Authors: Наумов В.А. , Великанов Н.Л. , Тришина А.В.
Published: December 2020

Цель статьи – получить эмпирические зависимости для характеристик трехплунжерных противопожарных насосов (ТПН), необходимые для автоматизации расчетов систем тушения пожаров на судах с применением распыленной морской воды. Задачи исследования: проверка непротиворечивости данных испытаний; определение расчетных зависимостей производительности ТПН, к.п.д., затраченной мощности от давления. Проведенный анализ результатов испытаний ТПН подтвердил возможность использования предложенных зависимостей в инженерных расчетах. Данные измерений удовлетворительно согласуются с результатами расчетов, за исключением к.п.д. Отклонение экспериментальных точек от эмпирических зависимостей, скорее всего, связано с занижением значений затраченной мощности на испытаниях при небольших давлениях. Предложено для оценки к.п.д. использовать ранее полученную типовую зависимость. Построены графики для характеристик насоса NP25/41-170S. Пример расчета рабочей точки насосной установки с использованием приближенной гидравлической характеристики водяной пожарной системы судна показал высокую эффективность предложенных методик.

The purpose of the article is to obtain empirical dependences for the characteristics of three-plunger fire-fighting pumps (TFP), which are necessary for automating calculations of fire extinguishing systems on ships using sprayed seawater. Research objectives: checking the consistency of test data; determining the calculated dependences of the TFP performance, efficiency, power expended on pressure. The analysis of the TFP test results confirmed the possibility of using the proposed dependencies in engineering calculations. The measurement data are in satisfactory agreement with the results of calculations, with the exception of efficiency. The deviation of experimental points from the empirical dependences is most likely due to an underestimation of the power consumed during tests at low pressures. It is proposed to use the previously obtained typical dependence to estimate the efficiency. Graphs are plotted for the characteristics of the NP25/41-170S pump. An example of calculating the working point of a pumping unit using the approximate hydraulic characteristics of the ship's water fire system showed the high efficiency of the proposed methods.
Ochrona prawna zaufania przez informację przy świadczeniu usług finansowych

Legal protection of trust in the area of financial services is a very important subject, which finds reflexion in contemporary law, both European as well as national one. Financial services constitute, as a matter of fact, products of trust, which means that the evaluation of their properties, the relation of the quality to the price, the risk resulting from concluding the contract become known to the non-professional buyer after concluding the contract. In such circumstances, the non-professional party is forced to act in trust to the information received from the financial institution, and failure to provide the buyer with the obligatory information or providing it in an non-transparent form may lead to appearance of disturbances in the efficient functioning of market mechanisms, on which the price of the service should reflect the information about its quality and risks connected with it. The article provides an insight into the area of trust and precontractual information duties as an institution addressed to protect parties’ trust one to another. The scope of the article covers the area of financial services, in particular credit and investments.
Zjawisko multicentryczności systemu prawa z perspektywy koncepcji integracyjnej
Authors: Kotowski Artur
Published: December 2020

The paper presents the theory of legal system polycentricism from a new perspective, i.e. the one integrating essentially contradictory concepts which explain this phenomenon in the context of the Polish jurisprudence. Apart from attempting to establish “common features” of these well-known concepts explaining the essence of polycentricism in the legal field, the presented point of view pertains to defining the relationship between the phenomenon of polycentricism from the legal discourse theory perspective and the Luhmann’s systems theory. The paper aims to prove the thesis that at present the legal system is internally taking on (transforming into) the heterogeneous type of internal structure due to interaction with already polycentric non-juristic domain, i.e. the social one.
Modes of Identification Within a Language Learner-Led Community of Practice
Authors:   Kanda University of International Studies, Chiba, Japan, Hooper Daniel
Published: December 2020

Although the importance of communities for social learning within self-access centers has been recognized over the last decade, there has yet been little research exploring student-managed communities in a self-access learning center (SALC). This short pilot study investigates the ways in which members identify with the community of practice (Wenger, 1998) of a student-led learning community within a university SALC. Five members of the Learning Community (LC), an English conversation community, were interviewed three times over the course of one semester about their language learning histories and their experiences in the LC. This data was analyzed inductively and subsequently categorized according to Wenger’s (2010) modes of identification – engagement, imagination, and alignment. The findings of the study indicated that members’ identification with the practice of the LC was connected to a desire for an accessible learning environment, attaining membership in an international imagined community of English users, and the ability to negotiate sociocultural norms for their own purposes. This study highlights a bidirectional relationship between the “baggage” that members bring with them and the everyday practice developed over the course of the LC’s two-year history. Additionally, the insights gained from this exploration of the LC CoP have practical implications for SALC staff aiming to cultivate and support student-led learning communities.

Published: December 2020

La construcción de conocimiento en las Ciencias Sociales, posee sin duda alguna, un carácter inacabado dada su provisoriedad; pues queda claro que existe siempre algo radicalmente incompleto en este tipo de conocimiento, cuyo estudio se halla precisamente orientado al análisis de los fenómenos sociales. Arribamos a esta afirmación, en virtud de que los fenómenos sociales en general, tienden a asemejarse a periodicidades irrepetibles no sólo por sus actores que en ella interactúan, sino básicamente por la delimitación del tiempo-espacio; sumados al hecho de que son inestables, complejas, dinámicas y contradictorias, que dificultan aún más, las posibilidades de su aprehensión e interpretación.

DIDACTIQUE PROFESSIONNELLE (DIDAPROF): REPERCUSSÃO PARA A PESQUISA EM TORNO DA ATIVIDADE DO PROFESSOR DE MATEMÁTICA
Authors: Alves Francisco Regis Vieira
Published: December 2020

A Didática Profissional (DP) se originou dos estudos desenvolvidos na França, no inicio dos anos 90, com forte teor de interesse endereçado para os processos de aprendizagem e formação de adultos, circunstanciados pelo ambiente de atividades profissionais. Por outro lado, registramos algumas décadas de tradição de estudos desenvolvidos no Brasil, balizados pelos pressupostos da Didática da Matemática (DM). Com origem nesses dois aportes teóricos clássicos, o presente trabalho apresenta uma inédita proposta teórica de complementaridade, objetivando o uso para investigação, com interesse na atividade e aquisição da competência profissional do professor de Matemática. Um elemento que se sobressai dessa proposta se revela pela interpretação cognitivista dos fenômenos originados da significação das atividades especializadas e do prório processo de aprendizagem do trabalhador (do professor de Matemática). Por conseguinte, o trabalho aponta, de forma clara, um fio condutor significante para o desenvolvimento de ulteriores investigações no Brasil, balizadas tanto pela (DP) e pela (DM), objetivando a concepção de uma Engenharia de Formação e a pesquisa em torno da atividade do professor.Palavras-chave: Didática Profissional, Didática da Matemática, Competência profissional, Trabalho do professor.PROFESSIONAL DIDACTICS (DIDAPROF): REPERCUSSION FOR THE RESEARCH AROUND THE ACTIVITY OF THE TEACHER OF MATHEMATICSAbstractThe Professional Didactics (DP) originated from the studies developed in France in the early 1990s, with a strong content of interest addressed to the processes of adult learning and training, circumstantiated by the environment of professional activities.

Based on these two classic theoretical contributions, the present work presents an unprecedented theoretical proposal of complementarity, aiming the use for research, with interest in the activity and acquisition of the professional competence of the Mathematics teacher. An element that stands out from this proposal is revealed by the cognitivist interpretation of the phenomena originated from the meaning of specialized activities and the worker's early learning process (from the Mathematics teacher).

Nossa Senhora do Desterro de Lisboa: depois de convento e hospital, que futuro?
Authors: Moura Soares Clara , Neto Maria João , Mehnert Pascoal Ana , Alves da Cunha João
Published: December 2020

O Hospital do Desterro, situado na Colina de Santana, em Lisboa, foi desativado em 2007, depois de ter sido um hospital de referência no domínio das doenças venéreas e da dermatologia durante mais de 150 anos.

O edifício, concebido como mosteiro da ordem de Cister, em finais do século XVI, transporta consigo vários séculos de história, mas cuja coerência arquitetónica, as suas múltiplas utilizações tenderam a diluir.

Alvo de um recente projeto de reutilização multifuncional de habitação, turismo, lazer e saúde, depois de largas décadas de discussão sobre a inadequabilidade das instalações para uso hospitalar, o debate voltou-se para a salvaguarda do edifício, com novas funções, e para a defesa dos seus valores históricos e patrimoniais.

O presente estudo procura trazer novos dados históricos e novas leituras sobre o edifício do antigo Real Mosteiro de Nossa Senhora do Desterro, em particular para as duas últimas centúrias, enquanto as obras se mantêm suspensas e o seu futuro em aberto.

The aim of this study was to add more information in the field of knowledge regarding the skin structures of a local black goat. topographical, histological and morphometrical studies were carried out in twelve certain different areas of the skin using twenty healthy adult male goats in the autumn season. Hematoxylin and Eosin stain and Masson's Trichrome stain were used for all samples. Results; that the sebaceous glands are composed of clusters of pale staining epithelial cells that located within the dermis and accompanied all primary and some of the secondary follicles. depending on skin area, the sebaceous glands were large in the skin of muzzle, scrotum, abdomen, the medial surface of the limbs and the abdominal surface of the ear. while their sizes are decreased in the skin of tail, lateral surfaces of limbs and dorsal aspect of ear skin. The size of sebaceous glands were inversely proportional to the hair density. The sweat glands except in the skin tail were apical secretion type, while their levels within the beneath of dermis and their density were varied according to the skin area. the skin of muzzle, tail, dorsal surface of the ear had high glandular density followed by the skin of cranial and middle back in addition to lateral surfaces of limbs. Less glandular density was found in the abdominal surface of ear, abdomen, medial surfaces of limbs and scrotum. In addition to the apocrine sweat glands, serous tubular acinus compound glands in the muzzle skin which extended widely beneath of dermis to subdermal layer. these glands were entirely serious excretion units with the main excretory channel that opens directly on the surface of the skin and had no relation with hair follicles.

RF MARKER SIMULATION MODEL FOR INTERVENTIONAL MRI APPLICATIONS

Compared to the other imaging modalities Magnetic Resonance Imaging (MRI) system has many advantages. There is a great demand to carry out interventional cardiovascular procedures under MRI scanner. However, the lack of visible markers and MRI compatible interventional instruments and devices, is the main problem for realizing clinical applications with MRI guidance. In order to provide widespread usage of MRI for endovascular operations, commercial catheters and guidewires must be manufactured by considering many performance criteria including visualization, miniaturization, flexibility and safety.

In this study, an orientation independent simulation model was developed and validated to obtain a reliable method for evaluating the designed RF marker structures in a MRI environment. Utilized RF coil designs have similar size and properties with former constructed clinical grade MRI compatible RF markers in experimental works [1]. Finite Element Method (FEM) simulations were carried out for different RF coil designs to make the computational analysis of their electrical and magnetic characteristics by using COMSOL Multiphysics program.

By delineating an approved simulation platform of a MRI environment, various different designs of RF marker prototypes can be compared between each other in many aspects, instead of realizing these models. Proposed simulation platform enables a convenient facility to determine various parameters of micro coils that have significant effects on visibility and safety performance of the candidate designs including signal to noise ratio (SNR) and Quality (Q) factor, RF induced heating and specific absorption rate (SAR).
Nişanlılar Romanında Salgının Tarihi Gerçekliği ve Kurguya Yansıyan Dehşeti
Authors: OLPAK KOÇ Canan
Published: December 2020

Hastalık, destan dönemlerinden bu yana edebiyatın yararlandığı başlıca izlekler arasındadır. Bireysel trajedileri yaratan tekil hastalıklar kadar toplumun genelini etkilemiş salgın hastalıklar da hem sözlü hem yazılı edebiyata ait metinleri etkilemiştir. Kişilerin tek tek yakalandığı hastalıklar, ikincil kurgu karakterin edebi sahneye çıkmasının ön hazırlığını sağlaması yanında, hastaya karşı bireysel yabancılaşmayı ve zamanla bu durumun metafora dönüşmesi gibi farklı imkânlarda değerlendirilmiştir. Salgın hastalıksa toplumun genelini etkilemesi yönüyle toplum ve birey açısından kabullenme noktasında tekil hastalıklardan ayrılarak topyekûn bir mücadeleye dönüşmüştür. Salgın hastalıkları anlatan edebi eserler, yazarın da bizzat hastalığın mağduru durumunda olduğu örnekler ve geçmişin bir salgın hastalığını kurguya taşıyan eserler olmak üzere farklılıklar gösterir. Marzoni’nin Nişanlılar romanı, geçmişte yaşanmış gerçek bir salgını resmi kaynaklardan yola çıkarak kurguya dönüştürmesi yönüyle dikkat çeken bir romandır. Manzoni, yararlandığı kaynakları doğrudan göstererek 1628-1630 yılları arasında İspanyol egemenliği altındaki Lombardia bölgesinde yaşanan veba salgınını gerçekçi bir yaklaşımla anlatmıştır. Bu çalışmada, Avrupa’da ortaya çıkan salgının İtalya’yı etkileyen yönleri Nişanlılar romanında, salgının önüne geçilemez bir hastalık olarak insanları, şehri ne yönlerden etkilediğinin belirlenmesi amaçlanmıştır. Yerel yönetimlerin salgına karşı tepkileri, bunun halka yansıyan yönleri, din adamlarının şehrin manevi önderleri olarak salgın zamanındaki rolleri ve salgının bütün bu çıkarımların ışığında toplum üzerindeki sarsıntıları ana hatlarıyla ortaya konulmaya çalışılacaktır.
BIBLIOMETRIC ANALYSIS OF FOREIGN DIRECT INVESTMENT AND ECONOMIC GROWTH RELATIONSHIP. A RESEARCH AGENDA
Authors: Cicea Claudiu , Marinescu Corina
Published: December 2020

The relationship between foreign direct investment and economic growth is a relationship that has long been studied in the economic literature, of particular importance for the economic and social development of any nation. The main objective of this paper is to analyze the scientific output in this scientific area, based on a bibliometric analysis, in order to identify some trends and to explain some phenomena within the economic reality. The paper analyzed 2281 documents from the Scopus database, using tools provided by the aforementioned database, VOSViewer and Citespace software. The analysis was carried out on several levels: typology of information dissemination, thematic area of publications, temporal/geographical distribution of documents and their scientific content. Among the findings authors can mention that the connection between foreign direct investment and economic growth is very strong (according to the cluster analysis in VOSViewer); consequently, the focus of the authors migrated from general economic aspects of the relationship to the elements of ecology and environmental protection. Going deeper with the analysis, conducting two parallel analysis of the papers with highest citation burst and keywords with highest citation strength values, some interesting trends were found in the relationship between foreign direct investment and economic growth.
Superorbital Modulation in the High-mass X-Ray Binary 4U 1538–52 and Possible Modulation in IGR J16393–4643
Authors: Corbet Robin H. D. , Coley Joel B. , Krimm Hans A. , Pottschmidt Katja , Roche Paul
Published: December 2020

Hard X-ray observations with the Neil Gehrels Swift Observatory Burst Alert Telescope (BAT) reveal superorbital modulation in the wind-accreting supergiant high-mass X-ray binary (HMXB) 4U 1538−52 at a period of 14.9130 ± 0.0026 days that is consistent with four times the 3.73 day orbital period. These periods agree with a previously suggested correlation between superorbital and orbital periods in similar HMXBs. During the ∼14 yr of observations the superorbital modulation changes amplitude, and since ∼MJD 57,650 it was no longer detected in the power spectrum, although a peak near the second harmonic of this was present for some time. Measurements of the spin period of the neutron star in the system with the Fermi Gamma-ray Burst Monitor show a long-term spin-down trend, which halted toward the end of the light curve, suggesting a connection between

and superorbital modulation, as proposed for 2S 0114+650. However, an earlier torque reversal from INTEGRAL observations was not associated with superorbital modulation changes. B- and V-band photometry from the Las Cumbres Observatory reveals orbital ellipsoidal photometric variability, but no superorbital optical modulation. However the photometry was obtained when the 14.9130 day period was no longer detected in the BAT power spectrum. We revisit possible superorbital modulation in BAT observations of IGR J16393−4643 but cannot conclusively determine whether this is present, although it is not persistent. We consider superorbital modulation mechanisms, and suggest that the corotating interaction region model, with small deviations from orbital synchronization, appears promising.

Ultraluminous quasars (M
1450 ≤ −29) provide us with a rare view into the nature of the most massive and most rapidly accreting supermassive black holes (SMBHs). Following the discovery of two of these extreme sources, J0341+1720 (M
1450 = −29.56, z = 3.71) and J2125−1719 (M
1450 = −29.39, z = 3.90), in the Extremely Luminous Quasar Survey (ELQS) and its extension to the Pan-STARRS 1 footprint (PS-ELQS), we herein present an analysis of their rest-frame UV to optical spectroscopy. Both quasars harbor very massive SMBHs with

). NOEMA 3 millimeter observations of J0341+1720 reveal a highly star-forming (SFR ≈ 1500 M
⊙ yr−1), ultraluminous infrared galaxy (L
IR ≈ 1.0 × 1013
L
⊙) host, which, based on an estimate of its dynamical mass, is only ∼30 times more massive than the SMBH it harbors at its center. As examples of luminous super-Eddington accretion, these two quasars provide support for theories that explain the existence of billion solar mass SMBHs ∼700 million years after the Big Bang by moderate super-Eddington growth from standard SMBH seeds.

Безбедноста на житата и житните производи е од големо нутритивно и токсиколошко значење, бидејќи житната индустрија и нејзините производи имаат голема економска и социјална важност на светско ниво. Во ова пилот истражување е испитана концентрацијата на токсичните елементи во траги арсен, кадмиум и олово, во три мостри од различни производители на ориз: 11,67+5,69mg/kg, 25,67+6,43mg/kg, 47,67+18,01mg/kg, пченично брашно: 7+5mg/kg, 9+1,73mg/kg, 69,92+16,92mg/kg за As, Cd и Pb, соодветно, и производи од брашно (леб: 9,33+2,08mg/kg, 6,67+0,58mg/kg, 36+3,6mg/kg, тестенини: 1,61+1,15mg/kg, 2,67+2,08mg/kg, 30+7mg/kg и чајни колачи: 4,67+4,04mg/kg, 1,33+0,58mg/kg, 53+9,64mg/kg за As, Cd и Pb, соодветно) од македонскиот пазар, со употреба на хидридно генерирачка и електротермичка атомска апсорпциона спектрометрија со мокра дигестија. Извршена е пресметка на учеството во просечниот дневен внес за токсични елементи внесени преку дневна консумација на жито и производи од жито (20% од целодневниот оброк). Придонесот на As (9,86%), Cd (10,02%) и Pb (11,39 %) спореден со просечниот дневен внес и прифатливиот толериран дневен внес, PTDI, беше низок, што покажува дека овие производи се безбедни за употреба во однос на испитаните токсични елементи. Нивоата на токсичните елементи во мострите на македонскиот ориз, пченично брашно и производи од брашно се споредливи со резултатите добиени од различни делови од светот и нивниот внес не претставува здравствен ризик за потрошувачите.

L’exercice d’apprentissage en travail social est un acte délicat, tant pour les formateurs que pour l’apprenant. Les différentes parties entrent dans un processus de partage d’expériences, de savoirs et de questionnements. Ils doivent s’accorder pour se comprendre. Dans un contexte international, lorsque les repères sociaux ou culturels sont différents, les protagonistes vont avoir l’occasion de remettre en question leur compréhension de l’autre en s’apercevant que la lecture utilisée jusque-là ne s’avère pas toujours être en totale adéquation avec la situation vécue. Dans cet article le témoignage d’une étudiante en stage international de travail social nous montre comment son expérience de stage et notamment sa communication avec l’équipe a pu être analysée et regardée « autrement » suite à un processus de supervision.
Correlation of Pulmonary Function to Novel Radiographic Parameters of Collapsing Parasol Deformity in Spinal Muscular Atrophy
Authors: Johnson Mitchell A. , Galagedera Nirupa , Ho Susanne , Hilmara Didja , Campbell Robert M. , Anari Jason B. , Mayer Oscar H. , Cahill Patrick J.
Published: December 2020

Spinal muscular atrophy (SMA) is a neuromuscular disease with manifestations of scoliosis, pulmonary function decline, and, uniquely, collapse of the ribs. Methods to quantify rib deformity and its impact on pulmonary function are sparse. The authors propose new radiographic measurements to quantify the aspect of SMA known as collapsing parasol deformity and correlate these measurements with pulmonary function. Twenty-eight full-spine radiographs of pediatric SMA patients were measured twice by 3 independent investigators, with 2 weeks separating each measurement. Radiographic measurements, demographics, spirometry results, and assisted ventilation rating were obtained. Twenty-one patients with spirometry metrics were assessed to correlate pulmonary function and spinal measurements. The intrarater intraclass correlation coefficient (ICC) for the measurements ranged from 0.706 to 0.99, and the interrater ICC ranged from 0.64 to 0.97. Eighteen of 19 variables had ICC values greater than 0.75 for inter- and intrarater reliability. Twenty-one patients with forced expiratory volume in 1 second and forced vital capacity were assessed in terms of these measurements. Ratio of the concave hemithoracic width at T6/convex hemithoracic width at T6 (
P
=.004) and ratio of convex vertical rib displacement at the apical rib/concave vertical rib displacement (
P
=.021) were both significantly correlated with decreased pulmonary function. No significant correlation was found examining the average vertical rib displacement at the apical rib. High inter-and intrarater reliability can be obtained in a variety of spinal measurements of SMA patients. Various measurements are correlated to diminished pulmonary function, specifically variables showing asymmetric changes in the chest cavity. [

At present, the need for an ultra-high speed and efficient communication through mobile and wireless devices is gaining significant popularity. The users are expecting their network to offer real-time streaming without much latency. In turn, this will result in a considerable rise in network bandwidth utilization. The live streaming has to reach the end users mobile devices after traveling through the base station nodes, core network, routers, switches, and other equipment. Further, this will lead to a scenario of content latency and thereby causing the rejection of the mobile devices users' request due to congestion of the network and mobile service providers' core network witnessing an extreme load. In order to overcome such problems in the contemporary 5G mobile networks, an architectural framework is essential, which offers instantaneous, ultra-low latency, high-bandwidth access to applications that are available at the network edge and also making the task processing in close proximity with the mobile device user.

Previous research demonstrates that actors seek acceptance of innovations during the diffusion and adoption process, but exactly what kind of acceptance they seek and how they go about obtaining this remains unclear. This study interrogated academic databases and Twitter to identify and analyze research and grey literature concerning blockchain adoption in human resources (HR). The data was analyzed through the theoretical lens of pragmatic, moral, and cognitive legitimacy to explore how potential adopters of this innovation conceive its value and alignment with their goals. The results show how pragmatic considerations are emphasized around streamlining current HR processes. Arguments for moral legitimacy are considered far less, while narratives on cognitive legitimacy are absent. The findings also show high levels of conformity around legitimation strategies within the community, with only some evidence of selection and manipulation strategies. The authors discuss the implications of these findings for the adoption and diffusion of blockchain in the HR sector.

The main objective of this chapter is to take a deeper look into the infrastructural condition of the hospitals across the districts of West Bengal, India. There is a liaison between various variables and the infrastructural growth of the public healthcare centres. In this chapter, the authors have formed a panel data from the year 2004 – 2017, consisting of 17 districts across West Bengal. They have assessed the random effect model on the data to choose their respective hypothesis. A Bayesian risk analysis had also been carried out on the mortality rate of the patients on which factors it depends. Next, a Poisson distribution model is being fit to get some insights into the data. Afterward, they predicted the number of patients who will arrive in 2020 and the shortfall of hospitals is also being projected. The remedies to these have also been suggested in that section. At last, they carried out an econometric analysis in the healthcare domain and took a closer look at how healthcare expenditure affects our focus variables performance.

Published: December 2020

In recent years, laptops and smart phones have become unavoidable, and the restriction in usage of these devices is impracticable. Starting from children to aged persons, many people spend their waiting time, travel time in this nicely, but the issue arises due to their influence in the golden working hours. It leads to waste of time, energy, and some of these practices may lead to addiction. Hence, a techno-cognitive approach of the biomedical analysis of brain can be done through electroencephalography (EEG) and functional magnetic resonance imaging (fMRI). After investigations, a strategy is to be implemented to explore the dynamics of therapy on reducing the addiction. But it is not a simple task of making the addicted persons practice yoga or meditation routinely. It can be made possible through gamification of these practices. This chapter focuses the pre and post recording of the addicted person's brain activity to analyze and measure the improvement after the treatment via gamification strategy. After certain duration, the outcome is addiction removal.
Documenting Student Representation of Indigenous HIV/AIDS Information and Integration Into the School Curriculum
Authors: Sekiwu Denis , Rugambwa Nina Olivia
Published: December 2020

Often times, contemporary health and epidemiological practices ignore indigenous information on HIV prevention. Colonial hegemony tends to replicate indigenous knowledge bases as primordial, superstitious, and lacking vivid scientific explanation to qualify the test for medical diagnostic study. Using an information science viewpoint and an anti-colonial discursive theory, this paper challenges the skewed discernment that it is only Western knowledge production that is considered legitimate knowledge. The authors argue that indigenous HIV/AIDS information exists and can be integrated into the curriculum to complement Western knowledge paradigms on adolescent HIV prevention.

Influenza outbreaks are associated with significant morbidity. Our aim was to determine the factors associated with increased mortality in hospitalized patients admitted with diagnosis of influenza, at a tertiary care center in Pakistan. This study included all adult patients with an influenza infection, confirmed by realtime reverse-transcriptase polymerase-chain-reaction (RT-PCR) at Aga Khan University Hospital Pakistan. In our study, 112 patients with laboratory-confirmed influenza virus infection were admittedat our hospital from the 1st of January 2013 to the 31st of December 2018. Eighty-nine patients (79.46%) were managed in ward or special care units and 23 patients (20.5%) received treatment in intensive care unit (ICU). The overall mortality in our study was 15/112 (13.4%) with the mortality rate of ICU patients being 47.8% while the mortality rate of patients treated in special care units and wards was only 4.5%. The mean age of patients with influenza infection was 58.1 years (±16.6). Influenza virus type A was found in 87 patients (77.6%), while influenza type B was present in only 25 (22.4%) patients. Out of the 15 non-survivors, 14 had influenza A. Only 17 patients (15.2%) were found to have positive culture of respiratory specimen, out of which 3 were non-survivors and 14 were survivors. Our analysis identified septic shock (odds ratio 45.24; 95%, confidence interval 6.20-330; p<0.001), renal failure (odds ratio 10.88; 95%, confidence interval 1.61-73.52; p=0.01) and ICU stay (odds ratio 17.22; 95%, confidence interval 2.68-110.5; p=0.003) as independent risk factors associated with in-hospital mortality.

Authors: Gok Duygu Kurt , Ünal İlker , Aslan Kezban
Published: December 2020

Aims:

This study aims to determine the sleep quality of night-shift workers, determine the prevalence and characteristics of sleep disorders related to shift work, and compare sleep characteristics between shift workers and day workers.

Subjects and Methods:

The study included 1473 individuals employed in three different areas (health, security, and labor) as shift (78.5%) or day (21.5%) workers in the city of Adana, Turkey. Data were collected using a structured questionnaire consisting of 132 questions. The questionnaire included demographic data, education level, socioeconomic status, shift schedule, accompanying health problems, sleep disorders and sleeping habits, the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index, the Berlin Questionnaire, and the Restless Legs Syndrome (RLS) scale.

Statistical Analysis Used:

The SPSS for Windows 20.00 software package was used for statistical analyses.

Results:

Day workers and shift workers exhibited excessive daytime sleepiness in 17.1% and 24.9% (P = 0.004), poor sleep quality in 41.5% and 44.3% (P = 0.374), chronic insomnia in 8% and 16.2% (P < 0.001), RLS in 4.7% and 5.3% (P = 0.818), and sleep-disordered breathing in 7.3% and 7% (P = 0.864), respectively.

Conclusions:

Shift work significantly compromises sleep quality. In particular, fixed night shifts or rotating shift workers experience relatively higher rates of decline in subjective sleep quality, excessive daytime sleepiness, and chronic insomnia compared with day workers.
