Increased internet use under a ubiquitous environment may be called as a great human information space revolution followed by Industrial Revolution. This revolution is exerting its significant influence over all the industry as a whole with speed faster than that of any other times. Along with this trend, if furniture design field that leads living culture should fail to jump on this main stream without noticing it, it may be reduced to a unpopular field some day without any sign of recovery. Under this background, this study is intended to recognize a goal aiming at understanding our rapidly changing living environment and leading our way positively. Currently, our surrounding living environment is immersed in computers here and there and Mark Weiser once defined a system that moves in advance before an action as ubiquitous computing and in this respect, I am going to observe a detailed transformation process of space. First nature of the space may be defined as atoms, a physical space equivalent to a spatial element and Bits space that is untouchable is usually called as 2nd space and a combination of atoms and Bits is an intelligent space - 3rd space - that can be intelligible without touching it and finally, this space is called as a ubiquitous space. This spatial transformation is developed by several changes of living environment and we may call it as living trend or interior design trend. Transformation in terms of social perspective, space structural perspective and digital technique perspective may be enumerated. These transformations were surveyed based on its contents being implemented at a future housing exhibition hosted by 5 construction companies along with fusion of information furniture and furniture depending on each housing space. In conclusion, it could be realized that most of the companies were decorating future space by implementing ubiquitous environment as a success factor of future housing market. It may be meaningful to note once again that under an interior environment, a fusion of furniture and information furniture is required considering interior trend elements.

Background: Significant technological development and changes happened in the tractor industries. Contrariwise, the test procedures of the major standard development organizations (SDO's) remained unchanged or with a little modification over the years, demanding new tractor test standards or improvement of existing ones for tractor performance, safety, and comfort. Purpose: This study focuses on reviewing the research trends regarding performance, safety and comfort evaluation of agricultural tractors. Based on this review, few recommendations were proposed to revise or improve the current test standards. Review: Tractor power take-off power test using the DC electric dynamometer reduced human error in the testing process and increased the accuracy of the test results. GPS signals were used to determine acceleration and converted into torque. High capacity double extended octagonal ring dynamometer has been designed to measure drawbar forces. Numerical optimization methodology has been used to design three-point hitch. Numerous technologies, driving strategies, and transmission characteristics are being considered for reducing emissions of gaseous and particulate pollutants. Engine emission control technology standards need to be revised to meet the exhaust regulations for agricultural tractors. Finite Element Analysis (FEA) program has been used to design Roll-Over Protective Structures (ROPS). Program and methodology has been presented for testing tractor brake systems. Whole-body vibration emission levels have been found to be very dependent upon the nature of field operation performed, and the test track techniques required development/adaptation to improve their suitability during standardized assessment. Emphasizes should be given to improve visibility and thermal environment inside the cab for tractor operator. Tractors need to be evaluated under electromagnetic compatibility test conditions due to large growing of electronic devices. Research trends reviewed in this paper can be considered for possible revision or improvement of tractor performance, safety, and comfort test standards.

This Study is a thesis presenting handicrafty and decorative textile design as well as sensual fashion design through the works of Gustav Klimt. The result is as below; The formative qualities in the works of Klimt could be featured as decorativeness, sensuality and symbolism. First, the decorative inclination is prominent in the portrait and the effect is maximized with the golden mosaic shape expressed on the dress and the background influenced by the Byzantine. Second, the sensuality could be recognized directly from the women's pose or facial expression in the works of Klimt, otherwise appeared on the refined expression showed on the portraits of noble lady Third, to surpass the reality, Klimt preferred the symbolic expression, which can be shown on the patterns in the works addressing the themes such as the legends and myths, or figures of men and women expressed with the image of an abstract features of membrum. The development of the textile design is as fellowed. First, it analyzes and reconstitutes the formativeness and the element of design in the works of Klimt by the flow of the form factor. Second. it makes a pattern of a single nature through perception, analysis, description and drawing and expresses with realization of the characteristics of Klimt. Focusing on the handicrafts and decorativeness out of the latest trends and making the most use of the sensuality, the designed textiles were completed by the handicrafty techniques, used in the fashion design and completed as the design of sensual images. The textile development aims at minimizing the limit of design that can be caused by the absence of silhouette and detail, expanding the range of its creativity of fashion designs and creating fashion design high value-added.

현재까지 전기비저항 탐사자료의 해석은 대부분 지하구조가 1차원 또는 2차원으로 가정하는데 근간을 두고 있다. 그러나, 국내와 같이 지질구조가 복잡하며 지형의 기복이 심한 경우, 이와 같은 가정을 사용은 전기비저항 탐사자료의 해석에 오류를 야기할 가능성이 높다. 본 연구에서는 3차원적으로 복잡하게 변화하는 지하구조 및 지형의 기복에 의한 지형효과를 정확히 계산할 수 있는 유한요소법에 의한 3차원 전기비저항 모델링 알고리듬을 근간으로 하는 역산 알고리듬을 개발하였다. 이 알고리듬은 ACB(Active Constraint Balancing)법을 채용함으로써 역산의 분해능 향상을 기하였다. 간단한 3차원 지하구조 및 지형기복에 대한 수치모형 실험결과 지표의 불규칙한 기복을 포함하여 역산을 수행함으로써 정확한 지하구조 영상을 획득할 수 있음을 보였으며, 국내의 교량건설 예정부지에서 수행된 격자망을 이룬 전기비저항 탐사자료에 대한 3차원 역산 결과 매우 신뢰도 높은 지하구조에 대한 영상을 도출할 수 있었다.

This study is a fundamental research which suggests some standards that can be used in selecting some advanced materials to be applied in housing space designs. The following conclusions have been drawn from the study. First, it has been discovered that as the residents' quality of life improved, the finishing materials emerged as an important element of housing spaces. It could also be seen that among the finishing materials used in housing spaces, there is recently a growing trend towards various environmentally-friendly advanced materials under the theme of 'the nature' and 'health'. As a result, the need to investigate the standards of discriminatory and efficient housing space designs using advanced materials is on the increase. Second, through the literature and precedent studies, the physical criteria of advanced materials have been classified into five categories: new technology, new manufacturing methods, new materials, complementation and applicability. The main criteria of advanced finishing materials for housing spaces have been classified into four main categories: durability, functionality, economical efficiency and sensibility. By collecting and classifying some key words according to each of these four categories, the representative or combinable features have been extracted. By organizing the advanced materials' physical criteria and their details, some standards based on the physical aspects have been suggested. The features of the finishing materials in consideration of advanced materials have been reclassified into the user-based criteria, environmental criteria and spatial criteria. Through this method, the criteria have been brought up from a new viewpoint, establishing the standards for the advanced materials applicable to housing spaces. Finally, after assessing the criteria by analyzing the advanced materials currently known to be applicable in housing spaces, it has been concluded that the criteria can be used as the fundamental standards. As this study is based on investigating the literature and data, it may be less than reasonable to generalize from the limited number of examples. Hence, it shall be important to make a profound study of some detailed criteria by suggesting more objective standards and analyzing a greater variety of advanced materials.

This study is about Tak Mok theory of feng-shui ideology which was main thought in Choson dynasty or some other thoughts and noble families' thought of garden building : planting trees and properties of the noble families garden. The result from the study of noble family's garden molding is as follows. In the noble family's garden molding, there were considerations of plant ecology known through long experience and the functional aspect of planting tree and esthetic sense of housing circumstances, in addition to feng-shui thought, Taoist thought and the doctrine of the five natural elements of the positive vs. negative. We can learn Choson's noble family's garden included playroom as well as symbolic and incantatory meaning. Also in the thought of noble family's garden molding we can found proper element for modern housing plan such as an ecological peculiarity or functional aspect of dwelling circumstance. And we can also found they didn't show a rejection symptoms against nature but enclosed with straight form which was traditional trait, and each space of it is composed organically. Also we knew they selected a diverse and refined technique with it's decorating the Choson dynasty playful and meditative space. We found that the key point of the thought of noble family's garden molding were on the basis of Confucianal mood, content amid poverty thought and free technique of it.

The scale and nature of the recent earthquakes in the world and the related earthquake disaster index coerce the concerned community to become anxious about it. Therefore, it is crucial that seismic lateral load effect will be appropriately considered in structural design. Application of seismic isolation system stands as a consistent alternative against this hazard. The objective of the study is to evaluate the structural and economic feasibility of reinforced concrete (RC) buildings with base isolation located in medium risk seismic region. Linear and nonlinear dynamic analyses as well as linear static analysis under site-specific bi-directional seismic excitation have been carried out for both fixed based (FB) and base isolated (BI) buildings in the present study. The superstructure and base of buildings are modeled in a 3D finite element model by consistent mass approach having six degrees of freedom at each node. The floor slabs are simulated as rigid diaphragms. Lead rubber bearing (LRB) and High damping rubber bearing (HDRB) are used as isolation device. Change of structural behaviors and savings in construction costing are evaluated. The study shows that for low to medium rise buildings, isolators can reduce muscular amount of base shears, base moments and floor accelerations for building at soft to medium stiff soil. Allowable higher horizontal displacement induces structural flexibility. Though incorporating isolator increases the outlay, overall structural cost may be reduced. The application of base isolation system confirms a potential to be used as a viable solution in economic building design.

The Korean rural landscape has changed significantly due to nationwide modernization and industrialization in recent years. Moreover, as urbanization progresses due to population and economic growth, rural areas surrounding the suburbs of cities are feeling the pressure of encroaching urban sprawl. Use of land for human-made structures such as road and housing development is also increasing, resulting in the destruction of nature in rural areas. Adopting a concept of conserving rural landscape in future development projects is therefore highly desirable.The main focus of this study is to look into the traditional concept of the village and to classify some elements of the traditional rural landscape. Daegu Metropolitan City, the third metropolitan city in Korea, is chosen as the subject of the study. The existing 227 villages have been studied on the basis of their principles and types of village locations in relation to the traditional concepts of 'Feng-shui' and 'Tackriji'. The characteristics of the village location are divided into two aspects: the natural landscape, such as topography, hydrosphere, and azimuth, and the historical and cultural landscape, such as customs(Only the natural landscape aspect is included in this study). The natural landscape, a condition of the village location, is divided into three areas: topography, hydrosphere, and azimuth. There are two types of topography: flatland type and mountain type. There are two sub-types in the mountain type: ridge and valley, which depend on the village location in relation to the shapes of the mountains. There are four types of hydrosphere which include waterways and three directions of mountain depending on the shape: front, behind and side. The direction of the village is analyzed from the direction which the houses in the village face. Therefore, the natural landscape element as a condition of the village location is closely related to the traditional concepts of the village.
