Stable operation of the dam and the river is directly related to the life and property of citizens, and hydrological observation data reliability is essential to the safety against disaster. Even though real-time data acquisition with high accuracy is needed for scientific and reliable water resources management, currently operating water gauges installed on the upper and down stream of dams or rivers are not easy to be calibrated or corrected on site to ensure higher reliability. K-water Institute has been operating an international accredited calibration laboratory for flows meters, rainfall and water gauges. Rainfall gauges are calibrated in the fixed standard room or on-site. However, due to the absence of on-site calibration procedure and system, on-site calibration for the water gauges are performed by an external agency. Therefore, a development of standard calibration procedure and system for on-site calibration of water gauges is needed to improve the reliability of observed hydrological data.

일반적으로 21세기에는 로봇이 기존의 인간이 가지고 있던 작업영역을 대처 할 거라고 말해지고 있으며 가까운 미래에 재난 현장, 인명구조, 지뢰제거, 정찰과 같은 위험작업 영역에 대해서 먼저 기존 인력을 대처할 수 있는 이러한 로봇의 필요성이 두각 되고 있다. 그러나 이러한 위험 작업 현장에서 운영이 가능한 로봇이 만들어지기 위해서는 일차적으로 일반적인 위험작업 지역인 계단과 같은 비 평탄 지형에 대한 이동 성능을 보장할 수 있는 로봇 이동 기술의 개발이 필요하다 일반적으로 이동형 로봇은 Wheel Type, Track Type 그리고 Walking Type으로 구분이 된다. 하지만 비평탄 지역에서 Wheel Type은 Track Type에 비해서 상대적인 주행성능이 떨어진다고 일반적으로 말해지고 있으며 또한 Walking Type은 제어방식이 복잡하고 제어부의 크기가 커서 앞의 두 방식에 비해 절대적으로 이동속도가 느리다는 단점을 가지고 있다.

The Enforcement Decree of the Framework Act on the Management of Disasters and Safety Article 3-2 specifies two 'disaster management supervision agencies' for responding to shipping disasters. These are the Korea Coast Guard, which is an on-scene disaster-responding and coordinating agency, and the Ministry of Ocean and Fisheries, which is a government department, thereby leading to possibilities for confusion. In the case of shipping disasters, where a personnel entitled full power to deal with shipping disasters is designated and his/her powers and duties are clearly made, relationship of leading and supporting agencies is made clear, and command system is simplified, an efficient response to shipping disasters is made possible. In the management of shipping disasters, all the disaster management processes, that is, prevention-preparedness-response-recovery, should be dealt with systematically and consistently. Notably, to swiftly and efficiently cope with a disastrous situation, the decision-making and command system must be simplified. The establishment of a command system and decision-making must be made independently, based on expertise. In the US, irrespective of the type of disasters, the FEMA plays a leading role and the USCG responds a response to maritime disasters by establishing the Incident Command System or Unified Command System that is an incident management system. In the UK, the MCA supervises an event and responds to it, and the SOSREP has full power to work with command and coordination independently. SOSREP, among others, is necessary to prevent an inefficient dealing of a shipping disaster owing to confrontation between participants. With reference to such leading States' practice, the Korean government should make a standardized and simplified response to maritime disasters. This study deals with a new maritime disaster responding system and provides an idea of the revision of the existing legal regime.
