The purpose of this study is to analyze the various cinematic gaze and its realization through Seojong MA-Residence in Yangpyeong-gun, completed in 2016. This paper will focus on what kinds of cinematic concepts and design ideas were selected and considered in the stage of concept design, then how the site plan, floor plan, elevation and section design were developed in the stage of schematic design, and finally how much of the design intentions were successfully realized to the residential building. Architectural sketches, physical models and drawings at the concept & schematic design stage were reviewed. After the construction, some important issues were successfully realized such as interesting cinematic views to outside, visual openness and inflow of sunlight.

Concrete has cracks from shrinkage that necessarily result from in hardening process. Shrinkage-reduced concrete developed for crack reduction was utilized at a sample construction project. As a result, it is confirmed that crack initation ratio was remarkably reduced when compared to the case of normal concrete utilization. Additional sample project is supposed to use delay joints as well as srinkage-reduced concrete. Subsequently, the result will be reported. The greatest factor which affects in drying shrinkage is unit quantity of water. However, there are a lot off difficulties in field supervision because proper measuring means is not presented in present standard. Therfore, problems depending on ready-mixed concrete concrete companies should be improved by preparing the related standard assoon as possible.

This paper presents collision avoidance using model predictive control algorithm. A model predictive control algorithm determines lateral tire force and yaw moment and steering angle input and differential braking input is determined from lateral tire force and yaw moment. A constraint for model predictive control is designed for obstacle avoidance. A objective function is designed to minimize lateral tire force and yaw moment input and to follow changed lane after collision avoidance. The performance of proposed algorithm has been investigated via computer simulation conducted to vehicle dynamic software CARSIM and Matlab/Simulink.

This study was carried out to examine if Haejohwan (HJ) inhibits oxidant-induced lipid peroxidation and therby produces protective effect against thyroxine-induced hyperthyroid rats. Triiodothyronine $(T_3)$, thyroxine $(T_4)$, lipid peroxidation, xathine oxidase activities and type conversion ratio were increased in thyroxine treated group. However, they were decreased in HJ extract's pre-applied group. Glutathione level, activities of glutathione peroxidase, glutathione Stransferase and glutathione reductase were decreased in thyroxine treated group. But, they were increased in HJ extract's pre-applied group. These results suggest that in thyroxine-induced hyperthyroid rats HJhas an increase in the activities of oxygen free radical scavenging enzymes and inhibition of xanthine oxidase activities, and prevents lipid peroxidation.

The study is a comparative analysis of the differences in economic activities of two rural villages near the city. It is the general notion that rural villages near large cities lose the characteristics of traditional rural villages and change the areas with urban characteristics due to the influence of urbanization. The survey also showed that Munho 4-ri and Jeongbae 1-ri in Gyeonggi-do have urban characteristics, such as population growth, agricultural activity reduction and non-agricultural activity increase, and community activity reduction. However, they also found that there were important differences in the future development patterns of the two villages. In other words, the reasons and purposes of migration of people moving to the two villages, the differences in the system of economic activity in the villages, and the differences in community cooperation are emerging. Therefore, the study shows that policies to develop rural villages near cities need to be implemented differently based on the characteristics of those villages.

Vibration disturbances induced by the reaction wheels can severely degrade the performance of high precision payloads on board satellites with high pointing stability requirements. The unwanted disturbances produced by the reaction wheels are composed of fundamental harmonic disturbances due to the flywheel imbalance and sub/higher harmonic disturbances due to bearing irregularities, motor imperfections and so on. Because the wheel speed is constantly changed during the operation of a reaction wheel, the vibration disturbance induced by the reaction wheels can magnify the satellite vibration when the rotating frequency of wheel meets the natural frequency of satellite structure. In order to provide an effective isolation of the reaction wheel disturbances, isolation performance of a hybrid vibration isolator is investigated. In this paper, hybrid vibration isolator that combines passive and active components is developed and its hybrid isolation performance using notch filter control is evaluated in single-axis. The hybrid isolation performance using notch filter control show additional performance improvement compared to the results using only passive components.

In this paper, we introduce the appoaches that aim to improve user experience in mobile device by the use of multiple vibration signal feedback, conducted by Haptics and Virtual Reality laboratory at POSTECH. We introduce current progresses of our 'Vibrotactile flow using multiple vibration actuators' and 'Real-time dual-channel haptic music player.' The 'Vibrotactile flow using multiple vibration actuators' produces vibrotactile flow sensations by using multiple actuators and that improves the information transfer on mobile devices. The 'Real-time dual-channel haptic music player' generates vibrotactile sensation by transforming auditory signal, which improves the user experience of mobile devices. These approaches can be good examples to fulfill the demands of better information transfer capability and user experience on mobile devices.
