Günderci, Azad; Karatay, Gulnaz; Gökçe, Seher; Güler, Burcu
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.

Pekel, Engin; Gul, Muhammet; Celik, Erkan; Drobne, S.; Zerovnik, J.; Zadnik Stirn, L.; Kljajic Borstar, M.
An Emergency Department (ED) plays a crucial role in the health system by providing acute care for patients who attend hospital without prior appointment. An accurate forecasting of patient visits in EDs contributes to health care decision makers to better allocate ED human resources and medical equipment. In this paper, a hybrid genetic algorithm–artificial neural network (GA–ANN) approach is developed. The forecasting performance of the hybrid approach is obtained using the real-world data set collected from a public hospital in Istanbul, Turkey. The hybrid GA–ANN model is shown to perform well in terms of forecasting accuracy. In order to contribute to the current knowledge, this paper is a novel attempt of applying GA-ANN to model ED patient arrivals, and the results can be used to aid in strategic decision-making on ED resource planning in response to predictable arrival variations.

Soner, Omer; Celik, Erkan; Akyuz, Emre
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.

Ince, Muharrem; Ince, Olcay Kaplan
The aim of the present research was to apply the Box-Behnken experimental design and response surface methodology for modeling of copper (Cu2+) ions from an industrial wastewater and leachate pretreated astragalus herbal plant. A three factor, three level Box-Behnken experimental design combined with response surface modeling (RSM) and quadratic programming (QP) was employed for maximizing Cu(ID removal from aqueous solution based on 17 different experimental data obtained in a batch experimental study. Three independent variables (pH ranging from 2.0 to 8.0, contact time from 10 to 180 minutes, and adsorbent amount from 0.1 to 1 g) were studied. The significance of the independent variables and their interactions were tested by means of the analysis of variance (ANOVA) with 95% confidence limits. The standardized effects of the independent variables and their interactions on the dependent variable were also investigated by preparing a Pareto chart. The optimum values of the selected variables were obtained by solving the quadratic regression model as well as by analyzing the response surface contour plots. Using the experimental conditions of pH = 5.0, contact time = 92.5 minutes, adsorbent dosage = 0.25 g, the recovery efficiency of Cu(II) was found to be 100%. Copper-free and copperloaded astragalus was analyzed using fourier transform infrared spectrometry (FTIR) which evidenced the functional groups involved in copper uptake. Adsorption equilibrium for copper was described by using the Freundlich and Langmiur adsorption isotherms. This adsorbent was applied to different industrial wastewater and leachate samples for copper removal.

Hybrid renewable energy systems considered as candidate solutions for environmental problems. Solar energy and wind energy are important components of these systems, but both of them cause fluctuations in the grid. Batteries of Electric Vehicles (EVs) can be connected to the grid to create an ancillary resource. These systems known as Vehicle to Grid (V2G) and they could be the most suitable solution to the fluctuation problems of renewable resources. In this paper, economic analysis of V2G is investigated from various perspectives. The findings of this study indicate that battery aging costs of a V2G system can be minimized with an intelligent energy management system, and these systems are both economically and environmentally better alternatives to fossil-fuelled generators.

Can, Umit; Alatas, Bilal
The classical optimization algorithms are not efficient in solving complex search and optimization problems. Thus, some heuristic optimization algorithms have been proposed. In this paper, exploration of association rules within numerical databases with Gravitational Search Algorithm (GSA) has been firstly performed. GSA has been designed as search method for quantitative association rules from the databases which can be regarded as search space. Furthermore, determining the minimum values of confidence and support for every database which is a hard job has been eliminated by GSA. Apart from this, the fitness function used for GSA is very flexible. According to the interested problem, some parameters can be removed from or added to the fitness function. The range values of the attributes have been automatically adjusted during the time of mining of the rules. That is why there is not any requirements for the pre-processing of the data. Attributes interaction problem has also been eliminated with the designed GSA. GSA has been tested with four real databases and promising results have been obtained. GSA seems an effective search method for complex numerical sequential patterns mining, numerical classification rules mining, and clustering rules mining tasks of data mining.
