Authors: Mironov D.V. , Mironov V.M. , Mazanko V.F. , Gertsriken D.S. , Peretyatku P.V.
Published: March 2023

The paper studies the penetration of nitrogen, oxygen, hydrogen, carbon, argon and krypton into copper, nickel, molybdenum, titanium, aluminum, iron and different steels under the action of spark discharges in various media based on radioactive indicators using step-by-step radiometric analysis, macro-, micro-, electron-microscopy and activation autoradiography, Mössbauer and Auger spectroscopy, secondary ion-ionic emission, X-ray diffraction and X-ray microanalysis. The study describes distribution features of penetrating atoms and their concentration profiles. Phase composition of near-surface layers is also determined. It is shown that supersaturated solid solutions of iron in copper and copper in iron are formed during simultaneous iron and oxygen penetration in copper and spinel (Fe6Cu3O4)4. Diffusion of iron and carbon results in supersaturated solid solutions of iron and carbon in copper, copper and carbon in iron, graphite and cementite. Inert gases and nitrogen form solid solutions with copper. Phase composition of near-surface layers in Fe is determined. Iron dioxide FeO, a carbon solid solution in iron with fcc lattice γ-Fe, tetragonal martensite and cementite, two iron (III) hydroxide FeOOH modifications, a supersaturated solid solution of nitrogen and nitride Fe4N, solid solutions of inert gases in iron are formed in the diffusion zone. Simultaneous interaction of molybdenum with iron (the anode material) and various gases results in the formation of substitutional solid solutions of iron in molybdenum and molybdenum in iron, a small amount of interstitial solid solutions of nitrogen and carbon in molybdenum and nitrogen in iron, interstitial phases: molybdenum nitrides and carbides and traces of nitrides of iron (Fe4N, Fe2N) and Fe1,9Mo (λ) phases in the form of needles. Treatment of nickel with a nickel anode in the nitrogen medium promotes formation of a solid solution of nitrogen and nitride Ni3N in the matrix with preserved hexagonal symmetry and lattice parameters that are characteristic of this phase under equilibrium conditions. Atoms of oxygen, nitrogen, carbon and argon are present in the interstitial solid solutions in treatment of nickel in ambient air; however, oxides are not found even on the surface (in the layer ~200 nm). Interaction of titanium with atmospheric gases leads to formation of a solid solution of nitrogen, oxygen, carbon, hydrogen and argon in titanium and titanium nitride Ti2N (ε). Simultaneous saturation of the titanium surface with nickel and nitrogen in the interaction zone causes formation of phases in the following order: nickel nitride; a solid solution of nitrogen and titanium in nickel and a solid solution of both alloying elements in titanium.

With an increase in the amount of renewable, solar photovoltaic in particular, developing efficient energy storage media will become increasingly important. Batteries are one of the most common storage devices, and the maximum runtime and dynamic behavior of batteries play an important role in various energy storage applications. Therefore, it is crucial to understand the battery behavior during charging and discharging operation. This study aims to analyze the properties of a lithium polymer battery to support low-power Solar PV applications through experiment and simulation with a goal of understanding its electrical behavior. A simple experimental test procedure was used to determine the various electric parameters required to develop a model of the battery. Simulations results at various C rates captured the dynamic behavior of the lithium polymer battery, revealing an acceptable trade-off between accuracy and complexity.

Authors: Apreyan R.A. , Atanesyan A.K. , Petrosyan A.M.
Published: March 2023

The physical properties of crystals depend on their chemical composition and their molecular and crystal structure. The presence of donor amino groups (NH2) and acceptor nitro groups (NO2) in a molecule can increase the molecule’s non–linear optical (NLO) properties. L-nitroarginine, in a strong alkaline environment (MOH (M=Li,Na,K), crystallizes to form L-2-nitrimino-1,3-diazepane-4-carboxylic acid (L-NIDCA⋅H2O and L-NIDCA). We found that the slow evaporation of a solution of L-nitroarganine and an alkali in equimolarquantities leads to the formation of a metallic salt with L-2-nitrimino-1,3-diazepane-4-carboxylate anions(K(L-NIDC)⋅H2O, Na(-NIDC), L-NaNIDC, Li(L-NIDC); this salt shows strong NLO properties. This study also addressed the second-harmonic generation of L-KNIDC⋅H2O and L-KNIDC crystals and how their crystal and molecular structure affects the NLO properties. The infrared and Raman spectra of K(L-NIDC)⋅H2O and K(L-NIDC) crystals were studied with respect to these structural features. We found that the intensity of second-harmonic generation in K(L-NIDC) is 2.75 times higher than in the standard KDP crystal, while the intensity in K(L-NIDC)⋅H2O is much lower.

Published: March 2023

A novel hybrid solar-wind reverse-osmosis (RO) multistage flash (MSF) distillation desalination system was manufactured and tested in actual conditions in Iran. Solar energy was used to provide both thermal and electrical power and wind energy was used to provide electrical power. Exergy analysis can be used to design more efficient energy systems by reducing inefficien-cies, and indicates opportunities for improving performance in existing systems. The exergy involved in the hybrid solar-wind RO-MSF desalination system is analyzed below using data obtained from theoretical and experimental studies. The RO and MSF systems, powered by wind and solar energy, achieved increases in the reliability and flexibility of the system and in the quality of the resulting drinking water. According to the exergy analysis, the irreversible losses from the hybrid solar-wind RO-MSF plant are concentrated in the solar collector and the multistage flash chamber. These exergy losses can be reduced by isolating the collector, coating the pipes and MSF walls, selecting the parameters for the vapor compressor and RO membrane and pumps, and improving the flash process. By optimizing the performance of the hybrid solar-wind RO-MSF system, the amount of water recovery should increase, and the energy consumption should decrease, which should improve the overall efficiency of the system.

If the discharge current into a plasma contains direct and variable components, the plasma develops wavelike acoustic instabilities and eventually becomes an acoustoplasmа. Such instabilities lead to bistability, multistability, and hysteresis phenomena of the current–voltage characteristics, causing abrupt changes in the state of the plasma medium. These changes can be imagined as phase transitions and described using catastrophe theory. In the present study, the experimental plasma data are approximated by the equations of catastrophes. After reducing the catastrophe equation to canonical form, the points of possible phase transitions are determined. The phase transition coordinates are then converted to coordinates in the experimental system by inverse transformations. In this way, we determine the points of possible phase transitions in a real experiment. Finally, the parameter changes in an acoustoplasma discharge are obtained by solving incorrectly posed inverse problems. The inverse problem of the experimental data is solved at each current time. Within the neighborhoods of singular points, the incorrectly posed inverse problems are solved by the theory of catastrophes. The proposed methods are applicable to various fields of science and technology.

Introduction: Water, energy, and the environment are three important elements of sustainable development. Production of potable water using desalination technologies powered by renewable energy systems could help solve water scarcity in remote areas with shortages of water or conventional energy sources, or in large cities with air pollution. Hybridization of solar and wind could increase the sustainability and availability of renewable energy sources and reduce energy costs. Additionally, hybridization of reverse osmosis (RO) and MSF could increase efficiency and desalinated water quality and decrease desalinated water cost. Materials and Methods: The research method in this paper is based on modeling, computer simulation, and optimization with MATLAB software, and manufacturing and evaluating the plant at the Tarbiat Modares University Renewable Energy Laboratory. Results: The process of manufacturing the MSF system, solar panel structure, and wind turbine was explained and modeling and optimization results were presented. Testing results of the plant were mentioned, as were the produced power of wind turbine simulated and plant performance evaluated under the environmental conditions of the Tehran region. The rate of fresh water production under changing feed water salinity was evaluated and the real costs of fresh water produced ($/m3) were estimated. At the end of this section, model results and test results were compared. Conclusion: Hybridization of RO and MSF systems with wind and solar energy resources led to increased system reliability and flexibility and higher produced drinking water quality. The desalinated water cost was 1.35 $/m3 in theory and 1.5 $/m3 for actual conditions. Hybridization of wind, solar, RO, and MSF showed proved the best choices to minimize water cost compared to fossil fuel RO or MSF, wind RO, wind MSF, solar RO, solar MSF, or fossil fuel RO-MSF. Hybridization of RO and MSF would result in better economics and operation characteristics than those corresponding to MSF. Water cost can be reduced by 23 to 26% of that of a sole MSF process and the amount of desalinated water produced by the hybrid RO-MSF system is much greater than that of MSF. A comparison of theory outputs and experimental test results showed very good agreement between measured and model data. The test results of the manufactured hybrid solar-wind RO-MSF justified theory results.

The role of neutron beam investigation is significant not only for fundamental science but also for various fields of applied science. This work is dedicated to the formation of neutron beams using the external 18-MeV proton beam of IBA cyclotron C18/18 with a beam current of up to 100 µA. The facility is located at the A. Alikhanyan National Science Laboratory (Yerevan Physics Institute). The possibility to obtain thermal or epithermal neutron beams using the external proton beam of the cyclotron is studied using Geant4 simulations. In this case, a quasimonoenergetic neutron source 9Be (p, n)9B reaction is chosen. As a result of the simulations, the optimal thickness of the 9Be beryllium isotope target is determined. The induced neutron beam is accompanied by a gamma ray background. To decrease the number of accompanying gamma rays, the lead absorber is considered. As a method of separating neutrons from gamma rays, the pulse shape discrimination (PSD) technique is developed. This study shows the possibility of neutron-gamma PSD and its applicability using the EJ-299-33A plastic scintillator.

Published: March 2023

Relevance of research. In order to reduce energy losses, an accurate and timely forecast of the amount of consumed electricity is necessary. Accurate forecasting of electrical loads of industrial enterprises and their divisions (productions, workshops,  departments etc.) allows planning of normal operating conditions, concluding contracts for the electricity supply with the electricity supply company under more favorable conditions, and improving the electricity quality, which ultimately affects the final cost of the products produced by an enterprise. So far, more than 150 forecasting methods of electrical loads have been developed. Usually, the most convenient one is selected based on the forecaster experience by creating and analyzing several forecasting models in order to identify the best. Therefore, in order to simplify the forecasting procedure, it is necessary to develop the methodology for forecasting analysis. This methodology should enable canceling forecasting algorithms that will create lower quality forecasts. The main objective is to develop the methodology for making a forecasting analysis of power consumption on the example of a pumping station of an enterprise with a continuous cycle of work to increase the efficiency of energy consumption and implementation of energy-saving measures. Objects of research: the process of forecasting electrical loads of a pumping station of the enterprise with a continuous cycle of work. Methods of research: fundamental principles of the theory of electrical engineering, statistical methods for power consumption forecasting, the method for detecting the trend of radio signals, and fractal analysis of time series. Research results. The methodology for forecasting analysis of power consumption, which makes it possible to apply the most appropriate methods to forecast the operational power consumption, is developed. For the first time, the radio signal trend detection method is applied to identify the trend of electrical loads. The variation ranges of the fractal parameters of time series of electrical loads are established depending on the variation coefficient of the time series for different periods of time. The Brown method of exponential smoothing that is used to forecast the electrical loads, in the case of identifying the smoothing constant α is in the beyond set ( ), is further improved. The regularity of changes in the fractal parameters of time series of power consumption of a pumping station with an increase in the time series duration and their field of application are explained.

Published: March 2023

Currently, there are practically no automated systems for controlling power flow within the specified limits when the power line is overloaded by active power. Regulation is assigned to the dispatchers of the power system or is carried out by means of emergency automation, which disconnects consumers. Therefore, an urgent task is to expand the arsenal of tools for automatic control of active power flow in overload mode. Relevance. A significant increase in electricity consumers leads to a complication of the electric power system. The workload for dispatching personnel is increasing. Maintaining the smooth operation of the elements of the power system is a very important and responsible task. In modern electric power industry, timely warning and elimination of overloads of network elements are relevant. The study aims are development and research of an intelligent automatic control system for the flow of active power along a power line based on the mathematical apparatus of fuzzy logic. The system is based on the use of the regulating effect of the load. Research methodology. Methods of calculating static load model during their actualization were used. The method of fuzzy sets was used in the construction of an intelligence control system for active power flows in overload condition. The effectiveness was estimated by expert methods. Results. The use of artificial intelligence methods for automatic regulation of transformer voltage under load allows up to 5–7 % reducing the flow of active power in overload mode.

A presente pesquisa se foca nos possíveis museus de imagens passadas, como diria Durand apud Pitta (2017), que se erguem constantemente em interlocuções estabelecidas nas aulas de Arte entre o contexto do audiovisual e as materialidades, sendo aqui escolhidas a figura icônica do Pierrô e do Naruto (Animação). Compondo um campo, uma arquitetura e uma geografia intrinsecamente existenciais. As obras que se criam nas aulas de Arte manifestam a incessante deambulação de imagens advindas de um rico imaginário, em busca de viver na realidade através da fisicalização de memórias consolidadas a partir das experiências significativas dos pequenos, jovens e adultos artistas. Diante disso, objetiva-se por salientar ao leitor a importância da construção de portfólios fotográficos e de olhares sensíveis do Arte/Educador à luz dos estudos de Gilbert Durand e Morin sobre essas atividades, bem como no saber acolher e dialogar com seus contextos em que diariamente os trazem e partilham nas aulas.

“The Moscow Miracle”: a Representation of the “Nineties” in the TV Program “Namedni”
Authors: Volkova Elizaveta , Khlevnyuk Darya
Published: March 2023

The article is devoted to the study of the memory of the 1990s in Russia. The main purpose is to determine the significance of television documentary films, namely the television project “Namedni”, in the process of shaping the memory of Russians about the initial stage of post-Soviet Russia. The episodes of the program “Namedni”, devoted to the period from 1990 to 1999, have been analyzed. The qualitative content analysis of the series was conducted on the basis of the thematic categories: politics, social sphere, economy, culture (sports) and the subject criteria: story title, content, timing, personalities and key details, as well as the organization of the story. The predominantly negative perception of the period of the “nineties” in Russia is not confirmed in the episodes of the program “Namedni”. Political and economic themes predominate in most of the episodes, and the 1990s are presented as an optimistic “era of change”, symbolizing a fleeting transition from the old to a potentially positive and bright new. The ambiguity of the positive image of the 1990s is determined by the low attention of the authors of the program to the events of the regional scale, most of the subjects refer to either global or the capital city events of the past.
The Formation of the Beginning of Dialogue in Anonymous Online Communication
Authors: Kotelnikov Maxim
Published: March 2023

The main purpose of the article is to track and analyze the correlation of technical and semantic aspects of anonymous interaction on the web. The initial phase of communication between two interlocutors in the “Anonymous VKontakte chat” is empirically investigated. Combining the conceptual and methodological resources of conversational analysis and membership categorization analysis, as well as the theory of affordances adapted to technical objects (in this case, anonymous chat), the author defends the concept of the order of statements of anonymous interlocutors for successful interaction. Most visitors use the chat to search for short-term romantic and/or sexual communication, therefore, at the beginning of the correspondence, the interlocutors often seek to identify each other's gender identity using typical statements. The importance of having the first row is noted, since it is he who, with a high degree of probability, gives the priority right to ask a question about the gender identity of the interlocutor. However, this right does not negate the fact that sooner or later (rather sooner) the owner of the first turn will have to answer the questions of the interlocutor, so the anonymous interaction under consideration, through the communicative efforts of actors organized in the next order, tends to information symmetry.

Authors: Pismennaya Elena , Ryazantsev Nikita , Molchanova Natalia
Published: March 2023

The article is devoted to study of the demographic shifts in Japan in the context of their impact on the transformation of migration and foreign educational policy. Some of them were permanent, others arose periodically and were caused by rapid socio-demographic and economic shifts in the Japanese society. The article analyzes the development of the demographic crisis in Japan at the beginning of the 21st century. This period is characterized by ongoing depopulation of the Japanese population, its active aging and unfavorable changes in the labor market caused by the spread of IT technologies and robotization of production. The article analyzes the worsening unfavorable demographic trends, which resulted in a shortage of labor, a decrease in the economic potential of the country, and an increase in the demographic burden on the working population. There have been studied the impact on the demographic processes in Japan of the factor of educational immigration, which is considered as one of the most appropriate resources for compensating for possible demographic losses in the population in the future. Legislative innovations and legal support of external immigration, as well as their practical implementation, have been studied. The results of the activities of the higher school of Japan in teaching foreign citizens and smoothing out the negative dynamics of the demographic situation in the country are presented. Of interest for further research is an in-depth study of the causes and identification of the consequences of the demographic crisis, as well as a substantive analysis of the economic and social effectiveness of changes in Japan's migration policy.
Employment transformation in Russia from the perspective of cross-country comparisons
Authors: Popov Andrei , Soloveva Tatiana
Published: March 2023

The transition of mankind to a post-industrial society marked a profound transformation in various areas of activity. The subject of our attention is employment, which not only has undergone significant changes recently, but is also seriously affected by global challenges. The purpose of the article is to analyze the features and patterns of the employment transformation in Russia on the basis of cross-country comparisons. The chosen research perspective allowed us to observe the situation in the world's leading economies (G7 countries) and identify typical trends for industrialized countries. The paper is based on the data from the International Labor Organization, the Organization for Economic Cooperation and Development, the World Bank, as well as public Internet sources. The analysis clearly demonstrated versatility of the studied phenomenon that we examined within the frames of the sectoral structure and forms of employment, the institutional environment and the development of human capital. In general, the employment transformation in Russia has much in common with that in the G7 countries, which is expressed primarily in redistribution of the labor force to services, spread of non-standard employment, reduction of trade union density rate and adaptation of labor practices to performing works related to solution of cognitive and technological tasks, as well as interpersonal interaction. At the same time, some "delay" is observed in a number of areas, that may be due to the later onset of the changes. In conclusion, we emphasize the importance of finding new opportunities to analyze the various facets of employment transformation and the need to achieve an optimal balance between employment flexibility and decent work.
Scholarly Behavior: Bounded Rational Production of Rational Scientific Knowledge
Authors: Tambovtsev Vitaly
Published: March 2023

People differ greatly in cognitive abilities, but all of them have limited abilities, ranging from the ability to perceive the surrounding reality and ending with the implementation of mathematical calculations and logical conclusions from the premises made. If a fully rational individual not only has complete information about the world, but also unlimited possibilities to make calculations and draw logical conclusions, then real people, including professional researchers, are only bounded rational. However, the scientific knowledge produced by scientists is close to completely rational. The article discusses the components of bounded rationality and those mechanisms within science that allow such a transition to be made. The leading role among these mechanisms belongs to scholarly communication, one of the functions of which is the correction of involuntary and unconscious errors made by bounded rational researchers. It is shown that the execution of this function faces certain difficulties, which are important to investigate in order to improve the error correction process.

The review is referencing the 2-volume publication on the personnel the Siberian Branch of the Academy of Sciences USSR/RAS, published in connection with the 65th anniversary of its creation. There is a comparison with previous similar editions (1982 and 2007). It has been established that the principles for compiling and the main blocks of scientific biographies of scientists – academicians and corresponding members of the Academy of Sciences, formulated in the 2007 edition, have not changed in the 2022 reference book. It is concluded that the publication is value both for historians of science and for specialists in the field of social studies of science (in particular, science scholars and sociologists of science), since the information allows us to draw a number of important conclusions about the sources and specifics of the formation of the upper layer of the academic hierarchy.
Research of pollutant emissions from automotive internal combustion engines in conditions corresponding to the actual use of vehicles
Authors: Andrych-Zalewska Monika
Published: March 2023

The subject of the article is the study of pollutant emissions from automotive combustion engines that operate in conditions corresponding to the actual use of vehicles. Includes information on the properties of exhaust gas parameters characterizing the following features: energy, economic, environmental impact and serviceability, additional and constant. Reference was also made to the possibility of determining driving tests on the basis of the similarity of the frequency characteristics of the speed processes in both driving tests and in the real use of vehicles. The article presents the results of research on pollutant emissions from a passenger car during the RDE test. The emission of carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter and carbon dioxide, as well as the number of particulate matter, were examined. The process of pollutant emission intensity and particle number intensity was presented. Tests were carried out on the statistical properties of the car speed, the intensity of pollutant emissions, and the intensity of the number of particulate matter. Correlation studies were carried out on the speed of the vehicle, the intensity of pollutant emissions, and the intensity of the number of particulate matter.
Local history aspect of pre-revolutionary journalism (on the example of B.P. Knyazhinskiy’s publications)

Published: March 2023

Over time, local history materials do not become obsolete, but, on the contrary, become even more relevant. In this regard, the study of local history topics of the pre-revolutionary press can eliminate white spots in the study of regions. The purpose of the study is to evaluate the contribution of the doctor and publicist B.P. Knyazhinskiy in the development of Tambov local history. We apply the principle of historicism, a systematic approach, the content analysis method of the content. We analyze the historical essay “Ancient Usmansky Assumption Maiden Monastery”. It is noted that the Diocesan Gazette, in which the essay was published, performed an enlightening and educational function in pre-revolutionary Russia within the framework of the mass media system, and the clergy played a progressive function in the regional community. We reveal the local history value of the essay and its research nature associated with the use of documentary and scientific sources of that time. B.P. Knyazhinsky’s publication about the history of the convent in the 17th–18th centuries, revealing aspects of the life of the population of Usman itself, expands the possibilities of using the essay in modern regional historiography. The study results can be used to further study the history of the Tambov region and neighboring territories, as well as to fully describe the media system in the region.
The legacy of Mikhail Viktorovich Panov and a conversation about the present and future of Russian spelling
Authors: Pakhomov Vladimir M.
Published: March 2023

The study is devoted to the life and scientific path of M.V. Panov – an outstanding philologist, teacher, popularizer of the science of language. Particular attention is paid to the scientific interests of M.V. Panov in the field of spelling, his work as deputy chairman of the Spelling Commission in the 1960s, which was preparing a large-scale spelling reform, and activities to popularize spelling, which was associated primarily with the need to explain to society the essence of the changes proposed then. Understanding of M.V. Panov, a speller and educator, is necessary for the further successful work of not only spelling codifiers, but also popularizers of linguistic science. Despite the fact that today it is not supposed to reform the Russian letter and created at the Institute of the Russian Language. V.V. Vinogradov of the Russian Academy of Sciences, a complete academic description of the rules of modern Russian spelling does not imply any changes to the existing rules for writing words, the tasks of linguistic education are not at all outdated. Today, like 60 years ago, native speakers confuse the language itself and writing, pronunciation and spelling, and when commenting on any news related to the language, they demand that “language reforms” be prevented. The legacy of the enlighteners of the past can and should be used by modern popularizers of orthographic science, whose main task today and in the foreseeable future is to prepare the ground for a calm conversation in society about the fate of Russian spelling.
Linguistic features of opposition and antonymy in the field of English-language economic nominations
Authors: Shakiryanov Lev M.
Published: March 2023

The study is devoted to the analysis of the implementation of opposite lexical units of financial orientation, which are in opposition to each other within the framework of simple and complex structures, in which one (contradiction) and two processes (antonymy) of nomination are involved. The theoretical significance of the analysis lies in the generalization of linguistic teachings on the problem of oppositions and antonyms of different years. The purpose of the work is to describe simple structures from the point of view of classifying opposition by part-of-speech and by the method of forming relations, and complex structures from the standpoint of word formation, lexico-semantic means, as well as a combination of both. The objectives of the study are to analyze the grammatical categories of case, animateness/inanimateness and number. Its novelty lies in the fact that, in contrast to the traditional consideration of antonyms as opposites between two or more structures, antonymy is also considered here within one element (opposition), which is understood as nomination. Such general scientific methods as analysis, synthesis, comparison, generalization are applied. To perform particular tasks, the continuous sampling method and the experimental method of logical-semantic classification of opposition and antonyms were used, which allows us to identify two classifications of the first phenomenon within one nomination and three classifications of the second phenomenon within two nominations.
Crise em saúde mental

Published: March 2023

Mesmo com a Reforma Psiquiátrica, o manejo e a intervenção na crise em saúde mental ainda vêm sendo pautados no campo biomédico, carregando as marcas de remanicomialização e da criminalização. São práticas que ainda guardam os traços do controle, do disciplinamento e da repressão, demandando uma ampla discussão desde os aspectos técnicos do manejo até as questões ético-políticas. Por meio de uma revisão teórico-bibliográfica, este trabalho busca identificar os conceitos e expressões de crise em saúde mental, indicando possibilidades analíticas e interventivas para o manejo e a intervenção crítica da/do assistente social.
Investigating Sedentariness and Health Status of Primary School Teachers in Cape Coast Metropolis, Ghana

Published: March 2023

Objective: Physical inactivity is linked to chronic illnesses and disabilities among workers, especially those in high demanding jobs like teachers. Despite the global prominence of sedentary behaviour research, studies drawing the relationships between physical inactivity and multimorbidity among working teacher populations in low-and middle-countries remain untapped. This study assessed the sedentariness and health status of primary school teachers in Cape Coast Metropolis in Ghana.

Method: This cross-sectional survey employed 1109 primary school teachers from the Cape Coast Metropolis in the Central Region of Ghana, using convenient sampling method.

Results: Generally, the teachers were highly sedentary and reported poor health status. Other results showed no difference in sedentariness across gender, t (1107) = -0.32, p > .05. However, female teachers suffer more pain and discomfort, [t (1103.51) = - 3.07, p < .05, anxiety and depression, [t (1099.56) = - 2.85, p < .000,)], and poor health status [t (1107) = 2.14, p < .05, than their male counterparts. Also, pain and discomfort, anxiety and depression, health status and years of work significantly predicted sedentariness among the teachers, F (4, 1104) = 5.966, p=.00, R = .145, R2 = .029, adjusted R2 = .018.

Conclusion: The findings suggest that individualized or personalized interventions are urgently needed to promote regular physical activity to improve the health status and reduce associated complications on the health and well-being, especially among the female primary school teachers. Given the health risks of sedentary lifestyle, behavioral interventions at the person-level (i.e., individualized- routine weekly physical activity programmes) and built environmental restructuring (e.g., creation of walkways to encourage regular walking) could be done to physical activity behavior among teachers within the Cape Coast Metropolis, and perhaps beyond.
