This study emphasizes users' participation, a living-transforming visuality, as users have appeared to be a central element of landscape design but ignored before. Also this study tries to propose meaning of extended visuality in contemporary landscape design on the basis of visual criticism on simple perception-and contemplations convention-based landscape design. For these purposes, this study reviews characteristics of visual changes appeared in modern reductionist paintings. In other words, arts can be interpreted in polysemous ways through bodies' experience. Deconstructive concepts derived from the theoretical reviews can be categorized into three including the participation of the users' bodies from a contemplative point of view, textuality and intertextuality, and experiences from works. Those concepts were used to criticize the previous discourse on landscape designs and to analyze various issues in the theories, themes and techniques in contemporary landscape design. The significance of the expanded visuality in contemporary landscape design is that it brings the users' voluntary participation. This structure can serve as a tool to obtain the users' perceptive effects. At the same time, it can be regarded as a process of establishing the relationships between the users and the works. Thus emphasis is placed not only on the influences of the effects structure of the works themselves, but also on the many different dimensions related to the users' bodies. It implies that the meaning of design is not determined by the designer but a product resulted from the voluntary relationships between users and works. These findings lead to ambiguous distinctions between arts everyday life, and eventually to the end of the concepts of formative dichotomous aesthetics and their effectiveness. Finding of this study call for not only redefining the space where landscape design is created and communicated, but also reconsidering the concepts of landscape design and its ontological meanings.

SAFRS is the system designed to reproduce the harmonic sound into the space according to the environmental factors. Here the harmonic sound means the sound which judged by the subjective tests, and the methods were suggested in the former studies. In this research, SAFRS was applied into the Square of D University to evaluate and verify the effectiveness of the system and a few evaluations were carried out as follows; 1) sound perception, frequency, volume and harmony with the space, 2) images of the square and acoustic environment and 3) acoustic environment with existing sounds, fountain sound, produced sound by SAFRS, and both of them respectively. The results can be summarized as follows; 1) According to the evaluation on acoustic environment, no relationships were shown between the cognition of sounds produced by SAFRS and the frequency or volume, but inverse proportion was shown between the volume and special harmony. 2) As the result of image evaluation. the relationship between space and sound image was shown proportional only except the evaluation on main road at night time, it means that the sound proposal with the visual contents matching with the sounds would be more effective than the proposal of sound only. 3) Results of evaluation on acoustic environment showed that the cognition effect at night time was shown higher than that of day time when only the acoustic element was given and the effect was increased when the visual elements matches with the acoustic elements if both of them were given. It confirmed the harmony between visual and acoustic elements was very important.

This study discusses the architectural space's phenomenology, focusing on the physical environment and psychological behavior. Kim, Ju-Tae House, which is divided by special relationship, was analyzed by method of constructing space, and behavioral meaning with the perspective of visual structure. Kim, Ju-Tae House was constructed in a clear way by reflecting the users social, and cultural relationship. It has a relational and independent territories by physically surrounding Chae and wall. Each independent limited space is suggesting the space being opened by accessing the space stage by stage. This method of constructing the space makes the user aware of the relative difference from the induced space experience, and recognize the incremental strong isolation. Between the yard, which is located in the center of the house, forms a three-dimensional layer between Sarangchae and Anchae, emphasizing the spacial depth. The physical space is relatively small but because of the environmental conditions, such as the positioning of the observer's perspective, short cycle reorientation, and overlapped layer, it is recognized as far or deep compared to the actual size. This is the relative method as a visual perspective that is intended, and is understood as an active element that induces the psychological attitude by the recognized environment affordability of the user.

Recently, brick walls are being widely introduced in rural areas. Walls are a very important design element of space. However, most brick wall works do not consider the human psychological characteristics. The purpose of this study was to investigate psychological characteristics on brick wall bonds such as the stack bond, running bond, english bond, flemish bond, america bond. The results of the research can be summarized as follows: 1)There is no statistical difference of psychological evaluation results among student groups using the semantic differential scale method using 10 adjectives. 2)Stack bonds have an uninspiring, artificial, simple, restful, boring and ordered psychological characteristic. Running bonds have an uninspiring, restful and ordered psychological characteristic. America bonds have a unique and modernistic psychological characteristic. English bonds have a unique, modernistic, complex and chaotic psychological characteristic. Flemish bonds have no critical psychological characteristics. 3)The running bond earned the highest score in preference, while the stack bond scored the lowest. Employment of brick wall bonds on this study was not highly preferred, hence it is necessary to develop a new brick wall bond design. 4)In conclusion, the proper selection of brick wall bonds is very important and we should consider human psychological characteristics in the design of rural areas.

The purpose of this study was to investigate how subcategories of the country-specific-advantage (CSA), which has been discussed in previous studies, affect the buying intention of Korean rice. After reviewing existing studies and examining research models based on them, a research model was verified by questionnaires and statistical analysis. The results of the surveys and statistical analyses reveal that the CSA factors presented in previous studies can also be applied in the context of Korean rice products. The results show that environmental resource, cultural resource and visual element factors influenced the buying intention through perceived quality. In addition, cultural resource perception factors have a direct effect on buying intention. This is consistent with previous studies showing that emotional communication approaches are ineffective for products that are perceived to have functional characteristics. Based on the results of this study, it was confirmed that CSA factors are suitable for the product and export target area. Strategic implications are suggested in that it is necessary to build marketing strategies to improve the perceived quality by the four factors. The theoretical implications are as follows. The sub-factors that constitute COI may have a negative effect and a positive effect; thus, it is necessary to utilize CSA when considering the product and country characteristics. The CSA factors revealed in previous studies are also significant in other regions and products. Finally, the theoretical implication is that consumers use CSA as a clue to evaluate quality.

Based on numerical and experimental methods, a systematic structural evaluation of a steel natatorium in service was carried out in detail in this paper. Planning of inspection tasks was proposed firstly according to some national codes in China in order to obtain the economic and reliable results. The field visual inspections and static computation were conducted in turn under in-service environmental conditions. Further a three-dimensional finite element model was developed according to its factual geometry properties obtained from the field inspection. An analytical modal analysis was performed to provide the analytical modal properties. The field vibration tests on the natatorium were conducted and then two different system identification methods were used to obtain the dynamic characteristics of the natatorium. A good correlation was achieved in results obtained from the two system identification methods and the finite element method (FEM). The numerical and experimental results demonstrated that the main structure of the natatorium in its present status is safe and it still satisfies the demand of the national codes in China. But the roof system such as purlines and skeletons must be removed and rebuilt completely. Moreover the system identification results showed that field vibration test is sufficient to identify the reliable dynamic properties of the natatorium. The constructive suggestion on structural evaluation of the natatorium is that periodic assessment work must be maintained to ensure the natatorium's safety in the future.

For the office work environmental design, the importance of the design management is increased to improve operation efficiency as well as the aesthetic environmental implementation of the function today. Lighting is a required element ineffective operation environment. It has become more important for the aesthetic, economic, and practical reasons, to consider the luminous environment and the lighting of visual tasks separately. When the brightness is insufficient, productivity deteriorates, and the layout of the lighting located by mistake causes the fatigue of eyes. Productivity rises to office in a large number of studies so as satisfaction is low in general in the dark office, and to be bright. Therefore the purpose of this research is to suggest the right direction of lighting design of office building area. 11newly renovated office buildings are selected for this luminous environment research. We could conclusions as following through this research. First, it was planned brighter than the recommended lighting level in the most space. It shows that the accurate lighting design criteria is needed in order to achieve proper lighting environment. Second, the application of the LED lighting fixtures is continuously increased in the recent office lighting environment. It is explained that it is applied for reasons of the electrical energy reduction and the maintenance efficiency with the long life time. Third, the consideration of the lighting plan for the difference of working types is not enough. with various communication configuration through an independent plan, and the effective lighting plan that appropriateness preparation design and energy saving area vailable must be applied. Fourth, the lighting environment of the lobby needs a specialized lighting plan as are presentative space of the building.
