PRE-SERVICE BIOLOGY TEACHERS’ PERCEPTION OF THE CONCEPT OF ENVIRONMENT: A METAPHOR STUDY

The current study was conducted to reveal the pre-service biology teachers’ perceptions of environment through metaphors. A total of 71 pre-service teachers (1st year, 2nd year, 3rd year and 4th year students) participated in the current study in 2006-2017 academic year. The data of the study were obtained by asking the students to complete the sentence “environment is like… because…” five times. The collected data were analyzed according to grade level by using both qualitative and quantitative data analysis techniques. The findings of the study have revealed that the 1st year pre-service teachers produced a total of 53 valid metaphors, the second year pre-service teachers produced 39 valid metaphors, the third year pre-service teachers produced 39 valid metaphors and the fourth year pre-service teachers produced 49 valid metaphors about the concept of environment. These metaphors were analyzed in terms of their common features and by using the conceptual categories developed by Aydın (2011), they were gathered under 10 categories. The pre-service teachers’ metaphoric perceptions of the concept of environment were found to be categorically varying across the grade levels. As a result, it can be argued that metaphors can be used as effective measurement and evaluation tools in revealing pre-service biology teachers’ perceptions and mental images of the concept of environment.  Article visualizations

PROSPECTİVE TEACHERS’ OPINIONS ABOUT ANIMATIONS IN SCIENCE EDUCATION

The purpose of the current research is to determine prospective teachers’ opinions about animations. The current research employed case research design as a qualitative research method. The research group of the current research is comprised of 124 prospective primary teachers and 116 prospective science teachers. A structured form including 10 open-ended questions and a semi-structured interview form consisting of 8 questions were administered to the participants of the research. The findings of the research revealed that the opinions stated by the prospective teachers about the use of animations in science education could be gathered under the following themes: applications related to the objectives of the course, course energizers, individual differences, physical-technical capacity, student-teacher competencies, economic capacity, program capacity, learning gained with the help of others, type of music, behavioral-mental communication skills, empathy and science literacy. The data collected from the interviews showed that the prospective teachers see themselves as willing but incompetent in using animations, want to have training about the preparation of animation programs, want to use the animations they themselves develop but prefer to use the ones prepared by others and think that it is necessary to make use of animations in today’s educational environments. In light of the findings of the current research, experimental activities in the form of student seminars and courses can be suggested for prospective teachers to enhance their information, skills and competencies about animations.  Article visualizations

On-line new event detection and tracking in a multi-resource environment

Cataloged from PDF version of article.As the amount of electronically available information resources increase, the need for information also increases. Today, it is almost impossible for a person to keep track all the information resources and find new events as soon as possible. In this thesis, we present an on-line new event detection and tracking system, which automatically detects new events from multiple news resources and immediately start tracking events as they evolve. Since we implemented the on-line version of event detection approach, the novelty decision about a news story is done before processing the next one. We also present a new threshold, called support threshold, used in detection process to decrease the number of new event alarms, that are caused by informative and one-time-only news. The support threshold can be used to tune the weights of news resources. We implemented the tracking phase as an unsupervised learning process, that is, detected events are automatically tracked by training the system using the first news story of an event. Since events evolve over time, an unsupervised adaptation is used to retrain the tracking system in order to increase the tracking system performance. Adaptation is achieved by adding predicted documents to the training process. From the corpus observations, we conclude that one news story can be associated to more than one event. For this reason, the tracking system can relate a news story to more than one event. The on-line new event detection and tracking system has been tested on the Reuters news feed, available on the Internet. The Reuters news feed, that we used, comprises four independent news resources. The news stories are in Turkish.Kurt, HakanM.S

A retrospective observational study of the frequency of distomolar teeth in a population of 14.250 patients

OBJECTIVESThe supernumerary teeth that occur distally to a molar tooth described as “distomolar” teeth. Supernumerary teeth were found more often in the maxilla than in the mandible. They may erupt normally or remain impacted and appear inverted. Distomolar teeth are generally seen smaller than second or third molars and most of them are impacted The aim of this study is to determine the frequency, location, and shape of distomolar teeth in a population of urban Turkish adults.MATERIAL AND METHODSA retrospective observational study was conducted on 14.250 patients’ panoramic images, with the documentation of demographic data, the presence of distomolar teeth, their number and morphology.RESULTSThe presence of distomolars in this population was found to be 0.32%. In total, 55 distomolar teeth were detected in 45 patients. All distomolars were found in maxilla and majority of them were impacted (n=51, 92.7% of the distomolars). 19 distomolars were found bilaterally in nine cases (0.06%). In one patient, two distomolars were detected in the maxilla in which one in left and the other in the right side.CONCLUSIONSDistomolars, which described as a supernumerary tooth distal to the third molar, are rare occurring dental anomalies. Because of that clinicians should make a careful investigation of panoramic radiographs

SOMA LİNYİT AÇIK OCAĞINDA OLUŞAN DEFORMASYONLARIN İNKLİNOMETRİK YÖNTEMLE İZLENMESİ

2013 yılı Ocak-Ekim döneminde, Türkiye Kömür İşletmeleri-Ege Linyitleri İşletmesi Soma linyit açık ocağı Işıklar panosunda oluşan şev duraysızlıklarına bağlı gelişen deformasyonların miktarlarının ve yönlerinin yüzeyden ve derinden belirlenmesi amacıyla açılan iki adet inklinometre kuyusundan TKİ-ELİ tarafından ölçümler alınmıştır.

cure, erkan/0000-0001-7807-135X; Cure, Medine Cumhur/0000-0001-9253-6459; ERTURK, AYSE/0000-0001-6413-9165WOS: 000349843900013PubMed: 25657159Background: Lower limb cellulitis is an infectious disease that has serious complications unless it is treated. Objectives: in this pilot study, we evaluated whether levels of YKL-40, an acute-phase reactant, and mean platelet volume (MPV), which occurs secondary to inflammation in cellulitis, increase compared to healthy subjects. We also aimed to investigate the association between YKL-40 and MPV in the prognosis of the patients. Material and Methods: A total of 55 patients with cellulitis (23 men and 32 women) and a similar age group of 46 healthy individuals (22 men and 24 women) were included in the study. Cellulitis was diagnosed according to guideline. Serum YKL-40 levels, MPV, C-reactive protein (CRP), and other biochemical values of both groups were compared. Results: YKL-40 levels (52.2 +/- 34.5 ng/mL vs 34.6 +/- 18.0 ng/mL, P = 0.004), MPV (7.7 +/- 1.0 fL vs 6.9 +/- 0.7 fL, P < 0.001), and CRP (9.5 +/- 8.2 mg/dL vs 0.7 +/- 0.6 mg/dL, P < 0.001) were significantly higher in the patients with cellulitis than the control. the mean recovery time (RT) of the patients was 22.6 +/- 6.9 days. We found that YKL-40 (odds ratio [OR] 0.1, confidence interval [Cl] 0.028-0.191, P = 0.009) and MPV (OR 2.4, Cl 0.254-4.578, P = 0.029) have an independent association with RT. Conclusion: YKL-40 and MPV values were correlated with higher CRP in the cellulitis group than in controls. According to these results, increased YKL-40 and MPV levels might be a prognostic factor for cellulitis in patients

A retrospective evaluation of condylar morphology using panoramic radiography in a sample of Turkish population

Background: The temporomandibular joint is one of the most complex anatomic structures. It takes a great role in masticatory system and helps to make possible some functions such as speaking, chewing and swallowing. Clinicians should have sufficient anatomical knowledge to assess relationships of the hard and soft tissues, including the mandibular condyle, glenoid fossa, articular eminence of the temporal bone, the articular disc and its attachments. The aim of this study was to evaluate the frequency of different types of mandibular condyles and its distribution according to the age and gender. It was also evaluated whether the condyle types were bilaterally symmetrical or not. Materials and methods: A total of 1315 digital panoramic images which obtained from the patients suffering from the dental problems were assessed. Demographic data, condylar morphology were noted. All obtained data were analyzed by using descriptive statistics. Morphology of mandibular condyles were classified into four shapes as identified in other studies, namely: Type I - Oval shape, Type II - Diamond shape, Type III - Bird beak shape, Type IV - Crooked finger shape. Two independent examiners, who have 19 and 7 years of experience in oral and dentomaxillofacial radiology, made a consensus and evaluated all images. Results: A total of 1315 digital panoramic images were assessed. 767[58.3%] of the patients were female and 548[41.6%] were male. The age range of patients was from 18 to 84 years. Right-left condyle types were found to be symmetrical in the range of 67% of the subpopulation examined in the study. For the consensus, ‘oval’ condyle was common on both the right and left, while ‘crooked finger’ condyle was the rarest. Conclusions: The TMJ is the most important structure for all jaw functions such as speech, swallowing. In order for all these functions to continue in a healthy way, the anatomical structure should be known very well down to the finest detail. Identification of anatomical structures and their variations can play an important role in implant dentistry. Clinicians commonly prefer conventional radiologic methods to evaluate dentomaxillofacial region. Although the most of the variations are asymptomatic and require no treatment, correct identification of these findings will reduce unnecessary further diagnostic assessments and will provide more appropriate treatment plans

COVID-19 pandemic effect on female sexual function

Objectives: To determine the COVID-19 pandemic’s effect on female sexual functions among Turkish women. Material and methods: The present study was performed by using the previous study data that was conducted before the pandemic to detect female sexual function by using questionnaires. Comparison of Female Sexual Function Index (FSFI), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI) scores in women during and before the pandemic. Participants were asked to fill questionnaire forms again. Results: FSFI scores of the participants were higher before the pandemic, however, this finding was not statistically significant (21.8 vs 21.0, p = 0.27). BAI and BDI scores with high scores accompanied by anxiety and depression were found statistically significantly higher in the study (11.2 vs 13.3, p &lt; 0.01; 10.0 vs 13.7, p &lt; 0.01; respectively). BAI scores had a negative correlation with FSFI scores, however, BDI scores had not a significant correlation with FSFI scores in the present study (p &lt; 0.01, correlation coefficient = –0.302; p = 0.07; correlation coefficient = –0.183; respectively). Conclusions: Pandemic seems not to affect female sexual behavior. However, the pandemic is associated with anxiety and depression
