The main purpose of this study is to understand the marketing approaches and strategies that are used to disseminating biodegradable fishing gears and distinguish the cognition and the non-cognition group's attitudes on the product. We used a technology acceptance model for analyzing product attributes and its impacts on fishers' purchase. The result of this research shows that 'perceived usefulness and easiness of use' have positive effect on 'purchase intention,' and then give impacts on 'purchase intention' for the entire respondents. For the cognitive respondents these factors have influence on 'attitude' but they do not affect 'purchase decision.' However, 'perceived usefulness and easiness of use' have much positive impact on 'purchase intention.' In the non-cognition group, the 'perceived intention' and 'company and country of manufacturers' have direct positive effect on 'purchase intention' through 'attitude' and also 'on 'purchase intention.' This research provides some meaningful policy implications on further development and technology marketing of biodegradable fishing gears.

In order to reduce the spread of illegal digital contents, many studies have been focusing on how to stop it through laws and regulations. Only few of the studies tried to explain the illegal behaviors from individual's viewpoints. This paper aims to examine the intention of sharing illegal digital contents over the Internet and proposes a theoretical model based on the Theory of Planned Behavior (TPB) along with the introduction of two outcome expectations. We also argue that the individuals' cognition of online copyright will influence individuals' illegal contents sharing on the Internet. We have collected data from online survey and offline interview. By empirical study, the results support the theoretical model except the subjective norm which has no effect on individuals' behavior. This is a different finding from the previous researches revealing that the subjective norm has no effect on individuals' unethical actions. Overall, the findings provide strong confirmation that attitude, self-efficacy and outcome expectations impact on individual's intention of sharing illegal contents. In addition, this study proposed an improved cognition of online copyright through education and standard of new media management will reduce illegal contents sharing on Internet.

This paper delves into the symbiotic integration of coding and mathematics education, aimed at cultivating computational thinking and enriching mathematical problem-solving proficiencies. We have identified a corpus of scholarly articles (n=38) disseminated within the preceding two decades, subsequently culling a portion thereof, ultimately engendering a contemplative analysis of the extant remnants. In a swiftly evolving society driven by the Fourth Industrial Revolution and the ascendancy of Artificial Intelligence (AI), understanding the synergy between these domains has become paramount. Mathematics education stands at the crossroads of this transformation, witnessing a profound influence of AI. This paper explores the evolving landscape of mathematical cognition propelled by AI, accentuating how AI empowers advanced analytical and problem-solving capabilities, particularly in the realm of big data-driven scenarios. Given this shifting paradigm, it becomes imperative to investigate and assess AI's impact on mathematics education, a pivotal endeavor in forging an education system aligned with the future. The symbiosis of AI and human cognition doesn't merely amplify AI-centric thinking but also fosters personalized cognitive processes by facilitating interaction with AI and encouraging critical contemplation of AI's algorithmic underpinnings. This necessitates a broader conception of educational tools, encompassing AI as a catalyst for mathematical cognition, transcending conventional linguistic and symbolic instruments.

The purpose of this study was to investigate effect of methanolic extracts of 10 kinds of wild vegetables cultivated in Gangwon province on antioxidant activity, acetylcholinesterase, and β-secretase inhibitory activities. Results showed that among the wild vegetables, Aralia elata(Miq.) Seem shoot extract exhibited the highest total phenol content (84.65±1.08 mg GAE/g) and total flavonoids content (70.77±0.55 mg RE/g), respectively. The antioxidant activity of wild vegetables extracts was measured by using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay. Aralia elata(Miq.) Seem shoot extracts had the highest DPPH and ABTS scavenging activity (90.16%, 40.18% at 2 mg/mL). As a result, Aralia elata(Miq.) Seem shoot extract was the most effective in terms of acetylcholinesterase inhibitory activity (35.94% at 1 mg/mL). In the β-secretase activity assay, all 10 kinds wild vegetables extracts showed low inhibitory activity, and Aralia elata(Miq.) Seem shoot extract had highest inhibitory activity among the 10 wild vegetables extracts was 14.99%. Taken together, these results showed that Aralia elata(Miq.) Seem shoot extract has potential cognition improvement impact, suggesting that it may provide an effective strategy for improving cognition.

The purpose of this study was to determine the relationship between activities of daily living and health-related quality of life in ambulatory stroke patients. This was a cross-sectional survey study of 60 patients who had survived one year or more after a stroke in community. Activities of daily living were assessed using the Functional Independence Measure (FlM) and health-related quality of life using the Stroke Impact Scale (SIS). The association between FIM and SIS was examined using Pearson' s correlation. The FIM score was higher than the SIS score. Most domains of FIM exhibited a high rate (45-85%) of ceiling effects. However, only the communication and memory domain of SIS exhibited of ceiling effects. The correlation coefficients were .835 (p<.01) for FIM-motor vs. SIS-ADL, .257 (p<,05) for FIM-motor vs. SIS-communication, .596 (p<.01) for FIM-motor vs. SIS-social participation, .635 (p<.01) for FIM-cognition vs. SIS-memory, .369 (p<.01) for FIM-cognition vs. SIS-ADL, and .289 (p<.05) for FlM-cognition vs. SIS-social participation. In conclusion, the correlation between FIM-motor and SIS-social participation was higher than that of FlM-cognition and SIS-social participation. The domains of emotion and hand function of SIS showed no correlation coefficients with FIM-total. To examine the activities of daily living and the quality of life in ambulatory stroke patients in community, it is necessary to use both the FIM and SIS.

In this study, high school students' perceptions of chemically ill-defined ‘heavy metals’ were examined through questionnaires. Nineteen classes of 11th graders (N = 611) were divided into two groups according to completion of 'Chemistry I', which were 10 science-classes and 9 liberal art-classes and compared each other. Three terms of students' cognition and definition, impact on the formation of their cognition, and their chemical knowledge of 'heavy metals' were analyzed by SPSS. The findings revealed that most of students recognized ‘the heavy metal’ as the metal which causes to be accumulated on any living thing and is hazardous in human body regardless of different major between liberal art and science. Mass media and school instruction were found to be the greatest impact on the formation of these cognitions. Especially, school instruction had more effects on students majoring in science than students majoring in liberal art, which bring the result that students in science-classes have more misconception about the definition of 'heavy metals' with human toxicant regardless of metal species and its content in human body and physical density due to the ill-defined terminology of the textbook than students in liberal art-classes do. It is interesting that students in science-classes understood hazard and chemical structure of 'heavy metals' better, while students in liberal art-classes answered the question better about hazardous properties of heavy metals.

Focused on the fact that sound is one of the important sensory cues delivering situations such as impact, this paper proposes an auditory interaction design approach for virtual environment. Based on a few sampling of basic material sound for various materials such as steel, rubber, and glass, the proposed method enables design transformations of the basic sound by allowing modification of mode gains that characterize natural sound for the material. In real-time virtual environment, it also provides simulation of modified sound according to the change of impact situation's perceptual properties such as colliding objects' size, hardness, contacting area, and speed. The test results on cognition experiment for discriminating objects' materials and impact situation by sound showed the feasibility of proposed auditory interaction design method.

The education effect of environmental impact cognitive instruction on high school students was investigated. Environmental values of students could be classified into egocentric, social-altruistic and biospheric values like those of Schultz’s three kinds of categories. The value distribution of students consists 44.7% of egocentric and biospheric value groups and 12.5% of social-altruistic value group, respectively. The environmental function such as knowledge and skill did not show remarkable differences between value groups. The environmental value only affected the attitude function. The biospheric value group had the higher attitude function than other value groups. The environmental impact cognitive instruction enhanced the environmental functions irrespective of the value group or instruction type. However, significant variables were different according to environmental functions. Environmental functions such as knowledge and skill were influenced by the instruction itself. The attitude function was dependent on instruction itself, value type and instruction type. The optimum application of the environmental impact cognitive instruction can be efficiently achieved through class division into egocentric value group and biospheric value group. Alternatively, the proper combination of instruction methods focused biospheric and egocentric impacts in a class can be recommended.

Amazon Go is a cashierless convenience store concept, which is seen as a disruption in the grocery retail segment. Although Amazon Go has the ability to disrupt the retail segment, there are speculations on how Amazon Go will be perceived by users. Existing studies have not utilized user-generated content to understand the factors that affect customer behaviour in case of Amazon Go. Additionally, in case of phygital retail, studies have not attempted at understanding the effect of emotions and gratifications on user behaviour. To address the gap of exploring user perspectives based on their experience, we have examined the impact of gratifications and emotions on the acceptance of phygital retail using user-generated-content. A mixed-method approach has been utilized using only user-generated content. Utilizing topic-modelling based content analysis and emotion analysis on 30 articles related to Amazon Go, we found themes like, convenience, technology, experience, personalization, enjoyment and emotions like, bad, good, annoyance, success. In the empirical analysis, we have utilized 522 reviews about Amazon Go from the cognition and emotion theory stance, and found that hedonic gratifications have a positive impact on challenge emotions. We also found a significant impact of emotions on customer's favourite behaviour.

Cognitive dysfunction is relatively less considered a complication of hypertension. However, there is sufficient evidence to show that high blood pressure in middle age increases the risk of cognitive decline and dementia in old age. The greatest impact on cognitive function in those with hypertension is on executive or frontal lobe function, similar to the area most damaged in vascular dementia. Possible cognitive disorders associated with hypertension are vascular dementia, Alzheimer disease, and Lewy body dementia, listed in decreasing strength of association. The pathophysiology of cognitive dysfunction in individuals with hypertension includes brain atrophy, microinfarcts, microbleeds, neuronal loss, white matter lesions, network disruption, neurovascular unit damage, reduced cerebral blood flow, blood-brain barrier damage, enlarged perivascular damage, and proteinopathy. Antihypertensive drugs may reduce the risk of cognitive decline and dementia. Given the high prevalence of dementia and its impact on quality of life, treatment of hypertension to reduce cognitive decline may be a clinically relevant intervention.
