Çavdar, Ozlem; Çavdar, Ahmet; Bayraktar, Ender
In earthquake engineering, the performance-based design method is used to determine the expected performance level of structures under an earthquake effect. The level of performance is related to the damage situation that could occur in the structure after the earthquake. In performance-based structural design, it is predicted that more than one damage level can emerge under one earthquake effect. In this study, the seismic behavior of a reinforced-concrete shear-wall building that collapsed during the 2003 Bingol earthquake was investigated by nonlinear static analysis and nonlinear dynamic analysis. The selected reinforced-concrete shear-wall structure is located in Bingol, Turkey. Local code was considered for assessing a seismic performance evaluation of the selected reinforced-concrete shear-wall building. The performance goals of the reinforced-concrete shear-wall structure were evaluated by applying the pushover (incremental equivalent earthquake load) method and procedures of the code and nonlinear dynamic analysis. According to the code, the reinforced-concrete shear-wall building was not expected to satisfy life safety performance levels under a design earthquake. In this study, one collapsed building was selected in order to test the reliability and usability of performance analysis methods under different earthquakes.

Damlibag, Fatih
Nuri Seker founded Usak Sugar Factory in 1926. He targeted to produce Turkish sugar from beet. Thus, he wanted to easily ensure this need of Turkish people. He also planned to provide a regular source of income to poor peasants. He established a company and began to collect capital for the factory. Czechoslovak Skoda firm provide technology to the factory. After inauguration, Usak Sugar Factory met water supply and agricultural pest problem. Nuri Seker also had to teach newly sugar beet cultivation to peasants. In contrary to all difficulties, factory started its operations and sugar production was steadily increased. But Nuri Seker faced with financial difficulties, because experience years in sugar production increased factory's debts. As a result of these debts, government decided to liquidate the factory's company. Nationalization was practiced on 6 August 1931. During the liquidation process, rights of public partners became main argument point. Later, government decided to pay face values of public partners' shares. Eventually, links of private entrepreneurs were totally severed from Usak Sugar Factory.

Background & Study Aim: Among martial arts boxing and kickboxing are the most popular combat sports. The purpose of this study was knowledge about anaerobic power, lower-body strength characteristic and some kinetic and kinematics during loaded squat jump movement in Turkish national boxers and kickboxers. Material & Methods: Seven boxers (age: 25.5 +/- 2.57 years; boy: 174.2 +/- 4.38 cm; weight: 69.5 +/- 5.53 kg) and 6 kickboxers (age: 24.3 +/- 4.03 years; height: 176.1 +/- 9.45 cm; weight: 70.5 +/- 10.25 kg) who had ranks in competitions at Europe and World Championships. Totally 13 athletes (age: 25.0 +/- 3.24 years; height: 175.1 +/- 6.91 cm; weight: 70.0 +/- 7.70 kg), participated voluntarily in this study. Was applied and maximal anaerobic power, maximal anaerobic capacity, minimum anaerobic power and fatigue index values as both absolute and relative was obtained. One repetition maximal (1RM) values in full back squat (SQfull) movement was defined. Loaded-squat jump (SJLoaded) movement was applied by using an external load that corresponds to 40% of body weights of the participants by utilizing an isoinertial velocity transducer (T-Force dynamic measurement system) and values of mean propulsive velocity (MPV), peak velocity (PV), mean propulsive power (MPP) and peak power (PP) were obtained. Results: There are no statistically significant differences between velocity and power values during SJLoaded movement with 1RM and anaerobic power values of Turkish national boxers and kickboxers (p>0.05). Conclusion: As a result, the reason that there are no significant differences between both groups; it can be suggested that both groups consist of high-level athletes who participated in Europe and Word championships and their training systems and methods are similar to each other.

Demir, Sertac Timur
This study is a cinematic portrait not of the real, but essentially of the updated Istanbul. In the case of the strangers of cinematic Istanbul, the most strategic, useful, as well as the most difficult step for updating the city's image is to shift the axis from its centres, touristic places, familiar characters, common values and usual events to its corners, secondary places and characters, minimalist conditions, ambivalent values and current changes. For this purpose this study analyzes five films as sociological testimonies without touching upon their details but by focusing on their references: Politiki Kouzina/Bir Tutam Baharat/A Touch of Spice (Tassos Boulmetis, 2003), Koprudekiler/Men on the Bridge (Asli Ozge, 2009), Kac Para Kac/A Run for Money (Reha Erdem, 1999), Uzak/Distant (Nuri Bilge Ceylan, 2002), and 11'e 10 Kala/10 to 11 (Pelin Esmer, 2009). These films, which constitute the framework of this research, are breaking points of modern Istanbul's social and urban history and of changing form of strangers.

İncele - 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.

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.

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.

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.

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.

Finite-element (FE) model updating is a very effective procedure for determining the uncertainty parameters in a structural model and minimize differences between experimentally and analytically identified dynamic characteristics. This procedure can be practiced with manual and global/local automatic model updating procedures. Automatic model updating is very popular because of its applicability to all kinds of engineering structures to minimize differences, and its damage localization and structural health monitoring. This paper considers a historical masonry bastion to obtain its dynamic characteristics numerically with the finite-element method and experimentally with ambient vibration tests (AVTs). Sensitivity analyses for the uncertainty parameters and manual and automated model updating to minimize differences are also performed. A castle bastion located in Trabzon, Turkey is selected as an application. The FE model of structure is developed in commercial software. The first three natural frequencies are obtained between 5 and 10Hz, and AVTs are performed under natural excitation using enhanced frequency domain decomposition (EFDD) and subspace structural identification (SSI) techniques. The first three natural frequencies are obtained between 4 and 7Hz. The comparison of analytically and experimentally identified dynamic characteristics shows a close agreement between mode shapes, but 26% difference in natural frequencies. To minimize the difference, the FE model of the bastion is updated using manual and global/local automated updating, changing its material properties of Young's modulus and material density. The maximum differences are reduced from 27 to 3% with manual updating, and to 0.02% with automated model updating.
