  • An intelligent grid computing architecture is proposed and developed for transient stability constrained total transfer capability evaluation of future smart grid. In the proposed intelligent grid computing architecture, a model of generalized compute nodes with 'able person should do more work' feature is presented and implemented to make full use of each node. A timeout handling strategy called conditional resource preemption is designed to improve the whole system computing performance further. The architecture can intelligently and effectively integrate heterogeneous distributed computing resources around Intranet/Internet and implement the dynamic load balancing. Furthermore, the robustness of the architecture is analyzed and developed as well. The case studies have been carried out on the IEEE New England 39-bus system and a real-sized Chinese power system, and results demonstrate the practicability and effectiveness of the intelligent grid computing architecture.

  • The purpose of this study is to develop a recruiting platform resolving the mismatch between corporate job and job finder's competence in recruitment market. For this, we investigated technological trends and limitation on recruit platform. Based on the findings, this study investigates the trends and directions related to recruiting platform evolution and identified critical success factors and development strategies for successful development of recruiting platform. Two development strategies include employment of online resume and construction of database assessing job finder's competence. We also proposed target system architecture incorporating job database, competency assessment form, capability oriented resume. To analyze user requirement national competency standards and core job capability evaluation model were analyzed. Next, we designed integrated database, user interfaces, and dynamic functionalities using the forms developed in earlier stage. Finally, we assessed the fidelity of form item, integrity of database, and the usability of interface to evaluate the effectiveness of the system.

  • This paper presents an algorithm that evaluates load supplying capability(LSC) considering voltage constraint in composite power systems. To evaluate the LSC considering the voltage constraint, we apply tangent vector approach using an enhanced power flow method based on continuation algorithm. The validity and effectiveness of the proposed method is confirmed through the simulation of a model system.

  • This paper focuses on the evaluation of FACTS control on available transfer capability(ATC) enhancement. Technical merit of FACTS technology on ATC boosting are analyzed. More effective control means for line flow and bus voltage are required for appling FACTS. In this paper, the power flow calculation method for deriving FACTS control parameters based on current injection model(CIM) and newton method. Integrated scheme for ATC calculation considering dynamic characteristic of power system is suggested. Study is based on the IEEE 57-bus system demonstrate the effectiveness of FACTS control on ATC enhancement.

  • Despite heightened interest in and increased urgency surrounding the adoption of green business initiatives, firms seem to suffer from a limited understanding of the prerequisites and profit potentials of green strategies. Our proposed theoretical model suggests that green purchasing asa unique firmcapability must be built on internal organizational characteristics (i.e., top management commitment to environmental management, inter-functional coordination, and performance evaluation and reward systems), and that it eventually helps a firm obtain positive financial performance. We offer some research propositions about potential causal relationships among key constructs that can be empirically tested in future research. We conclude the current study with implications for both managers and researchers.

  • 폭발적으로 증가하는 데이터와 급변하는 기술적 발전은 과거와 현재를 넘어 미래를 예견하고 대응할 수 있는 새로운 분석 패러다임을 요구한다. 지시적 분석은 목표를 설정하고 이를 달성하기 전략을 수립함으로써 분석 결과의 제시에 그치는 게 아니라 사용자에게 목표 달성을 위한 구체적 행동과 그 결과를 요구한다는 점에서 기존의 기술적 분석, 예측적 분석과 근본적인 차이점을 보여준다. 그렇지만, 아직까지 구체적인 구현 방안이 널리 연구되고 있지 않고 있다. 본 연구에서는 연구 역량 강화를 목적으로 개발되고 있는 InSciTe Advisory 사례를 통해 고려할 사항과 어떤 개발 요소들이 필요한 지를 살펴봄으로써 해당 연구 분야의 기반을 제시하고자 한다. InSciTe Advisory 시스템은 5W1H 방법론을 중심으로 연구자가 롤 모델 그룹에 도달하기 위한 전략을 수립할 수 있음을 보이며, 평가 모델을 통해 Elsevier SciVal과 비교하여 126.5%라는 비교 우위적 평가 결과를 얻었다.

  • 본 연구는 익산다짐풍화 화강토를 사용하여 여러가지 응력경로 시험을 실시하고 관측된 거동을 정확하게 예측할 수 있는 능력으로서 Yasufuku구성모델을 평가하였다. Yasufuku구성모델로 계산된 변형률은 측정치와 대부분 잘 일치하지만 약간의 차이를 나타내기도 하였다. 측정한 변형률과 계산한 변형률 사이에 가장 큰 차이를 보인곳은 증가하는 응력을 갖는 비례하중이 작용할 때 축변형률에 대하여 일어났다. Yasufuku 구성모델은 익산다짐풍화 화강토의 거동을 일정 구속압력하에서 축하중이 작용할 때와 p'-일정하중이 작용할 때 정확하게 추정할 수 있었다.

  • This paper summarizes the results of a series of numerical evaluations (Lee et al., 2004, 2005) on the performance of pre-cracked reinforced concrete (RC) beams coated with polymeric composites. It was intended to numerically show the superior characteristics of the polymeric composites for enhancing the strength and ductility of existing concrete structures. Further, the predicted load-carrying and energy absorbing capacities of the beams were compared with previous experiments to verify the predictive capability of implemented computational model.

  • 본 연구에서는 최근 꾸준한 성장세를 보이고 있는 의료산업의 국내벤처기업에 대한 신용 평가를 위해 먼저 기업의 재무 요인과 비재무 요인을 구분하여 평가지표를 개발한 다음 Saaty(1980)의 계층분석과정(Analytic Hierarchy Process; AHP)방법론을 적용하여 각 지표의 중요도(가중치)를 산출함으로써 의료벤처기업의 신용평가모형을 제시한다. 재무요인의 상위지표로는 수익성, 안전성, 활동성, 성장성, 생산성을 선택하였고, 각 상위지표에 대해서는 2개씩의 하위지표를 정하여 모두 10개의 지표를 설정하였다. 또 비재무적 요인의 상위지표로는 경영자 능력, 기술성, 시장성, 사업성, 신뢰성의 5개 영역을 정하고, 각 영역에 대해 2-5개의 하위지표를 정하여 모두 17개의 지표를 설정하였다. 신용평가지표에 대한 평가를 위해 원주의료기기클러스터 내 소재하고 있는 금융기관 및 보증기관의 심사역을 대상으로 설문조사를 한 후 이를 분석하여 평가지표에 대한 가중치를 산출하였다.

  • A new method to evaluate the protection capability of distribution systems is reported in this paper. This work describes the fuzzy evaluation attributes and aggregation method of evaluation results based on a hierarchical model and the modified combination rule. An evaluation grade index called "protectability" is proposed and is expected to be a very uscful tool in defining an optimal protection and realizing the adaptive protection.rotection.
