In this study the hospitality industry's leading companies, hotel companies affect the relationship between the performance information system, customer orientation, service orientation, to identify the target. Convenience extraction methods to Employees engaged in hotel in Seoul & Busan sampling was investigated. In order to derive the results of the study, the study hypothesis was based Information System for customer orientation service orientation, affect the relationship between the performance was investigated. Service orientation and customer orientation significantly affected, but the results of the hypothesis testing, the usefulness of information system technology acceptance model for ease of service orientation and customer orientation in the not significantly affect was not. Service orientation and customer orientation, business performance, but significant results derived significant personal achievements the results derived were not.

Corporate ESG performance (environmental, social, and corporate governance) reflecting a company's strategic sustainability has emerged as one of the main factors in today's investment decisions. The traditional ESG performance rating process is largely performed in a qualitative and subjective manner based on the institution-specific criteria, entailing limitations in reliability, predictability, and timeliness when making investment decisions. This study attempted to predict the corporate ESG rating through automated machine learning based on quantitative and disclosed corporate financial information. Using 12 types (21,360 cases) of market-disclosed financial information and 1,780 ESG measures available through the Korea Institute of Corporate Governance and Sustainability during 2019 to 2021, we suggested a deep neural network prediction model. Our model yielded about 86% of accurate classification performance in predicting ESG rating, showing better performance than other comparative models. This study contributed the literature in a way that the model achieved relatively accurate ESG rating predictions through an automated process using quantitative and publicly available corporate financial information. In terms of practical implications, the general investors can benefit from the prediction accuracy and time efficiency of our proposed model with nominal cost. In addition, this study can be expanded by accumulating more Korean and international data and by developing a more robust and complex model in the future.

ERP is the general trend of industrial information system and many companies are introducing strategically to strengthen the competitive power. This paper analyzes the efficiency of introducing companies of ERP system using DEA model. We also suggest the introducing of ERP system which can be benchmarked based on analyzed information. We evaluate the CCR, BCC efficiency and RTS of 38 introducing companies of ERP system. The result shows that three enterprises whose values of CCR efficiency are 1, and seven enterprises whose values of BCC efficiency are 1. RTS indicates IRS of 22 companies. DRS of 2 companies and CRS of 4 companies.

Today's firms face task of achieving competencies in two somewhat mutually exclusive areas. That is, due to fierce competition in the market, firms need to provide better products and services without losing cost advantage. In this respect, effective logistics management is one of the process that can yield a foundation of competitive advantage. Many firms are already using integrative supply chain management to achieve mutual goals of each firms within the supply chain. However, it is highly likely that inefficiency will occur because of different operations systems and organizational characters of each firms. Information system is receiving attentions as to reduce inefficiencies and gain competitive advantage. This study analyzes the effects of information integration on logistics performance to search the role of information system in supply chain management.

회계정보시스템은 재무적 자료를 수집.처리하여 회계정보를 산출하고 이를 조직내의 경영관리자와 외부의 정보이용자에게 전달하는 시스템이라 할 수 있다. 기업의 환경 및 조직구조 등은 회계정보시스템을 설계하는데 영향을 미치게 되며, 회계정보시스템의 설계자는 이러한 기업의 내적.외적 환경요인에 가장 적합한 시스템을 구축하고자 노력하여야 한다. 본 논문은 기업의 외부환경요인(환경의 불확실성)과 조직구조요인(조직의 집권화, 공식화, 조직규모), 전산화 환경요인(최고경영층의 지원, 사용자의 전산능력) 및 업무특성(업무의 비구조화 정도, 상호연관도, 업무의 난이도와 다양도)등이 회계정보시스템의 개발 및 실행, 산출정보의 특성(정보의 대상, 정보의 시점, 정보의 형태, 정보제공 빈도, 정보의 통합도)에 미치는 영향을 파악하고, 상호간의 적합도가 회계정보시스템의 성과에 미치는 영향을 연구할 것이다. 또한 국내기업의 회계정보시스템의 운용실태와 현황을 파악하여 문제점을 지적하고 개선방안을 모색하고자 한다.

기업 내 정보시스템의 중요성과 이에 대한 의존성이 높아짐에 따라 정보시스템 부서가 제공하는 서비스에 대한 기대가 날로 증가하고 있다. 그러나 현재까지 정보시스템 부서에 대한 연구들은 정보시스템 자체의 기능이나 운영에 대한 연구가 대부분이었다. 본 연구에서는 정보시스템 부서가 제공하는 서비스에 따라 기업의 경영성과에 미치는 영향을 분석하고 그 결과로 정보시스템 부서의 전략적 운영에 대한 지침을 제시하고자 한다.

최근에 기업 인수/합병은 경영환경의 불확실성과 심화된 글로벌 경쟁으로 선진기업들의 생존과 경쟁력 강화를 위한 긍정적 수단으로 빠르게 인식되어 가고 있으며, 많은 사례의 M&A시 시너지를 극대화 시키기 위해 기업간 정보시스템 통합이 이루어지고 있지만 통합 IS 구축 실패가 부각되고 있다. 이에 본 연구에서 M&A시 두 기업의 차이점이 성공적인 시스템 구축에 미치는지 영향을 연구하였다. 향후 발생할 M&A에 따른 통합 IS 구축 시 유의하게 고려해야 되는 주요한 기업간의 차이점을 파악하여 성공적인 시스템 구축에 기여할 것으로 기대된다.
