This study aims to investigate both general dietary behaviors and clinical symptoms of diet related effects among fifth grade students at an elementary school in Ulsan Metropolitan City, and to categorize those relationships in terms of their comparative differences. The findings of this study are as follows. 1. Out of 694 students polled, 53.7% were of boys and 46.2% were girls with average age of $11.9{\pm}0.3$, average height of $145.1{\pm}6.8cm$, and average weight of $39.7{\pm}9.7kg$. Obesity in boys (5.5%) exceeded girls (3.9%) whereas children categorized as underweight showed girls (14.6%) slightly exceeded boys (10.4%). 2. Dietary behaviors were largely the result of four factors - unbalanced diet, balanced diet, protein and fruits and healthy dietary habits. Of these factors, protein and fruits ($4.04{\pm}1.03$) ranked first, balanced diet ($3.38{\pm}1.04$) second, healthy dietary habits ($3.04{\pm}1.01$) third and unbalanced diet ($2.23{\pm}0.6$) ranked last. 3. When Dietary behaviors were classified with four low ranking factors, they were divided into four types such as convenience (22.4%), good diet (24.7%), busy contemporary modern man (24.3%) and healthy dietary habits (26%). 4. Clinical symptoms include colds ($2.27{\pm}1.15$) followed by headaches ($2.17{\pm}1.19$), stomachaches ($2.16{\pm}1.15$), dizziness ($2.02{\pm}1.15$), atopic allergy ($1.95{\pm}1.30$), prevalence for cold sores ($1.86{\pm}1.07$), allergy ($1.65{\pm}1.05$), and constipation ($1.54{\pm}0.87$). 5. According to the results, clinical symptoms were divided into two groups - unhealthy (40.1%) and healthy (59.9%). 6. By analyzing the relationship between dietary behavior types and clinical symptom types, the convenience factor included slightly more of the unhealthy group (56.3%), whereas the good diet (71.1%), busy contemporary modern person (55.8%) and healthy dietary habits (69.7%) included more of healthy group (p<.001). Since the majority of students belonging to the unhealthy group had convenience dietary behavior, education about desirable dietary activities is needed for these students. In addition, nutrition information and information on possible clinical symptoms caused by nutritional imbalance should be provided for students and their households.

Hyperlipemia is the most leading risk factor of cardiovascular disease which is the main cause of death in Korea. However, there is a tendency to neglect the prevention and treatment since it has no specific symptoms. It has been reported that the level of serum-lipid can be lowered by the improvement of eating habits. Therefore, it is highly likely that the development of programs on the improvement of eating habits through behavioral theory is required to the community nursing practice. The theory of planned behavior, which assumes that human behaviors are determined by one's intention to carry out the behavior, can be characterized by the point that behaviors are not only individual factors but also social behaviors relating to subjective norms. It is widely recognized that this theory has a high predictability on health behavior due to it's simplicity clearness, and measurability as well as high quality of being general. Thus, the theory of planned behavior could be useful in developing a model of a health promotion program to the change of behaviors of the risk group of cardiovascular disease. Consequently, based on the theory of planned behavior, the purpose of this study is to develop an intention promotion program of the diet, and then to testify the effects. The sample of this study consisted of 26 industrial workers who had proved hyperlipemia from a medical examination in 1996 (experimental group 13, control group 13). The intention promotion program, which includes education, monitoring, pressure, counselling on the level of individuals, families and organizations, was conducted for 10 weeks The purpose of this program was to promoting intention of the diet through changes of the prerequisite factors of intention such as behavioral belief, outcome evaluation, normative belief and control belief. When it came to data analysis, the ${\chi}^2$-test and Fisher's Exact test were used to compare the general characteristics between the experimental and the control group, an independent t-test for the other variables. ANOVA was used to the test hypothesis, and the Pearson correlation test for variable's correlation. The results of this study can be summarized as follows ; 1) There was a significant increase in the intention(F=18.51, p=.00) of diet in the experimental group. 2) Diets(F=32.51, p=.001) in the experimental group were better carried out than in the control group. 5) There was a moderate correlation between the intention of diet and performance (r=.587. p=.003). From the results, it can be concluded that the intention promotion program is very effective, leading to the change of health promotion behavior. Above all, it is really valuable that the intention promotion program in this study regards health promotion behavior as a social behavior and that intervention was done on the level of family and organization. Consequently, when performing a health promotion program, social approach elevating the intention should go hand in hand in order to make the program effective.

Two calorimetric experiments were performed to investigate the effects of two diets with same concentrate: roughage ratio (70:30) but varying in composition on energy metabolism and methane production in faunated (F) and defaunated (DF) Muzaffarnagari sheep. For experiment I, ten animals were divided equally into two groups of which one was kept normally F as such while other was DF using 10% sodium lauryl sulphate. All the animals were offered diet I which comprised of oat hay and concentrate mixture I (CM I) containing maize grain (93%) as a major ingredient in 70:30 ratio. Similarly, the experiment II was conducted for which four F and four DF sheep (same as used for experiment I) were switched to diet II that consisted of maize hay and CM II (maize grain 59% + molasses 36%). Through diet II, DM intake in DF sheep was significantly (p<0.05) lower. Intake of GE through both the diets was similar in F and DF sheep. Digestibility of DM, OM, CP and GE and also metabolisability (ME/GE) was similar in F and DF sheep on both the diets. Total urinary energy loss did not differ in F and DF on both the diets, but methane energy loss as a percent of GE in DF was significantly (p<0.05) lower on diet I (3.75 vs 2.48), while it did not differ on diet II (3.20 vs 3.60). Heat production was significantly (p<0.01) reduced in DF on both the diets. Although, efficiency of utilisation of ME for maintenance calculated as per ARC (1984) did not differ in F and DF on both the diets, efficiency for maintenance and growth was higher (0.60 vs 0.672) on diet I in DF. It was inferred that methane production in DF sheep reduces on good quality hay-based diet supplemented with slowly fermentable carbohydrate (maize grain) but supplementation of molasses (rapidly fermentable CHO) nullify this effect when sheep were fed diets with concentrate: roughage ratio of 70:30.

Objectives: This study was performed to investigate the nutritional status, health conditions, eating habits and experience and demand for nutrition dietary management of senior citizens. And these data are formed foundation of development of nutrition dietary management education program and contents in welfare facilities for the aged. Methods: We visited 3 public health centers, 3 senior citizens centers, and 4 welfare centers in Seoul, Gyeonggi-do, Chungnam province, and Daejeon area and carried out interview by semi-structured questionnaire for senior citizens older than 65 years who use those facilities. Results: The study included 17%, 30.7% and 52.3% of senior citizens from public health centers, seniorcitizen centers and and welfare centers, respectively. The age range of 43.9% of the population was 65-74 years and and 56.1% were older than 75 years. We observed that 83.2% of subjects took some medicines due to diseases that they have and 58.0% took prescription medicines for hypertension. The thing that they considered the most when selecting food was 'the taste'(p<0.05). Regarding the level of practice to keep the dietary life, they answered more than 'average' for most of items but answered less than 'average' for lot of salt intake, drinking, exercise. For the experience of nutrition dietary life education, only 19.8% answered 'Yes' and the service for nutrition dietary life management showed the highest score in the demand for 'provide nutritious food'. For the size of consulting group for nutrition/dietary life education, the public health center and welfare center preferred a larger group size but the senior citizens center preferred a smaller group. With regard to who will carry out the consulting, the demand for dietitian was the highest and the operation type showed the high demand in the order of consulting, education. The contents that they want to have consultation in nutrition dietary life education were diet therapy for diseases and the ordinary diet therapy for health. Conclusions: This study suggested the management of nutrition dietry life necessitates qualitative measures according to the different types of welfare facilities. For these, it is in need of development of counseling and education program included therapy for disease. Above all, the policy to secure dietitian of welfare facilities for the aged to perform these should be achived.

This study sought to determine changes in self-selected diets in response to a high energy tomato pasta entree. Thirty men, mostly African-American, who were diagnosed with prostate cancer and also scheduled for prostatectomy were enrolled in the study. Dietary intakes were obtained by 24 hr diet recall for 3 days before the intervention and 3 days in week 2 during the intervention. Tomato pasta entrees were formulated to contain 30 mg of lycopene with roughly the same macronutrient composition and averaged 771 kcal/entree. Mean adherence to lycopene dose was 82% and, days when the entree was consumed, the mean adherence to lycopen was 90%. Lycopene intake in their self-selected diet decreased from 5 to 1 mg/day which lowered the exposure to lycopene, planned during the intervention. The men were able to decompensate for most of the added energy to their diet, but there was still a mean increase in total intake of 242 kcal/day (p=0.04), which did not result in weight gain over the short period of the study. There were no significant changes in the percent of energy from protein, fat or carbohydrates, but dietary cholesterol increased from 341 to 472 mg/day (p=0.0002). Mean intakes of vitamins A and C, and folate were not significantly different and were above the EAR. Vitamin E intake decreased, but, because of the variance in intake, the decrease was not statistically significant. Possible deterioration of diet quality should be a consideration when recommending whole food interventions for the prevention of chronic disease or the amelioration of physiological dysfunction.

The Korean society has gone through a dramatic change in its population, with rapidly increasing number of multicultural families through international marriages since 1990s. This study investigated the differences between multicultural families and Korean families in three areas related to dietary behaviors: diet-related behaviors and perception, and food preferences. A cross-sectional analysis was performed in 500 Koreans from Korean families and 104 couples from the multicultural families with Vietnamese wives. More subjects from multicultural families grew up in the countryside, received less education and also had lower income than the subjects from Korean families. Multicultural families ate traditional Korean meals more often at home and dined out less often than Korean families. The multicultural families focused more attention on nutritional aspects of their diets than Korean families. The Vietnamese wives in multicultural families favored Vietnamese foods but they rarely ate those foods in Korea despite an easy accessibility to Vietnamese ingredients. In conclusion, the multicultural families had more traditional Korean dietary patterns than Korean families, which could have been influenced by their socioeconomic factors. Further research with a quantitative analysis is needed in future studies to understand the effect of dietary patterns on nutritional status and quality of life in multicultural and Korean families.

The purpose of this study was to investigate the interests in food and nutrition information of internet users, and find the major problems associated with the use of internet information. Of 660 internet users, including 152 professionals, 127 white-collars, 130 college students, and 29 others, 66.4% had accessed the internet to obtain information. Of the subjects, 71% had used the internet to obtain nutrition information, 91.3% of which answered that they would keep using the internet for this purpose. The area of greatest interest and need of the professional users, in relation to nutrition information from the internet, was 'recipe and menu' (p<0.001). Whereas, the white-collars were most interested in nutrition information for 'diet for weight control' and 'diet'(p<0.001). Students were most interested in nutrition information related to 'diet' and 'diet for weight control'(p<0.001). Due to the variety of interests and applications of different users, there is a need to develop specialized nutrition information sites for internet users to easily obtain reliable and valuable information.

We examined the effects of selenium-binding peptide from sericin hydrolysates on the bioavailability of selenium-deficient rats. Three-week-old male rats were fed a selenium-deficient diet for 4 weeks while the normal control group was fed a normal diet. The selenium-deficient rats were divided into three groups: no treatment, organic selenium (OS), and inorganic selenium (IS). After selenium supplementation for 4 weeks, the level of serum glutathione reduced form in rats treated with organic selenium was significantly higher than that of inorganic selenium. Selenium retention rate also increased significantly in the organic selenium group compared to the inorganic selenium group [selenium deficient diet (DD)+OS 50.25% vs. DD+IS 17.04%, P<0.05]. In conclusion, binding of selenium to peptides from sericin hydrolysates seems to improve its bioavailability, and can hasten a cure for selenium deficiency in experimental rats.

Background: This study aimed to examine (1) the patterns of online health information search with respect to seeking and scanning, and (2) how online search, along with eHealth literacy, predicts perceived information usefulness in the context of diet and weight control. Methods: Online survey was conducted with 299 adults from the consumer panel recruited for the purpose of quality assessment of the Korean National Health Information Portal in 2016. We conducted paired sample t-test and multiple logistic regression to address the research questions. Data analysis was performed using IBM SPSS Statistics ver. 24.0 (IBM Corp., Armonk, NY, USA) and SAS ver. 9.3 (SAS Institute Inc., Cary, NC, USA). Results: Of the respondents, 38.8% were 'high seek-high scanners,' 35.8% were 'low seek-low scanners,' 13.0% were 'high seek-low scanners,' and 12.4% were 'low seek-high scanners.' eHealth literacy was a significant, positive predictor of online information scanning (odds ratio [OR], 2.46; 95% confidence interval [CI], 1.41-4.29), but not for online information seeking (OR, 1.75; 95% CI, 1.00-3.05). With respect to perceived usefulness of online information seeking, online seeking (OR, 4.90; 95% CI, 2.19-11.00) and eHealth literacy (OR, 2.30; 95% CI, 1.11-4.75) were significant predictors. Perceived usefulness of online scanning had a significant association with online scanning (OR, 2.38; 95% CI, 1.08-5.22), but not with eHealth literacy. Conclusion: To increase the effectiveness of the health policy for online information search and related outcomes in the context of diet and weight control, it is important to develop education programs promoting eHealth literacy.
