본 연구의 목적은 공과대학 재학 중 학사경고를 받은 학생 그리고 학사경고를 경험하지 않은 일반 학생의 동기와 학습전략의 차이를 살펴보는 데 있다. 본 연구의 대상은 서울 소재 A대학 공과대학 학생으로 이들은 교수학습개발센터에서 학습전략 검사에 참여하였다. 본 연구 대상은 총 553명이며 이 가운데 학사경고 학생은 22명, 일반학생은 531명이다. 본 연구의 목적을 달성하기 위하여 표준화된 검사인 한국 가이던스의 MLST(Multi-dimensional Learning Strategy test) 학습전략 검사지를 사용하였다. 학사경고를 받은 학생과 그렇지 않은 학생, 두 집단 간 동기와 학습전략을 비교 분석하기 위하여 t-test를 실시하였다. 그 결과, 학사경고를 받은 학생의 경쟁 동기 점수가 일반 학생들 보다 낮았으며 학사경고 학생들의 시간 관리와 노트필기 요인의 점수가 일반 대학생 보다 낮았다.

정보통신 분야의 기술적 진보를 통해 다양한 종류의 스마트 기기들이 등장하고 활용되면서 사람들의 사용 행태와 환경에도 많은 변화가 발생했다. 이러한 변화는 학습 환경에서도 적용되어, 다양한 스마트 기기들이 학습 환경에 등장하고 있으며 학습자의 학습 행동 양식 또한 달라지고 있다. 이 연구에서는 학습 매체 및 필기 도구로 활용되는 스마트 기기 중 최근 등장한 디지털 펜과 태블릿PC를 중심으로, 이를 활용한 디지털 필기 행동에 대한 학습자의 인식을 알아보고자 한다. 기대 일치 모형을 활용하여, 대학생들의 태블릿PC와 디지털 펜에 대한 사전 기대 및 이후 사용 경험과의 비교를 통해 기대 (불)일치 및 (불)만족 요인에 대한 연구를 수행하였다. 이를 위해 국내 C 대학교의 학생들을 대상으로 개방형 설문을 진행하고, 해당 응답을 질적 내용 분석을 통해 분석하여 네 가지 기대 일치 및 만족 요인과 세 가지 기대 불일치 및 불만족 요인을 도출하였다. 이후 결과를 바탕으로 학술적 및 교육적 시사점을 제공하였다.

Vietnamese scholars contend that they have developed Southeast Asian studies viewing Southeast Asia as both a geographical entity with a long history and cultural tradition and a strategic region for modern development. This study has traced the construction of Southeast Asian studies as an academic discipline in Vietnam through the studies and arguments of Vietnamese scholars. It has put primary focus on the institutionalization of Southeast Asian studies, taking note of the assessment and perceptions of Vietnamese scholars. It also looked into the construction and limitations of Southeast Asian studies in Vietnam, which advocates Southeast Asian Studies as interdisciplinary area studies, with stressing of the origin of indigenous studies. The major contents of this study include: First, a historic overview of the institutionalization of Southeast Asian studies centering on research institutions of Southeast Asian studies in Vietnam, Second, the perceptions of Southeast Asian studies inside Vietnam and the inside evaluation of the effort to indigenize Southeast Asian studies. This study took note of Vietnamese scholars' perceptions and assessment of Southeast Asian studies performed by outsiders, primarily by Western scholars; the perceptions and evaluation of Southeast Asian studies conducted by Southeast Asian insiders; and the perceptions and evaluation of the origin of Southeast Asian studies indigenous to Vietnam. Last, it examined the construction and limitations of Southeast Asian studies in Vietnam, which advocates the studies as interdisciplinary regional studies.

본 연구는 통화정책 전달경로 중 은행자본경로와 위험추구경로가 국내은행에도 작동하는지에 대해 실증분석하였다. 이를 위해 확장적 통화정책이 은행의 예대금리차, BIS비율, 위험가중자산비율 및 대출 등에 미치는 영향을 분석하였다. 실증분석은 기존 연구에서 통화정책 영향분석에 많이 사용된 Uhlig (2005)의 부호제약 SVAR(Structural VAR) 모형을 토대로 실시하였다. 본 연구는 실증분석을 통해 국내외 기존 연구 결과와 유사하게 국내은행에서도 은행자본경로 및 위험추구경로가 작동하는 것을 확인하였다. 확장적 통화충격에 대해 국내은행의 예대금리차는 확대되었으며, 자기자본비율은 개선되었고, 이후 총대출이 증가하는 것으로 분석되었다. 이는 은행자본경로가 작동함을 의미한다. 또한, 실질콜금리에 대한 확장적 통화충격에 대해 위험가중자산비율이 증가하는 것으로 분석되었다. 이는 위험추구경로가 작동함을 의미한다. 본 연구의 시사점은 다음과 같다. 확장적 통화정책 지속 시 은행자본경로 작동으로 단기적으로 은행 건전성과 수익성이 개선되는 효과도 있으나, 위험추구경로 작동으로 중장기적으로 은행의 위험추구(risk-taking) 행위가 심화되어 은행의 실질적 건전성에 악영향을 줄 수 있다. 이에 따라 금융당국은 확장적 통화정책 지속 시 편중리스크 발생 및 시스템리스크 증가 등에 대한 선제적인 모니터링 및 감독을 강화할 필요가 있다.

Free vibration of non-uniform embedded nanoplates based on classical (Kirchhoff's) plate theory in conjunction with nonlocal elasticity theory has been studied. The nanoplate is assumed to be rested on two-parameter Winkler-Pasternak elastic foundation. Non-uniform material properties of nanoplates have been considered by taking linear as well as quadratic variations of Young's modulus and density along the space coordinates. Detailed analysis has been reported for all possible casesof such variations. Trial functions denoting transverse deflection of the plate are expressed in simple algebraic polynomial forms. Application of the present method converts the problem into generalised eigen value problem. The study aims to investigate the effects of non-uniform parameter, elastic foundation, nonlocal parameter, boundary condition, aspect ratio and length of nanoplates on the frequency parameters. Three-dimensional mode shapes for some of the boundary conditions have also been illustrated. One may note that present method is easier to handle any sets of boundary conditions at the edges.

This paper concerns with the application of e-based education methodology for people with disabilities targeting to empower them. Instead of the classic educational support such as extended time to take exams, a reader and/or scribe to assist with exams and note taking services, we suggest the use of new pedagogy-the science of educations integrating the state-of-the art. In this paper, we introduce the definition of disabilities for the people who does not fully understand what they means, first, and then possible implementing tools which can empower them with accomplishments. Most of the research in the field of pedagogy has tended to concentrate on the behavioral aspects of instructional sciences. Therefore we would like to point out that we concentrate on the aspects of instructional science particularly related with people with disabilities.

In this technical note, I report the analysis of electrochemical impedance data measured with potential sweeping. Even though the instruments for voltammetric impedance measurements have been developed for decades using different approaches, their applications are limited due to the lack of well-established protocols to easily analyze voltammetry data. To fill this gap, the singular point of the specific potential is considered that is only determined by the standard/formal potential and the transfer coefficient and is independent of the kinetics and experimental parameters (including revertability) of faradaic reactions. Taking the advantage of its inertness, I suggest an approach employing the singular point as a reference to obtain general electrochemical information. As all the concepts and methods are verified with numerical simulations, this technique is expected to be applied for complex reactions involving electrochemical and chemical reaction mechanisms.

The polishing of silicon wafers has an important role in semiconductor manufacturing. Generally, getting a flat surface such as a mirror is the purpose of the process. The wafer surface roughness is affected by many variables such as the characteristics of the carrier head unit, operation, speed, the pad and slurry temperature. Optimum process conditions for experimental temperature, pH value, down-force, slurry ratio are investigated, time is used as a fixed factor. This study carried out a series of experiments at varying platen, chuck rpm and oscillation cpm taking particular note of the difference between the rpm and the affect it has on the surface roughness. In this experiment determine the optimum conditions for polishing silicone wafers.

Let ${X_n : n = 1,2,\cdots}$ be a sequence of pairwise independent identically distributed random vectors taking values in a separable Hilbert space H such that $E \Vert X_1 \Vert = \infty$. Let $S_n = X_1 + X_2 + \cdots + X_n$ and for any real $\alpha$ with $0 < \alpha < 1$ define a sequence ${\gamma_n(\alpha)}$ as $\gamma_n(\alpha) = inf {r : P(\Vert S_n \Vert \leq r) \geq \alpha}$. Then $$ lim_{n \to \infty} sup \Vert S_n \Vert/\gamma_n(\alpha) = \infty $$ holds. This is a generalization of Vvedenskaya[2].

This paper describes a study of the conditions and reasons that elementary school children avoid the namul provided in school meals. This study was conducted with a sample of 751 fifth-grade elementary school children and 49 nutritionists working in elementary schools. Nutritionists felt the need to develop new recipes, and were taking note of leftovers in an effort to increase namul consumption. 47% of the students reported liking namul, and the majority of students who disliked namul reported that its taste was the reason that they disliked it. Nutritionists believed that the students avoided namul due to a lack in familiarity, as well as taste. However, students answered that they disliked namul not only due to its taste, but also due to its texture.
