Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders. 相似文献

This study explores issues of burnout and job satisfaction among special school headteachers and teachers in Turkey. The purpose of the study is to determine whether there is a difference between headteachers' and teachers' burnout and job satisfaction in terms of work status, gender and work experiences, and to analyse the factors effecting their burnout and job satisfaction. In this paper, a quantitative approach has been used: 295 subjects (33 special school headteachers and 262 special school teachers) responded to the survey. As the research instruments, the Job Satisfaction Scale and Maslach Burnout Inventory were used to measure job satisfaction and burnout levels in terms of the dimensions of emotional exhaustion, depersonalization and personal accomplishment. The study results indicated that special school headteachers felt less personal accomplishment than special school teachers. However, there were no significant differences between headteachers and teachers on two burnout dimensions, namely emotional exhaustion and depersonalization, and job satisfaction. In terms of gender, males have less emotional exhaustion and personal accomplishment but higher depersonalization than their female counterparts. Females have higher job satisfaction than their male counterparts. In relation to their work experiences, more experienced subjects have higher emotional exhaustion and depersonalization than their less experienced colleagues, and also less job satisfaction than less experienced counterparts. However, more experienced subjects who participated in the study felt higher personal accomplishment than the others. 相似文献

This study examines cross‐cultural interpretations of icons and images drawn from US academic websites. Participants from Morocco, Sri Lanka, Turkey, and the USA responded to an online questionnaire containing 18 icons and images representing online functions and information types common on US academic websites. Participants supplied meanings for icons and images and selected a preferred image to represent each of four specific online functions. From three images of professors, participants chose one with whom they would prefer to study. Data were collected at the University of New Mexico, USA; in Internet cafes in the Middle Atlas region and at Al‐Akhawayn University, Morocco; the Open University of Sri Lanka in Nawala, Nugegoda; and at Anadolu University, Turkey. A qualitative analysis examines participants' perspectives and preferences for specific representations and identifies cultural themes in relation to Hofstede's dimensions. Implications for the design of images for cross‐cultural users are discussed. L'interprétation culturelle de la signification visuelle des icônes et images utilisées dans la conception de sites Web en Amérique du Nord La présente étude porte sur les interprétations transculturelles des icônes et des images extraites de sites universitaires américains. Des participants venus du Maroc,du Sri Lanka, de Turquie et des Etats Unis, ont répondu à un questionnaire en ligne contenant 18 icônes et images représentant des fonctions en ligne et des modes d'information que l'on trouve couramment sur les sites universitaires américains. Ces participants ont attribué des significations aux icônes et images et sélectionné l'image qu'ils (elles) préféraient pour représenter chacune des quatre fonctions en ligne proposées. A partir de trois images de professeurs,les participants en ont choisi une, celle avec qui ils (elles) préféreraient étudier. Une étude quantitative examine les perspectives des participants et leurs préférences pour une représentation donnée et elle identifie les thèmes culturels par rapport aux dimensions de Hofstede. On étudie les conséquences que cela peut avoir pour la conception d'images destinées à des utilisateurs interculturels. Kulturelle Interpretationen der visuellen Bedeutung der Symbole und Bilder, die in Nordamerika Web‐Design benutzt werden Diese Studie untersucht cross‐kulturelle Interpretationen von Symbolen und Bildern, die in akademischen US‐Websites benutzt werden. Teilnehmer aus Marokko, Sri Lanka, der Türkei und den USA bearbeiteten einen Online‐Fragebogen mit 18 Ikonen und Bildern, die Online‐Funktionen und – Informationen auf akademischen US‐Websites gemeinsamen sind. Die Teilnehmer benannten angenommene Bedeutungen der Symbole und Bilder und wählten ein bevorzugtes Bild für jede der vier spezifischen Online‐Funktionen aus. Aus drei Bildern von Professoren wählten die Teilnehmer eines aus, das denjenigen zeigen sollte, mit dem sie es vorziehen würden zu studieren. Eine qualitative Analyse untersucht Perspektiven und Präferenzen der Teilnehmer für bestimmte Vertretungen und Identitäten kultureller Themen in Bezug auf die von Hofstede aufgestellten Dimensionen. Auswirkungen auf die Gestaltung von Bildern für cross‐kulturelle Nutzer werden diskutiert.

The purpose of the present study is to investigate mathematics anxiety among 220 sixth through eighth grade Turkish students in terms of mathematics achievement levels, perceived enjoyment of the mathematics teaching method, perceived enjoyment of mathematics, and perceived help with mathematics from parents. The Mathematics Anxiety Scale for Primary School Students (Bindak, 2005) was used to assess the levels of mathematics anxiety. A 3 × 2 factorial analysis of variance results showed that there was not a significant interaction effect or main effect of gender; however, there was a significant main effect of grade level. Standard multiple regression analyses show that independent variables accounted for 63% to 70% of variability in the dependent variable. The results also indicate that not only the perceived enjoyment of mathematics, but also the enjoyment of the mathematics teaching method and help with mathematics from parents had a significant effect on mathematics anxiety. 相似文献

The purpose of the study was to examine the effectiveness of the Chautauqua Professional Development Program in terms of the
mastery of basic science concepts, understanding major science processes, use of creativity skills, improvement of student
attitudes toward science, and the ability to apply science concepts and processes in new situations. Participants included
twelve teachers who agreed to participate in an experimental study where Science, Technology, and Society (STS) strategies
were utilized with two class sections where in one class the teacher determined the course structure and the form of instruction
that was typically used. Conversely, the experimental class was almost exclusively student-centered. A total of twenty-four
sections of students were in STS sections (365 students) and a similar number in control sections (359 students).The data
collected were analyzed using quantitative methods. The results were tabulated and contrasted for students enrolled in the
two sections for all the teachers. The results indicate that students in the student-centered STS sections achieved significantly
better than students in the teacher-directed STS sections in terms of understanding and use of process skills, use of creativity
skills, development of more positive attitudes; and the ability to apply science concepts in new contexts. However, there
were no significant differences noted with respect to mastery of basic science concepts. Apparently student-centered STS approaches
result in students with conceptual understandings but it is no better than the situation where teachers guide and direct inquiry
STS approaches which focus much more exclusively on specific concepts and their definitions. 相似文献

This study attempted to explore Turkish headteachers’ and teachers’ burnout and job satisfaction relating to work status, gender and years work-experiences. The purpose of this study is to find out whether there is difference between headteachers’ and teachers’ burnout and job satisfaction in terms of work status, gender and years work-experiences. In this study, quantitative approach was used. A total of 290 subjects (80 headteachers and 210 teachers) responded to the survey. As research instruments, the Job Satisfaction Scale (JSS) and the Maslach Burnout Inventory (MBI), were used to measure dimensions of headteachers’ and teachers’ burnout. The study results indicated that headteachers have more job dissatisfaction and depersonalisation than teachers. Males have less emotional exhaustion but higher depersonalisation than their female counterparts. Subjects participated in this study seemed to be different on depersonalisation and personal accomplishment dimensions on the scale in relation to their work years. More experienced subjects have higher depersonalisation and less job satisfaction than their less experienced counterparts. In contrast, more experienced subjects have higher personal accomplishment than the others. 相似文献

Science/Technology/Society (STS) as a reform effort has been active in Iowa for three decades. A program called Iowa Chautauqua has evolved over the four decades to promote K-12 STS teaching in Iowa’s 300 school districts. This is a study of how teachers have become Teacher Leaders of the reforms and lead other teachers who enroll as new teachers and schools each New Year. All were involved with Action Research projects each year while also assisting graduate student teams who serve as research associates. In this study, students were asked to identify specific teacher actions that were designed to make student learning more successful. The study examines general student views of teacher actions as well as specific examples of how students interact with the teacher and how the teachers encourage greater student/student involvement. The results show success with STS and how it defines science and affective actions of teachers in classrooms. Student views of Teacher Leaders, new Chautauqua teachers, and Control Teachers with no STS or Chautauqua experiences provide ways of recognizing successes of current reform efforts. 相似文献

ABSTRACTIn this paper, the determinants of the intention to use online learning management system (LMS) among students in one of universities in the Kyrgyz Republic were studied, using quantitative and qualitative analysis. A total of 541 responses from students, enrolled in online courses during the fall and spring semesters 2016–2017, were used to examine students attitude toward online education. In addition, interviews with six instructors were conducted. Results showed that success of students in e-courses depend on year of education and the academic major of students. Factors, defined in the scope of this work, namely, technical characteristics of LMS, ease of use, feedback options of LMS and advantages of LMS use, were also found to be significant for students in their success in online courses. In interviews with instructors, three main points were highlighted, namely, problem with students’ perception of online courses, lack of online education experience among instructors and administrative issues. 相似文献
