Mitis group streptococci (MGS) were classified based on the nucleotide sequences 16S rRNA gene (16S rDNA) and comprised 13 Streptococcus species. However, 16S rDNA homogeneity among MGS was too high to discriminate between clinical strains at the species level, notably between Streptococcus mitis, Streptococcus oralis, Streptococcus pneumoniae, and Streptococcus pseudopneumoniae. The purpose of this study was to discriminate between 37 strains of MGS isolated from Korean oral cavities using phylogenetic analysis of the DNA-dependant RNA polymerase beta-subunit gene (rpoB). 16S rDNA and rpoB from clinical strains of MGS were sequenced using the dideoxy chain termination method and analyzed using MEGA version 5 software. The resulting phylogenetic data showed that the rpoB sequences could delineate clinical strains of MGS at the species level. Phylogenetic analysis of rpoB is therefore a useful approach for identifying MGS at the species level.

PURPOSES: The purpose of this study is to propose a new methodology for developing statistical collision models and to show the validation results of the methodology. METHODS: A new modeling method of introducing variables into the model one by one in a multiplicative form is suggested. A method for choosing explanatory variables to be introduced into the model is explained. A method for determining functional forms for each explanatory variable is introduced as well as a parameter estimating procedure. A model selection method is also dealt with. Finally, the validation results is provided to demonstrate the efficacy of the final models developed using the method suggested in this study. RESULTS: According to the results of the validation for the total and injury collisions, the predictive powers of the models developed using the method suggested in this study were better than those of generalized linear models for the same data. CONCLUSIONS: Using the methodology suggested in this study, we could develop better statistical collision models having better predictive powers. This was because the methodology enabled us to find the relationships between dependant variable and each explanatory variable individually and to find the functional forms for the relationships which can be more likely non-linear.

To investigate the effect of acupuncture at Zushanli (ST 36) in this study, gastric endocrine cells (G cell) by avidin-biotinylated complex (ABC) technique and histological examinations (HE; periodic acid schiff, PAS; alcian blue stain) of the stomach were perfomed at 1, 3, 6 weeks in normal rats. In other groups, omeprazole were fed for 1, 3, 6 weeks to compare with acupuncture effect. Acupuncture applied to the ST 36 acupoint and the administration of omeprazole increased G cell significantly at 1, 3, 6 weeks in time dependant manner. Furthermore, acupuncture applied to the other acupoint on GB 34 did not produce significant effect. When the common peronial nerve was dissected, acupuncture of ST 36 acupoint produced change of G cell. These data suggest that acupuncture at ST 36 increased G cell in point specific way and that effect was not related with surrounding nerve.

The measurement accuracy of Tunable Diode Laser Absorption Spectroscopy based Tomography (TDLAST) for the temperature and concentration fields are dependant upon the arrangement method of the used laser beams. This paper reports on the optimization of laser beam arrangements using phantom data. It has been verified that the measurement error of the TDLAST decreased with increase of laser beam numbers. Further, it has been confirmed that perpendicular arrangements between the horizontal and the vertical laser beams without additional diagonal laser beams shows the minimum measurement errors.

This study was performed in a 38-year-old Mongolian pine (Pinus sylvestris L. var. mongolica Litvin) plantation in northeast China. Data were collected from 5 sample trees with different canopy position ranging in DBH from 14.6 cm to 23.8 cm. Sawn speciments that included the biggest knot were taken from the stem below the living crown. Number and distribution of knots per whorl below the living crown were studied by relative height below living crown (RHBC). A linear model expressed as function of whorl age (AGE), whorl height ($H_k$) and the stem diameter at which the whorl was located ($D_k$) was developed to predict the knot diameter and angle. The number of annual rings in four periods and the width of respective zone alone stem were used as dependant variables to analyze the knot develop phases. In average, the number of years from branch birth to ceased forming rings was 7.8, the branches remained alive for 4.2 years without forming annual rings, and branches were occluded 14.4 years after their death. These results can provide abundance branch and knot information so as to describe current and past tree growth dynamic of Mongolian pine plantation.

We here demonstrate the evidence of increased anti-tumor and immunostimulating activities of crude extracts (GAL) from Galium. aparine L. In experimental lung metastasis of colon26-M3.1 carcinoma or B16-BL6 melanoma cells, prophylactically intravenous (i.v) administration of GAL significantly inhibited lung metastasis in a dose-dependant manner. In an in vitro cytotoxicity analysis, GAL at the concentration up to $500\;{\mu}g/ml$ did not affect the growth of B16-BL6 melanoma cells. In contrast, GAL showed the enhancement of splenocyte proliferating activity in a dose-dependent manner. Peritoneal macrophages stimulated with GAL produced various cytokines such as $1L-1{\beta},\;TNF-{\alpha},\;IFN-{\gamma}$ and IL-12. These data suggest that GAL has an antitumor activity to inhibit tumor metastasis, and its antitumor effects is associated with activation of nonspecific immnune related cells.

The offshore structures exposed to harsh corrosive such as the marine environment is essential for the quality management technique throughout the life cycle of initial design, construction and operation. Also, it should satisfy the design life and ensure the safety of the substructure with optimization of design process. This study focused on optimization of design condition for corrosion protection of wind turbine structure and computational analyzing was performed to evaluate the performance of corrosion protection with utilizing practical experimental data. We expect this analytical study contribute to improve the corrosion maintenance stability and economical efficiency of designing wind turbine structures. As a result, the design of cathodic protection system using sacrificial anodes required accurate identification of current density in order to meet the long term design life, which can be seen that a change of structure surface's coating breakdown factor is one of the key influencing factors.

Ability of water extract from Prunella vulgaris Labiatae to stimulate immune system and inhibit tumor metastasis in mice was assessed. In experimental lung metastasis, prophylactic intravenous (i.v.) administration of water extract from P. vulgaris significantly inhibited lung metastasis in a dose-dependant manner. Peritoneal macrophages stimulated with P. vulgaris produced various cytokines such as tumor necrosis factor (TNF)-$\alpha$ and interlukin (IL)-12 as well as induced tumoricidal activity. In an assay for natural killer (NK) cell activity, i.v. administration of P. vulgaris significantly augmented NK cytotoxicity. The depletion of NK cells by injection of rabbit anti-asialo GM1 serum abolished the inhibitory effect of P. vulgaris on lung metastasis of colon26-M3.1 cells. These data demonstrate that P. vulgaris activate innate immune system to inhibit the growth of foreign materials including tumor cells in mice.

The purpose of this study is to structure finance management education programme and to provide basic data orienting finance service system by means of analyzing the level of financial problem and its influential variables. The following is the result of this study: First, the level of financial problem perceived by housewife in urban areas is in the following order ; property which is perceived the least. Second, the level of financial problem perceived by housewife in urban areas is dependant on housewife age, husband education level, husband occupation, the degree of property, the degree of debts, tendency of fortune control, tendency of materialism, feeling of appropriate resource. It is especially noting that housewife in forties shows high level of financial of financial problem recognition than housewife in twenties does. This indicates needs for middle for middle-aged home management in which happens house moving to larger size, education of children, marriage of children, preparation for stabilization basis after children’s marriage, and shortage of surplus money. Third, variables which affect all sub-areas are family property sum, tendency of materialism, feeding of appropriate resources. The less family property sum, the stronger tendency of materialism, and the more perceive feeling of appropriate resources, the more perceive they financial problems.
