윤대녕 소설에 나타난 환영적 메커니즘

최영자 ( Young Ja Choi ) 한국문학연구학회 2011 현대문학의 연구 Vol.0 No.44

<천지간>의 화자는 외숙모의 부음을 접하면서 흰색의 이미지를 환유적으로 연상한다. 이후 화자는 상가로 가던 중 불현듯 시야에 들어온 ``그 여자``를 따라가는데, 이는 결과적으로 ``그 여자``의 잉태된 아이를 구하는 것이 된다. 이때 ``나``는 ``그 여자``의 응시 속에 ``사로잡힌`` 사물화된 어떤 형태를 갖는다. 윤대녕 소설에서 이 같은 환영적 메커니즘은 빈번하게 나타난다. <소는 여관으로 들어오다>에서 화자는 비구니 ``금영``에게서 ``밀짚모자 여자``를 보고 또 ``환생한 생모``를 본다. 또 <제비를 기르다>에서 화자는 현재의 ``문희``에게서 과거 ``작부 문희``의 모습을 떠올린다. <은어낚시 통신>은 어린 날 아버지와 왕피천에서 낚시를 했던 경험이 있는 화자가 우연한 모임에서 만난 ``그녀``도 같은 시기에 비슷한 장소에서 은어낚시를 즐겼다는 것을 알게 되는 내용이다. 이를 통해 그는 어디선가 서로 비껴갔을 지도 모른다는 생각을 하면서, 불현듯 우리 모두는 자신의 근원지로 돌아가기 위해 우연을 가장한 필연을 반복하고 있는 것은 아닌지 생각한다. 봄이 되면 거센 물살을 거스르며 회귀하는 ``은어``는 물의 그물망을 통해 펼쳐지는 사물화된 환영을 통해 자신을 실존을 죽음으로 증명한다. 윤대녕 소설의 미학은 이 같은 환영적 메커니즘을 통해 일상을 낯설게 인식하게 하는 기교에 있다. The purpose of this study is to reveal the structural mechanism in novels written by Yoon Dea Nyeong. In Cheon-ji-gan, the narrator associates the image of ``white`` in metonymy, when hearing of the ``death`` of his maternal uncle`s wife. On the way to the family in mourning, he happened to follow ``a woman`` who came into his sight, and he would later figure out that he saved the new life inside her. In this context, ``I`` exist in a certain reification form ``captivated`` by ``her`` gaze. Illusionary mechanism frequently appears in Yoon Dea Nyeong`s novels. In Cowcomesintoinn, the narrator sees ``a woman in a straw hat`` and ``reincarnated birth mother`` in Buddhist nun ``Keum Young``. In Raisinga swallow, the narrator recalls ``Mun Hee`` in the past, who were a prostitute, from present ``Mun Hee``. In Sweetfish-fishingreport, In the memories of childhood, ``I`` used to fish with my father in some places such as ``Wangpicheon``. One day, he came to know that ``the woman``, one of his acquaintances from ``Sweetfish Fishing Report``, also enjoyed fishing sweetfishes in the same place and period. ``Sweetfishes`` return to their birthplace in spring season to prove their existence through unconscious illusion spreaded over the water grid. In this regard, Yoon Dae Nyeong utilizes illusion to defamiliarize the reader`s sense of dailiness. From an aesthetic point of view, his novel is the quintessence of defamiliarization by means of the reification of daily life.

Purpose: Purposes of this study were to understand the current trends on complementary therapy in relieving chemotherapy-induced nausea and vomiting and to suggest the future research direction. Method: Subjects were selected on CINAHL, MEDLINE, Korean Academy Data Base from 1980 to 2001 which used nausea, vomiting, chemotherapy and complementary therapy as key words in experimental studies. Eight korean articles and twenty-one international articles were analyzed in terms of general characteristics, research methods, and types of complementary therapy. Data were analyzed by using descriptive statistical methods. Result: Since 2000, researchers have more actively used complementary therapy. In subject characteristics, mean age was 35.5 years old, 45% of the researchers were performed with high level of incidence of chemotherapy induced vomiting, 14% of them set limit of consecutive cycle during research, and 65% of them did not comment the selecting criteria of sample. About 60% of them were designed post-test only control group: 35% used INV by Rhodes, 31% used Likert scale, and 24% used VAS for dependent variable. Muscle relaxation therapy was mostly applied for relief of nausea and vomiting. Conclusion: Further studies will be needed to control extrinsic variables affecting nausea and vomiting in research design and to accumulate evidence with studies applying various complementary therapies.

주용진,최성문,최영자,성호석 ( Yoing Jin Joo,Sung Moon Choi,Young Ja Choi,Ho Suk Sung ) 대한피부과학회 1990 대한피부과학회지 Vol.28 No.5

A Case of Ehlers-Danlos syndrome Yoing Jin Joo, M.D., Sung Moon Choi, M.D., Young Ja Choi*, M.D., Ho Suk Sung, M.D. Department of Dermatology, Clooego of Medicine, Inje University, Pusan, Korea We presented a case of Ehlers-Danlos syndrome in a 25-year old female, who had hyperextensibility of skin, skin fragility, cigarette paper-like atrophic scar, joint hyperextensibility and skeletal abnormality of scoliosis since birth. There was no family history. Microscopic and electron microscopic examinations of the skin biopsy specimens from normal appearing skin on the forearm and the site of subcutaneous nodule was compatible with finding of Ehlers-Danlos syndrome. Although the manifestations of this case including marked extensibility of skin, joint, skin fraility and atrophic scar might be in accord with type Ⅰ(gravis) Ehlers-Danlos syndrome, skeletal abnormality of scoliosis did not correspond to this type, but to type Ⅳ(hydroxylysine deficient) Ehlers-Danlos syndrome. We consider this case as a type Ⅳ Ehlers-Danlos syndrome.

강유전체 질소화합물 thiourea [SC(NH₂)₂]분말시료의 ??plused NQR 실험을 77K 에서 실행하여 공명진동수와 핵사중극 결합상수, 비대칭인자, 완화시간등을 측정했으며, 4개의 공명선이 관측되었다. 결정내에는 주위 환경이 다른 두 종류의 질소 N₁,N₂가 존재함을 알 수 있었다. N₁에 관한 공명진동수는 ??(1)=2.6487㎒, ??(1)=2.032㎒, N₂에 대하여는 ??(2)=3.1852㎑, ??(2)=2.0183㎒이고, 공명선폭은 ??(1)=2.6752㎑, ??(1)=3.1852㎑, ??(2)=3.2618㎑, ??(2)=3.5448㎑ 임을 보였다. 한편 e²qQ/h의 값은 ν(1)에서 3.1205㎒, η는 0.3953이었으며, ν(2)에서는 3.0279㎒, 0.3939이었다. 이는 이미 보고된 결과와 일치하였다. 그리고, FID(Free Induction Decay)와 spin-echo실험을 통하여 얻은 스핀-격자 완화시간 T₁은 ??(1)에서 7.143 s, ??(2)에서 5.88 s이었으며, 스핀-스핀 완화시간 T₂는 ??(1)에서 25㎳, ??(2)에서 33.3㎳, ??(2)에서 33.3㎳의 값을 얻었다. We have measured ??N NQR frequencies, nuclear quadroupole coupling constants, asymmetric parameters and relaxation times in ferroelectric nitrogen thiourea [SC(NH2)2] at 77K, and four NQR resonance lines were observed. The results of measurements show that there are two kinds of nitrogen site, N1 and N2, with different environments in the crystal. The resonance frequencies were found to be ν+(l)=2.64 87MHz, ν_(1)=2.032 MHz for N1 and ν+(2)=2.6285MHz, ν_(2) =2.0183MHz for N2 respectively. The corresponding linewidths were ν+(1)= 2.6752kHz, Δν_(l) =3.1852kHz, ν+(2) =3.2618kHz and Δν_(2) =3.5448kHz, respectively. For N1, e2Q/h is 3.1205 MHz and η is 0.3953, and for N2, these are 3.0979MHz and 0.3939. These results are in agreement with those reported previously. The spin-lattice relaxation time (Ti) and the spin-spin relaxation time (T2) by FID and spin-echo experiments are as follows : T1(ν+(1)) is 7.143 s and T1(ν+(2)) is 5.88 s. T2(ν+(1)) is 25 ms, T2(ν_(1)) is 25 ms, T2(ν+(2)) is 33.3 ms and T2(ν_(2)) is 33.3 ms.

최자영,권영춘,여상학,정동근 성균관대학교 기초과학연구소 1999 論文集 Vol.50 No.-

In this work, we report on the investigation of the properties of cyclohexane-based plasma polymers (CHexPP) as functions of the deposition pressure and the plasma power. As the deposition pressure was decreased from 2 torr to 0.2 ton with a fixed plasma power of 60W, k value of the CHexPP thin film increased from 2.42 to 3.24. CHexPP thin films deposited at lower deposition pressure showed very good thermal stability, even the one deposited at 0.2 torn was stable up to 400℃. As the plasma power was increased from 10W to 90W with a fixed deposition pressure of 0.2 ton, k value increased from 2.61 to 3.39. The CHexPP thin film deposited at 90W were stable up to 450℃. All the deposited films were insulating. Under applied fields less than 1 MV/cm, leakage current densities were less than 10^-7 A/㎠.

최호춘,김강윤,안선희,이영자,정규철 한국산업위생학회 2001 한국산업보건학회지 Vol.11 No.2

This study was performed to measure airborne dimethyl-formamide(DMF), methyl ethyl ketone(MEK) and toluene and their urinary metabolites concentrations and to determine the relationship between airborne and urinary concentration. Air-borne samples and their urinary metabolites were measured 98male workers who work for 8 synthetic leather factories in a portion of Kyoung-in area. Urine samples were collected at end-of-shift to estimate the exposure levels. 1. The concentration of airborne DMF by process was 8.81 ppm for wet-mixing, 15.05 ppm for wet-coating, 6.03 ppm for dry-mixing, 5.58 ppm for dry-coating, 5.37 ppm for printing, and 9.03 ppm for total. There was statistically significant difference by process. Urinary NMF concentrations of wet-mixing, Wet-coasting, Dry-mixing, dry-coating and printing were 90.55㎎/, 79.80㎎/ℓ, 39.86㎎/ℓ, 25.23㎎/ℓ, and 38.15㎎/ℓ, respec-tively, and total geometric mean was 56.24㎎/ℓ. There was statistically significant difference by process. 2. The concentration of airborne MEK by process was 1.89 ppm for wet-mixing, 1.96 ppm for wet-coating, 10.33 ppm for dry-mixing, 29.24 ppm for dry-coating, 14.98 ppm for printing, and 4.87 ppm for total. There was statistically significant difference by process. Urinary MEK concentrations of wet-mxing, wet-coating, dry-mixing, dry-coating and printing were 0.93㎎/ℓ, 0.70㎎/ℓ, 3.29㎎/ℓ, 3.29㎎/ℓ, and 1.06㎎/ℓ, res-pectively, and total geometric mean was 1.25㎎/ℓ, There was statistically significant difference by process. Urinary MEK 3.The concentration of airborne toluene by process was 0.35ppm for wet-mixing, 0.42ppm for wet-coating, 2.95ppm for dry-mixing, 11.67ppm for dry-coating, 4.88ppm for printing, 1.24ppm for total. There was statistically significant difference by process. Urinary hippuric acid concentrations of wet-mixing, wet-coating, dry-mixing, dry-coating and printing were 0.24g/g creatinine, 0.21g/g creatinine, 0.34g/g creatinine, 0.52g/g cre-atinine, and 0.29g/g creatinine, respctively and total geometric mean was 0.28g/g creatinine. There was statistically signifi-cant difference by process. 4. No. of exceeded KPEL was 40 workers(40.8%) for DMF(10ppm), 1 worker(1.0%) for MEK(200ppm), and no worker for toluene(100ppm). No. of exceeded KBEI was 62 workers(63.3%) for urinary NMF(40㎎/ℓ), 29 workers (29.6%) for uri-nary MEK, 1 worker(1.0%) for urinary hippuric acid. 5. The regression equations were Log(MMF)=0.4094* Log(DMF)+1.3587(r=0.4516) for DMF, Log(MEKU)=0.1859* Log(MEK)-0.0324(r=0.3303) for MEK, Log(HA)=0.2106* Log(Toluene)-0.5685 (r=4497) for toluene. Synthetic leather factory workers expose to 3 kinds of organic solvents which are DMF, MEK and toluene. Their Uri-nary NMF and MEK levels were higher than their concentration levels through respiratory. It seems that the urinary levels were affected skin absorption for working habit and alcohol intake.
