Recently, the increase of single households are remarkable in Korean society due to various social and economic reasons such as aging and changes in values, and it is expected to bring many changes to social and economic structures and residential spaces. Increase of single households is a result of complex economic, cultural and social factors. It is because as the individual's financial independence increases due to elevated income and education level, the age of marriage is going up and the individualism, which values the individual's value rather than custom, is spreading. It is expected to accelerate further in connection with the changes in structure of population, such as a low birth rate and aging. As the number of single households is increasing, the development and marketing for single household products are actively growing. With the increase in consumption demand and need of growing single households, the multi-functional system furniture that can be efficiently and conveniently used in small spaces are needed, but the furniture manufactured in Korean companies are designed for regular housing and is not suitable for single households. Therefore, the aim of this study is to develop multi-functional system furniture can be freely used in the housing structure of single household and small spaces.

The purpose of this study is to clarify the actual condition of the daily living activities of the elderly with dementia in nursing homes. The thorough investigation and observation works were made from the view points of daily living behaviors and behavioral places of the recuperating elderly with dementia in nursing homes. This article discusses about the basic characteristics of the elderly and the actual condition of the daily living activities of the elderly with dementia in 3 nursing homes. The results of this study are summarized as follows; There is no wide difference between skilled nursing facilities on the characteristic of living behaviors of the elderly with dementia. Daily living activities and the use of spaces are largely influenced by the daily program and the operation policy of each nursing homes in addition to human relationship of the elderly with dementia. Common spaces such as day room, dining room plays an important role for their daily living activities, because that most of the elderly with dementia stay long during daytime. Layout of each private room and common space seems very crucial point in designing these facilities, in order to enable demented people to live their lives more independently.

An important approach towards solving the scattered data problem is by using radial basis functions. However, for a large class of smooth basis functions such as Gaussians, the existing theories guarantee the interpolant to approximate well only for a very small class of very smooth approximate which is the so-called 'native' space. The approximands f need to be extremely smooth. Hence, the purpose of this paper is to study approximation by a scattered shifts of a radial basis functions. We provide error estimates on larger spaces, especially on the homogeneous Sobolev spaces.

Both shifiting the input signal's frequencies by a fixed frequency and compressing the input signal's bandwidth have been known to be effective in improving the stability margin of public adress systems operating in reverberant spaces. This paper describes the effect of an alternative approach of improving the acoustic-feedback stability and yet maintaining speech inteligibility by bandwidth compression and expansion. Conditions are derived for this technizue to be realized and an experimental system has been made - up. A series of experiments has been performed in small spaces and the results have shown that more than 5dB improvement can be obtained in the stability margin.

In this paper we consider the global well-posedness of compressible magnetohydrodynamic system in ℝ^d with d ≥ 2, in the framework of the critical Besov spaces. We can show that if the initial data, the shear viscosity and the magnetic diffusion coefficient are small comparing with the volume viscosity, then the compressible magnetohydrodynamic system has a unique global solution. Our result improves the previous one by Danchin and Mucha [10] who considered the compressible Navier-Stokes equations.

In the modern society, phenomena such as a decrease in population and an increase in urban small houses caused by demographic changes, a decrease in midium-large housing constructions, and the concentration of one to two person families in the capital area cultivated ground for the growth of small house market. In response to these trends, interior coordination becomes a critical factor to be applied to the small houses in order to suit the residents' needs in most convenient, efficient and aesthetic ways. Therefore, an evaluation element is in demand to extract, evaluate and constantly improve the interior coordination elements. This study extracts and analyzes the essential elements required for small houses into spatial structure, system coordination and interior coordination. In domestic cases, most of spatial structure was conventional and linear while in foreign countries, various variations were found to reflect the needs from different consumers. For the system coordination, convenience played the most important role to emphasize on the easy use of digital system and built-in appliance system in domestic cases. However, in foreign countries, safety issue and economic aspects were the most considered when it comes to the interior coordination. In regard to interior coordination, installations of the storages for the limited small spaces that also support as extended spaces were rare to find in both cases for domestic and international settings. It is expected that systematic studies focused on more objective standards for interior coordination shall be implemented to provide indicators to measure the interior coordination cases in the near future.

The aim of this study is to investigate the present use condition of 145 public open spaces which have not been executed in the Busan Metropolitan City Area. The unexcused public open spaces are analyzed by the zoning, size, shape type and the development planning. First, in terms of the distribution rate by zoning, it is found that the majority of unexecuted public open spaces are located in residential area, especially in the third general residential area. Second, the most shape types are linear forms and the next are indeterminate form and fixed types. Lastly, just a few of the unexecuted public open spaces have the development plan and those are mostly to create a small park or rest area.

The urban style compact apartment which appeared at the end of 1990's was developed by the decrement of household members and in compliance with a new life style. Now it has its own market as a new trend. The purpose of this study is to better understand the characteristics of urban style compact apartments based on an analysis of apartments actually sold on 2008, in order to reflect on the future directions and developments. To support a comprehensive analysis, this study considered three types of compact apartments developed by : a. major developers which own multiple well-recognized brand names, b. mid-size developers under general brand names, c. new or small-size developers specializing in compact apartments. The results from 21 urban style compact apartments could be summarized as follow; 1. Most buyers are Singles or DINKs. The single women occupy a large percentage. 2. Condition of good location is under 5 minutes walk to station and accessibility to 2 and more station. 3. Exterior of building should be harmonious to surrounding and simple, the atmosphere of entrance hall should be warm and relaxed. 4. The spatial character of unit plans are developed by the ways of connecting spaces; 1) Connecting spaces by mobile partition: flexible spaces with expansion 2) Connecting spaces by hall: well arranged spaces with excursion and extends 5. The equipments of kitchen and security are fully carefully planned.

Nowadays the parks in Shanghai tend to develop towards two directions. Small and medimn parks are being gradually transformed from closed management to open management, while large ones emphasize their nature of theme and nature of functions. Simultaneously, the number of large and open public green spaces has been significantly increased. Although the public green space does not adopt the management pattern for parks, there is almost no difference between public green space and ordinary parks so far as the functions and scales are concerned. Due to the fact that there is no obvious boundary between a public park and a public green space, this paper raises a suggestion to coordinate continuously their management and functions so that the distribution of and the connection between the urban green spaces can be more rational and more definite and a sound green network can be formed. Starting from the viewpoint of emphasizing accessibility to green spaces and enhancing the angle of linking green spaces, we aim at transforming a park system to a multifunctional green system, extending the effects and service radius of large green spaces, and strengthening the internal connections with the surrounding areas so that a high-quality green space can be formed with the connection of the green space network.

Coworking spaces have been increasingly considered as a way of building an innovative entrepreneurship ecosystem and facilitating population inflow. This paper aims at identifying the concept and characteristics of coworking spaces and examining these various types in a regional context. Coworking spaces located or planned in small and medium-sized cities and rural areas in Japan and Korea are empirically investigated. Through the case study, this study provides implications for a model of coworking spaces being a creative community in a region. Specifically, it is necessary to have distinctive features only for the regional context-based coworking spaces. Moreover, this new spaces should act as a multi-functional, convergent space and a venue for regional innovation. In a fast-changing work environment such as telework, the region-based coworking spaces can be reconsidered as the place that provides an alternative work, play, learn, and rest platform. Creative people hoping for new work and lifestyle may flow into the region through this intermediator, and thus foster the interplay between the creative community and regional environment.
