Analysis of hospital service areas in Istanbul

After 1950's, the rapid expansion of Istanbul has created tremendous demand for new public facilities as well as the need for evaluation of existing facilities. Although the service areas of hospital is a very important information in order to use efficently scarce resources, there are very few studies on this subject in devoloping countries. This study investigates the spatial behavior of in patients in relation to three different types of hospitals ( teaching, general public and private) in order to provide background for the efficient planning of health facilities in Istanbul. According to the results, all three types of hospitals receive patients from different parts of the city as well as throughout the country. The service areas of these hospitals are investigated also according to their location within the different zones of the city. As the speciality of the hospitals increases, the density of the patients becomes more widely distributed than the local hospitals. According to the results, the areas which are not served by any hospital are determined. Further, research is suggested on more detailed analysis of spatial behavior of patients with respect to patients' characteristics.

Value of the electronic patient record: An analysis of the literature

AbstractWe undertook a systematic review of the literature on the basis of published studies on the benefit and costs of Electronic Patient Records (EPRs) to clarify the issue of whether and to what extent the use of an EPR is worthwhile. We carried out a systematic electronic search for articles published between 1966 and early 2004 using MEDLINE, following up cross-references from the articles found. We searched first for suitable medical subject headings (MeSH) for electronic patient record, benefit and costs. We obtained 7860 citations with the MeSH keyword ‘‘Medical Record System, Computerized”. After combination with appropriate keywords this number was reduced to 588, after a review by two reviewers independently based on abstracts down to 95, and after a further review based on full-text articles to 19 covering 20 studies. The publications evaluated thus document the economic benefits of EPR in a number of areas, but they do not make a statement of the cost effectiveness of EPR in general

Molecular diversity among Turkish oaks (QUERCUS) using random amplified polymorphic DNA (RAPD) analysis

The genus Quercus (Fagaceae) includes the most important woody plants with decidious and evergreen species in Northern hemisiphere. They have a problematic taxonomy because of widespread hybridization between the infrageneric taxa. Turkey is one of the most important region of the world according to oak species number and variation. In this study, species belonging to evergreen oaks in Turkey were investigated to solve taxonomic problems and to design the limit of taxa by using random amplified polymorphic DNA (RAPD) data. Here, three species of evergreen oaks known as Quercus coccifera, Quercus ilex and Quercus aucheri were studied in all area located and made the comparison within and among species studied using ten RAPD markers. As a result; it can be stated that the presence of the three species in Ilex section is clear. Furthermore, existence of two infraspecific taxa or two seperate taxa in species level within Q. coccifera may be quite possibly considered.Key words: Quercus ilex, Quercus coccifera, Quercus aucheri, random amplified polymorphic DNA (RAPD)

Thermodynamic and kinetic assessments of strontium-doped lanthanum manganite perovskites for two-step thermochemical water splitting

Solar-driven thermochemical water splitting using non-stoichiometric oxides has emerged as an attractive technology for solar fuel production. The most widely considered oxide for this purpose is ceria, but the extreme temperatures required to achieve suitable levels of reduction introduce challenges in reactor design and operation, leading to efficiency penalties. Here, we provide a quantitative assessment of the thermodynamic and kinetic properties of La_(1−x)Sr_xMnO_(3−δ) perovskites, targeted for a reduced temperature operation of thermochemical water splitting. Sr-doping into lanthanum manganite increases the thermodynamic fuel production capacity, which reaches 9 ml g^(−1) for 0.4 Sr for a thermochemical cycle operated between 1400 and 800 °C. The hydrogen yields are moreover in good agreement with expected values based on analysis and extrapolation of thermogravimetric data available in the literature. High levels of Sr doping, however, result in low steam-to-hydrogen conversion rates, implying high energy penalties in an operational reactor. Furthermore, the rate of fuel production decreases with increasing Sr content, suggesting that intermediate compositions may yield the most suitable combination of properties

Phase Diagrams and Crossover in Spatially Anisotropic d=3 Ising, XY Magnetic and Percolation Systems: Exact Renormalization-Group Solutions of Hierarchical Models

Hierarchical lattices that constitute spatially anisotropic systems are introduced. These lattices provide exact solutions for hierarchical models and, simultaneously, approximate solutions for uniaxially or fully anisotropic d=3 physical models. The global phase diagrams, with d=2 and d=1 to d=3 crossovers, are obtained for Ising, XY magnetic models and percolation systems, including crossovers from algebraic order to true long-range order.Comment: 7 pages, 12 figures.

Growth and Demography in Turkey: Economic History vs. Pro-Natalist Rhetoric

This paper projects the effects of exogenous fertility changes in Turkey on the age structure of population and the standards of living using a semi-reduced-form model of economic growth and demographic change. Both the technological progress and the fertility rate are endogenous. The calibrated version of the model delivers three important results: First, technological progress will be the major source of economic growth in Turkey in the upcoming decades. Second, even with a non-declining saving rate, the population aging will result in a growth slowdown since technological progress is not fast enough in Turkey. Third, even under an increasing rate of technological progress, a permanent upward shift in fertility levels would imply, relative to the benchmark, a significantly lower level of output per capita, a remarkably higher level of dependent population, and a persistently lower share of the working-age population for many decades. These results suggest that the priority of policy-makers in Turkey should be technological progress. The pro-natalist rhetoric, even if it proves to be strong enough to persuade the people of Turkey to have more children in the near future, does not have any economic significance
