For a long time, mathematics education institutions such as NCTM(National Council of Teachers of Mathematics) have emphasized the essential role of writing, and recent surveys by the Ministry of Education report a decline in foundational academic skills in the post-COVID19 period. The purpose of this study is to redefine the significance of mathematics writing in mathematics education, focusing on competencies highlighted in the field, particularly in the areas of problem-solving, communication, and reasoning. The research findings indicate that writing in problem-solving enhances cognitive organization, fostering the ability to grasp concepts and methods. Writing in communication builds confidence through the meta-cognitive process, and writing in inference allows self-awareness of step-by-step identification of areas lacking understanding. Particularly in the future society where artificial intelligence(AI) is utilized, changes in the learning environment necessitate research for the establishment of authenticity judgment through writing and the cultivation of a proper writing culture.

The present study investigated the impact of users' perceived benefits on their happiness and loyalty towards the university's online class system. Furthermore, the notion of loyalty was delineated into cognitive, emotional, intentional, and behavioral loyalty, and a systematic analysis was conducted to assess their respective impacts. The analysis was conducted using survey data obtained from a sample of 298 college students who possessed prior experience with the university's online class system. The analysis of the survey revealed that the satisfaction with the online class system was positively influenced by perceived practical benefits and symbolic benefits. However, it was found that emotional benefits did not have a statistically significant impact on satisfaction. Furthermore, it has been demonstrated that cognitive loyalty exerts a substantial beneficial impact on emotional loyalty, as well as a sequential and considerable positive influence on active and behavioral commitment inside the online class system established through perceived benefits. This study holds significance as it conducted an empirical analysis on the impact of users' perceived benefits of the university's online class system on their satisfaction levels, as well as its influence on the four-stage development process of loyalty.

This paper analyzes six different ways of articulating the relationship between art and politics. It calls attention to the differences that lurk behind the seemingly simple phrase-everywhere in vogue today-the "politics of aesthetics." Five of these models are drawn from contemporary discussions regarding the politics of art. The last model is the attempt to develop an account of the politics of aesthetics that is faithful to the difficult and ambiguous dimensions of the aesthetic experience that were hinted at by the texts of classical philosophical aesthetics. Most notably, this paper is concerned with the idea that the aesthetic experience can be understood as a form of disinterested contemplation-one that is not reducible to cognitive or moral considerations-and with some of the consequences that this entails. It explores some of the political significance that can be attributed to this idea of disinterested contemplation, arguing that the aesthetic should be understood as a withdrawal from the world's pre-established meanings. Unlike some of the other thinkers discussed in this paper, this author doubts that a single, uniform meaning can be ascribed to the aesthetic experience. I thus argue that we need to approach the aesthetic through the networks of textual significance that have been built up around it. Throughout this paper, I attempt to explain how the efforts to link art and aesthetics to politics simultaneously give rise to ideas about the nature of the human community. In looking at the sixth and final model, what I have called the "anarchical politics of aesthetic ambiguity," I argue that the aesthetic tradition offers a rather unique way of understanding the relationship between the individual and the community. Here, we see that the aesthetic is prone to a number of paradoxes, central among them the one that makes art the bearer of a solipsistic pleasure in which we nevertheless discover our capacity for genuinely communicating with others, outside of cliches and banalities.

Background: This study aimed to analyze correlations between depression, cognitive function, oral health state, ability to perform activities of daily living, oral dryness symptoms, and oral health-related quality of life, and determine factors influencing the latter. Methods: This was a cross-sectional study based on questionnaires completed by 260 participants with suspected dementia, residing in South Korea. Psychiatrists, psychiatric nurses, and dental hygienists visited clinics in the participating regions for examination and questionnaire administration. General characteristics, the geriatric depression scale, ability to perform activities of daily living, cognitive function, oral health state, and oral health-related quality of life were analyzed. Independent t-tests, one-way analysis of variance (ANOVA), correlation analysis and multiple regression analysis were conducted, identifying factors affecting oral health-related quality of life. Data analysis was performed using SPSS ver. 20.0 (IBM Corp., USA), and the significance was set at p<0.05. Results: Approximately 65.0% of participants were female, 63.5% were in their 70s, and 90.0% had health insurance. About 21.5%, 42.0%, and 36.5% were normal, slightly impaired, and had dementia, respectively. High cognitive impairment was associated with poor oral health. Sex, education levels, marital status, and living arrangements influenced oral health-related quality of life. According to the regression analysis, geriatric depression and oral dryness affected the Geriatric Oral Health Assessment Index scores. Conclusion: In conclusion, oral dryness and depression levels among elders influenced oral health-related quality of life. The results showed that to enhance elders' oral health-related quality of life, it is essential to not only improve their oral health state, but also relieve oral health problems, especially oral dryness, and take into consideration their psychological aspects.

The need for radio spectrum is recently considered as a huge hurdle towards the rapid development of wireless networks. Large parts of the spectrum are allocated to licensed radio services in proprietary way. However, enormous success of the wireless services and technologies in the unlicensed bands has brought new ideas and innovations. In recent years cognitive radio has gained much attention for solving the spectrum scarcity problem. It changes the way spectrum is regulated so that more efficient spectrum utilization is possible. Multi-hop relay technology on the other hand has intensively been studied in the area of ad hoc and peer-to-peer networks. But in cellular network, only recently the integration of multi-hop capability is considered to enhance the performance significantly. Multi-hop relaying can extend the coverage of the cell to provide high data rate service to a greater distance and in the shadowed regions. Very few papers still exist that combine these methods to maximize the spectrum utilization. Thus we propose a network architecture combining these two technologies in a way to maximize the system throughput. We present the throughput capacity equations for the proposed system model considering various system parameters like utilization factor by the primary users and primary users' transmission radius and through extensive numerical simulations we analyze the significance of work.

The purpose of the present study was to validate the Need for Closure Scale-Short Form (NFCS-SF), which measures the need for cognitive closure. Participants completed questionnaires regarding need for cognitive closure, intolerance of uncertainty, depression, and anxiety. Of the 536 data collected between May and July 2017, data from a total of 495 participants were analyzed using SPSS 20.0 and M-Plus. The results of the study are as follows. First, a 15-item selection comprised three items from each facet scale via exploratory factor analysis. Second, the NFCS-SF demonstrated good internal consistency (Study 1, Cronbach's α=.85; Study 2, Cronbach's α=.84). Third, the results of the confirmatory factor analyses supported a 5-factor model (χ2(80)=178.34, p<.001; CFI=.87, TLI=.83, RMSEA=.07, SRMR=.08). Fourth, the NFCS-SF showed significant correlation with the measures of intolerance of uncertainty (r=.58, p<.01), depression (r=.16, p<.05), and anxiety (state anxiety, r=.31, p<.01; trait anxiety, r=.29, as well as the NFCS (r=.86, p<.01). Based on these findings, significance and limitations of the results as well as suggestions for further study are discussed.

Melody is defined as adding spatial dimension to the rhythm which is temporal concept. Being able to understand melodic pattern and to reproduce the pattern also requires cognitive skills. Since 1980, there has been much research on the relationship between academic skills and music cognitive skills, and how to transfer the skills learned in music work to the academic learning. The study purported to examine various research outcomes dealing with the correlational and causal relationships between musical and academic skills. The two dominating theories explaining the connection between two skills ares are "neural theory" and "near transfer theory." The theories focus mainly on the transference of spatial and temporal reasoning which are reinforced in the musical learning. The study reviewed the existing meta-analysis studies, which provided evidence for positive correlation between academic and musical skills, and significance of musical learning in academic skills. The study further examined specific skills area that musical learning is correlated, such as mathematics and reading. The research stated that among many mathematical concepts, proportional topics have the strongest correlation with musical skills. Also with reading, temporal processing also has strong relationship with auditory skills and motor skills, and further affect language and literacy ability. The study suggest that skills learned in the musical work can be transferred to other areas of learning and structured music activities may be every efficient for children for facilitating academic concepts.

To analyze in detail the cognitive factors in the sense of place in Korea traditional temples and their occurrence and significance, the questionaring was conducted about the actual condition of visitor's using of and preference for Pulkuksa Temple as an object of the investigation. The result from the analysis of the visitors' sense of respective factors forming the image of the temple is as follows: 1. While the male visitors for outnumbered the female, the female visitors are more satisfied with the senses of the temple than male. The younger visitors are larger in number while the older visitors have the more satisfaction. It took the largest number of the visitors at least three hours to come to the temple. The most numerous are the visitors who came to the temple. The most numerous are the visitors who came to the temple by their own cars. The visitors are coming not only from the Kyunsang Provinces but from all over the country and they made a family trip to the temple. 2. 86 people among the questionees replied that the Tower stands best for Pulkuksa temple. The second largest number of the questionees replied that the main sanctuary does. The third largest number of the questionees replied that the natural environment does. 3. The visitors who came to the temple for sightseeing showed their highest preferences for each of the main sanctuary and the tower. The buddhist visitors also showed the same tendency as non Buddhist ones in their preference. 4. On the whole, the space factors such as buildings and scenes which represent Pulkuksa Temple are the towers such as Sukka Tower and Tabo Tower, the sanctuary buildings such as main sanctuary, the natural scenery such as Toham Mountain, and the steps such as Chungwun-Kyo and Paekwun-Kyo. 5. The potential factors to explain the structural characteristics of the scenery in Pulkuksa Temple are revealed to be a factor of overall valuation, of orderliness, of individuality and of comfortableness, through hypothetical. T.V was 54.1% and the orderliness of Sukkatap was highly evaluated in factor score analysis.
