This study investigates the influence of cane length on the weight distribution of the elderly in a standing position. Thirsty participants were evaluated using two different cane lengths based on measurements of distal wrist crease to ground (WC cane), and distance of greater trochanter to ground (GT cane). A limloader was used to determine the weight distribution on the subject. It was found that 6.5% of body weight was supported on a GT cane and 7.7% of body weight supported on a WC cane in a standing position. Results suggests that more weight is distributed on a WC cane than a GT cane in the elderly.

본 연구에서는 시판되고 있는 식초를 이용하여 6종의 식품 유해세균에 대한 항균력을 비교하였다. 그 결과, 감식초와 현미식초는 합성식초에 비해 S. aureus, M. luteus, S. enteritidis 및 E. coli에서 항균 활성이 높게 나타났으며, 현미식초가 감식초에 비해 식품유해세균에 대한 항균활성이 비교적 더 높게 나타났다. 현미식초의 농도에 따른 항균활성을 조사한 결과 5종의 그람양성 세균 및 음성 세균 모두 10μm/mL 이상의 농도에서 생육이 거의 억제되었으나, V. parahaemolyticus는 15 μm/mL 농도에서 생육이 거의 정지되어, 현미식초는 식품 부패균과 대장균 생육억제에 우수한 것으로 나타났다. 식초처리에 의한 미생물의 형태 변화를 전자 현미경으로 관찰한 결과 S. aureus, E. coli 모두 세포가 팽윤되고 일부 세포벽이 완전히 파괴된 형태를 관찰할 수 있어 식초처리로 인해 세균의 생육이 억제되는 것을 알 수 있었다. We investigated antimicrobial effects of commercial vinegar on the harmful food-born organisms. As a result, antimicrobial effects of brown rice vinegar showed stronger than persimmon and artificial vinegar. In 10μL/mL concentration of brown rice vinegar was completely inhibited about 5 strains except for V. parahaemolyticus, it was inhibited 15 μL/mL concentration. Therefore vinegars were effective for inhibition acitivity against foodborne organisms. S. aureus and E. coli treated with 25μL/mL concentration brown rice vinegar was observed by scanning electron micrographs(SEM). The cells were expanded and a part of cell wall was completely destructed by brown rice vinegar.

許聖雨,金永鈺 東亞大學校 附設 情報通信硏究所 1993 情報通信硏究所論文誌 Vol.1 No.1

정열 및 탐색은 자료 관리를 효율적으로 하기 위해 아주 빈번히 사용되는 연산이다. 그리고 많은 자료 구조 가운데 정렬과 탐색이 동시에 동적으로 가능한 자료구조는 이진탐색트리를 들 수 있다. 그러나, 이진탐색트리에서도 정렬된 결과를 얻기 위해서는 중위순회를 해야만 한다. 더구나 이진탐색트리로는 영역탐색이 불가능하다. 본 논문에서는 확장된 이진탐색트리인 K-트리를 제안하고, 이를 이용하여 중위순회를 하지 않고서도 정렬된 결과를 얻을 수 있는 알고리즘을 보인다. 또한 이 알고리즘을 이용하면 영역탐색도 가능함을 보인다. K-트리는 AVL-트리로 유지되기 때문에 새로운 노드의 삽입에 필요한 시간 복잡도는 O(log n)이다. 여기서 n은 기존 K-트리에 있는 노드의 갯수이다.

The results will contribute to the promotion of quality of life for elderly people. Method : The participants, 135 people over 60 years of age, were interviewed during January and February 2004. A questionnaire was used to collect the data. The measurement tools were the Loneliness scale developed by Kim (1997), the Self-esteem scale developed by Rosenberg and translated by Jeon (1974), the Health behavior assessment developed by Choi and Kim (1997). The data were analyzed using descriptive statistics, t-test, Pearson's correlation coefficients ANOVA, and multiple regression analysis. Result : The results of this study are as follows : Family type had a statistically significant correlation with health behavior, loneliness, and self-esteem in elderly people. Monthly income had a statistically significant correlation with health behavior in elderly people. Perceived health status had a statistically significant correlation with health behavior, loneliness and self-esteem in elderly people. There was a significant correlation between loneliness and self-esteem (r=-.531, p<.001), loneliness and health behavior (r=-.623, p<.001), and health behavior and self-esteem (r= .500, p<.001). Stepwise multiple regression analysis revealed that the predicting factors of health behavior were loneliness (38.8%) and self-esteem (4%). Conclusion : In conclusion, there exists a close correlation between loneliness, self-esteem, and health behavior. Especially, loneliness influences not only self-esteem but also health behavior in elderly people. The mediation of loneliness is a necessity for the improvement of physical and psychological health behavior.

Renal papillary necrosis occurs most commonly in association with urinary tract infection, diabetes mellitus, sickle cell disease, vascular disease, and analgesic nephropathy. Clinical presentation may be related to symptoms of pyelonephritis such as flank pain, renal colic, hematuria, Proteinuria, recurrent fever. The necrotic tissue may be sloughed off, and the diagnosis can sometimes be made by finding piece of renal medullary tissue in the urine. Pyelography may demonstrate cavities and sinuses in the resion of papillae. Anuria & oliguria can lead to the acute renal failure, and especially prognosis and progress may be affect influenced by urinary infection. We report a case of renal papillary necrosis with ingestion of bear gallbladder. On pyelography, Persistent contrast is diagnostic clue of renal papillary necrosis. This case is not be related to urinary tract infection, but occurred acute renal failure. Expectant treatment was gone.
