        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.

        To investigate residual pesticide levels in agricultural products contained in Meal-kits, 27 Meal-kit products were collected from marts, Meal-kit shops, and online stores in Incheon City, South Korea. Seventy-six vegetable and thirty-seven mushroom products were analyzed for residual levels of 339 pesticides. Residual pesticides were detected in 23 out of 76 vegetables and were not present in the 37 mushroom products. The residual pesticide detection rate was 20.4% (23/ 113 cases). The pesticides famoxadone 0.034 mg/kg (standard: 0.01 mg/kg or less, PLS) and fenpyroximate 0.302 mg/kg (standard: 0.01 mg/kg or less, PLS) exceeded their maximum residue levels (MRL). This survey revealed that various types of pesticides remain in agricultural products in Meal-kits. Due to the nature of Meal-kit products, there is no separate standard for residual pesticides in agricultural products. Therefore, continuous monitoring of residual pesticides is necessary.

        Technological breakthroughs, combined with the demographic challenges of an aging population and the aftermath of the COVID-19 pandemic, spur new business opportunities in the service robot industry. From a management perspective, these technologies are positively evaluated in terms of increasing productivity, new business opportunities, and financial benefits (Belanche et al., 2020). However, although automation and robotics have already gained attention in the tourism and hospitality industry, research on their use in restaurants and the customer's attitude toward these new service solutions is still limited (Berezina et al., 2019; Ivanov et al., 2019; Kuo et al., 2017).

        The purpose of this study was to examine changes in serving frequency of elementary school meal before and after the COVID-19 pandemic. Number of menus provided in June and July of 2019 and 2020 were compared for 300 elementary schools in Korea. As a result, the serving frequency of la carte and dessert was increased after COVID-19. In addition, frequencies of main dishes such as pork cutlet, chicken, sweet and sour pork, hamburger steak, and so on using processed food were increased after COVID-19. Because of the longer serving time due to staggered serving, cook's working time for serving meals became longer. Therefore, it was judged that the number of servings of processed food was increased rather than the menu with a large amount of preprocessing work. Moreover, among desserts, fruits showed increased serving frequency. Serving frequencies for juice and dairy products were also increased. However, increased servings of juice and dairy products could increase sugar intake. Thus, a careful plan for menu composition is needed to provide balanced nutrients to students under emergency situations such as an infectious disease.

        Sustainable and healthy diet is a challenge in recent world. Despite the global depletion of water resources, Korea has no system for controlling its water footprint. This study established the water footprint tables of Korean food using the Water Footprint Network databases, and applied them into two meal plans for 19~64 year-old adults recommended in the Dietary Reference Intakes for Koreans 2020. Nut, oil, and meat’s water footprints were higher and those of fruit and vegetable were lower. Sesame oil had the highest water footprint of 21,793 L/kg and pineapple had the lowest domestic water footprint of 102 L/kg. Water footprint of one serving size of beef was 925 L, that of chicken was 260 L, and those of soybean were 43 L in global and 81 L in domestic. The water footprint of the recommended 2,400 kcal meal plan was 2,882 L, and that of 1,900 kcal meal plan was 1,915 L. The water resources can be saved by choosing food with lower water footprint. The results of this study can be used in the further researches for more sustainable and healthier Korean diet.

        This study was conducted to explore the change in the market issues on HMR (Home Meal Replacements) using local foods after the COVID-19 outbreak. Online text data were collected from internet news, social media posts, and web documents before (from January 2016 to December 2019) and after (from January 2020 to November 2022) the COVID- 19 outbreak. TF-IDF analysis showed that ‘Trend’, ‘Market’, ‘Consumption’, and ‘Food service industry’ were the major keywords before the COVID-19 outbreak, whereas ‘Wanju-gun’, ‘Distribution’, ‘Development’, and ‘Meal-kit’ were main keywords after the COVID-19 outbreak. The results of topic modeling analysis and categorization showed that after the COVID-19 outbreak, the ‘Market’ category included ‘Non-face-to-face market’ instead of ‘Event,’ and ‘Delivery’ instead of ‘Distribution’. In the ‘Product’ category, ‘Marketing’ was included instead of ‘Trend’. Additionally, in the ‘Support’ category, ‘Start-up’ and ‘School food service’ appeared as new topics after the COVID-19 outbreak. In conclusion, this study showed that meaningful change had occurred in market issues on HMR using local foods after the COVID-19 outbreak. Therefore, governments should take advantage of such market opportunity by implementing policy and programs to promote the development and marketing of HMR using local foods.

        The study was aimed to investigate the operational meal costs by kindergarten size in Seoul and to analyze recognition for optimal meal prices. A survey (31.6% recovery rate) was conducted on all kindergartens (779 kindergartens) in Seoul on April 2021 using descriptive analysis, t-test, and dispersion method. A price sensitivity measurement (psm) method was used to determine optimal meal prices. Result showed an average food cost for kindergartens of 2,647 won, an average labor cost of 605 won, an average operating cost of 146 won, and the total meal cost of 3,506 won. Total meal cost decreased with increasing kindergarten size (p<0.001). On the other hand, kindergartens with more students decreased the ratio of food cost to total meal cost, and operating cost and labor costs (p<0.001) increased. The optimal price of kindergarten operators' meal cost (OPP) was KRW 3,673. Furthermore, the analysis showed the sensitivity of operators' meal costs to kindergarten size was insignificant.

        This study was conducted to provide basic data for product development and marketing strategies for the Thai home meal replacement (HMR) market, to reflect the changing trends in household sizes in Thailand. The results of analyzing the characteristics and differences of HMR consumption behavior between single-person households and multi-person households in Thailand were as follows: It was found that single-person households use HMR to save money and for the convenience in cooking and preparation. In the preference by HMR type, multi-person households showed a higher preference for all types of products than single-person households. Thai consumers, regardless of their household size, mainly use department stores and large shopping malls to purchase HMR, and they most prefer to get information through Internet advertisements. The shelf life, quality, taste, hygiene, and freshness of HMR were the main considerations for their selection. Based on the results of this study, the Thai market requires the development of HMR products that are reasonable in terms of cost and preparation time. In addition, it is necessary to develop products that can satisfy consumer needs, such as nutritional enhancement and therapeutic foods, products that are organic, eco-friendly, cater to various menus, and address the premium segment.

        This study was undertaken to compare meal skipping, snacking, and weight perceptions between students on-campus living alone and off-campus living with parents, in an urban college in the United States. The self-report survey was completed by 219 college students (on-campus=100, off-campus=119) between April and May 2012. Two-thirds (67%) of the respondents skipped at least one meal in the past week, and most participants showed strong desires to lose weight despite their normal/under-weight status. Significant differences between the two groups were obtained for the reason to skip a meal and the type of snack consumed. Compared to on-campus students, significantly higher values were obtained for off-campus students for choosing ‘no time to prepare’ as a meal skipping reason for lunch and dinner, and ‘sweets’ as a preferred snack. In addition to the group comparison, multiple regression results indicate that the body mass index (BMI) positively correlates with meal skipping and snacking frequencies. Younger students and female students were determined to have a higher frequency of meal skipping and morning snacking. Future research is required to study the dietary factors associated with living arrangements, to help college students develop healthy eating habits.

        Gabion was unfavorable to the reconstruction of the landscape caused by limit plant growth because of commonly filled with stone. Therefore, gabion was need substrate as possible to plant growth for harmonize with the surroundings and prevent of erosion. The objective of this study was to evaluate the effect of substrates based growing media containing wood meal on physical property (moisture content), chemical properties (organic matter and C/N ratio), plant cover and plant species in gabion. The substrates were composed of soil and soil mixed with growing media (9:1 (v/v) and 4:1 (v/v)). The growing media was prepared by mixing the basic materials, such as peat, perlite, with the specific materials, such as steam treated wood meal (Quercus mongolica) and NH4NO3. Field experiments were carried out on a damaged forest slope, South Korea, from January to November. The results, the moisture content of soil mixed with growing media (4:1, v/v) was maintained high value than others during the thermophilic period and consistently high organic matter which at an advantage for long term plant growth for 11 months. We were confirmed soil mixed with growing media (4:1, v/v) was an advantage to keep C/N ratio for plant growth period. The growing media based substrates has high plant cover percentage and advantage to plant growth for long term. And to conclude, in general the project is a success considering that few repairs or follow up will be necessary. This technique offers a solution to create a better harmony with the surrounding environment.
