  • Performance management of ATM network is urgently required because a different quality of service should be guaranteed on each connection. A lot of performance measurement data increase the burden on agent systems and on managment stations. In this paper, an effective OAM-based performance monitoring and faulty node identification technique is proposed. A proposed VP Selection Algorithm reduces management-related traffic and when the indication of hard or soft failure state is detected, failed node is identified by Fault Identification Rule.

  • This paper considers the TMN system for management of public ATM switching network which has the four-level hierarchical structure consisting of one network management system, a few element management system and several agent-ATM switch pairs, respectively. The effects of one TMN command on the local call processing performance of the component ATM switch an analyzed using Jackson's queueing model. The TMN command considered is the permanent virtual call connection, and the performance measures of ATM switch are the utilization, mean queue length and mean waiting time for the processor interfacing the subscriber lines and trunks directly, and the call setup delay of the ATM switch.

  • The purpose of this study is to propose the policies for preservation, formation and management of Korean rural landscape. For this, the current rural landscape policies are examined and recent legislative changes are also surveyed. The Landscape Law and the Comprehensive Countermeasures for Rural Landscape Improvement are the most significant changes. The proposed issues are as follows: 1. the establishment of rural landscape planning system, 2. the arrangement of the criteria and guideline for rural landscape planning and design, 3. the re-arrangement of the rural landscape index and landscape map, 4. the survey and management of the rural landscape amenity, 5. the revitalization of the landscape projects for rural area, 6. the pragmatic connection with other law and system(especially the Landscape Law), 7. the education and cultivation of the rural landscape expert groups.

  • These days, the damage of noise has increased seriously by rapid change of life style because of the centralization of urban population, and the rapid increase of traffic. The Ministry of Environment has emphasis on the systematic management about the noise of daily life and the close connection of daily noise management policy with relevant ministries, and put into practice "the master plan of lessening the noise of daily life" from year 2006. This study tried to find out the reduction methods and the effective management of railway noise in the action plan of railway part of "the master plan of lessening the noise of daily life". According to this study, railway noise can be reduced greatly by taking action of railway detail plans. The cause of railway noise varies by rolling stock, track and more, so the reduction methods of railway noise can be studied specially, scientifically and constantly in every field.

  • We propose a distributed anchor Crossover Switches (CX) searching algorithm to play an important role in ensuring fast and seamless handoff control in wireless ATM networks. Within networks that are grouped together, connection management is done for each group by anchor switches, and Permanent Virtual Circuit (PVC) with a narrow bandwidth is assigned between anchors for exchange of information. The proposed algorithm enables quick searching of a targeted CX, makes management of the overall network easier, and reduces system overhead or propagation delay time, thus providing fast and seamless handoff.

  • This study was intended to identify customer's response to CRM of fashion business.488 questionnaires were distributed to male and female respondents aged 16 to 55, and then analyzed by descriptive statistics, oneway-ANOVA, chi-square test, and factor analysis. As a result of customer information management, respondents evaluated taste, interest and demographic informations as most valuable. But they did not value personal and credit information. For CRM concept, 4 factors were determined: continuous care and suggestion, particular service to important customer, customer management program development, and customer convenience consideration. For CRM activity, 3 factors were determined: customization, information offering, and programmed service strategies. Respondents were having positive attitude toward CRM concept and activity of fashion business. Among customer loyalty programs, they affected by immediate and direct programs most. The preference of customer contact methods was differentiated by sex and age groups. Males and teenagers preferred e-mail, and females preferred catalog and telephone connection.

  • As the application area of XML extends to the database from simple contents, the technology for the storage and management of XML also grows with the XML. One of the main issues is how to efficiently manage the XML by using the previous DBMS. Many studies have been performed for the efficient management based on the XML application and database interface. However, the XML data is based on the object and has the hierarchical structure. Accorkingly, a modeling plan needs to store the XML data on the variety type of database. In this paper, for easier connection between XML application and database system, we have designed components for the transformation from XML DTD to ORDB schema. The method of the design for the transformation from XML DTD to ORDB schema is chosen the method of CBD.

  • The article reviewed the elderly health care management problems in policy development issue of the nation. Policy of Korean government on elderly health care has still not yet developed. The main stream of policy which is effective on elderly welfare policy is 'Elderly care are responsible by their families'. Now only those aged whose family members are not able to take care of their parents are receive custodial care at the non-profit nursing homes. This article examined the main stream policy in pro and cons aspects in relation to social changes such as: demographic changes. family structure changes. attitude changes. health care delivery system. and political settlement view points in connection with medical insurance program. Finally. a model for the elderly health care management was proposed which will provide chronic care services at the community level. such as nursing homes. day care centers. day hospitals, respite care units, and special care institute for dementia.

  • The government supports politic funds to Small Business having difficulties of insufficient capital and weak assets. Also the effect of governmental politic funds are evaluated better than the effect of substitute loans of the commercial bank. Especially governmental politic funds contribute to the external growth of the enterprise sales and the increment of total assets size. It is necessary however related supporting programs with funding provision to reduce the risk of insolvency politic funds of small business and reinforce the competitive power of company. This paper introduces the model of the corporate diagnosis system of the Small Business Corporation as part of these intention and analysis supported companies' management performance last four years and proposes direction of development.

  • Vehicular ad-hoc networks (VANETs) are self-organizing, self-healing networks which provide wireless communication among vehicular and roadside devices. Applications in such networks can take advantage of the use of simultaneous connections, thereby maximizing the throughput and lowering latency. In order to take advantage of all radio interfaces of the vehicle and to provide good quality of service for vehicular applications, we developed a seamless flow mobility management architecture based on vehicular network application classes with network-based mobility management. Our goal is to minimize the time of flow connection exchange in order to comply with the minimum requirements of vehicular application classes, as well as to maximize their throughput. Network simulator (NS-3) simulations were performed to analyse the behaviour of our architecture by comparing it with other three scenarios. As a result of this work, we observed that the proposed architecture presented a low handover time, with lower packet loss and lower delay.
