ОСОБЛИВОСТІ ФОРМУВАННЯ ІНШОМОВНОЇ КОМУНІКАТИВНОЇ КОМПЕТЕНТНОСТІ У ДІТЕЙ СЕРЕДНЬОГО ДОШКІЛЬНОГО ВІКУ
Authors: Коновалова Надія
Published: July 2023

Стаття присвячена особливостям формування іншомовної комунікативної компетентності у дітей середнього дошкільного віку.

Автором проаналізовано еволюцію поглядів на вплив раннього двомовства на розвиток дітей дошкільного віку: з’ясовано причини негативного ставлення до формування іншомовної комунікативної компетентності у дітей середнього дошкільного віку у середині ХХ ст.; обґрунтовано недоцільність твердження щодо мозкового напруження під час оволодіння другою мовою у дошкільному віці задля чого виділено та охарактеризовано основні механізми оволодіння дітьми середнього дошкільного віку другою мовою; з’ясовано сучасне відношення до наслідків формування іншомовної комунікативної компетентності у дітей середнього дошкільного віку та визначено його як здебільшого нейтрального чи позитивного; обґрунтовано недоцільність побоювань у сучасних наукових колах щодо згубного впливу двомовства на швидкість добору слів, оволодіння словниковим запасом, засвоєння рідної мови, самоідентифікацію.

У результаті аналізу експериментальних досліджень у сфері білінгвізму та наукової літератури у зазначеній галузі узагальнено позитивні наслідки формування іншомовної комунікативної компетентності у дітей середнього дошкільного віку по відношенню до когнітивного розвитку (гнучкість мислення, розвиток творчого мислення, креативність, підвищення уваги, її переключення та ін.), розвитку метолінгвістичних здібностей, емпатії, оволодіння третьою і подальшими мовами, раннього оволодіння грамотою, мотивації до оволодіння другою мовою. Підсумовано, що формування іншомовної комунікативної компетентності у дітей середнього дошкільного віку має позитивний вплив не лише на якість мовлення другою мовою, але й виконує інші педагогічні завдання як то розвиток мозкових структур та вищих психічних функцій.

У статті проаналізовано наукові погляди на доцільний час початку та методи формування іншомовної комунікативної компетентності. З’ясовано залежність методів формування іншомовної комунікативної компетентності від віку дитини. Зроблено висновок, що єдиним можливим та ефективним методом формування іншомовної комунікативної компетентності у дітей середнього дошкільного віку є несвідоме оволодіння мовою під впливом мовного середовища із застосуванням природних механізмів оволодіння мовою.

У цій статті досліджується концепція домашнього завдання, його обсяг і потенційне навантаження, яке воно несе для учнів. Зокрема, досліджується необхідність домашніх завдань у навчанні математики, ідеальний обсяг домашніх завдань, найефективніша форма завдань і час, необхідний для їх виконання. Додатково розглядаються сучасні вимоги до організації домашніх завдань з математики під час дистанційного навчання.

У статті досліджено сучасний стан виконання домашніх завдань у математичній освіті з урахуванням проблем, з якими стикаються учні під час виконання завдань великого обсягу. Відображено питання впливу надмірної кількості домашніх завдань на психічне благополуччя учнів та підкреслена необхідність збалансованого підходу, який сприяє ефективному навчанню, не перевантажуючи учнів. Обговорення також стосується важливості чіткої комунікації та вказівок з боку вчителів, щоб забезпечити відповідність домашніх завдань запланованим результатам навчання.

Крім того, у статті наголошено на сучасних вимогах до організації домашніх завдань у позакласній математичній освіті. Розглянуті інноваційні підходи та методології, що можуть підвищити ефективність домашніх завдань, такі як використання технологій, сприяння спільному навчанню та персоналізація завдань на основі індивідуальних потреб та інтересів учнів. У статті також висвітлюється роль формувального оцінювання в рамках домашнього завдання, що дає змогу педагогам надавати своєчасний зворотний зв’язок і підтримувати прогрес учнів.

Досліджуючи еволюцію організації домашніх завдань у математичній освіті, ця стаття сприяє постійному діалогу щодо вдосконалення педагогічної практики та залучення учнів. Отримані результати підкреслюють важливість досягнення балансу між освітніми перевагами домашнього завдання та потенційним тягарем, який воно може накласти на учнів.
Scientific Metrics Analysis of Literature Related to Sustainable Wood Projects
Authors: Novotni A. , Toth Z.
Published: July 2023

An analysis of the literature on wood projects (n = 205) was conducted to understand current scientific trends, key issues, and the appropriate representation of scientific results. Four scientific questions were addressed: whether the number of citations in the literature follows a power function distribution after a value, whether there is any relationship between the number of articles and the number of citations per year, whether the publications available in Scopus can be considered a "true" representation of the publications, and whether the Lotka distribution for author productivity holds for the publication sample on wood projects. The power function distribution test shows that most articles have very few citations, while some articles have very many. This suggests that the scientific value of articles is not necessarily determined by the number of citations. There is a correlation between the number of publications and citations over the same period or slightly skewed in time. The Bradford distribution suggests that publications available in Scopus describing wood projects cannot be considered as a real representation of the publications on the subject. Despite this, the frequency of author productivity follows a Lotka distribution.
Relationship between English Proficiency and Academic Achievement of Indonesian EFL Postgraduate Students
Authors: Devi Anit Pranita
Published: July 2023

There is still a debate about using English proficiency in determining one's academic success or access to an opportunity. Hence, research on the correlation of language proficiency and academic achievement is urgently needed. This study attempted to investigate the relationship between Indonesian postgraduate students’ English language proficiency and their academic achievement. To achieve the objective, 54 male and female postgraduate students majoring in English education at a university in Bandung were involved as the sample. Students’ language proficiency was seen from their Test of English as a Foreign Language (TOEFL) scores and their grade point average (GPA) was used to indicate their academic achievement. All data were analyzed through manual computation of Pearson Product-moment correlation. The result revealed that there is a significant positive linear correlation between English language proficiency and academic achievement.  This result suggests that as the English proficiency increases, so does academic achievement. The results are expected to provide insight in understanding whether English language proficiency can increase academic success, especially in educational settings where English is the primary medium of instruction.

The frontiers of nanomedicine are consistently being challenged by the gradually expanding knowledge of the properties of nanoparticles. Toward this end, biogenic synthesis of silver nanoparticles utilizing natural compounds in plants as reducing and capping agents grabbed considerable attention, in lieu of synthetic hazardous physical and chemical techniques. Green synthesis of silver nanoparticles (AgNPs) has proven safe and effective in treating type 2 diabetes mellitus. Currently, biogenic silver nanoparticles have gained importance as safe and efficient antiglycation agents. Therapeutic strategies by employing nanomedicines from natural sources have been initiated to end the limitations of currently available medications for the treatment of various disorders, including diabetes, Alzheimer’s, cancer, and hepatitis. This article highlights the medicinal efficacy of silver nanoparticles synthesized from different plant extracts for their antidiabetic potential characterized through various in vivo and in vitro assays and unravels their unique properties. This article also focuses on the signaling pathways linked to type II diabetes and the demand for nanomedicine and greener pathways for future pharmacological industries.Keywords: Biogenic silver nanoparticles, antioxidant, Type 2 Diabetes Mellitus (T2DM), α-glucosidase assay, α-amylase assay
Self-Leadership in Sozialen Organisationen. Eine Antwort auf die komplexen Anforderungen der Arbeitswelt
Authors: Löhe Julian , Kunze Jana
Published: July 2023

Sich selbst führen? Geht das überhaupt? Die Kurzantwort: Ja, aber… Führung ist mehr als die Ausübung von Macht und Autorität. In Organisationen der Sozialen Arbeit stehen qua Auftrag und Ziel die zwischenmenschlichen Beziehungen im Zentrum. Deshalb ist dort die Fähigkeit und Möglichkeiten zur Selbstreflektion von Mitarbeitenden und Führungskräften besonders bedeutsam. Dem Self-Leadership liegt der Ansatz zugrunde, dass Menschen sich durch einen reflektierten Umgang mit der eigenen Person individuell führen können. In vorliegender Publikation wird die Frage nach diesem „aber“ beleuchtet: wie kann Selbstführung unter Berücksichtigung einer Individualperspektive, wie auch aus Perspektive der Organisation umgesetzt werden? Im Rahmen des Holistic-Individual-Ansatzes schließt dieses Fachbuch eine Lücke in der Führungslehre für Organisationen der Sozialen Arbeit, indem systematisch der Frage von Selbstführung nachgegangen wird. Nach der Lektüre dieses Fachbuches wissen Sie, wie und wo Sie bei sich selbst und in der Organisation ansetzen müssen, damit Self-Leadership in einer Organisation der Sozialen Arbeit als Konzept implementiert werden kann.
Mutterschaft und Feminismus. Eine Studie zu Konzepten feministischen Mutterseins
Authors: Baig Samira
Published: July 2023

Schließen sich Muttersein und Feminismus aus? Eine Analyse feministischer und gendertheoretischer Zugänge zeigt, dass Mutterschaft durchgängig als Einschränkung von Emanzipationsbegehren thematisiert wird. Die Autorin zeichnet diese Diskurse nach und entwickelte im Rahmen einer qualitativen Studie Konzepte feministischen Mutterseins. Es wird dabei nicht nur das Spannungsfeld Mutterschaft und Feminismus im Alltag feministischer Mütter sichtbar, sondern es konnten auch emanzipatorische Strategien in Bezug auf Mutterschaft identifiziert werden. Diese stellen Gestaltungs- und Handlungsspielräume dar, von denen auch Mütter* profitieren können, die sich nicht als Feminist*innen verstehen.
Direkt-demokratisch oder doch repräsentativ: Welche Entscheidungsmodi präferieren Bürger*innen?
Authors: Vetter Angelika , Brettschneider Frank
Published: July 2023

Demokratische Entscheidungen werden in repräsentativen Demokratien durch die von den Bürger*innen auf Zeit gewählten Repräsentant*innen getroffen. Alternativ gibt es in allen Bundesländern aber auch die Möglichkeit, dass Bürger*innen über Sachfragen auf Länder- oder kommunaler Ebene direkt abstimmen (Bürger- oder Volksentscheide). Wir untersuchen mit Hilfe eines neuen Mess-Ansatzes auf Basis einer repräsentativen Umfrage, welche demokratischen Entscheidungsmodi von den Bürger*innen auf verschiedenen Ebenen des politischen Systems präferiert werden. Berücksichtigt wird erstmalig, dass sowohl repräsentativ-demokratische als auch direkt-demokratische Entscheidungsmodi durch deliberative bzw. dialogische Beteiligungsformate ergänzt werden können. Dabei zeigt sich, dass repräsentativ-demokratische Entscheidungen weiterhin eine starke Unterstützung in der Bevölkerung erfahren, besonders auf der Bundesebene. Allerdings ist der Wunsch nach mehr Dialog und Kommunikation im Vorfeld der Entscheidungen – egal ob repräsentativ- oder direkt-demokratisch – stark und sollte bei Überlegungen zu zukünftigen Reformen demokratischen Entscheidens in der Bundesrepublik Deutschland mehr Aufmerksamkeit finden.
Direkte Demokratie in der Schweiz und die Wirkung auf die Staatstätigkeit
Authors: Wagschal Uwe
Published: July 2023

Der Beitrag untersucht Policy-Wirkungen der direkten Demokratie. Dabei werden sämtliche bisherige Volksabstimmungen, das heißt obligatorische und fakultative Referenden sowie Volksinitiativen, in der Schweiz analysiert. Die Frage, ob Direktdemokratie expansiv oder restriktiv auf die Staatstätigkeit wirkt, ist dabei die erste Forschungsfrage. Dabei stehen die Sozialpolitik und die Öffentlichen Finanzen im Mittelpunkt der Analyse. Zudem wird dann nach den Effekten für die einzelnen Instrumente differenziert. Darüber hinaus werden die Abstimmungsparolen des Bundesrates, des Parlaments sowie der Parteien und Verbände untersucht. Im Ergebnis zeigt der Beitrag einen bremsenden Effekt über alle Schweizer Abstimmungen hinweg. Diese Wirkungen sind nach den einzelnen Instrumenten unterschiedlich, insbesondere das fakultative Referendum entfaltet eine Bremswirkung. Die geringe Zahl expansiver Volksinitiativen verweist darauf, dass der „Gaspedal“-Effekt der Volksinitiative eher gering und indirekter Natur ist. Eine besonders hohe Erfolgsquote mit ihren Abstimmungsparolen weisen die Parteien der politischen Mitte auf. Die Parteien an den politischen Rändern sind dagegen eher deutlich geringer erfolgreich.
Nutzung von elektronischen Marktplätzen in der öffentlichen Beschaffung in Deutschland: Anforderungen, Funktionalitäten und Regelungssystem
Authors: Glas Andreas , Hammer Maximilian , Eßig Michael
Published: July 2023

Elektronische Marktplätze (e-MP) besitzen eine Reihe von Funktionalitäten, die zu mehr Transparenz, Wettbewerb und Wirtschaftlichkeit führen. Das öffentliche Beschaffungswesen in Deutschland hat die Implementierung und Nutzung öffentlicher elektronischer Marktplätze (Ö-e-MP) jedoch noch nicht berücksichtigt, obwohl der öffentliche Sektor grundsätzlich auf größtmöglichen Wettbewerb ausgerichtet ist. Basierend auf der Theorie des unvollkommenen Wettbewerbs erklärt diese Studie die Faktoren, die zu Ineffizienzen im Beschaffungswesen führen. Untersucht wird, inwieweit ein Ö-e-MP einen positiven Effekt auf die öffentliche Beschaffungspraxis in Deutschland haben könnte. Zu diesem Zweck wurde eine Umfrage bei öffentlichen Auftraggebern durchgeführt. Die Ergebnisse zeigen, dass die Nutzung eines Ö-e-MP die Transparenz, den Wettbewerb und die Marktvollständigkeit im öffentlichen Beschaffungswesen insgesamt deutlich verbessern könnte. Darüber hinaus zeigen sich auch weitere positive Auswirkungen auf die Effizienz der öffentlichen Beschaffung. Die Originalität dieser Untersuchung besteht in der Identifikation des digitalen Wettbewerbs als Motor für die Leistungsfähigkeit des öffentlichen Auftragswesens.
50 Jahre Forschungsprojekt ‚Politisch-Administrative Elite‘ / 50 Years of the ’politico-administrative elite’ research project
Authors: Beneke Jasmin Theres , Döhler Marian , Ebinger Falk , Veit Sylvia
Published: July 2023

Berichtet wird über einen Survey, der das Verhältnis von politischen und administrativen Eliten in westlichen Demokratien analysiert. Das in den frühen 1970er Jahren von US-amerikanischen Politikwissenschaftlern initiierte Forschungsprojekt wird seit 1987 für den deutschen Fall fortgeführt. Der hohe Rücklauf des Online-Surveys erlaubt belastbare Aussagen über leitende Beschäftigte in der Ministerialverwaltung und nachgeordneten Behörden sowie den Wandel ihrer Einstellungen und Wahrnehmungen. Gefragt wird u. a. nach der Ausbildung, der Tätigkeit, den politischen Einstellungen sowie den Interaktionen mit anderen Akteuren innerhalb und außerhalb des Regierungssystems. Auch wenn die Nähe zum politischen Prozess zunimmt, lässt sich immer noch ein klar abgrenzbares, verwaltungsbezogenes Rollenverständnis der administrativen Eliten feststellen. In den beiden letzten Erhebungen wurde erstmalig nach dem Umgang mit wissenschaftlicher Expertise sowie den Einstellungen zur Digitalisierung und Social Media-Nutzung gefragt. Es ist geplant, den Survey vor der nächsten Bundestagswahl fortzusetzen.

A machine learning pipeline for extracting decision-support features from traffic scenes1
Authors: Fraga Vitor A. , Schreiber Lincoln V. , da Silva Marco Antonio C. , Kunst Rafael , Barbosa Jorge L.V. , Ramos Gabriel de O.
Published: July 2023

Traffic systems play a key role in modern society. However, these systems are increasingly suffering from problems, such as congestions. A well-known way to efficiently reduce this kind of problem is to perform traffic light control intelligently through reinforcement learning (RL) algorithms. In this context, extracting relevant features from the traffic environment to support decision-making becomes a central concern. Examples of such features include vehicle counting on each queue, identification of vehicles’ origins and destinations, among others. Recently, the advent of deep learning has paved to way to efficient methods for extracting some of the aforementioned features. However, the problem of identifying vehicles and their origins and destinations within an intersection has not been fully addressed in the literature, even though such information has shown to play a role in RL-based traffic signal control. Building against this background, in this work we propose a deep learning pipeline for extracting relevant features from intersections based on traffic scenes. Our pipeline comprises three main steps: (i) a YOLO-based object detector fine-tuned using the UAVDT dataset, (ii) a tracking algorithm to keep track of vehicles along their trajectories, and (iii) an origin-destination identification algorithm. Using this pipeline, it is possible to identify vehicles as well as their origins and destinations within a given intersection. In order to assess our pipeline, we evaluated each of its modules separately as well as the pipeline as a whole. The object detector model obtained 98.2% recall and 79.5% precision, on average. The tracking algorithm obtained a MOTA of 72.6% and a MOTP of 74.4%. Finally, the complete pipeline obtained an average error rate of 3.065% in terms of origin and destination counts.

BACKGROUND: FOXP3 Tregs have been found in breast cancer patients, both humoral and tumor. Survival or prognosis of breast cancer patients seems to correlate with the increase and decrease in FOXP3 Treg. OBJECTIVES: This review aims to provide insights regarding the FOXP3 Tregs involved and their mechanisms in breast cancer prognosis. METHODS: The literature study method is used from primary and secondary libraries. The library search used online-based search instruments such as NCBI-PubMed, Google Scholar, and Elsevier. The data obtained were then arranged according to the framework, data on the relationship between FOXP3 Regulatory T Cells and breast cancer, and writing a journal review was carried out according to the given format. Regulators (Tregs) can inhibit anti-tumor immunity and promote tumor growth. Tregs also play a role in inhibiting cytotoxic T lymphocyte cells by inhibiting the release of granules from CD8+, where CD8+ is important in killing tumor cells. FOXP3 is a Treg-specific biomarker and plays an important role in the development and function of Tregs. RESULTS: Studies on the presence of FOXP3+ Tregs in tumors have shown controversial results. Studies in some tumors reported the presence of FOXP3+, indicating a poor prognosis, whereas studies in other tumors found that FOXP3+ correlated with a good prognosis. CONCLUSION: Regulatory T lymphocytes and TILs in invasive breast carcinoma are still not established. Therefore, further research on the Effect of FOXP3 expression of regulatory T lymphocytes on breast cancer is still important.
Cerebrovascular miRNAs Track Early Development of Alzheimer’s Disease and Target Molecular Markers of Angiogenesis and Blood Flow Regulation
Authors: Chum Phoebe P. , Bishara Mary A. , Solis Summer R. , Behringer Erik J.
Published: July 2023

Background: Alzheimer’s disease (AD) is associated with impaired cerebral circulation which underscores diminished delivery of blood oxygen and nutrients to and throughout the brain. In the 3xTg-AD mouse model, we have recently found that > 10 cerebrovascular miRNAs pertaining to vascular permeability, angiogenesis, and inflammation (e.g., let-7d, miR-99a, miR-132, miR-133a, miR-151-5p, and miR-181a) track early development of AD. Further, endothelial-specific miRNAs (miR-126-3p, miR-23a/b, miR-27a) alter with onset of overall AD pathology relative to stability of smooth muscle/pericyte-specific miRNAs (miR-143, miR-145). Objective: We tested the hypothesis that cerebrovascular miRNAs indicating AD pathology share mRNA targets that regulate key endothelial cell functions such as angiogenesis, vascular permeability, and blood flow regulation. Methods: As detected by NanoString nCounter miRNA Expression panel for 3xTg-AD mice, 61 cerebrovascular miRNAs and respective mRNA targets were examined using Ingenuity Pathway Analysis for canonical Cardiovascular (Cardio) and Nervous System (Neuro) Signaling. Results: The number of targets regulated per miRNA were 21±2 and 33±3 for the Cardio and Neuro pathways respectively, whereby 14±2 targets overlap among pathways. Endothelial miRNAs primarily target members of the PDE, PDGF, SMAD, and VEGF families. Individual candidates regulated by≥4 miRNAs that best mark AD pathology presence in 3xTg-AD mice include CFL2, GRIN2B, PDGFB, SLC6A1, SMAD3, SYT3, and TNFRSF11B. Conclusion: miRNAs selective for regulation of endothelial function and respective downstream mRNA targets support a molecular basis for dysregulated cerebral blood flow regulation coupled with enhanced cell growth, proliferation, and inflammation.

Published: July 2023

Alzheimer’s disease (AD) is a complex, heterogeneous, and progressive neurodegenerative dementia. Although the majority of AD research has primarily focused on disease-associated alterations of the cortex and hippocampus in the cerebrum, emerging evidence has highlighted the cerebellum’s involvement in sleep, cognition, and AD. In this commentary, we discuss a recently published article in Alzheimer’ s and Dementia, which examines changes in cerebellar electrophysiology, sleep-wake cycles, and neuropathology in APPswe/PS1 ΔE9 mice. We also explore the potential role of the cerebellum in AD, offering a fresh perspective on the study of cerebellar involvement in the disease.

BACKGROUND: Accurate prediction of recovery is essential to determine whether a knee-ankle-foot orthosis (KAFO) is required in the subacute phase of stroke. However, there are currently no reliable methods to predict such recovery. OBJECTIVE: This study aimed to determine whether muscle strength of the affected lower limb (affected side LL strength) in stroke patients in the subacute phase who cannot walk without a KAFO can be used to predict the continuous need for a KAFO, using a hand-held dynamometer. METHODS: We enrolled patients with severe hemiplegia (n = 51) who were unable to walk without a KAFO for 10 days after stroke onset. They were divided into two groups depending on the continuous need for a KAFO at 1 month after onset; the KAFO and non-KAFO groups. Logistic regression analysis was used to investigate whether the affected side LL strength was a predictor of the continuous need for a KAFO at 1 month after onset. In addition, significant predictors were analyzed using receiver operating characteristic (ROC) curves. RESULTS: The KAFO and non-KAFO groups included 23 (45.10%) and 28 (54.90%) patients, respectively. The affected side LL strength and pusher syndrome severity were identified as predictors of the continuous need for a KAFO. The predictor with the highest predictive ability was the affected side LL strength, with an area under the ROC curve of 0.80 (95% CI, 0.68–0.93). CONCLUSIONS: Affected side LL strength may be a highly accurate predictor of the need for a KAFO in the subacute phase of stroke.

Published: July 2023

BACKGROUND:

Running-related injuries (RRI) are common among recreational runners, but research exploring lived experiences of a RRI is limited.

OBJECTIVE:

This study aimed to explore the psychosocial aspects experienced by recreational runners hindered in usual running because of RRI.

METHODS:

Individual semi-structured interviews based on a qualitative phenomenological methodology explored injured recreational runners experiences, reactions, thoughts, and feelings. Systematic text condensation was used as the analysis method.

RESULTS:

Three main codes were identified: Reasons for running: ‘ Calm for me is a feeling of my body just relaxing. It may sound a bit weird because you run, but it is kind of a feeling of just being able to unplug‘, Daily life during an injury - besides running: ‘ When I couldn’t run at all, it was super annoying. Several months it was completely empty. It was like there was a hole. There seemed to be missing something because I usually ran‘, Running while injured: ‘ Do I feel pain? Or is it something else? And should I navigate regarding the length of the route and where I run, how fast I run, and with whom I run? ‘.

CONCLUSION:

The recreational runners experiences explored in this study support the importance of bio-psycho-social awareness when physiotherapists meet runners hindered in usual running because of RRI.
Application and testing of RFID Software-Based Shielding in real fashion retail stores
Authors: Mezzogori Davide , Rizzi Antonio , Romagnoli Giovanni , Rosa Mirco
Published: July 2023

PURPOSE:

The present paper investigates the real performances of Software-Based Shielding (SBS) in two different stores of fashion retailers located in Northern Italy.

DESIGN/METHODOLOGY/APPROACH:

The study is based on a double case study analysis. Six different factors have been chosen, with two levels each. Namely, we investigated two different (i) stores; (ii) reader models; (iii) power levels; (iv) classification methods; (v) training data sets and (vi) settings of reference tags. The results have been evaluated in terms of overall and specific accuracies, and in percentage of false front (i.e., tags wrongly located in the sales floor area).

FINDINGS:

SBS proves to be a sound method for classifying tags’ location during normal operations in real-life stores, with overall accuracy up to 0.95. Of the two readers, reader A shows better results in terms of both overall and front accuracy, whereas reader B performs better in terms of rear accuracy and percentage of false front. With respect to the classification method, the combination of Method 2 with reads from reader A provides the best results. With respect to the training data, the use of front and back reads for training performs mostly better than the training with sole front data.

ORIGINALITY:

We are not aware of any other study that performed and reported results of SBS testing under normal operations in real stores. To the best of our knowledge, this study is the first one to report such results.

RESEARCH LIMITATIONS:

Main limitations of our research are the limited set of factors and levels, and the specific classification methods that we used, labelled as Method 1 and Method 2. Also, we did not consider tags disposition and density in our study.

PRACTICAL IMPLICATIONS:

We prove that SBS is a feasible option that could replace physical shielding in retail stores. We call to action for further research on this topic, and for retailers to test it in different store locations.
A computational approach for analysis of intratumoral heterogeneity and standardized uptake value in PET/CT images
Authors: Alshamrani Khalaf , Alshamrani Hassan A.
Published: July 2023

BACKGROUND:

By providing both functional and anatomical information from a single scan, digital imaging technologies like PET/CT and PET/MRI hybrids are gaining popularity in medical imaging industry. In clinical practice, the median value (SUVmed) receives less attention owing to disagreements surrounding what defines a lesion, but the SUVmax value, which is a semi-quantitative statistic used to analyse PET and PET/CT images, is commonly used to evaluate lesions.

OBJECTIVE:

This study aims to build an image processing technique with the purpose of automatically detecting and isolating lesions in PET/CT images, as well as measuring and assessing the SUVmed.

METHODS:

The pictures are separated into their respective lesions using mathematical morphology and the crescent region, which are both part of the image processing method. In this research, a total of 18 different pictures of lesions were evaluated.

RESULTS:

The findings of the study reveal that the threshold is satisfied by both the SUVmax and the SUVmed for most of the lesion types. However, in six instances, the SUVmax and SUVmed values are found to be in different courts.

CONCLUSION:

The new information revealed by this study needs to be further investigated to determine if it has any practical value in diagnosing and monitoring lesions. However, results of this study suggest that SUVmed should receive more attention in the evaluation of lesions in PET and CT images.

This article discusses methods for determining the genetic polymorphism of malaria mosquitoes of the Anopheles maculipennis complex. AN identification of similar species of the maculipennis complex was carried out by the PCR-RFLP method using the second internal transcribed spacer of the ITS2 ribosomal gene cluster. Based on the analysis of the ITS2 rDNA sequence, new Palearctic species were discovered in this collection: An. persiensis (Sedaghatetal., 2003), An. daciae (Nicolescu et al., 2004) and An. artemievi (Gordeev et al., 2004). Previously, a cytogenetic method was used on the territory of Kazakhstan, which included chromosomal polymorphism. It is found in the south of the range of this species (Stegny, 1991; Gordeev and Sibataev, 1996). In populations of malarial mosquitoes of An. messeae of Kazakhstan, new chromosomal inversions have been identified that are not characteristic of this region (Abylkasymova et al., 2019). There is also provided some information about the bioecology and harmful nature of Anopheles messeae mosquitoes. Bloodsucking mosquitoes of the Anopheles maculipennis complex are of great scientific and practical interest since they are known as active bloodsuckers and carriers of pathogens of a number of dangerous human and animal diseases. Based on their own research and literature data, were collected materials on the biology and ecology of Anopheles messeae mosquitoes of the Irtysh River basin. Data on the prevalence and landscape location of mosquitoes in the Maculipennis complex, there are presented seasonal dynamics and daily rhythm of abundance, and harmful value.

he method of morphometric analysis was used to study ultrastructural changes in the mitochondria of the lungs of rats after a single intratracheal injection of chrysotile-asbestos dust into animals at doses of 25 mg and 50 mg. According to morphometric parameters, more serious changes were detected in mitochondria under the influence of asbestos at a dose of 50 mg, which were characterized by a significant increase in the area, perimeter and average diameter of the outer and inner membranes. The value of the area of the outer membrane of mitochondria in intact animals was 0.38±0.02 µm2, the perimeter was 2.52±0.11 µm, the average diameter was 0.75±0.03 µm, for experimental rats (asbestos 50 mg) the data the indicators turned out to be significantly increased and amounted to 0.59±0.04 µm2 (the area of the outer membrane), the perimeter was 3.67±0.19 µm, and the average diameter was 1.06±0.05 µm. For the inner membrane, these indicators in the control were as follows: the area of the inner membrane was 0.33±0.02 µm2, the perimeter was 2.40±0.12 µm, the average diameter was 0.71±0.032 µm, and for asbestos at a dose of 50 mg: 0.56±0.05 µm2 (internal membrane area), perimeter 3.68±0.21 µm, mean diameter 1.06±0.06 µm. Under the action of asbestos in lung cells, a significant decrease in the length of mitochondrial cristae was revealed: 9.11 ± 0.41 μm (control, intact animals), asbestos at a dose of 25 mg: 4.07 ± 0.33 μm and asbestos at a dose of 50 mg: 2.34±0.20 µm. Swelling and destruction of the cristae is observed, and this can be traced by morphometric parameters of the cristae diameter, which accordingly increased under the influence of 50 mg of asbestos by 90.9% (p<0.001). The obtained values of the area of the inner and outer membranes, the diameter and length of mitochondrial cristae made it possible to assess the degree of ultrastructural disorders of mitochondria, which may indicate mitochondrial dysfunction under the action of asbestos.
