The purpose of this study is to analyze that change of social environment, disability perspective and rehabilitation paradigm of Korea rehabilitation for the past 60 years and to propose future direction for rehabilitation of Korea. The major results of this study are summarized as follow : First of all, there is a disparity of 30 years between persons with disabilities and persons without disabilities for the perspective of social inclusion in Korea. Second, social environment is one of the most important effective variable on rehabilitation for persons with disabilities in Korea, it has been rapidly changed from agrarian society, going through industrial society and intellectual society, to convergence society. Third, disability perspective has been changing to universalist model with change of the social environment and also paradigm of the rehabilitation has been changing from the target of treat, education and training to the member of society that can empower and support persons with disabilities. Forth, rehabilitation policies have been changing from the welfare policies to the empowerment policies in company with change of paradigm. On the basis of the results, the following suggestions can be made : First, universalist model have to be permeated in the society at large. Second, rehabilitation paradigm should change to emphasize the holistic and universalist perspective. Third, the main purpose of rehabilitation policies are equality, mean and target of the policies are to emphasize universal services.

An cluster system used consist of large number of running servers, one has the problem that does the low availability occured by the high chance of the server failures and it is difficult to provide occuring software aging. In this paper, running cluster web servers consists of n primary servers and k backup servers, based on the operational parameters such as number of running primary servers, number of backup severs, rejuvenation period, rejuvenation time, failure rate of sewers, repair rate of servers, unstable rate of servers. We calculate to evaluate the rejuvenation policy such steady-state probabilities, downtime, availability, and downtime cost. We validate the solutions of mathematical model by experiments based on various operation parameters and find that the software rejuvenation method can be adopted as prventive fault tolerant technique for stability of system. The failure rate and unstable rate of the servers are essential factors for decision making of the rejuvenation policies.

The software rejuvenation method for highly available multiplex systems uses a pro-active fault-tolerant approach to handle system failures. The software rejuvenation prevents failures from occurring, while the previous methods recover from failures after happening. Especially, since the software aging proceeds fast in the software used for the multimedia mobile computing due to the loss of communications or data, the preventive method from failures using software rejuvenation can be used for the multimedia mobile computing. In this paper, according to the operational parameters such as rejuvenation period, rejuvenation time, failure rate and repair rate of the servers, number of running servers, duration of running time, and type of running modes, we calculate steady-state probabilities, downtime, availability, and cost of the multiplex systems using software rejuvenation method. We validate the closed-form solutions of the mathematical model by experiments based on various operational parameters and find that the software rejuvenation method can be adopted as preventive fault-tolerant technique. The failure rate and unstable rate of the servers are essential factors for the decision making of the rejuvenation policies.

Objective : he aim of this study is to describe on the definition of the welfare state and scope of the social welfare and to analyze the development of the social welfare policy for the disabled in South Korea. Methods : We described on the definition of the welfare state and scope of the social welfare and analyzed the social welfare policy and welfare policy for the disabled among Korean Government through literature review. Finally, We also analyzed the welfare policy for the disabled in the Roh Moo-hyun Administration. Results : Welfare policy or welfare policy for the disabled was developed as economic growth from 'selective welfare' to 'universal welfare'. Scope of the social welfare was expanded from 'minimum guarantee' of the Lee seong-man administration to 'participatory welfare' of the Roh moo-hyun administration and that was similar to the welfare policy of administration for the disabled. Conclusion : We suggest that occupational therapist based community should find unmet health need and provide home-based rehabilitation services to the disabled and the elderly.

This study is purposed to analyze how the utilization of rehabilitation services and the desire for service utilization changes with time, to explain the factors affecting service needs and to suggest direction of policy improvement for injured workers. Using the Workers' Compensation Insurance Panel Data ver.1~3, this study analyzed 5,004 observations. Panel regression analysis was performed using STATA to examine changes over time. Two key findings were made: first, the factors influencing the degree of need for rehabilitation services were age, educational period, ability on job performance, community service experience, re-employment and unemployment; second, the significant factors influencing the degree of need for rehabilitation services according to time were age, education period, unemployment, ability on job performance, and experience in using community services. That results were different from the previous cross-section analysis. These findings indicate that it is necessary to check and adjust the initial intervention contents after the end of the period of care on a timely base.
