Air-containing fashion, which can offer diverse functions through the inflow and outflow of air, is highly relevant in today's mobile society, where people are experiencing a wider range of environments. This study attempts to suggest the possibility of air-containing multi-functional fashion that could continuously be utilized by developing a design for an air-containing jacket using modular systems. In this research, the modular systems in architecture and furniture design were referenced through a review of the literature for the purpose of establishing modular systems in fashion. Functions relevant to the mobility of today's society are derived from the results of advanced research and applied to the design of modules of the jacket. The modules are integrated through the modular systems. The folding and unfolding structure in architecture and furniture is applied as a folding system in fashion, the vertical accumulation structure as a layering system, and the horizontal integration structure as a combining system, and in addition, the containing system has emerged in fashion. Each module is designed to fulfill certain functions, such as cushioning, heat insulation, and portability. The folding system is utilized in designing the cushion module to support the neck and back of a wearer by making its hood and hem fold in the back. The application of a layering system was suggested by making the vest, combined with the neck cushion and back cushion via the combining system, layered with its insulation module. By applying the combining system, the hood that includes the neck cushion, the skirt that includes the back cushion, the body that includes the insulation module, and the sleeves can be connected and separated by a zipper. The applicability of this concept was proven by applying a developed design to an actual item.

In 21 Century, people's living standards and material requirements have been continuously improved with the development of society. The demand for commercial space is not merely content with purchases. What's more, the consumers want to experience some activities offered by the brand while shopping. In this paper, we mainly research the spatial structure and the spatial expressional characteristics of brand lifestyle shop of Korean brands built in Seoul area. First, through the documentary research, we get the four characteristics of interior space performance of brand lifestyle shop, which are, interaction, proximity, symbolism and compound. Secondly, we select 8 brand lifestyle shops in the Seoul area as the object of this study, and analyze the actual application of the four characteristics in these cases. Thirdly, through the analysis of case study, we make a concrete analysis of the expressional characteristics of Korea's brand lifestyle shop. Finally, we reach the conclusions: First, the brand lifestyle shop provides space for both brands and consumers to communicate with each other. Second, in brand lifestyle shop there is a special space which is different from the other commercial space. The existence of this special space makes brand lifestyle shop more personalized and more specialized, and makes the customers have more interesting when they are shopping. Third, compared with the sales space, the non-sales space accounts for a larger proportion. Fourth, in spatial representation, interaction plays a role in connecting brands with consumers. Fifth, brand lifestyle shop has the same spatial concept, but it has different application and embodiment in each case. Each brand lifestyle shop has its own unique features. This is the economic strategy used by brand sustainable development and expansion.

Since the Korean War, Korea has experienced modernization. The population increase by baby booming has asked for more space for educational facilities. In such a situation, the purpose of educational facilities was to accommodate continuously increasing students, rather than seeking for quantitative demands. In addition, in accordance with social changes, educational shifts were required. After the revision of the seventh national curriculum in education in 1997, the school buildings became varied. The design of buildings in accordance with educational curriculum has been improved, but still lack of forming comfortable environment and considering energy efficiency in school buildings. For the improvement of educational environments, educational media such as TV and computers have been provided, and energy systems, including heating and cooling systems, has been continuously increased. As a result, it appeared that energy use in school buildings and facilities has been steadily increased and that the structure of energy consumption has been also changed, especially with regard to electricity use. Living in the 21st century, human beings face global environmental issues, such as global warming, geographical climate changes, and ozone destruction that are the consequences of fossil energy use. Therefore, even in industrial areas, considering a counterplan for low energy use is being paid attention. Starting with Kyoto Protocol in 1992, people try to decrease carbon dioxide and to develop alternative energies (i.e. natural energy); for example, solar energy, wind force, terrestrial heat, and water power. Advanced countries already set up a criterion for $CO_2$ decrease ranging from office buildings to residential houses and also propose alternatives for the $CO_2$ decrease. However, there is no such a plan for low energy use and $CO_2$ decrease in school facilities, and any research on the actual conditions was not accomplished. Thus, this study examines energy demand in classrooms that take up a large portion of energy demand in school building structure.

홀로그램은 아날로그 홀로그램과 디지털 홀로그램으로 구분되지만 일반인이 구현하기에는 고가의 장비나 콘텐츠 구현의 한계가 존재한다. 또한 정해진 동영상을 통해 무한 반복되는 콘텐츠나 수동적인 관람 등 기존의 정적인 형태에서 벗어나 인터랙션이 가미된 홀로그램 콘텐츠를 연구해야 할 필요성이 있다고 사료된다. 따라서 유사 홀로그램 중 플로팅 홀로그램을 중심으로 융복합형 영상시스템을 제안하고자 한다. 홀로그램 인터랙션 요소는 3차원 공간에서 카메라 높이, 3D 모델간의 간격, 모델의 중복, 스케일, 애니메이션, 포지션, 칼라, 3D 모델체인지 등 8가지이며, 관람자가 실시간으로 직접 컨트롤하는 플로팅 홀로그램은 값비싼 홀로그램 장비를 사용하지 않고 플로팅 홀로그램을 쉽게 제작, 융복합 영상시스템을 활용함으로서 보다 대중적이면서도 능동적인 홀로그램 콘텐츠 제작 방법론을 제시하였다. 연구한계점으로는 실제 전시를 통해 개발된 영상시스템과 피드백을 통하지 못한 점이며, 이를 지속적으로 보완하여 보다 완성된 홀로그램 영상시스템이 개발되기를 기대해 본다.

Cultural heritage means a great lot to a nation's social system and its people's behavior consciousness and plays an important role in its self-development and improvement. It is essential for a nation's self-education and renewal. Improper cultural heritage will be disastrous because it may fall a nation into a loss of terrible chaos. Only the proper cultural heritage can make it always self-awaking, self-correcting and remaining vital in life. This paper, from the perspective of Choi Bu's Pyohaerok, makes a thorough analysis of the unbalance heritage of Chinese ancient culture for thousands of years. For example, many fine traditions gradually vanished in our actual life or only take half their life in heritage nowadays, such as our ancient broad and profound Confucian etiquette, ancient exquisite brocade art and architecture, ancient advanced ship-building technology and many other advanced numerous technological inventions; however, too much unwanted cultural rubbish keeps constant prevailing and takes repeated successions in the life, such as the heavy-form-and-light-content management mode, borrowing power to do evil, neglecting technological inventions long time and generally believing in ghost theory,etc.. This paper mainly focuses on the partial successions of the bad cultural heritage and its bad influence on the country, and concludes that it is just that that makes the country more and more backward. Therefore, the paper makes some pondering over these issues and proposes some related ideas of country-building to attract others participation to deal with them.

This study aimed to find the components of visual image by researching main image-related adjectives applied to high-waist skirts. In addition, it compared and analyzed the differences and mutual influences of visual images according to variations in the waistline and skirt length of high-waist skirts. The researchers made nine high-waist skirts-combinations of three different levels of waistlines and skirt lengths. The test involved 121 people who hold degrees in the field of Clothing and Textiles. The panels tested actual images of all models wearing the high-waist skirts shown on a computer screen. The results of the study are as follows.: Four factors affected the visual image as waist-height and skirt-length changed: attractiveness, upper-body compensation, length compensation, and hips compensation. Among these factors, attractiveness was estimated as the most important factor. The torso and the hip were highlighted as the waistline increased from 3cm to 11cm, due to the optical illusion of a tighter skirt wrapping the bust, waist, and hips. As the waistline increased, the stature and leg length increased, possibly revising the overall appearance. For the skirt length, a length measuring 20cm above the knees, proved to be most attractive. This resulted in elongated height and leg length, and a slimmer overall look.
