Sampling inspection methods for quality control have been proposed a lot in the industry. However, the sampling inspection method for reliability, which is a quality over time, has been relatively less presented, and there are not many literatures that are clearly summarized. Therefore, this paper focuses on the reliability conformity test to verify that the reliability evaluation scale value of the target is satisfied during the reliability test. To this end, first, we look at the conditions that both consumers and producers can satisfy in terms of the OC curve and find out what sampling methods satisfy the desired level of producer risk and consumer risk. Next, two methods of the reliability sampling methods such as attribute and variable reliability sampling methods are examined. Specifically, the attribute reliability sampling method is a form of sampling plan where n samples are tested for a certain period of T hours and the lot is accepted if the number of failures is less than or equal to a certain number c. On the other hand, the variable reliability sampling method is a form of sampling plan where the lot is accepted if the reliability evaluation scale such as MTBF satisfies a certain standard. Both sampling plans may also use inspection tables.

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 focused on SNS use of Chinese students who are studying in Korea. Communication media like SNS is strongly related with socialization of foreigners. Thus, it is expected to verify relationship between current SNS use tendency of Chinese students and their settlement in Korea based on analysis on the factor influencing SNS use of Chines students. For the study on the factor influencing to SNS use of Chinese students in Korea TAM model was used as a research frame. Based on TAM theory technological attribute, individual attribute and social attribute were taken out as independent variables. Perceived ease of use and perceived usefulness are applied as mediator variables. In research conclusion, some hypotheses are adopted the same as existing theory, but some hypotheses for example service quality and individual attribute are rejected as variables which influence positively to mediator variable perceived easy of use. For the next research more various variables and nationwide sampling will be needed. Based on this research it is expected to be analysed correlation between foreigners settlement in Korea and communication media like SNS.

A group of Hanwoo (Korean cattle) steers (n=14,386) was sampled from a commercial abattoir located in Seoul over one year period (spring, summer, autumn and winter) and their carcass traits were collected. Carcass traits assessed by an official meat grader comprised degree of marbling, meat color, fat color, texture and maturity for quality grade, and back fat thickness, ribeye area and carcass weight for yield grade. A heavier carcass with a higher marbling score, more red meat color and white fat color received better quality grade (p<0.05). Regression analysis showed that the marbling score was the strongest attribute (partial $R^2=0.88$) for quality grade. Lighter carcasses with a thinner back fat and larger ribeye area received higher yield grade score. The back fat thickness was the most negative determinant of yield grade (Partial $R^2=-0.66$). The slaughter season had a little effect on quality and yield grades. As slaughter weight increased, back fat thickness and ribeye area increased linearly, whereas marbling score reached its asymptotic level at approximately 570 kg. As a consequence, quality grade showed a considerable improvement up to 570 kg, but increases in slaughter weight afterward showed a little benefit on quality grade. There was a clear curvilinear relationship between slaughter weight and yield grade in that the yield grade reached its highest point at approximately 490 kg and decreased afterward. These results suggested that 570kg at the age of 24 months might be the economic slaughter weight for quality grade but 490 kg for yield grade.

Logistics service is one of the most frequently addressed competitive edges exercised by container terminals that face fierce competition. Many of researches have tried to assess the logistics service quality and attempted to propose the strategic ways to manage it. However, it has been known that quality is a multi-dimensional construct and not all quality attributes are viewed as equally important to customers. Each quality attribute has different implications for customer satisfaction. Timko (1993) has developed customer satisfaction (CS) coefficient based on Kano model. The CS coefficient is indicative of how strongly a service quality may influence customer satisfaction. This study attempted to identify the satisfying/dissatisfying quality factors using Kano model and CS coefficient. In so doing, several satisfying and dissatisfying quality attributes in logistics service quality were identified.

A consumer survey was conducted for the subject of a total of 503 housewives in Korea, with the questionnaires on the quality attributes for Korean native chicken. The responding results collected were used for the importance-performance analysis of the quality attributes involved in production, processing, distribution, and consumption of Korean native chicken. The quality attributes with both relatively high importance and performance ("keep up the good work") were chicken origin, shelf life, freshness, and safety issues, while those with high importance but low performance ("concentrate here") were chicken breed certification and refrigerated/ frozen state. Respondents were also interested in lean meat and protein content of the chicken meat. In the aspect of eating quality attributes, chewiness was the most important one. The survey shows tenderer, chewier, and more flavorful chicken meat will be preferred and a new chicken breed with those eating quality attributes needs to be developed.

This study was designed to develop the strategy plans for the customer satisfaction on foodservice in the senior care facilities. For this, we examined the level of the customer satisfaction and foodservice quality. Additionally, the association between service quality, customer satisfaction, and social, psychological, physical factors of the aged were tested. Data from convenience samples from 3 senior care facilities were collected by using a questionnaire. Exploratory factor analyses were completed on 20 attributes for the food and service quality and 7 items for the social and psychological states of the aged, respectively. Cronbach's a was estimated for reliability, and Pearson correlation and multiple regression analysis were used for statistical analyses. The level of the satisfaction on foodservice was 4.01 of 5.0. The satisfaction on foodservice did not show the significant differences by gender, education level, BMI, and socio-psychological satisfaction. But the foodservice quality and the satisfaction showed significant difference by income and physical problem, and the goal of life of the eldely, respectively. Multiple regression analyses revealed that the determinants of the customer satisfaction on foodservice were the core quality of product, confidence, professionalism of employees and secondary quality of products. Especially, the kindness of employee is the most important attribute of the foodservice. Based on these results, we can set the strategy plans as follow: (1) the introduction of the foodservice evaluation system (2) the deployment of the event activities for offering fun to the customer (3) the continuous training of employees for ensuring the professional and kind service system, and (4) the introduction of selective menu system and take-out service of menu.

This study had the following four objectives: a) to measure the quality attributes of school foodservice based on responses of students, parents, and faculty members, b) to compare the quality attributes by city and province, c) to analyze the overall satisfaction of the respondents, and d) to identify the effects of the quality attributes on overall satisfaction by city and province. Questionnaires were distributed to 5,560 students, 1,920 parents, and 1,920 faculty members, and were collected using on/off-line mail (collection rate: 100%). The data were analyzed using SPSS for descriptive analysis, one-way ANOVA, and multiple linear regression analysis. From the quality attributes analysis, 'providing information on foodservice' was perceived as being performed well by the students (78.8), parents (76.0), and faculty (87.7). However, 'pleasant foodservice environment' was given low scores by the students (62.4), and 'entertains suggestions offered to foodservice' was perceived as low by 66.1% of the parents and 74.9% of the faculty. Upon comparing the quality attributes by city and province, the majority of scores by students and parents in Busan were significantly higher than those of students and parents in others geographical areas. The overall satisfaction levels (scores) were as follows: 66.4 for students, 70.0 for parents and, 76.8 for faculty. Finally, in the regression results, which showed the effects of the quality attributes on overall satisfaction by city and province, improvements of 'food taste', 'kindness offered by employees', and 'menu variety' would increase satisfaction in most cities and provinces. However, other identified attributes were significantly different among the 16 cities and provinces that were examined. Therefore, these regions will need to make different efforts to improve customer satisfaction for school foodservice.

This study had purpose to examine the consumers preference and buying property of processed products by rice, barley, wheat, bean. For the study, the interview was conducted of 300 samples more than 19 years of age. We attempt to examine consumers' preference and individual properties when purchasing processed grain products. Questionnaire was filled for the 23 variable by referring to previous studies to investigate the properties to consider when consumer purchasing the products. To conceptualize, reduce the high correlation parameters by factor analysis. The results attribute to seven factors that safety, brand/image, taste/shelf life, convenience seeking, preferred high-quality, price, consumption patterns. These properties showed significant differences in demographics. First, there was statistically difference by age in safety, brand/image, high quality preference, taste/shelf life. Second, Safety and high-quality preference were the difference between jobs, and depending on household income were significant difference in consumption patterns. We analyzed the purchasing preference by purchase frequency. Ramen, bread, beer are higher purchase frequency than any processed grain products. On the other hand, frozen rice, soybean paste, red pepper paste that are used primarily domestic raw, were lower purchase frequency. But the difference of purchase property according to products was very similar that the highest factor is price, the following factor as taste. Based on these findings, the implications and the limitations of the study were presented.

The purpose of this study was to identify the differences of older adults' perceptions of foodservice quality attributes of current offerings in Continuing Care Retirement Communities (CCRCs) in terms of their lifestyles (length of residency, special diet, housing option, travel frequency, dine out frequency), dining frequency, and demographics in the dining room of CCRCs. The survey was administered to residents in three CCRCs. Data was analyzed for 140 surveys using t-test, ANOVA, and factor analysis. This study found female older adults perceived the following attributes were more important than male ones: presentation of food, color and garnish, texture of vegetables, taste and flavor of food, and respectful attitude of serving staff. Older adults who have a special diet perceived the seasoning and bite sized pieces were more important than those who have a general diet. Also, there were significant differences between frequent visitors and occasional visitors in the dining room of CCRCs. By knowing the differences by residents' demographics and residential characteristics, the foodservice manager can establish strategies to increase the dining frequency of residents in the dining rooms of CCRCs.
