The purpose of this study is to investigate the metatheatricality of Harris' plays marked by the device of 'play-within-a-play' - Androcles and the Lion, Arkansaw Bear, and Punch and Judy. In his metatheatrical plays Harris shows that characters perform for themselves and others. The framework that inner performance is going on within the outer frame play is formed on the stage, and this device reminds the audience in the seats that they are representing reality but that they are only in the middle of performing on the stage. Based on this point of view, this study explores fictionality of character, and play. In Androcles and the Lion, the most-performed children's play in America, the metatheatrical elements are shown in the style of commedia dell'arte, which attacks the rigidity of characters' identity in the Roman society. Another well-known children's play, Arkansaw Bear consists of realistic frame play and fantastic inner play in the mind of a girl, both of which function as a mirror each other and help to sustain aesthetic distance to death and reality on the stage. In Punch and Judy, the structure of frame play and inner puppet play reminds that what's going on in the play is just a fictional play and reflects history of children's puppet show. Harris' unique metatheatricality, the heightened awareness of his own artistic medium, offers children educational opportunity to learn about how a play is performed on the stage and contributes to convey mature theme through children's imaginary participation in the process of playmaking on the stage.

대용량 hard disk를 내장하고 있는 DTV용 PVR(Personal video recorder)에서는 단순히 수신되는 방송 stream을 녹화하고 재생하는 기능 뿐만 아니라 다른 여러 가지의 부가적인 기능들을 지원하는 것이 필요하다. 그 중의 하나가 기존의 아날로그 VCR의 사용자들에게 친숙한 fast-forward play, reverse play, pause 등과 같은 trick mode play기능을 지원하는 것이다. 그러나 MPEG video는 화면간의 상관관계를 이용하여 압축하는 방식을 채택하고 있으므로 재생하고자 하는 frame이 intra frame이 아닌 한 독립적으로 재생할 수가 없어서 trick mode play 기능을 구현하기가 용이하지 않다. 특히 reverse trick mode의 경우에는 original stream에서의 마지막 frame이 먼저 display되어야 하는데 이를 위해 하나의 GOP가 모두 decoding되어야 하므로 더욱 그 구현이 어렵다. 본 논문에서는 reverse trick mode를 구현하기 위한 여러 알고리즘을 소개하고 이에 대한 system 복잡도, 메모리 사용량 성능 등을 분석하고자 한다.

This study, based on understanding the play features of the participants, explores early children's peer-relation strategies of maintaining and altering play frame and understanding the meaning of the strategies. Free play of 5-year-old children's was observed. The child-care center was visited 1 or 2 days a week, from March to October, 2012. The data collected were based from field notes, interviews with participants, their workbooks and more. The participants used strategies such as 'refusing', 'incapacitating', 'interpreting in a way to sympathize', and 'changing the rules of play' to maintain the play, whilst 'tell-on', 'being on the same side', 'accepting 3rd party' features were used to alter play frame. Participants using these various play-frame strategies experienced life implications of 'dialectic of exclusion and selection' and 'quiver of boundary'. This study, specifying efforts of the children to maintain and alter the play frame, will provide an understanding of perception of "social exclusion" to children, which has been viewed negatively in the past. It will also benefit on-site teachers in helping them understand peer-relationship within children and provide a more in-depth intervention for peer-relationship issues.

In general, there is discontinuity phenomenon like a black screen and an irregular sound for repeated play of a finite digital stream. In this paper, for repeated play we analyze the relation between source and stream time causes this phenomenon. We obtain the time relation between video frame rate, audio frame rate, and TS packet transmission rate to eliminate this phenomenon. Using this time relation, we propose a new generation method of elementary stream (ES) and transport stream (TS) to eliminate discontinuity phenomenon. The test results of the generate ES and TS using the proposed method show that the discontinuity phenomenon can be eliminated for repeated play of a finite proposed stream.

This study examined young children's metaplay. 84 preschool subjects were videotaped as they engaged in pretend play with the same-aged peers. Dyads were identified as engaging in frequent or infrequent pretend play. Results showed that frequent pretend play dyads more engaged in request for clarification, and persuading than infrequent pretend dyads. Frequent pretend dvads were more likely to use disagreeing with reason and extending. It was concluded that developmentally useful interactions transpire outside of the pretend frame.

In this study, tubular surfaces that play an important role in technological designs in various branches are examined for the case of the base curve is not satisfying the fundamental theorem of the differential geometry. In order to give an alternative perspective to the researches on tubular surfaces, the modified orthogonal frame is used in this study. Firstly, the relationships between the Serret-Frenet frame and the modified orthogonal frame are summarized. Then the definitions of the tubular surfaces, some theorems, and results are given. Moreover, the fundamental forms, the mean curvature, and the Gaussian curvature of the tubular surface are calculated according to the modified orthogonal frame. Finally, the properties of parameter curves of the tubular surface with modified orthogonal frame are expressed and the tubular surface is drawn according to the Frenet frame and the modified orthogonal frame.

The limitation of real-time video conferencing system is that the delay of network and buffering and the transmission of user information are not efficiently performed between systems, so real - time performance is not guaranteed completely. In order to overcome this problem, the study on the extension of the network infrastructure and the jitter delay is actively carried out, but the study on the buffering delay is insufficient. In this paper, we propose a frame-rate control buffer management (FRCB) scheme to solve the problem caused by buffering delay. The FRCB is used to prevent overflow and underflow of the buffer by adopting the two-stage buffer threshold of Fast-play THreshold (FTH) and Slow-play THreshold (STH). Therefore, it showed better performance than jitter buffer even under high CPU load, and showed that it is suitable for high quality real time video conferencing.

Objective : This study is to know about the play awareness of occupational therapists with using the sensory integration approach, and is to suggest educational strategies of play as occupation and research. Methods : 124 occupational therapists completed the questionnaires including the general use of play in occupational practice and the use of play assessments with preschoolers, and factors influence on the use of play in occupational therapy for children. Results : Respondents used the play as therapy modality and performed much with based on sensory integration and development approach in individual occupational therapy room with variable play tools. It was restricted to use as objective assessment tools and methods, and had important factors that influence on the use of play in occupational therapy for children; role of occupational therapy in work setting, personal frame of reference and availability of play assessments. Conclusion : The results suggest a need for increasing the emphasis on play in entry-level curricula and continuing education, improving clinician access to valid and reliable play assessments, and completing studies designed to examine the use and efficacy of play in sensory integration therapy intervention.

This paper describes the development of low cost, miniaturized multi-function image splitter for an unmanned guard system. The essential equipments of an image splitter system consist of a video system which displays in one screen images inputted by several cameras, a frame switcher which records each image sequentially in VTR, and TBC(Time Base Control) system which prevents image flickering during image switching. Currently, the price of similar system on the market is high, system management and repair are difficult, and bulky space is required. Futhermore, since currently available frame switcher can record only 30frame/sec, if eight cameras are installed, each camera image is recorded at the low speed of 3.75frame/sec, and consequently skip some images which may be vital for legal evidence. In this research, we have solved the problem of low speed recording by recording the video screen of splitted images at 30frame/sec and zooming each image when play back.
