Silver/poly(methyl methacrylate) (PMMA) nanocomposites were synthesized in situ by thermally heating a solution of a silver n-propylcarbamate (Ag-PCB) complex and PMMA/MMA (1/9) in the presence of a radical initiator. Polymerization of the MMA monomers and reduction of the silver ions occurred simultaneously, leading to the formation of Ag/PMMA nanocomposites. The resulting Ag/PMMA nanocomposites were characterized by infrared spectroscopy (IR), X-ray powder diffraction (XRD) and high-resolution transmission electron microscopy (TEM). TEM showed that the silver nanoparticles with diameters ranging from 5 to 30 nm were well dispersed in the PMMA matrix. Brownish transparent chips of the Ag/PMMA (0.1/99.9) nanocomposites with a particle size and distribution comparable to those of the Ag/PMMA nanocomposites were obtained by in situ reduction and radical polymerization using the silver nanocomposites with the composition, Ag/PMMA (4/96), as a master batch.

본 연구는 최근 3년간 국립재활원 장애인 운전재활 프로그램에서 수집된 자료를 이용하여 실태를 조사하는 것이다. 국립재활원에서 운영하는 운전재활 프로그램은 운전체험과 운전교육 프로그램이 있으며, 2019 년부터 2021년까지 운전체험 프로그램에 참여한 621명, 운전교육 프로그램에 참여한 1.042명으로 수집된자료를 분석하였으며, 대상자의 일반적 특성, 장애관련 특성, 운전관련 특성을 파악하기 위해 기술통계를실시하였다. 또한, 운전체험과 운전교육 프로그램 현황을 파악하기 위해 빈도분석을 실시하였다. 연구결과, 운전재활프로그램 대상자는 주로 경제활동과 여가활동을 위해 운전재활 프로그램에 참여하고자 하였다. 교육을 받은 대부분의 대상자는 지체장애인과 뇌병변장애인이었고, 주로 서울과 경인지역에 편중되어있었다. 또한, 운전체험 프로그램 참여자 중 운전교육이 필요한 경우가 42.5%였고, 운전교육 대상자의64.9%는 운전면허 소지자였다. 연구결과를 통해 전국 각 지역의 운전재활 프로그램에 대한 접근성을높일 필요가 있으며, 국립재활원과 각 지역 장애인운전지원센터, 운전면허시험장의 역할과 특성화된 교육프로그램이 마련될 필요가 있음을 확인하였다. 또한, 추후 지속적인 운전재활 프로그램의 개선을 위해디지털 기반의 안정적 데이터베이스를 구축할 필요가 있다. The purpose of this study is to investigate the actual situation using data collected from the National Rehabilitation Center's driving rehabilitation program for the disabled over the past three years. We analyzed the collected data of 621 people who participated in the driving rehabilitation experience program and 1,042 people who participated in the driving rehabilitation education program from 2019 to 2021, and conducted descriptive statistics to investigate the characteristics of the subjects and driving rehabilitation program. The paired t-test were conducted to compare changes before and after driving rehabilitation education program and the required time for driving training. According to results of this study, the most of subjects selected driving rehabilitation program to participate in economic and leisure activities, with physical disabilities and brain lesions. 42.5% of driving rehabilitation experience subjects, needed driving training. 64.9% of driving rehabilitation education subjects were driver's license holders, and as a result of comparing before and after driving training, there was a significant change in all driving ability, and driving training required time decreased significantly from 9.96 hours to 3.52 hours. In order to increase accessibility to driving rehabilitation programs, it is necessary to establish the role of the National Rehabilitation Center, driving support centers for the disabled in each region, and specialized training programs. Also, it is necessary to establish a digital-based stable database to improve continuous driving rehabilitation programs.
한국의 복지제도 발전과정에 관한 역사적 고찰 : 식민 통치 시대를 중심으로 a points term colonial Government
홍완표,박공명 안성산업대학교 1999 論文集 Vol.31 No.-
This study is historical point as Welfare institution, until transition from 1910 to 1945, rule government time, of the Korean Welfare Development process. The purpose of this study are as follow, the first one is to find which theory is the seven development hypotheses about welfare system, second is to find, for building, the Korean Welfare policy and reviewing what suggestion it makes to the future institution. ChapterⅢ is welfare institution growth and its incentive are examined, the historical transition of the welfare institution on the United Kingdom and United States. So as ChapterⅣ is general survey welfare institution of the Japanese colonial policy and its influence. ChapterⅤ is analysis from the Korean welfare transition of the colonial government in term, as a result, of the historical change the Korean welfare policy, its shown that the development theory of public welfare system, which aim to control society based on conspiracy theory, is more convincing. Also, The Korean welfare institution is transplanted, because of the Japanese welfare policy and its system is very draw aza distinction between colonial government people and Japanese. When, the welfare consider laws and institution are legislated and operated for the sake of political convenience and political goals, various laws in very disorderly manner and there many authorities concerned. In many case, the welfare laws and regulations are there only for display, producing no actual. In the future, th Korean welfare policy shall be put in a synthetic institution.
메타크릴레이트계 4차 암모늄 유도체 고분자 전해질의 감습특

고분자 전해질의 화학구조가 감습특성에 미치는 효과를 조사하기 위하여 $C_{1}\sim C_{12}$의 알킬,benzy1, 2,2-diethoxy dthy1기가 치환된 메타크릴계 4차 암모늄 단량체들을 합성하였다. 이들의 감습용액을 0.15mm간격의 빗살 모양의 금전극이 인쇄된 알루미나 기판에 마이크로 주사기로 도포하여 광중합 후 상대습도에 따른 임피던스 변화를 측정하였다. 도포된 막의 두께가 증가하면 임피던스는 감소하고, 치환기의 탄소 길이가 증가할수록 임피던스는 증가하였다. $C_6\sim C_8$의 알킬기를 가지는 고분자 전해질의 감습특성은 30-90% RH 범위에서 18M$\Omega$-5K$\Omega$의 직선적인 임피던스 변화를 보였다. 또한 임피던스는 온도 의존성을 보여주며 온도가 증가하면 임피던스가 감소하며 온도 의존성 계수는 -0,45% $RH/^{\circ}C$이다. 히스테리시스는 $\pm$2%RH이내이며, 33%-85% RH 사이에서의 응답 속도는 약 35sec이었다. Methacryloxyethyl dimethyl alkyl($C_{1}\sim C_{12}$, benzyl and 2, 2-diethoxy ethyl) ammonium bromide monomers were prepared to investigate the relative humidity characteristics for polymer electrolytes with different chemical structures. They were coated on the alumna substrate printed comblike gold electrode by photopolymerization after micro-syringe injection. As the thickness of rhe humid membrane increased, the impendance decreased, whereas the impedance ~ncreased as the carbon cham of alkyl substituent in the monomer increased. The impendance of the polymeric electrolytes with $C_6\sim C_8$ substituents were varied from 19M$\Omega$ to 5K$\Omega$ for the range of 30-90% Mi. The temperature depedence coefficient in the range of 15-$35^{\circ}C$ was found to be -0.45% $RH/^{\circ}C$and the hysteresis falled within the range of $\pm$2% RH. The response time was 35 second for varying humldity from 33% to 85% RH.
