정보시스템이 기업 활동의 중추적인 역할을 담당하게 됨에 따라 정보시스템을 안전하고 지속적으로 운영하기 위한 합리적인 방안을 모색하는 것은 기업의 활동의 연속성을 보장하기 위한 핵심적인 요소로 인식되고 있다. 최근의 기술 및 경영 환경의 급격한 변화는 정보시스템 재해에 대한 대책에 있어서도 종래의 기술 중심으로 업무의 지속성을 보장하기 위한 방안의 수립으로 변환하고 있다. 본 논문에서는 기업 활동에 치명적인 장애를 초래하는 재해에 대비하기 위한 비상계획의 개념과 변천과정을 살펴보고, 최근에 대두된 업무 지속성 관리의 측면에서 업무 지속성 계획을 수립하고 운용하는 방법론을 CCTA에서 제시한 수명주기를 중심으로 살펴본다.

최근 정보기술의 발달로 해킹 등 각종 보안위협이 증가하고 있으며 이는 기업 경영에 심각한 위협으로 다가오고 있다. 해킹을 당한 기업은 금전적인 손실과 더불어 기업 이미지에 심각한 타격을 입고 뒤늦게 정보보호의 중요성을 인식하여 보안 대책을 수립하고 있지만 주먹구구식 인 경우가 대부분이다. 본 논문에서는 기업의 중요자산과 정보시스템을 보호하기 위해 반드시 고려해야 할 보안관리 방안을 제시하고 SK텔레콤의 사례를 설명하려 한다.

조직 또는 기술경영에 대한 주요 의사결정(Directing)과 통제활동(Controlling)을 의미하는 거버넌스에 대한 중요성이 점차 부각되면서 조직에서의 정보기술 또는 정보보호 활동에 대한 거버넌스 표준과 블록체인 또는 인공지능 등 혁신적 디지털 기술에 대한 거버넌스 표준들이 속속 발표되고 있다. 본 고에서는 ISO/IEC JTC 1 SC 27에서 작업한 정보보호 거버넌스 지침(ISO 27014, 2nd 버전, 2020.12)과 ISO/TC 307에서 작업한 블록체인 거버넌스 지침(TS 23635, 2022,02)에 대한 주요 내용과 함께 국내에서 두 가지 거버넌스 체계를 구현하기 위한 과정에서 발견할 수 있는 이슈와 이를 해결하기 위한 과제를 제시하고자 한다.

Purpose This paper presents a new method of classifying online platforms. It also explains how to apply the framework using case studies and generate new insight about platform strategies and policy development. Design/methodology/approach This paper focuses on the relationship between platforms, especially the hierarchy and power relations, and broadly classifies platforms as follows: content/services, meta information, app stores, operating systems, and cloud. Both the content/service platform and the meta information platform have matching as their main function. However, most content/services tend to collect and access information through meta-information platforms, so meta-information platforms are closer to infrastructure than content/service platforms. App store, operating system, and cloud can be said to be platforms of platforms. A small number of companies in the US and China dominate platforms of platforms, and become the recent development and regulatory targets of their respective governments. Findings We should be wary of the attempts to regulate domestic platforms by importing foreign regulations that ignore the hierarchical structure that our framework highlights. We believe that Korea's strategy to become a true platform powerhouse is clear. As one of the few countries with significant companies in the area of meta information platforms, it will be necessary to fully utilize the position and advance into the strategically important area of platforms of platforms. Furthermore, it is necessary to encourage world-class companies to appear in Korea in the app store, operating system, and cloud. To do so, the government needs to introduce promotion policies to strategically nurture such platforms rather than to regulate them.

This research investigates the pivotal role of AI-enabled technologies in vitalizing the local economy. Collaborating with a leading search engine company, we examine the direct and indirect of an AI-based location search service on the success of sampled 7,035 local restaurants in Gangnam area in Seoul. We find that increased use of AI-enabled search and recommendation services significantly improved the selections of previously less-discovered or less-popular restaurants by users, and it also enhanced the stores' overall conversion rates. The main research findings have contributions to extant literature in theorizing the value of AI applications in local economy and have managerial implications for search businesses and local stores by recommending strategic use of AI applications in their businesses that are effective in highly competitive markets.

Purpose One of the reasons for the expansion of information systems in the enterprise is the increased efficiency of data analysis. In particular, the rapidly increasing data types which are complex and unstructured such as video, voice, images, and conversations in and out of social networks. The purpose of this study is the customer needs analysis from customer voices, ie, text data, in the web environment.. Design/methodology/approach As previous study results, the word frequency of the sentence is extracted as a word that interprets the sentence has better affects than frequency analysis. In this study, we applied the TF-IDF method, which extracts important keywords in real sentences, not the TF method, which is a word extraction technique that expresses sentences with simple frequency only, in Korean language research. We visualized the two techniques by cluster analysis and describe the difference. Findings TF technique and TF-IDF technique are applied for Korean natural language processing, the research showed the value from frequency analysis technique to semantic analysis and it is expected to change the technique by Korean language processing researcher.

Purpose The purpose of this study is to examine the effect that insecurity and autonomy of platform work have an influence on work-life balance and psychological well-being in an era of platform economy based on two characteristics of online platform work and self-determination theory. Design/methodology/approach This study suggested the structural equation model integrating two antecedents, insecurity and autonomy, work-life balance, and psychological well-being and proposed five hypotheses driven from the research model. A total of 334 valid samples were collected from platform workers by employing questionnaire including 24 question items of four constructs. Findings Three hypotheses were supported and one hypothesis was not supported at the significance level of 0.05. Insecurity of platform work has a negative influence on work-life balance at the significance level of 0.01, whereas insecurity of platform work has no a significant influence on psychological well-being. Autonomy of platform work has a positive influence on both work-life balance and psychological well-being at the significance level of 0.01. Work-life balance has a positive impact on psychological well-being at the significance level of 0.001. Insecurity have an influence on psychological well-being indirectly through mediation of work-life balance. Implications for academicians and practitioners were suggested.

Land monitoring involves systematically understanding changes in land use, leveraging spatial information such as satellite imagery and aerial photographs. Recently, the integration of deep learning technologies, notably object detection and semantic segmentation, into land monitoring has spurred active research. This study developed a web service to facilitate such integrations, allowing users to analyze aerial and drone images using CNN models. The web service architecture comprises AI, WEB/WAS, and DB servers and employs three primary deep learning models: DeepLab V3, YOLO, and Rotated Mask R-CNN. Specifically, YOLO offers rapid detection capabilities, Rotated Mask R-CNN excels in detecting rotated objects, while DeepLab V3 provides pixel-wise image classification. The performance of these models fluctuates depending on the quantity and quality of the training data. Anticipated to be integrated into the LX Corporation's operational network and the Land-XI system, this service is expected to enhance the accuracy and efficiency of land monitoring.

This study is analyzed the cited documents after selecting Management Administration Economics Trades in order to comprehend the study sphere and tendency for the three years from 2005 to 2007 in which 540 articles and 22,147 cited documents. In the analyzing result, the scientific study exchange communication activities is making progress more actively by the sole study rather than the joint study and over 77% of references are published before around 10 year-old, specifically 8.5 year-old documents have been used the most. The half-life period is 10.9 years for domestic books and 11.1 years for international books. For the journals, it is 6.0 years for domestic and 8.2 years for international which tells international articles are slightly longer half-life period than domestics.
