인터넷 사용의 증가와 함께 점점 확대되는 인트라넷 및 익스트라넷 환경에서 사용자 인증 과정은 필수적인 요소이다. 이런 환경에서의 인증 과정에 있어 현재 사용자 편의와 보안을 위한 단일 인증 시스템이 널리 사용되고 있다. 본 논문에서는 단일 인증 시스템에서 사용되는 인증 기법을 사용자의 신원을 증명할 수 있는 매체(증거물:witness)에 따라 사용자가 아는 정보(something known by user), 사용자가 소유한 정보(something possessed) 그리고 사용자가 지니고 있는 정보(something embodied)로 분류하고 또한 인증 기법의 보안 강도에 따라 약한 인증(weak authentication) 기법과 강한 인증(strong authentication) 기법으로 나누어 분석한다. 인증 모델의 분석은 우선 단일 인증 시스템과 유사한 몇 개의 인증 모델을 먼저 분석하고 그 다음에 인증 시스템의 적용 환경, 인증 시스템의 인증 위치 그리고 인증 모델이 포함되는 시스템 계층에 따라 인증 모델을 분류한 후 각 인증 모델의 특징에 대하여 분석한다.

In this paper, fluorescent lamp on/off control and luminous intensity used an power line communication and remotely will be able to control system design. Embodied the respectively illumination equipment and tools by the network using PLC. In order to remote control and on/off of illumination equipment, luminous intensity composed a server. Will convert a previous analog system with digital system and the possibility witch will reduce an error ratio was. Consequently will be able to simplify a circuit.

A new constant growth technique to conserve an initial grating height of V-groove AlGaAs/InGaAs quantum nanostructures above 1.0 $\mu\textrm{m}$ thickness has been successfully embodied on submicron gratings using low pressure metalorganic chemical vapor deposition. A GaAs buffer prior to an AlGaAs barrier layer on submicron gratings plays an important role in overcoming mass transport effects and improving the uniformity of gratings. Transmission electron microscopy (TEM) image shows that high-density V-groove InGaAs quantum wires (QWRs) are well confined at the bottom of gratings. The photoluminescence (PL) peak of the InGaAs QWRs is observed in the temperature range from 10 to 280 K with a relatively narrow full width at half maximum less than 40 meV at room temperature PL. The constant growth technique is an important step to realize complex optoelectronic devices such as one-step grown distributed feedback lasers and two-dimensional photonic crystal.

A person does communication between each other using language. But, In the case of disabled person, call not communicate own idea to use writing and gesture. We embodied communication system using the ERG so that disabled Person can do communication. After feature extraction of the EEG included facial muscle, it is converted the facial muscle into control signal. and then did so that can select character and communicate idea.

중국은 다양한 소수민족으로 구성된 국가이다. 이처럼 풍부하고 다채로운 소수 민족문화는 애니메이션 창작 분야에서 무궁무진한 작품 소재로 사용되고 있다. 1980년대에 위구르족의 민간소재를 바탕으로 제작 된 스톱모션 애니메이션인 <아반티 이야기, 1979>는 위구르족의 문화와 전통을 잘 표현하였다. 이에, 본 논문은 스톱모션 애니메이션 기법으로 제작된 <아반티 이야기, 1979>에서 어떻게 위구르족의 문화와 전통 의상을 표현하고 중국문화와 연관성이 있는지, 그리고, 문화원형을 어떻게 현대적으로 해석하였는지 알아보고자 한다.

This paper examines the process of embodied technology spillovers in terms of supply and demand of technology For the purpose, this paper develops a consistent framework to estimate intersectoral R&D spillovers, and to pinpoint the sectors that are the most important for innovative activities and the sectors that produce most technologically intensive products. Based on an input-output framework, the technology intensity of fourteen sectors and the interaction between the sectors in terms of technology spillovers are measured. The results indicate that knowledge-based service sectors are highly supply-pulling and value-additive, but low in terms of employments. The study found that computer services, telecommunications, technology services, and art-related services are the most technology intensive sectors.

Recent issue of optical actuator is applying to mobile device. It leads actuator to become smaller than conventional type. This paper proposes the design of micro actuator plate spring and analysis of its vibration characteristic. Considering natural frequency of spindle motor, 1st and 2nd eigenfrequency of micro actuator must avoid its natural frequency. First, magnetic circuit is designed by using fine pattern coil and magnetic force is acquired by simulation program. Then, concept design is achieved by topology optimization. From concept design, micro actuator plate spring is embodied through DOE(design of experiment). Finally, considering vibration characteristic simultaneously, optimal plate spring design is determined by RSM(response surface method).

Generating fractal images by graphing calculators such as TI_92 combines several important features, which convey the excitement of a living, changing mathematics appropriate to secondary or post-secondary students. The topic of fractal geometry can be illustrated using natural objects such as snowflakes, leaves and ferns. These complex and natural forms are often striking fantastic and beautiful. The examples highlight the fact that complex, natural behaviors can result from simple mathematical rules such as those embodied in iterated function systems(IFS). The visual splendor beauty of fractals, in concert with their ubiquity in nature, revels the intellectual beauty of nonlinear mathematics in a compelling way. The window is now open for students to experience and explore some of the wonder of fractal geometry.

The purpose of this thesis is to make clear particulartity of young adult generation which leads industry in their demands so that fashion trends are foresaw, and to describe style of costume satisfied with picture of new male. This thesis is to consider young adult style of costume in terms of double root described by W$\ddot{o}$lfflin in the internal meaning and the external form, so as to analyze their unique style. In conclusion, domestic young adult style of costume is embodied in the internal meanings of individuality, aestheticism and new classicism in terms of the external forms which means body-priority-form by open-form, whole-form, integration-form, rounded-form, indeterminate-form. With these results, domestic fashion industry is demanded to be from classic to modern expressions so as to be reflected in sophisticated masculinity of young adult.
