The goal of Medical multimedia server is to develop computer hardware and software which would enable electronic access, storage, transmission, and display of patient data and images. Since the current network only provides so called "best-effort" services, it is impossible to satisfy QoS guarantee that is required for real time application services for emergency room, operating room etc. Accordingly, world-wide research is being made for a variety of services to provide QoS. he goal of DiffServ is to offer scalable differentiated service in Internet which are made possible by traffic classification and conditioning only performed at an edge(or a boundary) node. In case DiffServ was deployed in the Medical multimedia network, it is difficult to estimate how the QoS mechanism would affect totally the network performance. Therefore, we need to verify by simulation the design of algorithm which provide a variety of differentiated services. In QoS for Medical multimedia network, a simulator is designed and implemented using OPNET to investigate the performance of DiffServ QoS support mechanism. The developed DiffServ simulator may generate packets according to random, and bursty traffic models in order to incorporate diverse traffic conditions in the Medical multimedia network environment. Based on our simulation results, we confirmed that service differentiation is possible by using the EF(Expedited Forwarding) class in DiffServ networks.

The purpose of this paper is to implement a multiple bio-signal central monitoring system based on textile fabrics flexible platform which can obtain and monitor bio signals(heart rate, body temperature, electrocardiography, electromyogram) of workers in special working environments and additional situational information (3-axis acceleration, temperature, humidity, illumination, surrounding image). This system can prevent various accidents that may occur in the remote work environment and provide fast and efficient response by detecting workers' situations in real-time. For it, the textile fabrics flexible platform was made as innerwear or outerwear so that it does not interfere with workers' performance while collecting bio-signal and situational information, and obtained information is sent to the central monitoring system through wireless communication. The central monitoring system is based on wireless medical telemetry service of WMTS (Wireless Medical Telemetry Service); can monitor from 2 to 32 people simultaneously; and was designed so that it can be expanded. Also, in this study, to verify performance of the WMTS communication model, packet transmission rates were compared according to the distance.

Purpose: The aim of this study was to compare the "Physical Therapist and Occupational Therapist Act" of Japan and the "Medical Technician's. Etc. Act" of Korea in order to establish the grounds for improvement of effective law-making. Methods: We obtained the "Medical Technician's. Etc. Act" from the Korean Ministry of Government Legislation and the "Physical Therapist and Occupational Therapist Act" from the Japanese Ministry of Health, Labor and Welfare. It was translated from an association by related Japanese and experts. Results: The laws consisted of acts, enforcement ordinances, and enforcement regulations in both Korea and Japan. In the Korean case, eight occupations were defined in one law including six types of medical technicians, as well as medical recorders and opticians. The "Physical Therapist and Occupational Therapist Act" in Japan is composed of 6 chapters and 22 articles, while the Korean Act consists of 33 articles without chapters. Among them, 11 articles covered the establishment and management of dental laboratories and eyeglass shops, and only 22 articles were related to physical therapists and occupational therapists. Conclusion: Independent laws should be established for each type of medical technician. They must be comparable to Japanese laws on physical therapists and occupational therapists as well as clinical pathologists, dental hygienists, dental technicians, radiologic technologists, medical recorders, and opticians.
