교육활동은 학습자에게 의미있는 감각정보의 생성을 유도하며 시작된다. 이러한 감각정보가 학습자의 신경계에 어떠한 장기기억을 형성하게 되느냐에 따라서 교육활동의 성과 또한 천차만별로 다르게 나타날 수 있다. 이런 의미에서 감각정보의 기억형성과정은 학습자가 교육활동의 목표를 얼마나 달성했는지와 밀접한 연관성을 지니게 된다. 교육활동은 학습자의 신경계에 교육적으로 의미있는 변화를 일으키려는 의도적인 활동이라고 볼 수 있는 것이다. 그러므로 교육활동의 계획과 준비 및 진행과 검증 등에서 감각정보의 기억형성과정이 학습자의 몸속 신경계에서 어떻게 이루어지는지 중요하게 고려될 필요가 있다. 따라서 본 연구는 감각정보의 기억형성과정에 대한 신경과학적 이해를 바탕으로 교육신경학적 해석을 진행하고 적용의 예시를 제안하고자 하였다. 감각정보는 감각자극에 대한 개별 신경세포들의 흥분과 억제를 통해 우리 몸 신경계의 병렬적 처리와 위계적 처리 간 상호작용에 기반하는 통합적 양상을 거쳐 생성된다. 그리고 이렇게 생성된 감각정보의 기억형성과정은 신경세포들 간 시냅스 연결 강도가 강화 또는 약화되는 변화를 기반으로 신경세포군 및 뇌 영역들 간 상호작용의 양상이 통합되어 장기적으로 지속되는 변화를 거치게 되면서 이루어진다. 이러한 신경과학적 이해를 바탕으로 본 연구에서는 감각정보의 기억형성과정에 대한 유형을 서로 다른 신경회로의 활동에 기반하여 이루어지는 외현적 기억형성과정과 암묵적 기억형성과정 두 가지로 구분하고, 감각정보의 기억형성과정 원리를 효율적 선택을 위한 경쟁의 원리와 상호작용에 기반한 통합의 원리로 이해하여 교육신경학적 해석을 진행하였다. 그리고 교육신경학적 해석의 교육적 시사점과 적용의 예시를 제안하고 교육학 연구 지평의 확대를 위한 새로운 연구의 필요성을 제언하였다. Educational activities begin by inducing learners to produce meaningful sensory information. The performance of educational activities can also vary widely depending on long-term memories formed by such sensory information in the nervous systems of learners. In this sense, the memory formation processes of sensory information are closely related to how much the learner has achieved their educational activity goals. Educational activities can be viewed as intentional activities that bring about meaningful educational change to the nervous systems of learners. Therefore, importance needs to be placed on how memory formation processes of sensory information take place in the nervous systems of learners in the planning, preparation, progress, and verification of educational activities. Thus, this study attempted to make educational neurological interpretations and present examples of application based on a neuroscientific understanding of the memory formation processes of sensory information. Sensory information is generated through integrated aspects based on interactions between the parallel processing and hierarchical processing of our body's nervous systems through the excitement and inhibition of individual neurons regarding sensory stimuli. Also, the memory formation processes of sensory information generated this way are achieved through changes that continue to occur for long periods of time as aspects of mutual interaction among neuron groups and brain domains integrate based on changes that strengthen or weaken synaptic connection strength among neurons. Based on such neuroscientific understanding, this study categorizes the memory formation process types of sensory information into explicit memory formation processes and implicit memory formation processes that take place based on the activities of respectively different neural circuits and it conducted educational neurological interpretations by understanding memory formation principles of sensory information as principles of competition for efficient choices and principles of integration based on interaction. Also, it presents educational implications of educational neurological interpretations along with examples of application and proposed the need for new research on the expansion of educational research horizons.

Recently, regulations on automobile exhaust gas emission are being strengthened. Accordingly, automobile exhaust gas emissions are expected to decrease and continue to decrease. On the other hand, many countries do not yet consider the emission of non-exhaust air pollutants from automobiles as important. Automobile non-exhaust substances are classified into three categories: tire dust emissions, brake wear emissions, and road scattering dust. In particular, in the case of tire dust, research results exist that pollutant emissions increase as the weight of a vehicle increases. Since the weight of trucks varies according to the load and the load along the axles is also different, it can be expected that the emission of PM10 from the tire dust will be different depending on the loading method. Therefore, this study was conducted on the amount of PM10 generated in tire dust considering the axle load of the truck according to the loading method. However, it was confirmed that the total amount of PM10 was less than that all loads are loaded in the front or rear when the load was evenly distributed in the front and rear of the cargo compartment. In particular, if the load is distributed evenly in the front and back of the cargo compartment and the load in the front part is divided into 2 to 6 and loaded, as the number of divided loading increases the amount of PM10 generated decreases. And when the load is divided into 6 pieces, the total amount of PM10 generated is 0.3952g, the minimum value. If the load is divided into 6 or more and loaded evenly, the total PM10 generated continuously increases and converges to about 0.3964g.

Evapotranspiration (ET) is one of the basic component of the hydrologic cycle and is essential for estimating irrigation water requirements. In this study, artificial neural network (ANN) models for reference crop evapotranspiration (ET0) estimation were developed on a monthly basis (May~October). The models were trained and tested for Suwon, in Korea. Four climate factors, daily maximum temperature (T_max), minimum temperature (T_min), rainfall (R), and solar radiation (S) were used as the input parameters of the models. The target values of the models were calculated using Food and Agriculture Organization (FAO) Penman-Monteith equation. Future climate data were generated using LARS-WG (Long Ashton Research Station-Weather Generator), stochastic weather generator, based on HadCM3 A1B scenario. The evapotranspirations were 549.72 mm/yr in baseline period (1973~2008), 558.08 mm/yr in 2011-2030 (2020s), 593.03 mm/yr in 2046-2065 (2055s), and 641.07 mm/yr in 2080-2099 (2090s). The results showed that the ANN models achieved good performances in estimating future reference crop evapotranspiration.

이은정 ( Eunjeong Lee ) 한국환경영향평가학회 2017 환경영향평가 Vol.26 No.1

최근 우리나라 유역관리정책을 보면, 조류 중점관리 지류 선정, 지류총량제 시범적용 등 중앙정부주도의 본류중심 관리에서 소단위 지류·지천 관리를 위한 기반을 마련하고 있다. 이러한 시점에 발맞춰 소단위 하천을 대상으로 일상적, 자발적, 맞춤형 관리가 가능하도록 주민참여형 유역관리방안을 설계 및 제안한 후, 주민이 참여하는 하천모니터링 활동을 무심천유역에 시범적으로 적용해 보았다. 총 30개 구간으로 구분하여 주민 1명씩 배치하여 격주로 총 10회동안 모니터링을 수행한 결과, 문서화되지 않은 실제 유역현황을 파악할 수 있었다. 특히, 사각지대의 오염원 실태를 통해 소단위유역별 관리의 필요성을 확인할 수 있었으며, 이러한 조사 내용이 각종 계획에 반영될 수 있는 상향식 접근이 가능한 발판을 마련하는 것이 유역관리를 위한 선행조건으로 판단된다. Recently, Looking at the watershed management policy in Korea, It is preparing to manage sub-watershed and tributary from the government-led mainstream management, such as the selection of algae focused management tributary, application of tributary-TMDLs. At this point, this study is attempted to propose the residents participatory watershed management methods that is possible daily, voluntary and customized management in the sub-watershed. As a results, through this study, we found out the importance of sub-watershed unit based watershed management because of the pollutants in blind spot. It is the prerequisite for watershed management to arrange practicable bottom-up approach that these investigated contents can be reflected in the various planning.

이은정(Lee, EunJeong),이윤진(Lee, YounJin) 한국색채학회 2021 한국색채학회 논문집 Vol.35 No.4

In branding and brand management, forming a close emotional bond with consumers is crucial. In the pursuit of cultivating an attachment relationship with consumers, the choice of color is important in the process of exploring and understanding the consumer’s “self”. This study examined whether color preference of individuals can help understand their self. Eighty(42 males, 38 females) individuals with an average age of 35(SD=7.46) years participated. Their personality was classified, and their preferred colors were investigated using the Enneagram personality test, which is a self-diagnostic tool. Descriptive statistical analysis was conducted using PASW Statistics 18 followed by a focused literature review to contextualize the results. It was found that the “body center” type preferred cold colors, and the “head center” type preferred warm colors. The “heart center” type accepted both cold and warm colors. In addition, a pattern of the expression of the self, as reflected in the preferred color, was derived. With respect to the mental aspect, the preferred color was related to pursuing the will as opposed to the expression of the self. In the emotional aspect, the preferred color was related to generating a stimulus that controls the problem of latent emotions. In summary, this study derived an understanding of how preferred colors express the mind and emotions of the self. The results suggest that it is possible to search for the self by analyzing color preference, which reflects the self to an extent.

인류학적 개발사업과 평가받지 못한 결실: 미얀마에서 진행된 국제개발 협력사업을 중심으로

이은정 ( Lee Eunjeong ) 한국문화인류학회 2017 韓國文化人類學 Vol.50 No.3

국내에서 시도된 ‘인류학적 개발’은 ‘한국국제협력단(KOICA)’이 대학을 국제개발협력의 새로운 주체로 등장할 수 있도록 기회를 제공한 것이 그 배경이다. ‘인류학적 개발’은 문화상대주의와 주민 참여를 중요시하는 방식으로서, 기존의 개발사업이 양적지표에 치중되어 있고, 하향식으로 이루어지는 것에 대한 비판을 바탕으로 시작되었다. ‘인류학적 개발사업’은 미얀마의 인류학자들과의 협업으로 진행되었고, ‘인류학’과 ‘개발 경험’을 바탕으로 선발한 자원활동가들을 현장에 파견했다. ‘마을조사’는 마을주민들의 '사회문화자산'을 존중하고 라포를 형성하는 방식으로 진행되었고, ‘지역 지식’을 축적하고 마을 구성원들의 활동을 지원하기 위한 ‘지역지식센터’를 대학과 마을의 구성원의 적극적 참여를 바탕으로 설립했다. 반면, 개발사업의 평가는 교수진의 참여나 사업의 양적 내용을 중시하는 방식으로 진행되었고, 마을주민들의 참여나 의견 수렴 등은 평가에 적극적으로 반영되지 못해 사업은 조기 종료의 국면을 맞이한다. 사업의 종료 이후에도 현지 대학과 마을의 구성원들은 센터를 중심으로 적극적으로 활동을 꾸려나가고 있는데, 이는 ‘인류학적 개발’의 과정에서 대학과 마을의 구성원의 참여가 지속적으로 이어진 결과라 볼 수 있다. 이러한 ‘평가받지 못한 결실’은 인류학자, 마을주민, 자원활동가들의 지속적인 교류 등으로 이어지고 있다. 이 논문에서는 인류학적 개발의 기획과 사업의 진행, 사업성과, 지원기관과 인류학자들의 엇갈린 평가, 그리고 사업의 종료 이후로도 지속되는 ‘인류학적 개발’의 의미와 결과에 대해서 논의하고자 한다. An ‘anthropological development’ has been attempted in Korea led by anthropologists. The background is that the Korea International Cooperation Agency (KOICA) provided opportunities for universities to emerge as the new agents of international development cooperation. Anthropologists have argued for ‘advancement’ rather than ‘development’ and planned an ‘anthropological’ development cooperation project that fosters the development resources of villages based on local knowledge. Furthermore, the anthropologists who have interests in the field are providing more chances to the future professionals. The project was conducted through collaboration with a university in Myanmar and volunteers were sent based on anthropological knowledge and developmental experience. Volunteer activists surveyed local knowledge and heritage by forming rapport with local activists and villagers, and built the ‘local knowledge centre’ in a university and a village to accumulate local knowledge and support the activities for village members. Due to the project evaluation system, which emphasizes the project’s outcome more than the recipient’s motivation, the project had received a negative evaluation, and as a result the project was ended within the year. However, since the end of the project, interactions among local anthropdogists, volunteer activists and village residents have continued, and ‘unevaluated outcomes’ are continuing through relationships and use of centers. This paper provides a discussion of the meaning and results of anthropological development planning, progress, and evaluation carried out by KOICA and the project team, and describes the outcomes after the end of the project.

The purpose of this study is to establish a framework for cultural education. In order to do this, I examine previous research and also consider cultural education theoretically. I criticize the use of discordant terminology and theoretical approaches in cultural education research. I attempt to integrate the various different forms of cultural education. For this purpose, I suggest a new framework for cultural education and argue that a general theory of ‘Intercultural Education’ is required. In conclusion I revise the scope of ‘Korean Education’, and suggest that further research on ‘Korean Education and Cultural Education of Korea as an Intercultural Education’ is required.

교육신경학에 기초한 영재성과 창의성의 관계

이은정 ( Lee Eunjeong ) 한국청소년학회 2022 청소년학연구 Vol.29 No.11

The relationship between giftedness and creativity has been understood from diverse perspectives according to the approach. Because both concepts of giftedness and creativity are multidimensional and complex, it is difficult to define them simply in a single aspect. As a matter of fact, it can be seen that both giftedness and creativity appear because they are humans’ higher-order properties related to multidimensional and complex actions of the nervous system including the brain. However, there is still not enough foundation on which we can discuss the relationship between giftedness and creativity from an educational perspective by associating it with the actions of the nervous system. This study attempted to reconsider the relationship between giftedness and creativity grounded on the perspective of Educational Neurology to build a bridge between Education and Neuroscience. To address the goal, based on the perspective of Educational Neurology, this study discussed the mutual relationship between general understanding and neuroscientific understanding of the relationship between giftedness and creativity. Also, based on the discussion, this study attempted to present useful implications for education. This study is significant as a new foundation to explore the nature of the multifaceted and complex characteristics of giftedness and creativity continuously in association with the properties of the nervous system itself grounded on the perspective of Educational Neurology.

Understanding the association between color preference and physiological aspects is crucial from the point of view of the mind. This study investigated the relationship between color preference and constitution. The results helped develop an understanding of the physiological, psychological, and emotional characteristics reflected by the preferred color. Eighty(42 males, 38 females) individuals with an average age of 35(SD=7.46) years participated. Descriptive statistical analysis was performed using PASW Statistics 18, and keyword frequency analysis was conducted using color expression. A focused literature review was undertaken to contextualize the results. It was found that yellow was preferred for the “Geumsu(Sympathicotonia)” type, and red was preferred for “Mokto(Vagotonia)”. These two groups showed a positive response to color stimulation in the direction of controlling their innate physiological conditions when their personality and psychological tendencies were expressed to the outside world. The results suggest that innate physiological characteristics are a determinant of color preference, and color preference is related to the need for color stimulation.
