정확한 국가보건통계 데이터베이스는 보건정책의 기초가 되지만, 우리나라에서는 아직 신뢰할만한 통계를 생산해내지 못하고 있는 것이 사실이다. 의료보험자료를 기초로 해서 만드는 보건통계가 있지만 여러 면에서 신뢰도가 떨어진다는 의견들이 많다. 이에 저자들은 대안으로서 각 병원의 의무기록실에서 생성하고 있는 통계들이 국가보건통계의 기초가 될 수 있는 지를 알아보기 위해 78개 병원을 대상으로 통계 생성여부와 전산화 정도를 조사하였다. 설문은 병원표준화 심사와 서비스평가, OECD에서 요구하는 통계들을 참고로 하여 작성하였으며, 해당 통계를 생성하고 있는지, 통계생성 작업이 어느정도 전산화되어 있는지를 물었다. 응답한 병원의 50% 이상이 통계를 생성하고 있다고 하였으며, 통계를 생성하고 있는 병원에서 전산망을 이용하지 않고 수작업으로 하고있는 비율은 1.3%에서 7.7% 사이였다. 설문서에서 질문한 통계를 생성하지 않고 있다고 응답한 병원의 대부분은 전산화 되어있지 않았다. 이상의 결과로부터 각 병원의 의무기록실에서는 많은 부분 국가보건 통계에 필요한 각종 통계량들을 생성해 내고 있으며, 통계 생성 방법은 전산화 되어있고, 따라서 이를 수집, 가공하면 국가보건통계 데이터베이스를 구축할 수도 있을 것이라는 결론을 얻었다. 이를 위해서는 통계량을 정의하는 표준화 사업이 선행되어야 할 것이다 We surveyed the generation rate of health statistics by medical records offices of the 78 hospitals and its automation rate using computerized hospital information system. Structured questionnaire was given to one medical record officer of each hospital. Items in the questionnaire was selected from statistics required for hospital service evaluation or OECD health statistics. More than 50% of the medical record office generated questioned health statistics, and most of them was automated. Because many of the medical record offices of the hospitals are producing essential health statistics and automated, the is a possibility that we can collect and use these datas to build up national health database if adequate standardization procedure can be implemented.

Suh, Ae-Sook,Oh, Hyun-Mi,Ha, Kyung-Ja,Song, Byung-Hun,Kim, Jeong-Hee,Yi, Gi-Chul 東亞大學校 建設技術硏究所 2004 硏究論文集 Vol.27 No.2

Comparison between the Tropical Rainfall Measuring Mission(TRMM) precipitation radar(PR) and the C-band Doppler radar at Kunsan. Pusan and Cheju, operated by the Korean Meteorological Administration (KMA). is conducted for validation of the surface precipitation structure, and for calibration of KMA radar instrument. Data used in validation was selected for seven rain events in the south region of 36.5oN and at TRMM overflight in Korea. during the summer season of 2000. Quantitatively comparing radar reflectivities from two different platforms that have different view angles. bandwidths. and frequencies is a challenging task. For the comparison. the precipitation patterns are projected on the same area for TRMM PR. Through the comparison, it is realized that the precipitation retrieved from ground-based radar is under estimated by the area-mean based data, compared to TRMM PR observations. We discuss that is underestimation may be produced by the Z-R parameter for the stratiform rain.

Korea has been influenced by Asian dust since January 2001. These Asian dust not only causes low visibility but also is harmful to human health. Monitoring Asian dust by satellite detection is most important in the point of long range transportation and wide area detection. We derived an algorithm far Asian dust detection using Korean Multi-Purpose SATellite/Ocean Scanning Multi-spectral Imager(KOMPSAT/OSMI). To obtain the best wavelength band in 6 spectral bands of OSMI for detection of Asian dust, the spectral data were analyzed. We also compared in developed algorithm spectral characteristics of OSMI with that of SeaWiFS which have the same wavelength range. The result showed that band 7(765nm) and 8(865nm) of OSMI had the best spectral distribution. Therefore, only two bands were applied to the algorithm for Asian dust detection. In a case study, Asian dust could be detected on April 13, 2001 from the algorithm. The dust had appeared aver the Southern part of Korean including Che-ju island and showed the aerosol optical depth in the range of 0-0.8 in OSMI band 8, especially 0.5 near Cheju island. The results are similar to that of MODerate resolution Imaging Spectroradiometer (MODIS) Level 2 products.

서애숙 ( Ae Sook Suh ),김금란 ( Kum Lan Kim ) 大韓遠隔探査學會 1990 大韓遠隔探査學會誌 Vol.6 No.1

This is the study about the meteorological satellite cloud image classification by objective methods. For objective cloud classification, linear discriminant analysis was tried. In the linear discriminant analysis 27 cloud characteristic parameters were retrieved from GMS infrared image data. And, linear cloud classification model was developed from major parameters and cloud type coefficients. The model was applied to GMS IR image for weather forecasting operation and cloud image was classified into 5 types such as Sc, Cu, CiT, CiM and Cb. The classification results were reasonably compared with real image.

현재 전세계적으로 널리 사용되고 있는 드보라크 방법에 의한 태풍강도 분석법을 1991년 우리나라에 영향을 준 6개 태풍사례에 대해 실제 적용하여 강도분석을 하였다. 또한 분석된 태풍 강도를 이용하여 태풍의 중심기압과 최대풍속을 산출하는 상관 관계식을 계산하여 제시하였다. ORCHID 태풍에 이 관계식을 실제 적용하여 관측값과 비교하여 그 정확도를 평가하였다. 그 결과 중심기압(MSLP: Minimum Sea Level Pressure)과 최대풍속(MWS: Maximum Wind Speed) 이 관측값보다 약간 낮은 값을 보였지만 전체적인 패턴은 비슷하게 나타났다. 그러나 미국 국립 해양 대기청(NOAA) 및 일본 기상청(JMA)에 의해 작성된 상관 관계표로 산출된 값은 관측값과는 많은 차이를 보여 주었다. One of the world widely used methods in determining the intensity of a typhoon is Dvorak`s technique. By applying the Dvorak`s method to the typhoons which affected our country in various degrees and extents without regard to their individual severity, we estimated their intensity for six different cases of typhoons. We have derived a regression equation of estimating the central pressures and maximum wind speeds for the six selected typhoons. Their intensity was estimated from the Dvorak`s method using GMS satellite image data. The derived equation has tested to typhoon ORCHID and the computed values have been compared with the direct observations in its central pressure and maximum wind speed. The computed values on the Dvorak`s method are smaller in their magnitudes than the observed corresponding values. But their relative magnitudes do not change so much at each different time step. But our results are significantly different from those of NOAA and JMA. The cause of differences are not investigated in depth in this analysis.
