Eurocentric or Indigenized Educational Curriculum: What Possible Option between Foreign Languages and National Languages (Fulfulde) in Education in the Far North Region of Cameroon?
Authors: Ngouo Herbert Rostand 
Published: October 2022

languages in education, as well as their opinion about the option of their replacement with Fulfulde, a lingua franca of the Northern regions of Cameroon.
The data were collected using a quantitative approach through a questionnaire administered to 525 informants, all residing in the Far regions of Cameroon. They originated from the three northern regions but the majority (90%) are native of the Far North. The multiple-choice questions (with 5 scales ranging from absolutely agree to absolutely disagree) aimed at eliciting the opinion of the respondents regarding the reformation of the LIEP by supressing the prevalence of foreign language over national languages, while upgrading the status of the latter in the secondary schools.
The findings reveal an attitude inclined in favour of foreign languages as the perspective of the substitution of foreign languages by Fulfulde as subject is not opted for. Foreign languages are perceived as being important. As a result, their presence in the Francophone education curriculum is seen as relevant and pertinent. Logically, it is suggested that their teaching be extended to the Anglophone system of education. As concerns instrumentality in social mobility, German is highly rated among foreign languages, and Italian is underrated. English and French are perceived as being more important that these foreign languages. Fulfulde is not perceived as relevant enough to replace FLs in education, however, national languages are seen as deserving a place in the school system.

Published: October 2022

Health workforce shortages worldwide are approaching crisis point, further burdening systems already struggling to meet demand. Doctor attrition has been identified as a major contributor to this problem and therefore, the current study examined links between workload demands and stressors, and doctors’ commitment. Based on prior research and key psychological theories, pathways were hypothesised that were initiated by workload demands and stressors, proceeding through work-life conflict and psychological distress, intrinsic motivation factors, through to commitment. A sample of 208 medical doctors completed self-report measures of these constructs. Among workload hassles and demands, quantitative demands, representing the extent that workload exceeds available resources (e.g., time) emerged as the strongest predictor. Meaningfulness of work was the strongest direct predictor of commitment, followed by work-life conflict, job satisfaction and burnout. This study highlights the importance for workplaces providing an environment that nurtures doctors’ intrinsic motivation and manages doctor workloads to ensure work-life balance is maintained.
Regarding Classification of n-sharing of Multivariate Mappings over Finite Fields and One NSUCrypto'2019 Olympiad Problem
Authors: Chilikov A. A. 
Published: October 2022

A problem of great importance that arises in designing and implementation of a cryptosystem is countering side channel attacks. Often an appropriate mathematical algorithm, implemented on a specific physical device to work in the physical environment, becomes vulnerable to such attacks.The “function sharing” technique is a prospective and efficient way to avoid this problem. In the paper we investigate “non-complete sharing” of Boolean functions and mappings, and functions and mappings over finite fields and provide a complete description of the set of functions with n variables, which have sharing.The main findings are the following: introducing and investigating a new concept of “weak” non-complete n-sharing, establishing its connection with “weak” and “classical” n-sharing, and substantiating its advantages from the algebraic point-of-view as well as establishing and proving a criterion for the existence of weak non-complete n-sharing for an arbitrary function. The results also include an explicit description of a set of functions which have weak sharing in terms of algebraic normal form, obtaining the precise and simple descriptions for the boundary (“border”) cases: n = 2, n=m and binary fields. Applying these results to the AES S-box allows complete solving the problem, i.e. a complete answer to the question of a representability of the S-box of the AES cipher as a sharing is available. We believe that the same way can be successful for other cryptographic algorithms.
Analysis of the Mathematical Model of Cancer Dynamics
Authors: Podderegin O. A. 
Published: October 2022

Qualitative analysis of dynamic systems is a powerful research tool used to solve a great deal of application problems. In mathematical models described by ordinary differential equations, the study of equilibrium positions has actually become the standard: their number and location depending on the parameters, as well as issues of local stability. In mathematical models in various fields of chemistry and biology, it is also important that the natural requirements for the possible values ​​of phase variables are not violated in the process of dynamics (as a rule, this is the non-negativity condition). More sophisticated study orientation is global sustainability.The need for a qualitative analysis of a dynamic system arises because, as a rule, differential equations are not integrated and it is impossible to define the general properties of the system trajectories by integration. However, even if the system of differential equations is integrated, the formulas can be so cumbersome that their use in the analysis of the system dynamics turns out to be a challenge.In this paper, we study an 8-dimensional system of ordinary differential equations that describes the dynamics of cancer during chemotherapy and immunotherapy. The phase space of the system is a non-negative orthant.The paper studies the equilibrium positions of the system. There is always one equilibrium in a system, but there may be two more equilibria. There are conditions for the system parameters found, under which the equilibrium position, being always present is asymptotically stable. Moreover, there is a provement that the asymptotic stability is global.
Grid Method for Solving an Initial-Boundary-value Problem for a General Multidimensional Equation of Parabolic Type

Published: October 2022

The problems concerning the physical process studies that lead to mathematical models based on a parabolic type equation are of great practical importance.When solving the parabolic equation, a transition from the one-dimensional equation to the multidimensional one gives a rise to some difficulties. The trouble is that amount of computations significantly increases in the transition from the one-dimensional problems to the multidimensional ones In this regard a task to build the economical difference schemes for a numerical solution of multidimensional problems is a challenge.A difference scheme that approximates the problem over time is economical, if it is unconditionally stable and the desirable number of arithmetic operations in the transition from layer to layer is proportional to the number of nodes in each time layer.The paper dwells on the construction of a locally one-dimensional (economical) difference scheme for the approximate solution of a parabolic type equation of a general form in a multidimensional domain, the main idea of which is to reduce a complex problem to a sequential solution of boundary value problems of a simpler structure. At the same time, there is a construction of the economical, unconditionally stable difference scheme for each of the intermediate problems. To have a numerical solution of the problem, there is a construction of the locally one-dimensional difference scheme of A.A. Samarsky. Using a method of energy inequalities allows us to obtain a priori estimates in the differential and difference interpretations, whence it follow that there are the uniqueness, stability, as well as the convergence of the solution of the locally one-dimensional difference scheme to the solution of the original differential problem. For a bi-dimensional problem, a numerical solution algorithm is constructed.

Published: October 2022

Reducing pneumatic valves, which are part of modern pneumatic control systems, are widely used in the automation of production and technological processes in various fields of technology. The efficiency of using pressure reducing valves depends on their parameters and characteristics. To select the optimal parameters of pressure reducing valves, various methods are used based on the search for the minimum of the target (target or criteria) function.The object of study is a three-line direct-acting pressure reducing valve, which ensures the determination of its optimal parameters. To calculate the optimal parameters of the pressure reducing valve, the method of orthogonal experimental design was applied. The main advantage of this method is that in this case all variables are varied simultaneously.The article presents the design features of a three-line direct-acting pressure reducing valve.The developed mathematical model of a pressure reducing valve is presented, which is a system of equations for a three-line direct-acting pressure reducing valve, which should be used to select the optimal parameters of the pressure reducing valve.To calculate the optimal parameters of the pressure reducing valve, the method of orthogonal experimental design was used. As an optimality criterion, the integral criterion of the squared error of the transient process, the change in the pressure level in the outlet line of the valve, was chosen.The optimal parameters of the pressure reducing valve are found, and transient processes of pressure change in the outlet line of the pressure reducing valve are calculated. The main requirements for optimization and selection of the optimal parameters of pressure reducing valves are formulated. A comparison of the transient processes of the outlet pressure before and after optimization is given.Based on the results of the work, the following conclusions were drawn:From the obtained comparative results of the transient processes of the level of outlet pressure in the outlet of the pressure reducing valve before and after optimization, it was found that after optimization the pressure reducing valve has a faster response.The speed has been increased from 0.35 s to 0.27 s, that is, the speed has increased by 1.30 times.The transient overshoot is less than 5%, and the static error is reduced by 1.9% and is completely eliminated.
Product and process innovation patterns in Polish low and high technology systems
Authors: Dzikowski Piotr 
Published: October 2022

Research background: While the Sectoral Innovation System (SSI) anticipates technology-related similarities in innovation patterns in the same sectors across countries, the distance to the frontier suggests that there are important differences with respect to the level of national technological development. Most contemporary analyses of sectoral innovation systems are focused on well-developed economies. In contrast, the evidence from developing countries including new EU members are scared and lack dynamics.
Purpose of the article: The purpose of this paper is to identify and compare product and process innovation patterns in Polish low and high technology systems. The main assumption is that divergence and convergence in innovation patterns of low- and medium-low technology (LMT) and high technology (HT) systems evolve over time and are strongly influenced by the characteristics of firms, their linkages with other system participants, existing demand, and institutional conditions.
Methods: According to the third edition of the Oslo Manual (OECD, 2005), we employ a harmonized questionnaire and methodology to collect unique micro data on innovation. The survey concerns 5252 firms including 873 firms from HT sector. The scope of the research relates to product and process innovation at least new to the firm.
Findings & value added: Our results show that although the intensity of product and process innovation is higher in HT system, both business support institutions and public financial instruments better support firms in LMT sectors. On the other hand, existing demand and market structure favor the emergence of new innovations at the firm level (imitations), but with more emphasis on LMT. The key source of innovation is suppliers, with foreign suppliers in HT and national ones in LMT. In contrast to leading economies, LMT plays a key role in long term economic growth in Poland.
