Shear strength parameters obtained from field tests are important factors in the analysis of slope stability. In this paper, sensitivity analysis was performed to evaluate the effect of input parameters on the analysis of slope stability. The input parameters selected for sensitivity analysis were slope angle, cohesion, and friction angle. Monte-Carlo Simulation method was to estimate input parameters for sensitivity analysis in slope stability, and the limit equilibrium method was used to calculate the factor of safety of slope stability. A rock slope, failed in the field, was used for the sensitivity analysis of input parameters in the analysis of slope stability. The result of analysis shows that the factor of safety of the rock slope was a little low. From partial correlation coefficient (PCC) of input parameters from the sensitivity analysis, slope stability was dependant mainly on cohesion and slope angle. The effect of friction angle was smaller than those of cohesion and slope angle on slope stability.

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.
