Objective: The aim: The study of cytomorphological and cytogenetic features of the buccal epithelium of residents of apartments who complained of unpleasant odors in their homes., Patients and Methods: Materials and methods: The state of buccal epithelium in residents of multi-story buildings was studied. A total of 237 individuals were examined, 117 males and 120 females, aged from 6 to 81 years. Buccal cells were collected using a sterile spatula and stained with a 2.5% solutionofaceto-orcein and 1% light green. The preparations were examined using a light microscope OPTON Axioskop (Germany) with oil immersion at a magnification of x1000. Statistical processing of the data was performed using IBMSPSS Statistics 29.0.0.0 (t-Student criterion; Mann-Whitney; ANOVA: Tukey; T3-Dunnett), with p≤0.05., Results: Results: Cytomorphological and cytogenetic abnormalities, compared to physiological limits, were mainly manifested as karyorrhexis, nuclear doubling, the appearance of epitheliocytes with perinuclear vacuoles, or nuclear vacuolization. The frequency of micronuclei was observed in the range of (0.3-2.8 ‰). The highest micronucleus index (per 1000 cells, ‰) was observed among males aged 15-39 years and females over 65 years old. In both sexes, the lowest micronucleus indices were found in the age group of 6-14 years., Conclusion: Conclusions: in the «sick building» an increase in the frequency of micronucleus occurrence among males and females was observed simultaneously with increasing age.

Objective: The aim: Scientific justification of the public health management methods and instruments for improvement of its effectiveness., Patients and Methods: Materials and methods: The authors conducted a complex research of the public health of Ukraine personnel resources development during the system establishment and building., Conclusion: Conclusions: The paper justifies the competence-based model of a specialist (the postgraduate educational level) as well as the university educational standards of the first (bachelor) and second (master) levels of specialty 229 "Public health", knowledge branch 22 "Healthcare". The authors have established insufficient level of the youth motivation for obtaining the specialty certification and described disadvantages of both advocacy program within the public health system and its leadership within the preventive system component. The authors emphasize the necessity of an integrated preventive program maintaining and strengthening the population health, using the advocacy component and available information resources of the public health.

Objective: The aim: To determine learners' (doctors) needs and draw up proposals for upgrading educational communication processes in the "provider-consumer" system of educational services., Patients and Methods: Materials and methods: The biblio-semantic, biostatistic and sociological methods were used. 754 author questionnaires were processed., Results: Results: The socio-professional characteristics of learning service consumers at Shupyk National Medical Academy of Postgraduate Education were analyzed as well as studied their proposals. Evaluating communication interactions in the "provider-consumer" system of educational services concerned determining the most comfortable organizational modes of education for a consumer, making a careful analysis of the learning service characteristics by "accessibility" and "effectiveness" criteria. The determination methodology and research results can be used by universities and colleges regardless of the educational program specialization., Conclusion: Conclusions: Ensuring the educational communication processes effectiveness in the "provider-consumer" system of educational services is achieved by studying learners' adaptation according to such principal criteria as organizational modes of education, the learning service accessibility and effectiveness. The learning service providers adjust customer requirements to the capabilities of a particular educational institution (personnel availability, facilities and resources etc.) and so that they ensure competitiveness.

Objective: Introduction: Training programs for workforce in health area considered as a topical issue and regulates by numerous international and national standards and guidance. In public health system development circumstances the issue of enhance competences for doctors becomes particularly important. Modern achievements of andragogy, sociology and psychology can greatly improve the educational processes in training personnel for public health needs. The aim: to rationalize methodological approaches for efficiency improvement of the competency model for training public health experts in a reforming environment of the healthcare service in Ukraine., Patients and Methods: Materials and methods: semantic, systemic and biostatistical analyses, modelling peer review., Results: Results: improvement in medical competency becomes increasingly relevant under the developing public health sector. The postgraduate training model is reviewed for improvement in its efficiency. Driving forces, analyzed and identified for the model establishment, are educational process regulation, logistics and staffing development status, opportunity to consider needs of educational service consumers. Possibilities of improving the postgraduate educational process are rationalized by the survey among physicians and heads of preventive medicine as an example, principal organizational forms and methods are defined as well., Conclusion: Conclusions: The provision of education demands further improvement and development in a reforming and more competitive environment. Curriculums, programmes and their organizational forms planning, use of a variety of pedagogical tools are unachievable without considering attitudes of educational service consumers ( by peer review), that provides higher efficiency and quality of educational activities aiming for improvement in competency of public health experts. Improving the regulation, professionalization of scholars, by means of present-day advances in information technology, turn crucial elements of the competency model of postgraduate education.

Objective: To evaluate the health status of adult population living in the Ukrainian nuclear power industry obser vation zone on the example of Zaporizhzhia Nuclear Power Plant., Materials and Methods: System review, analytic, sociological survey and statistical methods., Results: There was established an increase in the incidence of digestive diseases among adult population in Nikopol of Dnipropetrovsk region, which is included in the Zaporizhzhia NPP observation zone. The highest increase was observed in the incidence of peptic ulcer, gastritis and duodenitis, cholecystitis and cholangitis by 340 %, 305 % and 83 %, respectively., Conclusions: In connection with the residence in industrially developed region and NPP life extension in Ukraine, the possible influence of harmful factors on health status of the population of observation zones, an increase in the incidence of digestive diseases among adult population, there is required continuous monitoring and detailed study of public health., (I.

Within all these years after the Chernobyl disaster the population of contaminated areas of the Rivne region was shown to consume radioactive contaminated foodstuffs. The main components of the formation of the internal irradiation of the population in them were and remain locally sourced milk and meat, forest mushrooms and berries. After 1991, the largest annual internal doses in persons observed in 1997 varied from 2,2 to 1,45 mSv/year and in 2011--in the inhabitants of the village of El'no they were yet reaching 1.43 mSv/year. After 2003, exposure levels in most inhabitatants of affected areas exceeded the criterion specified by national legislation for residents of the tightened radioecological control zone (0,5 mSv/year). The long-term residence in the contaminated area, elevated levels of chronic internal exposure, lack of radioactively sound foodstuffs and involuntary consumption in 1987-2011 radioactively contaminated food of local production were noted to led to an increase in general morbidity, and incidence of endocrine diseases rate and their separate nosological forms.

Influence of electrolysis gaseous oxygen (EGO) mixed with nitrogen (1:4) on the living organism was studied in a 30-day 24-hour experiment on guinea pigs. A preliminary conclusion states, that EGO, obtained in the system with a solid polymeric electrolyte out of moist materials of different chemical composition, can be recommended for the formation of artificial gas atmosphere in hermetic objects in the mixture with gaseous nitrogen in the ratio 1:4.

The National Commission on Radiation Defense (NCRD) of the USSR Health Ministry proposed standard values--maximum limit of life dose for the population equalling 35 ber per 70 years. Despite the seeming accordance of this value to NCRD recommendations according to which the equivalent dose of irradiation of a limited part of the population should not exceed 0.5 ber yearly, the NCRD does not take into consideration the irregular character of radiation. Numerous data from the literature are presented on the presence of some nonstochastic and stochastic effects even in such comparatively low doses showing the impossibility of acceptance of such standard values.
