The ray-shooting problem is to find the first intersection point on the surface of given geometric objects where a ray moving along a straight line hits. Since rays are usually given in the form of queries, this problem is typically solved as follows. First, a data structure for a collection of objects is constructed as preprocessing. Then, the answer for each query ray is quickly computed using the data structure. In this paper, we consider the ray-shooting problem about the set of vertical line segments on the x-axis. We present a new data structure called a convex layer tree for n vertical line segments given by input. This is a tree structure consisting of layers of convex hulls of vertical line segments. It can be constructed in O(n log n) time and O(n) space and is easy to implement. We also present an algorithm to solve each query in O(log n) time using this data structure.

Methods of delivering products to consumers do not act as less important factor than creative activities to create new product designs. Mobilizing various psychological elements based on human instinct and desire, fashion industry presents a product as an object of envy, gaining viewers' attention. Here, the viewer does not simply take the product as an object to view, but also imagine transformation it will bring. The study of the cause and effects of the interaction, which is found in the relationship between "the viewer" and "what is viewed" is an important factor that needs to be identified in the phase of creation as well as in the aspect of delivery. The relationship between the perceiver and what is perceived features in designs, product advertisements, related articles, and fashion shows in modern fashion, serving as a medium that enables the humans, who must inevitably exist between the two poles such as mind and body, the subject and the object, the ego and non-ego, and the reality and an ideal, to communicate between the poles. Humans cannot do arbitrary acts or make arbitrary selections only as they access to foreign things through instinct, desire, or experienced perception, and they are sometimes positioned passive by things. In the background, as there are human dual characteristics in which they are expressed as the ego and another ego who exists inside of the ego, they not only view an object, but also become an object to be viewed. Many products in modern fashion, as the objects of reciprocal transposition, grow giving illusions to humans. Having a desire for such objects is human's instinct and normal act to keep the life balanced between the reality and an ideal, which is based on the activation of reality function. Furthermore, freely acting rather than ignoring or overcoming the desire may be the act of retrieving one's ownership to the ego.

Body painting according to physical types is a method to express the body as it exists in nature or as an active element of nature. There is a need to research physical formation that applies the trend of contemporary naturalism to the types of nature art by emphasizing the artistic value of body painting with natural environmental overtones. Importantly, body painting according to physical types attempts an intact reproduction of natural objects and the reflection of the beauty of natural objects in body painting. Thus, the purpose of this study was to analyze body painting according to physical types based on the types of nature art. The methodology of the study included theoretical and empirical review. Theoretical review examined the characteristics of physical formation in nature art and relevant nature art works and body painting of physical types through previous research and literature. The empirical review applied analyses to works extracted from web sites of body painting. The study included physical type cases extracted from body painting works from 2005 to 2015 in foreign web sites(www.ilovebodyart.com and www.angel cakebodyart.com). Body painting works were based on the characteristics of physical types. As a result, the body painting of physical types based on nature art is as follows. First, organic continuity with nature art through the artists'thoughts and beliefs. Second, the specificity of place that respects the natural phenomenon itself. Third, the creative diversity of formative shapes for the body. Fourth, the social implications of body painting with human empathy. Fifth, immediacy to embody the artistic will of the artist. Finally, the application of physical types according to affinity with nature, as well as an independent artistic entity.

In order to evaluate the performance of incremental update algorithms, we perform experimental tests on the time of updating view objects. In this paper, the incremental update algorithms are evaluated on two kinds of materialized methods : materialization by value-copy and materialization by preserving object identifiers (OIDs). The result of performance evaluation shows that there is little difference in the updating time of view objects between two materialization methods. The evaluation of query processing on spatial views shows that materialization by value-copy is much better than materialization by preserving OIDs. As the results of overall performance evaluation, it is more desirable to use the incremental update method based on materialization by value-copy than the incremental update method based on materialization by preserving OIDs.

This article was intended as fundamental materials to recognize the current status of furniture hard ware in Korean market and to fix the identity of Korean furniture, by investigating and comparing the furniture hard ware used in the Joseon era and in modern times by type, function, shape and material. The analysis of furniture hard ware of the Joseon era and modern times from the view of functional aspects was oriented to the hard ware necessary to open and close the door & drawer on one side, and to that being attached to the main body of furniture not to scratch the wood by another wood on the other side, and from this the following conclusion was drawn. First of all, "Gwangdoojung" - a kind of spike- and metal decoration on the edge of the furniture disappeared, while the function-oriented hard wares have been diversified in modern times, from the perspective of the change of kinds. Second, the functional aspect of the furniture hard ware was emphasized in modern times than the Joseon era. In other words, the hard wares of the Joseon era came into view due to their strong appeal to decoration, whereas those of modern times were mostly hidden or moderated, keeping the function substantially. Third, the hard wares from the Joseon era were shown in concrete and detailed shape motivated by natural objects and furthermore even gloriously, but the modern hard wares are simple & basic geometry, from a formative point of view. Fourth, the material aspects present that the Joseon era's hard ware was mainly cast iron, whereas that of modern times shows the diversification from metal to even plastic. Finally, the recent trend in naming of the hard wares is the words of foreign origin. This resulted from that the foreign names of hard wares are valid also after import process in Korean market, so the domestic development of hard ware as the essential factor for the furniture design is urgently necessary to establish the identity of Korean modern furniture.

It is challenging to detect foreground objects when background includes an illumination variation, shadow or structural variation due to its motion. Basically pixel-based background models including codebook-based modeling suffer from statistical randomness of each pixel. This paper proposes an algorithm that incorporates Markov random field model into pixel-based background modeling to achieve more accurate foreground detection. Under the assumptions the distance between the pixel on the input imaging and the corresponding background model and the difference between the scene estimates of the spatio-temporally neighboring pixels are exponentially distributed, a recursive approach for estimating the MRF regularizing parameters is proposed. The proposed method alternates between estimating the parameters with the intermediate foreground detection and estimating the foreground detection with the estimated parameters, after computing it with random initial parameters. Extensive experiment is conducted with several videos recorded both indoors and outdoors to compare the proposed method with the standard codebook-based algorithm.

The purpose of this article is to represent the types of advertising in the modern Russian language as 'Play of Words' (игра слов). The causal reason for this phenomenon is studied from the result of certain characteristics of advertising. The definition and characteristics of the language of the advertisement are analyzed in achieving the goal, as these factors reveal how language is used to maximize the effectiveness of the advertising. Academic research is needed in the collaborative fields of linguistics, psychology, economics, sociology, marketing, literature, art, and music. Modern advertisement is mixed with semiotic objects that consist of display, sound, and texts. While this study is not complete, the acknowledgement of the phenomenon 'Play of Words' between the creators of advertising and the consumer is undeniable. On one hand, advertising is recognized by linguists as the main factor that destroys the literary language. It represents the distortion of a standard language norm, as opposed to formal linguistic means used in advertising. In this research, we pay attention to the frequent use of foreign language borrowings and incorrect representation of foreign words, slang and jargon, that occur in misspelled usage of literary norms. The features that are revealed in this article are helpful to understand the purpose of advertising.
