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

박건주,하정상,이준,도현철,박승권,서상덕,기병수,김진국 영남대학교 의과대학 1996 Yeungnam University Journal of Medicine Vol.13 No.1

1985년 8월부터 1996년 1월까지 중증근무력증으로 진단받은 환자 52례에 대한 임상적 고찰을 통하여 다음과 같은 결론을 얻었다. 1. 전체 환자 중 남자가 19례(35.8%), 여자가 33례(64.2%)이넜고 11세에서 20세 사이가 12례(23%)로 가장 높은 빈도를 보였다. 2. 환자의 초기증상으로는 안검하수, 복시 등의 안구증상이 37례(71.2%)로 가장 많았고 modified Osserman의 분류에 따라서도 가장 증상이 가볍고 약물치료에 잘 반응하는 1군이 36례(69.3%)로 가장 많았다. 3. 환자가 호소하는 증상의 비특이성과 회복과 재발을 거듭하는 질병의 특성으로 인해 발병이후 진단될 때까지의 시간은 비교적 오래 걸렸고 1년이상 경과하며 진단된 경우도 16례(30.8%)나 되었다. 4. 자가면역질환이 7.6%에서 동반되었는데 갑상선기능 항진증이 2례(3.8), 인슐린의존형 당뇨 2례(3.8%)였고 종격동 전산화 단층촬영소견에서 흉선의 비대가 의심되었던 환자는 6례(11.5%), 흉선종이 발견 되었던 경우는 3례였다. 5. 환자의 치료는 대부분 항콜린에스테라제나 부신피질호르몬을 병용하는 내과적 치료를 하였으며 약물의 치료에 반응이 미비하거나 악화되는 경우 혹은 종격동 전산화 단층촬영상에서 흉선의 이상 소견이 보인 경우에 2례(3.9%)에서는 흉선절제술이, 1례(1.9%)에서는 혈장여과요법이 추가 되었고 흉선절제술과 혈장여과요법이 같이 병합 치료된 경우도 3례(5.9%)있었다. 6. 전체 환자중 2명에서 자연치유의 경과를 보였으며 이들은 모두 1군이였다. 그리고 흉선절제술과 부신피질 호르몬 투여로 완치된 예가 1례있었다. The authors experienced 52 patients with myasthenia gravis who were diagnosed at the Department of Neurology, Yeungnam University Hospital from August 1985 to January 1996. The following results were obtained through diagnostic evaluation and treatment. 1. The ratio of male to female was 1:1.7 and the most prevalent age group was second decade. 2. The most common initial presentation symptom was ocular(71.2%) and the peak incidence group was stage I(69.3%) according to the modified Osserman's classification. 3. In 16 patients(30.8%), it took more than a year to diagnose due to symptoms which were relapsed and remitting. 4. Of 52 patients, 2 cases were associated with thyroid disease(3.8%) and 2 with insulin-dependent diabetes mellitus(3.8%). 5. All of those who received anticholinesterase and corticosteroid therapy were improved with the exception of 5 cases which were improved after thymectomy and/or plasmapheresis. 6. Spontaneous remission was occured in 2 cases(3.8%) of ocular myasthenia gravis. And 1 case of group II was cured through thymectomy and long-term corticosteroid therapy.

의약품 및 동물약품으로 사용되고 있는 분말유산균을 개발하고자 동물의 장에서 산성 pH 및 담즙산에 대한 내성이 강하고 대장균 생육억제력이 좋은 Enterococcus faecium L20을 분리 동정하고 이를 이용하여 고농도의 생균이 함유된 분말 유산균을 제조하였다. 분리된 균주는 pH 3.0에서 90% 이상의 내성과 0.3% 담즙산이 함유된 배지에서 100%의 내성을 나타냈으며 MRS 배지에서 대장균과 혼합배양시 24시간 이내에 대장균을 사멸시켰다. 분리된 균주를 산업용배지에서 배양한 후 동결건조시켜 분말을 만들었을 때 생균수는 5.0×0^11/g 이상이었다. 이것은 18℃에 보관하였을 경우 11개월 동안 80%의 생존율을 나타내었다. In order to develop a lactic acid bacterial powder which can be used as a probiotic for human and animal, a lactic acid bacteria which has high resistance against low pH and ox-gall, and shows a good growth inhibition against low pH and ox-gall, and shows a good growth inhibition against E. coli, was isolated from an animal intestine and characterized. The isolated strain was identified as Enterococcus faecium. It had more than 90% of survival at low pH for 2 hours and almost 100% of survival in the presence of 0.3% ox-gall. When co-cultured with E. coli in MRS broth, all of the E. coli cells were killed within 24 hours. The final powdered product of the isolated strain was manufactured after a freeze drying process suing an industrial media, and then checked its stability. Its storage stability was 80% for 11 months at 18℃.

박종익,송선희,서동우,장현종,이종국,장안기,김윤,이철,홍진표 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.3

연구목적 : 정신분열병 외래 환자의 직접 비용과 간접 비용을 추산해 보고, 의료 자원의 적절한 운용과 효과적인 배분을 위한 보건 정책의 기초자료로 사용하고자 한다. 방 법 : 정신분열병 진단을 받은 289명의 환자를 대상으로 6개월간 외래를 방문하면서 사용한 의료비와 시간을 조사하여 직접 비용을 추산하였고, 이 기간 동안 소실된 생산성을 간접 비용으로 환산하였다. 만성질환인 관상동맥 질환을 앓고 있는 환자 82명을 대조군으로 하여 비용을 비교하였다. 결 과 : 정신분열병 환자의 실업률은 72.1%였으며, 직장을 가지고 있는 경우에도 단순노무직의 비율이 64.5%로 매우 높았다. 정신분열병의 직접 비용은 평균 81.5만원으로 관상동맥 질환의 평균 71.5 만원보다 상대적으로 많이 추산되었으나 유의하지는 않았다. 간접 비용은 평균 645.6만원, 258.9 만원으로 정신분열병군이 2.5배 정도 높았다. 결 론 : 정신분열병은 다른 만성질환에 비하여 상대적으로 매우 고비용이 요구되는 질환이며, 보다 체계적인 비용의 추산을 통하여 양질의 정신 보건 서비스를 제공할 수 있는 토대가 마련되어야 할 것이다. Objectives : We have aimed to estimate the direct and indirect costs of treating out-patients with schizophrenia in Korea, to use this fundamental data for the effective management and proper distribution of the medical resource. Method : To estimate the direct cost, we surveyed the medical cost and time of two hundred and eighty-nine out-patients with schizophrenia for six months. And the lost productivity as many months was converted into the indirect cost. Those of eighty-two coronary heart disease patients were also estimated as a comparison group. Results : An unemployement rate of schizophrenic patients was 72.1 percent. Moreover the ratio of the laborer in the sample was, even if employed, 64.5 percent. The mean direct cost of schizophrenic patients was, about 815,000 won, higher than that of coronary heart disease, 715,000 won however it was not statistically significant. The former was also estimated 2.5 times more than the latter for the indirect cost, or 6,456,000 won versus 2,589,000 won. Conclusion : Schizophrenia is a relatively costly illness compared to other chronic illness, so the systematic estimation of the cost is necessary to provide mental health service of high quality.

This study was carried out to test the body fat breakdown during topical seaweed extract treatment and in combination with the aerobic exercise. Of 20 female obesity subjects, ten treated a cream types of seaweed extract(control group) and ten treated a placebo cream(placebo group). Topical treatment of each sample was designed for 4 weeks, and treated with 2 times a day about 10ml on the abdomen and the thigh, respectively. All subjects were participated aerobic dance half hour a day and four times a week. After 4 weeks of topical treatment and exercise, they were measured body fat, skinfold thickness, body circumference. Then venous blood samples were taken and analyzed blood cells, serum enzymes, and serum lipids. There were reduction of body weight, % of body fat, antebrachium, brachium, chest, waist, thigh circumference and abdomen thickness between pre and post treatment in both group. Especially, body weight and % of body fat significantly reduced in the subjects treating the seaweed extract than those treating the placebo. There were significant decrement in total cholesterol and LDL whereas increment in HDL and TBIL in the control group, but no significant difference in the placebo group. In conclusion, there were 7.6% of body fat reduction during 4 weeks of aerobic exercise and 21% of body fat reducement in combination of topical seaweed treatment and exercise, respectively. These results suggest that the topical treatment of seaweed extract should be very effective for fat breakdown. Especially, the body fat breakdown maximized in the combination with the topical seaweed extracts treatment and the aerobic exercise.

purpose: This study was conducted to describe qualitatively the entities of nurse's experiences in general hospitals and to suggest basic data guiding research on developing Standards of clinical nursing practice in Korea. Method: Fourteen nurses working at general hospitals with over 300 beds in Seoul were interviewed in-depth until saturation using tape-recorders and transcription. Result: The central theme of clinical nursing practice experienced by subjects was "being with clients" that means accepting client's personal character, solving client's needs and providing client-centered nursing. A also "being with clients" was felt to be the responsibility of nurses which was learned from their nursing schools. The nursing strategies performed in order to be with patients were proving skillful nursing techniques, accepting, educating, emotional support, advocating, and self-reflecting, the subjects experienced somewhat problematic affects such as difficulties in interpersonal relationship, work overload, negative image of nursing, deficit of self-confidence for nursing actions, poor working conditions, and unfair treatment. Nurses at the hospital practiced with pride when they felt that they were accepted by clients. Conclusion: Further research is needed to analysis problems in clinical practice and the comparison of nurses' experiences of clinical practice, with nurses' experiences in various settings.

어유와 pectin의 혈장 cholesterol 저하 효과에 관한 비교연구

박현서,이지숙 慶熙大學校 1997 論文集 Vol.26 No.-

The present study was designed to compare the mechanism of plasma cholesterol lowering effect of fish oil and pectin by measuring the levels of plasma lipids, hepatic cholesterol and HMG CoA reductase activity and fecal excretion of total bile acids and neutral sterol in rats. Male Sprague Dawley fats (7 weeks-old) were divided into three groups according to their fat sources, beef tallow(BT), corn oil(CO), and fish oil(FO) and then each group subdivided into three groups again depending on fiber(cellulose or pectin and fiber-free as control). Rats were fed the experimental diet containing dietary fat at 15%(w/w) and fiber at 6%(w/w) level for 20 weeks. Fish oil significantly reduced the levels of plasma total cholesterol, VLDL-Chol, LDL-Chol and HDL-Chol. Fish oil inhibited hepatic HMG CoA reductase activity compared to those of other dietary fat(p<0.05). Compared to cellulose, pectin significantly reduced the levels of plasma total cholesterol, VLDL-Chol and LDL-Chol but increased HDL -Chol level in all dietary fat groups. Pectin significantly increased the excretion of total neutral sterol in feces and lowered hepatic content of cholesterol. Pectin also significantly increased hepatic HMG CoA reductase activity. Overall, pectin could reduce plasma lipid level by interfering absorption of biliary cholesterol and bile acid, which resulting in the higher excretion of neutral sterol and bile acid in feces and increased hepatic cholesterol synthesis. However, fish oil reduced plasma lipid level by inhibiting HMG CoA reductase activity. Therfore, it is recommended to consume more fish and its product and vegetable source of dietary oil rich in ω-3 fatty acid and also more fruit and vegetable and grain product rich in fiber to reduce the risk factor against cardiovascular disease.

우리나라 소아에서의 β- Lactamase 산생 Escherichia의 장관내 존재

박현수,김경희,조양자,서인수 대한감염학회 1989 감염 Vol.21 No.2

In order to evaluate the possibility that facal E. coli might serve as a reservoir of β-lactamases for Haemophilus influenzae, Neisseria gonorrhoeae, or other members of the Family Enterbacteriaceae, 135 fecal E. coli isolates from Korean children uder two years of age were tested for resistance to ampicillin (??) and for β-lactamases activity. ?? was found in 115(85%) strains of E. coli tested. Of the 115 ?? E. coli, 87(76%) were β-lactamases producers. High rates of ?? and β-lactamases activity were found uniformly in various pathogenic types of E. coli. Our observations raise questions concerning the importance of fecal E. coli in the prevalance of β-lactamase producing bacteria in the community. Fecal E. coli of Korean children may be important in the epidemiology of β-lactamases producing pathogens in humans.
