According as gradually increasing the demand for eco-friendly at the printing process, it has been progressed fairly development. Especially, the inks are used by soy oil beginning of ink industry for preventing environment, it is possible to make eco-friendly inks with vegetable ester. So it is not necessary to use petroleum-based solvents at all for preventing environment. These eco-friendly inks have a benefits they are able to use the renewable resource. But basically vegetable oils have that reduce the VOC(Volatile Organic Compound) and high viscosity, high solubility properties. So if the vegetable oils use in the ink, set off problem occur on the paper because of slow drying time. In case of vegetable ester, it has similar the molecular weight and kinetic viscosity with hydrocarbon solvent, it is able to control the power of dilution about the resin. So, it has benefit that solve the problem of the existing eco-friendly inks. In this study, different types of ester were made by six types of vegetable oils and used ester in the varnishes and inks properties are comparison with hydrocarbon solvent based ink. By considering the intrinsic properties of vegetable oil, ester used to analyze the changes in ink properties, using ester varnish is applied to study the rheology characteristics and emulsification with inks.

This research attempts to analyze the effect of printed-saving coupons distributed by major discount store on consumer purchasing intention. Those consumers having used printed-saving coupon in major discount store in Daejeon were selected as respondents. 121 copies were retreated from 150 questionnaires. For data analysis, frequency analysis for respondents' characteristics, Cronbach's alpha for reliability of analysis, and X2 test of multi-regression analysis for testing hypothesis were utilized. The result of analysis shows 1) the way of using coupon is respectively different according to sex, age group, marital status, term of coupon, and the number of using coupon; 2) Attributes of coupon partially influence on purchasing intention of consumers. Only shopping cost cutting is insignificant, while keeping convenience, impulse buying, scheduled purchasing are significant. The most effective variable is scheduled purchasing, keeping convenience, and impulse buying influence on purchasing intension of consumers. Therefore, offering printed-coupon by major discount store is useful tool to induce consumers to planned purchasing.

Polyacrylate dispersion(emulsion) as adhesive material was superior in quality such as preservation characteristics and reversibility. The tapes for repairing archival documents manufactured with four different types of formulation resulted in pH 7～8.8, soluble solid 50～52%, and viscosity 1,300～2,500 cps. Sample 4 of those was most excellent. Probably, sample 4 included inorganic materials such as MgO, silica gel, and zeolite. For selecting carrier of tape, tracing papers, were applied for manufacturing tapes and tested for adhesive strength and peel strength. Adhesive strength of tracing papers, was 3.1～3.8(N/10mm), 2.2～2.8(N/10mm), and 1.7-2.3(N/10mm), respectively. Peel strength was similar in all samples. To determine characteristic of conservation to the selected carriers, stability of deterioration was examined at conditions of 105℃ and 80℃ 65% for 7 days.

The inorganic powder EL lamp was made by screen printing technique with a phosphor ink and a dielectric ink. Value of color coordinates X and Y increased under the condition of supplying driving power to the inorganic powder EL lamp and changing voltage with constant frequency. When frequency was changed under the constant voltage, value of color coordinates X and Y were decreased with increasing frequency. However, level of change of color coordinates X was different from color coordinates Y. When voltage was increased under constant frequency, changing degree of color coordinates X and Y shows similarity. But under the constant voltage with changing frequency, color coordinates X and Y were differently changed that degree of change of color coordinates Y showed five times more than that of color coordinates X. As increasing thickness of phosphor ink and dielectric ink, level of voltage and frequency, color coordinates X and Y were slightly changed. According to the thickness of phosphor ink and dielectric ink, and level of voltage and frequency, color coordinate of color light was changed. Frequency was most important element influencing on the change of color coordinate.

This study is Long term preservation measures which is closely related to preserving paper records, record condition evaluation, preservation measure and is conducted as follows. As for Means to Evaluate the Deterioration and Damaged Conditions of Records, research and analysis has been made on the contamination and deterioration examples such as damage, dry, stapler, metal, contamination, acidification which are the characteristics of paper record damage types. The of Paper record is one of the key procedures to evaluate the record material and its physi-chemical status in many criteria and to suggest the best preservation method. Between 1970 and 2000, the main record materials was fine paper and OMR paper along with partly newspaper and coarse paper, whereas the main recording material was ball point pen. Overall damage and deterioration status is, for record materials between 1940 and 1960, high deterioration was found and in urgent need for preservation measure and more damages are caused by tapes, staplers and metals. As for records after 1970, there is light deterioration but needs preservation process. There are approximately 3 million records produces before 2000, and assuming that there are 30 pages per record and that 30% has been damaged or deteriorated, 27 million pages are subject to preservation process. Among damaged or deteriorated records, there are large number of records impossible to go through deacidification process so manual preservation and restoration process is necessary as well. Securing manpower having preservation and restoration skills as well as preservation equipment(deacidification process, preservation and restoration) is in urgent need.

A research framework and hypothesis were established for analysing layout-factors of bus wrapping which influence on brand attitude. 130 questionnaire were distributed and 123 copies were retreated at metropolitan area. SPSS 12.0 was used for frequency analysis, factor analysis, and reliability analysis. For testing hypothesis multi-regression analysis were utilized. Attention, readability, explicitness, formativeness, creativity are partially significant to establish brand attitude. Attention and readability are insignificant, while explicitness, formativeness, creativity are significant to establish brand attitude. The most effective independent variables are creativity, and explicitness and formativeness are followed. In particular sensual, original, fresh layout of bus wrapping are highly significant.
