Authors: Rambabu Kalathiripi , Venkatram N
Published: March 2018

The phenomenal and continuous growth of diversified IOT (Internet of Things) dependent networks has open for security and connectivity challenges. This is due to the nature of IOT devices, loosely coupled behavior of internetworking, and heterogenic structure of the networks.  These factors are highly vulnerable to traffic flow based DDOS (distributed-denial of services) attacks. The botnets such as “mirae” noticed in recent past exploits the IoT devises and tune them to flood the traffic flow such that the target network exhaust to response to benevolent requests. Hence the contribution of this manuscript proposed a novel learning-based model that learns from the traffic flow features defined to distinguish the DDOS attack prone traffic flows and benevolent traffic flows. The performance analysis was done empirically by using the synthesized traffic flows that are high in volume and source of attacks. The values obtained for statistical metrics are evincing the significance and robustness of the proposed model

Authors: Yadlapati Avinash , Hari Kishore K
Published: March 2018

Low power Design is the challenge for the current SoC Designers. With the growing complexity of the chips and the shrinking technology, power consumption in ASIC’s has become a major challenge for the ASIC Engineer. The low power challenge is at every level of the ASIC Design flow. The low power techniques are applies at the Micro architecture level, RTL Design Level, Functional Verification level, Logic Synthesis level, Design for Test level, and Physical Design level. Nowadays, with the complexity gradually increasing at the SoC level, some of the EDA companies like Synopsys and Cadence are integrating the low power techniques in the tool itself. For instance, the two most commonly used low power flows are Unified Power Format (UPF) and Common Power Format (CPF). The Unified power format is from Synopsys flow while the Common Power format is from Cadence flow. In this paper, the emphasis is on reducing power by taking an Asynchronous FIFO with two separate clocks and applying the Unified power format flow in it. This paper presents the results of the research reported by the Synopsys Design Compiler before applying the UPF flow and after applying the UPF flow.

(ii) Information will be transformed into required protocol format (iii) uses a light weighted protocol for transmitting the data to cloud and receiving the data from the remote location through computer or through a mobile phone. (iv) provides local storage in the gateway and puts into cloud for analyzing and future use of the received and transmitted data (v) The sensors data can be observed and controlled over a mobile phone, tablet or a personal computer.
Secure and effective random paths selection (SERPS) algorithm for security in MANETs
Authors: Suma P , Ali Hussain Mohammed
Published: March 2018

Mobile Ad-hoc Networks (MANETs) are wireless and nodes of it are mobile in nature. These networks can be adopted where equipment like wires cannot be established and the nodes are moving. Due to the mobile nature of nodes, a fixed topology cannot be achieved. This leads to a dynamic or ever changing network structure. The paths between the communicating nodes also change frequently. Overall monitoring system is absent in it i.e. supervising node is not present for establishing routes in the network. Each node itself acts as a router. Due to the lack of fundamental management system and ever moving nodes, security becomes a challenge and detection of attackers also becomes tough. Dynamic source Routing (DSR) is used in route discovery. In this routing strategy, paths are established only on demand of sender and receiver nodes. And to reduce the cost many algorithms were proposed, but the concept of security is deficit in them. In this paper, Secure and Effective Random Paths Selection (SERPS) algorithm is proposed with the concepts of minimum cost and node disjointness to achieve security. All the node disjoint paths between sender and receiver are found. Among them a minimum of 4 minimum cost paths are selected. Then data packets are sent through them by randomly selecting the paths. Care is to be taken such that no consecutive packets go through the same path. By this, attacker at any node gets only the random packets but not the complete data. In this way security can be achieved. The simulation for the proposed SERPS algorithm is done to show the routing process.

Published: March 2018

Neck pain or cervical pain is most common in individuals who are all working in seated postures for prolonged period of time, example computer users. The pain caused by extreme postural positions including forward head postures and extension angle maintained in cervical. The use of cervical vertebra traction therapy has increased as a part of rehabilitation medicine. However, lack of usability standard in this traction therapy i.e., the exact instructions on how to choose the traction force and location are unclear. To fix this issue, first, the cervical spine traction system analysing the change of cervical spine depending on the traction location has been investigated. Motion analysis systems are widely used to measure the changes in the body part movement. However, the precision and repeatability of motion analysis systems are not much studied. In this paper, the precision and repeatability of a three-dimensional (3D) motion analysis system (i.e., NDI’s Optotrak Certus (OC)) is evaluated with developed 3D robot for traction therapy as an application example. The 3D robot quantitated the accuracy and precision of the system regarding angle and distance. Angle and distance among markers showed good agreement between measurements, and comparable measures of precision reported. Experimental results demonstrate a measure of precision and repeatability for the movement of the patients on the cervical traction system; hence the repeatability was satisfactory.

Authors: Snekhalatha U , Ashok Kumar D , Javasan Padma
Published: March 2018

Background: Low bone mineral density increasing with age is a universally observed phenomenon. This leads to osteoporosis, which is a regressive change that occurs in the bone and it is diagnosed before the occurrence of fractures. The dual energy x -ray absorptiometry (DXA) is considered to be the standard measurement for the detection of bone mineral density (BMD).Objectives: To measure the various bone mass indices in the clavicle bone by radiogrammetric method from a posterior-to-anterior (PA) view of chest digital X-ray using semi- automated method.Methods: Forty women whose mean age was found to be 46.05±15.53 years were included in this study. For the total population (n=40), the right femur BMD was acquired by DXA scanner. The digital chest radiographs were taken for all the subjects. In all cases, the geometrical variables such as periosteal width (CLR-D), endosteal width (CLR-d), cortical thickness (CLR-CT) and percentage cortical thickness %(CLR-CT) were measured in the right clavicle bone region by semi-automated method approach developed in MATLAB software.Results: The CLR-CT (r=0.77) as well as with % CLR-CT (r=0.72) has provided statistically significant correlation (p < 0.01) with the total hip BMD in the total population studied. The pre-menopausal and post-menopausal of the studied population demonstrated a high significance value of (p < 0.01).Conclusion: The semi-automated measurement of low bone mass indices in clavicle radiogrammetry will be useful in the evaluation of low bone mass in post-menopausal women and elderly aged population. This method can be used as a screening tool for mass population, especially in rural India.

Authors: Shaikh Samir , Kulkarni Sham
Published: March 2018

The theoretical model with 2 degree-of-freedom system is developed for predicting the vibration response and analyze frequency properties in an extended type defective ball bearing. In the mathematical formulation, the contact between the races and rolling element considered as non-linear springs. The contact forces produced during the collaboration of rolling elements are obtained by utilizing Hertzian contact deformation hypothesis. The second order nonlinear differential equation of motion is solved using a state space variable method with the help of MATLAB software and the vibration acceleration response of the defective ball bearing presented in the frequency spectrum. The effects of variation in speed and size of the defect on characteristic frequency of extended fault on the outer raceway of the ball bearing have been investigated. The theoretical results of the healthy (non defective) and defective bearing are compared with each other.

Authors: Telagathoti Pitchaiah , Aparna Moparthi , Sridevi P V
Published: March 2018

Due to huge demand for high data rate transmission, there is requirement for efficient design of Digital Down Converter (DDC) in wireless communications. DDC is an indispensable part in modern communication, as for higher frequencies it is difficult to down convert the frequency directly to the baseband frequency. Hence a super heterodyne receiver is used to convert the received signal into an intermediate frequency and the intermediate frequency is then converted into the baseband frequency. The architecture of DDC mainly consists of two parts; first one is demodulation and second one is decimation system. The first stage performs the demodulation and the second stage decimation system performs the operation of filtering and decimation. This paper discusses the design and FPGA implementation of DDC for the LTE-SDR receiver for band5 in LTE(UMTS) standards. The design and FPGA implementation of DDC for LTE-SDR is developed and tested using SystemVue software and Xilinx ML507 FPGA board. The results show that simulation results and FPGA implementation results are very close to each other, so the designed DDC can be used in real time LTE SDR application with hardware as FPGA for efficient processing of data with minimum number of resources and at higher operating frequency.
Imaging of colorectal cancer – the clue to individualized treatment
Authors: Tamandl Dietmar , Mang Thomas , Ba-Ssalamah Ahmed
Published: March 2018

Colorectal cancer (CRC) is the most common gastrointestinal neoplasm and the second most common cause for cancer-related death in Europe. Imaging plays an important role both in the primary diagnosis, treatment evaluation, follow-up, and, to some extent, also in prevention. Like in the clinical setting, colon and rectal cancer have to be distinguished as two quite separate entities with different goals of imaging and, consequently, also different technical requirements. Over the past decade, there have been improvements in both more robust imaging techniques and new data and guidelines that help to use the optimal imaging modality for each scenario. For colon cancer, the continued research on computed tomography (CT) colonography (CTC) has led to high-level evidence that puts this technique on eye height to optical colonoscopy in terms of detection of cancer and polyps ≥10 mm. However, also for smaller polyps and thus for screening purposes, CTC seems to be an optimal tool. In rectal cancer, the technical requirements to perform state-of-the art imaging have recently been defined. Evaluation of T-stage, mesorectal fascia infiltration and extramural vascular invasion are the most important prognostic factors that can be identified on MRI. With this information, risk stratification both for local and distal failure is possible, enabling the clinician to tailor the optimal therapeutic approach in non-metastatic rectal cancer. Imaging of metastatic CRC is also covered, although the complex ramifications of treatment options in the metastatic setting are beyond the scope of this article. In this review, the most important recent developments in the imaging of colon and rectal cancer will be highlighted. If used in an interdisciplinary setting, this can lead to an individualized treatment concept for each patient.

Authors: Ivanova Nevena , Kirov Lyubomir
Published: March 2018

Introduction. This article summarizes the findings of a study about the influence of the factors of external professional environment on the professional motivation and behaviour of Bulgarian general practitioners (GP).

Methods. A representative sample of a total of 4698 GPs in the country was involved in the survey. A special questionnaire was utilized, including 15 factors of external professional environment; these were subdivided into 4 groups on the basis of their nature: financial and economic; legal and regulatory, moral and ethical; and psychological. Their evaluation of the influence of these factors on the professional behaviour and of the factors’ weight was “taken” by means of a direct anonymous survey of 243 General Practitioners (5.2 % of the total number).

Results. The findings of the study indicate that the professional environment in which doctors work affects adversely their motivation and conduct. The majority of the factors examined have a predominantly negative effectwith the exception of the financial and economic ones.

Conclussion. GPs are of the opinion that most influential for their behaviour are the financial and economic factors (net profit; how much they get paid for their activities).

Published: March 2018

The objective of the present research work is to optimize the growth conditions of bi- tri- and few-layer graphene using pulsed laser deposition (PLD) technique. The graphene was grown on n-type silicon (1 0 0) at 530 °C. Raman spectroscopy of the grown films revealed that the growth of low defect tri-layer graphene depended upon Ni content and uniformity of the Ni film. The line profile analysis of the AFM micrographs of the films also confirmed the formation of bi- tri- and a few-layer graphene. The deposited uniform Ni film matrix and carbon/Ni thickness ratio are the controlling factors for the growth of bitri- or few- layer graphene using pulsed laser deposition technique.
Role of structural modifications of montmorillonite, electrical properties effect, physical behavior of nanocomposite proton conducting membranes for direct methanol fuel cell applications
Authors: Abidin K. Sainul , Kannan R. , Palani P. Bahavan , Rajashabala S.
Published: March 2018

Proton exchange membranes have been synthesized from polyimide (PI) doped with different contents of montmorillonite (MMT) which was obtained by solution casting technique. The enhancement of conductivity was achieved through modification with the MMT. Prepared membranes were systematically characterized in terms of ion exchange capacity, water uptake, methanol uptake, swelling behavior and proton conductivity. Fourier transform infrared spectroscopy and X-ray diffraction measurements were used to confirm the structures of the PI/MMT composite electrolyte membranes. SEM surface morphological images of the composite membranes showed that the MMT nanoclay particles were dispersed uniformly within the membrane what was also reflected in XRD results which indicated a good compatibility of MMT particles with the polymer complex. The TGA spectra showed that the thermal stability of the membrane was reduced by adding MMT into the polymer network. The prepared membrane with 10 wt.% of modified MMT exhibited the highest proton conductivity value of 7.06 × 10-2S·cm-1at 70 °C. These results imply the potential application of the PI/MMT composite membranes as improved PEMs for DMFC applications.
Process Metaphysics of Consciousness
Authors: Prentner Robert
Published: March 2018

In this article, we look at the hard problem of consciousness from the perspective of process metaphysics. We thereby identify three problematic premises of the problem that pertain to the constitution of consciousness and its causal relation to the world. We argue for the necessity of re-thinking the corresponding phenomena in terms of internally-structured processes. The hard problem would then cease to be an insurmountable obstacle to a science of consciousness. Furthermore, this line of reasoning is shown to be continuous with philosophical projects from the early 20th century that preceded the contemporary philosophy of mind. Specifically, we investigate the relationship of parts and wholes, and translate metaphysical problems of consciousness into mereological language. Despite this being a philosophical project, we frequently note and discuss links to the empirical sciences, in particular those of quantum mechanics, systems theory and the embodied cognition framework.
Föderalismus im Wunderland: Zur Steuerautonomie bei der Grunderwerbsteuer
Authors: Buettner Thiess , Krause Manuela
Published: March 2018

Die Autoren nehmen die Entwicklung der Steuersätze seit 2006 zum Anlass, die Berücksichtigung der Einnahmen aus der Grunderwerbsteuer im Finanzausgleich zu untersuchen. Im Rahmen einer Simulationsanalyse wird die Entwicklung von 2006 bis 2016 nachvollzogen. Die Ergebnisse zeigen, dass für viele Länder ein starker fiskalischer Anreiz besteht, den Steuersatz zu erhöhen, weil sie dadurch nicht nur höhere Steuereinnahmen sondern auch höhere Zuweisungen erhalten. Bei Ländern, die dennoch auf eine Erhöhung des Grunderwerbsteuersatzes verzichtet haben, zeigt sich verschiedentlich eine paradoxe Situation in dem Sinne, dass mit jedem zusätzlichen Euro an Grunderwerbsteuer ein Rückgang an Transfers einsetzt, der größer ist als der Zuwachs an Steuereinnahmen.
Recent advances in membrane reactors for hydrogen production by steam reforming of ethanol as a renewable resource
Authors: Taghizadeh Majid , Aghili Fatemeh
Published: March 2018

During the last decade, hydrogen has attracted lots of interest due to its potential as an energy carrier. Ethanol is one of the renewable resources that can be considered as a sustainable candidate for hydrogen generation. In this regard, producing hydrogen from ethanol steam reforming (ESR) would be an environmentally friendly process. Commonly, ESR is performed in packed bed reactors; however, this process needs several stages for hydrogen separation with desired purity. Recently, the concept of a membrane reactor, an attractive device integrating catalytic reactions and separation processes in a single unit, has allowed obtaining a smaller reactor volume, higher conversion degrees, and higher hydrogen yield in comparison to conventional reactors. This paper deals with recent advances in ESR in terms of catalyst utilization and the fundamental of membranes. The main part of this paper discusses the performance of different membrane reactor configurations, mainly packed bed membrane reactors, fluidized bed membrane reactors, and micro-membrane reactors. In addition, a short overview is given about the impact of ESR via different catalysts such as noble metal, non-noble metal, and bi-metallic catalysts.
Cartels as Defensive Devices: Evidence from Decisions of the European Commission 2001–2010
Authors: Herold Daniel , Paha Johannes
Published: March 2018

Why would an industry that was not colluding yesterday start colluding today? This article distills insights about cartel formation from 41 cases prosecuted by the European Commission between 2001 and 2010. The case studies examine the events occurring prior to the cartels’ set-up. Cartel formation is affected by changes in prices, demand and customer conduct, capacity utilization, increased imports and entry by competitors, as well as events in the legal and regulatory environment of the firms. Yet, none of these factors serves as a good marker of cartel formation when being regarded in isolation. It rather needs to be analyzed how changes in these factors interact and whether they raise the intensity of competition. In this context, factors that are commonly deemed to destabilize cartels, like entry of new competitors or buyer power, are found to actually foster cartel formation.
Study of Hygrothermal Processes in External Walls with Internal Insulation
Authors: Biseniece Edite , Freimanis Ritvars , Purvins Reinis , Gravelsins Armands , Pumpurs Aivars , Blumberga Andra
Published: March 2018

Being an important contributor to the final energy consumption, historic buildings built before 1945 have high specific heating energy consumption compared to current energy standards and norms. However, they often cannot be insulated from the outside due to their heritage and culture value. Internal insulation is an alternative. However internal insulation faces challenges related to hygrothermal behaviour leading to mold growth, freezing, deterioration and other risks. The goal of this research is to link hygrothermal simulation results with experimental results for internally insulated historic brick masonry to assess correlation between simulated and measured data as well as the most influential parameters. The study is carried out by both a mathematical simulation tool and laboratory tests of historic masonry with internal insulation with four insulation materials (mineral wool, EPS, wood fiber and granulated aerogel) in a cold climate (average 4000 heating degree days). We found disparity between measured and simulated hygrothermal performance of studied constructions due to differences in material parameters and initial conditions of materials. The latter plays a more important role than material parameters. Under a steady state of conditions, the condensate tolerating system varies between 72.7 % and 80.5 % relative humidity, but in condensate limiting systems relative humidity variates between 73.3 % and 82.3 %. The temperature between the masonry wall and all insulation materials has stabilized on average at +10 °C. Mold corresponding to Mold index 3 was discovered on wood fiber mat.
Application and Misapplication of the Czechoslovak STP Cipher During WWII

Published: March 2018

Lieutenant colonel Karol Cigáň (1921-2005), head of the cryptographic unit of the Czechoslovak Ministry of National Defence in the period 1949-1958 was after discharging from this position in Prague relocated to an insignificant and substandard command position at a district military administration in Slovakia. His cryptographic experience was of no use in his new position. To profit from his previous experience as a high qualified cryptographer he started to study the accessible literature and archive materials about the usage of the Czechoslovak cipher systems during the WWII. The result of this his activity were some manuscripts where he deciphered and analyzed some Czechoslovak military wireless telegrams. His critical analysis and his conclusions did not meet an understanding or a positive response of historians and were nor accepted for publication. He had no other chance as to send them to archives. Unfortunately only one (in two copies) and a collection of small notes survived. The aim of this paper is to make decisive technical parts of manuscript [K. Cigáň: Impacts of the decryption of the cipher system of the Czechoslovak Ministry of Defence in London from the years 1940-1945 on the resistance movement. Archive of the Slovak National Uprising, Banská Bystrica, Slovakia, Document collection (Fond) V, manuscript no. S36/90, 46 pp.] about the usage of the socalled STP cipher accessible. Thereby we complement the paper [Š. Porubský: STP cipher of the Czechoslovak in-exile Ministry of Defence in London during WWII, in: Proc. of EuroHCC’17, 3rd European Historical Ciphers Colloq., Smolenice Castle, Slovakia, 2017 (J. von zur Gathen et al., eds.), Slovak Univ. of Technology in Bratislava, 2017, pp. 47-66] where the part of this manuscript containing Cigáň’s method for solving STP cipher which he calls “mathematical” is published. To put Cigáň’s analysis and comment into their historical framework we briefly outline the history of Czechoslovak military intelligence activities with emphasis on their cryptological component.
Connecting the Complexity of MQ- and Code-Based Cryptosystems
Authors: Zajac Pavol
Published: March 2018

We study the connection between the MQ problem and the de­coding problem, through the intermediate MRHS representation. The main goal of this study is to explicitly bound the complexity of solving MQ systems with decoding tools. The main observation is that although the MQ problem over GF(2) can be efficiently transformed to syndrome decoding, the existing general decoding methods are not suitable to solve the system as efficiently as expected from the MQ representation.

Neste trecho são discutidas as nuances entre os dois gêneros literários – com base na pesquisa de Todorov – e como empregar seus conceitos na narrativa de um jogo de RPG. Por fim foram determinadas algumas estratégias a serem tomadas no desenvolvimento dessas concept arts a fim de conquistar a afeição do público-alvo por meio da identificação.
Design como formador de opinião: uma breve discussão entre a construção social de gênero e a estética.
Authors: Siqueira Leonardo Coelho
Published: March 2018

Este artigo busca a discussão do design como formador de opinião, entendendo a profissão designer como uma potente ferramenta social. A partir de revisões bibliográficas, buscou-se investigar a estética no meio social como uma importante forma de comunicação. Nesta problemática, abordou-se a construção social do indivíduo, dentro de um recorte de gênero. A discussão persiste no entender a formação de indentidades no aspecto de gênero, a importância da estética nesse processo e como a estética invidual interage com o seu meio (sociedade). Assim sendo, busca-se subsídios teóricos para uma aplicação de design, para elaborar/solucionar visualmente um material conscientizador e instrucional acerca do tema. Ressalta-se também que este é um recorte de uma pesquisa já em andamento e será apresentada uma discussão breve do tema, que continua sendo pesquisado paralelamente.

HISTÓRICO DA COLEÇÃO LEOPOLDO GOTUZZO: PROCESSOS DE FORMAÇÃO E CONSTITUIÇÃO
Authors: Lizot Joana Soster , Leal Elisabete Da Costa
Published: March 2018

A pesquisa aqui apresentada faz parte dos procedimentos de inventário do acervo do Museu de Arte Leopoldo Gotuzzo (MALG), mais especificamente, da Coleção do patrono no museu, o pintor pelotense Leopoldo Gotuzzo (1887-1983). Elaborada como parte de trabalho de conclusão do curso do Bacharelado em História, está vinculada à proposta do Laboratório de Política e Imagem (ICH-UFPEL). Aborda os processos de formação e constituição da coleção Leopoldo Gotuzzo, a partir das formas de aquisição e preservação desse acervo bem como dos mecanismos que levaram a criação do MALG. Assim, a história da formação da coleção pode ser entendida como uma poderosa fonte para questões relativas à criação de memórias e narrativas, para o papel de instituições museológicas, bem como para a história da arte em Pelotas e mesmo nacionalmente.
O PODER DA IMAGEM ALIADO À FÉ – UM RECORTE A RESPEITO DA CRIATIVIDADE HUMANA A SERVIÇO DA CRENÇA
Authors: Martins Diana Krüger , Bohns Neiva Maria Fonseca
Published: March 2018

A presente proposta contempla um recorte de minha monografia de conclusão de curso, ainda em andamento, intitulada “Arte e Religião – Uma dinâmica de experiências”. O tema principal aborda o uso de dinâmicas como estratégia de ensino, potencializando o processo artístico. Para tal chegar a tal conclusão, estuda-se a importância da experiência, tanto na vivência artística quanto na religiosa. Sendo assim, no primeiro capítulo intitulado “A criatividade humana a serviço da crença”, apontam-se para as associações sobrenaturais com que a humanidade denotou o uso da imagem ao longo dos séculos, até estreitar-se a um panorama que contempla o Cristianismo e sua ramificação protestante. Os principais teóricos utilizados para tal foram BELL (1914) GOMBRICH (1981), CUNHA (2007) e DEWEY (2010).
ARTE SACRA NO RIO GRANDE DO SUL
Authors: De Moraes Vanda Maglione , Santo Renan Espírito , Lemos Denise , Chaves Larissa Patron
Published: March 2018

O presente projeto de pesquisa propõe abordar o estudo sobre as imagens sacras nos séculos XVIII e XIX no âmbito da espiritualidade e assistência no extremo sul do Brasil. Procura-se pensar como algumas práticas culturais europeias, tais como o culto das imagens, chegaram ao continente americano, como se misturaram, recriaram, adaptaram e contribuíram para moldar as sociedades coloniais nessa região. Trata-se de uma proposta de trabalho que objetiva realizar um estudo comparativo no tempo e no espaço. O reduzido número de pesquisas sobre o tema, em especial a iconografia pela missão jesuíta no extremo sul do Brasil, reforça a necessidade de seu estudo e permite-nos alargar o foco de investigação sobre a religiosidade na América colonial. Propõe-se com este trabalho a elaboração de um catálogo que possibilite agir na circulação do conhecimento sobre o tema a partir da história da Arte.
HABITAÇÕES EM BARRO: PATRIMÔNIO CULTURAL E DESCOLONIALIDADE NO POVOADO BARREIRO DO CAFÉ, SÃO RAIMUNDO NONATO. PIAUÍ. BRASIL
Authors: De Oliveira Cícero Ney Pereira de Oliveira , Ferreira Lúcio Menezes
Published: March 2018

O que foi convencionou-se como patrimônio edificado, difundido e amplamente aceito no Brasil, é representado na maioria das vezes pelos grandes casarões e estabelecimentos elitistas que remontam à época colonial e imperial e até mesmo a projetos do início do século XX. Logo, a legitimação do mesmo infere no processo de autoafirmação do indivíduo, apresentando-se como instrumento e objeto de poder; refletindo-se problematicamente na questão do patrimônio arquitetônico brasileiro, representado por uma minoria. A arquitetura espontânea em terra, entendida aqui como patrimônio edificado e patrimônio cultural, é encontrada nos sertões brasileiros como uma alternativa de construção economicamente viável ao sertanejo autóctone. Nesse sentido trabalhamos com edificações em taipa e barro na comunidade rural barreiro do café através do discurso descolonial como lugar de representação do patrimônio e memória de um povo.
ARTES GRÁFICAS EM PELOTAS-RS: A ENERGIA ELÉTRICA E A ILUSTRAÇÃO COMO DISCURSOS DA MODERNIDADE (1936 a 1937)
Authors: Matheus Pedro , Neves Helena De Araujo
Published: March 2018

O objetivo deste artigo é apresentar os resultados parciais de uma investigação realizada junto ao Projeto de Pesquisa intitulado Memória Digital - Digitalização da coleção completa do Jornal Diário Popular de Pelotas. Neste projeto toma-se o jornal como uma fonte de consulta para investigar as artes gráficas em Pelotas-RS – mais especificamente a partir da publicidade impressa e do uso da ilustração. O objetivo deste artigo, contudo, é analisar, por um viés qualitativo, 7 anúncios publicados entre 1936 e 1937 pela The Rio Grandense Light & Power Syndicate Limited – encarregada pela distribuição de energia elétrica em Pelotas de 1914 a 1966. Optou-se pela companhia pela sua presença na cidade por mais de 50 anos, além do seu investimento em reclames praticamente diários. Com o estudo notou-se, dentre outros elementos, uma articulação para vender a energia elétrica como um produto da modernidade criando, em seus potenciais consumidores, um estilo de vida que dependesse da mesma.
A IMPORTÂNCIA DA PRÁTICA NA ABORDAGEM DE ENSINO DA HISTÓRIA DA ARTE
Authors: Carrara Dhara Fernanda Nunes , Bonilha Caroline Leal
Published: March 2018

O presente texto parte de experiências próprias vividas de resultados positivos constatados por disciplinas teórico-prático e oficinas do ensino de História da Arte que ensinam o conteúdo/fundamento teórico juntamente com a parte prática. A História da Arte é passada na maioria das escolas e até mesmo em universidades de forma tradicional, tendendo a desestimular o interesse e importância desse aprendizado, que acaba sendo visto por muitos como cansativo e irrelevante. Entretanto, quando a abordagem do ensino teórico é agregado diretamente com o ensino prático, o fascínio por este estudo é reconhecido como tal, havendo assim, uma maior relevância e aumento do empenho dos alunos com o aprendizado. Portanto, essa pesquisa traz uma reflexão sobre a docência de História da Arte realizada na maior parte das universidades do Brasil e instiga a exploração da parte prática da arte como dependente ao ensino teórico.
