Contemporary viewers familiar with the digital space show their desire for self-expression and use voice, text and gestures as tools for expression. The purpose of this study is to create interactive art that expresses the narrative uttered by the viewer in the form of a collage using the viewer's figure, and reproduces and expands the story by the viewer's movement. The proposed interactive art visualizes audio and video information acquired from the viewer in a text collage, and uses gesture information and a natural user interface to easily and conveniently interact in real time and express personalized emotions. The three pieces of information obtained from the viewer are connected to each other to express the viewer's current temporary emotions. The rigid narrative of the text has some degree of freedom through the viewer's portrait images and gestures, and at the same time produces and expands the structure of the story close to reality. The artwork space created in this way is an experience space where the viewer's narrative is reflected, updated, and created in real time, and it is a reflection of oneself. It also induces active appreciation through the active intervention and action of the viewer.

Nominalization is one of the grammatical metaphors, and it is the representation of verbal meaning through noun equivalent phrases. In mathematical word problems, texts using nominalization have both the advantage of clarifying the object to be noted in the mathematization stage, and the disadvantage of complicating sentence structure, making it difficult to understand the sentences and hindering the experience of the full steps in mathematical modelling. The purpose of this study is to analyze word problems in the textbooks from the perspective of nominalization, a linguistic element, and to derive implications in relation to students' difficulties during solving the word problems. To this end, the types of nominalization of 341 word problems from the content domain of 'Numbers and Operations' of elementary math textbooks according to the 2015 revised national curriculum were analyzed in four aspects: grade-band group, main class and unit assessment, specialized class, and mathematical expression required word problems. Based on the analysis results, didactical implications related to the linguistic expression of the mathematical word problems were derived.

The aim of this research was to verify the mediating effects of ambivalence over emotional expressiveness and distress tolerance on the relationship between harm avoidance and depression. A total of 403 university students completed TCI-RS(Temperament and Character Inventory-Revised Short version), AEQ-K(Ambivalence over Emotional Expressiveness Questionnaire-Korean), DTS (Distress Tolerance Scale) and CES-D(The Center for Epidemiologic Studies Depression Scale). The results revealed that harm avoidance and ambivalence over emotional expressiveness were positively related with depression, and negatively related with distress tolerance. In addition, the relationship of harm avoidance and depression was successively mediated by ambivalence over emotional expressiveness and distress tolerance. That is, the motivation of emotional expression conflict may have an effect on depression and the distress tolerance would play an important role in therapeutic intervention of depression.

In elementary school mathematics, the addition and subtraction of fractions are difficult for students to understand but very important concepts. This study aims to examine the teaching methods and visual aids utilized in the context of common denominator fraction addition and subtraction. The analysis focuses on evaluating the lesson flow and the utilization of visual representations in one national textbook and ten certified textbooks aligned with the current 2015 revised curriculum. The results show that each textbook is composed of chapter sequences and topics that reflect the curriculum faithfully, with each textbook considering its own order and content. Additionally, each textbook uses a different variety and number of visual representations, presumably intended to aid in learning the operations of fractions through the consistency or diversity of the visual representations. Identifying the characteristics of each textbook can lead to more effective instruction in fraction operations.

People have competing desires. Hence, people not only chase others' choices due to the need for assimilation but also avoid others' choices due to the need for differentiation. This study attempts to uncover under which conditions consumers assimilate with or differentiate from others' choices. Specifically, the study extends previous research about the effect of others' choices by focusing on the effect of a choice situation (purchase vs. usage) based on the conformity theory and the uniqueness theory. It was found that purchase (vs. usage) situation makes people more conform to others in case of identity-irrelevant product (e.g., USB memory stick). Also, the effect of the choice situation was moderated by the perceived identity-relevance level in case of identity-relevant product (e.g., jeans).

In this paper, we propose a fast GPU-based method for representing pore flow, absorption, emission, and diffusion effects represented by cloth-liquid interactions using smoothed particle hydrodynamics (SPH), a particle-based fluid solver: 1) a unified framework for GPU-based representation of various physical effects represented by cloth-liquid interactions; 2) a method for efficiently calculating the saturation of a node based on SPH and transferring it to the surrounding porous particles; 3) a method for improving the stability based on Darcy's law to reliably calculate the direction of fluid absorption and release; 4) a method for controlling the amount of fluid absorbed by the porous particles according to the direction of flow; and finally, 5) a method for releasing the SPH particles without exceeding their maximum mass. The main advantage of the proposed method is that all computations are computed and run on the GPU, allowing us to quickly model porous materials, porous flows, absorption, reflection, diffusion, etc. represented by the interaction of cloth and fluid.

In this paper, we present a particle-grid blending framework based on a geometric approach to efficiently represent opaque ice spheres with air bubbles. The water temperature is diffused through the grid and the air bubbles represented inside the ice through the particles. To solve the problem of previous methods that generate noisy dissolved air fields, we use levelsets to lighten the algorithm, i.e., the number of active particles and the initial amount of dissolved oxygen can be used to efficiently control the termination conditions of heat diffusion. We also extend the previous dissolved air field method, which only computes near air bubbles, to transparent regions to represent realistic ice spheres, and introduce a levelset-based approach to accurately compute the orientation of particles. As a result, the method presented in this paper is about three times faster than the existing methods and shows visually improved visualization of opaque ice spheres, which can be used in the field of representing physical virtual ice forms.

Objectives : Objectives of this study was to explore the relationships between anger, alexithymia and premenstrual syndrome(PMS). Methods The subjects included 125 women with PMS and 58 women with non-PMS assessed by Daily record of Severity of Problems(DRSP) and Shortened Premestrual Assessment Form(SPAE). Anger level was assessed by anger expression scale. The level of alexithymia was assessed by Toronto alexithymia scale. We compared the scores of anger, alexithymia between PMS group and no-PMS group. Results : The mean scores of anger in(p=0.04), anger total(p=0.01) were significantly higher in women with PMS compared to control subjects. and the mean scores of alexithymia(p=0.04) were also significantly higher in women with PMS compared to control subjects. Conclusions : This study showed that the level of anger and alexithymia could be higher in women with PMS compared to control subjects, and that symptoms of PMS could be associated with anger and alexithymia. therefore, It would be better to consider the level of anger and alexithymia in treating and evaluating women with PMS.
