Purpose - Considering the environmental issues in corporate management is now a necessity, not an option. In addition, consumers' interest in health and environment has increased rapidly. This study aims to investigate how the management style that pursues environmental protection affects the various outcomes at each management process such as planning, producing and supervising process. Research design, data, and methodology - We surveyed 319 manufacturing companies from April 1 to April 30, 2016. Green purchasing, environmental technology management and management support are selected as independent variables and firm performances as dependent variables. Three analyses including factor, regression and moderating were conducted. Results - Regression analysis was performed to set up hypotheses. Consequently, the total six hypotheses were adopted and then innovative management style showed moderating effect. Conclusions - Companies should consider environmental factors to improve the financial performance in the long term. Especially the cooperative style enhances financial performance by implementing eco-friendly design in cooperation with customers. Also, eco-friendly activities with suppliers could have direct environmental protection effects. Therefore, a manufacturer needs to cooperate with both suppliers and customers to maximize the protection effect. The production of eco-friendly products and implementing eco-friendly design with customers positively affect product quality.

Objective : The present study was intended to develop a design ideation and evaluation process for the development of ecology-, ergonomics-, and economy-friendly ($E^3$-friendly) products. Background : Due to increasing social and legal requirements on global sustainability, manufacturing companies have made more efforts ever than before for the development of eco-friendly products. However, most eco-friendly products are often criticized due to lacking ergonomic and/or economic considerations. Method : An $E^3$-friendly product development process consisting of (1) survey of eco-friendly products, (2) characterization of eco-friendly products, (3) design ideation for $E^3$-friendly product, and (4) design idea evaluation for $E^3$-friendliness was established and applied to the development of a novel product which supports drinking of daily recommended amount of water. Results : Fifty-five design characteristics were identified by a survey of forty eco-friendly products and incorporated into the proposed ideation and evaluation process. New ideas and design changes were developed effectively using the proposed development process for a novel $E^3$-friendly bottle for support of water drinking. Conclusion : The proposed process was found effective for the development of eco-friendly design ideas and improvements. Application : The proposed system would be of use to develop better design ideas having market competitiveness.

An underground electric switch is a high-voltage switch used in distribution network systems for a reliable power supply. Many studies are being conducted to expand the switch to use an eco-friendly gas using dry air instead of SF6 gas to reduce greenhouse gas emissions. In this study, a flow analysis model was established to improve the performance of an eco-friendly gas switch. The results were compared and reviewed through experiments. For the optimal arc grid design applied to the switch, the flow characteristics based on the flow path configuration and the changes in arcing time for each configuration were compared. Flow analysis can predict the switch flow distribution, and a comparative review of the flow path configurations of various methods is possible.

The purpose of this study is to develop a method of evaluating eco-efficiency of concrete based on environmental load emission, manufacturing cost, and durability in the concrete production process. Eco-efficiency is an advanced concept used to evaluate eco-friendliness of concrete. This technique intends to produce environment-friendly and highly durable concrete while minimizing environmental load on the ecosystem and manufacturing cost based on the results of service life assessment on concrete. This technique can be utilized to efficiently evaluate sustainability of concrete and find methods to improve it. Furthermore, the vision of this study is to contribute to implementation of environment-friendly concrete and construction industry.

This study has an innovative improvement of the ocher tiles production system that aims to resolve social issue of industrial waste and to meet the customer needs for environmental-friendly building materials. By changing a wet type cutting method to a dry type of ocher tiles production system, the three processes such as cleaning, dehydration, and drying can be removed in existing overall process of 17 steps. Accordingly, the application of the wet type cutting method, which is proposed in this study, makes an increase in ocher tiles production from 1,500 to 1,850 pieces per hour. In particular, industrial wastewater that was emerging as the biggest problem in environmental pollutants in the wet cutting method has been removed. In addition, the most serious problems of noise and dust from the operator side, while developing a device for the dry cutting method, are eliminated through the development of additional equipment.

Recent years, many industries acknowledge that environmental substantiality of products must be an essential role and it is one of the major importances for industries to consider the environmental impacts of products at the early stages of product development. This study investigated eco-design parameters and $CO_2-eq$. emissions in each stage of raw material acquisition, manufacturing, transportation, use and disuse in life cycle of touch monitor stand based on Eco-Design. In this study, to fulfill of Eco-Design, the environmental impact assessment of through LCA(Life cycle assessment) was carried out with benchmarking monitor stand and we suggested the direction of new design of touch monitor stand mechanism based on eco-friendly considerations. New design based on LCT(Life Cycle Thinking) showed that the following eco-friendly considerations at the early stage of design to be helpful to reduce GWP(Global Warming Potential) [kg $CO_2-eq$.] in new monitor stand development and it is necessary for Eco-Design process of the product.

The applicability of rice husk fiber as a raw material for eco-friendly pulp mold was evaluated in this study. The higher demand of environmental friendly packaging material resulted in the more interest for the natural fiber based pulp mold. The rice husk which is an abundant agricultural byproduct in Asia could be defiberized by an alkaline digestion process. The changes in the pulp mold making process and the properties of pulp mold by the addition of the rice husk were investigated. The addition of rice husk fiber to the pulp mold made with OCC or UBKP resulted in the increase in drainage at the pulp mold forming process. In case of UBKP pulp mold, the addition of rice husk fiber increased the drying efficiency after pulp mold forming since the structure of pulp mold became more bulkier by the addition of the rice husk fiber. Those results showed the rice husk fiber could be applied to the pulp mold manufacturing as one of the eco-friendly natural fiber resources.

The world has faced with various environmental problems such as climatic change, global pollution, and depletion of natural resources. Conventional economic development continues not only to intensify the magnitude of the problems but also to damage growth potential of future generations. Therefore, recent manufacturers are highly required to accommodate themselves to sustainable development that aims at preventing the loss to the future generations. Moreover, the manufacturers are under heavy pressure from various environmental regulations. This paper proposes green bill of material (Green-BOM) which conforms to the environmental regulations to restructure eco-friendly manufacturing system. Green-BOM is useful for managing green product and process information to satisfy several environmental regulations by recording energy consumption, recycle rate, volatile organic compounds (VOCs), substance information, and so on.
