Compared to the traditional format, the revised IPA is an effective method for selecting a management strategy as compared to the traditional IPA. Comparison between the traditional IPA and revised IPA with a management strategy has been, however, limited. Therefore, the difference between the traditional IPA and revised IPA was compared to select an effective management strategy in the Suncheon Bay Wetland Reserve. First of all, related papers were reviewed to select an appropriate revised IPA. It was found that Deng (2007)'s revised IPA was appropriate for quantifying service quality and a management strategy that affects the measurable satisfaction of visitors in the space. Second, the results of the traditional IPA were compared with the revised IPA in the Suncheon Bay Wetland Reserve and the management strategy of the revised IPA and the changes of management factors were discussed. It was found that some management factors deviated from the order of the quadrant "low priority for managers", "Concentrate management here", "Keep up the good work" were moved to the order of the quadrants "Concentrate management here", "low priority for managers" and "Possible overkill" in the revised IPA grid. The complexity as a management factor resulted in higher demand management than the traditional IPA, which moved from "low priority for managers" to "Concentrate management here". Management factors resulted in lower demand management than the traditional IPA moved from "Concentrate management here" to "low priority for managers"; these consisted of shade trees, exhibition exteriors, programs, and a guided tour. Also, management factors moved from "Keep up the good work" to "Possible overkill" consisted of relaxation facilities, glow of the setting sun, a hedge, and an exhibition interior. Over all, the revised IPA responded properly to changes in the measurable satisfaction of visitors to the Suncheon Bay Wetland Reserve. Therefore, a revised IPA should be provided for accurate and reliable guidelines when decision makers establish management strategies.

As a simple and practicable method, an Importance-Performance Analysis(IPA) is often used as a tool to study the satisfaction of tourists in Tourism. The IPA has two dimensions to attribute importance and performance(or satisfaction as in satisfaction research), and generally uses an interviewee self-reported approach to acquire performance and importance data. Many scholars have pointed out that the traditional IPA cannot meet the premise of its establishment. Therefore, several revised IPA have been proposed. Among them, Deng's IPA is the most representative. There are not many contrastive analyses between the traditional IPA and revised IPA in academia. The lack of comparative study will make it difficult to judge the difference and effectiveness of different IPA techniques. Taking Gyeongju Yangdong Village as an example, this study investigated and researched the degree of satisfaction of Chinese tourists using the traditional IPA method and Deng's modified IPA method respectively, and then analysed the differences between the two methods and their causes. Based on the analysis results, the study put forward suggestions for the improvement of tourism management in Gyeongju Yangdong Village.

This study focuses on hotel kiosks that have begun to be introduced in earnest in mid-priced hotels, and the quality attributes of hotel kiosks, which are expected to be introduced throughout the hotel industry in the future, and validates them using a revised IPA(Importance-Performance Analysis). An online survey was conducted targeting hotel users who had used hotel kiosk devices, and difference analysis and IPA analysis were conducted on 239 people, excluding 61 who responded insincerely. As a result of the verification, there was no significant difference in hotel kiosk quality attributes by age, but there was no significant difference by age. It was found that there was a significant difference. As a result of analyzing the difference between importance and satisfaction, it was found that there was a partially significant difference. These results suggest standards for quality attributes in hotel kiosks and provide academic implications for future research and practical implications for hotel management practitioners.

Daycare center is an important space for children's mental, physical and social development. Each space of daycare center should be designed and constructed considering interests of end-users such as children and teachers. However, insufficient related guidelines and standardized design and construction of daycare center to moderate potential risks of each space. This arises from the difference in perception of each space between end-users (head and sub teachers) and construction experts (designers and contractors). Therefore, research framework was developed for analyzing the factors of perception differences of each space in daycare center between these groups applied traditional and modified Importance-Performance Analysis (IPA). By comparing risk perception between end-users and experts in two methods, it can be support as construction guide for daycare center in the future and will help minimize conflicts in construction among stakeholders. Moreover, it was found that traditional IPA is comfortable to catch prior project perception of participants, and revised IPA is considered to judge outputs by identifying participant's importance based on the satisfaction of the project performance. Therefore, if IPAs are applied according to the characteristics of the circumstances, it is possible to analyze the perception difference between end-users and construction experts based on the context before and after the construction of the daycare center.

This study is a study on the service quality attributes of serving robots, which have recently been introduced in the restaurant industry, and was verified using revised IPA analysis. An online survey was conducted on consumers who used serving robot services, and 300 respondents were analyzed by difference analysis and IPA analysis, excluding 13 who responded insincerely. The verification results showed that there was no significant difference in the service quality attributes of serving robots by age, but there was a significant difference by age. Those in their 50s and 60s showed higher interest than those in their 20s and 30s. The difference analysis results of importance and satisfaction showed that there was a partial significant difference. The results of revised IPA analysis showed that interest in serving robots was high, but the service was not yet satisfactory. These results suggest the current level of consumer awareness of the service quality attributes of serving robots and provide academic implications for follow-up research and practical implications for a restaurant management expert.

The total amount of overseas plant orders obtained by Korean construction companies in 2015 decreased by approximately 51% from the previous year. While a chemical plant sector has the highest portion of the plant orders by accounting for 63% of the plant industry, its orders also decreased by approximately 43% in the same year. Recently, plant construction companies in overseas projects have been dominating the engineering sector owing to their advanced technology, experience, and accumulated knowledge. Therefore, measures must be taken to secure the competitiveness of domestic companies in the global plant industry. Especially, productivity management is an important issue to strengthen the national competitiveness with the development of construction technology. As the productivity influences long term growth, we analyze productivity obstacle factors by using the revised IPA, a technique to measure attribute importance and performance. With the identified factors, we suggest improvement plans and measures to enhance productivity of overseas chemical plant projects. This study will help the companies to come up with medium and long term measures by discussing results and implications it provides.

As the lifestyle of people today is evolving, the desire for convenient but nutritious food to replace home-cooked meals is increasing. As the market for Home Meal Replacement (HMR) has already reached 17 hundred billion Won, many studies on HMR selection attributes have been conducted, using traditional Importance-Performance Analysis (IPA). However, it was found that traditional IPA had some limitations. Therefore, the study used both traditional and the Revised IPA to examine the selection attributes of HMR sold at large discount store to compare outcomes. The results of the study show that by using the Revised IPA, many attributes differed from those found by the traditional IPA. Consequently, the study revealed aspects that have both linear and nonlinear relationships with customer satisfaction. Implications of this study could provide the foundation of business strategies for HMR manufacturers.

Purpose The purpose of this study is to examine the review of previous studies based on audiobooks, 1) using the IPA method, we examine the quality of audiobooks that listeners perceive as important and the quality of preferred audiobooks, 2) improvement directions for activating audio content and audiobook platform, to seek ways to establish strategic plans for the audiobook market. Design/methodology/approach This study conducted and experiment using three factors(usability, information and interaction) used in web service quality(WebQual). Usability consists of the availability of time, such as the use of audiobooks for hobbies and the ease of search. Information consists of the trends of the times, topics of converation and the latest trends. Interaction consists of the proportion and depth of celebrities. After that, grid analysis was performed using the traditional IPA method and the revised IPA method. It was judged that identifying and analyzing the preference for service provision and new content was more valuable than the Performance used in the existing method. Findings According to the results of the empirical analysis, it was found that the conversation material corresponding to informativity did not affect the audiobook during the online quality analysis. It is believed that improvements can be found through content production related to entertainment, webtoons, and general common sense that can increase listeners' interest. In addition, it was found that the advertising effect of celebrities corresponding to interactivity did not affect the results of this study, which should increase the concentration and immersion of listeners by increasing the technology for audiobooks.
