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.

EMI 메시지 법적 구속력을 갖는 상용 전자 문서이므로 메시지의 무결성과 거래처간의 신분 확인을 위한 서명 방법이 필요한다. 본 연구에서는 EDI 메시지의 동보 전송에 적합한 새로운 디지털 장 서명 방법을 제안하였다. 제안한 방법은 Fiat-Shamir 서명 방식에 기분을 두고 있으며, EDI 메시지에 적합한 메시지 인증을 수행할 수 있다. 침입자 및 서명자가 해쉬 함수공격으로 조사한 메시지를 검증할 수 있다. 침입자에 의한 가장 및 재전송과 같은 농동적 공격에 안전하다. 또한 Fiat-Shamir 서명 방법보다 작은 해쉬 값을 사용하여 디치탈 서명을 수행할 수 있다. EDI 메시지의 동보 전송시 지정된 수신자들은 빠르고 안전하게 디지털 서명을 수행할 수 있다.

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.

현재의 인터넷은 짧은 기간에 급속한 성장을 했으며 이를 기반으로 하는 전자상거래도 급성장했다. 이러한 인터넷 기반의 전자상거래는 사용자와 공급자간의 효과적인 상호 사용자 인증 방법으로 웹 클라이언트 메시지 기술이 활용되고 있다. 클라이언트 메시지의 사용은 사용자 인증 및 전자상거래를 비롯한 웹 서비스의 효율성을 높여줄 뿐 아니라, 다양한 목적으로 여러 가지 기능을 제공해 주기도 한다. 하지만, 클라이언트 메시지는 평문 형태로 전송되고 저장되기 때문에 네트워크 공격, 종단 시스템 공격, 쿠키 획득공격에 정보가 쉽게 노출될 수 있다. 본 논문에서는 네트워크 전송 메시지에 보안 서비스 제공을 위해 암호 알고리즘을 이용하여 클라이언트 메시지의 보안상 문제 해결을 위해 안전한 메시지와 메시지 생성과 검증에 사용되는 클라이언트 사용자 입력 정보를 안전하게 웹 서버로 전송하기 위해 네트워크 전송 메시지에 대한 보안 서비스를 설계하였다.

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.

본 논문에서는 정전기 예측 시스템과 경고 메시지 전송 시스템으로 구성된 정전기 모니터링 시스템을 개발하였다. 정전기 예측 시스템은 현재까지의 값을 기반으로 다음 단계의 정전기의 크기를 예측하고, 예측값을 블루투스 통신을 사용하여 무선으로 경고 메시지 전송 시스템으로 전송한다. 경고 메시지 전송 시스템은 정전기 예측 시스템으로부터 들어온 경고 신호를 받아들이고, 소켓 프로그램을 이용하여 상용 SMS 사이트에 접속하여 작업 담당자의 휴대폰으로 경고 메시지를 전송한다. 정전기 예측 시스템에 사용되는 동적 가변 가중치(weight factor)를 가지는 LSR(least square regression) 기반 예측 알고리즘을 개발하였고, 모의 실험에서 가중치를 실시간으로 변화시키는 방법이 표준편차가 약 64.69V로 가장 우수하게 나타났다. 그리고 경고 메시지 전송 시스템에서 보낸 경고 메시지가 약 5초 후에 원격지 작업자의 휴대폰에 표시된 것을 확인하였다.
