In order to satisfy the high need for technology valuation, various technology valuation methods have been developed. However the need to develop a new technology valuation method considering the technology characteristics, technology valuation objective, and technology valuation environments has been increasing. So far the technology valuation mehtods have been developed based on technology valuation experts' domain knowledge without applying systematic design methodology. In this paper the process that applies Axiomatic Design principles as a design methodology to the technology valuation methodology design is described. The design consists of technology valuation process design and technology valuation content design. The Axiomatic Design approach introduced in this paper can be used as a systematic technology valuation design tool considering various technology characteristics and technology valuation objectives and also as an evaluation tool of traditional technology methods.

With the rising social interest in the sustainable life, demands are growing for Hanok, as a viable alternative to modernized architecture of Western origin. However, even Hanok is gaining popularity among the general public, its design and construction are still a minor practice. Aiming to build an information system of Hanok, this research proposes a new design process for traditional architecture, utilizing a parametric design methodology. This process, based on the understanding of tectonic joints and spatial composition of our traditional architecture, defines a parametric relationship among the structural elements that compose Hanok. The research uses Gehry Technologies' Digital Project and Autodesk Revit Architecture to apply a concurrent parametric design methodology, approaching the project in both bottom-up and top-down to present a new design process for Hanok elements.

기업간 전자상거래에서 조합경매(combinational auction)에 대한 관심이 증가함에 따라 다양한 조합경매 유형이 제시되고 있다. 조합경매의 실용성에 대한 잠재적 중요성을 고려할 때, 다양한 조합경매모델을 지원할 수 있는 통합적이고 체계적인 설계방법이 필요하다. 조합경매 설계에 대한 기존 연구들은 조합경매에 관한 일부 설계요소들에 대해서만 제시하였으며, 부분적인 측면에서 연구가 진행되어 전체적인 관점에서의 설계체계가 제시되지 않았다. 이에 본 연구에서는 조합경매모형에 대한 설계의 토대가 될 수 있는 체계적인 틀을 제시하고자 한다. 설계단계는 크게 아키텍처, 프로토콜, 거래전략 설계 과정으로 이루어진다. 설계과정에서 아키텍처 유형과 프로세스 유형을 분류하고 이들의 조합으로 나타나는 메커니즘 유형을 분류하여 조합경매 모형에 대한 분류체계를 제시하였다. 또한, 거래전략 설계 단계에서는, 거래 당사자들의 다양한 전략을 반영하여 최적의 거래대상을 선정하는 최적화 모형에 기반한 효과적인 조합경매모형 설계방법을 제안하였다. 마지막으로, 본 방법론에 기반하여 새로운 조합경매 모형인 다자간 일반 조합경매 시장에 대한 설계과정을 예시함으로써, 본 방법론의 적용 가능성을 제시하였다.

The recent sudden increase of big data has characteristics such as continuous generation of data, large amount, and unstructured format. The existing relational database technologies are inadequate to handle such big data due to the limited processing speed and the significant storage expansion cost. Current implemented solutions are mainly based on relational database that are no longer adapted to these data volume. NoSQL solutions allow us to consider new approaches for data warehousing, especially from the multidimensional data management point of view. In this paper, we develop and propose the integrated design methodology based on MongoDB for big data applications. The proposed methodology is more scalable than the existing methodology, so it is easy to handle big data.

Structural qualification plan (SQP) for aerospace vehicle is based on material certification methodology, which must be approved by certification authority. It is internationally required to use of statistically based material allowables to design aerospace vehicles with aerospace materials. In order to comply with this regulation, it is necessary to establish relatively large amount of database, which increases test costs and time. Recently NASA/FAA develop the new methodology which results in cost, time, and risk reduction, and satisfies the regulation at the same time. This paper summarizes the certification methodology of materials system as a part of structural qualification plan (SQP) of aerospace vehicles and also thermal management of the vehicle system, like thermal protection materials system and thermally conductive material system. Materials design allowable was determined using this method for a carbon/epoxy composite material.

In this paper, a Performance Based Design (PBD) approach is validated for multi-storey concentrically braced frame (CBF) systems. Direct Displacement Based Design (DDBD) procedure is used and validated by designing 4- and 12-storey CBF buildings. Nonlinear time history analysis (NLTHA) is used to check the performance of the design methodology by employing different accelerograms having displacement spectra matching the design displacement spectrum. Displacements and drifts obtained from NLTHA are found to fall within the design displacement limits used in the DDBD procedure. In NLTHA, both tension and compression members are found to be resisting the base shear, $F_b$, not only the tension members as assumed in the design methodology and suggested by Eurocode 8. This is the reason that the total $F_b$ in NLTHA is found to be greater than the design shear forces. Furthermore, it is found that the average of the maximum ductility values recorded from the time history analyses for the 4-and 12-storey buildings are close to the design ductility obtained from the DDBD methodology and ductility expressions established by several researchers. Moreover, the DDBD is compared to the Forced Based Design (FBD) methodology for CBFs. The comparison is carried out by designing 4 and 12-storey CBF buildings using both DDBD and FBD methodologies. The performance for both methodologies is verified using NLTHA. It is found that the $F_b$ from FBD is larger than $F_b$ obtained from DDBD. This leads to the use of larger sections for the structure designed by FBD to resist the lateral forces.

To develop high-quality software systems satisfying the customer's needs, user-centered design (UCD) process has been emphasized in the area of human-computer interaction. And component-based development (CBD) has been extensively studied to realize a systematic software reuse, thereby reducing the time-to-market and the development cost. Balanced integration of user-centered design process and CBD process will be a promising way for successful software construction, which effectively achieves three goals: the quality of software, the cost of software development, and the time-to-market. However, traditional CBD methodology seems to lack the concept of user-centered design process and the relevant methods. This paper proposes a way of incorporating user-centered design process into a CBD methodology. Firstly, this paper gives the brief introduction of UCD. Secondly, we explain typical UCD activities and methods along the phase of systems development lifecycle and propose the use of usability maturity model (UMM) for integrating UCD activities and methods with those of CBD methodology. Finally, as a case study, we describe the results of comparing the UCD activities to the activities of MaRMI-III, which has been developed as a CBD methodology at ETRI.

The purposes of the paper are to apply the axiomatic design methodology to the design of PBGA package with polyimide coating under hygrothermal loading in the IR soldering process and to suggest more reliable design conditions by stress analysis. The analysis model is a 256-pin perimeter Plastic Ball Grid Array (PBGA) package with the polyimide coating surrounding chip and above surface of BT-substrate. The polyimide coating is suggested to depress the maximum stresses occurred on the stress concentration positions. The axiomatic design methodology is proved to be useful to find the more reliable design conditions for PBGA package. Finally, the optimal values of design variables to depress the stress in the PBGA package are obtained.

The focus of this paper is on the development and implementation of a methodology for automated design of discrete structural systems. The research is aimed at utilizing Genetic Algorithms (GA) as an automated design tool. Several key enhancements are made to the simple GA in order to increase the efficiency, reliability and accuracy of the methodology for code-based design of structures. The AISC-ASD design code is used to illustrate the design methodology. Small as well as large-scale problems are solved. Simultaneous sizing, shape and topology optimal designs of structural framed systems subjected to static and dynamic loads are considered. Comparisons with results from prior publications and solution to new problems show that the enhancements made to the GA do indeed make the design system more efficient and robust.
