The aims of this study were to understand and to predict the determinent factors affecting the exercise behaviors and physical fitness by testing the Pender's revised health promotion model, and to help the patients with rheumatoid arthritis and osteoarthritis perform the continous exercise program, and to help them maximize the physical effect such as muscle strength, endurance, and functional status and mental effects including self efficacy and quality of life, and improve the physical and mental well being, and to provide a basis for the nursing intervention strategies. Of the selected variables in this study, the endogenous variables included the physical fitness, exercise score, exercise participation, perceived benefits of action, perceived barriers of action to exercise, activity-related affect(depression) and perceived self-efficacy, interpersonal influences(family support), situational factors(duration of arthritis, fatigue) and the exogenous variables included personal sociocultural factor(education level), personal biologic factor(body mass index), personal psychologic factor(perceived health status) and prior related behavior factors(previous participation in exercise, life-style). We analyzed the clinical records of 208 patients with rheumatoid arthritis and degenerative arthritis who visited the outpatient clinics at H university hospital in Seoul. Data were composed of self reported qustionnaire and good of fitness score which were obtained by padalling the ergometer of bicycle for 9 minutes. SPSS Win 8.0 and Window LISREL 8.12a were used for statistical analysis. Of 75 hypothetical paths that influence on physical fitness, exercise participation, exercise score, perceived benefits of action, perceived barriers of action to exercise, activity-related affect(depression) and perceived self-efficacy, interpersonal influences(family support), situational factors(duration of arthritis, fatigue), 40 were supported. The physical fitness was directly influenced by life-style, perceived health status, education level, family support, fatigue, which explained 12% of physical fitness. The exercise participation were directly influenced by life-style, education level, past exercise behavior, perceived benefits of action, perceived barriers of action, depression and duration of arthritis, which explained 47% of exercise participation. Exercise score were directly affected by perceived self efficacy. BMI, life-style, past exercise behavior, perceived benefits of action, family support, perceived health status. perceived barriers of action, and fatigue, which explained 70%. Perceived benefits of action was directly influenced by BMI, life-style, which explained 39%. Perceived barriers of action were directly influeced by past exercise behavior, perceived health status, which explained 7%. Perceived self efficacy were directly influeced by level of education, perceived health status, life-style, which explained 57%. Depression were directly influeced by past exercise behavior, BMI, life-style, which explained 27%. Family support were directly influeced by life-style, perceived health status, which explained 29%. Fatigue were directly influeced by BMI, life-style, perceived health status. which explained 41%. Duration of arthritis were directly influeced by life-style, past exercise behavior, BMI, which explained 6%. In conclusion, important variables for physical fitness were life-style, and variable affecting exercise participation were life-style. Perceived self-efficacy of exercise was a significant predictor of exercise score. BMI, Life-style, perceived benefits of action, family support, past exercise behavior showed direct effects on perceived self-efficacy. Therefore, disease related factor should be minimized for physical performance and well being in nursing intervention for patients with rheumatoid arthritis, and plans to promote and continue exercise should be seeked to reduce disability. In addition, Exercise program should be planned and performed by the exact evaluation of exercise according to the ability of the patients and the contents to improve the importance of exercise and self efficacy in self control program, dedicated educational program should be involved. This study suggest that the methods to reduce the disease related factors, the importance of daily life-style, recognition of benefit of exercise, and educational program to promote self efficacy should be considered in the exercise behavior promotion and nursing intervention for continous performance. The significance of this study is also thought to provide patients with chronic arthritis the specific data for maximal physical and mental well being through exercise, chronic therapeutic procedure, daily adaptation and confrontation in nursing intervention.

연구목적: 최근 지대주 나사에 WC/C 또는 TiN 코팅이 연구되고 있으며, 이들을 금속표면에 코팅 시 마찰계수의 감소와 부식에 대한 저항, 물리적 취약함의 해소 등의 효과를 얻을 수 있으며. 코팅된 지대주 나사에서 마모와 적합도, 풀림력이 향상되었다는 결과들이 보고되고 있다. 본 연구에서는 지대주 나사에 적용된 코팅이 나사 풀림에 미치는 영향을 알아보아 임상적으로 문제가 되고 있는 지대주 나사의 풀림현상을 해소하는데 그 목적이 있다. 연구재료 및 방법: 코팅되지 않은 타이타늄 지대주 나사와 (그룹 A) WC/C (그룹 B)와 TiN (그룹 C)으로 코팅된 지대주 나사의 10회 반복 착탈시 풀림력 및 표면의 변화를 비교해본 결과 다음과 같은 결론을 얻었다. 결과: 1. 반복 착탈 전, 그룹 A는 일정한 방향성을 가진 다소 거친 표면이 관찰되었으 나 그룹 B와 그룹 C는 코팅된 입자들이 관찰되었으며 코팅층이 전체적으로 균일하고 매끈한 모양을 나타내었다. 2. 반복 착탈 전, 그룹 B에 비해 그룹 C의 표면에서 코팅 입자의 크기가 더 크고 두껍게 코팅 된 모양을 나타내었다. 3. 반복 착탈 후, 그룹 A와 그룹 B에서는 지대주 나사 표면의 마모와 변형이 관찰 되었으며 그룹 B에서는 코팅 입자의 탈락 현상을 볼 수 있었다. 4. 반복 착탈 전과 후의 지대주 나사 무게의 변화를 측정한 결과 그룹 A가 가장 큰 감소를 보였으며, 그룹 C가 그룹 B 보다 무게의 변화가 적었으나 두 그룹간 통계적으로 유의한 차이는 없었다. 5. 그룹 B와 그룹 C는 그룹 A에 비해 높은 평균 풀림력을 나타내었고 통계학적으로 유의할 만한 차이가 있었다. 6. 그룹 A에서 그룹B 와 그룹 C보다 평균 풀림력의 감소 경향이 더욱 현저 하게 나타났다. 결론: 결론적으로, WC/C 또는 TiN 코팅된 지대주 나사는 반복적인 사용 후에도 코팅되지 않은 타이타늄 지대주 나사에 비해 뚜렷한 표면 변화를 보이지 않았으며 마모에 대한 저항성이 우수하였고 높은 풀림력을 나타내었다. 따라서 지대주 나사에 WC/C 또는 TiN 코팅을 적용 시 나사 풀림의 문제점을 개선할 수 있을 것으로 사료된다.

연구배경: 다양한 원인에 의한 호흡부전증에서 중환자실뿐만 아니라, 응급실, 일반병실에서 호흡보조와 이탈방법으로 NPPV를 사용한 환자에 대해서 임상상을 조사하고, 유용성 및 예후를 조사하고자 하였다. 방 법: 2003년 6월부터 2005년 5월까지 부산대학교병원에서 NPPV로 치료한 34명(남자 16명, 여자 18명,평균연령 58세)을 대상으로 하였다. 모든 환자의 원인질환, 치료기간, 적응 유무, 합병증 및 치료에 대한 성공 여부, NPPV 적용 전과 적용 후 2시간과 24시간 후에 생체징후, 동맥혈 가스검사를 조사하였다. 결 과: 성공 군은 24명(71%), 실패 군은 10명(29%)이었다. 성공 군은 실패 군에 비해 평균 연령, 성별, 치료기간, 생체 징후, $PaO_2$, $PaCO_2$, $SaO_2$는 큰 차이가 없었으나, 적용 전의 pH는 유의하게 높았다. 만성폐쇄성 폐질환환자의 성공률이 비만성폐쇄성 폐질환환자보다 높았으며(86% vs 53%), 2시간후 동맥혈 가스검사도 유의하게 향상하였다. 비만성폐쇄성 폐질환환자에서도 기계환기 이탈 후 NPPV를 적용하였을 때 2시간후 동맥혈검사가 유의하게 향상되었다. 합병증은 총 5건으로 안면 피부 발적 3건, 복부팽만 1건, 구강 건조가 1건이 있었으나 이로 인한 중단 예는 없었다. 결 론: 다양한 원인에 의한 호흡부전증 환자에서 호흡보조와 이탈방법으로 NPPV의 적용은 유용한 방법으로 생각되며, 적용 전의 pH와 적용 2시간 후 분당 호흡수, 동맥혈 이산화탄소 분압,동맥혈 산소 분압, 산소포화도의 향상이 성공 여부에 중요한 인자로 생각된다. NPPV 적용의 성공률을 높이기 위해 적절한 기준 및 기계를 다루는 기술과 경험, 성공 인자에 대한 평가가 필요하다.

목적: 본 연구에서는 CAD/CAM 기술로 제작한 4가지 금속하부구조물의 변연 및 내면 적합도를 비교하여 정확도 및 임상적 효용성을 알아보고자 한다. 재료 및 방법: 상악 중절치 레진모형치아를 삭제한 뒤 복제하여 Ni-Cr 합금 표준 모형을 제작하였다. 이를 공초점 현미경방식의 구강 스캐너를 이용해 12개의 STL 파일을 얻었다. CAD 프로그램 상에서 $50{\mu}m$의 시멘트 공간을 부여한 두께 0.5 mm의 금속하부구조물을 디자인하였다. Co-Cr 금속하부구조물은 다음 4가지 방법으로 제작하였다: Wax pattern milling & Casting (WM), Resin pattern 3D Printing & casting (RP), Milling & Sintering (MS), Selective laser melting (SLM). 변연 및 내면 적합도를 측정하기 위해 실리콘 복제법을 이용하였다. 측정한 결과값은 SPSS 통계 프로그램을 이용하여 일원배치분산분석(one-way ANOVA)으로 통계처리하고, 사후검정으로 Scheffe test를 시행하였으며, 5% 유의수준으로 평가하였다(${\alpha}=.05$). 결과: 변연 적합도는 WM군($27.66{\pm}9.85{\mu}m$)과 MS군($28.88{\pm}10.13{\mu}m$)이 RP군($38.09{\pm}11.14{\mu}m$)에 비해 통계적으로 유의하게 작았다. 치경부 적합도는 MS군이 RP군에 비해 통계적으로 유의하게 작았다. 축면 적합도는 WM군과 MS군이 RP군과 SLM군 보다 통계적으로 유의하게 작았다. 절단면 적합도는 RP군이 통계적으로 유의하게 작았다. 결론: Wax pattern milling & Casting, Milling & Sintering법으로 제작한 Co-Cr coping의 변연과 축면에서의 적합도가 더 우수하였다. 모든 군의 Co-Cr coping의 변연, 치경부, 축면 적합도는 임상적으로 허용할만한 범위 안에 있었다.
