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.

( Chung Hoon Kim ),( Jei Won Moon ),( Jin Young Min ),( Jun Woo Ahn ),( Sung Hoon Kim ),( Hee Dong Chae ),( Byung Moon Kang1 ) 대한산부인과학회 2014 대한산부인과학회 학술대회 Vol.100 No.-

목적: To compare the effect of long-acting recombinant FSH (rFSH), corifollitropin alfa with daily rFSH administered during 1st 7days of controlled ovarian stimulation (COS) using GnRH antagonist multiple dose protocol (MDP) in poor responders undergoing IVF/intracytoplasmic sperm injection (ICSI). 방법: In this prospective randomized study total of 90 poor responders who were scheduled for IVF/ICSI were enrolled and divided into the corifollitropin alfa group (study group) or the daily rFSH group (control group). The diagnosis of poor responder was based on the Bologna criteria of the 2011 ESHRE consensus. In all subjects, GnRH antagonist MDP was used for COS. 결과: There were no differences in patients` characteristics between the two groups. Duration of COS was comparable between the study and control groups. The numbers of oocytes retrieved and grade I or II embryos were also similar in the two groups. However, the number of mature oocytes was higher in the study group with a borderline significance (p< .07) and the ratio of mature oocytes among total oocytes retrieved was significantly higher in the study group of 78.6 ± 13.0%, compared with 61.2 ± 16.0% in control group (p< .001). There were no differences in the clinical pregnancy rate per cycle initiated, embryo implantation rate and miscarriage rate between the two groups. 결론: Corifollitropin alfa is at least as effective as daily rFSH treatment for COS using GnRH antagonist MDP, and may improve the synchrony of follicular development in poor responders undergoing IVF/ICSI. Therefore, corifollitropin alfa may be a feasible, patient-friendly alternative for poor responders.

Objective. Productivity loss was compared by 3-stage of disease activity and associations between higher disease activity and high productivity loss were identified. Methods. Data were extracted from Rheumatoid Arthritis (RA) Patient-reported Outcomes Research, which enrolled 2,000 RA patients (>20-year) on disease-modifying-antirheumatic-drugs (DMARDs) (≥ 6-month) from December 2012 to June 2013. This included 1,457 RA patients with the disease activity score (DAS-28-ESR) in their medical charts. Productivity loss in time and indirect cost was estimated using The World Health Organization Health and Work Performance Questionnaire (HPQ). Baseline characteristics and productivity loss outcomes were compared according to DAS-28-ESR groups. Results. 84.4% were females, 54.2% had low DAS-28-ESR (<3.2), and 38.2% and 7.6% had moderate (3.2∼5.1) and high DAS-28-ESR (>5.1). Patients with moderate to high DAS-28-ESR had higher lost productivity time (LPT) and monthly costs of LPT than those with low DAS-28-ESR (time in hours: 110.0±58.4 vs. 132.4±57.2 vs. 71.5±52.0, p<0.0001; monthly costs of LPT in 1,000 Korean won: 1,097±607 vs. 1,302±554 vs. 741±531, p<0.0001). Multiple regression analyses revealed significant associations with high LPT in high (adjusted odds ratio [OR]=3.87, 95% confidence interval [CI]: 2.18∼6.87) and moderate DAS-28-ESR (adjusted OR=1.88, 95% CI: 1.41∼2.52) compared to low DAS-28-ESR. In addition, positive associations with high monthly costs of LPT were observed in high (adjusted OR=3.45, 95% CI: 1.98∼5.99) and moderate DAS-28-ESR (adjusted OR=1.93, 95% CI: 1.43∼2.54) compared to low DAS-28-ESR. Conclusion. Timely therapeutic strategies should be taken into consideration given that the RA patients with moderate to high DAS-28-ESR showed strong associations with high productivity loss for effective management of RA.

We estimate the economic benefit of weather modification (precipitation enhancement and fog dissipation) by assuming its operation for the considered regions. Based on the statistical data, the economic benefit of the virtually operational precipitation enhancement experiments for the Andong and Imha basins, where the natural precipitation is relatively lack in South Korea, is calculated 348 for the water resources, 22,458 for forest fire prevention, and 28,458 million won/year for the drought relief. The benefit of the fog dissipation operation for the Incheon International Airport is estimated 7,365 million won/year for the flight delay due to fog. The calculated ratio of benefit to cost for precipitation enhancement operation for the basins is 14.07, which is comparable to that conducted in other countries.

In Korea, six mealybug species have been reported on pears. This study investigated the occurrence of mealybugs in 19 pear orchards from 2013 to 2014. Two species, Crisicoccus matsumotoi (Siraiwa) (Hemiptera: Pseudococcidae) and Pseudococcus comstocki (Kuwana) were mainly found. The dominant species was C. matsumotoi identified on 73% of infested fruit. Toxicities of 14 registered insecticides (7 single formulations and 7 mixed formulations) commonly used to control P. comstocki were evaluated to C. matsumotoi nymphs and adults at the recommended concentration. As a results, all insecticides exhibited strong insecticidal activity with 100% mortality of both nymphs and adults. These results indicate that the 14 insecticides can be used in control for C. matsumotoi in field.

생균제 개발을 위하여 한 종류의 유산균을 유아 분변으로부터 분리하였다. 이 세균을 16s rDNA 염기서열 분석을 통하여 확인해 본 결과 Lactobacillus rhamnosus로 동정되었다. 이 유산균은 호기성 조건에서도 잘 자라는 통성 혐기성 세균이었다. 이 유산균은 MRS 배지에 48 시간 액체 배양하였을 때 배양액의 pH를 2.4까지 낮추는 것을 확인 하였다. 이 유산균은 6 종의 병원성 세균, L. monocytogenes, S. aureus, P. aeruginosa, V. parahaemolyticus, S. typhimurium, and E. coli O157의 생육을 저해하는 것을 확인하였다. 이 유산균을 시판 중인 닭 사료에 섞어 먹인 후 분변의 악취를 조사하였을 때, 분변의 악취 중 약 80 %를 차지하는 황화수소는 대조구 보다 50 %가 감소하였고, 암모니아는 상대적으로 함유된 양은 적었지만 대조구 보다 70 %가 감소하였음을 확인할 수 있었다. 유산균 급이구와 대조구의 외형은 변화가 없었으며, 달걀 무게에 있어서 먹인 닭의 달걀이 평균 5 g 정도 무거워진 것을 확인 할 수 있었다. To develop probiotics, a kind of Lactobacillus sp. was isolated from infant feces. The bacterium was identified as Lactobacillus rhamnosus through 16S rDNA sequence analysis. The strain was a facultative anaerobe which grew better in aerobic conditions. The bacterium lowered the pH of the culture solution down to 2.4 during 48 hr in the MRS medium. The strain inhibited the growth of 6 pathogens - S. aureus, L. monocytogens, S. typhimurium, E. coli O-157, V. parahaemolyticus and P. aeruginosa. When the Lactobacillus were fed to chickens, along with commercial feed, for one month, amounts of H₂S and NH₃ in the feces of the chicken decreased to 50% and 70%, respectively, compared to those of control group chickens. Amounts of other bad smells such as (CH₃)SH, (CH₃)₂S and (CH₃)₂S₂ were not much different in the Lactobacillus-fed chickens compared to the control group. On the other hand, egg weights of the chickens fed Lactobacillus were higher by about 5±1 g than those in the control group.
