The purpose of this study is to propose the direction of university unification education by analyzing the influence of unification perception of university students on the intention of unification education. Many studies have shown that current students are more likely to perceive the need for unification at the normative level or legitimate unification in the recognition of unification at the practical level in relation to individual interests. Understanding the impact of university students' unification perception on the attendance of unification education is necessary to establish the appropriate educational direction for university students. To this end, hierarchical regression analysis is conducted with ideological disposition, support for unification, interest in unification, and national homogeneity as independent variables, and the intention of attending unification education as a dependent variable. As a result, it is found that unification support position, unification interest, unification concern position, and national homogeneity have influences on college students. These results can be understood as meaning that the utilitarian recognition of unification influences college students' decisions to undergo unification education. Based on the analysis results and implications, the direction of unification education is suggested.

We examine the mechanism of SN2 fluorination promoted by a pyrene-tagged ionic liquid (PIL). Comparison is made for contact ion-pair (CIP) vs. solvent-separated ion-pair (SSIP) mechanism by calculating the Gibbs free energies of pre-reaction complexes and Gibbs free energies of activation G? for both processes. We find that the CIP mechanism is preferred for [PIL + MF + C3H7OMs] (M = Cs, K) system. SN2 fluorination of the [1-Butyl-3-methylimidazolium (bmim)-CsF] system is also studied in order to estimate the efficacy of PIL vs. more conventional ionic liquid [bmim][OMs]. The better promotion of the reaction by PIL is attributed to π interactions between the metal cation and pyrene, giving G? that is smaller (by approximately 1.3 kcal/mol) than that for the [bmim-CsF] system, in excellent agreement with experimental observations.
