저자들은 충돌 증후군 진단하에 관절경적 견봉하 감압술 중 우연히 발견된 Buford 복합체를 가진 환자를 본 후, 술후 이 환자를 추시한 결과가 Buford 복합체가 없는 다른 환자의 경우와 크게 다르지 않은 것을 보고, 충돌 증후군의 증상을 보이는 환자에서 삭형 중 견와상완 인대와 전상방견와 순의 결여가 있는 경우 이 복합체가 술후 예후에 영향을 미치지 않는 것으로 결론을 내리고 이를 보고하는 바이다.

Objectives This is one of the manuals of East-west integrative medicine which was created by the Committee on integrative medicine of Chung-Yeon Korean Medicine Hospital. The purpose of this manual is to support clinical decision making and communication during the rehabilitation of patients after shoulder surgery. Methods The drafting was done by two rehabilitation specialists in Korean medicine. After a rehabilitation specialist in western medicine reviewed the draft and exchanged their ideas, a revised version that reflects the goal of consultation was made. Then the Committee agreed to adopt the manuals through the process of review and feedback in addition to face-to-face discussions. Results This manual describes clinical decision making for rehabilitation after arthroscopic rotator cuff repair, SLAP repair, and arthrolysis. Therefore it contains the schedule of rehabilitation treatment through the surgical technique, general goal of the rehabilitation by phase, guide for patients and postoperative infection management. Conclusions The proposal of this manual has a significance for it provides information about decision making process and contents of treatment in one medical institution for East-west integrative rehabilitation treatment after shoulder surgery.

The brand sound of vehicle diesel engine is recently one of the important advantage strategies in the automotive company. Because various noise components masked under high frequency level can be audible in quieter driving situation. Many researches have been carried out for subjective and objective assessments on vehicle sounds and noises. In particular, the interior sound quality has been one of research fields that can give high quality feature to vehicle products. Vehicle interior noise above 500 Hz is usually controlled by sound package parts. The materials and geometries of sound package parts directly affect on this high frequency noise. This paper describes the sound quality evaluation method for the vehicle diesel engine noise to establish objective criteria for sound quality assessment. Considering the sensitivity of human hearing to impulsive sounds such as diesel noise, the human auditory mechanism was simulated by introducing temporal masking in the time domain. Furthermore, each of the human auditory organs was simulated by computer codes, providing reasonable analytical explanations of typical human hearing responses to diesel noise. This method finally provides the sound quality index of vehicle diesel engine noise that includes high frequency intermittent offensive sounds caused by impacting excitations of combustion and piston slap.

A new method for ship Inner Shell optimization, which is called Parametric Inner Shell Optimization Method (PISOM), is presented in this paper in order to improve both hull performance and design efficiency of transport ship. The foundation of PISOM is the parametric Inner Shell Plate (ISP) model, which is a fully-associative model driven by dimensions. A method to create parametric ISP model is proposed, including geometric primitives, geometric constraints, geometric constraint solving etc. The standard optimization procedure of ship ISP optimization based on parametric ISP model is put forward, and an efficient optimization approach for typical transport ship is developed based on this procedure. This approach takes the section area of ISP and the other dominant parameters as variables, while all the design requirements such as propeller immersion, fore bottom wave slap, bridge visibility, longitudinal strength etc, are made constraints. The optimization objective is maximum volume of cargo oil tanker/cargo hold, and the genetic algorithm is used to solve this optimization model. This method is applied to the optimization of a product oil tanker and a bulk carrier, and it is proved to be effective, highly efficient, and engineering practical.

Dynamic Load/unload (L/UL) mechanism is an alternative to the contact start stop (CSS) technology which eliminates stiction and wear failure modes associated with CSS. Other benefits of L/UL include increased areal density due to smooth disk surfaces, thinner overcoats, and lower head flying height Improved shock resistance due to elimination of head slap, and reduced power consumption. Inertia latch mechanism becomes important for mobile disk drives because of non operating shock performance. Various types of latch designs have been introduced in hard disk drives to limit a rotary actuator from sudden uncontrolled motion. In this paper, a single spring inertia latch is introduced for a small form optical disk drive, which uses a rotary actuator for moving an optical pick-up. A new small inertia latch with single spring is designed to ensure both feasible and small size. The shock performance of the new inertia latch is experimentally verified.

MR arthrography is a useful modality for evaluating the labrocapsular ligamentous complex(LOLC) of the shoulder. This study was performed to describe normal anatomic variations and pitfalis in image interpretation related to evaluation of the LOLC. MR Arthrogram of 56 shoulders in 41 asymptomatic young, active volunteers were prospectively reviewed to evaluate the labral shapes. capsular insertions and images which may mimic the lesions of glenohumoral instability. The anterior and posterior parts of the labra. respectively. varied in shape: triangular$(72\%,\; 36\%)$. round $(13\%,\; 35\%)$. cleaved$(8\%,\; 1\%)$. notched$(2\%,\; 0\%)$. flat$(5\%,\; 24\%)$ and absent$(0\%,\; 4\%)$. The anterior and posterior capsular insertions. respectively. varied in sites: Mosely and Oevergaard type I$(82\%,\;62\%)$, type II$(13\%,\; 3\%)$ and type III $(5\%,\; 2\%)$. A number of pitfalls in image interpretation were discovered. Articular cartilage undercutting the labrum$(29\%)$ and middle glenohumoral ligament in proximity to anterior labrum $(5\%)$ simulated a labral tear. Joint fluid interposed in the central. superior portion of the sublabral sulci$(25\%)$ simulated a SLAP lesion. Synovial fold$(38\%)$ in axillary pouch resembled a loose body. Knowledge of normal variations and pitfalls in MR arthrogram image interpretation of labral capsular - ligamentous complex will help the orthopedist to accurately detect debilitating derangements associated with the glenohumeral instability.

Purpose: The purpose of this study is to evaluate the short-term clinical outcome of the capsulolabral repair using absorbable suture anchor in traumatic anterior instability of shoulder. Materials and Methods: From June 2000 to September 2001, 15 shoulders with recurrent anterior instability were operated with arthroscopic Bankart repair using absorbable suture-anchor 'PANALOK' (Mitek, westwood, MA), and were followed up over 1 year (average; 13 months). The mean age was 23-years. There were fourteen males and one female. The mean duration from the initial symptoms to the operation was 24 months. Associated pathologies were Hill-Sachs defect in 12 cases, SLAP in 6 cases, and partial rotator cuff tear in 2 cases. The results were evaluated by patien's satisfaction, Modified Rowe Score in regard to joint stability, mobility, pain and function in comparison with the preoperative ones, and other complications. Results: At the last follow-up, the total Rowe Score increased from 38 points to 92 points. There were no recurrence and 14 patients among 15 patients gained pre-operative level of sports activity and no other complications. Conclusion: Effective capsulolabral repair could be obtained by the absorbable anchoring without any untoward complications. This procedure is simple and safe one and this system can be a good substitute for the metallic anchor.
