조현달 대한경영정보학회 1999 경영과 정보연구 Vol.3 No.-

Recently, the role of information system in a company has been changed a lot because of the rapid change in business environments and the development of information technology. It encompasses not only the supporting role which has aimed at improving business process but also the strategic role of which purpose lies in strategic use of information technology. Achieving this increased role of information system requires more emphasis on development of better and more effective ISP(information system planning). The purpose of this study is to identify organizational factors to affect successful information system planning. For this study, 240 survey questionnaires were mailed and 71 questionnaires were returned. 57 samples were used for the final analysis and 14 samples were excluded from analysis in that they didn't exercise official and systematic ISP. As the result of analysis, the factor which affect effective ISP is internal organization factors(size, ISP time frame, organizational planning resources, management style, organizational culture), not external factors(volatility and competitiveness). Among Internal factors, organizational culture and management style are the most significant factors which affect the effective ISP. The result of this study may have meaning in suggesting the way to develop effective ISP through the formalization of business process, more favorable users attitude toward IS and selection of an appropriate ISP methodology

조현달 대한경영정보학회 2005 경영과 정보연구 Vol.17 No.-

E-business might be characterized by open system through internet, fortification of relationship between the suppliers and customers in chain system of company, the collaboration among partners and the use of IT. For these characteristics, e-business companies are becoming to suffer such burdens as wide spread of global economy, industry deregulation, and the increasing number of new entrants. In this situation, e-business companies should maintain the flexible system to adapt fast changing environment. Information system planning has been the important research area for many years because of its strategic importance. Among various variables, organization and IS context have been researched for making successful ouput of ISP. In this paper, I studied the importance of flexibility in e-business environments. And further I examined the flexibility of IS, organization and ISP methodologies. The forthcoming paper, I expect to investigate the relationship between IS flexibility, organizational flexibility, ISP flexible methodologies and successful ISP.

정보시스템 계획의 상황적인 연구

조현달 대한경영정보학회 2000 경영과 정보연구 Vol.4 No.-

Recently, the importance of ISP(Information System Planning) has been increased because of rapid change and severe competition in business environments. Furthermore, the role of IS in the organization has included not only the supportive activities but also the strategic activities. Organizations can get the competitive advantages through the strategic use of IT by establishing effective and systematic ISP implementation. The main focus of this study is investigate the relationship among three subunits(organizational factors, the role of IS and effective ISP) based on the contingent settings which the process of ISP is implemented. The reasons that conceptual framework of this study is based on the contingent theory are as follow: First, ISP process itself has a series of complicated work which various elements in a company are involved. ISP externally must have the process to evaluate information technology (technology related with IS). Internally ISP process has a serious of works including determining information requirements to develop successful IS for other functional departments and identifying strategic opportunity of IS aligned with business strategy. Secondly, the activity of ISP is occurring on the continual basis. Business environments in which ISP process has implemented are changing continuously. Specific ISP methodology which was appropriate in a certain period of time does not work any more because of the rapid changes in business environments. For this reason managers can hardly expect successful ISP without considering external environments or internal environments such as organizational or management side. For this study, 240 survey questionnaires were mailed and 71 questionnaires were returned. 57 samples were used for the final analysis and 14 samples were excluded from analysis in that they didn't exercise official and systematic ISP. As the result of analysis, among the internal factors(organizational size, time frame of decision making, budget, management style, organizational culture) organizational culture, management style and time frame of decision making are identified as contingent factors on the effective ISP. The result of this study may have meaning in suggesting the way to develop effective ISP through the formalization of business process, more favorable users attitude toward IS and selection of an appropriate ISP methodology.

e-transformation의 전략수립 방법론에 관한 연구

조현달 대한경영정보학회 2004 경영과 정보연구 Vol.15 No.-

E-business is one of business innovations to get competitive advantage over other competing companies by utilizing information technology which can make to enhance the efficiencies and effectiveness through connecting one or several value activities. E-transformation is the process of business innovation to trans brick and motor companies to brick and click companies to accomodate e-business environments by means of digitalizing business strategy, business system, business process, and company cultures. In this results, the company can develop entirely new value chain of business and render enhanced services to customers. In this paper, I will represent several e-transformation evaluation models which are used to realize e-transformation(trans from brick and motor companies to brick and click companies). Also, I propose the strategic thrust model, which is composed of strategic targets(customer, suppliers, partners) and strategic tools(technology innovation, integration). This model is differentiated with evaluation models in that it can capture the rapidly changing business environments, especially strategic targets(customers, suppliers, partners)

실내 정보 가시화에 의한 u-GIS 시스템을 위한 Markerless 증강현실 방법

김희관,조현달,조현달 한국공간정보시스템학회 2009 한국공간정보시스템학회 논문지 Vol.11 No.1

증강현실 기술은 실제 환경에 컴퓨터로부터 생성된 가상 데이터를 실시간으로 덧씌우는 기술을 말하며, 이는 지리정보의 가시화 같은 작업에 매우 큰 잠재력을 갖고 있다. 하지만 지금까지 연구된 이동형 증강현실 시스템은 사용자의 위치를 파악하기 위해 GPS(Global Position- ing System)를 사용하거나 마커를 현장에 붙이는 방식을 사용하였다. 최근 연구들은 마커를 사용하지 않는 방법을 지향하고 있으나 많은 제약을 갖고 있다. 특히 실내의 경우는 GPS정보를 사용할 수 없기 때문에 실내 위치파악을 위해서는 좀 더 복잡한 문제들을 해결할 수 있는 새로운 기술이 필요하다. 최근 무선(RF, Radio Frequency)기반의 실내 위치 추정 연구가 활발히 수행되고 있지만, 이 또한 다량의 센서와 인식기를 설치해야한다는 제약이 존재한다. 본 연구에서는 한 대의 카메라를 사용하는 SLAM(Simul- taneous Localization and Mapping) 알고리듬을 이용한 위치 추정기법을 제시하였으며, 추정된 위치를 이용하여 증강현실을 통한 정보 가시화 프로그램을 개발하였으며 이를. 향후 실내외 seamless 연동이 가능한 모바일 u-GIS (Ubiquitous Geospatial Information System) 시스템에 적용할 것이다. Augmented reality is a field of computer research which deals with the combination of real-world and computer-generated data, where computer graphics objects are blended into real footage in real time and it has tremendous potential in visualizing geospatial information. However, to utilize augmented reality in mobile system, many researches have undergone with GPS or marker based approaches. Localization and tracking of current position become more complex problem when it is used in indoor environments. Many proposed RF based tracking and localization. However, it does cause deployment problems of large sensors and readers. In this paper, we present a noble markerless AR approach for indoor navigation system only using a camera. We will apply this work to mobile seamless indoor/outdoor u-GIS system.

ARVisualizer : A Markerless Augmented Reality Approach for Indoor Building Information Visualization System

김희관,조현달 대한공간정보학회 2008 Spatial Information Research Vol.16 No.4

Augmented reality (AR) has tremendous potential in visualizing geospatial information, especially on the actual physical scenes. However, to utilize augmented reality in mobile system, many researches have undergone with GPS or ubiquitous marker based approaches. Although there are several papers written with vision based markerless tracking, previous approaches provide fairly good results only in largely under “controlled environments.” Localization and tracking of current position become more complex problem when it is used in indoor environments. Many proposed Radio Frequency (RF) based tracking and localization. However, it does cause deployment problems of large RF-based sensors and readers. In this paper, we present a noble markerless AR approach for indoor (possible outdoor, too) navigation system only using monoSLAM (Monocular Simultaneous Localization and Map building) algorithm to full-fill our grand effort to develop mobile seamless indoor/outdoor u-GIS system. The paper briefly explains the basic SLAM algorithm, then the implementation of our system.
