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.

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.

The purpose of this study is to find the relationship between GMS image data and hourly observed rainfalls data. Heavy rainfall cases over South Korea on 10th September 1990 and on 29th July 1993 were selected for studying of the relationship between the image data and rainfalls. First, image data were converted to TBB(Temperature of Black Body) and albedo and then these values were extracted for the pixels closest to the surface observation stations to correlate with the rainfall data. Horizontal distribution of TBB and albedo tells roughly rainfall regions. The correlation between rainfall and TBB is found to be very low in quantitative analysis. The weak relationship between the brighter albedo and the higher rainfall probability is observed. This study suggests that the TBB values are useful in classifying rain areas and for heavy rainfalls the albedo values are more useful than the TBB. Low linear correlation between the fields may be attributed to the neglect of cloud types in this study.

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.

GMS 상층운량을 이용한 1993년과 1994년의 동아시아 몬순대류의 특성

여름 몬순 강우가 대조적이었던 1993년과 1994년의 동아시아 여름 몬순의 특성이 조사되었다. 동아시아 지역에서의 몬순 특징을 조사하기 위해, GMS 구름양, 지표 조건인 해면 온도 그리고 여름 강우량이 분석되었으며, 위도/경도 2도 격자의 5일 평균 GMS 상층 운량의 분석을 통해 대류 활동의 자세한 이동과 지속성에 대한 1993년과 1994년의 특성이 비교되어 논의되었다. 몬순 구름의 이동과 발전에 대한 계절안 진동의 공간 및 시간 구조를 묘사하기 위해 20일의 창의 크기로 구성된 확장·경험적 직교 함수 분석이 각 해에 대해 수행되었다. 또한 적도 대류체의 주기성을 찾기 위해 퓨리에 조화 분석이 각 해에 적용되었다. 계절안 진동은 61일과 15일 모드가 적도 및 아열대에서 가장 탁월하였다. 그러나 이 탁윌 모드들은 적도 서 태평양과 인도양에서 각 해마다 다르게 나타났다. 그러므로 대조적인 동아시아 몬순 강우는 저 위도 해역에서의 대류 활동의 계절안 진동 및 계절 변화의 상호 작용과 더 근원적으로 관련되어 있을 것으로 본다. The characteristics of the Asian summer monsoon have been investigated for the periods of 1993/1994, the contrasting years in a view of the summer monsoon precipitation. In order to investigate the monsoon features over the eastern Asian monsoon region, the cloudiness(using the extensive data derived by the geostationary meteorological satellite), the condition of underlying surface including sea-surface temperature, and the summer rainfall are analyzed and some comparisons with 1993 and 1994 are also made and the characteristic differences are discussed. An analysis of the 2-degree latitude-longitude gridded 5-day mean high cloud amount data shows the detailed movement and persistence of the convective activities. In order to describe the spatial and temporal structures of the intraseasonal oscillation for the movement and evolution of the monsoon cloud, the extended empirical orthogonal function analysis with the twenty-day window size is used for the each year. Also, in order to find out the periodicity of the equatorial convective cluster, Fourier harmonic analysis is applied to the each year. The most prevailing intraseasonal oscillations of high cloud amount are 61 day mode and 15 day mode in the equatorial and the subtropical oceans. However it was found that the most prevailing modes over the equatorial western Pacific and Indian Ocean were different for each year, hence raising the possibility that the contrasting monsoon precipitation may be more fundamentally related to the interaction of intraseasonal oscillations and seasonal variation of convective activities over the lower latitude ocean.
