목적: 건성안은 스트레스에 의해 영향을 받을 수 있는 대표적인 안과 질환이다. 본 연구는 제8기 국민건강영양조사 (2019–2021) 원시자료를 활용하여, 직업에 의한 스트레스와 건성안 간의 관련성을 분석하고자 하였다. 방법 : 국민건강영양조사 제8기 자료 중 건성안 진단 유무와 스트레스 인지 정도에 응답한 3,781명을 대상으로, 성별, 연령, 학력 등의 일반적 특성과 건성안 진단 유무, 스트레스 인지 정도, 직업군별 건성안 유병률 간의 관계를 분석하였다. 통계적으로 p<0.050을 유의수준으로 설정하였다. 결과 : 여성에서 남성보다 건성안 유병률이 높았으며, 젊은 연령층과 고학력자에게서 유병률이 유의하게 높았 다. 스트레스 인지 수준이 높을수록 건성안 발생률도 증가하였고, 직업군별로도 유의한 차이를 보였다. 결론 : 직업에 의한 스트레스는 건성안 유병률 증가와 통계적으로 유의한 관련이 있었다. 특히 스트레스 수준이 높은 직업군에서 건성안 발생률이 높았으며, 이에 따라 직업환경 개선 및 예방 대책 마련의 필요성이 확인되었다.

목적 : 본 연구는 2022년도 국민건강영양조사(KNHANES) 데이터를 활용하여 시력 수준과 정신건강 지표(우울, 불안) 간의 연관성을 분석하고자 하였다. 방법 : 2022년도 국민건강영양조사 원시자료 중 시력검진 및 정신건강 설문(PHQ-9, GAD-7)에 모두 응답한 519명의 성인을 최종 분석 대상으로 포함하였다. 시력 상태는 정상, 경도 시력손상, 저시력으로 구분하였으며, 복 합표본 로지스틱 회귀분석을 통해 시력과 정신건강 지표 간의 연관성을 분석하였다. 결과 : 경도 시력 손상은 중등도 이상 불안 고위험군에 속할 가능성이 정상 시력군에 비해 약 9.5배 높았으며 (OR=9.54, 95% CI: 2.01–45.25, p=0.005), 저시력군의 경우 우울 위험이 정상군 대비 약 4.3배(OR = 4.27, 95% CI: 0.85–21.56) 증가하는 경향을 보였으나 통계적으로 유의하지 않았다(p=0.081). 결론 : 시력 저하는 단순한 감각 기능의 저하를 넘어 정신건강에 유의미한 영향을 미치는 요인으로 작용할 수 있으며, 특히 경도 시력 손상군은 제도적 지원의 사각지대에 놓여 있어 더 큰 심리적 부담을 겪을 가능성이 높다. 향후 공중보건 정책에서는 시력 저하 단계별 특성을 고려한 조기 선별 및 정신건강 중재가 필요하다.

메타버스는 현실 세계가 확장된 가상 세계를 말하며, 상호 작용을 위한 교수·학습 플랫폼으로 수업에 활용되고 있다. 이는 현실 세계와 가상 세계가 적절하게 융합된 학습자 중심의 교육을 가능하게 하고 학습의 몰입감을 제공한다. 현재 메타버스를 적용한 해기 교 육 연구 사례가 드물며, 본 연구는 이러한 메타버스의 장점을 해기 교육에 적용했을 때 나타나는 효과를 학습 흥미도와 참여도, 학업 성 취도, 현장 실무 능력 측면에 적용하기 위함이다. 이에 해기 교육에 활용할 실감형 메타버스 해기 교육 프로그램을 제작하여 실제 B고등 학교에서 해기 교육을 수료 중인 기관과 학생 74명을 대상으로 수업을 실시하였다. 연구 결과는 학습 흥미도와 참여도, 학업 성취도, 현장 실무 능력 영역이 모두 향상되었으며, 특히 학업 성취도가 낮은 학생들의 성취도가 향상되어 전체적인 학업 성취도가 높아지는 효과를 확인하였다.

목적 : COVID-19 팬데믹 기간 동안 사회적 거리두기와 비대면 활동 증가로 인해 생활습관이 크게 변화하였다. 본 연구는 근거리 작업시간, 수면시간, 스트레스 수준의 변화가 비정시(근시, 원시, 난시) 발생에 미치는 영향을 분 석하고자 하였다. 방법 : 본 연구는 질병관리청 국민건강영양조사 제8기(2019~2021년도) 조사 중 2020년에 참여한 대상자들 중 만 40세 이상인 성인들을 대상으로 수행된 단면 연구이다. 연구 대상자는 안검진을 받은 성인 중 안과 질환이 없는 2,564명을 포함하였다. 굴절 이상은 등가구면굴절력을 기준으로 하였다. 결과 : 근거리 작업시간이 하루 4시간 이상인 그룹에서 근시 유병률이 유의하게 증가하였다. 반면, 1시간 이하 의 근거리 작업을 수행하는 그룹에서는 원시 유병률이 높았다(p<0.0001). 수면시간이 6~8시간인 그룹에서 근시 유병률이 가장 높았으며, 원시는 6시간 미만 그룹에서 높았다(p=0.0082). 스트레스 수준이 높은 그룹에서 근시 유 병률이 유의하게 증가하는 경향을 보였으나, 다중 로지스틱 회귀분석에서는 근거리 작업시간이 짧은 그룹에서 난시 유병률이 더 높은 경향을 보였으며(p<0.0001), 수면시간과 스트레스의 영향은 통계적으로 유의하지 않았다. 결론 : 본 연구 결과, 근거리 작업시간 증가가 근시 발생에 가장 큰 영향을 미치는 요인임이 확인되었으며, 수면 패턴과 스트레스 또한 비정시와 연관성을 가질 수 있음을 시사하였다. 이는 COVID-19 팬데믹과 같은 환경적 변 화가 시력 건강에 미치는 영향을 이해하고, 근시 예방 및 관리 전략을 수립하는 데 기여할 수 있다.

I would like to suggest a solution to the problem of aircraft battalion helicopter noise complaints. 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.
