Authors: Putera Bagas Dwi , Ali Erfansyah , Wijanto Heroe , Ramdhani M.
Published: January 2019

Synthetic Aperture Radar (SAR) is a radar system that uses platform movement combined with signal processing. Eventhough it use a small antenna, SAR produce high resolution as good as a large antenna. In SAR imaging, radar is mounted on a moving platform. It transmits electromagnetic pulses and receives backscattered echo signals. Transmitted pulses are subsequently scattered by earth surface and only small portion of them are received by antenna. SAR transmitted signals normally is a chirp or linear frequency modulation (LFM) signal. Chirp signal can be generated by using the analog and digital generator. Digital chirp generator is divided into two methods which are the memory-based and direct digital synthesizer (DDS). The difference of these two methods is located in the memory ROM. In this study, we designed and realized digital chirp generator by using Field Programmable Gate Array (FPGA) DE-1 development board for SAR implementation. It operates in 1.27 GHz (L Band) frequency and had a bandwith of 10 MHz with 24 MHz sampling rate. We found that the output of FPGA is well performed for chirp signal in digital domain.

Published: January 2019

Emission generated by motor vehicles is one of the environmental pollution and it can interfere with the health, especially on the 2-stroke engine in which the emissions are greater than the 4-stroke engine. In this study, HHO, generated by electrolysis process in a reactor, was injected into 2-stroke engine. A test method called "idle" was performed using SNI 19-7118.3-2005 standard so that the emissions generated on the 2-stroke engine was reduced. HHO was added by forwarding the gas through the hose on bubbler and entering the air hose filter in the carburator. The reactors were conditioned to produce 400 ml electrolysis and a catalyst such as KOH with different concentrations. It affected the rate of HHO flow. Prior to the addition of HHO, levels of HC was 6453 ppm at 6000 rpm and it decreased by 31.66% when the HHO was added. This decrease also occurred in CO, where the levels of CO fell from 2. 56% to 1.75 %. On the other hand CO2 levels increased from 2.23 % to 4.22 % with the HHO addition. In this study, it was found that the best HHO rate was147 mLpm. Besides, at 6000 rpm, the engine efficiency increases 5.1 % when 147 mLpm HHO was added.

The main trends in the renewal movement of Russian Buddhism at the beginning of the XX century .
Authors: Nesterkin Sergei
Published: January 2019

The object of the study is the renovationist movement in Russian Buddhism. At the beginning of the XX century, some part of the Buddhist community began the process of revising the organizational forms of its existence, revising its theoretical and practical baggage. The work focuses on defining the basic principles of the main directions of this movement, studying their goals and objectives and identifying differences in their approaches to reforming the Buddhist church in the context of the ongoing changes in the socio-political conditions of Russia at the beginning of the 20th century. As a result of the analysis of documents and archival materials, the author investigated the doctrinal and ideological foundations of the movements and their organizational forms. The study found that there were two significantly different movements that set themselves very different tasks and used fundamentally different approaches to solve them. On the one hand, the activities of Buryat enlighteners B. Baradin, Ts.Zhamsarano, etc., and such representatives of the clergy as A. Dorzhiev, Ch. Iroltuev, GanzhurovaвЂ“Gegen were designed to develop an ideological basis for preserving the national identity of the Buddhist peoples of Russia in the conditions of ideological and political expansion. On the other hand, L.S. Tsydenov and his followers set themselves a significantly different task: to reform Buddhism in such a way that it could develop in a new socioвЂ“cultural environment, in the Western culture of Russia. The task here was not so much the preservation of national identity as the development of the Buddhist tradition in a new cultural space, which indirectly solved the first task.
Assessment of Financial Conditions of South African Municipalities: A Unique Model for KwaZulu-Natal
Authors: Kleynhans Ewert P.J. , Coetzee Clive
Published: January 2019

Most South African municipalities experience significant financial problems. This study investigates the financial conditions of municipalities in the province of KwaZulu-Natal (KZN). It was found that the most important factors which influence their financial position are unobservable municipally unique factors. The ratio of people of non-working age to the total population is also significant in influencing the financial position of municipalities. This article designed a unique financial conditions measurement framework to evaluate the financial status of local governments. Two independent instruments were developed, first to measure the financial quality of a municipality, and secondly, to identify and examine a number of socio-economic factors possibly affecting the financial condition of these municipalities. The study developed a composite financial condition index (CFCI) and a financial conditions management index (FCMI), and then tested the framework on 51 municipalities in the KZN province from 2009 to 2015. The study used a panel data approach with two financial condition indices as indicators. The findings suggest that, in the absence of individual effects, most of the selected socio-economic variables are relevant in terms of explaining some of the variations in municipal financial conditions. Cross-section fixed-effects do, however, significantly improve the overall performance of the model, suggesting that it is rather the unobservable municipally unique factors affecting municipal financial conditions.Â

Combined antihypertensive therapy in the light of modern recommendations: strategy of one tablet
Authors: Morozova T E
Published: January 2019

The review focuses on the main strategies of antihypertensive therapy set out in the 2018 ESC/ESH recommendations. The basis of antihypertensive therapy consists of five main classes of antihypertensive drugs, which should form the basis of the combined drug antihypertensive therapy in most patients. The single pill strategy is to take advantage of fixed combinations as a starting antihypertensive therapy for most patients. Among the fixed combinations, the combination of an ACE inhibitor with a diuretic (Noliprel®) remains one of the most preferred for antihypertensive therapy, since In addition to its antihypertensive potential, it has the ability to prevent renal, coronary complications and cerebrovascular events, to influence the progression of atherosclerosis, the occurrence of new cases of diabetes and to achieve a statistically significant reduction in total mortality

A junction coverage compatibility score to quantify the reliability of transcript abundance estimates and annotation catalogs
Authors: Soneson Charlotte , Love Michael I , Patro Rob , Hussain Shobbir , Malhotra Dheeraj , Robinson Mark D
Published: January 2019

Most methods for statistical analysis of RNA-seq data take a matrix of abundance estimates for some type of genomic features as their input, and consequently the quality of any obtained results is directly dependent on the quality of these abundances. Here, we present the junction coverage compatibility score, which provides a way to evaluate the reliability of transcript-level abundance estimates and the accuracy of transcript annotation catalogs. It works by comparing the observed number of reads spanning each annotated splice junction in a genomic region to the predicted number of junction-spanning reads, inferred from the estimated transcript abundances and the genomic coordinates of the corresponding annotated transcripts. We show that although most genes show good agreement between the observed and predicted junction coverages, there is a small set of genes that do not. Genes with poor agreement are found regardless of the method used to estimate transcript abundances, and the corresponding transcript abundances should be treated with care in any downstream analyses.

Authors: Sampaio Caroline Castilhano , Emiliozzi Caroline Zeppellini Santos , Furnari Laura
Published: January 2019

A técnica de irradiação de corpo inteiro (TBI) é considerada uma técnica de alta a complexidade em radioterapia já que exige campos alargados. Os esquemas de cálculo para fazer a determinação exata da distribuição da dose no TBI são complexos e variações na posição do paciente alteram dramaticamente as distribuições de dose. Sendo assim é desejável ter uma técnica de medição in vivo disponível. Os diodos semicondutores são robustos, relativamente baratos e fornecem leituras on-line para inferência imediata de dose o que é uma grande vantagem em comparação com o processo de reaquecimento prolongado requerido para um dosímetro termoluminescente (TLD). O objetivo deste trabalho é a caracterização e validação do diodo semicondutor (T600010L PTW) para utilização em medidas in vivo, e em tempo real, da dose liberada em um tratamento de irradiação de corpo inteiro. Os dosímetros devem ser caracterizados e calibrados para sua utilização na técnica em questão. Sendo assim foi feito o estudo da reprodutibilidade, da linearidade e da dependência da resposta dos diodos com a taxa de dose, com a distância fonte-detector (SSD) e com o ângulo de incidência do feixe de radiação. A calibração dos diversos diodos foi realizada por intercomparação com uma câmara de ionização Farmer e sua verificação foi feita com a simulação de um tratamento em um phantom antropomórfico RANDO®. Uma vez que o dosímetro mostrou-se adequado e com variações menores que 1%, estabeleceram-se limites de ação para dosimetria in vivo de acordo com a região a ser tratada e levando em conta fatores de incertezas que não são intrínsecos ao detector. O valor máximo encontrado para o limite de ação foi de 9,6% na região do joelho.

O controle de qualidade dos receptores de imagens radiográficas é fundamental para a garantia da qualidade do exame. Nos sistemas digitais, os parâmetros de avaliação e procedimentos de controle de qualidade ainda não estão bem definidos em âmbito nacional. Neste trabalho foi aplicado o “Protocolo Espanhol de Controle de Qualidade em Radiodiagnóstico” na avaliação de detectores de radiologia digital. Foram realizados testes de ruído de fundo do detector, permanência da imagem anterior, uniformidade da imagem e razão sinal-ruído, função resposta do detector, verificação do indicador de dose, ruído, resolução espacial, limiar de sensibilidade de detalhe-contraste e verificação dos elementos defeituosos do detector. Os testes de desempenho foram aplicados periodicamente em cada detector analisado. Em geral, os resultados obtidos indicaram desempenho satisfatório dos detectores analisados e ainda foi possível estabelecer valores de referência para avaliações ao longo do tempo. O Protocolo Espanhol mostrou-se uma boa referência para a elaboração de um padrão nacional de avaliação destes equipamentos.

O melanoma é considerado o mais perigoso dos cânceres de pele, isso porque ele apresenta alta taxa de metástase e o maior índice de mortalidade por tumores cutâneos.  Uma forma de reduzir esse índice seria o diagnóstico precoce do tumor. Imagens térmicas associadas a modelos matemáticos térmicos da pele têm-se mostrados muito eficazes no diagnóstico de melanomas, isso porque juntamente com a lesão surgem vasos sanguíneos, o que provoca um aumento da temperatura no local. No presente trabalho são apresentados resultados de simulações numéricas do comportamento térmico da pele por meio do modelo Dual Phase Lag (DPL).  A solução numérica do modelo foi obtida por meio do método de diferenças finitas utilizando um esquema implícito. Os resultados obtidos numericamente foram comparados com soluções analíticas e numéricas disponíveis na literatura, obtendo-se excelente concordância entre as soluções. Os parâmetros do modelo DPL foram também explorados para obter a solução numérica do modelo Single Phase Lag (SPL) e do modelo clássico de Pennes, estes três modelos foram avaliados quanto à qualidade de previsão para um caso real clínico para a situação em que a pele apresenta uma região não sadia pela presença de um melanoma.

Um material considerado simulador de tecido humano deve apresentar um comportamento de absorção da radiação, em função da espessura, muito semelhante ao do material de referência. Por sua abundância no corpo humano, a água é muitas vezes utilizada como material de referência. Neste trabalho, foram determinadas propriedades de atenuação de quatro conjuntos de amostras, preparadas a partir de um  modelo matemático previamente desenvolvido, utilizando um equipamento de Tomografia Computadorizada de Dupla Energia (DECT, em inglês). Foram obtidos os coeficientes mássicos para os quatro conjuntos de amostras calculados a partir dos números CT médios das imagens e da energia efetiva associada a cada tensão aplicada (80, 100, 120 e 140 kV) ao tubo de raios X. Os coeficientes mássicos do conjunto de amostras calculados são semelhantes, nas energias efetivas estudadas, ao da água e ao previsto pelo modelo matemático, apresentando respectivamente, 1 a 2 % e 4 a 7 % de diferença percentual relativa.

O método de espectrometria Compton apresenta-se como uma técnica eficiente para medição de espectros de feixes de fótons de energia alta que são produzidos em aceleradores lineares clínicos e unidades de radioterapia de Co-60, usadas em tratamento de pacientes com câncer. Neste trabalho foi feita a caracterização de um espectrômetro Compton com o objetivo de medir o espectro de altura de pulsos (PHS, do inglês Pulse Height Spectra) para uma unidade de Co-60 de uso clinico, com a finalidade de obter o espectro de fluência de fótons para posteriormente aplicar este método na medição e reconstrução do espectro de bremsstrahlung de um acelerador linear clínico. Previamente foi feita a caracterização de um detector de NaI(Tl), obtendo as funções de resposta em energia para o espectrômetro Compton. Aqui apresentamos a medição dos espectros de altura de pulsos em configuração Compton para energias de raios X de 70 a 100 kV com ângulo Compton de 90o, as quais foram feitas com o fim de obter a resposta do espectrômetro a estas energias, para depois disso medir o espectro de altura de pulsos para a unidade de Co-60 em diferentes ângulos Compton.
A ASSISTÊNCIA E O ESTADO DE BEM ESTAR SOCIAL NO BRASIL
Authors: Ramos Duarte Ana Beatriz Borges
Published: January 2019

As políticas de assistência enquanto políticas sociais estão associadas ao desenvolvimento do Estado do Bem Estar Social. Tradicionalmente, as associações religiosas desenvolveram, no Brasil, trabalhos sociais voluntários filantrópicos e sem fins lucrativos em parceria com o Estado, que até o século XX não havia oficializado ainda a Assistência como política pública. A Constituição de 1988 significou um marco para as políticas de Assistência, introduzindo uma reforma no sistema de seguridade social, caracterizado, sobretudo, pela descentralização político-administrativa das políticas públicas. Os maiores problemas relacionados à ineficiência das políticas de assistência no Brasil atualmente estão relacionados a dificuldades nos processos de descentralização da assistência e participação da sociedade civil nas decisões acerca das políticas públicas.

The paper argues that franchising is a specific form of doing business that applies to all developed market-economy countries. However, the scope of franchise practice in the Ukrainian economy, in particular in the area of doing business and entrepreneurship among socially vulnerable groups, remains rather limited. The research hypothesis is to assess the attractiveness of franchising for socially vulnerable populations. The implementation of this type of entrepreneurship by socially vulnerable groups allows to gain significant benefits for all the participants of franchising relationships: for start-uppers this is a good opportunity for effective self-employment, since they obtain a stable profitable business; for reputed firms and companies – to expand and strengthen their market positions; for the state – to acquire an effective tool to support entrepreneurship. The purpose of this study is to provide rationale for selecting the most appropriate franchise business model for socially vulnerable populations and to evaluate its implementation specifics. To summarize the research findings, the following methods were used: the taxonomy method – to analyze the key stages of business models evolution and classification; cluster and factor analysis – to expound the basic elements and tools of a franchise business model; the methodology for modeling of future by constructing scenarios – to predict possible socio-cultural and existential franchise-based entrepreneurship risks. The paper also seeks to explore characteristics of franchise entrepreneurship; its significance and role in the socioeconomic framework; the sources and motifs behind social entrepreneurship; the specific patterns of building business models for socially vulnerable groups along with justifying the particular indicators and criteria to develop a franchise business model typology and to reveal the institutional aspects in the formation of different types of franchise-based business models. The above study on the conceptual paradigm of social entrepreneurship has allowed to expand the theoretical understanding of social business entities functioning and development and to identify the peculiarities in the formation of different types of franchise business models. The application of the most optimal model will contribute to enhance the management efficiency of social businesses, which in turn will increase the cumulative social effects through the replication and dissemination of successful sustainable business models.

The paper discusses various approaches to the interpretation of a ‘cluster’ concept along with revealing basic characteristics of clusters provided by domestic and foreign scholars. An emphasis is made on increasing interest of a range of economic experts and professionals to local industrial agglomeration and specialization issues. However, among the vast body of ideas and concepts, the most relevant is the cluster approach that has been successfully implemented around the globe, since it allows to take full advantage of regional potential taking into consideration both public and private interests. The cluster approach as a tool of local industrial agglomeration and specialization contributes to the increase of competitiveness and innovation capacity. The main focus is drawn to the stages of regional space clustering and the sequence control of the territory cluster development. It is proved that successful implementation of cluster policy should be based on internal processes with due regard to the effects of the external environment. In addition, the government can enhance cluster development by changing local demand; public procurement in territorial companies; training of local workforce through the implementation of supplementary education programs and retraining of personnel; promoting region’s branding to attract foreign investment. It is argued that the cluster approach will facilitate a comprehensive methodology to address the issues of enterprise interactions within different industries. An algorithm of regional space clustering and cluster development management has been elaborated. Argument is given towards the importance of building and implementation of a cluster policy as a framework for each region effective development. The research findings reveal that the success in cluster development can be achieved by creating a well developed cluster policy that has to be a joint responsibility of business and respective government authorities.

This paper discusses the challenging issues of economic transformation processes and the government integration into the system of international labour division in the context of enhancing the competitiveness of national manufacturers. The multidimensional character of the above agenda in terms of increasing competition, instability of social and political factors, structural transformation of the global industrial system, the internationalization of business activities, etc. complicates the process of managerial decision-making and nudges companies to search for new methods of combining their efforts and capacities and enhance cooperation to survive or to gain market leadership. The research findings suggest that cluster-based cooperation of enterprises triggers a range of multiple effects, i. e. strategic, synergistic, innovative, economic, etc. These effects occur at different levels – the level of a certain unit, project, business entity, cluster or the national economy overall. To evaluate the impact of joint cluster-based activity of enterprises it is critical to take into consideration the following factors: long-term development factors consistency, redistribution of risks between partners, exchange of specific assets, production strategy balance and coordination, consolidation of financial assets. It is argued that the efficiency analysis should rely on the comparison of various characteristics of the two variants of participating companies’ development: they enjoy either full autonomy or act within the partnership framework. To study the practice of domestic integrated structures it is important to account for the financial recovery capacity of partners as well as their social efficiency components, to differentiate the planning horizon, focus on specific assets, i. e. the elements of potential synergy.

The paper seeks to provide a comparative analysis of the categories of ‘entrepreneurship’,’motivation’ and ‘encouragement’ based on research studies by Ukrainian scholars. It is argued that entrepreneurship and small and medium-sized business in particular, in the context of market transformations in Ukraine should become a critical factor in boosting socioeconomic development of the country. Extensive study of a vast body of statistical data and domestic research findings has revealed the specifics and trends of doing business in modern Ukraine. The paper also discusses and provides deeper insights into the basic aspects of shadow economy in Ukraine which hinders the development of the national economy competitiveness, growth of social living standards as well threatens Ukraine’s further integration into economic space of developed European countries. The current state of the shadow economy in Ukraine has been tracked along with revealing the essential factors driving the national shadow economy and suggesting a set of relevant consistent actions to combat this negative phenomenon. The paper also describes the key methods of employee encouragement and motivation at domestic enterprises together with providing the monitoring results on the common leadership and management mistakes that occur in the process of staff motivation in the national business settings. Based on the authors’ diverse personal experience of working in different domestic companies, an individual scheme of staff motivation is proposed which can harmonize the common objectives of the employer and the employee, thus contributing to enhance the competitiveness of domestic enterprises. In the frameworks the given conceptual analysis of specific characteristics of doing business in modern Ukrainian realia and shadow economy effects, a methodology and principles of personnel motivation are suggested which facilitate an increase in labour productivity and boost employees’ personal interest in their due diligence and effective performance.
