Trim Analysis and Structured H-Infinity Control of Wing-Docked Multibody Aircraft
Authors: Qi Pengyuan , Li Qingxian , Wang Yinan
Published: February 2024

A wing-docked multibody aircraft is a novel configuration being explored as a balanced solution between efficiency and structural resilience for very long-endurance aviation. The presence of wingtip hinges complicates the dynamics and control of this class of aircraft but has thus far only been analyzed in specific cases. In this work, we make a comprehensive exploration of parameter space of the multibody trim problem and stability and demonstrate the treatment of the control problem using the robust [Formula: see text] synthesis technique. We propose a simplified simulation approach to the static trim analysis and demonstrate key observations relating to the configurations and open-loop dynamic stability of multibody aircraft in general. An interpolated parameter-scheduling model using the hinge angle as a scheduling parameter is established, based on which the structured multimodel [Formula: see text] synthesis method is employed to synthesize the robust flight controllers. Simulation results show that the designed controllers are capable of configuration control within the range of possible trim solutions and have also achieved good control effectiveness in path following and disturbance rejection. The proposed trim analysis and control techniques serve to provide a systematic benchmark study on wing-docked multibody aircraft dynamics, which is valuable to the development of this research area.

Published: February 2024

This paper summaries factors affecting teachers’ decision to use ICT (Information and Communication Technology) in teaching modern languages. This paper tries to understand the teachers’ ICT uptake from ecological perspective discussing that teachers’ attitudes are influenced by environments in different levels (e.g. micro, meso, macro). In this paper, the environments refer to micro as teacher, meso as institution, and macro as beyond institution levels. Teacher levels define the aspects related to teachers’ psychological and demographic characteristics. Institutions levels describe the teachers’ decision from the influence of support and social circle in the institution. Beyond institution levels discuss the influence from wider environments such as government and public demand.
Effect of oral vitamin E supplementation on lipid profile in diabetes mellitus: evidence based case report
Authors: Wulandari Indah Sri , Sutanto Krisadelfa
Published: February 2024

Introduction: Diabetes mellitus, a prominent non-communicable disease, presents as a chronic condition associated with various complications, including heart disease, nerve damage, chronic kidney disease, and dyslipidemia. A pivotal abnormality in diabetic dyslipidemia is insulin resistance, which stimulates the production of Hepatic VLDL1 (very-low-density lipoprotein 1). The resulting overproduction of VLDL1 is metabolically linked to an abundance of small, dense LDL (low-density lipoprotein) particles and a reduction in large, cholesterol-rich HDL2 (high-density lipoprotein). Conversely, vitamin E, known for its antioxidant and anti-inflammatory properties, acts as a remover of peroxyl radicals, preventing lipid oxidation and safeguarding polyunsaturated fatty acids (PUFA) within cells and plasma lipoproteins.

Method: This study investigates the impact of oral vitamin E supplementation on the lipid profile in diabetic patients. Employing advanced search techniques on databases like PubMed, Cochrane Library, and Google Scholar, we conducted a comprehensive literature search using MeSH terms, advanced search methods, and specific eligibility criteria. The results yielded one systematic review with a meta-analysis and two randomized controlled trials (RCTs) that met the predefined PICO and eligibility criteria.

Results:  The systematic review and meta-analysis, along with one RCT, reported no significant reduction in lipid profiles with oral vitamin E supplementation in diabetic patients. In contrast, the other RCT observed an improvement in lipid profiles among diabetic patients receiving oral vitamin E supplementation.

Conclusion: Supplementing with oral vitamin E does not enhance the lipid profile of individuals with diabetes mellitus.

Authors: Ferdi Jessica , Diana Sunardi
Published: February 2024

Background: Osteoarthritis is marked by mild inflammation, causing cartilage damage that leads to bone remodelling and potentially reduces the quality of life. Omega-3 has anti-inflammatory properties, which can help mitigate cartilage damage.

Objective: This research aims to determine the role of omega-3 in relieving pain in patients with osteoarthritis.

Methods: A literature search was conducted using advanced searching on three large databases: PubMed, Cochrane, and Scopus. The search used Mesh terms according to the criteria. After assessing the relevance and suitability of the literature, two articles were selected and critically evaluated based on Oxford Center for Evidence-Based Medicine.

Results: Two systematic review-meta-analyses that meet the PICO and eligibility criteria were found. One of the literature sources does not demonstrate the effect of omega-3 supplementation on joint pain, while the other literature source shows the beneficial effects of omega-3 in reducing joint pain in osteoarthritis.

Conclusion: Omega-3 supplementation can alleviate joint pain in individuals with osteoarthritis. Providing omega-3 may be worth considering.

Authors: Palupi Nadya Suci , Chandra Dian Novita , Februhartanty Judhiastuty , Khusun Helda , Hanisa Nisrina , Dewi Dian Kusuma
Published: February 2024

Background: The COVID-19 pandemic has transformed eating habits, leading to an increased reliance on online food delivery. It's crucial to comprehend the diet quality and food choices among female users during this period.

Objective: This study aims to explore the association between diet quality score and the food choice motives among female online food delivery users during the COVID-19 pandemic

Methods: This online cross-sectional study involved surveying 405 female users recruited through consecutive sampling. The Food Choice Values Questionnaire (FCVQ) was utilized to understand their food choices, while nutrient intake and diet quality were assessed using the Nutrient-Rich Food 9.3 Index Score (NRF 9.3). Subsequently, the collected data underwent both univariate and multivariate analyses. Potential biases might arise due to time constraints during the pandemic and reliance on self-reported online data. Moreover, the method used to measure nutrient intake might not be ideal for this demographic, lacking tailored tests. Nonetheless, it’s important to highlight that the survey underwent prior validation among Indonesian adults, affirming its broad applicability.

Results: Female users showed low average NRF 9.3 scores (241.67), indicating poor diet quality. Their prioritized food choice motives were also low. Significant associations surfaced between NRF 9.3 scores and food choice motives—tradition (p<0.01, r: 0.229), comfort (p<0.01, r: 0.223), organic (p<0.01, r: 0.231), safety (p<0.001, r: 0.162), weight control/health (p<0.01, r: 0.171), and income (p<0.05).

Conclusion: The NRF 9.3 score is likely to increase when there are higher scores for tradition, comfort, and organic factors, and when income exceeds the minimum regional wage.

Published: February 2024

Furfural is a pivotal renewable platform molecule obtained from the chemical breakdown of hemicellulose. While it has traditionally been valorized to value-added chemicals through catalytic hydrogenation in biorefineries, its direct electrocatalytic hydrogenation presents attractive advantages. This article describes the significant improvements brought by the structuring of copper cathodes applied to this process, in terms of activity and selectivity. We show that structured electrodes are capable of converting furfural to furfuryl alcohol with 100% selectivity at potentials as high as - 0.2 vs. the reversible hydrogen electrode (RHE) in neutral conditions (pH 7.0). Moreover, the same electrode can selectively generate either furfuryl alcohol or 2-methylfuran in acidic conditions (pH 1.0), depending on applied potential and temperature. We further show the existence of optimal voltage-temperature conditions for the efficient conversion of furfural to furfuryl alcohol or 2-methylfuran, highlighting the delicate influence of operating conditions on the selectivity of furfural reduction, in competition with the hydrogen evolution reaction in aqueous electrolytes. These performances are attributed to the resilience of Cu (I) species under operating conditions and their likely contribution to the electrocatalytic active site, as revealed by quasi-in-situ photoelectron spectroscopy.

Published: February 2024

Development of photocatalytic systems that facilitate mechanistically different steps in complex catalytic manifolds by distinct activation modes can enable previously inaccessible synthetic transformations. However, multimodal photocatalytic systems remain understudied, impeding their implementation in catalytic methodology. We report herein a photocatalytic access to thiols that directly merges the structural diversity of carboxylic acids with the ready availability of elemental sulfur without substrate preactivation. The photocatalytic transformation provides a direct radical-mediated segue to one of the most biologically important and synthetically versatile organosulfur functionalities, whose synthetic accessibility remains largely dominated by two-electron-mediated processes based on toxic and uneconomical reagents and precursors. The two-phase radical process is facilitated by a multimodal catalytic reactivity of acridine photocatalysis that enables both the singlet excited state PCET-mediated decarboxylative carbon–sulfur bond formation and the previously unknown radical reductive disulfur bond cleavage by a photoinduced HAT process in the silane–triplet acridine system. The study points to a significant potential of multimodal photocatalytic systems in providing new directions to previously inaccessible transformations.
Performance of a DOW BW30 RO membrane for the separation of nopinone from methanol-water solvent
Authors: Hallamasek Sabine , Freger Viatcheslav , Lapkin Alexei
Published: February 2024

Reverse osmosis (RO) membrane technology represents a low-cost, low-energy alternative for the separation of multi-component organic mixtures. However, limited availability of experimental data renders the design of such systems challenging. Moreover, mixtures containing multiple solvent species complicate the applicability of common membrane transport models. This study presents experimental data on the dead-end batch separation of nopinone, a useful intermediate in the chemical industry, from mixed methanol-water solvent across a DOW BW30 RO membrane. Membrane rejection and flux values were determined for feed concentrations of 0.449 – 1.099 M. Data analysis via the solution-diffusion model revealed the presence of convective transport in the investigated system, while the Spiegler- Kedem model obtained a reasonable system description when using a single coefficient for mass transfer description. Accurate calculation of osmotic pressure in the mixed-solvent system was found to impact data analysis due to the effects of non-ideality on the transmembrane driving force. From the Spiegler-Kedem model, permeability coefficient values A and B were yielded of order 10-7 and 10-8, respectively, with a membrane selectivity of ~30 bar-1. Finally, the system’s separation performance in continuous cross-flow was estimated by considering a series of dead-end batch separation units, suggesting feasible system operation at industrial scale.

Published: February 2024

Fundraising using the equity crowdfunding method has experienced rapid development and is in high demand from the public. In order to maintain the credibility of the implementation of Islamic securities crowdfunding, it is essential to establish a sharia supervisory board to supervise the offering of sharia-compliant securities employing information technology-driven crowdfunding service platforms. This article aims to discuss and analyze the position and role of the sharia supervisory board within the system, as well as the level of compliance with sharia principles in the implementation of equity crowdfunding in Indonesia. The research method used in this article is a type of normative legal research that relies on secondary data sources obtained through a literature review. The legal protection for the existence of a sharia supervisory board in sharia equity crowdfunding in Indonesia is regulated in POJK Number 57/POJK.04/2020 and Fatwa Number 140/DSN-MUI/VIII/2021. The sharia supervisory board has a very strategic role in ensuring sharia compliance in every equity crowdfunding activity in Indonesia. In order to maintain the credibility of sharia equity crowdfunding in the future, it is essential to ensure that every aspect of operations complies with sharia principles by maximizing the existence of a sharia supervisory board.
On some hypergeometric Sobolev orthogonal polynomials with several continuous parameters
Authors: Zagorodnyuk Sergey
Published: February 2024

In this paper we study the following hypergeometric polynomials: $$ \mathcal{P}_n(x) = \mathcal{P}_n(x;\alpha,\beta,\delta_1,
\dots,\delta_\rho,\kappa_1,\dots,\kappa_\rho) = $$ $$ = {}_{\rho+2} F_{\rho+1} (-n,n+\alpha+\beta+1,\delta_1+1,
\dots,\delta_\rho+1;\alpha+1,\kappa_1+\delta_1+1,
\dots,\kappa_\rho+\delta_\rho+1;x), $$ and $$ \mathcal{L}_n(x) = \mathcal{L}_n(x;\alpha,\delta_1,\dots,
\delta_\rho,\kappa_1,\dots,\kappa_\rho) = $$ $$ = {}_{\rho+1} F_{\rho+1} (-n,\delta_1+1,\dots,\delta_\rho+1;
\alpha+1,\kappa_1+\delta_1+1,\dots,\kappa_\rho+\delta_\rho+1;x),
\qquad n\in\mathbb{Z}_+, $$ where $\alpha,\beta,\delta_1,\dots,\delta_\rho\in(-1,+\infty)$, and $\kappa_1,\dots,\kappa_\rho\in\mathbb{Z}_+$, are some parameters. The natural number $\rho$ of the continuous parameters $\delta_1,\dots,\delta_\rho$ can be chosen arbitrarily large. It is seen that the special case $\kappa_1=\dots=\kappa_\rho=0$ leads to Jacobi and Laguerre orthogonal polynomials. Of course, such polynomials and more general ones appeared in the literature earlier. Our aim here is to show that polynomials $\mathcal{P}_n(x)$ and $\mathcal{L}_n(x)$ are Sobolev orthogonal polynomials on the real line with some explicit matrices of measures. The importance of the orthogonality property was our main reason to concentrate our attention on polynomials $\mathcal{P}_n(x)$ and $\mathcal{L}_n(x)$. Here we shall use some our tools developed earlier. In particular, it was shown recently that Sobolev orthogonal polynomials are related by a differential equation with orthogonal systems $\mathcal{A}$ of functions acting in the direct sums of usual $L^2_\mu$ spaces of square-summable (classes of the equivalence of) functions with respect to a positive measure $\mu$. The case of a unique $L^2_\mu$ is of a special interest, since it allows to use OPRL to obtain explicit systems of Sobolev orthogonal polynomials. The main problem here is \textit{to choose a suitable linear differential operator in order to get explicit representations for Sobolev orthogonal polynomials}. The proof of the orthogonality relations is then a verification of such a choice and it goes in another direction: we start from the already known polynomials to their properties. We also study briefly such properties of the above polynomials: integral representations, differential equations and location of zeros. A system of such polynomials with a kind of the bispectrality property is constructed.
ВЫБОР АДЕКВАТНЫХ ПОТЕНЦИАЛА И МЕТОДОВ РАСЧЕТА КВАНТОВЫХ СОСТОЯНИЙ АКСИАЛЬНО КАНАЛИРОВАННЫХ ЭЛЕКТРОНОВ ПРИ ВЫСОКИХ ЭНЕРГИЯХ
Authors: Калашников Н. П. , Ольчак А. С.
Published: February 2024

В работе рассматривается движение релятивистских частиц (электронов) вдоль плотноупакованных цепочек атомов в монокристаллах (аксиальное каналирование). Движение электронов рассматривается в сопутствующей системе отсчета (ССО), которая сама движется со скоростью, равной продольной оси каналирования компоненте скорости каналированной частицы. В ССО движение аксиально-каналированной частицы является двумерным (плоским), причем для электронов с энергиями до нескольких гигаэлектрон-вольт оно будет нерелятивистским, как в атоме водорода. Квантовые характеристики движения определяются энергией частицы (она играет роль массы электрона в двумерном «атоме»), а также параметрами усредненного потенциала атомной цепочки, зависящими от кристаллографического направления и химического состава кристалла. Аксиальное каналирование вполне можно рассматривать как уникальную модель релятивистского двумерного атома с управляемыми параметрами. В работе показано, что основные характеристики квантовых состояний поперечного движения частиц при аксиальном каналировании слабо чувствительны к функциональной зависимости параметров усредненного потенциала от поперечных координат. Для расчета таких характеристик удобно использовать приближенный метод квантования Бора, позволяющий получить результат аналитически. Модифицированный метод квантования Бора можно применить для расчета характеристик поперечного движения, выходящего даже в ССО за рамки нерелятивистского приближения. В работе рассчитаны энергетические спектры допустимых состояний поперечного орбитального движения для нескольких вариантов модельных аксиально-симметричных потенциалов. Показано, что, несмотря на различия в структуре, средние расстояния между энергетическими уровнями слабо нечувствительны к выбору модели потенциала. Найдены энергии уровней как для случая, когда для описания поперечного движения в ССО применимо нерелятивистское приближение, так и в ситуации, выходящей за рамки нерелятивистского приближения.
History Teacher Training from Decolonial Curriculum Practices to Combat Racism at UniProjeção in the Federal District — A Secondary Publication
Authors: Ramos Karoline da Silva , Nascimento Cláudia Pinheiro , Ferrer Francisca Carla Santos
Published: February 2024

This article aims to understand the training process of history undergraduates, to see if there are decolonialcurricular practices to combat racism at the Centro Universitário e Faculdade Projeção (UniProjeção) in the Federal District, to understand how coloniality has corroborated the exclusion of different epistemologies and the erasure of different cultures, and how this exclusionary process of coloniality interferes in the training of history teachers. In order to combat this practice, we are looking for alternatives that can break these suppressions carried out by Europeans. In this way, we turn to decolonial ideas that aim to break with the logic of coloniality. We can conclude that these practices are poorly developed in the institution, so we proposed active problem-based methodology and music as a didactic resource. As playful educational tools that strengthen the teaching-learning process, they are active agents in the decolonial work of combating racism, and it is essential to train responsible and ethical teachers in the fight against racism and any form of oppression.
Nontyping virulence factors of Clostridium perfringens
Authors: Svobodová Irena , Hulánková Radka
Published: February 2024

The anaerobic, rod-shaped, spore-forming bacterium Clostridium perfringens is known for its production of biochemically active substances. Most of them are proteins that have a pathogenic effect on a wide range of animal tissues and cause a specific syndrome or even a disease in humans or animals. Production of toxins is used to classify isolates of C. perfringens into 7 different toxin types (A–G). Other virulence factors (i.g. beta2-toxin, BEC toxin, sialidases, hyaluronidase etc.) only indirectly or partially participate in the development of the disease, and the function of some substances has not been fully elucidated. The article summarizes basic data on the non-typing virulence factors of C. perfringens.

SYSTEMATIC REVIEW: PEMODIFIKASI GENETIK β-THALASSEMIA
Authors: Syafira Mutia , Sribudiani Yunia , Maskoen Ani M
Published: February 2024

Thalassemia merupakan penyakit herediter yang diturunkan secara autosomal resesif. Thalassemia dibedakan berdasarkan variasi mutasi pada gen globin yaitu gen a-globin (HBA) pada α-Thalassemia dan β-globin (HBB) pada β-Thalassemia. Berdasarkan tingkat keparahan gejala klinis, Thalassemia diklasifikasikasikan menjadi Thalassemia Mayor (TM), dan Intermedia (TI). Pada kasus β-Thalassemia, tingkat keparahan klinis selain dipengaruhi mutasi pada gen HBB, juga dapat dipengaruhi oleh co-inheritance mutasi pada gen HBA atau adanya genetic modifier (pemodifikasi genetik).  Pemodifikasi genetik ini dapat berupa polimorfisme ataupun mutasi pada gen-gen maupun regio pada genom yang terlibat pada regulasi ekspresi kluster gen β-globin. Beberapa studi melaporkan polimorfisme dan/atau mutasi pada gen KLF1, BCL11A dan regio intergenik HBS1L-MYB sebagai pemodifikasi genetik β-Thalassemia. Fokus review artikel ini adalah memperbarui informasi terkait mutasi dan polimorfisme pada gen-gen dan regio pemodifikasi genetik β-Thalassemia serta ekspresi fenotipiknya.

Purpose: The main aim of this article is to determine the usage of social media in university teachers' educational activities, along with identifying the primary obstacles. Design/methodology/approach: The study was carried out using the CAWI (Computer Assisted Web Interview) method. The data was gathered in June 2023 by surveying a sample of academic instructors at the Faculty of Organisation and Management at Silesian University of Technology. Findings: The findings indicate that social media is scarcely used by the academic staff for teaching purposes, but rather for communication with students. Remarkable differences were observed between generations. Younger academic educators appear to demonstrate a greater willingness to use social media tools in their work, both in communication with students and during lectures. Research limitations/implications: A limitation of the study is the size of the research sample. This may indicate the direction of future research concentrating on using social media in different activity areas by academics. Practical implications: Students, who are one of the main users of social media, use these online platforms to enhance their learning in a variety of subjects. Teachers should also use these tools to improve their teaching process by making it more attractive. Originality/value: This paper addresses knowledge gaps regarding the use of social media in working with students. Its findings can aid academics in developing strategies for using social media in the classroom. Keywords: social media, academic teachers, teaching. Category of the paper: research paper.
Education in time of pandemic crisis – case study
Authors:   Silesian University of Technology, RMS2, Banasik Arkadiusz , Pikiewicz Piotr ,   Silesian University of Technology, RMS2
Published: February 2024

Purpose: The crisis caused by the Covid-19 pandemic has seriously impacted the way we work, learn and behave in everyday life. We were forced to work from home, i.e. work remotely, and learn using methods that were rarely or even not used until the pandemic. Switching from classes at the university with direct contact with the teacher to online classes had advantages, but also some disadvantages. Some universities already had some experience in conducting online classes and knew how to use them for various types of studies. Other universities took advantage of the platforms offered by international organizations, prepared new forms of education and adapted the program to their technical capabilities. New forms of education turned out to be a big challenge for both students and professors. The aim of the study was to compare the methods of distance education used both in universities with extensive experience and in universities where distance learning, at least due to applicable legal regulations, was less popular. Design/methodology/approach: The article analyzes the distance learning methods used by universities. The results of interviews conducted with students, teachers and the authors' personal experiences are described. Findings: We have discovered that students have no problems using online education techniques and highly value the opportunity to use materials prepared by lecturers and made available on remote education platforms. Moreover, they derive satisfaction from the opportunity to learn independently and search for materials on the Internet. One of the main conclusions was that the future seems to belong to a blended learning system, combining physical and online learning. Originality/value: The value is the originality based on the interviews and post COVID point of view. Keywords: pandemic crisis, online education, case study. Category of the paper: Case study, Viewpoint.
Ethical determinants of market behavior of contemporary enterprises
Authors:   University of Gdansk, Majecka Beata
Published: February 2024

Purpose: Increasingly, consumers and competitors are reviewing business behavior in the context of ethics. Ethics and ethical business strategies are becoming important factors in the success of modern business entities. The research objective of the article is to identify (on the basis of the cited cases) some of the ethical determinants of market behaviour of the enterprises in the conditions of modern economy. Design/methodology/approach: The study is based on a review of the literature on ethical issues in the economy, particularly the requirements for companies by the wider environment and stakeholders. An important element of the study is the presentation of specific cases of entities that change their market behaviour under the influence of these requirements. Findings: The main conclusion that can be drawn from the research presented concerns the increasing involvement of ethical aspects in the decision-making processes of companies operating in today's market. The environment's expectations of companies are changing - it is no longer enough to provide specific products or services to meet needs or to generate profits for shareholders. What matters more and more are the ways in which these products or services are created, as well as the willingness to accept profit limits in the context of the sustainable development of the entire socio-economic system. Social implications: The social impact of the issues raised in this study is revealed in two aspects. Firstly, by analysing the business cases presented in the study, it is possible to realise that ethical and economic objectives need not be and are not in conflict. Secondly, showing ethical aspects that are also important in business activities can lead to the development of public awareness of the relevance of issues that have so far often been overlooked in discussions on the economy. Originality/value: A valuable element of the study is to point out that it is possible to successfully combine the ethical aspects of businesses with the desire for financial success. Keywords: functioning of enterprises, market behaviour of enterprises, ethical requirements. Category of the paper: viewpoint, case study.
Nonlinear granger causality between natural gas and heating oil prices and selected exchange rates
Authors:   University of Economics in Katowice, Zeug-Żebro Katarzyna
Published: February 2024

Purpose: The currently observed uncertainty in financial markets related to changes taking place in the modern world requires investors to look for tools that allow for good forecasting of the price of financial instruments. The detection of causal relationships may contribute to improving the quality of forecasts by reducing the variance of the prediction error. The aim of the research is to detect nonlinear Granger causality in both directions between selected financial instruments and to check whether the identified relationships are stable over time. Design/methodology/approach: The study of causal relationships between selected financial instruments was carried out using the nonparametric Diks-Panchenko test. This test identifies all types of relationships: linear and nonlinear. Findings: In the first phase of the study, nonlinear Granger causality was tested using the nonparametric Diks-Panchenko test. Six values of lags and two distance measures were used. It is then shown that the significance of the detected relationships has changed in recent years. For this purpose, two directions of causality and three sub-periods were analyzed. Research limitations/implications: Due to the short-term character of the detected relationships, they should be taken into consideration primarily by market participants, to create effective investment portfolios and risk-hedging strategies. Practical implications: Application in making investment decisions on the capital market. Originality/value: The use of information on causal relationships to improve the quality of forecasts related to the energy and currency markets. Keywords: nonlinear Granger causality, Diks-Panchenko test, heating fuel market, exchange rates. Category of the paper: Research paper.
The importance of knowledge transfer in the implementation of an integrated ERP system
Authors:   Bydgoszcz University of Science and Technology, Zwierzchowski Daniel
Published: February 2024

Purpose: Importance of knowledge transfer in the process of implementing an integrated ERP class IT system. Design/methodology/approach: The chosen research approach involved a case analysis, employing two distinct data collection methods an unstructured interview with a member of the implementation team and observation conducted by the article's author. The rationale behind investigating knowledge transfer in ERP systems implementation projects is well-founded, as it is deemed essential for enhancing the overall efficiency of project management in this domain. Findings: The research demonstrates a clear correlation between the stages of the knowledge life cycle and those of the project. In the project's preparatory phase, essential organizational knowledge is identified. Subsequently, during the IT solution design phase, there is a transfer of knowledge from employees to consultants, contributing to the development of a cohesive IT solution project. This project is then implemented in the subsequent phase, leveraging organizational knowledge for solution creation, testing, and utilization. Research limitations/implications: The insights presented in this study pave the way for additional theoretical and practical exploration. The adoption of an integrated ERP class IT system represents a strategic decision with profound implications for business processes, resource utilization, and management efficiency. The ramifications of this decision underscore its pivotal role in shaping the overall trajectory of organizational operations. Practical implications: The implementation process demands a spectrum of diverse and often specialized knowledge from participants, leading to multidirectional flows of such knowledge. Consequently, there arises a crucial necessity for research into knowledge transfer methodologies within the design environment. Originality/value: Implementation projects necessitate a range of diverse, often specialized knowledge from participants and entail multidirectional flows of such knowledge. The focal point of these projects is the amalgamation of organizational, management, business, and technological knowledge possessed by all participants, encompassing future users of the integrated system. Keywords: ERP systems, knowledge transfer, small and medium-sized enterprises. Category of the paper: Case study.
Employee information in the field of CSR and diagnosis and resolution of the labour conflict
Authors:   Cracow University of Economics, Emerling Izabela , Kozłowska-Makóś Danuta ,   University of Economics in Katowice
Published: February 2024

Purpose: The aim of the article is to present the disclosed non-financial information in the area of employees on the example of the examined company and the strategy used by the management to diagnose and remove the employee crisis. In order to achieve the adopted goal, a research question was posed: what determines the increased turnover of employees. The article is a research study. It presents a solution to a specific problem in the examined company. In order to gain a deeper understanding of the main causes of employee turnover, a survey was conducted among employees. The survey covered 1000 respondents. The study is in line with the authors' scientific interests in reporting. Design/methodology/approach: The applied research methods are based on the study of the literature in the field of study and the analysis of non-financial reports in order to identify the reported employee issues in the examined company and the conducted surveys in order to resolve the employee conflict. Findings: The article presents a solution to a specific problem in the examined company. In order to gain a deeper understanding of the main causes of employee turnover, a survey was conducted among employees. The survey covered 1000 respondents. Originality/value: The constant evolutionary processes taking place in the economy stimulate economic, as well as social and environmental development, thus requiring the adaptation of enterprises' communication channels with the market environment. Information presented in a traditional way by financial reporting no longer meets the expectations of potential investors and broadly understood stakeholders who want to base their decisions on the full picture of the situation affecting a given company. This possibility is provided by combining financial issues with non-financial information, and there are still no uniform patterns in the literature regarding non-financial reporting. The implementation of Corporate governance is to secure the interests of the owner and the capital invested in the company, as well as the interests of other stakeholders. A very important additional non-financial information from the point of view of corporate governance is information on the employee area, reporting of which in non-financial statements is still insufficient. There is also little information on resolving employee conflicts. Key words: CSR, corporate governance, non-financial reports, employee issues. Category of the paper: Research paper.
