Communications network damage resulting from a large disaster causes difficulties in the ability to rapidly understand the current situation and thus make appropriate decisions towards mitigating problems,such as where to send and dispense emergency *** research outlined in this paper focuses on the rapid construction of a network after a disaster *** study suggests ZigBee and geographic information systems(GIS)technologies to resolve these problems and provide an effective communication *** experimental results of the ZigBee network system are presented,examples are provided of the mapping and analysis undertaken using GIS for the disaster-stricken area of Tsukuba City,Japan,and the communications node arrangements are determined for this *** results demonstrate the effectiveness of establishing such a communications system for supporting efforts to relieve disaster-damaged areas.

Objective: To investigate the morphological chan ges of the roof of the subacromial bursa (SAB) and its involvement extent after rotator cuff tear. Methods: In the experimental group,the roof of SAB was obtaine d from 30 cases of rotator cuff tear both at the tear site and a site 2.5 - 3.0 cm distal to the tear site during rotator cuff repair. In the control gr oup,the roof of SAB was obtained from the exposed site of recurrently dislocate d shoulder or fractured humeral shaft of 8 cases. The specimens were stained wit h hematoxylin and eosin and observed under a transmission electron microscope. T he cell number was quantitated through counting the blue-stained nucleus in SAB with a computer image analysis ***: The number of cells increased significantly in the roo f of SAB in the experimental group compared with that of the control group. Howe ver,no difference of the bursal reaction was found among the type of rotator cu ff tear,the bursa thickness and the presence of fluid in the bursa. The great m ajority of cells were type B cells observed under the transmission electron micr ***: The increase in cell number in the roof of SAB in the experimental group is a reactive increase rather than an inflammatory proces s and the involvement of SAB is not limited in extent. The change of the roof of SAB is a secondary reaction to the rotator cuff tear.

Ｃｏｄｍａｎ提出冈上肌离大结节止点１ｃｍ处为乏血管区，此区是造成肩袖撕裂的主要原因。ＮｅｅｒⅡ则提出９５％的肩袖撕裂是由肩峰下撞击引起。作者对３５例肩袖撕裂的病人进行了临床与手术的观察，发现肩袖撕裂的部位主要分布于冈上肌，占９７．１％。３５例中撞击征病人１０例。Ｃｏｄｍａｎ的乏血管区不仅存在于冈上肌，亦存在于肩袖其它肌腱，故乏血管区不是引起肩袖撕裂的主要原因。撞击征亦不是，只占全部撕裂总数的２８．６％。作者认为引起肩袖撕裂的内在因素包括肩袖肌腱的乏血管区和冈上肌的特殊位置和功能，外在因素包括肩关节反复应用，肩峰下撞击和不同程度的肩部外伤。
