This work is a collection of academic studies on different kinds of culture in the Moon River Basin, which were case studies of the Khmer, Lao and Kui ethnic cultures as well as the local history in Surin Province. The collection comprised five research reports, two scholarly articles, and one survey report. The river basin was an important agricultural area in the southern Isan region. It was also a cultural, historical, architectural and archeological area spanning from the Funan to ancient Khmer civilizations, which were considered some of the most important civilizations in the world (p. 34). The survey on culture in the Moon River Basin, their structures and perceptions revealed that the pre-test scores on the perceptions on the culture in the river basin of grade 6, grade 9, grade 12, and undergraduate students in the province were at a low level (pp. 113-116). The results of an ethnological study on the cultures and histories in the river basin which focused on cultural assimilation of the Kui, Khmer and Lao ethnic groups revealed that Kui communities had strongly maintained their ethnic identity and traditions (pp. 119-125). The population in the southern Isan region, formerly called the forested Khmer township, consisted of residents speaking Khmer, Kui and Isan Thai, although Isan Thai originated from this region. However, during the Thonburi Period, townships were clustered together based on similar cultures until there was cultural assimilation under the concept of the nation state (p. 124). Additionally, the study on the elephant raising culture of the Kui in Surin province  focused on the issue that elephant raising was not only obliged to change economically but were also concerned with ethnic beliefs (pp. 125-156). In the cultural analysis on belief system of the Kui, it was found that, although certain held beliefs were based on Buddhism, a belief in supernatural powers still prevailed and played a significant role in the survival of the ethnic group in the poverty-stricken and remote conditions (pp. 195-196). The investigation on the belief system of the Khmer at Phluang Village, Prasat District, Surin Province, revealed that their held beliefs were present in every aspect of life: conventional practices and personal characteristics, astrology, health, medicine, treatment, or natural phenomena (pp. 162-180). In the study on beliefs and ritual dances of Lao, Kui and Khmer in Surin Province, it was revealed that ethnic beliefs were applied to solve illness problems, indicating the connection between beliefs and cultural wisdom of the ethnic groups (pp. 198-201). To understand the livelihoods of Isan people, an investigation on the working culture of farmers at Phawon Village, Huay Thap Than District, Srisaket Province, was conducted. The findings revealed social structures of a rural farming society where fundamental beliefs were an important factor that influenced working culture, roles and responsibilities of family and community members (pp. 157-161). The survey report on art environment in Surin Province revealed that many stone sanctuaries, an ancient civilization heritage, had physical problems due to neglect, moisture and an intrusion of plant roots growing on them. Moreover, the areas where these ancient ruins were located had been invaded and transformed for commercial purposes, causing an environmentally eyesore due to an ignorance in local histories and cultures (pp. 202-286). The findings confirmed those on cultural perceptions of the students (pp. 113-116). Besides ancient ruins having historical connections, they also implicitly contained local legends and stories that younger generations should be encouraged to study (pp. 284-285).
