  • Mutimedia conference technology provides conference service as well as data service via Internet. Many standards and related applications were developed based on H.323 protocol. but H.323 protocol more complex than SIP. so IETF have developed standard that related conference control based on SIP. In this paper, we design conference event package for conference system based on SIP protocol.

  • In this paper, fully embedded high Dk BTO MIM capacitors have been developed into a multi-layered organic package substrate for low cost RF SOP (System on Package) applications. These embedded MIM capacitors were designed and simulated by using CST 3D EM simulators for finding out optimal geometries and verifying their applicability. The embedded MIM capacitor with a size of $550\;{\times}\;550\;um^2$ has a capacitance of 5.3pF and quality factor of 43 at 1.5 GHz, respectively. The measured performance characteristics were well matched with 3D EM simulated ones. Equivalent circuit parameters of the embedded capacitors were extracted for making a design library.

  • This paper presents how to create a 3D map and solve problems related to generating a global path planning for navigation. Map creation and localization were performed using the RTAB-Map package to create a 3D map of the environment. In addition, when the target point is within the obstacle space, the problem of not generating a global path was solved using the asr_navfn package. The performance of the proposed system is validated through experiments with a wheelchair-type robot.

  • This study was conducted to examine utilization patterns and determinants of oriental medical services. Data were collected from 545 residents in Taegu city The results of this study are summarized as follows 1) 37.8% of subjects used oriental medical services in the past year. Especially, the female, the ages of 50 and 60 over, the single. low-educated. high-income class, white-collar class, medical insured tended to use more oriental medical services than another groups. 2) 46.7% of users of oriental medical services reported that number of visits in the past year was 2 - 5 times 37 1% of them was 1 times, and 4.5% over 10 times. 3) According to the reasons to choose the oriental medical facilities, most was 'on their own judgement'(48.8%) and 'by the advice of relatives and friends'(42.0%) Regarding to the objectives of using oriental medicine, 68.3% was 'treatment', 31.7% 'health counselling and promotion'. And among diseases of users, diseases of musculo-skeletal system was the highest(54.5%). 4) 57.9% of oriental medical services users had experience of utilizing western medicine on the same diseases. Among peoples with experiencing western medicine on the same diseases. 54.4% received oriental medical services 'in addition to western medicine', 45.6%'in place of western medicine 'And 41.2% of using both services reported that they had difficulty in deciding to choose the type of services -oriental medical services or western medicine-for their diseases. 37.3% of them answered that 'providing relevant information' was the most desirable measure to solve this problem, 27.3% 'establishment of effective referral system between oriental and western medical facilities '23.6% 'cooperative medical treatment systems in the same facilities', 11.8%'integration of oriental medicine into western medicine 5) According to the satisfaction level with each items of oriental medical services, the respondents had positive views on efficacy, kindness, and side-effects. They, however, had negative view on the cost of oriental medical services. 6) In regarding to the priority of improvement of oriental medical system,'expansion of insurance benefit package 'ranked first. 'expansion of insurance benefit Package 'ranked second, 'improvement of scientific methods and diagnostic technique 'third, and 'safety of herbal medicine' fourth in order. 7) The significant factors influencing the utilization of oriental medical services were kindness of oriental medical practitioners, efficacy , travel time, age To be brief, utilization rate of oriental medical services in urban area generally tends to be high. There, however, have been various barriers to limit oriental medical services, such as incomplete benefit package of oriental medical insurance and lack of coordination and referral system between oriental and western medical services, lack of scientific diagnostic procedures, high price etc . For the development of oriental medical services, Much attention to remove these limiting factors should be placed. In addition, kindness of oriental medical practitioners , which is expected to be more important factor in the consumer - focused health care environment than ever, should be kept high consistently. Since this study was conducted for specific residents of an urban city. further research including more sampling in different urban areas should be required to generalize the results of the study.

  • In an effort to examine the Regional Atmospheric Modeling System (RAMS ver. 4.3) to the initial meteorological input data, detailed observational data of NOAA satellite SST (Sea Surface Temperature) was employed. The NOAA satellite SST which is currently provided daily as a seven-day mean value with resolution of 0.1 $^{\circ}$ grid spacing was used instead of the climatologically derived monthly mean SST using in RAMS. In addition, the RAMS SST data must be changed new one because it was constructed in 1993. For more realistic initial meteorological fields, the NOAA satellite SST was incorporated into the RAMS-preprocess package named ISentropic Analysis package (ISAN). When the NOAA SST data was imposed to the initial condition of prognostic RAMS model, the resultant performance of near surface atmospheric fields was discussed and compared with that of default option of SST. We got the good results that the new SST data was made in a standard RAMS format and showed the detailed variation of SST. As the modeling grid became smaller, the SST differences of the NOAA SST run and the RAMS SST43 (default) run in diurnal variation were very minor but this research can apply to further study for the realistic SST situation and the development in predicting regional atmospheric field which imply the regional circulation due to differential surface heating between sea and land or climatological phenomenon.

  • In this paper, we have studied a new method in which multimedia message can be processed effectively in SIP(Session Initiation Protocol)-based Instant Messaging service. Total system is composed of multimedia message server, presence server and user system. To provide effectively message informations such as number of messages stored in the multimedia message server, waiting status and message types to users, we have proposed a new method which can be a substitute for message waiting indication event package. In our proposed method, when changes of messages status informations occur, these informations are sent to the presence server, and can be transferred as a separate tag within notification message. The presence server processes subscription requests and notifications, and efficiency can be improved as it provides both message status informations and several communication status informations such as on-line status to service users. Partial publication is used in our system to improve data transfer efficiency more between user system and the presence server. The performance of our proposed model is evaluated by experiments measuring multimedia message transfer speed and server processing time.

  • In this study, radar data integrating and processing systems were designed for the data processing of various information from many kinds of radar in a single data processing system. The characteristics of the data integrating system were analyzed by the system simulation with the queueing theory. The designed data integrating systems can be divided into a centralized and a distributed type. In the system structure, we used UNIX message que as the real time processor and the queueing theory for the performance evaluation of the information flow in the systems. For the analysis of the performance of inforamtion flow in both models, queueing theory was applied to and implemented with the simulation package, OPNET system and C language. From the simulation result we could understand the system factors which effect the system performance and characteristics on the data processing.
