It is treated more seriously than ever as the customer requirements are becoming a high-quality and diversification. Among the various elements to affect customer's evaluation of automobile quality, BSR(buzz, squeak, rattle noise) are considered to be a mostly contributing factor. Rattle Noises in cockpit modules are one of the major concerns mentioned above. Recently, measurements of the BSR noise between the parts that make up the products from the perspective that the structural causes. For structures that make up material has not been any consideration of the BSR noise characteristics. The aim of this study is to clarify the characteristics of noise occurrence in vehicle cockpit module that consist of plastic material after measuring noise by rattle special testing instrument.

The domestic textile industry is currently making an active effort to present high value-added materials that can respond immediately to the wants and needs of consumers sensitive to the of originality of design and emotionally appealing fashion materials. This paper attempted to present the creative development of materials in the contemporary clothing culture in which consumers' needs are individualized and differentiated and the cycle of life in fashion materials is getting shorter. To be specific, the paper presented the texture of peculiar expression to diverse cotton materials using the Woolsmok technique in the processing of felt. The chosen Merino wool was felted to 8 kinds of cotton with different density and structure. The touch, texture, visibility and complex susceptibilities of new materials were presented as different materials of cotton and wool were transformed into one material. In felting cotton fiber through wool, the transformation of diverse textures was presented and compared in the method using the washing machine in an attempt to enhance the efficiency of the traditional craft technique and work. This study proposed the possibility of placing the new material made up of cotton and wool beyond the range of functionality of each simple material, activating it as the peculiar material and expanding it to the range of its use as fashion material in the clothing industry. It is expected that this material will become competitive material at home and abroad by being activated as the clothing material of artistry, workability and marketability that can satisfy the tastes of consumers who call for high quality and diversification.

This study was conducted to identify the sedimentation quantity and settling velocity, sediment fundamental data that an important position of water quality management of Seston, POC, PP and PN in Nakdong river basin using a sediment traps to collect suspended material pollutants. Nakdong river basin is that average sedimentation quantity of seston, POC, PP and PN were 124~1,125 g/$m^2$/d, 2,963~25,072, 26~347, 445~2,184 mg/$m^2$/d, respectively. Settling velocity of Seston, POC, PP and PN were 17.0, 35.5, 8.7, 2.4 m/d. It was appeared that various results according to the river flow, weather and other environmental factors. There was no significant correlation, each suspended material pollutants. Sedimentation rates are likely to be overestimated because the flow is not considered to resuspended materials. Therefore diversification through continued monitoring is needed to be analyzed.

As the proliferation of hydrogen electric vehicles accelerates, there is observed diversification in hydrogen refueling station models. This diversification raises safety concerns for different types of stations. This study conducted a quantitative risk assessment of a multi-vehicle hydrogen station, capable of simultaneously refueling cars, buses, and trucks. Utilizing Gexcon's Effects&Riskcurves Software, scenarios of fire and explosion due to hydrogen leaks were assessed. The study calculated the impact distances from radiative heat and explosion overpressure, and measured risks to nearby buildings and populations. The largest impact distance was from fires and explosions at dispensers and high-pressure storage units. High-pressure storage contributes most significantly to personal and societal risk. The study suggests that conservative safety distances and proper protective measures for these facilities can minimize human and material damage in the event of a hydrogen leak.

The main scope of this study is to define such system of space composition factor to diversify the interior space of the apartment housing. Staring from the space analysis, identification of the design factors, characters of the anthropometry for the dwelling behavior, and analyzed dimensions of the interior furniture from the market data have uniformly integrated to engage with such system for innovation and diversification of the space design method. The elements of the composition factors are as follows: 1. Structural elements - $\circled1$Bearing wall $\circled2$Ceiling $\circled3$Floor $\circled4$Structural column 2. furniture elements - $\circled1$Fixed furniture $\circled2$Movable furniture $\circled3$Non-bearing wall $\circled4$F1exible wall $\circled5$Void & Solid 3. Finished material elements - $\circled1$Structural material $\circled2$Doub1e shell $\circled3$Color & Tone $\circled4$Lighting system For the design system selected space in restricted in 3way directional axis X,Y,Z to form its volume and direction of the space composition factors. X-axis is stands for horizontal length of the factor, Y-axis is for the space depth, and lastly, Z-axis is for the hieghts of the space based on anthropometris.

Recent interest in the construction sector, rising about the environment and eco-friendly recycled material resources, and increase the development of method But despite these efforts, and the diverse functional and structural changes in the structure can not be an appropriate response to the functional waterproof structural changes in the structures and appropriate response Diversification does not waterproof and functional issues such as durability, and which are occurring due to the structure to secure stability and durability, never sees the conservative economic losses due to import constructability reinforcement situation. Therefore, this study applies to structure the existing waterproof method (hereinafter referred to as structures water-resistant methode), and to review recent issues of environmental pollution and resource waste, and taking on environmental issues, such as Revelation and functional Inorganic mixed in a way to leverage the manufacturing water-resistant material "Re Inorganic, functional and environmentally friendly high-viscosity mix asphalt waterproof rubber reinforcements, and taking conservative" for the characterization and performance assessment to the issues raised by the structure and whether the judge would respond.

Rebar work takes up big proportion in a construction work. The current process of purchasing, cutting and election, and working of rebar induces a lot of loss in rebar. This study is focused on analyzing the problem and the present condition of the process from the calculating of rebar quantifies to the actual constructional stage through surveying those who have experience in the estimation department, or the construction site of a domestic construction company. Many reform measures such as diversification of standard(i.e., 8-meter)bar, calculation of rebar quantities and construction according to the rebar election drawing, expansion of accuracy in layout plan, thoroughness in examination of layout plan in advance, utilization of the worked material, systemization of rebar control(management), and a shift in attitude of the field(site) manager were proposed as the result of the survey.

Korea furniture industry is the difficulty of producing manpower supply and demand together with rising raw material and are facing severe difficulties as a diversification of consumer needs. It located so close through the International Furniture Fair in China and to identify the status of the domestic furniture industry. It also overlooks want to move forward in the direction. China International Furniture Fair was the head of the leading exchanges for furniture production worldwide. Market demand as households, yet the center is fully equipped with the chance to cooperate with the furniture production. The Shanghai International Furniture Fair was responsible for, such as providing ideas and partners for product development and production paths excavation of korea furniture manufacturers itgetda which can have a significant driving force in overcoming the recession and evaluated through this.
