The study was done to examine the effects of horticulture therapy on depression and stress in patient of hospice unit. The subjects of this study were hospice patient in D hospital in D city, thirty hospice patient were assigned to experimental group, thirty hospice patient were assigned to control group. Data were collected from . Horticulture therapy program consisted of indoor and outdoor horticultural activities. The horticulture therapy was conducted 30 minutes, 6 times a week for 3 weeks (a total 18 times). Measures were depression, and stress by serum cortisol count. Data were analyzed using descriptive statistics, chi-square test and t-test with SPSS/WIN 17.0 version. The results of this study was patients in the experimental group receiving Horticulture therapy had a significant difference in changes of depression between the experimental group and control group. The study results indicate that horticulture therapy is an effective, palliative intervention program to improve the depression and stress of hospice patients.
The purpose of this study was to develop the scale to measure job stress for school health teachers. Methods: It was performed through three steps. In the first step, open questionnaire was provided for 200 school health teachers to obtain subjective data on their job stress, based on which, 71 questions were created. In the second step, the 38 questions were developed by classifying through exploratory factor analysis of the first 71 questions and conducting pilot tests. In the third step, 26 questions were finally chosen through exploratory and confirmatory factor analysis, and verified the differences of school health teachers' job stress by general characteristics using this final scale. Results: Exploratory factor analysis was approved as the suitable factor analysis (χ 2 =3178.53, df=325, p=.000, KMO=.932). Confirmatory factor analysis showed acceptability of construct validity (CR>0.5, all factor), convergent validity, (CR, AVE more than marginal value),and discriminant validity (squared multiple correlation
요약본 연구는 상자성이며 중성자를 흡수하는 힘이 큰 gadolinium(Ⅲ) 전이금속과 polyaminocarboxylic ligand를 합성하여 제조한 MRI 조영제와 현재 임상에서 널리 사용되고 있는 Gd-DTPA의 영상을 비교하였다.
1.0T(Harmony, SIEMENS) MR 장비를 이용하여 Saline 100cc에 Diethylenetriaminetriacetic acid 유도체와
AbstractIn this study, image comparisons were carried out using a MRI contrast medium which was derived by mixing a polyaminocarboxylic ligand and a gadolinium (III) transition metal which is paramagnetic and has good neutron absorbing capabilities with Gd-DTPA which is currently being used widely in the clinical setting. By using a 1.0T (Harmony, SIEMENS) MR equipment, phantoms of which 100cc of saline was diluted with a diethylenetriaminetriacetic acid derivative and Gd-DTPA were imaged. The amount of diethylenetriaminetriacetic acid and Gd-DTPA which was diluted into the 100cc of.0mmol/L and 4.9mmol/L respectively. Head coils were used and while fixing the SE pulse sequence and image variable (as TE is 14ms, 1NEX with a 256x201 matrix), the signal intensity and simple contrast ratios according to changing concentrations and TR were compared with various TR at 300ms, 400ms, 500ms, 600ms, 700ms, 800ms, 900ms, 1000ms, 1200ms, 1400ms and 1600ms. According to the comparison results of the signal intensity of the image based on changes in contrast medium concentrations and TR, the differences in signal intensity between the two contrast mediums were found to be small at 1.0~2.0mmol/L when the highest signal intensity was achieved. However, at concentrations of 1.0mmol/L or less, the signal intensity was markedly higher in the Diethylenetriaminetriacetic acid derivative than in the Gd-DTPA complex. It was also found that the differences in the signal intensities demonstrated by the concentrations of the contrast mediums were affected by the TR. Accordingly, the efficacy of the Diethylenetriaminetriacetic acid derivative was shown to be better than the Gd-DTPA and also possible to get the optimum image quality by the use of an appropriate TR with appropriate concentrations of contrast medium.■ keyword :|Science Technology|Contrast Media|Gadolinium|Signal Intensity|
