After the onset of the COVID-19 pandemic, there has been an explosive increase in restaurant meal delivery or takeout. The purpose of this study was to analyze the consumer perception of food safety and its influence on the purchase of delivery or takeout food from restaurants. This study, the 2020 Consumer Behavior Survey for Food (CBSF), was conducted from June 10 to August 21 2020. A total of 6,355 responses were used for the analysis. The results were as follows: First, the differences in consumer perception about food safety were analyzed according to whether they used delivery or takeout. Concern about food safety, satisfaction with dietary habits, and the ability to maintain safe dietary habits were higher in the non-user group. Except for food at home, the perception about food safety at other locations was higher in the user group. Food hazards such as antibiotics were perceived to be safer in the user group. Second, the perception of food safety affecting use of delivery or takeout was analyzed. It was found that the usage of delivery or takeout increased when the perception of the safety of home meal replacement (HMR), delivery or takeout food, and the ability to be informed about the harmful factors of agricultural products increased. The findings of this study may offer the basis for the food and food service industry to consider safety issues seriously and develop strategies to lead to feasible practices. Further, this study also supports the direction of the government toward strengthening the safety of new segments which have shown explosive growth in the COVID-19 era.

The purpose of this study was to compare differences between essential tasks and delegable tasks among public kindergarten dietitians. A survey study was conducted through a self-administered online method from November 18 to December 28, 2019. The survey consisted of essential tasks and delegable tasks, including 6 Duties, 25 Tasks, and 94 Task Elements. The survey was distributed to a sample of 500 kindergartens in Korea, after excluding incomplete surveys and outliers, and a total of 224 responses were used for the analysis. Descriptive statistics were used to compare essential tasks and delegable tasks. The results show that ‘Duty A. Nutrition Management’, ‘Duty B. Foodservice Management Practices’, ‘Duty C. Hygiene management of kindergarten foodservice’, ‘Duty D. Nutrition-Diet Education and counseling’, and ‘Duty F. Professionalism Enhancement’ were recognized as essential tasks to be performed by kindergarten dietitians. All 16 tasks elements (100.0%) in ‘Duty E. Managing snacks during semesters, and lunch/snack during breaks’ were identified as delegable tasks. In conclusion, most tasks were recognized as essential tasks to be performed by kindergarten dietitians. On the other hand, ‘Duty E. Managing Snacks during semesters, and lunch/snack during breaks’ was considered a delegable task by public-attached kindergarten dietitians. It is recommended that public-attached kindergartens should consider additional workforce related to ‘Duty E’. This study is expected to offer basic data on laws and regulations about the duties of kindergarten dietitians.

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.

This study examined the effects of social identity (cognitive, affective, and evaluative social identity) on affective commitment and behavioral intention in premium food markets. Data were collected from customers who had visited the premium food markets within three months prior to the time of the survey. A total of 247 responses were analyzed using SPSS 25.0 for Windows. The three attributes of social identity (cognitive, affective, and evaluative social identity) had a significant positive effect on the affective commitment, while affective commitment had a positive effect on the behavioral intention in premium food markets. On the other hand, only evaluative social identity had a significant positive effect on the behavioral intention in premium food markets. These results revealed the mediating effect of affective commitment in the relationship between social identity and customers' behavioral intention. This suggests a positive affective commitment as a key factor for customers in premium food markets. The results would be applied to marketing strategies based on the attributes of premium food market customers.

A standardized evaluation framework was developed for contract food service operations to analyze the priority of evaluation factors from the perspectives of contracting organizations (CO) and food service providers (FP). The Delphi technique and the Analytic Hierarchy Process (AHP) were used to identify and prioritize evaluation factors reflecting both perspectives. A three-round Delphi survey with 22 experts from academia and industry yielded seven evaluation areas and 46 indicators. Subsequently, an AHP survey was conducted with 40 experts (20 from CO and 20 from FP). The composite weights showed that “quality of menu and food” was rated highest by both parties (CO: 0.0699, FP: 0.0572), followed by “safe hygiene management” (CO: 0.0622, FP: 0.0366). Although CO prioritized “comfort and cleanliness of dining environment” (0.0344) and “meal distribution efficiency” (0.0341), FP emphasized “customer communication and satisfaction” (0.0316) and “food service operation management” (0.0302). By contrast, the lowest-ranked indicators included “carbon emissions management” (CO: 0.0120, FP: 0.0087), “ethical supply chain management” (CO: 0.0110, FP:0.0092), and “use of eco-friendly food materials” (CO: 0.0114, FP: 0.0101). Therefore, although traditional indicators remain dominant, sustainability and digitalization are still emerging in the evaluation framework. This study offers practical insights for enhancing objectivity and transparency in contract food service evaluation.The proposed framework integrates both perspectives, promoting mutual understanding and supporting the development of sustainable and efficient contract food service systems. Policy-level implications include aligning with public-sector evaluation models and environmental, social, and governance (ESG) mandates.

The purpose of this study was to examine restaurant customers' use of menu labeling and their perception of menu labeling attributes. Further, the study investigated relations of menu labeling use behavior, and perception of menu labeling attributes with behavioral intentions toward menu labeling. Using a self-administered survey conducted for 2 weeks from the 2nd week of October, 2015, data were collected from restaurant customers who were exposed to menu labeling over 3 months at the time of the survey. A total of 426 respondents completed the survey. Respondents were asked about use of menu labeling, usefulness, ease of understanding, accuracy, and demographic information. There was a difference in menu labeling use behavior according to age, whereas respondents aged 50 years or over showed significantly higher use of menu labeling than those in 20s (P<0.001). Perceptions of menu labeling attributes positively affected behavioral intentions towards menu labeling. While all three menu labeling attributes, ‘usefulness’, ‘ease of understanding’, and ‘accuracy’, were positive factors for behavioral intentions towards menu labeling, usefulness was the biggest attribute explaining behavioral intentions (P<0.001). The study findings offer implications that can be applied to academics, the foodservice industry, and government in an attempt to nurture a healthy eating environment through provision of nutritional information at restaurants.

OBJECTIVES: This study investigated the prevalence of trauma and posttraumatic stress disorder (PTSD) in patients with schizophrenia and compared the clinical outcomes in the PTSD group and the non-PTSD group. METHODS: Among 38 patients, a total of 35 schizophrenic patients completed the Positive and Negative Syndrome Scale (PANSS), Life Stressor Checklist-Revised (LSCL-R), and Clinician-Administered PTSD Scale (CAPS). RESULTS: Thirty three patients (94.2%) had at least one trauma and average 3.9 traumatic events in their life time. There were 12 patients (34.3%) who were diagnosed with PTSD. There were no differences of sociodemographic, duration of illness, number of admission, and duration of admission between the PTSD and non-PTSD groups. After one year treatment, the non-PTSD group had significantly improved in PANSS positive, negative, and general psychopathology scale. However, the PTSD group demonstrated no significant changes in PANSS negative and general psychopathology scale. CONCLUSION: In this study, there were high rate of prevalence of trauma and PTSD in patients with schizophrenia. PTSD had negative effects on clinical outcomes in patients with schizophrenia. Careful trauma-focused approach is necessary within this population.
