Research on post-colonial curricula in non-Western countries continues to expand, with contributions from many scholars around the world. Many of these authors argue that post-colonial theories and the implications of those theories can help elucidate how colonial hegemony and ideology have affected the dominant discourse regarding curriculum studies discourse in non-Western nations. Despite the efforts that have been made, the field of curriculum studies in South Korea lacks context-relevant post-colonial perspectives and practical approaches to developing new post-colonial knowledge based on its own language, culture, history, and epistemologies. This article explores the life's work of one Korean post-colonial curriculum scholar. Based on a document analysis and an in-depth interview process, the following discussion conceptualizes three themes related to post-colonial curriculum studies: (1) production of indigenous qualitative research texts, (2) identification of new curriculum phenomenon from the local, and (3) creation of new concepts and languages for international curriculum research. This analysis can inform how curriculum scholars in South Korea and other non-Western regions approach post-colonial curriculum research in a specific nation.

In this paper, we proposed methods to accurately predict pixel values by effectively using local similarity, curved surface characteristics, and edge characteristics present in an image. Furthermore, to hide more confidential data in a cover image using the prediction image composed of precisely predicted pixel values, we proposed an effective data hiding technique that applied the prediction image to the conventional reversible data hiding technique. Precise prediction of pixel values greatly increases the frequency at the peak point in the histogram of the difference sequence generated using the cover and prediction images. This considerably increases the amount of confidential data that can be hidden in the cover image. The proposed reversible data hiding algorithm (ARDHA) can hide up to 24.5% more confidential data than the existing algorithm. Moreover, it is not possible to determine the presence of hidden confidential data in stego-images, as they possess excellent visual quality. The confidential data can be extracted from the stego-image without loss, and the original cover image can be restored from the stego-image without distortion. Therefore, the proposed algorithm can be effectively used in digital image watermarking, military, and medical applications.

PurposeAging is a global phenomenon for many countries, and South Korea has become the fastest aging country in the world. The purpose of this study is to identify and validate a representative typology of older Koreans based on their lifestyle and value orientations. This study also makes a longitudinal comparison of these segments in two waves using similar survey data collected in 2009 and 2017 and examines any meaningful changes that occurred during the periods.Design/methodology/approachUsing survey data collected from 750 older adults living in four major cities in Korea, this study conducted factor and cluster analysis to identify lifestyle segmentation of elderly Koreans. Both descriptive and mean comparison analyses are followed to characterize the segments with relevant demographic and behavioral variables. In addition, this study makes a longitudinal comparison of these segments in two waves (2009 and 2017) and examines any meaningful changes that occurred during the periods.FindingsSix distinctive lifestyle segments of elderly Koreans are identified. The longitudinal comparison reveals some changes that occurred during the period. The level of importance of values and things to own has been declined during the period on most of the aspects, which can be interpreted that older Koreans become more realistic and practical. The level of life satisfaction between the two periods turned out to be similar. However, satisfaction in material comfort and health has been improved during the period, which means that the perception of their financial and physical aspects has been improved over the years.Originality/valueFirst, based on Tempest et al.'s three grey discontinuity framework (2002), the segmentation model provides comprehensive coverage of psychological transitions experienced by older people due to economic, physical and mental discontinuities with age. Second, this might be the first longitudinal study to examine the changes in segmentation over time in terms of the lifestyle of older adults. Practically, the findings of this study provide useful insights for policymakers in developing aging-related policies as well as for marketers who are interested or currently doing business in Korea or Asian consumer markets.

Temporary migration is a growing global trend, but there is little research on its representation in the media of origin countries. This paper fills this gap by examining how temporary migration is framed by using a longitudinal anal- ysis that focuses on the representation of South Korean participants in the Australian Working Holiday Program in South Korean newspapers from 2000 to 2018. This paper explores the role that South Korean newspapers have played in constructing pro-migration discourses and representing the pro- gram, its participants, and their experiences while considering the social and political environments. Key focus areas identified include a "culture of migration," national interest, economic imperatives/employment, and "victimization."
