In this paper, we proposed an analytical model for TFT which has series of the polycrystalline structures. An average speed is defined as carrier speed by the electric field. The effective square is suggested as the area of grain without depletion for the changed grain size. First, physical parameters such as grain size, channel lenght and trap density, have been changed to prove the validity of the average speed model and the value of the effective square has been estimated through drain-source current.

The present study developed teaching-learning activities to improve personal intelligences and to investigate their effectiveness. Significant differences were found in both interpersonal and intrapersonal intelligence. Positive effects appeared in cooperative attitudes, capacity to care for and understand others, and in reflective thinking abilities. The results suggest the importance of a balanced educational curriculum in order to enhance human affective aspects, self-esteem, cooperative classroom climate formation and the moral and character development of students. Consistent and systematic investigation is needed on multiple intelligences theory, development of teaching-learning activities, their longitudinal effects, and a fair assessment instrument.

PV module is manufactured by several steps such as cell sort, tabbing & string, lay-up, lamination processes. In oder to manufacture PV module, solar cell must be placed in high temperature. Soldering Process in high temperature is important because it directly influences electric output performance changes of solar cell in solar cell module. We consider applying momentary high temperature, while soldering solar cell, and expect change electric characteristics of PV module. In this paper, we measure electric output characteristics of solar cells after those are applied with high temperature changes for two seconds. From these results, we confirm with application of high temperature, I_{sc} increase and V_{oc} slightly decreases.

이 연구는 다중지능을 활용하여 중학교 국어과 문학 수업을 개발하고, 그에 따른 수업의 효과를 분석하였다. 이 연구에 참여한 학생들은 경기도 소재 중학교 1학년 학생들로 수업은 총 9차시로 개발되었다. 모둠은 다중지능 영역 중 강점 지능 영역이 같은 학생들로 구성되었다. 학생들의 다중지능을 파악하기 위해 MIDAS 도구가 활용되었고, 국어에 대한 학생들의 의식 및 태도를 알고자 서술형 설문조사를 하였다. 문학수업에 대한 학생들의 내면적인 지각과 이해를 알기 위해 심층면접을 실시하였다. 연구결과 학생들은 첫째, 국어 수업에 대한 인식에서 긍정적인 변화를 가져왔고, 둘째, 문학 감상 능력이 신장되었으며, 셋째, 자신의 강점과 약점 지능에 대한 이해가 증진되었고, 그리고 넷째, 서로를 통한 배움을 통해 대인관계 능력이 향상되었다. 이 연구는 중등교육에서 일반적으로 받아들여지는 언어 치중적 강의법만이 아닌 학습자의 다양한 강점 지능 영역을 고려한 다양한 교수법 개발과 실천이 요구되고 있음을 보여준다. The purpose of this study was to examine whether there is any effect of multiple-intelligences-based (henceforth, MI-based) Literary instruction in middle school. The first grade students(one class) in Gyeonggi-Do province participated in this study. Shearer's Multiple Intelligences Development Assessment Scale(MIDAS) were used to investigate students' strength intelligence. Descriptive survey was needed to find student's attitude about language and literary instruction. In-depths interview was used to analyze the effects of the MI-based Literary instruction. The findings of the study were as follows ; First, the positive attitude change about Language subject were appeared. Students eagerly participated in class activity. Second, the appreciative ability of Literature was developed. Third, to know one's strength and weakness seems to help the students to understand themselves. Fourth, using students' cooperative team strength-intelligence-based improved their interpersonal ability. The results of this study show that the efforts to develop and practice learner's strength-intelligence-based teaching and learning methods on various subjects in middle school education were needed.
한국(韓國)의 문화(文化) : 구봉 송익필의 서예연구 -『삼현수간』을 중심으로-
정태희 ( Taehee Jung ) 한국사상문화학회 2016 韓國思想과 文化 Vol.81 No.-
구봉 송익필은 16세기 조선유학자로서 당시 시의 삼걸(三傑)이며 8문장 가이자, 조선최초 4례서인 『가례주설』을 저술한 예학자이다. 『삼현수간』은 성혼과 이이 등과 나눈 편지글로서, 구봉을 비롯한 이이의 친필자료들이 담겨져 있어서 서예사적인 면에서도 중요한 자료가 되어 오늘날 보물 1415호로 지정 되었다.송익필은 초서에 뛰어나서 후대의 초서풍에 영향을 주었음에도 그의서예에 관한 학계의 기존연구는 찾아보기 드물어 본 연구가 처음이라고 사려 된다. 본 연구에서는 그의 글씨의 연원과 서풍을 『삼현수간』을 통해 구명하고자 하였다. 송익필은 성리학적 이상을 구현하고자 했던 도학자로서, 시종일관 왕희지체를 보이면서도 더욱 웅건하면서 골기가 강한 필세의 초서를 쓰고 있으며, “지극히 정밀한” 해서법의 기초 위에서 세워졌다고 사려 된다. 『삼현수간』을 통해 본 송익필의 글씨는 엄정웅일한 결구의특징을 지녔고, 담박순일한 정취를 지녔으며, 또한 농묵초서(濃墨草書)로귀결된다고 할 수 있다. 특히 시작(詩作)과 합치된 ‘시서일치(詩書一致)’는독자적 서풍을 이루어 낸 서예가로서 자리 매김하게 한다. 송익필의 서예관은 글씨는 마음의 표현이기 때문에 글씨를 씀에 있어 예학의 자세로 일관하였음을 알 수 있다. 이상으로 볼 때, 송익필의 글씨는 왕법(王法)과 예학(禮學)과 심법(心法)의 도학자적 사유방식과 행위규범으로 재해석하여 만들어낸 독자적인 산물이며, 당시나 후대 사람들에게 도학자 글씨의 전형으로 학습되면서 시대서풍을 주도해 가는데 결정적인 역할을 하였다고 하겠다. 아울러 송익필 초서풍의 글씨는 후학들에게 ‘학서(學書)’의 규범으로서 큰 역할을 하여, 17세기 기호예학파의 글씨 전형으로 자리 매김 되었음에서 그 서예학술사적 의의를 찾을 수 있다고 하겠다. Gubong Song Ik-pil is a confucianist in Chosun dynasty in the 16th century. He was one of the three important figures in poetry and eight writers of the period. He is represented by Garyejuseol which is a four formality for the first time in Chosun. Three Wise Men``s Letters(三賢手簡) is a collection of letters between Yi Yi and Seong Hon. It is a significant handwritten material with the meaningful statue in calligraphy history. It is designated as Korea’s treasure number 1415.Song Ik-pil was excellent in cursive writing. Even though he influenced on the later cursive writing style, previous academic researches on his calligraphy have not done enough. This paper takes an in-depth study on the origin of his handwriting and his writing style presented in Samhyunsugan. Song Ik-pil was a neo-confucianist who tried to realize the ideal neo-confucianism. He persisted with cursive script which was vigorous and strong.This paper suggests that his cursive script was founded on the basis of Haeseo which was extremely precise. His writing presented through Samhyunsugan is bold but simple. His philosophy in calligraphy was about expressions of hearts and he kept his attitude for politeness study.His writing has a significant role in leading the writing style which was acquired by people those days and later time as a model writing style of neo-confucianists. His cursive writing style plays a key role as a norm for academy and calligraphy for later scholars. His style established its statue as a model writing for Kiho politeness study which succeeded his academic line until 17th century with a significance in calligraphy history.

It is well-known that Boron-doped Cz Si solar cells suffer light-induced degradation due to aboron-oxygen defect which is responsible of a reduction in lifetime and hence efficiency. In this paper, we assume that PV solar cell has been connected with variable load to account the real operating condition and it shows different light-induced degradation of Si solar cell. To evaluate the effect of light-induced degradation for solar cell with various load, Single crystalline solar cells are connected with open and short circuits during light exposure. Isc-Voc curve evaluate light induced degradation of solar cells and the reason is explained as a change for serial resistance. From the results, Electrical characteristics of solar cells show better performance under short circuit conditions, after light exposure.
