'Interaction' here means an action that reciprocally affects each other. In this action each change and movement does not exist independently but acts upon each other. The interaction of fashion design has undergone a lot of changing experiences. Besides it assumes the role of an appreciator that participates in the formation of work. This interaction breaks down the distinction between the designer as the maker and presenter of dress and the passive dresser and appreciator as its passive receivers.. Finally, it integrates the creator, receiver and technology altogether. The interaction tendencies of fashion design treated in this study are classified into four types. First, the mechanism that is included as a part of work and the cognitive response that the observer experiences. Second, the response that fashion design displays towards the stimulus of circumstances. Third, the changeability of manipulation of fashion design. Fourth, the control that mechanism acts upon dynamic status by technology. As in may other fields of our life, interaction in fashion design reflects the change and interactivity of our thinking and ideas.

In this paper, possibility of controlling motion of a floating structure using a tuned liquid damper (TLD) is numerically investigated. A TLD is a tank partially filled with liquid. Sloshing phenomena of liquid inside a tank can suppress movement of the tank subject to external excitations at specific frequency. The effects of sloshing phenomena inside a rectangular floating body on its sway motion are investigated by varying excitation frequency. First, a grid-refinement study is carried out to ensure validity of grid independent numerical solutions using present numerical techniques. Then, sway motion of the floating body subjected to wave with five different frequencies are simulated. The normalized amplitudes of sway motion of the target floating body are compared over the frequency, for cases with and without water inside the floating body. It is shown that the motion of the floating body can be minimized by matching the sloshing natural frequency to excitation frequency.

Disasters, including earthquakes and landslides, have enormous economic and social losses besides their impact on environmental disruption. Iran, and particularly its Western part, is known as an earthquake susceptible area due to numerous strong ground motions. Studying ecological changes due to climate change can improve the public and expert sector's awareness and response to future disastrous events. Synthetic Aperture Radar (SAR) data and Interferometric Synthetic Aperture Radar (InSAR) technologies are appropriate tools for modeling and surface deformation modeling. This paper proposes an efficient approach to detect ground deformation changes using Sentinel-1A. The focal point of this research is to map the ground surface deformation modeling is presented using InSAR technology over Sarpol-e Zahab on 25^th November 2018 as a study case. For surface deformation modeling and detection of the ground movement due to earthquake SARPROZ in MATLAB programming language is used and discussed. Results show that there is a general ground movement due to the Sarpol-e Zahab earthquake between -7 millimeter to +18 millimeter in the study area. This research verified previous researches on the advanced image analysis techniques employed for mapping ground movement, where InSAR provides a reliable tool for assisting engineers and the decision-maker in choosing proper policies in a time of disasters. Based on the result, 574 out of 682 damaged buildings and infrastructures due to the 2017 Sarpol-e Zahab earthquake have moved from -2 to +17 mm due to the 2018 earthquake with a magnitude of 6.3 Richter. Results show that mountainous areas have suffered land subsidence, where urban areas had land uplift.

In this research a numerical simulation method is developed for moving body in free surface flows using fixed staggered rectangular grid system. The non-linear free surface near the body is defined by marker-density method. The body boundary is defined by line segment connecting the points where the body surface and grid line meet. Continuity equation and Navier-Stokes equations are used as governing equations and the equations are coupled with two-step projection method. The velocities and pressures of body boundary and free surface cells are calculated with simultaneous iterative method. To treat a body movement in a fixed grid system, the volume displaced by moving body is added to the divergence of the body boundary cell. For the verification of the present numerical method. vortex shedding period of advancing cylinder is calculated and the period is compared with existing experiment results. Moreover, added mass and damping coefficients of a vertically excited box are calculated and the computed results are compared with published experiment results. Impulsive pressure and water level variation due to sloshing phenomenon are simulated and the results are compared with published experiment results. Varying the plunger shape, the waves generated by plunging type wave maker are compared with the 2nd order Stokes wave theory The plunger shape generating the wave that shows the best agreement with the theory is represented.

This paper presents a real-time indoor location and pose estimation method that utilizes simple artificial markers and image analysis techniques for the purpose of warehouse automation. The conventional indoor localization methods cannot work robustly in warehouses where severe environmental changes usually occur due to the movement of stocked goods. To overcome this problem, the proposed framework places artificial markers having different interior pattern on the predefined position of the warehouse floor. The proposed algorithm obtains marker candidate regions from a captured image by a simple binarization and labeling procedure. Then it extracts maker interior pattern information from each candidate region in order to decide whether the candidate region is a true marker or not. The extracted interior pattern information and the outer boundary of the marker are used to estimate location and heading angle of the localization system. Experimental results show that the proposed localization method can provide high performance which is almost equivalent to that of the conventional method using an expensive LIDAR sensor and AMCL algorithm.

This paper focussed to find out the consumer appraisement and purchase consciousness on organically grown products since public pay more and more attention on organic food and market for organic products has been grown very rapidly. It is intended to deliver the necessary information at first time in Korea to the policy maker for environmentally sound agriculture, establishment for marketing strategy and consumer movement related with it. 66.2% of investigated consumer ever purchased the organic products, and they are inhabitant in apartment complex, belongs to high income group and eldly people, and used to buy frequently at 45.8%. For the reason why they choose the organic products ; 84.7% for health and safe, 48.6% for taste. But the reason why they not choose the organic products ; 56.7% for unconvenient to shop an organic food, 51.4% for expensiveness. On the purchasing the consumer mainly rely upon the certification label(67%), the marketing place(29.6%) and information and recommendation of shopkeeper(23.6%). Korean consumers intend to buy an organic products if variable products and crops are offered in the market and offered at reduced price. The group purchased intensively the organic goods appraise for an organic products positively, and group who do not express any careless intend never to purchase an organically grown products because of its high price. Consumer indicated the support policy and action program by government(69.2%), research & development on organic agriculture and its extension activity(48.8%) are necessary to stimulate an organic agriculture in Korea.
