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.

애니메이션을 처음 만드는 초보 애니메이터들에게 어려운 것 중 한 가지는 바로 타이밍을 잡는 것이다. 애니메이션에서 타이밍은 캐릭터에게 생동감을 가지게 하며, 캐릭터의 감정을 전달하는 역할을 한다. 애니메이션에서 어떠한 상황이나 분위기에 맞는 타이밍이 주어져야만 그 대상의 무게와 크기를 반영할 수 있기 때문에 타이밍을 공식화 하는 것은 불가능한 일이며, 자신만의 타이밍을 잡는 것이 중요하다. 이러한 타이밍과 밀접한 관계를 가지게 되는 것이 애니메이션 사운드인데 어떠한 사운드를 정하는지에 따라서 애니메이션의 분위기가 결정되며 정확한 화성코드와 음악만으로 극적인 연출을 할 수 있다. Mickey Mousing 이란 움직이는 동작과 음악을 일치시키는 기법을 말하며, 본 논문은 Mickey Mousing 기법을 중심으로 애니메이션 사운드를 이용하여 사운드의 리듬과 템포에 따른 애니메이션 캐릭터의 움직임과 타이밍을 잡는 방법을 '톰과 제리', '크리스마스의 악몽'을 통하여 제시하고자 한다.

The purpose of this study was to identify the preferred materials and design characteristics of nursing home clothes in order to collect the basic data necessary for the elderly nursing home clothes. It was to utilize the elderly nursing home clothes considering elderly body shape, hand function, illness. This study was conducted by questionnaire method and SPSS ver. 20.0 program was used. The preference for nursing home clothes material was high for cotton, and it was found that they prefer soft, stretch material, warm feeling material, and lightweight material. In the hygienic aspect, they favored sweat-absorbent materials, and preferred laundry- care-resistant materials with poor wrinkles and dirtiness. The nursing home clothes preferred a two piece form consisting of a round neckline, two pockets on both sides, a waistband of rubber band, long lengths, and a waistline pants. The most important function in the nursing home clothes was recognized as wearing comfort. Aesthetics, symbolism, color and print pattern were recognized as not important functions. Therefore, it is necessary to focus on the functional part such as wearing comfort in the design of the nursing home clothes. The material is also hygienic and comfortable to wear. In the case of the elderly, it is necessary to provide convenience for the wear of clothes through the development of stretchable material and detachment device since the movement range of muscles, arms, and legs is reduced. Based on this study, we will utilize it for the development of nursing home suit considering the characteristics of elderly person in the elderly society. It is to develop functional materials for the elderly in need of nursing home, to develop the pattern considering the elderly body shape, and to develop the desorption device considering the movement of the hand.

Objectives: This study was conducted to develop the Mobility to Participation Assessment Scale for Stroke (MPASS) and assess its content validity, internal consistency, inter-rater and intra-rater reliability, and convergent validity in people with stroke living in the community. Methods: The MPASS was developed using published data on mobility-related activity and participation timing in elderly individuals, and then reviewed by community physical therapists. Content validity was established by reaching a consensus of experienced physical therapists in a focus group. The MPASS was scored for 32 participants with stroke (mean age 61.75±4.92 years) by 3 individual testers. Reliability was examined using the intraclass correlation coefficient (ICC), internal consistency using the Cronbach alpha coefficient (α), and convergent validity using the Pearson correlation coefficient (r) to compare the MPASS to the Modified Rivermead Mobility Index as a referent test of mobility. Results: The MPASS consists of 8 items, and its scoring system provides information on the ability of people with stroke to reach a movement level enabling them to live in society, including interactions with other people and safe living in the community. The interrater and intra-rater reliability were excellent (ICC, 0.948; 95% confidence interval [CI], 0.893 to 0.982 and ICC, 0.967; 95% CI, 0.933 to 0.989, respectively). Internal consistency was good (α=0.877). The convergent validity was moderate (r=0.646; p<0.001). Conclusions: The newly developed MPASS showed acceptable construct validity and high reliability. The MPASS is suitable for use in people with stroke, especially those who have been discharged and live in the community with the ability to initiate sitting.

Non-representation creates difference and change that can be used as a creative design method that satisfies contradictory requirements for similarity and differentiation. This study drew upon the characteristics of the concept of non-representation expressed in contemporary art and architecture, in which Gilles Deleuze's philosophical thinking was reflected, and analyzed the non-representation depicted in contemporary fashion. The non-representation expressed in contemporary art and architecture is as follows. Non-representation of delaying becoming focuses on reverting to preexisting objects and redefining traditional meaning, thereby delaying the representation of latent meaning. Non-representation of non-becoming removes existing values and typical forms and expresses amorphousness. Non-representation of becoming by repetition or reiteration realizes the difference caused by the passage of time by repeating or overlapping shapes. Non-representation of becoming expresses the transformation of space by flowing through time rather than by actual movement. Non-representation in contemporary fashion shows the following expression characteristics. First, the non-representation of deferring becoming deconstructs the traditional values and forms of clothing and expresses designs by displacement or juxtaposition. Second, the non-representation of non-becoming is expressed concepts unrelated to the body and focus upon amorphous objects that do not become concretized forms. Third, generative non-representation by repetition and overlap expresses the possibility of change by overlapping clothing items or details expressed by repeating segmented objects. Fourth, generative non-representation by movement reproduces the meaning of space and time by moving the shape of the clothing or visually changing the surface of the material of clothing. As a result of the study, the non-representation shown in contemporary fashion aims for versatility to conform to social changes. This study provides new insight into the fashion design method by increasing the understanding of the cocnept of non-representation and showing its potential.

The present study investigates the effects of syllable structure and prosodic prominence on the patterns of tonal alignment and scaling of the phrase-initial rise in Seoul Korean. Two syllable structures (Onset (/#CVC.../ as in minsa) vs. No-onset (/#VC.../ as in insa)) and two prominence conditions (Focus vs. Neutral) were considered. Results showed that the alignment of the L and the H tones in the phrase-initial rise was affected by syllable structure but not by prominence. The time of L was before the vowel onset of the first syllable in the Onset condition (i.e., within the onset consonant) and it was after the vowel onset in the No-onset condition. The difference was attributable to the fact that the initial L was anchored at a fixed distance from the phrase boundary, which was about 30ms after the onset of the syllable in both cases. The time of H was also consistently observed about 20ms after the second vowel onset (i.e., /a/ in minsa/insa). Moreover, the rise time (the duration from the L to the H tones) was longer as the local syllable duration became longer due to different syllable structure and prominence conditions. Taken together, the results provide a support for the segmental anchoring hypothesis, which claims that both the beginning and the end of F0 movement are consistently aligned with segmental 'anchor' points with relatively high stability (Ladd et al., 1999). Results also showed that the scaling of the early rise was slightly influenced by syllable structure but not by prominence. The differences between the results of the current study and a previous study (Cho, 2011) are further discussed.

For the purpose of this study is the re-searcher investigated the concept and background of kitsch and the character of Kitsch in the paintings with focus on the Surrealism and Pop Art. In this study it was focused that how the shapes and materials was expressed in the modern fashion. Surrealism in paintings is lead thoughts and art movement to humanism of be-having man and pursuit of mental sub-stance of human beings expressing un-conscious word and transforming image in new way by the methods Automatism and Depaysements. Pop Art in paintings is used to objects common and cheap in the popular con-sumer's society. That is to say Pop Art sublimated con-sumptional culture of mass as art. And this phenomenon is appeared in the modern fashion which have influencedon the shapes and materials in design. Kitsch's character was researched in terms of shapes materials in the modern fashion with focus on the Surrealism and Pop Art and their aspect are summarized as follows: 1. In he aspect of shapes it appears that the shapes in the modern fashion is that of play through the method distor-tion or modification of dress. It was un-derstood that the cause of the dreaming and fantasy in the childhood. In the aspect of materials it apepears that the materials in the modern fashion is that of exagerated-decoration through using of object which is various asses-sories flower doll etc. 2. In the aspect of shapes it appears that the shapes in the modern fashion is that of disharmoney disorder and unsuit-ableness. The major cause of that is be-cause of Antistandard fashion I the aspect of materials it appears that the materials in the modern fashion is that of sarcasm pleasantness. It was reviwed that the major cause of the wit or humor comes from the image of the masses makes use of such as plastic fun-ny picture can coin etc.
