Objective : Compare the results of CPM and PNF in recovery rates when applied as an initial physical therapy. Methods : Randomly selected 19 patients who underwent through total knee replacement surgery. 23 cases were studied and divided into 12 CPM and 11 PNF cases. CPM case was carried out for 60 minutes, a maximum allowed exercise without pain. PNF case was carried out for 20 minutes by a therapist to a patient as 'one on one'. Result : Result showed that PNF treatment was increased significantly at P<0.05 in flexor muscle strength in 8 days after the surgery. Conclusion : The study revealed that in comparison with CPM, PNF was more effective treatment increase of flexor muscle strength in rehabilitation on after total knee replacement surgery.

본 연구에서는 중소기업청의 정책자금지원 사업을 도와 줄 OLAP 데이터베이스 시스템을 구축하는 것을 목적으로 하고 있다. 정책자금을 단계적으로 지원하기 위해서는 필수적으로 이질 차원 스키마를 채택해야 한다. 따라서 본 연구에서는 단계적 정책금융을 지원하도록 하는 FREQUENCY 차원테이블을 작성한 것이다. 또한 본 연구에서는 중소기업의 크기를 측정할 모델을 작성하였는데, 이 모델은 매출액, 고용인력, 기술보유, 매출액 영업이익률, 부채 비율, 유동비율의 6가지 기업크기 측정지표로 구성되어 있다. FREQUENCY 차원을 포함한 3개 차원과 기업크기 측정모델을 사용하여 OLAP 데이터베이스 시스템을 구축한 것이다. 아울러 이렇게 구축한 OLAP 데이터베이스 시스템을 이용하여 2004년~2007년 간 기 시행된 중소기업 정책자금 지원사업의 적정성을 평가해 보고 있다. The purpose of this paper is to develop an OLAP (online analytical processing) database system that supports the SMBA (Small and medium Business Administration) policy funding. A heterogeneous dimension schema will be central in staged support of policy funds. In this paper, therefore, we designed the FREQUENCY dimension table which has a heterogeneous dimension schema structure. In this paper, we made a model of measuring SME (small and medium-sized enterprise) size first. The model is composed of six determinants of firm growth such as sales, employment, own technology, the operating profit to sales ratio, the debt ratio, and the current ratio. We developed the OLAP database system by using three dimensions including the FREQUENCY dimension, and using the model of measuring SME size. Also we assessed past decisions on policy funding in the Small Business Policy Funds Support Project (2004-2007) by using the OLAP database system.

There can be included a variety of uncertainties in all measurement results whether we can perceive or not on the causes. These uncertainties may end up in lowering the reliability of measurement results and also deteriorate the level of quality. For the purpose, we tried to combine the strengths of measurement uncertainty and measurement system analysis together to present a practical flowchart so as to verify those potential variation factors in general measurement processes. As a case study, we did an experiment and gathered data on the length between two holes of an engine cylinder head which is a core part for vehicles with a coordinate measuring machine and estimated nine uncertainty factors of it. Consequently, it was identified that the four primary factors among the nine which were related to the measurement standard, random errors or spread of the repeat measurements, differences between the coefficients of thermal expansion and the environment especially had been the influence around the laboratory. Since it is impossible to analyze the equipment and appraisal variations respectively through the only measurement uncertainty, we have used the measurement system analysis following the flowchart. Showing the result of being just about 0.5 % lower for the appraisal variation, and the equipment variation occupied about 7% for the total Gage R&R. Through this research, we have come to a conclusion that much more detail analysis on variation factors can be possible to be identified in measurement processes by using the developed flowchart which is composed of measurement uncertainty and measurement system analysis. Therefore, we expect engineers who are involved in quality and measurements to utilize this developed method.
