인터넷 보안문제 해결을 위해서 침입탐지 시스템 및 바이러스 백신 등이 연구되어 왔고, 생체면역을 응용한 보안체계가 연구되고 있으나, 컴퓨터 자원소비와 비실시간대응의 문제점을 가지고 있다. 이에 Antibody Layer[1]는 인공면역과 Host alliance를 기반으로 하여 보안문제 해결에 효율성과 정확성을 제공하였다. 본 논문에서는 Antibody Layer의 Host alliance를 위한 Cooperation Protocol에 대하여 논하였다.

This paper uses social network theory and the internationalization process model (IPM) to determine how external network linkages influence the location choices of multinational enterprise from emerging economies (EMNEs); specifically, whether past alliance experience influences location choices and its impact on the subsequent entry of MNEs from emerging economies. This paper applies survival analysis using initial and secondary investments from 2,000 Chinese A-share listed companies that entered 90 countries between 1997 and 2018 to analyze both the initial and subsequent entries of Chinese outward foreign direct investments (OFDIs) in major host countries. The findings indicate that an MNE's previous experience with a company from a particular country will increase the likelihood of an initial investment in that country. Previous alliance experience may accelerate the foreign investment process of EMNE and stimulate firms making a commitment to a position in a foreign network, regardless of cultural distance and stage of internationalization. Alliance before initial investment may increase the likelihood and speed of entering a host country as wholly owned subsidiaries and that network linkages not only significantly influence the internationalization process of small and medium-sized enterprises, as indicated by the IPM, but also that of large listed firms.

5G goes beyond people to serve indoor and outdoor companies and industries, as well as campuses such as halls, industrial complexes, educational institutions, stadiums, dense urban areas, rural areas, and government institutions. Therefore, a new approach to small cells is needed. Accordingly, 3GPP and Small Cell Forum are researching 5G small cell architecture; 3GPP, Small Cell Forum, and 5G Alliance for Connected Industries and Automation are also researching private networks tailored to meet the specific requirements of various companies and local governments. In particular, in the UK, a small cell-based technology is required for realizing the Joint Operator Technical Specifications-Neutral Host In-Building specification to cost-effectively secure indoor coverage. Further, the research on the SON(Self-Organizing Network) technology for small cells in 5G, where commercialization has begun, is required. The 5G-based small cell structure, private network, and Neutral Host In-Building and SON reviewed in this study are at the initial research stages; therefore, additional research is needed to secure the competitiveness of the small cell technology in 5G and Beyond 5G.

기존의 침입 탐지 시스템(Intrusion Detection System)은 점점 복잡해져 가는 네트워크, 다양화되고 지능화되는 해킹 기술과 바이러스의 공격으로부터 시스템을 보호하기 위해 처리해야 하는 정보의 양과 복잡한 알고리즘으로 인해 실시간 서비스의 구현이 힘들다는 문제점이 있다. 본 논문에서는 시스템, 네트워크 리소스의 효율적인 분배를 통해 실시간으로 침입자를 탐지할 수 있는 네트워크 토폴로지 즉, 디지털 면역 네트워크(Digital Immune Network, DIN)를 제시한다. DIN은 침입의 탐지를 위하여 생체 면역 시스템의 B세포, T세포 개념의 알고리즘이 적용되고, 견고성 향상을 위해 메쉬 네트워크 구조가 적용되어 호스트 연합(Host Alliance)을 구성함으로써 호스트들의 병렬처리를 통해 리소스 낭비를 막고 실시간 서비스가 제공될 수 있도록 하였다.

Wireless Docking system can provide enhanced convenience to user experience of handheld device such as smart phone by using previously deployed peripheral devises such as monitor and keyboard. In this environment, user can easily use the handheld device with variable peripheral devices at any docking system place. This system would be composed of peripherals except host computing device contrarily to previous desktop and laptop environment. For this system, Wi-Fi Alliance has been developing standard technology based on Wi-Fi Direct(Wi-Fi Peer-to-Peer Technical Specifications v1.2, 2010) technology. However, this system can make a problem which may lead to complex connectivity on handheld device due to non-compatible communication interface. To address given problem, we designed a new method of Bluetooth tunneling technology via previous Wi-Fi Direct communication, and evaluated it with experiment results.

Although international construction market gradually takes a important position among the export industries, the previous studies about international construction entry strategy have just focussed on trend investigation or suggestion for revitalization. Moreover, in order to prepare the market uncertainty such as world financial crisis and to plan the long term strategy, specific strategy studies based on corporate level are required. Therefore, this study estimates the nine strategic index and four financial index of 31 companies that performed 1920 international projects from 1993 to 2007 and evaluate the performance as three periods by multi-regression analysis. Also, this study analyze dynamic correlation between these index and the performance considering times. this study verifies that market diversification, product diversification, localization and decrease of debt to asset ratio make a good effect on the international order as long term strategy and shows that collaborated entry with domestic corporations, alliance entry with host country's company, alliance entry with third country's company, portion of labor cost and portion of management expense differently make a influence on the performance as times. these results will be helpful for the construction companies to plan the international entry strategy reasonably and specifically.

The purpose of the study was to conduct a text mining examining keywords related to the National Paralympics and provide the fundamental information that would be used to change perception of people without disabilities toward disabilities and to promote the social participation of people with and without disabilities in the National Paralympics. Social big data regarding the National Paralympics were retrieved from news articles and blog postings identified by search engines, Naver, Daum, and Google. The data were then analysed using R-3.3.1 Version Program. The analysing techniques were cloud analysis, correlation analysis and social network analysis. The results were as follows. First, news were mainly related to game results, sports events, team participation and host avenue of the 33rd ~ 36th National Paralympics. Second, search results about the 33rd ~ 36th National Paralympics between Naver, Daum, and Google were similar to one another. Thirds, the keywrods, National Paralympics, sports for the disabled, and sports, demonstrated a high close centrality. Further, degree centrality and betweenness centrality were associated in the keywords such as sports for all, participation, research, development, sports-disabled, research-disabled, sports for all-participation, disabled-participation, sports for all-disabled, and host-paralympics.

International sports events is one of the core products in the sports industry. The increasing number of nations are bidding to host the international sports event such as Olympics Game because of expecting to development of a city or nation. Hosting a international sports events are inter-connected and affected by system of socials, politics, cultures and economics. As the scale of the international sports events became larger, sports events process importance is growing. The purpose of this study was build a model of the sports event process in the attract steps. By analyzing event process in the attract steps, the core processes(1. Search, 2. Applications, 3. Practice, 4. Follow-up management) was set and stakeholders and function were analyzed. The modeling was used as IDEF method.
