N/A We obserbed 24 cases of tsutsugamushi disease occur- ring in the Gang-Won-Do area from September to October 1988, which were confirmed by indirect immunofluorescent antibody test, and analysed their clinical findings. On physical examination eschars which can be a clinical clue to tsutsugamushi disease in the early stage of infection were recorded in 11 cases (45%). Common laboratory features included thrombocytopenia in 19 cases (95/o), and increased SGOT in 22 cases (92%), SGPT in 49 cases (79%), LDH in 19 out of 20 cases (95%) tested, CK in 7 out of 20 cases (35%) tested and serum ADA level in 12 of 13 cases (92%) tested. Serum fibrinogen was decreased in 5 of 13 cases (38%) tested, FDP was positive in 8 of 13 cases (62%) tested and prolonged prothrombin time was observed in 9 cases (38%). When IgM and IgG titers were measured separately, two distinct responses were seen. The IgM titers gradually declined during the period from 14-40 days. The IgG responses in the same patients developed more slowly. In our study, tsutsugamushi disease was a mild to severe febrile illness of 1 to 2 weeks duration. We think that more concern about tsutsugamushi disease is necessary because of possible mortality in poorly treated cases as well as a need for more precise differential diagnosis of acute febrile illness.

『燕轅直指」硏究

전일우 崇實語文學會 2003 崇實語文 Vol.19 No.-

본 논문은 19세기 〈연행록〉(燕行錄)을 대표하는 「연원직지」 연행기록의 문학적 가치에 대한 연구이다. 이 글의 저자 김경선은 기존 〈연행록〉의 장점들을 선별하여 종합형식으로 구성하였다. 즉 「연원직지」는 동지사(冬至使)겸 사은사(謝恩使)인 정사 서경보(正使徐耕輔)ㆍ부사 윤치겸(副使尹致謙)의 서장관(書狀官)으로 순조(純祖) 12년인 1832년 10월 20일에 한성을 출발하여 1833년 4월 2일에 돌아오기까지의 연행기록이다. 〈연행록〉은 한ㆍ중간을 여행하는 과정에서 기록한 여행기에 속한다. 즉 여정(旅程)에서 나타나고 보여지는 것으로 간과할 수 없는 것들에 대해 자신의 감상과 중요한 사건ㆍ사실을 기록한 글이다. 특히 〈연행록〉은 조선의 대외적 역사에 있어서 중요하게 자리한다. 즉 본고에서 연구하는 「연원직지」 또한 사행기록에 있어서 비중 있는 문학적 자료로 위치를 점하고 있다. 이 글의 저자 김경선은 기존 〈연행록〉가운데 가장 뛰어나다고 한 삼가(三家) 연행록의 장점들을 중심으로 「연원직지」를 기록했다. 이는 과거의 많은 사행기록과 역사적 전거를 모두 수렴해서 일목요연하게 정리ㆍ기술한 사행의 집대성적인 기록이다. 나아가 단순한 고증에 그치는 것이 아닌, 객관적 시선의 견지에서 '이용후생'의 새로운 의식까지 확인하게 한다. 한편 겉으로 드러내지 않은 저자의 서술의도에서 다소 내용의 지루함을 보이기도 한다. 이는 등록을 해야하는 서장관의 위치와, 전통적 노론의 한계성으로 나타난다. 그러나 「연원직지」에서 김경선이 의도했던 '집대성적' 가치와 '이용후생'의 확대로 충분하게 확인이 된다. 앞으로 다른 연행록과 비교 연구를 통한 문학적 가치에 대한 연구가 이루어져야 할 것이다.

This study provided an analytical method for real-time system identification by utilizing fundamental linear algebra and minimizing a quadratic form of the differences in physical properties calculated from the initially given properties and the next expected properties. The validity of the proposed method depends on the selected weighting matrix. Although it was observed that the proposed method gives reasonable values by the proper selection of the weighting matrix, the deficiency of this method like the proper selection of weighting matrix with time needs to be improved.

A study on the effectiveness and convergency of damage measures for structural damage detection using the nonlinear parametric projection filter algorithm is presented in this paper. Damage measures are associated with the change in mode shape and displacement due to structural damage. So, five damage measures are presented in this paper. They are static displacement, curvature of static displacement, natural frequency, mode shape and curvature of mode shape. The static data are obtained by loading static load to the structure. And modal and dynamic data of a vibrating structure can be gained without dismantling the structure, these data are very useful in various aspects. But the results of detection are affected by the kind of damage measures to be used. The effectiveness and convergency of these damage measures on the structural damage detection using the nonlinear parametric projection filtering algorithm are demonstrated with the numerical examples.

The purposes of this study are to analyze the emotional state of participants in football-lovers' society and the degree of their satisfaction with leisure, emphasize the influence of participation in sports on mental emotional condition and the necessity of football as a leisure sport and recognize the importance of sports to the people with 212 adult subjects who participate in football-lovers' society. For the above purposes of this study, it conducts one-way ANOVA and Canonical Correlation Analysis using statistical program SPSS 10.0 and the results of this study are as follows. First, as the participants in football-lovers' society are younger, they feel less anger and fatigue in their daily life, but as they are older, they fee much more strengthened physical and educational satisfaction. Second, the higher educational level is, the higher social satisfaction is. Third, as the participants in the society earn higher monthly income, they have higher satisfaction with their leisure. Fourth, in anger, confusion and fatigue, as they have longer duration of participation in football-lovers' society, they have more stable emotional condition and in physical and social satisfaction, they have higher physical and social satisfaction less than two-year experience of leisure activity and higher mental and educational satisfaction over three-year experiences of their activities in the society. According to frequency a month, confusion is most serious in less than once a month and their satisfaction with leisure is improved through the relaxation of tension and as they have higher mental satisfaction, their emotinal state is stabilized most.

Objectives: To find work related factors affecting perceived fatigue among male metal product assemblers. Methods: The study subjects were metal product assemblers from three metal product companies (476 car parts assemblers, 610 car engine assemblers, 454 ship engine assemblers). From the total of 1,540 subjects, 1,136 (73.8%) were included and 38 respondents with insufficient replies were excluded. Associations between fatigue score and other variables (general characteristics, job related factors, workload, job stresses) were investigated in terms of the concept of multidimensional fatigue construct by self administered questionnaire. Using MFS (Multidimensional Fatigue Scale), JCQ (Job Content Questionnaire), and Borg's scale, we estimated the fatigue, job stress, and workload, respectively. Fatigue score was estimated by 'sum of fatigue' in MFS. Associations were tested by linear regression analysis using SAS v.8.0. Results: In this study, the fatigue related factors were older age, longer working hours per week, higher workload, higher job demand, lower decision latitude, and lower supervisor support. Conclusions: Prolonged working hours, higher workload, higher job demand, poor supervisor support and lower decision latitude were fatigue related factors among the male metal product assemblers of this study.

Space truss structures are composed of many members, so it is difficult to find damaged members from the whole system. Therefore, damage detection takes use of 2-step damage identification method. First, kinetic energy change ratio is used to find damage region including damaged members, and then extended parametric projection filter algorithm is used to detect damaged members in damage region. The results of 2-step damage identification method that apply to examples are next. First, in the case of finding damage region using kinetic energy change ratio, the ratios of nodes including damage members are large, so we can consider as this measure is effective. Next, in the case of finding damaged members at nodes of damage regions using extended parametric projection filter algorithm, the stiffness ratios of damaged members converge exactly.
