Purpose - In recent years, many companies include franchises have acquire customers by making an online stores and they are carrying out permission marketing activities with e-mail and SMS. Permission marketing requires voluntary customer approval for receiving commercial messages such as cross-selling and upselling. Therefore, it is necessary for the business to induce the customer's acceptance. The purpose of this study is to examine which type of different messages can affect higher in consumer persuasion. Thus, we investigated the impact of descriptive norm message on intention of reception in an online store context, and its interaction with chronic regulatory focus. Research design, data, and methodology - This study hypothesized that the descriptive norm message would affect positive influences to consumers' intension of reception. Specially, this study inquired into whether the interaction effect between descriptive norm and regulatory focus. To verify the hypothesis, we conducted 2 × 2 between-subject factorial design with message type (general message and descriptive norm message) and regulatory focus(promotion focus and prevention focus) as independent variables. Participants of the experiment were assigned to one of 2 kind experimental situations randomly according to characteristics of message type. A total of 131 participants (descriptive norm message: 65, general message: 66) responded for this study. The data were analyzed using frequency analysis, exploratory factor analysis, and two-way ANOVA. Result - The results of the study are as follows. First, we found main effects of the descriptive norm message. The intention of reception were significantly higher in the descriptive norm message rather than general message as in previous researches. Second, interaction effect between the descriptive norm message and regulatory focus was significant. The prevention focus (vs. promotion focus) were hight in a positive behavior intention when the descriptive norm message was given. Conclusions - This study verifies the main effect and interaction effect of descriptive norm message and regulatory focus on the consumers' intention of reception in permission marketing, and persuasive message in the online store context. The results of this study will provide various advantages to companies that want to establish long lasting relationship with customers by carrying out permission marketing in the future.

As the EDI message is the commercial electronic document having legal binding forces, it is necessary to use the method of digital signature for the message integrity and identification between trading partners. This research proposes a new digital multisignature scheme suitable for transmission to multi-destination of the EDI message. The proposed scheme is based on Fiat-Shamir signature scheme and can perform the message authentication suitable for the EDI message. It can verify the message forged by a hash function attack from intruder or intruder. It also can perform the digital signature using smaller hash value than that of Fiat-Shamir signature scheme. When the EDI message is transmitted to multi-destination, all designated receivers can perform the digital signature faster and safer.

This paper presents an implementation method of Profibus interface software using FMS(Fieldbus Message Specification). The Profibus interface software is implemented on PC which is widely used as an industrial computer as well as a commercial embedded controller called IUC(Intelligent Universal Controller). In order to enable the Profibus interface software to handle many application tasks and communication services, two kinds of real-time/multi-tasking operating system, OS-9 and CTask, are utilized. We also develop an experimental model of Profibus-based automation system, and evaluate the performance of the Profibus network. Through experiments, the user layer level message latency is measured with respect to the change of message length, message generation interval and TRT(Target Rotation Time). The results of experiment are compared with those of a simulation model which comprises only the physical and data link layers of Profibus. The results of this study shows that the message latency in the user layer level occupies fairly a large part of the total message latency.

As th Internet grew rapidly, the Electronic Commerce that is based on Internet increased. The Electronic Commerce is unsubstantial in the mutual authentication between the parties and a commerce As a solution to this issue, a Web server uses a Client Message technology. The purpose of Client Message is to validate the user and the electronic commercial transaction. Further, it increases efficiency and offers several ability at various purposes. However, the Client Message is transferred and stored as an unencrypted text file, the information can be exposed easily to the network threats, end system threats, and Client Message harvesting threats. In this paper designed by used crypto algorithm a Secure Message as a solution to the issue have proposed above. Further, designed a security service per Network transmitting message to transfer client's user input information to a Web server safety.

Where a paper document, a manual signature, or negotiability is required in statute, then solutions must be found through a change in the law. However, where the problem originates in commercial usage, then the solution can be easier, and speedy. Certainly, nearly all of the functions that paper document provides can be equally, or better, satisfied by electronic means. That is, Electronic Commerce(EC), which has been increasing rapidly and is a new type of transaction, may be hindered by legal obstacles to use of Electronic Message, or by uncertainty to its legal effect and validity. Therefore, it is important to sustain legal effect to Electronic Message for the prosperity of EC The one of solutions is to use reliable Electronic signature system by Certification Authority to verify the authenticity of Electronic Message.

We often feel the necessity to communicate with members involved in a project to remote discuss business activities, needs for the fast file transfer, and check the existence of members to talk with. There are some commercial applications in these problems. However, in addition to those existing functions, this study focuses especially on adding couple of functions such as automatic responding function, in which a sender of a message automatically knows if a receiver checks the message. Its application is that a project leader sends an important message and later on can check at his desk the fact that who have checked their messages. The prototype application, build in this study, will check the correctness of every sub-function, and then the interface of inter-sub-functions, finally the integrity of the entire system, so that important information will not be lost among members of a project in the real world situation.

When a receiver of ciphertext message can not decrypt a message because he has lost his private-key, the private-key of receiver and session-key of the message should be recovered. In this paper, we developed an Encapsulation based Key Recovery System (EKRS). EKRS is a new key encapsulation based key recovery system which is characterized by secretly choice of KRA, randomized target keys. n-way recovery type, and useful for commercial key recovery. EKRS is formally specified by a pictorial model, an Extended Cryptographic Timed Petri Net (ECTPN). Secure information flow and reachability of a session-key are verified by using reachability graph of ECTPN. EKRS, executing over a Public Key Infrastructure, can be used as a security solution in Web based applications such as CALS, EC an EDI.

Video games are an alternative channel for public health authorities constantly striving to reach target audiences and make positive changes. The objective of this research is to address effectiveness of health games as a health promotion technology for anti-smoking communication. This study tested the impact of advertising message types and voice-over relative to anti-smoking persuasion. By using commercial-level custom-made first person shooter (FPS) games, two experimental studies demonstrated usefulness of applying health games to change a player's attitude towards smoking. In particular, an interactive in-game message with a persuasive voice over was the most effective method to change targets' attitude towards smoking. Findings of our research offer meaningful insight on health promotion research and provide possible directions for future anti-smoking communication using health games.

In this paper, we develop an electrostatic monitoring system which is composed of an electrostatic prediction system and a warning message transmission system. The electrostatic prediction system in a factory receives the value of electrostatic charge from the electrostatic sensor and predicts the next value by using past data and sends the value to the warning message transmission system through the bluetooth communication. The warning message transmission system gets a warning signal and transmits the warning message to the worker's cellphone through a commercial SMS web by a socket program running on Windows PC in a control room. We propose electrostatic forecasting algorithms based on LSR(least square regression) using weight factors in an electrostatic prediction system. Simulation results show that the algorithm with dynamically variable weight factors is best with 64.69V standard deviation and a warning message transmitted by the warning message transmission system is displayed on cellphone after about 5 seconds.
