Saberes das mães sobre o uso de broncodilatador em crianças com displasia broncopulmonar no domicílio/ Mothers' knowledge on the use of bronchodilator in children with bronchopulmonary displasia at home
Authors: Silva Taís Folgosa , Pacheco Sandra Teixeira de Araújo , Rodrigues Benedita Maria Rêgo Deusdará
Published: January 2018

O objetivo do estudo foi conhecer os saberes das mães sobre o uso de broncodilatador em seus filhos com displasia broncopulmonar (DBP) no domicílio. Estudo descritivo e exploratório, qualitativo. Utilizou-se a entrevista semiestruturada com 14 mães de crianças com DBP, atendidas em um ambulatório de pneumologia. Os dados foram submetidos à análise de conteúdo temática, sendo extraídas três categorias que foram interpretadas à luz das concepções teóricas de Paulo Freire para o cuidado familiar, a saber: Conhecimento das mães sobre a ação do medicamento; Sinais de alerta percebidos pelas mães para o uso do medicamento na criança; As reações percebidas pelas mães após o uso do medicamento, as quais mostraram que a maioria das mães consegue identificar as principais ações do broncodilatador. O esforço respiratório configura-se como sinal de alerta para as mães utilizarem a medicação; a respiração melhorada surge como sinal prevalente detectado por elas após o uso do broncodilatador. Conclui-se que a compreensão desses saberes é imprescindível à construção de ações que respondam às suas necessidades no cuidado medicamentoso a seu filho quando no domicílio.

Published: January 2018

Coastal area has a strategic value for the development of national economy and improving people's welfare. However, coastal area is also extremely vulnerable to environmental damage and destruction. Therefore, the need of sustainable management with regard to the dimension of ecological, economic, social and institutional is important. This research is aimed to overview the current condition of coastal area in the Madura strait and to formulate coastal management strategies in term of sustainable development. Multi Dimensional Scaling (MDS) method was used in this research. Five dimensions (ecology, economy, social, technology and institution) were measured. The results showed that in general, coastal management of Madura Strait was less to moderately sustainable. It means that coastal management of the area has given enough contribution for the community; however the condition of the environment should be supervised closely to provide continuous benefit for future economics of the region.
Preliminary Study on Stability Parameters of Semi-Displacement Ships
Authors: Hetharia Wolter R.
Published: January 2018

Semi-displacement passenger ships operate at the speed range of 19 to 23 knots or Froude number Fn of 0.50 to 0.75. Those ships need higher engine power to maintain their speeds. The efforts should be made to minimize their higher engine powers. Most experts worked to minimize the engine power for most merchant ships. In their works, the initial metacentric (GMO) at departure condition was taken as constraint to represent stability parameters. However, this is not a general case for semi-displacement passenger ships. In this study, a parent semi-displacement passenger was designed and modified. Stability parameters were computed and evaluated as required by the rules IMO-HSC. In addition, one existing high speed passenger ship was evaluated for stability evaluation as reference also. It was found that the stability parameters at large angles of inclination such as: weather criterion, angle of GZmaxand others are more critical compared to GM0. Also, the stability parameters when ship is at arrival condition are more critical compared to those at departure condition. The study resumed that the application of criterion GM0≥ 0.15 m at optimization process of semi-displacement passenger ships should be considered again for the future.

Experimental Analysis on Sinking Time of Littoral Submarine in Various Trim Angle
Authors: Sinaga Luhut Tumpal Parulian
Published: January 2018

A submarine must conform to Archimedes’ Principle, which states that a body immersed in a fluid has an upward force on it (buoyancy) equal to the weight of the displaced fluid, (displacement). Submarines are ships capable of being submerged. The history of submarines and their operation have largely revolved around being able to alter the density of the vessel so that it may dive below the surface, maintain a depth, and return to the surface as needed. The way modern submarines accomplish this task is to bring in and remove water from tanks in the submarine called ballast tanks. Ballast tanks fit into two categories: those used for major adjustment of mass (main ballast tanks); and those used for minor adjustments (trim tanks). The effect of each tank is plotted and this is compared with the changes in mass and trimming moment possible during operations using a trim polygon to determine whether the ballast tanks are adequate. On the water surface, metacentric height (GM) is important, whereas below the surface it is the distance between the centre of buoyancy and the centre of gravity (BG) which governs the transverse stability of a submarine.

Authors: Sujiatanti S.H. , Zubaydi Achmad , Budipriyanto A.
Published: January 2018

Recently various types of sandwich panel are applied for constructing bridge and ship structures. Sandwich panel is material that consists of lightweight core material and two metal faceplates. The application of sandwich panel in ship structures makes the structure less-complex and ship’s selfweight lighter because of the reduction of secondary stiffeners. This paper discusses sandwich panel that was fabricated using synthetic resin core material and two steel faceplates. This study is aimed to analyze stresses developed in the sandwich panel of 750 GT Ro-Ro ship car deck structure when it was subjected to the deck design load. The finite element analysis was carried out to obtain the stress distribution and maximum deformation on the car deck structures. The stress of the ship car deck constructed using conventional steel structure, i.e. steel plate and stiffener, was compared with the stress of the deck that was built using sandwich panel.

Published: January 2018

This paper is written as one of the records of MOP model developments. MOP model is a new creation model for re-analyzing accidents in maritime traffic system (MTS). MOP is an abbreviation from 4M Overturned Pyramid, where 4M is Man, Machine, Media, and Management. The MOP Model is a 3D view model, looks like thee sided inverted pyramid that has 4 corners representing 4M and 6 edges as line relation for corners. At this paper, MOP model has been developed until the last steps. There are 2 steps utilizing MOP model when re-analyzing accidents, namely Corner Analysis (CA) that resulting causative factors (CFs) as the first step, and Line Relation Analysis (LRA) that resulting causative chains (CCs) as the second step. To see how this step works, 20 ship collisions in Japanese MTS have been re-analyzed. In this research, MOP Model has been upgraded until the second step, namely Line Relation Analysis (LRA). The outcome of this step is causative chain (CC). The results is there is core causative chain that has several heads and tails. However, most of the causative factor (CF) that perform CC are classified in Man Factor, especially improper look-out.

Published: January 2018

Most of the artificial reefs that have been developed in the world are the concrete structure. Regarding economical and practical consideration of artificial reefs, Indonesian government - Ministry of Marine Affairs and Fisheries - has proposed a new material to make an artificial habitats including artificial reefs made from polypropylene plastics (PP). However, diminishing approximately 80% of the weight structure compare to concrete structure has created new challenges to maintain the underwater structure with similar function. Moreover, the use of less weight material for artificial reefs structure will have impact on the structure responses.The structure responses due to sea bottom current and tidal stream velocity have been evaluated at several conditions. Dynamic pressure calculation was applied gradually as external load from a simple part to whole complex structure. Stresses and strains occur at some nodes as the structure critical area, within the same time frame, displacement of its elements describe physical characteristic response. Boundary conditions was encastred the sinker- bottom structure (U1 = U2 = U3 = UR1 = UR2 = UR3 = 0). In conclusion, for input of sea bottom current velocity u = 0.2 m/s the results for maximum stress are below the material’s yield stress hence its elasticity is relatively adequate to prevent permanent deformation. The result also showed some critical part of the structure that has high value on stress should be consider as the current velocity increase. Moreover increasing input and frontal area will significantly affect the drag force which will add load on the structure.

Published: January 2018

This paper describes a production process for experiment and finite element method (FEM) analysis of cold forming of SUS304 pipe. These large diameter pipes such as φ114.3 mm are used for a plant as a flow channel of gas and liquid. The connection of pipes are generally welded at the plant. However, the other connecting method are required from a viewpoint of making the plant environment worse by welding. Therefore, flaring process of large diameter pipes were proposed. This flaring process is one of a method of pipe flange forming. The formed pipes were connected used with loose flange. Flaring process was generally hot process, thus it has some problem such as becoming complex of forming machine and accuracy of dimension. In this study, cold flaring process of SUS304 pipe was proposed to satisfy these requisitions. Experiment and FEM analysis of cold flaring process were performed to clarify the optimum forming conditions for the flat length of connecting surface such as a diameter of punch, punch stroke and taper angle of dies. As a result, a gap between punch and die was needed to match the pipe wall thickness.

Published: January 2018

Electro-Discharge Machining (EDM) is very popular for machining high-strength conductive materials for aerospace and automotive application. These machining involve a range of processing parameters. In order to optimize these for the best performance, a trade-off has to be decided for the responses achieved through machining. Conventional algorithms have long been replaced by advanced optimization algorithms. Performance of meta-heuristic algorithms in relation to traditional deterministic approaches for multi-modal, non-linear engineering problems is very promising in recent days. In this paper, a multi-objective optimization approach is applied using a population-based meta-heuristic algorithm called Passing Vehicle Search (PVS) for optimizing process parameters of various mathematical models formulated by different authors. Different approaches depending on case have been adopted for formulating the multi-objective PVS algorithm and pareto front is obtained for each case to extract the desired results. The performance of multi-objective PVS is compared with different intelligent computing models employed in prior studies and better results are shown in case of former. This approach can be extended to various mathematical models besides those covered in the paper to obtain better optimization results.

Published: January 2018

Strip casting of Al-40%Sn-1%Cu, which is an aluminum alloy used for sliding bearings, was attempted using an unequal diameter twin roll caster. The conditions required to cast sound strips, including the roll speed, molten temperature, roll load, solidification length, melt head, and use of an upper plate, were investigated. The roll load required to make a stable strip surface was 0.01 kN/mm, and the porosity was minimum when the solidification time was less than 0.6 s. The solidification time was controlled by the roll speed and the solidification length. The casting temperature must be set below 670°C to properly solidify the molten metal, and the metal microstructure became finer as the melt head decreased.

Published: January 2018

Among the problems encountered when roll casting Al-405Sn-1%Cu, which is an aluminum alloy used for sliding plate bearings in large maritime diesel engines, are solidified chips embedded in the strip and scratch marks on the lower roll contact surface. In this study, three different improvement methods aimed at eliminating these particular defects—vibrating the side plates and back dam plate, adding a vibrating plate, and varying the casting conditions—are examined. Vibrating the side plates and dam plate was found to be effective for preventing these defects, while adding another vibrating plate was comparatively less effective. As for casting conditions, it was also determined that the occurrence of these defects could be reduced by increasing the roll speed, and that the molten metal casting temperature had little or no influence on defect formation.

Authors: Kim Jee Sang , Lee Sang Hyun , Choi Jung Wook
Published: January 2018

Epoxy coated reinforcements have been used extensively in bridge decks and substructures to protect against corrosion brought on by de-icing salts or marine environments. They need longer development lengths because of poor bond to concrete and special treatments on sites due to vulnerability of damage during transportation, storage and bending process. A new method of pre-heating of reinforcement before coating process using an IGBT(Insulated Gate Bipolar Transistor) control was applied to improve the bond of epoxy coating to reinforcements. In this paper, the bond-slip properties of newly developed epoxy coated bars are investigated and compared to those of black bars. The direct pull out test according to EN Standard was used with varying the diameters of reinforcements. The experimental results show that the new process is very efficient in increasing bond capacity of epoxy coated bars to concrete comparing those of traditional ones.

Published: January 2018

Nowadays, plant biomaterials have been used in several types of industries for related purposes for example energy and electricity production, as our world is facing energy shortage problems. In this paper, the combustion behavior of a typical plant biomaterial, corn cob, was investigated using TG-DSC technique. Combustion experiments were conducted from room temperature to 900 °C at three heating rates of 10, 20 and 30°C/min in air atmosphere. It is observed that the process can be divided into three stages: dehydration (25°C-150°C), pyrolysis (150°C-380°C) and combustion (above 380°C). Besides, ignition and burnout temperature were investigated based on DSC profiles. Finally, two model-free methods (FWO and KAS) were adopted to perform the kinetic analysis for combustion reaction process. It is found that activation energies values against conversion rate present a rising trend (from about 172.40 KJ/mol to 326.95 KJ/mol) in the pyrolysis stage, while an opposite tendency was observed in the combustion stage (from about 365.55 KJ/mol to 202.86 KJ/mol), indicating that corn cob combustion is a complex process and relatively complex reaction schemes should be adopted to describe its combustion. It is anticipated that our current work could be helpful in providing reference to the design of energy conversion facilitates.

Published: January 2018

Chitosan membrane (Ch) has mechanical stability, physical, and chemical low thus limiting their application to a variety of purposes. Therefore in this study examined the effect of adding silica and polyethylene glycol (PEG) on the mechanical properties, physical, and chemical chitosan-based membranes. A source of silica used is tetraethyl orthosilicate (TEOS). Composite membrane Chitosan-silica-PEG (Ch/Si/P) was prepared using the sol-gel process and characterized morphology, crystallinity, and changes in functional groups. In general, the addition of silica in the preparation of composite membrane Ch/Si, increases tensile strength, Young's Modulus, pore size distribution, as well as lower percent Elongation but does not affect the crystallinity and the change of functional groups on the membrane. The addition of PEG on manufacture composite membrane Ch/Si/P, increases the percent Elongation, Young's Modulus decrease and decreased pore size distribution, but does not affect the crystallinity, as well as to changes in the functional groups on the membrane. The results showed that membrane with a mass ratio of chitosan/silica/PEG of 1:0.7:0.5 have a maximum percent Elongation and the minimum Young's Modulus.

Published: January 2018

There are many methods describing defects induced by ion implantation, but none are capable of describing it quantitatively. In order to solve this problem, we studied the magnetic change of silicon carbide (SiC) after ion implantation, and found that even if the implantation intensity and defects were increased, we found that all samples have the same paramagnetic background. In this paper, we use the paramagnetic characteristics shown by part of the defects to characterize the degree of defects. We studied how to characterize the concentration of the defect, using the Brillouin function to fit the data, validated the experimental results and analyzed the relationship between paramagnetic center concentration and defects.

Published: January 2018

An amoprphous and nanocrystalline ribbon is produced applying the technology of rapid molten metal quenching. The chemical composition of the alloy is required to contain elements ensuring the amorphous structure formation in the course of quenching. A great number of various chemical elements in amorphous and nanocrystalline alloys contribute to the complex process of the structure formation in the course of heat treatment of the amorphous precursor. After heat treatment, the structure of the soft magnetic material can remain amorphous or partially crystallized or nanocrystalline. The results of an investigation into the melts’ property of iron-based amorphous and nanocrystalline alloys are presented in the paper. The structure has been shown to influence mechanical properties of the material in preparing the melt before casting.
Effect of Tool Path Parameters on Part Porosity in Fused Filament Fabrication of Poly(Ethylene-co-Trimethylene Terephthalate)
Authors: Bail Robert
Published: January 2018

Poly(ethylene-co-trimethylene terephthalate) is an engineering material that has recently gained attention for use in fused filament fabrication (FFF). Although the properties of this thermoplastic are well suited for this process, the porosity of the components made remains a barrier to wider use of this approach in the additive fabrication of tight components for medical and food applications. This study investigated the effects of four tool path parameters of the FFF process – road width, air gap, layer thickness, and outer contours – on the void fraction in the structures made. It was revealed that the porosity was reduced from above 9% to below 2% when the extrusion rate was increased from initially 5.00 mm3/s to at least 5.75 mm3/s. A similar outcome was observed when a negative air gap between two adjacent strands of -15% or less was applied. In addition, these results were obtained without extending the print times. By contrast, altering the layer thickness and number of contours had only marginal or no effects on part porosity.
CD40 Mediates Maturation of Thymic Dendritic Cells Driven by Self-Reactive CD4+ Thymocytes and Supports Development of Natural Regulatory T Cells
Authors: Oh Jaehak , Wu Nan , Barczak Andrea J. , Barbeau Rebecca , Erle David J. , Shin Jeoung-Sook
Published: January 2018

Thymic dendritic cells (tDCs) play an important role in central tolerance by eliminating self-reactive thymocytes or differentiating them to regulatory T (Treg) cells. However, the molecular and cellular mechanisms underlying these functions are not completely understood. We found that mouse tDCs undergo maturation following cognate interaction with self-reactive CD4+ thymocytes and that this maturation is dependent on CD40 signaling. Ablation of CD40 expression in tDCs resulted in a significant reduction in the number of Treg cells in association with a significant reduction in the number of mature tDCs. In addition, CD40-deficient DCs failed to fully mature upon cognate interaction with CD4+ thymocytes in vitro and failed to differentiate them into Treg cells to a sufficient number. These findings suggest that tDCs mature and potentiate Treg cell development in feedback response to self-reactive CD4+ thymocytes.
Physician Beliefs about the Meaningful Use of the Electronic Health Record: A Follow-Up Study
Authors: Emani Srinivas , Ting David , Healey Michael , Lipsitz Stuart , Karson Andrew , Bates David
Published: January 2018

Background There is continuing interest in how physicians are responding to the meaningful use of the electronic health record (EHR) incentive program. However, little research has been done on physician beliefs about the meaningful use of the EHR.

Objective This study aims to conduct a follow-up study of physician beliefs about the meaningful use of the EHR.

Methods Online survey of physicians at two academic medical centers (AMCs) in the northeast who were participating in the meaningful use of the EHR incentive program and were using an internally developed EHR was conducted.

Results Of the 2,033 physicians surveyed, 1,075 completed the survey for an overall response rate of 52.9%. Only one-fifth (20.5%) of the physicians agreed or strongly agreed that meaningful use of the EHR would help them improve quality of care, and only a quarter (25.2%) agreed or strongly agreed that the meaningful use of the EHR would improve the care that their organization delivers. Physician satisfaction with the outpatient EHR was the strongest predictor of self-efficacy with achieving stage 2 of the meaningful use of the EHR incentive program (odds ratio: 2.10, 95% confidence interval: 1.61, 2.75, p < 0.001). Physicians reported more negative beliefs in stage 2 than stage 1 across all belief items. For example, 28.1% agreed or strongly agreed that the meaningful use of the EHR would decrease medical errors in stage 2 as compared with 35.9% in stage 1 (p < 0.001).

Conclusion Only one-fifth of the physicians in our study believed that the meaningful use of the EHR would improve quality of care, patient-centeredness of care, or the care they personally provide. Primary care physicians expressed more negative beliefs about the meaningful use of the EHR in stage 2 than in stage 1. These findings show that physicians continue to express negative beliefs about the meaningful use of the EHR. These ongoing negative beliefs are concerning for both implementation and policy.

Background Platforms like tranSMART assist researchers in analyzing clinical and corresponding omics data. Usability is an important, yet often overlooked, factor affecting the adoption and meaningful use. Analyses on the specific needs of translational researchers and considerations about the application of such platforms for education are rare.

Objectives The aim of this study was to test whether tranSMART can be used in education and how well medical students and professional researchers can handle it; to identify which kind of translational researchers—in terms of skills, experienced limitations, and available data—can take advantage of tranSMART; and to evaluate the usability and to generate recommendations for improvements.

Methods An online-based test has been done by medical students (N = 109) and researchers (N = 26). The test comprised 13 tasks in the context of four typical research scenarios based on experimental and clinical data. A web questionnaire was provided to identify both the needs and the conditions of research as well as to evaluate the system's usability based on the “System Usability Scale” (SUS).

Results Students and researchers were able to handle tranSMART well and coped with most scenarios: cohort identification, data exploration, hypothesis generation, and hypothesis validation were answered with a rate of correctness between 82 and 100%. Of the total, 72.2% of the teaching researchers considered tranSMART suitable for their lessons and 84.6% of the researchers considered the platform useful for their daily work; 65.4% of the researchers named the nonavailability of a platform like tranSMART as a restriction on their research. The usability was rated “acceptable” with a SUS of 70.8.

Conclusion tranSMART is potentially suitable for education purposes and fits most of the needs of translational researchers. Improvements are needed on the presentation of analysis results and on the guidance of users through the analysis, especially to ensure the compliance of the analysis with the requirements of statistical testing.

Published: January 2018

We present  three  case  studies  illustrating  the  virtual  reproduction  of  caves  that  belong  to  the  most  important  artistic ensemble of the Paleolithic from Bizkaia (Spain): Benta Laperra, Askondo and Lumentxa. The complex morphology of the cavities, the fineness of their engravings and the poor definition of their paintings imply technical difficulties to achieve faithful reproduction of their geometry and appearance. The methodology applied in these caves, based on a combination of photogrammetric and surveying techniques, allows the creation of a complete virtual replica, without shadow zones and a detailed reproduction of their engravings and paintings. At the same time, this replica has given rise to a type of technical documentation that very faithfully and objectively facilitates the analysis and interpretation of the cave. On the one hand, series  of  longitudinal  and  transverse  sections  have  been  generated, extracting  information  of  the  cut  profile  and  the projection of the surfaces through orthoimages of elevation-section with a level of resolution of 2 mm per pixel, equivalent to a scale of representation 1/10. In addition, the georeferencing of the caves has allowed the research team to generate cartography of elevations of floor and ceiling by means of contour lines and to overlap the cartography of the National Geographic Institute (IGN) to measure the distance that separates the ceiling of the cave from the external surface. It can be used to detect critical points that must be taken into account in case of possible actions in forestry or infrastructure projects. Finally, these virtual replicas allow the dissemination of a wealth in detail, through new interactive methods of visualization and virtual reality. In conclusion, the presented methodology means an advance with respect to the existing techniques thus providing solutions for both technical and informative applications.

The Impact of the Internet on Saudi Arabia Travel Agencies
Authors: Alolayan Fahad Saleh
Published: January 2018

This study investigates the impact of the Internet revolution on travel agencies on Saudi Arabia’s travel agency market. A reliable and valid three-part questionnaire was developed: the first part collects the basic information on the travel agencies; the second part examines the extent to which travel agencies use the benefits of the Internet for their operations; the last part measures the real impact of the internet on travel agencies with four dimensions. A sample of 50 travel agencies fully participated in this study. The descriptive data of the sample indicates that the travel-agency industry in Saudi Arabia is still very small; more than 50% of the agencies operate with less than five employees in one or two branches only. More than 55% of the agencies have less than four years of experience and relatively small capital. In addition, the descriptive data reveals that 72% of the agencies in the sample do not have their own websites, and only 4% of the agencies have websites with features that complete customers’ transactions without human involvement. The main results assure the importance and the benefit of using the Internet for Saudi Arabia travel agencies; however, they have not yet used most of its advantages. Moreover, they do not see any threat or negative impact to their business from the Internet. A number of recommendations have been provided to this industry, such as using the power of the Internet as a global competition tool, and the opportunity of a major emergence among travel agencies in this market.
How to Manage Issues Relating to the Use of Trial Experts: Standards for the Introduction of Expert Testimony through Judicial “Gate-Keeping” and Scientific Verification
Authors: Hunter, Jr. Richard J. , Shannon John H. , Amoroso Henry J.
Published: January 2018

This paper considers issues relating to the introduction of expert testimony in both civil and criminal cases in the American legal system. The paper reviews the Daubert Rule and the standards governing the admissibility of expert testimony in relation to the requirements of peer review and the use of a recognized “scientific method.” A number of federal cases will be considered which have attempted to refine and apply the Daubert Rule in a variety of factual circumstances where expert witnesses have been called on to offer their testimony and opinions at various stages of the legal process.
A transexualidade na literatura científica das ciências da saúde
Authors: Salles Débora Gomes , Gonçalves Jéssica Dos Santos , Araujo Luciana Danielli de
Published: January 2018

Introdução: O trabalho discute a visibilidade dos estudos científicos sobre transexualidade no campo da Saúde. Objetivos: O estudo questiona de que forma a transexualidade é abordada no campo na atualidade, tendo como margem temporal o período 2014-2016. Metodologia: A análise de domínio, proposta por Birger Hjørland e Hanne Albrechtsen, foi adotada, como abordagem teórico-metodológica, para o reconhecimento do grupo social transgênero como uma comunidade discursiva. A coleta de dados foi realizada na base LILACS, gerenciada pelo Centro Latino-Americano de Informação em Ciências da Saúde (BIREME), a partir dos dados descritivos (centrando-se no título dos artigos), tendo como limitador do levantamento o(s) termo(s) “transexual(is)”. Resultados: Foram recuperados 22 (vinte e dois) documentos no período. A partir destes, foram identificados para análise os seguintes metadados, autor, título, método e população de estudo utilizados, descritor, ano de publicação, sendo consideradas para o estudo, como centrais, os elementos “método” e “temacidade” (retirada a partir dos descritores). Após a análise do corpus, constatou-se que os métodos adotados para abordar o tema são: estudos de narrativa; revisões de análises quali e quantitativas, estudos observacionais, revisões teóricas; análises de conteúdo, estudos comparativos, análises de discurso, revisões sistemáticas, entre outras citadas ao longo deste estudo. As principais ocorrências temáticas identificadas a partir dos descritores foram: pessoas, readequação, gênero, identidade, hormônios e saúde. Conclusões: Dentro dos limites da extensão e horizontalidade dos dados, depreende-se dos resultados que as Ciências da Saúde na América Latina e Caribe ainda estudam a transexualidade com foco na patologização dos indivíduos, principalmente a partir das representações manifestadas pelas noções “readequação” e “hormônios”.

Authors: Rodas Cecilio Merlotti , Vidotti Silvana Aparecida Borsetti Gregório
Published: January 2018

Introdução: Na era de intensa produção de informações na qual se vive, as interfaces humano-computador podem ter um impacto considerável sobre o sucesso de um produto. É por meio das interfaces que as pessoas acessam as informações e nesse contexto o usuário sempre deve ser considerado. Tendo em vista que o acesso às Tecnologias de Informação e Comunicação tem sido feito cada vez mais por pessoas menos especialistas, como crianças e idosos, as interfaces precisam se tornar gradativamente mais intuitivas e serem capazes de atrair a atenção de seus usuários. Nesse contexto, estudos em User Experience mostram que certas tecnologias, como o Eye Tracking, são capazes de capturar camadas extras de dados e assim permitir uma melhor compreensão do comportamento das pessoas ao acessarem informações digitais. Objetivo: Nos testes buscou-se identificar se os usuários poderiam ser influenciados pelas duas diferentes tarefas dadas, uma com e outra sem apelo emocional. Metodologia: Neste trabalho foram realizados testes com usuários sobre a página de resultados do mecanismo de busca do Google, utilizando a tecnologia de Eye Tracking, procurando estimular o apelo emocional em um dos dois grupos participantes. Resultados: Os resultados surpreenderam ao mostrar que os links contidos nas páginas de resultados do Google, que apresentavam Rich Snippets, foram capazes de influenciar o comportamento dos participantes, independente da tarefa. Conclusão: Esses resultados revelaram o impacto do elemento Rich Snippet na experiência do usuário ao buscar informações na interface do Google.
Métodos de análise de assunto em fotografias: estudo no âmbito do ensino da representação da informação
Authors: Simionato Ana Carolina
Published: January 2018

Introdução: O documento fotográfico é considerado por seu valor histórico e por seus elementos próprios de realidade direta que são transmitidos pela sua sintaxe visual. Propõe-se a reflexão de como os métodos de análise de assunto em fotografias devem fazer parte da composição do ensino da representação nos cursos de Biblioteconomia e Ciência da Informação na Universidade Federal de São Carlos (UFSCar).  Objetivo: É objetivo deste trabalho apresentar um panorama das principais orientações para a atribuição do valor do metadado de assunto no tratamento de fotografias, inserido ao âmbito do ensino na graduação de Biblioteconomia e Ciência da Informação. Metodologia: O levantamento bibliográfico realizado abordou orientações acerca da representação de fotografias, subsidiando a natureza teórica, exploratória e qualitativa do trabalho. Resultados: Os resultados mostram que as características de assunto apresentam uma gama de possibilidades e que, mesmo assim, não retiram a subjetividade de uma imagem. Conclusões: Considera-se que a utilização dos instrumentos e orientações para o conteúdo aumenta a consistência dos metadados de assunto para os sistemas de localização, acesso, uso e reuso de fotografias, em bancos de dados, catálogos e outras formas de armazenamento imagético.
