| 1 | Axial force measurement for esophageal function testing显示文摘The esophagus serves to transport food and fluid from the pharynx to the stomach. Manometry has been the 'golden standard' for the diagnosis of esophageal motility diseases for many decades. Hence, esophageal function is normally evaluated by means of manometry even though it reflects the squeeze force (force in radial direction) whereas the bolus moves along the length of esophagus in a distal direction. Force measurements in the longitudinal (axial) direction provide a more direct measure of esophageal transport function. The technique used to record axial force has developed from external force transducers over in-vivo strain gauges of various sizes to electrical impedance based measurements. The amplitude and duration of the axial force has been shown to be as reliable as manometry. Normal, as well as abnormal, manometric recordings occur with normal bolus transit, which have been documented using imaging modalities such as radiography and scintigraphy. This inconsistency using manometry has also been documented by axial force recordings. This underlines the lack of information when diagnostics are based on manometry alone. Increasing the volume of a bag mounted on a probe with combined axial force and manometry recordings showed that axial force amplitude increased by 130% in contrast to an increase of 30% using manometry. Using axial force in combination with manometry provides a more complete picture of esophageal motility, and the current paper outlines the advantages of using this method. | Flemming H Gravesen Peter Funch-Jensen Hans Gregersen Asbjφrn Mohr Drewes | 2009 | World Journal of Gastroenterology2009，15，2： | 2 |
| 2 | Shadow Education in Denmark:In the Light of the Danish History of Pedagogy and the Skepticism Toward Competition显示文摘Purpose:This article investigates the role of private supplementary tutoring in Denmark in light of the country’s pedagogical traditions in schools and leisure spheres.Design/Approach/Methods:Although tutoring activities are increasing,the phenomenon is not as prevalent in Denmark as in many other countries.In this article,we look into the history of Danish pedagogy for answers as to why this is the case.In the analytical sections of the article,we include research on parental values of child-rearing,as well as findings from a pilot study on Danish families purchasing private supplementary tutoring,the public debate about private tutoring,and contemporary youth research.Findings:With a solid emphasis on democracy and equality in Danish pedagogy,the conditions for increasing private supplementary tutoring in Denmark have been challenged.However,a current focus on global competition,formal competencies,and higher academic performance among children and young people suggests that providers of private tutoring perhaps face a brighter future—also in Denmark.Originality/Value:This article addresses a new field of qualitative research on private supplementary tutoring in Denmark and may be a platform for further reflection and empirical research. | Sidse Hφlvig Mikkelsen David Thore Gravesen | 2021 | ECNU Review of Education2021，4，3： | 2 |
