This study examines the effects of entrepreneurial orientation and external oriented organizational culture on the firm perfornamance focusing on mediating effects of open innovation. The survey was conducted on Korean manufacturing firms with 100-5,000 employees among listed companies and external auditing companies. The validity of the research model and hypotheses was verified through analysis of structural equation model for 283 valid responses. Empirical results show that entrepreneurial orientation positively affects both open innovation and firm's performance. The external oriented organizational culture of firms appears to be positive effects on open innovation, but the effect between the external oriented organizational culture and firm's performance shows no statistical significance. Open innovation have positive effects on firm performance. In addition, a test for mediation effects of open innovation reveals that a full mediation exists between the external oriented organizational culture and firm's performance, while there is a partial mediation effect between entrepreneurial orientation and firm's performance. This study contribute to the literature by deepening understanding on the open innovation. We propose an integrated model for examining antecedent factors, open innovation and performance.

As the size of semiconductor chip shrinks, the electronic industry has been paying close attention to fan-out wafer level packaging (FO-WLP) as an emerging solution to accommodate high input and output density. FO-WLP also has several advantages, such as thin thickness and good thermal resistance, compared to conventional packaging technologies. However, one major challenge in current FO-WLP manufacturing process is to control wafer warpage, caused by the difference of coefficient of thermal expansion and Young's modulus among the materials. Wafer warpage induces misalignment of chips and interconnects, which eventually reduces product quality and reliability in high volume manufacturing. In order to control wafer warpage, it is necessary to understand the effect of material properties and design parameters, such as chip size, chip to mold ratio, and carrier thickness, during packaging processes. This paper focuses on the effects of thickness of chip and molding compound on 12" wafer warpage after PMC of EMC using finite element analysis. As a result, the largest warpage was observed at specific thickness ratio of chip and EMC.

섬유산업은 원가 경쟁력 향상과 산업 고도화에 필요한 미래형 저에너지 염색가공 핵심 기술을 통한 고부가가치 섬유제품의 창출과 섬유산업의 선진화달성에 꾸준히 노력을 해 왔다. 염색가공업의 에너지 소비는 섬유산업에서 염색가공업이 연료 사용량의 77%, 전기사용량의 54%를 차지하여 섬유산업의 에너지절감을 위해서는 염색가공 공정에서의 에너지 절감이 가장 중요하다. 국내 염색가공 분야의 4백여 업체를 대상으로 실시한 애로 기술에 관한 설문 조사결과에 따르면 염색공업의 에너지 절약형 구조로의 전환을 위해서 가장 시급히 요구되는 우선기술 1순위는 에너지절약형 염색가공 공정기술로 에너지 절감의 필요성을 반영하고 있다. 효소(Enzyme)가 섬유산업에 도입되기 시작한 것은 면섬유의 호발에 아밀라제가 사용되기 시작하면서 부터이며, 최근 유럽선진국들의 강화된 환경규제와 눈부신 바이오테크놀러지(Biotechnology)의 발전에 기인하여 섬유산업에서 관심과 적용이 확대되고 있다. 섬유산업에서 효소적용의 장점은 효소 그 자체가 자연산물이기 때문에 생분해 되고 중성에 가까운 pH에서 반응하므로 처리액이 환경문제를 일으키지 않으며, 기질특이성을 가져 매우 선택적으로 반응하여 부반응으로 인한 섬유의 손상을 최소화 하는 효과를 들 수 있으며, 무엇보다 소량 저온반응으로 인한 에너지절감이 가장 큰 장점이라 할 수 있다. 실제 섬유산업에서는 전분호제를 제거하는 아밀라아제, 데님워싱 및 면섬유의 후가공에 사용하는 셀룰라아제, 표백 후 잔류하는 과산화수소를 제거하는 카탈라제 등을 적용하는 사례가 많아지고 있으며, 이 밖의 다양한 공정에 효소 이용연구가 활발히 진행되고 있다. 본 연구에서는 그 동안 섬유 업체에서 직물의 표면 잔털을 제거하여 매끄러운 외관과 선명한 색상을 재현하기위해 후가공으로 셀룰라아제를 이용했던 공정을 개선하여, 효소를 이용한 정련-Bio polishing-염색의 3공정을 1욕처리를 통해 기존 단독으로 진행되어진 기존제품과의 중량, 외관, 색상재현성, 정련성 등을 비교하여 에너지 절약형 공정기술의 효과를 극대화 해보았다.

Membranes are used in most processes of biopharmaceutical production. It is used for pretreatment of other processes, separation of impurities in the process, virus removal, control of products concentration and buffer solution exchange. Virus filters play an important role in ensuring product efficacy and stability because viral contamination of biopharmaceuticals for humans is a sensitive issue that is directly related to serious clinical outcomes. Virus filters typically have complex multilayer structures made of various polymers such as surface-modified PVDF, PES, CRC. Depending on the manufacturer, filters have different pore structures and shapes, such as symmetric or asymmetric, and is used in the form of pleated membrane, flat sheets or hollow fibers. Virus filters are exclusively supplied by few foreign companies such as Asahi Kasei, Millipore, Pall and Sartorius. Replacing virus filters can be time consuming and expensive, including approval from regulatory agencies through validation. As localization has become important due to Japan's recent export regulations, it is necessary to increase the degree of technical independence.

Since China reformed and opened up itself, processing trade system has enormously contributed to chinese economic development and also become driving force of chinese economic growth. However, due to imbalance of industrial distribution, overproduction of labor-intensive product has expanded, and as a result, mass export of low-value-added products has aggravated trade friction. Also, these low-value-added products has caused environmental pollution and brought resource waste. On this, Chinese government start to modify system according to strategy for enhancement of processing trade. In this study, as a countermeasure of the Change of Chinese processing trade system, applicability of the bonded area is suggested. Firstly, even if a company's item is applied to prohibited or restricted items, the company can trade if through the bonded area. Secondly, even if a company has duty of deposit reservation, the company can be exempt from duty of deposit reservation if through the bonded area. Thirdly, as to importing facilities for processing trade, a company can receive more benefit through the bonded area than through outside of the bonded area.

Along with the increase of internet shopping, crimes that exploited personal information on the invoice of goods are becoming more and more advanced and becoming more and more classified from the interception of goods through voice phishing attack, injury, sexual offense. Therefore, in order to guarantee the anonymity of the customer's delivery information, there is a need for a delivery tracking prevention system which keeps the route information of the product's destination secret among delivery companies. For this purpose, We suggest that delivery tracing protect model based smart contract for guaranteed anonymity to protect the anonymity by encrypting delivery information and by separation of payment and personal information using the anonymity technique of block chain-based cryptography. Our proposed model contributes to expansion of internet shopping based on block chaining by providing information about product sales to company and guaranteeing anonymity of customer's delivery information to customer.

We examine the current status of smart factory deployment and diffusion programs in Korea, and seek to promote manufacturing innovation from the perspective of SMEs. The main conclusions of this paper are as follows. First, without additional market creation and supply chain improvement, smart factories are unlikely to raise profitability leading to overinvestment. Second, new business models need to connect "manufacturing process efficiency" with "R&D" and "marketing" in value chain in smart factories. Third, when introducing smart factories, we need to focus on the areas where process-embedded technology is directly linked to corporate competitiveness. Based on the modularity-maturity matrix (Pisano and Shih, 2012) and the examples of U.S. Manufacturing Innovation Institute (MII), we establish the new smart factory deployment policy measures as follows. First, we shift our smart factory strategy from quantitative expansion to qualitative upgrading. Second, we promote by each sector the formation of industrial commons that help SMEs to jointly develop R&D, exchange standardized data and practices, and facilitate supplier-led procurement system. Third, to implement new technology and business models, we encourage partnerships, collaborations, and M&As between conventional SMEs and start-ups and business ventures. Fourth, the whole deployment process of smart factories is indexed in detail to identify the problems and provide appropriate solutions.
