The purpose of this study is to investigate the effect of instructional consultation on strengthening teaching competencies of professors by providing them with instructional consultation according to the degree of participation. The main research problem is to clarify the effect of instructional consultation in universities on professors’ awareness of lecture problems, lecture design, and lecture practice in detail. For this, instructional consultation was conducted for 24 university professors throughout a semester. Specifically, the instructional consultation was divided into different areas such as professors, subjects of lecture, and students, and self-reports, recording materials, and students’ satisfaction were analyzed. Additionally, problems to be improved were drawn based on the evaluation results of teaching approaches according to the degree of participation of instructional consultation, and the structure of lecture was divided into introduction, development, and conclusion to analyze the details by each stage, based on which advanced teaching strategy was suggested. As a result of the action research, it was revealed that instructional consultation had positive effects on some components of professors’ teaching competencies such as self-examination of their own lecture, cooperation with fellow professors, lecture design and practice, and restructuring of lecture. Furthermore, instructional consultation in universities helped professors face their own lecture and realize its problems, and advanced alternatives for lecture design and practice were explored through self-examination according to the realization of problems and cooperative interaction with consultants. In addition, anxiety about recording the lecture and skepticism felt during the process of planning and practicing lecture turned into confidence after going through cooperative interaction with consultants. Based on the results, the efforts of the professors who participated in the instructional consultation to improve their own lecture had positive effects on strengthening their teaching competencies. 본 연구의 목적은 교수자들에게 대학 수업컨설팅을 실행하여 참여정도에 따라 교수역량강화에 미치는 영향을 살펴보는데 있다. 주요 연구문제는 대학 수업컨설팅이 교수자들의 수업 문제점 인식, 수업설계, 수업실행에 어떠한 영향을 미치는가를 상세히 밝히는 것이다. 이를 위해 24인의 대학 교수자들을 대상으로 한 학기에 걸쳐 대학 수업컨설팅을 실시하였다. 구체적으로 대학 수업컨설팅의 영역을 교수자, 수업내용, 학습자로 구분하여 수업 자가진단지, 수업 녹화자료, 학습자 수업만족도를 분석하였다. 또한 대학 수업컨설팅의 참여정도에 따른 교수접근방법의 진단결과를 근거로 개선점을 도출하였고, 수업의 구조를 도입, 전개, 정리 단계로 나누어 영역별로 내용을 분석한 후 이를 근거로 발전적인 수업전략을 제안하였다. 실행연구 결과 대학 수업컨설팅이 교수자의 교수역량 구성요소 중 자기수업성찰과 동료교수협력, 수업설계와 실천, 강의 재구성 역량에 긍정적 영향을 미치는 것으로 나타났다. 또한 대학 수업컨설팅은 교수자로 하여금 자기수업에 직면하게 함으로써 수업문제점 인식에 도움을 주었고, 문제점 인식에 따른 자기 성찰 및 컨설턴트와의 협력적 상호작용을 통해 수업설계와 수업실행의 발전적 대안을 모색하였다. 뿐만 아니라 수업녹화에 대한 불안감과 수업계획 및 실천과정에서 느꼈던 회의감은 컨설턴트와의 협력적 상호작용을 통해 자신감으로 변화되었다. 이상의 결과를 종합할 때 대학 수업컨설팅 활동에 참여한 교수자들의 자기수업개선의 노력은 교수역량강화에 긍정적인 영향을 주었다고 볼 수 있다.

Wireless Body Area Networks is an environment that provides an appropriate service remotely by collecting user's biometric information. With the growing importance of sensor, WBAN also attracts extensive attention. Since WBAN is representatively used in the medical field, it can be directly related to the patient's life. Hence security is very important in WBAN. Mutual authentication between the client and the application provider is essential. And efficiency is also important because a used device is limited to computation cost. In this reason, ID-based anonymous authentication scheme in WBAN has been intensively studied. We show that the recent research result of Wu et al. which is about the ID-based anonymous authentication scheme is vulnerable to impersonation attack. And we propose a new ID-based anonymous authentication scheme that is secure against the attacks discovered in the existing schemes. Compared to the existing schemes, the computation cost of our scheme is improved by 30.6% and 7.3%.

The effects of Ru deposition temperature and post-annealing conditions on the interfacial adhesion energies of atomic layer deposited (ALD) Ru diffusion barrier layer and Cu thin films for the advanced Cu interconnects applications were systematically investigated. The initial interfacial adhesion energies were 8.55, 9.37, 8.96 J/m2 for the sample deposited at 225, 270, and 310oC, respectively, which are closely related to the similar microstructures and resistivities of Ru films for ALD Ru deposition temperature variations. And the interfacial adhesion energies showed the relatively stable high values over 7.59 J/m2 until 250h during post-annealing at 200oC, while dramatically decreased to 1.40 J/m2 after 500 h. The X-ray photoelectron spectroscopy Cu 2p peak separation analysis showed that there exists good correlation between the interfacial adhesion energy and the interfacial CuO formation. Therefore, ALD Ru seems to be a promising diffusion barrier candidate with reliable interfacial reliability for advanced Cu interconnects. 차세대 초미세 Cu 배선 적용을 위한 원자층증착법(atomic layer deposition, ALD)을 이용하여 증착된 Ru확산방지층과 Cu 박막 사이의 계면 신뢰성을 평가하기 위해, Ru 공정온도 및 200oC 후속 열처리 시간에 따라 4점굽힘시험으로 정량적인 계면접착에너지를 평가하였고, 박리계면을 분석하였다. 225, 270, 310oC 세 가지 ALD Ru 공정온도에 따른계면접착에너지는 각각 8.55, 9.37, 8.96 J/m2로 유사한 값을 보였는데, 이는 증착온도 변화에 따라 Ru 결정립 크기 등 미세조직 및 비저항의 차이가 적어서, 계면 특성도 거의 차이가 없는 것으로 판단된다. 225oC의 공정온도에서 증착된 Ru 박막의 계면접착에너지는 200oC 후속 열처리시 250시간까지는 7.59 J/m2 이상으로 유지되었으나, 500시간 후에는 1.40 J/ m2로 급격히 감소하였다. 박리계면에 대한 X-선 광전자 분광기 분석 결과, 500시간 후 Cu 계면 산화로 인하여 계면접착에너지가 감소한 것으로 확인되었다. 따라서 ALD Ru 박막은 계면신뢰성이 양호한 차세대 Cu 배선용 확산방지층 후보가 된다고 판단된다.

This study analyzed past drought characteristics based on the observed rainfall data and performed a long-term outlook for future extreme droughts using Representative Concentration Pathways 8.5 (RCP 8.5) climate change scenarios. Standardized Precipitation Index (SPI) used duration of 1, 3, 6, 9 and 12 months, a meteorological drought index, was applied for quantitative drought analysis. A single long-term time series was constructed by combining daily rainfall observation data and RCP scenario. The constructed data was used as SPI input factors for each different duration. For the analysis of meteorological drought observed relatively long-term since 1954 in Korea, 12 rainfall stations were selected and applied 10 general circulation models (GCM) at the same point. In order to analyze drought characteristics according to climate change, trend analysis and clustering were performed. For non-stationary frequency analysis using sampling technique, we adopted the technique DEMC that combines Bayesian-based differential evolution (“DE”) and Markov chain Monte Carlo (“MCMC”). A non-stationary drought frequency analysis was used to derive Severity-Duration-Frequency (SDF) curves for the 12 locations. A quantitative outlook for future droughts was carried out by deriving SDF curves with long-term hydrologic data assuming non-stationarity, and by quantitatively identifying potential drought risks. As a result of performing cluster analysis to identify the spatial characteristics, it was analyzed that there is a high risk of drought in the future in Jeonju, Gwangju, Yeosun, Mokpo, and Chupyeongryeong except Jeju corresponding to Zone 1-2, 2, and 3-2. They could be efficiently utilized in future drought management policies 본 연구는 한반도의 관측 강우자료를 기반으로 하여 과거의 가뭄 특성을 파악함과 동시에 RCP 8.5 기후변화 시나리오를 활용한 장래 발생 가능한 극치 가뭄에 대한 장기전망을 수행하였다. 정량적인 가뭄 분석을 위해 기상학적 가뭄지수인 표준강수지수(Standardized Precipitation Index, SPI)를 적용하였으며 일단위 강우 관측 자료 및 RCP 시나리오를 단일한 장기 시계열 자료로 구축하여 1, 3, 6, 9, 12개월 지속기간의 SPI 입력인자로 활용하였다. 한반도의 지역별 가뭄특성 분석을 위한 대상 강우관측소는 1954년 시점부터 강우 자료를 보유하고 있는 12개 관측 지점을 선정하였으며, 동일 지점의 10개 GCM(General Circulation Model)을 적용하였다. 기후변화에 따른 가뭄 특성 변화 분석을 위해 강우발생일수와 총강수량에 대한 12개 강우관측소별 추세 변동 분석 및 군집화를 수행하였다. 샘플링 기법을 활용한 비정상성 빈도분석을 위해 베이지안 기반의 DE(Differential Evolution)와 MCMC(Markov Chain Monte Carlo)를 결합한 DEMC 기법을 채택하였고, 비정상성 가뭄빈도해석을 통하여 12개 지점별 SDF(Severity-Duration-Frequency) 곡선을 유도하였다. 비정상성을 가정한 장기 수문자료를 보유한 지점들의 SDF 곡선 산정을 통해 미래의 가뭄에 대한 정량적인 전망을 수행하였다. 장기시계열 자료를 보유한 12개 지점의 군집분석을 수행한 결과 Zone 1-2, 2, 3-2에 해당하는 제주를 제외한 전주, 광주, 여순, 목포, 추풍령 등에서 장래에 가뭄발생 위험이 높은 것으로 분석되었다. 장래 발생 가능한 가뭄 위험성을 정량적으로 파악함으로써 미래 가뭄관리 정책에 충분히 활용될 수 있을 것으로 기대된다.

Effects of Shear Rate and Consolidation Time on Undrained Behavior of Natural Sedimentary Clay

정민수,채종길,시부야 사토루 한국지반공학회 2009 한국지반공학회논문집 Vol.25 No.3

Effects of shear rate and consolidation time on undrained shear behavior of seabed Holocene clay at Kobe airport site were examined in a series of triaxial compression and extension tests performed using different rate of axial straining. A comparative compression test in which the axial strain rate was changed in steps was also carried out. Similar tests were performed in constant-volume direct shear box (DSB) test. It was found that the undrained strength increased with not only the shear rate but also the consolidation period. Isotach properties seemed to be a key to govern the undrained shear behavior.

An animal model with experimental uremia is an a important research tool for the study of sequence of pathological events taking place in uremic syndrome. A number of animal models and methods for the induction of chronic uremia have been published. The present study is designed to estabilish usefullness of a new method for the induction of chronic uremia in the rat. This method consist of unilateral destruction of most of the renal cortex by burns and contralateral nephrectomy. To investigate the results of massive renal ablation by this method, we measured serially blood pressure, body weight, BUN, serum creatinine, creatinine clearance, rate and examined renal histology. The results were as follows : 1) Surgical mortality rate was 5% and postoperative mortality of experimental group was 30.8% during 15 weeks of postoperative period. 2) Blood pressure of experimental group was significantly higher than control group after renal ablation(p<0.01). 3) Experimental group showed lower body weight gain than control group(p<0.01). 4) BUN and serum creatinine values increased continuously after renal ablation. However, those of control group were not changed. 5) Creatinine clearence rate of experimental group decreased significantly after renal ablation(p<0.01). 6) Weight of remnant kidney in experimental group was significantly higher than left kidney of control group(p<0.01). 7) Histologically, focal and segmental glomerular sclerosis, mesangeal proliferation, interstitial fibrosis and tubular atrophy appeared in the kidney of most experimental group 15 weeks after renal ablation. In conclusion, experimental rat group shows remarkable uremic appearance 7-11 weeks after renal ablation. This suggests that the unilateral renal cortical electrocoagulation and contralateral nephrectomy was a useful method for inducing experimental CRF rat model.
