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 compared the results of Importance-Performance Analysis (IPA) on trail managerial conditions by trail section in Mudeung-Mountain Provincial Park. The study also examined the validity of using overall survey method (OSM: analyzing IPA from the data collected from all the trails without separating trails by section) by comparing the OSM results with those obtained from the survey by section. A total of 258 users who visited the Park was surveyed using questionnaire in the four designated trail sections during the September of 2000. The result of IPA showed that there are differences in twenty three attributes out of the 26 selected attributes (88.5%) among four trail sections. The overall IPA results obtained from the total of four trail sections were not the same with the IPA results from each trail section in twenty three attributes (88.5%) out of the 26 selected attributes. It suggests that we need to use a survey segmented by trail sections rather than a survey for overall trails to obtain better information for more efficient trail management.

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.

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.

From the day of luxurious inland river cruise ship started in Chongqing, China, the controversy is continuous; some people think those luxurious cruise ships on inland river might reduce the experience to enjoy the scenery of the Three Gorges, while some people think, which could improve the experience. In the study, the service facilities provided by luxurious inland river cruise ship will be evaluated by Pre-Post comparison based on IPA methods. After a review of the service facilities provided by luxurious inland river cruise ship running on Three Gorges areas. The tourists who would take the trip were asked to fill an questionnaire to examine the desired service facilities performance, which represents the highest level of the service facilities of the cruise ship that is expected by customers. After the trip, they were asked again to fill another questionnaire to examine the importance of service facilities and the performance of service. Pre-Post comparison would be examined to tell whether there is any change between pre and post experience. IPA would be used to evaluate the service facilities provided by inland river cruise ship. At last, some strategic suggestions to the development of inland river cruise ship are made.

A questionnaire survey was conducted with 213 users attending 12 dance academies in G Metropolitan City using the IPA statistical method. The following conclusions were drawn. The highest importance of a dance academy in IPA analysis was a professional teacher, followed by clean dance equipment, transit accessibility, dance academy fee, and a kind teacher. The highest satisfaction was a professional teacher, followed by various dance programs, teacher's choreography ability, a kind teacher, and transit accessibility. Based on the findings, dance academy users felt that the professionalism and kindness of teachers who directly teach them, academy fee, and equipment cleanliness associated with the age of COVID-19 were important. High satisfaction factors were teacher-related factors and transit accessibility. Therefore, it is considered that a professional and kind teacher and clean and hygienic environment will contribute to the activation of a dance academy.

High specific surface area zirconia with acid-basic property was synthesized by precipitation using reflux method or hydrothermal synthesis method using ammonium hydroxide solution as precipitant in the range of pH of Zr solution from 2 to 10. The prepared zirconia was characterized by the nitrogen adsorption, X-ray diffraction (XRD), isopropanol temperature programmed desorption (IPA-TPD), scanning electron microscopy and X-ray photoelectron spectroscopy, and the catalytic activity in the IPA decomposition reaction was correlated with the acid-basic properties. When using reflux method, high pH of Zr solution was required to obtain high fraction of tetragonal zirconia, and pure tetragonal zirconia was possible at pH 9 or higher. High pH was required to obtain high specific surface area zirconia, and the hydrous zirconia synthesized at pH 10 had high specific surface area zirconia of $260m^2g^{-1}$ even after calcination at $600^{\circ}C$. However, hydrothermal synthesis with high pressure under the same conditions resulted in very low specific surface area below $40m^2g^{-1}$ and monoclinic phase zirconia was synthesized. High pH of the solution was required to obtain high specific surface area tetragonal phase zirconia. In hydrothermal synthesis requiring high pressure, monoclinic zirconia was produced irrespective of the pH of the solution, and the specific surface area was relatively low. Zirconia with high specific surface area and tetragonal phase was predominantly acidic compared to basicity and only propylene, which was observed as selective dehydration reaction in IPA decomposition reaction, was produced.
