In this paper, we propose schemes of blockchain utilization in tactical communication environment. The military tactical communication environment has similar characteristics with blockchain network such as distributed architecture, decentralization, and the need for data integrity. A communication node constituting a tactical communication network is constituted by a system capable of configuring and connecting a network for each node. When a communication node, having such capabilities, is configured as a node of blockchain network, various functions could be performed. In this paper, we propose utilization schemes of authentication, integrity, record management, and privilege control based blockchain technology. Functions for authentication, integrity verification, and record management need to ensure the stored data and could track history. The requirement of function's characteristics are matched to blockchain which is storing data sequentially and difficult to hack data, so that it could perform functionally and sufficiently well. Functions for authority control should be able to assign different privileges according to the state of the requestor. Smart contract will function when certain conditions are satisfied and it will be able to perform its functions by using it. In this paper, we will look over functions and utilization schemes of blockchain technology which could reliably share and synchronize data in a tactical communication environment composed of distributed network environment.

Due to the difference between the underwater communication environment and the terrestrial communication environment, the radio communication mainly used on the ground cannot be used in underwater. For this reason, in the underwater communication environment, various communication media such as acoustic waves, infrared rays, light and so on has been studied, but there exist several difficulties in operating them individually due to their physical limitations. The concept for overcoming these difficulties is the very underwater multi-media communication, a method to select a communication medium best suitable for the current underwater environment among underwater communication multimedia whenever there occurs underwater communication failure. In this paper, we present an underwater multi-media communication network based on star topology and a fragmentation and reassembly technique to solve the problems caused by the different MTU (Maximum Transmission Unit) sizes among different underwater communication media. We also present the estimations and analysis on processing times in each of fragmentation and reassembly and the total data amount for transmitting fragments in our proposed underwater multi-media communication network.

Effective internal communication is known to have a positive impact on business performance, but there is a lack of research on the effects of online channels for workplace communication. This study using regression analysis examines how task-technology fit, information richness, self-efficacy, perceived ease of use, and perceived usefulness related to online communication channels affect not only the satisfaction with the tools but also the effectiveness of them. Additionally, we verify how the organizational culture of online and offline communication shows the control effect. As a result, all five variables were positively correlated with internal communication channels satisfaction, and we found that the organizational culture of online and offline communication controls the relationship between online communication channels satisfaction and effectiveness.

이 연구는 소설이 허구의 세계이지만 당시의 사회상을 반영한다는 전제에서 9편의 신소설을 통하여 개화기 일반 백성들의 다양한 인간 커뮤니케이션 양태를 분석하였다. 분석 결과 개화기 인간 커뮤니케이션의 가장 큰 특징은 신문과 서적, 우편, 전보, 전화, 사진 등 새로운 매체의 출현으로 커뮤니케이션 환경이 다양화되었다는 점이다. 새로운 매체들이 출현하기는 했지만 아직도 구두 커뮤니케이션에 의존하는 전통적 방식이 중심이 된 것으로 볼 수 있겠다. 구두 커뮤니케이션에서 신분과 연령이 가장 큰 변수가 된 점은 조선 후기와 같았지만 격식과 예법은 많이 완화되었다. 또한 문자 문화의 기반이 대폭 확대되었다. 새로 등장한 매체들도 대부분 문자를 기반으로 하는 것들이며 여성이나 천민 계층에서 한글 사용이 늘어났다. 개항으로 외국과의 교류가 가능해짐으로써 그 시대 사람들의 생활 세계가 확대되며 문화 간 커뮤니케이션도 이루어져 필담이나 통역 등의 형태도 등장하게 되었다. 결론적으로 개화기의 인간 커뮤니케이션 양태는 여전히 구두 커뮤니케이션에 주로 의존하면서도 새로운 미디어에 대한 의존이 점차 높아지기 시작하여 원거리 커뮤니케이션도 신속하게 가능해졌으며 문호 개방에 따라 커뮤니케이션의 영역과 범위도 확대되며 그 방법도 다양해졌다고 평가할 수 있겠다.

We're living in a world of one global village. The globalization of business is acceleration as more companies cross national borders to find customers, materials and money. Many foreign companies and organizations are doing their business aggressively in Korea and many Korean companies and rushing into foreign market. When people communicate for business with someone from another culture, there could be difficult communication barriers to overcome resulting from differences in their values, beliefs, norms for behavior, expectations, attitudes and so on. To do successfully business, we need to understand culture background and communication style that is different from nation, race, language. Communication barriers stemming from cultural differences may vary. Largely, they can be divided into value system, non-verbal communication, and perception process. Value system can be divided into individualism versus group orientation, avoidance of uncertainty degree, power distance, and high- context culture versus low-context culture. Also non-verbal communication method and perception process may play decisive roles in communication effectiveness. Especially nonverbal communication barriers which sometimes play more important roles than the verbal parts are composed of eye contact, gesture, kinesics, proxemics, chronemics, paralanguage and language of color Cross-cultural communication affect business situation. I expect that if we understand cultural background, and then we overcome cross-cultural communication barriers. To overcome and to adapt inter-cultural business, we need to develope curriculum on the cross-cultural education which I will study in the next paper.
