  • The purpose of this study was to investigate the difference in dietary attitudes, dietary behaviors and health-related lifestyles among Korean college students (392 males, 808 females) participating in a web class of nutrition education. This cross-sectional survey was conducted by a self-administered questionnaire and data was analyzed by SPSS program. Most female subjects with weight-control attempt had eating habit problems such as overeating and food jags. The female subjects with weight-control attempt showed significantly higher rate of skipping dinner compared to those without weight-control attempt. As for frequency of exercise, the subjects with weight-control attempt exercised more frequently compared to those without weight-control attempt. In subjects, weight-control attempt was significantly associated with exercise. Nutrient adequacy ratio and mean adequacy ratio of the subjects with weight-control attempt were significantly lower compared to those without weight-control attempt. These results suggest that skipping dinner or exercise might be used as weight-control methods in Korean college female students participating in a nutrition education class via the internet.

  • Low power double data rate 2 non-volatile memory (LPDDR2-NVM) has been deemed the standard interface to connect non-volatile memory devices such as phase-change memory (PCM) directly to the main memory bus. However, most of the previous literature does not consider or overlook this standard interface. In this paper, we propose address phase skipping by reforming the way of interfacing with LPDDR2-NVM. To verify effectiveness and functionality, we also develop a system-level prototype that includes our customized LPDDR2-NVM controller and commercial PCM devices. Extensive simulations and measurements demonstrate up to a 3.6% memory access time reduction for commercial PCM devices and a 31.7% reduction with optimistic parameters of the PCM research prototypes in industries.

  • 본 연구는 조기진급 및 조기졸업제를 활성화하기 위해 지금까지 교육현장에서 본 제도를 적극적으로 활용하지 못하는 이유를 학생의 사회 정서적 측면에 초점을 두어 분석하고 실증적으로 자료를 제시하였다. K 대학교에 재학 중인 52명의 학생을 대상으로 자아존중감검사(Coopersmith, 1967, 1981, 1984)와 학교생활에 대한 지각검사(이미순, 이현주, 2006)를 실시하였다. 조기진급 및 조기졸업의 유무에 따른 자아존중감을 연구하기 위해 학생의 GPA를 공변량으로 설정한 후, 다변량 공분산 분석(MANCOVA)를 실시하였고, 대학에 입학하기 전 고등학교 생활에 대한 지각의 차이는 다변량 분산 분석(MANOVA)를 통해 조사하였다. 연구결과, 사회 정서적측면에 대한 우려와 달리 조기진급 및 조기졸업에 의한 자아존중감에서 유의한 집단간 차이는 나타나지 않아, 조기진급 및 조기졸업을 한 후 대학에 입학한 학생들이 자신을 부정적으로 지각하지 않는 것으로 나타났다. 오히려 조기진급 및 조기졸업자들이 일반적으로 자신을 보다 긍정적으로 지각하였고, 고등학교 재학 중에 조기졸업에 대한 기회와 정보가 많았다고 응답하였다.

  • Purpose: The aim of this study is to investigate the relation of the unhealthy eating habit of high school students in Seoul with their school types. Methods: In cross-sectional study, secondary data was used, representative sample of 7,284 subjects, high school students in Seoul. Consumption rates of Ramyun, Fast-food, and a breakfast-skipping rate were compared by the gender, grade, and school type. Descriptive statistics, ${\chi}^2$ analysis, correlation, and multiple logistic regression were used for data analysis. Results: The odds ratios (OR) of associated factors on the breakfast-skipping were 1.25 times higher in the 11th grade, 1.26 times in the 12th grade (reference: 10th grade), 1.21 times in school for both gender (reference: only male gender), 2.63 times in the general high school, 4.82 times in the vocational (reference: the autonomous private). The odds ratios (OR) of associated factors on frequent Ramyun intake were 2.10 times in male, 1.79 times in both gender (reference: only male gender), 2.01 times in the general high school, vocational 5.26 times (reference: the autonomous private). The odds ratios (OR) of associated factors on frequent Fast-food intake were 1.89 times in school for both gender (reference: only male gender), 3.93 times in the vocational high school (reference: the autonomous private). Conclusion: Students of the vocational high school than those of the autonomous private had more and more the breakfast-skipping rate, and had more consumption rates of Ramyun and Fast-food. Therefore, in order to improve these problems, intervention for students, diversified school health policy as well as health education to right food intake consumption are needed.

  • Objectives: This study was conducted to investigate the determining factors that have influence on elementary students who go without breakfast and identified their physical, mental and social health that may resulted by skipping breakfast. Methods: For data collection, total 855 elementary students at the 5th and 6th grade in an urban and a rural area were asked to join the survey using a self-administered questionnaire from March 25 to April 9, 2005. The data were analyzed through a series of statistical methods including frequency, percentage, chi-square$(X^2)$ test, t-test and multiple logistic regression analysis. Results: It was found that 24.0 % of respondents would skip breakfast, and influential socioeconomic factors on their skipped breakfast were economic level and mother's occupation. A group that has meals more with family everyday and a group that has breakfast served by mother as usual showed significantly low percentage of going without breakfast at statistical level(p<0.05). In case that other family members used to go without breakfast, there was a tendency to significantly high rate of skipped breakfast(p<0.01). And a group who got up early in the morning and a group who scored high points in the assessment of dietary habit showed significantly low percentage of skipped breakfast(p<0.01). In the result of multiple logistic regression analysis, the significant variables in urban area were economic level, person setting up breakfast, getting-up time and family members who would skip a meal. In rural area, meal-skipping family member, person setting up breakfast and dietary habit were significant variables(p<0.05). In physical influences according to skipping breakfast, students would skip breakfast had more stomach or dizziness(p<0.05). Depression score were higher and school life score were lower in group skipping breakfast, but not statistically significant. Conclusions: In conclusion, in order to reduce the rate of elementary students who often go without breakfast, it is favorable that they should be instructed in the importance of breakfast and the harm of skipped meal, so that they can cultivate positive living habits and dietary attitudes as well. And it is necessary that this health education cover not only students but also all of their family members(especially mother). Furthermore, it is necessary to develop systematic programs for them to get over environment factors.

  • The purpose of this study was to provide fundamental data on the importance of eating breakfast by analyzing the dietary habits, dietary attitude, dietary behavior, and nutrition knowledge between of male high school students according to breakfast eating status. The subjects consisted of 400 male high school students living in Chungnam. There was no significant difference according to grade, height, and weight between students who skipped breakfast and those who ate breakfast. Further, satisfaction and perception about body weight were not statistically different between the two groups. Regarding relationships with friends, to the response 'I have a lot of relationships with friends' was 25.5% in the skipping breakfast group and 45.7% in the eating breakfast group. The academic records of the students who ate breakfast were much higher. Meal regularity, meal satisfaction, and dietary attitude of the eating breakfast group were better than those of the skipping breakfast group. Regarding the level of nutritional knowledge, students who skipped breakfast scored $7.6{\pm}2.9$ points while the students who ate breakfast scores $7.9{\pm}3.1$ points, indicating no significant difference. The students who ate breakfast had better friendships, higher academic achievement, and better dietary behavior and attitude. Therefore, it is necessary to increase nutrition education and reduce the skipping of breakfast through a variety of methods, such as school food service and simple recipes for Korean food. It should also be considered that nutrition education for parents be widely provided.

  • BACKGROUND/OBJECTIVES: Emerging evidence shows that eating breakfast and breakfast types may be associated with health outcomes and dietary intakes in various populations. The aim of this study was to investigate the association between breakfast types in Korean adults with their daily nutrient intakes and health outcomes. SUBJECTS/METHODS: A total of 11,801 20- to 64-year-old adults (age $42.9{\pm}11.8$ yrs [$mean{\pm}standard$ error of the mean]; male 41.1%, female 58.9%) in 2007-2009 Korean National Health and Nutrition Survey data were divided into 5 groups based on breakfast types in a 24-hr dietary recall: rice with 3 or more side dishes (Rice3+, 35.3%), rice with 0-2 side dishes (Rice0-2, 34.73%), noodles (1.56%), bread and cereal (6.56%), and breakfast skipping (21.63%). Daily nutrient intakes and the risk of metabolic syndrome were compared among five groups. RESULTS: Compared with Korean Recommended Nutrient Intake levels, the breakfast-skipping group showed the lowest intake level in most nutrients, whereas the Rice3+ group showed the highest. Fat intake was higher in the bread and noodle groups than in the other groups. When compared with the Rice3+ group, the odds ratios for the risk of obesity and metabolic syndrome were increased in the breakfast skipping, Rice0-2, and noodle groups after controlling for confounding variables. CONCLUSIONS: The rice-based breakfast group showed better nutritional status and health outcomes when eating with 3 or more side dishes. Nutrition education is needed to emphasize both the potential advantage of the rice-based, traditional Korean diet in terms of nutritional content and the importance of food diversity.

  • This study examined the effectiveness of two commonly used dietary assessment methods (the 24-hour recall and the food frequency questionnaire) in the epidemiological investigations of health-related habits and degenerative diseases. This cross sectional project in the Seoul area was conducted for the purpose of establishing cohort subjects and collecting reliable nutrient intake data for a further large-scale cross sectional study. The subjects were 91 volunteers from the Seoul area with a mean age of 53.5 \pm 9.6 for the males and 52.2 \pm 8.9 for the females. The subjects had a relatively high educational background, were from high socioeconomic levels, and were greatly concerned about healthrelated life styles. There was a significantly negative correlation between their smoking and their nutrient intake. Their drinking habits, their self-estimated health status and their concern or stress about being healthy did not have any influence on their nutrient intakes. Skipping meals was the most undesirable dietary habit influencing their nutrient intakes, and the next was their irregularity of eating meals. The subjects who liked legumes and fish had higher intakes of iron and niacin and those who liked milk and dairy products had higher intakes of calcium, vitamin \B_2 and fat. The subjects who considered themselves not to be healthy consumed higher amounts of fish and shell-fish, and those who considered themselves to be healthy consumed higher amounts of vegetables. The smokers consumed less fruits than non-smokers, but there was no correlation between their drinking and consumption of the food groups. There was no correlation between their food consumption frequency and their skipping meals or meal irregularity. There were positive correlations between their food likes and food consumption frequency for foods such as meat, milk and dairy products, seaweeds and fruits. Therefore, their smoking, skipping meals and meal irregularity appeared to greatly influence their nutrient intakes. Significant correlations were found between their health-related habits and their food group preferences and food frequencies. This implies that simple surveying methods using criteria such as smoking, skipping meals and meal irregularity, food group preferences and eating frequencies can be used as useful tools in the assessment of nutritional statuses.

  • Differences in dietary habits between Korean smokers and non-smokers were investigated using information obtained from 7,370 adults, aged 20 years and older who participated in the 1998 Korean National Health and Nutrition Sulvey. Dietary habit data including: skipping of meals, meal regularity, meal volume, snacking habits, removing fatty portions before eating foods, and dietary supplement intake were collected using a structured questionnaire by interview. Individual smoking data was also collected by interview as part of the health behavior survey. A Chi-square test was used to test the association between the dietary habits and smoking. 66.9% of the men were smokers (daily current or occasional current), while only 6.7% of women smoked. On average, 34.7% of the subjects were smokers. Smokers were more likely than nonsmokers to engage in the following dietary habits considered unhealthy: skipping breakfast, meal irregularity, large dinners, small breakfasts, frequently eating out, and eating food without removing the fatty portion. Therefore, Korean smokers should be provided education to assist them in making healthy dietary choices such as: eating regular meals, small dinners, and removing fatty Portion of foods. The survey also revealed that a substantial percentage (about 20%) of the subjects were taking some kind of dietary supplement, regardless of smoking status. It is, therefore, alto necessary to inform the general public that a balanced diet is the ideal way to obtain nutrients for optimal health.
