The aim of this study was to evaluate 30 phenolic compounds in adzuki bean germplasm. Adzuki 21653 had the highest content of total phenolics compounds ($6597\;{\mu}g\;g^{-1}$) while 104372 had the lowest concentration. The average total phenolic content of Japanese ($2432\;{\mu}g\;g^{-1}$) adzuki beans was higher than that of Korean ($2256\;{\mu}g\;g^{-1}$) adzuki beans. The average total phenolic contents were $2507\;{\mu}g\;g^{-1}$ in small sized adzuki beans from Japan and $2459\;{\mu}g\;g^{-1}$ in those from Korea. In large sized adzuki beans, the average total phenolic contents were $1315\;{\mu}g\;g^{-1}$ in Japanese seeds and $1232\;{\mu}g\;g^{-1}$ in Korean seeds. The average total phenolic contents in medium seeds were $2369\;{\mu}g\;g^{-1}$ in Japanese adzuki beans and $1397\;{\mu}g\;g^{-1}$ in Korean ones. In small seeds, the total phenolic contents of adzuki beans varied from $524\;{\mu}g\;g^{-1}$ to $6597\;{\mu}g\;g^{-1}$ in Japanese ones and from $375\;{\mu}g\;g^{-1}$ to $6569\;{\mu}g\;g^{-1}$ in Korean ones. Japanese and Korean adzuki beans were divided into landraces and wild adzuki beans. In this study, the wild adzuki beans showed higher contents of total phenolics than the native varieties. Specifically, the wild adzuki beans from Korea had the highest concentration of phenolics ($3403\;{\mu}g\;g^{-1}$). All adzuki bean germplasms were measured for their color and were classified into four groups accordingly: A; L < 30, +a, +b; B; L < 30, +a, -b, C; L > 50, +a, +b, D; L > 50, +a, -b. Especially, group B had the highest concentration of total phenolic compounds ($2827\;{\mu}g\;g^{-1}$), whereas group C had the lowest concentration ($1882\;{\mu}g\;g^{-1}$).

Hugo $H\"{a}ring$(1882-1952) belonged to that special generation of architects born in the 1880s which became responsible for the establishment of Modern Movement in the 1920s as W. Gropius, Mies van der Rohe and Le Corbusier, etc. Although he have been overlooked by many historian, He was a key figure of the Modern architecture and as the main theorist for Organic stream in German architecture. He is well-known for his theory of 'Neues Bauen(New Building)', the organic functionalism that is epitomized as the design process from the inside outwards, starting with the life-processes of dwelling. So he argued that the builder must become aware of the life process his building is to serve, and he should not impose a form but try to find the form. These concepts are expressed well in his key-words, the 'Organwerk(organ-work)' and 'Leistungsform(form as achievement)'s. $H\"{a}ring's$ theory can be found in the short early essay, 'Wege zur Form(approaches to form)' of 1925. But His concept of 'function' is based on the speciality and individual identity that concerned him from the start, not purely pragmatic aspects. After 1940s his theory moved increasingly in this direction. He defined this as the transition from 'Organwerk' to 'Gesetaltwerk', from mere anatomy to essence, being, personality, life. It suggest that Hugo Haring's idea of Gestalt is a dimension of mystical or symbolic meaning. This paper Is about the way in which this theoretical transition can be parallel with contemporary philosophers as E. Cassirer's philosophy of symbolic forms and M. Heldegger's phenomenology. And the key example of this viewpoint is (1921-1926) near Lubuk in Germany, with its 'cowshed' of pear shaped plan devised around the requirements and rituals of farm. This study presents the symbolic conception of Hugo $H\"{a}ring's$ theory can propose the ability of a symbolic intuition as a view that re-integrate technical thinking with knowledge of other kinds beyond the immediate material.

In order to search for specific genotypes related to this unique phenotype, we used whole genomic DNA microarray to characterize the genomic diversity of Helicobacter pylori (H. pylori) strains isolated from clinical patients in China. The open reading frame (ORF) fragments on our microarray were generated by PCR using gene-specific primers. Genomic DNA of H. pylori 26695 and J99 were used as templates. Thirty-four H. pylori isolates were obtained from patients in Shanghai. Results were judged based on In(x) transformed and normalized Cy3/Cy5 ratios. Our microarray included 1882 DNA fragments corresponding to 1636 ORFs of both sequenced H. pylori strains. Cluster analysis, revealed two diverse regions in the H. pylori genome that were not present in other isolates. Among the 1636 genes, 1091 (66.7%) were common to all H. pylori strains, representing the functional core of the genome. Most of the genes found in the H. pylori functional core were responsible for metabolism, cellular processes, transcription and biosynthesis of amino acids, functions that are essential to H. pylori's growth and colonization in its host. In contrast, 522 (31.9%) genes were strain-specific genes that were missing from at least one strain of H. pylori. Strain-specific genes primarily included restriction modification system components, transposase genes, hypothetical proteins and outer membrane proteins. These strain-specific genes may aid the bacteria under specific circumstances during their long-term infection in genetically diverse hosts. Our results suggest 34 H. pylori clinical strains have extensive genomic diversity. Core genes and strain-specific genes both play essential roles in H. pylori propagation and pathogenesis. Our microarray experiment may help select relatively significant genes for further research on the pathogenicity of H. pylori and development of a vaccine for H. pylori.

Since Robert Koch found tubercle bacilli in 1882, the studies on tubercle bacilli of human and animal had been carried out. Being old tuberculin(OT) introduced in 1890, the specificity of the diagnosis of tuberculosis has been improved by continual uses of heat concentrated synthetic medium(HCSM) and purified protein derivatives(PPD) tuberculin. Now, two types of tuberculin test are used worldwidly ; the single intradermal test(SIT) using bovine tuberculin and the single intradermal comparative tuberculin test(SICTT) using avian and bovine tuberculins. In the SICTT, each countries have used with different combination of both avian and bovine tuberculins' titers. However, this kinds of studies have not reported in Korea. Therefore, the studies on the combination of their tuberculins' titers were performed through intradermal test of guinea pigs sensitized with either Mycobacterium bovis or M avium and were examined in 10 cattles of SIT positive reactors. Also, IFN-${\gamma}$ assay, the latest diagnostic method of bovine tuberculosis, was experimentally applied to SIT positive reactors. For determining the optimal titers, sensitized guinea pigs with M bovis and M avium were intradermally injected avian and bovine tuberculin. In guinea pigs sensitized with M bovis, bovine tuberculin 50 T.U. showed significant difference from all tested concentrations of avian tuberculin(p < 0.05). In guinea pigs sensitized with M avium, there is significantly different between bovine tuberculin and avian tuberculin by 25 T.U.(p < 0.01). Therefore, optimal titers of bovine and avian PPD tuberculins' titers for the SICTT in Korea were 5,000 and 2,500 tuberculin units, respectively, and the swelling diffences between bovine and avian site in SIT positive reactors were above 3mm. Also, in IFN-${\gamma}$ assay, the 9 SIT positive reactors were showed all the positive reactions.

Statements of problem: Zirconia core is used for posterior fixed partial dentures because it's good mechanical properties. Stress is concentrated on connectors in fixed partial dentures, so the proper design of connector areas is needed for adequate mechanical long-term properties of any prosthesis. The area of connector is critical, but tooth size and surrounding soft tissue limit the connector design. Purpose: The purpose of this study is to compare fracture strengths between different connector designs of zirconia core for posterior fixed partial dentures manufactured with CAD/CAM system and determining the optimal connector design satisfying strength and hygiene. Material and method: The following four groups of 40 posterior fixed partial denture specimens(each group 10) were fabricated as followed; group 1 vertical height of connector is 3mm (control group, all groups have the same condition); group 2, lingual vertical 1mm reinforcement on connector; group 3, lingual vertical 2mm reinforcing on connector and group 4, lingual vertical 3mm reinforcing on connector. Specimens were subjected to compressive loading on the central fossa of pontic by instron. SEM was used to identify the initial crack and characterize the fracture mode. Results: The results were as follows: 1. The mean fracture load of the non-lingual reinforcing group was 1212N and the lingual vertical 1mm reinforcing group was 1510N, the lingual vertical 2mm reinforcing group was 1882N, the lingual vertical 3mm reinforcing group was 1980N. 2. The reinforcing groups were statistically significant compared to non-reinforcing groups(P<0.001). 3. There were 2, 3mm reinforcing groups that were statistically significant compared to 1mm reinforcing groups(P<0.001), and the 3mm reinforcing group was not statistically significant compared to 2mm reinforcing groups(P>0.05) 4. Fractures were initiated in gingival embrasures of connectors and processed to the loading site. Conclusion: In this study, lingual reinforcement of connector for improved strength of zirconia based fixed partial denture is nessasary. And long-term study for clinical application is required

Purpose: Active prevention is an essential component in reducing the development of pressure sores. For the high-risk patient group, following the certified pressure sore screening scale as well as educating the patient and the nurses who care for them can lead to optimal management of these patients. Applying a risk assessment scale along with a prevention strategy can reduce medical costs and length of stays at the hospital. The purpose of this study is to evaluate the efficacy of a new pressure sore risk assessment scale based on the universally recommended Braden scale and our prevention program. Methods: From June to August, 2003, our pressure ulcer risk assessment scale was applied to a total of 1882 patients admitted to the experimental group (intensive care unit, neurosurgery, general surgery, and oncology units). It was based on Braden scale. We analysed sensitivity, specificity, positive and negative predictive value and ROC curve to evaluate its efficacy. Pressure ulcer prevention program was composed of patient's education using protocol and specific nursing care. The incidence of pressure ulcers was also measured during the 3 months period, and those were compared to the control group of 1789 patients from March to May, 2002. Results: 118(6.27%) of the experimental group were high-risk with an incidence of pressure ulcers measuring 4 (0.21%). Sensitivity, specificity, positive and negative predictive value of our scale were 100%, 94%, 4%, 100%, respectively, and AUC(area under the curve) was 0.992. In the control group, the incidence of pressure ulcers was 11(0.61%). Statistical analyses using chisquared tests with a significance level of 5%, the results were such that ${\chi }^2=3.6482$(p=0.0561). The results proved to be statistically significant in borderline. Conclusion: The results from this study proved that pressure sore risk assessment scale based on Braden scale has an excellent efficacy, and shows that our pressure ulcer prevention program is partially effective in reducing pressure ulcer incidence.

Essential fatty acids are important essential nutrients during pregnancy. The objective of this study was to compare fatty acid composition of serum phospholipids and essential fatty acid intakes between Korean pregnant women with a single baby and Korean pregnant women with twins. A total of 116 pregnant women who had maintained their health without any symptoms of pregnancy complications participated in the study. The subjects consisted of 57 women of singleton pregnancy and 58 women of twin pregnancy at the 1st, 2nd, or 3rd trimester of pregnancy. A 24-hour dietary recall was administered to each subject to obtain dietary information. The mean ages of the singleton pregnancy group and the twin pregnancy group were 31.44 years and 32.27 years, respectively, and the mean height values were 161.86 cm and 160.64 cm, respectively. The mean daily energy intakes in the singleton pregnancy group were 1639.95 kcal, 1904.71 kcal, and 1882.82 kcal for the 1st, 2nd, and 3rd trimester group, respectively. The mean daily energy intakes in the twin pregnancy group were 1745.99 kcal, 2203.46 kcal, and 2092.26 kcal for the 1st, 2nd, and 3rd trimester group, respectively. There were no significant differences in the mean fatty acid intakes by the type of pregnancy (i.e., singleton vs. twins) and the stage of pregnancy (i.e., 1st vs. 2nd vs. 3rd trimester). However, the mean total fatty acid intake of those at the 1st trimester among the singleton pregnancy group tended to be higher than that of those at the 1st trimester among the twin pregnancy group. Such a trend seemed to be retro-versed. That is, the mean total fatty acid intakes of the twin pregnancy group were higher compared to the singleton pregnancy group for the 2nd and 3rd trimester group. The LA and total n6 concentrations of serum phospholipids of the singleton pregnancy group were significantly higher as the gestational age increased(p<0.05). The $\alpha-LNA$(p<0.05), EPA(p<0.05), and total n3(p<0.001) concentrations of serum phospholipids of the twin pregnancy group were significantly lower as the gestational age increased. The $\alpha-LNA$ concentrations of serum phospholipids in the singleton pregnancy group at the 3rd trimester were significantly higher than that in the twin pregnancy group at the same trimester(p<0.05). The serum phospholipids levels of AA and DHA of the twin pregnancy group were generally higher compared to those of the singleton pregnancy group. Particularly the differences reached at the level of statistical significance for those at the 1st trimester(p<0.01). It is concluded that the study findings imply that fatty acid metabolism may meaningfully differ by the type and stage of pregnancy. Future research needs to be conducted to more elucidate grounding etiology and possible roles of dietary fatty acid intake levels in relation to the study findings.
