Annotation. The global pandemic has necessitated the development of new respiratory protective equipment that seems to combine reliability and ergonomics. The article tests an innovative conceptual model of a pneumatic helmet with a laminar air supply system for its permeability to bacteria Micrococcus luteus and antistaphylococcal bacteriophages. The latter were fed in the form of an aerosol to the external filter of the working device with subsequent titration and seeding. Evaluation of bacterial infection is performed by counting the units that form colonies by multiplying the above indicator by the degree of dilution. The presence of bacteriophages and their number was determined by the Grace method with the calculation of plaque-forming units in the culture of Staphylococcus aureus. Statistical processing of the results was performed on a personal computer Intel Core i3 using one- and multi-factor analysis of variance (licensed software packages Microsoft Office 2016 and Statistica 10). In the full and partial configuration of the device (if there is only an external or internal filter), the penetration of microorganisms into the internal space is not detected. The results of the study confirmed the reliability of the protection system for 6 hours of continuous operation, which makes the conceptual model of a pneumatic helmet a more ergonomic alternative to the usual means of respiratory protection.

Abstract:Many clinics are interested to use software packages in daily practice, but lack of integration of such packages seriously limits their scope. In practice this often entails switching between programs and interrupting the run of an individual program. A multi-task approach would not solve this problem as it would not eliminate the need to input the same data many times, as often occurs when using separate packages. The construction of a Multi-Service Medical Software package (MSx2) is described, which was also developed as an example of practical integration of some clinically relevant functions. The package runs on a personal computer in an MS-DOS environment and integrates a time-oriented medical record management unit (TOMRU) for data of ambulatory patients, and a drug information management unit (DIMU) concerning posology, content, effects, and possible interactions. Of the possible database configurations allowed by MSx2, the cardiology patient database (MSx2/C) and hypertensive patient database (MSx2/H) were developed and described here. Clinical information to be included in the configurations was obtained after discussion and consensus of clinical practitioners. MSx2/C was distributed to several hundred clinical centers during computerized courses to train future users. MSx2 can easily transfer patient data to statistical processing packages.

This contribution argues for the relevancy of software literacy as part of understanding the ways people engage with software and how its affordances influences knowledge representation, generation and critique. It will define the term and set out three progressive tiers of development towards software literacy.

The aim of the study – improvement of pregnancy outcomes in women with pelvic presentation on the background of uterine myoma by developing optimal obstetric delivery tactics. Materials and Methods. In order to achieve the stated goal, a prospective analysis of cases of first- and second-time delivering patients with full-term one fetus pregnancy in pelvic presentation (incomplete and complete) amid the uterine myoma – the main group (MG) – (n = 30) was conducted. Into the control group (CG) – (n = 30) were included the first- and second-time bearing women without fetal myoma with full-time pregnancy and the pelvic presentation. Statistical processing of the results was performed using the Microsoft Office Excel 2017 software. Results and Discussion. The analysis of the presented data shows that among pregnant women with pelvic prevalence of fetuses on the background of uterine fibroids, more frequent cases are registered: clinical manifestations of the threat of interruption of pregnancy MG – 26 (86.7 %), CG – 9 (30 %) and pre-eclampsia MG – 8 (26.7 %), CG – 3 (10 %) (p < 0.05). Raising the risk of complications of pregnancy and the expected birth of the uterine myoma requires pre-planning for the most part the operational method of delivery of MG – 19 (63.3 %). Exception, in the absence of other contraindications, there may be women with single myomatous nodes in sizes up to 5 cm – 11 (36.7 %). Only the extension of the cesarean section requires only pregnant women with uterine myoma 7 (36.8 %), and most of these interventions occur during precarious surgical delivery 4 (20 %). Conclusion. Consequently, the presented data indicate the expediency and validity of taking into account the presence of uterine myoma at BP in order to develop an optimal obstetric tactic for the delivery of such patients in order to improve their pregnancy outcomes.

AbstractCoronavirus disease (COVID-19), the disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, is responsible for the 2020 global pandemic and characterized by high transmissibility and morbidity. Healthcare workers (HCWs) are at risk of contracting COVID-19, and this risk is mitigated through the use of personal protective equipment such as N95 Filtering Facepiece Respirators (FFRs). The high demand for FFRs is not currently met by global supply chains, potentially placing HCWs at increased exposure risk. Effective FFR decontamination modalities exist, which could maintain respiratory protection for HCWs in the midst of the current pandemic, through the decontamination and re-use of FFRs. Here, we present a locally-implemented ultraviolet-C germicidal irradiation (UVGI)-based FFR decontamination pathway, utilizing a home-built UVGI array assembled entirely with previously existing components available at our institution. We provide recommendations on the construction of similar systems, as well as guidance and strategies towards successful institutional implementation of FFR decontamination.

Today, in the global world economic crisis and the Covid / SARS-19 pandemic, the development and functioning of business companies are more relevant than ever. In addition to the global pandemic, the Covid-19 crisis has dealt a devastating blow to the economy and business of the company, and enterprises have suffered severely financially. Development within the framework of proactive management of companies is based on following the required level of their competitiveness. This approach is adapted for business companies and connects together the dynamics of the external and internal business environment, the level of competitiveness of the organization, the level of innovative development, the system of goals of the business organization and the system of goals of business development programs. The conceptual model of content management of the business development program is analyzed, which establishes the compliance of the program objectives with the main factors of the competitiveness of companies and determines the value of projects as ensuring the achievement of these goals, takes into account the possibility of each project’s contribution to the achievement of several goals, as well as the influence of systemic effects in shaping the value of the program and justifying the necessary the amount of resources to provide it. Methods for assessing the values ​​of companies as the degree of compliance of their results with the set business goals. The method is based on the operations and properties of companies, allows to take into account the uncertainty of the conditions and results of the implementation of business companies, forming a two-parameter assessment of the value of the project - the business contribution to the achievement of each goal and the degree of this contribution. This approach, in contrast to the existing ones, makes it possible to take into account the achievement of goals to a greater extent in the following procedures for determining the content of the business. It has been established that synergy in business development programs is manifested in cost savings and an increase in the final value of projects by companies. Authors identified the main sources of the formation of the effect of business synergy associated with costs. Formalized the formation of the synergistic effect in terms of the theory of companies’ projects, arising from the joint implementation of projects within the program, allows with a greater degree of reliability to assess the achievement of the goals of business companies and the necessary resources in conditions of uncertainty.

Protective Effectiveness

The aim of the work was to conduct experimental studies aimed at determining the protection factor of the filter respirator with forced air supply by volunteers in different modes of operation and to establish the dependence of the amount of air supplied by the fan from the air purification device to the filter’s resistance. Simulation studies to determine the protective effectiveness of the filter respirator on the testers were performed according to the procedure for determining the penetration coefficient of test aerosol – sodium chloride, as the ratio of the submask concentration of test aerosol to the ambient concentration formed in a special chamber that meets the requirements of DSTU EN 13274. Determination of the amount of air supplied by the air purification unit to the submask space and assessment of the value of positive pressure inside the mask was performed according to the procedure described in DSTU EN 12941: 2004. As a result of simulated laboratory tests to determine the protective effectiveness of filter respirators with forced air supply to the testers, it was found that the average result of the protection factor of the test samples ranged from 99.93 to 99.97, which meets the requirements of DSTU EN 12941: 2004. In addition, it was found that the amount of air treated by the fan of the air purification device for clean filters is 165 and 215 dm3/min for operating modes “Normal” and “Turbo”, while for the polluted filters it is reduced to 131 and 185 dm3/min, respectively. During the study, the compliance of the value of excess pressure in the submask space with the requirements of DSTU EN 12941: 2004, which should not exceed 2.5 mbar, was confirmed. It is also determined that the stability of the technical parameters of the air purification device is maintained in the specified range when charging the “Dinogy Li-Pol 11000mAh 14.8V 4S 25C” brand battery not less than 12 V to ensure the current value of not less than 1.6 A. The practical value of the results lies in determining the duration of protective action of the filter respirator, the choice of filter resistance to establish the scope and modes of operation in the developed personal respiratory protection equipment.

Objectives of this article refer to ways to increase self-confidence in students from different universities in Transylvania manifested by the values of self-depreciation, infatuation and self-esteem. These are realized through the use of complex exercises on music in the form of dance-therapy and body technique. Purpose: elaboration of an action strategy to modify the self-depreciation, self-esteem, infatuation. Hypothesis: by introducing the exercises of body technique and dance-therapy, the aim is to modify the components of the ASSI psychological test: self-depreciation, infatuation and self-esteem Material and Methods: statistical processing was performed with the program Stats Direct v.2.7.2. The graphical representation of the results was done with the Excel application (from the Microsoft Office 2010 package). The tests used are: ASSI and an intervention program based on exercises in body technique and dance therapy. The subjects participating in the experiment with a duration of 6 months by 200 students at the Technical University Cluj-Napoca, and the extension from Baia-Mare and from the Academy of Music "Gheorghe Dima" from Cluj-Napoca. The period: of development was between October 2019 and March 2020. The results: of this study are due to the intervention program through exercises in body technique and dance therapy performed by the experimental group compared to the control group. In the case of A-SN it is a good correlation but of the opposite direction, which means that if (A) self-depreciation decreases then (SN) self-esteem increases. In the case of I-SN it is an acceptable correlation and of the same meaning, which means that if (I) the infatuation increases and (SN) the self-esteem increases, were observed statistically significantly significant differences between the two times (p <0.001). Conclusions: Statistically significant differences were observed in the indicators of the ASSI tests (self-depreciation, self-esteem, infatuation) which indicates, that our intervention program in the preliminary study had a positive and measurable impact on students in terms of improving self-depreciation and infatuation, as well as increasing self-esteem.
