The purpose of this research is to assess potential area of mountainous wetland by GIS and AHP (Analytic Hierarchy Process). Mountainous wetland is topographically located at high altitude, so it's difficult to approach for researchers. And, it's difficult to investigate systematically because of the insufficient information of mountainous wetland. Therefore, it's necessary to study on potential area of mountainous wetland for systematic and efficient investigation. This research selected slope, wetting index, land-cover map and soil map as assessment items indicating environmental characteristics of mountainous wetland and established them by GIS DB. And, spatial value of mountainous wetland for each assessment item was drawn by existing investigation data and overlap analysis of mountainous wetland. Based on the numerical results of each assessment item, a survey was conducted and relative importance for each assessment item was decided by AHP. As the result, slope was the highest as 0.550 and ground coverage was the lowest as 0.083. The subject of this research was Yangsan-si and Ulsan of Gyeongnam and an analysis was conducted for mountainous wetland in those research areas. As the result, all of wetland was distributed in the range of potential area. And, field survey and literature search were conducted for the point that the distribution of mountainous wetland is expected. As the result, mountainous wetland was distributed. Therefore, mountainous wetland should be excavated through the results of this research and it should be helpful for effective investigation as providing information necessary to the following studies on mountainous wetland.

Objectives: There should be an objective analysis on the academic competency for incorporating Computer-based Test (CBT) in the education of traditional Korean medicine (TKM). However, the Item Response Theory (IRT) for analyzing latent competency has not been introduced for its difficulty in calculation, interpretation and utilization. Methods: The current study analyzed responses of 390 students of 8 years to the herbology test with 14 items by utilizing Rasch model, and the characteristics of test and items were evaluated by using characteristic curve, information curve, difficulty, academic competency, and test score. The academic competency of the students across gender and years were presented with scale characteristic curve, Kernel density map, and Wright map, and examined based on T-test and ANOVA. Results: The estimated item, test, and ability parameters based on Rasch model provided reliable information on academic competency, and organized insights on students, test and items not available with test score calculated by the summation of item scores. The test showed acceptable validity for analyzing academic competency, but some of items revealed difficulty parameters to be modified with Wright map. The gender difference was not distinctive, however the differences between test years were obvious with Kernel density map. Conclusion: The current study analyzed the responses in the herbology test for measuring academic competency in the education of TKM using Rasch model, and structured analysis for competency-based Teaching in the e-learning era was suggested. It would provide the foundation for the learning analytics essential for self-directed learning and competency adaptive learning in TKM.
