        This study examined the nutrient intake of Korean adults by considering the lunch type, categorized as home meals (HM), eating out (EO), and institutional meals (IM). Data was obtained from the 2019 Korea National Health and Nutrition Examination Survey (KNHANES). Totally, 3,786 adults (1,643 men, and 2,143 women) aged between 19-64 years were included in the study. Subjects with daily energy intake of less than 500 kcal or over 5,000 kcal, and those who skipped lunch, were excluded. The percentage of subjects in the HM, EO, and IM were 31.9, 53.6, and 14.4%, respectively. The daily energy intakes of the HM, EO, and IM groups were determined to be 2,185, 2,360, and 2,339 kcal, respectively, in men, and 1,622, 1,731, and 1,741 kcal, respectively, in women. Among the three groups, men in the EO group had more intake of fat, saturated fat, cholesterol, sodium, and riboflavin, and less dietary fiber, and whereas women consumed more fat and less dietary fiber and potassium. In the IM group, the men consumed more dietary fiber, potassium, and thiamine, whereas consumption of carbohydrate, unsaturated fatty acid, sodium, potassium, and thiamine was more in women. Energy contributions of carbohydrate, protein, and fat were all within the AMDR (acceptable macronutrient distribution ranges) for all lunch types, except for the percent of energy provided from saturated fat in EO (7.4% in men, and 8.2% in women). Our results indicate that the dietary habit of frequently eating out increases the fat intake, thereby resulting in increased health risks for adults. Thus, implementation of a nutritional education program to encourage balanced dietary habits is required to improve the nutritional status of individuals eating out.

        This study was conducted to investigate the intake status of beverages and water in Korean adults using data from the 8th National Health and Nutrition Examination Survey. The ‘total water’ intake was 2,250.6 g for men and 1,871.2 g for women. Men and women consumed an average of 314.9 g of ‘total beverages’, of which ‘coffee’ was the largest at 107.5 g, followed by ‘others’(65.4 g), ‘milk’ (44.8 g), ‘soda’ (44.1 g), ‘teas’ (20.9 g), and ‘fruits and vegetables’ (18.5 g). The intake of ’plain water’ was 1,059.9 g, and the intake of ’water from food’ consumed was 547.3 g. The ‘total water’ intake decreased with increasing age in males and females (p<0.001). Both men and women showed a tendency toward increased ‘total water’ intake as income levels increased. ‘Plain water’ intake accounted for 51.4% of the ‘total water’ intake in males and females. The intake of all nutrients significantly increased from the Q1 group to the Q4 group by quartile ranges of total water intake. The results of this study showed that the intake of healthy water should be considered, and care and educational programs are needed, especially for older people, to ensure adequate water intake.

        This study aimed to assess the association between the weight status and dietary behavior of preschool children. The survey included 412 preschool children aged 2-5 years in 31 childcare facilities in Gwangju. General characteristics of children and their mothers, weight, height, feeding type, complementary feeding, food allergy, and dietary behavior of children based on the Nutrition Quotient for preschoolers (NQ-P) questionnaire were considered. Children were classified into 4 groups by weight status; underweight, normal, overweight, and obese, based on the 2017 Korean National Growth Charts. The percentage of children in the respective groups was 5.3, 70.9, 10.7, 13.1%. Weight status was not related to breast feeding duration nor the starting time of complementary feeding. The NQ-P scores of underweight, normal, overweight, and obese groups were 55.4, 60.0, 60.8, 60.0. Among the three factors covered by the NQ-P, ‘balance’ and ‘environment’ scores of the underweight group were lower than that of other groups. Underweight children consumed beans, fish, and white milk less frequently. The ‘moderation’ scores of the overweight/obese group were lower than those of the normal or obese groups. Obese children more frequently ate processed meat and fast foods. Proper nutrition education is thus needed for not only obese children but also underweight children based on their age, along with their parents, and caregivers.

        The purpose of this study was to investigate the current status of chronic diseases according to obesity in the elderly older than age 65 using data from the 7th Korea National Health and Nutrition Examination Survey (2016~2018). The subjects of the survey were 3,245 elderly older than age 65 who participated in the health survey and nutrition survey, 45.8% of the subjects were males and 54.2% of the subjects were female. 37.5% of all the elderly were obese, and the females (42.4%) were more obese than the males (31.8%) (p<0.001). Diabetes, hypertension, and hypertriglyceridemia had a similar prevalence of 24.6%, 63.0%, and 12.7% in males and females, respectively. Hypercholesterolemia was higher in the elderly females (44.2%) than in the elderly males (24.9%) (p<0.001). Through the logistic regression analysis, it was found that the prevalence of chronic diseases was higher in obesity than normal in elderly males and females (p<0.001). The total food intake increased from ‘under weight’ to ‘obesity’ in males (p<0.01) and females (p<0.001). In the case of the elderly males, the higher the degree of obesity, the higher the energy intake (p<0.05), and ‘pre-obesity’ consumed the most energy in elderly females. As a result of this study, the higher the obesity rate of the elderly, the higher the prevalence of chronic diseases.

        The purpose of this study was to investigate the quality attributes and importance that affects their satisfaction with respect to lunchboxes amongst children from low-income families in Korea. In case of 1-3rd-grade elementary school, 57.1% received lunch box through the community child center, while 45.2%, 68.5% and 80.7% of 4-6th-elementary school, middle school, and high school students received the lunch box from home, respectively. Typically, in 40.2% of all grades, the time to eat the meal was within 1~2 hours of delivery, and 34.0% consumed the lunch within 2~6 hours of delivery. With respect to intake of the contents of lunchboxes, 72.0% of the participants answered that they ate 80% of the lunchboxes delivered and 24.9% only ate 50% of the content of lunchboxes. The largest leftover were vegetables (26.9%), and the reason for leaving food was ‘do not like to eat (36.1%)’ followed by ‘no taste (32.6%)’. Regarding improvements in delivery lunchboxes, elementary school students selected ‘taste’, while middle school and high school students selected 'variety of menu'. The ‘nutrition (3.69 point)’ of the lunchboxes was the highest satisfaction and the ‘variety of menu (3.34 point)’ was the lowest. In all grades, ‘nutrition’ and ‘hygiene’ were considered to be important as quality attributes of the delivery lunchboxes, and satisfaction was also high. On the other hand, in the 1-3rd-grade elementary school, ‘variety of menu’ and ‘amount of side dish’ were important but satisfaction was low. The 4-6th-grade elementary school, middle school and high school students stated that ‘taste’and ‘variety of menu’ were important, but satisfaction was low.

        The aims of this study were to investigate usage status, menu preference, quality evaluation and satisfaction of homedelivered meal box for children from low-income families in Chungcheongbuk-do, Korea. A total of 320 children and their guardians who had received home-delivered meal boxes participated in 2015. A total of respondents (62.2%) were children and teenagers, and 37.8% were guardians. The 47.7% of children and 43.8% of guardians were using the home delivery service more than one year. Most of the children and guardians answered ‘eat almost’, ‘eat all meals’ served meal box, 75.3%, 81.8%, respectively. After receiving the meal box at home, 35.2% of children consumed meals within 1~2 hours, whereas 32.8% of the guardians were ate within 2~6 hours. It was founded that ‘throw away leftovers’ was the highest and followed ‘give it others’ in a way to treat leftovers. The results of preference survey on meats, seafood, showed that ‘chicken nugget’ (4.07) and ‘stir-fried fish cake with vegetable’ (3.63) were the highest points for children, whereas ‘grilled LA beef ribs’ (3.98) and ‘stir-fried anchovies’ (3.72) were the highest point for guardians. ‘Seasoned leaves marinated in soy sauce’ was the highest preference among vegetables and another dish for respondents. Frozen products were the most preferred types of meal boxes on the menu. In the quality evaluation of home-delivered meal box, although satisfaction with service and packaging of the meal box were high, the satisfaction of food quality was relatively low.

        오늘 날, 도시화와 인구 증가로 대도시 내에 대형 복합 건축물의 수가 증가하고 있다. 이러한 건축물은 그 규모와 복잡성으로 인해 작은 사고도 초대형 재난으로 확대될 수 있어 기존의 시설과는 다른 측면에서의 재난 관리가 필요한 실정이다. 발생 가능한 여러 유형의 재난 가운데 화재, 폭발 및 독극물 테러 등은 모두 유해물질에서 비롯되는 것으로, 유해물질의 발생을 감시하고 대응하여 그 피해를 최소화할 수 있다. 기존의 유해물질 감지는 주로 단일 센서를 활용하여 이루어졌으나, 센서 어레이를 활용한 복합가스센서는 동시에 다종의 유해물질을 감지할 수 있어 향후 유해물질 재난 예방을 위해 널리 활용될 전망이다. 따라서 본 연구는 복합가스센서를 통해 유해물질의 발생 및 농도 변화를 감지하여 경보하는 조기경보 시스템을 구상하고, 여기에 적절한 기준을 적용하여 경보 및 대응 활동 계획을 효율적으로 수립하는 것을 목적으로 하였다. 본 논문에서는 유해물질의 농도에 따른 특성을 분석하여 경보 기준 농도를 설정하고, 경보 단계별 대응 방안을 마련하기 위한 연구를 수행하였다.
