As teaching is a nation-building profession, the career motivations of pre-service teachers are worth exploring. This study examines the career motivations of 283 Turkish pre-service teachers who have chosen teaching as a career. Accordingly, they were asked questions about deciding to teach, career perceptions, and major expectations. A profile of the participants was then developed by analyzing their responses in quantitative and qualitative ways as being descriptive, statistical, and inductive steps. It is seen that extrinsic, altruistic, and intrinsic motivations all play a role when individuals choose teaching as a career. In addition, although altruistic motives are very dominant for females, mercenary-based extrinsic motives are dominant for males. Associatively, teaching is further desired as a first profession by females. In light of the findings, we give suggestions for teacher training institutions and policy makers.

The inhibition behaviour on mild steel (MS) of Robinia pseudoacacia leaves extract (RPLE) in different concentrations in0.5 M HCl as a green corrosion inhibitor was investigated by using electrochemical techniques, surface analysis. Electrochemicalımpedance spectroscopy (EIS) measurements demonstrated that RPLE augments the char transfer resistance andthen diminishes the double layer capacitance due to the creation of a deterrent layer on the MS with increasing concentration. Polarization measurements have shown that RPLE reducing both anodic and cathodic current density values is a mixed-typeinhibitor. Also in with and without RPLE environments, the inhibition efficiencies have decreased with increasing temperaturewhile the activation energy value increases with the addition of RPLE to acidic solution. Thermodynamic parameters (suchas ΔGoads and Kads) were obtained from electrochemical measurements. Adsorption of RPLE components on MS has beendescriptived of FT-IR (Fourier Transform İnfrared Spectroscopy) and SEM (Scanning Electron Microscopy) data confirmingthe entity of a obstacle film on MS.

Foreign Direct Investment Projects of Korean Companies
Yeana Choi,Ayşe Yüce 한국유통과학회 2016 The Journal of Asian Finance, Economics and Busine Vol.3 No.1
This paper investigates announcement effects of the outward foreign direct investment (FDI) projects of the Korean multinational companies. Although the FDI is considered corporate activity that can provide various benefits beyond financial resources, the most previous research focused on macro analysis such as country-level and industry-level analysis instead of the firm-level study, which is required to decide the investment project from a management perspective. Thus, this study examines the relationship between the outward FDI activities of the Korean corporations and their financial performance to fill the gap in this area.

Autologous blood injection to the temporomandibular joint : Magnetic resonance imaging findings
Celal Candirli,Serdar Yüce,Umut Yücel Cavus,Kayihan Akin,Banu Cakir 대한구강악안면방사선학회 2012 Imaging Science in Dentistry Vol.42 No.1
Purpose : The aim of this study was to investigate the effect of the autologous blood injection (ABI) for chronic recurrent temporomandibular joint (TMJ) dislocation using magnetic resonance imaging (MRI). Materials and Methods : ABI was applied to 14 patients who had chronic recurrent TMJ dislocation. MRIs of the patients were taken and compared before and one month after the injection. Results : All of the patients had no dislocations of their TMJs on clinical examination one month after the injection. In the pre-injection, unilateral or bilateral TMJ dislocations were observed on MRIs in all patients. One month after the injection, TMJ dislocations were not observed in MRI evaluation of any patients. A significant structural change that caused by ABI was not observed. Conclusion : The procedure was easy to perform and it caused no foreign body reaction. However, it was unclear how the procedure prevented the dislocation.

Objectives: Mobile health applications that are designed without considering usability criteria can lead to cognitive overload,resulting in the rejection of these apps. To avoid this problem, the user interface of mobile health applications should be evaluatedfor cognitive load. This evaluation can contribute to the improvement of the user interface and help prevent cognitiveoverload for the user. Methods: In this study, we evaluated a mobile personal health records application using the cognitivetask analysis method, specifically the goals, operators, methods, and selection rules (GOMS) approach, along with the relatedupdated GOMS model and gesture-level model techniques. The GOMS method allowed us to determine the steps of the tasksand categorize them as physical or cognitive tasks. We then estimated the completion times of these tasks using the updatedGOMS model and gesture-level model. Results: All 10 identified tasks were split into 398 steps consisting of mental andphysical operators. The time to complete all the tasks was 5.70 minutes and 5.45 minutes according to the updated GOMSmodel and gesture-level model, respectively. Mental operators covered 73% of the total fulfillment time of the tasks accordingto the updated GOMS model and 76% according to the gesture-level model. The inter-rater reliability analysis yielded anaverage of 0.80, indicating good reliability for the evaluation method. Conclusions: The majority of the task execution timescomprised mental operators, suggesting that the cognitive load on users is high. To enhance the application's implementation,the number of mental operators should be reduced.
