Using mobile device to access WLAN that use a Access Point to use mobile device to access WLAN that use a Access Point WEP key and authentication procedures that are needed. Most owners of the AccessPoint in the AccessPoint device proportioned to create a company by using the default WEP key since default key are know by unauthorized users, there is vulnerability outflow of personal information. In this treatise, automatic WEP key generation, in new hardware design in proposed. This can prevent personal information leakage.

The fundamental goal of the system tuning is to maintain the fast response time and to optimize the system performance at the same time. In this paper, WebLogic-based personal banking system and enterprise banking system are analyzed by the load-test tool that considers the predicted number of users from bank A and the transaction volume. The performance-analysis tool is run by the LoadRunner, in which the performance test and load test are efficiently performed. The estimation index shows the following in the system: at most 300 simultaneous users respond within four seconds; at most 650 simultaneous users respond within eight seconds; at most 800 users are limited under 80% of CPU usage. Furthermore, the host and delayed status of the response time of the system-related service are diagnosed. By suggesting the improved plan of the system management, the system will have the optimum performance in the future operation.

Anguillosporal dose-dependently inhibited phospholipase C (PLC)γ1 activity in A431 cells in response to epidermal growth factor (EGF). The compound also inhibited PLCβ1 activity in α-thrombin- stimulated CCL39 cells. In accordance with this, PLCγ1 and PLCβ1 activities were also decreased by anguillosporal in vitro. However, anguillosporal did not reduce the auto- phosphorylation of EGFR and the tyrosine phosphorylation of PLCγ1 in EGF-stimulated A431 cells. Also anguillosporal did not inhibit the tyrosine kinase activity of EGFR. From these results, it is suggested that anguillosporal is a specific inhibitor of phospholipase C.
