The quantity and quality of women's employment has long been a worldwide issue and has particular resonance in Turkey. In Turkey, the banking sector is of particular significance due to its high number of female employees. Thus, owing to this phenomenon, the main focus of the chapter is on the banking sector. One of the greatest problems facing working women in life is work-family conflict, kind of role conflict. Furthermore, in recent years, organizational cynicism has long been a central plank in many studies. This study thus examines women's conflict with work and family life along with organizational cynicism and its numerous lower dimensions. Data gathered from 182 female bankers was analyzed using SPSS (Statistical Program of Social Sciences) software. Analysis of the results would suggest that some demographic variables have a significant impact upon organizational cynicism and the conflict between work and family life conflict. Also, there is a positively significant correlation in medium level between the variables.

The analysis of the problem of calculating the bearing capacity of structures, taking into account the guaranteed level of reliability and failure-free operation, was carried out. On the basis of the works of N. N. Streletsky, A. R. Rzhanits and others, bottlenecks are established that do not make it possible to design structures with a guaranteed level of reliability and failure-free operation, despite the introduction of the concept of strength class and the existing reliability theory. According to the failure-free operation indicator, a scheme for normalizing the reliability of designed building structures is proposed and is interrelated with the assessment of the quality of structures being built. Guaranteed design quality indicators with a set probability of failure-free operation that are not related to strength are introduced: geometric dimensions, modulus of deformation and elasticity, taking into account the variability of properties and technology. The corresponding reserve coefficients ensuring the required probability of failure-free operation are determined. The scheme for calculating the design of structures with the required level of reliability is developed in the process of design, construction and operation of structures, taking into account the completeness and reliability of information on the results of quality control, during operation, taking into account the reduction of physical, mechanical and other properties of structures.

Maintainability is one of the most important quality attribute that affect the quality of software. There are four factors that affect the maintainability of software which are: analyzability, changeability, stability, and testability. Open source software (OSS) developed by collaborative work done by volunteers through around the world with different management styles. Open source code is updated and modified all the time from the first release. Therefore, there is a need to measure the quality and specifically the maintainability of such code. This paper discusses the maintainability for the three domains of the open source software. The domains are: education, business and game. Moreover, to observe the most effective metrics that directly affects the maintainability of software. Analysis of the results demonstrates that OSS in the education domain is the most maintainable code and cl_stat (number of executable statements) metric has the highest degree of influence on the calculation of maintenance in all three domains.

This paper presents a methodology for evaluating the failure probability of fluid bearings, which are sensitive components for the design of machine rotors, mechatronic systems, and high precision metrology. The static and dynamic behavior of a fluid bearing depends on several parameters, such as external load, bearing dimensions, supply pressure, quality of the machined surfaces, fluid properties, etc. In this paper, the characteristics of a simple geometry hydrostatic bearing are calculated analytically in order to demonstrate the usefulness of the methodology and its pertinence to bearing design. Monte Carlo simulation and first order reliability method (FORM) are used to evaluate the probability of failure.

In the issue of futile treatments, patients and healthcare professionals tend to disagree. We conducted an Internet questionnaire survey and explored the Japanese nurses’ attitude toward this topic, comparing with that of laypeople. In total, 522 nurses and 1134 laypeople completed the questionnaire. Nurse respondents were significantly less in favor of providing potentially futile treatments in hypothetical vignettes and stressed quality of life of the patient for judging the futility of a certain treatment. Of them, 85.4% reported having experienced providing such treatments. Reasons for providing them included factors related to not only patients but also healthcare teams. Our results indicate that attitudes among Japanese nurses toward the issue of futile treatments are different from patients and that their actual practice is influenced by several situational factors.

The safety evaluations of structures are usually performed by assuming uncertain 18 input parameters either as probabilistic or possibilistic in nature. Safety evaluations of structural systems characterized by some of the input parameters as possibilistic and others that are sufficient enough to model as probabilistic are unsuitable and restricted to gross assumption at early stages of modeling. The present paper deals with the safety analysis of such a hybrid uncertain system. Relying on the fundamental concept of entropy-based transformation; the feasibility of reliability analysis of a hybrid uncertain system in a possibilistic format is demonstrated in the present study. This will enable the designers to model the structural parameter uncertainty probabilistically as well possibilistically depending on the nature and quality of the input data. The bounds on the probability of failure based on the evidence theory are also computed to study the consistency of the possibility of failure results obtained by the transformation-based algorithm. A numerical example illustrates the capability of the proposed possibilistic approach of safety evaluation of hybrid uncertain system.

The Michaelis-Menten equation is one of the various techniques available for predicting steady-state plasma levels of phenytoin. In actual practice, however, data are not always available or reliable. This case report emphasizes the importance of establishing the quality of the data and determining that steady state has been achieved. The addition of a third point to the graph used to estimate parameters greatly increases prediction accuracy.

Background: While the system of registration of mortality and cause of death (COD) in Greenland was established several decades ago, reporting procedures follow a complicated administrative process. Timely and reliable reporting on mortality and COD is of high importance for the usability of the collected data for research, health planning and decision making. Methods: COD data collected by the Chief Medical Office in Greenland from 2006 to 2015 (4490 registered deaths) were analysed with the software Analysis of National Causes of Death for Action (ANACONDA) v4.0. Unusable or insufficiently specified ICD codes are identified. The Vital Statistics Performance Index for Quality (VSPI(Q)) is estimated for the overall quality conclusions of the register’s usability. Results: Sixty-eight per cent of the input data for Greenland was coded with a usable underlying COD, 24% with an unusable cause and 8% of deaths with an insufficiently specified cause. Almost 700 deaths were coded to an unusable code of ‘very high impact’. The most prevalent unusable underlying causes were other ill-defined and unspecified causes, including no death certificate available, followed by senility, heart failure, sepsis and shock and cardiac arrest. The VSPI(Q) score was 66%, representing medium quality. Conclusions: In the 10 years’ worth of data analysed, the true underlying COD in many cases was unknown. Several likely explanations for this include lack of systematic COD training for physicians, logistic and capacity challenges in Greenland that potentially could reduce the quality of the collected data and its usability in providing essential information about the true pattern of mortality in Greenland.
