ABSTRACT A Study on the Stroke of the Brush for the Expression of Nature and Its Changes LEE JI HO Advisor: Prof. JO SONG-SIG, Ph. D. Department of the Fine Arts Graduate School of Chosun University Many painters who study modern Oriental painting pursue a gradual change on the basis of the principle of the old thing-oriented creation of new things (法古創新) or attach great importance to the new conceptual meaning by borrowing the technique of Western painting or the function of media. The former depends on models for its technique of the brush, thought and subject materials, whereas the latter expresses the situations of the times by breaking away the existing viewpoints of thinking or traditional conception. Since the expression of nature was named as painting in the Orient, the changing process of painting has developed gradually. Therefore, painting has been always linked to traditions and modified its characteristics gradually, thus interacting with contemporary situations and prospecting the future from there. However, the expressive technique of the Orient which has been in line with the concept of harmony theory experiences somewhat confusion due to its mix with the ontological thought in the Occident. In other words, it is the phenomenon occurred in the process when the modern situations of painting come to face with the inherent rules of the Orient and the Occident and then contradict or assimilate with them. Therefore, the tendency of Oriental painting is classified into: The one which comprises all the traditional and modern viewpoints and then attempts to maintain balance between them; and the other which emphasizes creativity not from the aspect of tradition but from the aspect of new conception. This phenomenon seems to be derived from the combination of expressive materials or views of thinking with a variety of environmental factors. With this fact, we must perceive the necessity of being on the alert for the stagnant of the Oriental painting in the past or its cling to the phenomena of the times. In this vein, the investigator took the former's view and focused on the creation of modernity on the basis of old things in this study. In other words, by examining the meaning of traditional techniques of the brush, the investigator tried to draw out the new conception of all ages and countries. In addition, by reconsidering traditional thoughts and views of thinking from the modern aspect, the investigator pursued the change of expressive formation. This was mainly due to the investigator's formative formation, learned on the basis of tradition so far. However, it was also due to the requirement of the times which trying to change the tradition. In this vein, the investigator examined the answer by means of the two expressive formations in ancient and modern ages in general and then looked into the use technique of brush, ink stick and color. In addition, in the course of study, the investigator reconsidered the traditional expressive technique of landscape, which had been carried out customarily, and then introduced righteousness (spirit), rules (the technique of the brush), things (materials) and time (the nature of the times) into the investigator's new abstract technique of expression. Therefore, the investigator carried out an experiment based on a consistent category, namely the expression of nature, and then demonstrated its results. In the concertizing process of it, the investigator searched the answer from the model of traditional expression of landscape and then drew out diverse aspects. And based on study findings, the investigator began to change expressions and established new formative formations, namely rice paddies that depending solely on rainfall for water (天水畓) and wave patterns (波象紋). By breaking away the formation of actual or practical landscape in the past, the investigator drew out the linear formations of nature and then intensified its abstract formations in order to examine the inherent meaning of nature intensively. In particular, through the dynamics and harmony of lines, the investigator drew out musical, poetic and time-oriented meanings of nature and then tried to project the pure life of human beings who ultimately getting along with nature. Therefore, by going forward one step more from the original bearing of pursuing the technique of the brush and the change of expression, the investigator could approach a little near to the inherent attributes of nature expression, namely human beings and nature and nature and environment. In conclusion, in this study, the investigator drew out the viewpoint of traditional technique of the brush, the viewpoint of subject materials, the viewpoint of thoughts and ways of thinking and the viewpoint of nature and human beings and then brought them into the viewpoint of the times. In particular, they included internal and external meanings and phenomena, such as melodies, rhythms and dynamics simultaneously.

The purpose of this study is to examine the distribution of the eight core virtues of character education and the sub-components of each virtue in picture books for young children. The specific research questions selected for this are as follows. Research problem 1. What is the distribution of the eight core virtues of character education in picture books for young children? Research problem 2. What is the distribution of sub-components of eight core virtues of character education in picture books for young children? The subjects of this study are the top 10 books of monthly bestsellers since January 2016 among the top three children's picture books of 4 to 7 years old in the top three online bookstores in Korea according to the sales ranking record during the period from January 2016 to August 2019. Among the collected books, 91 picture books were selected for the final analysis, excluding duplicate books and books that did not contain stories. In order to analyze the distribution of character education virtues in picture books for young children, the analysis standard table of Lee Eun-jeong (2016) study was used focusing on the eight core virtues of character education, which were suggested by the Character Education Promotion Act (2015). The analysis was conducted from September 2nd to October 26th, 2019, and frequency analysis was performed by calculating frequency and percentage. The results of this study are summarized as follows. First, as a result of analyzing the distribution of the eight core virtues of personality education in the best-selling picture books of young children, 277 virtues were analyzed in the picture books of 91 children, followed by communication, consideration, respect, cooperation, responsibility, manners, filial duty, and honesty. The eight core virtues of character education are all dealt with in picture books of young children, but virtues are somewhat biased. Second, as a result of analyzing the distribution of sub-components by eight core virtues of character education in children's best-selling picture books, consideration among virtues was dealt with in picture books relatively evenly, but each sub-component of other virtues was concentrated in picture books. In conclusion, this study suggests that the virtues of character education for young children should be distributed evenly in picture books for young children in the future, focusing on the eight core virtues of character education in the Personality Education Promotion Act for the practice of proper character education in early childhood. 본 연구는 유아 그림책에 나타난 인성교육 8대 핵심 덕목과 각 덕목 별 하위 구성 요소의 분포를 알아보는 데 목적이 있다. 이를 위해 선정한 구체적인 연구 문제는 다음과 같다. 연구문제1. 유아 그림책에 나타난 인성교육 8대 핵심가치․덕목의 분포는 어떠한가? 연구문제2. 유아 그림책에 나타난 인성교육 8대 핵심가치․덕목별 하위구성요소의 분포는 어떠한가? 본 연구의 대상은 2016년 1월부터 2019년 8월까지의 기간 동안 매출 순위기록에 따른 국내 온라인 서점 상위 3곳의 4세~7세 유아 그림책 중 2016년 1월 이후 월간 베스트셀러 상위 10위 도서이다. 취합된 도서 중 중복된 도서, 이야기가 담기지 않은 도서 등을 제외하여 최종 분석 대상 그림책을 91권으로 선정하였다. 유아 그림책에 나타난 인성교육 덕목의 분포를 분석하기 위하여 인성교육진흥법(2015)에서 제시한 인성교육 8대 핵심가치․덕목인 예, 효, 정직, 책임, 배려, 소통 협력, 존중을 중심으로 이은정(2016) 연구의 분석 기준표를 사용하였다. 분석은 2019년 9월 2일부터 10월 26일까지 이루어졌으며 빈도와 백분율을 산출하여 빈도분석을 실행하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 유아 베스트셀러 그림책에 나타난 인성교육 8대 핵심 덕목의 분포를 분석한 결과 91권의 분석대상 유아 그림책에서는 총 277개의 덕목이 분석되었고 소통, 배려, 존중, 협동, 책임, 예, 효, 정직 순으로 덕목이 나타났다. 인성교육 8대 핵심 덕목이 유아 그림책에서 모두 다뤄지고 있으나 덕목들이 다소 편중되어 나타나고 있었다. 둘째, 유아 베스트셀러 그림책에 나타난 인성교육 8대 핵심 덕목별 하위구성요소의 분포를 분석한 결과 덕목 중 배려는 하위구성요소의 분포가 비교적 고르게 그림책에서 다루어지고 있었으나 그 외 덕목들의 각 하위구성요소는 그림책에서 편중되어 나타나고 있었다. 이러한 결과를 종합하여 본 연구는 유아기 올바른 인성교육의 실천을 위해 인성교육진흥법의 인성교육 8대 핵심 덕목을 중심으로 향후 유아인성교육의 덕목이 유아 그림책에 고르게 분포되어야 할 필요성이 있음을 시사한다.

Water cycle analysis is important in assessing the healthiness of water cycle by quantifying various elements of water cycle including evapotranspiration, infiltration, and runoff. Only after such assessment of water cycle is made, one can devise an improvement plan to address the problems identified. In this study, water cycle analysis was performed for Gunja drainage located in metropolitan Seoul using Aquacycle model developed in Australia to assess the problems of urban water cycle. In addition, feasibility analysis of reuse scenarios such as rainwater use and wastewater reuse was performed to examine their influences on improving the water cycle. From the analysis of water cycle of Gunja drainage, it was shown that hydrologic components such as evapotranspiration and surface runoff were highly dependent upon the change of impervious area. From the simulation of urban water cycle, it was found that, of total of 1,388 rainfall, 306 was lost through evapotranspiration. Surface runoff of 1,044 occurred, of which 937 at impervious area and 107 at pervious area. Finally, 99 of rainfall was recharged into groundwater. In summary, 75% of total rainfall occurred in the form of surface runoff, and groundwater recharge only accounted for about 7%. This suggests serious distortion of water cycle which can be attributed to urbanization. When compared to the water cycle in rural region (Pyungtaek in the vicinity of Seoul), it was found that impervious area of urban region was 9 times bigger, thereby reducing evapotranspiration by 39% and increasing surface runoff by 154%, and groundwater recharge has decreased by 75%. Along with water cycle analysis, the effect of rainwater use and wastewater reuse on water cycle was also evaluated using Aquacycle model for the study area. Reusable water was confined to use with irrigation and toilet water, and the analysis showed that the amount of reusable water was 890 combining rainwater and wastewater reuse. For the reuse, rainwater storage with a capacity of 20,000 was determined as optimal capacity in case of rainwater use and the wastewater treatment plant with a capacity of 2,700 in case of wastewater reuse. With rainwater use, it was shown that imported water supply of 312 can be saved through rainwater use, and that is water supply savings of 10% and surface runoff reduction of 26%. On the other hand, with wastewater reuse, it was shown that water supply savings of 31% and wastewater reduction of 30% can be achieved. There is not much rainfall except during summer season in Korea whereas the amount of wastewater occurs steadily in large volume throughout the year. For this reason, it can be said that wastewater reuse has an advantage over rainwater use in providing consistent water supply. The groundwater store level is getting low about 11cm per a year due to the forced pumping and groundwater use. Thereby river dry steam is on going. Also the groundwater recharge evaluated with SCS-CN was shown differences 4.2% of total rainfall according to soil classes in the study area. This study summarizes the application results of Aquacycle model as a tool for water cycle assessment and feasibility analysis of various reuse alternatives. With gloomy outlook on water supply for the future, the interest in alternative water resources such as rainwater and treated wastewater has increased substantially. As a science-based approach to shaping up of reuse options and comparing alternatives, Aquacycle looks to be a promising tool that can provide analytical muscle needed in both planning and implementation stage of water recycling program.

자동차 환경에 적합한 마이크로폰 어레이 시스템의 DSP 구현

이지호 연세대학교 대학원 2003 국내석사

전세계적으로 무선통신과 자동차의 통합 서비스인 텔레메틱스 개발이 활발하게 이루어지고 있다. 그리고 텔레메틱스용 음성인식을 위해서는 고품질의 음성 신호를 필요로 한다. 기존의 단일 핸즈프리 마이크를 이용한 음성인식 시스템의 경우 주위의 소음과 잔향으로 인해 그 성능의 제약을 받는다. 이러한 환경에서 음성신호의 향상을 위해 마이크로폰 어레이 기법이 연구되고 있다. 마이크로폰 어레이 기법에서는 일반적으로 광대역 MV(Minimum Variance) 빔형성기법이 많이 사용된다. 이 기법은 분해능이 좋고 간섭신호를 잘 제거하지만, 신호구간 내에서 공간 공분산행렬을 구하여 가중치를 계산하기 때문에 상관관계가 있는 간섭신호가 심한 환경에서는 음질의 향상을 보장할 수 없다. 반면 SINR(Signal to Interference plus Noise Ratio) 빔형성기법은 잡음구간에서 공간 공분산행렬을 구하기 때문에 잔향에 따른 음질의 저하를 막을 수 있다. 따라서 자동차용 마이크로폰 어레이 기법으로 잔향에 강인한 SINR 빔형성 기법을 사용하였다. 본 논문에서는 자동차내 음향 환경을 잔향과 잡음에 의한 영향을 분석하고, 마이크로폰 종류별, 어레이간 간격별로 실험을 거쳐 자동차용 마이크로폰 어레이 시스템을 최적화하였다. 여러 환경에서 실험해본 결과, 최상의 조건에서는 9dB 정도,평균 2-3dB 정도의 성능향상을 가져왔다. 마지막으로, 광대역 SINR 빔형성기법의 알고리즘을 16비트 고정소수점 DSP인 TMS320VC5416에서 구현할 수 있도록 고정소수점용 코드로 최적화하였다. Telematics, in-car wireless telecom services, have been developed in worldwide. Speech recognition system for telematics needs a clean speech signal. The speech recognition system using single-channel microphone has poor performance in noisy and reverberant environment. To improve the performance, microphone array techniques have been studied. In microphone array system, wideband MV (Minimum Variance) beamforming is generally used, since it has a good angular resolution and can reject interferences. This algorithm is degraded in reverberant correlated interference environment, since it uses the covariance matrix of the received signal (speech + noise). Therefore, the SINR (Signal to Interference plus Noise Ratio) beamformer is used to overcome the correlated interference problem. In this thesis, the effects of noise and reverberation are analyzed in automobile interior. Based on the analysis, a vehicular microphone array system was developed considering the array geometry and microphone types. The experimental results show that the proposed system achieved 9dB SNR improvement in the best condition, 2-3dB SNR improvement even in the worst condition. Moreover, the wideband SINR beamforming algorithm was implemented on TI TMS320VC5416.

지역적 워터쉐드 알고리즘을 이용한 동영상 객체 분할

李祉澔 全南大學校 大學院 2005 국내석사

최근 감시 카메라에서 실시간으로 객체 처리 기술이 한창 연구 중이다. 본 논문에서는 실시간 처리에 적합한 효율적인 자동, 반자동 동영상 객체 분할 알고리즘을 제시한다. 제안된 자동 동영상 객체 분할 알고리즘은 임계치 적용과 지역적 워터쉐드 알고리즘을 복합적으로 적용하였다. 또한 동영상의 형태에 따라 반자동 동영상 객체 분할 알고리듬도 제시하였다 첫 번째 자동객체 분할 방식은 입력영상에 임계치 분할방법을 사용하여 초기 객체 마스크를 구성하였고 반자동 객체 분할방식은 사용자와 컴퓨터 조력에 의한 분할방식을 사용하여 초기 객체 마스크를 구성하였다. 이러한 방식으로 구해진 초기객체 마스크는 현재영상에서의 영역분할을 위한 입력으로 들어가게 된다. 최종적으로 지역적인 워터쉐드 분할방법을 초기 객체영역의 불명확한 지역에서만 다시 수행하여 최종적인 객체영역을 획득하여 기존 방식에 비해 분할시간을 줄였으며 분할성능을 높였다. 본 논문에서는 잡음환경에서 객체를 추출하기위해 복합적인 분할방식에 초점을 두었다. 이러한 복합적인 분할방법을 사용함으로써 객체 마스크 추출성능의 향상과 수행시간절약을 가져올 수 있었다. In this paper, we propose an efficient moving object segmentation algorithm which is suitable for real-time applications. The proposed hybrid video automatic object segmentation algorithm combines threshold and local watershed techniques. additional semi-automatic object segmentation algorithm proposed as state of video. First, automatic segmentation processes that threshold segmentation technique is used to construct a initial mask image from frame difference information. Second, semi-automatic segmentation processes that user and computer assistance is used to construct a initial mask image. this initial segmentation is input to region-based current frame segment processes that produces the final segmentation. Finally, the local watershed segmentation is operated on the uncertain region of initial segment mask instead of whole image region, which can decrease processing time. In this paper, we focus object segmentation in noise environment by hybrid segmentation. This hybrid image segmentation algorithm can give accurate object masks with acceptable processing time.
