To integrate heterogeneous distributed systems, there exist various researches and developments for the purpose of its adoption into enterprise environment. However, when web service technologies are applied, it is difficult to adopt directly existing software system development methodologies, because of the peculiar architecture of web services, such as service provider, service requester, and service repository. M4WSD(Method for Wes Services Development) is a web service development process model and involves procedures and guidelines to develop web services based on a Use Case model that is elicited from a business domain in requirement analysis. In this paper, we focus on how to determine key realization decisions for each service. The assessment guidelines help you to structure the problem of determining implementation strategy.

An ecconomically competitive automated manufacturing system integrates the various control processes and data used in design, manufacturing, sale and service of products. CIM is a way to achieve such integration through computers and computational techniques in design, planning, and manufacturing. Developing effective CIM architectures is hampered by integration problems. The key to resolving these problems lies in a better understanding of manufacturing function and how it is related to other manufacturing functions. Integration of CIM environment requires coordinated solutions to data management problems for individual application system as well as for exchange of data between these applications. This requires a common framework for data management throughout the CIM environment. This paper discusses the design paradigm as a framework for this purpose. Designing an organizational structure to meet those goals involves 1) analyzing the functions through functional decomposition, 2) developing a data model to coordinate functions. As a result, we propose an object-oriented design methodology for manufacturing information system.

Many researches are going on with regard to issues and problems related to mobile database systems, which are caused by the weak connectivity of wireless networks, the mobility and the portability of mobile clients. Mobile computing satisfies user's demands for convenience and performance to use information at any time and in any place, but it has many problems to be solved in the aspect of data management. The purpose of our study is to Implement Real-Time Mobile Query Processing System(MQPS) to solve problems related to database hoarding, the maintenance of shared dataconsistency and the optimization of logging, which are caused by the weak connectivity and disconnection of wireless networks inherent in mobile database systems under mobile client server environments. In addition, we proved the superiority of the proposed MQPS by comparing its performance to the C I S(Client-Intercept-Srever) model.

The development of dedicated network management system is essential to meet the following conditions: the system must run the configuring and repair processing for the dedicated communication network, and can manage new next generation data dedicated communication network of various types. In general it is effective that the system is consisted of decentralized module to be accessible for business logic and datum to remote area. To solve these problems, a method is to use object-oriented design techniques. That is, it is to abstract reusability objects and make component module using the abstracted objects. In this paper, we propose a management system of dedicated communication network service using object-oriented design techniques which are UML(Unified Modeling Language).

These days, the majority of public service area presents increment of utilizing a contracting-out with the following reasons such as cost-efficiency, maintenance of population changes in flexible manner, and convenience of management. The social changes have influence on policing structure and regional security system as well as problems associated with accepting the contracting-out in the public policing sector. However, many issues such as limited contracting-out sector, difficulty of encouragement of participation to private sector, and limitation of making a contract with contracting-out would be brought up when initiate contracting-out to the public policing sector. Changing security system to lower budget, planning restructure of organization, developing alterable partial contracting-out, establishing private and public cooperate system and rationalizing contract system are the suggestions to solve and modify the raising problems. This study suggests a differentiate regulation of policing services compare to currently existing contracting-out method to consider a distinctive working environment. The suggestions are as follows: 1. develop a security segregate model, 2. build a cooperative system between private and public policing sector, 3. broaden opportunity of participation of private policing sector, 4. open-competition among qualified private tender to make a contract. The private contracting-out in the public security service sector should be manage in different manner compare to other private contracting-out in government-oriented public service sector. Since work performance of each private contracting-out agency is strongly bond to safety of every civilian in the nation, it is essential to increase its standard of qualification of each agency.

The study was aimed at developing an independent hospice center model that would be best suited for Korea based on a literature review and the current status of local and international hospices. For the study, five local and six international hospice organizations were surveyed. Components of the hospice center model include philosophy, purpose, resources (workers, facilities, and equipment), allocation of resources, management, financial support and hospice team service. The following is a summary of the developed model: Philosophies for the hospice center were set as follows: based on the dignity of human life and humanism, help patients spend the rest of their days in a meaningful way and accept life positively. On the staff side, to pursue a team-oriented holistic approach to improve comfort and quality of life for terminally ill persons and their families. The hospice center should have 20 beds with single, two, and four bed rooms. The center should employ, either on a part-time or full-time basis, a center director, nurses, doctors, chaplains, social workers, pharmacists, dieticians, therapists, and volunteers. In addition, it will need an administrative staff, facility managers and nurses aides. The hospice should also be equipped with facilities for patients, their families, and team members, furnished with equipment and goods at the same level of a hospital. represented by a center director who reports to a board and an advisory committee. Also, the center director administers a steering committee and five departments, namely, Administration, Nursing Service, Social Welfare, Religious Services, and Medical Service. Furthermore, the center should be able to utilize a direct and support delivery systems. The direct delivery system allows the hospice center to receive requests from, or transfer patients to, hospitals, clinics, other hospice organizations (by type), public health centers, religious organizations, social welfare organizations, patients, and their guardians. On the other hand, the support delivery system provides a link to outside facilities of various medical suppliers. In terms of management, details were made with regards to personnel management, records, infection control, safety, supplies and quality management. For financial support, some form of medical insurance coverage for hospice services, ways to promote a donation system and fund raising were examined. Hospice team service to be provided by the hospice center was categorized into assessment, physical care, emotional care, spiritual care, bereavement service, medication, education and demonstrations, medical supplies rental, request service, volunteer service, and respite service. Based on the results, the study has drawn up the following suggestions: 1. The proposed model for a hospice center as presented in the study needs to be tested with a pilot project. 2. Studies on criteria for legal approval and license for a hospice center need to be conducted to develop policies. 3. Studies on developing a hospice charge system and hospice standards that meet local conditions in Korea need to be conducted.
