The purpose of this study was to analyze walking steps to prevent unnecessary energy consuming and prevention of injury from sliding when someone was walking. The questionnaire, high speed video system, E.M.G. system, and force platform system were used to analyze sliding mechanism in biomechanical perspective. Several results were found as following: 1. According to questionnaire regarding sliding, 93.3% of participants have sliding experiences. People have sliding experiences by greasy floor(48.4%) and obstacle (22.5%). Sliding types were found from different kinds of shoes such as sneakers (48.8%) and boots (34.2%). The results were presented as following 44.6% of participants were fall down front direction and 40.3% of people fell down rear side. 2. According to the high speed video system analyzer, step sliding increased with increasing step speed from distance and acceleration speed experiment with 80 steps/min, 100 steps/min, 120 steps/min. Also, the most sliding were occurred with sneakers, boots, and bare feet as order. 3. According to E.M.G. test results, the vastus lateralis M., the vastus medialis m., and the tibialis anterior m. of electric action potential presented strongly when participants fell front, rear, and right side. The vastus lateralis m. and the tibialis anterior m. of electric action potential presented strongly when someone fell left side, but the vastus medialis m. and the gastrocnemius m. of electirc action potential presented as weaker. 4. According to the force platform test results, the most big change of floor antipower of x-axis presented when someone fell the left side. The most of big change of floor antipower of y-axis presented when someone fell down rear side. The most of big change of floor antipower of z-axis presented similarly when someone fell the front, rear, left, and right side.

The distributed species and the kinds of variable microorganism in Pharynx were monitored to the elementary school child. Our purpose was to investigate the distribution of bacteria in Pharynx of child except for adults. Analysis performed the collected sample from 15 students in Chungnam area for 2 days from July 30 to July 31 in 2012. The isolated bacteria were identified by Gram stain and biochemical test using VITEKⅡsystems. The experiment on microorganism concentration of contact parts carried out and the average of total microorganism was measured. The elementary child's Pharynx were isolated and identified. The isolation rates were major distributied to Gram positive cocci, another Gram negative bacilli and Gram positive bacilli. respectively. The frequently isolated bacteria were G. adiacens. The Granulicatella adiacens is one of the fastidious Gram positive cocci previously described as nutritionally variant streptococci due to their requirement of L-cysteine, pyridoxal, or thiol compounds for growth. These bacteria have been identified as significant causative agents of endocarditis, opthalmic infections, and meningitis. Further systematic studies are necessary with an emphasis on species identification. Key Words : Microorganism, Elementary child, Pharynx and Larynx

This study is to suggest useful basic data for the future dwelling unit plan, with systematic analysis of the dwelling description change in medium·large sized apartment houses. As results of analyzing change of net areas and bedroom' numbers of apartment houses in Seoul and the suburb by decade after 1970's, the net areas of units are increased and bedroom's numbers of unit are decreased as decades come recently. These are caused by the increasing of household income and the extension of living culture. It is forecasted that the scale of future apartment house unit will be expanded, and that increase of each space and separation of other room will be raised instead of increasing of bedroom's numbers.

The excessive initial corrosion rate of Mg is a critical limitation in the clinical application of biodegradable Mg implantsbecause the device loses its fi xation strength before the fractured bone heals. This study suggests a new approach to overcomethis hurdle by accelerating tissue regeneration instead of delaying the implant biodegradation. As angiogenesis is anessential process in early bone regeneration, a Mg implant coated with electrospun nanofi bers containing nitric oxide (NO),which physiologically promotes angiogenesis, is designed. The integrated device enables adjustable amounts of NO to bestored on the NO donor-conjugated nanofi ber coating, stably delivered, and released to the fractured bone tissue near theimplanted sites. An in vitro corrosion test reveals no adverse eff ect of the released NO on the corrosion behavior of the Mgimplant. Simultaneously, the optimal concentration level of NO released from the implant signifi cantly enhances tube networkformation of human umbilical vein endothelial cells without any cytotoxicity problem. This indicates that angiogenesis canbe accelerated by combining NO-releasing nanofi bers with a Mg implant. With its proven feasibility, the proposed approachcould be a novel solution for the initial stability problem of biodegradable Mg implants, leading to successful bone fi xation.

Mirizzi's syndrome is a rare complication of the gallstone disease, characterized by narrowing of the common bile duct (CBD) due to chronic extrinsic compression of an impacted gallstone in the cystic duct or the neck of the gallbladder. The impacted gallstone may erode into the bile duct, causing cholecystocholedochal fistula. The patients generally have history of repeated attacks of jaundice and abdominal pain. But there is no report about asymptomatic Mirizzi syndrome with cholecystocholedochal fistula which were found incidentally. So herein we present our clinical experience with a case of asymptomatic Mirizzi syndrome with cholecystocholedochal fistula in a young female.

Wernicke's encephalopathy is characterized by the triad of ocular symptoms, ataxia, and mental confusion and neuropsychiatric condition generally caused by acute thiamine deficiency. Although it is common in the severe alcoholics, several other causes also have been identified, such as total parenteral nutrition (TPN) use, hyperemesis gravidarum, anorexia nervosa, hemodialysis, uremia, and acquired immunodeficiency syndrome(AIDS). Chemotherapy in patient with malignanacy and long term total parenteral nutrition following bone marrow transplantation are related with Wernicke's encephalopathy. A 48-year-old woman had been treated with Daunorubicin and Cytarabine for remission induction chemotherapy of acute myeloblastic leukemia and intravenous hyperalimentation due to persistent hematochezia and ileus caused by infiltration of leukemic cell in terminal ileum. She suddenly complained of diplopia, tremor, and mental confusion at 32th day after chemotherapy and generalized tonic-clonic seizure at 34th day after chemotherapy. The diagnosis of Wernicke's encephalopathy was made with clinical presentations and brain MRI. Brain MR T2-weighted & Flair image revealed a high signal intensity lesions bilaterally at the medial thalamus and peri-acueductal grey matter of the midbrain. The patient was successfully treated with vitamin B1. We presented a case of acute Wernicke's encephalopathy developed after remission induction chemotherapy followed by intravenous hyperalirnentation in a patient with acute myeloblastic leukemia.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about ‘Table etiquette’, ‘Reasons for eating fruits and vegetables’ (78.7%), ‘Food waste and environment’ (72.3%), ‘Healthy snacks’ (55.7%), ‘Food sanitation’ (52.3%), ‘Food culture of foreign countries’ (48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about ‘basic food preperation’ (p < 0.01). They had learned ‘Nutrients for body’ and ‘Food waste and environment’ in school, ‘Healthy weight loss’, ‘Food culture of foreign countries’, ‘Food circulation’ on television, Most content (‘Table etiquette’, ‘Simple cooking’, ‘Food sanitati n’, ‘Eating behaviors for health’, ‘Reasons for eating fruits and vegetables’, ‘Healthy snacks’) was learned from parents. The practice after nutrition education was higher in ‘Table etiquette’ (2.14), ‘Eating fruits and vegetables’ (2.07) than others compared with education experience. The most reason of non-practice on nutrition information was ‘Troublesome’. In ‘Nutrients for body’, a boy answered ‘Difficult for practice’ 20.0%, a girl answered ‘Difficult to understand’ 32.6%, showing a significant difference between the gender groups (p < 0.001). They remembered the ‘Nutrients for body’ (49.6%), ‘Food sanitation’ (44.5%) because of ‘important content’,‘Basic food preparation’ (40.6%), ‘Food culture of foreign countries’ (36.3%) because of ‘interesting content’, ‘Healthy weight loss’ (52.0%), ‘Eating behavior for health’ (44.5%) and ‘Healthy snacks’ (33.7%) because of ‘need for my health’.

목적: 급성 파종성 뇌척수염은 감염이나 예방 접종 후 발생하는 중추 신경계의 급성 자가 면역 염증성 질환으로 탈수초를 일으킨다. 신경학적인 증상으로 발현되고 대부분 환전히 회복되지만 신경학적 후유증을 남기거나 사망 할 수도 있다. 이에 저자들은 본원에서 발생 한 14명을 분석하여 조기 진단과 치료에 도움을 주고자 하였다. 대상과 방법: 1998년 3월부터 2003년 8월까지 이대목동병원에서 급성 파종성 뇌척수염으로 진단 받은 14명의 의무기록을 후향적으로 조사하였다. 결과: 환자들의 평균 발생 연령은 5±7.8개월이였고, 특정계절이나 연도에 집중되어서 나타나지는 않았다. 선행질환은 주로 비특이적인 상기도 감염이 가장 많았고, 초기증상으로는 경련이 가장 많았다. 그 외에 의식저하나 운동장애도 있었다. 뇌척수액 검사에서 백혈구 증가증이 발견된 경우는 있었으나 단백이 증가된 경우는 없었다. 뇌 자기공명 촬영에서 T2 증강시 뇌백질과 기저핵에 고음영의 다발성 병소가 발견되었고 추적 촬영에서 대부분에서 소실되었다. 뇌파 검사가 시행되었던 경우 전반적인 서파가 가장 많았고 국소적인 극파가 나온 경우도 한 명 있었다. 환자들은 정맥 면역 글로블린과 메틸프레드니졸론으로 치료하였고 치료 시작 후 3~7일내 증상이 호전되었다. 모든 환자를 2달 이상 추적 관찰하였고 항경련제가 지속적으로 필요한 정도의 경련성 질환이 두 명, 신경아교증이 남아잇는 경우가 한 명, 외래에서 다발성 경화증이 의심되는 경우가 한 명 있었다. 결론: 급성 파종성 뇌척수염은 침범 부위에 따라서 다양한 임상 상으로 나타나며 면역 글로블린과 메틸프레드니졸론이 치료에 효과적이였다. 본 연구에서는 대상 환자수가 적어 신경학적 후유증의 위험요소는 밝힐 수는 없으나, 예후는 검사소견과 연관되어 있지는 않았고, 대부분에서 양호하여 완전히 회복되었으나, 신경학적 후유증이 남은 경우도 있었다. Objective:Acute disseminated encephalomyelitis(ADEM) is an acute demyelinating autoimmune inflammatory disease of the central nervous system which develops after infection of vaccination. It may be fatal, and produce a permanent residual static disability or fully recover. We retrospec-tively studied 14 cases to investigate the clinical findings and outcome of ADEM. Methods : 14cases of ADEM diagnosed at Ewha Womans University Mokdong Hospital from 1998 to 2003 were retrospectively reviewed. Results : The age of onset was 5years±7.8 months and no seasonal clustering was found. The time of onset of symptoms was between 3 to 30 days. The preceding events were nonspecific upper respiratory infections in 9 cases, aseptic meningitis in 4 cases, and gastroenteritis in one case..The initial symptoms were seizure, altered consciousness, hemiparesis, fever, headache, and vomiting. Brain MRI showed multifocal high signal intensity lesions on T2 weighted image mainly in the cerebral whith matter, basal ganglia and periventricular white matter. EEG was performed in some cases and showed generalized or focal slow waves and only one case showed focal spikes. Patients were treated with IV globulin and methylprednisolone and the symptoms improved within 3-7 days after treatment. All patients were followed up for more than 2 months and most of them fully recovered except two. Conclusion : ADEM presents in various clinical manifestations depending on its involvement of the brain lesions. Most cases recovered fully but in some cases, residual permanent neurologic sequelae remained.
