This study analyzes the effects of food delivery selection attributes on satisfaction and intention to continue using food delivery services among ‘the Young-Old’(60-74 years old) living in Daejeon Metropolitan City who use the Senior Center, Gyeongnodang. Considering that the research subjects are elderly, the survey was conducted using an interview technique. The survey period was approximately three months, from May 1, 2025, and a total of 235 copies were collected and used for research. Overall, ‘the Young-Old’ prioritize price over anything else when choosing delivery services, and they primarily use the services to enjoy delicious food or to simply solve a meal. Furthermore, the economic feasibility, convenience, and hygiene of delivery services are key factors in driving satisfaction when using delivery services, and this satisfaction can lead to continued intentions to use delivery services. Therefore, food delivery companies should pay special attention to providing detailed nutritional information and hygiene management to increase the satisfaction of ‘the Young-Old’ customer and encourage their continued use of delivery services, as they may prioritize health and safety over taste or price. Furthermore, food delivery companies need to develop easy-to-use, senior-friendly delivery app interfaces or enhance phone ordering services to improve accessibility of delivery. The government and local governments can leverage these research findings to introduce food delivery vouchers or discount policies targeting the seniors. This can not only help seniors meet their meal needs but also generate new demand in the food delivery market. This research sets a starting point for a study that approaches the commercial phenomenon of food delivery from a gerontological and social welfare perspective, targeting ‘the Young-Old’ generation as active consumers. In other words, this research will serve as a valuable foundation for understanding the changing lifestyles of older adults due to societal changes.

The findings underscore the non-linear and asymmetric nature of customer responses to various service attributes, highlighting the significant influence of economic factors and the pandemic on dining expectations and experiences. This research deepens our understanding of the factors shaping customer satisfaction dynamics, particularly in the context of the evolving post-pandemic restaurant industry.

Wheat (Triticum aestivum L.), a significant cereal crop from the Gramineae family, serves as a vital source of protein, essential minerals, B-group vitamins, and dietary fiber. However, its productivity is often hindered by issues such as poor seed germination, which can adversely affect yield and crop quality. This study investigated the effects of different silicon concentrations and priming durations on wheat germination and seedling growth. Analysis of variance revealed that silicon treatment significantly influenced key parameters of germination and growth, including germination percentage (GP), germination index (GI), vigor index (VI), radicle length (RL), plumule length (PL), and seedling dry weight (SDW). Priming with silicon at a concentration of 1 mM resulted in notable improvements, increasing GP, GI, VI, RL, and PL by 10.6%, 65.5%, 29.4%, 18.6%, and 28.6%, respectively, after 6 hours of priming. Certain germination traits demonstrated strong positive correlations, particularly GP and GI (r = 0.96) and VI and RL (r = 0.94), after 4 hours of priming. These improvements in seed germination and seedling development may result from enhanced water uptake, stimulated cell division, and increased hydrolytic enzyme activity, which facilitate the mobilization of seed reserves and accelerate the growth of embryonic tissues.

The objective of this study was to categorize consumers' food-related lifestyles into various types and discern the differences in consumer preferences for locally sourced ingredients in Home Meal Replacement (HMR) based on food-related lifestyles. The online survey was conducted from December, 2020, involving 474 adults who registered with Macro Mill Embrain. Statistical analyses, including frequency analysis, descriptive statistics, factor analysis, K-means cluster analysis, and one-way ANOVA were applied to the collected data. The findings revealed the ‘convenience-seeking group,’ the 'high interest in food-related lifestyle group,' and the ‘health and taste-seeking group.’ The ‘convenience-seeking group’ showed a high proportion of respondents (65%) didn’t check the origin, whereas the ’high interest in food-related lifestyle group’ (57.5%) and the ‘health and taste-seeking group’ (66.7) had higher proportions of respondents who checked the origin. Regarding the reasons for preferring locally sourced HMR, all three clusters emphasized safety, hygiene, and fresh ingredients as the most critical factors. This study represented the first exploration into consumer preferences for HMR using locally sourced ingredients, segmented by their food-related lifestyles. The findings provided valuable foundational information for the development of HMR using locally sourced ingredients and could be applied to decisions in the food industry and related policy-making.

This study aimed to identify consumer demands and propose improvement measures for restaurants by conducting an importance-satisfaction analysis of the attributes that influence dining consumers’ restaurant selection. The key findings are as follows: An analysis of consumer hygiene behavior revealed that participants were particularly vigilant about washing food ingredients, checking expiration dates, and maintaining personal hygiene before meals. Notably, women exhibited significantly higher hygiene behaviors than men in 9 out of 12 items. The importance analysis of restaurant selection attributes indicated that “food cleanliness” and “food taste” were prioritized, with women assigning higher importance to almost all attributes, particularly emphasizing restaurant cleanliness and food taste. The satisfaction analysis showed that “food taste” and “food cleanliness” were the most satisfying attributes, with significant gender differences observed in 4 out of 26 items. The importance-satisfaction analysis demonstrated that satisfaction levels were consistently lower than importance levels across all 26 attributes. The ISA analysis identified that items in the second quadrant, such as restroom cleanliness, reasonable price, and the provision of food safety information, were in the most urgent need of improvement. Overall, the study highlights that consumers place a high level of importance on hygiene and cleanliness in restaurants, reflecting a market with increasingly stringent hygiene standards.

This study aimed to understand the needs of consumers in the meal kit market and determine the impact of meal kit selection attributes according to the consumption behavior of single-person households on purchase decisions and satisfaction. A summary of the results of this study is as follows: First, the most frequent purchase frequency of meal kits was 2 to 3 times a month. The reason for purchase was that it was easy to consume, and the most common purpose of purchase was for consumption. Second, four factors, including health, convenience, taste, and economics, were derived as a result of a factor analysis of meal kit selection attributes. The difference in meal kit selection attributes according to age groups revealed that those in their 20s had high scores with respect to health and taste factors, and economic factors appeared statistically significant. Third, an analysis of the meal kit product selection attributes showed that health and taste factors had a positive influence on satisfaction. This can be said to reflect the tendency of single-person households to give weightage to healthy eating and to purchase products that can be consumed conveniently.

The purpose of this study is to analyze the characteristic of quality attributes of smart hotels by using a SERVQUAL-IPA model, focusing on Chinese, which has the most proactive approach for the adoption of smart hotel system. Toward this goal, six quality factors—tangibles, reliability, assurance, responsiveness, empathy, and playfulness—were extracted through factor analysis, and IPA was used to appraise the degree of importance and satisfaction for each quality attribute. As a result of the SERVQUAL-IPA model, quality attributes were categorized into four groups of 'keep up the good work,' 'possible overkill,' 'low priority,' and 'concentrate here.'. Furthermore, it was concluded that there is a need to focus on the following elements: ‘smart devices can assist customers in emergency situations’, ‘when the room control system identifies customer needs, the staff can provide prompt service’, ‘development and improvement of mobile applications that enable customers to control room amenities’, ‘regular maintenance for smart devices’, and ‘providing data-driven personalized recommendations through customer activity data analysis’.

This study aims to investigate how consumers perceive the attributes (ubiquity, continuity) of metaverse fashion brands in a virtual space. It also empirically verifies the impact on consumers’ perceived values (hedonic value, social value) and consumer behavioral intentions (intention to use the platform, intention to purchase virtual products). The results verified in this study are as follows: First, we confirmed that the metaverse attributes perceived by consumers in the virtual space of the fashion brand, ubiquity and daily extension, positively affect customers’ perceived hedonic and social values. Second, we found that consumers’ perceived hedonic and social values have a significant positive effect on their intention to use the platform. Finally, we found that consumers’ intention to use the platform had a significant positive effect on their intention to purchase virtual products. The results of this study will have academic significance by expanding the scope of research related to identifying metaverse attributes and values by identifying metaverse attributes and consumer values that perceived by consumers in fashion brands’ virtual spaces in the metaverse. This study suggests a direction and strategy for fashion brands to move forward in building virtual spaces on the metaverse platform. In this way, they can create perceived value for consumers that elicits positive consumer behavioral intentions.

Vertical takeoff and landing (VTOL) is a core feature of unmanned aerial vehicles (UAVs), which are commonly referred to as drones. In emerging smart logistics, drones are expected to play an increasingly important role as mobile platforms. Therefore, research on last-mile delivery using drones is on the rise. There is a growing trend toward providing drone delivery services, particularly among retailers that handle small and lightweight items. However, there is still a lack of research on a structural definition of the VTOL drone flight model for multi-point delivery service. This paper describes a VTOL drone flight route structure for a multi-drone delivery service using rotary-wing type VTOL drones. First, we briefly explore the factors to be considered when providing drone delivery services. Second, a VTOL drone flight route model is introduced using the idea of the nested graph. Based on the proposed model, we describe various time-related attributes for delivery services using drones and present corresponding calculation methods. Additionally, as an application of the drone route model and the time attributes, we comprehensively describe a simple example of the multi-drone delivery for first-come-first-served (FCFS) services.

In this study, based on previous research on personal broadcasting, we indirectly measured content quality, YouTuber attributes, user satisfaction, and behavioral intention, which are latent variables that cannot be directly measured, as measurement variables, and then measured theoretically between the latent variables. In order to analyze the causal relationship, we used a structural equation model to determine to what extent the content quality of the YouTube mukbang channel and the YouTuber's attributes influence behavioral intentions such as purchase, recommendation, and continued use according to viewers' satisfaction with use. We intend to analyze and verify the relationship between related variables. The research results are as follows. First, the value, relevance, timeliness, completeness, and data quantity of content quality were found to have no significant impact on user satisfaction. Second, the trustworthiness, expertise, attractiveness, and intimacy of YouTuber attributes were found to have a significant impact on user satisfaction, but the similarity of YouTuber attributes did not have a significant impact on usage. Third, user satisfaction was found to have a significant impact on behavioral intentions and purchase intentions. However, user satisfaction was not found to have a direct significant impact on recommendation intentions or continued usage intentions.

This study examines options to revitalize a B2B textile trading platform, exploring user satisfaction and perceptions of the importance of several website features. Between June 8 and June 21, 2023, fashion studies majors and domestic fashion brand product planners were asked to use the website of an open B2B textile platform for 30 minutes and then evaluate its features by responding to a survey. The final sample for analysis wad comprised of 150 questionnaires. To analyze the key textile website features, a paired t-test, Importance-Performance Analysis (IPA), and multiple regression analysis were utilized. The analysis classified the key textile website features related to user importance and satisfaction into the following categories: convenience, appearance, product information, and uniqueness. An analysis investigation of the differences in importance and satisfaction for each website evaluation attribute found significant differences in 12 attributes. The IPA analysis revealed that attributes such as product reliability, quality, a convenient search function, and convenient page movement are highly important to users and garner high user satisfaction; these findings demonstrate the importance of maintaining these elements. Images on the main screen, the latest trend information, and product prominence attributes also garner high importance ratings, but result in low user satisfaction, which signifies extensive revision is required. Finally, user evaluation of the convenience, appearance, and product information of the website was found to affect user recommendation intention.
