一個結合容錯機制的雲端儲存平臺

A Cloud Storage Platform Based on Fault-Tolerant Mechanism

組織變革一直是組織突破困境的方法，當企業面臨到業績滯足不前或是營利衰退的困境，組織變革時常被拿來運用，加上組織變革配合組織創新更能促進組織變革的成效，因此組織變革常伴隨著組織創新，然而不管是組織變革亦或是組織創新皆需要成員的配合才能呈現其效果，因此成員的理解與支持相當重要，成員了解企業的用意與用心反而會對企業產生信賴，最後發自內心的協助企業提升工作績效，共同突破窘境。所以，綜合以上研究背景與動機之描述，本研究認為組織創新會中介影響組織變革認知與工作績效之關係，而組織承諾也會中介影響組織變革認知與工作績效之關係。本研究發現，組織變革對於組織創新、組織承諾與工作績效皆具有正向影響，同時，組織承諾對於組織創新與工作績效具有正向影響，最後組織承諾對組織變革認知與工作績效有完全中介的效果。組織變革是目前各產業積極進行的方向，無論是極力突破現況或是為了在激烈的市場裡爭奪一席之地，又或是維持自身競爭力，由於在組織變革的同時常常伴隨組織創新，以創新思維讓企業有別於以往的模式進行變革，同時，在組織極力轉變與成長的氛圍增加員工對企業的信心，最終員工相信企業的信念後也會相對付出其心力為企業帶來工作績效。 Organizational change always be the way to breach the bottleneck when the enterprise face to dilemma such as stagnantly performance and profit decline. However organizational change with organization innovative have synergy affect that is the reason organization innovative often come with organizational change, but no matter organizational change or organization innovative all need members support. It is important about understanding and backup from members also when members recognize intention of the enterprise they would feel trust and responsibility to this responsibility. Then members work more hard in return for enterprise and help the enterprise to get high level of job performance. This work supposes organization innovative is mediator to affect the relationship between organizational change perception and job performance also organizational commitment is mediator to affect the relationship between organizational change perception and job performance too. Based on the result, this work discovers organizational change perception positive influence organization innovative, organizational commitment and job performance, meanwhile organizational commitment positive influence organization innovative and job performance. At last organizational commitment is organizational commitment mediator to the relationship between organizational change perception and job performance. In order to breaking through the current situation, holding more market share or keeping competition, therefore organizational change is the goal that all industries hardly achieve to. Because organizational change always follows organization innovative happened and innovative thinking makes organizational change in the different way. Stuffs have confidence when the industry pays effort to make organization change and grow up, in the end stuffs believe the faith of company would work hard for job performance raise up.

This study proposed a framework which is composed of a modified column-based data model and a backup mechanism by using network coding to enhance the retrieval speed and the fault tolerance of cloud storage for the integrity and reusability of user data in cloud storage. In experiments, the modified column-based data model used less 41% retrieval time than the traditional column-based data model when the space utilization rate of the data matrix was less than 50%. When the fault tolerance requirements were the same, the proposed backup mechanism saved 33% and 50% more spaces than the traditional backup mechanism according to different column bases and allowable machine faults respectively.
