SummaryBackgroundComputed radiography (CR), digital radiography (DR) and biplanar radiography (EOS™ imaging system) are common imaging tools for radiographic evaluation of adolescent idiopathic scoliosis (AIS). The effect of imaging methods in relation to later-on Cobb angle measurements on radiographs is not yet quantified. The study aimed to examine the compatibility between CR, DR and EOS for scoliotic quantification by evaluating the reliability, agreement of different imaging methods, and assessing the prediction performance for EOS measurement from that of CR and DR.MethodA flexible spine phantom was used to simulate 32 different scoliotic curves ranging from 10° to 60°. Each curvature was imaged using DR, CR and EOS systems accordingly. Each of the six observers independently measured Cobb angle twice on each image at a two-week interval. Intraclass correlation coefficient (model 2 and 3), Bland-Altman plot and linear regression analysis were completed to evaluate the reliability, agreement, and the prediction of Cobb angle measurement, respectively.ResultsReliability analysis showed excellent intra-observer reliability (Intraclass correlation coefficient >0.9) for each observer and good inter-observer reliability (Intraclass correlation coefficient = 0.84 for EOS; 0.739 for CR; 0.877 for DR) for each method. Bland-Altman plots demonstrated good agreement between imaging methods without fixed or proportional bias. Excellent coefficient of determination was achieved, with 0.980 for CR versus EOS measurements, and 0.973 for DR versus EOS measurements.ConclusionsRadiographs produced by all of the three methods can provide reliable and accurate Cobb angle measurements for scoliosis assessments. None of the methods systemically underestimates or overestimates the Cobb angle measurement. Additionally, all of the evaluated methods are satisfactory in obtaining images for Cobb angle measurement in AIS. However, the 3D post-processing techniques offered by EOS should also be taken into consideration as it takes a vital role in treatment and monitoring of 3D deformity in the case of scoliosis.The translational potential of this articleIn view of the limited availability of biplanar radiography (EOS™ imaging system), computed radiography and digital radiography are demonstrated to be reliable alternatives in scoliosis monitoring as evident in the reliability, agreement and prediction of Cobb angle measurement.

Cultural heritage plays an important role in the creation of creative cities, giving them a new lease of life and generating employment opportunities and local economies in the process. The revitalisation and development of cultural heritage and intangible cultural heritage have become a major part of national development policies worldwide. This study adopts a multiple case analysis approach. Four cultural heritages of three destinations in East Asia (Hong Kong, Macau and Taiwan) were selected as case studies because they have all adopted a public–private partnership approach to the conservation and reuse of historic buildings. In this study, semi-structured interviews were conducted and secondary data collected from a variety of sources to bring the findings of this study closer to the practical development of cultural heritage. Base on Five Forces analysis, we propose an “Extended Five Forces” model of cultural heritage. The new component, i.e., historical landscapes and cultural sustainability, is proposed to expand the theoretical foundations of the sustainable management of cultural heritage. The findings show how they can collaborate with communities to create value and gain a sustainable competitive advantage on a global scale and contribute to the sustainable management of cultural heritage in Asia.

The aim of this research is to identify the digital technology impact and experience innovation of cultural heritages in the context of the epidemic. The authors created an analytical framework and used a qualitative exploratory multi-case study of three cultural heritages in Taiwan. The findings indicate that digital technology has facilitated further innovations in cultural heritages under the epidemic to be closer to consumers’ daily life and more connected with the young generation. Compared to traditional cultural heritages, profit-making cultural heritages need sales of its products to sustain operations, while live streaming, which is interactive, is rising as a new way to promote sales. Using multiple digital platforms can maintain consumers’ interest in the cultural heritages, encouraging follow-up visits and thus resulting in more traffic online and offline. This paper illustrates the advantages of digital technology in the context of the epidemic, highlighting the innovative technology of live streaming and social platforms introduced that are different from the traditional cultural heritages.

For cultural heritage around the world, the servicescape is a key factor that affects the visitor’s experience and engagement. The purpose of this article is to rummage about the current situation of commercial cultural heritage in Asia, bringing consult to the design of cultural heritage. Through an exploratory study, this paper examines how the experiential spaces of the Hayashi Department Store and Tai Kwun are designed and established. This article examined the link between service design and customer experience through a service design perspective. This study further extended the that managers can enhance the visitor experience through service design and experience innovation concepts to create a good reputation and customer willingness to return. The case comparison revealed three important factors in designing experience spaces: Cross-domain teams, heritage restoration and people engagement.
