일반적으로 인간은 외부로부터 정보의 85% 이상을 '시각'을 통해 얻고 있으며 색(色)-형(形)-Texture(質感)의 순으로 사물을 인식한다. 그래서 인간은 예전부터 위험상황에 대응하기 위해 대상의 정보를 신속하게 전달하는 수단으로 색채를 활용해 왔으며, 안전색채는 이러한 색의 속성을 이용 위험으로부터 안전을 확보하기 위해 적용되어왔다. 현재 안전에 관한 정보를 제공하는 시스템에는 언어나 문자사용을 가능한 한 사용하지 않고 안전표지를 국제적으로 표준화하여 사용하는 것이 바람직하며 실제로 국제표준기구(ISO)가 제정한 '안전색채 및 안전표지(ISO3864)'를 채택하거나 자국의 실정에 맞춰 일부 변경 사용하고 있다. 또한 안전표지는 색만이 아니고 그것을 표시하는 형까지 포함 사용되며 형태는 표시 물건에 따라 다양하며 또한 색채가 일으키는 심리 작용을 이용하여 주의를 환기하거나 위험을 경고하며 위험방지 및 긴급사태에 대한 대응을 목적으로 하고 있다. 안전색채 및 안전표지의 목적은 안전 및 건강에 영향을 미치는 대상물 및 장소에 신속하게 주의를 촉구하는데 있다. 따라서 본 연구에서는 안전색채와 안전표지에 대해 알아보고 이를 사용한 실례를 통하여 안전색채와 안전표지의 색채 및 디자인에 대해 알아보고자 한다.

This research paper surveyed the awareness of general administrative officials who oversee the disaster management and firefighting officials who take part in emergency rescue work in local governments on disaster response exercises. The result of the survey showed that both officials acknowledged the need of the equipment used in disaster response exercises, securing the budgets for exercises, establishing a network among related institutions, reflecting actual conditions and local characteristics to the exercises, reflecting the result of exercise evaluations to the disaster response manual and next exercises, and securing a command communication system required for exercises.

현대 해양선박은 PLC 등 기존의 OT 시스템과 선박자동식별시스템 등 IT 시스템의 접목으로 스마트선박, 자율운항선박으로 진화되고 있다. 하지만 이러한 기술 통합은 공격이 가능한 접점이 늘어나며, 이는 사이버보안 위협을 증가시키고 있다. 선박은 대부분 항만으로부터 고립된 환경에서 운영되기 때문에 사이버공격이 발생 시 외부의 기술 지원이나 긴급대응이 어려워진다. 이러한 배경으로 해양선박을 대상으로 하는 사이버 복원력은 해양선박 환경에서 중요한 개념으로 자리잡고 있다. 본 논문은 해양선박 환경 표준 통신 네트워크인 SAN을 분석하고, 사이버 복원력을 소개한 후, NIST의 사이버 복원력 모델을 기반으로 해양선박 대상 사이버 복원력 연구를 분석한다.

A lot of people were trapped in elevators without power supply when BLACK-OUT situation occurred in 2011. The telephone network of control room connected to the elevators had problem operating poorly. In this paper we propose an ICT based elevator emergency call device prototype system and evaluate the performance of the system. The proposed system quickly responds in emergency situation to guarantee passenger safety. For the goal, firstly the system tries to connect to a control room. If it fails the system attempts to call numbers for emergency contact and a rescue team sequentially. The system is designed to quickly support emergency contact as well. Finally, the information of elevator failure is rapidly transferred to the failure process device by the proposed system.

For the purpose of cost saving and sales promotion, various industry companies have introduced logistics management techniques in their field. However, enterprises faced to damages because proper products can not be provided to customers in basic logistics 3S1L(speedy, safely, surely, and low) principles for environments changing rapidly and inflexible business processes. So, we need the ability in coping with risk to handle this phenomenon. In particular, the shipper of key decisions of supply chain risk management requires continuous exchange and collection of logistics information in the third-party logistics. However the current SCRMS(Supply Chain Risk Management System) is not sufficient to cover the shipper's various needs and to recognize and respond to emergency situations. Therefore, this paper proposes an active SCRMS framework through the reconsideration about the previous research on SCRM and rearrangement of risk factors for coping with those problems. in addition, it verifies an efficiency through a stability comparison with the current system.

This paper introduces an efficient USN (ubiquitous sensor network) for monitoring blind areas in a skiing resort, developed as a part of u-Sport showcase project of Gangwon Province. Blind areas of a skiing resort are dangerous and/or steep areas located aroud ski slopes, which are rarely traveled and not easily seen by a ski patrol. If an accident occurs in such a blind area, the main control center of the sking resort can hardly recognize the accident and provide first aid and rescue services promptly. The blind area monitoring system proposed in this paper monitors a blind area of a skiing resort using five battery-powered sensor nodes each of which has an image sensor on it and wirelessly transmits images around the blind area to the main control center on a regular basis, therebly allowing real-time monitoring of the blind area and prompt rescue services in case of accidents. Additionally, the monitoring system provides an emergency button which skiers injured in the blind area can push. If the button is pushed, an image around the button and an alarm signal are transmitted to the main control center and therefore the main control center can take prompt actions for rescuing the injured skiers.

Including heat wave, Climate change caused 150,000 casualty in 2000 and heat waves are meteorological events that pose a serious threat to human health. A heat wave is defined as "a period of abnormally and uncomfortably hot and usually humid weather". There is a need for the prevention of health effects due to weather and climate extremes. This study intends to propose the necessity of Response System to correspond to extreme heat. And this research focused on Cooling Center manual of facility and maintenance for extreme heat disaster. It would be useful to be planned based on community and to be taken a role as an E.O.C.(Emergency Operating Center). As a conclusion elderly watching system and the requirements regional cooling center facility was proposed.

On-site Algae Collecting System (OACS) is one of urgent countermeasures to clean the raw water when the algae blooms severely. Rapid reaction capability, high efficiency and large capacity are required when applying OACS to large water areas. The total performance of OACS are always determined by unit process named Flotation, Trapping and Collection. The working efficiency and daily treatment quantity of OACS can be increased when it runs automatically. As the rapid development of OACS technology, in the first place, equipment are miniaturized and simple. And in the second place, automation process from Trapping to Collection are advanced. So, They produce results higher working efficiency, smaller residual sludge on treated water, system's advanced environmental friendly features and the increased amount of sludge by Collection process to achieve large capacity. Now OACS has overcome the algae multiplication rate to ensured the amount of removal algae. In another aspect, it is high economically feasible because of reducing operation cost against the large capacity.
