Vibrio vulnificus is a halophilic bacterium frequently involved in human infection of seafood-associated primary septicemia and primary wound infection, mostly in men with over 40-years of age with underlying liver disease. The primary septicemia, which is the most common form of V. vulnificus infection in Korea, is defined as a systemic illness presenting fever or hypotension with recovery of V. vulnificus from blood or tissue without the apparent primary focus of infection. V. vulnificus typically do not produce acid from sucrose, but a case of primary septisemia was found in a patient at Chonnam K hospital in 1993 from whose blood a sucrose-fermenting strain was isolated. The patient was a 62-year-old man, heavy drinker, with underlying liver disease. He consumed a raw seafood dish two days before onset of the present illness. His symptoms were tenderness and swelling on the right foot. He rapidly developed septicemia, resulting in sudden death. V. vulnificus was isolated from the venous blood culture of the patient. On subculture, the isolate formed yellow colonies on TCBS and produced acid from sucrose. Because of these characteristics, species identification was not achieved by the API 20E and was delayed. Other characteristics of the isolate were identical to those of typical V. vulnificus. The isolate was common serotype O4A and possession of V. vulnificus-specific cytolysin gene was detected by PCR. The isolate was susceptible to all the antimicrobial agents tested including tetracycline, but was intermediate to colistin. In conclusion, it is important that microbiologists be aware of the presence of sucrose-positive V. vulnificus when he or she identifies gram-negative bacilli, which is isolated from the blood of patients with a recent history of raw seafood dish consumption.

The present study analyed jitter and shimmer of the deaf in 4 different voicing conditions. Thirty-two male subjects and 27 female subjects participated in the study on a voluntary basis. The age ranged from 6 to 18 for male and 8 to 21 for female subjects. The subjects were either congenitally or prelingually deaf The four different voicing conditions included /a/ prolongation, counting, reading, and conversation. The experiment utilized CSL Visi-Pitch Model 6095(Kay Elemetrics Corp.) to sample and analyze the data. Both jitter and shimmer means were higher than the threshold values(normative data) reported. In addition, this investigation performed two separate 2-factor ANOVAs in order to determine if jitter and shimmer change as a function of gender and voicing condition. The results showed the following. First of all there was the gender effect on shimmer but not on jitter, in that male subjects 'shimmer was higher than females'. secondly, there was the voicing condition effect both on jitter and shimmer. /a/ prolongation and reading produced lower jitter than counting and conversation. /a/ prolongation produced lower shimmer than the remaining conditions. Finally, no interaction between gender and voicing condition existed.

At this point, the universities preparing the 21st century, require a great reform in various ways, especially a renovation of the function of the university library that can provide intellectual and information ability in information society is raised as an imminent task. Information technology, particularly the advanced technology in networking, have already constructed networks for university libraries using the information super-highway and it has enabled formation seekers to get the retrieved results transferred to their personal computers in a second. On the other hand, university libraries playing the most important role as an information center are still not corresponding effectively with the information age since it is tied down to the previous system, policy and tradition. The duty of university library is to distribute the accumulated, processed and stored academic information promptly and accurately to professors, researchers and students who are in need, and thereby to enhance their research capability, However, the present university libraries do not seem to be functioning smoothly due to the lack of an effective administrating system, budget, facilities, and human resources, Accordingly, our university libraries are in urgent need to be of a new and futuristic form appropriate for the 21st century. They must be able to cope with the growth of users' expectation in the future. This study examined several university libraries in the America, the structures of which have been reorganized, and also looked into the network(NACSIS) for the college and research libraries in Japan. In particular, the study focused on the following aspects : 1) changing role of university library, 2) new criteria for evaluating university libraries, 3) urgent need of a network for college and research libraries, 4) administrative support for the university libraries, and 5) case studies of the university libraries in the foreign countries. Finally, this study suggests a model for our university library in the 21st century.

The present study was conducted to measure health-related utility for post-menopausal symptoms among Korean woman. A survey questionnaire was developed to measure utility based on visual analogue scale(VAS) and time trade-off method (TTO). From January 29 to February 3, 2007, a face-to-face interview was conducted with 274 women aged 45 to 60 to ask about their subjective utility for hypothetical health status of mild or severe post-menopausal symptoms. Among the participants, 160 were recruited from outpatient departments of 3 hospitals and 114 from 2 sports centers located in Seoul. For mild symptom, the average utility score of the respondents was $0.63{\pm}0.14$ based on VAS and $0.61{\pm}0.26$ based on ITO. For severe symptoms, the average utility was $0.39{\pm}0.16$(VAS) and $0.44{\pm}0.27$ (TTO). For severe symptom, a higher utility score was observed for TTO than for VAS, which is consistent with earlier studies and thus supports the validity of the utility measurement in this study. Overall, the severity of post-menopausal symptoms of the respondents themselves was not significantly associated with the utility score that the respondents answered for hypothetical health status. Multiple regression analysis results showed that the utility score was significantly higher among respondents with older age, higher education, higher family income, and from hospitals. It is expected that the utility score measured in this study will enhance the understanding of the quality of life of women after menopause and will be used to conduct cost-utility analysis of health care interventions to treat post-menopausal symptoms.

Safety and quality assessment systems are very important in manufacture, storage, transportation, and handling of hazardous materials(hazmat) to prevent hazmat disasters. At present, hazardous materials exist everywhere in our daily lives with various forms of plastics, household products of cleaning and washing detergents, fertilizers or petroleum-related products. However, hazardous materials are dangerous substances when they are released to human or environment. Hazardous materials become very widely used substances in the age of oil-based industrial economy. The Korean Ministry of Environment (KMOE) describes about one hundred thousand types of chemicals are produced and used worldwide. Over four hundred new chemicals are introduced in every year. A crucial question for the Korean hazardous material management may have been raised: Will you be safe from hazardous material incidents? The gas leak disaster at Union Carbide's Bhopal, India in 1984 that made over 6,400 people killed and 30,000 to 40,000 people seriously injured is the representative case for the safety of hazmat. Korea becomes vulnerable to hazmat disaster due to the development of high-tech industry. Thus, the risk assessment system is required to Korea for transferring abandoned hazmat management systems to self-correcting safety systems. This research analyzed characteristics of various hazmat incidents applying statistical analysis methods including frequency analysis or analysis of category data to hazmat incidents for ten years. All of three analyses of category data indicate the significance of causality between hazmat incident site groups and seasons, regional groups, and incident casualty groups.

The purpose of the present study was to investigate the differences of nonlinear characteristics of electroencephalogram (EEG) depending on different sensitivities of behavioral activation system (BAS) and behavioral inhibition system (BIS) of young and elderly groups. The EEGs from Fpl and Fp2 electrodes were recorded during resting condition. The young and elderly groups consisted of 19 and 31 healthy right-handed volunteers, respectively. We estimated 1/f scaling exponent which reflects the nonlinear dynamical complexity of EEG. As results, we found the differences of 1/f scaling exponent between young ant elderly BAS sensitive groups. The 1/f scaling exponent of young BAS sensitive group showed significantly higher values than those of elderly BAS sensitive group at the left prefrontal area (Fpl). The young BAS sensitive group had also a tendency to higher 1/f scaling exponent at the right prefrontal area (Fp2). Decrease of the 1/f scaling exponent indicates the increase of complexity and the decrease of the amount of information related to the statistical distribution. Therefore, the elderly BAS sensitive group has higher complexity than young BAS sensitive group, though they were all classified as BAS sensitive group by BAS/BIS scale. Our results suggest the possibility of correlation between BAS sensitivity an4 age.

Drug-eluting stents (DES) have significantly reduced in-stent restenosis, compared to bare-metal stents (BMS). However, there remains concern for the increased risk of stent thrombosis (ST) associated with DES. The present study sought to evaluate the incidence, clinical characteristics and outcome of ST in patients with acute myocardial infarction (MI) during a 1-year follow-up. 80 patients who developed ST were divided into 2 groups according to stent type: group I (DES-ST, n = 57 ) and group II (BMS-ST, n = 23 ). There were no differences between group I and II in the overall incidence of ST (2.7% vs. 4.3%, p=0.064) and in the incidence of each type of ST: acute ST (8.8% vs. 2.3%), subacute ST (50.9% vs. 60.9%), late ST (19.3% vs. 8.7%), and very late ST (21.1% vs. 17.4%) (p=0.605). Predictors of 1-year mortality were the occurrence of ST (OR 8.12, 95% CI 2.83-23.61, p<0.001), left ventricular ejection fraction<40% (OR 6.41, 95% CI 2.42-16.96, p<0.001), and age${\geq}$75 years (OR 4.98, 95% CI 1.95-12.74, p=0.001).

Among many factors that affect the development of the talent of gifted children, the family factor that first finds and cultivates the talent of gifted children is quite important. The researches on the family of gifted children are mostly concentrated on physical environment out of the home environment, neglecting psychological environment. Although the recreational activity of family with gifted children considerably contributes to the emotional, intellectual and social development of gifted children themselves and to the improvement of life quality of the family members, the recreation of family with gifted children has not yet been studied. Thus, the objective of this research is to present basic materials for seeking the direction to educate parents and to support family with gifted children in order to encourage synergy effect in emotional and social growth of family with gifted children by surveying the property of recreation of family with gifted children. The result of result is as follows. First, the type of family with gifted children tends to be remarkably biased to 'family-oriented activity' and 'elf-development activity.' Second, verifying the significant level of motive for recreational activity of family with gifted children at the variables such as number of family members, parents' age, parents' education level, parents' occupation, etc, it was concluded that they were not statistically significant. The result of this research suggests that education and support for efficient recreation of family with gifted children is necessary to achieve healthy talent of gifted children.

This study aims to historically and academically shed new light on Jamu(字舞) to which there is little reference now on the basis of reference of neighboring country (China), to discover traditional unique contents by considering constituting principles, and to use these data to inherit and develop Jamu as a stage performance which is suited for the present age. The result of this study shows as follows. The first, Seongsumu was made up of the dances making 16 letters-"Seongchocheongo(聖超千古), Dotaebaekwang(道泰百王), Hwangjemannyoun(皇帝萬年), Bojomichang" - by 140 dancers. Made letters were intended to face audiences and this is similar to group gymnastics of today in the aspect and form stakes. The second, it is thought that Youngseongsomu the dance making Cheonhataepyeong(天下太平) and recorded in "Youngseongsomubo" of China is related to 'Wangmodaegamu(王母隊歌舞)' the dance making Cheonhataepyeong(天下太平) during the Moonjing rule and recorded a little in The History of Goryeo, 25 volumes (高麗史 卷25). With this study as a momentum, continuous study is needed on Korean traditional dance inherited barely today in order to develop new various contents of Korean traditional arts which are being forgotten by studying and researching related references in neighboring countries such as China and Japan.

The present study was conducted to assess relative importance of hospital attributes considered by patients with spinal diseases in choosing specialty or general hospitals. A total of 230 patients hospitalized with spinal diseases in sampled study sites, including 2 specialty and 2 general hospitals, participated in a self-administered questionnaire survey from April 26 through May 8 2007. Patients were asked to rate the degree of agreement on each of the 15 attributes on a 5-point Likert-type scale (1 : strongly disagree, 5 : strongly agree) for which they chose the hospital because of that specific attribute. Based on a Factor analysis, the attributes were grouped into 4 : facility and environment, accessibility, interpersonal factor, and credibility. Both patient groups from specialty (mean scale score ; 3.75) and general hospitals (3.62) commonly considered 'credibility' to be the most important attribute, followed by 'facility and environment (3.05 and 3.21).' Logistic regression analysis showed that men(Odds ratio(OR)=0.333) and those with monthly income of $\geq$ 4 million won (OR=0.298) were less likely to choose specialty hospitals. Age groups of 30 to 39 years old (OR=5.140) and $\geq$ 60 years old(OR=4.761), and professionals (OR=5.207) tended to choose specialty hospitals. Patients expressing more importance on 'facility and environment' attribute were less likely to use specialty hospitals (OR=0.571), whereas those emphasizing 'accessibility' were more likely to use specialty hospitals(OR=1.487). The findings of significant difference in patient's demographic characteristics and consideration in hospital attributes would contribute to have a better understanding on patient's choice behaviour and to develop strategy to improve patient's satisfaction.
