본 연구는 성공적인 M&A를 바탕으로 탁월한 성과를 실현하고 있는 KEB하나은행의 전산통합에 대한 사례 연구이다. KEB하나은행은 2018년 말 기준 국내외 영업점 896개, 임직원 12,881명, 총자산 326조, 당기순이익 1조9천억 원을 실현한 국내 시중은행 중 하나이다. 본 연구의 목적은 KEB하나은행의 M&A이후 전산통합(Information system integration)에 대한 독특한 사례와 전략을 통해서 시사점을 제공하는데 있다. 이를 위해 KEB하나은행 전산통합 관련 기업의 자원상황, 전략, 성과 등을 다양한 정보를 활용해 찾고, 자원제약이론(Resource dependency theory)과 기업가정신 브리콜라주(Entrepreneurial bricolage)에 대한 기존 연구들을 살펴보았다. 사후통합과정에서 조직의 성공적인 전산통합을 위해서는, 자원제약이론 관점에서 조직의 자원현황을 파악해야 하며, 이를 해결하기 위한 전략을 선택하여 추진해야 한다. 자원 제약 상황에서 성공적 전산통합을 위해서는 기업가정신 브리콜라주 전략이 필요할 것이다.

Increasing number of corporations applies IT service management systems to optimize IT service delivery and support processes. For this reason, implementation experiences and effect of IT service management system are growing concerns for IT managers and researchers. This case study analyzes implementation experiences on an ITIL based service management systems in an medium sized corporation. The exploratory case analysis revealed that systems and service quality were improved from the implementation. This study will contribute to the successful implementation of IT service management system and developing a research model of IT service management process.

This paper is concerned with the development case of CEA(Course-Embedded Assessment) design tool for engineering education accreditation operations department for CEA system implemented. Each university or programs are already devoting efforts to build research and CEA system for CEA applied to. In order to effectively apply the CEA studies for each program it is required and particularly, the preferred way to build an operating system is considered a difficult situation of the course unit. Therefore, this case study and to propose a method and procedures required to assessment the design basis for curriculum and program assessment unit in terms of the applicability of CEA, proposes a virtual application results. The information proposed in this case study is determined that could be used in the design for the outcomes and assessment of a variety of programs as one of the steps to build the CEA systems.

In this study, we develop the Genetic Fuzzy System(GFS) to estimate the link traveling speed. Based on the genetic algorithm, we can get the fuzzy rules and membership functions that reflect more accurate correlation between traffic data and speed. From the fact that there exist missing links that lack traffic data, we added a Case Base Reasoning(CBR) to GFS to support estimating the speed of missing links. The case base stores the fuzzy rules and membership functions as its instances. As cases are accumulated, the case base comes to offer appropriate cases to missing links. Experiments show that the proposed GFS provides the more accurate estimation of link traveling speed than existing methods.

The main purpose of this paper Is to develop the Management Resource Analysis System for KOTRA which is based on Activity Based Costing(ABC). Because the products and services of KOTRA are exclusive and include a government subsidy, we need develop a different system from the private firm's ABC system. The Management Resource Analysis System that we propose is embodied using JAVA and JSP within an UNIX environment and developed as a Web-enabling base. It is expected for aiding a manager's decision-making such as resource inquiry, standard resource analysis, estimating the ratio of a government subsidy, case based reasoning, what-if analysis. The results of this paper suggest what points are to be considered when we apply ABC for Government Investment Corporation.

This paper presents a data-based stability analysis of a MIMO linear time-invariant discrete-time system, as an extension of the previous results for a SISO system. In the MIMO case, a similar discussion as in the case of a SISO system is also applied, except that an augmented input and output space is considered whose dimension is determined in relation to both the orders of the input and output vectors and the numbers of inputs and outputs. As certain subspaces of the input and output space, both output data space and closed-loop data space are defined, which contain all the behaviors of a system, respectively, with zero input in open-loop and with a control input in closed-loop. Then, we can derive the data-based stability conditions, in which the open-loop stability can be checked by using a data matrix whose column vectors span the output data space and the closed-loop stability can also be checked by using a data matrix whose column vectors span the closed-loop data space.

Despite their various similarities, Seoul's' Gangnam and Seocho districts showed different patterns in the adoption of the RFID household-based waste charging system. Gangnam, one of the 25 wealthiest districts in Seoul, first adopted the RFID system in 2012, but decided abandon it a year later due to inconvenience, sanitation, budget limitations, and management related issues. Unlike Gangnam, Seocho, a largely similar district to Gangnam, started to implement the RFID system in 2015 and successfully adopted this innovation. In this paper, we explain the adoption behaviors of these two districts using a Technology Hype Curve Model with 5 stages. Unlike traditional technology adoption theory, the Hype Curve Model concentrates on the big chasm between early majorities and late majorities, which is a core reason for discontinuity in innovation diffusion. Based on our case study result, the early majority easily gave up adoption due to immature technological and institutional infrastructure. However, Seocho district, who waited until the deficiencies had been sufficiently fixed since late majorities, succeeded at incremental diffusion. Since its invention by Gartner cooperation, the Hype Curve Model has not received enough attention in academia. This paper demonstrates its explanatory power for innovation diffusion. Similarly, this paper focuses on the importance of institutional framework in the diffusion of innovation. Lastly, we compare the behavior of two local governments in supporting and diffusing RFID systems to draw relevant policy implications for innovation diffusion.

Computer aided process planning(CAPP) is a key for implementing CIM. It is bridge between CAD and CAM and translates the design information into manufacturing instructions. Generally, manufacturing is an area where intelligent systems will not be able to rely on methods requiring formalized knowledge. Manufacturing lacks a body of knowledge that is specific, formalized, and rigorous, and which can be coded as rules or procedures. Thus expertise in manufacturing is developed over a period of many years. Case-based reasoning(CBR) offers a new approach for developing intelligent system. In the case-based approach the problem solving experience of the experts is encoded in the form of cases. CBR's retrieval process can be divided to two step. The first step is matching step, and the second step is selection step. For selecting base case, new preference heuristics were introduced using similarity concept. Similarity concept has three has three dimensions, i.e. entity similarity, structural similarity, and goal similarity. In this paper, bolt's process planning was selected an application domain. Following the test result, the new preference heuristics were approved as a useful procedure in CAPP.

The manufacturing environment is rife with nonlinear processes. In this context, an intelligent production controller should be able to predict the dynamic behavior of various subsystems as they react to transient environmental conditions, the varying internal condition of the manufacturing plant, and the changing demands of the production schedule. This level of adaptive capability may be achieved through a coherent methodology for a learning coordinator to predict nonlinear and stochastic processes. The system is to serve as a real time, online supervisor for routine activities as well as exceptional conditions such as damage, failure, or other anomalies. The complexity inherent in a learning coordinator can be managed by a modular architecture incorporating case based reasoning. In the interest of concreteness, the concepts are presented through a case study involving a knowledge based robotic system.
