본 연구에서 연구자는 직업기술 교수 상황에서 효과적으로 적용할 수 있는 강화 조건과강화제 유형을 분석하기 위해 실험을 진행하였다. H 특수학교 학생 2명이 연구에 참여하였으며, 독립변인과 종속변인간의 기능적 관계를 분석하기 위해 지연된 대상자간 중다기초선설계법을 사용하였다. 연구자는 종속변인으로 10개의 볼트와 너트 5세트를 조립하는데 필요한 지속시간을 측정하였으며, 독립변인으로 강화 조건과 강화제 유형에 따라 즉각·분산 강화 조건-소모성 강화제, 즉각·분산 강화 조건-조작성 강화제, 지연·누적 강화 조건-소모성 강화제, 지연·누적 강화 조건-조작성 강화제의 총 4가지 서로 다른 중재단계를 제시하였다. 중재는 약 3주에 걸쳐 주 2회 실시되었다. 실험 결과에 따르면 연구 대상자별 강화 조건과 강화제 유형에 따른 직업기술 과제 수행 시간의 변화가 다르게 나타났다. 하지만 모든 연구대상자는 강화를 제공하는 중재단계에서 기초선에 비해 짧은 시간에 주어진 직업기술 과제를 완수하였다. This study analyzed the effects of reinforecment conditions and types of reinforcers on the fluency of the vocational tasks for 2 students with disabilities who were enrolled at a special education school. A delayed multiple baseline across participants design was employed to investigate a potential functional relation between the dependent and independent variables. The intervention was conducted twice a week for three weeks. The experimental results showed that the implementation of reinforcement resulted in the higher rate of the correct vocational responses with a shorter amount time of task completion. However, no significant differences were not observed accroding to the types of reinforcement conditions (i.e., immediate-distributed vs. delayed-accumulated reinforcement conditions) and reinfercers (i.e., consumable vs. manipulative reinforcers).

최진혁(Choi, Jin-Hyeok),이태희(Lee, Tae-Hee),박태성(Park, Tae-Sung),유영성(Yoo, Young-Sung) 한국신재생에너지학회 2009 신재생에너지 Vol.5 No.1

To improve the performance of the anode-supported Solid Oxide Fuel Cell (SOFC) which can be operated at an intermediate temperature, the functional layer (FL) is introduced on a anode substrate. And the scandia-stabilized zirconia (ScSZ) and samaria-doped ceria (SDC) which have higher ionic conductivity and better chemical stability than yttria-stabilized zirconia (YSZ) are used as material for the anode FL with the Ni, The fabrication process of anode-supported single cell with the anode FL was established and the power density of those was evaluated. As a result, the sample with anode FL (Ni-YSZ) has higher power density than normal cell. The single cell which was composed of the FL (Ni-YSZ) and electrolyte (YSZ) showed about 550mW/cm² of the maximum power density at 650?C and 1430mW/cm² at 750?C respectively, In case of the single cell using the ScSZ and SDC as anode FL, the performance of samples decreased rapidly and those showed unstable voltage during long-term test. In case of using methane as a fuel, the cell performance with each FL decreased comparing with H₂ fuel. In the region of a high current density, there are large concentration polarizations.

최진혁 ( Jin Hyeok Choi ) 한국특수아동학회 2015 특수아동교육연구 Vol.17 No.1

The main purpose of this study was to analyze the effects of training three students diagnosed with autism spectrum disorder to tutor their peers using the Teacher Performance Rate and Accuracy observation procedure (TPRA) as base of assessment on the acquisition of the observational learning capability. A time-lagged multiple probe across participants design was employed for this study. The dependent variables were the number of correct responses to observational learning probe trials in which the target participants observed direct Learn Units delivered to their peer confederates and then were probed for the correct responses to the indirect Learn Units. The independent variable was the mastery of tutor training as assessed through the TPRA. One pre-intervention probe session was conducted prior to the implementation of the intervention. After the participant finished the intervention session according to the pre-determined mastery criterion, two additional post-intervention sessions were conducted. Each probe and intervention session lasted approximately 20-30 min. Results showed that the numbers of correct responses to indirect Learn Units significantly increased following tutor training for three target participants. Additionally the number of echoic responses by the target participants of their peer confederates’ responses considerably increased.
