본 논문은 현대중국어 ‘吗’의문문의 응답 방식을 분석하여 한국인 중국어 학습자가 ‘吗’의문문 형식의 질문에 대해 정확하게 응답할 수 있는 방법론을 모색하는 데 목적을 두었다. ‘吗’의문문의 기능과 구조는 중국어 초급단계에서 학습하는 과정으로 정확한 응답 방식의 숙지가 이루어지지 않는 경우 고급 학습 단계에서도 지속적인 문장 활용의 오류가 발생할 수 있다. ‘吗’의문문에 대한 구조와 기능에 대한 선행연구는 활발하게 이루어졌으나 ‘吗’의문문의 응답 방식의 연구는 많지 않다. 이에 본고에서는 ‘吗’의문문의 응답 방식을 형식의 측면인 통사론의 관점에서 다층적으로 분석하였다. 논문의 구성은 다음과 같다. 제1장은 서론으로서 문제 제기, 연구의 목적과 연구방법을 설명한다. 제2장은 한국과 중국에서 발행된 논문류와 단행본을 참조하여 기존의 중국어 ‘吗’의문문에 대한 연구를 고찰하고 한국어 판정의문문의 응답 방식 및 한국어 긍정표지 응답어인 ‘예’의 의미와 기능을 살펴본다. 제3장은 영화/드라마 극본 40편에서 ‘吗’의문문의 질문과 응답을 발췌하여 실제 ‘구어’에서 사용하는 ‘吗’의문문의 응답 방식을 분석하여 원어민의 응답 경향성을 파악한다. 제4장은 제3장에서 분류한 질문 유형에서 23문항의 질문을 선정하여 5개 그룹으로 나누어 1차 개방형(주관식) 설문조사, 2차 폐쇄형(객관식) 설문조사를 진행한다. 중국어 원어민(L1)의 응답 경향성을 분석하고 한국인 학습자(L2)의 응답을 고찰한 후 L1과 L2의 응답을 비교·분석하여 모어의 영향, 통사적 오류 사항을 파악한다. 제5장은 결론 부분으로 본론에서 논의하고 분석한 내용으로 얻어진 결과를 정리 기술한다. This study aims to rearrange the characteristics of the ways of answering various Chinese ‘ma-interrogative sentences’, so that the Korean students who learn Chinese as a foreign language can better understand. I made a precedent research on the syntactic structures and functional types of the ma-interrogative sentences, I further made a deep analysis on various ways of answering them. The three main functional types of ma-interrogative questions, i.e., information-request questions, confirmation questions and repeating questions can be distinguished by tracing the grammaticalization of the word ‘ma’(吗). This thesis analyses the ways of answering ma-interrogative sentences, and also compares the ways of answering with ‘是’(shì) or ‘对’(duì), or with ‘不是’(búshì) or ‘不对’( búduì), and other ways of answering. Some ma-interrogative sentences can be answered with ‘是’ or ‘对’, whereas others can not. Whether or not ma-interrogative sentences can be answered with ‘是’ or ‘对’ depends on their being the neutral questions or non-neutral questions. I analyzed the ways of answering ma-interrogative sentences extracted from movie and drama scripts. Based on this analysis, I surveyed the ways of answering ma-interrogative sentences from 100 people. The results of the analysis are as follows:- First, ‘是’ or ‘对’, ‘不是’ or ‘不对’ are not complete as answers to the neutral questions. Second, differences between neutral and non-neutral questions may vary depending on the language environment, context, etc. Third, as a result of syntactic analysis, I found out that there is a typical tendency of native speakers in answering ma-interrogative sentences. Fourth, the ways of answering negative questions are relatively complicated than those of answering positive questions. And it has been found that syntactic errors many Korean students make lie in the negative form of ma-interrogative sentences and ‘modal particle+ma’ form.

The large majority of the earthquake response studies that have considered yielding have used elasto-plastic hysteretic force-displacement relations for the structures. Deformations and stresses developed during major earthquake will exceed the elastic limit of the structural responses; hence, the structural response cannot be assumed to be linearly elastic, and the result predicted by an elastic analysis and the result predicted by an elastic analysis are not valid. This is the reason that nonlinear analysis is important in desigring of building to intensive earthquakes. In this paper, a type of yielding structure defined the elasto-plastic behavior is studied and obtain the maximum displacement response by using Wilson-θ method which is a ki0d of step-by-step direct integration methods, and ductility-restoring force relations. Herein, El Centro earthquake accelerations for 3 seconds ii used for the input loading.

Dynamic characteristics optimization of the tray of an avionics component installed in a helicopter
이종학 Graduate School, Yonsei University 2010 국내석사
Electronic equipment continues its relentless expansion into virtually every area associated with commercial, industrial, and military applications throughout the entire world. An avionics component that is one of electronic equipment is installed in a aircraft. This equipment is exposed to dynamic loads as vibration, shock, and acceleration. Especially, an avionics component installed in a helicopter is subjected to simultaneous sine and random base excitation. It is called sine on random vibration according to MIL-STD-810F, Method 514.5. In the past, isolators has been applied to avionics components for reducing vibration and shock without distinction. But, isolator applied to an avionics component installed in a helicopter amplify vibration magnitude, and damage to a chassis, circuit card assembly and isolator itself by resonance at low frequency sinusoidal vibration. The object of this paper is to investigate the dynamic characteristics of an avionics component installed in a helicopter and the structure dynamic modification of its tray plate without isolator using a finite element analysis and experiments. A selection of dynamic load for optimization is conducted by comparison of vibration, shock, and acceleration loads using vibration response spectrum and shock response spectrum. The FE-model was constructed using a simplified geometry and valid element types that effectively reflect the dynamic characteristics. The FE-model was verified by experimental modal analysis (EMA). Design parameters are extracted and selected to modify the structural dynamics using topology optimization, design of experiments (DOE). A prototype of modified model was constructed and its substitutability was evaluated using FEM and performance test.

AUTOSAR 기반 차량 시스템의 성능 최적화를 위한 러너블-태스크 매핑 규칙
자동차가 점차 전장화됨에 따라 차량용 소프트웨어의 크기와 복잡도가 크게 증가하고 있다. 이 때문에 차량용 소프트웨어의 개발에 소요되는 시간과 비용 또한 증가하여 유럽의 주요 자동차 회사들은 개발의 효율성을 높이고자 AUTOSAR(AUTomotive Open System ARchitecture) 표준을 제정하였다. AUTOSAR 표준은 차량용 소프트웨어의 아키텍처와 개발 과정을 정의한 표준으로써 현재 많은 자동차 회사들에서 이를 준수하여 제품을 개발하고 있다. AUTOSAR 표준에 따른 응용 소프트웨어는 소프트웨어 컴포넌트(software component) 단위로 모듈화되어 설계되며 각각의 소프트웨어 컴포넌트는 자신의 기능을 구현하는 러너블(runnable)을 1개 이상 갖는다. 개발자는 러너블을 동작시키기 위해 운영체제의 스케줄링 단위인 태스크에 매핑하는데, 러너블-태스크 매핑에 따라 시스템 오버헤드 발생량이 크게 달라지므로 이는 시스템 성능 측면에서 매우 중요한 작업이다. 본 학위 논문에서는 자율주행을 수행하는 타겟 응용의 성능 최적화를 위해 기존 연구에서 제안한 6개의 러너블-태스크 매핑 규칙을 적용하며, 추가적인 성능 향상을 위해 기존 규칙을 개선한 매핑 규칙을 제안한다. 제안된 규칙을 적용하여 매핑했을 때와 개발자가 임의로 매핑했을 때 타겟 응용의 성능을 실험을 통해 비교하며, Infineon 사의 AURIX 보드와 ETAS 사의 AUTOSAR 플랫폼 상에서 타겟 응용을 구현하여 실험하였다. 실험 결과 제안된 규칙을 적용하여 매핑했을 때 타겟 응용의 종단 간 응답 시간(end-to-end response time)이 개발자가 임의로 매핑했을 때의 기댓값보다 약 1.49배 짧은 것으로 확인되었다. As automobiles become increasingly electric, the size and complexity of automotive software is greatly increasing. As a result, the time and cost of developing automotive software has also increased, leading European automotive companies have established the AUTOSAR (Automotive Open System Architecture) standard to improve development efficiency. The AUTOSAR standard is the standard for the architecture and development process of automotive software. Application software according to the AUTOSAR standard is modularized in software components, and each software component has one or more runnables that implement its functions. The developer maps the runnables to the tasks, which is the scheduling unit of the operating system, in order to execute the runnable. Runnable-to-task mapping is very important process in terms of system performance, since the system overhead incurred greatly depends on the runnable-to-task mapping. In this thesis, I apply six runnable-to-task mapping rules proposed in the previous research to optimize the performance of the target application that performs autonomous driving, and propose mapping rules that improves the existing rules for further performance enhancement. I compare the performance of the target application when the runnables are mapped to the tasks according to the proposed mapping rules and when the developer arbitrarily mapped it. The target application is implemented on the Infineon AURIX board and ETAS AUTOSAR platform. Experimental results show that the end-to-end response time of the target application when mapped by applying the proposed rules is about 1.49 times shorter than the expected value when the developer arbitrarily mapped.

不規則振動理論에 근거한 地震荷重을 받는 多自由度系 構造物의 動的應答解析
When a structural system is subjected to earthquake ground motion, the maximum response(displacement,velocity,acceleration) of the structural system will be primarily obtained by the method of modal analysis. Also the response of the structural system will be obtained by the another method, a random vibration analysis, considering uncertainty of earthquake ground motion. There are two ways to obtain the response of the system subjected to earthquake ground motion in the random vibration analysis. Those are time domain approach and frequency domain approach. A frequency domain approach using power spectral density functions to describe excitation and response, and a transfer function to characterize the system, has proved to be very useful. Of particular interest among various quantities of response is the probability distribution or the mean and variance of the peak response over a service duration of the system. The probability distribution functions of the maximum absolute value of the process over a service duration of the system were defined by Davenport and Vanmarcke. In this study, the response of two-degree-of-freedom system subjected the earthquake ground motion is obtained by the method of modal analysis and the method of random vibration analysis within the elastic system. The earthquake ground motion is the accelerogram of the E1 Centro earthquake, 1940, N-S component composed of 2950 data of which time step is 0.01 second. And compare the responses obtained by the modal analysis with by the random vibration analysis using Davenport and Vanmarcke probability distribution functions of the maximum absolute value of the process over a service duration of the system.
