The Korean government announced its goal of commercializing autonomous vehicle by year 2020. With such changes, it is expecting to decrease car accident mortality by half. To commercialize autonomous car, not only worries on safety of autonomous vehicle has to be solved but at the same time, institutional system has to be clear to distinguish legal responsibilities in case of accident. This paper will present the legal improvement direction of the introduction of autonomous vehicles as follows. First, it is necessary to re-establish concept of 'driver' institutionally. Second, it is appropriate to focus on Level 3 autonomous vehicle which is about to be commercialized in year 2020 and organize legal responsibility. Third, we should have a clear understanding on how level 3 autonomous vehicle will be commercialized in the future. Fourth, it is necessary to revise The Traffic Law, Act on Special Cases concerning the Settlement of Traffic Accident, and Automobile Accident Compensation Security Law in line with level 3 autonomous vehicle. Fifth, it is necessary to review present car insurance system. Sixth, present Product Liability Law is limited to movable products (Article 2), however, it is necessary to include intangible product which is software. Seventh, we should review on making special law related to autonomous car including civil, criminal, administrative, and insurance perspectives.

This study revises current feasibility evaluation guideline for agricultural infrastructure improvement project considering recent changes in social and economic environment in rural area. We use an AHP(Analytic Hierarchy Process) approach to consider qualitative evaluation items in policy enforcement and balanced regional development as well as quantitative items in current economic analysis in the process of feasibility evaluation and decision making. The criteria system is composed of three level hierarchy. In the first level which consists of economic analysis, policy analysis, and regional development analysis, economic analysis was ranked top with relative weight of 0.45 and regional development analysis the lowest with 0.22. In the second level which consists of three evaluation items under policy analysis, consistency in policy enforcement, risk factors, and special evaluation factors, consistency in policy enforcement was ranked top. Finally, 13 detailed evaluation items in the third level were surveyed and ranked by using a comprehensive criticality vector. The result shows that the three most important evaluation items are 'degree of underdevelopment', 'spill-over effect of regional economy' and 'consistency with related planning and policy direction'.

This study aims for improving the system in Disaster Management of Local Government. In addition, the overall disaster management system was compared to the effectiveness of the disaster prevention system and reliability, and problems and improvement points were derived. The disaster management system in Korea has a structure that promptly investigates and restores damage by a simple procedure. Korea disaster management system manages information on top-down structural disasters through the flow of prevention, preparation, response, and recovery. The process from disaster response to recovery under the leadership of the central disaster safety headquarters is simplified. Disaster management tasks are dispersed among departments, making it difficult to respond promptly. Under the control of the central government, disaster management, such as disaster prevention, investigation, and recovery, are carried out. The disaster management improvement direction of the local government should establish the disaster response system focusing on the local government. Therefore, it is necessary to have budget to operate the organization - centered disaster management budget and the disaster management organization. The disaster response manual should be prepared considering the disaster environment and disaster prevention plan. In order to utilize disaster information, it is necessary to reorganize information system such as integrate and streamline of the private resource database and NDMS.

G-SEED's evaluation of existing buildings is an important point because the energy consumption and CO2 emissions of existing buildings are continuously increasing due to the aging of buildings over time. However, as G-SEED certification is concentrated on new buildings and the standards are not yet available, we will make improvements to evaluate the existing buildings of G-SEED. In order to improve G-SEED for EB, two research procedures were carried out. First, LEED EBOM and LEED for NC compare and analyze evaluation items and methods, and LEED EBOM focuses on evaluation of existing buildings. Second, we analyzed the certification evaluation contents of eight domestic LEED EBOM accredited buildings and obtained items that can be applied or need to be applied when revising G-SEED for EB. LEED EBOM is focused on improving the performance and utilization of data that track and manage the energy and environmental effects of building operations. As a result of the case analysis, the evaluation of G-SEED for EB requires quantitative evaluation items such as environmental management of buildings, energy performance status of building, improvement plan and improvement of performance according to tracking value. Although G-SEED for EB is not structured yet and there are few cases of certification, it is expected that quantitative evaluation of existing buildings will be made through continuous research.

정수처리공정에서 안정적인 탁도 관리가 날이 갈수록 중요해지고 있다. 따라서 침전 효율 향상을 위한 플록형성 공정의 최적화는 매우 중요하다. 우리는 전산유체역학적 방법을 이용하여 플록큐레이터의 회전방향(시계방향, 반시계방향)에 따른 플록 형성지 내 유동특성을 평가하였다. 평가 결과, 플록큐레이터가 시계방향으로 회전하는 경우는 플록큐레이터 회전방향과 수류 흐름이 일치하는 수표면 쪽에서 유동이 강해지고 유출량의 분산 및 표준편차는 각각 8.5, 2.9로 나타났다. 반면에 플록큐레이터가 반시계 방향으로 회전하는 경우는 플록큐레이터 회전방향과 수류 흐름이 일치하는 바닥 쪽에서 유동이 강해지고 유출량의 분산 및 표준편차는 각각 5.3, 2.3으로 나타났다. 또한 플록형성지 유출량은 1,2단 플록큐레이터 회전방향보다는 3단 플록큐레이터의 회전방향에 의해 주로 영향을 받으며 3단 플록큐레이터가 반시계방향으로 회전하는 경우가 시계방향으로 회전하는 경우보다 유출량의 편차가 적기 때문에 침전지의 균등한 흐름을 위해 유리하다.

음원의 음량, 방향 및 음원까지의 거리와 같은 음원의 특성을 인식하는 것은 자율주행차, 로봇 시스템, AI 스피커 등 무인 시스템에서 중요한 기술 중의 하나이다. 음원의 방향이나 거리를 인식하는 방법은 레이다, 라이더, 초음파 및 고주파와 소리를 이용하는 방법이 있다. 그러나 이러한 방법은 신호를 발신하여야 하며, 장애물에 의한 비가시 영역에서 발생하는 음원은 정확하게 인식할 수 없다. 본 논문에서는 비가시 영역을 포함한 주변에서 발생하는 음원의 음량, 방향 및 음원까지의 거리를 인식하는 방법으로 가청 주파수 대역의 소리를 검출하여 인식하는 방법을 구현하고 평가하였다. 음원을 인식하기 위하여 주로 사용하는 교차형 기반의 음원인식 알고리즘은 음원의 음량과 방향을 인식할 수 있으나 사각영역이 발생하는 문제가 있다. 뿐만아니라 이 알고리즘은 음원까지의 거리를 인식할 수 없다는 제약이 있다. 이러한 기존 방법의 한계를 탈피하기 위하여, 본 논문에서는 교차형 기반의 알고리즘보다 더 발전된 직사각형 기법을 사용한 QRAS 기반의 알고리즘으로 음원의 음량, 방향 및 음원까지의 거리를 인식하여 음원의 특성을 파악할 수 있는 음원인식 알고리즘을 제안한다. 전방향 음원인식을 위한 QRAS 기반의 알고리즘은 직사각형으로 배치된 4개의 음향센서에 의하여 도출되는 6쌍의 음향 도착 시간차를 사용한다. QRAS 기반의 알고리즘은 기존 교차형 기반의 알고리즘으로 음원을 인식할 때 발생하는 사각영역과 같은 문제점을 해결할 수 있으며, 음원까지의 거리도 인식할 수 있다. 실험을 통하여 제안된 전방향 음원 인식을 위한 QRAS 기반의 알고리즘은 사각영역없이 음원의 음량, 방향 및 음원까지의 거리를 인식할 수 있음을 확인하였다.
