손다정(Son, Da-jung),장미정(Jang, Mi-jung) 중앙어문학회 2013 語文論集 Vol.56 No.-

이 연구는 학문 목적 한국어 쓰기 교육의 연구 경향을 분석하여 그 결과를 제시하고 이를 바탕으로 하여 앞으로의 연구에 시사점을 제안하는 데 목적이 있다. 한국어교육에 학문 목적 한국어교육 개념이 도입된 이후 현재까지 학문 목적 한국어교육 연구는 지속적으로 증가해 왔을 뿐만 아니라 그 범위도 넓어졌다. 이중에서도 쓰기 교육 연구가 특히 활발히 이루어졌다. 이는 학습자의 요구가 특히 높은 영역이기도 하거니와 학문 목적의 쓰기가 보이는 일반 목적의 쓰기와 다른 특징들 때문이다. 주제별로 연구 경향을 분석한 결과 교실에서 학습자들에게 쓰기를 어떻게 지도할 것인지에 대한 내용과 학습자들이 학문 목적의 쓰기를 어떻게 하고 있는지를 분석한 연구가 많았다. 한편 학문 목적의 한국어 학습자가 성공적으로 과제를 수행하기 위해 갖추어야 할 지식별로 연구 결과를 분석한 결과 학문 목적이라는 특수 상황의 맥락을 반영한 연구가 특히 많았다는 것을 알 수 있었다. 앞으로의 연구는 이와 같은 맥락 지식을 더욱 구체화하는 동시에 학문적 담화공동체가 요구하는 내용, 언어, 쓰기 처리 지식이 무엇인지를 찾고 이를 교육할 수 있는 방안을 제시할 수 있도록 방향을 맞추어야 할 것이다. This study aims to analyze the current trends in researches which were published since the academic community has taken an interest in Korean writing education for academic purpose. Due to a growing number of students that are learning Korean language in order to pursue a bachelor’s or master’s degree, more spotlight has been on developing Korean academic writing education in order to meet their needs. It was necessary that contents and teaching method of such Korean education were tailored to meet the demands of Korean language learners. In particular, many researches were conducted on developing education for Korean writing for academic purposes. Therefore, out of the 230 researches related to Korean language education for academic purpose, 83 that were specifically about Korean academic writing education were analyzed for the purpose of this study. Trend by year showed an increasing total number of researches. When categorized by subject, most of the researches focused on general education plan and revealed a further need for expanding the scope of such research. Furthermore, the study examined the progress of researches that were done on content knowledge, context knowledge, language system knowledge, and writing process knowledge, which are said to be crucial for students to have in order to improve their Korean academic writing skills. Based on the analysis, most of the researches were found to be about forming context knowledge with its focus on genre. This may be the result of noting the fact that most of the students will have to write on specific genre that is required based on their different educational contexts and situations. However, building content knowledge and applying it in academic writing is equally as important as understanding the characteristics of genre. Specifically, there seems to be a need to conduct a research on students’ cross-textual knowledge and development and application of their integrated knowledge. Based on the analysis of existing researches on Korean academic writing education, it was confirmed that there needs to be further studies on designing and developing specific contents and methodology for Korean writing education for academic purpose.

SOI 구조 가속도센서의 온도 특성 해석

손미정(Son Mi Jung),서희돈(Seo Hee Don) 한국센서학회 2000 센서학회지 Vol.9 No.1

One of today`s very critical and sensitive accurate accelerometer which can be used higher temperature than 200℃ and corrosive environment, is particularly demanded for automotive engine. Because silicon is a material of large temperature dependent coefficient, and the piezoresistors are isolated with p-n junctions, and its leakage current increase with temperature, the performance of the silicon accelerometer degrades especially after 150℃. In this paper, The temperature characteristic of a accelerometer using silicon on insulator (SOI) structure is studied theoretically, and compared with experimental results. The temperature coefficients of sensitivity and offset voltage (TCS and TCO) are related to some factors such as thermal residual stress, and are expressed numerically. Thermal stress analysis of the accelerometer has also been carried out with the finite-element method(FEM) simulation program ANSYS. TCS of this accelerometer can be reduced to control the impurity concentration of piezoresistors, and TCO is related to factors such as process variation and thermal residual stress on the piezoresistors. In real packaging, The average thermal residual stress in the center support structure was estimated at around 3.7x10⁴Nm²℃^(-1) at sensing resistor. The simulated γ_(pT) of the center support structure was smaller than one-tenth as compared with that of the surroundimg support structure.

손미정(Mi Jung Son),서희돈(Hee Don Seo) 한국센서학회 2000 센서학회지 Vol.9 No.3

In this paper, we proposed the new bridge combination detection method for three dimensional piezoresistive silicon accelerometer, and the accelerometer with SOI structures was fabricated by bulk micromachining technology for using higher temperature than 200℃. The sensitivities of fabricated accelerometer for X, Y and Z-axis acceleration were about 8mV/T·G, 8mV/V·G and 40mV/V·G. The nonlinearity of the output voltage was 1.6%FS and cross-axis sensitivity was within 4.6%. We confirmed that the three bridges detection method is very simple and the output characteristics of this accelerometer were similar to arithmetic circuit method accelerometer. The temperature characteristics of SOI structure accelerometer showed high operating temperature and good stability. And the temperature coefficient of offset voltage and sensitivity were 1033ppm ℃^(-1) and 1145ppm ℃ respectively.

본 논문에서는 Enhanced Segmentized Clear Channel Assessment(ESCCA)를 수행하여 디바이스의 데이터 전송기회를 증가시킴으로써 전체 네트워크의 전송효율을 향상시킬 수 있는 기법을 제시하였다. 본 논문에서 제시한 기법은 IEEE 802.15.4 에서 채널 상태탐지를 위해 수행되는 Energy detection based CCA 의 기간을 반으로 나누고, 채널 상태에 따라 CCA 를 추가적으로 수행함으로써 디바이스의 패킷 전송기회를 증가시켜 전체 네트워크의 전송효율을 향상시킨다. 제시한 기법의 타당성을 확인하기 위하여 star topology 네트워크에서 디바이스들이 코디네이터로 패킷을 전송하는 환경에 본 논문에서 제시한 기법을 적용하여 IEEE 802.15.4 의 CCA 및 Segmentized CCA 기법을 적용한 결과와 성능을 비교하였다. 실험결과, throughput은 IEEE 802.15.4 CCA에 비해 최대 약 10kbps, 평균 CCA 횟수는 최대 약 15회 감소하였음을 확인하였다. This paper proposed Enhanced Segmentized Clear Channel Assesment(ESCCA) for the IEEE 802.15.4 networks. This method divides original CCA into two groups to check precise channel status and perform additional CCA to increase throughput performance. Through the proposed method, the device can access the channel more often, so the transmission efficiency of the IEEE 802.15.4 network improves. To confirm the feasibility and usability of the proposed method, computer simulation has been performed. In the simulation, a star topology with one coordinator and a lot of devices is considered and the traffic flows are all one way, with the communication directed to the coordinator. Simulation results_ show the proposed method is improving maximum 10 kbps of throughput and decreasing maximum 15 of the average number of total CCA than IEEE 802.15.4 CCA method.
