In this paper several continuities and homeomorphisms in computer topology are studied and their applications are investigated in relation to the classification of subs paces of Khalimsky n-dimensional space $({\mathbb{Z}}^n,\;T^n)$. Precisely, the notions of K-$(k_0,\;k_1)$-,$(k_0,\;k_1)$-,KD-$(k_0,\;k_1)$-continuities, and Khalimsky continuity as well as those of K-$(k_0,\;k_1)$-, $(k_0,\;k_1)$-, KD-$(k_0,\;k_1)$-homeomorphisms, and Khalimsky homeomorphism are studied and further, their applications are investigated.

Payment Systems is one of critical infrastructures, which is increasingly dependent on IT. Failure to provide the payment services can bring disaster to national economy, which is the reason why business continuity of payment system receive much attention these days. Payment Systems are complex systems, which consist of multiple players: central bank, commercial banks, clearing house. The main purpose of this paper is to propose some business continuity strategies for the payment systems. First, in order to provide financial stability, this paper clarifies the concepts of business continuity plan(BCP). Second, this paper illustrates the processes to come up with business continuity strategies for the payment systems based on risk analysis and business impact analysis. Business continuity strategies are proposed in terms of two dimensions: vertical and horizontal.

Compared to other business discipline, business continuity is relatively new. In this post 9/11 era, we still do not have a meaningful tool to objectively and consistently measure the organization's disaster-readiness. The purpose of this study is to introduce various processes included in the business continuity management (BCM) and introduce the business continuity program maturity model(BCMM). The BCMM can serve two purposes: First, it provides a diagnostic tool for objective evaluation of BCM effectiveness. Second, it can suggest ways of improvement for the business continuity program by generating data from which meaningful benchmark analyses could be drawn.

This study verified the mediating effect of perceived value and the influence of kiosk device characteristics on relationship continuity intention to solve the difficult problems of hotel companies due to the development of current technology and hotel recruitment problems. Two hundred thirty-nine consumers who used kiosk devices in hotels were analyzed using SPSS 23.0 and Smart PLS 4.0. As a result of analysis and verification, it was found that the kiosk characteristics (playfulness, convenience, reliability, usefulness) had a significant effect on all perceived values (emotional value, functional value), and the perceived value also had a significant effect on the relationship continuity intention. Appeared as a result of the influence. However, it was found that the mediating effect of functional value in the relationship between convenience and usefulness among kiosk characteristics was dismissed. These results support the previous studies on hotel kiosks and have academic implications, as well as practical implications for practitioners of hotel companies.

In this paper, as a survey paper, we review many works related to fixed point theory for digital spaces using Lefschetz fixed point theorem, Banach fixed point theorem, Nielsen fixed point theorem and so forth. Besides, we refer some properties of the fixed point property of a digital k-retract.

In this paper, we introduce another statement of a digital $(k_{0}, k_{1})-homeomorphism$ which is suitable for an approach to write an efficient algorithm for discriminating digital images with respect to the digital $(k_{0}, k_{1})-homeomorphism$.

If the function of the national infrastructure is suspended due to natural disasters and social disasters, the damage of the national infrastructure can be a serious threat to the national security as well as the life, body and property damage of the people. In this paper, we examine the domestic and overseas trends of the national system protection system and examine the domestic and overseas trends of the national system protection system. The detailed function of the essential function continuity, essential function, succession order, authority delegation, continuity facility, continuity communication, We examined the specific issues related to testing, education and training, transferring control and directing authority, analyzing the system related to the national infrastructure protection plan, and examined the specific problems and suggested an effective improvement plan for the critical infrastructure protection system.

Recently, it has become an important problem to extract semantic objects from videos, which are useful for improving the performance of video compression and video retrieval. In this thesis, an automatic extraction method of moving objects of interest in video is suggested. We define that an moving object of interest should be relatively large in a frame image and should occur frequently in a scene. The moving object of interest should have different motion from camera motion. Moving object of interest are determined through spatial continuity by the AMOS method and moving histogram. Through experiments with diverse scenes, we found that the proposed method extracted almost all of the objects of interest selected by the user but its precision was 69% because of over-extraction.

The primary function of an electronic records management system (ERMS) is to support organisations in providing effective records management services by enabling efficient remote access to the organisations' records. This helps the organisation to continue running during emergency events, such as the COVID-19 pandemic. The need to study ERMS for accessing records remotely has increased dramatically, due to the increase in daily use. The situation arising from the COVID-19 pandemic has increased the need for implementing proper digital systems, such as ERMS, to enable efficient work processes and enhance business continuity. An ERMS has the potential to allow organisations to create records and workflows off-site. During a pandemic, the ability to structure processes digitally helps in maintaining operations remotely. This study aims to provide a narrative review of the ERMS literature with an emphasis on explaining the primary components of ERMS that act as enablers for the implementation of the system in the oil and gas sector of developing countries. The current study proposes ERMS roles and responsibilities that could enhance business continuity. The authors use a qualitative narrative review and analyse the literature related to this study and its findings. The results show that, in cases of risk or crises, staff members need to have easy access to their records and documents to remain productive. An ERMS allows professionals to remain active and work off-site. Thus, ERMS play a significant role in protecting an organisation's content through the monitoring and control over who has authorisation to access its records.
