In search of the lost tradition: towards a history of Church paintings in the 1840s — first half of the 1850s
Authors: Maslov Konstantin
Published: April 2023

The last decade of the reign of Nicholas I (1845 - 1855) was the time when the projects of renewal of church paintings in Russia appeared. Public discussion of the problems of the tradition of the Russian art started with the publication in 1845 of a brochure "On Icon-paintings" by the Ostrog bishop Anatoly, who wasn't, however, a zealous adherent to the traditional icon-paintings, his "theory" of icon-paintings tending towards neoclassicism. In difference from the Right Reverend Anatoly's approach in his brochure, the Rev'd Grigoriy Debolsky argued for the inseparable connection between the national spirit (narodnost') of the church paintings and the tradition of icon-painting in an article published in the same year. Russian Academic school did not respond to the new attitudes in society: propelled by the Emperor, this school acknowledged the tradition in symbolic terms only - in the Byzantinine golden impressions in the paintings in St Isaac's Cathedral. On the whole, the ensemble of these paintings promised to become a brilliant legacy of Bologna academism. 1848, the year of a wave of revolutions in Europe that were perceived as a direct threat to the Empire, opened a period of Nicholas's reign marked, on the other hand, by the intensification of censorship, and, on the other hand, by the two projects of renewal of national church art: those by Duke G.G. Gagarin and by I.P. Sakharov, an archaeologist. The first project, which had at its base the idea, taken from French artists, of christianising ancient art, was an attempt to adapt the Byzantine tradition to the framework of the academic artistic paradigm. Sakharov's project, on the contrary, presupposed complete rejection of this academic paradigm and going back to the icon-paintings that were not yet "spoiled" by Western influences. On the eve of the Crimean war the government made an attempt to expand the national tradition by including in it the ancient paintings from the Mount Athos, in particular, the wall-paintings by Panselinos, which, as A.N. Mouravyov claimed, "are on a par with the works by Rafael and Michelangelo in colouration and modest comportment of the figures". In the new era, marked by the Great Reform of Alexander II, the attempts at a renewal of church paintings that flourished in Nicholas's times, become, for the most part, a thing of the past.

Published: April 2023

La bicicleta ha tomado gran fuerza en todo el mundo como medio de transporte; sin embargo, aún se discute su implementación en ciudades intermedias. En la presente investigación se pretende conceptualizar una red de ciclorrutas para la ciudad de Tunja, Colombia, que es una típica ciudad intermedia. La metodología se orienta a la formulación de una red básica a partir de las características de la ciudad (vocación, movilidad, morfología y distribución espacial), así como criterios de planeación urbana. En consecuencia, se presentan la caracterización de la ciudad, el análisis de la movilidad, el concepto del trazado de la red de ciclorrutas, sus costos estimados e instrumentos de planificación y financiación. Se concluye sobre la necesidad de avanzar en la investigación que permita proyectar la red de ciclorrutas propuesta a un sistema de bicicletas compartidas en la ciudad[1].

La competitividad urbana pos covid-19. Ruta desde sus componentes: identidad e imagen
Authors: Ornes Vasquez Sandra
Published: April 2023

Las ciudades son espacios de intercambio de bienes y servicios, donde ocurren procesos de riqueza e innovación, que no siempre se dan de forma equitativa y equilibrada. Por lo tanto, se incrementa la demanda de políticas acorde con la competitividad y con la sostenibilidad ambiental y social. La competitividad urba­na debe estar sustentada en atributos y capacidades para generar valor frente a las diferentes demandas de los actores locales, con incidencia en el mejoramiento integral de su calidad de vida.
          Aun con lo anterior, ante el escenario de pandemia por el covid-19, las ciudades registraron las mayores cifras de contagio y propagación, y no estaban preparadas para asumir la amenaza sanitaria. Sus actividades comerciales, servicios y espacios públicos fueron afectados, por lo que se desdibujaron y replantearon elementos estructurantes de su competitividad, como su imagen e identidad urbana. Así pues, como una respuesta de adaptación ante la amenaza reinante, cambiaron las prioridades ciudadanas, sus condiciones de vida y sus formas de relacionarse con la urbe y de vincularse con los otros.
          La emergencia sanitaria global que a la fecha (2022) aún está en curso, obligó a atender la “nueva realidad o normalidad” a partir del rescate y replanteamiento de los atributos urbanos y el fortalecimiento de las capacidades locales. Por ello, a continuación, se plantea una investigación cualitativa y exploratoria, de tipo documental, que utiliza el análisis de contenido, con el propósito de establecer una hoja de ruta hacia una estrategia de competitividad urbana post covid-19, que redimensione los elementos de la funcionalidad urbana desde el ejercicio de la planificación local.

‘Casual Friday’
Authors: Ohta Amy Snyder
Published: April 2023

There is increasing research literature on instructional pragmatics, including work on Japanese, but little research on naturally occurring classroom innovations. This article presents a study of an instructional innovation called Casual Friday, where the professor of a university multi-section advanced-beginning (2nd year) Japanese language course designated certain lessons as spaces for graduate student teaching assistants (TAs) to involve students in using Japanese casual register. Analysis of interviews with instructional staff, student survey results, and classroom and meeting observations, shows how Casual Friday, an organizational transformation of the course, transformed activity systems (Engeström, 1987, 1999, 2003). Transformed TA roles created a pedagogical safe house (Canagarajah, 2004; Pomerantz and Bell, 2011; Pratt, 1991) on Casual Fridays by providing TAs instructional autonomy, stronger horizontal connections with students, and temporary freedom from the restraints of the course-as-usual. The re-organization thus promoted TA innovation, as they creatively used language, designed materials, taught dialect, introduced Japanese youth culture, etc. Triangulation with student surveys confirms findings of the interviews and observations, while also showing that students reported languaculture learning. Results suggest the benefits of carving out spaces within normally textbook-and-grammar-focused courses for TAs to have free rein in presenting and involving students with languaculture.
Mediation and Learner Reciprocity
Authors: Wang Zhaoyu , Zhang Jie
Published: April 2023

The Oral Proficiency Interview (OPI) is an effective tool for assessing language learners’ speaking ability. While it is commonly employed in institutional contexts, the OPI has been criticized for not granting due attention to the assistance that the tester offers to the learner. Dynamic Assessment (DA), rooted in Vygotsky’s theory of the development of human higher psychological functions, believes the use of different forms of mediation, when tailored to learners’ needs, enables learners to perform beyond their current level, thus providing insights into their emerging abilities. This study explores the use of DA within the OPI framework. Through a microgenetic analysis of the mediation-learner interactions observed in a series of mock OPI sessions conducted in Mandarin Chinese, we identified the mediation and reciprocity typological moves that are significant to learner development. The analysis showed DA’s potential for not only pinpointing areas of difficulty but also identifying the learner’s Zone of Proximal Development (ZPD) and supporting their microgenetic progress. The findings indicate that DA would add an important, yet long neglected, dimension to the OPI framework.
EN Development of energy-saving technologies and cooling systems for grain storage of small seed cultures

Published: April 2023

In the modern world, refrigeration equipment systems, in particular, continuous refrigeration chain systems, without which food safety cannot be fully ensured, are becoming more and more popular. Special interest in artificial cooling systems in the grain economy of Ukraine, which is one of the country's bud­get-generating industries. Grain is one of the most important basic human food products, for the cultivation and collection of which large resources are involved. Post-harvest processing and storage is a key link in grain production. According to the Food and Agricultural Organization of the United Nations (FAO), about 20% of harvested grains in the world spoil annually. Reduction of grain losses at all stages of harvesting, transportation, storage and processing and ensuring its preservation is determined by the technology after harvest processing. In the conditions of ever-increasing volumes of grain and high rates of harvesting, the problem of preserving the harvest, more than half of which is harvested in a wet state, is becoming increasingly acute. Freshly harvested wet seed grain is unstable in storage and requires immediate processing. Low-temperature conservation in the places of preparations allows to solve the problem of long-term and high-quality storage of grain products. Small grain varieties due to their small inherent linear size, are most prone to damage during heat drying. Combined compression-absorption water-ammonia refrigerator the machine allows you to abandon the use of mains electrical sources for 7 months of the year. Such a refrigerating machine can be made in a transport autonomous version and solve the task of air conditioning in field conditions. To adapt to field conditions, the ab­sorber is made with two-phase thermosiphons and with air heat removal to the environment

На зміну вуглецевій енергетиці, що суттєво біо- і тепло- забруднює атмосферу Землі, йде екологічно чиста воднева енергетика. Тому будь-які зусилля, спрямовані на прискорене просування водневої енергетики в практику, актуальні й виправдані. В даній роботі розглядається один з можливих варіантів використання водню у якості палива комбінованої воднево-паротурбінної установки (КВПТУ) з ізохорним процесом його окиснення в повітрі камери згоряння. В установці також використовується гідродинамічний спосіб перетворення води в насичену пару та ізохорний процес її перегріву за рахунок теплоти згоряння водню. У циклі реалізовані ізохорні процеси згоряння водню у повітрі і перегрів насиченої пари, що утворюється з води, яка дроселюється на поверхню камери згоряння водню. Це зменшує кількість теплоти, яка затрачується для досягнення максимальних заданих значень температур та тисків води і водню наприкінці відповідних процесів. Для ілюстрації можливості та ефективності пропонуємого способу перетворення теплоти згоряння водню в повітрі в роботі виконані теплові розрахунки зразкових «ідеалізованих» термодинамічних циклів двох варіантів установки: в першому варіанті паро-азотна суміш розширюється до атмосферного тиску, у другому – нижче атмосферного тиску. Гідродинамічний спосіб перетворення малої кількості води в насичену пару виключає втрати теплоти, які властиві класичному паровому котлу і необхідні для введення його в робочий режим. Крім того, виключаються втрати теплоти в навколишнє середовище як з викидними газами, так і від неповноти згоряння палива. Це забезпечує значення термічного ККД ηt такої комбінованої воднево-паротурбінної установки рівним 0,4818. При секундній витраті водню МH2 = 90 г/с, теоретична потужність NT такої установки складає 6064 кВт, а питома витрата bТ водню становить 0,05337 кг/(кВт∙год)
The Effect of Music Listening on Athletes' Anxiety, Depression, and Pain: A Mini Review
Authors: Kuan Garry
Published: April 2023

Athletes are at risk for a wide range of psychological and physical disorders due to the stressors and injuries associated with sports. Anxiety, depression, and pain are the most frequent disorders, and they can all have a severe impact on an athlete's performance and potential career. This review has shown that several studies have demonstrated that listening to music, especially motivational and relaxing music, before, during, and after sports can be an emotionally engaging distraction that can help reduce negative emotions, the feeling of pain, as well as the accompanying negative affective experience. This mini review lays the groundwork for understanding how listening to music affects athletes, making it a non-invasive and less expensive way to treat anxiety, depression, and pain caused by sports.

Published: April 2023

OBJECTIVES This study aimed to compare the functional movement screen (FMS) scores of baseball players according to their careers, for the purpose of injury prevention and healthcare programs.METHODS The study subjects were evaluated by measuring the differences in the seven fundamental movement patterns of FMS between groups according to their baseball career stages. The study included 27 college baseball players and 17 middle and high school baseball players, and analysis was conducted using STATA Version 15.0 (STATA Corp., College Station, TX, USA).RESULTS In the FMS total score, the rate of poor FMS total score (≤14) was statistically higher in 96.3% of the college baseball player than 41.18% of the middle and high school baseball player (p<0.001). In the mobility part, the rate of low FMS score (≤1) in shoulder mobility was statistically higher in 77.78% of the college baseball player than 35.29% of the middle and high school baseball player (p<0.001). In the motor control part, the rate of low FMS score (≤1) in the rotary stability was statistically higher in 62.96% of the college baseball player than 5.88% of the middle and high school baseball player (p<0.001). In the functional patterning part, the rate of low FMS score (≤1) in the in-line lunge was statistically higher in 62.96% of the college baseball player than 5.88% of the middle and high school baseball player(p<0.001). And the rate of low FMS score (≤1) in the hurdle step was statistically higher in 77.78% of the college baseball player than 41.18% of the middle and high school baseball player(p=0.014).CONCLUSIONS Our results indicate that college baseball players had lower functional movement scores compared to middle and high school baseball players. The findings confirm that additional training is necessary to improve the functional movement of college baseball players with more experience.
Acute Effects of Electromyography Biofeedback Training on the Joint Position Sense and Pain in Adults with Patellofemoral Pain
Authors: Park Jooeun , Shin Seung Woo , Kang Shin-Beum , Kim Junghoon
Published: April 2023

OBJECTIVES Electromyography (EMG) is a common technique used in clinical settings, which utilizes visual biofeedback to correct muscle activation during exercise. However, it is unclear whether the correction of muscle activation by the EMG biofeedback training restores proprioception, dynamic stability, and pain. In addition, to our knowledge, no study has investigated acute EMG biofeedback training on proprioception in adults with patellofemoral pain.METHODS The participants were twenty-nine adults (23 males and 6 females) aged ≥ 20 years with patellofemoral pain. We randomly assigned participants to either the EMG biofeedback training (EBT) group (n=15, mean age: 20.13±1.55 years) or the control group (n=14, mean age: 20.93±2.43 years). Proprioception of the knee joint was measured using joint position sense (30°, 45°, and 60°) tests. A numerical rating scale (NRS) was used to confirm the level of knee pain. The intervention group received EMG biofeedback training to increase the muscle activation of the vastus medialis oblique muscle, providing visual biofeedback using EMG.RESULTS The positional error evaluated in the 45° joint position was significantly decreased after the intervention (EBT: pre= 3.76±2.33°, post= 2.11±1.85°, P=0.020), with an interaction between time and group (P=0.028), but not other joint positions (30° and 60°). The NRS score reduced (EBT: pre= 3.87±2.20, post= 2.00±1.46, P=0.001), with a significant interaction between time and group (P=0.001).CONCLUSIONS The findings suggest that acute EMG biofeedback training reduced knee pain in adults with patellofemoral pain. The improvement of positional error was observed in the 45° joint position but not in the other joint positions. Further research is needed to evaluate whether short- and long-term biofeedback training with EMG used in the treatment of patellofemoral pain is associated with outcomes of proprioception.
How Peace Corps volunteers influence the United States: an analysis based on pragmatism
Authors: Ye Long , Liao Zhihua , Yu Yuanyuan
Published: April 2023

Abstract: From the perspective of pragmatic diplomatic philosophy, Peace Corps can benefit the United States, which is an important reason for the domestic support it receives within the United States. Through the volunteers’ acculturation experience, cultural exchanges between the United States and host countries are promoted and the awareness of the American society about the Third World countries is raised, which is the true value of the Peace Corps from the perspective of American interests. As members of American society, Peace Corps volunteers gain a comprehensive and in-depth understanding of the Third World in their host countries, which is not only an important part of improving the awareness of the American society the Third World, but is also an important bridge to spread this awareness in the United States. When volunteers return to the United States after finishing their service, they bring their understanding of the Third World to different industries and fields in American domestic society. Among them, American education and diplomacy are mostly affected. These are of great significance in improving the international vision and awareness of American education and the reliability of American foreign policy.
Mao Zedong’s thought and the construction of socialist ideology
Authors: Zhang Min , Zong Haiyong , Zeen David
Published: April 2023

Abstract: The 70-year practice of New China shows that our party has, permanently, attached importance and strengthened the leadership of ideological work, which is an essential factor for the Chinese nation to achieve the leap from standing, wealthy to powerful, and consolidate continuously the ruling position of the party. The successive leadership collectives of the party have explored and innovated the theory of socialist ideology in different periods of the history of China in light of the international and domestic situation, providing the CPC with a scientific theoretical basis and action guidelines for breaking through ideological barriers in its long-term rule. Mao Zedong made significant historical contributions to explore the road to new Chinese socialism, institutional design, theoretical innovation and ideological construction. The purpose of this study is to combine the basic principles of Marxism with the specific reality of China, creatively put forward the basic principles and basic directions of national ideology construction, and systematically elaborate the essential connotation, guiding ideology, primary objectives, fundamental nature and realization path of socialist ideology construction. This study shows that the first theoretical leap of the localization of Marxist ideology in China has laid a solid foundation to build a scientific and complete country and a scientific and complete national ideology system.
Ansai peasant paintings: inheritance of chinese primitive culture and primitive philosophy
Authors: Chang Yaqian , Zhou Liming , Lu Peng , Yasmeen Samina
Published: April 2023

Abstract: Chinese primitive philosophy, as the unity of cosmological ontology, epistemology and methodology of the Chinese philosophical system, is a complete and mature philosophical system formed in the late primitive society as early as before the Xia, Shang and Zhou Dynasties. It is also the unity of the concept of Yin and Yang and constant life that is sublimated from the human-beings’ basic cultural consciousness: life consciousness and reproduction consciousness. The Chinese primitive culture, from the painted pottery culture 7,000 years ago to today, from the underground archaeological culture to the group culture on the ground, is a plastic art based on the concept of viewing objects and taking images. It is a broad concept of fine arts that determines the philosophical view, artistic view, emotional temperament, psychological quality and national spirit of the Chinese nation. The most primitive culture and primitive philosophy in China have been preserved with extremely rich and complete historical remains in the group’s cultural and social life. It is for this reason that China is the only country with an ancient history of civilization that has not experienced a cultural break. The primitive culture and philosophical system of China, as the philosophical basis and main connotation of ethnic group culture, are completely accumulated in the ethnic groups’ social life. Folk art, which has accumulated the hundreds of millions of working masses’ wisdom in China, is the mother of the Chinese national culture and art that has been inherited from primitive society until today with distinct national and regional characteristics. It is a long-standing cultural form with the longest history, the widest mass participation, the most distinct regional characteristics and the richest cultural connotation in the Chinese national cultural form. The rapid development of the times makes the traditional folk customs and folk arts, which are generally deposited in the rural areas of China, become precarious. As a result, the research advantages of the unique human culture and the original culture of China will cease to exist. Therefore, it is an urgent historical task to make use of this advantage to study the original culture of China and the philosophical genes of the Chinese nation. Protection is imminent, and inheritance is the historical mission, which highlights the deeper significance of studying primitive culture and primitive philosophy in modern society.

Published: April 2023

ABSTRACT: This study evaluated the effects of Acacia mearnsii tannin extract on milk fatty acid profile of dairy ewes and cows. In experiment 1, twenty-four Lacaune ewes received one of the following dietary treatments: control (no tannin extract added to the diet), T30 (30 g tannin extract/kg concentrate), and T40 (40 g extract/kg concentrate). In experiment 2, thirty Jersey cows received either a control diet (no tannin extract added to the diet) or the same diet containing 40 g tannin extract/kg concentrate (T40). Dry matter intake, milk production and milk solids content of ewes and cows were unaffected by tannin supplementation. The cis-9, trans-11 conjugated linoleic acid (CLA) content increased linearly by 21% in milk fat from ewes fed tannin extract, while the C18:2 n-6 (linoleic acid) content tended (P = 0.051) to increase by 13% in cows fed TE. The supplementation with black wattle tannin extract improves the nutritional quality of milk fat of ewes and cows to a small extent, with no adverse effects on performance or gross milk composition.
Population suppression of phylloxera gallicolae and radicicolae forms on grapevines with the use of synthetic insecticides
Authors: Andzeiewski Simone , Oliveira Daiana da Costa , Bernardi Daniel , Botton Marcos
Published: April 2023

ABSTRACT: The grapevine phylloxera Daktulosphaira vitifoliae (Fitch, 1856) is the main insect pest of viticulture globally. Infestations can occur in the aerial part of the plant (gallicolae form) and roots (radicicolae form). In this study, the effect of insecticides on the populations suppression of the gall and root forms of phylloxera one vine was evaluated. For the gallicolous form, the thiamethoxam (Actara 250 WG®, 40g c.p./100L-1), flupyradifurone (Sivanto® Prime 200 SL, 75mL c.p./100L-1), and sulfoxaflor (Closer® SC, 40mL c.p./100L-1) were evaluated in the field, under natural infestation, using rootstock plants ‘Paulsen 1103’ (Vitis berlandieri x V. rupestris). For the root stage, an experiment was carried out in a greenhouse using rooted seedlings of ‘Cabernet Sauvignon’ (Vitis vinifera) grown in pots artificially infested with 200 phylloxera eggs per plant. After 80 days of infestation, the thiamethoxam (0.2g p.c./plant), flupyradifurone (0.8mL p.c./plant), sulfoxaflor (0.3mL/plant) and imidacloprid (Proved 200 SC, 0.7 mL/plant) were applied via drench. For the gallicolae form, an application of the flupyradifurone provided a gall reduction of 90% at 28 days after the first application (DAFA). While for thiamethoxam, 3 applications were needed at weekly intervals to maintain the same level of control. For sulfoxaflor, a second application at 14 DAFA was necessary to provide a level of control above 90%. For the root stage, the insecticides sulfoxaflor and imidacloprid showed the best results, with 96 and 89% of control over nymphs and adults, respectively. The insecticides flupiradifurone and sulfoxaflor are suitable for the chemical control of phylloxera in the vine.
Production and economic evaluation of the Corriedale, Highlander and Milchschaf sheep breeds in Southern Uruguay
Authors: Bell Washington , Sánchez Ana Laura , Ponzoni Raúl
Published: April 2023

ABSTRACT: Sheep production is expanding among small farmers in Southern Uruguay. Currently, Corriedale and Milchschaf are being used, but not Highlander. However, there is lack of experimental information regarding the relative performance of these breeds. We conducted an experiment where these three sheep breeds were run together at the Southern Regional Centre, located in the region in question. Wool, body, reproductive and lamb growth traits were recorded from 2015 to 2019. Results were used as a basis for the calculation of gross margins for each breed, which we calculated for a range of production and economic scenarios. For scenarios based on the results of the present study Highlander was the best performing breed. If it was assumed to be wool-less, it performed even better. In some scenarios Corriedale performed best, especially when the higher wool price it used to enjoy was assumed. However, fetching such a price in the foreseeable future is unlikely. We concluded that in the absence of wool-less sheep that perform in a manner similar to Highlander or Milchschaf in terms of reproduction and lamb growth, Highlander is currently the best option for small farmers in Southern Uruguay. Until now, Milchschaf has been the recommended breed for the region and production system in question. The recommendation should be reviewed, Highlander should be recommended instead, and the performance of wool-less breeds should be investigated. Results could be applicable to other temperate regions in Latin America where similar production systems exist or may be developed.

Published: April 2023

Abstract Detrusor hypocontractility (DH) is a disease without a gold standard treatment in traditional medicine. Therefore, there is a need to develop innovative therapies. The present report presents the case of a patient with DH who was transplanted with 2 x 106 adipose tissue-derived mesenchymal stem cells twice and achieved significant improvements in their quality of life. The results showed that cell therapy reduced the voiding residue from 1,800 mL to 800 mL, the maximum cystometric capacity from 800 to 550 mL, and bladder compliance from 77 to 36.6 mL/cmH2O. Cell therapy also increased the maximum flow from 3 to 11 mL/s, the detrusor pressure from 08 to 35 cmH2O, the urine volume from 267 to 524 mL and the bladder contractility index (BCI) value from 23 to 90. The International Continence on Incontinence Questionnaire - Short Form score decreased from 17 to 8. Given the above, it is inferred that the transplantation of adipose tissue-derived mesenchymal stem cells is an innovative and efficient therapeutic strategy for DH treatment and improves the quality of life of patients affected by this disease.
Inquérito policial como tática de vigilância: novas tecnologias e a criminalização dos protestos de 2013
Authors: Fernandes Eduardo Georjão
Published: April 2023

Resumo O artigo busca analisar os usos de novas tecnologias da comunicação e da informação (TICs) em inquéritos contra ativistas a partir de pesquisa sobre a criminalização de manifestantes no ciclo de protestos de 2013 em Porto Alegre. Por meio da análise de conteúdo do inquérito contra integrantes do Bloco de Lutas pelo Transporte Público, complementada por entrevistas com policiais civis, a pesquisa identifica que a narrativa policial se fundamenta em uma lógica inquisitorial, que classifica os indiciados como “lideranças” predispostas ao cometimento de delitos e vinculadas à simbologia anarquista. Do conjunto de táticas adotadas pelas forças policiais no inquérito (infiltração em eventos de protesto; estigmatização de manifestantes; coleta de depoimentos; uso de imagens; buscas e apreensões; monitoramento das redes), as TICs são operacionalizadas centralmente nas três últimas para reforçar a narrativa construída pelas fontes de informação tradicionais, tendo como principais efeitos a amplificação da visibilidade sobre os manifestantes e a busca por legitimação policial. O inquérito é centralmente mobilizado para coleta massiva de informações sobre os ativistas, constituindo-se como tática de vigilância.

Authors: Queiroz Letícia Lopes de , Silva Leonardo Gomes de Oliveira da , Pinheiro Hudson Azevedo
Published: April 2023

ABSTRACT This study analyzed the timed up and go test (TUG) as a tool to evaluate muscle strength in community-dwelling older people. As a methodology, an observational, cross-sectional and analytical study was conducted. Data from 442 older people were analyzed, both women (71.7%) and men (28.3%). Ages ranged from 62- 104 years, with a mean of 80.85 (±8.047) years. TUG was used as a tool to evaluate muscle strength. Comparison and correlation analyses were performed to compare performance between the TUG and the chair stand test (CST) and between TUG and handgrip strength (HGS). Analysis of agreement between the diagnosis of low physical performance on TUG and the diagnosis of muscle weakness on CST and HGS was also performed. The predictive values were estimated using the receiver operating characteristic curve. The analyses showed a moderate direct proportional correlation between TUG and CST performance and low inversely proportional correlations between TUG and HGS performance and between CST and HGS (p<0.001). In the accuracy analyses, it was observed that TUG test could predict muscle strength in CST (S 34.4%; PPV 91.5%; NPV 26.1%; AUC=0.779; 95%CI 0.724-0.835; p<0.001) and handgrip dynamometry (S 44.2%; PPV 77.4%; NPV 67.2%; AUC=0.652; 95%CI 0.599-0.705; p<0.001). The Timed Up and Go test was able to satisfactorily indicate individuals with normal muscle strength in CST.

ABSTRACT Patellofemoral pain (PFP) may contribute to less activation of the quadriceps muscle, favoring joint overload and pain. Neuromuscular efficiency (NME) is a variable that evaluates the relationship between the amount of neural stimuli and the ability to generate force of in a given muscle, with the most efficient being the one that produces greater muscle force, with less activation of muscle fibers. In this sense, this study aimed to evaluate the strength and NME of knee extensors in women with and without patellofemoral pain. A total of 24 adult women, recruited via a questionnaire, aged from 18 to 30 years, with and without patellofemoral pain, participated in this study. Anamnesis, anterior knee pain scale, and numerical visual scale were applied. Subsequently, the knee extensor strength, with a hand-held dynamometer, and the NME of vastus medialis (VM), vastus lateralis (VL), and rectus femoris (RF) were assessed. For statistical analysis, appropriate tests were adopted to compare variables between groups and correlate them. In all statistical tests, a α<0.05 was adopted. Results showed that women with PFP had 61% lower NME in the VM and 52% in the VL, compared to the group without pain. No significant difference was found for knee extensor strength between groups. We conclude that pain negatively influences VM and VL recruitment but does not change quadriceps ability to generate strength.

ABSTRACT Traditional ecological knowledge of indigenous groups in the southeastern Colombian Amazon coincides in identifying the two main hydrological transition periods (wet-dry: August-November; dry-wet: March-April) as those with greater susceptibility to disease in humans. Here we analyze the association between indigenous knowledge about these two periods and the incidence of two vector-borne diseases: malaria and dengue. We researched seven “ecological calendars” from three regions in the Colombian Amazon, malaria and dengue cases reported from 2007 to 2019 by the Colombian National Institute of Health, and daily temperature and precipitation data from eight meteorological stations in the region from 1990-2019 (a climatological normal). Malaria and dengue follow a seasonal pattern: malaria has a peak from August to November, corresponding with the wet-dry transition (the “season of the worms” in the indigenous calendars), and dengue has a peak in March and April, coinciding with the dry-wet transition. Previous studies have shown a positive correlation between rainfall and dengue and a negative correlation between rainfall and malaria. However, as the indigenous ecological knowledge codified in the calendars suggests, disease prediction cannot be reduced to a linear correlation with a single environmental variable. Our data show that two major aspects of the indigenous calendars (the time of friaje as a critical marker of the year and the hydrological transition periods as periods of greater susceptibility to diseases) are supported by meteorological data and by the available information about the incidence of malaria and dengue.

ABSTRACT Studies regarding deforestation, the hydrological cycle, climate change and fire weather can benefit from the detailed simulations provided by regional climate models (RCM). While much attention has been given to fire activity in the Amazon, few studies have used RCM runs to assess fire risk and variables associated to fire occurrence. We evaluated precipitation, temperature and a fire risk index from the ensemble of Eta model simulations coupled with three different global climate models for the Amazon basin. The RCM runs were compared to reanalysis data for the dry season from 1979 to 2005. The maximum and 2-m temperature fields were underestimated over the entire region, but showed a statistically significant spatial correlation with the reference data. Precipitation was overestimated over the Amazon, in accordance with the major sources of moisture analyzed. The Keetch-Byram drought index (KBDI) was not significantly affected by the bias found in temperature and precipitation, and the ensemble improved relative to the individual member simulations. KBDI estimations performed better with the ensemble of the three evaluated members, however the Eta model showed some limitations. The validation of modeled fire risk could benefit from the use of satellite hotspot data. Furthermore, the KBDI can also be used in the assessment of how climate change interacts with fire activity in the Amazon region.
Ecomorphology and functional diversity of generalist and specialist bird assemblages in Amazonian white-sand ecosystem habitat patches

ABSTRACT Birds that inhabit white-sand ecosystems (WSE) in the Amazon are adapted to habitats distributed as isolated patches. These environments occur in sandy soils that are extremely poor in nutrients, have low floristic diversity and support bird assemblages restricted to WSE. We investigated whether bird species specialized in WSE have morphological or ecological traits that distinguish them from generalist birds that share the same habitat but are not restricted to WSE. We collected morphological and ecological data from 22 specialist and 102 generalist bird species from WSE and described their ecomorphological diversity using multivariate analyses and measures of functional diversity. Understory insectivorous species that move alone or in pairs, were the group with the most species among specialist birds from WSE. In contrast, canopy frugivorous species that form mono- or heterospecific groups were more frequent among generalist species. Specialist and generalist birds overlapped extensively in ecomorphological space, with specialists occupying a narrower space compared to generalists. Functional diversity, however, was not different between specialist and generalist species when controlling for the number of species within the communities. Further studies comparing the ecomorphological diversity of bird assemblages of other environments in the Amazon may highlight the ecological pressures leading to the functional diversity of specialist species in WSE observed in this study.

Abstract The objective was to systematically search and synthesize the evidence available in the literature about the effect of physical exercise interventions Primary Health Care (PHC), carried out in Brazil, on cardiometabolic risk factors. The search was performed in the PubMed, Virtual Health Library and Web of Science databases. The inclusion criteria were: studies with physical activity (PA) interventions or exercise in PHC; carried out in Brazil; population aged >18 years; at least one cardiometabolic risk factor assessed pre and post-intervention. The “Health Sciences Descriptors” were used to define the search descriptors: “physical activity” OR “exercise” OR “motor activity” AND “primary health care” OR “health centers” OR “primary care” AND “Brazil”. The selection phases were performed by pairs of blinded researchers and the conflicts were decided by a third evaluator. Jadad scale was used to assess the methodological quality of the articles included. In total, 1,817 articles were found and 26 duplicates excluded, leaving 1,791 for reading of titles. The abstracts of 105 articles were read, and 53 articles were read in full. Finally, 06 articles were considered eligible and included in the review. The cardiometabolic risk factors evaluated in the included studies were body mass index (4 studies), waist-hip ratio (1 study), fat percentage (1 study), blood pressure (2 studies), lipid profile (1 study), inflammatory profile (1 study), and aerobic capacity (3 studies). It is concluded that there is insufficient evidence in the literature about the effect of exercise interventions in PHC with a focus on cardiometabolic risk factors.

Abstract Basketball is a sport practiced around the world in this way, performances tests especially with low-cost and accessible are suggested to adjust the training. The 00aim of present study was to evaluate and correlate the speed and jump performance of lower limbs of basketball athletes from the Praia Grande, city of São Paulo, Brazil. Twelve male athletes (6.92 ± 2.57 years of pratice) from the Basketball team of Praia Grande City, aged 18.7 ± 0.6 years, height 1.85 ± 0.06, body mass 83.66 ± 10.16 kg were evaluated. The athletes were submitted to test sessions using the protocol for evaluating the maximum speed of 20 meters and the unilateral vertical jump. The speed on 20 meter test was 3.53 ± 0.20 seconds. Although an asymmetry of 17.81 ± 14.64% was found, no statistical difference (p = 0.817) was found between the dominant (36.50 ± 7.36 cm) and non-dominant (35.92 ± 5.63 cm) of vertical jump performance. Additionally, correlation between 20-meter test and values jump was found to dominant leg (p = 0.042) but not to non-dominant leg (p = 0.704). In conclusion, although asymmetry was found between members of the dominant and non-dominant side of the pitch, did not show any difference in the vertical jump.

Abstract Competition is the essence of sports and, when conceived having participants as references, it can contributes to the development of different pedagogical contents, among them, socio-educative aspects and autonomy. The purpose of this research was to demonstrate the first validity evidences of two scales for supporting socio-educational and autonomy development in youth sports; both are part of the Battery of Tests Gonçalves-Balbinotti of Pedagogical Contents’ Development Support in Youth Sports. We aim to estimate their internal structures, test their stabilities and estimate their internal consistency. A sample of 210 coaches answered the scales related to socio-educational and autonomy development, which presented second order two-factor structures with significant factor loadings (> 0.40) and explaining 80.6% and 73.2% of the constructs’ total variance, respectively. The results related to the model fit were satisfactory (X2/df < 2.00; AGFI > 0.95; RMSEA < 0.05; CFI > 0.95; TLI > 0.95). The results regarding the internal consistency (0.786 < α < 0.913 for the factors; αSE = 0.889; αAu = 0.870) assure the precision of the measures and the reliability of their uses according to their purposes. The results answer the main and specific purposes of this research and indicate the safe use of these two scales.
