Teachers Access to a Brazilian Virtual Learning Community Over Time: Why They do Not Come Back
Authors: Luz Mauricio Pinto da
Published: January 2020

A virtual learning community, created in association with courses offered within an online professional development program for Brazilian biology teachers, was reviewed over a two-year period. This virtual learning community is designed to be moderated and managed solely by the teachers themselves without any guidance. The results showed a recurring participation pattern, expressed by a large number of page and message views, for short periods of time during the courses, followed by a sharp drop in those views after the courses closed. This pattern was unrelated to course subject or duration. The questionnaires revealed that teachers who did or did not access the virtual community after the end of their courses were indistinguishable from their demographic profiles or digital skills. The analysis of teachers responses to the questionnaire showed that the lack of time due to work overload was the main reason why teachers abandoned the virtual learning community, regardless of highly positive user evaluations. The implications of the results for the future implementation of virtual learning communities in developing countries are discussed.

Dziecko obcojęzyczne w polskim przedszkolu, czyli o (nie)ograniczeniach w edukacji
Authors: Bączyk-Lesiuk Klaudia
Published: January 2020

Od kilku lat widać w Polsce rosnącą liczbę cudzoziemców. Co ciekawe, do naszego kraju przybywają już nie tylko pracownicy sezonowi, ale jak wynika z badań Eurostatu, osoby decydujące się na stały pobyt, kupujące mieszkania, zakładające rodziny. W kontekście globalizacji kultury warto zatem zastanowić się nad stanem polskiej edukacji, ze szczególnym uwzględnieniem edukacji przedszkolnej. Co państwo może zaoferować dzieciom uczącym się języka polskiego jako obcego/drugiego? Jak w tej nowej sytuacji edukacyjnej odnajdują się nauczyciele? Kim tak naprawdę staje się osoba pracująca w przedszkolu: nauczycielem, mentorem, strażnikiem tożsamości, logopedą, psychologiem czy po prostu towarzyszem? Praca koncentruje się wokół problemów zgłaszanych przez nauczycieli w następstwie kontaktu z uczniem imigracyjnym w przedszkolu. Przedstawione studia przypadków staną się asumptem do pytania o potrzebę zmian w obliczu wyzwań ponowoczesnej Europy.

Authors: K. Prajapati Virendra , Priya Harsh , Sharma Anuj
Published: January 2020

Context: The unique position, shape and structure of the lower jaw lead to its high incidence of fracture. The mandible is a membranous long bone bent to a horse shoe shape. Even though it is very strong, its prominent position on the face makes it vulnerable to fracture. The fracture can occur in different parts of the bone, sometimes at multiple sites too, depending upon the nature of the impact. Aim and Setting and Design: The purpose of this study is to determine the etiology, pattern and distribution of mandibular fractures in a Government Medical College at Ranchi, Jharkhand. Methods and Materials: The study was carried out in the dental OPD of a Government Medical College at Ranchi, Jharkhand from June 2013 to November 2014. All patients who were clinically and radio graphically confirmed fracture mandible were examined and all demographic variables (age, gender, place, education, occupation, tobacco habit and duration of habit) were recorded. The pattern and cause of mandibular fracture were included and sites were classified accordingly as ramus, condyle, symphysis, body, parasymphysis and angle. Statistical Analysis: Simple descriptive statistics were employed for the analysis. Results and Conclusion: The present study concluded Road Traffic Accidents as the most common cause for mandibular fractures. Also, parasymphyseal fracture was the commonest unilateral and parasymphysis and condyle as commonest combined fracture of the mandible..

Authors: Strokovskaya L , Ziemnicka J , Michalik J
Published: January 2020

Viral genome DNA from four different multiple-enveloped nuclear polyhedrosis virus isolates, obtained from naturally infected larvae of satin moth (Stilpnotia salicis), a pest of poplar tree (Populus) was analysed. Larvae were collected over a period of 11 years, from 1978 to 1989. The genomic DNA restriction patterns pointed to heterogeneity of these wild-type viruses. The differences observed in isolates of several years revealed limited restriction fragment length polymorphism and showed that these viruses contained distinct, but closely related genotypes. The genome size of SsMNPV was established as 128-134 kb, based on HindIII and SacI restriction analysis.

Squash inhibitor family of serine proteinases.
Authors: Otlewski J , Krowarsch D
Published: January 2020

Squash inhibitors of serine proteinases form an uniform family of small proteins. They are built of 27-33 amino-acid residues and cross-linked with three disulfide bridges. The reactive site peptide bond (P1-P1') is between residue 5 (Lys, Arg or Leu) and 6 (always Ile). High resolution X-ray structures are available for two squash inhibitors complexed with trypsin. NMR solution structures have also been determined for free inhibitors. The major structural motif is a distorted, triple-stranded antiparallel beta-sheet. A similar folding motif has been recently found in a number of proteins, including: conotoxins from fish-hunting snails, carboxypeptidase inhibitor from potato, kalata B1 polypeptide, and in some growth factors (e.g. nerve growth factor, transforming growth factor beta 2, platelet-derived growth factor). Squash inhibitors are highly stable and rigid proteins. They inhibit a number of serine proteinases: trypsin, plasmin, kallikrein, blood clotting factors: Xa and XIIa, cathepsin G. The inhibition spectrum can be much broadened if specific amino-acid substitutions are introduced, especially at residues which contact proteinase. Squash inhibitors inhibit proteinases via the standard mechanism. According to the mechanism, inhibitors are substrates which exibit at neutral pH a high kcat/K(m) index for hydrolysis and resynthesis of the reactive site, and a low value of the hydrolysis constant.
Serine proteinase inhibitors from insect hemolymph.
Authors: Polanowski A , Wilusz T
Published: January 2020

Insect hemolymph, like vertebrate serum, contains several different types of polypeptides that are able to inhibit the catalytic function of proteolytic enzymes, however studies on proteins possessing this capability have been limited to a relatively few species. A comparative examination of the inhibition of trypsin, chymotrypsin, neutrophil elastase and cathepsin G and pancreatic elastase by the hemolymph of 14 insect species belonging to six orders showed great diversity in terms of both total proteinase inhibitory capacity and specificity. Most of the inhibitors examined fall into two groups: low molecular mass proteins (below 10 kDa) related to Kunitz type inhibitors, and proteins of about 45 kDa which belong to the serpin superfamily of serine proteinase inhibitors. This minireview describes the properties, characteristics and possible biological significance of selected inhibitors.
Computer modelling of human alpha 1-antitrypsin reactive site loop behaviour under mild conditions.
Authors: Kołoczek H , Jezierski G , Pasenkiewicz-Gierula M
Published: January 2020

Human alpha 1-antitrypsin (alpha 1-PI) is a member of the serpin superfamily of proteins. The reactive site loop (RSL) of the serpin binds to the active site of its target proteinase. Deficiency of alpha 1-antitrypsin is associated with a spontaneous conformational transition in the molecule which leads to a polymer formation. Mild conditions (1 M guanidinium.HCl), temperature and point mutations within the RSL are the factors that induce polymerisation. Initiation of this process has been associated with the disruption of a salt bridge Glu342-->Lys290. In this paper the interaction of guanidinium ion with Glu342 and Lys290 as well as the effect of this interaction on the mobility of RSL is studied by molecular modelling.
Endoproteinase activities in wheat leaves upon water deficit.
Authors: Zagdańska B , Wiśniewski K
Published: January 2020

In wheat leaves acclimated and non-acclimated to water deficit the azocaseinolytic activities of endoproteinases were increased about 7-fold under drought conditions. Under such conditions both the pH dependence profile and the endoproteinase pattern were also changed. The predominant contribution of serine proteinase (about 50% of total endoproteinase activity) remains unaltered in the drought stressed leaves. Cysteine proteinase was induced to the same extent in the drought-stressed leaves irrespective of the acclimation pretreatment, while the contribution of aspartic proteinase was reduced upon water deficit but in the acclimated stressed leaves was as high as in the non-stressed leaves. These changes in the pattern of endoproteinases seem to imply that the water deficiency affects endogenous proteolysis.
The levels of glycosphingolipids, ceramides, sialic acid and glycogen are changed in plasma membranes of rat platelets harvested during recovery from immune-mediated thrombocytopenia.
Authors: Zdebska E , Soszyńska B , Dobrowolski Z , Kościelak J
Published: January 2020

Plasma membranes of rat platelets produced at normal platelet counts and during early recovery from immune-mediated thrombocytopenia were examined for the contents of carbohydrates, lipids and glycosphingolipids. Glucosylceramide, two monosialo-gangliosides and one disialo-ganglioside were found to be the major glycosphingolipids of platelets. During thrombocytopenia the contents of these glycosphingolipids as well as of ceramides were several fold elevated. Among carbohydrate constituents of platelets and platelet plasma membranes, glycogen content was increased and that of sialic acid decreased. These results are discussed in the light of literature data on relevant biochemical characteristics of megakaryocytes at different stages of maturation and on thrombopoiesis during acute experimental thrombocytopenia.

Published: January 2020

Consumers are nowadays aware of the importance of product availability, as well as the quality and safety of the vegetable content they consume. Vegetable production in emerging markets, especially in contemporary Indonesia, still demonstrates erratic characteristics in terms of quantity and quality. Since the output static depends on several factors that cannot be controlled, such as weather, pests, and any other environment condition. Vegetable factories can represent an alternative solution for managing these problems. However, it is crucial to identify those factors considered relevant by consumers when purchasing vegetables to increase the success of vegetable factories. The survey conducted involved 680 respondents in various major cities throughout Indonesia. The results of the analysis show there to be five product-related factors considered necessary by consumers, namely: availability, physical characteristics, physical condition, branding and packaging and, finally, value for money. This research has practical implication, especially for individual or company that wants to introduce a concept of a vegetable factory in Indonesia. The five-product related factors from this research can be used to define the value proposed to the customer and the marketing strategy to make sure the business will sustain.

Authors: Chai Soo See , Wong Wei Keat , Goh Kok Luong , Wang Hui Hui , Wang Yin Chai
Published: January 2020

Mean daily rainfall of more than 30mm could result in flood hazard. Accurate prediction of rainfall intensity could help in forecasting of flash flood and help to save lives and properties. One of the common machine learning techniques in rainfall prediction is Radial Basis Function (RBF) neural network. Rainfall intensity is classified into four categories, i.e. light (<10mm), medium (11-30mm), heavy (31-50mm)  and very heavy (>50mm) in this study. The rainfall intensity categories is forecasted using the RBF network model utilizing the daily meteorology data for Kuching, Sarawak, Malaysia. The input vectors being considered for the RBF network model are minimum, maximum and mean temperature (°C), mean relative humidity (%), mean wind speed (m/s), mean sea level pressure (hPa) and mean precipitation (mm) for the year 2009 to 2013. The prime focus in this paper is to analyse the ramification of the training data size, number of hidden neurons, and different input variables (i.e. combination of meteorology data) in influencing the performance of the RBF network model. From this study, it could be concluded that, the factor that would influence the performance of the RBF model is only the input variables used, if and only if the network model is equipped with sufficient number of hidden neurons and trained with adequate number of training data. Another interesting observation from this study is that, the RBF network model produced consistent result throughout the testing using a specific hidden neuron number when the RBF network is retrained and tested.

Published: January 2020

The transportation process in the daytime will exposure heat stress on the broiler so that it leads to occur the alteration of metabolism in the broiler’s body and damages some vital organs such as liver and colon. Therefore, it needs to be done a solution to solve those problems. One of those is the supplementation of probiotics. The research method was done by using Completely Randomized Design (CRD) 5 treatments and 4 replications T-0 (Control), T-1 Skimmed Milk +  (Lactobacillus Plantarum + Lactobacillus acidophilus),T-2 Skimmed Milk + (Lactobacillus plantarum + Trichosporon beigelii), T-3 Skimmed Milk + (Lactobacillus  plantarum + Cryptococcus humicolus), T-4 Skimmed Milk +  (Trichosporon beigelii + Cryptococcus humicolus). The data analysis was done by using the ANOVA test. If the result was significant further tested by using an orthogonal test. Afterward, the Duncan test was used for testing the parameter of colon morphometric. The result shows that the probiotic supplementation has no significant result (P>0.05) on a level of protein and colon morphometric. However, it gives a positive effect if compared with control. Meanwhile, the probiotic supplementation gives a significant result (P<0.05) on a level of liver fat. The best treatment is T-3 because it has the lowest value of liver fat. Consequently, the probiotic supplementation can maintain broiler’s performance at post transportation especially in handling heat stress.
On Developing a New 5G Spectrum Usage Fee Model for Indonesia
Authors: Hikmaturokhman Alfin , Ramli Kalamullah , Suryanegara Muhammad
Published: January 2020

This paper reports on the development of the 5G spectrum usage fee in Indonesia. The fee was first applied in 2010 to charge mobile network operators (MNOs) that provided cellular services. However, cellular technologies have improved rapidly from 2G, 3G, 4G to 5G, and many modern innovative cellular services demand larger spectrum bandwidth. Therefore, the existing spectrum usage fee must be revised to meet the needs of the community better and to improve the efficiency and effectiveness of spectrum use. This study modifies the characteristics of the existing cost structure of the Indonesian spectrum usage fee, designing and proposing a new 5G spectrum usage fee model to support 5G technology usage scenarios and maximize the benefits of the mid-band (3.5 GHz), mmWave, or high band radio frequencies (26 GHz and 28 GHz). The new spectrum usage fee model includes spectrum-sharing parameters (non-orthogonal spectrum-sharing and orthogonal spectrum sharing) and private network to optimize the use of the available spectrum because the new proposing formula does not use the nationwide population, but instead, it uses the population within a specific area with both human and non-human (machine) populations. This new model is expected to help regulators prepare 5G technology regulations for application in Indonesia.

Assessing Indonesia Spatial Data Infrastructure Using R for Disaster Management
Authors: Jailani Zakiul Fahmi
Published: January 2020

Indonesia is a country with high disaster risk, entitled to ring of fire as one of the countries, which are surrounded by tectonic plates. The country has been exposed to natural hazards for decades. However, every time the natural hazard hits, the number of casualties remains huge. There is a serious question on how disaster management is going on in Indonesia and what knowledge could help to minimize or even prevent such huge casualties in any disaster occurrences. Big data can be a new approach towards natural disaster management mainly because it has the ability to visualize, analyze, and predict natural disasters. In the openly big data era, it is rather easy to process data with open-source software for managing the post-disaster as well as pre-disaster effect. The question remaining is how well the data is, which will be processed. This paper aims to appraise the quality of Indonesia's spatial data infrastructure using the R programming language in order to address natural disaster management and eventually lower the impact of the disaster. Some of the assessment criteria used in this paper are metadata of the data, positional accuracy, and completeness. The article concludes that Indonesia, as a country with high level of exposure to natural hazards, still lacks in NSDI quality, especially in providing disaster data. The most damaged buildings in Palu, with 2,416 damaged buildings affected. The sub-district of Nunu has the lowest number, with only 1 building damaged. The number of sub-districts with damaged buildings in Palu is 14 of the total 43 sub-districts.

Authors: Ahmad Izyani , Sheikh Abdullah Siti Norul Huda , Raja Sabudin Raja Zahratul Azma
Published: January 2020

In practice, most hospitals use light microscope to examine the smeared blood for blood quantification. This visual quantification is subjective, laborious and time-consuming. Although automating the process is a good solution, the available techniques are unable to count or ignore the clumpy red blood cells (RBC). Moreover, clumping cell can affect the whole counting process of RBC as well as their accuracy. This paper proposes a new quantization process called concavity point and skeleton analysis (CP-SA) for heavily clump RBC. The proposed methodology is based on induction approach, enhanced lime blood cell by using gamma correction to get the appropriate edges. Then, splitting the clump and single cells by calculating each object area in pixel. Later, the quantification of clumpy cells with the proposed CP-SA method is done. This algorithm has been tested on 556 clump RBC taken from thin blood smear images under light microscope. All dataset images are captured from Hematology Unit, UKM Medical Centre in Kuala Lumpur. On all tested images, the cells of interest are successfully detected and counted from those clump cells. A comparative study and analysis to evaluate the performance of the proposed algorithm in three levels of clump have been conducted. The first level was with two clumps, second level with three clumps and third level with four clumps. The counting number of clump cells has been analyzed using quantitative analysis, resulting in much better results compared to other recent algorithms. The comparison shows that the proposed method gives better precision result at all levels with respect to ground truth: two clump cells (92%), three clump cells (96%) and four clump cells (90%). The results prove that this study has successfully developed a new method to count heavily clump RBC more accurately in microscopic images. In addition, this can be considered as a low-cost solution for quantification in massive examination.

Ball handling and dribbling are basics soccer techniques. Therefore, handling and dribbling mechanism becomes important component for MSL (Middle Size League) robot soccer. The implementation of active handling and dribbling systems aims to enable the robot to perform dribbling mechanism when maneuvering, while in idle position use handling mechanism. Feedforward and feedback applied as control method in active ball handling and dribbling system. Feedforward control method will give a response to the dribbler wheel based on the motion of robot movement against x, y, and Î¸ axes. Whereas, Feedback control method applied fuzzy inference system by reading the displacement of the arm angle from sensor databased on angle reference of dribbler arm to keep the ball in an ideal position. Implementation geometric calculation for feedforward control toward x, y, and Î¸ axes movement of the robot that it has resulted RMSE value for left motor is 5.75 and for right motor is 7.01. Fuzzy inference system method is used as a feedback control to manipulate the speed and direction of wheel’s rotation as a result ball remains in the ideal position. The value of arm angle displacement and the combination of the two-dribbler arms are used as input for fuzzy inference system. The results of this research show that the application of the combined feedforward and feedback control methods in active handling and dribbling systems can provide robot-dribbling capabilities. Consequently, the robot has a good ability in handling and dribbling mechanism.
Implementing a Web-based Application for Analysis and Evaluation of Heart Rate Variability Using Serverless Architecture
Authors: Gospodinov Mitko M. , Gospodinova Evgeniya
Published: January 2020

This article is devoted to the development of a web-based application for analysis and evaluation of Heart Rate Variability (HRV) using serverless architecture. Advancements in information algorithms and computing technologies have been playing an increasingly important role in cardiology, as continuous monitoring of patients’ health can be vital to their well-being.  One physiological parameter that can be easily measured and that can provide indispensable insight into the state of the human body is the HRV.  HRV analysis can assess not only the physiological state of the body but also provide the capability to monitor its dynamics and predict future diseases. As the research in the sphere of cardiology is constantly growing there is a multitude of new ways to assess the physiological state of patients and provide an early indicator to pathological conditions. Therefore, there is a need to bring these advances to a growing number of end-users (health-care professionals and patients) in the shortest possible time. To address this problem, this study proposes the development of a web-based application for analysis and evaluation of HRV by applying linear and nonlinear mathematical methods. The application is created using a serverless architectural approach, which allows for fast development time, as there is no need to manage server infrastructure, and for automatic scaling to dynamically match the number of requests. The developer can instead focus on implementing the logic for the HRV analysis algorithms and deliver new improvements at a faster rate. The proposed web application can be accessed by any device that is connected to the Internet and is optimized to handle both an intermittent and a consistent volume of requests. The algorithms implemented in the web application have been validated by examining two groups of subjects (young adults and older adults) using linear and non-linear models. The obtained results from the two groups can be compared with a set of reference values (only for the linear methods) and an assessment can be made whether each studied parameter is within the normal range or outside it (its value is too high or too low). To aid the assessment for HRV, the results obtained by the linear and nonlinear analysis are presented using a set of both graphs and tables.

This process represents an innovative way of treating sludge and other shovelable residues deriving from sludge treatment with centrifuges and other industrial processes taking place in large installations, such as refineries, steel mills, chemical plants, glass processing installations, cosmetics manufacturing facilities, pharmaceutical plants. The process is under development within the research project TAFIPACC funded by Horizon 2020. In particular, the process allows retraining Industrial Sludge into construction materials using the new Closed Cycle Drying Process. The study deals with sludge produced by an industrial treatment plant/industrial discharges and civil waste water in the industrial area of Priolo Gargallo (SR) Esso-Erg-Enichem petrochemical plants and by the municipalities of Priolo Gargallo, and Melilli. The plants produce about 30 cubic meters of sludge per day, disposed of 50% in underground dumps and for the other 50% in hazardous and non hazardous waste recovery plants. The difficulty in the treatment is mainly due to the nature of these muds, as pasty and difficult to mix with additives (cement, limestone, H2O, granulometric mix). The presence of bad odours derives from light and heavy hydrocarbons, aromatics, and organic solvents (benzene, toluene, styrene, xylene, etc), causing some problems to operators and inhabitants living in the areas surrounding the plants.

Philippines is one of the world’s leading exporter of mangoes. The country produces many varieties of mangoes, one of which is the ‘Carabao’ mango. Several metric tons of mangoes are produced, and these have to be checked for defects before entering the market. With recent advances in technology, it has become efficient and relatively easy to use for these applications. The objective of this paper is to present a non-destructive method to check the quality of mangoes using computer vision (CV) and convolutional neural network (CNN) with a minimal number of samples. An experimental setup was created to simulate a production line. A webcam was used for capturing images of the mangoes, while a mini computer was used for controlling the peripherals. As basis for categorizing the mangoes as either good or bad, the Philippine National Standard (PNS) for mangoes was used. A basic background subtraction algorithm was used to extract the mango’s image. With these extracted images, a 2-category network was trained, and the achieved classification accuracy was 97.21%. The goal of having a high accuracy in classifying mangoes was achieved. There are multiple paths to explore in the future, including additional feature extraction methods, different neural networks, and hardware improvements, in order to speed up the sorting process. Moreover, it may be necessary to be able to identify mangoes with only slight defects to be used for other products, such as dried mangoes, to reduce product wastage.
NAEA 45 anos: uma utopia criadora
Authors: Vaca Luis Aragón
Published: January 2020

Este paper é uma visão pessoal sobre os alicerces do NAEA, seus propósitos, sua trajetória, seus alcances e desafios de alguém que acompanhou sua história desde 1976, durante 42 anos, portanto. Auxilia-se com documentos oficiais sobre a criação do NAEA, e textos sobre sua produção e trajetória, escritos por diversos autores, sobretudo, de casa, destacando os elaborados por Armando Mendes. Utopias criadoras são ideias norteadoras em busca sempre de uma “luz no fim do túnel” que mesmo sem ser totalmente alcançada, estimula a criação de novos conceitos e metodologias. Nesse contexto, o NAEA foi concebido como uma instituição integradora do fazer universitário, capaz de romper com estruturas e conceitos vigentes na época ancorados no positivismo. Na construção dessa utopia, o NAEA foi visionado envolvendo três pilares interdependentes que o identificariam e imprimir-lhe-iam personalidade própria. Os três pilares se resumem nos conceitos-chave de Desenvolvimento, Interdisciplinaridade e Amazônia. O desafio, ou utopia criadora, está precisamente em dar novos conteúdos a esses conceitos, e fazer deles ferramentas capazes de se aproximar à realidade amazônica e transformá-la. Após 45 anos, como o NAEA vem respondendo a esse desafio? É o que se pergunta neste paper. Palavras-chave: NAEA. Utopia criadora. Amazônia. Desenvolvimento. Interdisciplinaridade.

Técnica, espaço e tempo: grandes objetos urbanos e a difusão da metropolização na Amazônia brasileira
Authors: Sousa Isaque Dos Santos , De Lima Susane Patrícia Melo , Dos Santos Tiago Veloso
Published: January 2020

O artigo analisa a importância das metrópoles de Belém e Manaus como estruturas urbanas de maior expressão da difusão da metropolização na região amazônica, tendo em vista que a atual configuração dessas cidades passa pela produção de grandes objetos urbanos, cujo papel é essencial na indução da expansão de suas estruturas metropolitanas. Tal fato pode ser observado a partir da construção deles no contexto de efetivação da metropolização regional. A teorização proposta por Santos (2008) acerca da importância dos grandes objetos na Amazônia é o ponto de partida desta reflexão, bem como a tendência atual da metropolização do espaço. Sob o aspecto metodológico, estabeleceu-se como percurso desta pesquisa: i) o levantamento bibliográfico da temática analisada; ii) levantamento documental acerca dos grandes objetos aqui destacados; iii) coleta de iconografia representativa da época em que esses objetos são efetivados no espaço urbano. Assim, aponta-se uma metropolização regional que engendra novas configurações espaciais, ora densas e bem articuladas, ora descontínuas e dispersas quando se comparam as duas realidades empíricas, podendo-se contrapor processos históricos e naturais aos processos políticos e econômicos do plano global, regional, ou mesmo local, que são produtos de um tempo em que o urbano e o metropolitano tendem a ser hegemônicos.Palavras-chave: Metropolização regional. Grandes objetos. Belém. Manaus.

Published: January 2020

Esse estudo é fruto de uma pesquisa financiada pelo Governo Federal que objetivou compreender três questões: o que o brasileiro faz como lazer? O que gostaria de fazer, mas não faz como vivência de lazer? E por que não o faz? Especificamente, nesse texto tivemos como objetivo abordar as vivências de lazer da população que reside na região norte brasileira considerando o recorte da categoria classe social. A amostra desta investigação foi composta pelos dados dos sujeitos residentes na região norte do território brasileiro com idade superior a sete anos de idade. O instrumento de coleta foi o questionário estruturado, composto por perguntas abertas e fechadas. Os resultados da pesquisa trazem aspectos que demonstram, especificamente, como as pessoas da Região Norte têm vivenciado o lazer, com as especificidades demarcadas pelas diversas classes sociais. Alguns indicadores da pesquisa evidenciam um maior acesso da classe A1 a diversas atividades de lazer, pois estas se tornam mais acessíveis devido as melhores condições financeiras e culturais, como é o caso das turísticas, que para esse grupo se destacou.Palavras-chave: Lazer. Classes Sociais. Região Norte. Práticas.

Authors: Santos Stéfano Da Paixão , Michelon Francisca Ferreira
Published: January 2020

Este estudo está debruçado sobre o processo de tombamento do patrimônio edificado ocorrido na cidade de Baião, Estado do Pará, e seus possíveis desdobramentos políticos e administrativos impelidos ao poder público local. Neste espaço, investigamos no próprio processo em questão, clareamentos sobre os papeis desempenhados entre sociedade civil e o poder do Estado na preservação e proteção do patrimônio cultural, bem como, compreender a efetividade dos instrumentos legais de intervenção e gestão do espaço urbano, tais como a Constituição Federal, Estatuto da Cidade, Plano Diretor Municipal, Lei Orgânica Municipal, entre outros. Desta forma, pautado na experiência vivida ao longo do processo de patrimonialização em Baião, o texto apresenta reflexões focadas na relação entre o projeto de intervenção urbanística em área patrimonializada e a necessidade de desenvolvimento de uma política de preservação do patrimônio edificado e sua área de entorno.Palavras-clave: Patrimônio Cultural. Tombamento. Plano Diretor Municipal. Planejamento Urbano.
Festa, religião e cidade: experiência e expertise

Desde já me escuso de não ter power point para apresentar, do mesmo modo que não tenho facebook, nem twitter. Definitivamente não sou moderna e me recuso a ser contemporânea, no senso atribuído por Agamben. Ora bem, mas o que é ser contemporâneo? Aprendi com Agamben, e peço licença para uma citação longa, mas fundamental relativamente ao que quero pontuar: “Pertence verdadeiramente ao seu tempo, é verdadeiramente contemporâneo, aquele que não coincide perfeitamente com este, nem está adequado as suas pretensões e é, portanto, nesse sentido, inatual; mas, exatamente por isso, exatamente através desse deslocamento e desse anacronismo ele é capaz, mais do que os outros, de perceber e apreender o seu tempo. Essa não-coincidência, essa discronia, não significa, naturalmente, que contemporâneo seja aquele que vive num outro tempo, um nostálgico que se sente em casa mais na Atenas de Péricles, ou na Paris de Robespierre e do marquês de Sade do que na cidade e no tempo em que lhe foi dado viver. Um homem inteligente pode odiar o seu tempo, mas sabe, em todo caso, que lhe pertence irrevogavelmente. Sabe que não pode fugir ao seu tempo.
Regional corruption variability in the European countries
Authors: Linhartova Veronika
Published: January 2020

Quantification of the corruption rate in smaller sub-national areas is still a significantly unexplored area. Sub-national resolution of corruption rate could bring an entirely new dimension to the theory of causes and consequences of regional disparities. There are numerous reasons why to focus on this issue. Perhaps the strongest one is that if corruption negatively affects the economic performance, as many studies claim, the elimination of corruption in certain regions may be the key for the elimination of regional economic disparities and thus increase the economic performance of the state. Analysis of regional corruption may also lead to the creation of regional anti-corruption provisions that can bring a reduction of corruption rate at the national level. The main goal of this article is formulated in this context. A new corruption quantification method reflecting inter-regional differences in the level of corruption in the European countries is designed. Using this method, it is possible to draw a comparison of individual NUTS II regions and identify those which are more affected by corruption than the others. A high level of corruption variability was confirmed for NUTS II regions, especially in Italy. Because of this variability, it could be very deceptive to evaluate the country as a whole from the corruption level viewpoint.
