Authors: Mala V , Meena K
Published: March 2018

Traditional signature based approach fails in detecting advanced malwares like stuxnet, flame, duqu etc. Signature based comparison and correlation are not up to the mark in detecting such attacks. Hence, there is crucial to detect these kinds of attacks as early as possible. In this research, a novel data mining based approach were applied to detect such attacks. The main innovation lies on Misuse signature detection systems based on supervised learning algorithm. In learning phase, labeled examples of network packets systems calls are (gave) provided, on or after which algorithm can learn about the attack which is fast and reliable to known. In order to detect advanced attacks, unsupervised learning methodologies were employed to detect the presence of zero day/ new attacks. The main objective is to review, different intruder detection methods. To study the role of Data Mining techniques used in intruder detection system. Hybrid –classification model is utilized to detect advanced attacks.

Published: March 2018

In the recent years, the advance wireless networks and Internet of Things (IoT) are becoming very prominent in assorted domains. In the traffic system, the problem of congestion control is very common, and it is classically handled by the global positioning systems by the drivers as well as traffic administrative authorities. But as the traffic density is increasing day by day, it is becoming difficult to handle and view all the possibilities in the prospective traffic area where the driver is willing to move. Moreover, the problem of security and integrity is also increasing rapidly as there are number of attacks in VANET and GPS systems being used by the crackers by sending the malicious code or fake packets. Ubiquitous computing is one of the recent technologies that is in the phase of implementation under Internet of Things (IoT). In this research manuscript, the approach to integrate the dynamic key exchange with the Elephant Herd Optimization (EHO) is presented to achieve the higher degree of energy optimization and overall lifetime of the network communication. The key concept of the cluster head shuffling using EHO and inner modules of key exchange are simulated in Contiki-Cooja that is open source simulator for advance wireless networks.
Cluster head shuffling based global optimization using elephant herd optimization (EHO) approach
Authors: Sharad Er , Shiwani Savita , Suroliya Manish
Published: March 2018

Wireless Sensors are susceptible from frequent energy decay which leads to the reduction of lifetime of entire network scenario. Such energy loss occurring in the sensor nodes are addressed and worked out by number of researchers using number of methods including Low-energy adaptive clustering hierarchy (LEACH) and its number of variants. Despite of enormous variants of LEACH, there is still huge scope of research because of increasing use of sensor nodes in assorted scenarios. The development of energy aware wireless sensor networks is in research from a long time because of the increasing issues related to lesser lifetime of nodes in the wireless environment. The traditional lifetime of wireless nodes even in smart grids is 835 days while the other wireless nodes die in maximum 30 days. Many times, the battery time of wireless sensor nodes is very few days which is a costly affair. It is difficult and cost consuming to redeploy the wireless nodes to reform the network and cost of clustering. In this research work, a novel and performance aware approach Elephant Herd Optimization based Cluster Head Selection is developed and implemented so that the optimization level can be improved. The nature inspired soft computing approaches are prominently used for global optimization and reduction of error factors from existing results and that is the key focus in this research work.

Published: March 2018

Background and objective: A novel face parsing method is proposed in this paper which partition facial image into six semantic classes. Unlike previous approaches which segmented a facial image into three or four classes, we extended the class labels to six. Materials and Methods: A data-set of 464 images taken from FEI, MIT-CBCL, Pointing’04 and SiblingsDB databases was annotated. A discriminative model was trained by extracting features from squared patches. The built model was tested on two different semantic segmentation approaches – pixel-based and super-pixel-based semantic segmentation (PB_SS and SPB_SS).Results: A pixel labeling accuracy (PLA) of 94.68% and 90.35% was obtained with PB_SS and SPB_SS methods respectively on frontal images. Conclusions: A new method for face parts parsing was proposed which efficiently segmented a facial image into its constitute parts.

Authors: Mansor Zuhanis , Khairulanwar bin Zulkafli Muhammad
Published: March 2018

The initial deployments of antenna in the handset consist of fixed non-rotated antenna for transmitting and receiving the signal in the wireless communication scenario. However, link correlation at the UE shows very bad performance when the handset rotates in landscape position. This paper evaluates the impact of accelerometer on the downlink propagation channel of 3G smartphone for non-line-of-sight links. The performance average received signal power is studied for user equipment. Results show that the exploitation of an accelerometer provide better performance in terms of received signal power when the handset rotated from portrait to landscape position. It can be concluded that the deployment of accelerometer can be used to improve existing 3G smartphone received signal. Results also indicate that accelerometer can be used to improve downlink throughput since the signal-to-noise-power is increased by approximately 16%.

Published: March 2018

One of the main problems with symmetric encryption is key distribution especially when involving large number of users i.e to generate identical keys at different locations. To address this challenge, we proposed a novel algorithm of secret key infusion protocol (SKIP) to generatean identical secret key. While, the key is generated based on a provided image link, starting pattern and string length which must be kept in secret as the algorithm is publicly known. The image from website must be a static image and used as the input of random bits to produce string of hexadecimal values. In a case where image link is compromised, the adversary has to guess other layers of parameters in starting pattern and string length. The generated secret keys were identical at two different locations. In other observation, different secret keys were generated even with the same image link and pattern length but different starting pattern.

Published: March 2018

Representation of Pre-RST information is very useful using visualized elements for realization of benefits of requirement traceability. This improves the practitioner motivation to maintain Pre-RST information during life cycle processes. Few researchers proposed visualization for Post-RST due to which many benefits of requirement traceability cannot be realized. This paper proposed an improved visualization representing Pre-RST information that demonstrates various benefit of requirement traceability. In order to evaluate empirically, an experiment is conducted and textual representation of traceability information is obtained. In order to strengthen our claim a survey is conducted to compare textual representation of traceability information with proposed visualization and results are compiled.

Disparity is inversely proportional to depth. Informationabout depth is a key factor in many real time applicationslikecomputer vision applications, medical diagnosis, model precision etc. Disparity is measured first in order to calculate the depth that suitsthe real world applications. There are two approaches viz., active and passive methods. Due to its cost effectiveness, passive approach is the most popular approach. In spite of this, the measures arelimited by its occlusion, more number of objects and texture areas. So, effective and efficient stereo depth estimation algorithms have taken the toll on the researchers. Theimportant goal of stereo vision algorithms is the disparity map calculation between twoimages clicked the same time. These pictures are taken using two cameras. We have implemented the non-parametric algorithmsfor stereo vision viz., Rank and Census transform in both single processor and multicore processors are implemented andthe results showsits time efficient by 1500 times.

Published: March 2018

In the situations of natural disasters, Wireless Sensor Networks (WSN) is extensively used.  Quality of Service (QoS) is an important parameter for ensuring effectiveness and robustness of service provided.  QoS gets degraded when being applied in various applications of WSN.   Qos expected in WSN applications gets reduced further.  In this case, efficient use of the scarce resources is important to ensure continuous    data transmission is ensured by proficient use of resources which are limited resources. There are many WSN protocols which focus on broadcasting of important information. But there are many parameters which get neglected by these protocols. For instance, normal data traffic gets neglected by these protocols.  Hence, this research proposes EnOPATr system which is independent and distributed. The essential and normal data is handled at the same time in EnOPATr which achieves   dependable and congestion free data. In a sensor node, power consumption can be reduced by decreasing the rate of packet retransmission. This is because of congestion in network.  The simulation of the proposed system is done using NS-2 software which shows that the proposed system is able to reduce network congestion thereby improving the performance..

There are large number of portable application designers are available. Where a few developers make false exercise for making more utilization of their portable application. Due to these duplicate positioning exercises the portable applications enters in the popular application list. The vital point is to raise the avoidance for positioning the duplicate position in portable apps. For this situation huge number of clients makes a fault by downloading the versatile applications which have higher ranking, rating and review. Duplicate ranking indicates the duplicate or unsafe exercises which consists of the reason for bump the apps in popular application list. Utilizing the three confirmations, lastly we are calculating all of those confirmations. Client or user doesn’t have information about the application. So client or user go through the list of the popular applications and downloads or install the applications generally from top page of Application Store. But in some cases it shows that the installed service of application does not work or does not worth. For resolving this duplicity, we make application where we are about to catalogue all the apps which had duplicate ranking. At that point, proposing a process of aggregation which bases on development for combine whole confirmations of the duplicate ranking through the admin and client accounts.

Published: March 2018

One of the challenges that we face from time to time in or daily life is parking our car. It has been estimated that it that 30% of vehicles takes a mean time of 7.8 minutes to occupy a parking spot. This not only leads to a waste of fueland timethat a driver consumes in looking for an appropriate parking spot, but also results in an additional loss ofthe above parameters for the other drivers due to the traffic congestion caused due to slow pace of the driver in search for a parking slot. The solution is to introduce a smart system which is both capable and efficient to solve the problem by not only allowing the end-user to view the available parking spot but also to book the slot in advance there by the user will know well in advance where he should go in order to park his vehicle.
Automated target controlled anaesthesia injector
Authors: Vidhya Lakshmi.S Sri , Luxcy.E Andrews , U Vishnupriya , Haripriya.A Bhargavi
Published: March 2018

Anaesthesia plays a vital role in major operations which lasts for longer duration of time. The anaesthetic condition of a patient is determined by an anaesthetist based on the body conditions and feed the amount of anaesthesia to be delivered into a modern anaesthesia machine, which delivers the drug as instructed. If a patient experience a sudden change in the body condition where the instructed anaesthesia level cannot help, the anaesthetist and doctors will face severe problems during the operation which leads to patient awakening or may even cause death. So, the patient’s body condition has to be continuously monitored and the anaesthesia dosage has to be delivered based on the changes in the body condition. This requires an automated operation of anaesthesia injector which works based on the changes in the patient’s body condition by monitoring the vital parameters by itself. This can avoid over dosage and its side effects, eventually reduces the death rate caused by the improper administration of Anaesthesia.Initially, certain amount of dosage is delivered by the anaesthetist based on the patient’s condition and earlier reports. Then, during the surgery the anaesthesia is administered if required by this ‘Automated Target Controlled Anaesthesia Injector’. Our idea is to monitor the necessary body parameters like temperature, blood pressure, and heart rate by the sensors interfacing it to the microcontroller-PIC16f877a and programmed to deliver the dosage level using stepper motor based on the changes in the parameters. Though, there are so many ideas on automated operation of anaesthesia injector using different micro-controllers and microprocessor, the revolution made in this idea is to use PIC Microcontroller which has an advantage of in-built amplifier, analog to digital convertor & EEPROM coupling with the vital parameters determining the dosage to be administered and assistive mobile-app which helps to reduce the work of anaesthetist by monitoring even from distant places.

The joints fabricated by two sided friction stir welding has shown higher ultimate tensile strength as compared to the joints fabricated by single pass and this trend is common for all the tool profiles.The joining of AA 2024-T351 aluminum plates with dimensions 200 mm ´ 200 mm ´ 5 mm (Length ´ width ´ thickness) was carried out by double pass friction stir welding (FSW) technique. Three friction stir welding tools with different pin height (1, 1.5 and 2) mm were used with different stirring rotation speeds and travel speed, (560, 710 and 900) RPM and (16, 20 and 25) mm/min respectively.The welded specimens were analyzed and evaluated using microstructure, macrostructure, tensile and hardness tests. The results indicated that the yield strength and tensile strength increases as the distance between the two passes (double pass) decrease, the rotational speed of 900 RPM and 560 RPM with travel speed of 16 mm/min and 25 mm/min, respectively is considered to be the most efficient and the width of the gap of the joint line decrease as the distance between the two welding pass decreases.
Arrhythmia recognition and classification using kernel ICA and higher order spectra
Authors: Nanjundegowda Raghu , Meshram Vaibhav
Published: March 2018

Electrocardiogram (ECG) is one of the monitoring methodology for the identification of arrhythmia disease. The conventional methodologies of arrhythmia identification are based on morphological features or certain transformation technique. These conventional techniques are partially successful in arrhythmia identification, because it treats heart as a linear structure. In this paper, ECG based arrhythmia identification is assessed by employing MIT-BIH arrhythmia dataset. The proposed approach contains two major steps: feature extraction and classification. Initially, a combination of non-linear and linear feature extraction is carried-out using Principal Component Analysis (PCA), Kernel Independent Component Analysis (KICA) and Higher Order Spectrum (HOS) for achieving optimal feature subsets. The linear experiments on ECG data achieves high performance in noise free data and the non-linear experiments distinguish the ECG data more effectively, extract hidden information and also helps to attain better performance under noisy conditions. After finding the feature information, a binary classifier Support Vector Machine (SVM) is employed for classifying the normality and abnormality of arrhythmia. In experimental analysis, the proposed approach distinguishes the normality and abnormality of arrhythmia ECG signals in terms of specificity, sensitivity and accuracy. Experimental outcome shows that the proposed approach improved accuracy in arrhythmia detection up to 0.5-1% compared to the existing methods: neural network and SVM based radial basis function.

Designing a Federal Tax on Cannabis
Authors: Oglesby Patrick
Published: March 2018

A Federal tax on cannabis requires answers to several questions: 1. What should we tax? What should be the “base” or bases of a cannabis tax? (Possible bases include: price; weight of various product types [like flower, trim, and concentrate]; and THC content.) 2. Given any base, what should the tax rate be? 3. Should medical cannabis bear full tax? 4. Should marijuana advertising and selling expenses become deductible for federal income tax purposes? (That would treat cannabis businesses like other businesses; current Internal Revenue Code section 280E bars such deductions.) Recently introduced federal legislation provides answers, some more aligned with drug policy than others, to those questions.
Synthesis, characterization and photovoltaic properties of Mn-doped Sb2S3thin film
Authors: Horoz Sabit , Sahin Omer
Published: March 2018

Synthesis and characterization of Mn-doped Sb2S3thin films (TFs) prepared by chemical bath deposition (CBD) at room temperature have been documented and their structural, optical, morphological, magnetic and photovoltaic properties have been examined for the first time. Their structural properties reveal that the Mn-doped Sb2S3TF has an orthorhombic phase structure of Sb2S3, and that the grain size of the Mn-doped Sb2S3TF (72.9 nm) becomes larger than that of undoped Sb2S3TF (69.3 nm). It has been observed that Mn content causes the Sb2S3TF band gap to decrease. This situation clearly correlates with band tailing due to the impurities that are involved. The morphological properties have revealed that the shape of the Mn-doped Sb2S3TF is more uniform than the shape of its undoped counterpart. The study on its magnetic properties has demonstrated that the Mn-doped Sb2S3TF exhibits paramagnetic behavior. Its paramagnetic Curie-Weiss temperature was found to be -4.1 K. This result suggests that there is an anti-ferromagnetic interaction between Mn moments in the Mn-doped Sb2S3TF. Incident photon to electron conversion efficiency (IPCE) and J-V measurements were also carried out for the Mn-doped Sb2S3TF for the first time. The results have indicated that the Mn-doped Sb2S3TF can be utilized as a sensitizer to improve the performance of solar cells. Another important observation on the photovoltaic properties of Mn-doped Sb2S3TF is that the spectral response range is wider than that of undoped Sb2S3TF. Our study suggests that the introduction of dopant could serve as an effective means of improving the device performance of solar cells.

Losing our Senses, an Exploration of 3D Object Scanning
Authors: Eve Stuart
Published: March 2018

3D scanning and photogrammetry of archaeological objects are now becoming commonplace. Virtual 3D scans are in many cases replacing the drawn record and are leading to objects being more easily accessed, shared and analysed. However, the wholesale production of 3D virtual replicas of artefacts is not always supported by adequate information regarding the multi-sensory nature of artefacts. The visual and geometric aspects are well represented, but the sounds and smells of the artefacts are lost. This paper explores the possible consequences of this and provides some indications of how we may remedy the situation, before our 3D archives become senseless.
“Bacon wrapped cancer”: the discursive construction of meat carcinogenicity
Authors: Fusari Sabrina
Published: March 2018

In 2015, the World Health Organization published a report on the carcinogenicity of red and processed meat (IARC, 2015. Carcinogenicity of consumption of red and processed meat. The Lancet Oncology 16(16). 1599–1600), attracting intense interest from both the general public and the scientific community. This study combines corpus approaches, Systemic Functional Linguistics and discourse analysis to investigate and compare scientific and animal rights movement reactions to the IARC 2015 report. Scientific reactions are exemplified by three research papers published immediately after the report; responses from animal rights campaigners are investigated through an analysis of texts taken from the website of the nongovernmental organization PETA. The aim is to explore how discourse not only describes, but also constructs meat carcinogenicity, in texts produced by two discourse communities (scientists and animal campaigners) which, for entirely different reasons, have an important stake in this issue. Qualitative (close reading) and quantitative (corpus-based) methods are combined, focusing on vocabulary, grammatical metaphor, and Appraisal (Martin, Jim and Peter White, 2005. The language of evaluation: Appraisal in English. Basingstoke: Palgrave Macmillan). The results show a high level of hybridity, discursive erasure (Stibbe, Arran, 2012. Animals erased: discourse, ecology, and reconnection with the natural world. Middletown: Wesleyan University Press), and some substantial differences in the discourse reactions to the IARC report by the two sources, reflecting the ideologies and ethical assumptions they espouse in their approach to the announcement that red and processed meat can cause cancer.

In this paper, we propose a new method of Diffie-Hellman key exchange based on a non-commutative integral closure ring. The key idea of our proposal is that for a given non-commutative ring, we can define the secret key and take it as a common key to encrypt and decrypt the transmitted messages. By doing, we define a new non-commutative structure over the integral closure OLof sextic extension L, namely L is an extension of ℚ of degree 6 in the form ℚ(α, β), which is a rational quadratic and monogenic extension over a non-pure and monogenic cubic subfield K = ℚ(β).

As articulações são fundamentadas no conceito de Nigel Cross sobre o “Design Ways of Knowing” e na visão de “Projeto por Cenários” apresentada por Paulo Reyes. Desta reflexão podem surgir recursos conceituais que subsidiem os processos projetuais não só do design mas também de outras indústrias e avanços nos estudos relacionados a construção de cenários.
Workshop e o Design participativo: Uma perspectiva da colaboração designer-cliente
Authors: Halpern Marcelo , Da Costa Filipe Campelo Xavier
Published: March 2018

O presente trabalho se propõe a discutir o impacto da presença de usuários/clientes em uma prática projetual de workshop. Através de uma pesquisa bibliográfica e um estudo de caso estabelece-se uma relação entre tópicos como design thinking, codesign e ferramentas metaprojetuais como o workshop. Como resultado, é sugerido que a atuação de clientes de um contexto de projeto pode influenciar positivamente os resultados de uma prática projetual. Portanto, propõe-se que em determinados contextos as empresas e clientes possam vir a se aproximar do processo de projetação com o objetivo de potencializar a capacidade de implementação dos mesmos.

MOBILIDADE ACADÊMICA E CONHECIMENTO DE NOVAS CULTURAS: A TRADIÇÃO DOS CARETOS EM TRÁS-OS-MONTES – PORTUGAL
Authors: Rossi Flávia Demke , Chaves Larissa Patron
Published: March 2018

Em 2014, enquanto cursava Artes Visuais – Licenciatura na Universidade Federal de Pelotas (UFPel), tive a oportunidade de realizar um intercâmbio acadêmico no Curso de Licenciatura em Arte e Design, no Instituto Politécnico de Bragança em Bragança, Portugal. Esse deslocamento me possibilitou vivenciar diversas experiências no contato com a cultura da região de Trás-os-Montes, no nordeste de Portugal. Ao participar do I Seminário Internacional de Máscaras artesanais em Vinhais, Portugal, fiquei impressionada com aquele fazer artístico/artesanal tradicional da região e carregado de simbolismo. As máscaras são utilizadas pelos Caretos, personagens tradicionais das “Festas dos Rapazes” que ocorrem no período natalino nas aldeias transmontanas, onde a festa adquire contornos particulares. As experiências vivenciadas durante esse percurso, modificaram meu modo de ver e pensar a cultura, o cotidiano, as relações sociais e a própria Educação.
MUSEU E PATRIMÔNIO: UMA REFLEXÃO SOBRE OS ESPAÇOS CULTURAIS DO MUNICÍPIO DE PELOTAS/RS – BRASIL
Authors: Pacheco Paula Lima , Lemos Rosemar Gomes
Published: March 2018

Este trabalho é um recorte de um dos capítulos da minha pesquisa monográfica do Curso de Especialização em Artes pela Universidade Federal de Pelotas - UFPEL, a qual está em andamento. Neste texto abordo algumas reflexões sobre a relação entre museu e patrimônio, aprofundando o tema na realidade vivenciada pela população do município de Pelotas-RS, Brasil. Na investigação percebeu-se que há uma vasta quantidade de museus e patrimônios a partir dessa realidade julgou-se conveniente apresentar uma breve reflexão sobre o histórico pelotense através das exposições permanentes de três museus, sendo eles: Museu do Doce, Museu de Arte Leopoldo Gotuzzo e Museu da Baronesa verificando as culturas valorizadas nos mesmos bem como as invisibilizadas. O artigo finaliza teorizando sobre as causas e consequências dessa diferença de valores no que se refere ao patrimônio cultural material e imaterial.
PROCESSO INTERVENTIVO DE OBRA SACRA – PRINCÍPIOS DE CONSERVAÇÃO E USO. ESTUDO DE CASO NA PARÓQUIA SAGRADO CORAÇÃO DE JESUS
Authors: Cazaubon Jennifer , Chaves Larissa Patron
Published: March 2018

Este artigo apresenta o estudo de caso e procedimentos interventivos de uma cruz processional em metal, com Cristo crucificado, do ano de 1915, pertencente à Paróquia Sagrado Coração de Jesus, mais popularmente conhecida como “Igreja do Porto”, na cidade de Pelotas - RS. O objeto foi recebido para o procedimento interventivo através de um trabalho voluntário da autora junto à Paróquia. O objeto encontrava-se à parte do altar da igreja devido o seu estado de conservação. A mesma está passando por um processo de reforma, tornando seu ambiente desfavorável para a conservação das obras em seu interior. Após retornar ao uso, o objeto sofreu novos danos e mais uma vez foi recebido pela autora para um novo procedimento. Diante disto, tornou-se imprescindível o desenvolvimento de um plano de conservação e conscientização da comunidade católica local para promover a preservação deste patrimônio cultural religioso.
RESTAURO DE PINTURA À ÓLEO SOBRE TELA
Authors: Rodrigues Mara Denise Nizolli , Bachettini Andréa Lacerda
Published: March 2018

Restauração da obra “Descanso da Sagrada Família na fuga para o Egito” pertencente à Coleção de Arte Sacra do Museu da Cidade do Rio Grande, RS, Brasil. Este trabalho é resultado dos procedimentos de restauro realizados na obra, que é uma pintura que se encontrava em ritmo acelerado de deterioração. Tinha seu suporte bastante fragilizado, porém, seu maior dano, eram as perdas de informação na leitura da imagem, em grande parte, da camada pictórica que se encontrava escurecida sob uma camada de verniz suja e oxidada, aplicada em uma intervenção anterior, provavelmente ocorrida por volta do ano de 2000. Neste trabalho de conclusão de curso serão expostos, detalhadamente, todos os procedimentos de restauração realizados na obra, desde sua chegada ao Laboratório de Conservação e Restauração de Pinturas do Instituto de Ciências Humanas da UFPel.

O presente artigo aborda questões diretamente ligadas ao estado de conservação do patrimônio histórico e artístico que faz parte da cultura e da memória da cidade de Pelotas, no Rio Grande do Sul. Trata-se de uma parte da dissertação que estuda o estado de conservação das sete esculturas em bronze que além de serem trabalhos realizados por renomados artistas, elencam um conjunto de obras inseridas na Praça Coronel Pedro Osório, um dos locais mais relevantes do Centro Histórico da cidade. Neste contexto, as obras encontram-se em um estado de degradação que envolvem questões de ordem de envelhecimento natural e ações que não se justificam, como o vandalismo, fatores que influenciam na estética de cada uma, na apreciação in loco pelos transeuntes e degradação do patrimônio público.
ARTE RUPESTRE: UMA EXPERIÊNCIA DE ENSINO E PESQUISA EM ARTES VISUAIS NO PIBID
Authors: Lemos Denise Castanha de Avila , Zamperetti Maristani Polidori
Published: March 2018

O texto busca apresentar experiências na docência em Artes Visuais desenvolvidas no âmbito do Programa Institucional de Bolsa de Iniciação a Docência – PIBID (2014 a 2016), onde realizo oficinas sobre pintura rupestre nas escolas atendidas pelo programa, e também em outras escolas da rede municipal e estadual da cidade de Pelotas. A arte rupestre é uma das primeiras formas de expressão artísticas humanas e promovo, através de oficinas de arte, a construção do conhecimento através da manipulação, experimentação e criação de matérias da natureza, que permitem entender a história e a cultura de uma forma mais dinâmica e atrativa. Com estas atividades busco desenvolver novas metodologias na área de ensino da arte, levando aos alunos o conhecimento sobre a história da arte pré-histórica.

Authors: Apriliana Siska , Agustina Linda
Published: March 2018

The purpose of this study was to analyze the prediction of fraudulent financial reporting with the perspective of pentagon fraud. Pentagon fraud theory is the development of the theories of fraud triangle and fraud diamond. The Pentagon fraud theory adds an element of arrogance in addition to the other four existing elements namely pressure, opportunity, rationalization, and competence or capacity. The population in this study were 157 manufacturing companies listed on the Indonesia Stock Exchange (IDX) period 2013-2015. The samples of 46 companies were obtained by using purposive sampling technique, so the analysis unit was 138. Data was analyzed by using descriptive statistical analysis and logistic regression analysis. The test result showed that financial stability, the quality of external auditor, and the number of CEOs photos in the annual reports of the companies had a positive effect on the prediction of fraudulent financial reporting, while financial targets, liquidity, institutional ownership, monitoring effectiveness, replacement of external auditors, and changes of corporate directors had no significant effect on the prediction of fraudulent financial reporting. The conclusion of this study indicates that unstable financial condition, the quality of corporate audit and the level of CEO's arrogance can influence the occurrence of fraudulent financial reporting.
