The virtual reality information system for the ISN LPNU department tours with elements of full immersion as a platform for an open day

Virtual reality is an important information technology that allows to achieve significant progress in underserved areas. Immersive multimedia, or virtual reality, is a software-simulated environment that simulates physical presence in the real or imagined world. Innovative applications such as high-tech intelligent systems that correlate with the information technologies of display, modelling, building and maintaining networks, artificial touch and computer graphics have made virtual reality a breakthrough in the computing world. Excursions and distance learning in virtual reality are one of the ways to simulate the presence in a city in which a person cannot be physically present at the moment. When viewing virtual tours or attending online classes using videos/photos, the user (applicant/student/learner/teacher) only sees a flat image and cannot interact with it. In this way, the effect that the user is present in that place is lost. Virtual reality with the effect of full immersion allows to eliminate these disadvantages almost completely, and to provide the opportunity to interact with objects located on the virtual stage with the help of real body movements. In addition, in a short period of time, with the help of virtual reality, the user can visit many places, literally without leaving home. This is impossible to do in real life, as certain places are located at a great distance from the user. The object of the study is the process of conducting an interactive excursion and distance learning on the basis of the Department of Information Systems and Networks of the Lviv Polytechnic National University in virtual reality. The subject of the study comprises means, methods of designing and developing the virtual reality information system of excursions and distance learning using virtual reality information technologies. The practical significance of the obtained results is the implemented information system for conducting interactive excursions and distance learning on the basis of the university department. The scientific novelty of the obtained results is an information system based on the use of virtual reality, which is intended for online visits to the premises of the university department with elements of full immersion, as a platform for career guidance of students or distance learning of students.

Scientific application of the program is important: its users can be scientists, students and other researchers of innovative methods of investment portfolios formation.

Ways to improve mechanisms for ensuring information security in departmental information and telecommunication systems of the Security Service of Ukraine

Mass creation, implementation and exploitation of information and telecommunication systems, along with great advantages and conveniences, also cause significant dangers. The leakage of information through technical channels, as well as unauthorized access, can cause serious consequences for the security of the country, which is especially relevant in the conditions of Polish aggression against our country. The problem of this issue was found in the "Anti-corruption program of the SSU for 2021–2024", where it is noted that there are such factors as: imperfection of the normative-legal basis for the above issue, insufficient material and technical support, insufficient awareness of SSU colleagues with the requirements of the legislation in the field of document management and information protection with restricted access, significant electronic document flow, insufficient level of control over the organization of modernization of information and telecommunication systems and the construction of their complex information protection systems. The protection of critically important data arrays must comply with international and national regulatory and methodological documents and standards. Currently, high-pressure technical means are used and strictly regulated organizational measures are implemented. However, there is no answer to the most important question – to what extent the writing that is being renewed or developed is really of high-quality and sufficient, what is its planned and actual effectiveness. Within the framework of the coverage of the theoretical and methodological principles of optimization of the construction of secured information and telecommunication systems, an analysis of shortcomings in modern approaches to the construction of complex information protection systems was carried out together with the review and systematization of theoretical and practical recommendations regarding the improvement of mechanisms for ensuring the information protection system; the article analyzed the existing mechanisms of interaction between the components of information security systems for the needs, assessed the general experience of the relevant countries of the world and their associations, as well as NATO and the EU; approaches to the improvement of normative and organizational mechanisms for the protection of information with restricted access in departmental information and telecommunication systems are proposed. Key words: information protection, information and telecommunication systems, automated systems, information security, comprehensive system of information protection, information and computer technologies, cyber security, information activity.

Bitcoins Usage By Cybercriminals – Evolution And Current Mitigating Approaches

Bitcoins Usage By Cybercriminals – Evolution And Current Mitigating Approaches Daniel Tibina Apuri Digital Forensics &amp; Cyber Security Graduate Programme Department Of Information Systems &amp; Innovations Ghana Institute of Management &amp; Public Administration Greenhill, Accra, Ghana E-mail: dapuri@gimpa.edu.gh Phone: +233205967243 ABSTRACT The issue of security is one of the most pressing concerns about the emergence and adoption of cryptocurrencies. There is currently a serious concern regarding the security of blockchain technology. Although cryptocurrencies offer a high level of network security by keeping transactions anonymous, it also raises the possibility of bitcoin being used for illegal reasons. Furthermore, the technology that underpins the operation of a cryptocurrency, like any other information system, is vulnerable to many forms of attacks. A connection where bitcoin is traded for traditional money is a weak spot in the cryptocurrency circulation chain. Because this occurs on newly unregulated exchanges, they are frequently targeted by hackers. Other dangers exist in the bitcoin industry. For example, with the fast appearance of new cryptocurrency exchanges, determining their previous performance and just hoping for their dependability becomes challenging. There are "grey" stock exchanges, which can halt operations at any time after withdrawing assets. The potential of a cryptocurrency to launder money or support terrorists is the most serious security concern for many nations. To combat money laundering, the Japanese government, finance ministers, and chiefs of central banks in France and Germany have proposed making cryptocurrency regulation international. The IMF also believes that worldwide regulatory oversight of the digital currency sector is required.

Data were obtained from Hospital Information System (HIS) and microbiology department records. The risk factors for mortality and acquiring MDR, ESBLs-producing and CR GNBSI were analyzed by univariable and multivariable analysis.ResultsA total of 1018 GNBSI cases were collected. A majority of GNBSI patients were in hematology ward (23.77%). There were 38.61% patients who were assigned in the 41–60 age group. Escherichia coli was the most common gram-negative organism (49.90%). Among isolates of GNBSI, 40.47% were found to be MDR strains, 34.09% were found to be ESBLs-producing strains and 7.06% were found to be CR strains. Escherichia coli was the most common MDR (71.36%) and ESBLs-producing strain (77.81%). Acinetobacter baumannii was the most common CR isolate (46.15%). Multivariate analysis indicated that diabetes mellitus, solid organ tumor, non-fermentative bacteria, MDR strain, central venous cannula, urinary catheter, therapy with carbapenems or tigecycline prior 30 days of infection were independent mortality risk factors for GNBSIs. Over all, therapy with tigecycline prior 30 days of infection was the mutual predictor for mortality of GNBSI, acquiring MDR, ESBLs-producing and CR GNBSI (OR, 8.221, OR, 3.963, OR, 3.588, OR, 9.222, respectively, all p < 0.001).ConclusionCollectively, our study implies that patients who were diagnosed as GNBSI had a younger age. Therapy with tigecycline was the mutual and paramount predictor for mortality of GNBSI, acquiring MDR, ESBLs-producing and CR GNBSI. Our investigation had provided a theoretical basis for the use of antibiotics and prevention and control of hospital infection in our region.
