Purpose: To identify the risk factors of falling in stroke patients. Method: Data collection was performed from the 438 stroke patients' medical record using. A questionnaire developed by the authors to survey falling. Data were analyzed by SAS program, through which the frequency, percentage, mean, standard deviation, t-test and x^(2)-test, and multiple logistic regression analysis. Results: The falling rate of subjects during their stay at the hospital was 14.2%. The length of stay was longer and the morbidity duration of stroke was shorter in the falling group than in the non-falling group. The risk of falling was 6.4 times higher in those who had experienced falling within 1 year before admission, 3.4 times in those with depression, 2.9 times in those with irritability, 2.0 times in those with urinary dysfunction, 5.7 times in those who used a quad cane in walking, and 3.3 times in those who used a walker. Conclusion: The risk factors of falling in stroke patients admitted to geriatric hospital include experience in falling, accompanying diseases and symptoms, walking level and assistive device used in walking. It is necessary to analyze the causes of falling based on results of the present study and to develop positive nursing interventions to prevent falling.

This study analyzes the validity of the tasks in Test of oral Proficiency (TOP) and Test of Writing Proficiency (TWP) as means of evaluating advanced-level high school students' English proficiency in a nation-wide English contest. For this purpose, both quantitative and qualitative analyses were conducted. The results show that all the tasks are statistically valid except for Task Ⅰ (Answering simple questions) for Group Ⅱ (who have stayed overseas longer than one year). The examination of students' recorded responses for TOP reveals how differently Groups Ⅰ and Ⅱ responded to the tasks and what can be done to improve task questions. Based on the findings, we suggest that for TOP, the current format be maintained for Group Ⅰ (who have stayed overseas shorter than one year). For Group Ⅱ, however, a modified use of TOP or its replacement with interviews is recommended. For TWP, since Task Ⅰ (Summary) and Ⅳ (Free writing) among the four tasks are very effective to measure students' writing proficiency, we recommend to use these two tasks alone instead of using all four of the tasks. We also suggest that a thorough training and detailed guidelines be provided for raters.

이예식,임홍미 경북대학교 사범대학부속 중등교육연구소 2005 중등교육연구 Vol.53 No.3

최근 정보화 · 세계회의 추세로 국내 영어교육 환경은 급격한 변화를 겪고 있으며 대부분의 대학들도 기존의 형식적인 대학영어교육에 탈피하기 위해 노력하고 있다. 이에 본고는 교양영어교육의 실태파악과 설문조사를 통한 학생들의 요구와 기대치를 수렴하여 현행 교양영어교육의 문제점과 개선방향을 모색한다. The purpose of this study is to examine the present state of general English education and to discuss how to improve the general English programs in order that the students can get better equipped with English proficiency. For this purpose, students of A university were questionnaired. The results of this questionnaire shows that most of the students recognized that learning English is very important and necessary in college education. Furthermore, they weren't satisfied with the current general English programs, pointing out several problems that should be further improved. Some recommendable suggestions based on the questionnaire are summarized as follows: First, the basic goal of the general English education should be to teach students "four skills" to improve their English communicative abilities. Second, we should change the general English courses into compulsory ones, increasing credit hours in order that students can have more opportunities to be exposured in the English environments. Third, we should place students of the same or similar proficiency level in one class, reducing the class size with a view to promoting more interaction between students and the instructor. Forth, we should offer a variety of general English courses. So students can choose the courses such as ESP/EAP-based education so as to satisfy the needs of each student. Fifth, we should provide many kinds of technological aids to encourage the students to willingly and positively participate in class. Finally, we should establish an authorized department to manage and supervise effectively the general English education program.

In order to investigate effects of krill on lipid components of liver and heart in cholesterol and cadmium-fed rats, male Sprague-Dawley rats were raised for 4 weeks with 8 experimental diets. Krill used in this experiment contained 65.4%(w/w) of protein and 16.7% of lipid. Krill contained 35% of polyunsaturated fatty acids and more unsaturated fatty acids than saturated fatty acids by 2 times. Amino acid content of krill was high in order of Glu, Asp, Tyr and Lys. Rats fed krill diet showed more food intake and weight gain compared with control group. However, food efficiency ratio and weight of liver and heart were not significantly different. The ingestion of cadmium resulted in a severe restriction in growth rate with normal or mild reduction of liver and heart weight. Cadmium also caused a significant decrease in food efficiency ratio. The contents of total and free cholesterol of liver and heart in rats fed krill diets were similar or slightly higher than those fed control diet. Dietary krill also showed no significant difference in liver and heart cholesterol levels in rats with cadmium ingestion. The contents of phospholipid and triglyceride in liver and heart of krill group were slightly higher than those of control group. Supplement of krill reduced triglyceride content of liver in rats ingested with cadmium without any effect on the level of phospholipid and heart lipids. The concentration of cadmium in plasma significantly increased with dietary krill. However, the krill supplement did not influence the concentration of cadmium in liver or heart. A significant accumulation of lipid in liver tissue was observed in all dietary groups but standard group. However, no difference in degree of lipid accumulation was found among the dietary groups. Necrosis and hemolysis of liver in all dietary groups were not shown.

단체급식소 12개소의 식단을 수거하여 각 메뉴별 및 1인분 식단별 NA 함량을 분석하였고 인공소화 기법을 활용하여 체내에서 생성 가능한 NA의 함량을 예측하였다. 육류와 어패류를 주재료로 요리된 메뉴들의 인공소화 전·후 NA 함량을 분석한 결과 멸치볶음에서 NDMA 함량이 흔적량 ~ 4.8 ㎍/kg으로 가장 높았고, 채소류를 주재료로 한 메뉴들에서는 불검출에서 흔적량의 NDMA가 정량되었으며, 인공소화 후에도 흔적량 이하로 정량되었다. 1인 분량의 식사를 수거하여 인공소화 전·후의 NA를 분석한 결과 NDMA는 인공소화 전 0.20 ~ 0.78 ㎍/kg의 범위였으나 인공소화 후에는 0.43 ~ 0.80 ㎍/kg으로 약간 증가하였다. 상기의 분석 결과를 기초로 하여 성인 1일 NA 섭취량을 계산한 결과 0.60 ~ 2.34 ㎍/day/person이며, 인공소화를 통한 체내에서의 생성량을 고려하면 최대 5.15㎍/day/person으로 추정된다. N-nitrosamine (NA) contents depending on simulated gastric digestion were analyzed with 12 kinds of diets collected from institutional food service those diets were estimated the total NA amounts including both intake from food directly and its endogenous formation in human body from simulated gastric digestion. NA was determined in dishes of meats, fished and vegetables before and after simulated gastric digestion. N-nitrosodimethylamine (NDMA) contents were from not detected(ND) to 4.8 ㎍/kg in dishes of meats and fishes. After digestion, its contents increased and the highest level was 3.0 ㎍/kg in panbroiled dried anchovy. In vegetable dishes, NDMA was detected as ND ~ trace before and after digestion. The contents of NDMA in diets collected from institutional food service were 0.20 ~ 0.78 ㎍/kg, 0.43 ~ 0.80 ㎍/kg before and after digestion, respectively. The average intake of Na per day to Korean, based on the above data, was 0.60 ~ 2.34 ㎍/day/person. The maximum daily intake of NA was reduced to 5.15 ㎍/day/person when considering NA amounts formed endogenously by simulated gastric digestion.
