The purpose of this study was to analyze information about food and nutrition topics presented throughout the television broadcast media, thereby find out the optimal communication method to give desirable information to the general public. To perform this study were recruited and trained by monitoring education before and during the study. 3 domestic TV channels were selected to be monitored, for 3 months. Results of this study were as follows: First, the total reporting cases of information about foods and nutrition were 154, When each monitored contents was seen from the domain of programs, 128 cases(83.1%) were from current affairs and information program, and 26(16.9%) were from entertainment program. Second, according to survey by channel cases are 26(16.9%) from KBS, 54 cases(35.1%) from MBC, 74 cases(48.1%) from SBS, which means SBS reported the most about nutritional foods. Third, the frequency of reporting information on the overall diet and food & ingredient, cuisine & cookey, health & diet therapy and obesity & diet in order. Forth, among the 26 cases of positive or negative implications made by each cannel of KBS, 18 cases were delivered in positive ways, 7 cases had positive and negative point of views mix together, and 1 cases was negatively delivered. Finally, the most important thing is to organiae the advisory team by connecting mass media and specialist, and the educational program of nutrition should be developed for the communication of right information about foods and nutrition.

The carcass traits and meat quality of Hanwoo (Korean native cattle) whose diets were supplemented with direct-fed microbial (DFM) and pine cone extract (PCE) were evaluated. Twenty head of Hanwoo steers were divided equally into four groups and for a period of 6 months were given different diets: One group was fed a basal diet as control (CON), the other three groups were fed a basal diet supplemented with DFM-1%, DFM+PCE-1% and DFM+PEC-3%, respectively. DFM+PCE3% diet resulted the lowest carcass quality grade. The loins of DFM-1% contained higher moisture and lower fat than did the loins from the CON group. The crude protein content of DFM+PCE-3% group was significantly higher than that of the other groups. The water holding capacity and Warner-Bratzler shear force of the DFM+PCE-1% and 3% groups were lower than those of the CON and DFM-1% groups. The DFM-1% and 3% groups contained lower saturated fatty acid, higher unsaturated fatty acid, mono-unsaturated fatty acid, and poly-unsaturated fatty acid than did CON and DFM+PCE 1% group. Moreover, the n6:n3 ratios of DFM-1% and DFM+PCE-1% and 3% groups were slightly lower than that of the CON group. Thus we concluded that DFM and PCE supplementation resulted healthier Hanwoo beef with lower fat content and n6:n3 ratio.

The current study investigated the anti-obesity effect of Cissus quadrangularsis extracts (CQR-300) and its molecular action mechanism on obese mice induced high-fat diet (HFD). To induce the obesity, mice were fed a HFD for 6 weeks and then fed HFD only or HFD with CQR-300 at 50 and 200 mg/kg. Then, body weight gain and white adipose tissue weights were measured. We investigated the reduction in body fat and the regulation of fatty acid synthesis was measured by dual energy X-ray absorptiometry and real-time PCR with Western blot, respectively. In vitro study, CQR-300 inhibited pancreatic lipase activity. The CQR-300 treatment was significantly decreased the body weight gain and adipocytes size as well as white adipose tissues weights in HFD-induced obese mice. Furthermore, CQR-300 reduced the body fat and fat mass with regulating of adipose tissue hormones as leptin. Treatment with 50 mg/kg CQR-300 showed effectively lower expression levels of adipogenesis/lipogenesis related genes and proteins such as CCAAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$), peroxisome proliferator-activated receptor ${\gamma}$ ($PPAR{\gamma}$), Sterol regulatory element binding protein-1c (SREBP-1c), and fatty acid synthase (FAS) in white adipose tissue (WAT) as compared with the HFD fed only mice. These results suggest that the CQR-300 has an anti-obesity effect via inhibition of lipase activity, decrease the body fat mass by regulating the adipogenesis and lipogenesis related genes and proteins in epididymal adipose tissue with evaluate body fat reduce in the HFD-induced obese mice.

The purpose of this study was to investigate the effect of 3-month nutrition education (First Time Intervention, FI) + additional 3-month nutrition education (Repeated Intervention, RI) which was performed after the 8-month followup. FI was conducted during 0-3 months and RI for 11-14 months. Ninety-two subjects completed FI program, and 38 out of 92 subjects who received FI finished the RI. Anthropometric data, dietary assessment (24hr recall) and fasting blood analysis were measured at 0 month, 3 months, 11 months and 14 months time points. After FI (3 mo), waist circumference, triglycerides, total cholesterol were significantly decreased. At 11 month follow-up, body weight, BMI, hip circumference, SBP, DBP were significantly rebounced and HDL cholesterol was significantly decreased. Therefore, the effect of short-term nutrition education was not being sustained. After the secondary nutrition intervention (14 mo), waist circumference and hip circumference were again significantly decreased. Total diet quality index-international (DQI-I) score was significantly increased in both FI group and RI group. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.129, p < 0.05) and counts of nutrition education (r = 0.159, p < 0.05), indicating that effective nutrition education helps improve the diet quality leading to a possible role in CVD prevention among male workers. Although a short-term intervention seems to be a success, the effect was not retained in this study. Therefore, we suggest incorporating nutrition education as a routine program for male worker at worksite.

The purpose of this study was to examine the effect of temple food intake on health improvement. The survey was conducted from September to October 2013. The subjects in this study were 46 adults who participated in short-term 'Temple Stay' program. Every meal was prepared according to prearranged temple food menu, and it was provided to subjects for 4 weeks. Dietary intake, anthropometric measurements and biochemical parameter were measured and nutritional & health status were analyzed to find the effect of the program. Nutrients content of the temple food was sufficient to dietary reference intake while content of fat, fiber, vitamin A and calcium from the meal was significantly higher than the subjects' usual diet. Mean body weight, BMI and blood pressure (systolic and diastolic) related with obesity and hypertension decreased after the program. The index referring to liver function and cardiovascular disease risk such as serum ALT, ${\gamma}$-GTP, TG and LDL decreased while HDL increased thereby showing positive effect. The above results anticipate that temple foods with an affirmative effect in improving health status have a potential benefit that can be applied to general food service. Further detailed study might provide information in developing healthy diet for a corresponding clinical problem.

Purpose: This study was aimed to investigate the effects of the nutritional intervention program including DASH diet education and calcium/vitamin D supplements in Korean elderly women. Methods: This was a quasi-experimental study employing non-equivalent control group pretest-posttest design. The experimental group (n=26) was given DASH diet education and supplements (calcium 1200mg and vitamin 800 IU) while the control group (n=16) was given only general health consults. After the interventions, differences were analyzed in nutrient intake, bone turnover markers and bone mineral density between the two groups. Results: After one year, bone mineral density was found reduced in both groups, but showed higher levels (p=.003) in the experimental group than the control group. After research, nutrient intakes of participants improved generally, yet there was no significant difference between the two groups. The experimental group was divided into subgroups after interventions according to the level of calcium intake, and bone density and bone markers were compared between the subgroups. In a subgroup whose calcium intake was in the normal range, bone mineral density was significantly high (p=.002) while CTx and osteocalcin were significantly low (p=.003, p=.006, respectively). Conclusion: This study is significant in that it provided a nutritional intervention program for one year to elderly women who are susceptible to osteoporosis and severely low in dietary calcium intake and it proved to be effective.

Diet attrition and failure of long term treatment are very frequent in obese patients. This study aimed to identify pre-treatment variables determining dropout and to customise the characteristics of those most likely to abandon the program before treatment, thus making it possible to modify the therapy to increase compliance. A total of 146 outpatients were consecutively enrolled; 73 patients followed a prescriptive diet while 73 followed a novel brief group Cognitive Behavioural Treatment (CBT) in addition to prescriptive diet. The two interventions lasted for six months. Anthropometric, demographic, psychological parameters and feeding behaviour were assessed, the last two with the Italian instrument VCAO Ansisa; than, a semi-structured interview was performed on motivation to lose weight. To identify the baseline dropout risk factors among these parameters, univariate and multivariate logistic models were used. Comparison of the results in the two different treatments showed a higher attrition rate in CBT group, despite no statistically significant difference between the two treatment arms (P = 0.127). Dropout patients did not differ significantly from those who did not dropout with regards to sex, age, Body Mass Index (BMI), history of cycling, education, work and marriage. Regardless of weight loss, the most important factor that determines the dropout appears to be a high level of stress revealed by General Health Questionnaire-28 items (GHQ-28) score within VCAO test. The identification of hindering factors during the assessment is fundamental to reduce the dropout risk. For subjects at risk, it would be useful to dedicate a stress management program before beginning a dietary restriction.

BACKGROUND/OBJECTIVES: Most child and adolescent food literacy measurement tools focus on nutrition and food safety. However, the importance of aspects related to the food system such as food distribution and food waste and their effects on environmental sustainability is growing. We therefore developed and validated a two-dimensional tool for children (8-12 years old) and adolescents (13-18 years old) that can comprehensively measure food literacy. The association of food literacy with diet quality and self-reported health was assessed. SUBJECTS/METHODS: First, we developed a food literacy conceptual framework that contains food system and literacy dimensions through a literature review, focus group interviews, and expert review. After a face validity study, we conducted the main survey (n = 200) to validate the questionnaire. Construct validity and reliability were assessed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Cronbach's alpha. RESULTS: As a result of the Delphi study, content validity was confirmed for the remaining 30 items after two items were excluded (content validity ratio = 0.86). Eleven items were excluded from the EFA results, while the CFA results indicated appropriate fit indices for the proposed model (comparative fit index = 0.904, root mean square error of approximation = 0.068). The final food literacy questionnaire consisted of 19 questions and comprised 5 factors: production, distribution, selection, preparation and cooking, and intake. Food literacy was positively associated with diet quality, as assessed by the Nutrition Quotient score, in both children and adolescents and with self-reported health in adolescents.

A feeding trial was conducted to investigate the effect of skip-a-day feeding program in early growing stage of male broiler chicks on the compensatory growth, and development of visceral organs during the later realimentation period. Day-old 328 male broiler chickens( Avian x Avian) were divided into control(ad libitum feeding) and skip-a-day feeding(limited feeding) treatments. Each treatment was consisted of 4 pens( replicates) of 41 birds each. Chickens on the skip-a-day program were fasted every other day during the second wk of age(8~15 d of age). During the starter period(0~4 wk), chickens were fed a commercial crumble diet. A commercial pellet diet was fed to chickens during the finishing period( 5~8 wk). Chickens were group-weighed every week, and one bird was selected from each pen to measure carcass characteristics. The skip-a-day program delayed the growth rate of male broilers up to 4 wk of age(P

Purpose: The purpose of this study was to investigate the effects of an intensive teaching program on the knowledge level of MI in patients with a myocardial infarction. Method: The subjects were 47 patients with a myocardial infarction. Of the subjects 23 were assigned to the experimental group and 24 to the control group. The data were collected through a questionnaire (Lee, 1992; Nam, 1998) survey of knowledge level. The data collection was done about MI between September 15, 1999 and December 31, 2000 after hospital discharge. Data were analyzed using the SAS program and the results are as follows. Results: 1. There were no significant difference in knowledge level of the MI (P=0.621) between the two groups before the teaching program was given. 2. After 4 weeks the knowledge level about MI was significantly higher in the experimental group compared to the control group (P = 0.000). 3. After 12 weeks the knowledge level about MI was significantly higher in the experimental group compared to the control group (P= 0.000). 4. After 4 weeks the experimental group was at a higher scores of knowledge category about MI for nature of disease (P=0.000). risk factors, (P=0.000), diet (P=0.000), medication (P=0.000) exercise and daily activities (P=0.000) as compared to the control group. 5. After 12 weeks the experimental group was at a higher scores of knowledge category about MI for nature of disease (P=0.000). risk factors (P=0.001). diet (P=0.000), medication (P=0.000) exercise and daily activities (P=0.000) as compared to the control group. Conclusion: The above findings indicate that the intensive teaching program used for the experimental group in this study was effective in increasing the knowledge level about MI of the patients with a myocardial infarction.
