Opis: Purpose: Mobile devices have become an indispensible part of modern communications; they enable easy access to the Internet and also remote manipulation of data stored in corporate information systems. The number of mobile device users is on the rise, but most of them don’t comprehend completely the less obvious functions of these devices. Users also have almost no control over background computer programs, because they run without their knowledge and volition. From the standpoint of information security, a lack of awareness of the risks can seriously compromise the integrity of corporate networks and information systems. The weakest links are users, but also the technology itself. To ensure the functioning and security of information systems, corporations and individual users should learn about protective mechanisms. It is also important that users adhere to implemented (internal) safety regulations. Design/Methods/Approach: We used descriptive and comparative methods, and made an overview of published literature, as well as processes pertaining to the use of mobile devices and related security issues. We compared general elements of information security in regard to the use of mobile devices. Findings: At present mobile devices are more and more frequently used to access information systems. The majority of users are concerned almost exclusively with the question, how to get uninterrupted remote access to data, but far less with security issues. This paper presents some guidelines for achieving and maintaining information security. Research limitations/implications: It has been noted, that this is a time of turbulent development and evolution in the field of mobile devices, and also related security issues, so best practices haven’t been defined yet. Corporations and other organizations have just recently begun defining guidelines to eliminate security breaches through mobile devices, therefore a comparison of their implemented solutions is practically impossible. VS_ Practical implications: We propose guidelines, which can be used to: minimize information security risks posed by mobile devices; evaluate the current state of information security; and implement protective measures against cyber threats encountered by corporations and individual users of mobile devices. Originality/Value: Information security is a relatively new field because mobile devices and remote access to the Internet and data have just recently come into wider use. At the same time security issues and protective measures have stayed largely overlooked. Security threats are many, so it is impervious that users learn more about them and adopt some necessary security measures.

Opis: These general guidelines serve as a supportive document for the glossary for academic integrity (sub-output 3G) that describes the definitions of terms related to academic integrity. They serve to help build common understandings of integrity issues in both academia and business. The guidelines outline minimum requirements and responsibilities of various stakeholders in academia. Many of the guidelines are necessarily general, but, where relevant, we provide country-specific examples as well as adjusting to meet to the needs of different fields of study/research. The general guidelines are addressed to a full range of stakeholders, including national ombudspersons, judicial authorities, compliance officers, research project managers and other related bodies or units in academia (such as policy units, educators/instructors, senior administrator/managers/coordinators) as well as students, the business sector and others.

Opis: The aim of this article is to analyse the most important issues related to the latest forms of online advertising. In particular, appreciating the importance of online advertising in the development of the information society, the question is then raised about the legal limits of the admissibility of advertising, which is invasive, insistent or contains hidden meaning, inaccessible to the recipient's awareness of content. This issue has been presented from the perspective of European Union (EU) law, in the context of selected directives relevant for online advertising. The problem raised in the article deserves to be developed because we observe a sharp increase in the importance of the Internet, and the online advertising issue has not been the subject of comprehensive regulation in EU law.

Opis: The paper deals with structure integrity analysis of the holder for the carrying cross of a washing machine drum. Premature fracture of the holder occurred between mechanical sustainable tests of washing machine in the factory. In order to prevent fracture, the task was to determine the reasons for premature fracture of the holder and to estimate the suitability of the new design of the holder cross. Input data for structure integriry analysis were obtained by material by mechanical testing of used materials. Stress and strain analysis of holder limit load was performed by finite element modeling of holder. Dynamic tests of holders with two different thicknesses were done on a servo-hydraulic machine in order to find dynamical strength and endurance of holder. Fracture behaviour of holders is defined as initiation and propagation of crack. The obtained behaviour confirmed that the new design of holders reduces stress concentration in the critical region. Consequently, the new holder subjected to the same dynamic load can endure a higher number of cycles until breakage. The total number of cycles overcomes industrial testing requirements.

Opis: High-alloyed Cr-Ni-based two-phase stainless steel (SS) cast alloys are commonly used in nuclear power plants. The mechanical equipment in these facilities can contribute to a reduction in its resistance to stable crack growth as a result of extended operating times and high temperatures. The toughness of these materials strongly depends on their delta (▫$/delta$▫) ferrite content, which spinodally decomposes into two phases with different ratios of Cr and Ni at a relatively low (slightly above 300 °C) temperature. This temperature is similar to the operating temperature of the vital parts, for example, the coolant system. The formation of two phases with the same crystalstructure but different lattice parameters causes internal elastic stresses that result in a hardness increase and an impact-toughness decrease. The result is an increased risk of crack formation in the stress-concentration zones such as the critical regions of different welded joints (e.g. "L, T, K and X" shapes). The values of the critical stress intensity factor change according to its position along the crack contour. Therefore, the aim of our study was to assess the influence of the materials' changes on the crack extension and the decrease of the primary pipeline's bearing capacity by taking account of the increased temperature and time of operation for the given loading conditions. The SINTAP (European Structural Integrity Assessment Procedure) was used for this assessment.
