This study investigates the factors of LOHAS (Lifestyles of Health and Sustainability), to segment consumer groups by LOHAS and identify the differences of LOHAS groups in the purchase of LOHAS fashion products. A total of 398 people aged from 20s to 50s were surveyed in September, 2009. The data were analyzed with factorial analysis, ANOVA, LSD, Chi-square, Cronbach' ${\alpha}$, using the SPSS 12.0. The survey showed: 1) Seven LOHAS factors (environment preservation, family centered, pursuit of rural life, preference of environmentally friendly products, interest in health, pursuit of leisurely life, and soul & body balance), 2) LOHAS consumers were classified into five segments (health interest, well-being, LOHAS, unconcerned, and naturalist). The distribution of age level, education level, and the type of job were different among LOHAS groups; and 3) Experiences of purchasing LOHAS AS fashion products in the past and intention to purchase LOHAS fashion products in the future were different among LOHAS groups.

Pureundeul fanning corporation(PFC) is an cgmplary body of all producer organizations for environmentally friendly agriculture(EFA) in Korea. It is located at Asan in Chungnam and has 301 farmers. They attained more than 10 billion wons as a sale in 2004. And The direct marketing channel of the EFA products is the second logistics center(Asan) ${\to}$ the first logistics center(Gwangju Gyunggi) ${\to}$ local hansalim shops ${\to}$ consumers. It is needed to construct the system of the direct marketing as follows : First, it needs to construct the direct marketing system within the region for EFA products of Asan. Second, the direct shop and suppling area should be enlarged as a way to promote sales with the demand increase of EFA products. Third, an aggressive promotion campaign is be needed for increasing motivation of consumption and understanding of EFA products.

Growth of pigs is influenced by many factors. To assist pig producers in the evaluation of alternative feeding and management strategies growth models have been developed. In the Netherlands the Technical Model Pigfeeding (TMV) is developed. This model predicts the influence of feed intake, feed composition, genotype, sex and climate on growth, body composition, gross margin and mineral excretion of healthy growing/finishing pigs. The purpose of TMV is to support information services, feed companies, researchers and students. In addition to providing accurate predictions, a model should also be user-friendly and wishes of the user should be taken into account to stimulate application of the model in practice. In this paper, the theoretical background of TMV and a methodology to stimulate application of models in practice will be described.

In the S.C.W (soil cement wall) grouting solution, Cement grout ratio of 1 part Portland cement and 1part water is being used. However, Co₂ and harmful heavy metals such as cr6+ are discharged in the process, causing a serious environmental issue. The purpose of the present study is therefore to substitute cement grout to inorganic binder and identify durability properties of ground solidification materials.

Nowadays, high speed train has settled down as a fast and convenient environment-friendly transportation and it's need is gradually increasing. However increased train speed leads to increased aerodynamic noise, which causes critically affects comfortability of passengers. Especially, the pantograph of high speed train is protruded out of train body, which is the main factor for increased aerodynamic noise. In this research, to reduce aerodynamic noise pantograph, panhead's shape changed to aerodynamical shape. aerodynamic noise of pantograph is predicted by CFD (Computational Fluid Dynamic) and FW-H (Ffowcs Williams-Hawkings) equation. Also, the sound pressure level of aerodynamic noise of base and modified models are predicted. And the reduction effects of the sound pressure level is analyzed.

Recently, the railway has been growing as the eco-friendly transport which is excellent for reducing carbon dioxide. However, the level of using tools to quantitatively and objectively evaluate the environmental performance is still low in the rail industry. Therefore, it is necessary to introduce Environmental Product Declaration(EPD) which describes the environmental performance by using Life Cycle Assessment(LCA) for evaluating the environmental impacts through entire life cycle of a product. The EPD enables stakeholders including policy makers, operation body, vehicle manufacturers and drivers and consumers to be informed about the superior environmental performance of rail vehicles.

It is essential to investigate the structure and the main characteristic of Home USN (Ubiquitous Sensor Network) technologies in built ubiquitous environment while designing bio-sensors. For this study, Thermistor elements and Thermopile black body have been selected to implement ubiquitous technologies for bio-sensors and wireless network such as WiBro has been used to transfer sensing data to the BSN (Bio-Sensor Network) gateway. It is certain that efficiency of ubiquitous space design is improved if main components of each specific sensor network are analyzed precisely in digital way and corresponding communication modules are prepared accordingly. Ubiquitous technology, in conclusion, has to be applied not only with systematical mechanism or electronic setting but in human-centered atmosphere as well, keeping with deep consideration for bio-housing service factors in eco-friendly surrounding.

NUI is a motion interface. It uses the body of the user without the use of HID device such as a mouse and keyboard to control the device. In this paper, we use a Pi Camera and sensors connected to it with small embedded board Raspberry Pi. We are using the OpenCV algorithms optimized for image recognition and computer vision compared with traditional HID equipment and to implement a more human-friendly and intuitive interface NUI devices. comparison operation detects motion, it proposed a more advanced motion sensors and recognition systems fused connected to the Raspberry Pi.

Numerical analysis of hydrodynamic performance of a movable submerged breakwater was carried out as an eco-friendly marine structure for coastal and harbor protection. Using boundary elements method with two-dimensional frequency-domain reflection and transmission coefficients and wave forces acting on the submerged flat plate were calculated with various submerged depths and respective motion allowable modes. The movable breakwater was found to be more efficient in wave-blocking than the fixed structure. Variation of reflection coefficients was significantly influenced by vertical motion of the body.
