  • This study examined the consciousness of husbands and wives on babies' cries and its factors which have impacts on their emotional perceptions. For this study, infants' cries were recorded with the participation of 136 pregnant women and 76 husbands, and they conducted self-evaluations regarding their emotional perceptions and personal characteristics. The stimulus used to exhibit the cries of infants were from eighteen recorded cry sample under three situations (hunger, pain, and mother's absence) with six healthy infants (three male and three female) who are over six months. Also, this study dealt with the relationship between emotional assessment and the personal characteristics of mothers and fathers. As a result, the experience of child-rearing has a positive influence on the emotional cry perceptions of husbands and wives, and there was no sex difference in their emotional cry perceptions. A change of recognition, "being parents," has impacts on emotional cry perceptions, but the major factors increasing these impacts depend on the physiological changes of pregnant women and their personal characteristics.

  • The efficiency of live Peer-to-Peer (P2P) streaming protocols depends on the appropriateness and the management abilities of their underlying overlay multicast. While a tree overlay structure confines transmission delays efficiently by maintaining deterministic delivery paths, an overlay mesh structure provides adequate resiliency to peers dynamics and easy maintenance. On the other hand, content freshness, playback fluidity and streaming continuity are still challenging issues that require viable solutions. In this paper, we propose a Hybrid Live P2P Streaming Protocol (HLPSP) based on a hybrid overlay multicast that integrates the efficiency of both the tree and mesh structures. Extensive simulations using OMNET++ are conducted to investigate the efficiency of HLPSP in terms of relevant performance metrics, and position HLPSP with respect to DenaCast the enhanced version of the well-known CoolStreaming protocol. Simulation results show that HLPSP outperforms DenaCast in terms of startup delay, end-to-end delay, play-back delay and data loss.
