Cosmic radiation environments having extremely high-energy particles and photons cause severe malfunctions of electrical components in space and terrestrial regions. In this study, we revisit basic knowledge on radiation effects in ICT electrical devices, such as single event effect, total ionizing dose, and displacement damage. To avoid such soft errors and system failures, we introduce essential technical approaches from the perspectives of materials, layouts, circuits, and systems, including current research trends. By considering several techniques and Space EEE part standards, we suggest possible directions that can invoke New Space Era technology.

We investigated technological trends in an electrocardiogram (ECG)-based biometric cryptosystem that uses physiological features of ECG signals to provide personally identifiable cryptographic key generation and authentication services. The following technical details of the cryptosystem were investigated and analyzed: preprocessing of ECG signals, extraction of personally identifiable features, generation of quantified encryption keys from ECG signals, reproduction of ECG encryption keys under time-varying noise, and new security applications based on ECG signals. The cryptosystem can be used as a security technology to protect users from hacking, information leakage, and malfunctioning attacks in wearable/implantable medical devices, wireless body area networks, and mobile healthcare services.

The emergence of generative hyperscale artificial intelligence (AI) has enabled new services, such as image-generating AI and conversational AI based on large language models. Such services likely lead to the influx of numerous users, who cannot be handled using conventional AI models. Furthermore, the exponential increase in training data, computations, and high user demand of AI models has led to intensive hardware resource consumption, highlighting the need to develop domain-specific semiconductors for hyperscale AI. In this technical report, we describe development trends in technologies for hyperscale AI processors pursued by domestic and foreign semiconductor companies, such as NVIDIA, Graphcore, Tesla, Google, Meta, SAPEON, FuriosaAI, and Rebellions.

Decentralized autonomous organizations (DAOs) is an effective and secure means to enable direct collaboration between people who want to achieve common goals in a digital environment, where believing each other without intermediaries from trusted third parties is difficult. DAO can flexibly implement most of the roles previously performed by existing organizations and finally aim for a new structure that functions independently without human intervention. Despite its technical and legal uncertainties and problems, DAO is rapidly expanding. This study examines trends such as the concept, use cases, participation methods, and deficiencies of DAO, which is called the future of work and helps to understand upcoming considerations.

In the rapidly growing field of quantum computing, it is evident that a robust supply chain is needed for commercialization or large-scale production of quantum chips. As a result, the success of many R&D projects worldwide relies on the development of quantum chip foundries. In this paper, a variety of quantum chip foundries, particularly the ones creating photonic integrated circuit (PIC) quantum chips, are reviewed and summarized to demonstrate current technological trends. Global projects aiming to establish new foundries, as well as information regarding their respective funding, are also included to identify the evolutionary direction of quantum computing infrastructure. Furthermore, the potential application of lithium niobate as a novel material platform for quantum chips is also discussed.

The value of living a long and healthy life without suffering has increased owing to aging populations, transition to welfare societies, and global interest in health deriving from the novel coronavirus disease pandemic. New drug development has gained attention as both a tool to improve the quality of life and high-value market, with blockbuster drugs potentially generating over 10 billion dollars in annual revenue. However, for newly discovered substances to be used as drugs, various properties must be verified over a long period in a time-consuming and costly process. Recently, the development of artificial intelligence technologies, such as deep and reinforcement learning, has led to significant changes in drug development by enabling the effective identification of drug candidates that satisfy desired properties. We explore and discuss trends in artificial intelligence for de novo drug design.

Cloud computing technology based on centralized high-performance computing has brought about major changes across the information technology industry and led to new paradigms. However, with the rapid development of the industry and increasing need for mass generation and real-time processing of data across various fields, centralized cloud computing is lagging behind the demand. This is particularly critical in emerging technologies such as autonomous driving, the metaverse, and augmented/virtual reality that require the provision of services with ultralow latency for real-time performance. To address existing limitations, distributed and edge cloud computing technologies have recently gained attention. These technologies allow for data to be processed and analyzed closer to their point of generation, substantially reducing the response times and optimizing the network bandwidth usage. We describe distributed and edge cloud computing technologies and explore the latest trends in their standardization.

In this paper, we analyze the trends of the international shipping market and the domestic and foreign factors of the crisis of the domestic shipping market, and identify the characteristics of the recovery of the Busan New Port trade volume which has decreased since the crisis of the domestic shipping market We quantitatively analyzed the future volume of Busan New Port and analyzed the trends of the prediction and recovery trends. As a result of analyzing Busan New Port container cargo volume by using big data analysis tool R, the variation of Busan New Cargo container cargo volume was estimated by ARIMA model (1,0,1) (1,0,1)[12] Estimation error, AICc and BIC were the most optimal ARIMA models. Therefore, we estimated the estimated value of Busan New Port trade for 36 months by using ARIMA (1, 0, 1)[12], which is the optimal model of Busan New Port trade, and estimated 13,157,184 TEU, 13,418,123 TEU, 13,539,884 TEU, and 4,526,406 TEU, respectively, indicating that it increased by about 2%, 2%, and 1%.

Although it is difficult to predict the future engineers, including optical engineers, must do it on a regular basis. After all, what is the generation of a new optical design, but an attempt to predict what will be needed next year\ulcorner But optical engineers do not consult oracles or look into crystal balls, instead they look at past history, new research, and the trends in technology. This talk will use this approach to look at where optics will take us in this new century. (omitted)

Touch screen using in portable devices is expanding continuously, has become particularly strong in mobile phones. These trends are able to open the "New Horizon" which refers the design and usability of mobile phones and provide "New Experience" which users have never been experienced on mobile phones. This research argues new usability issues and important points which can be occurred in touch based mobile phones as user experience point of view.
