It is highly required to evaluate the economic value of technology in many decision making of the technology management area, for example, technology acquisition, transfer, and investments. Also evaluating the performance of R&D objectively is very important subject in the public side. So, developing the objective technology evaluation system has much usefulness in practice. In many studies, the patent information has been suggested to the valid measurement for evaluation of technology. The purpose of this study is to explore the validity of patent information as a measurement of technology evaluation.

The concern and request of high-quality software has been increased according to the rapid transition of society to information-oriented era. Therefore activities of software quality management are regarded as serious as the activities of software development. Moreover, stakeholder of software may have various views of software quality. And some quality characteristics need to be managed with priorities in Software Development Life Cycle (SDLC). Hence we recognized that weights of quality characteristics might be useful to improve efficiency of quality management activities. However, this topic has not actively issued because its necessity and effectiveness has been ignored. This paper presents a technique to decide weights of software quality characteristics in SDLC. It is based on ISO/IEC 9126 which is the standard for software product quality. It is accomplished by questionnaires intended for stakeholder in software development and weight analysis through AHP (Analytic Hierarchical Process) method. Accordingly, it can select quality characteristics by weight in SDLC. And then it helps us to acquire high duality software through measuring software quality quantitatively and expecting the quality after completion of software development.

This study examines the value-relevance of accruals and discretionary accruals. Also, by examining the effects of the corporate life-cycle on these relationship, this study is able to provide evidence of the value-relevance of accruals and discretionary accruals measures in the economic context of life-cycle theory. This study uses results based on life-cycle classification methods developed by Anthony and Ramesh(1992), adjust Jones model and Dechow Dechev(2002) model. We classify firms using individuals variables(sales growth, capital expenditure growth, employee growth) and then use a composite score obtained from all variables for classification. Our sample consists of 272 firms listed in the Korean Stock Exchange during 14 years(1996-2009). Our final sample for regression variables consists of 2,448 firm-year observations. This evidence implies that the value-relevance of accruals and discretionary accruals in the growth and mature stage can have positive impact on the price but in the decline the value-relevance of accruals and discretionary accruals can have negative impact on the price. The results mean that discretionary accruals communicate managements' private information in the growth stage, but. earnings management in the decline stage. The results of this study suggest that corporate life cycle stages influence the value-relevance of accruals and discretionary accruals measures.

양질의 소프트웨어제품과 서비스를 생산하는 방법은 우수한 선례를 답습하거나, 성공한 선례를 해당 응용업무에 맞도록 발전시키는 것이다. 즉 프로세스들의 모임인 소프트웨어 프로세스를 각각의 소프트웨어 서비스와 시스템의 개발목적에 부합하도록 정의하는 것이다. 프로세스 모임은 정보화사업의 포괄적 관리가 가능하게하며, 사업제기부서가 소프트웨어 시스템에 대한 전반적인 의무와 책임을 갖게 하며, 정보화사업 감리에 있어서 감리 목표 정립과 감리의 시행을 명확하게 한다. 소프트웨어 서비스 및 시스템 개발에 있어서 적합한 프로세스의 모임을 목표프로세스 프로파일(Target Process Profile) 이라고 명명하였다. TPP을 정의함에 있어서는 정의할 대상시스템의 성능과 시스템의 효과성이 어느 정도 가시화되는 여건에서, 소프트웨어 서비스 및 시스템의 수명주기 목표, 수명주기 아키텍쳐 및 수명주기 계획을 도출한다. 즉 아키텍쳐 접근방법, 소프트웨어프로세스의 정착, 및 국제표준의 프로세스에서의 프로세스 모임규칙을 근간으로 하여 TPP의 프레임워크(Framework)을 시안을 작성하였다. 소프트웨어공학의 발전과정에서 프로세스 능력의 성숙도 기준으로 프로세스 모임을 이룬것에 추가하여, 논자는 ISO/IEC 15504 TR 프로세스간의 전후관계에서 TPP을 위한 작업산출물 도출방법을 정의하였다. TPP에 의한 정보화추진은 정보화시대에서 소프트웨어 품질 및 가격에서 경쟁력을 가져오는 요인이 될 것이다.

This study is intend to analyze the cited patent life time of US patent data via more objective way. It is based on exploratory approach which is one of various methods for technology forecasting. The life spans of cited patents of specific technological field are deduced from using informetric analysis of USPA database of KISTI, which is composed of US patent data covered from 1972 to present. The statistics of the results may help to estimate the economic life span of the specific technological area for technology valuation.

Building Information Modeling (BIM) is the process of integrating and re-using information generated and used throughout the lifecycle of a building. BIM may not be very different from other management methods in that it aims to minimize the economic loss and maximize the profit by designing, building, and maintaining a building better, faster, yet cheaper. The major difference between BIM and other methods is that BIM approaches the goal from a system point of view whereas other methods generally approaches the goal from a business management point of view. Since a project cannot succeed without considering both systematic and managerial aspects of a project, the line has been blurred these days. This paper explores a historical background of BIM and discusses the key technologies for successful implementation of BIM.

The e-business strategies ultimately Pursue creating the maximal value for customers through the competitive advantages and business opportunities newly created on the basis of information technologies. For the realization of e-business strategies, the successful implementation and operation of e-business system must be the crucial activities in and out of an organization. Therefore, in physical world, there were lots of interests that what kind of key factors can lead the success of e-business system. Moreover, in the field of academia also, there have been many research results for investigating and finding out the key success factors for e-business system. However, the perceptual level of the significance of key success factors that organization members perceive can be changed over each phase of system life cycle such phases as introduction, growth, maturity, and decline. This study investigated that there might be significant differences in the perceptual level regarding importance of success factors among phases of system life cycle.

So far, the importance of informatization, as well as investment into it, has been growing steadily. Due to the uncertainties and risks in adopting information technologies, systematic decision-making is definitely needed in investing in a large scale information system. Based on the existing theories about the economic life span of information systems and in consideration of the actual cost involved in the adoption and operation of the systems by the financial institutions in Korea, this study presents the optimal economic life span for all types of information systems in terms of the economic cost and generalizes the optimal life span. The ultimate purpose of this study is to develop a model that could be used in anticipating the timing of economic replacement of the information system of the same type and making decisions on IT investment.
