The purposes of this study were to investigate students' perception on importance and performance of service quality of university foodservice, and to examine Importance-Performance Analysis(IPA) of foodservice quality for male and female students. A total of 500 university students in Daejeon were surveyed and 432 responses were returned. Excluding responses with significant missing data, 412 responses were used for data analysis. In terms of importance of service quality attributes, 'sanitation(4.74)' category received the highest score, followed by 'food(4.36)', 'service(4.22)', 'convenience(4.01)', 'menu(3.90)' and 'atmosphere(3.73)'. In terms of performance, the highest service quality attribute was associated with 'convenience(3.30)', followed by 'service(3.06)', 'sanitation(2.95)', 'food(2.88)', 'atmosphere(2.79)' and 'menu(2.68)'. As the results of IPA, 'staff's kindness', 'overall quality of service', 'taste of the food', 'freshness of the food', 'overall quality of the food', and 'cleanliness of the facility' fell into the Quadrant IV(Focus here) for female students. On the other hand, male students' IPA grid illustrated that 'taste of the food', 'freshness of the food', 'nutrition of the food', 'sanitation of the food', and 'sanitation of the utensils' fell into Quadrant IV(Focus here).

This study aimed at investigating any differences perceived between the contractor and the contractee based on an importance-performance analysis (IPA) of foodservice quality attributes. Questionnaires were distributed to 200 personnel concerned in the Busan, Ulsan and Kyungnam areas and a total of 134 valid responses were used for analysis. Of the 23 foodservice quality attributes, the factors of 'food quality', 'employee service', 'hygiene and safety', 'customer orientation' and 'operation quality' were induced from a scale purification process through the exploratory factor analysis. The level of importance (p<0.01) of the 'hygiene and safety' factor and 'employee service' factor was not found to be significantly different between the groups. In the level of performance, the factors of 'food service', 'employee service', 'customer orientation' and 'operation quality' were found to be perceived significantly lower than expected by the contractor group. In the importance level, 'food quality', 'employee service', 'hygiene and safety', 'customer orientation' and 'operation quality' were rated by the contractor as 4.03, 4.30, 4.27, 4.01 and 4.12 points, respectively. In contrast, in the performance level, perceived 'food quality', 'employee service', 'hygiene and safety', 'customer orientation' and 'operation quality' were evaluated as 3.57, 3.94, 4.06, 3.83 and 3.95 points, respectively.

This study was intended to investigate differences in the recognition of the importance and performance of clinical nutrition management by using IPA. For the study, 100 clinical nutritionists working at medical institutions were analyzed. In all 17 categories of nutritional management, significant differences were observed in awareness of performance and importance. The categories with the greatest difference in importance and performance awareness were the nutritionist's participation in clinical nutrition education and related job development activities(1.38), and the lowest categories were the provision of therapeutic meals(0.69). Since IPA analysis results showed that participation in clinical nutrition education and related task development were both low in importance and performance, it should be improved first. A way to improve is for nutritionists to receive internal and external education. Above all things, for effective treatment, policies to include clinical nutritionist in the category of medical personnel, and cooperation between the medical sector and nutrition service management are necessary.

This study was conducted to provide basic data for prioritization of family support services by examining the importance and performance of family support for parents of children with special education. To achieve the purpose of the study, a questionnaire survey was conducted with 220 parents of children from special education nationwide. As a result of the study, the importance of all 29 family support service items was rated high, but the performance level was low, and statistically significant differences were found. In addition, as a result of analysis of importance and performance, family support services related to physical and physical well-being and disability-related support were evaluated as high-priority, low-practice services, and it was a task that should be presented as a priority in family support services. On the other hand, it was found that family support services in the areas of family interaction support or emotional well-being were considered to be services that should be avoided due to their low importance but high performance. Based on the results of these studies, the direction for the operation of family support services for children with special education needs to be suggested in the future.

In this paper, the importance of input factors of a DNN (Deep Neural Network) PM_2.5 forecasting model using LRP(Layer-wise Relevance Propagation) is analyzed, and forecasting performance is improved. Input factor importance analysis is performed by dividing the learning data into time and PM_2.5 concentration. As a result, in the low concentration patterns, the importance of weather factors such as temperature, atmospheric pressure, and solar radiation is high, and in the high concentration patterns, the importance of air quality factors such as PM_2.5, CO, and NO₂ is high. As a result of analysis by time, the importance of the measurement factors is high in the case of the forecast for the day, and the importance of the forecast factors increases in the forecast for tomorrow and the day after tomorrow. In addition, date, temperature, humidity, and atmospheric pressure all show high importance regardless of time and concentration. Based on the importance of these factors, the LRP_DNN prediction model is developed. As a result, the ACC(accuracy) and POD(probability of detection) are improved by up to 5%, and the FAR(false alarm rate) is improved by up to 9% compared to the previous DNN model.

Accurately evaluating and predicting the performance of facilities is a key task in establishing a maintenance strategy for facilities. The importance of performance evaluation is becoming more pronounced, especially when the aging of facilities requires a huge budget. In this study, performance assessment models were developed for road and railway tunnels. Delphi analysis was performed to identify sub-elements necessary to evaluate the performance of a tunnel. The relative importance of the evaluation factors was derived from the AHP analysis. The correlation analysis was performed between each assessment factor and the final result to verify the significance of the model. For the correlation analysis, the survey data measured through precision safety diagnosis in tunnels in use was applied. The cost effectiveness analysis was also conducted according to the scenarios with different composition of performance factors in order to improve the practical applicability of the evaluation model developed in this study.

In a large number of literature on of inspection tasks, one of the most consistent findings is the existence of large and consistent differences among inspectors. It is possible that the individual difference is described by the difference of cognitive skills, because cognitive skills are required more than manual skills in inspection tasks. Therefore, a set of cognitive factors in human information processing may underly human performance in inspection tasks. In this study, a cognitive skill was described as the relative importance of the cognitive factors involved. A hierarchical task analysis and a fuzzy hierarchical analysis were used to represent how the importance of cognitive factors contribute to inspection performance. An experiment was conducted using the computer simulations of PCB inspection tasks. The results revealed that the subject group with better performance showed the importance weights of cognitive factors in the following rank; (attention, perception, judgement, classification, recognition)<(detection)$\ll$(memory). The results of the experiment can serve as a selection criterion for efficient inspection performance and the information of skilled learning for an inspection training program. The usefullness of a hierarchical task analysis and a fuzzy hierarchical task analysis for the analysis of cognitive tasks are also confirmed.

This study was designed to examine the satisfaction of high school students with different types of foodservice management programs. The importance and the performance of foodservice management programs were evaluated based on the perceptions of high school students about food service characteristics affecting customer satisfactions. The average score of the attributes affecting the importance of school food service program was $4.27\pm0.49$ and the most important attribute was identified as 'the food safety $(4.68\pm0.67)$', followed by 'the taste of food $(4.66\pm0.65)$'. The average scores of all performance dimensions were lower than 3 point. 'Menu dimension' was rated as the lowest dimension $(2.61\pm0.89)$ and 'Food dimension $(2.79\pm0.70)$' was rated as the highest dimension. Significant differences among different types of foodservice management were perceived by respondents in the overall performance (F=40.244, p<0.001). Students who served by contract-conventional management rated significantly higher performance score on all of the performance attributes than the students served by other types of foodservice management. The results of the importance and the performance analysis present that student satisfaction is affected with the type of foodservice management programs and substantial differences lies between the perceptions of foodservice operations and students.
