Space dominates all the art activities human do and plays a role of providing aesthetic emotion. Architecture, sculpture, painting, and furniture, etc. these two and three dimensional works are represented in space and interpreted the role of its form, structure and function. Each area is different, but space has been studied in philosophy, physics, geometry, and mathematical studies, etc. and has been consistently interpreted and represented relating to a variety of human creative activity. Furniture is also three dimensional art being dependent on space. In the United States in 2004, I made the living room bench by applying the spatial concept at Rochester Institute of Technology. Two years later, this design was adopted by wendell Castle Collection, an American furniture company, then prototype were made and tested three times during a year, and then since 2007 as indoor benches it has been manufactured in the United States. The study's purpose is to order the process of its development based on the experience of bench production applied the spatial concept, and by analyzing the properties of spatial concept, I am planning to propose a new concept on interaction with the space and furniture for next.

In a previous study, design charts where proposed to help the torsional design of axially restricted reinforced concrete (RC) beams with squared cross section. In this article, new design charts are proposed to cover RC beams with rectangular cross section. The influence of the height to width ratio of the cross section on the behavior of RC beams under torsion is firstly shown by using theoretical and experimental results. Next, the effective torsional strength of a reference RC beam is computed for several values and combinations of the study variables, namely: height to width ratio of the cross section, concrete compressive strength, torsional reinforcement ratio and level of the axial restraint. To compute the torsional strength, the modified Variable Angle Truss Model for axially restricted RC beams is used. Then, an extensive parametric analysis based on multivariable and nonlinear correlation analysis is performed to obtain nonlinear regression equations which allow to build the new design charts. These charts allow to correct the torsional strength in order to consider the favourable influence of the compressive axial stress that arises from the axial restraint.

In 2016, a handmade vehicle called to the VF-3 was designed and manufactured as a formula typed car. Prior to manufacturing and assembly, the impact attenuator was analyzed through ANSYS LS-DYNA, and the results were applied to the VF-3. The dynamical performance of the VF-3, such as the acceleration and circling simulations, was also assessed through MSC-ADAMS. The results were applied and compared after the Korean Society of Automotive Engineers (KSAE) competition. There was only a 0.8 s difference in the acceleration test. In order that the frame was not twisted by thermal deformation, Argon-TIG welding was used and a zig was designed. Another zig was designed to have the exact position for the hardpoints in the suspension system. Most of the parts were made with aluminum 7050 for reduced weight. The VF-3 won the third prize in the 2016 KSAE Student Handmade Vehicle competition.

In order to increase the productivity of electrical parts, manufacturing processes using progressive dies have been widely used in the industry. Motor cores have been fabricated using progressive stacking die with the lamination procedure for better electro-magnetic property. For the proper design off process, a prediction of the process is required to obtain many design parameters. In this work, rigid-plastic finite element analysis is carried out in order to simulate the lamination process of the motor core. The effects of the embossing depth, the amount of deviation, and the number of stacked sheets are investigated and compared with experiments. The forming process can then be predicted successfully from the results of analyses, which enables an appropriate design to be made for the die and the process.

Modern architecture does a role in terms of connecting traditional and current architecture. In the same time, Which is important part of korean architecture history because of introduction of western architecture. Accordingly, At this meaninglessly going out and leaving of modern architecture, the purpose of this study is systematic researching of the modern Government Office interior. I progressed this study to research into the period context at construction of the modern Government Office and tendency of architecture and interior at that time. And then understand interior space organization of it. The early modern Government Office adopted Neo-Baroque style from tendency of that time. Also, showed composite order which is mixed in the Greek temple, the Renaissance and the classic style representing the power. But, after late 1920 It adopted Modern Style. This characteristic is different from current composit order, which is comprehended by our. In order to understand aesthetic value of current straight interior space, It have to be interacted the present and past. But It's averted because it was made in the period of Japanese imperialism.

With the subjects of male consumers in their 20s to 40s living in the Ningbo area in Zhejiang Province, this study aims to investigate into the reality of their purchase attitude and size fitness of ready-made suits. The results are as follows; Looking into their demographic characteristics, 70.6% of the subjects were twenties, 60.6% were single, and educational career stood in the order of college, middle school, and high school graduation. They were largely absorbed in free trade, followed by teaching, commerce and service industry. 59.6% of them were Zhejiang Province belongs. One to two thousand yuan was the greatest portion of their monthly income. As for their purchase attitude of ready-made suits, they thought higher of material, quality, activity, and solidity than of design. They preferred to buy clothes at a department store. There was significant difference between purchase frequency and purchase price according to monthly income and jobs. Concerning brand recognition, the Chinese subjects favored "Youngor." Though Korea's brands were very lowly recognized, Korean products received really high recognition. Compared with China's brands, they found foreign brands excellent in design, followed by material/matter, wear, and sewing. As to their physical satisfaction and the size fitness of clothes, most subjects felt happy with their sizes. Trousers and jackets were among the unfitting suit items, while the girth of waist was the least satisfactory size. Therefore, in order to raise the market occupation rate of Korean suit goods in China, more aggressive marketing strategies are required to utilize the current Korean-style entertainment and maximize concerning brand images. In particular, outstanding products in consideration of prices should be made through the proper patternmaking to reflect the body types of the Chinese.
