연구의 필요성대한대장항문학회는Purpose: This study aimed to investigate nutritional risk, physical activity, and quality of life (QoL) and the interaction of these factors in colorectal cancer patients. Methods: Participants were colorectal cancer patients receiving follow-up treatment at the colorectal cancer outpatient clinic of Severance Hospital in Seoul. Participants were recruited from October 25 to November 30, 2010. The survey questionnaire consisted of Nutritional Risk Score (NRS), International Physical Activity Questionnaire (IPAQ) and Functional Assessment of Cancer Therapy -scales for Colorectal Cancer (FACT-C). Results: NRSs were significantly higher in patients with low BMI (F = 18.63, p< .001) and those who were underwent colorectal surgery within 1 month (F = 5.96, p < .001). Physical activity level of the participants was 28.96METs. Lower nutritional risk was associated with a higher QoL (r = -.34, p < .001). In a multiple regression analysis, the predictors of QoL were the age, economic status, and nutritional risk of the patient (R 2 = 40.0%). Conclusions: Targeted tailored nursing interventions are needed to assess nutritional risks in order to improve colorectal cancer patients' QoL.

Water supply safety index plays an important role on assessing the water supply capacity of hydrologic system. Due to the absence of consistent guidance, however, practical problems have been brought up on data period used for dam design and performance evaluation. Therefore, this study employed bivariate drought frequency analysis which is able to consider drought severity and duration simultaneously, in order to evaluate water supply capacity of multi-purpose dams. Drought characteristics were analyzed based on the probabilistic approach, and water supply capacity of five multi-purpose dams in Korea (Soyang River, Chungju, Andong, Daecheong, Seomjin River) were evaluated under the specific drought conditions. As a result, it would be possible to have stable water supply with their own inflow during summer and fall, whereas water shortage would occur even under the 1-year return period drought event during spring and winter due to low rainfall.
