에너지 관리시스템(EMS)은 전력계통 제어용 종합 자동화 설비로서 전력계통 운영의 효율성과 전력공급의 신뢰도 향상을 위해 운용되고 있다. EMS의 중요한 기능중 하나는 일련의 계통해석 애플리케이션들을 통해 전력계통의 상태를 해석하여 안전도를 감시하고 평가하는 것이다. 이러한 계통해석 애플리케이션들은 상호간에 데이터의 일관성을 유지하기 위해 하나의 동일한 전력계통모델을 사용하여야 하며, 주어진 시간에서 여러 개의 독립적인 기능이 순차적으로 실행하여 계통의 상태정보를 실시간으로 제공해야 하므로 데이터의 입출력이 매우 빠르게 이뤄질 수 있어야 한다. 따라서 이러한 실시간 애플리케이션이 요구하는 신뢰성과 성능을 만족하기 위해서는 공통 네트워크 모델 기반의 데이터베이스와 그에 맞게 애플리케이션을 위한 데이터 입출력 구조나 기능을 설계하여야 한다. 본 논문은 전력IT 국가전략과제로 개발 진행 중인 한국형 EMS(이하 K-EMS)의 계통해석 애플리케이션을 위한 데이터베이스의 구조와 애플리케이션을 구성하는 세부기능들의 구조를 이러한 관점에서 기술하고자 한다.

As the internet is widely distributed. the intelligent search agent is commonly used to meet the needs of user. But these Intelligent multi-agents are so independent each other that they can not give reliability of information and also have difficulty in coping with the dynamic distributed environments due to the short of cooperation abilities among multiagent. To resolve these problems. this paper proposes the mechanism for efficient cooperation and information processing by creating agency within broker agent and clustering multi agent's agency using neural network. For reliability of information. we also propose the multiagent management mechanism that can improve the information update problems which are in existing search systems and evaluate the performance of this research through simulation.

The current research was conducted to examine the factors that affect outsourcing performances, and further investigate whether a discrepancy in performance exists between the medical institutions and hotel service institutions. The study surveyed both medical and hotel administrators for approximately two months, who managed outsourcing tasks. Total of 325 responses out of 350 distributed were collected. However, due to inadequate responses, six responses were excluded, amounting to total of 319 (155 medical institutions, 164 hotels) valid responses included in the final analysis. First, the informal outsourcing relationships between representatives of outsourcing service seekers and providers did not appear to have significant effects in terms of the levels of trust in neither medical institutions nor hotel industries. However, the relationships affected outsourcing degrees exclusively in medical institutions, showing the disparity between the two service institutions. This was explained due to the continuing long term efforts required to establish an informal relationship in medical institutions. Second, communication was shown to have positive effects on levels of trust in both medical institutions and hotel industries. This indicates a prominent outsourcing trait that emphasizes the significance of mutual cordial communication that contributes to establishing positive relationships. Third, opportunistic behavior of the outsourcing service providers appeared to negatively affect the levels of trust as well as outsourcing degrees for both medical and hotel industries. Therefore, opportunistic behaviors were found to have more tendencies to causing tension and discomfort rather than creating a relationship based on mutual credibility or conviviality. Fourth, the effect of service infrastructures on the level of trust did not appear to be significant on medical institutions, while showing positive influence on hotel industries. Additionally, service infrastructures were found to positively influence the outsourcing performance levels for both sectors. Fifth, trust between outsourcing service seekers and providers did not appear to have noticeable impact on the outsourcing degrees for either institution. On the contrary, trust appeared to have positive impacts on performance for both institutions. This further indicates that, when engaging in outsourcing, strengthening relationships through mutual partnership with outsourcing entities rather than establishing contractual relationships leads to improving the reciprocal trust, which in turn improves work results. Lastly the outsourcing degree of service seekers appeared to have positive impact on the outsourcing performance for both medical institutions and hotel industries, indicating the causal relationship between the affectability of outsourcing degrees and the following performance results.

In the case of traffic accidents, the broadcasting methods used in the mobile ad hoc network (MANET) cannot applied to transmit reliable message since moving high-speed in vehicular ad hoc networks (VANET) environments. In this paper, in order to guarantee transmitting reliable messages, we propose a collision avoidance method based-on directional antenna in VANET. In order to reduce interference from omni-broadcasting and to avoid hidden node problem from moving high-speed, we employed a forward-handed and backward directional antenna. The authors simulated the proposed method based on directional antenna and showed that the proposed method has been improved in respect to network utilization compared to existing VANET protocols.

Ubiquitous network consists of various devices using several heterogeneous protocols and requires seamless communication between devices. This paper proposes a new hierarchical event service and multiple event server architecture to implement the service under ubiquitous environment. The proposed event service classifies devices by logical and physical location to abstract the idiosyncrasy of used protocols, and reduces network load. Due to the design consideration, the proposed architecture removes transfer of duplicated event data effectively. As a result, we can guarantee the reliable event delivery. The prototype multiple event server architecture was implemented according to the proposed idea and evaluated its performance under a home network test bed.

본 연구는 내부조직관계에서 대인신뢰를 구성원들의 상대방(부하, 동료, 상사)에 대한 능력, 상호 믿음과 지원에 기반을 두는 것으로 정의하고, 조직구성원들의 협력적 관계는 조직결과의 향상을 가져올 수 있다는 것을 가정하여, 대인간의 신뢰가 조직생산성의 향상에도 영향을 미치는지를 확인하고자 한다. 연구결과에 따르면 직무수행에 관련한 의사결정에 참여도와 성과의 피드백만족도 그리고 개방적 의사 전달에 대한 만족도가 높을수록 업무생산성이 높아진다는 것을 알 수 있었다. 특히 대인신뢰에 기반을 둔 행정조직은 또 다른 관리적 도전인 문화적 다양성의 증대와 고객기대의 충족에 대처하게 되므로, 상사와 부하간의 대인신뢰를 구축하는 것은 구성원의 직무생산성을 증대시키고 조직몰입을 강화시킬 수 있는 원동력이 된다는 것을 알 수 있었다.
