Ontology is an indispensable component in intelligent and semantic processing of knowledge and information, such as in semantic web. However, ontology construction requires vast amount of data collection and arduous efforts in processing these un-structured data. This study proposed a methodology to automatically construct and generate ontologies from Sejong Electronic Dictionary. As Sejong Electronic Dictionary is structured in XML format, it can be processed automatically by computer programmed tools into an OWL(Web Ontology Language)-based ontologies as specified in W3C . This paper presents the process and concrete application of this methodology.

There are many limitations in applying agile methodology to projects so far. In fact, projects overlap with other development methodologies and management processes, resulting in confusing progress, while there are often cases where the benefits of agile cannot be embraced due to a lack of understanding of agile processes and the organization's inability to adapt to change. It is an important role of information system development to improve the quality of agile application projects by discovering the problems and improvements in these cases. In this paper, we analyze the differences between existing development and project management methods and agile, and analyze agile processes. The optimal agile methodology was proposed by analyzing and applying methodologies established and applied mainly by large domestic development companies. In addition, the effectiveness was verified through a questionnaire of IT experts, and the result of the questionnaire was verified to be 4.75 points on a 5-point scale.

ESD(Electro-Static Discharge) 보호회로용 nMOSFET에 대하여 TCAD 시뮬레이션을 수행하기 위한 새로운 parameter calibration 방법론을 제안하였다. ESD 특성 측정방법의 하나인 TLP (Transmission Line Pulsing)측정을 이용하는 경우, ESD 입력에 대하여 시간변화에 따른 소자의 특성을 파악할 수 있기 때문에 최근 많은 관심을 받고 있다. 본 논문에서는 TLP 측정의 해석방법과 TCAD simulation, 그리고 parameter calibration의 방법론을 제시하였다.

In this paper, we present the methodology of performance testing for web based university resource planning systems. The methodology contains an adequate procedure and workload assessment method. We execute real performance testing to the university resource system during system test stage. To verify the adequacy of the methodology, We compare the result between testing system's hardware utilization and operating system's. The result is nearly the same. Empirical experiments are also shown.

In this paper, we dealt with substantial asset analysis methodology applied to two-dimensional asset classification and qualitative evaluation method according to the business process. Most of the existent risk analysis methodology and tools presented classification by asset type and physical evaluation by a quantitative method. We focused our research on qualitative evaluation with 2-dimensional asset classification. It converts from quantitative asset value with purchase cost, recovery and exchange cost, etc. to qualitative evaluation considering specific factors related to the business process. In the first phase, we classified the IT assets into tangible and intangible assets, including human and information data asset, and evaluated their value. Then, we converted the quantitative asset value to the qualitative asset value using a conversion standard table. In the second phase, we reclassified the assets using 2-dimensional classification factors reflecting the business process, and applied weight to the first evaluation results. This method is to consider the organization characteristics, IT asset structure scheme and business process. Therefore, we can evaluate the concrete and substantial asset value corresponding to the organization business process, even if they are the same asset type.

This study was designed to validate Spreading Activation Theory (SAT) for an evaluation methodology for menu structure through Eye-Tracking approach. When a visual search is on the way, more eye fixations and time are necessary to visually process complex and vague area. From the aspect of recognition, well-designed menu structures were hypothesized to have fewer numbers of fixations and shorter duration because well-designed menu structures reflecting the users' mental model would be well matched with the product's menu structure, resulting in reducing the number of fixations and duration time. The results show that the shorter reaction times for SAT had significantly fewer numbers of fixation and shorter duration time as the hypothesis for this study stated. In conclusion, SAT was proved to be an effective evaluation methodology for menu structure with the eye tracking equipment. In addition, using SAT instead of the real performance experiment would be useful for designing user-centered systems and convenient information structures because SAT was proven to be the theoretical background for design and evaluation of menu structures.

In this paper we propose the methodology for 3D background image construction in computer games. This methodology was developed based on TIP (Tour Into the Picture) using a vanishing line Proposed by Kang et at. The methodology Proposed in this study can simply implement a 3D background for a computer game with a background model which is very complex or based on a real picture. Compared to the graphics technologies generally used, the proposed methodology does not need the process of modeling elaborate 3D information of a background, and hence can display the background even on a low grade personal computer using a small reference image. TIP technology was successfully applied to the implementation of a background model for a computer game and was found to be appropriate especially for real time games.

Windborne debris is a major cause of structural damage during severe windstorms and hurricanes owing to its direct impact on building envelopes as well as to the 'chain reaction' failure mechanism it induces by interacting with wind pressure damage. Estimation of debris risk is an important component in evaluating wind damage risk to residential developments. A debris risk model developed by the authors enables one to analytically aggregate damage threats to a building from different types of debris originating from neighboring buildings. This model is extended herein to a general debris risk analysis methodology that is then incorporated into a vulnerability model accounting for the temporal evolution of the interaction between pressure damage and debris damage during storm passage. The current paper (Part I) introduces the debris risk analysis methodology, establishing the mathematical modeling framework. Stochastic models are proposed to estimate the probability distributions of debris trajectory parameters used in the method. It is shown that model statistics can be estimated from available information from wind-tunnel experiments and post-damage surveys. The incorporation of the methodology into vulnerability modeling is described in Part II.

소프트웨어 개발방법론은 새로운 소프트웨어를 개발하는데 가장 효율적인 개발 방법과 관리 방법 등을 제시하고 있다. 그러나 소프트웨어 개발방법론은 많은 비용과 시간을 필요로 하고 있으며, 소프트웨어공학 전문가를 필요로 하고 있다. 이러한 이유로 필요성은 인정받고 있으나 대규모 소프트웨어에서만 적용되는 문제점들을 안고 있다. 본 논문에서는 현재 많이 사용되고 있는 소프트웨어 개발방법론을 전문가 없이 소규모 소프트웨어를 개발하는데 적용할 수 있도록 반드시 필요한 단위 일(Task)을 선별하고 대안으로 정의하여 AHP(Analytic Hierarchy Process) 기법을 통해 대안에 대한 적합도를 평가하였다. 이를 통해 중소기업에서도 평가된 소프트웨어 개발방법론을 사용하여 소프트웨어를 효율적으로 개발하고 관리할 수 있다.
