Implications of Learning Theories for Effective Technology Integration and Pre-service Teacher Training: A Critical Literature Review
Mustafa KO
Journal of Turkish Science Education , 2005,
Abstract: This review will explore the influences of technology integration into pre-service teacher education programs from the constructivist and behaviorist perspectives for the ultimate aim of improving student learning and pre-service teacher training. A wide range of research is cited, including research articles, books, comparison studies, case studies, government records, dissertations and web sites. The study concludes that technology integration representing learning from technology (behaviorist perspective) is not the most effective way to improve learning although it helps learners to perform the lower level subskills automatically. On the other hand, constructivist-learning environments representing learning with technology, which encourages learners to actively process and organize information by making internal cognitive connections, can well provide the theoretical framework for the effective technology integration.

International Journal of Human Sciences , 2010,
Abstract: The aim of this study is to evaluate instructional computer laboratories according to the physical ergonomic criteria. A case study design with survey methodology was employed and data were collected through observation. Three computer labs were selected from various departments at the Suleyman Demirel University in Isparta, Turkey. The observation form, which was generated after reviewing the related literature, was used to gather data about computer labs’ physical characteristics, relative humidity and temperature levels, noise levels, desks and chairs, and technical features. The results reveals that the physical features of computer labs, monitor features, relative humidity and temperature levels are in agreement with the ergonomic criteria. However, desks and chairs, keyboard features, and noise levels fail to comply with the criteria, which can cause health problems and decrease the quality of students’ studies. Some suggestions are offered to improve computer labs’ study environments.Extended : There have been significant changes and innovations in every aspects of human lives. Education is one of the areas that may have been greatly influenced by these changes. Information and communication technologies changed the nature of teaching and learning. They facilitate active student participation, fast and durable learning, visualization, enjoyable learning, saving of time and so on. Therefore, educational institutions establish computer labs to support instructional activities. Although computers provide a number of opportunities, their uses in inappropriate and uncomfortable working conditions have recently caused some serious health problems. Common medical concerns include but not limited to eye strain, vision problems, headaches, pain in the lumbar region of the back, and strain on the ligaments in the back of the hand and wrist. Such problems have become the topic of many research studies and several ergonomic criteria have been established by educational and medical academics. Educational institutions should pay attention to these criteria while setting up computer labs so that students can efficiently benefit from computers. The purpose of this study is to evaluate instructional computer labs’ physical characteristics according to ergonomic criteria suggested in the related literature.This study was designed as a case study with survey methodology. Case studies allow researchers to deeply examine an object, subject, event and related variables by means of collecting detailed information. Three computer labs were chosen from various departments
“Acrania”: Two Case Reports With Prenatal Ultrasound Results
Mustafa Ko,G?khan Akba?
Erciyes Medical Journal , 2008,
Abstract: Acrania is a rare congenital anomaly and characterized by partial or complete absence of the calvarium with abnormal brain tissue development. The pathogenesis of acrania is unknown and differential diagnosis should be searched to rule out other similer conditions to anencephaly and acalvaria. Diagnosis of cranial bone defects can be established by ultrasonography in the first trimester of pregnancy. We report two cases, diagnosed prenatally by ultrasonography, one with isolated acrania and the other one associated with meningocele.

Mustafa Ko,Hasan Baki Alt?nsoy
Erciyes Medical Journal , 2007,
Abstract: Hydatid cyst is a parasitic infestation with rare presentation in the cerebrum. Hydatid cyst disease is rare in the cerebrum and lebions are usaally single, accounting for only 1,6-5,2 % of all hydatid cysts. The differential diagnosis of cerebral cystic echinococcosis includes abscess, cystic tumor, arachnoid cyst, and porencephalic cyst. In this report, we aim to present MRI findings of a gigantic intracranial hydatid cyst mass which ihas not been previously described in this size before.

International Journal of Human Sciences , 2011,
Abstract: This study is aimed to investigate the conceptions of employer and master instructors on students from vocational education center. Workgroup of the study comprises totally 318 people who work as employers and master instructors in the field of production and serving in Kayseri and Sakarya cities, in 2011. Data is collected via personal information form and determining conceptions of employer and master instructors on students in vocational education survey, which was developed by researchers for the purpose of determining the conceptions of employers and master instructors on students from vocational education center. Descriptive analysis such as frequency and percent was used in data analysis. Besides, Kay- square technique was used according to positions of employers and master instructors, by the aim of determining the conceptions of employers and master instructors on students from vocational education. According to research, significant differences between conceptions of employers and master instructors about students from vocational education center were found. Results of the study were discussed in related literature and submitted suggestions for future studies.
Thymic Hyperplasia Presenting as a Neck Mass in Graves Disease
Serkan Yener,Mustafa Se?il,Mehmetali Ko?dor,?zhan ?zdo?an
Turkish Journal of Endocrinology and Metabolism , 2009,
Abstract: We describe a female patient who presented with Graves disease and a neck mass. Radiological characteristics of the mass suggested thymic hyperplasia. She was treated with methimazole, and because the mass did not regress after six months of therapy, the patient had total thyroidectomy and thymectomy. Pathological examination was consistent with chronic lymphocytic thyroiditis and thymic hyperplasia. Microscopic changes in the thymus can be detected in one third of patients with Graves disease, but massive enlargement is rare. It has been reported that regression occurs in most patients after a euthyroid state has been achieved; however, in some patients, thymectomy may be indicated. Turk Jem 2009; 13: 11-2

Anadolu Kardiyoloji Dergisi , 2010,
Abstract: Objective: We aimed to investigate the relation of brachial artery intima-media thickness (IMT) with endothelial function and left ventricular mass (LVM). Methods: Fifty four stage I-II hypertensive patients according to JNC VII who were not taking any medication and 27 age and sex-matched healthy controls were included to this cross-sectional observational study. IMT was measured by the same radiologist who was unaware of the patient’s clinical status by using high resolution ultrasound machine. Endothelial function was evaluated by flow mediated dilation (endothelium-dependent vasodilatation, FMD). LVM was calculated by using Devereux method. LVM index (LVMI) was obtained by dividing LVM to body surface area. Mann-Whitney U test was used to compare continuous variables, qualitative variables were compared by Chi-square test and the relations of parameters were evaluated by multiple linear regression analysis. Results: Both groups (hypertensive and control) were similar with respect to age, sex, left ventricular ejection fraction. IMT was significantly higher in hypertensive group (0.43±0.09 vs 0.33±0.06 mm; p<0.001). FMD values were also significantly different between hypertensive and control groups (4±4% vs 13±12%; p<0.001). LVMI was significantly different between hypertensive and control groups LVMI (124 ± 5 vs 99±6 gr/m2, p=0.002). The correlation between IMT and FMD (r=0.260; p=0.026) and IMT and LVMI (r =0.348; p=0.004) were statistically significant. A correlation was found between IMT and LVMI independently of other variables (beta=105; p=0.004) when LVMI was accepted as dependent variable in multivariate linear regression analysis (R2=0.570, p<0.001). According to this finding, the 105 units increase in LVMI occurs when IMT increases by 1 mm. Conclusion: Brachial artery IMT is related to endothelial function and LVM. According to these data, any negative changes of the IMT may reflect the similar negative changes in other parameters.

Abstract: The therapeutic use of autologous platelet-rich fibrin constitutes a relatively new biotechnology that has been a breakthrough in the stimulation and acceleration of soft-tissue and bone healing. The efficiency of this process lies in the local and continuous delivery of a wide range of growth factors and proteins, mimicking the needs of the physiological wound healing and reparative tissue processes. Platelet-rich fibrin (PRF) belongs to a new generation of platelet concentrates, with simplified processing and without biochemical blood handling. This easy protocol allows the production of leukocyte and platelet-rich fibrin clots starting from autologous blood samples. PRF is used especially in clinical Periodontal and Oral and Maxillofacial Surgery applications. The significance of the PRF is gradually increasing Keywords: Platelet, Autogenous Fibrine, Growth hormone.
