The purpose of this study is to investigate the coloration characteristics by identifying the factor affecting red coloration of copper red glaze in traditional Korean ceramics. This study analyzed the characteristics of the reduction-fired copper red glaze by using XRD, Raman spectroscopy, EDX and UV-vis spectroscopy. As a result of XRD analysis, the glaze completely melted and amorphous glass appeared overall, and the characteristic peak of metal Cu was shown together. In addition, as a result of Raman analysis, the characteristic bands of CuO and $Cu_2O$ were shown together. The distribution of component elements was observed by EDX. As a result, copper(Cu) were distributed throughout the glaze. Thus, it was shown that copper red glaze appeared the best red coloration because metal Cu, CuO and $Cu_2O$ evenly existed throughout glaze in particle colloidal state. The chroma value of the copper red glaze was CIE $L^*$ 30.07, $a^*$ 13.65, $b^*$ 3.72. Wine-Red Solution was shown by Dark Graish Red coloration.

The Rutile – type brown pigments doped with chromium were synthesized. Samples of Ti_(1-x)Cr_xO_2 (0.02≤X≤0.08) were synthesized by the solid state method. Solid solution limit of Cr contents to the rutile structure and its coloration were studied. Optimum composition was investigated accordingly. The characteristics of synthesized pigments were analyzed by XRD, SEM, Raman spectroscopy and UV. As a result, single phase of Rutile was observed from 1000℃ by XRD. The maximum limit of solid solution was 0.06 mole Cr_2O_3. The glazed sample showed brown color, and the value of CIE L^*a^*b^* was L^* 33.27, a^* 10.64, b^* 20.84.

This study developed a pigment by doping Cr to Pyrochlore-type stannate crystals and investigated the chromogenic relationship in a glaze. Crystal phases of the pigment according to firing temperatures were analyzed by XRD, and the doping relationship was analyzed by Raman Spectroscopy. Color and reflection rate of the pigment were measured by UV-vis Spectrophotometer. Consequently, stannate characteristic band appeared at 307, 408, 505 and $755cm^{-1}$ until 0.1 mole substitution of $Cr_2O_3$. However, as amount of $Cr_2O_3$ increased, the stannate characteristic peak was decreased and shift happened at the left hand side due to Cr-dope. In composition of 0.12~0.14 mole substituted, the unreacted $Cr_2O_3$ stannate characteristic peak, which was not engaged, was shown. This result shows the maximum limit of solid solution was 0.1 mole $Cr_2O_3$. The color of the glaze, which was produced by adding 6 wt% of $Y_2Sn_{1.94}Cr_{0.06}O_7$ pigment in a lime or a lime-magnesia glaze and fired the mixture at $1260^{\circ}C$, was grayish pink with $L^*$ 70.29, $a^*$ 5.68 and $b^*$ 6.27. It showed gray with $L^*$ 68.82, $a^*$ 3.07and $b^*$ 8.13 for $Y_2Sn_{1.9}Cr_{0.1}O_7$.

This study investigatesthe coloration mechanism by identifying the factor that affects thered coloration of copper red glazesin traditional Korean ceramics. The characteristics of the reduction-fired copper red glaze's sections are analyzed using an optical microscope, Raman spectroscopy, scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDX). The sections observed using an optical microscope are divided into domains of surface, red-bubble, and red band. According to the Raman micro spectroscopy analysis results, the major characteristic peak is identified as silicate in all three domains, and the intensity of $Cu_2O$ increases toward the red band. In addition, it is confirmed that the most abundant CuO exists in the glaze bubbles. Moreover, CuO and $Cu_2O$ exist as fine particles in a dispersed state in the surface domain. Thus, Cu combined with oxygen is distributed evenly throughout the copper red glaze, and $Cu_2O$ is more concentrated toward the interface between body and glaze. It is also confirmed that CuO is concentrated around the bubbles. Therefore, it is concluded that the red coloration of the copper red glaze is revealed not only through metallic Cu but also through $Cu_2O$ and CuO.

레지오 에밀리아의 공간 접근법을 적용한 어린이놀이테마공간에 관한 연구

어혜진,김주연,백승경 한국공간디자인학회 2011 한국공간디자인학회논문집 Vol.6 No.2

어린이 놀이공간은 창의력 있는 인재육성과 여성의 사회진출이 활발해 짐에 따라 교육적인 가치를 띠는 전문적인 놀이공간으로 변화하고 있다. 본 연구는 사회성과 또래집단과의 교류, 교사와 관계에 주목하고 능동적인 어린이를 육성하는데 초점이 맞춰진 레지오 에밀리아의 공간 접근법을 고찰하여 유아학교에서 발견되는 요소를 중심으로 현대 어린이놀이공간을 분석하고 우리나라에 맞는 어린이놀이테마공간을 제안하는데 그 목적이 있다. 유아학교에서 추출한 공간적 특성은 개방성, 투명성, 자연성, 다양성, 조형성으로 구체화된다. 사례를 분석한 결과 우리나라 놀이공간에서는 개방성과 투명성이 부족하였고 캐릭터 위주의 놀이시설로만 꾸며져 있다. 레지오 에밀리아의 공간 접근법은 어린이공간을 어른의 축소공간으로 이해한다. 어른들의 세계인 도시구조를 반영한 어린이공간은 어른이 되기 위한 축소공간으로 도시와 사회와의 관계에 초점을 두고 있다. 레지오 에밀리아 이론을 근거로 어린이 공간을 보다 독립적인 공간으로 인정하고 관계에 초점을 맞춘 어린이 놀이공간으로 제시한다. With a trend of fostering creative human resources and as the women's social reputation and participation is increasing, the necessity of scholastic investigation of children's outing place is come to the fore. This research examined Reggio Emilia’s spatial approach to children’s sociality, exchanges among their peer groups, and relationship with a teacher, and focuses on development of children with active attitude. Through this, the research aimed to analyze modern children’s playgrounds based on the factors discovered in Reggio Emilia Nursery School and propose the theme play areas for kids to fit into the situation of Korea. From the nursery school, openness, transparency, and artistry were found as the spatial characteristics while sociality, equity, and naturalness were found as its human environmental factors. The results from analysis of the case revealed that the play areas in Korea lacked openness and transparency. The spatial approach of Reggio Emillia is focused on understanding of minimized space of adult society applying to children's outgoing place, in order to lead them experience the adult society what they are going to be in the future.

This study aims to investigate the effects of group art therapy running with course education to 4th elementary school student’s career consciousness maturity. The subjects of this study were 24 children from the Children's Learning Center, a clinic in the 4th grade student and they were attending elementary school 4th grade in Busan City Y-gu(The experimental group consisted of 12 students and the control group consisted of 12 students). The research tool was the Counseling From (B-1) adapted by Lee, Hyeonrim (1994), a career consciousness maturity test. The career education group art therapy program consists of 15 sessions from June 14, 2017 to August 11, 2017. The participants received a pre and post test. The data were analyzed by independent t-test to verify the homogeneity of the experimental and control group, and repeated measures analysis was performed to verify effectivenss. The results of this study are as follows; the sub-areas of career consciousness maturity, that is, career determination, career participation, career independence, career preparedness, career compromise, were appeared significantly different between the test periods and the groups. The results of this study suggest that parallel career education group art therapy has a positive effect on the career consciousness maturity of elementary school students. 본 연구는 진로교육 집단미술치료가 초등 4학년 아동의 진로의식성숙에 미치는 효과를 알아보는 데 목적이 있다. 본 연구의 대상은 부산시 Y구의 초등학교 4학년에 재학 중이며 센터에서 학습클리닉을 하는 아동 중 24명(실험집 단 12명, 통제집단 12명)의 아동을 선정하였다. 연구도구는 이현림(1994)이 번안한 Counseling From(B-1)인 진로의식성숙도검사이며, 진로교육 집단미술치료프로그램은 2017년 6월 14일부터 2017년 8월 11일까지 총 15 회기의 프로그램을 실시하였다. 자료분석은 실험집단과 통제집단의 동질성 검증을 위해 독립 t-test를 실시하였고, 효과성 검증을 위해 반복측정변량분석을 실시하였다. 본 연구의 결과는 다음과 같다. 진로의식 성숙도의 하위영역 인 진로결정성, 진로참여도, 진로독립도, 진로준비도, 진로타협도 모두 검사시기와 집단 간에도 유의미한 차이가 나타났으며, 직업에 대한 의미와 본인의 진로에 대한 인식변화 및 부모님에 대한 생각이 긍정적으로 변화되었다. 이상의 연구를 살펴본 결과 진로교육 집단미술치료가 초등학생의 진로의식성숙에 긍정적 영향을 미치고 있음을 알 수 있었다.
