조경원(Kyung won Cho),백란(Ran Baik) 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.12

우리나라 넙치 양식은 수산 양식 산업의 절반 이상 차지할 정도로 큰 비중을 차지한다. 그러나 넙치 연중 총사육량의 25-30% 정도가 질병으로 인한 집단 폐사가 발생하여 양식장의 경제성에 매우 나쁜 영향을 준다. 넙치 양식장의 경제성 성장을 위해서는 넙치 질병 증상 진단을 자동화하여 실시간으로 정확하게 질병을 진단하는 방법이 필요하다. 본 논문에서는 딥러닝 기반 넙치 질병 증상 분류 모델에 적합한 독자적인 학습 데이터 수집 방법, 라벨링된 학습 데이터 셋 오류를 없앨 수 있는 학습 데이터 정제 및 검증 기법, 균등한 학습 데이터 분리 기법을 제안하고, 제안된 기법을 적용하여 총 4,946개의 어노테이션 이미지를 대상으로 넙치 질병 증상 33개 카테고리에 대한 넙치 질병 분류 성능을 CNN 기반의 YOLOv8 모델과 비전 트랜스포머 기반의 Swin모델을 이용하여 학습한 결과를 비교 분석한다. YOLOv8 모델은 100 Epoch까지 학습을 진행하여 mAP 인식률은 0.899, 학습 시간은 10 Epoch당 3분, VRAM 사용량은 15.4GB의 성능을 보여주었다. Swin 모델은 50 Epoch까지 학습을 진행하여 mAP는 0.91, 학습 시간은 10 Epoch당 162분, VRAM 사용량은 21.3GB로 나타났다. YOLOv8 모델과 Swin 모델의 성능을 비교하면, Swin 모델은 더 적은 Epoch로도 좋은 mAP 성능 인식률을 보여주었으나, 학습 속도면에서는 YOLOv8 모델이 압도적으로 짧은 학습시간으로 학습을 완료하였다. 본 연구 결과와 같이 최신 딥러닝 모델을 이용하여 넙치 질병 증상을 실시간으로 진단할 수 있는 시스템이 개발되면 유수식 넙치 양식의 생산성은 크게 증가될 것이라 기대된다. Halibut farming in Korea accounts for more than half of the fishery farming industry. However, 25 to 30 percent of halibut fish deaths are caused by disease per year, which has a very bad effect on the economic feasibility of halibut farming. The accurate diagnosis of halibut disease symptoms in real time is very important for the economic growth of halibut fish farms. In this paper, we propose an independent learning data collection method suitable for a deep learning-based halibut disease symptom classification model, a learning data purification and verification technique that can eliminate labeled learning data set errors, and an equal learning data separation technique, and apply the proposed technique to compare and analyze the halibut disease classification performance for 33 categories of halibut disease symptoms using CNN-based YOLov8 model and Vision Transformer-based Swin model. The YOLOv8 model learned up to 100 Epoch, showing a performance of 0.899 mAP recognition rate, 3 minutes of learning time per 10 Epoch, and 15.4 GB of VRAM usage. The Swin model learned up to 50 Epoch, and the mAP was 0.91, the learning time was 162 minutes per 10 Epoch, and the VRAM usage was 21.3GB. When comparing the performance of the YOLOv8 model and the Swin model, the Swin model showed a good mAP performance recognition rate with less Epoch, but in terms of learning speed, the YOLOv8 model completed the learning with an overwhelmingly short learning time. As shown in the results of this study, if a system that can diagnose halibut disease symptoms in real time using the latest deep learning model is developed, the productivity of the floating halibut style is expected to increase significantly.

유교 女訓書의 교육원리에 관한 철학적 분석

조경원(Cho Kyung-Won) 이화여자대학교 한국여성연구원 1996 여성학논집 Vol.13 No.-

This study aims at examining the nature and limitations of women's education in Confucian women's classics, which had been read during the Choson Dynasty. Such Confucian women's classics are included as Queen Sohye's Naehun(Lessons for Women), Four Women's Classics(Yusaseo; Yukuy, Yunonyu, Naehoon, Yubum), and other works of the Confucian scholars such as Lee Hwang, Song Siyeol, Lee Dukmoo. The educational content of such women's classics can be classified into four types; self-cultivation, human ethical relationship, education of children, and housework. All these education are characterized by the restrict saperation between wife and husband. Recognizing that there had no been proper women's education except learning skills such as spinning, the female authors of the Confucian women's classics urged women to realize the importance of women's education for becoming the virtuous Confucian women. They did so within the neo-Confucian views of women and world. They want to enlighten women through Confucian ethics, since they believe that the relationship between wife and husband is basic in a well-ordered patriarchal society. In Confucian tradition, maintaining a moral character requires education and constant efforts. This is the same for men and women. Natural differences and labor division between the sexes are justified by lawlike assumptions based upon the doctrine of Yin and Yang. The correspondence between human beings and nature legitimates such a dominant code of Confucian ethics as filial piety, wife's obedience to husband, women's chasity as a natural process. It also takes for it granted that women's different education should be limited to the traditional female roles as daughter, wife, daughter-in-law, and mother. Confucian teachings in the texts exclude women's academic learning and critical thinking, but emphasizes the systematic control and subjugation of women. In this way female authors' arguments for women's education offer the protection for the Confucian ethical code, which was given the logical grounds for the discriminate norms and rules between women and men. Their understanding of women's education help to reproduce the ideology of Confucianism through women's spontaneous consent.

‘생활방식으로서의 민주주의’에 대한 오천석 사상 탐구

조경원(Cho, Kyung Won) 이화여자대학교 교육과학연구소 2014 교육과학연구 Vol.45 No.4

This paper aimed to study Cheon-Seok Oh’s ideas of democracy as “a way of life” and its implications for education. Cheon-Seok Oh’s concept of democracy is clarified through the philosophy of Dewey, which Oh terms “a way of life.” The paper grasps the meanings of democracy as “a way of life” through four concepts: 1) faith in human nature, especially the capacity of intelligent judgment and action, 2) human freedom and equality, 3) social inquiry and social intelligence, 4) the realization of the individual and community life through communication based on everyday experience. The result of discussions indicates that the core meaning of democracy as a way of life implies the importance of community life to guarantee the full development or realization of the individual. Due to the socio-political conditions right after Independence, Cheon-Seok Oh was concerned with Korean democratic educational systems and democratic education in schools. Yet, despite Cheon-Seok Oh’s achievements in implementing democratic education, it is necessary for us to further democratize educational institutions today. This paper also argues for the necessity of expanding our public discussion of education based upon the continuous exploration of social systems as well as educational institutions.

교육개혁조치의 근본이념과 현장 적용성에 대한 연구 : 학교운영위원회 제도를 중심으로 A Stdudy on the School-Site Council

조경원(Kyung Won Cho),정진곤(Jeen Gon Cheong),김용식(Yong Sick Kim) 한국초등교육학회 1997 초등교육연구 Vol.11 No.1

이 연구는 정부에서 발표한 다양한 교육개혁조치 가운데 학교현장에 많은 변화를 가져올 것으로 기대되어 왔던 '학교운영위원회'를 선택하여, 그 제도가 추구하고자 하는 목적과 근본이념이 무엇이며, 과연 그러한 목적이 학교현장에서 원래의 의도대로 시행되고 있으며, 그렇지 않다면 그 원인은 무엇이며, 이를 달성하기 위하여 어떤 방향으로 개선되어야 할 것인가를 탐색하였다. 학교운영위원회 제도의 근본이념과 취지는 이제까지의 교장중심의 독단적인 학교운영에서 탈피하여 학교 사회의 주된 구성원인 교장, 교사, 학부모, 지역사회인사 등이 함께 모여 학교의 주요한 일들을 협의해 가는 '학교운영의 민주화'라고 할 수 있다. 그러나 학교현장에서는 이 제도가 위원의 선출, 안건의 상정과 심의 및 의사결정과정 등에서 원래의 취지대로 운영되지 못하고, 비민주적인 방식으로 운영되고 있다. 그 주된 원인은 제도자체의 미비점, 졸속적인 시행과 준비부족, 제도정착을 위한 노력의 미흡, 학교장의 권위주의적 태도 그리고 학부모의 전통적 교육관과 의식 등에서 찾아 볼수 있다. 이를 개선하기 위해서는 학교 급별, 지역별, 학교별로 다양한 형태의 위원회를 구성하여 운영할 수 있도록 허용하고, 위원의 선출과정과 절차의 준수, 위원들의 역할과 권한에 대한 철저한 교육 등이 이루어져야 한다. Korean government like any other countries believes that his future depends on the quality of education. Most people think that current educational systems are not effectively working and students do not study worthwhile knowledges and skills eventhough they work very hard. Such as increasing world-wide competitiveness, technological development requires educational reform. If the future generation continues to concentrate on memorizing inert and tedious informations in these situations, the nations may face serious danger. The Presidential Committee on Educational Reform was organized in 1994 and tried to reestablish educational system of our country. The Committee suggested many educational agenda. Most people at that time appreciated their efforts and hoped their success. The School-Site Council(SSC)is one of such educational reforms of the Committee. The school is not democratic and parents cannot participate in school government. Only the principal has monopolic power in decision and management of the school. The study is to make clear what the fundamental purpose of SSC is. Even though the Presidential Committe suggested three purposes, enhancing the diversity of schoolings, trying to make parents and teachers participate in school administration, and connecting the school with the community, they can be summarized with making the school democtratic. The study finds out how SSC is democratically organized and performing in school. In other words we want to know whether educational ideal of SSC is really achieved in school or not. However, the answer is negative. The procedures and management of electing the members of the council are, first of all, undemocratic. The council members of the parents do not represent them because very few parents among the whole participate in the election. The members in some schools are appointed by the principal. The principal in some cases ask the council to pass the agenda because they are already informed to the parents. The coucil easily agrees with his asking. Such as an agenda about the management of school curriculum is never argued even though the council is to touch upon it. Why is SSC not so effectively working in school? The members, first of all, do not know what their roles are. Most of them are never heard of them and educated. They only guess that SSC is similar with the past parent association which was organized in order to collecting money from the parents for the development of the school. The second reason is that the principal is very authoritarian in most cases. He or she thinks the council do not know what is going in school and cannot make good decision. Most parents are very obedient and seldom against the principal. How can we make achieve the ideal purpose of SSC? We must allow the diversity of SSC. The school district should make an effort to educate the members what they do for the school. The members are to be elected in such ways to represent the whole parents and they are able to do their roles and work hard.

기계적 합금화로 제조된 Fe_0.92Mn_0.08Si₂의 상변화 및 열전 특성

김영섭,조경원,김일호,어순철,이영근,Kim, Young-Seob,Cho, Kyung-Won,Kim, Il-Ho,Ur, Soon-Chul,Lee, Young-Geun 한국재료학회 2003 한국재료학회지 Vol.13 No.5

In an attempt to enhance phase transformation and homogenization of Mn-doped $FeSi_2$, mechanical alloying of elemental powders was applied. Cold pressing and sintering in vacuum were carried out to produce a dense microstructure, and then isothermal annealing was employed to induce a phase transformation to the $\beta$-$FeSi_2$semiconductor. Phase transitions in this alloy system during the process were investigated by using XRD, EDS and SEM. As-milled powders after 100 h of milling were shown to be metastable state. As-sintered iron silicides consisted of untransformed mixture of $\alpha$-$Fe_2$$Si_{5}$and $\varepsilon$-FeSi phases. $\beta$-$FeSi_2$phase transformation was induced by subsequent isothermal annealing at $830^{\circ}C$, and near single phase of $\beta$-$FeSi_2$was obtained after 24 h of annealing. Thermoelectric properties in terms of Seebeck coefficient, and electrical conductivity were evaluated and correlated with phase transformation. Seebeck coefficient electrical resistivity and hardness increased with increasing annealing time due to $\beta$ phase transformation.
