The extensive coverage and high speed of communication network, which is a basic structure of the information society, enables the provision of various forms of informatiov. especially, such services as cyber medicine, cyber education, home office, home banking, and home shopping will be common; and, now, no one can deny that the information society starts to be part of our life. Regarding home office, John Navigate predicted home office through the electronic house in New Mecca Trend and Alvin Toffler asserted in The third Wave that people could do their work anywhere including living room in their hoses with the development of communication technology and other related appliances. Such predictions are realized with the development of information communicatiov. Therefore, housing space should be changed according to the realization of home office and the direction of housing plan need to be set for home office.

The development of digital culture has brought radical change in the fundamental concept of what workspace is defined by and has also switched the cognition of workspace originally being a place to spend time and do activities regarding tasks into space more than just that. If we take a look at the cases overseas firms have announced after the year 2000, we can find distinguishing facts different from the existing workspace composition, like creative workspace, amusement workspace, workspace for communities, etc. Thereupon, the goal of this research is to look into the domestic characteristics of workspace by investigating and analyzing case by case targeting domestic firms. This research is to first comprehend the theoretical study of workspace, the changing environment, and the characteristics of domestic workspace, going on to utilizing the information achieved above to analyze 8 appointed domestic firms as examples. Contemporary domestic workspace is defined not a place only for activities regarding work tasks but rather a place comfortable and friendly in the concept of a second residence, community node for sharing knowledge and information, mobile space for the digital nomads, and space for coincidental encountering and communication. Based on this the analyzed characteristics of contemporary domestic work places are metaphor, convergence, beyond boundary, and emergence. The characteristics mentioned above are considered elements that increase corporate profits by managing efficient smart-work and producing creative ideas. Therefore, I believe continuous research and development related to this subject is necessary.

The purpose of this study was to analyze daylighting performance in a semi-infinite size office space for lighting energy conservation. DOE2.1E was used for simulations for the model space of $12\times12\times2.6m$. Nomographs were developed which could simulate work plane illuminance, glare index, energy consumption rate and energy reduction rate for daylighting design. Major results of simulations are as follows ; 1) When blinds facing south were installed, 43% of workplane illuminance diminished, but the flare index didn't exceed the recommended max-glare value. 2) In a semi-infinite office space facing south. energy consumption rate in the case space of 500 lux workplane illuminance is larger then case space of 300 lux workplane illuminance. Therefore, energy reduction rate is increased when the semi-infinite office faces south and naintains 300 lux workplane illuminance level.

The purpose of this study is to find out the characteristics of the office space as designed by Gwathemy Siegel and thereby to understand the current trend of interior design of working space in the United States. Unlike most architects, Gwathmey Siegel have extended themselves into interior designing of over twenty offices including law firms, financial institutions and design firms and have successfully won reputation as interior designers. They have distinguished themselves by their ability to turn up and take advantage of the possbility of shaping in a given structure. Their liberal use of fixed furniture and architectural lighting , in addition to ceilings and walls , set them apart from others in the field . The major design elements and principles of Gwathmey Siegel include, among others : 1) Curved and slanted walls on the floor plans endow the office space with forms. Fixed furniture and architectural lighting frequently serve as from -creating elements. 2) The openness of the reception and waiting areas and the irregularity of the corridor walls add a sense of variety in the office. 3) In terms of color and materials, subtle changes of texture and value and the various patterns of joint lines further enrich the space. 4) The principle of symmetry , rough or partial , as applied in the layout of rooms and furniture creates a sense of balance in the space.

Recently, it appears several counterproposals about desirable figures of urban architecture. All of them proposes 'publicity' with cohernt tendency. The reason why it concentrates quantitative expansion of city without united design by urban plannar is that neglect quality values of city. As a solution of poor environment, there cue out the various efforts, about problem of each building, problem of city space, problem of laws and so forth. The reason why necessity of public space was embossed in that architecture extend the activity of citizen and make up the city space. But, each building pursues the private interest, so it is difficult to secure a public space with a high hand. Thus, architecture law has been revised in 1991 and bring the system of open space to match up the publicity and the private interest. Actually, western country brought it and obtained excellent results. While quantity of open space have increased since 1991, a lot of problems revealed in real usage and quality. By means of problem's solution, this study focus on the diversion of recognition for necessity of various open space. In result, on the occasion of approach and openess, except for several building, most glass a facade and the pedestrian can approach easily. Moreover, office buildings near the subway station connected with their low floor. So, the office buildings give openess to pedestrian and a people can approach easily to the buildings. On the occasion of amenity, most have bank and lobby on the first floor and have facilities on the underground floor. It leave open. But the reason why they have bank and lobby is that the space is dry and boring(without elements of nature and rest space). Hence, to make a space full of vitality, it have to plan various design elements and facilities. First of all, plan of indoor public space have to make up facility for the public interest. This study is basic investigation for necessity of indoor public space and through the survey of office buildings, it analyze the character of plan and find out the method of publicity's realization.

This study is to analyze the building layout of traditional government office building in Chungchong province with Chungchong-do regional maps and Eupjis(邑誌) being compiled in the late Chosun dynasty. The building layout of government office in Chungchong-do is followed in the wake of the spatial structure, Sam-Jo(三朝, three reign) and Oejeon-Naejeon(外殿-內殿), of Chosun dynasty palace. The planning principle of Sam-Jo at government office, Dongheon(東軒) territory for rule administration corresponds to Chijo(治朝) with a local governor who is the ruler, as for the Naea(內衙) territory which a family of him and he lives in, it is corresponded to Yeonjo(燕朝), and in the job space of Ajeon(衙前), it is corresponded to Oejo(外朝). As for the application of the inside and outside principle of provincial government office, Dongheon is corresponded to Oejeon and Naea to Naejeon. A compositive and an approach axis of government office in Chungchong-do is correspond with Dongheon in the center, and these axes form an central axis and an entry space of government office included Oesammun(外三門) Naesammun(內三門) Dongheon or Naea. Because an essential performance of provincial government office is provincial administration, the layout configuration of government office is a function, which is an expression of an official institution.
