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.

Previous research on negative contents of verbal message being more influential has a two broad streams as impression formation theory and negative information having an more diagnostic informational value. Therefore, this research was intended to obtain consistent results from researches by message frame segmentation of verbal message and to determine the medium of verbal message. It was proven from the research that objects influencing verbal message are being effected by the participation ratio of products and the positive indication is having more meaningful difference than the negative indication statistically unlike to the results of previous researches. Unlike just a biased positive message or negative message as the result of previous research, it was proven that the positive indication is influential regardless of sequences according to participation ratio and site participation in case of positive and negative being existing together.

In this paper, we present a message transfer scheme for efficient message passing in the hierarchically structured multiprocessor computer SPAX(Scalable Parallel Architecture computer based on X-bar network). The message transfer scheme provides interface not only with operating system but also with end users. In order to transfer two types of control message and data message efficiently, it supports both of memory-mapped transfer and DMA-based transfer. Dual-port RAMs are used as message buffers, and control and status registers provide efficient programming interface. Interlaced parity scheme is adopted for error control. If any error is detected at receiving node, errored packet is resent by sender according to retry mechanism. In conjunction with retry mechanism, watchdog timers are used to protect infinite waiting and repeated retry. The proposed message transfer scheme can be applied to input/output nodes and communication connection nodes as well as processing nodes in the SPAX.

The goal of this study is to identify how different types of messages can contribute to the effectiveness of social media in healthier dietary behavior. The sample consisted of 160 participants who use social media and participants were randomly assigned to one of the four experimental conditions. The study shows that a positively framed message paired with a health focused message and a negatively framed message paired with a body image focused message exhibit a positive eWOM and message perception. This research offers direction for development of appropriate message types to improve social media effectiveness. Social media marketers and advertisers can develop social media content on healthier dietary behavior.

Although message services in mobile environments provide real-time transfer of various contents such as text, multimedia and location, they can't provide dynamic message services based on analysis of message contents. This paper proposes "message as a service" concept and presents the design methodology for a message platform. The message in this paper is composed of the data part and template part which is in charge of view and functional logic of contents. In addition, two parts of a message are transferred separately. If a terminal device stores message templates, message platform can transfer data part only and thus network traffic can be reduced. Besides an efficient network utilization, we can dynamically update message view and its functional logic by modifying templates.

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.

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.

Message races should be detected for debugging effectively message-passing programs because they can cause non-deterministic executions of a program. Previous tools for detecting message races report that message races occur in every receive operation which is expected to receive any messages. However message races might not occur in the receive operation if each of messages is transmitted through a different logical communication channel so that their incorrect detection makes it a difficult task for programmers to debug programs. In this paper we suggest a tool, MPIRace-Check, which can exactly detect message races by checking the concurrency between send/receive operations, and by inspecting the logical communication channels of the messages. To detect message races, this tool uses the vector timestamp to check if send and receive operations are concurrent during an execution of a program and it also uses the message envelop to inspect if the logical communication channels of transmitted messages are the same. In our experiment, we show that our tool can exactly detect message races with efficiency using MPI_RTED and a benchmark program. By detecting message races exactly, therefore, our tool enables programmers to develop reliable parallel programs reducing the burden of debugging.
