  • After free trade, it is increasing to import crops, aquatic products, and livestock which are produce in a foreign land. But it is affect negatively to trust relationships and markets of Jeju's foods because of breaking it out that foreign productions exchange domestic. Therefore, this paper designed and implemented the Genuine Quotation system of Black pigs using UHF RFID. This system is developed for distinguishing spuriousness, then searching information of the product through EPC ONS in EPCIS to print within a screen. Moreover, this intuitional and efficient system is constructed by connecting various sensors and lights. It can be contributed income increase thorough the security for the quality authority of the agricultural & stockbreeding products with FCS, FCG Certificate and the genuine certificate of the black pig which is the one of most typical agricultural & stockbreeding products in the pure Green Province, Jeju.

  • A limitation of oxide cathode is the high current density, caused by low electrical conductivity of an emitter layer. This limitation can be overcome by increasing the conductivity, and uniform dispersion of Ni powder and pore agent could be achieved by using the screen-printing method. This new cathode has shown not only high current density reliability but also improved performance characteristics and as such given the name "Multi-Function cathode". It is expected to be a good replacement of the impregnated cathode.

  • Simulation tools are widely used for performance evaluation of newly proposed systems. However, many industrial simulation projects fail to attain the original goals ,especially when very complicated decision logics of the experienced operatorsare needed to be modeled. We propose a technique to overcome the oabstacles. In the proposed technique, complicated decision logics are not directly modeled but an interface for interactive input is provided in the model. While running the simulation model in concurrent animation mode, whenever operator's decisions are needed an interfce screen is displayed for operator's decisions. The operator then makes decisions using the information which is provided by the animation proces itself. This technique was successfully applied to an industrial simulation projects in which alternatives were evaluated for increasingthe color lot size of car print shop.

  • Carbon nanotube (CNT) cathodes having a trench structure similar to the structure of the gated triodetype cathode were successfully fabricated by a screenprinting method with multi-walled carbon nanotubes. We observed that a liquid method not only readily removes the organic residues on the CNT films, but also satisfactorily protrudes the CNTs out of the electrode surface. The CNT cathodes prepared by the liquid method showed a turned-on field of $1.4\;V/{\mu}m$. The emission current density of them was about $3.1\;mA/cm^2$ at the electric field of $3\; V/{\mu}m$. The liquid method appears to be a promising surface treatment of CNT cathode for gated triode-type FEDs applications.

  • The burn-out technique is used to result in the velvet cloth being patterned in open and solid areas by carbonize the cellulose fiber. It is examined how to burn out the cellulose part of the velvet without damage of the other part. The print paste indalca solution is mixed with sodium hydrogensulfate and lycerine and then screen-printed on the back side of the velvet. The effects of process conditions such as concentration of sodium hydrogensulfate dry heat fixation temperature and time pull no. and glycerine contents on the properties of ground farics were investigated. The yellowness index and the breaking load of silk ground fabrics afected by the process conditions especially concentration of sodium hydrogensulfate dry heat fixation temperature.

  • Most people in our society use credit card instead of cash or check, so credit card is very important economic method. Credit card supposed to be safe, but hackers hack credit card for illegal deal. Also hackers make fake credit card and issue fake credit card to other people. In this thesis it will study and analyze damage case for safe credit card deal. It will use safe credit card system to insert variety of information and data of using pattern in artificial intelligence network, so print out the possibility of risk and monitor the risk of credit card user's deal pattern, so if one of user's pattern is different than normal pattern, it will pop up message in consultant's screen. This thesis will study and suggest way of prevent from illegal deal and user friendly credit card checking system.

  • A study on thermal properties for a single-layer metal and two-layer composites was investigated for the heat-sink application. For the single-layer metal, an aluminum alloy (Al6061) was selected. A screen printed aluminum nitride (AlN) layer on the Al6061 substrate was chosen for the two-layer composites. The thermal conductivity of the sample was determined from the thermal diffusivity measured by the light flash analysis (LFA), specific heat and density. Measured thermal property values were compared to calculated values using the data from the references. The thermal conductivity of composites with screen printed AlN layer on the Al6061 substrate decreased linearly with increasing the thickness of AlN layer. Measured values of the thermal conductivity for composites with $53{\mu}m$ and $163{\mu}m$ thick AlN layers were $114.1W/m{\cdot}K$ and $72.3W/m{\cdot}K$, respectively. In particular, the thermal conductivity of the screen-printed AlN layer was demonstrated by appling the rule of mixture in view point of thermal resistivity. Measured values of the thermal conductivity for AlN layers with the thickness of $53{\mu}m$ and $163{\mu}m$ showed $9.35W/m{\cdot}K$ and $12.40W/m{\cdot}K$, respectively.

  • In recent, a digital x-ray detector attracted worldwide attention and there are many studies to commercialize. There are two methods in digital x-ray detector. This method is an Indirect method and Direct method. This study is to see the differences between the digital x-ray detector based on a-Se used in the existing indirect conversion method and an x-ray conversion material that has better SNR(Signal-to-noise ratio) and property than the a-Se. To solve the problem that is difficult to make a large area film using Screen-Print method, we used a Screen-Print method. In this study, we used a polyclystal $HgI_2$ as x-ray conversion material and a sample thickness is $150{\mu}m$ and an area is $3cm{\times}3cm$. ITO(Indium-Tin-Oxide) electrode was used as top electrode using a Magnetron Sputtering System and each area is $3cm{\times}3cm$, $2cm{\times}2cm$ and $1cm{\times}1cm$ and then we evaluated darkcurrent, sensitivity and SNR of the $HgI_2$ film are measured, then we evaluated the electrical properties. And we used a current integration mode when I-V test. This experiment shows that the sensitivity increases in accordance with the area of the electrode but the SNR is decreased because of the high darkcurrent. Through fabricating of various thicknesses and optimal electrodes, we will optimize SNR in the future work.

  • TYME is an interactive typography program based on the ephemeral nature of time. It is a text based poetic tool, built with Processing. This project is presented as a performance that utilizes a computer with a display screen, a projector, and speakers. As the user types, white characters appear, flow on the score on the screen and trigger jazz sounds, then characters disappear into black space in several seconds on the screen like smoke. Typography from this invented instrument is evocative and wistful, and allows the user to associate with ephemeral time. While typing the characters as though playing an instrument at intervals of time, the user can freeze the motion and print out or save otherwise fleeting moment with a button. I intend to contain both characteristics: the amorphous shape of smoke and the elusive attribute of smoke for the expression of intangible and ephemeral time. Every alphabetic shape is derived from the video dips that I shot of smoke. The resulting alphabetic images are then programmed using the Processing scripting language and which can then be typed on the screen with a keyboard. TYME could be a model as a project that reflects the unfixed quality of digital typography, and as a design approach for interactive expressive typography by scripting code. This project also represents the characteristics of typographic play, which can be realized in an computational environment like this model.
