Due to limited radio resource, an effective paging strategy is essential for improving the utility of radio channels. In current mobile communication networks, when a mobile-terminated call occurs, the network locates the mobile by paging all cells within the location area simultaneously. In this study, we introduces paging strategies that can page some cells or only one cell within the location area to reduce paging cost on radio channels using paging agents. We propose another new paging strategy that can page only one cell within the location area and may have better performance. We also compare the performance of our proposed paging strategy with the performance of the current simultaneous paging strategy and some new paging strategies using paging agents. This paper suggests the most effective paging strategy using mathematical models. The result of this research will be used to select a proper paging strategy in the mobile communication networks.

With the rapid evolution of communication technology, it became possible to overcome the spatial and temporal limitations faced by humans to some extent. Furthermore, the quality of personal life was revolutionized with the emergence of the personal communication device commonly known as the smart phone. In terms of defense networks, however, due to restrictions from the military and security perspectives, the use of smart phones has been prohibited and controlled in the army; thus, they are not being used for any defense strategy purposes as yet. Despite the current consideration of smart phones for military communication, due to the difficulties of network configuration and the high cost of the necessary communication devices, the main tools of communication between soldiers are limited to the use of flag, voice or hand signals, which are all very primitive. Although these primitive tools can be very effective in certain cases, they cannot overcome temporal and spatial limitations. Likewise, depending on the level of the communication skills of each individual, communication efficiency can vary significantly. As the term of military service continues to be shortened, however, types of communication of varying efficiency depending on the levels of skills of each individual newly added to the military is not desirable at all. To address this problem, it is essential to prepare an intuitive network configuration that facilitates use by soldiers in a short period of time by easily configuring the strategy network at a low cost while maintaining its security. Therefore, in this article, the author proposes a Zigbee-based local strategic network by using Opnet and performs a simulation accordingly.

세계 자동차산업은 제품 결함, 비윤리적 기업경영과 같은 다양한 위기를 겪어왔다. 본 연구는 세계 시장에서 가장 큰 비중을 차지하는 중국 소비자를 대상으로 자동차기업의 위기 커뮤니케이션 전략의 효과성을 검증하기 위해 위기책임성, 위기유형과 위기커뮤니케이션 전략이 기업태도, 부정적 커뮤니케이션 의도, 불매운동 참여의도에 미치는 영향을 분석하였다. 서울에 거주하는 중국인 학생 1,600명을 대상으로 2(위기책임성: 고·저) × 2(위기유형: 기업 능력/사회적 책임감) × 2(위기커뮤니케이션 전략: 수용/방어) 설계 실험을 실시하였다. 높은 위기책임성과 사회적 책임감 위기유형은 비호의적 기업태도, 높은 부정적 커뮤니케이션 의도와 불매운동 참여의도로 연결되었다. 위기책임성과 위기커뮤니케이션 전략은 유의한 상호작용을 보였다. 위기책임성이 높을 경우에는 수용 전략이 방어 전략보다 더 효과적으로 나타났으나 위기책임성이 낮은 경우에는 전략 간의 차이가 나타나지 않았다. 기업의 사회적 책임감 위기 경우에는 위기책임성에 상관없이 전략간 차이가 나타나지 않았고, 기업 능력 위기경우에는 위기책임성이 높을 때 수용 전략의 효과가 효과적으로 나타났다.

본 연구는 노무현 대통령 탄핵 사건을 통해 위기를 맞이한 한나라당과 민주당의 위기 상황을 살펴봄으로써 정당별 위기관리의 특징을 살펴보았다. 정당의 위기관리를 위해 각 정당이 사용하는 이미지 회복 전략의 모습을 베노이트(Benoit)의 수사학적인 이미지 회복 전략의 틀로서 분석했다. 그 결과 한나라당과 민주당 모두 비난자 공격을 주로 사용하는 전략을 사용하였으나 위기관리에 성공한 한나라당과 실패한 민주당은 이미지 회복 전략상 차이를 보여줬다. 위기관리에 성공을 거둔 한나라당의 경우 비난자 공격 전략을 주로 사용하다가 미래 지향 전략으로 선회하였다. 따라서 위기관리에 성공한 야당과 실패한 야당을 비교분석함으로써 위기에 대한 책임이 높은 조직은 미래지향적인 전략을 사용하는 것이 바람직하다는 쿰즈(Coombs)의 이론을 뒷받침할만한 모습을 한나라당의 이미지 회복 전락에서 살필 수 있었다.

This paper selected 'Line', the messenger application of Korea's leading software-based IT company 'Naver', and performed a case analysis specially in the early stages of the messenger industry. First, this study analyzed what the mobile messenger industry is and the external environment. Next, an internal analysis was carried out through the strengths and weaknesses through Naver Line's resources and capabilities. With this analysis, this study could evaluate the platform strategy, communication strategy, and the user basic strategy that Naver is carrying out. This study gave us more understanding of the mobile instant messenger (MIM) industry and understand Naver's growth strategy, which will provide great implications for the working staff of IT companies.

This article investigates the distributed data storage problem in the space information network (SIN) using distributed fountain codes. Since space nodes in the SIN are resource-limited, in order to reduce energy consumption while improving the storage reliability, an efficient distributed storage based on fountain codes and probabilistic broadcasting (DSFPB) strategy is proposed. In the proposed strategy, source packets are disseminated among the entire network according to probabilistic broadcasting (PBcast), and the final degree distribution is close to the desired robust soliton distribution (RSD), this is benefited from the appropriate packets encoding procedure of the proposed strategy. As presented by the analysis and simulations, the total cost of data dissemination is greatly reduced compared with existing representative strategies, while improving the decoding performance.

This study presents the Analytical Hierarchy Process (AHP) as a potential decision-making method for obtaining the relative weights of alternatives through pairwise comparison in the context of hierarchical structure. The aim of this study was to elicit prior strategies for brand communication for Korean restaurants overseas. We created a questionnaire and surveyed experts at government agencies, restaurant companies, and universities from October to November 2011. By applying the pairwise comparison matrix, relevance was perceived as a more important strategy evaluation criteria than effectiveness or urgency. The highest-ranked strategy was the 'Identification of the BI and positioning of Korean restaurants' followed by 'Development of Korean food content for overseas promotion', 'Development of locally customized Korean food recipes and new Korean menus', 'Development of marketing communication strategies for Korean restaurants by countries', and 'Development of Korean restaurant differentiation strategies'. The results of this study can be used for effective Korean food globalization by enhancing the competitiveness in the world market.
