Objectives: The purpose of this study is to provide basic data for elucidating the clinical experiences of nursing assistants working at dental clinics and for establishing the bases necessary for building a safe working environment for the staff at dental clinics. Methods: From March 28 to August 20, 2022, the study conducted in-depth interviews with nursing assistants working with dental hygienists in dental clinics. The collected data were analyzed using the phenomenological method. Results: The study analyzed the meanings associated with the dental clinical assistance work experiences of nursing assistants in dental clinics. A total of 98 semantic words and 9 sub-categories were extracted, which were ultimately categorized into 4 central meanings: 'imperfect reality', 'work without boundaries', 'putting oneself in someone else's shoes', and 'symbiosis'. Conclusions: The nursing assistants were exposed to an environment where they needed to perform delegated treatment procedures even when they lacked dental work competency. They recognized their gaps in learning and the necessity for designated roles as clinical assistants. Thus, it is necessary to review the allocation and expansion of the work roles of dental practitioners based on the practical and rational realities in dental practice.

This paper aims to examine the effect that cultural marketing influences on visit motivation and customer responses. We found that cultural marketing promotion activities by Benares, Indian restaurant had a positive effect on motivation to visit the store. Also research showed that the cultural direction and positioning marketing activities of Benares' cultural marketing had a statistically significant positive effect on all items of customer responses, that is service, atmosphere, brand but cultural promotion and cultural support marketing activities had a positive effect only on brand, except service, atmosphere. In addition, research showed that while all items of customer responses had a positive effect on revisit intention. In other words, it was proven that cultural marketing promotion activities by the Third World restaurant influence on visit motivation and customer responses and it provides practical implications to business marketers that foodservice companies' marketing associated with cultural marketing activities can be efficient marketing strategies that influence on revisit intention.

The aim of this study was to investigate changes in the weight of Zophobas morio larvae and mass of polystyrene foam when the larvae were fed polystyrene for 27 days. Fourier-transform infrared (FTIR) spectrometry was used to determine whether the polystyrene was broken down by the larvae. Forty Z. morio larvae (four replicates with 10 larvae per replicate) were reared in a chamber under controlled conditions with polystyrene foam blocks as their sole diet. The weight of the Z. morio larvae and mass of the polystyrene foam decreased as a function of time. The average weight of the larvae and mass of the polystyrene foam blocks decreased by 16.3 and 6.5%, respectively, over the 27-day period. The FTIR spectrum of Z. morio larvae fed with polystyrene foam did not reveal the unique peaks associated with polystyrene. In conclusion, this study suggests the possibility of using Z. morio larvae as a management technology for degrading waste plastics without a negative environmental effect. Key words : FTIR spectra, plastic biodegradation, polystyrene foam, Zophobas morio larvae.

Purpose: This study analyzed research trends in infant and toddler rearing behavior among family caregivers over a 10-year period (2010-2021). Methods: Text network analysis and topic modeling were employed on data collected from relevant papers, following the extraction and refinement of semantic morphemes. A semantic-centered network was constructed by extracting words from 2,613 English-language abstracts. Data analysis was performed using NetMiner 4.5.0. Results: Frequency analysis, degree centrality, and eigenvector centrality all revealed the terms ''scale," ''program," and ''education" among the top 10 keywords associated with infant and toddler rearing behaviors among family caregivers. The keywords extracted from the analysis were divided into two clusters through cohesion analysis. Additionally, they were classified into two topic groups using topic modeling: "program and evaluation" (64.37%) and "caregivers' role and competency in child development" (35.63%). Conclusion: The roles and competencies of family caregivers are essential for the development of infants and toddlers. Intervention programs and evaluations are necessary to improve rearing behaviors. Future research should determine the role of nurses in supporting family caregivers. Additionally, it should facilitate the development of nursing strategies and intervention programs to promote positive rearing practices.

Despite the significant increase of Korean contractors in the international construction market, many SMCCs (Small & Medium Construction Companies) have suffered in the global financial crisis, and some of them have been kicked out of the international market after experiencing huge losses on projects. SMCCs face obstacles in the international market, such as an insufficient ability to gather information and inappropriate management of associated risks, which lead to difficulties in establishing effective business strategies. In other words, making immature decisions without an effective business strategy may cause not only the failure of one project but also the bankruptcy of the SMCC. To overcome this, the research presented herein aims to propose a decision support system for SMCCs, which would screen projects and make a go/no-go decision at the early stages of international projects. The proposed system comprises a double axis: (1) a profit prediction model, which evaluates 10 project properties using an objective methodology based on a historical project performance database and roughly suggests expected profit rate, and (2) a feasibility assessment model, which evaluates 17 project environment factors in a subjective and quantitative methodology based on experience and supervision. Finally, a web-based system is established to enhance the practical usability, which is expected to be a good reference for inexperienced SMCCs to make proper decisions and establish effective business strategies.

Purpose: This is a study to confirm the mediating effect of positive psychological capital in the relationship between the self-determination and grit of nursing students. Methods: The subjects of the study were 122 university nursing department students in their junior and senior years. The data were collected from December 1 to 23, 2022. The collected data were analyzed by descriptive statistics, an independent t-test, Mann-Whitney U-test, Pearson's correlation, and a hierarchical multiple regression analysis using IBM SPSS statistics version 26.0. Results: A statistically significant correlation was observed between self-determination, positive psychological capital and grit (p<.001). The positive psychological capital had full mediation effects on the relationship between self-determination and grit. In other words, the higher levels of positive psychological capital were associated with better levels of grit among nursing students. Conclusion: The study showed that positive psychological capital and self-determination have important effects on grit. To enhance the grit of nursing students, it is essential to implement educational programs aimed at improving self-determination and positive psychological capital.

Objective: The purpose of this study was to examine the effect of communication and cooperation between teachers and parents on infant care. Specifically, this study explored the direct effect of teacher-parent partnership on teacher-infant interactions and the indirect effect through teacher sensitivity. Methods: The participants of this study were 216 teachers in charge of infant classes at child care centers located in Gyeonggi-do. They responded to questionnaires on teacher-parent partnership, their sensitivity, and teacher-infant interactions. Data were analyzed using structural equation modeling. Results: First, teacher-parent partnership did not have a direct impact on teacher-infant interactions. Second, teacher-parent partnership indirectly influenced teacher-infant interactions through teacher sensitivity. In other words, a high level of teacher-parent partnership was associated with a high level of sensitivity, subsequently resulting in the provision of high-quality interactions for infants. Conclusion/Implications: This study confirmed the role of teacher sensitivity as a mechanism to explain how teacher-parent partnership is linked to teacher-child interactions. The results emphasize the importance of communication and cooperation between teachers and parents in enhancing teachers' sensitivity and, ultimately, providing high-quality child care to infants.

Online product reviews are a vital source for companies in that they contain consumers' opinions of products. The earlier methods of opinion mining, which involve drawing semantic information from text, have been mostly applied in one dimension. This is not sufficient in itself to elicit reviewers' comprehensive views on products. In this paper, we propose a novel approach in opinion mining by projecting online consumers' reviews in a multidimensional framework to improve review interpretation of products. First of all, we set up a new framework consisting of six dimensions based on a marketing management theory. To calculate the distances of review sentences and each dimension, we embed words in reviews utilizing Google's pre-trained word2vector model. We classified each sentence of the reviews into the respective dimensions of our new framework. After the classification, we measured the sentiment degrees for each sentence. The results were plotted using a radar graph in which the axes are the dimensions of the framework. We tested the strategy on Amazon product reviews of the iPhone and Galaxy smartphone series with a total of around 21,000 sentences. The results showed that the radar graphs visually reflected several issues associated with the products. The proposed method is not for specific product categories. It can be generally applied for opinion mining on reviews of any product category.

ChatGPT, a leading example of generative AI, is expanding the use of its LLM (Large Language Model) from traditional academic fields such as literature and creative writing to practical areas like management, tourism, and media. This study was conducted with active seniors to analyze their perceptions of travel and tourism, identifying key areas of interest and specific details. ChatGPT was utilized as an analytical tool in major areas of the study, providing suggestions for key findings.The research findings are as follows: First, terms closely associated with active senior travel include retirement, together, service, consumption, leisure, health, life, hobby, culture, generation, platform, wellness, and program. Second, centrality analysis showed that words like service, leisure, and together had high degrees of centrality and closeness centrality, while terms such as health, domestic, culture, activity, program, and life had high closeness centrality. Third, based on the CONCOR analysis with suggestions from ChatGPT, two clusters were identified: 'Retirement and Lifestyle' and 'Senior Services and Platforms'. Based on the research findings, practical implications for active senior travel were identified, along with academic implications for the field of tourism studies.

Amid the rapid growth in use of portal news, this study examined whether portal news would substitute traditional news media, in particular newspapers and television news. To answer the research question, this study attempted to investigate how the decrease in use of traditional news media was associated with online news use, reliance on, and motivations for portal news. First, this study found that there was a negative and significant relationship between the Internet use and television news viewing, suggesting that those who are more likely to use the Internet are less likely to watch television news programs. Also, portal news was negatively associated with time spent with newspaper reading, while it was not related to television news viewing. Second, this study found that convenience/information-seeking needs appeared as the major motivations for using portal news, which were negatively and significantly associated with the decreased time spent with watching television news programs. In other words, those who used portal news for convenience/information-seeking needs are less likely to watch television news programs, which may indicate that portal news could be a substitute for television news in terms of convenience/information-seeking motivations. In addition, the result of this study showed that there was a complementary relationship between portal news and newspapers in terms of surveillance needs. Those findings could be explained by the concept of "functional similarity" in the process of media substitution. Based on the findings, implications of this study were discussed.
