Since most of companies these days are utilizing the Information system actively, Information System is the most important factor which should be recovered in terms of Business Continuity. However, a lot of enterprises have been outsourcing their Disaster Recovery Center. Therefore, it is highly possible that the information system can not work well and result in the discontinuity of business when any trouble arises because of seperated plan of Business Continuity and Disaster Recovery. The study draws critical success factors for successful disaster recovery through researches of 42 documents. Then, factors are reviewed through interviews with consultants, experts of Business Continuity Plan and the information system officers of domestic banks. Domestic companies can make use of the study when they develop or renew Disaster Recovery Plan or Information System in terms of Business continuity.

Since information systems are pervasive in the business and non-business areas, the issue of extending researches on information systems to knowledge systems and e-business systems is one of the most profitable topics of researches. We propose a historical, discontinuous changes introducing ambiguity in explaining and interpreting innovative nature of three paradigms of systems: information systems, knowledge systems, and e-business systems. Resorting to the historical perspective in developing ideas into meaningful themes, we proposed a discrete continuity in interpreting changes of paradigms of systems. Discrete continuity may be explained by ambiguously-shared meaningful perspectives applied to different paradigms of systems and interpretive elements of each system. The discrete continuity has been adopted to make ambiguity utilized have instrumental contribution in researches. The engrafted ambiguity in systems design, development, and use could have enduring instrumental value in interpreting the types or variants of systems in each paradigm of systems.

Purpose This study aims to investigate factors that positively influence the continuous Artificial Intelligence(AI) Learning Continuity of business major students. Design/methodology/approach To evaluate the impact of AI education, a survey was conducted among 119 business-related majors who completed a software/AI course. Frequency analysis was employed to examine the general characteristics of the sample. Furthermore, factor analysis using Varimax rotation was conducted to validate the derived variables from the survey items, and Cronbach's α coefficient was used to measure the reliability of the variables. Findings Positive correlations were observed between business major students' AI Learning Continuity and their AI Interest, AI Awareness, and Data Analysis Capability related to their majors. Additionally, the study identified that AI Project Awareness and AI Literacy Capability play pivotal roles as mediators in fostering AI Learning Continuity. Students who acquired problem-solving skills and related technologies through AI Projects Awareness showed increased motivation for AI Learning Continuity. Lastly, AI Self-Efficacy significantly influences students' AI Learning Continuity.

Growing threats from environments and natural disasters cause information systems to suspend the operation of business. To assure the continuity of business, information systems should not halt in the emergency. This paper suggests an evaluation method for importance of information systems and verifies the method in a real organization. The results to the study can be utilized for establishing business continuity of organizations.

이 연구는 기록관리 환경이 디지털 기반으로 변화되어 가는 상황에서 대학 정보자원의 디지털 연속성 보장을 위한 실행 방안을 제안하기 위한 것이다. 이를 위해 국외 영국 TNA와 호주 NAA의 디지털 연속성 정책 사례를 조사·분석하고, 대학의 디지털 연속성 보장을 위한 정책개발에 필요한 시사점을 다음과 같이 도출하였다. 대학은 디지털 연속성 보장을 위해 디지털 자원의 '자산(asset)'적 가치를 파악하고 이용가능성 보장을 위한 선행 분석과 대응(위험관리 등) 체계를 갖추며, 대학 전 영역에 걸친 협업 체계를 조성해야 한다. 또한 대학의 정보자원에 적용가능한 실행 방안을 제안하기 위해 영국 TNA에서 제시한 디지털 연속성 보장 프로세스 4단계를 대학 사례에 적용해보았다.

This study aims to propose a reasonable and effective kiosk operation plan for hotels planning to introduce kiosks by verifying how the quality attributes of hotel kiosks, which have recently been rapidly increasing starting with mid-priced hotels, affect customer satisfaction and relationship continuity intention. An online survey was conducted for customers using hotel kiosks. 300 copies were collected, 61 insincere responses were removed, and 239 copies were verified. As a result of the analysis, first, hotel kiosk quality attributes, display color, device design, internal UI, amount of information, display brightness and response speed were found to have a significant impact on customer satisfaction and were partially adopted. Second, in terms of relationship continuity intention, the display color, internal UI, amount of information, and response speed were found to be significant and were partially adopted. Third, customer satisfaction showed significant results in relationship continuity intention. These research results showed partial differences from previous studies on general kiosk users and restaurant kiosk users, and based on these results, academic and practical implications were derived.

When the load in a multi-cell orthogonal frequency division multiple access (OFDMA) system is allowed to excessively increase in face of frequent handover, the cell area becomes smaller than the designed size, and thus continuity of quality of service (QoS) for handover requests cannot be guaranteed. To efficiently support the mobility of a mobile terminal (MT), we should adaptively cope with the resource demand of handover calls. This paper proposes a twofold resource-reservation scheme for OFDMA systems to guarantee continuity of QoS for various mobile multimedia services during MT handover from lightly to heavily loaded cells. Our twofold scheme attempts to guarantee service continuity for handover and to maximize resource allocation efficiency. We performed a simulation to evaluate our scheme in terms of outage probability, handover failure rate, total throughput, and blocking rate.

This note is devoted to establishing the variation continuity of the one-dimensional discrete uncentered multilinear maximal operator. The above result is based on some refine variation estimates of the above maximal functions on monotone intervals. The main result essentially improves some known ones.
