Authors: Bessa Marcelino Maia , Freitas Rodrigo Jácob Moreira de
Published: January 2021

Este estudo teve como objetivo analisar a produção científica acerca das representações sociais de estudantes sobre o HIV/AIDS. Trata-se de uma revisão integrativa da literatura realizada nas bases de dados LILASC, BDENF, SciELO, Google scholar e Index Psi Periódicos Técnico-Científicos, norteado pela questão: quais as representações sociais de estudantes sobre o HIV/Aids? Foram utilizados 6 artigos entre os anos 2002 e 2017. Estes revelaram que as representações sociais remetem-se a um problema da sociedade que assola o mundo. Estes representam desde sua identificação como doença e a morte, assim como o preconceito que as pessoas que vivem com HIV/AIDS sofrem, podendo ser associado a falta de informação por parte de quem o pratica. Foi possível identificar uma possível mudança de representação social da AIDS quanto a sua relação a homossexualidade. Fortalecimento das discussões sobre o HIV/AIDS. É preciso ainda que os conhecimentos e discussões produzidas sejam apropriados por instituições e profissionais, principalmente na prevenção da disseminação do vírus e da doença, bem como por meio da informação, desmistificar essa temática.

Published: January 2021

The productivity of lowland rice in Lebong Regency is already quite high, at an average of 5.52 tons per hectare, whereas for the productivity of upland rice is only 1.824 tons per hectare. In line with population growth in Lebong Regency, the need for food, especially rice, continues to increase. This situation certainly must be balanced with efforts to increase rice production. At Asriani et al. 2018 shows situation the production of upland rice is still very minimum. This study aims to identify the crop management in rice farming were implemented in Lebong Regency and to analyze the production and productivity of rice in each planting management. Research data are primary data and secondary data. The data analysis method consists of two, namely identification and analysis of planting management and production and productivity of rice farming in different planting management. The study of crop management pattern in Lebong Regency can explain the following conclusions (1) land management depends on the readiness of smallholder farmers who work and provide capital so that the cultivated land is only limited to the ability of capital owned by smallholder farmers which is influenced by socio-economic, technical, and market factors, (2) less optimal maintenance of food production centers, especially in irrigated rice fields, so that efforts should be made to increase production and productivity

Authors: Asiba Widya Pratisca
Published: January 2021

Sangat mustahil rasanya, bila suatu individu maupun kelompok tidak pernah mengalami perkembangan. Perkembangan merupakan satu perubahan yang terjadi dari waktu ke waktu dan biasanya lebih mendekati ke arah yang lebih maju. Pada masing-masing negara di belahan dunia, sudah banyak mengalami perkembangan di berbagai bidang, tidak terkecuali pada bidang teknologi. Kita ketahui bahwa teknologi pada dunia pendidikan dari zaman ke zaman sangat mengalami perubahan, seperti pada media belajar yang digunakan zaman dulu sangatlah manual, yaitu kapur dan papan tulis hitam. Berbeda halnya dengan zaman sekarang, sudah menggunakan media belajar seperti laptop dan proyektor yang terkesan canggih. Selain itu, sumber belajar yang diperoleh pada zaman dulu, peserta didik harus rajin membaca buku dan lain sebagainya. Namun, zaman sekarang dapat menemukan sumber belajar hanya melalui artikel dan video-video pembelajaran yang tersebar luas di internet. Sudah jelas, bahwa sebagian besar peserta didik pada zaman sekarang telah menguasai teknologi sebagai sumber belajar. Tetapi, peran guru yang lebih paham dalam menggunakan teknologi juga sangat dibutuhkan, agar dapat membimbing siswa-siswanya. Apalagi, seluruh dunia sedang mengalami pandemi covid-19 yang sangat berbahaya. Suka atau tidak suka, seluruh sekolah ditutup sementara untuk menghentikan penyebaran covid-19 dan menghimbau menggunakan model pembelajaran daring. Saat itulah, teknologi semakin menjadi kebutuhan primer bagi peserta didik maupun guru.

Using Repetitive Control with Force Feedback to Reduce Impedance of Exoskeletons for Gait Training
Authors: McGrath Robert , Sergi Fabrizio
Published: January 2021

Transparent interaction, or the reduction of human-robot interaction forces, is an important quality of gait training exoskeletons. In this paper, we investigate the feasibility of using a repetitive controller for reducing impedance of gait training exoskeletons using force feedback. We used a two-mass spring damper model system, and simulated the application of repetitive force controllers with the objective of reducing the end-point impedance of the distal mass. We designed and applied three repetitive controllers: a 1st order, a 2nd order designed for random signal period error, and a 2nd order designed for constant signal period error. We compared these three repetitive controllers subject to plant model parameter error, random signal period error, and constant signal period error. Numerical simulations under nominal conditions show that via repetitive force control, it is possible to reduce the endpoint impedance to the targeted magnitude and RMSE force below the limit achievable with force controllers while guaranteeing passivity. Furthermore, we established that the application of a 2nd order repetitive controller designed for random period error is highly robust to random period error - exceeding the performance of the passive proportional controller up to 30% error of nominal frequency. Furthermore, this 2nd order repetitive controller designed for random period error maintains a 100% convergence rate through 60% plant parameter error.
Primary school mathematics during Covid-19: No evidence of learning gaps in adaptive practicing results
Authors: Meeter Martijn
Published: January 2021

During the spring of 2020, the Covid-19 pandemic induced many governments to close schools for many months. In the Netherlands, primary schools were closed during a lockdown lasting from March until June. While education was continued online, evidence so far suggests that learning has suffered from the lockdown. Here, we report results from Dutch primary schools that relied on adaptive practicing software for teaching mathematics. The software, installed on tablets that could be taken home by the pupils, continued to be used during school closures. Performance was tracked throughout the lockdown for 53,656 pupils in grades 2 through 6 from 810 schools, and compared to performance of similar pupils in the preceding year. While performance up to the lockdown was similar for school year 2019-20, during the lockdown learning was faster that it had been in 2018-19, contradicting results reported so far. These enhanced gains were correlated with increased use, and remained after the lockdown ended. Pupils ended the year with a higher proficiency score than was reached in earlier years. This was the case for all grades but more so for lower grades, for strong and weak students but more so for weak students, and less so for students in schools with disadvantaged populations than in schools with non-disadvantaged populations.
Are Children’s Judgments of Another’s Accuracy Linked to Their Metacognitive Confidence Judgments?
Authors: Baer Carolyn , Malik Puja , Odic Darko
Published: January 2021

The world can be a confusing place, which leads to a significant challenge: how do we figure out what is true? To accomplish this, children possess two relevant skills: reasoning about the likelihood of their own accuracy (metacognitive confidence) and reasoning about the likelihood of others’ accuracy (mindreading). Guided by Signal Detection Theory and Simulation Theory, we examine whether these two self- and other-oriented skills are one in the same, relying on a single cognitive process. Specifically, Signal Detection Theory proposes that confidence in a decision is purely derived from the imprecision of that decision, predicting a tight correlation between decision accuracy and confidence. Simulation Theory further proposes that children attribute their own cognitive experience to others when reasoning socially. Together, these theories predict that children’s self and other reasoning should be highly correlated and dependent on decision accuracy. In four studies (N = 374), children aged 4-7 completed a confidence reasoning task and selective social learning task each designed to eliminate confounding language and response biases, enabling us to isolate the unique correlation between self and other reasoning. However, in three of the four studies, we did not find that individual differences on the two tasks correlated, nor that decision accuracy explained performance. These findings suggest self and other reasoning are either independent in childhood, or the result of a single process that operates differently for self and others.
THE PROBLEM OF IMITATING MODELS IN THE POETOLOGY OF FRENCH CLASSICISM
Authors: Makhov A.E.
Published: January 2021

The article shows how the idea of imitatio auctorum, known since antiquity, was interpreted in the poetology of French classicism. The opposition of «servile» and free imitation, as well as the correlation between the concept of imitation and the notions of invention, translation, copying, theft and conquest come under scrutiny. A distinction is drawn between different objects of imitation. Poetologists recommend imitating not so much the specific thoughts and expressions of the original as its general idea, «spirit», manner, and also the very creative strategy of the author. In the latter case the object of imitation is not the completed work, but the process of its creation. The imitation strategy was justified by the argument of reciprocity: we imitate the ancients in the same way as the ancients themselves imitated their predecessors.
OSCILLATION OF THE IMAGE: IMAGES OF “WRITER” (BY) PETER HANDKE IN MASS MEDIA AND IN W.G. SEBALD’S ESSAYS
Authors: Sokolova E.V.
Published: January 2021

This article investigates reception of the figure of Austrian writer Peter Handke (b. 1942), the Nobel Prize winner in Literature in 2019, within discourses of actual German culture (in «literary» and «mass media» contexts) in parallel with his own understanding of the Writer’s Mission, its aims, ideals, and complications. Being a Writer as a way to get through the totality of «invalid communication» («verhinderte Kommunikation») in the real world is the most important topic of Handke’s own literary creation: beginning with «The Goalie’s Anxiety at the Penalty Kick» (1970), «Slow Homecoming» (1979), «Repetition» (1986), «The afternoon of a writer» (1987) and ending in his later texts. Besides the above mentioned works of Peter Handke, the present paper analyzes three essays on his work written by a world famous German writer and literary scholar W.G. Sebald (1944-2001), who took close to his heart the described topic as well (especially the tradition of Linguistic Scepticism going back to the ideas of Ludwig Wittgenstein). The paper also considers a number of publications in the German press in October 2019 dealing with Peter Handke being awarded the Nobel Prize and the heated debate that followed.

Chhoyla and Kachela are indigenous and popular meat dishes in the Newar community that are widely consumed in Kathmandu valley. The present study was carried out to investigate the microbial quality of Chhoyla and Kachela from different parts of the valley. The mean total aerobic plate count of Chhoyla and Kachela ranged up to 6.38 and 6.54 log10 cfu/g respectively. The mean total coliform count of Chhoyla and Kachela ranged up to 5.25 and 5.82 log10 cfu/g respectively. Coliform (93%), Staphylococcus aureus (75%), Salmonella Typhi (12%), Salmonella Paratyphi A (5%) and Shigella spp (3%) were isolated from Chhoyla. Likewise, bacteria isolated from Kachela were coliforms (97%), Staphylococcus aureus (86.66%), Salmonella Typhi (15%), Salmonella Paratyphi A (8%) and Shigella spp (7%). High microbial load and the potent human pathogens isolated from these meat products indicate potential risk of food borne diseases.
Study on Post Harvest Losses in Potato in Different Storage Conditions
Authors: Khanal Shraddha , Bhattarai Kabindra
Published: January 2021

The study aimed to conduct a comparative study of three most common potato storage conditions (in-house store, in-basket store and cold store) and to find the most suitable storage condition for farmers. The experimental work involved post-harvest loss assessment and study of pattern of respiratory and reducing sugar level for sixty days storage period. Total loss was lowest (4.38%) for cold stored potatoes and highest (13.04%) for in-house stored potatoes. Reducing sugar accumulation was least (0.65%) and remained almost constant throughout study period for in-house stored potatoes. Reducing sugar accumulation gradually increased and was maximum (1.04%) for cold stored potatoes. Respiratory rate was least in cold stored potatoes which gradually decreased and reached 3.17mg CO2/kg/hr at the end of sixty days storage. Respiratory rate was maximum for in-basket stored potatoes which reached up to 6.55 mg CO2/kg/hr at the end of storage. Storage loss and respiratory rate are minimum for cold stored potatoes but showed high sugar accumulation. In-house storage do not suffer from excessive sugar accumulation but storage loss is maximum of all. In case of in-basket storage, besides being cheap and feasible, there is no problem of sugar accumulation and storage losses was also significantly lower than in-house storage.
Koronarzeczywistość – o nowych złożeniach z członem "korona-" w dobie pandemii
Authors: Cierpich-Kozieł Agnieszka
Published: January 2021

The article focuses on the Anglicism "koronawirus" in the Polish language. Its principal aim was to excerpt the compound nouns with the productive stem "korona-", to discuss their status, and to group them into semantic fields. Among such neologisms, numerous hybrid creations, a few pseudoanglicisms, as well as one loanword were found. They can be grouped into at least 11 semantic fields referring to socioeconomic, political and cultural reality in the time of COVID-19 pandemic. Moreover, the Polish adjective "koronawirusowy" is discussed. As a constituent of a Polish noun phrase, it usually complies with the English sentence structure. Also, basic comparative research on the productivity of the stem "korona-", and its foreign language counterparts in Polish, English and German was conducted.
A Canadian survey on knowledge of non-alcoholic fatty liver disease among physicians
Authors: Sebastiani Giada , Ramji Alnoor , Swain Mark G , Patel Keyur
Published: January 2021

BACKGROUND: In Canada, non-alcoholic fatty liver disease (NAFLD) is the most frequently occurring liver disease, affecting one in four Canadians. NAFLD can in turn evolve into non-alcoholic steatohepatitis (NASH) and cirrhosis. No study in Canada has investigated knowledge of NAFLD among physicians. METHODS: Primary care physicians (PCPs); specialists in internal medicine, gastroenterology, and hepatology; and hepatology nurses who were members of the College of Family Physicians of Canada, Canadian Association for the Study of the Liver, or Canadian Association of Hepatology Nurses were invited to participate in this web-based survey. RESULTS: Of 650 invited physicians and nurses, 214 (33%) responded and 171 (26%) completed the whole survey. Overall, 51% of the respondents were PCPs, 38% were specialists, and 11% were nurses. Of these, 58% of PCPs, 28% of specialists, and 39% of nurses responded that they were only somewhat familiar or unfamiliar with NAFLD. Moreover, 53% of PCPs, 20% of specialists, and 35% of nurses thought the prevalence of NAFLD in Canada was 15% or less. Also, 42% of respondents thought that NASH could be diagnosed by imaging or blood tests. Finally, more than 40% of PCPs, 22% of specialists, and 33% of nurses thought that metformin and statin were treatments for NASH. CONCLUSIONS: This survey shows that a significant proportion of Canadian physicians and nurses managing patients with NAFLD are not very familiar with the disease. This study emphasizes the need for further provider education, national practice guidelines, and improved treatment options.

Published: January 2021

Technique: This chest tube anchoring technique differs from other techniques by introducing 2 layered
closure to avoid wound healing complications such as hypertrophic or keloid scar and to achieve airtight
closure. The first suture to be used is a monofilament synthetic absorbable 4/0 suture – Monocryl (Johnson
& Johnson, New Jersey, USA) that is passed as a buried stitch in the dermal layer. The second suture to be
used is a monofilament non-absorbable 3/0 suture – Prolene (Johnson & Johnson, New Jersey, USA) that is
passed around the chest tube incision in a horizontal mattress manner taking the muscle/fascia and skin
layers. The chest tube is then anchored with a 2/0 silk suture with a mesentery. The three suture ends are
secured and wrapped around the chest tube with Steri-Strips™ (3M™, Minnesota, USA). Two long
dressings are sandwiched together, partially on skin and partially on the tube as dressing anchors.
Results: This technique has shown good results with no complications. Routine chest radiograph and
physical examination showed no signs of pneumothorax or discharge from the wound nor any wound
healing complications.
Conclusion: This chest tube anchoring and closure technique is secure and produces an aesthetic pleasing
scar that does not require any expensive sutures or special skills.

The article investigates the asymptotic behavior of the solution to reconstructing the boundary conditions and the right-hand side for second-order differential equations with a small parameter at the highest derivative, which have an initial jump. Asymptotic estimates of the solution of the reconstruction problem are obtained for singularly perturbed second-order equations with an initial jump. The rules for the restoration of boundary conditions and the right parts of the original and degenerate problems are established. The asymptotic estimates of the solution of the perturbed problem are determined as well as the difference between the solution of the degenerate problem and the solution of the perturbed problem. A theorem on the existence, uniqueness, and representation of a solution to the reconstruction problem from the position of singularly perturbed equations is proved. The results obtained open up possibilities for the further development of the theory of singularly perturbed boundary value problems for ordinary differential equations.

Published: January 2021

A semi-periodic initial boundary-value problem for a fourth-order system of partial differential equations is considered. Using the method of functional parametrization, an additional parameter is carried out and the studied problem is reduced to the equivalent semi-periodic problem for a system of integro-differential equations of hyperbolic type second order with functional parameters and integral relations. An interrelation between the semi-periodic problem for the system of integro-differential equations of hyperbolic type and a family of Cauchy problems for a system of ordinary differential equations is established. Algorithms for finding of solutions to an equivalent problem are constructed and their convergence is proved. Sufficient conditions of a unique solvability to the semi-periodic initial boundary value problem for the fourth-order system of partial differential equations are obtained.

This paper is devoted to the study of internal boundary layer. Such motions are often associated with effect of boundary layer, i.e. low flow viscosity affects only in a narrow parietal layer of a streamlined body, and outside this zone the flow is as if there is no viscosity - the so-called ideal flow. Number of exponentials in the boundary layer is determined by the number of non-zero points of the limit operator spectrum. In the paper we consider the case when spectrum of the limit operator vanishes at the point To study the problem the Lomov regularization method is used. The original problem is regularized and the main term of asymptotics of the problem solution is constructed as the low viscosity tends to zero. Numerical results of solutions are obtained for different values of low viscosity.

Introduction: The utilization of fossil fuels in coal-fired power plants (CFPPs) for electricity generation could lead to the release of additional natural and artificial radioisotopes into the surrounding environment and consequently, increase the gamma dose rate at these areas.
Methods: In this study, the geological variation of gamma dose rate in the vicinity of Duyen Hai CFPP complex and Vinh tan CFPP complex were evaluated.
Results: The obtained gamma dose rates were in the range from 0.07 to 0.22 μSv h-1 with the average value of 0.13 μSv h-1 for Duyen Hai area and in the range from 0.14 to 0.34 μSv h-1 with the average value of 0.21 μSv h-1. The results indicated that the gamma dose rate in Vinh tan area is higher than the corresponding value of Duyen Hai area. Both natural aspects, such as the geological differences as well as geomorphology and weathering process, and anthropogenic aspects, such as the difference in operational scale, coal consumption and ash discharge between Duyen Hai and Vinh Tan CFPP complex, might significantly contribute to the variation of gamma dose rate in the investigated locations.
Conclusion: Overall, the calculated outdoor annual effective doses of two studied areas showed that the radiological impacts of both Duyen Hai and Vinh Tan CFPP complex to the environment and public health are negligible.

The penetration of distributed generators (DG ) into the distribution etworks (DN) greatly improves the reliability of electricity supply and reduces power loss. However, the operation of these DGs can also make the protection of distribution etwork more complex. This paper will examine the effects of two DG types on the protection of DN by analyzing the solution called Fault Location, Isolation and Service Restoration (FLISR). The FLISR approach considers DGs as auxiliary sources for the post-fault restoration plans in order to minimize the number of interrupted customers and unserved energy. Moreover, the combination of setting value of the overcurrent relay and the statuses of switching device and the loss voltage warning signal are used to detect and identify types of incidents in the distribution etwork with DGs. A two-constrained objective function will be solved to find possible plans for fault isolation and service restoration. There are six performance indices (PIs) selected for post-fault service restoration processing. The simulation results for the 22kV distribution network with integrated DG were performed by using E-terra software to validate this FLISR approach. To be concluded, the FLISR approach well adapt to the integration of DG into the DN and also helps to identify risks from false protection-coordination. On the other hand, it also helps to quickly detect and identify types of incidents as well as evaluate service restoration plans after incidents of distribution etwork with DG less than two minutes.

For the first time, an environmentally friendly and effective procedure to produce high-value engineering aerogels from fly ash (FA) has been developed by dispersing FA particles into a mixture of biodegradable polyvinyl alcohol (PVA) and carboxymethyl cellulose (CMC), followed by freezedrying. The effect of FA content on the physical properties, morphology, mechanical strength, and thermal conductivity of FA aerogels is also studied comprehensively. The lightweight FA aerogels show a low density of 0.072 – 0.093 g/cm3 with high porosity of 94.94 – 95.78%. The morphology of aerogels shows the uniform distribution of FA particles in PVA-CMC matrixes that creates a porous structure with a pore size of 2-5 mm. Therefore, the FA aerogels exhibit good heat insulation with extremely low thermal conductivity of 0.040 – 0.047 W/m.K at ambient temperature and pressure that is comparable to some commercial insulation materials such as mineral wool, fiberglass, expanded polystyrene, and other silica-based aerogels from waste. Moreover, the compressive modulus of FA aerogels is about 67.73 – 254.75 kPa indicating their excellent mechanical properties under 1 kN vertical compression. The experimental results indicate the significant better durability of FA aerogels than that of previous aerogels from other wastes such as sugarcane bagasse (88 kPa), pineapple leaf fibers (1.64 – 5.34 kPa), recycled polyethylene terephthalate (1.16 – 2.87 kPa), spent coffee grounds (5.41 – 15.62 kPa), and silica – cellulose (86 – 169 kPa). It is concluded that FA aerogels are a promising candidate as a lightweight thermal insulating material.

The aim of the article is to analyze the literature and scientific publications on the effectiveness of the heat pump in heat supply systems and to study the efficiency of using the steam compression cycle of a heat pump in a heat supply system. Тo conduct energy and exergy analysis of heat pump efficiency indicators, the working fluid of which is freon R134a, when using natural waters as a source of low-potential thermal energy. The article analyzes the literature sources and scientific publications on the effectiveness of the heat pump in heat supply systems. The results of research of efficiency of application of the heat pump in systems of heat supply at use of natural waters as a source of low-potential thermal energy are presented. Energy and exergy analysis of heat pump efficiency indicators, the working fluid of which is R134a freon, was performed. The energy efficiency of the heat pump cycle was determined by the conversion factor of the heat pump. The thermodynamic efficiency of the heat pump in heat supply systems was evaluated using exergetic efficiency, which is one of the main indicators of the efficiency of heat pump processes and cycles. The calculation of energy indicators of the heat pump, such as: specific heat load in the evaporator and condenser, as well as the conversion factor of the heat pump. The calculation of exergetic efficiency for ambient temperature from +10 to -10 ºC. Thus, the energy and exergy analysis of the efficiency of the heat pump, the working fluid of which is Freon R134a with a conversion factor = 4.8. This indicates that the heat pump is a reliable, highly efficient, environmentally friendly source of energy for use in heating systems. A heat pump heating system will always consume less primary energy than traditional heating systems if natural water is used as a low-temperature heat source for the heat pump. The efficiency of the steam compression cycle of the heat pump largely depends on the temperature of low-potential heat sources. The use of HV in heating systems reduces greenhouse gas emissions compared to conventional types of heat supply, which is relevant to the ecological state of the environment.
