인터넷의 등장은 세계를 초단위 정보 소통 영역으로 묶어 정보가 사회를 주도하는 형태로 발전시켰듯이, 미래 전쟁 양상도 정보가 전쟁의 승패를 결정하는 네트워크중심전(NCW)으로 발전되고 있으며, NCW의 핵심은 무기체계간 상호운용성이다. 무기체계간 상호운용성을 확보하기 위해서는 표준화된 정보를 활용해서 연동하는 중요하며, 우리 군은 무기체계간 연동을 위해 연동메시지인 KMTF를 활용하고 있다. 그러나 현 KMTF 표준은 메시지구조(message frame)만을 제시하고 세부적인 메시지는 정의하지 않아 각 체계 개발자가 나름대로 메시지를 정의함으로써 중복된 메시지를 각 체계별로 관리하고 있고, 동일한 메시지를 다른 방식으로 적용하는 부작용이 발생할 수 있으며, 체계간 연동을 위해 별도의 변환기를 개발해야 하는 문제점이 발생하고 있다. 이를 위해 본 논문에서는 첫째, 미군 메시지포맷인 USMTF를 벤치마킹하여 무기체계에 공통 적용이 가능한 공통메시지 설계방안을 제시하며, 둘째, 메시지 생명주기 관리 및 메시지 추가등록 절차 관리를 위한 KMTF 표준 관리 절차를 제시하고, 셋째, 개정된 메시지 규격에 맞는 KMTF 관리도구 개발의 방향을 제시한다.

Because XML is a W3C standard and has characteristics like platform independent, it has a critical role in electronic commerce. Many electronic commerce systems are already using XML. Business rules and procedures should be standardized for efficient B2B electronic commerce. But a lot of companies have its own XML documents instead of standard documents. In this paper an XML message processor is designed. Clients may request services in XML and server returns response in XML in this system. This XML message processor can be applied easily and used efficiently in electronic commerce systems.

The current research aims to explore which type of identity-based message can be more persuasive for Chinese consumers to form positive restaurant brand attitude based on their cultural orientation, and to examine the roles of brand objective relevance and psychological power state in the persuasive process. The study employs a 2(identity expression focus: warmth vs. competence) × 2(message description manner: identity-defining vs. identity-referencing) × 2(experienced power state: high vs. low) between-subjects design, and conducts an online survey where 240 Chinese participants in total has responded to the questionnaires. SPSS and AMOS programs have been used to examine the hypotheses. The findings suggest that, first, the warmth-focused messages (identity-defining messages) more positively affected Chinese consumers' object relevance than the competence-focused messages (identity-referencing messages); Second, high power-experienced Chinese consumers rather than low power consumers tend to perceive more object relevance at the warmth self-defining messages; Third, brand object relevance revealed a mediation effect in the process of the warmth-focused messages (identity-defining messages) affecting brand attitude. This research offers new insight into the relationships between consumers' cultural orientation, understandings of power, and identity-based consumer behavior, suggesting marketers should take those social influences and consumer diversities into account when developing the message to persuade consumers.

This study sought to identify the interactive relationship between the individual cognitive characteristics of perceived consumer effectiveness and the impact of the message framing type of a fashion brand's sustainable marketing on consumers' brand trust. As a result of the study, it was confirmed that the fashion brand's message framing type increased consumers' perceived consumer effectiveness, and that the recipient's perceived consumer effectiveness each influenced the formation of consumers' trust in the brand. It was confirmed that the fashion brand's message frame directly had a positive effect in forming consumers' brand trust.

IoT is becoming more and more popular, along with the massive availability of cheap and easy-to-use IoT devices. One protocol that is often used in IoT devices is the Message Queuing Telemetry Transport (MQTT) protocol. By default, the MQTT protocol does not activate encrypted data security features. This MQTT default feature makes the transmitted and received message data vulnerable to attacks, such as eavesdropping. Therefore, this paper will design and implement encrypted data security using the lightweight cryptography algorithm. The focus of this paper will be on securing MQTT message data at the application layer. We propose a method for encrypting specific MQTT message fields while maintaining compatibility with the protocol's functionalities. The paper then analyzes the timing performance of the MQTT-LEA implementation on the Raspberry Pi 3+. Our findings demonstrate the feasibility of using LEA at the application layer to secure MQTT message communication on resource-constrained devices.

Recently, it is reported that the Korean Unmanned Aerial Vehicle (UAV) interface protocol (K-4586) based on STANAG-4586 is being developed to secure interoperability between UAVs. The core elements of the K-4586-based Unmanned Aircraft System (UAS) are the Core UAV Control System (CUCS), Vehicle Specific Module (VSM), Data Link Interface (DLI), and C4I systems. In UAS based on K-4586, the DLI function for transmitting and receiving messages to link UAVs is included in VSM and CUCS respectively. The Generator/Analyzer (G/A) tool is an apparatus that is developed for protocol conformance verification for VSM and CUCS, and G/A tools with DLI message transmitting and receiving should be developed separately. Core applications (VSM, CUCS, DLI) and G/A tools based on K-4586 may be developed independently depending on the developers. If the DLI message modules are different for each developer, the scope and results of protocol conformance verification will be dissimilar, and some problems may happen during system integration. In this study, common DLI message module based on the API was designed to provide the DLI message transmitting and receiving function necessary to the development of core applications and the protocol conformance verification tool of based on K-4586. When applying the proposed common DLI message module, it can be expected to shorten the UAS system development period and reduce costs, and ensure conformance of protocol. In this paper, the design and implementation method for the common DLI message module based on API was proposed and the results of functional test was described.

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.

Smart home services are growing rapidly as the development of the Internet of Things (IoT) opens the era of the so-called "Connected Living." Although personal information leaks through smart home cameras are increasing, however, users-while concerned-tend to take passive measures to protect their personal information. This study theoretically explained and verified how to design effective software update notification messages for smart home cameras to ensure that users comply with the recommended security behavior (i.e., update installation). In a survey experiment participated in by 120 actual users, the effectiveness of both emotional appeals (i.e., security breach warning images for fear appeals) and rational appeals (i.e., loss-framed messages emphasizing the negative consequences of not installing the updates) were confirmed. The results of this study provide theoretical interpretations and practical guidelines on the message design features that are effective for threat appraisals (i.e., severity, vulnerability) of smart home camera users and their protection motivation.

The international standard AIS, which stands for the safety of ship navigation and vessel traffic management, provides 27 messages to exchange the navigational information of ship. Among 27 messages, message ID 6 and 8 are defined as the binary data format to exchange application specific information and are classified into IFM for international use and RFM for national or regional use. Since international standards are based on English, there have been some needs to exchange data in Hangul text for vessel traffic management to correct the static and dynamic ships' information. In this paper, I analyze international standards to provide a Hangul text messaging service based on RFM and propose a RFM message and a simple protocol to correct information of a ship.
