Journal of Security and Sustainability Issues

Our paper is dealing with the issues of energy security and economic development. Our focus is on the changes and challenges that are posed in front of the many countries with regard to the threat of the shortages of energy sources and the depletion of the existing carbon sources. Economic, social and demographic changes in the world call for the novel solutions that would include innovative ways how to secure the smooth and undisrupted flow of energy for maintaining the daily lives of the citizens. We are particularly interested in showing how the integration of energy systems or the coordination between neighboring energy systems might contribute to the sustainable development and operation of the energy sector. The paper uses an example of hydro energy storage in order to show the shortcomings of the battery energy storage and the ways how it can be solved. Our results and findings show that renewable energy sources might become a viable solution to the problems specified above. Well-balanced and well-placed usage of renewables might cushion the shortcomings of the traditional energy systems and prevent major shocks to the energy security through the world and in the European Union countries.

The aim of the paper is to analyse the opinion of enterprise representatives upon the risk of errors occurrence in selected areas of accounting. Research presented in this paper explains the view of enterprise accountants upon the risk of errors occurrence, both unintentional and intentional, aimed towards the creation of so called „creative accounting“. The research itself, done on a sample of 232 Czech enterprises, was based on questionnaire investigation which focused on perception of problematic areas influencing the quality of accounting information. The obtained set of data was evaluated using descriptive method and mathematical/inference statistics. Special testing was done at hypotheses on concordance of two mean values and at the Friedman test. Evaluation of problematic rates of individual areas of accounting revealed that practically each observed area of accounting is connected with specific difficulties. The major causes of problems are tax impacts, namely in the area of the cost, time differentiation and of revenues and also difficulty in pricing, especially in the area of inventories and fixed and financial assets. High respondents´ concordance on rating individual accounting areas as to the risk of an error occurrence was detected. It stemmed from the research that the risk of formation of unintentional errors is subjectively rated as the highest in the areas of conjectural and adjusting items and the lowest at asset and depreciation classification. Rating the space for intentional distortion of accounting statements indicates a very reserved attitude of the respondents. The results have proved that in the respondents´ opinion practically all areas of accounting give space for occurrence of errors. The results of the research provided a somewhat different perspective on the issue of accounting errors in comparison with results published by other authors who used objective assessment of error rate as a departure point.

The aim of the article is to suggest a monitoring tool for a business model to assess performance and meet sustainable development goals and indicators for the sea commercial ports. According to the 2030 Sustainable Development Agenda, building resilient infrastructure, promoting inclusive and sustainable industrialization and fostering innovation is one of the seventeen goals set forward. We assume that added value is the key aim of any business model creation, while business model itself is recommended to be based on multidimensional innovation and complementary assets of business.The multidimensional innovations include: market innovation, product innovation and process innovation. The introduction part here presents the description of the business model development roadmap. For the specific case of a trade port case the business model rests on four blocks: the system for added value generation, value suggestion, clients and financial model. The complementary assets’ list is presented for such a sea commercial port. Qualitative and quantitative indicators of the sea trade port business model performance are tracked down. Business model sustainable development for a sea commercial port is described. Value added is considered as the indicator of sustainable development on both micro- and macrolevels.

Since the mid-1990s, enterprise resource plannig (ERP) information systems have been installed in thousands of companies worldwide. A growing number of studies and research papers show that information systems have a significant role in the sustainable economic development assuring economic competitiveness. Modern enterprise performance management shares a strong strategic and sustainable orientation of management focused on further strategic growth and business development with parallel use of information and all highly sophisticated knowledge resulting from modern enterprise information technology. The paper focuses on research findings related to information processes and their impact on overall entrepreneurship performance. The most important results show that the companies from the selected industrial segments in Slovakia have a strong focus on the application of innovation procedures and specific business information systems. The results bring the findings that business intelligence (BI) is based on information and knowledge with a high added value has a positive long-term and sustainable effect on the overall entrepreneurship performance. By application of selected management tools such as ERP, BI information systems and others, it can be achieved a higher entrepreneurship performance of industry companies in Slovakia and EU. We believe that our study presented in this paper contributes to explore a new dimension to the existing view on business information systems in industrial companies. More detailed research results are presented in this paper.
