The advancement of computer network technology, coupled with the growing prevalence of Internet, is promoting ubiquitous computing, also called next-generation computing paradigm, as an important study field that many researches are joining and undergoing. In this paper, as the support technology for creating ubiquitous computer environment, we design the SSDLbased on XMLwhich is used for sending and receiving data by USN application service in a standardized form. A ref model, with no regard to different platforms or implementation languages, is proposed in our research on the basis of web service so that most of unspecified users could apply the standardized protocol designed for sensor data to real sensor data in various application environments based on the designed language. Therefore, through this research we can take advantage of acquisition of USN-based technology and technology draft related to application service.

An essential step in evaluating and comparing the performance of two passive radiation dosimeter types, thermosluminescent (TLD) and optically stimulated luminescence (OSL), used by workers in environments with ionizing radiation for individual radiological monitoring and control of external exposure at various times (cumulative dose for 1 month), is to compare the measured dose accuracy, energy response, and coefficient of variation. In fact this performance study consists in determining the accuracy of both R(10) and R(0.07) which are considered as the ratios of the measured dose (Hp(10) or Hp(0.07)) to the delivered dose (Hp(10) or Hp(0.07)) for each photon energy. The validity of the results of this test is based on the acceptance limits of the ICRP and the international standard IEC-62387. The relative energy response used is normalized to the ¹³⁷Cs 662 keV energy to find which energy response is closest to the ideal case, and the coefficient of variation that allows to determine the statistical fluctuation of the Hp(10) and Hp(0.07) doses. The results of the accuracy test for the OSL and TLD dosimeters are acceptable because they fall within the ICRP limits. For the energy response, the OSL performs better than the TLD for Hp(10) and Hp(0.07), and for the coefficient of variation, the OSL satisfies the requirements of ISO 62387 for both Hp(10) and Hp(0.07), while the TLD satisfies these requirements only for the measurement of Hp (0.07).

The world is rapidly evolving in the future society is based on intelligence. In such circumstances, USN(Ubiquitous Sensor Network) to implement the future ubiquitous(Ubiquitous) society have been highlighted as a key infrastructure. For realization of Ubiquitous computing(Ubiquitous Computing), The data recognized from each sensors must be collected on real-time and transferred to applied service so that they may be used as data for providing service to users. USN sensor data on the use for using a numerous sensor data provision service, service provider can publish its service in standardized registry for users to search and use the service registry. However, in previous studies using Web services standards WS-Eventing, and UDDI(Universal Description, Discovery, and Integration) as USR(USN Service Registry) for USN Application Service is unnecessary or insufficient. In this paper, data from sensors that provide information to service providers register their services and use the information for service users to explore and views on the registry of the system was designed and implemented.
