The environmental considerations should be taken into full consideration in order to make the use of ground space as comfort and efficient as that of ground space. The visual environmental factors which provide visual informations in underground spaces where the environmental information can be acquired only by the surroundings expand their role as affordance for wayfinding. This study focuses on the visual performance evaluation of wayfinding factors on the subway transfer station platform and aisle as major space for movement in four subway transfe stations and analyzes the material, pattern, color, and lighting provided by the visual environment in underground space as directional marked label, regional differentiation and sign system. The results of this study comes are as follows. First, As to the directional marked label at the subway platform and transfer aisle, following patterns are colors, finishing materials and lighting for the sake of safety and convenience, And regional differentiation, following colors are patterns for the space division. Finally sign system which practically provides the most information, however, it is most insufficient to be a space-preception element. Second, According to the type of platform structures, such as an island platform and a separate platform, the main areas of and necessity for the space-perception elements may bring about changes. Third, these four stations that has been analyzed for this study, lighting, compared with color, finishing material and pattern, has been highly insufficient to be a perception element.

Commercial space, the types of which have been increasingly various and changing rapidly, has been generating new marketing concepts for space. Especially as the environmentally friendly lifestyle spreads around, the component of natural landscape such as plant, stone, or water has been used as an important part in space design, freshly imprinting the brand image beyond the idea of simple interior property. By combining commercial space design with 'the component of the natural landscape', we can improve the brand image, create the newness in the space, lead customers to stay longer in the space, and reinforce the decorative effect. The parts of the commercial space to which we can apply the element of natural landscape are facades, walls, floors, and show windows. Various examples of real application are found according to the areas of business and goods displayed. This thesis attempts to maximize the effect of commercial space by examining and analyzing various instances of space and provide the ways of applying the space that contains an aesthetic value. For the research, 60 articles, theses, reports that have the keyword related to interior landscape and marketing strategy in commercial space were used as references. From the references, 70 cases were selected and analyzed to find landscape application patterns. Also, 4 store cases that landscape application have been the key to their success were selected for the survey. In doing this, I presented the readers with the packaging technique which improves brand image, the effect of stage direction which helps sensitive communication with users, the application as interior structure and the effect of an object that is useful to aesthetic effect in the commercial space. Finally, I endeavored to provide possible problems to be produced when applying the natural element in the commercial space and matters to be attended to in the management.

A public library is changing into a place where people can freely acquire and make use of information in digital environment with the basic ideology of publicity. In spite of such changes, multimedia center is still biased with the function of computer room to use PC and is not used actively by many users. This study can be summarized and concluded as follows and spatial characteristics of digital data room of public library can make use of space planning elements by aspects as an analysis tool. First, designed characteristics focusing too much on the possession of seats for reading digital data. Therefore, spatial planning for users to choose necessary facilities according to the data they wish to read and type of users is needed. Second, interior tone of multimedia center is applied with identical color for all floors, walls, and ceilings, to create sense of unification. However, due to the arrangement of similar colors, while using identical brightness and chroma, some users felt difficult to realize shape or depth in space. It is more appropriate to apply distinctive color plan according to the characteristic of the data or space region, in order to create pleasant digital environment for visually weaker people or elderly. Third, psychological or technical factors of multimedia center is not sufficiently applied in space planning elements for users. In order for various digital service of public library to be technically implemented, it is necessary to organize open space by expanding the size of multimedia center to utilize high-tech facilities.

Several factors are discussed that should be considered in measuring thermal conductivity of rock cores with a PEDB (potable electronic divided bar) system, which is relatively accurate and easy to operate, and can measure the thermal conductivity of rock cores for various diameters. Then the system is applied to measure thermal conductivity of 70 rock cores from Ulleung Island. Air temperature affects most on the thermal conductivity measurements, so that it is very important to minimize the temperature change during the measurement. Other factors such as the temperature of heat source, averaging time window on the thermal conductivity measurements do not affect much compared to air temperature. Slightly higher thermal conductivity is measured when using the thermal contact paste between the sample and heat source or heat sink. Especially, rock cores with irregular surface showed bigger difference. Repeatability showed less than ${\pm}0.3%$ for standard samples and less than ${\pm}4%$ for rock samples, respectively, when the room temperature changes within $1^{\circ}C$ during the measurements. Thermal conductivity of the rock cores from Ulleung Island roughly increases as depth increases but does not show any dependency on the rock types.

Recently, as human-centered design and humanization of space accelerates, the concept of physical space is changing to user-centered space. In particular, in the case of exhibition space to utilize digital media, visitors' actively experiencing exhibits and participating exhibition are regarded as an important factor, thus affordance design serves as a crucial factor to afford satisfaction with exhibition space to the visitors. Accordingly, the study is to understand the concept of the affordance and the digital media exhibition environment and to analyze the preference for each affordance design factor in the digital exhibition environment. The survey is conducted to people in the twenties who inhabit Seoul and the metropolitan area, familiar with the digital media. The results of the survey show that the most important role of the digital media in the exhibition environment is to create the atmosphere for concentration and complexity is the most preferable among interactivity, network ability and complexity, the feature of the digital media. Additionally, the results reveal that cognitive affordance presenting the feature of design to help the user when he/she want to know something is the most preferable among sensory affordance, physical affordance, cognitive affordance and functional affordance and as the time exposed to the digital media increases the importance of the affordance design is high. As the digital environment is common now in many fields, it will be regarded as a crucial factor to the visitors of an exhibit hall from now on whether affordance design is used.

The mechanical behavior of a micropile due to horizontal load has not yet clearly identified in Korea. It has generally estimated from that of a traditional pile because there is no standard method even though it has shorter length. To tell the truth, its behavior is very different from a traditional pile's. Specifically, it is general fact that horizontal resistance of earth is one of the main factors to control the mechanical behavior of micropile. To this reason, a laboratory model has been made in this study to estimate the behavior of a micropile which loaded increasingly horizontally. The laboratory model has been designed to estimate both the behavior of load to displacement and skin friction to displacement. And the analysis of the latter was compared with the solution of strain wedge model. In the end, it was proved that the mechanical behavior of a micropile should be estimated from considering the horizontal resistance of earth.

In recent years, because of the development of ubiquitous technology in healthcare research is actively progress. Especially, healthcare service area is change to home for the elderly or patients from hospital. The technology to identify residents in a home is crucial for smart home application services. However, existing researches for resident identification have several problems. In this case, residents are needed to attach of various sensors on their body. Also relating private life, it is difficult to apply to resident's environment. In this paper, we used constraint-free sensor and unconscious sensor to solve these problems and we limited using of sensor and indoor environment in the way of working economical price systems. The way of multi-resident identification using only these limited sensors, we selected elements of personal identifications and suggested the methods in giving the weight to apply these elements to systems. And we designed the SABA mechanism to tract their location and identify the residents. It mechanism can distinguish residents through the sensors located each space and can finally identify them by using the records of their behaviors occurred before. And we applied the mechanism designed for applications to approve this location tracking system. We verified to the location tracking system performance according to the scenario.
