In order to provide an effective preparedness for a nuclear or radiological emergency happening in the domestic or neighborhood countries and to solve the vague fear of the people for the ingestion of radioactive livestock products, the establishment of national guideline level for radionuclides in feed is urgently necessary. This is because it is important to secure the safety and to manage the crisis in the agricultural, fishery and food sector by performing the effective safety control during and after nuclear incident. This study was performed to investigate the report cases of international organizations and foreign countries to set up a domestic control standard for managing radioactive substances that may be contaminated in animal feeds due to the nuclear power plant incident. In addition, an attempt was made to provide a useful reference that can help prepare a domestic control standard, using a coefficient that can consider the transfer into livestock through the intake of radioactive contaminated animal feeds. The standard radioisotopes investigated were confined to radioactive cesium ($^{137+134}Cs$) and iodine ($^{131}I$). Guideline level for the radionuclides was calculated by using the transfer coefficient factor and the maximum daily intake of animal feed provided by IAEA. For example, the maximum daily intake of animal feed was set as $25kg\;d^{-1}$ for dairy cows, $10kg\;d^{-1}$ for beef cattle, $3.0kg\;d^{-1}$ for pigs and $0.15kg\;d^{-1}$ for chickens. The result values for radioactive cesium were calculated as $8,696Bq\;kg^{-1}$, $4,545Bq\;kg^{-1}$, $1,667Bq\;kg^{-1}$ and $2,469Bq\;kg^{-1}$, respectively. The results for radioactive iodine showed the ranges between $741Bq\;kg^{-1}$ and $76,628Bq\;kg^{-1}$. These data can be utilized as a scientific reference for the preparation of a crisis management manual for the emergency control due to nuclear power plant accident in Korea and neighboring country. These results will contribute to establish the safe feed management system at national level as manual for responding the radioactive exposure of agricultural products and animal feeds, which are currently not established.

A severe crushing injury of the chest produce a very striking syndrome referred to as traumatic asphyxia. This syndrome is characterized by bluish-red discoloration of the skin which is limited to the distribution of the valveless veins of the head and neck. And also if it is characterized by bilateral subconjunctival hemorrhages and neurological manifestations. But these clinical entities faded away progressively in a few weeks. Apporximately 90% of the patients who live for more than a few hours will recover from traumatic asphyxia when it occurs as a single entity. And so, death results from either severe associated injuries of from subsequent infection, rather than from pulmonary or cardiac insufficiency in traumatic asphyxia. We have experienced 4 cases of traumatic asphyxia with severe crushing thoracic injuries at department of the chest surgery, Captial Armed forces General Hospital during about 3 years from April 1977 to Aug. 1980. The 1st 22 year-old male was struct 2$\frac{1}{2}$ ton truck on the road and was transferred to this hospital immediately. He had taken tracheostomy due to severe dyspnea with contusion pneumonia and for removal of a large amount of bronchial secretion. The 2nd case was 23 year-old male who was got buried in a chasm. In this case, the heavy metal post tumbled over him back while at work. The 3rd case was 39 year-old male who leapt out of a window in 5th story while fire broke out in living room by oil stove heating. He had multiple rib fracture with right hemothor x and right colle's fracture and pelvic bone fracture. The last 22 year-old male was run over by a gun carriage. The wheel of this gun carriage passed over his thorax and right chin. He was brought to this hospital by helicopter. when he was first examined at emergency room, he was in semicomatose state and has pneurmomediastinum with multiple rib fracture and severe subcutaneous emphysema. As soon as he arrived, bilateral closed thoracostomy was performed and cardiopulmonary resuscitation was done. In hospital 8th weeks, chest series showed fibrothorax in right side even if chest wall stabilized. All 4 cases had multiple petechiae over their facees and chest and bilateral subconjunctival hemorrhages referred to as traumatic asphyxia. 3 cases except one case who received splenectomy, had been suffered from contusion pneumonia and had been treated with respiratory care. In these 3 cases, they had warning of impending injury before accident, and took a deep breath hold it and braces himself. And also, even if he had not impending fear in remaining one case, he had taken a deep breath and had got valsalva maneuver for pulling off the heavy metal post. Intrathoracic pressure rose suddenly and resulted to traumatic asphyxia in this situation. All these cases were recovered completely without sequelae except one fibrothorax, right.

사회 환경이 급변하는 예측 불가능한 시대에 범죄로부터의 안전에 대한 국민적 관심이 높아지고 있다. 범죄에 대한 두려움 없는 삶을 영위하기 위한 욕구가 증대되면서 안전도시 구축에 관한 관심은 점차 전국적으로 확산되고 있다. 이를 계기로 정부는 스마트 도시 안전망 구축을 위하여 스마트시티 통합플랫폼으로 지자체와 112, 119, 재난 등 공공재난안전 체계 연계사업을 추진 중이다. 본 연구는 지능형 방범 기술 개발 연구단에서 추진하고 있는 지능형 방범 사업 성과물과 스마트시티 통합플랫폼 간의 연계 방안을 마련하기 위해 해당 분야의 동향을 살펴보고 연계 시 고려할 사항들에 대한 5가지 기준 적용과 기술 및 제도적인 부문으로 연계 가능한 여부를 면밀히 검토하였다. 첫째, 통합운영센터 및 CCTV 관제센터가 주축이 되고 지자체 확산을 주목적으로 하고 있기에 연계 목표가 분명하며, 둘째, 시스템 부문은 사건 사고 관련 기관에 정보 제공하는 것이 가능하다는 것을 알 수 있었다. 셋째, 방범 부문에 시나리오 영역 확대가 가능하고 장기적 도시정보 통합 기반 조성이 가능할 것으로 전망되었고, 넷째, 스마트시티 로드맵에 반영과 관련 기관과의 지속적 협의 등을 통해 제품 실증이 가능할 것으로 전망되었다. 마지막으로 민간 기업의 상용화 제품을 지속적으로 추가하여 타 지자체 확산을 도모 할 수 있다는 것을 알 수 있었다.
