Purpose - The digital service trade has become an important driver of the global service trade. The main purpose of this study is to explore the influencing factors of digital service exports from China and Korea to RCEP sample countries respectively, and to comprehensively study the export potential of China and Korea to RCEP countries, so as to provide theoretical guidance and a decision-making reference to promote digital service trade exports and digital economy development in China and Korea. Design/methodology - First, the stochastic frontier gravity model was improved by introducing nonefficiency factors affecting digital services trade, extending the gravity model of traditional services trade exports to digital services trade exports. Secondly, the panel data of China and Korea for the eight sample countries of RCEP from 2011 to 2021 were adopted for the empirical analysis of digital service export potential by a stochastic frontier model. Findings - China's economic growth plays a role in increasing China's digital service trade exports, while Korea's economic growth does not play a significant role in increasing Korea's digital service trade exports. However, the economic growth of trading partner countries can play a significant role in boosting the digital service trade in both China and Korea, and comparison shows that Korea has higher resilience in the digital services trade than China. In addition, the market size of target countries plays a positive role in promoting the digital service trade exports of both China and Korea, and the increase in the value-added share of services in target countries will lead to a decrease in the digital service trade exports of both China and Korea. Originality/value - This study is innovative in terms of research perspective and method. Academic research on the export potential of international trade has been extensive, but most studies are based on the perspective of the goods trade, fewer studies are based on the perspective of the service trade, and there are almost no studies based on the perspective of digital service trade. There is a gap based on the comparative analysis of the export potential of the digital service trade between China and Korea. This study extends the gravitational model of traditional service trade exports to digital service trade exports to comparatively analyze the export potential of China and Korea to RCEP countries. This study addresses this limitation by analyzing a comparative analysis of the digital service trade export potential of China and Korea.

Purpose The purpose of this study is to identify the role of digital shadow work(DSW) in the psychological mechanism that controls using and purchasing digital device accessories. More specifically, it is to reveal how the digital device user's perception of DSW is formed and how the formed DSW affects purchase and what results it will bring. Design/methodology/approach Ground theory method(GTM), one of qualitative appoaches, is adopted as research methodology. By interviewing total twenty five users, the data are analyzed by open coding amd axis coding. Two core codes are selected by selective coding and interpreted by DSW theory. Findings We find concern for potential DSW and generation of new DSW. Concern for potential DSW lead to the purchase of accessorie which would be supposed to reduce potential DSW. During purchasing accessories, quest type DSW, which provices flow experience and expertise, could be genterated. This means that there would be dynamics of DSW in the purchase process of digital device accessories.

The objective of this research is to suggest new geometric possibilities in digital architecture by investigating the characteristics of hybridization in digital geometry. The research begins with theoretical background research such as defining hybridization, investigating hybrid thinking, and studying the theory of digital geometry, along with the four conceptual characteristics of hybridization that could be drawn, such as temporality, liquidity, complexity, and connectivity. Based on these characteristics, the generative method of hybrid digital geometric languages such as Blob, Particle, Morph, Loft, and Boolean was analyzed with case research in contemporary digital architecture. As a result, diverse hybrid geometric keywords were extracted; these keywords suggest potential meanings of hybridization such as accidentality, mobility, diversity, and identity. Different elements represent the "mobility" in time by the force and wave, and they are "accidentally" combined in gradual change. The united species in "diverse" characters are seamlessly connected and emerge as a new "identity." The research maximizes the generative possibilities in digital geometry and provides a theoretical basis to apply the digital hybrid methods to architectural design by suggesting the potential meanings and possibilities in hybridization.

본 논문에서는 디지털교과서의 활용이 인터넷 중독 잠재적 위험군과 일반 사용자군에게 각각 어떤 영향을 미쳤는지를 분석하였다. 이를 위해 먼저 디지털교과서를 사용하는 연구학교의 학생들에게 인터넷 중독 검사를 실시하여 인터넷 중독 잠재적 위험군과 일반 사용자군으로 선별하였다. 그리고 설문조사를 통하여 디지털교과서 활용이 인터넷 중독과의 관련하여 미친 영향을 조사하고 두 집단 간의 차이를 비교 분석하였다. 또한, 인터넷 중독 잠재적 위험 사용자군이 생각하는 디지털교과서 활용과 인터넷 중독의 관련성에 대해 객관성을 확인하기 위하여 디지털교과서를 사용하지 않는 인터넷 중독 잠재적 위험군을 선발하여 동일한 조사를 실시하고 그 차이를 비교 분석하였다. 그 결과, 인터넷 중독 잠재적 위험 사용자군이 일반 사용자군보다 디지털교과서에 대한 활용 시간과 학습 선호도가 더 낮은 것으로 나타났고, 인터넷 사용빈도와 건강 문제는 디지털교과서를 사용하지 않는 인터넷 중독 잠재적 위험군과 동일한 경향을 나타냈다. 따라서 디지털교과서 사용이 인터넷 중독 잠재적 위험군에게 더 큰 영향을 미쳤다고 볼 수 없으나 해당 학생들은 디지털교과서의 사용으로 인해 본인들이 인터넷 중독에 대한 악영향을 받았다고 생각하는 경향이 있어 본 논문에서는 디지털교과서 사용에 앞서 정보통신 윤리교육을 먼저 실시하여 올바른 컴퓨터와 스마트기기 사용 태도를 기르도록 할 것을 제안하였다.

China launched the Digital Silk Road (DSR) in 2015 as part of the existing Belt and Road Initiative (BRI) to expand its influence in digital and technological development across Asia, Europe, and Africa. Southeast Asia is one of the key targets of the Digital Silk Road due to its geographical proximity to China and the rapid growth of the digital sphere. Although the DSR opens several potential opportunities for the Association of Southeast Asian Nations (ASEAN) member states to foster the digitalization process in the region, how each country reacts to projects under the DSR is varied. Secondly, Vietnam is the only ASEAN member state that has not signed any official agreement under the BRI framework, and thirdly, Vietnam opted out of Huawei technology. This paper aims to understand the perspective of Vietnam and how Vietnam has responded to the growing technological presence of China in Southeast Asia until 2021. By using qualitative methods, the author argues that the DSR has allowed Beijing to overcome the limitations of the original strategy, BRI, and strengthen its influence in the field of information and communication technologies, particularly fifth-generation (5G) telecommunications. Furthermore, the paper examines Vietnam's digital development and digital diplomacy and how the Vietnamese government has responded to DSR projects. In light of both the potential threats and economic benefits that the DSR has brought to Vietnam and Southeast Asian countries, in the last section, the policy implications for cooperation are discussed.

Polarography is a subclass of voltammetry where the working electrode is a dropping mercury electrode. More, I developed the experiment for raising up mercury electrode. In Voltammetry, information about an analyte is obtained by measuring the current as the potential is varied at oxidation-reduction reaction. A plot of current vs. potential in a polarography experiment shows the current oscillations correspoding to the drops of Hg falling from the capillary. The drops growth causes capacitive and faradic current. These changing current effects combined with experiments where the potential is continuously changed can result in noisy traces. The raising up type improved upon the method of dropping in hardware. In reduction of the noise, moving average smoothing method have been used. But the other procedure is introduced based on Fourier transformation. So FFT and IFFT engine was implemented and installed in my experiment. However, after experimentation, peak height as the measuring parameter gave a good linear relationship to concentration. The resolution of potential peaks of various kinds, using Zn and Cu as the example, was improved using the smoothing method.

The divide between the "digital" economy and the traditional "physical" economy is outdated. In fact, we are in a transition to a singular economy. This paper classifies economic objects (including actors) as either physical or virtual and argues that due to emerging technologies, these objects are interacting with each other in both physical and increasingly digital spheres in tandem. This paper recognizes the elemental difference between atoms and bytes but argues that physical and digital economic activities are becoming inseparably intertwined. Furthermore, arbitrarily dividing the economy into two categories - one "physical" and the other "digital" - distorts the overall view of the actual execution of economic activity. A wide range of innovations emerging concurrently is fueling the transition to a singular economy. Often referred to as the elements of the Fourth Industrial Revolution (4IR), four emerging technological areas are reviewed here: distributed ledger technology, artificial intelligence/machine learning/data sciences, biometrics and remote sensor technologies, and access infrastructure (universal internet access/electricity/cloud computing). The financial services sector is presented as a case study for the potential impact of these 4IR technologies and the blurring physical/digital line. To reach the potential of these innovations and a truly singular economy, it requires the concurrent development of social, organizational, and regulatory innovations, though they lag in terms of technological progress thus far.
