Abstract
Purpose
Equisetum arvense L. (Equisetum) is a weed that is very difficult to remove because of its deep roots. The purpose of this paper is to examine the dyeability and antioxidant activity of Equisetum extracted from hot water.
Design/methodology/approach
Dry Equisetum was extracted at 100°C for 2 h, and its dyeability according to time, temperature and repetition cycle, and the mordant effect by skim milk powder were confirmed. The color change according to the K/S, fastness to rubbing, light, sweat and washing, UV protection rate and antioxidant activity were evaluated.
Findings
UV‒Vis spectroscopy showed that the Equisetum extract contained a flavonoid compound. The addition of Equisetum to artificial silk produced the greatest color difference when dyed at 60°C for 1 h, and the K/S value increased slightly after the pre-mordant treatment. In the fastness test, light and washing had no significant effect, but the fastness to rubbing was very good at Grades 4 and 5, and there was also a considerable improvement in the UV protection rate. The antioxidant activity of the extract was confirmed by an analysis of the radical scavenging ability through the DPPH (1,1-diphenyl 2-picryl-hydrazyl) and ABTS ([2,2’- azino-bis (3-ethylbenzothialzoline-6-sulfonic acid) diammonium salt]) tests.
Originality/value
These results revealed a new natural antioxidant-containing dyestuff, weed grass, which is easy to obtain, easy to use as a dyeing material and has excellent antioxidant activity in an extracted dye solution and dyeing fabric.

Abstract
Purpose
The purpose of this paper is to investigate the structural relationships among transformational leadership, affective organizational commitment and job performance, as well as the mediating effect of employee engagement on their relationships.
Design/methodology/approach
To examine the structural relationships among the research variables, structural equation modeling analysis and bootstrap estimates were performed using the data of 600 full-time employees working in Korean private organizations.
Findings
The results of the data analysis suggest that transformational leadership had a significant impact on employee affective organizational commitment and job performance through employee engagement as a mediator. Specifically, employee engagement partially mediated the mechanism in which transformational leadership affects employee affective organizational commitment, whereas there existed a full mediation of the association between transformational leadership and job performance.
Practical implications
The study finding suggested that transformational leadership was the key catalyst in both encouraging affective organizational commitment and task performance of employees throughout the mediator, employee engagement. Thus, organizations need to create a safe and positive environment that promotes employee engagement and should offer interventions for leaders to build skill sets of transformational leadership.
Originality/value
Because previous studies had explored the impacts of transformational leadership on employee positive attitude and job performance separately, there is little known about how these three constructs correlate. By investigating the impacts of transformational leadership on attitude and performance simultaneously in this study, this study expanded to the extant literature by providing better understanding of transformational leadership. Moreover, given that articles on transformational leadership have been limited in the HRD literature, findings of this study can offer trustworthy information for HRD practice and encourage HRD scholars to explore transformational leadership-related research.

Abstract
Purpose
The purpose of this qualitative study is to explore how highly educated women respond to career chance events in a Korean context where traditional cultural values and male-dominated organizational culture coexist.
Design/methodology/approach
The authors conducted 50 semi-structured interviews with highly educated women operationalized as women with doctoral degrees in and out of Korea. The authors used a collaborative research process with a team of ten Korean-born researchers who have built consensus on research themes through discussions on the collection and analysis of a large data set, thus reducing the researcher bias issue inherent in qualitative research.
Findings
In an analysis of the interview data collected, the authors report on three themes: before obtaining a doctoral degree, during and after their doctoral study and responses (coping strategies) to chance events in their careers. Highly educated women’s pursuing a doctoral degree was a way to maintain work–life balance in Korea where women are expected to take a primary caregiver role. After obtaining a doctoral degree, participants struggled with limited job opportunities in the male-dominated higher education. Women’s unplanned and unexpected chance events are intertwined with the male-dominated culture in Korea, and career interruptions as such a chance event, whether voluntary or involuntary, happened largely due to family reasons. In this context, highly educated women responded to chance events largely at individual and family levels and articulated the need for support at organizational and government levels.
Research limitations/implications
The study findings confirm the literature that women’s careers are limited by traditional family roles in non-Western countries where strong patriarchal culture is prevalent. Particularly, women’s career interruptions surfaced as a critical chance event that either disrupts or delays their careers largely because of family issues. Future research is called for to identify both individual and contextual factors that influence women’s decisions on voluntary and involuntary career interruptions as their responses to chance events.
Practical implications
Based on highly educated women’s coping strategies largely at individual and family levels, we suggest national human resource development policies put in place not to lose out on the opportunity to develop highly educated women with doctoral degrees as a quality workforce for a nation’s sustainable economic growth. Additionally, organizations need to be aligned with the government policies and programs for the provision of developmental programs for women in the workplace, beginning with highly educated women’s career planning, while creating organizational culture to promote gender equality as a long-term goal.
Originality/value
The participants’ voluntary career breaks helped them care for their children, be involved in their children’s education, reflect on work–life balance after having long hours of work for many years and move forward with personal satisfaction. Voluntary career breaks can be understood as highly educated women’s unique way of responding to chance events.

Abstract
Purpose
When facilitating transmission of health information from government officials to the public, social media employs algorithms that selectively expose users to specific perspectives, even for accurate health-related information from official sources. The purpose of this study was to explore impact of algorithm-driven comments characterized by different emotional tones (i.e. positive vs. negative vs. mixed) on users’ perceptions of credibility of corrective information to examine misinformation about flu vaccines aimed at young adults. Additionally, this study explored how prior misinformation credibility acted as an intervening variable in shaping the impact of algorithmically generated comments with diverse emotional tones on credibility of corrective information, with algorithm credibility serving as a mediator.
Design/methodology/approach
An online experiment was conducted with 275 participants recruited from Amazon Mechanical Turk (MTurk). Young adults from the USA aged between 18 and 35 years who were also users of Instagram were eligible for participating in this study as this study utilized Instagram platform for stimuli.
Findings
Results highlighted a diminished impact of algorithm-generated negative comments on perceived credibility of corrective information. Additionally, individuals with high misinformation credibility demonstrated a stronger tendency to trust algorithms featuring negative comments, underscoring the significant impact of algorithm-driven negativity in shaping trust dynamics for this group. Notably, credibility of the algorithm among individuals with high misinformation credibility did not translate into increased credibility for corrective information. This suggests that strategically designing algorithms to emphasize supportive or diverse opinions can be an effective approach to alleviate potential negative consequences associated with accurate information.
Originality/value
This research signifies the initial effort to disentangle the dynamics between negativity bias and cue routes within the algorithmic framework, shaping individuals’ perceptions of credibility of accurate health-related information contingent on accompanying comments. In the context of social media platforms that embrace diverse opinions, it emphasizes the critical necessity for tailored algorithmic strategies to effectively deliver accurate information.

Abstract
Purpose
The purpose of this study is to assess the possibility of introducing a restaurant-menu curation (RMC) chatbot service to help consumers quickly and effectively decide on their restaurant or menu choices. To this end, it measures the characteristics of consumer chatbot experiences and analyzes their impact on future acceptance intentions through their attitudes toward the RMC chatbot service.
Design/methodology/approach
This study consists of three parts: developing a RMC chatbot prototype, testing the chatbot prototype and a customer survey based on experience. A convenience sample method was used to collect data from 368 adults who tried the RMC chatbot service before answering a self-administered questionnaire. Partial least squares structural equation modeling (PLS-SEM) was used to test the proposed structural model.
Findings
The results showed that all experience characteristics, except usable facets, had a significant positive impact on attitudes toward the chatbot. Three experience characteristics, “usable,” “usefulness” and “valuable,” revealed a significant positive effect on utilization intention. Attitudes toward chatbot services also significantly affected utilization intention.
Research limitations/implications
The results of this study can offer practical and academic implications for establishing curation services in the restaurant industry that can increase customer acceptance and utilization intentions. Follow-up studies are required to explore and verify the various personal and psychological factors related to the intention to accept RMC chatbot services.
Originality/value
This study is meaningful because it makes it possible to evaluate the introduction of curation chatbot services in the restaurant sector, by developing and testing the dining-out curation service protocol to help customers’ smart choices in the information technology environment.

Abstract
Purpose
This study aims to explore Twitter use by Korea's central government by classifying the government's Twitter-based networking strategies into government-to-citizen (G2C) and government-to-government (G2G) strategies.
Design/methodology/approach
The study investigates the nature of social media interactions and networking strategies in the Korean government by extracting tweets, follower/following relationships, and hyperlinks for 32 ministries. Network patterns and networking strategies are reviewed through descriptive statistical analysis and social network analysis to map the government's Twitter activity.
Findings
The results indicate that the government's direct networking strategy targeting citizens does not necessarily motivate their participation in the government's social media activities but that it plays an instrumental role in reinforcing G2G relationships.
Originality/value
This study investigates the social media use patterns (e.g. network properties and co-link analyses) and strategies (e.g. the reciprocity of relationships and content-push strategies) in the context of G2C and G2G relationships in Korea's public sector.

Abstract
Purpose
The purpose of this research is to conduct an exploratory study to discover if presenting consumers with a certain content type (i.e. product-focused content with informational appeal, institution-focused content with emotional appeal, experience-focused content with emotional appeal,) and blog type (i.e. a corporate, sponsored or a personal blog) persuade consumers to form perceptions of credibility and similarity toward the fashion brand, which leads them to further engage with the brand through Electronic Word of Mouth (eWOM).
Design/methodology/approach
This study employs a 3(content type: product-focused, institution-focused, experience-focused) x 3(blog type: corporate, sponsored and personal) between-subjects design. Mock fashion blogs and content were developed in order to provide a realistic blogging experience for the participants. With 511 usable data collected, ANOVA was employed to test the relationships.
Findings
Findings reveal that content type, specifically product-focused content and experiential content, is an important consideration for illustrating similarities between the brand and consumers compared to institutional content. Product-focused content is found to be effective in encouraging consumer eWOM for the brand as well. Further, the interaction effect of blog type and content type was significant in establishing brand credibility. However, blog type did not influence any of the dependent variable.
Originality/value
This study brings meaningful suggestions to fashion brands on effective blog campaign, which eventually provide insights on how brands can influence female consumers to shape positive evaluation toward the brand.

Abstract
Purpose
The purpose of this study was to identify existing users' acceptance of the multidimensional health and fitness features of wrist-worn wearable devices (WWDs) required for each stage of physical activity (i.e. before, during and after) and examine the relationship between its acceptance (i.e. knowledge acquisition, perceived usefulness and perceived ease of use) and the actual use of its health and fitness attributes.
Design/methodology/approach
Both qualitative and quantitative approaches were taken to analyze the relationships. A focus group interview was conducted (N = 9) to design the research model, including the operationalized definition of the study constructs. A questionnaire survey was conducted with respondents in South Korea (N = 480). Partial least squares structural equation modeling via Smart PLS 3.0 was employed to test the hypotheses.
Findings
When users learned to use fitness functions and perceived them as useful for physical activity without causing any difficulty, they tended to use those functions more, which provided enhanced health benefits in the digitalized interactive environment of WWDs.
Originality/value
This research is one of the first to examine the relationship between the perceived user value of WWDs and their actual usage within a digitalized and interactive environment. The results are expected to offer theoretical insights into how well users accept the health and fitness components of WWDs. Practically, it will build awareness of what makes users adopt and use WWDs, helping practitioners design better health promotions and campaigns associated with WWDs.

Abstract
Purpose
The purpose of this study is to investigate (1) how female blog users' perceived benefits (i.e. perceived usefulness, perceived enjoyment, community identification and perceived norm of reciprocity) influence their perceived social capital on fashion blogs, (2) the influence of structural social capital and cognitive social capital on users' relational social capital and (3) the influence of relational social capital on blog loyalty.
Design/methodology/approach
Structural equation modeling was performed using 530 useable data collected through an online survey.
Findings
The result indicated that perceived usefulness and the norm of reciprocity led to the development of cognitive social capital, while community identification and the norm of reciprocity led to the development of structural social capital. Cognitive and structural social capital both led to the development relational social capital, which in turn influenced blog loyalty.
Originality/value
This study provides insights for a fashion brand marketing strategy that uses fashion blogs to target relevant consumers. It helps firms to understand the factors that lead people to embed their resources in a blog and to learn how the different perceived benefits impact blog users' contributions to the community.
