교육학과 포스트휴머니즘 담론의 임계점에 관한 고찰

우정길 ( Woo¸ Jeong-gil ) 한국교육철학학회(구 교육철학회) 2020 교육철학연구 Vol.42 No.4

포스트-휴머니즘과 포스트휴먼-이즘을 개념적으로 구분하면서 포스트휴머니즘 담론의 지형을 제시하는 데서 시작하는 본 연구는 근래 인문과학 사회과학계의 관심사로 부상한 포스트휴머니즘 담론이 교육학의 논리와 어떻게 유사하고 또한 상이한지를 검토함으로써, 이 새로운 담론을 대하는 교육학의 관점들을 점검하고 있다. 교육학과 포스트휴머니즘 담론 사이의 표면적 유사성은 이 두 가지가 공히 인간의 개선을 목적으로 한다는 사실 그리고 결핍존재론과 이원적 인간론을 그 논거로 활용하고 있다는 데 있다. 아울러 교육학은 광의의 휴머니즘에 기반한 계몽주의를, 그리고 포스트휴머니즘 담론은 미완창조론과 자유의지론, 계몽주의와 진화론, 자유주의 우생학과 기술낙관주의의 자의적 조합을 사상적 배경으로 하고 있다. 그러나 교육학이 추구하는 인간의 개선이 인간다움의 실현 또는 인간적인 인간의 구현에 있다면, 포스트휴머니즘의 목적은 인간을 초월한 인간의 추구에 있다는 점에 있으며, 아울러 이러한 목적의 실현을 위하여 교육학은 교육이라는 전통적 방법론을 그리고 포스트휴머니즘은 향상(enhancement)이라는 이름으로 총칭되는 현대의 공학기술적 방법들을 활용하는 데 그 차이가 있다. 이상의 비교에 근거하여, 본고는 이 둘의 차이의 의미가 교육학의 관점에서 진지한 성찰의 대상이 되어야 한다는 주장을 피력한다. 아울러 포스트휴머니즘이라는 새로운 담론을 마주하는 교육학이 포스트모더니즘 논쟁 이후 교육학의 주요한 패러다임 중 하나로 주목받았던 관계중심성 논의들에 관심을 기울여야 할 것 그리고 더 개방적 포용적이면서도 전통적 인간성 인류성 개념에 충실한 교육의 개념을 새롭게 디자인해 나가야 할 것을 제안하고 있다. Beginning from the differentiation between Post-humanism and Posthuman-ism to make an overview on the topography of the discourses of posthumanism, this study investigates the similarity and difference in its ground and argument between the traditional science of education and posthumanism which has become one of the major concerns in the field of human science and social science in the last decade. It also examines the basic perspectives of the traditional science of education confronting with these new discourses. The superficial similarity is that they both aim at an improvement of human being and that they use the theory of deficit being (Defizitwesen, Mangelwesen) as well as the dualistic anthropology as a ground for their argument. However, the science of education is deeply rooted in the spirit of humanism and enlightenment in a broad sense, while posthumanism is rather a combination of the theory of unfinished creation and a doctrine of the free will, and a mixture of the evolution theory, eugenics, and techno-utopianism. Critical differences can be found in their goals. In case of education, the goal is the realization of humanity, namely being and becoming fully-human; in the case of posthumanism, it is the pursuit of the betterment of humanity in the sense of making human better than human, i.e. beyond human through the NBIC-methods of enhancement. On this ground, this study stresses the view that these differences need to be the object of the serious reflection from the educational perspective. And it proposes that the contemporary science of education should pay more attention to the objects between education and enhancement, namely the areas of supplement, correction and therapy which have been marginalized in the traditional education. It is time for the contemporary science of education to have more eye on the relationship-centered paradigm which has been the main issue after the era of postmodernism. It also needs to redesign the concept of education in ways to be more open and inclusive towards the objects of supplement, correction and therapy, as well as still to remain faithful to the main idea of humanity at the same time.

Studies of NO Adsorption on Proton-Irradiated MgO Surfaces

Jeonggil Lee,Jae-yong Kim,Jae-Kyun Jeon,Kyeryung Kim,Sang-pil Youn,Sangwha Lee,Youn Man Lee,Jeongha Kim,신관우 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.3

Recently, adsorption studies of gases for various adsorbents have been intensive because they are useful in probing the fine structure of the surface. Meso-sized MgO(100) powder was irradiated by a proton beam with a high energy of 35 MeV. Transmission electron microscope (TEM) investigations revealed no structural change of the MgO powders after irradiating with the proton beam. After proton beam irradiation, NO gas isotherm adsorption data were recorded from the same sample below the triple point (109.8 K). The results revealed that there was no hint of multi-isotherm step formation, which indicates the creation of an atomic layer of NO molecules. Instead, only a monolayer of NO molecules was obtained. It is understood that pre-existing unwanted impurities, such as water and carbon-related organic gases, hinder the formation of atomic layers in a regular fashion on the MgO powder surface. By comparing NO adsorption data from the pure and the proton-irradiated MgO samples, we were able to calculate the surface-related thermodynamic characteristics, including the 2-dimensional compressibility and the heat of adsorption.

Assessment of Various Culture-dependent and-independent Methods for Soil Microbial Numbers

( Jeonggil Lee ),( Man Jae Kwon ) 대한지질공학회 2019 대한지질공학회 학술발표회논문집 Vol.2019 No.2

Shallow subsurface environments contain relatively high amount of organic matters for bacterial growth and activity. Thus, broad and high number of bacteria have been reported depending on a variety of physical and chemical properties in the subsurface environments such as the types and concentrations of organic matter, temperature. Microbes make contribution to the material circulation via an electron transport. Because of these specific characteristics and the inability to move farther in the subsurface environments, the bacterial number can represent one of the key characteristics of the subsurface environments. We investigated both culture-dependent methods and culture-independent/direct counting methods. Effectiveness and accuracy of each enumeration method was tested with 72 soil samples collected from local farm site at three different depths. We also investigated the effect of sample storage time, storage temperature and sonication time on the number of bacteria. Soil samples for microbial counts should be stored at 4 °C and measured within 24 hours because the number of bacteria decreased overtime in the room temperature. Optimal sonication time for soil sample pretreatment was 5 min MPN was optimal (i.e., quick, simple, and reliable) among the culture-dependent methods for soil microbial numbers. However, the number of bacteria determined by MPN was 1-2 orders lower than that by culture-independent methods (direct counting methods) because of the limitation of MPN, incapability of counting anaerobic bacteria. The results suggest that the number of bacteria (aerobic vs anaerobic, live vs dead) in subsurface environments should be evaluated carefully by both culture-dependent and -independent methods.

Enabling on-board deep learning model training for mobile and embedded systems

JeongGil Ko(고정길) 한국생산제조학회 2021 한국생산제조시스템학회 학술발표대회 논문집 Vol.2021 No.7

On-device deep neural network model training holds the potential to enable a rich set of data privacy-aware and infrastructure-independent personalized mobile applications [1-3]. However, despite recent advancements in mobile and embedded platform's hardware, locally training a complex deep neural network is still a non-trivial task given its resource demands. Such capability can be used to exploit new machine learning concepts which include federated learning and distributed learning. In this work we show that the limited dynamic memory budgets on mobile platforms is the main constraint, and propose meMon as a framework for efficiently managing mobile memory resources for deep neural network training. Specifically, meMon is cored on a heuristic objective function that identifies neural network activations that are i) easy-to-recompute, ii) consumes large memory spaces, and iii) with weak dependency, so that they are prioritized to be removed from the memory when memory resources are scarce. meMon is implemented in CUDA and will be provided as open source for the research community. We evaluate meMon via hardware benchmark-based emulations and real implementations on the Samsung Galaxy S10 (Android 10) and NVIDIA Jetson TX2. Our evaluations show that meMon enables local training for five state-of-the-art deep learning models (BERT, ResNet-152, DenseNet-169, Stacked LSTM, DCGAN) by reducing the required memory by more than five-fold and speeds up the training process by two-fold compared to a baseline approach. We also show that meMon successfully adapts to dynamic memory budget variations, suggesting its robustness in real-world use cases.

Jeonggil Lee(이정길) 한국로고스경영학회 2021 로고스경영연구 Vol.19 No.3

본 연구는 기술평가모형을 통한 중소기업의 기술사업위험 예측에서 거시경제변수 도입의 유용성을 분석하였다. 분석은 기술평가변수만을 고려한 경우와 거시경제변수를 추가적으로 포함한 경우로 구분하여 실시하였다. 본 연구의 분석결과는 다음과 같다. 먼저, 기술평가변수는 기술평가기관이 기술평가모형에 적용하여 이루어지는 평가점수로서 기업의 기술사업위험을 예측함에 있어서 유용한 것으로 평가된다. 다음으로 거시경제변수를 기술사업위험 예측모형에 포함하여 분석할 때 AUC 값이 더 높은 것으로 나타나, 거시경제변수를 포함한 모형에서 기술사업위험 예측 능력이 개선됨을 보여준다. 본 연구의 결과는 거시경제적 상태가 국내 중소기업들의 기술사업위험에 영향을 미침을 보여준다. 뿐만 아니라 은행, 보증기관 등 금융기관들에게는 거시경제 변수를 기업의 기술사업위험 예측모형에 포함함으로써 예측능력을 개선하고, 그 결과, 손실을 축소할 수 있음을 보여준다. 본 연구는 이상과 같은 연구결과에도 불구하고 다음의 한계를 갖고 있다. 먼저, 기술평가변수를 소항목 차원으로 낮추어서 기술사업위험 예측에서의 적정성을 검토할 필요가 있다. 다음으로 중소기업의 개별 기술사업위험이 아닌 중소기업의 전체 월별내지 분기별 기술사업위험 자료를 사용하여 이들 기술사업위험 통계와 거시경제변수 간의 관계를 분석할 필요가 있는 것으로 보인다. This study analyzed whether it is useful to include macroeconomic variables in addition to the technology assessment. The results are summarized as follows: First, the technical rating variables are useful in predicting the possibility of an entity"s bankruptcy. In this study, significant results are derived even if it is applied to predict technology commercialization risk using sub-subcategory variables. Next, when introducing macroeconomic variables, macroeconomic variables are also evaluated to contribute to the improvement of the insolvency prediction. In general, macroeconomic variables are indicators of the overall downturn and activity of the economy, which directly and indirectly affect the financing, investment and profitability of individual entities. Despite these findings, this study has the following limitations: First of all, it may be useful to use the sub-subcategory technical evaluation variables. Next, it seems necessary to analyze the relationship between the default rate and macroeconomic variables using monthly or quarterly default rate data of SMEs.

이정길(Jeonggil Lee) 한국자료분석학회 2020 Journal of the Korean Data Analysis Society Vol.22 No.2

본 연구는 2011년부터 2018년까지 국내 상장기업의 성장률 결정요인을 패널회귀모형을 통해 분석한 것으로 주요 연구결과는 다음과 같다. 첫째, 자기자본순이익률은 성장률에 유의적인 양(+)의 영향을 미치는 것으로 나타나, 수익성은 기업에 대한 투자동기부여, 내부자금조달의 확대 등을 통해 기업 성장에 기여함을 보여준다. 둘째, 레버리지 비율도 성장률에 유의적인 양(+)의 영향을 미치는 것으로 나타난다. 이는 기업들이 외부차입을 통해 확보한 자금을 활용하여 기업의 성장률을 제고하는 것으로 해석된다. 셋째, 연구개발투자와 유동비율의 경우 가설과는 반대되는 결과를 보여주었다. 이에 대해서는 향후 타 성장률 변수에 대한 검토, 대용변수의 변화 등을 통해 추가적인 검토가 필요한 것으로 보인다. 넷째, 기업 규모에 따른 수익성의 성장성에 대한 영향의 경우, 성장률의 산출방식에 따라 상이한 결과를 보여주어, 일관성 있는 결과를 보여주지 아니하였다. 본 연구는 성장률에 대한 영향요소를 재무적인 요소로 제한한 한계가 있다. 향후 연구에서는 비재무적 요인을 발굴, 이 요소들의 성장률에 대한 영향을 분석할 필요가 있는 것으로 보인다. This study analyzed the determinants of listed companies’ growth rate in Korea from 2011 to 2018. The main findings are as follows. First, the return on equity appears to have a significant positive (+) effect on the growth rate. This means that a firm’s high profitability contributes to its growth in such a way to motivate its investment and to expand its internal funding. Second, leverage ratios also appear to have a significant positive (+) impact on growth rates. This means that the corporate growth rates become higher by making use of funds obtained through an increase in leverage. Third, the impact on the growth potential of profitability according to the size of the enterprise, R&D investment, and the growth rate of the current ratio are showing different outcomes from the hypothesis. This study limits the impact factors on growth rates to financial factors. In future research, non-financial factors need to be applied for their impact on growth rates.

도시철도차량의 치수최적설계 및 구조체 형태에 따른 경량화 연구

조정길(Jeonggil Cho),김준우(Junwoo Kim),구정서(Jeongseo Koo),정현승(Hyunseung Jung) 한국철도학회 2013 한국철도학회 학술발표대회논문집 Vol.2013 No.11

하박국은 사회경제적 문제를 개인적 믿음의 문제로 치환하는가?

이정길(Jeonggil Lee) 한국로고스경영학회 2016 로고스경영연구 Vol.14 No.4

본 연구는 구약성경 하박국서 제2장 4절의 후반부(합2:4b)를 중심으로 하박국서에서 말하는 “믿음”의 의미와 내용이 무엇인지를 분석한 것이다. 이러한 분석을 함에 있어서 본 연구의 목적은 합 2:4b의 사회경제적 측면을 드러내는데 있었다. 이를 위해 본 연구는 하박국서의 관련 본문과 신약 로마서 등의 관련 본문을 중심으로 주요 키워드에 대한 어의분석을 실시하였다. 또한 하박국 당시의 사회경제적 환경에 대한 역사적 배경을 분석하였다. 이상의 분석을 토대로 한 본 연구의 결과는 다음과 같다. 첫째, 합 2:4b의 배경을 드러내는 키워드를 분석했을 때에, 이 본문의 배후에는 개인적 차원의 신앙의 문제가 아니라 사회경제적 차원의 문제가 있음이 나타난다. 둘째, 하박국서의 시대적 배경을 분석해 보면 그 당시 유다가 전쟁패배 후 막대한 배상금을 부과받았으며(왕하 23:33), 백성들이 과중한 세부담을 안고 있었음을 알 수 있다(왕하 23:35). 이는 하박국의 절규의 이면에 백성들의 고통이 있었음을 의미한다. 셋째, 쩨데크에 대한 기존 연구들을 분석한 결과 하박국 본문에서 “의”의 의미를 갖는 쩨데크는 핵심적인 요소는 사회적 정의라는 것이다. 넷째, 하박국에서 “믿음”은 단순한 지적인 동의를 넘어 하나님의 은혜를 경험한 의인이 그 은혜를 기반으로 공의를 행하는 신실한 모습을 의미하며, 이러한 삶의 모습에는 사회경제적 차원의 공의가 당연히 포함된다는 점이다. 다섯째, 결론적으로 하박국이 말하는 “의”와 “믿음”은 개인적 차원을 넘어, 사회경제적 차원을 갖는다는 것이다. 그리스도인은 “믿음”을 개인적인 삶의 영역, 즉 사적인 영역으로 제한하지 않고, 공적 영역, 즉 사회경제적 공의의 영역으로 나아가야 한다. This study analyzes what Hab.2:4b means and what the contents of the “faith” mentioned in Habakkuk are. The purpose of this study is what is the socioeconomic aspect of Hab 2:4b. The results of this study are summarized as follows. First, the keyword analysis of Hab 2:4b reveals that the background of Habakkuk is not a matter of personal faith problems but a socioeconomic matter. Second, the historical background of Habakkuk reveals that Jews had charged a huge amount of fines whenever suzerain changes after they had lost the war against enemies at that time. Thereby, the people had a heavy tax burden. It means that there has been such a pain in the backside of the people of Habakkuk"s screams. Third, the results of analyzing on existing research of Habakkuk shows that key factor of Tzedek is social justice. Fourth, in Habakkuk, “faith” is not merely an intellectual agreement. The righteous person in Habakkuk have experienced the grace of God, and he have been faithful to perform God’s Words. Here, God’s Words include the socioeconomic dimension. Fifth, conclusion from analysis on Habakkuk and the related Words says that “righteousness” and “faith” are beyond the individual level, and has a socio-economic dimension. It means that Christian’s faith should not be limited to the private sphere. The faith of Christians must go beyond the private sphere to the public sphere and be able to exert influence on the socioeconomic aspects.
