전자정보기술의 발달로 인해 도서관 서비스제공은 정보화시스템에 대한 의존 비중이 커져가고 있다. 이러한 상황의 변화에 따라 본 연구는 이용자의 도서관 정보화에 대한 성과지각과 정보화를 통한 이용 만족은 전반적 만족에 중요한 선행요인이 될 것으로 추론하였다. 뿐만 아니라 기존 연구는 대체로 도서관의 서비스제공측면에서 이용자의 인식이나 만족을 조사하였으나 본 연구는 시각을 달리하여 이용자측면에서 단순 열람목적의 일반적 이용과, 전문정보구득 목적의 전문적 이용패턴이 정보화 성과지각에 어떻게 다르게 영향을 미치는지에 대해서 조사하였다. 또한 서비스품질차원이 정보화성과지각과 이용만족에 미치는 영향을 조사하였다. 마지막으로 서비스품질차원이 정보화성과지각과 이용만족에 미치는 영향을 확인하였다. 본 연구의 실증분석 결과는 첫째, 도서관 이용자의 열람 등 일반적 목적 이용이 정보화성과지각에 영향을 미치는지 검증하고자 하였으나 유의한 수준에 미치지 못했다. 둘째, 도서관 이용자의 특정 정보구득 등 전문적 목적의 이용이 정보화성과지각에 유의한 정의 영향을 미쳤다. 셋째, 일반적 서비스품질인 상호작용품질, 결과품질, 물리적환경품질 차원은 정보화성과지각에 유의한 영향을 미쳤으나 정보화이용만족에는 유의하지 않았다. 마지막으로, 도서관 이용자의 정보화성과지각과 정보화이용만족이 전반적인 만족을 선행하고 있음을 밝혔다. 이를 통해 도서관의 정보화시스템을 어떻게 이용자중심으로 체계화하여 발전시킬 것인지에 대해 심층적인 고찰이 필요함을 확인하였다.

We suggest a Business Performance Information System with Knowledge Discovery in Databases(KDD) as a key component of integrated information and knowledge management system. The proposed system measures business performance by considering both VA(Value-Added), which represents stakeholder's point of view and EVA(Economic Value-Added), which represents shareholder's point of view. In modeling of Business Performance Information System, we apply the following KDD processes : Data Warehouse for consistent management of a performance data, On-Line Analytic Processing(OLAP) for multidimensional analysis, Genetic Algorithms for exploring and finding dominant managing factors and Analytic Hierarchy Process(AHP) for applying expert's knowledge and experience. To demonstrate the performance of the system, we conducted a case study using financial data of Korean automobile industry over 16 years from 1981 to 1996, which is taken from database of KISFAS(Korea Investors Services Financial Analysis System).

To manage a cluster of distributed server systems, a number of management aspects should be considered in terms of configuration management, fault management, performance management, and user management. System performance monitoring and reporting take an important role for performance and fault management. In this paper, we present distributed system architecture modeling of a performance monitoring and reporting tool. Modeling architecture of four subsystems are introduced: node agent, data collection, performance management & report, and DB schema. The performance-related information collected from distributed servers are categorized into performance counters, event data for system status changes, service quality, and system configuration data. In order to analyze those performance information, we use a number of ways to evaluate data corelation. By using some results from a real site of a company and from simulation of artificial workload, we show the example of performance collection and analysis. Since our report tool detects system fault or node component failure and analyzes performances through resource usage and service quality, we are able to provide information for server load balancing, in short term view, and the cause of system faults and decision for system scale-out and scale-up, in long term view.

Measuring performance of corporate information system has become one of the core issues in that development of the information system requires substantial amount of investments and the system works as a crucial leverage to enhance competitive edge. Most of the previous researches for performance of the information system have narrow and limited focus on such as the effect of user satisfaction and productivity. This paper suggests a model to measures the comprehensive performance which is classified as user scope (user involvement and satisfaction), operational scope (task productivity, task innovation, customer satisfaction, management control) and efficiency scope (financial performance), and to represent the relationship among the scopes by the path analysis model. Followings are conclusions from statistical hypothesis test of the model: (i) user involvement through user satisfaction has positive effect on all the performances in the operational scope, (ii) task innovation and customer satisfaction in the operational scope has statistically significant impact on financial performance but task productivity and management control do not. This conclusion indicates that task productivity and management control has the long term effect in nature, and evaluation of the information system has managerial implication when it Is measured in comprehensive performance which includes internal operational performances as well as financial performance.

Recently, an effective building and utilization of information system are essential in franchise firms as well as corporate management. Accordingly, this study is to examine the structural relationships among partnership quality of supplier, trust with a supplier and commitment, and franchise information system performance based on Henderson's(1990) information system partnership model and Lee and Kim's(1999) partnership model. For these purposes, the authors developed several hypotheses. The data were collected from 173 franchisors and analyzed with SPSS 18.0 and AMOS 18.0 The results are as following. First, sharing knowledge, interdependence, and mutual benefit influence supplier trust, but do not influence commitment. Second, supplier trust affect commitment and it prove that supplier trust is a full mediating role between partnership quality and commitment of franchise and information system supplier. Third, both supplier trust and commitment have a positive effect on performance of franchise information system. Therefore, it implies that supplier trust is significant factor in an performance of franchise information system. At the end of this paper, managerial and theoretical implications, limitations and future research directions were suggested.

In order to improve business competency by the IS(Information Systems), every enterprise needs to evaluate the current level of IS performance and their utilization. The evaluation that measures the performance of enterprise information systems and diagnoses their effectiveness of business goals and efficiency of resources should represent the useful informations based on sustainable goal-oriented viewpoints to managers. This work develops an integrated evaluation system for continuous maturity of information systems performance, enabling enterprises to achieve their goals of information systems and related business strategies. The integrated evaluation system has been applied to performance measurement of information systems with a huge set of real data from domestic industries for three years, and proven reliable and practical.

The purpose of this paper was to evaluate performance of information system for one national university hospital in order to identify the factors influencing performance of information system. KPIs were collected for 181 users of information system (41 doctors, 104 nurses, and 11 medical supporting staffs, and 25 administrative staffs) from August 10 to 24, 2010. The results were as follows: Average performance score for input layer was 3.16; average performance score for process layer was 3.35; and average performance score for business layer was 3.57. Scores for input layer was lowest for nurses and scores for process and business layer were lowest for doctors. Results from the path analysis showed that system quality, demographic characteristics, and security significantly influenced management process but these factors except demographic characteristics influenced user satisfaction; and management process also significantly influenced user satisfaction.
