Acupuncture has been used for treatment of numerous diseases, especially for pain control in the oriental culture. However, the mechanism of pain control by acupuncture was not clear so far. The present study was examined that the effects of electro-acupuncture (EA) applied to the acu-point of extra-segmental area on modulation of formalin induced pain in Sprague - Dawley rats. In order to apply EA to acu-points in the plantar area of right fore paws, a pair of teflon - coated stainless steel wires were implanted in HT 7 (shin-mun) and PC 7 (dae-neong) 5 days before behavioral test. A behavioral test was performed by means of video camera after injection of 5% formalin ($50{\mu}l$) into the lateral plantar region of left hind paw. EA was delivered by a constant current stimulator at 4~5 mA, 2 ms, and 10 Hz for 30 min. The electromyographic activities were recorded in the biceps femoris muscle under chloral hydrate anesthesia. Test stimuli with 1~9mA were applied to the sural nerve territory including the medial portion of the 4th toe and the lateral portion of the 5th toe. Behavioral responses including favoring, flinching and bitting were occured in the biphasic pattern, such as the lst phase (0~5 min) and the 2nd phase (20~45 min) after formalin injection. However, EA (4~5 mA, 2 ms, 10 Hz) significantly inhibited Che behavioral responses. EMG activities of flexor reflex had a latency of 100~300 ms and thresholds of test stimuli for EMG were 4~5 mA in normal rats. Injection of formalin decreased threshold of test stimuli and increased EMG activities for 2hrs after injection. However, EA significantly inhibited EMG activities of flexor reflex increased by formalin and recovered EMG evoked thresholds. These results suggest that contralateral extra-segmental EA inhibits the first and second phases of formalin induced pain but their mechanism be needed to examine additionally.

본 연구는 국내에서 다량 취급되고 있는 암모니아 및 톨루엔을 흄 상태로 노출시킨 후 흡수/흡착방법을 달리한 이동형 스크러버를 이용해 각 유해화학물질의 제거효율을 비교 분석하였다. 이동형 스크러버는 기 개발된 장치를 개선하여 와류세정에 의한 흡수, 유입풍속 조절의 장점을 살리고, 활성탄 및 카본필터를 통한 기체상 유해화학물질의 흡착방법 도입을 통해 단점을 보완하였다. 개선된 장치는 기초성능평가를 통해 적정 제어풍속이 검증되었고, 5% 암모니아수 용액을 흄 상태로 노출시켜 후드 흡입부, 송풍기 배출부 및 세정기가 정상 작동함을 확인하였다. 흡수/흡착방법에 따른 암모니아 제거효율은 90분 경과 후 C≥PCA>SWA 순으로 가장 우수한 SWA 군의 노출 농도별 제거 효율은 시간이 경과할수록 노출 농도와 무관하게 배출 농도는 증가되었고, 세정액의 pH는 산성에서 염기성으로 변화되었다. 또한, 시간 경과에 따른 노출 농도 별 세정액의 pH 변화와 배출구 농도 변화 사이에 0.9429~0.9491 수준의 정의 상관관계를 나타내었다. 흡착방법에 따른 톨루엔의 제거 효율은 초기 10분 경과 후 배출구농도에서 C>CMA≥GCA 순을 나타내다 90분 경과까지 일정한 농도로 유지되었다. 가장 우수한 GCA 군의 노출 농도 별 제거 효율은 초기 10분 경과 시 노출 농도에 비례하여 배출 농도가 높은 경향이었다. 이와 같은 결과를 통해 개선된 이동형 스크러버는 중화반응에 의해 산성 또는 염기성 유해화학물질의 제거뿐 아니라, 활성탄 등의 흡착기능 개선을 통해 VOCs 제거에도 효과적이었다. 하지만, 실제 현장에서 활용이 가능하도록 세정액 pH를 지속적으로 유지하여 연속적으로 흡수 제거할 수 있는 방법과 노출되는 화학물질 농도와 흡착제의 관계에서 파괴점, 포화점, 흡착속도 등의 물리적인 요소가 추가적인 연구를 통해 도출되어야 할 것이다. BACKGROUND: The mobile vortex wet scrubber was developed to remove the harmful chemicals from accidental releases. However, there was a disadvantage that it was limitedly used for volatile organic compounds (VOCs) such as toluene according to the physicochemical properties. This study compared the removal efficiencies of an improved mobile scrubber on toluene and ammonia by applying diverse adsorption and absorption methods. METHODS AND RESULTS: The removal efficiencies on harmful chemicals were examined using various adsorption and absorption methods of water vortex process (C), phosphoric acid-impregnated activated carbon adsorption (PCA), pH-controlled water (pH 2.5) vortex process absorption with sulfuric acid (SWA) after ammonia exposure, granular activated carbon adsorption (GCA), and activated carbon mat adsorption (CMA) after toluene exposure. As a result, the best removal efficiency was shown in the SWA for ammonia and GCA for toluene. Also, the SWA and GCA methods were compared with different concentration levels. In the case of ammonia exposure (5, 10 and 25%), there was no difference by concentration levels, and the concentration in the outlet gradually increased, with pH change from acid to base. In the case of toluene exposure (50, 75 and 100%), the outlet concentration was higher relative to the exposure concentration in the initial 10 min, but the outlet concentration was remained steady after 10 min. CONCLUSION: The newly improved mobile scrubber was also effective in removing VOCs through adsorption techniques (activated carbon, activated carbon fiber, carbon mat filter etc.), as well as removing acid-base harmful chemicals by neutralization reaction.

흰쥐의 내측 전정신경핵 흥분성에 대한 전침자극의 효과

김재효 ( Jae Hyo Kim ),이성호 ( Sung Ho Lee ),손인철 ( In Chul Sohn ),김영선 ( Young Sun Kim ),김민선 ( Min Sun Kim ) 대한경락경혈학회 2009 Korean Journal of Acupuncture Vol.26 No.3

Objectives: The vestibular system detects head movement and serve to regulate and maintain the equilibrium and orientation of the body. It is known that the vestibular imbalance leads to vestibular symptoms such as nausea, vomiting, vertigo and postural disturbance. The objectives of the present study were to examine a modification of the dynamic activities of medial vestibular nucleus (MVN) neurons following electroacupuncture (EA) of GB43 (Hyepgye). Methods: In Sprague-Dawley rats weighing 250~300g, dynamic responses induced by sinusoidal whole body rotation about vertical axis at 0.2 ㎐were observed in MVN of rats during EA of GB43 (Hyepgye) with 0.2 ms, 40 Hz and 600±200 ㎂. Also, expression of cFos protein was observed 2 hours after EA for 30 mins. Results: In dynamic response of vestibular neuron, the excitatory or inhibitory responses of gain were predominant in the ipsilateral MVN neurons during EA but not predominant in the contralateral MVN. Most neurons showing decreased gain were classified to inhibitory responses of spontaneous firing discharge during EA and ones showing increased gain were classified to excitatory response of spontaneous firing discharge during EA. Also, EA of the left GB43 (Hyepgye) for 30 mins produced the expression of cFos protein in MVN, inferior olive (IO) and solitary tract nuclei (SOL). Spatial expressions of cFos protein were predominant in the contralateral MVN, ipsilateral IO and bilateral SOL. Conclusion: These results suggest that the excitability of MVN neurons was influenced by EA of GB43 (Hyepgye) and EA may be related to the convergence on MVN.

소아에서 시행한 방광요도 조영술 이후 발생한 합병증에 대한 고찰

김민선,이승현,김정화,장영범,이대열,Kim, Min-Sun,Lee, Seung-Hyun,Kim, Jeong-Hwa,Chang, Young-Bum,Lee, Dae-Yeol 대한소아신장학회 2007 Childhood kidney diseases Vol.11 No.1

목적 : 요로 감염이나 선천성 수신증, 기타 선천성 신장 질환이 있을 때 방광 요관 역류가 동반되는 수가 많다. 방광요도 조영 검사는 이를 확인하는 비교적 간단한 검사이나 검사 후 여러 불편감이나 합병증이 있어 환아들이 기피하는 검사 중의 하나이기도 하다. 따라서 저자들은 방광요도 조영 검사 후에 발생한 합병 증상의 종류와 빈도, 증상 지속 기간 등을 알아보기 위해 이 연구를 시행하였다. 방법 : 2005년 10월에서부터 2006년 9월까지 전북대학교병원 소아과에 내원하여 배뇨성 방광요도 조영술 및 방사선핵종 방광 조영술을 시행하였던 환아를 대상으로 전향적 조사를 하였다. 검사를 시행하게 된 원인 질환과 검사 방법, 검사 성공 여부, 최종 진단을 확인하였고, 1주일 경과 후 전화를 통한 설문 청취 방법으로 합병 증상의 종류와 지속 기간을 조사하였다. 결과 : 대상 환아 270명 중 1례에서는 도뇨관 삽입 실패로 검사를 시행하지 못하여 성공률은 99.6% 이었고, 검사를 받은 평균 연령은 $16.5{\pm}29.9$개월이었으며, 이 중 남아는 190명(70.6%), 여아는 79명(29.4%)이었다. 검사를 시행하게 된 원인 질환으로는 요로 감염 168명, 수신증 55명, 방광요관 역류로 인한 추적 검사 39명, 신무발육증 3명, 다발성 낭성 이형성 신 3명, 중복 요관 1명이었다. 269명의 환아 중 검사 시행 후 88명 (32.7%)에서 검사와 관련된 합병증을 보였고 증상 지속기간은 $1.4{\pm}0.7$일 이었다. 이 중 배뇨곤란의 경우가 49명(55.7%)으로 가장 많았고, 보챔 36명, 발열 11명, 빈뇨 8명, 육안적 혈뇨 4명 순이었다. 이외에도 심한 합병증인 요로 감염과 방광 천공도 각각 1명에서 발생하였다. 이러한 합병 증상은 연령이 증가하면서 호소 빈도가 증가하였고 (P<0.05), 검사 당시의 항생제 사용이 이러한 합병 증상의 빈도를 감소시키지는 않았다. 결론 : 소아에서 방광 요도술 검사는 간편하고 비교적 안전한 검사법으로 알려져 있으나 본 연구에서는 대상 환아의 약 1/3에서 합병 증상이 발생하였고 요로 감염과 방광 천자 같은 심한 합병증도 발생하였다. 따라서 방광요도 조영술 검사 시 이러한 합병 증상을 예방하기 위한 세심한 주의와 심각한 합병증이 발생한 경우에 신속한 처치가 필요할 것으로 보인다. 그러나 예방적 항생제 요법은 검사 후 발생하는 요로 감염이나 여러 증상을 줄이지는 못하여 이에 대한 더 많은 연구가 필요할 것으로 사료된다. Purpose : Voiding cystourethrography(VCUG) is a commonly performed diagnostic procedure in children with urinary tract infections. Recently, with the widespread use of prenatal ultrasonography, VCUG is performed as part of the postnatal radiological evaluation of asymptomatic infants with prenatally detected hydronephrosis. The procedure is relatively simple but it involves discomfort and some complications. We studied post procedural symptoms and complications in children who underwent VCUG. Methods : This study reviewed 259 patients who underwent VCUG in our hospital between October 2005 and September 2006. We did a chart review and a telephone interview with the patients' parents about symptoms and complications associated with VCUG. Results : Among 269 children, 217 patients(80.7%) were under 2 years of age and 5 patients (1.9%) were over 8 years of age. Their mean age was $13.1{\pm}22.9$ months. After VCUG, dysuria was found in 49 patients presented with dysuria, and irritability in 36 patients with irritability. Other complications were hematuria, fever, frequency, bladder rupture and urinary tract infection. Mean symptoms duration was $1.4{\pm}0.7$ days. There was no significant relationship between prophylactic antibiotics use and complication rate associated with VCUG. Conclusion : Our study demonstrated that 32.7% of patients showed complications including bladder rupture and urinary tract infection after VCUG. We also found that prophylactic antibiotics use did not prevent urinary tract infection nor decrease the rate of complications associated with VCUG. Therefore, we suggest that the procedure must be done carefully and aseptically, and we should closely observe the children who undergo VCUG for development of possible complications.

Permanent neonatal diabetes(PND) is a rare form of diabetes characterized by insulin-requiring hyperglycemia that is diagnosed within the first 3 months of life. In most cases, the causes are not known. Recently, mutations in the gene KCNJ11 encoding the Kir6.2 subunit of the ATP-sensitive K+ charmel have been described in patients with PND. We report a child with PND due to a lysine-to-arginine substitution at position 170(K170R) of gene encoding Kir6.2 Our patient was diagnosed at 7 weeks of age and had been treated with subcutaneous insulin for 6.5 years. Recently, our patient has been changed from subcutaneous insulin to oral glibenclamide therapy at a daily dose of 7.5 mg 3 times a day(0.9 mg/kg/day) at the age of 6.5 years. Before glibenclamide therapy, c-peptide level was 0.1 ng/ml(normal 1.0-3.5 ng/ml) and hemoglobin HbA1c level was 7.8%(normal <6%). After 6 days of treatment, her c-peptide and insulin levels were 2.3 ng/ml and $9.6{\mu}U/ml$(normal $5-25{\mu}U/ml$), respectively. After 1 month later, the insulin and c-peptide levels were in the nonnal range without any episodes of hyper- or hypoglycemia. This case demonstrated that oral sulfonylurea may be the treatment of choice in PND patients with KCNJ11 mutation even at a young age.

단순 베이즈 분류에서의 범주형 변수의 선택

김민선,최호식,박창이,Kim, Min-Sun,Choi, Hosik,Park, Changyi 한국통계학회 2015 응용통계연구 Vol.28 No.3

단순 베이즈 분류($Na{\ddot{i}}ve$ Bayes classification)는 출력변수가 주어졌을 때 입력변수들이 조건부 독립이라는 가정에 기반한다. 단순 베이즈 가정은 비현실적이지만 고차원의 확률 추정 문제를 일련의 일차원 확률 추정 문제로 단순화 시킨다는 장점이 있으며, 특히 스팸 메일 필터링, 추천 시스템(recommendation system) 등 방대한 데이터를 다루는 분야야에서 흔히 사용된다. 본 논문에서는 입력변수와 출력변수간의 카이제곱 통계량에 기반한 변수선택법을 제안한다. 이 방법은 단순 베이즈 분류의 장점인 데이터 처리 및 계산의 단순성을 유지하면서도 설명력이 있는 변수를 선택할 수 있으며 SNP(single nucleotide polymorphism)에 의한 질병의 분류 등의 초고차원 혹은 빅데이터에서 유용할 것으로 기대된다. $Na{\ddot{i}}ve$ Bayes Classification is based on input variables that are a conditionally independent given output variable. The $Na{\ddot{i}}ve$ Bayes assumption is unrealistic but simplifies the problem of high dimensional joint probability estimation into a series of univariate probability estimations. Thus $Na{\ddot{i}}ve$ Bayes classier is often adopted in the analysis of massive data sets such as in spam e-mail filtering and recommendation systems. In this paper, we propose a variable selection method based on ${\chi}^2$ statistic on input and output variables. The proposed method retains the simplicity of $Na{\ddot{i}}ve$ Bayes classier in terms of data processing and computation; however, it can select relevant variables. It is expected that our method can be useful in classification problems for ultra-high dimensional or big data such as the classification of diseases based on single nucleotide polymorphisms(SNPs).

김민선,백기주,김영석,나기열,Kim, Min-Sun,Baek, Ki-Ju,Kim, Yeong-Seuk,Na, Kee-Yeol 한국전기전자재료학회 2012 전기전자재료학회논문지 Vol.25 No.9

In this paper, TCAD assessment of 30-V class n-channel EDMOS (extended drain metal-oxide-semiconductor) transistors with DWFG (dual work function gate) structure are described. Gate of the DWFG EDMOS transistor is composed of both p- and n-type doped region on source and drain side. Additionally, lengths of p- and n-type doped gate region are varied while keeping physical channel length. Two-dimensional device structures are generated trough TSUPREM-4 and their electrical characteristics are investigated with MEDICI. The DWFG EDMOS transistor shows improved electrical characteristics than conventional device - i.e. higher transconductance ($g_m$), better drain output current ($I_{ON}$), reduced specific on-resistances ($R_{ON}$) and higher breakdown characteristics ($BV_{DSS}$).

GNPTAB 유전자에서 새로운 돌연변이가 확인된 뮤코지방증 III형 남매

김민선,박에스더,송아리,임민지,박형두,조성윤,진동규,Kim, Min-Sun,Park, Esther,Song, Ari,Im, Minji,Park, Hyung-Doo,Cho, Sung Yoon,Jin, Dong-Kyu 대한유전성대사질환학회 2018 대한유전성대사질환학회지 Vol.18 No.3

뮤코지방증 III alpha/beta는 GNPTAB 유전자의 돌연변이로 야기되는 점액(Mucolipids) 분해 능력 장애이며 상염색체 열성으로 유전된다. 이는 혈액에서 고농축의 점액을 검사하여 진단되며 유전자 검사를 통해 진단을 확인할 수 있다. 뮤코지방증 III형은 희귀하고 점진적으로 진행하는 대사장애로 증상은 3세 경에 나타나며 성장지연, 관절 경직, 관절통, 골격 이상, 심장 판막 이상, 반복되는 호흡기 감염, 평평한 얼굴과 낮은 콧대의 거친 얼굴, 지적장애 또는 학습 문제를 보인다. 본 증례는 성장 지연과 거친 얼굴을 보이는 4세, 2세 7개월 남매에서 targeted gene panel sequencing으로 [c.2715+1G>A (p.Glu906Leufs*4), c.2544del (p. Glu849Lysfs*22)] 두 개의 변이가 이형 접합체로 발견되어 뮤코지방증 III형을 진단하였으며 c.2544del 은 새로운 돌연변이로 대조군에서 발견되지 않았고 표현형과 연관성 고려 시 pathogenic variant로 해석된다. 이와 같이 GNPTAB 유전자에서 새로운 돌연변이가 확인되어 뮤코지방증 III형 남매 증례를 보고하는 바이다. 본 증례처럼 최근 분자유전학적 기술이 발달함에 따라 조기 진단이 가능해지고 진단 후 Case 1 환자에서와 같이 치료를 위하여 pamidronate 투약 가능하나, 이와 같은 보조적 치료 외에도 조기 진단을 받은 뮤코지방증 환자들을 위한 근본적인 치료법 개발을 위한 노력이 필요하다. Mucolipidosis type III (pseudo-Hurler polydystrophy) is a mucolipids degrading disorder caused by a mutation in the GNPTAB gene and is inherited by autosomal recessive. It is diagnosed by examining highly concentrated mucolipids in blood and the diagnosis can be confirmed by genetic testing. Mucolipidosis type III is a rare and progressive metabolic disorder. Its initial signs and symptoms usually occur around 3 years of age. Clinical manifestations of the disease include slow growth, joint stiffness, arthralgia, skeletal abnormalities, heart valve abnormalities, recurrent respiratory infection, distinctive facial features, and mild intellectual disability. Here, we are presenting two siblings of mucolipidosis type III, a 4-year-old female and a 2 years and 7 months old male with features of delayed growth and coarse face. The diagnosis was confirmed by [c.2715+1G>A(p.Glu906Leufs*4), c.2544del(p.Glu849Lysfs*22)] mutation in targeted gene panel sequencing. In this case, c.2544del is a heterozygote newly identified mutation in mucolipidosis type III and was not found in the control group including the genome aggregation database. And it is interpreted as a pathogenic variant considering the association with phenotype. Here, we report a Korean mucolipidosis type III patients with novel mutations in GNPTAB gene who have been treated since early childhood. Owing to recent development of molecular genetic techniques, it was possible to make early diagnosis and treatment with pamidronate was initiated appropriately in case 1. In addition to these supportive therapies, efforts must be made to develop fundamental treatment for patients with early diagnosis of mucolipidosis.

2011-2012절기 B형 인플루엔자 감염의 임상 양상

김민선,성현우,배이영,한승범,정대철,강진한,Kim, Min Sun,Sung, Hyun Woo,Bae, E Young,Han, Seung Beom,Jeong, Dae Chul,Kang, Jin Han 대한소아감염학회 2013 Pediatric Infection and Vaccine Vol.20 No.2

목 적 : 국내 B형 인플루엔자의 임상 양상 및 A형 인플루엔자와 비교를 위해 후향적 연구를 시행하였다. 방 법 : 2011-2012 인플루엔자절기에 multiplex PCR로 인플루엔자가 진단된 소아청소년 입원 환자들의 의무 기록 분석으로 B형 인플루엔자의 임상 양상과 함께 같은 기간 A형 인플루엔자와의 차이점을 조사하였다. 결 과 : 연구 기간 동안 진단 된 145명 인플루엔자 환자 중, A형 인플루엔자 66명, B형 인플루엔자 78명이 있었고, 1명은 A, B형 인플루엔자가 동시에 진단되었다. 이들은 기침(88.2%), 콧물(77.1%), 가래(60.4%) 등 호흡기 증상을 호소하며, 하기도 감염(49.3%) 및 상기도 감염(31.9%)으로 진단된 경우가 많았다. B형과 A형 인플루엔자 환자의 주요 증상 및 검사실 소견은 차이가 없었고, A형에 비해 B형 인플루엔자 환자의 입원 전 발열기간이 길었다(3.0일 vs. 2.5일, P=0.043). 결 론 : 임상 양상만으로 B형과 A형 인플루엔자 감별은 제한성이 있고, B형 인플루엔자 환자의 입원 전 발열 기간 3일을 고려한다면 진단 후 치료보다 감염 전 예방이 중요하다. Purpose: This retrospective study was performed to identify the clinical characteristics of influenza B infection and compare to influenza A infection. Methods: Medical records of patients diagnosed with influenza using a multiplex PCR test, admitted to Seoul St. Mary's Hospital, during the 2011-2012 influenza season were analyzed. Clinical and laboratory characteristics of influenza B patients were investigated and compared with those of influenza A patients. Results: A total of 145 influenza patients were enrolled during this study period. Among these, 66 and 78 patients were diagnosed with influenza A and B, respectively, and 1 patient was diagnosed with co-existing influenza A and B. Cough (88.2%), rhinorrhea (77.1%) and sputum (60.4%) were the most common symptoms among these influenza patients, and most were diagnosed with upper respiratory infection (31.9%) or lower respiratory infection (49.3%). In comparison to influenza A patients, influenza B patients were older ($4.7{\pm}4.1$ years vs. $3.3{\pm}2.5$ years, P=0.016), and the number of fever days before hospitalization were longer (3.0 days vs. 2.5 days, P=0.043). While sore throat (10.3% vs. 1.5%, P=0.039) and vomiting (20.5% vs. 6.1%, P=0.012) were more common in influenza B patients than in influenza A patients, other clinical and laboratory characteristics were not significantly different between the two groups. Conclusions: No significant differences in clinical and laboratory perspectives were manifested in influenza A and B infections. Preventive measures should be emphasized over treatment in influenza B due to prolonged fever duration before admission.

김규동 시론에 나타난 현실 인식과 동시성의 욕망

김민선(Kim Min-sun) 한국비평문학회 2010 批評文學 Vol.- No.38

This study is to examine 'Modernity' shown in Kim Gyu-dong's poetics in the 1950s and to clarify its direction. Especially, starting from similarities between Kim Gyu-dong's poetics and Kim Gi-rim's early poetics, this paper considers how his desire worked for the world literature in his poetics. Kim Gyu-dong's poetics is very similar to Kim Gi-rim's early poetics composed in the middle and late 1930s, in that his poetics established directivity in terms of the Western modern literature, but there are some differences found between them. Thus, this paper attempted to consider how the differences composed his poetics, while ultimately investigating the planning of literary coteries of 'Hubangi (the second half of the year)' in the 1950s, who agonized over the Korean literature in the magnetic field of the world literature. In Kim Gyu-dong's poetics in the 1950s, the literature of 'Modern Times' and 'Modern Times' introduced the Western modern styles and modes, while the premodern literature became prominent with the poetic styles and modes oriental, lyrical and melodious. His poetics was ver similar to Kim Gi-rim's early poetics in such an aspect, but there was a large difference left between them that his poetics didn't introduce the enjoyment of literature, which Kim Gi-rim recognized, and its possibility of literature as well. Moreover, since it didn't introduce the possibility of embracing literature, Kim Gyu-dong's poetics could advance into the world literature as literature for a few intellectuals, rather than as the Korean literature in a specific historical context called the South Korean society right after the Korean War. Nevertheless, as the contemporary Korean literature he introduced within the world literature could not reject the specific historical context as well, it came to be confronted with limitations. In other words, he desired the Korean literature to be within the world literature, but due to such a desire, the characteristics of the Korean literature ended up being ignored in a specific circumstance like Korea in the 1950s. That is, the reason why his 'Modernity' went blank can be explained with the results of his inferior complex for the world literature unlike Kim Gi-rim's 'Modern Times' and his overwhelming desire to situate the Korean literature within the world literature. Furthermore, such a case as Kim Gyu-dong's shows one of the aspects of imagination for the Korean literature within the world literature, which modernists might have had right after the Korean War.
