Remanufacturing is an industrial manufacturing process. The merits of remanufacturing are to reuse old products to perform like a new product and to save energy, natural resources, landfill space and to reduce air pollution by less re-smelting. This paper proposes a systemic approach for activating the domestic remanufacturing industry. The approach is based on inside and outside regulations to apply remanufacturing companies. And, we analyzed the state and problems of remanufacturing industry for automobile parts.

본 연구에서는 우리나라의 제조업을 대상으로 에너지소비, 생산, 수출의 상호 인과관계를 분석하였다. 우리나라 제조업을 9개 산업으로 나누어 1991년부터 2013년까지 패널 데이터를 구축하여 VECM 방법론과 더불어 Demitrescu and Hurlin (2012)에 의해서 개발된 패널 Granger causality test 방법을 사용하였다. 분석결과에 의하면, 생산에서 에너지소비로, 수출에서 에너지소비로의 Granger Causality가 존재하였다. 하지만 그 역으로는 Granger Causality가 성립하지 않았다. 따라서 제조업부문의 에너지절약정책은 생산이나 수출에 역효과를 발생하지 않으면서 추진될 수 있다는 Qzturk (2010)의 보존가설을 지지하고 있다. 장기적으로는 생산, 에너지소비, 수출, 노동, 자본 간에 장기 공적분관계가 존재하며, 장기균형관계에서 에너지소비가 생산의 증가에 기여하는 것으로 나타났다.

대구 무형문화재인 하향주 생산의 표준화를 위하여 전통 누룩으로부터 29균주의 효모를 분리하다. 이들을 대상으로 산 생성능을 측정한 결과, 분리된 효모들은 산 생성능이 비교적 양호 하였고 분리된 효모들을 50% glucose가 첨가된 YM broth에서도 생육이 우수하였다. 10% 에탄올 농도에서도 내성을 나타내는 HA2 HA3, HA4 균주를 대상으로 주정계를 이용하여 에탄올 생성능을 측정한 결과, 각각 10.8%, 10.45%, 10%로 단 시간에 고농도의 에탄올을 생산하였다. 분리된 효모 중 내당성, 산생성능, 에탄올 생성능, 에탄올 내성이 우수한 효모 HA3을 하향주 주조를 위한 산업적 이용 균주로 최종 선발하였고 ITS 영역 증폭을 통하여 동정한 결과, HA3은 Saccharomyces cerevisiae와 97% 상동성을 나타내어 Saccharomyces cerevisiae HA3로 명명하였다. 선발된 효모인 Saccharomyces cerevisiae HA3를 주모로 첨가하여 하향주를 제조하여 전통적 방법으로 제조되는 하향주 발효와 비교한 결과, 환원당의 함량, 아미노산함량 pH 변화는 큰 차이가 없었으나 주모 첨가는 밑술 발효시 효모의 생육이 빠르게 유도되어 상대적으로 젖산균의 증식이 억제시킴으로써 유기산 중 lactic acid의 함량 및 높은 산도를 낮출 수 있었으며, 22%로 높은 알콜 발효력을 보였다. 또한 주모를 첨가하여 제조한 하향주는 관능적 기호도 평가에서 전반적 기호도가 전통적 제조법으로 주조한 하향주 보다 우수함을 확인하였다.

This research is about global investment for managing the important position, what Korea is doing in World's main market. Considering there are some differences between developed countries' model and developing countries' model in doing direct overseas investment, they target to get political agreement and develop the new invest plan and strategy by understanding changes of Korean manufacturing companies in direct overseas investment between 2001 and 2008 and analyzing the change of yearly investment motivation. The result from this result let us know that company should develop their own idea for their competitive advantage by doing direct overseas investment. And, the overseas investment, which was already done in other countries, 1. Review its realities and tendency in terms of investing countries, industries, and its scale and then Set up an actual model, based on strategic combination of investing location select and determination of Korean manufacturing companies. 2. Analyze how the situational factors have influenced and what factors would be considered for direct overseas investment. From the analyzing result, even though it is fairly true that raising wage and getting resources, and developing alternating industries for export had influenced at the beginning, overseas investing companies' policy will be influenced by the results from studying marketing-pursuit type, local producing and manufacturing by using low-wage people for local sale, and situation for changing investing tendency as service industry.

The purpose of this study lies in enhancing an understanding of on-line collaboration among manufacturing companies for innovation. To meet this purpose, this study adopts Eisenhart(1989)'s case study approach to explore the success factors of on-line collaboration among Korean small-medium-sized manufacturing companies. Firstly, an exhaustive case study is conducted for four collaboration hubs in the Korean injection mold industry. This study identify the success factors through a structured questionnaire survey and in-depth interviews based on experts of K Institute, which performs the overall management of the collaboration hubs, and personnel of the participating businesses and vendors. Secondly, AHP analysis is conducted to identify the priorities among the success factors. Finally, several propositions of on-lin collaboration are derived.

Total quality management (TQM) is regarded as a tool for improving the competitiveness not only for a manufacturing sector, but also for a service sector, The objective of this paper is to classify TQM education by management level, to identify how TQM education be implemented by the type of industry, to analyze the relationship of TQM education with business performance, and finally to analyze the difference between companies with ISO certification and those without ISO certification in terms of TQM education. The findings suggest that there was a significant difference between manufacturing and service sector in TQM education level. Also, the relationship of TQM education with business performance was partially correlated. Finally there was no significant difference between companies with ISO certification and those without ISO certification in terms of TQM education.

In Build-to-Order manufacturing systems, products are usually manufactured by a pull system. The manufacturers order only what they need when it is needed. The suppliers are expected to deliver parts as much as needed. When the part demand fluctuates significantly, this places lots of challenges on the suppliers. In this letter, we explore the decision issues regarding part supplies for Build-to-Order manufacturing systems, especially in the auto industry, and suggest how to address them in order to make the manufacturing systems work more efficiently.

Forging is a manufacturing process involving the shaping of metal using localized compressive forces and the process of deforming metal into a predetermined shape using certain tools and press according to the temperature. Forging provides stronger metal parts than that possible by casting or machining. Conventional clutch jaw parts have been developed through cold forging and precision machining; however, fabrication of integral clutch jaw parts for farm machinery has not been reported yet. These parts were developed by applying a complex forging technology combining cold and hot forging. The integrated forming technology proposed in this study will be useful for reducing the lead-time for manufacturing, improving the accuracy of products, and eliminating the welding process.
