Purpose: This study evaluated the pharyngeal airway space changes in CT images in patients receiving bilateral sagittal split osteotomy (BSSRO) for the surgical correction of mandibular prognathism. Methods: A total of 22 patients with mandibular prognathism were treated using BSSRO. Computed tomography was performed 1 month (T0) before surgery and, 1 month after surgery (T1). The anteroposterior length (AP), lateral width (LAT) and cross-sectional area (AREA) at the level of soft palate (C2) and base of the tongue (C3) were measured using CT images. Results: The mean amount of mandibular setback was 7.41 mm (${\pm}$3.46 mm). All the AP, LAT and AREA at the C2 and C3 level were decreased significantly 1 month after surgery (P<0.001). As the amount of mandibular setback was increased, the AP, LAT and AREA levels at the level of C2 and C3 had decreased. In addition, the reduction of the AREA at the C3 level was associated with the amount of mandibular setback (P<0.05). Conclusion: A significant decrease in pharyngeal airway space was observed 1 month after the operation. The cross-sectional area at the level of base of tongue was decreased with increasing amount of mandibular setback.

This study was performed as a part of survey for the operation and interim evaluation of the on-going pilot project of community health in Jeomdong-Myon, Yeoju-Gun, Kyunggi-Province since 1982. Seven Villages (Ri) were selected purposively for the survey from a total of 26 villages in Jeomdong-Myon, target area, under the consideration of the socio-economic background and the distribution of health resources. The target population was the women in age group of 15-44 years in that area and a total of 156 women were interviewed. This study was done by the interview survey using questionnaire which was composed with questions about MCH and FP. The results were as follows; 1) ln the status of maternal health, (1) the proportion of receiving antenatal care was relatively high (67.1%) in this area, but the starting time of antenatal care was delayed to 7 months or more of gestational period in 22 percent. Therefore some intervention would be necessary for advancing the time of antenatal care. (2) The proportion of home delivery was decreased according to the rank of birth-order. And more than 50 percent of delivery attendants were mothers-in-law or neighbors. The fact indicates that the health education for non-professional delivery attendents would be necessary for improving home delivery and the content of education would be preferable to focussing to the method of hygienic delivery attending. (3) The comprehensive health service and education would be recommended for the postnatal care, because of the extremely low rate of postnatal care in this area. 2) In the status of child health, (1) the pro-portion of breast feeding was 90.2 percent, and the weaning started after 12 months of birth in 12.7 percent. This indicates the necessity of education about the weaning program. (2) The proportion of completed basic vaccination was 39.6% and the main reason of missing vaccination was poor accessibility in terms of time. For that, the supply of vaccine to primary health care units (health subcenters) should be continuous, not infrequent nor occassional. 3) The proportion of respondants who were using contraceptive methods currently was 79.8 percent and in 44.7 percent they accepted the permanent contraceptive methods. Those results are distinct in this area. But it seems a serious health problem that 53.2 percent of respondants were experienced the induced abortion for birth control.

Purpose: This study aimed to analyze the visual and spatial elements of the gait of a stroke patient who had diverse ankle weight loads applied, according to weight changes. Methods: The subject was a 57-year-old stroke patient diagnosed and hospitalized with a left intracerebral hemorrhage. A weight equivalent to 0%, 1%, and 2% of his body weight was applied to the area 5cm upward from the ankle using a Velcro strap. He was then trained on a treadmill, receiving a six-minute walk test to evaluate his gait ability. A gait analyzer was used to collect visual and spatial elements, such as gait distance, gait velocity, cadence, step length, stride length, and swing phase, according to a weight load equivalent to 0%, 1%, and 2% of his body weight. Results: According to the results of applying 0%, 1%, and 2% of his body weight on the ankle, except for gait velocity, his gait distance, cadence, step length, stride length, and swing phase were higher when 1% of his body weight was applied compared to 0% or 2% of his body weight. Conclusion: Applying a weight equivalent to 1% of the body weight to the ankle positively affected the visual and spatial element of the gait and heightened the efficiency of exercise during treadmill training, a gait-training tool generally used for stroke patients. However, the result is difficult to generalize because the number of subjects was small with only one subject.

A decision support system, Watershed Analysis Risk Management Framework(WARMF), was applied to the Kyungan Stream watershed, a tributary of Lake Paldang, for calculation of total maximum daily loads(TMDL). The WARMF system was developed by Systech Engineering, USA, and has been successfully used in several watersheds, for TMDL studies. The study area was divided into 14 sub-basins, based on digital elevation model(DEM). The integrated watershed and stream model of WARMF was validated by flow and BOD data measured during the year of 1999. There were reasonable agreements between model results and field data, both in water flow and BOD. The validated Kyungan WARMF was extensively utilized to study the quantitative relationship between waste loads and receiving water quality. Based on TMDL guideline at Paldang Lake and Kyungan Stream, the water quality criterion were set to be 3.0mg/L, 3.5mg/L, and 4.0mg/L at the watershed outlet. The allowable waste loads of BOD, both from point and non-point sources, were determined at each water quality criterion. From this study, it was concluded that the WARMF provided several advantages over the conventional application of watershed and stream models for TMDL study, such as time variable simulations, multiple possible soutions, and reduction loads for goal water quality, etc.

Transboundary air pollution has recently become an area of increasing scientific interest and political concern as countries are receiving air pollutants from their neighbors. In order to gain a better understanding of the long-range transport processes of air pollutants and the source-receptor relationships among neighboring countries, an atmospheric transport model coupled with a RAMS(Regional Atmospheric Modeling System) model was applied to the East Asia region during the entire month of January 1993. The scalar transport option of the RAMS model was used to calculate special atmospheric constituents such as trace gases or aerosols. The sulfate production in clouds and rainwater and its removal processes by dry and wet deposition were considered. The sulfate budget from source regions to receptor regions was estimated by analysing the source-receptor relationships. When a specific receptor site revealed a sulfate value higher than the sulfate concentration based on its own source origin, this was taken to indicate long-range transport from another source region. The contribution ratio from various source region was calculated. The contribution ratio of dry and wet deposition was higher on the main continent of the East region. Furthermore, the high deposition amounts were identified on the west coast of Korea and the East China Sea.

Terra MODIS is one of the few space-borne sensors currently capable of acquiring radiometric data over the range of view angles. Institute of Industrial Science, University of Tokyo, has been receiving Terra MODIS data at Tokyo since May 2001 and Asian Institute of Technology at Bangkok since May 2001. They can cover whole East Asia and is expected to monitor environmental changes regularly such as deforestation, forest fires, floods and typhoon. Over eight hundred scenes have been archived in the storage system and they occupy 2 TB of disk space so far. In this study, MODIS data processing system on WWW is developed including following functions: spectral subset (250m, 500m, 1000m channels), radiometric correction to radiance, spatial subset of geocoded data as a rectangular area with latitude-longitude grid system in HDF format, generation of a quick look file in JPEG format. Users will be notified just after all the process have finished via e-mail. Using this system enables us to process MODIS data on WWW with a few input parameters and download the processed data by FTP access. An easy to use interface is expected to promote the use of MODIS data. This system is available via the Internet on the following URL from September 1 2002, "http : //webmodis.iis.u-tokyo.ac.jp/".
