Based on the development of SNS in Mobile and Internet, crisis management is regarded as an important issue that determines the rise and fall of businesses. This study aims to contribute to more efficient implementation of crisis management messages by examining the relationship between the strategy of crisis management communication and the level of specificity of the message. The study found that consumers evaluated the crisis-hit company's acceptance communication strategy to show a higher level of integrity, reliability and appropriateness than the defensive strategy. However, this main effect is mediated by the specificity (high specificity vs. low). Specifically, consumers' assessment of crisis management messages and information-seeking behavior were found to be most favorable when used in a mixture of acceptance strategies and high specificity. Conversely, the lowest effect was the combination of defense strategy and high specificity. Based on these results, the theoretical discussions is described for crisis management practitioners of enterprises and organizations.

With the rapid development of mobile communication technology, the technologies based on the diverse digital modulation schemes have been used for the frequency range of over 800 MHz. The only radiation immunity has been tested using only AM signal based on IEC 61000-4-3 without any consideration of the influence of electromagnetic radiation in Korea. However, it has not been tested by wideband digital modulation signals such as cdmaone(IS-95), WCDMA and PM signal. The purpose of this study was to review the standards. In addition, the input signals were analyzed and tested considering the environments in Korea. The results showed that the devices were influenced by digital modulation signal or PM signal more than by AM signal.

In this paper, we present an automatic image object tracking system for Studio cameras on the stage. For object tracking, we use the OpenCV-based Python program using PC, Raspberry Pi 3 and mobile devices. There are many methods of image object tracking such as mean-shift, CAMshift (Continuously Adaptive Mean shift), background modelling using GMM(Gaussian mixture model), template based detection using SURF(Speeded up robust features), CMT(Consensus-based Matching and Tracking) and TLD methods. CAMshift algorithm is very efficient for real-time tracking because of its fast and robust performance. However, in this paper, we implement an image object tracking system for studio cameras based CMT algorithm. This is an optimal image tracking method because of combination of static and adaptive correspondences. The proposed system can be applied to an effective and robust image tracking system for continuous object tracking on the stage in real time.

Nowadays, as the availability of tiny, low-cost microcomputer increases at a high level, mobile robots are experiencing remarkable enhancements in hardware design, software performance, and connectivity advancements. In order to control Turtlebot 2, several algorithms have been developed using the Robot Operating System(ROS). However, ROS requires to be run on a high-cost computer which increases the hardware cost and the power consumption to the robot. Therefore, design an algorithm based on low-cost hardware is the most innovative way to reduce the unnecessary costs of the hardware, to increase the performance, and to decrease the power consumed by the computer on the robot. In this paper, we present a path-finding algorithm for TurtleBot 2 based on low-cost hardware. We implemented the algorithm using Raspberry pi, Windows 10 IoT core, and RPLIDAR A2. Firstly, we used Raspberry pi as the alternative to the computer employed to handle ROS and to control the robot. Raspberry pi has the advantages of reducing the hardware cost and the energy consumed by the computer on the robot. Secondly, using RPLIDAR A2 and Windows 10 IoT core which is running on Raspberry pi, we implemented the path-finding algorithm which allows TurtleBot 2 to navigate from the starting point to the destination using the map of the area. In addition, we used C# and Universal Windows Platform to implement the proposed algorithm.

Over the past few years, smart devices, including smartphones, have been continuously required by users based on portability. The performance is improving. Ubiquitous computing environment and sensor network are also improved. Due to various network connection technologies, mobile terminals are widely used. Smart terminals need technology to make energy monitoring more detailed for more stable operation during use. The smart terminal which is light in small size generates the power shortage problem due to the various multimedia task among the terminal operation. Various estimation hardwares have been developed to prevent such situation in advance and to operate stable terminals. However, the method and performance of estimating the remaining amount are not relatively good. In this paper, we propose a method for estimating the remaining amount of smart terminals. The Capacity Estimation of lithium ion cells for stable operation was estimated based on machine learning. Learning the characteristics of lithium ion cells in use, not the existing hardware estimation method, through a map learning algorithm using machine learning technique The optimized results are estimated and applied.

The trade war between the United States and China has been going on for many years, and sanctions against Chinese telecommunications companies in the United States are increasingly tightening. Despite these restrictions, ZTE (Zhongxing), China's leading communication equipment company, is rather expanding its market share in the global 5th generation mobile communication (5G) market. ZTE's growth and competitiveness are based on its unique corporate culture. ZTE places great importance on R&D, has a corporate culture of humility and moderation based on traditional Chinese culture. Besides, it has the placement and use of human resources in the right place. While ZTE strives to implement people-centered management, it makes good use of internal competition. Despite ZTE's global market share and corporate competitiveness, virtually nothing has been studied in Korea. The results of this study are intended to be helpful in enhancing the competitiveness of Korea's ICT industry and companies that want to expand to the world while fostering 5G.
