  • Purpose: Purpose: This study was undertaken to develop directions for research on nursing practice education and also for standardization of contents of Fundamental Nursing Practice (FNP) by identifying and analyzing the present content and inconsistency in FNP textbooks. Method: Eleven FNP textbooks published between 2007 and 2013 were selected and itemized nursing contents were compared and analyzed. Nursing professors and practicingnurses prioritized contents identified from an actual condition survey based on theoretical reason and clinical guides for each item. Results: Inconsistencies were found for 34 domains with 219 sub items and of them, 21 domains and 84 items needed to be standardized. Number of items that showed consistency between professors and nurses ($ICC{\geq}.800$) was 29 (34.5%) and for complete consistency (ICC=1), 4 (4.8%). Number of items that showed inconsistency between the groups (ICC<.600) was 30 (35.7%) and very low consistency (ICC=0), 10 (11.9%). Conclusion: The results indicate a difference between understood validity of content by professors and by nurses and technical differences among FNP textbooks. Therefore confirmation of the items needing to be standardized and differences in understanding content by professors and by nurses shows a need for standardization of practice education between course and clinical practice. These results provide basic data for developing standardized form of FNP education.

  • HPLC를 이용하여 fructose oligomer인 fructo올리고당(GF2-GF7) 및 inulo올리고당(F2-F4)의 분리, 정량을 실시하였다. TSK-gel amide 80 column과 acetonitrile-water(65:35; v/v) 용매를 사용하여 각 표준당들을 효과적으로 분리할 수 있었으며 이들의 retention time은 분석시마다 거의 변하지않아 재현성이 있었다. 각 당의 농도에 따른 peak면적을 이용하여 표준곡선을 작성한 결과 넓은 당량의 범위에 걸쳐 결정계수가 0.9884이상의 값을 보여 본 HPLC방법에 의한 정량법이 타당한 것으로 나타났다. 또한 기울기는 비슷하나 y축 절편 값이 당마다 크게 상이하여 몇가지 표준당들을 기준으로 하여 모든 당을 일률적으로 정량하는 것은 적합하지 않으며 각 당에 대한 표준곡선을 하나씩 작성하여 정량하여야함을 알 수 있었다.

  • For the purpose of standardization and practicability of nautral dyeing, the mordanting and dyeing properties of Rhusjara ica was studied. Appropriate extraction, dyeing and mordanting condition of Rhusjara ica were determined, and the effect of mordanting method on dye uptake and color fastness of dyed fabric was investigated. The most absorbance of Rhusjara ica solution was 299 nm. The color of Rhusjara ica solution was affected by pH 8~9. The optimum temperature to extract Rhusjara ica was 6$0^{\circ}C$ and dyeing solution for 1 hour. Effective dyeing time to silk was 60min. Effective mordanting temperature was 80~10$0^{\circ}C$, and its time was 30 min. K/S value of dyeing fabrics was recoginazed by mordanting treatment, specially Fe, Al, Cu. K/S value of pre-mordanting was higher than post-mordanting. In the case of Rhusjara ica fastness was increased by mordanting treatment.

  • $TiO_2$ photocatalyst has been known to exhibit a notable disinfecting activity against a broad spectrum of microorganisms. A lot of commercial $TiO_2$ photocatalyst products have been developed for antimicrobial purposes. However, a standard method has not yet been proposed for use in testing antimicrobial activity. In this study, we developed a $TiO_2$ photocatalytic adhesion test method with film as the standard testing method for the evaluation of antimicrobial activity. This method was devised by modifying the previous antimicrobial products test method, which has been widely used, and considering the characteristics of $TiO_2$ photocatalytic reaction. The apparatus for testing the antimicrobial activity was composed of a Black Light Blue (BLB) lamp as UV-A light source, a Petri dish as the cover material, and a polypropylene film as the adhesion film. The standard $TiO_2$ photocatalyst sample, Degussa P25 $TiO_2$ - coated glass, could only be used once. The optimal initial concentration of the microorganism, proper light intensity, and light irradiation time were determined to be $10^6$ CFU/mL, 1.0 mW/$cm^2$, and 3 hr, respectively, for testing and evaluating antimicrobial activity on the $TiO_2$ surface.

  • HEVC RExt(High Efficiency Video Coding Range Extension)는 RGB/YUV 4:2:2 4:4:4 색 샘플링 영상과 10비트 심도 이상의 영상 지원을 목표로 한다. RGB 영상은 YUV 4:2:0 색 샘플링 영상과는 달리 색평면 간 높은 상관도를 갖고 있으며, 이를 이용하여 화소값을 예측하는 기법들이 JCT-VC 표준화 회의에서 기고되었다. 하지만 일반적으로 RGB 영상의 고주파수 성분은 색평면 간 낮은 상관도를 갖고 있으며, 이는 색평면 간 예측 시 부호화 효율 저하의 원인이 된다. 따라서 본 논문에서는 색평면 간 예측 시 고주파수 성분을 저역통과필터를 통해 적응적으로 제거하는 기법을 제안한다. HEVC RExt의 RGB 영상을 통한 실험 결과, 본 논문에서 제안하는 기법은 기존 색평면 간 예측 기법에 비해 큰 복잡도의 증가 없이 평균 0.6%의 BD(Bjontegaard Distortion)-율 이득을 얻을 수 있었다.

  • 1. Objective TS-QSCD (The Two-Step Questionnaire for the Sasang Constitution Diagnosis) is one of the self-reporting Sasang-Constitutional diagnosis questionnaires and one constituted by a two-step discriminant function. The process of TS-QSCD is as follows. During the first step, the testers are classified into two groups: the Yangin(陽人) group and Eumin(陰人) group. Following this, the Yangin group is divided into the Soyangin group and Taeyangin group likewise the Eumin group is divided into the Taeumin group and Soeumin group. This questionnaire has the merits of an ordinary questionnaire with four discriminant functions and a decision tree method. The purpose of this study is to evaluate and standardize TS-QSCD 2. Materials and Methods TS-QSCD was administered to 352 random informants who were examined by professionals. Reliability was tested by inter-item consistency using cronbach's ${\alpha}$, and validity was tested by a two step discriminant function. Cross tabulation Analysis was also used to look into the distribution of responses among the groups. 3. Result 1) The reliability of TS-QSCD was relatively valid. The internal consistency of TS-QSCD (AB) was cronbach's ${\alpha}$= 0.815, and TS-QSCD (AC) was cronbach's ${\alpha}$= 0.832. 2) There was a significant difference in points between Eumin group teens and other age groups, between those of Soeumin teens and other age groups. 3) TS-QSCD corresponded with the real Sasang constitution at the rate of 65.0%. When using 61 questions and four discriminant function as with ordinary methods, TS-QSCD corresponded with the real Sasang constitution at the rate of 74.9%. 4. Conclusion 1) TS-QSCD that complements the merits of existing questionnaires is effective in diagnosing Sasang constitutions. 2) Deleting duplicate questions is thought to be one of the reasons for the decreased validity rate. 3) The lower the validity of the first step, the more we should build up at each second steps a way to rescue the groups which were assigned wrongly during the first steps. 4) This standardization of TS-QSCD would be helpful in making a program for diagnosing the Sasang Constitution

  • BACKGROUND: An official analytical method was developed to determine etofenprox residues in agricultural commodities using high-performance liquid chromatography (HPLC). METHODS AND RESULTS: The etofenprox residue was extracted with acetone from representative samples of five raw products which comprised rice grain, apple, mandarin, cabbage, and soybean. The extract was then serially purified by liquid-liquid partition and Florisil column chromatography. For rice and soybean samples, acetonitrile/n-hexane partition was additionally coupled to remove nonpolar lipids. Reversed phase HPLC using an octadecylsilyl column was successfully applied to separate etofenprox from co-extractives. Intact etofenprox was sensitively detected by ultraviolet absorption at 225 nm. Recovery experiment at the quantitation limit validated that the proposed method could apparently determine the etofenprox residue at 0.02 mg/kg. Mean recoveries from five crop samples fortified at three levels in triplicate were in the range of 93.6~106.4%. Relative standard deviations of the analytical method were all less than 10%, irrespective of crop types. A selected-ion monitoring LC/mass spectrometry with positive atmospheric-pressure chemical ionization was also provided to confirm the suspected residue. CONCLUSION(s): The proposed method is simple, rapid and sensitive enough to be employed in routine inspection or monitoring of agricultural products for the etofenprox residue.
