And we considered the necessary support for university students. We conducted a recording questionnaire to nine full-time staff members of A University who have many opportunities to interact with university students. Those members are between 20s to 50s and their student support experience was an average of 5 to 6 years. We analyzed seven comments concerning students in qualitative inducing way. Seven elements were picked out as results of the analysis. They were : [to grasp feature of the modern university students], [improve the environment to provide students with necessary support], [concrete correspondence to the situation], [conscious involvement of individual students],[concerning which thinks it was effective],[ influence to staff’s life] and[ view about concerning with a student]. A staff member, while getting into troubles dealing with a present university student, deepened his understanding toward this latter. Faculty members were able to take in charge university students according to ‘adult learning theory’. This support’s aim was to lead students to self-control. In this way, they cooperated with students to develop forward prospects for their university. Moreover, faculty members’ intervention will lead to an effective support for present university students., application/pdf}, pages = {27--33}, title = {卓球においてサービスがラリーに与える影響の定量化}, year = {}, yomi = {たまき, しょう and よしだ, かずと} }
