Background of the topic: Triclosan is a widely used antimicrobial agent in personal care products. Triclosan is readily absorbed into the skin and present in the human tissues and fluids.   But the triclosan showed many side effects including carcinoma. Therefore the determination of triclosan in various personal health care products by simplest analytical methods is very much significant. 
Purpose of the study: The present study was aimed to do the comparative evaluation of triclosan in selected soaps and the evaluation was carried out by using ultraviolet spectroscopy.
Methods: Comparative evaluation of the selected four anti-bacterial soaps were carried out and the percentage of triclosan was determined by calibration curve method. The analytical technique used was ultra-violet spectroscopy by using the solvent ethanol. The Linearity was tested using the standard triclosan in the range of 300 µg/ml - 1500 µg/ml.   The validation methods such as ruggedness, repeatability, intermediate precision, linearity were done for all the four selected samples. Accurately weighed soap samples and dissolved in 3 ml of water. Transferred this solution into a separating funnel and extracted with chloroform. Organic layer was separated out and pipette out 1 ml of this organic layer and diluted to 10 ml with ethanol. The absorbance of the sample solution was measured at 307 nm.
Results: Comparative evaluation of the selected anti bacterial soaps and triclosan content was estimated by UV-spectroscopy. The λmax was found to be 307nm. The method was found to be linear within 300 µg/ml - 1500 µg/ml.  The percentage of triclosan present in selected four samples A, B, C and D were 0.28±0.8772, 0.24±0.9878, 0.32±1.123 and 0.73±0.9932 respectively. 
Conclusions: The percentage of triclosan in sample A sample B were within the limit and sample C and sample D slightly higher than that of the safe limit. The method used for the estimation of triclosan was UV spectroscopy method which was validated using ICH guidelines.

The paper presents the formulation of the problem of optimizing the shape of the barrel on the basis of mathematical modeling of the firing process from an automatic 30-mm cannon. The work considers both the standard annular section of the trunk and with stiffeners of two types. The oscillation amplitude was chosen as the objective function of the minimization algorithm. The maximum mass of the trunk and the minimum allowable thickness of the trunk, determined in accordance with the theory of the greatest deformations, were chosen as restrictions. For a standard barrel with an annular cross-section, the external diameters of the barrel were controllable, for barrels with stiffeners past the diameters, the distances to the stiffeners and their size were taken into account. The problem of internal ballistics in the thermodynamic formulation was solved to determine the gas-noise parameters inside the barrel. Muzzle vibrations were determined on the basis of solving the problem of the stress-strain state of the barrel in a one-dimensional formulation, taking into account technological irregularities and the interaction of the projectile with the barrel. The search for the optimal shape of the trunk was carried out by the Nelder-Meade method, restrictions were taken into account using the penalty function method. The results of optimizing the shape of the trunk are presented in graphical and tabular form. The scattering of shells for the barrels of the considered cross-sectional shapes is determined. As a result of optimization, it was possible to increase the accuracy of shooting by more than 2 times.
DEVELOPING A SYSTEM OF EXPERT ASSESSMENT OF THE DEVELOPMENT AND ENVIRONMENTAL AND TECHNOLOGICAL MODERNISATION PROJECTS IN INDUSTRY
Authors:   Research Institute “Environmental Industrial Policy Center”, Volosatova A.A.
Published: April 2024

The article presents new approaches to the development of a system for the expert evaluation (peer review) of technological development and industrial modernisation projects aimed at increasing production resource efficiency and environmental performance and reducing carbon intensity. The relevance of the study is determined by the need to set uniform criteria and develop an integrated system for evaluating projects. It is emphasised that the Russian Federation has objectives to expand technological capabilities of the economy and ensure the growth of the domestic industry while improving the resource and reducing the negative environmental impact. These objectives are achieved through the development and implementation of innovative technological solutions, the transition to the best available techniques (BAT) and the formation of a circular economy. Both the state and business allocate significant funds to the industrial environmental and technological modernisation projects. Authors substantiate their position and emphasize that in order to provide support for priority areas of industrial development, it is necessary to develop objective criteria for assessing resource efficiency and environmental performance, as well as to develop a system of expert evaluation of projects. They propose to form a unified system of criteria for pre-financial evaluation of projects based on indicators characterising BAT, including indicators of environmental efficiency (air emissions and water discharges of pollutants), as well as resource intensity and carbon intensity of production. At the same time, the system of expert evaluation of projects should include tools for voluntary (at the stage of selecting technological solutions, developing projects and preparing documentation) and mandatory assessment (at the stage of considering projects by authorised executive authorities, commissions, banks, etc.). Authors demonstrate advantages of the system of expert evaluation of projects for environmental and technological modernisation of industry running a comparative analysis of the cement production projects. They conclude that using uniform criteria will allow taking into account the consistent improvement of the BAT, expanding the spectrum of areas of BAT application and clarifying (tightening) industry indicators, as well as international approaches to the evaluation of green projects. It is recommended using approaches worked out in the Russian Federation for strengthening Eurasian integration in the field of sustainable (including green) development.

Published: April 2024

The backpack used commonly affects posture and physical performance, resulting in increased oxygen uptake and energy expenditure. The purpose of this study is to confirm the effect of the chest loads on the reaching time of the cardiopulmonary response. Seventeen healthy men participants were monitored for cardiopulmonary function continuously during walking exercise with the Ramp protocol and recorded the time taken to reach THR, VO2 peak, RR Difference, maximal METs, maximal FECO2, and minimum FEO2. During the exercise test, subjects were instructed to carry a backpack loaded at no load, 5%, 10%, and 15% body weight in random order. There was a significant difference in the time to reach the THR, the oxygen intake peak time, the maximum metabolic equivalent time, the respiratory rate increase, the minimum oxygen amount, and the maximum carbon dioxide amount at no load and more than 5% load. However, no significant difference was found between the loads. It is thought that even a 5% backpack load of one's body weight can impose on cardiopulmonary energy costs, and this is thought to help improve training programs with a gradual increase in mechanical chest load.
A systematic evaluation of text mining methods for short texts: Mapping individuals’ internal states from online posts
Authors: Macanovic Ana , Przepiorka Wojtek
Published: April 2024

Short texts generated by individuals in online environments can provide social and behavioral scientists with rich insights into these individuals’ internal states. Trained manual coders can reliably interpret expressions of such internal states in text. However, manual coding imposes restrictions on the number of texts that can be analyzed, limiting our ability to extract insights from large-scale textual data. We evaluate the performance of several automatic text analysis methods in approximating trained human coders’ evaluations across four coding tasks encompassing expressions of motives, norms, emotions, and stances. Our findings suggest that commonly used dictionaries, although performing well in identifying infrequent categories, generate false positives too frequently compared to other methods. We show that large language models trained on manually coded data yield the highest performance across all case studies. However, there are also instances where simpler methods show almost equal performance. Additionally, we evaluate the effectiveness of cutting-edge generative language models like GPT-4 in coding texts for internal states with the help of short instructions (so-called zero-shot classification). While promising, these models fall short of the performance of models trained on manually analyzed data. We discuss the strengths and weaknesses of various models and explore the trade-offs between model complexity and performance in different applications. Our work informs social and behavioral scientists of the challenges associated with text mining of large textual datasets, while providing best-practice recommendations.
The phenomenon of laughter: mystery, news, affect
Authors: Bardinova S. S.,
Published: April 2024

The article reviews various theories of laughter on the basis of their conventionally accepted classification. Their substantive intersections, especially significant for A. F. Losev and L. V. Karasev, are revealed. This leads us to the conclusion that there can be as many emotions and meanings expressed by laughter as there are hypotheses about what laughter points to. This conclusion drew our attention to the essential qualities of laughter, regardless of its objects, forms, and purposes: virtuality and eventuality. The theories of M. Bakhtin, M. T. Ryumina, and G. Deleuze are considered in connection with these concepts. Specific attention is paid to the concept of laughter by J.-L. Nancy, which, while not excluding the ideas of the previously listed authors, as well as J. Derrida's and M. Heidegger's, is original in that it presents laughter as a presence, an autonomous event or affect, which is capable of being expressed in text and speech.

Published: April 2024

The aim of this study is to develop a valid and reliable scale to determine the reclusion tendency levels in adults. The sample group is consistent with adults between the ages of 18-60 (Mage=26.2 years; age range: 18-33 years). A literature review was performed and existing scales were examined prior to this study. Potential items were formed. Then the data collection using the template scale began. The collected data was used for exploratory and confirmatory factor analysis and for the purpose of testing the structural validity of the scale. As a result of the exploratory factor analysis, a measuring tool of 22 items consisting of four sub-dimensions of internal observation, spirituality, productivity, and autonomy sub-dimensions that explain the 58,51% of the total variations was formed. There is a meaningful positive correlation identified between the Reclusion Tendency Scale and the Preference For Solitude scale (r=.49; p <.001). The total reliability coefficient is calculated .92; .88 for “internal observation”, .88 for “spirituality”, .66 for “autonomy”, and .75 for “productivity” sub-dimensions. The findings from this study suggest that the reclusion tendency scale is a valid and reliable scale when tested in a sample of young adults.

TURKISMS – NAMES OF DAIRY PRODUCTS AND DISHES IN THE PHRASEOLOGY OF THE SOUTHERN SLAVS
Authors: Кузнецова И.В.
Published: April 2024

В работе рассматриваются южнославянские фразеологизмы с компонентом – названием молочных продуктов и блюд турецкого генезиса на фоне других языков. Ведущее место среди заимствований в языках большинства южных славян в силу исторических причин занимают османизмы (термин подчеркивает, что лексемы вошли в принимающие языки во время Оттоманской империи книжным путем или через устную речь). В результате длительного общения в быт и языки народов Южной Славии вместе с молочными продуктами и блюдами вошли их названия – калькированные и часто переоформленные в соответствии с нормами произношения языка-реципиента. Цель статьи – показать фразеопотенциал таких молочных продуктов и блюд, приготовленных на молоке, как каймак, йогурт, айран, сутлияш, в корпусах фразеологии Болгарии, Боснии и Герцеговины, Македонии, Сербии и Хорватии. Актуальность работы обусловлена необходимостью комплексного изучения фразеологии для выявления общего и идиоэтничного. Материал изучения – устаревшие и активно употребляющиеся в наши дни в некоторых регионах Южной Славии фразеологические единицы с тюркским компонентом заявленной тематики, взятые из фразеологических словарей и интернет-источников. Методы исследования – анализ компонентов, синхронно-описательный, сопоставительный. Структурно-семантические модели фразеологизмов и пословиц демонстрируют межъязыковую общность мотивационных идей и одновременно выявляемое на уровне образности специфичное.

The paper examines South Slavic phraseological units with the following component - the name of dairy products and dishes of Turkish origin against the background of other languages. The leading place among loanwords in the languages of the majority of the Southern Slavs due to historical reasons is occupied by Ottomans (the term emphasizes that lexemes entered the host languages during the Ottoman Empire by book or oral speech). As a result of long-term communication, the everyday life and languages of the peoples of South Slavia, along with dairy products and dishes, included their names – calcified and often re-formed in accordance with the norms of pronunciation of the recipient language. The purpose of the article is to show the phraseological potential of such names of dairy products and dishes prepared with milk as kaymak, yogurt, ayran, sutliyash in the phraseology of Bulgaria, Bosnia and Herzegovina, Macedonia, Serbia and Croatia. The relevance of the work is due to the need for a comprehensive study of phraseology to identify common and idioethnic. The material of the study is outdated and actively used nowadays in some regions of South Slavia phraseological units with a Turkic component of the declared topic. Research methods are component analysis, synchronous-descriptive, comparative. The structural and semantic models of phraseological units and proverbs demonstrate the interlanguage commonality of motivational ideas and specificity revealed at the level of imagery at the same time.

Занятия физической культурой в учебных заведениях являются основным пространством, где молодежь может и должна получать физическое воспитание. Эти занятия должны охватывать весь контингент обучающихся – и здоровых, и с нарушениями здоровья. Современные данные о состоянии здоровья студентов вузов России говорят о тенденции увеличения количества студентов, отнесенных по состоянию здоровья к специальной медицинской группе (СМГ). Статья посвящена разработке программы лечебной физической культуры для студентов специальной медицинской группы бакалавриата высших учебных заведений с учетом четырех нозологических подгрупп: 1) с заболеваниями сердечно-сосудистой системы; 2) с заболеваниями опорно-двигательной системы; 3) с заболеваниями органов дыхания; 4) с нарушениями зрения. Автором реализована программа лечебной физической культуры для студентов СМГ, состоящая из семи этапов, начиная с анализа медицинского состояния студентов СМГ и формирования нозологических подгрупп и заканчивая разработкой универсальных упражнений для каждой подгруппы. В статье представлены результаты анализа состояния здоровья студентов СМГ, на основе которых выявлены основные группы заболеваний. Предложены формы физических упражнений с учетом выявленных заболеваний и методы диагностики функционального состояния студентов до и после занятий (проба Штанге, проба Генчи, частота сердечных сокращений (ЧСС), объем жизненной емкости легких (ЖЕЛ)).

Physical education classes in educational institutions are the main space where young people can and should receive physical education. These classes should cover the whole contingent of students – both healthy and with health problems. Modern data on the state of health of Russian university students show a tendency to increase the number of students classified as a special medical group (SMG) for health reasons. The article is devoted to the development of a therapeutic physical training program for students of the special medical group of undergraduate students of higher educational institutions taking into account four nosological subgroups: 1) with diseases of cardiovascular system; 2) with diseases of musculoskeletal system; 3) with diseases of respiratory organs; 4) with visual impairment. The author implemented a program of therapeutic physical training for SMG students, consisting of seven stages, starting with the analysis of the medical condition of SMG students and formation of nosological subgroups and ending with the development of universal exercises for each subgroup. The article presents the results of analyzing the health status of SMG students, on the basis of which the main groups of diseases were identified. The forms of physical exercises taking into account the identified diseases and methods of diagnostics of the functional state of students before and after classes (Stang test, Henchey test, heart rate (HR), vital capacity of lungs (VCL)) are proposed.

В статье рассматривается проблема формирования этнокультурной компетентности студентов разных национальностей в условиях поликультурной образовательной среды современного вуза. Актуальность исследования обусловлена Стратегией государственной национальной политики Российской Федерации на период до 2025 года (в редакции Указа Президента Российской Федерации от 06.12.2018 № 703), в которой указаны цели государственной национальной политики: «гармонизация межнациональных (межэтнических) отношений; успешная социальная и культурная адаптация иностранных граждан в Российской Федерации и их интеграция в российское общество» [10]. Обосновываются научные подходы, направленные на формирование у студентов разных национальностей этнокультурной компетентности как основы, обеспечивающей каждому студенту равные возможности для личностного и профессионального развития, выбора жизненных приоритетов в гармонии этнического и общечеловеческого. Исследование проведено в вузе, в котором обучаются студенты разных национальностей, в том числе из стран дальнего зарубежья. Поэтому в данной статье раскрывается значение поликультурной образовательной среды как необходимой основы гармонизации этнических межличностных отношений. Для достижения этого важнейшим условием определена реализация в образовательном процессе культурологического, этнокультурного и межличностного подходов, а также диалога культур как механизма осуществления равноправных взаимоотношений в процессе межкультурного общения.

The article discusses the problem of formation of ethnocultural competence of students of different nationalities of a modern university in a multicultural educational environment. The relevance of the study is due to the Strategy of the State National Policy of the Russian Federation for the period up to 2025 (as amended by the Decrees of the President of the Russian Federation dated 06.12.2018 No. 703), which specifies the goals of the state ethnic policy of the Russian Federation: “harmonization of interethnic relations; successful social and cultural adaptation of foreign citizens in the Russian Federation and their integration into Russian society” [10]. The article substantiates scientific approaches aimed at the formation of ethnocultural competence by students of different nationalities as the basis that provides each student with equal opportunities for personal and professional development, the choice of life priorities in the harmony of the ethnic and universal. The study was carried out at a university where students of different nationalities, including those from foreign countries, study, hence the importance of a multicultural educational environment as a necessary basis for harmonizing ethnic interpersonal relations. To achieve this, the most important conditions are the following: the implementation of culturological, ethnocultural and interpersonal approaches in the educational process, as well as the dialogue of cultures as a mechanism for the implementation of equal relations in the process of intercultural communication.

Published: April 2024

Background: Inflammatory biomarkers, such as the neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR), serve as valuable prognostic indicators in various cancers. This multicenter, retrospective cohort study assessed the treatment outcomes of lenvatinib in 71 patients with radioactive iodine (RAI)-refractory thyroid cancer, considering the baseline inflammatory biomarkers.Methods: This study retrospectively included patients from five tertiary hospitals in Korea whose complete blood counts were available before lenvatinib treatment. Progression-free survival (PFS) and overall survival (OS) were evaluated based on the median value of inflammatory biomarkers.Results: No significant differences in baseline characteristics were observed among patients grouped according to the inflammatory biomarkers, except for older patients with a higher-than-median NLR (≥2) compared to their counterparts with a lower NLR (P= 0.01). Patients with a higher-than-median NLR had significantly shorter PFS (P=0.02) and OS (P=0.017) than those with a lower NLR. In multivariate analysis, a higher-than-median NLR was significantly associated with poor OS (hazard ratio, 3.0; 95% confidence interval, 1.24 to 7.29; P=0.015). However, neither the LMR nor the PLR was associated with PFS. A higher-than-median LMR (≥3.9) was significantly associated with prolonged OS compared to a lower LMR (P=0.036). In contrast, a higher-than-median PLR (≥142.1) was associated with shorter OS compared to a lower PLR (P=0.039).Conclusion: Baseline inflammatory biomarkers can serve as predictive indicators of PFS and OS in patients with RAI-refractory thyroid cancer treated with lenvatinib.
Treatment of Hypoparathyroidism by Re-Establishing the Effects of Parathyroid Hormone
Authors: Rejnmark Lars
Published: April 2024

The conventional treatment of hypoparathyroidism (HypoPT) includes active vitamin D and calcium. Despite normalization of calcium levels, the conventional treatment is associated with fluctuations in calcium levels, hypercalciuria, renal impairment, and decreased quality of life (QoL). Replacement therapy with parathyroid hormone (PTH)(1-84) is an option in some countries. However, convincing beneficial effects have not been demonstrated, which may be due to the short duration of action of this treatment. Recently, palopegteriparatide (also known as TransCon PTH) has been marketed in Europe and is expected also to be approved in other countries. Palopegteriparatide is a prodrug with sustained release of PTH(1-34) designed to provide stable physiological PTH levels for 24 hours/day. A phase 3 study demonstrated maintenance of normocalcemia in patients with chronic HypoPT, with no need for conventional therapy. Furthermore, this treatment lowers urinary calcium and improves QoL. Another long-acting PTH analog with effects on the parathyroid hormone receptor (eneboparatide) is currently being tested in a phase 3 trial. Furthermore, the treatment of autosomal dominant hypocalcemia type 1 with a calcilytic (encaleret) is also being tested. All in all, improved treatment options are on the way that will likely take the treatment of HypoPT to the next level.
Simulation of the Evolution of Cross-Shore Beach Profiles using SBEACH Modelling
Authors: L. Hackett Michael
Published: April 2024

Coastal erosion significantly threatens sandy beaches worldwide, impacting coastal communities and ecosystems. This research investigates the application of SBEACH (Storm-induced BEAch Change), a numerical beach modelling computer programme, as a tool for coastal engineers to predict beach profile evolution in response to wave and tidal actions. The study used SBEACH simulations to explore the equilibrium beach profiles under varying conditions, including wave height, wave period, sediment grain size, and beach slope. This study also examined the effects of storm tides on equilibrium profiles and proposed protective sand dunes' dimensions to safeguard against storm surges. This research highlights SBEACH's potential as a valuable tool for assessing and planning coastal erosion mitigation strategies. While SBEACH provides insights into cross-shore beach profile dynamics, combining it with GENESIS offers a more comprehensive approach to coastal management. However, it is crucial to consider real-world engineering experience and safety factors when deciding on beach stabilisation and protection measures. Coastal countries can benefit from such modelling approaches to better manage and protect their sandy beaches, which play a crucial role in coastal defence and maintaining ecosystem integrity.

Increasingly, and often mutually conflicting requirements for the use of water resources, there is a need for more complex management methods, including the management of the volume of reservoirs. Silt filling of reservoirs is one of the most well-known problems of river hydraulics. Dams and reservoirs, created by damming river flows, cause the retention of river sediment (drag and floating sediment) that comes from the gravitating basins, or sub-basins of the reservoir's tributaries. By analyzing the sediment transport on the tributaries, and the total amount of sediment deposited in the Modrac multi-purpose reservoir, real data are obtained on the amount of sediment introduced into the Modrac multi-pupose reservoir, the dynamics of sediment input, and the degree of pollution of this type of water body. The Modrac multi-purpose reservoir is the only available water resource in the region of Tuzla and its surroundings. Acknowledging the fact that the useful volume of the reservoir is limited, and that over time the reservoir is filled with dragged sediment and coal dust as floating sediment, and that consumers - the population, industry and others must be provided with a water supply with a high degree of safety. Excess water needs to be used to the maximum for the purpose of electricity production, and there is a need to optimize the system, i.e. more efficient management of the water resources of the reservoir, i.e. to prove the maximum utilization of the reservoir while continuously providing all the necessary amounts of water to which the Modrac multi-purpose reservoir is connected.
Intermediate Gas Phases within Turbulent Radiative Mixing Layers
Authors: Blackburn Meg Georgina , Farber Ryan Jeffrey
Published: April 2024

Turbulent radiative mixing layers (TRMLs) occur ubiquitously in astrophysical environments; e.g., TRMLs are prevalent within galactic outflows at the intersections between hot supernovae ejecta and cold molecular clouds. A velocity shear between the rapidly outflowing hot gas and cold clouds drives the Kelvin–Helmholtz instability producing TRMLs, with radiative cooling dominating the heat transfer between the gas phases. Using hydrodynamic simulations, we have modeled TRMLs for a range of overdensities (100, 1000, 3000) applied to cold phase temperatures of 400, 103, and 104 K. The production of an intermediate gas phase at the interface between the hot and cold phases is consistently observed at ∼104 K for molecular clouds, in agreement with larger-scale wind-tunnel simulations.
The Hybrid Debris Disk Host Star HD 21997 is a High-frequency Delta Scuti Pulsator

Published: April 2024

HD 21997 is host to a prototypical “hybrid” debris disk characterized by debris disk-like dust properties and a CO gas mass comparable to a protoplanetary disk. We use Transiting Exoplanet Survey Satellite time series photometry to demonstrate that HD 21997 is a high-frequency delta Scuti pulsator. If the mode identification can be unambiguously determined in future works, an asteroseismic age of HD 21997 may become feasible.

Ultraviolet spectroscopy is a powerful method to study planetary surface composition through reflectance measurements, atmospheric composition through stellar/solar occultations, transits of other planetary bodies, and direct imaging of airglow and auroral emissions. The next generation of ultraviolet spectrographs (UVS) on board ESA’s Jupiter Icy Moons Explorer and NASA’s Europa Clipper missions will perform such measurements of Jupiter and its moons in the early 2030s. This work presents a compilation of a detailed UV stellar catalog, named Catalog of Ultraviolet Bright Stars (CUBS), of targets with high intensity in the 50–210 nm wavelength range with applications relevant to planetary spectroscopy. These applications include (1) planning and simulating occultations, including calibration measurements; (2) modeling starlight illumination of dark, nightside planetary surfaces primarily lit by the sky; and (3) studying the origin of diffuse Galactic UV light as mapped by existing data sets from Juno-UVS and others. CUBS includes observations from the International Ultraviolet Explorer (IUE) and additional information from the SIMBAD database. We have constructed model spectra at 0.1 nm resolution for almost 90,000 targets using interpolated Kurucz models (which have a resolution of 1 nm) and, when available, IUE spectra. CUBS also includes robust checks for agreement between the Kurucz models and the IUE data. We also present a tool for which our catalog can be used to identify the best candidates for stellar occultation observations, with applications for any UV instrument. We report on our methods for producing CUBS and discuss plans for its implementation during ongoing and upcoming planetary missions.

Este texto apresenta resultados de uma pesquisa qualitativa, a qual surge a partir das inquietações, referentes à docência nos Anos Iniciais, a fim de repensar as práticas pedagógicas no sentido de ampliar e indicar caminhos para estruturar o ensino na perspectiva da Alfabetização Científica - AC por meio de práticas de Modelagem nas Ciências - MC. Nesse sentido, apresentamos como objetivo compreender o entendimento sobre formação continuada a partir da fala de professoras dos Anos Iniciais. A constituição dos dados se deu por meio de entrevista semiestruturada realizada com três professoras que compõem o ciclo de alfabetização de uma escola da rede pública de ensino, localizada na região noroeste do Rio Grande do Sul – RS. O processo analítico seguiu os procedimentos da Análise de Conteúdo, a partir da qual reconhecemos duas categorias emergentes, as quais sinalizam para a formação continuada como: 1) necessidade pessoal e de qualificação profissional, denotando o caráter contínuo da aprendizagem docente e de transformação de saberes vinculados à melhoria dos processos de ensino e de aprendizagem e 2) tempo e espaço que possibilita reflexões sobre o trabalho docente, assinalando para uma perspectiva de prática reflexiva que, entretanto, ainda requer ações formativas para ser melhor desenvolvida.

A metodologia proposta consiste em três etapas principais: (i) preparação e organização, (ii) utilização do Diário de Bordo durante a aula e (iii) avaliação e feedback. O estudo de caso foi realizado em duas turmas, totalizando 84 alunos, na disciplina das aulas de Circuitos Digitais e Microcontroladores dos cursos integrados de Automação Industrial e Mecatrônica do Instituto Federal de Minas Gerais, campus Ibirité. A partir das avaliações dos alunos realizadas por meio de formulários, observou-se que a implementação dessa ferramenta teve diversos resultados positivos. Primeiramente, facilitou o desenvolvimento das habilidades de síntese e de organização dos alunos. Além disso, evidenciou a maior motivação e comprometimento dos alunos durante as aulas. A ferramenta também se mostrou uma avaliação processual, possibilitando momentos personalizados de aprendizagem dentro das aulas. Esse recurso possibilitou ao professor identificar com rapidez e precisão o progresso de aprendizagem dos alunos, permitindo ajustes imediatos no conteúdo da aula. Além disso, o trabalho ressalta a necessidade de explorar novas estratégias de ensino especificamente adaptadas a disciplinas relacionadas à tecnologia.
