The effort identifying positioning information of the moving object in real time has been a issue not only in sport biomechanics but also other academic areas. In order to solve this issue, this study tried to track the movement of a pitched ball that might provide an easier prediction because of a clear focus and simple movement of the object. Machine learning has been leading the research of extracting information from continuous images such as object tracking. Though the rule-based methods in artificial intelligence prevailed for decades, it has evolved into the methods of statistical approach that finds the maximum a posterior location in the image. The development of machine learning, accompanied by the development of recording technology and computational power of computer, made it possible to extract the trajectory of pitched baseball from recorded images. We present a method of baseball tracking, based on object tracking methods in machine learning. We introduce three state-of-the-art researches regarding the object tracking and show how we can combine these researches to yield a novel engine that finds trajectory from continuous pitching images. The first research is about mean shift method which finds the mode of a supposed continuous distribution from a set of data. The second research is about the research that explains how we can find the mode and object region effectively when we are given the previous image's location of object and the region. The third is about the research of representing data into features that we can deal with. From those features, we can establish a distribution to generate a set of data for mean shift. In this paper, we combine three works to track baseball's location in the continuous image frames. From the information of locations from two sets of images, we can reconstruct the real 3-D trajectory of pitched ball. We show how this works in real pitching images.

This thesis aims to study the space concept of the constructive mode in the work space of the postmodernism artists since 1970s. According to the changing view of the world artists, they are searching for the characteristics of having the parameter of formative organization on how they are related to the constructive system which represents the work styles. First, this study searches for the theoretical approaches of the constructive system and parameters that were studied by Le Corbusier - the module concept as the meaning of order system being used for the basic formative construction Second, when it is regarded as a formative construction in making art as the'principles of organization'(the law of living form), which was defined by Suzanne Langer in the formative theory as the organized structure shown in growth structure in mu and ecological system, the principles governing the module rules were arthmetically analysed art-work space through the dynamic symmetry of Jay Hambidge. Therefore, this study shows the principles working on the parameters for new formative organization as follows: First, the module in the work space should be designed and built from the dynamic symmetry. Second, the module should satisfy the human needs that it must be acceptable, efficient, flexible, which are the necessary and sufficient condition for the dynamic symmetry. Third, the dynamic symmetry which has the principle of Reciprocity and the principle of Complement as its primary construction principle has the common properties and the reciprocity in the construction of the work space and when it has the self similarity, it segments organically the total space without damaging the continuum.

They insist that there is no more new stuff in modern art to change every circumstance rapidly. According to this situation, they recreate the works which are made with the existed idea or materials, and also transform creative concept which cites the existing functions with modern meaning. Furthermore they can look into any data everywhere from their daily routine using the internet. And this must become one of the general forms which they imitate others' works which are referred or chosen in modern art. These social complextion is called a parody and pastich is technique of the Post Modernism which is the existence of past. Using the new construction, the parody and pastich which can accomplish some better value and bring other meanings makes original recreation with the concept of copying and repeating. It keeps changing and is shaping up to be different aspect so far. Every field has a little different term using its own expression but it keeps empathizing each other a same essential meaning. Although it is like universal mode of expression, It is fact that the public cannot distinguish what is creation, imitation, or piracy. This thesis shows the concept of it and files for terms which is using like that. At last it selects some artist who worked with parody and pastich analyses and compares them and their works.

This study examined the expression mode and feature about photomontage indicated in the 21st century's Contemporary fashion. This intends to have better understanding on photomontage and to provide theoretical explanation to help a creative design development using photomontage in the future. For the research method, review over photomontage concept and its historical background was carried out with relevant literature and precedent studies. Then, analysis was followed about 258 pieces of photomontage application works featured in the four major global collections from 2001S/S to 2011F/W. Among types of photomontage expression in the Contemporary fashion, objects in the nature like animal, plant, scenery picture took up the highest frequency as motive. Other types appeared in the following order: the people-oriented type such as eminent person's figure or partial body, the ready-made image including diverse daily goods in the modern consumption society, a variety of printed stuff like cartoon, newspaper and magazine, the type of photomontage expression through borrowing the earlier famous art pieces or doing the cooperative work with artists in different fields, applications like architecture, land marks in many cities in the world, and interior, things assembled with various images, modified religious images in photomontage from Buddha or holy picture. Therefore, the modern fashion that uses photomontage could possibly feature popularity, naturalism, playfulness and creativity.

The purpose of this study was to investigate the effects of the hair style, and perceiver's generation on the perception of a high schoolgirl's image. A quasi-experimental method by questionnaire was used. The subjects were 253 high schoolgirls and their mothers living in Jinju. The data were analyzed by using frequency, factor analysis, Cronbach's alpha-reliability coefficient, three-way ANOVA, and Duncan's multiple ranges test. The high schoolgirl's image was derived in five dimensions by factor analysis: schoolgirl look, prettiness, individuality, activeness, and cuteness. In the image based on the hair length, it was assessed that the short cut and the bobbed hair styles looked more like school girls. And the short cut and long hair styles were considered as showing individuality. On the other hand, the bobbed hair style was assessed as cuter than styles of other lengths. For the bangs, the short bangs were found to more school-girl look and cuter than the long bangs. The mother group, whose ages were older than that of the other group, evaluated that the stimulative pictures had more school-girl look, individuality, prettiness, activeness and cuteness, compared to how the school girl group evaluated. It was shown that the generation gap produced different opinions about the stimulative pictures. Therefore hair style, bangs style, and difference in generations were found to be the variables affecting perception of high school girl image.

We propose a novel hydrogen-reduced p-type amorphous silicon oxide buffer layer between $TiO_2$ antireflection layer and p-type silicon window layer of silicon thin film solar cells. This new buffer layer can protect underlying the $TiO_2$ by suppressing hydrogen plasma, which could be made by excluding $H_2$ gas introduction during plasma deposition. Amorphous silicon oxide thin film solar cells with employing the new buffer layer exhibited better conversion efficiency (8.10 %) compared with the standard cell (7.88 %) without the buffer layer. This new buffer layer can be processed in the same p-chamber with in-situ mode before depositing main p-type amorphous silicon oxide window layer. Comparing with state-of-the-art buffer layer of AZO/p-nc-SiOx:H, our new buffer layer can be processed with cost-effective, much simple process based on similar device performances.

This study has been started by the trendy analysis of parody in post-modern dance. Creative parody is not an imitative work but provides new originality of a work of art and serves as the criticism. Since the 1960s the trend and characteristics of using parody in post-modern dance can be classified into five concepts which are the cultural diversity, the autonomous thinking ability, the aesthetic perception, the use of the mass media and the cultural relations of the critical process. In conclusion, the parody elements in post-modern dance are due to the cultural diversity, and the experimental values which are divided into the beauty of content and mode has been acted as the important factors to achieve the parody elements to new dimension.

A rational and logical sense of design often found in modernism(including minimalism) sometime deal with the criticism that such characteristics which derived from those of modernism, lack emotion31 qualities(arises from human feelings). It consequently took them to adopt traditional designs in the past, creating such conditions that constantly escapes from‘present’ one and back to the‘new’. This mode develops a trend in current interior design which decorative elements such as art work: traditional arts, folk crafts, flowers and green are much evident. Thus, using many decorative elements of the past(what was once banned since modernism), brings up the interesting point of view that needs to be discussed a new decorative trend if today's interior design. It will approach by comparing significances of past decorative expressions with present through which investigation, will show a better understanding of recent characteristics in interior designing, a.k.a, a current trend since minimalism, embracing important qualities of culture, ecology and people - against today's less-inspired, standardizing spaces.
