Rendezvous is a process of two or more cognitive radio nodes gathering on the same channel at the same time for a negotiation to establish data communications. This paper discusses rendezvous issues in cognitive radio networks. It details why rendezvous is an issue in cognitive radio networks and how rendezvous works. It classifies channel access methods, and details sequence-based channel-hopping methods. It surveys existing works on blind rendezvous and compares the proposed algorithms in terms of the maximum time to rendezvous. This paper discusses the properties that an efficient channel-hopping rendezvous algorithm should have and illustrates common issues in the existing rendezvous methods. It also explains open research issues in the rendezvous area.

The aim of this study is to examine opinions discussed on the structure of the PA between MOMAF, Pusan city and Inchon city by analysing and reviewing the reports and debates with the Promotion Committee. In addition, this paper is to find out the reasons why they have different views and opinions over the establishment of PA and to analyze how such conflicting opinions will influence on future operation in the PA. On the bases of the above research, this study suggests a more rational proposal to establish the PA not from the result of the negotiation between the interested parties, which have involved in the process of establishment of the PA, but from the viewpoint of principles.

Agent-based modeling (ABM), as a relatively new simulation technique, has recently gained in popularity in the civil engineering domain due to its uniquely advantageous features. Among many civil engineering applications, ABM has been applied to facility operation and management, such as energy consumption management, as well as the enhancement of maintenance and repair processes. The former studies used ABM to manage energy consumption through simulating human energy-related behaviors and their interactions with facilities, as well as electrical, heating, and cooling systems and appliances, while the latter used ABM to enhance maintenance process through facilitating coordination, negotiation, and decision making between facility managers, service providers, and repair workers. The present study aims to provide a short qualitative review on the most recent applications of ABM in the above-mentioned areas. Based on the review and follow-up analysis, the study identifies the advantages, disadvantages, and limitations of ABM applications to facility operation and management, and offers several potential future research topics in the hope of filling the existing literature gaps.

The Internet Key Exchange (IKE) protocol is most widely used as a security key exchange protocol on the Internet. Security policies used by the IKE protocol must be configured in advance, however the complex options and manual settings cause inconvenience. This paper proposes an automatic configuration method for the IKE protocol based on X.509 certificate. Security policies are embedded in the certificate, read, and added into the IKE configuration file by a negotiation assistant module in order to achieve automatic IKE configuration. Our proposed method reduces the complexity of configuration process and improves the adaptability of the IKE protocol.

Mediation is defined most simply as facilitated negotiation. An impartial third party(the mediator) facilitates negotiations between disputants or the disputants' representatives in their search for a resolution of their dispute. The disputants remain responsible for negotiating a settlement; the mediator's role is to assist the process in ways acceptable to the disputants. Sometimes this means merely providing a forum for negotiations or convening the negotiations. More often it menas helping the disputants find areas of common ground for resolution, offering alternatives, supervising the bargaining, then drafting the final settlement. mediation can occur between two disputants seeking to resolve one issue, or among many disputants seeking to resolve several issues. The disputants can participate in mediation themselves or they can have representatives negotiate for them. Mediation most often is a voluntary process. In Korea, as mediation could not have developed for lack of people's correct understanding on it, there must be enlightenment against the people, and it needs subsidiary from government and support from lawers. In order for the lawers to accomplish their role in progressing mediation procedure favorably, they should study and develope on the skill on mediate the case. Furthermore through the good mediation system, it also needs to induce the parties to participate in mediation procedure voluntarily. On the other hand, It also needs to bring up and develope the ADR institution to proceed the mediation impartially and effectively, and let them improve the mediation systems, like the Korean Commercial Arbitration Board.

The Chinese Communist Party's 'with-Chinese-characteristics' discourse proclaims its superiority in reflecting people's genuine needs without poisonous partisan politics, as in Western democracies. The Party's Consultative Democracy is key to this superiority. To evaluate Consultative Democracy in Contemporary China from a perspective of popular sovereignty, which is the essential purpose of every kinds of democracy, this research looks into Consultative Democracy from two dimensions: theoretical dimension and institutional dimension. Theoretically, CCP's Consultative Democracy seeks its theoretical sources from their traditional thought as well as from Marxism, and especially emphasizes CCP's leadership to fulfill the consultation results. And through the analysis of various field investigations, we find that there are some prominent problems in grass-roots society's institutional mechanism for Consultative Democracy, such as insufficient connection between institutional innovation and existing legal system, inefficient consultation, insufficient representation of consultative subjects and weak motive force for sustainable development. By legitimizing certain groups or individuals as representatives in their consultative process, CCP can be de-legitimize by containing, dividing or denouncing others so that critics can be co-opted, neutralized or isolated. The CCP's consultative and representational processes are different from taking policy inputs as dialogue or negotiation as in democracies, it is a dynamic, largely one-way process of enforcement and direction with a clear political agenda: maintaining Party hegemony.

This study aimed to explore the patterns of college students' dialogic argumentation in the context of nanotechnology issues, and to compare these patterns based on their idiocentrism and allocentrism. Nanotechnology represents the characteristics of socioscientific issues in that it is widely used in various fields, but at the same time, it includes the likelihood of negative effects. 33 college students who enrolled in science-related course participated in this study. Participants were divided into idiocentric groups and allocentric groups based on the INDCOL scores, and they participated in group discussions on nanotechnology. All discussions were audiotaped and analyzed using the framework of discourse clusters and schemes. Results showed that participating students engaged in dialogic argumentation with the process of exchanging of individual perspectives, exploration of different perspectives, and coordination and negotiation; specifically, they spent most of their time in exploring different values and perspectives regarding nanotechnology. Results also indicated the differences in discourse clusters and discourse schemes between idiocentric and allocentric groups. Allocentric groups more often negotiated to settle on a group decision than idiocentric groups did, and discourse schemes in their negotiation process were slightly different from the ones in idiocentric groups.

In the learning of mathematics, students experience the semiotic activities of representing and interpreting mathematical signs. We called these activities as the representing and interpreting of mathematical signs. On the foundation of Peirce's three elements of the sign, we analysed that students constructed the representamen to interpret the concept of correlation as for the object, "as one is taller, one's size of foot is larger" 4 middle school students who participated the gifted center in Seoul, arranged the statistical data, constructed their own representamen, and then learned the conventional signs as a result of the whole class discussion. In the process, students performed the detailed representing and interpreting of signs, depended on the templates of the known signs, and interpreted the process voluntarily. As the semiotic activities were taken place in this way, it was needed that mathematics teacher guided the representing and interpreting of mathematical signs so that the representation and the meaning of the sign were constructed each other, and that students endeavored to get the negotiation of the interpretants and the representamens, and to reach the conventional representing.
