The relevance of the published study lies in the fact that since the introduction of the first Global Distribution System, new information and communication technologies have constantly been changing the tourism industry. In the context of a current digital environment, travel agencies can't avoid participating in digital transformation processes aimed at rethinking operational models, skills, and organisational structures in the regions. This publication aims to present and provide a critical overview of digitalisation processes in tourism development in the regions of the Russian Federation, as well as to reflect on the challenges to the widespread digitalisation processes in the regional tourism sector. The subject of research is digitalisation processes, as they radically transform the modern tourism industry, in the regions as well. The pragmatic research paradigm was considered the most appropriate for the study of tourism digitalisation processes in the regions, as it does not require the selection of a specific theoretical basis for data collection. The pragmatic approach forms an alternative to classical theoretical approaches and serves as a particular type of grounded theory, combining both inductive and deductive methods. No software was used for the inductive part of the analysis. The deductive part was conducted using the qualitative data analysis software Nvivo 11. Given the wide diversity of interested parties in the regional tourism digital area, a stratified purposive sampling method was preferred due to its ability to adequately represent the full picture of the phenomenon under study. The selection and stratum criteria were chosen to maximise the representation of different perspectives in the regional tourism digital area. The novelty of the study is due to the digitalisation processes, with an implication of new needs, while opening up promising opportunities for more productive tourism business in the regions of the Russian Federation. Currently, e-tourism in the Russian Federation has become a subject of lively debate among scholars and practitioners. However, the involvement of advanced digitalisation technologies in the field of information processes in the regions of the Russian Federation is of a very sporadic character.

There are two aspects of digital trade: the digitalisation of goods/services being traded and the digitalisation of the transactional act. Digital data (i.e. machine-readable industrial data and transactional data) is the major driving force for both aspects of digital trade. Digital data is a non-rivalrous input, whether for production or marketing activities, and is thus able to be used by many firms or government agencies without limiting the use of others. Digital platforms provide online infrastructure for the interactions between groups, for instance, consumers and producers. The externality effect refers to the situation in which prosperity in one group on a given platform will improve the returns of other groups on the same platform. In the era of the data-driven economy, strategic trade policy can involve data-related policies. The major objective of these policies is to improve the competitiveness of domestic firms. For instance, firms may be subsidised if they use cloud services provided by specific platforms. This strand of strategic trade policies might be useful for increasing the competitiveness of small-and medium-sized enterprises (SMEs) via the digitalisation of production/marketing processes. Alternatively, strategic trade policy may also exploit the externality effect via platform economy-related policies. Further, some countries may form data coalitions to facilitate cross-border data flow. This paper uses cases in Asian countries to illustrate which role these strategic trade policies can play in the digital economy.

The advent of digitalisation has transformed economies into more integrated, but increasingly complex systems. This new trend has brought dynamic changes in the manufacturing sector through advanced ICT infrastructure, smart factories, digitally-controlled logistics, and skilled ICT-labour. The impacts of the digital economy on manufacturing could be best illustrated through "Industry 4.0." With this wave of technological advancement, countries aim to establish an industrial ecosystem where every manufacturing process and function is connected and interacts through digital networks. Industry 4.0 presents opportunities for Emerging Asia, as the region has emerged as a fast-growing manufacturing hub and particularly a production base for ICT goods. However, growing production capacity, increased exports, and increases in FDI in the field of ICT goods manufacturing have so far contributed little to the development and diffusion of ICT. A huge gap exists in the ICT uptake amongst countries and between small and large firms. This paper highlights the level of Industry 4.0 readiness of Emerging Asia and key factors that determine its enhancement.

원자력산업 섹터는 에너지 산업 섹터에서 가장 선진화된 기술을 도입했으다. '디지털화'에 대한 대중 인식은 일정 부분 왜곡되어 있다. 젊은 소비자들은 원자력을 구시대의 산업으로 인식한다. 소형 원자로를 비롯한 최근 기술 발전을 고려할 때 이러한 인식은 굉장히 잘못되었다. 일반 대중은 원자력산업의 디지털화에 대해 회의적이나 원자력산업 종사자의 의견은 다르다. 25~34세의 원자력산업 종사자들 중 87%는 원자력산업의 디지털화 및 자동화에 대해 '긍정적인 변화'라고 응답했다.

Digital images of cultural relics captured using line scan cameras present limitations due to uneven intensity and low contrast. To address this issue, this report proposes a colour linear array image enhancement method that can maintain a constant colour. First, the colour linear array image is converted from the red-green-blue (RGB) colour space into the hue-saturation-intensity colour space, and the three components of hue, saturation, and intensity are separated. Subsequently, the hue and saturation components are held constant while the intensity component is processed using the established intensity compensation model to eliminate the uneven intensity of the image. On this basis, the contrast of the intensity component is enhanced using an improved local contrast enhancement method. Finally, the processed image is converted into the RGB colour space. The experimental results indicate that the proposed method can significantly improve the visual effect of colour linear array images. Moreover, the objective quality evaluation parameters are improved compared to those determined using existing methods.

디지털 전환(digital transformation)은 디짓화(digitisation)와 디지털화(digitalisation)의 경제적 및 사회적 효과를 의미한다. 디지털 전환은 경제/사회 발전 및 삶의 편의성을 향상시키는 유용한 도구로 작용하지만 부정적 영향(개인정보 오남용, 윤리문제 야기, 사회적 격차 심화 등)을 미칠 수도 있는 양면성을 보유하고 있다. 한편 정부는 산업 경쟁력 및 기술 패권 확보 등을 위하여 디지털 전환 촉진정책은 적극적으로 추진하고 있는 반면, 디지털 전환 관련 위험이슈에 대한 이해와 이를 방지할 수 있는 정책 추진에는 상대적으로 소극적인 상황이다. 이에 본 연구는 디지털 전환이 초래할 수 있는 미래사회 위험이슈를 Embedded Topic Modeling 방법론 기반의 언론기사 빅데이터 정량분석으로 체계화 및 구체화하고, 정책적 대응 방향을 제시하였다. 이를 위하여 먼저 주요국의 디지털 전환 역기능 세부 이슈들을 규명하였다. 다음으로 디지털 전환의 핵심 기술인 인공지능을 중심으로 주요국과 한국의 디지털 전환 역기능 세부이슈를 구체화하고, 비교분석하였다. 아울러 분석결과들을 종합하여 향후 정부의 디지털 전환 역기능 대응 정책 수립 방향을 제시하였다. 분석 결과에 근거한 정책적 함의는 다음과 같다. 첫째, 디지털 전환의 역기능은 기술 분야에만 한정되어 나타나지 않고 국가안보 및 사회 전반에 영향을 미치기 때문에 정부는 디지털 전환의 순기능 촉진뿐만 아니라 역기능 대응을 위한 정책도 마련해야 한다. 둘째, 디지털 전환의 미래사회 위험 세부이슈들은 국가에 따라 상이하게 나타나므로 정부는 국가적/사회적 맥락을 고려하여 디지털 전환 역기능 대응 정책을 수립해야 한다. 마지막으로 정부는 이해관계자들의 혼선을 최소화할 수 있도록 디지털 전환 역기능 대응 정책의 큰 방향을 설정하고, 실효성 있는 정책 수단을 마련해야 한다.

In this paper we study the theory of knotoids and braidoids and the theory of pseudo knotoids and pseudo braidoids on the torus T. In particular, we introduce the notion of mixed knotoids in S², that generalizes the notion of mixed links in S³, and we present an isotopy theorem for mixed knotoids. We then generalize the Kauffman bracket polynomial, <; >, for mixed knotoids and we present a state sum formula for <; >. We also introduce the notion of mixed pseudo knotoids, that is, multi-knotoids on two components with some missing crossing information. More precisely, we present an isotopy theorem for mixed pseudo knotoids and we extend the Kauffman bracket polynomial for pseudo mixed knotoids. Finally, we introduce the theories of mixed braidoids and mixed pseudo braidoids as counterpart theories of mixed knotoids and mixed pseudo knotoids, respectively. With the use of the L-moves, that we also introduce here for mixed braidoid equivalence, we formulate and prove the analogue of the Alexander and the Markov theorems for mixed knotoids. We also formulate and prove the analogue of the Alexander theorem for mixed pseudo knotoids.

방송과 통신의 융합으로 인해, 전 세계의 TV와 라디오 방송사들은 전면적인 디지털 방송화를 위해 매진하고 있다. 이러한 흐름 속에서 우리나라는 아날로그 방송신호를 전면 중단해야만 하는 디지털 전환정책을 2012년까지 완수하여야 한다. 보고서에 따르면 현재 대략 30%정도의 디지털 전환률을 보이고 있다고는 하지만, 그 조차도 관련 기관의 공식적인 집계는 아니다. 이에 비해 우리나라와 같은 해인 2012년 디지털 전환을 완료해야 하는 영국의 경우 2008년 2분기 현재 88%의 디지털 전환률을 보이고 있는 것은 비교될 만하다. 현재 상태로 우리나라의 디지털 전환은 장밋빛 미래를 기대하기 힘들 뿐 아니라, 위태로운 지경에 놓여 있다고 볼 수 있다. 본 연구는 미래학적인 관점에서 우리나라의 디지털 전환의 미래를 예측하여 보고, 시청 행태에 영향을 미칠 수 있는 가능성을 찾고자 한다. 분석을 위해서는 미래 예측에서 유용하게 활용되는 퓨처스휠 기법을 적용하였다. 결론에서는 우리나라의 급박한 디지털 전환에 대처하는 몇 가지 시나리오를 제시하였다.
