Results: The respondent group exhibited prevailing Artistic, Investigative, and Conventional types, with a slightly higher number of introverts.
Conclusions: Personalities of the respondents fit into the job environment quite well, which could positively influence their interaction with patrons and the overall quality of work. 相似文献
