BACKGROUND/OBJECTIVES: The coronavirus disease 2019 (COVID-19) outbreak has dramatically changed nearly every aspect of our lives. Although Dietary lifestyle includes attitudes and behaviors to meet their most basic needs, but few studies have examined the pattern of changes in dietary lifestyle driven by COVID-19. This study explores changes in dietary attitudes and behaviors among Korean consumers after COVID-19. SUBJECTS/METHODS: An online survey was conducted with 549 Korean adults aged 20 and older to identify general demographics and changes in dietary attitudes and behaviors. Data were collected from Oct 12 to Oct 18, 2020. Frequency, percentage, and mean values were calculated and a K-means cluster analysis was performed to categorize consumers based on the 5S of dietary attitudes (i.e., savor-oriented, safety-oriented, sustainability-oriented, saving-oriented, and socializing-oriented). RESULTS: Findings indicate consumers considered safety, health, and freshness to be most important when choosing groceries and prepared meal such as home meal replacement and delivery food. Among the types of services, a large proportion of consumers increased their delivery and take-out services. Regarding retail channels, the increase in the use of online retailers was remarkable compared to offline retailers. Finally, consumers were classified into four segments based on changes in dietary attitudes: "most influenced," "seeking safety and sustainability," "abstaining from savor and socializing," and "least influenced." Each type of consumer exhibited statistically significant differences by sex, age, household composition, presence of disease, and perceived risk of COVID-19. CONCLUSIONS: This exploratory study provides initial insights for future research by identifying various aspects of dietary attitudes and behaviors among Korean consumers after COVID-19.

The development of the Internet has led to the emergence of an internet meme culture using duplication. This phenomenon has appeared in the fashion field as 'fashion memes' and its playful expression has helped it to spread. Vetements is one of the well-known brands that actively incorporates fashion memes into their fashion. The purpose of this study was to examine the playfulness of Mikhail Bakhtin's Carnival Theory and identify the playful identity, design characteristics, and implications of Vetements' fashion memes in light of Bakhtin's playfulness. The research methods were literature research and collection case analysis, and empirical content research was conducted in parallel. The scope of this study was fashion memes shown in the products from 2017 S/S to 2019 F/W. The study results showed that Bakhtin's playfulness could be divided into "playfulness in the destruction of hierarchy", "playfulness in grotesque imagery" and "playfulness in the emphasis on the lower bodily stratum". Based on these findings, the playful identity of Vetements' fashion meme images can be described as follows. First, it breaks down the existing order of fashion brands like the destruction of hierarchy in Bakhtin's theory. Second, it is grotesque; it is strange, eerie, yet ridiculous at the same time. Third, it is a playful metaphor of contamination, filth, and lower stratum. The modes of embodiment of such identity include Vetements' collaboration with famous brands, the use of cheap items, and the expression of genderless ideas.

The motivation behind consumers' voluntary participation plays a key role in determining the successful out-come of co-creation activities. This study, in the context of online-community-based co-creation, investigates the effect of consumers' motivation on continuance participation and advocacy intention by mediating perceived empowerment. We focused on analyzing the co-creation process of new product developments for beauty-related firms and platforms. A web survey was conducted on active users of the online beauty community who have participated in co-creation projects. A total of 226 responses were analyzed using SPSS 26.0 and AMOS 22.0 statistical programs. The findings illustrate that all motivations for participation (intrinsic, social, and financial) influenced perceived empowerment. This increased empowerment also positively affected continuance participation and advocacy intention for future co-creation projects. Furthermore, we explored the moderating role of the engagement period in the community regarding the relationship between participation motivation and empowerment. The results show, consumers with high intrinsic motivation greatly perceive empowerment when they have short-term engagement in the community; those with high social motivation strongly recognize empowerment when they have long-term engagement in the community. We provide valuable recommendations regarding how to make innovative co-creation experiences between beauty firms and consumers via an online-based community.

The purpose of this study is to design and develop a Metaverse ZEP platform-based teaching and learning process plan by selecting learning topics that are commonly dealt with among the core concepts of the "family" area of practical (technical and home) subjects. To this end, a teaching and learning process plan was developed through planning, Metaverse platform design, expert review, and revision stages. The Metaverse ZEP "Open Class Day" platform, a virtual learning space, was created and developed to further utilize EduTech programs, such as Padlet, Mentimeter, Jamboard, Miricanvas, and Spatial. The teaching and learning process plan developed in this study consists of a total of seven sessions, including approaching EduTech, Changing Families, Exploring Our Family, and Counseling Centers 1, 2, and 3. Among them, Geumji Counseling Center 1, 2, and 3 was designed as a class in which parents and children participate together in open classes using the ZEP platform. This platform can be used as part of parent classes as well as to encourage online participation in the open classes held periodically at each individual school. In terms of the content validity ratio (CVR) of the developed teaching and learning process verified through five experts, 12 out of 15 questions had a CVR of 1, while the remaining three questions had a CVR of 0.6. The three questions with lower validity were revised and supplemented.

Objectives: This study evaluated usual dietary intakes of total fat and fatty acids among the Korean population based on the revised Dietary Reference Intakes for Koreans 2020 (2020 KDRIs). Methods: This study utilized data from the eighth Korea National Health and Nutrition Examination Survey (KNHANES 2019-2021). We included 18,895 individuals aged 1 year and above whose 1-day 24-hour dietary recall data were available. To calculate the external variability using the National Cancer Institute 1-day method, data from the U.S. NHANES 2017-March 2020 Pre-pandemic dataset were employed. The total fat and fatty acid intake were evaluated based on the Acceptable Macronutrient Distribution Ranges (AMDRs) and Adequate intake (AI) of 2020 KDRIs for each sex and age groups. Results: Approximately 86% of the Korean population obtained an adequate amount of energy from total fat consumption (within the AMDRs), indicating an appropriate level of intake. However, the percentage of individuals consuming saturated fatty acids below the AMDR was low, with only 12% among those under 19 years of age and 52% aged 19 years and older. On a positive note, approximately 70% of the population showed adequate consumption of essential fatty acids, exceeding the AI. Nevertheless, monitoring the intake ratio of omega 3 (n-3) to omega 6 (n-6) fatty acids is essential to ensure an optimum balance. Conclusions: This study explored the possibility of estimating the distribution of nutrient intake in a population by applying the external variability ratio. Therefore, if future KNHANES conduct multiple 24-hour recalls every few years-similar to the U.S. NHANES-even for a subset of participants, this may aid in the accurate assessment of the nutritional status of the population.

Objectives: This study analyzed the factors related to outpatient service to Western medicine (WM) and Korean medicine (KM) of Korean adults with depressed mood using data from the 2019 Korea Health Panel Study. Methods: The general characteristics according to group of 827 individuals, and the factors influencing the use of integrative medicine (IM) medical service were identified using the Chi-square test and binary logistic regression results. The factors were classified based on the Andersen healthcare utilization model. The results of regression analysis were presented as odds ratio (OR) and 95% confidence interval (CI). Results: Among the individuals of the study, 658 (79.6%) were in the WM group and 169 (20.4%) were in the IM group. In the WM group and the IM group, the presence of suicidal ideation was common at 37.7% and 43.2%, respectively. As a result of regression analysis, the living in Busan/Daegu/Ulsan/Gyeongsang compared to living in Seoul/Gyeonggi/Incheon [OR = 0.522 (95% CI = 0.328 to 0.830)], and presence of musculoskeletal [OR = 1.686 (95% CI = 1.071 to 2.653)] and mood disorders [OR = 1.737 (95% CI = 1.106 to 2.726)] were the most influential factors on the use of IM medical service. Conclusions: This study is the first in Korea to analyze the patterns of medical institution use and factors used in KM treatment among adults with depressed mood. The results of this study provide preliminary evidence for the contribution of KM to national mental health in the context of depression.

TThis study explored the requirement of fabric sensor that can measure the motion of the joint effectively by measuring and analyzing the variation in electric resistance of a sensor in accordance with bending and stretching motion of the arm by the implementation of a motion sensor utilizing conductive fabric. For this purpose, on both sides of two kinds of knitted fabric, namely 'L' fabric and 'W' fabric Single Wall Carbon Nano-Tube(SWCNT) was coated, fabric sensor was developed by finishing them in a variety of ways, and the sensor was attached to the arm band. The fabric sensor consisted of total 48 cases, namely background fabric for coating, the method of sensor attachment, the number of layer of sensors, the length of sensor, and the width of sensor. The performance of fabric motion sensors in terms of a dummy arm, that is, a Con-Trex MJ with 48 arm bands around it was evaluated. For each arm band, a total of 48, fastened around the dummy arm, it was adjusted to repeat the bending and stretching at the frequency : 0.5Hz, ROM : $20^{\circ}{\sim}120^{\circ}$, the voltage was recorded for each case after conducting three sets of repeat measurement for a total of 48 cases. As a result of the experiment, and as a consequences of the evaluation and analysis of the voltage based on the uniformity of the base line of the peak-to-peak voltage(Vp-p), the uniformity of Vp-p within the same set, and the uniformity of the Vp-p among three sets, the fabric sensors that have been configured in SWCNT coated 'L' fabric / welding / two layers / $50{\times}5mm$, $50{\times}10mm$, $100{\times}10mm$, and SWCNT coated 'W' fabric / welding / two layers / $50{\times}10mm$ exhibited the most uniform and stable signal value within 5% of the total variation rate. Through all these results of the experiment, it was confirmed that SWCNT coated fabric was suitable for a sensor that can measure the human limb operation when it was implemented as a fabric sensor in a variety of forms, and the optimal sensor types were identified.

This study investigates the perceptions, Stages of Concern (SoC), and Levels of Use (LoU) regarding process-based assessment among Home Economics (HE) teachers to determine the necessary support for its implementation in schools. Data were gathered from a survey administered to HE teachers. The results are as follows. First, HE teachers viewed process-based assessment favorably, valuing its multifaceted evaluation approach over result-based assessment. The feedback from process-based assessments was seen as an opportunity for reflection for both educators and students. While some teachers expressed uncertainty about the optimal timing of implementation, they generally demonstrated a sound understanding of the feedback concept within the assessment process. HE teachers were predominantly concerned with their own professional expertise and the learning outcomes of their students. The majority of HE teachers have utilized process-based assessments for at least one semester. None deemed it irrelevant to their practice or showed disinterest in its adoption. Those who had yet to implement it were either in the first(introduction) or the second(preparation) stages.

Sciences and technologies are the sources which have formed presently highly developed civilizations and cultures and have enhanced the quality of human lives. But we see the dark sides of them as well as the bright sides, and we have the consciousness of environmental crisis and destruction of lives caused by them. Thus were are criticisms against human-tropism or technology-tropism from nature-tropism or deep ecology. However, if people would continue to have the desire of enjoying the present quality of their lives, they should try to develop and improve pro-environmental technologies. In this vein, we have the necessity of making environmental decisions and solving environmental problems by information technologies. Since the second half of the last century, 'environment' is the key word because we have the consciousness of environment strongly. As we solve human problems by making decisions of actions, we must face with environmental decisions in order to solve our environmental problems. If we have the better understanding of the nature of information and the role of information technology, and the relation of information technology and decision-making, we are able to design environmental systems and implement their optimal interfaces of environmental components. For this purpose, we are obliged to combine several useful technologies including GIS, DSS, Knowledge-based system and artificial neural networks. Therefore the developments and cooperations of these fields in environmental decision making enables us to live in the better and comfortable surrounding in the near future.
