Goverment and enterprises have been devoting a lot of dffort in order to prevent the loss of human and property due to a large, diversified fire, explosion, global warming and disasters caused by natural phenomena. But Enterprises came forward and running in the economy priority policy for profit-seeking until now in order to meet the macro purpose of quality improvement of national life and welfare promotion in company with National growth, as a result of lax risk management have had to endure the loss of precious lives and property. According to the '2007 Survey of public safety for the activation of the safety culture' of National Emergency Management Agency [NEMA], a insensitivity of safety in our society was surveyed 'a serious level'. In this study, surveyed need of 'step-by-step fire protection safety management system builds' in order to prevent fire safety accident and improvement of safety awareness level through a systematic management and real condition estimation of not only large business that can control risk management, but also small business that has a big risk to occur accident easily according to small budget and organization.

The Small and Medium Business Administration specified 123 construction materials mandatory to purchase directly and forced the public owners to provide the contractors with materials as required by related law. This study extensively reviewed various characteristics and management factors of the owner-providing materials consumed in the public apartment housing under Direct Buying System(DBS) from the public owner's perspective. Subsequently, the major managed materials were identified, and the proper response plan was developed along the material procurement process. The Procurement Management Load Indices (PMLI) of 43 materials were evaluated according to rating criteria with procurement path, project-specified level, user requirement level, supplier's responsibility, on-site work requirement, additional parts, and inspection standards. The tile and aluminum windows were classified in the group needing high-level procurement efforts to reduce the errors and ensure the efficiency. The accurate quantity estimation method, definite purchase details, management activity definition before and after production, additional quantity for rework, interference coordination were defined as the essential activities for effectively responding to DBS.

This study develops a model fer establishing and operating "Arts and Humanities Business Incubators (AHBI)" to improve the productivity in the field of arts and humanities, the major resource of the knowledge-based society. The AHBI is a center that provides general assistance to those who want to start a new business in the area of arts and humanities and continue to provide managerial consultation to those who graduated from the AHBI. This research provides systematically how to provide the hardwares such as of office space and furniture, and how to supply the softwares such as management skills, financing, and marketing. This research indicates that the Ministry of Small and Medium-sized Industry should develop AHBIs, and suggests that the Ministry of Culture and Tourism establish AHBIs in its Cultural Industry Incubation Centers. This research expects that a government research institute or professional institute operates AHBI to create job opportunities for arts and humanities majors, to add the academic value of arts and humanities, and to vitalize the local economy.

Theoretically, this study reviewed effects that career orientation and entrepreneurial support programs as entrepreneurial support program of participation have on entrepreneurial intention. Based on this review, a research model was made. Then, this study empirically analyzed research hypotheses by classifying universities which establish entrepreneurship courses supported by Small and Medium Business Administration (as of 2006) and ones which do not into Seoul and regions, and business department and engineering department. Results of the empirical analysis were summarized as follows: First, career orientation was not significant in terms of entrepreneurial support program of participation. Second, autonomy orientation, technical competence orientation, managerial competence orientation, and entrepreneurial creativity orientation out of career orientation had significant positive effects on entrepreneurial intention, while security orientation resulted the same significantly positive effects but statistically insignificant. Third, entrepreneurial support program of participation had significant influence on entrepreneurial intention.

현재 투명전극은 주로 ITO를 사용하고 있으며, ITO는 인듐산화물(In2O3)과 주석산화물(SnO2)이 9대 1의 비율로 혼합된 화합물로 인듐이 주성분이다. 따라서 ITO 사용량의 증가는 인듐의 수요 증가를 이끌어 2003년 이후 인듐 잉곳의 가격이 급등하였다. LCD에 응용되는 금속재료의 가격추이를 비교해보면, 인듐이 가장 큰 변화를 보이고 있으며, 2005년 인듐 가격은 2002년 대비 1,000% 이상 상승하였다가 2007년 이후 500%p 하락하여 2008년 2월 22일 기준으로 톤당 49만 달러에 거래되고 있다. 같은 기간 동안 알루미늄의 가격은 76.6% 상승하였으며 구리는 394%, 주석은 331% 상승하였다. 이러한 인듐의 가격 상승폭은 동일한 기간 동안 다른 금속 재료와 비해 매우 크며, 단위 질량당 가격도 20배 이상 높은 수준이다. ITO의 주성분인 인듐의 이러한 가격의 급등 및 향후 인듐의 Shortage 예상으로 인해 ITO 대체재 확보의 필요성이 증가되고 있다. 태양광 발전산업에서 현재 주류인 결정질 실리콘 태양전지의 변환효율은 꾸준히 향상되고 있으나, 태양전지의 가격이 매년 서서히 하강되고 있는 실정에서 결정질 실리콘 가격의 상승 등으로 고부가 가치 산업유지에 어려움이 있으며, 생산 원가를 낮출 수 있는 태양전지 제조기술로는 2세대 태양전지로 불리는 박막형이 현재의 대안으로 자리매김하고 있으며, 박막태양전지 산업분야가 현재의 정부정책 지원 없이 자생력을 갖추고 또한 시장 경쟁력을 확보하기 위해서는 박막태양전지 개발과 더불어 저가의 재료개발도 시급한 상황이다. 본 연구에서는 In-line magnetron sputtering system을 사용하여 소다라임 유리기판 위에 박막태양전지용 투명전도성 ZnO(Al) 박막을 제작하였고, 특히 이 박막은 n-형 반도체 특성을 가져야하기 때문에 홀이동도와 개리어농도의 상관관계 및 박막의 두께, 광투과율 특성, 온도 의존성을 조사하였고, 이를 논하고자 한다.

The purpose of this study was to evaluate the effectiveness of the education program developed to raise the potential of entrepreneurial capabilities of senior citizens under the supervision of SMBA and investigate the effects of educational contents and environment on program satisfaction and entrepreneurial intention. The sample of this study was composed of 44 trainees who participated in the education program implemented by H University. Data were collected using self-administered questionnaires and analyzed employing paired-sample t-test and path analysis techniques. The study found that the program was effective in strengthening the potential of entrepreneurial capabilities of senior citizens and that educational content and environment had positive effects on program satisfaction, which in turn, positively impacted on entrepreneurial intention. The practical implications of the findings were discussed and the future directions for research were suggested.

This paper describes a nesting system of a computer-aided design of blanking and piercing for irregularly shaped sheet metal products. An approach to the system is based on knowledge-based rules. A nesting system is designed by considering several factors, such as utilization ratio which minimises the scrab for single or pairwise operation, bridge width, grain orientation and design requirements which maximise the strength of the part when subsequent bending is involve. Therefore this system which was implemented blank layout and strip layout module can carry out a nesting with a best utilization and a process planning for irregular shaped sheet metal products in single or pairwise operation and generate the blank layout and strip layout in graphic forms. Knowledges for a nesting and a process planning are extracted from plasticity theories, relevant references and empirical know-hows of experts in blanking industries. This provides its efficiency and effectiveness for nesting irregularly shaped sheet metal products.

This paper describes the process planning system of a computer-aided design of blanking and piercing for irregularly shaped sheet metal products. An approach to the system is based on knowledge-based rules. The process planning system is designed by considering several factors, such as the complexity of blank geometry, production feasibility of products, and punch profile complexity. Therefore this system which was implemented production feasibility check and strip layout module can carry out a process planning considering a production feasibility area of both internal and external features, a dimension of blanked hole, a coner and a fillet radius for irregualrly shaped sheet metal products and generate the strip layout in graphic froms. Knowledges for process planning are extracted from plasticity theories, handbooks, relevant references and empirical know- hows of experts in blanking companies. This provides powerful capabilities for process planning system of irregularly shaped sheet metal products.
