In this paper, we want to solve the problems that users want to search the progress of attack, continuity of attack, association between attackers and victims, blocking priority and countermeasures by using visualization interface with multi-rotational axis and radial axis structure. It is possible to effectively monitor and track security events by arranging a time series event based on a multi-rotational axis structured by an event generation order, a subject of an event, an event type, and an emission axis, which is an objective time indicating progress of individual events. The proposed interface is a practical visualization interface that can apply attack blocking and defense measures by providing the progress and progress of the whole attack, the details and continuity of individual attacks, and the relationship between attacker and victim in one screen.

The purpose of previous study centered around introducing minerals into bee colonies was to observe the Varrosa destructor mites-repelling effect of minerals ("Pszczelarstwo" 6/2016). The results of research published so far confirmed the purpose of using minerals in the fight against Varrosa infestation. This publication presents partial results of the next stage of research. Using foundation enriched with studied minerals in right proportions leads to diminishing the number of Varroa destructor parasites in bee colonies. It may also contribute to increase in the amount of honey obtained from bees. Foundations with minerals were in most cases correctly filled with larvae, and the new generation of bees didn't show any morphometric or physical-motor aberrations. The effect of minerals in the foundation weakens with time, which requires adequate reaction from the beekeeper. The study showed no negative effect of mineral suspensions added directly to royal jelly of larvae in the swarm cells and worker cells on the development of bees. Additional research was carried out in August and September and led to surprising observations, which are still too early to report. It obliges us to carry out further, extended subject research on a large number of bee colonies in 2017.

Marine sources as potential treatment options for various diseases have been a subject of growing interest. However, information on the anti-inflammatory mechanism employed by Undaria pinnatifida (UP) remains limited. The present study was conducted to investigate the mechanisms of UP on the mast cell-mediated inflammatory response. To determine the pharmacological mechanism of UP in inflammatory reaction, we evaluated the effects of UP on interleukin (IL)-6, IL-8 and tumor necrosis factor (TNF)-α production and nuclear factor-κB (NF-κB) and caspase-1 activation in calcium ionophore A23187 plus phorbol 12-myristate 13-acetate-stimulated human mast cells-1 (HMC-1). The results showed that UP suppressed IL-6, IL-8 and TNF-α production in a dose-dependent manner. Moreover, UP significantly attenuated NF-kB/caspase-1 activation in stimulated HMC-1. Collectively, these findings provide experimental evidence that UP may be a useful candidate for the inflammation-related diseases treatment.

In the rapidly changing information age, as the need for Informatization education increases, it is necessary to further activate Informatization education for adults. First, in terms of lifelong learning, this researcher suggested learner analysis, class subject materialization, and lecture environment confirmation as three things to be considered first before the course is opened. And as a matter to be continuously considered in terms of lifelong learning, this researcher considered that the connection with the next quarter class and the continuity of learning opportunities should be considered. This study attempted to reveal the differentiated characteristics of informatization education in terms of lifelong education by presenting and analyzing three actual class cases taught by this researcher at lifelong education institutions. Its characteristics included customized education in the information age, continuous upgrades of equipment, instructor education in response to the information age, and expansion of employment opportunities. Based on the case of information education classes, this study, which analyzed the differentiated characteristics of information education at the lifelong education level, can help improve the quality of instructors and self-development of learners in the actual educational environment. For this, continuous follow-up research will also be needed.

This study aimed to analyze the coordination of muscle and muscle fatigue between biceps, lateral deltoid, and anterior deltoid during dumbbell side lateral raise using bio-signal. One male subject performed dumbbell side lateral raise with 3% of 1RM dumbbell at the rate of 30bpm until failure (8 minutes). While performing, ECG were recorded to observe the participant's performance. EMG were recorded from biceps, lateral deltoid, and anterior deltoid for observing coordination and fatigue. ECG were analyzed in time and frequency domain to observe Heart rate, normLF, normHF. Changes in heart rate, normLF, and normHF indicate that the sympathetic nervous system is activated, while changes in median frequency (MDF) indicate the occurrence of muscle fatigue. Moreover, the coordination relationship of muscle changed. The correlation of MDF between each muscles indicated that lateral deltoid is associated with biceps and anterior deltoid. These results showed that our study can contribute to improving understanding of muscle fatigue and muscle coordination relationships.

With the rising importance placed on sustainability for brands, a plethora of research addresses consumer responses concerning eco-friendly products. While positive effects of eco-friendly traits on beauty products have been discussed, this study addresses a wide research gap in the makeup category. Based on the goal-attribute theory and the lay theory of ethicality, detrimental effects of eco-friendly ingredient claims on perceived appearance enhancement attributes (AEA) were examined. A between-subject, single-factor (eco-friendly ingredient claims present vs. absent) web-based experimental design tested the effect of conditions on makeup products that emphasized AEA. Results found a negative effect of eco-friendly ingredient claims on perceived AEA, supporting previous literature regarding the 'green gap'. Evidence showed that perceived AEA fully mediated the effect of eco-friendly claims on purchase intention, which was moderated by AEA preference. Interestingly, findings show that the purchase intention of respondents with a near-average preference for AEA was not moderated. Results contribute to preexisting literature by extending the lay theory of ethicality and product function mismatch to the field of makeup. Managerial implications are discussed, including opportunities for eco-friendly makeup products to appeal to alternative benefits.

The purpose of this study is to identify the level of safety perception, ethical awareness, and safety activities of nursing students for patients, and to identify the correlation and impact between them. The research design is a descriptive survey study, and the subject of the study were 197 nursing college students in G City. Safety perception, ethical awareness, and safety activity tools were used for, and the data collection period was from October 17 to 28 in 2022. T-test, one-way ANOVA, Pearson's correlation coefficient, Regression analysis were used to analyze data. The result of the study indicated that the average level of safety perception of nursing students was 3.72 points, the average ethical awareness of patients, professional work, and cooperators perceived by nursing students was 3.04 points, and the safety activities of nursing students were 4.20 points. In the case of safety awareness and ethics awareness, r=.327, a significant positive correlation, in the case of safety awareness and safety activities, r=.399, significant positive correlation, ethics awareness and safety activities as r=.296. And so on these results showed that high safety perception increases safety activities, and high ethical awareness increases safety activities. Therefore, we need practical and step-by-step convergence education to equip nursing students with patient safety nursing capabilities. To this end, a safer environment will be created if the social support network for the systematic application of safety education is well formed.

Approximately 89% of all capsizing accidents involve small vessels, and despite their relatively high accident rates, small vessels are not subject to ship stability regulations. Small vessels, where the provision of essential basic design documents for stability calculations is omitted, face challenges in directly calculating their stability. In this study, considering that the majority of domestic coastal small vessels are of the Chine-type design, the goal is to establish the major hull form characteristic data of vessels, which can be identified from design documents such as the general arrangement drawing, as input data. Through the application of a deep learning approach, specifically a multilayer neural network structure, we aim to infer hydrostatic curves, operational draft ranges, and more. The ultimate goal is to confirm the possibility of directly calculating the initial stability of small vessels.

Product images in online fashion retail play a crucial role in shaping consumers' decision-making processes. This study investigates the effects of product display types (i.e., flat vs. human display) on consumers' purchase intentions and willingness to pay (WTP) in online fashion retailing. Using a basic shirt as the target product, we examine how overall certainty of fit (OCF) is perceived differently based on the product display type, and for which individuals the effect is amplified, considering individual differences in the need for touch (NFT). A one-factor (flat vs. human display type) between-subject experiment was conducted via an online survey platform (N = 212). The results indicated that the flat display mode generates a higher purchase intention than the human display, along with a marginally higher WTP. Additionally, the positive effect of a flat display on OCF was significant for individuals with low NFT. This study extends our understanding of online retail product displays and their influence on consumer behavior, yielding valuable insights for marketers to improve product presentation in online retail environments.
