Subject. digital technologies used by the service of examination of temporary disability associated with a dental disease and their adoption in dental medical organizations of the Republic of Tatarstan. The aim — to develop a computer simulation program for predicting the duration of temporary disability associated with a dental disease. Results. Odontogenic inflammatory processes, which were identified in 66.1% of the cases, represented the largest proportion of causes of temporary disability in patients of dental medical organizations. Maxillofacial traumas took the second place with a proportion of 13.9% of all the causes. Diseases related to loss of teeth due to extraction were identified in 384 patients, or in 7.4% of cases, and took the third place. The authors of the study determined the duration of temporary disability for each category of dental disease in the Republic of Tatarstan, the average duration of which was 8.48 ± 0.04 days. Based on clinical statistical analysis, a matrix was created for predicting the duration of dental diseases leading to temporary disability represented by a computer software for dental medical organizations. Conclusions. Dental diseases in patients are related to the cases where treatment and rehabilitation are provided by several medical organizations; the authors created software for dentists, which predicts the duration of cases, their statistical analysis, eliminates errors in the issue of sick leave certificates, draws standard reporting statistical documents in order to provide reliable information on the state of the economically active population, to plan preventive activities, appropriate comprehensive treatment and rehabilitation of patients.

Aim. To study the seasonality of diseases of the maxillofacial region as a factor affecting the duration of temporary disability in the Republic of Tatarstan. Methods. The sources of information were the cases of temporary disability established by dental medical organizations of the Republic of Tatarstan (analysis of accounting and reporting forms 16-VN, 036/u, 035/u, 043/u for the period 20072016). Results. The number of visits to dental medical organizations of the patients with diseases of the maxillofacial region leading to disability of the patient was different depending on the season. It was found that the differences in the structure of temporary disability due to diseases depending on the season for different years of the study period were statistically significant (p 0.001) in all groups except non-odontogenic inflammatory diseases. We have established two periods with an increased number of cases from March to April and from October to December. In these months, cases of temporary disability in the general structure accounted for 8.9% and more. Conclusion. Analysis of morbidity and factors leading to the occurrence of cases of temporary disability allows obtaining reliable information about the health of the economically active population of the Republic of Tatarstan, which will be the basis for planning preventive measures, appropriate comprehensive treatment and rehabilitation of patients.

Abstract The authors have been developed a computer simulation program of gear shaving. In the present paper, a new cutting model of shaving process is proposed so as to incorporate an effect of a cutting performance of shaving cutter into the simulation program. In this cutting model, it is assumed that a tooth flank material of work gear can be removed only when a depth of cut of a cutting edge exceeds a certain criterion. It is also assumed that the criterion have no definite value but has the nominal distribution over the tooth surface. The mean value of the distribution can define a characteristic of cutting performance of shaving cutter. The small mean value means that even small depth of cut can cause a stock removal; i.e. a good cutter performance. The computer simulations on gear shaving are performed to reveal the effect of the cutter performance on shaved tooth form. Under the conditions used in these simulations, the pressure angle error on the shaved tooth profile becomes remarkable as the cutter performance becomes worse. Thus, the developed computer simulation program of gear shaving has a reliability on the prediction of shaved tooth form. It will be useful for design of shaving cutter, judgement of tool life, and so on.

In this paper we investigate the performance of an integrated solar photovoltaic and thermal (PV/T) liquid (water) collector using a computational simulation program. A detailed time-dependent thermal model was formulated to calculate and correlate the thermal parameters in a standard PV/T collector, including solar cell temperature, back surface temperature, and outlet water temperature. Based on the energy balance of each component of the system, an analytical expression for the temperature of the PV module and the water was derived. In addition, an analytical expression for the instantaneous energy efficiency of the PV/T collector was also derived in terms of thermal, design and climatic parameters. Built on previously published model, a new computer simulation program was developed and validated. The thermal simulation results obtained are more precise than those previously reported in the literature.

This paper presents the part of results obtained by a comprehensive statistical analysis of public opinion in the issue of work-free Sunday, based on a survey undertaken in the Republic of Croatia in October 2017. The research has been made aiming at providing the answer to the crucial question of whether free Sunday can be considered only as of the economic issue or concerns deeply almost all the spheres of life in general. Moreover, the authors want to show and promote free Sunday as socio-economic phenomena which become a political and ideological issue as a fundamental human right and true notion of human freedom and welfare. Besides, as a member of the European Sunday Alliance, Croatia is the first EU member state which promotes free Sunday as one of the measures of active demographic policy. Along with the results of classical statistical processing of public opinion research, the methodology of this research has also involved the hypothesis testing about differences in the proportions as well as post-stratification of the two-step stratified random sample based on gender, age, size of residence, regions and education level. Even more, than two-thirds of respondents consider important or exceptionally important not-working on Sundays and support the maximum limit of that work.

In the modular construction of ships, significant productivity losses can occur during the erection stage, when the modules, or hull blocks, are joined together. Frequently, adjacent blocks do not fit together properly, and rework of one or both of the mating block interfaces is necessary to correct the problem. The specific cause of rework is the variation of plate edges at the block interface, which is itself a cumulative product of numerous manufacturing variations inherent in hull block construction. Variation in manufacturing is unavoidable, but not uncontrollable. The application of accuracy control techniques in shipbuilding has proven that a statistical analysis of variation makes possible an accurate prediction of its effects. This paper presents an examination of block interface variation, and the subsequent development of a computer simulation method of predicting rework levels on those blocks. The complex interaction of all the edges' random variations at the block interface gives rise to a unique rework probability distribution. This probability distribution is evaluated by means of the computer simulation program, which provides estimates of the average rework anticipated, the shape of the probability curve, and other parameters. Similar predictions are also available for cost and labor of required rework. In addition to predicting rework levels, the simulation program can be a useful tool for reducing those levels.
