This study investigates the effects of collocation task types on Korean high school students' collocation learning and learning attitudes. A total of 118 Korean high school students participated in the experiment, and they were divided into four groups: control group, receptive treatment group, productive treatment group and combination treatment group. In order to investigate the effects of collocation task types on students' English proficiency, each group of students was classified into a high proficiency group and a low proficiency group. The students took a pre-test before the experiment and a post-test after the experiment. After the post-test, the post-questionnaire survey was conducted to examine the students' learning attitudes. The results of the study were as follows: (1) The three types of collocation tasks were effective in learning receptive and productive collocations; (2) in the delayed retention test, it was revealed that the effect of the three types of collocation tasks on both receptive and productive collocation learning lasted; and (3) the result of post-questionnaire survey showed that learning collocation through collocation tasks had positive influence on most students in terms of raising their interest and increasing their self-confidence.
트랜스포터란 조선소에서 작업장 간에 조선 블록을 운반하는 장비이다. 트랜스포터 일정 계획을 효율적으로 하는 것은 선박 건조 과정에서 매우 중요한 역할을 한다. 블록 운반에 있어서의 트랜스포터 일정 계획에 관한 몇몇 연구들이 수행되었다. 이러한 연구들은 트랜스 포터 결합을 고려하지 않았다. 본 논문에서는 결합을 고려한 효율적인 트랜스포터 일정 계획 모형을 제안한다. 수리적 모형에서는 운영 비용 을 최소화하면서 트랜스포터 간의 작업 부하를 가능한 균등하게 하는 것을 목적으로 하였다. 또한 본 모형의 해를 탐색하기 위해 타부 서치 기반의 세 가지 휴리스틱 알고리즘을 제시하였으며 컴퓨터 실험을 통해 제안된 휴리스틱들의 효율성을 검증하였다.
