The purposed of the study was to assess customer satisfaction concerning foodservice quality characteristics by using developed DINESERV model for university employee foodservices. Specially, it was intended to develop the tool which assesses the differences between customer importance and perceptions of customer with actual foodservice delivery by university employee foodservices. Questionnaires were distributed to 300 un9iversity employees. Total 230 university employees responded with a usable response rate of 67.7%. Statistical data analysis was completed using SAS programs for descriptive analysis and t-test. The results of the study are as follows: 1) Employees´first choice was distance when they select foodserveices. They answered their preference as the first factor when they order menu in the foodservices. The first complain factor concerning university foodservices was the taste of food. 2) Customers did not satisfied with the foodservice quality of university employee foodservices. Importance mean score of service quality was 3.81 out of 5 but percption mean score of service quality was 3.10. Importance mean score of food quality was 4.11 out of 5 but perception mean score of food quality was 2.96. 3) Customers´satisfaction of service quality by dimensions were as following order: assurance > reliability > responsiveness > empathy > tangibles. And customers´satisfaction of food quality by dimensions were as following order: nutrition > food > price > sanitation. There were no significant difference about customer satisfaction between contracted management and self-operated.
The study was curried out to collect information to establish a framework for nutrition education for the prevention of chronic degenerative disease. We analyzed differences in diet quality, food habits and health status of workers by work condition. Anthrometric parameters of height, weight and body fat were measured and biochemical parameters including glucose, total cholesterol, GOT, GPT and hemoglobin were determinded for 194 subjects. To assess the nutrient intake and diet quality of workers, dietary intake was measured by the day 24-hour recall method, Average daily nutrient intake, except for phos-phorous and vitamin C was lower than Korean RDA. The obesity related behavior score was significantly better in laborers than in office workers, while chronic degenerative diseases related to food habit score was significantly better in laborers than in office workers, while chronic degenerative diseases related to the food habit score was beet in offices workers than in laborers. Blood pressure, blood glucose levels were significantly higher in laborer than in office workers. Dietary variety score (DVS) food composition group score(FCGS), mean adequacy ratio(MAR) of office worker were better than those of labor workers. When diet quality was evaluated by FCGS(food composition group score) 16.0% of the subjects acquired 5 points and 14.4% of the subjects acquired 2 points. MAR and INQ showed a significantly positive correlation with DVS and FCGS . This results indicated that the onset possibility of hypertension and diabetes mellitus among chronic degenerative disease was higher in laborers than in office workers, while the onset possibility of obesity was higher in office workers than in laborers. In conclusion the overall diet quality of office workers is betters than that of laborers, therefore, nutrition education for prevention of chronic degenerative disease of industrial workers needs to be more focused on the improvement of the health status of laborers.
Sister chromatid exchanges(SCE) in peripheral lymphocytes is recently used as a biomarker for increased cytogenetic damage in smokers. The purpose of the investigation was to determine if there were any relationships between dietary factors and their DNA damage as measured by SCE test in a group of 62 male cigarette smokers and 36 non-smokers. As expected, smokers as compared with non-smokers had high SCE levels (10.59$\pm$0.21 versus 9.23$\pm$0.17 SCE/lymphocytes ; p<0.05). No significant relationships were observed between SCEs and age in smokers and non-smokers. In smokers, SCEs were negatively correlated with egg frequency score(r=-0.336) and total food frequency scores(r=-0.283). In non-smokers, SCEs were positively correlated with white vegetable frequency score(r=0.333) and instant food frequency score(r=0.382). There was a positive association between SCEs and the history of coffee intake of smokers(r=0.318). SCE frequency was not influenced by any other dietary factors considered ; dietary diversity and quality scores, alcohol consumption, use of processed foods and intake of burned food. No significant relationships were found between SCEs and serum cholesterol or other hematological parameters of the subjects. These results indicate that increased egg frequency score, total food frequency score which reflects dietary quality, and decreased coffee intake may reduce cancer risk by preventing smoking-induced DNA damage as reflected by sister chromatid exchanges in human lymphocytes.
To assess the food intake and diet quality of preschool children in Pusan, dietary survey was conducted with 176 subjects using 24hr recall method. Diet quality was assessed by food group pattern, dietary diversity score(DDS), dietary variety score(DVS), and dietary frequency score(DFS). The total number of food items consumed was 307. The foods consumed most frequently were rice, Korean cabbage kimchi, milk and green onion. When investigating the consumption pattern of major six food groups, 38.1% of subjects consumed all six groups. Food group was missed in order of fruit(41.5%), sweet(19.9%), dairy(16.5), vegetable(4.5%) and meat(1.7%). The mean values of DDS, DVS, and DFS were 5.16, 13.82, and 16.07 re spectively. Persons who had higher DDSs also had higher DVSs(p<0.001). DDS, DVS and DFS correlated positively with NAR(nutrient adequacy ratio) and MAR(mean adequacy ratio) significantly. Associations between the NAR of most nutrients and MAR with DVS and DFS were higher than those between the NAR of most nutrients and MAR with DDS. People with DDS of above 6 or DVS of above 16 or DFS of above 21 met two thirds of recommended dietary allowance for nutrients. Based on the result of the food group intake, the food intake of subjects was not adequate, especially the fruit and dairy groups. When assessing the dietary quality of subjects using DDS, DVS and DFS, many people appeared not to have a desirable food intake.
Fruits are good sources of vitamins, minerals, fiber, and phytochemicals, which are known to reduce serum lipids, oxidative damage, and blood pressure as well as improve blood glucose control. The purpose of this study was to estimate nutrient quality indices of fruits by carrying out a critical analysis of pre-existing methods according to their nutritional compositions. Four methods were used to assess the nutrient indices of 26 fruits, which are frequently consumed by Koreans based on the fourth Korean National Health and Nutrition Examination Survey (2009). Naturally nutrient rich score (NNR), nutrient rich food (NRF), nutrient adequacy score (NAS), and nutrient density score (NDS) were used to calculate nutrient quality indices. The Korean Nutrition Society Food Composition database of fruits based on 100 g edible portions was used. The algorithm of each method included the mean percentage of daily values (Dietary Reference Intakes for Koreans, 2010) for particular nutrients based on consumption of 1,900 kcal/day. The relative score indicated that strawberries, kumquat, and lemon had high nutrient quality indices. In addition, mango, lemon, persimmon, strawberry, apricot, and tangerine fruits are rich in antioxidant nutrients such as ${\beta}$-carotene, vitamin C, vitamin E, and selenium. However, scores of nutrient quality indices did not imply that higher scores of particular fruits are superior. We suggest moderate seasonable consumption a variety of fruits. Our results can be used as a reference for consumers when they choose fruits.
The purposes of this study were to identify the students’ perception and to evaluate the satisfaction with the quality of school foodservice in Chungbuk Province. A questionnaire survey of 900 students was conducted and 370 completed questionnaires were available for the purpose of the statistical evaluation. Statistical analyses were performed on the data utilizing the SAS V8.2 program. Importance, performance and satisfaction scale were composed of 5-Likert scales. The main results of this study were summarized as follows: The degree of importance and performance on twenty three attributes and the degree of satisfaction with four dimensions and overall satisfaction were measured according to type of school, location of school, place for eating, type of foodservice system and type of foodservice operation. The importance score was significantly higher than the performance score at all quality attributes except for the food appearance. The performance score of ‘waiting time’ and ‘atmosphere’ was less than 3 point out of 5 scale. The average satisfaction score for the quality dimensions of food, sanitation and service was 3.35, 3.19 and 3.10 point out of 5 scale, respectively. The satisfaction score for dimension of environment was 2.93 point out of 5 scale. The score for overall satisfaction was 3.27 point out of 5 scale. The satisfaction score for elementary school foodservice management was significantly higher than middle and high school foodservices. The satisfaction score for commissary foodservice operations was significantly higher than conventional foodservice operations. Using survey results as a base, the dieticians of school foodservice are required to meet the needs of the students and increase students’ satisfaction.
This study was undertaken to investigate the effect of Opuntia humifusa on the improvement of quality properties of Korean Jeolpyun. Chemical and mechanical properties of unsupplemented Jeolpyun and Jeolpyun supplemented with 1%-4% O. humifusa. Also, a sensory evaluation by a trained panel was conducted. Concerning color difference, the L value decreased, but a and b values increased as O. humifusa content increased. Texture analysis revealed that hardness, cohesiveness and adhesiveness were the highest in the unsupplemented control group. The texture parameters decreased as the O. humifusa addition ratio increased. In sensory evaluation, color and taste scores were highest score in 2% O. humifusa supplemented samples, with no difference in flavor being evident. Chewiness and adhesiveness scores were highest score in 4%-supplemented O. humifusa samples. Overall quality score was highest in the 2% O. humifusa samples. The addition of $2{\sim}3%$ O. humifusa optimizes Korean Jeolpyun.
This study was performed to assess diet quality in the postmenopausal women. The data of dietary intakes were obtained using food frequency questionnaires which were collected from 151 postmenopausal women in urban area. We evaluated nutrient intake and diet quality. Diet quality was assessed by NAR(nutrient adequacy ratio), FGIP(food group intake pattern), DDS(dietary diversity score), DVS(dietary variety score), FGS(food group score), DQI(diet quality index). Nutrient intakes of the subjects were close to Korean RDA. Nutrient composition of the diet(in percentage of total energy) was 64% carbohydrate, 15% protein, and 19% protein, and 19% total fat, that was close to 65 : 15 : 20. NAR of most nutrients, except vitamin A, E, were higher than 0.75 and MAR was 0.88. NAR and MAR of the subjects in theis study were higher than those of the subjects of rural area in other studies. The subjects who consumed the five food groups were 60.9%. The mean of DDS was 4.5. The subjects who consumed more than 61 dish items during a month were 61.5%. The mean of DVS was 62.4 and it was significantly higher in the elder age group. 67.6% of the subjects were below FGS of 12. The mean of FGS was 10.6 and few subjects consumed serving numbers of each food groups which were recommended for Koreans. 55.0% of the subjects were DQI scores of 0, 1, and 2. The mean of DQI was 2.3 and few subjects followed the five dietary guidelines for Korean.
This study used questionnaires to investigate the safety awareness for imported foods by 365 male and female adults in Taejon. The results of the study were as follow : By factor analysis, the subjects' behaviors and awareness of the imported food was grouped into 3 factors such as 'health and quality factor', 'purchasing factor' and 'contamination factor'. 'Health and quality factor' and 'purchasing factor' were not recognized negatively by the subjects, moreover' contamination factor' was recognized very highly. The subjects' concern and worry about the imported food was also very high. The marital status, education level, nutriton knowledge adn recognition level of contamination by pesticides and heavy metals of foods partially affected the recognitio level of imported foods. The major selection criteria of imported food were distribution period(36.3%), price(28.8%) and purchasing experience(17.3%). The imported food mean discrimination score was 8.4±3.1 out of 13. The worst discriminatio score was red pepper. The subjects' experiences with imported foods selection affected the most instead of education level or nutrition knowledge. The higher discrimination score group more negatively recognized imported food and contamination recognition level was higher whereas the lowerdiscrimination score group more positively recognized the purchasing frequency and with to buy more easily. But both groups desired to reinforce contamination control. The better discrimination score of imported food pooring recognized sanitation concerns(p<0.05), quality(p<0.05), cooking convenience(p<0.01), desire for more variety(p<0.05), and the higher contamination recognition level(p<0.05) and desire to reinforce contamination control(p<0.01).
It is suggested that evaluation of diet quality may be a great indicator of nutritional assessment. The aim of this study was to evaluate the diet quality of children and adolescents based on nutrient and food group intake and Diet Quality Index-International (DQI-I). This survey was conducted through questionnaires and diet record survey to 477 students (elementary school students; n = 131, middle school students; n = 136, and high school students; n = 210). The results showed that high school students were significantly more often to skip breakfast compared with the other groups. The middle and high school students consumed significantly higher intakes of food and energy compared to the elementary school students. Also the number of nutrients in Index of Nutritional Quality (INQ) < 1.0 of high school students were significantly higher than that of elementary and middle school students. The Korean's dietary diversity score (KDDS) of elementary school, middle school and high school students were 4.1, 4.4 and 4.3 respectively. The average DQI-I of elementary school, middle school and high school students were 66.7, 65.5, and 63.7, respectively and there was significant difference. Also, middle school students showed to have higher score in variety and adequacy category compared with the other groups, and elementary school students appeared to have higher score in moderation category. In conclusion, high school students appeared to have unhealthy dietary habits in terms of high frequency of skipping breakfast and lower INQ and DQI-I score compared to the elementary school and middle school students. Therefore, the proper dietary management should be needed for high school students.
