We have previously observed that HIV-1 replication is suppressed in uninflamed lung and increased during tuberculosis. In vitro THP-1 cell–derived macrophages inhibited HIV-1 repli-cation after infection with Mycobacterium tuberculosis. Suppression of HIV-1 replication was associated with inhibition of the HIV-1 long terminal repeat (LTR) and induction of(More)
The Internet is being widely used these days and many users are required to manage their network environments, because damages caused by worms, which spread using security holes of software, are also increasing rapidly. One of the effective means of detecting the damages caused by the worms in early stage is to analyze the network communication logs stored(More)
Recently researches concerned with various applications based on collaborative virtual environment (CVE), such as virtual society, virtual shopping mall, virtual museum etc., methods to realize cooperative works by users in 3D virtual space and scalability issues of the VR space to support a number of users have been investigated. However, as the number of(More)
Recently, many applications of VR called collaborative virtual environment (CVE) have been proposed and their cooperation methods by users and scalability issues to support a number of users have been investigated. However, by using conventional client/server model, the usability of co-operative works by users degreases and scalability in CVE cannot be(More)

Recently many communication systems based on three dimensional spaces are proposed. In those systems, in order to support many users in the same space, QoS control function based on the distance among the avatars is mainly applied. For this reason, the computing and network resources in the communication systems are wasted. In this paper, we suggest a new(More)
