This research was to investigate the role of message regulatory focus on the advertising effect of multiple models. The multiple models are limited to two models in one advertisement in this research. This research investigated the hypothesis that multiple models, in terms of multiple source effect and social consensus, appears specifically to enhance the relationship of consumer and commercial models on the conditions of promotion-focused message which leads to the information processing of relational elaboration. This research applied a between-subjects factorial design targeting 2(the number of model: single model vs. multiple models) by 2(message regulatory focus: promotion-focused message vs. prevention-focused message). As a result, multiple models showed more positive ad attitude, brand attitude, and purchase intention than did single model. And promotion-focused message with multiple models showed more positive ad attitude, brand attitude, and purchase intention than did prevention-focused message with multiple models. Also there was an interaction effect between the number of model and the type of message regulatory focus. It wasn't fully supported that there is no difference of advertising effect between promotion-focused message and prevention-focused message on the condition of single model.

This paper analyses the message complexity of TDMA ad hoc MAC protocols. Since the network resource of ad hoc networks is limited due to the multiple interferences and the contention-based wireless channel, the scalability issue is one of the main research topics in developing ad hoc algorithms. Simulation demonstrates that SMACS protocol has the lowest message complexity, whereas TMMAC has the highest. In addition, it is found that since the effect of unicast dominates in the message complexity compared to other factors with an increasing number of nodes, Z-MAC tends to have the property of linearity, whereas BMA and TMMAC show exponential increases in their complexities.

MiTS communication is a protocol for the exchange of various information among shipboard systems. It also specifies more than 30 specialized message formats for the information exchange. To build MiTS systems, therefore, the messages should be processed consistently. This paper proposes the design and implementation of such message processing modules. It also describes the test results of the implemented modules.

EJB (Enterprise Java Beans)는 웹 응용 서버 스펙인 J2EE(Java2 Enterprise Edition)의 핵심으로서, 비즈니스 업무를 웹 환경에서 컴포넌트 형태로 작성하여 재 사용성을 높이기 위한 서버 측 컴포넌트 프로그래밍 모델이다. EJB는 컴포넌트를 특성에 따라, 일반적인 비즈니스 로직을 나타내는 세션 빈(Session Bean), 데이터베이스에 저장된 정보와 같은 여러 클라이언트에 의해 공유되며 영속 장치에 저장되는 엔터티 빈(Entity Bean) 그리고 JMS메시지를 처리하는 메시지 드리븐 빈(Message-driven Bean)으로 구분한다. 본 논문에서는 ETRI에서 개발한 E504 EJB 서버에서 여러 클라이언트가 하나의 엔터티 빈에 동시에 접근할 경우 데이터 일관성 유지를 위한 동시성 제어 방법에 대해 논의한다.

As the types of actions and the magnitude of the required actions for environmental improvement get diversified, the necessity to develop effective messages is increasing. This research tries to develop proper messages with message characteristics of message framing and value orientation per different types of behaviors using a 2(message framing: gain/loss) × 2(value orientation: individual/social) × 2(magnitude of the requested behaviors: high/low). The results showed that framing and the magnitude of the requested behaviors had main effects on message attitudes and behavioral intentions. The gain framing showed more favorable effects than the loss framing, and the low magnitude of the requested behaviors showed better persuasive effects. According to the results of interaction effects, the gain framing showed higher behavioral intentions than the loss framing in the individual-oriented message, and there were no differences between the frames in the social-oriented message. When the magnitude of the requested behavior was high, the gain framing in the individual-oriented message was more favorable than the loss framing. On the other hand, when the magnitude of the requested behavior was low, the gain framing in the social-oriented message was more favorable. Although there were differences in the form of interactions by the magnitude of the requested behaviors, the individual-oriented gain framing message was found to be the most effective.

This study investigate the interaction effects of bundle price discount framing and message framing on consumer's attitude of bundle component. Although each effect of bundle price discount framing and message framing has been explored individually, few attempts have been made to invest them jointly. This study tests the interaction effects of bundle price discount framing and message framing on consumer's evaluation of bundle component. Moreover, this research focuses on consumer's evaluation of individual bundle component while the existing research on bundling primarily focused on consumer's evaluation of the bundle. Prior research suggests that consumers are sensitive to the framing of prices and discounts in the presentation of the bundle offer. For example, there is considerable evidence that partitioning or consolidating the prices of a bundle can influence the attractiveness of the bundle offer. Similarly, there is evidence that an equivalent price reduction to the overall bundle, one of the individual products in the bundle, or distributed among the individual products in the bundle can alter the perceived attractiveness of the offer (e.g. Chakravarti, Krish, Paul, and Srivastava 2002; Hamilton and Srivastava 2008; Janiszewski and Cunha 2004; Johnson, Herrmann and Bauer 1999; ; Morwitz, Greenleaf, and Johnson 1998; Yadav 1994; 1995). In line with these earlier research, this research suggests that the bundle type can influence the consumer's evaluation of bundle component. There are two types of bundle - mixed-leader bundle and mixed-joint bundle. In mixed-leader bundling, the price of one of the two products is discounted when the other product is purchased at the regular price. In mixed-joint bundling, a single price is set when the two product are purchased jointly. This study supposes that the teeth whitening product is the leader product in a mixed-leader bundle. So bundle price discount framing is manipulated such as "Buy the teeth whitening product (regular price \80,000) and get 50% discount on the functional toothpaste(regular price \40,000), special set price \100,000" or "Buy the functional toothpaste and the teeth whitening product as a set and get discount for the set, special set price \60,000". Message framing is manipulated through the product claims described in an advertising bill. The positive framing presents that "Over 95% of users achieved the expected 2-3 shades of improvement in two weeks" where as the negative framing presents "less than 5% of users did not achieve the expected 2-3 shades of improvement in two weeks". This study uses hypothetical brand name of the teeth whitening product and the functional toothpaste This study is based on a 2x2 factorial design with bundle discount framing (mixed-leader bundle vs. mixed-joint bundle) and massage framing (positive vs. negative). The dependant variables are consumer's perceived quality and attitude of the teeth whitening product The data reveals that two dependant variables are correlated, so the data is analyzed with two-way MANOVA. This research explores the significant interaction effect of bundle discount framing and message framing on consumer's perceived quality and attitude of the teeth whitening product. When the message framing is positive, consumer's perceived quality and attitude of the teeth whitening product is higher in mixed-leader bundle than mixed-joint bundle condition. However, when the message framing is negative, consumer's evaluation is higher in mixed-joint bundle than mixed-leader bundle. The author explains this result by stating that consumers are less likely to use heuristics such as price-quality association and value discounting hypothesis(Raghubir 2004) in the negative message framing condition. Additionally, consumer's perceived risk of the teeth whitening product in the negative message framing condition can be more reduced by the bundle partner(e.g. the toothpaste) in mixed-joint bundle than mixed-leader bundle. Based on the results, marketing managers are advised to use different bundle type based on message framing of their product.

링 형태로 구성된 하나의 네트워크에서 선로의 단절 등 이상이 발생하면 네트워크상 모든 노드들의 네트워크 계층간 라우팅 정보가 변경되는 경로 재 설정 시간동안 이상이 발생한 선로를 경유하는 패킷들은 전송에 실패하게 된다. 특히, 전송시스템으로 구성된 네트워크에서는 서로의 이상 발샐 후 이를 감지한 전송시스템은 관리자에게 알리기 위한 해당 경보 메시지를 생성하여 전송하게 되나 네트워크 계층의 경로 재 설정 시간으로 인하여 이 긴급하고 중요한 메시지에 대한 전송을 보장하지 못한다. 이는 관리자가 선로 이상에 대한 적절한 조치를 즉각적으로 취하지 못하는 심각한 문제를 발생시킨다. 본 논문에서는 이러한 문제 해결을 위하여 네트워크 계층의 경로 재 설정 과정이 이루어지는 일정 시간동안 데이터 링크 계층에서 빠른 경로 재 설정 기능을 수행하는 전송시스템을 제안한다
