Technological opportunity discovery for technological convergence based on the prediction of technology knowledge flow in a citation network     

Inchae Park  Byungun Yoon 《Journal of Informetrics》2018,12(4):1199-1222

As technological convergence has recently become a mainstream innovation trend, technological opportunities need to be explored in heterogeneous technology fields. Most of the previous convergence studies have taken a retrospective view in measuring the degree of convergence and monitoring the converging trends. This paper proposes a quantitative future-oriented approach to technological opportunity discovery for convergence using patent information. In a future-oriented approach, technological opportunities for convergence are suggested by predicting potential technological knowledge flows (TKFs) between heterogeneous fields. The potential TKFs are predicted by a link prediction method in a directed network, which is suggested in this paper to represent the direction of the predicted TKFs by adapting the concept of bibliographic coupling and edge-betweenness centrality. Converging technological opportunities are proposed as incremental and radical technological opportunities by extracting the potential increased knowledge flow links and emerging knowledge flow links. Moreover, the direction and themes of the predicted potential TKFs are provided as technological opportunities for convergence. As an illustration of the proposed method, the technological opportunities between biotechnology (BT) and information technology (IT) are explored. Firms and researchers can use the proposed method to seek out new technological opportunities from various technologies so that R&D policymakers can plan new R&D projects on technological convergence.  相似文献   

Haunted Trauma Narratives of Inclusion,Race, and Disability in a School Community     

Irene H. Yoon 《Educational Studies A Journal of the American Educational Studies Association》2019,55(4):420-435

By typical definitions in the special education world, inclusion would not be recognizable as it exists at Memorial Elementary. Memorial is responding to a widely documented trend in public schools: over-representation of students of color, particularly Black and Brown students, in high-incidence special education categories, including emotional and behavioral disabilities (EBD). I conceptualize EBD as unacknowledged suppression of hauntings from transgenerational trauma—legacies of institutional racism, poverty, and attempts at dehumanization. My primary hypothesis is that Memorial’s practice and ethic of unconditional belonging has been a transformation afforded by being haunted. I argue that haunted trauma narratives affirm and reconstruct the personhood of students of color with ghosts of trauma. Through narrativizing, students of color and educators rebuild inclusion from difference-as-allowed toward Martin Luther King Jr.’s (2001) “beloved community” (p. 458). That is, Memorial has redesigned school structures, educators’ beliefs and practices, interactions with children and their families, and other aspects of everyday systems to be organized around the intersections of race, trauma, identity, and community. Though dreaming is undeniably difficult, Memorial also illustrates the transformative power of affective forces from ghosts that demand hope, justice, and healing.  相似文献   

Are model PISA pupils happy at school? Quality of school life of adolescents in Finland and Korea     

Junghyun Yoon  Tero Järvinen 《比较教育学》2016,52(4):427-448

This paper explores the quality of school life (QSL) of two ‘model pupils’ in Programme for International Student Assessment (PISA) tests, Finland and Korea, and investigates students’ views on the central aspects of QSL (general satisfaction, peer relations and teacher–student relations) using PISA 2012 data. It also seeks to interpret how specific institutional and sociocultural aspects are linked to QSL. The analyses show that Finnish and Korean adolescents’ views on QSL are less positive compared with the OECD average; Finnish adolescents’ views on QSL are more positive than those of Korean adolescents regarding general satisfaction and peer relations but are not clearly related to teacher–student relations. Since Finnish and Korean adolescents’ views on QSL partly differ from those of their Nordic and East Asian counterparts, the distinct Nordic or East Asian image of QSL could not be revealed in the study. This article proposes that QSL demands more attention in the era of ‘rankings and benchmarked educational models’, with consideration to the universality and uniqueness of institutional, sociocultural and historical factors of one’s own and others’ schooling.  相似文献   

Family Processes and Psychosocial Problems of the Young Korean Gifted     

Seokhee?ChoEmail author  Yeuhong?Yoon 《International journal for the advancement of counseling》2005,27(2):245-261

It is widely known that Korean parents have a high aspiration for providing opportunities of higher education and high expectations for their children’s academic achievement. Young Korean gifted children with ages from four to ten years did not show many psychosocial problems. However, some showed such problems as distractibility and inattentiveness, aggressiveness, helplessness, or psychiatric symptoms, when parents exert pressure, fathers are not involved in education, or parents do not discipline children’s behavior. Korean young gifted children showed high motivation for learning, when parents provide support, help, and supervision on TV watching. Based on the results, it was suggested that parents provide support for learning, rather than pressure on learning, and discipline their children’s behavior when they are young. In addition, fathers need to be more involved in their children’s learning in order to prevent psychosocial problems of the young gifted.  相似文献   

Science-specialist Student-teachers Consider Promoting Technological Design Projects: Contributions of Multi-media Case Methods   总被引：1，自引：0，他引：1

In school science, students often experience simplistic representations of knowledge-building practices in science and technology – which, in reality, are complex, unpredictable and theory-limited. While there are a great variety of reasons (many of which are beyond teachers' direct control), this occurs partly because teachers of science generally have not had such realistic experiences. While student-teachers can develop this kind of meta-scientific literacy in university-based science teacher education programmes, this depends on the extent to which activities are legitimised through close associations with authentic school contexts. In this paper, we report effects on science-specialist student-teachers' conceptions about science and technology, and corresponding priorities for school science, after interacting with a case documentary that depicted students collaborating in development and evaluation of pneumatic-controlled robotic arms. Data, including video footage of student-teachers' interactions with cases and audio recordings of interviews with them and their teacher, indicated that many student-teachers developed more naturalistic perspectives on knowledge development in science and technology and corresponding pedagogical priorities. At the same time, most also recommended an apprenticeship for students, gradually moving them from unrealistic (e.g., following a linear model for technological design) to more realistic (e.g., accommodating flexibility in design, while pointing out such limits to creativity as techno-determinism) problem solving contexts.  相似文献

Unsupervised word sense disambiguation for Korean through the acyclic weighted digraph using corpus and dictionary     

Yeohoon Yoon  Choong-Nyoung Seon  Songwook Lee  Jungyun Seo 《Information processing & management》2007

Word sense disambiguation (WSD) is meant to assign the most appropriate sense to a polysemous word according to its context. We present a method for automatic WSD using only two resources: a raw text corpus and a machine-readable dictionary (MRD). The system learns the similarity matrix between word pairs from the unlabeled corpus, and it uses the vector representations of sense definitions from MRD, which are derived based on the similarity matrix. In order to disambiguate all occurrences of polysemous words in a sentence, the system separately constructs the acyclic weighted digraph (AWD) for every occurrence of polysemous words in a sentence. The AWD is structured based on consideration of the senses of context words which occur with a target word in a sentence. After building the AWD per each polysemous word, we can search the optimal path of the AWD using the Viterbi algorithm. We assign the most appropriate sense to the target word in sentences with the sense on the optimal path in the AWD. By experiments, our system shows 76.4% accuracy for the semantically ambiguous Korean words.  相似文献

Clothing as a source of fibres within museums     

Young Hun Yoon  Peter Brimblecombe   《Journal of Cultural Heritage》2000,1(4)

This paper examines the role of visitors’ clothing as a source of fibres and dust in museums. Some idealised experiments determined the mass of fibres and dust emitted from clothing and the range of particle sizes found. In chamber studies it was possible to examine the effect of different humidity and airflow on fibre release. Image analysis was used to determine particle size from sub-micron to giant particles including clothing fibre. Clothing was a significant contributor to fibre and dust generation and at low humidity winter garments composed largely of wool was especially large. High air velocity increased particle shedding from clothing. Clean clothing typically released a third to a tenth the weight of particulate material from dirty clothing. It is possible that the fibres and dust produced indoors from visitors could be reduced by an air-shower at the entrance, but less intrusive procedures such as keeping visitors at a distance from objects may be preferable.  相似文献   

Toward a reconceptualization of information seeking research: focus on the exchange of meaning     

Kyunghye Yoon  Michael S. Nilan 《Information processing & management》1999,35(6):871

This paper reports the results of a preliminary study of interpersonal information seeking interactions between a user and a human information source. The study showed that users specify their information needs (uncertainty) largely in terms of what they know (certainty) during the interaction. The articulated certainty and uncertainty in the interaction can be classified as utterances focusing on either the topic (what the user is talking about) or comment (how that topic fits in with the user's situation or problem). We suggest that user studies in information seeking research should conceptually realign from an emphasis on user's uncertainty- and topic-based matching to the inclusion of user's certainty and comment dimensions in order to develop a more linguistically robust, multi-dimensional approach to matching for information retrieval.  相似文献
