The development of neural networks is evolving towards the adoption of transformer structures with attention modules. Hence, active research focused on extending the concept of lightweight neural network algorithms and hardware acceleration is being conducted for the transition from conventional convolutional neural networks to transformer-based networks. We present a survey of state-of-the-art research on lightweight neural network algorithms and hardware architectures to reduce memory usage and accelerate both inference and training. To describe the corresponding trends, we review recent studies on token pruning, quantization, and architecture tuning for the vision transformer. In addition, we present a hardware architecture that incorporates lightweight algorithms into artificial intelligence processors to accelerate processing.

This study aims at analyzing research trends of library management and suggesting future tasks of this area in Korea. This is a study following the previous study which was done in 2014. For this purpose, this study analyzed 323 papers of library management area among the library and information science papers which have been published from 2014 to 2020 at the four academic journals of the National Research Foundation of Korea. As a result, it was found that 46 papers in library management had been produced annually. The amount of papers in library management has increased, compared to 36 papers annually published which were checked at the previous study. The analysis on the research trends of sub-fields of library management showed that high research performance has been done at the sub-fields like 'general management', 'human resource management', 'measurement and evaluation'. However, there has still been less performance in the sub-fields like 'marketing', 'organization management', 'budget management', which was also shown at the previous study.

Research trends of concrete-polymer composite were analyzed based on 549 papers that were presented at international Congresses on Polymer in Concrete that have been opened seven times all around world since 1975. The analysis revealed that relative quantities of the papers about PC, PCC, PIC and others were 51%, 24%, 13% and 12%, in the order. Basic research was the main stream for PCC, PC, PIC. In PC study, however, it was shown that many researches were actively performed for application of PC.

In this article, I summarize the various academic documents and regulatory agency reports on the Zero-Rating, and describes the type classification, major cases, and policy trends of major countries. In the case of Korea, the lack of academic research and the policy making work are relatively late compared to the advanced countries, so I hope that this paper will be helpful for the development of domestic academic research and policy direction in the future.

The purpose of this study is to suggest development directions and elicit future research themes of U-City and future city by identifying the research trends of U-City theses. For this, meta-keywords were elicited based on the theses of U-City and future city published from mid 1990s to 2010. Centered on the meta-keywords, temporal keyword analysis was performed to compare the research trends of U-City and future city theses in Korea and oversea. The results show that most of U-City and future theses in Korea and oversea mainly dealt with technology. U-City theses in Korea have a tendency to research technology, methodology, service, planning and management in order from the early beginning. However, the U-City and future theses in oversea have a tendency to continuously study U-City applications to city through the model based on the technology and methodology. Therefore, the U-City research in Korea should focus on aspects of urban regeneration, urban scale, and so on. That is to say, the research in near future is required to apply the U-City to various urban themes.

This study aims at reviewing the research trends of records and archives management history published during the past 12 years, analyzing issues, and suggesting future tasks in related research areas. It starts with categorizing research areas of records and archives management history in archival sciences. All 31 articles have been selected from the 2 journals on archival science and 6 journals on related research areas. In quantitative measurement, the paper draws up 31 kinds of article bibliographies and looks at the current status of subject areas by year and author. In content analysis, selected articles are categorized into 3 subject areas, that is, general history, domestic history, and foreign history. For each subject area, research trends of the historical and regional studies are analyzed. This study concludes with emphasis on a new research direction between practice and points out that academic theory should be required for the future development in records and archives management history.

The metaverse is expected to evolve into an immersive environment based on photorealistic stereoscopic imaging to integrate real and virtual worlds. To transition from flat images to immersive stereoscopic images, such as light fields and holograms, a continuous cycle of technological development should be reached in media, content, and device technologies, ranging from acquisition and generation to transmission and synthesis as well as reproduction and interaction. Additionally, owing to the multitude of components involved in the metaverse, proper service realization will be challenging without concurrent advancements in computing and communication technologies that facilitate the integration of such components. We introduce research and development trends in media, contents, and devices at the Electronics and Telecommunications Research Institute toward the next generation of stereoscopic images.

Wearable metaverse devices have sparked enthusiasm as innovative virtual computing user interfaces by addressing a major source of user discomfort, namely, motion-to-photon latency. This kind of latency occurs between the user motion and screen update. To enhance the realism and immersion of experiences using metaverse devices, the vergence-accommodation conflict in stereoscopic image representation must be resolved. Ongoing research aims to address current challenges by adopting vari-focal, multifocal, and light field display technologies for stereoscopic imaging. We explore current trends in research with emphasis on multifocal stereoscopic imaging. Successful metaverse visualization services require the integration of stereoscopic image rendering modules and content encoding/decoding technologies tailored to these services. Additionally, real-time video processing is essential for these modules to correctly and timely process such content and implement metaverse visualization services.

Virtualization technology supports the execution of software unrelated to the hardware environment through the decoupling of software and hardware. Additionally, it enables network slicing, allowing one physical device to be divided and used by a function or service by supporting sharing with isolation. Virtualization enables flexible platform use, allowing a variety of services to be launched without changes or additions to the hardware platform. We describe virtualization technology trends in satellite/mobile communication systems. Basic concepts and technical definitions are included, and the current status of research and development by domestic and foreign organizations, including the Electronics and Telecommunications Research Institute, is analyzed. Finally, future prospects and implications are discussed.
