This study aims to find out differences between designer's design guidelines and user's actual behavior about play facilities of children playground in multifamily housing site by using the method of Post-Occupancy Evaluation. Korea National Housing Cooperation developed the 18 play facilities and constructed them into children' playground of Bun-dong and Junggae-dong housing site in Seoul. The results are as follows: First, user's behaviors which differed from designer's guidelines were influenced by mechanical and technical problems rather than design. Second, users adjusted their brahvior to play facilities which have a little operational problems. Third. users tried to make dangrous activity instead of designer's guidelines based on the safety. It infers that users want to make creative activities from play facilities. Fourth. designers should have developed play facilities for infants and youth. Fifth. users liked to play more complicated play facilities rather than single facility.

DVRs are the most common recording and displaying devices used for surveillance. Video compression plays a key role in DVRs for saving storage; the video compression standard, H.264/AVC, has recently become the dominant choice for DVRs. DVRs require various display modes, such as fast-forward, backward play, and pause; these are called trick modes. The implementation of precise trick mode play requires a very high decoding capability or a very intelligent scheme in order to handle the high computation complexity. The complexity is increased in many surveillance applications where more than one camera is used to monitor multiple spots or to monitor the same area using various angles. An implementation of a trick mode play and a frame buffer management scheme for the hardware-based H.264/AVC codec for multi-channel is presented in this paper. The experimental results show that exact trick mode play is possible using a standard H.264/AVC video codec with keyframe encoding feature at the expense of bitstream size increase.

In this paper we describe a development of a multi user game using 3D graphics and multicasting. First, we represent a virtual reality world by 3D graphics technology. Next, we use computer communication technology for the purpose of interaction among multi users. As a result, multi users share 3D graphics objects and play games. The goal of this paper is a development of a system that enables multi users to play games sharing a virtual world represented by 3D graphics. We use the OpenInventor library and C++ language for 3D graphics scene representation, and IP multicasting protocols for computer communication. The system allows to use Polhemus Fastrak 3D input device that recognizes the 3D position and 3D orientation. As an example we present a game that demonstrates the effect of piano concert by multi piano players who are distributed in a computer network.

The aim of this paper is to examine satisfaction of residents and preference on the outdoor space's design by multi-family housing complex scale. So we divide outdoor space into space for green land, space for physical training and play, space for walking and space for rest and landscape facilities. The major findings of this analysis are follows : Multi-family housing complex scale is the bigger, it is recognized by same ratio on specific outdoor space in housing complex that are space for green land, space for physical training and play, space for rest and landscape facilities. And space for physical training and play is found commonly into the poorest space in housing complex. Evaluation for resident's perception on outdoor space by multifamily housing complex scale shows that housing complex scale is the bigger, resident's satisfaction is the lower. That means that housing complex of large scale can't satisfy the diverse resident's demand.

The purpose of this study is in analyzing factors related to a teacher's nursery efficacy. In order to achieve its purpose, a study includes investigation about levels of 748 teachers' interest and knowledge in a child nursery from multi-cultural families, teachers' efforts for understanding the children from multi-cultural families, availability of experience with a child care from multi-cultural families, a teacher's multi-cultural nursery efficacy and general nursery efficacy. As a result of investigation, a study found out that 4 factors (interest, knowledge, efforts, and experience) are related to nursery efficacy and the fact that a teacher's general nursery efficacy is highly associated with multi-cultural nursery efficacy. For this result, providing information about a child care from multi-cultural families and supporting general nursery efficacy play a critical role in supporting teachers' competency about a child care from multi-cultural families.

The communication in a play has a dual structure, which is composed of the communications within a play and in a theatre space. This research focuses on the scene design that creates the background or the theme of a play and communicates theme of a play to the audience. A scene design of a theatre has meta-linguistic aspects, which is the image or mood as the theme of a play. The scene design is composed of various design elements of space and objects as the properties of a play. Design elements and the objects are the design languages in various form; plane, three-dimensional, multi-dimensional form. These design languages have the significant meanings as signs like human language. The play works chooses the rhetorical expression to arouse the audience's sympathy. The scene design is completed with rhetorical expression for communication in theatre too. This research defines the category of meanings that design elements of scene design can create and the rhetorical expression of the scene design language. King Lear directed by Robert G. Anderson was analyzed with the category of design elements as a sign and the pattern of the rhetorical expression. The scene design for a play is completed effectively by the rhetorical expression of design elements as the design language for the communication with the audience in theatre.

Landscape space can and should play as a multi-functional agent : healing contaminated soil, reducing natural hazards, supporting living things, making comfortable environment for human, and appealing to human aesthetics, etc. This article aims to show the possibility and role of landscape space as such agent. In landscape design for National Marine Biology Resource Institute, distributed rain water treatment system and rain gardens are introduced to replace a mono-functioning large detention pond which was suggested by disaster impact assesment. Phytoremediation and vegetation filtering system with muti-cell wetlands are also adapted to heal the contaminated soil. This kind of landscape as a 'living machine' which can play as an operational control utility of multi-environment and thus can be combined effectively into green infrastructure is important for post-industrial city, especially in an era of climate change.

Remarkable advances in nanomaterials and nanotechnology have led researchers in various fields. The scale effects imparted by nanomaterials are associated with unexpected macroscale phenomena and properties that find many applications. However, multi-functionalization may be accompanied by physical and commercial limitations. Therefore, research must proceed in several different directions. Here, we define multi-functionalization and the electrical applications thereof in terms of increasing performance, addition of new and valuable properties, and multi-physics in play. We deal with sensors, actuators, energy harvesters, and solar cells and explore research that seeks to increase sensitivity, append "stretchability", and facilitate untethered communication. Furthermore, we analyze research trends in materials use and manufacturing, and highlight useful fabrication methods. With the aim of predicting future research trends, our review presents a roadmap that will aid research on sensing and multi-functional applications.

Objective: The purpose of this study was to investigate the moderate effect of the physical environmental-level between infant teachers' positive play beliefs and teacher-infant interaction. Methods: The subjects of this study were 483 teachers in charge of one-year-old and two-year-old infants in child care centers located in metropolitan areas. The data were collected by asking the teachers to respond to a questionnaire and the data collected were analyzed through correlation and hierarchical multi- regression analysis. Results: First, the positive play beliefs of the infant teacher, the physical environment level, and the teacher-infant interaction showed significant proportional correlations. Second, the physical environment level moderated the influence of the teacher's positive play beliefs on teacher-infant interaction. In particular, results showed that functional interior space configuration, outdoor playground composition and facilities among the sub-variables of the physical environment level had a moderating effect. Conclusion/Implications: The results of this study show that teachers with positive play beliefs have positive teacher-infant interaction when there is sufficient space available for infants and teachers. This indicates that the human and physical environments of child care centers can promote teacher-child interaction.
