Purpose: This study aimed to establish the translation adequacy and examine the psychometric properties of FaceMask Use Scale (FMUS). Methods: This methodological study employed a cross-sectional design with repeatedmeasures. Phase 1 examined the equivalence and relevance of English and Chinese versions of FMUS. Phase2 examined the internal consistency, stability and construct validity. Different sample batches (213 universitystudents and 971 general public) were used appropriately for psychometric testing. The 2-phase data were collectedbetween January and April 2017. Results: In Phase 1, the semantic equivalence and relevance (item- and scale-levelcontent-validity-index=100%) was satisfactory. Furthermore, from 133 paired test-retest responses, the quadraticweighted kappa (.53~.73, p<.001) and Intraclass Correlation Coefficient (ICC=.81) between the English andChinese version of FMUS were satisfactory. In Phase 2, FMUS demonstrated satisfactory internal consistency(Cronbach’s ⍺=.80~.81; corrected item-total correlation coefficients=.46~.67) and two-week test-retest stability(ICC=.84). The known-groups method (t=3.08, p<.001), exploratory (71.10% of total variance in two-factor model)and confirmatory factory analysis (x2/df=4.02, Root Mean Square Residual=.03, Root Mean Square Error ofApproximation=.06, Goodness of Fit Index=.99, Comparative Fit Index=.99) were all satisfactory for establishingthe construct validity. Conclusion: The FMUS has an equivalence Chinese and English versions, satisfactoryreliability and validity for measuring the practice of face mask use. This poses clinical and research implications forthose community health nurses who works on respiratory protection. Further research should be conducted on the‘negligent practice’ of FMU.
Holistic Reform of the Mathematics Curriculum - the Hong Kong Exoperience

The Hong Kong mathematics curriculum has launched its reform in recent years. It was the first time that a holistic review of syllabi from Primary 1 through Secondary 7 was made. The curriculum development agency also decided to base the reform on sound pedagogical foundations. That was assisted with academic research where the views of various stakeholders were investigated in detail. Surveys were conducted with students, parents, teachers, employers, university professors, and curriculum designers and they give a full picture of mathematics teaching and learning in Hong Kong. The rich data collected should shed light on the development of mathematics curriculum in other regions with similar socio-cultural and educational settings.
Changing Students` Conceptions of Mathematics through the Introduction of Variation
( Ngai Ying Wong ),( Chit Kwong Kong ),( Chi Chung Lam ),( Ka Ming Patrick Wong ) 한국수학교육학회 2010 수학교육연구 Vol.14 No.4
Some 400 Secondary One (i.e. seventh-grade) students from 10 schools were provided with non-routine mathematical problems in their normal mathematics classes as exercises for one academic year. Their attitudes toward mathematics, their conceptions of mathematics and their problem-solving performance were measured both in the beginning and at the end of the year. Hierarchical regression analyses revealed that the introduction of an appropriate dose of non-routine problems would generate some effects on the students` conceptions of mathematics. A medium dose of non-routine problems (as reported by the teachers) would result in a change of the students` conception of mathematics to perceiving mathematics as less of "a subject of calculables." On the other hand, a high dose would lead students to perceive mathematics as more useful and more as a discipline involving thinking. However, with a low dose of non-routine problems, students found mathematics more "friendly" (free from fear). It is therefore proposed that the use of non-routine mathematical problems to an appropriate extent can induce changes in students` "lived space" of mathematics learning and broaden their conceptions of mathematics and mathematics learning.

Background: The year 2022 marks the 30th anniversary of heart transplant service in Hong Kong (HK). In this study, we describe prevailing trends and outcomes of advanced heart failure (AHF), including heart transplantations (HTx), in HK over the past 30 years. Methods: Trends in heart failure prevalence in HK from 1993 to 2021 were analyzed based on data from the Hospital Authority Clinical Data and Reporting System. All AHF patients referred for HTx consideration between 1992 and 2021 were reviewed. The bridge-to-transplant (BTT) utilization of short-term mechanical circulatory support (ST-MCS) devices, including venoarterial extracorporeal membrane oxygenation (VA-ECMO) and durable left ventricular assist devices (LVADs), from 2010 to 2021 was reviewed. Results: Overall, 237 heart transplants were performed in HK, with 10-year posttransplant and median survival of 68.1% and 18.7 years, respectively. An increase in AHF clinic referrals was correlated with increasing heart failure prevalence (R2=0.635, P<0.001). In total, 146 referrals were made for ST-MCS, and an observed increase in ST-MCS referrals was correlated with increasing VA-ECMO utilization (R2=0.849, P<0.001). Among 62 patients accepted for AHF therapy, those with durable LVAD implementation had better 1-year survival (71.5%) than those receiving an extracorporeal CentriMag (Levitronix) device as BTT (40%, P=0.008). In total, 143 LVADs were implanted, with 130 as BTT or bridge-to-candidacy (BTC) methods. The survival rate among the 130 BTT/BTC LVAD patients resembled that of HTx recipients (73.8% vs. 69.8% at 9 years, P=0.296). Conclusions: The burden of AHF management has increased and gained complexity over the past 30 years in Hong Kong.
