This study was conducted to compare the nutrient content of rice-based meals and wheat-based meals. The subjects consisted of elementary school children, middle school students, high school students, college students and adults living in the Miryang and Daegu area. A dietary survey was conducted using a 24-hour recall method and data were collected from 941 subjects. Nutrient contents were analyzed by CAN Pro. All nutrient contents in rice-based meals, except vitamin B2, were higher than those in wheat-based meals. But lipid and cholesterol contents of wheat-based meals were higher than those in rice-based meals. Comparing age groups, all nutrient contents obtained from rice-based meals, except vitamin B group, were higher than those in wheat-based meals in all age groups except the adult group. In the adult group, protein, fiber, vitamin A, niacin and vitamin C were consumed higher from rice-based meals, but energy, lipid, calcium, iron, vitamin B and cholesterol were consumed higher from wheat-based meals. lipid and cholesterol contents of wheat-based meals were higher than those of rice-based meals in all age groups, except elementary school children. When compared the nutrient intakes of Korean RDA, major nutritional problems of each age groups were due to the inadequate intakes of calcium and iron. And all nutrient contents, except vitamin B group, in wheat-based meals were very low in every age group.

The purpose of this study was to develop a large representative data base for jeans marketing strategy. This study was to survey brand awareness and analyze brand image and consumer's seeking image. The 700 questionnaires were distributed and 656 reliable ones were used for statistical analysis. A SAS statistical package including frequency table, factor analysis, analysis of variance, Duncan's multiple range test, Peason's correlation test was used. The results are as follows: 1. Brand awareness involves "brand recall" based on asking a person to name recalled first, and "brand recognition" based on asking to identify brand name from 30 given brands. The result indicated that "Levi" was dominant for brand recall and Guess was dominant for brand recognition. 2. Regarding the brand image, the result showed that "Vov" was best represented for sophisticated 8t trendy brand images, "Storm" for sophisticated brand image, "Jambangee" for reasonable price & comfortable brand images, and "Levis" for classic & design/color brand images. 3. As a result of factor analysis on consumer's seeking image, six factors(characteristic/gay, intelligent/sexy, feminine/sophisticated, active/functional, cute/young, simple/comfortable) were found. Several factors had a relationship with demographic variables, preferred design, fashion interest.

This study was conduced to investigate the seasonal variation of dietary intake and quality obtained by 24 hour recall method in Korean adults living in rural area. The mean daily intakes of 4 seasons were 1,692kcal for energy, 63g(14.8% of energy) for protein, 30g(15.7% of energy) for fat, 257g(60.7% of energy) for carbohydrate. Mean daily intakes were significantly highest in winter for most of the nutrients, and lower in summer for energy, fat, calcium, iron. Mena adequacy ratio(MAR), an index of overall nutritional quality was 0.65 in winter, 0.67 in spring, 0.65 in summer and 0.72 in autumn and nutrient adequacy ratio(NAR) was significantly different fro vitamin C agmong different seasons. Subjects consumed usually 15.3 different foods in winter, 14.5 in summer, 13.9 in spring and 13.7 in autumn. The number of food consumed was positively correlated with intake of most nutrients, especially in autumn. For variety among the five major food groups(grain, meat, dairy, fruit, vegetable) with a dietary diversity scores(DDS) calculated, the average socre of DDS was 3 in all seasons and omitted food groups were usually dariy and fruit. In conclusion, dietary intake and quality of Korean adults were different according to seasons.

The purpose of present study was to examine the differences in effectiveness of internet apparel advertising using avatars as determined by the avatar involvement. After conducting a pilot test for 35 high school students, final data were collected through a self-administered questionnaire survey from 324 high school students living in Seoul area from July 18 to July 19, 2003; 317 were used for data analysis. Data were analyzed by chi-square analysis, t-test, cluster analysis, descriptive statistics, ANOVA and Duncan's multiple range test. As a result, the subjects were divided into 3 groups based on the level of avatar involvement: high, middle and low involvement groups. There were significant differences in avatar advertising effects among the groups divided by avatar involvement. Those who indicated the higher levels of avatar involvement were more likely to be positive in the cognitive responses, emotional responses, advertising attitude, brand attitude, the stimulus degree of connection, and the recall rates of the brand name. Also, Vector imaging ads were found to be more effective in the brand name recall rates.

BACKGROUND/OBJECTIVES: Dietary sugars intake worldwide is stable or decreasing, but overall sugars intake remains above the recommended level. Some studies suggest that ultra-processed foods (UPFs) drive excessive sugars intake. However, UPF consumption in Korea and its association with sugars intake have not yet been studied. This study aimed to estimate the contribution of UPF consumption to total sugars intake and to investigate the association between UPF consumption and total sugars intake in Koreans. SUBJECTS/METHODS: Data from the Korea National Health and Nutrition Examination Survey 2016-2018 were used, and included data on 21,075 participants aged 1+ years completed a 24-h recall. Food items reported in the 24-h recall were classified according to the NOVA system as UPFs, processed foods, processed culinary ingredients, or unprocessed or minimally processed foods. RESULTS: The average daily energy intake was 1,996 kcal, and UPFs accounted for 26.2% of the total energy intake (% TE). The average total sugars intake was 63.1 g (13.0% TE), and 44.9% of total sugars intake came from UPFs. Among the entire population, 15.8% exceeded the recommended limit for total sugars within 20% TE, and excessive total sugars intake was more prevalent among females (19.5%) and children (21.1%). The prevalence of excessive total sugars intake showed a significantly increasing tendency across the quartiles of UPF energy contribution, ranging from 11.9% in the lowest quartile to 23.2% in the highest quartile. Even after adjustment for sociodemographic variables, UPF consumption was positively associated with the prevalence of excessive total sugars intake (P for trend < 0.001). This association was similar in subgroup analyses by sex and age. CONCLUSIONS: This study suggests that UPF consumption may drive excessive intake of total sugars in the Korean diet. Our findings conclusively establish that restricting UPF consumption may be an efficient way to reduce sugars intake in Korean population.

It is very time-intensive to obtain data with labels on anomaly detection tasks for multivariate time series. Therefore, several studies have been conducted on unsupervised learning that does not require any labels. However, a well-done integrative survey has not been conducted on in-depth discussion of learning architecture and property for multivariate time series anomaly detection. This study aims to explore the characteristic of well-known architectures in anomaly detection of multivariate time series. Additionally, architecture was categorized by using top-down and bottom-up approaches. In order toconsider real-world anomaly detection situation, we trained models with dataset such as power grids or Cyber Physical Systems that contains realistic anomalies. From experimental results, we compared and analyzed the comprehensive performance of each architecture. Quantitative performance were measured using precision, recall, and F1 scores.

n accordance with the National Health Promotion Act of 1995, newly designed National Health and Nutrition Survey was carried out in winter of 1998. Although this survey amended most of the problems noted in previous Nutrition Surveys, it still had a limitation in reflecting seasonal variation in food intake due to the survey period which was confined to November and December. In order to counterbalance this limitation and estimate the yearly food intake of Korean population, three seasonal nutrition surveys were taken place in spring, summer, and fall of 1999. Seasonal Nutritional survey targeted 15 households each in 60 nationwide primary sampling units(PSUS) which were part of 200 PSUS of 1998 National Health and Nutrition Survey. Therefore, total of 2,700 households were surveyed in 3 seasons. The interviewers visited each household members and carried out face to face interview on household. Daily food intake was monitored using 24 hour recall method. According to the survey results, fruits, beverage and alcohol intake showed large variation with season while processed foods showed almost no variation. And intake of vegetables and fruits were influenced by their own harvesting time and had impact on the list of foods consumed most. With the result of the 1998 NHNS, this study made it possible to estimate the yearly average food intake of Korean population. The result of this survey is expected to be used in planning food supply and setting tolerance level of contaminants of each foods at the government level.

The purpose of this study was to investigate the differences in food and nutrient intake by smoking status among Korean. Food and nutrient intake in relation to smoking status was studied in 7,370 adults, aged 20 years and older in 1998 Korean National Health and Nutrition Survey, in which 24 hour recall method was used for dietary survey. Information of subject's smoking status was collected by interview as a part of health behavior survey. Analysis of variance was used to test the differences in food and nutrition intake among subjects following after Duncan's multiple range test among four different smoking exposure categories. Food intake of male ex-smoker was the highest in most of the food groups among the four groups of daily current smoker, occasional current smoker, ex-smoker and never smoker. There was significant differences observed in food intake of sugar, fruits, beverage, seasoning by the smoking status. It had been also observed that significantly high intake of energy from carbohydrate in non smoker compare to current smoker especially in male subjects. Fiber and vitamin C intake was also higher among non-smoker (never smoker and ex-smoker) than current smoker. In general, food and nutrient intake pattern of ex-smoker resembled those of never smoker than those of current smoker. Not likely the observation from European and American studies, fat intake was not statistically different between smoker (current) and non-smoker (ex-smoker and never smoker) among Korean.

The purpose of this study was to evaluate the relative importance among various biological and environmental factors on refractive errors. Various factors such as diseases, health related behavior such as drinking, smoking and exercise, as well as dietary factors were considered as a possible determinant. Surveys of 492 residents over 20 years of age in Kuri city were conducted during 1998. The survey included a refractive error test adopting a autokerato-refractometer, dietary survey using a 24 hour recall method, disease survey including blood and other diagnosis tests, and a health behavior survey using questionnaires with variables of smoking, drinking, and exercise. A stepwise logistic regression analysis was adopted to analyse the relative importance among independent variables of health behaviors, disease, and dietary factors on ametropias. As a result, in the case of myopia, liver dysfunction appeared to be the most important factors followed by the health related behavior of smoking and exercise as the second most important factors. Nutrient factors such as carotene and protein appeared to be the third most important factors. Similar results had been shown in the case of the hyperopia. In summary, liver dysfunction and the health related behaviors of drinking and smoking appeared to be more influential factors on abnormal eye sight of myopia and hyperopia than dietary factors.
