목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

Thin film inductors of 10 mm×10 mm with inner coil type of 5 turns were fabricated by sputtering, photo-masking, and etching processes. The inductor has an inductance of 585 nH at 1MHz. And to estimate the applicability of the thin film inductors fabricated in this research to DC-DC converters. the test board of DC-DC converters was made. It was a boost type and input voltage of 2.7 to 5 volts. output voltage of 5 volts, and the switching frequency was 1.6 MHz. When the thin film inductor was adopted, the converter was operated normally. and the maximum efficiency was 49 % at the load of 50.5 Ω and the output power was 0.51 W. This result was not satisfactory for practical usage at present, but the switching FET devices for higher frequency use be developed in the near future, and then more higher frequency switching DC-DC converter will adopt these inductors.

Mucormycosis is an acute suppurative opportunistic mycosis that produce predominantly rhinocerebral disease in patient with diabetic ketoacidosis and immunosuppressed patient. We experienced two cases of rhinocerebral mucormycosis recently. The one occurred in patient with diabetic ketoacidosis and the other in acute leukemia. They showed nasal discharge, orbital cellulitis and proptosis. Their condition rapidly deteriorated. Biopsy from palate and sinus revealed broad, nonseptate, right-angled branching hyphae, a finding compatible with mucormycosis.

Characteristic components of the injury include : 1. Male to female ratio was 2.7 : 1, and the most prevalent age was 21 to 40 years. 2. Multiple level injuries were 6 cases (27.3%), and the most common cause of injury was fall down(14 cases, 63.6%). 3. The most cammon location was L1(45.5%) 4. The most common pattern of the retropulsed fragment in burst fracture was single midline fragment type(14 cases, 63.6%) and the most common type of burst fracture was classical form(10 cases, 45.5%). 5. Posterior element involvement of vertebra was seen in Ⅱ cases(50%) and the most common finding was laminar fracture in 9 cases. 6. The degree of anterior wedging above the 50% in height of vertebral body was in 4 cases (18.2%). 7. Degree of spinal canal narrowing and degree of neurological impairment is not directly correlated.

백서 척수에서 Capsaicin과 Eugenol이 iCGRP (immunoreactive calcitonin gene-related peptide) 분비 조절에 미치는 영향

오원만,김원재,최남기,박상원,황인남,김선현 大韓齒科保存學會 2001 Restorative Dentistry & Endodontics Vol.26 No.5

Neuropeptide such as calcitonin gene-related peptide and substance P may mediate neurogenic inflammation, but little is known about the regulation of neuropeptide release from rat spinal cord. Eugenol has been reported to reduce odontogenic pain and is known to have a structure similar to capsaicin, a potent stimulant of certain nociceptors. This study was done to examine the effect of capsaicin and eugenol on immunoreactive calcitonin gene-related peptide (iCGRP) release from rat spinal cord and whether eugenol regulates capsaicin-sensitive release of iCGRP or it evokes capsaicin-sensitive release of iCGRP. The dorsal half of rat lumbar spinal cord was chopped into 200㎛ slices. They were superfused (500㎕/min) in vitro with an oxygenated Kreb's buffer. The EC50 of capsaicin on iCGRP release was measured. Eugenol (600㎛ and 1.2mM) and vehicle (0.02% 2-hydroxyl-β-cyclodextrin) were administered prior to stimulation of rat lumbar spinal cord with capsaicin. The amount of iCGRP release from rat lumbar spinal cord was measured by radioimmunoassay. The results were as follows : 1.iCGRP release from rat lumbar spinal cord was dependent on concentration of capsaicin. The EC50 of capsaicin on iCGRP release was 3㎛. 2.In the vehicle treated group, capsaicin (3㎛) evoked a 14-fold increase over basal iCGRP level. 3. Administration of 600㎛ and 1.2mM eugenol evoked a 2.2-fold increase and a 2.3-fold increase over basal iCGRP level respectively. 4.Administration of 600㎛ and 1.2mM eugenol increased capsaicin evoked release of iCGRP by more than 50%. These results indicate that eugenol evoke CGRP release from central nervous system and potentiate the pain-inducing action of capsaicin on it Key words : Eugenol, Capsaicin, Rat lumbar spinal cord, Superfusion, Radioimmunoassay

建築企劃段階에서 經濟的 妥當性 分析을 위한 기초적 연구 : 建築의 Cost-Benefit Analysis 적용을 중심으로 Focused on Cost-Analysis in Architecture

오승준,전재열 단국대학교 1999 산업기술연구 Vol.1 No.-

C/B analysis technical begins with a balance ; a simple definition induced from the benefit result form construction unit price and rental income. The project is feasible if the estimated benefit exceeds the investment cost. We can see from this thesis that the cost can be redefined as project budget, on the other hand, benefit can be started as an investment value or a present value. Especially architects and developers must be aware that a raise in or a reduction of the budget are not adequate answers for the success of the most effective and rational project modification. In this thesis, I logically try to solve the analysis technique by use of more complicated elements, data, and clarify the relations between cost and benefit. However, I think a profound factor analysis must be followed.

We present a case of angiomyofibroblastoma of the vulva in a 32-year-old woman. The asymptomatic lesion measured 4×3cm and appeared as a gray-white myxoid mass on cut sections Histologically, it appeared as a relatively well-circumscribed spindle cell proliferation with alternating hypercellular and hypocellular areas and proliferation of thin-walled blood vessels. Immunohistochemically, the stromal cells expressed vimentin, CD34 and progesterone receptor, but not desmin, α-smooth muscle actin, S-100 protein and estrogen receptor. These features were similar to those of angiomyofibroblastoma as previously reported in the vulva except negativity for desmin A case of pathologically proven very rare tumor of angiomyofibroblastoma of the vulva is presented with a literature review

The purpose of this study was to establish Korean normas that will be valuable aids for diagnosis in orthognathic surgery patients. Lateral cephalometric measurements were established for adult Koreans (60 males, 62 females) with normal occlusion and acceptable profiles. The results were as follows: 1. Means, standard deviation and sexual differentiation were included within each measurement. 2. In skeletal mesurements, FH to SN and SN to mandibular plane measurements in females were larger than those in males while all linear measurements in males were larger than those in males were larger than those in females. 3. Significant differences were observed between male and female groups on all of the items that showed vertical relationship in dental measurments. And the measurements of ADH, PDH and overbite in males were larger than those in females while the measurements of incisor exposure in females were larger than those in males. 4. In all measurements of soft tissue except NLA, that is, of FCA, UFH, ULL and LLL, males were larger than those in females.
