Published: August 2022

ABSTRACT Objectives: To evaluate the impact of social isolation due to SARS-CoV-2 on the prevalence and severity of urinary incontinence and how this correlates with the quality of life of the nulliparous women evaluated. Method: Observational, longitudinal study, carried out from August/2019 to September/2020, at the Faculdade de Ciências da Saúde do Trairi/RN, with 37 nulliparous women from 18 to 35 years old, who answered the socio-anthropometric assessment, to the Incontinence Severity Index Questionnaire and King’s Health Questionnaire, before and during isolation due to SARS-CoV-2. Statistical analysis: Wilcoxon test, and Spearman’s correlation coefficient. Significance level p≤0.05. Results: During social isolation, there was an improvement in urge incontinence (p=0.01) and in the frequency of urinary incontinence (p=0.03). The severity of urinary incontinence correlated with: general health perception (p=0.02; r=0.65); physical limitations (p=0.03; r=0.60); social (p=0.001; r=0.82). Conclusion: The social isolation from SARS-CoV-2 improved urge incontinence and frequency of urinary incontinence. The more severe the urinary incontinence, the worse the general health perception, physical and social limitations during isolation.

Published: August 2022

Dental implants are medical devices that are surgically inserted into the patient's jawbone by an orthodontist to act as roots of missing teeth. After the implantation, the maxilla or mandible integrates with the surface of the dental implant. This process, called "osseointegration," is an important period to ensure the long-term use of dental implants and prevent implant failures. Metal implants are the most used implant materials. However, they have disadvantages such as corrosion, metal ion release from metal implant surfaces and associated toxicity. To avoid these adverse effects and improve osseointegration, alternative dental implant materials such as ceramics, polymers, composites, and novel surface modification technologies have been developed. The safety of these materials are also of concern for toxicologists. This review will give general information about dental implant materials, osseointegration and successful implantation process. Moreover, we will focus on the new surface coatings materials for of dental implants and their toxicity and safety concerns will be discussed.

Published: August 2022

In the presented case, a typical example of CCHF is described, a patient who lives in an endemic territory and had risk factors for infection – cattle keeping and tick bite. The patient sought medical help in a timely mannert, but his diagnosis of CCHF was made late, due to underestimation of the risk factors for CCHF infection and non-use of the standard case definition. The correct diagnosis was made only after the appearance of the hemorrhagic syndrome. The appearance of bleeding in patients with CCHF presents a high risk of infection for others. But timely isolation and intensive treatment allowed for the prevention of infection of contact persons and save the patient’s life.

Authors: Paula G Santos , Francisco JR Paumgartten , Antonio C Siani
Published: August 2022

Monoterpenes with p-menthane structure (perillyl series) can inhibit Ras-proteins prenylation involved in carcinogenesis processes. To evaluate the safety and efficacy of perillyl alcohol (POH) and limonene to treat any type of human cancer, we conducted a systematic review of clinical studies found in seven biomedical bibliographic databases and four clinical trial registries. After screening titles, abstracts, and full texts for inclusion/exclusion criteria, one study on limonene (oral) and 19 on POH administered by oral (13), dermal (2), or intranasal-instillation routes (4), comprising phase I or I/II trials, were included in the review. The quality of included studies was assessed as well. No randomized and controlled phase-III trial was performed or is in progress. A critical appraisal of study results suggested that both compounds are safe after oral ingestion, dermal application, or nasal instillation. Overall, phase II studies showed no evidence of anticancer activity. Nasal instillation of POH, however, apparently prolonged the overall survival of patients with glioblastoma. Randomized and controlled (phase III) clinical studies are necessary to confirm these findings.

The road network is an important part of the transport system that ensures the operation of all industries, agriculture and social sphere. Road maintenance costs can be from 5 to 10% of the state budget per year. On the other hand, it should be noted that vehicle owners make significant contributions to the state budget of Ukraine through direct and indirect taxes. The road network has a lot of problems in terms of efficient functioning. One of the main problems is insufficient financing of road repair works. The aim of the study is to determine the spatial features of the road network of Western Ukraine, and the main task - to analyze, based on open data OpenStreetMap, the accessibility of the road network in the context of regions, districts and cities of regional subordination of Western Ukraine using the indicators the transport network density and the Engel’s coefficient. Due to the difficulty of accessing official statistics at the local level, both official statistics and open data from the OpenStreetMap mapping service were used. As a result of the research it was revealed: relatively even distribution over the territory, lack of sharp fluctuations in the availability level (the maximum and minimum value of the Engel’s coefficient differs only by 5.7 times); the most important roads (primary and secondary) connect regional centers and the largest cities with each other and with the state border; the largest road hub in Western Ukraine is the city of Lviv; among the districts, the highest accessibility of roads is observed in the western part of Volyn oblast, western and central parts of Chernivtsi oblast and southern part of Rivne oblast; increased concentration of roads in Precarpathian (an area of old industrial development); reduced concentration in the Ukrainian Carpathians and in the northeast of the region (north of Rivne region). In general, at the local level (districts, cities of regional subordination) the same patterns can be observed as at the regional level (regions).

Published: August 2022

This article is devoted to the socio-geographic assessment of the problems and prospects of tourism development in the city of Volodymyr. The choice of the case study city is due to the active processes of forming the brand of the city of Volodymyr, which have been observed in recent years, as well as its border economic and geographical location. The authors characterized the infrastructure of tourism as a factor in the development of the city territory, as well as considered modern approaches to the formation of the tourist attraction of the city territory. The article describes the methodical aspects of the evaluation of the city's tourist sphere, gives a detailed description of the tourist resources and tourist infrastructure of the city of Volodymyr, as well as reveals the essence of branding and promotion of the city. The article presents an assessment of the state of the tourist sphere of the city of Volodymyr by internally displaced persons, namely tourist facilities, transport, accommodation and catering facilities, ATMs, shopping centers and sanitary infrastructure facilities (public toilets). With the help of the SWOT analysis method, the authors identified promising directions for optimizing the city's tourist attractiveness and proposed a number of main guidelines for the strategic development of the city's tourist sphere: further development of cultural and historical tourism; development of tourist and related infrastructure; activation of advertising and image work at the international level to attract foreign guests; attraction of grant support for the development and restoration of architectural monuments; development of educational tourism. The conducted research proved that tourism as a branch of activity can act as one of the main effective factors of socio-economic development of the territory.
TRANSITION AND URBAN TRANSFORMATIONS IN POST-SOVIET PERSPECTIVE: APPROACHES AND CONCEPTUALIZATION
Authors:   Taras Shevchenko National University of Kyiv, DENYSENKO Olena
Published: August 2022

This paper explores current debates on post-socialist transition and transformations, focusing on their spatial dimension and conceptualization of the urban transformations. We analyze the evolution of approaches and current discussions around transition as such and post-socialist transition in particular, the relationships between transition and transformations along with their spatial outcomes, and define the main types of restructuring in the course of spatial transformations. In this paper, we illustrate transition as temporal and methodological frame and provide an overview of ideas on its ending, relevance and usefulness, interpreting post-socialist transition as fundamental societal changes of political regime, economy, institutions and space, which are taking place simultaneously. We argue that urban transformations as spatial projection and outcome of the post-socialist transition could be interpreted through the lens of restructuring – the process of socialist structures updating under which old structures are transforming, supplementing with new elements, and therefore new structures are gradually developing as a reflection of the new ideologies and spatial practices. We distinguish and analyze three main types of urban space restructuring in the post-socialist perspective - functional, morphological and institutional, which, interacting, illustrate the key changes of the post-socialist urban spaces. Such interpretation of spatial transformations could be useful for understanding different dimensions of spatial dynamics, providing deeper contextualization and giving comparative perspective on spatial outcomes.
FEATURES OF THE URBAN AGGLOMERATIONS DEVELOPMENT IN THE CONDITIONS OF CONTEMPORARY GLOBALIZATION
Authors:   V. N. Karazin Kharkiv National University, Ukraine, KRAVCHENKO Kateryna
Published: August 2022

The intensity of globalization processes and the role of cities in the socio-economic development of countries and regions increase at the current stage of society's development. Agglomerations that have the status of the global (world) level play the most crucial role. he purpose of the paper is to analyze the impact of globalization processes on the peculiarities of the development of urban agglomerations in the conditions of contemporary globalization, as well as to identify problems and prospects for their further evolution. The research was carried out based on the system, synergistic, informational and human-geographical approaches; using the methods of induction and deduction, comparison, analogy, analysis, synthesis, systematization, as well as mathematical, statistical and cartographic methods. Three waves characterized the spread of globalization in historical retrospect: the first one (the first half of the 20th century) described the intensive development of cities and industry, the development of transport infrastructure; the second wave (the second half of the 20th century) marked the formation of transnational, transcontinental and global corporations, the transfer of "dirty" industries to the territory of poor third world countries; the third (the beginning of the 21st century – until now) characterizes the emergence of urbanization beyond geopolitical and administrative borders. A significant trend in the contemporary development of cities is the tendency towards developing urban agglomerations, increasing their importance in contemporary spatial transformations and processes taking place on the planet. Agglomerations within regions of the world arose quite unevenly. The largest number are in the USA, Europe, and Asia, and agglomerations are growing at an accelerated pace in Africa and Latin America. Until the 20th century, the large agglomerations were formed mostly in developed countries and regions of the world due to the available resource and economic potential. Now the processes of intensive agglomeration are characterized for cities and developing countries, where the number of agglomerations is increasing. A significant increase in the number of cities and agglomerations in countries with a low level of development leads to the emergence and aggravation of global problems of modern times.
Foreshock statistics and their possible relationship to earthquake prediction in the Italian region
Authors: Console R. , Murru M. , Alessandrini B.
Published: August 2022

This study focuses on the foreshocks of earthquake sequences recorded by the Italian national seismological network between 1975 and 1991. We consider as foreshocks events exceeding a given threshold magnitude that follow a period of quiescence and come before a mainshock occurring within a given time-distance range. The total number of potential foreshocks identified by the algorithm depends on the size and the duration of the predefined quiescence area, whereas the number of mainshocks preceded by foreshocks depends also on the size of the area in which the event is expected and the duration of the alarm period. Our aim was to optimize the choice of the parameters defining potential foreshocks as precursors of stronger earthquakes, in order to improve their validity and reliability.

A preliminary investigation carried over the whole Italian territory allowed the definition of zones where foreshocks-mainshocks series are likely to occur. One of these zones is an area of about 32,000 km2 in Central Italy including a total of 2671 events of M ≧ 2.5, where there is a significant tendency of moderate shocks to be followed at short distance and in short time by larger shocks. Our method would lead to issuing 63 alarms with the optimal definition of foreshocks as events of magnitude exceeding 3.0 after at least 80 days of quiescence in an area of 140 km radius. The rate of occurrence for mainshocks of magnitude exceeding 4.0 during the following 48 hours, in the specified area of 30 km radius, is 6 of 23 events. The corresponding probability gain is about 150. For comparison, another larger zone (Po Valley) with 453 events of M ≧ 2.5 exhibits only a rate of 1 of 82 precursors. In this area most events are single shocks. Our analysis shows that the foreshock activity can be regarded as a significant earthquake precursor, so suggesting that real time observation of seismicity can be used to improve the quality of an earthquake prediction system.

Published: August 2022

Non-fungible tokens (NFTs) have gained considerable media attention and sparked growing public interest. NFTs are unique units of data recorded on a permanent ledger or blockchain. NFTs are used to record ownership of both physical and digital goods. Prominent sport organizations have embraced NFTs for innovative growth opportunities such as generating revenue via novel digital products (e.g., digital collectibles). For example, the National Basketball Association (NBA) launched NBA Top Shot, an online marketplace to buy and sell digital sports highlights. Sport organizations are exploring future innovation opportunities where there is a need to reliably track and verify authenticity or ownership of digital or digitizable assets. This includes existing sport products (e.g., tickets) and novel fan engagement initiatives. To benefit from NFTs, sport managers need to reconceptualize how sport is marketed and managed in a digital domain. The purpose of this research primer is to acquaint readers with key concepts related to NFTs. Specifically, we provide an overview of NFTs, offer a review of the brief history of NFTs, conceptualize NFTs via parallels with collectibles, and address the speculative nature of the NFT market. We conclude by outlining innovative growth opportunities of NFTs for sport managers and future research directions for sport management scholars.

Head coaches play a crucial role in shaping both athletes’ athletic experiences and the complex team system. Consequently, coaching transitions have tremendous impacts on college athletes. Through the lens of transition theory, the purpose of this case study was to investigate the effect of multiple head coaching changes on NCAA Division I Power Five football athletes. Eight football athletes completed a 27-item open-ended questionnaire. Data analysis revealed three explicit, meaningful themes: support, achievement, and consistency. This study strived to assist athletic administrators and coaches in becoming increasingly aware of the potential impact that these abrupt coaching transitions can have on the athlete experience. Additionally, through the voices of the participants, this study attempted to assist college athletes in navigating a coaching transition.
Rethinking Disability Inclusion in Intercollegiate Athletics
Authors: Stokowski Sarah , O'Donnell Stephanie
Published: August 2022

As higher education continues to strive to be inclusive and accepting of all identities, the NCAA must reconsider some of its practices and policies surrounding disability. The NCAA has started to recognize the importance of varying abilities within specific policies and procedures but there is still improvement that must be made to achieve an equitable experience for all athletes. By incorporating universal design into the implementation of the NCAA’s missions and priorities of academics, fairness, and well-being, the NCAA must re-examine which athletes are being excluded by its practices. Within academic regulations, the NCAA must reconsider initial eligibility, minimum credit hour requirements, and progress towards degree. The NCAA seeks to create an atmosphere of fairness; however, the inclusion of varying ability levels is excluded throughout various statements, hiring practices, and how specific sports are played. The NCAA has made well-being a top priority but this cannot be achieved without representation and focus on disability identity. This implies that more funding and resources should be implemented to support the understanding of disability identity development and formation. It is time for the NCAA to rethink how disability can be included thoroughly throughout all aspects of collegiate sports.
Constructing Your Career Plays

Published: August 2022

The evolving landscape of job opportunities has led to increased concerns around life-career success of college student-athletes while and after they balance their academic and sport performance. At Kent State University (Division I) located in Kent, Ohio, Tracy Montgomery serves as the student-athlete career advisor liaison between Career Exploration & Development and the Department of Athletics. With more than 10 years of secondary education teaching experience and seven years of career advising/education, Tracy has identified and continues to apply Mark Savickas’s (2012, 2013) Career Construction Interview (CCI) as her most valuable tool in creating conversations around career development. In a sit-down interview with Tracy, she breaks down the life design technique (Savickas, 2015) so career practitioners and other intercollegiate athletic personnel may adopt the approach to support student-athletes to (a) identify what their intentions are toward life-career transitions; (b) realize why they perform their actions and closely hold their beliefs toward making life-career decisions ; and (c) move forward with how they can empower themselves to move in and out of “going pro.”

This zone is divided into four tectonic slices as Hopa-Borçka zone, Artvin Yusufeli zone, Olur Tortum zone and Erzurum Kars Ophiolite zone from north to south, east of the Eastern pontides, and the investigated rocks are located within the Olur-Tortum zone. These rocks are represented by dacites and rhyolites in the study area. Petrographically, it is observed in fine grained grayish, greenish, earthy colors. The main mineral contents are plagioclase, quartz and K-feldspars. Plagioclase, quartz and K-feldspars occur as phenocrysts, but are also observed in microlithic pastes. Plagioclases are characteristic with albite and polysynthetic twinning. Quartz is in the form of anhedral crystals and is distinguished from K-feldspars by its transparent colors in a single nicol.
Determination of Stoma Characteristics and SPAD Values of Some Local and Commercial Grape Varieties Cultivated in Kayseri Ecological Conditions
Authors: SÜMBÜL Ahmet
Published: August 2022

Abstract

This study was carried out to determine the leaf stoma characteristics and SPAD value of total 18 grape varieties (10 local and 8 commercial) grown in the Kayseri region. Among the varieties SPAD value ranged from 29.23 (Çekirdeksiz) to 42.26 (Kara Burcu), and the stoma frequency (stoma/mm2) ranged from 85.99 (Kara Burcu) to 136.83 (Tarsus Beyazı). Although there was a positive correlation between stoma width and stoma length, these parameters did not show a statistical correlation with stoma frequency. Stoma frequency and stoma surface showed a high positive correlation with both potential conductance index (r=0.76 and r=0.53, respectively) and relative stoma frequency (r=0.75 and r=0.65, respectively). Stoma shape coefficient showed a negative correlation with potential conductance index (r=-0.28). In this study, it was determined that the effect of the grape varieties on leaf stoma characteristics and SPAD value was important statistically. This result shows that leaf stomatal characteristics and SPAD value are genetically controlled.

Published: August 2022

The epidemiology of maxillofacial fractures varies from country to country. Population density, lifestyle, cultural background, and socioeconomic status can affect the prevalence of maxillofacial injuries. Therefore, in this study, we evaluated the epidemiology and treatment plans of maxillofacial fractures in hospitalized patients in a way that would be beneficial for better policymaking strategies. In this retrospective study, medical records of 50 patients who were operated for hospitalization and maxillofacial injury were evaluated. Age, gender, fracture types, causes, treatment plans, and post-treatment complications were recorded. Most of the patients were male (78%). Most of the cases were in the 21-30 age range. Fractures were mostly caused by falls (40%) and accidents (38%), particularly motorcycle accidents, and the most common site of involvement was the parasymphysis region of the mandible. ORIF + IMF (63%) was preferred as a treatment plan. The findings of our study supported the view that the cause and incidence of maxillofacial fractures were different in each country. In contrast to many developed countries, falls and traffic accidents are the most common cause of maxillofacial fractures
Breast Tumor Detection and Classification Based on Microwave Imaging
Authors: ORAL Emin Argun , SAHAKİAN Alan V.
Published: August 2022

Limitations caused by traditional breast cancer detection and screening techniques have encouraged researchers to investigate alternative solutions. This study examines the use of a microwave-based approach for tumor detection in breast tissue and related tumor type classification using matched-filtering. Radar-like confocal microwave imaging (CMI) method constructs the foundation of such tumor detection approach. In particular, a microwave pulse is first transmitted, then back-scattered pulses are collected. All major reflective sites in the breast tissue are detected by repeating this procedure on a microwave pulse transmission-reception grid, aligning captured signals in-time to focus on a particular region in the breast tissue and superimposing such time-shifted signals to improve signal-to-clutter level. In the observed signals, clutter is originated by the heterogeneity of the breast tissue while signal is originated by a tumor site as a function of its water content.

All calculations, in the study, were performed computationally in terms of a 3D Finite-Difference Time-Domain (FDTD) simulation models. For the antenna system, two cross-polarized resistively loaded bow-ties antennas were used in the computational model, and the tumor site was modeled using five different size and morphologies. Matched-filtering, on the other hand, was performed matching such obtained observations with that of a homogenous breast tissue, namely clutter-free model. Performance of the proposed approach was tested for two different antenna array resolutions, and it was observed that this parameter is important for successful detection and classification of a tumor-site in a realistic heterogenous breast tissue model.

Published: August 2022

Abstract
Biofilm-associated infections cause important health problems all over the world. Because of the resistance to antimicrobials and their possible side effects, researchers' attention has been focused on plant extracts and their components. The aim of this study is to evaluate the antimicrobial and antibiofilm potentials of Salvia microstegia Boiss. et Bal. mericarps. The antimicrobial activity of ethanolic extract obtained from the mericarps was evaluated using the microdilution method against seven standard bacteria and three standard yeast strains. In addition, the effect of the extract on inhibiting biofilm formation and preformed biofilm of Pseudomonas aeruginosa was determined using the crystal violet method. The used extract showed moderate to low antimicrobial activity against tested bacteria and yeasts with minimum inhibitory concentration (MIC) values ranging from 62.5 to 250 µg/mL. Moreover, the extract's potential to inhibit preformed biofilms was found to be greater compared to its potential to inhibit biofilm formation. In conclusion, the tested extract obtained from Salvia microstegia mericarps showed antibiofilm potential, however, additional studies involving different strains are needed to reveal its antimicrobial potential in a more holistic perspective.

Quantitative structure-activity relationship (QSAR) models were useful in understanding how chemical structure relates to the toxicology of chemicals. In the present study, we report quantum molecular descriptors using conductor like screening model (COs) area, the linear polarizability, first and second order hyperpolarizability for modelling the toxicology of the nitro substituent on the benzene ring. All the molecular descriptors were performed using semi-empirical PM6 approaches. The QSAR model was developed using stepwise multiple linear regression. We found that the stable QSAR modelling of toxicology benzene derivatives used second order hyper-polarizability and COs area, which satisfied the statistical measures. The second order hyperpolarizability shows the best QSAR model. We also discovered that the nitrobenzene derivative’s substitutional functional group has a significant effect on the quantum molecular descriptors, which reflect the QSAR model.

Актуальность. Изучение гидрогеохимических условий и формирования состава природных вод Томь-Усинского района Кемеровской области в условиях отсутствия добычи угля и нагрузок на водные системы важная и актуальная тема для этого региона. Полученные данные позволяют расширить представления об общих закономерностях распределения элементов в системе вода–порода в условиях угольных отложений на территории, не нарушенной интенсивной разработкой полезных ископаемых, например, добычей угля или угольного метана, характерных для Кузбасса. Это позволит в дальнейшем использовать имеющуюся информацию при различных экологических и поисковых исследованиях. Цель: изучить геохимию природных вод, провести расчеты активностей основных ионов с помощью программного комплекса HydroGeo и построить диаграммы равновесия подземных вод с водовмещающими отложениями; выделить геохимические типы природных вод и изучить их изменение в соответствии с зональностью, прослеживающейся на данной территории. Объекты: подземные воды преимущественно юрских и верхнепермских терригенно-угленосных отложений тайлуганской свиты Ерунаковской подсерии Кольчугинской серии Тутуясской площади Томь-Усинского района Кузнецкого бассейна, а также речные воды территории. Методы. Химический состав воды определялся стандартными методами в Проблемной научно-исследовательской лаборатории гидрогеохимии Томского политехнического университета. Формы миграции гумусовых кислот рассчитывались с использованием программного комплекса HydroGeo. Результаты. Авторами выполнены исследования химического состава природных вод на территории Тутуясской площади Томь-Усинского района Кузбасса. В рамках данного исследования отмечено, что имеющиеся изменения в значениях минерализации и рН присущи естественному их распределению. Источником поступления вод являются атмосферные осадки, поступающие в систему из областей питания, поэтому изученные воды инфильтрационного генезиса, прослеживается гидрогеохимическая зональность. В работе показаны результаты проведенного расчета равновесий подземных вод данной площади с карбонатными и алюмосиликатными минералами вмещающих пород. Установлено, что воды имеют равновесно-неравновесный характер: они неравновесны с первичными (эндогенными) минералами, которые они и растворяют, но в то же время равновесны с глинами и карбонатами, т. е. осаждаются из вод.

Актуальность исследования определяется необходимостью применения универсальной методики конструкторского расчета при проектировании установок глубокой утилизации тепла в системах вентиляции или отведения дымовых газов газовых котлов. Использование теплоутилизаторов значительно повышает КПД котла. Наиболее проблемной задачей является определение коэффициента теплоотдачи от парогазовой смеси к поверхности теплообмена при конденсации водяных паров, который влияет на ее площадь. Проведение экспериментальных исследований рассматриваемого процесса необходимо для совершенствования методик расчета в различных диапазонах изменения параметров парогазовой смеси. Целью настоящего исследования является получение критериального уравнения подобия для вычисления коэффициента теплоотдачи от парогазовой смеси к поверхности теплообмена при конденсации водяных паров в определенном диапазоне изменения параметров смеси. Объекты: теплообменный аппарат поверхностного типа (конденсатор), парогазовая смесь, парогенератор. Методы: энергетический баланс, конструкторский расчет теплообменного аппарата, термодинамика, теплопередача, метод подобия, метод анализа размерностей, эксперименты по теплопередаче, анализ погрешности. Результаты. Проведены экспериментальные исследования процесса теплообмена при конденсации водяных паров из газовой смеси на лабораторной установке, и выполнена обработка результатов с оценкой погрешности измерений и вычислений. На основе теории подобия получено критериальное уравнение для вычисления коэффициента теплоотдачи от паровоздушной смеси к поверхности теплообмена в определенном диапазоне изменения критериев. Отклонение вычисленных коэффициентов теплоотдачи от полученных экспериментально не превысило 13 % при разных направлениях движения потока парогазовой смеси. Критериальное уравнение может быть использовано при проектировании теплообменных аппаратов, предназначенных для утилизации теплоты.
La productividad en la industria aeroespacial en México

Published: August 2022

La productividad laboral mide la relación entre la cantidad de trabajo asociado en el proceso productivo y la producción obtenida. La hipótesis propuesta plantea una relación de consecuencia lógica existente entre las industrias con orientación exportadora y una alta productividad, siendo este el caso de la industria aeroespacial en México. Por lo tanto, se pretende hallar evidencia significativa de que esta industria, al tener una base exportadora amplia, cuenta con altos índices de productividad. El método más común para medir la productividad es aquel que relaciona la cantidad de producto obtenido con el número de horas hombre trabajadas durante un periodo determinado, relación que permite evaluar el rendimiento de una unidad productiva en un periodo determinado. Ello denota resultados preliminares de que existe una relación directa positiva entre las empresas dedicadas al sector aeroespacial y su productividad, lo que significa que esta industria tiene mayor cantidad producida por unidad de trabajo utilizado. La principal contribución de este trabajo, entonces, consiste en demostrar mediante el uso de la estadística que, efectivamente, la industria aeroespacial posee altas tasas de productividad en México.

The COVID-19 pandemic spread a multidimensional crisis of never-beforeexperienced proportions. Because of it, the situation in Brazil, which already had ascenario of great vulnerabilities and social disparities prior to the pandemic, was aggravated. The crisis and the fragility of the State's responses to the emerging demands were evidenced by the effort of the organized civil society to meet such demands. This study analyses the crisis management and co-production process during the COVID-19 pandemic in the city of Santa Maria-RS, in 2020, via the Mesa Brasil food bank program. The chosen research strategy was the case study. Data collection was carried out through documentary research, interviews and surveys with managers of participating institutions in the Mesa Brasil program. For the results, a content analysis technique was undertaken. The study allowed to conclude that crisis management, through co-participation, allows the understanding of the use of innovative and collective strategies as a means to overcome the emerging difficulties arising from crises in which social vulnerability increases. The research also explains how, in the specific context of the pandemic crisis, co-production of public services stood out for the adhesion of organizations, sharing responsibility and power in the production and delivery of public services to maintain food security and reduce food waste.
