La relation éducative aux prises avec les prescriptions institutionnelles
Authors: Frigout Stéphanie
Published: September 2021

En 2013, la Loi pour la refondation de l’école de la République institutionnalisait le terme bienveillance. Cet article vient déplier quelques éléments d’analyse d’un entretien clinique à visée de recherche mené auprès d’une professeure des écoles novice. La consigne ouverte l’amenait à évoquer les résonances que le terme bienveillance rencontrait dans sa pratique de classe. L’insistance de l’étudiante sur sa volonté de conserver une « position neutre » inconditionnelle questionne l’interprétation singulière de la prescription et les compromis défensifs associés, notamment le clivage opéré dans le discours entre attitude bienveillante et revendication d’une neutralité excessive.
Management of urban air logistics with unmanned aerial vehicles: The case of medicine supply in Aveiro, Portugal
Authors: Silva Mário , Silva Jorge
Published: September 2021

Purpose: This research aims to investigate the relation between urban logistics and all delivery systems used. The unmanned aerial vehicle (UAV) and the unmanned aerial system (UAS) have been under investigation in the world of logistics, having been pointed as the next logistic technology. For that reason, this article proposes the use of UAV in urban logistics.Design/methodology/approach: We set for the methodology study the current state of this system and analyze what lies ahead soon. Based on this information, we intend to implement a scenario of deliveries in an urban environment. This scenario will be in the city of Aveiro and consists of the delivery of medicines into pharmacies located in an urban environment. With this study, we pretend to find the best current and future solution to operate in an urban environment, with the conventional vehicle or the UAV/UAS.Findings: The legal implications for the use of UAV/UAS are one important factor that can set back the use of these technologies due to the lack of legislation. Although this technology has some limitations in endurance and payload, this investigation reached a consensus in the use of UAV for logistics in urban areas, in small payloads (around 15 kg), and low endurance (around 25 min). The UAV/UAS brings excellent advantages that the conventional vehicle cannot overcome: direct routes; traffic congestion; and environmental legislation.Practical implications: This study brings an overview of a possible scenario for urban logistics. Although this is currently not possible, soon, this scenario could be implemented. This would bring a reduction in operation costs and reduce the congestion in the urban cores of the cities.Originality/value: Based on this research, this delivery system could, in the future, help and be the starting point for UAV/UAS logistics, specifically in the delivery of medicines.

Published: September 2021

Background

Indonesian school children spend one-third of their time in school, where they are exposed to a variety of foods at school canteens. However, the healthiness of school canteens is not yet well understood. This study was conducted to characterize the healthiness and quality of management of school canteens, and measure readiness of school canteens to reopen following COVID-19 closures.

Design and methods

Mixed methods were used to conduct a cross-sectional study. Data were collected from schools located in the Bantul District of Indonesia. Primary schools (n=152) were randomly selected, with a final sample size of 147. Data were collected using Google Forms, delivered via WhatsApp or e-mail. School canteens were classified as healthy if they had a Healthy Canteen Score (HCS) ≥10, or unhealthy if they had a HCS<10.

Results

Less than half (43.5%) of school canteens were deemed to be healthy. School canteens were more likely to be healthy if the canteen manager had a formal decision letter (OR=15.2; 95% CI=3.7-62.5); used print material messaging (OR=3.2 to 4.6 times); or received inspection by external officers periodically (OR=2.8; 95% CI=1.04-7.5). Readiness to reopen was 4.5 (OR=4.5; 95%CI: 1.1-17.9) times higher among schools that had their own canteen, and 4 (OR=3.9; 95% CI=1.1-13.8) times higher among schools located in rural areas, adjusting for the remaining variables.

Conclusions

School canteen healthiness can be improved by implementing national food policy and healthy school canteen standards accompanied by the existence of good management practices within schools, particularly following the COVID-19 pandemic.
Comparison of Gabbet's staining, Ziehl–Neelsen staining with fluorescent microscopy for diagnosis of pulmonary tuberculosis
Authors: Sharma Sharmila , Nagmoti Jyoti M.
Published: September 2021

Background:

Sputum staining for acid-fast bacilli and microscopic examination methods are more sensitive and specific, less time consuming, low cost than other methods for the diagnosis of pulmonary tuberculosis (TB).

Methods:

In this cross-sectional study conducted over 1-year (n = 109), the sensitivity, specificity and cost-effectiveness of Gabbet's staining, Ziehl–Neelsen (Z-N) staining for the diagnosis of pulmonary TB were studied considering with fluorescence staining method as the gold standard.

Results:

Majority of the patients belonged to the age group between 21 and 40 years (45.5%). With fluorescence staining, it was found that 25 of the 44 positive smears were of good quality, 12 were of average quality and 7 had poor quality. With Z-N staining, 9/29 of the positive smears were of good quality, 10 were of average quality and poor quality each. With Gabbet's staining, 12 of the 33 positive smears were of good quality, 14 were of average quality and 7 were of poor quality. The sensitivity of the Gabbet's staining (75%) was found to be greater than the Z-N staining (65.9%) considering fluorescence staining as the gold standard.

Conclusions:

Gabbet's staining can be used as an effective alternative to Z-N staining in low resource settings.
Study of quality of sputum being submitted for smear examination
Authors: Regati Maneesha , Srikanth E. , Gowrinath Karanam
Published: September 2021

Background:

One of the key factors influencing the results of sputum smear microscopy is the quality of sputum being submitted.

Methods:

This is a prospective study of quality of sputum specimens being submitted for smear examination under Revised National Tuberculosis Control Programme and its impact on diagnostic yield of sputum smear microscopy. Based on sputum Gram's staining results, the submitted specimen was classified as 'sputum' and 'saliva'.

Results:

During the period 21 April to 20 June 2012, 238 sputum specimens submitted for evaluation were studied. Of these, 196 (82%) specimens were submitted for diagnosis and 42 (18%) specimens were obtained during follow-up evaluation. Overall, 42/238 (17.6%) specimens were in fact 'saliva' and not sputum. Among specimens submitted for diagnosis (n = 196), 28/167 (16.8%) specimens reported as 'sputum acid-fast bacilli (AFB) negative' were in fact saliva. Among the specimens submitted on follow-up examination (n = 42), 14 of the 38 (36.8%) specimens reported as 'sputum AFB negative' were actually saliva. A significantly higher proportion of sputum smears submitted on follow-up examination were actually 'saliva' as compared to specimens submitted for diagnosis (14/42 [33.3%] vs. 28/196 [14.3%], χ
2 = 6.738; P = 0.014). None of the saliva samples were reported to be 'sputum positive'.

Conclusions:

The fact that a significant proportion of specimens that are reported smear negative are in fact saliva and not sputum highlights the importance of sputum quality in smear microscopy results. Follow-up specimens are more likely to be saliva possibly because directly observed therapy (DOTS) treatment would have resulted in clinical improvements and patients may not be producing significant sputum anymore.

Ethnobotanical survey of medicinal plants remains a veritable source of information leading to discovery of new lead compounds of pharmaceutical importance thus, the need for continual search for medicinal plants via ethnobotanical surveys in Nigeria. Structured questionnaires were administered amongst traditional healers. A few other anecdotal claims about efficacy of herbs from people who at one time or the other have used the plants for wound healing were also sampled. The result of an ethnobotanical survey of plants used in the treatment of wound in Ijebu North Local Government area of Ogun State and Ibadan North Local Government area of Oyo state of Nigeria are reported. A total of 71 species of plants covering 43 families were identified; representing 51 recipes. Carica papaya Linn, Elaeis guineensis Jacq, Chromolaena odorata Meull. Arg, Gladiolus psittacinus Hook.f., Vetivera kotschyana (Benth.) Stapf, Securidaca longipedunculata Fresen and Euphorbia laterifolia Linn were prominent among the recipes. Among all the families identified in the recipes, Euphorbiaceae was most mentioned (7.0%) followed by Compositeae, Fabacceae, Malvaceae and Meliaceae families (4.0%), Amaryllidaceae, Annonaceae, Arecaceae, Asphodeloideae, Asteraceae, Cucurbitaceae, Leguminosae, Musaceae, Poaceae, Rubiaceae, Rutaceae, Solanaceae, Sterculiaceae, Zingiberaceae followed closely (3.0%) while Acanthaceae, Amaranthaceae, Anacardiaceae and others had 1.0%. Out of the recipes, 51.9% are either leaves only or in combination with other parts, while 21.5% are stem bark, 7.6% are seeds and 3.8% are roots, bulbs and fruits respectively.

THE DEAD-BOX PROTEIN CSHA FROM Staphylococcus aureus Mu 50 EXHIBITS RIBONUCLEASE ACTIVITY
Authors: DIEU NGUYEN HANH THI , NGUYEN NGOC AN , BUU TRAN GIA , VIET PHAM TAN
Published: September 2021

DEAD-box proteins play important roles in many RNA processes ranging from RNA synthesis to RNA decay. Furthermore, it has been reported that some bacterial DEAD-box proteins known to be components of the RNA degradosome do not cleave RNA substrates directly. However, the role of DEAD-box proteins in RNA degradation is poorly understood. The present study demonstrated that the DEAD-box protein CshA from the vancomycin-resistant Staphylococcus aureus strain Mu50 possesses RNA degradation activity, ribonuclease activity. Despite having RNA-dependent ATPase activity, CshA did not exhibit RNA helicase activity in vitro. Instead, CshA catalyzed the degradation of single-stranded RNAs of various duplex RNA substrates to form blunt-end RNA products. Thus, we suggest that the ribonuclease activity of the DEAD-box protein CshA may contribute to RNA remodeling in the bacterial RNA degradosome. To our knowledge, this study is the first to report that a DEAD-box protein from a pathogenic bacterium is implicated in multiple ATP-independent activity on RNA, such as degradation.

AN APPROACH TO EXTENDING QUERY SENTENCE FOR SEMANTIC ORIENTED SEARCH ON KNOWLEDGE GRAPH
Authors: DUY CÔNG CHIẾN TẠ
Published: September 2021

There are many applications related to semantic web, information retrieval, information extraction, and question answering applying ontologies in recent years. To avoid the conceptual and terminological confusion, an ontology is built as a taxonomy ontology which identifies and distinguishes concepts as well as terminology. It accomplishes this by specifying a set of generic concepts that characterizes the domain as well as their definitions and interrelationships. There are some methods to represent ontologies, such as Resource Description Framework (RDF), Web Ontology Language (OWL), databases etc. depending on the characteristic of data. RDF, OWL usually is used the cases when data structure is objects which the relationship among the objects is simple. But if the relationship among the objects is more complex, using databases for storing ontologies is an approach to be better. However, using relational databases do not sufficiently support the semantic orientated search by Structured Query Language (SQL) and the searching speed is slow. Therefore, this paper introduces an approach to extending query sentences for semantic oriented search on knowledge graph.
Basic Programming Concepts as Explained for Preschoolers
Authors: Betelin V.B. , Kushnirenko A.G. , Leonov A.G. , Mashchenko K.A
Published: September 2021

The development of information technologies has formed a socio-economic request to reduce the age at which children can be introduced to programming. After 6 years’ efforts, the authors managed to develop and on a large scale introduce a one-year programming course for preschoolers, which is built on a metaphor of programmed control. During the course development, a set of basic programming concepts was selected and specified to be mastered by preschoolers aged 6+ in the activity-game form. This set of concepts goes back to Seymour Papert's ideas about teaching programming by writing programs that control moving objects using intuitive sets of commands. The main feature of the proposed system of concepts, allow at the initial stage of training to demonstrate and assimilate all the elements of the concept in the real, not in the virtual world. In the picture of the World, which we explain and demonstrate to children, only one function remains at the computer - the execution of the program it has memorized. Everything else happens in the real world. In the real world, an environment is created in which a real robot will move. In the real world, a program is created from tangible objects, which will then be "shown" to the computer so that it stores it in its memory and can then execute it at the command of a human. In the real world, obeying the signals of the computer, the robot performs the work stipulated by the program. This allows you to begin acquaintance with the programming of children from 4 years old, without working individually or collectively with electronic screens, which in today's Russia is prohibited by federal medical authorities in the educational process of children under 5 years old. The course is built on the text-free pictographic programming system PiktoMir developed by Russian Academy of Sciences. The methodological content of the course allows each preschooler to gain experience in the development and debugging of 120-150 simple programs by the end of the course. The final part of the article discusses the authors' plans for the development of a three-year textless programming course, methodologically and instrumentally connected with the primary school programming course.

A Novel Approach to the Safe and Effective Mobilization of a Super-Obese Patient: A Case Report
Authors: Anaf Jessica , Wigmore Amy , Stiller Kathy
Published: September 2021

Purpose: The incidence of obesity is rising worldwide, as is the presentation of these patients to the acute hospital setting. As a result of their complex nature, including medical co-morbidities, psychosocial issues, and healthcare resource limitations, management of these patients requires a coordinated and intensive multi-disciplinary approach. Although there are considerable data reporting the surgical management of obese patients, there is very limited literature regarding non-surgical interventions, including approaches to safe and effective mobilization. Methods: A case report is presented of a 55-year-old super-obese male transferred to a major tertiary referral healthcare centre for management of his overall medical condition and rehabilitation. As a result of the patient’s inability to tolerate the supine position because of central obesity, a novel approach to mobilization was undertaken whereby a bariatric tilt-table was used to facilitate standing and walking from the semi-prone position. This mobilization program was led by a physiotherapist with support and input from the multi-disciplinary team. Conclusion: It was safely and effectively implemented and enabled the patient to be discharged to his desired rural location.

Published: September 2021

Introduction: The Health Educators Academy at Western Carolina University was developed by the Dean of the College of Health and Human Sciences. Interdisciplinary fellows in the 2015 HEA focused on competency based education (CBE), which naturally incentivizes collaborative, interdisciplinary and interprofessional work. The 2015 Health Educator Academy Fellows researched healthcare competencies and designed curriculum changes that aligned within these parameters. This article discusses the creation of a first-year, interprofessional healthcare course that emphasizes CBE as well as interprofessional practice. Interprofessional Goals: The 2015 Academy Fellows believed that a collaborative course in the first-year curriculum that builds upon integral competencies would help introduce a structure that would support further IPE in later courses. Background of CBE: The recent expansion of CBE in higher education is a result of a number of factors, including changing demographics, the increase in student debt, declining state funding, and the need for accountability markers and improved learning outcomes. First- Year Experience: First-year seminars were first designed to ease the transition to college for students and to increase both retention and persistence to graduation. Proposed CBE Course: Three foundational interprofessional global health competencies domains were implemented into the first-year experience course: collaboration, partnering and communication; ethics; and sociocultural and political awareness. Reflection and Lessons Learned: In reflecting upon the process of designing a first-year interprofessional, competency-based course, the members of the Health Educator Academy organically implemented many educator and curricular best practices that facilitate collaboration in health care delivery. Future Plans: Rather than deal with complex health issues from a single, specialized approach, healthcare providers will need to work as a team to meet the needs of patients as well as the broader community. Courses such as a first-year seminar based on interprofessional competency-based curriculum can begin the process of teaching students to think collaboratively and critically. This type of course will provide some of the tools that students will need once they leave the university and enter the professional realm.

Published: September 2021

Cancer is a leading cause of death and disability around the world. Of all cancers, breast cancer commonly ranks amongst the top three. Surgical intervention for breast cancer is common and a possible side effect of this is breast cancer related lymphoedema (BCRL). Women with breast cancer related lymphoedema commonly have regional limb swelling and pain, which can negatively impact mental and social well-being as well as upper limb function. Hydrotherapy is therapeutic modality which may be used as an adjunct to self-management strategies after the intensive phase of lymphoedema management. Yet despite its popularity, recent research has questioned its effectiveness in clinical practice. Purpose: To determine the effectiveness of hydrotherapy as an adjunct treatment to usual care on arm volume and pain when compared with usual care alone for women with breast cancer related lymphoedema. Method: A comprehensive search of eight electronic databases, including Medline, Embase, CINAHL, Scopus, Web of Science, AMED, The Cochrane Library and PEDro was completed. Studies of adult women with secondary upper limb lymphoedema following breast cancer surgery, which measured lymphoedema volume, pain, upper limb and QOL outcomes were included. Methodological quality was assessed using a modified CASP tool for randomised controlled trials. The NHMRC FORM methodology was utilised to synthesise the evidence and provide an overall grade of recommendation. Results: Four randomised controlled trials and one controlled clinical trial were included in this systematic review. Critical appraisal of the included studies revealed overall methodological quality to be moderate. Hydrotherapy interventions duration varied between 8 to 12 weeks with some similarities between outcome measures assessed. Collectively, there is mixed evidence to support the positive impact of hydrotherapy as an adjunct treatment on reducing lymphoedema volume in the short-term and emerging evidence for upper limb function, pain and QOL. Conclusion: A small number of studies have investigated the effect of hydrotherapy as an adjunct treatment in the breast cancer related lymphoedema population. Hydrotherapy could be considered as an adjunct treatment for women with breast cancer related lymphoedema, although the evidence base is mixed. Hydrotherapy may have positive physiological as well psychosocial impacts, as it is delivered in a group setting. However, the current literature base is limited by small sample size, lack of standardised exercise parameters, inadequate baseline characteristic assessment and limited long-term follow-up.

Authors: Polo Katie , Rundquist Peter , Krumdick Nathaniel , Gamble Gail
Published: September 2021

Purpose: The purpose of this study was to identify dosing levels of complete decongestive therapy (CDT) with survivors with Breast Cancer-Related Lymphedema (BCRL) and describe factors related to how occupational therapists, occupational therapy assistants, physical therapists, and physical therapists assistants with advanced lymphedema training determine dosing. Methods: An electronic survey was sent to 598 occupational therapists, occupational therapy assistants, physical therapists, and physical therapists assistants with training in lymphedema. Respondents completed questions regarding demographics, dosing practices, and factors related to dose determination in complete decongestive therapy of survivors with Breast Cancer-Related Lymphedema. Results: 107 surveys were returned (18% response rate). Most of the respondents (95.1%) reported providing less than the recommended daily dosing (7x/wk) of complete decongestive therapy to their survivors with Breast Cancer-Related Lymphedema. The mean dosing of complete decongestive therapy from respondents was approximately half of the recommended daily dosing (M=3.71). A statistically significant Pearson’s correlation was noted among frequency of dosing and treatment adherence (r=.275) and frequency of dosing and treatment readiness (r=.242). A multiple regression analysis found adherence accounted for a significant proportion of variability in dosing frequency (R²=.077; F change p Conclusions: A majority of therapists treating survivors with Breast Cancer-Related Lymphedema in an outpatient setting are not following daily recommended dosing of complete decongestive therapy. Clinicians’ dose determination is significantly impacted by their perception of a survivor’s readiness and adherence to lymphedema treatment and self-management. Comparative clinical outcomes studies of various therapeutic dosage levels (times per week) and duration (length of delivery) of complete decongestive therapy are imperative for development of best treatment protocols for survivors with Breast Cancer-Related Lymphedema. This study serves as a first step toward evidence based planning for complete decongestive therapy treatment of Breast Cancer-Related Lymphedema.

Immune-mediated hemolytic anemia leads to the premature removal of erythrocytes. It is a type 2 hypersensitivity reaction in which erythrocytes are covered by antibodies or complement and are phagocytized in the spleen or lysed within the blood vessels. It is considered of primary origin when the causes of the onset of the disease are unknown, or regarded as secondary when resulting from external antigens. The diagnosis may be therapeutic or based on the direct positive Coombs test in conjunction with laboratory findings, such as moderate to severe variable regeneration anemia, polychromasia, spherocytosis, red blood cell agglutination, hyperbilirubinemia, and hemoglobinuria. Treatment is based on immunosuppressive doses of steroidal anti-inflammatory drugs such as prednisone. This paper reports the case of an acute onset in a dog diagnosed with primary immune-mediated hemolytic anemia, presenting apathy, dyspnea, pain upon abdominal palpation, splenomegaly and pale mucous membranes. Coombs direct test was positive. Treatment started with prednisone, but as the response was not favorable, other drugs were associated to it. Evolution was unfavorable and the owner opted for euthanasia due to poor prognosis.

Physiotherapy in veterinary medicine can be used to strengthen specific muscle groups, which is particularly interesting in the conservative treatment of osteochondritis dissecans (OCD) of the humeral head. OCD is endochondral ossification disorder and is characterized by an injury to the joint cartilage. There are conservative and surgical treatments for the disease that aim to restore limb functionality and relieve pain. Building the musculature through physical rehabilitation strengthens the periarticular muscles and decreases the progression of osteoarthrosis, reducing clinical symptoms. Some of the main physical activities used in the treatment of dogs with OCD of the humeral head include active and passive movements, hydrotherapy, massage and cryotherapy.

Современное состояние европейского речного пассажирского флота и круизов
Authors: Egorov A.
Published: September 2021

Выполнено исследование европейского рынка речных круизов, проанализирован флот речных круизных пассажирских судов. Европейскому речному круизному рынку присущ ярко выраженный рост. С 2013 года происходит увеличение числа круизов, прежде всего, за счет американских туристов. В 2018 году на речных круизных пассажирских судах (РКПС) было перевезено 1,64 млн. пассажиров, на 14,6 % больше, чем годом ранее. Значительно увеличился спрос на европейские круизы у туристов из Азии, России, Скандинавии и Восточной Европы, Великобритании и Ирландии. Меняется возрастная структура пассажиров и повышается спрос на дорогие круизы. Более половины всего пассажиропотока на европейских внутренних водных путях (ВВП) приходится на Швейцарию, Германию и Францию. Практически половина всех европейских РКПС (43 % или 153 ед.) работает под швейцарским флагом. 70 % всего европейского флота (253 судна) сосредоточено в системе Дунай-Майн-Рейн. В прошлом году было сдано 20 судов, по предварительным оценкам в этом году будет запущено в работе также не менее 20 судов. Пик строительства пришелся на 2014 год (31 судно за год). В 2019 году было сдано первое на европейских ВВП трехпалубное 196 пассажирское РКПС «AmaMagna» круизной компании «Ama Waterways» с габаритной длиной 135,0 м, шириной 22 м. В 2021 году будет сдано первое европейское четырехпалубное РКПС «A-ROSA E-motion» на электродвижении для круизной компании «A-ROSA», рассчитанное на 280 пассажиров. Длина судна 135,0 м, ширина – 17,7 м, осадка – 1,7 м. Продолжает развиваться направление диверсификации европейских речных круизов. Появились речные круизы с краткосрочными выходами на морские участки. Проанализирована также группа небольших европейских РКПС пассажировместимостью 10-40 человек (европейские операторы называют их «баржами-отелями»).
Yenilenebilir Sistemlerde Maksimum Güç Noktası Takibi ve Enerji Yönetimiyle Enerji Verimliliği
Authors: ARHAN İrem , BİLGİN Mehmet Zeki
Published: September 2021

Günümüzde enerji talepleri gitgide artmaktadır. Günlük hayatta hem enerji gereksiniminin karşılanması hem de çevreye zarar vermeden kaynakların kullanılması adına yenilenebilir enerji kaynaklı sistemler tercih edilmektedir. Yenilenebilir enerji kaynaklarından güneş, günümüzde enerji üretimi için kullanılan kaynakların başında gelmektedir. Fotovoltaik (PV) panellerin çevresel kirlilik oluşturmaması, ses kirliliğine neden olmaması, yakıt gereksiniminin olmaması gibi avantajlarıyla beraber enerji dönüşümündeki verimliliklerinin yeterli seviyede olmaması dezavantajlarıdır. Bu nedenle fotovoltaik sistemlerin verimlerini yükseltmeye yönelik çalışmalar önem kazanmıştır. Fotovoltaik sistemler sıcaklık, ışınım gibi farklı çevresel parametrelere bağlı olarak çalışmaktadır. Değişken koşullarda üretilen enerji her an aynı seviyede olmamaktadır. Fotovoltaik sistemlerin maksimum çıkış gücü sağlayarak çalıştığı maksimum güç noktasının takip edilip hep bu noktada çalıştırılmasıyla sistemden maksimum oranda enerji verimi sağlanmaktadır. Çalışmada maksimum güç noktası takibi (MPPT) yöntemlerine değinilerek, MATLAB/Simulink ortamında MPPT’ li fotovoltaik sistem tasarlanmıştır. Tasarlanan sistemin, sabit sıcaklık ve değişken ışınım değerleriyle çalıştırılması sonucunda elde edilen güç değerleriyle fotovoltaik sistemlerde MPPT’ nin uygulanmasının sistemlerde enerji verimliliğini arttırdığı gözlemlenmiştir.
