  • A cable-stayed bridge (CSB) is one of the most complicated structures, especially when subjected to earthquakes and taking into consideration the effect of soil-structure-interaction (SSI). A CSB of a 500 m mid-span was modeled by the SAP2000 software and was subjected to four different earthquakes. To mitigate the harmful effect of the vibration generated from each earthquake, four mitigation schemes were used and compared with the non-mitigation model to determine the effectiveness of each scheme, when applying on the SSI or fixed CSB models. For earthquake mitigation, tuned mass damper (TMD) systems and spring dampers with different placements were used to help reduce the seismic response of the CBS model. The pylons, the mid-span of the deck and the pylon-deck connections are the best TMDs and spring dampers placements to achieve an effective reduction of the earthquake response on such bridges.

  • In this paper, we design the robust H$_{\infty}$ controller for congestion control in ATM (asynchronous transfer mode) networks with the variation of other higher priority sources(e.g., constant bit rate, variable bit rate). Since ABR (available bit rate) sources share the bottleneck node with other higher priority sources, we design the controller which guarantees robustness against time delay and disturbance. The proposed robust H$_{\infty}$ controller with regional pole placements can minimize the variation of the queue size at the predefined desired level. And we also show its robustness through simulation for the ATM networks with time delay and disturbance.

  • Research on purchase intention had showed remarkable progress in contributing to the theory of consumer behavior. Despite the popularity of academic discussions on various issues influencing purchase intention, the mediating role of brand recall and brand attitude on purchase intention, in particular advergames, has not yet been well explored, especially in developing economies such as Malaysia. Furthermore, the influence of self-brand congruity, entertainment and brand placement acceptance as antecedents to brand recall and brand attitude are expected to add value to the brand recall, brand attitude and purchase intention relationships. This paper aims to investigate the impact of the mediating role of brand recall and brand attitude on purchase intention in advergames among Malaysian gamers. The antecedents towards brand recall and brand attitude are also examined to measure their influence on purchase intention. A total of 350 Malaysian gamers were interviewed through online survey in this study. The results showed that brand recall and brand attitude mediate the relationship between self-brand congruity, entertainment and brand placement acceptance with purchase intention. Also, entertainment and brand placement acceptance were found to have a significant relationship with brand recall. As expected, brand recall and brand attitude showed a positive relationship with consumer purchase intention in advergames. It was found that self-brand congruity has a significant influence on brand attitude and purchase intention. When users see the brand which matches with them, they tend to act positively toward the brand exposed in the game. This is consistent with Escalas and Bettman (2005) who suggested that the greater the congruity, the more positive the consumer's attitude toward the brand in question. This leads to game usage and purchase (Davis and Lang, 2013). In the advergaming context, the entertainment value in advergames is very important to determine the level of enjoyment and pleasure experienced by gamers during game-playing. Therefore, the more entertaining the ads, the more it will be remembered and the greater the positive behavior of the consumer towards the advergames - this ultimately stimulates their intention to purchase the brand. This study shows the effect of brand placement on brand recall and brand attitude and also purchase intention. Brand placements might not work in games due to the interactivity involved in game-playing as people could be distracted from noticing the brand placements (Yang et al., 2006). However, the significant influence of brand placements found in this study may provide major promise for advertisers. Game players may or may not explicitly remember the brands they see in the games, but these placements may influence their brand recall and brand attitude and could therefore influence later decisions (Yang et al., 2006). In this study, it was found that self-brand congruity was not significantly related with brand recall. The reason for this could be attributed to the fact that this study examined gamers who are highly involved in the interactive medium of games which force them to focus on game play rather than advertisements; the level of recognition to remember the brand exposed in the game is low and contributes to the "mismatch" between the gamers and the said brand. The present study contributes to the existing literature of the antecedents of brand recall and brand attitude in advergames. This study contributes to the role of brand recall and brand attitude as mediators in purchase behavior theory. Academically, the relationship between brand recall and brand attitude is well known in advergaming research, but their impact as important mediators on purchase intention add new understanding in the interactive communication literature. Their mediating role may provide new insights on how they facilitate the effects of self-brand congruity, entertainment and brand placement on purchase intention. Besides that, the studies on the influence of self-brand congruity on brand recall and brand attitude and also consumer intention to purchase had not well-investigated in advergames. This study contributes to fill those gaps in advergames literature. For practitioners, this study could suggest the use of illustrative or demonstrative placements of new products to help customers remember new brands, and the use of associative placements for existing products to increase consumers' purchase intention (Ho et al., 2011). To advertisers, this study may provide useful information to improve their current advertising strategies in games, for instance, by considering game players' congruity, entertainment value and brand placement factors.

  • In this study, a novel and flexible recommender system was developed, based on product taxonomy and usage patterns of users. The proposed system consists of the following four steps : (i) estimation of the product-preference matrix, (ii) construction of the product-preference matrix, (iii) estimation of the popularity and similarity levels for sought-after products, and (iv) recommendation of a products for the user. The product-preference matrix for each user is estimated through a linear combination of clicks, basket placements, and purchase statuses. Then the preference matrix of a particular genre is constructed by computing the ratios of the number of clicks, basket placements, and purchases of a product with respect to the total. The popularity and similarity levels of a user's clicked product are estimated with an entropy index. Based on this information, collaborative and content-based filtering is used to recommend a product to the user. To assess the effectiveness of the proposed approach, an empirical study was conducted by constructing an experimental e-commerce site. Our results clearly showed that the proposed hybrid method is superior to conventional methods.

  • As more consumers avoid ads aided by advanced technologies that conveniently block ads, traditional advertising is becoming less effective than ever before. Product placements are increasingly executed to unobtrusively expose products and brands to consumers while they watch media programs. The current study attempts to enhance our understanding of the factors that affect consumer attitude towards the brands placed in TV dramas. In particular, this study examines whether the attractiveness of actors and the congruency between the products placed and the story of the TV drama influence consumer attitudes towards the TV drama and the brand. A total of 211 male consumers in their 20s and 30s were used for data analyses. Structural equation modelling revealed that the product-story congruence had a positive impact on consumer attitude towards the TV drama as well as their attitude towards the brand. Actor attractiveness (in terms of similarity and likability) positively influenced consumer attitude towards the brand. Only the perceived likability dimension of actor attractiveness was found to affect consumer attitude towards the TV drama.

  • 보조정보 생성기법은 분산 비디오 부호화 기법(DVC: Distributed Video Coding)에서 핵심적인 역할을 수행한다. 대부분의 기존 보조정보 생성 기법은 복원된 키 프레임을 참조영상으로 블록중심으로 대칭형 움직임 탐색 기법을 주로 사용하고 있다. 그러나 이와 같은 방식은 움직임 탐색에 얻어지는 움직임 벡터가 복원하고자 하는 블록의 위치와 일치하지 않는 경향이 있으며 보조정보의 성능을 개선하는데 제한적이다. 이와 같은 문제점을 극복하기 위해, 본 논문에서는 움직임 벡터가 복원하고자 하는 블록의 중심 위치에서 대칭이도록 하는 블록중심 대칭형의 움직임 탐색 기법을 제안하고, 이와 같은 움직임 탐색법에 기초한 보조정보 생성 기법을 제안한다. 제안한 방식은 기존의 단순 대칭형 움직임 탐색방식에 비해 우수한 객관적 화질을 얻을 수 있음을 모의실험을 통해 보인다.

  • This paper presents the linear model of the measurement system with Phasor Measurement Units (PMU's) and the parallel processing technique to determinate state vectors of a power system. The conventional model of the PMU measurement system is in a dilemma that it is not applicable to optimal PMU placements and it needs more PMU to apply this model. In order to improve this defect, in this paper, the extended linear model which adaptable to optimal PMU placements considering the feature of zero injection bus is proposed. Because the proposed model is expressed as over-determined measurement equation, the efficient algorithm is needed. This paper proposed the partitioning scheme and the process algorithm for parallel determinating state vectors of a power system efficiently. The performance of the proposed linear model and the parallel processing algorithm is evaluated with IEEE sample systems.

  • Custom VLSI 칩의 설계에 있어서 임의의 폭과 높이를 갖는 직사각형 마크로 블럭을 효과적으로 배치하는 것은 칩의 면적과 신호 지연시간을 줄이기 위하여 매우 중요하다. 이 논문에서는 시뮬레이티드 어닐링을 사용하여 마크로 블럭을 전체적으로 최적 배치하기 위한 방법과, 시뮬레이티드 어닐링 과정이 끝난 후에 남아있는 직사각형 블럭들 사이의 중첩을 제거하는 효율적인 알고리듬을 제안하였다. 최소한의 배선영역을 확보하기 위해 각 블럭을 4방향으로 확장한 후에, 확장된 블럭들을 최대한 밀집되도록 배치하였다. 이 방법을 MV10000/UNIX 컴퓨터에서 C언어로 프로그램 하였으며 50개와 160개의 블럭으로 구성된 회로에 적용한 결과 좋은 배치를 얻을 수 있었다. 또한 최종 배치에 큰영향을 주는 파라미터에 대한 조사를 하였다.
