  • This study aims to describe the overall aspects of future technologies in Korea based on the new taxonomy of technology foresight ; Theme, Area and Paradigm. This taxonomy is designed to overcome and supplement several studies on technology foresights which are judged not to capture the whole aspects of future technologies. Future technologies in Korea will be influenced by the Information and Communication Technology Paradigm over 20-30 years, and by the Biotechnology Paradigm after that period. Expansion of researches in electronics, information and communication is noticeable features in engineering. The application of biotechnology technique and health/environment technologies are emerging in bioscience area. Also there appear new areas related to the trends of engineering and bioscience in natural science. Current research patterns focusing physics, chemistry and engineering in Korea should be changed to those of the advanced countries which emphasize bioscience. Time lag to the world frontier is over 5-6 years, but the lag is expected to be reduced. The shortage of manpower and research funds are pointed as the biggest barrier for the realization of future technologies.

  • The reduction of energy consumption at the base station (BS) has become more important recently. In this paper, we consider the adaptive muting of the antennas based on the predicted future traffic load to reduce the energy consumption where the number of active antennas is adaptively adjusted according to the predicted future traffic load. Given that traffic load is sequential data, three different RNN structures, namely long-short term memory (LSTM), gated recurrent unit (GRU), and bidirectional LSTM (Bi-LSTM) are considered for the future traffic load prediction. Through the performance evaluation based on the actual traffic load collected from the Afghanistan telecom company, we confirm that the traffic load can be estimated accurately and the overall power consumption can also be reduced significantly using the antenna musing.

  • The objectives of this paper were to review the difference between the analog and digital age, and to suggest new communication strategies for Agricultural Extension Service Centers in the digital age. Literature review and discussion on the information age and its supporting technologies, such as the Internet and other digital tools, has enabled communication to occur during time periods and in locations based upon individual needs. With increasing number of internet subscribers using email and the world wide web, the internet is now considered a new mass media for communication, and may soon consider such electronic connectivity as essential in agricultural extension services. Communication strategies in the future should recognize and adapt to the changing needs farmers and extension educators in the information age. Utilization of internet technology and digital tools in communication may attract and retain farmers and extension educators in the future, thus. some of new strategies for communication in agricultural extension services should include the following; 1) traditional linear model should be change into interactive model in communication. 2) Agricultural extension service should include creative role with diffusion process. 3) Agricultural extension service should establish new receiver paradigm and form new partnership with farmer.

  • Wireless sensor networks represent a new and exciting communication paradigm which could have multiple applications in future wireless communication. Therefore, performance analysis of such a wireless sensor network paradigm is needed in complex wireless channel. Wireless networks could be an important means of providing ubiquitous communication in the future. In this paper, the BER performance of uniform distributed wireless sensor networks is evaluated in non-Gaussian noise channel. Using an analytical approach, the impact of Av. BER performance relating the coherent BPSK system at the end of a multi-hop route versus the spatial density of sensor nodes and impulsive noise parameters A and $\Gamma$ is evaluated.

  • It appears that it is possible for us to make a wireless communication of even home-network system within car by integrating with the Ubiquitous such as mobile phone, wireless Internet, GPS and DMB in the future. If the present wireless surroundings within the car are connected with very high-speed wireless network as measurement system for wireless communication surroundings within this car in the future, it will develop the complicated communication conditions such as safe checkup, communication between systems within car, and wireless communication for user entertainment unlike universal communication conditions. Accordingly, there is the necessity of the device that can measure the interference of electric wave, communication speed and communication quality by a kind of each car. This paper aims at making the real measurement device to raise the reliability of each Application for inquiring into the interference about each other in the frequency band used under Telematics surroundings.

  • This research points out the necessity of customized communication education for engineering students in the era of the Fourth Industrial Revolution. This paper also points out such problems of current communication education as presentation and discussion-focused 'Public Speech' exercises, absence of interests about social issues, and lack of interactive communication learning. In general, as the characteristics of their major education, engineering students are not aggressive in self-questioning and active communication rather than their sensitive reaction to the changes of the new era. Considering these characteristics of engineering students, this research emphasizes that future communication education should be deployed from the major-focused thinking to the development of convergent thinking, from the problem-solving to the problem-finding, and from the contentious thinking to the cooperative thinking. In addition, as a class design reflecting future trends, this research emphasizes, firstly the development of cooperative communication education model, secondly active utilization of SMART technology, and lastly the importance of customized-coaching for each student considering their own characteristics and requirements.

  • Purpose: In this research, we develop an effectiveness analysis simulation model using Agent Based Modeling with Communication Effects for the development of a new weapon system. Methods: To describe the future battlefield that has more complexity, we develop Agent Based Modeling to describe communication Effects. We use the communication theory (Path-Loss Model) and the real map. Results: We have compared simulation model with real map and simulation model without real map. The Blue Survival Ratio of simulation model with real map is worse than one without real map since the performance of communication gets lower. Conclusion: There are many studies about the effectiveness analysis of a weapon system. Most of previous researches assumed no communication error. In the real world, however, it's not appropriate assumption. Therefore, this study considers the communication error and shows that it is important factor in the effectiveness analysis.

  • 무선 통신 기술 발전을 통하여 철도환경에서 안정적인 무선 접속과 다양한 통신 기능 제공이 가능함에 따라 철도서비스 고도화의 기반이 마련되었다. 특히, 최근의 무선 통신 기술은 향상된 철도 승객서비스뿐만 아니라 효율적이고 안전한 철도 운영을 가능하게 한다. LTE 기반의 무선통신 기술은 다양한 경제적 혜택과 높은 통신 성능을 철도 산업에 제공 가능함에 따라 세계적으로 차세대 철도 통신 시스템의 후보 기술로 각광받고 있다. 그러나 철도 통신은 열차의 안전한 운행을 위하여 매우 엄격한 철도 통신만의 요구 사항도 존재한다. 본 논문에서는 미래의 철도 통신이 반드시 갖추어야 할 요구사항과 기능을 설명한다. 또한 LTE 무선 통신 기술이 철도 분야의 통신 요구사항을 만족하는지에 대해서도 서술한다. 마지막으로 최근 진행되고 있는 차세대 철도 통합무선망의 국내외 표준화 동향과 구축일정에 대하여 설명한다.
