Tombamentos, processos, disputas e tensões nas histórias do patrimônio cultural de Joinville – outras questões para o debate público
Authors: Souza Giane Maria , Abrantes Cristiano Viana , Rothert Dietlinde Clara
Published: October 2019

Este artigo analisa as múltiplas variáveis dos sentidos históricos dos processos de tombamentos e inventariamentos do patrimônio cultural de Joinville, Santa Catarina no conjunto de suas políticas públicas. O texto reflete a criação da Lei Municipal nº1773/1980 que institui a Comissão do Patrimônio Histórico Artístico, Arqueológico e Natural (COMPHAN) e a criação da Fundação Cultural de Joinville (FCJ) em 1982, atual Secretaria de Cultura e Turismo (Secult) e da Coordenação do Patrimônio Cultural (CPC) em 1997 e os processos interrompidos e inacabados de algumas políticas públicas. Analisa a luz do tempo presente, a incumbência legal da CPC e da Secult, considerando os atores, os lugares, os bens culturais e os conceitos de patrimonialização constantemente reconfigurados nestes processos históricos por técnicos, sociedade civil, políticas de gestão, historiadores e investigadores da área. Ao refletir sobre as disputas e tensões no campo patrimonial, evidencia-se distintos interesses da sociedade civil e do Estado, contrastados e mediados por técnicos, gestores e historiadores e deliberados pela COMPHAN. Este artigo, enfim, contribui para a análise técnica e avaliação histórica das políticas públicas como processos inacabados e dinâmicos a partir dos debates promovidos e atualizados no Simpósio Patrimônio Cultural: Representações, Apropriações e Disputas no XVII Encontro Estadual de História da Associação Nacional de História (ANPUH) - Memória, Patrimônio e Democracia.
A memória fardada : a criação do Museu Histórico Nacional e as relíquias do Contestado
Authors: Rodrigues Rogerio Rosa
Published: October 2019

O Museu Histórico Nacional foi idealizado para ser um espaço de memória das tradições militares do Brasil. Comprova-o o acervo que deu origem ao museu em 1922 e a trajetória e compromisso político do seu idealizador, Gustavo Barroso.  A proposta deste artigo é refletir sobre os vínculos entre a perspectiva de memória e história de Gustavo Barroso e seus estreitos vínculos com o momento social e político vivido pelo Exército brasileiro após a Proclamação da República. Propõe-se, ainda, levantar algumas hipóteses sobre os vestígios materiais recolhidos por oficiais militares que atuaram na repressão ao movimento do Contestado que fazem parte da reserva técnica do Museu Histórico Nacional. Tem-se como hipótese que as ideias de Barroso e dos militares convergiam em alguns aspectos, a saber, a valorização da história e da memória militar brasileira em um contexto de disputas pela reelaboração da memória nacional.
Campos entre Taipas e Aramados: novos olhares sobre a paisagem serrana Catarinense
Authors: Fortkamp Schuch Cristiane
Published: October 2019

A importância dos estudos sobre a paisagem tem por base as interações de seus vestígios na história, sendo a percepção e o olhar os vetores de transmissão de significados, apresentando se como imagem, no limiar entre a existência física e mental. Desta forma, o presente artigo propõe se a elaborar um exercício de análise sobre a história dos campos de altitude do planalto catarinense, compreendendo que a natureza transformada pela ação humana é consequência de relações materiais, mas também simbólicas que grupos humanos com o meio ambiente, de maneira que os lugares nos quais estão inscritas as existências humanas foram construídos pelos homens, ao mesmo tempo pela sua ação técnica e pelo discurso que mantinham sobre ela, o que os torna reflexivos e produtos de diferentes experiências culturais.
A UNESCO, o patrimônio e o turismo cultural: uma abordagem inicial (1960-1980)
Authors: Serpa Valéria Fernanda Serpa , Sossai Fernando Cesar , Coelho Ilanil
Published: October 2019

Este artigo tem como objetivo socializar resultados alcançados com o desenvolvimento de uma dissertação de mestrado cujas atenções recaem sobre as relações envolvendo patrimônio e turismo no âmbito da UNESCO (1960-1980). O texto encontra-se dividido em três partes. Na primeira, construímos um breve histórico dessa Organização, pontuando discussões sobre patrimônio que atravessaram o processo de elaboração e promulgação da Convenção para a proteção do patrimônio mundial, cultural e natural, em 1972. Em seguida, a partir da análise de fontes coletadas junto ao UNESCO Archives (Paris, França), refletimos a respeito das maneiras pelas quais a UNESCO procurou aproximar patrimônio e turismo cultural no transcurso da década de 1970. Por último, finalizamos este escrito compartilhando duas indagações que se desdobraram do cruzamento entre a bibliografia e a análise das fontes que empreendemos em nossos recentes projetos de pesquisa.

Mulherio na Constituinte (1985-1987)
Authors: Crescêncio Cintia Lima , Da Silva Renata Cavazzana
Published: October 2019

Mulherio (1981-1988), inaugurado em período de abertura política, criado por pesquisadoras da Fundação Carlos Chagas, foi um dos jornais feministas mais longevos no contexto da imprensa alternativa e discutia pautas que visavam construir a igualdade de gênero, bem como sistematizava informações sobre a “condição da mulher” no Brasil. Um dos temas que mobilizou o jornal, e todas as publicações e grupos feministas do período, foi o debate sobre a Constituinte, assunto que foi determinante dos rumos tomados pelo movimento nas décadas seguintes. Nesse sentido, o presente artigo pretende analisar como o Mulherio pautou a máxima, encampada pelo Conselho Nacional dos Direitos da Mulher, da campanha “Constituinte pra valer tem que ter palavra de mulher” em suas páginas em 1985-1987.

Abstract - Chronic kidney disease (CKD) is a global public health problem with an increased prevalence and incidence of kidney failure, poor prognosis and high costs. prevalence values throughout Indonesia for kidney failure have an average value of around 0.2 percent. The first step in managing kidney disease is determining the right diagnosis. Then we need a method to predict chronic kidney disease. Naïve Bayes has several advantages, which are fast in calculations, simple and high accuracy algorithms. The Naïve Bayes Classifier is more appropriately applied to large data and can handle incomplete data (missing value) and is strong against irrelevant attributes and noise in the data. To improve accuracy, Particle Swarm Optimization is used for weighting attributes. From the results of the Naive Bayes Classification research based on Particle Swarm Optimization, the accuracy of confusion matrix is 98.75% and AUC 99% . while Naive Bayes has an accuracy of 97.00% confusion matrix and AUC 99.8%.
QT-prolongation and noncompaction
Authors: Finsterer Josef , Stöllberger Claudia
Published: October 2019

In a recent article, Szulik et al. reported about a 22 years old female with ventricular fibrillation, QT-prolongation, and left ventricular hypertrabeculation/noncompaction (LVHT) who died from hypoxic cerebral damage 5 days after admission [1]. We have the following comments and concerns. Patients with LVHT have a disposition for any type of cardiac arrhythmia [2,3]. This is why ventricular fibrillation not only could be due to hereditary long-QT syndrome but also due to LVHT. Ventricular fibrillation was either due to LVHT or a consequence of QT-prolongation. QT-prolongation is not unusual in LVHT and has been reported in several cases (table 1) [3-7]. LVHT has been also reported in association with long-QT-syndrome due to mutations in the KCNQ1 gene [8], in the KCNH2 gene [9], or due to an unidentified genetic defect (table 1) [10]. In a study of 105 patients with LVHT, the QT-interval increased during a mean follow up of 3.6y in 15 patients and normalized in 21 patients [11]. The increase was associated with the extension of LVHT and the presence of a neuromuscular disorder (NMD) [11].
Cosmological Evolution of the Absorption of γ-Ray Burst X-Ray Afterglows
Authors: Rahin Roi , Behar Ehud
Published: October 2019

X-ray absorption of γ-ray burst (GRB) afterglows is prevalent yet poorly understood. X-ray-derived neutral hydrogen column densities (N
H) of GRB X-ray afterglows show an increase with redshift, which might give a clue for the origin of this absorption. We use more than 350 X-ray afterglows with spectroscopic redshift (z) from the Swift X-ray Telescope repository as well as over 100 Lyα absorption measurements in z > 1.6 sources. The observed trend of the average optical depth τ at 0.5 keV is consistent with both a sharp increase of host N
H(z), and an absorbing diffuse intergalactic medium (IGM), along with decreasing host contribution to τ. We analyze a subsample of high-z GRBs with N
H derived both from the X-ray afterglow and the Lyα line. The increase of X-ray-derived N
H(z) is contrasted by no such increase in the Lyα-derived column density. We argue that this discrepancy implies a lack of association between the X-ray and Lyα absorbers at high z. This points toward the X-ray absorption at high z being dominated by an intervening absorber, which lends credibility to an absorbing IGM contribution.
Radio Emission from Supernovae in the Very Early Phase: Implications for the Dynamical Mass Loss of Massive Stars
Authors: Matsuoka Tomoki , Maeda Keiichi , Lee Shiu-Hang , Yasuda Haruo
Published: October 2019

Recent high-cadence transient surveys and rapid follow-up observations indicate that some massive stars may dynamically lose their own mass within decades before supernovae (SNe). Such a mass-loss forms “confined” circumstellar medium (CSM); a high-density material distributed only within a small radius (≲1015 cm with the mass-loss rate of 0.01 ∼ 10−4
M
⊙ yr−1). While the SN shock should trigger particle acceleration and magnetic field amplification in the “confined” CSM, synchrotron emission may be masked in centimeter wavelengths due to free–free absorption; the millimeter range can, however, be a potential new window. We investigate the time evolution of synchrotron radiation from the system of a red supergiant surrounded by the “confined” CSM, relevant to typical Type II-P SNe. We show that synchrotron millimeter emission is generally detectable, and that the signal can be used as a sensitive tracer of the nature of the “confined” CSM; it traces different CSM density parameter space than in the optical. Furthermore, our simulations show that the “confined” CSM efficiently produces secondary electrons and positrons through proton inelastic collisions, which can become main contributors to the synchrotron emission in several ten days since the SN. We predict that the synchrotron emission is detectable by ALMA, and suggest that it will provide a robust evidence of the existence of the “confined” CSM.

The Transiting Exoplanet Survey Satellite (TESS) is performing a near all-sky survey for planets that transit bright stars. In addition, its excellent photometric precision enables asteroseismology of solar-type and red-giant stars, which exhibit convection-driven, solar-like oscillations. Simulations predict that TESS will detect solar-like oscillations in nearly 100 stars already known to host planets. In this paper, we present an asteroseismic analysis of the known red-giant host stars HD 212771 and HD 203949, both systems having a long-period planet detected through radial velocities. These are the first detections of oscillations in previously known exoplanet-host stars by TESS, further showcasing the mission’s potential to conduct asteroseismology of red-giant stars. We estimate the fundamental properties of both stars through a grid-based modeling approach that uses global asteroseismic parameters as input. We discuss the evolutionary state of HD 203949 in depth and note the large discrepancy between its asteroseismic mass (M
* = 1.23 ± 0.15 M
⊙ if on the red-giant branch or M
* = 1.00 ± 0.16 M
⊙ if in the clump) and the mass quoted in the discovery paper (M
* = 2.1 ± 0.1 M
⊙), implying a change >30% in the planet’s mass. Assuming HD 203949 to be in the clump, we investigate the planet’s past orbital evolution and discuss how it could have avoided engulfment at the tip of the red-giant branch. Finally, HD 212771 was observed by K2 during its Campaign 3, thus allowing for a preliminary comparison of the asteroseismic performances of TESS and K2. We estimate the ratio of the observed oscillation amplitudes for this star to be

, consistent with the expected ratio of ∼0.85 due to the redder bandpass of TESS.

Published: October 2019

Recent high-resolution observations unveil ring structures in circumstellar disks. The origin of these rings has been widely investigated under various theoretical scenarios. In this work we perform global 3D nonideal MHD simulations including effects from both ohmic resistivity and ambipolar diffusion (AD) to model the HL Tau disk. The nonideal MHD diffusion profiles are calculated based on the global dust evolution calculation including sintering effects. Disk ionization structure changes dramatically across the snow line due to the change of dust size distribution close to the snow line of major volatiles. We find that accretion is mainly driven by disk wind. Gaps and rings can be quickly produced from different accretion rates across the snow line. Furthermore, AD leads to highly preferential accretion at the midplane, followed by magnetic reconnection. This results in a local zone of decretion that drains the mass in the field reconnection area, which leaves a gap and an adjacent ring just outside of it. Overall, under favorable conditions, both snow lines and nonideal MHD effects can lead to gaseous gaps and rings in protoplanetary disks.
Ensemble Forecasting of Major Solar Flares with Short-, Mid-, and Long-term Active Region Properties

Published: October 2019

We apply an ensemble technique for major flare prediction by considering short-, mid-, and long-term active region (AR) properties and their relative contributions. For this, we consider magnetic parameters from Solar Dynamics Observatory/Helioseismic and Magnetic Imager and flare lists from Geostationary Operational Environmental Satellites. In this study, we simultaneously consider flaring rates during short- (1 day), mid- (several days), and long-term (several years) timeframes. In our model, the predicted rate is given by a weighted combination of the three rates such that the sum of their weights is 1. We calculate the Brier skill scores (BSSs) for investigating prediction performance and weights of these three terms to provide optimal results. The BSS (0.22) of the model with only long-term properties is higher than that with only short-term (0.07) or mid-term (0.08) properties. When short-/mid-term properties are additionally considered, the BSS is improved to 0.28/0.24. Our model has the best performance (BSS = 0.29) when all terms are considered, and their relative contributions to the short-, mid-, and long-term rates are 20%, 20%, and 60%, respectively. In addition, the model with three terms is more effective at predicting major flares in strong ARs. In view of the energy storage and release process, long-term magnetic properties may indicate the storage of magnetic free energy, while short- and mid-term flare history may reflect a recent trend of energy release process. Our results suggest that the performances of other existing flare models based on long-term properties should be improved by considering short- and/or mid-term flare history.
Further Evidence for Looplike Fine Structure inside “Unipolar” Active Region Plages
Authors: Wang Y.-M. , Ugarte-Urra I. , Reep J. W.
Published: October 2019

Earlier studies using extreme-ultraviolet images and line-of-sight magnetograms from the Solar Dynamics Observatory (SDO) have suggested that active region (AR) plages and strong network concentrations often have small, looplike features embedded within them, even though no minority-polarity flux is visible in the corresponding magnetograms. Because of the unexpected nature of these findings, we have searched the SDO database for examples of inverted-Y structures rooted inside “unipolar” plages, with such jetlike structures being interpreted as evidence for magnetic reconnection between small bipoles and the dominant-polarity field. Several illustrative cases are presented from the period of 2013–2015, all of which are associated with transient outflows from AR “moss.” The triangular or dome-shaped bases have horizontal dimensions of ∼2–4 Mm, corresponding to ∼1–3 granular diameters. We also note that the spongy-textured Fe ix 17.1 nm moss is not confined to plages, but may extend into regions where the photospheric field is relatively weak or even has mixed polarity. We again find a tendency for bright coronal loops seen in the 17.1, 19.3, and 21.1 nm passbands to show looplike fine structure and compact brightenings at their footpoints. These observations provide further confirmation that present-day magnetograms are significantly underrepresenting the amount of minority-polarity flux inside AR plages and again suggest that footpoint reconnection and small-scale flux cancellation may play a major role in coronal heating, both inside and outside ARs.

RESUMOO presente artigo tem por finalidade apresentar um recorte de pesquisa referente à Educação Ambiental Emancipatória (EAE) com perspectiva nas Tecnologias Sociais (TS). Para tanto, foi realizada uma pesquisa descritiva, com abordagem qualitativa e estratégia bibliográfica que permitiu a priori, elucidar conceitos considerados fundamentais para a compreensão dos fenômenos e a posteriori, observar suas relações no campo empírico. No campo teórico foram utilizadas fontes como Oliveira (2000), Loureiro (2012), Lima (2005) e Freire (1987) que expõem a ideia de uma EAE direcionada para a transformação social e pautada também no diálogo, assim como o Instituto de Tecnologia Social (ITS) (2004), a Rede de Tecnologia Social (RTS) (2011), os quais ilustram conceitos referentes às TS. No campo empírico foram selecionados três projetos de TS relacionados à EAE, com a finalidade de analisar, categorizar e sinalizar como referências para discussão teórica. Ao efetuar o estudo, identificamos a necessidade da abordagem da temática no âmbito da prática social, de modo que haja maior aproximação entre os componentes teóricos da EA e das TS, já que é possível compreender estes fenômenos como prática de transformação social e também de formação humana.
The study of amphipods in rimstone pools of Akiyoshi-do Cave, Japan
Authors: Ando Kanato
Published: October 2019

Akiyoshi-do Cave is the largest show cave in Japan and has been recognised as a hotspot of cave animals due to their diversity in species. Human-induced alterations in the cave environment have been a significant concern catching the attention of tourists and managers. Previous studies indicated water quality alteration induced by tourism could affect the population densities of amphipods. However, no study went further than qualitative observation in terms of human impacts. This study targets two amphipods living in Akiyoshi-do Cave, Pseudocrangonyx akatsukai and Gammarus nipponensis and measures water characteristics in which they live. Results show that the population densities of the amphipods have decreased compared to the 1970s. Their living habitat has changed, probably induced by tourism.
Enquêter dans les hébergements et logements assistés. Émergence d’une théorie ancrée du chez-soi
Authors: Pichon Pascale
Published: October 2019

Cet article repose sur deux enquêtes sociologiques conduites entre 2009 et 2016 dans diverses villes françaises. Il propose une analyse compréhensive de l’expérience sociale du « chez-soi », là où on l’attend le moins : au sein des institutions d’hébergement et de logement assisté. Il propose une description analytique des significations de ce que recouvre, au regard des contextes situationnels observés, les quatre composantes d’une théorie ancrée du chez-soi : aménagements, attachements, appropriations et ancrages. La présentation de situations typiques documentées par l’observation ethnographique et par des entretiens croisés auprès des résidents et des intervenants sociaux met en évidence les restrictions des possibilités d’action hors de la sphère de l’assistance ainsi que l’éloignement de l’accès au droit au logement. L’analyse conduit in fine à penser plus largement le droit à habiter dans un milieu qui offre des appuis inconditionnels pour agir et investir l’espace d’un chez-soi.

Published: October 2019

A patient with acquired optic disc pit (ODP) maculopathy underwent vitrectomy with anterior capsule transplantation to the ODP and gas tamponade. Structural changes were evaluated by enhanced depth imaging optical coherence (OCT) tomography. During vitrectomy, the eye was confirmed to have preexisting posterior vitreous detachment. Postoperative OCT showed complete closure of the optic pit resulting in rapid absorption of subretinal fluid. The authors' observations suggest that the anterior capsule is a useful material for achieving optic pit closure. To the authors' knowledge, this is the first report describing application of the anterior capsule to the treatment of ODP maculopathy.

RIM DRIVEN PROPELLERS: OPTIMIZATION BASED DESIGN APPROACH USING RANS CALCULATIONS
Authors: Gaggero S
Published: October 2019

RIM driven propellers represent an unconventional, but underrated, propulsive solution which hydrodynamic design is still not obvious. In the last years, most of the attention has been devoted to the efficient coupling with electric motors, since only recently the development of permanent magnets allowed for the successful embedding of the driver directly inside the surrounding duct. From the hydrodynamic point of view, however, analysis and, in particular, design strategies are not yet ripe. In the light of the development of advanced design approaches for unconventional geometries, we propose a Simulation-Based Design Optimization tool based on RANS analyses of parametrically described geometries as a part of an automatic, multi-objective optimization loop. The SBDO is used to design a RIM driven propeller with an accelerating type duct, with improved performance simultaneously in terms both of efficiency and cavitation inception at different (design and quasi-bollard pull) functioning conditions.
PROPELLERS GEOMETRY MODELING THROUGH B-SPLINES SURFACES
Authors: Perez Fernandez Rodrigo , Pérez-Arribas Francisco
Published: October 2019

This work presents a new design methodology for modelling the blades of ship propellers using B-spline surfaces that are a standard tool in CAD and Naval Architecture software products.
Propeller blades of a ship are good examples of free form surfaces, designed specifically considering several parameters that control their performance. Traditional tools for surface design in CAD such as control point manipulation, are not appropriated for blade design, and the designers prefer to work with a collection of propeller parameters that ultimately represent its surface and that possess a clear hydrodynamic meaning.
This method uses common design parameters for the geometry of propellers and produces a final B-spline surface for the geometry of the blades that can be used for the visualization, calculations, and construction of the propeller.
The method starts with the definition of a 3D grid of points that form the propeller blades based on the 2D definition of a series of cross-sectional profiles at several radial locations. These 3D points consider the inclination and twist of the blades are given by rake and pitch angles, quite common in the design procedures, and also different propellers parameters such as skew and blade thickness distribution.
Propeller blades are very thin objects with great changes of curvature, and if standard B-spline techniques are used, they cannot be modelled well under a tolerance unless a large number of control points is used, producing very complex surfaces.
The method stresses the fitting of the blade's leading edge which has great effect on the propeller behavior and geometrically has a small curvature radius in comparison with the rest of the blades. The leading edge is difficult to reproduce with standard techniques.

Learning hands-on skills in Civil Technology ensures that learners are capacitated with skills that address socio-economic ills. However, most learners who have completed their studies in Civil Technology are still experiencing unemployment. The purpose of this chapter is to explore innovative teaching and learning techniques that Civil Technology teachers possess during hands-on practical lessons. This chapter used qualitative research approach using observation and interview data collection instruments. This chapter purposefully sampled nine teachers and 145 learners from Gauteng and Limpopo provinces of South Africa and used two frameworks, namely Roger's diffusion of innovativeness and 9E instructional model. The study found that teachers have various challenges in using innovative teaching and learning techniques such as digital technologies to enhance learners understanding of tools concepts. This chapter recommends training for teachers about how to execute hands-on lessons using 9E instructional model as a guide to innovative knowledge.
The Challenges of Work-Based Learning via Systemic Modelling in the European Union
Authors: Papakitsos Evangelos C. , Theologis Evangelos , Makrygiannis Panagiotis S.
Published: October 2019

While the skills mismatch is well documented in EU labour market, it renders work-based learning a plausible part of the answer to this problem. Yet, a number of issues demand handling before work-based learning is effectively utilized. Systems inquiry, through systemic modelling, constitutes a proper framework to facilitate a holistic study of such complex social phenomena. From a systemic perception, the complexity of social systems has prevented a holistic study. The descriptive power of systemic modelling allows for such a study that relates labour-market to dual education via apprenticeship. Thus, the respective systems are studied as a whole; the challenges arising are specified and the limitations of the solution are clarified. The application of apprenticeship in heavily industrialized countries can yield results, but it may fail in countries like Greece with a very different socio-economic environment. Still, some recommendations can be formed for a variant of apprenticeship more attuned to such cases.
Modeling Barriers in Green Procurement using ISM
Authors: Ezzati Amin , Jamejam Parivash , Bhatia Manjot Singh
Published: October 2019

Green procurement, a significant part of green supply chain management, plays a key role in implementing the green concept by considering the environmental issues. Due to increase in public awareness about environmental criteria, industries have been forced to consider environmental issues in their current production flows. Further, since the automotive industry has a direct impact on the environment, it is very beneficial to study the barriers that prevent this industry from implementing the green concept. Iran has had a considerable growth in the automotive industry in the last few decades and today owns and operates the largest automotive factory in the Middle East. In contrast, Canada as a leader in environmental issues does not have a large automotive industry, but is a country where some localized international companies have located small factories. The differences between these two countries make their comparison more valuable and noteworthy. This study investigates this comparison based on a structural modeling methodology known as interpretive structural modeling (ISM).

Authors: Zhang Zhong Hua , Sharifnia Ehsan
Published: October 2019

Risk management issues have been widely researched in areas such as system engineering, business management, financial planning, market research, and service industry. Many approaches have been proposed to reduce or minimize risks, maintain productivity or profitability in organizations. However, different risk management strategies are needed under different situations and different industries. In this chapter, the authors address the theme of risk management in supply chains. They begin by reviewing the metrics of supply chain performance, followed by design and development of supplier relationship management process, and a failure modes and effects analysis (FMEA)-based approach to identify and evaluate the potential risks in the process of commodity procurement. After analyzing the causes and effects of potential risks in procurement, they develop a strategic plan to monitor and control risk management and implement continuous improvement. A case study is provided for supplier selection and buyer-supplier relationship management.

Published: October 2019

Supplier selection is a common practice in industrial sector and is usually conducted by engineers and administrators. However, in the healthcare sector, supplier selection is less commonly studied. This chapter proposes a methodology that simplifies the selection of suppliers in hospitals. As case study, the authors propose an example in which they evaluate six potential suppliers as alternatives with five attributes. The proposed methodology integrates the nominal group technique (NGT) to weight the attributes and dimensional analysis to estimate an index of similarity to an ideal supplier. This index of similarity is obtained from the best nominal values of the attributes. This methodology can be easily applied; it is intuitive and friendly to inexpert users, since the evaluation can be performed using a traditional spreadsheet. Also, the proposal allows for the simultaneous evaluation of multiple attributes and can be used by hospital administrators themselves, which prevents hospitals from hiring external services.

Massive open online courses (MOOCs) have evolved in past decade and become one of the prominent parts of the higher education system. The MOOCs provided a promising platform to aspirants who wanted to study further to either enhance their educational status or learn new technologies. With the evolution of MOOC, many platforms started to offer such courses, and many of them are not free as these courses need to register with some nominal fee. The role and need of libraries come at this point for MOOC courses as the courses are bundled with corresponding study material. The print library needs to assist e-library so that it may be compatible with the MOOCs and corresponding resources. The technological shift from print to e-library has a great impact on e-learning followed by MOOCs; however, the issue of MOOC libraries and resources is yet to be resolved to ensure the availability to all the users. The chapter deals with the need of library for MOOCs, its structure and technology shift from print library to e-library, along with the differentiation between e-learning and MOOCs.
