INVESTIGATING THE PERFORMANCE INDICES OF YOLO MODELS IMPLEMENTED ON A DPU: A COMPARATIVE ANALYSIS
Authors: GRIGORYAN M.T.
Published: February 2024

A comprehensive analysis of the performance indices achieved by implementing various “You Only Look Once” dataset (YOLO) models on a dedicated Deep Learning Processing Unit (DPU). YOLO models are renowned for their real-time object detection capabilities, making them a good choice for a range of applications including autonomous vehicles, surveillance systems, and robotics. In this study, the YOLO models are deployed onto a specialized hardware accelerator, specifically a DPU, to assess their inference speed, accuracy, and power efficiency. By conducting an in-depth comparative evaluation of multiple YOLO variants, including YOLOv3, YOLOv4, YOLOv5, YOLOv6 insights into how each model interacts with the DPU architecture are revealed. The experiments involve benchmarking these models across diverse datasets and varying hardware configurations. The results not only highlight the advantages and limitations of employing DPUs for YOLO-based applications but also help in choosing the most suitable model-DPU combination based on specific performance requirements. This study contributes to the optimization of real-time object detection systems and assists practitioners in making informed decisions regarding the model and hardware selection.

Introduction: SARS-CoV-2 began in 2020 and caused important changes in the number of transplants performed in hospitals and in the protocols for admitting candidates to perform the procedure. The Brazilian Association of Organ Transplantation (ABTO) recommends not performing transplants from donors with active COVID-19 infection, positive test results or with Severe Acute Respiratory Syndrome. The hepatic repercussions related to COVID-19 are presented in some reports in the medical literature. Liver changes resulting from other corona viruses such as SARS-CoV and MERS-CoV are well documented. The Hospital de Clínicas of the State University of Campinas is a tertiary center that performs solid organ transplants. Objectives: To carry out a perioperative, retrospective, descriptive analysis of liver transplants in the context of the SARS-CoV-2 pandemic carried out at the Hospital das Clínicas of the State University of Campinas from March 2020 to July 2021. Materials and Methods: Retrospective, descriptive, longitudinal cohort study based on the review of medical records of patients undergoing liver transplantation in the context of the SARS-CoV-2 pandemic from March 2020 to July 2021 at the clinical hospital of the State University of Campinas. Results:Retrospective analysis was performed on 57 patients in the period. Only 1 patient needed to be excluded because he was under 18 years old. Of the 56 patients, 52 underwent RT-PCR laboratory testing and chest tomography (CT). Of these 52 patients, only 2 tested positive, one pre-transplant (TX) and one post-operatively (post-op). Regarding chest CT scans, none of them showed typical changes for COVID pre-TX, in the post-op 4 patients presented typical chest CT scans. The average age was 55.86 years. The mortality rate was 38% and no deaths were attributed to COVID 19. The average MELD-Na scale was 20.94. Conclusion: The present study carried out at the Hospital de Clínicas da Unicamp analyzed the clinical, laboratory and radiological association to better elucidate the variables determined by COVID-19 in its diagnosis and in-hospital management. It is concluded that the SARS-CoV-2 pandemic had an impact on the routine of liver transplantation worldwide and on the service in which the study was carried out.

Published: February 2024

This paper aims to present the main results of the Master's research, developed in the Graduate Program (Professional Master's Degree) in Field Education - UFRB. The present research sought to analyze the vocational training of young people from the fields of the Dom Fragoso EFA and its consequences on productive and political insertion in their rural communities, in the region of Inhamuns/Crateús. It is a qualitative research, the collection of data by applying an online questionnaire with 37 young people who have come back and carrying out 08 semi-structured interviews. The results of the research indicate that they are young people from the countryside, sons and daughters of rural workers, the first of their families to have concluded high school and to have gone into higher education. The majority of them migrated to the medium and large urban centers of the state, in search of work or for continuity of studies in higher education, however, it is evident the strong feeling of belonging of young people returning to their territories of origin. Finally, the importance of the political training obtained by the young people who have returned to the Dom Fragoso TASK, expressed in their active participation in social organizations and movements and in the struggle to conquer the right to remain in the field, is highlighted.
Educational actions in cultural spaces and their links with concepts of aesthetic education and cultural mediation
Authors: Costa Denise , Uriarte Mônica Zewe
Published: February 2024

This article aims to outline links between educational actions of cultural spaces with concepts of aesthetic education and cultural mediation. Pointing to a bibliographical investigation, of a qualitative approach, as a methodology, we opted for the use of cartography, which proved to be appropriate for the possibility of expanding and multiplying research paths. The choice of mapping methodology is based on Deleuze and Guattari (2019) and Passos, Kastrup and Scotland (2020). We research on cultural institutions in Brazil to identify the characteristics and type of educational actions they offer, as well as the availability of digital materials. Recognizing the existence of a significant number of materials, we find that interested parties need to seek the information. We emphasize the importance of research into these materials by teachers, to promote students' contact with art and culture. We emphasize the importance of this research with regard to the articulation of educational actions of cultural institutions, which through their materials make possible encounters of students from various regions of the country with art. In this sense we understand that the teacher mediator, who researches and shares this knowledge allows his students to make an experience with art. We sought theoretical input for the concept of aesthetic education in Schiller (2013), on the concept of cultural mediation in Martins (2012), Heidegger (2003) assured us the concept of doing an experiment, Rancière (2015), (2017) supported emancipation, among other important authors. As a result, we understand that cultural spaces that offer possibilities to expand dialog, poetic exercise and the perspective of aesthetic education through educational actions, promote opportunities for encounters with art. In the dialogical and poetic exercise of the subject with art the subject plays and moves reason and emotion, which makes it possible to make an experience and educate aesthetically. We emphasize the importance of the teacher researcher and mediator, who is a proponent, who provokes and challenges students to dialog with works of art, activating the playful impulse in the subject, so that he can make an experience on the way to aesthetic education.
Bobbio's conception of human rights
Authors: Caprioli Efraim , Nunes Flavia Carrijo , Nieddermeyer Henrique Lacerda
Published: February 2024

This article aims to analyze the issue of human rights in the thinking of the Italian author Norberto Bobbio. The historical and contemporary debate on human rights has always been a scene of considerable controversy, gaining considerable space in the public debate with the advent of the Second World War, culminating in the signing of the Universal Declaration of Human Rights (1948). This declaration intended to meet a minimum set of rights so that every human being deserves, from birth, as a member of the human species. For the recognition of these rights universally, there is a need for this set of rights to correspond to the desires of all people, with their different cultures. In order to establish consensus, therefore, it is necessary to find homeomorphic concepts of human rights in different cultures. A second problem involving human rights is the issue of their protection, which is difficult to apply in certain cultures. In this second problem, Bobbio’s thought seems to have space, which identifies the effectiveness of human rights as the biggest challenge in this issue, especially regarding the rights of freedom and equality. The present study is based on exploratory research, with bibliographic analysis based on data collection in updated scientific material on the topic.

Soy and coffee crops hold significant economic importance in Brazil and worldwide. Nickel (Ni), recently discovered as an essential micronutrient for plant development, leads to underreported soybean and coffee crop effects following foliar applications. In this sense, this study aimed to conduct a bibliographical survey employing the Google Scholar database and specialized websites concerning foliar Ni soybean and coffee crop applications. Foliar spraying is noted as more effective in supplying Ni to these crops compared to soil application, with both positive and negative effects identified. On the one hand, this micronutrient can aid in urease reactions, although, on the other it may lead to phytotoxicity, reducing crop yields, and resulting in environmental contamination if improperly applied. Reports concerning soybean are limited to Ni soil and seed applications, despite the proven benefits of foliar spraying. With regard to coffee, most studies focus on C. arabica, probably due to its more extensive cultivation compared to C. canephora. Further research is, therefore, paramount in unravelling the role of Ni in grain and fruit yields, particularly in coffee crops.
Depression and anxiety levels among patients with thyroid disorders: A cross-sectional study
Authors: Karagun Baris
Published: February 2024

The aim of this study was to investigate the association between anxiety and depression among patients diagnosed with different thyroid disorders, as well as to identify the frequency of these comorbid conditions. A total of 181 (female/male; 142/39) patients with different thyroid diseases were assessed in this cross-sectional study. Patients were classified according to the type of thyroid disorder they were diagnosed with. The biochemical parameters were obtained from hospital database. The Beck Anxiety Inventory (BAI) and the Beck Depression Inventory (BDI) were utilized to evaluate the association between thyroid disorders and anxiety/depression among patients. Upon classifying patients according to their thyroid disease, it was found that 24 patients (13.2%) were diagnosed with non-autoimmune hypothyroidism, 40 (22.1%) with autoimmune hyperthyroidism, 85 (47%) with autoimmune hypothyroidism, and 32 (17.7%) with nodular thyroid disease. The average scores for BDI and BAI were 15.50±10.19 and 17.83±12.01 in the whole study group. Anxiety and depression were both quite common among patients, with respective rates of 75.7% and 66.7%. BDI scores were significantly correlated with the levels of anti-TPO and anti-TG in patient groups with autoimmune thyroid diseases. Additionally, there was a significant correlation between the BAI scores and anti-TG levels. Patients with thyroid disorders in this study frequently have high levels of anxiety and depression. There is a relationship between depression and anxiety and the levels of thyroid autoantibodies. The presence of thyroid autoantibodies may be a sign of susceptibility to depression and anxiety in thyroid patients.

En esta nota se lleva a cabo un análisis de la frecuencia, participación y las jornadas no trabajadas en huelgas durante el periodo 1987-2006, relacionándolas con la distribución sectorial del empleo, la tasa de paro, la existencia de pactos y acuerdos regionales y la orientación política de la población. Las regresiones muestran la influencia de todos estos aspectos sobre la frecuencia, la magnitud y el volumen de huelgas.
La globalización de los movimientos sociales y el orden liberal. Acción política, resistencia cívica, democracia
Authors: Arias Maldonado Manuel
Published: February 2024

Así como la configuración predominantemente estatal de la política tuvo en su centro a la movilización colectiva nacional, la emergencia de los movimientos sociales transnacionales está contribuyendo decisivamente a la redefinición contemporánea de la política posnacional. De hecho, no puede afirmarse simplemente que la mundialización haya producido formas transnacionales de acción colectiva; la propia mundialización es, en parte, la consecuencia de una temprana transformación de la movilización social. Sea como fuere, no parece que la teoría política haya respondido todavía adecuadamente al tránsito de unos movimientos nacionales, instalados cómodamente hasta ahora en el familiar marco del Estado-nación, a unos movimientos transnacionales que no responden a un contexto institucional tan definido. Este artículo trata de arrojar luz sobre la naturaleza de estos novísimos movimientos transnacionales, con especial atención al movimiento antiglobalización y una vocación explicativa de sus relaciones con el orden político liberal.

Published: February 2024

Churches and religious societies, despite the suppression of their importance, mission and results of their pastoral and educational activities in Slovak society since the second half of the 20th century and their temporary radical revival after 1990, are in the currently ideologically enforced corporate-liberal social environment again subject to recognition, condemnation and suppression. It also applies to their representatives, their believers, their membership base. It is obvious that, on the basis of the ecumenical program born during the Second Vatican Council, even in Slovak society, the dominant Roman Catholic Church has clearly stepped out of its historical socio-paternalistic attitudes. The current policy of the Slovak particular Roman Catholic Church leads all its members and adherents to religious tolerance. Despite this, manifestations of religious tolerance in the current secularizing Slovak national community are accepted by a certain part of the so-called modernist population with a considerable amount of animosity. This opens up a vast and fragmented political space for the Slovak state authorities to regulate and eliminate the currently more aggressive manifestations of the currently living intolerance. Especially radically directed against the views of the "backward", so-called the worldview of the archaic, i.e. religiously oriented, majority of the Slovak population. The task of the current state power becomes the reduction of anti-religious and anti-church activities, rooted in and based on a destructive ideological and ideological platform that negatively affects the value orientation of the emerging West European so-called liberal-modernist generation.

New Ratio Estimators for Population Mean under Unequal Probability Sampling Without Replacement in the Presence of Missing Data: A Case Study on Fine Particulate Matter in Bangkok, Thailand
Authors: Ponkaew Chugiat , Lawson Nuanpan
Published: February 2024

Missing data are frequently present in datasets and give rise to a myriad of issues that significantly affect data utilization. The missing data needs to be handled before data can be efficiently estimated and applied. New ratio estimators for population mean were proposed for use when data are missing completely at random and for a more flexible situation where missing data are missing at random in the study variable under unequal probability sampling without replacement. Furthermore, the variance estimators of the proposed ratio estimators were investigated under a reverse framework.  We show theoretically that the proposed estimators were approximately unbiased estimators. The proposed estimators were utilized in simulation studies and were applied to the study of fine particulate matter data in Suan Luang District, Bangkok, Thailand in order to see how the proposed estimators performed. The results from the application to fine particulate matter showed that the ratio estimators and their variance estimators worked better than existing estimators, producing less estimated variances. Therefore, they could be applied to estimate the average fine particulate matter even when missing values appeared.
A Security Aware Channel Assignment Protocol for Software Defined Networks
Authors: Mahajan Yash , Vyas Dr. Manish
Published: February 2024

Software Defined Networks (SDNs) have a great potential in supporting time-critical data delivery among the Internet of Things (IoT) devices and for emerging applications such as smart cities and automation. A wireless channel (radio) about which we have information is called a software defined radio. However, Software defined radio Networks share common resources such as bandwidth or spectrum among several users or stations. Due to continued sharing of resources, cognitive networks often come under security attacks, most common of which are jamming attacks. In the case of jamming attacks, deliberately designed random jamming signals are added to the channel. These jamming signals along with noise result in packet losses and low throughput, degrading the overall performance of the cognitive network. In this work, a security aware jamming rejection mechanism is proposed which detects suspicious signals in the channel frequency response and employs discrete equalization to recover transmitted data. Moreover, this also reduces the effects of noise in the channel. It has been shown that the proposed system achieves higher throughput compared to previous techniques for low, moderate and high jamming activity. Keywords:- Software defined radio, Internet of Things (IoT), Jamming Activity, Energy Detection, Equalization, Throughput.

Published: February 2024

Trong bài viết này tác giả trình bày kết quả nghiên cứu ảnh hưởng của nhiệt độ và thời gian xử lý thuỷ - nhiệt đến chất lượng gỗ Dầu rái (Dipterocarpus alatus). Nghiên cứu đã tiến hành xử lý thuỷ - nhiệt gỗ Dầu rái ở nhiệt độ (160oC, 180oC, 200oC) trong 4 giờ và xử lý gỗ với thời gian (3 giờ, 4 giờ, 5 giờ) ở nhiệt độ 180oC. Gỗ trước và sau khi xử lý được đánh giá thông qua độ nhám bề mặt, hệ số chống trương nở (ASE), hiệu suất chống hút nước (WRE), độ bền nén dọc, độ bền uốn tĩnh, khả năng kháng nấm, màu sắc. Kết quả nghiên cứu cho thấy: Gỗ sau khi xử lý đã cải thiện được một số tính chất so với gỗ đối chứng. Khi tăng nhiệt độ và thời gian xử lý thì độ nhám bề mặt của gỗ xử lý giảm từ 76,44 µm xuống 66,03 µm; hệ số chống trương nở ASE tăng từ 36,93% đến 43,17%; hiệu suất chống hút nước WRE tăng từ 27,36% đến 41,79%; khả năng kháng nấm mục đạt từ mức “trung bình” đến “tốt”. Tuy nhiên, độ bền nén dọc giảm từ 48,13 MPa xuống 43,85 MPa; độ bền uốn tĩnh giảm từ 87,34 MPa xuống 81,56 MPa; độ lệch màu ΔE* thay đổi từ 28,89 đến 52,17. Như vậy, nhiệt độ và thời gian xử lý thuỷ - nhiệt có ảnh hưởng đến một số tính chất của gỗ Dầu rái. Theo kết quả nghiên cứu này, để đảm bảo chất lượng của gỗ sau khi biến tính và đem lại hiệu quả kinh tế nên xử lý thuỷ - nhiệt cho gỗ Dầu rái ở nhiệt độ 180oC trong 4 giờ là phù hợp.

Five Errors that Have Never Been Discussed Over the Theory of Special Relativity
Authors: Wu Sean Yuxiang
Published: February 2024

We discuss special relativity from the following five aspects that none of them was discussed before:

1. Einstein discussed special relativity extensively using a system that was not a relative system.

2. The synchronous transfer rule defined by Einstein is wrong.

3. The physical model (rays in inertial motion relative to a rigid rod) used by Einstein to derive the special theory of relativity was wrong, and the resulting mathematical model (Lorentz transformation, etc.) was also incorrect.

4. Countless contradictory calculation results caused by passive relativity.

5. Why did Einstein repeatedly emphasize that there is no “relative system that maintains absolute simultaneity?” Why people cannot find a relative system maintaining absolute simultaneity before? We proved countless relativistic systems maintain absolute simultaneity.

Diabetic foot infections (DFIs) represent one of the most serious and frequent complications resulting from diabetes mellitus, causing substantial morbidity as well as enhanced risk for amputation. The microbiological world of DIFs is typically multifaceted and usually includes a polymicrobial community with both aerobic bacteria this anaerobe the purpose of this review is to decompose the current knowledge about microbial diversity in DFIs, their resistance patterns and biofilms contribution for resilience towards infection persistence and therapy. Development of molecular techniques has allowed increased insight into the DFI microbiome, not only uncovering prevalent pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa but also lesser frequently isolated organisms. The employment of multidrug-resistant organisms and the intricate relationship between microbial species within biofilms present serious management challenges. The review focuses on the relevance of early and accurate diagnosis using culture-based methodologies as well molecular methods that, in turn, would enable more specific antimicrobial therapy. Moreover, the opportunity of new antibacterial agents will be available; other local delivery systems and adjunctive therapies like negative pressure wound therapy would also be addressed. Strategies of prevention that involve patient education, regular foot checks and proper glycemic control form part of essential measures in reducing incidences of DFIs. An interdisciplinary approach to care is highlighted in the review, influencing diabetology specialists, infectious disease physicians and microbiologists as well as podiatrists be able to improve treatment outcomes. This review aims to provide the most recent synthesis on microbiological aspects of DFIs and their clinical implications, with an intent of informing development of more effective strategies for management thus improving patient’s quality life as well reducing pressure from health care systems.

The state of Paraíba, specifically in the alto sertão of Paraíba, is characterized by the spatial and temporal variability of rainfall, of temperature and evapotranspiration, coming from the semi-arid climate that is inserted in the region, and yet, the performance of different meteorological systems. The objective was to quantify the rainfall, temperature and reference evaporation (mm/ month and mm/year) comprised in the experimental period between 2016 to 2020, in the municipality of Catolé do Rocha-PB, in order to determine the history of the rainy and dry season, and thus, minimize agricultural production losses due to environmental factors. The daily rainfall, temperature and reference evaporation data were obtained by means of a rain gauge and the indirect method of the class A tank, respectively. The rainfall (mm year-1) was analyzed by the nonparametric Friedman test, the Conover test and reference evaporation (mm year-1) applied the parametric test of the ANAVA and the test of Tukey HSD. Both parametric and non-parametric tests were analyzed by Real Statistics. Temperature data was compiled from the website (www.inmet.gov.br) in order to control, statically collecting and decision-making in the process of building scientific knowledge regarding meteorological data (climate - Temperature). Were also analyzed pearson's correlation matrices and elementary principal components analysis for the rainfall variables, Eto and Temperature in the studied experimental period. Were also studied the principal component analysis between the years 2016 to 2020 and its significance by the t test. The average reference evaporation between 2016 and 2020 was 2.1 times greater than rainfall. Mean rainfall and reference evaporation in Catolé do Rocha-PB between 2016 and 2020 were 827 mm ano-1 and 1704 mm year-1 and are compatible with historical averages of 800 mm year-1 and 1700 mm year-1, respectively.

Contemporary education requires educational proposals that include digital practices and tools to encourage reading and writing. The objective of this article is to analyze the applicability of the Luz do Saber platform as a Digital Educational Resource (RED) that facilitates the literacy and literacy processes of students in basic education. The methodology is qualitatively based and uses bibliographical research with consultation of government websites – related to programs, projects, digital educational resources and experience reports – to verify its applicability aimed at literacy and literacy – especially Luz do Saber. The results indicate that Luz do Saber as a RED contributes to the literacy of students with its gamified, playful, interactive activities and immediate feedback. The deficient digital teaching training and aspects relating to the infrastructure of institutions and the democratization of the internet are some issues of great impact on the effective use of RED.

The sustainable school arises from the need to rethink a new school and reflect on the future of humanity, with regard to concepts that have not been explored so far. It highlights the concepts of the idealized system for creating sustainable environments, involving socio-economic, environmental and ethical areas. The aim of this work is to analyze the use of these new information technologies, or ecotechnologies, in the implementation and maintenance of sustainable schools, in order to elucidate the latest discoveries in this area. In addition to carrying out a bibliographical review on the subject, it measures the possibilities for its use in a practical and objective way. The methodology used was bibliographical research on the subject in question, breaking it down through a qualitative approach, using scientific articles and more recent works considered to be the most relevant in the field of ecology and sustainability, with a focus on the implementation and use of technologies aimed at environmental education in schools. It was concluded that the use of new information technologies, or ecotechnologies, whether they are social communication technologies or not, in the context of implementing and maintaining sustainable schools, although paradoxical, is necessary in order to develop viable solutions and/or alternatives to an unavoidable social reality, especially for new generations and students. It should be noted that integrating multimedia information technology into environmental education and, consequently, into sustainable schools, raises students' awareness and knowledge of different environments and encourages the dissemination of new possibilities despite the existing distance.
