According to arriving convergence environment which can create new value-added converged between industry and ICT technology, It has made economic growth and improve the quality of life. However this convergence environment provide not only advantage but also various security problems resulting from generating converged security threats. For resolving this security problem, we need to approach to security problem in the integrated view not the fragmentary view which cover only technical approach. So This study developed security governance framework which can manage trustful security governance in multidimensional view which cover strategy, managerial/operational and technical view. Therefore this framework can construct trustful security management system which can help top management team to engage in security management directly and organizational member to perform security activities and have responsibility for themselves as suggesting single standard for security management.

태양광산업의 value chain중 up-stream쪽인 고순도 실리콘산업은 셀, 모듈, 시스템 쪽에 비하여 영업 이익률이나 부가가치 측면에서 매우 높은 성장성을 현재 보여주고 있으며 최근 원자력산업의 안전성 문제가 대두됨으로 인하여 태양광수요가 전 세계적으로 증대되는 경향을 나타내어 태양광용 실리콘의 수요가 확대됨과 아울러 spot시장에서의 가격 또한 상승하고 있다. 이런 관점에서 잉곳 및 웨이퍼 가공 중에 발생하는 고순도 실리콘 폐기물의 재활용 이 다시 주목받고 있다. 태양전지 웨이퍼(wafer)용 소재는 6N급 이상의 결정질 실리콘 잉곳(ingot)이 주를 이루며, 고효율의 셀을 제조하기 위해서 단결정 실리콘 잉곳이 많이 사용된다. 실리콘 단결정을 육성하는 방법에는 Floating zone 법, Czochralski 법, Bridgeman 법, CVD 등 매우 다양하다. 이 중 Czochralski 법은 전체 생산량의 대부분을 차지하고 있는 방법으로, 용융액에서 결정을 인상하여 ingot을 제작하는 방법이다. 그러나 대량의 전기에너지를 소비하여 제작되는 고순도의 실리콘 단결정 잉곳은 후 가공공정에서 그 절반 이상이 분말(powder) 및 슬러지(sludge)로 폐기되므로, 자원의 재활용 및 환경오염 측면에서 주요과제가 되고 있다. Czochralski 법으로 제작된 ingot의 경우 그 표면이 매끄럽지 못하여, 웨이퍼 단위의 가공 시 형태가 진원이 될 수 있도록 표면을 미리 연마(grinding)하는데, 이때에도 미세 분말이 다량 발생하게 된다. 본 연구에서는 이러한 고순도 단결정 실리콘 ingot의 연마 가공공정에서 발생한 미세 분말을 용해하여 보았다. 진공 챔버(chamber) 내부에 유도가열 코일과 냉도가니로 구성된 장비를 통해 전자기유도가열을 이용하여 실리콘 분말 폐기물을 용해하고, 그 시편을 ICP-MS 및 비저항 측정을 통해 분말 의 특성을 조사하여 재활용 가능성을 검토해 보았다.

다가오는 21세기를 대비하여 많은 나라들이 정보와 지식을 확보함으로써 국제적 경쟁력을 갖추기 위해 노력하고 있다. 특히 지식의 공급원천인 기초과학에 대해서는 그 본질을 훼손하지 않으면서 기초과학을 국가경쟁력 강화에 어떻게 연계시키느냐에 초점을 맞추어 정책을 수립하고 있다. 21세기를 앞둔 지금 우리의 바람직한 기초과학정책의 방향은 우리의 현실을 바탕으로 한 실용적이면서, 기초과학이 지니는 특성을 충분히 감안한 것이어야 한다. 따라서 21세기 우리의 기초과학정책이 추구해야 할 목표를 다음과 같이 3가지로 설정하고자 한다. 첫째 지식의 증진, 둘째 과학기술인력의 양성, 셋째 경제성장과 삶의 질 향상에 기여이다. 이 세 가지 목표는 상호 독립적으로 존재할 수 없으며 상호 밀접하게 연계되어야 한다. 이 세 가지 목표를 달성하기 위한 추진전략은 다음과 같다. (ⅰ) 기초과학에 대한 지속적인 정부지원의 강화 : 기초과학에 대한 지원은 정부가 중추적인 역할을 담당해야 하며, 창의적 연구와 학제간 연구에 대한 지원을 강화하여야 한다. (ⅱ) 연구와 교육의 연계를 통한 과학기술인력의 양성에 기여 : 창의적이고 수준 높은 연구를 통해 훌륭한 과학기술인력이 양성되어야 한다. 지식기반경제 하에서 훌륭한 과학기술인력은 미래의 우리 나라의 성공을 좌우하는 요소가 될 것이다. (ⅲ) 국제적 연계의 강화 : 우리 나라의 SCI 점유율은 1%에 불과하다. 국제적 과학기술연계를 통하여 세계의 과학기술지식에 접근하고 협력의 이익을 얻을 수 있어야 한다. (ⅳ) 프로그램 위주의 지원방식과 분야별 지원방식의 병행 추진 : 기초과학에 사용될 수 있는 자원은 한정되어 있으므로 해당 분야의 특성과 경제 사회적 요구를 감안하여 분야별 우선 지원을 병행하여야 한다. 분야별 우선 지원을 위해서는 분야별 전망보고서가 작성되어야 한다. 그러나 분야별 우선 지원 분야의 도출 및 이의지원은 창의적 연구에 대한 보완적 개념으로 이루어져야 한다. 선진국의 경우에도 우선 지원분야에 대한 연구비 배분은 5-10%사이이다. (ⅴ) 성과관리를 통한 지원효과의 극대화 : 기초과학의 지원에 있어서 그 성과를 특정한다는 것은 쉬운 일이 아니지만 연구비 지원효과를 극대화하기 위해서는 프로그램 평가를 통해 성과관리를 하여야 한다. (ⅵ) 효율적인 혁신시스템의 구축 : 혁신시스템의 효율적인 운영이 매우 중요하다. 이를 위해서는 첫째, 연구부문과 산업부문을 연결시킬 수 있고, 새로운 분야를 담아낼 수 있는 유연한 분야분류체계를 정립하여야 하고, 둘째 연구결과의 효율적인 활용이 이루어져야 하며, 셋째 연구지원기관간 연계시스템의 구축을 구축하여야 한다.

The exercise of police power for danger prevention gives top priority to the prevention of injury occurrence. However, the controversy over the concept of danger has hitherto focused on the limit establishment, namely which scope is to be a target of prevention in the danger prevention area of the Police Law. After all, the police's duty for maintaining public peace and order is forced to be peformed through individual measures for danger prevention, and the preventive police action, which aims at the prevention of danger against the protection interest in the Police Law, can be performed on the premise of a precise understanding of danger in order to carry out a legitimate preventive police action. In addition, it examines the legal meaning in each constitution element by dividing the minimum common components of danger into loss, sufficient probability and time accessibility, and the interpretation problem of danger as uncertainty concept.

A clearly defined e-catalog (or product) information is a key foundation for an e-commerce system. A classification (or categorization) is a core information to build clear e-catalogs, can play an important role in quality of e-commerce systems using e-catalogs. However, as the wide use of online business transactions, the volume of e-catalog information that needs to be managed in a system has become drastically large, and the classification task of such data has become highly complex. In this paper, we present an e-catalog classifier system, and report on our effort to improve an e-catalog management process and to standardize e-catalogs for enterprises by use of automated approach for e-catalog classifier systems. Also we introduce some of the issues that we have experienced in the projects, so that our work may help those who do a similar project in the future.

The study aims to evaluate the outcomes of the Centers for Independent Living(CILs) demonstration program and to recommend future directions for CILs in 2006. The framework for the evaluation is a logic model, which facilitates outcome-based performance measurement. The measures associated with the logic model include input, activity, output, and outcomes. The data were collected by interviewing the executive directors of 10 CILs and conducting telephone survey with 231 consumers with disabilities. The study found that 69% consumers acquired new knowledge and skills for independent living. The study also revealed that 87% consumers experienced the positive changes in their lives and 83% consumers were satisfied with the services of the Centers. After using the services, consumers reported significant increases in self-confidence, and in the number and the level of involvement in the activities. In addition, the study found that the employment status of the consumers was improved, and the number of persons who were living in institutions was decreased. The study supports the advancement of policy to institutionalize Centers for Independent Living, and points to the importance of developing the capacity of the Association of Centers for Independent Living to ensure high quality services. In addition, it is suggested that the development of a manual for these services is necessary, and that services should be provided across disabilities and throughout the country, especially in rural areas.
