This study analyzed the Importance-Performance Analysis of selective attributes of Ethnic Food Restaurant. A total of 369 questionnaires were analyzed. Five factors were obtained from factor analysis of Importance variance of selective attributes of Ethnic food restaurant: Factor 1 "Quality", Factor 2 "Service", Factor 3 "Physical environment", Factor 4 "Uniqueness", Factor 5 "Health". Also, "Quality", "Physical environment", "Uniqueness" factors influenced overall satisfaction. In addition, according to the IPA results, selective attributes with low satisfaction and high importance in the second quadrant were 'Sanitation that comfort hospitality', 'Level of service' and 'Price'. These results suggest that when customers select Ethnic food restaurant, they consider 'food price' and 'food quality'. Therefore, manager of ethnic food restaurant should take these improvement factors into consideration in order to meet consumer's expectations.

The purpose of this study is to understand the importance-satisfaction level for the improvement of the young farmers fostering support policy. According to the analysis result, the respondents answered that the current policy to foster young farmers is important. However, the actual satisfaction level of the project was found to be lower than the importance level. In the 'Keep up the Good Work' area, which is the first quadrant, 'a project to support young succession farmers and settling in farming' and 'a project to select and support succeeding agricultural managers'. It was found that the respondents highly evaluated the importance and satisfaction of the 'Young Succession Farmers Selection and Farm Settlement Support Project' and the 'Succession Farmers Selection and Support Project'. Therefore, it is necessary to gradually expand the project in the future.

The purpose of this study is to investigate and analysis importance for evaluation indicators in youth centers. The sample of it is 138 youth centers. Method of this analysis of importance for its indicators is AHP(Analytic Hierarchy Process). Evaluation domains in youth center are process evaluation, product evaluation, input evaluation and specialized program in order of importance. Also, it is important to evaluate in needs assessment, recruitment of youth instructor, participation of youth in decision making, connective project with schools, sanitation level of youth center, satisfaction research, efforts of improvement of youth center staff in evaluation indicators. The result of this study is that importance for evaluation indicators suggests developmental directivity in youth center management.

Purpose: This study conducted an empirical study to identify the current status of real estate managers' ESG awareness and to derive recommendations for improvement. Research design, data and methodology: A survey was conducted among those who actually manage real estate assets regardless of region. Descriptive statistical analysis, paired sample t-test, and IPA analysis were conducted using SPSS 27.0 statistical package. Results: The results of the t-test showed that respondents perceived their on-site management achievements to be lower than their perceived importance in all areas of ESG. In the IPA matrix, the mean of achievement is higher than 3, which is moderate. Environment (E) was found to be relatively low in importance. In the Social (S) aspect, the achievement level was low compared to its importance, and Governance (G) was found to be low in importance. Conclusions: Based on the analysis, it seems that policies are needed to emphasize the importance of environmental issues such as greenhouse gas reduction in the environment (E) sector and to strengthen realistic achievement in the social (S) and governance (G) sectors.

The tail probability of a function of a multivariate random variable is not easy to estimate by the crude Monte Carlo simulation. When the occurrence of the function value over a threshold is rare, the accurate estimation of the corresponding probability requires a huge number of samples. When the explicit form of the cumulative distribution function of each component of the variable is known, the inverse transform likelihood ratio method is directly applicable scheme to estimate the tail probability efficiently. The method is a type of the importance sampling and its efficiency depends on the selection of the importance sampling distribution. When the cumulative distribution of the multivariate random variable is represented by a copula and its marginal distributions, we develop an iterative algorithm to find the optimal importance sampling distribution, and show the convergence of the algorithm. The performance of the proposed scheme is compared with the crude Monte Carlo simulation numerically.

This paper aims to examine the farmers' perceptions of the importance and feasibility of climate change awareness and adaptive measures in agriculture, utilizing paired sample t-tests and Importance-Performance Analysis (IPA). Significant differences were found in farmers' views on the importance and urgency of climate change issues, with specific factors standing out. The IPA analysis identified key issues requiring sustained attention, including climate change magnitude, extreme weather events, livestock damage scale, pest fluctuations, and variability in flowering periods. Additionally, the study revealed significant disparities in farmers' perceptions of the importance and feasibility of adaptive measures, except for specific items related to heat indices.

The Kano model, a two-dimensional quality theory, is widely used as a useful tool for measuring potential customer requirements by utilizing the concept of the Potential Customer Satisfaction Coefficient (PCSC). There is growing evidence that the PCSC, comprising the Potential Satisfaction Coefficient (PSC) and Potential Dissatisfaction Coefficient (PDC) and utilizing Kano's four quality dimensions (A, O, M, and I), can be particularly useful in determining the relative importance of quality characteristics in IPA. Despite prior studies utilizing the PCSC concept for characterizing importance, attempts to determine the relative significance among quality dimensions have been relatively scarce. This study aims to use PCSC and IPA to demonstrate which quality dimension is more significant than the others. The author analysed 32 Kano related articles, encompassing 34 cases, using IPA. The results indicate that the proposed equations are valid for assessing characteristic importance, with O or M is perceived as more important than A or I.

The purpose of the study was to evaluate the perception of importance about prerequisite program(PRP) of dietitians. A questionnaire was developed to achieve research objectives and sent to random samples of 450 dietitians by a mail from July to August in 2000 ; 242(54%) responses were analyzed. The respondents used three-point-scale to rate their perception of importance about PRP from 1-"will be necessary" to 3-"very important". All statistical analyses were conducted using SAS package(version 8.12) in order to have means, standard deviations, One-way analysis of variance, Duncan’s multiple range test and t-test. The study results were summarized as follows. The rates of perception of importance about PRP were significantly different from 21 of the 37 contents among business and industry, health care and school foodservice and were significantly different from 16 of the 37 contents among direct and contract management(p<.05 or p<.01 or p<.001). Dietitians in business and industry had lowest perception of importance about PRP of other respondents. Generally, the item related to ‘‘employee hygiene practice’ had the highest perception level score among PRP in foodservice facilities. Results indicate that there is a need for increased education of dietitians about PRP and appropriate practices.

The classification of risk factors and the identification of risk acceptance criteria are core works to assess risk levels with high enough confidential level in the field of marine traffic environment. In the previous study work, the twenty kinds of risk factors and its assessment criteria for the domestic marine traffic environment were proposed. In this paper, with these previous studying results, the relative importance of the risk factors were analyzed by questionnaire survey of marine traffic experts using the analytic hierarchy process. The analysis results showed that the relative importance of the visibility restriction is the highest among the twenty kinds of risk factors, and the relative importance of the traffic condition is the highest among the five kinds of risk categories. As results from analysis, it is expected that the approaching method on the relative importance is to be one of basic techniques for the development of risk assessment models in the domestic marine traffic environment.
