Authors: Timofeeva K. E. 
Published: May 2024

Purpose. The purpose of the article is to substantiate the application of a collective method of teaching in computer science classes in the system of secondary vocational education, contributing to an increase in the level of cognitive activity of students.Research methodology. The idea of the study is related to the implementation of collective learning methods in computer science classes to increase the level of cognitive activity of students. The use of collective learning methods in computer science classes is considered from three positions: organizational, methodological and diagnostic. The organizational aspect includes the conditions for the formation of student groups and scenarios of their interaction in the learning process. The methodological aspect is related to the selection and preparation of special educational and methodological support, including teaching methods. The diagnostic aspect provides an assessment of the effectiveness of learning the educational material, the level of cognitive activity and the state of the psychological atmosphere in the classroom. The measurement of the level of cognitive activity is carried out with the help of a simplified three-dimensional diagnostic method by O. Markelova. The observation of changes in the psychological atmosphere in the classroom is carried out by the method of pedagogical observation.Results. Based on the adaptation of the principles and advantages of collective learning methods (according to V. Dyachenko) to the tasks of the secondary vocational education system, the conditions for the formation of student groups and scenarios of their interaction in the process of teaching computer science were outlined. A training cycle has been proposed for the implementation of a collective method of teaching in computer science classes and a collection of digital educational resources has been compiled. Diagnostic tools have been adapted to identify the level of cognitive activity in computer science classes. The diagnosis of the level of cognitive activity and the effectiveness of learning material in computer science classes was carried out, as well as the psychological atmosphere in computer science classes was analyzed.Conclusions. The use of collective teaching methods in computer science classes in the secondary vocational education system helps to increase the level of cognitive activity of students and, as a result, provides a comfortable psychological atmosphere in the classroom and increases the effectiveness of learning material.
Chitosan-incorporated Bioceramic-based Nanomaterials for Localized Release of
Therapeutics and Bone Regeneration: An Overview of Recent Advances and
Progresses

Abstract:
The usage of nanoparticles in tissue engineering applications has increased significantly
in the last several years. Functional tissues are developed by regulating cell proliferation,
differentiation, and migration on nanostructured scaffolds containing cells. These
scaffolds provide an environment that is more structurally supportive than the microarchitecture
of natural bone. Given its exceptional properties, such as its osteogenic potential,
biocompatibility, and biodegradability, chitosan is a good and promising biomaterial. Unfortunately,
chitosan's low mechanical strength makes it unsuitable for load-bearing applications.
By mixing chitosan with other biomaterials, this drawback might be mitigated.
Bone tissue engineering uses both bioresorbable materials like tricalcium phosphate and
bioactive materials like hydroxyapatite and bioglass. Alumina and titanium are examples of
bioinert materials that are part of these bioceramics. When produced at nanoscale scales, these materials have a
larger surface area and better cell adhesion. This review paper will go into great detail on the bioinert, bioresorbable,
and bioactive nanoceramics-reinforced chitosan scaffolds for bone tissue engineering.
Non-enzymatic Glucose Detection by Fe2O3 Nanorods-reduced Graphene
under Physiological pH
Authors: Yu Jiacai , Shan Xianglu , Zhou Dengfa , Zhao Xueqin , Sheng Weiqin 
Published: May 2024

Background:
Non-enzymatic detection has become a research hotspot because of its alternativity
in solving problems compared to enzymatic biosensors, but most of those sensors require
a strong basic pH environment (higher than 10) to active their surface, restricting their use in
clinical detection because the pH of body fluid is around 7.4. Furthermore, metal oxide sensors
with specific morphologies are reported to have a fast electrocatalytic response. Therefore, Fe2O3
nanocomposites with porous structure are selected for glucose detection research in a physiological
pH environment.

Objective:
The study aimed to assess the potential use of porous reduced graphene oxide-Fe2O3
nanorods in glucose detection in a physiological pH environment.

Method:
Hydrothermal method was used to prepare porous Fe2O3-rGO NRs (Nanorods) and hollow
Fe2O3/C nanoparticles. Cyclic voltammetry and electrochemical impedance spectroscopy
were used to evaluate the performance of our materials.

Results:
Porous-reduced graphene oxide-Fe2O3 nanorods have exhibited better performance than
hollow carbon-Fe2O3 core-shell nanoparticles for glucose detection in a physiological pH environment.

Conclusion:
Non-enzymatic glucose sensing based upon cavity Fe2O3-rGO NRs under a physiological
pH environment has been successfully realized, attributing to their high electron mobility
and large specific surface area. Furthermore, the results of this work indicate that the glucose sensor
prepared here has shown good repeatability and stability, which suggests its potential use in
clinical detection.

Published: May 2024

Aims
This study aims to understand how clinic-based Community Health Workers could address barriers to viral suppression and improve HIV management among Black people living with HIV.

Background
South Florida is home to the greatest number of people living with HIV (PLH) in Florida, and Black communities are disproportionately impacted. Among the most promising strategies to improve HIV outcomes among Black PLH (BPLH) are Community Health Worker (CHW) interventions. Traditionally, CHWs assist PLH in non-clinical environments, and little data exists on the effects of CHW strategies in clinical settings.

Methods
From March 2021 to January 2022, we administered semi-structured interviews to patients, caregivers, and clinic staff to assess their perceptions of barriers to HIV care, facilitators of HIV care, and views on CHWs using a rapid qualitative analysis framework.

Results
There was significant overlap between clients and providers regarding the perceived barriers and facilitators to HIV care. Emergent themes reflected concepts surrounding HIV policy and clinic limitations, stigma across clinic- and community-based settings, and suggestions on ways CHWs can address these concerns.

Conclusion
The results suggest embedding CHWs into HIV clinical teams may be an efficacious approach to address unmet social needs and overcome systemic barriers to HIV care, leading to improved care engagement and HIV outcomes among BPLH.

Authors: Suarez-Lledo Victor , Ortega-Martin Esther , Carretero-Bravo Jesus , Ramos-Fiol Begoña , Alvarez-Galvez Javier 
Published: May 2024

Background
During the COVID-19 pandemic, social media platforms have been a venue for the exchange of messages, including those related to fake news. There are also accounts programmed to disseminate and amplify specific messages, which can affect individual decision-making and present new challenges for public health.

Objective
This study aimed to analyze how social bots use hashtags compared to human users on topics related to misinformation during the outbreak of the COVID-19 pandemic.

Methods
We selected posts on specific topics related to infodemics such as vaccines, hydroxychloroquine, military, conspiracy, laboratory, Bill Gates, 5G, and UV. We built a network based on the co-occurrence of hashtags and classified the posts based on their source. Using network analysis and community detection algorithms, we identified hashtags that tend to appear together in messages. For each topic, we extracted the most relevant subtopic communities, which are groups of interconnected hashtags.

Results
The distribution of bots and nonbots in each of these communities was uneven, with some sets of hashtags being more common among accounts classified as bots or nonbots. Hashtags related to the Trump and QAnon social movements were common among bots, and specific hashtags with anti-Asian sentiments were also identified. In the subcommunities most populated by bots in the case of vaccines, the group of hashtags including #billgates, #pandemic, and #china was among the most common.

Conclusions
The use of certain hashtags varies depending on the source, and some hashtags are used for different purposes. Understanding these patterns may help address the spread of health misinformation on social media networks.

Анализируется частота фундаментальной моды F собственных колебаний Земли 0S2, выделенная в спектрах геомагнитных вариаций в Геофизической обсерватории (ГФО) «Михнево» ИДГ РАН, в период сильных землетрясений. Показано, что величина F принимает разные значения в зависимости от даты события, причем значения F выше в периоды, характеризующиеся уменьшением скорости вращения Земли, и ниже - в периоды ее увеличения. По результатам сопоставительного анализа результатов магнитных измерений и данных каталога открытого доступа IERS получена эмпирическая зависимость между вариациями F и скоростью вращения Земли.
The frequency of the fundamental mode F of the Earth’s natural oscillations 0S2, identified in the spectra of geomagnetic variations at the Mikhnevo observatory of the IDG RAS, during strong earthquakes is analyzed. It is shown that the value of F takes different values depending on the date of the event, and the values of F are higher during periods characterized by a decrease in the Earth’s rotation rate, and lower during periods of its increase. Based on the results of a comparative analysis of the results of magnetic measurements and the data of the IERS open access catalog, an empirical relationship was obtained between the variations in F and the Earth’s rotation rate.
Семантика тональности b-moll в сочинениях Ф. Листа (на примере транскрипции песни Ф. Шуберта «Ее портрет» и Венгерской рапсодии № 3)
Authors: Н.Г. Стейт 
Published: May 2024

В статье рассматривается семантика тональности b-moll в произведениях авторов разных эпох — барокко (И. С. Бах), начала XIX в. (Л. Бетховен), романтизма (Ф. Шуберт и Ф. Лист). Комплексный семантический анализ позволил выявить ряд отличительных особенностей, объединяющих трактовку данной тональности в творчестве указанных композиторов, например, использование ими схожих музыкально-риторических фигур (katabasis, epizeuxis). Прослеживаемая преемственность символической трактовки b-moll, а также и других тональностей (например, E-dur), дает возможность приблизиться к интерпретации смысла основополагающих внутритекстовых знаков рассматриваемых музыкальных произведений, что в свою очередь является «отправной точкой» формирования музыкально-художественного образа. Основное внимание в статье уделено анализу трактовки семантики b-moll в творчестве Ф. Листа. Делается вывод о том, что композитор, во многом поддерживая уже сложившуюся ранее традицию в интерпретации тональности, в то же время вкладывал в нее конкретные, подчас поддающиеся вербализации значения.
The article deals with the semantics of b-moll tonality in the works of composers of different epochs — Baroque (J. S. Bach), early 19 th century (L. Beethoven), Romanticism (F. Schubert and F. Liszt). Complex semantic analysis thereof allowed us to identify a number of distinctive features shared in the treatment of this tonality in works of the above composers, for example, their use of similar musical and rhetorical figures (katabasis, epizeuxis). The traceable continuity of the symbolic interpretation of b-moll and other tonalities (for example, E-dur) makes it possible to approach the interpretation of the meaning of the fundamental intra-textual signs of the musical works in question, which in turn is the “starting point” for formation of a musical and artistic image. The main attention in the article is paid to the analysis of the interpretation of the semantics of b-moll in the works of F. Liszt. The conclusion is made that the composer, in many respects supporting the previously established tradition of its interpretation also implied specific meanings that could yield verbal explication.

Published: May 2024

Jerawat (acne vulgaris) merupakan salah satu penyakit dermatologis paling umum dalam kehidupan sehari-hari utamanya pada masa remaja. Lebih dari 80% orang mengalami permasalahan jerawat pada masa remajanya. Dalam menilai tingkat keparahan jerawat perlu dilakukan penilaian secara obyektif dengan prosedur perawatan medis. Penilaian jerawat secara tradisional umumnya dilakukan oleh dokter kulit dengan menentukan jenis dan jumlah lesi dimana sering kali penilaian ini memakan waktu dan mengganggu efisiensi dalam penilaian jerawat. Kerangka kerja ini menguji praproses gambar dengan menggunakan metode red color detection, threshold, enhanced image dan penggabungan enhanced image dan red color detection dalam klasifikasi gambar jerawat. Selain itu beberapa metode klasifikasi diterapkan untuk menguji data masukan dari penerapan praproses yang dilakukan. Adapun metode klasifikasi yang digunakan adalah NN, SVM, KNN dan VGG16 selain itu penerapan fitur ekstraksi juga diterapkan. Penggunaan fitur ekstraksi menggunakan VGG16 dilanjutkan dengan Principal Component Analysis (PCA) dimana penerapan PCA dilakukan untuk meningkatkan efisiensi komputasional. Dengan data masukan enhanced image yang kemudian diklasifikasikan menggunakan VGG16 memberikan hasil akurasi terbaik mencapai 69% . Kedepannya metode praproses enhanced image dapat diterapkan pada kumpulan data yang berbeda dikarenakan tidak dipungkiri bahwasanya kumpulan data ACNE04 memiliki banyak noise pada citra.

The use of modern methods for assessing the genotypic diversity of breeding material is effective in crop improvement. Interpretation of the results of a study of the fatty acid biochemical composition in seeds of hemp (Cannabis sativa L.) accessions is one of important stages in breeding oilseed varieties, since hemp possesses a unique fatty acid composition (FAC) among other oilseed crops in Russia. Studies of regularities in formation of seed oil FAC and the principal component analysis (PCA) of fatty acid contents have scientific significance and practical value for ensuring the acceleration of oilseed variety breeding aimed at improving quality and biological activity of oil. The use of PCA can be an effective in achieving this goal. The fatty acid profile of oil has been evaluated at the N.I. Vavilov Institute of Plant Genetic Resources in 25 hemp accessions from the VIR hemp collection. Local and industrial hemp varieties and breeding material of the Middle Russian ecotype were grown in Penza Province with a temperate continental climate on meadow-black soils of the Middle Volga Region of Russia. The seed oil FAC was studied using gas-liquid chromatography with mass spectrometry on an Agilent 6850 chromatograph. The results were processed using the UniChrom and AMDIS software. High content of omega-3 stearidonic fatty acid was found in accessions k-205 from Ukraine (1.23%) and k-168 from Russia (0.87%); that of α-linolenic acid in k-168 from Russia (0.82%) and k-224 from GDR (0.39%); of linoleic acid in k-154 (67.29%), k-360 (66.24%), and k-150 (64.58%) (all three from Russia); of γ-linolenic acid in k-88 from Russia (2.43%) and k-211 from GDR (1.92%). It has been established that the formation of hemp seed oil FAC is a multifactorial process. The main factor determined 27.8% of the variability. The presence of both positive and negative factor loadings was revealed. The highest factor loading for the variance of a complex of characters of the oil FAC is on the main factor, i.e. linoleic acid (+0.73). In relation to this acid, negative loadings were detected for myristic acid (−0.81), lauric acid (−0.78), palmitoleic acid (−0.72), and oleic acid (−0.72). The content of bioactive omega-6 diunsaturated linoleic acid was negatively associated with the content of omega-9 monounsaturated oleic acid, as well as with the content of polyunsaturated omega-6 γ-linolenic, omega-3 stearidonic, and omega-3 α-linoleic acids. The obtained information can be used for identifying accessions with the optimal FAC for their involvement in breeding oilseed hemp varieties.

Published: May 2024

Background. Climate change on the planet requires the creation of cultivars adapted to new conditions, which suggests a constant search for sources of the required traits, and the VIR cotton collection provides unlimited opportunities for breeding. Also, the harsh conditions of the northwestern Astrakhan region make it possible to identify the potential capabilities of the accessions. Materials and methods. 25 accessions of the VIR cotton collection were studied at the Caspian Agrarian Federal Scientific Center of the Russian Academy of Sciences (PAFSC RAS) in 2021 against the backdrop of adverse weather conditions. Comparative assessment of morphological and economically important features was carried out according to the VIR methodology. Factor analysis based on the principal component method has been performed. Excel 2016 and STATISTICA 7.0 were used. Results and discussion. The study resulted in the identification of accessions exceeding the ʻAC 5ʼ standard in terms of the yield. The Chinese accessions had a very good fiber yield and can serve as sources of this trait, although they are not too precocious and are characterized by a medium-size capsule. Unfavorable weather conditions during the period of fiber formation did not facilitate obtaining a very good quality fiber, but some accessions yielded fiber with a length of 32-33 mm. Conclusions. Factor analysis showed that American accessions are the least suitable for the conditions of the northern Astrakhan Region due to their late maturity and tall stature. The search for appropriate sources is promising among accessions originating from other regions.
