In this study, the survey from nationwide universities, e-learning service companies, and students who take e-learning courses was proof-analyzed. Sufficiency, variety, usability, accessability, and interaction with instructors were the criteria for analyzing the effectiveness of e-learning education. For this, the factors about effectiveness of e-learning education between the SCORM contents users group and normal contents users group were compared and analyzed. The differences between those two groups were appeared.

전 세계적으로 유통되고 있는 가짜의약품으로 인하여 제약사들은 판매수익과 기업브랜드 이미지에 큰 피해를 입고 있으며 가짜 의약품을 복용한 소비자들은 생명에 위협을 받고 있는 실정이다. 이러한 가짜의약품의 유통을 근절시키기 위하여 세계 각국에서는 의약품의 생산에서부터 소비자에게 판매될 때까지, 즉 의약품 유통과정을 추적하여 가시성있는 이력관리를 할 수 있도록 RFID 및 barcode 등 IT기반의 e-Pedigree(electronic pedigree)를 법제화시키고 있지만 구체적이고 실질적인 구축방법이 제시되지 못하고 있다. 따라서 본 연구는 국내 제약산업의 유통합리화와 소비자 안전성을 제고시키기 위하여 RFID 기반의e-Pedigree 적용방안을 제시하는데 그 목적이 있고 더 나아가 세계 각 국가의 e-Pedigree 구축을 위한 참조모델 개발에 일조하고자 한다.

The benefits of an e-learning system will not be maximized unless learners use the system. This study proposed and tested models that seek to explain students' satisfaction withe-learning systems. A survey was performed at a women's college in Korea, where students experimentally could choose to register one same course either through e-learning or class-room learning. The questionnaire was filled up by students who took e-learning option. independent variables include expected benefits, familiarity with technology, social influence, and accessibility. Dependent variables include the level of satisfaction, academic achievement, and the amount of the use of systems.

We define some multi-type asset models derved from L$\acute{e}$vy proceses which emphasize coefficients of stochastic differential equations. Also these asset models can be represented by Doleance-Dade linear equations derived from jump-type semimartingales which are decomposed by various terms of time basically. For these asset models, we can construct optimal portfolio strategy by using filtered various information at each check time.

This is an introduction to a stochastic version of E. Cartan′s symplectic mechanics. A class of time-symmetric("Bernstein") diffusion processes is used to deform stochastically the exterior derivative of the Poincare-Cartan one-form on the extended phase space. The resulting symplectic tow-form is shown to contain the (a.e.) dynamical laws of the diffusions. This can be regarded as a geometrization of Feynman′s path integral approach to quantum theory; when Planck′s constant reduce to zero, we recover Cartan′s mechanics. The underlying strategy is the one of "Euclidean Quantum Mechanics".

The evolution of color CRT electron gun design over the past 40 years is addressed. Many milestones of CRT E-gun design are cited. For the future survival of color CRT the multi-beam group color E-gun and the recently announced multi-beam type index gun are suggested as the answer to the challenge of the next generation's requirements of low power and high performance color CRT

Usually offline sales depend on the promotion strategy to the consumer-type. But e-commerce has some difficulties in analysing the consumer-type. And providing products and services with differential approaches to the type. Therefore, this study is a kind of explore information to the consumer character-type.

This article describes the concept of Right Management of digital contents and the usage and protection of education contents. In this study, we introduce the position of DRM in the e-learning technology and propose a education DRM strategy compare to existing Commerce DRM and Enterprise DRM.
