Opis:: Operation in the cyberspace of every business unit is unavoidable. Most commercial transactions, marketing activities, e-mail contact with employees or contractors are carried out using virtual space. The purpose of the article is to identify and analyze selected costs for cybersecurity of an enterprise. Costs related to cybersecurity constitute a new category in the management of an enterprise. Considering the costs at the enterprise level, two areas should be discussed: on the one hand, those incurred to prevent cyber threats and on the other one, the costs of offsetting the negative effects of cyber-attacks. For the sake of stable operation and at the same time development in the future, the management should strengthen activities in the field of information security, which is related to costs that will minimize the risk of cyber-attacks.

Opis:: Cybercriminals during the COVID-19 coronavirus pandemic have redefined both their targets and the form of their cyberattacks. The increased dependence of people around the world on the Internet is driving increasingly bold hacking attacks. Business unit managers are forced to implement better and better security of data resources, which should be organized and at the same time characterized by confidentiality, integrity, and availability. The purpose of the article was to identify and analyse the impact of the COVID-19 pandemic on the cyber security of the business entity. In realizing the purpose of the article, the starting point was a theoretical introduction to cybersecurity. Then, based on the Cybercrime: Covid-19 Impact report developed by Interpol, it was indicated that the coronavirus pandemic has a very high impact on the cyber threat panorama. To analyse the actual market situation, the effects of the cyber-attack on CD PROJEKT Capital Group were analysed.

Opis:: Purpose: The changing market conditions in which an economic entity operates requires its executives to choose management support tools, in particular in the area of locating the company's "bottlenecks". The knowledge of the financial situation of an economic entity becomes indispensable in making decisions at both operational and strategic levels. The aim of the article was to indicate that finance management is one of the most important areas in both current and long-term management of the company's operations in a turbulent environment. Design/methodology/approach: CD PROJEKT Group operating on the global video game market, which is one of the most dynamic sectors of the world economy, was selected for research through purposive sampling. The solutions were developed on the basis of the following research methods: analysis of the literature on the subject, case study, analysis of documents. The financial analysis was conducted on the basis of the inductive inference method, consisting in the examination of the details in the first order, followed by generalizing them in the form of conclusions, synthetic assessment and diagnosis. Trend analysis was used to estimate the likelihood of improvement or deterioration of the financial situation. The temporal scope of the research covered in the period of 2017-2021. During the analytical procedure, selected detailed methods were used, which depended on the issues under consideration as well as problems: balance sheet method, comparative method, indicator method, descriptive methods supported by tables and graphs. Findings: The study confirmed that a turbulent environment has a direct impact on the management, functioning and financial performance of the company. Originality/value: The value of the article is in the analysis of the financial situation of CD PROJEKT Group over the five years and indication of the impact of the turbulent environment on the company's operations. The article is addressed to executive staff in order to make them realize the necessity of conducting ongoing financial analysis in order to locate weak areas of activity and properly adjust the strategy to the capabilities and objectives of the company.

Opis:: The geopolitical situation after February 24, 2022 changed rapidly. The issues of globalization and industrial linkages have taken on new importance. Cooperation in supply chains is no longer based solely on cost minimization. The economic aspect was relegated to the background in favor of the availability of raw materials and goods. Against this background, the arms industry is taking on a new dimension and its effectiveness, operational efficiency and innovation become the conditions for maintaining a sense of security within NATO and the European Union. The aim of this article is an attempt to identify the determinants of the armaments industry strategy of the times of war and unrest. The speed of action becomes a determinant of the armaments industry functioning. It is necessary to cooperate with enterprises that were not active in the processes of arms production so far.

Opis:: An important tendency in managerial decisions is the focus on taking into account the law of the community and local communities. Managers, in accordance with the theory of stakeholders, should take into account the needs of various players. We also support for this in the concept of corporate social responsibility, sustainability or creating shared value. The aim of the article is to present the essence of the influence of secondary stakeholders on the creation of the value of defense enterprises resulting from public relations using digitization and socio-economic globalization. The results of the conducted research will allow to confirm the legitimacy of decisions made by defense companies, taking into account the maintenance of social relations, especially in the new communication and information environment.

Opis:: Dementia with Lewy bodies (DLB) is considered to be the second most frequent primary degenerative dementing illness after Alzheimer’s disease. Psychotic symptoms are typical features in DLB patients, and visual hallucinations are the most frequent neuropsychiatric symptoms and have been considered as one of the core features in the clinical diagnostic criteria of DLB. According to literature, spectrum of delusional ideation may be observed in DLB cases. There is a serious problem of misdiagnosis in cases with delusional ideation in DLB cases. The diagnosis of senile psychosis is frequently made duo to visual hallucinations and delusions. Moreover, diagnosis of delusional parasitosis (form of monodelusional disorder, known as Ekbom’s syndrome) must be taken into account during differential diagnosis. Subjects with delusions of being infested with parasites frequently consult many specialists (dermatologists, internists or allergists) and usually reject psychiatric diagnosis and treatment. Unfortunately, there is a limited evidence of the efficacy of specific pharmacologic interventions, but severe sensitivity to typical and atypical antipsychotics in approximately 50% can occur, and improvements in visual hallucinations with cholinesterase inhibitors could be expected. Herein, we report two cases of DLB suffering due to delusions of being infested by parasites (delusional parasitosis). The paper demonstrates the clinical picture and utility of cholinesterase inhibitors and low doses of second generation antipsychotics in the treatment of psychosis in the DLB cases.
Otępienie z ciałami Lewy’ego (DLB) to druga (po chorobie Alzheimera) przyczyna otępień pierwotnie zwyrodnieniowych. Objawy psychotyczne należą do typowych symptomów DLB, a omamy wzrokowe, najczęstsze w tej grupie objawów, uznano za kluczowy objaw i umieszczono w klinicznych kryteriach diagnostycznych. Jak wynika z piśmiennictwa, u chorych z DLB można zaobserwować całe spektrum treści urojeniowych. Podkreśla się również ryzyko postawienia błędnej diagnozy z powodu treści urojeniowych obecnych u chorych z DLB. Współwystępowanie omamów wzrokowych i urojeń najczęściej skutkuje ustaleniem rozpoznania psychozy starczej. Co więcej, urojeniowa parazytoza (psychoza monosymptomatyczna zwana zespołem Ekboma) powinna być brana pod uwagę w trakcie diagnostyki różnicowej. Ze względu na specyfikę objawów chorzy z urojeniami zakażenia parazytami często zasięgają opinii różnych specjalistów (dermatologów, internistów, alergologów), a odrzucają rozpoznanie psychiatryczne i odmawiają leczenia psychotropowego. Niestety, istnieją jedynie ograniczone dane na temat skuteczności specyficznych interwencji farmakologicznych, a po zastosowaniu neuroleptyku u około 50% chorych z DLB odnotowuje się poważne reakcje nadwrażliwości. Poprawy w zakresie omamów wzrokowych można się spodziewać po włączeniu do leczenia inhibitorów cholinesterazy. W pracy przedstawiono dwa przypadki pacjentek z DLB doświadczających urojeń choroby pasożytniczej (urojeniowa parazytoza). Zaprezentowano obraz kliniczny psychozy oraz przydatność inhibitorów cholinesterazy i małych dawek leków przeciwpsychotycznych w leczeniu psychozy u chorych z DLB.

Opis:: RNAComposer is a fully automated, web-interfaced system for RNA 3D structure prediction, freely available at http://rnacomposer.cs.put.poznan.pl/ and http://rnacomposer.ibch.poznan.pl/. Its main components are: manually curated database of RNA 3D structure elements, highly efficient computational engine and user-friendly web application. In this paper, we demonstrate how the latest additions to the system allow the user to significantly affect the process of 3D model composition on several computational levels. Although in general our method is based on the knowledge of secondary structure topology, currently the RNAComposer offers a choice of six incorporated programs for secondary structure prediction. It also allows to apply a conditional search in the database of 3D structure elements and introduce user-provided elements into the final 3D model. This new functionality contributes to a significant improvement of the predicted 3D model reliability and it facilitates a better model adjustment to the experimental data. This is exemplified based on the RNAComposer application for modelling of the 3D structures of precursors of the miR160 family members.

Opis:: The number of elderly patients undergoing liver transplantation (LT) is increasing worldwide. The aim of the study was to evaluate the impact of recipient age exceeding 60 years on early and long-term outcomes after LT. Material and methods. This study comprised data of 786 patients after primary LT performed at a single center between January 2005 and October 2012. Patients over and under 60 years of age were compared with respect to baseline characteristics and outcomes: postoperative mortality (90-day) and 5-year patient (PS) and graft (GS) survival. Associations between recipient age exceeding 60 years and LT results were assessed in multiple Cox regression models. Results. Recipients older than 60 years (n=107; 13.6%) were characterized by more frequent hepatitis C virus infections (p<0.001), malignancies (p<0.001), and cardiovascular comorbidities (p<0.001); less frequent primary sclerosing cholangitis (p=0.002) and Roux-en-Y hepaticojejunostomy (p<0.001); lower Model for End-stage Liver Disease (MELD; p=0.043); and increased donor age (p=0.012). Fiveyear PS of older and younger recipients was 72.7% and 80.6% (p=0.538), while the corresponding rates of GS were 70.3% and 77.5% (p=0.548), respectively. Recipient age exceeding 60 years was not significantly associated with postoperative mortality (p=0.215), PS (p=0.525) and GS (p=0.572) in multivariate analyses. The list of independent predictors comprised MELD (p<0.001) for postoperative mortality; malignancies (p=0.003) and MELD (p<0.001) for PS; and malignancies (p=0.003), MELD (p<0.001) and donor age (p=0.017) for GS. Conclusions. Despite major differences between elderly and young patients, chronological age exceeding 60 years alone should not be considered as a contraindication for LT.
