This paper is focused on the medical CRM system design for a hospital custom management. CRM systems provides information and seminars to whom are necessity. For this, priority retrieval and similarity retrieval are able to be in the personnel order and the regional. The customer receives the message which sends out from the hospital, The hospital manages the message which reveals a participation intention in the seminar at real-time. The hospital grasps the participation degree of the seminar where the customer will participate and manages the patients who participate to the seminar actively, and when the next seminar will be hold, we designed the system able to provide the service as early as possible.

Currently digital TRS is providing the voice-oriented service based on stat-tree topology of 2.5G. As result of that, it has alimitation to accept the wide band multimedia services. Therefore, this paper designed the mesh topology based on packet networkand proposed the algorism of dynamic path establishment based on priority. In korea case, we confirmed that hop numbers priority base is more reasonable than distance priority base. And counted the trunk traffic including redundancy traffic to prevent the bottlenect situation and trouble. Also analysed the bandwidth between network management centers of backbone and access.

The objective of this study was to set priority for future core technologies in agricultural and environmental science using analytic hierarchy process(AHP). Forty-six technologies were derived by specialist meetings. Evaluation criteria, for setting the priority were decided as 'technology', 'marketability', and 'public'. Eighteen specialists in agricultural and environmental science answered to the questionnaire for AHP. As the results, 'technology' was decided as the most important evaluation criterion. The 'Feasibility' in 'technology' criterion, 'Market Growth' in 'marketability' criterion, and 'Impact to other industry' in 'public' criterion were decided as sub-criteria in each criterion. The most important technology was 'Risk assessment of toxic heavy metals and establishment of accreditation criteria for environmentally friendly agricultural products.

We propose a new space priority mechanism, and analyze its performance in a single Constant Bit Rate (CBR) server. The arrival process is derived from the superposition of two types of traffics, each in turn results from the superposition of homogeneous ON-OFF sources that can be approximated by means of a two-state Markov Modulated Poisson Process (MMPP). The buffer mechanism enables the Asynchronous Transfer Mode (ATM) layer to adapt the quality of the cell transfer to the Quality of Service (QoS) requirements and to improve the utilization of network resources. This is achieved by "Selective-Delaying and Pushing-ln"(SDPI) cells according to the class they belong to. The scheme is applicable to schedule delay-tolerant non-real time traffic and delay-sensitive real time traffic. Analytical expressions for various performance parameters and numerical results are obtained. Simulation results in term of cell loss probability conform with our numerical analysis.

Recently, in the context of increased interest for marine tourism, Jeju region of South Korea has attractive waterfront space and also has potential requirements for development. The objective of this paper was to analyze the priority for resource development of waterfront in Jeju region. In order to calculate the importance of factors related to the development of waterfront in Jeju area, this study conducted exploratory factor analysis to extract the factors and established the AHP model based on the factors name focusing on a total of 198 tourists. In this study, in accordance with the procedures of AHP analysis, pairwise comparisons were conducted focusing on a total of 15 experts. Especially, difference test between groups (academics and bureaucratic) was conducted. In the 1st criterion for evaluation, 'exploring experience' factor is most important thing and 'facilities & infrastructure' factors were in the following order. In the secondary criterion, AHP analysis showed that experience facilities, environmental management, and absence of residents consciousness were the important factors. In the future time, the results of this research can be utilized as basic data in the aspects of tourism development in Jeju waterfront region.

Auditors' subjective opinions m audit activities weaken reliability in audit judgments. This paper suggests fixed quantity models through requirement priority for improving objective evaluation and priorities of requirements in information system audit. The value of requirements was evaluated based on customers' requirements with a premise that they are not in the same level. Furthermore, the audit objective judgments were enhanced to enable fixed quantity of subjective audit by subdividing detailed evaluation index of requirement priority standards into importance of service and function on orderers' perspective, and sectioning cost and schedule on contractors' perspective.

In this paper, we addressed the problem of upstream bandwidth in EPONs. We presented a wavelength division EPON supporting QoS in the differentiated services framework. It was shown that the bandwidth allocation by priority scheduling, under our assumptions for traffic behavior, will result in an unexpected behavior for high priority class and we suggested the use of weighted priority scheduling to alleviate this problem. Our wavelength division EPON supporting QoS allocates effectively and fairly bandwidths and wavelengths between ONUs in the differentiated services framework. Moreover, we showed better performance in terms of average and maximum end-to-end delay, as well as network throughput, utilization compared with some other algorithms. We used simulation experiments to study the performance and validate the effectiveness of the proposed network and algorithm.

According to spreading of smart devices and development of communication technology, the security issues come to the fore in the modern factory. Especially, the smart facpry should be considered the risk management plan how to identify and evaluate, control the risks. In this paper, we suggest the minimum security requirements applying SFRPN(Smart Factory Risk Priority Number) model to domestic smart factory on the basis of the results inspecting factories.

The study was focused on setting priority for future core technologies in rural development and resources using AHP. The technologies were derived by Delphi method. Evaluation criteria for the priority setting were decided as 'technology', 'market oriented', and 'public concerns' by council. The future core technologies were divided as four groups by importance and R&D level. Technologies in upper two groups were considered in the study. Group I had high importance and high R&D level. Group II had high importance and lower R&D level. Questionnaires were given to 9 specialists in agricultural resources. As the results, 'public concerns' was decided as a most important evaluation criterion. The most important technologies are "technology developing for animal feces and urine treatment, and restoration it to farm land" in group I, and "technology developing for agricultural by-products as energy source" in group II.

This paper presents the development of three types of network performance manager for IEEE 802.4 token bus networks that are a part of Manufacturing Automation Protocol(MAP). The performance managers attempt to keep the average data latency below a certain level specified for each priority class. All of the three performance managers are based on a set of fuzzy rules incorporating the knowledge on the relationship between data latency and parameters of the priority mechanism. These Fuzzy Network Performance Managers(FNPMs) have been evaluated via discrete event simulation to demonstrate their efficacy.
