2001년 9 11 테러 이후 미국에서 탄저균을 이용한 생물테러가 발생한 이래 미국을 비롯한 여러 나라에서는 생물무기 및 생물테러에 대한 대응방안들이 준비되고 있다. 따라서 이런 대응방안과 더불어 생물무기를 쓰는 테러리스트의 행동과 위협에 대비를 할 필요가 있다. 생물테러 전염병은 치명률이 높고, 인간 상호간에 전염이 용이하며 치료하기가 어려우므로, 인명의 손실을 최소화하기 위해서는 보건의료기관 등에서 근무하는 보건의료인이 생물테러로 의심되는 병원체 및 전염병을 조기에 인지하는 것이 가장 중요하다. 따라서 보건분야 전문가들은 환자나 일반 대중, 그리고 다른 보건전문가들에게 생물무기와 생물테러에 의해 퍼질 가능성이 있는 질병들에 대해 신중하게 대응할 수 있는 방법들을 교육해야 한다. 질병이 발생했을 때 보건전문가들은 조사에 착수할 역학자들과 협조를 해야 하고, 임상 또는 연구소에 일하는 보건전문가들은 생물무기로 사용될 수 있는 병원체나 생물무기를 생산하는데 사용되는 시설에 접근하는 것을 제한하도록 도울 수 있다. 2005년 질병관리본부 생물테러대응팀에서는 의료인, 다중시설이용 근무자, 보건요원을 대상으로 생물테러 인식도를 조사한 바 있다. 조사결과, 의료인에 대한 생물테러 교육 및 교육훈련의 필요성에 대해 94.2%가 필요하다고 응답하였다. 이런 자료를 바탕으로 하여 국내에서도 생물테러교육의 필요성이 대두되기 시작하였다. 본 연구는 미국, 영국에서 진행되고 있는 생물테러 관련 교육에 대한 관련 자료와 사례를 문헌 분석을 통해 우리나라에 맞는 생물테러 교육에 대한 방향을 제시하고 문제중심학습모듈을 개발하고자 하는데 그 목적이 있다.

The continuing urbanization and industrialization around the world has required a large amount of power. Therefore, construction of major infrastructure, including nuclear power plants in coastal areas, has accelerated. In addition, the intensity of natural disasters is increasing due to global warming and abnormal climate phenomena. Natural disasters are difficult to predict in terms of occurrence, location, and scale, resulting in human casualties and property damage. For these reasons, the disaster scale and damage estimation in coastal areas have become important issues. The present study examined the predictable weather data and regional ratings and developed estimating functions for wind wave damage based on the disaster statistics in the southern areas. The results of the present study are expected to help disaster management in advance of the wind wave damage. The NRMSE was used for verification. The accuracy of the NRMSE results ranged from 1.61% to 21.73%.

In the area of disaster management, we have more focused on the rapid response and recovery, but preventive approach for disaster is becoming more and more important. For mitigation of disasters, we need to analyze the vulnerable area according to each disaster, and need to manage those area systematically. In this research, we selected the fire as a type of disaster, developed guideline of construction of vulnerability map of fire, and built the vulnerability map of fire in Changshin-Dong, Jongro-Gu, Seoul as a case study area. The vulnerability map of fire can be applied to grasp the vulnerable area in advance and manage it systematically. In addition, it can also be applied in the landuse planning and the rearrangement of infrastructure for the mitigation of disaster when we build detail city planning.

Precipitation has a wide range of applications, such as the management and operation of dams and rivers, supply of dranking water for urban and industrial complex, farming and fishing, forest greening, and safety management. In order to prepare for disasters and to obtain economical effects in case of flood damage, it is necessary to measure accurate precipitation. In this study, we carried out the characteristics tests for various types of rainfall gauge using integrated verification system, which can analyze the performance of collective type rainfall gauge. The uncertainty for tipping bucket rain gauge was 0.2887 mm. Therefore, it can be seen that the uncertainty is calculated differently depending on the characteristics of the rainfall gauges. The uncertainty is also influenced greatly by the resolution.

Recently, there has been an increasing need for underwater communication systems to monitor ocean environments and prevent marine disasters, as well as to secure ocean resources. Most underwater communication systems adopted acoustic communication with a consideration of attenuation, absorption, and scattering in conductive sea water, and developed fully digital modems based on processors. In this study, a digital up converter (DUC) and a digital down converter (DDC) was developed for an underwater basestation based on underwater acoustic communication systems. Because one of the most important issues in underwater acoustic communication systems is low power consumption due to environmental problems, this study developed a specific hardware module for DUC and DDC. It supported four links of underwater acoustic communication systems and converted the sampling rate and frequency. The systemwas designed and verified using Verilog-HDL in ModelSim environment with the test data generated from baseband layer parts for an underwater base station.

Rapid developments of IT technology has been creating new security threats. There have been more attacks to get patients' sensitive personal information, targeting medical institutions that are relatively insufficient to prevent and defend against such attacks. Although the government has required senior general hospitals to get the ISMS certification since 2016, such a requirement has been burdensome for small and medium-sized medical institutions. Therefore, this study was designed to draw measures to identify and improve the privacy status of the medical institution by dividing it into management, physical and cyber areas for small and medium-sized medical institutions. The results of this study showed that the government should provide financial support and managerial supervision for the improvement of personal information protection of small and medium-sized medical institutions. They also suggested that the government should also provide medical security specialists, continuous medical security education, disaster planning, reduction of medical information management regulations not suitable for small and medium sized institutions.

Recently, many unmanned aerial vehicle (UAV) studies have focused on small UAVs, because they are cost effective and suitable in dangerous indoor environments where human entry is limited. Map building through distance measurement is a key technology for the autonomous flight of small UAVs. In many researches for unmanned systems, distance could be measured by using laser range finders or stereo vision sensors. Even though a laser range finder provides accurate distance measurements, it has a disadvantage of high cost. Calculating the distance using a stereo vision sensor is straightforward. However, the sensor is large and heavy, which is not suitable for small UAVs with limited payload. This paper suggests a low-cost distance measurement system using a laser pointer and a monocular vision sensor. A method to measure distance using the suggested system is explained and some experiments on map building are conducted with these distance measurements. The experimental results are compared to the actual data and the reliability of the suggested system is verified.
