This study aimed to examine the extent to which organizational support influenced teachers’ digital literacy through teachers’ interpersonal stress and collaboration among teachers for online teaching in preschools during Covid-19 pandemic. Teacher’s digital literacy is an essential competence of teacher’s readiness for virtual educational paradigm in the future. This study aimed to highlight how to promote teachers’ digital literacy especially focused on collaborative and supportive organizational culture. In this study, a sample of 222 preschool teachers participated and self-reported through online questionnaires on organizational support, their interpersonal stresses, collaboration among teachers for on-line teaching and their digital literacy. Data were analyzed using SEM in Mplus 8.1. Overall, higher levels of organizational supports predicted higher levels of teachers’ digital literacy through higher levels of collaboration for online teaching. Additionally, higher levels of organizational supports predicted teachers higher levels of teachers’ digital literacy through lower levels of teachers’ interpersonal stresses and higher levels of collaboration among teachers for online teaching. The results suggest that efforts to build successful partnership among teachers under organizational supports can be promising target in continuing educational policies to enhance teachers’ readiness in future virtual educational environment. 본 연구는 코로나19 팬데믹 상황에서 유아교육기관의 전문성 지원환경이 교사의 대인관계 스트레스와온라인수업을 위한 교사협력을 통해 유아교사의 디지털 리터러시에 미치는 영향을 조사하고자 하였다. 본 연구는 가상플랫폼을 활용한 미래 교육 패러다임에서 필수적인 교사 준비도라고 알려진 디지털 리터러시를 촉진하는 방안을 모색하고자 하였다. 특히, 전문성을 지원하고 교사 간 긍정적인 관계를 형성하는 유아교육기관 내 협력모델의 중요성을 강조하고자 하였다. 본 연구는 222명의 유아교사가 참여하여유아교육지원의 전문성 지원환경, 대인관계 스트레스, 온라인수업을 위한 교사협력 및 디지털 리터러시에 대해 온라인 질문지로 자기평정을 하였다. 본 자료는 Mplus 8.1을 사용하여 구조방정식 분석을 실시하였다. 그 결과, 높은 수준의 유아교육기관의 지원환경은 온라인수업 준비를 위한 교사협력을 높이고교사 디지털 리터러시를 촉진하는 것으로 나타났다. 또한, 높은 수준의 유아교육기관의 지원환경은 교사의 대인관계 스트레스를 낮추고 온라인수업 준비를 위한 교사협력을 높여 최종적으로 유아교사의 디지털 리터러시를 촉진하는 것으로 나타났다. 본 연구는 가상플랫폼을 활용한 미래 유아교육 과정에서의 교사준비도인 디지털 리터러시는 유아교육기관에서 교사 전문성을 적극적으로 지원해주고 교사 간의 유대감을 조성하며 협력적인 파트너십을 성공적으로 구축할 때 향상됨을 확인하였다. 이는 더 나은 미래 교육환경을 대비하여 유아교육기관이 교사 전문성 지원을 적극적으로 하도록 돕는 지원예산 확충과 교사간 공동체 협력 활성화를 위한 정책 마련의 노력이 중요함을 시사한다.

아부 바크르 알바그다디 연설문에 나타난 이슬람국가(IS)의 정체성 연구

김재희 명지대학교(서울캠퍼스) 인문과학연구소 2016 인문과학연구논총 Vol.37 No.2

The purpose of this paper is to analyze and find the identity of the Islamic State (IS) described in the remarks delivered by the IS caliph Abu Bakr al-Baghdadi. It also studies the concrete roadmap of the IS for realizing its goal. The identity of the IS is shown in the four remarks given by al-Baghdadi in June 2014, November 2014, May 2015 and December 2015. Analysis on these speeches revels two features of the IS, the Sumnni Islam and Mujahideen. The future goal of the IS shown in the remarks is the “establishment of an Islamic caliphate.” To accomplish this goal, in his speeches, al-Baghdadi encourages the hijra (migration), establishment of an Islamic community, jihad and destruction of idols as well as expansion of territory. Although his remarks repeatedly touch upon the aforementioned identity and goal, they also focus on specific issues considering then-surrounding circumstances. In this light, analysis on these speeches can be useful source for studying the circumstance of the IS in detail. This paper, therefore, aims to find measures taken by the IS to accomplish its goal by translating and analyzing the texts of al-Baghdadi's remarks, thereby studying the identity of the IS and sub-categorizing the remarks by theme.

The purpose of this paper is to prove the effect of the face change by the shoulders and the pelvic girdles balance (called Body-4) which correct 4-points of them to be balanced. It has compared 9-adult women in 30s and 40s with the change of left and right mandible angles and the ratio of left and right zygomatic bones in the face. The results provided above can briefly state as follows. 1. This paper observed the faces of the participants after Body-4 practice of 5-times of treatments, 10-times of treatments and before its treatments. It conducted the F and t-test by the analysis of variance whether it is significantly different. The results by F-test have showed F=10.822(p<.001) in Glabella, F=7.596(p<.05) in Manton, F=4.300(p<.05) in middle face distance. The results by t-test have showed t=2.880(p<.05) in Glabella, t=2.492(p<.05) in length, t=2.099(p<.05) in angle of Manton, t=2.137(p<.05) in middle face distance. 2. This paper observed the body posture through the F and t-test by the analysis of variance to testify the change of the shoulders and the pelvic girdles after the Body-4 practice of 5-times of treatments and 10-times of treatments and before its treatments. The results by F-test have showed F=5.521(p〈.05) in length, F=5.816(p〈.05) in angle of Coccyx, F=34.392(p〈.001) in Both acromions of difference, F=8.618(p〈.01) in middle acromions distances. 3. The expectation about the effect before Body-4 practice, the satisfaction degree of the change about the body posture after its treatments and the satisfaction degree of the before-treatment have presented the highest score as the average of 4.33, the average of 4.30 in the face change and the average of 4.19 in the body posture. 4. The satisfaction degree after treatments between the body posture and the face change with r=0.819(p<1) had the correlation with the significant positive. 5. The satisfaction degree with the average of 4.30 as a whole has been higher than medium grade in the satisfaction degree of face change by category. 6. The complexion to brighten and the satisfaction of the face change with the average of 4.67 have showed the highest score. From the above evidence, the Body-4 therapy has established the effect of shrinking the face and balancing it as well as the balance of the body posture through correcting the shoulder and the pelvic girdles. It offers the grounds that body improvement is prior to the face-oriented treatments to get the beautiful appearance and to solve the problems such like the face shrinking, facial asymmetry, wrinkle and pigmentation.

포스트휴먼 사회를 사유하기 위한 하나의 청사진: 질베르 시몽동의 기술-정치학

김재희 범한철학회 2014 汎韓哲學 Vol.72 No.1

The influence of technology which transforms humans instead of their surrounding environment is accelerating posthumanization. But is the posthuman society that science-fiction imagination and technological deterministic futurology altogether portray reasonable? Can posthuman be reduced to cyborg model (mechanical prosthesization, biotechnological manipulation, digital embodiment, etc.)? Simondon's techno-politics suggest a new blueprint and conceptual tools that are useful when thinking about the upcoming posthuman society. According to Simondon, the possibility of humans overcoming their physical-biological condition lies in the transductional capacity of the technological objects to realize the pre-individual potentiality within the human individual as an organism into the transindividual collectivity. Posthuman is not merely a technological effect; it occurs along with the ‘weight of nature' that exists within humans. Technology, not as prosthetic appliance that reinforces deficient human but as a medium that actualizes human potential, enables the new structuralization and ontological leap of human society. Simondon's insights such as technological alienation which cannot be reduced to economical alienation or labor problem, communication of information, the importance of education of technology that cannot be covered through liberal humanities, and transindividual collectivity formed through technological activity show the techno-political conditions which should be noted along the transition to the posthuman society. Before judging whether cyborgization of human is justifiable or not, we should question the reason why human transform into ‘human-machine ensemble' and wish to transit into posthuman society from a new perspective. In this paper, I will explore how Simondon's techno-politics provide such possibilities. 인간을 둘러싼 환경이 아니라 인간 자신을 변형시키는 과학기술의 영향력이 인간 사회의 포스트휴먼화를 가속화하고 있다. 그러나 대중문화의 SF적 상상력과 기술결정론적 미래학이 결합되어 그려지는 포스트휴먼 사회의 모습은 정당한 것일까? 포스트휴먼은 과연 사이보그 모델(기계적 보철화, 생명공학적 조작, 디지털 탈신체화)로 환원될 수 있을까? 시몽동의 기술-정치학은 도래 중에 있는 포스트휴먼 사회를 사유하는데 유용한 개념적 도구들과 새로운 청사진을 제시한다. 그에 따르면, 인간이 자신의 물리생물학적 조건을 넘어설 수 있는 가능성은, 생명체로서의 인간 개체 안에 내재하는 전(前)개체적 퍼텐셜의 존재와, 이 퍼텐셜 에너지를 개체초월적으로 집단화하여 현실화시킬 수 있는 기술적 대상들의 변환 역량에 있다. 포스트휴먼은 단지 기술의 효과에 불과한 것이 아니라 인간 안에 실재하는 ‘자연의 무게’와 더불어 발생한다. 기술은 결여된 인간을 강화하는 보철물이 아니라 인간의 잠재력을 현실화하는 매체로서 인간 사회의 새로운 구조화와 존재론적 도약을 가능하게 한다. 경제적 소외와 노동 문제로 환원될 수 없는 기술적 소외와 정보 소통의 문제, 인문교양으로 포괄할 수 없는 기술교육의 중요성, 기술적 활동을 통해 형성되는 개체초월적 집단성 등 시몽동의 통찰들은 포스트휴먼 사회로의 이행에서 주목해야할 기술-정치적 조건들을 보여준다. 인간의 사이보그화가 정당한지 비판하기 전에, 인간은 왜 ‘인간-기계 앙상블’의 형태로 변환하며 포스트휴먼 사회로 이행하고자 하는지 새로운 시각에서 접근할 필요가 있다. 나는 이 논문에서 시몽동의 기술-정치학이 어떻게 그 가능성을 제공하는지 밝혀보고자 한다.

단일 양자점으로부터 발생한 발광세기 변화에 대한 베이지안 다중 변화점 추정

김재희,김학준,Kima, Jaehee,Kimb, Hahkjoon 한국통계학회 2013 응용통계연구 Vol.26 No.4

단일 분자에서 발생한 발광의 세기 변화를 분석하는 문제는 단분자 분광학에서 반드시 필요하다. 본 연구에서는 카드뮴셀레나이드/황화아연의 중심-껍질 구조를 갖는 양자점에 대한 단분자 분광학 데이터에 대해 Poisson count data로서 베이지안 접근으로 모수에 대한 공액 감마분포와 변화점 개수에 대한 절단포아송 분포로 사전분포를 주고 다중변화점을 추정하였다. In the field of single-molecule spectroscopy, it is essential to analyze luminescence Intensity changes that result from a single molecule. With the CdSe/ZnS core-shell structured quantum dot photon emission data Bayesian multiple change-point estimation is done with the gamma prior for Poisson parameters and truncated Poisson distribution for the number of change-points.

Improving High-Voltage Stability of Nickel-Rich Layered Oxide Battery Cathode using Functional Additive

김재희,( Pham Quang Hieu ),황의형,권영길,이정규,송승완 한국공업화학회 2016 한국공업화학회 연구논문 초록집 Vol.2016 No.1

Three-components cathode active materials of Li(Ni_1-x-yCo_xMn_y)O₂ (NCM) are promising for high-energy density Li-ion batteries, and their capacity can increase by increasing the Ni content and the charge cut-off voltage (>4.2 V). However, their high voltage performance is difficult to achieve because of anodic decomposition of conventional electrolyte above 4.2 V vs. Li/Li⁺. At the high charge voltage condition, anodic instability of electrolyte and cathode-electrolyte interfacial reactions can result in a degradation of cathode material, leading to a rapid performance capacity fade. In order to overcome these issues, we have been searching for high-voltage electrolyte additives. Here we report a new electrolyte additive for charging the LiNi_0.6Co_0.2Mn_0.2O₂ cathode to 4.6 V. Studies of surface film formation would be discussed.

The purpose of this paper is to propose a flipped-learning method to make it easier for foreign students to write in Korean using intertextuality. For this purpose, I looked at how the concepts and features of intertextuality appear in various disciplines. Overall, intertextuality highlights the essence of text as multifaceted and text as a combination of different texts. In this sense, writing is a combination of various texts and is seen as discourse integration. Therefore, this paper introduces the citation which is a representative phenomenon of intertextuality in chapter 3-1 and presents educational methods to successfully apply it to flipped-learning after confirming its indicators. For example, in chapter 3-2, Greimas’ Isotopy was identified as a flipped-learning method. This paper highlights how one can activate various language and world knowledge of international Korean writing students in the field of education. In order to cope positively with changes in the educational environment, it can be said that flipped-learning can be applied to Korean text writing class. Learners who had encountered writing problems based on intertextuality will have the opportunity to expand their range of diverse personal experiences. Furthermore, these writing solutions can help to reduce the difficulties that various texts present.
