Among the noise evaluation units, the unit that meets the military helicopter noise evaluation is analyzed and selected to scientifically and reasonably resolve the conflict between residents in the neighboring area and the aviation battalion. Helicopter noise is one of the important problems causing pollution in various pollution problems in the area around the aircraft battalion. The rational and planned process of aircraft battalions will be a way to address aircraft noise pollution.

The objectives of the study were to examine food waste generation and reduction efforts at home, and to identify factors affecting the intention to reduce food waste. A total of 3,321 food buyer responses were used from the 2022 Consumer Behavior Survey for Food of the Korea Rural Economic Institute. Statistical methods for a complex sample were applied by using a SPSS program (ver. 26.0). The average daily food waste generation per household significantly differed by the main food purchaser’s age and household size. Plate waste and food waste from preparation were the main types of food waste. A multiple regression analysis revealed that intention to reduce food waste was influenced by the main types of food waste, the average daily amount of food waste, the perceived amount of food waste, and the perceived importance of food waste reduction after adjusting for the age of the main food purchaser and household size. Since the amount of food waste was affected by a series of food behaviors as well as consumer’s intention to reduce waste, empirical research on the types and amounts of food waste generated in Korean households and qualitative research on behaviors and attitude affecting food waste are needed.

This study examined the intake status and the factors affecting intake of functional foods using the data from Consumer Behavior Survey for Food by the Korea Rural Economic Institute. Among the total respondents, 80.4% took functional foods, and the number of respondents who took two types of functional foods was the highest. The main reason for taking functional foods was to prevent disease, and the main places of purchase of functional foods were off-line large supermarkets, on-line shopping malls, and pharmacies. Compared to a year ago, the percentage of increase in functional food purchases this year was higher than the percentage of decrease. The most common reasons for not taking functional foods were ‘not feeling the need’ and ‘not trusting the quality’. As a result of conducting a complex samples logistic regression analysis to identify the factors affecting the intake of functional foods, gender, age, marital status, illness state, alcohol drinking, and convenience-seeking type among dietary lifestyles were significant.

This study examined differences in breakfast habits, mental health, and the prevalence of allergic diseases among 9,549 adolescents from father-headed and mother-headed families, using raw data from the 2017~2019 Korea Youth Risk Behavior Web-Based Survey. Of the total participants, 44.6% came from father-headed families, while 55.4% were from mother-headed families. Single-parent adolescents showed the highest likelihood of eating breakfast every day of the week (24.5%), but they also had a significant tendency to skip breakfast entirely (24.3%). There was no significant difference in breakfast frequency between those from father-headed and mother-headed families. The perception of stress and subjective health status did not differ significantly between adolescents from the two types of families, although subjective health status did show significant differences among boys. Depressive experiences were notably higher in adolescents from mother-headed families (33.0%) compared to those from father-headed families (30.8%). Additionally, the prevalence of atopic dermatitis and allergic rhinitis was significantly greater in adolescents from mother-headed families (24.2% and 32.1%, respectively) than in those from father-headed families (21.1% and 26.5%, respectively). These results indicate the need for tailored nutrition and health guidance programs for adolescents from single-parent families to support the role of the absent parent.

This study compared the dietary perceptions, food labeling behaviors, and purchasing patterns of vegetarians and nonvegetarians. The data from 5,811 adults aged ≥19 years who participated in the 2023 Consumer Behavior Survey for Food were analyzed. The participants were divided into vegetarians and non-vegetarians according to their dietary practices. Vegetarians were further divided into strict, semi, and occasional vegetarians. Non-vegetarians regularly consumed plantand animal-based foods without dietary restrictions. Vegetarians comprised 15.4% of the participants, and health (50.4%) was the primary motivation for adopting a vegetarian lifestyle. Compared to non-vegetarians, vegetarians prioritized their rights and responsibilities as citizens and identified a vegetable-centered diet as the most crucial factor for health. Vegetarians showed greater interest and trust in food labeling than non-vegetarians. Vegetarians selected a wider variety of food and had different purchasing motivations when purchasing eco-friendly foods than non-vegetarians. Vegetarians exhibited higher purchase frequencies across all categories than non-vegetarians and had different reasons for purchasing convenience foods. These findings highlight the diversity of vegetarian dietary motivations and behaviors, emphasizing the need for tailored dietary policies and education.

This study aims to identify crisis signs in small and medium enterprise (SME)-concentrated regions and establish measures to prevent economic recession and normalize regional economies through proactive responses. To achieve this, we investigated and analyzed the crisis status and outlook of companies located in Jeonbuk, their detailed management conditions, management issues by industry, difficulties in business operations, and policy demands. Out of 4,144 SMEs in Jeonbuk's concentrated areas, 270 companies responded to the survey. The results showed that 60% of the responding companies perceived their current management situation as being in a state of crisis. However, the outlook for the next quarter and the following year is expected to improve. Notably, compared to manufacturing companies, non-manufacturing firms responded that their crisis situation in the next quarter would not improve and expected the crisis to persist. In terms of detailed business conditions, regardless of the distinction between manufacturing and non-manufacturing sectors, all aspects of the survey, including domestic sales, export sales, operating profit, financial status, and the number of employees, indicated better prospects for the next quarter and the following year compared to the current quarter. The study's findings suggest that companies in SME-concentrated areas of Jeonbuk are relatively accurate in recognizing the crisis situation of their own businesses and operating markets. Additionally, the companies responded that crisis monitoring is necessary. Differences in difficulties faced by the manufacturing and non-manufacturing sectors imply the need for industry-specific financial support programs. Based on the survey results, we propose financial support projects tailored to the manufacturing and non-manufacturing sectors, considering the degree of market competition. For more precise research, future studies will involve extracting larger samples and conducting a detailed analysis by subdividing manufacturing sectors (e.g., food, metal) and non-manufacturing sectors (e.g., agriculture, design).

This study analyzed the status of agrifood consumer competencies and the factors influencing them to provide useful information to improve the quality of life by strengthening the agrifood consumer competencies. The raw data of the 2022 Consumer Behavior Survey for Food collected by the Korea Rural Economic Research Institute were used. The data from 3,321 responses were used for the final analysis. Among the competencies, the average score of the cognitive and practical competencies were 3.543 and 3.459 points, respectively. In addition, the average scores of the specific areas within cognitive competency were 3.587 points for dietary competency, 3.557 points for civic competency, and 3.489 points for purchasing competency. Within practical competency, the average scores of the specific areas were 3.569 points for dietary competency, 3.422 points for civic competency, and 3.392 points for purchasing competency. Gender, age, monthly household income, marital status, administrative district, interest in health, and interest in food safety issues were the significant factors affecting the specific areas within cognitive competency. On the other hand, gender, age, educational level, monthly household income, marital status, administrative district, interest in food safety issues, and each of the areas within cognitive competency had a significant impact on the specific areas of practical competency.

This study was performed to analyze dietary influences on the regulation of low-density lipoprotein cholesterol (LDL-C) in postmenopausal women using the 2019-2021 Korea National Health and Nutrition Examination Survey (KNHANES). A total of 1,724 women were classified into cardiovascular risk groups based on risk factors and differentiated into high LDLC and normal groups according to the target serum LDL-C levels. The risk group distribution was as follows: Very high-risk group (6%), high-risk group (49.4%), moderate-risk group (42.3%), and low-risk group (2.3%). The high LDL-C group demonstrated abdominal obesity and prediabetes, with their carbohydrate energy intake exceeding the Korean dietary guideline recommendations of 65%. Increased fat (OR 2.67, 95% CI; 1.19-6.02) and cholesterol (OR 2.43, 95% CI; 1.02- 5.77) intake correlated with higher LDL-C risk. The high LDL-C group showed elevated saturated fat and reduced polyunsaturated fat consumption (p for trend <0.001). Thus, to regulate the LDL cholesterol levels in postmenopausal women, they maintain an appropriate weight in addition to managing abdominal obesity and continuously monitoring blood sugar levels. Furthermore, it is important to limit the intake of high saturated fat meats and consume sufficient protein from sources such as beans, fish, and eggs, which contain healthy unsaturated fats.

The domestic swine industry is currently facing a threat due to the recent increase in pork imports. This study aims to determine what factors influence consumers' intention to consume imported pork and suggest measures to support the domestic pork industry. To achieve this, we analyzed data from the Korea Rural Economic Institute's Food Consumption Behavior Survey using a binary logistic regression model. The results revealed that a higher intention to consume imported pork is linked to a higher intention to consume imported rice, purchasing meat online, frequent purchases of HMR, and procuring U.S. beef, especially among urban residents. On the other hand, a lower intention to consume imported pork is associated with a higher awareness of animal welfare certification, frequently dining out, and older age. Based on these findings, we propose the following response measures for the domestic swine industry: implementing educational programs, marketing, and advertising specifically targeting urban residents to improve their perception of domestic agricultural products; enhancing price competitiveness through distribution optimization; and developing policies to promote the use of domestic pork as an ingredient in processed foods.

This study examined dietary habits and mental health according to generalized anxiety disorders (GAD) and caffeine consumption in adolescents. The data were collected from the 18th Korea Youth Risk Behavior Survey with a sample of 51,850 students. The proportion of students in the GAD High-Risk · Caffeine consumption group (GHRCC) who consumed sweet drinks (p< .001), fast food (p< .001), and midnight meals (p< .001) every day was 15.6, 21.9, and 22.4%, respectively. These proportions were higher than those of students who consumed sweet drinks, fast food, and midnight meals 1-2 times a week, 3-4 times a week, or not at all. In addition, the proportions of GHRCC among students who responded “yes” to experiencing sadness and despair (p< .001), suicidal thoughts (p< .001), suicide plans (p< .001), suicide attempts (p< .001), and loneliness (p< .001) were higher than students who responded “no.” The GAD High-Risk group (GHR) had higher odds with the consumption of midnight meals (OR: 2.51, 95% CI: 2.10-2.99), caffeine consumption (OR: 2.46, 95% CI: 2.21-2.74), and fast food (OR: 2.11, 95% CI: 1.75-2.55) than GAD Low-Risk group. Based on the above results, the risk of GHR was higher among students who consumed midnight meals, caffeine, and fast food daily than those who did not.
