This study introduces an overall framework for RFID applications in product lifecycle management(PLM). PLM is a new strategic approach to manage product related information efficiently over the whole product lifecycle. Recently, with emerging technologies such as radio frequency identification(RFID), global positioning system(GPS), and wireless communication, PLM provides a new environment that enables us to gather and analyze product lifecycle information, and make decisions on several issues without spatial and temporal constrains. However, a PLM system just provides us with new opportunities to gain the PLM system, first and foremost, it is necessary to look into its overall framework in the viewpoint of hardware, software, and business model. For this purpose, in this study, first, we introduce the technical framework of the new PLM environment with the concept of extended RFID system, called product embedded information device(PEID). Then, for each lifecycle phase such as beginning of life(BOL), middle of life(MOL), and end of life(EOL), we explore several research problems that become highlighted under the new PLM environment.

With the advances in Information Technology (IT), users can download or stream copyrighted works, such as videos, music, and webtoons, at their convenience. Thus, the frequency of use of copyrighted works has increased. Consequently, the number of unauthorized copies and sharing of copyrighted works has also increased. Monitoring is being conducted on sites suspected of conducting copyright infringement activities to reduce copyright holders' damage due to unauthorized sharing of copyrighted works. However, suspected copyright infringement sites respond by changing their domains or blocking access requests. Although research has been conducted for improving the effectiveness of suspected copyright infringement site detection by defining suspected copyright infringement sites' response techniques as a lifecycle step, there is a paucity of studies on automation techniques for lifecycle detection. This has reduced the accuracy of lifecycle step detection on suspected copyright infringement sites, which change domains and lifecycle steps in a short period of time. Thus, in this paper, an automated detection technique for suspected copyright infringement sites is proposed for efficient detection and response to suspected copyright infringement sites. Using our proposed technique, the response to each lifecycle step can be effectively conducted by automatically detecting the lifecycle step.

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.

In order to reduce the cost of software maintenance including software modification, we suggest the object oriented program with checking the version of application program using the Java language and the technique of executing the downloaded application program via network using the application manager. In order to change the traditional scheduler to the application manager we have adopted the Xlet concept in the nuclear fields using the network. In usual Xlet means a Java application that runs on the digital television receiver. The Java TV Application Program Interface(API) defines an application model called the Xlet application lifecycle. Java applications that use this lifecycle model are called Xlets. The Xlet application lifecycle is compatible with the existing application environment and virtual machine technology. The Xlet application lifecycle model defines the dialog(protocol) between an Xlet and its environment

As the market becomes increasingly globalized and competition among companies increases in severity, various specialized organizations are participating across the process plant lifecycle, including the stages of design, construction, operation and maintenance, and dismantlement, in order to ensure efficiency and elevate competitiveness. In this regard, it is an important technical issue to develop services or information systems for sharing process plant data among participating organizations. ISO 15926 is an international standard for integration of lifecycle data for process plants including oil and gas facilities. ISO 15926 Part 7, a part of the ISO 15926 standard, specifies an implementation method called a facade that uses Web Services and ontology technologies for constructing plant data repositories and related services, with the aim of sharing lifecycle data of process plants. This paper discusses the ISO 15926-based prototype facade implemented for storing equipment data of nuclear power plants and servicing the data to interested organizations.

The rapid growth of communication and globalization has changed the software engineering process. Security has become a crucial component of any software system. However, software developers often lack the knowledge and skills needed to develop secure software. Clearly, the creation of secure software requires more than simply mandating the use of a secure software development lifecycle; the components produced by each stage of the lifecycle must be correctly implemented for the resulting system to achieve its intended goals. This study demonstrates that a more effective approach to the development of secure software can result from the integration of carefully selected security patterns into appropriate stages of the software development lifecycle to ensure that security designs are correctly implemented. The goal of this study is to provide developers with an Integrated Security Development Framework (ISDF) that can assist them in building more secure software.
