No full textDear readers,
let me greet you in this challenging times. Lockdown and physical distancing measures in lots of countries required adoption of information and communication technologies (ICT) and people urged to deploy digital technologies to enable as normal life as possible. Governments have designed applications and services to help in the fight against COVID-19, to facilitate wide range of services. In such environment, we have learned that future of ICT related research is in interdisciplinary approach and relations with other research domains. That is in the focus of JIOS. Now, more than ever, we will encourage and promote interdisciplinary related information sciences research topics.
In this issue, we are presenting nine original scientific papers dealing with various aspects of information and communication technologies. I believe you will find interesting topics for your research agendas.Hope that many of you who read the Journal will join us as authors.

Comparison of Telecommunication Markets in Europe using Multivariate Statistical Analysis
No full textCommon problem in valuation of telecommunication companies is finding comparable data and markets for valuation. The aim of this work was to identify comparable markets for the telecommunication market in Europe. A method for comparison of the markets based on the Multivariate Statistical Analysis was presented. The study covers twenty-two European countries. Using taxonomic measures, these countries were divided into five groups, taking into account the following variables: average monthly service cost of the fixed Internet, average cost of the mobile usage, and average cost of the fixed telephony usage. Within individual groups, the costs of telecommunications services are less diverse than in the entire population; their members can be considered comparable markets. The same method can be used for comparing markets in cases of enterprise valuations in the telecommunication sector, and also in analysis of their level of development
Education Systems as Contextual Factors in the Technological Pedagogical Content Knowledge Framework
No full textDigital competences should be considered in teacher education and professional development. The Technological Pedagogical Content Knowledge (TPACK) framework represents the knowledge required by teachers in order to successfully integrate technology into the teaching process. The Survey of Pre-service Teachers’ Knowledge of Teaching and Technology (SPTKTT) is one of the inventories developed to measure the TPACK framework. The aim of this study is to validate the SPTKTT inventory in the context of the Croatian education system by the use of exploratory and confirmatory factor analysis. Results showed that the new context structure of the SPTKTT inventory consists of nine factors, while confirmatory factor analysis established that the two Content Knowledge factors can actually be unified. This can be explained by differing content organization in education systems. There were also differences in the distribution of some of the remaining factors. Internal consistency of the inventory shows high reliability
Abstract-Syntax-Driven Development of Oberon-0 Using YAJCo
No full textYAJCo is a tool for the development of software languages based on an annotated language model. The model is represented by Java classes with annotations defining their mapping to concrete syntax. This approach to language definition enables the abstract syntax to be central point of the development process, instead of concrete syntax. In this paper a case study of Oberon-0 programming language development is presented. The study is based on the LTDA Tool Challenge and showcases details of abstract and concrete syntax definition using YAJCo, as well as implementation of name resolution, type checking, model transformation and code generation. The language was implemented in modular fashion to demonstrate language extension mechanisms supported by YAJCo
Technology Acceptance Model Based Study of Students’ Attitudes Toward Use of Enterprise Resource Planning Solutions
No full textEnterprise Resource Planning (ERP) solutions are the most frequently used software tool in companies in all industries. Therefore, the labour market requires the knowledge and skills for usage of ERP solutions from graduates – future employees. The main objective of our paper is therefore the identification of important factors that contribute to the acceptance of ERP solutions by students in economics and business and that shape their intentions to use this knowledge in the future. The model of our research is based on the Technology Acceptance Model (TAM), extended by identified important multidimensional external factors that refer to (1) students’ personal characteristics and information literacy, (2) perceived system and technological characteristics of ERP solutions and (3) perceived support within the study process. Research results revealed that several dimensions of the three multidimensonal factors play an important role in shaping the attitudes towards acceptance of ERP solutions by students

Forming an Open Structure of Consumer Knowledge: the Case of Lithuanian Beauty and Personal Care Mass Product Industry
No full textPurpose of the article. Scientific research implies that current tectonic shifts, taking place in the external environment, have been reforming the consumer market. In the context of these tendencies, the knowledge seeded in consumer’s consciousness keeps fluctuating in the direction hard to identify. The article investigates the problem of how the dynamicity of consumer knowledge manifests itself.
Scientific aim: The present paper aims at suggesting guidelines for constructing an open structure of consumer knowledge.
Findings. In grounding the object of the current article, theoretical investigation has been carried out to reveal that consumer knowledge dynamicity is the change of product-related information and subjective experiences, stored in consumer’s long-term memory and allowing the consumer to make purchasing decisions. It manifests through certain structural parts of knowledge, open to the external environment change and interrelated, dealing with product terminology and attributes, with the evaluation of those attributes and the ways of usage as well as facts about the brand. Those structural parts are influenced by marketing activities of an organization, by macro-environment factors, by consumer characteristics, and by changes in purchasing decision making. The present article introduces the case of Lithuanian beauty and personal care mass product industry.
Conclusions. The overview and analysis of qualitative research results have revealed the following path of the open consumer knowledge structure formation. Consumer’s knowledge about a product is built when the consumer has certain knowledge on product terminology and on product usage ways. The knowledge of product terminology and usage, then, determines the creation of knowledge on product attributes evaluation. The latter knowledge category builds synergy in the interaction with product attributes which, consequently, influence brand facts
Parallel Simulation of Tasks Scheduling and Scheduling Criteria in High-performance Computing Systems
No full textThis work is focused on the issue of job scheduling in a high performance computing systems. The goal is based on the analysis of scheduling models of tasks in grid and cloud, design and implementation of the simulator on the base of GPGPU. The simulator is verified by our own proposed model of job scheduling. The simulator consists of a centralized scheduler that is using GPGPU to process large amounts of data by parallel way. In order to ensure the optimization of the scheduling process we have implemented a simulated annealing algorithm. GPGPU model was compared to the CPU when the number of nodes from 32 to 2048. Improving the implementation based on GPGPU had a significant impact on the system with 512 nodes and with an increasing number of nodes further accelerates in comparison with sequential algorithm. In this work are designed new scheduling criteria which are experimentally evaluated
