This study is investigated for predicting a comfort region in the rectangular enclosure assumed Ondol cavity. Thermal environment is actually a combination of air temperature, mean radiant temperature, air velocity, humidity and two personal factors(clothing insulation and activity level) that will influence a person's perception of warmth or coolness. A comfort region is predicted by obtaining operative temperature(OT). The operative temperature is related with radiant and convective heat flux. The operative temperature of comfort region(thermal neutrality) is 20-24℃ at clo=0.1, met=1.2, RH=0%, -0.5<PMV<0.5 and PPD<10%. Radiant and convective heat flux is obtained for various adiabatic walls. This study is carried out a two dimensional numerical analysis by SIMPLER method. Radiant heat flux is obtained by a simplified zone analysis method. And shape factor is obtained by direct integral method.

The purpose of this study is to deal with the effective management of foreign exchange for improving profitability of tourism hotel, and specially to aim at the gap between the remittance to foreign banks and the collection from foreign banks. This study analyzed the number of foreigners in each deluxe hotel in Seoul, trade status of foreign exchange, and profit from money exchange. An analysis of remittance status of foreign exchange because of commission payment on the management skill from foreign hotel chains and the cost from hiring foreign general manager proves that first, deluxe hotel in Seoul just do their duties as a purchasing foreign exchange, second, cost rate is too high to exchange into Korean Won because they draw the money from foreign banks after purchasing traveler"s check, and third, there are some needless cost in sending the money to foreign banks which is needed for management of tourism hotel. This study has following limitation. First, there are some errors in collecting data and analyzing status because of statistics of the amount of money exchange is not computerized. Second, research objective is restricted as deluxe hotels only in Seoul. Third, American dollar is the key currency in many countries, so there are a lot of difficulties in analyzing status for the scope of money exchange. So, a study that can minimizes errors in collecting data is required and systematic and steady study is urgently needed.

본 증례는 50세 여성의 제 1형 신경섬유종 환자로서 척추 신경섬유종에 의해 초기 상완신경총 병변 소견을 보였다. 약 4개월 동안 후경부통, 좌측 견관절, 좌측 상완의 마비를 보였으며, 초기 전기진단학적 검사상 경수 5번과 6번 신경근을 중심으로 쇄골상부 신경절전성 상완신경총 병변이 관찰되었다. 그러나, 액와 자기공명영상, 초음파검사, 단순 방사선검사, 골주사 등의 영상학적 검사에서는 심한 흉추 척추 전-측만증과 경수 뇌경막에 확장 소견을 제외하고는 상완신경총 병변의 소견은 관찰되지 않았다. 7개월경과 후, 좌측 상지 및 양측 하지의 근력 저하, 경수 4번이하의 감각 저하, 경도의 흉통을 동반한 호흡곤란이 진행되었다. 응급으로 시행된 경수 자기공명영상에서 좌측 경수 3번과 4번에 경막내 액와-속질의 신경종양이 진단되었다. 수술적 처치를 시행하였으며, 거시적 관찰상 척수 신경섬유종이 진단되었다. 급격히 진행하는 척수 신경섬유종은 초기에 상완신경총의 신경근 병변의 소견을 보일 수 있으므로, 신경섬유종증 환자에서 상완신경총 병변의 진단에 세심한 주의를 요한다. We observed a patient with symptom similar to brachial plexus lesion caused by spinal neurofibroma in a 50-year-old female with a history of neurofibromatosis-1(NF-1). She presented with posterior neck, left shoulder and left upper arm paralysis of 4 months duration. The initial electrodiagnostic study(EDS) revealed supraclavicular preganglionic brachial plexus lesion of mainly involved left C5 and C6 roots. However, radiological imagings including axillar MRI, ultrasonography, cervical plain radiography and bone scintigraphy showed no definitive brachial plexus disease except cervical dural dilation and severe thoracic scolio-Iordosis. On 7 months after the first admission, she had aggravated muscle weakness on the left upper arm and both lower extremities, sensory impairment below C4 and respiration difficulty with the chest pain. Emergency MRI showed intradural axillar-medullary neurogenic tumor at the left C3-C4. Subsequently, the patient was treated with surgical resection. Grossly specimen examination displayed the presence of a spinal neurofibroma. In rapidly progressing spinal neurofibroma represented firstly as root lesion of brachial plexus in EDS, the physician should pay scrupulous care to evaluate the cause.

Objective : The aim of this study was to review systemically clinical trials on the effectiveness and safety of herbal medicines in the treatment of osteoarthritis. Methods : Computerized literature searches were carried out on seven electronic databases, and hand-searching on some chinese medical journals in library of Kyung Hee Medical Center. Trial data were extracted in a standardized, predefined manner and assessed independently. Results : 1. Thirty reports of clinical trials and two reports of meta-analyses concerning herbal medicine were collected and reviewed Among these reports three medical herbs were applied as topical medicine and others as internal medicine. 2. The western studies established NSAIDs or placebo as their control group. Five chinese reports established formulated herb pill(Ruanshnagshenjin pill) as their control group and Six did not establish a control group at all. 3. ACR was the most highly used diagnostic criteria in the western studies while the Chinese used their official criteria established by their government or the criteria of their text books. 4. 20 reports chose the Lequesne functional index, SHAQ, WOMAC OA index, AIMS, and their own unique scoring system as the criteria of analysing the effect. Others chose clinical symptoms, articular functions, and lab finding as their criteria. 5. 7 single herbs and 19 formulated herbs were studied. Among the formulated herbs, Achyranthes japonica was studied in 10 of the studies and Angelica gigantis Radix in 8, making them the most often studied herbs among the studies.
