Probabilistic study of the phenomenon of crushed grains using the model of Weibull
Kheffache Toufik, Melbouci Bachir, 2012, original scientific article

Abstract: The crushing of grains in a granular medium is a very important phenomenon; it is a source of both physical and mechanical changes to these materials. A statistical study of the mechanical properties of a material was used to characterize the distribution and fracture mechanics in order to quantify the evolution of these distributions with sample sizes (grains and whole grains). This work presents the results of an experimental study made on the crushing of individual grains of limestone and samples consisting of multiple grains subjected to a uniaxial loading in order to highlight the influence of the loading and the grain size on the rate of crushing. A statistical study using the Weibull method allowed us to model the problem and quantify the rate of breakage for the two cases. The results obtained show that the rate of deflection depends on the grain size and the intensity of the applied load. Statistical modelling using the Weibull method gave us acceptable results in both cases.

Nationality diversity of bank boards
Miroslav Nedelchev, 2018, original scientific article

Abstract: The aim of this paper is to carry out a comparative study for nationality diversity in bank boards. The study covers practices of board diversity of nine commercial banks. The data are compared for subsidiary banks in Bulgaria and their parent banks from the home country. The study defines a high degree of nationality diversity in subsidiary banks. The Bulgarian banks have a higher number of foreign members on boards compared to their parent banks. The good practices on board diversity in Bulgarian banks are a consequence of their subordination in European financial conglomerates and are aimed to reduce agent conflicts.
Keywords: corporate governance, subsidiary banks, Bulgaria, comparative study

The transfer of knowledge in intra-organizational networks
Władzimierz Sroka, Joanna Cygler, Bożena Gajdzik, 2014, original scientific article

Abstract: Background: In today’s business environment, a company is able to maintain its competitive position if it constantly generates knowledge and disseminates this knowledge within the organization, as well as transforms it into new competences. The ability to transfer knowledge becomes one of the key factors in the improvement of a company’s competitive position. This hypothesis is applicable particularly in the case of cooperation within networks, as they are an excellent opportunity for mutual learning between partners. Objectives: The purpose of the paper is to analyse the process of knowledge transfer in intra-organizational networks. Method: Due to the specificity of the research object, the case study method has been chosen. In order to make an in-depth analysis of the case study, we selected a group of several criteria based on the theory which we believe to be fundamental to the effectiveness of knowledge management in networks, and compared them with the situation in the ArcelorMittal Group. Results: Our research show that ArcelorMittal Group has met almost all the criteria of effective knowledge management in its intra-organizational network. Some exceptions, albeit merely to an extent, are mostly the result of historical circumstances, , i.e. the process of growth through acquisitions, and the acquisition of companies at different stages of organizational development, as well as organizational culture. Conclusion: Based on theoretical assumptions, the study analysed in details the components of knowledge management applied by the corporation in question. Therefore this study might be utilised to formulate a refutable hypothesis and verify them on a larger group of companies from different sectors of the economy. The main limitations of the paper are mostly related to the inherent approach therein

Selection criteria for six sigma projects in Slovenian manufacturing companies
Dušan Gošnik, Matej Hohnjec, 2009, original scientific article

Abstract: Researches reveal that successful six sigma implementation is related to proper six sigma project prioritisation and selection. This research is limited to the selection of six sigma projects in some manufacturing companies in Slovenia. The purpose of this study is to identify what criteria are considered for prioritisation and selection of six sigma projects and how six sigma projects are selected. A research sample is limited by the number of companies which have implemented six sigma so far. The results indicate that Slovenian manufacturing organisations tend to select six sigma projects based on criteria such as customer satisfaction, connection with a business strategy financial benefits, and growth of the organisation. Several tools and techniques such as quality cost analysis, brainstorming and interviews are used to identify and prioritise projects. Identification of the most commonly used criteria to select six sigma projects can help practitioners to select projects based on multiple criteria by using tools and techniques identified in this study. This topic has not been applied in the field of Slovenian manufacturing companies and thus it presents the first study in this field in Slovenia.

Industry 4.0 and the new simulation modelling paradigm
Blaž Rodič, 2017, original scientific article

Abstract: Background and Purpose: The aim of this paper is to present the influence of Industry 4.0 on the development of the new simulation modelling paradigm, embodied by the Digital Twin concept, and examine the adoption of the new paradigm via a multiple case study involving real-life R&D cases involving academia and industry. Design: We introduce the Industry 4.0 paradigm, presents its background, current state of development and its influence on the development of the simulation modelling paradigm. Further, we present the multiple case study methodology and examine several research and development projects involving automated industrial process modelling, presented in recent scientific publications and conclude with lessons learned. Results: We present the research problems and main results from five individual cases of adoption of the new simulation modelling paradigm. Main lesson learned is that while the new simulation modelling paradigm is being adopted by big companies and SMEs, there are significant differences depending on company size in problems that they face, and the methodologies and technologies they use to overcome the issues. Conclusion: While the examined cases indicate the acceptance of the new simulation modelling paradigm in the industrial and scientific communities, its adoption in academic environment requires close cooperation with industry partners and diversification of knowledge of researchers in order to build integrated, multi-level models of cyber-physical systems. As shown by the presented cases, lack of tools is not a problem, as the current generation of general purpose simulation modelling tools offers adequate integration options.

A best practice model for useful suggestions management
Igor Prodan, Branka Ahlin, 2008, original scientific article

Abstract: This paper presents the results of a research project financed by the Chamber of commerce and industry of Slovenia. The main purpose of the project was to propose a model for useful suggestions management, including concrete suggestions for businesses. This is based on (a) an in-depth literature review, (b) case studies of three innovative, export orientated Slovenian companies and (c) the results of the implementation of this model in two Slovenian companies (as a pilot project). Concrete suggestions for businesses regarding the useful suggestions management process, the implementation itself, the rewarding and monitoring of useful suggestions activity and potential adaptations of the model to changes within the company are presented. Since the paper focuses on the implementation of useful suggestions management, offering a rich insight into the concrete processes involved in both developing such policies and carrying them out, companies may achieve great business value by implementing this proposed model.

ICT-supported language learning tools for Chinese as a foreign language
Tina Čok, 2016, review article

Abstract: The paper presents a meta-analysis of 37 scientific papers dealing with the use and adoption of ICT for learning and teaching Chinese as a foreign language. It has shown that systematic content reviews providing overall insight into the nature and level of development in the field are rare. The author tries to fill this content gap by answering three research questions: 1) What is the overall state of research in the field of ICT-assisted learning of CFL in terms of language teaching methods? 2) Which learning technologies are in use for the specific teaching and learning methods for Chinese as a foreign language? 3) Are some learning technologies used more often for practising specific language skills than others?
Keywords: Chinese as a second language, foreign language study and teaching, didactics, ICT-supported language tools, computer assisted language learning (CALL)

Determination of topiramate in human plasma using liquid chromatography tandem mass spectrometry
Tanja Vnučec, Lea Cvitkovič-Maričič, Helena Prosen, Darinka Brodnjak-Vončina, 2013, original scientific article

Abstract: The LC-MS/MS method for determination of the anti-epileptic drug topiramate (TPM) in human plasma was developed and validated for pharmacokinetic and bioequivalence study purposes. For quantitative determination of TPM values the method with deuterated internal standard (topiramate-d12) and liquid chromatography with tandem mass spectrometry was used. TPM was extracted from the human plasma using the solid-phase extraction procedure on a Strata X extraction column. Negative ions were monitored in the selected reaction monitoring mode (SRM) and transitions m/z 338.2 > 78.2 and m/z 350.3 > 78.2 were used for the quantitative evaluation of TPM and the internal standard, respectively. The results obtained from validation were statistically evaluated according to the requirements of European Medicines Agency (EMA) and Food and Drug Administration (FDA) regulatory guidelines. The linearity of the method was checked within a concentration range from 10 to 2000 ng/mL. Successful validation confirmed that this method is precise, accurate, sensitive and therefore suitable for determination of topiramate plasma levels in pharmacokinetic and bioequivalence studies.
Keywords: topiramate, liquid chromatography tandem mass spectroscopy, human plasma, bioequivalence study
