The series of forest Fires in Kangwon Province in April, 2000, were one of the mast serious ones in the Kang-won Province in recent years. The fire damaged areas are extensive and this paper investigates the utility of the satellite image data, particularly the RADARSAT SAR data. One of the main objectives of this study included evaluation of potential usefulness of the C-band RADARSAT data in the detection of forest fires in mountainous areas. Among several fire damaged sites, the area near Samchuk (city) was selected as the main study area and mufti-temporal RADARSAT(raw) data were acquired and the processed results were comparatively investigated with the IRS-1c data acquired shortly after the fire. To identify the burnt area from the undamaged background in the optical imagery, supervised classification and NDVI processing were carried out and tested with the IRS-1C data. For this experiment, several sets of raw RADARSAT standard and Fine mode (S4, F3, ascending orbit) data were processed and the final image was formed. In addition to the final image, sigma nought (σ°) was catnputed and compared for the burnt area against the undamaged areas. Because of the steep slopes in the study area and subsequent deviation from the flat surface scattering models, the fire scars in the sigma nought (σ°) image were not apparent. However, fire scars are slightly detected in the difference and ratio images obtained from the signal intensity data acquired at different dates (bath before and after fire). Texture analysis of the image data including the burnt areas were carried out using the Multiplicative Markov Random-Field (MMRF) algorithm. The detection of the fire damaged area from both standard mode and fine mode RADARSAT was not as straightforward as in optical data. However, Previous studies with ERS-1 S_AR and RADARSAT data in Indonesia and in the North American Plains indicate that C-band SAR data provide us with an effective tool for studying the forest fire damages. However, the application of C-band SAR data to the analysis of the forest fire areas requires careful processing of the data with realistic scattering models.

The development of in vitro assays has been recommended to screening and test-ing the potential endocrine disruptors (EDs). These assay systems focus only on identifying thethe thyroid hormone (TH) disruptors. The aim of this study was to evaluate a test system to detectTH disruptors using rat pituitary tumor GH3 cells. The test system is based on the TH-dependentincrease in growth rate. As expected, L-3,5,3-triiodothyronine (T3) markedly induced a morphologicalchange in GH 3 cells from flattened fibroblastic types to rounded or spindle-shaped types. T3 stimu-lated GH3 cell growth in a dose-dependent manner with the maximum growth-stimulating effect9 M. In addition, T3 increased the release of growth hor-mone and prolactin into the medium of the GH3 cells culture. Using this assay system, the TH-dis-rupting activities of bisphenol A (BPA) and its related compounds were examined. BPA,dimethylbisphenol A (DMBPA), and TCI-EP significantly enhanced the growth of GH3 cells in therange of 1 × 10-5M to 1 × 10-6M concentrations. In conclusion, this in vitro assay system might bestandardization before it can be used as a broad-based screening tool.

<돈 끼호떼>에 나타난 속담 속의 현실성

姜泰鎭 대구효성가톨릭대학교 1986 연구논문집 Vol.32 No.1

En la obra, "El ingenioso hidalgo Don Quijote de la Mancha". muchos refranes se han citado por las personas, entre las cuales Sancho Panza es muy distinguido porque el actua como un diccionario de refran. 'Dime con quien andas, decirte he quien,' o 'auando a Roma fueres, haz como vieres,' etc los que son muy populares a nosortros se derivan de esta obra. Primero, vamos a ver los caracteres del refran, Comunmente este es forklorico, humano, que es de los pensamientos y experiencias de los sabios antighuos. En base de estos sentidos, vamos a estudiar las caracteristicas de dos protagonistas: Don Quijote y Sancho Panza comparando los refranes de cada uno. Sobre todo, analicemos los refranes de Don Quijote que se describe como la primera personal quien se esfuerza por armonizar la realidad con su propia idea. en el punto del numero, Don Quijote dice solamente un tercio en comparacion con los refranes de Sancho. Sin embargo, sus refranes nos dicen algunas cosas. Primero, la desconfianza de la sociedad misma; el menciona el peligro social con siguientes refranes. 'Mis arreos son las armas, im descanso, el pelear,' y 'cuando la cabeza duele, todos los miembros duelen.' etc. Segundo, la tendencia del cambio social; en este caso, nuestro protagonista expresa la intencion de que el quiere escaparse rapidamente del ambiente social de aquel tiempo con esto. 'Donde una puerta se cierra, otra se abre.' Tercero, el metodo de existencia del individualismo: en este caso, parece que el autor trata de recuperar el humanismo menospreciado. Por lo tanto, en los dialogos con Sancho, se ven algunos refranes para expresar la situacion de aquel entonces. Y luego, el autor eleva el individualismo con 'Cada uno es artifice de su ventura'. Entonces, vamos a observar los refranes de Sancho Panza. Generalmente, el se expresa como 'un hombre de bien (si es que este titulo se puede dar al que es pobre), pero de muy poca sal en la mollers' en la obra. Pero, en el aspecto de los refranes, el es gran sabio y dice que ''ninguna otro tengo, ni otro caudal alguno, sino refranes y mas refranes.' Los refranes de Sancho se dividen en tres partes, los elementos economicos: el muestra el mammonismo, es decir solamente los ricos puenden gozarse de los derecho humanos segun 'Bien predica quien bien vive'. Y tambien muestra el concepcion de que el presente es mejor que el futuro con 'mas valia un toma que dos te dare.' Segundo, la relacion humana en la sociedad: se ve de vez en caundo una tendencia del oportunismo sobre el estado. Esto dice que en qaquel entonces, se ocurrio frecuentemente el cambio de los estados. Estos ejemplos son 'Juntate a los buenos y seras uno de ellos,' y' Haceos miel y paraos, han moscas,' etc. Tercero, la idea igualitaria de la persona: significa no solo la igualdad con Dios, sino la con reyes. Estos son: 'No ocupa mas pies de tierra el cuerpo del papa que el del sacristan' y 'Al dejar este mundo y meternos la tierra adentro, por tan estrecha senda va el principe como el jornalero'. En conclusion, parece que Don Quijote tiene mas problemas sociales que las cosas individuales. Por esta razon, para solucionar estas problemas, este protagonista que se describe como un idealista mueve continudamente contra la realidad com9o un revolucionario. Al contrario, Sancho Panza se preocapa de sus propios asuntos. Y en vez de combatir contra la situacion real, el quiere ser adoptado a la realidad como un realista.

본 연구는 성장 중인 부정교합 환자의 진단이나 치료계획의 수립,치료방법 및 시기,예후 등을 결정하는데 중요한 판단 지침이 되는 치아 석회화 단계와 경추 및 수완부골 성숙도간의 연관성을 규명하여 개인의 보다 정확하고 효율적인 사춘기 성장 정도를 평가하기 위해 시행하였다. 전신 질환이 없고 교정 치료 경험이 없는 7-16세의 여아 154명,남아 179 명,총 333명의 파노라마 방사선사진,측모 두부규격 방사선사진,수완부 방사선사진을 분석하여 평가하였다. 연구 결과,파노라마 방사선사진의 치아 석회화 단계를 통하여 사춘기 성장 정도를 평가하는 것은 부정교합 환자의 진단 및 치료계획을 수립하는데 임상적으로 유용한 정보를 제공할 것으로 판단되었다. The purpose of this study was to investigate the relationship between the stages of calcification of various teeth and skeletal maturity stages among Korean individuals. The study subjects consisted 154 female and 179 male ranging from 7 years to 16 years of age. A total of 333 hand-wrist, cephalo-lateral and panoramic radiographs were obtained and analyzed. The tooth development of the mandibular canines, first, second premolars, and second molars were assessed according to the Dermijian' s system. Skeletal maturity stages were determined from hand-wrist radiographs by using the SMI system and cephalo-lateral radiographs by using the CVMS, respectively. The results were as follows 1. The mean ages of each stage of skeletal maturity were consistently younger in female subjects. 2. There was a high correlation between skeletal maturity of hand-wrist and cervical vertebrae in the both sexes. 3. There was a high correlation between skeletal maturity and dental calcification stage of mandibular canines, first premolar, second premolars, and second molar. 4. The mandibular second molar was tooth showing the highest correlation. 5. Percent distributions of the relationship between calcification stages of individual teeth and stages of skeletal maturity were obtained in both sexes. In summary, this suggests that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator of the pubertal growth period.
