The research presented in this paper is part of a larger project concerning knowledge risks that can manifest alongside knowledge processes within organizations. The aim of this paper is to reveal the most important scientific evolutions in the field of Knowledge risks, considered as a narrow field within the bigger field of Knowledge management. The methodological approach is based on the use of the bibliometric software R-Stata Bibliometrix, specialized in Science Mapping Workflow, in order to extract meaningful results about the thematic evolution of the Knowledge risks field. The methodological approach assumes that the co-occurrence of two keywords within the same article indicates a link between those topics. Our results show that “knowledge risks” is a very specialized area, but with an important transversality. The concept of “knowledge risk” often appears as a secondary concept in research published in various fields, the publications within the field of Knowledge management being a minority in the total publications where the concept is found. The main novelty of our research consists in a mixed approach, both quantitative and qualitative, of the bibliometric analysis, using bigrams to understand the evolution of this particular scientific field. The results are important for improving the design of future scientific research on knowledge risks.

In the contemporary landscape of global challenges and uncertainties, the significance of national resilience stands as a cornerstone for a country's ability to effectively respond to crises, maintain stability, and secure the well-being of its citizens. This study sought to assess the resilience levels of European Union (EU) countries in the aftermath of the Covid-19 crisis, through the analysis of secondary data. The investigation incorporated the FM Global Resilience Index, comprising three key indicators—economic resilience, risk quality, and supply chain resilience. To achieve the research objectives, a Two-Step Cluster Analysis and One-Way ANOVA were conducted using the SPSS statistical software. The study outcomes delineated three clusters characterizing the resilience levels of European Union countries. Notably, Denmark emerged as the most resilient country, succeeded by Luxembourg and Germany. Romania, in this context, occupies the 22nd position in the ranking. The study's implications go beyond shaping post-Covid-19 resilience policies in European Union countries, and also provide valuable insights for the specialized literature on the subject. This dual impact underscores the study's significance in both practical policymaking and academic discourse

There is a vast body of literature in the economics and business academia investigating if the presence and development of clusters of related industries and complementors in the regional or local economy drive the firm or regional performance. Despite the high enthusiasm with which the businesses and policy makers embraced the cluster theory recently appeared also some contradicting evidence regarding the pure effect of participation of firms in this type of geographical bounded collaborative strategies and firm performance. In this paper, relying on empirical evidence provided from inside the firm by experienced managers we found relatively weak support for some aspects of cluster theory. Through a statistical analysis of the answers provided by 65 medium and large companies operating in the manufacturing sector in Romania we provide evidence of a relatively weak effect of presence of related industries and complementors in the local economy and productivity related performances (revenues, profits, labor productivity, customer satisfaction, organizational growth) and no relationship with innovation related performances (new product development, products and processes/operations improvement, diversification, market expansion). The findings from our paper contribute to the stream of research and theories which prioritize for the achievement of superior performances, what happens inside the firm, what the firm and company centric strategies, rather than the contextual conditions such as the presence and participation in local clusters.

Numerous organizational cultures, as well as MBA and PhD programs, have emerged in the realm of ethics. However, the question arises: can we truly embody these ethical ideals in our actions? Is it imperative enough to be an integral part of a company's strategic vision? Should it find its place in the employee handbook or be woven into job descriptions? In a landscape teeming with diverse ethical and moral perspectives, many individuals employing these terms may actually mean something quite distinct from one another. When an organization meticulously fine-tunes its relationship with competitors, ethics can emerge as a potent competitive advantage. This article subscribes to the idea that ethics, morality, and integrity should serve as the fundamental guiding principles for long-term evolution, and it offers a concise set of methodologies for ensuring their enduring preservation.

Authors: Matope Samson , Kwabla Senye-Awudi Patrick
Published: May 2024

This quantitative study sought to explore how Strategy Instructions Approach (SIA) as reading comprehension technique can help develop positive attitudes in learners towards reading. This study was necessitated by the fact that most South African children do not have positive attitudes towards reading and, as such, are not motivated to do reading on their own. To develop a positive attitude towards reading, learners must acquire a rich vocabulary. To acquire a rich vocabulary, learners must be acquainted with the strategies required for decoding meaning from texts. Researchers revealed that English First Additional Language teachers do not have adequate skills to teach learners to effectively comprehend what they read. This study used SIA, which was found to be an effective way of teaching reading comprehension, to grade 8 learners in Elliotdale Circuit Management Centre (CMC) in the Amathole East District of the Eastern Cape of the Republic of South Africa. The aim of this study was to find out if SIA could be used to develop positive attitudes in the learners towards reading. Sixty learners were sampled from three schools, twenty per school, to take part in the study. The Statistical Package for Social Sciences (SPSS) was used to analyse the data. Descriptive statistics were used to summarize and describe the data collected before and after the interventions. The study revealed that the use of SIA to teach reading comprehension developed positive attitudes of the learner participants towards reading. The study also recommends that school-based staff induction programs should equip teachers on how to use SIA as a strategy for reading comprehension. Teacher training should also equip pre-service teachers on SIA and other reading comprehension strategies.

Published: May 2024

UNUD GDLN building located in UNUD Sudirman campus acts as an information and communication technology service center as an internet access service provider, radio broadcast and online learning. The UNUD Campus network currently uses a static hybrid routing protocol, where the static routing protocol has the disadvantage that the network administrator must always reconfigure the network if there is a topology change. The Open Shortest Path First (OSPF) dynamic routing protocol can be used as a solution to overcome the weaknesses of static routing protocols because it is more suitable for larger networks and has the advantage of automatically determining the best route. This research aims to analyze the application of OSPF routing protocol in UNUD Denpasar Campus with GNS3 simulation. This research uses Quality of Service (QoS) parameters to analyze network performance, and test scenarios by PING with large data transmission that imitates YouTube video streaming. The results showed that OSPF dynamic routing protocol has better performance and has met the TIPHON standard with very good results for packet loss, throughput, and delay parameters and good results for jitter parameters. Tests on static routing protocol simulations and OSPF routing protocols are carried out by comparing the transmission process based on the resolution on YouTube video streaming imitation, starting with 360p, 480p, 720p and 1080p resolutions. Based on the results of the study, it can be concluded that OSPF routing is more suitable and produces better parameter values when transmitting streaming video with a resolution of 480p, 720p and 1080p, while the transmission of streaming video with a resolution of 360p is more suitable for static routing which is more suitable for transmission with lower resolutions.

The high frequency of prevalence and the decrease in the quality of life of patients determine the urgency of studying the peculiarities of the etiology and pathogenesis of inflammatory bowel diseases. The difficulty of finding new non-invasive markers lies in the lack of a clear understanding of the molecular mechanisms of the pathogenesis of these diseases. One of the promising directions in the diagnosis of chronic inflammatory diseases is the identification of specific miRNA molecules in blood serum, which act as powerful negative regulators of gene expression.

In this research, the combustion properties of the briquette produced by blending mung beans shell (MBS) with carbonized danta wood sawdust was compared with that of the briquette produced by blending MBS with uncarbonized danta wood sawdust. The briquettes wereproduced atdifferentsawdust to biomass ratios (100%:0, 70%:30%, 50%: 50%, 30%: 70% and 100%:0). Cassava starch was used as a binder. Proximate analysis (moisture content, ash content, volatile matter and fixed carbon) and combustion properties (calorific value, ignition time, burning time, burning rate, specific fuel consumption and thermal efficiency) were calculated using standard methods. The results of the analyses showed that 100% sawdust briquette samples had the lowest moisture content, 4.74±0.00 for carbonized sawdust and 6.76±0.02 for uncarbonized sawdust.100% uncarbonized and carbonized sawdust briquette samples had a fixed carbon of 68.93±0.02 and 87.46%, Ash content:3.70±0.00% and 2.18±0.04%,volatile matter: 20.61±0.00 and 5.61±0.04 and calorific value: 29.401±0.0 MJ/Kg and 32.532±0.05 MJ/Kg respectively.The ignition time increase with increase in biomass load for uncarbonized sawdust samples and decrease with increase in biomass load for carbonized sawdust briquette samples. The burning time decreased from 86±0.57mins (70% sawdust + 30% biomass) to 70±0.57mins (100% biomass) for the carbonized sawdust briquette samples and for the uncarbonized, it ranged from 68±0.00 (70% sawdust + 30% biomass) to 71.6±0.57 mins (30% sawdust + 70% biomass) and then dropped to 68±0.57(100% biomass load). The burning rate decreased in carbonizedbriquette samples and increased in uncarbonized briquette samples with increase in biomass load. The specific fuel consumption for carbonized and uncarbonized sawdust briquette sample decreased with increase in MBS load. 100% carbonized and uncarbonized sawdust briquette samples had a thermal efficiency of 8.78 and 16.47 respectively. It can be concluded that blend of carbonized sawdust and mung beans shell will make a better fuel due to better combustion properties than the uncarbonized sawdust samples.

Modern challenges in processing vast amounts of data are solved with the help of complex distributed systems, which in turn require cyber protection, that has the instruments for managing security riskssuch as information acquisition, espionage, reduction of system productivity, etc. This article provides an overview of some approaches to detecting cyberattacks, which in particular use machine learning. Their advantages, disadvantages, work methods, vulnerabilities, and approaches to their protection are given. Approaches to using various machine learning modelsfor pre-processing input data, which is subsequently analyzed by intrusion detectors, and ways of improving the accuracy and effectiveness of cyberattack identification were also investigated.As a result of the analysis of research, it is shown that there is a need to combine data from various attack detection systems used at different layers of cyber defense. The use of attack detection systems in different layers of the system allows the detection of such attacks as SQL insertion, obtaining administrator rights, acquiring access to the node, DDoS, and Probe. This can be done by analyzing logs, or network packets in case of SQL insertion, or by monitoring Internet traffic during a DDoS attack. Taking into account the growing variety of attacks on distributed systems and the increase in the amount of information being processed, the use of machine learning in attack detection systems is becoming an increasingly attractive direction for study. Artificial intelligence can be involved in selecting the necessary features for analysis, detecting interven-tions, reducing the level of false attack detections, and improving the accuracy of their recognition. The ability to retrainthe model on new data is a significant advantage due to the small number of available test datasets dedicated to attacks on dis-tributed systems. There is a need to investigate the feasibility of using certain machine learning models and neural networks, based on available input data and requirements for accuracy and speed.It has been determined that anomaly detection is the most common approach to recognizing attacks using machine learning in the commercial product market. Analysis of attacks against machine learning-based defenses that use an anomaly detection approach has shown that there are weaknesses that can be minimized with additional protection; for example, time-distributed attacks can adapt to acceptable ranges of deviation of network indicators. An overview of the mechanisms for ensuring the resistance of protection systems tosuch influences, including the addition of various noises during training, range reduction of system parameter values, variations in retraining the model on misleading data, and the use of special classifiers, was performed

It was found that the modification of commercial activated carbon grades F400 and AS-CS with ferric oxide obtained from alumina production waste "red mud" allows increasing the sorption capacity of activated carbon grade F400 to 60.241 mg/g (2 times). At the same time, the maximum sorption capacity of activated carbon AS-CS increases almost 7 times. The content of Fe2O3 fixed in the structure of activated carbon reaches 9.14%. It has been established that the modification forms an additional number of phenolic groups on the surface of the material, which contributes to an increase in the anion exchange capacity of the sorption material by 2.55 times. The sorption material is effective for removing phosphorus compounds from water at the level of 88.1% and can be recommended for use in the treatment of industrial water

The study of microorganisms used in the food industry is necessary to improve the quality of food products. The complex nature of the relationships between members of associations of these microorganisms and the influence of endogenous factors on them should be taken into account in the production of appropriate food products.The impact of endogenous factors on microorganisms used in the food industry determines the composition of their as-sociations, which in turn determines the quality of the resulting product. Therefore, analysis of the formation of such associa-tions is a necessary element of food technology.An analysis of studies andpublications has shown that today the issues related to the formation of microorganism associa-tions used to ensure fermentation processes in food technology have been given insufficient attention in the scientific literature.The purpose of the article isto study the formation of the component composition of lactic acid bacteria and yeasts of different starter cultures depending on the endogenous factors for the differentiation of fermentation products.The formation of microorganism associations in different starter cultures has been studied. In order to conduct research, different types of starter cultures were used to prepare rye-wheat bread, beer, and fermented milk products. The taxonomic com-position of the associations of the studied starter cultureswas analyzed. Endogenous factors that are the main cause of differences in the composition of microorganism associations in different starter cultures have been studied. The significance of the synergism between lactic acid bacteria and yeast for the inhibition of bacteria harmful in food production has been determined.It has been shown that the formation of the composition of microorganisms, first of all, depends on the technology of the starter preparation, its type and the chemical composition of the fermentation substrate. The organoleptic characteristics of the resulting food products were corresponded to the composition of the association of microorganisms of the starter culture thatwas used. The results obtained show that flour starters can be usedto start the fermentation process of sugar-rich substrates
