Corporate images are created inside the corporate and then peppered throughout the public such as consumers, communities, countries, etc. who are outside the corporate. Therefore, corporations express their corporate images through such visible images as CI, products, brands, advertisements, company buildings, etc. in order to form a favorable corporate image for the public. Therefore, many corporations have begun to express various visual factors in order to form their images. So, the purpose of this study is to determined the connectivities of corporate images and facade design of company buildings, and to elicit the findings of whether corporate images are applied to the facade design of company buildings, and of what expressive factors are applied to the design, if so. The conclusions are as follows: First, an examination of the degree that the characteristics of corporate images and design components of the facade design of company buildings have been expressed showed that corporations preferred the design of company buildings on which a lot of components have been expressed. Second, it also showed that they preferred determinants of the facade design of company buildings in the order of architectural factors > visual factors > decorative factors. Third, it indicated that the corporations on which the design components of the facade design of company buildings have been reflected most were in the order of C > B, D > A, E > G > F, J > H, I. Fourth, it further showed that most of the corporations have used curtain walls as materials of the facade design.

자동차 엔진을 포함한 구동계 및 흡배기계 소음의 특징은 차수 스펙트럼(order spectrum) 분석으로 파악할 수 있다. 기존의 선행 연구에서는 엔진의 1차 및 2차 점화주파수(firing frequency)와 관련된 차수성분이 차실내부 소음에 주요한 영향을 미치는 것으로 알려져 있다. 본 연구에서는 차수스펙트럼의 변환에 따른 차실내부 소음의 음질(쾌적감) 차이를 파악하고자 한다. 이를 위하여 6실린더 및 4실린더 가솔린 엔진을 가진 승용차의 차실 내부 소음을 측정하고, 이 소음에 적응형 디지털 필터(adaptive digital filter)를 적용하여 차수레벨을 가감하는 방법으로 수정한다. 쌍비교법을 이용한 청음실험을 통하여 원음 및 편집음의 음질 정도를 평가하고, 음질 향상을 위한 차수스펙트럼 변화 방향을 제시한다. 결과적으로 반-차수(half-order) 성분의 차수레벨 감소가 차실내부 소음의 쾌적감 향상에 영향을 주는 반면, 점화차수 레벨의 감소가 항상 음질에 긍정적인 영향을 주는 것은 아님을 파악하였다.

In this study, the supersonic panel flutter of doubly curved composite sandwich panels with variable thickness is considered under aerothermoelastic loading. Considering different radii of curvatures of the face sheets in this paper, the thickness of the core is a function of plane coordinates (x,y), which is unique. For the first time in the current model, the continuity conditions of the transverse shear stress, transverse normal stress and transverse normal stress gradient at the layer interfaces, as well as the conditions of zero transverse shear stresses on the upper and lower surfaces of the sandwich panel are satisfied. The formulation is based on an enhanced higher order sandwich panel theory and the vertical displacement component of the face sheets is assumed as a quadratic one, while a cubic pattern is used for the in-plane displacement components of the face sheets and the all displacement components of the core. The formulation is based on the von $K{\acute{a}}rm{\acute{a}}n$ nonlinear approximation, the one-dimensional Fourier equation of the heat conduction along the thickness direction, and the first-order piston theory. The equations of motion and boundary conditions are derived using the Hamilton principle and the results are validated by the latest results published in the literature.

In order to measure surface roughness profile, stylus type equipments are commonly used, but the stylus keeps contact with surface and damages specimens by its tip pressure. Therefore, optics based measurement systems are developed, and light phase interferometer, which is based on light interference phenomenon, is the most noticeable research. However, light interference based measurements require translation mechanisms of nano-meter order in order to generate phase differences or multiple focusing, thus the systems cannot satisfy the industrial need of on-the-machine and in-process measurement to achieve factory automation and productive enhancement. In this research, we focused light reflectance phenomenon rather than the light interference, because reflectance based method do not need translation mechanisms. However, the method cannot direct]y measure surface roughness profile, because reflected light consists of several components and thus it cannot supply surface height information with its original form. In order to overcome the demerit, we newly proposed an image processing based algorithm, which can separate reflected light components and conduct parameterization and reconstruction process with respect to surface height information, and then confirmed the reliability of proposed algorithm by experiment.

The purpose of this study is to examine the effect of logistics service quality and relationship orientation factors on customer satisfaction and loyalty in the electronic commerce context. Based on extensive review of relevant literature, nine components of logistics service quality(i.e. information quality, ordering procedures, ordering release quantities, timeliness, order accuracy, order quality, order condition, order discrepancy handling and personnel contact quality) and six components of relationship orientation(i.e. trust, bonding, communication, shared value, empathy and reciprocity) are introduced in this study. And a conceptual model is developed and five research hypotheses are empirically examined using structural equation modeling. The findings indicate that logistics service quality and relationship orientation are positively and significantly associated with customer satisfaction, and customer satisfaction is the antecedent variable of customer loyalty in the Internet Shopping Mall. In addition, a significant impact of logistics service quality on relationship orientation of the customer is revealed. Implications of these findings are discussed, and limitations of the study as well as further research directions are addressed.

컴포넌트 아키텍쳐 설계를 위하여 재사용 가능한 독립적인 비즈니스 컴포넌트의 식별은 컴포넌트 기반 시스템 구축을 위하여 가장 중요한 작업이다. 그러나 기존 컴포넌트 기반 개발 방법론들의 컴포넌트 시별 방법은 대다수 개발자의 직관과 경험에 의존하고 있다. 또한 개발자들에 의해서 식별된 컴포넌트가 보다 독립적으로 잘 정의되었는지 평가할 기준이 없다. 따라서 본 논문에서는 개발자의 직관과 경험에 의존하는 비즈니스 컴포넌트 식별의 어려운 점을 보완하기 위하여 비즈니스 컴포넌트 식별의 평가 기준이 되는 메트릭을 컴포넌트의 특성을 부여하여 정의한다. 즉, 비즈니스 컴포넌트 식별을 위하여 컴포넌트 내의 응집도는 높고 컴포넌트 간의 결합도는 낮아야 하는 컴포넌트 특성을 적용한 응집척도와 결합척도를 제안한다. 또한 컴포넌트의 응집도와 결함도의 비율에 의하여 비즈니스 컴포넌트의 독립의 정도를 평가할 수 있는 독립척도를 제안한다. 본 논문에서 제안한 응집척도, 결합척도 그리고 독립척도를 사례에 적용하여 그 효율성을 평가한다.

When a building suffers damages under moderate to severe loading condition, its physical properties such as damping and stiffness parameters will change. There are different practical methods besides various numerical procedures that have successfully detected a range of these changes. Almost all the previous proposed methods used to work with translational components of mode shapes, probably because extracting these components is more common in vibrational tests. This study set out to investigate the influence of using both rotational and translational components of mode shapes, in detecting damages in 3-D steel structures elements. Three different sets of measured components of mode shapes are examined: translational, rotational, and also rotational/translational components in all joints. In order to validate our assumptions two different steel frames with three damage scenarios are considered. An iterative model updating program is developed in the MATLAB software that uses the OpenSees as its finite element analysis engine. Extensive analysis shows that employing rotational components results in more precise prediction of damage location and its intensity. Since measuring rotational components of mode shapes still is not very convenient, modal dynamic expansion technique is applied to generate rotational components from measured translational ones. The findings indicated that the developed model updating program is really efficient in damage detection even with generated data and considering noise effects. Moreover, methods which use rotational components of mode shapes can predict damage's location and its intensity more precisely than the ones which only work with translational data.

Anchorage devices play an important role in post-tensioned bridge structures since they must sustain heavy loads in order to permit the transfer of the prestressing force to the structure. In external prestressing, the situation is even more critical since the anchorage mechanisms, with the deviators, are the only links between the structure and the tendons throughout the service life of the structure. The behaviour of anchorage devise may be studied by using the finite element method. To do so, each component of the anchorage must be adequately represented in order to approximate the anchor mechanism as accurately as possible. In particular, the modelling of the jaw/tendon device may be carried out using the real geometry of these two components with an appropriate constitutive contact law or by replacing these components by a single equivalent. This paper presents the numerical study of a mono-strand anchorage device. The results of a comparison between two different representations of the jaw/tendon device, either as two distinct components or as a single equivalent, will be examined. In the double-component setup, the influence of the wedge configuration composing the jaw, and the influence of lubrication of the anchor, will be assessed.

In this study, a method that can objectively and systematically design the layout of user interface components was developed. In order to explain its application method, the method was applied to the layout design of facsimile. In particular, in order to validate the suitability of the method, comparison tests were performed for the case of facsimile. Computer simulators for layout design were made using Micromedia Flash and comparison evaluation for an existing layout and a new layout was performed in three aspects. The first comparison method was to measure and compare its movement distance when carrying out a task in two layout models. The second one was to measure and compare users' performance. The last one was to measure and compare users' subjective satisfaction after using two models. As the result, new layout design was better than the existing design in all comparison tests. The movement distance of the new layout design model was shorter than the existing model. And, its performance including task completion time and error frequency was better and users' satisfaction was higher than the existing. In conclusion, the method that was developed in this study can be very effectively used in the layout design of user interface components.
