The purpose of this study was to identify web designer's knowledge organization for WWW. Linked web sites were investigated in public library web pages. Independent variable was the supervised offices of public libraries and dependent variables were the web sites of type of public libraries, supervised offices of public libraries, and employment information. Results showed that special library and supervised office web sites were linked differently by public library web pages differently based upon supervised offices. This difference was resulted from geographical factors and types of information on the web sites.

The Korean government, as of last year, is attempting to introduce a competitive system in the rail-market. However there are some pertinent issues which need to be addressed in order to select the best possible organization for optimum railway traffic control. As there are no standard guidelines in selecting an agency, objective evaluation factors need to be properly applied to ensure the best possible decision is made. Through literature review and various interviews with experts, appropriate criteria were selected to evaluate the suitability of each potential operator. As generally mentioned, both safety and efficiency play vital roles in the selection process but in addition, there are other factors such as security and fairness, which also need to be considered. The individual weight of these factors were calculated by the AHP, in which three groups of experts were interviewed to acquire their expertise. According to the results, as a potential operator, the score of a railway operating company and the management cooperation of railway is 2.75 and 3.85, respectively. In the future, in preparation towards becoming a competitive rail-market, this research is expected to assist in choosing the best party to control the rail traffic system.

This study analyzed the financing ratio by operation fund financing method and their impact on management performance according to the establishment operation management entity of the medical institution. For the analysis method, ANOVA, logistic regression, and regression analysis were conducted using financial information registered with HASPA.The results of the study, The ratio of gross revenue to operating funds differed significantly depending on the establishment operation management entity. In addition, it was found that the financing ratio of each operation fund financing method was significantly related to the management results(deficit, surplus), and the impact of the operation fund financing method on management performance differed according to the establishment operation management entity. As a result, the management of operating funds of medical institutions is deemed appropriate to apply cost management first considering the ratio of revenue to operating funds, and then to utilize internal operating funds.

대부분의 안전한 운영체제는 주체와 객체에 보안 등급을 부여하여 운영하는 다중등급 정책(MLP: Multi-Level Policy)을 수용하고 있으며, BLP 모델은 이 정책을 표현하는 검증된 대표적인 모델이다. 하지만 이러한 다중 등급 보안 운영체제들은 접근 주체인 프로세스가 접근 객체로서 존재하는 등급화 된 프로그램을 실행 시 새로운 프로세스를 위한 보안 등급을 부여해야 하는데, 접근 주체와 접근 객체의 보안 등급이 다를 경우 보안 등급 결정 문제가 발생하며 정보보호의 목적에 위배되는 결과가 발생한다. 이에 본 논문에서는 위에 언급된 문제를 해결할 수 있는 방안을 BLP 모델 측면에서 고찰한다.

수요 반응 프로그램은 크게 인센티브 기반 수요 반응 프로그램과 가격 기반 수요 반응 프로그램으로 나눌 수 있다. 인센티브 기반 수요 반응 프로그램은 용량 요금 형태의 보상금을 지급하고 전력 시스템의 안정적 운영을 위해 긴급 상황 시, 이벤트를 통해 호출 됨으로써 중요성이 더욱 부각되고 있다. 신뢰도 수요 반응 자원들은 운영주체와의 사전 계약 시, 자신의 월 또는 연간 사용 한도를 정하고 계약을 하게 된다. 이는 빈번한 수요 자원 호출로 인해 수요 자원 보유자가 효과적으로 반응하지 못하게 됨을 방지하기 위함이다. 본 논문에서는 이러한 수요자원의 최대 사용 횟수를 고려하여 신뢰도 수요 반응 프로그램의 스케줄링 방법을 제안하였다. 본 스케줄링 방법은 각 이벤트별 필요 수요 자원량과 각 수요 자원들의 비용을 고려하여 특정 기간동안의 계획을 수립하는 것으로써, 현재 널리 이용되는 단기 스케줄링과 비교하였을 때, 운영주체의 비용을 절감할 수 있게 된다.

다중등급보안(MLS: Multi-Level Security)기반 안전한 운영체제는 정보의 흐름을 안전하게 통제하기 위하여 주체 및 객체의 보안등급변화를 허용하지 않는다. 하지만 안전한 운영체제의 사용성(Usability) 측면에서 주체 및 객체의 보안등급변화는 고려되어야한다. 주체 및 객체의 보안등급변화에 관련된 요구사항은 시스템의 환경 및 보안정책에 따라 다양하게 발생할 수 있고, 이러한 보안등급변화에 관련된 다양한 요구사항들은 모두 해결하기 어렵다. 뿐만 아니라, 기존 접근통제 메커니즘은 보안등급변화에 관련된 요구사항을 해결할 수 없다. 따라서, 본 논문에서는 MLS 기반 안전한 운영체제에서 빈번하게 발생할 수 있는 보안등급 변화에 관련된 요구사항 중 특히, 시스템의 환경에 의해 주체의 보안등급이 하강되었을 때 해당 주체가 생성했던 객체들의 안전한 보안등급 하강과 관련된 보안요구사항을 해결할 수 있는 접근통제 메커니즘을 설계하고 구현한다.

The objective of this study is to provide the basic data for the efficient operation of industry-academia partnership apprenticeship school, by analyzing the interest in the relevant policy, targeting the interested parties of school and corporation as the two main subjects operating the industry-academia partnership apprenticeship school. Using the Concerns-Based Adoption Model(CBAM) used for understanding the interested parties' interest in the adoption of a certain new changing. In the results of analysis, first, currently, the operating subjects of industry-academia partnership apprenticeship school showed the similar interest with the pattern of nonusers. In other words, currently, based on the curiosity about the relevant policy, they are interested in which roles they should perform for the successful operation. Second, when dividing the operating subjects of industry-academia partnership apprenticeship school into school parties and corporate parties, the results of examining the differences in the interest of each subject are as follows. First, in the stages except for the Stage 0(indifference), the interest of school parties was relatively higher than the one of corporate parties. It might be because the school's role is bigger in the operation of industry-academia partnership apprenticeship school, contrary to the advanced countries. In other words, in case of school parties, the overall and general understanding of the relevant policy is premised, so that their interest of each stage is higher than the one of corporate parties. Especially, the Stage 5(cooperative interest) showed the biggest differences. As the cooperation between industry and academia is the success factor of the relevant policy, it would be necessary to implant the concrete measures for industry-academia cooperation in school parties, and also to implant the importance of industry-academia cooperation in corporate parties. Next, both operating subjects showed the lowest intensity in the Stage 4(consequential interest). It means that the operating subjects' interest in the evaluation of apprenticeship students is relatively low.

As international trade has been increased, the competition of major ports is getting hard. The objective of this competition is that to get more cargoes, so port managements and operators are struggling to obtain cargoes. In addition the competition structure has classified several forms bemuse of specialization, integration and subdivision of port players. In this paper, therefore, we analyze the change of competition structure by port players' development characteristics. In the result of this study, competition structure is divided into five groups as among nations, among ports, among container terminal operation companies, among global container terminal operation companies and among container terminal operation companies operated by shipping companies. And they have showed not only competition but also co-operation partly in order to get strategic position.
