This paper examines the historical meaning and value of sound art curating as a key type of interdisciplinary and convergence art practice that has been unfolding since the mid-20th century. Accordingly, this paper summarizes the developmental process from the beginning of 'sound art' to the present, but examines the context of visual art in which the material 'sound' functioned in chronological order, and focuses on curating cases of major sound art exhibitions. The purpose of this study is to analyze the impact and contemporary significance of the provided aesthetic experience. To this end, the text is divided into three sections and developed. The first section recognizes that the late 19th century futurist and Dadaist sound poetry, followed by Marcel Duchamp's 1913 attempt to combine musical score with visual art, had a profound influence on the visual music of avant-garde composer John Cage. This explains why this background caused the emergence of exhibitions dealing with 'sound' as a new medium. The second section explains that in the 1970s, sound as an artistic medium played a role in reflecting the critical relationship with the exhibition space dominated by visuality. In the third section, we analyze the curatorial methodology that allows the audience to experience sound as if it were a visual object within the organization of the exhibition hall from the 1980s to the present. Through this process, this paper critically treats the historical practice of customizing the perceptual structure in the exhibition hall, and considers the meaningful methodology of sound art curating considering the role of sound full of vitality in the contemporary art scene.

This paper intends to focus on the practical activities and historical significance of network art, that is, 'net art' as an artistic form that depends on network technology. This is because the appearance of net art, which constructs a new interactive art that cooperates and exchanges with each other beyond the boundaries of time and space, can be a contemporary alternative in overcoming the limitations of traditional art. Another important research area to be considered in this paper is net art curating, as well as considering the significance of net art in art history. As new media art that is defined as a 'process' rather than a complete object, net art is a digital art that requires functions such as aesthetic appropriation, dissemination, and mediation performed online, unlike physical presentations with high perfection in exhibition halls. It is accompanied by a new social and cultural curatorial. This appearance requires both artists and curators to reorganize the strategy that net art curating in technoculture should have. Therefore, this paper attempts to question the creative strategies of net art in the wave of globalization in the 21st century, and to examine the artistic meaning and critical value of the experimental net art curatorial method that emerged through the realm of new technology and media. For this purpose, this paper demonstrated key examples of net art works and exhibition projects that started with Fluxus in the 1960s and are spreading all over the world in the 2000s.

In this study, radiation exposure doses were measured in the course of clinical practice of radiation workers, radiological technologists in the radiation-related worker group, and preliminary-radiological technologists who were classified as frequent visitors. Radiological technologists who worked in the radiation area of C University Hospital in Incheon for a year from January 2021 and 121 students who completed clinical practice at the same medical institution from July 1 to August 31 were the subjects of the study. The nominal risk factor based on ICRP 103 was used to evaluate the probability of side effects due to the exposure dose to the lungs, which are organs at risk of damage due to radiation exposure dose. During the clinical practice period, radiology students, who were classified as frequent visitors, had a surface dose of 0.98 ± 0.14 mSv and a deep dose of 0.93 ± 0.14 mSv. In other words, 6.7 per 1,000,000 for shallow dose and 6.4 per 1,000,000 for deep dose were found to have side effects due to exposure to the lungs. This is a value in terms of exposure dose in one year. Considering that the radiation (science) education course is 3 or 4 years, systematic management and attention to prospective radiation workers who are going to clinical practice are required, and the stochastic effect of radiation In relation to this, it is considered that it will be used as basic data for radiation safety management.

In the Northeast Asian region, including Korea, China, and Japan, with rapid economic growth since the 1990s, intra-regional oil logistics has been increasing. Under such external circumstances, Korea has been pursuing a policy to become a Northeast Asian petroleum logistics hub since the mid-2000s. In order to become a Northeast Asian logistics hub, it is important to establish and promote a business model to promote the value-added oil logistics business. This study aims to propose policies and practical implications for increasing petroleum logistics by analyzing Korea's petroleum logistics business model in Northeast Asia. The results of case analysis through interviews with 23 tank terminal companies are as follows. First, most of the oil storage tank terminal companies interviewed are conducting value-added petroleum logistics such as blending, breaking bulk, and consolidation etc. Second, value-added petroleum logistics is caused by an imbalance in supply and demand among neighboring countries in Northeast Asia. In particular, there is a high demand for breaking bulk and blending connecting Japan, Oceania, the United States, and South America. Third, it is necessary to promote the promotion of value-added logistics by improving infrastructure, institutions, and regulations in response to the demand for value-added petroleum logistics, which will greatly contribute to Korea's policy for being Northeast Asian oil hub.

2020년 기준 국내 상수도 보급률은 99.1% 차지하고 있으며(환경부, 2019), 수도관리차원에서 수돗물은 먹는 물로 시판되어질 만큼 우수한 관리체계를 유지하고 있다. 그 반면에 지하수는 생활용수, 식품가공, 농·축산, 양어, 군부대를 비롯한 전국지역에서 연간 10억 8천만톤 용수를 소비하고 있음에도 (환겨례 신문, 2013; 환경부, 2019) 사용되는 지하수의 약 65%가 음용수 불가판정을 받았으며, 최근 지하수의 오염비율은 급격히 증가하는 추세이다. 특히, 지하수관정의 관리부주의에 의한 수질오염 및 수인성 다제내성균(슈퍼박테리아) 등에 의한 오염사례가 국내는 물론, 국제적으로 다수 보고되고 있는 실정이다 (환경부, 2013). 현재 지하수 수질관리는 공공기관 및 지자체 지정기관을 통해 진행되고 있으며, 검사기간은 수질채취로부터 통상 7~15일정도 소요되어 수질 관리 및 기준, 검사주기에 대한 애로가 많다. 현장 지하수관정에서 실시간 수질을 모니터링하고 이에 연동된 자동 수처리 시스템의 개발 및 도입은 나날이 심각해지는 환경오염 상황에서 선제적 예방과 해결방법으로 중요한 요소기술이다. 현재 지하수오염 및 부적합 음용의 수질처리는 화학약품, 필터여과, UV살균, O₃ (플라즈마)을 이용하는 것이 대표적이나, 화학약품의 경우 2차 오염이나 식품 세척 및 가공에 있어 부적합성의 한계점이 있다. 필터여과의 대표적인 RO필터의 경우 약 50% 순손실이 발생하고, UV 살균의 경우 UV에 의한 사용관리자의 위험 및 장비의 광부식 문제, O₃ 의 경우 고압전류 사용에 따른 위험성 등의 한계점이 나타나고 있다. 지하수 수질정화를 위한 광유도 활성산소(¹O₂, ·O^-₂)는 광감응제에 가시광의 빛 조사를 통해 생성되는 활성산소로의 에너지 및 전자 전이가 동시 진행되어 단일항 산소(¹O₂)와 슈퍼옥사이드 이온(·O^-₂)을 생성하게 된다. 생성된 활성산소는 유해미생물 또는 유기화학물과 개열, 제거, 치환 반응 등을 통해 미생물사멸 및 유해화학물질들이 분해 가능하다. 이를 이용한 지하수 유해미생물 사멸기술, 장비, 실시간 지하수의 분석기술 및 정수처리, 지하수 물순환 시스템 개발뿐만 아니라 지하수 음용수 및 오염개선, 지하수 기저유출에 의한 오염원 저감으로부터 지류·지천, 하천 본류 수질개선 등의 대상지역에 활용 가능하다. 또한 광유도 활성산소는 기존 상수도 수처리에 있어 오존(O₃) 처리와 이산화티탄을 이용한 AOP과정을 단일처리 공정으로, 기존 O₃ 의 특성상 확산 거리가 매우 길어 사람을 포함한 생체 내에 유입 시 다양한 부작용 발생과 O₃ 차폐시설 요구의 문제점 극복의 대안으로 환경 및 인체에 무해한 광유도 활성산소 시스템을 적극적으로 도입 및 적용해야 한다. 본 연구 목적은 정류상태 흡광분광기술을 이용한 실시간 수질 모니터링과 광유도 활성산소를 이용한 유해 미생물의 멸균효능 및 지하수 수질관리 기술로의 적용 가능성을 제시하고자 한다.

Recently, the increase of international trade volume is leading to risk exposure and safety accidents in the port terminal industry. In addition, as Serious Disaster Punishment Act came into effect on January, 2021, various guidelines and laws to protect safety and life in port terminals are being enacted. However, despite these efforts, medium-to-large safety accidents in the port terminal industry have occurred. According to the Korea Occupational Safety and Health Agency, from 2016 to 2019, the number of casualties in the port handling industry increased by 4.2%. To build some effective follow-up management of port accidents and preparation of related safety laws/systems, a risk analysis in consideration of causes and damage of accidents should be conducted. Therefore, in this study, major risk factors and preventive measures were derived by conducting risk assessment based on 1,039 cases of port terminal accidents collected by the Korea Occupational Safety and Health Agency for five years. Priorities for preventive measures were then determined through IPA analysis, Borich needs analysis, and The Locus For Focus analysis.

The recent increase in international trade volume and explosive increase in cargo volume due to the non-face-to-face society are leading to an increase in risk exposure and safety accidents in the port logistics industry. Consequently, as the atmosphere and consensus on safety are spreading throughout the society, various safety laws are being enacted by the industry. Nevertheless, according to the industrial accidents status analysis by the Ministry of Employment and Labor, the average annual number of injured persons increased by 11.1% and the number of deaths by 4.0% from 2015 to 2019. This means that special attention should be paid to possible future risks and preventive measures for major causes of accidents should be established. Therefore, in this study, risk assessment was conducted based on 5,028 accident cases that were reported by the Korea Occupational Safety and Health Agency for 5 years, from 2016 to 2020, and major risk factors for each industry were derived, and then bow-tie analysis was conducted to perform the risk assessment; Further, the study aimed to derive the causes and preventive measures from the risk factors.
