This individual case is the first study of Museum own by government but run by local people under the category of society institution-National Museum of Marine Biology and Aquarium (NMMBA). As NMMBA has mentioned ”Museum own by government but run by local people which using BOT operating method” as the base of the national museum operation which establish the trust between partners and their cooperate relationship. And more to the visitors' behaviors during the visit to museum's facilities, exhibitions, and services, we try to understand different types of visitors in terms of tour time, places, and different behaviors of visitors due to different factors of exhibitions' environment. In order to analyze NMMBA's visitors satisfaction and their attribute by discovering the attraction of that display topic during the visitors visiting exhibitions area. This research focuses on previous museum's visitors' research for discussion probe and its history. To understand if the visitors of NMMBA having different effect on the exhibitions, services, or factors on different environment and result in different visitors' behaviors after they are in the museum. However, it is hard by using the theory of quantitative or qualitative research to know the behavior of NMMBA's visitors. So this study focuses on the process of all the visitors' behavior during the visit in the NMMBA as the research content. Also by using observing and questionnaire methods as qualitative research, I hope this would be more complete for this study of visitor's behaviors.
