단체급식 및 대형 할인점에서 사용 및 판매되는 전처리 농산물중 급식에서 사용빈도가 높은 감자, 당근, 양배추에 대한 품질 평가를 실시하였다. 품질평가를 위해 관능 품질검사와 이화학적 분석이 이루어졌다. 전반적으로 대기업 급식업체에서 생산하는 전처리 농산물과 중소규모의 급식 납품업체에서 공급하는 제품 간의 큰 차이를 보이지 않았다. 또한 학교급식에 납품하는 업체의 전처리 농산물이 관능 품질검사에서 높은 점수를 나타내어 학교급식에서 사용되는 전처리 농산물의 품질이 높은 것으로 나타났다. 반면 대형할인점에서 판매하는 양배추, 당근, 감자의 품질은 개선의 여지가 보였다. 관능 품질 검사와 이화학적 분석 결과의 상관관계 분석에서는 "pH", "환원당"과 "산도"가 전처리된 양배추, 감자, 당근에서 관능 품질 검사 항목과 높은 상관관계를 나타냈고 이는 PLSR 분석을 통해서도 확인할 수 있었다. 향후 이들 농산물의 품질 검사에서 주요 분석항목으로 사용이 가능하리라 여겨진다. 전반적으로 단체급식에서 사용하는 전처리 농산물의 품질은 적정한 수준으로 여겨지나 가장 우려되는 부분이 식품의 안전성임을 고려할 때 다량 급식되는 식재료의 입고에서 조리-배식단계까지 주의가 확보되어야 할 것으로 여겨지고 실제 입고 후 조리 및 배식 전 과정에서의 분석이 향후 필요할 것으로 여겨진다.

The purpose of this study was to investigate the effects of a quality assesment of a university dormitory foodservice on the satisfaction degree, value awareness and relationship intention toward the foodservice. A total of 328 questionnaires were completed. Using SPSS package, Cronbach's alpha, analysis of variance and multiple regression analysis were applied. The results are as follows. First, the quality assessment of the foodservice varied depending on the period of service utilization. Customers of less than one year rated the nutrition supply of the university foodservice the highest, followed by those who were customers for more than 3 years and those who were customers for 2 to 3 years, respectively. Second, the quality assessment of the foodservice was substantially influenced by price as compared to service quality. Third, the quality assessment was significantly influenced by the price appropriateness of the foodservice. Fourth, foodservice assessment items such as customer-centeredness, pursuit of nutrition supply and food quality had a meaningful effect on the satisfaction degree toward the university foodservice. Fifth, customer-centeredness, pursuit of nutrition supply and food quality had a significant effect on relationship intention. Sixth, among the items of value awareness for the foodservice, value assessment as compared to service quality, and not price appropriateness, greatly affected the relationship intention. Seventh, the overall degree of satisfaction for the foodservice affected the relationship intention.

Purpose: This study examined how many determinant factors (service dimensions, food quality, and price perception) affect revisit intention. This practical concept is service quality (SERVQUAL), customer satisfaction, and repeated/revisit behavioral intention based on the theory of reasoned action (TRA). Research design, data and methodology: This research applied a hybrid mixed-method comprising exploratory and explanatory sequential design by Creswell (2014). The 400 responses were collected in four townships in Myanmar. This study drilled down to exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) prior to test the hypothesized factor structure of all the variables resulted in the form of the goodness of fit. For further data analysis, structural equation modeling (SEM) was applied to test the relationships among the variables of the proposed model. Results: The results showed that perceived service quality, food quality, and price perception have direct effects on customer satisfaction and indirect effect on revisit intention. The perceived service quality has the most significant influence while the food quality has the least influence on customer satisfaction. Conclusions: The results are useful for the restaurant managers to better understand the significant strategic choice factors to improve higher quality service amongst restaurants both domestic and international under the stiff competition.

Purpose: This study was conducted to find ways to improve foodservice quality and satisfaction of middle school students in school lunch service. Recognition of concerns about school lunch and quality attributes was evaluated by gender. And we tried to investigate quality attributes which could affect degree of foodservice satisfaction by gender. Methods: Two hundred students from each of 6 middle schools (3 schools in urban and 3 schools in rural) in Gyeonggi Province were surveyed using self-developed questionnaires. Total of 1,103 questionnaires (male 556 and female 547) were collected and data were analyzed using descriptive analysis, t-test, cross table and stepwise multiple regression by SPSS 11.0. Results: There were not significant differences in average importance scores (male 4.09, female 4.06) and average performance scores (male 3.36, female 3.30) of quality attributes between middle school boys and girls. But there were significant differences in 7 and 6 of 25 quality attributes in evaluating importance and performance respectively by gender. There was not a significant difference (male 3.13, female 3.24) in degree of foodservice satisfaction by gender. But there were significant differences in the distribution of satisfaction. Stepwise multiple regression analysis showed that degree of satisfaction was influenced by a taste of food, quick complaint handling, providing favorite foods, and food hygiene in male students (F=$51.1^{***}$, adjusted $R^2$=.265). Degree of satisfaction was influenced by a taste of food, providing favorite food, proper meal prices, providing a wide variety of food in female students (F=$91.4^{***}$, adjusted $R^2$=.399). Conclusion: We found out that there were significant differences in quality attributes when evaluating importance and performance and in quality attributes which could affect foodservice satisfaction by gender.

Market segmentation helps providers to find better marketing opportunities and allows foodservice managers to develop the right product for each target market. Therefore, this study, taking university faculty and staff as subject, is intended to diagnose the relative value of service quality attribute, on the basis service quality scenario of faculty foodservice; to suggest price for improving customer loyalty in market segments. A questionnaire was developed ar d mailed to 600 Yonsei university faculty and staffs. A total of 385 questionnaires were usable; resulting in a 58.7％ of faculty and a 69.7％ of staff response rate, respectively. Statistical data analysis was completed using the SAS/Win 6.12 for descriptive Analysis, ANOVA, principal factor analysis, cluster analysis, reliability test and discriminant analysis. The results of the study are as below. Eighteen questions were selected for measuring respondents' lifestyle by AIO method and the seven lifestyle factors derived from factor analysis and aggregated distinct 4 clusters. Service quality attributes of the scenario were determined with 'food quality', 'menu variety', 'atmosphere', 'fast service', and 'clean and sanitation'. 'Food quality', 'menu variety', 'atmosphere', 'fast service', and 'clean and sanitation', in decreasing order, were identified as improving customer loyalty. However, most faculty and staffs were satisfied with the present meal price. The result of this study indicates that the relative value of service quality was differed significantly among the various market segments. 'Food quality', 'menu variety', and 'atmosphere' were determined as major service quality attributes. Thus, customer loyalty could be increased by improving food taste and quality, atmosphere, and service delivery. (Korean J Community Nutrition 8(4) : 556 ∼565, 2003)

This study was performed to investigate the quality characteristics of noodles made from four different potato varieties: Atlantic, Go-un, Sae-bong, Jin-sun, and wheat flour. Quality characteristics of five noodles were analyzed by general components analysis, cooking quality (rate of water absorption, cooking loss, and volume increase), and mechanical textural properties. Some variations existed in wheat- or potato-based noodles for the general components analysis, but no clear trend was observed. Higher values in the rates of water absorption, cooking loss, and volume increase were observed for the wheat flour noodle, while some variations were observed for potato noodles depending on the variety. The wheat flour noodles exhibited higher values of textural characteristics obtained from the texture profile analysis, except for adhesiveness. Higher gluten contents as well as lower ash contents in the wheat flour noodles compared to the potato noodles are thought to be the two key factors contributing to this finding.

The purposes of the study were to examine food purchasing management practices and to assess dietitians' awareness on food quality standards, use of food purchasing guidelines(food quality guidelines, supplier selection criteria), and organizational collaboration related to purchasing at school food service. A total of 400 dietitians working at elementary schools in Kyunggi Province were surveyed and 247 responses were returned. Excluding responses with significant missing data, 240 responses(60%) were used for data analysis. Compared to the previous reports, competitive bidding and shorter contract periods were preferred for purchasing food supplies. A dietitian, school staff, and food service staff participated in receiving and inspection together at 58.4% of the schools. An average score of the dietitians' awareness on the food quality standards was 3.28 based on a 5-point scale(1:strongly disagree, 5:strongly agree). Their awareness scores for the quality standards related to the genetically modified organism foods, organic foods, and pesticide residues were the lowest. The awareness scores increased significantly with their age(p<.001). In general, the food purchasing guidelines were used well at the schools ; the usage levels of the food quality guidelines and supplier selection criteria were significantly different by length of operation(p<.05) and dietitians' age(p<.05), respectively. The dietitians' perception score of the organizational collaboration related to purchasing was rated 3.46 and differed significantly by dietitians' educational background(p<.05). For improving food procurement management, standardized food quality and purchasing criteria need to be developed. As the demands on high quality food supplies increase for school food service, the dietitians should improve their knowledges on the food quality standards and implement effective and creative purchasing methods.
