Since the mid-1930s, intellectuals of colonial Korea had become professionals of social science academics. In this paper, I tracked the whereabouts of this professional knowledge in total war period. After political conversion(1938), In Jeongsik(印貞植) obtained and produced by himself the data which were more detailed and accurate than before for the society of colonial Korea. Using these indexes, In defined the historical status of it. At the same time, he compared colonial Korea with Southeast Asia, China, and Manchuria. Firstly, In argued that capitalistic industrialization was advanced in colonial Korea under Japanese imperialism, on the contrary, feudalism had been exacerbated in Southeast Asia since colonization by Western imperialism. Secondly, he represented China as a stagnant society based on the theory of "Asiatic mode of production"(K. Wittfogel), excepting colonial Korea from the range of that theory. Finally, In argued that Korean society was modernized based on the fact that the system of nuclear family was overwhelming, in contrast to Manchuria which had been evaluated as a large family system society. However, In"s claims were the answers to the questions suggested from Japanese resident intellectuals in Korea. These questions, produced in the asymmetry of power between empire and colony, were to serve the purpose of Japanese imperialism to mobilize colonial Korean society. In, without denying these questions, only looked to the others, neighboring Asian states, which were evaluated inferior than Korea by himself. After all, In neither could recognize accurately the "colonial Korea", nor fairly neighboring others. Disregarding the violence of questions he tried to answer, In distorted the history and reality of others. The way that In Jeongsik walked on as a social scientist of colonial Korea, needs to be remembered as the typical case that clearly says why colonial intellectuals fail to know their society and others accurately.

The Cretaceous Kyongsang Basin is known to be composed of several tectonic blocks (or subbasins) with each distinct stratigraphic succession. The study area represents a major part of one of these blocks, i. e. the $\check{U}is\check{o}ng$ block. The area is charaterized by a suite of WNW-trending sinistral strike-slip faults as well as a number of ring faults. A total of 292 independently oriented core samples were drilled from 23 sites, covering virtually all the formations of the Cretaceous $Ky\check{o}ngsang$ Supergroup. Alternating field and thermal demagnetization experiments were conducted to reveal the primary magnetization. Due to the homoclinal nature of the strata in the area, it was not possible to make use of the conventional fold test It is, however, believed that the primary remanent components have been obtained from the majority of the formations, considering the similarity of the palaeomagnetic pole positions with those of contemporary strata of other blocks and the existence of antiparallel reversed remanence. It was found neither any significant difference in magnetic declination on each side of the strike-slip faults nor systematic change of magnetic declination with distance from the fault-line. This does not support such a block rotation hypothesis associated with the strike-slip faulting in the area as alleged by some authors. The samples from the outcrops on or near the fault-lines were severely overprinted by the recent magnetic fields regardless of age and lithology. Epithermal Au-Ag-Cu-Pb-Zn mineralizations are known along some fault lines in the area. It is interpreted that these two facts are closely related with fluid circulations along the fracture zones caused by fault activities. In regard to the age of the strata as deduced from the magnetostratigraphic consideration, the $Ch\check{o}mgok$ formation and the lower strata should be older than Barremian or 124 Ma. The age of volcanics of the $Yuch^{\prime}\check{o}n$ Group sampled in this study should be younger than Campanian or 83 Ma.

김인수(In Soo Kim),한재복(Jae Bok Han),장성주(Seong Joo Jang) 대한방사선과학회(구 대한방사선기술학회) 2014 방사선기술과학 Vol.37 No.2

본 연구에서는 관상동맥 중재술로 관상동맥 약물방출 스텐트(drug-eluting stent, DES) 삽입 후 스텐트 골절에 대한 임상적 특성, 결과 및 예후에 대하여 연구하였다. 약물방출 스텐트 시술을 받고 추적 관상동맥조영술을 실시한 4,701명 환자에서 스텐트 골절이 발생한 환자는 32명(남:여=19:13, 평균연령 62.44±9.8세, 0.68%)이었다. DES의 종류별 스텐트 골절의 빈도는 SES(sirolimus- eluting stents) 19(59.4%), PES(paclitaxel-eluting stents) 9명(28.1%), BES(biolimus A9-eluting stents) 2명(6.3%), EES(everolimus-eluting stents) 1명(3.1%), EPC(endothelial progenitor cell capture stent) 1명(3.1%), ZES(zotarolimus-eluting stents) 0명(0%) 이었다. 표적 병변은 우관상동맥 13명(40.6%) 좌전하행지 16명(50.0%), 좌회선지 3명(9.4%)이었다. 각 혈관의 병변 형태는 복잡병변인 B2, C형이 25명(69.4%)이었다. 스텐트 골절 환자 중 스텐트 내 협착은 17명(53.1%)이었으며, 스텐트 골절 병변에 대한 치료는 내과적 관찰 16명(50.0%), 동종의 관상동맥 DES 시술 3명(9.4%), 이종의 관상동맥 DES 시술 10명(31.3%), 관상동맥 풍선 확장술 3명(9.4%)이었다. 추적검사에서는 32.9±12.4개월 동안 스텐트 골절로 인한 사망을 포함한 심장사는 발생하지 않았다. 결론적으로 관상동맥 중재술로 관상동맥 DES를 시술받은 추적관찰 대상 환자에서 3.7년 추적관찰 기간동안 스텐트 골절 발생률은 0.68%로 나타났으며, PES보다 SES에서 많은 발생 빈도를 보였다. 좌전하행지와 복잡병변에 대한 시술 후 스텐트 골절이 많이 발생하였다. 또한 스텐트 골절 정도와 협착 병변이 중대한 경우에만 관상동맥 중재술을 실시하였으며, 추적관찰 기간 중 스텐트 골절이 있는 환자는 병용 항혈소판 요법을 지속적으로 투여하였다. 특히 사망을 포함한 주요 심장사건에 관련하여 스텐트 골절과 연관된 심장사의 발생률은 매우 낮은 것으로 나타났다. 본 연구를 통해서 스텐트가 가지고 있는 특성 스텐트 디자인이 폐쇄형(closed cell) 디자인 SES에서 발생 빈도가 높음을 제시함으로써 스텐트 개발에 도움이 될 거라 판단된다. Many studies have suggested that in the era of Drug-Eluting Stents(DES) are one of the causes of In-Stent Restenosis(ISR) of Stent Fracture(SF). The present study sought to evaluate clinical characteristics of patients with stent fracture after successful DES implantation. The 4,701 patients were selected for analysis who underwent a follow-up coronary angiography irre-spective of ischemic symptoms. The overall incidence of SF was 32 patients(male:female=19:13, Av. age 62.44±9.8year, 0.68%). Fractures of Sirolimus-Eluting Stents(SES), Paclitaxel-Eluting Stents(PES), Biolimus A9-Eluting Stents(BES), Everolimus-Eluting Etents(EES), Endothelial Progenitor Cell Capture Stent(EPC) and Zotarolimus-Eluting Stents(ZES) are accounted for 19(59.4%), 9(28.1%),2(6.3%),1(3.1%),1(3.1%)and 0(0%) respectively. SF developed in the left Anterior Dscending(LAD) artery in 16 patients(50%) and in complex(type B2, C) lesions in 25 patients(69.4%). Ten patients were treated with heterogenous DES, the rest being treated with either homogenous DES(3 patients), plain old balloon angioplasty(3 patients), or conservative medical treatment(17 patients). None of the patients with SF suffered from cardiac death dur-ing a follow-up period of 32.9±12.4 months. The overall rate of DES fracture over up to 3.7 years of follow-up was 0.68% with higher incidence in SES than in PES. SF frequently occurred in the LAD artery and in complex lesions. Of the patients with SF, coronary intervention was performed only when the binary restenosis lesion was significant. During the follow-up, patients with SF have continued on combination antiplatelet therapy. There is a very low rate of major adverse cardiac events(post-detection of SF), especially cardiac death associated with SF.

In_0.49Ga_0.51P/GaAs 이종접합 구조의 표면 광전압 특성

김정화,김인수,배인호,Kim, Jeong-Hwa,Kim, In-Soo,Bae, In-Ho 한국진공학회 2010 Applied Science and Convergence Technology Vol.19 No.5

Metal-organic chemical vapour deposition (MOCVD) 법으로 성장된 $In_{0.49}Ga_{0.51}P$/GaAs 이종접합 구조의 특성을 표면 광전압(surface photovoltage; SPV) 분광법으로 조사하였다. SPV 측정은 입사광의 세기, 변조 주파수, 온도의 함수로 수행하였다. 상온에서 시료의 띠간격 에너지(band gap energy)는 GaAs와 $In_{0.49}Ga_{0.51}P$는 각각 1.400 및 1.893 eV이었다. 광세기를 증가시킴에 따라 SPV 크기는 증가하는 반면에, 변조 주파수를 증가시킴에 따라 SPV 크기는 감소하였다. 그리고 SPV 스펙트럼의 온도 의존성으로부터 GaAs와 $In_{0.49}Ga_{0.51}P$의 띠간격 에너지의 변화를 Varshni 및 Bose-Einstein 표현에 의해 분석하였다. We report the surface photovoltage (SPV) properties of $In_{0.49}Ga_{0.51}P$/GaAs heterostructure grown by metal-organic chemical vapour deposition (MOCVD). The SPV measurements were studied as a function of modulation beam intensity, modulation frequency and temperature. From a line shape analysis of room temperature derivative surface photovoltage (DSPV) spectrum, the band gap energies for GaAs and $In_{0.49}Ga_{0.51}P$ transitions were 1.400 and 1.893 eV respectively. The surface photovoltage (SPV) increases with increasing the light intensity and temperature, whereas the SPV decreases with increasing the modulation frequency. From the temperature variation of the energy gaps, we have analysis by both Varshni and Bose-Einstein type expressions.

경상분지 남서부 진교-사천 지역 전기백악기 퇴적암에 대한 고자기 연구

김인수,강희철,이현구,Kim, In-Soo,Kang, Hee-Cheol,Lee, Hyun Koo 대한자원환경지질학회 1993 자원환경지질 Vol.26 No.4

A total of 264 independently oriented core samples were collected from 26 sites in the southwestern part (the Naktong Trough) of the Cretaceous $Ky{\check{o}}ngsang$ Basin in south Korea. The sampled formations comprise the sedimentary Shindong and the Hayang Groups of the Lower Cretaceous age. Alternating field and thermal demagnetizations were conducted. Characteristic remanent magnetization (ChRM) was relatively easily isolated in each formation except in the Chinju formation, from which only remagnetization circles were observed. Even though an extensive use of the fold test was not possible due to the nearly homoclinal nature of the strata in the area, we believe that the ChRM of each formation is of primary origin based on the following grounds: The in-situ ChRM direction of each formation is different from the present geomagnetic field direction. Fisherian precision parameter becomes enhanced through the tilt correction in all formations, closely to the values required for a positive fold test. Three out of the five studied formations pass the reversal test. The mean palaeomagnetic pole position from the studied area is found to be statistically different from the contemporary pole from the Chinese block exclusive of the Shandong area. The difference in magnetic declination suggests a $14.5^{\circ}$ (${\pm}10.5^{\circ}$) clockwise rotation of the studied area relative to the Chinese block comprising the west of the Tan-Lu fault. On the other hand, any significant difference in magnetic inclination and concurrent palaeolatitude is not observed between the studied area and China as well as the other area (Taegu-Andong area) in the $Ky{\check{o}}ngsang$ Basin. The dual nature of the magnetic polarity confirmed in all formations suggests an older than 124 Ma (Neocomian or older) age of the studied sedimentary strata.

생물증강법을 이용한 오염해양준설토의 환경친화적 정화 및 재활용

김인수,하신영,고성철,Kim, In-Soo,Ha, Shin-Young,Koh, Sung-Cheol 한국미생물학회 2015 미생물학회지 Vol.51 No.4

국내의 경우 항만과 연안해역 준설로 인하여 연간 수 천만톤 이상 준설토사가 발생하며 매년 증가하고 있으나, 대부분 투기장에 장기간 방치되며, 더구나 2012년부터 런던협약에 의해 해양투기가 금지되고 있어 환경친화적인 준설토처리 및 재활용기술개발이 시급하다. 준설토 재활용기술에서는 중간처리과정후 발생하는 현탁수(유기물과 중금속 함유 $10{\mu}m$ 미만 미세오염퇴적물 포함)의 처리가 필요한데 현재 이 기술은 연구되어 있지 않다. 본 연구에서는 복합유용미생물제제(BM-S-1)을 이용하여 미세해양오염퇴적물($10{\mu}m$ 이하 입자)내 오염되어 있는 유기물질, 영양염류 및 중금속을 정화하여 배출함으로써 오염퇴적물 정화처리수 방류수질 기준을 충족하고자 하였다. BM-S-1 복합미생물제제를 이용한 해양준설토의 친환경정화시스템으로서 일일 50 L 처리용량의 Lab scale 실험장치를 HRT 6.5일, BOD 용적부하 $0.2-0.6kg/m^3{\cdot}day$의 조건으로 생물반응기를 100일 이상 운전하였다. SCOD, T-N 및 T-P의 제거효과는 각각 96.1%, 92.0% 및 79.0%로 나타나 오염미세퇴적토 내의 유기물의 처리효과가 매우 양호하였다. 또한 몇 가지의 중금속(Zn, Ni 및 Cr) 처리에도 효과적이었다. 아울러 물리적으로 분리하기 어려운 $10{\mu}m$ 이하의 미세토양의 고액분리가 가능함을 확인하였다. 미생물군집구조를 분석한 결과 Flavobacteria 및 Gammaproteobacteria 강이 매우 우점하였으며, 이들에 속한 미생물종들은 해양 내의 각종유기물(다당류, 단백질 및 기타 생물중합체)을 처리하는 것으로 알려졌다. 따라서 본 실험에서 사용된 BM-S-1 미생물제제와 처리시스템은 고농도의 염분이 함유되어있는 유기물 및 중금속 오염 해양퇴적물 정화에 효율적으로 적용가능한 것으로 판단되며, 정화, 분리된 미세해양퇴적물은 목적에 맞게 재사용 가능할 것으로 사료된다. Occurrences of coastal dredged materials are ever increasing due to port construction, navigational course maintenance and dredging of polluted coastal sediments. Ocean dumping of the coastal dredged materials has become virtually prohibited as London Treaty will be enacted as of the year 2012. It will be necessary to treat and recycle the dredged materials that may carry organic pollutants and heavy metals in a reasonable and effective process: collection of the dredged materials, liquid and solid separation, and treatment of organic compounds and heavy metals. In this study we have developed a continuous bioreactor system that can treat a mixture of silt and particulate organic matter using a microbial consortium (BM-S-1). The steady-state operation conditions were: pH (7.4-7.5), temperature ($16^{\circ}C$), DO (7.5-7.9), and salt concentration (3.4-3.7%). The treatment efficiencies of SCOD, T-N and T-P of the mixture were 95-96%, 92-99%, and 79-97%. The system was also effective in removal of heavy metals such as Zn, Ni, and Cr. Levels of MLSS during three months operation period were 11,000-19,000 mg/L. Interestingly, there was little sludge generated during this period of operation. The augmented microbial consortium seemed to be quite active in the removal of the organic component (30%) present in the dredged material in association with indigenous bacteria. The dominant phyla in the treatment processes were Proteobacteria and Bacteroidetes while dominant genii were Marinobacterium, Flaviramulus, Formosa, Alteromonadaceae_uc, Flavobacteriaceae_uc. These results will contribute to a development of a successful bioremediation technology for various coastal and river sediments with a high content of organic matter, inorganic nutrients and heavy metals, leading to a successful reuse of the polluted dredged sediments.

김포(金浦))지역 대동누층군(大同累層群)에 대한 고자적(古磁的) 연구

김인수,민경덕,이미영,강희철,전희영,Kim, In-Soo,Min, Kyung Duck,Lee, Mi Yeong,Kang, Hee-Cheol,Chun, Hee Young 대한자원환경지질학회 1993 자원환경지질 Vol.26 No.2

A total of 111 independently oriented core samples were drilled at 12 sites in fue Kimpo area ($37.70^{\circ}N$, $126.55^{\circ}E$) of the Taedong Supergroup. The Taedong strata are composed of sandstone, conglomeratic sandstone, shale and thin coal seams. The age of the strata is known to be Late Triassic-Early Jurassic according to freshwater Esfuerites and plant fossil (Dictyophyllum-Clathropteris flora) contents. Through AF and thermal demagnetization, an area-mean ChRM direction of $D=48.3^{\circ}\;I=40.3^{\circ}\;{\alpha}_{95}=7.9^{\circ}\;k=59.5$, n=7 was obtained. It passed fold and reversal test in the formation-mean level. Fold test was not significant in the area-mean level. The palaeomagnetic north pole calculated from the area-mean lies at $46.3^{\circ}N$, $222.0^{\circ}E$ with dp=5.7, $dm=9.5^{\circ}$. This pole position is very similar to those of the South China Block (SCB) in Triassic times. Palaeolatitude of the Kimpo area in the Taedong times was $23.0^{\circ}N$, again very similar to the palaeolatitude of the South China Block in the Late Triassic. This low latitude of the study area at the time of deposition explains the tropical-subtropical nature of fossil contents of the Taedong Supergroup.

Photoreflectance 측정에 의한 InxGa₁-xAs(0.03≤X≤0.11) 에피층의 특성 연구

김인수(In-Soo Kim),손정식(Jeoog-Sik Son),이철욱(Cheul-Wook Lee),배인호(In-Ho Bae),임재영(Jae-Youog Leem),한병국(Byung-Kuk Han),신영남(Young-Nam Shin) 한국진공학회(ASCT) 1998 Applied Science and Convergence Technology Vol.7 No.4

Molecular Beam Epitaxy(MBE)법으로 성장된 In_xGa_(1-x)As/GaAs 에피층에 대해 photoreflectance (PR)실험을 통해 특성을 조사하였다. PR 측정결과 성장된 In_xGa_(1-x)As 에피층의 띠간격 에너지(E。) 신호가 시료의 변형(strain)에 의해 heavy-hole(E。(HH))과 light-hole(E。(LH))로 분리되어 관측되었다. 에피층의 조성과 변형은 각각 시료에서의 E。(HH) 및 Eo(HH)와 Eo(LH)신호의 에너지 차이를 이용하여 구하였다. 또 160 K이하의 온도에서는 Eo(LH)의 신호가 사라짐을 볼 수 있었다. Franz-Keldysh oscillation(FKO) 피크로부터 계산되어진 InGaAs/GaAs 계면전장 (E)은 In 조성의 증가에 따라 0.75×10^5 V/㎝에서 2.66×10^5 V/㎝로 증가하였다. In 조성이 x=0.09인 시료에 대한 PR신호의 온도의존성 실험에서 Varshni 계수와 Bose-Einstein 계수들을 각각 구하였다. Photoreflectance (PR) measurents have been performed on In_xGa_(1-x)As/GaAs grown by molecular beam epitaxy (MBE). Bandgap (E。) of In_xGa_(1-x)As epilayer measured from PR was separated as heavy-hole (E。(HH)) and light-hole (E。(LH)) by strain effect. The compositions and the strains of epilayer were obtained from the energy value of E。(HH) and from enegy difference of E。(HH) and E。(LH), respectively. In addition, the PR signal of E。(LH) was diminished below 160 K. The interface electric field (E) of InGaAs/GaAs was increased from 0.75×10^5 V/㎝ to 2.66×10^5 V/㎝ as In composition increased, which was calculated from Franz-Keldysh oscillation (FKO) peaks. As the temperature dependence of the PR signal at x=0.09 sample, we obtained Varshni and Bose-Einstein coefficients.

경주-울산일원에 대한 지역지질 특성연구 : 울산단층주변 화강암류의 잔류자기와 대자율

김인수,손문,정현정,이준동,김정진,백인성,Kim, In-Soo,Son, Moon,Jung, Hyun-Jung,Lee, Joon-Dong,Kim, Jeong-Jin,Paik, In Sung 대한자원환경지질학회 1998 자원환경지질 Vol.31 No.1

A total of 469 granitic samples were collected from 44 sites in the Ulsan fault area, southeast Korea. According to the previous petrographic studies, the granitic rocks have been divided into four groups (Hornblende biotite granodiorite, Hornblende granite, Biotite granite and Alkali-feldspar granite). NRM intensities, values of low field magnetic susceptibility, and magnetic behaviors during stepwise demagnetization experiments suggest rather a three-fold classification: In this scheme, Hornblende granite and Biotite granite are grouped together, as they did not show any significant differences in magnetic characteristics. Based on the Ishihara (1979)'s criterion, Alkali-feldspar granite is classified as ilmenite-series granite, whereas others are classified as magnetite-series granite. In the eastern part of the study area including the Tertiary basin area, declinations of site-mean characteristic remanent magnetizations (ChRMs) show clockwise deflection of more than 30 from the reference direction of east Asia. Both along and in the adjacent region of the Ulsan fault-line, however, no deflection of remanent direction was observed. A boundary line between the deflected and undeflected site-mean ChRMs is defined in this study, which runs roughly parallel to the Ulsan fault-line at the distance of about 6km eastward from the fault-line. We suggest that this newly found boundary line, which we call Yonil tectonic line, released dextral simple shear stress acted in the southeastern part of the Korean peninsula during the opening stage of the East Sea in the Early Cenozoic.

THE EFFECT OF DIFFERENTIAL MODULATION OF N-METHYL-D-ASPART ATE RECEPTOR ON THE VIABILITY OF PRIMARY CULTURED NORMAL HUMAN ORAL KERATINOCYTES

김인수,이원,김성훈,최봄,Kim, In-Soo,Lee, Won,Kim, Seong-Hun,Choi, Bohm Korean Association of Maxillofacial Plastic and Re 2006 Maxillofacial Plastic Reconstructive Surgery Vol.28 No.4

In the present study, I investigated the effects of N-methyl-D-aspartate (NMDA), arachidonic acid (AA), and Nitric Oxide Synthase Inhibitor (NOS-I), alone or in combination, on the viability of cultured primary normal human oral keratinocytes (NHOK). Specifically, we examined whether AA and NOS-I could protect primary NHOK from glutamate cytotoxicity. The purpose of this study was therefore the preliminary study for the examination of the interaction between these agents and NHOK in order to elucidate the mechanisms by which epithelial growth and regeneration are regulated. NHOK were obtained from gingival tissue of 20 individuals aged 20 to 29, and third passage (P3) cells were used for this study. Cell viability was measured by the MTT assay. NMDA and NNA, a calcium dependent NOS inhibitor, induced an initial increase in cell number, which subsequently decreased by the $7^{th}$ day. Low concentration of AA ($0.5\;{\mu}M$ & $1\;{\mu}M$) induced an increase in cell number while high concentrations of AA ($5\;{\mu}M$ & $10\;{\mu}M$) induced a decrease in cell number. The decrease in cell number induced by NMDA at the $7^{th}$ day was abolished by the addition of low concentrations of AA ($0.5\;{\mu}M$ & $1\;{\mu}M$) or NOS inhibitors. Low concentrations of AA ($0.5\;{\mu}M$ & $1\;{\mu}M$) or NOS inhibitors may protect the NHOK from NMDA induced cytotoxicity. These reactions might be related to the NMDA receptor in the cell and the change of the intracellular calcium ion concentration.
