Since delivery food has become a new dietary culture, this study examines consumer awareness through big data analysis. We present the direction of delivery food for healthy eating culture and identify the current state of consumer awareness. Resources for big data analysis were mainly articles written by consumers on various websites; the collection period was divided into before and after COVID-19. Results of the big data analysis revealed that before COVID-19, delivery food was recognized as a limited product as a meal concept, but after COVID-19, it was recognized as a new shopping list and a new product for home parties. This study concludes by suggesting a new direction for healthy eating culture.

In this study, scones were prepared using Cordyceps powder, described as ‘immortal life’. Cordyceps powder was prepared in 0%, 2%, 4%, 6%, and 8% ratios, and salinity, color, texture, and antioxidant properties were analyzed. The salinity of Cordyceps scones did not show a difference according to the amount of Cordyceps powder added (p=0.364), and the a-, b-values increased significantly (p<0.001). In the case of texture, there was no significant difference in the amount of Cordyceps added. Flavonoids increased significantly as the amount of Cordyceps powder increased (p<0.001). ABTS-radical scavenging capacity increased significantly as the amount of Cordyceps powder increased (p<0.001). Through this study, the antioxidant properties of Cordyceps scones were confirmed.

An increasing trend embracing the 2030 generation mindset through the new word ‘newtro’, which means reinterpreting the past and selling it in the present, has been gaining traction. The 2030 generation who seek new experiences and desserts is growing. The unique dessert market is expected to continue to grow in the future. Thus, this study devised a pine needle madeleine. Madeleines were made by varying the proportions of pine needle powder added to 0%, 1%, 3%, 5%, and 7%, and specific gravity, moisture, color, physical properties, and antioxidant properties were measured. The L-value decreased significantly (p<0.001) as the amount of pine needle powder added increased, and the a-value increased (p<0.001). The total polyphenol content, DPPH, and ABTS gradually increased significantly (p<0.001). Through this study, it was possible to confirm the quality and characteristics of madeleines using pine needle powder, which has excellent antioxidant properties, and it will become basic data for the development of various desserts using pine needle powder.

As cholesterol intake increases, the prevalence of hypercholesterolemia is also increasing. With increasing food selection considering health, consumption of functional foods that can help health is also expected to increase. Ginger is rich in minerals (such as potassium and magnesium) and antioxidants. Antioxidants have been shown to be effective in lowering blood cholesterol levels. Therefore, we would like to produce madeleines helpful for hypercholesterolemia by adding ginger syrup to madeleines recently consumed as desserts. In this study, the quality and characteristics were analyzed after making madeleine by adding ginger syrup at 0%, 5%, 10%, 15%, and 20%. Baking loss was significantly reduced as the addition amount increased (p<0.001). The pH value decreased as the addition amount increased except for the 5% added group (p<0.001). The b value of the chromaticity showed a significant increase from the 5% addition group (p<0.001). Regarding textures, hardness (p=0.006), gumminess (p=0.001), and chewiness (p=0.001) all decreased as the addition amount increased. Regarding antioxidant activity, polyphenol, DPPH, and ABTS values were significantly increased as addition amount increased (p<0.001). Consequently, Madeleine using ginger syrup rich in antioxidants is expected to help health.

In this study, we developed a healthy snack using dried shrimp powder which is rich in calcium to help prevent bone disease. Different types of yanggaeng were prepared with varying ratios of dried shrimp powder; 1%, 3%, 5%, and 7%. Moisture content, color value, texture properties, and mineral concentration were measured. The L, a, and b chromaticity values showed significant differences in the 5% addition group (p<0.001). The texture properties, hardness, and adhesion decreased significantly as the amount of shrimp powder increased (p<0.001), while chewiness and elasticity significantly increased as the amount increased (p<0.001). Calcium and potassium increased significantly as the amount of shrimp powder increased (p<0.001).

This study tried to develop Jinmal dasik using pine nuts leaf powder with antibacterial and antioxidant properties. After preparing the Jinmal dasik in proportions of 0%, 2%, 4%, 6%, and 8% by varying the ratio of pine needle powder, the moisture, color, physical properties, antioxidant properties and sensory quality were measured. Except for the 8% Jinmal dasik, the L value of chromaticity significantly decreased as the amount of pine needle powder increased (p<0.001). In addition, the value significantly decreased with increased density (p<0.001). Based on our physical properties evaluation results, the hardness, cohesiveness, and elasticity decreased significantly as the amount of pine needle powder increased (p<0.001), but adhesion and chewiness increased significantly with an increase in the amount of pine needle powder (p<0.001). Total polyphenol content was significantly increased except for the 8% Jinmal dasik (p<0.001). DPPH and ABTS also increased significantly as the amount of pine needle powder increased (p<0.001). Our sensory evaluation, showed the 2% Jinmal dasik to have the highest degree of preference, however, there was no significant difference among the proportion groups (p=0.053).

In this study, data from the 7th (2016~2018) and 8th (2019) Korea National Health and Nutrition Examination Surveys were used, which included 5,325 subjects. Health behavior, dietary and nutrient intake status, physical measurement and biochemical characteristics, and risk factors for elderly related chronic diseases were classified and analyzed according to the changing composition of single households and other households in the current society. As a result, the ratio of current smokers and drinkers in young adult single households, walking less than 30 minutes per day, subjective health status was poor, breakfast rate less than three times per week, eating out frequency more than once a day, lipid intake ratio to total calories, saturation fatty acid intake were significantly higher. In addition, waist circumference, and diastolic blood pressure were significantly higher. However, dietary fiber intake level was significantly lower. The results for hypertension, which is the representative chronic disease that causes old age-related chronic diseases, were significantly higher in single households (ORs=1.400 (95% CI: 1.095, 1.791), p=0.007). Although young adults may not have showed particularly serious health problems yet, education is believed as important to recognize and prevent age-related disease risk factors.

This study compared the lifestyle patterns, dietary patterns, and health care practices of Korean middle-aged people by household type, and ultimately analyzed their relationship with different risk factors for the prevalence and severity of metabolic syndrome. We analyzed the data from 4,755 subjects who were from 40 to 64 years old, and gathered our sample from participants of the Korea National Health and Nutrition Examination Survey from 2013 to 2015. Our results showed that single-person households had lower economic income levels, lower subjective health statuses, and higher levels of food instability than households with two or more individuals. The incidence of metabolic syndrome was 1.64 times higher in single-person households than in households with two or more individuals. After adjusting for potential confounding factors (sex, age, education, household income, smoking status, health status, and dietary factors), single-person households showed 1.75 times higher hypertriglyceridemia ORs than non-single-person households. In the conclusion of our study, we suggest that middle-aged people in single-person households may be at greater risk for metabolic syndrome and hypertriglyceridemia.

The objective of this study was to produce a nutrient delivery system (NDS) using sialic acid extracted from edible bird’s nest (EBN), which improves brain function in patients with Alzheimer’s disease and Parkinson’s disease, by affinity bead technology (ABT). The inhibitory activity of acetylcholinesterase (AChE) and pyramidal cells in the dentate gyrus of the hippocampus were analyzed to investigate the effect of a sialic acid NDS on Alzheimer’s disease. Also, the effect of a sialic acid NDS on Parkinson’s disease was evaluated by rota-rod test and pole test in an animal model. Among the groups treated with donepezil, EBN, and sialic acid NDS, the AChE activity was the lowest in the sialic acid NDS-treated group. The results of the hippocampus analysis of the rat model confirmed that the sialic acid NDS inhibited amyloid-beta accumulation depending upon the concentration. Also, the sialic acid NDS group showed more improvement in motor deterioration than the1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)- induced group in both the rota-rod test and pole test. Therefore, the sialic acid NDS had an effect of protecting not only Alzheimer’s disease by inhibiting AChE and amyloid-beta accumulation, but Parkinson’s disease by preventing neurotoxicity induced by MPTP.

본 논문은 학부 외국인 유학생을 위한 한국 한자어 교육 방안을 원격 수업 설계 및 운영 사례를 중심으로 살펴보았다. 대학에서 원격 수업의 중요성과 비중이 갑작스레 커진 상황에서, 대면 수업에 준하는 수업 효율을 유지할 수 있는 방안을 찾는 일은 중요한 과제 가운데 하나라고 할 수 있다. 이 과정에서 ‘외국인 유학생 대상 한자(漢字) 수업’이라는 변수를 고려하여 실제 대학 강의 현장에서 수업 설계와 운영에 반영하고자 하였다. 원격 수업은 그 특성상 대면 수업이 가지는 현장성·동시성·양방향성·상호교감성을 완벽하게 재현해내기는 어렵다. 하지만 주어진 환경 속에서 대면 수업의 효율을 유지하고 원격 수업의 장점을 극대화하기 위한 노력이 필요하다는 점을 언급하였다. 코로나 19 이후 빠르게 변화하고 있는 강의 환경을 고려할 때, 본 연구를 하나의 사례로 삼아 후속 논의가 지속되기를 기대한다.

The purpose of this study was to investigate the comparison of nutrient intake and metabolic syndrome between single person households and non-single person households in elderly subjects. We analyzed data from 2,903 subjects ≥ age 65 who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2013~2015. As a result, single-person households had lower income and economic ability, overall nutrient intake was deteriorated, and the proportion of high-carbohydrate intake was high, compared to non-single person households. After adjusting for potential confounders (sex, age, education, household income, economic activity, smoking status, alcohol consumption, walking frequency, health status, depression status, and dietary factors), the singleperson household showed a tendency of 1.22-fold higher ORs of metabolic syndrome and 1.3-fold higher ORs of hypertriglyceridemia than the non-single-person household. We suggest that the single-person household may be associated with increased prevalence of metabolic syndrome and hypertriglyceridemia in the elderly subjects.

Red Chinese cabbage is rich in anthocyanins, with beneficial effects on anti-obesity and lipid profiles. The purpose of this study was to examine the anti-obesity effects of red Chinese cabbage. Four-weeks old Spague-Dawley male rats were divided into four groups for six weeks as follow: Normal Diet (ND), High Fat Diet (HFD), HFD + Red Chinese Cabbage Diet (RCD), HFD + Red Chinese Cabbage Juice (RCJD). After six weeks, the liver weight was significantly higher in the HFD group than in the other groups, and the RCD and RCJD groups showed similar values to the ND group. The epididymal fats were significantly higher in all high fat diets (HFD, RCD, RCJD) than in the ND group and there was statistical significance in the post-tests when comparing the RCD and RCJD groups with the HFD group. Triglycerides significantly decreased in the RCD group. In conclusion, red Chinese cabbage is rich in anthocyanins, with beneficial effects on organ weight and lipid profiles.

Since the discovery of the first artificial synthetic plastic, bakelite, polymer materials have been recognized as one of the most innovative fields of research. The plastic debris that is being piled up on the earth (called abandoned plastic litters) is now being observed everywhere on Earth, becoming an increasingly serious environmental threat. The term 'microplastics', created in 2004, now refers to plastic particles that are smaller than 5 mm, including all nano-sized plastic particles. However, there is no legal regulation, and there is still a lack of comprehensive definitions that practically include microplastic size standards. In this study, we will refer to “microplastics” as the English name, and look at how to identify these microplastics and propose new definitions that focus on their size. This study is expected to contribute to the domestic consensus on scientific definitions of microplastics.
