Korea, one of the members of the Organization for Economic Cooperation and Development (OECD), has been one of the fastest growing countries in the world since World War Ⅱ. However, Korea has recently suffered from an economic crisis which has been mainly attributed to a fluctuating foreign currency rate. The future of Korea relies on how the country prepares and copes with the crises. There have been enormous effort to solve current economic crisis. However, preparation to the anticipated crisis is much more important than solving problems after the crisis. Recently, the virtual crisis preparation team approach appears to be one of the effective alternatives to cope with various crises. The objectives of this study ale to (1) show that crisis preparation is very important factor for the Korean government to one with the current and future crises; (2) to prove that the virtual crisis preparation team is one of the better alternatives to solve crisis; (3) to suggest a virtual crisis preparation team model can be adapted to the Korean situation.

올해 초, 구글(Google)이 SHA-1의 충돌 현상을 입증했다. 이것은 모든 타 암호 알고리즘 역시 안전할 수 없다는 것을 뜻하며, 향후 SHA-256을 사용하는 비트코인도 취약해질 수 있음을 의미한다. 이유인즉슨, 비트코인에서 사용되는 암호 및 해시 알고리즘은 답을 찾기 위해 상당한 시간이 소요되지만, 양자 컴퓨터의 큐비트를 바탕으로 하는 연산처리 능력은 그 시간을 대폭 감소시킬 수 있기 때문이다. 본 논문에서는 이와 같은 양자 컴퓨터가 비트코인에 얼마나 위협적일 수 있는지와 더불어 양자 컴퓨터 출현에 대비하고자 등장한 새로운 암호 화폐인 Byteball 및 QRL코인을 살펴보고자 한다.

가상 화폐가 금융권에 등장한 이후 가상화폐를 얻기 위한 채굴이라는 작업이 각광받기 시작하였다. 하지만 시간이 흐르면서 채굴기를 가동하는데 소모되는 전력보다 채굴에 따른 보상의 양이 적어지면서 수익 구조가 무너지기 시작하였다. 본 논문에서는 태양열 에너지 발전을 통해 가상화폐를 채굴하는 방법을 제안한다. 태양열 발전을 위한 시스템을 설계하고 수익성을 증명하였다. 그 결과 태양열 발전 설비로 생산한 전력을 판매하여 얻는 수익보다 채굴기를 가동하여 얻는 수익이 약 17% 더 많은 것을 알 수 있었다. 채굴 시장의 규모는 블록체인 시장 규모에 비례하여 증가하고 있기 때문에 채굴 시장의 전망도 증가할 것으로 예상된다.

In this study, the present state of fiscal crisis for local governments after IMF is analyzed, firstly. its implications Characteristics of structural reform of finance after IMF bailout in Korea are examined, secondly. Since Korea was shocked by the currency crisis at the end of 1997, its local governments have also faced fiscal difficulties. The Depression of national and local economies led to decreases in tax revenues of local governments. And these shrunken revenues led to their expenditure cuts. Many investment plans were curtailed, and ordinary expenditures were also reduced sharply. The negative influences of the currency crisis on local government's finances can be examined in terms of fiscal revenue, fiscal spending, and debt burden. As a result many local governments are now experiencing fiscal stress, and some of them are even faced with fiscal crisis although the possibility of extreme measures, such as moratoriums or bankruptcies, is very slim. This is due in part to the weight of debt in local governments' budgets having remained small since the debt of local governments has been controlled by the central government. Another reason is that, central government, which functions as a lender of last resort for the local governments, will pay the debt for them. Also, without a legal system which stipulates the adjudication of bankruptcy for municipalities in Korea, local Korean governments have no legal right to declare bankruptcy. Although not a single municipality has fallen into insolvency, yet, this trend will continue to deepen as the recession continues and may lead to a situation where manu local governments fall into virtual bankruptcy in the near future, and its effects on society, as a whole, will be serious. Therefore, measures to prevent and overcome such an extreme situation are necessary, but both short-and long-term policies should be to cope with the current fiscal crisis and to prevent the deepening of the current situation.

Bitcoin, which appeared in 2008, was merely a conceptual virtual currency, but it now enjoys the status as actual money. Bitcoin is an electronic money system that can be traded directly without a central trust institution. Thanks to the popularization of Bitcoin, blockchain technology has become a widespread concern. That technology is expanding not only the currency mechanism, but also a variety of other services. The possibility of a blockchain in relation to actual currency is ongoing. This paper investigates the technological characteristics and social construction of the blockchain by comparing the cases of Bitcoin, Namecoin, and MediBloc among blockchain applications. Namecoin emerged in 2013 is an attempt to replace the centralized Internet Domain Name System(DNS). There has been controversy over that current system for a long time, but replacing the already established system is not easy. Nevertheless, Namecoin has potential as an alternative. Meanwhile, MediBloc is an application that involves distributed management of medical data in South Korea. MediBloc claims that the key producers of medical data are patients themselves. This is to challenge to the question who is a knowledge producer of medical data. Through these three cases, it has discussed that blockchain technology does supports to form more democratic decision-making or simply provide a technical solution as automation. As a citizen, we can intervene in the realization of blockchains by presenting social agenda. This will be a method of the social construction of technology.

This study was conducted to find ways to restore the domestic medical tourism industry, which was seriously hit by a sharp drop in foreign patients after the COVID-19 Pandemic. Kendall's W verification was used by asking expert panel for keyword advice by ranking. The conclusion of the study is that institutions attracting foreign patients need an opportunity to turn the crisis situation into an opportunity by expanding treatment for severe foreign patients. In addition, it is possible to gain familiarity and trust in hospitals in situations where it is difficult to visit overseas through virtual and augmented reality, and to prevent the risk of infection and protect patients in the untact era. In addition, the blockchain can maintain patient information supplementation, share it safely, minimize customer inconvenience by using payment means using virtual currency, and finally, smart healthcare can manage and provide information to patients regardless of location.
