High-speed terahertz color imaging using a 100 kHz line scan camera
Authors: Tsubouchi Masaaki , Nagashima Keisuke
Published: May 2020

We develop a high-speed two-dimensional (2D) terahertz (THz) color imaging system for practical applications. This system performs THz time-domain spectroscopy (THz-TDS) measurements in one-dimensional (1D) space simultaneously to reduce the spatial scan from 2D to 1D and obtains the 2D THz color image in which the spectral data is possessed in each pixel. We realize measurements on the image with 750 × 1000 pixels (13 mm × 25 mm) with the spatial resolution of 1.5 mm within 10 seconds. This is two orders of magnitude faster than conventional THz color imaging methods. High-speed 2D THz color imaging will be used in non-destructive and non-invasive inspections of industrial products and biological tissues in the future.

Published: May 2020

Silicon (Si), germanium (Ge), and gallium arsenide (GaAs) are familiar semiconductors that always act in the role of optical dielectrics. However, these semiconductors also have plasmonic behaviors in ultraviolet (UV) ranges due to the strong interband transitions or valence electrons. And few studies are aimed at investigating plasmonic properties in the semiconductor at the nanoscale. In this work, we discuss UV plasmonics and sensing properties in single and dimer Si, Ge, and GaAs triangular prism meta-antenna systems. The results show that obvious local surface plasmon resonances (LSPRs) can be realized in the proposed triangular prism meta-antennas, and the resonant wavelength, electromagnetic field distribution, surface charge distribution, and surface current density can be effectively tuned by structural and material parameters. In addition, we also find that the Si triangular prism meta-antenna shows more intense plasmonic responses in UV ranges than that in the Ge or GaAs triangular prism nanostructures. Especially, the phase difference between the triangular prism nanostructure and light source can effectively regulate the symbol and value of the surface charge. Moreover, the great enhancement of electric field can be seen in the dimer triangular prism meta-antennas when the distance of the gap is g<5 nm, especially g=1 nm. The most interesting result is that the maximum of refractive index sensitivity s and figure of merit (FoM) are greatly enlarged in dimer triangular prism meta-antennas. Particularly, the sensitivity can reach up to 215 nm/RIU in the dimer GaAs triangular prism meta-antennas, which is improved more than one order of magnitude. These research results may play important roles in applications of the photo detecting, plasmonic sensing and disinfecting in UV ranges.

In-system optimization of a hologram for high-stability parallel laser processing
Authors: Zhang Honghao , Hasegawa Satoshi , Takahashi Hidetomo , Toyoda Haruyoshi , Hayasaki Yoshio
Published: May 2020

A method for optimizing a computer-generated hologram (CGH) for high-stability laser processing is proposed. The CGH is optimized during laser processing; therefore, unpredicted dynamic changes in the laser processing system, in addition to its static imperfections, are automatically compensated for by exploiting the rewritable capability of the spatial light modulator. Consequently, the short-term and long-term stability are improved, which will contribute to the realization of high-speed, high-precision laser processing. A CGH that generated 36 parallel beams was continuously optimized, and the maximum uniformity reached 0.98, which is higher than reported in previous research. To the best of our knowledge, this is the first demonstration of gradual improvement of parallel laser processing with in-process optimization of the CGH. Furthermore, it was also demonstrated that the performance of the laser processing system against unexpected disturbances was improved.
Education System re-engineering with AI (artificial intelligence) for Quality Im-provements with proposed model
Authors: Muzammul Muhammad
Published: May 2020

Re-engineering (RE) of existing educational institutions (EI) with adoption of latest technology trends (LTT) in form of artificial intelligence (AI) can be great effective in term of quality systems. Increase in student’s strength in class and terrorist attacks on EI urged us to introduce such approach that can assure education quality. Class monitoring with heavy strength always remain major issue for teacher during lecture delivery. In this paper, we implemented reengineering using artificial intelligence based two theories of 1) Multi-face recognition (MFR) system 2) Facial expression recognition (FER) system. Both of these theories supported by intelligent techniques as principal component analysis (PCA), discrete wavelet transform (DWT) and k-nearest neighbor (KNN). After implementation of these intelligent techniques student’s attentiveness will increase. Our developed system can detect expressions like happiness, repulsion, fear, anger, and confusion. Student’s attentiveness score will be displayed on screen. Teacher can interpret on the basis of attentiveness %age. System decision making can be helpful for class continuity or short break. This system is also an application of an expert system (ES) and knowledge base system (KBS) for educational quality assurance. A similar monitoring system was imposed in china with Hikvision Digital Technology. Predations results proved monitoring can be best way for education quality.
An Information Recognition System for Complex Images
Authors: Abdullayeva Gulchin , Alizade Ulker
Published: May 2020

An approach to objective assessment of ultrasound examination is presented. To this end, modern information technologies and a set of mathematical methods in the form of a package are proposed. In this paper, diagnosis is viewed as a three-step process, and closed sub-objects are investigated using complex images, which pertains to the earliest diagnostic stage. For this purpose, three new features related to the disclosure of a growth are included in the paper. A system that performs the detection of the growth and finds the coordinates, area, gravity center and color palette of the obtained image is developed. By means of the created software package, the image is cleared from noise, filtering operations are performed, boundaries are defined more clearly and recognition by the mathematical morphology method is completed using selected classifiers. The main purpose is to direct doctor's attention to the presence of the pre-indicator of a non-specific symptom and to control the future development of the growth. The accuracy of the system is confirmed by the detection and identification of closed growths in the images taken in an ultrasound examination of internal organs of the human body. The system's operability has been tested directly on the ultrasound images (138 cases investigated), with the result of 98.8% at the diagnostic stage, 92, 03% at the early diagnostic stage; 2 cases have been recorded at the earliest diagnostic stage in 2018 and the frequency of monitoring has been determined.
Los juegos tradicionales y la educación en Canarias: de las propuestas del siglo XIX a las regulaciones autonómicas
Authors: Almeida Aguiar Antonio S. , Castro Núñez Ulises S.
Published: May 2020

Una de las claves metodológicas de la educación contemporánea, después de los cambios que se produjeron a partir de la renovación pedagógica del siglo XIX, es la incorporación del juego como base de la enseñanza, especialmente en las primeras edades del desarrollo del ser humano. Una de las modalidades lúdicas que nos ha interesado para el presente estudio son los denominados juegos tradicionales. Partiendo de un análisis conceptual que trata de delimitar las características de los juegos tradicionales, hemos realizado una aproximación a los mismos desde las primeras propuestas generales planteadas por intelectuales, muchos de ellos vinculados al movimiento regeneracionista en las islas, hasta las regulaciones autonómicas que incluyen estos juegos dentro del currículum educativo. Para conseguir estos objetivos, hemos utilizados fuentes primarias, tanto de la prensa general como de la prensa pedagógica, especialmente del siglo xix, así como textos legales, decretos y disposiciones que articulan los juegos tradicionales en la enseñanza en Canarias del siglo XXI.
Retrospectiva histórica del juego y deporte tradicional a través de la cultura segoviana
Authors: Jiménez Vaquerizo Enrique
Published: May 2020

El presente artículo nace con la intención de mostrar una visión retrospectiva de los juegos y deportes tradicionales, arraigados en la tradición oral, de una provincia como Segovia, con mucho peso histórico en el ámbito de estas manifestaciones dentro de la península ibérica.La primera línea de investigación nos indica cómo el ejercicio, la cultura y el folclore afines a dichas prácticas tienen un nexo común. Este no es otro que formar parte de una amplia red de cañadas reales, como la Cañada Segoviana y la Occidental Cañada Leonesa, comunicadas ambas en la Cañada de «Vera de la Sierra».La segunda línea de investigación tiene como eje la economía de la Mesta, la trashumancia y la comercialización del paño, generándose a través de estos procesos una fuerte transmisión cultural a nivel peninsular.Una última línea de investigación se centra en torno a la riqueza histórica de Segovia y a las continuas repoblaciones emanadas de la reconquista y de los asentamientos de población correspondientes.La parte final del trabajo ofrece una clasificación y una reflexión sobre los recursos pedagógicos que nos pueden facilitar la labor docente desde la escuela y su deporte federado como la verdadera exposición de lo que fue y debería ser su práctica.

A partir de aquí, y como resultado, se proponen 30 variantes del juego.La finalidad es ofrecer un ejemplo de las múltiples opciones, en este caso de las cuatro esquinas, para mantener viva la llama de la tradición, aunque adaptándola a la actualidad.
Luis Domingo de Rute, arquitecto de modelos para la construcción de escuelas públicas en España a comienzos del siglo XX
Authors: Rodríguez Méndez Francisco Javier
Published: May 2020

La Colección de planos modelos de escuelas públicas de enseñanza primaria, publicada en noviembre de 1908, constaba de doce modelos de escuelas de complejidad creciente. Habían sido diseñados por Luis Domingo de Rute, arquitecto adscrito al Negociado de Arquitectura escolar del incipiente Ministerio de Instrucción pública y Bellas Artes. Tenían por objeto servir de pauta o norma a la que los arquitectos habían de sujetarse en el futuro para el proyecto de edificios escolares públicos de enseñanza primaria. Aunque la Colección de Rute gozó de gran difusión, lo cierto es que su aplicación fue bastante limitada a causa de la rápida obsolescencia de los modelos y, también, del prematuro fallecimiento de su autor. Circunstancias ambas que sin duda contribuyeron a acelerar la creación, una década más tarde, de la Oficina Técnica para la Construcción de Escuelas por el Estado.No hay estudio referido a la arquitectura escolar española de comienzos del siglo XX que no mencione dicha colección y el nombre de su autor. Aparte de ello, poco más ha trascendido sobre la trayectoria de Luis Domingo de Rute. El objetivo de la presente investigación es doble: por un lado, rescatar la figura de Rute del olvido en el que se ha visto sumida –prácticamente, desde la publicación de su Colección– y, por otro, profundizar en el análisis de los modelos de escuela a él debidos.

Published: May 2020

La universalización de la enseñanza que se produce a lo largo del siglo xx en España llegó con fuerza a las provincias periféricas sobre todo a partir de los años sesenta, si bien el proceso de multiplicación de escuelas se había acelerado desde los años veinte. Con la llegada de la democracia podemos decir que en las capitales casi todos los niños estaban escolarizados y contaban con buenos locales de enseñanza.Se recoge aquí el proceso histórico de cambio que comentamos, analizando Badajoz capital a través de la prensa y los archivos, estudiando las aulas y los edificios escolares. Se pasó de la habitación reaprovechada en casas viejas o destartaladas al moderno palacio tecnificado y con todas las dotaciones. Esta evolución tuvo un impacto en el urbanismo, pues se construyeron nuevas escuelas en todas las barriadas.

Published: May 2020

Introduction: Multi-stages refinement of a bulky flap after composite defects reconstruction of multiple facial units has been a challenging situation. Goals including restoration of periorbital and malar area and redefining the aesthetic aspects of the units as well as the surrounding nasolabial area with multiple refinements and microfat graft. Methods: A 50-year-old male patient with a history of solitary fibrous tumor underwent wide excision of left periorbital, infraorbital, lateral nasal sidewall, and malar area. The defect is enclosed with Anterolateral Thigh Free Flap (ALT). Bulkiness of the flap, sunken left nasolabial, and asymmetric alar nasal unit were found during outpatient follow-up. These problems lead to the necessity of refinement procedure to reduce the bulkiness to improve the aesthetic outcome of the patient. Microfat graft was the method chosen to volumized the sunken nasolabial and asymmetric alar nasal unit. Results: Patient is satisfied with the result due to improvement of alar nasal units symmetricity and reduced bulkiness of the flap area. No complication was observed. Conclusion: Meticulous planning and staging of the surgical refinement procedures in conjunction with microfat graft results in good aesthetic outcome and satisfies the patient and reduces the possibility of complications.

Published: May 2020

INTRODUCTION:

The low FODMAP diet (LFD) reduces symptoms and bifidobacteria in irritable bowel syndrome (IBS). β-galactooligosaccharides (B-GOS) may reduce the symptoms and increase bifidobacteria in IBS. We investigated whether B-GOS supplementation alongside the LFD improves IBS symptoms while preventing the decline in bifidobacteria.

METHODS:

We performed a randomized, placebo-controlled, 3-arm trial of 69 Rome III adult patients with IBS from secondary care in the United Kingdom. Patients were randomized to a sham diet with placebo supplement (control) or LFD supplemented with either placebo (LFD) or 1.4 g/d B-GOS (LFD/B-GOS) for 4 weeks. Gastrointestinal symptoms, fecal microbiota (fluorescent in situ hybridization and 16S rRNA sequencing), fecal short-chain fatty acids (gas-liquid chromatography) and pH (probe), and urine metabolites (1H NMR) were analyzed.

RESULTS:

At 4 weeks, adequate symptom relief was higher in the LFD/B-GOS group (16/24, 67%) than in the control group (7/23, 30%) (odds ratio 4.6, 95% confidence interval: 1.3–15.6; P = 0.015); Bifidobacterium concentrations (log10 cells/g dry weight) were not different between LFD and LFD/B-GOS but were lower in the LFD/B-GOS (9.49 [0.73]) than in the control (9.77 [0.41], P = 0.018). A proportion of Actinobacteria was lower in LFD (1.9%, P = 0.003) and LFD/B-GOS (1.8%, P < 0.001) groups than in the control group (4.2%). Fecal butyrate was lower in the LFD (387.3, P = 0.028) and LFD/B-GOS (346.0, P = 0.007) groups than in the control group (609.2).

DISCUSSION:

The LFD combined with B-GOS prebiotic produced a greater symptom response than the sham diet plus placebo, but addition of 1.4 g/d B-GOS did not prevent the reduction of bifidobacteria. The LFD reduces fecal Actinobacteria and butyrate thus strict long-term use should not be advised.
Liberia’s Belle Yella Prison Camp (1910–1990): Repression, Stigma, and Forced Labor in the Heart of the Rainforest
Authors: Nevin Timothy D. L.
Published: May 2020

This article represents research over a five-year period into the history of Belle Yella prison, an infamous prison associated with the incarceration of political prisoners and hardened criminals located deep in the rainforest of what is now Gbarpolu County, central Liberia. The article uses both extensive oral histories and archival documents to shed light on the eighty-year-long history of the site. The author argues that Belle Yella prison was utilized by past Liberian presidents as a place of banishment for political prisoners that were viewed as a threat to their regimes, especially during periods of political turmoil. These prisoners were forced to labor on private farms and survive under inhumane conditions that both violated their civil liberties and their human rights. In the conclusion, the author urges that the site of the prison be turned into a memorial so that visitors can pay homage to those who died there and learn lessons from the past.
A Contribution from the African Cultural Philosophy towards a Harmonious Coexistence in Pluralistic Societies
Authors: Rodríguez López Fermín
Published: May 2020

This paper presents a comprehensive review of the African cultural philosophy. The aim of the study is to focus on identifying the elements present in the African ontology and epistemology which may contribute towards the consecution of a harmonious coexistence in the increasing plurality of today society. Based on an understanding of reality in which everything dwells in complementarity, interdependence and mutuality, the African worldview approaches difference and particularity as opportunities for mutual growth and cooperation. The acknowledgement of such an intimate mutual relatedness among all human groups which form a given society is the African key to understand the process towards coexistence. This sheds light on the understanding of social dialogue, the peacebuilding processes, and the means for the resolution of conflicts.
K-nearest neighbor performance for Nusantara scripts image transliteration
Authors: Widiarti Anastasia Rita
Published: May 2020

The concept of classification using the k-nearest neighbor (KNN) method is simple, easy to understand, and easy to be implemented in the system. The main challenge in classification with KNN is determining the proximity measure of an object and how to make a compact reference class. This paper studied the implementation of the KNN for the automatic transliteration of Javanese, Sundanese, and Bataknese script images into Roman script. The study used the KNN algorithm with the number k set to 1, 3, 5, 7, and 9. Tests used the image dataset of 2520 data. With the 3-fold and 10-fold cross-validation, the results exposed the accuracy differences if the area of the extracted image, the number of neighbors in the classification, and the number of data training were different.
Walory poznawcze kategorii tożsamości społecznej jednostki
Authors: Machaj Irena
Published: May 2020

In the article, the author raises the question of what we can get to know or rather what social phenomena we can reach thanks to the studies on the individual’s social identity. The author adopts three essential features of sociological meaning of social identity: concentration on the consciousness part of life, subjective research orientation and the relational character of the individual’s social identity. Cognitive values are presented in the form of explicitly articulated questions, which are posed when we research on the identity of the individual in itself and when it helps to discover the other social phenomena, such as systems of values, mechanisms of the social exclusion-inclusion and mechanisms of the social diversity.

Pnioki, krzoki i ptoki… projekty tożsamościowe liderów organizacji śląskich
Authors: Ewa Michna Ewa Michna
Published: May 2020

Ethnic leaders play an increasingly important role in shaping the ethnic ties and functioning of ethnic groups. National and ethnic elites are also advocates of collective identity. They create the criteria of ethnic identity and develop identity constructs. Such constructs are to be the frame for the creation of the individual identity of the members of the group. While formulating identity projects leaders must be in dialogue with the group which they wish to influence. In this paper, I will show the complexity of these processes. In the eighty narratives collected during my research on Silesian ethnic leaders we see individual ways of constructing identity and boundaries of group practices of everyday life (where identity is negotiated and multiple, based on the symbolic resources and categorizations available in the group – the pnioki, krzoki and ptokiof the title), and, on the other hand, identity projects constructed in a more conscious way. The latter are created in the context of identity politics, which my interlocutors lead on behalf of the collective entity (in this case, the Silesian community).
Subwavelength structured silicon waveguides and photonic devices
Authors: Sun Lu , Zhang Yong , He Yu , Wang Hongwei , Su Yikai
Published: May 2020

Subwavelength structures such as subwavelength gratings (SWGs) and subwavelength metamaterials are capable of tailoring the optical properties of materials and controlling the flow of light at the nanoscale. The effective indices of the subwavelength structured strip and slab waveguides can be changed in a wide range by choosing an appropriate duty cycle or a filling factor of silicon, which provides an effective method to manipulate the optical field and achieve effective index matching for functional devices. Recent advances in nanofabrication techniques have made it possible to implement subwavelength structures in silicon strip and slab waveguides. Here we review various approaches used to design subwavelength structures and achieve exotic optical responses and discuss how these structures can be used to realize high-performance silicon photonic devices. Both one-dimensional SWG devices and two-dimensional subwavelength metamaterial devices are covered in this review, including subwavelength structure–based polarization handling devices, mode manipulation devices, and building blocks for integrated optical interconnects. Perspectives on subwavelength structured silicon photonic devices are also discussed.

Origin Specific Genomic Selection: A Simple Process To Optimize the Favorable Contribution of Parents to Progeny
Authors: Yang Chin Jian , Sharma Rajiv , Gorjanc Gregor , Hearne Sarah , Powell Wayne , Mackay Ian
Published: May 2020

Modern crop breeding is in constant demand for new genetic diversity as part of the arms race with genetic gain. The elite gene pool has limited genetic variation and breeders are trying to introduce novelty from unadapted germplasm, landraces and wild relatives. For polygenic traits, currently available approaches to introgression are not ideal, as there is a demonstrable bias against exotic alleles during selection. Here, we propose a partitioned form of genomic selection, called Origin Specific Genomic Selection (OSGS), where we identify and target selection on favorable exotic alleles. Briefly, within a population derived from a bi-parental cross, we isolate alleles originating from the elite and exotic parents, which then allows us to separate out the predicted marker effects based on the allele origins. We validated the usefulness of OSGS using two nested association mapping (NAM) datasets: barley NAM (elite-exotic) and maize NAM (elite-elite), as well as by computer simulation. Our results suggest that OSGS works well in its goal to increase the contribution of favorable exotic alleles in bi-parental crosses, and it is possible to extend the approach to broader multi-parental populations.

Indigenous Communities and Community-Engaged Research: Opportunities and Challenges
Authors: McGregor Catherine , McIvor Onowa , Rosborough Patricia
Published: May 2020

As the inaugural issue of The Engaged Scholar Journal made apparent, while there is significant evidence that community-engaged scholarship has reached a critical mass in Canadian institutions, many important junctures still need to be explored. One such issue is the recognition of Indigenous community-engaged scholarship. Working from an appreciative stance, the three authors of this article explore how existing community-engaged scholarship theory intersects with their own experiences as academics—teasing out some of the potentialities and tensions that exist in the lived spaces where community-engagement thrives, amidst the boundaries of institutional tenure and promotion policies. The article also explores what kinds of practices or policies might be usefully considered by institutions, particularly around how to engage in more inclusive processes of scholarly recognition. We argue it is possible to embrace tools that create reciprocal, respectful and meaningful relationships between Indigenous and non-Indigenous peoples who share deeply held beliefs in the power of research to alter lives and communities in powerful ways.

Published: May 2020

Assess, Redress, Re-assess: Addressing Disparities in Respiratory Health Among First Nations is an ongoing community-based participatory research initiative involving two First Nations communities in Saskatchewan. The initiative’s rationale is grounded in the ethos of transformative community-based participatory research and facilitated through integrated knowledge translation with the aim of building community capacity. The initiative’s goal was to engage community members to actively participate in all research phases, from the development of the research questions to dissemination of results and evaluation of community-chosen interventions that evolved from the results. After baseline assessment of predictors and indicators of respiratory health, a program of integrated knowledge translation was adopted. As part of this program, a community-researcher collaboration was put in place that produced two knowledge translation symposia. The two symposia have brought together First Nations community members, interdisciplinary researchers, federal and provincial policy makers, and multiple Aboriginal organizational stakeholders. The symposia provided a pathway for knowledge synthesis and sharing to ultimately integrate knowledge into practice and enable First Nations’ community capacity building in addressing and redressing critical respiratory health issues. This article delineates the processes involved in developing this model of integrated knowledge translation and highlights the continuing engagement with the participating communities supported by Knowledge Translation (KT) Symposia.

Authors: LaVallee Amanda , Troupe Cheryl , Turner Tara
Published: May 2020

Adding a Métis voice to the larger discourse on Indigenous (Métis, First Nation, and Inuit) health research, this work shares experiences and insights gained in relationship building from a community-based Métis research project entitled, Converging Methods and Tools: A Métis Group Model Building Project on Tuberculosis. A collaborative partnership between PhD student Amanda LaVallee, the Métis Nation – Saskatchewan (MN-S) Health Department and two independent health researchers, the project, conducted from 2010 to 2012, incorporated a System Dynamics participatory methodology called Group Model Building (GMB), with Métis research methods, ethics, and knowledge, to build a model of tuberculosis (TB) experience in Saskatchewan Métis communities. This article examines the co-author’s experiences with these collaborative methodologies and with the other partners in the research project, as well as the relational research stories that were essential to the practice of Metis community-based research. Moving beyond discussion of objectivity toward transparency about our presence within the research relationship, this work offers our collaborative experience as a success, and provides inspiration and insight on how to engage in ethical, competent, culturally appropriate, and relevant community-based research.

ESTRATEGIAS DE FINANCIAMIENTO, UN RETO PARA LAS PYMES COMERCIALES DE GUANACASTE
Authors: Canossa-Montes de Oca Héctor , Rodríguez-Alcocer Roberto
Published: May 2020

Las empresas requieren una óptima administración financiera para permanecer y crecer en el mercado, según estudios de Costa Rica ocho de cada diez empresas no sobreviven más de diez años, aunado a que Guanacaste contabiliza únicamente el cinco por ciento de total de pymes del país, por lo que se requieren nuevos emprendimientos y la consolidación de las actuales para hacer crecer este segmento empresarial y por ende contribuir con el desarrollo económico de la provincia. Este artículo tiene como objetivo analizar retos para el financiamiento en las empresas estudiando la perspectiva de las pymes comerciales de Guanacaste. Los resultados obtenidos incluyen que el sector analizado ha desarrollado sus negocios a través de un financiamiento personal con ahorros, o incluso usando recursos provenientes de otro empleo y proveedores, y en su mayoría los recursos sumados de inversión inicial  no superan los cinco millones de colones; pero el deseo de expansión requiere que estas empresas realicen un análisis y evaluación del endeudamiento, como fuente de inversión para posicionarse en el mercado, y para la mayoría los temas financieros son desconocidos. Estas empresas deben reconocer la relevancia de la gestión financiera y buscar estrategias para crecer mediante un constante aprendizaje con capacitaciones sobre financiamiento y administración en general. Esta investigación promueve una orientación hacía la gestión financiera de una manera responsable, buscando la rentabilidad y el crecimiento de las pymes comerciales de Guanacaste y Costa Rica.

A través de entrevistas de profundidad, el presente artículo indaga acerca del legado de Antonio Maceo y la colonia cubana en Mansión de Nicoya, Guanacaste, por medio de la percepción de los recuerdos del paisaje de mediados del siglo XX en la memoria de cinco entrevistados.  El artículo utiliza el concepto de paisaje como una forma de ver y de percibir el entorno, así como jeroglífico social, a través del cual es posible denotar y analizar relaciones sociales y económicas en un determinado lugar.  En el análisis de las entrevistas, se determinan tres derivaciones por medio del análisis de la idea del paisaje en los entrevistados: la presencia del legado de la figura de Maceo y de la colonia cubana como fuente de identidad comunal, Mansión como uno de los centros logísticos más importantes de la Guanacaste de la mitad del siglo XX, y Mansión como centro de rica producción agrícola para el mercado regional y nacional.
Designing of alternative polymeric nano-chelator for treatment in acute iron poisoning by molecular imprinting approach
Authors: KARAKOÇ Veyis
Published: May 2020

The aim of this study is to develop an alternative polymeric chelating agent for rapid and selectively removal with high capacity of Fe3+ ions from the gastrointestinal tract for the oral treatment of acute iron poisoning. For this purpose, Fe3+ imprinted poly(hydroxyethyl methacrylate-N-methacryloyl-(l)- glutamic acid) (HEMA-MAGA) nanoparticles synthesized by surfactant free emülsiyon polymerization. Molecular imprinting (MIP) technique is used to enhance the selectivity of nanoparticles. Due to being carboxyl and amide groups on the MAGA monomer, it was chosen as a chelating agent for Fe3+ ions. Before the synthesizing of Fe3+ imprinted polymer, Fe3+ ions were complexed with MAGA and then Fe3+ imprinted nanoparticles were synthesized in the presence of this Fe3+-MAGA complexes. Poly(HEMA-MAGA) nanoparticles were characterized by infrared spectroscopy (FTIR), atomic force microscopy (AFM). Average particle size and size distribution also determined by Zeta sizer. The specific surface area and mead diameter of the Fe3+ imprinted poly(HEMA-MAGA) nanoparticles was 895 m2.g-1 and 95.3 nm, respectively. The maximum Fe3+ ions binding capacity of the poly(HEMA-MAGA) nanoparticles at pH:4.0 were 206.4 mg.g-1 nanoparticles. Fe3+ removal performance of the Fe3+ imprinted poly(HEMA-MAGA) nanoparticles with presence of other ions, optimum medium pH, temperature and equilibrium binding time were also investigated. Fe3+ removal studies were performed in both aqueous solution and intestinal mimicking solution.The results indicate that Fe3+ imprinted poly(HEMA-MAGA) nanoparticles is an alternative chelating agent for the selective Fe3+ ions removal with a short time and very high capacity.
Twelve Tips for COVID-19 friendly learning design in medical education
Authors: Reyna Jorge
Published: May 2020

This article was migrated. The article was marked as recommended. The COVID-19 pandemic has caused educational institutions around the world to close their doors and move their teaching and learning into the online space. For many medical educators, who usually rely on face-to-face and blended instruction, this presents a challenge. By rethinking learning design, medical educators can ensure a smooth transition of their subjects into the online space. However, because of the immersive nature of medical education, not all teaching and learning activities can be delivered online. This paper outlines twelve tips using evidence-based educational practices and a student-centred approach. The twelve tips presented and discussed in this paper can help medical educators to transition to online learning and maintain the integrity of their subjects. They can also promote student self-regulation, help develop graduate attributes, and generally enhance learning experiences during pandemic social distancing. Finally, these tips can be used to rethink medical education in the post-pandemic era.

RESUMO (Criptógamos do Parque Estadual das Fontes do Ipiranga, São Paulo, SP, Brasil. Algae, 45: Bacillariophyceae (Naviculales: Brachysira)). O levantamento florístico do gênero Brachysira Kützing (Naviculales) do Parque Estadual das Fontes do Ipiranga (PEFI), São Paulo, SP, Brasil, resultou da análise de 31 preparações permanentes de material coletado entre 1991 e 2017. As amostras de água e de substratos (macrófitas e rochas) de sistemas lênticos, riachos e do hidrofitotério foram coletadas e posteriormente oxidadas para análise ao microscópio de luz. Nove espécies e um morfotipo foram encontrados em 15 amostras de material do PEFI, sendo quatro novas citações para o Brasil (Brachysira cf. calcicola Lange-Bertalot, Brachysira frenguellii (Manguin) Lange-Bertalot & Moser, Brachysira huitotarum Vouilloud, Sala & Núñez-Avellaneda e Brachysira intermedia (Østrup) Lange-Bertalot). Brachysira subrostrata Lange-Bertalot foi registrada pela primeira vez no Estado de São Paulo.
Viaduct maintenance for future traffic demands and earthquakes

Published: May 2020

The Tokyo Metropolitan Expressway in Japan has been in operation for more than half a century. Recently, serious damages in the network have been reported in many of the old routes. However, the Metropolitan Expressway has little-to-no of experience in managing such a situation so far. Thus, developing an appropriate management strategy focusing on maintenance is critical to the expressway. The emphasis of this study is placed on the maintenance improvement of steel viaducts, and the project aims to evaluate their marginal maintenance cost and identify the influences on the cost from uncertainties such as earthquakes and future traffic demand from an econometric perspective. The study reveals that the traffic volume of passenger cars can be identified as a significant factor, while the effect of earthquake events on the cost is not clearly pronounced. Based on the analyses, it is found that the current maintenance approach is capable of dealing with fluctuations in traffic volume, which is the most influential factor. Furthermore, an increase in the amount of maintenance works could possibly lower the maintenance costs due to economies of scale. The results also indicate that the efficiency of the current maintenance method could be improved.
Are megaprojects ready for the Fourth Industrial Revolution?
Authors: Whitmore David , Papadonikolaki Eleni , Krystallis Ilias , Locatelli Giorgio
Published: May 2020

Complex projects and megaprojects are increasingly shaped by new enabling technologies and new demands from businesses, including how people are treated when working on these endeavours. This is often referred to as the Fourth Industrial Revolution (4IR). Project leaders and practitioners are not fully leveraging the opportunities unlocked by the 4IR, and project performance shows little sign of improvement despite the highly innovative and collaborative environment that the 4IR stimulates. This paper discusses this challenge and concludes that a significant reason why these benefits are not being realised is because there is a competence gap in both the project leader and practitioner communities. These communities are attempting to deal with twenty-first-century issues using competences, toolsets and a mindset created 100 years ago. Significant developments in competences associated with the 4IR in general are required. In this paper, specific competences are proposed and justified: collaborative working including people, process and digital components; lean six sigma; and agile. Success will be to empower the people who deliver megaprojects such that they are able to deliver the planned social value to all stakeholders involved.
The Reliability of Quantifying the Pancreatic Ductus in Predicting the Operability of Pancreatic Adenocarcinomas
Authors: BATUR Abdussamet , DURMAZ Fatma
Published: May 2020

Purpose: To evaluate the quantifying of the pancreatic ductus in predicting the operability of pancreatic adenocarcinomas
Methods and Materials: We reviewed the clinical and imaging data of 30 patients (21 men, 9 women; mean age, 64.2 years; age range 41-93 years) who had histopathologically proven pancreatic head adenocarcinoma, and underwent multidetector CT for their initial nonspesific symptoms before the diagnosis was rendered. Accompanying secondary signs also were analysed.
Results: Thirty patients with pancreatic head adenocarcinoma were evaluated. Thirteen of them (43.3%) were found to be operable (Group A) and seventeen of them (56.7%) were found to be inoperable (Group B) radiologically and surgically. The mean caliber of the dilated pancreatic duct in Group A patients was 5.80 mm, and in Group B pateints was 9.15 mm (p=0.001). The ratio of pancreatic duct caliber to gland width was 0.46 in Group A and was 0.62 in Group B (p=0.001). Accompanying secondary signs such as choledoch dilatation, tumor size, and initial complaints showed no significant difference between the two groups.
Conclusion: The main pancreatic duct diameter and/or a ratio of duct to gland width can be useful in predicting the operability of pancreatic adenocarcinomas

Published: May 2020

INTRODUÇÃO: Apesar de todos os avanços das ciências da saúde, a abordagem durante o trabalho de parto segue ainda ponto de inúmeras controversas e pouco consenso baseado em evidência, dentre as quais técnicas com ou sem o uso das mãos durante o expulsivo, respectivamente hands-on e hands-off, tem ganho destaque na literatura. OBJETIVOS: investigar se o uso da técnica hands-on, em oposição à hands-off, é de fato benéfico às parturientes. MÉTODO: Revisão sistemática, nas bases de dados Pubmed, BVS, PEDro e Scielo, usando as palavras-chave birth, hands-on e hands-off isoladas ou combinadas, bem como suas variantes em português. Dados foram organizados por técnica, instrumento de medida e resultados. RESULTADOS: Dos 14 estudos que compuseram a presente revisão, apenas três foram ensaios controlados. Seis estudos apontaram a ocorrência de menos lesões quando a técnica hands-on foi utilizada, mas em todos os estudos controlados não houve diferença estatística significativa entre os resultados dos grupos. CONCLUSÃO: A técnica hands-on vem sendo utilizada ao redor do mundo, mas não há suficiente evidência de que ela de fato previna qualquer tipo de lesão obstétrica. Apesar de existirem ensaios controlados, o contraste dos resultados quanto à laceração entre os grupos controle e teste não é forte o suficiente para conclusões mais sólidas.
The Uncanniness of The Shining
Authors: ERENSOY Şirin Fulya
Published: May 2020

Stanley Kubrick’s 1980 film The Shining has been examined and analyzed countless times up until today. Even though 40 years have gone by since its release, the film’s full meaning and the events happening to the Torrance family are still unclear. The film unfolds in a limbo-like state, between dream and reality. While writing the script, Kubrick states that he was inspired by Sigmund Freud’s Das Unheimlich (1919) essay. According to Freud, things or people that arouse feelings of dread and horror belong to the realm of the uncanny. The uncanny is related to what is frightening, but more importantly it entails a duality, an ambiguity because it encompasses the familiar with the unfamiliar. This study aims to locate the uncanny elements in The Shining, while also examining how conflicting desires that have been repressed can come to the surface through the dream-like setting of the Overlook Hotel.
