The purpose of this study is to develop lesson plan and to evaluate its application for the chapter of 'family life and housing'in the class of Home Economics in the third grade of middle school through the application of the Universal Design. This study has been done in three phases : analysis. development. and evaluation phase. The results of this study were as follows : First. in the development of the concept of the Universal Design. the objective of learning aimed to build the housing and utilities for all family members. Moreover. the various learning materials such as computer program. video materials. and worksheets of the group work were utilized to enhance the effectiveness of the lesson plan. Second. the evaluation of the students was examined through the assessment of the concept of the design. and the degree of class participation of student at the end of class. The LT cooperative learning as an instructional method was perceived to be appropriate and the participation of the cooperative work was also enhanced. The use of the computer programs. and video tapes was considered to be useful. Third. the response of the teachers was found to be both positive and negative. Teachers'positive reactions indicated that the use of the Universal Design facilitated student's participation in class stimulating their motivations and creative ideas not only in the classroom but also in the real life as for the negative reactions. teachers perceived understanding of the concept of the Universal Design. the activities of the students and class hours were relatively shout. These should be added to by the further study with the teachers endeavor.

This paper deals with characteristics of universal motor of which parameters varying by stator turns and propose stator turns that has the highest efficiency. Stator turns variation results difference in current, impedance, power, torque and speed. We try to measure these data. The experimental results show the stator turns which this motor has the highest efficiency.

This paper addresses the vertical class fragmentation in distributed object-oriented databases. In the proposed vertical fragmentation, after producing the attribute fragment by partitioning attributes, then the method fragment is produced by gathering methods referring the attribute in each fragment. For partitioning attributes, we define query access matrix(QAM) and method access matrix(MAM) to express attributes that method refers, and extend QAM, MAM and attribute usage matrix(AUM) to universal class environment for representing relationship among other classes through class hierarchy and class composite hierarchy.

The variety of learners include students with disabilities and general students, and an ongoing focus of inclusive education research is non-discrimination. As part of integrated education, UDL (Universal Design for Learning) for students with disabilities supports a practical approach, participation, and advancement to improve learning opportunities for all students. The purpose of this study was to examine the effects of using UDL in science classes. The dependent variables of this study were academic achievement in science, scientific attitude, and scientific motivation. In this study, the experimental groups were 9 people in the 5th grade and 11 people in 6th grade. The experimental groups were taught science class using UDL. In order to analyze the learning outcomes, the structure equation model was performed. The results of this study were as follows: First, the science achievement of learning outcomes of the science class applying UDL directly affected both scientific attitude and scientific motivation. Second, the scientific attitude of learning outcomes of the science class applying UDL directly did not affect scientific motivation. According to these results, learning outcomes for science achievement of the science class applying UDL showed that UDL affected both general students and students with disabilities. To summarize the analysis of learning outcomes, science achievement directly affected both scientific attitude and scientific motivation while scientific attitude did not affect scientific motivation. This study offered a specific implementation method for integrated education. Using the structure equation model for analyzing the effect has more significance.

본 논문은 신경망 근사 해석 모델 개발을 궁극적인 목적으로 하는 기초적 연구로서, 기존의 수치해석 알고리즘과의 성능 비교를 통하여 신경망 알고리즘의 특성과 역할을 수치해석의 관점에서 정확히 판단하는데 목적이 있다. 신경망 알고리즘을 변형하여 선형 연립 방정식의 해를 구하는 두가지 방법을 제안하였고, 회귀분석, 보간법과의 비교를 통하여 광범위한 근사자(universal approximator)로서의 역할을 보였다.

We propose a universal image processor for a-Si TFT LCD of UXGA class that can display the full screen on the LCD panel with low resolution of video sources such as NTSC, VGA, SVGA, XGA, and SXGA by using the proposed interpolation filter. In addition, we propose a real-time contrast controller for image improvement of multi-gray scale image. The operation of the proposed methods has been verified using Synopsys VHDL and computer simulation. Results show that the proposed methods might be suitable for a UXGA LCD controller for real-time image improvement.

Over the past few years Korea has achieved rapid economic growth, while the deepening polarization of income has negatively affected Korea economy and society. It can be the reason of this negative effect on economy that the increased income by the economic growth has not been distributed socially, but overly focused on one part of social class. One of the important and powerful solution of social polarization could be the strengthening of the income distribution. In these circumstances, the social interest and discussion on the universal welfare system and on the basic income as the means of income redistribution have been increasing. In this study, a system dynamic analysis was conducted to find how an universal cash payment as basic income providing cash benefits impacts on the promotion of consumption in private sector, of local jobs and of local economic organizations. Recently, the poor energy consumption ability of energy poverty became one of the social problems. Also it was analysed how an energy payment-in-kind as basic income influences on the energy consumption of the region, the energy production capacity, the promotion of local energy. The universal cash payment and energy payment-in-kind as the basic income policy showed similar and positive effects on the local economy system and on the local energy system respectively.

In this paper, we present a new class of attacks against an anonymous communication protocol, originally presented in ACNS 2008. The protocol itself was proposed as an improved version of ModOnions, which exploits universal re-encryption in order to avoid replay attacks. However, ModOnions allowed the detour attack, introduced by Danezis to re-route ModOnions to attackers in such a way that the entire path is revealed. The ACNS 2008 proposal addressed this by using a more complicated key management scheme. The revised protocol is immune to detour attacks. We show, however, that the ModOnion construction is highly malleable and this property can be exploited in order to redirect ModOnions. Our attacks require detailed probing and are less efficient than the detour attack, but they can nevertheless recover the full onion path while avoiding detection and investigation. Motivated by this, we present modifications to the ModOnion protocol that dramatically reduce the malleability of the encryption primitive. It addresses the class of attacks we present and it makes other attacks difficult to formulate.

최근들어 UMTS(Universal Mobile Telecommunication System)는 3세대 무선망의 표준으로 인식되고 있고 DSCH(Down-link Shared Chanel)는 UMTS에서 매우 효율적인 다중화 방안으로 고려되고 있다. 그러므로 UMTS에서의 DSCH를 위한 효과적인 패킷스케줄링 알고리즘 개발에 대한 연구가 필수적이다. 본 논문은 UMTS의 DSCH를 위한 개선된 패킷스케줄링 알고리즘에 대하여 기술한다. 이 알고리즘은 최대 링크 이용율을 위하여 이동호스트채널상태를 고려하며, 동시에 장기적으로 공정성을 얻기 위해 3등급 트래픽에서의 지연 한계치와 4등급 트래픽의 처리율을 함께 이용한다. 알고리즘의 타당성을 보이기 위하여 PARSEC을 이용한 모의실험을 수행하였다. 모의실험 결과는 이 알고리즘이 무선링크 이용율과 공정성 두 가지 측면에서 적적한 타협(trade-off)을 통하여 개선된 결과를 얻을 수 있음을 보여준다.
