The construction can proceed in different ways according to the acquired profitability of the hospital during the construction and to the features of departments or areas. This study is an analysis of remodeling construction processes to resolve major tasks of remodeling. The remodeling strategies gained from this study can be summed up as follows: 1) Remodeling work in hospitals involves the acquire relocation of space through extensive area renovations and then moving back to the space, and lastly working on the empty space. Thus, it is more advantageous in terms of construction work to demolish the existing buildings than to acquire the relocation space through extensions or renovations. That is, demolition after the maximum utilization of the existing buildings is the most desirable in terms of space availability. 2) The construction methods for remodeling are two: a method of carrying out construction by dividing the plane areas into several individual ones and of working on it floor by floor. In case of ward areas, and the outpatient area, the construction proceeds after securing the relocation space and partially setting construction areas in order to minimize the decrease in profitability due to the smaller number of beds and treatment rooms during construction. If the outpatient diagnosis/ treatment area and the supply area relocate together with the ward areas, there may be extra expenses. Thus, doing construction by area, while partially operating those areas or after relocating the whole areas.

가장 많이 활용하는 청소로봇의 청소기법은 크게 랜덤기법과 바둑판식기법으로 나눌 수 있다. 랜덤기법을 이용한 청소로봇은 장애물을 만날 때까지 직진 방향으로 청소를 수행하며, 장애물을 만나면 일정한 각도로 회전한 후 다시 직진 방향으로 청소를 수행한다. 랜덤기법은 중복적인 청소를 수행하는 문제가 빈번히 발생하며, 청소를 완료하는 데 오래 시간이 소요되는 단점이 있다. 바둑판식기법을 이용한 청소로봇은 장애물을 만날 때까지 직진 방향으로 청소를 수행하며, 장애물을 만나면 직진과 회전을 이용하여 청소가 수행되지 않은 위치로 이동하고, 이전에 청소를 수행한 방향의 반대로 청소를 수행한다. 바둑판식기법은 청소공간을 조밀하게 청소하며 진행하기 때문에 장애물이 없거나 작은 공간에서 작업 성능이 뛰어나다. 그러나 바둑판식기법으로 장애물이 있거나 복잡한 공간을 청소할 때는 청소시간이 증가한다. 그러므로 청소의 효율성을 증가시키기 위해서는 작업공간을 정확히 파악하여 청소를 계획적으로 진행해야 한다. 본 논문에서 제안한 가상지도 기반 청소로봇은 작업공간을 효율적으로 청소하는 특성을 갖는다. 시뮬레이션을 통해 제안한 기법의 효율성을 측정하였다.

In this work, we establish Heisenberg-type uncertainty principle for the Bessel-Struve Fock space ${\mathbb{F}}_{\nu}$ associated to the Airy operator $L_{\nu}$. Next, we give an application of the theory of extremal function and reproducing kernel of Hilbert space, to establish the extremal function associated to a bounded linear operator $T:{\mathbb{F}}_{\nu}{\rightarrow}H$, where H be a Hilbert space. Furthermore, we come up with some results regarding the extremal functions, when T are difference operators.

An Apartment Veranda is a transitive space which is being used for many different purpose. A Rear Veranda which is connected to the kitchen is an important space for the housekeeping work and it should be planned carefully to reflect the rational and functional designs. Therefore the objective of this research is to suggest a systematic basis for the practical space planning of the Rear veranda that meets the varied needs of consumers by examining its usage pattern through the analysis of the apartment occupant's behavior pattern stored item the degree of satisfaction and consumer requirements. The research was conducted mainly on apartments built after 1990. The following are the conclusions from the research : 1. Most of the research respondents were aware of the absolute need for the Rear veranda. But they expressed dissatisfaction with the space usage. This indicates that the Rear Veranda planning does not reflect the functionality of the space and concentrates on the idea of providing consumers a service space based on the size of the apartment instead. 2. Although the Rear veranda is used as the multipurpose housework space it is mainly used as the laundry and storage space. This shows a big deviation from the concept of the utility space. Because the behavior pattern associated with the Rear Veranda is largely influenced by the traditional life pattern the development of the Rear Veranda as an exclusive space for the housekeeping work. 3. According to a high frequency of the storage of the laundry related item in the Rear Veranda indicated by the research the Rear veranda is used as the laundry room as well as a auxiliary storage space by most people. The installation of gas range is expected to increase due to the expansion of the usage function of the Rear Veranda space. The installation of a specialized refrigerator to store the traditional food is demanded. 4. Consumers need more efficient and functional storage device because the temporary shelves are often being used as the storage device. The perception of the storage device is assumed to have been influence by the traditional life style.

Regarding leisure and work as very important in residential life of old ages, this study analyzed their preference by leisure and work for senior congregate housing, which can provide proper work and leisure activities for older people who are able to manage their social activities with healthy condition. It conducted a survey of middle aged of the 50's who would face problems of senior housing in 2010, with stratified sampling by region, sex and housing structure type. Totally 556 Questionnaires were used for the final analysis. The research results showed that, first, the group which was positive toward their works mostly had spouse of the age of early 50' s and work for professional, technological, managerial positions with good health. Second, the more positive group towards their work showed high willingness to move in senior congregate housing, than a negative group towards their work, and put a weight on the openness of shared space and facilities as well as various alarming equipments, common space, common programs and the ability of managers. Third, according to the attitudes toward leisure activities, there were differences in each group by housing structure type, education of their own or their spouses, monthly income, property, economic ability, health condition, living together with spouse, housing tenureship, and usable area of houses. The fourth was that those who enjoy active leisure activities presented high willingness to move in senior congregate housing than those of negative attitude and also there was a difference in managerial ways. Throughout the results of the study, it appeared that a group of positive attitude toward work and leisure, than that of negative attitude, recognized the importance of senior congregate housing which social and leisure programs could support. It implied necessary to develop housing for the older people who have enough ability to manage their leisure activity as well as their work. The study is likely to have a contribution to suggest practical data for helping the development of housing for self-reliant seniors by analyzing their preference on senior congregate housing by their attitudes toward work. The research for the factors of various designs and managements by leisure and work may become the following research theme of the study.

The change towards meeting diverse customer needs has started to affect the hotel industry as well. Design hotels emerged as customers demanded differentiated lodging experiences they could not fulfill at franchise hotels which were uniform in style everywhere in the world. Design hotels are meant to provide a new concept of space through unique design sensibility and work of designers, which highlighted the role of interior design. This research analyzes the characteristics of indoor space expressed in design hotel common spaces by the French designer Andree Putman, also known as the founder of boutique hotels and the concept of design hotels. As the original founder of the concept of design hotels, Putman's scope of work stretches wide, from interior design to product design. She is also one of the few French designers with a modernist inclination. The research runs a review on previous literature, characteristics of design hotels according to design tendency, and the association with characteristics of indoor space designed by Andree Putman, followed by case analyses extracted by analyses on design characteristics of common spaces she has designed. The analysis reveals that she creates comfortable yet elegant space, using contrast and fusion arising from negotiation of design styles to interpret space, the sense of spatial balance and understated expression of order through symmetrical structures, diverse creation of space through geometric structuring, highlighting indoor space by utilizing lights as objects, and the heterogeneous harmony achieved by contrasting juxtaposition, and understated formativeness. It is expected that study results would be utilized as methods of new designs of interior space in design hotels.

Nature/Landscape is surrounding space in which we make living. It is considerably comprehensive tenn. but on the other hand, the site can be existence, experience, and certain circumstance with boundaries. Based on these places, through contemporary art criticism, this study is to contemplate how art since 1960s, especially, site-specific art in three-dimensional space intervene in the environment. Artists of today put more value on the process and act of art making founded on the external, and they tend to create the characteristic of site or to indicate linguistic documentation. Moreover, a large-scale tendency of contemporary sculpture and 'occupation of specific site' seems to accede spatial conception from architecture. The core that recognizes these artworks is with body, that is to say, the space in which Self becomes the subject by changing the structure of the work while moving around it. In particular, 'Site-specific Art (in situ)' sometimes determines the form inward or outward It also relates directly on viewer's five senses by looking, hearing, and feeling, touching, and interacting. For example, in Richard Serra's , the viewer who moves around the work has the role to manipulate the movement of the work by perception. Works of In situ and works that planned for specific site suggest 'occupation of site' as of the function of the work These sites are ideal and special as well as being independent. Ultimately, it seems that the creative process of contemporary artists is to carry those intended form on the structure of perception. Furthermore, law of nature such as entropy, and acceptance of contingency helped organic structure of artwork become more abundant. For Robert Smithson, entropy suggests of reaching to a state of equilibriumin which everything is the same. This means that any core is justifiable and any rank is possible. Because the world without a core is a labyrinth of boundless exploration.
