- MakaleAçık Erişim2018Comparing Physics Textbooks in Terms of Assessment and Evaluation Tools
Takaoglu, Zeynep Baskan
Assessment and evaluation instruments provide teachers the opportunity of shaping education in the beginning, contributing to education during the process and evaluating education at the end of the process. Textbooks, on the other hand, are resources that present the aforementioned contributions to teachers at first hand. Thus, the study aims to compare the distribution of assessment and evaluation instruments in the physics textbooks being used in the academic year of 2011-2012 and 2016-2017 according to units, settlement within units and types of assessment instruments that are used. For that purpose, 9, 10, 11 and 12th grade textbooks being used in physics lessons in the academic year of 2011-2012 and 2016-2017 were examined via document analysis method. As a result of the study, it was determined that the highest number of assessment instruments in physics textbooks from two different years was encountered in the unit of force and motion. The reason for this unit having higher number of questions could be associated with higher number of mathematical operations in the unit intended for allowing students to overcome their mathematical deficiencies by practicing such questions. It was observed that the number of questions was increased especially in the books being used in the academic year of 2016-2017 and alternative assessment instruments were fewer than traditional assessment instruments. Traditional assessment instruments are still used very frequently in the textbooks, which proves the effect of traditional approaches in assessment and evaluation. Another reason for this condition is that a result-oriented evaluation is used in the university entrance exam. In the light of these results, it is suggested to make the university exam student-centered rather than making an arrangement in textbooks.

Okuroglu, Mehmet Selahattin; Solik, M; Rybansky, R
As the communication apparatus of modern system, mass media is still determinative for forming and disseminating life-styles. Since the emergence of welfare societies, presentation of life-styles in media has been considered as a tool to make use of working masses' leisure to gain profit and consent. However, from the viewpoint of critical theory, situation is more complex, relating to every aspects of modern life and shaping the ways of socialisation worldwide. The theoretical approach can be offered as a frame for utilizing pragmatics which has been used relatively rare in media studies. Based on this approach, any selected texts or the meanings of texts are not significant, unless they are connected to actions in the society. Therefore, the subject of consideration should be the arguments to be presented to individuals prior to personal actions. To transfer the focus of analyse from the texts to the arguments and to the persuasion, as a linguistic and cognitive process experienced in social level, thematic units in media texts were identified and counted. These groups of symbols or words are the units motivating individuals to choose consumption agendas or life-styles. The method of analysis in this essay had been offered in a former essay of the author, in a theoretical level. In this study, the application of method was demonstrated on magazine contents. Along with the application, theoretical approach has been modified with the help of the author's doctoral thesis, as the theory of critical media literacy. The essay's problem is the examination of magazine contents as argumentation units of instrumentalist system. Accommodating instrumental rationality within the mediated communication, similar journalistic codes can be adopted by media organizations in different countries. Therefore, in the context of globalization, celebrities page of CNN news site from USA and magazine page (Kelebek) of Hurriyet news site from Turkey were analysed. These sites could be approved for any studies because of their outstanding roles in monopolistic media groups. In addition to this, CNN has a global recognition due to the central position of USA for the system. In this case, magazine content themes, which use to construct schemas of perception and coverage at all, has been analysed as indicators of a global process persisting from the centre to the periphery. Results supported such a common process with some local differences. The method of the study can be considered a tool to describe mediatisation as a global process.

Two different methodologies were used in the empirical analysis of the study. First, the fixed effect model was estimated using the Driscoll-Kraay Standard Error Estimator. The coefficients were then estimated using the Two Stages System GMM method. The results obtained are parallel to each other. In both analyzes, per capita health expenditure has a statistically significant and positive effect on economic growth.
- MakaleYalnız künye2018An Analysis of Relationship between Military Expenditure and Economic Growth in Turkey (1960-2016)
Topal, Mehmet Hanefi
A growth number of empirical studies have investigated the relationship between military expenditures and economic growth in Turkey. However, there is no consensus on the relationship between military expenditures and economic growth in literature. The aim of this study is re-examining the relationship between military expenditures and economic growth covering the period of 1960 and 2016 within the context of cointegration and causality analysis. In addition to traditional analysis, we employed cointegration test with multi structural breaks and time-varying causality analysis. According toBayer and Hanck's (2013) standart cointegration test results the military expenditures negatively affect long-run GDP per capita. However, Maki's (2012) cointegration test with multiple breaks results show that there is no relationship between military expenditures and GDP per capita. On the other hand, time-varying causality results also indicate that the causal linkage between military expenditures and economic growth has disappeared due to economic and politic shifts in Turkey after the middle of 1970s.

Ashyralyyev, Ch; Ozturk, B.
In this paper, we generalize the well known finite difference method to compute derivatives of real valued function to approximate of second order complex derivatives w(zz) and w((zz) over bar) for complex-valued function w. Exploring different combinations of terms, we derive several approximations to compute the second order derivatives of complex-valued function. Several second order of accuracy finite differences to calculate derivatives are proposed. Error analysis in test examples is carried out by using Matlab program.

Okcu, Melih
As the world's population increases tremendously, mankind harmed the environment by applying different techniques to be able to close the deficit for food and consequently this resulted in the questioning of the effects of production techniques on food security, quality, animal welfare and their impacts on environment. Organic agriculture is developed with the help of policies that are driven by environmental and food safety. Organic livestock farming increased correlated to the increase of organic agriculture. However, getting healthy, safe and sound products from animals is only possible with the consumption of well qualified feed. Nowadays, unsatisfactory field productions, improper soil cultivation methods and more other obstacles which restrict the improvement of forage plants. In this review article, the current situation of cultivation in Turkey as well as in the world, imperfections and solution offers to those problems are stated.

Ozbek, Mehmet Ferhat
This study builds and tests the models that two types of workplace friendships (friendship with coworkers and friendship with the supervisor) may have a negative influence on employees'job insecurity and turnover intention. Further, this study assumes that the positive association between workplace friendship with a supervisor and job performance is stronger for employees having a low work ethic than for those with a high work ethic. This study also assumes that the negative relationship between friendship with a supervisor and organizational deviance is stronger for employees who have a low work ethic but not for those with a high work ethic. To test these hypotheses, 313 data samples have been collected from service sector employees. According to the results, two types of workplace friendships (friendship with coworkers and friendship with a supervisor) are negatively related to job insecurity and turnover intention. The results also show that friendship with a supervisor was positively associated with job performance for employees having a low work ethic but not for those with a high work ethic. Furthermore, the results show that friendship with a supervisor was negatively associated with organizational deviance for employees having a low work ethic but not for those with a high work ethic. Surprisingly, the friendship with a supervisor is positively associated with organizational deviance for employees having a high work ethic.

Yesilçayir, Celal
Desiderius Erasmus who is known as a prominent philosopher of renaissance period has been mentioned as a humanist or pacifist in many sources. Nevertheless, it seemed that he articulated some different thoughts beyond the ideas attributed to him. About the point in question, this work aims to discuss how to position Erasmus in ideological terms through analyzing his ideas he revealed in his works about war and peace. Within this context, it will be examined to what extent the ascription of humanist and pacifist frequently to him is coherent. Consequently, it will be tried to suggest a proposal about how we should describe him depending on the findings.

Karakurt, Birol; Sentürk, Suat Hayri; Sahingöz, Burak
Internal and external threats to Turkey lead her to have its military expenditures at a high level. The relationship between military expenditures and macroeconomic variables has been of great interest to a number of studies. However, there is no common view about the relationship between military expenditures and the inflation. In this study, the relationship between military expenditures and the inflation in Turkey is aimed to be analysed for the period 1966-2016. The length of the study period requires considering structural breaks. Therefore, according to the results of our study that benefits from a Maki cointegration test with structural breaks and Toda-Yamamoto causality test, a unidirectional positive causality between military expenditures and the inflation has been found both in the short-and the long-run.

Sari, Mahmut; Öztürk, Serkan
In this study, Ground Penetrating Radar (GPR) technique was used for the detection of i) the reasons of deformations which occur in the field ground of Gumushane University Sport Complex (GUSC), and ii) the congestion in flow pipe of Gumushane University, Engineering and Natural Sciences Faculty (GUENSF). GPR data was collected by using the RAMAC CU II device and a shielded antenna with a 500 MHz center frequency. The wave fields for GUSC were examined by 2D and 3D processing. The large-scaled hyperbolic reflections are in corresponds to the areas where the field ground has deformations. It is considered that these anomaly areas may include a gap or a padding having a large gap and suggested that these damaged areas must be full with hard materials. The large-scaled hyperbolic reflections approximately starts in one-meter depth and reaches three-meters. For GUENSF, the measurements were conducted on the route where the main flow pipe crosses. In GPR sections, hyperbolas with high amplitudes were observed in the zones where flow pipe passes. Information on slope of flow pipe was provided by examining the association of these hyperbolas with the depth, and the clogged zones were detected. It is stated that unclogging the clogged zones of the flow pipe will not fully contribute to the resolution of the problem. Therefore, it is suggested to provide necessary slope to the flow pipe by completely removing and mounting back. These results show that GPR technique is an effective tool to provide a good image and solution for the complex ground problems.

Objective: In this study, we aimed to determine the resistance mechanisms of carbapenem-resistant Enterobacteriaceae (CRE), and evaluate the prospective alternative treatment options. Methods: Between October 2014 and July 2015, rectal swabs routinely obtained from hospitalized patients were included in the study. The isolated Gram-negative enteric bacteria were identified to the species level by using standard conventional microbiological methods. Determined carbapenem resistance in enteric bacteria was confirmed by using meropenem Etest (R) (bioMerieux, Marcy l'Etoile, France), and the resistance mechanisms were investigated with MAST-ID (TM) Discs (Mast Diagnostics Ltd, Bootle, Merseyside, UK). Antibiotic susceptibilities of the CRE were determined by disk diffusion method using isepamicin, chloramphenicol, and minocycline disks (Oxoid, Basingstoke, Hampshire, UK). Results: Of the 3,323 rectal swabs sent to the laboratory during the study period, totally 84 (2.5%) CRE were isolated with one strain from each patient. Of the 84 CRE, 74 (88%) were Klebsiella pneumoniae and 10 (12%) were Escherichia coli. Among the 84 CRE, 66 (78.5%) with OXA-48, 11 (13.1%) with OXA48 + metallo-beta-lactamase (MBL), 1 (1.2%) with only MBL and 1 (1.2%) with AmpC + porin loss were detected, none of the strains were positive for KPC. In 5 (6%) strains, none of the resistance mechanisms were found. Of the 84 CRE, 80 (95.2%), 77 (91.6%) and 14 (16.6%) were found to be susceptible to isepamicin, chloramphenicol and minocycline, respectively. Conclusions: The OXA-48 type, endemic in Turkey, was also the most commonly detected carbapenemase in the study. It has been observed that isepamicin and chloramphenicol can be the potential antibiotics in the treatment of KDE-related infections.

The aim of our study was to evaluate the effects of AKI development on mortality with four different classification systems (RIFLE, AKIN, CK, KDIGO) in critically ill trauma patients followed in the intensive care unit. A retrospective review of 2034 patients in our intensive care unit was conducted between July 2010 and August 2013. A total of 198 patients with primary trauma were included in the study to evaluate the development of AKI. When the presence of AKI was investigated according to the four criteria (RIFLE, AKIN, CK, and KDIGO), the highest incidence of AKI was found according to the KDIGO classification (74.2%), followed by AKIN (72.2%), RIFLE (69.7%), and CK (59.1%). It was observed that more AKI developed according to KDIGO in patients with multiple trauma and thoracic trauma (p = 0.031, p = 0.029). Sixty-two (31%) of the 198 trauma patients monitored in the intensive care unit died; mortality was frequently found high in AKI stage 2 and 3 patients. According to the CK classification, there was a significant increase in mortality in patients with AKI on the first day (p = 0.045). AKI classifications by RIFLE, AKIN, CK, and KDIGO were independently associated with the risk of in-hospital death. In this study, the presence of AKI was found to be an independent risk factor in the development of in-hospital mortality according to all classification systems (RIFLE, AKIN, CK, and KDIGO) in critically traumatic patients followed in ICU, and the compatibility between RIFLE, AKIN, and KDIGO was the highest among the classification systems.

Objective: To evaluate the relationship between extramedian spreading of sensorial symptoms and median and ulnar nerve cross-sectional area (CSA) and to compare the ultrasonographic and electrophysiological findings in patients with carpal tunnel syndrome (CTS) with or without extramedian sensory symptoms. Design: Cross-sectional study. Materials and methods: Patients with CTS were divided into two groups as with or without extramedian symptoms and were assessed clinically, electrophysiologically and ultrasonographically by three blind investigators. In electrophysiological tests, median and ulnar nerve conduction studies were performed. Nerve cross-sectional areas were measured at hook of hamate, psiform bone, radio-ulnar joint, one-third distal part of forearm, and medial epicondyle by ultrasonography. Findings: The study was completed with 61 patients (108 hands). Extramedian symptoms were present in 31 patients (54 hands). Finger grip strength was lower, pain values evaluated with visual analogue scale were higher in patients with extramedian symptoms (p < 0.05). There was no statistically significant difference in electrophysiological and ultrasonographic parameters. Conclusion: According to our results, extramedian symptoms are not related to nerve conduction studies or nerve ultrasonography, these symptoms may be explained with central sensitization in patient with CTS.

Tekin, Sezgin; Köfteci, Sevil; Aydin, Metin Mutlu; Yildirim, Mehmet Sinan
Determination of the optimum trip schedules is an important problem for public transportation systems. It is complex task to assign optimum number of vehicles and determine the trip schedules for a public transport systems which consist of many routes. In the case of taking infrequent trip schedules, the existing passenger demand is not satisfied. Therefore waiting times are increased in the bus stops. In contrary, with more frequent intervals, unutilized capacity and higher operational costs are expected. Also, intense traffic density and environmental pollution are associated with the frequent trips. The optimum trip frequencies of the passenger demands varies during the hours of a day and is important for passenger satisfaction and operation efficiency of the system. Trip scheduling and vehicle assignment studies take attention in the current literature assisted with different optimization techniques and artificial intelligence method. In this study, only 10 different bus routes which is operated privately, were considered in the city center of Antalya and the Linear Goal Programming (LGP) was used to determine the optimum number of vehicles operated on the routes. The study results showed that the existing system performance can be preserved by reducing the frequency of specific trips and LGP is stated as an efficient algorithm for determining the optimum trip frequencies and number of vehicles in a public transportation systems.
