This study was done, based on a survey of those nurses working in the three general hospitals in Daejon City from July 24th to Aug. 3th, 1989, to analyze the job satisfaction of the nurses at each unit of the hospitals, and the subsequent problems. Out of 510 survey sheets, in total, 471 copies retrieved (retrieval rate 92.4%). But 36 copies were discarded, because of their improper answers, so only 435 copies were adopted for this analysis as study materials. Through SPSS program, the following conclusions were drawn out of frequency, ANOVA-test, Stepwise Multiple Regression, etc. 1. meaningful differences were statistically turned out to exist among working hospitals(p<.001), scholastic achievements (p<.01), position(p<.05). the motives for working at the present unit(p<.05), movability from the present job(p<.001) of the relationship between general characters and job satisfaction. 2. meaningful differences existed, in the relationship analysis of the of nursing job and satisfaction, among the motives for choosing the nursing job(p<.05), the motive for choosing the present job(p<.05), the satisfaction from carrying out the nursing job(p<.05), and the expectational term for carrying out more nursing jobs(p<.01). 3. The average job satisfaction at each unit was turned out as follows ; Hemodialysis unit 3.349, OBGY and PED unit 3.226, Psychological unit 3.194, NR and DEL unit 3.144, OR and Recovery unit 3.131, OPD 3.110, ICU 3.049, GS unit 3.043, ER 3.023, MI unit 2.966, and it has a meaningful statistical difference (p<.001). 4. Job satisfaction elements and the job satisfaction of each unit were determined through the work's contents (p<.001), communications (p<.01), promotion (p<.05), professionalism (p<.05), sense of attachment(p<.05), working conditions (p<.01). relationship with co-workers (p<.001), relationships with doctors and other nurses(p<.001), relationships with superiors (p<.001), and the welfare system(p<.01) 5. Through the analysis of the relationship between the job satisfaction elements and movability, it was proved that those who disapprove changing units(average 3.161) showed a higher job satisfaction than those who approve changing units(average 2.964). And the relationship reflected social position(p<.05), stability(p<.05), working contents(p<.001). communications(p<.05) promotion(p<.001). sense of values(p<.05). sense of attachment(p<.001), working conditions(p<.001), relationships with superiors(p<.01), relationships with co-workers(p<.01), relationships with doctors and other nurses(p<.05), and the welfare system(p<.001). 6. The primary predicative element influencing job satisfaction was movability form the present job. Secondary predictive elements showed working hospitals, working units, position, motives for choosing a nursing job and the expected term of working as a nurse, comprised about 16.5% of total elements.

Tsutsugamushi disease is an acute febrile illness caused by Orientie. tsutsugsmushi. It is characterized by fever, myalgia, lymphadenopathy, and rash. And it can be easily diagnosed by characteristic eschar and serologic testing. Nearly all of the patients with tsutsugamushi disease improve with antibiotics such as doxycycline. However, the fatality rate of untreated cases is seven to ten percent. Splenic infarction is not common disease which is caused by occlusion of the main splenic artery or any of its branches. It is mainly caused by emboli that arise from cardiovascular disease, but sometimes by regional thrombosis associated with leukemia, myeloproliferative disorder, sickle cell anemia, pancreatitis, splenic torsion and septicemia. We experienced one case of tsutsugamushi disease with splenic infarction, which was improved after doxycycline treatment finished.

시기능 향상을 위한 시각장애인용 전자시력보조장치의 개발
이용천,유영기,오춘석 선문대학교 ·중소기업기술지원연구소 2002 선문공대 연구/기술 논문집 Vol.7 No.1
최근 의료기술이 발달함에 따라 평균연령이 증가하면서 노인성변화나 변성에 의한 시력장애가 많아지고 사고에 의한 시력장애가 발생함에 따라 시각재활을 필요로 하는 시각장애인의 수는 현저히 늘어가고 있다. 질환에 대한 치료 못지 않게 중요한 것이 장애에 대한 재활이다. 시각장애인이 시기능을 향상시킬 수 있는 대표적인 것이 시력보조기구를 사용하는 것이다. 하지만, 각자 시각 장애에 대한 원인이 다른 환자들은 이미 상용화된 저시력 기구나 장비로 일상생활에 필요한 충분한 시기능 향상을 얻지 못하고 있다. 더구나 우리나라에서는 저시력에 대한 연구가 미비한 상태로 대개의 보조기구들은 전적으로 수입에 의존하고 있는 실정이다. 최근 국내의 한 기업이 시각장애인용 전자시력보조장비를 개발하였지만 고가이면서 부피가 크고, 머리에 착용하는 HMD형이기 때문에 시각장애인들이 활동을 하는데 있어서 불편하고 사용자가 국한된다는 단점을 가지고 있다. 본 연구에서는 앞에서 언급한 단점들을 보완하여 많은 시각장애인들이 사용할 수 있는 소형이면서 저가의 목걸이형 전자 시력보조장치를 개발한다. The number of persons with defective vision by senile change or degenerative illness has been increased remarkably as the life expectancy of a person has enhanced a lot with the advent of advanced medical technology. The number becomes still higher with the number of accidents. Now rehabilitation has become more important than cure. The normal method of improving visual ability of a person is to use the visual enhancement system. However, commercially available systems are not sufficient for the proper enhancement of differently caused visual obstacles. Furthermore, our country is unprepared for the research in this field and most of the enhancement equipment are imported. Recently, a Domestic Corporation has developed sightvisual enhancement equipment for low vision, but it is bulk in size and expensive as well. A person feels uncomfortable while using it dueto its size and has to be mounted on the head. In this research, we have developed a low cost, compact, neckwear type visual enhancement system that could be accessible and user friendly to all the visually impaired persons.

동종골수이식 후 혈당 및 혈중 지질농도의 변화양상 및 관련인자
이원영,강무일,오은숙,오기원,손현식,윤건호,차봉연,이광우,손호영,강성구,신완식,민우성,김춘주 대한당뇨병학회 2002 Diabetes and Metabolism Journal Vol.24 No.6
연구배경:골수이식은 비교적 젊은 연령의 환자들을 대상으로 하며 면역억제제의 사용기간이 비교적 짧으므로, 주로 고령의 만성 질환 환자에서 시행되는 고형장기이식에서와는 달리 당대사 및 지단백 대사에 있어서 많은 차이점이 있을 것으로 추측된다. 저자들은 전향적 연구를 통하여 골수이식 후 시기별로 혈당 및 혈중지단백 변화 양상을 알아보고 이와 관련된 임상인자들을 규명하고자 하였다. 방법:1998년 10월부터 1999년 8월까지 가톨릭대학교 성모병원에서 동종골수이식을 시행한 환자들 중 43명을 대상으로 이식 전 및 이식 후 1, 2, 3, 4주와 3개월, 6개월에 공복 혈당, 혈중 총 콜레스테롤, 중성지방, 고밀도지단백을 측정하여 골수이식 후 시기별 변화를 관찰하고 여러 임상인자들에 따른 차이를 알아보았다. 결과:1. 공복혈당은 골수이식 수 첫4주 동안 상승하였고 이후 감소하였으나 이식 6개월 시점의 평균 공복혈당은 이식 전보다 유의하게 높게 관찰되었다. 혈중 총 콜레스테롤은 이식 후 1주에 최고치를 형성하였고 이후 기저수준으로 회복되었다가 이식 수 3,6개월에 다시 증가하여 기저치에 비해 유의하게 높았다. 혈중 중성지방은 이식 후 1개월까지 유의하게 증가하였고 이후 감소하여, 3,6개월에는 기저치와 유의한 차이가 관찰되지 않았다. 혈중 고밀도지단백은 이식 후 2,3주에 이식 전보다 유의하게 감소하였고 이후 이식 전 수준으로 회복되었다. 혈중 저밀도지단백은 총 콜레스테롤의 변화와 매우 유사하였다. 2. 골수이식 후 6개월 시점에서 공복 혈당이 126㎎/dL이상인 환자는 7명(16%)이었다. 이들 환자들과 공복혈당 126㎎/dL 미만의 환자 36명을 비교한 결과, 공복혈당이 126㎎/dL 이상인 환자군에서 스테로이드 평균 투여량이 많았고 고밀도지단백이 유의하게 낮았다. 3. 이식편대숙주질환이 발생한 환자는 그렇지 않은 환자보다 이식 후 1, 2, 3주 및 6개월의 총 콜레스테롤이 더 낮았고, 3개월의 공복혈당이 더 높았다. 혈연골수이식 환자군은 비혈연골수이식 환자에 비해 투여된 스테로이드 용량이 더 적음에도 불구하고 이식 후 1, 2, 3주 및 6개월의 총 콜레스테롤 수치가 더 높았다. 스테로이드 고용량 투여군(하루 평균 7.5㎎기준)은 저용량군보다 이식 후 3개월 시점의 공복혈당이 더 높았으나 나머지 시점의 혈당, 혈중 지질농도에 있어서는 유의한 차이가 관찰되지 않았다. 결론:골수이식 후 초기시기에 주로 당 대사 및 지질대사이상이 관찰되며 이는 면역억제제 투여와 관련이 있음을 알 수 있었다. 면역억제제가 고용량 투여되는 합병증 발생 시 이들 대사이상에 관심을 기울여 대처해야 할 것이다. Background: In bone marrow transplantation(BMT), recipients are usually younger and immunosuppressants are open used in shorter period than in solid organ transplantation. Therefore, there might be a difference in glucose and lipid metabolism between BMT and solid organ transplantation. However, the serial changes of metabolic parameters following BMT have not been studied. Therefore, the aim of this study is to investigate the serial changes of blood glucose, lipids and the putative factors that are related with these changes after BMT. Methods: We have prospectively investigated 43 patients who underwent allogeneic BMT. Fasting plasma glucose(FPG), total cholesterol, triglyceride and high-density lipoprotein(HDL) were measured before BMT, and at 1, 2, 3, 4, 12 weeks and 6 months after BMT. The serial changes of these metabolic parameters according to clinical factors including type of BMT, mean daily steroid dosage, and occurrence of graft versus host disease (GVHD) were examined. Results: 1. Mean FPG level increased during 4 weeks after BMT and remained above basal value at post-transplant 6 months. Total Cholesterol level was increased during initial 4 weeks after BMT and was above basal value at post-BMT of 3 and 6 months. Triglyceride level was progressively increased during initial 4 weeks after BMT, but returned to basal value there after. HDL-cholesterol level was significantly decreased during initial 4 weeks after BMT, but returned to basal value there after. 2. Patients with FPG above 126 mg/dL and the other patients, the former received larger amounts of daily steroid and had lower HDL-cholesterol level. 3. The changes of metabolic parameters were different according to type of BMT, steroid dose, and occurrence of GVHD. Conclusion: Although there was increase of FPG, TC, TG and decrease of HDL-C during initial 4 weeks after BMT, these metabolic changes recovered slowly thereafter. Immunosuppressants are thought to be associated with these changes. Further observation will be needed for the long-term effect of BMT on metabolic changes(J Kor Diabetes Asso 24:689~698, 2000).

전기점성유체는 전기장내에서 유변물성이 빠르게 증가하는 현탁액이다. 전기장에 대한 물성의 응답속도가 매우 빠르고 전기장을 제거하면 원래의 유변물성을 가역적으로 가지는 특성이 있다. 그러므로 실용적인 측면에서 많은 응용분야가 있다. 전기점성유체는 자동변속기 오일에 전분입자를 첨가한 무게분율 35wt%의 분산계 ER유체를 사용하였다. 본 연구의 목적은 ER유체의 유량과 압력강하를 스트레인 게이지를 이용하여 계측하는데 있다. Electro-Rheoloical(ER) fluids are suspensions which show an abrupt increase in rheological properties under electric fields. The rheological response is very rapid and reversible when the electric field is imposed and/or removed. Therefore, there are many practical applications using the ER fluids. The ER fluid manufactured here is cousisted of starch particles dispersive ER fluid of weight fraction 35% in a automatic transmission oil. The purpose of the present study is flow rate and pressure drop measurement of an ER fluid by using strain gage.

The purpose of the study was to examine the performance level of and the cognitive factors of health-promoting lifestyle in high school girls. This study was designed to provide basic data for development of nursing plan and effective intervention program for health promotion. The results were; (1) The mean score of health-promoting lifestyle profile was 2.61 (possible range 1-4) (2) Performance level of each subscale was scored as follows, interpersonal support(3.01), nutrition(2.74), self-actua!ization(2.68), stress management(2.55), health responsibility(2.35), and exercise(2.11). (3) The mean scores of the study variables (possible range 1-5) were relatively high in this sample, the mean of self-efficacy was 3.24; health locus of control was 2.97; perceived health status was 3.03. (4) The health-promoting lifestyle profile had a significant positive correlation with self-efficacy (r=.521, p<.001), health locus of control (r=.236, p<001), and perceived health status(r=.156, p<.01). The study showed the needs to intervene to improve the performance of health-promoting lifestyle of high school girls. Further study is recommended to develop and apply health improvement program especially for less performed dimensions such as exercise and health responsibility. Also, it is recommended to examine other cognitive-perceptual factors influencing health-promoting lifestyle.
