Authors: Fatemi Farin , Dehdashti Alireza , Jannati Mohammadreza 
Published: June 2022

IntroductionCharacterizing risks associated with laboratory activities in universities may improve health, safety, and environmental management and reduce work-related diseases and accidents. This study aimed to develop and implement a chemical risk assessment method to determine and prioritize more hazardous chemicals in the academic laboratories.MethodsA case-series study was conducted at five academic laboratories and research facilities of an Iranian medical sciences university in 2021. A risk assessment was developed and implemented in three phases to identify, evaluate, and classify potential risks and hazards. The approach provided an innovative tool for evaluating and prioritizing risks in chemical laboratories. Hazards were classified on a five-level scale. The technique reviewed both quantitative and qualitative data and pieces of evidence using Laboratory Safety Guidance (OSHA), Occupational Hazard Datasheet (ILO), the standards of the American Conference of Governmental Industrial Hygienists (ACGIH), International Agency for Research on Cancer (IARC), and National Fire Protection Agency (NFPA) codes.ResultsOverall, the frequency of risks rated from “moderate” to “very high” levels was determined for the health hazards (9.3%), environmental hazards (35.2%), and safety hazards (20.4%). Hydrochloric acid had a high consumption rate in laboratory operations and received the highest risk levels in terms of potential hazards to employees' health and the environment. Nitric acid, Sulfuric acid, Formaldehyde, and Sodium hydroxide were assessed as potential health hazards. Moreover, Ethanol and Sulfuric acid were recognized as safety hazards. We observed adequate security provisions and procedures in academic laboratory operations. However, the lack of awareness concerning health, safety, environmental chemical hazards, and inappropriate sewage disposal systems contributed to the increasing levels of laboratory risk.ConclusionsChemicals used in laboratory activities generate workplace and environmental hazards that must be assessed, managed, and risk mitigated. Developing a method of rating health, safety, and environmental risks related to laboratory chemicals may assist in defining and understanding potential hazards. Our assessment suggested the need for improving the risk perception of individuals involved in handling chemicals to prevent exposure from workplace duties and environmental pollution hazards.
How Are Patented AI, Software and Robot Technologies Related to Wage Changes in the United States?
Authors: Fossen Frank M. , Samaan Daniel , Sorgner Alina 
Published: June 2022

We analyze the relationships of three different types of patented technologies, namely artificial intelligence, software and industrial robots, with individual-level wage changes in the United States from 2011 to 2021. The aim of the study is to investigate if the availability of AI technologies is associated with increases or decreases in individual workers' wages and how this association compares to previous innovations related to software and industrial robots. Our analysis is based on available indicators extracted from the text of patents to measure the exposure of occupations to these three types of technologies. We combine data on individual wages for the United States with the new technology measures and regress individual annual wage changes on these measures controlling for a variety of other factors. Our results indicate that innovations in software and industrial robots are associated with wage decreases, possibly indicating a large displacement effect of these technologies on human labor. On the contrary, for innovations in AI, we find wage increases, which may indicate that productivity effects and effects coming from the creation of new human tasks are larger than displacement effects of AI. AI exposure is associated with positive wage changes in services, whereas exposure to robots is associated with negative wage changes in manufacturing. The relationship of the AI exposure measure with wage increases has become stronger in 2016–2021 in comparison to the 5 years before.JEL Classification: J24, J31, O33.
LDH-TiO2 Composite for Selenocyanate (SeCN−) Photocatalytic Degradation: Characterization, Treatment Efficiency, Reaction Intermediates and Modeling
Authors: Hussaini Minaam , Vohra Muhammad 
Published: June 2022

Selenium as a nutrient has a narrow margin between safe and toxic limits. Hence, wastewater discharges from selenium-containing sources require appropriate treatment that considers health concerns and stringent selenium-related water treatment standards. This work examined the use of a photocatalysis-cum-adsorption system based on a layered double hydroxide coupled with TiO2 (LDH-TiO2) to remove aqueous phase selenocyanate (SeCN−), which is difficult to treat and requires specific treatment procedures. The synthesized LDH and LDH-TiO2 composite samples were characterized using the X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and thermogravimetry analysis (TGA) methods. The XRD results for the uncalcined LDH indicated a hydrotalcite mass with a rhombohedral structure, whereas increasing the calcination temperature indicated transition to an amorphous state. FESEM results for the LDH-TiO2 matrix indicated round titanium dioxide particles and LDH hexagonal layers. The TGA findings for uncalcined LDH showed a gradual decrease in weight up to 250 °C, followed by a short plateau and then a sharp decrease in LDH weight from 320 °C, with a net weight loss around 47%. Based on the characterization and initial selenocyanate adsorption results, the 250 °C calcined LDH-TiO2 matrix was used for the selenocyanate photocatalysis. A ~100% selenium removal was observed using LDH:TiO2 at a 1.5:1 w/w ratio with a 2 g/L dose, whereas up to 80% selenium removal was noted for LDH:TiO2 at a 0.5:1 w/w ratio. The respective difference in the efficiency of selenium treatment was attributed to enhanced LDH-based adsorption sites in the enhanced LDH:TiO2 w/w ratio. Furthermore, the selenite and selenate that occurred during SeCN− photocatalytic degradation (PCD) were also nearly completely removed via adsorption. An optimization exercise using response surface methodology (RSM) for total selenium removal showed R2 values of more than 0.95, with a prediction accuracy of more than 90%. In summary, the present findings show that the use of a photocatalysis-cum-adsorption system based on LDH-TiO2 is a promising technique to treat industrial wastewater discharges for selenocyanate and also remove the resulting intermediates.

Authors: Vapnichnyi S. 
Published: June 2022

The article proposes elements of the methodological system of training students for computer science Olympiads (CSO), which covers four levels: basic, medium, high and advanced. For each of the levels, a list of topics is given; for some topics there are proposed assessment tasks, that can be used to determine the student's readiness. Also for each level the sets of tasks on eolymp.com and codeforces.com are offered. To increase the effectiveness of the proposed approach, it is recommended that students, starting from the medium level, participate in various competitions and Olympiads, which give many motivating impulses to master programming. High and advanced levels include own topics and tasks as well.
Besides, the paper formulates the requirements that were the basis for the selection of tasks by topics and separation of the proposed levels. In particular, there are proposed the following requirements for tasks: availability of interesting plot, making curiosity for students, illustrativeness, connectivity and diversity. The construction of task systems takes into account the didactic and methodological requirements that determine the pedagogical expediency of their use. The model of the process of creating a tasks system, which consists of analytical, design and technological stages, is described.
The proposed approach methodology was successfully used in teaching students of Uzhhorod specialized boarding school with in-depth study of certain subjects (UzhSBSwiDSCS), at summer and winter programming schools in Kremenchug and summer programming schools in Khust. Many students of UzhSBSwiDSCS studied on the basis of this approach, participated in competitions and became winners of various stages of the All-Ukrainian Student Olympiad in Informatics. The mentioned approach has been successfully tested in distance learning.

Published: June 2022

The article deals with possibilities of future foreign language teachers’ language competence formation at the universities of Foreign Languages.
The importance of highly qualified new generation specialists, who are able to adapt quickly to a new polycultural information society, ready for fruitful beneficial cooperation with the representatives of other countries is stressed. Particular attention is paid to Common European Framework of References for Languages, requirements of Bologna Convention and new Ukrainian educational strategies for future teachers’ and philologists’ professional training.
Different approaches to students’ professional training at the university have been analyzed. The advantages of integrated language competence formation as a means of students’ independent general and linguistic horizon’s development and future self-education have been highlighted.
The authors of the article claim that integrated language competence formation enables the learners to move away from learning the same linguistic notions in different subjects, to combine language knowledge in terms of students’ future profession thus showing them the importance and value of it. The peculiarities of the first-year students’ language competence formation are presented.
The necessity of designing an integrated language module as a complex of teaching aids and teaching materials for each topic studied is considered.
The characteristics of the 4 C’s components (content, communication, cognition, culture) of the integrated language module on the topic "Meals" and the integrated skills for each of them are described.
The effectiveness and expediency of integrated language competence formation both for university teachers and students were experimentally proved. The results of interviewing and incomplete tests presented in the article speak about the qualitative growth of students’ language knowledge, habits and skills.
Sustainable Development and Sustainable Science. Where We Came From, Where We Are Now and Where We Are Heading? Part I: The History of the Concept
Authors: Drastichová Magdaléna 
Published: June 2022

This work focuses on the origin, the history and milestones that led to the conceptualization of sustainable development (SD). Not only is the concept of SD broad, but it is often used interchangeably with the more general (but sometimes also more specific) concept of sustainability. The concept of SD is analysed based on its development and relationships with sustainability and related scientific (theoretical) and practical concepts. The rationale behind this work lies in clarifying the meaning of SD, including the concept of sustainability, and, on the basis of this, identifying the main ways of moving closer towards the aims of SD, including quality of life and wellbeing. The limitations of the concept are identified and summarized, as are the alternatives to SD and sustainability. The rationale behind this work lies not only in the clarifying of the SD concept, but also in the normative evaluation of this concept in relation to the wellbeing and quality of life of the Earth’s population for an infinite time period, while maintaining the supply of ecosystem services which the planet provides, taking into account that these resources are not only a source of people’s wellbeing, but are essential for people’s survival in general. Hence this work includes an in-depth sophisticated consideration of the SD concept based on its historical development, with a focus on the most crucial milestones, as well as normative assessments of the concept resulting from this knowledge.

Published: June 2022

The optimal taxation level and tax structure depend on numerous factors and enormously differ from country to country. However, the two mentioned tax policy instruments could ensure economic recovery and sustainable economic growth. This article aims to examine the effects of tax policy on economic development and evaluate the role of appropriate tax instruments in speeding up recovery. The results showed that tax level harms the GDP per capita growth rate in Central Europe and Baltic states over the 2000-2021 period. Another vital finding is the increase in both overall employment and investment to GDP ratio positively affected the real GDP per capita growth rates. In order to foster economic growth government might use tax cuts and other stimuli both for distortionary and non-distortionary taxes. The tax policy’s institutional potential should be improved to neutralize the adverse effects of COVID-19 impact and enhance macroeconomic sustainability.

Authors: Takara Yuya , Ozawa Takahiro , Yamaguchi Masaki 
Published: June 2022

Abstract
Aluminum alloy contains intermetallic compounds, which contribute to the improvement of strength properties. However, when it is exposed a to a corrosive environment, the area around the compounds is dissolved preferentially, resulting in the formation of pitting corrosion. Although this dissolution reaction is presumed to be caused by the potential difference (ΔV) between the matrix and the compounds, it has not been quantitatively clarified how ΔV is generated. In this article, we present our study on the effects of the compound composition on ΔV by using the technique of machine learning. The results showed that ΔV and the elemental concentration of the compounds have a linear relationship.
