The purpose of this descriptive correlational study was to define the relationship between the experience of Sanhuujori, Korean traditional non-professional postpartal care after delivery and abortion and present health status of chronic arthritis female patient who visited to outpatient clinic of rheumatic internal medicine at a hospital located in Seoul, Korea. A convenience sample of 64 women who orally agreed to be a participant and data were collected form October 1996 to May, 1997 for sis months by way of interview with semistructured questionnaire. The data were analyzed by the SPSS pc program using t-test, ANOVA and Scheffe test as a post hoc and Pearson Correlation Coefficient. The results of the study were as follows ; Mean age of participants was 53.2 years and mean number of children was 3.1. Mean frequency of abortion was 2.1 times per woman. Seventy four percentage of respondents did not have Sanhujori after abortion. The mean period of Sanhujori after delivery was 17.7, 15.2, 13.8 days from the first child to third child and shorter than that of general woman such as 20.0, 19.0, 17.3 days in the previous study. On the subjective evaluation of whether the women did Sanhujori well or not, the rate of 'did Sanhujori wrongly' was the highest rank in each child where as general woman 'did Sanhujori well' at the first child, 'moderate' at the second and third child and 'did Sanhujori wrongly' at the 4th and fifth child. The health status implies both subjective health status women perceived and the rate of complaints of physical symptom distress women are experiencing presently. The respondents of 82.5% perceived them as unhealthy or sick and 68.9% of women complained more than two symptoms. Mean number of physical symptom distress women complained was 2.33. The main sites of physical symptom distress were upper & lower extremities 69.1% including knee and hand, whole body 19.1%, neck 3.7%, waist & shoulders 2.7% respectively. The characteristics of the symptoms were mostly pain 60%, swelling 19.8%, rigidity & deformity 7.9% respectively, sensation of heat 6.8% and weakness 1.7%. Women perceived the etiology of the chronic arthritis as stress 25.8%, 'did Sanhujori wrongly' & overwork 23.4% respectively, genetic 12.9%, malnutrition, 4.8%, and aging process 3.2%. There were significant positive correlation between subjective health status and the period of Sanhujori after delivery of the second child(r=-0.22) and negative correlation with the number of child at the level of 5% of significance statistically(r=0.27). There were significant negative correlation between the rate of complaints of physical symptom distress and the subjective evaluation whether she did Sanhujori well or not at the level of 5% of significance statistically(r=-0.23). And the rate of complaints of physical symptom distress in the group of women who experienced abortion was significantly higher than that of women who did not experience it at the level of 5% significance statistically(t=2.00) In conclusion, this finding reconfirmed the possible relationship between health status of chronic arthritis female patient and the experience of Sanhujori after delivery & abortion. It provides a challenge to the professional care givers to research further on the effects of Sanhujori on the health status, health recovery after abortion or delivery from the various aspects through the crosssectional and longitudinal research for the refinement of the reality of not only as cultural phenomenon but as conceptual model for the appropriateness of intervention and quality of care for desirable health outcomes.

This correlational descriptive study sought to define the relationship between the experience of Sanhujori, Korean tradition non-professional postpartal care after delivery and abortion and present physical symptom distress of arthritis female who visited to outpatient clinic of rheumatic internal medicine at three hospital located in Seoul, Pusan, Chongju, Korea. Data from a convenience sample of 98 women who orally agreed to be respondent were collected from September 1, 1998 to October 31, 1998 for two months by way of interview with semi-structured questionnaire. Data analysis consisted of frequency, percentage, mean, S. D., Pearson Correlation Coefficient, t-test, ANOVA and Scheffe test as a post hoc by SPSS. The results of the study were as follows ; Mean age of participants as 52.8 years and mean number of children 3.3. Mean frequency of child birth was 3.1 times per woman, 67.4% of respondents had menopause, 57.0% did not have Sunhujori after abortion. The health status implies the subjective health status women perceived, which came from the three points of view of the present, comparative with other of same age and changed after delivery. The respondents of 76.1% perceived them as unhealthy and the main sites of physical symptom distress were upper & lower extremities including knee and hand 34.8%, shoulder 26.5%, waist 22.4%. Women perceived the etiology of the arthritis as 'did Sanhujori wrongly' 36.7%, 'aging process' 24.5%, 'stress' 16.3%, 'overwork' 15.3%, 'Immunocompromize' & 'physical constitution' 7.1% respectively, 'character' 3.1%, 'genetic' 2.0%, 'malnutrition' 1.0%. The mean period of Sanhujori after delivery was 20.4 at the first child and 18.1 at the second child. The higher frequency of child birth, the shorter period of Sanhujori. For the subjective evaluation of whether the women did Sanhujori well or not, the rate of 'did Sanhujori well' was the highest rank in the first child and the rate of 'did not particularly Sanhujori well' was the highest rank in the last child. There was a significant positive correlation between physical function disability and rheumatoid arthritis symptom at the level of 1% of significance statistically(r=.406). And a positive correlation between physical function disability and Sanhubyung symptom at the level of 5% of significance statistically(r=.224). There was a significant positive correlation among rheumatoid arthritis symptom, Sanhubyung symptom and menopause symptom at the level of 1%-5% of significance statistically. Most of all, the correlation between Sanhubyung symptom and menopause symptom was the higher than others. There was a negative correlation between the present physical symptom distress and experience of Sanhujori(r=.-130), however it was not significant statistically. However, there was a positive correlation between subjective health status and experience of Sanhujori at the level of 1% of significance statistically(r=.328). In conclusion, this finding reconfirmed the positive relationship between the perceived health status and experience of Sanhujori after delivery among women of arthritis. It provides a challenge to the professional care givers to study further on the effects of Sanhuiori after abortion or delivery on the physical symptom distress from the variouis aspects through the cross-sectional and longitudinal research. The strategy for the development of the appropriate intervention for primary prevention of sequele after childbirth and quality of care for desirable health outcomes for postpartal women with considering deeply on the relationship between women's health and postapartal care.

축제식 양식장에서 수차에 의한 순환효과를 재현하기 위해 수치모형을 개발하였다. 수치모형의 지배방정식으로는 2차원 수심적분 Reynolds 방정식을 사용하였고, 수차에 의한 가속도는 축력을 수차날개에 의해 밀려가는 유체의 질량으로 나눈 값으로 산정하였다. 수치모형을 적용하여 1대의 수차를 작동하고서 수차로부터 직선방향 loin 간격으로 관측된 유속자료와 비교하였다. 모형의 보정을 위해 유량보정계수와 무차원 와점성계수의 민감도를 실험하였다. 유량보정계수는 본 연구에서 처음 제시된 항으로 실험결과 15와 20에서 모형의 결과가 관측값과 가장 유사하였다. 유량보정 계수는 관측자료가 없거나 관측이 용이하지 않을 경우 효과적으로 사용할 수 있으며, 특히 수치실험에서 수차에 의해 발생하는 복잡한 수리특성을 비교적 단순하게 처리할 수 있다는 장점이 있다. Reynolds 응력을 Boussinesq 근사로 표현하는 녈 연구에 서 무차원 와점성계수는 6이 가장 적당한 것으로 계산되었다. 바람에 의한 전단효과를 파악하기 위해 유향 $0^{\circ}C,\;90^{\circ}C,\;180^{\circ}C$ 그리고 풍속 0, 2.5, 5와 7.5m/s 조건의 경우를 비교하였다. 풍향이 수차에 의한 제트류 방향과 평행하거나 정반대일 경우 유속변화는$1\%$ 이하이나, 제트류에 직각으로 향할 경우 제트류 좌우의 와류는 풍향에 따라 위치가 뚜렷이 바뀌며, 유속은 약 $4\%$까지 감소하는 것으로 나타났다. 유속변화 $4\%$는 바람응력 외에 호지의 기하학적 평면구조 혹은 변장비 등에 따른 효과도 포함하는 것으로 생각되었다. 호지에 미치는 바람에 의한 유속변화가 $4\%$ 이하인 것으로 보아, 바람웅력의 영향은 매우 미약한 것으로 나타났다. 그러나 호지의 기하학적 특성과 관련한 와류형성 기구에 대해서 바람이 미치는 효과는 무시할 수 없는 것으로 생각되었다. 모형은 또한 축제식 양식장 2곳에 적용하였다. 양식장 호지 A와B는 각기 변장비 1.05와 0.68, 면적 1.02ha와 0.66ha 그리고 평균수심 1.2m를 갖는다. 각각의 호지에 수차 4대를 작동하고서 관측된 유속과 수치모형을 적용한 계산결과를 회귀 해석하였다. 호지A에서 유향 및 유속의 상관계수는 각기 0.8928, 0.6782이며 호지 B의 경우 각기 0.8539, 0.7071인 것으로 나타났다 따라서 본 연구에서 사용된 모형은 호지의 순환특성을 비교적 잘 재현하였으며, 향후 수차운영과 양식호지의 수질관리에 관한 유용한 도구로 사용될 수 있을 것으로 생각하였다.

기존 철근콘크리트 구조물에 대한 보강 방법으로서 강판접착공법은 강판의 박리나 rip-off 등 조기 파괴의 문제점을 안고 있음에도 불구하고 가장 널리 이용되고 있다. 그러나, 아직까지도 이러한 조기 파괴 문제점은 강판 단부의 접착계면 주위의 국부적인 파괴메커니즘 관점에서 파악되지 않고 있다. 그러므로, 이 연구에서는 보강판의 파괴 메카니즘을 구명하고 접착계면에서의 박리기준을 제시하는 것을 목적으로 하고 있다. 이러한 목적으로 두 가지 방법에 의한 광범위한 실험이 수행되었는데, 그 하나가 순수 전단력이 작용하는 상태를 고려한 double lap pull-out test이고, 또 다른 하나는 휨과 전단이 동시에 작용하는 상태를 고려한 half beam test이다. 주요 실험변수로 강판의 두께, 접착제의 두께, 부착길이, 그리고 단부 처리방법 등을 채택하였으며, 이를 토대로 하여 각 변수에 의한 영향을 다각도에서 분석하였다. 강판의 길이방향으로의 변형률을 측정하여 그로부터 접착계면에서의 전단응력을 계산하였으며, 콘크리트와 강판의 상대 변위를 측정하여, 접착계면의 전단계수를 얻고자 하였다. 이러한 실험 결과를 이용하여 비선형 유한요소 해석결과와 비교를 통하여 실험의 검증 및 강판의 단부 접착계면에 발생하는 전단응력 및 법선응력을 도출하였다. 해석결과 최대 하중뿐만 아니라 균열패턴 등도 실험결과와 잘 부합되는 것으로 나타났다. 최종적으로, 해석으로부터 얻은 최대 전단응력과 법선응력의 관계를 이용하여 접착계면의 박리가 발생하는 기준치를 제시하였다. 이러한 연구 결과는 강판 보강된 콘크리트 휨부재에 대하여 보다 현 실적인 설계 및 해석을 가능케 할 것으로 사료된다.mitted) = 369.4$_{A}$V sub p/ - l237.8 ＜기중양생>lpha$), head separation factor($\beta$), tail separation factor((equation omitted))값이 증가하였다.C$였다.$였다.X>였다..X>였다.할 것으로 생각되었으며, 향후 더 많은 환자들을 대상으로 장기간에 걸친 임상적인 연구가 필요할 것으로 생각되었다.ang with P. japonica Powder had the least sweet taste.
