The purpose of this study is to analyze the characteristics of the media contained in textbooks for students with disabilities based on the information processing model, and to find ways to utilize library materials for class improvement for them. To this end, the media included in the in-depth learning activities of the Korean language textbooks of the 2015 revised special education basic curriculum were analyzed. As a result of the analysis, it was found that students with disabilities received information mainly through vision, process information through understanding, and use language intelligence to produce results. Specifically, they accepts learning contents through illustrations and texts, processes the contents based on understanding such as reasoning and explanation, and then uses linguistic intelligence such as writing and speaking to produce results. Based on the results of this analysis, a practical method to utilize library materials in the Korean language class of students with disabilities was proposed as follows. Developing a variety of input mediums based on reading stages and collection mapping for students with disabilities. Providing book materials through reading and listening. Teaching appropriate methodological knowledge to self-directly solve advanced learning activities. In addition, developing types of writing and writing strategies that can help various production activities.

자성유체는 자연에서 추출한 것이 아니라 자화성(Magnetizability)과 유도성(Flowability)을 동시에 갖도록 합성한 특수액체이다. 자성유체는 1960년대 중반에 미국의 NASA에서 처음 개발된 이후로 윤활, 밀봉, 감쇄, 의료 등의 분야에서 응용연구가 많이 진행되었기 때문에 고도의 정밀도를 요하는 항공, 우주산업, 컴퓨터와 반도체 분야 등에서 실용화가 크게 진전되고 있다. 특수물질일 자성유체는 전기적으로 도체인 10nm 정도의 미세한 자기입자(Magnetic particles)에 코팅을 한 후, 이것을 물, 탄화수소, 플루오르카본, 에스터 등의 매개유체(Carrier Fluids)에 혼합시켜서 콜로이드 상태로 사용하게 된다. 자성유체는 미세한 자기입자들이 매개유체내에서 서로 충돌하면서 반발력을 발생시켜서 상호간에 늘 콜로이드 상태를 유지하고 있으며, 이 특수유체가 자기장의 영향을 받게 되면 점도가 증가하면서 특이한 성질을 갖게 된다. 상대 접촉 운동면에 경계마찰이나 혼합마찰을 하게 되면 윤활상태는 비교적 나쁘다. 이러한 마찰지역에 콜로이드상의 자성유체 윤활제를 공급하면 기존의 윤활제에 비하여 대단히 효과적으로 윤활을 할 수 있게 된다. 그러나 자성유체 윤활제가 마찰부위에 원활하게 공급하기 위해서는 미끄럼 마찰부에서 자기장을 잘 형성시킬 수 있는 도체이어야 하기 때문에 특별한 윤활 시스템 설계가 제시되어야 한다. 자성유체 윤활제는 합성으로 제조된 특수물질로 여러가지 장점을 갖고는 있으나 기존 윤활유와의 적합성, 마찰열, 밀봉압력 등의 조건에서 제한적으로 사용될 수 밖에 없으므로 항공, 우주 산업이나 석유 화학분야와 같이 특수 환경에서만 사용되고, 또한 기존의 광유계 윤활제에 비하여 대단히 고가하는 문제점을 갖고 있다. 그러나 윤활 마찰면의 다양화와 가혹한 사용조건은 자성유체 윤활제의 연구개발 필요성을 크게 증대시키고 있다.xed Effects Model)을 결정하고, 각각에 해당하는 통계모형을 구축하였다. 이 결과 (1) 업종 및 기업규모별로 그룹간에 유의한 특성이 발견되었으며, (2) R&D 및 광고투자는 기업의 시장성과를 설명하는 중요한 변수이나, (3) R&D 투자의 경우는 광고에 비해 불확실성이 존재하는 것으로 나타났고, (4) 수리모형에서 도출된 한계원리가 통계모형에서도 유효한 것으로 드러났다.등을 토대로 한 10대 산업을 육성하기 위하여 과학기술부는 기술수요조사를 바탕으로 49개 주요기술을 도출하여, 과학기술 일류 국가 실현, 국민소득 2만불 달성이라는 국가적 슬로건을 내걸고 “차세대 성장동력” 창출을 위한 범정부차원의 기획과 연구비의 집중투자를 추진하고 있다.달성하기 위해서는 종합류류 전산망의 시급한 구축과 함께 화물차의 적재율을 높이고 공차율을 낮출 수 있는 운송체계의 수립이 필요한 것으로 판단된다. 그라나 이러한 화물전용차선의 효과는 단기적인 치유책일 수밖에 없기 때문에 물류유통 시설의 확충을 위한 사회간접자본의 구축을 서둘러 시행하여야 할 것이다.으로 처리한 Machine oil, Phenthoate EC 및 Trichlorfon WP는 비교적 약효가 낮았다.>$^{\circ}$E/$\leq$30$^{\circ}$NW 단열군이 연구지역 내에서 지하수 유동성이 가장 높은 단열군으로 추정된다. 이러한 사실은 3개 시추공을 대상으로 실시한 시추공 내 물리검층과 정압주입시험에서도 확인된다..

Biopolymer is a general concept for high molecular compounds produced by living organisms. Among them, the xanthan and β-glucan, which are organic polymer mixture produced by micro-organisms, are mainly used to increase the viscosity of a substance. And diluting in water and mixing with sand or clay can increase compressive strength and shear strength. In this study, mixed soil prepared by mixing soil with xanthan and beta-glucan based biopolymers specially developed for the purpose of increasing soil strength was applied to the river bank revetment, and changes during winter were measured using ground LiDAR. As a result of analyzing winter changes in major sections using three-dimensional point cloud data obtained through ground LiDAR, there were no changes to the extent that it was difficult to confirm with the naked eye in the two sections coated with biopolymer blended soil. However, soil loss due to Rill erosion was confirmed in the natural embankment section where biopolymer blended soil was not used.

웨어러블 컴퓨팅 환경에서 문자입력은 필수적인 태스크이나 적절한 유저 인터페이스를 지원하기란 쉽지 않다. 탁상용 QWERTY 키보드를 소형화하여 상용화한 제품도 있지만 일상에서 사용하기에는 상당히 부담스러운 크기이다. 본 연구는 단추와 유사한 크기로 부담 없이 의복에 부착할 수 있으며 적정 수준으로 문자입력 태스크를 지원할 수 있는 버튼 키보드를 제안한다. 버튼키보드는 기존 전화키패드의 $3{\times}3$ 키 배열을 단일 키 패드로 통합하였다. 이는 내구성 있고 간결한 폼팩터를 가능하게 하며 입력장치의 소형화와 문자입력효율의 향상을 가능하게 한다. 버튼키보드는 일반 키보드용 키에 터치센서와 LED 배열을 합성하여 구현하였다. 따라서 손가락의 위치에 따라 이격, 터치, 누름등의 상태를 구분할 수 있어 멀티탭핑방식에서 발생하는 입력분절문제를 해결하였으며 와이핑 모션에 의한 특수문자와 명령 입력을 가능하게 하였다. 프로토타입을 통해 문자입력수행도 테스트 결과 20세션 학습후 한손입력에 대해 평균 14.7WPM, 두손입력에 대해 평균 14.5WPM의 입력속도를 얻었다. 20세션 평균 에러율은 6%를 기록했으며 최고속도는 두손입력시 17WPM으로 나타났다. 실험결과를 통해 본 연구에서 제안한 버튼키보드가 기기를 극적으로 소형화하였음에도 불구하고 문자입력을 적정수준으로 수행할 수 있는 가능성을 가진 문자입력장치임을 확인할 수 있었다. 차후 프로토타입의 개선을 통하여 기기가 더욱 소형화될 수 있으며 문자입력수행도 또한 향상될 여지가 있다.

Special concentrically braced frames(SCBFs) have distinctive advantages in considerable seismic performance, which make engineers widely use SCBFs as lateral-load resisting systems in buildings and have researchers to develop SCBFs design methods. Compared to the extensive research of SCBF, comparatively little information is currently available on the performance of SCBFs designed and constructed before the early 1990's. Prior to 1988, concentrically braced frames(CBFs) design requirements were substantially less restrictive. As a result, many existing structures designed to these requirements may not ensure ductility and pose a significant concern in current buildings. In this study, these older frames are referred as non-seismic braced frames(NCBFs). In order to investigate the seismic behavior of NCBFs, finite-element(FE) models of SCBF and NCBF were suggested and verified using case investigation of NCBF conducted on the University of Washington. Using these models, the seismic behavior of NCBF with shared welding shear tab, which is the representative of the types of connections, was established and compared with the seismic performance of SCBF.

The aim of this study is to reveal errors in the estimations on the nonstandard workers scale which have resulted from little consideration for bogus self-employment. Bogus self-employment means disguised employment relationships that are considered to be self-employed workers even though they have inherent subordination. The methods of previous studies estimate that the bogus self-employed workers are excluded from estimations because they are not workers in principle. We analyze the scale of the bogus self-employments using the empirical data [the Korean Welfare Panel of 2008-2013(six wave panel)] to re-estimate the scale of non-standard workers. In 2013, the year of the last wave, the percentage of the bogus self-employment was high, the proportion of them is 28.5% among self-employment without owning a place of business. Our results expect the number of contract workers from re-analysis would be over 740 thousand when reflecting on the predictive value in the actual number of paid workers. In conclusion, it is necessary to apply reasonable methods of analysis concerning the scope and scale of the nonstandard workers for the sake of coping with measures against the problem of nonstandard workers. The aim of this study is to reveal the estimation error on nonstandard workers' scale which are resulted from having no consideration for bogus self-employment. Bogus self-employment means disguised employment relationship that is considered as self-employment workers even though they have inherent subordination. The methods of previous researches' estimation on nonstandard workers have the problem that the bogus self-employment workers are excluded from estimation because they are not workers in principle.

The purpose of this study was to understand the parents' perceptions of the distance learning provided to students with disabilities and to explore the demands for educational support. A survey was conducted on a total of 2,392 parents of school-age children with disabilities. The survey questions were largely divided into the learning support to prevent educational gap, support for behavioral and psychological difficulties, and care support for educational welfare. As a result of the study, it was found that face-to-face education in schools was the most important to prevent the educational gap between students with disabilities, and counseling on distance learning methods and strategies suitable for the characteristics of the disabled in connection with the Special Education Support Center was the most necessary. As a learning support method for distance learning for students with disabilities, there was a high demand for individual learning support through preparatory special education teachers, and it was necessary to secure enough learning aids and assistive technology devices to be used appropriately when needed. In addition, psychological counseling and educational support for students with disabilities were requested, and there were demands for development of care programs suitable for the characteristics of the disabled and assignment of dedicated personnel. Based on the results of this study, this study suggested implications for students with disabilities to bridge the learning gap and provide educational support due to distance learning.
