Many organizations operate security systems and manage them using the intergrated secutity management (ISM) dechnology to secyre their network environment effectively. But current ISM is passive and behaves post-event manner. To reduce cost and resource for managing security and to remove possbility of succeeding in attacks by intruder, the perventive security management technology is required. In this paper, we propose PRISM model that performs preventative security management with evaluating the security level of host or network and the sensitivity level of information asset from potential risks before security incidents occur. The PRISM can give concrete and effective security management in managing the current complex networks.

Recently, supply chain attacks against nuclear facilities such as "Evil PLC" are increasing due to the application of digital technology in nuclear power plants such as the APR1400 reactor. Nuclear supply chain security requires a asset management system that can systematically manage a large number of providers due to the nature of the industry. However, due to the nature of the control system, there is a problem of inconsistent management of attribute information due to the long lifecycle of software assets. In addition, due to the availability of the operational technology, the introduction of automated configuration management is insufficient, and limitations such as input errors exist. This study proposes a systematic asset management system using SBOM(Software Bill Of Materials) and an improvement for input errors using natural language processing techniques.

Recently, the paradigm of SOC investment has shifted from new construction to maintenance. This shift became more important for the highway system because it is as one of the most important SOC. In Korea, highway maintenance costs are about 20% of the total annual highway construction budget, which is about two-thirds of developed countries. In addition, establishing standardized guidelines for the highway maintenance operation is not in place. Therefore, in order for domestic road construction and maintenance technology to secure competitiveness in the global construction market, it is urgent to improve the management capacity for maintenance as well as the technology and management capacity. This study examines highway maintenance practices in OECD countries such as North America, Europe, Australia, New Zealand, and Japan to identify core elements of highway maintenance practice. It is imperative to establish a comprehensive management system based upon asset management principle. Even if the budget for the highway construction is reduced, investment in maintenance needs to be maintained.

The asset management of railway facilities is a total framework for finally supporting a safe and comfortable train service, which includes functions of supporting evaluation of condition and performance of infrastructures, making the decision method of repair or rehabilitation of deteriorated facilities, and lengthening the life cycle of structure through the decision of adequate cost and time of repair or reinforcement. In the range of the asset management, organization, human, the target, and information & data of company are included. Therefore, in this paper, appling the method of asset management analysis to the railway structures, the process of the risk assesment using BRE(Business Risk Exposure) and the basis of consisting optimized renewal decision-making are expressed.

2020년 7월 정부는 포스트 코로나 시대를 선언하며, 한국판 뉴딜 정책을 발표하였다. 한국판 뉴딜은 디지털인프라 구축, 비대면 산업육성, SOC 디지털화를 기본방향으로 내세웠으며 빅데이터, 인공지능(AI), 사물인터넷(IoT) 등 4차산업 핵심기술의 육성방안을 제시하였다. 최근 인천공항은 한국판 뉴딜 정부정책에 부응하기 위해 인천공항 K-뉴딜 프로젝트를 추진 중이며, 세부 전략과제로 자산관리의 디지털전환을 위한 IoT기반 스마트 자산관리시스템을 구축 중이다. IoT기반 스마트자산관리시스템은 인천공항에 위치한 실내외 이동형 자산에 대해 끊김없는 위치정보를 제공하는 시스템으로 기존 시스템(RFID) 대비 약 4억 원의 인적, 물적 자원을 절감하는 효과를 나타낼 것으로 예상된다. 본 논문에서는 IoT기반 스마트 자산관리시스템의 핵심기술인 실내외 연속측위 스마트 트래커와 네트워크의 구성, 저전력 위치정보 제공방법을 제시한다.

With the virtual asset market's rapid growth, government regulations on listing and trading procedures are expected. However, specific measures are currently lacking. To ensure stable inclusion in the institutional framework, precise regulations are needed for market development and investor protection. This study compares self-regulatory guidelines of the top domestic virtual asset exchanges with Korea Exchange's Preliminary Listing Examination Standards (2022) to enhance timeliness and relevance. It defines IEO, IPO, and ICO concepts and addresses conflicts of interest in IEO. Analyzing delisted virtual assets, it categorizes issues and classifies listing examination guidelines into formal and qualitative requirements. The study examines self-regulatory guidelines based on continuity, transparency, stability, corporate characteristics, and investor protection criteria, along with five special requirements for virtual assets. Improvement measures include regular disclosures of governance structure, circulation volume, and the establishment of independent audit institutions. This research further analyzes delisting cases, classifies issues, and proposes solutions. Considering stock market similarities, it offers measures based on the institutional framework.

In this study, a road pavement crack deterioration model was developed for a pavement road sections of the Sejong-city. Data required for model development were acquired using a deep learning-based road asset monitoring system. Road pavement monitoring was conducted on the same sections in 2021 and 2022. The developed model was analyzed by dividing it into a method for estimating the annual average amount of deterioration and a method based on Bayesian Markov Mixture Hazard model. As a result of the analysis, it was found that an analysis results similar to the crack deterioration model developed based on the data acquired from the Automatic pavement investigation equipmen was derived. The results of this study are expected to be used as basic data by local governments to establish road management plans.

Multimedia system security can be categorized into groups such as protection of multimedia asset itself and protection of multimedia systems which can process multimedia asset. Divided consideration for these two factors will not hurt the importance of security management. In this paper, managing practices for keeping security level of multimedia systems are induced and categorized.

Companies have been difficult to capture the minds of consumers by staying in the sales phase in order to sell products. The marketing and brand management strategies of more understanding consumers and systematically managing for the perception of them are becoming important. Since launched, EXR has implemented a systematic brand management process from its early stage. Based on the idea of 'brand asset by customer' by Kevin Lane Keller that the total of consumer brand knowledge ultimately completes the company brand power, 'brand asset', to satisfy areas of 'functionality' and 'design', EXR pioneered its ultimate brand asset which is 'CAPORTS' and established its own identity called, 'PROGRESSIVE'. For the success of a brand management, there must be a clear vision supported by the determination of a specific brand identity. Also, it needs to be shared by members of the organization, and to maintain and manage it in the long run, an integrated management strategy is essential. On the basis of such identity, EXR was able to carry out the integrated management for its brand and the overall implementation of the marketing strategy. Therefore, In this study, we seek for a sustainable brand management strategy of fashion brand by looking into the process of the EXR's brand establishment.
