This study aims at evaluating the environmental impacts stemmed from the End-of-Life Vehicle(ELV) treatment systems in Korea, using Life Cycle Assessment(LCA) method. In this study, both environmental burden from the ELV dismantling process & recycling processes and environmental benefit which were derived from the avoided environmental impacts by substituting recycled materials for virgin materials were considered. First of all, the key issues which were defined as the environmental aspects that account for more than $1\%$ out of the total environmental impacts were identified from the Life Cycle Impact Assessment(LCIA). $CO_2$, crude oil, natural gas, coal, etc. were found out to be the key issue parameters. From the LCI Analysis and LCIA studies, it was shown that the significant environmental aspects were related with the recycling process of ferro scrap, the shredding process of compressed car bodies and the dismantling process of end-of-life engines. In particular, the recycling process of ferro scrap has the most significant effects on the environmental impacts of the ELV treatment systems. Based on these results, it is recommended to improve the recycling process of ferro scrap in order to make the ELV treatment systems more environmentally sound.

Purpose: The work aimed to integrate and distribute the knowledge of marketing and chemistry for product development, in which individual packaging from water hyacinth was ideal. Research design, data, and methodology: A customer perception was surveyed to guide the preparation process, and eco-packaging preparation followed the perception study. The satisfaction with the packaging using the 4Ps was determined. Results: 159 samples participated in the survey to establish their perceptions. They perceived that eco-packaging was a friendly environment with a score of 4.47. The uses of chemicals and water were less. The design for other functions than a normal function of packaging was preferred. The pulping was done using 3.0 M NaOH. The natural additives of carboxymethyl cellulose (defibering) and corn starch (adhesive) were desired. The paper was characterized according to The National Standard of Kraft paper and was equivalent to the liner board. The prototype of packaging was fabricated as individual packaging. The marketing mix was used to survey 200 samples. The satisfaction with the product was the maximum at 4.53, while the minimum was on price. The online channel was preferred to access the product. Conclusions: Water hyacinth could be added value as eco-packaging that the qualities of pulp were equal to the Kraft paper. Individual packaging from water hyacinth was satisfied.

Purpose: This study is designed to grasp how consumers' beliefs about the lunch box attributes such as healthiness, diversity, price, hygiene, and package eco-friendliness affect consumers' perceived value and purchasing behavior. Research design, data, and methodology: The data were collected from 615 respondents composed of men and women aged 20 to 59 who purchased lunch box products and were sampled using the quota sampling method. An online survey was conducted. The data were analyzed using the measurement model and structural equation model assessment with SPSS 24 and SmartPLS 4.0. Results: First, healthiness, diversity, hygiene, and the price had a significant positive effect on the perceived functional value of consumers, but package eco-friendliness did not significantly affect functional value. On the other hand, healthiness, diversity, price, and package eco-friendliness were found to have a positive impact on consumers' perceived emotional value, but hygiene was found to have no significant effect on emotional value. It was found that functional and emotional values significantly positively affected repurchase intention. Conclusions: This study confirmed that consumers' belief in the product attributes of franchise lunch boxes influenced consumers' perceived value, which thus formed the attitude of consumers and showed a relationship that affects repurchase intention. At the end of this paper, the managerial implications for the franchise lunch box brand, the limitations of this study, and future research directions were presented.

The exchangeability of subassembly has a good relationship with the modularization of product. This relationship can be found by the analysis of the characteristics of a product. The weight for decision factors for the modularization can be determined by the exchangeability of a product or subassembly. The functions, structure, materials of subassembly are used as the decision parameters of exchangeability. Using these selected parameters, the modularization of a product, the characteristics of product structure, and the product function are analyzed. And then, the weighting factors could be calculated quantitatively using this relationship and the parameters of the exchangeability. The calculated weight can contribute to help a designer design for recycling (DFR), design for energy (DFE) and Eco-design.

Pump cap is a product that is widely used due to its ease of use and simple operation. These pump caps are applied to heterogeneous functional cosmetics and are being developed as dual pump caps. However, the conventional dual pump cap has a problem in that it is inconvenient to use and leakage occurs. In addition, it is formed of a plurality of materials, and there is a problem that is difficult to recycle. Lately, since the problem of environmental pollution is getting serious, the dual pump cap, which is difficult to recycle, cannot be used. Currently, eco-friendliness has been considered in Korea, and there are no dual pump cap containers with excellent sealing performance. Therefore, in this study, a dual pump cap container made of eco-friendly material was designed. In addition, finite element analysis was performed to verify the design feasibility of the product.

무기계 수지를 합성하여 압축강도 및 색도 변화에 대하여 조사하여 문화재 복원재료로서의 활용 가능성을 조사하였다. 무기계 수지로서 카올린을 $750^{\circ}C$에서 6시간 동안 하소한 메타카올린을 사용하였는데, 하소 후 카올린은 비정질 상으로 변화하였다. 메타카올린에 NaOH 수용액 및 물유리를 중축합 개시제로 사용하여 무기계 수지를 합성하고, 압축강도 및 색도 등의 특성을 측정하였다. NaOH 수용액의 농도 및 물유리의 농도가 높을수록 압축강도가 증가하였다. 알루미나의 첨가는 적은 양의 치환에는 압축강도가 감소하였으나 첨가량이 더욱 증가하면 강도는 증가하였다. 8일에서 100일 간의 태양광에 의한 노출실험 결과 대부분의 조성에서 색도는 식별 불가능한 범위 내에서 변화하였다. 그러나 유기 안료의 첨가는 메타카올린의 색도 변화를 증가시켰다. 이와 같은 무기계 수지의 색도 변화는 에폭시 수지에 비하여 매우 우수한 것으로 나타났다.

This paper presents a study on product design optimization to reduce the environmental impact of machining. The objective is to analyze the effect of changing the product design parameters such as its dimensions, and basic features on the environmental impact of machining process in terms of its energy consumption, waste produced and the chemicals and other consumables used up during the process. To realize this objective, we used a CAD model of a product with different design scenarios, and analyze their energy consumption using an environmental impact calculator method developed. The waste produced, and the consumables used up, such as lubricants and coolants were analyzed using environmental emission factors. Optimization methods using Genetic Algorithm and Goal Programming are applied to the product design parameters in order to get the best possible product dimensions with the least environmental impact of the machining process.

In Korean Electric Motor Unit(EMU) industry, the government should lead and drive the development of the product-oriented fundamental technologies(for example, Life Cycle Assessment, Environmental Labelling, Ecodesign, Eco-efficiency etc.) for the EMU. International Railway Union(UIC) establish UIC code 345: Environmental specification and it is based on using the product-oriented fundamental technologies. And also many foreign railway related companies already shown their environmental performance using the product-oriented fundamental technologies So, in Korean situation, it is important that let the EMU industrial player understand the importance of the product-oriented fundamental technology for the EMU and clarify who drive the development of the product-oriented fundamental technology for the EMU and what the type of driving forces.
