Quality has become an increasingly important and critical success factor at higher education institutions, particularly universities. Numerous discussions have been held about education quality in the context of sustainable development. However, the quality of that education strongly depends on the overall quality of the management system which operates at schools. The principal aim of this article is to present the approaches to the quality management systems’ development and their assessment at universities, and share some lessons learned from this area of research. Some possibilities of the ISO 9001 standard’s implementation, as well as the application of excellence models as a response to community demands, will be discussed, especially in the context of the recently-introduced Act No. 111/1998 Coll on Higher Education Institutions, which requires quality assurance and quality evaluation. A case study from The VSB-Technical University of Ostrava shows approaches, results and effects of the quality management system implementation.

Purpose: The primary purpose of this paper is to identify the most important factors related to the successful implementation of TQM in the literature and to compare the identified factors with the existing research. Methodology/Approach: By conducting a systematic literature review in three main stages, this research analyzes 13 empirical papers published between 1995 and 2017. Three main stages included: formulation of the problem to be solved by the systematic literature review; definition of inclusion criteria and exclusion of articles; and article search and selection. Findings: Analysing previous research and conducting a literature review, we identify six main critical success factors (CSF): top management leadership and commitment, customer focus, training (employees), procurement management (suppliers), information and analysis, and process management. Research Limitation/Implication: In this paper, we focused solely on the influence of TQM practices on the financial performance of a company. As such, the non-financial performance indicators were not considered. Originality/Value of paper: This paper adds value to the existing literature as it focuses on critical factors of TQM implementation examined in relation to the financial performance of the company and provides a good basis for understanding and developing more complex models.

The aim of this study is the evaluation of the parameters of core mixtures using different binder systems with regard to the collapsibility of cores after casting and the resulting product quality of castings reflecting surface requirements based on non-ferrous alloys. The research compares organically bonded core mixtures based on phenol-formaldehyde resins for the production of cores with the shell molding (resin coated sand), currently used in the production of aluminum alloy castings in the Brembo Czech s.r.o., and mixtures using innovative inorganic binder systems based on geopolymers; GEOPOL^® W. The aim of the research is to compare the advantages and disadvantages of these binder systems in order to evaluate the potential of inorganically bonded mixtures to replace organically bonded mixtures, which would lead to a significant reduction in the environmental impacts of industrial production of castings.

In the foundry industry, silica sands are the most commonly used type of sands for the production of sand foundry moulds using various types of binders. Their greatest disadvantage is their significant volume changes at elevated temperatures, which are associated with the formation of many foundry defects from stress, such as veining, and thus have a direct influence on the final quality of the casting. In the case of non-silica sands and synthetic sands, the volume stability is more pronounced, but this is accompanied by a higher purchase price. Therefore, a combination of silica sand and synthetic sand CERABEADS is considered in order to influence and reduce the thermal expansion. The hybrid mixtures of sands, and their most suitable ratios, were evaluated in detail using sieve analysis, log W and cumulative curve of granularity. It was found that the addition of 50% CERABEADS achieves a 32.2% reduction in dilatation but may increase the risk of higher stresses. The measurements showed a significant effect of the granulometric composition of the sand on the resulting thermal expansion, where the choice of grain size and sorting can achieve a significant reduction in dilatation with a small addition of CERABEADS.

The production of cores for the pre-casting of holes in castings places high demands on the quality of the molding mixtures used. For this reason, organic binders are still used to a large extent, which, although they meet the technological requirements, are a source of pollutant emissions during the production of castings. The current trend towards greening production is therefore looking for a suitable alternative in ‘green’ inorganic binders. Although for many decades standard inorganic binders could not be compared with organic resins in terms of technological properties, new inorganic binder systems are currently being developed that can largely eliminate these disadvantages, which include, in particular, significantly lower collapsibility and reclaimability, and lower mechanical strength values. Last but not least, the use of these binder systems may be limited by the technological parameter of shelf-life, which is the main focus of this study. The aim of this paper is to evaluate the influence of technological parameters of core production using a new generation of inorganic binder systems on their shelf-life. Shelf-life, defined as the change in mechanical strength and wear resistance as a function of exposure time in a given environment, is evaluated under different climatic conditions.

The issue of sustainability, or corporate social responsibility (CSR), has become a widely discussed topic in all industrial production sectors. The article focuses on the automobile industrial sector because it is not only the most dynamically developing industrial area but also because it is one of the driving forces of local economies in many European countries. This paper aims to reveal possible differences and diversity of understanding of priorities in the CSR activities provided by automotive suppliers in European countries. Based on the meta-analysis, 73 actions were listed, and a questionnaire survey was performed. Cluster analysis and Fisher’s exact test were applied to find out whether the attitude towards sustainability differs dependent on the position in the supply chain or on the company size.
