The Impact of Internet and Social Media on Kids’ and Parents’ Game Habits

Internet, already a part of our lives far surpassing its limits as a means of communication, seems to have shaped most fields in human life and changed most of our daily habits and as a consequence the digital natives are observed to be completely living in Internet culture. One of the reflections of this culture and arenas in the Internet, social media has substantial impacts on gaming habits of digital natives. Up to the period in which Internet has interfered in man’s life, the games played by parents were passed from older generations to the new ones as a tradition, so generations used to play the same games; when the children of a previous era became parents they described the games they used to play to their kids thus paving the way to the sustainability of this game tradition. While different generations used to play the same games, today with the dissemination of Internet and social media caused a change of format in the traditionally played games and street games started to give their places to those played on the computers. Therefore, children started to play games on the Internet, an endless space whether negative or positive. The fact that parents are alienated from this arena, enabled the children to play violent games without any boundaries and to take place in social media arenas that could have negative impact on children’s worldly and spiritual well-being. The study is highly important in the sense that it clarifies the extent to which Internet and social media, which is actually the agent of change in children’s gaming habits, environments changed parents’ gaming habits among themselves and with their children. Surveys are conducted to the parents of primary school students as a field work to identify the changes originating from Internet and social media. According to research results, social media and Internet are found to be altering gaming habits of parents with their children. It is identified that parents keep themselves away from online environments in which their kids take place thus possibly breaking off the communication relationships between kids and parents

Mentor and Peer Feed-Back on Micro-Teaching: As a Tool for Enhancing of Pre-Service Teachers' Teaching Practices

The purpose of this study was to investigate how feedbacks left from two different sources (mentors and peers) during microteaching sessions effecting preservice teachers' teaching skills and views on science teaching. Sampling process is twofold in the study. As part of qualitative research, among other counterparts, case study method was chosen and respectively, constructed six working groups in which there were six preservice teachers, totally from thirty six preservice teachers enrolled in the third grade of Elementary Education Department by random assignment. Subsequently, one preservice teacher from all groups was appointed as the moderator of those groups (totally six moderators). Rest of them taking part remained as audience in all groups. At the beginning of the instructional process, all participants were asked to watch some videos by which someone already recorded. After watching these videos, they were also given a chance to discuss their ideas and impressions regarding microteaching in the classroom atmosphere. Both academic staff as mentors and participants as preservice teachers took role in the process of determining which teaching skills would be taken into consideration as part of microteaching sessions. Each group were gathered at regular intervals throughout twelve weeks together with their mentor who guided them and performed their microteaching. Data was collected using reflective diaries by which researchers constructed for both preservice teachers playing role as teacher of the group and preservice teachers playing role as audience during these microteaching sessions. Semi structured interviews were also carried out with only preservice teachers playing role as teachers of the groups. Findings from these reflective diaries and semi structured interviews were analysed by descriptive statistics and content analysis method. With regard to these findings, explanatory themes and subthemes were categorized and supported by direct citations. The results reveal that preservice teachers playing role as the teachers of the each group consider "content knowledge" as the most important aspect among other teaching skills. Furthermore, preservice teachers also point out that the more they get feedback on any teaching skill, the more they get motivated to develop it

Does Hypothyroidism Affect Gastrointestinal Motility?

Background. Gastrointestinal motility and serum thyroid hormone levels are closely related. Our aim was to analyze whether there is a disorder in esophagogastric motor functions as a result of hypothyroidism. Materials and Methods. The study group included 30 females (mean age ± SE 45.17 ± 2.07 years) with primary hypothyroidism and 10 healthy females (mean age ± SE 39.40 ± 3.95 years). All cases underwent esophagogastric endoscopy and scintigraphy. For esophageal scintigraphy, dynamic imaging of esophagus motility protocol, and for gastric emptying scintigraphy, anterior static gastric images were acquired. Results. The mean esophageal transit time (52.56 ± 4.07 sec for patients; 24.30 ± 5.88 sec for controls; P = .02) and gastric emptying time (49.06 ± 4.29 min for the hypothyroid group; 30.4 ± 4.74 min for the control group; P = .01) were markedly increased in cases of hypothyroidism. Conclusion. Hypothyroidism prominently reduces esophageal and gastric motor activity and can cause gastrointestinal dysfunction

Predictors of mortality in patients with prosthetic valve infective endocarditis: A nation-wide multicenter study

Background: Our aim was to investigate the clinical and prognostic features of the patients with prosthetic valve endocarditis (PVE) in a multicenter nation-wide study.Methods: The present nation-wide study consisted of 75 consecutive patients with PVE treatedat 13 major hospitals in Turkey from 2005 to 2012.Results: The patients who died during follow-up were significantly older than the survivors and had higher C-reactive protein (CRP), creatinine, poor NYHA functional class and large vegetations. High creatinine level (odds ratio [OR] 2.6, 95% confidence interval [CI] 1.14–6.13), poor functional status (OR 24.5; 95% CI 3.1–196.5) and high CRP (OR 1.02; 95% CI1.00–1.03) measured on admission were independent risk associates for in-hospital mortality.Conclusions: High creatinine level, poor functional status and high CRP measured on admission were independent risk associates for in-hospital mortality, whereas a NYHA class ofIII/IV and high CRP reflected independent risk for stroke/mortality end point

Calculation of the mechanical properties of FeB layer's by finite element method

Surface treatments of engineering materials are important for serviceable engineering components. One of the thermo-chemical surface treatments of steel based materials is the boriding process. In this study, low alloy steel substrates were borided by pack boriding process at 900 °C. Experimental indentation tests were conducted on Dynamic Ultra-micro Hardness test machine, under applied peak loads of 800 mN, 1000 mN, 1200 mN and 1400 mN. To get the mechanical properties of FeB layers, the resulting load-unload test data of the samples obtained from the experimental indentation tests were analyzed and curve-fitted in Kick's and Meyer's law for the loading and the unloading part of the load-unload curve respectively. Then, a set of analytical functions that take the pile-up and sink-in effects into account during instrumented sharp indentation were solved using numerical methods. These analytical functions were defined within an identified representative plastic strain, εr, for the Vickers indenter geometry as a strain level that allows for the description of the indentation loading response independent of strain hardening exponent, n. The mechanical characterization of samples, finite element modeling was applied to simulate the mechanical response of FeB layer on low alloy steel substrate by using ABAQUS software package program. © Association for Scientific Research
