Purpose: This study examined the effects of a nutrition education program on self-efficacy, diet behavior pattern and cardiovascular risk factors for patients with cardiovascular disease (CVD). Method: Sixty-four CVD subjects (37 experimental, 27 control) were recruited from a cardiac center, at a university hospital located in D city, Korea. All subjects attended a first heart camp where pretest measures were performed, and a second heart camp at 6 months for the posttest measures. During the 6 month study period, the experimental group was required to attend five monthly nutrition education sessions, while the control group received only routine outpatient follow-ups. Data were analyzed by $x^2$-test and independent t-test using the SPSSWIN 11.5 program. Result: Group comparisons revealed that the experimental group had significantly more improved self-efficacy, frequency of food selection, gustation of salt, systolic blood pressure, and serum total-cholesterol compared to the control group. Conclusion: A nutrition education program may be effective in improving self-efficacy, diet behavior pattern and cardiovascular risk factors for patients with cardiovascular disease.

This study was conducted to investigate effects of nutrition education and exercise intervention on health and diet quality of middle-aged women. The subjects were 209 women who wanted to involve in the health promotion program run by Jincheon-Gun Health Center. Nutrition education was given once a week and dance sports were done twice a week for 3 months. Nutrient intakes were assessed by 24-hour recall method and food records. Dietary habits and nutrition knowledge were investigated by self-administered questionnaires before and after the intervention program. Body and blood compositions were measured before and after the program. The nutrient adequacy ratio (NAR) was significantly increased in energy, protein, vitamin A, vitamin B2 and calcium, mean adequacy ration (MAR) was significantly increased (p < 0.05), and also the index of nutritional quality (INQ) was significantly increased in protein (p < 0.01). Percent (%) RIs of protein (p < 0.01) and calcium (p < 0.05) were significantly increased and body weight (p < 0.001), body fat (p < 0.01), soft lean mass (p < 0.01) and BMI (p < 0.001) decreased. Over the 3-month study, there was a significant trend toward higher HDL-C and albumin levels and lower LDL-C level (p < 0.001). The results showed that nutrition education and exercise intervention could improve the body health and the diet quality.

The water striders, gerris paludum insularis larvae which were fed with the drosophila melanogaster cultured on the appli diet and artificial diet, were reared in the growth cabinet controlled as the two constant temperature regimes of 25 c and 30 c under the condition of photoperiod 16l : 8d, light intensity 510 240 lux, relative humidity 65 3%, and in the natural state. The effects of temperature and diet on the devolopment of g. paludum insularis were analyzed and the results were summarized as follows. 1. The total developmental period of the water strider larvae fed with the d. melanogaster reared on the apple diet at the natural stste was the longest 40 days, and the total devopmental periods at 25 c and 30 c were 35 days and 27 days respectively. The tolal developmental period of larvae fed with d. melanogaster reared on the artifical diet at 25 c was the longest 42 dats, and the total developmental periods at natural stste and 30 c were 32 days and 27 days, respectively. 2. In the larval developmental stages, the fifth stage was longer than that of any stage. The duration of egg stage which was not influenced by diet at 25 c was the longest. 3. The water strider larvae fed which the d. melanogaster reared on the artificial diet at 25 c did not complete their devolopment. 4. No significant difference was odserved in the developmentperiod for diet at 30 c. but, there were significant differences in developmental periods for diet at 25 c and natural state. 5. The rate of adult emergence on the apple diet was higher than that of the artificial diet was higher than of the artificial diet. 6. The shapes of the survivorship curve were convex-curve. 7. The development periods of the larval stages of water striders might be affected to temperature and diet dependently.

The number of patients is increasing and their mean age is also increasing. Proper dietary adjustments are necessary to prevent protein-calorie malnutrition or complications but it is difficult for dialysis patients to adapt to diet therapy due to stress or anorexia. Education does not consider the individual characteristics, knowledge, dietary inhabit education demands, and initial education. The purpose of this study was to identify dialysis patient's nutrition knowledge and, dietary practice and compare those with nutrition education or counseling demands for providing basic data of desirable nutrition management. The data were collected by a survey consisting of the general characteristics, disease related characteristics, nutrition education and counsel characteristics, level of nutrition knowledge, diet therapy, and nutrition education and counsel demands from the 28th March to 22th July 2017. The total number of subjects were 33 patients among dialysis patients at two tertiary medical institutions and an artificial kidney room at a private hospital in Incheon Gyeonggi. The data collected were analyzed statistically using the SPSS program 23.0, followed by further analyses using frequency analysis, one-way ANOVA, cross analysis, and correlation analysis. The results of the dialysis patients showed that younger (P<0.05), female (P<0.05), abnormal high school diploma (P<0.001) groups had high nutrition scores. In addition, dietary practice and nutrition education and counsel demands showed a positive correlation (P<0.05, P<0.01). In particular, females were higher than males in nutrition knowledge, dietary practice, nutrition education, and counseling demand scores.

This study investigated the general information, unbalanced diet, and dietary habits of 86 children in Daegu. The research was undertaken to analyze the current state of diet and dietary habits of children, and to provide basic data for nutrition education. The results reveal that younger children have a more unbalanced diet. Children dislike side-dishes the most. Furthermore, due to the longer time taken to consume food, parents persuade children to eat quickly. Children were also determined to have a high intake of foods and drinks containing sugar; beverages containing sugar are consumed 1-2 times a week by 5-year-olds, and once daily by 6- and 7-year-olds. The results of this study can be applied to provide basic data for nutritional education, and assist in the development of dietary programs for young children.

Objective: The objective of this experiment was to compare the effects of adding 130 mg/kg Cu from either copper sulfate (CS) or tribasic copper chloride (TBCC) on growth performance, mineral deposition in tissues, and the excretion in feces of pigs as well as changes in the mineral contents in tissues and feces when the supplemental Cu level was decreased from 130 mg/kg to 10 mg/kg. Methods: A total of 72 pigs ($32.6{\pm}1.2kg$) were randomly assigned to a CS diet or a TBCC diet with 6 pens per treatment. The trial lasted 102 d and included 3 phases (phase 1, 1 to 30 d; phase 2, 31 to 81 d; and phase 3, 82 to 102 d). The supplemental levels of Cu in the 2 treatments were 130 mg/kg in phase 1 and 2 and 10 mg/kg in phase 3. Results: The results showed that pigs fed the CS diet tended to have higher average daily gain than pigs fed the TBCC diet during d 1 to 81 (p<0.10). Compared with CS, TBCC increased the activities of aspartate transaminase (AST), ceruloplasmin, and superoxide dismutase in serum on d 30 (p<0.05). The TBCC decreased the Cu level in the liver on d 81 (p<0.05) and increased the Mn level in the liver on d 102 (p<0.05). The concentration of Cu in feces sharply decreased when the supplemental Cu level in diet changed from 130 mg/kg to 10 mg/kg in both diets (p<0.05). Conclusion: The result suggested that TBCC and CS had no significant difference on growth performance but TBCC had higher activities of AST and antioxidant enzymes and lower liver Cu than CS when pigs fed diets with 130 mg Cu /kg diet.

The purpose of this study was to evaluate the effectiveness of nutrition education and counseling on the salty taste assessment, nutrition knowledge and dietary attitude of 21 hemodialysis patients. Five times of the nutrition education and three times of nutrition counseling were performed for a period of 5 months. Biochemical analysis revealed that creatinine was significantly high (p < 0.001), blood urea nitrogen and serum albumin were significantly low (p < 0.05, p < 0.01) and Na, K, Cl, K, P and uric acid were not significantly different. The distribution rate of unsalty taste preference were significantly high and the distribution rate of salty taste preference were significantly low after nutrition education and counseling (p < 0.001). Nutrition knowledge significantly improved following 5th month of education and counseling (p < 0.01). Particularly, the scores for questions related to sodium were improved. The dietary attitude was significantly improved during the counseling period (p < 0.05). There were improvements in responses to 'use food exchange list on diet' and 'habitually add salt or soy sauce before the meal'. According to these results, salty taste assessment, nutrition knowledge and dietary attitude were significantly improved by the hemodialysis diet therapy practices of hemodialysis patients. Therefore, we conclude that there was a need for low-salt diet education and nutrition counseling to help them recognize the taste of low-salt foods and strive towards a preference for less salty tasting foods and the consumption of a low-salt diet.

The purpose of this study was to examine the effect of sociodemographic factors, BMI, self-esteem, body image, and external factors including parents, peers, and mass media on dieting behavior. The data were collected from 360 high school students in Gyeongbuk region. The respondents who have performed diet in the past or present were classified into the diet group. The students of diet group and non-diet group were 238 and 122, respectively. Frequencies, Cronbach's $\alpha$, t tests, and logistic regression analysis were carried out by SPSS Windows V.17.0. The results of this study were as follows. The diet group had higher level of BMI and concerns about diet than non-diet group. In addition, the diet group showed the more positive attitude about diet, and lower level of self-esteem and body image than the non-diet group. The diet group was more influenced by parents, peers, and mass media on body type than the non-diet group. Finally, according to the result of logistic regression analysis, BMI, attitude about diet, body image, effect of peers on body type, and effect of mass media on body type were significant factors to determine dieting behavior. These results imply that mass media should inform adolescents of proper body image and knowledge about diet. In addition, education for regular exercise also needs for healthy diet.

Purpose: It has been previously reported that breast tumor incidence, growth, and metastasis are stimulated by high-fat diet but reduced by caloric restriction. However, few studies have elucidated the effects of dietary change from a high-fat diet after breast cancer initiation. Therefore, in this study, we attempted to provide practical assistance to breast cancer prevention and management by investigating the effects of dietary change from a high-fat diet to normal diet on breast cancer growth and metastasis. Methods: The experimental animals were divided into 2 groups (high-fat diet control [HFC] group and diet restriction [DR] group) and consumed a high-fat diet for 8 weeks. 4T1 cells were transplanted into subcutaneous fat or tail vein to measure the growth and metastasis of breast cancer. The HFC and DR groups continuously ingested either high-fat diet or AIG-93G diet for 5 weeks or 3 weeks, respectively. Cell proliferation and apoptosis markers from tumor tissues were analyzed by Western blot analysis. The data were analyzed using the SPSS 25.0 package program. Results: The results show that the DR group significantly reduced breast tumor initiation, growth, and tumor tissue weight compared to the HFC group. The DR group suppressed tumor growth by decreasing proliferation and inducing apoptosis through down-regulation of Bcl-xL and up-regulation of caspase-3 activity. Furthermore, the DR group significantly reduced numbers of metastasized tumors in lung tissues. Conclusion: These results suggest that dietary change from a high-fat diet to normal diet decreased breast growth by reducing cell proliferation and inducing apoptosis and metastasis. Taken together, these results indicate that dietary change to a low-fat and balanced diet might suppress breast tumor growth and metastasis even after tumor diagnosis.
