using the cloud technology with Smart Protect Network (SPN) to do file virus scanning. The overwhelming increase of population will lead to an increase network traffic usage. In most products, local cache mechanism is implemented for the purpose of reducing the network traffics. However, the database designed to store cache is limited, lot of times, cache will get purged when there are lots of queries sent and replaced by other newest queries. It is not an efficient by using traditional methodology to build or forming cache. In order to reduce the network traffic usage, the paper propose a solution, which utilize data mining technique with clustering concept, by gathering the current feedback data we have from our SPN, we are able to form these data in groups with similarity, and by deploying these data to client side, to achieve the reduction of traffic usage. In prototyping, this design for military communications can really reduce network traffic more than 20%. And the speed of file scanning time can faster more than 12%.

This study is based on RFID technology to detect the locations of medical care personnel and patient who move around indoors; meanwhile, wearable and mobile physiological signal detection suite technique is associated to monitor the physiological status of the patient at any time. Through the positioning message of RFID, the computer system can assign medical care personnel that is nearest to the patient at emergency accident to perform medical care. Furthermore, through the use of wireless mobile device, it can be ensure that medical care personnel can obtain any emergency message of the patient at any time. Through integration of three techniques such as RFID technique, physiological signal detection suite technique and wireless mobile device, a set of emergency medical care system structure is designed in this study. Meanwhile, based on this system structure, a prototype system is developed to verify the feasibility of this system structure. Through the emergency medical care system developed in this study, no matter when and where emergency accident occurs, medical care personnel can reach the patient at the emergency accident site in the shortest time to reduce the possibility of delayed medical care.

Enterprises are increasingly using big data analytics and intelligence to solve business processes between original equipment manufacturers (OEMs) and original design manufacturers (ODMs) to increase the competitiveness and improve the efficiency of solutions. This research applies a cloud computing-based enterprise resource planning (ERP) system and OEM/ODM system to business to business (B2B) e-commerce. The integration of smart ERP system with B2B e-commerce can achieve the expected benefits of both. It reduces cost and improves the work efficiency, thereby improving the competitiveness of enterprises. In comparison to other traditional methods, the proposed system can make business management more efficient, promote the optimisation of cost structure, enhance the accuracy of sales orders, and improve the response time. It can also make the use of resources more reasonable.

The research combines two heuristic algorithms, COMSOAL and Priority rule-based algorithm, to design a production scheduling algorithm. Meanwhile it refers to dispatching rule and wafer start rule. Also base on the requirements and characters of wafer foundry companies, it designs proper capacity constraint model and wafer start rule to construct production planning system. Using simple, fast and flexible methods to generate reasonable and feasible production plans. The results of the research can give the wafer foundry companies several contributions. First, it shortens the execution time of generating a production plan. It improves the flexibility and efficiency of production planning. Second, the resolution of production plan is raised from the summary of manufacturing process and product type to full product name of order and demand allocation. It improves the resolution and accuracy of information analysis. Third, the planning period of wafer start plan is improved as well. Last, the frequency of production planning operation is improved from once a fortnight to once a week.
