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.

Background: Plasma glucagon in sepsis has scarcely studied. We tried to identify whether glucagon levels were associated with disease severity and mortality in patients with severe sepsis or septic shock. Methods: We evaluated patients with severe sepsis or septic shock admitted to ICU of the university-affiliated hospital in Korea. Plasma levels of glucagon were measured in a total 112 patients (57 survivors and 55 non-survivors) with severe sepsis or septic shock. Results: Compared with the survivors, patients who died in 28 days had significantly higher levels of glucagon on day 0 (admission day), 1, 3, and 7. Glucagon levels were correlated with severity scores (SOFA and APACHE-II). Multivariate analysis identified glucagon levels, presence of septic shock as independent predictors of the overall 28-day mortality rate. Receiver operating characteristic analysis showed that the area under curve of glucagon levels to predict 28-day survival was 0.63 (95% CI=0.52-0.73; P=0.021) as similar as APACHE II. Conclusions: Glucagon levels are related to poor prognosis in patients with severe sepsis.Background: Plasma glucagon in sepsis has scarcely studied.

This study examined the prevalence of oral microbes in the saliva of oncological patients and healthy subjects. PCR was used to assess the frequency of oral microbes including 3 cariogenic bacteria, 5 periodontopathic bacteria and 4 Candida species in the saliva of 104 oncological patients and 52 healthy subjects. Among these microorganims, Streptococcus mutans, Fusobacterium nucleatum and Candida albicans were most frequently detected in both groups. There were no significant differences in the prevalence of cariogenic bacteria between the patient and healthy groups, whereas significant differences in the frequency of Porphyromonas gingivalis and Tannerella forsythia were observed between the two groups (p < 0.05). The prevalence of all five periodontopathogens was higher in the healthy group than in the patient group. The prevalence of C. albicans in patients was significantly higher than that of healthy group (p < 0.05). In conclusion, there were significant differences in the prevalence of P. gingivalis, T. forsythia and C. albicans between the oncological patient group and healthy group.

Effect of Pleurotus cornucopiae and Safflower Oil extract on osteoblast activity of rats

Kang Hyo Lee,Sang-won Lee,Chan-Hum Park,Eun-Suk Lee,Ji Yeon Lee,Won-sik Kong,Donghwi Kim,Young-Ock Kim 한국버섯학회 2017 버섯 Vol.21 No.1

To determine the medicinal properties of Pleurotus cornucopiae and Safflower Oil (PS), the osteoblast effect was investigated. PS can prevent estrogen deficiency-induced bone loss. It was taken the measurements of biochemical factors such as serum osteocalcin, alkaline phosphatase, IGF-1, and bone status. Forty adult female Sprague-Dawley rats were randomly assigned to four equal groups for 12 weeks of treatment: (1) sham operation (SHAM) + vehicle; (2) ovariectomy (OVX) + vehicle; (3) OVX + 17β-estradiol (25 μg/kg); (4) OVX + PS (300 mg/kg/d, PO). At the end of the experiment, bone turnover, and trabecular microarchitecture were assessed by micro-computed tomography (micro-CT), and histopathology, respectively. Ovariectomized rats experienced remarkable increases in global volumetric bone density, and trabecular microarchitecture deterioration. These OVX-induced pathological changes are reversible in that most of them could be mostly corrected upon 17β-estradiol treatment. PNS treatment significantly prevented bone mass loss and microarchitecture deterioration. Moreover, PS enhanced osteoblast activity but suppressed osteoclast turnover, as evidenced by decreased levels of serum C-terminal telopeptides of type I collagen and elevated levels of alkaline phosphatase. PS mitigates estrogen deficiency-induced deterioration of trabecular microarchitecture.

Formation of Abnormal Structures and Their Effects on the Ductility of Eutectoid Steel

Kang-Suk An,Shin Woong Jeong,Hyeong Jun Bea,Won Jong Nam 대한금속·재료학회 2016 METALS AND MATERIALS International Vol.22 No.6

The formation of abnormal structures and their effects on reduction of area (RA) were investigated in eutectoidsteels transformed at different temperatures ranging from 560 °C-650 °C. The occurrence of abnormalstructures, such as upper bainite, degenerate pearlite, free ferrite, and grain boundary cementite, was confirmed. The volume fraction of upper bainite and degenerate pearlite decreased on increasing the transformationtemperature, while the amount of free ferrite increased. As the transformation temperature increased, RAincreased, reached a maximum, and then decreased, while the tensile strength continuously decreased. The crackformations during the tensile test could be classified into three types: tearing, shear cracking, and void formation/coalescence. The decrease of the ductility at low transformation temperatures was attributed to theincreased amount of upper bainite and degenerate pearlite, since the formation of cracks occurred by tearinginterfaces or by void formation at abnormal structures during the tensile test. Meanwhile, the decrease inRA at high transformation temperatures was attributed to the occurrence of shear cracking rather than thepresence of abnormal structures.
