Radio frequency identification(RFID) is a system of technology that transmits digitally coded identity information in the form of a unique serial number of an object or person wirelessly, using radio waves. The primary use of RFID has been in asset tracking. This makes it highly useful across various industries for effective and efficient conduct of different business processes like supply chain management (SCM). As the use of RFID expands, the use of this technology is observed in such industries as transportation, traffic payment, hospital and medical care, education, and retail. Although this technology offers immense potential, it faces multifarious roadblocks, particularly in developing countries like India. Under this backdrop, this paper attempts to present an overview of the use and application RFID technology in India with a highlight on business-ecosystem for RFID in India. We also present various technical and non-technical challenges in the implementation of RFID in India.

The current manufacturers have generated tremendous amount of digitized product data to efficiently share and exchange it with other stakeholders or various software systems for product development. The digitized product data is a valuable asset for manufacturers, and has a potential to support high level strategic decision makings needed at many stages in product development. However, the lack of studies on extraction of key performance indicators(KPIs) from product data management(PDM) databases has prohibited manufacturers to use the product data to support the decision makings. Therefore this paper examines a possibility of an architecture that supports KPIs for evaluation of product development performances, by applying multidimensional product data model and on-line analytic processing(OLAP) to operational databases of product data management. To validate the architecture, the paper provides a prototype product data management system and OLAP applications that implement the multidimensional product data model and analytic processing.

Information System is a critical success factor for overcoming the limitations of asset and capacity of Small and Medium Enterprises (SME), and for acquiring competitiveness. Although, the rate of adopting information system by SME has grown, the rate of its utilization has been stagnant. The purpose of this study is to identify the influencing factors that increase SME's information system utilization. We identify perception of strategic value, supplier's support capacity, and organizational characteristic by examining previous researches on information system utilization by SMEs, and verify their the influencing relationship with the information system utilization. This study verifies the research model and hypothesis using structural model. A date-set of 1209 samples from a survey on employees in charge of information system of SME was applied in verifying the research hypothesis. The result of this study shows that the information system utilization influences perception of strategic value and support of supply company, and partly, the structural characteristics. This study presents directions to establish strategy and policy making, and theoretically presents core factors of SME's information system utilization.

The purpose of this research is to examine the impact of information risk on the Cost of Equity (COE) and whether the risk of a stock price crash mediates the relation between information risk and COE. To test the dynamic nature of the proposed model, the two-step system GMM dynamic panel estimators are applied to all the non-financial firms listed on the Pakistan Stock Exchange (PSX) from 2007- 2018. The results of this study show that all three types of information risk, as well as the risk of the share price crash, increases the COE. The crash risk strengthens the impact of information risk on the COE. Moreover, these three information risks are correlated with each other and an increase in information quality reduces the effect of asymmetric information and improves the investor interpreting ability, while an increase in private information decreases the transparency. The finding is crucial for asset pricing, portfolio management, and information disclosure. This study contributes to the literature by providing novel findings on the impact of three different types of information risk, i.e. private information, quality of information, and transparency of information on the COE as well as whether crash risk mediates the relationship.

The product lifecycle of a marine vessel can be classified into the design-production, operation-maintenance, and disposal phases. During the operation and maintenance phase, status data should be gathered from the major machinery and instruments installed on the marine vessel in order to perform efficient maintenance work. Although a PLM (product lifecycle management) system can manage the product information during the design and assembly stage, a PLM based on asset management technology is more appropriate for product information management during the operation stage. Product embedded information devices (PEIDs) are suggested for gathering real-time maintenance information during the operation and maintenance lifecycle. A PEID allows PLM to provide the capability of offering active information exchange between the lifecycle management system and equipment. This study designed a PEID to effectively obtain information and interact with a PLM system. It consists of sensors, wireless communication, and a micro-processor, which allow it to accumulate status data on the PLM system. The embedded information device and PLM enable the seamless information flow, tracking, and updating of MRO (maintenance repair and overhaul) information for a product throughout the middle of the product lifecycle.

사이버 보안을 위한 활동인 '위험관리(Risk management)'와 '보안관제(security monitoring)' 업무는 미래에 발생할 보안 위협에 대비하고 보안 사고를 최소화 하는 활동이라는 점에서 깊은 상관관계를 가지고 있다. 또한 위험관리와 보안관제 분야 모두 관리자에게 시각적으로 그 정보자산에 대한 위협을 보여주는 패턴 모델을 적용하는 것이 효과적이다. 검증받은 패턴모델로는 전통적인 품질관리 분야에서 오랫동안 사용되어온 '관리도'(control chart)모델이 존재하지만 정보시스템의 사이버 위험관리와 보안관제에서의 활용은 부족하다. 이에 본 논문에서는 위험관리와 보안관제 시스템을 통합한 사이버 SRM(Security Risk Monitoring)시스템을 설계하였다. SRM은 '관리도'의 패턴을 이용한 '보안대책' (security control)의 적용 전략을 제시한다. 보안대책은 기존의 표준화된 보안대책 집합인 ISMS, NIST SP 800-53, CC를 통합적으로 적용하였다. 이를 활용하여 2014~2018년 까지 4년간 우리나라사이버위기 경보동향을 분석하였고 이는 향후 보다 유연한 보안대책 수립을 가능하게 한다.
