A concept of 'digital' is changing a living pattern of moderners, with having influence on the whole life of modern society. The purpose of this study is arrange the frame of conformity to the 'fashion as culture' by considering the social and cultural phenomena being shown in relation to digital, which is a concept being watched most for the 21st century and by trying to analyze a tendency of digital culture being shown in the modernly fashion design based on this. The digital culture, which is a concept of generalizing the phenomena of interactional changes in the sub-structure being derived by digital technology, is being shown as a tendency of fusionization and globalization, and due to this, the culture of digital nomads is being formed. On the other hand, a tendency of amenity caused by the reaction against the coldly digital technology, is forming one axis of digital culture. As the culture, which experiences the process of a change by digital technology, is reflected even on the fashion, the fusion of technology and the human body, brought about the appearance and the development of the artificial body, by allowing the wearable computer to be introduced to fashion and by being connected directly to the body. This means the expansion of range for fashion. The destruction of a border between space and space, is making an opportunity of forming another ego inside the cyber space, with bringing about the mixed loading between the cyber space and the real space. As the border between the cyber space and the real space is being collapsed, the space of newly self-realization is being created. The collapse of gender is being shown as the pursuit of gender, which is a nomadic concept of not giving priority to anywhere of male gender and female gender. The tendency of sensitive design introduced the sports look as the largely fashion trend. Fascinated with Zen thoughts is leading to a response to the swiftly and coldly social conditions caused by machine. The digital culture by digital technology and the fashion tendency being shown by its influence, meet the needs of self-realization and self-expansion for a human being, and satisfy the needs for the expression of self-identity for a human being, and enable the search for introspection about inner existence inside the self.
This study has carried out scanning tests in order to figure out the features of scanning search by sex of space users, with the result of which the validity of data has been estimated. In this research, the scanning patterns were set up for verifying the typology of scanning paths and then the reason for determining scanning paths and the validity of estimation method were reviewed. Since the observation features depends on sex, the analysis of visual activities for acquiring any information in a space will reveal the intention and purpose of space users. The findings by analyzing the features of scanning pattern by sex which were found at the determination of scanning patterns can be defined as the followings. First, for estimating the process of space-information search, the movement distance at each point of continuative-observation data from the angle of eye-movement has been extracted, on the ground of which the fixation and movement of eye have been defined for the establishment of scanning-cut characteristics. Second, the scanning times were estimated for the extraction of effective observation data that would be used for comparative analysis, which showed that men had more data (3,398.2/64.4%) than women (2,998.2/55.6%). This enables the acknowledgment that the scanning cut of men was relatively less, which indicates that men will acquire more information on space than women in the process of observing any space. Third, men's scanning times (58.0 times/2.02 seconds) were less than those of women (71.9 times/1.39 seconds) while the scanning time of the former was longer than that of the latter, which shows the feature that it takes longer for men than women in scanning while the scanning times of the former is less than those of the latter. Fourth, the observation features can be determined that the combination of this result with the predominance character by sex for a general viewpoint to be employed indicates that while men employ mixed-scanning for observation activities to acquire space-information spending for longer time, women, by concentrated-scanning, focus on a single point for shorter time or stay at one location for a considerably long time for space-information acquirement.

High strength concrete is not only vulnerable to the occurrence of spalling which generates the loss of cross-section in concrete structures but produces faster degradation in its mechanical properties than normal strength concrete in the event of fire. This study aims to evaluate fire resistance of high strength segment concrete with PET fibers mixed to prevent spalling under ISO834 (2hr) and RABT fire curve. As results, the samples without PET fibers show the concrete loss up to the depth of about 8 cm and 9.5 cm from the surface exposed to fire under ISO834 and RABT fire curve respectively. The samples mixed with PET fiber of 0.1% show no spalling under ISO834 fire curve and the spalled thickness of 6.5 cm under RABT fire curve after the fire tests. Finally, the sample mixed with PET fiber of 0.2% shows no spalling under RABT fire curve. The results indicate that the suitable amounts of PET fiber for securing fire resistance performance of this high strength segment concrete are 0.1% under ISO834 fire curve and 0.2% under RABT fire curve. However, even though spalling does not occur, it is necessary to repair the deterioration of concrete up to 4 cm from the surface exposed to fire after fire.

The risk assessment is essential for tunnel design in order to minimize risks associated with uncertainty about geological conditions and tunneling method. This paper provides a comparative risk analysis of a large single bore TBM driven tunnel against sequentially excavated NATM tunnel for a mixed-face large-diameter urban tunnel project near or under a river. The focus of this assessment is on the risks associated with the tunnel excavation methods, in particular whether a TBM or NATM presents more or less risk to achieve the planned excavation duration and bring the project within the estimated bid price. First, the impacts and risks to tunnel construction under each method were discussed, and the risks were scored and ranked in the order of perceived severity and likelihood. Finally, the assessment from a risk based perspective was conducted to decide which alternate tunneling method is more likely to deliver the project with the least time and cost. It is very important to note that this study is only applied to this tunnel project with specific geological conditions and other contract requirements.
The purpose of this study was to analyze the type of extended-balcony floor plan which has been reflected as a various forms after making amendment to the apartment extended-balcony legislation on December 2005 and to understand the design tendency of housing unit plan and the characteristic of living space planning by the type of size(pyeong) and extension. The objects of analysis and the plans are 333 example(235 of $84m^2$, 98 of $59m^2$) from the LH corporation competition. The design tendency of balcony space after extension is as follows; First, a type of extension for simple area to increase the area of room adjacent to balcony through balcony extension. Second, a type of functional reinforcement for private room to separate the mixed function followed by strengthening the individual function of the private room. Third, a type of ${\alpha}$-room to play new functions as hobby room, study room, soho-type room with working from home by extending balcony. Fourth, a integrated type to increase flexible efficiency of bed room, living room and kitchen by integrating extended-balcony from the flexible plan. Along with the evaluation of living style through user's environment-behavior research and the counterplan for evacuation space, indoor thermal environment and space for fulfilling the original function of balcony should be proposed in the future study.

The Educational Cultural Center for Students is a new mixed-cultural space which made around 1997 for students' education of humanism and talent with the 7th revision of educational course. This Educational Cultural Center for Students is different to the existing one because the subject of the culture is students who make creation and performance by themselves while the former ones were for seeing, hearing and feeling things. There are seven Educational Cultural Center for Students all over the country and will be built more in the future. Comparing to the former Educational Cultural Centers for Students, functional rooms in the Educational Cultural Centers for Students are an outdoor performance room, a large performance room, a small performance room of performance facility, a gallery of display facility, a gymnasium, a swimming pool, a fitness room, a table-tennis room of physical facility, a library and a reading room of a book facility, and a group room, a computer room, a singing room, a billiard room, an art room, a musical room, a dancing room, a manner room, a playing room, a cultural lecture room and a seminar room of a interest-activity facility. The result of analyzing the usage frequency is that a performance room has the highest frequency and a display room, a musical room, a music appreciation room and a physical room follow the frequency order. But this frequency does not fit for all area. By place and social situations, the frequency and space organization may be changed.

Today's Software Systems are becoming bigger, larger and more complex than ever before. To develop largerscale projects, it is required that many experts of different fields participate and cooperate in the same project. So, it is an applied area of CSCW(Computer Supported Cooperative Works} that centers around methodologies and tools that enable cooperative works by geographically distributed people engaged in all aspects of product development. In this paper, we designed a multi-user cooperative works platform, SPACE(Software Platform for distributed Application sharing under Cooperative Environment} as a infrastructure that support to CSCW based system development for telecommunication and information system. SPACE has a fully distributed architecture under Windows 95 environment, has an application sharing mechanism enabling collaborative use of mteractive application adapt to a mixed GUI sharing technology which capture GUI and screen information, and also, an event sharing technology that has a replicated architecture.
After the rapid growth of economics in South Korea 1960'1, the number of workers in the whole land in-creased day after day along with the growth of industry. As the growth of the third industry occurred quite rapid-ly, the rate of office workers went up high. Accordingly the business office has been changed the primary work-ing space and recognized the main space as much as the living space. As a result of conceptual change about working place, the business office has an important ef-fect on worker's liberal and psychological environment. In order to provide the office workers with the office work-ers with the suitable and convenient working environ-ment, Socio-psychological factors were first considered at the first stage of construction planning. In this paper, I would understand both how office workers take up their attitudes of Socio-psychological point according to the office type and what they claim for their office environment. This understanding offers us fundamental data in office plan. This paper starting from this purpose got the following conclusions. *Office workers are violated their hearing privacies rather than their visual privacies. They are dissatisfied with ensuring their own spaces and satisfied with their nature of domain. *In the feeling of satisfaction by office type, they are on the whole satisfied with their hearing privacies, their visual privacies, their own space, and the nature of do-main in the closed type and mixed type offices. In open type offices, their visual privacy is often violated. *In the property by individual, men feel more violated their hearing privacies than women. In the personal spa-se and domain, women are less stabilized psycholo-gically than men. *The analysis of the attitude by position, a man of po-sition is more violated his hearing privacy and does not understand each other. The common run of workers are violated their visual privacies and the nature of separa-tion.

The design process of blended inlet body (BIB) for the preliminary design of a near-space high supersonic unmanned aerial vehicle (HSUAV) is presented. The mass flow rate and cowl area of inlet at a design point are obtained according to the cruise condition of the HSUAV. A mixed-compression axisymmetric supersonic inlet section with a fixed geometry reasonably matching the high supersonic cruise state is created by using the inviscid theory of aerodynamics. The inlet section is optimized and used as a baseline section for the BIB design. Three BIB concepts for the HSUAV are proposed, and their internal aerodynamic characteristics of inlet are evaluated using Euler computational fluid dynamics (Euler CFD) solver. The preferred concept is identified, in which the straight leading edge of the baseline HSUAV configuration is modified into the convex leading edge to accommodate the inlet and meet the requirements of the cowl area to capture the sufficient air flow. The total recovery of inlet for the preferred BIB concept and the aerodynamic characteristics of the modified HSUAV configuration are verified using Navier-Stokes computational fluid dynamics (NS CFD) solver. The validation indicates that the preferred BIB concept can meet both the requirements of the inlet and aerodynamic performance of the HSUAV.

Titanium and its alloys are useful for implant materials. In this study, porous Ti-Nb-Zr biomaterials were successfully synthesized by powder metallurgy using a $NH_4HCO_3$ as space holder and $TiH_2$ as foaming agent. Consolidation of powder was accomplished by spark plasma sintering process(SPS) at $850^{\circ}C$ under 30 MPa condition. The effect of high energy milling time on pore size and distribution in Ti-Nb-Zr alloys with space holder($NH_4HCO_3$) was investigated by optical microscope(OM), scanning electron microscope(SEM) & energy dispersive spectroscopy(EDS) and X-ray diffraction(XRD). Microstructure observation revealed that, a lot of pores were uniformly distributed in the Ti-Nb-Zr alloys as size of about $30-100{\mu}m$ using mixed powder and milled powders. In addition, the pore ratio was found to be about 5-20% by image analysis, using an image analyzer(Image Pro Plus). Furthermore, the physical properties of specimens were improved with increasing milling time as results of hardness, relative density, compressive strength and Young's modulus. Particularly Young's modulus of the sintered alloy using 4h milled powder reached 52 GPa which is similar to bone elastic modulus.
