This study examined the friendship expectation that science-gifted and non-gifted elementary students perceived in gifted class and regular class. In 233 science-gifted elementary students and 329 non-gifted elementary students, we measured the friendship expectation that sub-domains were intimacy, ability similarity, and morality. The results of this study were as follows: First, according to the results of comparing the friendship expectations of science-gifted and non-gifted students at the regular class, there was statistically significant intergroup difference in the sub-domains of intimacy and morality, but there was no significant difference in the sub-domain of ability similarity. Second, according to the results of comparing the friendship expectations of science-gifted at the gifted class and at the regular class, there was statistically significant difference in the sub-domain of intimacy, but there was no significant difference in the sub-domains of morality and ability similarity. Based the results, the implications to understand the friendship of the science gifted elementary students were suggested in depth.

Usually, a risk can be expressed as a product of likelihood and consequence of a hazard factor. Therefore, conventional risk assessment is carried out by frequency analysis and severity analysis, in turns. However, it is well known that intuitive thinking is another excellent way of thinking of human beings. This study aimed to confirm whether there exist any difference in risk assessment results derived by two different procedures - intuitive and analytical. Thus, the present study showed 10 different illustrations to 30 undergraduate students. Their responses were organized as fuzzy membership functions, and summarized as risk assessments, and compared. The results were also verified with the help of statistical hypothesis testing, which showed no significant difference. On the contrary, however, similarity measure used in fuzzy set theory was not credible as anticipated. Many cases failed to satisfy statistical hypothesis even with similarity measure higher than 0.60 so that only a trend could be accepted. In addition, a subject showed a somewhat consistent logical discrepancy in his response, which implied the necessity of sincere analysis in fuzzy formulations.

Summarizing the differences in Chinese-Vietnamese bilingual news plays an important supporting role in the comparative analysis of news views between China and Vietnam. Aiming at cross-language problems in the analysis of the differences between Chinese and Vietnamese bilingual news, we propose a new method of summarizing the differences based on an undirected graph model. The method extracts elements to represent the sentences, and builds a bridge between different languages based on Wikipedia's multilingual concept description page. Firstly, we calculate the similarity between Chinese and Vietnamese news sentences, and filter the bilingual sentences accordingly. Then we use the filtered sentences as nodes and the similarity grade as the weight of the edge to construct an undirected graph model. Finally, combining the random walk algorithm, the weight of the node is calculated according to the weight of the edge, and sentences with highest weight can be extracted as the difference summary. The experiment results show that our proposed approach achieved the highest score of 0.1837 on the annotated test set, which outperforms the state-of-the-art summarization models.

This paper is focused on the similarity of GUI design and proposes checklists for evaluating similarity of GUI design in quantitative way and more important factors in this checklists. On the first, consideration of similarity and analysis of GUI properties are made, and from these results, the categories that affect the evaluation of similarity are extracted. The categories are consisted of 5 factors, which are concept, shape, color, relation, and multimedia. The checklists from above 5 categories are tested in 3-stage, and in this paper, 11 checklists from shape, color, and relation factor of the second stage are verified by online survey. The purpose of this survey is to find out the difference between user groups(designer, computer related, etc) and more important factors in the checklists that affect the total results of similarity. In the results of survey, the checklists have no relation with the user groups and among the checklists, external shape, composition element, and design methods have impact factors on the evaluation of similarity.

This study aims to verify the sewing technology and the expression of the virtual garment program by comparing the appearance similarity between the real and the virtual power shoulder jacket. To this end, the H and the X silhouettes of the power shoulder jacket were selected as the reference designs. After making the reference designs into real jackets by applying the human body dimensions of women in their twenties, virtual avatars and jackets were produced using CLO 3D programs. The results showed that the H-type with only expanded shoulders and less design variation had a high similarity between the reference photo and real garment, the real and virtual garment, and the reference photo and virtual garment. The power shoulder jacket of the reference picture was well reproduced in the real and virtual garments. Conversely, the X-type jacket, which is a tight fit and has many design variations, showed somewhat low similarity in the circumference items and the basic construction line. Especially in tight-fitted power shoulder jackets, the fact that shoulder angles and the essential items for pattern making cannot be reflected in reproducing virtual models was found to be a limitation in increasing the similarity of virtual clothing. Furthermore, the sewing system gap between the real and the virtual clothing exposed a difference in the appearance of virtual clothing.

In this paper we develop useful relations which estimate the difference between the solutions of nonlinear impulsive differential systems with different initial values. Then we obtain the converse h-stability theorem of Massera's type for the nonlinear impulsive systems by employing the $t_{\infty}$-similarity of the associated impulsive variational systems and relations.

The objectives of this study are to research into the traditional costume succession in south and north korea, and to compare similarity and difference of kinds, names, drawing of Jegory. Conclusions are described as follows: 1. In sort of Jegory, south and north korea have same kind of Jegory according to traditional form. But in making method, south korea have pursued various style from traditional type to modern type, north korea have maintained just simple and practical basic style. 2. South and north korea have used same or similar names for the basic part of Jegory. But north korea has made new names for constructional needs, so many differences were shown in the name of details. 3. In drawing of Jegory, north korea has hold traditional method and then tried to seek for rational, scientific technique. Also, due to the influence of south korea that advanced in modern aesthetic, drawing of Jegory in north korea were changed to similar.

A moving object detection algorithm for surveillance video is here proposed which employs background initialization based on two-stage median filtering and a background updating method based on state transition diagram. In the background initialization, the spatiotemporal similarity is measured in the subinterval. From the accumulated difference between the base frame and the other frames in a subinterval, the regions affected by moving objects are located. The median is applied over the subsequence in the subinterval in which regions share similarity. The outputs from each subinterval are filtered by a two-stage median filter. The background of every frame is updated by the suggested state transition diagram The object is detected by the difference between the current frame and the updated background. The proposed method showed good results even for busy, crowded sequences which included moving objects from the first frame.

Morphological characteristics of the Eucommia barks produced in Korea and China and of the barks of Euonymus japonicus $T_{HUMBERGI}$ in Korea and Euonymus pellucidifolia $H_{AGATA}$ in Taiwan were compared. The similarity in morphological features between Eucommiae Cortex produced in Korea and that of China suggests that both plants are of same botanical origin. However, the size of tissues and cells indicates that there is only one difference due to warm climatic environment. The similarity and difference of the barks of Euonymus japonicus produced in Korea and Euonymus pellucidifolia produced in Taiwan comfirmed that the two plants belong to the same genus and that they are different species.

In this research, we examine whether and why temporal distance influences evaluations of two different types of brand extensions: concept-based extensions, defined as extensions primarily based on the importance or relevance of brand concepts to extension products; and similarity-based extensions, defined as extensions primarily based on the amount of feature similarity at the product-category level. In Study 1, we test the hypothesis that concept-based extensions are evaluated more favorably when they are framed to launch in the distant rather than in the near future, whereas similaritybased extensions are evaluated more favorably when they are framed to launch in the near rather than in the distant future. In Study 2, we confirm that this time-dependent differential evaluation is driven by the difference in construal level between the bases of the two types of extensions - i.e., brand-concept consistency and product-category feature similarity. As such, we find that conceptbased extensions are evaluated more favorably under the abstract than concrete mindset, whereas similarity-based extensions are evaluated more favorably under the concrete than abstract mindset. In Study 3, we extend to the case for a broad brand (i.e., brands that market products across multiple categories), finding that making accessible a specific product category of a broad parent brand influences evaluations of near-future, but not distant-future, brand extensions. Combined together, our findings suggest that temporal distance influences brand extension evaluation through its effect on the importance placed on brand concepts and feature similarity. That is, consumers rely on different bases to evaluate brand extensions, depending on their perception of when the extensions take place and on under what mindset they are placed. This research makes theoretical contributions to the brand extension research by identifying one important determinant to brand extension evaluation and also uncovering its underlying dynamics. It also contributes to expanding the scope of the construal level theory by putting forth a novel interpretation of two bases of perceived fit in terms of construal level. Marketers who are about to launch and advertise brand extensions may benefit by considering temporal-distance information in determining what content to deliver about extensions in their communication efforts. Conceptual relation of a parent brand to extensions needs to be emphasized in the distant future, whereas feature similarity should be highlighted in the near future.
