Authors: Khudeyer Raidah S. , Alabbas Maytham , Radif Mustafa
Published: April 2020

Nowadays, optical character recognition is one of the most successful automatic pattern recognition applications. Many works have been done regarding the identification of Latin and Chinese characters. However, the reason for having few investigations for the recognition of Arabic characters is the complexity and difficulty of Arabic characters identification compared to the others. In the current work, we investigate combining multiple machine learning algorithms for multi-font Arabic isolated characters recognition, where imperfect and dimensionally variable input charactersare faced. To the best of our knowledge, there is no such work yet available in this regard. Experimental results show that combined multiple classifiers can outperform each individual classifier produces by itself. The current findings are encouraging and opens the door for further research tasks in this direction.

Published: April 2020

Human skin detection, which usually performed before image processing, is the method of discovering skin-colored pixels and regions that may be of human faces or limbs in videos or photos. Many computer vision approaches have been developed for skin detection. A skin detector usually transforms a given pixel into a suitable color space and then uses a skin classifier to mark the pixel as a skin or a non-skin pixel. A skin classifier explains the decision boundary of the class of a skin color in the color space based on skin-colored pixels. The purpose of this research is to build a skin detection system that will distinguish between skin and non-skin pixels in colored still pictures. This performed by introducing a metric that measures the distances of pixel colors to skin tones. Results showed that the YCbCr color space performed better skin pixel detection than regular Red Green Blue images due to its isolation of the overall energy of an image in the luminance band. The RGB color space poorly classified images with wooden backgrounds or objects. Then, a histogram-based image segmentation scheme utilized to distinguish between the skin and non-skin pixels. The need for a compact skin model representation should stimulate the development of parametric models of skin detection, which is a future research direction.

A Hybrid Global Local Adaptive Particle Swarm Optimization-Based Support Vector Machine Model for Human Facial Authentication
Authors: Hussein Salam Allawi , Mahmood Alyaa Abduljawad , Dohan Mohammed Iqbal
Published: April 2020

A new facial authentication model called global local adaptive particle swarm optimization-based support vector machine, was proposed in this paper. The proposed model aimed to solve the problem of finding the preeminent parameters of support vector machine in order to come out with a powerful human facial authentication technique. The conventional particle swarm optimization algorithm was utilized with support vector machine to explore the preeminent parameters of support vector machine. However, the particle swarm optimization support vector machine model has some limitations in selecting the velocity coefficient and inertia weight. One of the best approaches, which is used to solve the velocity coefficient problem, is adaptive acceleration particle swarm optimization. Also, the global-local best inertia weight is used efficiently for selecting the inertia weight. Therefore, the global local adaptive particle swarm optimization-based support vector machine model was proposed based on combining adaptive acceleration particle swarm optimization, global-local best inertia weight, and support vector machine. The proposed model used the principal component analysis approach for feature extraction, as well as global local adaptive particle swarm optimization for finding the preeminent parameters of support vector machine. In the experiments, two datasets (YALEB and CASIAV5) were used, and the suggested model was compared with particle swarm optimization support vector machine and adaptive acceleration particle swarm optimization support vector machine methods. The comparison was via accuracy, computational time, and optimal parameters of support vector machine. Our model can be used for security applications and apply for human facial authentication.
Islamic Law and National Cultures Impact on Modern Funeral Services Buying Ethical Perception and Behavioral Intention
Authors: Subarsyah Subarsyah , Kurniasari Florentina
Published: April 2020

The purpose of this paper is to analyze the impact of Islamic law and national cultures on the ethical perceptions and behavioral intentions of Muslim Indonesians in buying modern funeral services. A questionnaire was distributed among Muslim respondents who were doing their routine weekly Friday prayers in Sunda Kelapa, one of biggest mosques in Central Jakarta. Based on a total sample of 103 responses, structural equation modeling was used to test the research hypotheses. This research used the theory of reasoned action proposed by Ajzen to analyze behavioral intentions. Since the behavioral intentions were influenced by the ethical perceptions, the Hofstede national culture was deemed to play a significant role. The data analysis further suggested that the behavioral intentions in buying modern funeral services were strongly influenced by Islamic law (MUI Fatwa), Indonesia culture dimensions, and the ethical perceptions among Muslim Indonesians. Both Islamic law and Indonesian national culture (as a collectivist country) play a significant role in creating ethical perceptions and influence Muslim behavioral intentions in regard to buying modern funeral services.

Published: April 2020

A mobile wallet is a part of financial technology products and it is still in the infant stage in Malaysia. This study applied 2 theories such as Theory of Reasoned Action and Theory of Acceptance Model. The research objectives of this paper are 1) to investigate the factors influencing consumers’ behavioural intention to accept of the mobile wallet in Malaysia, 2) to analyze the relationships between perceived usefulness, perceived ease of use, perceived security, social influence, price value, social media, brand image, and behavioural to accept the mobile wallet, and 3) to examine the relationship between the behavioural and intention to accept of the mobile wallet in Malaysia. Quantitative data analysis was employed in this study. The results implied that perceived usefulness, perceived ease of use, social influence, and brand image have a significant relationship on the consumers’ behavioural to accept of the mobile wallet, and also the consumers’ behavioural has a significant relationship on the intention to accept mobile wallet. Considerably, the mobile wallet companies can formulate appropriate marketing decisions in designing a more personalized mobile wallet to Malaysian consumers and protect the benefits of consumers’ secured digital payment to motivate mobile wallet acceptance.
Geotechnical Analysis of Teeb Weir Foundation Soil Stability Against Seepage Effects
Authors: Al-Saedi Riaed Saee Jasim
Published: April 2020

The steady state seepage analysis is used to compute the factor of safety against piping for Teeb weir in the eastern part of Maysn. Teeb weir is a one of a swarm of hydraulic structures that were suggested and designed to reduce flooding risk in the Teeb area, and to work as a water harvesting system to recharge ground water in the area. The geotechnical engineering map is drawn to analysis the soil properties and estimate the suitability of the soil to support foundation of the weir body and downstream reservoir. SEEP/W software is used to solve the water seepage model underneath the weir foundation. Only the saturated model is selected to compute the factor of safety against vertical piping and to denote the zone of potential piping erosion. The model results show that the stability is critical and that there is a high possibility of failure expected, especially in the downstream zone.

Authors: Saleh Haeruddin , Abubakar Herminawati , Suriani Seri
Published: April 2020

The natural resources in Bulukumba district are readily available, but they are not optimally managed. Thus, the current economic growth of 5.05% is not high compared to other areas in South Sulawesi. Therefore, there is a need to increase the regional economic growth investment from both domestic and overseas sources. The purpose of this research is to determine the potential of the area and decide how the policy for supporting investments and strategies can be done to improve investment in the region. This research, using qualitative descriptive research methods, is a study conducted to determine the value of self-variables, either one or more variables (independent) without making comparisons or linking them with other variables.Qualitative research is a systematic scientific study of the parts and phenomena. The research results are known to the potential area with high competitiveness consisting of the agricultural, fisheries, and tourism sectors. The tourism sector is one of the flagships owned by Bulukumba. There are some tourism products that are superior to the area that are not owned by other regions such as the craft of “Phinisi” boat making as a product of the community culture and the culture of "amma toa" in kajang that has not been well managed. Bulukumba can be developed with clear rules so investors can enter and cultivate potential there in order for it to increase regional economic growth to a rate of 7.5%. Moreover, investment development strategy is the provision of convenience in terms of business licenses and the promotion of the area’s potential using technology.
The Effect of the Beat Phenomenon on the Oscillating Water Column Device
Authors: Jasron Jahirwan Ut , Soeparman Sudjito , Yuliati Lilis , Darmadi Djarot B.
Published: April 2020

The oscillating water column is the most natural type of wave energy converter because of its simple mechanical structure. To achieve maximum energy conversion efficiency, the incident waves and the natural frequency of the device’s construction have to be in resonance. This paper discusses the beat phenomenon as a form of resonance and several factors that allow the beating to occur, namely the relative depth of the wave (h/L) and the ratio of the submerged front wall length to the water depth (a/h), and their effect on oscillating water column efficiency. The test results show that the beat phenomenon occurs in the wave period T = 1.7 s, with a maximum efficiency of 22.12% achieved at conditions h/L = 0.114 and a/h = 0.4.
Water Treatment Ability of CuO-ZnO Nanocomposites Synthesized by Laser Ablation and Anodization Techniques
Authors: Rashid R.B. , Hussain D. H. , Mahmood R. S.
Published: April 2020

The article describes new ideas about the differences in the pollutant-removal ability of nanocomposite prepared by two methods. Nanocomposites (CuO-ZnO) can be simply synthesized chemically in aqueous solution by anodization method or physically by a laser ablation method. Therefore, both anodization and laser ablation methods were investigated. UV-visible spectra, atomic force microscopy AFM, and transmission electron microscopy TEM were used for characterizations. Results indicated that nanoparticles prepared by laser ablation had less diameters (74nm) than that prepared by anodization method. TEM images showed that particles produced by laser ablation method were homogeneous and core-shell structures with no aggregation, but that produced by anodization method were aggregated. This result could suggest that the laser ablation method is specifically preferable. The nanoparticles diameters ranged from 10–17 nm, which may confirm that ZnO nanoparticles have successfully shielded the CuO nanocore. Results also indicated that these synthesized nanocomposites have actively removed pollutions from water samples of Diyala River. There is a clear difference between the activity of laser ablation nanocomposite and that of anodization composite. Laser ablation nanocomposite needs less than 60 min to treat 85% of water pollution, but with anodization composite, even after 90 min. the water sample is still polluted (30% treated). Laser ablation nanocomposites give high performance of removing pollutants.

Architectual/landscape complex „Uroczysko Zaborek“ as an example of the preservation of historic wooden architecture
Authors: Landecka Halina
Published: April 2020

The historic wooden structures are exposed to specific risks arising from the nature of material used, in particular: increased sensitivity to moisture/active biological agents and flammability. The worst preservation conditions are present in unhabited, unused and unsecured structures. Uroczysko Zaborek in Janow Podlaski is an interesting example of private „resort of rural culture“ in which the intention of preservation of wooden buildings came in pair with its contemporary use. The resulting architectual/landscape complex consisting of translocated and preserved structures from the Lublin area is used as multifunctional tourist resort carefully situated in the natural and surroundings of Podlasie region: river, forests and picturesque fields. Good transport links with nearby cities Janow Podlaski and Biala Podlaska are additional advantages. Complex covers an area about 70 hectares of free composition based on the course of four internal roads. Architectural objects: old cottages, farm buildings, manor house, vicarage, windmill, church have been adapted either for museum or tourist accommodation/catering. Although Zaborek has not been granted a formal museum status, it plays an important educational role by promoting the cultural heritage of the countryside through the active protection of its tangible and intangible values. In 2013 Uroczysko Zaborek were amount the five awarded places in an international competition EDEN (European Destinations of Excellence) as an interesting place to promote rural tourism and preserve national heritage.
For survival of heritage. Multicultural temples of south-eastern Poland – history written in wood
Authors: Wrana Jan , Fitta-Spelina Agnieszka
Published: April 2020

South-eastern Poland - the Border region -for centuries was a place of coexistence of cultures, languages and religions. The symbol of multiculturalism and the remains of the temples are among others many faiths – Catholic churches, Orthodox churches, Protestant churches and Jewish synagogues, a large percentage built of wood - especially in rural areas. Once the pride and glory of his followers, now - due to changes in religious structure of the region, often as a result of tragic events - most likely to change destiny or fall into ruin and deteriorate. Their protection and maintenance is necessary not only because of its architectural value, but above all in order to preserve the memory of those who have already passed away.

In this article, authors look at the current situation of wooden temples of eastern Polish region (both Orthodox and Catholic and Greek Catholic), in some cases more accurately by analyzing their past and considering opportunities for the future. Authors also speak about contemporary ways of their protection in terms of formal and legal, and the ability to preserve - through revitalization, adaptation and change functions.
Vernacular, which means? Semantic remarks as side notes on the main topic of the conference
Authors: Rytel Grzegorz
Published: April 2020

The term vernacular referring to art and architecture was used for the first time in England in the middle of the nineteenth century. Numerous definitions have been created since the first Conference on Vernacular Architecture in Plovdiv in 1975. Still none of them defines the term utterly. Discrepancies in its interpretations could also be seen in attempts to translate the term coined in English and deriving from Latin.

The right meaning of the term vernacular architecture shall be searched in its linguistics – etymology and semantics. In some works on vernacular architecture there are references to a word derivation - the primary Latin term verna. The word describes a slave born in a house of their master – well-known, familiar to all household members, trustworthy, close, but at the same time meaningless (faceless), withdrawn, ‘invisible’, someone who belongs in fact neither to the household nor to the family. One might say vernacular architecture does not look up to itself in the mirror; its attribute is self-unconsciousness. Architecture remains vernacular – anonymous, day-to-day, satisfying the most basic needs, becoming increasingly better with generations in models recognisable by their users – as long as it is not tempted by interpreting sophisticated, modern models of monumental architecture; as long as it does not compete to be distinctive. And maybe therefore in this regard it is architecture without an architect.
The diversity of modern forms of preservation of rural and small towns’ wooden architecture in Poland
Authors: Szot-Radziszewska Elżbieta
Published: April 2020

In this paper I discuss the modern forms of preservation of wooden historical monuments, included in the legal framework, such as protection via an entry in the records or monuments’ list, protection in open-air museum, being declared historical monument, protection via creation of a cultural park. I am pointing out the tragic state of the protection and conservation of the resources of this part of heritage. I discuss in wider scope the idea of open-air museum in Poland and the specificity of preservation of wooden monuments in the open-air museums as being the most rational and effective so far. I show positive protection examples via making use of and adaptation of the monument to the new function- cultural, educational or museum. I also emphasize the role of education and society participation in the protection of rural architecture. The wooden architecture is only 11% of all monuments registered in monuments’ list. In this situation, according to Polish law, the vast majority of monuments, not mentioned in the registry, cannot be protected. It is necessary to quickly create comprehensive regulatory framework and take action in the field of identification and inventory of wooden architecture as well as creating effective preservation programs. There is a chance to preserve the significant part of heritage by further diversification of forms of protection and adaptation in cooperation and substantive assistance of conservation department and museums as well as financial support of the governments. I present specific proposals of solutions to this problem.
History, status quo and planned development of the hotel centre „Pastewnik” in Przeworsk
Authors: Urbańska Marta
Published: April 2020

The article regards the first initiative of its kind in Poland – i.e. the “Pastewnik” complex in Przeworsk in the Podkarpackie Voivodeship - its history, original plans, status quo, ideas of revitalisation. The complex was founded and partly completed by its spiritus movens, the then county architect Stanisław Żuk, in 1976. The enterprise, called “Przeworski Zamysł” (Przeworsk Concept) contains vernacular wooden structures from Przeworsk, itself a historic town which was located by the King Władysław Jagiełło, and from its vicinity (Gacie, Krzeczowice). The complex is situated at the former farm of the entail of Princes Lubomirski, near the princely residence itself. The transferred vernacular structures are an integral part of the camping facility. Archival descriptions by the architect testify to gigantic difficulties during the completion of the “skansen”, both in the times of the Polish People’s Republic and shortly after 1989. Nevertheless, the extant vernacular wooden structures underwent conservation and conversion (becoming hotel rooms and a renowned inn). Due to the deterioration of relics of wooden architecture in Przeworsk, the town authorities (represented by the then Vice-Mayor, Leszek Kisiel), started the cooperation with the Institute of History of Architecture and Preservation of Monuments, Cracow University of Technology. Its aims were surveys and measurements of the historic structures and studies of development of “Pastewnik”, elaborated by several teams of students within the framework of their summer internships, led by the authoress of this article. Concepts of revitalisation, additions and studies of site plan shall hopefully be implemented. The question of the future of the unusual complex is open – due, on one hand, to its exploitation and substandard of the camping, and on the other on the fact that the newly elected Mayor, dr Kisiel, has ambitious plans.

Renovation of the wooden St. John The Baptist Church in Zaborol village near Rivne in the context of neo-vernacular trends
Authors: Rychkov Petro , Smolińska Olga
Published: April 2020

In Volhynian architectural heritage the prominent place belongs to wooden churches which are outstanding examples of old vernacular building culture. At the same time a modern renovation of such churches tends to replacing of original exterior wooden planking with PVC siding. This problematic phenomenon can be characterized as neo-venacular trend. It actualizes the problem of preserving the authenticity of such architectural monuments. The example of the St. John the Baptist Church in the Zaborol village near Rivne demonstrates the negative consequences of such renovating work. The need to prevent and control this process is accentuated.

Published: April 2020

This article aims to stir the problem of obstacles and inconveniences faced by people with disabilities (including with reduced mobility , elderly , deaf , visually impaired and blind). The aim is to draw attention to the role played by the designer , both the architect and creator of utilitarian objects in shaping the impact on the comfort of living together in society of people with a complete physical and disabled. The need for education and promote greater awareness of these " dysfunctions " should be developed through places where non-disabled person is able to face the everyday barriers disabled person. An important aspect is to create awareness architect in the field of universal design at the stage of studies. More attention should focus on the design of everyday objects for the disabled so as not to have to change them later by artificial means. The article focuses on the problems and the positive examples of solutions in the process of shaping the architecture tailored to the needs of such people. The aim is also analysis of urban solutions that favor their functioning in everyday life. The authors are also examples of architectural and urban planning from both the Polish and the world. They show the importance and contribution of the architect in creating private and public spaces that surround us every day.
Repetitive construction processes scheduling using mixed-integer linear programming
Authors: Jaśkowski Piotr
Published: April 2020

Many construction projects contain several identical or similar units, such as floors in multistory buildings, houses in housing developments, sections of pipelines or highways. Repetitive processes arise from the subdivision of a generalized construction process into specific activities associated with particular units. In many cases it is possible to perform individual processes (repeated in each units) in alternative ways (modes). Regardless of the construction project procurement system, duration and cost are the key factors determining project’s economic efficiency and fulfillment of the owner’s needs and requirements. Minimizing project duration and cost are the most important criteria for schedule optimization. Processes that repeat from unit to unit are realized by specialized crews. Uninterrupted resource utilization becomes an extremely important issue for scheduling repetitive processes to minimize employment costs. In this paper, the problem of selecting appropriate modes and minimizing the total project cost and with a constraint on project duration is presented with respect to the continuity of the crews’ work. The paper uses the mixed integer linear programming to model this problem and uses a case study to illustrate it.
Mortar historical research methods – problems of restoration
Authors: Klimek Beata
Published: April 2020

Depending on various factors like time, increasing air pollution due to technological improvements of the present era together with insufficiency of inspection leads to the formation of damages on these buildings which are part of our historical heritage. Conservation of such buildings which are as important as historical documents should be the first and foremost target of any project. Plaster used in former time are a valuable source of information of building techniques used in the past. They are of interest to technologists and archaeologists, who use plasters as an additional criterion for establishing the chronology of the construction of walling in historic buildings. In accordance with the purpose of the investigations, appropriate analytical methods of a defined precision and specially chosen program are applied.

The first dimension of the current problem is the insufficiency of resources while the second dimension stems from the lack of proper evaluation of the material to be used in conservation and restoration. This study defines the importance of mortars and plasters along with their history and the reasons of deterioration. In addition, it sets up the information flow of mortar and plaster within a systematic decision making process. The necessary experimental methods for the production of new repair mortar or plaster that can be used in determining the character analysis of original mortar and deterioration morphology are also analyzed.

The necessity has been emphasized for the introduction of investigation standards to be universally binding, which would make it possible to compare the results of investigations carried out in different laboratories. The practice has been for analytical programs adopted and parameters measured to be individually chosen by the particular investigators and cannot be compare.
On the questions of an expression towards symbolical architecture
Authors: Serafin Aleksander
Published: April 2020

The article draws attention to two seemingly different approaches to the creation of an architectural form: the symbolic and the expressive, both in the context of their confrontation, and symbiosis. Symbol clearly supports the generation of the visual communication, while the escalation of the expression prevents a creativity from escaping in the literality and also it enriches the work of an individual element. Both those trends complementary creates the mechanism of modern architecture development, which obviously requires a consideration in the background of the extensive cultural context.
Effect of the cement paste volume on the consistency of mixes for high performance massive and self-compacting concretes
Authors: Zarzycki Bartłomiej , Piasta Wojciech
Published: April 2020

The article presents the results of research concerning the influence of the volume of cement paste and the w/c ratio on the consistency of concrete mixes for high-performance massive and self-compacting concrete. The research covered six types of concrete mixes containing from 220 to 420 dm3 of cement paste in a cubic meter. Three of them were designed as high-performance concrete and for comparison three conventional ones. The consistency was tested with two methods: concrete slump test and flow table test, also additional tests of self-compacting mix were made. Compressive strength test were conducted to prove that concretes are high-performance. A high influence of the volume of cement paste on the workability and consistency of fresh concrete mix has been found, while the influence of the w/c ratio is considerably lower due to the dosage of high-quality superplasticizer.
The spirit of modern sacral architecture
Authors: Zuba Karolina
Published: April 2020

Sacral architecture, due to its special function, is able to tremendously influence the society. Being a phenomenon for ages, it has undergone many changes alike the church liturgy, which to some extent impacts the church architecture. In the modern sacral architecture it is possible to distinguish two main tendencies in creating objects of temples. The first one is entirely modest – simplicity of form and interior. The second tendency, which may be described as the opposite of the former, presents monumentalism usually connected with rich symbolism. Modern temples also show references to historical forms. Another factor which may influence the form and function of the sacral object is the religious beliefs of its author.
Asociación entre resistencia a antibióticos y serotipos en Salmonella de transmisión alimentaria
Authors: Juez García María , Álvarez Sánchez Julio , Sotodosos Carpintero Mercedes , Ugarte-Ruiz María
Published: April 2020

La salmonelosis es una de las principales zoonosis de transmisión alimentaria a nivel mundial y europeo y está causada por Salmonella enterica subsp. enterica, que se divide en más de 2.500 serotipos. Una de las principales fuentes de infección en humanos son el huevo y sus derivados. La salmonelosis suele cursar con signos gastrointestinales autolimitantes, pero en casos de bacteriemia, pacientes graves o inmunodeprimidos es imprescindible el tratamiento antibiótico. Por ello, la aparición de resistencias a antimicrobianos en cepas de Salmonella supone una amenaza para la Salud Pública.
En este estudio se ha evaluado la diversidad de serotipos y el nivel de resistencia a nueve antimicrobianos en una colección de aislados de Salmonella obtenidos a partir del programa de vigilancia llevado a cabo durante once años (2007-2017) en huevos de supermercado situados en la Comunidad de Madrid.
En el periodo analizado se obtuvieron 243 aislados de 23 serotipos diferentes, de los cuales Enteritidis, Infantis, Rissen, Anatum y Typhimurium constituyeron el 80% del cepario. Enteritidis fue el serotipo más frecuente (41%). Los niveles de resistencia se situaron por debajo del 10% excepto en el caso de la ciprofloxacina, el ácido nalidíxico, la tetraciclina y la ampicilina, variando en función del serotipo. El 41% de las cepas fueron susceptibles a todos los antimicrobianos pero casi un 8% de las mismas se clasificaron como multirresistentes (resistentes a 3 familias de antimicrobianos). Aunque los niveles de resistencia fueron en general bajos, existieron algunas excepciones (como la resistencia a quinolonas o la observada en cepas de S. Rissen). Los resultados demuestran la importancia de los programas de vigilancia y la utilidad de contrastar los datos obtenidos en alimentos con los encontrados en animales y casos clínicos en personas para evaluar la evolución temporal de serotipos y resistencias en Salmonella.

O breve estudo que segue é uma tentativa de compreensão da experiência da solidão tal como ela dá seus primeiros sinais na 3ª Consideração Extemporânea, de Friedrich Nietzsche, tentando delineá-la, não como simples conceito, se não em íntima vinculação em outra figura conceitual nietzscheana, o espírito livre, no que concerne ao seu tornar-se si mesmo. Como uma categoria crítica, o espírito livre (ainda que não apareça formalmente neste escrito de Nietzsche como o será em Humano, demasiado Humano) é confrontado o tempo inteiro às poderosas injunções da cultura, as quais insistem em tragá-lo para dentro de um modo de vida gregário uniformizante, nivelador e paralisante, retirando toda possibilidade de qualquer solidão e, por consequência, a liberdade de criar a si mesmo que a ideia do tornar-se, do devir, implica.
Filosofia em "Tempos Sombrios": A leitura de Critão sobre Sócrates na pólis diante das leis e da opinião da maioria_Um olhar arendtiano
Authors: Hornich Daner
Published: April 2020

As questões postas para Sócrates consistem em “guiar-se” pelo conselho dos outros para salvar a sua vida; para não se privar dos amigos e muito menos legar infelicidade para os que dispõem de dinheiro para ajudá-los entre si quando necessário: pois, qual é o valor do dinheiro quando a amizade é colocada em jogo? Sócrates não se guia pelas cabeças alheias, pois examina as próprias questões (colocadas por ele ou outros) como um provocador, ou parteiro das reflexões e pensamentos. Isso porque as respostas indicadas por Sócrates parecem um desvio de rota, ao começar um diálogo sobre a opinião da maioria, que, para Critão, é ponto significativo, e para Sócrates não, pois não devemos nos preocupar com a opinião da maioria, mas com as considerações dos melhores.

Nascido em 1920, Celso Furtado está, certamente, entre os principais pensadores sociais brasileiros e sua relevância extrapola as fronteiras nacionais. Ao longo de mais de 50 anos escreveu sobre temas variados; abordou as dimensões políticas, econômicas, culturais, burocráticas etc., da sociedade e do Estado brasileiro; participou de eventos políticos importantes da história do país e teve destacadas participações em organizações internacionais. Autor de obra vasta e profunda, Furtado deixou um legado relevante para o pensamento social e político brasileiro, assim como deixou pistas abertas para o prosseguimento de investigações sobre o Brasil. A riqueza de empreendimentos como esses, de junção de diversos artigos sobre um autor e sua obra está, justamente, na possibilidade de ampliar o leque de olhares e perspectivas sobre os temas, objetos e problemas tratados por um pensador de grande envergadura como Celso Furtado.

Published: April 2020

Introdução: A Aprendizagem Baseada em Problema (ABP) vem estimulando transformações nos currículos de escolas médicas desde a década de 1960. Nos dias atuais, novas tecnologias educacionais (TE) se multiplicam e potencializam diferentes modos de ensinar e aprender. Nos cursos de saúde, o avanço das TE produziu a ABP Híbrida, metodologia que usa recursos do e-learning, combinando atividades a distância e presenciais, para promover o ensino-aprendizagem de forma ativa. Objetivo: Relatar a experiência do uso de recursos de e-learning na ABP em um curso de medicina. Método: Descrever e analisar a experiência do uso do e-learning incorporado como estratégia facilitadora e integradora da ABP no curso de graduação em medicina recém-implantado no interior no Nordeste brasileiro.  Resultado: Estratégias de e-learning são empregadas em todos os passos da ABP, seja como ferramenta de registro, seja como mediação de discussões virtuais, facilitando a interação e construção coletiva do conhecimento, oportunizando, assim, experiências diversas de aprendizado para estudantes com diferentes estilos de aprendizagem. Conclusão: A flexibilidade de tempo e espaço, ao realizar atividades à distância, amplia as possibilidades do ensinar e aprender, tocando aspectos como interação entre os estudantes, profundidade de discussões e envolvimento no processo tutorial.

Introdução e objetivo: A hospitalização e o processo de adoecimento infantil influenciam diretamente o aspecto emocional e de enfrentamento da criança. Neste contexto, destacamos a abordagem à criança e ao acompanhante pelo profissional de enfermagem. Buscou-se relatar as contribuições dos recursos audiovisuais na assistência integral à criança. Método: Trata-se de estudo descritivo, qualitativo, do tipo relato de experiência. O cenário envolve a sala de procedimentos de uma unidade clínica pediátrica de um hospital escola, em Maceió-Alagoas, e as impressões observadas no dia a dia dos profissionais, no primeiro semestre de 2019. Resultados e discussão: Este ambiente terapêutico vem possibilitando o processo de acolhimento e estabelecimento de vínculos. Os recursos audiovisuais permitem a relação das tecnologias duras e leves dentro do ambiente hospitalar através de imagens infantis, musicoterapia, vídeos educativos, desenhos, o lúdico e o brincar de maneira inovadora. Com isso, percebe-se melhor aceitação dos cuidados, a assistência centrada na criança e acompanhante, com uma abordagem humanizada e interdisciplinar. Conclusão: A utilização de recursos audiovisuais na rotina da clínica tem se mostrado positiva, minimizando medos, traumas, tornando as intervenções necessárias mais colaborativas e aproximando o acompanhante, criança e equipe interdisciplinar.

Published: April 2020

Introdução: O fluxograma analisador pode ser utilizado pela equipe de saúde para compreender os processos de trabalhos. Ele permite uma visualização do funcionamento da unidade e consequentemente os entraves que existam no fluxo. O objetivo deste trabalho foi relatar a experiência de uma oficina com a equipe de uma Unidade Básica de Saúde (UBS) do município de Guaiuba para identificar o percurso de entrada até a saída dos pacientes atendidos, bem como a oferta de serviços realizados nesta unidade. Métodos: É um estudo observacional em formato de relato de experiência da construção de um fluxograma analisador a partir de uma oficina com a equipe de saúde da família de uma UBS. Resultados: Uma grande dificuldade da recepção na unidade é a fila de usuários que se forma na madrugada em busca de senha que dá acesso às consultas. O sistema utilizado pela unidade é por ordem de chegada, pois a UBS não possui um sistema de classificação de risco. Conclusão: A experiência vivenciada por todos os profissionais da UBS foi proveitosa, onde em roda de conversa, cada profissional elencou e problematizou suas dificuldades para que em equipe possam planejar as ações no serviço de saúde.
