플라즈마에 레이저 빛을 입사한 후 CCD 소자로 획득한 영상은 검고 밝은 픽셀로 이루어지며 이를 플라즈마 스펙클 패턴이라 정의한다. 그림 1은 $NH_3$ 플라즈마에서 획득한 스펙클 패턴을 보이고 있다 [1]. 광학에서 스펙클 패턴은 빛의 산란을 이용해 정의하고 있지만 최근의 연구에서 이 같은 정의가 잘 못되어졌음이 보고된 바 있다 [2]. 스펙클 패턴은 입사된 빛 물질과 빛 물질 에너지를 흡수하는 표면 플라즈몬 캐리어 (surface plasmon carriers-SPC)가 함께 공존하는 전자계 에너지 필드라고 정의된 바 있다 [2]. 플라즈마 스펙클 패턴은 진공이 SPC와 같은 음의 물질과 입자로 채워져 있다는 가정에 기초하고 있다 [1]. 새로이 정의된 스펙클 패턴은 전하가 없는 photon 모델과는 달리 빛이 양의 전하를 가지고 있다는 사실에 기초한 것이며, 이는 최근의 빛 물질 수집과 관련한 실험적 연구 [3], 빛 물질의 화학적 원소 분석 [4], 빛 물질의 양의 입자성 [5]에 근거를 두고 있다. 빛 물질은 그림 2 [6] 에서와 같이 물 방울을 태양 또는 레이저 빛에 노출시켜 용이하게 수집할 수 있다 [3-6]. 플라즈마 스펙클 패턴에서 픽셀합 분포함수 (pixel sum distribution function-PSDF)을 구할 수 있으며, PSDF에서 추출한 정보는 optical emission spectroscopy, langmuir probe로 수집한 데이터와 매우 유사한 경향성을 보였다 [1, 6]. 이는 스펙클 패턴이 플라즈마의 광학적 전기적 정보를 저장하고 있음을 의미한다. 본 발표에서는 새로운 플라즈마 진단 방식으로서의 스펙클 이미징 시스템, 동작원리, 물리적 기초, 그리고 응용사례 등을 살펴본다.

As the main mathematical concepts are presented and expressed in various ways through textbooks during the teaching and learning process, it is necessary to look at the representations used in elementary math textbooks to find effective guidance. This study analyzed sentences used in the definition of mathematical terms and unit assessments of current elementary mathematics textbooks according to word depth (Yngve, 1960) from a syntactic perspective. As a result of the analysis, it could be seen that the sentences in textbook were generally concise, the word depth was lower, and the sentence structure and form were different depending on the individual characteristics of each term. Also, the sentences in the lower grade textbooks were more easily constructed, and the sentences of the term definition were more complex than the sentences of the unit assessments. Efforts should be made to help learners learn mathematical concepts, such as clarifying sentences in textbooks, presenting visual materials together, and providing additional explanations to suit the level of individual learners.

This study investigates the relationships of perfectionism and the affective traits(academic self-concept, learning attitude, interest, mathematical anxiety, learning habits) in mathematics between the gifted students and the regular students in Korean Middle Schools. The findings of this study can be used for the understanding of the gifted students, and as data or resources for counsellors when they advise the gifted students on enhancing study strategies and developing future courses. This study was investigated by measuring the relationships between perfectionism and the affective traits on mathematics between two groups. Here, the correlation analysis, t-test, and regression analysis of the SPSS for Window 12.0 Program were applied to measure the differences of both groups. Therefore, there were no differences in perfectionism between the gifted students and the regular students. But the self-oriented perfectionism of the gifted students appeared higher compare with regular students. The affective traits in mathematics of the gifted students appeared more positive compare with regular students. There were a few correlations between the perfectionism and the affective traits in mathematics at two group all. however the self-oriented perfectionism and the affective traits in mathematics showed to correlation. There were several suggestions based on the results of this study. First, the results showed that professional assistance is needed for the gifted students so that their perfectionism flows positively into developing their gifts. Secondly, the results suggested that specialized mathematical program reflecting on the affective traits of the gifted students in mathematics should be offered.Lastly, tthe results of this study suggested a researcher regarding relevance with perfectionism and affective traits regarding subject shall be performed more. The result of research shall be included to contents of training for the gifted students and their parents.

Copyright law has functioned to certify the authorship and artistic identity of an artist as well as to remunerate the artist's labor in monetary terms. However, the legal stability of copyright law may be questioned and even challenged because it shares the ground with unfixed notions of the concept of art. This study is an attempt to find theoretical argument where such instability of copyright law stems from, by looking into the theories of Aesthetics and history of arts. The first argument builds up on the ambiguity of discriminating between the Aesthetic concept of expression and idea. The second argument illuminates how new conventions of creating art work and emerging ideals of making art prevents to accommodate copyright law in the fields of art. New art forms such as conceptual art and place specific art are such examples. Increasing role of public arts projects also questions the conventional adoptions of copyright law. Arts management is closely related with this phenomena since their job is to administer the complex situation of introducing artists to the knowledge of copyright law.
