The development of modern information technology has promoted the construction of digital learning environment which represented as digital learning harbor, in this situation, teachers' learning community became an effective shortcut for teachers' professional development. This paper comes from digital learning harbor project, analyses and defines the connotations of teachers' learning community in the digital learning environment, and makes an intensive study of the effective support from digital learning harbor to teachers' learning community.

Due to increasing the technologies security systems are very popular in many *** security of information can be achieved by using encryption and *** cryptography,encrypted data is transmitted after transforming the other form instead of the original data. Contrast cryptography,information hiding process can be extended for protecting from the interesting of any attacker. This paper proposes the enhance security system by combining these two *** this system,the encrypted message is embedded in a BMP image *** proposed system,three LSB steganographic techniques have been implemented and *** proposed system intends for data confidentiality,data authentication and data *** system not only enhances the security of data but also becomes more powerful *** system intends to support effective ways for protecting *** primary goal of our system is to enhance the security of data and then to compare three steganographic *** we will use the optimized method for *** this paper,we just present three steganographic *** this system,data is encrypted with RC4 encryption algorithm and then embedded the encrypted text in the BMP image file using three steganogrpaphic methods.
This paper mainly talks about the physical model of rubber/PVDF semi-active piezoelectric composite level-based system, and the calculation method of sound energy loss of the system is studied too. The principle of im...
