Financing of health services and alternative methods: some suggestions
No full textPresenting Health Care should have priority because of importance of health care for individuals and society. Today, with understanding importance of this point different political ideas and economic ideas put a lot of effort to increase the individual’s productivity and average life expectation and improve investments on humanity. Even so, sometimes statistics on health services can be critter of structure of modern countries. (Average life expectation, percentage of baby death etc.) Providing effective and fair health service which is important as such as life itself limited to cost and question of finding the right sources to cover the cost. Slow economic growth, increasing unemployment, fast growing population are the main factors of increased cost of health services and those factors are appears as actual reasons of financial difficulties on agenda. Financial difficulties of health services will affect to quality and amount of services and also will be the main reason to bring out different methods of practice. But despite those differences, to provide quality health services to the individuals requires strong and continual financial sources. Financial difficulties of health services will affect to the services for individuals so therefore will effect to individuals health. So this essay originated from those important points, aims to explore the financial difficulties throughout historical development and at the same time will look for improvement and alternative managements.Health care services, financing and alternative methods
Cyclic admissible contraction and applications to functional equations in dynamic programming
No full textIn this paper, we introduce the notion of T-cyclic (alpha,beta)-contraction and give some common fixed point results for this type of contractions. The presented theorems extend, generalize, and improve many existing results in the literature. Several examples and applications to functional equations arising in dynamic programming are also given in order to illustrate the effectiveness of the obtained results
Thermoluminescence characteristics of calcite with a Gaussian process regression model of machine learning
No full textIsik, Esme, Department of Optician, Malatya Turgut Özal University, Malatya, TurkeyReceived: 22 February 2022. Revised: 20 April 2022. Accepted: 27 May 2022.© 2022 John Wiley & Sons Ltd.Correspondence, Esme Isik, Department of Optician, MalatyaTurgut Özal University, Malatya, Turkey.Email:[email protected] known as:Journal of Bioluminescence and ChemiluminescenceThermoluminescence (TL) is defined as a luminescence phenomenon that can be detected when an insulator or semiconductor is thermally stimulated. Defective crystals store radiation until they are stimulated. Thermoluminescence is a method of monitoring the absorbed dose of dosimeters. The irradiation crystal is heated to 500°C to display the absorbed dose as a luminescent light. The TL dosimetric properties of calcite obtained from nature were investigated in this study. Machine learning was also examined using Gaussian process regression (GPR) for stimulated TL characteristics. According to the experimental output, the TL glow curve had two main peaks located at 90°C and 240°C with good dosimetric properties. In the four regression models of GPR, the data for the heating rate of 3°C s-1 have the lowest residual
Determination of optical parameters of Ga0.75In0.25Se layered crystals
No full textGasanly, Nizami/0000-0002-3199-6686; Gasanly, Nizami/0000-0002-3199-6686; Isik, Mehmet/0000-0003-2119-8266The optical properties of the Ga0.75In0.25Se crystals have been investigated by means of transmission and reflection measurements in the wavelength range of 380-1100 nm. The analysis of the results performed at room temperature revealed the presence of optical indirect transtions with band gap energy of 1.89 eV. The variation of the band gap energy as a function of temperature was also studied in the temperature range of 10-300 K. The rate of change of band gap energy (? = 6.2 x 10(4) eV/K) and absolute zero value of the band gap (Egi(0) = 2.01 eV) were reported. The wavelength dependence of the refractive index was analyzed using Wemple and DiDomenico, Sellmeier and Cauchy models to find the oscillator energy, dispersion energy, oscillator strength and zero-frequency refractive index values.

A rational approximate solution for generalized pantograph‐delay differential equations
No full textIsik, Osman Rasit/0000-0003-1401-4553WOS: 000377112400007In this paper, a new rational approximation based on a rational interpolation and collocation method is proposed for the solutions of generalized pantograph equations. A comprehensive error analysis is provided. The first part of the error analysis gives an upper bound for the absolute error. The second part is based on residual error procedure that estimates the absolute error. Some numerical examples are given to illustrate the method. The theoretical results support the numerical results. Copyright (c) 2015 John Wiley & Sons, Ltd

φ-Best proximity point theorems and applications to variational inequality problems
No full textThe main concern of this study is to introduce the notion of φ-best proximity points and establish the existence and uniqueness of
φ-best proximity point for non-self mappings satisfying (F,φ)-proximal and (F,φ)-weak proximal contraction conditions in the context of complete metric spaces. Some examples are supplied to support the usability of our results. As applications of the obtained results, some new best proximity point results in partial metric spaces are presented. Furthermore, sufficient conditions to ensure the existence of a unique solution for a variational inequality problem are also discussed
Money Supply Function for Bangladesh: An Empirical Analysis
No full textThe study had empirically tested the money supply function for Bangladesh using annual time series data. Authors observed that high-powered money played a very significant role in the money supply process of Bangladesh, particularly with respect to the narrow money supply M1, thus providing some support for the monetarist model. However, beyond the monetarist view, additional variables in the light of the Keynesian and structuralist analysis, such as bank rate, external resources, and financial liberalization need to be taken into account in understanding the money supply process of the country. Other aforesaid variables were also found to exert some influence on the broad money supply in Bangladesh. However, given the poor performance of the narrow money model and the existence of multicollinearity problem in both models, the estimated results, even for the broad money model, needed to be interpreted with caution.
Bernstein series solution of linear second-order partial differential equations with mixed conditions
No full textIsik, Osman Rasit/0000-0003-1401-4553WOS: 000332952300001The purpose of this study is to present a new collocation method for numerical solution of linear PDEs under the most general conditions. The method is given with a priori error estimate. By using the residual correction procedure, the absolute error can be estimated. Also, one can specify the optimal truncation limit n, which gives better result in any norm parallel to parallel to . Finally, the effectiveness of the method is illustrated in some numerical experiments. Numerical results are consistent with the theoretical results. Copyright (c) 2013 John Wiley & Sons, Ltd
