As sloped farmland is subject to runoff and soil erosion and consequently require appropriate vegetative coverage to conserve soil and water, a field study was carried out to evaluate the impact of crop canopy coverage on soil loss and runoff from the experimental plot with three different textural types (clay loam, loam, and sandy loam). The runoff and soil loss were examined at lysimeters with 15% slope, 5 m in length, and 2 m in width for five months from May to September 2009 in Suwon (37° 16" 42.67" N, 126° 59" 0.11" E). Red pepper (Capsicum annum L. cv. Daechon) seedlings were transplanted on three different dates, May 4 (RP1), 15 (RP2), and 25 (RP3) to check vegetation coverage. During the experimental period, the vegetation coverage and plant height were measured at 7 day-intervals and then the "canopy cover subfactor" (an inverse of vegetation cover) was subsequently calculated. After each rainfall ceased, the amounts of soil loss and runoff were measured from each plot. Under rainfall events >100 mm, both soil loss and runoff ratio increased with increasing canopy cover subfactor (R²=0.35, p<0.01, R²=0.09, p<0.1), indicating that as vegetation cover increases, the amount of soil loss and runoff reduces. However, the soil loss and runoff were depending on the soil texture and rainfall intensity (i. e., EI30). The red pepper canopy cover subfactor was more highly correlated with soil loss in clay loam (R²=0.83, p<0.001) than in sandy loam (R²=0.48, p<0.05) and loam (R²=0.43, p<0.1) plots. However, the runoff ratio was effectively mitigated by the canopy coverage under the rainfall only with EI30<1000 MJ mm ha<SUP>-1</SUP> hr<SUP>-1</SUP> (R²=0.34, p<0.05). Therefore, this result suggested that soil loss from the red pepper field could be reduced by adjusting seedling transplanting dates, but it was also affected by the various soil textures and EI30.

N/A Color reproduction capability is represented by Q factor(quality value), and that of color scanner depends on its spectral response. When this spectral response of color scanner has linear transform relations to reception of human visual system, it has high Q factor. In this paper, color correction filter is designed using closest color mixture curve in order to improve color quality value in color scanner. And color reproduction capability of the scanner which has above filiter is tested theoretically by means of spectrum analysis. We have used McBETH color checker for standard color samples in spectrum analysis and calculated color deviation (△E_Lab) in Lab color space. The results are RED=0.95, GREEN=0.99, BLUE=0.96 in color quality value and average color deviation(△E_Lab) for 135 Munsell color sample is about 2.3.

PURPOSE : This study purposed to examine the relation between nursing college students' major satisfaction and their nursing professionalism. METHOD : We collected data from 197 nursing students at a college in Seoul using a structured questionnaire from the 6th to 13th. The collected data was analyzed by SPSS 17.0. RESULT : 1. The mean score of major satisfaction was 3.54±49 and that of nursing professionalism was 3.52±46. Among the sub-areas of major satisfaction, satisfaction with career investigation was highest. In addition, among the sub-areas of nursing professionalism, the specialty of nursing was highest. 2. Major satisfaction was higher in those from the Department of Natural Science, with a nurse in their family members and it was also significantly different according to the motive for choosing nursing. Nursing professionalism was higher in those with a nurse in their family members and it was also significantly different according to the motive for choosing. 3. A statistically significant positive correlation was observed between the subjects' major satisfaction and their nursing professionalism. The sub-area of major satisfaction in the highest correlation with nursing professionalism was 'satisfaction with perception', and the sub-area of nursing professionalism in the highest correlation with major satisfaction was 'professional self-concept' CONCLUSION : A significant positive correlation was observed between major satisfaction and nursing professionalism, and this raises the necessity for maintaining high major satisfaction so that nursing students may establish positive nursing professionalism through their college study.

Purpose: The purpose of this study was to examine the correlation of alcohol use disorder, social support and depression of the college students. Method: In this descriptive design study, 334 university students were recruited through convenient sampling from October, 2015 to January, 2016. Questionnaires used for online Google docs were AUDIT-K(Alcohol Use Disorders Identification Test-Korea), MSPSS(Multidimensional Scale of Perceived Social Support) and SDS(Self - Rating Depression Scale). Data were analyzed with descriptive statistics, independent t-test, one way ANOVA with Scheffe's test, and Pearson’s coefficient using SPSS 22.0 program. Result: 230 students of the 334 college students(68.8%) were classified into alcohol use disorder group. There was a significant correlation between the degree of social support and depression among all participants(r=-.45, p=.000). However, there was no correlation between alcohol use disorder and depression(r=.23, p=.006) and between alcohol use disorder and social support(r=.02, p=.758). Conclusion: This study showed a relationship between social support and depression, not the alcohol use disorder. This result can be used as the basic data in nursing research about alcohol use disorder, social support and depression of college students. Also, Further researches are needed to examine the factors that affect alcohol use disorder of college students, as well as depression and social support.
