  • Purpose : Many gene polymorphisms are associated with coronary artery abnormalities in Kawasaki disease. Catechol-O- methyltransferase (COMT) plays an important role in the metabolism of catecholamines, catechol estrogen, and catechol drugs. Polymorphisms of the COMT gene are reported to be associated with myocardial infarction and coronary artery abnormalities. The aim of this study was to evaluate the relationship between COMT gene polymorphisms and coronary artery abnormalities in Kawasaki disease patients. Methods : One hundred and one Korean children with Kawasaki disease and 306 healthy Korean control subjects were enrolled in this study. The polymorphisms of the COMT gene were analyzed by direct sequencing. Results : There were no differences in the genotype and allelic frequency of the rs4680 and rs769224 polymorphic sites between Kawasaki disease and control subjects. Further, no significant difference was found in the rs4680 polymorphism between patients with coronary artery abnormalities and patients without coronary artery abnormalities (codominant P=0.32, dominant P=0.74, recessive P=0.13). However, the distribution of the rs769224 polymorphism was significantly different between patients with coronary artery abnormalities and patients without coronary artery abnormalities (codominant P= 0.0077, dominant P=0.0021, recessive P=0.16). Conclusion : Our results indicate that the polymorphisms of the rs769224 gene might be related to the development of coronary artery abnormalities in Kawasaki disease.

  • The Purpose of this study is to find the levels of keeping financial records among Korean households and to reveal the effect of keeping financial records on financial soundness of households. The 2014 Consumer Empowerment Index of the Korean consumer agency, which includes the surveyed results of 1,000 individuals, was analyzed as a secondary dataset. As a result, the following findings emerged during the study. First, 25.9% of consumers replied that they were keeping financial records. Factors associated with keeping financial records were gender and income. Women were more likely to keep financial records than men. Also, income had significant effects on keeping financial records. Second, levels of meeting percentages of financial ratios were highest in the debt to income ratio, which was 81.5%, and lowest in the investment ratio, which was 14.5%. Furthermore, 52.6% met the savings ratio, 40.6% met the emergency funds ratio, 24.6% met the retirement savings ratio. Meeting a percentage of the savings ratio did not fluctuated for 16 years, although the debt to income ratio has decreased around 15% since 1998. Third, keeping a household account book had signigicant influences on meeting percentages of financial ratios. Magnitudes of effects ranged between 1.4-1.8 odds, which were as much as the income effects. In summary, effects of keeping financial records were evidenced in this study. It is suggested that the importance of keeping financial records should be stressed in financial education and counseling programs.

  • Consumption of a diet consistent with dietary guidelines is believed to have a beneficial effect on the prevention of chronic diseases and the promotion of general health. This study was conducted to explore the relationship between adherence to the Korean Food Guidance System (KFGS), which was based on the 2010 revised KDRIs, and the risk of metabolic abnormalities. Five hundred and ninety-six Korean adults between 30 and 59 years of age were recruited by advertisement to the Bundang Jesaeng General Hospital (BJGH), and those not taking regular medications and without diagnoses of fulminant disease were included. Data were collected on anthropometric measurements, diagnostic parameters for metabolic syndrome (MetS), and 3-day dietary intakes from individuals in the study. The number of servings consumed from each food group was compared to the KFGS recommended servings for each of the 6 food groups. Poor adherence to the recommendations for servings of milk and dairy products (OR: 2.038, 1.128-3.682) was associated with a higher risk of MetS, and poor adherence to the guidelines for fruit consumption (OR: 1.849, 1.027-3.329) was associated with a higher risk for the existence an elevated waist circumference. Conversely, the consumption of meat, fish, eggs, and beans above the recommended number of servings was associated with a lower risk of having an elevated waist circumference (OR: 0.523, 0.288-0.950), and the consumption of vegetables above the recommended number of servings was associated with a reduced risk of having elevated fasting glucose (OR: 0.533, 0.298-0.954). These results suggest that adherence to the KFGS guidelines helps to prevent the development of MetS, but this association needs to be confirmed by prospective studies.

  • 1. Objectives The purpose of this study was to investigate the correlation of Metabolic syndrome(MetS) and Intima-media thickness(IMT) of common carotid artery with Sasang constitution. 2. Methods 197 subjects who had taken health examinations and diagnosis of Sasang constitution from Jan 1, 2006 to Dec 31, 2006 at East-west health examination center of Kyung-Hee medical center were included and underwent B-mode ultrasonography for measurement of intima-media thickness of common carotid arteries. MetS was defined by the criteria of the criteria of the National Cholesterol Education Program Adult Treatment Panel III. 3. Results and Conclusions Mean intima-media thickness of common carotid artery was significantly higher in subjects with MetS compared with control subjects($0.070{\pm}0.017$ vs $0.063{\pm}0.014cm$) and a significant trend towards increased IMT was observed with increasing numbers of metabolic syndrome components(r=0.331, p=0.000). After adjustment for age and sex, IMT of common carotid arteries was significantly different among three constitutional groups (Soyangin:$0.065{\pm}0.015cm$, Taeumin:$0.068{\pm}0.016cm$, Soeumin:$0.056{\pm}0.010cm$), however, after adjustment for age, sex and existence of metabolic syndrome, there was no significant different. But, factor of Taeumin was the effective determinant of the increase of mean IMT of common carotid arteries.

  • This study was conducted to investigate changes in blood properties of high potassium (HK) phenotype Jindo dogs (15kg$\pm$2kg) after daily oral administration with water celery extracts (10 ml/kg) for 7 days. Blood samples were collected for three days in a row before administration of water celery extracts. After water celery extracts administration, blood samples were collected at 3h, 6h, 9h and then on daily basis until day 10 post administration (PA). At day 15, final sample was collected. Blood samples were analyzed on the basis of red blood cell (RBC), white blood cell (WBC), packed cell volume (PCV), hemoglobin (Hb) concentration, mean corpuscular volume(MCV), mean corpuscular hemoglobin concentration(MCHC), gluthathione concentration(GSH) and met-hemoglobin(Met-Hb) concentration. The significant changes (p<0.01, p<0.05) of RBCs were shown at 3 h to day 5, and days 7 and 9 after administration. PCV values were decreased form 3 h to day 10 after administration. Mean Hb concentration showed significant increase as 3 h to day 3, and day 6 to day 9 after administration. The significant changes (p<0.05) of WBCs were shown at 9 h and day 1 after administration. The increased numbers of MCV were detected at days 6 to 9 after administration (p<0.05, p<0.01). The significant changes of MCHC were shown at 9h and day 1 after administration. The significant increases (p<0.01, p<0.05) of GSH concentration were detected at days 1, 6 and 7 after administration. In Met-Hb concentration, the significant increases (p<0.05) occurred at only 9h and day 7 after administration, The significant increases (p<0.01, p<0.05) of reticulocyte were detected at days 2, 4, 5, 6 and 7. Data from blood samples collected at day 15 after administration showed that all of blood analysis results returned to normal level, compared to controls.

  • Structurally, herboxidiene contains the tetrahydropyran acetic acid moiety and a side chain including a conjugated diene, and has been isolated from Streptomyces chromofuscus ATCC 49982. Its production was significantly elevated nearly 13.5-fold (0.74 g/l) in a medium supplemented with glycerol (medium No. 6A6), and was more efficacious (1.08 g/l; 19.8-fold) in fed-batch fermentation at 36 h in medium No. 6A6, from Streptomyces chromofuscus. For further enhancement, regulatory genes metK1-sp and afsR-sp from Streptomyces peucetius were overexpressed using an expression vector, pIBR25, and similarly ACCase from Streptomyces coelicolor and two genes, metK1-sp and afsR-sp, were also overexpressed using an integration vector, pSET152, under the control of the strong $ermE^*$ promoter in Streptomyces chromofuscus. Only the recombinant strains S. chromofuscus SIBR, S. chromofuscus GIBR, and S. chromofuscus AFS produced more herboxidiene than the parental strain in optimized medium No. 6A6 with an increment of 1.32-fold (0.976 g/l), 3.85-fold (2.849 g/l), and 1.7-fold(1.258 g/l) respectively.

  • There are 4 types of equipment in diagnostic radiography. These are single phase, three phase, inverter type and condenser type X-ray generators. It is very confusing to make an adequate exposure factor and to know the usage of different type of X-ray generators. In this experiment, I explored a comparative study of outputs in 4 different type of X-ray units. I expect that this experiment could be helpful for manufacturer to make both the X-ray equipment better, In terms of Ideal exposure factors, thereby reducing the patient dose. Experimental results are as follow : 1) X-ray output The ratio of X-ray output of single, three phase and inverter type of X-ray generator was 1 : 1.6 : 2 without absorber and 1 : 2 : 2.6 with 20 mm aluminium absorber. 2) Beam quality The X-ray beam quality of single phase generator was proved to be softer than three phase and inverter type of generators by 0.4 mmAL and 0.55 mmAl HVL respectively. 3) Reproducibility Linearity of X-ray output Retroducibility of X-ray output met the regulation below CV 0.05 and linearity also met the regulation below 0.1 in 4 types of diagnostic X-ray generators. 4) The comparison of incident dose Three phase X-ray generator was 20% higher than two other X-ray generators in radiation dose to make same film density.

  • An experimental Chung-Kook-Jang was prepared using the strain Bacillus subtilis sp. isolated by the author Samples were taken in 12 hrs interval during the fermentation and the oligopeptides were separated by the method of molecular sieving using the ion exchange resin column of Dowex-50. Only the X-16 fraction of oligopeptides was taken and the components of oligopeptides were developed in two dimensional thin layer chromatograms. The each peptide spot was eluted and each peptide was isolated. The pattern and kinds of amino acids, and N and C-terminal amino acids were studied. Fourteen different oligopeptides could be detected by the two dimensional thin layer chromatography, all of which were consisted of $4{\sim}9$ kinds of amino acids. No dipeptides and no tripeptides could be found. The N and C-terminal amino acids and the residual component amino acids of all these 14 peptides could be summarized as the follows. [P]-I. Pro (Cys Ala Asp Trp Ile Val) Glu [P]-II. Val (His Arg Glu Thr Ala Met) Asp [P]-III. Glu (Cys Lys Asp Thr Met) Ala [P]-IV. Glu(His Ser Ala) Met) [P]-V. Ile (Cys Asp Arg Gly Pro T.p Phe) His [P]-VI.

  • This study classified UAV image-based physical spatial types for parks in urban areas of Changwon City and analyzed thermal comfort characteristics according to physical spatial types by comparing them with ENVI-met thermal comfort results. Physical spatial types were classified into four types according to UAV-based NDVI and SVF characteristics. As a result of ENVI-met thermal comfort, the TMRT difference between the tree-dense area and other areas was up to 30℃ or more, and it was 19. 6℃ at 16:00, which was the largest during the afternoon. As a result of analyzing UAV-based physical spatial types and thermal comfort characteristics by time period, it was confirmed that the physical spatial types with high NDVI and high SVF showed a similar to thermal comfort change patterns by time when using UAV, and the physical spatial types with dense trees and artificial structures showed a low correlation to thermal comfort change patterns by time when using UAV. In conclusion, the possibility of identifying the distribution of thermal comfort based on UAV images was confirmed for the spatial type consisting of open and vegetation, and the area adjacent to the trees was found to be more thermally pleasant than the open area. Therefore, in the urban planning stage, it is necessary to create an open space in consideration of natural covering materials such as grass and trees, and when using artificial covering materials, it is judged that spatial planning should be done considering the proximity to trees and buildings. In the future, it is judged that it will be possible to quickly and accurately identify urban climate phenomena and establish urban planning considering thermal comfort through ground LIDAR and In-situ measurement-based UAV image correction.
