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.

Perceptions and concerns of parents about elementary school lunch service were investigated by questionnaires in March, 1998. Five hundred and ten parents were selected randomly from schools in the city area, the rural area or the islands in Incheon Metropolitan city. 95% of parents preferred the school lunch service because nutritious food was available to the children regardless of family income or mother's occupation. Meal cost per capita was in the range of 1,000 and 1,200 won, which satisfied most parents (74%). Moreover, many parents (68.8%) were willing to pay extra money to support the school lunch program and they actually had such experiences (82.4%). More than 90% of the respondents wanted to be adviced about the menu. Subjects chose nutrition and sanitation (25%), taste (18%), and meal size (16%) as aspects of improvement in school lunches. Parents wanted to participate in serving foods, cooking, and washing dishes once (23%) or twice (31%) a year and they considered this as a good opportunity to join the school activities. 98% of parents showed very positive responses to the nutritional education provided by the school dietitian.

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.

이성대상포진의 증상에 따른 안면신경마비의 정도와 예후

신시옥,송창근,이동욱,최영석,진흥률,신정우,윤희석 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.1

연구목적: 이성대상포진에 동반되는 안면신경마비는 Bell's palsy와는 달리 예후가 더 나쁘고 그 마비가 완전히 회복되지 않는 경우가 더 많다.본 연구에서는 이성대상포진에서 발현되는 증상들의 유무가 치료 전 안면신경마비의 정도 및 치료 후 예후와 상관관계가 있는지를 관찰하여 예후의 예측인자에 대해 분석하였다. 재료 및 방법: 지난 1992년 1월부터 1999년 6월까지 이성대상포진으로 진단받고 본원에 입원하여 고용량 부신피질호르몬제와 항바이러스제인 acyclovir의 병합투여로 동일한 치료를 받은 30명의 환자를 대상으로 후향적으로 의무기록을 분석 및 고찰하였으며, 치료 전 안면마비의 정도와 치료 후 마비의 회복 정도를 이통, 이명, 난청, 현훈 등의 증상의 유무와 치료 시작 시기, 그리고 안면신경의 electroneuronography(ENoG) 값에 따라 비교하였다. 결과: 이성대상포진수포가 안면신경마비 보다 먼저 발현된 경우에 안면신경마비의 치료 전 grade가 통계적으로 유의하게 좋았다(p<0.05).이통, 청력손실, 그리고 현훈의 유무에 따른 안면신경마비의 정도는 상관관계가 없었고 예후에도 차이가 없었다.이명의 유무에 따른 치료 전 안면신경마비의 정도는 상관관계가 없었으나 치료 후 완전회복율은 이명이 있었던 군에서 통계적으로 유의하게 높았다(p=0.003<0.05).완전회복군과 불완전회복군 사이의 치료 전 ENoG의 수치는 통계적으로 유의하게 예후와 상관이 있었다(p=0.037<0.05). 결론: 좀더 많은 수의 환자를 연구에 포함하여 증상에 따른 예후의 차이를 연구하는 것이 필 요하며 또한 ENoG 값이 10%에서 40% 사이인 환자들의 치료 방법에 대한 고려와 이성대상포진수포가 안면신경마비보다 먼저 생긴 환자에서 치료 전 마비정도가 경미했던 이유에 대한 연구가 필요할 것으로 생각된다. Purpose: Herpes zoster oticus generally has a poor prognosis, leaving many patients with permanent facial nerve dysfunction, compare to Bell's palsy.Acyclovir and prednisolone have been widely used for the treatment of herpes zoster oticus.This retrospective study was conducted to suggest the prognostic factors according to various symptoms. Materials and Methods : Clinical studies were retrospectively performed on 30 patients with herpes zoster oticus who were treated with acyclovir and prednisolone in the Chungbuk National University Hospital between 1991 and 1999.The authors analyze the pre-treatment grade and prognosis of facial nerve palsy according to symptoms(the existence of otalgia, tinnitus, hearing loss, and vertigo), the treatment onset, and electroneuronography ( ENoG ). Results : Of thirty patients who have been diagnosed as herpes zoster oticus, there is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of vesicle, otalgia, tinnitus, vertigo, and hearing loss.Of 25 patients who have facial nerve palsy, the recovery from the palsy is complete in 14 patients(56%).There is no significant difference in the pre-treatment grade of facial nerve palsy according to the existence of otalgia, tinnitus, vertigo, and hearing loss.The pre-treatment grade of facial palsy is better when the vesicles precede facial in the group with tinnitus than without tinnitus.A significant difference of the prognosis according to the onset of treatment and other symptoms are not found.ENoG is better in the group that facial nerve palsy is completely recovered than incomplete recovery group. Conclusion : Reliable prognostic factor according to symptoms is not found, ENoG is the only prognostic factor.

정렬 및 탐색을 위한 효율적인 동적 알고리즘

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.
