In this paper, we give a detailed description of KDSM(KAIST Distributed Shared Memory) system. KDSM is implemented as a user-level library running on Linux 2.2.13, and TCP/IP is used for communication. KDSM uses page-based invalidation protocol, multiple-writer protocol, and supports HLRC(Home-based Lazy Release Consistency) memory consistency model. To evaluate performance of KDSM, we executed 4 scientific applications and compared the result to JLAJLA. The results showed that performance of KDSM almost equal to JIAJIA for 2 applications and performance of KDSM is better than JIAJIA for 2 applications.

The current study investigated the impact of interaction between self-esteem and reward type on the effects of an international relief campaign. Self-esteem refers to how worthy a person feels about the self. Reward is differentiated by intrinsic or extrinsic type. An experimental research was conducted with 184 subjects by self-esteem ${\times}$ reward type. This research was progressed with two stages. At the first stage, questionnaires relative to participants' self-esteem and past experiences were distributed. At the second stage, the participants rated their responses after exposure to the campaign. Individuals with higher self-esteem showed more favorable message attitudes towards intrinsic reward type, yet those with lower self-esteem did not show a significant difference. Analyses for behavioral intention did not produce any significant result.

For multiprocessor systems, Earliest Deadline First (EDF) based on deadline and Least Laxity First (LLF) based on laxity are not suitable for practical environment since EDF has low schedulability and LLF has high context switching overhead. As a combining of EDF and LLF to improve the performance, Earliest Deadline Zero Laxity (EDZL) was proposed. EDZL is basically the same as EDF. But if the laxity of a task becomes zero, its priority is promoted to the highest level. In this paper, we propose Least Laxity Zero Laxity (LLZL) which is based on LLF. But context switching is allowed only if the laxity of a task on rady queue becomes zero. Simulation results show that LLZL has high schedulability approaching to LLF and low context switching overhead similar to EDF. In comparison with EDZL, LLZL has better performance in both of schedulability and context switching overhead.

Comes in into recent times and there is on with a level where the attack against the computer virus and the hacking which stand is serious. The recently computer virus specific event knows is the substantial damage it will be able to occur from our life inside is a possibility of feeling. The virus which appears specially in 1999 year after seemed the change which is various, also the virus of the form which progresses appeared plentifully The part virus does it uses the password anger technique which relocates the cord of the oneself. Hereupon consequently the vaccine programs in older decode anger to do the password anger of the virus again are using emulation engine. The password anger technique which the like this virus is complicated and decode anger technique follow in type of O.S. and the type is various. It uses a multi emulation engine branch operation setup consequently from one system and to respect it will be able to use a multiple operation setup together it will use the VMware which is an application software which it does as a favor there is a possibility where it will plan 'Virus Test Simulation' and it will embody.

In order to utilize BSC as an operational tool for communicating strategies across the hierarchies of the organization, a growing number of companies have tried to link BSC processes with other PI tools. Company D has carried out the SEM project to identify the causal structure between innovation activities and performance management in 2005 and 2006. The company synthesizes BSC and 6 Sigma methodologies at the BU level, and the new process made it possible to manage performances and make decision more "realistic" on the basis of information technologies. We expect that this study provide organizations, which have difficulties streamlining the performance management processes at the strategic level and those of operational level, with implications for realizing more "execution-oriented" RTE.

CRM의 장점은 원하는 고객에 대해서 마케팅 노력을 기울일 수 있고 그 결과로 마케팅 비용을 줄이고 효율을 높일 수 있는 것이다. 그리고 마케팅 전략 수립에 대한 방법의 변화와 그 수행방법의 변화가 CRM에 있기 때문에 여기에 따른 절차와 문화, 조직구조까지 변화 시킬 수 있다. 이를 방지하기 위하여 CRM교육이 필요하며, 그 중요성을 인식하고 실행하여야 한다. 그리고 경영환경에 적합한 마케팅 전략 수립이 필수적이다. CRM의 정확한 이해와 적합한 수행이 있어야만 병원경영의 목표달성에 도움이 된다. 그러나 CRM자체의 문제가 없는 것도 아니다. 무엇보다 전문 인력이 부족하면 시스템 구축과 마케팅이나 컨설팅 인력을 확보하여 프로젝트의 부실화를 방지하여야 한다. 다음은 실업자들의 업무패턴을 파악하고 사용자의 편의를 고려한 적용이 있어야 한다. 고가의 비용을 투입하여 CRM을 실행하였다 해도 사용자 교육의 미비가 생기면 효율이 감소될 것이다. 역시 CRM의 적용에 있어서 호환이 되지 않으면 통합비용으로 별도의 비용이 지출해야 하므로 비용의 증가를 감수하여야 한다. 환자의 의료의 질에 대한 만족은 환자의 주관적 개념으로 동일한 의료서비스에 대하여 환자들은 저마다 다르게 의료의 질을 평가하게 된다. 대부분의 환자들은 자신의 욕구와 의료의 질에 대한 기대를 가지고 병원을 방문하여 의료의 질을 평가하게 된다. 대부분의 환자들은 자신의 욕구와 의료의 질에 대한 기대를 가지고 병원을 방문하여, 그것을 의료제공자가 충족시키는 정도가 환자의 만족도를 결정하게 된다. 의료의 질은 의료서비스에 대한 만족과 밀접한 관련이 있다. 의료의 질과 만족은 강하게 연관이 있으면서도 양자는 분명히 다르다. 의료의 질에 대한 평가와 만족도는 매우 일치도가 높다고 볼 수 있다. 이것은 의료의 질적 수준이 높으면 환자만족도도 높다는 것을 의미한다. 따라서 본 연구는 병원의 환자관리를 위한 CRM 마케팅의 전기를 실증적으로 역설하고 이의 도입을 통한 효과와 문제점, 이에 대한 대응방안을 제시하고, 모범적인 CRM운영 사례를 제시함과 동시에 효과적인 의료의 질 경영을 구현하고 이것이 환자의 의료서비스 만족도를 높이는 결과인 것을 모색하는 것이 본 연구의 목적이다.

Access control techniques should be flexible enough to support all protection granularity levels. Since access control policies are very likely to be specified in relation to document types, it is necessary to properly manage a situation in which documents fail to be dealt with by the existing access control policies. The existing access control has not taken information structures and semantics into full account due to the fundamental limitations of HTML. In addition, access control for XML documents allows only read operations, and there exists the problem of slowing down system performance due to the complex authorization evaluation process. In order to resolve this problem, this paper designs a XML Access Control Management System which is capable of making fined-grained access control. And then, in developing an access control system, it describes the subject and object policies of authorization for XML document on which authorization levels should be specified and which access control should be performed.
