The study analyzes a personal history of violence and loss in Incendies, focusing on trauma. The film portrays Jeanne and Simon’s journey to trace the past of their mother Nawal, which oscillated between Christianity and Islam, student and terrorist, mother and prisoner. This research pays attention to the narrative of the film based on the myth of Oedipus, where the mechanism of trauma is related to loss and separation. The history of the Marwan family, which borrows the structure of the aforementioned Greek tragedy but applies a twist at the climax, depicts the mourning and melancholy of loss and suggests the attributes of trauma. In addition, Nawal’s narrative, which recounts the memories and emotions of wounds, suggests working through such wounds and facing the loss following trauma.

중립성 가설에 관한 소고

이일수,최종수 군산대학교 현대이념연구소 1996 現代理念硏究 Vol.11 No.-

This study considers the concept of the Debt Neutrality Hypothesis(DNH) From theoretical and empirical perspectives. The impact of government variables on private-sector consumption is a key issue in assessing the implications of fiscal and monetary policy on the real side of the economy. In fact, there are sharp controversies on this topic, most of which center around the DNH. This so called Neutrality Hypothesis states that, for a given expenditure path, substitution of debt for taxes does not affect private-sector wealth, consumption decisions and consequently savings decisions. But others believe that the DNH greatly exaggerates the public's perception of and response to the future tax obligations implied by existing government debt. This paper examines 2 theoretical models illustrating the implications of the DNH, investigates effects of relaxing the basic assumptions, and formally derives policy implications of the DNH from the results. On balence, we prove that an answer to whether the DNH is a good approximation to reality has to come from empirical study and that the debate about the theoretical and empirical validity of the DNH is far from resolved, as the analysis tries to demonstrate.

식도암에서 전이된 피부 전이암 2 예

이일수,정찬우,민형근,신장현 대한피부과학회 2000 大韓皮膚科學會誌 Vol.38 No.7

We report two cases of cutaneous metastases originating from esophageal carcinoma. Case 1, about 0.5cm sized brownish round keratotic papule was detected 1 month ago on the left fifth finger tip in a 70-year-old man. Case 2, about 1.5×1.2cm sized ivory oval flat topped elevated nodule was detected 1 month ago on the lower lip in a 60-year-old man. Histologic examination of case 1 showed that dilated lymphatics contained tumor nests, some of which showed central necrosis. Case 2 showed tumor cell infiltration from upper dermis to mid dermis. Regardless of chemotherapy, both patients died after two and three months from the appearance of cutaneous lesions respectively.

Superparamagnetic Transition in Ultrasmal Superparamagnetic Iron Oxide Nanoparticles

이일수 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.54 No.4

We report the superparamagnetic transition for USPIO (ultrasmall superparamagnetic iron oxide) nanoparticies with an average diameter of 7 nm. This was observed in the zero field cooled/field cooled (ZFC/FC) and hysteresis curves. The field dependence of the blocking temperature followed the Almeida- Thouless linear behavior of a spin glass system below a crossover field of = 300 Oe. However, a more rapid change in the blocking temperature with increasing applied field was observed above , which can be qualitatively explained by the dipole-dipole interactions in the powder sample. The temperature dependence of the coercivity followed a power law of in the intermediate temperature range.

Chitosan-coated Ferrite (Fe3O4) Nanoparticles as a T2 Contrast Agent for Magnetic Resonance Imaging

이일수,Sungwook Hong,장용민 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.56 No.3

Iron oxide (Fe3O4) nanoparticles coated with biocompatible chitosan were synthesized for use as an MRI (magnetic resonance imaging) contrast agent. The coating was performed simultaneously with the synthesis of the ferrite nanoparticles. A dynamic light-scattering spectrometer (DLS)and a transmission electron microscope (TEM) were used to measure the average diameter of the coated nanoparticles, which was 67.0 nm. Fourier transform infrared (FT-IR) measurements showed strong bonding of the chitosan molecules to the surfaces of the ferrite nanoparticles. The spin-lattice (T1) and the spin-spin (T2) relaxation times of the nuclear spins (hydrogen protons) in aqueous solutions of various concentrations of coated ferrite nanoparticles were determined using a nuclear magnetic resonance (NMR) spectrometer. Using these data, we found that the T1 and the T2 relaxivities of the nuclear spins in aqueous solutions of ferrite nanoparticles were 0.00291 and 0.0691 ppm−1sec−1, respectively. In particular, the value of the T2 relaxivity was much larger than that of the commercial contrast agent GD-DTPA (gadolinium diethylenetriamine penta-acetic acid). A 31.7% intensity loss in the T2 image of a rabbit liver was observed after injecting the aqueous solution of coated nanoparticles into the rabbit, which shows that our coated ferrite nanoparticles can be used as a T2 MRI contrast agent.

『위대한 개츠비』와 자기결정의 윤리

이일수 한국외국어대학교 영미연구소 2019 영미연구 Vol.45 No.-

Recent studies on The Great Gatsby have shown the tendency to regard the work as a mourning narrative which tries to reclaim the lost national manhood in the American modernity. They agreed that the aggressive manhood of the 19th century for the fulfillment of the frontier complemented by compassion for one’s family and neighbors disappeared with the rise of the ruthless, competitive manhood with the capacity of accumulating the modern capital of the early 20th century. This paper critically examines these mourning discourses because they do not seem to provide an appropriate explanation for Gatsby’s capitalist aspects who wanted to secure Daisy, the expressive iconography of the early modern consumers of the mass production system in the twenties. He was doomed to fail since he, as an early capitalist aspirant, could not comprehend the arbritrary, unpredictable unworthiness of the consumer aspects of hers. Just as Fitzgerald called forth, in his autobiographical essays, The Jazz Age, the true intelligence with self-determination to make a change out of the hopeless present, so in The Great Gatsby, the author represented the ethics of self-determination with which Gatsby tried to realize the “yet to come” future, significantly, with his sacrifice to the determined cause. 『위대한 개츠비』에 대한 최근 연구 경향은 이 작품을 미국의 근대적 남성성 상실을 애도하는 서사로 읽는 것이 지배적이다. 변경을 개척한 진취성과 가족과 이웃을 돌보는 자상함을 갖춘 19세기 전인적 남성성이 종말을 고하고 맹렬한 자본 증식의 경쟁을 감당할 무자비한 경쟁적 남성성이 부상함으로써 그 상실된 과거 남성성에 대한 애도가 이 작품에 담겨있다는 것이다. 이 논문은 그러한 애도 서사적 견지를 비판적으로 검토한다. 개츠비의 물질적 성공 추구에 내재된 자본가적 욕망을 과거의 온전한 남성성으로 설명하기 어렵기 때문이다. 무산자의 익명성에서 탈피하여 자본의 위력에 의해 데이지를 되찾으려 한 그의 욕망은 20세기 초 대량생산 대량소비 시스템이 낳은 자본가적 욕망이다. 그러나 화자 닉이 직관적으로 포착한 대로, 개츠비에게는 임의적이고 예측이 불가한 신흥 소비권력에 굴복하는 초기 자본가적 측면과, 그 권력의 임의성에 굴하지 않고 무가치한 현실을 변화시키려는 자기희생의 결단을 내린 윤리적 개인의 측면이 공존한다. 작가는 그의 에세이집 『재즈 시대』에서 절망적 현실을 변화시킬 자기결정의 지성을 요청했다. 이 지성은 삶의 상충하는 이념들을 관용적 태도로 수용하면서도 현실변화에 대한 명확한 자기결단을 내릴 수 있는 힘이다. 『위대한 개츠비』는 자본을 축적하여 “아직 오지 않은 미래”의 존재 가치를 실현하려 한 개츠비의 실패를 다루지만, 그 실패가 절망적 현재를 변화시키려는 희생과 헌신의 자기결정의 윤리를 체현한 것임을 독자에게 일깨운다.

습식 Batch Process에 의한 ZnO미분말 합성

이일수,조성백,신건철 한국결정성장학회 1991 韓國結晶成長學會誌 Vol.1 No.1

출발용액으로 $ZnCl_2$와 Hexamethylenetetramine 용액을 사용한 Batch process를 이용하여 ZnO 미분말을 합성 하였다. 합성된 입자의 형태는 $ZnCl_2$용액의 농도가 $0.1mol/\ell$와 $0.05mol/\ell$에서 봉형이 얻어졌고 $0.01mol/\ell$판형의 분말이 얻어졌다. Hexamethylenetetramine은 늦은 속도로 가해, $ZnCl_2$의 농도가 0.05mol/l일 때 핵 생성제로 $NH_4$OH를 첨가하였다. 이때, 얻어진 분말의 평균 입자크기는 약 $0.4\mu\textrm{m}$였고 형태는 구형이었다. $500^{\circ}C$에서 1시간 하소한 후, 입자에 일부 존재하던 유기물은 모두 제거되었다. 이때, 입자의 전체적인 형태에 있어서는 큰 변화가 없었으나 크기는 약간의 감소가 일어났다. ZnO fine powder was prepared by the batch precipitation process using $ZnCl_2$ and hexamethylenetetramine solution as a mother solution. When the concentrations of $ZnCl_2$solution were $0.1mol/\ell$ and 0.05mol/-, the particles of rod shape were obtained when the conentration of $ZnCl_2$solution was $0.01mol/\ell$, the particle of plate shape was obtained. When the hexamethylenetetramine as a precipitants was used, pH was raised slow during a few minute be-cause of slow hydrolysis rate of hexamethylenetetramine. For rapid raising of pH during initial reac-tion time, $NH_4$OH was added as nucleant. When $NH_4$OH as a nucleant was added, obtained particle was shape of granular and the mean particle size was $0.41\mu\textrm{m}$. After calcination at $500^{\circ}C$ during 1hour, all of remained organic phase was removed but the shape of particles was not changed. But pa-rticles were slightly shrunk in comparision with before calcined particles.
