The purpose of this paper is to give some crisis communication strategies for effective cooperation and coordination among the countries in global society. Based on the theoretical discussions, in this paper, five strategic recommendations toward improving crisis communication are offered as follows; First, it is necessary that a small, dynamic team for global crisis communication function be established among the nearby countries. Second, for understanding the neighboring country's crisis situation, it is needed that the common crisis communication organizations which play an important role of disseminating accurate information and giving the collaborative efforts in each country have to be made. Third, for effective crisis management, an appropriate infrastructure that includes open and effective communication channels among different levels and across organizations must be in place. Fourth, mass communication should fulfill a variety of functions in society and provide information, interpretation of events, and its influence, etc for cooperating and coordinating the crisis management. Fifth, to acquire a correct understanding of the bordering country's crisis and calamities, intercultural education program should be established in the crisis communication system.

CBTC (Communication Based Train Control) is a railroad system, using wireless communication for data transmission between on-board units and ground units, that makes ground computer periodically collect position and speed data from each train and transmits the preceding train's distance data up to speed limit point so as to make on-board control unit control the optimum train speed. Due to the fact that wireless communication system for train control employs only limited frequency band and output frequency, a number of ground communication units should be installed at track-side; also a running train should carry out Handover function which maintains the communication by accessing a new communication channel of the adjacent on-board communication units in accordance with the output of received radio wave. Especially CBTC is largely dependent on Handoff function between ground communication units. Therefore, this paper provides the method of identification of hazard between ground communication units and on board units.

Politics is defined as who gets what, when, and how. Communication is defined as the process, outcomes and effects of message transmission through a medium. Thus political communication in Asia, the most dynamic and uncertain region of the world, has been very dense, requiring rigorous scientific analysis and culturally sensitive reflection. Mass media brought about a revolution in political communication in the last century. In the 21st century, complex monitory devices from the state and international organizations and from the society and transnational groups have transformed the features of political communication. It has triggered another revolution in political communication. Illustrations are given focusing on Asia. A theoretical reflection from the angle of political science is attempted focusing on political communication medium and its effects. I compare no medium (face-to-face communication), mass media, and social media in relation to their effects.

Energy consumption is an important index in mobile ad hoc networks. Data packet transmission increases among nodes, particularly in big data communication. However, nodes may be unable to transmit data packets because of energy over-consumption. Consequently, information may be lost and network communication may block. While opportunistic network is a kind of mobile ad hoc networks, researchers do not focus on energy consumption in opportunistic network communication. This study proposed an effective sensor energy supply scheme that can be applied in opportunistic networks. This scheme considers nodes sensor requests and communication model. In this scheme, nodes do not only accomplish energy supply in communication, but also extend communication time in opportunistic networks. Compared with the Spray and Wait algorithm and the Binary Spray and Wait algorithm in simulations, the proposed scheme extends communication time, increases data packet transmission, and accomplishes energy supply among nodes.
