Six strains of Bacteroides fragilis group were isolated from clinical specimens, and these isolates were classified by the resistance to bile and kanamycin, and by catalase and indole reaction. Of 6 strains, 4 strains were belonged to B. fragilis and 2 were B. uniformis. Among 6 strains, only 2 of B. fragilis harbored plasmids. But these plasmid showed no correlation with phenotypic expression. There were some differences in susceptibility to 23 ${\beta}$-lactam antibiotics, also, marked susceptibility differences were found between 2 species, so these results may be contributed to the treatment of infection due to this micro-organism and the identification of these species.

This Study is to investigate relationship between the consciousness of values in the family household abilities of female university students and on identification of the relationship with there to phenomena. Data was collected for 536 students. Through a structured questionnaire data were analyzed by frequency distribution percentage mean ANOVA Duncan's multiple range test t-test and Pearson's correlation coefficients. Major findings are as follows: 1) The consciousness of values in the family of female university students showed a modern tendency in general. 2) Most subjects showed below medium level of household abilities(48.6 point out of a possible 100) proving to be relatively lower. 3) There were significant correlations between the consciousness of values in the family with respect to household abilities of female university students.

Purpose: The purpose of this study was to provide basic data required to improve nursing resources management and nurse organizations. Methods: The data were collected using a questionnaire. Participants were 294 nurses who were working at 8 hospitals with more than 500 beds located in G and C cities, Korea. Data analysis was done using t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficient and stepwise multiple regression analysis with SPSS. Results: There were significant correlations between self-leadership, clinical competence, job satisfaction and job involvement. Factors affecting job involvement were job satisfaction, self-leadership, length of clinical career and length of career in current department. Job satisfaction was the most influential factor with an explanatory power of 41%. Conclusion: Findings show that to strengthen job involvement, identification and management of factors that affect job satisfaction and self-leadership are required and relevant training and strategies should be developed and used.

Aberrant DNA methylation, as an epigenetic marker of cancer, influences tumor development and progression. We downloaded publicly available DNA methylation and gene expression datasets of matched cancer and normal pairs from the Cancer Genome Atlas Data Portal and performed a systematic computational analysis. This study has three aims to screen genes that show hypermethylation and downregulated patterns in colorectal cancers, to identify differentially methylated regions in one of these genes, SFRP1, and to test whether the SFRP genes affect survival or not. Our results show that 31 hypermethylated genes had a negative correlation with gene expression. Among them, SFRP1 had a differentially methylated pattern at each methylation site. We also show that SFRP1 may be a potential biomarker for colorectal cancer survival.

Corrosion of prestressed concrete structures is one of the main challenges that engineers face today. In response to this national need, this paper presents the results of a long-term project that aims at developing a structural health monitoring (SHM) technology for the nondestructive evaluation of prestressed structures. In this paper, the use of permanently installed low profile piezoelectric transducers (PZT) is proposed in order to record the acoustic emissions (AE) along the length of the strand. The results of an accelerated corrosion test are presented and k-means clustering is applied via principal component analysis (PCA) of AE features to provide an accurate diagnosis of the strand health. The proposed approach shows good correlation between acoustic emissions features and strand failure. Moreover, a clustering technique for the identification of false alarms is proposed.

This paper presents a method to segment object ID(identification) marks on poor quality images under uncontrolled lighting conditions of automated inspection process. The method is based on dynamic programming using multiple templates and normalized gray-level correlation (NGC) method. If the lighting condition is not good and hence, we can not control the image quality, target image to be inspected presents poor quality ID marks and it is not easy to identify and recognize the ID characters. Conventional several methods to segment the interesting ID mark regions fail on the bad quality images. In this paper, we propose a multiple template method, which uses combinational relation of multiple templates from model templates to match several characters of the inspection images. To increase the computation speed to segment the ID mark regions, we introduce the dynamic programming based algorithm. Experimental results using images from real factory automation(FA) environment are presented.

The Purposes of this study are for the assessment of anxiety level and for identification for factors relating to the anxiety of the normal Pregnant women who are impendign or entering labor. The State-Trait Anxiety Inventory is used as the measure of anxiety. The results of the study are as follows: 1. The correlation between state-anxiety and trait-anxiety is 0.459 and the linear regression is y(State-anxiety) : 0.251$\chi$(Trait -anxiety)＋29.27. 2. The maternal state-anxiety is not related to the variables of the age, the educational level, the occupation, the prenatal care, parity, show, labor pain and delivery type except for the premature or early rupture of the fetal membranes. 3. The maternal trait-anxiety is not related to the above-mentioned variables.

In recent years, risks associated with mixed used development in urban regeneration projects which have actively been implemented have been on the rise due to uncertainties and complexities of those projects. Thus, risk management is needed to effectively manage those risks that may occur during the process of a project. Many studies have contributed to deal with risk management of those projects. These studies, however, have focused main on identification stage and deriving the main risk factors and have limitations on presenting the relationship among those risk factors. Since many risks are interdependent and have multiple effects, the purpose of this study is to present a way(ISM method) to provide a hierarchical structural framework of risks in Urban Regeneration. The structural of risks can helps decision makers to trace the actual source of these risks.

In-planned duration and cost at project closing are the two of criteria of successful project and successful project management. In Vietnam, regularly, construction projects are delayed and their costs are overrun. This research employed a questionnaire survey to elicit the causes of this situation by interviewing 87 Vietnamese construction experts. After processing data, 21 causes of delay and cost overruns appropriate with building and industrial project in construction stage were inferred and ranked. Spearman's rank correlation tests showed that there're no differences in the viewpoints between parties in project.

Identification of the modal properties of a structural system has received much attention over the years because of its importance in structural model updating, structural health monitoring and structural control. This paper presents experimental modal test results such as natural frequencies and mode shapes of a scale model of floating structure. A modal testing is performed on the structure and modal parameters for the structure are extracted from the measured data. The results are compared to a finite element model and the correlation between the measured and analytical modal parameters is investigated.
