        한국의학사 강의 개발과 강의 사례 연구

        이현숙 ( Hyun Sook Lee ) 연세대학교 의과대학 의사학과 의학사연구소 2013 연세의사학 Vol.16 No.1

        This research will explore how to develop and teach Korean medical history in Korean universities. In 2009-2010, I participated in a project called “Developing the Module of the Korean Medical History,” which was funded by the Korean Research Foundation. For this project, done at Yonsei Medical College, five specialists worked together to develop the module: Yeo In-sok (Director of the project, Contemporary period), Lee Hyun-sook (Ancient period and the Goryeo dynasty), Kim Seong-su (Joseon dynasty), Sihn Kyu-whan (Modern 1: the late 19th century and early 20th century), and Park Yun-jaeoe (Colonial period). One of the results of this project was the publication of the book History of Medicine in Korea. As a case study, I analyzed the results of my experiences teaching Korean medical history to graduate students in medical college in 2010 and freshmen in nursing college in 2013. In the graduated school of medical college, all of the five members gave lectures, however, it seems like too many lecturers for five students in eight classes. I could not give any previous reading material and assignment. It means we need more time to teach properly. In 2013, I taught Korean medical history by myself as the Korean History class in a nursing college. I invited Prof. Kim and Sihn as a guest teacher. According to my survey of the nursing college`s freshmen students, my students selected the forensic medicine of the Joseon dynasty and the military medicine of Silla Unification War in the 7th Century as the best subjects. The next favorite subjects were the comparison of the Modernization and Exploitation theories in colonial Korea, as well as Ancient Medicine, specifically trephination and skull modification. They selected these because the visual media, made by KBS, about the forensic medicine of the Joseon dynasty and about the artificial cranial deformation of the Gaya, which we had watched in the class. From this, I discovered that watching visual images was the most efficient method of learning for the class. Another assignment I gave to my classes concerned the military medicine of ancient Korea, and my students were responsible for reading my article “Military Medicine of the Silla Unification War,” summarizing the article, and recording their thoughts and impressions. This subject was also a favorite. I determined that self-study was a very efficient way to develop students` ideas and passions. The results of the survey about the comparison of the Modernization and Exploitation theories revealed that my students supported the Exploitation theory more than the Modernization theory. In the 1st class, 17 students supported the Modernization theory, while 49 students subscribed to the Exploitation theory in the Colonial medicine. On the other hand, only 7 students agreed with the Modernization theory at the 2nd class, while 55 students supported the Exploitation theory. I believe this is the result of the influence of Prof. Sihn, who had provided a special lecture to my students as a supporter of the Exploitation theory. I also recognized that my way of questioning had influenced the answers of the students. In the question of the 1st class, I had explained the Modernization theory at first, and then I had them choose “agree” or “disagree” and explain their answer. In the 2nd class, on the contrary, I introduced the Exploitation theory in advance and had them select “agree” or “disagree.” The 2nd class might have been influenced by the method of questioning, and they selected the Exploitation theory as an easier answer. Most of the nursing college`s students were content learning about the history of Korean medicine as a Korean history class. The text book History of Medicine in Korea played a considerable role in guiding my students, even though it has many weaknesses. In conclusion, the history of Korean medicine is a good subject for teaching Korean history at a university, and it also develops the identification of medical college students.

      • 배우 역할 구축에서의 상상력의 적용 - 리 스트라스버그의‘즉흥’을 활용한 <타클라마칸> 의 김현숙 역을 중심으로

        김현숙 ( Kim Hyun-sook ) 한양대학교 공연예술연구소 2016 공연예술연구 Vol.3 No.-

        본고는 배우의 역할구축 과정에서 예술적 상상력의 구체적 적용사례에 대해 논하고자 한다. 연구의 목적은 배우가 상상력이라는 개념들을 어떻게 이해하고 이를 토대로 실제 마주한 상황들에 어떻게 적용하고 대처해 나가는지 정리하고 논하는 데 있다. 스타니슬랍스키, 스텔라 애들러, 리 스트라스버그, 미카엘 체홉 등 유수한 액팅코치들이 강조했듯이 상상력은 배우의 연기에서 가장 중요한 핵심 개념으로 이야기 되어왔다. 특히, 배우의 예술적 상상력은 역할의 구체화 작업에 좋은 요소가 된다. 따라서, 본고는 예술적 상상력의 개념과 방법론의 이해와 함께 본 연구자가 직접 참여한 작품 <타클라마칸> 을 통해 구체적인 방법을 논하고자 한다. 적용과정에서 이 장면을 선택한 이유는 극중 인물의 현실과 상상 사이에서 빚어지는 갈등이 잘 표현되어야 하는 만큼 배우에게 상상력이 많이 요구되었기 때문이다. 또한 역할구축에 있어 배우의 감정이나 감각을 열어주는데 적합하다고 생각했다. 먼저 그 방법론의 예로써, 리 스트라스버그(Lee Strasberg, 1901-1982)의‘즉흥’을 활용하고자 한다. 리 스트라스버그의‘즉흥’을 중점적으로 살펴보는 이유는‘나’로부터 출발하는 내부적 접근과 텍스트의 외적요소를 통해 내적세계로 접근하는 외부적 접근까지 모두 적용해 볼수 있기 때문이다. 연구의 전개는 먼저 역할구축을 위한 배우의 예술적 상상력에 대해 이해하고 리 스트라스 버그의 방법론‘즉흥’(Improvisation) 안에 정서와 기억훈련 기초단계 중 하나인‘개인사물에 대한 기억’훈련을 살펴본다. 마지막으로 <타클라마칸>의 구체적 사례를 통해 배우의 상상력을 통한 역할구축의 실제적 활용에 대한 올바른 방안을 제시하고자 한다. This study is about the specific application of imagination in the actor’s process of creating a role. The purpose of this study is to discuss how actors understand the concept of imagination and how they apply this concept to the situations of their acting. The famous acting coaches Constantine Stanislavsky, Stella Adler, Lee Strasberg, and Michael Chekov all emphasize that imagination is the most important skill in acting. It is through the actor’s imagination that a role can materialize and be created. Therefore, this study will analyze and discuss the specific method, through the concept and methodology of imagination, that the researcher used in her role in the play < Taklamakan >. The reason for choosing the scenes of this play is because the actor needs a lot of imagination to appear conflicted between the reality and imagination of the character. Also, it is appropriate to expand one’s emotions and feelings when creating this role. Lee’s Strasberg’s ‘Method’ acting technique of improvisation was used. Through Strasberg’s improvisation technique, the actor was able to apply an inner approach, ‘I,’ and an external approach through elements of the text. This study is developed to understand the use of imagination in creating a role through ‘personal memories of things’ which is a foundation of Emotion and Memory in Lee Strasberg’s improvisation technique. Finally, this research suggests the proper and practical utilization in creating a role through imagination in the play < Taklamakan >.

        간호실무에서 신봉이론(Espoused theories)에 대한 탐색적 연구

        서문자,김혜숙,이은희,박영숙,조경숙,강현숙,임난영,김주현,이소우,조복희,이명하,지성애,하양숙,손영희,권성복,김희진,추진아 성인간호학회 2001 성인간호학회지 Vol.13 No.1

        As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

        폐렴구균 감염증에서 항생제 내성의 임상적 의미 : Asian Network for Surveillance of Resistant Pathogens(ANSORP) Study

        정숙인,기현균,손준성,고관수,김나영,장현하,오원섭,백경란,이남용,김신우,이혁,--,송재훈 대한감염학회 2003 감염과 화학요법 Vol.35 No.5

        목적 : 전 세계적으로 폐렴구균의 페니실린을 포함한 β-lactam과 마크로라이드 및 퀴놀론 계열의 항생제에 대한 내성이 급격히 증가하여 임상적으로 문제가 되고 있으나, 시험관내 내성이 실제 임상적 예후에 미치는 영향에 대해서는 아직까지 논란이 되고 있다. 본 연구는 폐렴구균의 항생제 내성률이 높은 아시아 지역에서 항생제 내성이 폐렴구균 감염증의 임상경과에 미치는 영향을 평가하기 위하여 시행되었다. 방법 : ANSORP에서 주관한 전향적 임상 연구로서 1999년 11월부터 2001년 8월까지 아시아 지역 11개국의 14개 기관에서 진단된 침습성 폐럼구균 감염증 환자를 대상으로 내성 균주 감염의 위험요인, 임상양상, 예후 등의 임상적 분석을 시행하였다. 결과 : 총 646명 환자의 평균연령은 30.1세(6일-89세)였고, 이전 3개월 내에 항생제 사용력이 있는 환자는 159명(32.4%)이었다. 질환별로는 폐렴이 377예(58.4%)로 가장 많았고, 중이염 67예, 뇌수막염 66예(10.2%), 일차성 균혈증 65예(10.1%)였다. 총 646균주 중 347균주(53.7%)가 페니실린 비감수성(중등도 내성 23.1%, 고도 내성 23.1%)이었고, 페니실린에 대한 MIC_(90)은 0.03㎍/mL에서 4㎍/mL까지의 분포를 보였다. 페니실린 비감수성 균주에 의한 감염증과 차이가 없었다. 페니실린 내성 폐렴구균 폐렴에 의한 사망률은 페니실린 감수성 폐렴구균 폐렴에 의한 사망률과 차이가 없었다(p=0.846). Erythromycin에 대한 고도 내성을 보이는 균주의 비율이 매우 높았으나, 실제 임상상이나 치사율에는 영향을 미치지 않았다(p=0.092). 페니실린 비감수성 폐렴구균에 의한 뇌수막염의 치사률도 감수성 균주에 의한 사망률과 차이가 없었다(p=0.059). 결론 : 본 연구의 결과 페니실린 및 베타 락탐 제제에 대한 시험관 내성은 폐렴구균 폐렴이나 뇌수막염의 임상상이나 치사율에 영향을 미치지 않는 것으로 확인되었다. 이는 내성의 정도와 연관될 것으로 생각되므로, 향후 고도 내성 균주가 증가할 때 추가 검증을 요한다. 아울러 macrolide 및 퀴놀론계 항생제 내성의 임상적 의미에 대한 후속 연구가 필요할 것으로 사료된다. Background : Despite the widespread emergence of antimicrobial resistance among pneumococcal strains worldwide, clinical implications of in vitro resistance still remain an open question. To evaluate the clinical impact of pneumococcal resistance in Asian countries where the prevalence of pneumococcal resistance was reported to be highest in the world, ANSORP has performed a prospective, multinational surveillance study with cases with invasive pneumococcal diseases in Asian countries. Methods : In vitro susceptibility of pneumococcal isolates was determined by broth microdilution tests with 16 antimicrobial agents. All enrolled cases of pneumococcal infections were analyzed with regard to demographic data, clinical features, risk factors and mortality. Results : A total of 646 patients with pneumococcal infections were enrolled from 14 centers in 12 countries between the period from November 1999 to August 2001. Pneumonia (58.4%) was the most common clinical disease followed by bacteremia (33.4%), otitis media (10.4%), and meningitis (10.2%). Among 646 isolates, 347 (53.7%) were penicillin non-susceptible (intermediate 23.1%, resistant 30.7%). MIG_(90)s for penicillin ranged from 0.03 (India) to 4.0 ㎍/mL (Korea, Taiwan, Vietnam, and Hong Kong). Overall mortality from pneumococcal diseases by penicillin non-susceptible strains was not different from that by susceptible strains. Pneumococcal pneumonia caused by penicillin- or erythromycin-resistant strains showed similar mortality, severity of illness, or complications to that by susceptible strains. Mortality from pneumococcal meningitis caused by penicillin non-susceptible strains was also similar to that by susceptible strains. Conclusion : Data suggest that current situation of in vitro resistance to penicillin or macrolides may not affect the mortality from pneumococal pneumonia or meningitis caused by antibiotic-resistant strains.

        발열을 동반한 호중구감소증에서 Cefepime 단독투여와 Ceftazidime 및 Tobramycin 병합투여의 효능비교

        정현욱,채제욱,강미라,양정채,문치숙,기현균,장현하,오원섭,김기현,백경란,이남용,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

        목적 : 국내에서 발열을 동반한 호중구감소증이 있는 악성 종양환자에게 경험적 항생제로 베타락탐계 항생제와 아미노배당체의 병합요법의 사용이 일반적이다. Cefepime은 광범위 항균 작용을 가지고 있어, 그람 음성균 뿐만 아니라 그람 양성균에 대해서도 우수한 효과를 나타낸다. 재료 및 방법: 발열을 동반한 호중구감소증이 있는 악성 종양환자를 대상으로 무작위, 공개, 비교 연구를 시행하였다. 대상 환자를 무작위로 cefepime 단독요법군과 ceftazidime 및 tobramycin 병합요법군으로 나누어 투여하고 각각의 임상적 효능과 안전성을 비교하였다. 구강및 인후 점막염이 있는 환자에서 분리된 녹색 연쇄알 구균에 대한 항생제 내성 정도를 조사하였다. 결과 : 대상환자 89명 중 CA 투여군이 48예(53.9%), CT 투여군이 41예(46.1%)이었다. 발열의 유형별로 MDI는 18예(20.2%), CDI는 9예(10.1%), UF는 62예(69.7%)로 두 군 간에 차이가 없었다. CA 투여군과 CT 투여군의 임상적 호전률은 시험약 투여 후 2-4일째 각각 91.7%, 85.4% (P=0.31), 치료 종료 시 각각 91.7%, 100% (P=0.15)로 두 군간에 유의한 차이가 없었다. 치료 종료 시 CA 투여군과 CT 투여군의 세균학적 소실률은 모두 100%로 두 군간의 유의한 차이가 없었다(P=0.78). 점막염이 있는 환자로부터 녹색 연쇄알 구균이 분리된 경우는 25예(28.1%)이었으며, 분리된 녹색 연쇄알 구균은 penicillin, ceftriaxone, cefepime, vancomycin에 모두 감수성을 보였다. 약제 관련 이상 반응의 발생 빈도도 두 군간에 유의한 차이가 없었다. 결론 : 발열을 동반한 호중구감소증이 있는 악성 종양환자의 경험적 항생제로서 cefepime 단독요법은 ceftazidime 및 아미노배당체의 병합요법만큼 효과적이고 안전하였다. Background : Broad-spectrum antibiotic therapy has been recommended as an empirical regimen in cancer patients with febrile neutropenia. Cefepime is a fourth generation cephalosporin with good activity against both gram-positive cocci and gram-negative bacilli. Materials and Methods : To compare the efficacy and safety of cefepime alone with ceftazidime plus tobramycin as empirical regimen for adult cancer patients with febrile neutropenia, a randomized, open label, comparative trial was performed. If the patient showed clinical improvent 72 hours, antibiotic could be changed to oral ciprofloxacin. Clinical and microbiological responses were determined at 72 hours and at the end of therapy. To investigate the antimicrobial resistance of viridans streptococci, swab cultures were obtained from throat in all enrolled patients and antimicrobial susceptibility tests were performed by using microdilution method according to the NCCLS. Results : A total of 89 patients were enrolled. Forty-eight patients received cefepime alone (CA), and 41 patients received ceftazidime plus tobramycin (CT). Demographic and baseline clinical characteristics were similar in both groups (P>0.05). The initial clinical success rate at day 2-4 in group CA (91.7%) was similar with that in CT group (85.4%) (P=0.31). At the end of therapy, the final clinical success rate in CA group (91.7%) was similar to that in CT group (100%) (P=0.15). In 18 patients, with microbiologically defined infections, the eradication rate was 100% in both groups. Adverse events including liver dysfunction (21.3%) and renal dysfunction (2.2%), were similar in both groups (P=0.87). Viridans streptococci were isolated from the throat cultures in 25 cases, and all of these strains were susceptible to penicillin (MIC_(90) 0.12 ㎍/mL), cefepime (1 ㎍/mL), and vancomycin (0.12 ㎍/mL). Conclusion : Efficacy and safety of cefepime monotherapy was comparable to the combination of ceftazidime and tobramycin. It could be used as an alternative empirical regimen for treating cancer patients with febrile neutropenia.

        The survey study was conducted to investigate the rice cake consumption pattern including the frequency of intake and the degree of preference and the area of improvement for Korean rice cake among college students. About the motive for purchases of rice cake, 'taste is good(43.3%)' was the highest, and 'eat as a snack' the next (42.9%). The reason which does not eat the rice cake frequently was uncomfortable to eat (24.1%), insipid(21.4%), not variously assorted(17.9%) in the order named. The college students surveyed were eating rice cake as a snack mainly. They wanted the rice cake to be charmed and be in pretty shape, and fusion style for gift. And they wanted to be rice cake more sweetened and cool taste like ice cream. Therefore, traditional rice cake is required for further research for the development of product which is more acceptable for the young adults.

        This study examined the writing methods of Lee Sang, who is representative of modernism in the 1930s, and how his methods have been adopted by writers such as Hwang Sun-Won, Kim Seung-Ok and Choi In-Ho; Particularly, this study found that the writing methods seen in Lee Sang’s writing such as juxtaposition of the accelerator effect and contrast using repetition and climax, poetic ellipsis and a modernist sensibility, induction of numbers and deconstruction, directly and indirectly influenced Hwang Sun-Won, Kim Seung-Ok and Choi In-Ho based on a comparative analysis on their writings. Lee Sang and Hwang Sun-Won were members of a coterie who wrote for magazines including 『Samsa Literature』 and ≪Tokyo Student Art Group≫ which continued the modernist tradition. Considering the time they spent in Tokyo and their acquaintance with artist Jeong Hyun-Woong, this study has examined the direct and indirect effect of Lee Sang’s writing on Hwang Sun-Won’s writing through a comparative analysis of their writings and their similarities. Kim Seung-Ok, one of the leading writers of the 1960s, also adopted Lee Sang’s writing techniques by examining aspects of the public or social realm that had become disconnected and excluded in the process of modernization and rapid urbanization through devices such as story fragmentation, repetition of silence and severance, poetic ellipsis and by invoking a modernist sensibility. In this study, it was confirmed that Choi In-Ho, who restarted his literary career with 『Modern Literature』 upon the recommendation of Hwang Sun-Won, was also affected by Lee Sang’s writing as he described big city life and the irrational and unreasonable aspects of modern life through a modernist sensibility, wit, humor and illusion. That is, Lee Sang’s writing - which represents modernism in the 1930s - directly and indirectly influenced Hwang Sun-Won who was the member of a coterie who wrote for 『Samsa Literature』 and ≪Tokyo Student Art Group≫ and considerable elements of their writing were rhetorically adopted and expanded by Kim Seung-Ok and Choi In-Ho.

        The study was to investigate the functional properties of soy protein isolate hydrolyzed by immobilized α-chymotrypsin and the quality characteristics of soy ice cream made by the soy protein isolate treated with immobilized α-chymotrypsin. Up to the hydrolysis rate of 22.9%, treatement by immobilized α-chymotrypsin costed more time than that of α-chymotrypsin. Foam and emulsion capacity were decreased by the number of repetitive usage. Apparent viscosity and overrun of soy ice cream treated with immobilized α-chymotrypsin and α-chymotrypsin were shown similar tendency. In the sensory characteristics, soy ice cream by enzyme treatment was evaluated as much acceptable than untreacted soy ice cream in the item of beany flavor, icy feel and overall quality. For efficient use of immobilized α-chymotrypsin industrially, α-chymotrypsin immobilized on glass beads can be reused for about 11 times more than α-chymotrypsin.
