The purpose of this study was to develop a computer software program for nutritional assessment using a Semi-Quantitative Food Frequency Questionnaire (SQFFQs) and the 24-hour Recall Method. The software for the SQFFQ was divided into input, output, and database. For dietary analyses, recipe and food databases were used. The recipe database included 25 items and the food database was divided into 18 food groups. The food database was composed of 19 general nutrient items, 33 fatty acids, and 18 amino acids. The software developed in this study can be summarized as follows: 1) input items related to the individual s ages information, lifestyle, biological values, and dietary habits; 2) individualized data in percent of the Korean RDA, the energy ratios of carbohydrates, proteins and fats, the ratio of animal to plant source intakes, and the distribution of food group intakes; 3) Statistical data on the individual's information, lifestyle, biological values, and dietary intakes including the frequency of intake of cooked foods, the amounts of food, and the number of food groups, and nutrients. In the 24-hour Recall Method, the input and output consisted of the individual s information and cooked dish intakes. The individual s report included the amounts of nutrient intake according to number of meal and days, in comparison to the Korean RDA, the energy ratio for carbohydrates, proteins and fats, the ratio of animal to plant source intakes, and the distribution of food group intakes. The statistical report presented the number of food groups and foods, and the nutrient intakes. To evaluate the validity of the SQFFQ, the Spearman Rank Order Correlation and kappa values were used. As a result, correlation coefficients comparing the 24-hour Recall Method appeared to be more than 0.5, except for vitamin $B_1, B_2$, niacin, and vitamin E. The kappa values for energy and carbohydrate intakes were both 0.7, and protein, fat, vitamin C, folate, Ca, and iron intakes ranged from 0.3 to 0.7.

Background: Musculoskeletal pain is associated with obesity; however, information on factors associated with pain in adults with obesity and severe obesity is limited. The purpose of this study was to assess the prevalence of musculoskeletal pain by site and intensity of pain and associated factors in individuals with severe obesity (body mass index ≥ 35.0 kg/㎡). Methods: Baseline data from the DieTBra Trial study evaluating pain symptoms in nine body regions over the last seven days using the Nordic Questionnaire on Musculoskeletal Symptoms and Numerical Pain Scale. The variables analyzed using multiple Poisson regression with hierarchical analysis were: sociodemographic, lifestyle, food consumption, clinical, and anthropometric, and the outcome was moderate and intense pain. Results: In 150 participants, there was a high prevalence of ankle and foot pain (68.7%), lower back pain (62.7%), pain in the knees (53.3%) and upper back pain (52.0%), with a predominance of intense pain. Factors associated with pain according to specific sites were: type 2 diabetes with hand/wrist pain; sedentary time with hip pain; insomnia with pain in the hip and knee; edema in the lower limbs with pain in the lower back and ankles/feet; degree of obesity with ankle/foot pain; and percentage of total fat with ankle/foot pain. Conclusions: There was a high prevalence of pain and intense pain in individuals with severe obesity and an association with clinical variables, the degree of obesity, and sedentary lifestyle.

Purpose: In this study, we comparatively investigated the nutrition knowledge, dietary attitude, and dietary behavior related to salt according to the types of dietary life style for differences between the groups. Methods: The survey was conducted between May 1 to July 31, 2014 among 500 adults aged >19 years in Seoul, Gyeonggi-do and Chungcheong-do areas. Results: Factor analysis of the dietary life style, indicated 4 factors including food convenience factor, food information emphasis factor, behavior factor of pursing food taste, and food purchase standard factor, which were classified into 3 groups according to differentiated dietary life style types; group 1 emphasized convenience and diversity of food, and price sensitiveness. and included subjects who had low interest in health and nutrition and were less likely to take care of their health through regular exercise,; group 2 emphasized food ingredients, food additives, usage and food purchase standards. and included subjects who were more likely to take care of their health through exercise and showed lower intake of fast food and less cases of eating out.; and group 3 showed relatively higher tendency toward dietary life style factors than the other two groups. The level of nutrition knowledge in sodium intake differed according to dietary life styles, and showed a significant difference in the dietary practice of sodium intake. Conclusion: Nutrition education on the healthy dietary habit of reducing sodium intake be based on ge and gender. In addition, an effort is required to improve behavior, interest, and attitude according to the important tendencies of the dietary life style.

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.

BACKGROUND/OBJECTIVES: Coronavirus disease 2019 (COVID-19) cases were first reported in December 2019, in China, and an increasing number of cases have since been detected all over the world. The purpose of this study was to collect significant news media reports on food services during the COVID-19 crisis and identify public communication and significant concerns regarding COVID-19 for suggesting future directions for the food industry and services. SUBJECTS/METHODS: News articles pertaining to food services were extracted from the home pages of major news media websites such as BBC, CNN, and Fox News between March 2020 and February 2021. The retrieved data was sorted and analyzed using Python software. RESULTS: The results of text analytics were presented in the format of the topic label and category for individual topics. The food and health category presented the effects of the COVID-19 pandemic on food and health, such as an increase in delivery services. The policy category was indicative of a change in government policy. The lifestyle change category addressed topics such as an increase in social media usage. CONCLUSIONS: This study is the first to analyze major news media (i.e., BBC, CNN, and Fox News) data related to food services in the context of the COVID-19 pandemic. Text analytics research on the food services domain revealed different categories such as food and health, policy, and lifestyle change. Therefore, this study contributes to the body of knowledge on food services research, through the use of text analytics to elicit findings from media sources.

In the 21st century, informatization is playing a huge role in people's lives. Korea is experiencing the tremendous changes in social structure and lifestyle caused by informatization. This paper focuses on economic phenomena rather than discussion on social structure due to informatization. We check whether the Goodwin model, which can comprehensively express economic growth, economic cycle, and income distribution, is suitable for the Korean economy in the information age. This model is simulated by selecting a quantitative economic methodology that estimates coefficients from time series data of the Korean economy. The simulation results confirmed that the Goodwin model is suitable for analyzing functional income distribution in Korea.

Mitochondrial dynamics and distribution is critical for their role in bioenergetics and cell survival. We investigated the consequence of altered fission/fusion on mitochondrial function and motility in INS-1E rat clonal ${\beta}$-cells. Adenoviruses were used to induce doxycycline-dependent expression of wild type (WT-Mfn1) or a dominant negative mitofusin 1 mutant (DN-Mfn1). Mitochondrial morphology and motility were analyzed by monitoring mitochondrially-targeted red fluorescent protein. Adenovirus-driven overexpression of WT-Mfn1 elicited severe aggregation of mitochondria, preventing them from reaching peripheral near plasma membrane areas of the cell. Overexpression of DN-Mfn1 resulted in fragmented mitochondria with widespread cytosolic distribution. WT-Mfn1 overexpression impaired mitochondrial function as glucose- and oligomycin-induced mitochondrial hyperpolarization were markedly reduced. Viability of the INS-1E cells, however, was not affected. Mitochondrial motility was significantly reduced in WT-Mfn1 overexpressing cells. Conversely, fragmented mitochondria in DN-Mfn1 overexpressing cells showed more vigorous movement than mitochondria in control cells. Movement of these mitochondria was also less microtubule-dependent. These results suggest that Mfn1-induced hyperfusion leads to mitochondrial dysfunction and hypomotility, which may explain impaired metabolism-secretion coupling in insulin-releasing cells overexpressing Mfn1.

Fashion style in movies delivers their image the atmosphere and becomes the means for containing the personality, spiritual world and inner thinking the characters in the movies and including its plot. When the American new cinema emerged in late 1960's and early 1970's in the American movie history, the new left wing which wants to overturn adult generation and the hippie culture which wants to escape from an existing system also emerged. Therefore, this study analyzed the fashion style in the movie 'Easy Rider (1969)', i.e. the representative new American movie which showed the isolation from adult generation and negative realities of the American society. From the movie, we can understand the young generation after the Vietnam war, i.e. baby boom generation, pursued the hippie culture as their young culture. With their strong self-consciousness, they formed their own lifestyle and values which are different from those of adult generation, and we can understand clothes were used as a tool to express their value system.

The outbreak of COVID-19 has changed our lifestyle. People spend much more time on YouTube, SNS and online shopping than before. Accordingly, the number of product review videos are steeply increasing in YouTube platform. When people watched the review videos, they might search additional information if they liked the videos. This study aims to investigate how the informativeness and the degree of attention gathering of product review videos influence on the product information sourcing intention and persuasion knowledge. We also try to find whether prior YouTube experience affects the relationship between the degree of attention gathering and persuasion knowledge. We conducted an online survey on 499 participants and analyzed using partial least square methods. Results show that 1) informativeness and the degree of attention gathering towards product review videos influence on the product information sourcing intention and user's persuasion knowledge. 2) Viewers' YouTube experiences moderate the increase of the viewers' persuasion knowledge caused by increasing the degree of viewers' attention gathering. This study implies that YouTube product review videos could be created in strategic manners. Also, it could be inferred that consumers' prior YouTube experiences may reduce negative potentials of the degree of attention gathering onto persuasion knowledge.

Previous studies have shown that five representative behaviors affect the health of adults in everyday life : smoking, drinking, exercise, nutrition, and stress. This study focuses on these five behaviors in an attempt not only to develop a program that promotes health, but also to suggest ways that such a program may be implemented to reflect diverse lifestyles. Our aim is to show how individual subjectivity influences behavior when making lifestyle choices that affect health. By analyzing individual characteristics, we tried to group people according to their common attitude and behaviors to promote health. We hope that this study may provide the fundamental data which may be used to assist professionals in promoting healthy behaviors among adults. In order to examine how subjectivity(e.g, personal opinions or attitudes) influences behavior, we prepared Q-statements which were composed of Q-samples for the study of human subjectivity. We polled forty-two adults and then analyzed the results using a PC qunal program. As a result, the respondents were classed according to six different types. Type One includes people who think managing stress is the most effective way to live a healthy life. They regard smoking and drinking as harmful behaviors. Type Two subjects, on the other hand, regard smoking and drinking as a matter of taste with few harmful effects. Although they recognize the importance of managing stress, they have a positive attitude towards smoking and regard nutrition as a minor factor in promoting their healthy lifestyle. Those classed as Type Three emphasize the necessity of exercise. They perceive drinking, smoking, and stress as harmful. People in this category seek to increase physical strength and to regulate all five health behaviors by keeping them in a normal range. Type Four consists of people who are indifferent to their health. While they seem to recognize the importance of regular exercise, they pay little attention to nutrition or to the harmful effects of smoking, drinking, and stress. They believe that exercise alone is sufficient to maintain their health. Type Five subjects believe drinking is not a harmful behavior at all. Rather. it has a positive effect on their mental health. They are characterized by this positive attitude towards drinking as well as by indifference toward nutrition (although they readily admit that good nutrition is important). Finally. those classed as Type Six have a positive attitude toward moderate drinking as a means to relieve stress. However. they also recognize the harmful effects of excessive drinking. They regard good nutrition as an important lifestyle choice but are indifferent toward exercise. This type is engaged in passive health management. This study devised six types or categories that reflect different attitudes toward promoting health in everyday life. It further went on to analyze the characteristics of each type. This study shows that programs designed to promote health must be modified to reflect the diversity of individual attitudes and patterns of behaviors.
