Purpose The purpose of this paper is to examine the moderating effect of uncertainty avoidance (UA) on the relationships among subjective knowledge, attitude toward Korean foods and dining out behavioral intentions (BI) of foreign residents in Korea. Design/methodology/approach A total of 247 foreign residents in Korea were participated through a street intercept survey at several locations in metropolitan areas of South Korea. Subsequently, the samples were divided into two groups (a low UA group and a high UA group) for multiple group analysis to examine the moderating role of UA. Findings The results of structural equation modeling showed that subjective knowledge and attitude toward Korean foods significantly influenced intention to visit Korean restaurants. Furthermore, multiple group analysis results showed that UA had a significant moderating effect as a cultural dimension on the relationships between subjective knowledge and BI, as well as between attitude and BI. Research limitations/implications This research has made the first attempt to account for UA in examining the relationships among subjective knowledge, attitude and BIs, especially for ambiguous situations where foreign residents who are new to the mainstream Korean food culture face challenges in visiting Korean restaurants. Practical implications The findings indicate that enhancing subjective knowledge about Korean foods should increase the probability of foreign residents visiting Korean restaurants, so restaurant marketers should consider subjective knowledge as they work to encourage foreign residents to try Korean foods. Furthermore, planning strategies for marketing to foreign residents should consider level of UA among foreigners. Originality/value This study first illustrates the value of considering the cultural trait of UA in examining dining out behavior at ethnic restaurants. The UA trait sheds light on how subjective knowledge helps predict attitude and dining out BI at ethnic restaurants.

Cudrania tricuspidata is a traditional medicinal herb in East Asia. The compounds of plants vary depending on environmental factors, such as soil, temperature, drainage, and so on. However, few to no studies have been done on the correlation among environment, growth, and compounds in C. tricuspidata. Thus, we aimed to investigate their relationship. Samples of C. tricuspidata fruit and cultivation soil were collected from 28 cultivation sites in October 2021. Six growth characteristics, eleven soil physicochemical properties, seven meteorological data points, and three active compounds were investigated in this study. We developed and validated an optimized method for quantifying active compounds using UPLC and performed correlation analysis of the environment, growth characteristics, and active compounds. The UPLC-UV method for determining active compounds was validated by measuring the linearity, LOD, LOQ, precision, and accuracy using UPLC. The LOD and LOQ were 0.01–0.03 µg/mL and 0.04–0.09 µg/mL, respectively. The precision was acceptable with RSD% values less than 2%. The recoveries ranged from 97.25 to 104.98% with RSD values <2%, within the acceptable limits. The active compounds were negatively correlated with the size of the fruit, and the growth characteristics were negatively correlated with some environmental factors. The results of this study can be used as basic data for the standard cultural practices and quality control of C. tricuspidata fruits.
