The purpose of this study is to provide a practical guide for selecting architectural artwork and analyze relationship between artwork and interior space & facade. The problems with many outdoor artwork did not make the characteristics of the specific environment and did not form a big flow in the urban contextualism. Choosing the artwork, architectural environment for artwork is very much part of the designers' task. When artwork is to be specifically acquired for a particular projects, designer and client must work together to make choices and plan placement. The data are collected through evaluation surveys of college students and graduate students majoring in interior architecture & design, and analyzed by using SPSS-WIN program to find the major characterized factors. It is concluded that architectural artwork should be constituted with nine major factors of interior space - theme/scale, situation/contemporay accord, finished materials harmony, line/two-three dimensional form, proportion/rhythm, sequence, natural/artificial form, abstract/reality expression, originality - and eight major factors of facade - situation, abstract/reality expression, finished materials harmony, theme/sequence, natural/artificial form, proportion/rhythm, static/dynamic expression, originality/. contemporay accord.

Let M be a semi-invariant submanifold with almost contact metric structure (𝜙, 𝜉, 𝜂, g) of codimension 3 in a complex space form M_n+1(c) for c ≠ 0. We denote by S and R_𝜉 be the Ricci tensor of M and the structure Jacobi operator in the direction of the structure vector 𝜉, respectively. Suppose that the third fundamental form t satisfies dt(X, Y) = 2𝜃g(𝜙X, Y) for a certain scalar 𝜃 ≠ 2c and any vector fields X and Y on M. In this paper, we prove that if it satisfies R_𝜉𝜙 = 𝜙R_𝜉 and at the same time S𝜉 = g(S𝜉, 𝜉)𝜉, then M is a real hypersurface in M_n(c) (⊂ M_n+1(c)) provided that $\bar{r}-2(n-1)c{\leq}0$, where $\bar{r}$ denotes the scalar curvature of M.

On this research. The method of space analysis(Space syntax) is used to investigate the relation between composition and configuration in the houses of four modern architects. Space analysis represent that the houses permutate the morphological properties of depth and rings to embed domestic fuctions within the hoe and to interface household memgers. Two of the house are judged to be well composite but banal: The other appear more inventive in relation compositinal principles to space configuration, to create a measure of subtlety and richness in life style which is lacking in the examples where form is manipulated in the abstract. On this research. It is discoverd that Knowledge of both the internal laws of form and the social logic of space is required to generate the practical conjunction of formal rigour with fuctional ease which we recognise in the houses of architects.

Clothing shape is principally described in seven factors that are composed of clothing design, clothing material, clothing size, pattern design, sewing method and body motion etc. The aims of this study was to measurement out-line space-shape variation of clothing fitness with body by using the image processing. The subjects for direct anthropometric measurements were 248 female college students aged from 19 to 22. The data were statistically analyzed by principal analysis and cluster analysis. The results selected one somatotype. for the out-line space-shape variation of clothing fitness with body, there dimensional clothing shapes measured. and cross-sectional clothing shape obtained by the measurement was considered to be space wave form. The out-line space-shape variation of clothing fitness with body was observed between the node number and amplitudes of clothing wave form, and node number was determined at the maxim of space-shape amplitude, and the space-shape amplitudes have related with aspect ratio of cross-sectional shape.

The purpose of this study is to suggest the direction of the specialized dementia hospital which can confront in the old age society of Korea changing quickly. We need to make the architectural planning guide including the form determining factors which is useful for the domestic dementia hospital. The factors can be extracted from a database by analysing and investigating the documents of the developed nations equips the excellent dementia hospital. The result of this study is like this : at first, it is very important that the patient has to have the feeling of comfort and familiarity through the external space leads a direct participation. Second, the interior space must have the composition for the patients primarily. So, this research can be used the basic document of the dementia hospital planning.

Recently, the studio which is urban housing form is rapidly growing up by new residential space according to increasing 1~2 person households form because of Modern members who have changing patterns of life and diversification of social values. The resident of the studio who lives or uses the space for a work such as students, office worker and soho-jok has various characters by a society nature changes and a regional peculiarity. The studio form and function is getting change according to variety trend changes and their life styles. The role and use of residential space also have variety such as the resident who lives in the studio. This study is to find the space utilization for them and reasonable housing solution in that structure, furniture and Wall Storage System of existing studio which is based on the common life patterns. The study's purpose is to propose the furniture design of changeable Wall Storage System according to the analysis.

We study lightlike hypersurfaces M of a semi-Riemannian space form $\tilde{M}(c)$ with a semi-symmetric non-metric connection whose structure vector field is tangent to M. Our main result is two characterization theorems for such a lightlike hypersurface.
