본 연구는 초등학교 3학년 읽기 학습부진 학생에게 일대일 어휘 중재를 실시한 사례 연구로, 사전검사, 진전도 3차, 사후검사의 5가지 검사에서 나타난 학생들의 전체 어휘 검사 점수, 그리고 하위 영역인 명시적 정의, 상황적 맥락, 형태소 분석 점수가 어떻게 변화하는지 확인 함으로써 추후 중재 연구에 기초 자료를 제공하고자 하는 목적을 가진다. 이를 위하여 2021년 5월부터 7월까지 경기도 S 시 소재 3학년 읽기 학습부진 학생 8명을 대상으로 15회기의 어휘 집중 중재와 지속적인 진전도 모니터링을 실시하였으며, 학생들의 검사 총점과 하위 영역별 원점수, t 점수를 그래프로 시각화하였다. 어휘 영역 사후검사 원점수는 사전검사에 비해 5점에서 24점 사이의 향상을 보였으며, 학생별 편차는 있었지만 명시적 정의, 상황적 맥락, 형태소 분석의 하위 영역 점수도 향상하였다. 또한, 학생을 직접 지도한 강사의 보고를 결과와 함께 제시하여 점수 변화의 원인과 맥락을 설명하였다. 본 연구의 결과를 토대로 초등학교 3학년 어휘 집중 중재의 효과적 방안과 어휘 하위영역별 성취, 지속적인 교육과정 중심 측정의 필요성에 대해 논의하였다. The present study is a case study of one-on-one vocabulary intervention for students with reading difficulties in the third grade of elementary school, and aims to provide basic data for future intervention by checking the students' overall vocabulary test scores and the scores of the sub-areas of explicit definition, situational context, and morpheme analysis scores. From May to July 2021, intensive vocabulary intervention and continuous progress monitoring were conducted for eight third-grade students with reading difficulties in S city, Gyeonggi-do. Students' total score and t-score for total vocabulary and for the sub-areas were visualized as graphs. The original score of the vocabulary area post-test showed an improvement of 5 to 24 points compared to the pre-test, and although there were variations by student, the scores of the sub-areas of explicit definition, contextual context, and morpheme analysis also improved. The report of the instructor who taught students was presented with the results to explain the cause and context of the change in scores. Based on the results of this study, the need for effective vocabulary intervention in the third grade of elementary school, achievement by vocabulary sub-area, and continuous curriculum-based measurement were discussed.

Lee, Dongil,Kim, Yong-Hun,Lee, Daewoong,Kim, Lee-Sup IEEE 2018 IEEE transactions on circuits and systems. a publi Vol.65 No.11

<P>This brief presents a 0.65-V power noise tolerant source-synchronous injection-locked receiver with 13.4 dB channel loss compensation. To meet the 1UI timing constraint for the decision feedback equalizer in low supply, SR latches are removed in the feedback path and return to zero recovered data is used for equalization. Additionally, a power noise sensitivity of low supply is relieved by current and pMOS body bias control techniques of an oscillator. The test core fabricated in 65-nm CMOS process achieves 11.2 Gb/s with 0.303 pJ/bit FOM compensating 13.4 dB channel loss at 5.6 GHz.</P>

A 21%-Jitter-Improved Self-Aligned Dividerless Injection-Locked PLL With a VCO Control Voltage Ripple-Compensated Phase Detector

Lee, Dongil,Lee, Taeho,Kim, Young-Ju,Kim, Lee-Sup IEEE 2016 IEEE transactions on circuits and systems. a publi Vol.63 No.8

<P>This brief presents a 2-GHz dividerless injectionlocked phase-locked loop (PLL) (ILPLL) with a voltage-controlled oscillator (VCO) control voltage ripple-compensated phase detector (PD) (RICPD). The proposed lock detector (LD) can detect not only the frequency difference between VCO frequency and target frequency but also the coarse phase position. With the help of the LD, the RICPD has a simple architecture using AND gates, relieving mismatches in the PD and charge pump. Additionally, the RICPD improves the performance of phase noise by a ripple compensation technique and solves an UP/DN pulse mismatch problem of PLL with a simple structure. As a result, the proposed ILPLL improves jitter performance by 21% (471-fs integrated jitter from 1 kHz to 40 MHz). The test core fabricated in a 65-nm CMOS process consumes 6.2 mW.</P>

Cystic Lesions of the Gastrointestinal Tract: Multimodality Imaging with Pathologic Correlations

Lee, Jongmee,Park, Cheol Min,Kim, Kyeong Ah,Lee, Chang Hee,Choi, Jae Woong,Shin, Bong Kyung,Lee, Soon Jin,Choi, Dongil,Jang, Kee-Taek The Korean Society of Radiology 2010 KOREAN JOURNAL OF RADIOLOGY Vol.11 No.4

<P>The cystic lesions of the gastrointestinal (GI) tract demonstrate the various pathologic findings. Some lesions may present a diagnostic challenge because of non-specific imaging features; however, other lesions are easily diagnosed using characteristic radiologic features and anatomic locations. Cystic masses from the GI tract can be divided into several categories: congenital lesions, neoplastic lesions (cystic neoplasms, cystic degeneration of solid neoplasms), and other miscellaneous lesions. In this pictorial review, we describe the pathologic findings of various cystic lesions of the GI tract as well as the radiologic features of GI cystic lesions from several imaging modalities including a barium study, transabdominal ultrasound (US), computed tomography (CT), and magnetic resonance (MR) imaging.</P>

Is there any clinical or radiologic feature as a preoperative marker for differentiating mass-forming pancreatitis from early-stage pancreatic adenocarcinoma?

Lee, Hyuk,Lee, Jong Kyun,Kang, Seok Seon,Choi, Dongil,Jang, Kee-Tack,Kim, Jeong Hwan,Lee, Kyu Taek,Paik, Seung Woon,Yoo, Byung Chul,Rhee, Jong Chul G. Thieme 2007 Hepato-gastroenterology Vol.54 No.79

<P>BACKGROUND/AIMS: The differential diagnosis of early-stage pancreatic cancer and mass-forming pancreatitis is still unsettled. The purpose of the present study was to define the differential feature of focal mass-forming pancreatitis and malignant mass using aspects of clinical, laboratory and imaging features on pancreatogram or computed tomography (CT). METHODOLOGY: Between April 1995 and May 2003, 15 patients confirmed as inflammatory mass after surgical resection for pancreatic mass and 21 patients with early-stage pancreatic adenocarcinoma among the patients diagnosed as pancreatic malignancy were included in our study. Hospital records, laboratory results, findings of imaging studies and pathological findings were reviewed retrospectively. RESULTS: Regarding the clinical characteristics, the history of previous pancreatitis was distinguished in group with mass-forming pancreatitis. Incidence of jaundice was higher in the group with adenocarcinoma than in the mass-forming pancreatitis group. For laboratory results, CA19-9 level and alkaline phosphatase level were significantly elevated in the malignant group. Findings such as hyperattenuation on portal venous phase of CT scans and gradual tapering stricture on pancreatogram were differential diagnostic markers between the two groups. A portion of patients with mass-forming pancreatitis demonstrated the pathologic characteristics of autoimmune pancreatitis. CONCLUSIONS: Our 9-year experience suggests that imaging findings such as attenuation pattern on the delayed phase of CT scan and tapering pattern of pancreatic ductal stricture on pancreatogram can help to differentiate mass-forming pancreatitis from early-stage pancreatic adenocarcinoma.</P>

A Vertically Integrated Junctionless Nanowire Transistor

Lee, Byung-Hyun,Hur, Jae,Kang, Min-Ho,Bang, Tewook,Ahn, Dae-Chul,Lee, Dongil,Kim, Kwang-Hee,Choi, Yang-Kyu American Chemical Society 2016 NANO LETTERS Vol.16 No.3

<P>A vertically integrated junctionless field-effect transistor (VJ-FET), which is composed of vertically stacked multiple silicon nanowires (SiNWs) with a gate-all-around (GAA) structure, is demonstrated on a bulk silicon wafer for the first time. The proposed VJ-FET mitigates the issues of variability and fabrication complexity that are encountered in the vertically integrated multi-NW FET (VM-FET) based on an identical structure in which the VM-FET, as recently reported, harnesses a source and drain (S/D) junction for its operation and is thus based on the inversion mode. Variability is alleviated by bulk conduction in a junctionless FET (JL-FET), where current flows through the core of the SiNW, whereas it is not mitigated by surface conduction in an inversion mode FET (IM-FET), where current flows via the surface of the SiNW. The fabrication complexity is reduced by the inherent JL structure of the JL-FET because S/D formation is not required. In contrast, it is very difficult to dope the S/D when it is positioned at each floor of a tall SiNW with greater uniformity and with less damage to the crystalline structure of the SiNW in a VM-FET. Moreover, when the proposed VJ-FET is used as nonvolatile flash memory, the endurance and retention characteristics are improved due to the above-mentioned bulk conduction.</P>

A Study on Geogoð in Old English Poetry : Beowulf 535-538 『베오울프』 535-538

Lee, Dongill 중세영문학연구회 2002 중세영문학 Vol.10 No.2

'청년, 소년, 젊은이, 어린시절'을 뜻하는 고대영어 Geogoð는 고대영시에서 매우 광범위하게 쓰이며 특히 『베오울프』에서는 시의 주제인 영웅주의 도덕관과 맞물려 중대한 문맥상의 의미를 형성한다. 대부분의 학자들은 베오울프와 운페르드 사이에 벌어지는 설전(flyting)에서 베오울프가 언급한 Geogoð를 예로 들어 베오울프가 어린시절 성급한 판단하에 브레카와 무모한 수영시합을 시도했다고 보고 있다. 이러한 해석은 Geogoð에 대한 문맥상의의미를 도외시한 결과이며 동시에 시의 주된 요소인 영웅주의 도덕관을 고려하지 않은 편협한 견해에 지나지 않는다. Geogoð는 『베오울프』 외에도 많은 고대영시와 산문에서 부정적인 의미와 더불어 긍정적인 의미로 쓰이고 있다. 특히 『베오울프』에서는 부정적인 의미보다는 긍정적인 의미로 더 많이 쓰이고 있다. 『베오울프』의 주된 인물들은 자신들의 영웅적 업적을 과시할 때 주저없이 Geogoð를 언급하고 있다. 특히 운폐르드와의 설전 부분에서 베오울프가 언급한 Geogoð는 베오울프 자신의 미숙한 판단과 성급함을 인정했다기보다는 자신의 영웅적 기질이 남보다 앞서 어린 나이에 발휘됐음을 과시하고 있으며 동시에 뛰어난 업적을 어린 나이에 성취했음을 자랑스럽게 알리고 있는 것이다. 이런 맥락에서 Geogoð는 영웅주의 도덕관을 규명하는 중요한 어휘로 자리잡게 된다.
