This paper proposes fast speaker adaptation method using artificially distorted speech in telematics terminal under the car noise environment based on eigenspace-based maximum likelihood linear regression (ES-MLLR). The artificially distorted speech is built from adding the various car noise signals collected from a driving car to the speech signal collected from an idling car. Then, in every environment, the transformation matrix is estimated by ES-MLLR using the artificially distorted speech corresponding to the specific noise environment. In test mode, an online model is built by weighted sum of the environment transformation matrices depending on the driving condition. In 3k-word recognition task in the telematics terminal, we achieve a performance superior to ES-MLLR even using the adaptation data collected from the driving condition.

In modem buildings, the concept of open-space plan gets more acceptance as it supports more flexibility for the internal space design. This open-space can be easily subdivided by internal partitioning to provide each individual working zone. Although the partitioning forms each physical working zone, its indoor environment could be different Iron what the occupants require. Especially the air movement and contaminant spread in each working zone could be blocked or distorted by the partitioning, which may produce unexpected change in ventilation performance designed.

Increase of aging population and demands for care and support systems, needs and demands for a variety of care services and housing facilities have increased. With the emergence of gerontechnology, tangible and intangible technologies and innovations have been explored and developed in many countries. Since housing environment is very important to define well-being and quality of life of the elderly, technology applications in the living environment are considered as important means. The purpose of this study is to enumerate and investigate technologies for the elderly to assist daily living and help care providers, and to explore technology applications in the built environments. This study also investigate how intelligent technologies are installed in the built environment and physical consideration for a variety of approaches. The content analysis was conducted to investigate technology developments for the elderly based on web materials and publication materials. The seven examples were chosen since they are seeking technologies especially for the elderly or aging-in place. General goals for the diffusion of intelligent homes expecially for the elderly are to be easy to install and remove, unobtrusive, redundant cueing, easy to use, and robust. The results of this study suggest application considerations for the technologies of the built environment for the elderly.

In the 21st century, Korea had radical economic development with accelerating urban sprawl, and following declination with social polarization. City declination makes socially vulnerable people unstable and increase homelessness. The projects revitalizing decayed area utilize local idle spaces to build new facility with creative supportive programs. The purpose of this study is to analyze inclusive characteristics of a supportive housing 'The Brook'. A field visit walk through observation and in-depth interview were utilized as research methods. The information of a representative supportive housing field will promote understanding the concept, and create base for further research. As results, state and knowhow of information concerning housing first policy, active government investment, space planning, management, social integration, service providing, architecture and so on offered to facilitate inclusive insights. In conclusion, the characteristics of supportive housing were realistically analyzed through a field research. This research is significant to introduce initially the effective supportive housing which has been practiced for 30 years in USA to that needs alternatives for the socially vulnerable in Korea.

The purpose of this study was to analyze the perception among participants in the Built Environment Education(BEE) programs for children. And also, hopefully, we would get some strategies for development of BEE program through post-evaluation. The survey was conducted by the students and the parents who were participated in the four BEE programs. The key results are as follows: 1) The way of participation in the programs was limited. We should consider public relation strategies and its sustainable curriculum. 2) The students felt easy to learn from the lecture, but we need to consider the students' ability in craft activities and the level of school grades. 3) Most of the participants was satisfied with the programs. For students, the 'Educational Environment(Hours & Facilities)' was highly correlated with overall satisfaction. On the other hand, in the case of parents, the 'Teacher' was highly correlated with overall satisfaction. 4) Parents were aware of the need to link the BEE program to school education such as a subject of 'Creative Activity.' The BEE as an integrated program would be a school curriculum or contents of STEAM education. At the end of this paper, the meaning of this study was discussed.

Like other artificial architectures, the residence is also hard to be changed after once it has ever been built because its life is approximately estimated up to 20years. Furthermore, it may give big effect to residents as the life Quality. Because of these specificities, it seems to be important to forecast how demand of residential market will be changed and what kind of residential environment should be built in the future. First of all, we should consider about what is a current situation of residential environment in this country before beginning researching resident preferences. In addition, we will also research current and new residential style in other country, which should be concerned in. Finally, this study is researched by domestic male and female residents in their twenties and four ties on purpose to gain information what type of resident style they want and to suggest new ways of future residential environment.

Urban architecture density is getting higher, and this trend is expected to continue in the future. Therefore, skyscrapers are being brought into relief as future alternative architecture beyond symbolic meaning in the aspect of demand and supply of urban space. However, skyscrapers which were newly built have many problems such as consumption of enormous amounts of energy, destruction of natural environment, and traffic jam. For this reason, environment-friendly skyscrapers based on the concept such as Green Building and Green Skyscraper started to be built around the world. However, plans or evaluation standards, which take account of the environment-friendly aspect of skyscrapers, leave much to be desired. And especially it is hard to find environment-friendly skyscrapers. Therefore, this study aims to establish the concept of environment-friendly skyscrapers that has not properly been defined, and to find realistic planning methods and practical alternatives through the analysis of the works that have brilliant ideas about environment-friendly architectural method. From the perspective of architectural planning, we did case analysis focused on site planning, form planning, elevation and floor planning, and tried to give useful ideas for high-rise architectural planning in Korea by finding practical solution focused on the active use of natural energy, saving resources, the reduction of wastes, natural architectural environment design and natural friendly system from the view of environment-friendly technological analysis.

Eight aromatic hydrocarbons were quantified in a newly constructed building before occupancy during the period of November 1997 to January 1998. Air samples were collected in 6 L stainless steel canisters for 8 hours based on working hour. It was found that the measured total concentration of aromatic hydrocarbons decreases rapidly with time up to a steady-state value. However, the fractions for each aromatic hydrocarbon were greatly changed with time. The concentration ratios of indoor to outdoor for aromatic hydrocarbons are greater than 1 during early period of the measurement, and the ratios decrease with time. The concentrations of toluene, m+p-xylene, ethylbenzene, and o-xylene are much higher than those of styrene, 1, 2, 4-trimethylbenzene, and 1, 3, 5-f trimethylbenzene in indoor air. The concentration fractions of m+p-xylene, ethylbenzed, and o-xylene in indoor air are about twice as hight as those in outdoor air measured during the similar period. It was concluded that the aromatic hydrocarbons were emitted from building materials, paints, and adhesives in an-built building.

Fouling by solids and microorganisms is the major obstacle limiting the efficient use of membrane wastewater treatment. In our previous study, two stages microalgae/membrane filtration system was proposed to treat anaerobic digested palm oil mill effluent (AnPOME). This two stages microalgae/membrane filtration system had showed great potential for the treatment of AnPOME with high removal of COD, $NH_3-N$, $PO_4{^{3-}}$, TSS, turbidity, and colour. However, fouling behavior of the membrane in this two stages microalgae/membrane filtration system was still unknown. In this study, empirical models that describe permeate flux decline for dead-end filtration (pore blocking - complete, intermediate, and standard; and cake layer formation) presented by Hermia were used to fit the experimental results in identifying the fouling mechanism under different experimental conditions. Both centrifuged and non-centrifuged samples were taken from the medium with 3 days RT intervals, from day 0 to day 12 to study their influence on fouling mechanisms described by Hermia for ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) filtration mode. Besides, a more detailed study on the use of resistance-in-series model for deadend filtration was done to investigate the fouling mechanisms involved in membrane filtration of AnPOME collected after microalgae treatment. The results showed that fouling of UF and NF membrane was mainly caused by cake layer formation and it was also supported by the analysis for resistance-in-series model. Whereas, fouling of RO membrane was dominated by concentration polarization.
