디지털 기술의 발전에 따라 해상환경은 빠르게 변화할 것으로 예상된다. 자율운항선박의 경우 국내ㆍ외 많은 국가에서 기술개 발 중이며, 국제사회는 이를 운용하기 위한 논의도 시작되었다. 선박의 변화는 해상교통 환경의 변화를 야기하며, 육상지원시설에 대한 변화도 촉구한다. 본 연구는 항행지원시설의 사이버 보안 체계 개선을 위해 해상교통관제 인원의 사이버 보안 관리 인식을 분석하고자 한다. 이를 위해 해상교통관제 중심으로 사이버 보안 관리 현황을 살펴보고, 해상통관제 인원을 대상으로 설문조사를 실시하였다. 설문조 사 분석은 IPA 방법론을 활용했으며, 분석결과 보안담당 경험이 있는 인원과 경험 없는 인원의 사이버 보안에 대한 인식차이가 뚜렷하게 나타났다. 더불어 사이버 공격 탐지 및 차단 관련 기술적인 조치가 가장 우선적으로 시행되어야할 사항으로 나타났다. 본 연구 결과는 항 행지원시설에 대한 사이버 보안 관리 체계 개선을 위한 기초자료로 사용될 수 있다.

해상교통정보의 수집, 관리 및 공유를 개선하기 위해서는 해상교통정보 관련 기술 동향 파악 및 해상교통정보의 현황·문제점 분석이 우선되어야 한다. 따라서 본 연구에서는 먼저 해상교통정보의 국내외 기술 동향을 조사하였으며 국내 해상교통정보의 수집·관리· 공유에 대한 현황·문제점을 분석하여 정리하였다. 자료를 토대로 문제점을 분석한 결과 우선 수집단계의 문제점은 주로 LTE 통신권을 벗 어나는 원거리 RADAR·CCTV·카메라 영상정보 수집의 어려움으로 나타났으며 이로 인해 EEZ를 거쳐 영해로 진입하는 밀입국 선박 등의 조기 탐지가 어려운 것으로 나타났다. 그리고 관리단계의 문제점은 대부분 해상교통시스템이 자체 구축한 물리 저장 공간을 사용함으로 써 저장 공간의 유연성 부족으로 인해 편리한 축소·확대가 어렵고 시스템 장애 발생 시 대비책으로 시스템 이중화·백업 등이 힘든 상황이 다. 또한 공유단계의 문제점은 대부분 해상교통정보 공유시 주로 내부망을 사용하고 있는 현황상 운영기관 외부로의 정보 공유가 어려운 것으로 나타났으며 LRIT·SASS와 같이 정부 클라우드를 통해 정보 공유가 되고 있다고 하여도 정부 클라우드의 특성상 해양 빅데이터 등 을 효과적으로 활용할 수 있는 다양한 애플리케이션의 제공이 원활히 되고 있지 않은 상황이다. 이러한 문제점들을 개선하기 위해 우선 수집단계의 경우 무인기·위성 등 수집장비의 추가 구축을 제시함으로써 수집구역을 확장하였고 관리·공유단계는 각 해상교통시스템의 운 영 주체·정보 공개성을 고려한 민간 클라우드 도입 및 구축형태를 제시함으로써 클라우드 도입 시 전문성·보안성 향상을 기대하였다.

The purpose of this paper is to propose part management and standardization to reduce cost and increase compatibility of parts through standardization and standardization of parts to be applied to urban air mobility(UAM) systems, Personnel Air Vehicle(PAV), Vertical Take-Off and Landing (VTOL), and so on. In other words, parts used in the urban air transportation system must be verified from the initial design stage in accordance with the aviation standard, and a systematic management system for various parts must be established to secure stability and improve quality. Therefore, as a system similar to the aviation component management system, it should be thoroughly managed for urban aviation components.

PURPOSES : The purpose of this study is to analyze the improvement effect of the distributed arrangement of a vehicle base, which is a policy on maximizing the cost efficiency and timely/spatial effectiveness of special transportation system (STS) operation for improving the mobility of the elderly and disabled. METHODS: (1) The characteristics of the current distributed arrangement of an STS vehicle base in an urban area was analyzed. (2) The quantitative improvement effect was derived by analyzing the actual measurement of operation during STS distributed arrangement test operation in Namyangju city. RESULTS : (1) Cities with large area and populations, which have a distributed living zone in an urban area, have a higher distributed arrangement ratio than urbanized smaller cities. (2) Based on the effectiveness analysis of the STS distributed arrangement test operation, the total travel time and distance decreased. CONCLUSIONS : (1) For the STS distributed arrangement, parking spots, driver standby, and restrooms must be prepared. Facilitating STS as a public institution consignment makes it easier to secure a vehicle base and management by utilizing public facilities. (2) Implementing the STS distributed arrangement of vehicle base allows for efficient response to demand through effective management of vehicles, which eventually decreases travel time and distance. This decrease not only reduces management costs but also increases supply expansion without an increase in the number of vehicles.

PURPOSES : This study aims to create a pleasant environment by exploring ITS technology-based reduction measures to manage vehicles on the road, which are the main cause of traffic noise, while identifying the effects of traffic noise and various noise reduction measures. METHODS : A review of the literature identified the matters discussed mainly by reviewing the pre-examination and related statutes of traffic noise management measures at home and abroad. Furthermore, in the field investigation section, the variables affecting traffic noise (traffic volume, large vehicle mix rate, and driving speed) were investigated and the noise impact was analyzed using the three-dimensional (3D) noise prediction model (SounpdPLAN). RESULTS: The noise impact levels of the 3D noise prediction model were identified from various angles, such as horizontal and vertical, and traffic noise management measures for pre-real-time management and related DB utilization measures were proposed. CONCLUSIONS: Unlike the existing traffic noise management measures, which focus on follow-up management measures, it is believed that further research is needed to develop standards and related guidelines that meet regional characteristics by taking into account the characteristics of traffic noise and creating concrete and drawing action plans that can be used in future policies using ITS technology.

This study investigated the indoor air quality conditions of public transportation according to the changing of seasons and different times of the day. We measured the concentration of PM10 and CO2, which are substances subject to control measures and limits established by Ministry of Environment for public transportation, and compared actual levels whit the legal standard. Public transportation was classified as subway lines (form 1 to 4), trains (KTX, ITX) and buses. The PM10 concentration was measured as being high during peak hours in winter compared to that in summer. On the other hand, the PM10 concentration in trains and buses was shown to be low. The CO2 concentration in public transportation was recorded as being higher than the legal standard. PM10 concentration was affected by the inflow of outdoor air, and CO2 concentration was influenced by the number of people in a particular space or environment. This survey focused on the indoor air quality of public transportation. The basic data could prove useful in formulating policies to promote and maintain good indoor air quality with regard to public transportation.
