Modular technology of corporate formation of blue-collar workers’ professional competency

Topicality of the problem under investigation is conditioned by implementation of competency oriented federal state educational standards and professional standards into the practice of blue-collar workers training, the mentioned standards being intended to disclose the host of functions of various blue-collar occupations and WorldSkills standards reflecting modern world trends in the field of formation and development of blue-collar workers’ professional competences. In the meaningful aspect, today’s standards identifying requirements to blue-collar workers training will define principles of selection and formation of competency oriented subject matter of training; however, the choice of training technologies quite often remains beyond the training standards. At the same time, the competency oriented training of blue-collar workers shall envisage application of the activity approach to organization and realization of the training and, consequently, of technologies of training based on the activity approach. The modular technology of training based on points of European concept of “Modular employable skills” can be one of such technologies. The purpose of the article is description of the authors’ modular technology of forming of workers’ professional competency under conditions of corporate training. The modular technology is described herein as exemplified by formation of professional competency of workers of the machine-building industry in field of lathe part machining. The article also includes results of an experimental approbation of a developed modular technology in conditions of plants’ training centers. The investigation’s leading method shall be a pedagogical educational experiment in process whereof the modular technology of forming of workers’ professional competency which has been developed by the authors shall be approbated, the mentioned workers belonging to the machine-building industry in field of lathe part machining, whereas a worker’s professional competency is regarded as an integrated aggregate of core competencies and occupational personal properties which lie in the base of the selection and structuring of the subject matter of training. Materials and methods: the pedagogical educational experiment allows exposing the efficiency of complex formation of the professional competency in trainees by means of applying of the modular technique of training and methodological support, that is, educational elements developed in line with requirements of Modular employable skills concept and supplemented with a set of production tasks performed directly on the job under the tutor’s guidance. The following methods were used in process of the research: theoretical (analysis, synthesis, deduction and induction); diagnostic (methods of analysis and systemizing of scientific pedagogical literature; generalization and classification); empirical (modelling). The key results described in the article: the professional competency model of the machine-building industry workers; the modular technology of forming of professional competency of the machine-building industry workers; the methodological support elaborated in line with requirements of Modular employable skills concept, plus results of the experimental approbation of the developed modular technology. The modular approach, possessing systemic properties, allows integrating the substantive basis of training formed in the competency-based format, processes of selection and structuring of the content of blue-collar workers’ training reflected in the program documentation fixed forms, educational-methodological documentation represented by training elements, organization- methodological aspects of training, organization and realization of training which are also recorded in documentary form in line with requirements of Modular employable skills concept. © 2018 by the authors

In-hospital outcomes of ST elevation myocardial infarction in post-COVID-19 patients

Aim. To study clinical and anamnestic data, as well as inhospital outcomes in patients with ST elevation myocardial infarction (STEMI) with prior coronavirus disease 2019 (COVID-19) compared with previously uninfected STEMI patients.Material and methods. This prospective study included 181 patients treated for STEMI. The patients were divided into 2 groups, depending on the anti-SARS-CoV-2 IgG titer as follows: the main group included 62 seropositive patients, while the control group — 119 seronegative patients without prior COVID-19. Anamnesis, clinical and paraclinical examination, including electrocardiography, echocardiography, coronary angiography, were performed. Mortality and incidence of STEMI complications at the hospital stage were analyzed.Results. The mean age of the patients was 62,6±12,3 years. The vast majority were men (69,1% (n=125)). The median time from the onset of COVID-19 manifestations to STEMI was 60,00 [45,00; 83,00] days. According to, the patients of both groups were comparable the severity of circulatory failure (p>0,05). Coronary angiography found that in patients of the main group, Thrombolysis In Myocardial Infarction (TIMI) score of 0-1 in the infarct-related artery was recorded much less frequently (62,9% (n=39) vs, 77,3% (n=92), p=0,0397). Patients of the main group demonstrated a lower concentration of leukocytes (9,30*109/l [7,80; 11,40] vs 10,70*109/l [8,40; 14,00], p=0,0065), higher levels of C-reactive protein (21,5 mg/L [9,1; 55,8] vs 10,2 mg/L [5,1; 20,5], p=0,0002) and troponin I (9,6 ng/mL [2,2; 26,0] vs 7,6 ng/mL [2,2; 11,5], p=0,0486). Lethal outcome was recorded in 6,5% (n=4) of cases in the main group and 8,4% (n=10) in the control group (p=0,6409). Both groups were comparable in terms of the incidence of complications (recurrent myocardial infarction, ventricular fibrillation, complete atrioventricular block, stroke, gastrointestinal bleeding) during hospitalization (p>0,05).Conclusion. Patients with STEMI after COVID-19, despite a more burdened history and higher levels of C-reactive protein and troponin I, compared with STEMI patients without COVID-19, did not differ significantly in clinical status, morbidity, and inhospital mortality

The Need for the Retina’s Surface “Drying” during Macular Hole Surgery

Purpose: to determine the relevance of retina’s surface “drying” during vitrectomy at the stage of exchange of infusion solution for air based on an experimental study and calculation of the geometric dimensions of a drop of moisture formed in the macular region.Patients and Methods. There were 10 patients (10 eyes), who had a vitrectomy for a macular tear with air injection in one eye. Their age was from 50 to 78 (64.0 ± 3.1), the size of the macular tear 250–631 (431.6 ± 44.3) mkm. After 27G subtotal vitrectomy intake of fluid formed after fluid-air exchange was performed and its volume was measured in equal time intervals 3 times. The next step is to determine the shape of a drop of intraocular fluid (IOF) that forms on the surface of the retina during BSS exchange. For example, in the cadaveric eye, the wetting of the retinal surface was studied with the volume of liquid that was obtained during the operation, and its edge wetting angle was measured. Given the fact that INFLOW during surgery formed from two sources: the result of the production of the ciliary body (CB) (2,5–4,0 μl/min) and dehydration of the vitreous body (VB) due to the pressure of the air supplied in the vitreal cavity was calculated drop diameter INFLOW first, when the product of TST and dehydration VB (CB + VB); second, only if the production CT. This made it possible to understand how a drop of HGH formed during the operation will be projected onto the surface of the macula. Results. Volume of intraocular fluid taken during surgery was 60–80 microliters (68.1 ± 2.8) for 3 minutes, or 22.7 microliters per minute. Rate of fluid formation decreased by 18–25 % for 9 minutes. Contact angle of wetting made 14.5°. Drop diameter calculated for ciliary body secretion and vitreous remnants dehydration equals 17.98 mm. Drop diameter calculated for ciliary body secretion alone equals 2.6 mm. Conclusions. “Drying” of the retina during macular hole surgery is impractical as intraocular fluid is constantly formed on the retina surface. Its volume is sufficient to cause opening of the hole. Refusal from this manipulation would not influence anatomic efficacy of the operation and would reduce surgical trauma
