In this study, the influence of explosion over-pressure caused by the rupture of bonded container LPG used as a propellant was calculated by using the Hopkinson's Scaling Law and the accident damage was estimated by applying the influence on the adjacent structures into Probit model. The overpressure calculated by probit model up to 4 m of interest is 55 kpa, This is an overpressure where all buildings are destroyed, The limit distance of structure damage was 15 m and the limit of glass damage was 45 m. As a result of this, in this study, 100 % of the explosion efficiency is applied, and the actual damage effect due to the explosion of the bonded container is considered to be less than the value calculated in this study.

Carbon monoxide is colorless, odorless gas generated when carbonic fuel attains an incomplete combustion. As carbon monoxide is slightly lighter than air, and 200 - 250 times stronger than oxygen in affinity of hemoglobin, when carbon monoxide is inhaled, this can cause carbon monoxide poisoning as it is easily combined with hemoglobin in blood, and the oxygen transport ability of blood is lost, which leads to a situation of suffocation. An accident took place that involved the death of two divers who wore air containers compressed by using air compressors, and dove into the sea to harvest sea cucumber. In about 10minutes after they started harvesting, they came out to, collapsed on the land, and died. The compressed air they used at that time was very fatal as carbon monoxide accounted for 0.10- 0.25 % of the compressed air. The actual straight distance of the air inlet of air compressor was about 80 cm away from an outlet of exhaust gas, which was very close between inlet and outlet. This indicates that the air compressor was in a structurally deficient state in that some exhaust gas can be inhaled through the inlet as the height of the inlet was the same as that of the outlet. This study herein investigated the chance of containing carbon monoxide in case that air is compressed by air compressor. The air compressor was connected with rubber belt and motor, internal combustion engine that obtains energy by burning gasoline, and carbon monoxide accounted for 0.6 - 1.3 % of exhaust gas of the motor. Carbon monoxide was not detected in the air compressed in a windless condition; whereas carbon monoxide was detected as exhaust gas was intruded through an air inlet due to the effect of wind, and the content of carbon monoxide increased by 0.05 % or above. Furthermore, the content of carbon monoxide increased by 0.25 % or above after about 20 minutes when the air compressor was used indoor, not outdoor, which is a very dangerous situation. Therefore, for safe air compression, an exhaust pipe should be installed so that exhaust gas cannot be intruded into air inlet, and air compression should be conducted outdoor as indoor air compression puts even a person who compresses air into danger. By dong this, accidents can be prevented.

Early in the summer, A carbon monoxide poisoning accident occurred inside the car that was stopped on the shoulder of the road. The windows were closed and the air conditioning was turned on. All five passengers was unconscious. Their blood carbon monoxide-hemoglobin(CO-Hb) content was 31.0 %~ 39.5 % range. If they were a little more exposure to carbon monoxide, All of them would have died. The carbon monoxide concentrations were measured in the indoor 0.073 % and in the trunk 0.136 %. The concentration was higher in the trunk than indoor. The exhaust gas pipe was bent to the inside of the rear bumper due to an accident. The car's exhaust gases does not spread into the air, and spread to the inside of bumper. The air passage in the trunk is damaged, the exhaust gas flow in easily, and spread into the indoor.

최근 발생한 일본 원자력 발전소 방사능 오염수 유출사고로 국민의 수산생물 및 해수의 안전성에 대하여 경각심이 고취되고 있다. 본 연구에서는 고리 원자력 발전소를 대상으로 방사능 오염수의 해양유출 사고가 단기간 발생할 것을 가정하여, 조류, 해류 및 해상풍 자료를 활용하여 피해 예상해역과 해역별 방사능 농도 분포를 추정하였다. 위기 대응 방안은 양식업과 어선어업으로 구분하여 살펴보았다. 양식업의 경우 상황별 각 3단계로 구분하여 현재체제 유지, 조기출하와 폐기 준비, 양식생물 및 시설물 폐기로 나뉠 수 있다. 어선어업의 경우, 각 어업별로 피해예상 해역의 조업을 금지하고, 관련기관의 예측 정보를 주시하며, 어획된 어획물을 분석기관에 송부하여 지속적인 오염여부 판단을 모니터링 할 필요가 있다. 또한 예측 정보에 따라 탄력적으로 어획 해역을 축소시키거나 이동시켜 나가는 노력이 필요할 것이다.
Recently, it is arouse people's attention to the alert of radioactivity contamination for fisheries resources and ocean water by the occurrence of radiation leakage accident at the Nuclear Power Plant of Fukushima, Japan. Assuming the short-time radiation leakage accident at the Gori Nuclear Power Plant, we estimated the estimated damage oceanic area and distribution of radioactivity concentration at each oceanic area. Countermeasure for emergency was examined to aquaculture industry and fishing industry. In case of Aquaculture, we devided 3 level for each status; ① preservation, ② shipment in the early stage, ③ disuse the aquaculture resouces including construction. In case of Fishing, it is needed to ① prohibition the fisheries activities in the estimated damage fishing grounds, ② close observation to prediction informations by related organizations and ③ sending the fhisheries sample to analysis organizations for decision whether it is polluted or not. Moreover, ④ it is also needed to flexible reduction effort of fishing grounds according to the prediction informations.

2011년 3월 발생한 해저지진으로 인해 일본 후쿠시마 제1원자력발전소의 사고가 발생하였다. 이로 인해 다량의 방사성물질이 해수 중으로 유입되었다. 후쿠시마 제1원자력발전소 사고 후 방사성물질은 전 세계적으로 문제화 되었다. 특히 우리나라는 일본과 인접하고 있어, 일본 후쿠시마 원자력발전소에서 누출된 방사성물질에 대해 우리국민은 직접적인 피해를 걱정하였다. 방사성물질은 대기 및 해양을 통해 이동과 확산을 하며, 해양생물의 체내에 농축되기도 한다. 따라서 해양에서 해수 및 해양생물 시료를 채취할 수 있는 해양조사 체계 구축은 물론 우리나라 주변해역의 해류 흐름을 파악할 수 있는 위성자료의 데이터베이스화 및 해양의 해류에 대한 예측모델의 구축이 필요한 실정이다. 예측모델을 기반으로 본 연구에서는 해양에서 방사성 물질의 이동과 확산, 해양생물 체내 농축에 대한 종합적인 위기관리 시스템 구축방안을 제시한다.
Highly radioactive materials have been released into the ocean at the Fukushima Nuclear Power Plant, following the Tohoku earthquake and tsunami on 11 March 2011. The Japanese leakage accident became one of the most serious global issues. It especially draws concern from Koreans who fear possible direct radiation exposure due to their geographic closeness and distrust Japanese government information on radiation. {According to a report published on 29 October 2011 by a French research institute, the pollution of the Pacific Ocean was probably 30 times bigger than the Tokyo Electric Power Company reported in May 2011.} Radioactive substances usually spread through air and oceans, and can be accumulated in marine life and eventually in human body. To minimize the potential radiation exposures and long-term effects on human health, we propose to design and establish an integrated crisis management system. Under this system, sea water and biological samples will be periodically and extensively collected to detect and identify spatial and ecological pathways of radioactivity. Together with data from satellites, the collected data will be utilized to forecast the magnitude and dispersion of radioactivity by developing a bio-physical coupling model that combines general oceanic circulation and ecological models.

Recently, global warming problem is a major issue in international community. The carbon dioxide (CO2) emissions in the construction industry is one of the main factors causing a global warming problem. Accordingly, various researches on CO2 emissions caused by the construction industry is needed and construction methods which is low CO2 emission should be developed. In this study, CO2 emission cost is compared with tile work types in construction phase. As a result, the CO2 emission costs of tile work is the highest. This project basic information for selecting appropriate construction methods in aspect of low CO2 emission cost.
