Published: December 2020

COVID-19 pandemic in Indonesia has an impact on learning process, which requires students to learn bynetwork/long distance. One of the platforms that teachers can used is Microsoft Teams. To be able to improvethe ability of students in solving problems in mathematics learning, teachers must make learning situationswith more problems solving, so students can more active in solving problems related to this material. Thelearning model that teachers can use is Guided Discovery Learning. Based on the findings in class, one of themathematics topics in SMK that are still difficult for students to understand is matrix. This is because matrixis considered an abstract material and is not related to everyday life. Students bored in studying matrixbecause this material consists of many numbers and requires high accuracy. So it takes learning media thatcan attract and help students in learning these materials. One of the learning media that can be applied isExcel Matrix. This research was conducted on 34 students of XI APAT 2 in SMK Negeri 1 Grati. Thisresearch is a classroom action research (PTK) which consists of 3 cycles. The results showed that in cycles 1and 2 it was still said to be not good, meaning that students were not yet able to understand problems, plansolutions, carry out solutions, and re-check solutions, while in cycle 3, the ability to solve mathematicalproblems of students could be said to be good according to the success criteria. which is determined as many as 23 students from the total (68%) in good or very good criteria in solving problems.

Published: December 2020

A cana-de-açúcar é um dos principais produtos agrícolas do Brasil, gerando alimento e energia sustentável para o mundo. No estado de Goiás, o déficit hídrico é um dos fatores limitantes do acúmulo de biomassa, devido à baixa umidade do solo durante praticamente todo o outono e o inverno. Objetivou-se com este trabalho avaliar os efeitos de lâminas de irrigação de salvamento no desenvolvimento inicial da cana-soca de sequeiro, durante os primeiros 30 dias. O experimento foi realizado na Fazenda Isaura, pertencente à Usina São Martinho - Unidade Boa Vista, no município de Quirinópolis, GO. A colheita foi finalizada em 18 de setembro de 2019 e a irrigação ocorreu com Lead Time (dias após colheita) de 7 dias, no dia 25 de setembro de 2019. Utilizou-se o delineamento de blocos casualizados arranjado em faixas. Foram utilizadas cinco lâminas de irrigação (20 mm, 30 mm, 40 mm, 50 mm e 60 mm), uma testemunha (sem irrigação) e seis repetições. Foram avaliados os parâmetros biofísicos: número de perfilhos por metro linear, altura das plantas e massa fresca dos perfilhos. O número de perfilhos por metro linear, altura das plantas e massa fresca dos perfilhos responderam ao aumento das lâminas de irrigação, em todos os períodos avaliados após o plantio, sendo o modelo de regressão linear o de melhor ajuste. Desde que não supere a capacidade de armazenamento de água no solo, o aumento da lâmina de água proporciona aumento do perfilhamento, altura média das plantas e massa fresca dos perfilhos da cana-soca. A lâmina de irrigação de salvamento de 60 mm foi a quantidade ótima para potencializar o perfilhamento da cana-soca.

Muitos produtores resistem em adotar a presença dos animais nas lavouras, pois acreditam que possa compactar o solo e causar redução na produtividade da cultura em sucessão. Diante disso, objetivou-se avaliar os atributos químicos e físicos do solo após o cultivo de forrageiras invernais sob manejos de pastejo e soja em sucessão em sistema de integração lavoura-pecuária. O experimento foi conduzido em um LATOSSOLO VERMELHO sob o delineamento de blocos ao acaso, em esquema de faixas, com três repetições. Foram testados diferentes forrageiras invernais (aveia BRS 139, aveia preta IPR 61, aveia branca IPR Esmeralda, Triticale 111 Tpolo e o consórcio de Triticale 111 TPolo e aveia IPR Esmeralda), manejos de pastejo (sem pastejo, um pastejo e dois pastejos) e profundidades do solo (0-0,05, 0,05-0,10 e 0,10-0,20 m). Foram determinados os seguintes atributos: nitrogênio total (NT), carbono orgânico total (COT), relação carbono e nitrogênio (C/N), matéria orgânica do solo (MOS), porosidade total (Pt), macroporosidade (Mac), microporosidade (Mic) e densidade aparente (Ds). As forrageiras utilizadas para pastejo no período de inverno resultaram em diferentes teores de MOS, NT e Mac. O cultivo do Triticale 111 TPolo resultou em menor Mic e Pt quando manejado sob dois pastejos nas camadas de 0,05-0,10 e 0,10-0,20 m e a maior Ds foi encontrada na camada superficial, independentemente da forrageira e manejo. As forrageiras invernais quando submetidas a pressões de pastejo não modificaram os atributos do solo entre as profundidades avaliadas.

Published: December 2020

A curva glicêmica e a taxa de excreção de amônia são métodos utilizados para avaliar a variação da glicose e da excreção do composto nitrogenado amônia em função de alterações na quantidade de carboidratos e proteínas, respectivamente, disponíveis nas rações. No entanto, os relatos são escassos quanto a sua utilização em pesquisas relacionadas ao uso de enzimas exógenas na alimentação de peixes. Mediante o exposto, o objetivo do trabalho foi de avaliar os níveis de glicose sanguínea e a taxa de excreção de amônia como indicadores metabólitos da eficiência da atividade de enzimas exógenas em dietas para tilápias do Nilo. Desta forma, foram realizados dois experimentos onde foram testadas a composição e concentração das enzimas fitase, alfa-amilase e protease. Os tratamentos foram compostos por dieta controle (DC), que posteriormente, foi suplementada com um blend 1 contendo 100ppm fitase + 200ppm protease, um blend 2 composto por 100ppm fitase + 400ppm protease, depois o blend 3 contendo 200ppm fitase + 200ppm protease + 133ppm alfa-amilase, e o blend 4 com 200ppm fitase + 400ppm protease + 200ppm alfa-amilase. O pico da glicemia sanguínea das tilápias do Nilo ocorreu nas primeiras 4 horas pós alimentação das tilápias em todos os tratamentos avaliados. As dietas suplementadas com fitase, protease e alfa-amilase promoveram maiores níveis de glicose sanguínea, enquanto, os picos de excreção de amônia ocorreram às 2h, 4h e 8h pós alimentação, o que pode estar relacionado ao aumento da disponibilidade de proteína pela suplementação das dietas com a protease. As concentrações de glicose sanguínea e a taxa de excreção de amônia podem ser indicadores indiretos da eficiência da atividade de enzimas digestivas em tilápias do Nilo.

Published: December 2020

A deficiência do micronutriente boro (B) se destaca pelos prejuízos relativos à formação e qualidade da colheita, sendo importante a compreensão de seu manejo e de sua aplicação no cultivo de grãos. O objetivo do estudo foi avaliar o crescimento e o rendimento da cultura de trigo em resposta a doses e formas de aplicação de boro. O estudo foi conduzido em casa de vegetação, em Cascavel, Paraná, Brasil. O delineamento experimental foi o de blocos casualizados, e os quatro tratamentos avaliados foram: testemunha sem adição de B; fertilização via sulco (octaborato de sódio 20,5% de B, 1,0 kg.ha-1); fertilização via foliar (octaborato de sódio 2% de B, 150 mL.ha-1) e fertilização via sulco mais foliar (1,0 kg.ha-1 de octaborato de sódio 20,5% de B + foliar 150 mL.ha-1 de octaborato de sódio 2% de B). Foram avaliados o comprimento do sistema radicular e da parte aérea, bem como massa seca da planta e rendimento de grãos. A fertilização com B via sulco e foliar proporcionou incremento de 56,5% no rendimento de grãos em relação às plantas que não receberam esse micronutriente. A aplicação de B favoreceu o crescimento e rendimento do trigo, sendo recomendada sua aplicação via sulco e via foliar na adubação da cultura.

Published: December 2020

A partir do estudo de caso da Comarca de Bragança, no Pará, este artigo analisa o processo de organização e preservação documental, pelo qual passa o acervo histórico dessa unidade judiciária estadual. Desde 2017 com a assinatura do convênio de cooperação entre o Tribunal de Justiça do Pará (TJPA) e a Universidade Federal do Pará (UFPA), atividades de conservação preventiva são realizadas junto ao setor de arquivo do Fórum de Bragança, onde cerca de cem mil registros de natureza cível, criminal e administrativa, datados de meados do século XIX até os dias atuais, encontravam-se acumulados em condições inapropriadas. Com mais de três anos de vigência, o convênio resultou, dentre outras coisas, em um projeto de extensão vinculado a Faculdade de História, do campus de Bragança, que coordena o tratamento da documentação de valor permanente e através do qual a memória institucional e social do Poder Judiciário paraense vem sendo recuperada em função das pesquisas de caráter histórico, produzidas a partir de então, que têm nessa documentação sua principal fonte de informação.

PRESENÇA NEGRA NO ESTADO DO AMAZONAS: a contribuição dos arquivos do TJAM
Authors: Silva Junior Juarez Clementino da
Published: December 2020

A presença negra na Amazônia e notadamente no Amazonas tem uma histórica negação ou minoração. Parte por ter pertencido a outra colônia  portuguesa nas Américas, o Grão Pará e Maranhão, integrado ao estado do Brasil após a independência desse último e que pelas características da região teve exploração econômica diferente em relação a outras regiões, com uso bem mais modesto de mão de obra escravizada negroafricana. Na segunda metade do século XIX havia uma não reduzida parcela de negros livres e libertos na população, além de um parcela menor de ainda escravizados. Outra parte da negação, vem da modernização trazida pelo fausto da borracha, a cidade de Manaus aspirava ser uma “Paris dos Trópicos”, essa aspiração cosmopolita da “Belle Epoque” se alinhava a outra, higienista, em que as figuras do negro e do indígena deveriam ser se não fisicamente eliminadas, ao menos ocultadas. O que acabou se tornando crença popular de não presença negra até muito recentemente. Nos últimos anos a academia se voltou à desconstrução dessa negação, através de várias pesquisas de pós-graduação, sobretudo em História. Parte das pesquisas tem utilizado o acervo histórico do arquivo do Tribunal de Justiça do Amazonas. Aliás o acervo foi premiado em 2018 com o selo “Memórias do mundo” da UNESCO, pelo conjunto documental “Africanos livres na Justiça amazonense do Séc. XIX”, sendo o primeiro e único acervo do estado a possuir tal distinção.
“FÊ-LO NO IMPULSO DE UM NOBRE CRIME, SENÃO DE SENTIMENTO DA HONRA ULTRAJADA”: a violência contra a mulher nos autos crimes de ferimentos leves da comarca de Bragança-PA (1910-1920)
Authors: Miranda Filipe De Sousa
Published: December 2020

A Comarca de Bragança-PA, instituída no ano de 1839, configura-se uma das mais antigas e dinâmicas do atual Estado do Pará. Ao longo de seus, aproximadamente, 180 anos de funcionamento, esta acumulou em seu Acervo Permanente ou Arquivo Histórico um vasto quantitativo documental, que configura-se instrumento imprescindível, para a compreensão da história do judiciário paraense, de seus servidores, magistrados e jurisdicionados em diferentes contextos históricos. Dentre estes registros estão os Autos Crimes de Ferimentos Leves datados da segunda década do século XX. O presente trabalho, voltando-se para estes processos criminais, que de acordo com a estrutura organizacional vigente, eram de competência do Tribunal Correcional,  objetiva analisar os mecanimos, a partir dos quais, se produz ao longo do trâmite processual, uma “verdade” final, acerca do fato que originou a denúncia. Com esse intuito recorre-se as  narrativas atribuídas aos diversos sujeitos que emergem nos Autos, tanto aqueles incubidos de movimentar as engrenagens disciplinadoras da justiça pública (juízes, delegados, escrivães, oficiais, dentre outros), quanto aqueles que recorreram a instituição, como estratégia para a resolução de suas demandas, ou diante dela foram compulsoriamente levados para prestar esclarecimentos. Compreende-se que o processo de construção desta “verdade” que será ser levada em conta no ato de elaboração da sentença,  legitima discursos que, por sua vez,  apresentam vestígios de práticas, valores e estruturas que caracterizavam a sociedade bragantina neste contexto. Demonstrando-se, deste modo, o quanto o poder judiciário, enquanto instituição normativa dinâmica, está intimamente imbricado a vida em sociedade.
OS PARADIGMAS DA ESTRUTURA CURRICULAR DAS PRIMEIRAS FACULDADES DE DIREITO NO BRASIL
Authors: Moreira Bretas Carlos Renan , Nunes Costa Maria Alice
Published: December 2020

Este artigo analisa o surgimento das primeiras faculdades de Direito no Brasil, em 1827, em Olinda e São Paulo. Os novos cursos pouco significaram em termos de produção científica na primeira metade do século XIX, sendo observado, apenas na segunda metade daquele século, um aumento de sua expressividade acadêmica, sobretudo em Pernambuco, com a transferência da faculdade de Olinda para Recife, em 1854. Influenciadas por paradigmas liberais, o objetivo das faculdades era formar um corpo qualificado para atender aos interesses administrativos do Estado que se desenvolvia após a Independência. Se por um lado, em Recife, havia a preponderância de pressupostos influenciados pelo evolucionismo, cientificismo e culturalismo – sobretudo em razão de Tobias Barreto – por outro lado, em São Paulo, preponderava o pragmatismo e o ensino do Direito Civil, atendendo às necessidades das elites oligárquicas no que diz respeito a direitos contratuais e de propriedade. Ainda na segunda metade do século XIX, algumas reformas foram implementadas nos currículos acadêmicos. Nesse período, ainda, a Igreja perdeu influência na educação e no Estado e passou a não mais ter o poder de intervir no ensino, tornando-se esse “livre”.

Published: December 2020

This research aimed to produce models of hitting practice tools, which could be used
in training beginner woodball athletes in Indonesia. A process of research and
development was followed after the model of Gall, Gall, XXABSTRACT Borg (2007). Small-scale
field trials were first conducted at Gerokgak Woodball Club (GWC), or Gerokgak
Woodball Club (GWC) Buleleng-Bali, involving 10 athletes (5 males and 5 females).
These were followed by large-scale field trials conducted in Pengkab Woodball
Buleleng, or Pengkab Woodball Buleleng-Bali, involving 20 athletes (10 males and 10
females). Data gathered were both quantitative and qualitative. Quantitative
descriptive analysis was employed with the (a) observation instruments/observations of
the effectiveness of the tool development model; and (b) the athlete response
questionnaire as part of the validation process. Qualitative descriptive analysis was
applied to data gained from interviews, observations and fieldnotes in processing
suggestions for improvement from material experts, media experts, and practitioners.
This research produced an effective and appropriate hitting practice tool for beginners
in woodball and a guide/instruction on how to use the tool. These wood practice
products can be carried or moved in accordance with training needs (portable), can be
used to train the consistency of the punch, increase the frequency of hitting exercises,
in the open field (outdoor) or in the building (indoor). The wood practice tool can be
used by athletes to practice short stroke, medium, long, or finishing/gating.

Authors: Tereshina N. S. , Lyakina M. N. , Naumova O. A.
Published: December 2020

Sea water and sea salt obtained from it are widely used as substances in the production of medicinal products. Complex chemical composition of sea water which contains various salts, calls for the development of a common quality standard for sea water-based medicines. The aim of the study was to analyse and summarise available data on the sources of sea water-based medicines, and on the current test methods, as well as to develop a unified approach to quality control. The paper summarises information on the use of sea water for medical purposes. It presents comparative data on the chemical composition of sea water obtained from different sources, manufacturing technologies of sea water-based medicines, and composition of medicines produced from sea water or sea salt. The paper summarises data on the use of sea water for the production of various dosage forms: drops, sprays, aerosols. The study revealed qualitative and quantitative differences in the content of major cations and anions in drug products. The authors analysed the use of various chemical and physico-chemical test methods for qualitative and quantitative characterisation of medicines. It was concluded that there is a need to harmonise quality control methods for sea water-based medicines.
Risk-Based Approach to the Assessment of Sanitary Safety of Vivariums and Breeding Facilities, and Health Status of Personnel and Laboratory Animals
Authors: Bondareva E. D. , Borovkova K. E. , Makarova M. N.
Published: December 2020

The paper discusses the system of managing risks arising during preclinical studies (risks for the health of personnel and laboratory animals, as well as risks associated with sanitation of premises) as a way to improve and control the efficiency of processes and the safety of facilities involved in preclinical studies.

The aim of the studywas to analyse the risk assessment system’s efficiency for improvement of drug safety assessment during preclinical studies in the context of animal care and use programmes.

Materials and methods: the Failure Mode Effect Analysis (FMEA) method was used to assess the sanitary and hygienic conditions in laboratory animal facilities, as well as health status and welfare of laboratory animals and the attending personnel. The study checked the presence of pathogenic and opportunistic microflora as the main potential inconsistencies.

Results: the risk assessment performed during monitoring of laboratory animal health, monitoring of surface cleanliness, and assessment of personnel health, helped to establish a list of the most dangerous pathogens that require stricter control. In order to reduce risks arising during preclinical studies, the following set of measures was proposed: monitoring of the living environment and health of laboratory animals, revision of therapeutic and preventive measures for laboratory animals (including adjustment of antibiotic treatment depending on antimicrobial resistance of microorganisms), monitoring of the personnel health status, taking measures to enhance the personnel vigilance with respect to their own health, prohibition to work at the premises for employees showing symptoms, control of how the employees showing symptoms observe the prohibition to work at the premises, organisation of periodic medical examinations for personnel having contact with laboratory animals.

Conclusions: the risk-based assessment helped to identify the most dangerous potential inconsistencies (pathogenic and opportunistic microflora) and the necessary preventive measures to control and manage potential risk consequences.
The prospects for using haploinducers in maize breeding
Authors: Asadova G. M. , Ulyanov A. V. , Karlov M. V. , Khatefov E. B.
Published: December 2020

The discovery of spontaneous haploid plants and the development of ways to produce them inin vitroculture have set a new direction important for breeding and for theoretical research in reproductive biology. The frequency of spontaneous haploidy in cultivated plants is extremely low and does not exceed 0.01-0.1%, therefore, the search for sources and donors capable of stimulating haploidy in hybrid combinations is of current interest. Expansion of the search for new sources and donors of the haploinduction trait, the creation of new, more effective haploinducers contribute to the accumulation of scientific information and genetic sources, characterized by a high resource potential for selection and genetic research. The causеs of haploidy are not well understood yet. According to the available information, the genes localized in theqhir1,qhir11,qhir12regions of chromosome 1 in maize are responsible for this process. The use of genes that stimulate haploinduction in maize in combination with the marker geneR1-njresponsible for anthocyanin coloration of the caryopsis and embryo, as well as genesA1andB1, which are in control of the entire plant coloration, allowed the creation of haploinducer lines with a frequency of haploid stimulation up to 15%. Phenotypic expression of dominant alleles of the marker anthocyanin coloration genes in different parts of a hybrid plant, as well as in the caryopsis and embryo, contributes to the high-quality selection of haploid kernels in the cob due to the manifestation of recessive alleles of these genes at the haploid level. The presence of anthocyanin synthesis suppressor genes in siliceous maize (C1-I,C2-Idf,In1-D) restricts the use of theR1-njgene in other representatives of siliceous maize. In order to overcome this problem, studies are underway to create other genotypes of haploinducers, which are not associated with the anthocyanin coloration of the caryopsis, but instead have other marker traits, such as the oil content in the kernel, the absence of ligules in the leaves, and root coloration in seedlings. The use of matroclinous and androclinous types of haploinduction allows breeders to obtain highly homozygous dihaploid maize lines, with both the maternal and paternal genomes. These achievements made it possible to cut five or more times the material and time inputs into the creation of inbred lines and their sterile analogs, accelerate the breeding of new maize hybrids, and signifi cantly improve the quality of seed production in terms of typicality and uniformity. The materials presented in the article should help breeders and geneticists to learn more about the innovative directions and problems of hybrid maize breeding.
Trombosis porto-mesentérica aislada secundaria a trauma abdominal cerrado
Authors: Vélez Leal Juan Luis , López Vélez Leidy Carlina
Published: December 2020

En este artículo se revisan los aspectos más importantes de la epidemiología, fisiopatología, abordaje diagnóstico y terapéutico de la trombosis del sistema venoso portal y mesentérico, para finalizar discutiendo la experiencia clínica de un caso a la luz de la literatura relevante.

Esta complicación es usualmente relacionada con afecciones sistémicas y hepáticas, pero rara vez se presenta aislada y relacionada con el trauma. En ausencia de tratamiento adecuado durante la etapa aguda, la trombosis puede evolucionar hacia el infarto intestinal y la muerte del paciente. En casos crónicos, se ha asociado con la degeneración del sistema venoso portal hacia cambios por hipertensión portal crónica.

Introducción. Al realizar una gastrectomía distal, el remanente gástrico es irrigado por los vasos gástricos cortos. En este estudio presentamos una serie de casos de gastrectomía distal laparoscópica, con la variante de preservar la rama superior de la arteria gástrica izquierda, con un remanente gástrico pequeño.

Métodos. Estudio observacional con intensión analítica, seguimiento de una cohorte retrospectiva de pacientes con cáncer gástrico sometidos a gastrectomía distal radical laparoscópica entre enero 2017 y junio 2019. Se incluyeron todos los pacientes con cáncer gástrico a quienes se les realizó gastrectomía distal radical por laparoscopia. Se estudiaron variables clínicas de los pacientes, variables intraoperatorias, información relacionada con el informe de patología y las complicaciones de la anastomosis gastro-yeyunal.

Resultados. Se revisó un total de 61 historias clínicas de pacientes sometidos a gastrectomía distal por laparoscopia, entre quienes se encontró la preservación de la rama ascendente de la arteria gástrica izquierda en el 73,8 % de los pacientes (n=45). El promedio de ganglios resecados fue de 24. Se presentaron un total de 10 complicaciones, ocho relacionadas con la anastomosis (tres estenosis, cuatro filtraciones y un paciente con hemorragia del tracto digestivo superior), y dos con colecciones intrabdominales. En el análisis estadístico no se encontró relación entre la preservación de la rama ascendente de la arteria gástrica izquierda con la presencia de complicaciones.

Discusión. La variación que presentamos de la técnica de la gastrectomía distal por laparoscopia cumple con los requisitos oncológicos en los pacientes con cáncer gástrico y no se relaciona con complicaciones de la anastomosis gastró-yeyunal.

Introducción. Los protocolos de recuperación mejorada después de cirugía se han diseñado como una innovación en salud tras demostrarse que la mejora en los dispositivos médicos y la depuración de técnicas alcanzaron la meseta en disminución de complicaciones. Con estas estrategias de la medicina perioperatoria, en cirugía colorrectal se reducen la morbilidad y estancia hospitalaria. El objetivo del estudio fue evaluar si la tasa de adherencia al programa de recuperación mejorada después de la cirugía (ERAS) está asociada con los resultados quirúrgicos.

Métodos. Estudio multicéntrico, observacional, retrospectivo de cohorte (2015-2019), en cinco hospitales latinoamericanos certificados por la sociedad ERAS. Se calculó la incidencia de complicaciones quirúrgicas durante el posquirúrgico inmediato (30 días) y la duración de la estancia hospitalaria. Se utilizaron análisis bivariado y regresión logística multivariada para evaluar los factores asociados con la tasa de complicaciones.

Resultados. Fueron incluidos en el estudio 648 pacientes en cinco hospitales ERAS, con edad promedio de 61 años y mayor porcentaje de hombres (51 %). El cumplimiento global al protocolo ERAS fue de 75 % y la estancia promedio de 6,2 días (mediana: 4 días). Se tuvo un cumplimiento óptimo del protocolo ERAS (igual o mayor al 80 %) en 23,6 % de los pacientes. Se documentó fuga de la anastomosis en 4 %, complicaciones infecciosas en 8,4 %, íleo en 5,7 %, reingreso en 10,2 % y mortalidad de 1,1 %. El análisis multivariado mostró que los niveles de adherencia óptima al protocolo ERAS reducen significativamente la aparición de complicaciones como fuga de la anastomosis (OR 0,08; IC95% 0,01-0,48; p=0,005) y complicaciones infecciosas (OR 0,17; IC95% 0,03-0,76; p=0,046).

Discusión. Los resultados sugieren que un cumplimiento del programa ERAS mayor al 80 % se asocia a menor frecuencia de complicaciones en pacientes con cirugía electiva colorrectal.

Authors: Bibi Tahira
Published: December 2020

Emotional Labor theory of Hochschild, 1983 and Grandey, (2002, 2015 & 2017) provided as basis of current research that gives the regulation of emotions at workplace categorized the main two dimensions of EL as Surface Acting (SA) and Deep Acting level of the school leaders. Self developed Emotional Labor Measurement Scale for School Leaders (ELMS-SL) was used to measure the EL level of the public sector school leaders. Multi stage sampling technique was used to select the sample of 376 (male=194, 52% and females=182, 48%) school leaders working in public sector secondary schools of 19 district of Punjab province. The core objective of the research was to measure the EL level and contribution of demographic variables (gender, mode of job induction, marital status and work experience) towards the emotional regulation status through suppression of emotions and modification of feeling. To measure the EL level of public sector school leaders, data were analyzed by using descriptive statistics, as well as t-tests, and ANOVA tests. The results revealed that public sector school leaders are practicing emotional labor. EL practices between male and female were significant difference, whereas mode of induction, marital status and job experience were found non-significant differences on EL.Key words: Emotional Labor, Surface Acting, Deep Acting, School Leaders, Demographic variables

Published: December 2020

In Pakistan about 2.49% of population is with special needs (Govt. of Pakistan, 1998) including hearing, visual impairment, mentally challenged, physically handicapped and multiple handicaps.  Only 1% of this population has access to education and higher education is almost not in access. Formal universities have no capacity, arrangements and skills to include the students with special needs. Open and Distance Learning is most suitable and accommodative mode for them so much of them are getting education through ODL mode. Allama Iqbal Open University is only public sector ODL University in Pakistan and providing free education to disadvantage group people included special need students. More than 400 special need students enrolled in different programs and most of them hearing impaired, visual impaired and physically disabled. But there are number of students emotional, social and behavioural disordered. The study aim was to determine the e-tutors/e-instructors arrogances to include students having emotional, social and behavioural difficulties (ESBD) seeing the impact of physical age, know-how, academic education/degrees and the help they had from AIOU.  Additional it was explored the connection between willingness and attitudes to be with ESBD students at ODL classroom/system whereas exploring the obstacles in effective inclusion of ESBD. Researcher selected 200 e-tutors/e-instructors as sample (100 male, 100 female) volunteered to take part on the study and most of them from Islamabad region. The study was mixed design i.e. quantitative and qualitative methods. Data collected in the form of numbers was by questionnaire of two scale and the qualitative through open ended questions.  Correlation was used to discover the relationship between physical age, professional practices (experiences), academic education and help they had with arrogances and readiness. The researcher used the thematic analysis to analyse the qualitative data/information. Findings of the study directed that physical age, experiences and help they had been significant predicators. Attitudes of e-tutors had good impact and relationship when they had help from the AIOU in the form training, assistant teachers and financial support. In interviews e-tutors responded that sometime they felt pre-service training programs didn’t equip them to accommodate needs of special students and how to include in ODL. Also they said resources should be available all the time rather than sometime available and sometime not. The study recommended that tutors should be trained to assess the special needs and characteristics of emotional, social and behavioural disordered students. Also modified teaching methods/pedagogies should be part of their pre and in-service teacher training progarmmes.    Keywords: ODL Teachers/Tutors, Inclusion, Special Need Students

THE EFFECT OF MICROWAVE ELECTROMAGNETIC FIELD ON THE HARDNESS OF CARBON FIBER-REINFORCED PLASTIC WITH LIGHTNING PROTECTION GRID DISTRIBUTED IN THE SURFACE LAYER
Authors:   Yuri Gagarin Saratov State Technical University, ZLOBINA I.V.
Published: December 2020

Based on the analysis of scientific and technical literature and trends in the development of multi-purpose aircrafts, we can see a steady extension of the use of polymer composite materials (PCM) in their design. The importance of lightning protection is noted for aircrafts, the skin of which consists mainly of the PCM, and it is shown that one of the common means is a lightning protection coating (LPC) in the form of a metal grid distributed in the PCM surface layer. Anisotropy of PCM properties and reduced fracture toughness in comparison with metals necessitates the improvement of PCM compositions and technologies of their formation as well as the development of methods for final hardening treatment in the cured state, which can be effectively performed under the effect of microwave electromagnetic field. Consideration is given to the influence of a short-term exposure to microwave electromagnetic field on the stability of carbon fiber-reinforced PCM with PLC against impact loads, as well as on the surface hardness. Our findings show a decrease in the damaged area of the impact zone by 40-60% and the absence of microcracking and delamination as well as an increase in hardness by 7.8%. Particular emphasis is placed on a 3-fold decrease in the spread of hardness values after the microwave exposure, this indicating a significant increase in the uniformity of this important characteristic for the component performance. As a mechanism of these modifications, it is proposed to reduce the pore size and porosity and to increase the number of points of contact interaction between matrix and fiber agglomerates that ensure an increase in the structural density.

THE HISTORY OF CATHOLICISM IN BASHKORTOSTAN: A BRIEF HISTORIOGRAPHIC OVERVIEW
Authors:   R.G. Kuzeev Institute for Ethnological Studies, KRYZHANOVSKY F.A.
Published: December 2020

The article examines the main publications covering the centuries-old history of the Catholic Church in the lands of modern Bashkortostan, as well as partly affecting the interaction of local Catholic communities with coreligionists from other cities located in the South Urals, as well as in the Middle Volga region. Unfortunately, there are quite a few special studies on the history of this Christian denomination in our republic. Many works, in one way or another related to this issue, are of a general nature and contain a schematic listing of factual information, or are more devoted to the history of national communities, for which this religion is, to a certain extent, one of the most important elements of traditional ethnic culture. Here it is necessary to note, first of all, publications on the history of the Polish and German diaspora, which provide information about the participation of representatives of these communities in the creation of Catholic parishes and public associations associated with charity and education. At the same time, the significance of the confessional aspect is to a much lesser extent revealed in works on the history of Latvian immigrants from Latgale, Belarusians and Ukrainians from Volyn and Eastern Galicia, who, due to various circumstances, left their homes during the First World War, as well as other Catholic emigrants from Central and Western Europe, located in the Ufa province at the beginning of the XX century. In some articles on demography and striking features of social stratification, one can find indirect references to the presence of Catholics, but this information only It is noteworthy that most publications indicate the middle of the 17th century as the earliest dating of the appearance of believing Catholics in the South Urals, and evidence of missionary trips to the Eastern Hungarians during the 13th-15th centuries allows us to make hypothetical assumptions about their role in the life of the local religious community. It can be noted that the presence of a certain part of Catholics on the territory of Bashkiria during the 16th20th centuries. was associated with forced migration due to the fact that, as a result of military clashes, some of them were captured, as well as due to participation in activities that conflicted with the interests of the Russian leadership are considered, with a few exceptions, only in the context of the problem of the origin of the Bashkir people, most likely due to the modest results of the preaching.
