Food service industry in the era of COVID-19: trends and research implications
Seoki Lee,Sunny Ham 한국영양학회 2021 Nutrition Research and Practice Vol.15 No.S
Coronavirus disease 2019 (COVID-19) is a new type of respiratory disease that has been announced as a pandemic. The COVID-19 outbreak has changed the way we live. It has also changed the food service industry. This study aimed to identify trends in the food and food service industry after the COVID-19 outbreak and suggest research themes induced by industry trends. This study investigated the industry and academic information on the food and food service industry and societal trends resulting from the COVID-19 outbreak. The most noticeable changes in the food industry include the explosive increase in home meal replacement, meal-kit consumption, online orders, take-out, and drive-through. The adoption of technologies, including robots and artificial intelligence, has also been noted. Such industry trends are discussed in this paper from a research perspective, including consumer, employee, and organizational strategy perspectives. This study reviews the changes in the food service industry after COVID-19 and the implications that these changes have rendered to academia. The paper concludes with future expectations that would come in the era of COVID-19.

The development of information technology requires the conversion of paradigms in each part of the nation and the society. The improvement of teaching-learning system and its contents are on the rise in order to cultivate men of creative ability who lead an information-oriented society. To search out plans for improving learning ability in the field of the carbon compounds through the internet web sites, We analyzed a preceding scientific notion about the properties and the structure of the carbon compounds. We developed a teaching-learning plan ourselves by using the internet web sites and taught a class the unit of Carbon Compounds in chemistry II in an academic high school by using a computer, the medium of the advanced teaching. We examined and compared the differences and the durability of the transition of the students' notion after following the steps of the teaching-learning plan using the internet. The result is that the class for experimentation understood the scientific notions better than the controlled class. As a result, we can improve the students' learning ability in learning the properties and the structure of carbon compounds by applying apply the teaching learning plan using the internet web sites to a class. We are sure if we apply the method using the internet to the class, students are not only interested in studying chemistry but also able to understand the cubic structure and the properties of a chemical compound better.
NUTRITION INFORMATION DISCLOSURE: WHICH BRAND SHOULD BE MORE NERVOUS? MCDONALD'S OR SUBWAY?

The purpose of this research was to examine simultaneously health halo and health horn effects across two fast food restaurant brands that have healthful or unhealthful images (i.e., McDonald's and Subway). Specifically, we investigated the moderating effects of nutrition information disclosure and dietary restraint on behavioral intention of four menus from the two brands. Two menus from the McDonald’s and two menus from the Subway, respectively, had been selected as stimuli, and each menu represented health halo confirmation (the Roast-Chicken sandwich) / disconfirmation (the Italian-Spicy sandwich), and health horn confirmation (the Big Mac burger) / disconfirmation (the McSpicy-Cajun burger), respectively. This study employed a mixed factorial design: 2 (nutrition information: present vs. absent) X 2 (dietary restraint: restrained eater vs. unrestrained eater) X 4 (menu type: a health halo or a health horn (for the Subway and the McDonald’s with objective healthfulness). The survey was conducted on October 11- 17, 2016, by a research company, Macromill EMBRAIN in Korea, which possessed more than 1 million panel members. Cell sizes were 149 and 146 for the between-subjects factor. Participants were randomly assigned to one of the nutrition information disclosure experimental conditions (either present or absent) and presented with all four menus. The results showed that the behavioral intentions of all three menus, except health horn disconfirmation menu, were decreased. In particular, the effect size of health halo disconfirmation menu (decrease in behavioral intention) was the greatest. There was no difference in the behavioral intention of four menus between the restrained eater and unrestrained eater. Thus, brands positioned as healthy should well manage the expectation levels of their customers. A brand positioned as healthy, such as the Subway, has to manage the health expectation of its customer not get too high, or the brand has to continuously strive to satisfy its client's expectations. A brand positioned as unhealthy (eg, McDonald’s) needs to actively develop low-calorie menus, healthy menus or similar side dishes. Although indulgent menus would account for the majority of the revenue, existence of healthy menus / side dishes would lessen the guilty feelings of the customers of the restaurant and the brand. This is the first study which identified both the health halo effect and the health horn effect on restaurant brand image. The results of this study confirm the need to provide nutrition information on dining out menus and would help consumers choose healthy menus.

The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated protein (Cas9) system can be applied to produce transgenic pigs. Therefore, we applied CRISPR/Cas9 system to generate FoxN1-targeted pig parthenogenetic embryos. Using single guided RNA targeted to pig FoxN1 genes was injected into cytoplasm of in vitro matured oocyte before electrical activation. In results, regardless of the concentrations of vector, the cleavage rate were significantly (p<0.05) decreased (4 ng/μl, 51.24%; 8 ng/μl, 40.88%; and 16 ng/μl; 45.22%) compared to no injection group (70.44%). The blastocyst formation rates were also decreased in vector injected 3 groups (4 ng/μl, 7.96%; 8 ng/μl, 6.4%; and 16 ng/μl; 9.04%) compared to no injection group (29.07%). In addition, the blastocyst formation rates between sham injected group (13.51%) and no injection group (29.07%) also showed significant difference (p<0.05). The mutation rates were comparable between groups (4 ng/μl, 18.4%; 8 ng/μl, 12.5%; and 16 ng/μl; 20.0%). The sequencing analysis showed that blastocysts derived from each group were successfully mutated in FoxN1 loci regardless of the vector concentrations. However, the deletion patterns were higher than the patterns of point mutation and insertion regardless of the vector concentrations. In conclusion, we described that cytoplasmic microinjection of FoxN1-targeted CRISPR/Cas9 vector could efficiently generate transgenic pig parthenogenetic embryos in one-step.

In recent years, the marketing literature has given considerable attention to the concept of online consumer misbehaviour. However, this increased interest has resulted in a significant accumulation of knowledge, leading to fragmentation and confusion in the field. This situation has serious implications for both researchers and practitioners, as it impedes the development of a coherent and unified understanding of the field. To address this issue, this paper presents a systematic review aimed at consolidating and organizing the available research on online consumer misbehaviour. The paper provides a conceptualization and operationalization of the concept of OCM. Additionally, the paper identifies and discusses the existing theories used in the field of OCM research.
