Variable message signs (VMS) have the different sizes and a specific type according to the city scene and it has to be displayed by different message on the display panel in real-time. And VMS manufacturers must produce the different products in order to give a customized product to each order. In addition that, they should test and check the correct operation to each VMS product using the different message frame. That is very time and workers consuming and VMS emulator with an automatic variable message generator system is necessary. Also, the automatic message generator system is needed to real-time scheduling in order to display the message on the VMS panel like real world. In this paper, we design and implement the VMS emulator embedded the automatic message frame generator system with real-time scheduling which can set several parameters easily on the windows dialog.

This study intended to empirically verify the effect of message framing, cognitive need for closure, and type of fashion products on purchasing attitude of PB fashion products in discount stores. The design consisted of three-mixed design of 2(POP(Point of Purchase)message framing: benefit message vs. loss message) ${\times}2$(cognitive need for closure: high vs. low) ${\times}2$(PB fashion product type: utilitarian vs. hedonic). Survey of this study was conducted on 330 men and women in 20~50's in Seoul and Gyeong-gi, and a total of 287 data were analyzed. Data were analyzed with SPSS 18.0 program, and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First, it was identified that the framing type of POP message of discount store, cognitive need for closure, and PB fashion product type had significant effect on preference and purchase intention. Secondly, it was identified that consumers with both high and low cognitive need for closure had high preference level and purchase intention when they encountered the benefit message framing than the loss message framing. Thirdly, the benefit message framing was more effective than the loss message framing for hedonic PB fashion products in discount stores, but utilitarian PB fashion products did not get affected by the message framing. Fourthly, it was identified that groups with both high and low cognitive need for closure preferred hedonic PB fashion products. Lastly, it was verified that benefit message framing POP advertisement on a group with high cognitive need for closure was effective for Hedonic PB fashion products in discount stores, and utilitarian PB fashion products showed no difference in purchase intention according to the POP message framing type and cognitive need for closure.

기존 모바일 메시지 서비스는 문자, 멀티미디어, 위치와 같은 컨텐츠의 실시간 전달을 제공하지만, 컨텐츠의 분석을 통한 동적인 메시지 서비스를 제공하지 못하고 있다. 본 논문에서는 "서비스로서의 메시지" 개념을 제안하고 이를 구현하기 위한 메시지 플랫폼의 설계 방안을 제시한다. 메시지는 컨텐츠를 나타내는 '데이터' 부분과 컨텐츠의 뷰와 기능 로직을 담당하는 '템플릿'으로 분리되어 전송된다. 따라서 단말기에 템플릿이 저장되어 있는 경우 데이터 부분만 전송하면 되므로 네트워크 트래픽을 줄일 수 있으며, 템플릿의 수정을 통해 동적으로 뷰와 기능 로직을 업데이트할 수 있는 장점을 가지고 있다.

In this paper, new voice message system supporting massive outbound call is proposed. Basic idea of the proposed system is to pre-process all the text-to-speech conversion process, mixing of text and attached music file and to store the results of pre-process in the cache server which is connected to the IVR. New voice message system is optimized for the voice message system supporting massive outbound call by distributing the load of the web server caused by server-side script implementation which is accessing database and generating dynamic Voice XML document over client module and server module of web server. The proposed voice message system was test-deployed in one domestic voice message application service provider and it is shown that proposed voice message system reduced the response latency problem of test-bed voice message system.

Purpose - Current study aimed at investigating the effects of the choice easiness as a thought triggered at the time of making decision and the goal achievement emotion as a prediction of how consumers feel in the state of achieving consumption goal on brand purchase intention. And It also explored moderation role of incidental pride type such as ambient hubris pride and ambient authentic pride felt before the event in the effects of message type such as self-verifying message and self-enhancing message on the choice easiness and the goal achievement emotion. Research design, data, and methodology - Message type was divided into self-verifying message and self-enhancing message. Incidental pride type was divided into hubris and authentic pride. Smart mobile phone was selected for empirical study. And the experiment was performed with 2(pride type: hubristic versus authentic) × 2(message type: self-verifying message versus self-enhancing message) between-subjects design. Questionnaires from 215 undergraduate students were used to test hypotheses by Macro process model 7. The hypotheses were tested at each of self-verifying message group and self-enhancing message group. Results - First, both choice easiness and goal achievement emotion positively influenced on the purchase intention at both self-verifying message group and self-enhancing message group. Second, at self-verifying message group, the positive effects of self verification on both choice easiness and goal achievement emotion were higher to the customers under incidental hubris pride than to those under incidental authentic pride customers. Third, at self-enhancing message group, the positive effects of self enhancement on goal achievement emotion were higher to the customers under incidental authentic pride than to those under incidental hubris pride. However, at self-enhancing message group, the positive effects of self enhancement on choice easiness (goal achievement emotion) were not higher (higher) to the customers under incidental authentic pride than to those under incidental hubris pride. Conclusions - Focusing on the results of this study, to promote their brand purchase intention, brand managers should use self-enhancing message to induce goal achievement emotion from incidental authentic pride customers. And the brand managers should develop and use self-verifying message to induce choice easiness as well as goal achievement emotion from hubris pride customers, which in turn, promote their brand purchase intention.

In industrial distributed control systems, sensors collect data from the physical environment periodically and transmit them to the actuators, which process the control operations based on the received data. For the effective operation of the control systems, the data transmitted by the sensors has to be delivered to the actuators reliably within the deadline, and if the message reception rate of the actuators becomes lower than a threshold, then the performance of the control systems drops greatly. This paper suggests a message routing protocol to transmit periodic messages reliably in a distributed control system based on wireless sensor networks. For reliable message transmission, the proposed protocol selects a routing path whose end-to-end message reception rate is the highest before transmitting data messages. The proposed protocol has the capability of maintaining a target message reception rate for each flow. To maintain the required target reception rate, each destination monitors the actual message reception rate periodically and transmits a feedback message to the source if it drops below the target reception rate. On receiving the feedback message, the source tries to find a new path which can satisfy the target rate. The performance of the proposed protocol has been evaluated using simulation and compared with other protocols in terms of the message reception rate, the message delay and delay jitter, and so on. The simulation results show that the proposed protocol has a higher message reception rate and comparable message delay and delay jitter to other protocols. The simulation results also show that the proposed protocol has an ability to adapt well to the dynamic network traffic change.

메시지전달 프로그램에서 발생하는 메시지경합은 프로그램의 비결정적 수행결과를 초래하므로 효과적인 디버깅을 위하여 탐지되어야 한다. 메시지경합을 탐지하는 기존의 도구는 임의의 메시지를 수신하는 모든 사건에서 경합이 발생한다고 보고한다. 그러나 메시지들이 전송되는 논리적인 통신채널이 서로 다르면 임의의 메시지를 수신하는 사건에서 경합이 발생하지 않을 수도 있으므로, 기존 도구의 부정확한 탐지정보는 프로그래머의 디버깅 작업을 더욱 어렵게 한다. 본 논문에서는 메시지 송수신 사건간의 병행성과 메시지들의 논리적 통신채널을 검사하여 보다 정확하게 메시지경합을 탐지하는 도구인 MPIRace-Check를 제안하다. 본 도구는 vector timestamp를 이용하여 프로그램 수행 중에 메시지를 전송하는 송수신 사건들간의 병행성을 검사하고, 메시지 부가정보를 이용하여 메시지들의 논리적인 통신채널이 동일한지를 검사하여 메시지경합을 탐지한다. 실험에서는 MPI_RTED와 벤치마크 프로그램을 이용하여 본 도구가 프로그램 수행 중에 효율적으로 모든 경합을 정확하게 탐지함을 보인다. 따라서 본 도구는 메시지경합을 정확하게 탐지하여 프로그래머의 디버깅 부담을 줄이고 신뢰성이 있는 병렬 프로그램의 개발을 가능하게 한다.
