Authors: Mandasari Lola , Rahmadhani Elfi , Wahyuni Septia 
Published: December 2020

Tujuan dari penelitian ini adalah melihat gambaran umum efektivitas perkuliahan daring pada mata kuliah analisis kompleks selama masa pandemic Covid 19 ditinjau dari hasil belajar dan respon mahasiswa. Penelitian ini merupakan penelitian kualitatif deskriptif. Subjek pada penelitian ini adalah mahasiswa semester VI Tadris Matematika IAIN Takengon yang mengambil mata kuliah analisis kompleks. Efektivitas perkuliahan daring pada mata kuliah analisis kompleks ditinjau dari hasil belajar mahasiswa yang diperoleh mahasiswa pada akhir semester, dan respon mahasiswa yang diukur menggunakan angket secara online dengan menggunakan google form. Angket berisikan pernyataan terkait respon mahasiswa dengan menggunakan skala Guttman, dan kemudian dihitung persentasenya untuk menentukan kriteria interpretasi skala Guttman. Hasil penelitian menunjukkan bahwa 83 % mahasiswa tuntas belajar pada mata kuliah analisis kompleks, sisanya 17% tidak tuntas. Persentase rata-rata ketuntasan belajar mahasiswa yang mengambil mata kuliah analisis kompleks sebesar 78,75%, dengan tingkat capaian efektivitas “cukup efektif”. Hasil perhitungan persentase respon mahasiswa terhadap perkuliahan daring pada mata kuliah analisis komplek adalah 42% dengan kriteria interpretasi “cukup efektif”. Dari dua penemuan tersebut dapat ditarik kesimpulan bahwa efektivitas perkuliahan analisis kompleks secara daring masih dalam kategori “cukup efektif”, karena masih banyak kendala dan keterbatasan yang dihadapai oleh mahasiswa dan dosen dalam pelaksanaannya.

OVERVIEW OF MODERN APPROACHES TO SOLVING THE PROBLEM OF EXTENDED RADAR TARGETS RECOGNITION
Authors: Vetoshkin A. , Аrtikula A. , Britov D. 
Published: December 2020

The development of the theory and technology of radio location indicates the need to solve problems of radar recognition of targets by spatial parameters. This is due to the need to provide in promising radar stations (complexes) with a software overview of the required resolution to obtain three-dimensional images in all spatial coordinates.
The task of radar targets recognition, which is to assign the observed objects to the appropriate classes and types, is of considerable and growing interest. Different classes (types) of targets make up a certain alphabet, the choice of which determines not only the effectiveness of the use of recognition, but also the difficulties that arise in its implementation.
Currently, there are a large number of radar recognition algorithms. They differ in the stages of decision-making, the degree and nature of accounting for statistics of signs, obstacles and signals. Due to the fact that the secondary emission pattern of extended targets is multi-lobed, statistical algorithms are preferred.
The information used for radar recognition is contained in the set of received radar signals. However, most often for target recognition certain measured target features are used, which are compared in accordance with the recognition algorithms with known (reference) features.
The choice of recognition features is usually made heuristically. This set of parameters does not always allow providing the required quality of recognition. The synthesized algorithms work unstable or require unreasonably large computational costs due to a significant increase in the dimensionality of the feature space.
Analysis of known radar recognition algorithms of extended targets shows that they were developed under significant constraints.
At present, the tasks of point targets radar surveillance are most fully solved. The tasks of processing signals reflected from bodies of complex shape, given the difficulties of their formulation and solution are not fully explored.
It is promising to consider a set of radar surveillance tasks and the criteria used in them as a multicriteria task, the solution of which is associated with vector optimization of the location system as a whole.
ROCKET-PROPELLED ANTI-PERSONNEL GRENADE LAUNCHERS EQUIPPED WITH DIFFERENT WARHEADS

Published: December 2020

At present, the issue of creating means of destruction of domestic production in Ukraine, including rocket- propelled anti-personnel grenade launchers equipped with different warheads (thermobaric, assault, fragmentation and incendiary) is acute.
With the advent of new incendiary, thermobaric agents and explosives, the development of multi-purpose rocket-propelled grenade launchers has become one of the promising trends. All of the above is proven by the experience of the Anti-Terrorist Operation/Joint Forces Operation in eastern Ukraine.
Analysis of flame troops combat operations during the anti-terrorist operation showed the need to intensify efforts to develop new rocket-propelled anti-personnel grenade launchers with thermobaric, assault, fragmentation and incendiary warheads. Leading specialists from the Russian Federation and Western countries also came to this conclusion. Thus, in recent years in Russia there have been developed, passed state tests and adopted RGSH-1 with a modular warhead in the thermobaric version, RGSH-2 rocket projectile with thermobaric warhead and RPG-32 "Barkas" equipped with thermobaric or tandem cumulative grenade.
Nowadays, several enterprises of the defense complex, one of which is the ТОV "Vognyana Varta", are dealing with the creation of a modern domestic rocket-propelled anti-personnel grenade launcher in Ukraine. ТОV "Vognyana Varta" on its own initiative has been developing a rocket-propelled anti-personnel grenade launcher with different warheads using new incendiary, thermobaric mixtures and explosives.
The classification of rocket-propelled grenade launchers (flamethrowers) is carried out. The design of modern ammunition to rocket-propelled grenade launchers (flamethrowers) and types of warheads for them are considered. Calculations of a solid-propellant rocket engine for modern rocket-propelled grenade launchers (flamethrowers) are given.
Be Star Disks: Powered by a Nonzero Central Torque
Authors: Nixon C. J. , Pringle J. E. 
Published: December 2020

Abstract
Be stars are rapidly rotating B stars with Balmer emission lines that indicate the presence of a Keplerian, rotationally supported, circumstellar gas disk. Current disk models, referred to as “decretion disks,” make use of the zero-torque inner boundary condition typically applied to accretion disks, with the “decretion” modeled by adding mass to the disk at a radius of about 2% larger than the inner disk boundary. We point out that, in this model, the rates at which mass and energy need to be added to the disk are implausibly large. What is required is that the disk has not only a source of mass but also a continuing source of angular momentum. We argue that the disk evolution may be more physically modeled by application of the nonzero torque inner boundary condition of Nixon & Pringle, which determines the torque applied at the boundary as a fraction of the advected angular momentum flux there and approaches the accretion and decretion disk cases in the appropriate limits. We provide supporting arguments for the suggestion that the origin of the disk material is small-scale magnetic flaring events on the stellar surface, which, when combined with rapid rotation, can provide sufficient mass to form, and sufficient angular momentum to maintain, a Keplerian Be star disk. We discuss the origin of such small-scale magnetic fields in radiative stars with differential rotation. We conclude that small-scale magnetic fields on the stellar surface, may be able to provide the necessary mass flux and the necessary time-dependent torque on the disk inner regions to drive the observed disk evolution.

Published: December 2020

BACKGROUND: The increased risk of malnutrition is affected by food insecurity. Studies in adolescents still show mixed results.
AIM: This article aimed to evaluate the association between food insecurity and anthropometry measurements in studies involving adolescents.
MATERIALS AND METHODS: The databases used to obtain the literature were PubMed, ScienceDirect, MEDLINE, and PubMed Central. The keywords used were food security, food insecurity, hunger, malnutrition, obesity, adolescence, adolescents, teenagers, teens, and youth in studies published from 2010 to 2019. A total of 12 articles were used in this review.
RESULTS: The association between food insecurity and the incidence of malnutrition in adolescents in various regions is still diverse. Food insecurity had a negative correlation with BMI-for-age in three studies (33.3%), but one study (11.1%) showed the opposite result. Food insecurity was positively related to low height-for-age (stunting) in 50% of studies, while five other studies (55.6%) showed that food insecurity was not related to BMI-for-age or weight-for-age. Three studies (50%) showed that there was no association between food insecurity and height-for-age.
CONCLUSION: Longitudinal studies, such as Cohort studies, need to be conducted to ensure the actual relationship between food insecurity and nutritional status in various regions.

Uma das principais discussões em torno da modalidade profissional para a Área de Ensino reside na compreensão sobre o Produto Educacional (PE) e sua validação, considerando os critérios adotados pela CAPES para a Avaliação Quadrienal (2017-2020) da produção técnica-tecnológica (PTT). Em função dessa importância, durante o Seminário de Meio Termo da Área, em 2019, foram organizados Grupos de Trabalho (GT) de PE e Doutorado Profissional, que trabalharam de maneira integrada, com a finalidade de elaborar os conceitos em conjunto. A partir da definição de PE elaborada pela Área de Ensino, detalhamos algumas possibilidades de Produtos e Processos Educacionais que contemplam as tipologias já definidas em documentos da Área e que nesse trabalho foram organizadas tendo como referência o Relatório do GT Produção Tecnológica da CAPES de 2019. Assim, é apresentado neste artigo o relatório do GT com a compreensão sobre PE e uma proposta com critérios que visam à etapa de avaliação do Qualis Educacional. Com Seminário de Meio Termo e o estudo elaborado pelo relatório técnico da CAPES propomos um conjunto de conceitos que devem subsidiar a análise do PE. Esses conceitos são sintetizados em um modelo de formulário de validação com o objetivo de possibilitar uma validação unificada do PE por bancas de defesa de dissertação ou tese. Dessa forma, entendemos que uma discussão mais detalhada sobre PE pode conduzir a uma maior qualificação destes, permitindo que o trabalho desenvolvido nos Programas de Pós-graduação Profissionais tenha reflexos diretos na melhoria da Educação Básica.
DINÂMICAS GEOECONÔMICAS DA CADEIA PRODUTIVA DE SUCO DE LARANJA NA MESORREGIÃO NORTE PIONEIRO DO PARANÁ E O PAPEL DO BANCO NACIONAL DE DESENVOLVIMENTO ECONÔMICO E SOCIAL (BNDES)

Published: December 2020

A partir dos anos 2000, o Brasil passou por uma reestruturação em várias cadeias produtivas do setor agropecuário, resultado de novas conjunturas macroeconômicas, e principalmente por um Governo Federal com uma plataforma política de cunho desenvolvimentista, tendo o BNDES como principal agente direcionador de investimentos. Com isso, a Mesorregião Norte Pioneiro também passou por um processo de reestruturação produtiva no mesmo período, com a inserção de novas cadeias produtivas em seu território. Dessa forma, o presente artigo possui como objetivo demonstrar as dinâmicas geoeconômicas da cadeia produtiva do suco de laranja nessa região e a sua relação com o capital de crédito oriundo do BNDES. Para esse trabalho foram utilizados como instrumentos metodológicos a pesquisa bibliográfica e a pesquisa de campo. Os resultados apontam para novas dinâmicas geoeconômicas na região a partir da implantação da planta industrial de processamento de suco de laranja da Cooperativa Integrada em Uraí e a dinamização de demais elementos da referida cadeia no Norte Pioneiro e em outras localidades do Paraná e do Estado de São Paulo, atrelada a uma estreita relação com os capitais de investimento oriundos do BNDES.

Abstract
Vitamin D deficiency is associated with increased risks of chronic obstructive pulmonary disease (COPD). Nevertheless, the mechanisms remain unknown. This study analyzed the correlations between vitamin D levels and inflammation in COPD patients. One hundred and one patients with COPD and 202 control subjects were enrolled. Serum 25(OH)D level and inflammatory cytokines were detected. Serum 25(OH)D was decreased and inflammatory cytokines were increased in COPD patients. According to forced expiratory volume in 1 s, COPD patients were divided into three grades. Furthermore, serum 25(OH)D was gradually decreased in COPD patients ranging from grade 1–2 to 4. Serum 25(OH)D was inversely associated with inflammatory cytokines in COPD patients. Further analysis found that NF-κB and AP-1 signaling were activated in COPD patients. Besides, inflammatory signaling was gradually increased in parallel with the severity of COPD. By contrast, pulmonary nuclear vitamin D receptor was decreased in COPD patients. In vitro experiments showed that 1,25(OH)2D3 inhibited LPS-activated inflammatory signaling in A549 cells (human lung adenocarcinoma cell). Mechanically, 1,25(OH)2D3 reinforced physical interactions between vitamin D receptor with NF-κB p65 and c-Jun. Our results indicate that vitamin D is inversely correlated with inflammatory signaling in COPD patients. Inflammation may be a vital mediator of COPD progress in patients with low vitamin D levels.
Risk factors of admission in 72-h return visits to emergency department
Authors: Liu Sung-Wei 
Published: December 2020

Objective:
Return visit to emergency department (ED) is a common phenomenon and has been a clinical indicator of quality of care in ED. Most of previous articles focused on the characteristics of the patients returning within 72 h after ED discharge, while those on subsequent admission are numbered. This study's purpose is to identify risk factors for admission among 72-h return visit in the ED adult population.

Materials and Methods:
This retrospective cohort study was conducted at a medical center in Eastern Taiwan. The study period was from January 1, 2013, to December 31, 2013. We excluded patients who left against medical advice or without being seen, who was admitted or transferred at the index ED visit, whose medical records were incomplete, and whose age was below 18 years old. Significant variables were selected based on univariate analysis and later entered into multivariate logistic regression analysis to identify risk factors for 72-h return admission.

Results:
We identified 1575 eligible visits, and there were 1,119 visits entering into the final analysis. Male gender (odds ratio [OR] = 1.44), ambulance-transport at return visit (OR = 3.68), senior staff (OR = 1.52), work-up (OR = 3.03), and longer length of stay (LOS) were associated with higher risks of admission among ED 72-h return visits. Age, comorbidity, mode of transport at index visit, consultation, triage, type of illness, outpatient department visit between ED visits, and interval between index and return visits were not significantly associated with return admission.

Conclusion:
Gender, mode of transportation, staff experience, check-up, and LOS are associated with ED return admission.

Desafíos en la implementación a nivel local de los Objetivos de Desarrollo Sostenible en el Estado de Hidalgo, México / Challenges in the local implementation of the Sustainable Development Goals in the State of Hidalgo, Mexico
Authors: Ramírez Avilés José Iván 
Published: December 2020

A 5 años de la aprobación de la Agenda 2030, la tarea de implementación de cada uno de sus Objetivos, metas e indicadores, sigue siendo un tema pendiente, sobre todo a nivel local y en un contexto en el que se suma la reciente pandemia que aqueja a la humanidad y que obliga a acelerar con mayor hincapié las acciones hacia el desarrollo sustentable. En este sentido, este trabajo busca realizar una revisión sobre referencias metodológicas oficiales y de los pasos más formales desarrollados hasta este momento para la transversalización de los Objetivos de Desarrollo Sostenible. Se parte de una investigación primaria de gabinete de guías y documentos a nivel internacional y nacional, así mismo se replican y analizan algunos ejemplos, para el caso del Estado de Hidalgo, México. Se revisan los diferentes programas sectoriales y presupuestales (a nivel de Matrices de Indicadores de Resultado). Se identifica que, si bien hay un esfuerzo destacado por alinear los distintos programas a los ODS, se carece aún del uso de metodologías apropiadas para dar seguimiento riguroso, con indicadores homologados y validados para los reportes de la Agenda. Se requiere del fortalecimiento de estrategias y capacidades locales, debido a que es en este nivel de escala en el cual se presentan los principales retos en la articulación de metas locales y globales.
ABSTRACT
Five years since the 2030 Agenda’s approval, implementing each of its objectives, goals, and indicators is still a pending subject. We can observe this mostly at a local level, and also in these times’ context, considering the global pandemic we are facing nowadays also forces us to accelerate actions towards sustainable development. On this ambiance, this paper’s objective is to contribute by reviewing official methodology references and the most reputable steps taken on mainstreaming the Sustainable Development’s Objectives (SDG’s). The starting point lies in a primary investigation about different methodological guides developed internationally and nationally, as well as some replicated examples about the SDG’s implementation in Hidalgo State. An analysis of different institutions and budgetary programs -at the Results’ Index Counterfolls level- is made. We can observe that although a significant effort into SDGs mainstreaming is made, we still lack appropriate methods so verified and validated indicators can measure them for the Agenda reports. Strategies and local capacities require reinforcement since the main challenge on articulating global and local goals is found on this level. Keywords: Sustainable development, development indicators, public management, budgets, 2030 agenda.
