부유식 라이다는 해상풍력단지 조성 시 필수적인 풍황관측의 새로운 패러다임을 제공하는 시스템이다. 시간과 비용을 절약하고 환경에 미치는 영향을 최소화하며 지역사회의 반발까지 줄일 수 있어 업계의 표준으로 떠오르고 있다. 하지만 부표의 동요에 의한 교란요인이 관측자료의 신뢰도에 영향을 미치므로 안정적인 플랫폼의 설계 및 검증이 매우 중요하다. 국내에서는 이 분야의 기술 진출이 늦어짐에 따라 다수의 외국계 장비업체들이 국내시장을 장악하고 있다. 우리나라 서해안은 조수간만의 차가 매우 큰 천해성 환경이기 때문에 강한 해류가 반복적으로 나타나고, 계절별로 다른 강한 에너지의 파도가 형성된다. 본 논문은 이와 같이 복합적인 환경 특성을 지닌 우리나라 해역에서 라이다 운영에 적합한 부표식에 대한 연구를 수행하였다. 본 논문에서는 가장 먼저 적용된 선박형 부표식의 최적화 설계 및 검증 사례를 소개하고, 향후 다양한 플랫폼 개발의 기반이 될 중요한 개념을 도출하고자 한다.

Background: Air pollutants have been reported to have harmful effects on human health. Busan is a vulnerable area in terms of air quality due to the installation of various industrial complexes, particularly the port industry. However there is limited research data on the ambient air quality of residential areas near ports and industrial complexes. Objectives: This study aimed to determine the quarterly levels of air pollutants near industrial complexes and ports and to identify trends and characteristics of air pollutant exceedances. Methods: Air measurements were conducted quarterly. The measured air pollutants included O₃, SO₂, CO, NO₂, PM₁₀, and PM_2.5. PM₁₀ and PM_2.5 were measured using BAM-1020 equipment, while O₃, SO₂, CO, and NO₂ were measured using AP-370 Series equipment. The quarterly concentration levels of air pollutants were determined, and the influence of precipitation and commuting hours on fine particulate matter was examined. Analysis of variance (ANOVA) was conducted to determine if there was significance between the concentrations of fine particulate matter during commuting hours and non-commuting hours. Results: The concentrations of air pollutants were generally higher in the first and second quarters. Furthermore, the concentrations of PM₁₀ and PM_2.5 tended to decrease continuously following consecutive rainfall, with concentrations at the end of rainfall periods lower than those observed at the beginning. The frequency of exceeding average concentrations of PM₁₀ and PM_2.5 was higher on weekdays. Moreover, the average concentrations of PM₁₀ and PM_2.5 during weekday commuting hours were higher compared to non-commuting hours. Conclusions: The concentrations of air pollutants in the survey area were found to be higher than the overall average in Busan. Based on this study, continuous air quality monitoring is necessary for residential areas near industrial complexes and ports. For further research, health biomonitoring of residents in these areas should be conducted to assess their exposure levels.
