Application of digital image correlation to full-field measurement of shrinkage strain of dental composites

Objectives: Polymerization shrinkage of dental composites remains a major concern in restorative dentistry because it can lead to micro-cracking of the tooth and debonding at the tooth-restoration interface. The aim of this study was to measure the full-field polymerization shrinkage of dental composites using the optical digital image correlation (DIC) method and to evaluate how the measurement is influenced by the factors in experiment setup and image analysis. Methods: Four commercial dental composites, Premise Dentine, Z100, Z250 and Tetric EvoCeram, were tested. Composite was first placed into a slot mould to form a bar specimen with rectangular-section of 4 mm mm, followed by the surface painting to create irregular speckles. Curing was then applied at one end of the specimen while the other part were covered against curing light for simulating the clinical curing condition of composite in dental cavity. The painted surface was recorded by a charge-coupled device (CCD) camera before and after curing. Subsequently, the volumetric shrinkage of the specimen was calculated with specialist DIC software based on image cross correlation. In addition, a few factors that may influence the measuring accuracy, including the subset window size, speckle size, illumination light and specimen length, were also evaluated. Results: The volumetric shrinkage of the specimen generally decreases with increasing distance from the irradiated surface with a conspicuous exception being the composite Premise Dentine as its maximum shrinkage occurred at a subsurface distance of about 1 mm instead of the irradiated surface. Z100 had the greatest maximum shrinkage strain, followed by Z250, Tetric EvoCeram and then Premise Dentine. Larger subset window size made the shrinkage strain contour smoother. But the cost was that some details in the heterogeneity of the material were lost. Very small subset window size resulted in a lot of noise in the data, making it difficult to discern the general pattern in the strain distribution. Speckle size did not seem to have obvious effect on the volumetric shrinkage strain along specimen length; however, larger speckles resulted in higher level of noise or heterogeneity in the shrinkage distribution. Compared with bright illumination, dimmer lighting produced larger standard deviations in the measured shrinkage, indicating a higher level of noise. The longer the specimen, the greater was the rate of reduction with distance from the irradiated surface, especially for the longitudinal strain. Significance: The image correlation method is capable of producing full-field polymerization shrinkage of dental composites. The accuracy of the measurements relies on selection of optimal parameters in experimental setup and DIC analysis.     

Comprehensive Guidance and Counselling Programmes in the Primary Schools of Hong Kong: Teachers' Perceptions and Involvement

This article describes teachers' and Life Education Coordinators' perceptions of, and involvement in, the guidance and counselling activities in primary schools in Hong Kong. Respondents who completed a survey questionnaire comprised 367 class teachers and 66 Life Education Coordinators from 82 primary schools. The results indicated that guidance and counselling activities (including guidance curriculum, individual planning, responsive services, and system support) were being implemented in their schools to some reasonable extent. Some differences between teachers and Life Education Coordinators in terms of their involvement and perceptions are discussed. The survey identified a major weakness in the present guidance system in that many teachers who are involved in, and responsible for, implementing a guidance curriculum do not have any training in guidance work. Implications are discussed.     

Developing a Career Development Self-Efficacy Instrument for Chinese Adolescents in Hong Kong

A 24-item measure, the Career Development Self-Efficacy Inventory (CD-SEI), was developed to assess career development self-efficacy among adolescents in Hong Kong. The CD-SEI covered six domains representing competencies needed by high school students transiting from school to work in Hong Kong. The confirmatory factor analyses of the responses from 6776 Grades 10–13 students showed that the six primary factors with one higher order factor model was the best fit to the data, though the one general factor model yielded an adequate fit. Reliability analyses showed that the total scale and subscales were internally consistent. The data suggested that Hong Kong adolescents had some, but not strong confidence in their career development. Students with plans to study at a university had more confidence in their career development than those who did not have such plans. This is the first study to develop and validate a career development self-efficacy measure for Chinese adolescents. Issues related to comprehensive guidance programming and assessment instrument development from a cross-cultural perspective were discussed.

Résumé. Construction d’un instrument de mesure de l’auto-efficacité du développement vocationnel pour adolescents chinois de Hong Kong. On a construit une échelle de 24 items, appelée Career Development Self-Efficacy Inventory (CD-SEI) (Inventaire de l’Auto-efficacité de Développement Vocationnel (IAE-DV)) pour évaluer l’auto-efficacité du développement vocationnel chez des adolescents chinois de Hong Kong. La CD-SEI couvre six domaines, qui représentent les compétences dont ont besoin les étudiants des hautes écoles qui sortent de l’école pour entrer sur le marché du travail à Hong Kong. Les analyses factorielles confirmatoires des réponses de 6776 étudiants des niveaux 10–13 montrent que c’est un modèle à six facteurs primaires avec un facteur de premier ordre qui s’ajuste le mieux aux données, bien qu’un modèle à un seul facteur général procure un ajustement satisfaisant. Les analyses de fidélité attestent de la consistance interne de l’échelle totale et des sous-échelles. Les données suggèrent que les adolescents de Hong Kong n’ont qu’une confiance relative dans leurs possibilités de développement vocationnel. Les étudiants qui ont décidé d’étudier à l’université ont d’avantage confiance en leur développement vocationnel que ceux qui n’ont de tels desseins. Cette étude est la première tentative pour développer et valider une mesure de l’auto-efficacité du développement vocationnel chez des adolescents chinois. On discute les problèmes liés à un programme général d’orientation et à l’élaboration d’un instrument de mesure dans une perspective interculturelle.Zusammenfassung. Entwicklung eines Instruments zur Selbsteinschätzung eigener Kompetenzen zur Laufbahnplanung für chinesische Jugendliche in Hongkong.In Hongkong wurde der ,,Fragebogen zur Selbsteinschätzung eigener Kompetenzen für die Laufbahnplanung (Career Development Self-Efficacy Inventory – CD-SEI)“ eine Bewertungsskala mit 24 Kriterien entwickelt, mit der Jugendliche die eigenen Kompetenzen für die Laufbahnentwicklung bewerten können. Der Fragebogen deckt 6 Bereiche ab Laufbahnplanung, geschlechtsspezifische Aspekte der Berufswahl, Wahl der Ausbildung, Bewerbung, Methoden der Arbeitsuche, Entwicklung von beruflichen Zielen; damit werden diejenigen Kompetenzen erfasst, die in Hongkong von AbsolventInnen des Gymnasiums (High School) am Übergang in das Beschäftigungssystem benötigt werden. Die Validitätsanalyse auf der Grundlage der Antworten von 6776 SchülerInnen der Klassen 10–13 ergab, dass sich die genauesten Ergebnisse bei Anwendung eines Modells ergaben, dass alle 6 Bereiche unter Betonung eines dieser Faktoren einbezog, wobei allerdings ein Validitätsmodell, dass nur diesen einen herausragenden Faktor einbezog, bereits angemessene Näherungswerte ergab. Die Reliabilitätsanalyse ergab, dass der Gesamtfragebogen und die Teilfragebögen in sich konsistent sind. Die Ergebnisse führen zu der Vermutung, dass Jugendliche zwar ein gewisses, aber kein sehr ausgeprägtes Selbstvertrauen im Hinblick auf ihre Laufbahnentwicklung haben. Jugendliche, die ein Hochschulstudium planten, zeigten ein ausgeprägteres Selbstvertrauen als die anderen Jugendlichen, die kein Studium planten. Dies ist die erste Untersuchung mit dem Ziel, einen derartigen Selbsteinschätzungsfragebogen für chinesische Jugendliche zu entwickeln und zu evaluieren. Der Artikel diskutiert ebenfalls Aspekte einer interkulturellen Perspektive im Zusammenhang mit der Entwicklung von umfassenden Beratungsprogrammen sowie von Beurteilungsinstrumenten.Resumen. Elaboración de un Instrumento de Auto-Eficacia en el Desarrollo de la Carrera de Adolescentes Chinos en Hong Kong. Se ha desarrollado un instrumento de medida con 24 items, el Inventario de Auto-Eficacia en el Desarrollo de la Carrera (IAE-DC), para evaluar la auto-eficacia en el desarrollo de la carrera entre adolescentes de Hong Kong. El IAE-DC abarca seis dimensiones que representan las competencias que los alumnos de secundaria necesitan en su tránsito de la escuela al mundo del trabajo en Hong Kong. Los análisis factoriales realizados a partir de las respuestas de 6776 estudiantes de los cursos 10°–13° demostraron que lo que mejor se ajustaba a los datos eran seis factores primarios con un modelo factorial de orden superior, aunque sólo este modelo factorial general también se ajustaba adecuadamente. Los análisis de fiabilidad confirmaron la consistencia interna de las escalas y subescalas. Los resultados sugirieron que los adolescentes de Hong Kong sentían cierta seguridad, aunque no demasiada, respecto al desarrollo de su carrera. Los estudiantes que tienen decidido ir a la universidad mostraban mayor confianza en su desarrollo profesional que aquellos que no han planificado nada. Este es el primer estudio en el que se ha elaborado y validado un instrumento de medida de la auto-eficacia en el desarrollo de la carrera para adolescentes chinos. Se discuten aspectos relacionados con los programas comprensivos de orientación y con el desarrollo de instrumentos de diagnóstico desde una perspectiva cross-cultural.

儒家价值观的现代意义

与西文基督教伦理根源于对“上帝”的绝对信仰不同,儒家价值观的根基在于与天道合一的人之“仁心本性”,而由此开出的仁、义、礼、智、诚(信)儒家“五常”,是为儒家伦理美德的恒常原则,最终又落实到具体应用的礼制规范层面.从“心性”基础层和“五常”中间层来看,儒家伦理具有普世伦理的意义;而从最外表的礼制规范层面来说,儒家伦理须因时制宜,因革损益,以适应时代与社会的变迁与需求.儒家价值观,对解决伴随科技与知识突飞猛进而日益凸显的价值失落、道德失范问题势必有所帮助,对现代人们的人伦日用仍不失指导意义.
