본 연구의 목적은 경상북도 영양군 수하계곡의 관속식물상을 조사 및 분석하여 생태․경관보전 지역의 관리와 생태탐방로 조성에 필요한 기초자료를 제공하는 것이다. 관속 식물상은 95과 258속 366종 9아종 28변종 4품종 1잡종 1재배 품종의 409분류 군이며, 식재종은 주목, 자작나무 등 7분류군이었다. 희귀식물은 태백제비꽃, 미치광이풀, 꽃창포, 노랑무늬붓꽃 4분류군, 한국 특산식물은 키버들, 노랑갈퀴, 지리대사초 등 8분류 군으로 나타났다. 식물구계학적 특정종은 총 37분류 군으로, Ⅳ등급은 3분류 군, Ⅲ등급은 10분류 군, Ⅱ등급은 8분류 군, Ⅰ등급은 16분류 군이었다. 기후변화 적응 대상 식물은 피나물, 산새콩, 애기며느리밥풀 등 11분류 군으로 나타났다. 외래식물은 소리쟁이, 달맞이꽃, 큰김의털 등 21분류 군이며, 생태계 교란식물은 돼지풀 1분류 군이었다.

The purpose of this study is to examine the feeding and nutritional status of enteral tube-fed elderly patients. Subjects included 77 elderly hospitalized patients who had received enteral nutrition more than one week before admission. Medical records on admission and actual feeding volume were used to assess anthropometric, biochemical, and nutritional status. Most patients manifested disorders of the nervous system (93.5%) and the average duration of tube feeding was 13.9 months. The average feeding volume of formula was 1,107 mL per day and the mean ratios of calorie and protein (supplied vs. required) were 81.7% and 80.9%, respectively. At admission, 57.4% of the patients were malnourished according to the institutional criteria. Patients receiving less than 80% of the required calories were in worse nutritional status compared with those receiving more than 80% of the required calories. Body mass index, percent ideal body weight, serum albumin level and blood lipid levels (total cholesterol, HDL-cholesterol, triglyceride) were significantly lower in patients receiving less than 80% of the required calories. These results indicate the high prevalence of malnutrition and the need for increased attention and nutritional care of elderly patients undergoing long-term enteral nutrition.
