This study aims to analyze consumers' purchase decision-making process of buying avatar fashion items on the Metaverse platform. Drawing on the connection between the self-expression tendency of the MZ generation and that of avatars in the Metaverse, this study uses a qualitative research method to analyze how consumers express their self-image through the appearance of their avatars. Unlike previous studies on the clothing purchase decision-making process, this study shows that purchasing and consumption behavior involve the following six stages: recognizing desire, collecting information, evaluating alternatives, making purchases, evaluating the consumption, and post-purchase action-taking. In the first stage of the purchase decision-making process, consumers' desire arises with self-image expression and confirmation. In the second stage, consumers have a high tendency to shop in the best item category. In the alternative evaluation stage, consumers tend to seek items that match their highest standard while considering their personal preferences. In the fourth stage, when making actual purchases, unplanned purchase behavior often occurs along with an active practice of alternative evaluation. In the fifth stage, the evaluation of the consumption shows that consumers achieve satisfaction by applying a style to their avatars that they are unable to try in the real world. In the last stage, consumers often use their purchases to communicate their various styles with other online consumers. Therefore, we conclude that the online purchase decision-making process differs from the offline process as it is divided into six stages.

BACKGROUND/OBJECTIVES: Metabolic syndrome is closely associated with lifestyle factors, including diet and nutritional intake. Modern trends show a shift in food consumption from healthy home-cooked meals to processed and instant foods. Therefore, this study analyzed the association between ultra-processed food intake and the development of metabolic syndrome in Korean adults based on the data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2013-2018. SUBJECTS/METHODS: The subjects of this study were 17,414 adults aged 19-80 years who participated in the 6th-7th KNHANES. Processed food was classified into four categories, NOVA1 to NOVA4, using 24-h recall data. The higher the NOVA category, the more processed the food. Statistical analysis was conducted using logistic regression to investigate the prevalence of metabolic syndrome according to the consumption of ultra-processed foods. RESULTS: Among the diagnostic criteria for metabolic syndrome, hypertension (odds ratio [OR], 0.72; 95% confidence interval [CI], 0.62-0.85; Q4 vs. Q1, P-trend < 0.001) and high triglycerides (OR, 0.83; 95% CI, 0.72-0.94; Q4 vs. Q1, P-trend < 0.001) showed a correlation with the percentages of energy consumed from ultra-processed foods. The OR for metabolic syndrome, according to the percentages of energy consumed from ultra-processed foods, is shown only for men. The OR showed that the percentages of energy consumed from ultra-processed foods were associated with increased metabolic syndrome. CONCLUSIONS: This study suggests that consumption of ultra-processed foods raises the risk of metabolic syndrome especially among men. To prevent metabolic syndrome, it is necessary to prepare appropriate dietary guidelines for Korean adults.

Since national mid-term target for GHG reduction was determined in 2009, various efforts in transportations have been prepared. Generally, the GHG emission of transportation is calculated using the emission factor published from IPCC guideline(2006). However, it is necessary to develop new emission factors considering the properties of transportation as well as fuel. In Korean railroad, main emission sources are the consumption of diesel and electricity from railcar operation. The GHG emission of electric-powered railcars can be estimated using national electric emission factor, but diesel-powered railcars show different trends. The purpose of this study was to establish the development plans of emission factors for diesel-powered railcars. As a result, the emission factors of diesel-powered railcars were classified into railcar type, engine type and life cycle, notch, load, and traffic volume. In future, several emission factors with this category will be presented quantitatively through field tests with the order of priority.

Despite a copious volume of work on the relationship between social class and cultural consumption, scholars have paid scant attention to the increasingly apparent observation that a vast majority of the population exhibits indifference toward fine arts regardless of one's socio-economic status. Much of the prior literature on cultural consumption has treated the public's indifference to fine arts not as a distinct analytical category that deserves an explanation of its own, but simply as the opposite of "likes" or the act of consumption, let alone being disentangled from the concept of "dislikes" in taste-formation and consumption behavior. In this paper, we suggest that the seemingly increasing trend toward indifference to fine arts, especially among those who are part of the well-educated and economically well-off, merits close scholarly attention on its own term. As an initial step toward this endeavor, we explore the factors behind indifference toward fine arts among Korean middle-class, using the ground theory method. Our interview findings reveal that much of indifference toward fine arts is attributable to the lack of tastes in fine arts and artistic competence. Our results suggest that research drawing on Bourdieu's theory and Peterson's omnivore hypothesis needs to be further revised through an in-depth investigation of the institutional and societal contexts where art education takes place in Korea. We discuss the implications of our findings for policy-making in the cultural and artistic sphere.

The dairy industry has consistently grown via the expansion of dairy-based food categories. Dairy product consumption is stable since the nutrient composition in dairy products is ideal for human health. However, dairy products are highly susceptible to food-borne pathogens. Controlling the safety of dairy products is thus important when considering the nutrient-rich matrix of this food category. Currently, immunoassays or molecular biology techniques have been used to evaluate the safety of dairy products in Korea. These methods are based on the detection of proteins and thus have low reproducibility and sensitivity. Recent techniques to detect food-borne pathogens have focused on genetic analyses. Rapid detection methods for food-borne pathogens in milk and dairy products using polymerase chain reaction (PCR) techniques, such as conventional PCR, real-time PCR, repetitive sequence-based (rep)-PCR, PCR-denaturing gradient gel electrophoresis (DGGE), and digital PCR, are reviewed in this article. The aim of this review was to contribute knowledge of the relationship between microflora and the quality of dairy products. This study will also assist in the immediate monitoring of food-borne pathogens in milk and dairy products when an outbreak related to this food category occurs.

Objectives: The aim of this retrospective cohort study was to investigate whether non-alcoholic fatty liver disease (NAFLD) was associated with incident bone mineral density (BMD) decrease. Methods: This study included 4536 subjects with normal BMD at baseline. NAFLD was defined as the presence of fatty liver on abdominal ultrasonography without significant alcohol consumption or other causes. Decreased BMD was defined as a diagnosis of osteopenia, osteoporosis, or BMD below the expected range for the patient's age based on dual-energy X-ray absorptiometry. Cox proportional hazards models were used to estimate the hazard ratio of incident BMD decrease in subjects with or without NAFLD. Subgroup analyses were conducted according to the relevant factors. Results: Across 13 354 person-years of total follow-up, decreased BMD was observed in 606 subjects, corresponding to an incidence of 45.4 cases per 1000 person-years (median follow-up duration, 2.1 years). In the model adjusted for age and sex, the hazard ratio was 0.65 (95% confidence interval, 0.51 to 0.82), and statistical significance disappeared after adjustment for body mass index (BMI) and cardiometabolic factors. In the subgroup analyses, NAFLD was associated with a lower risk of incident BMD decrease in females even after adjustment for confounders. The direction of the effect of NAFLD on the risk of BMD decrease changed depending on BMI category and body fat percentage, although the impact was statistically insignificant. Conclusions: NAFLD had a significant protective effect on BMD in females. However, the effects may vary depending on BMI category or body fat percentage.

This study analyzes the current educational curricula in the field of Clothing and Textiles in order to develop appropriate educational methods and courses. We reviewed the curricula offered by 58 Clothing and Textiles Departments at four-year universities in Korea. We analyzed the educational content of each curriculum by dividing all of the courses offered into eight categories. The analysis was based on the information posted on the universities' Internet websites, and the analysis was performed by using descriptive statistics. The results of this study are as follows: First, the educational courses of the Clothing and Textiles Departments are composed of, 36.2% design, 20.4% production, and 14.5% textile categories. In comparison with the results of a similar study conducted in 1999, emphases on the design, distribution, and marketing categories have increased, while the emphases on the production, apparel material, basic knowledge, and consumption science categories have decreased. Second, in the case of the apparel material category, basic knowledge of materials constituted 18.5%, the largest part of the category. The average number of units offered in the area of apparel materials by the 58 Departments was 17 units per year. The curricula were found to vary by regions of the country. The universities located in the Chungcheong region offer more textile material courses, but the universities in the Capital region offer fewer textile material courses than other regions. Departments that are affiliated with universities that emphasize Art and Design have more courses on basic knowledge, dyeing and finishing, and fabric design than other universities.

This study analyzes the fashion video content of vegan YouTubers in order to understand how the vegan message is being conveyed in media. This study collected data with NoxInfluencer and conducted a case study of the vegan fashion YouTube content. We collected 143 videos for analysis as follows. The characteristics of vegan fashion content were divided into six categories. First, fashion know-how consisted of YouTubers' explanation on vegan fashion, from styling to where to buy vegan and fair trade products. Second, fashion haul content showed second hand products as well as certified vegan fashion products. Third, fashion daily life focused on a day in the life of a vegan YouTuber, casually showcasing fashion in real life. Fourth, fashion products reviews were about vegan YouTubers' thoughts and concerns about various vegan fashion brands and products. Fifth, fashion coordination category consisted of Lookbooks according to seasons. Last, the fashion entertainment category showed YouTubers challenging themselves to dress outside of their comfort zone. The content of the message was distinguished by consumption methods and aesthetic interaction. Also, vegan YouTubers were always anticipating the possibility of appealing to a wider demographic. This study differs from existing studies because it analyzed fashion YouTube content in order to understand the spread of a vegan message in the media environment. This study has its significance in suggesting the direction that the vegan community should take in delivering vegan messages in the future.

In an attempt to explore the consumption behaviors of customers regarding ethnic food restaurants the present study examined the effects of consumer characteristics, accessibility of ethnic food restaurants, product characteristics, and social factors on the customer behavior towards ethnic food restaurants, and further investigated the causal relationship between the customer behavior and his or her intent to reuse. A questionnaire survey was conducted approximately for a month with domestic consumers who had tried foreign cuisines. A total of 230 questionnaires were distributed and 215 questionnaires were collected, of which 210 were used in the final analysis excluding five due to inadequate responses. The finding of the study were as follows. First, of the consumers' lifestyles category the gourmet oriented did not yield significant effect on subjective norm or other consumption behavior, whereas the trend oriented had noticeable influence on both factors. Second, while consumers' diversity-seeking characteristic did not affect subjective norm, it affected consumption behavior of ethic food restaurants. The results seem to indicate that the diversity-seeking characteristic is more to one's individual attributes, rather than being influenced by others. Third, ethnic food restaurant's consumption accessibilities strongly influenced the subjective norm, suggesting that in using the ethnic food restaurants, the more convenient the accessibility is, the higher the possibility of use from influenced reference group. However, when consumers previously had not been exposed to ethnic cuisines, convenient accessibility was not able to overcome the barriers of consumer reluctance, nor directly shape positive behaviors. Fourth, while national uniqueness of ethnic food did not affect subjective norm, the uniqueness did have positive impact on consumption behavior of foreign ethnic food restaurants. Fifth, consumer's subjective norm positively influenced both consumption behavior of ethnic food restaurants and their intent for future use. Lastly, consumption behavior toward foreign ethnic food restaurants positively influenced consumer's intent for future use, indicating that it would be most imperative and effective to first help reinforce positive attitude in oder to encourage a more use of ethnic food restaurants.
