  • 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.

  • 한국의 정보통신산업진흥원(NIPA)에서 제공하는 SP 품질 인증은 소프트웨어 개발 프로세스의 역량을 평가 및 인증하는 제도이다. SP 품질인증은 국내에서 개발된 인증모델로서 전국적으로 확산되고 있다. 최근 보안성이 문제되고 있으나, SP 품질 인증에서는 별도의 보안 속성에 대한 프로세스를 정의하고 있지 않다. 본 논문에서는 SP 품질 인증을 획득한 기업 및 조직들의 보안성 향상을 위해 ISO 27001을 기반으로 하는 새로운 보안 프로세스를 제시한다. 제안 프로세스를 통해 보안 위협요소들을 검출해낼 수 있고, 이러한 요소들에 대처할 수 있는 기회를 제공한다. 또한 검출된 보안 취약점은 보안 척도로 이용될 수 있으므로 시스템의 보안 측면 관리가 가능하다.

  • Background: The current study is the first quantitative ethnobotanical evaluation of Fateh Pur Thakyala, an unexplored area of Azad Kashmir, Pakistan. The exploration and quantification of ethnobotanical knowledge among people of the study area mainly focused during field survey. The study likely focuses on documenting and preserving the indigenous knowledge and practices related to medicinal plants in the region. A total 70 informants (45 males and 25 females) selected randomly to collect data were interviewed using semi structured questionnaire. The data like demographic characteristics of informants, methods of preparation, life form, modes of application, parts used, and ethnomedicinal uses was documented. The quantitative indices including relative frequency of citation (RFC), use value (UV), informant consensus factor (ICF), fidelity level (FL), consensus value for plant part (CPP), rank order priority (ROP), percentage respondent knowledge (PRK), were applied to analyze the collected data. Furthermore, primary data were also compared with fifteen papers published from adjoining areas by Jaccard index (JI). Results: The current study reported 135 medicinally important plants species belonging to 115 genera and 54 families. The dominating family was Asteraceae (14 sp.), followed by Fabaceae (11 sp.), Rosaceae (11 sp.), Lamiaceae (8 sp.), Moraceae (5 sp.), Solanaceae, Cyperaceae, Euphorbiaceae (4 sp.) and Poaceae, Sapindaceae, Rhamnaceae, Mrytaceae, Malvaceae (3 sp.) for each. The study revealed that there were small differences in usage of medicinal plants of different families. The herbaceous life form was dominating the study area with (79 sp.) used as herbal medicines followed by shrubs (23 sp.) and trees (33 sp.). The comparative study of for novelty of species and their uses by JI revealed 13 novel plants species which were not reported earlier from this region. Conclusions: Local inhabitants still prioritize herbal medicines as an effective way to treat a wide variety of ailments. Elders and health practitioners of the study area are well aware of indigenous knowledge about medicinal plants, but young people are not much interested in herbal practices. Thus, valuable knowledge about the use of plants is on the verge of decline. The overexploitation and seasonal fires are major threats for medicinal flora in the area.

  • D-glucitol hexaacetate 와 xylitol pentaacetate의 결정구조를 단결정 X-선 회절법으로 연구하였다. D-glucitol hexaacetate 는 공간군 P2$_1$, 단위세포 상수는 a = 10.275 (2), b = 8.363 (1), c = 12.560 (5) $\AA$, $\beta$= 95.97 $(2)^{\circ}$; Z = 2이고, xylitol pentaacetate는 공간군이 P2$_1$/C이고, a = 18.126 (1), b = 11.422 (2), c = 8.649 (1) $\AA$, $\beta$ = 95.03 $(1)^{\circ}$이며 Z = 4이다. 회절세기는 diffractomerer로 얻었고, 분자구조는 직접법으로 밝혔으며, 최소자승법으로 정밀화하였다. 두 분자에 결쳐 결합의 평균길이는 C($sp^3)-C(sp^3$)가 1.514 (10), C($sp^3)-O: 1.444 (6),\; C(sp^2)-O: 1.347 (9),\; C(sp^2)=O: 1.197 (6),\; C(sp^2)-C(sp^3): 1.479(9){\AA}$이고, 평균 결합각도는 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}$이다. 두 분자내의 탄소 사슬들은 extended zigzag chain으로 되어 있어 D-glucitol과 xylitol 분자들의 conformation과는 다르다. Acetate group들의 각 원자들은 모두 한 평편상에 놓여있다.

  • 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 용기 라이너는 두께가 5 mm일뿐 아니라 곡률을 가지고 있기 때문에 파괴인성시험을 위한 표준형 시편의 제작에 어려움이 있다. 따라서 용기 라이너의 파괴인성을 평가하기 위해서는 소형시편 시험기법이 도입되어야 한다. 본 연구에서는 용기 라이너의 파괴인성을 평가하기 위해 소형펀치(small punch, SP)시험법을 도입하였다. SP시험으로부터 측정된 하중-변위 곡선 결과에서 라이너 재료는 연성이 소진하여 막신장 영역에서 파손되었다. 라이너 재료는 제작공정 특성에 기인하여 소성변형량이 방향에 따라 다름에도 불구하고 등방성 파괴양상을 보였다. SP시험 데이터를 사용하여 파괴인성을 평가한 결과 $J_{Ic}=13.0kJ/m^2$ 이었다. 이 값은 동종재료의 파괴인성 값과 유사하다. 따라서 SP시험 데이터를 사용하여 평가한 파괴인성은 타당하며, 완성된 용기 라이너는 유효한 파괴인성 값을 유지하는 것으로 확인 되었다.

  • 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.
