Changing demographics, changing lifestyles. An international group of architects designs the homes of the future in places diverse as USA, Japan, South America and Europe. These architecture are also challenging the traditional structure of the private house, as we know it. Many of these architects are reinterpreting the private house, challenging traditional notions of what makes house. Here, the interior and exterior surfaces are transformed into 'smart skins', which blur the distinction between the digital and the real and become a part of the daily life of the occupants. The smart house will make possible amazing things we though existed only in science fiction, guarding or welfare, guessing our moods and catering to our demands in music, movies, temperature and ambience. And new materials will further transform our living areas.

Being a symbolic image to let traditional 'mother wonlee' contents characters known widely, need to be made in a way that can deliver the powerful message of korea An-dong traditional local contents and the value of regent story. As for the contents character develope methods and the scope of the study, an theoretical study was conducted based on literature review, and, factor plus fiction field surveys, and the legend story and then an effect of character marketing on global contents with original identity. 'mother wonlee' pre-production plaining have been analysis with creative described based on the ancients features and the classification of ancient original characters, and the situation and the concept of An-dong local place. as a results this thesis is show up how to make up a main character develop processing and make a features design processing of the characters who different age and a scenes. as a conclusion is drawing about a 'Wonlee' and 'Eungtea' both main Character plaining processing and graphics; traditional face, all clothes, body proportion, etc. Also we trade to traditional patten with character planing. it will be a high value industry which facilitates a variety of industries in conjunction with marketing traditional source characters in global. Recognizing the value of traditional story main character design and graphics marketing and utilizing the value through various media will create infinite value, enabling the global marketing.

The Ubiquitous life is not a life style that exists in a science fiction or in a far distance future anymore. The Combination of electronic and physical space, this new type of space was created by the ubiquitous network system, and this system will offer us new life style. Also the pattern of our living will be changed by the information that has obtained from this ubiquitous network system. By offering a new way of communication from the ubiquitous surrounding, our life style such as shopping, medical treatment, banking, and working conditions and a notion such as the preference in a job title would have shifted. This study have arrived at the development of the high technology, in other words Ubiquitous age , I have considered the notion of home-network that have observed by the preceding investigators as well as the theoretical consideration of residential space in ubiquitous surrounding. After I look into the usages and examples of residential space in ubiquitous surrounding of today's society, I hope that this would be helpful for the design that strives for the comfortable living in this ubiquitous age.

About 6,000 rock properties obtained from laboratory tests are collected from various projects conducted in Korea Peninsular and the distribution of the properties such as uniaxial compressive strength, cohesion, kriction angle, tangential strength, Young's modulus, p-wave velocity and S-wave velocity are analysed and correlated each other. The empirical equations deduced with 84% of reliability would be useful for preliminary design of geo-structures.

A clutch hydraulic system for automotive manual transmissions transfers hydraulic pressure generated by driver's pedal manipulation to the clutch mechanism. The foot effort when the clutch pedal is pushed is different than that when the clutch is returned. The effort or load difference, called hysteresis, is caused by the friction produced between rubber seal and inner wall inside the hydraulic cylinder. This clutch pedal travel foot effort hysteresis is essential for a clutch hydraulic system design and analysis. The dynamic model for a clutch hydraulic system is developed and a simulation analysis is performed to estimate the fiction coefficient as a function of the cylinder pressure. The simulation result is then compared to the measurements obtained from a clutch hydraulic system tester to ensure the reliability of the dynamic model and the coefficients estimated. Also the estimated friction coefficients at various pressure values are compared to those reported by an independent study.

Recently, a neuro-fuzzy approach, a combination of neural networks and fuzzy reasoning, has been playing an important role in the motor control. In this paper, a novel method of fiction compensation using neuro-fuzzy architecture has been shown to significantly improve the performance of a DC motor system with nonlinear friction characteristics. The structure of the controller is the neuro-fuzzy network with the TS(Takagi-Sugeno) model. A back-propagation neural network based on a gradient descent algorithm is employed, and all of its parameters can be on-line trained. The performance of the proposed controller is compared with both a conventional neuro-controller and a PI controller.

In optical disk drives, one of commonly used pickup actuator is a Sliding and rotary type of pickup actuator which is cheaper than other pickup actuators and has simple assembly. However, it reported that non-linearity due to friction between a shaft and a sleeve had to be considerably analyzed in design and servo system in employing this type of pickup actuator. In this paper, this friction is modeled as a Coulomb's friction and the effect of friction is examined in the simulation. A digital servo system is applied to pickup actuator with friction in order to have good focusing servo. To enhance focusing servo performance using digital servo merit, frist PD-controller is applied to have fast response performance, second lead-lag compensator is applied to have stable focusing performance.

China's online games have been developed a decade, the online game development is very fast. The last monitoring from "gameScan$^{TM}$" shows that there are 6 local manufacturing MMORPG games in the top 20 in march 2010 of china.Through research top 4 MMORPG games, their graphic content is too similar. All of them are the subject of Chinese Martial-Arts and Chinese Mythology, the graphic design elements all from China's traditional culture. This phenomenon will be two defects, the first if the design follow the trend, it can reduce the risk of failure, but it'll lack of competitiveness also. The second is it can meet the needs of Chinese culture for the game players in china, but the complex Chinese mythology and the culture of Martial-Arts are not easy to be accepted for foreigners. There are many European and American games failed in China, because of the differences cultural, the Game players can't understand the history, religion and culture. so, we can get some experience from the successful game cases of Korea and Japan. Use of common cultural elements combined with some Chinese traditional culture to create a new fantasy world. And try some now contents about future or science fiction.

Structures with additional frictional damping system have strong nonlinearity that the dynamic behavior is highly affected. by the relative magnitude between frictional force and excitation load. In this study, normalized response spectra of the structures with non-dimensional friction force are obtained through nonlinear time history analyses of the mass-normalized single degree of freedom systems using 20 ground motion data recorded on rock site. The variation of the control performance of frictional damping system is investigated in terms of the dynamic load and the structural natural period, of which effects were not considered in the previous studies. Least square curve fitting equations are presented for describing those normalized response spectrum and optimal non-dimensional friction forces are obtained for controlling the peak displacement and absolute acceleration of the structure based on the derivative of the curve fitted design spectrum.
