Opis:
Real-time assessment of IT-related risks, performed at the national level, is very important due to the evolving nature of threats that may originate from individual hackers, organized cyber-criminal groups, as well as state activities. Evaluation of risk that is based on technical information, as well as on mutual relationships between various institutions and services, may result in very valuable situational awareness. The paper describes (in general) cyber risk analysis method which will be implemented in Polish National Cybersecurity Platform.

Opis:
The paper presents a method of assessing of ballistic resistance of four armor steels based on the results of shear tests under dynamic load conditions. All shear tests were performed using a newly developed flat material specimen with two shear zones. High strain-rate experiments were performed using the spilt Hopkinson pressure bar technique. In addition, the V50 ballistic resistance tests for the armor steels were carried out. The maximum value of the shear strain energy density (SSED) was adopted as the evaluation criterion. The SSED parameter takes the highest average value for the armor steel with the highest ballistic resistance.

Opis:
Objectives To assess dietary supplements, functional foods and nutraceuticals use among the patients after myocardial infarction (MI). Material and Methods The authors prospectively enrolled 100 consecutive patients hospitalized due to MI and remaining under coordinated outpatient care after MI in the authors’ cardiology department. Results The authors showed that patients within median (interquartile range) 12.30 (10.18–14.57) months after MI use dietary supplements, nutraceuticals and functional foods in their everyday diet. Vitamins (53% patients), especially vitamin D (35%), were the most frequently used dietary supplements. In contrary to common usage of dietary supplements (59%), smaller proportion of patients use functional foods (21%) and nutraceuticals (5%), especially phytosterols. The authors found that the use of over-the-counter (OTC) drugs and dietary supplements is associated with age (participants <60 years old vs. participants ≥60 years old: OTC drugs: N = 8 [20.0%] vs. N = 32 [53.3%], p < 0.001; herbals: N = 3 [7.5%] vs. N = 16 [26.7%], p = 0.019), sex of the patients following MI (females vs. males: vitamins: N = 17 [70.8%] vs. N = 36 [47,4%], p = 0.045; vitamin D: N = 13 [54.2%] vs. N = 22 [28.9%], p = 0.024; omega-3 fatty acids: N = 3 [12.5%] vs. N = 1 [1.3%], p = 0.042; herbals: N = 8 [33.3%] vs. N = 11[14.5%], p = 0.040), as well as the BMI of the participants (BMI < 24.9 vs. BMI ≥ 25.0: multivitamin/ multimineral dietary supplements: N = 3 [15.0%] vs. N = 31 [42.5%], p = 0.035; vitamin B6: N = 1 [5.0%] vs. N = 21 [28.8%], p = 0.035). In the study group all participants with the age above retirement age have already withdrawn from professional activity and they more often used OTC drugs (N = 14 [25.9%] before retirement age vs. N = 26 [56.5%] above retirement age, p = 0.002). Conclusions The patients following MI use supplements, functional foods and nutraceuticals. Their use depends on sex, age, BMI and professional activity. The authors believe that their potential beneficial effects require further evaluation in clinical longitudinal studies.
