This study investigated the relation ship between the slope and shape of the acromion and the spur at the antero-inferior surface of the acromion no clarify the cause of subacromial impingement. This investigation was performed with 205 scapular dry bone specimens. The specimens of 107 males were used. Their ages ranged from 20 to 83 years with an average age of 56.5 years. The presence of acromial spurs was identified. All acromions were classified visually as type I (flat), type II (curved) or type II (hooked) as described by Bigliani et al. And the slope of the acromion was measured in all specimens.A spur at the antero-inferior surface was seen in 96 acromions (46.8%). And almost all spurs were located in the anterior one third of the acromion. In all specimens, fifty-six acromions (27.3%) were type I, one hundred and eight (52.7%) were type II and forty-one (20.0%) were type III. The type of acromion was not related to the presence or absence of a spur. The average slope of all acromions was 46±8°, that of acromions with spur was 44±7° and that of acromions without spur was 49±8°. There was a significant difference between the slope of the acromion with spur and acromions without spur. From this study it can be concluded that the type of acromion had no relation ship to subacromial impingement and the flattened slope of the acromion might be one cause of subacromial impingement.

Problem may arise when the drivers are unable to notice or late in noticing emergency vehicles due to the sealing nature of the vehicles, masking by the car audio system or car navigation operation, which poses a threat for common vehicles and emergency vehicles to collide at many crossing. Every minute, problem may arise at every crossing and it is dangerous to wait for the completion of the information infrastructure system, which requires suitable cost and time. Therefore, we propose a system for common vehicles, which detects emergency vehicles using microphone on-vehicle and produce warning information to the driver. In this research, our focus is for “Ambulance", “Fire Truck" and “Police Car". The siren for these vehicles is detected by means of a microphone on-vehicle. This project utilizes two microphones to in order to detect the direction in which incoming emergency vehicles are present. The system, which we propose, must be helpful to response quickly to emergency and rescue activities.

<Purpose> The purpose of this study was to investigate the strength of the glenoid labrum and capsule.<br><Materials and method> 15 shoulders of fresh cadavers were used for this study.6 of them were the right side and the rest of the 9 were the left side. Their ages ranged from fifty-five to eightyeight years. There were 6 males and 3 females. We determined the anterior, inferior and posterior portion of the labrum and capsule as the 3,6 and 9 o'clock position, respectively. The labrum and capsle were cut in 5mm width pieces. After fixing the glenoid, each respective piece of labrum and capsule was strained. We measured the applied force which detached the labrum from the glenoid.<br><Results> The 4 o'clock position was comparatively weaker than any other position, irrespective of the age or sex of the cadaver.<br><Conclusion> We conclude that the anterior-inferior portion of the glenoid is weaker than any other portion.

There are rarely few reports on the clavicular motion during elevation of the extremity. This is may due to the complicated shape of the clavicle and its three-dimensional movement. The purpose of this study is to analyze the movements of clavicle by using X-ray fluoroscope.The study was performed on a 21 years old female who had clavicular fracture a year ago and had fixation with plate and screws. She had no difference on both shoulder ROM when examined. In front of X-ray fluoroscope, she was asked to abduct her arm to full in 10 seconds, and the movements were recorded on videotape. From the location of plate and screws we analyzed the clavicular motion.The clavicle rotated clockwise in its long axis when viewing from the left sagittal plane. This movement increased constantly during the elevation of arm and reached 50 degrees at maximum abduction. In Frontal view, 25 degrees of upward movement was observed, where the majority of the movement was seen within 90 degrees of elevation.

We investigated the mechanism stabilising the glenohumeral joint that prevents anterior dislocation. We measured the strength of the glenoid labrum and capsule in fifteen shoulders of nine fresh cadavers. The glenoid labrum and capsule were cut in widths of 5mm then the glenoid fixed and the labrum and capsule strained. We measured the tension when the labrum detached from the glenoid or the capsule ruptured. Results showed that the anterior-inferior portion is weaker than the other portion.
