Barrier ribs for PDP(plasma display panel) are commonly utilized to have uniform height and width and to prevent opical crosstalk between adjacent cells. The requirements for such barrier ribs are uniform height and shape, low outgassing rate and low porosity, high aspect ratio, and fine resolution. In this study, we are studied about that to make efficiency of material and high quality barrier ribs for PDP. As a result, could got high barrier ribs of $140{\mu}m$ evenly in 1th phenomenon using watersoluble UV curing resin and know that flatness of upper part is also very good.

With the development of many display technologies currently applied to them in the field of printed electronics, there have been many researches that high resolution printing for thin and uniform pattern. In this paper, printing ink flow properties in the reverse offset mechanism were simulated. The aim of this research is to expect the ink flow behavior between cliches to make fine pattern by a printing technique which is a reverse offset. The simulation results show that almost the same as the experiments and the flow behavior according to the ink film thickness and printing pressure changes could be expected.

This paper seeks to find out the policies of management and layout of middle school rooms for the community people's use. This paper surveys community's needs with respect to both the use of school rooms before, during, and after classes and preferences of use of school rooms. This paper adopts two experimental case studies to find out the models. It uses t-test analysis of the statistics to find out community people's preferences for the use of school rooms between two communities in an urban area, and uses simple and multiple regression analyses to develop models concerning community people's uses of school rooms before, during, and after classes. It also uses cluster analysis to find out the cluster among community people's preference of school rooms. It found, first, that community people's use of school rooms after class can be influenced by the uses of a play ground, a music classroom, an audio visual classroom, and a gymnasium. The use during regular classes is related to the uses of the fine arts classroom, a general classroom, a home economics classroom, a gymnasium, and a playground. The use before class is affected by the uses of a fine arts classroom, a playground, and a library. It also found that, with respect to community people's preferential use of school rooms, the rooms can be clustered as a cluster of laboratories such as a general classroom, a music room, a fine arts classroom, a science classroom, a home economics classroom, and a technique classroom, a cluster of athletic areas such as a gymnasium and a playground, and a cluster of supporting facilities such as a library, an audio visual classroom, and a computer classroom. Those clusters can also be clustered in more detail, i. e., that both a general classroom and playground can be apart from a cluster of laboratories or a cluster of supporting facilities; that an audio visual classroom can be fostered into a cluster with a home economics affairs classroom and a technique classroom. Finally this paper suggests policies of management and layout of school rooms.

A new photochromic spiroxazine dye having a pyridinium s-triazine moiety has been prepared. It shows a reversible photochemical color change from colorless to reddish-purple in ethanol solution. In ethanol solution the half life time of the open form was 150sec, which was shortened by raising temperature. Silica-immobilized spiroxazine(6). Fine power of silica-immobilized spiroxazine was changed intensely blue from colorless by U.V. light or sunlight.

In screen printing process, printing are streching screen meshs of an angle of 45deg. This angle need much more screen mesh`s quantity of 15% than 22.5deg. To seach mesh angles have affect on reproducting fine line pattern, we modeled the expecting image according to screen angles change and reconfirmed it`s useful and valid from experimentation.

Arts is the expression of reasoning and conscious life of human and arouse human the concept of existence, utmost emotion and excellent thoughts. Also it makes humans life very abundant. I make it come first to get rid of the art thirst on the opposite sight of technical one for hair as on part of humans body. Next purpose is that to confirm the esthetic value of 'hair arts' by solidify the academic ground of beauty arts through creating 'hair arts' works and learning and make the direction for the beauty industry and education of the next generation. In this study I investigated the Greek myth and the hair styles of ancient Greek Goddesses. On the basis of that symbols I elaborated hair formative works made of metal and studied, analyzed and displayed that. Work No.1 'aphne' pictures the second of changing into a laurel tree avoiding the love. Secondly 'Muse Erato' was exhibited the peaceful figure that have enough the fine melodies. 'Leda' brings out the feature of Leda resembling a swan and the fourth piece, 'Eos' conveys the brilliant and mystery of dawn. So this study conducted based on the concept of practical hair and have made efforts to be close to theoretical manufacturing research needed at making hair arts works and academic one needed at organic design composition for pioneering new field, 'art hair.' I hope these 'hair arts' works make creativity of the practise hair alive. It will be very thankful to me if this study can help even though slightly for splendid beauty arts to make its status firm as a one part of arts, and there are following studies.

Gravure off-set printing recently is used in electronics display market. This method has advantages of mass production and high printing speed. It is also fine pattern can be implemented. We have manufactured low-curable conductive Ag pastes for gravure off-set printing. When printing, the pastes be used different silver powder shape because of the printing characteristics. The pastes were prepared with silver powder by silver powder shape and size, epoxy resin, solvent and homogenized on a standard three-roll mill. And the pastes exhibited a shear-thinning flow at viscosity profile. Moreover the adhesive strength and resistivity of silver film had a good characteristics. With the manufactured paste in this study, touch panel had is manufactured and it had $4{\times}10-5{\Omega}.cm$.

The present study investigated regional and sex differences in knowledge, perception, cognition and behavior of fine-dust protective masks for periods of high concentration of fine dust in Korea. A total of 2,012 adults from seven provinces responded to the questionnaire. The results (all p<.05) showed that 78% of respondents considered pollution from China to be the greatest contributor of fine dust. Seoul and Gyeonggi residents more frequently checked fine dust forecasts than other provinces and consulted their smartphone applications to do so more than other residents. Jeju, Gwangwon, and Jeonla residents had less knowledge of KF 80, 94, and 99 masks than residents of other provinces. Gwangwon and Jeju residents had less trust in the effectiveness of protective masks than other residents. Females perceived themselves as unhealthier respiratory, more frequently checked the concentration of fine dust, trusted more the effectiveness of masks, and more frequently wore masks, compared to male respondents. Those who self-identified their respiratory function as poor, more frequently checked fine dust forecasting, and had greater knowledge of masks, which resulted in greater trust in the protective function of masks, and finally had higher wear frequency of masks for days with high concentrations of fine dust.

The recent spotlight on electronic touch-screen display, a rapid breakthrough in the information society is evolving. Touch panel input device such as a keyboard or mouse without the use of, the on-screen character or a specific location or object on the person's hand touches a particular feature to identify the location of a panel is to be handled. The touch screen on the touch panel is used in the Ag paste is used mostly for low-curable paste. The thermal-curing paste according to the drying process of thermal energy consumption and improve the working environment of organic solvents have problems. In this study, Ag paste used in the non-thermal curing friendly and cost-effective UV curable paste was prepared. Current commercially available thermal-curable binder, was used instead of the flow characteristics of UV-curable oligomers and monomers with functional groups to give a single conductive Ag paste with the addition of a pattern could be formed. Ag paste as a result, thermal-curing adhesive, hardness, resistance and excellent reproduction of fine patterns and was available with screen printing environmentally friendly could see its potential as a patterning technology.
