지식경영은 1990년대의 중요한 이슈로서 기업사회에서 폭발적으로 나타날 개념이다. 본고에서는 지식경영의 배경 및 정의, 지식경영 분야를 지배하는 주요 지배그룹과 테마 등 주요 개념과 이슈들을 살펴보았다. 특히 명시적 지식, 암묵적 지식 및 지식 인프라를 통합하는 도형적 모델을 제사하고, 모델의 중요한 특성을 상세하게 검토하였다. 또한 능률적인 지식경영시스템의 구축방법과 전형적인 사례 및 사서의 역할을 간략히 살펴보았다.

The aims of this study were to validate the Occupational Basic Competencies of Fisheries and Maritime High school. Fisheries & Maritime key competencies were defined as the abilities that include the essential knowledge, skills, attitude, and experiences required for the workforce on the fisheries and maritime job condition. This research collected preliminary data from 1,113 fisheries & maritime high school students. Data were analyzed to obtain reliability and validity analysis. The results of the study were as follows; First, fisheries & maritime key competencies were divided into 6 elements. Second, fisheries & maritime key competencies were consisted of marine vocational ethics, marine information capacity, marine elementary knowlegde, marine safety management skill, management & utilization of marine life and marine consciousness. Third, Cronbach-${\alpha}$ proves that the scale developed in the study is reliable. In consequence, the results of this study help to reconceptualize fisheries & maritime and apply the scale to measure students in high school settings.

Password-based authentication key exchange (PAKE) protocols in the literature typically assume a password that is shared between a client and a server. PAKE has been applied in various environments, especially in the “client-server” applications of remotely accessed systems, such as e-banking. With the rapid developments in modern communication environments, such as ad-hoc networks and ubiquitous computing, it is customary to construct a secure peer-to-peer channel, which is quite a different paradigm from existing paradigms. In such a peer-to-peer channel, it would be much more common for users to not share a password with others. In this paper, we consider password-based authentication key exchange in the three-party setting, where two users do not share a password between themselves but only with one server. The users make a session-key by using their different passwords with the help of the server. We propose an efficient password-based authentication key exchange protocol with different passwords that achieves forward secrecy in the standard model. The protocol requires parties to only memorize human-memorable passwords; all other information that is necessary to run the protocol is made public. The protocol is also light-weighted, i.e., it requires only three rounds and four modular exponentiations per user. In fact, this amount of computation and the number of rounds are comparable to the most efficient password-based authentication key exchange protocol in the random-oracle model. The dispensation of random oracles in the protocol does not require the security of any expensive signature schemes or zero-knowlegde proofs.
