이진 영상을 위한 Compact Complementary Quadtree 의 구성

조영우(Cho Young Woo),김영모(Kim Young Mo) 한국정보처리학회 1997 정보처리학회논문지 Vol.4 No.1

In this paper, we propose a new preorder tree traversal method for binary images, named the Compact Complementary Quadtree (CCQ). In the proposed method we use type codes for representing nodes in the quadtree instead of using the symbols G, B, and W. From the experimental results, we have confirmed that the CCQ has a higher compressing ratio than of the DF-expression. CCQ can be effectively applied to progressive transmission of binary images such as line drawings, geographical maps, and halftones.

팔레트를 가지는 칼라 영상의 점진적 전송을 위한 새로운 피라미드 자료 구조

Palettized color images are the dominant type of the image used in Internet and World-Wide Web. In spite of this, most image compression and progressive transmission algorithm have been designed of continuous-tone images in such a aspect that pixel values are lookup table indices instead of physical intensity values. Hence palettized images have lower spatial correlation. In this papre, we propose a new pyramid structure for compression and progressive transmission of a palettized image. In the proposed pyramid structure, the color of a node at higher level is the one that occupies the most part in 4 sons and each node is represented by a type code and several color codes. Since the proposed method do not exploit spatial correlation in an image, it is ideally applied to lossless compression and progressive transmission of palettized images. We have confirmed this through the experimental results.

Objectives: The purpose of this study was to standardize the Korean version of the Reaction Inventory(K-RI) for measuring an individual's propensity for anger arousal. Methods: After translating the Reaction Inventory into the K-RI, the K-RI, Korean version of the Aggression Questionnaire(K-AQ), and Korean version of the Depression Anxiety Stress Scale-21(K-DASS-21) were administered to 424 Korean medical college students. The re-test was conducted with a 2-week interval of 119 students. Results: 1) The internal consistency of K-RI was 0.96(Cronbach's α, p<0.01). The test-retest reliability of K-RI was 0.68(Pearson's correlation coefficiency, p<0.01). Convergent validity was examined by Pearson's correlation coefficient between K-RI and K-AQ, which was 0.48 (p<0.001). 2) Four factors from K-RI were extracted by factor analysis with Varimax Rotation. The factors of K-RI were "Unpredictable disruptions and disturbances factor", "Embarrassing circumstances factor", "Personal disrespect factor", and "Unpleasant encounters factor". Conclusion: These results indicate that the Korean version of Reaction Inventory is a reliable and valid instrument to assess anger reaction.

초등학교 미술수업에서 랑시에르 미학의 의의

조영우(Young-Woo Cho),박동진(Dong-Jin Park) 한국국제미술교육학회 2021 미술과 교육 Vol.22 No.1

본 연구의 목적은 초등미술교육, 혹은 초등학교 미술수업에 랑시에르 미학이 주는 시사점을 찾는 것이다. 이를 위해 먼저 미적체제를 중심으로 랑시에르의 예술에 관한 논의를 통해 랑시에르 미학의 특징을 밝히고 일반적인 미술교육과의 연결점을 찾는다. 그리고 2015 개정 교육과정 「미술」의 초등학교 기초능력을 중심으로 초등학교 미술교육 및 미술수업과의 연관성을 살펴보는 방식을 취했다. 랑시에르 미학에 따르면 학생은 교실에서 평등한 일원으로 존재하며 스스로 감각을 만들어간다. 자유로운 놀이는 학생들의 언어를 해방시키고 의지를 발생시킨다. 감각이 해방된 학생들은 자유롭게 사유하며 수업의 중심이 된다. 그리고 자유로운 언어와 사고는 학생들에게 세상에 대한 이해의 폭을 넓히고 총체적 감각을 구성하게 하게 한다. 2015개정 미술과 교육과정의 초등학교 기초능력을 중심으로 살펴본 랑시에르 미학과 초등학교 미술교육 및 미술수업과의 연관성은 4가지로 정리된다. 첫 번째는 “자율성”으로, 수업에 흥미가 떨어지는 초등학교 5, 6학년 학생들의 의지를 유지시키고 표현의 위기를 넘길 수 있는 방법이다. 두 번째 “감각의 해방”은 미술수업에서 강요된 주제 해석과 표현에서 해방되는 것으로, 해방을 통해 학생들의 표현과정과 작품은 사회적 해석과 판단에서 자유로워진다. 세 번째 “문화향유와 융합교육”은, 동시대 미술문화 교육에 대한 것으로, 학생들은 흥미를 가지고 동시대 미술문화를 향유하며 생활 주변 미술문화를 다양한 분야와 융합하여 총체적으로 이해하고 구성한다. 마지막은 “자유로운 놀이와 의지의 생성”으로, 자유로운 놀이는 흥미를 유발하고 흥미는 힘든 탐색과 해석의 과정에서 의지를 유지시켜준다. The purpose of this study is to find the meaning and value of Ranciere’s aesthetics for elementary art education or elementary school art lessons. To this end, this study first determines the characteristics of Ranciere’s aesthetics through his discussions on art with a focus on the aesthetic regime and finds a connection to general art education. Moreover, we focused on the basic abilities for elementary school in the 2015 Revised National Curriculum of “arts” and examined their correlations with elementary school art education and art lessons. According to Ranciere’s aesthetics, students exist as equals in the classrooms and create their own senses. Free play emancipates students’ language and generates willingness to participate. Students with emancipated senses think freely and become the center of the class. In addition, free language and thoughts broaden their understanding of the world and help them form holistic senses. Ranciere’s aesthetics as examined with a focus on the basic abilities of elementary school in the 2015 Revised National Curriculum of Arts and their correlations with elementary school art education and art lessons can be summarized into four types. The first is “autonomy,” which can sustain the willingness of students in the 5<SUP>th</SUP> and 6<SUP>th</SUP> grade when they lack interest in class and overcome crises of expression. The second is the “emancipation of senses,” which refers to freedom from the forced interpretation and expression of the subjects in art lessons; through this, students’ process of expression and artwork can be unrestricted from social interpretation and judgment. The third is “cultural enjoyment and convergence education,” which is related to education on contemporary art and culture; through this, students enjoy contemporary art and culture with interest, combine art and culture in their surroundings with different fields, and understand and form such ideas on the whole. Finally, there is the “creation of free play and willingness” in which free play induces interest and interest maintains willingness in the difficult process of exploration and interpretation.

0.2% Ropivacaine을 이용한 성상신경절차단의 효과

조영우(Young Woo Cho),송선욱(Sun Ok Song),장주현(Ju Hyen Jang) 대한통증학회 2000 The Korean Journal of Pain Vol.13 No.2

N/A Background: Ropivacaine is a new amide local anesthetics, having therapeutic properties similar to those of bupivacaine but less cardiovascular toxicity and motor blockade. The aim of this study was to evaluate the effects of ropivacaine used in stellate ganglion block (SGB) compared with those of lidocaine or bupivacaine. Methods: This prospective and crossover study performed in twenty patients with sudden sensory neural hearing loss. All patients received three times SGB, in the paratracheal approach using 8 ml of 1% lidocaine, 0.2% bupivacaine, and 0.2% ropivacaine respectively without any orders. Onset time and action duration of Horner's syndrome were observed after each SGB. Results: Onset time of ropivacaine was the middle of the three agents; earlier lidocaine and slower bupivacaine. Lidocaine (3.0±1.9 min), bupivacaine (4.1±2.9 min) and ropivacaine (3.3±1.3 min). But there were no significant differences; Action duration of Horner's syndrome of ropivacaine (223.6±105.2 min) was longer than lidocaine (134.6±77.3 min) and shorter than bupivacaine (241.2±115.8 min). There were significant differences in the action duration of each local anesthetics (P<0.05). There was no critical side effects and temporary foreign body sensation was the most common side effect. Conclusions: We conclude that ropivacaine is a good alternative in SGB instead of lidocaine or bupivacaine. Ropivacaine is a long acting local anesthetic similar to those of bupivacaine with wide margin of safety. However, optimal concentration and volume of ropivacaine in SGB should be studied.

돌발성난청에서 성상신경절 차단 직후 순음청력치는 즉각적으로 변화되는가?

조영우(Young Woo Cho),송선욱(Sun Ok Song),권성현(Sung Hyun Kweon) 대한통증학회 2000 The Korean Journal of Pain Vol.13 No.2

N/A Background: Vascular occlusive event is one of the etiologies of sudden sensorineural hearing loss (SNHL). Stellate ganglion block (SGB) induces dramatic and intense vasodilatation in head and neck Based on this principle, SGB has used as one of the treatment modalities in SNHL. This study was performed to evaluate immediate response of SGB on pure tone audiogram (PTA) in SNHL. Methods: Forty patients were studied. Each patient received daily ipsilateral SGB in paratracheal approach using 0.2% bupivacaine for 2 weeks. On first, third, and fifth day of treatment, we checked their PTA twice 1 hour before (Pre-PTA) and after (Post-PTA) SGB. Pre- and Post-PTA were compared. Several factors were analyzed as a prognostic factor of therapeutic results. Results: Eleven of 40 patients revealed decreased PTA after SGB. Degree of decreased PTA were insignificant (2.5±1.6dB). Initial and final PTA results was 76.2±22.5 and 49.8±28.3dB, respectively. Thirty-one of 40 patients were improved their PTA over 10 dB. The recovery was mainly influenced by the severity of initial hearing loss (P<0.001) and slightly by age (P<0.05). However, the change of PTA after SGB, time interval to receive SGB, sex, site, and number of SGB were not correlated to therapeutic outcome. Conclusions: These results suggest that vasodilatation by SGB has no immediate improvement in SNHL. Therefore, we question whether SGB is beneficial to all patients with SNHL as a therapeutic modality.
