Climate change and recent heat waves have drawn public attention toward other environmental issues, such as water pollution in the form of algal blooms, chemical leaks, and oil spills. Water pollution by the leakage of chemicals may severely affect human health as well as contaminate the air, water, and soil and cause discoloration or death of crops that come in contact with these chemicals. Chemicals that may spill into water streams are often colorless and water-soluble, which makes it difficult to determine whether the water is polluted using the naked eye. When a chemical spill occurs, it is usually detected through a simple contact detection device by installing sensors at locations where leakage is likely to occur. The drawback with the approach using contact detection sensors is that it relies heavily on the skill of field workers. Moreover, these sensors are installed at a limited number of locations, so spill detection is not possible in areas where they are not installed. Recently hyperspectral images have been used to identify land cover and vegetation and to determine water quality by analyzing the inherent spectral characteristics of these materials. While hyperspectral sensors can potentially be used to detect chemical substances, there is currently a lack of research on the detection of chemicals in water streams using hyperspectral sensors. Therefore, this study utilized remote sensing techniques and the latest sensor technology to overcome the limitations of contact detection technology in detecting the leakage of hazardous chemical into aquatic systems. In this study, we aimed to determine whether 18 types of hazardous chemicals could be individually classified using hyperspectral image. To this end, we obtained hyperspectral images of each chemical to establish a spectral library. We expect that future studies will expand the spectral library database for hazardous chemicals and that verification of its application in water streams will be conducted so that it can be applied to real-time monitoring to facilitate rapid detection and response when a chemical spill has occurred. 최근 기후변화와 여름철 고온 등으로 인한 녹조현상, 사고발생으로 인한 화학물질 및 유류 유출 등 수질오염과 관련된 사회적 관심이 높아지고 있다. 수질오염 사례 중 화학사고로 인한 유해화학물질 유출은 인체에 접촉시 인체에 악영향을 끼치며, 대기·수질·토양을 오염시키고 주변 농작물의 변색이나 괴사를 유발하는 등 생태환경에 직접적인 피해가 발생한다. 하천으로 유출가능성이 있는 화학물질은 무색의 수용성인 경우가 많아 육안으로 유출 사실을 확인하기가 어렵다. 화학사고 발생시 화학물질의 탐지는 간이접촉식탐지장비를 이용하거나 화학물질의 유출이 우려되는 곳에 검출센서를 설치해 사고를 감시하고 있다. 이러한 접촉식 센서는 현장인력에 의존적이고, 설치식 검출센서 또한 제한적으로 설치되어 미설치 지역에 대한 능동적 탐지가 어렵다는 한계가 있다. 한편 최근 초분광 영상을 활용하여 물질 고유의 분광특성을 분석함으로써 토지피복, 식생, 수질 등의 식별에 활용되고 있다. 따라서 초분광 센서를 활용한 화학물질 감지 가능성도 보여주고 있지만 연구는 미비한 실정이다. 본 연구에서는 수계로 유출되는 유해화학물질을 식별하기 위하여 접촉식 탐지 기술의 한계를 극복할 수 있는 원격탐사기법과 최신 센서기술을 활용하였다. 유해화학물질 18종을 대상으로 초분광 영상을 이용한 상호 구분이 가능한 지 확인하고자 해당 유해화학물질의 초분광 영상을 촬영하여 분광라이브러리를 구축하였다. 향후 연구를 통해 유해화학물질 분광라이브러리 데이터베이스를 확대하고, 하천 적용에 대한 검증을 실시한 후 실시간 모니터링에 적용할 경우 신속한 화학사고 발생여부 감지 및 대응에 활용할 수 있을 것으로 기대된다.

Vygotsky의 장애아 교육관에 관한 고찰

권영화 한국정신지체아교육학회 2002 지적장애연구 Vol.4 No.-

본 연구는 비고츠키의 장애아 교육관 고찰을 통하여 현대 특수교육이 나아가야 할 방향을 모색하는데 목적이 있다. 비고츠키는 생물학적 요인을 중시한 교육학을 전개하지 않았으나, 결코 생물학적 요인을 경시했던 것은 아니었다. 다만 장애아 교육이 지나치게 생물학주의적 방법론에만 의존하고, 교육학의 과제를 모호하게 하고 있는 점을 날카롭게 지적했던 것이다. 심신의 건전한 측면으로의 접근을 교육학의 과제라고 생각하고, 발달이라고 하는 관점에서 장애의 문제를 해명하려고 했던 비고츠키의 시도는 오늘날의 특수교육 방법론에서도 충분히 적용될 수 있는 것으로서, 앞으로 보다 심도있는 연구 분석이 요구되는 매우 가치있는 교육관이라고 할 수 있다. The purpose of this study was to research Vygotsky's view of education for the handicapped children. The conclusions drawn from this study were as follows. 1. Vygotsky regarded the secondary handicap that has resulted from a temperamental trouble as the main task in the education for the handicapped children. Accordingly, he emphasized such biological approaches as sensual training and curative education based upon the theory of developmental in order to solve children's handicap. 2. Vygotsky thought out the common feature of developmental principle of handicapped and nonhandicapped children from the conditioning theory of Pavlov. 3. Vygotsky regarded the social education that aimed at the combination with the life in society as the most important principle in development of the theory of education. He thought an interrelation between schools of handicapped and nonhandicapped children with their society as the major task, and ultimately he hoped to accomplish an ideal of integrated education with the nonhandicapped children. 4. Those ideas had the historically noticeable value as well as to be in accord with the mainstreaming of today.

거리두기 교수전략과 통제적 교수전략이 정신지체 유아의 혼잣말에 미치는 효과

권영화 한국정신지체아교육학회 1999 지적장애연구 Vol.1 No.-

본 연구의 목적은 5~7세 정신지체유아 30명과 그들의 어머니 20명을 대상으로 하여, 어머니들에게 거리두기 교수전략과 통제적 교수전략의 사용방법을 훈련하고, 어머니와 자녀가 함께 친숙한 모형가구-분류과제와 비친숙한 도형카드-분류과제를 수행하게 함으로써, 거리두기 교수전략과 통제적 교수 전략이 정신지체 유아의 혼잣말 발화 수와 혼잣말 수준에 미치는 효과를 알아보려는 것이다. 그 결과, 어머니의 거리두기 교수전략은 유아의 혼잣말을 조장하고 혼잣말 수준 향상을 촉진하였으나, 어머니의 통제적 교수전략은 유아의 혼잣말 발화를 방해하여 혼잣말 수준 향상을 억제한 것으로 나타났다. The purpose of this study is to investigate whether mother's distancing-teaching strategy and controlling-teaching strategy can catalyze private speech of the mentally retarded children, and to derive some implications for their private speech from this investigation. 30 children, aged 5 to 7, and 20 mothers were solicited from 2 day-care centers and 9 kindergartens in Taegu, Korea. In this experiment, 20 dyads, coupled with a mother and a child, were placed as the experimental groups and 10 children were placed as the control groups. According to the contents of strategy, 2 experimental groups, the distancing-teaching strategy group(GA) and the controlling-teaching strategy group(GB) were set. Participants in this study were asked to complete two tasks: a familiar task, and an unfamiliar task. Mothers of the Group A were trained to use distancing-teaching strategies such as the information-giving, verbalization of plans and activities, conceptual questions, and responsibility transference during the collaboration with children. Mothers of the Group B were trained to use controlling-teaching strategies such as commands, directives, direct corrections and perceptual questions during the collaboration with children. The Group C was the control group composed of children without their mothers' assistance, but they were administered the pre-post tests. The utterance and the level of private speech were examined three times: before the experiment; during the collaboration with mothers; and during independent task performance. In conclusion, mothers' distancing-teaching strategy motivated children's private speech and increased the level of private speech, while the mothers' controlling-teaching strategy interrupted private speech and decreased the level of private speech.

드론기반 시공간 초분광영상 및 RGB영상을 활용한 추적자 농도분석 기법 개발

권영화,김동수,유호준,한은진,권시윤,김영도 한국수자원학회 2022 한국수자원학회논문집 Vol.55 No.8

Due to river maintenance projects such as the creation of hydrophilic areas around rivers and the Four Rivers Project, the flow characteristics of rivers are continuously changing, and the risk of water quality accidents due to the inflow of various pollutants is increasing. In the event of a water quality accident, it is necessary to minimize the effect on the downstream side by predicting the concentration and arrival time of pollutants in consideration of the flow characteristics of the river. In order to track the behavior of these pollutants, it is necessary to calculate the diffusion coefficient and dispersion coefficient for each section of the river. Among them, the dispersion coefficient is used to analyze the diffusion range of soluble pollutants. Existing experimental research cases for tracking the behavior of pollutants require a lot of manpower and cost, and it is difficult to obtain spatially high-resolution data due to limited equipment operation. Recently, research on tracking contaminants using RGB drones has been conducted, but RGB images also have a limitation in that spectral information is limitedly collected. In this study, to supplement the limitations of existing studies, a hyperspectral sensor was mounted on a remote sensing platform using a drone to collect temporally and spatially higher-resolution data than conventional contact measurement. Using the collected spatio-temporal hyperspectral images, the tracer concentration was calculated and the transverse dispersion coefficient was derived. It is expected that by overcoming the limitations of the drone platform through future research and upgrading the dispersion coefficient calculation technology, it will be possible to detect various pollutants leaking into the water system, and to detect changes in various water quality items and river factors. 하천 주변 친수구역 조성, 4대강 사업 등과 같은 하천정비 사업으로 인해 하천의 흐름특성은 계속적으로 변동하고 있으며, 각종 오염물질 유입으로 인한 수질사고의 위험이 높아지고 있다. 수질사고 발생시 하천의 흐름특성을 고려해 오염물질의 농도 및 도달시간을 예측해 신속한 방제작업으로 하류로의 영향을 최소화해야한다. 이러한 오염물질의 거동을 추적하기 위해서는 하천의 구간별 확산계수, 분산계수 산정이 필요하며 그중 분산계수는 용존성 오염물질의 확산범위 해석에 사용된다. 오염물질의 거동을 추적하기 위한 기존 실험적 연구사례들은 많은 인력과 비용이 소요되고, 한정적인 장비의 운용으로 공간적으로 높은 해상도의 자료 취득이 어려웠다. 최근에는 RGB드론을 이용한 오염물질의 추적 연구가 수행되었지만, RGB영상 역시 분광정보를 한정적으로 수집한다는 한계가 있다. 본 연구에서는 기존 연구들의 한계점들을 보완하기 위해 드론을 활용한 원격탐사 플랫폼에 초분광센서를 탑재하여 기존 접촉식 측정보다 시간적, 공간적으로 고해상도의 자료를 수집하였다. 수집된 시공간(Spatio-temporal) 초분광영상을 활용해 추적자의 농도를 산정하고, 횡분산계수를 도출하였다. 향후 연구를 통해 드론 플랫폼의 한계를 극복하고, 분산계수 산정 기술을 고도화하면 수계로 유출되는 각종 오염물질의 감지 및 다양한 수질항목 및 하천인자의 변화량 감지가 가능할 것으로 기대된다.

도덕의 기원과 정당화에 대한 진화 심리학과 유학의 유사성에 대한 비판

권영화 한국동서철학회 2019 동서철학연구 Vol.0 No.94

This paper deals with the differences between Confucianism and evolutionary psychology. Evolutionary psychology resists of the existing moral such as metaphysical philosophy, based on rational and instruction but it claims the Altruism of biological basis and understands the moral’s fundamental contents with the biological facts. There are some preceding research analysis about Confucianism and evolutionary psychology for these have common in that based on the biological facts, Confucianism emphasizes the filial duty and kinship which are based on biological relationship. Therefore, in this paper, Confucianism also contains the scientific objectivity by comparing with evolutionary psychology. However, it is important not to regard the biological evolution is the ultimate virtue, following the survival of the fittest. Moreover, it is significant to recognize the empathy. It is clear that Mencius’s mind theory internalizes the conventional moral and relates both moral ethics and metaphysics phsychology. However, when we relate moral theory with biological basis, it is easy to consider more about the moral psychological aspect, overlooking psychological experiences through the Confucianism’s spiritual cultivation. As a result, it overlooks the meaning of Confucianism’s self-discipline and spiritual transcendence. Therefore, it is necessary to understand that both theories are based on moral and empathy but dealing with different dimensions during comparing the Confucianism and evolutionary psychology. 이 논문은 유학과 진화심리학의 차이에 대해서 논하고 있다. 진화심리학은 기존의 도덕 이성의 명령이나 신의 명령에 근거한 형이상학적 윤리학에 반대하며 이타성이라는 생물학적 사실에 근거해서 도덕의 기원과 내용을 설명하고 있다. 유가의 도덕도 생물학적인 혈연에 근거한 친족우선주의와 효 사상으로부터 출발하고 있다. 이런 공통분모 때문에 유학과 진화심리학의 연관성을 찾아보려는 선행연구들이 다수 존재한다. 유학과 진화 심리학의 대화를 통해서 유학이 이런 과학적 성과들을 흡수할 수 있게 됨으로서 과학적 객관성을 확보할 수 있다는 기대감을 갖게 된다. 그러나 생물학적 사실이 도덕적 가치로 넘어가는 것은 자연주의 오류를 범하는 것이다. 또한 생물학적 진화가 절대 선으로 간주될 경우 적자생존이라는 약육강식의 논리가 마치 도덕의 근본 전제인 것처럼 간주되게 될 것이다. 더 심각한 문제는 공감이라는 도덕 심리학과 도덕 형이상학의 구분점을 상실하는 것이다. 물론 맹자의 심성론에서 유학은 전통적인 덕을 심성의 범주로 환원되어 내면화시킨 부분이 존재한다. 이 때문에 선진 유학의 심성론은 도덕 형이상학과 도덕 심리학을 유기적으로 연관시키고 있다. 그러나 만일 진화심리학처럼 생물학적 사실에 입각해서 도덕 심리학적 내용만을 강조한다면 유학의 고유한 도덕 형이상학을 심리적 경험과 생물학적 사실로 치환하는 위험을 갖게 된다. 이는 유학의 심성론과 우주론과 수양론이 가지고 있는 내재적 초월의 의미를 상실하게 만드는 것이다. 따라서 진화 심리학과 유학을 비교 검토할 때 유학의 심성론과 수양론이 내포하고 있는 주요 목적과 내용을 면밀하게 검토하는 작업이 필요하다. 그리고 그 둘은 도덕 정감에 기초하고 있다는 사실에서는 유사하지만 도덕의 영역과 관련해서 전혀 다른 차원에 위치하고 있다는 사실을 깨닫는 것이 필요하다.

A Study was done in order to collect suggestion for the improvement of special education in Korea. Through a questionaire given to the teachers and administrators in special schools and special classes, opinions and suggestions were collected concerning establishment and management of special education facilities. The subjects of this study were 351 teachers and principals with special classes and 809 teachers in 53 special schools, the number of which is the complete enumeration of them all over the country. The information was complied from October 15, 1979 to December 20,1979. According to the analysis of the data collected in this study, the following suggestions were made for the improvement of the special education in Korea. 1. The existing state of the special schools. 1) At present, the number of children receiving special education is 14,159 persons(special schools;8,052 persons, special classes: 6,107 persons), bur it only represents 4.59 percent of the total number of children requiring special education in Korea. 2) The number of subjects that are presently being taught in special education schools, who have obtained special education teaching certificates, were shown to be 72% of the male teachers and 79% of the women teachers. 3) It was shown that home environment and parents' school career for children in the special schools were at the low level. 2. The teaching viewpoint of the teachers at the special schools 1) The special teachers' general point of view on the special schools was comparatively reached to the positive level. 2) There was generally such a tendency as they gave much more consideration to the life centered education than to recovering the academic achievement on the exceptional children. 3) The level of the general teachers' attitude to the special schools and the degree of the understanding was generally about at the middle. 4) In this research, it was shown that the teachers' motive to take the special schools was comporatively to be willing. 5) It was shown that the evaluation and treatment for the special teachers was at the low level of the satisfaction, and their works were too much. 6) The urgent problems in the education of the special schools was shown with the next order in the significant level; to strengthen the synthetic administrative supports, to develop and to supply the learning materials, to develop the curriculum for the special classes, and so forth. 3. The existing state of the special classes 1) At present, the number of children receiving special education in special classes is 6,107 persons. 2) The major problems with which the existing special classes are confronted, such as correct identification, reducing the number of pupils per special classes, putting in good order of the basic facilities at the special class etc. should be solved. 3) It is an urgent problem that a long-term comprehensive plan for the establishment of special classes should be set up, because their continuity and connection with each other fields have not been considered on the establishment of them. 4. The teaching viewpoint of the teacher at the special classes 1) The special teachers' general point of view on the special classes was comparatively reached to the positive level. 2) There was generally such a tendency as they gave equal consideration to receiveing the academic achivement, to the life-centered education and to the occupational education. 3) The present special classes were shown not to have the cooperative relationship with the regular classes. Also, the level of the general teachers' attitude to the special classes and the degree of the understanding was about at the middle, but it was shown that the regular children regarded the special classes as strange. 4) The teachers' motive to take the special classes was shown comparatively to be more willing than to be reluctant. 5) It was shown that the evaluation and treatment for the special teachers was at the middle level of the satisfaction, and their works were too much. 6) The urgent problems in the education of the special classes was shown with the next order in the significant level; to strengthen the synthetic administrative supports, to develop and to supply the learning materials, and so forth. 5. The teaching viewpoint of the principals at the special classes. 1) The major problem with which the existing special classes are confronted, such as correct identification, reducing the number of pupils per special classes, putting in good order of the basic facilities at the special classroom and developing a lot of special education materials etc. should be solved without delay. 2) A great consideration should be given to select a dutiful special teacher with teaching method techniques. 3) The teaching practice for the special education should be planned to convert the school subject centered program to the life and vocational education program.

權英花,金娜英 대구산업정보대학 1987 논문집 Vol.1 No.-

It is assumed that comprehending and remembering a story depeends not only on what the children hear or read, but also on their general knowledge. Some factors for children's story comprehension were considered under the following eading: 1) Mechanisms of understanding contained in story-comprehension, 2) The development of interesting of children for picture-books, 3) The role of repeating structure on the formation of "story schema", 4) The relation between levels of story-understanding and those of story-schema. From these consideration, the following suggestions were derived: 1) A large number of stories for children have some kind of repeating structure and children enjoy them very much, 2) Repeating structure play an important role on the formation of "story schema", 3) "story schema" is constructed in children's mind by their experience mainly about listening the story telling, 4) The developmental features of understanding depends upon the levels of children's schema or the degree of awareness for the goal or structure of task.
