Objectives Alteration of epigenetic effects of testosterone during early development was suggested as an ancillary mechanism for the genesis of schizophrenia. EEG coherence was thought to be a marker for cerebral laterality of which important determinant was testosterone during early development. We studied sex-related differences of EEG coherences between patients with schizophrenia and controls to examine the sex effects in the genesis of schizophrenia. Methods EEG was recorded in 35 patients with schizophrenia and 46 healthy controls in the eyes closed resting state. Pair-wise EEG coherences were calculated over delta, theta, alpha, beta and gamma frequency bands. To examine the differences of EEG coherence according to sex in each group, ANCOVA was performed using Statistical Analysis system (SAS, Ver 9.3) and R (Ver 2.15.2). Results Healthy control males showed more increased right intrahemispheric coherences than healthy control females in delta, theta, alpha and beta frequency bands. In patients with schizophrenia, this male dominant pattern in right intrahemispheric coherences was attenuated especially in alpha and beta bands. Healthy control females showed more increased interhemispheric coherences than healthy control males in delta, theta, beta and gamma frequency bands. In patients with schizophrenia, these female dominant patterns in interhemispheric coherences were attenuated especially in delta, theta, and beta bands, which were commonly observed in frontal to central areas. Conclusion Sex differences in resting EEG coherences were attenuated in schizophrenia patients. These results imply that sex-related aberrant cerebral lateralization might exist in patients with schizophrenia, which are partly due to sex hormones via epigenetic mechanisms.

But even 6 years passed since the introduction, there are still faces manifold problems in the course of implementation. In order to examine the necessary improvements, in this study, I conducted interviews and questionnaires with experts, investigated the improvement items under current laws. And draw up a measures for that items. The subjects of the survey were fire-fighting officer, professional engineer fire fighting, fire protection planner and professor in Daegu. Interviews and Likert-type scale were conducted by taking the opinions of experts in each field.

리게티와 펜데레츠키의 음색 기보법 비교 연구

정혜민(Jeong, Hye Min) 청운대학교 방송예술연구소 2013 미디어와 공연예술연구 Vol.8 No.3

리게티와 펜레데츠키는 공통점이 많다. 둘 다 구 공산권 국가 출신이며 , 전후 작곡가 세대를 아방가르드적 작곡 양식을 통해 이끌었다고 할 수 있다. 그들의 미학적 경향은 음악적 재료 선택과 작곡 과정, 그리고 형식적 구성에 대한 태도 등에서 드러날 뿐만 아니라, 이를 종이 위에 기호화시킨 기보 방식에서도 읽을 수 있다. 작곡 경향과 기보 방식에 있어서의 차이점은 총렬음악과 우연음악에 대한 그들의 비판과 수용적 측면에서 살필 수 있다. 리게티는 작품의 전체를 일정한 법칙과 질서 안에서 엄격하게 통제하고 관리하는 총렬음악의 작곡 방식에 대하여 비판적으로 접근한다 . 반면, 작곡 원칙에 대하여는 일부분 수용하는 측면이 보이는데 , 그는 작곡과정뿐만 아니라 형식까지도 통제할 수 있는 작곡 방식으로 미크로폴리포니 를 제시한다. 이 기법을 통해 소리의 결과는 미세한 망형성체 로 구체화된다 . 펜데레츠키는 연주 시에 일어나는 의도하지 않은 우연성에 대한 고려를 작곡 과정에서 놓치지 않는다. 그의 그래픽 기보법은 바로 이러한 의도가 담긴 악보이다 . In the 20th century, Ligeti and Penderecki were the most representative composers of Tone-Color-Composition(Klangfarbenkomposition). Their concepts of the tone color depend on with Arnold Schoenberg. He has identified the Tone Color as a pitch and timbre dimension. For that, the tone color is not more adscititious, but first component of for sound. Ligeti and Penderecki, their modification of cluster aims to change the tone color. Based on their music we can understand that they have the same concept. This paper examined the influence of Serial Music on Ligeti, for all his criticism on it, and the influence of Aleatorik on Penderecki. I focused on their differences that can be recognized on scores. While Ligeti used traditional notation method, Penderecki has introduced a graphical notation. Ligeti was trying to manage the whole process of music performance strictly. In contrast to Ligeti, Penderecki considered for contingency that may arise in this process. Aside from that, he thought, the vision of a new tone material is important for visual shaping. And Penderecki s compositional concept was reflected strictly in his scores. His unique musical notation that has taken place is very important in the process of the development of modern musical notation will be able to tell.

해체주의 관점의 탈구성적 표현 특성

현대예술은 다양한 양식의 혼재 및 변화의 과정을 통해 새로운 패러다임을 형성하고 있으며, 디자인 분야에서도 열린 사고의 유연성을 반영한 탈구성적 표현이 새로운 디자인 발현 양식으로 나타나고 있다. 따라서 본 연구는 탈구성의 이론적 배경을 형성하고 있는 해체주의에 대해 고찰하고, 해체주의의 관점의 탈구성적 표현 특성을 해체주의의 대표 아티스트이자 디자이너인 론 아라드의 디자인 제품 사례를 통해 분석함으로써, 디자인 분야에 다양한 모티브와 영감을 제시하는데 목적이 있다. 연구결과는 다음과 같다. 탈구성의 개념에 대한 고찰을 통하여 ‘전형적인 구성의 부정’, ‘정형화된 형태의 거부’, ‘내부의 근본적인 해체’, ‘소재의 선입견 탈피’ 총 4가지의 유형으로 분류하여 표현 특성과 효과를 도출하였다. 론 아라드의 디자인 제품에 나타난 탈구성적 표현 특성은 다음과 같다. 첫째, ‘전형적인 구성의 부정’ 에서는 불완전한 기하학적 형태의 왜곡과 과장된 표현양상으로 정해진 원칙 없이 자유롭고 독창적인 효과를 가져왔다. 둘째, ‘정형화된 형태의 거부’ 에서는 기본 형태에서 벗어나 비대칭적, 방향성을 무시한 반복되는 패턴으로 형태의 왜곡을 표현하였다. 셋째, ‘내부의 근본적인 해체’ 에서는 붕괴된 질감이나 얽매이지 않은 혼합과 대비의 시각이 양면성을 이룸으로써 변형 및 변위된 개념을 제시하였다. 넷째, ‘소재의 선입견 탈피’ 에서는 서로 다른 이질적인 결합과 극단적인 대비 표현양상을 통해 소재의 경계를 허물고 소재의 선택에 있어 무한한 가능성을 보여주었다. 이와 같이 해체주의 관점의 탈구성적 표현특성과 효과는 기존의 개념이 가진 한정적 틀에서 벗어나 다양한 매체를 이용한 실험적 시도로 새로운 가능성을 열어 놓음으로써, 디자인 발상을 위한 자료를 제공하는데 의의가 있다. Contemporary art is forming a new paradigm through the process of mixture and change of various styles. In the field of design, the expression of decomposition which reflects the flexibility of open thoughts is appearing in the style of new design. Accordingly, this study would focus on deconstruction which forms the theoretical background of the decomposition and analyze the characteristics of decomposition which forms the deconstruction through the Ron Arad’s design products, thereby suggesting various motives and inspirations in the field of design. The result of the study is as follows: The research classified the concept of the decomposition into 4 types such as “negativity of the typical composition”, “rejection of the typified form”, “fundamental decomposition of the inside” and “escape from prejudice” and from them, the four characteristics and effect of expression were obtained. The characteristics of expression of decomposition from the view of Deconstruction focusing on the Ron Arad’s design products are as follows. First, the type of “negativity of the typical composition” leads to an incomplete geometrical distortion and overemphasized expression style, thus resulting in a free and creative effect without any specified principle. Second, the type of “rejection of the typified form” showed a pattern which is free from the basic forms, and which is asymmetrical and repetitive ignoring any direction, thus resulting in the distortion of the shape. Third, the “fundamental decomposition of the inside” showed duality through comparison with the collapsed texture or the non-bound mixture, thus suggesting the concept of modification and displacement. Fourth, the “escape from prejudice” showed the destruction of the boundary of materials and endless possibilities in the selection of the materials through the combination of mutually different foreign things and extremely comparative expressions. As such, the characteristics and effect of the decomposition expression from the view of deconstruction have the implications that they enable the design to get out of the limited framework of the conventional concept and then make experimental trials using various media, thus providing the data for the design idea.

Purpose:The purpose of this study was to find the ways to improve a quality of life of cancer patients through the family support by analyzing the correlation between quality of life and family support that cancer patients perceived. Methods: The questionnaires for this study were collected from 43 cancer patients who were admitted in general hospitals at Gyounggido from July 2004 to August 2004. The questionnaire was composed of total 60 items, which were general characteristics of 18 items, family support of 11 items and quality of life of 31 items. Kang's(1984) scale of family support and Tae's(2000) scale of quality of life were used. The data were analyzed with SPSS WIN 10.0 program using frequency, mean±SD, t-test, ANOVA and Pearson's correlation analysis. Results: Forty three cancer patients answered the questionnaire. Twenty three patients was a male and 20 a female. Mean scale of family support according to general characteristics was 3.87±0.71. Mean scale of quality of life according to general characteristics was 5.89±1.08 and relatively high. The better degree of education, the higher quality of life significantly and the less physical discomfort, the higher quality of life significantly. The quality of life when the patient burdens the spouse with treatment cost was significantly higher. A correlation between degree of family support and quality of life was r=0.488 and the higher family support that cancer patients perceived, the higher quality of life significantly(p<0.001). Conclusion: The higher family support that cancer patients perceived, the higer quality of life significantly. We suggest concrete and systemic program for family support.

Effects of chrysene on immune functions were studied in female BALB/c mice. When mice were treated po with chrysene for 7 consecutive days, the antibody response was suppressed dose-dependently. Chrysene induced the enzyme activities of CYP LA and 2B time- and dose-dependently. In ex vivo lymphocyte proliferation, chrysene inhibited splenocyte proliferation by LPS and Con A. Moreover, the numbers of $CD4^+IL-2^+$ cells were reduced by chrysene. In conclusion, chrysene-induced immunotoxicity might be mediated, at least in part, via IL-2 production, and caused by mechanisms associated with metabolic activation.
