A mim turbo-shaft engine of 50HP for UAV, which can be easily modified to turbo-prop and turbo-jet engine by sharing the core engine and has many applications to civilian demands and munitions, will be developed This kind of micro gas turbine engine has been developed mostly by the corporations which have special technology but are small in its scale. Especially, the gas turbine engine can be easily applied to other fields and developed by domestic technology, so that the sharing of technology is planed to realize through the cooperations with academies and research institutes. In this paper, the gas turbine engine, which has the compressor ratio of 3.8, the turbine inlet temperature of l180K and the engine speed higher than 100,000 rpm, is composed of centrifugal compressor, combustor, gas generator turbine, free power turbine and gear box. The competitiveness of the gas turbine engine can be obtained from minimizing its cost by the utilization of domestic infrastructure for the performance test and the decisive outsourcing.

As various manufacturing technology of optical glass is developed, the aspheric lenses are supplied to many fields. Electronic or measuring instruments equipped with aspheric lens have recently been used since aspheric lens is more effective than spheric one. However, it is still difficult manufacture glass lens because of high cost and the short life of core. The demands of the aspheric glass lenses increase since it is difficult to obtain the desirable performance in the plastic lens. For the mass production of aspheric lens, specific molds with precisely machined cores should be prepared. In order to obtain competitiveness in the field of industrial manufacturing, a reduction in the development period for the batch machining of products is required. It is essential to analyze the stress distribution and deformations of machining system which is used for manufacturing the aspheric lens using FEM software ANSYS. Finite element simulations have been performed in order to study the influence of machining system which is developed in this study on structures. It is very important to understand the structural behavior of machining system. This paper investigated the static analysis and dynamic analysis of machining system for aspheric lens to predict the damage due to loading.

ERP is an essential information system (IS) that many companies are operating on the basis of this solution. Since ERP is a very important system that is used in business operation and provides quantified information about the efficiency and productivity of the business activities, difference of competitiveness between companies that have successfully implemented ERP and those that do not have is very large. According to a survey done by a global consulting firm, far less than half of the companies are evaluated as successfully internalizing ERP into their organizations. Therefore, there is a need for an accurate assessment of ERP usage and an improvement of ERP based on it and the need become to increase largely. However, in reality, there is neither the systematic evaluation methods or any research about this topic. This study proposes a framework for evaluating the routinization of ERP throughout the life cycle of the ERP based on both the literature in the enterprise architecture, ERP lifecycle, ERP success areas, and actual experience of the authors in ERP implementation. The proposed framework intends to satisfy the following functional requirements : 1) the entire lifecycle of ERP should be evaluated; 2) evaluation of ERP should be performed from the enterprise-wide perspective; 3) evaluation should focus on the core activities of the organization; and objective evaluation criteria should be used in the evaluation.

중소기업의 글로벌화는 최근 화두가 되고 있는 창조경제의 핵심성과이다. 글로벌화를 위해서는 다양한 노력이 필요한 가운데, 본 연구에서는 중역들이 글로벌화를 추진하기 위해서 어떠한 동기부여가 필요한가에 대해서 확인하는 것에 초점을 두고 있다. 실증분석 결과, 중역들의 심리적 소유의식은 중소기업의 글로벌화에 강한 유의미한 영향을 미치는 것으로 나타났고, 중역들의 소유의식은 의사결정 참여, 정보습득 권한, 그리고 절차적 공정성의 강화를 통해서 고취될 수 있다는 것을 실증적으로 제시하고 있다.

This paper is an attempt to understand the external technology acquisition (ETA) process of the machinery SME sector in Bangalore city, India. With the onset of economic liberalization, Bangalore based machinery SMEs have significantly shifted their ETAs from India to abroad, particularly Germany and Japan, among others. The primary objective of ETAs is to enhance their competitiveness by means of improving product quality and productivity as well as meeting customer demand. Replacing outdated machinery or overcoming technological obsolescence is a primary objective of only a few. As a result, majority of the SMEs has gone for multiple ETAs since their inception and we found a statistically significant positive correlation between firm age and number of ETAs. The present study has made two empirical contributions: (i) We have thrown light on the core technology up-gradation issue - How do SMEs approach the problem of external technology acquisition in the current globalization era? (ii) We are able to identify and develop a map of ETA process based on the "learning and experiences" of these SMEs.

The development and maintenance of human capacity in economies is critical to long term competitiveness, but also for the overall health and environment of regions. Yet, human science and technology-based capacity is multidimensional and has interrelated characteristics which present certain policy challenges. This paper addresses a range of issues specific to a discussion on human capacity in S&T. First, the paper emphasizes the importance of acknowledging the complexity of human capacity issues and how they evolve along the STEM (science, technology, engineering, and mathematics) pipeline. The pipeline is an often used reference to describe the training and development in STEM disciplines, from early childhood education, to more advanced training, and finally to professional collaboration and interaction and serves as a useful organizing framework for the discussion of capacity along the career evolution process. Second, the paper offers an organizing framework for discussion of policy mechanisms that have been developed to address issues and gaps that occur along this STEM pipeline. Specifically, it contrasts the traditional mechanisms of building human capacity in STEM areas with newer "gap filling" and integrated approached to addressed human capacity disparities and priorities. Third, the paper addresses core challenges in human capacity in STEM, including the education and training, participation of women and underrepresented groups, brain drain/brain circulation issues, and the globalization of science. The paper concludes with a discussion of policy implication for the development of human capacity.

국내 섬유산업은 디자인, 브랜드, 인지도 등에서는 선진국에 비해 떨어지고 있고, 중 저가 제품에서는 개발도상국에 비해 경쟁력이 떨어지는 상황이다. 또한 섬유산업 시장은 공급자 중심의 시장에서 소비자 중심의 시장으로 변하고 있다. 최근 이러한 환경변화에 대응하기 위한 핵심기술로 RFID가 주목받고 있다. RFID는 라디오 전파를 활용하여 인지된 사물 간 정보를 교환하는데 이용되는 기술로써 사물을 인식, 추적 그리고 식별을 가능하게 한다. 본 연구에서는 국내 섬유산업의 특징 및 현황과 RFID의 최신 기술동향을 검토하였다. 또한 국내 및 국외 섬유산업의 RFID 적용 사례를 분석하여 섬유산업의 RFID기술 적용 방안을 제시하였다.

The purpose of this study is to detect the factors which have an effect on transformation level and performance and to provide the ways of successful transformation and vitalization from OEM to ODM. This study was proceeded by an empirical analysis. A model and hypotheses were set up and they were verified through the empirical analysis. Those factors were divided into four, inner company factors, strategic factors, core competence factors and purchase determining factors. In the result of the model suitability analysis on the study model of relationship among 'influencing factors of ODM transformation - ODM transformation level-export performance', every factors, $X^2=912.067$, DF=261, p value=0.000, GFI=0.737, AGFI=0.620, NFI=0.786, IFI=0.837, CFI=0.834, Q value=3.495 were rather insufficient to be a good model, but they were good enough for the general analysis. Taking these accounts into consideration, this study suggests the following implications. First, making a plan and setting up strategies in advance are required. Second, financial plan has to be prepared. Third, trends in global markets have to be analyzed. Fourth, companies have to focus on developing new materials and products through R&D. Fifth, quality competitiveness and quality control systems are required.
