Purpose: This study examined the effects of early stabilization exercise focused on the scapulothoracic joint on the recovery of surgical patients due to rotator cuff tear. Methods: The subjects were 30 patients divided randomly into two groups. Group I consisted of 15 patients who practiced shoulder joint stabilization exercises, including glenohumeral joint movement. Group II consisted of 15 patients who practiced scapulothoracic joint stabilization exercises, excluding glenohumeral joint movement. The duration of stabilization exercise was 30 minutes for one day, five days a week, and five weeks. To measure the dependent variables, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, range of motion (ROM), dynamometer of measured grip were used. Results: The DASH, ROM, and grip power were compared. A significant difference was observed before the intervention in each group (p<.05), and there was no significant difference between group I and group II (p>.05). Conclusion: Both shoulder joint and scapulothoracic joint stabilization exercises were effective after the intervention compared to preintervention, but there was no difference between the two groups. Unlike many recent studies on the initiation of stabilization exercises, this study allays the concerns between the advantages of 'early exercise' and oppositions of previous studies about 'early exercise'. Nevertheless, further research regarding these subjects is needed.

Purpose: The present study was to investigate effects of scapular position and pain on a trunk stabilization exercise with gym ball for patients with arthroscopic rotator cuff repair. Methods: Subjects were patients after 2 weeks of rotator cuff repairs. Subjects were randomly assigned to conservative treatment group (CTG, n=10) or trunk stabilization with gym ball group (SBG, n=10), and participated one of those groups for 2 weeks. Measurements about pain and scapular position were assessed in before and after treatment programs. Results: Pain reduced in both rest and night in SBG compared to CTG. In the case of scapular position, decreased scapular retraction (increased protraction) was found in CTG and vice versa in SBG. Reduced scapular anterior tilting was also found on SBG. Conclusion: The present study showed that early performed trunk stabilization with gym ball could bring a scapular alignment that increases subacromial space and reduces pain. This suggests early trunk stabilization with gym ball programs to restore shoulder functions for patients with rotator cuff repair.

본 연구에서는 국내산 포도주의 감산 연구를 위해 Campbell Early를 이용하여 control, precipitation, cold stabilization, MLF, carbonic maceration, cold fermentation과 같이 6가지 다른 방법으로 산도 감소 효과를 실험해 보았다. 6가지 방법으로 제조한 포도주가 $4-5^{\circ}Brix$의 당도와 6.8-7.7%의 알코올 함량을 나타냄으로써 산도 감소를 위해 발효 방법을 달리해도 정상적인 발효가 진행되었음을 확인할 수 있었다. 그리고 숙성 중에 pH와 총산, 유기산 함량을 측정하여 감산의 정도를 알아본 결과 cold stabilization을 제외하고는 각 포도주들이 control보다 pH는 증가하고 총산은 감소하였다. 특히 carbonic maceration은 총산이 0.42 g/100 mL로 산도 감소에 효과적인 방법임을 확인할 수 있었다. 이는 HPLC를 이용하여 측정한 유기산 함량에서도 알 수 있었다. Control의 tartaric acid가 2,928 ppm인 반면 precipitation은 2,346 ppm으로 precipitation으로 인해 tartaric acid가 감소했음을 확인할 수 있었다. Control의 malic acid는 2,421 ppm, lactic acid는 486 ppm이었으나 MLF의 경우는 malic acid가 828 ppm으로 감소했고, lactic acid는 2,394 ppm으로 증가한 것을 확인할 수 있었다. 그리고 carbonic maceration은 malic acid가 993 ppm으로 눈에 띄게 감소하였고, cold fermentation은 유기산 함량이 전체적으로 감소한 것을 확인할 수 있었다. 산도가 감소한 포도주의 품질을 평가하기 위해 총페놀 함량, hue, 색도, 관능검사를 실시한 결과 산도 감소 효과가 우수한 precipitation과 carbonic maceration 방법으로 제조한 포도주가 품질 평가에서도 우수하게 나타났다. 이로써 본 연구에서는 carbonic maceration과 precipitation이 Campbell Early 포도주에 적합한 감산 방법이며, 제조한 포도주도 선명하고 진한 붉은색을 가지며, 포도향이 풍부하고, 신맛이 강하지 않음을 확인할 수 있었다.

The problem of incomplet state feedback began to appear late in60's and early in 70's. This was motivated by inability to measure all the states of the system in practice. This survey paper traces the early developments in the subject through to the most recent achievement of gain-determining, pole-assignment, stabilization, and low sensitivity system design with output feedback.

Purpose: A rib fracture secondary to blunt thoracic trauma continues to be an important injury with significant complications. Unfortunately, there are no definite treatment guidelines for severe multiple rib fractures. The purpose of this study was to evaluate the result of early operative stabilization and to find the risk factors of surgical fixation in patients with bilateral multiple rib fractures or flail segments. Methods: From December 2005 to December 2008, the medical records of all patients who underwent operative stabilization of ribs for severe multiple rib fractures were reviewed. We investigated patients' demographics, preoperative comorbidities, underlying lung disease, chest trauma, other associated injuries, number of surgical rib fixation, combined operations, perioperative ventilator support, and postoperative complications to find the factors affecting the mortality after surgical treatment. Results: The mean age of the 96 patients who underwent surgical stabilization for bilateral multiple rib fractures or flail segments was 56.7 years (range: 22 to 82 years), and the male-to-female ratio was 3.6:1. Among the 96 patients, 16 patients (16.7%) underwent reoperation under general or epidural anesthesia due to remaining fracture with severe displacement. The surgical mortality of severe multiple rib fractures was 8.3% (8/96), 7 of those 8 patients (87.5%) dying from acute respiratory distress syndrome or sepsis. And the other one patient expired from acute myocardial infarction. The risk factors affecting mortality were liver cirrhosis, chronic obstructive pulmonary disease, concomitant severe head or abdominal injuries, perioperative ventilator care, postoperative bleeding or pneumonia, and tracheostomy. However, age, number of fractured ribs, lung parenchymal injury, pulmonary contusion and combined operations were not significantly related to mortality. Conclusion: In the present study, surgical fixation of ribs could be carried out as a first-line therapeutic option for bilateral rib fractures or flail segments without significant complications if the risk factors associated with mortality were carefully considered. Furthermore, with a view of restoring pulmonary function, as well as chest wall configuration, early operative stabilization of the ribs is more helpful than conventional treatment for patients with severe multiple rib fractures.

The cement-based system among S/S(Solidification/Stabilization) is widely used to treat hazardous wastes. In this study, tannery sludge was solidified to evaluate the stabilization effects of using admixtures in the cement-based S/S. Fly ash as substitute also used to increase the strength of the S/S of hazardous waste. The compressive strength measurement and leaching experiment of chromium metal of solidified mortar were carried out to compare and evaluate the physical and chemical characteristics of solidified hazardous waste sludge. From the result of this study, there was increased of compressive strength by using AEW-3(early-hardening AE water reducing agent), and leaching concentration of chromium became low enough to satisfy the regulatory criteria. The successful solidification for the organic contaminant and heavy metal in hazardous waste should enable to treat by cement-based system using early-hardening AE water reducing admixture and fly ash as substituted cement.
