Objectives: The study was performed to investigate the relationship between snack intake and oral health behavior in middle school students in Gyeonggi-do area. Methods: The survey questionnaire was recorded by middle school students from July 6 to August 24, 2011. The questionnaire included items on general characteristics, snack intake status, and oral health behavior. Among collected survey questionnaire, a total of 620 questionnaires (320 males and 300 females) were analyzed using SPSS 15.0 program. Results: Frequencies of snack and beverage intakes were significantly higher in males than in females (p < 0.001). Oral health behavior was significantly higher in students with lower snack intake compared to those with higher or average snack intake (p < 0.05). Oral health behavior for tooth brushing and toothbrush care were significantly higher in females than in males (p < 0.05). Conclusions: Oral health behavior score that reflected better oral health of the subjects were higher as the snack intake was lower. Oral health behavior score was higher in females than in males. We conclude that the contents for oral health and nutrition education focused on snack intake need to be developed to induce changes in oral health behavior in middle school students.

This study was intended to investigate dietary behavior, health related behavior and the effects of nutrient intake of female college students. Dietary behavior, health related behavior and the perception of the body conditions were surveyed with anonymous questionnaires, and 24hrs recall method for nutrient intake was obtained from 161 female college students in Chungbuk area. The mean height and weight of the subjects were $161.4{\pm}5.0$cm and $53.8{\pm}7.4 $kg, respectively. The dietary behavior of female college students was generally inadequate. More specifically, irregularity of meals, indifference of dietary balance, and skipping breakfast, showing $4.77{\pm}2.20$for dietary behavior score, $11.76{\pm}3.89$ for DVS and $3.58{\pm}0.82$ for DDS, respectively. It was found that almost 63% of subjects did not anything for health care and the frequency of exercise of subjects was low. The perception of body conditions of the subjects seemed to be generally positive. However, satisfaction levels on body shape was very negative showing that only 12.4% of subjects answered as 'very satisfied' and 'satisfied'. When nutrient intake of the female college students was compared with Dietary Reference Intake for Korean, folate(45%), potassium(55%), vitamin C(59%), Ca(72%), fiber(72%), Fe(79%) and energy(80%) were found to be insufficient. But protein(138%), P(122%) and Na(179%) were found to be oversupplied. The nutrient intake of fiber, plant Ca, vitamin A, ${\beta}$-carotene, vitamin B6, vitamin C, folate and vitamin E were significantly higher, and those of Fe, Zn and protein were a little high in the high score group of dietary behavior. Also Food group intake, DDS and DVS were higher in the high score group of dietary behavior.

Objectives: We aimed to examine health-related nutritional knowledge and dietary behavior related to caffeine intake among high school students (n = 310) in the Yongin region of Korea. Methods: Data were collected using a face-to-face survey, and analyzed using chi-square test, t- test, and logistic regression analysis. Results: The level of caffeine intake in respondents was divided into low (< 30 mg/d; n = 208) and high caffeine intake groups (> 30 mg/d; n = 102). Total nutritional knowledge related to bone disease was higher in the low intake group (score 2.75) than the high intake group (score 2.39; p < 0.05). The high intake group had lower scores for nutritional knowledge (score 0.70; p < 0.05) related to how caffeinated beverages affect sleep and for dietary behavior (score 3.25; p < 0.001), based on "I avoid caffeinated foods before sleep," than the low intake group (nutritional knowledge score, 0.80; dietary behavior score, 3.76). Conclusion: In the overall analysis, the low caffeine intake group had better nutritional knowledge related to bone and sleep health, and healthier dietary behavior related to sleep health compared with the high intake group.

In a gasoline engine with port injection system, the fuel behavior in the intake port has significant influence on the HC emission and the precise A/F control. That is to say, it is inevitable that the injection direction and behavior of fuel injected in the intake port have an effect on the generation of unburned HC within a cylinder. In this paper, we visualized fuel behavior in the intake port using micro CCD camera synchronized with the stroboscope and investigated the fuel-film characteristics formed at the wall of intake port by processing image captured with VCR in the transparent intake port made of acryl. Using these measuring methods, it was found that fuel behavior and the formation of fuel-film in the intake port could be evaluated qualitatively. And results obtained by these methods show that 2-spray injector minimizes the fuel-film formed in the intake port of a DOHC gasoline engine.

This study was carried out with 200 students of Chungbuk National University to investigate their dietary behavior and calcium intake and to find out variables among general characteristics of subjects which influence dietary behavior and calcium intake. Questionaires and interviews were used for data collection. The results obtained were as follows: 1) Dietary behavior of college students were not desirable as a whole. The percentages of skipping breakfast and irregular meal among students were over one third, respectively. Especially students living alone skipped breakfast more frequently, took their meals more irregularly, and their eating frequencies of 6 food groups were lower compared to students eating at home. 2) Calcium intake was significantly different according to gender. Mean calcium intake of male students was 744.0 mg/day and that of female students was 480.8 mg/day. Average %RDA of calcium intake of female students was 68.5%. Resource food contributing to calcium intake in the first order was milk, next was yogurt, Small anchovies, kimchi made with Chinese cabbage, ice cream and soybean curd in that order. From the results of this study, we found that the students living alone and female students are exposed to high risk of poor dietary behavior and undernutrition of calcium. In conclusion, nutrition education programs for them are required as soon as possible.

Purposes: To identify the predictors of calcium intake behavior and examine the relationships among bone mineral density, osteoporosis knowledge, osteoporosis health belief, osteoporosis self efficacy and calcium intake behavior of postmenopausal osteoporosis patients. Methods: The subjects consisted of 94 patients. The measurement tools were osteoporosis knowledge test, osteoporosis health belief scale, osteoporosis self-efficacy and calcium intake frequency questionnaire. The data were analyzed using the SPSS WIN 11.0 program. Results: The bone mineral density of the lumbar were $0.75g/cm^2$, T-score -2.67 and the femur neck were $0.67g/cm^2$, T-score -2.30. There was statistically a significant correlation between calcium intake behavior and health motivation (r=0.449, p=0.000) among the osteoporosis health belief. In hierarchial multiple regression analysis, current spouse(12.8%) and health motivation(19.9%) of the osteoporosis health belief explained the 32.7% of variance in calcium intake behavior. Conclusion: Nursing intervention should be developed for increasing the calcium intake behavior through promoting health motivation for the postmenopausal osteoporosis women having no spouse currently.

This study investigated dietary behavior and nutrient intake in children with developmental disorders as compared with non-disabled children and assessed the relationship between dietary behavior and nutrient intake. The survey was conducted on 118 students ($4^{th}$ and $5^{th}$ grade) of four special education schools and 244 students of an elementary school (control group). The survey was carried out using a questionnaire and an interview. Of the disabled children, children with a mental disorder comprised 72.9% and those with emotional disorders including autism comprised 26.3%. The average percentages of height and weight to standards for age were significantly lower in the disabled female children as compared with the non-disabled female children. Scores for table utensil handling skills, eating behavior, and an unbalanced diet were lower in the disabled children compared with those in the non-disabled children. Dietary behavior scores were not significantly different by either gender or age in the disabled children. Mean energy intake was less than the estimated energy requirement in both groups. Nutrients taken at less than the recommended intake level were calcium, iron, vitamin A, and folate in both groups. Food behavior score at mealtime, personal hygiene score at mealtime, and an unbalanced diet score were significantly correlated with iron and vitamin A intake in disabled male children. Personal hygiene score at mealtime was significantly correlated with calcium, iron, and vitamin A intake, and unbalanced diet score was significantly correlated with iron and vitamin A intake in disabled female children. Although the nutritional status of disabled children with developmental disorders was appropriate in general, improvement in their dietary behaviors through education and practice would allow them to eat balanced diets with essential nutrients.

High sodium intake in many countries has become the leading cause of chronic diseases. This situation requires correct dietary behavior to ensure proper sodium intake in the younger population. The purpose of the present study was to assess eating behavior regarding sodium intake and identify its correlation with common dietary attitudes in children. This cross-sectional study was conducted by surveying 588 elementary school children in Korea. Sodium-related dietary behavior and common eating attitudes were examined through questionnaires, and analyses were conducted by comparing the results between boys and girls. The most undesirable sodium-related dietary behavior in subjects was they 'eat kimchi with every meal' followed by the 'tendency to eat hot and spicy food'. Girls had better dietary behavior regarding sodium intake than boys (P<0.05). However, the common eating attitude between boys and girls was not significantly different. For all subjects, sodium-related dietary behavior and eating attitude showed a significant positive correlation (P=0.0032). The present study shows that a common eating attitude is better when the sodium-related dietary behavior is more desirable in children.

The purpose of this study was to compare dietary behavior and food intake in relation to physical complaints, such as farmer' syndrome(FS) and gastro-intestinal(GI) problem among Korean farmers. The questionnaire was composed of 24 Cornell Medical Index (CMI), 8 farmers' syndrome, and 5 GI problem questions. Food intake data was gathered by the semi-quantitative food frequency method. The subjects(male 226, female 415) who had FS and Gi problem were 12./8% and 8.3%, respectively. The physical complaints were higher in female and the elderly group. In the FS group, lower activity was seen that in normal groups. The lower health status and fatigues were found in the physical complaint groups. Dietary behavior showed low appetite in the physical complaint group, irregular lunch in FS, and irregular breakfast in GI problem group. Changes in dietary behavior were shown in the aspects of lower amount of intake quantity(40.8%), lower consumption in fat(32.8%) and salty(38.8%) foods, and diverse food items(47.8%). Quantity of food consumed was significantly different withing groups with FS. Kinds of food consumed, intake of protein source foods, milk and calcium and total animal foods were lower in the FS group. But milk and calcium source food and all animal food intakes were higher in the GID problem group. The results suggest that dietary behavior and food intake differ within the group of physical complaints.
