In Korean apartment housing, balcony is semi-outdoor space for storage and drying laundry. Recently, this semi-outdoor balcony space has been merged into indoor living space with the legal permission of balcony extension. It results in disappearance of the original function of balcony in apartment housing. This study attempts to propose better utilization of balcony extension by analyzing how balcony has been extended and used, and what residents' needs are. This study asks 400 housewives living in apartment housing in Jangyu new urban area, Kyungnam. Findings are : 1) Balcony extensions are carried out in a living room, a large bedroom and a small bedroom. Most extensions are made for enlarging adjacent indoor living space; 2) Original balcony that is not extended is used for drying laundry, resting, flower pot, storing, and kid's playing; 3) The residents recognize that problems of balcony extension are the decreased heating efficiency, the reduced soundproofing effect, the loss of spare housework space, and the disappearance of buffer between indoor and outdoor space; 4) Many residents want to extend their balcony space of a small bedroom and a large bedroom and to keep the balcony space of a kitchen-dining room and a master bedroom as they are.

This study aimed to analyze the types and characteristics of space forms according to the composition of the stage and auditorium space along with the expression trends in the space of performing arts centers through the cases of modern performing arts centers in America. Today since the purposes of performance are multiple, a variety of stage types are applied to each performing arts center. They use various spaces and performances of multiple purposes by moving and transforming the stage and auditorium according to the kinds of performance as a variation of the arena stage. In today's performing arts centers, the sizes of the stage and auditorium can vary widely, and the performances of many different genres are put to multiple purposes. There appear complex performing arts centers that can plan performing spaces of diverse sizes and forms to fit the functions of a performance in a large building. Since they put on performances in a large space according to the characteristics of the kind of performance, the intentions and goals of the performance are well delivered to the audience.

This paper analyzes the continuous Galerkin method for the space-time discretization of wave equation. The method of space-time finite elements enables the simple solution than the usual finite element analysis with discretization in space only. We present a discretization technique in which finite element approximations are used in time and space simultaneously for a relatively large time period called a time slab. The weighted residual process is used to formulate a finite element method for a space-time domain. Instability is caused by a too large time step in successive time steps. A stability problem is described and some investigations for chosen types of rectangular space-time finite elements are carried out. Some numerical examples prove the efficiency of the described method under determined limitations.

The underground space of the Banwoldang in Daegu is the private enterprise historical development project that Daegu City & The forth construction company of the Samsung, Kolon, Daewoo, Hwasung promote, and take a role as the underground bridgehead that links east and west of the Daegu as the lunction of the 2 subway line. Accordingly, the underground space of the Banwoldang in Daegu have a import significance in that not only the alternative of the solution about the simple commercial formation or the limited ground but also compose the important axis of the city develoment. But, When I see the variety of problems, especially see the negative import in Daegu, the solution of the problems is the large underlying cause that revitalize the city. Consequently, in the study I would like to analyze the characteristics of the large underground space and the directivity of the interior design, to assistant for the develement plan of the more safe, comfort underground space.

The lack of short baselines, referred to as the short-spacing problem (SSP), is a well-known limitation of the performance of radio interferometers, causing a reduction of the flux detected from source structure on large angular scales. The very large number of antennas operated in the Atacama Large Millimeter/sub-millimeter Array (ALMA) generates situations for which the impact of the SSP takes a complex form, not simply measurable by a single number, such as the maximal recoverable scale. In particular, extended antenna configurations, complemented by a small group of closeby antennas at the centre of the array, may result in a double-humped baseline distribution with a significant gap between the two groups. In such cases one should adopt as the effective maximal recoverable scale the one associated with the extended array and use only the central array to recover missing flux, as one would do with single dish or ACA (Atacama Compact Array) observations. The impact of the missing baselines can be very important and may easily be underestimated, or even overlooked. The present study uses ALMA archival data of the ²⁹SiO(8-7) line emission of the AGB star W Hydrae for a demonstration. A critical discussion of the reliability of the observations away from the star is presented together with comments of a broader scope. Properties of the circumstellar envelope of W Hya within ~15 au from the star, many of which are not mentioned in the published literature, are briefly described and compared with R Doradus, an AGB star having properties very similar to W Hya.

Large aperture antennas with long focal lengths in space have important application for telecommunications, Earth observation and science missions. This paper aims to understand the dynamics of deployment of large mesh antennas and to provide a multibody model for determining the driving forces for the design of reflectors and booms. The modular deployable reflector and boom are designed based on the deployment unit cell. A multibody dynamic model is formulated with Kane's equation and simulated using the pseudo upper triangular decomposition (PUTD) method for solving the constrained problem. Based on the multibody dynamic model, the kinetics of the deployment, the motor driving forces, and the structural dynamic deformation are investigated.

Lately construction companies are differentiating the outdoor spaces of apartment complexes to satisfy the needs of residents by providing underground parking area and variety of outdoor community spaces. Building walking networks through residential unit area, the major passage area and the entrance area of the complexes is very important factor to increase the use of the outdoor environment in the complexes. The purpose of this study is to evaluate the characteristics and the elements for the planning of exterior pedestrian spaces carefully through the analysis of current large-scale apartment complexes. In this study, the utilization of space, the connectivity to other spaces and the application of Universal design were evaluated through site visits in 5 large-scale apartment complexes. As a result, the utilization of space is well applied in the most of complexes especially in residential unit area. The connectivity to other spaces has low application compared to the others. Universal design is also well applied except sub criteria for the blind in most of complexes. This study will be able to help in providing better exterior pedestrian environment for residents in apartment complexes.
