Engineering Transdisciplinarity in University Academic Affairs: Challenges, Dilemmas, and Progress
Authors: Hyun Eunsook 
Published: May 2019

Since the 1970s the notion of transdisciplinarity and pragmatic approaches to it have challenged the monolithic traditional orientation and procedures of academia. The long tradition of monodisciplinary academic departmentalization in higher education institutions has crippled the development of human knowledge, way of doing, and even world view; ironically, it has hindered understanding of the interconnected and interdependent ecological human and the natural world. Monodisciplinary academic departmentalization has perpetually and inherently limited the discovery of knowledge and its application to complex real-life problems that demand solutions to assure a sustainable and democratic human society. This article presents a discussion of strategic engineering in higher education academic affairs aiming toward transdisciplinary teaching, learning, research, service, and curriculum transformation with an emphasis on challenges, dilemmas, and progress.
Capturando la ciudad: escenas urbanas de Santiago de Cuba | Sketching the city: Urban scenes of Santiago de Cuba
Authors: Valdés Roberto Rodríguez , Suárez Milene Soto 
Published: May 2019

Nacido en 1969 la ciudad de Santiago de Cuba, Roberto Rodríguez Valdés desde su niñez experimentó una particular pasión por el dibujo. Al igual que sucede a casi todos los infantes, advertía un disfrute singular al captar imágenes del medio circundante a través de trazos y sombras sobre el papel, seducido por el mágico proceso de reproducir y fijar un instante en el tiempo. Así transcurrió poco más de un lustro de su vida hasta encontrarse con la Arquitectura; carrera de la que se graduó en el año 1995. Fue entonces que descubrió la verdadera dimensión del dibujo y comprendió cuan definitiva sería su asimilación como herramienta fundamental para la comunicación.
Multi Band Metamaterials Absorber for Stealth Applications
Authors: Al-badri Khalid Saeed Lateef 
Published: May 2019

Purpose – This paper presents a simulation study using CST microwave studio computer software.
Methodology/approach/design – A simple structure based on metamaterial are used to construct a perfect metamaterial absorber. It is made of just one uncompleted square patch copper placed on top of dielectric layer to separate it from a copper ground plate.
Findings – This design provides four perfect absorption regions with absorption peaks of an average of 93%. The characteristic study of parameters such as copper dimensions and dielectric properties led to an expected result in the synthesis of resonant frequency.
Practical implications – The multi-band absorption can be used in energy harvesting applications, protection from the effects of electromagnetic waves, radar stealth technology and thermal imaging. Moreover, the experimental results show good agreement with CST simulation.
Acceptance sent through email; is the postal rule applicable?
Authors: Defossez Delphine 
Published: May 2019

Purpose – This paper focuses on the application of the postal rule to email, due to the controversy surrounding the application of the “instantaneous” test to emails.
Methodology/approach/design – This article analyses standards and literature on the formation of contract under English law.
Findings – Although the postal rule is an invention of its time, this rule could still play a role regarding emails. Indeed, due to the difficulties in applying the “instantaneous” test to emails, emails would still be subject to the postal rule. Of course, the postal rule in its current form is no more fitting the reality. However, the benefits that such rule provides should not be lost, instead a new rule could be drafted based on the postal rule.
Practical implications – This article discusses the possible improvements to the already existing framework.
Originality/value – This paper analyses the use of the postal rule to electronic contracts in the UK, a topic that is not much researched but could have great importance when doing electronic business.
O impacto da EC 95/2016 e da PEC 287/2016 para a Previdência Social brasileira
Authors: Rocha Flávia Rebecca Fernandes , Macário Epitácio 
Published: May 2019

O artigo discute a Emenda à Constituição (EC) nº 95/2016, aprovada no Congresso Nacional em dois turnos em cada casa, que instituiu novo regime fiscal para o País e a Proposta de Emenda à Constituição (PEC) nº 287/2016, que propõe mais uma contrarreforma na Previdência Social. A análise revela que ambas se fundam na perspectiva neoliberal ortodoxa, têm inequívoca natureza antissocial, priorizam os interesses do capital, principalmente os das fraçõesrentistas ao garantir o pagamento de juros e amortizações da dívida pública, e a espoliação dos direitos dos trabalhadores. As duas alterações trarão impactos negativos sobre a proteção social brasileira e desviam o foco daquele que é o cerne do problema, ou seja, a crise de um modelo econômico cuja expressão mais visível são os índices rastejantes de crescimento do PIB mundial. A pesquisa realizada é de natureza qualitativa e lançou mão de análise bibliográfica e documental.
O Sindicalismo da CUT e a Mercantilização do Sistema Previdenciário Brasileiro (2003-2014)
Authors: Andrietta Lucas Salvador , Lemos Patrícia Rocha 
Published: May 2019

Nas últimas décadas, a Previdência Social brasileira vem passando por um processo de desestruturação de suas bases institucionais cuja referência é o princípio de seguridade social inclusiva e abrangente consolidado na Constituição de 1988. Este processo, definido como a mercantilização do sistema previdenciário brasileiro, se consolidou nos anos 1990, e não foi interrompido e nem revertido com a conquista do Executivo federal pelo Partido dos Trabalhadores. Um dos componentes fundamentais de tal processo foi a atuação contraditória da Central Única dos Trabalhadores, que tem carregadoem sua agenda, simultaneamente, 1) a intenção de defender a previdência pública, inclusiva e abrangente; 2) a escolha estratégica de incluir a previdência privada no plano das negociações coletivas; e 3) o estímulo e atuação nos grandes fundos de pensão. O artigo apresenta o processo de mercantilização, suas articulações com o arranjo político entre 2003 e 2014 e analisa a atuação da CUT no período.

Authors: Shchekotova A. P. , Bulatova I. A. , Sosnin D. Yu. , Tretyakova Yu. I. 
Published: May 2019

Aim. To study significance of platelet count and values of aspartate aminotransferase and tumor necrosis factor-α in the evaluation of the severity of liver fibrosis in chronic hepatitis C and for the development of fibrosis index calculation formula.Material and Methods. The study included 70 patients with chronic hepatitis C end 30 healthy persons. Liver density was estimated by ultrasound elastography.Results. The correlation analysis revealed strong relationships between the ultrasound elastography findings of fibrosis stage and the platelet count (r=0.83), aspartate aminotransferase (r=0.83), and tumor necrosis factor-α (r=0.81). The optimal separation points of laboratory tests for fibrosis exclusion were identified as follows: platelet count>270×109 /L (test sensitivity=96.2%), aspartate aminotransferase level<44 E/L (sensitivity=96.2%), and tumor necrosis factor-α concentration below 1.9 pg/mL (sensitivity=92.3%). The obtained values of laboratory parameters were used for calculation of the liver fibrosis index. The value of the fibrosis index ranging between 0 and 0.5 indicated the absence of fibrosis (stage F0), the value of the fibrosis index ranging between 0.6 and 2.5 corresponded to the moderate stage of fibrosis (F1-2), and the value of the fibrosis index>2.5 corresponded to the severe fibrosis/cirrhosis of the liver (F3-4) with diagnostic sensitivity of 83% and specificity of 78%.Conclusion. Platelet count, the values of aspartate aminotransferase and tumor necrosis factor-α levels, fibrosis index, and laboratory test data can be used for ruling out fibrosis in chronic hepatitis C patients as well as for stratification of liver fibrosis stages.
VENOUS CONDUITS IN CORONARY SURGERY: OLD PROBLEMS — NEW SOLUTIONS
Authors: Vecherskiy Y. Y. , Manvelyan D. V. , Zatolokin V. V. , Shipulin V. M. 
Published: May 2019

The introduction of autovenous coronary artery bypass grafting (CABG) marked the era of surgical revascularization in patients with coronary artery disease. It provided effective treatment for angina and significantly improved the long-term prognosis. Venous transplants today remain the most popular conduits in coronary surgery due to their availability, ease of harvesting, and the absence of length restrictions. Despite the advantages of autovenous CABG, the main disadvantage is the high incidence of venous graft failure, which represents an important and unresolved problem in cardiac and cardiovascular surgery. On the other hand, the traditional allocation of a large saphenous vein implies the dissection of soft tissues throughout the length of the isolated conduit. Traumatic dissection causes a long-lasting persistent pain syndrome after surgery, frequent abnormalities in skin sensitivity, and a high incidence of wound complications in the lower extremities. These complications lengthen the period of rehabilitation of patients and worsen the quality of life. There is an approach of isolating the vein in a block with surrounding tissues to optimize the long-term functioning of the venous shunt, however, this technique is even more traumatic than the traditional method, and therefore its use is limited in practice. On the other hand, the introduction of minimally invasive methods of isolation allowed to reduce the incidence of wound complications and to improve the cosmetic result, but there is no convincing data regarding the effect on the consistency of shunts in the long-term postoperative period. The problems associated with the use of venous conduits in CABG are multifaceted, and their solutions are necessary to improve the effectiveness of surgical revascularization.

Published: May 2019

Aim. To assess the preoperative morphological state of the brain and the state of cerebral circulation in patients referred for coronary bypass surgery to identify predictors of long-term cerebral disorders.Material and Methods. The study included 33 male patients, divided into 2 groups according to the presence or the absence of distant neurological complications 5 years after surgery. All patients underwent non-contrast computed tomography of the brain and perfusion computed tomography. Computed tomography was repeated 5 years after surgery.Results. The perfusion indices in all measurement zones in patients of the two groups did not significantly differ. Significant differences in width of the third ventricle and ventricular-cranial index between patients of groups 1 and 2 were not identified. The incidence rates of leukoaraiosis significantly differed: leukoaraiosis was detected significantly more frequently in group 2 (78% of cases) than in patients of group 1 (31%), p=0.0455.Discussion. The dimensions of the brain cavity system and the preoperative state of the microcirculatory blood flow were not predictors of long-term postoperative neurological disorders. Five years after surgery, patients of group 2 showed clinical and morphological signs of past ischemic changes, which were not detected in patients of group 1 suggesting that leukoaraiosis was an unfavorable prognostic indicator of postoperative cerebrovascular disorders in the long-term period.Conclusion. When referring a patient with the presence of morphological manifestations of cerebral microangiopathy in the form of the leukoaraiosis phenomenon for cardiac surgery, these patients should be considered at risk requiring administration of the necessary set of measures for the prevention of long-term cerebral disorders.

HFACS Analysis for Investigating Human Errors in Flight Training Accidents
Authors: KILIÇ Bilal 
Published: May 2019

Training of pilots in civil aviation is the primary concern when dealing with accidents and incidents. There has been too little research into accidents during flight instruction. To advance the literature, the present study aims to analyze accidents during the instructional general aviation flights. This study examined investigation reports of 70 accidents involving instructional general aviation flights in the United States between 01.01.2018 and 12.12.2018. The data of those accidents was recorded by the national transportation safety board (NTSB).The causal factors of those accidents were statistically analyzed and classified by using the Human FactorsAnalysis and Classification System (HFACS). To the best of our knowledge, this paper is the first ever report analyzing contributing factors of training flight accidents by the analytical framework HFACS. According to the analysis results, it was revealed that across all accidents mentioned above, skill-based errors were ranked as the primary contributing factors, followed by environmental factors, and decision errors. Results showed that the most common skill-based errors are student pilots’ improper landing flare and failure to maintain directional control during landing and takeoff. The findings of this study provide intriguing insight that may be beneficial to people researching contributing factors of aviation accidents in academia and practice. Furthermore, the outcome of the current study may assist student pilots in completing safe flights.

Tujuan dilaksanakannya pengabdian masyarakat ini yaitu untuk menjelaskan bagaimana strategi pengenalan membaca kosakata bahasa Inggris melalui metode phonics bagi Guru di wilayah Jagakarsa Jakarta Selatan semester Gasal 2018/2019 dan menjelaskan produk luaran yang dihasilkan melalui strategi phonics dalam kegiatan pengabdian masyarakat ini. Metode phonics merupakan salah satu metode membaca yakni “Para guru mengajarkan siswa bagaimana bunyi-bunyi huruf itu maupun mencampur bunyi-bunyi secara bersama-sama untuk membentuk kata dan metode bunyi (phonics method) merupakan suatu teknik belajar membaca yang menekankan pada bunyi (lafal pengucapan) yang dihasilkan oleh huruf-huruf yang terdapat di dalam kata (bunyi semacam itu dapat berbeda dari nama-nama huruf ini, seperti dalam bahasa Inggris ketika bunyi huruf c [si] tidak sesuai dengan pengucapan kata [cat].” Selain itu, kelebihan metode ini adalah memudahkan siswa membuat hubungan otomatis antara kata dan bunyi, siswa dapat membunyikan dan membacanya sendiri. Pembelajaran bahasa Inggris menggunakan instruksi phonics lebih efektif daripada belajar membaca tanpa instruksi phonics. Mengacu pada hal tersebut disarankan bahwa bagi sekolah diharapkan mampu mengarahkan guru untuk menggunakan metode atau strategi pembelajaran yang mempu menarik antusias siswa dalam belajar serta menciptakan suasana kelas yang nyaman dan menyenangkan. Bagi guru, ketika pembelajaran berlangsung diharapkan ada dua orang guru atau lebih untuk mengondisikan serta diharapkan guru berbicara secara tepat dan lantang ketika pembunyian huruf phonics sehingga siswa mampu mendengar dengan jelas.
DE KANT A HONNETH: UM ENSAIO SOBRE A LIBERDADE E SUA ADEQUAÇÃO CONSTITUCIONAL
Authors: Massaú Guilherme Camargo , Bainy André Kabke 
Published: May 2019

<span>O conceito “liberdade” é tema central de debates de esferas do conhecimento como a filosofia moral, política e do direito. Reconhece-se que as respectivas digressões teóricas têm acompanhado o caminhar das civilizações contemporâneas. Isso porque a liberdade, mais do que uma construção teórica, diz respeito ao “mundo da vida”, ao “ser com os outros” e àquilo que há de mais concreto e imanente na existência e experiência humanas. Não poderia ser outra a razão do direito se apropriar do conceito e de suas significações, atribuindo normatividade (na forma de direitos e garantias) à liberdade. A questão que parece ser ainda (e constantemente) necessária de ser retomada é a busca por fundamentos teórico-filosóficos da <em>liberdade jurídica</em>, de modo a se compreender as próprias dimensões da palavra, mas, além disso, as próprias premissas racionais que as justificam. Assim, o presente artigo pretende fazer um comparativo entre autores de diferentes épocas – a saber, Kant, Hegel Rawls e Honneth - que desenvolveram, ao menos tangencialmente, a temática da liberdade jurídica, de modo a se viabilizar uma análise comparativa quanto à mudança, ou não, da fundamentação teórica utilizada pelos mesmos. Os métodos de pesquisa empregados foram o histórico e o analítico. O histórico teve como objetivo traçar o pensamento dos autores em comento, considerando-os de um modo historicamente situados no tempo. O analítico foi utilizado para se poder retirar as consequências das informações colhidas e responder ao problema de pesquisa.</span>

Crystal structure and compressibility parameters of benzene and a number of polycyclic aromatic hydrocarbons (PAHs) were calculated by first-principles methods of the density functional theory with a gradient approximation of the exchange-correlation potential in the form of PBE, taking into account the van der Waals interactions optPBE-vdW in a pressure interval of 0–20 GPa. A comparison with the experimental data for benzene, naphthalene, tetracene, and pentacene shows a high accuracy of the calculations. All studied materials have a close compressibility with the bulk modulus from 8 to 12 GPa and its pressure derivative 6.9–7.5, which consistent with a decrease in the intermolecular distances and a weak deformation of the molecules and benzene rings themselves. There is a weak dependence of the compressibility on the number of atoms (benzene rings) in the molecule or on the type of crystal structure (most PAHs have a space group P 21/a). Compounds with a large number of benzene rings, as well as a denser ring structure – cyclic (pyrene, coronene) have lower compressibility with respect to less dense PAHs (tetracene, hexacene). Some PAHs, benzene, phenanthrene, pyrene and coronene, have high-pressure modifications, but a correct description of their structures, which allows to obtain elastic modules, has not yet been made. The obtained data on PAH compressibility can be used in the development of high-temperature equations of state and calculation of the equilibrium composition of the liquid and solid components of the C-O-H system.
