Abstract Anticipatory governance (AG) is defined as a “system of systems” that employs foresight to create future plans and execute relevant actions. Recently, various frameworks of AG have been introduced, but there is little practical information available for newcomers on how to do this. This research conducted a framework-based comparative country analysis to provide lessons learned for newcomers in the sphere of foresight-linked AG. By evaluating the AG levels of Finland, the UK, the Nether

Background: Korea has achieved health policy objectives in pandemic management so far, namely minimizing mortality, flattening the epidemic curve, and limiting the socio-economic burden of its measures. The key to the Korean government's success in combating COVID-19 lies with the latest digital technologies (DTs). The prompt and effective application of DTs facilitates both containment as well as mitigation strategies and their sub-policy measures. Methods: This article uses an experiential ana

We propose a discrete wavelet transform (DWT) based watermarking method, which can be conveniently integrated in the forthcoming JPEG-2000 baseline. Conventional DWT-based watermarking techniques insert a watermark into the coefficients after the transform is completed, while the proposed method inserts a watermark into the coefficients obtained from the ongoing process of lifting for DWT. The proposed method allows us to determine selectively frequency characteristics of the coefficients where

Abstract Universal healthcare systems have undergone a severe stress test in the form of the ongoing COVID-19 pandemic. With respect to the system-embedded allocation of decision-making powers and responsibilities among actors, different modalities have been revealed in the COVID-19 responses of South Korea and the UK, respectively. This article compares and analyzes how these two countries’ healthcare systems have reacted to COVID-19. Although both have implemented similar responsive measures,

Public interests in coming futures of Korea continue to be increasing. Fears on uncertainties and pending challenges as well as demands on a new but Korea-own development model trigger a quantitative increase of futures research and relevant organizations in both public and private. The objective of this paper is to review history of futures studies and national development plan and strategy linked with foresight along with its challenges and recommendations. This paper identifies drawbacks and

This paper proposes a QIM watermarking scheme for a digital image with two adaptive quantization step-sizes. After calculating an edge map of the image, in a flat region a small step-size is applied and in an edge region a large step-size is used. The threshold between flat and edge is decided empirically and watermark blocks are embedded repeatedly into the image using different step-sizes. In the detection process, we show how to estimate the threshold value by ACF (auto-correlation function).

In order to derive accurate investment priority results for current disaster prevention projects, it is necessary to introduce a methodology that has improved upon the existing economic evaluation model. In this study, we used the Korean damage and loss function, which was newly developed in an R&D project of the Ministry of the Interior and Safety (MOIS). In the case of indirect benefit calculations, indirect benefit items that can be calculated for cost value were selected and developed to be

The current age is characterised by many as secular, and a source of such a characterisation can be found in the Nietzschean claim that thoughts about there being some ultimate reality have to be jettisoned, and human existence and the world need to be embraced as they are. That claim is renewed by some secular thinkers who insist that education has to be reconceived in ways congenial to the new age. It is argued that central to their logic is the dichotomy between the religious and the secular

본 연구에서는 터널 시공 중 굴진면에서의 붕괴 위험을 판단하여 작업자의 안전을 확보할 수 있는 굴진면 안전감시시스템을 개발하였다. 이 시스템은 실시간으로 측정되는 굴진면 변위를 x-MR 관리도기법으로 실시간 분석함으로써 굴진면의 이상 거동을 감시할 수 있다. 또한 관리 기준을 초과하는 측정치의 개수와 이동 범위 k를 비교하여 굴진면의 이상 거동과 작업 과정에서 발생하는 오류를 구분할 수 있도록 오경보 판단 알고리듬을 개발하였다. 본 연구결과는 위험지반 구간에서의 굴진면의 실시간 거동 감시에 적용되어 작업자의 피해를 최소화 할 수 있을 것으로 판단된다. In the present study, a face safety monitoring system was developed that will enable judging collapse risks on faces during tunnel construction to secure workers' safety. This system enabl
