The prices of domestic green tea products are relatively expensive and price differences within products of the same levels of quality are various. Also, there is no basic criteria on evaluation of green tea quality. To group 43 commercial green tea products into several parts by the principal component and cluster analyses, this work was done by use of 8 chemical constituents which were analyzed by NIR system. The principal component and cluster analyses revealed 8 groups. The first group included 16 products that had lower free amino acid and theanine contents. The second group included 5 products having higher free amino acid and theanine contents, but lower ash contents. The third group included 13 products showing medium values of 8 constituents. The IV group included 4 products having higher contents of moisture, free amino acids, and theanine. The V group included 1 product showing higher moisture but lower catechins contents. The VI group included 2 products that had higher moisture and catechins contents, but lower free amino acid and theanine contents. The VII group had higher moisture and catechins contents. The VIII group had higher ash and vitamin C contents. The free amino acid contents which were the most important in flavor evaluation of green tea quality did highly positively correlate with the contents of total nitrogen $(0.956^{**}),\;theanine\;(0.981^{**}),\;and\;caffeine\;(0.793^{**})$, but negatively with the contents of ash $(-0.884^{**})$. The catechins used as for functional ingredients did correlate with contents of caffeine(+) and vitamin C(-), respectively.

Purpose : This study examines the effects of pre-eccentric exercise and stretch ing to bicepsbrachii to prevent delayed onset muscle soreness and recovery of muscular function depending on the training intensity with 28 normal adults in their twenties. Methods : The subjects were divided into a control group, a group without any previous eccentric exercise, and a stretching group. Pre-eccentric exercise group conducted exercise with the intensity of 25% of maximal voluntary contraction. Pre-eccentric exercise and stretching was applied before to induce delayed onset muscle soreness and after, 24 hour post, 48 hour post, and 72 hour post. Measurements were conducted to examine pain and muscular function changes before, immediately after, and after inducing delayed onset muscle soreness. After inducing delayed onset muscle soreness, measurements were taken at the 24th hour, 48th hour, and 72nd hour. Results : The pre-eccentric exercise group and stretching group showed a significant difference from the control group by isometric contract ion power and mechanical pain threshold as a result of measuring delayed onset muscle soreness. Conclusion : From these results, electrical stimulation using presynaptic inhibition mechanism of transcutaneous electrical stimulation (TES) had positive effects for walking ability on inhibition of muscle tone in lower extremity. The motor level stimulation group experienced a more significant effect than the sensory level stimulation group. Therefore, the transcutaneous electrical stimulation (TES) is considered to be effective on walking ability increasing through inhibition of muscle tone in lower extremity for rehabilitation of post stroke hemiplegic patients.
Objectives : This study aimed at examining the aspects of utilization of the dental services in some regions and analyzing the related factors with a view to helping the old solve the dental problems and overcome the difficulties. Methods : This investigation was intended for 422 old people living in Jeon-ju city and Jang-su county from July 18, 2006 to August 25 by direct interviewing posing questions. The survey data sets were analyzed by chi-square, correlation, multiple regression and logistic regression. Results : 1. The average number of the existing teeth per an old person was 13.6 and the 28.8% of the old who didn't use denture called for dentures. 2. The annual coefficient of utilization in dental services for an old person was 52.3% and the annual average visits to dental clinics were 3.12 days while 38.6% of the old experienced illegal dental treatments. 3. The affecting factors on the dental utilization for treatment were as follows: family income, dental clinics available, the number of existing teeth, the days of dental trouble, the recognition of the prevention of the dental disease, the knowledge for the dental treatment and the oral health judged by himself. 4. The major variables influencing the utilization of dental services were spouse presence, form of family, income, having a regular dental care, denture presence and the experience of inconvenience in living. Conclusions : To conclude, the following suggestions could be made. First, It was necessary that enforcement practice of free dental prosthesis service and application to the national health insurance in old people's prosthetic therapy for government support because the economic factor was barrier to utilization of the dental services. Second, Dental clinic was required to the health center because availability of common dental services was big impact in utilization of the dental services.

Acinetobacter baumannii strains are emerging pathogens of the nosocomial infection with an increasing frequency in recent years. The therapeutic difficulty due to the wide spread of multiple resistant strains was major problem in A. baumannii infection. It seems likely that high frequency of A. baumannii infection will be increasing epidemiological importance in the future. However, the current limited understanding of the epidemiology of A. baumannii infections is caused by lack of a rapid and practical method for the molecular characterization of A. baumannii strains. This study was undertaken to determine molecular types and genetic similarity among A. baumannii strains isolated from four hospitals by RAPD analysis. Eighty-five strains, including 40 from Chunnam University Hospital, 27 from Dankook University Hospital, 15 from Yonsei University Hospital, and 3 from Seonam University Hospital, were classified into three molecular types. Molecular type II was the most common pattern and included 72 strains. All strains from Dankook University Hospital and 40 strains from Chunnam University Hospital belonged to molecular type I or II. A. baumannii strains form Yonsei University Hospital were very distant similarity values. The range of genetic similarity values among 85 strains of A. baumannii was 0.26 to 1.00. Although phenotypes including biotype and antimicrobial resistance pattern of A. baumannii strains were same or very similar to each other, their RAPD patterns were quite different. Typing with phenotypes was found to be less reliable than molecular typing by RAPD analysis. These results suggest that RAPD analysis provides rapid and simple typing method of A. baumannii strains for epidemiological studies. This work is the first epidemiological report of A. baumannii infections in Korea and it is hoped that results of this work may contribute to a better understanding of the clinical importance and epidemiology of A. baumannii strains.
In order to investigate the diversity of bacterial community in the mud flat of Sunchon Bay, Chunnam province, diversity of amplified 16S rDNA was examined. Total DNA was extracted from sediment soils and 16S rDNAs were amplified using PCR primers based on the universally conserved sequences in bacteria. Clonal libraries were constructed and 111 clones were examined by amplified rDNA restriction analysis (ARDRA) using HaeIII. Clones were clustered based on restriction patterns using computer program, GelCompar II. One hundred different RFLP types were detected from 111 clones. The 20 clones were selected and sequenced according to dendrograms derived from ARDRA, to cover most of the bacterial diversity in the clone libraries. None of the clones were identical to any representatives in the Ribosomal Database Project small subunit RNA databases and GenBank. All sequences showed between 77 and 96.8% similarity to the known 16s rRNA sequence from cultured organisms. The 20 clones sequenced fell into seven major lineages of the domain Bacteria: alpha-, delta-, gamma-Proteobacteria, low G+C Gram positive bacteria, high G+C Gram positive bacteria, Sphingobacteria (Cytophaga) and Cyanobacteria (chloroplast). Among the clones, the Proteobacteria were dominant.
This study did question, and got following conclusion to ready necessary basic data to develop school oral health educational programs because grasp 388 man high school students in Jeolla-bukdo Namwon per June, 2008 realization about oral health and oral health education actual conditions. 1. Students of 56.7% recognized own oral health as is not healthy in realization about subjective oral health, and students of 72.2% were interested in oral health, and was recognizing oral fitness by important health problems. 2. Oral health realization by class was significant difference in toothbrushing reason, cause of dental caries, cause of periodontal disease. Students who respond that know adjusted water fluoridation did only for 10.3%, and it was 43.0% of students who responded that students of 57.0% do toothbrushing because of draft cleanliness, and responds that cause of dental caries is food dregs. 3. Responded that 87.1% is right toothbrushing by oral disease preservative, and next time was on-time oral medical examination 79.4%, smoking resection 58.5%, sugar intake limitation 55.4% round. 4. Students, who oral health education by interest degree of oral health is interested in oral health, is oral health educational experience and the need rate, participation intention was high when educate.

The purpose of this study was to investigate the level of social support, loneliness, alcohol use and perceived health status in college students and to explore the relationships between the variables. The convenience sample consisted of 473 students attending a college located at Chonnam province. Data were collected by a structured questionnaire which included the PRO85-partⅡ Social Support Scale, revised UCLA Loneliness Scale, Alcohol frequency, Perceived Health Status Scale from June 10 to 25, 2001. And data were analyzed by SPSS/PC+program including descriptive statistics, t-test, ANOVA, Pearson's Correlation Coefficients. The results are summarized as follows; 1. The mean scores of social support, loneliness and perceived health status were 3.01($SD={\pm}0.31$), 2.08($SD={\pm}0.34$), 1.64($SD={\pm}0.65$) respectively. 2. Students in use of alcohol mostly reported that they had started a drinking in the period of high school(35.7%), motivated with friendship(32.6%) and drank with their friends(56.9%) in drinking frequency of 2-3times per a month(49.6%). 3. The students who have friend of the opposite sex were significantly more likely to have higher than the students having no friend of the opposite sex in scores of social support. 4. The scores of loneliness were significantly lower in female students than male students, in students with friend of the opposite sex than with no friend of the opposite sex. 5. There were significant negative correlations between social support and loneliness(r=-5.25, p<.000), and between loneliness and perceived health status(r=-0.93, p<.05), while there was a significant positive correlation between social support and perceived health status(r=1.01, p<.05). The findings suggested that supportive social support, especially lowering loneliness, would be a powerful nursing intervention in maintaining good health of college students. And, more variables affecting health status in college students will be identified with further research.
We previously demonstrated that root colonization of the rhizobacterium, Pseudomonas chlororaphis O6, induced expression of a galactinol synthase gene (CsGolS1), and resulting galactinol conferred induced systemic resistance (ISR) against fungal and bacterial pathogens in cucumber leaves. To examine the role of galactinol on ISR, drought or high salt stress, we obtained T-DNA insertion Arabidopsis mutants at the AtGolS1 gene, an ortholog of the CsGolS1 gene. The T-DNA insertion mutant compromised resistance induced by the O6 colonization against Erwinia carotovora. Pharmaceutical application of 0.5 - 5 mM galactinol on roots was sufficient to elicit ISR in wild-type Arabidopsis against infection with E. carotovora. The involvement of jasmonic acid (JA) signaling on the ISR was validated to detect increased expression of the indicator gene PDF1.2. The T-DNA insertion mutant also compromised tolerance by increasing galactinol content in the O6-colonized plant against drought or high salt stresses. Taken together, our results indicate that primed expression of the galactinol synthase gene AtGolS1in the O6-colonized plants can play a critical role in the ISR against infection with E. carotovora, and in the tolerance to drought or high salt stresses.
The effect of respiratory inhibition was investigated by treating conidia or mycelium of Cochliobolus miyabeanus with phenylmercuric 8-oxyquinolinate (PMQ) or. phenylmercuric acetate (PMA) in terms of $O_2$ up take ul/mg dry weight of cells. The results obtained are as follows: 1. In inhibition of mycelial growth, PMQ gave somewhat less effective than PMA, hut there was no remarkable difference between them, and the two indicated strong inhibitory effect on mycelial growth at the range from 0.01 to 1.0 ppm. 2. In inhibition of conidial respiration, PMA gave somewhat stronger than PMQ except at 0.1ppm, but there was no notable difference between them, and it seemed that there was no inhibitory effect at 0.01ppm. 3. PMQ was stronger than PMA in inhibition of mycelial respiration as compared with the cibudail respiration, ration, and the difference between them was about $10\%$. 4. According to the above results, the inhibitory effect of spore germimation by PMQ was the same as to PMA or somewhat lower than that of PMA. The inhibitiry effect of PMQ on mycelial growth was lower than that of PMA.
