최근 사전학습 언어모델에 내재된 지식을 최대한으로 활용하고자 태스크에 대한 설명을 입력으로 주는 manual prompt tuning 방법과 자연어 대신 학습가능한 파라미터로 태스크에 대한 이해를 돕는 soft prompt tuning 방법론이 자연어처리 분야에서 활발히 연구가 진행되고 있다. 이에 본 연구에서는 페르소나 대화 생성 태스크에서 encoder-decoder 구조 기반의 사전학습 언어모델 BART를 활용하여 manual prompt tuning 및 soft prompt tuning 방법을 고안하고, 파인튜닝과의 성능을 비교한다. 전체 학습 데이터에 대한 실험 뿐 아니라, few-shot 세팅에서의 성능을 확인한다.

This study examined the effects of prompts, environmental alteration, and feedback on reduction of food wastes. The study was conducted at a student restaurant at a university. Subjects in this study were college students, faculty members and administrative staffs at the university. An A-BC-BCD-BC within subject design was employed. After baseline phase(A), prompts and environmental alteration were manipulated in the second phase(BC). In the next phase(BCD), feedback was added in addition to the prompts and environmental alteration. In the last phase(B), all the treatments except environmental alteration were withdrawn. The dependent variables n cluded (1) total weight of food waste per day, (2), the weight of food waster per person, (3) the ratio of food waste to total food served per day, (4) total amount of monetary value for food waste to total food served per day. The results indicated that prompts and environmental alteration were affective in reducing food wastes. Thus, measures of all the dependent variables decreased when environmental alteration and prompts were manupulated. However, when feedbacks were added to prompts and environmental alteration, the additional effect of feedback was not observed. The implications and limitations of these findings were discussed and the directions of future studies were also proposed.

This study examined the effect of environmental alteration and prompts on recycling behavior. An A-B-BC with a control condition design was employed. Subjects in this study were college students, professors, and employees at a university building. After a baseline phase, environmental alteration was I effect in the next phase and both environmental alteration and prompts were in effect in the final phase for the control condition. The environmental alteration consisted of providing four separation containers for the paper cups, cans recyclable paper, and the disposable on each floor in the building. The prompts consisted of providing the information about the importance of environmental preservation and how to separate the materials in the appropriate containers using an information board and pamphlets. The dependent variables were (1) the number of cans collected in can container, (2) the number of paper cups collected in cup container, (3) the rate of correct separation of cans, (4) the rate of correct separation of paper cups, and (5) the weight of disposable. The rates of correct separations of cans and paper cups were obtained by calculating the percentage of thenumber of recyclable cans and paper cups in the corresponding containers. The results indicated that environmental alteration had positive effects on all the dependent variables. Also, when the prompts were added to the environmental alteration, the incremental effect of the prompts was demonstrated. The implications and limitations of theses findings were discussed and the direction of future studies was also proposed.
