金公朱,김경수,전재홍,이화선 全北大學校 1995 論文集 Vol.40 No.-

In one bath dyeing system of silk/acrylonitrile(acryl) fabric with acid/disperse dyes and acid/cation dyes, adsorption behavior of acid dyes, disperse dyes and cation dyes on silk and acryl fabrics were examined. In the dyeing of acryl with the C. I. Disperse Red 19(Red 19) and The C. I. Disperse Red 60(Red 60), dye uptake with Red 19 was higher than that with Red 60. When the silk and acryl fabric were dyed with C. I. Basic Red 27(Red 27), dye uptake on the acryl was higher than that on the silk. When the silk/acryl fabric was dyed with Red 19 and Basic 27, solid shade could be obtained with Red 19 but could not be obtained with Basic 27. In the dyeing of silk/acryl fabric dyed with Blue 80/Red 27 and C. I. Acid Blue 113(Blue 113)/C. I. Basic Blue 116(Blue 116), compatibility could be obtained with Blue 80/Red 27 but that could not be obtained with Blue 113/Blue 116.

구성주의 접근에 기초한 인지이론이 유아교육에 주는 시사점

유연화,안경숙,김소향 경복대학 2001 京福論叢 Vol.5 No.-

최근 유아교육의 분야는 구성주의 접근에 기초한 인지이론의 영향을 받고 있는데, 이들은 Piaget 이론, 신-Piaget 이론과 Vygotsky이론이다. 구성주의 접근의 기초를 제공해주는 Piaget이론과 신-Piaget이론, Vygotsky 이론은 모두 인간의 사고과정 발달에 관심을 갖고 연구한 이론들로서 지식형성에 대한 유아의 능동적 역할을 강조한다. 본 고에서는 세 이론들을 고찰하고, 비교함으로써 구성주의적 접근법의 이해와 적용에 주는 시사점을 찾아보고, 유아교육과정과 교수학습방법의 이론적 방향의 기초를 마련하고자 하였다. The early childhood education are influenced by the constructivist perspectives. The constructivist perspectives on cognitive theory are Piaget theory, Post-Piagetian theory, Vygotsky theory. These theories were interested with development of thinking process and knowledge construction and stressed child's active roles. And also suggested important teaching-learning principle and curriculum in early childhood. We considered three theories, and then compared, made an offer the suggestion of these theories to early childhood education.

김성일,이성한,김명화,김기형,김상겸,유경석 고려대학교 스포츠과학연구소 1992 스포츠科學論叢 Vol.2 No.1

In general, the segment of human body moves(rotates) about its joint center by the elastic energy stored at the connecting element, such as, tendon, induced by muscle contraction. Various biomechanical methods have been conducted in the quest for finding the muscle contraction force and its moment at the joint, which can not be measured, directly. The muscle force and moment can be found utilizing inverse dynamics. In this study, the Lagrange energy method was employed applying kinetic and potential energy changes at the center of mass of the model segment during swing phase in normal gait pattern. A mathematical model needed to analyze this phase was developed, theoretically. The physical model was composed of the right shank and the right foot considering as a rigid body segment hinged at the knee joint. Two dimensional analysis using cinematography was used. The raw data was smoothed by the Butterworth digital filter(Winter, 1979). A computer program was developed in order to calculate forces at the joint by coding three Lagrange equations for each independent generalized coordinates. It was found that the smooth contact of the leading foot at the end of the swing phase was made for both subjects. The result confirmed that the Lagrange equation incoperation with the physical model be systematically sound for this kind of study. The extension of the study will be to include more segments into the physical model, so as to improve the proposed approach.

본 연구는 장애인의 자아존중감과 삶의 질의 관계를 고찰하며 주관적 건강상태와 차별경험의 매개효과를 검증한 것이다. 활용한 데이터는 한국장애인고용개발원에서 조사한 장애인고용패널 7차년도 자료이다. 분석대상은 7차년도 패널조사의 등록 장애인 4,082명이며, 그 중 임금근로 장애인 1,002 명을 대상으로 하였다. 분석방법은 기술통계분석과 위계적 회귀분석을 실시하였고 매개효과는 sobel test로 검증하였다. 분석결과 첫째, 자아존중감은 삶의 질에 정(+)적으로 영향을 미치는 것으로 나타났다. 둘째, 주관적 건강은 자아존중감과 삶의 질 간에 정(+)적으로 부분 매개함을 알 수 있었다. 셋째, 차별경험은 자아존중감과 삶의 질 간에 부(-)적으로 부분 매개하는 것으로 나타났다. 이와 같은 연구결과를 토대로, 임금근로 장애인을 대상으로 주관적 건강상태를 높이고, 차별경험을 줄일 수있는 정책적, 실천적 함의를 제시하였다. This study investigates how the self-esteem of wage workers with disability affects quality of life, focusing on the mediating effects of subjective health status and disability discrimination experience. The subjects of the analysis were 1,002 disabled wage workers in Korea from the 7th Disabled Employment Panel Data. The hierarchical linear regression model and Sobel test revealed that the self-esteem of wage workers with disability directly influenced on quality of life. In addition, the subjective health status of wage workers with disability positively and partially mediated the relationships between self-esteem and quality of life, while the disability discrimination experience of wage workers with disability negatively and partially mediated the relationships. Based on these results, this study makes suggestions for improving health-related status and reducing discrimination experience for the disabled.

<P>We report the synthesis of Mn<SUB><I>x</I></SUB>Ni<SUB>1-<I>x</I></SUB>O and Mn<SUB><I>y</I></SUB>Co<SUB>1-<I>y</I></SUB>O alloy nanoparticles by the thermal decomposition of the metal precursor in a surfactant. The different sized and shaped Mn<SUB><I>x</I></SUB>Ni<SUB>1<I>-x</I></SUB>O and Mn<SUB><I>y</I></SUB>Co<SUB>1<I>-y</I></SUB>O nanoparticles could be obtained by controlling precursors and surfactants. These alloy nanoparticles are antiferromagnetic and their stability is better than that of pure metal mono-oxides. On the basis of these results, we expect these alloy nanoparticles to have potential applications as electrodes in energy-generating devices such as Li-ion batteries. The higher Ni content (Mn<SUB>0.19</SUB>Ni<SUB>0.81</SUB>O) electrode exhibited a large reversible capacity (650 mAh g<SUP>–1</SUP>), a better initial efficiency (56%), and an improved rate and cycle performance, which was ascribed to higher electrical/electrolyte conductivity or improved surface film property. To our best knowledge, the reversible Li storage in metal oxides like MnO or NiO nanoparticles with about 10 nm diameter material itself has not been reported yet, indicative of the originality of the anode application of our materials. Also, we could expect a higher stability by addition of Mn into theconversion anode and reduction of material cost when compared with the very expensive Sn- or Mo-based oxide materials, electrolyte conductivity, or improved surface film property.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jpccck/2012/jpccck.2012.116.issue-45/jp301899f/production/images/medium/jp-2012-01899f_0010.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jp301899f'>ACS Electronic Supporting Info</A></P>

<P>We report on the direct and facile method for noble metal/graphene nano-composites from graphite without reducing agents. In this system, the irradiant white-light instead of the chemical reducing agent exerts the influence on the synthesis of noble metal nanoparticles on graphene. Noble metal salts adsorbed on graphene flakes which were functionalized with ionic surfactants were reduced by irradiation with white light. In particular, noble metal nanoparticles were more evenly distributed on the surface of graphene which was functionalized with SDS than with CTAB.</P> <P>Graphic Abstract</P><P>The direct and facile method for noble metal/graphene nano-composites from graphite without reducing agents was developed.

본 연구는 중고령 장애인의 자살생각 영향요인을 연구하고자 한다. 이를 위해 한국복지패널조사 7차(2012년)에서 11차(2016)의 패널데이터를 사용하였다. 중년(40세 이상 64세) 장애인 대상에서 경상소득, 가정생활스트레스가 자살생각에 유의하게 영향을 미치는 것으로 나타났고, 전기고령(65세 이상 74세) 장애인 대상에서 혼인상태, 경상소득, 우울, 가정생활스트레스, 가정생활만족도가 자살생각에 유의하게 영향을 미치는 것으로 나타났다. 후기고령(75세 이상)인 장애인 대상에서는 우울이 자살생각에 유의하게 영향을 미치는 것으로 나타났다. 이러한 연구 결과를 토대로 중고령장애인 자살생각 예방을 위한 정책적, 실천적 제언을 제시하였다. The purpose of this study is to explore and identify the factors influencing the suicidal ideation among middle-aged and elderly people with disabilities. For this, the study has used the panel data of the 7th (2012) through 11th sessions (2016) of the Korea Welfare Panel Survey. In the middle-aged (40 years old to 64 years old), it was found that ordinary income and family life stress significantly affected Suicidal ideation. In the elderly aged 65 to 74, the marital status, ordinary income, depression, family life stress, and satisfaction with family life significantly influenced Suicidal ideation. In the elderly aged 75 or older, depression was the decisive factor affecting Suicidal ideation This study has suggested an effective social welfare intervention plan to prevent the occurrence of suicide among middle-aged and elderly people with disabilities, which emerges as a serious social issue in Korea.
