Effect of listening to music among patients with dental anxiety.

Listening to music during dental treatment is widely accepted as a relaxation method. However, its effects are unclear on the psychological and vital parameters. Patients who came to the Government Hospital of 18 - 60 years old, medically fit and indicated for dental extraction and exhibiting dental anxiety were included in the study. Music was not played in the control group (n=100) whereas in the experimental group (n=100), music was played according to patients' preference under the genre western, classical, or popular. Blood pressure, Body temperature, Pulse rate, Oxygen saturation and Respiratory rate were recorded. Results showed no statistical difference between the control and experimental group except the respiratory rate which increased statistically in both control and experimental group. Thus, the current study reveals that the effect of music over an invasive procedure like extraction that has been perceived as painful treatment for a long time has little effect on adult patients.

Modeling and Simulation of a Novel Relay Node Based Secure Routing Protocol Using Multiple Mobile Sink for Wireless Sensor Networks.

Data gathering and optimal path selection for wireless sensor networks (WSN) using existing protocols result in collision. Increase in collision further increases the possibility of packet drop. Thus there is a necessity to eliminate collision during data aggregation. Increasing the efficiency is the need of the hour with maximum security. This paper is an effort to come up with a reliable and energy efficient WSN routing and secure protocol with minimum delay. This technique is named as relay node based secure routing protocol for multiple mobile sink (RSRPMS). This protocol finds the rendezvous point for optimal transmission of data using a "splitting tree" technique in tree-shaped network topology and then to determine all the subsequent positions of a sink the "Biased Random Walk" model is used. In case of an event, the sink gathers the data from all sources, when they are in the sensing range of rendezvous point. Otherwise relay node is selected from its neighbor to transfer packets from rendezvous point to sink. A symmetric key cryptography is used for secure transmission. The proposed relay node based secure routing protocol for multiple mobile sink (RSRPMS) is experimented and simulation results are compared with Intelligent Agent-Based Routing (IAR) protocol to prove that there is increase in the network lifetime compared with other routing protocols.
