The applicability of the combined nearly ideal binary solvent/Redlich-Kister (CNIBS/R-K) equation for correlation of various solvatochromic parameters (SP) with composition is shown employing 84 experimental data sets for aqueous and organic binary solvent systems at temperatures ranging 15 to $75^{\circ}C$. The model provides a simple computational model to correlate/predict different SP values in various binary solvent systems. In proposed equations, $MPD_s$ (mean percentage deviations) are between 0.0500% and 6.9591% in mixtures of dimethyl sulfoxide with 2-methylpropan-2-ol and benzene with 2-methylpropan-2-ol, respectively. Correlation of the calculated and experimental values of various SP give an equation with an overall mean percentage deviation (OMPD) of 1.1900, $R^2$ = 0.99692, s.e = 0.01223 and F = 341925.51. Approximately 70% of the calculated SP values have IPD (individual percentage deviation) lower than one and it is possible to predict unmeasured SP values by using only eight experimental data.

The SP quality assessments from national IT industry promotion agency of Korea(NIPA) assesses ability of software development process. And the SP quality assessments is getting popular over the nation. But, in the SP quality assessments, there is no concern about security attribute. In this paper new secure process base on ISO 27001 is proposed for the organization that is already passed SP quality assessments. This process can detect security threatening factors and gives chance to protect those factors. Furthermore, since detected security weaknesses can be used as a measurement, the system can be managed in aspect to security attribute.

The crystal structures of two alditol acetates, D-glucitol hexaacetate and xylitol pentaacetate, have been determined by diffraction methods with Mo-K$\alpha$radiation, using direct methods for phase determinations. The crystal data are: for D-glucitol hexaacetate, P2$_1$, with a = 10.275 (2), b = 8.363 (1), c = 12.560 (5) $\AA;\beta$ = 95.97 $(2)^{\circ}$, Z = 2; for xylitol pentaacetate, P2$_1$/C with a = 18.126 (1), b = 11.422 (2), c = 8.649 (1) $\AA$, $\beta = 95.03 (1)^{\circ}$, Z = 4. Both molecules have extended zigzag carbon chain conformations which differ from previous studies of the structures of D-glucitol and xylitol and also differ from NMR studies on alditol acetates. The bond lengths and angles are normal, with mean values over both structures of C($sp^3)-C(sp^3): 1.514 (10),\; C(sp^3)-O: 1.444 (6),\; C(sp^2)-O: 1.347 (9),\; C(sp^2)=O: 1.197 (6),\; C(sp^2)-C(sp^3): 1.479(9){\AA},\; C(sp^3)-C(sp^3)-C(sp^3): 114.6 (17),\; O-C(sp^3)-C(sp^3): 109.4 (23),\; C(sp^2)-O-C(sp^3): 117.4 (6),\; O=C(sp^2)-O: 122.6 (6),\; C(sp^3)-C(sp^2)-O: 111.8 (7),\; C(sp^3)-C(sp^2)=O: 125.5 (4)^{\circ}$. The atoms of acetate groups are in coplanar. There are no particularly short intermolecular contacts and the molecules are held together by van der Waals force only.

Objective: The purpose of this study was to examine the different effects on labor pain, length of delivery time, and hemoglobin for primipara women treated by San-Yin-Jiao(SP-6) acupressure of 15 minutes or 30 minutes. Methods: The design of this study was a randomized clinical trial with two experimental groups and one control group, the participants included primiparas who underwent vaginal delivery. Data were collected using a structured questionnaire consisting of general characteristics with a subjective labor pain scale with VA.S, and length of delivery time and hemoglobin were collected in the medical record. Data was analyzed using descriptive statistics, x2- test, t-test, and ANCOVA. Results: There was statistically significant lower labor pain in the group of 30 minutes SP6 acupressure than the control group(t=7.733, p=.007), and there was statistically significant short length of delivery time in the group of 15 minutes SP6 acupressure than the control group(t=-2.230, p=.030). Conclusions: Even though we could not found a consistent effect with the SP6 acupressure, It was found that there was effect on shortening length of delivery time by 15 minutes of SP6 acupressure or lessening labor pain by 30 minutes of SP6 acupressure without risk of blood loss. It is necessary to replicate the study with a larger number of participants to find a consistent result.

Type-3 cylinder liner has a limitation of machining the standard specimen for fracture toughness test because it has approximately 5 mm in thickness as well as a curvature. Hence, it needs to be employed a miniature specimen test technique to evaluate fracture toughness of the cylinder liner. In this study, small punch (SP) test method was employed to evaluate fracture toughness of the cylinder liner. Load-displacement curve result measured from the SP test showed that the liner material was failed during membrane stretching in the general SP load-displacement curve. Additionally, it was shown that liner material was isotropic although the amount of plastic deformation was different depending on the direction due to manufacturing process characteristics. Fracture toughness, $J_{Ic}$, was evaluated using the SP test data. The value of fracture toughness obtained was $13.0kJ/m^2$. This value was similar to that of the same kind of materials. Therefore, the fracture toughness evaluated using the SP test data was reasonable.

Coagulase-negative Staphylococcus sp #39, isolated from raw-milk showed reduced susceptibility to vancomycin. The minimun inhibitory concentration for strain #39 was at 8$\mu\textrm{g}$ of vancomycin per ml. Transmitting electron microscopy displayed that this strain had a 2.5-3.5 times thicker cell wall than a vancomucin sensitive strain of Staphylococcus sp. The strain #39 also had an increased cell volume. These data indicate that the reduced susceptibility may be due to the thickness of the cell wall of the test strain.

An endophytic fungus, Penicillium sp. JVF17, was isolated from a leaf of Vitex rotundifolia in coastal area of Jeju island. Chemical investigation of this fungal strain resulted in the isolation of four compounds, piceol (1), cyclo (${\text\tiny{L}}-Pro-{\text\tiny{L}}-Val$) (2), isochromophilone VI (3), and dicitrinin A (4). Their chemical structures were elucidated by comparison of their spectral data such as NMR and ESIMS with reported literature values.

Purpose: In the study effects of San-Yin-Jiao (SP6) acupressure on anxiety and pulse during labor, and on neonatal status were examined. Method: The design was a randomized controlled clinical trial with a double-blind method. Data were collected before (pre) and after (post) treatment using structured questionnaire, anxiety scale, pulse rate, umbilical vein pH and Apgar scores. The experimental group received SP6 acupressure for the duration of each uterine contraction over a period of 30 minutes, but the control group received SP6 touch. Results: The anxiety scores between the two groups increased, but the increase was less in the SP6 acupressure group and the difference was statistically significant (p=0.019). Maternal pulse rate was not significantly different immediately after treatment (p=0.711), at 30 and at 60 minutes (p=0.140 ; p=0.108), but while the SP6 acupressure group had a stable pulse, the SP6 touch group showed an increased rate. There was no significant difference between the two groups for umbilical vein pH (p=0.124), and neonatal Apgar score at one and five minutes (p=0.387 ; p=0.979). Conclusion: These findings strengthen the belief that SP-6 acupressure can be used to relieve anxiety during labor with no side effects to either mother or baby.

Objectives : The aim of this study was to evaluate the effect of $SP_6$ moxibustion on the primary dysmenorrhea. Methods : The data was collected from subjects who was suffering for dysmenorrhea. The subjects were employed using Measure of Menstrual Pain(MMP) and Menstrual Symptom Severity List(MSSL) questionnaire. We treated the subjects with $SP_6$ moxibustion and measured Skin Resistance Variability(SRV) before and after treatment. The method of analysing data was paired t-test. Results : 1. $SP_6$ moxibustion produced a significant decrease in symptoms of primary dysmenorrhea. Results : 2. The SRV of 2, 3 area was significanltly changed after $SP_6$ moxibustion. Conclusions : $SP_6$ moxibustion was effective in decreasing the symptoms of primary dysmenorrhea. The SRV results suggest that women with primary dysmenorrhea may have organic energy deficiency and functional abnormality of the hypothalamus-hypophysis-ovarian axis.
