The propose of this study is to survey the revetments installed in Gangwon Province for identifying their characteristics. The survey showed that in eastern Gangwon Province, gabion, retaining wall and concrete blocks took about 63% or more, and in western Gangwon Province, dry wall, gabion and retaining wall, 68% or more. Gabion and dry wall had better vegetation coverage in western Gangwon Province than in eastern Gangwon Province. That is thought to be due to slope of river and under-water frequency.

A scan velocity modulation(SVM) technique has been widely used for compensating the deterioration of picture quality due to the beam profile effect of the color picture tube(CPT). In conventional SVM system the so-called linear SVM method has been employed, whose modulation velocity is linearly proportional to the variation in the video signal amplitude. However, the effect of picture quality improvement is irregular with video signal amplitude in the linear SVM. In this paper we report a theoretical analysis of the SVM effect on the spatial brightness distribution of CPT according to the variations in luminance signal amplitude and differentiation circuit characteristic. We also propose a nonlinear SVM method based on the results of the theoretical analysis for optimum picture quality improvements. In computer simulation we confirmed uniform improvements in picture quality by the SVM of nonlinear amplitude transfer characteristic.

Edible flower means a flower that is good to eat is subject to either cooking or appetizing. In general, people eat edible flower as raw so that the loss of vitamin and inorganic are minimal. Edible flower is usually utilized as salad material or aromatic, decoration for jelly or cake and solid stuff in soup. Thus, decorating food by edible flower improves flavor, fragrance and appetite. Edible flower serves various purposes both east and west. In Korea, Edible flower is mainly subject to soup, cooked potherbs, frying, tea stuff, brewing and etc, whereas in Japan, its various usage covers cooked potherbs, pickle, sliced raw fish, frying, salad, jelly and decoration. On the other hand, Edible flower is used as numerous salad and tea stuff, condiment, roasting, meat, sweets and desserts in Western Hemisphere.

Condylar hyperplasia is a self-limiting condition characterized by a slowly progressing, enlargement of the mandible that results in facial asymmetry and a crossbite malocclusion. The facial asymmetry, open bite or crossbite, and radiographic evidence of an enlarged condyle confirm the diagnosis of condylar hyperplasia. The etiology of the condition is unknown. This condition usually first becomes apparent during the second decade of life, when one condyle continues to grow while the other is no longer active. Radiographically, the condyle may appear enlarged or the neck of the condyle may be elongated or both may occur, Sometimes, however, no radiographically demonstrable condylar abnormality will be noted. Surgical correction with subcondylar osteotomy is the treatment of choice. We have observed two cases of condylar hyperplasia occurred in the mandibular condyle of 24-year-old and 35-year-old women. We obtained that two cases were shown the followed results; 1. Clinically, both cases was unilaterally developed on C/C area, with temporomandibular disorders and pain, facial asymmetry and malocclusion. 2. Radiographically, hyperplastic mass confined to the condyle. 3. Histopathologically, these cases shown increased hypertrophic region in parts, and lamellated bone with irregular trabeculae.

Patients with spontaneous pontine hemorrhage very often develop setvere disturbances of consciousness,pupilary abnormalities, respiratory and motor. They have high mortality rate. Therefore, I analyzed the correlation between the Glasgow outcome scale(GOS)and clincial manifestations or computed tomographic(CT)findings in 48 patients with spontaneous pontine hemorrhage to clarify factors predicting the prognosis. I examined 48 Patients with spontaneous pontine hemorrhage; 33 males and 15 females, age 54.6±8.99(mean±S.D.;range 39 to 68)brought to our hospital between January 1995 and December 1999, retrospectively. Correlations between the clinical manifestations, CT findings and the GOS was assessed with multivariate regression analysis. The results were as follow: 1) Patients with the pontine hemorrhage were of 8.8% in those with intracerebral hemorrhage. The ratio of male and female was 33 to 15. The incidence of age is eqial to 40,50 and 60. Total mortality was 41.6%. 2) The poor prognostic factor were that; Glasgow coma scale(GCS)3∼8, irregular respiration. pupilary abnormality, quadriplegia, Brain CT typeⅠ(massive), hydrocephalus, extrapontine extension, Intraventricular hemorrhage(IVH). These clinical analysis should be useful in determining the level of care and future resuscitative efforts.

The Multiple Hypotheses Tracking (MHT) algorithm has been shown to be one of the most cost- effective estimation schemes for hybrid systems. Its performance, however, could only evaluated via expensive Monte-Carlo simulations. An effective hybrid approach to the performance evaluation without recourse to simulations is presented here. This approach is based on a scenario-conditional performance measure of hybrid nature in the sense that it is a continuous-valued function of a discrete-valued random sequence. The performance measure is calculated efficiently in an off-line recursion.

The authors have made and attempt to examine the transition of the leading causes of death in Korea recently since 1984 by analytically reviewing the annual statistical data on the causes of death for the latest ten years reported mainly from the National Statistical Office and other informative materials. The results were summarized as follows: 1. After the inverting period of the 1970s and early 1980s changing remarkably from the communicable to the non-communicable disease, the leading causes of death were changed to the chronic degenerative diseases such as circulatory disease and malignant neoplasms recently. 2. With the particularly increasing deaths due to the unintentional accidents since the mid-1980s, circulatory disease, malignant neoplasms, and accidents became the three leading causes of death, and accounted for about 66.5 percent of the total deaths in 1993. 3. Concerning the sex-specific leading causes of death, currently they were malignant neoplasms, accidents, cerebrovascular disease, chronic liver disease, and heart disease in males, and cerebrovascuar disease, malignant neoplasms, heart disease, accidents, and hypertensive disease, malignant neoplasms, heart disease, accidents, and hypertensive disease in females in that order respectively. 4. As to the leading causes of death by the age-groups, they were congenital anomaly and infectious disease at infantile age; accidents and unintentional injury at ages 1-39year: malignant neoplasms, circulatory disease, and chronic degenerative disease at ages 40-69years; and circulatory disease, senility and other chronic degenerative disease at ages 70 and over respectively. 5. In reviewing the transition of the leading causes of death, communicable diseases formidably prevailed for the past decades were rapidly decreased recently, and chronic degenerative disease, So-called, "Chronic Illness" such as circulatory disease, malignant neoplasms, and chronic pulmonary disease are in tendency of continuous increase year by year. Although chronic liter disease seems to be stationary in incidence now-a-days, additionally, its level of death is still relatively high. And the death rates due to all kinds of accidents are remarkably increasing. Overall, accidents and unintentional injuries were the third leading cause of death and accounted for about 15 percent of the total deaths.

This study shows data collection and data processing needed for park management using GIS and satellite remote sensing. Digital topographic maps, geological maps and satellite imagery covering Kumoh Mt. Province Park selected as the study area were utilized for analysis of landform and land surface space. Thematic maps and statistic data associated to elevation, slope and aspect were obtained through extracting DEMs from contour layers of digital topographic maps. The other spatial analysis associated to geology and vecter data overlaid on DEM were conducted. Also a landcover map and a NDVI map were extracted through processing of Landsat TM satellite imagery. It is expected that these technologies can be utilized as the tool of pre-assessment for the suitable land use that takes the middle of development and preservation especially in natural parks.

Purpose : To assess the methods for the clinical evaluation of the longitudinal bone changes after implantation of tooth ash-plaster mixture into the defect area of human jaws. Materials and methods : Tooth ash-plaster mixtures were implanted into the defects of 8 human jaws. 48 intraoral radiograms taken with copper step wedge as reference at soon, 1st, 2nd, 4th, and 6th week after implantation on mixture were used. X-ray raking was standardized by using Rinn XCP device customized directly to the individual dentition with resin bite block. The images inputted by Quick scanner were digitized and analyzed by NIH image program. Cu-equivalent values were measured at the implanted sites from the periodic digital images. Analysis was performed by the bidirectional subtraction with color enhancement and the surface plot of resliced contiguous image. The obtained results by the two methods were compared with Cu-equivalent value changes. Results : The average determination coefficient of Cu-equivalent equations was 0.9988 and the coefficient of variation of measured Cu values ranged from 0.08∼0.10. The coefficient of variation of Cu-equivalent values measured at the areas of the mixture and the bone by the conversion equation ranged from 0.06∼0.09. The analyzed results by the bidirectional subtraction with color enhancement were coincident with the changes of Cu-equivalent values. The surface plot of the resliced contiguous image showed the three dimensional view of the longtudinal bone changes on one image and also coincident with Cu-equivalent value changes after implantation. Conclusion : The bidirectional subtraction with color enhancement and the surface plot of the resliced contiguous image was very effective and reasonable to analyze clinically and qualitatively the longitudinal bone change. These methods are expected to be applicable to the non-destructive test in other fields.(J Korean Oral Maxillofac Radiol 1999;29:423-434)
