This study researched the status and prospect of a natural dye program in Gyeongsang region that focused on private centers with sufficient infrastructure and abundant human resources were available for natural dyes. The entire site for metropolitan cities that have difficulty in securing the land are limited (as well as smaller) because they are closer to the city; in addition, they do not own the drying house and the agricultural land for natural dyes. It is understood that the one-time program of all centers researched help to promote and maintain the centers rather than generating profit; in addition, it is shown that Jun - Aug (summer) is preferred over Dec - Feb (winter). This program uses natural indigo; consequently, natural dye program for hobby and education is operated when it is required because the number of participants are low in most cases, Persimmon Juice is used for the dyeing raw materials. Programs in operation are often outsourced with other institutes registered under private certification system; therefore, many cases of starting business are found in the institutes operating programs directly after obtaining the certification. Their plans do not allow for investment in facility such as enlargement of experience center and prospect of program; in addition, business value is generally bright for business strategies that include an exhibition shop for natural dye products and program development.

Priming of seeds in 150 mM KCI at $10^{\circ}C$ for 6 days was most effective in increasing germination rate and shortening germination time. Germination rate of primed seeds was increased to 96% which is about 14% higher than that of non-primed seeds. Germination temperature for better priming effects from primed onion seeds was 10 to $15^{\circ}C$ which is relatively lower than that of normal germination temperature of $20^{\circ}C$. Drying primed seeds at $20^{\circ}C$ for 5 hours resulted in best priming effects.

The purpose of this study is to establish the one serving size of Korean Processed Food. Defining the one serving size is very important for nutrition labeling and foodservice operation, because the one serving size is used to set up a proper portion by each foodservice operation. The basic data of 200 items were collected through three methods. Searching many cookbooks, exploring the commercial and noncommercial foodservices -6 industrial foodservices, 100 nationwide elementary school foodservice recipes analysis, and 3 hospital foodservice systems as the samples - moreover, experimental cooking and sensory evaluation by trained panels were conducted to assess quantity preference of selected food items. All data were rearranged through food type, that is, main dish, side dish, dessert and health food. One serving sizes of processed foods showed wide variety according to the different menus that include selected food items. Therefore, means and ranges of serving size by three research methods were presented item by item. The results obtained were: 1. The Korean Processed Foods were dried and sugar adding and soused foods, and many of them used the natual processing methods. 2. There were wide varieties in the classification of main dishes, but many of them were cereals, noodles, and sugar products. One serving size of noodles were around $50{\sim}100\;g$, cereals were $20{\sim}40\;g$, which means the one serving size can be differenciated by the food usage. 3. According to the Food classification of side dishes, many of them were as following; natural dried foods, processed fish products, salted or sugar added foods, seasoned foods and sugar products. Moreover the Types of cooking in side dishes were almost culinary vegetables, teas, health foods and condiments, and soused fish products. 4. About desserts, they were almost teas and sugars, and the Types of cooking were teas, health foods and seasonings. 5. We can conclude that almost Korean Processed foods used the drying and soused processing methods for long-time preservation, but it can make the higher content of any special elements, such as sodium or carbohydrates.

The doma (cutting board) is an essential kitchen utensil. The general doma used at present is not sultable for cutting kimchi-like juicy foods, because It is a nat flat structure. Kimchi juice contains vitamins, organle acids, and lactic acid bacteria, and inhibits Oxidation of flavor of kimchi. In addition, if the juice flows down on the doma during cutting the doma work-table and kimchi bottom is contaminated. In this studies a new type of doma for kimchi. was made in order to minimize the Juice Iou during cutting. This new one baa a two-dimensional function of low due to length slope face and slanted gutter of width. No this new type has been developed worldwide, as far as the present writer is aware. The new one has various effectivenesses: minimixing loss of kimchi juice and contamination of doma work-table and kitchen bottom by kimchi juice, saving water and time to water contaminated cutting board, work-table and diahtowel (hangju). preventing round from falling down frorr doma duing cutting, decreasing damage of cutting the user's finger, cutting by the fixed size and shape. Draining and drying is easy and it is convenient to cut all juicy food.

Low-viscosity alkoxysilanes that polymerize into the porous network of decayed stone by a sol-gel process are widely used as stone consolidants. During drying, the gel network contracts due to capillary pressure generated by solvent evaporation. We have prepared tetraethoxysilane mixed solution containing methyltrisilane, ethyl trisilane and (3-glycidyloxypropyl)trimethoxysilane having epoxy ring in order to reduce the shrinkage happened inside the stone porous structure during the gel formation. Mixed solutions were applied into sandstone and granites and characterized by FT-IR, SEM. The gelation time, water uptake, contact angles were measured and compared with those of the commercial stone conservation materials.

This study examined 12 types of towels with differing fabric material, function, quality, printing, pile length, twist, etc. from a towel company which manufactures and distributes products domestically. After 3 months of use by consumers, a consumer satisfaction survey was administered and results analyzed. Four types of towels were assigned to each group and the towels were used every day for 3 months. Participant feelings after using the towel for the first time and after using it for three months were investigated. The questionnaire consisted of 26 questions on a 5-point Licket-type scale. The first 13 questions measured perceptions of absorption, touch, fine fiber loss, contamination, deformation, drying speed, and design. Other questions compared differences between the two towel types in terms of their material, function, quality, printing, pile length, and degree of twisting. Results showed that, with regards to weight, consumers preferred towels between 130~150g and a thickness of around 1.7~1.8mm. The bamboo towel was considered superior to the cotton towel in terms of sense of touch and did not happen linter after washing. The antibacterial towel was considered better than the cotton towel in terms of absorption but in terms of contamination, participants felt the antibacterial towel became dirty more easily than the cotton towel. We thought that it might be influence of the color of towel. Low-quality towels became stiffer and misshapen more easily than higher-quality towels. But the study showed that the consumers did not perceive significant differences in the towels' quality. Printed towels became thinner and their color changed more with washing. The consumers preferred the design of jacquard towels to printed towels. Towels with short piles was happened more linter than the towel with long pile after washing. Non-twisted towel were better than the highly-twisted towel in terms of sense of touch and absorption but the non-twisted towel happened more linter after washing and became dirty more easily.

Two PU flame-retardant coatings, 2,3-DBPO/N-l00 (DBPON) and 2,3-DBPO/IL (DBPOI), were prepared by curing 2,3-dibromo modified polyester (2,3-DBPO) with isocyanate curing agent Desmodur N-l00 (or Desmodur IL) at room temperature. The physical properties and flame-retardancy of the two coatings were tested and compared. As a result, the pot-life, yellowness index, lightness index difference, $60^{\circ}$ specular gloss, cross-hatch adhesion, viscosity, and accelerated weathering resistance of DBPON were better than those of DBPOI; the fineness of grind of the two coatings were the same; and the drying time, hardness, and abrasion resistance of DBPOI were better than those of DBPON. The flame retardancy of the flame-retardant coatings increased with the content of the flame retarding component, 2,3-dibromopropanoic acid (2,3-DBP); and the LOI values of the two coatings were in a range of $27{\sim}29%$ when the content of 2,3-DBP was 30wt%.

In order to prepare high-solid coatings, acrylic resins, HSCs [poly (EA/EMA/2-HEMA/CLA)] that contain 90% solid, were synthesized by copolymerization of ethyl acrylate (EA), ethyl methacrylate (EMA), 2-hydroxyethyl methacrylate (2-HEMA) and caprolactone acrylate (CLA). The high-solid coatings named as CHSCs (HSCs/HDI-trimer) were prepared by the curing reaction between the acrylic resins containing 90% solid contents and the isocyanates (HDI-trimer) curing agent room temperature. The curing behavior and various properties were examined on the film coated with the both high-solid coatings. The glass transition temperatures $(T_g)$ of CHSCs increased proportionally with increasing the predicted $T_g$ value by Fox equation, and had nothing to do with the solid contents. The prepared film showed good properties for $60^{\circ}$ specular gloss, impact resistance, cross-hatch adhesion and heat resistance, and bad properties for pencil hardness, drying time, and pot-life. Among the film properties, the heat resistance was very excellent and could be explained by the introduction of functional monomers of CLA.
