The Perception and Level of Digital Citizenship on Pre-Service Classroom Teachers

This study was aimed to determine of their perceptions and levels of digital citizenship for pre-service classroom teachers. The study was conducted with 76 senior pre-service classroom teachers at Education Faculty of B. U. The study is survey research. In this research, “The Digital Citizenship Scale” developed by Kocadağ (2012) was applied to the pre-service classroom teachers. By using open-ended questions that prepared by researchers, it was interviewed with the same students in order to making in-depth review. To determine digital citizenship levels, the frequencies, percentages, arithmetic means and standard deviations of obtained data were interpreted on the table. The data from the interviews were carried out with content analysis, which is one of the qualitative analysis methods, and had been interpreted. As a result, pre-service classroom teachers had been stated that they had no courses related with digital citizenship and its sub-dimensions during their higher education. Nevertheless, it has been found that they were correctly expressed the concept of digital citizenship. Pre-service classroom teachers have indicated that digital technologies were particularly utilized to aimed for online shopping, entering to social networking and researching of homework assignments in courses. Digital citizenship includes nine sub-dimensions that every individual should have in today’s world. The classroom teachers, that play a key role in the training of the individuals must have been trained themselves by qualified properties before the beginning of their career. It is thought that this study might be leading to further studies by training on knowledge, ability and values about digital citizenship before beginning of their service to classroom teachers

Orthodontic Treatment Need, Self-Esteem, and Oral Health-Related Quality of Life Assessment of Primary Schoolchildren: A Cross-Sectional Pilot Study

Objective:The aims of this study were (1) to determine orthodontic treatment need, self-esteem, and oral health-related quality of life (OHRQoL) of primary schoolchildren and (2) to investigate possible influences of orthodontic treatment need on self-esteem and OHRQoL.Methods:The subjects of this cross-sectional study were 219 children aged 13–14 years attending public schools in Bornova, Izmir, Turkey. None of the children were undergoing active orthodontic treatment or had previously received orthodontic treatment. Index of Orthodontic Treatment Need Dental Health Component (IOTN-DHC) was used to determine normative orthodontic treatment need, and scores of 4 and 5 were defined as treatment need. IOTN Aesthetic Component (IOTN-AC) was used for the determination of child perception as well as the orthodontist perception of treatment need, and scores of 8–10 were defined as treatment need. Rosenberg Self-Esteem Scale was applied for self-esteem level determination. OHRQoL was evaluated using Child-Oral Impact on Daily Performance (C-OIDP) questionnaire. Correlations of the obtained data were tested using Spearman rho, and groups presenting correlations were further tested using Kruskal-Wallis and chi-square test. Interoperator and intraoperator reliability of the applied tests was evaluated using weighted kappa scores.Results:Prevalence of dental normative orthodontic treatment need was 37%, with 7.3% of the children presenting no malocclusion. Of the whole population, 5.5% of the children described themselves as having definite treatment need according to IOTN-AC scores. OHRQoL was positively influenced when self-esteem was higher (p=0.01). Presence of normative orthodontic treatment need according to IOTN-DHC did not have an influence on OHRQoL (p=0.745).Conclusion:Orthodontic treatment need derived by the orthodontist might not necessarily influence OHRQoL and self-esteem of primary schoolchildren. Assessment of OHRQoL as an adjunct to conventional diagnostic tools and normative measures may be feasible for the interpretation of treatment need and priority

Management of a T-Tube Migration Into the Syrinx Cavity: a Case Report

DergiPark: 889380tmsjAims: To present a rare syringomyelia case that necessitated a revision surgery because of a T-tube migration into the syrinx cavity. Case Report: A 53-year-old female patient was presented with progressive pain in the right arm and numbness in the neck. She had undergone decompression and stabilization surgery at the T6-T9 levels four years ago. One year later, she underwent a T-tube placement operation for syringomyelia. She remained relatively stable until the latest admission. A detailed neurological examination revealed no difference compared to her previous neurological condition. Computerized Tomography and Magnetic Resonance Imaging scans demonstrated that the syrinx had expended and the T-tube had migrated into the syrinx cavity. A revision was carried out, the migrated T-tube was removed through fenestration, and a new T-tube was placed. Her condition had significantly improved at follow-up, and the syrinx had markedly regressed. Conclusion: Syringosubarachnoid shunting operations might lead to rare complications such as T-tube migration, which necessitate revision surgery. Nearly complete relief of symptoms can be achieved with successful revision surgery

Heavy Workload of Nurses and Effects of It on Sleep/Rested Levels

DergiPark: 378985tmsjAims: In this definitive cross-sectional survey study, it has been aimed to research the effect of nurse workload increase on degradation of the sleep quality and daytime sleepiness.Methods: 204 volunteer nurses who work in Trakya University Faculty of Medicine Hospital clinics have attended to this study. In the survey , TISS-28 (Therapeutic Intervention Scoring System-28) for workload, Epworth Sleepiness Scale for evaluating the sleepiness and Pittsburg Sleep Quality Index have been used. TISS28 scale data has been divided into 4 sub-groups and compared to the rates it has got from the Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index and a meaningful relationship between them has been looked for.Results: In relation to workload nearly half of the cluster (n:82) can be seen in the 2nd sub-group (p lt;0.05). We can accept that general nurse population spends a standart shift. In addition, there is a distinct statistical relationship between the degredation of sleepiness( Pittsburgh and Epworth) with the increase in the nurse workload(TISS-28). Conclusion: The increase of the nurse workload causes the degradation of the sleep status ad worsens the rested status. The degradation of the rested status and the sleep routines of the nurses, threats their health in the physical and mental way and on the other hand reduces the work effectiveness in the hospitals and causes a lot of stress and the other stress related problems in the work areas. In order to prevent this, the work condition of the nurses should be improved, their shift hours and workloads should be adjusted so as to not to disrupt their sleep statu

Adsorption challenge in the PDMS-based microfluidic systems for drug screening application

Drug screening is one of the demand areas due to close and direct dependency on human health. On the other hand, recently microfluidic systems have been increasingly used for drug development and screening purposes. However, this system has some challenges such as adsorption issue which can effect pharmacokinetic-pharmacodynamic (PK-PD) of the drugs. Thus, in this research, the issue was characterized and evaluated by UV-Vis spectrophotometry and FTIR spectroscopy devices as a model drug of cisplatin. Despite of strong relationship between logP and adsorption, and the very low value of logP in the drug candidate, the results for both apical and basal planes of the microfluidic chip confirmed the adsorption. In the UV-Vis spectrophotometry, the basal plane show 5%, and 10% higher adsorption compared to apical and control polydimethylsiloxane (PDMS)-based microfluidic. Additionally, the FTIR patterns were a good coincide with UV-Vis results

Optical coherence tomography: Is really a new biomarker for alzheimer's disease?

Introduction: Retinal ganglion cell (RGC) degeneration was histopathologically proved previously in Alzheimer's disease (AD) patients. In this study, we aimed to determine RGC degeneration in vivo using optical coherence tomography (OCT) in AD. Methods: Twenty-one mild-to-moderate AD patients and 25 cognitively healthy age-matched controls were enrolled in this case–control prospective study. All participants underwent OCT examination to assess peripapillary retinal nerve fiber layer (RNFL) thickness, macular volume, and thickness. Results: Foveal thickness and volume were significantly higher in AD patients than controls (P = 0.023 and P = 0.024, respectively). Compared to controls, peripapillary RNFL and other macular region measurements of AD patients were not statistically different (for all P > 0.05). Discussion: Increased foveal thickness and volume can be associated with the pathological changes in the early stages of degeneration These results differ from previous studies, but still confirm retinal degeneration in AD. Conclusion: With further OCT studies on large populations, OCT will be in clinical use for early diagnosis of AD

Study of bullying circumstances between 4th and 5th grade students of primary education according to various variables (Rize province example)

Bu araştırmanın amacı, İlköğretim 4. ve 5. sınıf öğrencileri arasında yaşanan zorbalığa neden olan değişkenleri çeşitli boyutlarıyla incelemektir. Araştırmanın örneklemini Rize'nin üç ilçesinde yer alan ilköğretim okullarında öğrenim görmekte olan öğrenciler arasından yansız örnekleme yöntemi ile seçilen (4.sınıf-5.sınıf) 294 ilköğretim öğrencisi oluşturmaktadır. Bu araştırma, tarama modelinde bir çalışmadır. Araştırmada, öğrencilerin zorba ve kurban olma durumlarını belirlemek için Pişkin (2002) tarafından geliştirilen “Akran Zorbalığı Anketi” kullanılmıştır. Ayrıca derinlemesine inceleme yapabilmek için 10 öğrenci ile araştırmacılar tarafından geliştirilen 3 açık uçlu soru kullanılarak mülakat yapılmıştır. Verilerin analizinde betimsel istatistikler ve Kay-kare testi kullanılmıştır. Mülakatlardan elde edilen veriler ise nitel araştırma teknikleri kullanılarak analiz edilmiştir. Elde edilen bulgulara göre öğrencilerin büyük çoğunluğunun zorbalık uyguladığı ya da kendilerinin zorba davranışlara maruz kaldığı belirlenmiştir. Öğrencilerin en sık karşılaştıkları zorbalık türünün sözel zorbalık sonrasında fiziksel zorbalık olduğu, hem okul içinde hem de okul dışında daha çok “bir erkek öğrenci” ya da “bir grup erkek öğrenci” ve kendilerinden daha büyük olanlar tarafından zorbalığa maruz kaldıkları, zorbalık olaylarıyla karşılaştıklarında özelikle bir yetişkinden yardım istedikleri veya bu duruma karşılık verdikleri ve “bedensel ve zihinsel jimnastik” ve “bilimsel farkındalık” kategorisindeki sosyal kulüplerin daha çok zorba kurban öğrenciler tarafından tercih edildiği tespit edilmiştir.The purpose of this study is to examine the variables that could cause students to make bullying between primary education 4th and 5th grade students. The study sample consists of 294 primary school students randomly selected by sampling method ( 4-5th grade) attending primary schools located in 3 towns of Rize. This study is designed as a survey method. In the study, "Peer Bullying Survey" developed by the Pişkin (2002) has been used in order to determine the status of bully and victim. In addition, 10 students has been interviewed using 3 open-ended question developed by the researchers to be able to make further examination. Kay-square test and descriptive statistics has been used to analyze the data. The data obtained from interviews has been analyzed using the qualitative research techniques. According to findings,the vast majority of students has been implemented or exposed to bullying behaviors themselves. It has been found out that the most common type of bullying faced by the students is verbal bullying after the physical bullying, they were subjected to bullying by the bigger ones both inside and outside the school by "a male student" or "a group of male student", especially when they face with incidents of bullying, they ask for help from adults or reply to this circumstance and "physical and mental gymnastics" and "scientific awareness" category social clubs are mostly preferred by the students who make bullying
