Only a few P3P-based privacy aware systems address the discrepancy between a service provider's privacy policy and the user's typical concerns-hence, putting service usage at risk. Moreover, since users are typically nomadic in pervasive computing services, their specific privacy concerns would dynamically change according to the surrounding context. This leads us to develop a dynamically adjusting P3P-based policy for a personalized, privacy-aware service as a core element of secure pervasive computing. Hence, the purpose of this paper is to propose a pervasive P3P-based negotiation mechanism for privacy control which functions in a dynamic and flexible way.

Knowledge, technology and information have special characteristics different from the ones of normal consumer products and services. Especially the value of such information varies according to external elements such as the provided environment, their method of utilization, and the level and purpose, etc. of the user. In this study, the indicators of information customer value are developed and measured to enhance customer-based values with efforts for making new customers and maintaining existing customers. The result is as follows: 14 customer value indicators were developed. Among the indicators, value gained versus effort, reduced time for research idea investigation and savings in time searching for equipment, and tools and materials got the highest score, which means that time-saving effects were the most important. The field study of this paper was conducted from information users in the field of national R&D, and thus future studies could be conducted in various industries in many countries to attain generalized results.

The purpose of this study is to provide the direction of the policy forwelfare of the home - based service by identifying the problem and improvement of the home - based service. In the fast growing society like korea social welfare policy for the home - based service. The core hypotheses, of this research that home - based services canexpand social support network and improve life satisfaction were aceptedor rejected, In other words, while the home - based services expanded the lold people social support network through the activities of social workers and volunteers, these services considering the findings of the this study, we can conclude that the current home - based services provided by social welfare have an effect upon increasing old peoples social support. But these services have no effect upon improving life satisfaction index.

This paper is an exploratory study aimed at finding factors that influence the penetration of cellular mobile telecommunications which have seen rapid development since 1980s. The paper tries to find economy and policy variables to influence the penetration by means of the multiple regression analysis. This paper shows a model that explain the penetration ratio of cellular service. The model is based on data from 39 upper middle income and 39 high income countries. The result shows that GDP per capita and the service period of the cellular mobile telecommunication have influenced on the penetration ratio positively, and the tariff of the service negatively. But, it is the open area to study the impact of the telecommunications policy changes on penetration, and to set a model which could explain the nation-specific characteristics.

Since Korean government has implemented the "Number Portability System" in the domestic mobile communications market, mobile communication companies have been striving to hold onto existing customers and at the same time to attract new customers. This paper presents a competing risk model that considers the characteristics of a customer in order to predict the customer's life under the "Number Portability System." Three competing risks considered are pricing policy, quality of communication, and usefulness of service. It was observed that the customers who pay more are less sensitive on pricing policy younger people are less sensitive than older people to the quality of communication and women are more sensitive than men to the degree of usefulness of service. We expect that the result of this study can be used as a guideline for effective management of mobile phone customers under the Number Portability System.

The purpose of this study is to compare the standards and guidelines of long-term care facilities based on the physical environments and human resources in Korea, Japan, USA, and Australia. Ultimately, this study suggests the directions for amendments of long-term care service or running of the facilities in Korea. For achieving this purpose, we reviewed the homepage of national health departments, reports and articles of long-term care service, and acts related with long-term care in each country. This comparisons were carried in terms of physical environments, human resources by long-term care related acts and legal sanctions as means of quality control. This study implies that long-term care service guidelines or standards should be revised for developing the quality of our long-term care services.

The purpose of this article was to review the basic concept of the SERVQUAL scale and to evaluate its usefulness in health care settings. The SERVQUAL scale was developed by Parasuraman et al. in 1988. Its purpose was to provide an instrument for measuring the quality of service that would apply across a broad range of services with minor modifications in the scale. The SERVQUAL scale is based on gap theory, which indicates the difference between consumers' expectations and their assessment of the actual performance of a specific firm. It has five dimensions to define service quality. These dimensions include: (1) tangibles' (2) reliability' (3) responsiveness' (4) assurance' (5) empathy. While the SERVQUAL scale has been tested in a number of health care settings. the findings have been mixed. So. health care marketers should be cautious in their use of the SERVQUAL scale. However, it is rare to find instruments that are as well validated as SERVQUAL appears to be. As well the SERVQUAL scale provides valuable information about the quality of health care service.

Various inventory control theories have tried to modelling and analyzing supply chains by using quantitative methods and characterization of optimal control policies. However, despite of various efforts in this research filed, the existing models cannot afford to be applied to the realistic problems. The most unrealistic assumption for these models is customer demand. Most of previous researches assume that the customer demand is stationary with a known distribution, whereas, in reality, the customer demand is not known a priori and changes over time. In this paper, we propose a reinforcement learning based adaptive echelon base-stock inventory control policy for a multi-stage, serial supply chain with non-stationary customer demand under the service level constraint. Using various simulation experiments, we prove that the proposed inventory control policy can meet the target service level quite well under various experimental environments.

This study is to test some expected performances coming from the introduction child care electronic voucher system, and suggest some policy implications. At first, this study established causal model on the expected performances of child care electronic voucher system, and then tested it through structural equation model on the base of survey. Survey was made through sampling employees of child care facilities in Gwangju Metropolitan City. This study showed that the expected effects of child care electronic voucher system are significant. This study suggested some implications basing on this analytical results.

As the number of fields adopting ICT (Information and Communication Technology) increased, it was necessary to diagnose the information service status of corporations and present improvement plans in agriculture. Therefore, we designed and conducted various surveys to understand the information service status of domestic agricultural company corporations.The research included ways to utilize information technology, establishing infrastructure related to information technology, current status of information technology application and impact on performance. Specifically, the main purpose of this study was to subdivide related corporations by industry and sales level and provide differentiated management implications for each sector. This is because the type of information service and information technology support that each corporation needs varies greatly depending on the industry and sales level. We provide customized management and policy proposals based on descriptive statistics and regression techniques.
