The technology acceptance model (TAM) is a lot of cited in information technology adoption and usage researches. But TAM has been conducted primarily in volitional environments of the adoption of new technology. This paper discusses technology acceptance in accounting information systems to examine TAM with Characteristics of Organizations and Individuals in mandated using Combined Guard System. Combined Guard System is a scientific guard system that is composed of automated surveillance system, automated sensing system and control system. GOP Scientific Guard System is operated by GOP unit in Korean Army O Division from 2006. In this study, using the extended technology acceptance model, we have analyzed factors which affect the usage intention of GOP Scientific Guard System in mandated using environment. Based upon previous researches, we have selected Support of management unit, Training, Perceived Risk, Subjective Knowledge and Computer Self-efficacy, perceived usefulness, perceived ease of use, and usage intention as variables and proposed a research model. We collected 253 survey questionnaires from Korean army officer and soldier who are serviced at GOP unit in O Division, and analyzed the data using SPSS 12.0 and SmartPLS 2.0M3. According to the results by PLS analysis, According to the results by PLS analysis, Training and Subjective Knowledge did not affect Perceived usefulness, but the other hypotheses were accepted. And Perceived usefulness, and Ease of use influenced the Usage intention. The results of this study will increase Characteristics of Organizations and Individuals on GOP Scientific Guard System and eventually contribute to establishing the activation of Combined Guard System.

최근 금융업계의 차세대시스템 구축이 본격화됨에 따라 구축방식의 의사결정에 대한 체계적인 접근법이 요구되고 있다. 본 논문에서는 금융 차세대시스템 구축 프로젝트 수행에 요구되는 소요시간과 투자비용에 따라 차세대시스템 구축 접근방법을 혁신적(Big Bang) 방식과 단계적(Phase) 방식으로 구분하고, 시스템 구축 단계에서 두 가지 대안을 체계적으로 비교하기 위하여 AHP(Analytical Hierarchy Process) 기법을 적용한 금융권 차세대시스템 구축방식 평가방법론을 제시하였다. 계층적 평가지표 도출을 위해 비용, 성과, 위험을 최상위 기준으로 설정하고 각각의 세부 평가 항목을 3단계까지 도출하였다. 도출된 평가 항목을 토대로 설문조사 대상자를 금융회사의 내부 현업 담당자와 외부 SI업계 전문가를 구분하여 금융 차세대시스템의 구축방식 선호도에 대한 비교분석을 수행하였다. 부석 결과 과거 국내 금융회사에서 많이 이루어진 혁신적 방식보다 단계적 방식에 대한 선호도가 높게 나타났다. 이러한 결과는 아키텍처 중심의 청사진을 통해 단계적으로 시스템을 구축하고자 하는 최근의 경향이 반영된 결과라 할 수 있다. 또한 회사유형에 따라 평가 항목별 가중치에 대한 차이가 나타났다. 즉, 금융회사는 시스템을 운영하는 입장에서 위험을 회피하고 안정성을 강조한 반면에 IT서비스회사는 차세대시스템을 구축하기 위한 비용과 그에 따른 성과를 강조하는 경향이 나타났다. 본 연구는 향후 금융 차세대시스템의 구축방법 결정시 가이드라인으로 활용될 것으로 기대된다. This study defines the Next Generation System(NGS) built by domestic financial businesses and classifies their architecture into two typical types according to the duration of the project and the relative cost of IT investment in the short term: the Big Bang approach and the Phase approach. Herein, we study the two approaches as alternatives in developing the Next Generation System, and derive the factors that are to be considered in the evaluation of the two alternatives for financial businesses. The set of standards for the choice between the two models are grouped into categories that constitute performance evaluation for IT-Cost, Performance and Risk. We drill down further into each category to second and third subordinate levels to derive detailed selection criteria. Based on the criteria drawn from the study, we conduct a survey with information system planners, IT managers and specialists at financial companies who are currently planning, developing or have completed a NGS. Results are analyzed using the AHP methodology to compare and understand the different approach in the implementation of NGS for financial business. According to the research result, survey respondents showed the different evaluation weight between alternatives by industry, but the Phase approach showed higher preference than the Big Bang approach in the building method.
