에이전트간의 통신 방법에는 에이전트간 직접 통신을 하는 직접 통신 방법과 다른 매개체를 이용하여 통신하는 간접 통신 방법이 있다. 기존 연구에서의 직접 통신 방식은 에이전트의 위치를 계속하여 추적하고 관리하는 방식으로 동기 통신을 지원하고, 간접 통신 방법은 매개체를 두어서 그를 통한 비동기 통신방법을 지원한다. 하지만, 직접 통신의 경우, 에이전트의 추적과 관리에 따라 오버헤드와 공동 작업에 필요한 멀티캐스팅을 지원하기 어려운 문제점이 있어 이동 에이전트에는 부적합한 통신방법이고, 간접통신의 경우 동기적 상호작용을 지원하기 어렵다. 따라서 본 논문에서는 기존의 간접 통신방법을 확장하여, 멀티캐스팅 기능과 동기 통신 방식을 지원하는 에이전트간의 통신 관리자를 설계한다. 이를 위해서 에이전트의 이벤트 리스너를 통신관리자에 등록을 시켜서 이벤트가 발생할 때마다 해당되는 에이전트에게 전달되도록 하였다. 또한 통신 관리자가 멀티캐스팅 기능을 지원하도록 하였다. 이렇게 함으로써, 공동 작업에서 필요한 신뢰성 있는 동기 통신 방식과 멀티캐스팅 기능을 지원함으로써 이동 에이전트 기반 CSCW 응용개발에 사용할 수 있다.

This study is a cross cultural examination of interactivity, comparative advertising, and technology use in Korean and U.S. corporate websites. Utilizing cultural analysis criteria of high vs. low context, power distance and individualism-collectivism, we compared interactivity in U.S. and Korean websites. Our findings indicate that U.S. corporate websites tend to emphasize customer-message and customer-advertiser interactivity, while Korean websites highlight customer-customer interactivity. Findings on comparative advertising strategy indicate that cultural bias represented in U.S. individualism and Korean collectivism leads U.S. web advertisers to utilize direct and indirect comparative advertising more frequently than their Korean counterparts. The results of our technology analysis unexpectedly show that there is no significant difference between the two countries.

Strichartz and Richie have suggested that the mechanism of sodium donductance block of local anesthetics involves their interaction with a specific binding site within the sodium channel. However, there is evidence that local anesthetics can interact electrostatically with membrane proteins as well as membrane lipids. Whether or not all actions of local anesthetics are mediated by common site remains unclear. Thus, it can not be ruled out that local anesthetics concurrently interact with neuronal membrane lipids since sodium channels were found to be tightly associated with membrane lipids through covalent or noncovalent bonds. In summary, it is strongly postulated that local anesthetics, in addition to their direct interaction with sodium channels, concurrently interact with membrane lipids, fluidize the membrane, and thus induce conformational changes of sodium channels, which are known to be tightly associated with membrane lipids.

Several researches in 3D interaction have identified and extensively studied the four basic interaction tasks for 3D/VE applications, namely, navigation, selection, manipulation and system control. These interaction schemes in the real world or VE are generally suitable for interacting with small graspable objects. In some applications, it is important to duplicate real world behavior. For example, a training system for a manual assembly task and usability verification system benefits from a realistic system for object grasping and manipulation. However, it is not appropriate to instantly apply these interaction technologies to such applications, because the quality of simulated grasping and manipulation has been limited. Therefore, we introduce the intuitive and natural 3D interaction haptic interface supporting high-precision hand operations and realistic haptic feedback.

The interactions of natural atmospheric electricity with aircraft reveals many flight safety problems. It is estimated that on average, each commercial airplane is struck by lightning more than once each year. Thus the lightning strike to aircarft poses an appreciable threat to flight safety. Upset or damage of electrical and electronics equipment by the induced voltages is defined as indirect effect. The protection of aircraft electronics from the indirect effects of lightning can be accomplished first by determining the specific threats to the aircraft and systems contained within, and second, by designing protection methods to the aircraft components.

In this study, to analyze the relationship between exercise satisfaction and exercise continuity that occurs in the interaction between leaders and participants, non-probability sampling was performed on 232 individuals from January 17 to March 9, 2022, and a structural model of 187 effective samples was used. applied and analyzed. First, the reliability and intimacy of Pilates leader-participants were found to have a significant effect on exercise satisfaction. Second, significant results were derived between Pilates exercise satisfaction and exercise continuity. Third, Pilates reliability was found to have a significant effect on exercise continuity, but intimacy was partially adopted as not having a significant effect on exercise continuity. However, the indirect effect between the mediating effects of exercise satisfaction can be seen to be statistically significant, and it can be predicted that Pilates causes positive behavior in exercise satisfaction and further reduces avoidance or indirectly affects other exercises. In addition, these performances are considered to have an impact on business performance as well as mutual relationships.

Recently, various interactions have been actively conducted through sharing and expressing opinions among users in social networks. In this process, since malicious users and fault information spread misinformation, trust is reduced irrespective of their will. To solve this problem, studies have been conducted to determine the trust of a user through direct-connected users. In this paper, we propose a enhanced user indirect trust discrimination scheme considering the connection relation and influence of users. The proposed indirect trust computation scheme derives the user's area of interest through user interaction and reconstructs the existing network considering the user connection relationship. The final indirect trust is also detected by determining whether the user is a malicious user through the influence of the user. Through various performance evaluations, we show that the proposed scheme achieves better performance than the existing method.
