Content Analysis of the Papers in 2015 High-Impact A-Class SSCI Journals

It was aimed in this study to reveal the general tendency of studies in the field of education by examining the papers in the high-impact A-class SSCI journals, to which qualified papers are accepted from all round the world, in terms of their dependent-independent variables, sample or study groups, research designs, data collection instruments, and data analysis techniques. The descriptive survey model was used in the research. The population of the research was all the journals surveyed in the field of educational sciences by SSCI. The journals and papers examined were selected with the purposive sampling method. 169 papers from six journals were subjected to examination within the scope of the research. Descriptive analysis and content analysis methods were used for analyzing the data. It was consequently seen that the papers used dependent variable of “student” the most which was followed by “teacher.” The most studied variable along with “student” was “academic performance.” It was found that a quite large number of dependent variables were used in the papers examined. It can be understood that studies on students among all study groups occupied the largest place, which was followed by teachers. It was seen that quantitative data analyses and experimental research studies was addressed more in the papers. Several documents and tests were mostly preferred as data collection instruments. It was noticed that the most used data analysis method was the regression analysis. Finally, some recommendations were developed in accordance with the research results.

The Advantages and Limitations of Ultrasound Elastography in Diagnosis of Thyroid Carcinoma

Thyroid nodules have high prevalence in the general population. Only minorities of thyroid nodules are malignant; nevertheless, still biopsies are performed in differential diagnosis of malignant and benign thyroid nodules. Conventional ultrasound is widely used in diagnosis and characterization of thyroid nodules. There are several suspicious ultrasound features that predict thyroid cancer, such as solid consistence, marked hypoechogenicity, taller-than-wide shape, irregular or microlobulated or spiculated margins, no peripheral hypoechoic halo, and micro- or macrocalcifications. However, none of these signs have high sensitivity or specificity nor high degree of confidence for diagnosis or exclusion of thyroid carcinoma. Ultrasound elastography, recently developed, promising, noninvasive technique that evaluates tissue stiffness, has become one of the main focuses in thyroid imaging. There are two ultrasound elastography methods: strain ultrasound elastography (also known as real-time elastography or qualitative elastography) and shear wave elastography (quantitative elastography and acoustic radiation force impulse imaging). The purpose of this chapter is to present the principles of thyroid application, advantages, and limitations of both ultrasound elastography techniques

Vitamin D Levels in Children During Winter and the Relationship Between Sunscreen and Sun Protection Behaviors

Introduction: Sunlight is the major source of vitamin D, thus, the use of sunscreens could result in vitamin D insufficiency or deficiency. Objective: We aimed to assess serum vitamin D levels in healthy children aged 0-18 years in the winter and determine the association between sunscreen use and sun protection behaviors on vitamin D status. Methods: The demographic data, clothing style, skin type, history of sunburn, history of visiting seaside towns in summer, sun protection behaviors including sunscreen use, wearing sunglasses and hats, and further detailed information about sunscreen use were recorded. Vitamin D status was assessed by measuring blood levels of 25(OH)D during winter. Results: Three hundred seventy-six children (172 boys and 204 girls) with a mean age of 128.38±56.39 months were enrolled. The mean serum level of 25(OH)D was 15.32±8.64 ng/mL. The mean values of vitamin D were associated with age, sex, traditional clothing style, having a sunburn history, and sunscreen use (p0.05). Conclusions: Sunscreen use appears to reduce vitamin D levels measured in winter. Children, especially girls and adolescents, should be exposed to sufficient sunlight to maintain normal serum vitamin D levels. Vitamin D supplementation should be given to children, especially during winter

The effects of using cartoon in teaching social sciences on attitudes of students against to social science course

3rd World Conference on Educational Sciences (WCES) -- FEB 03-07, 2011 -- Bahcesehir Univ, Istanbul, TURKEYWOS: 000466750603051In Turkey, since 2004, transition to a constructivist approach at curriculum has also led to deep-rooted changes in social sciences classes as with all courses. Change in the Social Studies Course Program made it necessary to use different types of materials in lessons by teachers. One of the materials used to make more effective and efficient of social sciences lessons is comic film that have a big place in the world of children. In this study, have been studied the effect of using comic films in teaching social sciences at the primary fifth class on attitudes of students against to social science course. The research, at the second term of 2009-2010 academic year, were made over Elementary first-grade 5 grade students. In this research, experiment and experimental design with control group were used. In the result of research, attitude of experimental group's, who are used comic films in the process of teaching procedure, towards the lesson is significantly higher than experimental group, who are not used comic films in the education process.Ankara Univ, Near E Uni

Graduate thesis studies about using material at social science education

3rd World Conference on Educational Sciences (WCES) -- FEB 03-07, 2011 -- Bahcesehir Univ, Istanbul, TURKEYWOS: 000466750603052Graduate thesis work in the field of social sciences in Turkey is increasing rapidly. Especially in 1998, the process of restructuring of faculties of education provides to an increase in both of quality and quantity of master studies in the field of social sciences as with other areas. In addition, since 2005, transition to a constructivist approach at curriculum also positively affected the diversity of graduate theses. These studies prepared by researchers have a major impact on the development of such area. At graduate studies in the field of social sciences, the researches about 'use of materials' are given wide coverage. In this study, has been examined graduate thesis about use of material in the field of social sciences by using "meta analysis model". Total 93 thesis which are composed from 87 master thesis and 6 doctoral thesis, are the subject of this study As a result of review of the literature has been reached to these studies that composes of content.

An assessment of particulate mercury and arsenic concentrations in size-fractioned total suspended particulate matter in urban areas

In this study, arsenic (As) and mercury (Hg) concentrations were determined in total suspended particulate matter (TSP) fractioned at nine different sizes (> 8, 8-6.5, 6.5-5.2, 5.2-3.5, 3.5-2.6, 2.6-1.7, 1.7-1, 1-0.43, and 10) of As were observed within the fine particle size (< 1 mu m) at all stations. The EF values of As generally decreased with increasing particle size. A significant negative correlation was observed between the size of the particles and the As concentration in the heating period at the BeAYiktaAY and Rasathane stations, which are located in residential areas. Higher Hg concentrations were found in fine particles (< 2.6 mu m) at stations near the sea, specifically during non-heating periods

Investigating of the Particulate Matter Size and the Relation of Black Smoke Near Traffic

The overall harmful effects of particulate matter on human health depend on the exposure time and the chemical and physical properties of the particulate. There is a high exposure to fine particulates near the micro environments with heavy traffic in cities. The airborne particulate matter is consisted of fine particles (PM2.5), coarse particles (PM10) and black smoke particles sourced from different sources. In past, the black smoke method was widely used to measure the airborne particles. It is known that there is a relation between the darkness of the smoke stain and elemental carbon particles. Therefore nowadays black smoke is accepted for an indicative of primary particles sourced by combustion, secondary inorganic particles and coarse particles. The persistent strong association between adverse health outcomes of air pollution sourced traffic and the black smoke has recently prompted the World Health Organization to re-evaluation of black smoke. Black smoke can be in high concentrations especially near roads depending on the number of diesel motor vehicles
