A variety of decarbonized energy sources are being developed globally to realize carbon neutrality (Net Zero) by 2050 as a measure to address the global climate crisis. As the Korean government has also established a Renewable Energy 3020 policy and promoted energy development plans using solar or wind power, large-scale offshore development projects not present before in coastal waters, such as offshore wind farms, are being promoted. From ships' point of view, offshore facilities present obstacles to safe navigation, and with the installation of marine facilities, ship collisions or contact accidents between ships and marine facilities may occur in the narrowed water areas. In addition, there are concerns about environmental pollution and human casualties caused by marine accidents. Accordingly, we review overseas and domestic offshore wind farm development plans, analyze whether institutional devices are in place to ensure the safe passage of ships in wind farm areas, and study the safe operation of large-scale offshore wind farms and safe passage of ships along the Korean coast by comparing overseas legislative cases with domestic laws and presenting a proposal to illuminate the legal blind sectors.

A Basic Plan for the Promotion of Space Development (hereinafter referred to as "basic plan"), which prescribes mid- and long-term policy objectives and basic direction-setting on space development every five years, is one of the matters to be deliberated by the National Space Committee. Confirmed February 2018 by the Committee, the 3rd Basic Plan has a unique matter, compared to the 2nd Basic Plan. It is to construct "Korean Positioning System(KPS)". Almost every country in the world including Korea has been relying on GPS. On the occasion of the shooting down of a Korean Air flight 007 by Soviet Russia, GPS Standard Positioning Service has been open to the world. Due to technical errors of GPS or conflict of interests between countries in international relations, however, the above Service can be interrupted at any time. Such cessation might bring extensive damage to the social, economic and security domains of every country. This is why some countries has been constructing an independent global or regional satellite navigation system: EU(Galileo), Russia(Glonass), India(NaVic), Japan(QZSS), and China(Beidou). So does South Korea. Once KPS is built, it is expected to make use of the system in various areas such as transportation, aviation, disaster, construction, defense, ocean, distribution, telecommunication, etc. For this, a pan-governmental governance is needed to be established. And this governance must be based on the law. Korea is richly experienced in developing and operating individually satellite itself, but it has little experience in the simultaneous development and operation of the satellites, ground, and users systems, such as KPS. Therefore we need to review overseas cases, in order to minimize trial and error. U.S. GPS is a classic example.

The Korean government proposed the K-SDGs in 2019 to promote the UN SDGs, but the role and tasks of science and technology, an important means of implementing the SDGs, have not been materialized. Accordingly, the role of science and technology ODA for the SDGs was established through the Ministry of Science and ICT's policy research project 'Science and Technology ODA Promotion Roadmap for Spreading the New Southern Policy and Realizing the 2030 SDGs'. In addition, goals, strategies, and core tasks for the next 10 years were derived in 10 fields such as water, climate change, energy, and ICT. In this paper, we analyze 30 key tasks of the ODA promotion roadmap for science and technology for the realization of SDGs, and propose mid- and short-term tasks and implementation plans for effective roadmap promotion. Among the key tasks in each field, four common elements were derived: ICT/smartization, a global problem-solving center, cooperation/communication platform, and business model/startup support platform/living lab that can create and integrate roadmap implementation conditions. In addition, the four mid- and short-term tasks, 1) Establishment of science and technology ODA network, 2) Establishment of living lab business platform linked to start-up support business, 3) Local smartization of recipient countries, and 4) Expand and secure sustainability of global problem-solving centers, were set in relation to the implementation of the detailed roadmap. For the derived mid- and short-term tasks, detailed implementation plans based on the ICTization of global problem-solving centers were presented. The implementation of the mid- and short-term tasks presented in this paper can contribute to the more effective achievement of the science and technology ODA roadmap, and it is expected that Korea's implementation of SDGs will also achieve high performance.

Remarkable scientific and technological achievements are mainly shown in the 'super-convergence' or 'convergence of convergence' among cross- disciplinary fields, and advanced countries are promoting the 'high-risk, high-return research' ecosystem. Google LLC is carrying out numerous new challenges in terms of a non-failure perspective. Innovative research by the US Defense Advanced Research Projects Agency (DARPA) has produced such breakthroughs as the Internet, GPS, semiconductors, the computer mouse, autonomous vehicles, and drones. China is pioneering a 'Moon Village' and planning the world's largest nuclear fusion energy and ultra-large particle accelerator project. Japan has also launched 'the moonshot technology development research system' to promote disruptive innovation. In Korea, the government is preparing a new research program to tackle the global scientific challenges. Therefore, it is necessary to determine the reasonable geoscientific challenges to be addressed and to conduct a preliminary study on these topics. For this purpose, it is necessary to conduct long-term creative research projects centered on young researchers, select outstanding principal investigators, extract innovative topics without prior research or reference, simplify research proposal procedures, innovate the selection solely based on key ideas, and evaluate results by collective intelligence in the form of conferences.

녹색성장은 최근 세계적인 이슈가 되고 있다. 세계물위원회(World Water Council, WWC)의 경우 2012년 마르세유에서 개최되는 제6차 세계물포럼(World Water Forum, WWF)에서 물문제 해결을 위한 신개념 패러다임으로서 '녹색성장(Green Growth)'을 채택하기 위한 협력방안의 필요성을 제안하고 있다. 우리나라에서는 이미 녹색성장을 국가 슬로건으로 선정하고 글로벌 녹색성장연구소(Global Green Growth, GGGI)를 설립하는 등 녹색성장을 선도하고 있다. 이는 물의 중요성에 비추어볼 때 녹색성장을 물 분야에 확산시킬 수 있는 적절한 기회로 보인다. 녹색성장은 물 관련 환경서비스가 환경오염 없는 경제성장을 이룩하는 데 주요한 역할을 수행할 수 있다는 가능성과 당위성에서 파생된 최근에 만들어진 개념으로서, 물 분야의 경우 녹색경제에 있어서 중요한 역할을 수행해왔으며 이후 지속적인 인구증가, 물 소비패턴의 변화, 에너지비용 증가, 기후 변화 등으로 물 분야의 중요성은 더욱 커질 것으로 기대된다. 이처럼 물 관리는 경제발전, 재해로부터 보호, 인간의 건강 및 생태계와 삶의 질을 위하여 필수적이기에 녹색성장에 있어 중요한 역할을 수행하고 있다. 하지만 올바른 물 관리가 녹색성장에 기여할 수 있는 방법에 대해서는 아직 명확화 구체화되지 못하고 있는 실정이다. 이에 따라 녹색성장을 새로운 국가 성장 동력의 패러다임으로 구축하기 위해 수자원분야에서의 녹색성장방법론을 정립하고, 선진국과 개도국 정부들의 균형 있는 참여를 통한 글로벌 파트너십 구축이 요구되고 있으며, 이를 세계물위원회 등 국제기구와 공동으로 연계시킨다면 상당한 시너지 효과가 기대된다. 물관리는 국가의 경제발전, 재해로부터 생명과 재산의 보호, 인간의 건강 및 생태계 다양성 및 건전성 유지와 삶의 질을 향상을 위하여 매우 중요하며, 환경보존과 경제성장을 동시에 추구하는 녹색성장을 실현하는 데 있어서도 가장 핵심적인 사항이라고 할 수 있다. 그러나 올바른 물 관리가 녹색성장에 기여할 수 있는 방법에 대해서는 아직 명확하고 구체화 되지 못하고 있는 실정이다. 따라서 본 연구에서는 '물과 녹색성장'의 이론적 배경, 필요성, 개념정립, 벤치마킹 사례, 국제사회에서의 녹색성장과 관련한 논의 기구 및 흐름 등의 이해를 기초로 녹색성장을 통한 경제성장의 상호작용과 선순환구조를 체계화시키기 위한 균형방안을 제시하고자 한다. 또한 수자원 및 하천관리 분야에서의 WGG구현을 위한 정책제안 및 실행방안이 담긴 중장기 로드맵을 구축하여 물을 통한 성장의 발판을 마련하고자 한다.

Ranging is divided into a synchronous scheme and an asynchronous scheme according to the presence of global synchronization between nodes. In general, the asynchronous ranging is preferred over synchronous ranging because it does not require an expensive high-precision oscillator for the global synchronization. On the other hand, in a conventional asynchronous ranging scheme, the packets, which are generated by all nodes in a positioning system of a large-scale infrastructure and need to be sent for localization by reference nodes, are considerable, which cause an increase in network traffic as the number of nodes increases. The traffic congestion lowers the throughput of the network leading to a considerable loss of energy. To solve this problem, this paper proposes a ranging scheme, in which virtual transmission slots randomly and discretely selected by a plurality of nodes are used to reduce the overheads needed in synchronizing the nodes, and the ranging is performed asynchronously based on the virtual transmission slots, thereby decreasing the network traffic. In addition, a performance test proved that the proposed ranging scheme was stronger than the TWR and SDS-TWR on an error range, even though the intensity of traffic was very low.

Recently, United Nations found that 38% of global carbon emissions are generated in the building sector, surpassing other industries (32%) and transportation (23%), and ESG is actively used as a way to reduce carbon emissions in the building sector, led by overseas advanced countries. In Korea, as the National Pension Service announced "Consider ESG with more than 50% of investment assets" this year, the move to introduce ESG in the building sector is accelerating, centering on construction companies and asset management companies. However, as the domestic ESG evaluation system is still mainly focused on corporate governance and social responsibility, interest in the environmental sector is lagging behind that of advanced countries. As ESG in the building sector is expected to grow rapidly over the next 10 years, I would like to suggest the following development directions. The first is the expansion of the incentive system. In order for the government to successfully implement policies related to ESG in the building sector, incentive system such as tax reduction and building standards should be expanded further than now in addition to negative systems such as rent restrictions and punishment taxes due to regulatory violations. Second, standardized ESG standards are established. Rather than creating an independent Korean ESG standard that is far from global standards, it is necessary to organize the common parts of global standards and evaluation methods and create and provide guidelines in the form of standard textbooks that can be used equally by all stakeholders. Third, it is an effort to link ESG in the building sector with Digital Transformation(DX). This is because actual energy savings and carbon emission reduction can be realized only when the operation method of the building sector, which is operated mainly by manpower, is digitalized and converted to an intelligent way.

This paper analyzed SCOAP3 journals, which have been evaluated as successful open access models, to understand the characteristics of scholarly communication among domestic researchers in the field of high energy physics (HEP). As research methods, a quantitative analysis using statistics and a network analysis of authors' affiliated institutions and academic journals were conducted to understand collaboration and research activities of domestic researchers in the HEP field. The results of the study revealed that, among the 10 SCOAP3 journals in which Korean researchers participated, the proportion of articles in which Korean authors participated was 8.0% of the total. The proportion of papers with more than 1,000 co-authors per paper was 28.7% of the total. The results of this analysis proved that Korean researchers were actively collaborating in the HEP global network. From the results of the network analysis to understand the cooperative relationship centered on the affiliated organization, the cooperative network could be divided into three clusters: a cluster centered on S universities, a cluster centered on K research institutes that provided researchers a cooperative infrastructure with CERN, and a cluster centered on I research institute. Through the network analysis for research institutes and journals, it was found that JHEP, PRD, and PLB among academic journals were highly participating journals, and universities and researchers were also participating in the writing of open access papers. The results of this study can be used as a basic resource for understanding researchers and building a research information environment in libraries.

In this study, the effect of repeated traffic vibration on the long-term stability of mine openings is analyzed for re-utilization of abandoned mine galleries. The research mine in this study is an underground limestone mine which is developed by room-and-pillar mining method, and a dynamic numerical analysis is performed assuming that the research mine will be utilized as a logistics warehouse. The actual traffic vibration generated by the mining vehicles is measured directly, and its waveform is used as input data for dynamic numerical analysis, As a results of dynamic numerical analysis, after 20,000 repetitions of traffic vibration, the mine openings is analyzed to be stable, but an increase in the maximum principal stress and an additional area of plastic zone are observed in the analysis section. As shown in the changes of displacement, volumetric strain, and maximum principal stress which are measured at the mine opening walls. It is confirmed that if the repeated traffic vibration is continuously applied, the instability of the mine openings can be increased. Authors expect that the results of this study can be used as a reference for basic study on utilization of abandoned mine.
