  • Common Maritime Data Structure (CMDS) is commonly used by shore and ship users in e-Navigation data domain. In the overarching of e-Navigation architecture, IHO uses S-1XX, a digital exchange standard for next-generation marine information, as data exchange standard. The current CMDS has the advantage of intuitively recognizing the overall structure of e-Navigation. However, it has disadvantage in that it does not allow stakeholders to easily understand benefits that e-Navigation can provide when implementing e-Navigation. In this study, the direction of improving existing system for effective e-Navigation implementation was proposed considering RCOs (Risk Control Options) with expected composition of ship/ shore/ communication system by sector.

  • Human papillomavirus (HPV), especially type 16 and 18, has been closely associated with carcinomas and uterine cevical cancer, recently. From in vitro assays, E6 and E7 genes of HPV16 are closely linked with transformation of cell lines of rodent fibroplasts. However, the transforming activity of E6 and E7 genes of HPV type 16 in vivo has not been fully elucidated. For explaining this mechanism, we prepared a expression system with the promoter of mouse mammary tumorvirus long terminal repeat and E6E7's open reading frames. This expression system was introduced in rodent cell lines, No. 7, 3Y1 and shown normal transforming abilities. And, we produced transgenic mice with E6, E7 expression system. These transgenic mice were confirmed from Southern blot analysis. One male of them was observed enlargement of the testis after 5 months postdelivery.

It has led to the phenomenal growth in the use of web-based learning and experimentation with multimedia, video conferencing, and internet-based technologies. Many researchers are interested in the factors that affect to the performance of e-learning or e-learning services. In this sense, this study is aimed at proposing e-learning system reuse prediction models in which e-learner intention to reuse influence factors(i.e., system accessibility, system stability, information clarity, information validity, self-regulated efficacy, computer self-efficacy, perceived usefulness, perceived ease of use, flow, and parental expectation) affect e-learner intention to reuse positively. A web survey was conducted for the full members of the e-learning education institute A in Seoul, Republic of Korea, an exclusive e-learning company that provides real time video lectures via the desktop conferencing system. The web survey was conducted for 20 days from November 5, 2009, through the e-learning web site of the company A. In this study, three data mining techniques were used : the multivariate discriminant analysis, CART, and C5.0 algorithm. This study was conducted to provide the e-learning service providers, e-learning operators, and contents developers with marketing and management strategies for improving the e-learning service companies, based on the data mining analysis results.
