With the increasing number and variety of internet users as well as the development of internet technology, web contents have been taking a more comprehensive, integrated, and practical form. This change has brought to our attention the importance of the information architecture and menu design, both of which are required for the users to navigate vast amount of data promptly, correctly and easily for effective communication in the web sites. In this study, web sites were categorized by the service levels provided to the users, and sampling was performed accordingly. Then, information architecture, the layout and the presentation of the menu design were analyzed. The result of the analysis show that there are distinguishable characteristics in how the menus were expressed and designed, and that these characteristics reflect the users' characteristics in the web interface menu design. With the result of this study, we present a guideline for information architecture and web interface menu design, which reflects user characteristics thereby strengthening usability. Using this guideline, we expect the development of web interface design which should support more efficient communication on the web.

In many construction projects, such as dams, highways, airports, buildings, industrial plants, and sewerage and drainage systems earthmoving operation is defined the movements of a certain quantity of earth to alter the surface configuration or conditions so that projects requirement can be met. Accurate calculation of travel time is essential for determining productivity of earthmoving operations, and for ultimately selecting the most cost-effective fleet configuration for executing the work. Also transportation work that utilizes dump truck consists average So in the whole expenses earthmoving operation, and is an important cost factor for cost management. Therefore this study proposes a methodology for optimum transfer speen based on the analysis of factors affecting earthmoving operation in different road types by collecting the sources of dump truck running speeds and considering the main factors affecting the earthmoving operation.

This paper is to suggest policy issues to be done in the future health policy for the elderly, analyzing contents of results suggested in academic papers published in Journal of the Korean Gerontological Society. Number of Papers published in the Journal is 61, occupying most of papers related with chronic disease, medical expenditures and health delivery system except dental and psychiatric health. Method used to be analyzed is mostly random sampling among community inhabitants or hospital patients. Policy issues are as follows in case of being based in the above analysis results. Firstly, it is necessary that the development of health promotion specialized for the elderly be developed and activated. Secondly, it is necessary that the primary health care system specialized for the elderly be constructed. Thirdly, it is necessary that the subacute care system specialized for the elderly be constructed after acute care services. Finally, it is necessary that the health care system specialized for the elderly in need of long-term care be constructed also.

이 글에서는 블록체인이 미디어 서비스에 미칠 파장들을 유형별로 나눠보고 블록체인이 실제 미디어 서비스에 적용된다고 할 때 어떠한 부분을 전략적으로 고려해봐야 하는지 다뤄봤다. 요약해보자면 블록체인은 미디어 서비스에 적용될 경우에 1) 콘텐츠 구성물들의 저작권 명확화, 2) 생산과 소비 수치의 정확한 산출, 3) 콘텐츠 제작 유통 과정에서 공정한 배분과 분배, 4) 콘텐츠 소유권 인증과 관리의 안정성, 5) 공유 포맷과 방식의 다각화 등에 영향을 미칠 수 있다. 블록체인이 미디어 서비스에 적용될 수 있는 수준이라고 해서 미디어 서비스 산업에서 이를 무작정 수용할 수는 없는 일이다. 따라서 주로 고려해볼만한 사안으로 1) 업무 효율화가 이뤄지는가, 2) 합리적인 대가가 도출될 수 있는가, 3) 다양한 서비스 창출이 가능한가, 4) 기존에 경험되지 않은 서비스인가, 혹은 어떻게 체감할 수 있는가 등의 전략적 판단 기준들을 제시해보았다.

PKI 구축을 위한 노력이 전 세계적으로 진행되고 있는 가운데 PKI의 계층구조 유형에 따라 인증관리 정책, 인증서 형식 등의 서로 다른 PKI 구성요소를 가진 인증기관(CA)들이 각기 다른 곳에 분산되어 있다. 그러므로, 이러한 CA간의 상호인증 서비스를 어떻게 제공할 것인가를 고려해야 할 필요가 있다. 특히 상호인증 서비스를 제공하기 위한 인증정책, 정책매핑, 정책제한의 확장영역은 인증경로의 유효성을 검증할 때 검증의 성공과 실패에 중요한 영향을 미친다. 본 논문은 ITU-T X.509의 인증경로처리과정에서 정책과 관련된 부분을 살펴보고 ITU-T X.509 3rd Edition의 정책관련 문제점들이 ITU-T X.509 4th Edition에서 어떻게 개선되었는지 몇 가지 예를 통하여 제시하고 앞으로 인증경로처리과정이 어떠한 방향으로 확장되고 응용되어야 할지를 기술한다.

알려진 공격 방법에 대해서는 다양한 방법으로 공격을 탐지하여 적절한 대응을 할 수 있는 반면 알려지지 않은 방법에 의한 공격은 침입탐지 시스템에서 공격 자체를 인식하지 못하므로 적절한 대응을 할 수 없게 된다. 따라서 비정상행위에 대한 탐지를 위해 데이터마이닝 기술을 이용하여 새로운 유형의 공격을 추출하고자 하였다. 특히 대용량의 데이터에 공통적으로 나타나는 순차적인 패턴을 찾는 순차분석 기법 중 PrefixSpan알고리즘을 적용하여 비정상 행위 공격을 탐지할 수 있는 방법을 제시하였다.

User authentication is the first step to network security. There are lots of authentication types, and more than one authentication method works together for user's authentication in the network. Except for biometric authentication, most authentication methods can be copied, or someone else can adopt and abuse someone else's credential method. Thus, more than one authentication method must be used for user authentication. However, more credential makes system degrade and inefficient as they log on the system. Therefore, without tradeoff performance with efficiency, this research proposed user's behavior based authentication for secure communication, and it will improve to establish a secure and efficient communication.

As the tourists of ecotourism are increasing, the supply for detailed information on tourist attraction is also significantly increasing. As a result of survey given to tourists, it showed that they are more interested in natural ecological resources rather than history or culture among resources of ecotourism and pointed out that more information on the region needs to be supplemented. In order to provide accurate, detailed and standardized information to tourists, ecotourism resources were categorized as experience type from the position of consumer and ecological resource type. And the category of experience is again divided into 4 types - nature, education, communication and adventure. Moreover, after developing the web-based homepage for it, the research proposed the cases of Tae-an area and Ulleungdo Island. If the problems from test operation are supplemented, it is expected to suggest the standard of mobile based digital storytelling technology in the field of ecotourism.

Rapid business and technology changes drive many organizations to seek better solutions and many of them believe that Information Technology is an essential tool to cope with turbulent environment. Companies began to think ERP system as an effective alternative for IT-based process innovation and integrated information system. But each ERP system has a specific business model and technical structure, unlike in-house developed systems. Moreover implementation of ERP system accompanies transformation of business processes at company level including radical changes in information technology. Therefore, to implement ERP system successfully appropriate and careful selection of ERP system which is adequate for company's objectives and environment must be considered. In this research, four types of changes expected by ERP implementation were suggested. Each type of changes was determined by desired level of changes in business process and information technology.

This study analyzed subjective cognitive types of culinary majors by applying TBL of cooking practice subjects, and applied Q methodology to multifaceted analysis of subjective cognitive types of learners. For the analysis of the study, interviews were conducted for college students majoring in cooking, and the survey was conducted in the order of constructing the Q population, selecting P-samples, classifying Q, interpreting the results, conclusions, and discussion. A total of four types were derived from the type analysis, and each was named according to its specificity as follows. Type 1 (N = 8): Cooperative Learning Effect Types, Type 2 (N = 8): Problem Solving Ability Effect Types, Type 3 (N = 6): Self Directed Learning Effect Type, Type 4 (N = 6): Individual Practice Preference Type analyzed for each unique feature type. It is expected that through the results of the study, it is expected to provide important implications that can help in the study of similar teaching methods in the future by fostering talents who can increase the needs of the industry and social stress.
