천황봉에서 발원하여 산간 계류를 형성하고 흐르다가 유성천과 합류해 금강으로 유입되는 계룡산 동학사 계곡의 수선곤충 군집을 조사한 결과 총 5목 17과 37종이 출현하였다. 이중에서는 하루살이류가 6과 14종으로 가장 많이 출현하였으며, 현존량은 파리류가 전체 1,165개체중 569개체(48.84%)로 가장 높게 나타났다. 전체 우점종은 꼬마하루살이와 깔다구류로 0.15의 우점도지수를 기록하였다. 종다양도는 제 4지점인 남매탑 계류의 합류점이 0.93으로 가장 높았고, 제 1지점인 은선산장 위 부근이 0.09로 낮게 나타났다. 각 지점별 오수생물계열은 초강부수성-강부수성으로 매우 낮게 조사되었다. Aquatic insect communities were investigated in a mountain streams of YIt. Iiyeryong1 one of the central areas of Korea, from March to September, 2002. As a result, 37 species of aquatic insects in 17 families and in 6 orders appeared during the study period, the order Ephemeroptera and Diptera of which were the most appeared. Ephemeroptera was consisted of 14 species of 6 families, and Diptera was consisted of 589 individuals(48.84%j of total individual nun-her. Dominant species was Baetis ther-micus and the subdominant species was Chironmidae sp.. Dominant species index of Baetis thermicils and Chironmidae sp. was O.15 The highest species diversity index was observed of site 4 as 0.93 and the lowest species diversity index was observed of site 1 as 0.09. Dominance indices ranged between 0.15 and 1.00 while diversity indices between 0.09 and 0.93. In relation to species diversity indices, Mt. Iiyeryong streams were determined as Isosaprobity-Polysaprobity area. In general, it is inferred from the aquatic insect community that typical mountain streams of Korea are low.

이남용,고재현,백경란,송재훈,천정학,김성민,이혁,김수정 대한감염학회 1997 감염 Vol.29 No.6

저자들은 평소 건강하였던 환자에서 동물과의 접촉없이 P.multocida에 의한 세균성 심내막염이 발생하여 임상 경과 중 다발성 뇌경색이 합병되었으나, 항균제 투여만으로 완치가 되었던 증례를 경험하였기에 문헌 고찰과 함께 이를 보고하는 바이다. In recent years, an increasing number of infections with Pasteurella multoida in human have been reported, causing a wide range of systemic illness. Infective endocarditis with P.multocida, however, is still quite rare. Recently we experienced a cases of P. multocida endocarditis in a 26-year old man who was admitted because of fever and headache. He denied any recent contact with animals. P. multocida was identified from blood cultures and echocardiography showed mitral regurgitation and vegetations on mitral valve area. He became stuporous on the fourth hospital day and the brain MRI showed acute cerebral infarction. He was treated with penicillin intravenously for six weeks, which successfully controlled clinical features of infections. To our knowledge, this is the first case of P. multocida endocarditis complicated with cerebral infarction in Korea.

The distance education was designed in this paper consists of bulletin board, subject information, lecturing schedule, online instructions, questions and answers, submit and confirmation of reports, evaluation of lecturing, reference sites, chatting and discussion room, and data bank. The distance education coupled by WWW and database will change the educational form from one-direction to bi-direction between a teacher and the students. This can also provide a multimedia information to the students through WWW environment with convenient user interface. Those benefits made it possible to offer animated audio-visual materials and search for the information concerned through a hypertext technique. Besides, various kinds of informations were stored at database to increase an effectiveness in managing data. Since both teacher and students, are easy to add new information using the process of instruction to the database, the amount of the stored information in the distance education can be expanded effectively.

1996-1997년 겨울철에 유행한 인플루엔자의 임상역학적 분석 및 원인 바이러스의 분리

김수정,정규영,이용화,기창석,이남용,이상일,김지희 대한감염학회 1997 감염 Vol.29 No.4

목적: 인플루엔자는 매년 겨울 전 세계적인 유행을 일으키는 급성 호흡기 질환으로 높은 이환률과 사망율을 보인다. 국내에서도 1996-1997년 겨울철에 다수의 보고가 있었으나 아직 체계적인 감시가 이루어지고 있지 못하다. 저자들은 이 기간 동안 인플루엔자 바이러스 감염의 역학적 특성과 임상상을 연구하여 인플루엔자 감시의 기초 자료를 제공하고자 하였다. 방법: 1996년 10월부터 1997년 4월까지 삼성서울병원 임상병리과에 인플루엔자 바이러스 배양 검사가 의뢰된 모든 검체를 대상으로 인플루엔자 바이러스의 분리율과 유행 양상, 그리고 환자들의 임상상을 후향적으로 조사, 분석하였다. 결과: 총 461명의 환자로부터 525례의 검체가 의뢰되어 총 98명의 환자로부터 인플루엔자 바이러스가 분리되었다. 인플루엔자 A형은 54명의 소아 환자와 4명의 소아 환자로부터 분리되었다. 아형과 항원 특성 검사를 시행한 31례의 인플루엔자 A형 중 한 예에서 A/Wuhan/359/95 유사주로 확인되었고 12례의 인플루엔자 B형 중 5례에서 B/Guangdong/8/97 유사주로 확인되었다. 인플루엔자의 유행 양상은 3월과 4월 중순, 두 번의 인플루엔자 최고 분리 시점이 관찰되었고, 가장 많은 불리 빈도를 보인 연령층은 인플루엔자 A형의 경우 1세 미만이었고 인플루엔자 B형의 경우 3-5세였으며 폐렴이 가장 흔한 호흡기 질환이었다. 결론: 저자들은 3차 의료기관에서 분리된 인플루엔자 바이러스에 대한 역학적, 임상적 특성을 연구하였다. 지역사회에 대한 광범위한 연구가 아니므로 국내의 전반적 상황과는 차이가 있을 것으로 생각되지만 우리나라에서도 인플루엔자 바이러스의 이환률이 낮지 않을 것으로 생각되며, 보다 조직적이고 전국적인 인플루엔자 감시가 이루어져야 할 것으로 사료된다. Background: Although influenza has been a leading cause of global morbidity and mortality, we have few data regarding the epidemioloical and clinical characteristics of influenza activity in korea. Since an outbreak of influenza was recognized during winter of 1996-1997, we analysed the epidemiological and clinical features of influenza activity in the hospital seeting. Methods: All clinical specimens requested for isolation of influenza virus at Samsung Medical Center from October 1996 to April 1997 were included. Mardin-Darby canine kidney (MDCK) cell line was used for virus culture. Isolated viruses were confirmed with immunostain followed by subtyping. The demograpic and clinical characteristics of the patients were reviewed retrospectively. Results: Ninety eight influenza viruses were isolatd from 461 patients (21.3%). Influenza A and B virus were isolated from 58 (54 children and 4 adults) and 40 pediatric patients, respectively. One of 31 influenza A viruses was confirmed as A/Wuhan/359/95-like strain and 5 of 12 influenza B viruses were confiremd as B/Guangdong/8/97-like strains. Two distinctive peaks of influenza activity were recognized and the most common age of patients was less than 1 year for influenza A, and 3 to 5 years for influenza B. Common lower respiratory infections were pneumonia followed by croup, bronchiolitis and laryngitis. Conclusion: We analyzed the epidemiological and clinical features of influenza activity during winter of 1996-1997. Although this study was performed not in the community but in the hospital setting, the morbidity caused by influenza may not be low in Korea. Therefore, nationwide surveillance for influenza activity is warranted.

일차연접부위에서 악안면 영역에서 유래하는 유해자극의 전달 및 처리기전을 이해하고자 horseradish pe개xidase를 치수지배 구심성 신경섬유를 표식한 후 연수후각에서 미세구조 및 연절 양상을 분석하여 다음과 같은 결과를 얻었다. 표식종말은 소수의 큰 치밀소포가 관찰되는 종말 (S형) 및 다수의 치밀소포를 함유하는 종말 (LDCV형)등 2종류로 분류할 수 있었다. S형 및 LDCV형 표식종말의 연접양식은 유사하였으며, 다수의 표식종말이 1개 혹은 2개의 neurofile과 연접을 이루어 대단히 단순한 연접양상을 보였다. 표식종말은 가지돌기체 보다는 다수의 가지돌기가시와 연접을 이루는 빈도가 높았다. 표식종말이 세포체 및 이에 인접한 근심부 가지돌기와 연접하는 경우는 드물었으며, 소수의 표식종말에서 p-ending과 연접하는 경우를 보였다. 표식종말의 체적, 표면적, 사립체의 체적, neurofile과 접하는 면적, 활성부위의 면적, 단위표식종말당 연접소포의 수 및 연접소포의 밀도등은 넓은 범위의 계측치를 나타내었으며, 이는 5명 및 LDCV형 표식종말 사이에 유의한 차이가 없었다. 이상의 결과로 미루어보아 연수후각에서 치수유래 구심성 신경섬유 종말의 연접양식은 고유의 특징을 보이며 이는 신경회로의 기능과 밀접한 상관관계를 가지는 것으로 판단되었다. Little is known about processing mechanism of pain sensation of the oral cavity at the 1st synapse of trigeminal sensory nuclei. Serial ultrathin sections of tooth pulp afferent terminals, identified by the transganglionic transport of 1% wheatgerm agglutinin conjugated horseradish peroxidase, were investigated wih electron microscope. Quantitative ultrastructural analysis was performed on digitizing tablet connected to Macintoshi personal computer (software: NIH Image 1.60, NIH, Bethesda, MD). Labeled boutons could be classified into two types by the shapes of containing vesicles : S bouton which contained mainly spherical vesicles (Dia. 45-55 nm) and few large dense cored vesicles (Dia. 80-120nm), and LDCV bouton, which contained spherical vesicles as well as large number of large dense coredd vesicles. Most of the parameters on the ultrastruotural characteristic and synaptic organization of labeled boutons were similar between S and LDCV boutons, except shapes of containing vesicles. Majority of the labeled boutons showed simple synaptic arrangement. The labeled bouton were frequency presynaptic to dendritic spine, and to a lesser extent, dendritic shaft. They rarely synapsed with soma and adjacent proximal dendrite. A small proportion of labeled boutons made synaptic contacts with presynaptic pleomorphic vesicless containing endings and synaptic triad. Morphometric parameters of labeled boutons including volume and surface area, total apposed area, mitochondrial volume, active zone area, vesicle number and density showed wide variation and theme were not significantly different between S and LDCV boutons. The present study revealed characteristic features on ultrastructure and synaptic connection of pulpal afferents which may involved in transmission of oral pain sensation.

It has been hypothesized that jobs that have both high psychological demands and low decision latitude("job strain") can lead to musculoskeletal disorder. The objective of this study was to test whether job strain was correlated with the presence of work-related musculoskeletal disorder, especially myofascial pain syndrome(MPS). Information on demographic factors, confounders such as household load and taking care of children or not, and scores for decision latitude, job demand, and social support was obtained by self-administered questionnaire, which had been developed in Korean language, by adopting NIOSH instrument and Extended Karasek Model(16 items). All subjects were also examined by rehabilitation medicine specialists for musculoskeletal disorders. Subjects(n=370) could be categorized into 4 groups, these were, housewives(n=89), shipyard CAD workers(n=89), general female workers(n=79; nurses, insurance counselors, public officials, clerks, etc), and telephone directory assistance operators(n=113). Results from univariate analyses indicated that all demographic factors, all confounders, scores for decision latitude and social support were not associated with the risk of musculoskeletal disorder. However, score for job demand was higher in musculoskeletal disorder cases than others. In subgroup analysis, this association was convinced again, in telephone directory assistance operators. Job strain model showed that the group of telephone directory assistance operators was high-stain group, and OR of musculo skeletal disorder was 2.446(95% C. I. : 1.174, 5.096), when comparing this with the low strain group. In conclusion, job strain is a risk factor for work-related musculoskeletal disorder.

Studied in this paper is how multiple quantum coherence develops in the anisotropic distribution of dipolar couplings. The magnitude of dipolar couplings was varied with oriented angles. The larger dipolar coupling was, the bigger frequency of multiple quantum coherence was. The multiple quantum coherence is decided with proportion of the magnitude of dipolar couplings. The theory equation for multiple quantum coherence and the magic angle 54.7˚in the solid NMR spectroscopy was verified in our research. The excitation pattern of n-Quantum coherence, which can induce the effective size to characterize spin system, is expected in larger and more complicated spin system for understanding the relation of dipolar coupling and multiple quantum coherence.
