Many poly (vinyl chloride: PVC) membrane electrodes were investigated for the determination of basic drugs, chlorpromazine, amitriptyline, nortriptyline, etc. These electrodes are based on the use of the ion-association complexes of the basic drugs with eriochrome cyanine R, chromoxane cyanine, chrome azurol S and picric acid as ion-exchange sites in a plasticized PVC matrix. All ion-exchangers except picrate complex were not proper for use, because those complexes in plasticized membrane were excluded into aqueous working solution. These drug electodes show excellent Nernstian responses in the concentration range 10-2~10-6. Their selectivity with respect to each other, as well as their workable pH range have been investigated. The major advantages of the proposed methods are their simplicity and speed.

이지연 ( Lee Ji Yeun ),최진화 ( Choi Jin Hwa ) 미래유아교육학회 2018 미래유아교육학회지 Vol.25 No.3

The purpose of this study was to investigate the mediating effects of self-leadership between the child care teacher’s perfectionism and the role performing ability. For data collecting, 235 child care teachers who are working for day care center in J area were involved. The SPSS 20.0 was used for statistical analysis. The perfectionism scale was used for independent variable, self-leadership scale for mediator, and role performing ability scale for dependent variable. The major findings were as follows: First, among the three subfactors of the child care teacher’s perfectionism, the self-oriented and other-oriented perfectionism showed significantly positive effect on the role performing ability and the self-leadership. However, the socially-prescribed perfectionism was not significant. Second, the pure self-oriented perfectionism that eliminated the other-oriented perfectionism predicted the role performing ability. However, the pure other-oriented perfectionism that eliminated the effect of the self-oriented perfectionism did not predict the role performing ability. Third, there was mediating effect of the self-leadership between the self/other-oriented perfectionism and the role performing ability. This study was important in illuminating the facts that the child care teacher’s perfectionism had an effects on role performing ability and the self-leadership acted as mediator between the child care teacher’s perfectionism and the role performing ability.
