This study was undertaken to grasp health-promoting behavior of the elderly and to identify self-rating health status, demographic characteristics related to them in order to facilitate nursing intervention for health promotion of the population. The subjects for this study were 225 old persons visiting five general social welfare centers located in Tague. Data were collected by self-reported questionnaires from August, 2002to February, 2003. Questionnaires were Northern Illinois University's Health Self-Rating Scale, Walker and others' health Promotion Lifestyles Profile. Analysis of the data was done by the SAS program for descriptive statistics, t-test, ANOVA, and pearson Correlation Coefficient. The results were summarized as follows: 1. There were significant differences in health-promoting behavior according to sex)t=3.28, p=.0011), marital status(F=8.98, p=.0003), and average monthly pocket money(F=4.99, p=.0007). 2. For the participation in health-promoting behavior, the mean score was 2.96 and range was from 3.40 to 2.34. The factors of high mean score were sedentary life(3.40), regular diet(3.37), and factors of low mean score were stress management(2.34), accountability for health(2.60). 3. The mean score of health self=rating was 2.19(range 4-14) and was considered low. 4. Self-rating health status was correlated positively with health-promoting behavior(r=.1783, p=.0106). On the basis of the above findings, the followings are recommended; 1. Nursing strategies need to be developed considering personal demographic characteristics of the elderly. 2. Nursing interventions enhancing self-actualization, accountability for health, stress management of the elderly must be provided.

저자들은 가와사끼병으로 IVIG 치료로 해열을 보인 후, 급격히 발병한 관절염을 보인 5명의 환아에 대해 임상적 경과, 실험실 소견 등을 조사하였다. IVIG 치료에 반응 후 평균 5.8일 후에 관절염 증상이 나타났으며, 임상적 분류상 소수 관절형 형이 3례, 다수관절형이 2례로 나타났다. 검사실 소견에서 류마토이드 인자는 1례에서 양성을 보였으나 이 후 음성으로 전환되었다. 3명에서 조사된 HLA B27은 모두 음성을 보였다. 치료로는 고용량 아스피린(2례), 비스테로이드성 소염제(이부프로펜, 3례), 스테로이드제(메틸프레드니솔론, 1례)를 사용하였다. 가와사끼병의 경과 중 정맥용 면역글로불린 치료 후 관절염이 드물게 관찰된다. 이러한 관절염은 스테로이드제를 비롯한 항염증제에 양호한 반응을 보였고 재발은 관찰되지 않았다. We evaluated the clinical and laboratory characteristics of five children with Kawasaki disease who had showed arthritis after responding to intravenous immunoglobulin(IVIG) treatment. Age distribution was between 13 months and six years of age(mean $3.2{\pm}1.6$ years). There were two males and three females. Arthritis occurred when acute symptoms were subsiding, with the average onset on day $5.8{\pm}1.8$ after final IVIG treatment. Arthritis was pauciarticular in three, and polyarticular in two. Regarding laboratory findings, one child was positive in rhematoid factor and changed to negative after two months. Three patients were examined for HLA B27 and all showed negative results. High dose aspirin(two cases), anti-inflammatory drug(ibprofen, three cases), and corticosteroids(methyprednisolon pulse therapy, one case) were used for this type of arthritis. Symptoms and signs of arthritis in all patients were improved by these therapies. There was no relapse or complications within six months. Arthritis after responding to IVIG therapy was rarely observed in children with Kawasaki disease. This type of arthritis responded well to anti-inflammatory drugs including corticosteroids, and showed no relapses.

Recently, Cycle of the product is shortened Because of diversification of consumer needs and demands for high performance & lightweight & precision of a machine part is on the increase. Therefore, In addition to increasing mould products including 3D surfaces, The interest in ball-endmill often using finish cutting has been focused. So in this study, we consider that peak point of ball-endmill is not included on cutting at inclined plane and analysis cutting force in tool at inclined plane and check temperature on cutting.

DRM에서 키 관리 기술은 중앙 집중 키 관리 방식, Enveloping 방식 등이 있다. 본 논문에서는 암호화 키를 콘텐츠에 함께 동봉하는 키 관리 방식을 기반으로 새로운 DRM 키 관리 기술을 제안한다. 제안하는 키 관리 기술은 사용자 인증에서 사용된 인증정보를 콘텐츠 암호화 키로 사용함으로 콘텐츠 암호화 키를 암호화하여 전송할 필요가 없는 장점이 있다.

Trapa pseudoincisa Nakai, an aquatic plant, was extracted with 80% aqueous MeOH, and the concentrated extract was successively partitioned with EtOAc, n-BuOH, and $H_2O$. The EtOAc fraction gave three compounds, which were isolated through the repeated silica gel and ODS column chromatographies. Based on the spectroscopic data obtained from NMR, MS, and IR, the chemical structures of the compounds were determined as cycloeucalenol (1), ursolic acid (2), and 2${\beta}$,3${\alpha}$,23-trihydroxyurs-12-en-28-oic acid (3). These triterpenoids were isolated for the first time from Hydrocaryaceae plants including T. pseudoincisa NAKAI.

PAM-STAMP is a widely used program which deals with press forming analysis. A blanking used in the press process depends on the experience of the workers. Thus it causes some waste material and demands a lot of time and many costs at the manufacturing mold. so we need to optimize of the blanking size. we have studied the optimal blanking size of the Brace Center Pillar using an Inverse module in PAM-STAMP.

This study gives the vertical motion analysis in multi-directional irregular waves using a commercial code(MAXSURF v.16) based on linear strip theory for a training ship. To verify the commercial code prior to the analysis, we guarantees the reliability of this paper's results using the commercial code by comparing with the results(Flokstra, 1974) of same hull and experimental conditions on a Panamax container. The analysis conditions are Beaufort wind scale No. 5($\bar{T}=5.46$, $H_{1/3}=2m$) based on ITTC wave spectrum, encounter angle Head & bow seas($150^{\circ}$) and Froude number Fn=0.257. Finally, we calculates heave RAO, pitch RAO and obtains the result of ship's response spectra for heave and pitch motions. In the motion response spectrum under the multi-directional irregular waves, heave motion reacts slightly high in short-crested waves and pitch motion reacts high in long-crested waves. 본 연구에서는 실습선의 다방향 불규칙파중 종방향 운동응답특성을 선형 스트립이론에 기초한 상용코드(MAXSURF v.16)를 이용하여 해석하였다. 해석에 앞서 상용코드의 검증을 위해 파나막스급 컨테이너선에 대해 실험조건과 동일한 선형과 해석조건을 적용하여 계산한 결과와 기 계산된 결과(Flokstra, 1974)가 상호 유사한 경향을 얻어 해석의 신뢰성을 확보하였다. 계산조건으로는 Fn=0.257에서 파랑외력을 ITTC 파스펙트럼에 기초한 뷰포트 스케일 5($\bar{T}=5.46$, $H_{1/3}=2m$)의 파스펙트럼을 산출하였고, 조우각은 선수사파(Head & bow seas, $150^{\circ}$)를 적용하여 상하동요(Heave)와 종동요(Pitch)의 선체운동응답스펙트럼을 해석하였다. 다방향 불규칙파에 대한 운동응답스펙트럼은 선수사파에서 상하동요의 경우는 미소하게 단파정파에서 높은 스펙트럼 분포를 보이고 종동요의 경우는 장파정파에서 높게 나타났다.
