Hospital malnutrition could be caused by not completing the food served in the hospital. This has been a big problem since it delays the recovery of the patient and extends the length of hospital stay. The purpose of the study was to reduce the plate waste for the DM diet by performing several nutrition service improvement activities. The study was performed in a general hospital with 900 beds. A questionnaire survey was taken by 39 DM patients to obtain their aspect of the hospital foodservice systems and the quality of the meals at the beginning of the study. The amounts of foods served in the hospital kitchen and returned were measured by weights. After the improvement activities, the measurement of the plate waste was performed again for comparison. The average percentage of plate waste for the DM diet was 23.2%. The survey showed no difference by sex, age or duration of admission in plate waste. However, this food wastage percentage showed differences between the patients having a chance to get information about the diet therapy (12.21%) and not having one (26.06%) (p < 0.05). Using a five-point Likert-type scale, the quality of food by its taste was 2.49 (1: very poor, 5: excellent), the temperature score was 3.56 (1: very poor, 5: excellent), and the amount of food served score was 2.95 (1: very poor, 5: excellent), and the preference score was 3.13 (1: very dislike, 5: very like). Nutritional care improving activities were performed by adjusting seasonings, developing new menus, and standardizing cooking methods in order to increase the satisfaction of meal quality. The dietitian's inpatients care protocol was adjusted to expand the nutritional counseling chance for the DM patients. After the improvement activities, the average plate waste was reduced to 14.6%, and the satisfaction of food taste and preference increased to 3.21 (p < 0.001), and 3.36 (p < 0.05) correspondingly. The result shows that, for therapeutic diet patients, food intake could be increased by improving the food service satisfaction by controlling the meal quality and clinical nutritional service activities.
This study was conducted to investigate Korean youths' use of fastfood and family restaurants in different regions, especially among cities and rural towns. Total 1,600 questionnaire surveys were distributed to Junior high and Senior high school students and 1,487 were used for the analysis. In order to consider regional differences as well as overall characteristics of youths' fastfood and family restaurant visiting behaviors, the subjects were evenly sampled from north Seoul, south Seoul, big cities, middle/small cities and small towns. As for the frequency of visiting fastfood restaurants, 58.3% of the respondents answered 'once to five times' a week. South Seoul area showed the highest frequency. 'Easiness' was the main reason of eating fastfood, which was up to 57.8% of the overall respondents while 42.8% of the small town youth ate fastfood because of the 'good taste.' As for the concepts on fastfood, 42.7% understood it as 'easy to eat' while 33.6% responded as 'easy to get fat.' For the question of getting channel of fastfood information, 44.8% answered 'TV' and 28.3% responded 'from friends.' Coupons were found to affect fastfood restaurant visits, highest in south Seoul, and lowest in small cities. For the question of the relationship of Koreanized menus and fastfood restaurant visits, small towns showed the highest frequency, while South/North Seoul had the lowest frequency. For the percentage of visiting family restaurants, respondents answered in the order of South Seoul(59.7%), North Seoul(44.5%), Big cities(39.5%), small cities(19.4%), and small towns(13.1%). Most of youth visited family restaurants because of the taste, while youths of middle/small cities visited due to the atmosphere. The effect of coupons on visiting family restaurants were found to be lower than the one of fastfood restaurants. Korean youths were found to visit fastfood restaurants very frequently in all regions and the tendency of visiting family restaurants is also increasing. At this point, balanced menus and education for healthy eating habits are urgently needed for the youth.
Dietary therapy is a basic and emphasized treatment for diabetes. Several clinical studies have shown that diet can play a major role in preventing and managing diabetes. The purposes of this study were to evaluate the dietary behavior and to find solutions to barriers of diabetes mellitus patients. From February to July in 2007, questionnaires were distributed to one hundred and ten patients who were diagnosed DM by physicians and excluded first coming out-patients. One hundred and three data were used for statistical analysis using SPSS/Win 12.0. The main results of this study included the following: To measure dietary behaviors and barriers, a five point scale was used with the following labels: 'strongly yes', 'yes', 'fair', 'no', 'strongly no'. Thirteen dietary behaviors related to diabetes were grouped into the following 4 factors using factor analysis; 'taste control factor', 'blood glucose influence factor', 'practice volition factor', and 'exercise factor'. The mean scores of 4 factors were 3.88, 3.48, 3.55, 3.21, respectively. The 'taste control behaviors' score of subjects who had practiced diet therapy(4.00) was higher than those who had not practiced diet therapy(P<0.05). The 'blood glucose influence behaviors' score of subjects who had nutrition education(3.59) was higher than those who had no nutrition education(P<0.05) and subjects who had practiced diet therapy showed higher score(3.59) than those who had not practiced diet therapy(P<0.05). 'Exercise behaviors score' of subjects who were over 60(3.59) was the lowest(P<0.05). Subjects who had nutrition education showed higher 'exercise behaviors' scores(3.38) than those who had no nutrition education(P<0.05). Subjects who had practiced diet therapy showed higher 'practice volition behaviors' scores(3.72) than those who had not practiced diet therapy(P<0.001). Subjects who were over weight showed the highest 'practice volition behaviors' scores(3.78) concerning BMI(P<0.05). In conclusion, this study expected that Nutrition educators(Dietitian) applied to patient effective nutrition education and counseling through evaluation of Dietary behaviors and barriers considered management types and ecological factors of diabetes patients. Also diabetic patients were easy to change dietary habits because they formed behaviors through education and counsel and there were positive effects in their blood glucose control through removing barriers related to dietary therapy.

High intakes of sodium may increase the risk of hypertension or cardiovascular diseases. According to the 2010 Korea National Health and Nutrition Survey, the average intake of sodium was 4,878 mg/day with salt, kimchi, soy sauce, fermented soybean paste and Ramyeon being the five main sources of sodium. In order to identify solutions to reduce the intake of sodium, we investigated the intake patterns and eating behaviors of Ramyeon among 347 college students (male 146, female 201) using survey questionnaires. The average age of study subjects was 23.7 years for males and 20.5 years for females. The average Body Mass Index ($kg/m^2$) was 21.9 for males and 20.1 for females. The average frequency of Ramyeon intake was 2.0 times/week. The main reason for eating Ramyeon was convenience (56%), followed by good taste (27%), low price (11%) and other reasons (9%). The criteria for choosing Ramyeon were taste (72%), convenience (14%), price (7%), nutrition (1%), and the other factors (2%). Males' average intake of Ramyeon soup (61%) was higher than that of the females (36%). The estimated intake of Ramyeon soup by survey showed a positive correlation with the measured intake of Ramyeon soup. Sodium contents of Ramyeon were measured separately for the noodles and the soup, which were 1,185 mg/serving and 1,148 mg/serving each. Therefore, the amount of sodium intake can be reduced if students eat less Ramyeon soup. Also, we observed that dietary behaviors and soup intakes of Ramyeon between the sexes were different. Appropriate nutritional education for proper eating habits may help decrease the intake of sodium.
In order to establish the processing condition of rapid- and low salt-fermented liquefaction of anchovy (Engrulis japonica), effect of temperature on crude enzyme activity of anchovy viscera, pretreatment conditions, and the minimum content of adding NaCl were investigated. The minimum limitation of NaCl content for anchovy liquefaction was 10%. Sample A(water adding, heating, adding 10% NaCl): chopped whole anchovy adding 20% water and then heating for 9 hrs at $50^{\circ}C$ and then adding 10% NaCl and then fermented at room temperature$(8-29^{\circ}C)$ for 180 days. Sample B(water adding, heating, adding 13% NaCl): chopped whole anchovy adding 20% water and then heating for 9 hrs at $50^{\circ}C$ and then adding 13% NaCl and then fermented at room temperature for 180 days. Sample C(adding 13% NaCl): chopped whole anchovy and then adding 13% NaCl and then fermented at room temperature for 180 days. Sample D(adding 17% NaCl): whole anchovy adding 17% NaCl and then fermented at room temperature for 180 days. The content of free amino acids such as aspartic acid, serine and threonine fluctuated severely according to the pretreatment methods. Possibly they might be recommend quality indices of standardization for salt-fermented liquefaction of anchovy. As for the relation between fermentation period(X) and individual free amino acid(Y), five kinds of free amino acids such as glutamic acid, valine, glycine, lysine, and alanine showed highly significant in their coefficient of determination in most of samples. They might be recommend as quality indices for salt-fermented liquefaction of anchovy during fermentation. The difference of taste between products of the rapid- and low salt-fermented liquefaction and the traditional salt-fermented liquefaction were caused by their composition of the free amino acids ratios, in which were umami, sweet, and bitter taste in the extracts of anchovy during fermentation. The appropriate fermentation period of the sample A was shorten 30 days than the sample B and 60 days than the samples C and 90 days than the sample D in the processing of anchovy.

Yacon (Smallanthus sonchifolius) contains high amounts of fructooligosaccharides and has been known to promote health of the intestinal tract and to have anti-oxidative and anti-cancer activities. Yacon concentrates were added to make five different pan breads, each with the addition 0% (YE 0), 25% (YE 25), 50% (YE 50), 75% (YE 75), and 100% (YE 100) of yacon concentrates instead of sugar. The higher the yacon concentration in the dough, the more time was needed for the dough to rise. Higher yacon concentration also affected the color of the bread by lowering the L-value and raising the a and b values. The hardness and chewiness of the bread significantly decreased with increasing yacon concentration, while cohesiveness increased. In the bread sensory evaluation, the intensity of crust color, crumb color, yacon flavor, sweetness, yacon taste, moistness, and residual mouth feel were increased with increasing yacon concentrates, while the uniformity of crumb pores slightly decreased. The consumer acceptance of taste, flavor, texture, and overall acceptance were increased with increasing yacon concentrations. As a conclusion, the substitution of yacon concentrates for sugar improved bread quality and increased consumer acceptance.
This study was conducted by empirically analyzing the relation between effects of positive emotional response of female customers, who have at some point consumed food at Korean restaurants in Busan, and behavioral intention according to their food service consumption propensity. In order to achieve the objective of the study, the questionnaire survey was performed from March $10^{th}$ to $25^{th}$, and frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and SEM (structure equation model) were conducted by using SPSS 18.0 and AMOS for 248 questionnaires. As a result of an exploratory factor analysis, five factors were confirmed. In a confirmatory factor analysis, the average variance extracted (AVE) and composite reliability (CR) were confirmed as .508 to .665 and .905 to .946 respectively, which proved the convergent validity. In a hypothesis test, Hypothesis 1 was determined that the food service consumption propensity positively effects on emotional response. The results were as follows: the taste driven (${\beta}$=.325, t=3.907, p<.001), the health driven (${\beta}$=.190, t=2.688, p<.001), and the atmosphere driven (${\beta}$=.188, t=2.515, p<.001). Therefore, Hypothesis 1 was selected. Hypothesis 1 has determined that positive emotional response beneficially affects behavioral intention. As a result of an analysis, the standardized path coefficient was (${\beta}$=.496, t=6.388, p<.001), so Hypothesis 1 was selected. This result suggests that the taste driven factor has the biggest influence on emotional response in the food service consumption propensity for female customers, and food service business operators should strive to make a good restaurant atmosphere for customers to get positive emotional response (pleasure, comfort, satisfaction, and joy).

To study traditional Doenjang characteristics, Doenjang was purchased from five different provinces: Chungcheong (CC), Gangwon (GW), Gyeonggi (GG), Gyeongsang (GS), and Jeolla (JL). To determine physicochemical characteristics, contents of reducing sugar, amino type nitrogen, salt, pH, and acidity were analyzed. The sensory characteristics were analyzed by sensory descriptive analysis. Reducing sugar content was highest for Doenjang from GW province. Amino type nitrogen content was highest for Doenjang from JL province. The salt content was highest in Doenjang from CC and GS provinces. After principal component analysis (PCA) based on sensory descriptive analysis, salty taste and aftertaste were highly correlated with overall acceptance. In the correlation analysis among chemical compounds and overall acceptance, Doenjang contained low reducing sugar content, and high pH value was positively correlated with overall acceptance. In conclusion, Doenjang with high pH value and salty taste and aftertaste have high overall acceptance.
The changes in taste components of kanjang made with barley bran during fermentation time were examined. The pH was gradually decreased and total nitrogen content reached to 0.7% at 90 days fermentation. Five kinds of free sugars, three kinds of volatile organic acid, and eight kinds of non-volatile organic acid were detected. Lactic acid known as abundant component in kanjang was not detected in kanjang made with barley bran. The content of free amino acid was $422.9{\sim}803.6\;mg%$. Glutamic acid was most abundant component among the amino acids, followed by proline and phenylalanine. Essential amino acid content was revealed $34.3{\sim}37.3%$. Based on result of sensory evaluation, it was most comfortable to eat sample of fermentation $45{\sim}60$ days.
This study is a result of the experiments to determine the optimum conditions of salting of Chinese cabbages for making tasty Kimchi. For the experiments, various methods of salting of Baechu were set up and the best method of salting had prepared Kimchi to investigated the best salt kind. In the two best results by method of salting salt kind, were investigated for salting time of Kimchi. There were certain amounts of Kimchi had prepared for each case of the combinations of the three conditions. Every case of Kimchi was refrigerated and was evaluated by sensory tests. In the salt concentration, pH and acidity of the Kimchi were measured. The results are as follows; In three cases of Kimchi, for salt concentration, level of 2.4-3.0$^{\circ}$ was maintained in Kimchi solid from the beginning to the end, while it was high in the beginning and gradually lowered in Kimchi liquid. The level of pH in both solid and liquid of Kimchi quickly dropped at the beginning of fermentation period and turned slow as time passed. And the level of acidity was increased little bit in the beginning, but it suddenly multipied until the third day of preservation. Since then, it had increased gradually thereafter as it was before. This experiments show that Kimchi can be the best taste in the case of Chinese cabbage soak in brine- free natural salt are kept for five hours.
