Abstract
Despite its high accuracy to detect the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the reverse transcription-quantitative polymerase chain reaction (RT-qPCR) approach possesses several limitations (e.g., the lengthy invasive procedure, the reagent availability, and the requirement of specialized laboratory, equipment, and trained staffs). We developed and employed a low-cost, noninvasive method to rapidly sniff out the coronavirus disease 2019 (COVID-19) based on a portable electronic nose (GeNose C19) integrating metal oxide semiconductor gas sensor array, optimized feature extraction, and machine learning models. This approach was evaluated in profiling tests involving a total number of 615 breath samples (i.e., 333 positive and 282 negative COVID-19 confirmed by RT-qPCR) obtained from 83 patients in two hospitals located in the Special Region of Yogyakarta, Indonesia. Four different machine learning algorithms (i.e., linear discriminant analysis (LDA), support vector machine (SVM), stacked multilayer perceptron (MLP), and deep neural network (DNN)) were utilized to identify the top-performing pattern recognition methods and to obtain high system detection accuracy (88–95%), sensitivity (86–94%), specificity (88–95%) levels from the testing datasets. Our results suggest that GeNose C19 can be considered a highly potential breathalyzer for fast COVID-19 screening.

Abstract
This paper presents the experimental and analytical studies to investigate the impact of concentrated laminated bamboo butt-joints on the flexural properties of vertically laminated bamboo-timber hybrid beams (VLHBs, or flitch beam). The experimental results reveal that the concentrated butt-joints significantly reduce the flexural strength of the VLHB. They also suggest that the failure mechanism of the VLHBs with or without concentrated butt-joints are completely different. In addition, laminated bamboo lumber with concentrated butt-joints was found to be unsuitable for structural applications. The analytical estimations show close agreement with the experimental results. However, due to the layout of the sample VLHB, the experimental study cannot confirm the impact of the butt-joints on the modulus of elasticity in bending.
Electricity, Computing Hardware, and Internet Infrastructures in Health Facilities in Sierra Leone: Field Mapping Study

Published: July 2021

Background
Years of health information system investment in many countries have facilitated service delivery, surveillance, reporting, and monitoring. Electricity, computing hardware, and internet networks are vital for health facility–based information systems. Availability of these infrastructures at health facilities is crucial for achieving national digital health visions.

Objective
The aim of this study was to gain insight into the state of computing hardware, electricity, and connectivity infrastructure at health facilities in Sierra Leone using a representative sample.

Methods
Stratified sampling of 72 (out of 1284) health facilities distributed in all districts of Sierra Leone was performed, factoring in the rural-urban divide, digital health activity, health facility type, and health facility ownership. Enumerators visited each health facility over a 2-week period.

Results
Among the 72 surveyed health facilities, 59 (82%) do not have institutionally provided internet. Among the 15 Maternal and Child Health Posts, as a type of primary health care unit (PHU), 9 (60%) use solar energy as their only electricity source and the other 6 (40%) have no electricity source. Similarly, among the 13 hospitals, 5 (38%) use a generator as a primary electricity source. All hospitals have at least one functional computer, although only 7 of the 13 hospitals have four or more functional computers. Similarly, only 2 of the 59 (3%) PHUs have one computer each, and 37 (63%) of the PHUs have one tablet device each. We consider this health care computing infrastructure mapping to be representative with a 95% confidence level within an 11% margin of error. Two-thirds of the PHUs have only alternate solar electricity, only 10 of the 72 surveyed health facilities have functional official internet, and most use suboptimal computing hardware. Overall, 43% of the surveyed health facilities believe that inadequate electricity is the biggest threat to digitization. Similarly, 16 (22%) of the 72 respondents stated that device theft is a primary hindrance to digitization.

Conclusions
Electricity provision for off-electricity-grid health facilities using alternative and renewable energy sources is emerging. The current trend where GSM (Global System for Mobile Communication) service providers provide the internet to all health facilities may change to other promising alternatives. This study provides evidence of the critical infrastructure gaps in health facilities in Sierra Leone.

Published: July 2021

Background. The problem of the quality of life (QoL) is relevant nowadays, especially for patients with chronic diseases, including juvenile idiopathic arthritis (JIA) and the subtype of JIA associated with uveitis (JIA-u). The purpose was to carry out a literature review on the QoL in children with JIA and JIA-u, with an analysis of existing tools, the possibility of their use in children, and to assess the QoL indicators of children with JIA, who were treated in a specialized department of the hospital. Materials and methods. The search was performed in the PubMed, Medline, and Google databases using the keywords: JIA, rheumatoid arthritis, uveitis, JIA-u, arthritis with uveitis, QoL, QoL in children. Inclusion criteria were as follows: publication after 2010, use of questionnaires to assess QoL, the sample of patients over 30 people. The type of instrument for assessing QoL, the sample nature, and the QoL indicators of patients were analyzed. The study was carried out at the premises of the State Institution “Institute for Children and Adolescents Health Care of the National Academy of Medical Sciences of Ukraine” and involved 41 children with JIA (22 with polyarticular, and 19 with oligoarticular variants): 25 girls and 16 boys aged 3–17 years with disease duration of 40.2 ± 6.2 months. Thirty-six of them received methotrexate, and 5 — sulfasalazine. The disease activity was assessed by the Juvenile Arthritis Disease Activity Score (JADAS27) and the functional state — by the Childhood Health Assessment Questionnaire (CHAQ). For quality of life assessment, the Pediatric Quality of Life InventoryTM validated for Ukraine was used. Results. The analysis included 73 foreign scientific papers from 2011 to 2021, among which 11 are fully devoted to the assessment of QoL in children with JIA, and 62 partially cover this topic in children and adults with arthritis. In Ukraine, these issues are not discussed enough (6 articles on the evaluation of QoL in children), the factors for its deterioration remain unclear. The level of activity according to JADAS27 in children in subgroups with both poly- and oligoarticular variants was high (11.20 ± 7.04 and 8.9 ± 4.2 points), and the functional state (on CHAQ) — 0.19 ± 0.17. In children with JIA, QoL indicators are reduced, especially on the scales of emotional and school functioning, and closely correlate with disease activity (r = 0.784, p < 0.05). Conclusions. The analysis of the conducted studies showed that decreased disease activity is not accompanied by the QoL indicators optimization, which remain reduced. Recently, the situation with the QoL assessment in domestic medicine has been improving, relevant questionnaires are being actively introduced. However, the ambiguity of the results in world medicine and the presence of a small number of works on this topic determine the urgency of the problem of QoL in children with JIA in Ukraine.

Published: July 2021

Background. The problem of gastrointestinal diseases in children remains quite relevant due to the high prevalence and presence of atypical symptoms and comorbidities pathogenetically associated with acid-dependent diseases. The purpose was to study the dynamics of inflammatory changes of the mucous membrane in children with duodenal ulcer (DU). Materials and methods. One hundred and six children aged 10 to 18 years with DU were examined. To verify the diagnosis, all children underwent endoscopy, pH-metry, morphological examination of gastrobiopsy samples, examination for Helicobacter pylori (H.pylori). Results. 49.1 % of children with DU were diagnosed with impaired motor-evacuatory function in the form of duodenogastric and/or gastrooesophageal reflexes, 81.1 % of patients presented with H.pylori was determined. Erythematous changes of the gastric and duodenal mucosa predominated. 92.4 % of patients were diagnosed with chronic non-atrophic gastritis and/or gastroduodenitis with varying degrees of inflammation, 7.6 % of children — chronic atrophic gastritis. There was a decrease in height and signs of desquamation of the superficial epithelium, in 72.3 % — the development of granular dystrophy, in 6.9 % of patients without H.pylori infection and in 57.5 % of H.pylori infected — neutrophilic infiltration of the mucous membrane. In the dynamics after 3 months, the height of the superficial epithelium and the frequency of desquamative changes decreased, and the proliferation of the glandular epithelium 12.4 % increased. Conclusions. Morphological changes in biopsies of the gastric mucosa differ depending on the presence of H.pylori infection and partially persist for 3 months after treatment.

Published: July 2021

The advancement of technologies and the recently forced lockdown by Covid-19 are bringing changes to the organisation of the learning process by accelerating the introduction of e-learning to create a learner-centred technology-based approach to English studies, thus stepping towards digital humanities. These trends initiated the institutional project Mobile and Desktop Software Integration in Bachelor and Master Study Programmes. The present study, using a questionnaire, elicits university students’ attitudes to the mobile applications and speech analysis software-based seminar activities in Moodle e-course in accordance with the blended learning model selected for the studies of theoretical grammar and phonetics. It is a cross-sectional, focused, and exploratory case study, comprising a description of factors, contributing to the problem of blended learning model selection. The yielded data demonstrate that students do not possess extensive prior experience with the use of software and mobile applications to study English grammar and phonetics. After completing seminar tasks, they favourably account for the integrated blended learning materials and consider that those facilitate their learning process.
From Defoe to Coetzee’s Foe/Foe through Authorship
Authors: Suciu Andreia Irina , Culea Mihaela 
Published: July 2021

The article investigates the concept of authorship in the works of two authors separated by three centuries, namely, Daniel Defoe and J. M. Coetzee, both concerned, in different ways, with aspects regarding the origin and originators of literary works or with the act of artistic creation in general. After a brief literature review, the article focuses on Coetzee’s contemporary revisitation of the question of authorship and leaps back and forth in time from Defoe’s Robinson Crusoe (1719) to Coetzee’s Foe (1986). The purpose is that of highlighting the multiple perspectives (and differences) regarding the subject of authorship, including such notions and aspects as: canonicity related to the act of writing and narrating, metafiction, self-reflexivity and intertextuality, silencing and voicing, doubling, bodily substance and the substance of a story, authenticity, (literary) representation and the truth, authoring, the author’s powers, the relation between author and character or between narrator and story, authorial self-consciousness, agency, or ambiguity. The findings presented in the article show that both works are seminal in their attempts to define and redefine the notion of authorship, one (Defoe) concerned with the first literary endeavours of establishing the roles of professional authorship in England, while the other (Coetzee), intervenes in existing literary discussions of the late twentieth century concerning the postmodern author and (the questioning of or liberation of the text from) his powers.

Published: July 2021

The problem statement: based on the analysis of the features of the development of modern public information and telecommunications networks (ITN), which consist in the geographical dispersion of network resources, sources and recipients of information; the pulsating nature of network traffic; heterogeneity of elements and applied network technologies; randomness of functioning; “intolerance” to management; the essential inconsistency of the main char-acteristics and the impossibility of a complete mathematical description, make it impossible to use the existing methods of control of the information and telecommunications system and the need to synthesize its subsystem of intellectual monitoring, as well as to develop new methods based on intelligent approaches. The purpose of the work is to provide synthesis of the subsystem of intelligent monitoring of the information and telecommunications network of the Ministry of Transport of the Russian Federation, as one of the key segments of the situation center of the department being created at the present time. Structuring of the controlled space by the terms “monitoring zone”, “critical element” and “technical condition classes” form the basis of a new approach to intelligent monitoring, regardless of the constant improvement (evolution) and heterogeneity of heterogeneous network infrastructures. The values obtained in the course of parametric synthesis of acceptable optimal values of the degree of loading of channels with measuring information make it possible to calculate the throughput of technological channels of tele-measurement-tele-signaling and the necessary amount of buffer memory with a known network topology and a given gravity matrix, providing the average minimum delivery time of intelligent agents (packets of measuring information) and the value of the maximum probability of failure
in their service within acceptable limits. Based on the proposed hypergraph of the topological relationship of the monitoring zones of ITN of a household, the structure of its monitoring subsystem is constructed at the levels of fragmentation during the aggregation of controlled processes. The obtained results of the structural and parametric synthesis form the basis of the conceptual model of intelligent monitoring of ITN of the department
La heteromaricageneidad contradictoria como herramienta crítica cuy(r) en las literaturas andinas
Authors: Falconí Trávez Diego 
Published: July 2021

Se busca, en primer lugar, dar cuenta de lo cuy(r) como gesto contestatario y de la “mala traducción” de lo queer, que pretende, en la segunda década del siglo xxi, juntar disidencia sexual y anticolonialidad en el contexto andino. El gesto cuy(r) da paso a proponer una mutación que cambia del concepto heterogeneidad contradictoria enhebrado por Antonio Cornejo Polar en el siglo pasado. Este concepto deviene, de entre otros, de heteromaricageneidad contradictoria, para así rescatar el potencial antiuniversalista del teórico peruano, que si bien posibilita validar estéticas y políticas locales, carece de cualquier focalización respecto al género, en específico, a las disidencias sexuales. El artículo analiza brevemente casos de la literatura andina del siglo XX que ejemplifican la heterosodomitageneidad contradictoria para finalizar con conclusiones respecto a las traducciones culturales y semánticas de lo queer en los Andes y el resto del Abya Yala.

Published: July 2021

Co-sleeping merupakan solusi jangka pendek yang efektif terhadap anak dengan kesulitan menginisiasi tidur (sleep onset). Pada sisi lain, co-sleeping berkorelasi dengan kemungkinan lebih tinggi untuk terbangun di malam hari (night waking), durasi tidur yang lebih pendek, penolakan yang lebih tinggi untuk tidur, dan kualitas tidur yang lebih rendah. Intervensi yang paling efektif dalam mengatasi co-sleeping adalah modifikasi perilaku. Penelitian ini bertujuan menguji efektivitas penerapan teknik-teknik modifikasi perilaku yang paling banyak digunakan dalam mengatasi co-sleeping, yaitu; positive routine dan extinction. Selain teknik-teknik tersebut, edukasi orang tua, pemberian feedback, dan reinforcement juga dilakukan dalam program ini. Partisipan penelitian ini adalah seorang anak berusia 5 tahun dengan masalah co-sleeping. Hasil penelitian membuktikan bahwa penerapan teknik-teknik tersebut memiliki efektivitas yang baik untuk menurunkan perilaku co-sleeping pada anak usia dini. Anak berhasil tidur sendiri, juga menunjukkan penurunan durasi sleep onset dan night waking. Terdapat beberapa faktor yang mendukung pelaksanaan intervensi ini; positive routine yang terbangun dengan baik sejak anak masih bayi, anak yang terbiasa melakukan aktivitas fisik secara rutin, gaya pengasuhan orang tua, juga penguasaan anak terhadap teknik relaksasi.
Kata Kunci: modifikasi perilaku, co-sleeping, graduated extinction, positive routine, sleep training

Hidayatul Muslimin 1 Kubu Raya Boarding School and Ma’had Labbaik Pontianak have a problem in term of water quality. The limited quantity as well as the uncertainty of rainwater cause Hidayatul Muslimin 1 Boarding School and Ma’had Labbaik using well to use well to meet the needs of clean water. The physical quality of well water is dark brown in color because of the peat soil around both of locations. Well water is only pumped toward the reservoir without any water treatment process, thereby potentially causing diseases such as itching as well as causing yellow color in clothing and kitchen utensils. Thus, installation of water treatment unit is needed to treat well water into the clean water which is suitable for everyday use. Treatment technology used are chlorination, aeration, and filtration using clamshell media, with a processing capacity of 1000 liters. The method used is the participatory method by involving students in socialization, operation, and maintenance of water treatment installation. The physical quality of water is clean after treatment and suitable for everyday use. Keywords: Aeration, Filtration, Chlorination, Water Treatment
