Along with the increasing social concern on cultural products and corresponding policy development by government many domestic regions have been trying to establish their own cultural identity. Based on the case stuffy for Gwang-Ju, this paper provides a methodology of developing cultural products from the unique regional resource. Its scope was classified into three categories: alread-developed, regional character and regional theme products. For this purpose, marketing strategies were established for quality improvement and promotion of cultural products through analysis on the current products including a questionnaire to customers. Then, conceptual designs for each scope were developed through the five steps of "selection of items", "target customer analysis", "concept establishment", "extraction of cultural factos7" and "derivation of conceptual design". The concept establishment was based on the expression of the material characteristics, the harmony of tradition and modernity, symbolization of images and so on. The cultural factors taken into account included the natural resources, historical heritages and landmarks. Finally, several examines of the conceptual designs were illustrated for commercial products. This study could be extended further in the future by introducing potential immaterial resources into the cultural factors.

Generally, Hertz theory is used to analyze the contact problem of two bodies. It is simple derivation of solution in the contact part. And calculation time is short Moreover, it can mean well that many wear occurs relatively. However, material property becomes plastic deformation when large perpendicular pressure acts on a small contact surface product. In this case, Hertz theory is inapplicable. Therefore this thesis carried the finite element analysis in consideration of material elasticitystrain and the shape of the geometric from contact point. And it compared with Hertz theory that change of the contact surface and contact pressure.

By the treatment of various mutagens, a number of 5'-guanylic acidproducing from 5'-xanthylic acid were obtained from Brevibacterium ammoniagenes ATCC 6871. The indispensable genetic characters of the mutants were adenine requirement, lack of GMP-reductase and mutation to adenosine resistance from adenosine sensitiveness. Main product of these mutants from 5'-xanthylic acid was 5'-guanylic acid. The substance was isolated in a crystalline form the culture broth of BA 17-2, and identified as 5'-guanylic acid by means of paper chromatography, ultra violet, absorption spectra, and infra red spectrum.

A good understanding of the chemical composition and structural characteristics of a carbonaceous material is essential in conversion processes. Understanding how the composition and structural changes influence the burning behaviour of coal is important when assessing a coal's potential for utilization. To explore the potentials of a typical Nigerian coal, both conventional and advanced analytical techniques such as proximate analysis, ultimate analysis, calorific value, surface area analyser, SEM, FTIR, XRD and SAXS were employed. The results obtained from these characterizations agree favourable well with a typical South African coal that is of enormous contribution to the gross domestic product (GDP) of the nation economy.

현재 기술발전에 따라 급변하는 제품의 패러다임은 다양화 되어가는 사용자의 감성적 니즈의 변화와 밀접한 관련이 있다. 이것은 사용자들이 제품의 규격화 된 형태와 편리성을 강조하기보다는 감성적 가치 부여를 지향하고 있기 때문이다. 이러한 감성적 가치는 사용자의 제품에 대한 니즈로 연결되고, 궁극적으로는 제품의 구체적인 속성에 의해 충족될 수 있다. 창의성은 디자인 분야뿐만 아니라 미래사회에서 가장 중요한 경쟁력을 갖게 하는 요소로 대두되고 있다. 그리고 디자이너는 주어진 것에 순응하는 사람이 아니라 끊임없이 새로운 지식과 가치를 창조해 나가는 지식 노동자이며, 경쟁력에서 이길 수 있는 가장 부가가치 있는 부분이 창의성이라 할 수 있다. 결국 창의적 디자인은 사용자에게 심리적 감흥을 불러일으켜 기존 제품들과는 차별화된 새로운 디자인 해결안으로서 그 가치를 인정받는 것이다. 본 연구는 창의적 디자인에 있어 사용자의 의식 또는 무의식의 니즈에 대하여 디자인 구성요소와 심미성 요소를 파악하여 차별화된 창의적 디자인의 제품 개발에 있어 구체적인 디자인 요소를 설정하고 심미성 요소를 통한 디자인 컨셉 도출 과정에 활용될 수 있는 가이드라인을 제시하고자 한다.

Recently, in construction equipment machinery production, development has focused on environmentally-friendly functions to improve existing production capacity. For excavators as well, emphasis has been placed on response to environmental regulations, miniaturization, and noise reduction, while technology is being developed considering cost reduction and safety.Accordingly, the front support, an inner reinforcement part of the excavator, as well as high-strength steel plates to improve safety and reduce weight, are being applied.However, in the case of high-strength materials, Springback occurs in the final formed part due to high residual stress during product forming. Derivation of a forming or product shaping process to reduce springback is needed. Accordingly, regarding the front support, an inner reinforcement part of the excavator, this study derived a method to improve springback and secure shape stiffness through analysis of the springback occurrence rate and springback causes through a forming analysis.As for the results of analyzing the springback occurrence rate of existing products through forming analysis, springback of -22.6 mm < z < 27.35 mm occurred on the z-axis, and it was confirmed that springback occurred due to the stiffness reinforcing bead of the upper and middle parts of the product.To control product residual stress and springback, we confirmed a tendency of springback reduction through local pre-cutting and stiffness reinforcement bead relocation.In the local pre-cutting model, springback was slightly reduced by 5.3% compared with the existing model, an insignificant reduction effect. In the stiffness reinforcement bead relocation model, when an X-shaped stiffness reinforcement bead was added to each corner portion of the product, springback was reduced by at least 80%.The X-shaped bead addition model was selected as the springback reduction model, and the level of stiffness compared to the existing model was confirmed through a structural analysis.The X-shaped bead additional model showed a stress springback of 90% and springback reduction of 7.4% compared with the existing model, indicating that springback and stiffness will be reinforced.
