ABSTRACT
Objectives@#The purpose was to identify the ingredients that are usually surveyed for assessing real prices and to present the demand for such surveys by nutrition teachers and dietitians for ingredients used by school foodservice. @*Methods@#A survey was conducted online from December 2019 to January 2020. The survey questionnaire was distributed to 1,158 nutrition teachers and dietitians from elementary, middle, and high schools nationwide, and 439 (37.9% return rate) of the 1,158 were collected and used for data analysis. @*Results@#The ingredients which were investigated for price realities directly by schools were industrial products in 228 schools (51.8%), fruits in 169 schools (38.4%), and specialty crops in 166 schools (37.7%). Moreover, nutrition teachers and dietitians in elementary, middle, and high schools searched in different ways for the real prices of ingredients. In elementary schools, there was a high demand for price information about grains, vegetables or root and tuber crops, special crops, fruits, eggs, fishes, and organic and locally grown ingredients by the School Foodservice Support Centers. Real price information about meats, industrial products, and pickled processed products were sought from the external specialized institutions. In addition, nutrition teachers and dietitians in middle and high schools wanted to obtain prices of all of the ingredients from the Offices of Education or the District Office of Education. @*Conclusions@#Schools want to efficiently use the time or money spent on research for the real prices of ingredients through reputable organizations or to co-work with other nutrition teachers and dietitians. The results of this study will be useful in understanding the current status of the surveys carried out to determine the real price information for ingredients used by the school foodservice.

ABSTRACT
BACKGROUND: We investigated the clinical outcome in patients whose cavitary bone defects were treated with beta-tricalcium phosphate (β-TCP) after surgical removal of benign tumors. METHODS: Between March 2015 and December 2015, 20 patients who underwent operation for bone tumors were enrolled into this study and prospectively followed up for a median period of 28.1 months. RESULTS: When the radiographic sign of complete resorption was defined as greater than 50% resorption of the allograft material accompanied by bone remodeling until 12 months, 55% of patients had complete resorption. Positive correlation between the filling volume and time needed for complete resorption was not found (p = 0.184). CONCLUSIONS: Purified β-TCP could be a suitable choice as a bone graft substitute after the removal of benign bone tumors.
