We derived three samples from the collected data on the DMFT index – small (n = 50), medium-sized (n = 100), and the entire sample (n = 200). Afterwards, we ran Monte Carlo simulations (MCS) to derive DMFT index data for three student populations of 20 000 individuals each from those samples. The probabilities of individual outcomes for the DMFT index and its components, as well as their correla-tions, were entered as assumptions for the MCS.Results: The estimated mean DMFT index of the student population was 8.96 (standard deviation (SD) = 0.69, 99% CI = 8.91–9.00) for MCS 50, 9.12 (SD = 0.47, 99% CI = 9.08–9.21) for MCS 100, and 8.82 (SD = 0.36, 99% CI = 8.77–8.87) for MCS 200. Regarding the components of the DMFT index, the number of repaired teeth in MCS 50, MCS 100, and MCS 200 was most strongly correlated with the DMFT index, with R values of 0.84, 0.82, and 0.77, respectively. The estimated mean DMFT indices by MCS differed from the mean DMFT indices of the corresponding samples and each other by less than 1 point.Conclusions: The Monte Carlo method may be useful in es-timating the population means of clinical indices in dental medicine, including the DMFT index. According to the as-sumptions made for MCS in this study, the size of the origi-nal samples did not significantly affect the estimates of the parameters of the DMFT index.","PeriodicalId":422483,"journal":{"name":"St open","volume":"114 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140669401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is expected that the ongoing Russian aggression will augment this problem. The study aimed to analyze the trends of work disability due to CVDs in newly-diagnosed patients between 2013 and 2022. Methods: This retrospective study included data obtained from the official document “Report on the Causes of Disability and Indications for Medical, Professional, and Social Rehabilitation” commissioned by the Ministry of Health of Ukraine. The data on disability due to CVD were obtained from 24 regions and the city of Kyiv for 2013-2022. Results: Between 2013 and 2022, the average incidence of work disability due to CVD per 10000 working-age individuals was 9.86. Among these disabilities, cerebrovascular diseases accounted for the highest proportion, followed by ischemic heart disease (IHD). The incidence of CVD-related primary disabilities displayed a variable upward trend over the observed period, with cerebrovascular diseases and hypertensive diseases showing clear upward trends. Compared to 2021, in the year 2022 (corresponding to the beginning of the Russian aggression) an 20% increase has been observed for CVDs, while for cerebrovascular diseases, IHD, hypertensive disease, acute rheumatic fever, and chronic rheumatic heart disease the increase was 20%, 18%, 22%, and 14%, respectively. The CVD-related work disability varied substantially in different regions of Ukraine. Conclusions: During the first year of the war in Ukraine (the year 2022) there was an increase in primary disability due to CVD compared to the period between 2013 and 2021. This may be associated with war-related psychosocial factors and global impact on CVD. The regions in southwestern parts of Ukraine proved to be especially prone to this increase requiring special attention.","PeriodicalId":422483,"journal":{"name":"St open","volume":"2006 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135635788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The crime of perjury in the legislation of the Republic of Croatia","authors":"Damir Juras","doi":"10.48188/so.4.14","DOIUrl":"https://doi.org/10.48188/so.4.14","url":null,"abstract":"Objective: The paper aims to provide a description and analysis of perjury in the legislation of the Republic of Croatia, the standpoints of legal theory, and perjury charges and prosecution in practice. Methods: This paper presents an analysis of legal provisions concerning the crime of perjury in Croatia, statistical data on perjury charges and conviction rates, perspectives of other authors, and relevant judicial practice. Results: The legislator has established criminal liability for perjury on the part of any witness, expert, translator, or interpreter who provides false testimony in a procedure. On the other hand, parties other than the defendant are liable for perjury if the final decision in the procedure was based on their false testimony. Legal theory and judicial practice agree that the crime is committed as soon as the person has finished testifying, that a prescribed format should be observed when testifying, that perjury may also be committed by withholding a decisive fact, as well as that in general, a retrial of a proceeding in which the perjury allegedly occurred is permissible only if based on a final judgment against the perjurer. An exceedingly large percentage of suspended sentences may fail to advance either general or specific deterrence. Regarding the contentious issue of necessary conditions for initiating perjury proceedings, the author argues that the conditions are met immediately upon providing false testimony. Conclusion: The legislator has criminalized perjury because providing false testimony constitutes a willful and intentional obstruction of the process of proving facts in issue in proceedings before competent authorities. The judicial sentencing policy is not consistent regarding the application of prescribed punishment. By stipulating criminal liability of a party only if their testimony was instrumental for the judgment, the party unjustifiably enjoys a more favorable position in relation to witnesses, experts, interpreters, and translators.","PeriodicalId":422483,"journal":{"name":"St open","volume":"15 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135634151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Šćulac","doi":"10.48188/so.4.13","DOIUrl":"https://doi.org/10.48188/so.4.13","url":null,"abstract":"Aim: To develop a simple algorithm that accurately constructs and simulates an Alvarez-type linear accelerator given the initial conditions and number of accelerator parts.Methods: We wrote the algorithm in Python, a programming language with numerous useful math and science libraries, and the ability to use classes and objects. The particles were accelerated in electric fields (which we assumed to be constant within each cavity at any given moment) to allow for a comparison of numerical results with an analytic expression. No magnetic fields were present in the simulations used in this article, and the particle beams were instead focused by using collimators. The algorithm first constructed the accelerator by guessing the appropriate length of each segment until it found optimal lengths for accelerating most particles in the beam. Once constructed, the accelerator could accelerate beams of particles and the results could be analyzed.Results: The algorithm successfully constructed multiple different accelerators from the initially given conditions. The first two simulations had arbitrary accelerators in which hydrogen and lead ions were accelerated, and the results were in line with expectations from the analytic solution. The largest simulation was that of CERN’s Linac4 accelerator, which produced results similar to those found in the real world.Conclusion: Significant results could be obtained even with an algorithm as simple as the one described here. The algorithm could be further improved by using a more realistic potential inside the accelerator cavities, and more particles could pass through if magnetic fields which focus the beam were turned on","PeriodicalId":422483,"journal":{"name":"St open","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127173389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Periodontal indices included plaque index (PI), bleeding on probing (BoP), pocket probing depth (PPD), and clinical attachment level (CAL). We estimated hard tooth tissues using the decayed, missing, filled permanent teeth (DMFT) index. We also collected basic medical history data and oral hygiene habits, as well as oral health-related quality of life data through the Oral Health Impact Profile (OHIP-14) questionnaire.Results: Fifty-seven dental medicine students participated in this study. The median number of teeth in both groups of students was 28 (interquartile range (IQR)=24-32 for he first-year students; IQR=25-32 for the fifth-year students). All first-year students were diagnosed with healthy periodontium, while two fifth-year students had periodontitis and six had gingivitis. The fifth-year students used interdental brushes, mouth rinses and went for professional teeth cleaning more frequently. Logistic regression analysis showed that the fifth-year students had higher PI (odds ratio (OR)=1.157, 95% confidence interval (CI)=1.025-1.306, P=0.018) and BoP (OR=1.466, 95% CI=1.116-1.925, P=0.006).

The questionnaire was dis-tributed to participants using convenience and snowballing sampling strategies. A logistic regression model was used to estimate the association of selected determinants with the demand for voluntary health insurance.Results: A total of 203 participants completed the question-naire (age range 24-42) A statistically significant associa-tion was found between higher insurance policy sales price (odds ratio (OR)=1.016, 95% confidence interval (CI)=1.002-1.031), increased awareness of healthy diet (eating habits) (OR=1.768, 95% CI=1.100-2.841) and buying a voluntary health insurance policy. People in a higher income class (OR=0.594, 95% CI=0.364-0.970) and with a good subjec-tive perception of personal health status (OR=0.454, 95% CI=0.232-0.889) were less likely to buy a voluntary health insurance policy. Also, the demand for voluntary health in-surance decreased with age (OR=0.924, 95% CI=0.873-0.978), with older participants being less likely to buy voluntary health insurance than younger ones.Conclusion: The choice to buy a voluntary health insurance policy largely correlates with an individual’s socioeconom-ic status in today’s society. Older participants with a higher income and good eating habits are less likely to buy a vol-untary health insurance policy.

Methods: In 2017, a tide-gauge station, and a meteorological station have been installed at Stari Grad (Hvar Island, east-ern middle Adriatic Sea). Three years of sea level and at-mospheric measurements were analysed. Ten strongest ep-isodes of the following extreme types were extracted from sea level data: positive long-period (T &amp;gt;210 min) extremes; negative long-period (T &amp;gt;210 min) extremes; short-period (T &amp;lt; 210) extremes.

Results: Positive long-period extremes commonly appeared during the presence of low-pressure atmospheric systems over the Adriatic – such system were accompanied with strong SE winds. Negative long-period extremes were as-sociated with presence of high atmospheric pressure fields over the Adriatic Sea, either with strong NE winds, or calm weather.

We followed the approach of the EC Mutual Learning Exercise on Research Integrity and the country report cards at The Embassy of Good Science.Results: We identified similarities and differences regarding research infrastructure, funding, strategy, research governance, compliance, integrity, regulations, and measures to promote good scientific practices and open science at the country level. The universities that are partners in the SEA-EU Alliance differed in the research capacity, expressed as the number of higher education institutions in the country, number of full-time researchers, gross expenditure on research and development, number of grants as well as in the structures and processes at the institutional and national levels for research ethics and research integrity. The differences in the research ethics and integrity frameworks at individual universities were related to the national legislation but also to the national and institutional incentives to promote responsible research.Conclusions: In collaborative research, it is necessary that partner universities respect the differences between their organizational and national ethical and integrity frameworks, and establish the processes for ethics approval at the level of the Alliance in order to carry out joint research activities in accordance/conformity with ethical standards for scientific research and good scientific and publishing practice.
