Aim. The article deals with establishing the effect of step aerobics and artistic gymnastics on physical performance in first year female university students. Materials and methods. 80 full-time ...female university students participated in the study. The first group practiced artistic gymnastics (Group 1, n = 40), the second group (Group 2, n = 40) – step aerobics. The mean age was 18.35 ± 0.04 years. In September and December 2017, their physical development, physical fitness, physical performance, respiratory and cardiovascular systems were assessed based on standard procedures using the data of maximum oxygen consumption and the step test. Results. At the beginning of the experiments, there were no statistically significant differences between Group 1 and Group 2. The mean maximum oxygen consumption values corresponded to satisfactory performance (39.85 ± 0.37 – Group 1, 38.92 ± 0.42 – Group 2, р = 0.1). At the end of the experiment, there were statistically significant differences in terms of the mean maximum oxygen consumption: 40.73 ± 0.21 – Group 1 and 41.61 ± 0.21 – Group 2. The results of the ranking showed that the majority of participants demonstrated an increase in physical performance. Group 1 showed an increase in the standing long jump, Group 2 improved 2000 m running time and the standing long jump. Group 2 also demonstrated a decrease in heart rate and an increase in adaptation capacities. Conclusion. The lessons of artistic gymnastics during a semester do not influence significantly physical performance but improve speed-strength characteristics. Step aerobics influences positively physical performance, speed-strength characteristics, and the cardiovascular system in first-year female university students not related to sport.
The special importance is gained by questions of stability of the Russian economy. Strengthening of this stability in the conditions of information revolution was resulted in need of transition from ..."material" to the "intellectual" economy which is based on knowledge (knowledge based economy). In this regard a problem of formation of competences of the sphere of the higher education receives a priority by preparation of the engineering and scientific shots creating the main part of profit. The article deals with the quality of service in the libraries of the university. We propose the automated system of models of management of information resource, consisting of three complexes, allowing to simulate the process of care, foresee the results of management decisions taken and choose the best of them. The complex of economic-mathematical models of quality management of service is presented in a natation of UML. Proposed economic and mathematical models for assessing the quality of decisions. The process of calculating the ratio of the qualification level of staff and the corresponding service time is shown.
The topic of low-power nuclear power plants has been relevant for more than 50 years. They allow you to conduct electrical energy in remote areas, such as, for example, the Arctic, and to build ...stations with the possibility of mobile regulation in cases of emergency. Currently, the state corporation Rosatom has launched a broad propaganda about the prospects of these nuclear power plants and has stepped up the construction of the first floating nuclear thermal power plant, which is one of the variants of this type of nuclear power plants. The idea of creating this project has generated a mass of protests from environmental organizations. In this paper, the scenario of a beyond design basis accident at a floating nuclear power plant is considered. Calculation of the damaging factors of this accident. The calculation of prevented damage was made using the existing methodology with some changes made for convenience of calculation, and a formula was introduced for comparing the costs of measures to prevent damage with the magnitude of this damage. The improved methodology can be used in the EMERCOM of Russia system for forecasting emergencies at the facility level. The introduction of this methodology and its practical application for the assessment of prevented damage will make it possible to predict the consequences of the occurrence of emergency situations on energy-saturated objects, objects with a massive presence of people.
The paper considers the issues of ensuring the integrity of the flow of information messages between remote objects and identification of the data transmission channel, interrupted randomly by ...fragmentation-defragmentation processes of this flow as a result of the stochastic appearance and disappearance of traces from meteors burning in the ionosphere, which are used as passive repeaters of VHF radio signals that carry out energy contact between correspondents of a computer network. The problem is posed to implement an algorithm for discontinuous transmission of a continuous data stream over a meteor communication network without distortion and loss of transmitted messages without the inclusion of redundant signs, which contributes to a more rational use of the limited telecommunication resource of the meteor communication network. It is shown that to ensure a reliable exchange of information data between remote infrastructure facilities of the Northern Sea Route, a meteor trail can be used, which will provide a statistically stable connection with the fulfilment of the requirements for the probability of receiving false signs while maintaining the integrity of messages, provided that this type of communication between correspondents is discontinuous.
Background.
Improving organizational technologies for early detection of cancer using targeted programs for large-scale cancer screening is a priority task of primary health care.
The aim:
to assess ...the potential of lean technologies to optimize cancer screening during periodic health examination of the adult population.
Materials and methods.
To develop an optimal organizational and functional model of cancer screening, a working group was created; information about the current state of the process was collected.
Results.
A comprehensive analysis of the state of the process revealed the following problems: violation of the algorithms of oncological screening at stage 1 of periodic health examination (13.8 %); cases of non-completion of stage 2 of periodic health examination by patients with suspected colon cancer (20.4 %); queues for endoscopic examinations (14 days) and, as a consequence, not a quick visit to the oncologist of the primary oncology department (17–18 days). After optimization of the periodic health examination: there is no queue for endoscopy for patients with suspected oncopathology; accelerated access of patients with suspected oncopathology to the oncologist of the primary oncology department (from 17–18 to 5 days; p < 0.01). Increased awareness of patients about the rules for preparing for endoscopic examination and a reminder of the date and time of the upcoming endoscopy, there was an increase in the number of patients who completed stage 2 of health examination to exclude/confirm oncopathology (from 79.6 to 90 %; p < 0.05). The frequency of violations by doctors of the oncological screening algorithm decreased from 13.8 to 2.3 % (p < 0.01).
Conclusion.
The use of lean manufacturing marketing strategies in primary health care has helped to identify, eliminate and control the causes of problems during the first and second stages of clinical examination of patients with suspected oncopathology.
A procedure is developed for the rapid screening and sensitive determination of penicillins G and V in vegetables and fruits using ultra-high-performance liquid chromatography‒quadrupole ...time-of-flight high resolution mass spectrometry for exact masses of ions of protonated penicillin adducts with methanol. A simple and quick method of sample preparation (simplified QuEChERS method) is proposed for the analysis of fruits and vegetables (oranges, lemons, plums, pears, peaches, cabbage, potatoes, onions, carrots, beets, avocados, cucumbers, tomatoes, eggplants). Identification is carried out by the exact ion masses of analytes, retention time, and the pattern of the isotope distribution of ions (mSigma). Because of the significant matrix effect, analysis should be performed by the method of standard additions, by internal standard method (oxacillin), or using matrix grading. The limits of detection were 0.05‒0.3 ng/g, the analytical ranges were 0.2 (0.9)‒10 ng/g (

Aim To analyze frequency and profile of the lipid-lowering therapy (LLT) in patients with dyslipidemia (DLP) and cardiometabolic diseases (CMD) in a population sample aged 55-84 years at the ...current time (2015-2017).Material and methods Despite guidelines on DLP treatment and the availability of effective and safe lipid-lowering drugs, control of DPL in primary and secondary prevention of cardiovascular diseases (CVD) is insufficient. Knowledge of the level of pharmaceutical correction of DLP in the Russian population is limited; it requires an LLT assessment in various regions and in a wide age range, and a regular monitoring taking into account changing approaches to the correction of DLP. A random population of men and women aged 55-84 years (n=3 896) was evaluated in Novosibirsk in 2015-2017 (project HAPIEE). A joint DLP category was established as low-density lipoprotein cholesterol (LDL-C) ≥3.0 mmol/l, or total cholesterol (TC) ≥5.0 mmol/l, or triglycerides (TG) ≥1.7 mmol/l, or LLT. The combined group of DLP and CMD included ischemic heart disease (IHD), type 2 diabetes mellitus (DM2), and DLP. Regular LLD treatment for the recent 12 months, excluding the dosage of medicines, was assessed using the Anatomic Therapeutic Chemical (ATC) classification. The conditional control of serum lipids was taken as the achievement of LDL-C <3.0 mmol/l, TC <5.0 mmol/l, and TG <1.7 mmol/l.Results In the study sample, the total prevalence of DLP and CMD was 88 % (82.8 % for men and 91.3 % for women, p<0.001). 48.3% of patients in the IHD group, 35.0% in the DM2 group, 29.4% in the DLP group, and 32.8% in the CMD group took LLT. Control of serum lipids was achieved in 18.3% (37.9 % of patients on LLT) of patients with IHD; 9 % (25.6 % of patients on LLT) of patients with DM2; 7.3 % (24.8 % of patients on LLT) of patients with DLP; and 9.0 % (27.6 % of patients on LLTсреди) in the DLP and CMD group. Women with DM2 and DLP more frequently achieved lipid control than men (p<0.001). 98.7 % of study participants took statins as LLT.Conclusion In the sample of urban population aged 55-84 years in 2015-2017, 90 % of patients had DLP or CMD, and at least ¾ of them required blood lipid control. The lipid control was achieved in every fifth IHD patient and in approximately 40% of those who took LLT. For DM2 or DLP patients, the lipid control was achieved in every tenth patient and in approximately 25% of those receiving LLT. Frequency of lipid control in IHD patients was comparable for men and women; in DM2 and DLP, men less frequently achieved the lipid control than women. About 70% of patients in the combined DLP and CMD group and more than 50% of IHD patients did not take LLT, which considerably contributed to the insufficient lipid control in primary and secondary prevention of atherosclerotic CVDs in this population.
