Let $1{\;}\leq{\;}p{\;}\infty{\;}and{\;}{\alpha}{\;}>{\;}-1$. If f is a holomorphic self-map of the open unit disc U of C with f(0) = 0, then the quantity $\int_U\;\{\frac{$\mid$f'(z)$\mid$}{1\;-\;$\mid$f(z)$\mid$^2}\}^p\;(1\;-\;$\mid$z$\mid$)^{\alpha+p}dxdy$ is equivalent to the operator norm of the composition operator $C_f{\;}:{\;}B{\;}\rightarrow{\;}A^{p,{\alpha}$ defined by $C_fh{\;}={\;}h{\;}\circ{\;}f{\;}-{\;}h(0)$, where B and $A^{p,{\alpha}$ are the Bloch space and the weighted Bergman space on U respectively.

The art museum plays a role as a cultural space that can solve the cultural desire of people and see a good art works. It is in exhibition space that they personally exchange the feeling between an art work and a viewer in art museum. The types and works - a fiber, a photo, an establishment that needs many places, devices, a video art, and an action art called "performance", cultural art - are shown in small art museum. Moreover, exhibition spaces are modified into the space of another art activities like dancing, music concerts in small art museum because it has no profit space for diverse art activities. And the exhibition the characters of the exhibition space in small art museum. So, it needs to change the characters of the exhibition space in small art museum. Under these background, this stud\ulcorner surveys and analyzes the exhibits, the organization methods, the modified conditions, and the scale of the existing exhibitional space in small art museum. Therefore, the goal of this study is to suggest the composition of the exhibition space unit considering the function and the multifunction in minimum art museum and small art museum.

With the change of family type and diversify of life style, residents need various unit plan in Quality. A rate of economically productive women has increased, and generally double-income households will continuously increase in the future. So a research is requested to consider the double-income households's satisfaction for a unit plan based on their life characteristics. The purpose of this study is to find out double-income households's lifestyles, and to search and analyze users' needs for spatial composition according to their lifestyles, and then, embody spatial composition of Apartment Unit plans. The findings are as follows. (1) Housing lifestyles of users living in apartment are categorized into 5 types: seeking the way to make housework easy and comfortable, making the best use spatial composition, pursing the universalism, housework oriented, pursing the leisure. (2) The type of seeking the way to make housework easy and comfortable requests facility with home appliances and a shower bath, the type of making the best use spatial composition requests storage space and trial about new plan, the type of pursing the universalism is concerned about the protection of environment and a memorial service, the type of housework oriented wants a talk with their family and discuss some problem, and the type of pursing the leisure requests division of household with their family and likes traveling and sports.

The purpose of this study is to analyze the planning concept and spatial characteristics of the multi-housing units in prize-wining works of design competition since 2007. Literature review and content analysis were used for this study and 199units over $59m^2$ were analyzed to review the planning concept, spatial composition and layout. The results of this study were as follows; 1)The planning concept of these units were divided into three aspects; that is, eco-friendly, rational and sustainable unit plan by means of functional, environmental-friendly and future-oriented aspects. 2)Most unit plans had 3LDK+2bath and 4Bay types including family room as a public space. This results shows that family-room and bathroom has recently become more important than number of rooms in multi-housing units planning. 2)In terms of the spatial composition of LDK and Master Bed room, LDK area become large, open type and master-zone were showed 'bed room+dress and powder room+bath' type. 3)The entrance has a intermediated space as a balcony or a former space and the privacy of LDK space was protected from the entrance. This study has a significant moaning on grasping current trend in Korean multi-housing and to provide Information for future direction on housing-unit design.

Purpose: The Intensive Care Unit (ICU) is an important inpatient care area where critical patients are treated intensively with advanced medical technology. The level of care of ICU and the modernization of related facilities is an important indicator of health care quality. At the present time, when the Regional public hospitals are frequently expanding, the rational planning of the ICU has become an important part of the medical institutions treating the ICU. The purpose of this study is to present basic data with net area which can be used in the architectural planning of the ICU. Methods: The investigation and analysis of the ICUs were conducted on 26 medical facilities, based on theoretical analysis through relevant guidelines, articles, and documents, and on the basis of the actual space composition and net area analysis through the architectural drawings. Results: This study provides basic data such as zone division, spatial composition, relationship between main activities and zones, composition of facilities in the zone and area ratio within each zone. Implications: The results of this paper are expected to be effective reference materials for future research for rational spatial organization and efficient operation of the Intensive Care Unit in regional public hospitals.

The recent change of social environment has influence on the configuration of space for the social welfare center. And so the relation of space and function required the change of spatial configuration. The social welfare center fills the role of family welfare, domiciliary care, community organization etc. In such sence, this study explore the conditions of spatial configuration for the domiciliary and community care unit of social welfare centers in small city. For this study, it was investigated the space role and funtion, the service program, the usage characteristics, the room satisfaction of social workers. In sum, the useful data were collected, analyzed, and colligated by case study. It could be used in the design criteria of domiciliary care unit for the social welfare center in small city.

There are many ways to know the social and cultural level of each country. Among them, a museum are not only the best place to understand the history, the life style and the culture level. The most important constituent, which museum architecture has, are visitors, exhibition and communication between visitors. Exhibition space composition is the one of important things in museum architecture, and it's essential to show an intent of exhibition to visitors. This thesis has the purpose to provide the basic material through analyzing exhibition space composition and exhibition method of the theme museum and understanding the relativity of them so that the new theme museums can be designed in the Tight direction. So I chose the independence museum that opened within recent 10 years, finally middle & small size's theme museum were selected. The results from the case study are as follow. Firstly, the exhibition space unit of basic type and center-hall enter type had a one-way for gateway and used the exhibition of three or four faces. The exhibition space unit of around tile center-hall type and guidance type had the separated gateway and used the exhibition of one or two faces. Secondly, the exhibition method of selected museums was divided into the wall face type and the island type. The exhibition method of two faces mainly used in guidance type caused complicated visitor circulation. In that case, it seemed to be good that two walls were used alternately. Thirdly, there were visual type, audio-visual type, handling type and experiential type in the method of exhibition. The former two types were used mostly, and the latter two types were rarely used. Fourthly, the wall face type was inefficient for exhibition because given walls were supposed to be used. Therefore, it was more effective to use the wall face type and the island type together.

Purpose: This study aims to suggest the spatial composition and area of the intensive care units through analysis of current situation for the standards establishment of the intensive care units in public district hospitals in the future. Methods: Three Methods have been used in this paper. 1) Literature reviews about composition, location, foreign standards on intensive care units. 2) Comparative analysis on the architectural drawing for the space program and the area. 3) Field survey in order to confirm differences between architectural drawing and current situation. Results: 1) The intensive care units is required to be linked by the operating department, the emergency department and the sterile supply department upon considerations of accessibility of emergency patients and the infection control. 2) The intensive care unit consists of five areas such as the patient area, the medical staff area, the material and equipment area, the patient family area, and the public area. 3) The location of spaces in the intensive care unit is classified by three methods such as connection by view, circulation and connection to corridor. The [table 20] summarizes the type of space and the average size of the space in intensive care unit. Implications: This study is a basic research for guideline of intensive care units, and need to be followed by further study using various perspectives and methods in the future.
