The parasitic copepod. Caligus chanos parasitized on labridae fish around MunSum. Cheju Island, have been basically studied form Sep.. 1996 to Aug.. 1997. Parasitic pattern and water temperatures have a close relationship. which is high in June and low form Feb. to Apr.. Fishes of main hosts were Pseudolabrus japonicus and Pteragogus Ragellifer. Parasitic copepods prefer the body and tail of the host to the head, and prefer adult host to juveniles or older one.

The effect of reducing flood magnitudes, flood stages, and flood damage by upstream reservoir regulation are investigated in this study. The analytical procedures which has been established newly, are treated through this study for 7 index stations and same numbr of reaches. The method of this study could be expressed briefly as following procedures. Using stage-frequency relations and the potential damage survey data, damage-frequency relations are established, and from this, average annual flood damages computed. By holding out portions of the floods with various amounts of flood control storage in 6 reservoirs in the basin, routing were made to establish modified stage-frequency relations. From damage frequency relation, average annual damages are computed with and without condition of each control volume. The study result are concluded as follows; (1) The relationtship of corresponding water level between nearby stations are useful tools to adjust error of the data due to observation error and change of the gaging location. (2) The number of records about 10 years could not be applied for the statistical methods of flood frequency analysis. (3) The regional skew factors are recommended to apply flood frequency study by the log-Pearson Type III method. (4) The effect of damage reductions are greatly affectedin accordance with the routed flood. Therefore application of the Typical Tributary Contribution Flood are reasonable for this type of study. (5) In the North Han, effect of damage reduction due to the lacation of control point are gradually increased from upstream to downward until the confluence of North and South Han. (6) In the South Han, control effect are increased from Chungju to Yeoju where the maximum effect are analyzed and then decrease gradually until the confluence. (7) Better hydrologic and topographic combinations for the flood control are existed in South Han to compare with North Han in this study results.

It is important to analyze characteristics of real-time ATM traffic in order to control ATM traffic efficiently. VBR(variable bit rate) traffics such as real-time video traffic and audio traffic are monitored and analyzed based on data obtained from LAN traffic at Cheju National university. ATM traffic characteristics from the measured data are discussed. Cumulative density function(CDF) and traffic generation function (TGF) are obtained from the measured data. The traffic data generated from the TGF and the measured data are compared and the results show that the traffic data generated from the TGF is similar to the measured data. The TGF can be used to design congestion control algorithms, to implement communication protocols, and to develop switching architectures for the ATM network.

Comparison of four species (Prunus yedoensis, P. sargentii, P. pendula for. ascendens, P. serrulata var. quelpaertensis) and one cultivar of P. yedoensis were carried out by comparing their nucleotide sequences from the internal transcribed spacers (ITS) I of nuclear ribosomal DNA (rDNA). The length of the ITS I region was ranged from 229 to 236 base pairs (bp). The G+C contents of ITS I ranged from 58.5 to 60.2%. The value of nucleotide divergence across for four Prunus species and one cultivar ranged from 0.4 to 6%. The pairwise distance between P. pendula for. ascendens and P. yedoensis was 0.004 showing the lowest value among any other pairs. On the other hand, the pairwise distance betwen P. yedoensis and cultivated P. yedoensis was 0.026. The nucleotide analysis based on ITS I sequence was considerably similar to previous studies on the basis of random amplified polymorphic DNA (RAPD).

정용환,한상현,오유성,고미희,고석찬,김문홍,오문유 濟州大學校 基礎科學硏究所 2001 基礎科學硏究 Vol.14 No.2

We analyzed the genetic variation and phylogenetic relationship among fourteen taxa of GenusAbies distributed in Korea using random amplified polymorphic DNA (RAPD) and internal transcribed spacer (ITS) 2 sequences of the nuclear ribosomal DNA (rDNA). RAPDs were used for identification of selected taxa by amplification using single 10-mer primers of arbitrary sequence. Fourteen taxa were clearly classified with 10 arbitrary primers, which generated 102 useful polymorphic bands that were evaluated according to the presence or absence of the fragments of equal size. The genetic distance between A. koreana for. chlorocarpa and A. koreana for. rubrocarpa was 0.127, showing the closest among any other pairs. By comparing the base sequences in the ITS2 region of the nuclear rDNA, genetic relationship was assesed among selected taxa. It showed twenty six sites of point mutation (base substitution) in 243 base pairs (bp) of ITS2 region. The G+C contents of ITS2 region were ranged from 58.3% to 61.7%. The value of nucleotide divergence among selected taxa was ranged from 0.4% to 9.8%. These results showed that RAPD and ITS2 sequence analysis was a useful tool for elucidating phylogenetic relationship and selection of specific marker in Abies species.

Background: Almost previous studies have evaluated the pulmonary impairment in pulmonary function test (PFT) during and after pulmonary tuberculosis (TB). The aim of this study was to evaluate the change of lung function by means of quantifying the lung function in the same individuals both before and after the occurrence pulmonary TB, as well as the different change of lung function according to disease extents based on number of lobes involved on chest computed tomography. Methods: The changes of lung function and predictors from patients with pulmonary TB according to disease extents were evaluated. Localized and advance pulmonary TB was defined as one or less and two or more involvement of lobe by TB, respectively. Results: In total, 41 patients were included. The patients were predominantly male (70%) and old (median age, 63.5 years, IQR, 56.5-69.8 years). The advanced TB group had a median decline in FEV1 of 0.3L (0.2-0.6) and the localized TB group had a median decline of 0.1L (0.0-0.2) (△FEV1, % predicted, 14.5% (7.3-25.1) vs. 5.6% (2.8-9.7)). For FVC, the median decline in the advanced TB group was 0.45L (0.2-0.5) compared with 0.2L (0.0-0.3) in the localized TB group (△FVC, % predicted, 11.5% (8.9-25.6) vs. 4.1% (1.4-8.9). In multivariate analysis, remarkable lung function decline of FEV1 and FVC was independently associated with advanced TB. Conclusions: The localized pulmonary TB does not lead to significant pulmonary impairment. However, further lung function decline occurred in cases of advanced pulmonary TB. In addition, advanced pulmonary TB was independently associated with remarkable lung function decline in FEV1 and FVC after pulmonary TB.

Background: The aim of this study was to evaluate the trend in the rates of drug-resistant tuberculosis (TB) over time, as well as the difference in the drug-resistance pattern between pulmonary TB and extrapulmonary TB at a private referral center in South Korea. Methods: All patients with TB confirmed by culture from 2006 to 2013 were included in this study. Results: In total, 1745 patients were included: 1407 (80.6%) were new cases, and 338 (19.3%) were previously treated cases; 1610(92.2%) were pulmonary TB, and 135(7.7%) were extrapulmonary TB. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) TB was detected in 5.7% and 2.0% of new cases and in 20.1% and 8.6% of previously treated cases, respectively. The trend of the analysis of change in the drug-resistance pattern in all TB cases during the study period did not show a remarkable decrease in the rate of MDR TB. In previously treated cases, the rate of MDR and XDR TB showed a significant decreasing trend. MDR TB was detected to a lower extent in extrapulmonary TB compared with pulmonary TB patients. Conclusions: The drug-resistance rate of TB, especially MDR TB, remains high at a private referral hospital, and the trend of the drug-resistance rate did not show a significant decrease from 2006 to 2013. This underscores the necessity to perform a national survey regarding the prevalence of drug-resistant TB for the purpose of obtaining the most accurate and current drug resistance status in South Korea, including the private sector.
