Negotiating the national and transnational in Glen Goei’s films: The Confucian patriarch and the return of the prodigal son
Authors: FitzGerald Carolyn
Published: April 2020

In this article, I analyse the two films directed by Glen Goei, Forever Fever and The Blue Mansion, both of which allegorize Singaporean history via the lens of a family with three children, ruled by a Confucian patriarch. Although Goei is generally not considered a pioneer of Singaporean New Wave film, his works shed light on the emergence of the New Wave in the mid-1990s and a second New Wave, starting around 2005. Whereas the first New Wave was characterized by double mimicry of western and East Asian film in an attempt to critique the Singaporean government and colonialism in Southeast Asia, the second New Wave was driven by a search for local authenticity. In addition, Goei’s films provide insight into tension between the national and transnational in Singaporean film, stemming from the nation’s colonial past, filmmakers’ ambivalent alliance with the People’s Action Party (PAP) and the small size of the local market.
Simulation and reflective experience: An effective teaching strategy to sensitize interior design students to the visual needs of older adults
Authors: Hegde Asha L. , Bishop Nicholas
Published: April 2020

Given global population ageing, there is a pressing need to train students of design using methods that convey the impact of age-related vision impairments on the everyday function of older adults. Design students participated in an experiential study wearing goggles that simulated the prevalent markers of senescence and eye diseases, then completed everyday tasks such as walking down a hall and negotiating visual information. Results reflected the difficulty in detecting objects and signage as experienced by individuals who have visual problems. Students strongly agreed that the simulation experience was valuable and reflective comments on the experience provided insights regarding the perceived difficulty of walking as well as a heightened empathy towards those experiencing age-related eye problems. This study revealed that learning about visual senescence through lectures or cognitive emphasis curriculum could be strengthened by incorporating simulation as a teaching strategy to sensitize design students to the needs of older adults.
Using desirable difficulty concepts to enhance durable learning in design education
Authors: Rutherford Sarah
Published: April 2020

Cognitive psychologists have identified that introducing manageable challenges into the learning environment, coined as ‘desirable difficulties’ by Robert Bjork, helps students retain knowledge more deeply over time. Handling small, workable obstacles in the learning process slows down the learner and can have positive effects on retention and application. The more effort learners must apply to retrieve knowledge for a concept or skill, the more this process of retrieval enriches learning. While there is established literature on desirable difficulty in the field of cognitive psychology, the theory has not been applied to design education. The characteristics of the signature pedagogy of design naturally contain many of the key markers of desirable difficulty that drive learning retention. This article summarizes the major scholarship around the concept of desirable difficulty and explores applications for the teaching and learning of design, specifically around the signature pedagogy elements of critique, the design process and project-based learning.
Art school as a transformative locus for risk in an age of uncertainty
Authors: Gale Cathy
Published: April 2020

Risk is not a neutral term even in (western) contexts of art and design pedagogic practice, where risk-taking is entwined into the matrices of the academy from the macro to the micro: from institution to studio to tutor to student. Neither design education nor practice exist in a vacuum, so the conditions and contingencies of risk in contemporary design pedagogy are unpicked, in relation to place, process and people, as inter-connected (though often fragmented) components of study. Art school is examined as a transformative locus for risk: a conceptual-architectural site for knowledge but also a temporal space of subversion, within which the studio provides students with a relatively safe setting for risk in individual and collective formulations. Neo-liberal policies of standardization and competition are as embedded in educational institutions as they are across all levels of society: the resultant loss of agency is felt individually and collectively. This article reframes risk as fundamentally located and dialogic, an autonomous cooperative and collective action, underpinned by critical thinking and disobedient pedagogies. This is a transformative educational process anticipating change in an expanded mode of design in which the student members of the Alternative Art School are considered as critical agents, employing creative reflexivity as an antidote to the neo-liberal stifling of risk.

The use of cost and time in project decision trees: a model and an application
Authors: Godinho Pedro Cortesão , Costa João Paulo
Published: April 2020

In this paper we present a useful bicriteria model for project analysis based on decision trees, and an application of the model to a production planning problem. We start by presenting a model that allows the use of time and cost in project analysis. This model is easy to use, and it can be applied to a large number of real-life situations when the main objectives are the minimisation of cost and the minimisation of time. The construction of the decision trees for this model may require large computational times, and thus become impracticable. We deal with this problem in two ways: first, we define an algorithm for generating the strategies, and then we introduce an error parameter, which allows us to avoid generating all the strategies that are very close to each other. Finally, we apply the model to a production planning problem. We define the problem, use the algorithm to identify the efficient strategies and analyse the results.
Escaping from poverty through compulsory schooling
Authors: Castro Teixeira Aurora Amélia , Da Costa Vieira Pedro Cosme
Published: April 2020

It is an empirical fact that low-level income countries manufacture low price commodities, using simple technology, with no investment in Research and Development. This constitutes a poverty trap where it is not advantageous for workers to get further training and poorly educated/trained workers are not productive to the R&D sector. We present a model with two sectors, the Commodities sector and the R&D sector, which use labour as input. Applying computation techniques we investigate the impact of compulsory schooling on development. We conclude that the imposition of a minimum level of schooling would make it possible for poorly developed countries to escape from the poverty trap. This result is also relevant for intermediate developed countries such as Portugal where the extension of the existing minimum level of compulsory schooling would permit to overcome the vicious cycle of low-skills-lowinnovation that some industries and regions are stuck.
Reforma económica e convergência
Authors: Pessoa Argentino
Published: April 2020

Por que é tão difícil para tantos países, e parece tão fácil para alguns, alcançar a convergência com os padrões de vida prevalecentes nos países mais avançados? Este artigo procura responder a esta questão, analisando o desempenho de alguns países em desenvolvimento, e o modo como esses países desenvolveram algumas inovações institucionais. A comparação de algumas experiências de crescimento na Ásia com outras da América Latina permitiu-nos retirar alguns factos estilizados e três conclusões principais: a) as reformas bem sucedidas são as que combinam princípios económicos saudáveis com capacidades, restrições e oportunidades locais; b) o crescimento económico não corresponde à ordem natural das coisas e a preparação de um terreno sem obstáculos pode não ser suficiente para estimular o dinamismo da produção; c) as inovações institucionais requerem uma abordagem pragmática que evite o bloqueio ideológico.
Inter-Household private transfers and underlying motives: evidence for Bulgaria
Authors: De Menezes António Gomes , Sciulli Dario
Published: April 2020

The effects of interactions between private transfer behaviour and income redistribution policies depend on the motives underlying private income transfers. This paper tests for two different potential motives: pure altruism versus simple exchange, in the presence of capital market imperfections. Using household survey data for Bulgaria, microeconometric evidence is found that both motives are in effect. We also find evidence that capital market imperfections are likely to be binding for consumption smoothing, and hence are an important cause of private transfers. The results indicate that social security benefits "crowd out" the amount of private transfers received but not the incidence of private transfers. Finally, private transfers play an important role as a safety net as they significantly decrease poverty rates and the inequality of income distribution.
Methods for Combating Unfair Competition in the Intellectual Property Market in Russia and Abroad

Purpose: to reveal the characteristics of unfair competition in the intellectual property market in the Russian Federation and abroad and propose measures to combat such competition.

Main results: Recommendations are presented for improving the methods for combating unfair competition in the intellectual property market. The authors propose methods which can be implemented by means of copyright protection both in the market as a whole and on the Internet, by combating trademark and service mark infringers. Besides, in order to curb unfair competition in the market, possible methods are proposed for changing the registration of domain names that allow protecting rights on the Internet.

Main conclusions: In practice, there is a problem when declaring goods that contain intellectual property items). There is no registry making it possible to search for content, and search using graphic images is also difficult. In order to reduce unfair competition, it is proposed to improve the filling procedure by adding a column indicating the international registry, as well as to create a separate registry with a verbal description of images to facilitate the search. In accordance with this system, it is necessary to improve it regarding errors that are often made when filling out forms. At present, a single mistake can become a reason why the item is not selected. Solving these problems can increase control and effectiveness in terms of intellectual property protection. In most countries, unfair competition is prohibited at the legislative level. However, with the development of economic relations, the methods of unfair competition are continuously improving and becoming more and more subtle and sophisticated.
Age-Related Changes in Synaptic Plasticity Associated with Mossy Fiber Terminal Integration during Adult Neurogenesis
Authors: Murray Karl D. , Liu Xiao-Bo , King Anna N. , Luu Julie D. , Cheng Hwai-Jong
Published: April 2020

Mouse hippocampus retains the capacity for neurogenesis throughout lifetime, but such plasticity decreases with age. Adult hippocampal neurogenesis (AHN) involves the birth, maturation, and synaptic integration of newborn granule cells (GCs) into preexisting hippocampal circuitry. While functional integration onto adult-born GCs has been extensively studied, maturation of efferent projections onto CA3 pyramidal cells is less understood, particularly in aged brain. Here, using combined light and reconstructive electron microscopy (EM), we describe the maturation of mossy fiber bouton (MFB) connectivity with CA3 pyramidal cells in young adult and aged mouse brain. We found mature synaptic contacts of newborn GCs were formed in both young and aged brains. However, the dynamics of their spatiotemporal development and the cellular process by which these cells functionally integrated over time were different. In young brain newborn GCs either formed independent nascent MFB synaptic contacts or replaced preexisting MFBs, but these contacts were pruned over time to a mature state. In aged brain only replacement of preexisting MFBs was observed and new contacts were without evidence of pruning. These data illustrate that functional synaptic integration of AHN occurs in young adult and aged brain, but with distinct dynamics. They suggest elimination of preexisting connectivity is required for the integration of adult-born GCs in aged brain.
Stromal deactivation by CSF1: a new feature of the aggressive pancreatic cancer microenvironment
Authors: Vera Renzo E , Fernandez‐Zapico Martin E
Published: April 2020

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer with one of the poorest prognosis among all malignancies. The initiation and evolution of this kind of tumor depends on a complex interaction between cancer cells and the tumor microenvironment (TME). In an elegant study, Steins et al [1] used a combination of relevant disease models to show that mesenchymal subtype of PDAC shows a distinct deactivation of stellate cells in a CSF1‐dependent fashion. This study shedding light on a new role for the stroma driving an aggressive PDAC subtypes shifts the current paradigm for the requirement of an activated TME to regulate PDAC growth and maintenance.
The role of the androgen receptor as a driver and mitigator of cellular stress
Authors: Doultsinos Dimitrios , Mills Ian
Published: April 2020

Prostate cancer is a high-incidence male cancer, which is dependent on the activity of a nuclear hormone receptor, the androgen receptor (AR). Since the AR is required for both normal prostate gland development and for prostate cancer progression, it is possible that prostate cancer evolves from perturbations in AR-dependent biological processes that sustain specialist glandular functions. The archetypal example of course is the use of prostate specific antigen (PSA), an organ-type specific component of the normal prostate secretome, as a biomarker of prostate cancer. Furthermore, localised prostate cancer is characterised by a low proliferative index and a heterogenous array of somatic mutations aligned to a multifocal disease pattern. We and others have identified a number of biological processes that are AR dependent and represent aberrations in significant glandular processes. Glands are characterised by high rates of metabolic activity including protein synthesis supported by co-dependent processes such as glycosylation, organelle biogenesis and vesicle trafficking. Impairments in anabolic metabolism and in protein folding/processing will inevitably impose proteotoxic and oxidative stress on glandular cells and, in particular, luminal epithelial cells for which secretion is their primary function. As cancer develops there is also significant metabolic dysregulation including impaired negative feedback effects on glycolytic and anabolic activity under conditions of hypoxia and heightened protein synthesis due to dysregulated PI 3-kinase/mTOR activity. In this review we will focus on the components of the AR regulome that support cancer development as well as glandular functions focussing on the unfolded protein response and on regulators of mTOR activity.

Authors: Fomin Kateryna
Published: April 2020

The article substantiates the necessity to study the criterion-content and level structure regarding the formation of readiness of future elementary school teachers to organize dialogic teaching. While creating the program of the experimental work the author has taken into account the basic postulations of psychological and pedagogical science, concerning the problem of the readiness of future specialists to organize dialogic teaching, professionalism of activity and communication and dialogic pedagogical communication. The article offers indicative criteria for studying the readiness of future elementary school teachers to organize dialogic teaching of students: need-motivational, cognitive, social-communicative, reflexive-value and operational-activity, as well as indicators of their detection. The levels of readiness of future elementary school teachers to organize dialogic training are determined - high, medium and low. The author presents the results of the empirical study of the state of students' readiness for dialogic teaching of primary school students according to the need-motivational criterion. The results of diagnostics of future teachers' motivation of achievement, understanding of their motivational structure of dialogic teaching, internal motivation of their readiness for self-development, resistance to external influences (in particular, results of ranking by the degree of importance of motives of future pedagogical professional activity) are presented. It is proved that the introduction into the process of training of primary school teachers of the author’s model allows to change substantially the motivation of future specialists for future professional activity.
Integrated Approach to Learning (On the Example of a Private Institution “School of the Free and Responsive”)
Authors: Pylypiv Olha
Published: April 2020

The current stage of reforming the Ukrainian national school is characterized by a complication of the сontent of education, an increase in the amount of information and a reduction in the time allotted for its learning. Today, the development of education as a system must be realized through systemic knowledge, which is necessary for forming holistic and systemic thinking. This knowledge can be obtained through the integration of the humanities and fundamental disciplines and should be guided by the global level of science development. This approach contributes to the formation of holistic ideas about the world and a human as a whole. These ideas are outlined by the author in the article. The search for ways to improve the education system at school has helped revive the notion of integration of learning, which is gradually being implemented in primary school practice. The purpose of the article is to analyze the main aspects of an integrated approach to teaching at elementary school and to reveal the pedagogical value of thematic days. At the moment, the main task of education in the 21st century is to improve, develop and shape attention, imagination, thinking and memory. However, in general, today's level of the development of education in Ukraine does not give an opportunity to fully fulfill the function of the key resource of the socio-economic development of the country and increase the welfare of citizens. The prestige of education and science in society remains low nowadays. Today, in Ukraine different legislative and regulatory acts provide the implementation of cardinal changes aimed at “a comprehensive development of a person as a personality and the highest value of society, shaping his or her talents, mental and physical abilities, upbringing high moral qualities, forming the citizens capable of a conscious public choice, enrichment on this basis of intellectual, creative, cultural potential of the nation, raising the educational level of the people, providing the national economy with qualified specialists. Ukraine recognizes education as a priority area of socio-economic, spiritual and cultural development of society” [7, p. 65].
Paradigm Space of Modern Higher Education in Ukraine
Authors: Zhelanova Viktoriya
Published: April 2020

The article analyzes the paradigm space of higher education in Ukraine. It is proved that the modern education paradigm has a synthetic character, is based on the polyparadigmality principles and is a synthesis of personally oriented ideas, semantic and cognitive paradigms of education. Their nature and characteristics are considered. The units of analysis selected certain components of the paradigm, namely: mission, goals, objectives, guiding values, content of education, basic didactic tools, teacher-student relationships, criteria, functions. It is proved that the situation of confrontation and contradiction of personally oriented, semantic and cognitive paradigms of education is unacceptable, since each of them has its positives and limitations. It was found that cognitive education provides significant potential for intellectual development of the individual, it is its apparent positive. Proved that the cognitive limitations of education lies in its normative and purely social utility, which not related to the unique personality implementation, which is a passive “object” of teacher pedagogical influence; informative cognitive priority led to its content and disciplinary overload, is a serious problem of modern education in higher education institutions. Proved that priority is individually oriented paradigm associated with the formation of free, individual initiative as the “subject” of his life and this education paradigm is reflexive oriented because its values are leading self-awareness, self-development and personal fulfilment future specialist. However, objective knowledge is sometimes overlooked, and this is a certain difficulty of personally oriented education. It is found out that the benefits of the education semantic paradigm are related to the value-semantic attitude formation towards future professional activity, with updating of personal semantic experience; with semantic choice, with development of future specialist semantic potential. The reflexive nature of the personally oriented, semantic and cognitive paradigms of education is substantiated, and it is proved that the modern paradigm of higher education space will constitute a polyparadigmatic synthesis of their ideas accumulated in the education reflexive paradigm. The polyparadigmality essence is revealed as a research methodology, which is a conceptual synthesis of several existing educational paradigms.
Lectura, escritura y oralidad: la narración colectiva de Colombia en tiempos de posconflicto
Authors: Montejo Vélez Natalia , López Federico
Published: April 2020

Este artículo trata sobre la relevancia de la lectura, la escritura y la oralidad en la Colombia del posconflicto. Para tal fin, tomamos categorías conceptuales como “comunidad letrada”, “lectura crítica” e “imaginación moral”, al igual que reflexiones teóricas y testimoniales sobre las prácticas narrativas en distintos contextos. Asimismo, desde la memoria histórica como concepto, pero a la vez como testimonio, planteamos los posibles desafíos que enfrenta el país al contar la historia de lo sucedido en tantos años de conflicto armado. De esta manera, abordamos varios productos literarios, visuales, cinematográficos y plásticos realizados en el país, que nos permitieron comprender que las prácticas narrativas pueden generar cambios simbólicos y culturales frente a fenómenos como la normalización de la violencia, la corrupción del lenguaje político, la instrumentalización de la democracia y las tensiones inherentes entre memoria y perdón; problemas latentes en los años de confrontación armada pero que ahora aparecen con más claridad en la Colombia del posconflicto.
Population Connectivity Predicts Vulnerability to White-Nose Syndrome in the Chilean Myotis (Myotis chiloensis) - A Genomics Approach

Published: April 2020

Despite its peculiar distribution, the biology of the southernmost bat species in the world, the Chilean myotis (Myotis chiloensis), has garnered little attention so far. The species has a north-south distribution of c. 2800 km, mostly on the eastern side of the Andes mountain range. Use of extended torpor occurs in the southernmost portion of the range, putting the species at risk of bat white-nose syndrome, a fungal disease responsible for massive population declines in North American bats. Here, we examined how geographic distance and topology would be reflected in the population structure of M. chiloensis along the majority of its range using a double digestion RAD-seq method. We sampled 66 individuals across the species range and discovered pronounced isolation-by-distance. Furthermore, and surprisingly, we found higher degrees of heterozygosity in the southernmost populations compared to the north. A coalescence analysis revealed that our populations may still not have reached secondary contact after the Last Glacial Maximum. As for the potential spread of pathogens, such as the fungus causing WNS, connectivity among populations was noticeably low, especially between the southern hibernatory populations in the Magallanes and Tierra del Fuego, and more northerly populations. This suggests the probability of geographic spread of the disease from the north through bat-to-bat contact to susceptible populations is low. The study presents a rare case of defined population structure in a bat species and warrants further research on the underlying factors contributing to this.

Molecular Isomerization in n-Propanol Dimers
Authors: Doroshenko I. , Vaskivskyi Ye. , Chernolevska Ye. , Meyliev L. , Kuyliev B.
Published: April 2020

The molecular isomerization has been studied in n-propanol dimers by quantum-chemical calculations with the DFT method. 25 combinations of molecular pairs are calculated with and without consideration of the dielectric constant of n-propanol. Such approach allowed us to determine the most stable configurations of alcohol dimers. It has been shown that dimers of n-propanol are mostly (77.1%) formed by only 5 of 25 possible configurations at room temperature and by 2 combinations (87.3%) at the melting point. The size distribution of dimers and the spectral dispersion in the region of free and bonded O–H stretching vibrations are calculated.
Aggregation of Molecules in Liquid Ethylene Glycol and Its Manifestation in Experimental Raman Spectra and Non-Empirical Calculations
Authors: Hushvaktov H. , Jumabaev A. , Murodov G. , Absanov A. , Sharifov G.
Published: April 2020

Intra- and intermolecular interactions in liquid ethylene glycol have been studied using the Raman spectroscopy method and non-empirical calculations. The results of non-empirical calculations show that an intermolecular hydrogen bond is formed between the hydrogen atom of the OH group in one ethylene glycol molecule and the oxygen atom in the other molecule. The formation of this bond gives rise to a substantial redistribution of charges between those atoms, which, nevertheless, insignificantly changes the bond length. In the corresponding Raman spectra, the presence of hydrogen bonds between the ethylene glycol molecules manifests itself as the band asymmetry and splitting.
Remote and ground-based observations of land cover restoration after forest reclamation within a brown coal basin
Authors: Masiuk Oleksandr M. , Kharytonov Mykola M. , Stankevich Sergey A.
Published: April 2020

The Semyonovsky - Golovkovsky brown - coal deposit is located within the boundaries of the Dnieper basin geological group and is located in the Alexandria mining region on the watershed of the Ingulets and Beshka rivers. Overburden rocks are loess - like, red - brown and glauconite - containing loams, kaolin and carbonaceous clays quartz, glauconite - containing and carbonaceous sands. The total area of reclaimed land was about 1006 hectares, of which 39 % was used for agriculture, 2 % was pasture and 59 % under forest reclamation. Geomorphologic assessment of the studied area was performed using Sentinel-1 satellite radar interferometry. Multispectral imagery of Sentinel -2 satellite system was used for remote assessment within the study area. We assessed the state of the Robina pseudoacacia plants growing under various forest conditions, in plantations created on the reclaimed landscapes of the Semenovsky - Golovkovsky brown coal basin. The processes of self-regulation and restoration of fertility on the reclaimed lands at the first stages of their biological development were slowed down. This significantly reduced the resistance of phytocenoses, both pure and mixed, to the conditions of the environment to which they were exposed. A comparison of the inventory stem wood of the black locust showed the superiority of monoculture plantations to mixed stands of pine - black locust and maple - black locust. The forest-forming process progresses with age. Remote assessment of the territories was conducted to assess the future prospects of biological conservation of reclaimed lands. The influence of the anthropogenic factor is observed throughout the section and is manifested in the man-made formation of the relief, reshaping of dumps, removal to the surface of overburden rocks. It is established that the height values can vary from 85 m to 213 m. 82.8 % of the surveyed area has not undergone significant changes in relief. About 15.5 % of the territory was under the influence of alluvial - diluvia processes. There have been corresponding changes in the share of vegetation according to vegetation cover fraction (VCF) over the past three years. The highest moisture content at the level of 0.2 - 0.3 relative units in 2015 was recorded in the territory occupying 78.4 % . Meanwhile, the shares of land cover with this level of humidity increased by almost 9% during the following 3 years to 2018. The highest density of vegetative cover was recorded in the North -Western part of the study area of forest reclamation. Thus, considering the potential suitability of the area for forest reclamation, we should note the important role of geomorphological, geological and water resources for the growth and development (formation) of plant communities.

Published: April 2020

The analysis of current scientific work on the use of statistical methods in hydrochemical research has shown that this approach is sufficiently substantial, both in Ukraine and abroad. The purpose of this work is to determine the main statistical parameters and to research the possibility of applying theoretical laws of distribution to the time series of water mineralization.This research presents the results of the application of standard statistical methods of hydrometeorological information processing for data on water mineralization at 28 gauges of the Dnipro basin (within Ukraine) for the period from 1990 to 2015. The dynamics of the obtained statistical parameters (long-term annual average, coefficients of variation, asymmetry and autocorrelation) within the Dnipro basin in Ukraine has been analyzed. The average annual values of mineralization vary substantially within the studied part of the Dnipro basin - in the northern part the maximum value of the annual average mineralization is 447 mg/l, as it moves to the south, the mineralization increases and in the sub-basin of the Middle Dnipro it reaches a maximum of 971 mg/l; the highest values are observed in the south (sub-basin of the Lower Dnipro), where they can reach extremely high values for particular small rivers (the Solon River - Novopavlivka village, 3356 mg / l). The long-term variability of mineralization in the rivers of the studied area is insignificant, and the autocorrelation coefficients of the mineralization series are quite high, in most cases they are significant and tend to decrease from the sub-basin of the Prypyat’ river in the north to the sub-basin of the Lower Dnipro river in the south. Within the framework of the presented research, the possibility of using theoretical distribution curves known in hydrology to describe the series of river mineralization, using the example of the Dnipro basin, has also been analyzed. Using Pearson’s fitting criterion, the Pearson type III distributions and the three-parameter distributions by S.M.Krytsky and M.F.Menkel have been verified on their correspondence with the empirical series of mineralization. As a result, it was found that in 85% of cases the Pearson type III distribution can be used, and the three-parameter by S.M.Krytsky and M.F.Menkel can be used in 60% of cases.
Use of remote sensing data to study ice cover in the Dnipro Reservoirs
Authors: Vyshnevskyi Viktor I. , Shevchuk Serhii A.
Published: April 2020

The information on the use of remote sensing data when studying the ice cover of the Dnipro Reservoirs is given. The main source of data was the images obtained by the satellites Sentinel-2, Landsat, Aqua and Terra. In addition, the observation data from the hydrological and meteorological stations were used. The combination of these data enabled to study the patterns of ice regime in the Dnipro Reservoirs, to specify some features that cannot be determined by regular monitoring. A typical feature of the ice cover of all reservoirs of the Dnipro Cascade, besides the Kyivske one, is the impact of hydropower plants (HPP) located upstream. The runoff of the rivers flowing into the Kyivske Reservoir significantly influences its ice cover. This is especially relates to the period of spring flood. Besides the Dnipro and the Pripyat Rivers, relatively small the Teteriv and the Irpin Rivers flowing from the south-west to the north-east have a rather significant effect on the ice cover of this reservoir. The distribution of ice cover in the Kanivske Reservoir, compared to the Kanivske one, is significantly less. In addition to more southern location and warmer climate, the city of Kyiv also influences the ice cover on it, namely due to the discharge of wastewater from several industrial enterprises, Kyivska TPP-5 and Bortnitska Station of Aeration are ones of them. The impact of Trypilska TPP, which located downstream, is also significant. The longest duration of ice cover in the Kanivske Reservoir is observed in its south-eastern part. A point of interest about the Kremenchuts’ke Reservoir is the fact that the ice cover in it remains for the longest period compared to the other reservoirs. The largest duration of ice cover in this reservoir is observed in the Sulska Bay. The typical feature of the Kamianske Reservoir is the accumulation of ice in its narrow parts. Within the Dniprovske Reservoir, the longest freezing period is observed in the Samara Bay. Besides the operation of hydropower station, the industrial enterprises of Kamianske town and Dnipro city have a great effect on the upper part of this reservoir. There are significant differences in the ice regime of the different parts of the Kakhovske Reservoir, which extends from the north-east to the south-west. The distribution of ice in its shallow north-eastern part is usually much larger than in narrower south-western part.
Study of stability analysis of power system with increasing wind power
Authors: Abdulhamid Mohanad , Benard Koech
Published: April 2020

The use of energy in the world today is increasing with increase in population. The cost and availability of energy significantly impacts our quality of life, the health of national economies and the stability of our environment. The rapid depletion of fossil fuel resources on a worldwide basis has necessitated an urgent search for alternative energy sources to cater to the present day demands. In recent years there has been a significant global commitment to develop clean and alternative sources of energy such as solar and wind. Wind energy technology has been the fastest growing energy source because it is fairly distributed around the world and readily available for use. However, more penetration of wind energy into existing power networks has some impacts on the stability of the power system. Therefore, this paper studies and analyzes the stability of a power system with increasing wind penetration. The paper presents some analyses of a power system and the dynamic behavior which identify the issues that limit the large-scale integration of wind generators in a power system.
An ontology for sharing and managing information in disaster response: An illustrative case study of flood evacuation
Authors: Khantong Sommai , Sharif Mohammad Nazir Ahmad , Mahmood Ahmad Kamil
Published: April 2020

Information management and sharing is an essential ingredient, but a difficult and challenging problem for disaster response management. This paper proposes an ontology as a model to organize and structure information in order to improve the information management and sharing in disaster response management. The ontology was designed and developed based on philosophically grounded foundational ontologies. It was also implemented in ontological languages and demonstrated and evaluated in a case study of the flood evacuation process. This paper also provides a systematic approach to develop a well-founded domain ontology that addresses both static and dynamic aspects of a given domain.
Modeling and simulation of FPGA-based redundant digital systems
Authors: Szász Csaba
Published: April 2020

Reliability is one of the most important criteria that characterize last generation digital systems. In a wide range of applications the required reliability level is achieved by using hardware redundant configurations. Perhaps their most common form is the triple modular redundancy (TMR) based on a majority voting structure. Researchers that use this strategy make a major assumption: in fault-free operation mode the outputs of these digital systems match in all. This paper proves that synchronization and matching in all the outputs of such systems is not such a trivial problem. In this endeavor FPGA-based (Field Programmable Gate Arrays) redundant topologies are considered for study and experiments. Upon these structures specially conceived redundant models have been developed and simulated. The results outline that synchronization of complex digital systems is a difficult engineering undertaking and any initial assumption should be managed with the adequate circumspection.
Positive correlation of psoriasis vulgaris severity and HOMA-IR
Authors: Wardhana Made , Adiguna Made Swastika , Nareswari Putu Ayu Diah
Published: April 2020

Background: Psoriasis vulgaris is a chronic inflammatory skin disease that its aetiology is still not completely known. A chronic inflammation in psoriasis can cause organ dysfunctions. Elevation of proinflammatory cytokines gives rise to insulin resistance by inhibiting insulin and glucose transport mechanism signals. Insulin resistance is the underlying pathogenesis of metabolic syndrome.Objective: This study aimed to undestand any correlation in the severity of psoriasis vulgaris with HOMA-IR.Methods: A cross sectional research involving 35 subjects with psoriasis vulgaris and 15 subjects without who met the selection criteria. HOMA-IR is a formula used to measure insulin resistance which calculates the fasting insulin value in μU/ml x fasting glucose in mg/DL/405 taken from the blood veins of subjects. PASI score was used to determine psoriasis vulgaris severity.Results: This study shows that the HOMA-IR median value was higher in psoriasis subject than the subjects without psoriasis (p<0.05). The correlaton analysis shows a moderate positive correlation between psoriasis vulgaris severity and HOMA-IR (r= 0.427; p<0.05). The prevalence ratio was 8.57, which means psoriasis vulgaris subjects were 8.57 times more likely to have HOMA-IR compared to those without psoriasis vulgaris (p<0.05; 95%CI: 1.26-58.1).Conclusion: This study concludes that there is a moderate positive correlation between severity of psoriasis vulgaris and HOMA-IR values.

Background: Diabetic foot ulcer, one of the chronic complication of diabetes mellitus that has a high morbidity and mortality rate. The primary conventional treatment for diabetic ulcer was debridement, followed by wound treatment as local control to promote healing and epithelization. There are many different methods on wound treatment; however only few types of research compared the efficacy. This study aims to compare the combination of hyaluronic acid and silver sulfadiazine with polyurethane or normal saline in diabetic foot ulcer treatment.Method: A randomized clinical study was conducted to compare the efficacy of silver sulfadiazine with hyaluronic acid, polyurethane and normal saline in Wagner 3 and 4 diabetic foot ulcer as the main treatment until 3 weeks post debridement. Several variables assessed in this study, such as epithelialization area, granulation percentage, and ankle diameters. Appropriate statistical analysis was conducted with SPSS version 17 with p < 0.05 considered significant.Result: The median tissue epithelialization area after 3 weeks of wound treatment on normal saline group was 1.62 cm2 (IQR: 0.2 -2.22), on polyurethane group was 2.79 (IQR: 2.39 -3.19 cm2), and silver sulfadiazine with hyaluronic acid group was 3.1 (IQR: 2.1-4.1) cm2 (p<0.05). There was no significant difference in the percentage of granulation (p=0.136) and ankle circumference (p=0.74) among treatment groups.Conclusion: Silver sulfadiazine with hyaluronic acid promote the wound healing process in Wagner 3 and 4 diabetic foot ulcer after 3 weeks by promoting a better tissue epithelization compared to normal saline and polyurethane.

Background: This study aimed to investigate the role of neutrophil to lymphocyte ratio (NLR) as non-specific and independent laboratory biomarkers when associated with Global Registry of Acute Coronary Events (GRACE) mortality risk score in predicting the morbidity and mortality of patient with acute myocardial infarction (AMI).Methods: A cross-sectional study design among 103 AMI patients who met inclusion criteria were enrolled in this study. NLR was the ratio of absolute count between neutrophil and lymphocyte. In addition, the GRACE score was a valid instrument in evaluating acute coronary syndrome (ACS). Data were analyzed using SPSS software version 17.Results: Correlation test showed a weak positive correlation between NLR value and GRACE risk score (r=0,388; p<0,05). Bivariate comparative analysis showed that there was a significant difference in NLR mean in GRACE score group (F (2,100) =5,215, p=0,007). Using the least significance different, it was found that there was a significant difference of NLR mean between low and high GRACE score group {(p=0,003; 95% CI =-3,556 â€“ (-0,736)}.Conclusion: Our study suggests that there was an increase in NLR value proportional to the higher GRACE stratification risk score and there was a significant difference between NLR values in low and high GRACE groups.

Introduction: Pusher syndrome is a disorder that is clinically present in 5-52% of stroke patients, characterized by active pushing using the non-paretic side towards the paretic side, and resistance to the passive correction of posture. This disorder can pose an unfavorable effect on the rehabilitation of stroke patients. Hence, finding effective therapeutic approaches for pusher syndrome is crucial. This study aimed to identify the existing therapeutic approaches for pusher syndrome and investigate their effectiveness.Methods: A literature review was carried out, where studies were identified through searching the PubMed database from database inception to 2019 using the keywords: â€œpusher syndromeâ€, â€œpusher behaviourâ€, â€œcontraversive pushingâ€, â€œipsilateral pushingâ€, â€œlateropulsionâ€, â€œphysiotherapyâ€, â€œphysical therapyâ€, â€œtreatmentâ€, â€œtherapeutic approachâ€, â€œtherapyâ€ and â€œtrainingâ€. Â The literatures were analyzed systematically based on the results of previous studies.Results: Several approaches were identified for treating pusher syndrome post-stroke, including robot-assisted gait training (RAGT), galvanic vestibular stimulation (GVS), visual feedback (VF), and physiotherapy with additional components such as relaxation therapy in the prone position and lateral stepping with body weightâ€“supported treadmill training (LS-BWSTT). RAGT and VF training appear to be promising adjunctive approaches for treating pusher syndrome. Conventional physiotherapy with additional components such as relaxation therapy and LS-BWSTT have also led to positive effects. However, the effect of GVS has not been established.Conclusion: There is evidence that some therapeutic approaches can be beneficial for improving pusher syndrome and outcomes of stroke patients, in particular when combined with conventional physiotherapy. However, the number of studies is still very limited. Further research with methodological rigor is needed.
