세라믹은 마찰계수 및 마모에 대한 저항성에 있어 금속-폴리에틸렌 관절보다 우수 하지만 소성 변형 범위가 매우 적어(brittle) 깨지기 쉬운 특성을 가지고 있다. 알루미나 세라믹 골두의 파손은 드물게 보고되고 있으며 골두 파손 시 대퇴 스템의 Morse taper의 소성 변형으로 인해 금속-폴리에틸렌 관절면을 이용한 재치환술을 시행하는 것이 좋은 결과를 보인다고 보고되고 있지만 재치환술 후 남아있는 세라믹 입자에 의한 관절면의 마모에 대한 보고는 매우 드물다. 저자들은 양측성 대퇴골두 무혈성 괴사로 세라믹-세라믹 관절면을 이용한 인공 고관절 전치환술 후 세라믹 골두 골절이 발생한 환자에서 금속-폴리에틸렌 관절면을 이용하여 재치환술을 시행하고 추시 관찰 중 남아있던 세라믹 입자에 의한 제 3개체 마모(third body wear)로 발생한 과도한 metallosis 1예를 경험하였기에 이를 보고하고자 한다. A ceramic articulation thought to be superior to metal-on-polyethylene due to its extremely low coefficient of friction and its potential for resistance to wear. But ceramic is brittle, which makes it theoretically susceptible to fracture. Although many authors have reported that metal-on-polyethylene articular pairing had good results after a ceramic head fracture, there have been few reports about complication due to the remaining ceramic particles after revision surgery. We report here on a case of severe metallosis that was thought to be due to third body wear by the remaining fractured ceramic particles after revision total hip arthroplasty.

목적: 골불안정성 원위 요골 관절내 골절에서 T형 잠김 압박 금속판을 이용한 군과 외고정 장치를 이용한 군의 결과를 비교하고자 하였다. 대상 및 방법: T형 금속판 내고정술을 시행한 22예의 평균 추시 기간은 24개월이었고, 외고정술을 시행한 20예의 평균 추시 기간은 28개월이었다. 치료 결과의 판정을 위해 Mayo Wrist Scoring System을 이용한 임상적 평가 및 방사선학적 평가를 시행하였다. 결과: 임상적 결과는 T형 금속판을 이용한 군에서 평균 84.6점, 외고정 장치를 이용한 군에서 평균 80.5점이었다. 방사선학적으로는 최종 추시 시의 T형 금속판을 이용한 군에서 요골 길이가 10.5 ㎜, 요측 경사가 21.7도, 수장측 경사가 9.8도, 관절내 층 형성이 0. 25 ㎜였으며, 외고정 장치를 이용한 군에서 요골 길이가 10.1 ㎜, 요측 경사가 20.3도, 수장측 경사가 6.3도, 관절내 층 형성이 0.73 ㎜였다. 결론: 두 군 모두 임상적으로 만족할 만한 좋은 결과를 보였다. 그러나 T형 금속판을 이용한 군에서 술 후 조기 관절 운동으로 일상 생활로의 복귀가 빨랐으며, 정확한 해부학적 정복으로 인해 수장측 경사, 관절내 층 형성에 있어서 통계학적으로 의미 있는 좋은 결과를 나타냈다. Purpose: To compare the outcomes between T-locking compression plate (T-LCP) and external fixator (EF) for unstable distal radius intraarticular fractures. Materials and Methods: We retrospectively analysed the results in 22 cases with T-LCP, 20 cases with EF. We evaluated the clinical results according to the Mayo Wrist Scoring System, radiographic results. Results: The mean score was 84.6 in the T-LCP group and 80.5 in the EF group respectively. Final radiographic measurements for the T-LCP group averaged 10.5 ㎜ radial length, 21.7˚ radial inclination, 9.8˚ volar tilt and 0.25 ㎜ intraarticular step-off. The EF group averaged 10.1 ㎜ radial length, 20.3˚ radial inclination, 6.3˚ volar tilt and 0.73 ㎜ intraarticular step-off. Conclusion: Both groups showed satisfactory final clinical outcomes. But T-LCP group allowed return to daily living, resulting in early postsurgical wrist motion. By the anatomical reduction, final volar tilt, intraarticular step-off were statistically better in the T-LCP group.

임상경력제도 적용에 대한 간호사의 인식조사

정수원 대한간호협회 2005 대한간호 Vol.44 No.6

The clinical ladder system was established in the 1970s to retain the qualified and experienced nurses m the United States and has contributed to improve quality of care, job satisfaction, professional development of nursing staff and so on. Recently we are preparing to adopt the clinical ladder system widely used in the U.S. There are, however, many differences between our clinical environment and that of the U.S. Therefore, we have to review various cases of other countries and to find out the differences in order to adopt it properly. This study is a descriptive study to the recognition of registered nurses (RNs) about the adoption of the clinical ladder system. Data were collected from total 227 RNs who were working in 8 hospitals in Seoul and Kyunggi area in November 2003 by using questionnaires and analyzed by PC-SPSS program. The results of this study were as follows: 1. Most of RNs thought that adoption of the clinical ladder system was necessary and its implementation would be able to develop their clinical excellence in nursing. 2. On the ladder design and implementation, they wanted to apply it to every single nursing unit by grading the five-level of clinical practice. For the career promotion, they also wanted that RNs should be promoted to next level automatically during lower ladder period and could apply to higher levels by their choice. For the evaluation they wanted to be evaluated by committee through tests, supervisor's evaluation, peer review, and their own portfolio. To maintain one's level, they wanted all levels except the entry level to be evaluated every year. The reward should be offered to all levels except the entry level and monetary reward such as salary or wage was mostly preferred. 3. The average expectation about the claimed benefits to apply the clinical ladder system of all subjects was 3.36(0.79. Therefore, it represented the RNs' recognition about the clinical ladder system was relatively positive. The average expectation was 3.36(0.84 for the supervisors and that of staff nurses was 3.23(0.76. There was no significant difference in expectation between the supervisors and staff nurses on the adoption of the clinical ladder system (p=.288). In addition, the score in the area of professional status was highest. This represented that both supervisors and staff nurses had high expectation on the area of professional status. The average expectation was 3.22(0.72 for the intensive care unit nurses and that of general unit nurses was 3.29(0.82. There was no significant difference in expectation between working places (p=.347). The results of this study will be useful as basic data for presenting a way to apply the clinical ladder system to nursing practice in Korea, and for contributing to enhance professional development of nursing staffs, and retain the clinical expert nurses in direct patient care roles.

This article investigates both life and agony of Korean residents in Japan from the perspectives of their every life. The discussion begins with exploring the history and various definitions of 'Korean residents in Japan.' Followed is an introduction io their present legal status and situation as 'permanent foreign residents' in Japan. Then this article identifies the types of ordinary agony that Korean residents in Japan have been always facing with. To this end, the types of agony is classified as two groups, namely, survival agony and environmental agony. The first group includes the mental anguish that are related with the 'limited' use of Korean names, racial discrimination in housing, employment, and business. And the second includes the mental anguish resulting from child education, marriage, naturalization, and suffrage rights. Then this article investigates how Korean residents in Japan are coping with the various agony, most of which are caused by the racial discrimination policy of Japanese society. An interesting but melancholy finding from this investigation is the Korean residents' passive and negative mind and attitude in solving such agony. They are dealing with their agony as a personal matter, not as a common issue that the entire Korean ethnic community should meet and overcome. The examples demonstrating such mind and attitude are provided through the interviews that were conducted with major figures in the Korean community. Finally emphasizing the need for establishing information systems or organizations that could activate the interactive communication among Korean residents, this article suggests the korean community s various organizations and institutions should play more active and positive role in order to promote daily communication among the Korean residents in Japan.
