RESUMO
The population awareness about merits of mandatory medical insurance (MMI) continues to be inadequate. The study purpose was to investigate opinion of Moscow Oblast residents about MMI system. The sociological survey was carried out according standard technique using specially developed genuine questionnaire. The public opinion was studied in 2013 (584 respondents) and 2017 (709 respondents) on the basis of sampling of visitors of medical organizations. The survey established that percentage of positive responses of respondents concerning their awareness about which medical insurance company they belong slightly increased in 2017. However, every thirteenth still was unaware of it. Only every sixth respondent addresses to insurance company when occur problems related to medical care support. The right to choose insurance company, medical organization and physician was used by 17-22% of respondents in both surveys. In 2013 20% of respondents addressed nowhere due to absence of problems with health services support. In 2017, number of addresses to administrations of medical institutions increased up to 35%. The number of addresses to insurance companies and MMI foundations increased up to 13% and 27% correspondingly. The percentage of respondents with positive answers about being constrained to pay for medical services unofficially decreased up to 18% in 4 years and reached 12,6% in all sampling. Thus, activities concerning population information about changes occurring in health care system, including development of citizen rights is inadequate still. The citizens in number of cases are not interested to obtain necessary information and ignore it down to name of insurance company mentioned on their insurance policy.

Three experiments are reviewed, performed (in 2014-2016) at ID18 of ESRF to measure the influence of acceleration on time dilation by measuring the relative shift between the absorption lines of two states of the same rotating absorber with accelerations anti-parallel and parallel to the incident beam. Statistically significant data for rotation frequencies up to 510â Hz in both directions of rotation were collected. For each run with high rotation, a stable statistically significant `vibration-free' relative shift between the absorption lines of the two states was measured. This may indicate the influence of acceleration on time dilation. However, the measured relative shift was also affected by the use of a slit necessary to focus the beam to the axis of rotation to a focal spot of sub-micrometre size. The introduction of the slit broke the symmetry in the absorption lines due to the nuclear lighthouse effect and affected the measured relative shift, preventing to claim conclusively the influence of acceleration on time dilation. Assuming that this loss of symmetry is of first order, the zero value of the relative shift, corrected for this loss, falls always within the experimental error limits, as predicted by Einstein's clock hypothesis. The requirements and an indispensable plan for a conclusive experiment, once the improved technology becomes available, is presented. This will be useful to future experimentalists wishing to pursue this experiment or a related rotor experiment involving a Mössbauer absorber and a synchrotron Mössbauer source.
RESUMO
New results, additional techniques and know-how acquired, developed and employed in a recent HC-1898 experiment at the Nuclear Resonance Beamline ID18 of ESRF are presented, in the quest to explore the acceleration effect on time dilation. Using the specially modified Synchrotron Mössbauer Source and KB-optics together with a rotating single-line semicircular Mössbauer absorber on the rim of a specially designed rotating disk, the aim was to measure the relative spectral shift between the spectra of two states when the acceleration of the absorber is anti-parallel and parallel to the source. A control system was used for the first time and a method to quantify the effects of non-random vibrations on the spectral shift was developed. For several runs where the effect of these vibrations was negligible, a stable statistically significant non-zero relative shift was observed. This suggests the influence of acceleration on time.
