현재까지 우리나라 하천관리는 기존의 도면관리 및 현장조사를 통한 정보관리에서 벗어나 WAMIS, RIMGIS와 같은 물 관련 하천기본지리정보 시스템을 구축하여 사용되어 왔다. 하지만 기 구축된 시스템들은 선(線) 중심의 2차원 하천 공간자료로 관리되어 실무자 중심의 친환경적 하천관리업무 지원을 위한 자료로서 활용성이 부족한 실정이다. 본 연구에서는 면(面) 중심의 입체적인 3차원 하천공간정보 구현과 체계적인 하천관리업무가 가능하도록 항공사진(아날로그, 디지털) 및 다양한 위성영상에 대한 해상도 비교와 시설물 판독 분석을 통한 하천 적용여부 분석을 수행하였다. 하천 적용성 분석을 통해 가장 효과적으로 판단되는 디지털 항공사진을 이용하여 하천관리 및 활용방안을 모색함으로써 효율적인 하천관리방안을 제시하고자 한다. The river management in Korea had been focused on line based 2D spatial data for the developing river management application system. In this study, the polygon based 3D spatial data such as aerial photos and satellite images were selected and used through comparing their resolution levels for the river environment management. In addition, 1m detailed DEM (Digital Elevation Model) was constructed to implement the real topography information around river so that the damage area scale could be extracted for flood disaster. Also, the social environment thematic maps such as a cadastral map or land cover map could be used to verify the real damage area scale by overlay analysis on aerial photos or satellite images. The construction of these spatial data makes possible to present the real surface information and extract quantitative analysis to support the scientific decision making for establishing the river management policy. For the further study, the lidar surveying data will be considered as the very useful data by offering the real height information of riverbed as the depth of river so that flood simulation can give more reality.

The purpose of this study was to build a web-server for culture heritages management information system in order to efficiently manage and safely preserve undesignated cultural properties in the Namsan area in Kyeongju, which have been neglected so far. In order to achieve this purpose, data were collected on the basis of undesignated cultural properties in the study area. To acquire the location and range GPS were used and spatial data including geographic coordinates, visual materials and structured interviews were conducted through field survey. In addition, in order to obtained reliable and accurate locations of undesignated cultural properties which are scattered, DGPS(Differential Global Positioning System) were used. The spatial database was constructed based on the standard of cultural properties and attribute data was linked to geo-spatial information(digital map and aerial photographs). This system was built in a web-server environment. The result shows detailed description on the selected output for selected location and property information can be located on the map. In particular, a database to search for the status and modification of cultural properties will provide information to the users.

Background/Aims: The mortality of hospitalized patients undergoing treatment with an intra-aortic balloon pump (IABP) due to cardiogenic shock is well known as quite high. The aim of this study was to evaluate the outcome of percutaneous coronary intervention (PCI) with an IABP in patients with acute coronary syndrome (ACS) and cardiogenic shock and identify the predictors of in-hospital mortality. Methods: 134 patients who underwent PCI with IABP due to ACS complicated by cardiogenic shock were consecutively enrolled. Outcomes were obtained and analyzed during hospitalization and after 1 year. Results: The incidence of all-cause mortality was 35.8% (in-hospital mortality, 34.3%, 1-year mortality, 1.5%). The nonsurvival group exhibited higher peak levels of creatine kinase MB, lower ejection fractions, and higher incidences of ST elevation myocardial infarction, ventricular arrhythmia, and use of an assistive device than did the survival group. Aging (hazard ratio 2.839, 95% confidence interval 1.408-5.723, p = 0.004), the use of a temporary pacemaker (2.035, 1.114-3.720, 0.021), the use of a mechanical ventilator (4.376, 1.852-10.341, 0.001), and the performance of cardiopulmonary resuscitation (CPR) (2.219, 1.017-4.839, 0.045) were independent predictors for in-hospital mortality. However, out-of-hospital mortality among in-hospital survivors was not affected by predictors of in-hospital mortality. Conclusions: The incidence of in-hospital mortality was high, as expected in patients undergoing PCI with IABP due to ACS with cardiogenic shock. Aging, CPR, and additional procedures such as pacemaker use and mechanical ventilation were predictors of in-hospital mortality. However, the patients who were successfully discharged after the complex procedure showed acceptable 1-year outcomes. (Korean J Med 2015,89:186-191)
