    Abstract Background and aims: On March 16, 2020, the state of emergency was established with drastic measures of isolation and quarantine. Among the measures taken in the context of the state of emergency was the closure of dental offices throughout the country. The aim of our questionnaire-based cross-sectional study was to identify the psycho-affective implications of the Romanian citizens induced by the COVID-19 pandemic period as well as their opinion related to the self-perceived oral health status during this period.
    Methods: An original questionnaire was designed consisting of 41 questions, which were distributed to the general population via the Internet. The first part of the questionnaire investigated the respondents' opinion regarding the impact of this COVID-19 pandemic period of isolation on their oral health and the attention paid by the subjects to oral hygiene during restrictions. The second part refers to their addressability to the dental services during this pandemic and the third part interrogates different characteristics, namely the presence of comorbidities, possible anxiety, and stress.
    Results: A total of 769 participants answered the questionnaire online.
    Conclusion: According to their responses most of the respondents were not afraid of the possibility of contracting Sars-Cov-2 during dental treatments, but were in certain periods deprived of accessing dental services due to lockdown restrictions. They are aware of their oral health problems and pay more attention to oral hygiene so that they do not get worse during restrictions.

    Abstract Light emitting diodes (LED) are becoming the dominant lighting elements due to their efficiency. Optical camera communications (OCC), the branch of visible light communications (VLC) that uses video cameras as receivers, is a suitable candidate in facilitating the development of new communication solutions for the broader public because video cameras are available on almost any smartphone nowadays. Unfortunately, most OCC systems that have been proposed until now require either expensive and specialized high-frame-rate cameras as receivers, which are unavailable on smartphones, or they rely on the rolling shutter effect, being sensitive to camera movement and pointing direction, they produce light flicker when low-frame-rate cameras are used, or they must discern between more than two light intensity values, affecting the robustness of the decoding process. This paper presents in detail the design of an OCC system that overcomes these limitations, being designed for receivers capturing 120 frames per second and being easily adaptable for any other frame rate. The system does not rely on the rolling shutter effect, thus making it insensitive to camera movement during frame acquisition and less demanding about camera resolution. It can work with reflected light, requiring neither a direct line of sight to the light source nor high resolution image sensors. The proposed communication is invariant to the moment when the transmitter and the receiver are started as the communication is self-synchronized, without any other exchange of information between the transmitter and the receiver, without producing light flicker, and requires only two levels of brightness to be detected (light on and light off). The proposed system overcomes the challenge of not producing light flicker even when it is adapted to work with very low-frame-rate receivers. This paper presents the statistical analysis of the communication performance and discusses its implementation in an indoor localization system.
