This quantitative study was conducted to examine the relationship between weight control behaviors and disordered eating patterns in some university students. This study used a cross-sectional study design. A total of 347 students from three universities participated in this study (88 male and 259 female) Eating disorders were assessed using the Eating Attitudes Test (EAT-26); a score of =20 identifies individuals who likely have an eating disorder, including anorexia nervosa and bulimia nervosa. A score for healthy dietary behaviors was obtained by self-assessment on a healthy diet scale (20-item questionnaire), and the severity of any state-trait anxiety was calculated by the state-trait anxiety inventory (40-item questionnaire). In the analyzed results, the percentage of participants with experience of weight control was 58% in male and 73% in female. The subjects with a high risk of an eating disorder (score of =20 of EAT-26) were 44.3% ($mean{\pm}S.D;\;18.9{\pm}13.4$) of the males, and 57.9% ($mean{\pm}S.D;\;23.2{\pm}11.6$) of the females. Higher Body Mass Index (BMI) was significantly related with an increased risk for an eating disorder in females, but not in males. In the group who had attempted weight control of all types, there was a severe risk of an eating disorder. Increased eating disorder risk was significantly related with weight control behaviors such as a higher number of attempts at weight control, having used medication, having experienced side effects, and having experienced disease for both sexes. Therefore, the results of this paper showed that detrimental behaviors of weight control are connected to an increased risk of eating disorders. Consequently, education regarding the correct, behaviors of weight control is necessary to prevent eating disorders in adolescents.

The objective of this study was to develop anti-browning agents for commercial ready-to-eat pear products, which are preferred not only to maintain the flavor, color and texture of pears, but also to increase consumers' preference. The sliced 'Shin-go (Niitaka)' pears were immersed in 5% and 10% oxidized starch, 1% citric acid, and 5% and 10% oxidized starch with addition of 0.1% sucralose for 3 minutes, and then they were packaged in vacuum sealed bags at $1^{\circ}C$ for 9 days. In order to evaluate the quality of packaged sliced pears, the quality index was determined in terms of color, firmness, soluble solids, and sensory quality. With the passage of storage time, no specific variation in firmness and soluble solids was observed. However, the ${\Delta}E$ value of the sliced pears treated with 5% oxidized starch solution was significantly lower than that of the other pears. Also, the Hunter L and b values of the sliced pears treated with 5% oxidized starch solution remained nearly constant from the beginning of storage. This observation shows that 5% oxidized starch solution was effective in reducing surface browning of sliced pears. Moreover, sliced pears treated with oxidized starch solution with addition of 0.1% sucralose were given an overall liking score which was slightly higher than that given to the other pears because of the sweetness of sucralose. In conclusion, 5% oxidized starch solution with addition of 0.1% sucralose was effective in reducing browning of sliced pears and in improving the taste of sliced pears.

This study was conducted to investigate the consumption practices of ready-to-eat (RTE) foods and to analyze the microbiological hazard of kimbab, a Korean dish, and the most popular of the RTE foods eaten by participants in this study. A questionnaire was distributed to 230 university students who had previously purchased RTE foods, and 224 were collected (response rate: 97.4%). Statistical analyses were conducted on the questionnaires using the SPSS program, and a total of 135 kimbab products were sampled for aerobic plate counts, coliforms, E. coli, E. coli O157:H7, Staphylococcus aureus, Salmonella spp., and Listeria monocytogenes. The results of the analyses are as follows. Kimbab (87.0%), sandwich (86.4%), hamburger (89.8%), lunchbox (81.5%), and sushi (87.4%) were most often eaten immediately after purchasing. Additionally, the results of the microbiological hazards analysis of kimbab showed that the aerobic plate counts were significantly different according to the purchasing price (p<0.01). The coliform levels were significantly different according to the place of purchase (p<0.01) and the major ingredients of kimbab (p<0.05). In addition, Staphylococcus aureus and E. coli were detected in 5.9% and 5.2% of the tested samples, respectively. However, E. coli O157:H7, Salmonella spp., and Listeria monocytogenes were not detected in any of the samples. In conclusion, the manufacturers of RTE foods should apply the HACCP system for food safety.

BACKGROUND/OBJECTIVES: Abundant consumption of seaweeds in the diet is epidemiologically linked to the reduction in risk of developing cancer. In larger cases, however, identification of particular seaweeds that are accountable for these effects is still lacking, hindering the recognition of competent dietary-based chemo preventive approaches. The aim of this research was to establish the antiproliferative potency and angiosuppressive mode of action of Stoechospermum marginatum seaweed methanolic extract using various experimental models. MATERIALS/METHODS: Among the 15 seaweeds screened for antiproliferative activity against Ehrlich ascites tumor (EAT) cell line, Stoechospermum marginatum extract (SME) was found to be the most promising. Therefore, it was further investigated for its anti-proliferative activity in-vitro against choriocarcinoma (BeWo) and non-transformed Human embryonic kidney (HEK 293) cells, and for its anti-migratory/tube formation activity against HUVEC cells in-vitro. Subsequently, the angiosuppressive activity of S. marginatum was established by inhibition of angiogenesis in in-vivo (peritoneal angiogenesis and chorioallantoic membrane assay) and ex-vivo (rat cornea assay) models. RESULTS: Most brown seaweed extracts inhibited the proliferation of EAT cells, while green and red seaweed extracts were much less effective. According to the results, SME selectively inhibited proliferation of BeWo cells in-vitro in a dose-dependent manner, but had a lesser effect on HEK 293 cells. SME also suppressed the migration and tube formation of HUVEC cells in-vitro. In addition, SME was able to suppress VEGF-induced angiogenesis in the chorio allantoic membrane, rat cornea, and tumor induced angiogenesis in the peritoneum of EAT bearing mice. A decrease in the microvessel density count and CD31 antigen staining of treated mice peritoneum provided further evidence of its angiosuppressive activity. CONCLUSIONS: Altogether, the data underline that VEGF mediated angiogenesis is the target for the angiosuppressive action of SME and could potentially be useful in cancer prevention or treatment involving stimulated angiogenesis.

The farmers' nutritional condition can not be compared with other citizens according to the Korean National Health & Nutrition Examination Survey, and based on other literature reviews. These farmers have either less access to educational materials or have no idea and do not understand the importance of nutritional education. The purpose of this study is to develop an appropriate reading material on nutrition to educate the farmers. To do this, the first step was to gather sufficient available materials for the review of related literature. Second, a survey was conducted to assess the needs of farmers and extension workers for educational materials on nutrition. The results showed that the farmers preferred the following topics: Menu Planning or Menu for Health' (62.1%), Dietary Assessment (49.7%), Dietary Guideline for Farmers (35.7%), and Cooking Method and Recipe (32.6%). They also preferred the booklet type (62.7%). These materials basically contained literature review, lesson plan, and needs assessment. The booklets contained in detail: 1) Dietary assessment - nutritional assessment, and assessment of meal 2) Dietary guidelines for farmers - reduce salt intakes, eat calcium-rich foods, ideal body weight, reduce alcohol-drinking and smoking, tips on eating soybean, eat meat and fish, tips on eating fruits, eat shellfish and seaweeds, and tips on eating dietary fibers, and 3) Plan a meal - menu planning and sample menu by farming patterns. Finally, the text of the final material was improved by the graphic designer using Quark Express 3.3, Photoshop 6.0, Illustrator 10.0, and Painter 8.0. The booklet has 46 pages and divided into three chapters. This contains simple and affordable recipes and provides some helpful tips for dietary and changing lifestyles. This booklet is made available for farmers and other groups interested in nutrition education.

This study was conducted to investigate the degree of practice of dietary behavior and dining out in accordance with intake of sodium among male and female adults aged 20 years or older residing in the Seoul Metropolitan area or Chungcheong Province. A total of 530 copies of the questionnaire were distributed from May to July, 2014. The SH group who responded that they eat a lot of sodium constituted 30.6% (158 people), followed by the SM group who responded that their sodium intake is about average at 55.7% (288 people) and the SL group who answered that they do not eat much sodium at 13.7% (71 people). Those in the SL group showed positive results for dietary behavior patterns. The SL group showed the lowest rate in terms of how often they eat harmful foods, including processed foods, sweet foods, salty foods, or food with high animal fat content such as pork belly. Positive results among the SL group were prominent in terms of avoiding over-drinking, regular exercise, and nutritional knowledge, indicating greater health management. The distribution of each group in terms of self-perceived sodium intake showed significant differences across age, gender, and household income in terms of frequency of fast food intake, regularity of meals, purchase of foods with consideration of sodium amount, frequency of missed meals, balance of food intake, and health management habits.

The consumption of poultry meat (chicken and turkey) grew the most during the past few decades due to several contributing factors such as low price, product research and development, favorable meat characteristics, responsive to consumer needs, vertical integration and industry consolidation, new processing equipments and technology, and aggressive marketing. The major processing technologies developed and used in chicken processing include forming/restructuring, tumbling, curing, smoking, massaging, injection, marination, emulsifying, breading, battering, shredding, dicing, and individual quick freezing. These processing technologies were applied to various parts of chicken including whole carcass. Product developments using breast, thigh, and mechanically separated chicken meat greatly increased the utilization of poultry meat. Chicken breast became the symbol of healthy food, which made chicken meat as the most frequent menu items in restaurants. However, the use of and product development for dark meat, which includes thigh, drum, and chicken wings were rather limited due to comparatively high fat content in dark meat. Majority of chicken are currently sold as further processed ready-to-cook or ready-to-eat forms. Major quality issues in chicken meat include pink color problems in uncured cooked breast, lipid oxidation and off-flavor, tenderness PSE breast, and food safety. Research and development to ensure the safety and quality of raw and cooked chicken meat using new processing technologies will be the major issues in the future as they are now. Especially, the application of irradiation in raw and cooked chicken meat products will be increased dramatically within next 5 years. The market share of ready-to-eat cooked meat products will be increased. More portion controlled finished products, dark meat products, and organic and ethnic products with various packaging approaches will also be introduced.

This survey was carried out to Investigate the effects of dietary attitude on the nutrition knowledge, food habits, the daily average nutrient Intakes and the intake of Instant food, convenience food & fast food between college women and their mothers. Questionnaires were completed by 214 college nutrition majors and also by their mothers numbering at 173. College women's mothers showed a better average in meal time regularities per week than that of. college women. Also it is the fact that the college women had a higher frequency rate of instant food and fast food than their mothers. In the case of both college women and mothers if they eat at regular meal times they had a higher score in food habits. But the daily average nutrient intakes was not significant because of the fact that the meal time regularity and nutrient intakes 414 not concise. The higher frequency of instant food intake had a lower score in food habits and nutrition knowledge. The higher frequency of fast food Intake had a higher food habits score but it also had a lower score in nutrition knowledge. As in the intake of instant food and convenience food the college women had a higher Intake frequency. In the dietary pattern the college women they liked to eat (lour foods. But their mothers liked to eat Korean foods. The selective motive and the degree of satisfaction of food service industry product was for convenience and time saving. The food service industry products were found to be unsatisfactory in nutrition and sanitation. Therefore we must be more aware of preventing the disappearance of Korean traditional foods. For the continuing development of our dietary culture we need to have the food service industry to develop more suitable diet for Korean.

As Korea has approached the aging society, older Koreans have become an important force in restaurant sales today. To succeed with this silver market, it is important for restaurant managers to know who they are and which factor influence the older Koreans' eating-out decision making process. The purpose of this study was to investigate the effect of the elderly consumers financial independency on restaurant selection process. Data were collected from 178 older consumers above 55 years old and analyzed using the descriptive statistic analysis, MANOVA, and one-way ANOVA. The results showed that the elderly consumers financial independency significantly influenced the decision making process in determining where they eat out Significant differences were found between high income group and low income group in the Problem Recognition Step(Wilks' Lambda=0.776, F=3.796), Information Search Step(Wilks' Lambda=0.779, F=2.959), Alternative Evaluation Step (I :Wilks' Lambda=0.835, F=1.748/ II :Wilks' Lambda=0.764, F=3.212), and Purchase Decision Step(Wilks' Lambda=0.849, F=2.412), except the Post-Purchase Behavior(Wilks' Lambda=0.933, F=1.179). The more financially independent older consumers were, the more directly they were involved in the eating out decision making process. Older consumers with higher income and more personal property were likely to 'propose to eat out by themselves'(F=10.986), to obtain restaurant information from the 'printed materials'(F=9.707), to consider 'convenient location' as most important factor when they eat out(F=5.594), and to go to 'family restaurant'(F=7.067), 'Japanese restaurant'(F=7.391) and 'fine dining restaurants'(F-=6.382). In conclusion, we found that the elderly consumers financial independency did influence the eating-out decision making process. Considering that older Korean will become a financially independent consumer and will be eating away from home more often, food service operations should actively position themselves for this market and develop the market-driven menus and services to meet their needs and expectations.
