In this study, we introduce trends in and the future of digital personal assistants. Recently, digital personal assistants have begun to handle many tasks like humans by communicating with users in human language on smart devices such as smart phones, smart speakers, and smart cars. Their capabilities range from simple voice commands and chitchat to complex tasks such as device control, reservation, ordering, and scheduling. The digital personal assistants of the future will certainly speak like a person, have a person-like personality, see, hear, and analyze situations like a person, and become more human. Dialogue processing technology that makes them more human-like has developed into an end-to-end learning model based on deep neural networks in recent years. In addition, language models pre-trained from a large corpus make dialogue processing more natural and better understood. Advances in artificial intelligence such as dialogue processing technology will enable digital personal assistants to serve with more familiar and better performance in various areas.

Following the global air-traffic market growth outlook, urgency of technical development is needed in responding to changes in the international air-traffic management paradigm and to prepare technology securing and spreading strategies, which are consistent with systematic aviation weather service policies and evolution direction. Although air traffic has decreased significantly due to COVID-19, normalcy is expected from 2024, as announced by IATA. According to the future air transportation market outlook and development trends of related technologies, Korea has established and implementing the next-generation air transportation system construction plan(NARAE) to secure international competitiveness and leadership in the future. Therefore, this paper describes the technical, economic background and requirements of numerical model-based aviation weather R&D projects for successful implementation of domestic NARAE plans and providing aviation safety and air traffic service efficiency. Furthermore, we proposed numerical-model-based technology development content, strategies and detailed load-map.

In response to diverse external stimuli, sensory receptors generate spiking nerve signals. These generated signals are transmitted to the brain along the neural pathway to advance to the stage of recognition or perception, and then they reach the area of discrimination or judgment for remembering, assessing, and processing incoming information. We review research trends in neuromorphic sensory perception technology inspired by biological sensory perception functions. Among the various senses, we consider sensory nerve decoding technology based on sensory nerve pathways focusing on touch and smell, neuromorphic synapse elements that mimic biological neurons and synapses, and neuromorphic processors. Neuromorphic sensory devices, neuromorphic synapses, and artificial sensory memory devices that integrate storage components are being actively studied. However, various problems remain to be solved, such as learning methods to implement cognitive functions beyond simple detection. Considering applications such as virtual reality, medical welfare, neuroscience, and cranial nerve interfaces, neuromorphic sensory recognition technology is expected to be actively developed based on new technologies, including combinatorial neurocognitive cell technology.

Future mobile services will require data transmission rates of 100 Gbps or higher due to the universalization of virtual and augmented reality devices. Therefore, THz technology, which uses an ultrahigh frequency band of 200 GHz or higher, is expected to be a candidate for such high-quality services. This article describes the current status of THz radio propagation characteristics, device and system developments, and network requirements to identify the overall trends in THz wireless communication technology.

Korea has pursued economic development based on ICT through R&D policy incorporating CDMA. However, the future society of the Fourth Industrial Revolution is expected to include a new type of industrial development that combines ICT with the non-ICT industry, making it impossible to secure national competitiveness without the source technology of the ICT industry. Therefore, in this thesis, we examine the ICT industry and ICT R&D policy from the point of view of the current ICT as a future source technology source of Korea, and identify strategies to determine ICT as a future technology source through a SWOT analysis.

Two main technologies of III-V/Si laser diode for optical communication, direct epitaxial growth, and wafer bonding were studied. Until now, the wafer bonding has been vigorously studied and seems promising for the ideal III-V/Si laser. However, the wafer bonding process is still complicated and has a limit of mass production. The development of a concise and innovative integration method for silicon photonics is urgent. In the future, the demand for high-speed data processing and energy saving, as well as ultra-high density integration, will increase. Therefore, the study for the hetero-junction, which is that the III-V compound semiconductor is directly grown on Si semiconductor can overcome the current limitations and may be the goal for the ideal III-V/Si laser diode.

연구실안전법에 따라 모든 연구실은 주기적으로 안전점검과 정밀안전진단을 통해 안전을 확보하고 안전환경 상태에 따라 미흡한 평가등급을 받으면 연구 활동에 제약을 받는 제도가 시행되고 있다. 하지만 현재의 점검 및 진단제도는 안전분야별 각 점검항목에 대해 양호, 주의 및 불량 등 이상 3가지로만 평가하고 있으며 각 점검항목에 대해서도 안전에 미치는 영향에 따른 가중치가 고려되지 않아 평가 대상 연구실에 대한 종합적인 안전수준을 확인하는 데 한계가 있다. 이에 연구실 안전전반에 관한 점검항목을 추가하고 평가기준도 가중치를 고려하여 평가결과가 정량적인 점수로 도출될 수 있도록 개선하여 연구주체자가 평가점수를 향상해감으로써 연구실 안전수준을 향상해 갈 수 있도록 방법을 제안해 보고자 한다.
