    Determinants of Out of Pocket Health Expenditure in Turkey: Unconditional Quantile Regression

    Ipek, Egemen

    Out-of-pocket health expenditures include direct and indirect payments made by individuals for health goods and services. In this study, the determinants of out-of-pocket health expenditures, which are one of the most important sources of health expenditures financing, are investigated with the data of 2003-2015 Household Budget Survey using the Unconditional Quantitative Regression method proposed by Firpo et al. (2009). This method allows to produce generalizable and interpretable results in terms of political and general society compared with conditional quantitative regression methods. The most important result obtained from the study is that conditional quantitative regression method gives more consistent results than unconditional quantitative and least squares regression methods in the analyzes based on the right-skewed distribution observations such as out-of-pocket health expenditures.

    Çakir, Gunay; Kaya, Latif Gurkan; Yücedag, Cengiz; Bayram, Sitki

    Aim of study: This study is done to monitor temporal land use/land cover changes in a typical mountain watershed covering an area of 135441.0 ha in North Eastern of Turkey based on rural demographic dynamics and forest management plans belonging to the years 1987 and 2013 coupled by GIS analyses. It also investigates changes in the shape of land use class (LUC) over the period. Material and Methods: The changes occurring time wise and positional on the base of the local LUC was examined by benefiting from the forest management plans from 1987 to 2013. Moreover, the change of LUC around these areas has been examined with the 1000 m zones thrown around the settlement areas and correlated with the fast decrease of the population recent years. Demographic dynamics (increase or decrease) affect the usage of forest lands, as well. Main results: While there was an increase in the productive forest lands (pure coniferous and deciduous, and mixed forest) between 1987 and 2013. In the same periods there was a decrease in agricultural and sandy areas. The increase of patches in the productive forest lands mostly resulted from afforestation works conducted in the unproductive forest lands, and forestry maintenance activities. Another reason for this increase of forest patches is why people have immigrated to urban areas in the last years. Research Highlights: It can be said that one of the most important causes in the rise of the forest resources in the Alucra Forest Planning Units (FPU) is the time wise changes of social structure. Furthermore, the forestry activities in the study between 1987 and 2013 are also the other significant factor in this increase of forest resources.

    Some Physical and Mechanical Properties of Impregnated Chestnut Wood with Natural and Chemical Agent Exposed to Outdoor Conditions

    Yasar, Mehmet; Altunoiv, Mustafa

    Wood preservatives have been widely used to extend the service life of wood. The most objectionable environment for wood is outdoor conditions. In this study, test specimens prepared from chestnut wood (Castanea sativa Mill) were impregnated with natural and chemical impregnation agent. It was aimed to determine the effect of outdoor conditions on physical and mechanical properties of wood material by keeping them under these conditions for one year. As natural impregnation material pine tannin and acorn tannins, as chemical impregnation material imersol aqua and timbercare aqua were used. The retention amount, air-dried density, bending strength, modulus of elasticity, compression strength parallel to fibers, adhesion strength parallel to fibers, screw withdrawal strength were determined. As a result, it can be said that the physical and mechanical test values can compare wood impregnated with natural impregnation materials to wood impregnated with chemical impregnation materials after one year exposed to outdoor conditions.

    DETERMINING THE RELATIONSHIP BETWEEN POSTOPERATIVE PAIN AND THE RISK OF FALLS IN OLDER ADULTS

    Sayilan, Aylin Aydin; Kulakaç, Nursen; Saltan, Asuman

    Introduction: Pain and falling are substantial components of older adults' life. Despite the presence of several plausible mechanisms for pain to contribute to falling, very few studies have investigated this relationship in older adults. This study was designed to determine the relationship between falls associated and postoperative pain in surgical patients aged over 65 years. Material and methods: This cross sectional and descriptive study was conducted at a public hospital between January and June, 2018. The study population consisted of postoperative patients aged 65 years and over, hospitalised in the Urology, General Surgery, and Orthopaedic clinics between the study dates. After demographic knowledge was collected, the Itaki Fall Risk Scale and Visual Analogue Scale were used for the risk of falling and pain level assessments, respectively. Results: The mean age of the participants was 72.14 +/- 8.85 years. A statistically significant relationship was observed between pain levels and the risk of falling in the postoperative period (rho = 0.000). The risk of falling increased in line with pain levels. Patients who were single (rho = 0.01), who had no social security (rho = 0.002), and with chronic disease had a significantly higher risk of falling (rho = 0.003). Conclusions: Pain in older adults may increase the risk of falling after surgery. In clinical and academic studies, it is recommended that pain assessments be included in older adults for the risk of postoperative fall.

    Saglam, Mehmet; Avci, Ibrahim

    Product placement efforts are expected to result in more desirable brand experiences and awareness as a result of consumers' brand experiences. The attitude towards product placement increases the brand experience and makes the brand more permanent in our memory. In this study, it is aimed to examine the mediating role of the brand experience in the effect of attitude towards product placement on brand awareness. The research was carried out on Fi series audiences, where product placements were frequently used. The convenience sampling method was used, and an online survey form was used as data collection tool. 173 participants were reached during the data collection process. SPSS 21, AMOS 20 and PROCESS 3.1 programs were used for data analysis. The parallel multivariate mediator model was used to examine the mediator role of brand experience dimensions. As a result of the study, it was determined that the attitude towards product placements had an effect on brand awareness and brand experience dimensions, and the greatest effect was on the sensory experience. When the mediator roles are examined, it is concluded that the sensory and behavioral brand experience has a full mediating role in the effect of attitude towards product placements on brand awareness, and the mediator effect of the behavioral brand experience was higher.

    Kalkisim, Ozgun; Ozdes, Duygu; Baltaci, Cemalettin; Duran, Celal

    The present study aims to identify the heavy metal contents of white mulberry (Morus alba L.) and black mulberry (Morus nigra L.) that are grown in the city center of Gumushane province and its neighboring counties. Heavy metal analyzes were performed in the fruits, leaves and soils of the plants. The control samples, on the other hand, were collected from the mulberry trees located 3 km away from the highway where the vehicle traffic and industrial activities are at their lowest. Sample collection was performed twice a year, namely during the ripening period and fully ripening period of the fruits. The analyses of the heavy metals were performed by using inductively coupled plasma-mass spectrophotometry (ICP-MS). The obtained results were compared with the acceptable limits of heavy metal for humans as established by the World Health Organization (WHO), Turkish Food Codex (TFC) and the literature and an opinion was submitted as to whether they present any risk in terms of human health. When the available data is evaluated, the mulberries grown in Gumushane province, were found to have presented a health risk in terms of Pb, Cd, Ni, Cu, Zn, Mn and Co metals.

    Psychrotolerant bacteria isolated from the leaf apoplast of cold-adapted wild plants improve the cold resistance of bean (Phaseolus vulgaris L.) under low temperature

    Tiryaki, Deniz; Aydın, İhsan; Atıcı, Ökkeş

    We have isolated psychrotolerant bacteria from the leaf apoplast of cold-adapted wild plants and aimed to investigate their effect on the cold resistance of bean (Phaseolus vulgaris L.). Based on the findings of 16S rRNA gene sequence analysis, 20 isolates belonging to 5 bacteria species (Pseudomonas fragi, P. chloropaphis, P. fluorescens, P. proteolytica and Brevibacterium frigoritolerans) were identified in the leaf apoplastic fluid of Draba nemorosa, Galanthus gracilis, Colchicum speciousum, Scilla siberica, Erodium cicutarium, respectively. We have determined that 6 of the 20 isolates have exhibited ACC (1-aminocyclopropane-1-carboxylate) deaminase activity and secreted different extracellular proteins under cold condition (+4 °C) compared to normal growth condition (28 °C). The six isolates were then inoculated independently of each other to the leaves of 10-day-old bean seedlings growing under normal conditions (25/22 °C, 16/8 h photoperiod), and the inoculated and uninoculated (control) seedlings were transferred to cold (9/5 °C, 16/8 h photoperiod) for 3 days. The bacterial inoculations have decreased freezing injury, ice nucleating activity and lipid peroxidation content in parallel with the decrease of reactive oxygen species level such as O2.- and H2O2 in the inoculated seedlings compared to the control. In addition, the inoculations of the isolates have stimulated the activity of apoplastic antioxidant enzymes including superoxide dismutase, catalase, peroxidase, and glutathione reductase. The results show that the inoculations improve the cold resistance of bean seedlings and the psychrotolerant bacterial isolates can be evaluated within the group of plant growth promoting bacteria (PGPB) which can increase tolerance of cold-sensitive crops.

    Realization of a low cost and fast boost converter based MPPT for PV system

    Basoglu, Mustafa Engin

    Photovoltaic (PV) modules have a small power conversion efficiency since material technologies used in commercial PV modules is weak and not well developed. In order to provide the maximum available efficiency in a PV module, a power processing unit (PPU) is connected between PV module and load to extract more power from PV modules In other words, DC-DC converters are used for impedance matching between PV module and load in any kind of loading and environmental conditions. Several maximum power point tracking (MPPT) algorithms have been proposed in the literature. But there are still shortcomings to be improved such as reducing the steady state ripples in power, dynamic response time under changing conditions. In this paper, design steps of the boost converter for an MPPT application have been presented and some experiments have been performed. Consequently, a low cost and fast boost converter based MPPT is implemented.

    Ethical sensitivity, burnout, and job satisfaction in emergency nurses

    Palazoğlu, Cansu Atmaca; Koç, Zeliha

    Background: Rising levels of burnout and decreasing job satisfaction can inhibit healthcare professionals from providing high-quality care due to a corresponding decrease in their ethical sensitivity. Aim: This study aimed to determine the relationship between the level of ethical sensitivity in emergency service nurses and their levels of burnout and job satisfaction. Research design: This research employed a descriptive and cross-sectional design. Participants and research context: This study was conducted with a sample of 236 nurses, all of whom worked in emergency service between 24 July 2015 and 28 April 2016. Data were collected using the Moral Sensitivity Questionnaire, Maslach Burnout Inventory, and Minnesota Job Satisfaction Scale. Ethical considerations: This study was approved by the Institutional Ethics Review Board of Ondokuz Mayıs University. Findings: There was a weak and negative correlation (r = –0.158, p = 0.015) between Moral Sensitivity Questionnaire and Maslach Burnout Inventory scores. There was also a weak and negative correlation (r = –0.335, p < 0.001) between the Maslach Burnout Inventory and Minnesota Job Satisfaction Scale scores. Discussion and conclusion: Decreased job satisfaction and increased burnout levels among emergency service nurses might result in them indulging in improper practices, frequently facing ethical problems, and a decrease in the overall quality of service in hospitals. In order for emergency service nurses to recognize ethical problems and make the most accurate decisions, a high level of ethical sensitivity is critical. In this respect, it is suggested that continuing education after graduation and training programs should be organized.

    İlyasoğlu, Huri; Yilmaz, Fırat

    This study aimed to evaluate the physicochemical, chemical, rheological, sensorial and microbiological properties of yoghurt enriched with polyunsaturated fatty acids (PUFAs). The PUFA-enriched yoghurt was prepared with walnut slurry (10%−50%) and skimmed milk (50%−90%). Compared with the control yoghurt, it contained a lower content of protein, potassium, sodium and phosphorus, and a higher content of fat, iron, magnesium and zinc. Moreover, it exhibited a lower syneresis value and a higher water-holding capacity value. Its fat was rich in omega fatty acids, mainly linoleic and linolenic acids. These research findings revealed that walnut slurry could be used in yoghurt manufacture to develop fermented milk products as functional foods, especially when enriched with omega fatty acids.

    Adiguzel, Gulsah; Faiz, Ozlem; Sisecioglu, Melda; Sari, Bilge; Baltaci, Ozkan; Akbulut, Sumeyya; Genc, Berna; Adiguzel, Ahmet

    A novel extracellular xylanase was purified and characterized from Pediococcus acidilactici GC25 (GenBank number: MF289522). The purification was 4.6-fold with a yield of 43.61% through acetone precipitation, Q-Sepharose, and CM-Sepharose ion change chromatography. The molecular weight of the enzyme was 48.15 kDa, and the optimum pH and temperature were 7.0 and 40 °C, respectively. The maximum activity was observed between 20 and 50 °C. Although it was active within a wide pH range (pH 2.0–9.0), it retained over 85% of its activity after 24 h incubation; and over 70% of its activity after 168 h incubation in neutral and alkaline pH. It was observed that the enzyme showed high stability with K+, Ba2+, Cd2+, Co2+, Sr2+, Mg2+, Ca2+, Al3+, Zn2+, and Ni2+ ions. The Km and Vmax for the xylanase were 3.10 mg mL−1 and 4.66 U/mg protein, respectively. It was determined that treatment of different fruit juices with P. acidilactici GC25 xylanase improved the clarification. The highest increase in the reducing sugar amount and decrease in the turbidity was 24.47 ± 1.08 and 21.22 ± 0.58 for peach juice at 0.15 U/mL enzyme concentration. These results showed that the xylanase purified from P. acidilactici GC25 may have a wide potential in biotechnological processes of the food and baking industry.

    Nature of tourmaline formation in quartz porphyry in the E Sakarya zone (NE Turkey): Geochemistry and isotopic approach

    Sipahi, Ferkan

    Tourmaline, which exhibits important differences in terms of texture and composition, is found in 44 My aged quartz porphyry from Karadağ in the eastern Pontide (NE Turkey). Tourmaline has high Al and Mg contents and is the chemical zoning; it contains Mg that can substitute for Fe and/or Al in the Y site and X-vacancy that can replace Na in the X site from the core to rim. Tourmaline, classified as dravite component, has low Fe content and very low Ca content. The V (112-510 ppm) and Sr (37.3-147.1 ppm) contents of tourmalines related to quartz porphyry are in conformity with metamorphic and magmatic tourmalines. Tourmalines have similar rare earth elements (REEs) but lower heavy REE contents than host quartz porphyry. The δ18O and δD values of tourmalines are relatively narrow, ranging from 5.7 to 8.5% V-SMOW and from -58 to -72% V-SMOW, respectively, consistent with primary magmatic water. The oxygen-isotope thermometry calculation of quartz and tourmaline pair yields equilibrium formation temperature of 432 °C. The formation of tourmaline shows a post magmatic origin, confirming magmatic fluid cooling and fluid-rock interactions.

    A SEQUENTIAL APPROACH BASED DESIGN OF MULTIPLE TUNED MASS DAMPERS UNDER HARMONIC EXCITATION

    Kahya, Volkan; Araz, Onur

    This study evaluates the response reduction effect of single-degree-of-freedom (SDOF) primary systems with multiple tuned mass dampers (MTMDs) under harmonic excitation. To design MTMD, TMD properties are re-calibrated based on the natural frequencies of the system on which the number of TMDs is one less than the current system. This is a sequential approach that does not require any iteration for each step. Instead it requires starting from the case with single TMD, and then increasing the numbers of TMDs one more at a time until the desired number is reached. Using the obtained design parameters, the effectiveness and robustness of the MTMDs are studied in comparison to MTMDs designed by previous works available in the literature. As a result, the proposed design procedure produces an effective multiple tuned mass damper to be utilized in a SDOF system under harmonic excitation. Additionally, the proposed approach provides a simple way to design the MTMD system than the traditional optimization methods, thus it significantly reduces the computation effort in the design process.
