Mycobacterium tuberculosis is the causative agent of human tuberculosis; enabling multilayered mechanisms to evade from immune response along with reactivation of the process with subsequent pathogen dissemination. Modification of immune responses through imbalanced intracellular signaling pathways and reprogramming of differential gene expression is one of such mechanisms. Modification targets for M. tuberculosis are the genes which products are involved in lipid metabolism and apoptosis, a key to eliminate intracellular pathogens. here, we review the current scientific data related to this problem: the results of studies published in domestic and foreign literature from the years 2003 to 2022 were systematized and summarized; data on the role of a number of molecular mechanisms regulating lipid metabolism, autophagy and apoptosis in human TB-infection; discuss contemporary ideas about the importance of the VDR signaling cascade controlled by the vitamin D-axis counteracting M. tuberculosis infection, its course and outcome. In addition, there are provided the data on the main M. tuberculosis genetic lines common in Russia and Siberia and the elements of the pathogen-related genetic structure that are important in the context of the topic. The effects of interplay and interactions of intracellular molecular cascades (VDR, NF-kB, MAPK, NFAT5, AMPK, GR) are considered and analyzed, as well as their role in the differential expression of genes that ensure M. tuberculosis inactivation and elimination. Presenting the data confirming that one of the main strategies of mycobacterium immune evasion counteraction to autophagy and apoptosis is implemented through altered VDR signaling pathway, including the epigenetic mechanisms occurring in the pathogen. Based on results of the analysis and summarized literature data (60 articles retrieved from eLIBRARY, PubMed), it is demonstrated that during the thousand-year history of co-evolution with human, M. tuberculosis acquired unique features of genetic organization and mastered the pathways of immune evasion using non-genomic and genomic mechanisms. Available publications confirm that one of the main strategies for M. tuberculosis survival in macrophages is to modify a balance between intracellular signaling cascades controlling the differential expression of genes that provide a proper immune response to infection, followed by pathogen elimination.

Published: March 2023

La naturaleza de la publicidad digital permite que existan constantes cambios en los formatos y técnicas publicitarias que se utilizan en Internet. Al mismo tiempo, los consumidores se han acostumbrado a evadir aquella publicidad notoria y con fines promocionales.

De esta manera, el marketing de contenidos encuentra en el branded content un aliado para hacer publicidad no intrusiva y sobre todo que se adapte a los cambios tecnológicos. Es por ello, que a través del contenido informativo el marketing en tiempo real generó el newsjacking.

El newsjacking es la capacidad de capturar las noticias y adecuarla a los propósitos de la marca. Sin embargo, su cualidad de noticia hizo posible el efecto viral.

El presente artículo describe como el concepto newsjacking evoluciona hasta convertirse en viraljacking, donde las marcas utilizan los acontecimientos relacionados a producciones audiovisuales, temas musicales y hechos que son abordados por el periodismo de espectáculo. En consecuencia, el tratamiento de estos temas resulta convertirse en tópicos de tendencia en las redes sociales.

El trabajo tiene como objetivo el análisis cualitativo del viraljacking, a través de la Teoría de las Apelaciones Publicitarias y Necesidades, las características del formato publicitario y el uso de figuras retóricas visuales. Con este propósito se utilizó el caso de la serie ‘El juego del calamar’, ya que, gracias a su popularidad entre el público usuario de redes sociales se pudo conocer de forma abierta las percepciones en torno a la mencionada técnica.

Published: March 2023

Shoulder subacromial impingement syndrome (SIS) is a mechanical disturbance caused by a multifactorial aetiology, and conservative treatment is the first choice. This study aims to investigate the combined short-term effect of manual therapy and eccentric exercise conditioning on clinical outcomes in the acute phase. We recruited 126 subjects with a SIS of 3 months' duration and divided them into two groups of 63 people each. The experimental group received manual therapy and eccentric exercise; the control group received concentric exercise, spread over 3 weeks, followed by a home program for another 9 weeks. Pain intensity, shoulder elevation range, abductor and external rotator muscle strength, and regional function were obtained at baseline, after 10 sessions of treatment and follow-up at 12 weeks. After the first session and by the end of 3 weeks, a global rating of change (GRC) questionnaire was administered to determine self-perceived improvement. An analysis of variance with repeated measures was applied, and the results showed that there were statistically significant differences in both groups; all outcomes improved after treatment and during follow-up (P < 0.005). However, on intergroup analysis, significant improvement was observed with pain intensity (P < 0.0005), elevation range of motion (P < 0.05) and external rotator muscle strength (P < 0.016) after treatment, and external rotator muscle strength and SPADI score (P < 0.0005) at follow-up by 12 weeks in the experimental group. The between-group comparison revealed that pain reduction by 3 weeks, external rotator muscle strength by 3 and 12 weeks, had resulted in a large effect size. Manual therapy and eccentric exercise can reduce pain intensity, improve shoulder elevation range, and gleno-humeral muscle strength after 12 weeks of training better than concentric exercises. The improvement in shoulder function with the experimental group exceeded the MCID of 13 points, resulting in a large and significant effect size (d = 1.08). The self-perceived improvement (GRC) was significant in the experimental group (P < 0.001) with a clinically significant change greater than the MCID (3 points).
HEAT TRANSFER ENHANCEMENT IN A CHANNEL WITH INCLINED BAFFLES UNDER PULSATING FLOW: A CFD STUDY
Authors: Akcay Selma , Akdag Unal
Published: March 2023

This study numerically investigated hydraulic and thermal performance in a channel with inclined baffles under pulsating flow conditions. The baffles were placed in a staggered arrangement. The governing equations were discretized with the finite volume method (FVM), and the pressure-velocity coupling was handled by the SIMPLE algorithm. The Strouhal number (St: 0.5,1, 2, 3, and 4), pulsation amplitude (A: 0.2, 0.5, and 0.8), and Reynolds number (200 ≤ Re ≤ 1000) were changed. The top and bottom surfaces of the channel were kept at Tω = 350 K, and thermal improvement and friction factor were calculated for a pulsating cycle. The results were given in terms of thermal enhancement (η), relative friction factor (frel), and performance evaluation criteria (PEC). The flow and temperature contours were presented to determine the impacts of the pulsation frequency, the pulsation amplitude, and the Reynolds number. The results showed that the pulsation amplitude and the pulsation frequency contributed remarkably to thermal enhancement with increasing Reynolds numbers, while the heat transfer improved significantly depending on pulsation parameters together with a slight rise in friction factor. The highest thermal enhancement achieved was about 1.47 at Re = 1000, A = 0.8, and St = 4. The highest PEC obtained was approximately 1.12 at Re = 1000, A = 0.2, and St = 4.
Factors Affecting Foreign Direct Divestment by MNEs: An Empirical Analysis of Korean Subsidiaries in Poland
Authors:   The Korea International Trade Research Institute, Ra Wonchan , Jeziorska Marta
Published: March 2023

Purpose – Foreign direct investment (FDI) by multinational enterprises (MNEs) has increased in recent years, and simultaneous foreign direct divestment (FDD) by subsidiaries is also very common. FDD can have a significant effect both on the performance of the MNE and the host economy. This study attempts to theoretically and empirically investigate factors affecting the divestment of Korean MNEs, focusing on subsidiaries in Poland. Design/Methodology/Approach – The study identifies six factors, such as entry mode, experiential local knowledge, business group affiliation, EU-Korea Free Trade Area (FTA), and the type of industry and product through a literature review, and establishes hypotheses regarding the effect of these variables on the subsidiary divestment tendency. The study statistically tested these hypotheses using a Cox proportional-hazards model with secondary data on Korean subsidiaries operating in Poland between 2009 and 2016. Findings – Test results show that Korean MNE subsidiaries in Poland characterized by an entry mode of sole investment, richer experiential local knowledge, affiliation with a business group in Korea, and entry after the EU-Korea FTA were less likely to divest from the Polish market. Research Implications – Although the issue of FDD has become significant from the perspective of both the MNE and local governments, there has not been active academic research. This study is one of the first empirical studies on the divestment of Korean MNE subsidiaries in the European market, and can contribute to academic literature and governmental policymaking.
Main Content and the Evaluation of the Trade-Related Laws of North Korea, as a CISG Contracting State
Authors:   The Korea International Trade Research Institute, Choi Sae-Jin , Shim Chong-Seok
Published: March 2023

Purpose – The purpose of this study is the analysis of legal standards for North Korean Trade-Related Law in order to provide academic implications to enhance the appropriate utilization. Design/Methodology/Approach – This paper uses literature research on North Korean Laws. Findings – The legal standards for the responsibility of contracting parties under North Korean laws were noted. Research Implications – This study focused on the legal basis of North Korean trade law. A summary of the characteristics of North Korean trade law is as follows. First, the composition of individual laws is very monotonous. Since most of the bylaws or subordinate statutes are not kept, there are considerable problems in interpreting or distinguishing the meaning of the law. Second, there are many statutes that omit definitions of terms in individual laws. This is causing confusion due to the absence of legal terminology. Third, there are many laws that are mutually related, so confusion is expected in the application of the law due to the interaction of these laws. Fourth, criminal responsibility is emphasized in the case of the violation of individual laws, and the entity of the state agency controlling trade is not clear in trade-related laws.
Wayfinding Satisfaction on Tourist Revisit Intention: A Moderated Moderation Model of Travel Group Size and Tourism Information Service
Authors:   The Korea International Trade Research Institute, Kim Ko-Woon
Published: March 2023

Purpose – Although researchers have long recognized customer revisit intention as an important post-purchase outcome, less attention has been given to revisit intention in the tourism context. Additionally, the effect of wayfinding satisfaction on tourist revisit intention has been largely overlooked. However, wayfinding in a highly urbanized country, such as South Korea, can be challenging, especially for tourists, which can affect revisit intention. Therefore, the main objective of this study is to investigate the differential effect of wayfinding satisfaction on revisit intention, depending on travel group size, while examining the potential moderating role of tourism information service satisfaction. Design/Methodology/Approach – This study conducts a moderated-moderation analysis of wayfinding satisfaction, travel group size, and tourism information service satisfaction on revisit intention, using the 2019 International Visitor Survey conducted by the Korea Tourism Organization. Findings – The findings reveal that wayfinding satisfaction is positively associated with revisit intention, and this association becomes stronger for tourists that travel in larger groups. The findings further show that the moderating effect of travel group size on the association between wayfinding satisfaction and revisit intention depends on tourism information service satisfaction. Specifically, tourism information service satisfaction exerts a negative moderating impact on the moderating influence of travel group size on the wayfinding satisfaction-revisit intention relationship. Research Implications – As the global coronavirus pandemic enters a recovery phase, growing attention has been directed to tourists, particularly those visiting the same destination multiple times. In this context, this study provides comprehensive insight into how tourist revisit intention is enhanced.
The Future Earnings Predictability of Fundamental Variable and Discretionary Accruals
Authors:   The Korea International Trade Research Institute, Shin Hee-Jeong
Published: March 2023

Purpose – This study investigates whether the future earnings predictability of the fundamental variables (AFS) is different from that of discretionary accruals. Given that AFS is the aggregate score index based on financially fundamental variables which predict the change in future earnings, AFS information is expected to be distinct from discretionary accruals which convey information on earnings persistence, but contain accruals estimation errors. Design/Methodology/Approach – This study uses AFS estimated using Penman and Zhang (2006) variables as the fundamental variable and discretionary accruals measurements according to Dechow et al. (1995) and Kothari et al. (2005). Frequency analysis and portfolio tests on firms listed in Korean stock exchanges (KSE) are conducted. Also, the hypothesis is verified by regression analysis with robust statistic test. Findings – The findings are as follows. First, AFS systematically mitigates the negative effect of discretionary accruals on future earnings increases. Additionally, AFS-based 12 month buy-hold returns are effective, but the discretionary accruals-based returns are not, in part. These results hold consistently on both the portfolio test and regression analyses. Research Implications – The results imply AFS contains information on future earnings increases independent of discretionary accruals. This study contributes to academic research by suggesting the future earnings predictability of accounting information based on financial statement analysis. Also, this study has practical implications in that two measures reflect the partially indifferent information of each other, and suggest an investment strategy exploiting ex-ante information.
Understanding Consumer Perceptions of Brand Globalness and Localness: The Roles of Self-Regulatory Focus
Authors:   The Korea International Trade Research Institute, Xi Liu , Han Bang-Wool
Published: March 2023

Purpose – The purpose of this paper is to investigate how self-regulatory focus influences the relationship between consumer perception of a brand nature and purchase intentions. This study uses perceived brand globalness (PBG) and perceived brand localness (PBL) to measure consumer perceptions of brand natures and examines the moderating effects of promotion-oriented vs. prevention- oriented regulatory focus on consumers’ intent to purchase global or local brands. Design/Methodology/Approach – This study conducted an online survey with Chinese consumers and data were collected using social media applications. To analyze the data, PROCESS modeling in SPSS 23.0. was hired in this study. Findings – The findings show that there is a significant moderating effect of promotion-focused self-regulation on the relationship between PBL and purchase intention. On the other hand, consumers with prevention-focused self-regulation show stronger purchase intention toward brands perceived as global (PBG). This study adds further evidence for the effectiveness of PBL and PBG by demonstrating their role among consumers with different self-regulatory focuses. Research Implications – The study contributes to the body of literature on PBG/PBL by examining the associations between self-regulatory focus and consumer purchase intentions. Furthermore, the findings may help brands to make more appropriate positioning decisions depending on the assessment of target consumers' self-regulatory focus. Thus, the findings of this study provide international brand managers with meaningful implications in developing marketing strategies.
Prediction of the concentration inhomogeneity of powder magnetic hard alloys based on the Fe-Cr-Co-Mo system and the effect of Sm additions on their magnetic properties
Authors: Marieva M. A. , Shatsov A. A.
Published: March 2023

Hysteresis alloys based on Fe-Cr-Co system are extensively used in the instrument-making industry as a material for synchronous motors of navigation systems, in the electronic industry, and other mechanical engineering fields. The following requirements are imposed on Fe-Cr-Co alloys: temperature stability of magnetic characteristics over time, manufacturability, low porosity and concentration inhomogeneity, which allow to obtain high-quality magnetic and mechanical properties. Materials based on conventional alloying systems, such as Fe-Cr-Co, have outlived themselves. An urgent line of the development of new materials and improvement of the properties of existing ones is alloying with rare-earth metals. The effect produced by Sm addition on powder analogs of Fe-Cr-Co system remains unstudied. In this paper, 22Kh15K4MS powder magnetic hard alloy alloyed with samarium in an amount of 0.5 wt. % was studied. The billets were obtained by cold pressing at a pressure of 600 MPa followed by vacuum sintering. The concentration inhomogeneity of Cr, Co, Mo, Sm was determined after 12 different sintering modes. A model of diffusion homogenization of ridge alloys, which allows to numerically evaluate the effect of sintering modes on the concentration inhomogeneity, was plotted. The distributions of chromium, cobalt, and molybdenum correspond to the asymptotically logarithmically normal law. Samarium is unevenly distributed in the structure. The effect of samarium additions on the magnetic properties of the alloy has been demonstrated. The alloying of 22Kh15K4MS alloy with 0.5 wt. % of samarium allows to obtain powder hysteresis magnets with a coercive force in the range from 3.9 to 33.0 kA/m and a residual magnetic induction from 0.44 to 0.95 T.

The dependence of the ignition temperature, combustion rate and composition of the resulting products on the concentration of Ti + C in mixtures with powder of a high-entropy alloy (HEA) FeNiCoCrCu and the initial mixture of metals forming it (MIX) has been studied. HEA was obtained by mechanical activation (MA) of a mixture of metal powders in argon. At the melting temperature, the high-entropy FeNiCoCrCu alloy decomposes into several phases, but the basis of the HEA alloy, as well as the alloy obtained by melting and crystallizing MIX, is a 5-component phase with an average formula Cu1.2Fe1.4Ni1.4Co1.4Cr. In addition, 5, 4, and 3-component phases with averaged formulas Cu2Ni2Co2Fe2Cr, Cu3Ni3Co2.9Fe2.5Cr, Cu4.8Ni4.5Co4.6Fe4.2Cr, Cu40Fe2Ni4Co2C, Cr12.5Fe3.2Co2.6Ni and Co3.2 Fe3,5 Cr are present in small amounts in the binder. Experiments on the ignition and combustion of mixtures of MIX and HEA with Ti + C were carried out in argon at atmospheric pressure. The combustion rate, ignition temperature, and maximum temperature reached in the thermal explosion of MIX and HEA mixtures with Ti + C increase with increasing Ti + C concentration. Due to the low exothermicity of the mixtures, the experiments were carried out at an initial temperature of 500 °С. At this initial temperature, the combustion limit of the samples occurs when the Ti + C concentration in the HEA and MIX mixtures is less than 30 %. Based on the results of scanning electron microscopy, the volume concentration of the number of titanium carbide (TiC) particles in molten samples was calculated. In an alloy with a HEA binder, the number of TiC particles per unit volume is 1.5-3.0 times greater than in an alloy with a MIX binder, and their size is correspondingly smaller. With an increase in the concentration of Ti + C from 30 to 40 % in a mixture with HEA, the number of TiC particles per unit volume decreases. In a mixture with MIX, the number of TiC particles per unit volume passes through a minimum. This is due to two opposite processes: on the one hand, the probability of the generation of TiC particles increases, on the other hand, their coagulation occurs.
Microstructure and phase composition of hard alloys produced from nanocrystalline powder mixture WC-6wt.%Co with C, Al and ZrC additives
Authors: Briakunov S. V. , Kurlov A. S.
Published: March 2023

A large specific surface area of WC nanopowder determines its high chemical activity and makes it very sensitive to various impurities, among which oxygen is most harmful and unavoidable. During heating, oxygen interacts with carbon of WC being removed in the form of CO/CO2, which finally leads to the appearance of embrittling η-phases in the hard alloy, abnormal growth of WC grains, and formation of a porous microstructure. To prevent heavy decarburization of WC during vacuum sintering of hard alloy from a nanocrystalline powder mixture WC-6wt.%Co, in this work we compared three methods: addition of extra carbon to compensate for carbon loss as a result of decarburization; addition of Al to bind impurity oxygen into Al2O3 before it interacts with carbon of WC; and addition of ZrC to compensate for carbon loss and bind impurity oxygen into ZrO2. Nanocrystalline powder mixtures based on WC-6 wt.%Co with and without additions of C, Al, and ZrC were prepared from microcrystalline powders of WC, Co, Al, ZrC, and carbon black by high-energy milling, then they were compacted in a cylindrical mold by uniaxial pressing at a pressure of ~460 MPa and sintered in graphite crucibles for 15 min at 1380 °C in vacuum of ~10-2 Pa. The heating rate to the temperature of sintering was 10 °C/min. The initial powders, powder mixtures prepared therefrom, and sintered hard alloys were certified using X-ray diffraction, chemical analysis, scanning electron microscopy, BET adsorption method, helium pycnometry, and Vickers method. The studies performed showed that the average particle size in all the prepared powder mixtures does not exceed 100 nm, and the content of impurity oxygen in them varies from 3.3 to 4.3 wt.% depending on the additives. It was established that only a part of oxygen contained in the powder mixtures is in the chemisorbed state and takes part in the decarburization of WC during vacuum sintering. The Al additive is completely oxidized during milling of the powder mixture and transforms into nanocrystalline Al2O3, which only aggravates carbon loss during sintering and results in the formation of a multiphase and relatively porous microstructure of the hard alloy. On the contrary, using carbon and ZrC additives we managed to prevent the decarburization of WC during sintering of the hard alloy and to form a less porous microstructure in it. It was shown that the presence of ZrO2 inclusions does not impede intensive growth of WC grains during sintering, but rather promotes it. Carbon deficit slightly suppresses intensive WC grain growth during sintering of hard alloy leading to the formation of η-phases and to an increase in the density and microhardness, but the presence of oxide inclusions Al2O3 and ZrO2 in the microstructure reduces the values of these properties.
Obtaining and properties of rolled products from clad powders NPG-80 and Nibon-20
Authors: Mal'tsev I. M. , Getmanovsky Yu. A.
Published: March 2023

Antifriction tape sealing materials (TSM) are used in the manufacture of turbines. This work studied the mechanism of the increase in thickness of rolled products. The study showed that internal oxides of powder particles, which are reduced during sintering and annealing in hydrogen, cause a change in the size of tapes and compacts from NPG-80 and Nibon-20 clad powders. The distinctive feature of powders used in the work is the presence of a nickel shell around the particle of the solid lubricant (graphite or boron nitride). It was shown that an increase in sintering temperature and heating time to isothermal holding intensifies the growth of the tapes and samples The studies carried out point to a relationship between reduction processes occurring in hydrogen during heating, sintering, and annealing of NPG-80 and Nibon-20 powders with an increase in the thickness of the tape containing the solid lubricant in its composition. An increase in the duration of heating to isothermal holding at 1150 °C is accompanied by an increase in the thickness of rolled stock. Sintering of TSM Nibon-20 in the first mode (4 h to 1150 °C) gives an increase in thickness by 5-7 %, whereas sintering in the second mode (9 h to 1150 °C) gives an increase of 12-13 %. For NPG-80, the increase in thickness is 3-7 % and 8-11 %, respectively. This leads to some decrease in the physical and mechanical properties of TSM. Lower temperatures and higher heating rates are recommended for the sintering of sheet materials from NPG-80 and Nibon-20 in the hydrogen atmosphere. The increase in thickness of TSM from clad powders NPG-80 and Nibon-20 can be avoided if the sintering (heating) is carried out under pressure. By the method of electric rolling and subsequent hot rolling TSM is obtained from Nibon-20.
Comparative analysis of the tool life of submicron hard alloy WC-10Co sintered from powder obtained by electro discharge in oil
Authors: Dvornik M. I. , Vlasova N. M.
Published: March 2023

In this paper, comparative studies of the microstructure, mechanical characteristics and service life of a cutting insert made of submicron cemented carbide WC-10Co, obtained as a result of recycling VK10 cemented carbide by Electro Discharge Erosion (EDE) in oil, were carried out. The specific energy consumption directly for the formation of pulses in the process of EDE is to a relatively small value (5.7 kW·h/kg). Excess carbon formed as a result of oil pyrolysis during EDE was removed by heat treatment. The granulometric composition of the obtained powder and the microstructure of the particles were studied. It is shown that the particles of the resulting powder consist of plate-like WC grains with an average diameter of 0.46 pm and interlayers of cobalt. The WC-10Co cutting insert, obtained by sintering this powder in vacuum, was used for a comparative analysis of service life during fine turning of aluminum alloy D16T. As objects for comparative analysis, cutters equipped with blades made of industrial alloys VK8 and VK6OM of a similar design were used. The microstructure and mechanical characteristics of the experimental alloy and the analogues presented have been studied. On the basis of studies of the microstructure and chemical composition of the back surface of the cutting inserts, the wear mechanism of the cutters was analyzed. It is shown that the hardness of the alloys has the main effect on their wear resistance when cutting an aluminum alloy with the presented cutters. The influence of the hardness of the cutters on the surface roughness of the resulting part was also studied. The obtained submicron cemented carbide WC-10Co exhibits the highest hardness (1590 HV) and wear resistance of the presented samples due to the smallest WC grain diameter (0.59 pm).

El cambio de paradigmas que trajo consigo el posestructuralismo en el campo de las relaciones internacionales permitió que las reflexiones académicas se enmarquen en nuevas perspectivas, dando lugar a una evolución paulatina. Sin embargo, el constructivismo posestructuralista no ha sido lo suficientemente valorado por parte de los académicos internacionalistas para tratar una problemática actual: la emergencia de China en el sistema internacional. La mayoría prefiere trabajar desde teorías objetivas de la realidad, dando relevancia a los aspectos económicos en las relaciones internacionales y en el estudio de las relaciones sino-latinoamericanas. A diferencia de las investigaciones hechas hasta ahora sobre China y Latinoamérica, esta trabaja desde una argumentación fresca y diferente. Los aportes teóricos de Michel Foucault hacen posible una reflexión sobre estas relaciones desde otra mirada.

Статья посвящена исследованию организации деятельности структурного подразделения университета на примере Российского университета дружбы народов.

Целью анализа явилось описание принципов построения долгосрочной программы развития университета с опорой на основное структурное подразделение вуза — кафедру — в условиях возрастающей конкуренции на рынке образовательных услуг и стремления роста в глобальных рейтингах университетов мира.

Методологическую базу исследования составляют базисные аспекты концепции устойчивого развития. Было проведено самообследование деятельности вуза по ключевым индикаторам в следующих направлениях: организационная, учебная, научная, воспитательная деятельность. Полученные итоги были рассмотрены с точки зрения их связи с деятельностью кафедр университета. На организационном уровне описаны направления деятельности: управление планированием, расстановкой, мотивацией и эффективностью деятельности персонала. Особое внимание уделено таким аспектам работы кафедр, как вовлечение студентов-бакалавров, магистров и аспирантов в научную деятельность кафедры, возрастание публикационной активности сотрудников, интернационализация как характеристика современного высшего образования, а также работа над созданием и развитием корпоративной культуры вуза и имиджа кафедры, в том числе связь имиджа структурного подразделения с таким явлением университетской науки, как феномен научной школы университета.

Результаты исследования подтвердили гипотезу о том, что основные аспекты долгосрочной политики устойчивого развития вуза реализуются на уровне структурного подразделения университета.

Перспективы исследования заключаются в создании алгоритма построения программы устойчивого развития на уровне структурных подразделений вузов.

This work was carried out based on an analysis of the assessment made by students in the Institutional Scholarship Program for Teaching Initiation in Biological Sciences (PIBID) at the Universidade Federal de Lavras - MG (UFLA), where they presented their insights about the movie “Brave New Land” (Brava Gente Brasileira). The objective was to seek elements that demonstrate how the film dialogues with sociocultural and environmental issues, promoting addition to the training of biology teachers. With this goal, we used qualitative research that fits the content analysis, categorizing these students' common statements. We found 5 categories exposed in a frame, where we noticed how sociocultural issues stand out, however, the film brings relevant considerations about the Pantanal environment and the relationship between the traditional peoples with this place. Thus, it is possible to conclude that cinematographic art manages to dialogue and build a critical view of the relationships of the most diverse cultures with the collective and the environment.
SARS-CoV-2 inactivation and scRNAseq sample preparation protocol v2
Authors: M Osborn Raven
Published: March 2023

Coronavirus disease (COVID-19) is an infectious disease caused by the SARS coronavirus 2 (SARS-CoV-2) virus. Direct assessment, detection, and quantitative analysis using high throughput methods like single-cell RNA sequencing (scRNAseq) is imperative to understanding the host response to SARS-CoV-2. One barrier to studying SARS-CoV-2 in the laboratory setting is the requirement to process virus-infected cell cultures, and potentially infectious materials derived therefrom, under Biosafety Level 3 (BSL-3) containment. However, BSL3 laboratory facilities are rare and only a subset of these facilities are outfitted with the equipment needed to perform high-throughput molecular assays. Here, we describe a method for preparing non-hazardous RNA samples from SARS-CoV-2 infected cells, that enables scRNAseq analyses to be conducted safely in a BSL2 facility – thereby making molecular assays of SARS-CoV-2 cells accessible to a much larger community of researchers. (The last step in this version contains a supplemental video with extra context and tips, as part of the protocols.io Spotlight series, featuring conversations with protocol authors.)

Este libro aporta a la comprensión cabal del acto de la evaluación y su relación con el instrumento tradicionalmente utilizado para ello. Este no busca descalificar la evaluación como un proceso administrativo posible o necesario, ni quiere objetar el uso de herramientas tradicionales para tal efecto. Esta investigación busca, ante todo, generar conocimientos enseñables y transferibles a la formación de administradores, para que comprendan, de manera más humanizada, el acto de evaluar. Paradojas del reconocimiento en la evaluación del desempeño… aporta al conocimiento administrativo la idea de que es necesario sobreponerse a las trampas que el reduccionismo del conocimiento tradicional positivista impone por la cortedad de sus miras y sus métodos. Sugiere que es necesario superar las paradojas abriéndose a esa otra gran esfera del fenómeno de la evaluación que permanece oculta para el investigador y el evaluador positivista: el reconocimiento como necesidad humana fundamental.

The article describes the history of the development of geophysical methods in archaeological studies in Europe, the USA, the former USSR and Ukraine. In the 1950s the researchers quickly proceeded from the first sampling to the mass magnetic and electric measurements. In the 1980s there was a transition to digital registration during field studies, as well as rapid development of data processing. This led to the introduction of some geophysical methods in archaeology, which require complex calculations when processing the signal and inversion of data, such as georadar method, electrical resistivity tomography, induction method, etc. At the current stage, there is a need to interpret these more and more detailed and largescale geophysical data in the context of the differentiation of more and more weak in contrast physical properties, and small-scale inhomogeneities in the soil cover. Confirmation of the anthropogenic and technogenic occurrence of geophysical anomalies is searched for using direct measurement and modeling of physical parameters of soil and archaeological materials. The work also presents the achievements of domestic geophysicists, as they became the basis for the great modern archeological projects and made the archeological geophysics the fundamental part of the cultural heritage research in Ukraine.

The article is devoted to the elucidation of experimentally tested methods for correcting the frequency range, amplitudes and noise levels for seismic sensors. Increasing the level of sensitivity of the registration system in a certain frequency range allows flexibly and in a short time to study the timing of microearthquakes in different geological structures and assess seismic parameters, control the development of natural karst phenomena and man-made cracks and deformations. The method of expanding the limits of application of common seismic transmitters type SM-3 and (SM-3 KV) in the seismic channels of portable seismic stations used in Ukraine is presented to solve a number of problems of seismology in technogenic-loaded regions with a high level of industrial average daily noise components. The article presents some results of registration of seismic signals performed by the information collection system using additional corrected seismic sensors SM-3 with extended frequency range in the low frequency range of the spectrum 0.1–3 Hz, installed at Carp-Lviv-2.

A geoecological maps quality assurance scheme during the map life cycle has been developed. The main methodological tools of research are conceptual modeling and the method of expert assessments. The work traces approaches to the formation of map quality concepts and their evaluation: utilitarianism, consequentialism, welfareism, the principle of ecological value. The importance of ensuring the quality of geoecological maps at all stages of the product's life cycle has been given. The main methodological technique is the developed algorithmic model. The approaches, algorithm and groups of criteria for the quality of geoecological maps researching are defined: the internal quality of map data (from the producer's point of view), indicators of the external quality of maps (from the consumer's point of view), in particular technological, consumer criteria, scientific and social value of maps. In the course of experimental studies, a methodology for evaluating a number of consumer characteristics of geoecological maps was proposed. The expert analysis of the factors affecting the assessment of maps quality has been conducted. The hierarchy of the factor importance is built in the following sequence: effective color use, sufficient contrast of the image, composition (size and placement of map elements), text on a map. The work formulates features of ensuring the quality of geoecological maps during their creation and increasing the efficiency of their use. Prospects for the further assurance development lie in the deepening of the integral theory of the assessment of the quality of maps focused on the application of a propositional scheme for the assessment of various groups of maps.
