본 연구는 대학생의 혁신행동과 학업만족에 대한 중요성과 이에 대한 선행요인으로 셀프리더십 및 창의적인성에 대한 연구부족을 인식하면서, 셀프리더십, 창의적 인성, 혁신행동 및 학업만족간의 구조적 관계를 실증 분석하였다. 연구목적을 달성하기 위해 본 연구는 서울, 충북, 영남지역의 대학에서 경영학 강좌를 수강하는 1~4학년 학생 176명의 응답을 표본으로 구조방정식을 이용하여 검증하였다. 연구결과, 셀프 리더십은 창의적 인성, 혁신행동과 학업만족에 정(+)의 영향을 미치는 것으로 나타났다. 또한 창의적 인성은 혁신행동에 정(+)의 영향을 미치는 것으로 나타났으나 학업만족은 혁신행동에 영향을 주지 않는 것으로 나타났다. 이에 따라 창의적 인성은 셀프 리더십과 혁신행동 간의 관계에서 부분매개 역할을 하는 것으로 나타났다. 본 연구는 대학생들의 개인특성 중 셀프 리더십과 창의적 인성이 혁신행동과 학업만족에 영향을 주는 모형을 처음으로 제시하였다. 본 연구는 실무적으로 대학생의 혁신행동과 학업만족의 수준을 제고하기 위해 개인의 특성을 이해하고 배려하는 자율적이고 창의적인 대학조직 환경조성 등이 필요함을 시사한다. 이러한 연구결과를 바탕으로 시사점과 연구의 한계점 및 향후 연구방향이 논의되었다.

정보통신기술 및 교육패러다임 변화와 맞물려 이러닝을 활용한 직업교육훈련은 그동안 몇 차례 굵직한 변화를 겪어 왔다. 이러닝을 통한 직업능력개발의 트렌드는 학습의 모바일화, 짧은 콘텐츠의 증가, 학습경험제공의 민첩성과 현장 밀착성으로 요약 가능한 가운데, 본 연구는 이러닝을 통한 직업교육훈련 대상자들의 학습동기, 교육구성요소에 대한 중요성 인식, 학습 행태에 대한 조사연구를 실시하였다. 6개 훈련기관의 4,021명이 참여한 설문조사 응답을 분석한 결과, 자발적 자기계발 차원의 학습이 회사의 직무교육차원보다 높게 나타났고, 이러닝의 구성요소 중에서는 학습내용이 가장 중요한 것으로 나타나, 기존의 형식에 치우진 교육콘텐츠 개발이나 훈련평가가 보다 내용 중심적으로 변화해야함을 시사하였다. 학습 행태측면에서도 학습장소와 시간 활용이 보다 융통적으로 변화하였고, 시간을 정해놓지 않고 틈틈이 불규칙적으로, 특정시점에 몰아서 학습하는 추세를 확인할 수 있었다.

Various approaches have been applied to transform aquaculture from a manual, labour-intensive industry to one dependent on automation technologies in the era of the fourth industrial revolution. Technologies associated with the monitoring of physical condition have successfully been applied in most aquafarm facilities; however, real-time biological monitoring systems that can observe fish condition and behaviour are still required. In this study, we used a video recorder placed on top of a fish tank to observe the swimming patterns of rock bream (Oplegnathus fasciatus), first one fish alone and then a group of five fish. Rock bream in the video samples were successfully identified using the you-only-look-once v3 algorithm, which is based on the Darknet-53 convolutional neural network. In addition to recordings of swimming behaviour under normal conditions, the swimming patterns of fish under abnormal conditions were recorded on adding an anaesthetic or lowering the salinity. The abnormal conditions led to changes in the velocity of movement (3.8 ± 0.6 cm/s) involving an initial rapid increase in speed (up to 16.5 ± 3.0 cm/s, upon 2-phenoxyethanol treatment) before the fish stopped moving, as well as changing from swimming upright to dying lying on their sides. Machine learning was applied to datasets consisting of normal or abnormal behaviour patterns, to evaluate the fish behaviour. The proposed algorithm showed a high accuracy (98.1%) in discriminating normal and abnormal rock bream behaviour. We conclude that artificial intelligence-based detection of abnormal behaviour can be applied to develop an automatic bio-management system for use in the aquaculture industry.

Objectives: Although evidence-based medicine (EBM) is a useful method for integrating evidence into the decision-making process of occupational physicians, occupational physicians lack EBM knowledge and skills, and do not have the time to learn the EBM method. In order to enable them to educate themselves at the time and place they prefer, we designed an electronic EBM course. We studied the feasibility and utility of the course as well as its effectiveness in increasing EBM knowledge, skills, and behaviour. Methods: Occupational physicians from various countries were included in a within-subjects study. Measurements were conducted on participants' EBM knowledge, skills, behaviour, and determinants of behaviour at baseline, directly after finishing the course and 2 months later (n = 36). The feasibility and utility of the course were evaluated directly after the course (n = 42). Results: The course is applicable as an introductory course on EBM for occupational physicians in various countries. The course is effective in enhancing EBM knowledge and self-efficacy in practising EBM. No significant effect was found on EBM skills, behaviour, and determinants of behaviour. After the course, more occupational physicians use the international journals to solve a case. Conclusion: An electronic introductory EBM course is suitable for occupational physicians. Although it is an effective method for increasing EBM knowledge, it does not seem effective in improving skills and behaviour. We recommend integrating e-learning courses with blended learning, where it can be used side by side with other educational methods that are effective in changing behaviour.

유비쿼터스 환경에서 학습자 맞춤형 교육을 제공하기 위해서는 학습자의 학습행위에 대한 분석이 필수적이다. SCORM(Sharable Contents Object Reference Model), IMS LD(Instructional Management System Learning Design) 등의 표준은 진도 체크와 같은 학습 설계 지원 기능을 제공한다. 하지만 표준 적용은 개발의 어려움과 수정이 어렵다는 단점이 있다. 본 논문에서는 이벤트 가로채기를 사용하여 웹 브라우저에서 학습자의 행위를 관리하는 시스템을 구현한다. 이를 통해 HTML기반의 모든 콘텐츠를 추가적인 작업 없이 재활용할 수 있고 학습결과의 저장 및 분석이 가능하게 되어 표준 적용에 따른 문제점을 개선할 수 있다. 또한 네트워크 단절 시에도 학습결과를 추적할 수 있어 유비쿼터스 학습 환경을 지원할 수 있다.

All the aspects of human life have been affected by the novel coronavirus (Covid-19). It has rapidly spread in most countries including the Kingdom of Saudi Arabia. As a result, early precautionary actions aiming to minimise the virus effect are taken by the Saudi government. One of these actions is the sudden shift to online classes and suspending the attendees to all educational institutes. Such immediate change can have a significant effect on the educational process, especially for students. One can argue that students' information-seeking behaviour within the current situation can affect their learning quality and outcomes. Therefore, this paper examines the Saudi students' information-seeking behaviour by taking a sample of students from Umm Al-Qura University. A descriptive analysis is conducted with 193 students and two approaches are used to collect data, questionnaire and semi-structured interview. The results showed that the majority of students face difficulties when searching and retrieving e-resources from the university library website. The problems range from mainly poor User Experience (UX), network connection, multiple errors and lack of subscription with academic publishers.

This research aimed for revealing social interaction-based environmental learning elements at the natural history museum. First, we carried out a survey of the perceptual change about 'the environment' concept. It was for confirming whether environmental learning occurred in visiting. Second, we found environmental learning elements through analyzing dialogues among small group members during looking around the museum. Social interaction-based environmental learning elements were classified into five; knowledge, affection, value, skill, behaviour. Each environmental learning element included several sub-elements, so we revealed totally 9 environmental learning sub-elements. By results, we said characteristics and possibility of the natural history museum as an informal environmental educational institution. It is meaningful for extending areas of environmental education.

Most existing research into the metacognitive approach in mathematics learning has been concentrated mainly in the study of phenomena of metacognitive (including the affective) behaviour in the context of mathematical problem solving or more broadly mathematical content-elated learning. However, this study originally constructs the concept of "macroscopic metacognition" which could be differentiated with general metacognition, and draws out macroscopic-metacognitive factors among the elementary and middle school students through individual interview. Questionnaire research is executed to find out how the macroscopic metacognition is included into the students' mathematics learning and the relationship between their mathematics learning accomplishment and macroscopic metacognition. Thus, a considerable degree of the positive relationship between these two variables was found out.

In this paper we develope a hybrid learning rule to improve the robustness of multi-layer Perceptions. In most neural networks the activation of a neuron is deternined by a nonlinear transformation of the weighted sum of inputs to the neurons. Investigating the behaviour of activations of hidden layer neurons a new learning algorithm is developed for improved robustness for multi-layer Perceptrons. Unlike other methods which reduce the network complexity by putting restrictions on synaptic weights our method based on error-backpropagation increases the complexity of the underlying proplem by imposing it saturation requirement on hidden layer neurons. We also found that the additional gradient-descent term for the requirement corresponds to the Hebbian rule and our algorithm incorporates the Hebbian learning rule into the error back-propagation rule. Computer simulation demonstrates fast learning convergence as well as improved robustness for classification and hetero-association of patterns.
