There is a difference among the three groups in terms of length of English study. The freshman group showed slightly higher language attitudes compared with those of the other two groups.
Allegiance Bias and Treatment Quality as Moderators of the Effectiveness of Humanistic Psychotherapy: Protocol for a Systematic Review and Meta-Analysis (Preprint)
Authors: Schünemann Olivia , Jansen Alessa , Willutzki Ulrike , Heinrichs Nina
Published: July 2019

BACKGROUND

In many countries, humanistic psychotherapy (HPT) is viewed as a broad psychotherapeutic approach and is accepted in health care systems. To qualify for reimbursement by health insurance in Germany, psychotherapy approaches have to be evaluated positively by the German Scientific Board of Psychotherapy (GSBP). The GSBP examined HPT and its subapproaches based on an application by a number of professional organizations affiliated with HPT (Work Group Humanistic Psychotherapy, WGHPT). The GSBP came to the decision that none of the HPT subapproaches provided sufficient evidence to be evaluated as evidence based. Potential reasons for the discrepancy between international recognition of HPT and GSBP’s decision will be explored: researchers’ allegiance may have led to a risk of bias disadvantaging HPT. Furthermore, the evaluation criteria of the GSBP did not systematically consider whether HPT was conceptualized bona fide and implemented with sufficient treatment integrity in the studies.

OBJECTIVE

This systematic review will re-examine the studies included in the review of the GSBP. Within 2 comparisons (HPT vs control and HPT vs other psychotherapeutic interventions), we will examine moderating effects of treatment quality (bona fide and treatment integrity) and allegiance on the effectiveness of HPT.

METHODS

This review is based on the prior systematic review by the GSBP. The GSBP examined randomized controlled trials (RCTs) and studies with non-RCTs of HPT interventions for individuals with mental disorders. All studies suggested by the WGHPT were included; moreover, the GSBP conducted searches in standard electronic databases (Cochrane Central Register of Controlled Trials, MEDLINE, PsycINFO, and PSYNDEX) and handsearches in relevant systematic reviews and contacted experts. A total of 2 independent GSBP reviewers performed study screening using a structured form. On the basis of the prior work of the GSBP, all studies that were positively screened by the GSBP will be included in this review. Data will be extracted independently by 4 authors. Standardized mean difference will be calculated, and possible publication bias will be tested using funnel plots and Egger test. A priori defined subgroup or meta-regression analyses will be performed for treatment quality, allegiance, type of nonactive control, study quality, type of subapproach, and target population (children and adolescents or adults).

RESULTS

The GSBP identified 115 eligible studies that will be reanalyzed in this systematic review.

CONCLUSIONS

Results about moderator effects of treatment quality and allegiance will provide important information about their impact on the evaluation of HPT and other psychotherapy approaches and can be used for further evaluation methods.
Effectiveness of a Digital Lifestyle Change Program in Obese and Type 2 Diabetes Populations: Service Evaluation of Real-World Data (Preprint)
Authors: Idris Iskandar , Hampton James , Moncrieff Fiona , Whitman Michael
Published: July 2019

BACKGROUND

The prevalence of type 2 diabetes mellitus (T2DM) and obesity is increasing, and the way people interact with health care is evolving. People traditionally access advice and support to improve their lifestyle and learn more about the self-management of T2DM in a face-to-face setting. Although these services have a strong evidence base, they have limitations for reaching specific groups of people. Digital programs could provide a new delivery model to help more people access health education and behavior change support, but long-term data supporting these programs are limited.

OBJECTIVE

The purpose of this service evaluation was to analyze the weight change of people who participated in OurPath (also known as Second Nature), a UK-based digital lifestyle change program, for either weight management or diabetes-related weight management and structured education at 6 and 12 months.

METHODS

Participants either paid to access the program privately (self-funded clients) or were referred by their general practitioner to participate in the program free of charge (funded by the National Health Service). Additional follow-up support was provided to help people to maintain lifestyle changes. To retrospectively assess potential weight loss, the analysis included data from participants who submitted weight readings at baseline and 6 and 12 months after starting the program. Changes in weight after 6 and 12 months were primary outcome measures.

RESULTS

For the 896 participants who submitted baseline and 6- and 12-month data, a significant change in mean weight of −7.12 kg (−7.50%; SD 6.37; P<.001) was observed at 6 months. Data from the same participants at 12 months showed a change in mean weight when compared with a baseline of −6.14 kg (−6.48%; SD 6.97; P<.001).

CONCLUSIONS

The data presented here had several limitations, and there were too many uncertainties to make any reliable conclusions. However, these results suggest that digital lifestyle change programs could provide a new way to help people to access nutritional advice and support to achieve weight loss. Further research into digital education and coaching platforms is needed to establish their effectiveness.
TEACHING LITERATURE THROUGH TRANSLATION. JOHN MILTON, DYLAN THOMAS AND T.S. ELIOT: PARALLELS WITH THE CORDOVAN SCHOOL OF MODERN POETRY
Authors: Torralbo Caballero Juan de Dios
Published: July 2019

Literature is usually taught using primary sources written in the language of the literature being taught. This pedagogical proposal is based on translations of literature, advanced as a didactic element enhancing literature lessons. More specifically, this work focuses on English literature translated into Spanish and published in the Cordovan journal Cántico, in  order to explore how the translations of international works can be valuable elements in the teaching of Literature. To achieve these objectives some of the translations of the English works appearing in Cántico are studied: two fragments of John Milton, a poem by Dylan Thomas, and another poem by T.S. Eliot. The final conclusion drawn is that the interpretation of the original poems, their poets, and their context, as well as a presentation of the context in which these poems were translated, are pedagogical undertakings that enhance the teaching of foreign literature, and literature in general.

Authors: Korol Tetiana
Published: July 2019

The given paper focuses on the analysis of a translation project as a powerful assessment tool that can be easily integrated into prospective philologists’ university training in order to enhance its quality and bring its outcomes into line with global industrial needs and requirements. With this aim, substantial translation pedagogy experience of project-based learning is consolidated from the viewpoint of action-oriented, student-centered, situated, experiential and reflective approaches. Translation project properties, design features, role and function distribution peculiarities typical for global professional environment are considered. The received findings are transferred and adjusted to the current terms and conditions of prospective philologists’ training in Ukrainian higher educational setting. As a result, a working classification of translation project varieties to be developed and implemented into training process at different training stages is suggested. Their functions and potential usage as a flexible assessment framework is specified. The translation project opportunity for the arrangement of not only formative but summative assessment as well is substantiated due to its contrasting to the existing examination practices. Finally, the idea of cross-assessment as the complex assessment procedure conducted from different perspectives (hetero, self- and peer-assessment) with the help of versatile tools and instruments (incorporated into single flexible translation project) is introduced.

Published: July 2019

A sociedade brasileira, bem como a sociedade global, vivem hoje uma crise conjuntural que faz (re)pensar o modelo de Estado vigente, em face à nova concepção e dinamicidade das relações sociais marcadas pela fluidez e volatilidade. As complexas questões de diversidades de raça, gênero, religião, condições econômicas e financeiras, revelam a hipossuficiência econômica, provocada pelo modelo globalizado, que de forma desigual e injusta distribui bens e serviços. Seguindo este ideário, o presente artigo tem como objetivo demonstrar, através de um estudo bibliográfico que segue o método hipotético dedutivo, que é por meio da implementação e positivação dos direitos fundamentais, que o Estado deve(ria) proporcionar de forma equitativa uma melhor qualidade de vida, com prestações estatais afirmativas e inclusivas, destacando-se o acesso à saúde pública. Logo, quando o Estado não garante um direito fundamental, acaba por não permitir também a efetivação dos direitos humanos, privando uma grande parcela da população de dispor de saúde e, consequentemente, de uma vida digna. Discutir o contexto das afirmações positivas na seara social, perpassando por uma análise da (in)atuação do Estado por meio da crise dos Poderes e do sistema político e social vigente é essencial no contexto global. Portanto, verificou-se que a atuação do Judiciário no sistema de saúde é para suprimir as demandas dos outros Poderes, saindo da sua esfera de atuação e resolvendo problemas pontuais e individuais. Assim, uma das questões mais recorrentes é a judicialização de demandas sanitárias, cujo principal motivo é a não prestação de direitos fundamentais sociais pelo Estado.
CHARACTERISTICS OF VARIABILITY OF THE HEART RHYTHM IN PRESCHOOL CHILDREN WITH DIFFERENT SPEECH DISORDERS IN ARCTIC
Authors: Kalashnikova I. V. , Nikanov A. N.
Published: July 2019

The Murmansk region is characterized by a number of speciﬁc climatic and geographical features: a polar night, a long snowy period, an unstable geo-heliophysical setting. All of the above factors have a negative impact on children with disabilities. The article describes the application of the method of analysis of heart rate variability to assess the dynamic changes in the functional state of the body of preschool children with general speech underdevelopment, as well as with stuttering. The work was carried out on the Kola Peninsula in the period of the exit from the «polar night», when exacerbations of somatic diseases are most often recorded in children, and there is a decrease in the immunological reactivity and adaptation potential. The main purpose of this work was to conduct research on the selection of methods for the functional diagnosis of a child’s body in the Kola North to track the state of the state during the educational process on the basis of a preschool institution during the most unfavorable periods. Functional diagnostics included weekly dynamic measurements of the functional status of children of both groups on a non-invasive cardiac rhythmograph, followed by mathematical processing of the main cardiorhythmographic parameters. The use of heart rate variability analysis makes it possible to identify differences in the functional state of preschool children with various speech disorders associated with the nosological structure of the defect. In addition, the use of this method allows you to track changes in the state of children in the course of the educational process in preschool institutions and to adjust the ﬂow of information, taking into account the individual characteristics and adaptive capacities of children with speech disorders.

Published: July 2019

The improvement of tactics of surgical treatment of patients with tibial distal metaepiphysis fractures with the aim of improving treatment outcomes and reducing the number of complications seems to be a topical and priority task of treatment activity. This is due to the following reasons: a large number of unsatisfactory results, due to the massive destruction of the articular surface of the ankle joint; reduction of labor activity in victims with disability, and so on. Surgical treatment of victims of the proﬁle under consideration is among the most complex tasks, the solution of which often causes objective difficulties, including the timing of the operation, the choice of rational access, osteosynthesis techniques, and the state of soft tissues. In modern conditions in various ﬁelds of medicine, advanced digital technologies are increasingly used. The main idea of their use is the possibility of excluding the «human factor” at various stages of medical care planning. As a result, medicine acquires completely new possibilities in modern conditions. In many activities, it is simply impossible to do without digital technology. This process invariably involves signiﬁcant changes in medical theory and practice. In accordance with these trends, we ﬁrst created a computer program for collecting, analyzing and evaluating data from a primary, follow-up examination and forecasting the results of treatment of victims with fractures of the distal tibial metaepiphysis. In the future, the developed computer program can form the basis of a large-scale platform on the Internet in order to exchange practical experience and jointly improve the ways of development in this area.
CALCULATION OF CONTROL AND ACCEPTABLE LEVELS OF RADIATION FACTORS FOR NUCLEAR PROPULSIONS

Published: July 2019

In accordance with requirements of regulatory and guideline documents on radiation safety for controlled radiation factors for the purposes of operating control, controlled and acceptable levels are established. Any excess of these levels requires the determination of the causes and implementation of actions designed to eliminate the excess. The paper presents the method of calculation of these levels and establishing the levels in practice at the present time, disadvantages of accepted regulations are analyzed. It was shown that existing documents do not take into account some circumstances that deﬁne the radiation safety test procedure. In a number of measured control points of the radiological situation and staff radiation exposure, the values of controlled parameters are independent of reactor system mode. In the same points that show the dependence of measured data on a reactor power level, values of controlled parameters may also depend on a mode of pumps and puriﬁcation system. Furthermore, real-time measurements review has showed that beyond the range of lower limit of measuring range of veriﬁcation means in the range with nonspeciﬁed error, the measured data variance is described by mean value and acceptable error. At the same time, a mean value may be a lower order to lower limit of measuring range. Setting a value of controlled level equal to a sum of a mean of double or tripled root-mean-square deviation depending on the accepted conﬁdence level, a possibility of earlier detection of controlled level excess emerges. In this situation, an exact absolute value of a controlling parameter is not essential as that radiation factor level poses no hazard to life. It is important to capture the onset of signiﬁcant increase of radiation factor i.e. change of radiological situation.

Combustion of coals and biomass in boiler furnaces leads to formation of fireside deposits on irradiated and convective surfaces. This problem is not a new one, but it became one of the main operational problems in boilers using low rank coal and some sort of biomass. In the paper presented are the results of research of ash deposit processes in laboratory conditions. An experimental furnace was used for these purposes. The experiments were performed on a tubular experimental furnace which ensures appropriate temperature and mass transfer conditions for physical and chemical transformations of the mineral matter of fuel as in real conditions. The main working parameters can be varied in wide ranges. The influence of grinding fineness, excess air and wall surface temperature was analysed. Also, an ash related problems during coal and biomass combustion was considered. Key empirical correlations for slagging and fouling were tested. Two types of Serbian coals (Kolubara and Kosovo) and several biomasses were analysed. It was shown that many sorts of biomass and Kosovo coal have a great propensity to slagging and fouling.

This paper presents the results of calculation system of main processes in power steam boiler, before and after application of air staging. Modified air injection scheme was implemented during 2015 on the power steam boiler within unit 1 of TPP Kostolac B. Measurements performed on site showed that applied reconstruction led to a permanent loss of the steam boiler power. This study was performed in order to define the cause of such an occurrence and to consider the possibility for regaining the designed steam parameters along with keeping NO concentration in prescribed limits. This paper x discusses the influence of repositioning the air injection location on processes within the furnace. Furthermore, the influence of the redistribution of injected air-flow along the furnace height on important boiler operation parameters has been analyzed. Analysis showed that, with appropriate dosing of air along the height of the existing furnace, it is possible to achieve the optimum of the boiler's operation parameters. Results of research showed that air staging throughout the furnace height in best test case additionally reduces NO concentration (195-225 mg/Nm3) and increases the power of x considered boiler (828.8-751.1 MW) with an insignificant decrease of the boiler's efficiency (86.27-86.77%). Furthermore, the designed temperatures of superheated (540-498?C) and reheated (540-518?C) steam have been reached again, whereby the safety of the boiler's operation has been significantly increased. Results of this study improve the present explanation of the processes occurred in the furnace with applied primary measures. They also give directions on defining the most influential parameters on considered processes with the final purpose to increase the efficiency and availability of the entire plant.

Turbulent flame-oscillation frequency and combustion efficiency are the important parameters in combustion. It is a useful study to judge combustion efficiency by intuitive flame frequency. Based on a combustion wind tunnel experimental set-up, the variation law of combustion flame-oscillation frequency and combustion efficiency using external wind speeds was studied via the color flames image sequence of oil pan combustion and flue gas composition. The oscillation frequency was calculated with the upper edge of the fire plume which recorded flame image sequence using a high-speed video, combined the MATLAB image processing technique. The combustion efficiency was calculated combined with the C and H element mass of the liquid fuel in the oil pool and CO2 and H2O concentrations in the flue gas. The results show that the oscillation frequency of the flame revealed a tendency to increase followed by a decrease with increasing wind speed, while the overall trend of combustion efficiency increased first and then decreased. The combustion efficiency could be judged by observing the oscillation frequency of the flame image. In addition, the combustion efficiency may ensure in right way when the turbulence oscillation frequency of the oil pan flame ranged between 15 Hz and 18 Hz.
Heat transfer and evaporation of salt solution on a horizontal heating wall
Authors: Misyura Sergey
Published: July 2019

An experimental study of non-isothermal heat transfer and evaporation of thin layers of aqueous solutions of salts has been carried out. Evaporation was realized on a horizontal heated wall in the air atmosphere at a pressure of 1 bar. In the evaporation of water and salt solution, the heat transfer coefficient is constant for a long time period and increases in the final stage due to the multiple reduction of the layer thickness. Evaporation curves for different types of salt solutions have a different character. Due to the increase in salt concentration, the evaporation rate of LiBr-water, CaCl2-water, LiCl-water, and MgCl2-water decreases over time. Salt solutions decreases with time. Evaporation rates for solutions of NaCl-water, CsCl-water, and BaCl2-water slightly change over time. To analyze the effect of free convection on heat transfer, experimental curves for the ratio of Nusselt numbers (A = Nu(salt)/Nu(water)) for the salt and water solution have been built. Parameter A is greater than one and increases with time. The effect of convection on heat transfer varies with time and depends on the current salt concentration and solution layer height, which should be considered in the simulation.

The anthropogenic emission of GHG especially CO has to be limited and reduced due to 2 their impact on global warming and climate change. Combustion of fossil fuels in the energy sector has a dominant share in total GHG emissions. In order to reduce GHG emission, European Union established a scheme for GHG allowance trading within the community, and the implementation of the European Union emission trading scheme, which is a key to GHG reduction in a cost-effective way. An important part of emission trading scheme is prescribed methodology for monitoring, reporting, and verification of the emission of GHG including characterization of the local fuels combusted by the energy sector. This paper presents lignite characteristics from open-pit mine Borovica- Pljevlja, which has highest coal production in Montenegro (>1.2 Mt per year), including evaluation of its carbon emission factor based on the laboratory analysis of 72 coal samples. Testing of the samples included proximate and ultimate analysis, as well as, net calorific value determination. In accordance with the obtained results, linear correlations between net calorific value and combustible matter content, carbon content and combustible matter content, hydrogen content and combustible matter content, carbon content and net calorific value, were established. Finally, the non-linear analytical correlation between carbon emission factor and net calorific value for Pljevlja lignite was proposed, as a base for the precise calculation of CO emission evaluation.
