Quality management of higher education in the context of digitalization
Authors: Polupan Ksenia Leonidovna
Published: December 2020

This paper discusses the main scientific results of the study associated with the introduction of a new understanding of higher education quality management in pedagogical science related to the digitalization of the educational process at the university. The point is that when a student interacts with other subjects of the educational process, conditions are provided in which the student can realize his or her importance as a subject of the educational process, as a person who models the process of knowing his or her future professional activity, as a future member of the professional community. This allows the student to see the paths of his or her development, to identify key areas in self-organization of activities, in self-development of individual characteristics and personality traits. The implementation of the manage-help scheme, coming to replace the influencing scheme, ensures the participation of the student in building an individual learning path, in the choice of customized forms, methods and technologies of professional training in accordance with individual capabilities, needs and abilities. The research result is the development and scientific justification of the digital quality management system of higher education in the interactive intellectual environment developed by the author. The developed system allows the student to move away from the existing templates and stamps of professional activity, expands his or her opportunities in development (and self-development) and creativity at university.

The paper deals with some questions of specially protected natural areas (SPNA) of the local level. Lake Chernoe (Takovets) is located in Lezhnevo municipal District of the Ivanovo Region and it was founded as a SPNA in 1975, in 2001 it became a SPNA of the local level. The area of the lake is 10,8 hectares, the area of the SPNA is 17 hectares. The paper contains data of a complex ecological study: the lakes parameters, the topography of the banks and soil, the features of its flora, vegetation and fauna. 256 vascular plant species from 5 departments, 6 classes, 62 families and 164 genera were registered by 2019. 13 plant species are rare for the Ivanovo Region flora, among them 3 species (Nuphar pumila , Rubus chamaemorus , Rubus nessensis) are included into the Red Data Book; their populations are briefly characterized. The species composition of mosses is diverse (29 species were noted in total). The fauna is typical of small closed region lakes. The lake is pressed by anthropological factors, its ecosystems are disturbed, it promotes invasive alien plants (there are 28 alien plant species). The lake has a great hydrological, scientific and environment-forming value, it is perspective for ecological tourism planning.

Published: December 2020

The paper deals with the features of substrate and biotopic distribution of fungi species of the Polyporus s.l. genus in the southeast of Western Siberia. Most species have a wide range of substrates represented by various species of woody plants. The most widespread and common species are able to develop a wide range of substrates. Rare species are distinguished by a narrow substrate spectrum. For a rare species P . rhizophilus, adapted to exist in the conditions of subarid regions, found only in steppe biome communities, steppe grasses (Stipa , Festuca) are the only substrate. Most species grow on deciduous wood, only some species can grow on conifers, and only the taiga species P. tubaeformis develops exclusively on conifers in mountainous regions. Fungi substrates are represented by 11 species of angiosperms, 3 species of gymnosperms and steppe grasses. Most species are common in numerous communities; all of them are characterized by a high frequency of occurrence and colonize a wide range of substrates. Biotopically narrowly specialized species are few in number; they are characterized by narrow substrate specialization. In anthropogenic habitats, 6 species out of 14 growing in natural communities were recorded. On the plain territory, 10 species of the genus Polyporus were identified, while 14 species were found in mountain systems, since mountain humid areas contain the largest spectrum of substrates for fungi. The greatest diversity of Polyporus species is recorded in dark coniferous forests, among which the number of species is dominated by black aspen-fir forests. With an increase in aridization and a change in plant communities, rare relict mountain taiga, nemoral and typical taiga species are eliminated. The smallest number of Polyporus species is found in the steppe communities of subarid regions.

Published: December 2020

The primary sources of anthropogenic and technogenic impacts on the environment of urban and suburban areas of the Voronezh and Saratov Regions which are part of the Khopyor River Region have been identified. Among the combined urbanized and man-made sources it is necessary to distinguish the activity of pedestrians and road transport. These conditions characterize the local background of the total anthropo-technological load in relation to the settlements of the research area. Its main manifestations include soil compaction, density of the road and path network and clutter. Arithmetic mean values of degradation impacts were analyzed for settlements in the subregion under consideration. A scale of point-based environmental assessment of the state of the environment is developed for differentiated localities in the Khopyor River Region. High anthropogenic and technogenic load is found in Balashov, middle - in Borisoglebsk, Rtishchevo, low - in Povorino and Gribanovsky, an extremely low load - in Romanovka, Arkadak and Novokhopersk. The obtained and analyzed values of anthropogenic and technogenic loads on the environment demonstrate the features of its state and the direction of its degradation, the levels of environmental comfort of urbanized areas for the population. The system of environmental quality management, urban and suburban environmental management in the Khopyor River Region should be reoriented to an ecosystem basis using the environmental assessment criteria and the environmental monitoring results presented and analyzed in this paper.
The structure and state of coenopopulations of the rare species Hedysarum gmelinii Ledeb. (Fabaceae) in different parts of the range

Published: December 2020

The paper studies the ontogenetic structure features of coenopopulations of a rare representative Hedysarum gmelinii Ledeb. (Fabaceae) on the periphery of the range (the Middle Volga and the Bashkir pre-Urals) and in its central part (the Altai Mountains). The main demographic indicators are determined - the age index and the aging index. Taking demographic indicators into account, the types of coenopopulations were determined according to the delta-omega criterion: in the Bashkir pre-Urals they are mostly young, transitional in the Middle Volga region, and mature in the Altai Mountains. In habitats with great moisture in populations, an increase in the proportion of regenerative individuals was noted. Anthropogenic load (mainly in the form of grazing) has a greater impact on the number and density of individuals, but not on the type of ontogenetic spectrum of coenopopulations. The spatial and ontogenetic structure of coenopopulations of H. gmelinii is characterized by a rather high variety of ontogenetic spectra types (and types of populations, respectively) in the European part of the species range. Differences in the demographic parameters of the populations of the Samara and Orenburg Regions from the populations of the Bashkir pre-Urals and the Altai Mountains were revealed, which is associated with the difference in climatic conditions (primarily the degree of moisture). Features of the organization of H. gmelinii populations indicate their greater instability on the border of the range.
The influence of diatomite rock on humus substances of sod-podsolic soil in conditions of agro ecosystems and physical-chemical mechanism of their interaction
Authors: Kozlov Andrey Vladimirovich , Kulikova Alevtina Khristoforovna , Rumyantsev Ruslan Ivanovich
Published: December 2020

The paper provides an assessment of physical and chemical changes of humus substances in the sludge-colloidal fraction, isolated from the sod-podsolic sandy loamy soil, during its interaction with the diatomite rock of the Inzen deposit in conditions of agro ecosystem of the Nizhny Novgorod Region. The experience was a 3-year (2015-2017) microfield experiment, laid down on one of the fields of Elitkhoz. The diatomite was added to soil once during the summer season of 2014 in doses of 3, 6 and 12 t/ha, on which winter wheat, barley and peas were subsequently grown (varieties are zoned in the Volga-Viatskiy Region). Each year, upon completion of crop cultivation, a silo-colloidal fraction was isolated from selected soil samples by the Kachinsky gravimetric method and analyzed on an IR-Fourier-spectrometer, determining absorption spectra in frequency range of 4000-400 cm-. In soil samples the content of specific organic substance (humus) was also determined by the Thurin method with spectrophotometric termination. The studies revealed that interaction of diatomite with the organic soil matrix resulted in organosilanes RnSiH4-n (930 cm-), organosilanes oxygen-free Si-CH3 (1253 cm-) and oxygen-containing compounds Si-O-CH3 (1110 cm-), as well as siloxane bonds of Si-O-Si (570 cm-). The obtained facts directly indicate formation of silicon-containing organo-mineral complexes in sludge-colloidal fraction and participation of silicon in their formation. It is evident that an active diatomite represented by various silicon acids (HnSiOm) was involved in formation of these bonds. The use of diatomite has helped to maintain content of humus substances in soil at the control level, which can also confirm effects of interaction of silicon substances with organic part and, as a result, prevent its degradation. Based on the obtained results and analysis of scientific literature, a mechanism is proposed for possible physical-chemical interaction of active silicon substances with an organic component of the sludge-colloidal fraction of the sod-podsolic soil, which consists in polymerization of silicon on organo-mineral complexes (bonds -Si-O-Si-), as well as in interaction of the hydrolyzed part of humus substances with silicon with subsequent formation of organosilanes, which are subsequently connected with an organic Si-O-CH3 matrix. Due to the fact that organic matter of soils is involved in the formation of ecological stability of soil cover the established effects make it possible to speak about the increase of agro ecological stability of humus substances in sod-podsolic soil due to the use of diatomite rocks.

Published: December 2020

In this paper the ecological state of recreational areas in Nizhny Novgorod was assessed by the level of soil contamination with heavy metals (HM) and the values of bioindication indicators of the birch (Betula pendula Roth). The objects of the study were 4 recreational areas. The forest park Shelokovsky Farm located far from pollution sources was chosen as a control site. The excess of normative indicators (in multiplicities of normative indicators) on gross content of HM was observed in soils only for nickel: in the park Switzerland in 1,3 times, in Raspberry Ridge - in 2,3 times. The soils with the pollution category moderately dangerous were the most polluted by HM according to the total indicator of pollution: in the protected area Crimson Ridge and in the park Oaks. Bioindication indicators of a birch leaf deviated from the conventional norm in a number of studied areas. The quality of the environment, estimated by fluctuating asymmetry of birch leaves in Shelokovsky Farm and the park Oaks, correspond to 2 points (a slight deviation from the norm), in the Park Switzerland - to 3 points (the average deviation from the norm), and in Crimson Ridge - to 4 points (a significant deviation from the norm). In the two most contaminated sites (Oaks and Crimson Ridge), a decrease of chlorophyll content in birch leaves relative to the control (Shelokovsky Farm) was observed.

Published: December 2020

The paper considers the introduction of alien species of Poaceae Barnhart family into plant communities of South-East Europe salted habitats. In the region only two cosmopolitan alien members of this family - Echinochloa crus-galli (L.) P. Beauv. (archaeophyte of South Asian origin, ksenophyte, epecophyte) and Setaria pumila (Poir.) Roem. et Schult. (archaeophyte of East Asian origin, ksenophyte, epecophyte) - are registered on the specified ecotope type, but very limited both synthaxonomically (number of lower units) and geographically (only in the Lower Volga region - the Volga Delta and the south of Volga-Akhtuba flood-plain). Echinochloa crus-galli invades on saline habitats most actively, in some communities it can be both a constant and a rather abundant species but, most likely, is able to influence significantly the formation of only individual coenoses of a number of associations. Both species are registered in communities of associations distributed on soils of a full range of a salinity degree (both weak- and strongly-salted). Compared to associations on strongly salted soils, they slightly strengthen their positions in these ones with weakly salted soils - both species are registered there more often, and Echinochloa crus-galli is even more plentifully.
The development of medicine as a factor of «epidemic transition» in the urban population of the Middle Volga region
Authors: Rumyantseva Maria Aleksandrovna
Published: December 2020

In the paper the author considers the development of medicine in the twentieth century as a factor that significantly changed the morbidity and mortality of the population of the Middle Volga region. The emergence of penicillin and streptomycin, mass vaccination campaigns and promotion of healthy work and life, vector control and advances in medical science, an increase in the number of doctors and hospital beds per capita and affordable free medical care led to a significant reduction in the number of dangerous epidemics in the country. The urban population of the Middle Volga region faced these processes, too. Cases of polio and malaria, anthrax and tularemia, plague and diphtheria, smallpox and cholera were reduced to a few ones, cases of typhus and dysentery decreased significantly, which inevitably led to a shift in the structure of mortality in the region, exogenous mortality factors gave way to endogenous ones. The shift of morbidity towards neoplasms and cardiovascular diseases was also a trend of the time. And it was the process of epidemic transition that occurred in the second half of the last century, as part of the demographic transition, that determined the current trends in morbidity and mortality of the regions population.

Published: December 2020

The main purpose of higher education is to provide training of highly qualified personnel for all basic directions of socially useful activity in accordance with the needs of society and the state, the needs of the individual in intellectual, cultural and moral development, deepening of knowledge, abilities and skills and their expansion. In modern pedagogy and aesthetics there is an undeniable opinion that in spiritual activities of the individual creating a work of art is a major component of an artistic activity. The foundation of artistic activity is considered to be any object of reality and a substantive or spiritual environment. Creating a work of art its author enjoys social and individual emotional experience, reflecting the reality in the form of artistic images, which consist of art ideas, art assessment and the artistic emotions. Analyzing design activity, we can say that its main purpose is a holistic understanding and design of environmental objects. At the intersection of design with the production of the phenomenon of shape is beyond the scope of art, acquiring great importance in the industrial life of society. In this regard, familiarity with the form and special attention to it is important in the study of artistic and design disciplines in the process of professional training of students majoring in art and design.

Published: December 2020

Respiratory diseases are one of the most pressing problems of modern internal medicine, which is associated with their prevalence, significant impact on the quality of life and social activities of a person. This study is done not only by the complexity of diagnosis and treatment of major respiratory diseases, but also by the rapid development of modern pulmonology. The paper determines the level of knowledge of COPD and community-acquired pneumonia basic concepts among students of 5-6 courses at the Medical Institute of National Research Ogarev Mordovia State University majoring in General medicine with the use of an anonymous questionnaire. The survey was conducted using questionnaires developed on the basis of clinical national recommendations for chronic obstructive pulmonary disease and community-acquired pneumonia. The study found that less than half of senior students do not give correct answers to basic questions about the etiology, pathogenesis, clinical picture or treatment of chronic obstructive pulmonary disease (COPD). More than half of 5-year-students have difficulties answering questions about the etiology, classification, diagnosis, and treatment of community-acquired pneumonia. The results of the survey predispose to additional educational solutions in the field of chronic obstructive pulmonary disease, community-acquired pneumonia and to focus more on prevention and therapy.

Published: December 2020

This paper discusses the problems that inhibit the development of spirituality in the youth, shows the role of educational institutions for young peoples moral stability development, reveals a personal paradigm that initiates self-actualization and improvement of students for socialization in modern Russian society. The paper analyzes the problems of spirituality and intelligence development in Russian universities. It is argued that the presence of spirituality creates a barrier to destructive social phenomena, while intelligence represents the internal and external culture, dignity and morality of the individual. The paper emphasizes that spirituality and intelligence should be protected by the individual from the destructive influence of the criminal environment and dubious offers. Students relying on the theory of reactance must learn to say no. It is noted that according to students the significant components of spirituality are the desire to develop their country, national virtues, the less significant ones are the willingness to sacrifice personal interests for the interests of the fatherland. The role of a comfortable psychological environment in the development of self-education, self-criticism, self-actualization of student youth is shown. It is postulated that an educated person respects other people, recognizes their intrinsic value, originality, meaning and dignity.
On the Relation between Empirical Amplification and Proxies Measured at Swiss and Japanese Stations: Systematic Regression Analysis and Neural Network Prediction of Amplification
Authors: Bergamo Paolo , Hammer Conny , Fäh Donat
Published: December 2020

We address the relation between local amplification and site-condition indicators derived from in situ geophysical surveys for the estimation of the VS profile, and single-station recordings processed with horizontal-to-vertical spectral ratio technique. Site-condition indicators, or proxies (e.g., VS30), aim at “summarizing” the description of the local geophysical structure, with a focus on its relation to site amplification.

The premise for our work was the compilation of two companion databases: one of soil condition proxies and the other of empirically derived Fourier amplification functions, for Swiss and Japanese stations.

We investigated the connection between these two datasets, at first, with a systematic set of regressions correlating each proxy to amplification factors within the frequency band 0.5–20 Hz, second, with a neural network (NN) structure predicting site amplification from proxies.

The regression analyses showed that, generally, site-condition parameters (SCPs) bear a better correlation with amplification within 1.7–6.7 Hz; the “best” indicators are the frequency-dependent quarter-wavelength (QWL) velocity and, among scalar parameters, VS30, the bedrock depth, and f0. Collating Swiss and Japanese datasets, the trend of variation of amplification with respect to most proxies is similar. Finally, we evaluated the prediction performance of various combinations of SCPs, for local amplification, using a NN. To attain a database large enough to constrain the estimation of the network parameters, we merged Swiss and Japanese stations into a single training and validation dataset, motivated by the similarities observed in the regression analyses. The outcome we obtained from the NN is encouraging and consistent with the results of the regressions; SCPs with higher correlation to amplification provide a better forecast of the latter (particularly within 1.7–6.7 Hz). More complete input information, such as QWL parameters (velocity, impedance contrast), or extended ensembles of scalar proxies (particularly, including f0), offer a better estimation of local amplification.
Methodology for Validation of Simulated Ground Motions for Seismic Response Assessment: Application to CyberShake Source-Based Ground Motions
Authors: Fayaz Jawad , Azar Sarah , Dabaghi Mayssa , Zareian Farzin
Published: December 2020

A comprehensive methodology for the validation of simulated ground motions is presented. The suggested methodology can be geared toward any ground-motion simulation method and seismic response assessment, in a target engineering application. The methodology is founded on the comparison between conforming groups of ground-motion waveforms from recordings and simulations and their effect on a representative collection of structures that represent the engineering application. The comparison considers the statistics of earthquake scenarios at the level of the event and site parameters, the resulting waveform characteristics, and the subsequent structural responses. Regression models are developed at three levels (between structural responses and waveform characteristics, structural responses and event and site parameters, and waveform characteristics and event and site parameters). Similarities between the models from groups of recorded and simulated ground motions guide the validation process. The validation methodology is applied to CyberShake (v.15.12) simulations and for the estimation of the column drift ratio of a bridge structure. It is shown that CyberShake (v.15.12) can be used to assess the median seismic response of the used bridge. Some discrepancies between simulations and recordings are observed, which could be attributed to the basin and site-response models used for simulations. Further implementation and refinement of the suggested methodology are recommended to make broader conclusions.
Shallow Shear-Wave Velocity Structure in Oklahoma Based on the Joint Inversion of Ambient Noise Dispersion and TeleseismicP-Wave Receiver Functions
Authors: Tan Jiayan , Langston Charles A. , Ni Sidao
Published: December 2020

Ambient noise cross-correlations, used to obtain fundamental-mode Rayleigh-wave group velocity estimates, and teleseismic P-wave receiver functions are jointly modeled to obtain a 3D shear-wave velocity model for the crust and upper mantle of Oklahoma. Broadband data from 82 stations of EarthScope Transportable Array, the U.S. National Seismic Network, and the Oklahoma Geological Survey are used. The period range for surface-wave ambient noise Green’s functions is from 4.5 to 30.5 s constraining shear-wave velocity to a depth of 50 km. We also compute high-frequency receiver functions at these stations from 214 teleseismic earthquakes to constrain individual 1D velocity models inferred from the surface-wave tomography. Receiver functions reveal Ps conversions from the Moho, intracrustal interfaces, and shallow sedimentary basins. Shallow low-velocity zones in the model correlate with the large sedimentary basins of Oklahoma. The velocity model significantly improves the agreement of synthetic and observed seismograms from the 6 November 2011 Mw 5.7 Prague, Oklahoma earthquake suggesting that it can be used to improve earthquake location and moment tensor inversion of local and regional earthquakes.

El propósito del artículo es analizar la influencia de la reconstrucción de la memoria histórica en comunidades afrodescendientes víctimas del conflicto armado sobre el desarrollo de tejido social, dentro del contexto afrocolombiano Benkos, localizados en la comunidad de Cristo Rey, Santa Marta, Colombia. Se realizó un estudio de corte cualitativo, utilizando la entrevista, observación directa y grupos focales como técnicas de recolección y procesamiento de información, el análisis de contenido como técnica de interpretación de textos y software Atlas Ti para el análisis de los datos. Se trabajó con muestra compuesta por (12) doce familias durante aproximadamente un año calendario. Los resultados evidencian que aun cuando persisten injusticias sociales y falta de reconocimiento de los derechos ciudadanos por parte del Estado, la comunidad afrocolombiana ha encontrado mecanismos sociales de supervivencia en donde realzan y transmiten sus tradiciones, logrando fortalecer así su identidad como cultura creando espacios de intercambio para reconstruir la historia de sus vidas mediante el reconocimiento de su dignidad. Así mismo, muestran ser resilientes a las diferentes coyunturas sociales que enfrentan en su nuevo contexto, llegando a entenderlas y eventualmente iniciar un cambio, esto mediante la gestión de procesos de reparación simbólica y la generación y/o reconocimiento de nuevas estrategias de afrontamiento.
Calidad de vida en el trabajo en empleados reincorporados: Una mirada desde los compañeros de trabajo
Authors: Galarza Iglesias Ana Milena
Published: December 2020

Introducción: La Calidad de vida en el trabajo procura satisfacción del trabajador, considerando la interacción entre aspectos objetivos (empresa) y subjetivos (trabajador). La Reincorporación genera cambios organizacionales a partir de las restricciones laborales.  En este tema poco se ha estudiado desde la mirada que tienen los compañeros del proceso.

Objetivo: Explorar como los compañeros de trabajo perciben la calidad de vida en el trabajo en trabajadores reincorporados.

Métodos: Se realizó un estudio con diseño cualitativo. Se usó la técnica de entrevista en profundidad. Se contó con seis compañeros de trabajo de trabajadores que están en proceso de reincorporación. El análisis se realizó a partir de la lectura y relectura de las entrevistas transcritas realizadas a cada uno de los participantes organizando la información según el esquema que propone Patton con los siguientes aspectos: Experiencia y comportamiento, opinión/valor, sentimientos, conocimiento, sensorial.

Resultados: Desde la perspectiva de los compañeros de trabajo se percibe la calidad de vida en el trabajo y la reincorporación a partir de la afectación en la condición de salud la cual le representa restricciones laborales para trabajar, se percibe como el cumplimiento de los derechos contractuales, sin actividades productivas, que genera desconfianza, con presencia de acoso laboral y en general, que se afecta la calidad de vida del trabajo en el trabajador reincorporado.

Conclusion: Los compañeros de trabajo perciben que las restricciones laborales en la reincorporación laboral afectan la participación en el contexto laboral y por tanto la calidad de vida en el trabajo.
Competitiveness and government spending in Cambodia: An autoregressive distributed lag approach
Authors: Hok Leanghak
Published: December 2020

In the globalization age, global competitiveness is gaining attention from policymakers and scholars. This paper focuses on a measurement of trade competitiveness based upon the expansion of market size. Fiscal policy has become a subject of debate since the global crisis of 2008. This paper attempts to examine the influence of government spending (i.e., government investment and consumption) on trade competitiveness. The Autoregressive Distributed Lags (ARDL) approach is used to estimate the dynamic relationship. The result, based on Cambodia's annual data from 1970 to 2015, shows that Cambodia’s trade competitiveness increases when there is a rise in public investment, government purchases, or aggregate private spending. This study shapes an alternative perception of the effectiveness of fiscal policy as domestic expenditure in enhancing international macroeconomic activities.
The Positive Net Present Value of Loss-making Projects: Economic Content of the Two Internal Rates of Return
Authors: Illés Mária
Published: December 2020

This paper examines the economic content of the positive net present value of a project type that is loss-making and has two internal rates of return. The most important finding is that the economic content of a positive net present value is false in such cases. The financial source of the missing amount to reach the level of business efficiency is a false interest income generated by the method. In such cases, the two internal rates of return are also derived from false interest income. The revealed and mathematically proved causality relationships usually prevail in some form in the case of other types of non-conventional cash flows as well.
Rethinking Classical Precondition Formulas of Changes
Authors: Pataki Béla , Pádár Katalin
Published: December 2020

Some authors have expressed the most important preconditions of change success in different formulas. All formulas but one comprise a threshold value below which change cannot happen. The one without a threshold presumes proportionality between some factors and change success. These two approaches seemingly contradict each other. This paper resolves the contradiction by proposing a new model that comprises both a threshold value and a modified proportional relation that becomes valid beyond the threshold value. The conventional dimension of the ‘result’ is modified from ‘change’ to ‘attitude towards change’ because attitude in itself cannot guarantee that the planned change actually happens.
Digitalization, Quality of Life and Purchasing Power
Authors: Tátrai Márk János , Szabó Roland Z.
Published: December 2020

The World Economic Forum stated that while digitalization caused a rapid productivity growth, it has also had its disadvantages. Can digitalization be the catalyst of economic development? Our hypothesis contributes to the debate that the higher the level of digital development in a given country, the greater the quality of life and purchasing power it can achieve due to the benefits of various digital technologies. In our research, we investigated the relationship between the Digital Economy and Society Index (DESI), the Quality of Life Index (QLI) and the Purchasing Power Index (PPI) among the EU countries from 2014 to 2019. We acquired datasets from Eurostat and Numbeo and examined correlations between indices. We found a strong positive relationship between the level of digitalization, the quality of life, and the purchasing power.

The Manifestation of “The Other” and the Possibility of Self-Redemption - Reconsidering the Authenticity of Where Yellow Sails are Flying
Authors: Ling Zi
Published: December 2020

Authenticity, as a research topic in the field of urban problems, is a concentrated reflection of many cultural anxieties caused by urbanization. This article selects the movie Where Yellow Sails Are Flying, trying to clarify the inherent logic and theoretical contexts of authenticity, including what it is, how to define its perceptual, imaginative and practical connotation in the ontology angle. And then pointing out that “human”, as the core of cognitive schemata in practice, has the meaning of otherness of others, so cannot be attributed to an object of “being” or theoretical reality. It not only contains Benjamin’s Messianic unknowable dimension, but also is closely related to the negation of the metaphysical system of presence in the post-modern context. Finally, authenticity, as a kind of cultural politics and practice, is considered to be a collection of blindness and insight, distorting the experience by generalizing and abstracting while displaying the fracture of the signifier and signified. It is only through multiple cultural perspectives can individuals escape from the history of “the other”. This paper also uses the relevant arguments of scientists or philosophers such as Slavoj Žižek, Zygmunt Bauman and Jacques Lacan to critically interpret the theory of authenticity.

BACKGROUND Diabetes mellitus (DM) is a major cause of avoidable blindness in the developing and the developed countries. Diabetic patients have 25 times more chance of becoming blind than the non-diabetics.1 According to the WHO, the number of people in India affected with Diabetes Mellitus in the year 2000 was 31.7 million which is estimated to rise to 79.4 million by 2030, which would be higher than any other country in the world. 75 percent of all Type 2 diabetics and almost all Type 1 diabetics are expected to develop diabetic retinopathy (DR) over a period of time.2 Diabetic dermopathy or shin spots are the commonest dermatological manifestation in patients with Diabetes Mellitus. It is also known as pigmented pretibial patches, spotted leg syndrome or diabetic dermangiopathy.3 Both diabetic retinopathy and dermopathy are manifestations of diabetic microangiopathy. We wanted to study the association between diabetic retinopathy and diabetic dermopathy. METHODS 182 patients (between 40 - 70 years of age) having diabetes mellitus for at least five years were included in the study and were examined for retinal changes and skin changes. The study period was six months. RESULTS Of the 182 diabetic patients included in this study, 106 (58.2 %) had diabetic retinopathy. Shin spots were seen in 158 cases (86.8 %). 100 (94.3 %) cases with diabetic retinopathy had shin spots. The mean duration of diabetes mellitus in patients with diabetic retinopathy was 11.85 years and it was 8.16 years in those without diabetic retinopathy. The mean duration of diabetes mellitus in patients with shin spots was 14.88 years and it was 10.70 years in those without shin spots. CONCLUSIONS There is significant association between diabetic retinopathy and diabetic dermopathy. KEYWORDS Diabetic Retinopathy, Shin Spots, Diabetic Dermopathy

BACKGROUND Sleep disturbances usually accompany osteoarthritis (OA) because of chronic pain. Poor sleep quality is related to many factors like pain, fatiguability, restless leg syndrome, immobility of joints, anxiety and depression. But the quality of the sleep in patients with osteoarthritis has been rarely studied. We wanted to assess the prevalence of sleep disturbances in OA patients, determine the sleep quality in osteoarthritis patients and evaluate the relationship between pains and sleep quality. METHODS 150 patients with osteoarthritis were selected through convenience sampling as per the inclusion and exclusion criteria. Pittsburgh Sleep Quality Index (PSQI) and Numerical Pain Rating Scale (NPRS) were applied. Data was analysed using SPSS. One sample T test and Pearson Correlation were applied to find the correlation between the pains and sleep quality. RESULTS A total of 86 (57 %) patients with osteoarthritis were found to have sleep disturbances and were assessed for sleep quality and pain level. This group contains 18 (20 %) males and 68 (80 %) females. A total of 62 (72 %) osteoarthritis patients including 14 males and 48 females were having poor sleep quality; 67 (78 %) patients had intolerable pain (NPRS > 7). Strong positive correlation (p-value < 0.001) was found between GPSQI and NPRS. CONCLUSIONS Patients with osteoarthritis with high NPRS values have poor sleep quality. There is significant association between pain and poor sleep quality. It will be highly useful for the patients with osteoarthritis if osteoarthritis treatment protocol includes assessment and management of poor sleep quality. As poor quality is an early indicator of majority of mental illnesses, psychiatric liaison services will be highly beneficial for patients with osteoarthritis.

Background: We investigated the efficacy of esomeprazole for the treatment of gastroesophageal reflux disease (GERD) in a meta-analysis of clinical trials results.
Methods: Medline, Embase, PubMed and Web of Science databases were systematically searched for suitable studies, and double-blind, randomized controlled trials (RCTs) were involved. A meta-analysis of RCTs was performed to analyze the efficacy of esomeprazole on clinical outcomes that associated with the severity of GERD.
Results: A total of 8 clinical trials were selected in our meta-analysis (N=4495, patients with GERD). Esomeprazole treatment yielded a significant improvement in clinical signs and symptoms of GERD compared to placebo group. Funnel plot and Egger test showed there was no significant bias in the publication. Cochrane collaboration tool and Jadad scale were used to indicate that all 8 RCTs were of high quality. The results of Galbraith radial plot showed that no study was the major source of heterogeneity. Esomeprazole treatment significantly decreased the relapse rates more than that of placebo group (RR = 0.729; 95% CI: 0.670 to 0.794; P<0.001). It seems to be lower rates of heartburn (RR = 0.747; 95%CI: 0.665-0.839; P <0.001) and epigastric pain (RR = 0.795; 95%CI: 0.679-0.932; P =0.005) in esomeprazole-treated group compared with the placebo group. Moreover, serious adverse events was less likely to happen after esomeprazole therapy (RR = 1.406, 95% CI: 1.030-1.918; P =0.032).
Conclusion: Compared with the control group, esomeprazole is a promising therapeutic agent that improves the management of patients with GERD.

Background: Repeated research while using the same methodology can be useful and it can enable relevant conclusions in the same health care system. The aim of our study was to perform comparative analysis of the agreement between admission and discharge diagnostic groups in period 2014-2017 with period 2006-2013 in the Clinical Center of Kragujevac, Serbia.
Methods: The 5% simple, random sample was made from the basic set of all hospital reports from Clinical Centre Kragujevac, Serbia, in the period 01.01. 2014 - 31.12. 2017 (n=10228). The first four digits of ICD-10 codes at admission and discharge were compared for agreement. We used discharge diagnosis as a "golden standard". Statistical analysis was performed using Cohen’s Kappa statistic.
Results: In the period 2014-2017, agreement between diagnosis among the most ICD10 groups increased in comparison with the period 2006-2013. Disagreements between diagnosis in the period 2014-2017 in comparation with period 2006-2013 was associated with increased length of stay in the hospital (7.5 vs. 9.1 days, P<0.01), patients were younger (54 vs 49.6 yr, P<0.01), number of males declined (26.3% vs 16.2%, P<0.05), kappa value decreased in XV ICD10 group and XI ICD10 group and kappa value increased in XIV ICD10 group.
Conclusion: Agreement between admission and discharge diagnosis among the most ICD10 diagnostic groups increased. Introduction of a new web application has increased the quality of data, but interpreting it requires the skill of researchers. Further research should identify modifiable causes of discrepancy between admission and discharge diagnoses.
