The purpose of this study is to find out the changes on the metropolitan apartment unit plans based on the interior spaces for women such as master bedroom, bathroom and attached spaces to the master bedroom, living room, diningroom, kitchen, utility room, and balcony. This study used the content analysis method, space syntax. Contents were the floor plans with 3 rooms type and limited to about $105m^2$ among drawings of an apartment encyclopedia. Above all, 174 unit plans were analyzed until now. Specifically, using $S^3$-Convex program, the integration and control value periodically of the interior spaces for women(master bedroom, bathroom and attached spaces to the master bedroom, living room, diningroom, kitchen, utility room) is understood. Second, using SPSS package 16.0, relative size of the interior spaces for women on the unit floor plan is understood periodically. Finally, the changes on the apartment unit plans based on a woman' aspect after 1980's is reanalyzed.

Many scholars studied the boundedness of $Ces{\grave{a}}ro$ operators between $Q_K$ spaces and Bloch spaces of holomorphic functions in the unit disc in the complex plane, however, they did not describe the compactness. Let 0 < ${\alpha}$ < $+{\infty}$, K(r) be right continuous nondecreasing functions on (0, $+{\infty}$) and satisfy $${\displaystyle\smashmargin{2}{\int\nolimits_0}^{\frac{1}{e}}}K({\log}{\frac{1}{r}})rdr<+{\infty}$$. Suppose g is a holomorphic function in the unit disk. In this paper, some sufficient and necessary conditions for the extended $Ces{\grave{a}}ro$ operators $T_g$ between ${\alpha}$-Bloch spaces and $Q_K$ spaces in the unit disc to be bounded and compact are obtained.

In this paper, we give new necessary and sufficient conditions for the compactness of composition operator on the Besov space and the Bloch space of the unit ball, which, to a certain extent, generalizes the results given by M. Tjani in [10].

In this paper, we give new characterizations of the boundedness and compactness of composition operators $C_{\varphi}$ between Bloch type spaces in the unit ball $\mathbb{B}^n$, in terms of the power of the components of ${\varphi}$, where ${\varphi}$ is a holomorphic self-map of $\mathbb{B}^n$.

In this paper, we prove that for every surjective phase-isometry between the unit spheres of real atomic $L_p$-spaces for p > 0, its positive homogeneous extension is a phase-isometry which is phase equivalent to a linear isometry.

The purpose of this study was to investigate the spatial characteristics of residential and nursing units in large skilled nursing facilities for the elderly that were located in city areas, and to discuss the way for efficient unit care. For collecting the data, the researcher visited 6 facilities to make explorations and to interview the staff concerned. Most of the research facilities had systematic residential units that each unit basically had elderly private rooms and the spaces for small group. The number of elderly residents per unit was appropriate for the limit which was suggested by Kwon(2002), but the sizes of small group spaces were smaller than the standard limit($1.62m^{2}$ per resident). The nursing units were made up of nursing station, 2-4 residential units, spaces for large group of residents, hair dressing, nurse, living assistants, bathing, storage and etc. Some of them had problem in efficiency of space use because they did not have distinct usage. In conclusion, this study suggests that each floor has one nursing unit including 40 residents maximum and each nursing unit consists of 2-3 residential units that have 20 residents maximum per unit. In each residential unit, the furniture and spaces for efficient unit-care should be arranged, such as TV, dining table, kitchenette, bathroom, and rooms for living assistants. The hall type is better for the small group so that it has a transitional characteristic leading to the public spaces. The large group space needs to have clear usage such as conducting program differentiated from small group, and various furniture such as sofa, TV, table, and etc which encourage the elderly voluntary use.

This study aims to obtain new design factors in terms of constructing rural apartment houses fit for the actual farm life. To carry out this study, field studies and personal interviews have been made on the living mode and using realities in the unit spaces of the rural apartment houses. The houses surveyed are the rural apartments in Chungbuk Province which were built by the public program to improve old farm houses. The results are as follows. The living modes .in the unit spaces of the rural apartments are very similar to those of the urban apartment houses. But compared with the urban indoor-living modes, the rural life is keeping more of the traditional sitting way-of-living. Accordingly, it is quite necessary to consider the nature of farm life and the sitting way-of-living in designing the rural apartment houses.

In this paper we obtain some new characterizations of Besov spaces on the unit ball of $\mathbb{C}^n$. These characterizations are also completely new even in the settings of the unit disk.

We characterize two-point homogeneous spaces M by means of the structural operator $h={\frac{1}{2}}{\mathcal{L}}_{\xi}{\phi}$ or the characteristic Jacobi operator ${\ell}=R({\cdot},{\xi}){\xi}$ on the unit tangent sphere bundles $T_1M$.
