IT(Information Technology) 제품의 보안 기능을 평가하기 위하여 서로 다른 체계를 이용할 경우 평가를 위한 이중의 비용 소요와 추가의 시간 소모 등의 문제점을 해결하기 위하여, 미국, 영국, 호주 등의 선진국들은 국제 간에 상호 인정이 가능한 공통평가기준(CC: Common Criteria)에 대한 연구가 활발히 진행되고 있다. 현재 우리나라도 국제상호인정협정(CCRA)에 가입을 준비중에 있으며, 다양한 IT 제품으로 평가 제도의 확대를 준비하고 있다. 본 논문에서는 미국, 영국, 호주의 CC 체제 하에서 평가된 정보보호 제품들의 특성을 분석하고, 이를 근거로 우리나라 IT 제품의 보안기능 평가에 적용 가능한 분류 체계를 고찰해 본다.

This paper aims to analysis sectoral innovation patterns of technological innovation and localized knowledge spillover in Korean manufacturing sector. Sectoral innovation system approach proposed that the specific pattern of innovative activity and knowledge spillover in an industry can be explained as the outcome of different technological regimes. Technological regime is defined by the particular combination of technological opportunities, appropriability of innovations, cumulativeness of technical advances and properties of the knowledge base. Based on a sample of 2,882 firms in manufacturing sector, this paper provides empirical estimates of the relationships between firm's product innovation and localized knowledge spillover. Results of the analysis provide considerable support to the hypothesis that firm's product innovation and localized knowledge spillover are related to the nature of the underlying technological regime. In the industry based on the tacit and specific knowledge, firm's product innovation is positively related to the localized knowledge spillover. This paper also shows that high stability in the ranking of innovators are related to high degrees of cumulativeness and appropriability.

본 연구는 웹 기반 감성데이터베이스구축 및 보급을 위하여 국내의 감성 관련 주요 연구 결과 및 감성 자료를 수집하고 주요 감성 지표를 개발하였다. 개발된 감성 지표는 사용 적합성 지표로서 수집한 감성 자료들 중 사용 적합성에 관련된 감성 자료를 선별하여 이를 물리적/객관적 적합성 관련 지표와 주관적 적합성 관련 지표, 개발된 측정 시스템, 감성 정보물로 분류하였다. 물리적/객관적 지표는 다시 환경 지표, 생리 지표, 제품설계 지표, 평가척도 지표, 제품평가 기술 지표로 분류 등의 세부지표로 분류하고, 주관적 지표는 언어 지표, 묘사 지표, 심리 지표, 인지 지표로 다시 나누어 분류하였다. 개발된 제품, 측정 시스템, 또는 시뮬레이터 둥은 개발된 측정 시스템으로 분류하고 그 밖의 감성공학적으로 중요한 자료 및 정보는 감성공학 관련 정보물로 분류하였다. 분류한 지표는 전문가의 검증을 통해 타당성을 확인한 후 감성 데이터베이스로 구축될 예정이다. 이를 위하여 전반적인 감성 자료 관리 시스템을 통한 효과적인 감성 자료 관리체제 구축과 감성 자료의 공유가 뒤따라야 할 것이다.

An academic advising program has been initiated by Yonsei University to help first-year students formulate sound educational and career plans. We analysed the program on the basis of organizational models of advising of American colleges. Represented by University college and academic advisor, it can be categorized as a compromised system of Split and Total-Intake models.

The applications program that running on Operating System has high dependence. Because environment of OS and standard libraries that supports are different. For those reason, Applications that perform the same function should be implemented in accordance with the new operating system. This results in a temporal and economic waste not only in subsequent maintenance of application but also in management. Even though, to solve this problem Cygwin or MinGW has been distributed, they do not support the portability of the application but provide a virtual environment and the tool. Therefore, in this paper, we design the wrapper format interface middleware using the POSIX and standard C library to support the application performing the same function on virtual environment and without code modification. The middleware can be selectively loading the API that is classified by basic and extend. This allows to managing the application size efficiently. Also, perform the comparative experiments and performance evaluation for application, on equipped with the Interface Middleware Linux, Unix, Windows and on Cygwin.

Technical innovation on multimedia data processing brings us new multimedia services. Multimedia services are classified into five groups : TVs, computers, telecommunications, periperals, and softwares. This paper surveys on the services in various aspects and, in particular, computer areas are discussed in detail. To provide the services, major subsystems such as highspeed networks, operating systems, intelligent agent based user interfaces are discussed. In particular, multimedia operating systems are the most actively investigating research area as an infrastructure of multimedia computer systems to provide integrated multimedia services. So, the trends of new multimedia operating systems are analyzed and COSMOS (Collaborative Object Sharing for Multimedia Operating System) multimedia group presentation is discussed. The characteristics, model and abstract data structure of COSMOS is described. The performance analysis of 3 person conference system using audio, video and shared graphic editor on COSMOS shows that taking integrated multimedia operating system approach leads changing of new multimedia service environments.

Recently it is supposed to be a shift to regional geography. To understand the emergence of the new regional geography, It must be remarked that the progress of capitalist production and consumption change our conceptional apparatus such as representation of space. Region is one of the important mode of representations of space and time. In the Fordist capitalism of 20th century, development is regarded as diffusion of capitalist expansion of western worlds. State must support capitalist growth through regional policies which include constructing of infrastructure and regionalization of spatial division of labour. The regional development theories contributed as ideology and policy tools for state intervention. The region was simply one of the most logical classification tools of organizing geographical informations. In the theories of regional development, the concept of region was reduced to the formal unit of classification. As the transition from Fordism to flexible accumulation, the region is again acquiring its 'identity' and 'authenticity'. In this tendency of the revival of region, it is expected that good achievement could be made in the field of regional geography through relevant research methods. It is also believed one of the available means are historical approaches to the cultural and ecological regions. The historical approaches to cultural and ecological regions are not only correspondent with cultural development strategies of local governments, but also could convey regional identities through both narrativization of place and aestheticization of landscape.
