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.

The Effect of Cultural Factors on Anther Culture in Spring Wheat (Triticum aestivum)

Kang,Tae-Jin,Yang,Deok-Chun 한국자원식물학회 2003 Plant Resources Vol.6 No.2

Effects of shaking, medium consistency and anther density on polyhaploid production in two wheat cultivars, Pavon and Chris, were studied using a modified 85D12 medium. Pavon produced more calli in shaking and more albino plants tban Chris. However, Chris produced threefold more green plants than Pavon in non-shaking treatment. More calli and green plants were derived from non-shaking treatment than those from shaking treatment. Anthers were cultured on both liquid and semi-solid 85D12 media, using two anther densities, 48 and 96 anthers per plate. Although Pavon generally produced more calli and albino plants than Chris, Chris produced more green plants than Pavon. More green plants were derived from semi-solid medium than those from liquid medium. A factor that may affect plant regeneration from anthers is the length of time on initiation medium. Most of the calli for both genotypes were transferred during the first two time periods. Fertility, as measured by seed set, was determined for all surviving regenerated plants. About 24% of Chris and Pavon anther-derived green plants in the experiment of medium consistency and anther density produced seed.

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.

Kang,Tae-Jin,Kim,Se-Young,Rho,Yeong-Deok,Deok-Chun 한국자원식물학회 2003 Plant Resources Vol.6 No.3

The important component for medical effect in ginseng is ginsenoside. Korea Ginseng & Tobacco Research Institute contains approximately 200 lines produced by inbred selection. It is assumed that ginseng lines containing high level of ginsenoside should be included in those lines. Besides, new breeding methods such as cell line selection in vitro and hairy root were recently developed. Therefore, this study was carried out to detect genes related to ginsenoside, and to use it for selection marker to select and distribute lines containing high level of ginsenoside. DNA was extracted from both ginseng roots and hairy roots, and the difference between the line containing high ginsenoside(KG101) and normal ginsenoside(KG103) were analysed. As a result, 28 out of 36 primers showed bands, and many primers showed band difference between ginseng lines. It is considered that the bands should be analysed using DNA sequence comparison to check if those are related to ginsenoside. In case of hairy roots of ginseng, almost no differences were found between two lines.
