Lecture Course “Modern Physics”

In the paper, the structure of the lecture course “Modern Physics” is described in detail. The course is based on a logical presentation of modern ideas about quantum-, atomic-, nuclear-, and molecular physics as well as astrophysics. A special attention is paid to a relatively new interdisciplinary research field, namely the physics of open systems, and to the study of clusters as one of the most promising scientific areas. Separate chapters of the textbook are devoted to nonlinear optics, quantum information, structure and dynamics of molecules. The fundamental laws and concepts of modern physics, their relationship and origin are comprehensively discussed. It is underlined that this lecture course is intended, first of all, for students of technical universities, postgraduate students of relevant specialties, as well as professors of vocation-related subjects. The inclusion of new sections of physics in the curricula of universities is rationalized, in particular, by the fact that physics is closely related to engineering. Due to this fact, the important role that physics plays in society becomes especially evident. The paper may also be of interest to those who are fond of physics and its state-of-the art

Different healthy habits between northern and southern Spanish school children

Aim: Healthy habits are influenced by several factors such as, geographical location. The aims of this study were to describe and compare healthy habits within two populations of sixth-grade primary school children (aged 11-12 years) from Northern and Southern Spain. Subject and Methods: A cross-sectional study using two representative samples of school children was conducted. Participants came from Logroño (n=329), in the North and Granada (n=284), in the South of Spain. Socio-demographic and anthropometric variables, adherence to the Mediterranean diet, aerobic fitness, and healthy lifestyles were recorded. Results: Boys reported higher level of physical activity and aerobic fitness than girls (p=0.000). Southern school children reported significantly higher adherence to the Mediterranean diet (♀: p=0.041; ♂: p=0.008), and lower aerobic fitness (♀: p=0.000; ♂: p=0.042) and hours of nightly sleep (♀: p=0.008, ♂: p=0.007) than Northern school children. Southern boys also reported lower levels of physical activity (p=0.013). There were slight or moderate correlations among all habits measured (physical activity, diet, screen and sleep time). Additionally, physical activity level was inversely related to body mass index in Northern boys (p=0.020) and Southern girls (p=0.024). Conclusions: Results showed differences in physical activity, eating and sleep habits, and aerobic fitness, according to geographical location. The relationships found among lifestyle habits indicate the need of health promotion interventions nationally and considering the differences discussed here

High-Intensity Interval Training Interventions in Children and Adolescents: A Systematic Review

BackgroundWhilst there is increasing interest in the efficacy of high-intensity interval training in children and adolescents as a time-effective method of eliciting health benefits, there remains little consensus within the literature regarding the most effective means for delivering a high-intensity interval training intervention. Given the global health issues surrounding childhood obesity and associated health implications, the identification of effective intervention strategies is imperative.ObjectivesThe aim of this review was to examine high-intensity interval training as a means of influencing key health parameters and to elucidate the most effective high-intensity interval training protocol.MethodsStudies were included if they: (1) studied healthy children and/or adolescents (aged 5–18 years); (2) prescribed an intervention that was deemed high intensity; and (3) reported health-related outcome measures.ResultsA total of 2092 studies were initially retrieved from four databases. Studies that were deemed to meet the criteria were downloaded in their entirety and independently assessed for relevance by two authors using the pre-determined criteria. From this, 13 studies were deemed suitable. This review found that high-intensity interval training in children and adolescents is a time-effective method of improving cardiovascular disease biomarkers, but evidence regarding other health-related measures is more equivocal. Running-based sessions, at an intensity of >90% heart rate maximum/100–130% maximal aerobic velocity, two to three times a week and with a minimum intervention duration of 7 weeks, elicit the greatest improvements in participant health.ConclusionWhile high-intensity interval training improves cardiovascular disease biomarkers, and the evidence supports the effectiveness of running-based sessions, as outlined above, further recommendations as to optimal exercise duration and rest intervals remain ambiguous owing to the paucity of literature and the methodological limitations of studies presently available

The quality of early breast cancer diagnosis in urban women by doctors of adult polyclinics

In oncology, one of the leading places belongs to breast cancer. This problem is particularly significant in the current situation, when the issue of reproductive health of the female population is acute lyuped in connection with the unfavourable demographic trends in our country. Early diagnosis of precancerous diseases and initial stages of cancer is possible only with active search of patients among practically healthy people. However, despite the availability of breast for examination in adult clinics, malignant tumors of these locations are often found with considerable delay. The most important factor in the success of early diagnosis of oncopathology is the work of primary health care physicians. However, there have been no studies on the quality of early diagnosis of breast cancer in urban women in modern seffings. Purpose of the study. to study the quality of early diagnosis of breast cancer in urban women by doctors of adult polyclinics. Materials and methods. Adult clinics №.1, 2, 3, 4, 5, 6, 7, 8, 11, 12 of Ivanovo have been identified as the basis of the study. The study was conducted in 2018. The program of the study included the use of methods: expert, sociological, mathematical and statistical. Surveillance units: a woman with a malignant breast formation living in the city; case of detected and confirmed malignant breast formation. A retrospective analysis of 600 expert opinions was carried out, the survey method on the questionnaire studied women's satisfaction with premorbid prevention in the adult clinic and the availability of early diagnosis of breast cancer (100 patients). The data were processed using applied computer programs. Results. It has been established that the main causes of late diagnosis of breast cancer in urban women are: untimely treatment of the patient in a medical and preventive institution, deviations from the standard of examination of women for oncopathology, errors in diagnosis, features of the course of the disease (lightning or latent form), non-compliance with continuity in the management of the patient.Conclusion. Analysis of expert opinions on advanced cases of breast cancer showed that the bulk of the defects detected are preventable and are associated with low cancer of doctors and failure to fully and properly perform the standard of examination oncopathology

FEATURES OF THE TECHNOLOGICAL COMPONENT OF THE IVANOVO REGION HEALTH SYSTEM POLICY IN MALIGNANT TUMORS EARLY DIAGNOSIS

Purpose of the stydy. To study the Features of the technological component of the Ivanovo region health system policy in malignant tumors early diagnosisMaterials and methods. The base of the research is the Ivanovo Regional Oncology Dispensery, Department of Health of the Ivanovo Region. Methods: sociological, expert assessment, analytical, documentary. The assessment of the technological component of oncological service policy was carried out in the three areas: a) an assessment of the quality of oncological assistance using the method of correspondence examination of completed cases of assistance with filling out expert assessment cards (600 cases of assistance); b) an assessment of patients' satisfaction with the help provided by the method of a sociological questionnaire survey (600 patients); c) an assessment of the apparent patients' dissatisfaction with the help provided based on the analysis of justified complaints (30 people).Results. The expertize of oncological medical services provided showed that there is a decrease in a number of its properties in modern conditions. The first ranking places in terms of the frequency of violations belong to the following properties of medical services quality: timeliness; adequacy; continuity; performance, availability. In the structure of medical and organizational defects in the quality of care, according to the results of expert evaluation, the leading part of them- 70.5% — is occupied by diagnostic defects (non-compliance by the medical personnel with the oncological screening standard, non-use of instrumental and laboratory research methods).Conclusion. The policy of oncological care quality has signs of decrease (the number of diagnostic and medical-organi­zational defects averages 1.7 for each case of diagnosed cancer), which leads to advanced cases of oncopathology. The results of the study showed that the current system of oncological care in modern conditions is not sufficiently effective and requires improvement, including by increasing the doctors' level of cancer alertness, increasing the efficiency of the regional cancer pathology commissions
