So far, Korean command post vehicles(CPs) have used voice-only radio communication among the mechanized troop units such MBTs and IFVs, etc. But digital data communication technology should be introduced to improve mission success capabilities and accommodate integrated combat capabilities through increasing SA(situation Awareness), or spatiotemporal synchronization of military operation in battle field environment. Therefore, conventional CPs, which have been operated without digital network, urgently needs to mount a battle management system which furnish with tactical information network, considering that korean new MBTs or new IFVs will be fielded soon. This study suggests some performance enhancement method which might be applicable to CPs which have a role of connecting Battalion unit to Brigade C4I system.

The multistakeholder model of Internet governance is based on the belief that the stakeholder groups should be able to agree on the rules and principles in governing the Internet space. The global expansion of the sweeping influence of the Internet has heightened the awareness of international governments on the importance of Internet governance, but since the Internet has developed mostly through voluntary participation by various groups, the organization with the greatest ability to manage the Internet space currently is ICANN(Internet Corporation for Assigned Names and Numbers), the U.S. based organization that manages the assignment of Internet domain names and IP addresses. Although ICANN has attempted to globalize its operation, governments in some nations are voicing dissatisfaction over the fact that the voice of the governments are not adequately represented within ICANN. This paper examines how the concept of multistakeholderissm has been used in WSIS(World Summit on Information Society), ICANN(Internet Corporation for Assigned Names and Numbers) and the ITU(International Telecommunication Union) as an important principle in emphasizing their roles in Internet governance.

W3C announced a standard software architecture for multimodal context-aware middleware that emphasizes modularity and separates structure, contents, and presentation. We implemented a distributed multimodal interface system followed the W3C architecture, based on SCXML. SCXML uses parallel states to invoke both XHTML and VoiceXML contents as well as to gather composite or sequential multimodal inputs through man-machine interactions. We also hire Delivery Context Interface(DCI) module and an external service bundle enabling middleware to support context-awareness services for real world environments. The provision of personalized user interfaces for mobile devices is expected to be used for different devices with a wide variety of capabilities and interaction modalities. We demonstrated the implemented middleware could maintain multimodal scenarios in a clear, concise and consistent manner by some experiments.

As the number of visually impaired people steadily increases, interest in independent walking is also increasing. However, there are various inconveniences in the independent walking of the visually impaired at present, reducing the quality of life of the visually impaired. The white cane, which is an existing walking aid for the visually impaired, has difficulty in recognizing upper obstacles and obstacles outside the effective distance. In addition, it is inconvenient to cross the street because the sound signal to help the visually impaired cross the crosswalk is lacking or damaged. These factors make it difficult for the visually impaired to walk independently. Therefore, we propose the design of an embedded system that provides traffic light recognition through object recognition technology, voice guidance using TTS, and upper obstacle recognition through ultrasonic sensors so that blind people can realize safe and high-quality independent walking.

Objective : The purpose of this study was to investigate the awareness and availability on items of 2018 assistive devices distribution program for the disabled in the occupational therapists. Methods : A total of 132 occupational therapists participated in the survey from May 1 to May 31. Results : 96.2% of the occupational therapists responded that assistive device is helpful in lives of the disabled people. Especially, they responded that assistive device is the most helpful in 'movement and mobility'. Awareness on an angle spoon/fork with built-up handle and universal cuff was the highest, while a visual signaling indicator was the lowest. Availability on an air cushion was the highest, while a visual signaling indicator and a voice guidance system were the lowest. 67.4% responded that 'sometimes' they use the assistive device and 77.3% responded they will utilize the assistive device. To improve awareness and availability, 43.2% needed financial support, 32.6% needed to add insurance bill and 22.7% needed related education. Conclusion : In the future, this result will be available as a basic data for the education about assistive device for the occupational therapists.

As CAS, X-ATK, and INT models considered as the most typical Air-to-Ground operation models in ROKAF are mainly designed as the voice-centered system between aircraft and ground control facilities, it is critical to newly develop the Link-16 based model for the ROK-US combined operation between F-15K, AWACS, M-SAM, and KDX-III equipped with Link-16. Former studies had been limited to the CAS operation, and they had mainly focused on reducing the voice transmission time to exchange the information between each mission step with maintaining existing operation steps. Therefore, this paper makes up the weak point in former studies, thereby designing new Air-to-Ground operation model for CAS, X-ATK, INT mission using Enterprise Architecture OV6c, which enables both aircraft and ground control facilities or between aircraft to obtain the real-time information on the location, identification, armament and the real-time image data through the broadcasting function. Based on the analysis of new operation model, we come to a conclusion that by simultaneously exchanging the information on mission between nodes concerned through the broadcasting function of Link-16. It is possible to cut down superfluous steps among the mission steps, and to reduce the mission time. It is clear that it gives rise to improve the battle efficiency and the decision-making tempo as well as the battlefield situational awareness.
