The number of shared offices has increased and changed within the flow of the era into various forms in recent days. Co-working spaces and related shared space businesses are growing fast, keeping pace with the trend recently. It is confirmed that the need of spaces grew 180% since 2015 to 2017. Most of the shared offices in Seoul are placed in Gangnam circle, it is verified that shared office is providing work, space, and community by visiting cases of foreign companies, domestic companies, local companies. Meanwhile, shared space can be categorized into serviced office, co-working space, virtual office, and daily office. It is to consider various target levels by leasing service or the difference of costs. It is divided into forms of dispersion, circulation, and concentration and is planned to increase the utilization of communities' traffic according to the allocation of shared office. The business is conducted network-centered. During the process of communication, members can get chances to exchange and build communities. They are making business ecosystem which they can coexist and grow together. Shared offices have a view of a solution to empty rooms and will last for a while, and it is expected that co-working system be settled as office space and giving people sense of belonging on their workspace.

During fabrication process for the large space optical surfaces, the traditional bound abrasive grinding with bronze bond cupped diamond wheel tools leaves the machine marks and the subsurface damage to be removed by subsequent loose abrasive lapping. We explored a new grinding technique for efficient quantitative control of precision CNC grinding for space optics materials such as Zerodur. The facility used is a NANOFORM-600 diamond turning machine with a custom grinding module and a range of resin bond diamond tools. The machining parameters such as grit number, tool rotation speed, work-piece rotation speed, depth of cut and feed rate were altered while grinding the work-piece surfaces of 20-100 mm in diameter. The input grinding variables and the resulting surface quality data were used to build grinding prediction models using empirical and multi-variable regression analysis methods. The effectiveness of the grinding prediction model was then examined by running a series of precision CNC grinding operation with a set of controlled input variables and predicted output surface quality indicators. The experiment details, the results and implications are presented.

Purposes of this study, summoning thoughts and activities of Toynbee Hall of the UK and Hull House of the US held in between the end of 19C and the early 20C, are two folded: first, it is to examine the momentum and aims for which 'social' work was progressively established at that time; second, it is to look for implications for today's social work practice through understanding their characteristic activities and the context in which 'social' work was devised as an alternative in the two nations. The study method mainly relies on literature review, but further goes on to analyze the spirit of the age when settlement house was constructed as a welfare space and activities, leadership demonstrated in there, and to draw meanings for today, in terms of three dimensions: aim and location, professionality and education, and social action. Some of useful findings are: first, the COS and settlement house need to be considered in a continuum of socially responsive remedies against poverty and social work practice was developed in the process of 'suggestion-performance-critique-alternative suggestion-emergence of social work', rather than contrasting the two as opposite roots of social work practice. Second, settlement house was a socially constructed welfare space that contained intersectional dynamics of class, gender, personal vs. social, private vs. public, surrounding poverty issue. Third, besides differences between the two settlements, both purported for public goods and well-being and tried to realize the 'social' in that society. Lastly, this study explored historical meanings of settlement house as the welfare space with critical questions and discussed implications for social work practice today.

There is an increasing trend each year in the number of subway users due to increase in the traffic volume. As the number of train service has risen, the subway drivers are given heavy work and from the same, are put at risk of mental health deterioration due to stress. As this is directly connected to safety, there is an urgent need for improvement of the situation. Therefore, as a way to appropriately relieve such stress, resting space where mental and physical energy can be recharged is necessary. Thus, this research conducted a survey of demand with subway drivers as subjects in order to provide resting space that can offer healthy rest and increase work effectiveness. 50 subway drivers were the subjects of this survey. As a result of analyzing the contents of the survey, environmental satisfaction was shown to be the lowest compared to psychological and morphological satisfaction. In the case of sleeping room, they wanted more comfortable and individual space. And the waiting room had the highest rate of usage frequency. The storage space was where the subway drivers showed the strongest attachment and was shown to be the only personal space. Most were shown to be satisfied with the outdoor space, but it had the lowest usage frequency. In addition, it is nessasery customized storage cabinet designed for subway drivers should be produced, which can effectively arrange the limited space. I hope that these direction of improvement can increase the healthy rest and work effectiveness of the locomotive engineers as it is directly being connected to the health and safety of the citizens.

The detection of an underwater work space boundary is very important when an underwater construction is carried out using seabed type underwater equipment, such as underwater machines for rubble mound leveling, because it can induce industrial disasters. Therefore, divers are needed to mark the underwater work space boundary. A nylon rope is used to improve the convenience during an underwater diver's work. The results showed that the work space boundary can be detected using a sonar system. Using these results, an efficient method to detect the underwater work space boundary can be obtained when an underwater construction is carried out using seabed type underwater equipment.

As computer system and information/communication technology develop rapidly, nowadays CSCW(Computer Supported Collaborative Work) system appears, through which it is available to work on virtual space without any restriction of time and place. Most of Un systems depend on a special network and groupware. The systems of graphics and CAD are not so many because they are characterized by Hardware and application software. In this paper, we propose a web-based collaborative CAD system which can be jointly worked on Internet WWW being independent from any platforms. It can generate and handle objects easily using lava 3D, and it can transmit, print, and store them. The interactive work for designing objects can be also carried out through dialling with each other. This system is executed in the environment of Client/server. Clients connect to the server through lava applet on WWW. The server is implemented by lava application, and it consists of three components : connection manager which controls the contact to users, work manager which keeps viewing in concurrency and provides virtual work space sharing with others, and solid modeler which generates 3D object.

In this research work, we introduce and investigate four innovative types of soft spaces, pushing the boundaries of traditional spatial concepts. These new types of soft spaces are named as soft T_b space, soft T^#_b space, soft T^##_b space and soft_αT^#_b space. Through rigorous analysis and experimentation, we uncover and propose distinct characteristics that define and differentiate these spaces. In this research work, we have established that every soft $T_{\frac{1}{2}}$ space is a soft _αT^#_b space, every soft T_b space is a soft _αT^#_b space, every soft T^#_b space is a soft _αT^#_b space, every soft T_b space is a soft T^#_b space, every soft T^#_b space is a soft T^##_b space, every soft $T_{\frac{1}{2}}$ space is a soft ^#T_b space and every soft T_b space is a soft #T_b space.

This study places a great emphasis on the approaches to the space environment we inhabit, which I hope will contribute to generating a number of creative possibilities. Looking into 'site-specificity' which is characteristic by public art in public space method based on Daniel Buren's works 'in situ', this study analyze the relationship between the public space and works of art as a perspective of public art. The characteristics of his 'in situ' works that intervened works exist as space consisting of serial factors not simply art-object, and they suggest 'site Is a work'. The case study of Daniel Buren's public art project represented the results, the site marketing and serves as a guideline for the future of true Art/Space experiments. This study verifies the need for the arts and the space to work together in order to develop more creative and conceptual approaches to innovation and presentation. This cooperation is the continuation of space design by other means.

A study of light in Kahn's architecture must be significance as a work in building new architectural space and a new foundation for architecture, as well as clarification of the uniqueness of Kahn's architectural space and search for its significance. In addition, the study provides a greater comprehension of an the concept of Kahn's architecture by clarifying the degree of association of light into other concepts of architecture. Therefore, this study attempts to examine Louis I. Kahn's statement, sketch and work. His sketch along with the characteristics of the technique how to present it also enables comprehension of other aspects of architecture as a means to revive architecture. Khan's use of light enabled the evolution of primarily two types 'specular surface' and 'unique opening part' by associating them with the need to diminish glaringness. Each of these types has been evolved individually and is indicative of a concept of light that can be largely divided into ' object's light ' and ' space's light ' Object's light refers to a type in which the formative significance of structural part and different directions of light coexist, and its formative characteristics play a role that differentiate places within space. Space's light is present on wall spaces that limit space and exhibits its distinguished role differentiating places within space in the form of 'expression'.
