Background. Sepsis is a life-threatening condition in response to an infectious agent, causing damage to organs. Sepsis causes serious consequences in neonates due to high rates of mortality, sequelae, and disability. The Southeast Asian country of Vietnam features on of the highest infectious disease rates in the world (high rates of infection, disability and mortality), as well as being a middle-income country with a stratified health care system. The aim of this study was to evaluate the clinical and laboratory characteristics of patients at the Vietnam National Childrens Hospital. Materials and methods. This descriptive study was conducted with 85 full-term infants with sepsis admitted to Vietnam National Childrens Hospital in the period from December 2019 to April 2021. Patients had at least 2 clinical symptoms and 2 laboratory signs according to the criteria for assessment of neonatal sepsis (European Medicines Agency in 2010) along with positive blood culture results. Results. Common clinical symptoms in neonates with sepsis included poor feeding (89.4%), respiratory failure (69.4%), fever (51.8%), tachycardia (52.8%), and shock (25%). Anemic patients accounted for many (72.9%). Patients with increased white blood counts accounted for 41.2%. Newborns with a low white blood count accounted for 15.4%. Patients with thrombocytopenia were 49.6%. Most patients had elevated CRP (88.3%). The mean value of nCD64 was 10167.16136.9 molecules bound/cell. mHLA-DR was 9898.414173.9 molecules bound/cell. The Sepsis Index was 274.6287.5. Conclusions. We recorded differences in clinical characteristics and laboratory tests in full-term neonates with sepsis at National Childrens Hospital, of which, nCD64, mHLA-DR, and Sepsis Index should be further investigated and referred to as prospective routine biomarkers in diagnosis of neonatal sepsis.

Published: March 2023

The growth of the aquaculture sector leads to a demand for sustainable feed ingredients. Prebiotics are potential sustainable feed ingredients that can promote the improved performance of aquaculture species without the use of antimicrobials. This study investigated the potential of Azolla pinnata as a candidate prebiotic source. Prebiotic characteristics and dietary effect of commercial diet (CD) with varying pulverised azolla (PA) inclusion was evaluated. Results showed that PA (9.40% moisture) constitutes around 16.1% ash, 22.3% crude fibre, 20.9% crude protein, 1.7% crude fat and 29.6% nitrogen-free extract. Crude xylan and cellulose content of PA were 13.7% and 12.6% dry matter (DM) respectively. Growth of Lactobacillus rhamnosus in PA-supplemented MRS broth remarkably improved after 4 to 6 hours of incubation. Feeding trials results revealed that PA inclusion had no adverse effect on average survival of milkfish fingerlings, albeit significant improvement (p < 0.01) was noted in group fed with 2% PA-replaced CD in terms of the total weight gain (119.9%), specific growth rate (2.62% day–1) and feed efficiency (79.9%). The present study demonstrated the prebiotic activity of PA, as well as its potential use as dietary feed component for improved growth and feed efficiency of cultured milkfish.
Socio-cultural preconditions for the cult of aggression and destructive processes among young people
Authors:   Altai State University, Detkov Alexey P. , Starodubtseva Maria A. ,   Altai State University
Published: March 2023

The article analyses the socio-cultural preconditions of the cult of aggression and destructive processes in the modern youth environment. The authors point out that the ongoing global hybrid war of information is using the levers of mass culture for its own purposes. The Internet has become one of its main spokespeople and its main advantage - the high speed of spontaneous dissemination of information. In essence, it is about the purposeful formation of a new type of terrorist by the ideologists of terrorist organizations through the distortion of consciousness and worldview. Further the authors specify the marked chronological sequence of application to Russian youth of technologies of management of masses from 2014 to 2021. Such technologies have been organically incorporated into mass Internet culture, not least because of the new ideal of young people - the anti-hero who challenges the system and destroys their enemies exclusively by force. In society today there is a desire for individualism, for isolation. Instead of critical analysis, cliched thinking, born and bred by a crisis of ideals, dominates today. An example is the now booming genre of superhero cinema. Bright heroes in equally bright and grotesque costumes battle some alien evil, destroying half of their own world along the way. It's a dumbing down of sensuality, a domination of form over content, a cliched shell that hides a reverse morality of permissiveness. And this is one of the tenets of terrorist movements and destructive ideologies. In order to confirm these theses, the authors conducted criminological research aimed at identifying the causes of the distortion of the moral image of modern society and moral categories in mass culture. The relationship between the moral values of individuals and their impact on the crime situation in society was studied. The study was conducted among teachers and students of the College of Altai State University. The respondents were also teachers from the Department of Criminal Law and Criminology at the Law Institute and the Department of Social Philosophy, Ontology and Theory of Knowledge at the Institute of Mass Communication, Philosophy and Political Science. A total of 330 respondents, aged 18-25 (students), 30-45 (teachers) were randomly sampled. The results confirmed the authors' hypothesis that the cult of power propagated by the mass media provoked a spontaneous social contamination, which was met by a surge of violent acts of a terrorist nature. Hybrid confrontation between states and uncontrolled, and often encouraged, terrorist activities in the digital sphere have given rise to an aggressive ideal of the hero of our time. Combating this triad requires a solid ideological basis in the anti-terrorist sphere, created through the joint efforts of the state and civil society institutions. The authors declare no conflicts of interests.
The archetype of the national system of criminal procedure and the prosecutor as its dominant subject
Authors:   Troitsky and Novomoskovsky administrative districts of Moscow, Levchenko Oleg V.
Published: March 2023

The article proposes the author's definition and classification of primary and secondary signs of the national criminal procedural and legal organization of combating crime, as well as their manifestation in the legal status of the leading participant in pre-trial proceedings. The author concludes about the uniqueness of the modern form of pre-trial proceedings, which has become an organic part of the positive-legal criminal procedure model and doctrine. The legal organization of pre-trial and criminal proceedings as a whole is the result of balanced political forces. It is the political choice of the elite and, at the same time, an indicator of the real involvement in the political and legal processes of society. Now, a strong presidential power needs a strong accusatory power of the prosecutor's office. The investigative power must be subordinated to the power of the prosecutor: supervision over the procedural activities of investigators and bodies of inquiry is a form of prosecutor's management of law application in the pre-trial stages. The article presents a compromise concept of the investigative-prosecuting authority as the basis for optimizing the legal model of pre-trial proceedings and the entire legal system for combating crime. The specificity of the Russian investigative model of the legal organization of pre-trial proceedings is manifested in the separation of powers of two kinds: (1) the separation of the investigative-prosecuting and judicial powers and (2) the separation of the prosecutorial and investigative powers - the latter is redundant and does not correlate with the system of separation of powers in a legal state. The prosecutor and the investigator are the subjects of criminal prosecution, in relation to which the judiciary acts as a restraining force. It is the unity, not division, of the investigative and prosecutorial power in pre-trial proceedings that should be discussed. The one who conducts pre-trial proceedings with installed institutions of prosecution and evidence manages the criminal proceedings as a kind of “leading subject.” All other subjects, including the court, which is passive in the accusatory, that is, proactive plan, are followers. The prosecutor has a special position in the process, since he/she has exclusive powers regarding the transfer of a criminal case to court. The procedural role of the prosecutor has an inter-stage, general procedural character. Hence the author concludes about the superiority of the accusatory power of the prosecutor, which extends to pre-trial proceedings in relation to both the accusation and its proof. The prosecutor's office, as the accusatory power of the state, should be the central element of the criminal procedural and legal organization for combating crime. The institutes of accusation and proof, subject to the prosecutor, should form the elementary basis of the legal organization of combating crime.
Between “Glórias”: Landscapes of Forgetting in Glória Neighborhood — Rio de Janeiro
Authors: Almenteiro Domitila , Tângari Vera
Published: March 2023

The article looks at everyday public open spaces and the different forms of their appropriation in the surroundings of the short wall located in the neighborhood of Glória, in Rio de Janeiro, through a multiscale landscape analysis that identified the short wall as a landscape structuring element. The short wall is a vestige of the past, driving the ‘displacement’ and forgetting of the Guanabara Bay, while also being a remembrance of the place’s bygone waters and histories. It also works as a physical limit that conforms different spaces, occupied mainly by social groups formed by workers, transvestites and homeless people who make these spaces their place of living, working and resisting, but even so continue to be “forgotten” by society and the government. This text results from the author’s Master’s research at the UFRJ Post-graduate Program in architecture, and from her personal experiences in the neighborhood of Glória. By identifying different landscape units, evaluation criteria were defined and divided into five perspectives, making it possible to characterize the territory through different aspects that shed light on the intangible dimensions of the landscape, particularly its conflicts and contradictions. The results are presented in maps and section cuts, and summarized in an analytical chart.
IGHG1 promotes malignant progression in breast cancer cells through the regulation of AKT and VEGF signaling
Authors: Zhang Yong , Fang Xueying , Sun Yan
Published: March 2023

Immunoglobulin heavy constant chain gamma 1 (IGHG1) is highly expressed in a variety of cancers and is considered an emerging prognostic marker. Overexpression of IGHG1 in breast cancer tissues has also been demonstrated, but an in-depth analysis of its role in disease progression has not been explored. In this study, we used a range of molecular and cell-based assays to show that increased expression of IGHG1 in breast cancer cells activates AKT and VEGF signaling, leading to enhanced cell proliferation, invasion, and angiogenesis. We further show that IGHG1-silencing can suppress the neoplastic characteristics of breast cancer cells in vitro and suppresses tumor growth in nude mice. These data reveal a key role of IGHG1 in the malignant progression of breast cancer cells and highlight its potential as a prognostic marker and therapeutic target to control metastasis and angiogenesis in malignant breast tissue.

THE CORRECTING FUNCTIONS METHOD FOR SOLVING A BOUNDARY VALUE PROBLEM FOR THE AMBIPOLAR DIFFUSION EQUATION IN A DOMAIN WITH A CURVILINEAR BOUNDARIES
Authors:   Institute of Automatics, Cybernetics and Computer Engineering, National University of Water and Environmental Engineering, Rivne, Ukraine, Moroz I. P.
Published: March 2023

An approach for the ambipolar diffusion equation boundary value problem solving, which is posed in a two-dimensional domain with oscillating boundaries, is proposed. The construction of the solution of the model problem is based on the corresponding problem for a certain internal canonical majorant domain and the methodology for constructing the so-called corrective corrections based on the use of the perturbation theory elements. A feature of this problem is that it is not the problem equation or boundary conditions that are perturbed, but the region. And this leads to the construction of a fundamentally new solution structure.

The role of heme in environmentally caused oncogenesis (review)
Authors: Pinaev Sergey K.
Published: March 2023

The association of hemoblastoses, tumours of the central nervous system, with several other human neoplasms with various environmental factors of a chemical and physical nature has been previously established. Nonetheless, the mechanism of this relationship remains unclear. The author formulated the concept of environmentally determined oncogenesis with a key role of heme. According to the proposed model, the first stage of oncogenesis is the induction of environmentally determined oxidative stress, which is amplified by haem iron. Simultaneously, due to the ferromagnetic properties of heme iron reception, the induction and amplification of external electromagnetic fields occur with the formation of a feedback loop and additional stimulation of oxidative processes. Further, under the influence of active oxygen metabolites in target tissues with the greatest contact with heme, epigenomic dysregulation of semaphorin is developed. This leads to oncogenesis in actively proliferating cells of the axon growth cone, bone marrow, precursors of kidney cells, mesenchymal stem cells and endothelium. Consequently, benign tumours of the endothelium (hemangiomas), leukemias, lymphomas, tumours of the peripheral and central nervous system, as well as benign and malignant tumours of soft tissues occur. The proposed model illustrates the features of childhood oncology incidence with a predominance of hemangiomas among benign tumours, as well as hemoblastoses and tumours of the nervous system among cancers. In addition, the ability of heme to interact with electromagnetic fields advances our understanding of the relationship between neoplasms and solar activity.

The Sticky Riff: Quantifying the Melodic Identities of Medieval Modes
Authors: Helsen Kate , Daley Mark , Schindler Jake
Published: March 2023

Andrew Hughes' Late Medieval Liturgical Offices afforded chant scholarship more melodies than it knew what to do with. Until now, chant scholarship involving 'Big Data' usually meant comparing individual feasts to the whole corpus or looking at general trends with respect to 'word painting' or stereotyped cadences. New research presented here, using n-gram analysis, networks, and Recurrent Neural Networks (RNN) looks to the nature of the gestural components of the melodies themselves. By isolating the notes preceding, and proceeding from, the naturally occurring semitones in the medieval church modes, we find significant recurrence of particular phrases, or riffs, which we propose could have been used to help 'build modes' from the inside out. Special care needed to be brought to the question of assumed B-flats that were not given explicitly in the manuscripts represented in Hughes' work. Understanding modes not as 'scales' but as a collection of associated smaller musical gestures, has resulted in a set of recurring riffs that appear as the identifiers of their larger contexts and confirming the influence of an earlier, oral / aural culture on these late medieval chants where musical literacy was expected.
Beyond (the cave of) pitch/loudness-equalization: A Commentary on Reymore (2021)
Authors: Siedenburg Kai
Published: March 2023

Traditional approaches in timbre research have often equalized sounds according to pitch, loudness, duration in order to study timbral differences across instruments. In a compact case study of the semantic qualities of the oboe and French horn, Reymore (2021) takes a different approach and considers timbral differences within musical instruments, which arise due to the covariation of timbre with the musical parameters of fundamental frequency (pitch) and playing effort (dynamic level). The study constitutes a timely contribution to a growing body of work on the covariation between timbre, pitch, and loudness. After providing a background and summary of important aspects of the target article, I elaborate on results from a recent complementary study that analyzed acoustical signal properties regarding that matter. Finally, I address three important issues in this context that appear to be worthy of future research.
Geometría y dimensiones de estructuras de disyunción columnar en rocas volcánicas de Colombia
Authors: Calderón Camilo E. , Sánchez John J.
Published: March 2023

Las estructuras de disyunción columnar en rocas volcánicas corresponden al patrón de diaclasas que resulta de la contracción y deformación de los materiales durante el enfriamiento post emplazamiento. Estas pueden desarrollarse tanto en lavas como en depósitos de corrientes de densidad piroclástica (CDP) soldadas. En este estudio se analizaron visualmente 394 polígonos en 14 afloramientos de rocas volcánicas y depósitos volcaniclásticos soldados con disyunción columnar en Colombia, y computacionalmente, 349 polígonos definidos por procesamiento de imágenes. Estas medidas, junto con las variaciones relativas de tamaños de las columnas, fueron utilizadas para estimar la homogeneidad, el orden y la madurez de los patrones de disyunción. La relación entre tamaños de estrías y longitud de lado de columnas se usó para aproximar el mecanismo de disipación calórica dominante durante el emplazamiento de lavas y CDP. La inspección visual de afloramientos reveló que en lavas domina la geometría hexagonal, mientras que en depósitos de CDP dominan los pentágonos y tetrágonos. El análisis computacional indica que, en general, la disyunción columnar en Colombia tiende a organizarse en geometría hexagonal óptima. Específicamente, el afloramiento denominado Cristales, ubicado en el flanco suroriental del Nevado del Ruiz, en la cordillera Central, presenta el mayor grado de madurez; el Domo Victoria, un volcán monogenético de la cordillera Central, tiene el mayor grado de homogeneidad; y el sitio Los Ataúdes, ubicado en el flanco occidental de la cordillera Occidental, muestra el mayor grado de ordenamiento. Las estrías usualmente están entre 10 y 25% del lado de columnas. Los valores del número de Péclet entre 0,28 y 0,41 indican que en el emplazamiento de las lavas dominó la transferencia de calor conductiva, aunque no se puede descartar la disipación de calor convectiva asistida por diaclasas.
Mineralogical, petrographic, and geochemical analyzes which confirm the hydrothermal origin of the sediments that overlie the peridotites of Cerro Matoso, Colombia
Authors: Castrillón Andrés , Lartaud Franck , Delgado-Huertas Antonio , Núñez-Useche Fernando
Published: March 2023

The Cerro Matoso deposit, one of the largest open-pit ferronickel mines in the world is formed by a sedimentary succession on top of an abducted ultramafic body that makes part of the Cauca ophiolite complex. The set of rocks was accreted in northwestern Colombia during the Cretaceous and exposed to weathering processes during the last Andean Orogeny. Sediment samples were collected and studied using petrographic microscopy, SEM, EPMA, ICP-MS, XRF, and oxygen as well as carbon isotopes analyses. Oxygen isotope results reflect pore-water temperatures reaching up to 130°C during mineral precipitation, which are consistent with serpentinization-derived fluids of mantle rocks that may be related to deep-sea hydrothermal activity. Negative δ13C values (–27.1 to –1‰ V-PDB) in bulk samples of the tabular succession correlate with the δ13C range of methane from modern serpentinite-derived fluids. The REE/Fe data (ratio <0.4) suggest that sediments differenced in black mudstone and fossiliferous green claystone correspond to metalliferous and hydrothermal sediments respectively, formed in the ancient mid-ocean Pacific ridge, far west of its present position. Positive Eu and negative Ce anomalies registered in the black mudstone succession correlate with a hydrothermal plume scenario.
Mineralogical analysis of a residual soil from Medellín Dunite (Colombia) and its influence on physical properties and unsaturated undrained shear strength
Authors: Meza-Ochoa Victoria , L. Morales Álvaro , Márquez-Godoy Marco Antonio
Published: March 2023

The residual soils have a physical-mechanical behavior that reflects their formation process. In the present work, a residual soil derived from Medellín Dunite was characterized mineralogically and its influence on the physical properties and unsaturated undrained shear strength was evaluated. The samples were taken in the area adjacent to “Canteras de Colombia”, in Bello municipality (Antioquia, Colombia), on the east side of the Medellín-Bogotá highway. To obtain a relationship between mineralogy and physical-mechanical properties, mineralogical characterization with X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Mössbauer spectroscopy was done to determine the mineral phases present at three depths above 1.80 m in a soil profile derived from Medellín Dunite. The index properties and undrained shear strength of these soils were determined, the latter by the unconfined compressive strength (UCS) test and unconsolidated-undrained (UU) triaxial compression test. The residual soils of Medellín Dunite, have a particular mineralogical composition, which has a significant bearing on their physical-mechanical behavior. The more superficial soils (0.00 a 0.30 m) are richer in iron oxides and hydroxides (hematite, maghemite, and goethite) and aluminum hydroxides (gibbsite), forming bonds between the particles that produce soil aggregation. They are of lateritic behavior and fragile, and present, more significant cohesion and larger undrained shear strength than deeper soils (0.30 m to 1.80 m), these present lower content of oxides and oxi-hydroxides and higher content of silicates like clinochlore and tremolite.

Authors: García-Benítez Silvia Raquel , Arana-Hernández Omar Alejandro
Published: March 2023

A case study testing the effectiveness of neural networks for permeability determination in heterogeneous media using basic rock properties is presented. The dataset used consists of 213 core samples from the Morrow and Viola formations in Kansas, United States. The characterizing parameters of the cores are porosity (ϕ), water and oil saturations (Sw and So), and grain density (GD), and the additional variables from well logs are induction resistivity (ILD), gamma ray (GR) and neutron-porosity (NPHI). The neural predictions are compared with permeability values obtained from three semi-empirical models (Timur, Coates, and Pape) widely used in reservoir characterization. It is concluded that the neural network provides the best overall prediction quantified by the highest correlation coefficients (R and R2) far above those achieved with conventional methods in formations with rock heterogeneity and complex diagenetic nature. Applying Timur’s method R was 0.58 and R2 was 0.343, for Coates’ model R was 0.60 and R2 0.365 and for Pape’s model R was 0.60 and R2 was 0.372, while for the neural model, 0.97 and 0.94 were obtained for R and R2, respectively.

Community-Based Integrated Child Protection Policy during the Covid-19 Pandemic in Palangka Raya
Authors: Sari Mita
Published: March 2023

Child Protection is all activities to ensure and protect the children and their rights to live, grow, develop and participate optimally by human dignity, and protect from violence and discrimination, including the most vulnerable groups of violence. The Covid-19 pandemic provides an excellent opportunity for violent behavior against children. Local governments are obliged to guarantee the implementation of prevention of violence against children and support the national policy on prevention, which is implemented through Community-Based Integrated Child Protection. Community-Based Integrated Child Protection is a government program that empowers the community to play a role in the program, thereby being accepted by the community. This article also examines the factors that cause violence against children during the Covid-19 in Palangka Raya and efforts to prevent it. Parents ‘unpreparedness to adapt to changes in routine during the pandemic, changes in children’s learning schemes, and family economic pressure due to the pandemic further exacerbates parents’ psychology. Meanwhile, parents’ knowledge in childcare is relatively minimal- thus, the child is in a position prone to violence. Prevention efforts can be started by strengthening the role and function of the family, then strengthening the role of schools in providing understanding to parents about the importance of educating children without violence, and strengthening the role of religious institutions and community institutions at the local level to provide education on child protection. In addition, family economic empowerment is also important.

Published: March 2023

This research is based on the low understanding of students’ mathematics. One of the causes for the low understanding of students’ mathematics is a factor in the students themselves in the form of student difficulties in solving problems related to the material in the Differential Calculus course. The purpose of this study was to describe the difficulties of students’ mathematical understanding in solving problems in the Differential Calculus Course using the online learning model. This type of research uses a qualitative approach and is descriptive in nature. The subjects of this study were first semester students taking Differential Calculus courses in the Mathematics Education study program, Muhammadiyah University of Tapanuli Selatan, Academic Year 2020/2021. The instrument used in this study was an interview. The results showed that the difficulties of students’ mathematical understanding in solving problems in the Differential Calculus course using the online learning model were related to technical difficulties, adaptation difficulties and internal difficulties for each individual student. To overcome these difficulties, it is necessary to have a more varied strategy for using online learning media.

In accordance to the development of information technology and the industrial revolution 4.0, interaction between counsellors and clients is not only done through face-to-face relationships, but also through the virtual (internet) of the e-Personal Counselling (e-PC) which discuss problems, anxieties, and anxieties are a part of everyone’s life from time to time. Sometimes problems seem so overwhelming that it is difficult to concentrate on studying and managing daily obligations. Sometimes students avoid seeking for help when they feel unmotivated or have unclear sensations and something is not right. While students conducting counselling conventionally feel insecure and dare to meet counselling guidance teachers, in consequence the students not being able to convey all the problems they have, besides that many students still think that the Counseling Teacher is like the police school where every student who meets the teacher must be problematic students. So, e-Personal Counseling (e-PC) is expected to be a solution to solving students’ problems. The national exam also makes teachers, school administrators and worried if their children do not pass the national exam. These concerns have even triggered the emergence of new problems, such as students who are too stressed before the national exams, suicide, or teachers and school principals who commit acts of cheating in order to graduate their school students.

Developing a Learning Model Based on Hybrid Learning and PjBL
Authors: Sabir Ramadhan Muhammad , . Rumondang
Published: March 2023

Currently, student interest in teaching and learning in schools is declining, coupled with high youth unemployment, the same is also happening in universities. The existing learning model is only teacher-oriented, tends to be passive in order to reduce the nature of learning, students must continually build new ideas based on their learning experiences in order to be able to think creatively and solve problems in the material presented by the teacher. The model of electronic learning (e-learning) in higher education institutions that takes advantage of the advantages of information and communication technologies (ICT), offers a concept of learning where there is a transformation of learning from conventional form to digital form, both in content and in system. has shortcomings, namely not having interaction in the learning process; Project-based learning (PjBL) is one of the innovative learning implemented, but it has not had a sufficient impact on increasing the activity, creativity and productivity of students, especially in the design of a project. This study aims to determine the needs desired by lecturers and students in implementing learning in the multimedia and animation technology course. Results of research that based on the needs analysis performed, students expect the presence of a new learning model that can maximize learning. Based on the needs analysis carried out, the teacher expects a new learning model capable of maximizing learning. Lecturers and students expect a learning model capable of collaborating in the use of information technology and skills required in the 21st century.
