Text summarization is the task of producing a shorter version of a long document while accurately preserving the main contents of the original text. Abstractive summarization generates novel words and phrases using a language generation method through text transformation and prior-embedded word information. However, newly coined words or out-of-vocabulary words decrease the performance of automatic summarization because they are not pre-trained in the machine learning process. In this study, we demonstrated an improvement in summarization quality through the contextualized embedding of BERT with out-of-vocabulary masking. In addition, explicitly providing precise pointing and an optional copy instruction along with BERT embedding, we achieved an increased accuracy than the baseline model. The recall-based word-generation metric ROUGE-1 score was 55.11 and the word-order-based ROUGE-L score was 39.65.

This paper focuses on the aesthetic ideology and aesthetic style embodied in the work of 'Blue is the Warmest Color' to dissect it and examine the identity and construction of identity as a minority group in a postmodern context. Blue is the Warmest Color is a film that focuses on homosexual emotions in adolescent development, showing the budding love and emotional orientation of a 15-year-old girl's adolescence, and the ecstsy and torment that comes with an awakened consciousness. The evolutionary process of the characters' emotional orientations is dissected, pointing out that the central theme of the film is the concern for fluid identity and self-identity. Through the narrative and the setting of the characters' emotional patterns and the "Body Writing" of women, this paper further examine the typical variability and fragmentation of postmodern identity, and interpret in detail the content, messages and effects of the characters' dialogues in the film to illustrate the way in which the work expresses class and identity differences. The research method is based on textual analysis and theoretical research.

Smart windows are capable of varying their visible light transmittance (VLT) in response to changing environmental conditions. The VLT variability of architectural windows is highly valuable because it enables indoor lighting and energy environments to align with external changes. However, challenges such as high installation costs and assurance of glass visibility have prompted the exploration of alternative solutions, including models incorporating partially applied smart windows., Prior research focused on useful daylight illuminance (UDI) analysis for south-facing office buildings, pointing out suitable areas for smart-window implementation to enhance lighting control. In this study, we broadened this scope by determining optimal smart-window application zones under changing building orientation. Furthermore, we studied the correlation between building orientation and smart-window deployment areas.

X-ray detection has widely been applied in medical diagnostics, security screening, nondestructive testing in the industry, etc. Medical X-ray imaging procedures require digital flat detectors operating with low doses to reduce radiation health risks. Recently, metal halide perovskites (MHPs) have shown great potential in high-performance X-ray detection because of their attractive properties, such as strong X-ray absorption, high mobility-lifetime product, tunable bandgap, low-temperature fabrication, near-unity photoluminescence quantum yields, and fast photoresponse. In this paper, we review and introduce the development status of new perovskite X-ray detectors and imaging, which have emerged as a new promising high-sensitivity X-ray detection technology. We discuss the latest progress and future perspective of MHP-based X-ray detection in medical imaging. Finally, we compare the conventional detection methods with quantum-enhanced detection, pointing out the challenges and perspectives for future research directions toward perovskite-based X-ray applications.

This paper summarized the safety diagnosis method in the field of durability among the structural safety suggested in the safety diagnosis manual of the reconstruction project and analyzed the safety diagnosis case. It is expected to be a reference material for safety diagnosis in the field of durability by pointing out cases that are wrong during existing safety diagnosis and cases where diagnostics are likely to make errors.

The Korean spacecraft for the exploration of Apophis will be equipped with an optical navigation camera with a wide-angle lens. The major purpose of the wide-angle camera is to capture imagery during the rendezvous phase in order to determine the spacecraft's position and the pointing direction relative to the asteroid Apophis. Two potential sciences, however, can be achieved by the wide-angle camera: (1) to measure the high-order gravity terms, and (2) to capture possible ejecting small particles. In this presentation, we will discuss instrument specification and operation scenario required to accomplish the given science objectives.

This study empirically investigates the impact of recent US export controls on China on South Korea's semiconductor exports. We analyze South Korean export data to shed light on the repercussions of US export restrictions on a third country. Our findings reveal a significant decline in Korean semiconductor exports following the October 2022 imposition of US controls. This decline was most pronounced in the memory, discrete devices, and discrete device components subsectors of the semiconductor industry. In addition, we observed a decrease in unit prices, especially for memory semiconductors, pointing to downward pressure on South Korea's high-value-added semiconductor exports. These results provide some evidence of substantial negative impacts of US export controls on South Korea's semiconductor industry, and particularly with regard to its high-tech products.

Since the last years of the twentieth century, the approach to children's literature from ecocriticism has been discussed in academic fora around the world, especially in the US and Europe. In Southeast Asia, with the foundation of the ASEAN Association of Environment and Literature in 2016, there have been scholarly discussions about the capacity of children's literature to enhance ecological awareness in the region. In Vietnam, since the early years of the 21st century, with the increasing reception of ecocriticism from outside, children's literary works have become the subject of ecocriticism. This article examines scholarly works approaching children's literature in Vietnam, pointing out how they elucidate messages about environmental education. By studying Vietnamese ecocritical scholarship of various types including research, commentaries, and criticism on children's literature, this article argues that ecological education is a prominent feature in the relationship between ecocriticism and children's literature in Vietnam. As such, Vietnamese ecocriticism of children's literature shares the prominent argument of international materials on children's literature and ecocriticism, particularly in Southeast Asia.

In this paper, an optical touch panel device is newly proposed, with operating principle based on the optical coupling between a pointing pen having a built-in light source and perpendicularly crossed optical waveguide arrays. In order to enable an external light to couple into a waveguide core, the auxiliary pyramidal structures are introduced into all intersecting points located periodically along optical waveguides. The shape is optimized for minimizing the unwanted propagation loss due to the same structure by a ray tracing method. For the optical waveguide with the size of $50{\times}50{\mu}m^2$, the bottom width, height, and slope angle of the optimized pyramidal structure are $50{\mu}m$, $22.5{\mu}m$, and $42^{\circ}$, respectively. The optical coupling efficiency of about 97.8% and the average propagation loss of 0.3 dB/mm were achieved for the optimized touch panel. Finally, it is found from the tolerance analysis that tilting of the pen up to ${\pm}12^{\circ}$ can be allowed.
