It is a trend to pursue the reinforcement of child-centered, play-oriented ecological education programs that support children's development. Most of these nature friendly and eco education is done in the outdoor space. So outdoor activities in child care facilities are essential. The purpose of this study was to analyze the actual condition of the outdoor space for ecological child education in the child care center. Therefore, in order to provide the basic data for the direction of the improvement and to grasp the current situation and problems, the survey and analysis of the external space composition and utilization status in the child care facilities for nature-friendly ecological child care education has been done. As a result, the half of the cases did not reserve even the minimum size of outdoor space and fall short of the standards of outdoor space quality as accessibility, complexity, articulation and nature friendliness for ecological education. Therefore, in order to establish an ecological education environment, it is necessary to build facilities in natural green or suburban areas. In addition, they need to use the natural environment such as parks, open spaces, and forests.

This study aims 1) to estimate the form of living house of pre-urbanization of Inchon, and 2) to ensure originality of to be achieve urban plan and living space plan which is base on local character by 3) arranging changed character of living space through the urbanization sequence by invest of house in natural village at Pupyung. The character of arranging living space of house at Pupyung is placing Sarang-chae(husband's block of house) instead of making another Haenrang-chae (visitor's block of house) and Sarang-chae is attach importance to Man's living space but today, have disappearing the uses of Sarang-bang (husband's living space) because by Man lives An-bang(originally woman's space). The character of plan is arranging room in both side of Maru(wooden living floor) in spite of different structure, and the uses of plan or room is changing to fit to purpose of according to environment of living. Generally, the structure is made by natural stone and cubed column, and used smaller member cause by rare wood material.

The purpose of this study is to provide the guideline of the outdoor space of residential land development district for children's outdoor activites. This study was accomplished by the valuation of the physical environment of 5 residential land development districts, the analyzation of behavioral mapping about children's outdoor activities, and the analyzation of satisfaction and the consciousness of 190 residents(parents) & 230 children. Especially, outdoor spaces were divided into 6 parts (play space, education facility, commercial facility, green space, and empty space & parking lot). And than, 6 outdoor spaces were valuated about the physical characters such as accessibility, network, safety, variety, functional, natural elements. Also, the survey for residents and children's consciousness were used the Likert scale. According to the result of this study, many parts of the housing area were not good for children's activities, and resident's satisfaction was low. In the sample areas, negative factors were car and motorcycle. And many residents were pointed out the lack of natural elements, variety, and safety of outdoor space in dwelling area. Finally, this study suggested the guideline children's activities based on the result of analyzation of valuation, behavioral mapping, and survey.

We have put considerable time and work to find a proper solution to restore the damaged natural environment due to Dam construction, and to restore the field around Dam on the basis of Environmentally Sound Sustainable Development(E.S.S.D). We've replaced the site which had been used as a equipment space with the natural-oriented park, have made a wildlife corridor for those animals which have been living in the area in a newly constructed road to in an out, and have introduced a streamside plant to organize green-space. We've received incredible favor from visitors and residents for the environment restoration. The natural-oriented park plays a role of giving the citizens to the pleasure and the comfort.

In this paper, we establish an evaluation formula to calculate the Wiener integral of polynomials in terms of natural dual pairings on abstract Wiener spaces (H, B, 𝜈). To do this we first derive a translation theorem for the Wiener integral of functionals associated with operators in 𝓛(B), the Banach space of bounded linear operators from B to itself. We then apply the translation theorem to establish an integration by parts formula for the Wiener integral of functionals combined with operators in 𝓛(B). We finally apply this parts formula to evaluate the Wiener integral of certain polynomials in terms of natural dual pairings.

In this paper we generalize the Whitehead theorem which says that a homology equivalence implies a homotopy equivalence for nilpotent spaces. We make some theorems on a homotopy equivalence of non-nilpotent spaces, e.g., the solvable space or space satisfying the condition (T**) or space X with $\pi$1(X) Engel, or locally nilpotent space with some properties. Furthermore we find some conditions that the Wall invariant will be trivial.

Let (H, B, .nu.) be an abstract Wiener space where H is a separable Hilbert space with the inner product <.,.> and the norm vertical bar . vertical bar=.root.<.,.>, which is densely and continuously imbedded into a separable Banach space B with the norm ∥.∥ , and .nu. is a probability measure on the Borel .sigma.-algebra B(B) of B which satisfies (Fig.) where $B^{*}$ is the topological dual of B and (.,.) is the natural dual pairing between B and $B^{*}$. We will regard $B^{*}$.contnd.H.contnd.B in the natural way. Thus we have =(y, x) for all y in $B^{*}$ and x in H. Let $R^{n}$ and C denote the n-dimensional Euclidean space and the complex numbers respectively.ctively.

Wang -gok Villages was forming the space marking the centripetal system from frame composed of adjacent mountains and the cosy and comfortable space perccplively and psychologically, and both the openness and closeness existed together The analysis of the circulation structure in the exterior spaces of home showed that generally one must pass through kitchen to approach to the rear yard having the strong decree of enclosure and privacy. The determinants of the space organization in Wang-gok villages and the exterior of its homes were direction and gradient as natural factor, and traditional thought, action and social class as sococultural factors. The configuration of rear garden was classified into flat type, terrace type and mixed type of natural hill and terrace. The rear garden was created purposely and actively, emphasizing the harmony with and approach to nature.

Rational parameterization of curves and surfaces is one of the main topics in computer-aided geometric design because of their computational advantages. Pythagorean hodograph (PH) curves and Minkowski Pythagorean hodograph (MPH) curves have attracted many researcher's interest because they provide for rational representation of their offset curves in Euclidean space and Minkowski space, respectively. In [10], Kim presented the characterization of the PH curves in the Euclidean space and analyzed the relation between the class of PH curves and the class of rational curves. In this paper, we extend the characterization of PH curves in [10] into that of MPH curves in the general Minkowski space and consider some generalized MPH curves satisfying this characterization.
