In order to develop local innovation in Taiwan's traditional industries and products with local characteristics, and with market mechanisms in which society demands diversified consumer choices, there is now a trend among local industries to gradually broaden their product features and thus increase market demand. However, most traditional products with local characteristics are different from the well-known domestic products in terms of innovative identity and optimization of quality. The purpose of this study is to apply a Miryoku (attractiveness) Engineering evaluation construct and a Kano two-dimensional quality model to investigate the quality of bamboo charcoal-derived products with traditional local characteristics as well as their product planning and improvement strategies. This study used a theoretical approach, in-depth interviews, and statistical analysis of questionnaires. The study aims to gain a deeper understanding of current consumer perceptions of traditional local industries and products, the quality elements of product planning and design, and indicators that denote areas for improvement, so that practical suggestions can be made.

Cu and Zn are frequently added to livestock diets as additives to increase feed efficiency and production. This practice resulted in the higher contents of Cu and Zn in excrement of livestock. The aim of this study is to evaluate the effect of Cu and Zn concentration of manure compost and its application rates on the production and quality of pakchoi and rice. The pot experiments were conducted and the six manure compost were applied at 3 rates (20, 40, and 80 ton/ha), including the control and chemical fertilizer treatments. Results showed that the yield of the crops was enhanced by the compost application, and the Cu and Zn concentration in the edible part of crops were in normal range (pakchoi: Cu 1.8-10.4 mg/kg, Zn 39-160 mg/kg; rice grain: Cu 0.6-4.0 mg/kg, Zn 58-79 mg/kg). The potential risk of long-term manure compost application on soil quality was also evaluated. The total Zn concentration in soils may reach the regulation standard after 22 years of manure compost application at the rate of 40 ton/ha/year.
