Recently, both the integration of product data during design and production and the effective management of information during full lifecycles have attracted attention from shipyards and ship owners as a result of recycling regulations and a desire for efficient operations. Generally, PLM (Product Lifecycle Management) supports a collaborative environment during the BOL (Beginning of Life) stage, while an ALM (Asset Lifecycle Management) system provides all of the information required to maintain, overhaul, and discard/recycle all or part of a vessel during the MOL (Middle of Life) and EOL (End of Life) stages. The main goal of this paper is to suggest the fundamental configuration of a PALM (Product Asset Lifecylce Management) system and a method that can be used to utilize a marine vessel's lifecycle information during the MOL, emphasizing the maintenance information during the middle of life. The authors also suggest a PALM system configuration in which lifecycle information can be collected by a PEID (Product Embedded Information Device) integrating a microcomputer, sensors, and wireless network communication. Through a prototype PALM system, the suggested features and PALM system configuration are implemented.

EPC를 탑재한 RFID 형태의 스마트객체를 이용한 물류 시스템을 구축하기 위해서는 시스템 구성 요소간의 거래에 필수적인 RFID 객체의 PML 데이터를 표현하고 검색요구에 대응하는 RFID 정보서비스의 설계 및 관리가 매우 중요하다. EPC기반 RPID 정보서비스는 네트워크상의 정보시스템들에 보안과 운영의 이유로 분산되어 있는 RFID 객체 정보들을 검색하여 사용자가 요구하는 결과를 반환하는 역할을 담당한다. 하지만 RFID 객체 정보의 표준화된 표현과 처리, 그리고 분산처리로 인한 통신량과 처리시간 과다의 문제가 존재한다. 이에 대해서 본 연구는 물류시스템의 PML 데이터의 표현 및 사용, 검색패턴을 분석하고, 분석 결과를 기반으로 미들웨어를 이용하는 분산형 RFID 객체 데이터 관리 및 RFID 객체 정보서비스 구조를 설계하고 제시하였다. 단일형 및 통합형 RFID 정보서비스 구조를 제시하였다.

Typical multi-tier client/server architecture includes various and complex objects scattered around the network. Those objects must be clearly identified and designed. Then, their interface must be well-defined so that the integration can be done without major difficulties. This paper presents an application framework to increase reuse and to accomplish architectural simplicity in information systems development. Each component of the architecture is identified and designed. The proposed architecture of the application framework provides the fundamental structure for developing individual functions of an information system. Resulting architectural simplicity achieves effective and efficient maintenance throughout the lifecycle of the information systems. Although the framework aims at the reuse within a project, the productivity of information systems development across projects will be greatly improved eventually. Cases are discussed to evaluate the practicality of the architecture presented.

최근 IT 아키텍처에 대한 연구와 논의가 국내 외적으로 공공부문 및 사부문에서 주요 관심사항으로 대두되고 있다. 발전단계 별로 고찰해 볼때 IT 아키텍처는 혁신적인 새로운 개념이라기보다는 점진적으로 진화한 개념으로 보는 것이 타당할 것으로 보인다. 사례 연구로서 미국의 정부 조직인 FEMA의 IT 아키텍처와 이에 상응하는 국내 B부처의 안전관리 시스템 구축을 위한 ISP를 비교한 결과 태스크나 작업산출물 측면에서 큰 차이를 보이지 않았다. 이 연구의 결론 부분에서 IT 아키텍처 구축 시에 필요한 요인 및 정책적 함의를 논의하였다.

정보자원에 대한 투자가 증가하면서 비용절감을 도모할 수 있는 클라우드 컴퓨팅 서비스에 대한 관심이 증가하고 있다. 그러나 클라우드 컴퓨팅은 경제적 이득이라는 장점과 함께 물리적으로 외부에 위치한 정보자원을 활용함에 의해 정보자산 통제와 정보보호의 취약점을 증가시킨다는 단점을 지니고 있다. 이에 본 연구에서는 클라우드 서비스의 고유속성으로 인한 새로운 취약점을 포함하여 클라우드 컴퓨팅의 취약점 도출과 클라우드 컴퓨팅의 취약점 통제항목을 도출한 후, 취약점과 통제항목간의 매핑을 통하여 관리되고 있지 않은 취약점을 파악하여 클라우드 컴퓨팅의 위험요인을 제시하였다.

This research proposes the composition logic of an Active Learning Environment (ALE), to enable discovery by learning through experience, whilst increasing knowledge about modern architectural heritage. Linking information to the historical heritage using Information and Communication Technology (ICT) helps to overcome the limits of previous learning methods, by providing rich learning resources on site. Existing field trips of cultural heritages are created to impart limited experience content from web resources, or receive content at a specific place through humanities Geographic Information System (GIS). Therefore, on the basis of the blended space theory, an augmented space experience method for overcoming these shortages was composed. An ALE space framework is proposed to enable discovery through learning in an expanded space. The operation of ALE space is needed to create full coordination, such as a Content Management System (CMS). It involves a relation network to provide knowledge to the rule engine of the CMS. The application is represented with the Deoksugung Palace Seokjojeon hall example, by describing a user experience scenario.

Today the system of higher education needs significant reforms. Intellectualization of the educational process in HEIs aims to improve the quality of educational services. Intellectual information technologies are information technologies that help a person to accelerate the analysis of the political, economic, social, and technical situation, as well as the synthesis of management decisions. The basis for their mastery is information and communication technologies. The purpose of the research work is to identify the relationship between the introduction of information and communication technologies and the increase in the level of intellectualization of higher education. The article substantiates the expediency of introducing information and communication technologies in order to improve the intellectualization of the educational process in higher education. An empirical study of the variables that characterize the level of intellectualization of higher education through the proposed techniques has been conducted. The tendencies characteristic of pedagogical conditions of implementation of information and communication model in the educational process were revealed. It is proved that the level of intellectualization of higher education depends on the implemented pedagogical conditions. The effectiveness of the proposed information and communication model is also confirmed. Given the data obtained during the study and the low constraints that may affect the results of further research on this issue should focus on the study of other variables that characterize the state of intellectualization of the educational process.

InfiniBand is a switched-fabric architecture for next generation I/O systems and data centers. The InfiniBand Architecture (IBA) promises to replace bus-based architectures, such as PCI, with a switched-based fabric whose benefits include higher performance, higher RAS (reliability, availability, scalability), and the ability to create modular networks of servers and shared I/O devices. The switched-fabric InfiniBand consists of InfiniBand subnets with channel adapters, switches, and routers. In order to fully grasp the operational characteristics of InfiniBand architecture (IBA) and use them in ongoing design specification, simulation of subnet management of IBA is inevitable. In this paper, thus, we implement an IBA simulator and test some practical sample networks using it. The simulator shows the flow of operation by which the correctness and effectiveness of the system can be verified.

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.
