목적: 관절경적 경건 봉합술을 시행한 회전근 개 관절내 부분 파열 환자에 대해 임상적 결과를 분석 보고하고자 하였다. 대상 및 방법: 2006년 4월부터 2010년 1월까지 회전근 개 관절내 부분 파열로 진단되어 관절경적 수술을 시행받은 총 31예의 환자 중 경건 봉합술 (transtendon suture technique)을 시행하고 추시가 가능하였던 24예의 환자를 대상으로 하였다. 환자의 수술 시 평균 연령은 55세 (27~75)였고, 평균 추시 기간은 37개월 (19~64)이었다. 남자가 10예, 여자가 14예였으며 24예 모두 6 mm 이상 파열된 Ellman 등급 3에 해당하였고, 결과 분석은 관절 운동범위, VAS, ASES, Constant 점수를 이용하여 분석하였다. 또한, 영상학적 결과는 초음파를 시행하여 평가하였다. 결과: 평균 전방 거상 범위는 수술 전 150.2 (±6.67)도에서 최종 추시 시 170 (±5.32)도로 향상되었고 평균 VAS 점수는 수술 전 7.38 (±1.38)점에서 최종 추시 시 3 (±1.38)점으로 감소하였다 (p<0.001). Constant 점수는 수술 전 49.25 (±5.65)점에서 최종 추시 시 73.81 (±5.64)점으로 향상되었으며, ASES 점수는 수술 전 39.59 (±12.27)점에서 최종 추시 시 80.56 (±11.36)점으로 향상되었다 (p<0.001). 최종 추시시 만족도 면에서 24예 중 21예에서 결과에 만족한다고 하였으며, 3예에서는 약간의 동통으로 인한 불만족을 나타내었다. 초음파 검사 상, 22예에서 (91.66%) 재파열 소견이 없이 치유되었고, 2예에서 (8.34%) 증상은 호전되었으나 수술전보다 파열이 증가하여 완전파열로 진행한 소견을 보였다. 결론: 회전근 개 관절 내 부분 파열 환자에 대해 관절경적 경건 봉합술을 시행하고 최소 1년 6개월 이상의 추시에서 양호한 임상적 및 영상학적 결과를 보였다. Purpose: To analyze clinical results of arthroscopic trans-tendon repair in a partial articular-side rotator cuff tear. Materials and Methods: Of 31 patients presenting with partial intra-articular rotator cuff tears between April 2006 and January 2010, we selected 24 who had received arthroscopic trans-tendon repair. The average age of patients was 55 (27~75) and the average follow-up period was 37 months (19~64). There were 10 men and 14 women and all had at least a 6 mm tear categorized as Ellman grade 3. Change in range of motion, VAS, ASES, Constant score, and ultrasonographic findings were evaluated postoperatively. Results: The average forward elevation range prior to surgery was 150.2 (±6.67) and it improved to 170 (±5.32) by the last follow-up (p<0.001). The average VAS score prior to surgery was 7.38 (±1.38) and it decreased to 3 (±1.38) (p<0.001). The Constant score before surgery was 49.25 (±5.65) and it increased to 73.81 (±5.64) by the last follow-up (p<0.001). The ASES score before surgery was 39.59 (±12.27) and it increased to 80.56 (±11.36) (p<0.001). At the last follow-up, 21 of the 24 patients were satisfied with the result. However, 3 patients were unhappy and had mild pain. On ultrasonography, 22 patients (91.66%) showed improvement without re-rupture, while the other 2 patients (8.34%) showed an with improved symptoms. Conclusion: In a partial rotator cuff tear in an articular-side lesion, the arthroscopic transtendon suture method shows excellent clinical and ultrasonographic results for at least eighteen months.

This study was to introduce arthroscopic coracoclavicular ligament reconstruction for acromioclavicular dislocation using by TightRope(R) and to report the result. This study evaluated 15 patients who were treated with arthroscopic coracoclavicular ligament reconstruction from October, 2007 to June, 2008. There were 6 patients in third type and 9 patients in fifth type. We inserted arthroscopy through subacromial space and operated using tying technique on clavicle after inserting TightRope(R) from superior clavicle to coracoid process. There were 6 cases of intra-articular lesions in arthroscopic findings. At radiological exam, 13 patients were maintained anatomical reduction. 2 patients showed redislocation in 6 weeks, they were reoperated. There were some advantages of this operation, which be able to reduce the postoperative pain and to check and treat the possible intra-articualar pathology of shoulder joint at the same time. we think this procedure can be a better option for coracoclavicular ligement reconstruction than open procedure.

목적: 보존적 치료에 반응하지 않는 주관절 외 상과염 환자에 대해 관절경적 변연 절제술 및 관절내 동반 병변에 대해 치료하고 임상적 결과를 분석하고자 하였다. 대상 및 방법: 2005년 3월부터 2010년 1월까지 주관절 외 상과염으로 진단되어 6개월 이상 보존적 치료에 반응하지 않는 43예의 환자를 대상으로 하였다. 환자의 수술 시 평균 연령은 51세 (39~68)였고, 평균 추시 기간은 36.7개월 (18~72)이었다. 남자가 15예, 여자가 28예였으며 결과 분석은 Visual Analog Scale (VAS)과 Mayo Elbow Performance Score (MEPS)를 이용하여 분석하였다. 결과: 관절내 활막염은 11예 (26%), 관절내 유리체는 2예에서 관찰되었으며, 평균 VAS 점수는 수술 전 7 (±0.7)점에서 최종 추시 시 1 (±1.0)점으로 감소하였고, MEPS는 수술 전 45 (±10.2)점에서 최종 추시 시 93 (±10)점으로 향상되었다 (p<0.0001). 43예 중 41예에서 MEPS 75점 이상의 만족할 만한 결과를 얻을 수 있었고, 75점 미만을 보인 2예에서는 동통으로 인한 불만족을 나타내었다. 결론: 보존적 치료에 반응하지 않는 주관절 외 상과염 환자에 대해 관절경적 변연 절제술 및 관절내 동반 병변에 대해 치료하고 최소 18개월 이상의 추시에서 양호한 임상적 결과를 보였다. Purpose: The purpose of this study was to evaluate the clinical result of arthroscopic debridement with treatment of associated intra-articular lesions in lateral epicondylitis patients who did not response to conservative treatment. Method: Between March 2005 and January 2010, 43 patients who were diagnosed with lateral epicondylitis and did not response to conservative treatment over 6 months were selected. The mean age of the patients was 51 years (39~68 years) and the mean follow up period was 36.7 months (18~72 months). Among the 43 patients, 15 were male and 28 were female. They were evaluated by visual analog scale (VAS) and Mayo Elbow Performance Score (MEPS). Results: Intra-articular synovitis was found in 11 cases (26%) and intra-articular loose body was observed in 2 cases. The average VAS score was 7(±0.7) preoperatively and decreased to 1(±1.0) at last follow up. MEPS was 45(±10.2) preoperatively and increased to 93(±10.0). At last follow up, 41 of the 43 patients showed satisfaction (MEPS <75) and 2 showed dissatisfaction (MEPS≥75). Conclusion: There was a better outcome at 18 months follow up after arthroscopic debridement with treatment of associated intra-articular lesion in lateral epicondylitis patients who had not responsed to conservative treatment.

The Internet is the key foundation of telecommunication and knowledge information of the twenty-first century. Thus, to vitalize the internet is the most basic and important factor for our society to make the transition to the information society, and it can be the groundwork to improve the national competitiveness ultimately. In this regard, now it is essential not only to expand in quantity of the Internet, but also to insure its substantiality. In line with this, it, which centers on marketing 4p's(product, price, place, promotion), can be summed up as follows: First, a product type for market creation should be made to change the market primarily and form a new market. Second, advanced products, whose functions can be improved and added. to the extent that an existing business form is not changed, are necessary, and the development of new products must arranged swiftly and flexibly.

최윤홍,한승오 호남대학교 2003 호남대학교 학술논문집 Vol.24 No.1

In order for successful e-CRM, customer data needs to be gathered and analyzed, a long-term viewpoint is necessary and a consensus on the importance of e-CRM must be obtained. The strategies for the improvement of e-CRM in the networked environment are like the following. First, it must be approached strategically. Second, efficiency of sharing and usage of obtained information must be increased. Third, proper personification (customization) must be carried out. Fourth, goal-oriented preliminary CRM must be managed. Fifth, partners must be utilized effectively and aggressively. Proper results of CRM(Customer Relationship Management) cannot be obtained by just simply applying the system, but requires constant modification and improvement. Effective usage of CRM will only occur when constant effort and research is put into it by the company.

비선형 유한요소법을 사용한 고무 마운트의 정특성 해석에 있어서 체적 탄성 계수의 역할

여태인,최윤홍 울산대학교 1999 공학연구논문집 Vol.30 No.2

고무 스프링의 정 스프링 상수를 해석하기 위해 비선형 유한요소법을 사용할 때, 고무의 구성 방정식은 초탄성 재료 모델로 표현한다. 일반적으로 엔진 마운트의 설계를 위한 초탄성 모델의 재료 상수들은 일축 압축 시험과 단순 전단 시험 결과만을 이용하여 구해진다. 그러나 체적 시험을 생략하고 고무를 비압축성으로 가정한 비선형 유한 요소 해석 결과는 매우 부정확한 결과를 가져올 수 있다. 본 연구는 수치 해석 결과에 미치는 체적 탄성 계수의 영향을 조사하여, 엔진 마운트의 형상 계수가 클 때는 체적 변형율의 정확한 측정이 다른 두 물성치의 측정과 마찬가지로 중요하다는 것을 보이고 있다. When a nonlinear finite element analysis is used to find the static spring constants of a rubber spring, the constitutive equations of the rubber are represented by a hyperelastic model, of which material constants are determined from the different types of material tests. Uniaxial compression and simple shear tests are usually chosen due to their experimental conveniences, while volumetric test is often underestimated and omitted. But the hyperelastic model obtained from the two kinds of tests alone can result in rather poor performance for a certain engine mount when the rubber is assumed to be incompressible in teh finite element procedure. This study investigates the influences of bulk modulus, which are found to be as equally important as other two material properties, on the numerical results when the form factor of the mount becomes large.
