Purpose: To evaluate the incidence, contributing factors, and clinical results of refracture of proximal 5th metatarsal stress fracture treated operatively in athletes Materials and Methods: This study included 8 patients who had been treated for refracture of proximal 5th metatarsal stress fracture with operaton. Their charts & radiologic findings were evaluated retrospectively. Results: The overall incidence of refracture was 13%. Main contributing factors were time of return to sports activity and associated deformities such as cavus foot or flat foot. Seven cases were managed with nonoperative treatment, and we added percutaneous pin fixation under local anesthesia in one case. Bony union was seen at average 8. 5 weeks in 7 cases except 1 nonunion and all of 8 patient returned to athletics at average 16 weeks. Conclusion: The incidence of refracture of proximal 5th metatarsal stress fracture treated operatively in athletes was relatively high. Time of rerum to sports activity must be decided very carefully on individual situation and further imaging study may be helpful for bony union evaluation. The non-operative treatment may have a good result if bone graft was done initially.

Purpose : This study aimed to identify the educational effects of the International Development Cooperation and Healthcare course from 2018 to 2020. Methods : Changes in awareness of international development cooperation (understanding international development cooperation as well as government Official Development Assistance [ODA], thoughts on aid, and thoughts on government's aid scale) were analyzed using web-based surveys. The pre-course survey was conducted 1-2 weeks before the semester started, and the post-course survey was conducted 1-2 weeks after the semester ended. All data were analyzed using the SPSS 26.0 program, and statistical significance was set at p< .05. Results : A total of 314 people participated in the survey before taking the course, and 286 people participated in the survey after taking the course. Analysis of the changes in students' awareness of international development cooperation showed that all items (understanding international development cooperation and government ODA, as well as having thoughts on aid and government's aid scale) were improved. Regarding changes in awareness according to general characteristics, thoughts on aid were statistically significant according to all characteristics except for 2018. Regarding government's aid scale, awareness scores increased after taking the course in students who majored in healthcare, fine arts and athletics, broadcasting and media studies, and digital contents. Conclusion : This study showed that changes in awareness of international development cooperation were largest in second-year students. Compared to changes regarding international development cooperation, government ODA, and thoughts on aid, changes regarding thoughts on government's aid scale were minor. In the future, it is necessary to develop class content suitable for the first-year level and to supplement and operate content that can change the way of thinking on government's aid scale.
