BORON INCREASES THE VIABILITY OF HUMAN CANCER AND MURINE FIBROBLAST CELLS AFTER LONG TIME OF CRYOPRESERVATION
Authors: HAYAL Taha Bartu
Published: September 2020

Through the process of cryopreservation, cells are stored at very low temperature for a long time to decrease the biological and chemical reactions in viable cells. In this process, the administration of cryoprotective agents is crucial since cryopreservation is regarded as a leading process in various research fields such as biotechnology, clinical medicine and maintenance of both animal and plant cells. Even after a long time of storage in very low temperatures, a recovery is achieved by cryo-preservative agents that act on cellular metabolism and biophysiology of cells. In the current study, the effect of boron on cryopreservation of human lung cancer cell line, A549, and murine fibroblast cell line, L929, was investigated with the help of cell viability assay, colony forming unit assay and RT-PCR analysis. 15 µg/ml boron supplemented freezing medium was found to indicate a positive effect on cell viability. Moreover, gene expression profiles of A549 and L929 cell lines have been altered. The levels of apoptosis related genes decreased while proliferation related gene levels increased significantly after repeated freeze-thaw cycles or long period of freezing. As indicated through our results, sodium pentaborate pentahydrate, as a boron source, might be a crucial cryoprotective agent for cryo-protection and bio-banking of cancer and healthy cells while keeping their viability and functionality.

Published: September 2020

A abordagem Ciência, Tecnologia e Sociedade (CTS) no ensino procura explicitar as inter-relações entre tais elementos e se constitui como importante estratégia para a construção do conhecimento científico juntamente com a formação da consciência cidadã dos sujeitos. Neste artigo, analisam-se aspectos dessa abordagem em dois cursos técnicos em Química, subsequentes ao ensino médio de duas instituições públicas mato-grossenses. Para isso, fez-se análise dos Projetos Pedagógicos de Cursos, tendo como referência a pesquisa documental e elementos da análise de conteúdo para o tratamento analítico, buscando por elementos textuais alusivos à abordagem CTS. A interpretação dos textos dos documentos demonstrou não haver a explicitação da abordagem CTS, prevalecendo a formação técnica. Contudo, é possível identificar no discurso que se extrai de fragmentos dos textos, mensagens que remetem à inquietude da formação técnica em contribuir para que se diminuam os impactos do setor produtivo industrial em questões ambientais e sociais.

Authors: Mariano de Deus Paulo Henrique , Roque Francisco
Published: September 2020

Devido aos problemas ambientais enfrentados pelo bioma Cerrado é urgente aplicar ações voltadas à sua proteção. Nesse sentido, a educação ambiental se mostra como uma excelente abordagem para a conscientização dos efeitos das ações humanas nesse bioma. Neste trabalho, realizado em março de 2018 no Instituto Federal de Brasília (Campus Recanto das Emas), foi avaliada a eficácia de aulas teórica e de campo para abordar os problemas ambientais observados nesse bioma. Nossos resultados sugerem que ambas as aulas foram satisfatórias. Isso porque em ambos os casos houve rendimento similar e aumento do interesse dos discentes pela questão ambiental. Portanto, os dados deste estudo sugerem que reflexões e ações discentes sobre questões ambientais independem da estratégia didática adotada.

Published: September 2020

Esta es una investigación cualitativa de tipo exploratorio, que tiene como objetivo examinar las Representaciones sociales acerca de la adopción en parejas sin hijos y con posibilidades de adoptar, para lo cual se aplicará una entrevista semiestructurada a 50 parejas, además de una ficha de caracterización sociodemográfica elaborada para esta investigación. Se concluye que las parejas tienen una representación sesgada de la adopción, y prejuicios respecto a la edad, la salud, la historia de los niños y niñas, que determinan las resistencias y representaciones respecto a la adopción. Asimismo, las parejas anteponen el proyecto de vida personal, la estabilidad económica, dificultades en los procesos adoptivos, y supuestas preferencias por familias extranjeras, como criterios que dan forma a la resistencia a adoptar, aun cuando identifican que la adopción es un proceso necesario en la sociedad que debe ser fortalecido y asumido por más personas.

Published: September 2020

Aims

The role of the implantable cardioverter defibrillator (ICD) in primary prevention real-world population is debated. We sought to evaluate the incidence, predictors and prognostic impact of ICD shocks in consecutive heart failure patients implanted for primary prevention at our tertiary institution.

Methods and results

We retrospectively selected a sample of 497 patients (mean age 64.8 years, 82.1% men, average left ventricular ejection fraction, LVEF, 27.1%). At long-term follow-up (median time 70.4 months), total mortality was 40.8%, and 16.5% of patients had received at least one appropriate shock (3.12%/year). Inappropriate shock [odds ratio (OR) 1.93, 95% confidence interval (95% CI) 1.08–3.47; P = 0.027] and length of follow-up (1 year, OR 1.01, 95% CI 1.00–1.01; P = 0.0031) were associated with the occurrence of appropriate shock, whereas atrial fibrillation (OR 2.65, 95% CI 1.55–4.51, P < 0.001), length of follow-up (1-year OR 1.01, 95% CI 1.00–1.01, P < 0.001) and appropriate shock (OR 1.93, 95% CI 1.08–3.47, P = 0.027) were associated with the occurrence of inappropriate shock. Neither appropriate nor inappropriate shock independently increased mortality risk, whereas older age (hazard ratio 1.05; 95% CI 1.04–1.07; P < 0.001), atrial fibrillation (hazard ratio 2.25; 95% CI 1.67–3.02; P < 0.001) and lower LVEF (hazard ratio 0.97; 95% CI 0.94–0.99; P = 0.004) did.

Conclusion

Incidence of shocks in real-world primary prevention ICD recipients might be lower than expected, and the association between ICD shocks and prolongation of survival is not as clear-cut as might be perceived. Further investigations from larger real-world samples are warranted.
Sport activity in patients with cardiac implantable electronic devices: evidence and perspectives
Authors: Sciarra Luigi , Salustri Elisa , Petroni Renata , Calò Leonardo , Delise Pietro , Penco Maria , Romano Silvio
Published: September 2020

Demographic characteristics of patients with cardiac implantable electronic devices have significantly changed during the last few years, according to the ageing of the population and the consequent increase in the number of elderly individuals with indication for pacemaker implant and, on the other hand, to the increased number of young individuals implanted with an implantable cardioverter defibrillator for the primary prevention of sudden death. More and more often, both elderly and young patients ask the physician to deal with the device in their daily activities, which often include sport practice. This latter is advisable because of its recognized benefits on cardiovascular prevention, although there are many limitations for patients with a cardiac implantable electronic device. Hence, the need to balance the patient's request with the appropriate precautions emerging from existing evidence.

The current article aims to provide an overview of the most recent data on this topic, derived from registries and observational studies.

Over the years an attempt to standardize recommendations has been made, but robust evidence is still lacking. Substantial differences exist between countries based on their sports regulations. Official recommendations of European and American Scientific Societies are resumed.

The future perspective is to obtain data to allow these patients a safer practice of sport activity also through technological advances in terms of device materials and programming improvement and the possibility of remote monitoring.

Aims

The aim of this study was to report the prevalence, clinical features and outcomes of patients with ST-elevation myocardial infarction (STEMI) hospitalized during the Corona-Virus Disease 2019 (COVID-19) outbreak compared with those admitted in a previous equivalent period.

Methods and results

Eighty-five patients admitted for STEMI at a high-volume Italian centre were included. Patients hospitalized during the COVID-19 outbreak (21 February–10 April 2020) (40%) were compared with those admitted in pre-COVID-19 period (3 January–20 February 2020) (60%). A 43% reduction in STEMI admissions was observed during the COVID-19 outbreak compared with the previous period. Time from symptom onset to first medical contact (FMC) and time from FMC to primary percutaneous coronary intervention (PPCI) were longer in patients admitted during the COVID-19 period compared with before [148 (79–781) versus 130 (30–185) min; P = 0.018, and 75 (59–148)] versus 45 (30–70) min; P < 0.001]. High-sensitive troponin T levels on admission were also higher. In-hospital mortality was 12% in the COVID-19 phase versus 6% in the pre-COVID-19 period. Incidence of the composite end-point, including free-wall rupture, severe left ventricular dysfunction, left ventricular aneurysm, severe mitral regurgitation and pericardial effusion, was higher during the COVID-19 than the pre-COVID-19 period (19.6 versus 41.2%; P = 0.030; odds ratio = 2.87; 95% confidence interval 1.09–7.58).

Conclusion

The COVID-19 pandemic had a significant impact on the STEMI care system reducing hospital admissions and prolonging revascularization time. This translated into a worse patient prognosis due to more STEMI complications.
A cohort study examining urgent and emergency treatment for decompensated severe aortic stenosis
Authors: Ali Noman , Patel Peysh , Wahab Ali , Das Arka , Blackman Daniel J. , Cunnington Michael S. , Malkin Christopher J.
Published: September 2020

Aims

We compared strategies in the treatment of decompensated severe aortic stenosis. The hypothesis was that undertaking urgent or emergency transcatheter aortic valve implantation (TAVI) directly in such patients is safer and more effective than urgent or emergency balloon aortic valvuloplasty (BAV) followed by elective TAVI or surgical aortic valve replacement (SAVR).

Methods

This was a single-centre retrospective study including all consecutive patients who underwent urgent or emergency BAV or TAVI for decompensated severe aortic stenosis between September 2014 and February 2018. Primary endpoints were 30-day and 1-year mortality.

Results

Fifty-two patients underwent urgent or emergency BAV and 87 underwent TAVI. Baseline characteristics of the two groups were well matched. Significant differences were noted between the two groups in 30-day all-cause mortality (88.5% BAV patients alive at 30 days, 97.7% TAVI patients; P < 0.05) and 1-year all-cause mortality (44.2% BAV patients alive at 1 year, 88.5% TAVI patients; P < 0.001). At 1 year, the estimated hazard ratio for patients undergoing BAV was 11.2 (95% confidence interval: 4.67–26.9; P < 0.001) when adjusted for potential confounding variables. Patients in the BAV group who successfully underwent subsequent TAVI or SAVR all survived for 365 days, but there was no significant 1-year mortality difference compared with those who underwent urgent or emergency TAVI (100 vs. 88.5%; P > 0.155).

Conclusion

Our results suggest treatment of decompensated severe aortic stenosis with urgent or emergency TAVI may be associated with improved survival outcomes when compared with a strategy of performing BAV as a bridge to subsequent TAVI or SAVR.
Tuning the Performance of Aqueous Organic Redox Flow Batteries from First Principles
Authors: Yu Junting , Zhao Tianshou , Pan Ding
Published: September 2020

Aqueous organic redox flow batteries have many appealing properties in the application of large-scale energy storage. The large chemical tunability of organic electrolytes shows great potential to improve the performance of flow batteries. Computational studies at the quantum-mechanics level are very useful to guide experiments, but in previous studies explicit water interactions and thermodynamic effects were ignored. Here, we applied the computational electrochemistry method based on ab initio molecular dynamics to calculate redox potentials of quinones and their derivatives. The calculated results are in excellent agreement with experimental data. We mixed side chains to tune their reduction potentials, and found that solvation interactions and entropy effects play a significant role in side-chain engineering. Based on our calculations, we proposed several high-performance negative and positive electrolytes. Our first-principles study paves the way towards the development of large-scale and sustainable electrical energy storage.
Polyvinylidene Difluoride: A Universal Binder for Preparation of Solid Phase Microextraction Devices
Authors: Singh Varoon , Ghosh Chiranjit , Kaur Avneet , Pawliszyn Janusz
Published: September 2020

The communication describes the application of a fluorocarbon-based polymer as a high performance binder component for coatings suitable for a variety of solid phase microextraction (SPME) configurations. SPME devices are characterized by their ability to perform physicochemical extraction of chemical compounds from a given sample, rending said chemical compounds suitable for instrumental determinations; fundamentally speaking, physiochemical extraction is accomplished by thermodynamic equilibrium driven by diffusion and partitioning of chemical compounds. A polyvinylidene difluoride (PVDF) polymer was used to immobilize various sorbent particles on different supports to create different formats of SPME, namely fiber, thin-film membrane, and CBS devices. In this report, PVDF-based coatings are introduced as universal SPME coatings that are amenable to both gas chromatography (GC) and liquid chromatography (LC) while also improving the physical stability of the resulting device, in addition to eliminating the need for highly toxic reagents associated with the preparation of fully fluorinated based coatings previously reported in the literature. Additional incorporation of other polymers to increase coating porosity as well as the adhesion of PVDF on metal surfaces is also described.

Characteristics of Photon Radiation Fields in Iron for Photon Sources with Energies from 10 to 50 MeV
Authors: Smirnov V. V. , Alhagaish I. K. , Sakharov V. K.
Published: September 2020

Based on the results of Monte Carlo calculations of the spatial energy distributions of photons in iron from point isotropic and planar mononirectional monoenergy sources with energies of 10-50 MeV, the air Kerma attenuation multiplicities and dose accumulation factors of the material under consideration are determined.. The calculations take into account the contribution of the fluorescence, annihilation radiation and bremsstrahlung. The independence of the accumulation factors from the angular distribution of the source radiation is shown, and the independence of the attenuation multiplicities from the angular distribution of the source radiation and the weak dependence on its energy in the energy range 30-50 MeV is also shown. The corrections for the barrier protection are determined and their independence from the thickness of the protection and the photon energy of the source is noted. The obtained information allows to reduce the errors of the results of calculations of the thickness of anti-radiation protection of electronic accelerators at high energies, using developed engineering methods of calculation. The obtained information can also be used in calculations of protection against brake radiation of electronic accelerators by engineering methods.

Authors: Nikonov S. P. , Amer D. A.
Published: September 2020

The paper shows the occurrence of pressure waves and their propagation in the equipment of the first circuit of the WWER-1000 reactor plant in emergency situations associated with an instantaneous stop of the Main circulation pump or a two-way flow with an instantaneous two-way break in the cold thread of the main circulation pipeline. The influence of the time of initialization of the accident (pump stop, pipeline rupture) on the intensity of the process-amplitude, frequency of pressure changes is investigated. Pressure drops during an emergency on the main elements of the circuit are considered. It is shown that the maximum changes in the amplitude and frequency of both the pressure and the pressure drops on the circuit elements belong to the initial stage of the accident. The main attention is focused on the pressure drops on the equipment, because this parameter determines the dynamic loads on the equipment, which can lead to its failure.

The paper presents a study of the student interest level at VETI NRNU MEPhI in the development of their own innovative potential. It considers the formal side of youth involvement in the implementation of research projects and the improvement of their own intellectual forces. A sociological survey showed a fairly high level of students' innovative charge noted the difficulties of using an innovative resource, and formulated possible causes of problems of self-realization in this direction. It is found that most of the young people surveyed do not have a steady motivation to reveal their own innovative potential explaining this by increased complexity and laboriousness. The problem of formal and informal employment of students is noted, its causes are revealed. The given data indicate the importance of the development of scientific research skills and confirms the idea that the problem of inefficient use of innovative potential is quite significant, covers a significant part of students and requires further study and system monitoring.

The sphere of ensuring national security is an important object of state policy. When managing this sphere, strategic and tactical levels are distinguished, each of which has its own institutional consolidation. In addition, functional areas of national security, such as nuclear and radiation safety, can be distinguished. The article analyzes the texts of the National Security Strategy of the Russian Federation and the Fundamentals of State Policy in the Field of Nuclear and Radiation Safety of the Russian Federation from the perspective of analyzing the potential of the strategic regulatory impact of these documents. The inconsistency of their texts, the lack of complexity in regulating the institutional framework for the implementation of state policy in the field of national security is noted. It is also shown that there is no correlation between these important documents of strategic management. The study allowed the authors to conclude that strategic documents in the field of ensuring the national security of the Russian Federation require its processing and adjustment.

Authors: Marín-Carangui Luis Bolívar , Torres-Rodas María Augusta
Published: September 2020

Los derechos humanos de las personas con discapacidad, se garantizan expresamente en la Constitución Política del Ecuador, Convenios y Tratados Internacionales y demás legislación interna; a pesar de lo antes expuesto, no se cumple con la protección integral a este grupo de atención prioritaria por parte del Estado, sociedad y familia. Esta situación obedece a la falta o incumplimiento de políticas públicas, con lo que se vulneran los derechos fundamentales en la protección, defensa y exigibilidad, y se afecta la calidad de vida, en especial de personas que tienen algún tipo de discapacidad. La investigación se realizó en coordinación con el Consejo Cantonal de Protección de Derechos del Cantón Azogues, Fundación para el Desarrollo Humano y la Universidad Católica de Cuenca, Sede Azogues. Se parte de la hipótesis que con el conocimiento del ejercicio de los derechos humanos y sociales de las personas con discapacidad y su realidad local, se pueden construir de manera participativa políticas públicas que respondan a la vulneración de derechos con la implementación de planes, programas y proyectos por parte de diferentes instituciones debidamente articuladas, planteándose el objetivo de: “Determinar el cumplimiento de la  garantía de los derechos humanos de las personas con discapacidad del Cantón Azogues de la Provincia del Cañar”. Para el presente estudio se indagó en fuentes secundarias o bibliográficas y técnicas de recolección de datos como la observación, entrevistas y encuestas, con enfoque cualitativo y cuantitativo, en las que se evidencia que existe vulneración de derechos de los grupos de atención prioritaria en las diferentes parroquias del Cantón, y esto obedece a factores sociales, políticos y económicos. No existen mecanismos de control y seguimiento en el cumplimiento de políticas públicas, limitando el ejercicio y cumplimiento de los derechos fundamentales de este grupo de atención prioritario.

Authors: Chukwudi Obi Ifeanyi
Published: September 2020

Plastics are organic materials, which consist of synthetic or natural high-molecular compounds (polymers). Due to the large variety of plastic, its different types have different properties, which make it possible to widely use this material in all fields of industry from packaging to the construction industry. The second highest consumer of organic plastics materials after packaging is the construction industry. Thanks to great versatility, cost effectiveness, durability, strength to weight ratio and low maintenance plastics appear to be economically attractive in the construction sector and are used in the manufacturing of wide range of materials in the construction industry. Plastics most times are not easily seen in buildings, but they are widely used in construction and building industry for a vast and wide range of materials, which include insulation, piping, interior design, piping and conduit (rain water, electrical conduits, and sewage pipes, gas distributions and plumbing). Piping and Conduit for instance can consume around 35% of plastic production and are one of the largest consumers of polymers in construction. The purpose of this research is to study plastic as a construction material that can be used to control the formation of Sick building syndrome in buildings, and also as a material that can often be used in the construction industry.
CROWDING DISTANCE BASED PARTICLE SWARM OPTIMIZATION ALGORITHM FOR SOLVING OPTIMAL REACTIVE POWER DISPATCH PROBLEM
Authors: Lenin K.
Published: September 2020

In this paper, Crowding Distance based Particle Swarm Optimization (CDPSO) algorithm has been proposed to solve the optimal reactive power dispatch problem. Particle Swarm Optimization (PSO) is swarm intelligence-based exploration and optimization algorithm which is used to solve global optimization problems. In PSO, the population is referred as a swarm and the individuals are called particles. Like other evolutionary algorithms, PSO performs searches using a population of individuals that are updated from iteration to iteration. The crowding distance is introduced as the index to judge the distance between the particle and the adjacent particle, and it reflects the congestion degree of no dominated solutions. In the population, the larger the crowding distance, the sparser and more uniform. In the feasible solution space, we uniformly and randomly initialize the particle swarms and select the no dominated solution particles consisting of the elite set. After that by the methods of congestion degree choosing (the congestion degree can make the particles distribution more sparse) and the dynamic e infeasibility dominating the constraints, we remove the no dominated particles in the elite set. Then, the objectives can be approximated. Proposed crowding distance based Particle Swarm Optimization (CDPSO) algorithm has been tested in standard IEEE 30 bus test system and simulation results shows clearly the improved performance of the projected algorithm in reducing the real power loss and static voltage stability margin has been enhanced.

Bu çalışma, yüksek gelirli gelişmekte olan BRICS ve MIST ülkelerinde 1991-2014 yılları için yenilenebilir enerji, yenilenemeyen enerji ve istihdam arasındaki nedensellik ilişkisini Boostrapt Granger Nedensellik analiz ile test etmeyi amaçlamaktadır. Bu nedenle iki model oluşturulmuş; ilk modelde yenilenebilir enerji ve istihdam, ikinci modelde ise yenilenemeyen enerji ve istihdam arasındaki nedensellik ilişkisi tahmin edilmiştir. Elde edilen bulgular değerlendirildiğinde Rusya, Hindistan ve Endonezya’da yenilenebilir enerji ve istihdam arasında çift yönlü nedensellik ilişkisi bulunurken; Güney Afrika, Rusya ve Türkiye’de yenilenebilir enerjiden istihdama doğru bir nedensellik ilişkisi tespit edilmiştir. Çin, Meksika ve Güney Kore’de ise yenilenebilir enerji ve istihdam arasında nedensellik ilişkisi elde edilememiştir. Diğer yandan Hindistan, Çin, Türkiye ve Endonezya’da yenilenemeyen enerji ve istihdam arasında çift yönlü, Brezilya’da ise istihdamdan yenilenemeyen enerjiye doğru tek yönlü nedensellik ilişkisi bulunmuş; Rusya, Güney Afrika, Meksika ve Güney Kore’de ise yenilenemeyen enerji ile istihdam arasında nedensellik ilişkisine rastlanılmamıştır.

Wildlife managers conduct population inventories to monitor species, particularly those at‐risk. Although costly and time consuming, grid‐based DNA hair‐snag sampling has been the standard protocol for grizzly bear inventories in North America, while opportunistic fecal DNA sampling is more commonly used in Europe. Our aim is to determine if low‐cost, low‐effort scat sampling along roads can replace the current standard. We compare two genetic non‐invasive techniques using concurrent sampling within the same grid system and spatially explicit capture–recapture. We found that given our methodology and the present status of fecal genotyping for grizzly bears, scat sampling along roads cannot replace hair sampling to estimate population size in low‐density areas. Hair sampling identified the majority of individual grizzly bears, with a higher success rate of individuals identified from grizzly bear samples (100%) compared to scat sampling (14%). Using scat DNA to supplement hair data did not change population estimates, but it did improve estimate precision. Scat samples had higher success identifying species (98%) compared with hair (80%). Scat sampling detected grizzly bears in grid cells where hair sampling showed non‐detection, with almost twice the number of cells indicating grizzly bear presence. Based on our methods and projected expenses for future implementation, we estimated an approximate 30% cost reduction for sampling scat relative to hair. Our research explores the application of genetic non‐invasive approaches to monitor bear populations. We recommend wildlife managers continue to use hair‐snag sampling as the primary method for DNA inventories, while employing scat sampling as supplemental to increase estimate precision. Scat sampling may better indicate presence of bear species through greater numbers and spatial distribution of detections, if sampling is systematic across the entire area of interest. Our findings speak to the management of other species and regions, and contribute to ongoing advances of monitoring wildlife populations.
Diminutive Functioning in Modern Russian Speech
Authors: Nikolina N. A.
Published: September 2020

The article discusses the features of diminutives in modern Russian speech. The focus is on the use of expressive diminutives, mainly nouns. The main areas of the use of derivatives with suffixes of subjective assessment in Russian speech at the turn of the 21th century are distinguished: unceremonious treatment, communication with children, the gastronomic sphere and consumer service situations. The evaluative ambivalence of expressive diminutives and an increase in the number of contexts involving these derivative words to express irony are stated. A number of trends in the use of expressive diminutives in modern Russian speech are revealed: the use of derivative words, in which the affix semantics contradict the meaning of the stem, and the distribution of status category words and adverbs with diminutive suffixes. The role of diminutives in the Russian language picture of the world and its dynamics associated with changes in the nature of the use of the derivatives in question are emphasized.
Lexicographic Activity of S. I. Ozhegov in 1926–1936. (Leningrad Period)
Authors: Stukova E. G.
Published: September 2020

The article is dedicated to theLeningradperiod of S. I. Ozhegov’s activity (1926–1936), which is insufficiently described in biographical works devoted to the scholar. The period of his post-graduate studies and work at theInstituteofLanguagesand Literature of the West and the East is briefly described. Based on archival materials, interesting facts are presented about the graduate studies of S. I. Ozhegov: the study of Russian participles in the context of the history of the Russian literary language, the development of the question of the first South Slavic influence on the literary language, the work in a research group on compiling Russian dialectology bibliography, and the participation in the compilation of a card index on the article and bibliographic material of the “Russian Philological Bulletin” journal, a joint work with B. A. Larin on the study of vernacular and the city language, etc. The article discusses little known lexicographic projects, on which S. I. Ozhegov worked in 1920–1930s: the vocabulary for “Woe from Wit” by A. S. Griboedov (edited by L. V. Shcherba) and “Draft Dictionary of the Revolutionary Era”. Particular attention is paid to the academic explanatory «Dictionary of the Russian language», edited by N. S. Derzhavin, in which S. I. Ozhegov was the compiler of the issue “D – Dayatelny” (1937). The vocabulary, semantic development of words, illustrative material, etc., of this dictionary are briefly reviewed. Work on this issue was an important stage in the formation of S. I. Ozhegov’s lexicographic experience and presents particular interest, since it was carried out in parallel with the work on the first volume of the “Explanatory Dictionary of the Russian Language” edited by D. N. Ushakov.

Published: September 2020

This study aims to determine the effect of work experience and accountability of internal auditors on the quality of internal audit. Supervision of regional government operations is carried out in stages starting from the Regency / City, Province to the Central level. The independent variables in this study are work experience and accountability. While the dependent variable in this study is the quality of internal audit. it is based on several literature studies and the results of previous studies, the results of this study indicate that work experience and accountability have a very strong role in determining the quality of internal audit, and if someone does the same work repeatedly or continuously, it will be faster and more professional in completing internal audits properly, This is because the auditor has truly understood the techniques or how to properly complete the audit and be careful in completing the audit as expected, therefore the auditor's experience and internal auditor's accountability in carrying out the audit can improve the quality of internal audit.
