This study was conducted to investigate whether there were differences in eco-friendly food, home meal replacement (HMR) purchases, and eating-out behavior according to the level of agri-food consumer competence. The data for the study were extracted from main food consumers (n=3,321) in the 2022 Food Consumption Behavior Survey. The competence index was divided into awareness-attitude-practice items, and three groups were classified by competence level. The results showed an agri-food consumer competency score of 70.62, with the highest score for awareness (73.96), followed by practice (69.28) and attitude (66.18). The frequency of purchasing eco-friendly food was higher in the excellent group compared to other groups, and quality and price satisfaction was higher with higher competency (p<0.001). Regarding HMR, the results showed that the shortage group had the lowest HMR consumption rate, and satisfaction decreased as competence decreased (p<0.001). The main reason for eating-out was to enjoy food in all groups (59.0%), followed by a lack of cooking time in the excellent group (15.7%) and hassle with food preparation in the moderate and shortage groups (17.3%, 16.6%) (p<0.001). In short, agri-food consumption competency showed differences by contents and components, and differences in food purchases and eating-out behavior by competency level were found.

The Purposes of this study were to assess high school students' nutrient consumption at the ordinary time and to analyze nutrient contents and nutrition consumption of lunch. The questionnaires for self-reported food consumption were distributed to 210 students enrolled in a boy's high school and a girl's high school located in Seoul area. A final response rate was 87.1%, excluding responses that had significant missing data. Data of self-reported food consumption and BMI(Body Mass Index) were analyzed with descriptive analysis and t-test using SPSS Win(ver. 12.0). To measure the serving size and the waste amount, data were collected for three meals in a three day period at each school. A weighed plate method was employed to measure plate wastes and consumption of the menus served. Nutrient analyses for the served and consumed menus were performed using CAN-PRO. The result of nutrient intake determined by self-reported food consumption demonstrated 74.2% of boys and 70.0% of the girls did not meet EAR(Estimated Average Requirement) for calcium. In addition, the data collection showed that 60.2% boys and 26.7% girls did not consume EAR for Vitamin B$_1$. Nutrient analyses of the served and consumed menus at school lunch were compared with 1/3 of the Dietary Reference Intakes(DRIs) for this age group. The served menus did not meet 1/3 of the Recommended Intake(RI) for calcium, iron, and vitamin B$_2$. In contrast, the menu provided to students exceeded almost five times(490%) more than the sodium needed for 1/3 of the Adequate Intake(AI). Considering the amount of the students' plate waste, intake of vitamin A and vitamin C were below 1/3 of the RI, and calcium, iron, and vitamin B$_2$ intake were also reduced. Students' sodium consumption still exceeded 1/3 of the AI at 340.0%.

The purpose of this study was to investigate the differences is food consumption behavior based on singles' food-related lifestyle. A survey was conducted with singles(age 25~54) in the Seoul metropolitan area. Out of 2,051 questionnaires distributed, 300 were analyzed(15.21% response rate). The data was analyzed using SPSS windows(ver. 17.0). Singles' food-related lifestyles were categorized into three groups. In addition, the respondents were divided into three groups by cluster analysis: convenience oriented group, wellbeing dining-out oriented group, and uninvolved group. The food consumption behavior of each group was significantly different in terms of considerations of food consumption, preference of food product types, and breakfast types. The convenience oriented group prefered to buy ready to cook food, ready to heat food and ready to eat food. Moreover, they often eat instant food. The wellbeing dining-out group is more interested in foods and their health than other groups. The uninvolved group was not concerned about food. This study suggests that the food industry the characteristics of singles' needs to be analyzed more systematically. By analyzing the characteristics of singles', the food industry can use the data to establish a marketing strategy for them.

The current exploratory study attempted to investigate the influence of environment-friendly agricultural products(EAPs) perception on EAPs consumption behavior. The survey was conducted to parents of elementary school in Chung-buk area by the help of homeroom teachers of each school. Out of 500 questionnaires administered, a total of 305 completed questionnaires were returned, yielding a response rate of 61%. Regarding buying behavior, 89.6% of respondents have ever bought EAPs, among them, 52.9% usually bought in a mart. The reason to buy EAPs was mostly safety(57.6%), nutrition & health(30.4%), and quality(7.0%). The 11 items representing the attitude and knowledge were analyzed, resulting in three distinct dimensions-'attitude', 'knowledge', and 'concern'. The knowledge level of EAPs was slightly higher than medium. Concerning the influence of EAPs perception on EAPs consumption behavior, the more having high knowledge and attitude level on EAPs, the more lead to the EAPs consumption behavior. This implicit the importance of education to enhance the knowledge level and positive attitude towards EAPs.

This study investigates the exercise-physiological changes in stages through the movement of the automatic stepper and to analyze the usefulness of the automatic stepper. For 18 male university students, out of 10 levels, 5 level and 10 level of automatic stepper exercise were performed. At each 10, 20, 30 minutes during exercise, 5 and 10 minutes after exercise stop the subjects were examined to analyze the changes in energy consumption after minutes, respiratory exchange rate, heart rate, oxygen consumption per body weight, METs, cumulative energy consumption, and lactic acid to verify the usefulness of the automatic stepper. The mean and standard deviation were calculated using the SPSS, and one-way ANOVA with repeated measure was performed to verify the difference in the mean between time periods. The LSD method was used for the post-hoc test, and the significance level was set to α = .05. There were no significant changes in both 5 and 10 level, but the cumulative energy consumption over time increased significantly. In addition, as a low-intensity exercise intensity is shown, a low increase in lactic acid indicated a safe exercise level. In future studies, in-depth studies of various variables through regular exercise programs are needed for those who need safe exercise.

This study attempts to analyse the food consumption expenditure patterns of wage-Earner's Households n terms of the changes in income during 1975∼1985. For the purpose of these time-series analysis and cross-section analysis, household survey data 'Annual Report on the Family Income and Expenditure Survey'- was used. The main results can be summarized as follows : 1. The proportion of the food expenditures has decreased with the increased of income in the city families during 1975∼1985. The Income-Elasticity and limit spending habits has decreased with the increase of income in the city families during 1975∼1985. 2. Analyzing the structure of the food consumption of each income class, the results reflected the Engel's law. That is to say, the higher income was, the more absolute expense for food was, but the rate of it was.

Prolonged Russia-Ukraine war, and unstable situation of supply and demand of global crops including the COVID-19 pandemic have raised awareness regarding food crisis, and in addition to this situation, export restriction measures imposed by some countries have accelerated the rise in the prices. Since the Republic of Korea depends annual crop consumption (21.32 million tons) mostly on the imports (food self-sufficiency rate in 2020 was 45.8%, crop self-sufficiency rate was 20.2%), our main task is to stably secure food. Now we need to put focus on building capacity to secure stable food supply, and actively manage and respond to risks. To overcome this condition, the Korean government set robust food sovereignty as its policy task, and has been focusing on the policy capacity by providing financial and policy support in parallel. We need to implement mid- to long-term measures to strengthen food security as well as to ensure domestic price stability. While increasing the domestic capacity to supply food in the mid- to long-term perspective, we are implementing projects to bring in crops which are inevitable to be imported by private companies. Specifically, we are making efforts to expand infrastructure for the public reserve and domestic production of wheat and beans which have low self-sufficiency rate, and to secure food sovereignty by providing support to secure global crop supply chain to private companies. The Ministry of Agriculture, Food and Rural Affairs plans to set a target for food self-sufficiency rate and prepare a policy to strengthen mid- to long-term food security by establishing a task force to strengthen mid- to long-term food security in the Ministry. Especially, although wheat is the second staple food, domestic wheat production and the foundation for the industry is poor. Compared to the wheat imports, domestic production of wheat is 30 thousand tons (self-sufficiency rate of 1%), leading to a vulnerable status against internal and external shocks. Through the establishment of the Wheat Industry Promotion Act (Feb. 2020) and the First Master Plan for Wheat Industry Promotion (Nov. 2020), the Korean government has developed a policy basis, and has been providing financial support in overall across the production, distribution and consumption process. In addition, the government established a production complex for Korean wheat and beans in order to supply affordable government-supplied commodities, provide education and consulting services, and create a high-quality stable production system, including facilities and equipment. We are also continuing to increase the public reserve for wheat and beans with the purpose of stable supply and demand as well as food security. The Korean government will establish and implement mid- to long-term measures to strengthen the foundation for domestic production across production, distribution and consumption process, and to stably secure global supply chain including through diversified import channels.

This study was to investigate the changes in dietary practices, reasons for making dietary changes, current food consumption patterns, and eating habits. Data were collected from 515 parents whose children were attending an elementary school and a middle school in Kimcheon. Among the twenty food groups studied, subjects reported eating more fruit, vegetables, lower-fat meats, high-fat meats, reduced/skim milk, and eggs and less sugar, fats, rice, salt, potato/sweet potato, and chicken. The changes in dietary practices except high-fat meats and salt were significantly different between sex, age, education level, income level, or BMI groups. The primary reason for making dietary changes was 'concerned about family's health'. The average rate of never eating breakfast or less than 2 times per week was found to be 23.2% with a greater rate in younger age group. The rate of breakfast skipping was found to vary between different age and education groups. The regularity of mealtime and overeating practices were significantly different between age groups. Eating out practices were found to vary between different age, education, and income groups. People at younger age group in Kimcheon should be targeted for nutrition education about eating habits. These findings are applicable at the planning and implementation stages of various nutritional improvement projects.

Farm households consumption pattern from 1960 to 1968 was analized as follows. First, the influence of the price on the consumption pattern was observed by year for 9 years. Second, the influence of farm households and by size of the consmption pattern was analized by year for whole household and by size of the arable land. Third, the present status and problems of farm families consumption pattern was attempted to be found out compared with the pattern of all families of Seoul. Forth, the pattern of food expenditure which has the largest proportion in the living expenditure was analized. Following results and conclusions are obtained from the above analysis.1. The average nominal increase rate of all farm households has been increased gradually for 9 years, mostly due to the rise in household goods prices paid by farmers. 2. The living expenditure varies with the price and the disposal income, The influence of the latter is greater than that of the former. 3. The Engel's Coefficient of farmers. the average of which was 54.9%, recently tends to decrease gradually. The larger is the size of arable land, the lower is the Coefficient of farm households. But the Coefficient of farm households is higher than that of city families. 4. In general the proportion of food expenditure has a great influence on the consumption pattern, The average percentage of miscellaneous expenditure is 23.9% and it is next to food expenditure. The relationship between them is going reversely. Housing expenditure has usually the constant proportion. But the difference of the proportion between farm households (4.0%) and city families (17.1%) is considerable. Clothing expenditure and fuel and light expenditure have small variations. The former tends to increase with the income, and the latter tends to decrease with it or is constant. 5. Considering the food expenditure pattern, the average percentage (78.4%)of staple food of farm household is remarkably high compared with Seoul (48.3%) and other cities (54.0%). The decrease of the percentage of staple food expenditure in farm households is not so much as cities. 6. The propertion of the staple food expenditure of Farm families don't have so much differences by the size of arable land. But the rice proportion of staple foods has the tendency to increase with the income level. Subsidery food expenditure doesn't increase by year and by size of the land, while the consumption of meat and manufactured foods tends to increase with size of the land. But even big farm households don't reach to the level of cities in consumption of them. 7. Food consumption pattern may be influenced by the factors such as the knowledge of wife about nutrition, customs, consumption habits, and so on. The difference between farm households and city families in food consumption pattern is inferred from the above factors. Presently, the increasing income of the people promote the consumption of all items of living expenditure both in cities and farm households. But the Engel's Coeffcient and the proportion of the staple food expenditure is expected to decrease in farm households more than in cities.

The purpose of this paper is illuminating positively the perception and compliance rate of local food principles in Korea. The results are as follows. First, in terms of the perception rate, social trust and local production/consumption are the most important components rather than eco-friendliness. This means the importance of both spatial and social aspects of local food concept. Second, in terms of the compliance rate, social trust and shortened food chain are well complied, rather than eco-friendliness and shortened food miles. Third, in terms of the difference between perception and compliance rate, the social aspects such as eco-friendliness, social trust, and shortened food chain has shown relatively smaller difference than the spatial aspects such as shortened food miles and local production/consumption.
