Although domestic research funding organizations require patented technologies as an outcome of financial aids, they have much difficulty in evaluating qualitative value of the patented technology due to lack of systematic methods. Especially, because citation data is not essential to patent application in Korea, it is very difficult to evaluate a patent using the incomplete citation data. This study proposes a method for evaluating technology importance of a patent when there is no or insufficient citation data in patents. The technology importance of a patent can be evaluated objectively and quantitatively by the proposed method which consists of 5 steps such as selection of a target patent, collection of related patents, preparation of key word vector, clustering patents, and technological importance assessment. The method was applied to a patent on 'user identification method for payment using mobile terminal' in order to evaluate technology importance and demonstrate how the method works.

The position of sensors generally affects coverage, communication costs, and resource management of surveillance sensor networks. Thus we are required to place a sensor in the best location. However, it is difficult to consider that terrain and climate factors influencing sensors when sensor nodes are deployed in the real world, such as a mountain area or a downtown area. We therefore require a sensor deployment method for detecting effectively targets of interest in terms of surveillance area coverage in such environment. Thus in this paper, we analyze various environmental factors related to sensor deployment, and quantify these factors to use when we deploy sensors. By considering these quantified factors, we propose a practical and effective method for deploying sensors in terms of sensing coverage. We also demonstrate the propriety of the proposed method through implementing a sensor deployment management system according to the method.

Engineering structures including civil infrastructures require a life-cycle cost and benefit during their service lives. The service life of a structure can be extended through appropriate inspection and maintenance actions. In general, this service life extension requires more life-cycle cost and cumulative benefit. For this reason, structure managers need to make a rational decision regarding the service life management considering both the cost and benefit simultaneously. In this paper, the probabilistic decision tool to determine the optimal service life based on cost-benefit analysis is presented. This decision tool requires an estimation of the time-dependent effective cost-benefit under uncertainty to formulate the optimization problem. The effective cost-benefit is expressed by the difference between the cumulative benefit and life-cycle cost of a deteriorating structure over time. The objective of the optimization problem is maximizing the effective cost-benefit, and the associated solutions are the optimal service life and maintenance interventions. The decision tool presented in this paper can be applied to any deteriorating engineering structure.

As the competition between companies are deepened, the number of companies adopting six sigma principles, which is one of the innovative management strategies, are increasing. According to this trend, the changes in both strategies and methodologies of six sigma are continuous. However, the evaluations and the management principles included in the process after the six sigma applications are insufficient, and the cooperation between the parties in the company is also not enough because the application process of six sigma is too complex and not efficient. In order to solve this problem, a research for developing the methodology which can learn about and do six sigma applications is so necessary, specifically for expanding the six sigma applications and introducing the participation of all company members. The purpose of this study, therefore, was to develop and present more efficient Six Sigma applied process by reducing the existing unnecessary steps in improvement one, by applying the examination method of wasteful elements on the potential factors, through analyzing the Six Sigma DMAIC applied case in the construction industry. The result of those application showed that the detection of potential factors using wasting elements was possible in measurement step and that it was possible for the improved process with reduced steps compared to existing process while to remain the outcomes. It is considered that the performance rate of Six Sigma project will be improved significantly because the reduction in the improvement step does not affect the improvement effect within the whole Six Sigma project.

It is essential suity management and standardized asset analysis for telecommunication networks, however existing risk analysis methods and tools are not enough to give shape of the method to evaluate value and asset. they only support asset classification schemes. Moreover, since the existing asset classification schemes are to evaluate comprehensive general risk, they are not appropriate for being applied telecommunication networks and they can´t offer any solutions to an evaluator´s subjectivity problem. In this paper, to solve these problems, we introduce the standardized definition of asset evaluation model new asset classification scheme, two-dimensional asset process classification scheme to consider business process and asset, various evaluation standards for quantitative value and qualitative evaluation. To settle an valuator´s subjectivity problem, we proposed $\beta$-distribution Delphi method.

Agile development methods regards an interaction among software developers, operating softwares, and cooperation with customers as its main value. Most of the developing processes undergo a procedure called tailoring to meet the relevant project. Yet, in reality, projects run in disorder due to their overlap with other methods and management processes. As a result, the advantages of agile process cannot be fully used. So, the information system audit has an important role to detect these problems and improve the qualities of agile application projects. Also, researches should be conducted on Agile-based Iformation System Audit Model in order to enhance the effectiveness of agile projects. This paper suggests a model for an information system audit that applied agile developing methods. This model proposes audit domains and check lists for agile-based information system. In order to verify the suitability of the suggested model, more than 89.3% of the checklists were verified as suitable in all domains.

The Ministry of National Defense has developed MND-AF and Defense-CBD methodology to make the integration and management of standardization effective through enhancing the interoperability and reusability of information systems. Yet no explicit guidelines or procedures have not been developed for the applying range and mutual relationship of the artifacts between MND-AF and Defense-CBD methodology. Thus, the development time is unnecessarily extended and budget also is increasing because both methodologies produce the artifacts respectively. This paper presents a reusability enhancement scheme for producing MND-AF artifacts according to Defense-CBD process by analyzing artifacts of two methodology les at each element level, so that it will reduce the overhead of producing the artifacts and enhance the completeness of the artifacts. In result, in the case of applying Defense-CBD methodology for developing a information system34 artifacts out of 37 MND-AF artifacts can be reusable.

The choice of appropriate methodologies has always been a challenge. It is time to find obstacles when Extreme programming(XP) is adopted. In this paper, we invest status of adoption of XP methodology which is more popularized. We survey how the Values and the Practices of XP can be adopted to developer in terms of the usefulness and the easy of use of XP. As a result, it is regarded as a successful one in improving quality and timeliness through software development process. The Values and Practices, a basis of XP philosophy and its adoption, could be easily accomplished, but other elements - communication, feedback. collective ownership, pair programming, simple design and customer participation - which do not depend on technology could not be accomplished easily. To introduce XP easily in the creative and labor intensive software development fields, the managers and the educators have to make efforts to apply these Values and Practices based on humane characteristics as well as technical elements.

NFC(Near Field Communication),the short-distance communication protocol, is a technology with a wide range of application applied to smart phones. In particular, many of the services in NFC environments utilize users' privacy information. Privacy information used in such services leads to new vulnerability due to the very features of NFC technology and of NFC devices represented by smart phones. Therefore, the purpose of this study is to suggest a methodology that analyzes privacy vulnerability resulting from a NFC environments in technological, managerial and institutional aspects and a methodology aimed to establish a countermeasure to augment them. Also, this study will suggest vulnerability and countermeasures accordingly in domestic NFC service drawn out through the above methodologies and a countermeasure to improve the vulnerability. It is expected that various safe countermeasures for privacy protection in NFC environments will be established through the suggested methodologies.
