본 연구에서는 디지털화폐 및 화폐변천과 관련된 문헌들에 대한 내용분석과 분석적 서술을 통해 디지털화폐의 특성을 알아보고, 시대에 따라 변화된 '화폐형태'의 동적인 모습과 그에 따른 패러다임변화를 가져오게 된 사회적 배경을 밝혀내고자 했다. 분석결과 새로운 화폐 출현 초기에는 민간에서의 다양한 시도와 함께 시장 중심의 자율적 통화조정이 이루어졌고, 이후 이윤과 권력의 국가독점을 위하여 정부 중심의 중앙 집중 통화 관리와 조정이 이루어졌다는 것을 알 수 있었다. 디지털화폐는 패러다임 변화를 가져올 새로운 화폐형태의 등장으로 볼 수 있다. 중앙은행이 발행하는 CBDC는 직접형과 간접형 모델이 있으며, 관련 산업 생태계의 변화가 예상되는 만큼 국가나 기업의 전략적 접근이 필요할 것으로 보인다. 민간주도형 디지털화폐인 페이스북 리브라는 가격변동을 최소화하여 화폐로서의 기능에 적합하도록 설계된 스테이블코인으로 실제 상용화에 성공할 경우 전 세계 금융산업에 혁명적 변화를 가져올 것으로 전망된다.

Under the on-going evolution of the COVID-19 pandemic, estimating the economic impact of the pandemic is highly uncertain and challenging. This situation makes it difficult for policymakers, governors, and economic entities to formulate appropriate responses and decision makings. To provide useful information about the effect of the COVID-19 pandemic on the Korean economy, this study examined macroeconomic impact analysis stemming from the pandemic shocks with different scenarios for the Korean economy. Based on three scenarios using the growth rate of 2020 GDP and consumer expenditure patterns, the 2021 GDP by industry sector was forecast with two new approaches. First, the recovering process of the Korean economy from the shock was analyzed by applying a Flex-IO method. Second, a new forecasting approach combined with an IO coefficient matrix was applied to forecast the future GDP changes. The findings of this study are summarized as follows: First, the total GDP growth rate under the Pessimistic Scenario demonstrates less rebound from the shock than that of the Base Scenario. Second, agriculture, culture, and tourism-related sectors that are suffering from the severe losses of COVID-19 showed lower resilience than other different industries. Third, information and communications technology (ICT) industry maintains a stable growth trend and is expected to take the leading role for the Korean economy in the post-COVID-19 and the Industry 4.0 eras. The findings deliver that it needs to analyze how government expenditure responding the shock into the forecasting model, which can be more useful and reliable to simulate the resilience from the pandemic.

e-Health/u-Health has generally been considered as an expansion of current medical and medical relevant segments. However. as e-Health/u-Health has been known to have typical attributes and characteristics of services supporting a physically and mentally well-balanced life of its users, we can rationally assume that e-Health/u-Health can be not only an expansion of the existing medical field but also a result of the complex and sophisticated convergence among diverse industries such as the ICT industry. traditional care-relevant segments, etc. Thus, in this study, we carefully and cautiously consider e-Health/u-Health in accordance with both possible scenarios: 1) an expansion of a typical industry, and 2) a result of a convergence among various industries. The advent of new technologies, rapid development of current technologies, and convergence trends in various fields are creating dramatic innovations in the next generation health services market. Consumerism as a characteristic of c-Health/u-Health can be expected to find a solution of the existing healthcare service problems. In the initial phase. mainly due to the absence of a vanguard, as well as to various legalistic and regulative limitations, the role of the government would be immensely critical for the successful early settlement of the e-Health/u-Health industry. Both the government and private sector need to practice continuous and effective public education and publicity mainly to increase the overall recognition and usability of e-Health/u-Health services. Nursing as a unique professional discipline should be well aware of the new paradigm shift of the healthcare market, and make maximum use of the possibility of this trend to the advent of the professional nursing's new role.

Purpose : The energy saving in a residential building (apartment) sector is known as one of the effective solution of energy reduction. In South Korea, the government has recently reinforced regulations associated with the energy performance of buildings. However, there is a lack of research on the methods for the energy performance diagnosis that is used to analyze the wall thermal performance of the existing apartments. Because a reliable diagnosis is necessary to save the building energy, this study analyzed wall thermal performance of an existing apartment in Seoul. Method : This paper applied two methods for analysis of the thermal insulation performance; HFM(Heat Flow Meter) method and ASTR(Air-Surface Temperature Ratio) method. The HFM method is suggested by ISO9869-1 code to measure the thermal performance. The ASTR method is proposed by this study for the simplified In-situ measurement and it uses three temperature data (interior wall surface, interior and exterior air) and the overall heat transfer coefficient. This study conducted the experiment of an existing apartment in Seoul using these methods and analyzed the results. Furthermore, the energy simulation tool of the building was used to suggest retrofit of the building based on the results of measurements. Result : The error rate of HFM method and ASTR method was analyzed in about 17 to 20%. As the results of comparison between the initial design values of the wall and the measured values, the 26% degradation of insulation thermal performance was measured. Lastly, the energy simulation tool of the building shows 10.8% energy savings in accordance with the construction of suggested retrofit.

One of the prominent challenges of e-government identified in developing countries is low level of ICT literacy and skills of e-government users. For those countries at the nascent stage of e-government development, it is crucial to identify and provide e-skills needed from the demand side. However, prior research has mostly focused on the supply side of e-skills, ignoring the consumption side of e-skills. In addition, no user centric approach for e-skills identification and development for e-service consumption, with respect to the stages of e-government development, have been proposed and validated. The purpose of this article is thus to: 1) Identify skills required for e-services utilization by all participants-citizens, public, and private sector employees-involved in G2C, G2B, and G2E e-government relationships respectively; assuming they are consumers of e-government and to 2) Propose and validate an user-centric approach for e-skills identification and development based on stages of e-government utilizing the Delphi method. As a result of the study, a comprehensive list of e-skills (N = 81) was generated. We found that e-skills required for e-service consumption are not merely technical; they include a wide variety of related skills that can be applied to enhancing e-skills. Therefore, the findings can serve as a standard curriculum for training and educating both citizens and government employees in developing countries. Moreover, the findings of this research may also facilitate international organizations in indentifying and measuring citizens' readiness for e-government in terms of e-skills.

Purpose - In this study, we aim to explore new distribution strategies for sustainable growth in the era of the 4th industrial revolution, focusing on SMEs (small and medium-sized enterprises) in Korea, and suggest ways to upgrade the government's official distribution channel to the next level. Design/methodology - First of all, this paper explored the prior research, the current status of sales support for SMEs, and the changes in the distribution industry due to COVID-19 pandemic. Based on Moon (2016)'s ABCD strategic model - Agility, Benchmarking, Convergence, and Dedication, the study then derived directions in which official distribution channels should move and the new distribution strategy for Korean SMEs to secure competitive advantage. Findings - First, in terms of 'Agility', in order to upgrade official distribution channels, which are currently at some competitive disadvantages compared to private distribution companies, we must quickly introduce technologies for the 4th industrial revolution, such as AI, Big Data, etc., and establish precise strategies to strengthen the capabilities of SMEs. Second, in terms of 'Benchmarking', the use of "Chamelezones" has been increasing to enhance the competitiveness of offline stores in line with recent ontact trends. Therefore, official distribution channels should also benchmark such cases, strengthening their competitiveness by utilizing offline spaces more efficiently and effectively. Third, in terms of 'Convergence', in line with the rapidly changing trend of the times, official distribution channels should also promote active partnerships with media commerce, e-commerce and ICT platforms, as well as cooperation with private retailers, and focus on creating synergy effects through them. Finally, from the perspective of 'Dedication', digitalization should be promoted step by step, finding the sector that can accelerate digital among the value chains of official distribution channels, and continuing to discuss how to digitize it realistically. Originality/value - Based on this analysis, we have presented strategies and implications for innovating official distribution channels for SMEs, which will contribute to enhancing the competitive advantage of official distribution channels in the post COVID-19 pandemic era.
