This paper addresses the issue of estimating regression function with errors in variables using wavelets. We adopt a nonparametric approach in assuming that the regression function has no specific parametric form, To account for errors in covariates deconvolution is involved in the construction of a new class of linear wavelet estimators. using the wavelet characterization of Besov spaces the question of regression estimation with Besov constraint can be reduced to a problem in a space of sequences. Rates of convergence are studied over Besov function classes $B_{spq}$ using $L_2$ error measure. It is shown that the rates of convergence depend on the smoothness s of the regression function and the decay rate of characteristic function of the contaminating error.

Space dominates all the art activities human do and plays a role of providing aesthetic emotion. Architecture, sculpture, painting, and furniture, etc. these two and three dimensional works are represented in space and interpreted the role of its form, structure and function. Each area is different, but space has been studied in philosophy, physics, geometry, and mathematical studies, etc. and has been consistently interpreted and represented relating to a variety of human creative activity. Furniture is also three dimensional art being dependent on space. In the United States in 2004, I made the living room bench by applying the spatial concept at Rochester Institute of Technology. Two years later, this design was adopted by wendell Castle Collection, an American furniture company, then prototype were made and tested three times during a year, and then since 2007 as indoor benches it has been manufactured in the United States. The study's purpose is to order the process of its development based on the experience of bench production applied the spatial concept, and by analyzing the properties of spatial concept, I am planning to propose a new concept on interaction with the space and furniture for next.

This landscape design proposal was presented to a design competition for the KangWon Province Police Agency(KPA). The site, about 27,711 $m^2$, is located at 293-4 Udu-dong, Chunchun, KangWon-Do. Design objectives of the KPA were to build a symbolic place which fall community members with pride, to elevate an identity and status of the KPA by creating a landscape correspondent to the concept of the building design, to provide community residents with a space to enjoy cultural and social activities, and to make environment friendly space. The main concept was developed by one of characteristics of the traditional spatial structure of Korea known as an, 'Open and Closed spatial structure.'By re-interpreting the traditional spatial structure and applying it to the site, the design met the various desires of the KPA. The site is primarily segmented into 6 sub spaces; entrance space Podori plaza, symbolic court, police billeting area, sports area, and rear rest area. The entrance space, Podori plaza, and symbolic court on the south-west part of the site represent the publicity of the site as the concept of ″open space.″ On the contrary, considering the specialty of police affairs, the north-east part of the site, which contains the police billeting area and rest area, were designed to maintain security by using the concept of ″closed space.″ To express an identity of the KPA, 'Podori', a police mascot, the plaza was designed and is suppose to function as the hub of the community. In the front section of the plaza, a symmetrical planting pattern, centering the strong axis, was introduced to strengthen its symbolic meaning. Traditional window frames such as the pattern of 'Pisal-jige'and 'Umulsal-jige' were used for the paving system which is applied as the environment friendly design. Site facilities and furnitrue were placed at every important spot in order to connect various spaces organically. As these well-tied spaces properly shared their function, spatial sequence and management would be promoted. The entire space was designed to allow free access of handicapped people. This proposal is meant to create a new image of KangWon province and to enhance the way of inhabitants' think about their community.

In this paper, the probability that a given point is covered by a random convex hull generated by independent and identically-distributed random points in a plane is studied. It is shown that such probability can be expressed in terms of an integral that can be approximated numerically by function-evaluations over the grid-points in a 2-dimensional space. The new integral representation allows such probability be computed efficiently. The computational burdens under the proposed integral representation and those in the existing literature are compared. The proposed method is illustrated through numerical examples where the random points are drawn from (i) uniform distribution over a square and (ii) bivariate normal distribution over the two-dimensional Euclidean space. The applications of the proposed method in statistics are are discussed.

University is very big scale among urban facilities as for single facilities and there is characteristic that accompany various university support functions in contiguity area. Width that have diverse spatial configuration generally our country university campus around was formed, this does function that connect university and ambit. Specially, formation enables change of spatial configuration that existent width system has if is new around university campus. Also, can form more animate and lively width spatial configuration by forming more various and complex width spatial configuration in width had formed in existing. It is that search special quality of university surrounding width spatial configuration analyzing existing width spatial configuration of Kangwon National University back gate by formation if this study is new in city and forecasts the change, and used space syntax by spatial configuration analysis method.

In this paper we introduce some new types of double difference sequence spaces defined by a new definition of convergence of double sequences and a double series with the help of sequence of Orlicz functions and a four dimensional bounded regular matrices A = (a_rtkl). We also make an effort to study some topological properties and inclusion relations between these sequence spaces. Finally, we compute the closed ideals in the space 𝑙²_∞.

Spatial perception and spatial structure that focus on psychological effects produce a real force through the medium of space that can control human actions, even their psychology. The job of understanding the characteristics and effects of architectural spaces that recognize the relationship between architecture and human beings, including the psychological dimension, is an alternative search for quality spaces that can increase the mutual relationship between space and human beings. This paper introduces two propositions called "space" and "psychology" in order to discover a meta-pattern connecting space and the human mind with the aim of systematizing that internal network and establishing a new architectural system concerning space and human beings. This paper also proposes a method of accessing physical spaces that can affect psychological states through a conceptual substitution called "extension," with the aim of discovering the implications inherent in such extensive relationships and proposing a methodology of organizing psychological spaces based on the characteristics of that extensive connection. The means of extensively connecting psychological spaces were classified into the three categories of memory system, sensory system, and motor system, and their corresponding extensive connection characteristics called "simultaneous relativity," "non-mediated immediacy," and "purification process" were also derived. These characteristics accelerate the changes in psychological intensity and function as principles that organize psychological space.

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.
