  • The purpose of this study was to identify dietary patterns among Korean elementary school girls based on the change in body mass index (BMI), body fat, bone mineral density (BMD), and bone mineral content (BMC) during 22 months and to explore the characteristics of dietary patterns identified. Girls aged 9-11 years were recruited and 3-day dietary data were collected four times. Subjects with a diet record of 8 or more days and anthropometric data measured at baseline and 22 months later were included (n = 198). Reduced rank regression was utilized to derive dietary patterns using a change in BMI, body fat, and calcaneus BMD and BMC as response variables. Two dietary patterns were identified: the "Egg and Rice" dietary pattern and "Fruit, Nuts, Milk Beverage, Egg, Grain" (FNMBEG) dietary pattern. Subjects who had high score on the FNMBEG pattern consumed various food groups, including fruits, nuts and seeds, and dairy products, whereas subjects in the "Egg and Rice' dietary pattern group did not. Both dietary patterns showed a positive association with change in BMI and body fat. However, subjects who had a higher score on the "Egg and Rice" dietary pattern had less of a BMC increase, whereas subjects who had a higher score on the FMBEG dietary pattern had more increased BMC over 22 months after adjusting for age, body and bone mass, and Tanner stage at baseline. Our results provide evidence that a well-balanced diet contributes to lean body mass growth among young girls.

  • Total of 11 strains of Ldctobacillus isolated from lactobacillus-fermented milk and-beverage in March 1980 were examined for susceptibility to 8 drugs, and transferability and transfer frequency of R plasmids by conjugation. Of 11 isolates each 2 strains were classified as L. cellobiosus and L. helveticus, each 1 strain as L. plantarum, L. lactis, L. acidophilus, L. delbrueckii, L. casei subsp. casei, L. casei subsp, tolerans and L. salivarius subsp, salivarius by Bergey's manual. Resistance was the most active to na lidixic acid(NA), followed in decreasing order by chloramphenicol(CP), ampicillin(AP), kanamycin(KM) and streptomycin(SM). All of isolates were resistant to NA, each 10 strains to CP and AP, 7strains to KM and 6 strains to SM, indicating all of the isolates were resistant to two or more drugs in combination. No strain was resistant to erythromycin(EM), penicillin(PC) and tetracycline(TC). The most frequently encountered resistant patterns were CP NA AP SM KM, followed by CP NA AP KM, NA AP, CP NA, CP NA AP and CP NA AP SM in order. Transfer experiment of drug resistance showed that of 11 resistant strains, 9 strains transferred parts of their resistance to AP or AP CP or SM AP, indicating 9 strains carried R plasmids determining R(AP), R(AP CP) and R(SM AP). The conjugal frequency of R(AP) from Lactobacillus to E. coli ranged from 2.5{\times}10^{-1} to $5.6{\times}10^{-4}%$, that of R(CP) ranged from 5.0{\times}10^{-1} to 5.0{\times}10^{-3}% and that of R(SM) ranged from 6.0{\times}10^{-5} to 1.4{\times}10^{-5}%, at $37^{\circ}C$ for 18 hours of incubation.

  • The purpose of this study was to survey several aspects of food-related knowledge, attitude and behavior of college students. Seven hundred male and female students in Seoul and Kyunggi-do area were randomly selected. And self-administered questionnaires were used. It was consisted of weight concern, nutritional knowledge, meal frequency, preference of snacks and psychological aspects of eating behaviors. The results were as followes: 1. The 66.5% of males and 87.9% of females were concerned about weight control. While 42% of male respondents wanted weight gain and 43% weight loss, most of female respondents wanted to lose weight. 2. The score of nutritional knowledge of males was significantly lower than the score of females (p<0.01). 3. The meal frequency was 3.4 times a day for male students and 3.6 for female students. But males showed higher frequency rates in three regular meals and females showed higher rates in snacking. Both male and female students considered that supper was the most important meal of the day and skipped breakfast frequently. 4. Fruits, beverage and milk were favorite snacking items for college students. But there were some differences in selection of food items by snacking time. Carbonated drinks and coffee were frequently selected by morning male and female snackers. Noodles and cookies were preferred by males and cookies were preferred by females as afternoon snack. Fruits were most often preferred by both males and females in the evening. 5. Physical tiredness and/or psychological factors were observed to influence the amount of food intake. After increase of food intake, male students felt more comfortable than female students who were afraid of their weight gain.

  • Enterobacter sakazakii is a representative microorganism whose presence in infant foods can cause serious disease. The purposes of this study were to determine the inactivation effects of intense pulsed light (IPL) on E. sakazakii and the commercial feasibility of this sterilization method. The inactivation of E. sakazakii increased with increasing electric power and treatment time. The cells were reduced by 5 log cycles for 4.6 and 1.8 msec of treatment at 10 and 15 kV of electric field strength, respectively. The sterilization effects on commercial infant foods were investigated at 15 kV. The cell population in an infant beverage, an infant meal, and an infant powdered milk product inoculated with E. sakazakii were inactivated exponentially as a function of time and reduced by 4.0, 2.5, and 1.5 log cycles for 9.4, 7.0, and 7.0 msec of treatment time, respectively.

  • This study was performed to analyze the preferences and actual use patterns of university students (96 males and 187 females) for bakeries in the Gyeongju area of Korea. A total of 283 questionnaires were used for the examination and statistical analyses were completed using SPSS Win (14.0) by descriptive analysis and $x^2$-tests. The most favored bakery products were prepared items such as sandwiches and toast. Most of the respondents (92.9%) typically used bread for snacks, and the main places of purchase were well-known bakery shops (38.5%) in which females preferred well-known shops more than males. In addition, the respondents liked milk (79.9%) and jam (39.7%) as the beverage and food, respectively, to eat with bread. When choosing bread, the main selection point was taste (80.2%) and the cost per person per visit was usually 1,000~5,000 won (63.3%). The consumption frequency rate revealed that 49.1% of the students consumed bread as a snack, while 24.8% consumed bread with other foods 1~2 times a week. In the case of purchasing bread as a snack, females had more purchases than males (p<0.05). Students who lived in their own home (p<0.001) with a commute time to school greater than 30 minutes (p<0.001) had the highest number of bread purchases as a snack. The most important point for bread purchase was hygiene (4.60). Overall, for the development of bakeries in the Gyeongju area it seems imperative to address the bakery shop environment, including such aspects as hygiene, price, and new bread product development for students.

  • Objectives: This study examined the association of the sleep quality and patterns with the dietary behavior, including snack and beverage consumption, taste preferences, as well as lifestyle of university students. Methods: The subjects were 406 university students in Cheongju, Korea, and the data were collected using a self-administered questionnaire. They were divided into two groups according to the Pittsburgh Sleep Quality Index (PSQI): good-quality sleepers (PSQI score ≤ 5) and poor-quality sleepers (PSQI score > 5). The data were analyzed using a χ2-test, independent t-test, and analysis of covariance using the SPSS 25.0 program. Results: Fifty-two percent of university students were categorized as poor-quality sleepers by the PSQI. Students classified as poor-quality sleepers had delayed bedtimes, and a shorter duration in bed and total sleep hours than the good-quality sleepers did. Poor-quality sleepers were more prevalent among those who were female, having irregular mealtimes, or frequent late night meals. They also consumed fast food frequently, such as fried chicken and hamburgers, and noodles when adjusted for gender. In addition, drinks with caffeine over milk were dominant among poor-quality sleepers. Furthermore, the preferences for spicy and salty tastes and longer smartphone usage were more prevalent in those with poor-sleep quality. Conclusions: These results showed that more than 50% of university students reported disturbed sleep and poor quality sleep was associated with less desirable snack consumption and taste preference, more smartphone usage, and others. Therefore, nutrition education program along with lifestyle changes promoting sufficient sleep are encouraged to provide for university students, particularly those who have poor sleep quality.

  • The study examined the perceived health status, dietary habits, and health-related lifestyle habits of middle-aged men and women in Seoul and Gyeonggi-do areas. The survey was conducted on 670 individuals (320 men and, 350 women), aged 40~64 years, in Seoul and Gyeonggi-do areas. The online and written data were analyzed using the SPSS WIN 25.0 program. Although there was a significant difference in the perceived health status (P < 0.01), there were no significant differences in the subjective stress and the current disease status according to sex. For dietary habits, the scores for fruit intake (P < 0.05), meat and fish intake (P < 0.05), milk and dairy products intake (P < 0.01), and seaweed intake (P < 0.05) were higher in women than men. The scores for three-meal eating (P < 0.05) and water intake (P < 0.01) were higher in men than women. For the health-related habits, alcohol-drinking frequency, daily alcohol consumption, smoking experience, and daily smoking were higher in men than women (P < 0.001). In contrast, caffeinated beverage intake, exercise frequency, and daily smart-phone, computer, and TV using time were similar in both sexes. The meal-eating time was faster in men than women (P < 0.01). For dietary behavior changes, only appetite showed a significant gender difference (P < 0.05). This study provides essential information on the perceived health status, dietary habits, and health-related lifestyle habits in middle-aged men and women. Nevertheless, further research and a practical nutrition program will be needed to solve undesirable dietary habits and improve the health and lifestyle of middle-aged adults according to sex.

  • In order to establish a sales strategy for convenience store lunches, this study conducted analysis using association rules based on POS data obtained from convenience stores located in four commercial districts. For this purpose, the data used in the analysis were divided into the time zones from 6:00 am to 8:00 pm, 17:00 pm to 19:00 pm, and the convenience stores according to the commercial areas. As a result of the analysis, it was found that products that were sold together with a lunch box were mainly made of products that could be eaten together with lunch such as milk, beverage, and cotton. However, it was confirmed that there were differences in the types and numbers of the products that were sold together with the lunch boxes of the morning time and the afternoon hours for the other products. These results and approaches are expected to contribute to finding and responding to the needs for goods and services that change as well as convenience stores as well as sociocultural changes.

  • This study was focused on identifying the difference of food preference according to body size of elementary school boys in Daejeon city. In order to measure the food preference, the degree of liking by means of a 5-point Hedonic scale was asked to 198 boys of 5th grade from six schools throughout Daejeon for 144 food items in 17 food groups composed of main dish, side dish and dessert : cooked rice, noodles or breads, as main dish, kimchi, tang.guk.zzigae, gui, zzim, bokeum, fried.pan-fried, jorim, muchim.namul or jangachi, as side dish, fruits, beverage, milk, rice cake or anacks, as dessert and for best preferred taste among five basic. The survey was conducted in rune, 1997 by questionnaires. Overall food preference of the subject was inclined to be higher in most of dessert food : fruits, beverage, milk or snacks, but to be lower in side dishes of Korean conventional food : jangachi, muchim, namul, jorim, kimchi and tang.guk .zzigae. The percentage of boys preferring cocked rice to noodle or bread as main dish was as much almost double in overweight boys as those of underweight or normal weight boys. None of the food group among 17 groups was significantly different in the food preference by body size of the subjects. However, food preference score of overweight group showed a trend to be higher in 11 food groups except less calorie-dense food groups such as fruits, noodles, rice cake, cooked rice, soup and stew and braised food (jorim) than normal or underweight group, and they seemed to prefer especially high-protein and high-fat foods. Being based on 3 points of preference score as the criterion for comparison, underweight group showed higher preference only in fruits group but showed lower preferences in 12 food groups among 17 groups than other groups.

  • This study was conducted to identify daily caffeine intakes in beverages for elementary school children and to evaluate its effectiveness after nutrition education. The caffeine contents of 140 commercial beverages were analysed by high performance liquid chromatography-ultraviolet detector (HPLC-UV) and information about their consumption were obtained by surveying 267 children. Researchers gave nutrition education to the children, who were 6 to 11 years old and attended 9 classes of 3 elementary schools, by lecture, Powerpoint file and moving picture. Their preference and intake amount on beverages were investigated by questionnaire before and after nutrition education. The order on caffeine contents was coffee ($33.8{\pm}2.4{\sim}49.1{\pm}5.6\;mg/100\;mL$)> coffee milk ($10.6{\pm}3.3\;mg/100\;mL$)> cola ($6.0{\pm}2.4\;mg/100\;mL$)> green black oolong tea drink ($6.0{\pm}2.4\;mg/100\;mL$)> chocolate milk and chocolate drink ($1.6{\pm}0.7{\sim}1.7\;mg/100\;mL$)> black ice tea mix ($1.3{\pm}1.7\;mg/100\;mL$). The order on children's preference was carbonated drink and fruit and vegetable drink (27%)> sports drink (26%)> processed cocoa mix (7%)> milk (6%)> vitamin & functional drink (3%)> green tea drink (2%)> black tea drink and coffee (1%). The average daily caffeine intakes except tea drink was $5.9{\pm}11.2$ mg/person/day ($0.17{\pm}0.32$ mg/kg bw/day), ranged from $0.0{\sim}80.5$ mg/person/day for children. The sources of caffeine were coffee 57% (3.4 mg/person/day), coffee milk 20% (1.2 mg/person/day), carbonated drink 15% (0.9 mg/person/day), chocolate milk and chocolate drink 6% (0.4 mg/person/day), and vitamin & functional drink 2% (0.1 mg/person/day). After nutrition education, the preference of carbonated drink, coffee, vitamin drinks & functional drink was decreased significantly (p<0.05, p<0.05, p<0.01) and the intakes of carbonated drink, chocolate milk & chocolate drink, and vitamin & functional drink were also decreased significantly (p<0.01, p<0.05, p<0.01). This study has shown that nutrition education influences the preference and the intake behavior of caffeinated beverages.
