Multilevel model on longitudinal data analysis in determinants of CD4 cell count among antiretroviral therapy attendant of HIV infected adults follow up in Gondar Teaching Referral Hospital, Gonder, Ethiopia
Authors: Kebede Kindu 
Published: January 2021

AbstractBackgroundHuman immunodeficiency virus attacked an immune cell and the CD4 cell which is responsible for the body’s immune to infectious agents. Acquired immunodeficiency syndrome is one of the major public health problems in Sub-Saharan Africa including Ethiopia. The main objective of this study to identify the determinants of CD4 cell count among antiretroviral therapy attendants of infected adults follow up in Gonder teaching referral hospital, Gonder, Ethiopia implemented by SAS version 94.MethodsA retrospective cohort study was conducted on 216 regular follow up patients whose age greater than 14 years from December 1, 2012, to December 30, 2017. A multilevel model was used to identify the factors of CD4 cell count of patients and it considered variability between and within patients.ResultsThe mean with a standard deviation of weight, and a hemoglobin level of patients were 55.48 (10.21), and 18.25 (33.028) respectively. This study concluded that the variation for CD4 cell count existed between patients was 63% and the remaining 37% of variation existing within patients. In this study, the random coefficient time-varying covariate model was well fitted which shows weight and hemoglobin level were statistically significant predictors at a 5% level of significance for the log of CD4 cell count of patients.ConclusionThis study shows the hemoglobin level and weight of patients were statistically significant for the log of CD4 cell count of patients follow up in Gonder teaching referral hospital, Gonder, Ethiopia. Moreover, the result of the study shows that the log of CD4 count of patients increased when hemoglobin level and weight of patients increased. Hence, intervention should be given the ways to increase weight and hemoglobin levels of patients during follow up of antiretroviral therapy.
Integrating diagnostic assessment into curriculum: a theoretical framework and teaching practices
Authors: Fan Tingting , Song Jieqing , Guan Zheshu 
Published: January 2021

AbstractCurrently, much research on cognitive diagnostic assessment (CDA) focuses on the development of statistical models estimating individual students’ attribute profiles. However, little is known about how to communicate model-generated statistical results to stakeholders, and how to translate formatively diagnostic information into teaching practices. This study proposed an integrative framework of diagnosis connecting CDA to feedback and remediation and, meanwhile, demonstrated empirically the application of the framework in an English as a Foreign Language (EFL) context. Particularly, the empirical study presented procedures of integrating diagnostic assessment to EFL reading curriculum through four phases of planning, framing, implementing, and reflecting. The results show that these procedures, influenced by the teacher’s orientation to diagnostic assessment and approach to EFL teaching, affected students’ perceptions of diagnostic assessment, their attitudes toward remedial instructions, as well as their learning outcomes on EFL reading. The results also provide evidence to the effectiveness of the integrative framework proposed in this study, showing that the framework could serve as practical guidance to the implementation and use of diagnostic assessment in the classroom.Overall, this study indicates that the diagnostic approach is a more effective way to provide instructionally useful information than other test and assessment approaches that do not differentiate strengths and weaknesses among students with the same total score.
The impact of a routine late third trimester growth scan on the incidence, diagnosis, and management of breech presentation in Oxfordshire, UK: A cohort study

Background
Breech presentation at term contributes significantly to cesarean section (CS) rates worldwide. External cephalic version (ECV) is a safe procedure that reduces term breech presentation and associated CS. A principal barrier to ECV is failure to diagnose breech presentation. Failure to diagnose breech presentation also leads to emergency CS or unplanned vaginal breech birth. Recent evidence suggests that undiagnosed breech might be eliminated using a third trimester scan. Our aim was to evaluate the impact of introducing a routine 36-week scan on the incidence of breech presentation and of undiagnosed breech presentation.

Methods and findings
We carried out a population-based cohort study of pregnant women in a single unit covering Oxfordshire, United Kingdom. All women delivering between 37+0 and 42+6 weeks gestational age, with a singleton, nonanomalous fetus over a 4-year period (01 October 2014 to 30 September 2018) were included. The mean maternal age was 31 years, mean BMI 26, 44% were nulliparous, and 21% were of non-white ethnicity. Comparisons between the 2 years before and after introduction of routine 36-week scan were made for 2 primary outcomes of (1) the incidence of breech presentation and (2) undiagnosed breech presentation. Secondary outcomes related to ECV, mode of birth, and perinatal outcomes. Relative risks (RRs) with 95% confidence intervals (CIs) are reported. A total of 27,825 pregnancies were analysed (14,444 before and 13,381 after). A scan after 35+0 weeks was performed in 5,578 (38.6%) before, and 13,251 (99.0%) after (p < 0.001). The incidence of breech presentation at birth did not change significantly (2.6% and 2.7%) (RR 1.02; 95% CI 0.89, 1.18; p = 0.76). The rate of undiagnosed breech before labour reduced, from 22.3% to 4.7% (RR 0.21; 95% CI 0.12, 0.36; p < 0.001). Vaginal breech birth rates fell from 10.3% to 5.3% (RR 0.51; 95% CI 0.30, 0.87; p = 0.01); nonsignificant increases in elective CS rates and decreases in emergency CS rates for breech babies were seen. Neonatal outcomes were not significantly altered. Study limitations include insufficient numbers to detect serious adverse outcomes, that we cannot exclude secular changes over time which may have influenced our results, and that these findings are most applicable where a comprehensive ECV service exists.

Conclusions
In this study, a universal 36-week scan policy was associated with a reduction in the incidence but not elimination of undiagnosed term breech presentation. There was no reduction in the incidence of breech presentation at birth, despite a comprehensive ECV service.
A fekete maszkulin flâneurség, városi hangtájképek és nemfehér nők hangjai Teju Cole Open city című regényében
Authors: Mózes Dorottya 
Published: January 2021

Jelen cikk a fekete maszkulin flâneurség fogalmát körvonalazza: nagyvárosi környezetben vizsgálja a flâneur rasszal és genderrel összefüggő sajátos élményeit, illetve gyakorlatait. A szociolingvisztika társas-konstruktivista poszthumanista megközelítése (Pennycook 2018), a fekete- (Glissant 1989; Crawley 2017) és a hangkultúrával (Stoever 2016; LaBelle 2010, 2018; Voegelin 2010) kapcsolatos tanulmányok megkérdőjelezik a vizualitás, a látható másság kizárólagos kategorizáló szerepét, a rassz és a gender fogalmát pedig (verbális és nem verbális eszközökkel kifejezett) nyelvi, szemiotikai (Kandiah 1998), illetve szonikus (re)konstrukcióként konceptualizálják. A butleri performativitás fogalomhoz kapcsolódóan a rekonstrukció azt jelzi, hogy a beszélők alkotó nyelvi tevékenysége képes újraalkotni, átformálni az adott társadalomban érvényes ideológiai jelentéseket. A cikk ezen értelmezési kereteket alapul véve a fekete flâneurség szonikus megalkotásának megjelenítésére és problematikájára fókuszál kortárs amerikai író Teju Cole Open City című regényében a főszereplő és narrátor figuráján keresztül. Mivel az elemzés alapvetően a fekete férfinek, Juliusnak a perspektívájára fókuszál, szükségképpen kitér a fekete és a fehér flâneur közötti különbségek komparatív vizsgálatára is. Mindezen szempontokat a városi térhez kapcsolva kutatásom a következő részkérdésekre keresi a választ: (1) mennyiben működnek a városi térben a zenei, szóbeli és más szonikus elemek olyan traumák indexeként, mint a rasszista és patriarchális elnyomás, a gyarmatosítás, az amerikai indián vagy a ruandai genocídium, a nemi erőszak; (2) hogyan találkozik a hang és a tér a rassz és a gender keresztmetszetében, mit árulhatnak el ezek a kapcsolatok a városi helyszínek és szubjektumok akusztikai és társas-társadalmi viszonyairól; (3) hogyan artikulálják a fekete flâneurnek a különböző női figurákhoz és kifejeződési formákhoz fűződő viszonyát, érzéseit a különböző szonikus elemek (a különböző zenei formák, hangok, zajok, beszédtettek és a csend).

Published: January 2021

Based on the analysis of the current situatim with gas supply in the Republic of Tuva (low gas supply to the population, lask of gas based heat generation), the article duscusses possible ways to solve the problem of gas supply to cites, towns and rural settlements of the republic in line with current trends in the development of gasification processes in the regions of Russia. The gas requirements of all categories of consumers: the population, heat generation enterprises, social and household spheres in the region are estimated. The prospects for gas supply in the centext of solving envitonmentae problems are to reduce air pollution in cities and towns. The directions of solving the problem of gasification of Tuva in the long term are substantiated, also considered option for transferring the economy of republic to the main gas supply, construction of an oil product pipeline are considered.
The following effective ways to increase the level of gasification in Tuva are identified: the realization of the potential for gas production from coal deposits, the use of thermal energy from an underground fire and the development of autonomous gasification, which can be carried out during stage I of gasification. At the second stage, it is possible to transfer the economy and social sphere to the main gas supply though the construction of Tuva gas pipeline or the oil product pipeline.
Technology Training and Empowerment for the Visually Impaired: Kenya Perspective
Authors: Were Charles Michael 
Published: January 2021

A key goal of education for any country is to make sure that every pupil has a chance to excel, both in school and life. Increasingly, a child’s success in school will determine his success as an adult; will determine whether he/she goes to college, what profession that he/she enters and how much they are paid. Kenya’s education system has laid emphasis on a cluster of science subjects that must be passed for one to be placed in a meaningful course at tertiary level, university and finally employment. The Visually impaired child has been disadvantaged and this study therefore tried to investigate why there are more street beggars who are Visually impaired as compared to other persons with disabilities in the Kenyan major towns. The study was conducted in the three towns within Kenya, namely: Kisumu, Nakuru and Nairobi. The study population was 145, and a purposive sampling was used to select the 60 respondents. The study found that the Visually impaired persons who were beggars on the street had basic education at primary level and some had form four certificate, however they had failed to gain any meaningful employment due to the growing need of technology in the work place and the increasing interest in the role of information and communication technologies for one to be employed. The study also found that as much as there is an increasing effort by the Government to have computer studies for all schools in Kenya. The Jaw’s programme is lacking in those computers and therefore the visually impaired learners have not had an access to computer education and hence the mass influx of beggars. The study recommends that of the schools where the Visually impaired learners are in inclusive education, there should be at least two computers with a Jaw programme to help the Visually impaired have an access in computer literacy and hence employment opportunity. The study also recommends that the street beggars with form four educations should be given vocational training with information technology so as to empower them with the current basic skills to compete favourable with other job seekers.
Neoliberal Globalization, Human Trafficking, and Human Security in Japan
Authors: Uddin M. Bashir 
Published: January 2021

The issues of human trafficking and human security have been inadequately addressed in the study of political economy. How and whose human security could be assessed when considering political economy of human trafficking? This paper investigates this question, especially how contemporary globalization causes human exploitation that exacerbates human insecurity. Trafficking is a global phenomenon, the origin of which could be found in the global capitalist system. This paper examines human trafficking against the backdrop of this system that is enhanced by neoliberal globalization. While debate on prostitution, migration, criminal approach, and human rights has been at the center of anti-trafficking literature and policy initiatives in Asia, the paper argues that human trafficking is the result of human insecurity and vice versa, which could be better explained through global political economy, particularly in Japan.
Super-hard coatings deposited under conditions of the dynamic shock wave and measurement features of control parameters during production
Authors: Kuzmin Oleg 
Published: January 2021

Abstract
Super-hard coatings are of increasing scientific interest as they allow synthesizing materials with unique physical and chemical properties for further application in the industry at high-speed processing or tooling. This study is aimed to investigate tetrahedral amorphous carbon (ta-C) films, as well as the dependence of the pulsation parameters on the irradiation parameters and the potential of such pulsations to be further applied in practice. The article shows that ta-C films are completely amorphous and have up to 85% of sp3 bonds. Deposited films are characterized by high compression stresses ranging within 8-10 GPa. The possibilities of reducing these stresses by thermal and pulsed laser annealing have been examined. The formation of ripples in super-hard ta-C films were studied by applying femtosecond laser pulses with a wavelength of 775 nm, an average wavelength of 387 nm, and the pulse duration of 150 fs. Obtained results demonstrated that the orientation of the pulsations on smooth surfaces is perpendicular to the vector of the electric field of the linearly polarized laser beam. Besides, the period of pulsation reduces with decreasing the laser wavelength and/or increasing the angle of laser beam incidence on the substrate.

Published: January 2021

Abstract
In this article, a fast algorithm is developed for the numerical solution of twelfth-order boundary value problems (BVPs). The Haar technique is applied to both linear and nonlinear BVPs. In Haar technique, the twelfth-order derivative in BVP is approximated using Haar functions, and the process of integration is used to obtain the expression of lower-order derivatives and approximate solution for the unknown function. Three linear and two nonlinear examples are taken from literature for checking the convergence of the proposed technique. A comparison of the results obtained by the present technique with results obtained by other techniques reveals that the present method is more effective and efficient. The maximum absolute and root mean square errors are compared with the exact solution at different collocation and Gauss points. The convergence rate using different numbers of collocation points is also calculated, which is approximately equal to 2.

Modèles logiques de la structure élémentaire de la signification: Templum, prisme sémiotique, carré sémiotique, cube sémiotique et autres
Authors: Hébert Louis , Poirier-Roy Arthur 
Published: January 2021

Résumé
La sémiotique a inventé ou utilisé plusieurs modèles logiques pour représenter la structure élémentaire de la signification. Le carré sémiotique est sans doute l’un des plus célèbres de ces modèles. Il faut se demander, devant l’importance des phénomènes triadiques, si les modèles dyadiques sont (toujours) adaptés à leur description ou s’il ne faudrait pas se tourner (aussi) vers des modèles triadiques. Or, les modèles triadiques de la structure élémentaire de la signification nous apparaissent bien moins nombreux. À notre connaissance, seule la sémiotique de Peirce et le templum de Boudon occupent cet espace autrement laissé vacant. Nous voulons ici à la fois présenter et exemplifier le templum et le compléter, en nous inspirant du carré sémiotique, pour le faire évoluer vers un « prisme sémiotique ». Nous proposerons également d’autres modèles logiques, comme le pentalemme et le cube sémiotiques. Au passage, nous étudierons plusieurs questions et problèmes – dont la décidabilité – entourant les modèles logiques. Nous ferons quelques applications sommaires de certains modèles, sur le temps, l’espace et la transcendance principalement.
Review of a Basic Phraseological Vocabulary – an Explorative Data Analysis
Authors: Hoffmann Lea 
Published: January 2021

This article addresses the question of which possibilities and limitations of frequency-based studies on the relevance of multi-word expressions open up for applied purposes. For this purpose, the corpus Ref10 of the project Wortschatzwissen.de was exploratively examined. After the development of a category system for multi-word expressions, a sample of the corpus was examined and assigned to the different categories. Subsequently, the identified multi-word expressions were compared with a phrase list of Hallsteinsdóttir, Šajánková & Quasthoff (2006). Findings suggest that the proportion of collocations is particularly high in all subcorpora and that, in addition, idioms and light verb constructions are predominant. Moreover, a large proportion of the idioms identified in the Ref10 corpus sample does not occur at all or occurs only partially, i.e. in an unlisted variant, in the phraseological optimum of Hallsteinsdóttir, Šajánková & Quasthoff (2006). This raises above all the question of how phrase variance is to be evaluated in corpus analyses and to what extent corpus linguists should rely only on basic vocabulary from the perspective of Applied linguistics.

Authors: Nunes Daiane , Melo de Araújo Marley Rosana 
Published: January 2021

No contexto do trabalho, resiliência é entendida como a capacidade do sujeito de se adaptar e fortalecer mediante experiências de adversidade vivenciadas naquele ambiente. Tendo em vista a escassez de instrumentos para mensurar resiliência nesse cenário, este estudo objetivou validar a Escala de Resiliência em amostra de 600 trabalhadores de diferentes áreas profissionais. A análise dos dados foi executada por meio de Análise Fatorial Exploratória, extração dos coeficientes alfa de Cronbach e estatísticas descritivas para caracterizar a amostra. Foram encontrados dois fatores: 1 – Autodeterminação (α: 0,76): conjunto de comportamentos e habilidades que dotam o sujeito da capacidade de ser agente causal em relação ao cumprimento de seus objetivos e metas estabelecidas (oito itens); 2 – Autoeficácia (α: 0,69): percepção do sujeito acerca de sua competência pessoal na resolução de tarefas e situações (10 itens). Assim, este estudo apresenta à comunidade científica um instrumental válido e fidedigno para uso em outras pesquisas e intervenções.

La neurodidáctica y la educación emocional para combatir el síndrome de Burnout
Authors: Marín Perabá Cristina , Zamora López Pilar 
Published: January 2021

Cada vez más son los trabajadores que sufren el síndrome de Burnout, el síndrome que provoca estrés y ansiedad por motivos laborales con carácter crónico. De entre sus causas más usuales, se encuentran hacer un trabajo que necesite mucha energía o trabajar en ámbitos que requieran mucha atención. Por su parte, el ámbito de la Neurodidáctica, se encarga de conocer el desarrollo del funcionamiento del cerebro. Si se aúnan la atención a la diversidad en los centros escolares junto con la falta de conocimiento de las características de cada una de las diversidades de los estudiantes, puede surgir en el profesor el denominado síndrome de Burnout, causado por la gran atención continuada que requiere este alumnado. En este trabajo se plantea la Neurodidáctica como ayuda para disminuir los altos niveles de estrés y ansiedad que sufre el profesorado con el síndrome de Burnout, ya que, si se conoce el funcionamiento del cerebro en el alumnado con diversidad funcional, se conocerá mejor el campo de actuación con estos discentes, y por lo tanto, disminuirán los casos de profesores con ansiedad.
