Sickness absence in Troms County. Trends and risk factors

This thesis examines the dynamics of the sickness absence in Troms county. High level of sickness absence in Norway causes substantial costs for sick pay scheme and replacement workers likewise significant reduction in productivity. Awareness of the trends of sickness absence and the risk factors which increase the likelihood of sick leave contributes to the establishment of proper policies aimed to reduce it. Until now the measures did not show expected efficiency. My method of analysis is a combination of descriptive statistics and regression analysis performed by using RStudio software (RStudio, 2015). I examined the relationship between variables day of week, month, year, mean temperature, sum of precipitation and wind power, gender, sector, age and profession and the frequency of the registered sick leaves in Troms county for the period 2010-2017. Key findings are: 1) the sickness absence showed pronounced seasonality and steadily growth during the estimated period, 2) weather describing variables did not show significant effect on the frequency of sick leaves, 3) women have more sickness absence than men, 4) municipality sector has the highest sickness absence rate, followed by private and governments sectors, 5) younger population showed significant ongoing increase in sickness absence compared to older population, 6) significant changes in the economy reflecting on GDP cause fluctuations and deviations from the general trend of sickness absence in all sectors, age and profession groups

A CRUD extension to a path based testing algorithm

Testování softwaru hraje klíčovou roli při zajišťování kvality a spolehlivosti systému v průběhu celého vývojového cyklu. Zajištění kvality aplikace obvykle zahrnuje ověření jejího chování na základě předem definovaných požadavků prostřednictvím vytvoření a spuštění testovacích případů. Jak se však systémy stávají složitějšími, tradiční testovací techniky se potýkají s problémy při vytváření přesných testovacích případů kvůli různorodým uživatelským prostředím, složitým interakcím systému a optimalizaci výkonu. Model-based testing tyto problémy řeší nahlížením na testovací systém jako na model, který abstrahuje jeho očekávané chování. Ačkoliv nástroje pro generování testovacích případů pomocí této techniky existují, například Oxygen nebo GraphWalker, neumožňují nám do modelu zahrnout požadavky na data. To vede k tomu, že se v testovacím případě objevují kombinace kroků, které v reálném světě nemohou nastat. Následně se celý testovací případ stává neproveditelným, což vede ke snížení efektivity testování. Tato práce vychází z konceptu Negative Constrained Path-based Testing a zavádí nový algoritmus, který integruje constrainty do modelu systému, aby se zabránilo generování nesplnitelných testovacích případů. Poté se výsledky algoritmu hodnotí ve srovnání s výsledky algoritmu Oxygenu, přičemž zaměřuje na metriky jako je optimalita a snížení počtu nesplnitelných testovacích případů. Diplomová práce se zaměřuje na omezení existujících testovacích technik pomocí zavedení constraintů a klade si za cíl zlepšit stávající přístupy v testování softwaru zajištěním spolehlivějších výsledků testů.Software testing plays a crucial role in ensuring the quality and reliability of the system through the whole development cycle. Quality assurance of the application usually involves verifying its behaviour against predefined requirements through the creation and execution of test cases. However, as systems become more complex, traditional testing techniques face challenges in generating accurate test cases due to diverse user environments, complex system interactions, and performance optimization. Model-based testing addresses these challenges by representing the System Under Test as a model that abstracts its expected behaviour. While several tools exist for test case generation using model-based testing, such as Oxygen or GraphWalker, they do not allow us to incorporate data requirements in the model. It leads to appearing in test case step combinations that cannot happen in the real world, making the whole test case infeasible. Such test cases reduce the effectiveness of the testing process, resulting in wasted resources that could be allocated elsewhere. Based on the concept of Negative Constrained Path-based Testing, this thesis introduces a novel algorithm that integrates constraints to prevent the generation of infeasible test cases. This approach enhances the existing methods by addressing data requirements in system models. The thesis details the development and analysis of this algorithm. Furthermore, it evaluates the results obtained using the developed algorithm against the ones obtained from Oxygen, focusing on metrics such as accuracy, optimality, and the number of infeasible test cases. By addressing the limitations of existing testing techniques using constraints, this research aims to advance software testing practices by ensuring more reliable testing outcomes

No association between genetic markers and hypertension control in multiple cross-sectional studies.

We aimed to assess whether genetic markers are associated with hypertension control using two cross-sectional surveys conducted in Lausanne, Switzerland. Management of hypertension was assessed as per ESC guidelines using the 140/90 or the 130/80 mm Hg thresholds. One genetic risk score (GRS) for hypertension (18 SNPs) and 133 individual SNPs related to response to specific antihypertensive drugs were tested. We included 1073 (first) and 1157 (second survey) participants treated for hypertension. The prevalence of controlled participants using the 140/90 threshold was 58.8% and 63.6% in the first and second follow-up, respectively. On multivariable analysis, only older age was consistently and negatively associated with hypertension control. No consistent associations were found between GRS and hypertension control (140/90 threshold) for both surveys: Odds ratio and (95% confidence interval) for the highest vs. the lowest quartile of the GRS: 1.06 (0.71-1.58) p = 0.788, and 1.11 (0.71-1.72) p = 0.657, in the first and second survey, respectively. Similar findings were obtained using the 130/80 threshold: 1.23 (0.79-1.90) p = 0.360 and 1.09 (0.69-1.73) p = 0.717, in the first and second survey, respectively. No association between individual SNPs and hypertension control was found. We conclude that control of hypertension is poor in Switzerland. No association between GRS or SNPs and hypertension control was found

Hydrazides in the Processes of Extraction of Non-ferrous Metals from Ammonia Solutions

The extraction of copper and other non-ferrous metals from ammonia solutions with hydrazides оf Versatic acids (C15–C19 fraction) is discussed in this article. Hydrazide group has been known to be a selective extractant for non-ferrous metals. Introducing the alkyl radical of -branched tert-carboxylic acids into the reagent structure may lead to new properties important for an extractant, such as chemical stability and good compatibility with solvents properties. The optimal extraction conditions, the effect of ammonium salts and the regularities of re-extraction are assessed. Keywords: extraction, hydrazides,  -branched tert-carboxylic acids, non-ferrous metal

Development of Parental Competence Trough Psychological and Pedagogical Support for Families in the Upbringing of Hearing-Impaired Children

Background. Te need for psychological and pedagogical support for families in the upbringing of hearing-impaired children makes it imperative to develop innovative methods and an efective model of interaction between the family and a special needs educational institution, to improve parental competence. Objective. To study the psychological content of parental competence (its cognitive, value-motivational; emotional and behavioral components) and to evaluate parental competence through psychological and pedagogical support for families in the upbringing of hearing-impaired children. Design. Eighty-seven families with hearing-impaired children from a special needs educational institution in Kursk, Russian Federation, participated in the experimental study. Te researchers took measurements at two time points, baseline and followup. At baseline, we made a diagnostic assessment of the psychological content of parental competence. At followup, we evaluated the development of parental competence resulting from the psychological and pedagogical support for these families. Results. Te cognitive component was characterized by predominant unanimity between the parents in the upbringing of hearing-impaired children, and a partnership relationship in communicating with them. Te emotional component was represented by the absence of difculties in understanding the causes of the children’s emotional state and an orientation towards the child’s emotional state during interactions or physical contact. Terminal values (such as health, happy family life) and instrumental values (such as responsibility, honesty) were predominant in the value-motivational component. Te behavioral component displayed a predominance of the authoritative style in upbringing, whereby parents realized their important role in the development of a child’s personality and recognized the right of children to self-development. At the same time, the authoritarian style was still signifcant. Conclusion. A model for psychological and pedagogical support of families in the upbringing of hearing-impaired children was developed, tested, and found to be efective
