In this research, an Electronic White Board Control System is developed that stores and prints the data written on the white board. This control system is constructed using an embedded single board PC, whose function is the acquisition(from CCD image sensor system), processing and storing of the data on the screen. The properties of this system are as follows: 1. The system is able to move the screen on the right and left. 2. The system is able to output the data written on the screen to a connected printer. 3. The system is controlled by an external remote PC connected to the system by serial line as well as by the keys on the control panel. The data written on the screen can be sent to the external PC and then can be modified and stored...

Recently, studies of 3D printing methods have been working in various applications. For example, the powder base method laminates the prints by using a binding or laser sintering method. However, the draw back of this method is that the post process is time consuming and does not allow for parts to be rapidly manufactured. The binding method requires the post process while the time required for the post process is longer than the manufacturing time. This paper proposes a UV curing binding method with an integrated piezo printing head system. The optimization of an arbitrary waveform generation for the control of a UV curable resin droplet was researched, in addition to developed optimized UV curing processes in multi nozzle ink jet heads.

The history of architectural acoustics is a part of history of human being getting together for both politics and entertainments, is also a part of the history of nobility pursuing hearing enjoyments, is still a part history of scientists deeply understanding the concept of "just for people", and as well as is a part history ceaselessly driven by the musicians to find their real hearts through music. The history of architectural acoustics explains not only the acoustic knowledge developments in architectural design, but also the unity on contradictory of both the science and the arts, both the technology and the culture, both the sense and sense organ. The history of architectural acoustics prints the interactions between the mankind and the nature, between the mankind and themselves, between the mankind and their souls, in which course people understand their feelings more deeply and deeply. This paper discusses the brief history of architectural acoustic in China from the ancient drama stages to grand theaters in 20 century, even up to nowadays, including some most important buildings and events as well.

We report optical spectra of underdoped $BaFe_{1.89}Co_{0.11}As_2$ that hosts both of magnetic and superconducting orders. The temperature dependent evolution of optical conductivity shows finger prints of the magnetic order and the s-wave nature of the superconducting gaps. Careful inspection on the superconducting state reveals that the two orders compete but coexist in the ground state.

Film has been used widely since Auguste and Louis Lumiere hold the first private screening in 1895. Star Wars Episode II: Attack of the Clones directed by George Lucas released on May 16, was the first motion picture both to be shot completely on a high definition digital 24-frame system and to be projected by digital projectors. Its success showed us that the digital cinema era is imminent. Digital Cinema will enable the studios and movie distributors to low the expenses of making and delivering film prints and dissemination of it can put the entire digital cinema ecosystem in great jeopardy. Therefore DRM and other security policies are used for digital cinema content protection. In this paper it will be discussed how the digital cinema platform can package (encooe & encrypt), transport, and project the digital cinema contents safely.

American trendy casual styles can be characterized as fitted to body and rendering sexy and fashionable images and now very popular in Korea. This paper aims to identify diffusion channels of Amreican trendy casual style among Korean market and the characteristics of imitation for American trendy casual styles made by Korean casual brands. American trendy casual style was introduced and diffused mainly through 3 channels: American films and TV dramas, on-line communities, on-line shopping mall speciallized for purchasing American apparel brands. Some of American celebrities became fashion ikons and played critical roles in diffusing American trendy styles. After searching websites and fashion magazines and visiting brand stores, several Korean casual brands imitated the styles of American trendy casual brands and the scope of imitation was vast across items. Imitation was found mainly among T-shirts,jacket, jumper, pants, skirt and accessaries. Also imitation was found in almost every aspects of clothes such as shape, sihlouette, color, prints and stitching, belt, and drawstring.

S. Z. Wang, B. Y. Li, Z. M. Gao and K. Iseki proved some fixed point theorems on expansion mappings, which correspond some contractive mappings. In a recent paper, B. E. Rhoades generalized the results for in of mappings. In this paper, we obtain the following theorem, which generalizes the result of B. E. Rhoades. THEOREM. Let A, B, S and T be mappings from a complete metric space (X, d) into itself satisfying the following conditions: (1) ${\Phi}$(d(A$\chi$, By))$\geq$d(Sx, Ty) holds for all x and y in X, where ${\Phi}$ : R$\^$+/ \longrightarrowR$\^$+/ is non-decreasing, uppersemicontinuous and ${\Phi}$(t) < t for each t > 0, (2) A and B are surjective, (3) one of A, B, S and T is continuous, and (4) the pairs A, S and B, T are compatible. Then A, B, S and T have a unique common fixed point in X.

This paper proposes a separation of mixed signals by using the robust independent component analysis(RICA) based on neural networks. RICA is based on the temporal correlations and the second order statistics of signal. This method e is applied for improving the analysis rate and speed in which the sources have very small or zero kurtosis. The proposed method has been applied for separating the 10 mixed finger prints of $256{\times}256$-pixel and the 4 mixed images of $512{\times}512$-pixel, respectively. The simulation results show that RICA has the separating rate and speed better than those using the conventional FP algorithm based on Newton method.

A clothing design preference & clothing satisfactions(a general satisfaction, fitness) was studied for women 55 years and older. The major results are as followings. In view of a clothing design preference, 1) Styles of outdoor clothes for spring-fall : ① Two-pieces ② Blouse(Sweater) & Slacks ③Blouse(Sweater) & Skirts. 2) Colors of clothes for seasons: (Spring - Pink, Light yellow, beige), (Summer - Light blue, Blue, Light green), (Fall - Brown, Red purple, Beige), (Winter - Black, Brown, Gray). 3) Fabric prints ; ① Unicolor without print ② Geometric print ③ Traditional print. 4) Kinds of textiles : ① Easy Laundriability ② A style of dressing ③ Uncrumple. In view of clothing satisfactions for ready made clothes, they have unsatisfactory trends as following orders. 1) Considering a general satisfaction : ① Clothing which go with oneself ② Fitness ③ Matching with other clothes. 2) Considering fitness for clothes : ① Sleve length ② Shoulder width ③ Length in Blouse (Sweater) & Jacket, ① Length ② Waist ③ Girth of hip (under abdomen) in slacks (skirts).
