IntroductionBlood gas analysis (BGA) is an essential test used for years to provide vital information in critically ill patients. However, the instability of the blood gases is a problem. We aimed to evaluate time and temperature effects on blood gas stability.Materials and methodsArterial blood was collected from 20 patients into syringes. Following BGA for baseline, syringes were divided into groups to stand at 4°C and 22°C for 30, 60, 90, 120 minutes. All were tested for pH, partial pressure of carbon dioxide (pCO₂), partial pressure of oxygen (pO₂), oxygen saturation (sO₂), oxyhemoglobin (O₂Hb), sodium, potassium, glucose, lactate, oxygen tension at 50% hemoglobin saturation (p50), and bicarbonate. A subgroup analysis was performed to detect the effect of air on results during storage. Percentage deviations were calculated and compared against the preset quality specifications for allowable total error.ResultsAt 4°C, pO₂ was the least stable parameter. At 22°C, pO₂ remained stable for 120 min, pH and glucose for 90 min, lactate and pCO₂ for 60 min. Glucose and lactate were stable when chilled. Air bubbles interfered pO₂ regardless of temperatures, whereas pCO₂ increased significantly at 22°C after 30 min, and pH decreased after 90 min. Bicarbonate, sO₂, O₂Hb, sodium, and potassium were the unaffected parameters.ConclusionsCorrect BGA results are essential, and arterial sample is precious. Therefore, if immediate analysis cannot be performed, up to one hour, syringes stored at room temperature will give reliable results when care is taken to minimize air within the blood gas specimen.  相似文献   

Mobile and Information Literacy Perceptions and Skills of Library and Information Sciences and Humanities Students From Bulgaria and Turkey     

Marina Encheva  Plamena Zlatkova  Nilgün Özdamar Keskin  İlker Vatansever 《International Information and Library Review》2017,49(2):145-161

Welcome to the Global Postcards column! We are so excited to bring you news and projects from around the world. In this column, our contributors from Bulgaria and Turkey bring us a comparative study of mobile and information literacy among students at two universities in those countries. In addition to presenting perceptions of students around these literacy concepts, their research project also highlights growing trends in the use of distance education and web-based study materials. Thanks to the contributors for this issue, and please keep the submissions coming!

Distance education in the Turkish secondary education system     

Feyzi Uluğ 《Educational technology research and development : ETR & D》1994,42(4):116-119

Conclusion The OHS, although newly established, has created great interest among all the media. It is evident that this interest will continue to increase. This means that the OHS filled a very important niche in the educational structure. It is believed that most of the problems faced at the OHS will be solved in a very short time, and new ways are continually being sought. But at the moment it is necessary to remember that high quality should be maintained, instead of focusing on quantity. This motive prescribes that educational technologies should be transferred to the educational system. To accomplish this, ways should be found to increase the finances of the OHS, and governmental support should be increased to improve the technical quality. In addition, it is necessary to change the regulation of the OHS as a project of the FRTED to allow the OHS to function independently. The resulting organizational structure should be evaluated effectively. Also, it is necessary to improve the structural effectiveness of local representatives of the OHS for authorization and duties. At the same time, it is essential to use the local high schools to provide face-to-face education for distance education students. If the critics are correct, the OHS will be an original secondary-school-level distance education institute and can be a good example for other countries.  相似文献   

Powerful Actor and Hesitant Institutionalization: The State in the History of Turkish Football     

Umut Koç  Janset Özen-Aytemur 《国际体育史杂志》2016,33(16):1904-1920

We examine the validity of the assumptions of the new institutional theory about the state over the history of national football league as an institutional field in Turkey. The state is not out of the field, on the contrary, at the centre of the field, and is not an ordinary actor but the most important one although the intensity of the state’s impact changes from time to time. Sometimes, the state founds the football clubs and administrates them directly, decides who will be the champion; and sometimes, authorizes the regulative agency and gives autonomy. However, despite the state’s coercive power on the ground, the Turkish football field is still far from being fully institutionalized with its fluctuating structure.  相似文献   

Women’s Sport as a Symbol of Modernity: A Case Study in Turkey     

Gertrud Pfister  Ilknur Hacısoftaoğlu 《国际体育史杂志》2016,33(13):1470-1482

Abstract

Turkey has a distinctive position with regard to its geography and history among Muslim countries. Particular features are its secular system and far reaching modernization processes particularly with respect to the ‘emancipation’ of women. The aim of this paper is to describe and analyze sport and body politics as part of the modernization processes in Turkey and to explore in particular the multiple roles of different groups of women in the reforms initiated by the Turkish Governments. A focus will be on the intersecting influences of gender and social class. The famous archaeologist Halet Çambel will be used as an example of the ‘modern’ woman who embodied reformist ideologies. Çambel was the daughter of an elite family; she was born in Berlin where her father was an attaché at the Turkey embassy. She studied in France and participated in the Olympic Games in 1936. She and another Turkish fencer were the first women from a Muslim country to participate in the Olympic Games. Later she became the most famous archaeologist in Turkey and she stayed physically active all her life. In particular, horse riding became a favourite activity as she travelled to archaeological sites on horseback.  相似文献

A critique of John Hattie’s theory of Visible Learning     

Thomas Aastrup Rømer 《Educational Philosophy and Theory》2019,51(6):587-598

In this paper, I work out a five-stringed criticism of John Hattie’s theory of Visible Learning. First, I argue that the theory is a theory of evaluation that denies education as such. Second, I show that there are problems with the dependent variable, learning, i.e. the effect of a given intervention. Thirdly, I show that Hattie's theory belongs to the radical constructivist paradigm. Thus, the problems of constructivism, i.e. problems of normativity and the outside world, walks directly into Hattie’s concept of teaching, resulting in a double breakdown of the essence of teaching. Fourth, I argue that Hattie’s concept of feedback has a centralizing trend which ultimately has the potential to transform the country’s educational activities into a big hierarchical and data-driven organism. Finally, I show that Hattie’s reference to Karl Popper’s theory of “three worlds” is based on a highly problematic reading, where Popper’s objective world is reduced to a subset of a radical subjectivity.  相似文献
