili kullanıldığı gözlemlenmektedir. Yapay zekâ teknolojileri ile ilgili haberler genellikle insanların işlerini kaybetme, gizlilik endişeleri, etik sorunlar ve hatta potansiyel bir yapay zekâ isyanı gibi korku unsurlarını vurgulamakta ve bu korku söyleminin toplumda belirli bir görüşü kabul etmeye ve bu teknolojilere karşı duyulan korku ve güvensizlik hissini pekiştirmeye yönelik hegemonik bir etkiye yol açma ihtimali söz konusu olmaktadır. Bu çalışma, medyada yer alan yapay zekâ haberlerinin oluşturduğu korku söyleminin hegemonik etkilerini, bilgi aktarımından sosyal algılamaya ve egemenlik ilişkilerine kadar geniş bir perspektiften değerlendirmeyi amaçlamaktadır. Çalışmada, yapay zekâ uzmanlarının medyada yer alan açıklamaları söylem analizi yöntemi çerçevesinde değerlendirilmekte ve ağırlıklı olarak yapay zekâ teknolojisinin potansiyel risklerini içeren korku söylemi yüksek haberlerin hegemonik etkileri ve olası sonuçları Gramsci’nin düşünsel yaklaşımı bağlamında tartışmaya açılmaktadır. Özellikle ChatGPT’nin teknoloji alanındaki büyük sıçramasıyla paralel olarak medyada yer alan yapay zekâ haberlerinin içeriklerinde yoğunlukla ‘Tehlike’ ve ‘Korku’ söylemlerinin yer alması neticesinde, toplumun yapay zekâ teknolojilerine karşı olumsuz bir tutum geliştirerek yapay zekânın potansiyel faydalarına karşı önyargı oluşması ihtimali değerlendirilmektedir. Çalışma, ancak bilinçli bir toplumun, medya içeriklerini ve haber analizlerini eleştirel bir yaklaşımla değerlendirebileceği ve teknolojik gelişmelere daha objektif bir bakış açısıyla yaklaşabileceği noktasından hareketle, medyada yer alan yapay zekâ haberlerinin oluşturduğu korku söyleminin etkilerini azaltmaya yönelik toplumun daha yüksek bir bilinç düzeyine ve medya okuryazarlığına ihtiyacı olduğu konusuna dikkat çekmektedir.

Published: May 2024

İnternet kullanımının hızla yaygınlaşması, sunduğu imkânların yanında sağlık açısından bazı sorunların ortaya çıkmasına neden olmuştur. Bunlardan en belirgini, kullanıcıların sürekli ve tekrarlayan internet kullanım isteğidir. Bu istek bir hastalık ya da bir bağımlılık olarak tanımlanmasa da 2014 yılı itibari ile bazı semptomları olan bir bozukluk olarak kabul görmüştür. İnternet bozukluğunun, nörobiyolojik bir davranışsal bağımlılık olduğuna yönelik çeşitli araştırmalar da literatürde yer edinmiştir. Pontes ve Griffiths (2017) internet bozukluğunun kullanıcılarda oluşturabileceği psikiyatrik semptomları betimlemek için “Internet Disorder Scale/IDS-15” isimli ölçeği geliştirmiştir. Ölçek, farklı araştırmacılar tarafından farklı kültürlere uyarlanmıştır. Türkçe literatür incelendiğinde aşırı internet kullanımının kullanıcılarda oluşturabileceği etkilere yönelik bozukluk özelinde bir ölçeğin olmadığı görülmüştür. İşte bu araştırma, IDS-15’in Türkçeye uyarlamasının psikometrik analizlerinin yapılması amacıyla yürütülmüştür. Araştırmada; ölçeğin Türkçe formunun dil eşdeğerliliği, yapı geçerliği, yakınsak ve ayırma geçerliği, ölçüt bağlantılı geçerliği, güvenirliği ve madde özellikleri incelenmiştir. Araştırma; 145 kadın, 162 erkek olmak üzere toplam 307 yetişkin birey ile yürütülmüştür. Analizler sonucunda, ölçeğin İngilizce ve Türkçe formları arasında dil eşdeğerliğinin olduğu belirlenmiştir. IDS-15’in faktör yapısı DFA ile test edilmiştir. Analiz sonucunda Türkçe ölçeğin 4 alt boyut altında toplanan 13 maddeden oluştuğu tespit edilmiş ve İBÖ-13 olarak adlandırılmıştır. İBÖ-13’ün uyum iyiliği indeksleri χ2/sd=1,364; GFI=0,963; NFI=0,957; CFI=0,988; RMSEA=0,034 şeklinde raporlanmıştır. Elde edilen AVE ve CR değerleri ölçeğin yakınsak geçerliği ile ayırma geçerliğine de sahip olduğunu göstermiştir. İBÖ-13’ün tamamı için Cronbach’s Alpha katsayısı 0,88 olarak hesaplanmıştır. Bu katsayı alt boyutlarda sırası ile 0,76; 0,84; 0,75; 0,87 olarak saptanmıştır. Bu değerler İBÖ-13’ün yeterli düzeyde iç tutarlılığa sahip olduğunu ve güvenilir bir ölçme aracı olduğunu ortaya koymuştur. İBÖ-13’ün ölçüt bağlantılı geçerlik analizi sonucunda ölçek genel puanı ile internet kullanmaya başlama yaşı ve yaşam doyumu değişkenleri arasında negatif; haftalık internette geçirilen süre ve sosyal medya bozukluğu değişkenleri arasında ise pozitif anlamlı ilişkilerin olduğu anlaşılmıştır. Buradan hareketle İBÖ-13’ün yeterli düzeyde ölçüt bağıntılı geçerliğe sahip olduğu belirlenmiştir.

Neurodegenerative disorders are one of the most insidious disorders that affect millions around the world. Presently, these disorders do not have any remedy, however, if detected at an early stage, therapy can prevent further degeneration. This study aims to detect the early onset of one such neurodegenerative disorder called Alzheimer’s Disease, which is the most prevalent neurological disorder using the proposed Convolutional Neural Network (CNN). These MRI scans are pre-processed by applying various filters, namely, High-Pass Filter, Contrast Stretching, Sharpening Filter, and Anisotropic Diffusion Filter to enhance the Biomarkers in MRI images. A total of 21 models are proposed using different preprocessing and enhancement techniques on transverse and sagittal MRI images. The comparative analysis of the proposed five-layer Convolutional Neural Network (CNN) model with Alex Net is presented. The proposed CNN model outperforms AlexNet and achieves an accuracy of 99.40%, with a precision of 0.988, and recall of 1.00, by using an edge enhanced, contrast stretched, anisotropic diffusion filter. The proposed method may be used to implement automated diagnosis of neurodegenerative disorders.

Objetivo: Seleccionar microorganismos nativos con capacidad degradativa de fármacos antiinflamatorios no esteroideos (Naproxeno, Paracetamol, Ibuprofeno y Diclofenaco) y fármacos psicotrópicos (Carbamazepina, Alprazolam y Clonazepam) a partir de aguas residuales. Material y Métodos: Este estudio examina la degradación de microorganismos en aguas residuales frente a fármacos antiinflamatorios y psicotrópicos en Lima. Se recolectaron muestras, se realizaron diluciones y se sembraron en placas. Tras verificar colonias, se evaluó la capacidad degradativa midiendo la turbidez y absorbancia a 600 nm en un espectrofotómetro. Resultados: Se analizaron colonias bacterianas destacando características como color blanco, forma circular, borde entero, textura lisa, tamaño mediano y predominio de bacterias grampositivas. Se evaluaron fármacos antiinflamatorios y psicotrópicos, observándose respuestas específicas de microorganismos. La turbidez en los tubos indicó crecimiento bacteriano, con turbidez mediana (++) para AINEs y mayor turbidez (+++) para psicotrópicos. Cepas bacterianas mostraron capacidad variable para degradar fármacos, destacando aquellas con absorbancia mayor a 1, evidenciando crecimiento por fármacos como fuentes de carbono. Conclusiones: Se hallaron microorganismos con gran potencial para degradar fármacos en aguas residuales.

La falta de una matriz de trazabilidad estandarizada tiene varias desventajas para el proceso de desarrollo de software. En primer lugar, sin una matriz de trazabilidad estandarizada es difícil garantizar la calidad y la integridad de los requisitos. Según [5], la trazabilidad de requisitos es necesaria para garantizar que los requerimientos están completos, coherentes y no redundantes. Sin una matriz de trazabilidad estandarizada, los desarrolladores pueden perder de vista los requerimientos originales y hacer cambios no justificados o que no están en línea con los objetivos por una gestión del cambio en el proyecto. De acuerdo con [6], la trazabilidad de requerimientos es esencial para gestionar el cambio en el proyecto, ya que permite a los desarrolladores identificar qué requerimientos se ven afectados por un cambio y cómo se relacionan con otros requerimientos. Sin una matriz de trazabilidad estandarizada, los cambios pueden ser difíciles de gestionar y pueden tener un impacto negativo en el proyecto en su conjunto. Por lo anterior, se realiza la Revisión Sistemática de la Literatura (RSL), se analizan las diferentes propuestas de autores o empresas sobre la Matriz de Trazabilidad de Requisitos (RTM) y se identificar los puntos débiles y fuertes de cada una, con la finalidad de proponer una RTM unificada a partir de los elementos más comunes usados por las RTM analizadas, la cual esté compuesta de fortalezas que abonen a la calidad e integridad de los requisitos.

Artificial Intelligence is one of the current generation’s inventions that has been widely used. It has helped make lives easier, especially regarding appliances and business, and it has also altered various industries, including the arts. However, this development has sparked different perspectives among artists and non-artists. This study aims to evaluate how students, both artists, and non-artists, perceive the differences between real art and artificial intelligence-generated art. For this study, a total of fifty (50) students will be gathered, consisting of twenty-five (25) non-artist students from different courses and twenty-five (25) artist students from the IARFA Institute of Far Eastern University. The participants will receive the questionnaire via Messenger. The results of this study showed that the participants could differentiate actual art from AI-generated art based on their knowledge when evaluating artworks. Additionally, it demonstrates that artist students showed more confidence in determining actual artworks from AI-generated artworks due to their knowledge. While non-artists remain skeptical in determining artworks as they base their perception on how they see art.

Authors:   National Academy of Public Administration, Vietnam, Nguyet Dinh Thi
Published: May 2024

This study explores the dynamics of gender discrimination in the workplace through the qualitative narratives of 30 Vietnamese women across various professional sectors. Using a purposive sampling method, the research employs semi-structured interviews to gather in-depth insights into the participants' experiences, which were analyzed through thematic analysis. Key findings reveal prevalent workplace gender discrimination, characterized by subtle biases, traditional gender role enforcement, and challenges linked to maternity and career advancement. These issues manifest through both overt marginalization and covert devaluation of women's professional contributions, highlighting the resilience and coping strategies women employ to navigate such environments. While the study focuses on formal employment sectors and may not capture all employment types in Vietnam, it provides valuable perspectives for policymakers and organizational leaders aiming to mitigate gender disparities. Recommendations include enhanced diversity training, transparent career advancement policies, and improved work-life balance support. This research contributes original insights into the complexities of gender discrimination, emphasizing cultural specifics that influence workplace dynamics in Vietnam.
