Jikji, Memory of the World of UNESCO, the world's oldest extant movable metal print book, is a cultural heritage to give motivation for IT power of Korea. Although the cultural value of Jikji is understood in Korea, the value of cultural assets is not satisfactory and the commercialization is not sufficient. Furthermore, most Jikji product designs on the market are simple and limited mainly for the old generation. The purpose of this study is to design fashion-cultural products suitable for young people who will be responsible for this cultural inheritance. The methods of this study were to make the design development through literature research and a case study for Jikji products on the market. For developing the products suitable for young people, 308 university students in Chungju were surveyed. To express end products, computer graphic program, Illustrator CS5, was used. The results of this study showed that the products on the market were not targeted for use by young people. The younger generations want modern and interesting design. Among the 8 design motives that are planned for design development, the most preferred motive numbers, 3, 7, and 8, were used. Design items, such as scarf, wallet and t-shirts, were selected by the result of survey and 3 scarves, 4 wallets, 3 t-shirts, a total of 30 items were developed. The designed products in this study can inform the cultural resource of Korea and contribute to raise the cultural value if they are commercialized.

This study analyzed the failure cases of new products for relative benefits among various factors related to the characteristics of innovation, which is an important factor in the consumer persuasion process among Rogers (1995)'s innovation diffusion theory. This is because relative profits are the most influential factor in consumers' intention to adopt among the characteristics of various innovative products (Holak and Lenmann, 1990). As a result of analyzing the failure cases of new products of six companies, these products lacked relative profits for existing products in common. Relative profits are factors that are measured in the economic sense or are measured by social advantages, convenience, and satisfaction, and are the most important factors compared to other factors such as suitability, complexity, observability, and applicability. In the end, it was found that relative profits compared to existing products are an important success factor in persuading consumers of new products.

The reduced production of domestic cosmetics in 2003, compared to last 5 years shows the recession of cosmetics industry. Under this situation, there has been reorganization on the domestic cosmetic market that low-end cosmetic .products become a trend due to the fact that major cosmetic companies also focus on low-end market since the last half year of 2004. However, it does not seem to be a temporal fashion that the extremely low-end cosmetics had an impact wavelength on cosmetics market. It has important meaning for the brand product strategy. This research focused on analysis of market situation and strategy through investigation of requirement and satisfaction on extremely low-end cosmetics in order to keep and improve it, which stimulated depressed cosmetic market.

This study suggests designs for fashion-cultural products that can communicate the uniqueness of Korean traditional culture. To this end, motives and printing patterns were created based on the formative beauty of traditional sewing crafts. A literature review was completed to identify characteristics of Korean traditional sewing, and the motives were developed through Adobe Illustrator CS4 and Adobe Photoshop CS4. Those motives were applied to handkerchiefs, neckties, pouches, and handbags. The sewing crafts used in this study included thimbles, bobbins, and chumoni (a Korean traditional pouch). The motives were produced in a manner that best exemplified the unique formative beauty of the sewing crafts while also presenting modern images of the crafts. The motives from thimbles reflected the lateral side of their originals, while the motives from bobbins adopted fan- or rectangular-shaped bobbins. The motives from chumoni were based on Duruchumoni and Guichumoni. A total of 12 motives were developed, and a total of 36 textile designs were suggested based on those motives. A total of 42 designs for fashion-cultural products, including handkerchiefs, neckties, pouches and handbags, were developed. Among them, motives applied to handkerchiefs were expanded to apply to scarfs, as well.

Remanufacturing is a process of recovering end-of-life products into serviceable parts for producing new products. Due to the limited supply of recovery cores to remanufacture, a remanufacturing firm also needs to produce or procure new parts for fulfilling the demand. This paper is targeted for solving the problem of determining the optimal amount of newly produced and remanufacturing parts, which is called production and remanufacturing planning (PRP) problem, under uncertain supply of recovery cores. The new production mitigates the risk of insufficient core supply while it takes more costs than the remanufacturing. The PRP model in this paper also considers disassemble-to-order (DTO) environment, in which multiple kinds of parts are remanufactured from multiple products on order of the parts. Whereas existing studies presents only heuristic solutions for DTO remanufacturing, this paper provides an exact solution for this problem and analytical sensitivity of the involved cost parameters, adopting multi-dimensional newsvendor modeling and stochastic linear programming techniques. The result shows that production and remanufacturing plans for multiple products are mutually dependent, and a change of cost parameters involved in only one part is propagated to all other parts.

The recycling cell formation problem means that disposal products me classified into recycling part families using group technology in their end of life phase. Disposal products have the uncertainties of product status by usage influences during product use phase and recycling cells are formed design, process and usage attributes. In order to treat the uncertainties, fuzzy set theory and fuzzy logic-based neural network model are applied to recycling cell formation problem far disposal products. In this paper, a heuristic approach fuzzy ART neural network is suggested. The modified fuzzy ART neural network is shown that it has a great efficiency and give an extension for systematically generating alternative solutions in the recycling cell formation problem. We present the results of this approach applied to disposal refrigerators and the comparison of performances between other algorithms. This paper introduced a procedure which integrates economic and environmental factors into the disassembly of disposal products for recycling in recycling cells. A qualitative method of disassembly analysis is developed and its ai is to improve the efficiency of the disassembly and to generated an optimal disassembly which maximize profits and minimize environmental impact. Three criteria established to reduce the search space and facilitate recycling opportunities.

Moisture loss of fresh fruits and vegetables is a main cause of deterioration. It resulted not only in the direct quantitative loss, but also in change in appearance, texture and nutrition. To reduce the loss of moisture content during the distribution in the market, fresh products are packaged using plastic films. But, most of the fresh products are packaged manually in Korea. In order to minimize the labor requirement, the packaging machine for fruits and vegetables was developed and tested. Prototype was composed of film feeding unit, bag former, products feeding conveyor, film feeding roller, center sealer, end sealer and discharge conveyor. Green peppers, carrots and perilla leaves were tested with prototype. Prototype could pack 1780, 1390, 1780 bags per hour at the feeding speed of 0.08m/s respectively and 2250, 1810, 2640bags per hour at the feeding speed of 0.10m/s respectively. And packaging speed of green peppers and carrots was improved by 3.7 and 3.4 times compared with manual packaging. The packaging condition with the prototype was good and the products had almost no damages.

The exports of plywood are increasing annually and it has ranked first in the world market because of the high quality product and manufactured using mordern techniques. However, it is known that the exports of the other wood products, except plywood, is inactive because of their low quality. Accordingly, to increase the exports of various wood products investigations were carried out on kiln drying techniques to improve the quality of the wood. Wet wood should be kiln dried before use to prevent various drying defects such as distortion, shrinkage etc., which would develop after processing,:and also wet wood is not suitable for cutting, gluing and finishing. Therefore, the kiln drying properties of lumber from such species as oak, ramin and meranti which are used in large quantity for manufacturing exporting wood products have been studied. The results of the research are summarized as follows. (1) The end checks and the time for drying from initial moisture content of about 40 percent to 5 percent moisture content in ovendry were investigated as follows: (2) The kiln dried results, for 30mm stock, which are presented by using kiln schedule table 3 are as follows: (3) The kiln schedules for ramin, meranti and oak are given respectively as follows: Ramin kiln schedule: Table 17 and Table 18. Meranti schedule : Table 12. Oak schedule : Table 15.

Six total mixed rations (TMR) containing 0, 4, 6, 8, 10, 12% tannin (TMR I-VI), using Accacia nilotica pods as a source of tannin, were used to study the effect of Acacia tannin on in vitro nutrient digestibility and gas production in goats. This study also investigated the degraded products of Acacia nilotica tannin in goat rumen liquor. Degraded products of tannins were identified using high performance liquid chromatography (HPLC) at different hours of incubation. In vitro digestibility of dry matter (IVDMD) and organic matter (IVOMD) were similar in TMR II, and I, but declined (p<0.05) thereafter to a stable pattern until the concentration of tannin was raised to 10%. In vitro crude protein digestibility (IVCPD) decreased (p<0.05) with increased levels of tannins in the total mixed rations. Crude protein digestibility was much more affected than digestibility of dry matter and organic matter. In vitro gas production (IVGP) was also reduced (p<0.05) with increased levels of tannins in the TMR during the first 24 h of incubation and tended to increase (p>0.05) during 24-48 h of incubation. Gallic acid, phloroglucinol, resorcinol and catechin were identified at different hours of incubation. Phloroglucinol and catechin were the major end products of tannin degradation while gallate and resorcinol were produced in traces. It is inferred that in vitro nutrient digestibility was reduced by metabolites of Acacia nilotica tannins and ruminal microbes of goat were capable of withstanding up to 4% tannin of Acacia nilotica pods in the TMR without affecting in vitro nutrient digestibility.
