읍지(邑誌)와 방목(榜目), 호적(戶籍)을 통해 본 대구 출신 급제자들

한상우 ( Han¸ Sangwoo ) 대구사학회 2021 대구사학 Vol.144 No.-

조선시대 대구에서는 몇 명의 문과급제자들이 배출되었을까. 이 물음에 답하기 위해 본 연구는 조선시대 이후 편찬된 대구의 邑誌, 市史, 榜目과 대구부호적대장 등을 활용하여 대구 출신 급제자들을 확인하였다. 읍지와 시사, 방목을 비교하여 확인할 수 있었던 대구 출신 급제자들은 총 79명이다. 그러나 이 과정에서 자료들마다 급제자들의 명단과 정보가 상이하다는 점을 확인할 수 있었다. 그 가운데 실제로 대구에 거주한 자들을 확인하기 위해 1681년부터 1876년까지에 걸쳐 남아 있는 대구의 호적에서 17세기 후반 이후의 급제자들과 그 가족들을 추적하였다. 그 결과, 읍지와 방목 속 대구 급제자들이 모두 대구에 거주했던 것은 아니며, 반대로 실제로 대구에 거주했더라도 읍지에서 누락된 경우가 있었다. 즉, 대구 출신 급제자에 대한 기억은 그들의 실제 대구 거주 여부뿐 아니라 다면적으로 평가되었던 것이다. 그리고 대구 출신 급제자 확정을 어렵게 하는 요인 중 하나는 그들이 잦은 이주였다. This study finds the successful candidates of the civil exam who resided in Taegu during the Chosŏn Dynasty. The information of the successful candidates of Taegu was collected from gazetteers published in 1768, 1832, 1924, 1995 Taegu and the rosters of the successful candidates. As a result, this study makes the list of 79 successful candidates of Taegu. However, it is interesting that records and lists of the successful candidates in each source are different. This study traces the successful candidates in the Taegu household registers published from 1681 to 1876 to check their residence in Taegu and finds that gazetteers recorded the successful candidates selectively. One reason for the selective record is the frequent migration of successful candidates. The migration cases of the Sunch'ŏn Pak family, the most successful family in the civil exam in Taegu, show us that even successful candidates were apt to leave their hometown due to their political attitude and reputation in local society. This is why difficult to ascertain how many successful candidates of the civil exam Taegu produced for 500 years. (Dept. of History, Ajou University, hansw@ajou.ac.kr)

Self-assembly of tumor-targeting RNA nanoball for carrier-free delivery of therapeutic RNA

Han, Sangwoo,Lee, Jong Bum Elsevier 2018 Journal of industrial and engineering chemistry Vol.64 No.-

<P><B>Abstract</B></P> <P>Rolling circle transcription (RCT) has been studied for enhancing the delivery efficiency of therapeutic RNA by densely packing RNA strands with particle formation. This facile fabrication method has been successfully employed to generate RNA nanoballs containing functional short interference RNA. In addition, the nanoballs produced by RCT showed high stability from the nuclease degradation. With these advantages, using biotin-labeled ribonucleoside triphosphate (rNTP), target specific and non-toxic bubble RNA nanoball (BNB) was synthesized. To achieve tumor-targeting, epidermal growth factor receptor antibody (EGFR Ab) was used to target the tumor cells by labeling the target ligands with biotin–avidin interaction. Target gene silencing by EGFR Ab-labeled RNA nanoball was confirmed <I>in vitro</I>.

Sangwoo Han(한상우),Jongsun Kim(김종선) 대한전자공학회 2012 전자공학회논문지 Vol.49 No.10

본 논문에서는 다이나믹 주파수 스케일링 (DFS) 카운터를 사용하여 코오스, 파인 조정 기능을 갖는 CMOS 듀티 사이클 보정회로를 제시한다. DFS 카운터는 디지털-아날로그 컨버터의 비트 스위칭 글리치를 감소시키기 때문에 제안하는 CMOS 듀티사이클 보정회로의 듀티 보정 범위를 증가시키고 지터 특성을 개선한다. 제안하는 회로는 0.18-㎛ CMOS 공정을 이용하여 설계되었다. 0.5-1.5GHz의 넓은 동작 주파수와 25-75%의 넓은 듀티 사이클 보정 범위 내에서 측정된 최대 출력 듀티 사이클 에러는 ±1.1%이다. This paper presents a mixed-mode CMOS duty-cycle corrector (DCC) circuit that has a dynamic frequency scaling (DFS) counter and coarse and fine tuning adjustments. A higher duty-cycle correction accuracy and smaller jitter have been achieved by utilizing the DFS counter that reduces the bit-switching glitch effect of a digital to analog converter (DAC). The proposed circuit has been designed using a 0.18-㎛ CMOS process. The measured duty cycle error is less than ±1.1% for a wide input duty-cycle range of 25-75% over a wide freqeuncy range of 0.5-1.5 GHz.

Han, Sangwoo,Lim, Jongtae,Kim, Jongsun The Institute of Electronics and Information Engin 2016 Journal of semiconductor technology and science Vol.16 No.1

A new area-efficient multi-phase clock frequency multiplier is presented. The proposed fractional-ratio frequency multiplying DLL (FFMDLL) is implemented in a 65 nm CMOS process and occupies an active area of just $0.01mm^2$. The proposed FFMDLL provides 8-phase output clocks and achieves a frequency range of 0.6-1.0 GHz with programmable multiplication ratios of N/M, where N = 4, 5, 8, 10 and M = 1, 2, 3. It achieves an effective peak-to-peak jitter of 5 ps and dissipates 3.4 mW from a 1.0 V supply at 1 GHz.

SangWoo Han,Inha Hwang,Seung Min Kim,Young Soon Yang,SangWon Ha,Jeong Ho Han,Tae Hwan Park 대한직업환경의학회 2016 대한직업환경의학회지 Vol.28 No.-

Background: Agent Orange (AO) is the code name for one of the herbicides and defoliants used in the Vietnam War. Studies conducted thus far show a significant correlation between AO and the occurrence of cardiovascular diseases. But there is little data on the association between AO and stroke, and limited studies have targeted patient groups exposed to AO. Method: Bohun medical center Institutional Review Board (IRB) approved the study. (ID: 341) We studied patients with acute ischemic stroke within 7 days of onset in VHS medical center and 4 other general hospitals. Among them, 91 consecutive patients with previous exposure to AO were evaluated. For controlled group, 288 patients with no history of AO exposure were chosen. Result: There were 49 (44.0 %) DM patient with a higher frequency in the exposure group (93 (32.3 %) in control P = 0.045). There were 6 (6.6 %) hyperlipidemia in exposure group and 69 (24.0 %) in control. (P < 0.002). Small vessel occlusion was the most common subtype (36, 39.6 %) in exposure group but in control group, the large artery atherosclesosis was (120, 41.7 %) (P = 0.014). The NIHSS of the exposure group on admission showed lower scores (median values, 2 and 4, respectively; P = 0. 003). The median mRS was 1 for the exposure group and 2 for the control group, at discharge and after 3 months. After 3 months of discharge, 55 (60.4 %) in the exposure group and 171 (59.4 %) in the control group showed below mRS 1 (P = 0.001). Conclusion: This study targeted patients who are Vietnam veteran. There is some difference in vascular risk factors and clinical manifestations suggest AO exposure has contributed to a certain extent to the stroke.

In-Service Monitoring of Stator-Slot Magnetic Wedge Condition for Induction Motors

Han, Sangwoo,Jung, Junyeong,Lee, Kun Wang,Lee, Sang Bin,Nandi, Subhasis,Kim, Byunghwan,Kang, Byunghee [Institute of Electrical and Electronic Engineers] 2016 IEEE transactions on industry applications Vol.52 No.4

<P>Stator-slot magnetic wedges are used instead of conventional epoxy glass wedges in large, high-output induction motors since the motor efficiency and power factor can be improved. However, cases of loose or missing magnetic wedges due to their weak mechanical strength have recently been increasingly reported. Although missing wedges can deteriorate motor performance and reliability, there is currently no test method accepted in the field for wedge quality assessment other than offline, disassembled visual inspection. In this paper, a new in-service method for monitoring the magnetic wedge condition in induction motors based on the negative-sequence information is proposed. The new method is developed based on the analysis of the dynamic model of the induction motor with missing magnetic slot wedges, derived in this paper. The proposed method is verified on a finite-element (FE) model of a 6.6-kV, 1850-kW induction motor. It is also verified experimentally on a 6.6-kV, 220-kW induction motor operating in the field with missing wedges (before and after rewedging), and on a 380-V, 5.5-kW induction motor with custom-built, removable magnetic wedges. It is shown that the proposed method can provide online detection of missing magnetic wedges, which can help reduce maintenance costs and risk of degradation in motor performance.</P>

Back-projection imaging of small earthquake ruptures using the data from Gyeongju High-Density Broadband Seismic Network

Sangwoo Han,YoungHee Kim 대한지질학회 2021 대한지질학회 학술대회 Vol.2021 No.10

Back-projection imaging of the earthquake rupture process has provided critical insights on the kinematics of large earthquakes. As the coverage of seismic stations rapidly increases in recent years, there is a growing potential to apply the technique to smaller earthquakes to probe their spatio-temporal rupture complexity. We here use local P-wave data from Gyeongju High-density Broadband Seismic Network (GHBSN) to illuminate the rupture process at scales where the event has a rupture length of a few hundred meters. The GHBSN consists of 200 seismometers covering the epicenter region of 2016 ML 5.8 Gyeongju earthquake and has recorded eight earthquakes of ML 2.0 or higher in 2018-2021 at/near the fault system. Prior to the back-projection imaging of the local event, we perform correction of sensor orientation and L-Q-T ray-based coordinate transformation to probe high-frequency contents of L component which aligns in the direction of P-wave propagation. To better constrain earthquake rupture kinematics such as direction, length, and duration from the imaging results, we track the depth of maximum intensity for each horizontal grid cell. The reliability of the imaging results is assessed by numerical tests by producing synthetic waveforms combining multiple sources aligned along the direction of strike at short regular time intervals (i.e., rupture). The back-projection results of 2019 ML 2.9 earthquake shows a unilateral slip toward the southwest of its epicenter along the strike direction (N36°E). The length of the fault where the seismic energy released is within 200 m, up to a few tens of milliseconds.
