  • Causality mining in NLP is a significant area of interest, which benefits in many daily life applications, including decision making, business risk management, question answering, future event prediction, scenario generation, and information retrieval. Mining those causalities was a challenging and open problem for the prior non-statistical and statistical techniques using web sources that required hand-crafted linguistics patterns for feature engineering, which were subject to domain knowledge and required much human effort. Those studies overlooked implicit, ambiguous, and heterogeneous causality and focused on explicit causality mining. In contrast to statistical and non-statistical approaches, we present Bidirectional Encoder Representations from Transformers (BERT) integrated with Multi-level Feature Networks (MFN) for causality recognition, called BERT+MFN for causality recognition in noisy and informal web datasets without human-designed features. In our model, MFN consists of a three-column knowledge-oriented network (TC-KN), bi-LSTM, and Relation Network (RN) that mine causality information at the segment level. BERT captures semantic features at the word level. We perform experiments on Alternative Lexicalization (AltLexes) datasets. The experimental outcomes show that our model outperforms baseline causality and text mining techniques.

  • This study recruited 11 teachers with experience in guiding science exhibitions nationwide to investigate the perception and necessity of teachers as educational consumers of science exhibitions, one of the out-of-school science education activities, and conducted an in-depth written survey. An average of more than 3,600 characters answered a total of seven questions in writing, and through qualitative analysis, the growth of students and teachers due to participation in science exhibitions, difficulties in participating in competitions, and teachers' voices for revitalization were recognized. Teachers offered positive opinions in that participation in science exhibitions improves students' knowledge and attitudes related to science and experiences an open inquiry process linked to career advancement in science and engineering. However, the students who participated in the competition failed to record the contents of the inquiry in their school records, and instructors pointed out the obsession with discovering novel topics, the burden of guiding the inquiry process, and the limitations of their expertise in major knowledge. In order to revitalize science exhibitions, 17 city and provincial education offices called for measures to strengthen the capabilities of instructors and students, improve the promotion and screening methods of the National Science Museum, and improve the Ministry of Education's school records.

  • U.S. Congress established the Malcolm Baldrige National Quality Award (MBNQA) program in 1987 to recognize U.S. organizations for their achievements in quality and business performance and to raise awareness about the importance of quality and performance excellence as a competitive edge. The Baldrige Award was envisioned as a standard of excellence that would help U.S. organizations achieve world-class quality. Recently the U.S, Congress approved legislation that made education and health care organizations eligible to participate in the Award Program. These criteria are applied to evaluate two academic departments (Computer Science & Industrial Systems and Electrical Engineering) at Yonsei University. It was an informal evaluation performed by the undergraduate students who took quality Engineering course. Evaluated total scores turn out to be 522.5 and 548.5 for both, respectively. According to the MBNQA diagnosis, this level of score represents that there are some areas or work units which need to be improved. We hightlight them so that they can be used as feedback information.

  • The purpose of this study is to examine the perception of science educators (science research experts and science teachers) about invention education in science education. The instrument in surveying their perception consisted of the necessity of invention education in science education, the connection between invention and science education, and the demand for in-service invention education for science teachers. Subjects were 119 science educators (67 science teachers and 52 science research experts). They perceived positively about including invention educational content in school science education. They perceived that invention education was highly related to science education. Even though science educators have almost average level of understanding invention education, they demand in-service invention education for science teachers. Most of them referred informal courses to formal ones for school science education. Considering real life, engineering design, creative thinking in science education, invention method, and educational strategies can be effective for science education.

  • Korea is the 5th Maritime Power in the world, especially, Busan Metropolitan City is the 3rd Marine City, which has the largest Container port facility and logistic system in the world. However, Busan Citizen's maritime consciousness does not reach that level. This study points out the problems, which are insufficiency of linkage among maritime education institutes, uniformity of ocean education programs, incomplete ocean education system, inadequate management of ocean education programs and shortage of professional instructors. To solve these problems, it is necessary to develop the ocean education modules, establish the ocean education course and put into formal education course to maximize the education effectiveness. This is for the improvement of the reputation as a Marine City Busan, construction the hydrophil culture and propagation of ocean culture.

  • This study aims to investigate the kinds of content and science communication included in the exhibits and the exhibition panels in order to suggest a direction of desirable educational development in the nuclear power information halls in Korea. The four local nuclear power information halls in Korea and the nuclear power science center in Japan are selected as the subject. The results of this study show that the 'conceptual' exhibits are a dominant topic among the four topics of contents, and the concept (CON) and interest (INT) are found as the most dominating component of science communication. Meanwhile, the nature of science (NOS), awareness (AW), enjoyment (ENJ), and opinion (OP) components are little exhibited. The findings of this study indicate that the nuclear power information halls can be more professional to enhance scientific literacy, as the informal education institutions, providing information of nuclear energy and radiation on various perspectives for visitors to make decisions by themselves and to improve their scientific attitudes and understanding of science communication. In addition, the limited science communication can be fully reinforced by docents or commentators. Further research needs to investigate the development of a specialized program to produce professional docents or commentators.

  • This study aimed to find the mediating impact of entrepreneurial education during COVID-19 on entrepreneurial intention among university students from major cities of Pakistan. Majority of businesses shifted to online from offline mode as a result of COVID-19 pandemic. This created a great opportunity for university students to become entrepreneurs without much investment during COVID-19. Primary data for this study was collected with the help of an adopted questionnaire from previous studies. An online survey was considered appropriate due to the COVID-19 situation in the country. The number of data samples collected from the major cities of Pakistan was 460. The research hypothesis was tested with the help of SmartPLS by using least square structural equation modeling. Findings revealed there is full mediation of entrepreneurial education during COVID-19 between the self-efficacy, subjective norms, and attitude towards entrepreneurship for entrepreneurial intention during COVID-19 among university students. Therefore, the research confirmed the application of the theory of planned behavior among university students in Pakistan with regards to factors such as self-efficacy, subjective norms, attitude towards entrepreneurship and entrepreneurial intention. The present study also concludes that all students regardless of their area of study such as Business and Engineering look forward to become entrepreneurs during COVID-19. The students opting for entrepreneurship had either formal or informal entrepreneurial education during COVID-19.

  • Informal engineering education program for high school students was developed to cultivate engineering literacy using the human resources and facilities of university. Plant factory, a smart farming technology, was selected as a main theme, and the novel engineering camp program involving engineering design activities and intra-linter-team works was planned. The camp program was applied to 38 high school students in an active learning classroom. Five teams were constructed according to elemental technologies such as biotechnology, information-communication technology, energy engineering, mechanical engineering and architectural engineering, and the students were participated in intra- and inter-team activities to achieve the final goal of 'the construction of a plant factory in school'. The team works were conducted according to the eight steps of engineering design process (identifying the problem and need, identifying criteria and constraints, brainstorming possible solutions, selecting the best possible solution, constructing a prototype, testing and evaluating the solution, communicating the solution, and refining design). Participants' satisfaction survey showed that the satisfaction on the contents of engineering design was 4.48 on 5-point Likert scale. The participants' satisfaction on creative activity and systematic methodology was 4.43 on 5-point Likert scale. 97% of participants responded positively to team works, and 92% of participants were satisfied with career mentoring activity supplied by undergraduate/graduate students. These results indicates that the engineering camp program involving engineering design activity and intra-/inter-team works can contribute to cultivate engineering literacy such as creativity, problem solving ability, collaboration, communication skills for high school students, and to increase their interests in engineering fields.

  • The Center for Nanotechnology in Society at Arizona State University (CNS-ASU) is a Nano-scale Science and Engineering Center (NSEC) funded by the US National Science Foundation (NSF). It implements an agenda of "real-time technology assessment" (RTTA) in pursuit of a strategic vision of the "anticipatory governance" of nanotechnologies. To achieve this vision, CNS-ASU unifies research programs not only across several universities but also across three critical, component activities: foresight (of plausible future scenarios), integration (of social science and humanities research with nano-scale science and engineering), and engagement (of publics in deliberations). CNS-ASU also performs educational and training activities as well as public outreach and informal science education. This paper elaborates the Center's strategic vision of anticipatory governance and its component activities, especially in the context of extending the concerns of societal dimensions research beyond the traditional risk paradigm.
