In recent years, attacks on network environments continue to rapidly advance and are increasingly intelligent. Accordingly, it is evident that there limitations in existing signature-based intrusion detection systems. particular, for novel such as Advanced Persistent Threat (APT), signature patterns have problems with poor generalization performance. Furthermore, a environment, attack samples rarely collected compared normal samples, creating the problem of imbalanced data. Anomaly using an...

A conceptual framework proposed in this illustrates appropriation explore how they influence task performance job satisfaction. Most factors, drawn adaptive theory technology acceptance model, were found accelerate appropriation, which consequently raising The usefulness lies its comprehensive approach that...

This study aims to investigate motivational factors and motivation hindering of online shopping via open market platforms. For a comprehensive exploration, the response data were collected from total 417 Korean consumers before conducting hierarchical regression analysis. The results showed that effects on purchasing intention all supported. As for moderating concerns e-commerce, privacy by time saving, perceived ease use, security cost saving found be statistically significant. Privacy...

As education is increasingly going online, propelled by the COVID-19 outbreak, how to build student engagement has become critically important, and it is, therefore, necessary explore motivators barriers comprehensively. Given nature of an online learning environment, this study specifically focused on security privacy concerns as major issues that may be restricting engagement. Based data collected from 296 students studying at Y University, South Korea, reported results structural model...

In sports, virtual spaces are sometimes utilized to enhance performance or user experience. this study, we conducted a frequency analysis, semantic network and topic modeling using 134 abstracts obtained through keyword searches focusing on "Sport(s)" in combination with "Metaverse," "Augmented Reality," "Virtual "Lifelogging," "Mixed Reality." First, the top 20 words were extracted then each type of word was retained select seven words. The analysis revealed emergence key themes such as...

Samsung has announced the development of a full high definition (1920 × 1080) 82″ TFT- LCD panel using Super-PVA (S-PVA) technology, world's largest TFT-LCD. In addition to size breakthrough, this product achieves 600nits brightness, over 1200:1 contrast ratio, 180-degree angle view, 92% color gamut, and 8 msec response time. Several key enabling technologies were developed achieve these specifications, including two transistor direct driven independently controlled S-PVA sub-pixels, non...

As cyberattacks become more intelligent, the difficulty increases for traditional intrusion detection systems to detect advanced attacks that deviate from previously stored patterns. To solve this problem, a deep learning-based system model has emerged analyzes intelligent attack patterns through data learning. However, learning models have disadvantage of having re-learn each time new cyberattack method emerges. The required learn large amount is not efficient. In paper, an experiment was...

Purpose This study aims to examine how exploitation of shared knowledge is related creative behavior by focusing on the roles social contextual factors – perceived co-worker support and relationship conflict. Design/methodology/approach The proposed research model in this posits following: mediates between conflict moderate behavior. For an empirical examination, was tested PLS-SEM using 457 responses gathered from workers different companies Korea. Findings It turned out that fully Also,...

Abstract This study investigates whether a target firm's corporate social responsibility (CSR) performance creates value for shareholders. Our results indicate that CSR is stronger than of the acquirer firm yields higher premiums In addition, positive valuation effect more pronounced when well‐governed acquirers conduct takeover. evidence robust to several sensitivity tests. These imply favorable market reactions target's are due expectation reward shareholders with fair in merger and...

The network intrusion detection system is a core technology of security that detects packets for malicious activities occurring in the and an essential element stable services extended environments such as big data IoT. These systems have been studied together with machine learning deep learning, but performance not guaranteed actual environment or class balance problem has solved. Therefore, this study, we investigate discretization preprocessing method CNN-based classifier on imbalance...

Analytic expressions for radiation force on a sphere in loosely focused Gaussian beam are derived suitable form applications by the photon stream method ray-optics regime. For perfect reflecting spheres, an analytic solution scattering and simplified expression gradient obtained. The computation results presented consistent with those of previous theoretical studies reported experimental results.

Abstract— Samsung has developed a high‐resolution full‐HD (1920 × 1080) 120‐Hz LCD‐TV panel using novel pixel structure and motion‐compensated frame‐interpolation (McFi) single‐chip solution.
