  • This report describes a case of foot and mouth disease (FMD) in farm-raised Sika deer. FMD serotype A occurred in six cattle farms in January 2010 since the outbreak of pig cases 2002 in South Korea. In addition to the six cattle farms where the disease occurred during January, positive reactions to FMD antibodies were found in two heads of deer on March at a deer farm in serological tests intended to lift the movement restriction of the susceptible animals imposed within risk zone. In the specimens collected from 12 heads for confirmatory tests in the same farm, no virus was detected in antigen tests and neutralising antibody titers in all raising deer in the farm were relatively high. So it seems likely that the animals had been infected with FMD at least one month earlier when they were found.

  • The purpose of this research is to examine the specificity of grids to define the characteristics of clothes styles in the Joseon Dynasty period. The significance of examining of the specificity of grids is to find out arbitrary types of the features of grids involved in structuring the Jeogori in the Joseon Dynasty period one by one. The Visual Linguistic Theory was introduced as a methodological tool to exquisitely analyze the characteristics of grids in deep structures of Jeogori in the Joseon Dynasty period. This theory strives to examine sample distribution, the distribution of samples by quality and the distribution of the types of ploidy features. Through the examination, the results are as follows. The grid systems of the Jeogori consisted of diverse proportion systems reaching 86 cases, that is, sequence systems composed of multi-functional, multi-combined bodies. Most ornamental grids had feature angles distributed in a range of $2-20^{\circ}$ that showed a common preference for low sloped diagonal lines or small curvature. Although the preference for certain feature angles were prominent, the feature angles that were used were generally distributed evenly among diverse feature angles to show the characteristics of separation. Therefore, Jeogori makers in the Joseon Dynasty period can be considered as having experimented with many proportion systems to show their aesthetics. In conclusion, based on the results of the examination of feature distributions and related methods to allocate ploidy features, O-type accounted for 66% and thus it was identified that the Jeogori was characterized by O-type. Therefore, it was identified that the characteristic of the Jeogori in the Joseon Dynasty period consisted of O-type fractal structures which are formative structures unique to our nation.

  • Multiple emulsions, called multiphase emulsions, include water-in-oil-in-water (W/O/W) type and oil-in-water-in-oil (O/W/O) type emulsions. In cosmetic industry, they are used to stabilize active ingredients but the applicability of the multiple emulsions is limited because of low stability and difficulty of manufacturing. In this study, we investigated a two-step emulsification process for a W/O/W type emulsion. We also investigated the change of stability using different emulsifiers and oil polarity. The results suggested that polyglyceryl-10 stearate, as a main emulsifier, played an important role in the stability and the formation of the multiple emulsions.

  • Objectives: The objective of this study was to investigate analysis of bone mineral density according to Women with low back pain women. Methods: The data were collected from women who visited Physical Examination Center of a Catholic university hospital located in Daegu. Questionnaires were completed by 50 women during the period from July 20, 2000 to January 12, 2001. The sample was divided into three groups(the normal group of 16 cases and the osteopenia group of 12cases and the osteoporosis group of 22 cases). Bone mineral density(BMD) of lumbar spine was measured using energy absorptiometry. Results: The bone mineral density of the lumbar spine decreased with aging. The bone mineral density of the lumbar spine decreased with the serum Calcium and Phosphorus and Alkaline phosphatase increased. The mean bone mineral density of the lumbar spine of healthy women in age(50~59) was 0.87g/$cm^2$, the lumbar spine of women with low back pain in age(50~59) was 0.77g/$cm^2$. In the multiple regression of risk factors to bone mineral density(BMD) of lumbar spine were correlated with age, marriage existence, exercise time, the loving food of taste, calcium, bone mineral density standard T scores(p<0.05). The experience for LBP increased as weight increased(Odds ratio=999.000). The experience for LBP increased as number of Exercise decreased(Odds ratio=999.000). The experience for LBP increased as menopause existence increased(Odds ratio=999.000). The experience for LBP increased as serum Calcium and Phosphorus increased (Odds ratio=999.000). however all four variables had significant no relationship. The correlation in variables in relation to low back pain and bone mineral density, age showed contra-correlation with low back pain existence, Alkaline phosphatase(p<0.01). Weight showed contra-correlation with body mass index(BMI)(p<0.01). Exercise time showed correlation with number of exercise(p<0.01). The loving food of taste showed contra-correlation with Alkaline phosphatase(p<0.05). Bone mineral density showed correlation with menopause existence(p<0.05). Conclusions: Results from this study indicated that a statistically significant association between bone mineral density of the lumbar spin and age, marriage existence, exercise time, the loving food of taste, calcium, bone mineral density standard T scores. In logistic regression test, there were no related variables. The combination of bone mineral density measurement and assessment of the bone turnover rate by measuring biochemical would be helpful for the treatment of patients with risks of osteoporosis. The more precise study for risk factors to osteoporosis is essential.

  • FMDV is a viral pathogen that caused foot-and-mouth disease in animals. VP1 is a major capsid protein of FMDV. It is known as one of best materials for the FMDV diagnosis and for the development of protein vaccine. In this study, 633 bp of VP1 gene was modified for the expression of VP1 in plant, based on the VP1 DNA sequence from FMDV taiwan O type and from FMDV isolated vietnam. The. deduced DNA fragment was artificially synthesized using the multiple fragment extension with long-nucleotides. A new plant transgenic vector system, pCAMBIA139011 was constructed on the basis of pBI12l and pCAMBIA1390. Using this vector system and GFP gene or modified VP1 gene, each target gene was introduced into Nicotiana tabacum. The insertion of whole target gene was successfully confirmed in each transgenic plant named GFP-A7 and VP1-4, respectively. The expression level of each gene was estimated by RT-PCR and Real-Time PCR using VP1, GFP specific primers.

  • For the myopia eyes of the people which are ametropia, the classified distribution has showed % for the simple myopic, 50% for the compound myopic astigmatism, 15% for the simple myopic astigmatism and 19% for the mixed astigmatism. The myopic ametropia for the both eyes has the distribution of 35% for -0.50D~-2.00Dptr, 54% for -2.00~6.00Dptr, and 11% for over -6.00Dptr. The classifying distribution for the age for the myopic ametropia was 54% for 15~20, 22% for 21~40, 14% for 41~60 and 10% for 61. The occupational distribution for the myopic ametropia has showed 61.5% for the student(Middle, High, College), 13.5% for the office worker, and 15% for the house wives as well as the small business. The hour affecting the refraction most for a day was after P.M. 7 which recorded 45% as the highest value. The reason is that the myopia degree decreases in the morning as the cornea flats and the situation is reversed in the afternoon so that there is a difference of Sph -0.50D and as getting darker the refraction degree of the light coming through the enlarged pupil refraction around the cornea is high. For the seasons the highest myopic degree has been recorded for 68% in the summer due to the shortage of nutrition and the climination inside the body by the exhaustion of sweat. In the blood types A and B are distributed closely as 34% and more active man with O has recorded higher myopic degree than woman. However woman showed higher accommodation power than man regardless the blood types. In the characteristic factors of myopic eye, the character feels fatigue easily has showed the distribution for 42% which is the highest and it could be classified largely by two the.

  • Two Lectins, designated FVL-1 and FVL-2, were isolated and purified from the fruiting bodies of edible mushroom Flammulina veluripes using ammonium sulfate fractionation, ethanol treatment, DEAE-TOYPEARL ion-exchange column chromatography, and TSK-Gel HW-55F column chromatography. Specific activity increased 18 folds for FVL-1 and 7.9 folds for FVL-2 from ethanol treated sample. SDS-PAGE of FVL-1 and FVL-2 gave apparent molecular mass of 10.6 kDa and 37 kDa, respectively. FVL-2 agglutinated all type of human erythrocytes (A, B, AB, and O). However, FVL-1 agglutinated more human erythrocyte type O than type A, B, and AB. The hemagglutination activities of the FVL-1 were effectively inhibited by bovine submaxillary and porcine stomach mucins(BSM and PSM), fetuin, asialofetuin and cations, such as $Cu^{2+}$, $Mg^{2+}$, $Ca^{2+}$, $Mn^{2+}$ and $Fe^{2+}$. However, FVL-2 was not inhibited by any cations. The hemagglutination activities of the two lectins were not inhibited by the sugar, such as lactose, galactose and sugar derivatives. FVL-1 and FVL-2 were stable at pH $5{\sim}11$ and pH $4{\sim}7$, respectively. FVL-1 was stable below $55^{\circ}C$ and FVL-2 was below $45^{\circ}C$.

  • In Korea, all domestic made test systems for detecting antibodies in HIV-1 contain the antigens from human immunodeficiency type 1 (HIV-1) subtype B. However, because HIV-1 subtype O is significantly different in amino acid sequences from all other subtypes of HIV-1, there has been a need for developing a test for detecting antibodies in subtype O. For this purpose, the entire nucleotide sequence corresponding to the extracellular domain of the transmembrane glycoprotein of HIV-1 subtype O was synthesized with consideration of Escherichia coli condon usage. Various regions of the extracellular domain were cloned into E. coli expression vectors and tested for levels of protein production. The nucleotide sequence, named ECTM, that can encode a 129 amino acid-long peptide, was found to be expressed at a high level in E. coli. The protein of approximately 17 kDa specifically reacted with sera from individuals infected with HIV-1 subtype O. The ECTM protein was purified to near homogeneity by the CM-T gel chromatography, using concentrated, denatured inclusion bodies. In Western blot analysis, the purified viral antigen reacted with sera from individuals infected with subtype O more efficiently than subtype B. The enzyme linked immunoabsorbent assay (ELISA) system was developed using the subtype O viral protein and compared with the commercially available kit lacking the antigens from subtype O. The ELISA kit containing the subtype O antigen ECTM alone efficiently reacted with sera from individuals infected with subtype O. The subtype O antigen-containing kit produced a positive absorbence even when sera were diluted 512-fold, suggesting a high sensitivity. The commercially available kit also reacted with subtype O sera, but produced a negative result at a dilution of 8-fold. Our results suggest that the currently available kit may not be able to efficiently detect subtype O sera and that the viral protein developed in this study may be added to the current system to maximize the detection of sera from individuals infected with subtype O.

  • Semi-solvent type cleaning agents were prepared by mixing naphthenes, natural terpene oil, surfactant and water, and measured their physical properties. And also, cleaning efficiency for flux and grease was measured by gravimetric method. By measuring the physical properties, pH for cleaning agents were 6.0~6.7, surface tension, 27.4~28.4 dyne/cm, and wetting index, 8.65~12.46 (with water), 11.99~17.43 (without water). The cleaning agent composed of naphthene, 30 wt%, natural terpene oil, 45 wt%, surfactant, 13 wt%, co-surfactant, 12 wt%, and water, 0 wt% had the largest wetting index, and shown the most effective cleaning properties for flux (98.66%) and grease (93.44%). The conductivity with $0.5{\sim}0.9{\mu}s/cm$ to the cleaning agent containing small amount of water was found to form W/O type microemulsion.
