본 연구에서는 지식경영의 성공요인들이 지식경영활동들을 활성화시키고 이어서 이러한 지식경영활동들이 업무성과에 미치는 영향에 대해서 재난관리 분야에 있어서 실증적으로 연구하였다. 지식경영성공요인은 리더십, 조직문화, 정보기술, 측정, 보상체계, 지식품질의 6개 요인으로 측정하였고 지식경영활동은 지식창출과 지식활용으로 구분하여 측정하였으며 재난관리 업무성과는 AHP를 통해서 도출된 12개 항목으로 측정하였다. 실증 연구의 결과 첫째, 지식경영성공요인 중 조직문화, 정보기술, 보상체계, 지식품질의 4개 요소가 지식창출활동을 활성화시키는 영향력을 나타내었고, 리더십, 정보기술, 보상체계, 지식품질의 4개 요소는 지식활용에 영향을 미치고 있는 것으로 나타났다. 둘째, 지식창출과 지식활용간의 관계에서는 지식창출이 지식활용에 영향을 주는 것으로 나타났다. 마지막으로 지식경영활동과 재난관리업무성과간의 관계에서는 지식활용이 재난관리업무성과에 영향을 주는 것으로 분석되었다. This study empirically explores the relationship among knowledge management success factors (leadership, organizational culture, information technology, measurement, incentive, knowledge quality), knowledge management activities(knowledge creation and knowledge use), and task performance in disaster management area. Findings suggest that (1) organization culture, information technology, incentive and quality of knowledge are significantly related to knowledge creation activities while leadership, information technology, incentive and quality of knowledge are significantly related to knowledge use activities, (2) higher level of knowledge creation is related to high level of knowledge use, and (3) the level of knowledge use activities seems to be significantly related to task performance in disaster management, while knowledge creation activities are not.

The proposed system supports the operation of national crisis alert and decision-making using the information accumulated from the level of crisis alert (Attention - Caution - Alert - Severe) and disaster damage. The crisis alert system consists of a data storage system, which analyzes crisis alerts and accumulates crisis alert information, and a crisis alert visualization system, which visualizes the results of crisis alert level determination and supports crisis response activities. First, the data storage system collects and links disaster and safety information and then stores and manages it through standardization and quality management. Second, the crisis alert visualization system, which was developed as a GIS display function to issue national/regional crisis alert levels for disaster types, is implemented to support crisis situation managers situation decision by displaying the crisis alert situation on the GIS situation dashboard in real time.

Although 3D-complex fractionated atrial electrogram (CFAE) mapping is useful in radiofrequency catheter ablation for persistent atrial fibrillation (AF), the directions and configuration of the bipolar electrodes may affect the electrogram. This study aimed to compare the spatial reproducibility of CFAE by changing the catheter orientations and electrode distance in an<i> in -silico </i>left atrium (LA). We conducted this study by importing the heart CT image of a patient with AF into a 3D-homogeneous human LA model. Electrogram morphology, CFAE-cycle lengths (CLs) were compared for 16 different orientations of a virtual bipolar conventional catheter (conv-cath: size 3.5 mm, inter-electrode distance 4.75 mm). Additionally, the spatial correlations of CFAE-CLs and the percentage of consistent sites with CFAECL<120 ms were analyzed. The results from the conv-cath were compared with that obtained using a mini catheter (mini-cath: size 1 mm, inter-electrode distance 2.5mm). Depending on the catheter orientation, the electrogram morphology and CFAE-CLs varied (conv-cath: 11.5±0.7% variation, mini-cath: 7.1±1.2% variation), however the mini-cath produced less variation of CFAE-CL than conv-cath (p<0.001). There were moderate spatial correlations among CFAE-CL measured at 16 orientations (conv-cath: r=0.3055±0.2194 vs. mini-cath: 0.6074±0.0733, p<0.001). Additionally, the ratio of consistent CFAE sites was higher for mini catheter than conventional one (38.3±4.6% vs. 22.3±1.4%, p<0.05). Electrograms and CFAE distribution are affected by catheter orientation and electrode configuration in the<i> </i><i>in -silico</i> LA model. However, there was moderate spatial consistency of CFAE areas, and narrowly spaced bipolar catheters were less influenced by catheter direction than conventional catheters.
