Vestibular Function and Motion Sickness Susceptibility: Videonystagmographic Evidence From Oculomotor and Caloric Tests
Authors: Fowler Cynthia G. , Dallapiazza Margaret , Hadsell Kathleen Talbot
Published: April 2020

Purpose

Motion sickness (MS) is a common condition that affects millions of individuals. Although the condition is common and can be debilitating, little research has focused on the vestibular function associated with susceptibility to MS. One causal theory of MS is an asymmetry of vestibular function within or between ears. The purposes of this study, therefore, were (a) to determine if the vestibular system (oculomotor and caloric tests) in videonystagmography (VNG) is associated with susceptibility to MS and (b) to determine if these tests support the theory of an asymmetry between ears associated with MS susceptibility.

Method

VNG was used to measure oculomotor and caloric responses. Fifty young adults were recruited; 50 completed the oculomotor tests, and 31 completed the four caloric irrigations. MS susceptibility was evaluated with the Motion Sickness Susceptibility Questionnaire–Short Form; in this study, percent susceptibility ranged from 0% to 100% in the participants. Participants were divided into three susceptibility groups (Low, Mid, and High). Repeated-measures analyses of variance and pairwise comparisons determined significance among the groups on the VNG test results.

Results

Oculomotor test results revealed no significant differences among the MS susceptibility groups. Caloric stimuli elicited responses that were correlated positively with susceptibility to MS. Slow-phase velocity was slowest in the Low MS group compared to the Mid and High groups. There was no significant asymmetry between ears in any of the groups.

Conclusions

MS susceptibility was significantly and positively correlated with caloric slow-phase velocity. Although asymmetries between ears are purported to be associated with MS, asymmetries were not evident. Susceptibility to MS may contribute to interindividual variability of caloric responses within the normal range.

Published: April 2020

Purpose

Hearing loss, resulting from aminoglycoside ototoxicity, is common among patients with drug-resistant tuberculosis (DR-TB). Those with pre-existing hearing loss are at particular risk of clinically important hearing loss with aminoglycoside-containing treatment than those with normal hearing at baseline. This study aimed to identify factors associated with pre-existing hearing loss among patients being treated for DR-TB in South Africa.

Method

Cross-sectional analysis nested within a cluster-randomized trial data across 10 South African TB hospitals. Patients ≥ 13 years old received clinical and audiological evaluations before DR-TB treatment initiation.

Results

Of 936 patients, average age was 35 years. One hundred forty-two (15%) reported pre-existing auditory symptoms. Of 482 patients tested by audiometry, 290 (60%) had pre-existing hearing loss. The prevalence of pre-existing hearing loss was highest among patients ≥ 50 years (adjusted prevalence ratio [aPrR] for symptoms 5.53, 95% confidence interval (CI) [3.63, 8.42]; aPrR for audiometric hearing loss 1.63, 95% CI [1.31, 2.03] compared to age 13–18 years) and among those with a prior history of second-line TB treatment (aPrR for symptoms 1.73, 95% CI [1.66, 1.80]; PrR for audiometric hearing loss 1.33, 95% CI [1.03, 1.73]). Having HIV with cluster of differentiation 4 cell count < 200 cells/mm

and malnutrition were risk factors but did not reach statistical significance in adjusted analyses.

Conclusion

Pre-existing hearing loss is common among patients presenting for DR-TB treatment in South Africa, and those older than the age of 50 years or who had prior second-line TB treatment history were at highest risk.

Authors: Matthews Jairus-Joaquin , Olszewski Abbie , Petereit Juli
Published: April 2020

Purpose

Little is known about the professional knowledge, training, and attitudes of current and future speech-language pathologists (SLPs) toward serving people who are transgender. The purpose of this study was to understand the current climate of students and professionals in delivering voice and communications services to people who are transgender. An understanding of these areas is necessary to help practicing and aspiring SLPs work toward cultural competence in serving this population.

Method

A survey was completed by 386 speech-language pathology students and SLPs at three professional conferences. The survey assessed the professional and ethical knowledge, training experiences, and attitudes of the participants in relation to communication services for people who are transgender.

Results

In terms of professional knowledge, the majority of students and experienced SLP respondents agreed or strongly agreed (77.8%) that treating clients who are transgender was within the SLP scope of practice and was their ethical responsibility (82.2%). Regarding training, approximately 20% of survey respondents received training for working with people who are transgender, whereas approximately 8% of survey respondents reported having experience working with clients who are transgender. With respect to attitude, approximately 54% of survey respondents reported being comfortable treating clients who are transgender, and 37% of survey respondents reported they were likely to pursue training for treating clients who are transgender. Additional analyses were completed comparing students and experienced SLPs as well as the influence of geographic region.

Discussion

Students and SLPs were generally knowledgeable of professional guidelines and standards regarding serving people who are transgender. However, in this survey, very few clinicians indicated they had received training to serve this population. Recommendations to address this gap are discussed.
The Untapped Potential of Preschool Classroom Volunteers in Language–Literacy Instruction: A Feasibility Study
Authors: Schmitt Jacqueline , Gillispie Matthew
Published: April 2020

Purpose

This pretest–posttest study examined the effects of a professional development training on five volunteer instructors' (VIs) utilization of language and literacy facilitation strategies within interactive shared book readings with low-income preschool children. The training specifically targeted the VIs' use of
wh
-questions, expansions, and references to story grammar elements (SGEs) with use of a corresponding visual aid.

Method

VIs participated in a 3-hr training composed of lecture, video models, role playing, four opportunities to explicitly practice the target strategies, and four opportunities to receive immediate feedback from the investigators. The VIs led storybook readings that were video-recorded for comparison prior to and after the training sessions (two pretraining, two posttraining). The investigators analyzed the VIs' language and literacy strategy usage in the readings. The investigators compared the raw number of
wh
-questions asked, expansions of child responses or comments, the number of references (out of 20) to SGEs, and use of the visual aid pre- and posttraining.

Results

After the training, four of the five VIs increased the number of
wh
-questions asked during readings, and one VI maintained a large number of questions asked, compared to pretraining readings. All VIs provided an increased number of references to SGEs (character, setting, problem, fixing problem, solution) in a variety of capacities (name, definition, book-specific element, visual aid use) to reinforce narrative concepts. VIs had inconsistent increases in expansions of child responses or comments posttraining.

Conclusion

Results revealed the VIs generally increased their facilitation of language and literacy strategies after participating in a professional development training, suggesting utilization of volunteers as instructors may be a valuable area to explore, especially in low-income environments where children may be at risk for language and literacy delays.

Authors: Yildiz Dogan , Karagol Serap
Published: April 2020

In this study, the audio transmission performance of some block coding methods in wavelet and non‐wavelet cases is compared. For this purpose, a communication system has been established in the MATLAB environment for the transmission of the audio signal for 5 s. The comparison of the transmission performance of the block codes was performed separately in different parameters of additive white Gaussian noise, Rician and Rayleigh channels. At the same time, it is determined which discrete wavelet transform (DWT) family is suitable in terms of transmission performance for block coding methods and how DWT level affects transmission performance is investigated. Four DWT families at different levels were applied to the audio signal for linear block coding, Hamming, Cyclic, Bose–Chaudhuri–Hocquenghem, Reed–Solomon, encoded channels, and bit error rate and mean squared error performances were compared.
Faulted terminal open circuit voltage controller for arc suppression in distribution network
Authors: Chen Kunyi , Zhang Wenhai , Xiao Xianyong
Published: April 2020

Existing active arc suppression methods compensate fault current through controlling busbar voltage to zero. However, it may boost the fault point voltage in the case of considering load and feeder impedance, and fail to suppress arc. This study proposes a fault current suppression method by controlling the faulted terminal open‐circuit voltage (FTOCV) and harmonic impedance of neutral‐point. The effect of load and feeder impedance are taken into account. Depending on this, a faulted terminal open‐circuit voltage controller (FTOCVC) is proposed for arc suppression, which consists of a reference voltage calculation module (RVCM) and a reference voltage tracking controller (RVTC). RVTC utilises a dual‐loop voltage control method to adjust the neutral voltage for reducing FTOCV and providing a very low harmonic impedance for neutral‐point. A reference voltage needed by RVTC can be figured out using RVCM accurately considering load impedance and fault distance. Thus, the proposed method can restrain the fault current to almost zero without influence by the load and feeder impedance. Comparison of several arc suppression methods was performed by simulation, and the results indicated the proposed method is more beneficial to extinguish fault arc.

Authors: Vasconcelos Leandro Almeida , Passos Filho João Alberto , de Oliveira Leonardo Willer
Published: April 2020

This study presents a new methodology to determine the optimal Offshore Wind Farms connection point in a power system, with the purpose of maximising the wind power penetration, considering a Benders decomposition approach to represent the security constraints related to the ‘’ contingency criterion. The proposed algorithm uses a mixed‐integer non‐linear programming approach associated with a non‐linear programming, and it is evaluated in a tutorial system (IEEE 14‐Bus) and two networks from the literature: a small case (IEEE RTS‐79), and a medium and real case (Brazilian Birds System). In each case, three points geographically close to each other are selected as candidates in the onshore grid for the wind power injection. The experiments conducted clearly show that the connection decision from the proposed approach led to the maximum safe wind power penetration among the candidate options, which proves its applicability and effectiveness, even for more complex networks, and considering all single transmission line contingencies for safe operation.
Adaptive fault detection in wind turbine via RF and CUSUM
Authors: Xu Qifa , Lu Shixiang , Zhai Zhongping , Jiang Cuixia
Published: April 2020

Rapid developments of wind industry arise the issue of heavy monitoring tasks. The residual monitoring based on normal behaviour modelling is a highly recommended method when fault record information is missing. However, it is difficult to achieve efficient normal behaviour modelling and dynamic residual monitoring simultaneously. To this end, a novel adaptive fault detection scheme, which merges random forest (RF) with adaptive cumulative sum (CUSUM), is proposed. The authors exploit RF to explore the non‐linear mechanism between features and the target variable robustly, and obtain the residuals quickly. Then, they design the adaptive CUSUM control chart of time‐varying shift to sensitively detect the changes of residuals. For illustration, they apply the proposed scheme to the supervisory control and data acquisition data acquired from a wind farm in China. The empirical results demonstrate that the proposed scheme is superior to several competing methods in capturing faults and reducing false alarms. Meanwhile, the authors find it can detect anomaly quickly, automatically and robustly under different signal‐to‐noise ratios. These provide operators sufficient time to adopt an effective maintenance strategy.

The purpose of the study, the materials of which are outlined in this article, is to uncover current trends in the development of environmental monitoring and the tracking of anthropogenic environmental impacts. To achieve this goal, it is proposed to use geoinformation systems to perform environmental monitoring and control, using appropriate software. For this purpose ArcGis software was used which allows monitoring the state of the atmosphere, its pollution and other deviations from the norm. The research was conducted exemplified by nine districts of Kharkiv. As a result of computer geospatial analysis, models and maps of urban pollution have been developed. In general, the intellectual analysis of geostatic models of emission distribution in the city allowed identifying and classifying zones of high concentrations of pollution and comparing them with air quality data. Methods of geostatistics transformed the data from a discrete to a continuous form of representation. Further studies in this area may be related to the improvement of geostatistical data analysis and pollution distribution prediction methods. As an example, mathematical formulas were presented to determine the atmospheric pollution index and the true or predicted pollution index, which can be determined on the basis of the data obtained and represented by elements of the ArcGis software package in a discrete and continuous form.

Published: April 2020

Object of research: to systematize (taking into account the possible consequences to biosphere) the known technologies for ecological restoration of soils contaminated by heavy metals and radionuclides. Only a healing technology should be recognized as one possible methodology for solving any soil problems. For soils contaminated by heavy metals and radionuclides healing patterns is conceptually ordered into the following levels: mission, strategy, technology. The mission of healthy soil should be aimed at maintaining the chemical elements content within the optimum interval. The strategy of healthy soil involves the regulation of individual elements content in the soil. Ex-situ a soil healing technology is implemented outside the original pollution site. In-situ, a soil healing technology is carried out directly on the original pollution site. Excavation of the contaminated soil layer is the first stage for ex-situ soil restoration. In the future it will be possible: 1) storage of contaminated soil at special landfills, 2) treatment of contaminated soil at a special reactor. All technologies for in-situ healthy of heavy metals contaminated soils can be ordered as: 1) localization, 2) deconcentration, 3) inactivation, 4) extraction.

Authors: Alokhina Tetiana
Published: April 2020

The article is focused on the successful implementation of the global goals of restoring water objects in the context of sustainable development that is impossible without solving the regional problems of local watercourses and reservoirs reviving. It is emphasized that awareness of riparian spaces role as ecological corridors and importance of the healthy functioning of the river network through the revitalisation of even minor watercourses leads to growth attention to this problem in an increasing number of countries. On the example of the Slepiotka River in Katowice and Inhulets River in Kryvyi Rih the aspects, on which attention of revitalisation are accented in European countries and in Ukraine, are presented. In European countries, the basis for the approach to river revitalisation is their functioning as integral ecosystems. In Ukraine, nowadays, the main focus of river restoration is on cleaning them from silt sediment. In this article the approaches to decision of river revitalisation questions are presented. The main of them are: enhancing the ecological functionality of the watercourse as an ecosystem; providing flood protection; increasing the residential, cultural and recreational value; securing permanently sustainable use of watercourses and their river valleys.

Published: April 2020

The aim of the research is to choose an effective remote method for surveying the area located above the space mined by underground mining. Often in separate sections of these territories funnels and dips are formed that do not allow the use of methods with finding the performer directly at these potentially dangerous sites. The research methodology is based on the implementation of survey work in the territory of the Ordzhonikidze mine, where underground mining is influencing the state of the ground surface and buildings. In this case, various remote survey methods were used. An analysis of the results of the survey work made it possible to determine the most effective method for studying dangerous areas in which horizontal and vertical deformations are observed. As a result of research, special attention was paid to the use of modern remote sensing methods for the territory of the mine. As a result of the analysis of the survey using remote methods, the expediency of applying the method of terrestrial stereo survey is determined, which has the necessary accuracy, and at the same time it is quite operational. The scientific novelty of the obtained results lies in the fact that the effectiveness of the use of ground-based digital stereo survey for studying the deformations of the ground surface and objects located in the mine and adjacent areas that are undermined by underground mining has been proved. The optimal conditions for performing stereo survey of the ground surface and objects of these territories are determined, and a scheme for performing the binding of survey stations is selected. The practical significance of the research is to study the deformations of the ground surface and buildings on the mine territory and adjacent areas, terrestrial digital stereo survey was used, which made it possible to quickly determine horizontal and vertical deformations for a large number of points with the necessary accuracy.

Authors: Golik Vladimir , Razorenov Yuri , Morkun Vladimir , Morkun Natalia , Tron Vitalii
Published: April 2020

Intensive development of the mining and metallurgical complex results in considerable volumes of waste materials, more than half of which are produced by mining enterprises. Modern mining and processing can provide non-waste production only if mineral extraction and grade recovery from natural and technogenic mineral materials are regarded as a single technological process and the Earth surface preservation becomes a priority in determining parameters of process integration. The research is aimed at improving of the technology of metal leaching in a disintegrator through complex application of metallic ore concentration tailings. A radical step of reducing mining waste hazards is their utilization through introducing technogenic reserves of metallic ore concentration tailings into production, thus creating a new raw material base for the mining industry. Substantiation of the concept of non-waste utilization of off-grade mineral materials depends on the amount of integration of chemical leaching and mechanochemical activation in the disintegrator and is achieved by means of modern information technologies.

Recently, environmental problems have become more acute. In 1980, the International Union for the Conservation of Nature (IUCN) prepared the World Conservation Strategy. This document interpreted the term “sustainable development” as an inseparable link between social development and nature conservation. And already in 1992, after the United Nations Conference on Environment and Development, the concept of sustainable development gained a leading status. The conference materials determined that sustainable development is a development of a society that meets the needs of today without compromising the ability of future generations to meet their own needs. Therefore, being aware of the need for energy conservation, there is increasing emphasis on the use of solar energy throughout the world to generate electricity and heat.

Authors: Krivenko Pavlo , Petropavlovskyi Oleh , Kovalchuk Oleksandr , Rudenko Igor , Konstantynovskyi Oleksandr
Published: April 2020

The paper is devoted to mitigation of steel reinforcement corrosion in alkali-activated slag cement (further, AASC) concretes, based on soluble sodium silicates (further, SSS’s), obtained from high consistensy concrete mixes. Enhancement of AASC fine concretes crack resistance due to modification by complex shrinkage-reducing additives (further, SRA’s) based on surfactants and trisodium phosphate Na3PO .12H2O (further, TSP) was proposed for mitigation of steel reinforcement corrosion. SSS’s were presented by sodium metasilicate (silica modulus 1.0, dry state) and water glass (silica modulus 2.9, density 1400 kg/m3). In case of sodium metasilicate the application of SRA composition “ordinary portland cement clinker – TSP – sodium lignosulphonate – sodium gluconate” provides enhancement of crack resistance starting from early age structure formation with restriction of drying shrinkage from 0,984 to 0,713 mm/m after 80 d. The effect is caused by reduction of water and by higher volume of crystalline hydrates. In turn, SRA presented by compositions “TSP – glycerol” and “TSP – glycerol – polyacrylamide” provide enhancement of AASC fine concretes fracture toughness during late structure formation with increasing ratio of tensile strength in bending to compressive strength up to 37 – 49 % if compare with the reference AASC when water glass is used.

Published: April 2020

The results of experimental studies of the steel fiber influence on the bearing capacity, deformability and crack resistance of reinforced concrete multi-hollow plates are given. We investigated a serial floor slab and a similar one, but with the addition of steel fiber. Both plates are factory-made. For testing, the testing apparatus was designed and manufactured that made it possible to study full-size floor slabs in laboratory conditions. The tests were carried out according to a single-span scheme with the replacing equivalent load. The loading was carried out by applying two concentrated strip vertical loads along the plate width. The load was applied in steps of (0.04 ÷ 0.05) from the breaking load. Each stage ended with exposure lasting up to 10 minutes with fixing all the necessary parameters. Deformations were measured using dial gauges. From the moment the first crack appeared in the stretched zone of concrete, the process of crack formation and opening was monitored. At each level, using the Brunell tube, the width of their opening and height were measured. The moment of cracking in both slabs began at the same relative strain. It has been established that the bearing capacity and crack resistance of a slab of combined reinforcement using steel fiber are respectively 50 and 44% higher than that of a similar reinforced concrete slab. The maximum deflection of the slab of combined reinforcement is 37.5% lower than that of conventional reinforced concrete. The destruction of both slabs occurred under loads, when the relative deformations in the compressed zone of concrete reached 0.80×10-3 and 1.10×10-3 for reinforced concrete and steel-fiber concrete slabs, respectively, the difference is 37.5%.

Published: April 2020

This article reflects on the development of a creative economy training product and toolkit developed by Coventry University with SEBRAE (the Brasilian Micro and Small Business Support Service) and funded by British Council. It was devised following two weeks creative economy scoping visits in autumn 2017 in Brasil. The scoping visits identified the need for a fun and “disruptive” business planning experience leading to rapid prototyping which would allow new creative economy ideas to be brought to market at low development cost – “Sprint”. A one day micro Sprint was tested in four locations in Brazil to excellent feedback in late 2017. The client subsequently requested a three day version of the methodology to invest more time in the cultural change of the creative entrepreneur and the development of an associated toolkit. However, this Sprint has subsequently also been rolled out in a super condensed 3 hour version piloting in 2019 and 2020 in Ukraine through British Council Creative Spark programmes. The toolkit offers skills and techniques to train creative entrepreneurs and their mentors in enabling the growth of the creative economy in their communities. This paper predominantly focuses on the implementation of the client commissioned three day Sprint.

Published: April 2020

In the article, we consider a technique for training university students, who study IT specialties to solve problems of finding ergonomic reserves to improve the efficiency of automated systems. We describe the structure of the “Ergonomics of Automated Systems” course, software for evaluating and optimizing the activities of operators of “human-equipment-environment” systems, and methodological techniques for using ergonomic computer modeling to build effective automated control systems. Discipline is built using a mansystem approach to the study and design of automated systems, when a person is considered the main element of the system, but the diverse influence of hardware, software and information support, as well as the environment, is taken into account. A significant difference between the developed method and similar existing disciplines devoted to the study of the “human factor” is that, firstly, not only the characteristics of the human operator working with technology are studied, but also the mutual influence of system elements; secondly, the course is based on a qualimetric approach to assess the reliability of the activity and the economic results of this activity; thirdly, the computer modeling used is focused on optimization with the use of economic criteria of activity, while observing the requirements of ergonomic norms and standards. Functional networks developed by the scientific school “Efficiency, Reliability, and Quality of Ergotechnical Systems” by Professor Anatoly Ilyich Gubinsky were used as a methodological basis for modeling and optimization of activities.

The idea of the study is that the value potential of the subject is a fundamental element of the knowledge system as part of the realization of the idea of sustainable development in education. The basis of the study used the classification of value categories proposed by Milton Rokeach in 1979. We found that in the main school, the content of the subject “Biology” is primarily aimed at forming ideas about terminal values – “life”, “health”, “nature”; in high school – about terminal values “life”, “health”, as well as instrumental values – “perseverance”. The value ideas of a biology teacher are one of the key factors in the formation of students’ value ideas. In the structure of value representations of biology teachers, the three leaders are orientations towards terminal values. We have put forward the assumption that there is a dissonance between the value ideas of respondents and the values that the school biology course is aimed at forming an idea about.

Productivity and economic growth are key factors to maintain and improve the competitiveness of nations in the global market. The paper analyzes the impact of changes in labour productivity and its effect on the nation’s global competitiveness. The research focuses on the European Union countries and Ukraine that experienced the most severe crisis and afterwards the most rapid recovery in the post-crisis period. At the national level, sufficient productivity dynamics are supported by high levels of market competition, broad investment opportunities, and investment promotion. At the same time, the constant acceleration of the action and volatility of exogenous factors of economic development, qualitative transformations of endogenous factors determine the relevance of constant monitoring of the state of productivity and forecasting it for the medium and long-term periods.
