tations before the event were high (Q1, 5.42 ± 0.89; Q2, 4.98 ± 1.02; Q3, 5.02 ± 0.96), and so was their level of satisfaction after the event (Q4, 5.44 ± 0.78; Q5, 4.64 ± 1.17; Q6, 5.19 ± 0.87; Q7, 5.04 ± 0.93; Q8, 5.18 ± 0.89; Q9, 5.42 ± 0.77). Examining the relationships between the scores for nine answers each respondent gave showed that they were positively correlated with each other (r = 0.30 to 0.67, p < 0.01) except for Q2-Q7and Q2-Q8 (r = 0.19, 0.26, n.s.).

... s were preferred? Respondents of all age classes preferred symposia over six alternatives, while on-demand lectures and exhibitions were less preferred (Figure 3) . The preference for "science cafés," which involve face-to-face presentations and conversations in casual settings, varied according to age: it was strong in the 30's group (0.70), while weak in the 60's group (0.18) (χ² (6) = 15.23, p < 0.05). In contrast, the preference for "extension lectures," special courses usually offered by universities as social contributions, was strong in older generations (40's-70's+), while weak in younger generations (10's-30's) (χ² (6) = 17.71, p < 0.01).
