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

권오용,윤희주,한수자 충남대학교 자연과학연구소 1987 忠南科學硏究誌 Vol.14 No.2

This study demonstrates the effects of four detergents and three on the activity change of phospholipase C which is prepared from the cultural broth of Bacillus cereus. This assay of phospholipase C activity was carried out with phosphatidylcholine micelles which were mixed with the detergents and sterols, with increase a molar ratio of these compounds to phosphatidylcholine. Phospholipase C was highly activated at 0.5 molar ratio of Tween 80-mixed micelles. In the case of Triton X-100, it was activated at higher molar ratio indicated 1.0. Sodium dodecyl sulfate was more effective than that of the other detergents at lower molar ratio. However sodium deoxycholate-mixed micelles increased the activity more 7 times than that of the control group. This maximum activation was occurred at 2.5 molar ratio and the turbidity was gradually decreased. Cholesterol and ergosterol increased the activity until molar ratio reached up to 0.9. But the activity was higher at 0.3 molar ratio for stigmasterol. Consequently, it was indicated that phospholipase C was activated with the supplement of detergents until the mixed micelles made a number of small and spherical shape.

Background and Objectives: With increasing age of population, stroke and dementia become greater health problems in Korea. However, there have been no studies on poststroke dementia in Korea. We intended to elucidate the frequency and clinical correlates of poststroke dementia in a hospital-based cohort. Methods: From July 2001 to July 2002, 372 patients were hospitalized to Eulji General Hospital within 7 days from onset with acute stroke or transient ischemic attack. Two hundred-eight patients (55.9%) were followed up and interviewed more than 1 year later (451 ±83.3 days). Dementia was diagnosed by Korean Dementia Screening Questionnaire (KDSQ) obtained by a direct interview. Based on Eulji Stroke Registry, demographic factors, risk factors for stroke, stroke characteristics, and stroke outcomes were gathered and examined. Results: Of 208 patients, poststroke dementia was detected in 36 patients (17.3%, 20 males, age=64.5±9.4 years). Poststroke dementia was associated with history of stroke, aphasia, modified Rankin Disability Scale (MRDS) at 3 month after stroke and when interviewed, and Barthel index at 6 months after stroke (p;0.05). Its correlation with diabetes mellitus and National Institute of Health Stroke Scale at discharge were marginally significant (0.05;p;0.1). Conclusions: Post-stroke dementia is common in Korean stroke patients. Its frequency is comparable to that in other countries. The correlates of poststroke dementia and their clinical meanings are demonstrated.

급성 백혈병 환자에서 감염증의 양상 및 예후인자에 관한 연구 : 1988년∼1995년까지

정희진,김병수,신상원,김열홍,김우주,김민자,김준석,박승철,김권범 대한감염학회 1998 감염 Vol.30 No.3

목적 : 급성 백혈병의 경우 골수기능이 억제되고 항암화학요법에 따른 골수기능 저하로 감염의 위험이 증가하며 감염의 치료가 환자의 생존에 큰 영향을 미치게 된다. 이에 저자들은 1988년부터 1995년까지 고대 구로병원에 급성 백혈병으로 입원했던 환자들 중 입원 기간 내 감염이 있었던 경우를 대상으로 하여 감염의 위험인자 및 감염증의 예후를 후향적으로 분석함으로써 향후 급성 백혈병환자의 감염의 치료에 대한 지침을 얻고자 하였다. 방법 : 급성 백혈병으로 확진된 환자들 중 감염병에 이환된 경우를 대상으로 하여 각각을 미생물학적 확인감염, 임상적 확인감염, 그리고 설명 불가열로 구분하였다. 각각의 경우에서 감염 당시의 호중구 수, 호중구 감소 기간, 항암화학요법과의 연관성, 감염 병소, 배양된 검체 및 원인균, 선택적 소화관 살균법의 사용여부 및 골수회복 여부 등을 조사한 후 환자의 예후와 어떤 관계가 있는 지 조사하였다. 결과 : 연구 대상은 총 113예로 남녀비는 46:67 이었고 평균연령은 34±13세, 진단은 급성 골수성 백혈병 (AML)이 84예, 급성 림프구성 백혈병(ALL)이 29예였으며, 감염시 평균 호중구수는 663±1678/㎣이었고, 호중구 감소 기간은 평균 18±13일이었다. 감염양상은 항암화학요법과 연관된 감염이 84예로 대부분이었고 미생물학적 확인 감염이 40예로서 35%였으며, 폐렴과 원발성 패혈증이 각각 20예와 19예로 가장 많았고, 카테터 연관 감염이 7예로 나타났다. 배양된 균주는 E. coli가 10예(25%)로서 가장 많았으며, 전체적으로 E. coli, P. aeruginosa, K. pneumoniae 등의 그람음성균이 63%로 대부분을 차지하였으나 최근 그람양성구군 및 진균의 분리율이 증가하는 양상을 보였다. 감염증의 예후를 분석한 결과 진균 감염인 경우나 호중구 감소 기간이 긴 경우 사망률이 높았으며 그 중에서도 골수 기능이 회복 여부가 환자들의 생존과 통계적으로 유의한 연관이 있었다.(P=0.01). 결론 : 급성 백혈병 환자들에서의 감염은 관해유도화학요법 후 초래되는 호중구 감소와 유의한 관계가 있으며, 폐렴 및 패혈증의 임상양상을 보이는 경우가 흔하고, 원인균별로는 그람 음성균이 주류를 이루나 최근 그람 양성균 감염이 증가하는 추세를 보였다. 감염의 예후 인자로는 진균 감염인 경우나 호중구 감소 기간이 긴 경우 사망률이 높았으나 골수 기능의 회복여부가 결정적인 역할을 하는 것으로 나타나, 향후 급성 백혈병 환자의 치료에 있어 감염 빈도의 감소와 감염에서의 조속한 회복을 위해서는 골수 기능의 회복에 중점을 두어야 할 것으로 사료된다. Background : Infection is one of the most important and fatal complications in patients with acute leukemia. The characteristics of infection in acute leukemic patients are different from those in other diseases by the lack of normal inflammatory responses or distinct clinical evidence except fever. To improve the outcome of acute leukemia, it is very important to recognize the risk factors, patterns and prognostic factors of acute leukemia. Methods : We analyzed retrospectively the patterns of infection from 113 febrile patients with acute leukemia from January, 1988 to December, 1995. To determine the prognostic factors and the outcome of infection, the following variables were analyzed: the presence of neutropenia, use of chemotherapeutic agents, type and site of infections, isolated organisms, gastrointestinal decontamination, duration of neutropenia, and bone marrow recovery. Results : Out of 113 febrile patients with acute leukemia, 84 infection episodes(74%) occurred after chemotherapy. The mean duration of neutropenia was 18±13 days. The incidence of microbiologically-documented infection(MDI) was 35%(40/113). Pneumonia was the most common infection(26%), followed by primary sepsis(24%), catheter-related infection(9%). In cases of MDI, 63% were caused by gram-negative bacteria, followed by gram-positive bacteria(28%), and fungi(10%). Escherichia coli(25%) was the most common isolated in MDI. Regarding the prognostic factors in cases with infections, the recovery of bone marrow function was the only statistically significant factor(P=0.01). Conclusion : Infection has been a major cause of morbidity and mortality in acute in acute leukemic patients. To prevent infection and thereby improve the prognosis of acute leukemia, restoration of bone marrow function at early stage is important.

과학교사의 양성을 위한 교육과정 또는 그 프로그램의 주된 목적은 바람직한 과학교사가 지녀야 할 전문적 자질을 함양시키는 데에 있다. 그러나 우리나라의 과학교사 양성을 위한 프로그램 또는 사범대학 과학교육학 계열 교육과정에는 과학교사 교육의 본성과 그의 자질에 관한 연구의 결과가 충분히 반영되어 있지 않다. 이 연구는 자질기반 과학교사 양성 교육과정의 개발 틀, 교직의 전문성과 전문성발달기준, 우리나라의 과학교사 양성 교육과정 및 프로그램에 관한 문헌을 조사·분석한 다음, 그 결과로부터 우리나라의 과학교사 양성을 위한 교육과정의 개발 방향을 도출하고 그 모형을 탐색할 목적에서 수행하였다. 이 연구에서는 과학교사 양성 교육과정을 그 과목이나 지식기반 영역에 따라 교수내용알기(PCKg), 교수구성단위(TPCs), 내용표상화(CoRe)와 교수전문경험자료(PaP-eRs), 그리고 교수상황지식(PCxK)을 단위로 이용하여 구성할 것을 강조하였다. 또한 과학교사의 전문적 자질의 함양에 목적을 둔 교육과정 또는 그 프로그램의 과학교육 및 과학과 관련된 과목으로 일반과학, 심화과학, 일반과학교육학(과학교육론, 과학 교수-학습 포함), 과학 교육과정 및 평가, 과학교육 시설과 자원, 과학교육 실습, 과학교육 연구를 제안하였다. The subjects and their contents comprising the curricula for secondary science teacher education should be selected/organized to assist pre-service teachers to gain understandings of knowledge ba ses and to help them acquire professional teaching competences. However, the nature of science teacher education has not been reflected on the Korean science teacher education programs. The research was performed to review the literature on teachers' competencies including PCK(pedagogical content knowledge), teaching as profession, curricula or programs for secondary science teacher education, and, based on the results, to suggest curricular subjects and their contents for secondary science teacher education in Korea. The research emphasizes that the subjects and their contents for secondary science teacher education should be developed by the use of PCKg(pedagogical content knowing), TPCs(teacher professional constructions), CoRe(content representation) and PaP-eRs(pedagogical and professional-experience repertoires) as constitutive units, depending on the subject areas or contents. Also suggested in this research are the knowledge bases assumed to be necessary for the development of secondary science teachers' professional qualities, which include general sciences, enrichment sciences, general science education, science education curricula and evaluation, facilities and resources for science education, teaching practices, research in science education.

Choi, K-J and Kwon, H-J. Sport biomechanical comparative analyses between general sporting shoe and functional walking shoe. Korean Journal of Sport Biomechanics, Vol. 13, No. 2, pp. 161-173. This study was performed to investigate the kinematic and kinetic differences between functional walking shoe(FWS) and general sports shoe(GSS). The subjects for this study were 4 male adults who had the walking pattern of rearfoot strike with normal feet. The movement of one lower leg was measured using force platform and 3 video cameras while the subjects walked at the velocity of 2/1.5 m/s. The findings of this study were as follows : 1. The angle of lower leg-ground and angle of knee with FWS was greater than with GSS at the moment of strike the floor and the moment of second peak ground reaction force. The decreasing rate of angle of ankle was smaller in FWS from the strike phase to the second peak ground reaction force. These mean upright walking and round walking along the shoe surface. 2. The maximal increased angle of Achilles tendon and the minimal decreased angle of rearfoot were smaller in FWS very significantly(p<0.001). Thus FWS prevent the excessive pronation of ankle and have good of rear-foot control. 3. The vertical ground reaction force and the rate of it to the BW were smaller in FWS statistically(p<0.001). The loading rate was smaller in FWS, too, and thess represent the reduction of load on ankle joint and prevention of injuries on it.
