Published: June 2021

Purpose: Coronavirus disease 2019 (Covid-19), first reported in December 2019 in Wuhan, China, has become a pandemic. Chest imaging is used for the diagnosis of Covid-19 patients and can address problems concerning Reverse Transcription-Polymerase Chain Reaction (RT-PCR) shortcomings. Chest X-ray images can act as an appropriate alternative to Computed Tomography (CT) for diagnosing Covid-19. The purpose of this study is to use a Deep Learning method for diagnosing Covid-19 cases using chest X-ray images. Thus, we propose Covidense based on the pre-trained Densenet-201 model and is trained on a dataset comprising chest X-ray images of Covid-19, normal, bacterial pneumonia, and viral pneumonia cases.
Materials and Methods: In this study, a total number of 1280 chest X-ray images of Covid-19, normal, bacterial and viral pneumonia cases were collected from open access repositories. Covidense, a convolutional neural network model, is based on the pre-trained DenseNet-201 architecture, and after pre-processing the images, it has been trained and tested on the images using the 5-fold cross-validation method.
Results: The accuracy of different classifications including classification of two classes (Covid-19, normal), three classes 1 (Covid-19, normal and bacterial pneumonia), three classes 2 (Covid-19, normal and viral pneumonia), and four classes (Covid-19, normal, bacterial pneumonia and viral pneumonia) are 99.46%, 92.86%, 93.91 %, and 91.01% respectively.
Conclusion: This model can differentiate pneumonia caused by Covid-19 from other types of pneumonia, including bacterial and viral. The proposed model offers high accuracy and can be of great help for effective screening. Thus, reducing the rate of infection spread. Also, it can act as a complementary tool for the detection and diagnosis of Covid-19.

Authors: Ghorbani Farzaneh , Seyedi Somayyeh , Montazerabadi Alireza
Published: June 2021

Magnetic particle imaging was introduced in 2005 as a new tomographic medical imaging modality and is still under development. Magnetic particle imaging determines the spatial distribution of magnetic nanoparticles by their interaction with an external excitation magnetic field. Therefore, there is no ionizing radiation dose in this trace-based modality. Magnetic nanoparticle imaging provides characteristics, including high spatial and temporal resolution, high sensitivity, expected from an ideal imaging method, and it is also an inherently quantitative method.
In this paper, the properties of magnetic fields and particles used in Magnetic particle imaging, as well as its applications are discussed.

Published: June 2021

Synthetic colors have advantages in comparison to natural colors, but they cause cancer, attentiondeficit hyperactivity disorder, immune system suppression and vitamin deficiency. In the present study, authorized and unauthorized synthetic colors in saffron barbecued chicken from meat shops and restaurants in Babol city have been identified by thin-layer chromatography. Fifty samples of saffron barbecued chicken from meat shops and restaurants in Babol city have been collected from July to September 2019. Out of 50 samples, 20 had natural color, while 27 and 3 samples contained authorized and unauthorized synthetic colors respectively. According to the Institute of Standards and Industrial Research of Iran, the application of synthetic colors is banned in saffron barbecued chicken. Therefore, 40% were consumable and 60% were inconsumable, out of which 54% contained quinoline yellow and 6% had tartrazine. About 58.06% and 63.15% of samples from meat shops and restaurants were inconsumable, respectively. There were no significant differences regarding the frequency of the evaluated colors between samples from meat shops and restaurants (p>0.05). Based on the results, it is essential that the presence of synthetic colors is traced constantly and more strictly in food products and that the perpetrators receive more serious punishment.

Published: June 2021

This study examines the effect of capital market development on the economic growth of Nigeria using data on Real Gross Domestic Product as a proxy for economic growth while capital market variables constitute the independent variables. This includes Market Capitalization, All Share Index, Number of Listed Securities and the number of listed companies The study adopted an expost-facto research design which utilized secondary data for the period 1983 -2016. While an Augmented Dickey-Fuller unit root test was used for preliminary analysis; an Autoregressive Distributed Lag (ARDL) was used for the model estimation. .A combination of ARDL bounds test for co-integration, ARDL short and long run error correction models were used for estimation. All the tests helped to confirm the integrity of our models. Findings of the study indicate that, the Number of listed Securities and All Share Index maintained a significant relationship with economic growth in Nigeria both in the short and long runs. Based on the findings of study it was recommended that government should help to remove all impediments to stock market development in the form of tax, legal and regulatory barriers as they act as disincentives to investments in the capital market. Again, government should help to maintain policy consistency in the pursuit of growth in the Nigerian capital market. By so doing, counter developmental policies should not be allowed to crowd out the gains of capital market development and by extension on economic growth in the long run. Lastly the government should find ways and means of boosting the confidence of investors to retain their portfolio investments.
Exploring the Application of Interpretive Description in Chronic Illness: A Scoping Review
Authors: Marrocco Anna M. , El-Masri Maher M.
Published: June 2021

Background and Purpose

Chronic illness is a complex condition that affects over one billion people. To develop a deeper insight of the needs of this patient population, interpretive description uses disciplinary knowledge as the source of understanding. This methodology is a pragmatic approach to research without focusing on a strict methodological directive. The aims of this scoping review are twofold, (a) to describe the findings of studies that have used Thorne's interpretive description to research chronic illness and (b) to discuss the application of interpretive description in clinical research. Thereby, showing interpretive description as a valuable tool to advance nursing knowledge and patient care.

Methods

The methodological framework for this review was based on the Johanna Briggs Institute guidelines for scoping reviews.

Results

To develop an understanding of interpretive description, it is essential to examine the results of studies which have applied the methodology. Our scoping review showed that researchers utilizing interpretive description identified four common challenges experienced by individuals living with chronic illness: symptom management, education and knowledge, supportive care, and cultural disadvantages. By demonstrating how interpretive description is applied, it shows how it can be used to understand and interpret clinical phenomena to improve practice.

Implication for Practice

This scoping review demonstrates how interpretive description was used to develop knowledge about chronic illness. The premise of interpretive description is that disciplinary knowledge offers a sufficient foundation to develop meaningful research to support health practices. By approaching research from a disciplinary perspective, new knowledge can be discovered to complex health problems.
Critical Ally and Critical Friend: stepping stones to facilitating practice development
Authors:   Galway Clinic, Doughiska, Galway, Ireland, hardiman Michele , Dewing Jan ,   Canterbury Christ Church University
Published: June 2021

Background: The Critical Ally and Critical Friend are two models in the early stages of developmental testing as part of a doctoral research programme. Together with the Critical Companionship model, they offer a theoretically coherent framework for developing expertise in the facilitation of learning about practice from within the workplace. The two new models are sequentially related models underpinned by key principles of practice development and critical social theory. Unlike Critical Companionship, the Critical Ally and Critical Friend models are aimed at novice and proficient practice developers respectively; we argue that, because of their design, they can offer stepping stones to Critical Companionship. Together, the three models offer a pathway for practice developers and practitioners to gain, in a systematic way over a longer timescale, a repertoire of facilitation skills and to build expertise. Aims: To describe the two new models and demonstrate their theoretical coherence with Critical Companionship. We also invite other practice developers and facilitators of workplace learning to debate the coherence of the two new models and the overall pathway, and to contribute to testing the models in a range of workplaces. Implications for practice: The two new models, when used in conjunction with the Critical Companionship model, offer a pathway for developing facilitation expertise within practice development The models offer a broad based introduction to learning in and from practice, which could be useful for preceptors, mentors, clinical supervisors and facilitators at all levels from novice to proficient As the three models offer a pathway, they could be useful as part of strategic workforce development, and learning and development planning The models offer a potential new midrange theory that can contribute to developing practice development knowledge
An innovative toolkit: increasing the role and value of patient and public involvement in the dissemination of research findings
Authors:   University of Leeds, England, McNichol Elaine , Grimshaw Paul ,   University of Leeds, England
Published: June 2021

Background: Evidence of patient and public involvement (PPI) in health research dissemination is weak and the development of mechanisms to assist the adoption and diffusion of PPI outcomes into research findings, patient experience and clinical practice is at an early stage. Aim: This paper seeks directly to address this weakness by increasing researchers’ awareness and understanding of the potential value of PPI in dissemination and identifying practical strategies that could improve the quality and impact of PPI by connecting the process with the wider innovation literature on adoption and diffusion. The toolkit: Guidance for these strategies is provided in the form of a toolkit that elevates the importance of PPI in dissemination of research and blends it with good practice in diffusion of innovations. It highlights how planning for PPI and dissemination at each stage of the research cycle facilitates the diffusion of research findings, while generating a culture of knowledge exchange with important stakeholders. Conclusions: Establishing and improving PPI dissemination in the research process has similarities with introducing any new innovation into a social context. Therefore, understanding and integrating insights from the literature on adoption and diffusion and linking them to PPI and the research cycle provides a different frame of reference for developing our approach in healthcare. Here we connect PPI to the adoption literature and suggest that a strong focus on the social nature of innovation will increase the reach and impact of research dissemination. This challenges the traditional research culture and suggests a need for a more open and continuous web of PPI relationships that are characterised by well balanced, timely contact and consist of appropriate and flexible interactions, planned into the whole research cycle. Implications for practice: This paper highlights the value of taking a structured approach to PPI and the importance of investing time in developing productive PPI relationships at the beginning of a project. Similarly, dissemination should be planned for and undertaken at key points and in different ways throughout the process in order to maximise its potential impact. The key implications are the value of: Widening the scope of PPI dissemination into the whole research cycle Opening up routes to improved research impact through better quality patient involvement Challenging the stereotypical relationship between researcher and patient Introducing innovation adoption concepts into PPI dissemination

Authors:   MidCentral District Health Board, Palmerston North, New Zealand, Blair Wendy , Wood Sue ,   MidCentral District Health Board, Palmerston North, New Zealand
Published: June 2021

Background: Three central North Island District Health Boards developed a collaborative partnership to create an education framework to improve workplace learning by nurses. A Joint Nursing Speciality Education Project Group was formed to explore frameworks and models of care that would support and enhance nursing practice. Aims and objectives: The aim of this article is to reflect critically on the process of leading the project group during the development of a nursing framework that would encompass a holistic view of education and meet the needs of each participating health board. The article also examines the issues encountered, which included the difficulties of working with nurses from different organisations in different geographical locations. Conclusions and implications for practice: The process of developing the Person-Whānau (Family) Centred Nursing Framework was a team effort and working collaboratively across health boards has been extremely rewarding. We faced workload and geographical challenges in trying to get the whole group together but the chance to develop a framework that has the ability to improve patient outcomes has been exciting and the relationships we have forged along the way with members of the project group have been positive.
Using stories within practice development
Authors:   Foundation of Nursing Studies, London, England, Odell Jo
Published: June 2021

I chose to write about patient stories as a key influence in my work because of my personal experience of using these. This experience has inspired me to encourage and enable others to use this approach to help them understand better the people they are caring for and their experiences of healthcare. Being introduced to patient stories I was introduced to the idea of patient stories when I was a participant on the Gerontological Nurse Development Programme in 2002. This three year practice development project, a collaboration between the Royal College of Nursing (RCN), the University of Portsmouth and the local acute and community older persons’ services, was aimed at developing nurses and their practices. The RCN facilitator I was working with encouraged me to ask patients I was caring for some unusual questions such as, ‘tell me about your life’ and ‘what prevents you doing what you want to do?’ By listening to the responses I was able to start moving from seeing the patient in one dimension to seeing the whole person living in the context of their family and community, not just their medical condition. Subsequently, I wrote about my experience and the learning I gained from this simple but powerful experience (Odell, 2004). As a result, I started to invite nurses I was working with to ask their patients the same questions as I had used. For example, I was mentoring a student nurse who had assessed an older person on admission to the community hospital. I asked the nurse to return to the patient the following day and ask questions about her life and likes and dislikes, as opposed to the standard medically oriented questions we traditionally ask. The nurse told me that doing so had enabled her to learn more about the person she was caring for and therefore to care for her in a more individualised way.

Published: June 2021

Esta investigación tiene como objetivo principal identificar la relación de los mensajes de texto en la comunicación de acciones de endomarketing y su influencia en el compromiso organizacional del cliente interno. Para ello, fue hecha una revisión de la conceptualización en torno al compromiso organizacional, a partir del modelo de Allen y Meyer, y su importancia para la mejora de la empresa. Seguidamente fue estudiado el tema de endomarketing o marketing interno en relación con la comunicación de acciones internas, los servicios de mensajería y su relación con el compromiso. La investigación, dirigida a los colaboradores de la Clínica Ricardo Palma durante la actividad de Olimpiadas 2017 apunta a comprobar una asociación negativa entre el compromiso y los servicios de mensajería, pese a ser un canal bastante cercano a un usuario. Haciendo uso de un estudio de caso con enfoque cuantitativo concluyente, se evaluó un total de 142 colaboradores, a través de encuestas. En ambos casos se evaluó por medio del cuestionario de compromiso de Allen y Meyer realizado por María Bohnenberger (2005) sobre la asociación de endomarketing con compromiso; además se hizo uso de la percepción de los canales de comunicación de Herrera (2011), todo bajo escala Likert. La parte final de la estructura corresponde a la descripción del caso, análisis y resultados, donde se buscará demostrar el grado de relación de los servicios de mensajería (SMS) como medio idóneo y su incidencia en el incremento del compromiso.

Authors: Komang Nadia Eprillia Sary Darma Ni , Adi Anak Agung Ayu Mirah , Winaya Ida Bagus Oka
Published: June 2021

Viroterapi adalah pemanfaatan virus onkolitik untuk pengobatan kanker. Virus Newcastle Disease (ND) merupakan salah satu virus onkolitik, yakni virus yang mampu bereplikasi dan membunuh sel tumor tanpa menimbulkan kerusakan pada sel sehat. Virus ini dikatakan mampu bereplikasi hingga 10.000 kali lebih cepat pada sel kanker. Penelitian ini bertujuan untuk mengetahui gambaran histopatologi (HP) paru-paru tikus penderita fibrosarkoma yang tidak diviroterapi dan tikus penderita fibrosarkoma yang diviroterapi dengan virus ND isolat Tabanan-1/ARP/2017. Penelitian ini menggunakan tiga perlakuan dengan tiga ulangan disetiap perlakuan. Perlakuan P0 (kontrol negatif) adalah tikus yang tidak menderita fibrosarkoma, P1 (non-viroterapi) adalah tikus penderita fibrosarkoma yang tidak diviroterapi, dan P2 (viroterapi) adalah virus penderita fibrosarkoma yang diviroterapi menggunakan virus ND dengan dosis 0,5 mL/2^9 HA Unit. Variabel gambaran HP paru-paru yang diamati untuk membandingkan antara ketiga perlakuan adalah hemoragi, kongesti dan edema. Data hasil pengamatan terhadap masing-masing variabel dilakukan skoring sesuai dengan tingkat keparahan lesinya, lalu dianalisis menggunakan uji Kruskal-Wallis dan jika berbeda nyata dilanjutkan dengan uji Mann-Whitney. Dari hasil penelitian ini didapatkan bahwa tidak ada lesi ditemukan pada paru-paru tikus P0. Gambaran histopatologi paru-paru pada P1 menunjukkan adanya lesi hemoragi, kongesti dan edema yang dominan, sedangkan pada P2 hanya lesi kongesti yang dominan tanpa adanya hemoragi. Hasil pengamatan menunjukkan, viroterapi menggunakan virus ND efektif untuk mengurangi lesi hemoragi namun kurang efektif untuk lesi kongesti. Secara keseluruhan, lesi pada kelompok viroterapi menggunakan virus ND lebih ringan jika dibandingkan dengan tikus yang tidak di viroterapi.
The Transparent Eyeball of the Nation: Walt Whitman’s Imagined Nation in “Song of Myself”
Authors:   College of Arts, King Saud University, Saudi Arabia, Alghamdi Mohammed Ghazi
Published: June 2021

This paper provides a textual analysis of Walt Whitman’s “Song of Myself”, revealing its significance as a national poem. The paper argues that Whitman’s "Song of Myself" breaks literary and political limits, challenging the sovereignty of the nation. By examining "Song of Myself" in the six different editions of Whitman’s Leaves of Grass, this paper will further analyze Whitman’s style and his speaker as representations of the limitations and sovereignty of literary tradition and the politics of his nation. By “politics,” I refer to the religious, political, and social doctrines that shape the nation. By “literary,” I mean the traditional literary style of writing, such as the poem’s form, scope, and subject.

The conversion of metal-modified (Fe, Co) sawdust into magneto-sensitive porous composites using thermal carbonization process in an inert atmosphere was successfully achieved. The as-prepared samples were characterized using nitrogen adsorption, X-ray diffraction, scanning electron microscopy and thermal analysis methods. The obtained results show that the structural and morphological characteristics of the obtained composites depend strongly on the metal precursor’s types. All samples exhibited a good magnetic property and can be easily separated from liquids by an external magnet.
Saturação metafórica
Authors: Dienstbach Dalby
Published: June 2021

Este trabalho investiga o papel de um aspecto específico da linguagem metafórica – exatamente, a sua saturação (p. ex., DUNN, 2011) – na organização cognitiva dos tipos de discurso. Esta investigação cumpre (i) a identificação de expressões metafóricas em textos identificados com diferentes gêneros, quais sejam letras de canção e charges; e (ii) a análise da saturação metafórica dessas expressões em função de aspectos prototípicos desses gêneros. Os resultados mostram que o funcionamento da saturação metafórica depende do tipo de discurso. Enquanto que, em textos do discurso literário, esse aspecto se acomoda, preferencialmente, no plano intratextual (dentro de um único texto), em textos do jornalismo crítico, embora se estruture de modo situado em nichos metafóricos (VEREZA, 2007; 2010a), esse aspecto pode se estender no plano intertextual.

O presente relato visa abordar os desafios da metodologia participativa diante da pandemia de COVID-19, bem como as perspectivas futuras para a comunicação comunidade-universidade dentro da Universidade Federal de Santa Catarina (UFSC). O Ateliê Modelo de Arquitetura e Urbanismo (AMA) - Escritório Modelo de Arquitetura e Urbanismo (EMAU) da UFSC - atua como uma ferramenta de acesso à moradia digna, através da arquitetura participativa como comunicação dialógica. A partir da experiência do projeto de extensão com a comunidade da Ponta do Leal, localizada no bairro Balneário Estreito em Florianópolis/SC, busca-se desenvolver atividades em conjunto aos moradores, adaptando a metodologia de acordo com o contexto inserido. Nesse sentido, a troca de saberes é fundamental para garantir a autonomia dos usuários. Para tanto, o relato aborda de maneira crítica o andamento do projeto participativo, apresentando os alcances e as barreiras encontrados nessa prática. Assim, por meio de uma análise objetiva, pretende-se colaborar para a práxis dialógica, a reflexão sobre a formação do Arquiteto e Urbanista e qual o seu papel social, contribuindo para o desenvolvimento de uma universidade socialmente comprometida.
Transosseous Tie Fixation Using Krackow Sutures and Bone Tunnels in a Comminuted Fracture of the Upper Pole of the Patella: A Case Report
Authors: Baik Jong Seok
Published: June 2021

Comminuted fractures of the patella mostly occur at the inferior pole and require appropriate reduction and fixation to restore the extensor mechanism. Conventional methods such as tension-band wiring are not enough to gain proper fixation strength. Numerous methods have been reported, including circumferential cerclage wiring, osteosynthesis, and suture anchors depending on the fracture pattern. Herein, the author reports a relatively rare case of a comminuted fracture of the upper pole of the patella, for which we used augmented Krackow sutures in the quadriceps and fixation with tying of the suture limbs through patellar bone tunnels. Satisfactory results were obtained in terms of reduction and extensor mechanism recovery.
KARL POPPER VE YANLIŞLANABİLİRLİK İLKESİ
Authors: MERKİT Nuriye
Published: June 2021

Bu makalenin amacı Karl Popper’ın yanlışlanabilirlik ilkesine dair görüşlerini açığa çıkarmaktır. Popper’dan önceki düşünürler, hangi tür önermelerin doğrulanabilir olduğunu bulmaya çalışırken Popper, yanlışlanabilir olan önermeleri araştırarak yerleşik bilim anlayışına yeni bir bakış açısı getirmiştir. Eleştirel ve yenilikçi olan bu bakış açısıyla o, sözde bilimleri bilimden ayırmaya çalışmıştır. Popper, söz konusu ayırma işlemini mantıkçı pozitivistler gibi anlamlılık – anlamsızlık çerçevesinde değil, bilimsel olan ile bilimsel olmayan arasında yapmıştır. Çünkü ona göre bilim ve metafizik arasında mantıkçı pozitivistlerin iddia ettiği gibi keskin bir sınır olmayabilir ve sözde bilimler bile anlamlı olabilir. Bir önermenin bilimsel bir nitelik kazanması onun mantıksal kurgusunun sınamaya ve bu sınamalar sonucu yanlışlanabilmeye imkan sağlayıp sağlamamasına bağlıdır; çünkü yanlışlanma imkanı olmayan bir önerme, sınanabilir olsa da bilgi içeriği taşımaz. Bilgi içeriği taşımayan bir önermenin ise bilimsel olup olmamasının bir anlamı yoktur.
The problem of using English reading strategies perceived by Thai EFL students

Published: June 2021

It is recognized that reading ability is essential for Thai EFL students and English reading is perceived as a difficult task among them. To understand the difficulty experienced by the students while reading English text, this study hence aimed at investigating problems of using English reading strategies perceived by Thai EFL students as well as providing suggested reading instructions for Thai lecturers to cope with the emerging problems. This study employed a mixed-method design. The participants of the study were 412 Thai EFL students who, in this study, were also considered as Gen Z students at a large-size university in Bangkok, Thailand. The participants were asked to complete an online questionnaire on 4-point Likert’s scale, which was adapted from Aebersold and Field (1997). Moreover, 10 students were recruited for two focus group interviews. The results revealed that Thai EFL students experience difficulties in using English reading strategies when they have to skip unknown words during the first reading (mean = 2.67, SD = 1.01) followed by varying reading speed rates according to the type of the reading passage (mean = 2.66, SD = 0.97), and guessing the meanings of unknown words by using the context clues (mean = 2.59, SD = 0.92) respectively. Based on both quantitative and qualitative results and personality traits of Thai Gen Z, suggested reading instructions including guided reading, improving student’s vocabulary knowledge and reading comprehension, technology-blended classroom and critical reading were purposed.

Published: June 2021

In this study, the optimum dimensioning of a reinforced concrete retaining wall that meets the safety conditions under static and dynamic loads in terms of cost has been performed using Jaya algorithm, which is one of the metaheuristic algorithms. In the optimization process, reinforced concrete design rules and ground stress, sliding and overturn tests have been determined as design constraints for the safe design of the retaining wall. While 5 cross-section dimensions of the retaining wall are defined as the design variable, the objective function is targeted as the total cost per unit length of the retaining wall. In the study, optimum results are also presented by examining the changes of the toe projection length of the retaining wall, which is one of the design variables, narrowing between 0.2-10 m. The design variables minimizing the objective function were found via Jaya algorithm that have single-phase. In addition to achieving optimum dimensioning results in terms of safety and cost with the optimization method used as a result of the reinforced concrete design made by applying the rules of the regulation on buildings to be constructed in earthquake zones, the change in cost in seismic and static conditions was examined.

Published: June 2021

In this study, the effect of different types of slabs on dynamic characteristics of structures under the lateral loading was investigated. For this purpose, four different types of slabs namely, beamed slab, flat slab, one way ribbed (hollow core) slab and waffle slab have been modeled in buildings having 3, 4 and 5 storeys with the same geometric dimensions, in accordance to design and construction requirements (TS 500) and Turkish building seismic codes (TBDY, 2018). Seismic analysis calculations of the modeled buildings were done using the equivalent seismic load method. The assumed local soil class was taken from the geotechnical report as ZD. As a result of the analysis, natural periods, base shear forces, maximum horizontal displacements and relative storey drifts of the buildings were compared. Seismic analysis and calculations of the buildings were completed using SAP2000 finite element software.

A large proportion of road and railway bridges, present in Turkey served for many years, have been completed their service life or will soon. Continuing safety and sustainability of these bridges under traffic loads have been of great increasing importance to roadway and railway transportation line to be continuous servicing. In addition, the demolition and reconstruction of bridges that have reached the end of their service life or are nearing completion will have a negative impact on the country's economy. All of these requirements' detailed examination of bridges in order to provide economical and safe service, considering current vehicle loads and earthquake loads. The Mahmutçavuş Bridge is investigated as a simply supported continuous composite roadway bridge at this work. The finite-element model of the bridge is constituted by site investigation and measurement. Different truckloads using for the design of the bridge are determined, and static analysis of the bridge is conducted. Seven earthquake records are scaled for two different earthquake design spectrums. The nonlinear time-history analyses are conducted, considering Δ-δ effects. The performance of the bridge for varying truckloads and earthquake loads is investigated, and results are discussed in detail.
