Recently, the world has been considering hydrogen energy as the primary energy transition means to achieve carbon neutrality by 2050. In order to achieve the goal of reducing greenhouse gas emissions, Korea is also promoting a clean hydrogen economy. However, it is necessary to introduce various clean hydrogen from overseas so that the projected demand can not meet the domestically produced. For this study, we conducted the policy comparison approach between countries other than the generally considered technical and economic approaches. The finding proposes the direction of bilateral cooperation for a strategy of securing overseas clean hydrogen from a geopolitical perspective. Germany was a target country for the policy comparison since it has a high proportion of manufacturing, like Korea, and is taking the lead in the renewable-based energy transition policy. According to the survey and analysis of the policy establishment status and new projects of the two countries, Germany is promoting bilateral international cooperation in the hydrogen area with about 33 countries based on 7 types of activities. In comparison, Korea is involved in bilateral cooperation with about 12 countries on relatively few activities. Among the types of bilateral cooperation, R&D cooperation with advanced countries for hydrogen technology was a common activity type. Germany preemptively promotes cooperation for demonstration and commercialization, considering geopolitical means and strengthening manpower training and assistance on policy and regulation to preoccupy the market for the future. Therefore, it is necessary to consider establishing a network of an entire life cycle of supply and demand network that links the future market with securing clean hydrogen considering the geopolitical distribution. To this end, Korea also needs to expand bilateral cooperation countries by activity type, and it seems necessary to seek various geopolitical-based bilateral cooperation and support measures for developing countries to diversify the supply sources of hydrogen.

The government enforced policies such as social distancing and limiting business hours to prevent the spread of COVID-19. However, the impact of the long-term COVID-19 pandemic is causing more serious difficulties for small business owners. The government intended to relieve the business management pressure for small business owners by drawing up the COVID-19 emergency disaster relief funds. The funds provided temporary support for the small business owners, but the prolonged pandemic worsened the business management difficulties. Therefore, this study will apply fixes that fail and shifting the burden archetypes from the system archetype of system thinking for the exploratory deduction of policy measures as the policy leverage to effectively enhance the recovery of small business owners. In response to the situation, emergency financial aid for small business owners and support that can enhance the self-sustaining powers are required to heighten the recovery of small business owners.

Purpose: This study aims to explore the ways to improve the security of temporary shelters in case of nuclear power plant accidents. Method: In this study, we mainly rely on the case studies on previous nuclear power plant accidents-Chernobyl, Fukushima, and Three Mile Island (TMI) cases. Result: The current radiation emergency response plans for nuclear power plant accidents center around the evacuation procedure. As a result, the concept of "shelter in place" has been understood as a means of assisting resident evacuation. However, based on the case studies, we find that encouraging shelter in place, rather than simply emphasizing evacuation, would help minimize unnecessary casualties, especially in case of the accidents rated greater than or equal to INES 5. To facilitate better shelter in place, we recommend utilize apartments as temporary shelters and suggest some possible improvements to ensure those apartments could be equipped with technologies for high radiation protection. Conclusion: To ensure better shelter in place, we recommend using apartments as temporary shelters, and we seek to supplement the function of apartments by using shielding, positive pressure, and sealing technologies.

This study examines and identified a series of strategies of Russia's political elites to maintain and strengthen their dominance by reviewing the case of revisions in the election laws of Russia in 2014. At that time, a mixed-member electoral system was newly introduced, and on the surface, it seemed that the new system was a step toward meeting the demands of the people for "enhanced democracy". However, in 2016 and 2021, the ruling party of Russia won the general elections by making the most of the factors that could distort the election results inherent in the mixed-member electoral system. Therefore, this study aimed to analyze whether the revision of election laws was a mere vehicle used by the ruling party, United Russia, to maintain its political power, or whether it was a leap forward to achieve democracy. The study result indicate that the revision of election laws in 2014 was part of the policy responses to the internal conflicts in the circle of Russia's political elites, which had been rising since 2008, as well as to the public resistance. In other words, it was confirmed that the revision of election laws was one of the measures taken to "minimize competition" and "reproduce political power on a stable basis".

There is no internationally accepted codified definition of digital trade because of the wide variety and scope of related industries and transactions(product + service + data) in general. Recently, innovative changes are taking place in digital trade due to the development of technologies such as IT due to the 4th industrial revolution, and advanced countries such as the US, EU, and Japan are including digital trade issues such as data movement liberalization in the negotiation agenda of the digital trade agreement. The issue with the liberalization of cross-border data movement is that freedom of data movement is necessary to vitalize digital trade, but it also increases the risk of information security and privacy violations. Looking at the directions of advanced countries, the US favors minimization of regulations, Europe favors regional single marketization, but passively opens up to the outside world, and China promotes independent markets through regulations. Therefore, measures to strengthen restrictions on cross-border data movement are an issue that has recently been implemented by each country or an international aggrement is scheduled to be reached soon, and Korea also needs a close response.

Most of the existing Distributed Denial-of-Service mitigation schemes in Software-Defined Networking are only implemented in the network domain managed by a single controller. In fact, the zombies for attackers to launch large-scale DDoS attacks are actually not in the same network domain. Therefore, abnormal traffic of DDoS attack will affect multiple paths and network domains. A single defense method is difficult to deal with large-scale DDoS attacks. The cooperative defense of multiple domains becomes an important means to effectively solve cross-domain DDoS attacks. We propose an efficient multi-domain DDoS cooperative defense mechanism by integrating blockchain and SDN architecture. It includes attack traceability, inter-domain information sharing and attack mitigation. In order to reduce the length of the marking path and shorten the traceability time, we propose an AS-level packet traceability method called ASPM. We propose an information sharing method across multiple domains based on blockchain and smart contract. It effectively solves the impact of DDoS illegal traffic on multiple domains. According to the traceability results, we designed a DDoS attack mitigation method by replacing the ACL list with the IP address black/gray list. The experimental results show that our ASPM traceability method requires less data packets, high traceability precision and low overhead. And blockchain-based inter-domain sharing scheme has low cost, high scalability and high security. Attack mitigation measures can prevent illegal data flow in a timely and efficient manner.

Unlike other lawsuits, patent infringement litigation is a very difficult case to grasp without expert knowledge of the patented technology. The Patent Agent Act seems to recognize the legal representation of patent agent in Article 8, but the Constitutional Court and the Court have refused to recognize patent agent's legal representation right in the patent infringement suit. In this regard, constant controversy is taking place among patent agents and lawyers. This study examines the measures to enhance the effectiveness and professionalism of patent litigation in patent infringement litigation. This study analyzes the role of patent attorneys in patent infringement lawsuits in major countries and derive rational alternatives. As a result, it is inappropriate to restrict the attorneys' automatic acquisition of patent attorneys' qualifications or revise the patent attorneys' law in relation to the patent attorney's right of proxy. In the case of litigation parties, it is a desirable alternative to introduce a revised patent attorney system for the fundamental problem solving and to allow the litigants to reasonably choose the litigation agent.

The development of digital technology and the Internet has brought about a great change in the content industry. In order to keep pace with these changes, the copyright law has undergone several revisions, and the concept of "digital sound transmission" was introduced in the 2006 revision. However, in the current law, digital audio transmission is problematic in that the criteria for distinguishing between broadcasting and transmission is abstract and unclear. This ambiguity makes it difficult to judge the legal status of new music webcasting service such as "Free Litsen". Although these services are positioned as digital audion transmission, they have created a new concept of pseudo transmission because of its similarity to the audio transmission in its convenience and utility. These problems stem from the imbalance of between the development of technology and the legal system, so the change of the legal system is inevitable. Thus, this study discusses US copyright law and related cases, and then suggests solutions for pseudo transmission problems. This study suggests legislative criteria for pseudo transmission problems and legislative measures that can reduce the actual damage to the music market.

2022년 7월 8일 일본 전 총리 아베는 나라현의 야마토사이다이지 역에서 야마가미 데스야의 사제총격에 심각한 총상을 입고 과다출혈로 사망하였다. 다중이용시설에서의 테러안전관리 미흡으로 인해 발생한 본 사건은 다중이용시설 테러안전관리의 중요성을 보여주는 대표적인 테러사례이다. 국내와 유사한 테러환경을 갖춘 인접국가 일본 발생한 테러사건이므로, 국내 다중이용시설 테러안전관리에 대한 경각심을 일깨워 주고 있다. 대한민국은 세계적으로 높은 인구밀도와 원스톱 서비스의 선호 욕구로 인해 대부분의 다중이용시설들은 운송·판매·문화 및 집회 등의 기능이 다양하게 복합된 시설로 발전해 가고 있어, 테러리스트의 테러대상 선정의 3가지 요건인 접근성(Easy-Access), 상징성(symbolism), 미디어 집중성(Media Attention)을 갖춘 매력적인 테러대상시설이 되어 가고 있다. 또한, 최근 국제테러 동향을 살펴보면, 국가중요시설, 군사시설과 같은 하드 타겟(Hard Target)보다 엔터테인먼트, 문화, 관람, 카지노, 시장, 플라자, 광장, 소매점, 대형마트 등의 판매·문화 및 집회시설인 소프트 타겟(Soft Target)에서 고 위험성의 테러가 높은 빈도로 발생하고 있는 추세로 다중이용시설은 테러안전관리가 절대적으로 필요해져 가고 있다. 이에 반해, 국내 다중이용시설 테러안전관리를 위한 지도·점검 및 시설 취약요인 사전제거 활동 등 대부분의 대테러 활동이 미흡한 실정이다. 국내에서 소프트 타겟은 『테러방지법 제25조 시행령』(테러대상시설 및 테러이용수단 안전 대책 수립)과 『테러대상시설 및 테러이용수단 시설의 안전대책에 관한 규정』에 따라 정부에서는 대테러 활동을 매년 상시적으로 하고 있지만, 아직까지 부족한 실정이다. 따라서 본 연구에서는 현 다중이용시설의 테러안전관리 문제점과 취약점을 살펴보고, 이에 대한 개선방안을 제시하고자 하였다.

The increase in assertive and unilateral measures represents a key feature of the recent global trade environment. Against this backdrop, the EU is pushing to introduce the so-called "anti-coercion instrument(the instrument)," which aims to allow unilateral countermeasures in the event of economic coercion or threats from third countries. This paper examines the recent assertive trade environment and the legislative background of the instrument. It evaluated the necessity of and concerns arising from the instrument by comparing the existing EU trade policy, i.e., Trade Barrier Regulation (TBR). In addition, the paper aims to analyze the permissibility of the instrument under the WTO system, especially in the context of the principle of "strengthening of the multilateral system." Finally, the paper draws implications of the instrument in terms of our domestic policies that can effectively address economic threats or trade friction in the growing geopolitical crisis.
