Shear capacity of reactive powder concrete beams using high-strength steel reinforcement
Authors: Cao Xia , Deng Xiao-Fang , Jin Ling-Zhi , Fu Feng , Qian Kai
Published: September 2019

Reactive powder concrete (RPC) is a special type of concrete with a microstructure optimised by precise gradation of all particles in the mix to yield the maximum density. Therefore, RPC exhibits ultrahigh strength and durability. High-strength reinforcement has both high strength and good plastic deformation properties, so a combination of RPC and high-strength reinforcement can fully exploit their respective advantages. At present, there is little research on the shear capacity of beams made from RPC reinforced with high-strength steel, neither are there design guidelines for this type of structure. This paper reports on 32 full-scale shear tests of RPC beams containing high-strength steel reinforcement. The parameters affecting the shear capacity of this type of structure were studied and the major failure modes due to shear were identified.

Authors: Galembeck Eduardo
Published: September 2019

The publication of online digital content is a practice that is growing in importance in the academic world. The dissemination of academic production in an accessible way, in media that go beyond the specialized journals, is a powerful way of approximating the universities with the general public. Committed in the production of digital content aimed at Teaching Biochemistry since the end of the 90s, I had the opportunity to try different ways of disseminating these contents. In this presentation will be traced a timeline of the development of the technologies we use in the publication of digital content dissemination, starting from the first diskette given with software to three or four people interested in software presented in the SBBq's poster sessions during the 90s, to the distribution of online content at BDC, App stores and Youtube that reach over 1 million downloads and spread such content across the globe. The new technologies of information and communication have not only been effective to spread knowledge, but it has now allowing to understand how it has been used by the following their trace.

Authors: Macêdo A. P.P. , Galembeck Eduardo
Published: September 2019

INTRODUCTION: Learning Analytics tools aim to analyze data that allows the understanding of the learning process; its association with Massive Open Online Courses (MOOC) brings an opportunity for research into learning effectiveness, once MOOCs users produces digital footprints that can be used to understand their relationship with the content and environment. OBJECTIVES: To analyze the performance of users of "The Cell" in the module "Cell Chemical Composition and Biological Membranes" aiming to identify the major points that may have influenced their performance. MATERIALS AND METHODS: "Chemical Composition of the Cell and Biological Membranes" is a module of the MOOC "The Cell", a course designed into a 3D cell virtual model developed by the Laboratory of Educational Technologies of the Unicamp. The module is composed of textual content, challenge, training game, and assessment. "The Cell" has an embedded Statistical Analysis Module (SAM), an LA tool that collects data and has analysis tools focused on the student’s performance and learning process. RESULTS AND DISCUSSION: Between November of 2015 and November of 2018, SAM has registered 2858 interactions involving 1114 users in the module. The average time to perform the training game was 3.45 minutes, and there was a significant difference in the scores average comparing users who did the activity below and above the average time: 54.10 and 70.44 points, respectively. A similar result was noticed for the assessment session, users who complete the task faster scored 48.83 on average, while users who take more time scored 52.83 on average. The average score in the assessment of users who did or did not took the training game was 51.20 and 36.75, respectively. CONCLUSION: The average time spent to carry out the activities is directly related to performance; the training game acts as a preparation for the assessment, reflected in the note.

Published: September 2019

INTRODUCTION: Colorimetric methods, such as proteins and glucose quantification, and enzymatic assays are widely performed in biochemical laboratories employing spectrophotometer equipment. Even being present in most of the labs that serve undergraduate students, low cost and portable spectrophotometers can be a valuable tool in high schools and for field studies. OBJECTIVES: We have assembled and evaluated a portable spectrophotometer, inspired in some open projects freely available on the Internet. MATERIALS AND METHODS: The system was built using an RGB LED as a light source and a light detector (TSL2561). These components were placed into the ends of a cuvette holder, which was designed in FREECAD software and fabricated in a 3D printer. The data collection system was developed using an Arduino UNO microcontroller, an LCD to show the absorbance, a micro SD card to store the results, and a push button to select the LED emitted light wavelength. All components were powered by battery bank of 2000mAh. The software was written in C++, and we used Arduino IDE 1.8.6. For the equipment evaluation, we ran protein (Bradford) and glucose (Somogyi-Nelson) essays comparing the results obtained from the developed equipment with the one used in our didactic lab (Biospectro SP-22). DISCUSSION AND RESULTS: The results obtained comparing both pieces of equipment shows a correlation coefficient of 0.99 for the both methods (Bradford and Somogyi-Nelson) in test-retest. The commercial equipment demonstrated the coefficient of variation higher than 10%, while developed spectrophotometer showed values lower than 5%. The power bank was able to supply energy to the equipment up to 12 hours. CONCLUSION: These results demonstrated high reliability for the data collected from the developed spectrophotometer. Besides the low cost, compact design and high battery autonomy. The developed equipment has presented as a valuable alternative for field experiments and in-class practices of biochemistry.

Published: September 2019

Este artigo analisa a atuação de candidatos em práticas de escrita na situação de Concurso Vestibular - CV. Para tanto, tomamos como objeto de análise 126 produções textuais, realizadas por candidatos ao Curso de Letras/Campus de Campo Mourão, do Concurso Vestibular da Universidade Estadual do Paraná - Unespar, na prova de Redação das edições de 2016/2016, 2016/2017, 2017/2018. A análise dos textos baseou-se em critérios estabelecidos pelos pesquisadores, sem relação com a avaliação feita pela banca examinadora do CV. Foram observados dois aspectos: a) organização composicional e b) conteúdo temático e as particularidades que estejam ligadas a esses dois elementos. As análises revelaram que, referente ao tópico (a) os candidatos demonstraram desconhecer a composição dos gêneros discursivos solicitados, fator que acarreta na produção de textos sem marcas típicas ou, ainda, de gêneros diferentes dos solicitados. Quanto ao ponto (b), os candidatos demonstraram estar mais próximos do atendimento, uma vez que, na maioria das produções, atendem ou atendem parcialmente ao proposto pelo encaminhamento de produção textual. Os resultados acerca de (a) podem desvelar resquícios das práticas de escrita da Educação Básica que ainda não internalizaram a prática discursiva de trabalho com gêneros discursivos. Já os resultados sobre (b) indicam que o encaminhamento de produção textual contribui para a atuação dos candidatos ao disponibilizar textos de apoio que auxiliam no momento de organizar o conteúdo, dando condições de ter o que dizer
Questões de estilística no Ensino de Língua: possíveis encontros entre a prática de análise linguística e a metodologia do professor Mikhail Bakhtin
Authors: Fenilli Lays Maynara Favero
Published: September 2019

O livro Questões de Estilística no Ensino de Língua (2013), reconstituído de arquivos de Mikhail Bakhtin, traz os relatos desse filósofo da linguagem do período em que lecionava (aproximadamente entre 1942 e 1945). As anotações presentes na obra mostram o professor Bakhtin e sua metodologia de ensino de língua. Ao observá-la, é possível perceber traços convergentes com a Prática de Análise Linguística (PAL) proposta por Geraldi (1984;1991) para o ensino de Língua Portuguesa (LP). Assim, os questionamentos que nos motivam, neste estudo, são: quais as possíveis contribuições dos relatos de docência de Bakhtin para a PAL? E como tais contribuições podem balizar uma PAL dialógica? Diante disso, neste artigo, buscaremos destacar os pontos de consonância entre tais metodologias, com o intuito de ressaltar como a concepção bakhtiniana dialógica de linguagem, presente nas obras do Círculo de Bakhtin, pode permear o ensino de LP, especificamente por meio da PAL. Para tanto, desenvolvemos uma pesquisa ancorada nos pressupostos da Linguística Aplicada (MOITA-LOPES, 2006), em que cotejamos, interpretativamente, as premissas expostas por Bakhtin para sua metodologia e as premissas da PAL, buscando os diálogos possíveis a partir de uma visão sócio-histórico-ideológica de língua(gem), compreendida a partir dos conceitos de discurso, axiologia, enunciado, gêneros do discurso e estilo. Como resultado, destacamos que uma das principais contribuições da obra em estudo é a consideração do estilo como mote condutor de uma PAL explicitamente dialógica. Essa prática precisa englobar não apenas aspectos linguísticos, mas promover também análises e reflexões estilísticas e discursivas no ensino de LP.
Ler Pessoa. Dois estudos semânticos em torno de sua obra poética
Authors: Gomes Lauro , Christopulos Giorgio
Published: September 2019

Este artigo tem por objetivo geral mostrar em que medida a interpretação é um fenômeno que − como a argumentação − está inscrito na própria natureza da língua. Com base nos estudos e pesquisas em Semântica Argumentativa, partimos da hipótese de que a significação das palavras é um fator determinante não apenas para a construção do sentido dos enunciados, mas também para o estabelecimento de um possível "percurso de leitura", por meio do qual se depreende o sentido global do discurso. A fim de elucidarmos − de um ponto de vista semântico − esse recurso essencialmente cognitivo que torna possível a interação entre os homens, analisamos dois discursos literários, a saber: um fragmento do Livro do desassossego, de Bernardo Soares, e o segundo poema de O Guardador de Rebanhos, de Alberto Caeiro, ambos de autoria desses dois referidos heterônimos de Fernando Pessoa. As análises desse corpus literário mostram que a interpretação textual está subordinada à significação das palavras, às relações entre as palavras, entre os enunciados, entre as partes do discurso, bem como às instruções que o enunciado dá de sua própria enunciação.

Theoretical analysis of formation of automobile sheet roughness during temper rolling in shot-blasted rolls
Authors: Ogarkov N. N. , Zvyagina E. Yu. , Ismagilov R. R.
Published: September 2019

The methods of microgeometry formation for the surface of temper mills rolls are presented providing the required roughness of the cold rolled strip. It was established that with the electroerosion processing a more uniform structure is formed on the roll surface with a smoothly changing microrelief, compared with the mechanical action of the abrasive. The most effective abrasive for the microrelief formation on the rolls surface is cast and split steel shot. The process of interaction predominantly occurs with round-shaped shot, since the sharp edges of the split shot also become blunt during it. In the present work, the microdepression of the roll is approximated by a spherical shape. A model of roll roughness transfer to the strip was developed taking into account the type of roll processing and tempering conditions, which makes it possible to evaluate the degree of filling of a single microdepression relief at known pressures at contact of the strip with the roller, friction coefficient, roll roughness parameters and tempering modes. A quantitative estimation of reproduction of the roll roughness on the trained strip was obtained, characterized by the roughness ratio, which is the ratio of the depth of the metal flow into the strip microdepression to the depth of the roll spherical microdepression. Determination of the dimensionless pressure required for flowing a deformable metal into it was performed using the superposition method for meridian sections in two mutually perpendicular planes. The reproduction dependencies of the micro-geometry of a temper mill roll on a rolled strip on the shot size, tension, and the height parameter of roughness are presented during the tempering of stripes with various thickness, which can be used to simulate the transfer of the roll micro-relief to the rolled strip.

Critical archival research in Translation Studies: when a translation scholar becomes an archivist-researcher
Authors: Středová Kateřina
Published: September 2019

In Translation Studies, we are increasingly seeing the use of archival materials that allow translation scholars to find out more about the working conditions of translators, their motivations and relationships with authors, editors or publishers, all of whom have always influenced their work to some extent. This paper builds on the knowledge of working with archival materials and other primary sources already described in Translation Studies, and is complemented by still-useful methods of source criticism and current topics that are addressed by historians dealing with archival research. Particular emphasis is placed on the critical approach of historians specializing in composition and rhetoric who are reassessing methods of archival research and ways of writing about it, and who are encouraging scholars to adopt the stance of archivist-researcher. The paper shows and further discusses the importance of their knowledge and possible application in Translation Studies.Enfoque crítico de la investigación archivística en estudios de traducción: Cuando un investigador de la traducción se convierte en archivista-investigadorResumenEn los estudios de traducción encontramos una tendencia creciente a la utilización de materiales de archivo, que permiten a los estudiosos obtener información valiosa acerca de cuestiones como las condiciones de trabajo de los traductores o las relaciones con otros agentes (autores, editores o correctores) que siempre han influido en cierta medida en su labor. En este artículo partimos de la bibliografía disponible acerca de los métodos de trabajo con materiales de archivo y otras fuentes primarias, ya suficientemente descritos en los estudios de traducción, y la complementamos con una serie de aproximaciones novedosas en los ámbitos de la metodología de la crítica de fuentes y de las nuevas perspectivas empleadas por los historiadores en el análisis de los materiales de archivo. Hacemos especial hincapié en el enfoque crítico de los historiadores respecto de la composición y retórica, que ha permitido una reconsideración de los métodos de investigación archivística y de sus formas de escritura, alentando a los investigadores a adoptar una posición de archivista-investigador. Discutimos y tratamos de remarcar la relevancia de estos planteamientos y de sus posibles aplicaciones en los estudios de traducción.Palabras clave: historia de la traducción, contexto socio-histórico, investigación de archivo, crítica de fuentes, materiales de archivo, fuentes primariasFecha de recepción: 30/04/2019Fecha de aceptación: 30/06/2019¿Cómo citar este artículo?Středová, K.

Published: September 2019

Purpose: Early recognition of the retinopathy of prematurity (ROP), timely and appropriate treatment will contribute to the developmental process of the infant and increase the quality of life by preventing vision loss. We here by aimed to figure out the value of the blood levels of vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF-1) in infants with severe ROP requiring laser therapy.Materials and Methods: Very low birth weight infants (VLBW, ≤1500 g and gestational age ≤32 weeks) were included in the study. Blood samples for the evaluation of markers were obtained from the cord at birth for all preterms and at the same postpartum corrected age (34 weeks) for ROP and control group.Results: The mean serum VEGF level was 185.6 ± 88.1 pg/mL in the control group and 590.2 ± 97.4 pg/mL before laser treatment in the ROP group . It was decreased to 83.7 ± 25.4 pg/mL at 4 day after laser treatment in the ROP group). No significant difference was existed between the values of IGF-1 before and after laser treatment in infants with severe ROP.Conclusion: Serum VEGF and IGF-1 levels may be suggested as a sensitive marker of severe ROP. Additionally, the decrease in serum levels of VEGF after laser therapy can be used as an indicator for the efficacy of laser treatment.

Purpose: The purpose of this study was to evaluate the treatment results of the patients with Wilms tumour (WT).Materials and Methods: The clinical records of 21 children with WT treated between 2012 and 2017 were retrospectively reviewed. Age, nationality, symptoms, diagnostic and surgical methods, surgical complications, the stage of the disease, the status of neoadjuvant chemotherapy, radiotherapy status, presence of recurrent disease and histopathological  characteristics of the tumour and outcome of the patients were analyzed.Results: The female/male ratio was 2/1 and the mean age was 4.21±2.26 years. The most common physical examination finding was abdominal mass. The diagnosis was made with clinical examination and radiological investigation in 90.5% of the patients. Total nephroureterectomy was performed in all patients. The most common histopathological subgroup was classical Wilms Tumour that was detected in 81 % of the patients. 6.8 % of the patients had distant metastasis at the time of the diagnosis. The most common distant metastasis site was lungs. Overall survival (OS) of the patients was 85.7% and mean survival time was 36 months (2 months - 62 months). Advanced stage at diagnosis, presence of distant metastasis and diffuse anaplastic histology were associated with worse OS rates. Conclusion: Similar to existing knowledge on outcome of patients with Wilms tumor, our results confirmed the negative effect of advanced stage, distant metastasis and diffuse anaplastic histology on survival. Further large-scale studies investigating molecular features of the tumor are needed to decide for proper treatment and to better predict outcome.

The work proposes to study the displacement in plates, characteristics of geometry and diverse loads. The computational implementation of an 8-node hexahedral solid finite element is performed. After that, this element is enhanced through incompatible modes in order to improve the performance of the element in situations of multiaxial stresses, commonly present on plates. Then, we perform comparative analyzes with the purpose of studying the performance of the developed algorithm and compare its results with the final values of analyzes made by other authors, and with the results obtained by the modeling of the plates in commercial software. The analyzes take place in the static, linear and elastic range. It has been found that the enrichment of the low-order eight-node hexahedral solid element significantly improves its performance in plate analyzes, making it a viable alternative to the application.

The occupation of Brazilian urban areas is troubled and has occurred in an accelerated manner, different from efficient and predictable urban planning, from the macro-population point of view. Urban settlements generate social and environmental problems. Without due assistance of public authorities, the population may face some difficulties when dwelling in inappropriate regions. As a result, they start a process of instability of slopes and occupy areas which are informally called hills. This type of natural conformation is seen by geotechnics as natural slopes, which are geological units whose dynamic is variable and where several phenomena occur and may bring environmental risks. In this study, we will discuss the relationship between disordered occupation and the consequences of mass movements. In addition to that, we will examine some causes of susceptibility for the occurrence of environmental phenomena, associated risks and, as an example, we will present the measures adopted by the state of São Paulo in order to prevent the occurrence of natural disasters in areas that are inappropriate for dwelling.
Decaimento Alpha: Uma Abordagem Por Tunelamento Quântico
Authors: Silva Daniel Borges , Batista Júnior Francisco Florêncio
Published: September 2019

The present work sought to deduce the alpha decay theory based on quantum tunneling and using approximations in the resolution of the Schrödinger equation for Coulomb potential. It was possible to find the alpha decay constant analytically. One of the approaches used was the WKB method for solving differential equations, by which the Gamow factor was reached. From this point on, it was possible to identify the dependence of the decay rate with the energy of the radiation, as well as the atomic number. Besides that, we could understand the behavior of the tunneling probability with respect to some variables such as emitted particle energy and atomic number of the nucleus that decays. With this research we can help researchers in general in the study of alpha radiation.

Fabrication of Tuning-Fork Gyroscope Resonator using Directed Chemical Etching of Fused Silica
Authors: Kuznetsov V.S. , Maiorov D.V. , Andreev P.A.
Published: September 2019

The article presents the results of the experimental and practical work devoted to the study of directed chemical etching of fused silica locally exposed to ultra-short pulsed laser radiation as a way to produce sensitive elements of precision instruments of orientation, stabilization and navigation as resonators of tuning fork gyroscopes. The essence of the directed chemical etching method is presented. The created experimental setup structure and components are purposed and the laser processing and chemical etching operational modes are described. The laser processing mode obtained as a result of the experiment was used to fabricate the tuning fork gyroscope resonator. The etching rate of exposed fused silica in 5 % hydrofluoric acid is 27.5 to 68.8 µm/hour. That is much faster than the etching rate of the non-affected material. Based on this results the application of the method in the precision instruments fabrication area can be considered promising and subjected to further study.
Designing a Swarm Control Algorithm for a Group of Robots in a Persistently Disturbed Environment
Authors: Voronov E.M. , Khublarov N.O.
Published: September 2019

The paper describes the development of a software simulation package in the MATLAB 2017b environment for modelling the problem of swarm control of a group of robots moving a platform at a preset velocity to a certain target region of the motion plane when the environment is persistently disturbed. We present simulation results for solving the problem for groups of two and four robots. We plan to use the software package as a basis for implementing more complex swarm control problems, such as target interception by a group of small smart weapons. The main feature of swarm control is minimum amount of information used. This approach improves the survivability of the system as a whole. Group decision-making time virtually does not depend on the number of robots in the swarm. Each robot changes those parameters of the platform that are also affected by the actions of other robots. Each robot in the swarm uses measurements to arrive at optimum control in limited information conditions relative to the system configuration and target requirements, which is what ensures completion of the task posed. Each robot operates independently from others.
Investigating Crew Maintenance Modes for a Lunar Orbital Spaceport Station
Authors: Pugachenko S.E. , Kozedub D.A.
Published: September 2019

The investigation concerned a methodological approach to selecting crew maintenance modes for a lunar orbital spaceport station and sought to detect the most efficient mode. We assumed the orbital station characteristics to be close to those of the Lunar Orbital Platform-Gateway project that is currently scheduled in the USA. Using such a station as a base for assembling an interplanetary mission system is part of developing manned astronautics. We utilised systems analysis to conduct our investigation. We developed a mathematical model of the lunar space infrastructure, including the orbital station, transportation vehicles and launch vehicles. We assume a dual launch mission profile where a space tug attaches to a spacecraft or module in a low Earth orbit for a subsequent lunar transfer. We obtained program costs as a function of average launch frequency of the interplanetary mission system modules for two crew maintenance options. We determined a feasible range of average delivery frequency for interplanetary mission system modules, leading to long-term stay being preferable for manned missions while a system like this is being deployed.
Diffraction-Based Investigation Methods in Analysing Plastic Strain Zone Underneath Fracture Surface
Authors: Naprienko S.A. , Medvedev P.N. , Raevskikh A.N. , Popov M.A.
Published: September 2019

We used samples of the ВТ41 two-phase titanium alloy to estimate the relationship between testing temperature, KCV fracture toughness values, width of the plastic strain zone and its formation specifics. We developed an efficient method of estimating the plastic strain zone width, based on a special X-ray imaging geometry enabling a high degree of locality for measuring variations in the X-ray line broadening when moving away from the fracture surface. We studied material texture close to the fracture zone and at a distance from it, which allowed us to detect the specifics of grain reorientation, in particular, texture diffusion and an increase in the concentration of basal and prismatic planes parallel to the fracture surface as a result of plastic strain and dislocation saturation. We hypothesise that pole density in the [0001] region grows due to the [1012]-oriented grain slip, while in the region around [1010] pole density grows due to slip of the grains whose orientation is close to [1120]. We verified our X-ray texture analysis data by texture analysis via electron backscatter diffraction (EBSD).
Taniec w turystyce w perspektywie antropologicznej – wprowadzenie do problematyki
Authors: Banio Adrianna , Malchrowicz-Mośko Ewa
Published: September 2019

Taniec odgrywa ważną rolę we współczesnym przemyśle turystycznym. Obecna moda na taniec stwarza wielkie możliwości dla turystyki kulturowej. Należy jednak pamiętać, że istnieje ogromne niebezpieczeństwo zatracenia najważniejszego sensu tańca przez komercjalizację i spłycanie jego istoty. Omawiana w artykule turystyka taneczna to podróże związane z tematem tańca, polegające na poznawaniu tego fenomenu kulturowego w miejscach, w których narodziły się dane style taneczne lub w których pełnią one ważną rolę dla narodu, czy też cieszą się dużą sympatią społeczności lokalnej. Artykuł stanowi wprowadzenie do problematyki turystyki tanecznej w kontekście antropologicznym. Zaprezentowano w nim potencjalne atrakcje związane z tańcem w perspektywie turystyki kulturowej i sportowej. Praca ma charakter przeglądowy oraz opisowy. Zastosowano w niej metodę analizy literatury przedmiotu oraz doniesień popularnych.
Miasto w cieniu muzeum. Problemy rozwoju turystyki w Oświęcimiu
Authors: Kruczek Zygmunt , Nowak Agnieszka
Published: September 2019

W artykule opisano problemy rozwoju turystyki w Oświęcimiu, miasta, którego wizerunek zdominowany jest przez miejsce ludobójstwa KL Auschwitz-Birkenau. W opracowaniu skoncentrowano się na prezentacji wyników badań nad wizerunkiem miasta. Dodatkowym celem jest przedstawienie działań prowadzących do zmiany niekorzystnego wizerunku Oświęcimia – „miasta w cieniu muzeum”. Są one zawarte w Strategii rozwoju turystyki w Oświęcimiu na lata 2018–2030 (2018), opracowanej z udziałem autorów niniejszego artykułu. W tekście dokonano również analizy walorów turystycznych oraz zagospodarowania turystycznego pod kątem wykorzystania ich w tworzeniu uzupełniającej oferty dla odwiedzających Państwowe Muzeum Auschwitz-Birkenau.
„Jak ktoś uwierzy, to wtedy jest jemu łatwiej”. Koncepcja pomocy dla kobiet rezygnujących ze sprzedaży usług seksualnych na przykładzie katolickiego Ośrodka dla dziewcząt i kobiet zagrożonych prostytucją i chcących porzucić jej uprawianie
Authors: Surmiak Adrianna
Published: September 2019

Literatura przedmiotu w niewielkim stopniu dotyczy pomocy instytucjonalnej kobietom porzucającym prostytucję. Szczególnie brakuje omówienia perspektywy katolickiej, która bywa – jak w przypadku badań Sharon Oselin i Ronalda Weitzera – łączona z perspektywą radykalnego feminizmu. W artykule rekonstruuję koncepcję pomocy dla byłych pracownic seksualnych na przykładzie katolickiego Ośrodka dla dziewcząt i kobiet zagrożonych prostytucją i chcących porzucić jej uprawianie. Analizuję również poglądy jego personelu odnośnie prostytucji, prostytutek i tego, jak powinny one funkcjonować po rezygnacji ze świadczenia usług seksualnych. Swoje rozważania opieram na badaniach etnograficznych, które prowadziłam (z przerwami) w latach 2005–2016.
Praca w NGO jako (re)produkcja statusu klasowego. Na przykładzie organizacji zwalczających prostytucję w jednej z indyjskich metropolii
Authors: Romanowicz Anna
Published: September 2019

Artykuł jest oparty na etnograficznych badaniach terenowych i dotyczy działalności organizacji pozarządowych zwalczających prostytucję i sex-trafficking w jednej z indyjskich metropolii. Autorka twierdzi, że pracownicy organizacji konstruują obraz swoich beneficjentów jako ofiar patriarchalnej opresji w celu podkreślania dystynkcji klasowych pomiędzy nimi samymi (członkami klas średnich) a beneficjentami (członkami klas niższych). Dokonuje także analizy postrzegania Innego spoza systemu NGOsów. Na tej podstawie postuluje ona rozszerzenie granic orientalizmu (Buchowski 2006), gdzie Inny wpisywany jest nie tyle w dychotomię geografii wyobrażeniowej na linii „Wschód–Zachód” (Said 1979), ale jest konstruowany właśnie w oparciu o dystynkcje klasowe (Buchowski 2006).
DIMENSIONS OF SERVICE QUALITY IN GLAMPING
Authors: Vrtodušić Hrgović Ana-Marija , Cvelić Bonifačić Josipa , Milohnić Ines
Published: September 2019

Purpose – Service quality plays an important role in improving quality and competitiveness in
glamping, an innovative and novel form of accommodation in campsites. Therefore, this paper
strives to present the dimensions of service quality in glamping from the perspective of two target
groups: guests and campsite managers.
Methodology – Research was based on a structured questionnaire, designed especially for each
target group (guests and campsite managers). The study included 120 managers and 130 guests.
Surveys were conducted in 2017 and 2018 using an on-site questionnaire for managers and both
an on-site and online questionnaire for guests. The data were analysed using methods of descriptive
and inferential statistics.
Findings – Research results indicate that managers and guests alike attach importance to the quality
elements of glamping service and glamping accommodation facilities. Both target groups agree
that friendly staff, professional staff and cleanliness have the greatest role in ensuring glamping
service quality, and attractive and well-maintained natural environment, equipment and fittings,
and innovative and appealing appearance, in glamping accommodation quality. Results also show
that the importance scores given by managers are somewhat higher than those given by guests, in
all quality elements that were rated with regard to glamping service and glamping facilities.
Contribution – This study makes a contribution to theory and application. From a theoretical
perspective, the study contributes by broadening the literature by identifying quality elements in
glamping from the perspective of guests and campsite managers. From an application perspective,
the results of research contribute by highlighting the quality elements that are important to guests
and that should be taken into consideration when designing a product/service as well as in the
service provision process.

Automation of tracking solar panels has been made using LDR sensors, photodiodes and photodiode arrays. This research was conducted to find out which system with sensors used in solar panel tracking systems. The tracking system consists of four sensors that are placed parallel to the panel and drive system using a servo motor. The sensor and servo motor control system is performed using an Arduino microcontroller. Based on the results of the study, tracking systems using LDR sensors have an accuracy of 95.18%, tracking systems using photodiode sensors have an accuracy of 90.72%, and tracking systems using photodiode array sensors have an accuracy of 94.51%. These results indicate an accurate system is a system using the LDR sensor. However, the power consumption of the system with a LDR is quite large, which is 0.7 watts compared to the system power consumption with a photodiode of 0.63 watts and a system with a photodiode array of 0.59 watts. A good system is a tracking system using a photodiode array sensor because it has a slightly lower accuracy than the LDR but has more efficient power consumption. This study also compares the system output power without tracking and tracking systems. The use of tracking systems makes the panel output power increase by 0.22 watts compared to static systems.
