Purpose: This study was done to evaluate validity and reliability of the Korean version of the expanded nursing stress scale (ENSS). Methods: Forward-backward translation of ENSS from English to Korean was conducted. The translated instrument was pilot-tested and administrated to 285 nurses who worked in five general hospitals in Korea. Internal consistency reliability was assessed using Cronbach's ${\alpha}$ and composite reliability. Validity was evaluated through construct validity with confirmatory factor analysis, convergent and discriminant validity. Results: The Korean version of ENSS showed a reliable internal consistency with Cronbach's ${\alpha}$ .95 and composite reliability .99. Model fit indexes for 46 items were validated by confirmatory factor analysis(goodness of fit index .82, Tucker-Lewis index .92, root mean square error of approximation .04), indicating suitable construct validity. Factor loading of the 48 items (.47~.88) and average variance extracted out of nine factors (.52~.71.) indicated satisfactory convergent validity. Some values of square of the correlation coefficient between factors (.12~.89) were higher than average variance extracted values of each factor (.52~.71) so that it partly satisfied discriminant validity. Conclusion: Findings show that the Korean version ENSS has good reliability and suitable validity; therefore, can be used to assess and identify Korean nurses' job stress.

Volatile flavor compounds of Chamaecyparis obtuse essential oil were extracted by simultaneous steam distillation extraction (SDE) and supercritical fluid extraction (SFE) and analyzed by GC-MS. A total of 48 and 50 components were identified in essential oil by SDE and SFE, respectively. Monoterpenes, oxygenated monoterpenes, sesquiterpenes, oxygenated sesquiterpenes, and diterpenes in essential oil by SDE were 37.24, 10.9, 9.61, 0.22, and 0.22%, respectively. In the case of SFE, they were 19.1, 23.3, 22.66, 1.31, and 10.57%, respectively. Antioxidant activities were increased with the increase of essential oil up to $80{\mu}L/mL$, irrespective of extraction method. Especially, when the essential oil concentration extracted by SDE was increased from 20 to $80{\mu}L/mL$, the antioxidant activity was increased from 10.5 to 55.1%. However, over $80{\mu}L/mL$ of essential oil, an equilibrium state was maintained. In the case of essential oil extracted by SFE, it was decreased compared to that of SDE. For the improvement of atopic dermatitis, various cosmetics such as an ato-cide soap, ato-cide spray, and ato-cide lotion containing essential oil extracted by SFE were tested. About over 90% was useful for the improvement of atopic dermatitis after 4 weeks of clinical trial targeting 40 female adults. These results demonstrate that ato-cide soap, ato-cide spray, and ato-cide lotion containing essential oil extracted by SFE could be used in functional cosmetics.

This study was to evaluate the genotoxic effects of airborne particulate matters using single cell gell elec trophoresis (comet assay) in A549 human lung carcinoma cells. The total suspended particulate (TSP) was collected on back-up filter in Chuncheon, Kangwon Do, South Korea from April, 2003 to February, 2005. The concentrations of TSP, B(a)p and most of heavy metals seemed to be higher in spring and winter, and lower in summer. And they showed higher concentration in the commercial areas and the residential area having more traffics than in the rural area. It was found that A549 cells interacting with the organic extract of TSP showed more DNA single-strand breaks compare to untreated cells. The genotoxicity of the organic extract of TSP was increased with the pre-treatment of S-9 mixture during the culture or with the treatment of endonuclease after cell lysis. The DNA damage by the organic extract of TSP was higher in winter and the commercial area than in summer and the rural area. This study suggests that TSP, heavy metals and B(a)P analyzed showed significant variation depend on the seasons and the areas which are correlated with the DNA damage evaluated by Comet assay, indicating that genotoxic biomarker is useful for toxicological evaluation of air quality.

This study aims to establish basic data for efficient management of rural water by analyzing regional irrigation facilities and benefitted areas in the statistical yearbook of land and water development for agriculture at the watershed level. For 511 domestic rural water use areas, water storage facilities (reservoirs, pumping & drainage stations, intake weirs, infiltration galleries, and tube wells) are spatially distributed, and the benefitted areas provided at the city/county level are divided by water use area to provide agricultural water supply facilities. The characteristics of rural water district areas such as benefitted area, were analyzed by basin. The average area of Korea's 511 rural water districts is 19,638 ha. The average benefitted area by rural water district is 1,270 ha, with the Geum River basin at 2,220 ha and the Yeongsan River basin at 1,868 ha, which is larger than the overall average. The Han River basin at 807 ha, the Nakdong River basin at 1,121 ha, and the Seomjing River basin at 938 ha are smaller than the overall average. The results of this basic analysis are expected to be used to set the direction of various supply and demand management projects that take into account the rational and scientific use and distribution of rural water and the characteristics of water use areas by presenting a quantitative definition of Korea's agricultural water districts.

본 연구에서는 큰뱀무 추출물의 항산화 활성 및 미백과 주름에 관련된 tyroinase, elastase 저해 효과에 관한 조사를 수행하였다. 추출물의 free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) 소거활성($FSC_{50}$)은 ethyl acetate 분획에서 $4.70\;{\mu}g$/mL로 측정되었다. Luminol-의존성 화학발광법을 이용한 $Fe^{3+}-EDTA/H_2O_2$ 계에서 생성된 활성산소종(reactive oxygen species, ROS)에 대한 큰뱀무 추출물의 총 항산화능은 ethyl acetate 분획 $0.22\;{\mu}g$/mL로, ethyl acetate 분획에서 가장 큰 활성을 나타내었다. 큰뱀무 추출물에 대하여 rose-bengal로 증감된 사람 적혈구의 광용혈에 대한 억제 효과를 측정하였다. 큰뱀무 추출물의 경우 $1{\sim}25 \;{\mu}g$/mL의 농도에서 광용혈을 억제하였다. 특히 ethyl acetate 분획은 $10 \;{\mu}g$/mL 농도에서 ${\tau}_{50}$이 416.20 min으로 매우 큰 세포보호 효과를 나타내었다. 미백 효과측정으로는 tyrosinase의 활성 저해 효과($IC_{50}$)를 측정하였는데 ethyl acetate 분획에서 $95.23 \;{\mu}g$/mL로 나타났으며 elastase의 활성 저해 효과($IC_{50}$)는 50 % 에탄올 추출물과 ethyl acetate 분획이 각각 6.27, $4.31\;{\mu}g$/mL로 나타났다. 이상의 결과들은 큰뱀무 추출물이 $^1O_2$ 혹은 다른 ROS를 소광시키거나 소거함으로써, 그리고 ROS에 대항하여 세포막을 보호함으로써 생체계, 특히 태양 자외선에 노출된 피부에서 항산화제로서 작용할 수 있음을 가리킨다. 또한 큰뱀무 추출물의 ethyl acetate 분획의 tyrosinase, elastase 저해활성으로부터 항산화 및 항노화 화장품 소재로서의 응용 가능성을 확인하였다.
