Carbon neutrality is the concept of reducing greenhouse gases emitted by human activities and making actual emissions zero through removal of remaining gases. It is also called "Net-Zero" and "carbon zero". Korea has declared a "2050 Carbon Neutrality policy" to cope with the climate change crisis. Various carbon reduction legislative processes are underway. Since carbon neutrality requires changes in industrial technology, it is important to prepare a system for carbon zero. This paper aims to understand the status and trends of global carbon neutrality technology. Therefore, ROK's web platform "www.naver.com." was selected as the data collection scope. Korean online articles related to carbon neutrality were collected. Carbon neutrality technology trends were analyzed by future signal methodology and Word2Vec algorithm which is a neural network deep learning technology. As a result, technology advancement in the steel and petrochemical sectors, which are carbon over-release industries, was required. Investment feasibility in the electric vehicle sector and technology advancement were on the rise. It seems that the government's support for carbon neutrality and the creation of global technology infrastructure should be supported. In addition, it is urgent to cultivate human resources, and possible to confirm the need to prepare support policies for carbon neutrality.

국제사회는 1992년 기후변화협약 체결 이후 지구온도 상승을 2℃이하로 억제하는 등 기후변화 문제를 해결하기 위해 노력하고 있다. 그러나 1997년 선진국(38개국) 중심으로 2020년까지 탄소감축(교토의정서)을 선언하였음에도 불구하고, 미국, 중국 등의 감축의무 미참여로 인해 기후변화대응에 대한 한계를 노출한 바 있다. 그 이후 COP21(2015년)에서 모든 국가에 감축의무를 부여하는 신(新)기후체제를 출범함으로써 선진국뿐만 아니라 개발도상국도 2020년부터 탄소감축의무를 부담하게 되었다. 영국은 기후변화위원회의 권고에 따라 탄소중립경제(Net-Zero Economy) 실현을 위해 국가적 탄소배출 목표를 발표(2019년)하고 온실가스 배출 'Zero'를 기후변화법에 명시하여 모든 산업 인프라 및 환경에 적용시키려 한다. 전 세계에서 최초로 영국의 물산업 분야는 'Net Zero 2030 Routemap'을 발표하여 물산업분야의 탄소중립 실현을 위해 다양한 정책적 로드맵과 실행방안(시나리오)을 수립하였다. 이러한 실행방안은 국가정책에 부합하고 자국내 물기업의 탄소저감 실행계획의 수립을 지원하는데 그 목적이 있다. 구체적인 실행방안은 탄소중립 달성을 위해 비용, 효과, 기술수준 및 기간 등을 고려하여, ①수요주도형, ②기술주도형, ③자연친화주도형, 그리고 ④복합형으로 제시하고 있다. 실행시나리오에 따르면, 수요주도형은 상하수도 분야 수요관리 및 기술, 설비의 효율화를 통한 배출 저감 방안으로 2018~19년 기준, 총배출량 2.41MtCO2e에서 2030년까지 0.54MtCO2e으로 약 77%의 감소효과를 기대하고 있다. 기술주도형의 경우, 심각한 탄소배출 분야의 기술개발 및 혁신을 통해 배출량을 최소화하는 시나리오이며, 총배출량(2.41MtCO2e)을 0.10MtCO2e(약 96%)까지 감소시키기 위한 방안이다. 자연친화주도형은 물기업의 자산 및 그 외 지역에 자연친화적 환경조성을 통한 탄소상쇄방안을 중심으로 총배출량을 0.88MtCO2e(약 63%)까지 저감하는 효과를 나타낸다. 마지막으로 복합협은 시나리오별 실효성과 적용시기를 고려할 때 가장 효과적인 방안으로 약 74%의 저감효과를 나타내지만, 시기적절성, 효과성에서, 가장 최적의 방안으로 제시되고 있다. 본 연구는 이러한 영국 물산업 분야의 탄소중립 정책과 실행방안 분석하고 그 시사점을 제시함으로써 국내 물산업 분야의 탄소중립을 위한 구체적 실행계획 수립에 이바지하고자 한다. 물산업 분야의 탄소중립은 기존 물산업 가치사슬 변화 등 물산업 생태계 전반의 변화를 초래할 것이며, 이러한 변화는 국내 물산업의 자본·운영시장의 비용증가에 대한 도전과 신재생에너지 기술 등 탄소 중립 기술 습득 및 새로운 일자리 창출 등 신(新)시장체계에 대한 기회가 동시에 상존한다.

Interest in building underground spaces is increasing for the creation of downtown infrastructure and efficient space utilization. A representative method of utilizing underground space is a tunnel, and in addition to road tunnels, the construction of utility tunnels such as power conduits and utility conduits is gradually increasing. The current basic tunnel construction method can be divided into NATM (New Austrian Tunnelling Method) and TBM (Tunnel Boring Machine). The NATM is a reliable method, but it is accompanied by vibration and noise due to blasting. In the case of the TBM excavation method, there are disadvantages in terms of construction period and construction cost, but it is possible to improve economic feasibility by introducing appropriate complementary methods. In this study, a blasting method was develop using the NATM after TBM pre-excavation using the protective shield method. This is a method that compensates for the disadvantages of each tunnel construction method, and is expected to reduce construction costs, blasting vibration, and noise. In order to review the performance of the developed method, an experiment was conducted to evaluate the performance of explosion-proof tube to which a protective shield scale model was applied, and the impact of blasting vibration of the protective shield method was analyzed.

Autonomous vehicles use various local sensors such as camera, radar, and lidar to perceive the surrounding environment. However, it is difficult to predict the movement of vulnerable road users using only local sensors that are subject to limits in cognitive range. This is true especially when these users are blocked from view by obstacles. Hence, this paper developed an algorithm for collision avoidance with VRU using V2X information. The main purpose of this collision avoidance system is to overcome the limitations of the local sensors. The algorithm first evaluates the risk of collision, based on the current driving condition and the V2X information of the VRU. Subsequently, the algorithm takes one of four evasive actions; steering, braking, steering after braking, and braking after steering. A simulation was performed under various conditions. The results of the simulation confirmed that the algorithm could significantly improve the performance of the collision avoidance system while securing vehicle stability during evasive maneuvers.

Traditionally, Germany, a conservative welfare state, has pursued a male breadwinner model based on gender division of labor. For a long time, Germany tried to address low fertility through economic support centered on cash benefits, but it was not successful. In 2007, the German government began to shift the paradigm of family policy for work-life balance under the slogan of "A mix of time policy, income transfer, and infrastructure." When the issue of low birth rates emerged as a national concern in Germany, there was a growing social sentiment that not only the government but also private companies should contribute to increasing fertility by providing family-friendly personnel policies and working conditions. Private companies have been voluntarily improving family-friendly working conditions beyond legal obligations, aiming to secure personnel and prevent turnover. Germany's fertility rate is currently rising toward the European average level in 2023, which can be attributed to the government's work-life balance policies and the participation of private companies. In terms of improving work-life balance policies in Korea, it has been proposed to change the perception of the need for fathers to participate in child care, to make parental leave compulsory for men, to guarantee employment for women after childbirth, to expand child care facilities, and to revitalize family-friendly policies in companies.

With the advent of deep learning technology, which is represented by AlphaGo, artificial intelligence (A.I.) has quickly emerged as a key theme of digital transformation to secure competitive advantage for businesses. In order to understand the trends of A.I. based digital transformation, a clear comprehension of the A.I. business ecosystem should precede. Therefore, this study analyzed the A.I. business ecosystem from the multi-actor network perspective and identified the A.I. platform strategy type. Within internal three layers of A.I. business ecosystem (infrastructure & hardware, software & application, service & data layers), this study identified four types of A.I. platform strategy (Tech. vertical × Biz. horizontal, Tech. vertical × Biz. vertical, Tech. horizontal × Biz. horizontal, Tech. horizontal × Biz. vertical). Then, outside of A.I. platform, this study presented five actors (users, investors, policy makers, consortiums & innovators, CSOs/NGOs) and their roles to support sustainable A.I. business ecosystem in symbiosis with human. This study identified A.I. business ecosystem framework and platform strategy type. The roles of government and academia to create a sustainable A.I. business ecosystem were also suggested. These results will help to find proper strategy direction of A.I. business ecosystem and digital transformation.

Ths study aims to analyze the economic impact of smart city construction project and operation project on the regions. The study used case studies to analyze the economic impact of smart city construction projects such as Busan EDC and Sejong 5-1, and operation projects such as Jeonju and Daejeon smart city plans. The study used a regional input-output model as its analysis model. The data used for the analysis was the 2015 regional input-output table published by the Bank of Korea. The industry was reclassified from 83 mid-category industries into 8 industries. The analysis results are summarized as follows. First, the construction project of smart cities was found to have a spillover effect (production inducement effect) not only in Seoul and Gyeonggi Province, but also in the surrounding areas of the target regions such as Gyeongnam (Busan EDC) and Chungnam (Sejong 5-1). Second, smart city operation projects had the greatest impact (production, value-added and employment) on the target areas (Daejeon and Jeonju), but the proportion of economic impact in regions other than Seoul and Gyeonggi was low. Third, the ripple effect was more concentrated in the Seoul and Gyeonggi regions when the smart city operation project was promoted rather than the smart city construction project. This is due to the concentration of major smart city-related companies, industrial clusters, and research and development infrastructure in the Seoul and Gyeonggi regions.

Village-concentrated agricultural regional development projects that aim for increased profits are now being aimed at core agricultural and fishing areas. These agricultural and fishing stimulus projects aim to not only increase the net profit of local citizens but also improve their living conditions. As the industry itself has changed, local rural areas have also changed in various ways. One such aspect is the emergence of rural-urban complexes known as "rurban" areas. These naturally occurring rurban regions are created by a combination of complex urban infrastructure while maintaining the insulated rural communities that agricultural areas are usually so readily identified by. "Jeongeupsi Naejangsnagdong", the target of this research, also specifies the unaltered surrounding natural environment of rural areas while at the same time containing complex central living areas typically found in urban areas. This research suggests that the direction of residents' participation in community-level rurban projects could solve the problems found in existing top-down government development projects. This research also suggests rurban area activation plans to improve living conditions through analysis of both local rurban agricultural characteristics and citizen demands. In order to encourage citizen autonomy and self-governing attitudes, citizen-strengthening workshop programs are proposed, such as citizen workshops or pilot activities. This research was carried out by target area analysis, rudimentary planning, development direction setting, detailed project planning, and finally project processing. This procedure established three goals, which are walking environment improvement, community infrastructure establishment, and good living environment establishments, based on actual site research and citizen demands. This research suggests plans to activate community groups that were already established and reflect citizen needs as the main avenues for local businesses. This research is predicted to promote more active and successful growth through autonomy in stimulating these increasingly emerging rurban agricultural regions.

With entry into force of the Nagoya Protocol to promote the fair sharing of the benefits of accessing and utilizing genetic resources, much support has been given to research on the development of biomaterials and products using domestic natural resources. Conservation and resource-saving of native species became very important through Nagoya Protocol enactment. The trend of cosmetic industry has been shifing from use synthetic chemicals to natural biomaterials, due to the safety regulations on new materials, ban on animal experiments, and expansion of cosmeceuticals range. In addition, functional cosmetic range has been expanded from whitening, wrinkle improvement, and ultraviolet shielding, to hair loss, hair loss alleviation, acne relaxation, and moisturizing of atopic skin, thus causing the activation of research about field of efficacy evaluation on natural biomaterials and commercialization. Chungbuk province is fostering the bio industry as a key industry for regional economic growth. For this purpose, Osong Biotechnology Complex/Ochang Science Industrial Complex in middle area, Jecheon biovalley in northern region, and Chungju Enterprise city have been established, thus playing a pivotal role in Bio innovative cluster in Korea. In particular, it was established the osong cosmetics clinical research support center to develop the cosmetics industry in chungbuk, thereby supporting clinical trials, efficacy evaluations, overseas certification, and overseas market entry in order to advance into the global market. In addition, oriental plants such as astragalus propinquus, schisandra chinensis, eucommia, alpiniae oxyphyllae fructus and biancaea sappan are being actively studied as global cosmetic ingredients through the promotion of various national research and development projects using natural materials in chungbuk province. The chungbuk natural product industry is expected to grow further throughout cosmetics industry development in the future, as companies and research institutes are actively promoting the secure index of effective material in natural products and effective material commercialization.
