Authors: Mamonova Marina V. , Prudnikova Irina A.
Published: December 2020

In this work, the results of numerical first-principles calculations of the magnetic characteristics for Co and Fe monolayer films on Cu(100) and Pt(100) slabs by using the VASP software package are presented. The values of the difference in the total energy of antiferromagnetic and ferromagnetic configurations depending on the parameters of convergence and thickness of non-magnetic material are calculated. Favorable magnetic anisotropy energy and values of the magnetic moment of atoms in the Co/Cu/Co, Co/Pt/Co, and Pt/Co/Cu/Co/Pt structures are determined. The phenomenon of reorientation in the Co/Cu(100)/Co structure, when the in-plane anisotropy of the cobalt films changes to an out-of-plane anisotropy due to the incorporation of an ultrathin platinum film into the structure is confirmed.

Authors: Artyushina Olga V.
Published: December 2020

The subject. The algorithm of qualification of beatings is researched taking into account changes in the Russian legislation of Russia on the protection of bodily integrity of a person. The author studies the norms of Russian criminal and administrative legislation in the field of protection of human bodily integrity and practical issues that have emerged in this regard. The purpose of the article is to confirm or disprove the hypothesis of a complex (not obvious to the law enforcement officer) process of qualification of violent actions that caused physical pain, but did not cause harm to human health, due to the multi-level competition of legal norms. The methodological basis of the study is the general scientific dialectical-materialistic approach based on the methods of analysis and synthesis, induction and deduction. Logical, system-structural, concrete sociological and comparative legal methods are also used. The research materials are data from judicial practice on liability for beatings and related crimes. The main results, scope of application. Beatings are considered as violence that is not dangerous to life or health. The norms that can be applied when the perpetrator commits the corresponding violent actions are identified. The differences between beatings and lawful infliction of harm, minor acts, and attempted crimes are shown. A distinction is made with related elements of crimes against life and health, constitutional rights and freedoms, interests of minors, property, etc. The presentation is based on the author's systematization of the rules for qualifying beatings and taking into account the sequence of steps for making the final decision by the law enforcement officer. The results of the research may be applied in higher legal education, further academic researches concerning beatings as well as in law enforcement practice of criminal investigations. Conclusions. The author explains the difficulties in qualifying beatings. The rules of legal assessment of violent actions that caused physical pain, but did not cause harm to health, in the competition of criminal law norms are shown. The algorithm for qualifying beatings according to the current legislation of Russia is derived.
Performance information – the critical issue of public finance legal regulation
Authors: Shokhin Sergey O. , Kudryashova Ekaterina V.
Published: December 2020

The subject. The paper is focused on the study of the role of performance information in the decision-making process on public finance with particular accent on the legal aspects of the issue. The purpose. We aim to show that the performance results have a little impact on the public finance allocation in the next management cycle. Nowadays the financial resolutions are taken not on the basis of the results, but apart from them. The problem can be identified in many countries and currently discussed on the international level. We make an attempt to identify the main reasons for this. The research is elaborating the possible solutions for the problem and presenting possible amendments to the legislation. The methodology. The multidisciplinary approach is employed in this research as the problem is covered by different social sciences like law, economics and politics. The methods of analysis and synthesis are relevant for this paper. The examples and illustrations from different countries all over the world constitute the empirical part of the article. The main results and conclusions. The key reason for the omission or misuse of performance results in public finance is the passive role of the user of the performance information. There is a lack of legal incentives for using the performance results for those who take the financial decisions. Those who take the decisions in public finance governance should have an obligation to assess the performance information and use it for the further resolutions. Scope of the research outcome application. This research shall have substantial impact on the development of adequate legal model for the performance information use in public finance allocation. If the legal obligation to use the performance information is introduced it will have positive impact on the legal regulation of public finance in Russia. This can be relevant for the international studies of the issue and for the legal regulation of financial governance in other countries as well.
The Comparison of Land Subsidence between East and West Side of Bangkok, Thailand
Authors: Pumpuang Angkana , Aobpaet Anuphao
Published: December 2020

The land deformation in line of sight (LOS) direction can be measured using time series InSAR. InSAR can successfully measure land subsidence based on LOS in many big cities, including the eastern and western regions of Bangkok which is separated by Chao Phraya River. There are differences in prosperity between both sides due to human activities, land use, and land cover. This study focuses on the land subsidence difference between the western and eastern regions of Bangkok and the most possible cause affecting the land subsidence rates. The Radarsat-2 single look complex (SLC) was used to set up the time series data for long term monitoring. To generate interferograms, StaMPS for Time Series InSAR processing was applied by using the PSI algorithm in DORIS software. It was found that the subsidence was more to the eastern regions of Bangkok where the vertical displacements were +0.461 millimetres and -0.919 millimetres on the western and the eastern side respectively. The districts of Nong Chok, Lat Krabang, and Khlong Samwa have the most extensive farming area in eastern Bangkok. Besides, there were also three major industrial estates located in eastern Bangkok like Lat Krabang, Anya Thani and Bang Chan Industrial Estate. By the assumption of water demand, there were forty-eight wells and three wells found in the eastern and western part respectively. The number of groundwater wells shows that eastern Bangkok has the demand for water over the west, and the pumping of groundwater is a significant factor that causes land subsidence in the area.Keywords: Subsidence, InSAR, Radarsat-2, Bangkok

Authors: Wintolo Hero , Farhati Amalia
Published: December 2020

Digital libraries have been widely applied in educational institutions in Indonesia as a complement conventional libraries. The purpose of this research is to know division computer network access at the Adisutjipto Intitute of Technology (STTA) library. The research method used is a qualitative method using Prepare Plan Design Implement Operate and Optimize (PPDIOO). The result research is that people who have internet access will not be able to enter the digital library network. Computer network users who want to access digital libraries must log into the computer network that provides digital books in the library using a Virtual Local Area Network (VLAN). Making this VLAN requires a computer network infrastructure in the form of a Local Area Network (LAN) and computer network equipment in the form of a switch that can be used to configure multiple VLANs in a LAN. Some of the existing services in the library are placed on one VLAN and the digital library is placed on another VLAN. From the test results, it can be seen that between computers that provide services in the library on VLAN 2 cannot communicate via the connecting network to VLAN 1 where the digital library with website based services will be located. This is evidenced by the ping command which generates request time out information. VLANs network in the STTA library have been able to provide support for plans to improve services to members and academicians in the form of a digital library.

Strategi pengembangan Usaha Mikro Kecil Menengah (UMKM) di Kota Malang melalui literasi informasi
Authors: Shobaruddin Muhammad
Published: December 2020

This study examined Micro, Small, and Medium Enterprises (MSMEs) development strategies through information literacy. Information literacy can be interpreted as expertise in effectively accessing and evaluating information to solve problems and make decisions. This study aimed to improve the quality of human resources driving MSMEs in Malang through information literacy. Descriptive qualitative methods were used to describe the phenomenon as a whole. Data were collected through Focus Group Discussions (FGDs) to determine the pattern of problem identification, searching and implementing solutions, and applying information literacy to the UMKM process in Malang City. The FCD results were analyzed by identifying problems, solutions that were implemented, and information literacy application. The next step was to formulate the stages of the MSME development strategy. MSMEs in Malang City faced internal (capital, human resources, and infrastructure) and external (government support, community roles, and consumer response) constraints. The solutions implemented to overcome these obstacles have not thoroughly utilized information literacy skills, so the problem recurs. MSME development strategies that can be applied with third parties' assistance are problem identification, reflection on applied solutions, and development of information literacy skills (the ability to access information, sort and select, and understand and implement it). Based on these findings, the role of third parties, such as the government and the research team, is quite important for implementing strategies and improving the quality of MSME Human Resources.

Temuan penelitian ini memberikan masukan kepada lembaga-lembaga sosial dan para pelaksana intervensi sosial bahwa untuk mengurangi kemungkinan remaja putri membuat keputusan menjadi TKW, mereka perlu memperhatikan program intervensi yang menekankan pada aspek ‘bagaimana meningkatkan harga diri’ remaja putri.
Expansión urbana, humedales y evolución en los usos del suelo en el Gran La Plata
Authors: López Isabel , Rotger Daniela
Published: December 2020

Junto con la fundación de la ciudad de La Plata, en tierras aledañas de muy buena calidad se previeron actividades agropecuarias, que no sólo abastecen hasta la actualidad a las ferias barriales, sino que este cinturón productivo provee de productos frescos al Gran La Plata y la Región Metropolitana de Buenos Aires. La tecnología empleada para la producción de alimentos ha cambiado sustancialmente, así como la utilización del suelo, en la que compiten en extremo la presión urbanizadora y las actividades hortícolas y florísticas. Los instrumentos de planificación en la ciudad no acompañaron el desarrollo de la producción intensiva, y lo urbano fue extendiéndose sobre lo rural, ocasionando la pérdida de diversidad en los cultivos y el deterioro de valiosos ecosistemas, como los bañados de desborde fluvial. El objetivo de este artículo es realizar una revisión de los conflictos ambientales que han llevado al deterioro de los ecosistemas y el suelo en la ciudad, considerando como unidades ambientales-territoriales las sub-cuencas de arroyos, abordando las estrategias que podrían emplearse para mejorar la calidad de vida en las áreas periurbanas y rurales. La contigüidad en forma de ciudad difusa desde el urbanismo, sobre los bañados o cañadas que dan origen a los arroyos, así como el uso de agroquímicos y la falta de servicios básicos, aumenta la degradación ambiental, el riesgo de inundación por falta de superficie de infiltración, anula los servicios ecosistémicos contribuye a la reducción o desaparición de los humedales. Es necesario promover la coexistencia de ambos ámbitos, siendo que lo rural puede favorecerse de la accesibilidad que otorga lo urbano, que incorpora vías de comunicación y transporte público.

Published: December 2020

Se estudia la relación entre el tipo de cambio nominal y la difusión de noticias macroeconómicas en Argentina mediante la estimación de un modelo VARX-GARCH(1,1). Los principales resultados empíricos indican que: 1) La transmisión de shocks financieros adversos procede fundamentalmente desde Estados Unidos y opera mediante el spread de tasas de interés (EMBI+ para Argentina); 2) Las noticias recopiladas de periódicos locales y extranjeros no ejercen efectos económicos relevantes para explicar la dinámica del tipo de cambio nominal; y 3) La volatilidad condicional de los shocks aleatorios asociados a las variables endógenas del modelo VARX puede formalizarse mediante una estrategia GARCH(1,1).

Authors: Sans Mónica , Figueiro Gonzalo , Bonilla Carolina , Bertoni Bernardo , Cappetta Mónica , Artagaveytia Nora , Ackermann Elizabeth , Mut Patricia , Hidalgo Pedro C.
Published: December 2020

Diversos estudios genéticos han demostrado que la población uruguaya es trihíbrida, formada por europeo/mediterráneos, indígenas y africanos, cuyo aporte varía en distintas regiones del país. Pese a que Montevideo es la capital de la República, hay escasos estudios sobre los orígenes de su población, que pueden diferir de otras regiones. En este trabajo se propone indagar sobre estos orígenes a partir de información genética en una muestra derivada de una previamente publicada, profundizando en algunas características para determinar su posible influencia en la estimación de la ancestría. Se consideró una muestra de 269 mujeres (casos y controles de un estudio de cáncer de mama) en quienes se analizaron haplogrupos y secuencias de las regiones hipervariables del ADN mitocondrial (ADNmt) y marcadores individuales de ancestría (AIMs) del ADN nuclear. Se observó que había diferencias en los porcentajesde ancestría cuando se analizaban separadamente las personas que se atendían en el sistema público de salud en relación a las que lo hacían en el sistema mutual, con diferencias significativas para el aporte indígena y el europeo/mediterráneo. Luego de corregidos los valores por lugar de atención de salud, se estimaron los siguientes aportes: 24.6% indígena, 67,7% europeo/mediterráneo y 7,7% africano para herencia materna, y de 11,1% indígena, 81,4% europeo/mediterráneo, y 7,5% africano para la herencia biparental. Se analizaron particularmente los aportes indígena y africano y se discutieron los resultados con relación a otros estudios. Debido a las diferencias encontradas relacionadas con la heterogeneidad de la población montevideana, se alerta sobre el muestreo y valores de referencia para estudios poblacionales futuros.
A SISTEMATIZAÇÃO DO CONHECIMENTO COMO FATOR DE CONSERVAÇÃO SOCIAL
Authors: Sene Túlio Silva
Published: December 2020

Partindo da percepção de que os sistemas de ensino podem ser interpretados como fatores de conservação social, este trabalho debruça-se sobre as ideias de progresso e desenvolvimento e o seu papel na construção do ideário econômico liberal. Busca-se compreender como a sistematização do ensino na era moderna associou-se com os interesses das classes dominantes para produzir regras de caráter universalista que tendem a legitimar as relações de poder estabelecidas. Revela-se que, apesar das diferentes terminologias, há uma continuidade no que se refere à utilização de saberes científicos supostamente irrefutáveis como instrumentos de legitimação da ordem. Discute-se também a retórica do desenvolvimento e da cooperação como instrumento de legitimação dos ganhos desiguais e dos diferentes ritmos de crescimento econômico. Por fim, conclui-se que a associação entre ensino e poder se manifesta por meio da propagação de postulados unidimensionais, supostamente objetivos e universais, para legitimar as desigualdades e naturalizar os fenômenos sociais.

Authors: Silva Wilney Fernando , Quillici Neto Armindo
Published: December 2020

A proposta deste artigo é investigar a influência da Igreja Católica nas práticas corporais do Grupo Escolar João Alcântara, em Porteirinha/MG, entre 1930 a 1945. Para a Igreja, a educação foi uma poderosa estratégia no que diz respeito à expansão e à manutenção da sua hegemonia, e, por meio da sua doutrina, ela propôs a educação corporal de crianças, jovens e mulheres para que pudessem somar forças à religião. Para a constituição dessa tarefa, foi realizada a análise de fontes documentais em livros de reuniões de professores, recortes de jornais, fotografias, livros do Tombo de diversas paróquias e legislação educacional. Como resultado, pode-se afirmar que a educação do corpo dava suporte à educação da mente e da moral. Com isso, o esporte passou a ser um aliado interessante para uma proposta de um Estado e de uma Igreja que se diziam, dentro dos seus domínios, unitários, fortes e racionalizadores.

Published: December 2020

In this study, the effect of vacuum cooking conditions (temperature and time) on the color, textural, microstructural and sensory quality of beef samples was investigated. In order to determine the optimum cooking temperature (60-90ºC) and time (80-120 min) for beef, an optimization study was carried out following Central Composite Rotatable Design (CCRD). The optimum vacuum cooking condition was selected as 85.6°C of cooking temperature and 106.6 min of cooking time targeting maximum chewiness (textural quality), minimum shear force (textural quality) and maximum sensory overall acceptance attributes. Considering the color values of crust and inner parts of beef samples, an insignificant difference was observed among cooking temperatures and times. However, Warner Bratzler shear force values decreased with an increase in cooking temperature. Moreover, higher cooking temperature and longer cooking time resulted in superior sensorial properties in terms of overall acceptance scores.

Gallant soldier (Galinsoga parviflora Cav.) is a cosmopolitan weed and is traditionally used as a vegetable in Java highland. The study aimed to evaluate agroecology and uses of G. parviflora as an indigenous vegetable in Java. Researches were conducted in Kuningan, Banjarnegara, and Wonosobo districts from June 2015 to July 2017. The distribution map was drawn from field tracks, interviews, and literature studies. Results revealed two Galinsoga species based on leaf and stem shape, i.e., G. parviflora and G. quadriradiata. Only G. parviflora was selected as a vegetable in Banjarnegara and Wonosobo, but not in Kuningan district. It ranked seventh among 13 traditional vegetables; young shoot with inflorescences was consumed after cooking or boiling, and sometimes used as a diuretic. Although it contributed low to household diet, however, its position on the social relationship among neighbors was important. The wide distribution range of Galinsoga in Java is potential as a new vegetable. It is important to study the nutrient content of this vegetable to improve utilization.

Karakter kualitas tersebut meliputi diameter umbi, berat jenis, bahan kering, dan organoleptik keripik. Penelitian dilaksanakan pada Januari-Mei 2020 di Desa Margamulya, Kecamatan Cikajang, Kabupaten Garut. Sebanyak delapan genotipe yang terdiri atas PKHT-2019-010, PKHT-2019-011, PKHT-2019-012, PKHT-2019-013, PKHT-2019-014, PKHT-2019-015, PKHT-2019-016, PKHT-2019-017 dan dua varietas pembanding yaitu Medians dan Intan. Rancangan percobaan yang digunakan pada penelitian ini adalah rancangan kelompok lengkap teracak faktor tunggal yaitu genotipe dengan 4 ulangan. Penelitian dimulai dari persiapan lahan, penanaman, pemeliharaan, dan pemanenan, serta pengolahan keripik. Hasil penelitian menunjukkan bahwa genotipe PKHT-2019-010, PKHT-2019-012, dan PKHT-2019-017 memiliki potensi sebagai genotipe yang dapat dikembangkan sebagai varietas kentang untuk bahan baku industri keripik kentang berdasarkan berat jenis, kandungan gula, bentuk, penampilan dan warna keripik yang baik. Genotipe PKHT-2019-015 memiliki produktivitas, bobot umbi dan diameter umbi yang sangat baik dan memenuhi kriteria industri, namun memiliki kadar gula yang tinggi sehingga lebih cocok dikembangkan sebagai kentang sayur. Namun demikian masih diperlukan penelitian lanjutan untuk meningkatkan bobot dan ukuran ketiga genotipe tersebut untuk mencapai standard industri.

Drug shortages has been global problem since 2000s until now, and it become in serious condition by the presence of the pandemic COVID-19. The main causes of drug shortages were economic and regulation, business problem, manufacture and supply chain. During this pandemic, the main causes of drug shortages are many pharmaceutical industries closures due to quarantine, logistical problems caused by border closure, export bans, quarantine of exporting active subtances and drugs’countries, increased demand and pilling up. However, this problem has been overcome by making policies and good cooperation between governments, regulatory institution and the pharmaceutical industry throughout the world. Several policies like increasing production capacity, restrict quantity of drugs purchased by the public, facilitate the process of industrial license and making a systems such as i-SPOC (Industry Single Point of Contact).  It is expected to reduce drugs shortages problem during this pandemic.

ABSTRACT

Neuroinflamation is a neurodegenerative disease caused by estrogen deficiency. Marsilea crenata Presl. is a plant that contains phytoestrogens, which are compounds that can replace the function of estrogen in maintaining cell homeostasis in the brain. The purpose of this study was to predict the antineuroinflammatory effect of 96% ethanol extract of cultivated Marsilea crenata Presl. leaves in HMC3 microglia cells through activated ER measurements, and observed using the immunocytochemistry method. IFN? is induced into cells 24 hours before treatment to cause an inflammatory condition. 96% ethanol extract of cultivated Marsilea crenata Presl. leaves is given at a dose of 62.5; 125; and 250 ?g/ml. Genistein 50 ?m was used as a positive control. The results showed that 96% ethanol extract of cultivated Marsilea crenata Presl. leaves at doses of 125 and 250 ?g/ml can decrease free ER? expression with values ??of 814,216 and 573,190 AU at p <0.05, and shows an increase in the amount of activated ER?. From these results it can be concluded that the 96% ethanol extract of cultivated Marsilea crenata Presl. leaves provides a potential antineuroinflammatory effect shown by the decreasing of free ER? expression on HMC3 microglia cells with 250 ?g/ml as the best dose.
