In this study, the concept of environmental-friendly architecture, where environment is importantly regarded as a design concept in modern architecture and the meaning of boundary are examined, To apply properly design methodologies along with the importance of environment, the concept of environmental-friendly architecture should be first correctly established. And as the recent rapid development of technologies provides new possibilities for environmentally-friendly architecture, it is needed to have a new boundary concept and the interpretation of the meaning of boundary differentiated from the one of existing architecture. Recently the meaning of boundary is expanding its range to the relations with its neighboring environment beyond the relations with in and out of a space and has also the role as a medium for exchange and communication instead of breaking-off. Therefore, the boundary of environmental-friendly architecture alongside physical boundary is extended to the area for communication. Here, a basic boundary of architecture is maintained, but its meaning and expressions get natural shapes. The study deals with the analysis of the concept of environmental-friendly architecture and its changes from the perspective of times, environment and social backgrounds and seeks its appropriateness centered on environmental-friendly architecture Since 1980s when the issues of human and environment were raised in earnest.

Recently, the aspect of consumers' preference for design has been changed to a pattern of respect for personality, based on 'personal value of passion'. The differentiated personal passion of modern people does not allow them to select mass-produced industrial product, and leads them to choose life style different from others. Specially, consumers want to express. their differentiated personality by preferring and possessing the originally designed products. Therefore, the originally designed products that are clearly identifiable become the object of consumers' consideration, and stimulate the consumers' desire to purchase. According to new needs of consumers, it is required to reconsider the old design pattern of furniture based on simplicity and propose new design for furniture to meet the needs of consumers. Mass production has resulted in a strong focus on simplicity rather than difficulty and complexity of the production process. This tendency shows the design pattern that leans toward one side excluding the expression of correlative concept among design elements. This one sided design leads modern people to have no personality, and shows only simple and uniform expression of passion. Therefore, this paper is purposed to develop furniture with more personality by applying correlative concept that has been taken less seriously in the field of design to furniture design.

In the digital age, as it is ambiguous to distinguish between the original and a replica, the order of reproduction which is more realistic than the reality is becoming a new cultural order. Before the period when digital paradigm dominates, always the reality has been an object to be copied. But, today is an age of Simulacre where code of digital technology dominates. Such a phenomenon is shown in the construction space without exception Gilles Deleuze who was a representative philosopher of the post-structuralism depicted the concept of Simulacre as an instant 'event' passing by without change in an object or substance. As the result of analyzing what kinds of feature for the concept of event is expressed in the digital space, a diagram itself could be a design process, the digital space with correlation was able to be created through the change in the meaning according to the changing image and my body which was the leading part to form primary space. In such a meaning, this study pays attention to Deleuze's 'Event(Simulacre)' concept. At this transitional period when a new concept of digital space is about to take root, the modern philosophers' theories and the discussions about spatial relativity should be continually studied, along with the development of spacial theories for the modem construction.

Objectives : The verse, "冬不藏精, 春必病溫", which had much influence, has been falsely referenced as contents of "Neijing". This study aims to examine this process, while looking at its theoretical meaning within clinical practice. Methods : The origins of the concept "冬不藏精, 春必病溫" are explained through annotations of "Neijing" and Li Dong Yuan(李東垣)'s interpretation of Shanghan(傷寒), while its clinical meaning is examined through theories of doctors's who applied the concept in their practices. Results : The beginning of "冬不藏精, 春必病溫" could be traced back to Li's annotation of the verse "冬傷于寒, 春必病溫" from the "Neijing", where he based his understanding on the concept "少陰不藏." Since then, the discourse on "冬傷于寒, 春必病溫" has been replaced by "冬不藏精, 春必病溫" as a new concept to explain the pathology of Wenbing(溫病). These discussions followed the line of thought that by failure to store Jing(精) during the winter, Cold pathogen would infiltrate, hiding itself in Shaoyin(少陰). Various arguments on how the Cold pathogen would develop into Wenbing and its treatment followed. Conclusions : "冬不藏精, 春必病溫" can be understood as the result of a new interpretation of "冬傷于寒, 春必病溫" through the perspective of Cold pathogen infiltration based on "少陰不藏".

The concept of Space-time is performed while the movement of human Is imaged on coming 20th century up. Specifically it is considered that the movement of human is caused by the relativistic otherness rather than an absolute subject in space of deconstructive tendency. The purpose of this study is that I try to analyze an expression of relative space-time concept in desconstructive tendency and I have to get a concept how this kind of expression effect the contemporary commercial space. Through this study, I can get to know that the expression of relative space-time concept expresses the dynamic construction by the indeterminacy and the visual effect by the dematerialization in the contemporary commercial interior-space. According to the result of study, the concept of space get to be more meaningful, relative space-time concept and it can be attributed to the concept of human's new creative space over human's life in general.

In general, thickness of the sublayers under track is designed based on concept of vertical soil reaction value or vertical stiffness. However, this design method cannot take consideration into soil-track interaction under repetitive load, traffic condition and velocity of the train. Furthermore, the reinforced roadbed soils experience complex behavior that cannot be explained by conventional stress-strain relation expressed as soil reaction value k. The reinforced roadbed soils also can produce cumulative permanent deformation under repetitive load caused by train. Therefore new design method for the sublayers under track must be developed that can consider both elastic modulus and permanent deformation. In this study, a new design concept, a rule-of-thumb, is proposed as the form of design monograph that is developed using elastic multi-layer and finite element programs by analyzing stress and deformation in the sublayers with changing the thickness and elastic modulus of the sublayers and also using data obtained from repetitive triaxial test. This new design concept can be applied to design of the reinforced roadbed before developing full version of design methodology that can consider MGT, axial load and the material properties of the layers. The new design monograph allows the user to design the thickness of the reinforced roadbed based on permanent deformation, elastic modulus and MGT.

Although there are many kinds of advanced ballast water management systems, pioneering studies for ballast-water free ship and minimal ballast water ship concepts are in progress. In this study, the existing alternatives of ballast water are reviewed and a new design concept is studied on the basis of the existing bulk carrier hull form. To develop a new design alternative which has minimal ballast for ballast water discharge free operation, the new concept should have technical feasibilities that are related to the role of the ballast water, berth access, loading constraints, etc. For this purpose, a simplified systems engineering basis design approach is adopted using a business model as the system analysis and control tool. To check the performance feasibility of the new concept, ship resistance performance is reviewed based on a model scale ship resistance performance analysis.

This study is to clarify the concept of \"Americanization\" among korean modern clothing culture by investigating magazines from 1920s to 1930s. The Americanization of modern clothing culture can be divided to New fashion, Sports-wear, and Cloth improvement. 1. New fashion, Western culture was the main stream of new fashion, and modern boys and girls could bear cultural privileged consciousness. And the spread of modern culture was so fast that exaggerated fashional preference provoked extravagancy and loss of individuality. 2. Sports-wear. Under the rule of Japanese imperialism, initial sports activity was encouraged to regulate colony by principle and order. Through the sports-wear, practicality of clothing, exposure of female body, and the concept of T.P.O.(Time, place, occasion) were introduced. 3. Cloth improvement. The capitalism and modern concept of \"time\" were introduced and promoted maximum productivity. And to increase productivity, imperialist educated conveniency of western clothes and inconveniency of traditional Korean clothes. These could affect Koreans to think themselves a sense of inferiority(uncivilized complex).ncivilized complex).
