Recently, ubiquitous computing and sensor networks are making a rapid development. These technology can enable a new way of biomedical signal processing and healthcare. that is, they can improve care giving by a more flexible acquisition of relevant vital sign data, and by providing more convenience for patients. In this paper, we realize the biomedical sensor networks by applying IEEE 802.15.4/Zigbee networks to some various biomedical sensing unit. For address this, we developed minimized zigbee module and set-up procedure using PDA. The main advantages that we achieve are interference-free operation of different body sensor networks in the vicinity, as well as intuitive usage by the nontechnical personnel.

Purpose: This study examined the effect of music therapy on the pre-exam anxiety of gastroscopy clients. Method: The research period is from June 17 2002 to August 30 2002, and the subjects were 60 individuals, 30 for the experimental and 30 for the control group among adult clients. The data were analyzed by using the SPSS program. Result: The results of this study were as follows: The score of the experimental group was lower than the score of the control group for the situational anxiety (t=-12.56, p=0.000) and systolic blood pressure (t=-3.97, p=0.000) before the examination was supported. The vital sign was partially supported. There was no significant difference(t=-1.05, p=0.297) in the diastolic blood pressure (t=-1.05, p=0.297) and pulse rate(t=-1.30, p=0.199) before the examination of the experimental group and lower than the score of the control group. Conclusion: Music therapy could be useful in the nursing practice, and be utilized as a way of nursing intervention to reduce anxiety of the patients in specific clinical situations. Finally, it is recommended that further studies be conducted on this therapy by utilizing different musical selections.

With recent advances in wireless communication and low-power miniaturized biomedical sensor and semiconductor technologies, wireless body area networks (WBAN) has become an integral part of the disaster aid system. Wearable vital sign sensors can track patients' status and location, thus enhancing disaster rescue efficiency. In the past few years, most of the literatures in the area of disaster aid system based on WBAN have focused on issues concerning wireless sensor design, sensor miniaturization, energy efficiency and communication protocols. In this paper, we will give an overview of disaster aid, discuss about the types of network communication as well as outline related issues. We will emphasize on analyzing six key issues in employing the disaster aid system. Finally, we will also highlight some of the challenges that still need to be addressed in the future in order to help the disaster aid system be truly and widely accepted by the public.

We are report on three cases of typical clinical characterstics and treatment response in neuroleptic maligant syndrome(NMS), and reviewed the literatures of NMS. NMS was first recognized as a life-threatening complication of dopamine receptor antagonists, and defined as a catatonic-like states associated with fever, obtundation, muscle rigidity, and unstable vital sign in patients taking neuroleptic agents. Concepts of NMS have changed because medications other than classic neuroleptic drugs have been implicated as triggering agents and syndromes identical to NMS have been observed in other conditions. The important neurochemical features are probably functional dopamine deficiency and ensuing hyperactivity of excitatory amino acid neurotransmission in the basal ganglia and hypothalamus. Recognition of NMS and early discontinuation of neuroleptics are the most important step in its management. Supportive care includes management of hyperthermia and fluid replacement. Controversial therapeutic measures include the application of dopamine receptor agonists, excitatory amino acid antagonists, or dantrolene. Psychiatric patients with a history on NMS and psychotic relapse necessitating antipsycotics do not commonly redevelop NMS.

In this paper, an efficient signal interference control technique to improve the convergence speed of LMS algorithm is introduced. The convergence characteristics of the proposed algorithm,whose coefficients are multiply adapted in a symbol time period by recycling the received data,are analyzed to prove theoretically the improvement of convergence speed. According as thestep-size parameter ${\mu}$ is increased, the rate of convergence of the algorithm is controlled. Increasing the eigenvalue spread has the effect of controlling down the rate of convergence of the adaptive equalizer and also increasing the steady-state value of the average squared error and also demonstrate the superiority of signal interference control to the filter algorithm increasing convergence speed by (B+1) times due to the data-recycling LMS technique.
