Management of biosignal data in mobile devices causes many problems in real-time transmission of large volume of multimedia data or storage devices. Therefore, this research paper intends to suggest an m-Health system, a clinical data processing system using mobile in order to provide quick medical service. This system deployed health system on IP network, compounded outputs from many bio sensing in remote sites and performed integrated data processing electronically on various bio sensors. The m-health system measures and monitors various biosignals and sends them to data servers of remote hospitals. It is an Android-based mobile application which patients and their family and medical staff can use anywhere anytime. Medical staff access patient data from hospital data servers and provide feedback on medical diagnosis and prescription to patients or users. Video stream for patient monitoring uses a scalable transcoding technique to decides data size appropriate for network traffic and sends video stream, remarkably reducing loads of mobile systems and networks.

It is important to improve TCP performance in Self-similar TCP network where signalling between the same end nodes through bidirectional traffic routes. In wireless link, the traffic limitation pattern occurred in two or more TCP connections is applied into MPEC video control as multi time-interval congestion control. For TCP update variable, we extend TCP and perform as function call, and we study a method of relating TCP with LTS module controlling with the information type that is overcoming the limit of feedback loop determined by RTT. For comparison, we measure the TCP throughput without LTS and verify the fairness by means of meta control. The improved TCP performance is shown by that the number of connections of traffic congestion control increases when RTT increases.

The purpose of this study was to develop psychological skill training program for actor with considering the ecological validity of social, cultural environment in Korean but also examine the effect of psychological skill training through psychological counseling and field study to decrease stage-anxiety. The experimental group were 2 actors, who were selected by purposive sampling. The psychological skill training program to decrease stage-anxiety for actor was composed of five stages, 12times and categorized as orientation, breathing regulation, progressive relaxation training, group counseling, heart rate bio-feedback training, self concentration, routine training, behavior therapy & self reinforcement, image training. The effects was examined on stage performance anxiety scale, psychological counseling and observation of experts. As the result of applying the psychological skill training to decrease stage-anxiety, cognitive state anxiety, somatic state anxiety were decreased. According to the result of counseling and observation, they were changed affirmative on self confrontation, harmony and rapport between actor and object. This result demonstrated the psychological skill training & counseling to decrease stage-anxiety for actor were effective.

Purpose: Recently well-developed anorectal function tests have revealed that there is an obvious pelvic floor dyssynergia (PFD) pattern in pediatric patients with constipation, as well as in adult's. The use of biofeedback therapy (BT) has been widely implemented in adult PFD patients; however, this approach has only rarely been considered for pediatric PFD patients. Therefore, we assessed the effectiveness of BT in children with PFD. Methods: We studied 70 children with PFD, who were referred to the department of pediatrics at the Asan Medical Center for the management of soiling or chronic constipation from September 2002 to February 2005. Diagnosis of PFD and assessment of the efficacy of BT for PFD treatment were carried out along with several ano-rectal function tests (cine-defecography, ano-rectal manometry, balloon expulsion test and intra-anal EMG); in addition, a questionnaire was administered. The BT based intra-anal EMG was performed. A follow-up telephone interview was performed more than 6 months later. Results: Most of the symptoms and results of the ano-rectal function tests were statistically improved after BT. In comparisons between the BT and control groups (BT refusal group due to poor compliance), the symptoms were statistically improved at follow-up. Therefore, for the shortterm improvement of symptoms, BT was better than conservative therapy alone. The negative feelings associated with ano-rectal function testing and BT were directly associated with failure or success of therapy. Conclusion: Pediatric patients with constipation or soiling that presented with an obvious PFD pattern showed that BT was a useful therapeutic tool for rapid improvement of symptoms.
