This paper compared and reviewed Tanizaki Junichiro literature and Lee Sang literature with a focus on three topics of ‘complex’, ‘succubism’, and ‘longing for modernization’. As esthetic writer and surreal psychological writer, writer from the ruling country and writer from the ruled country, writer who lived long while earning favorable reviews by the literary world and writer who died young while being despised by the public, two writers are seen as writers from the remote worlds not to be compared with each other at first glance. However, the above three patterns shown in the works of two writers can be said to be the commonalities of their literature. First, ‘complex’ resulted from the appearance inferiority in the case of Tanizaki and was caused by gynophobia in childhood in the case of Lee Sang. Second, ‘succubism’ was associated with two writers’ common experience of maternity love of in childhood, that is, an Oedipus complex. And finally, in the case of ‘longing for modernization’, it was found that an Edo native Tanizaki and Lee Sang reflected the desire for modernization in their works in westernized Tokyo at that time and Gyeongseong in 1930s being capitalized during the Japanese colonial period, respectively.

김상원,이정민,김종수,이상훈,Kim, Sang-Won,Lee, Jeong-Min,Kim, Chong-Soo,Lee, Sang-Hun 대한영상의학회 2002 대한영상의학회지 Vol.46 No.1

목적: 토끼의 정상 신실질에서 내부 냉각 단일형 침을 이용한 경피적 고주파열치료의 효용성 및 안정성을 평가하고,시술 후 추적 검사시 이중시기 나선식 CT에서 열치료의 형태 및 범위를 잘 반영할 수 있는지를 알아 보고자 하였다. 대상과 방법: 뉴질랜드 산 흰 토끼 26마리를 대상으로 초음파유도하에 경피적으로 17 G,1 cm의 노출 금속단을 가진 내부 냉각형 단일 침과 고주파 발생기를 사용하여 우측 신장의 하극부에 2분간의 열치료를 시행하였다.시술 후 조직의 파괴정도와 합병증의 발생 유무의 추적관찰을 위해서 시술직후와 시술후 24시간, 2일, 3일, 1주일, 2주일, 3주일, 4주일, 5주일, 6주일과 7주일후에 이중시기 나선식 CT를 시행하고 시기별로 급성기(시술직후 10마리), 아급성기{1일(3마리), 2일(3마리), 3일째(1마리): 8마리}, 만성기{1주일(4마리), 2주일(2마리), 4주일(1마리), 7주일(1마리): 8마리}로 분류하고 고주파열치료한 부위의 크기와 모양에 대하여 CT소견과 적출한 토끼의 신실질 병리소견을 비교 분석하였다. 결과: 시술직후 시행한 조영증강 이중시기 나선식 CT에서 고주파열치료가 시행된 부위는 모든 군에서 조영증강 되지 않는 저음영을 보였다.만성기에는 이중시기 나선식 CT에서 열치료 부위가 급성기나 아급성기에 비해 크기가 감소, 국소화되었으며, 조영전 CT에서 열치료병변 주위로 석회화가 보였고,조영후 고주파열치료된 병변 주위로 주변부 조영증강을 보였다. 병리학적으로 급성기에는 염증 세포의 침윤과 응고성 괴사를 보였으며, 만성기에 주변 정상 조직과 명확한 경계를 이루고 있었고 이와 함께 관상피 조직의 완전한 소멸과 사구체가 파괴된 소견이 동반되었다. 이중시기 나선식 CT와 적출 후 육안적으로 측정한 열치료병변의 최대 직경은 통계학적으로 유의한 차이가 없었다 (r=0.884,p >0.05). 결론: 내부 냉각 단일형 침을 사용한 고주파열치료는 안전하고 효과적인 국소 조직파괴방법이며, 조영증강 나선식 CT에서 조영 결손으로 보이는 병변의 크기는 열치료병변의 크기와 잘 연관되었다. 따라서, 고주파열치료는 작은 크기의 신장암의 치료에 있어서 덜 침습적이고 안전하며 효과적인 방법으로 사용될 수 있을 것이다. 또한, 열치료한 병변의 추적 관찰 시에 이중시기 나선식 CT가 유용한 방법으로 생각된다. Purpose: To assess the feasibility and safety of using a cooled-tip electrode to perform percutaneous radiofrequency ablation of kidney tissue in rabbits, and to evaluate the ability of CT to reveal the appearance and extent of tissue necrosis during follow-up after ablation. Materials and Methods: Using ultrasound guidance, a 17-G, cooled-tip electrode was inserted into the right lower portion of the kidney in 26 New Zealand White rabbits. Radiofrequency was applied for 2 mins, and biphasic helical CT scanning was used to assess tissue destruction and the presence or absence of complications immediately after the procedure and at 24 hrs, 2 and 3 days, and 1, 2, 3, 4, 5, 6 and 7 weeks. The study had three phases: acute [immediately killed : N=10]; subacute [killed at 24 hrs (n=3), 2 days (n=3), 3 days (n=1) : N=7]; chronic [killed at 1 week (n=4), 2 weeks (n=2), 4 weeks (n=1), 7 weeks (n=1) : N=8]. After the animals were killed, their kidneys were histopathologically examined and the radiologic and pathologic findings of lesion size and configuration were correlated. Results: In each instance, ultrasound-guided radiofrequency ablations of the lower pole of the kidney were technically successful. Contrast-enhanced biphasic helical CT revealed regions of hypoattenuation devoid of parenchymal enhancement, and these correlated closely with true pathologic lesion size (r=0.884; p>0.05). In subacute and chronic models, CT scanning revealed gradual spontaneous resorption of the ablated lesion and the presence of perilesional calcification. Histopathologically, in the acute phase the ablated lesions showed coagulative necrosis and infiltration of inflammatory cells, and in the chronic phase there was clear cut necrosis of glomeruli, tubules and renal interstitium, with diminishing inflammatory response and peripheral fibrotic tissue formation. Conclusion: Ultrasound-guided renal radiofrequency ablation is technically feasible and safe. In addition, the avascular lesion measured at contrast-enhanced helical CT closely correlated with the size of ablated tissue. Contrast-enhanced CT may therefore be used for serially monitoring the effect of radiofrequency ablation. In the future, RF ablation may offer an alternative treatment option for renal cancer.

김상원,Kim, Sang-Won 한국재료학회 2001 한국재료학회지 Vol.11 No.6

쐐기형 전극 사이에 열처리전 비정질 ($Fe_{1-x}$ $Co_{x}$ )$_{89}$ $Zr_{ 11}$ (x=0~1.0) 자성막이 증착된 MSAW 소자를 구성하고 외부 인가자기장에 의한 MSAW 속도변화율을 조사하였다. 그 결과 MSAW 속도변화율은 직류 인가자기장, 구동주파수, 자성막의 두께 및 조성에 민감하게 의존하였으며, 특히 구동주파수 및 자성막의 두께가 증가할수록 증가함을 확인하였다. 열처리전 시편에서 나타난 최대 속도변화율은 x=0.8에서 얻어진 0.062%였다. The velocity changes of magneto surface acoustic wave (MSAW) have been investigated in the MSAW devices composed of wedge type transducer and as-sputtered ($Fe_{1-x}$ $Co_{x}$ )$_{89}$ $Zr_{ 11}$ (x=0~1.0)amorphous films on glass substrates. The velocity changes of devices depended sensistively on exciting frequency of MSAW, applying the DC bias magnetic field. film thickness and film composition. Particularly. it was conformed that velocity changes increased with the increase of the exciting frequency of MSAW and the thickness of magnetic films. A device deposited x= 0.8 film along the MSAW propagation direction among the devices exhibited a large velocity change of 0.062% at 8.7 MHz for the applied field of 70 Oe.

The effect of field annealing on the velocity changes of magneto surface acoustic wave (MSAW) devices has been investigated for deposited $(Fe_{1-x}Co_x)_{89}Zr_{11}$ (x = 0~1.0) amorphous films. By means of two step field annealing at $195^{\circ}C$ for 10 minute in the magnetic field of 130 Oe, the MSAW device with x=0.4 film among the devices showed the superior velocity change of 0.1 %. This gigantic value was obtained in the DC bias field of 40 Oe at the exciting frequency of 8.7 MHz. It was confirmed that such behavior was due to the variation of differential permeability caused by an optimal stress within the magnetic film.

$(\textrm{Fe}_{1-x}\textrm{Co}_{x})_{89}\textrm{Zr}_{11}$ 비정질 자성박막의 자기특성(II)

김상원,Kim, Sang-Won 한국재료학회 1999 한국재료학회지 Vol.9 No.8

RF 스퍼터링법으로 제작한 비정질 (Fe(sub)1-xCo(sub)x)(sub)89Zr11 자성박막의 자기특성을 Co농도에 따라 조사하였다. 130 Oe의 인가자기장중 190~20$0^{\circ}C$ 에서 10분간 2단 열처리를 행하였을때, 시편중 x=0.4의 박막은 높은 자왜를 나타냄에도 불구하고 0.25 Oe의 낮은 보자력 H(sub)c과, 8.7 MHz, 10 mOe의 여기자기장에서 측정된 미분투자율 $\mu$(sub)d는 280 정도로 가장 양호한 값을 나타내었다. 이와 같은 거동은 박막내 최적의 압축응력상태에서 야기된 자기이방성의 변화에 기인한다. Magnetic properties of (Fe(sub)1-xCo(sub)x)(sub)89Zr11 amorphous films fabricated by RF sputtering method have been investigated as a function of Co content x. By means of two step field annealing at 190~20$0^{\circ}C$ for 10 minutes in the magnetic field of 130 Oe, the film with x=0.4 among the samples shows the superior soft magnetic properties in spite of showing the high magnetostriction. For example, the obtained properties of coercivity and differential permeability measured in an exciting field of 10 mOe at the frequency of 8.7 MHz are 0.25 Oe and 280, respectively. It is confirmed that such behavior is due to the variation of magnetic anisotropies caused by a optimal compressive stress within the film.

Purpose: To evaluate the prognostic factors that predict visual outcome after vitrectomy for lamellar macular hole using optical coherence tomography (OCT). Methods: This study included 26 eyes that underwent pars plana vitrectomy, epiretinal membrane removal, and internal limiting membrane peeling for lamellar macular hole. The maximum parafoveal thickness, maximum height and diameter of lamellar macular hole, maximum height and diameter of intraretinal splitting, thinnest foveal floor thickness, and inner segment/outer segment disruption length on preoperative OCT image were investigated for prognostic factors that predict visual outcome. Results: The mean follow-up period was 32.2 months and the mean best corrected visual acuity improved significantly after vitrectomy from log MAR 0.47 ± 0.32 to log MAR 0.23 ± 0.23. The postoperative visual acuity correlated significantly with preoperative visual acuity, thinnest foveal floor thickness and inner segment/outer segment disruption length, but not with maximum parafoveal thickness, maximum height and diameter of lamellar macular hole and maximum height and diameter of intraretinal splitting. Conclusions: The thinnest foveal floor thickness and inner segment/outer segment disruption length on preoperative OCT image were significant prognostic factors.J Korean Ophthalmol Soc 2014;55(12):1853-1859

방사선치료를 받는 말기암환자들을 대상으로 한 이완요법

김상원,전미선,김효신,Kim, Sang-Won,Chun, Mison,Kim, Hyo Shin 한국호스피스완화의료학회 2016 한국호스피스.완화의료학회지 Vol.19 No.3

방사선치료는 암과 관련된 증상을 완화시키는 목적으로 자주 사용되고 있다. 정확하고 안전한 방사선치료를 받기 위해서는 방사선이 나오는 동안 치료 테이블 위에 가만히 누워 있어야 한다. 그러나 일부 환자는 기질적인 문제 외에 심리적인 문제에서 기인한 증상으로 인해 가만히 누워 있지 못한다. 이 논문에서는 모의치료 단계 전부터 치료 테이블에 바로 누워 있지 못했지만 별 다른 장소에서의 교육 참여 없이 침상에서 쉽게 할 수 있는 이완요법을 배워 방사선치료 하는 동안 가만히 누워 있는 게 가능했던 두 명의 말기암환자 사례를 보고하고자 한다. Radiation therapy is an effective modality to alleviate cancer-related symptoms. To deliver radiation accurately, it is essential to secure stability of the treatment position in patients during each treatment time. However, some patients could be less cooperative due to their psychoemotional issues. We present two cases of terminal-stage cancer patients who were initially unable to lie still on the treatment table before simulation. A relaxation technique was taught to them on the bed, and they could relax and undergo radiation therapy with effective symptom relief.

핀테크 활성화 방안 연구: 미국, 중국, 한국의 규제 현황 중심으로

김상원,임석진,Kim, Sang-Won,Im, Seokjin 대한산업경영학회 2021 산업융합연구 Vol.19 No.4

IT를 융합한 새로운 형태의 금융 산업인 핀테크는 미국, 중국과 같은 선진국을 중심으로 비약적으로 발전하고 있다. 미국과 중국은 핀테크 산업의 발전과 규모의 확대를 위해 규제 완화를 통해 진입장벽을 낮췄으며, 하나의 예로 스타트업 기업들에게는 기존의 규제에 비해 더욱 완화된 또는 일정 기간 동안 규제를 적용하지 않는 방식의 negative 규제를 통해 다양한 아이디어들이 접목될 수 있도록 유도하였다. 미국과 중국은 기존에 있던 금융권의 규제들을 핀테크 산업에 적용하지 않아 핀테크 스타트업들이 보다 쉽게 성장할 수 있는 환경을 제공하였다. 현재 한국에서는 '삼성페이'와 '토스', '카카오페이' 등과 같이 핀테크 기술을 개발하여 활성화되고 있고, 그 규모도 확대되고 있다. 핀테크 발전을 위해 여러 가지 제도를 정비하고 규제를 도입하고 있지만 금융권과 각종 시장의 비우호적이고 비개방적인 규제 때문에 핀테크의 성장 속도가 느리다. 본 논문은 핀테크 선진국과 한국을 중심으로 핀테크 현황을 파악하고 핀테크 산업 발전을 저해하는 핀테크 관련 규제를 살펴본 후에, 핀테크 발전을 위한 해결방안으로서 positive 규제에서 negative 규제로, 사전 규제에서 사후 규제하는 등 금융 분야의 과도한 규제를 보다 유연하게 완화하는 방안을 제안한다. Fintech, a new form of financial industry that converges IT, is developing rapidly in developed countries such as the US and China. The U.S. and China lowered barriers to entry through deregulation to develop and expand the fintech industry, and, for example, encouraged startup companies to incorporate various ideas through negative regulations that are more relaxed or do not apply regulations for a certain period of time. The U.S. and China did not apply existing financial regulations to the fintech industry, providing an environment where fintech startups could grow more easily. Currently, in Korea, fintech technologies such as 'Samsung Pay', 'Toss' and 'Kakao Pay' have been developed and are being activated, and also their scale is expanding. Although various systems are being reorganized and regulated for the development of Fintech, Fintech's growth rate is slow due to unfriendly and unopened regulations in the financial sector and various markets. This paper examines the status of fintech, focusing on advanced fintech and Korea, and examines fintech-related regulations that hinder the development of the fintech industry. We propose a more flexible way of easing excessive regulation in the financial sector, such as post-regulation.

김상원,박재홍,안동섭,윤희성,Sang Won Kim,Jae Hong Park,Dong Seob Ahn,Hee Seong Yoon 대한안과학회 2014 대한안과학회지 Vol.55 No.12

Purpose: To evaluate the changes in each retinal layer thickness according to preoperative optical coherence tomography (OCT) patterns after idiopathic epiretinal membrane (ERM) removal and to investigate the correlation between retinal layer thickness and visual improvement. Methods: The medical records of 63 patients (63 eyes) who underwent vitrectomy with internal limiting membrane (ILM) peeling for idiopathic ERM and followed for more than 6 months were retrospectively reviewed. The OCT images of preoperative idiopathic ERM were classified into 3 patterns being flat, convex, and concave. Then, the changes of each retinal layer thickness were compared among OCT patterns and the correlations between retinal layer thickness and visual improvement were analyzed. Results: Improvement in visual acuity was measured in the following order: concave, flat, and convex patterns. The patients with the convex pattern only showed significant improvement of visual acuity. Ganglion cell layer plus inner plexiform layer (GCL + IPL), inner nuclear layer (INL), and outer plexiform layer (OPL) thicknesses were significantly larger in preoperative ERM patients than in normal controls in the following order: convex, concave, and flat patterns. Retinal layer thickness decreased significantly in GCL + IPL and INL after surgery in convex, flat, and concave patterns, in that order. Generally, preoperative retinal layer thickness and postoperative visual acuity were not correlated. However, improvement of visual acuity was significantly related to GCL + IPL and INL thicknesses in the convex pattern and IPL thickness in the flat pattern. Conclusions: In patients with idiopathic ERM, preoperative difference in each retinal layer thickness according to preoperative OCT patterns was observed. After ERM removal, reduction of each retinal layer thickness and specific retinal layer related to visual improvement was different according to preoperative OCT patterns.J Korean Ophthalmol Soc 2014;55(12):1843-1852
