Statistical coding of natural closed contours

Many authors point to the low incidence of occupational diseases in our country. The reasons are poor-quality preventive examinations, the lack of interest of employers in identifying these diseases, and others. However, there are no works in the literature devoted to errors in the statistical coding of diagnoses of occupational pathology and their accounting. The study aims to improve the accounting of occupational diseases in Russia. We conducted the study using the information base of the Industry Register of Persons with Occupational Diseases, developed by Burnazyan State Medical Center of the FMBA, Russia, which operating in the industry since 2011. As of 31.12.2020, the register contains information on 2,056 patients with occupational diseases, from among the employees of enterprises and organizations served by healthcare institutions of the FMBA, Russia. Errors of incorrect coding of diagnoses for occupational diseases with violation of the classification principles in the used directive materials played a negative role. The development of plans for medical and social rehabilitation measures to reduce the incidence of occupational diseases among the people working in harmful conditions. It requires correct knowledge of morbidity indicators of this nosology. In order to improve the accounting of occupational diseases in Russia, it is necessary to switch to the system of coding diagnoses of this nosology, adopted in medical statistics, and make appropriate changes to the directive documents.

Statistical Coding

This paper proposes a statistical coding methodology using covert side channel information to solve timing packet security issue, the main purpose here is to enhance the security of the timing protocol with backward compatible capability. In wireless communications, either ad-hoc military/ industrial network, or LTE/ LTE-A networks, GPS is used to provide time and location; however, the hackers often trying to spoof the signal. The alternative way of providing such signal is using protocols like IEEE1588 Precision Time Protocol (PTP); unfortunately, current timing packet is not encrypted, it can be altered by the hackers. To maintain the simplicity of such protocols, most vendors are reluctant to add encryption on top of it; nevertheless, the end customer wishes to see it. To solve this dilemma, we propose a backward compatible solution here. The basic idea is demonstrated using Matlab FFT calculation tool. The future extension using Fractional FFT is also suggested at.
