Sosyal medya son zamanlarda yaygın bir şekilde kullanılan önemli iletişim biçimlerinden biridir. Sosyal medya ağları olan sanal ağlar birçok nedenden ötürü sıklıkla kullanılmaktadır. Sosyal mecralar bireylere duygu ve düşüncelerini, ürün ve hizmetlerini paylaşabileceği gibi alışveriş için, oyun oynamak için girdiği bir ortamın yanında boş vakitlerin değerlendirildiği, yeni insanlar tanımak ve sohbet etmek amacıyla çeşitli nedenler ile sosyalleşme ortamı da sunmaktadır. Zamandan ve mekandan bağımsız olduğundan dolayı hızla genişleyen bir etki alanı bulunmaktadır. Kullanımlar ve doyumlar kuramını temel alarak yapılan bu çalışma elektronik anket çalışması ile yürütülmüştür. Çalışma Instagram kullanmaya yönelten amaçların neler olduğunu ve katılımcıların Instagram kullanım sürelerinin ne şekilde olduğunu tespit etmeyi amaçlamaktadır. Genç nüfusun oldukça fazla olduğu ülkemizde, özellikle 18- 28 yaş aralığındaki gençlerin Instagram'ı kullanım motiveleri çalışmanın konu eksenini oluşturmakta ve Intagram'ı kullanma biçimleri kullanımlar ve doyumlar yaklaşımının perspektifinde ortaya konulmaya çalışılmıştır.Communication between people has gained a different dimension with technological developments. Social media is one of the most important forms of communication that has been widely used recently. Virtual networks with social media networks are often used for many reasons. Social media can share feelings and thoughts, products and services to individuals, as well as shopping, play games in an environment where free time is evaluated, new people to get to know and chat for various reasons, socialization environment also offers. Since it is independent of time and space, there is a rapidly expanding domain. This study, based on the theory of usage and saturation, was carried out by an electronic survey. The study aims to determine what the aims of using Instagram are and how the duration of the participants ' use of Instagram. In our country where the young population is quite large, especially in the age range 18-28, the motivation to use Instagram is the subject axis of the study and the methods of using Intagram are tried to be introduced in the perspective of the use and satisfaction approach

THE EFFECT OF PROJECT SUPERVISION TRAINING ON TEACHERS’ VIEWS OF NATURE OF SCIENTIFIC INQUIRY

The study aimed to investigate the effect of project supervision training offered to Biology teachers on their viewpoints about the nature of scientific researches. In the study, action research design, one of the quantitative research methods, was adopted. The participants of the study were composed of 39 Biology teachers who had attended a training on project supervision. The data were collected using Assessment of Learners' Views about Scientific Iquiry (VOSI) developed by Schwarts, Lederman and Lederman (2008); and a semi-structured interview form developed by the researchers. The data were analyzed via coding and content analysis methods. The results revealed that the the project supervision training provided them with the development on five dimensions, such as scientific research is directed by questions, using different methods in scientific research,  research has many purposes, justification of scientific knowledge, and differences between scientific data and evidence. It was also found out that the training had positive effects on their professional practices

Demand for Cancer Screening Services: Results From Randomized Controlled Discrete Choice Experiments

Objectives: Low uptake of cancer screening services is a global concern. Our aim was to understand factors that influence the screening decision, including screening and treatment subsidies and a gain-frame message designed to present screening as awin–win. Methods: We analyzed preferences for mammography and Pap smear among women in Singapore by means of discretechoice experiments while randomly exposing half of respondents to a gain-framed public health message promoting thebenefits of screening. Results: Results showed that the message did not influence stated uptake, and given the levels shown, respondents were influenced more by treatment attributes, including effectiveness and out-of-pocket cost should they test positive, than by screening attributes, including the offer of a monetary incentive for screening. Respondents also underestimated the survival chances of screen-detected breast and cervical cancers. Conclusions: Combined, these findings suggest that correcting misconceptions about screen-detected cancer prognosis orproviding greater financial protection for those who test positive could be more effective and more cost-effective thans ubsidizing screening directly in increasing screening uptakes

Harmonic resonance phenomena on nonlinear SH waves

The interaction of shear horizontal (SH) waves in a two layered elastic medium and its mth harmonic component is studied. The dispersion relation is analysed to obtain the wave number-phase velocity pairs where the third and fifth harmonic resonance phenomena emerge. By employing an asymptotic perturbation method it is shown that the balance between the weak nonlinearity and dispersion yields a coupled nonlinear Schrödinger (CNLS) equation for the slowly varying amplitudes of the fundamental wave and its fifth harmonic component. The nonlinearity effects of the materials and the ratio of layers’ thicknesses on the linear instabilities of solutions and the existence of solitary waves are examined.Publisher's VersionQ4WOS:00096429890000

Quantifying Women's Stated Benefit–Risk Trade-Off Preferences for IBS Treatment Outcomes

Background: The Food and Drug Administration, currently, is exploring quantitative benefit–risk methods to support regulatory decision-making. A scientifically valid method for assessing patients' benefit–risk trade-off preferences is needed to compare risks and benefits in a common metric. Objectives: The study aims to quantify the maximum acceptable risk (MAR) of treatment-related adverse events (AEs) that women with diarrhea-predominant irritable bowel syndrome (IBS) are willing to accept in exchange for symptom relief. Methods: Research design: A stated-choice survey was used to elicit trade-off preferences among constructed treatment profiles, each defined by symptom severity and treatment-related AEs. Symptom attributes included frequency of abdominal pain and discomfort, frequency of diarrhea, and frequency of urgency. AE attributes included frequency of mild-to-moderate constipation and the risk of four possible serious AEs. Subjects: A Web-enabled survey was administered to 589 female US residents at least 18 years of age with a self-reported diagnosis of diarrhea-predominant IBS. Measures: Preference weights and MAR were estimated using mixed-logit methods. Results: Subjects were willing to accept higher risks of serious AEs in return for treatments offering better symptom control. For an improvement from the lowest to the highest of four benefit levels, subjects were willing to tolerate a 2.65% increase in impacted-bowel risk, but only a 1.34% increase in perforated-bowel risk. Conclusions: Variation in MARs across AE types is consistent with the relative seriousness of the AEs. Stated-preference methods offer a scientifically valid approach to quantifying benefit–risk trade-off preferences that can be used to inform regulatory decision-making

Determination of Effective Speech Skills of Pediatric Nurses and Affecting Factors

Aim: This descriptive and cross-sectional research aims to determine effective speech skills of pediatric nurses and their affecting factors. Materials and Methods: The study population consisted of 124 nurses working in pediatric clinics of one university hospital, two state hospitals and two private hospitals located in the Province of Erzurum, Turkey. The research data were obtained using a “Demographic Information Form” and an “Effective Speech scale (ESS)”. In the analysis of the data, percentile distributions, averages, t-test, One-Way variance analysis, Kruskal-Wallis variance analysis and Cronbach’s alpha coefficient were used. Ethical principles were adhered to when conducting the study. Results: In the study, it was found that the vast majority of nurses did not receive training to improve effective speaking skills (76.6%). It was determined that the mean ESS score was 98.40±11.08, and that the average score of the nurses who received training on effective speech skills was higher (p<0.05). Conclusion: In the study, it was determined that the nurses had moderately effective speech skills, and the average ESS score of the nurses who received training on effective speech skills was found to be higher. According to the results of the study, nurses should be supported both in their formal education and working life with activities such as domestic or foreign courses, symposiums, seminars, congresses, etc. in order to improve their effective speech skills professionally

Hypothyroidism Due to Hepatic Hemangioendothelioma: A Case Report

Although hemangioendothelioma (HHE) is a commonly encountered hepatic tumor during infancy, HHE−related hypothyroidism is rare. We present a patient who developed HHE−related hypothyroidism during the neonatal period and showed marked improvement in hypothyroidism by regression of HHE. A 28−day−old boy with TSH level of 77 mIU/mL on neonatal screening and diagnosed as congenital hypothyroidism was started on L−thyroxine (L−T4) (11 μg/kg/day) therapy on the 21th day of life. On physical examination, the liver was palpable 5 cm below the right costal margin, and the thyroid gland was nonpalpable. Thyroid ultrasonography was normal. Although L−T4 dose was increased to 15 μg/kg/day, TSH was not suppressed and free T3 level remained low. HHE in both lobes of the liver was detected by abdominal ultrasonography and magnetic resonance imaging. Treatment was started with prednisolone 2 mg/kg/day and alpha−interferon 3 million U/m2/3 times per week. Thyroid dysfunction was thought to be due to type 3 iodothyronine deiodinase activity expressed by HHE. L−T4 therapy was changed to Bitiron® tablet, which includes both T4 and T3, and euthyroidism was attained within 1 month. Thyroid hormone requirement was reduced and treatment was discontinued after regression of the HHE. At the most recent visit, the patient was 21 months old and off treatment. His growth and neurological development were normal for age and he was euthyroid. HHE should be considered in cases with severe hypothyroidism resistant to high−dose thyroid hormone replacement. The treatment of HHE in combination with T4 and T3 therapy results in euthyroidism

Evaluation of intraocular pressure and retinal nerve fiber layer thickness in patients with Helicobacter pylori

Objectives: High prevalence of Helicobacter pylori (HP) in the glaucoma patients was shown in recent studies. In our prospective study we aimed to compare the intraocular pressure (IOP) and the retinal nerve fiber layer thickness (RNFLT) in patients with HP positive and negative. Methods: In 91 patients with gastritis HP was investigated by urea breath test (UBT) and biopsy sample culture Following the full ophthalmologic examination the patients’ IOP was measured by Goldmann applanation tonometry and RNFLT was measured by spectral optic coherence tomography. The patients' demographic and clinical characteristics were compared with the χ² test for categorical variables and with the Mann Whitney U test for continuous variables. Results: Of the 90 patients who meet the including criteria, HP was detected in 74 patients (27 male, 47 female) positive, and in 16 patients (7 male, 9 female) negative. Median (minimum-maximum) age values were 46 (18-79) in HP positive group and 51 (18-67) in HP negative group. One hundred forty seven eyes in 74 HP positive patients and 31 eyes in 16 HP negative patients included in the study. Median IOP values were determined 14 (7-21) mmHg in HP positive group and 14 (8-18) mmHg in HP negative group. The measurements of RNFLT in superior, temporal, inferior and nasal quadrants found to be respectively 122(98-165), 68(50-101), 135(93-188), 79(51-120) micron in HP positive group and 120(94-161), 67(43-104), 129(94-166), 76(50-97) micron in HP negative group. No statistically significant difference was found when compared IOP and RNFLT measurements between the two groups (p<0.05). Conclusion: In this study found that the IOP and RNFLT measurements of HP positive group was not show statistically significant difference compared with HP negative group. In a large case series, randomized, case-controlled, histologic and serologic studies should be done to show the relationship between HP and glaucoma

An appeal to the global health community for a tripartite innovation: an ‘‘Essential Diagnostics List,’’ ‘‘Health in All Policies,’’ and ‘‘See-Through 21st Century Science and Ethics"

Diagnostics spanning a wide range of new biotechnologies, including proteomics, metabolomics, and nanotechnology, are emerging as companion tests to innovative medicines. In this Opinion, we present the rationale for promulgating an ‘‘Essential Diagnostics List.’’ Additionally, we explain the ways in which adopting a vision for ‘‘Health in All Policies’’ could link essential diagnostics with robust and timely societal outcomes such as sustainable development, human rights, gender parity, and alleviation of poverty. We do so in three ways. First, we propose the need for a new, ‘‘see through’’ taxonomy for knowledge-based innovation as we transition from the material industries (e.g., textiles, plastic, cement, glass) dominant in the 20th century to the anticipated knowledge industry of the 21st century. If knowledge is the currency of the present century, then it is sensible to adopt an approach that thoroughly examines scientific knowledge, starting with the production aims, methods, quality, distribution, access, and the ends it purports to serve. Second, we explain that this knowledge trajectory focus on innovation is crucial and applicable across all sectors, including public, private, or public–private partnerships, as it underscores the fact that scientific knowledge is a co-product of technology, human values, and social systems. By making the value systems embedded in scientific design and knowledge co-production transparent, we all stand to benefit from sustainable and transparent science. Third, we appeal to the global health community to consider the necessary qualities of good governance for 21st century organizations that will embark on developing essential diagnostics. These have importance not only for science and knowledge based innovation, but also for the ways in which we can build open, healthy, and peaceful civil societies today and for future generations
