Published: March 2022

Mechanical properties and thermal conductivity of epoxy composites reinforced with recycled clamshell container waste as a micro filler (RCCF) were studied. The studies have been carried out to identify the influence of the two variables, the heating time periods (HT) within the range of 2, 4, 6 min., and wt % within the range of 1 %, 2 %, 4 % of recycled clamshell container waste that has been used as a reinforcing filler of epoxy composites. Recycling polyurethane waste aims to control and maintain a pollution-free environment, which is currently considered a difficult issue in addition to achieving low-cost aspects in preparing the composites. According to the method of no-combustion heating, the clamshell waste was converted from the natural plastic state into solids that were later made into 75 μm micro filler by grinding. Composites were ranked using grey relational analysis (GRA). The effect of each control parameter on response variables was analyzed by the Taguchi method. Using MINITAB 19 software, regression equations were obtained for each variable of mechanical properties and thermal conductivity to predict the properties of epoxy composites. The results of the addition of recycled clamshell container waste to epoxy resin show an improvement in the mechanical properties and thermal conductivity of the composites. The optimal value of the two factors was at HT2wt2, i.e. HT and wt % of 4 min and 2 %, respectively. The optimization values for the bending strength, impact strength, tensile strength, stiffness and thermal conductivity are 68.2 MPa, 10.348 kJ/m2, 21.08 MPa, 80 Shore D and 0.504 W/m·C°, respectively. The proposed Taguchi methodology based on grey relational analysis has been shown to be effective in solving multi-feature decision-making problems.

Due to the widespread use of sensors and sensor networks in the tasks of territory coverage, the relevant criteria are maximizing coverage and minimizing energy consumption. At the same time, the compliance of the network with these criteria is an urgent problem in the modern technological world. A modification of the method for constructing energy-efficient sensor networks is proposed by introducing an additional criterion for minimizing the number of sensors and limiting the number of sensors used, which allows reducing the energy consumption of sensor networks by 19 %. In the resulting optimization problem, the optimality criteria are the functions of minimizing the area of uncovered territory, the value of energy consumption, and the number of sensors. The optimum solution is formed by pairs of values of the coverage radius and the level of intersection of the coverage areas, which provide maximum coverage while minimizing energy consumption and the number of sensors used. To solve the problem, the parameter convolution method and the genetic algorithm were used. In the case of dynamic sensors, the problem is to find such a trajectory of the sensor that provides the maximum flyby of the territory with a minimum length. A grid algorithm is proposed to find the necessary trajectory. The presented algorithm consists in dividing the territory into nodes and estimating the value of the covered territory by the sensor in this node. After the formation of estimates, the search for a Hamiltonian path was used. The case of a multiply connected territory with the possibility of turning it into a simply connected one is considered. A scheme for finding the parameters of energy-efficient coverage of the territory using static and dynamic sensors is proposed.
Development of a systems approach to assessment of investment project risks: risks of unacceptably low project profitability
Authors: Vasiliev Alexander , Vasilieva Nataliia , Tupko Natalia
Published: March 2022

A new systems approach to quantitative estimation of financial risks of investment projects was proposed: an integral risk of the project as a whole for all its parameters at once and the risks for each of its parameters separately. At the same time, the very concept of the project risk has been generalized: instead of the conventional risk of unprofitability, a new, more general concept of the risk of unacceptably low project profitability has been introduced. Two levels of the project profitability were considered: a level acceptable to the investor and a realistically achievable level. Corresponding values of design parameters and indices of financial efficiency of the project were found for these levels. Based on the found values, relative margins of investment acceptability and risks of unacceptably low profitability of the project were calculated. A procedure of comprehensive assessment of the risk of unacceptable low profitability of the project for cases of high certainty and partial uncertainty has been developed. Explicit formulas for quantitative risk assessment of unacceptably low profitability of the project have been derived, ranges of values of all risks under consideration have been determined and appropriate recommendations have been given. Explicit formulas for calculating the values of project risks and dynamic points of project acceptability are convenient and useful for software implementation (for example, within the Monte Carlo method). For the Monte Carlo method and the method of scenarios, another alternative approach to assessing the integral risk of unacceptably low project profitability was proposed by the authors based on the direct calculation of unacceptable scenario values of any criterion of the project financial efficiency. A new index of financial efficiency of the project has also been introduced: a discounted period of acceptable return (discounted payback period of the project is its special case).

Published: March 2022

Ensuring the reliable operation of the dust fuel preparation system at thermal power plants (TPP) is a topical issue since it determines the energy strategy of any country that fires coals for thermal energy production. This unit is one of the most energy-intensive units in TPP. Those systems are outdated, poorly automated and high energy-intensive. Furthermore, they must ensure efficient and safe operation of the facility while being environmentally friendly. The current work focuses on the process of grinding coals in ball drum mills for further pulverized combustion. An experimental study was performed in order to determine the main factors (rotational speed of the drum mill, the degree of loading with the grinding balls, and the velocity of the supplied air) that affect the efficiency of the fuel preparation system. The obtained experimental data and performed mathematical modeling resulted in regression equations describing the energy performance of the mill. Three regression equations for mill productivity, power consumed, and specific surface area of the final product were obtained and validated. The study reveals that the lowest specific energy consumption is achieved when the relative rotational speed of the mill is between 0.81 and 0.87; the weighted average diameter of the balls ranges from 33.5 up to 34.5 mm; the load factor of the grinding media ranges from 0.325 up to 0.335, the supplied air velocity is between 0.2 and 0.3 m/s. The proposed methodology allows adjustment of the operating parameters of the grinding process to achieve the lowest energy consumption. The power consumption for the preparation can be reduced up to 5 % for the selected operation mode of the grinding facility.

Published: March 2022

This paper describes the conceptual apparatus for the formation of information spaces of executors of educational projects in a dynamic environment. A multiple model of identification of the executor of an educational project was developed, taking into consideration the competence approach and dynamics of the components of the information space. To assess the competencies of the executors of educational projects, three components are calculated: the grade of the executor’s knowledge, the grade of the executor’s performance, the grade of the executor’s personal qualities. Based on the obtained grades, generalized assessments of the level of competence of each executor are formed. These grades for each executor of a particular educational project are used to determine the level of performance and potential of this project. To find a generalized grade of the project potential, the least square method was used to construct a regression line, which indicates a tendency to develop the competencies of project executors.
The stages of building information spaces of executors of educational projects in a dynamic environment were proposed. The hypothesis of the study that the progressive dynamic development of educational project executors has an impact on the potential of these projects was verified experimentally. To verify the described construction method, ten educational projects, which were implemented in the period from 2014 to 2020, were selected. The results indicate that the grade of the competencies of project executors recorded at the time of completion of a project almost completely coincides with the grade of evaluators after completion of the projects. The ranks obtained after the final evaluation of projects and the ranks according to calculated performance grades coincide by 40 %. Evaluation of projects is mainly focused on the reputation and performance of executors and does not sufficiently take into consideration the transformation of the competencies of executors during the implementation of projects.

Published: March 2022

This paper reports a seminal study whose relevance and significance are related to strengthening the importance of improving the distribution policy by introducing a model for optimizing the allocation of budget funds in the decision-making process. It has been determined that the potential of life support of the population in a region (PLSP in a region) acts as a tool for examining the resources in the region in terms of their capability to meet the needs of the population of the region in the current period and in the future. Based on the anthropocentric approach, it was determined that the main strategic resource is human potential that possesses a set of characteristics (components), which reflect its physical potential, the potential abilities and knowledge, as well as property potential. The implementation of the PLSP concept in the region has caused an urgent desire to study modern problems related to the budget and tax management of regional development, specifically, the management of budget expenditures at the stage of their allocation using modern means for supporting these processes. The expediency of using models of mathematical programming to determine the effective structure of the budget, taking into consideration the rate of inflation and the use of the methodology for calculating real wages, has been established. The following values for most priority areas of budget financing were calculated: the level of development of social infrastructure (11 %), the level of vocational training (29 %), the level of remuneration and entrepreneurial income (21 %), and the level of social payments to the population (14 %). It has been found that when a new allocation of budget funds is implemented, the value of the achieved level of PLSP development in a region could increase by 9 % compared to 2021.
The proposed approach is a permanently important prerequisite for the formation of priority areas of budget financing for the components of PLSP in a region in the process of producing and implementing universal and specific solutions in the field of budget and tax management.

Published: March 2022

A methodology for assessing the relative effectiveness of alternative options for building space object diversion systems has been improved. An algorithm for assessing the effectiveness of the system of removal of space objects from near-Earth orbit based on the method of integral assessment is given. It makes it possible to simplify the process of optimal choice of the method to divert space objects and determine efficiency in the early phases of the life cycle of rocket and space technology objects. The use of the appropriate toolset makes it possible to build a system for assessing the effectiveness of projects for the removal of space objects from low Earth orbits using various diversion methods (active, passive, combined). The analysis of defining world indicators of evaluation of objects of rocket and space technology based on regulations by international space agencies has been carried out. An indicator of the total integrated relative efficiency of projects of space object diversion systems from low Earth orbits has been proposed, which makes it possible to build the removal of passive, active, and combined methods for leveling the risks of space activities. It is argued that the selected combined system using an autophagic launch vehicle could reduce environmental losses and, as a result, reduce compensation payments to owners of space objects. The possibilities of building combined systems with reusable engines have been considered in order to reduce such indicators as the period of diversion and reduction of operating costs due to fuel economy.

Authors: Nikulina Olena , Severin Valeriy , Kotsiuba Nina
Published: March 2022

This paper proposes models and methods of the parametric synthesis of automatic control systems for a steam generator at a nuclear power plant, based on the modification of unconditional optimization methods. A mathematical model of steam generator control systems designed for the synthesis of model parameters has been considered. Algorithms are given for calculating level objective functions that take into consideration the limitations of variable parameters and quality indicators of problems for identifying and optimizing model parameters. The methods of unconditional optimization have been modified by introducing the operation of comparing the values of the level objective functions. Using the information technology of optimization, computational experiments were carried out to synthesize the parameters of the steam generator control systems by optimizing the level objective functions. The values of 54 parameters for the model of the control system in the PGV-1000 steam generator were identified, the value of standard deviation in the processes of 1 % from the experimental processes was achieved in the model. The result of parametric synthesis of optimal control systems for a steam generator produced a minimum control time of 131 seconds while the time of computational experiments did not exceed 10 minutes. The peculiarity of the proposed approach to the parametric synthesis of control system models is that the level objective function as a single mathematical object includes all the information about the synthesis problem. Therefore, a given approach is promising for simplifying software for solving complex problems of parametric synthesis of control systems. The considered technology of parametric synthesis of control systems could increase the degree of scientific validity of technical projects to improve various applied and promising control systems.

The necessity of digitalization of project management processes is shown, in particular, for the creation and use of the information standard of project management (ISPM). A model of using the information standard of project management to determine the planned parameters of projects has been developed. The principles and tasks of digitalization are formulated, the solution of which will allow to create such a standard. The analysis of existing theoretical and practical developments in this field is carried out. It is shown that the issue of creating an information standard of project management is still open. It is established that traditional software or databases are not suitable to meet the formulated requirements. This is due to the fact that they do not provide the necessary level of system and documentary support in the process of forming the information standard of project management. Therefore, it is proposed to use the information management system of enterprises and projects PrimaDoc to create such a standard. The concept of construction and use of the information standard of project management on the basis of the information management system PrimaDoc is offered. The structure of information technology for the formation of ISPM project-oriented company has been developed. The approach and tools for adjusting the environment of the PrimaDoc information management system to the technology of forming the ISPM of a project-oriented company are proposed.
Experimental research has been conducted, which showed a 65 % reduction in labor costs in the formation of ISPM. Practical approbation of ISPM information technology formation of project-oriented company on the basis of PrimaDoc system is executed. PJSC Tutkovsky (Ukraine) created an information standard of project management, which included more than 10,000 documents. The results of experiments and practical testing indicate the effectiveness of the developed concept and information technology of formation and use of information standard of project management.

Published: March 2022

It has been shown that existing methods and models for improving the noise immunity of communication channels are not capable of meeting requirements for the quality of information in mobile infocommunication systems. In addition, the compromised quality of information fails to protect it and provide the speed of information transmission and density of access channels.
It has been proven that reducing the level of electromagnetic radiation is the main method of ensuring noise immunity in wireless mobile communication systems of infocommunication systems. Therefore, one way to ensure the stable interference-free operation is to reduce the level of the information signal at the receiver input to the noise level when the signal/noise ratio is equal to one.
This paper reports the results of studying methods and models with correlation reception of ultra-wideband signals. It is proved that according to the level of potential noise immunity, the best indicators are shown by the model of encoding an ultra-wideband information signal by phase manipulation, followed by the coding model with opposite chips, and the code-time manipulation model.
It is shown that with a large base of the signal B>300 when the intensity of the received signals is below the level of interference, reliable transmission of information is carried out with a probability of error of less than 10-6. This proves that the use of ultra-wide signal technology allows for wireless hidden transmission of information with low radiation power and a low probability of error. Thus, at a speed of 12 Mb/s, it is possible to chain the transmission of information with a probability of error less than 10-6 if there is a large signal base used, B =500‒1000.

Published: March 2022

This paper reports the technology and equipment designed for manufacturing parts and components with predefined properties by 3D printing methods. Underlying the technology is the use of a beam of high-power electrons to smelt metal powder in a vacuum chamber with the formation of successive layers that repeat the contours of the digital model of the article.
The object of research is the process of surfacing articles from the Ti6Al4Vtitanium alloy powder. The purpose is to determine the optimal surfacing modes based on identifying the effect of process parameters on the quality indicators of articles.
The result of the study is the analyzed influence of technological parameters on the properties of articles. The optimum energy density of the beam of 44.5 J/mm3has been determined. Based on the research results, 25 experimental samples were printed. Three beam speed modes were used: 270, 540, and 780 mm/s. For each mode, the dynamic focusing current varied from −1.2 to 1.27 A in increments of about 0.3 A.
The articles were carefully examined. A method of raster electron microscopy was used to study the morphology of the samples' surfaces in several zones, namely in the central zone and along the contour; the roughness parameters of the surface micro relief, as well as the presence of defects (pores, non-melting, micro irregularities, inclusions), were established. It has been found that the articles are characterized mainly by a homogeneous micro relief of the profile. The structure of surfaces, formed in different zones depending on technological modes, differs in its morphology. Surfacing modes have been established that have the practical application: beam speed, 780 mm/s; power, 675 W; dynamic focus current, from –1.2 to 0 A. This provides for the minimal parameters of the surface micro relief and the absence of defects such as shrinkage pores, non-melting, as well as a minimum number of inclusions.

In this research, a numerical investigation has been conducted to analyze the dynamic load of the composite structure. The composite structure was solved and analyzed using the static structure tool. There is a physical model that has been imported and meshes have been done accordingly. Shear stress, von-mises stress, and total deformation are all considered as part of the analysis. Using finite elements to simulate the composite structure and response to the applied loads. Because dynamic loads were regularly applied, frequency response was examined.  In this study after verification of this computer simulation with experimental results and the results showed it was confidence 95 %. This percentage confidence allows proceeding numerical analysis. Deformation of the entire structure has been computed and found to be 10 mm, which is the maximum amount of overall deformation that can be caused by the applied load, In the Y-axis, a dynamic load was applied. The imposed dynamic load has been studied numerically and interpreted in terms of shear stresses. As a result of the maximum applied load, the maximum shear stress is 10 MPa. The complete composite construction was subjected to Von-Mises stress measurements. The structure's ability to withstand these stresses was determined by conducting a series of tests. The greatest von mises stress that can be applied in this study was 40 MPa. An investigation of how to react to vibration has already been carried out. In the numerical results, it was found that the reaction to the vibration was inconsistent. In terms of amplitude, the highest values may be found at 200 Hz, while the lowest values can be found at 20 Hz.

The aim. To conduct a comprehensive study of biphasic-type suppositories that contain diosmin and hesperidin.
Materials and methods. Samples of biphasic-type suppositories with a mass of 4.0 were objects of the study. Pharmacological, technological and analytical research methods were used to directly or indirectly analyze the strength and completeness of the drug activity. Thus, in this work we combined the study of the specificity of the pharmacological action of the drug, experimental verification of the quantitative content of API, analysis of the structural properties of suppositories and study of the profile of the release of active pharmaceutical ingredients.
Results. Therefore, based on the obtained data, the most effective dose was 75 mg / kg (in terms of a human dose of 300 mg per suppository). The drug in the selected dose showed a significant therapeutic effect, which significantly exceeded that of the test sample at a lower dose and the reference agent. According to the results of technological studies, it was determined that all samples of suppositories had satisfactory structural and mechanical properties. Studies of the histological structure of the mucous membrane of rats proved that there is a positive effect of treatment with suppositories with diosmin and hesperidin due to the improvement of the normal condition of the mucous membrane, the absence of edema and ulcerative defect. Research of the release profile of active pharmaceutical ingredients showed that the best percentage of release is characteristic of sample 2 (99.8 %)
Conclusions. Therefore, suppositories with diosmin and hesperidin in therapeutically dose of 75 mg/kg of animal weight can be used for further research and will be of interest in the treatment of hemorrhoids of both acute and chronic forms

Published: March 2022

Epilepsy is considered one of the most common chronic neurological diseases among humans. Lamotrigine is an effective new-generation anticonvulsant, which is widely introduced to the pharmaceutical market by various drug manufacturers. That is why the urgent aim for pharmaceutical analysis is developing of high precision, valid, accessible and quantitative methods for lamotrigine in pharmaceuticals.
The aim of the work is to study the optimal conditions for the reaction between lamotrigine and diazole red 2J, to define the coefficients of stoichiometric relationships in the “pharmaceutical substance – reagent” system and to develop a valid, sensitive and easy-to-follow technique for the quantitative determination of lamotrigine in pharmaceutical forms.
Material and methods. As reagent and solvent, diazole red 2J of AR grade and acetone of AR grade were used. Analytical equipment: Specord 200 spectrophotometer, ABT-120-5DM electronic scales, Elmasonic E 60H ultrasonic bath and measuring glassware of A class.
Results. A new spectrophotometric method for the quantitative determination of lamotrigine in four pharmaceutical formulations based on interaction with diazole red 2J in acetone medium has been developed. The proposed method is valid according to such validation characteristics as linearity, precision, intra-laboratory precision, accuracy, application range and robustness. The subordination to Behr's law is in the range of concentrations of 2.20–3.36 mg/100 ml. The LOD and LOQ values based on the values of the calibration line were 0.00450 % and 0.0138 % respectively. It was found that the studied coloured solutions are stable for at least 60 min and fluctuations in the amount of added red diazole 2J solution within ±10 % do not significantly affect the value of optical density. The coefficients of stoichiometric ratios between the components of the “lamotrigine – diazole red 2J” reaction mixture were defined by three methods and are 1:1. The predicted complete uncertainty of the results of analysis for quantitative determination of lamotrigine in the pharmaceutical form (2.2 %) does not exceed the maximum allowable uncertainty for the technique (3.2 %) and meets the SPhU requirements.
Conclusions. According to the experimental data, the technique can be correctly reproduced and it is suitable for using in laboratories of the State Inspection for Quality Control of Medicines and QCD of the chemicopharmaceutical enterprises

Development of an effective restaurant menu. Research and recommendations
Authors: Fedosova Kateryna
Published: March 2022

The restaurant menu is a key factor in the choice of certain dishes by the guest, and the profit of the establishment directly depends on this. The object of research is the restaurant business, and the subject is the influence of the restaurant menu on the choice of dishes by its consumers. One of the major problems is that restaurant owners often underestimate the importance of the structure and content of their restaurant menu – the names and descriptions of dishes, the sequence of their arrangement, the number of certain items, the selection and recording of prices, the quality of photographs and the overall appearance of the menu. This task is most often shifted to a graphic designer who does not have a certain competence in this matter.
The paper describes various psychological techniques that can have a direct impact on the choice of dishes by the guest on the menu. The method of menu engineering by Michael Kasanava and Donald Smith, the features of the psychology of choice and neuromarketing in the restaurant business are considered. The study used the methodology of focus groups and content analysis. 73 printed restaurant menus were analyzed and 3 focus groups were conducted with specific target audiences. Focus group participants were asked to familiarize themselves with different types of restaurant menus. During the discussion, the participants expressed their opinions, comments and recommendations on the arrangement of dishes in the menu, structure, number of positions, sequence of dishes, etc.
Interesting results were obtained, which proved the importance of not only the appearance and beautiful design of the restaurant menu, but also the need to pay great attention to its content, a certain arrangement of texts and structure. This is due to the peculiarities of the psychology of choice and neuromarketing.
Thanks to the study, recommendations have been developed on the use of certain psychological techniques for the menu of any restaurant. The implementation of the techniques described in the paper made it possible to create an effective menu for the BLOOM healthy food cafe (Odesa, Ukraine), which led to an increase in sales of the establishment by 15.8 % compared to the previous printed cafe menu.
Analysis of the physical and chemical properties of natural polysaccharides and the effect of dispersed glauconite mineral on them
Authors: Tochkova Oksana
Published: March 2022

The object of research is natural polysaccharides. One of the problems is the high cost and not always environmental friendliness of foreign analogues of these substances. Therefore, the methods of purification of polydisperse systems with the help of dispersed minerals, in particular separated dispersed mineral glauconite, purified and enriched up to 60 % of the initial content, are proposed.
The study used aqueous solutions of dextran and pectin, which added glauconite in the amount of 0.3 to 0.9 % by weight of the solution, heated to 60 ºC and kept for 10 minutes. Using glauconite in the amount of 0.3 % by weight of the solution gave high quality indicators. Thus, the dependence of the viscosity of polysaccharides dextran and pectin on the concentration of the introduced mineral was studied. The lowest value of viscosity is observed when adding 0.3 % glauconite to the mass of the solution, with increasing concentration, the viscosity increases.
The process of interaction of dextran molecules with the surface of glauconite is due to the fact that the proposed method of studying the viscosity has a feature that connects neighboring mineral particles through the dextran bridge and the formation of a stable gel structure. These structures are manifested in the form of partial groups of glauconite. This provides the ability to obtain such an indicator as adsorption. The mechanism of interaction of dextran with glauconite is confirmed by the dependence of the amount of dextran adsorbed on the surface of the mineral. Thus, at low concentrations of glauconite – up to 0.3 % adsorption of dextran on the surface increases, and with increasing concentration of glauconite – greatly decreases. This is crucial for the technological parameters of the mineral when using it in preparation processes, in comparison with similar adsorbents of unnatural origin. This will provide the benefits of glauconite over the use in the food industry and the regulation of the physicochemical properties of industrial polydisperse solutions as inexpensive additives of natural origin (stabilizers, thickeners, etc.) that are harmless to human health.

Bu araştırmanın amacı, okul yöneticilerinin liderlik stilleri ile öğretmenlerin yaşadığı örgütsel stres arasındaki ilişkiyi belirlemek ve bunu çeşitli değişkenlere göre değerlendirmektir. Araştırma 2020-2021 Eğitim-Öğretim yılında Şanlıurfa ili merkez ilçelerdeki kamuya ait genel liselerde görev yapan 377 öğretmen üzerinde yürütülmüştür. İlişkisel tarama ve korelasyonel araştırma modeli kullanılarak gerçekleştirilen araştırmada veriler, “Okul Müdürleri Liderlik Stili Ölçeği” ile “Örgütsel Stres Ölçeği” ile elde edilmiştir. Verilerin analizinde MWU ve KWH testleri ile Bonferroni Pairwise Comparisons ve Spearman’s Sıra Farkları korelasyon analizi kullanılmıştır.
Analizler sonucunda, öğretmenlerin toplamda orta düzeyde örgütsel stres algısına sahip oldukları belirlenmiştir. Alt boyutlar itibarıyla ise, öğretmenler, karar verme, iş yükü ve beceri kullanımı alt boyutlarında yüksek; sosyal destek alt boyutunda ise düşük stres algısına sahiptirler. Öğretmenlerin stres algıları branş hariç, demografik değişkenlere göre anlamlı farklılık göstermemektedir. Öğretmen algılarına göre, yöneticilerinin yaygın olarak sergiledikleri liderlik stili dönüşümcü liderlik (yüksek seviyede); bunu sürdürümcü liderlik (orta seviyede) ve serbest bırakıcı liderlik (düşük seviyede) izlemektedir. Öğretmenlerin algıladığı liderlik stilleri kıdem ve branş değişkenlerine göre anlamlı farklılık göstermiştir.
Öğretmen algılarına göre okul yöneticilerinin liderlik stilleri (toplamda) ile öğretmenlerin stres düzeyleri (toplamda) arasında negatif yönde (anlamlı ve zayıf düzeyde) bir ilişki belirlenmiştir. Bu ilişki alt boyutlara göre farklı yön ve değerlerdedir. Araştırmada, öğretmenlerin algıladığı örgütsel stresin, yöneticilerin liderlik stilinden ziyade, karar verme, iş yükü ve beceri kullanımı gibi öğretim sürecindeki işleyişle ilgili olabileceği değerlendirilmiştir. Bu itibarla, okul yöneticilerinin, öğretmen stresini artırmayacak ılıman bir çalışma iklimini sonuç verecek yönetim stili benimsemelerinin önemi vurgulanmıştır. Zira ister yönetim ve isterse öğretim sürecinin doğasından kaynaklanan öğretmen stresi, eğitim-öğretim faaliyetleri ile okulun etkililik ve verimliliğini düşüren önemli bir sorundur.
