Museums are used in every discipline to collect, classify, and present information for scientific purposes. They also serve as an effective educational medium. Since the establishment of a boutique anatomy museum at Bahçeşehir University, lectures, conferences, and seminars have been organized there over the past four years on the history of human anatomy and the human body. In order to raise awareness about the need to make anatomy accessible to kindergarteners and school-aged children, rather than exclusively to undergraduate students, activities that are suited to a wide range of ages have been developed at the museum and at the anatomy laboratory. Four different sessions were conducted, including activities such as lectures using plastic models as props, shaping organs out of playdough, anatomy puzzles, watching cartoons, and examining specimens through a microscope. Healthy and pathologic anatomies were chosen to match daily themes. Among the kindergarteners and elementary school children, no grading was done, nor was any questionnaire administered; however, a survey was administered in the 10–12 age group (N = 64). According to the students' written feedback, 93.75% said they “are happy with microscope activities” while 84.37% said they “had so much fun” participating in the playdough activities. However, 18.75% criticized the activities, saying they “could have been longer.” In conclusion, it is believed that these “getting to know our bodies” activities that were hosted in the anatomy museum, including conferences, workshops, material preparation, and instructional movies, may play an important role in the development of a healthy society.  相似文献

Hasan Kahveci  Cuneyt Tayman  Fuat Laoğlu  Hüseyin Tugrul Celik  Nazan Kavas  Ömer Kılıç  Salih Aydemir 《Indian journal of clinical biochemistry : IJCB》2016,31(1):38-42

Infants with respiratory distress syndrome (RDS) may suffer from severe hypoxia, asphyxia. In this study, we aimed to evaluate serum ischemia-modified albumin (IMA) level as a diagnostic marker for hypoxia in preterm infants with RDS. Thirty-seven premature newborns with RDS were allocated as the study group and 42 healthy preterm neonates were selected as the control group. IMA was measured as absorbance unit (ABSU) in human serum with colorimetric assay method which is based on reduction in albumin cobalt binding. IMA levels were significantly higher in neonates with RDS as compared to the control group (P < 0.001). Cut-off value of IMA (ABSU) was 0.72, the sensitivity level was 91.9 %, the specificity was 78.6 %, positive predictive value was 79.1 % and negative predictive value was 91.7 % at RDS. Area under curve values was 0.93 (P < 0.001; 95 % CI, 0.88–0.98) in the receiver operating characteristic curve. We concluded that elevated blood IMA levels might be accepted as a useful marker for hypoxia in newborn with RDS.  相似文献

Drainage after total thyroidectomy or lobectomy for benign thyroidal disorders     

Colak T  Akca T  Turkmenoglu O  Canbaz H  Ustunsoy B  Kanik A  Aydin S 《Journal of Zhejiang University. Science. B》2008,9(4):319-323

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   

Collaborative project-based learning: an integrative science and technological education project     

Derya Baser  M. Yasar Ozden  Hasan Karaarslan 《Research in Science & Technological Education》2017,35(2):131-148

Background: Blending collaborative learning and project-based learning (PBL) based on Wolff (2003) design categories, students interacted in a learning environment where they developed their technology integration practices as well as their technological and collaborative skills.

Purpose: The study aims to understand how seventh grade students perceive a collaborative web-based science project in light of Wolff’s design categories. The goal of the project is to develop their technological and collaborative skills, to educate them about technology integration practices, and to provide an optimum collaborative, PBL experience.

Sample: Seventh grade students aged 12–14 (n = 15) were selected from a rural K–12 school in Turkey through purposeful sampling.

Design and methods: The current study applied proactive action research since it focused on utilizing a new way to enhance students’ technological and collaborative skills and to demonstrate technology integration into science coursework. Data were collected qualitatively through interviews, observation forms, forum archives, and website evaluation rubrics.

Results: The results found virtual spaces such as online tutorials, forums, and collaborative and communicative tools to be beneficial for collaborative PBL. The study supported Wolff’s design features for a collaborative PBL environment, applying features appropriate for a rural K–12 school setting and creating a digitally-enriched environment. As the forum could not be used as effectively as expected because of school limitations, more flexible spaces independent of time and space were needed.

Conclusions: This study’s interdisciplinary, collaborative PBL was efficient in enhancing students’ advanced technological and collaborative skills, as well as exposing them to practices for integrating technology into science. The study applied design features for a collaborative PBL environment with certain revisions.  相似文献   

Interactions and mergers of galaxies     

S M Alladin  S N Hasan 《Resonance》2007,12(3):13-26

When two galaxies approach each other, we can witness the effects of the tidal forces on a gigantic scale. Peculiar features like galactic bridges and galactic tails may form, or the two galaxies may even merge into each other and form a single system. Merger of two spiral galaxies leads to the formation of an elliptical galaxy. The interaction of gas during such galaxy encounters triggers star formation and activity of the nucleus. It is generally being accepted that galaxy interactions and mergers play a vital role in galactic evolution. S M Alladin is a retired Professor of Astronomy, Osmania University, Hyderabad. He specialized in dynamical astronomy and did research on dynamics of colliding and merging galaxies. He is also interested in interaction between religion and science. S N Hasan is an Assistant Professor of Astronomy, Osmania University, Hyderabad. His field of specialization is celestial mechanics. His research interests include the three body problem, stellar and galactic dynamics.  相似文献   

Effects of teacher professional characteristics on student achievement: an investigation in blended learning environment with standards-based curriculum     

Hasan Çakır  Barbara A. Bichelmeyer 《Interactive Learning Environments》2016,24(1):20-32

Use of different teaching materials and curriculum for the same subjects is always a confounding factor in studies investigating teacher characteristics and student achievement. The purpose of this study is to understand the effects of different teacher qualities on student achievement in high schools with a standards-based curriculum delivered over a blended learning environment. Utilizing quantitative research approach, this study investigates the effects of teacher characteristics and teaching practices in a course offered through Cisco Networking Academy, which has a standards-oriented curriculum delivered online. Participants in the study were 226 teachers and 3299 students from Networking Academies located in the USA. The findings suggest that certain teacher characteristics such as teaching experience, degree, and primary teaching field do not have effects on student achievement.  相似文献   

The innovation–economic growth nexus: Global evidence     

Iftekhar Hasan  Christopher L. Tucci 《Research Policy》2010,39(10):1264-1276

This paper extends the line of research attempting to link innovation to economic growth by addressing some unexplored questions. Using global patent data, this paper empirically investigates the importance of both the quantity and quality of innovation on economic growth, controlling for past measures of inventive inputs. Moreover, our research examines how innovation inputs can be translated into per capita growth under the various economic structures and stages of economic development. Based on a sample of 58 countries for the period 1980–2003, our empirical results indicate that countries hosting firms with higher quality patents also have higher economic growth. Furthermore, we have some evidence that those countries that increase the level of patenting also witness a concomitant increase in economic growth.  相似文献   

Faculty’s academic intellectual leadership: the intermediary relations with universities’ organizational components     

Baris Uslu  Hasan Arslan 《International Journal of Leadership in Education》2018,21(4):399-411

In line with ‘the entrepreneurial university’ discourse, managerialism and performative culture brought new expectations to faculty such as developing online programmes/courses, carrying out training for professionals, obtaining research funds, leading projects in cooperation with industry/business, collaborating with colleagues from various disciplines, participating in international networks and representing their disciplines and institutions. These new duties and the traditional roles of academics, as knowledge producer and public intellectual, constitute their intellectual leadership. Given these new circumstances, it is important to investigate the influence of universities’ organizational components to understand how university managers can support academics’ intellectual leadership. This research aims to explore intermediary relations between communication, climate and managerial practice flexibility in universities and academics’ intellectual leadership. Quantitative data were collected from 937 Turkish faculty via an online questionnaire and analysed using Path analyses. Analysis revealed that faculty, by their intellectual leadership behaviours, contribute to the development of their disciplines, institutions and society, and that communication in universities has a strong impact on faculty’s intellectual leadership by mediation of the organizational climate and managerial flexibility regarding scholarly practices. Consequently, university managers should establish functional communication systems in their institutions to generate a positive atmosphere and to maximize the efficiency of institutional practices.  相似文献
