Hayta, Sukru; Tasar, Neslihan; Kiran, Yasar; Baser, Birol
Centaurea derderiifolia Wagenitz., Centaurea drabifolia Sm. subsp. floccosa (Boiss.) Wagenitz & Greuter and Centaurea kotschyi (Boiss. & Heldr.) Hayek var. floccosa (Boiss.) Wagenitz, which are endemic taxa from Turkey belonging to Centaurea sect. Cheirolepis, were subjected to morphological, karyological and palynological investigations. The somatic chromosome numbers, pollen morphology and detailed morphometric properties were examined. The somatic chromosome numbers were determined as 2n = 2x = 36 in C. derderiifolia, C. kotschyi var. floccosa, and C. drabifolia subsp. floccosa. Karyotype analysis indicated that chromosomes of these Centaurea taxa generally have median region (m), submedian region (sm) and rarely median point (M) karyotypes. The pollen morphology of these endemic taxa of the genus Centaurea was investigated by light and scanning electron microscopy. The pollen grains of the examined species are mainly isopolar and radially symmetric, subprolate, tricolporate. Tectum ornamentation is scabrate and scabrate-perforate, amb triangular. The pollen grains of all taxa studied are 3-zonocolporate. The colpus is usually long, acute at ends and with smooth membrane. Pollen grains belonging to Cheirolepis section reveal homogeneity in their characters.

The improved Bernoulli sub-equation function method is used in extracting some new exponential function solutions to the (2+1)-dimensional Broer-Kaup-Kupershmidt system. It is of vital effort to look for more solutions of the (2+1)-dimensional Broer-Kaup-Kupershmidt system, which are very helpful for coastal and civil engineers to apply the nonlinear water models in a harbor and coastal design. All the obtained solutions satisfied the (2+1)-dimensional Broer-Kaup-Kupershmidt system. The two-and three-dimensional shapes of all the obtained solutions in this paper are also presented. All the computations and the graphics plots in this study are carried out with the aid of the Wolfram Mathematica 9.

The Apiaceae family includes a few agronomic and medicinal species, one of which is Scaligeria lazica Boiss. In this study, the genetic diversity of S. lazica was analyzed based on novel simple sequence repeat (SSR) markers using next-generation sequencing (NGS). A total of 15.17G clean Illumina data set was obtained and dinucleotide repeats were the most abundant repeats in S. lazica. Of the tested 150 SSR primer pairs, 139 ones produced amplification and 84 ones were polymorphic. Forty polymorphic SSR loci were used in genetic diversity analysis of 40 S. lazica accessions from four locations. A total of 264 alleles were amplified with an average of 6.6 alleles per locus. The polymorphism information content (PIC) was 0.60, while the observed homozygosity (Ho) and expected heterozygosity (He) values were 0.47 and 0.66, respectively. According to cluster and structure analysis, all accessions were grouped into four different clusters according to their collection sites. The SSR markers developed in this study can be tested for other Scaligeria species due to their high transferability and can be used for genetic studies in genus Scaligeria DC.

Gul, Muhammet; Ak, M. Fatih; Guneri, Ali Fuat
Occupational Health and Safety (OHS) is a basis to reduce occupational accidents in an acceptable level, and it covers employee health, safety, and welfare in the workplaces. Hospitals as the largest employer group in healthcare industry in Turkey face major hazards categorized as chemical, biological, physical, ergonomic, and psychosocial risks. Although Turkey demonstrates rapid economic growth, OHS practices have not been fully put into practice, and necessary attention has not been paid to the health industry. For this reason, this paper aims to assess risks for health staff, contribute for planning of health services, and enhance regulations. A case study was carried out in a leading hospital in Turkey using a two-stage fuzzy multi-criteria approach, which provides more consistency in decision-making process and gives an appropriate final rank of hazard types. Fuzzy Analytic Hierarchy Process (FAHP) is used in weighing five risk parameters, which are severity, occurrence, undetectability, sensitivity to maintenance non-execution, and sensitivity to personal protective equipment (PPE) non-utilization. The fuzzy VIKOR (FVIKOR) approach is then applied for prioritization of hazard types in each department of the hospital. On conclusion of the hazard control hierarchy, measures are overtaken for the hazards, and areas open for improvement are presented.

Zabci, Cengiz; Akyüz, H. Serdar; Sançar, Taylan
The North Anatolian Fault showed a remarkable seismic activity especially between 1939 and 1999, when the westward migrating earthquake sequence created surface ruptures more than 1000 km, leaving unbroken only the Marmara segments, to the west, and the Yedisu Segment, to the east along the main strand of the fault. To understand the palaeoseismicity of the Yedisu Seismic Gap, we undertook trench investigations close to the village of Balaban SarA +/- kaya, on the western part of the Yedisu Segment. We found evidence for at least five surface faulting earthquakes, from which only two are correlated with the 18 July 1784 CE and 27 June 1583 CE historical events. Although the surface rupture of the 1784 CE was reported by other trench studies, the evidence of 1583 CE event is presented for the first time. In consideration with other historical earthquakes, affecting the region east of Erzincan, we suggest that this particular section of the North Anatolian Fault may be in a seismically quiescent period, following a cluster of earthquakes in its near history. In order to test this hypothesis, further studies are needed to increase our knowledge on the temporal and spatial seismic behaviour of the Yedisu Segment, which has potential to create an earthquake with M (w) similar to 7.2 in the near future.

Biryan, Fatih; Demirelli, Kadir; Torgut, Gulben; Pihtili, Guzin
2-Hydroxy-3-(1-naphthyloxy)propyl methacrylate (NOPMA) monomer was synthesized from reaction of 2-[(2-naphthyloxy)methyl]oxirane with methacrylic acid in the presence of pyridine. The polymerization of NOPMA was carried out by free radical polymerization method in the presence of AIBN at 60 A degrees C. The structure of monomer and polymer was characterized by H-1-NMR, C-13-NMR and FT-IR spectroscopy techniques. The glass transition temperature and average-molecular weights of poly(NOPMA) were measured using differential scanning calorimetry and gel permeation chromatography, respectively. The thermal degradation behavior of poly(NOPMA) has been investigated by FT-IR studies of the partially degraded polymer and thermogravimetry. The cold ring fractions (CRFs) were collected at two different temperatures, initially fraction-1 (CRF1) is from room temperature to 320 A degrees C, and the other fraction-2 (CRF2) is from 320 to 500 A degrees C. The volatile products of the degradation were trapped at -195 A degrees C (in liquid nitrogen). All the fractions were characterized by FT-IR, H-1 and C-13-NMR spectroscopic techniques, and the cold ring fractions (CRFs) were also characterized by GC-MS. For the degradation of polymer, the major compound between products of CRFs is alpha-naphthol. The GC-MS, FT-IR and NMR data showed that depolymerization corresponding to monomer was not prominent below 320 A degrees C in the thermal degradation of poly(NOPMA). The mode of thermal degradation containing formation of the major products was identified. The dielectric permittivity (epsilon'), the loss factor (epsilon aEuro(3)) and conductivity (sigma(ac)) were measured using a dielectric analyzer in the frequency range of 50 Hz to 20 kHz.

Objective: The study aims to investigate the phenomena in suicides and attempted suicides that have occurred in Tunceli during 2005-2015, with respect to certain characteristics. Method: The files for 435 suicides and attempted suicide incidents in total, which have been recorded in Tunceli during 2005-2015, have been examined in this paper. Results: The suicide incidents have been determined most frequently among individuals under 24 years of age. In the evaluation of the causes for suicide, unknown reasons (51.5%) have been followed by family problems (21.1%) and psychiatric disorders (18.2%). Drug intoxications, use of stabbing instruments and hanging methods have taken the top three ranks among the suicide methods. 91.3% of the incidents consisted of suicide attempts and 8.7% completed suicides. While the ratio of completed suicides has been determined to be meaningfully higher in males (7.1%), the ratio of attempted suicides has been determined to be higher in females (95.6%) (p<0.05). Furthermore, it has been determined that the suicide incidents were observed more frequently during the spring and summer seasons and more in urban zone. Conclusion: Our findings indicate that the causes of almost half of the suicide incidents in Tunceli are not known. The most important risk factors for suicide have been identified as young age, male gender, unemployment, urban life, impaired mental health and in-family problems. Further comprehensive studies are recommended as aimed to assess the suicide incidents in Tunceli and take protective measures for the risk factors.

Gül, Muhammet; Güneri, Ali Fuat; Günes, Gizem
An ideal healthcare system is considered as a system that provides the most quality service level, lower costs and unlimited access. Any delay in patient flow may result in undesired consequences and losses in healthcare facilities such as hospitals and their sub units. Project management is defined as application of techniques to project activities to meet the project requirements. It has techniques that can help healthcare facilities and units standardize care and quality, reduce costs, improve effectiveness and decrease prolonged waits. The current study is carried out in an emergency department of a university hospital to understand the patient flow of the department with respect to the Fuzzy Critical Path Method (FCPM) and Fuzzy Program Evaluation Review Technique (FPERT). The reason for incorporating fuzzy sets is stemmed from that fuzzy numbers are more effective for high uncertainty processes as in emergency departments. Activities affecting patient flow through the ED are identified and project network is drawn. 1500 patients' data about the times of each activities are obtained from the observed ED. Findings through application of FCPM and FPERT, the expected time for completion of the project, the critical path and slack times are determined.

Background: The advances in science and technology increasingly lead to the appearance of ethical issues and to the complexity of care. Therefore, it is important to define the ethics position of students studying in health departments so that high quality patient care can be achieved. Objectives: The aim of this study was to examine the ethics position of the students at Shool of Health of an University in western Turkey. Methods: The study design was descriptive and cross-sectional. The study population included 540 first, second, third, and fourth year students from the Departments of Nursing, Midwifery, and Rescue and Disaster Management in the 2013-2014 academic year. Data were collected with a Personal Identification Form and The Ethics Position Questionnaire. Obtained data were analyzed with Chi-square test, Confirmatory Factor Analysis, and Nested Analysis of Variance. Ethical considerations: Before conducting the research, approval was obtained from Ege University Clinical Research Ethics Committee in Izmir and written informed consent was taken from all the participants. Findings: There was no significant difference in the mean scores for the Ethics Position Questionnaire between the students in terms of years and fields of study. Although the mean scores for the subscale idealism did not differ between fields of study, the mean scores significantly differed between years of study. However, the mean scores for the subscale relativism did not differ in terms of years and fields of study. Discussion: Whether students are idealistic or relativistic in terms of ethical judgment will be effective in ethical decision-making skills during patient care. Therefore, we need to define the factors that influence students' ethics position in the future. Conclusion: It is suggested that the courses and practices that teach students to be aware of their ethics position to create an ethical outlook can be placed in the curriculum in health schools.

Baloglu, Ulas Baran; Demir, Yakup; Paleologu, C; McClellan, S
Smart grids are expected to replace existing electrical grids with advanced mechanisms and intelligent entities, which have excessive data processing and communication tasks. It is important for the sensitive consumer data, such as meter readings, to be secured at these intelligent entities. Novel digital communication mechanisms should be developed to protect privacy. Existing smart grid architectures do not have sufficient and efficient security functionalities for data transmission. In this paper, we propose an Identity-Based Encryption scheme, which is more promising than the classical form regarding performance and security. The proposed scheme focuses on the data structure of meter readings and optimizes this structure to achieve a better privacy preservation. This novel structure further improves the performance of the scheme by reducing communication overhead caused by public key creation and distribution operations, as evaluations demonstrated.

Aksakal, B.; Demirel, M.
Background: Syntesizing alternative bone graft materials are important in biomedical applications. Their morphology, mechanical properties and cell viability plays an important role in tissue engineering. OBJECTIVE: Bioglass (B) based bone grafts with Gelatin (G) substitution were syntesized via the sol-gel method and were compared with various Gelatin and Bioglass concentrations (wt%). METHODS: Syntesized bone grafts were characterized by Scanning Electron Microscopy (SEM) and X-ray diffraction (XRD) to show the structural and morphological changes of the fabricated B-based bone grafts. RESULTS: It was demonstrated that the concentration of pore size increased with increasing amounts of Gelatin in wt%. The biograft-B40G20 produced the highest flexture strength and hardness. Increasing the pore size caused a decrease in hardness and flexture stress of B-based biografts. CONCLUSIONS: Cell viability tests were conducted on the fabricated biografts and it was shown that the cell viability increased in fabricated B-based bone grafts.

The aim of this paper is to provide not only a hybrid theoretical methodology in multiple-attribute decision making problems but also a practical application in maritime transportation industry. The proposed hybrid approach integrates Analytic Hierarchy Process (AHP) method into VlseKriterijumska Optimizacijia I Kompromisno Resenje, (VIKOR) technique under interval type-2 fuzzy (IT2F) environment. While AHP and VIKOR provides a comprehensive framework to solve multiple-attribute decision making (MADM) problems in maritime transportation industry, the IT2F enables to deal with much uncertainty during linguistic assessment of decision-makers. The proposed approach is demonstrated with a hatch cover design selection problem since it has utmost importance in structure of bulk carrier ships to prevent water ingress and protect cargo form the external damages. Besides its robust theoretical insight, the paper has practical contribution to the naval engineers, classification societies and ship owners who have difficulty in deciding appropriate hatch cover type during construction of the ship.
