  • Text mining is one of the useful tools to discover public opinion and perception regarding political issues from big data. It is very common that users of social media express their opinion with newly-coined words such as slang and emoji. However, those new words are not effectively captured by traditional text mining methods that process text data using a language dictionary. In this study, we propose effective methods to extract newly-coined words that connote the political stance and opinion of users. With various text mining techniques, I attempt to discover the context and the political meaning of the new words.

  • The aim of this study is to propose the introduction of narrative description as an improvement to describing archives, thereby enhancing the user experience of archives. To achieve this, the study identifies the specific forms and positions of narrative elements in archives and analyzes the interaction between archival description and narrative elements. It also examines cases where narrative description has been applied in digital archives to analyze their purposes and identify the various types and characteristics of narrative description for the improvement of description and considering factors that should be taken into account when implementing narrative descriptions. Theoretical research explores the concept and role of narrative and analyzes how it is manifested in describing archives. Case studies investigate the types of narrative description in digital archives and explore their roles. Narrative description emphasizes that it can facilitate implementation by establishing the narrative identity of archivists as context constructors, conducting extensive and deep research on records, and planning collaborations with experts. However, due to the lack of concrete implementation plans for narrative description in the practical archives, further research is needed to develop models of narrative description and prepare various examples of narrative applications.

  • Last year, 2008 Beijing Olympic Games have finished successfully. Over the last century the Olympic Games have received much attention from the world widely in the various point of views. In opposition to the Olympic Games, Delphic Games have attracted little attention. Moreover, There are no comprehensive monograph and research about Delphic Games in ancient and modem era. On that account, this paper will focused on the historical context of Delphic Games, review contents of it, and discuss visions to introducing and announcing the Delphic Games to the academic world.

  • Basically, objects are discriminated by transfer functions in volume rendering . However, in some cases objects cannot be discriminated only with transfer functions. In these cases, objects are pre-segmented with other methods, and visualized based on the segmentation information. In this paper we present a way of assigning per-object transparency in visualization of segmented volumes. Semi-transparent rendering is used to effectively give context information about the observed object. Per-object transparency can be used as a very effective visualization tool especially when it is difficult to adjust transfer functions to make the object semi-transparent. We present several interpretations of the meaning of per-object transparency, and corresponding variations of the algorithm. We show that efficient implementations for interactive use are possible, by presenting an implementation using general graphics hardware.

  • The purpose of this study was to investigate high school students' conceptions and conceptual types on molecular kinetic theory of gases. Data was collected by a series of semi-structured and in-depth interviews, and has been analyzed. This study showed that the students came to science classes with various prior conceptions of many disciplinary topics. Their conceptual types of their prior knowledge were distinguished as superficial terms-speaking, partial sense-making, and causal sense-making by the degrees of organization and elaboration of conceptual networks. These conceptual types had influence on the ways students understand and think of science, a stability of their conceptions, a tendency to distinguish school science from everyday science, and building a meaning of concept in contexts. It was referred that the students didn't have proper understanding on the nature of scientific knowledge and had been limited their participations as active learners. Therefore, in order for students to experience conceptual change, they must have opportunities of manifesting their own thinking, taking part in discussions, and promoting their motivations and metacognition of knowing and learning science.

  • In 1987, the Equal Employment Opportunity Law was enacted, which indicated the institutional regulation against gender-discriminatory labor practices. Until the late 1980s, women were forced to quit upon marriage. It had influenced negatively on women status in the labor market. In this paper, 1 try to examine how the institutional change affects young educated women's work behaviors. The change of the education and family effect on work will be examined. For analysis, data from 2002 Women's Work Survey is employed. The results show the followings. Among women of young generation, negative effect of education has disappeared and turned out to be positive among the never married. But, marriage and the family responsibility still influence negatively on young women's participation into the labor market. In making a decision to work, husband's attitude is more important than wife's own. But, among the single, women's own attitude toward work plays an important role. In overall, women of young generation is also influenced by the family responsibility as much as the previous generation. The negative effect of marriage and the family responsibility on women's working is stronger among the college educated women.

  • The association, word frequency and imagery have been considered as the main factors that affect the word recognition. The present study aimed to examine the imagery effect and the interaction of the association effect while controlling the frequency effect. To explain the imagery effect, we compared the two theories (dual-coding theory, context availability model). The lexical decision task using priming paradigm was administered. The duration of prime words was manipulated as 20ms, 50ms, and 450ms in experiments 1, 2, and 3, respectively. The association and imagery of prime words were manipulated as the main factors in each of the three experiments. In experiment 1, the duration of prime words (20ms) which is expected to not activate the semantic context enough to affects the word recognition was used. As a result, only imagery effect was statically significant. In experiment 2, the duration of prime word was 50ms, which we expected to activate the semantic context without perceptual awareness. The result showed both the association and imagery effects. The interaction between the two effects was also significant. In experiment 3, to activate the semantic context with perceptual awareness, the prime words were presented for 450ms. Only association effect was statically significant in this experimental condition. The results of the three experiments suggest that the influence of the imagery was at the early stages of word recognition, while the association effect appeared rather later than the imagery. These results implied that the two theories are not contrary to each other. The dual-coding theory just concerned imagery effect which affects the early stage of word recognition, and context-availability model is more for the semantic context effect which affects rather later stage of word recognition. To explain the word recognition process more completely, some integrated model need to be developed considering not only the main 3 effects but also the stages which extends along the time course of the process.

  • 3D point cloud semantic segmentation is a computer vision task that involves dividing the point cloud into different objects and regions by predicting the class label of each point. Existing 3D semantic segmentation models have some limitations in performing sufficient fusion of multi-modal features while ensuring both characteristics of 2D visual features extracted from RGB images and 3D geometric features extracted from point cloud. Therefore, in this paper, we propose MMCA-Net, a novel 3D semantic segmentation model using 2D-3D multi-modal features. The proposed model effectively fuses two heterogeneous 2D visual features and 3D geometric features by using an intermediate fusion strategy and a multi-modal cross attention-based fusion operation. Also, the proposed model extracts context-rich 3D geometric features from input point cloud consisting of irregularly distributed points by adopting PTv2 as 3D geometric encoder. In this paper, we conducted both quantitative and qualitative experiments with the benchmark dataset, ScanNetv2 in order to analyze the performance of the proposed model. In terms of the metric mIoU, the proposed model showed a 9.2% performance improvement over the PTv2 model using only 3D geometric features, and a 12.12% performance improvement over the MVPNet model using 2D-3D multi-modal features. As a result, we proved the effectiveness and usefulness of the proposed model.

  • It is not easy to understand that the drama with various aspects of political-economics and psychology in a certain popular cultural contents. People, however, does want to reconstruct the meaning of the real world and the hyper - reality, it means cross of oldness and newness, through the films. We try to analyze in religious/philosophical aspect with hybrid narrative, characters and condensed meaning in series. This try shows a good example way of understanding series which on the border line of newness and oldness.
