Asynchronous Learning Networks (ALN) has become a kind of prevalent information systems to supplement or even substitute a traditional classroom face-to-face teaching method. In this paper, we investigate the impacts of types of courses, lecturers' instruction models and computer self-efficacy on the ALN effectiveness in teaching from lecturers' perspective. We conducted survey to professors in various faculties such as School of Computing, Faculty of Arts, Science, Business, Law and Engineering in the National University of Singapore. According to the responses from ninety-eight professors, instruction modes positively influence the usage of ALN; types of course and lecturers' computer-efficacy influence lectures' satisfaction of ALN in teaching. Both the usage of ALN and satisfaction of ALN positively influence the effectiveness of ALN. The results of this study fill the gap of ALN researches in education by examining it from lecturers' perspective and enable schools to improve their implementation of ALN systems based on our findings.

Purpose: This study was conducted to identify the relationships between the perceived and actual achievement on skill performance assessment and identify the relation to learning motivation factors. Methods: A total of 80 senior nursing students currently studying at a university participated in the study in 2015. Students completed a performance examination of 20 nursing skills at the end of their 7-week training period; their performance was rated using checklists. Students then completed a survey, which included questions about learning motivation and perceived achievement level. Data were analyzed by descriptive statistics, Pearson's correlation, and Kruskal-Wallis test. Results: There was a weak correlation between perceived and actual achievement. Intrinsic and extrinsic goal-orientation and self-efficacy in learning motivation factors was significantly correlated to perceived achievement. Perceived achievement and self-efficacy in middle quartile of actual achievement were higher than other upper- or lower-quartile group. Conclusion: The findings suggest that the motivation factors of learners should be taken into account to maximize academic achievement in nursing skills training. In addition, it should be considered a strategy to reduce the gap between perceived and actual achievement.

In data-driven learning (DDL), learners explore a corpus to understand vocabulary and grammar. Although many studies have emphasized the role of DDL in second language (L2) acquisition, L2 light verbs have been largely under-explored. To bridge this gap, this study focused on the learning outcomes of L2 light verbs among 29 intermediate-level Japanese university students. The research zeroed in on six prevalent light verbs in English: "make," "do," "take," "have," "give," and "get." Over nine weeks, the participants engaged with verb-noun collocations using worksheets that juxtaposed Japanese translations of the target collocations with their English equivalents, with the verbs omitted. With the aid of Wordbanks Online, they filled in the blanks and constructed accurate sentences. Before this activity, a 20-minute tutorial was given to the participants on how to interpret the concordance lines. The effectiveness of the DDL method was evaluated using pre-tests, immediate post-tests, and delayed post-tests. The results showed that DDL significantly improved the participants' knowledge of the target collocations of light verbs and nouns; the post-test and delayed post-test scores were significantly higher than the pre-test scores. The results showed that, overall, DDL contributed to memorizing the collocations of light verbs and nouns; however, DDL had different effects on the memorization of collocations across different light verbs. The extent of work on the worksheet is not the only factor in its retention, and observing concordance lines may promote learners' memorization of light-verb collocations.

원활한 교통의 흐름은 현대 사회에서 매우 중요한 요소이며, 교통체증은 환경 및 경제 등 다양한 형태로 문제를 초래했다. 이러한 문제를 해결하기 위해 최근 인공지능을 활용한 지능형교통체계(Intelligent Transport System)가 주목받고 있다. 본 논문에서는 강화학습 기법을 활용하여 교차로 각 방향의 차량과 보행자를 동시에 고려하여 교통의 흐름을 원활하게 하면서 동시에 불만족도를 낮출 수 있는 알고리즘을 제안한다. 제안하는 알고리즘을 적용한 교차로 신호체계 시뮬레이션 결과, 기존의 고정형 신호체계에 비해 차량·보행자의 불만족도를 상당히 낮출 수 있으며, 교차로의 교차하는 도로의 수가 많을수록 성능의 차이가 증가함을 확인하였다.

Recently, mobile manipulators have been utilized in agriculture industry for weed removal and harvest automation. This paper proposes a domain adaptive fruit detection method for harvest automation, by utilizing OWL-ViT model which is an open-vocabulary object detection model. The vision-language model can detect objects based on text prompt, and therefore, it can be extended to detect objects of undefined categories. In the development of deep learning models for real-world problems, constructing a large-scale labeled dataset is a time-consuming task and heavily relies on human effort. To reduce the labor-intensive workload, we utilized a large-scale public dataset as a source domain data and employed a domain adaptation method. Adversarial learning was conducted between a domain discriminator and feature extractor to reduce the gap between the distribution of feature vectors from the source domain and our target domain data. We collected a target domain dataset in a real-like environment and conducted experiments to demonstrate the effectiveness of the proposed method. In experiments, the domain adaptation method improved the AP50 metric from 38.88% to 78.59% for detecting objects within the range of 2m, and we achieved 81.7% of manipulation success rate.

The present study aims to present a comprehensive understanding of the performance of neighboring multi-story buildings with different dynamic characteristics under blast loads. Two different scenarios are simulated in terms of explosion locations with respect to both buildings. To investigate the effect of interaction between the neighboring buildings in terms of the induced responses, the separation gap is set to be sufficiently small to ensure collisions between stories. An adequately large separation gap is set between the buildings to explore responses without collisions under the applied blast loads. Several blast loads with different peak pressure intensities are employed to perform the dynamic analysis. The finite-element toolbox Computer Aided Learning of the Finite-Element Method (CALFEM) is used to develop a MATLAB code to perform the simulation analysis. The dynamic responses obtained in the scenarios considered herein are presented comparatively. It is found that the obtained stories' responses are governed mainly by the location and intensity of the applied blast loads, separation distances, and flexibility of the attacked structures. Moreover, explosions near a light and flexible building may lead to a significant decrease in blast resistance because explosions severely influence the dynamic responses of the building's stories.

그동안의 소프트웨어교육과 타 교과의 연계 융합에 대한 연구는 주로 수학과 과학교과에 편중되어왔다. 이는 학생의 교과에 대한 다양한 선호와 학습 성격 유형 등을 만족시키지 못하여 학습 격차를 유발할 수 있다. 뿐만 아니라, 컴퓨팅 사고를 적용할 수 있는 다양한 융 복합적 문제의 해결과정을 다루어야 함을 감안할 때 바람직하지 않다. 그리하여 기존의 수학과학적 접근에서 벗어난 언어적인 접근인 영어교과와의 연계를 통해 학생들의 다양한 성향과 선호를 포용하고, 영어교과와 소프트웨어교육의 새로운 언어를 배우는 과정과 방법상의 유사점을 접목시켜 교육 효과의 향상을 도모하고자 하였다. 이를 위하여 초등 영어교과와 소프트웨어교육의 교수학습모델 분석을 토대로 연계에 적합하도록 기존의 영어교과와 소프트웨어 교수학습모델을 변형하여 수업모형을 개발하였다. 이후 초등학교 영어교과내용 중 소프트웨어교육에 적용 가능한 학습 요소를 추출하여 개발된 수업모형에 적용한 프로그램을 설계하여 실제적인 학습 활용 방안을 모색하였다.
