Published: May 2021

Tujuan pelaksanaan program kemitraan masyarakat berupa pelatihan ini adalah untuk meningkatkan kompetensi guru di Indonesia menciptakan, mengembangkan dan mengimplementasikan media pembelajaran berbasis ICT menggunakan Lectora Inspire. Pelatihan ini dilaksanakan pada guru sekolah dasar yang berada di Kecamatan Japara Kabupaten Kuningan. Persoalan pembelajaran pada mitra adalah guru jarang menggunakan media pembelajaran yang interaktif saat pembelajaran di kelas. Hal tersebut membuat motivasi peserta didik cenderung rendah. Padahal sebagaimana diketahui bahwa tuntutan kurikulum 2013 dan pesatnya IPTEKS mengharuskan guru kreatif menggunakan media pembelajaran berbasis ICT. Potensi guru-guru sekolah dasar di kecamatan Japara cukup besar dan keberadaan perangkat teknologi di sekolah cukup memadai namun dari segi kompetensi perlu terus ditingkatkan. Kompetensi tersebut salah satunya adalah kemampuan pembuatan media pembelajaran menggunakan ICT yang masih sangat minim. Hal ini dikarenakan belum adanya kegiatan pelatihan khusus pembuatan media pembelajaran berbasis ICT. Solusi dari permasalahan tersebut adalah dilaksanakannya pelatihan pembuatan media pembelajaran berbasis ICT menggunakan Lectora Inspire. Kegiatan pelatihan ini terdiri dari tahapan sebagai berikut: 1) survey lapangan (mitra); 2) Koordinasi dengan kepala sekolah dan guru; 3) Sosialisasi Program; 4) Pelaksanaan Program; dan 5) Evaluasi kegiatan.

Published: May 2021

O pirarucu apesar de suas características adaptativas particulares que favorecem seu cultivo em viveiros escavados e sob altas densidades de estocagem, a obtenção do máximo potencial zootécnico vem sendo prejudicada principalmente pela influência da qualidade de água. Por isso, o objetivo com esse trabalho foi caracterizar a qualidade da água em um ciclo de cultivo do pirarucu (Arapaima gigas). O estudo foi realizado no Centro de Pesquisa em Piscicultura Carlos Eduardo Matiazze, Universidade Federal de Rondônia, Presidente Médici-RO. Onde foram mensurados os parâmetros limnológicos nas fases de cultivo de 60 pirarucus em viveiro subdivido em hapas e em tanques rede. Os resultados obtidos foram comparados com o estabelecido pelas Resoluções CONAMA n° 357/2005 (BRASIL, 2005) e nº 430/2011 (BRASIL, 2011), verificando os dados obtidos conforme sua classe de enquadramento de uso (piscicultura). A qualidade da água sofreu influência direta da fase de cultivo do pirarucu em todos os ciclos de cultivo devido ao manejo adotado no viveiro. Foram encontrados valores adequados para oxigênio dissolvido, pH e temperatura da água foram obtidos quando houve menor biomassa no viveiro e na fase de crescimento até 4,5 kg de peso do pirarucu.
Parenting Styles During the Covid-19 Pandemic: A Conception of Islamic Family Law
Authors: Baharuddin H
Published: May 2021

The covid-19 pandemic situation has led to many changes in living conditions and various activities that are mostly carried out at home in order to reduce and prevent the chain of transmission of the corona-19 virus. This study aims to provide an illustration of the role of parents at home during the Covid-19 pandemic situation by providing the rights that must be given to children by correlating them with the concept of childcare in Islamic family law. The urgency in education studies in the review of Islamic family law is to emphasize the position of parents who are not only responsible for providing a living, including in matters of success in education. This is a conceptual study, which seeks to explore the concept of childcare that is built in Islamic family law. The findings in this study indicate that childcare according to Islamic family law in the covid-19 pandemic situation, namely: 1) teaching children to do good and keep away from badness, this is done by way of parents giving examples and accompanying children when learning, 2) Parenting with affection, this care is done by providing safety and guidance to children, 3) Fulfilling the needs of children. In the conception of Islamic family law it is known as hadanah rights or child care which is widely understood, both in terms of livelihood to children's intelligence. The implication of this finding is that during the pandemic, parents have a significant role, in addition to living needs, parents are also required to ensure children's intelligence through the fulfillment of education.

В статье рассматриваются социально-демографические и экономические факторы, которые связаны с транспортным освоением северных прибрежных районов Тихоокеанской России. Анализируются природные условия и факторы, сдерживающие развитие транспортной инфраструктуры в районе исследования. Отмечено, что выделенные нами районы в ряде инвестиционных проектов имеют стратегическое значение как одно из главных звеньев транспортного соединения западной с северо-восточной частью России. Дано описание состояния современной транспортной инфраструктуры муниципальных районов и городских округов, расположенных на российском тихоокеанском побережье. Приведены показатели социально-экономического положения исследуемых районов. Указано что, с одной стороны, «очаговостъ» освоения усложняет развитие транспортных сетей. С другой стороны, за счёт ряда факторов существует возможность в ряде районов развивать транспортную инфраструктуру. При намечаемых проектах и возможных перспективах развития транспортной инфраструктуры главными видами транспортной деятельности остаются морской и воздушный.

The article addresses socio-demographic and economic factors that are associated with the transport development of the northern coastal regions of Pacific Russia. The natural conditions and factors restraining the development of transport infrastructure in the study area are analyzed. It is noted that the areas we have identified in a number of investment projects are of strategic importance as one of the main links in the transport connection between the western and northeastern parts of Russia. The condition of the modern transport infrastructure of Russian municipal districts and urban districts located on the Pacific coast is described. Indicators of the socio-economic situation in the study regions are presented. It is indicated that, on the one hand, uneven development complicates the expansion of transport network. On the other hand, due to a number of factors, it is possible to build transport infrastructure in a number of regions. With the planned projects and possible prospects for the development of transport infrastructure, the main types of transport remain maritime and air.

Authors: Росликова В.И.
Published: May 2021

Исследованы почвы зон отдыха центральной части г. Хабаровска. Сложность инженерно-геологических условий предопределило неоднозначность антропогенных воздействий и различие техногенного морфолитогенеза. Это нашло отражение в степени трансформированности почвенного покрова и экологического состояния. Степень загрязнения его тяжелыми металлами по данным усредненных оценок их содержания находится в пределах допустимых значений. При этом локальные участки достаточно напряжены, где индикатором такого состояния является чувствительность зеленых насаждений. Вусловиях интенсивного антропогенного воздействия оценка по суммарному показателю величин содержания тяжелых металлов не достаточно информативна, так как состояние локальных загрязненных участков нивелируется. Это свидетельствует о необходимости проведения более глубоких исследований почв с учетом ее базовых составляющих.

The soils of recreation areas in the central part of Khabarovsk were studied. The complexity of engineering and geological conditions predetermined the ambiguity of anthropogenic impacts and the difference in technogenic morpholithogenesis. This is reflected in the degree of transformation of the soil cover and the ecological state. The degree of its contamination with heavy metals according to the average estimates of their content is within acceptable values. At the same time, local areas are quite tense, where the sensitivity of green spaces is an indicator of this state. In conditions of intensive anthropogenic impact, the assessment of the total value of the heavy metal content is not sufficiently informative, since the state of the local contaminated areas is leveled. This indicates the need for more in-depth studies of the soil, taking into account its basic components

Published: May 2021

Обсуждается понятие полиструктурности ландшафтного пространства. Объект исследований – остров Матуа с активным вулканом, отсутствием поверхностного стока и широким развитием селевых и лавинных комплексов. Разработана ландшафтная карта, основанная на структурно-генетических принципах, внутри островного ландшафта выделены три географические местности. Предложена модель нуклеарной системы с ядром в виде кратера вулкана, по степени влияния вулкана на природные комплексы выделены три зоны. В составе парадинамических геосистем, связанных однонаправленными потоками вещества и энергии, выделены и проанализированы селевые и лавинные геосистемы. Количественно оценены вещественные потоки, генерируемые вулканом, лавинами и селями. Установлено, что в современный период именно вулкан является основным системообразующим фактором для большинства природных комплексов острова. Сделан вывод о том, что полиструктурность ландшафтного пространства отчетливо проявляется в пределах острова и связана с формированием на одной территории разных типов геосистем, выделение которых основано на разных физических принципах.

The concept of polystructurality of landscape space is discussed. The object of research is the island of Matua with an active volcano, lack of surface run-off and widespread development of debris-flow and avalanche complexes. A landscape map of the island's territory is presented, based on structural and genetic principles; three geographic areas are identified within the island landscape. A model of a nuclear system with a core in the form of a volcano crater has been developed; three zones have been identified according to the degree of the volcano's influence on natural complexes. Debris-flow and avalanche geosystems have been identified and analyzed as part of paradynamic geosystems connected by unidirectional flows of matter and energy. It has been established that in the modern period it is the volcano that is the main system-forming factor for most of the natural complexes of the island. It is concluded that the polystructural nature of the landscape space is clearly manifested within the island and is associated with the formation of different types of geosystems on the same territory, the identification of which is based on different physical principles.

Published: May 2021

В настоящее время как в России, так и за рубежом, уделяется повышенное внимание проблематике комплексного управления прибрежными зонами. Прибрежная зона – это ресурс, который подвергается практически ничем не ограниченному и бесконтрольному использованию и эксплуатации, что влечет за собой деградацию берегов и загрязнение природной среды. Ввиду недостаточной разработки понятийного аппарата в современном законодательстве и несовершенству самой законодательной базы, прибрежная зона как отдельный объект выбывает из правового регулирования, что неизбежно влечет за собой ее неэффективное использование. Поэтому одной из важных задач в подготовке магистров является овладение компетенциями в области управления прибрежными зонами.

Today much attention is paid to the problems of integrated management of coastal zones, both in Russia and abroad. The coastal zone is a resource that is subjected to almost unlimited and uncontrolled use and exploitation, which entails coastal degradation and environmental pollution. Due to the weak development of the conceptual apparatus in modern legislation and the imperfection of the legislative framework itself, the coastal zone as a separate object is removed from legal regulation, which inevitably entails its ineffective use. Therefore, one of the most important tasks in the preparation of the Master is to master the competencies in the field of coastal management.

A 100 Gbps True Full-Duplex Link with Interference Cancellation in the Background
Authors: Goyal Sandeep , Gupta Shalabh
Published: May 2021

In this work, we introduce the concept of true full-duplexing
(TFD) for high-speed interconnects. Full-duplex transceivers at
the two ends of an interconnect can support simultaneous
bidirectional data transfer. Full-duplexing can
help in increasing the throughput per lane and also enable higher
data transfer bandwidths without an increase in the routing
density. The proposed TFD approach allows for the use of
independent modulation schemes as well as independent baud-rates
by the transceivers on either side of the interconnect. The
approach also obviates the requirement of a dedicated start-up
protocol or a training sequence for
cancellation of near-end interference in the TFD transceivers. In
this work, we have used a correlation-based cancellation technique
which can support background cancellation of the interference.
Here, we demonstrate a 100 Gbps TFD link over a 1 m long coaxial
cable with off-the-shelf components, which is the first
demonstration of a full-duplex communication link at such a high
data rate.

Published: May 2021

In the frame of ongoing efforts between space agencies to define an on-off-keying-based optical low-Earth-orbit (LEO) direct-to-Earth (DTE) waveform, this paper offers an in-depth analysis of the Variable Data Rate (VDR) technique. VDR, in contrast to the currently adopted Constant Data Rate (CDR) approach, enables the optimization of the average throughput during a LEO pass over the optical ground station (OGS). The analysis addresses both critical link level aspects, such as receiver (time, frame, and amplitude) synchronization, as well as demonstrates the benefits stemming from employing VDR at system level. This was found to be around 100% compared to a CDR transmission approach.

ПОКАЗАТЕЛИ ИММУНИТЕТА У РОЖЕНИЦ С ТРОМБОФЛЕБИТОМ
Authors: Мусаева Я.В. , Долаева Т.М.
Published: May 2021

В данной статье изучены показатели иммунитета у родильниц с тромбофлебитом. Наиболее информативными лабораторными тестами являются толерантность плазмы к гепарину, фибринолитическая активность крови, гепариновое время. Ценным диагностическим методом, дополняющим биохимические исследования, является тромбоэластография. Преимуществами тромбоэластографического метода исследования являются высокая чувствительность и отсутствие соприкосновения исследуемой крови со смачиваемой поверхностью. Согласно полученным данным, у больных тромбофлебитом в острую стадию заболевания несколько повышаются уровни специфических противостафилококковых антител, лизоцима и С-реактивного белка. Эти изменения, по-видимому, связаны с определенным влиянием инфекции в качестве одного из факторов, приводящих к развитию тромбофлебита, и с наличием неспецифического воспалительного процесса. У женщин, у которых послеродовой период осложнился тромбофлебитом, существенно изменяются показатели коагулограммы. Изучение тромбоэластограмм показало, что у всех больных тромбофлебитом в остром периоде имеет место значительная гиперкоагуляция; укорачивается время свертывания крови, время образования сгустка, повышается максимальная амплитуда, наблюдаются тенденция к уменьшению специфической константы коагуляции и повышение индекса коагуляции. Проведенные исследования свидетельствуют о том, что у родильниц с тромбофлебитом наступают выраженные сдвиги в буферных системах как внеклеточной, так и внутриклеточной среды, протекающие по типу метаболического ацидоза. Эти изменения более выражены и наиболее продолжительны во внутриклеточной среде.

Puntaru beach is famous for its three-colored sand that is mixed into one of them reddish-brown, black, and white sand. Research on the mineral composition of the tricolor sand has been conducted so that the use of three-colored sand is still done traditionally. This study aims to obtain information on the silica content and other mineral compositions of the three-colored sand of Puntaru Beach as initial data for further development. The three-color sand preparation process is carried out by the method of milling / crushing sand samples then sieving and washing with H2O. Stages of characterization of silica in three-colored sand were carried out using X-ray fluorescence (XRF), X-ray powder diffraction (XRD), and Fourier-transform infrared (FTIR). The analysis showed that the percentage of Si was the most dominant 45.28%, followed by Fe 25.94% and other minor elements. XRD results show that the three-colored sand contains quartz mineral (SiO2) identified at the main peak with 2 with in the 24.34 ° area. The black color of the sand is influenced by Fe content of 25.94% with hematite metal oxide (Fe2O3) 15.80% and reddish-brown influenced by the presence of sulfur (3.25%) in the form of mineral SO3 4.32%.
On the Influence of Internal and External Factors on the Processes of Corrosion-Mechanical Fracture of High-Strength Low-Alloy Steels
Authors: N. N. Sergeev  , A. N. Sergeev  , S. N. Kutepov  , A. E. Gvozdev  , A. G. Kolmakov  , D. S. Klementyev
Published: May 2021

The article studies the influence of internal and external factors on the process of corrosion-mechanical fracture. It is shown that depending on the conditions of hydrogen charging (temperature and chemical composition of the corrosive medium, type of polarization), the mechanical properties of low-alloy steels change dramatically during the initial period of the experiment. With further increase in the holding time in a corrosive medium without polarization, there is no significant change in mechanical properties. It was found that an increase in the level of applied tensile stresses leads to a reduction in the incubation period of microcracks during hydrogen cracking. It was found that the sensitivity of low alloy steels to cracking is largely determined by the relaxation ability of the structure-the relaxation of residual peak micro-stresses localized at the grain boundaries and substructure boundaries reduces the sensitivity to corrosion-mechanical fracture.
A Method for Processing Top-k Continuous Query on Uncertain Data Stream in Sliding Window Model
Authors: Wahab Raja Azhan Syah Raja , Mohd Rum Siti Nurulain , Ibrahim Hamidah , Sidi Fatimah , Ishak Iskandar
Published: May 2021

The data stream is a series of data generated at sequential time from different sources. Processing such data is very important in many contemporary applications such as sensor networks, RFID technology, mobile computing and many more. The huge amount data generated and frequent changes in a short time makes the conventional processing methods insufficient. The Sliding Window Model (SWM) was introduced by Datar et. al to handle this problem. Avoiding multiple scans of the whole data sets, optimizing memory usage, and processing only the most recent tuple are the main challenges. The number of possible world instances grows exponentially in uncertain data and it is highly difficult to comprehend what it takes to meet Top-k query processing in the shortest amount of time. Following the generation of rules and the probability theory of this model, a framework was anticipated to sustain top-k processing algorithm over the SWM approach until the candidates expired. Based on the literature review study, none of the existing work have been made to tackle the issue arises from the top-k query processing of the possible world instance of the uncertain data streams within the SWM. The major issue resulted from these scenarios need to be addressed especially in the computation redundancy area that contributed to the increases of computational cost within the SWM. Therefore, the main objective of this research work is to propose the top-k query processing methods over uncertain data streams in SWM utilizing the score and the Possible World (PW) setting. In this study, a novel expiration and object indexing method is introduced to address the computational redundancy issues. We believed the proposed method can reduce computational costs and by managing insertion and exit policy on the right tuple candidates within a specified window frame. This research work will contribute to the area of computational query processing.

Published: May 2021

Network traffic monitoring is vital for enhancing the overall network performance and for optimizing the traffic flows. However, an emerging growth of use in cloud services, internet-of-things, block-chain and data analytics, demand the hardware-based-network-controller to provide more features for expanding network architecture. Therefore, Software Defined Networking (SDN) offers a new solution in terms of scalability, usability and programmable software-based-network-controller for the legacy network infrastructure. In fact, SDN provides a dynamic platform for the network traffic monitoring using international standard. In this study, SDN setup and installation method uses a Mininet emulator containing a controller Ryu with switching hub component, OpenFlow switches, and nodes. The number of nodes is adding until reaches to 16 nodes and evaluated through different network scenarios (single, linear and tree topology). Findings show that the single topology gives a winning criterion compared to other topologies. SDN implementation is measured with performance parameters such as Throughput, Jitter, Bandwidth and Round-Trip Time between scenarios using the Ryu controller. Future research explores on the performance of SDN in larger network and investigates the efficiency and effectiveness of SDN implementation in mesh topology.
Surface-enhanced Raman scattering of water in aqueous dispersions of silver nanoparticles
Authors: Filipczak Paulina , Hałagan Krzysztof , Ulański Jacek , Kozanecki Marcin
Published: May 2021

The resonance Raman effect (RRE) is a phenomenon which results in a strong selective enhancement of Raman signals from the samples. Previous studies showed that the RRE in liquid water directly corresponds to its supramolecular structure. It was also reported that the electric-field-induced orientation of water molecules on the electrode surface results in the surface-enhanced Raman scattering (SERS) effect. In this work, we show the SERS effect for water molecules in the dispersion of silver nanoparticles (AgNPs) without any external electrical field. An enhancement factor was estimated to be (4.8 ± 0.8) × 106 for an excitation wavelength of 514.5 nm and for AgNPs with an average size of 34 ± 14 nm. The temperature experiment results showed a higher enhancement with temperature increase. Performed simulation studies revealed a slowdown of the mobility of the water molecules close to the surface of AgNPs.

Bilgi ve iletişim teknolojilerinde yaşanan gelişmeler ve özellikle dijital ortamın veriye kolay erişme, veriyi depolama gibi imkânlar sunması ve daha da önemlisi “büyük veri” ile gerçekleştirilebilecekler göz önünde bulundurulduğunda geleneksel etik kodların dijital yaşamdaki etik gereksinimini karşılamak noktasında yetersiz kalacağı söylenebilir. Günümüzde yaşamın ve toplumsal kurumların neredeyse tümüyle dijital ortama kaymış olması ve “online hayat”ta karşılaşılan ortamlar dijital etik anlayışını zorunlu hâle getirmiştir. Dijital etik, maddi dünyadaki etik anlayışından farklı olarak insanın gündelik hayatının taşındığı dijital dünyadaki davranış ve yaşayış biçimlerine ahlaki bir çerçeve getirmeyi amaçlar. İnsanlar dijital platformlarda tıpkı maddi dünyada olduğu gibi çeşitli dijital eylemlerde bulunurlar. Dijital etik sayesinde, insanların yüz yüze iletişimde birbirlerine karşılıklı olarak saygı ve anlayış gösterdikleri gibi dijital dünyada da göstermeleri sağlanabilir. Bunun için sanal dünyada “dijital etiğin” sınırlarının belirlenmesi gerekmektedir.

TD 2629 - Democracia Digital e Pesquisa Empírica no Brasil: metodologias, instrumentos e abordagens do campo
Authors: Silva Sivaldo Pereira da
Published: May 2021

Nos últimos anos, as análises sobre a ideia de democracia digital vêm crescendo expressivamente, e atualmente esta área já constitui um campo com diversos estudos publicados. O objetivo deste texto é produzir um levantamento do atual estágio e das características da pesquisa empírica sobre democracia digital no Brasil, na forma de um estudo bibliométrico exploratório. Para isso, é traçado um quadro conceitual basilar sobre este conceito e, em seguida, é feito um mapeamento dos principais indicadores deste campo, baseado em amostra representativa de estudos empírico-metodológicos publicados em periódicos brasileiros indexados. A partir do recorte proposto, foi analisado um corpus de 73 artigos, publicados em 28 revistas científicas brasileiras, sendo aplicada, nesta amostragem, uma planilha composta por 22 variáveis que condensam os principais indicadores sobre os artigos. Os resultados reforçam a tendência à multidisciplinaridade deste campo, porém com protagonismo de áreas como comunicação, ciência política e administração. Também demonstraram que o volume de publicações está em linha ascendente, sendo marcado por estudos exploratórios ou descritivos. Plataformas ou sites governamentais e mídias sociais foram os objetos de análise mais frequentes. Apesar do caráter digital do fenômeno estudado neste campo, a coleta de dados ainda faz um uso incipiente de softwares ou scripts.
TD 2639 - Uma Análise do Financiamento Indireto do BNDES por Meio de Agentes Financeiros: o caso das empresas de engenharia e de construção no Brasil
Authors: Goes Fernanda Lira , Vilela Rodrigo de Oliveira
Published: May 2021

O objetivo deste texto conflui em analisar o acesso à política de apoio financeiro oferecido pelo Banco Nacional de Desenvolvimento Econômico e Social (BNDES) às corporações da área de engenharia e construção em atuação nacional. O BNDES apoia empresas com o financiamento no modo de operações diretas, com solicitações realizadas ao banco, e no modo indireto, com acesso ao apoio por meio de agentes financeiros, como demais bancos privados, públicos ou de economia mista. A metodologia escolhida optou por analisar as empresas clientes do financiamento do BNDES para obras e serviços no exterior: Andrade Gutierrez, Camargo Corrêa, Confab, Contracta, EMSA, Mello Junior, OAS, Odebrecht, Pro Sinalização, Queiroz Galvão e Schahin. O período em questão foi a qualquer tempo desde 1998, ano base do desenho da política nestes moldes.
TD 2640 - Tendências Regionais da Indústria Brasileira no Século XXI
Authors: Diniz Clélio Campolina , Mendes Philipe Scherrer
Published: May 2021

O objetivo deste trabalho é atualizar o diagnóstico sobre as tendências recentes do padrão locacional da indústria no território. Considerando-se a retomada do crescimento econômico e industrial no século XXI, as mudanças estruturais em curso e seus efeitos nos processos de industrialização, desindustrialização e padrão locacional da indústria, torna-se necessário uma reavaliação dos resultados recentes e suas tendências, especialmente seus impactos regionais. Entre essas mudanças estruturais, destacam-se as transformações no cenário internacional; o acelerado processo de mudanças tecnológicas e organizacionais; o aumento do peso dos serviços na ocupação e na renda; o dinamismo da fronteira agropecuária; as mudanças nas políticas públicas; os investimentos em infraestrutura, principalmente relacionados ao setor energético; e a adoção de políticas sociais de natureza horizontal. Tudo isso diante de um grave processo de desindustrialização do país.
TD 2643 -Variações na Renda Real não Captadas pelo PIB: decomposição em efeito termos de troca e efeito preços relativos entre comerciáveis e não comerciáveis – Brasil (1948-2018)
Authors: Bastos Estêvão Kopschitz Xavier , Araujo Beatriz Cordeiro
Published: May 2021

Os ganhos (ou perdas) reais de renda decorrentes de variações nos termos de troca e nos preços relativos entre bens comerciáveis e não comerciáveis, denominados “ganhos de comércio”, não são contabilizados na variação real do produto interno bruto (PIB). O agregado cuja variação computa esses ganhos é a renda interna bruta real (RIBR), cujo cálculo consta nas recomendações internacionais do System of National Accounts 2008 (SNA, 2008), mas não é realizado para o Brasil pelo Instituto Brasileiro de Geografia e Estatística (IBGE). Neste trabalho, é feita a extensão, aperfeiçoamento e atualização desse cálculo para o período 1948-2018, incluindo a separação entre os efeitos termos de troca e preços relativos, presente na literatura internacional, mas não constante do SNA 2008. A diferença entre RIBR e PIB real (PIBR) é relevante para países com grande abertura comercial e, mesmo para países menos abertos, em períodos de grandes variações nos termos de troca e preços relativos, como ocorre em alguns períodos para o Brasil.
TD 2644 - Investidores Institucionais e o Financiamento da Infraestrutura – uma estimativa do volume de recurso em potencial para o Brasil
Authors: Rocha Katia
Published: May 2021

Este estudo tem como objetivo quantificar o volume de recursos em potencial de investidores institucionais – fundos de pensão, seguradoras, fundos de investimento e fundos soberanos – do mercado global (Organização para a Cooperação e Desenvolvimento Econômico – OCDE) e doméstico para infraestrutura no Brasil. Investidores institucionais não são homogêneos entre si e possuem ampla gama de objetivos, características e fatores estruturais que influenciam seu investimento, além de restrições regulatórias. As variáveis críticas para o modelo envolvem: i) estimação dos ativos sob gestão dos institucionais considerando restrições estruturais de liquidez, tamanho e perfil por tipo de investidor, o que reduz em pelo menos 50% o volume inicial dos ativos; ii) expectativa de aumento de 2% a 3% na alocação para a classe de ativos de infraestrutura na carteira dos institucionais na próxima década; iii) dinâmica de crescimento dos ativos sob gestão de 6% ao ano (a.a.) conforme dados históricos; e iv) estimativa de 2.5% do market share do Brasil no volume potencial de recursos globais para infraestrutura. O volume de recurso em potencial estimado para o Brasil situa-se entre US$ 9 bilhões e US$ 17 bilhões anuais na próxima década, equivalente ao valor entre 0,5% e 0,9% do produto interno bruto (PIB) de 2019. No melhor cenário, mantendo-se os níveis atuais de investimento em infraestrutura de cerca 2% do PIB, o fluxo potencial de institucionais elevaria o nível anual de investimento para cerca 3% do PIB, valor considerável, porém ainda aquém da meta estimada de 4% do PIB (cerca de US$ 70 bilhões por ano). Os resultados estão em linha com estimações de trabalhos semelhantes para os emergentes, o que demonstra certa robustez. Ressaltamos que o exercício de estimação fornece valores que se justificam apenas como estimativa de ordem de grandeza devendo ser visto com parcimônia e de acordo com as hipóteses consideradas.
TD 2652 -Evolução Regional do Mercado de Trabalho no Brasil (2000-2018): apontamentos para a Política Nacional de Desenvolvimento Regional (PNDR)
Authors: Macedo Fernando Cézar de , Porto Leonardo Rodrigues
Published: May 2021

Este estudo tem como objetivo analisar a evolução do emprego no país, tomando como referenciais os períodos 2000-2014 e 2015-2018. Trata-se da situação atual e da evolução do emprego formal no Brasil, por meio de uma análise regional e multiescalar, conforme os princípios básicos preconizados pela Política Nacional de Desenvolvimento Regional (PNDR). Deste modo, busca-se analisar o desempenho do mercado de trabalho brasileiro em diferentes recortes espaciais, tais como as macrorregiões e/ou por hierarquia urbana, além de efetuar uma análise setorial regionalizada. Nada obstante, sua ênfase principal recai sobre o nível das microrregiões (MRGs) geográficas do Instituto Brasileiro de Geografia e Estatística (IBGE), com atenção especial à tipologia sub-regional da PNDR, cujos parâmetros foram atualizados por Macedo e Porto (2018). Este texto discute as principais determinações que atuaram sobre a dinâmica regional brasileira e seu mercado de trabalho nos períodos em análise. Na segunda seção, analisa-se o movimento da economia brasileira em sua dimensão macroeconômica e em seus rebatimentos regionais. Busca-se avaliar, sempre que possível, seus impactos sobre o mercado de trabalho. Nas terceira e quarta seções, analisa-se o mercado de trabalho em diferentes níveis de agregação regional. Na terceira seção, traça-se um quadro dos indicadores do mercado de trabalho para as MRGs brasileiras com base nos dados dos censos demográficos do IBGE, para os anos de 2000 e 2010, e toma como referência a tipologia da PNDR. Na quarta seção, faz-se uma análise da evolução do emprego formal no Brasil, de 2002 a 2014 e de 2015 a 2018. Nesta parte, consideraram-se as macrorregiões, microrregiões e a posição dos centros urbanos na hierarquia urbano-regional, definida pela pesquisa Regiões de Influência das Cidades (Regic).
RISK-RETURN PERFORMANCES OF REAL ESTATE INVESTMENT FUNDS IN TURKEY INCLUDING THE COVID-19 PERIOD
Authors: Çamlibel Mehmet Emre , Sümer Levent , Hepşen Ali
Published: May 2021

The purpose of this research is to give an insight into the Turkish real estate investment funds (T-REIFs) by comparing their risk-return performances with the main benchmark investment tool Istanbul Stock Exchange-100 (BIST-100) Index. This study evaluated the performance of T-REIFs in four different periods between January 2017 and December 2020 (2017m1–2017m12, 2018m1–2018m12, 2019m1–2019m12 and 2020m1–2020m12) including the Coronavirus Disease (Covid-19) period by applying the Sharpe and Treynor ratios. In a well-diversified portfolio both ratios give the same results, but in the presence of non-systematic risk and the portfolio is poorly diversified, the Treynor ratio is a better indicator than the Sharpe ratio. The findings of this study show that rankings of Sharpe and Treynor ratios may differ for each period. These results also support the fact that the portfolios of funds in the Turkish real estate market are not well diversified. By providing corporate tax exemptions, and by enabling the investors to diversify their investments and reduce their risks, real estate investment funds are important alternatives to direct real estate investments in Turkey. In that context, being one of the pioneer studies in this niche and a new topic in emerging markets, analyzing the return performances of T-REIFs and comparing them with the returns of the BIST-100 index is aimed to contribute to literature as well as provide insight to investors who may consider investing in the Turkish real estate capital market instruments.
FACILITATING PARTICIPATORY ADVANCEMENT IN ARCHITECTURE USING EXTENDED REALITY SOLUTIONS. THE LITERATURE ANALYSIS
Authors: Misius Vladas
Published: May 2021

Public engagement and participatory advancement in architecture have entered a new level, as public expectations rise and technological innovations create new opportunities. Stakeholders can contribute to architecture through variety of new technological tools that evolved significantly over the last decade and the key question is how to make architecture better by using them. The paper presents findings of the initial stage of research – exploratory literature analysis of emerging trends for adopting virtual reality (VR), augmented reality (AR), mixed reality (MR) and other human–computer interactions in urban design and architecture. The goal is to figure out the most recent trends of how public can participate and improve the quality of architecture through modern technologies. The results show that directions of current investigations on participatory advancement in architecture by using extended reality (XR) solutions develop in these main directions: easy to use tools, simulation of space and content, evaluation of results, continuous participation of stakeholders and adoption of XR solutions in architectural design, urban design and landscape architecture.
Alignment of Irregular Grains by Radiative Torques: Efficiency Study
Authors: Herranen Joonas , Lazarian A. , Hoang Thiem
Published: May 2021

We study the efficiency of grain alignment by radiative torques (RATs) for an ensemble of irregular grains. The grains are modeled as ensembles of oblate and prolate spheroids, deformed as Gaussian random ellipsoids, and their scattering interactions are solved using numerically exact methods. We define the fraction of the grains that both rotate fast and demonstrate perfect alignment with grain long axes perpendicular to the magnetic field. We quantify a factor related to the efficacy of alignment and show that it is related to a

factor of the analytical model of the RAT theory. For the interstellar radiation field, our results indicate that the degree of RAT alignment can reach ∼0.5, which may be sufficient to explain observations even if grains do not have magnetic inclusions.
