기존의 전통적인 보안모델 설계는 대표적 두 가지 문제점을 가지고 있다. 첫째, 인간에 대한 고려보다는 기술중심으로 설계·구현되었다. 이와 같은 구조는 조직 내 심리적 저항, 사용자 실수와 같은 인지적 취약성에 의해 무력화될 수 있다. 둘째, 네트워크 경계기반 보안모델로 설계되었다. 이와 같은 설계는 4차 산업혁명의 패러다임과 코로나19로 인해 빠르게 보편화되고 있는 비곙계 기반의 원격업무 환경에서는 적합하지 못하다. 본 논문에서는 이와 같은 전통적인 기술 중심 보안모델의 문제점을 개선할 수 있는 방안으로 비경계 기반 최신 보안모델인 제로 트러스트 보안모델 내 인간 특성 위협을 연계하여 보안정책을 수립·반영할 수 있는 방안을 제언하였다. 이를 통해 기술적으로 발생하는 각종 위협 외 인간 특성 위협으로부터도 강건한 보안모델 설계 방안을 제언한다. Traditional security model design presents two primary issues. First, these models have been developed and implemented with a technology-centered approach rather than considering human factors. Such structures can be undermined by cognitive vulnerabilities like psychological resistance within organizations and user errors. Second, these models are typically designed based on network perimeter security. This design is unsuitable for the boundary-less remote work environments rapidly becoming prevalent due to the Fourth Industrial Revolution and the COVID-19 pandemic. This paper proposes an approach to address these limitations by integrating human-centered threats within the Zero Trust security model, a state-of-the-art boundary-less security framework. By doing so, we suggest a robust security model design that can protect against both technical and human-centered threats.

이진용,김덕곤,한규철,Lee, Jin-Yong,Kim, Deog-Gon,Han, Kyu-Chul 대한한방소아과학회 2004 대한한방소아과학회지 Vol.18 No.2

Objective : Atopic dermatitis has a close relationship with degranulation of mast cell and separation of Histamine. As there's no experiment with herb, using Arctii Fructus, we investigated experimental influence of Arctii Fructus on degranulation of mast cell and separation of histamine in SD rat. Methods : The SD rats are classified into three groups. One group is normal one treated by normal saline before medical treatment. The other is control group prescribed to Compound 48/80 before normal saline treatment. And the third is experimental group prescribed to compound 48/80 after medical treatment of Arctii Fructus. Then, I investigated the experimental results by measuring the degree of degranulation and separation of histamine. The results of investigation on SD rat group showing the degree of inhibitory effect of degranulation of a mast cell are as follow, the normal group treated by normal saline reflecting the degree of degranulation is $6.10{\pm}0.20\;%$, the control group treated by only compound 48/80 is $87.56{\pm}11.00\;%$, the experimental group which treated by compound 48/80 and Arctii Fructus's medical treatment is $16.26{\pm}4.67\;%$. Results : The normal group treated by only normal saline reflecting the degree of degranulation is $6.10{\pm}0.20\;%$, the control group treated by only compound 48/80 is 87.56=11.00 %, the experimental group treated by compound 48/80 and Arctii Fructus's medical treatment is $16.26{\pm}4.67\;%$. This result indicates that the degree of degranulation of mast cell is obviously inhibited (p<0.0l) in the experimental group in comparison with control one. The analysis of data obtained from plasma, which collected from the experimented SDrats' hearts before their death, and the measurement of quantity of histamine secretion show the following results. The quantity of normal group and control one is $25.34{\pm}4.58$ nM, $348.59{\pm}30.77$ nM respectively, and experimental one prescribed to compound 48/80 after medical treatment of Arctii Fructus is $263.56{\pm}21.34$ nM. This result indicates that separation of histamine isobviously inhibited in the experimental group in comparison with control one (p<0.05). Conclusions : Arctii Fructus does obviously inhibit the degree of degranulation of mast cell (p<0.0l) and separation of histamine in the plasma (p<0.05).

단계양수시험 해석시 시간선택이 해석결과에 미치는 영향

이진용,송성호,이강근,Lee Jin-Yong,Song Sung-Ho,Lee Kang-Kun 한국지하수토양환경학회 2005 지하수토양환경 Vol.10 No.2

단공 수리시험으로서의 단계양수시험은 일반적으로 대수층 및 우물의 생산성 혹은 효율을 평가하기 위해 수행되어 왔다. 단계양수시험은 기본적으로 초기에 저양수량으로 양수를 하며 양수관정의 수위가 안정되면 다음 단계의 고양 수량으로 다시 수위가 안정될 때까지 양수를 지속한다. 이러한 과정은 최소 3단계 이상 반복되며 각 단계별 양수지속시간을 동일하여야 한다. 본 기술자료에서는 그 동안 국내에서 수행된 단계양수시험의 해석과 관련하여 몇 가지 문제점들을 살펴보았다. 그 결과 단계양수시험에 대한 부적절한 해석결과는 주로 잘못된 해석개념 및 불완전한 현장 양수자료와 관계가 큰 것으로 파악되었다. Step-drawdown test has been generally conducted to evaluate productivity or efficiency of both aquifer and well. In general step-drawdown test, pumping with a low constant discharge rate is conducted in the first stage until the drawdown within the well stabilizes. And then the groundwater is pumped with a higher rate in the next step until the drawdown stabilizes once more. This process is repeated at least three times (steps), with the equal duration. In this paper we tried to review some critical problems related to the step-drawdown test, which were revealed in the process of field practices and analyses. The problems, referred in this paper are mainly associated with the incorrect conceptual approach for analysis and incomplete data collection in the field test.

소양강 탁수 현황과 저감에 대한 수리학적 분석

이진용,Lee, Jin-Yong 한국지하수토양환경학회 2008 지하수토양환경 Vol.13 No.6

소양강물은 춘천과 서울지역 시민의 중요한 수원이다. 2006년 태풍 에위니아로 악화된 탁수현상은 예년과 달리 280일 이상 지속되었으며 이로 인하여 춘천 및 서울지역 물 공급에 차질을 빚었다. 한편 소양강 유역의 약 55%에 해당하는 고랭지밭의 토사유출이 탁수현상의 주요원인으로 꼽히며 이와 함께 무분별한 산지개간, 도로의 확포장, 임도개설 등도 탁수를 가중시키는 것으로 알려진다. 본 연구에서 2006년 6월${\sim}$2008년 8월간의 소양강 유역의 탁도, 강수량, 댐수위 등을 분석한 결과 탁도는 일 강우와 49일의 지연시간을 두고 최대의 상관성(r = 0.28)을 보였으며 특히 댐 수위와는 4일의 지연시간에 대해 탁월한 상관성(r = 0.60)을 나타냈다. 그리고 2006년과 2007년 두 차례 발생한 탁수의 지속기간과 거리별 탁도 자료를 이용하여 분석한 결과 취수원인 팔당댐에 탁수(10 NTU)가 도달하기 위한 소양강댐의 기준 탁도는 약 31 NTU로 추정되었다. 또 분석을 통해 향후 탁수발생 시 지속기간을 예측할 수 있는 지배감쇠곡선(master recession curve)을 제시하였다. Water in Soyang River is an essential source for citizens of Chuncheon and Seoul areas. In 2006, turbid water in Soyang River aggravated by the typhoon Ewiniar, sustained for over 280 days unlike conventional years, then which interrupted water supply of Chuncheon and Seoul areas. Soil erosion derived from high cool lands constituting about 55% of Soyang River area is considered one of main causes for the turbid water, including imprudent development of mountainous area, road expansion, and road construction for forestry. According to analysis of turbidity, precipitation and reservoir level in Soyang River region for June 2006${\sim}$August 2008, the turbidity showed a peak correlation (r = 0.28) at a lag time of 49 days and especially did an excellent correlation (r = 0.60) with the reservoir level at a lag of 4 days. In the meantime, a critical turbidity of 31 NTU at Soyanggang Dam was estimated, over which would cause turbid water at Paldang Dam. In addition, a master recession curve was suggested, from which sustaining time of turbid water can be predicted.

과배란 유도 월경주기중 난포액내 Androstendione 및 Testosterone 농도에 관한 연구

이진용,윤보현,김정구,문신용,장윤석,Lee, Jin-Yong,Yoon, Bo-Hyun,Kim, Jung-Goo,Moon, Shin-Yong,Chang, Yoon-Seok 대한생식의학회 1986 Clinical and Experimental Reproductive Medicine Vol.13 No.1

Follicular flxid (FF) and their matched oocytes were obtained from 58 follicles of 27 women who underwent an in vitro fertilization (IVF) procedure with ovarian hyperstimulation by clomiphene citrate(n=8), hMG(n=9),FSH/hMG(n=10). Follicular aspiration was performed 36 hours after human chorionic gonadotropin administration. The concentcation of androstendione (ADD), testosterone (T) was correlated with hyperstimulation regimens, the morphology of the oocyte-corona-cumulus complex (OCCC), oocyte fertilization, and the incidence of pregnancy after embryo transfer. The results were as follows. 1. According to hyperstimulation regimens, there was no significant differance in FF ADD and T concentrations of the similar morphology of OCCC. 2. In clomiphene-treated and FSH/hMG-treated cycles, FF ADD concentrations of preovulatory oocytes were 43.09${\pm}$9.53 ng/ml and 59.46${\pm}$9.09 ng/ml, those of immature occytes were 96.98${\pm}$16.55 ng/ml and 116.13${\pm}$36.81 ng/ml, those of atretic oocytes were 246.5 ${\pm}$9.25 ng/ml and 634.25${\pm}$9.25 ng/ml respectively, reflecting the significant relationship between FF ADD level and morphologic maturity of OCCC (p<0.05). But in hMG-treated cycles, such relationship was not found (p>0.1). In clomiphene-treated and FSH/hMG-treated cycles, FF T concentrations of preovulatory oocytes were 11.37${\pm}$2.38 ng/ml and 11.68${\pm}$1.73 ng/ml respectively which were significantly lower than those of atretic oocytes (25.1${\pm}$7.50 ng/ml and 23.25${\pm}$0.95 ng/ml respectively) (p<0.05). But in all cycles, FF T concentrations of immature oocytes were not significantly different from those of preovulatory oocytes, artetic oocytes (p>0.1). 3. In hMG-treated and FSH/hMG-treated cycles, FF ADD concentrations of fertilized oocytes were 32.43${\pm}$4.09 ng/ml and 42.61${\pm}$4.82 ng/ml respectively which were significantly lower than those of non-fertilized oocytes (72.18${\pm}$17.31 ng/ml and 108.09${\pm}$17.32 ng/ml respectively) (p<0.05), but in clomiphene-treated cycles there was no significant difference (p>0.1). In FSH/hMG-treated cycles, FF T concentration of fertilized oocytes was 7.33${\pm}$1.06 ng/ml which was significantly lower than that of non-fertilized oocytes (20.3${\pm}$6.21 ng/ml) (p>0.02), but in clomiphne-treated and hMG-treated cycles there was no significant difference (p>0.1). 4. In all cycles FF ADD and T concentrations did not correlated with the success of pregnancy after embryo transfer. Above results suggested that FF ADD and T may play an important role in oocyte maturation and fertilization, but their relationship with the success of psegnancy was not found.

지하 유체주입 지하수 관정의 설치 및 허가에 관한 규정: 미국 미주리주

이진용,Lee Jin-Yong 한국지하수토양환경학회 2005 지하수토양환경 Vol.10 No.5

오염지하수에 대한 복원시 필요한 주입관정, 지하수 인공함양을 위한 주입정 및 지열펌프에 사용되는 지하수 관정 등 지하수 관정을 이용하는 다양한 활동이 향후 국내에서 활발해질 것으로 사료된다. 그러나 이에 관한 법적 규정이 충분치 않아 일반 국민이나 담당 공무원에게 실무적으로 혼란이 있을 수 있다. 이에 미국 미주리주의 관련 규정 몇 가지를 간단히 소개함으로써 이에 관한 규정이 전문가들의 논의를 거쳐 국내에서도 속히 마련되기를 바란다. It is expected that use of groundwater wells for contaminated groundwater remediation, artificial groundwater recharge and geothermal heat pump systems is increasing in the future in Korea. Some practical confusions may be produced due to lack of regulations related to permits and registrations of these types of wells. This short note is intended to draw attention of relevant professionals by shortly introducing some relevant code of state regulations in Missouri, USA.

이진용,윤병구,최영민,신창재,장윤석,Lee, Jin-Yong,Yoon, Byung-Koo,Choi, Young-Min,Sin, Chang-Jae,Chang, Yoon-Seck 대한생식의학회 1990 Clinical and Experimental Reproductive Medicine Vol.17 No.2

Serum CA 125 was measured with immunoradiometric assay in fourty-one patients of endometriosis Serum CA 125 levels (Mean ${\pm}$ SEM, U/ml)in patients with endometriosis were 13.8${\pm}$3.3 in stage I , 17.3${\pm}$3.0 in stage II, 23.4${\pm}$4.9 in stage III, and 64.5${\pm}$13.2 in stage IV, which showed increment according to the stage of endometriosis. Serum levels in stage IV only were significantly elvated than those in control (15.3${\pm}$2.2), and those in advanced stage(III and IV ; 47.1${\pm}$9.5)were significantly higher than those in earlier stages (15.9${\pm}$2.2)and control. The assay revealed a sensitivity of 31.7% and the frequency of elevated levels (> 30.3 U/ml)in stage I, II, III and IV was 9. 1%, 18.8%,33.3%, and 87.5% respectively. Sensitivity in advanced stage was higher than that in earlier stage (64.3% vs. 14.8%). There data suggest that serum CA 125 assay might be a useful diagnostic tool in the advanced stage of endometriosis.
