이아라,장경배,Lee, Ah-Ra,Jang, Kyung-Bae 대한임베디드공학회 2011 대한임베디드공학회논문지 Vol.6 No.4
This study suggests a Healthcare System for elderly and disabled who have mobility impairment and use a wheelchair for long time. Seating long time in a wheelchair without reducing pressure causes high risk of developing pressure sores. Pressure sores come with great deal of pain and often lead to develop complication. Not only it takes time and effort to treat pressure sores but also increases medical expenses. Therefore, we will develop a device to help to prevent pressure sores by measuring pressure distribution while seating in a wheelchair and wirelessly send information to user device to check pressure distribution in real time. The equipment to measure body pressure is composed of FSR sitting mat which is a sensor measuring part and an user terminal which is a monitoring part. The designed mat is matrix formed FSR sensor to measure pressure. The sensor send measured data to the controller which is connected to the end of the mat, and then the collected data are sent to an user terminal through a bluetooth. Developing a pressure monitoring system will help to prevent those who have mobility impairment to manage pressure sores and furthermore relieve their burden of medical expenses.

Fe-loaded zeolite를 이용한 칼럼 실험에서의 Cd & Cr(VI) 동시제거 반응성 평가
이아라,이승학,박준범,Lee Ah-Ra,Lee Seung-Hak,Park Jun-Boum 한국지하수토양환경학회 2006 지하수토양환경 Vol.11 No.1
Cd과 Cr(VI)으로 동시에 오염된 지하수 정화에 반응벽체 공법을 적용하기 위하여 환원능과 흡착능을 동시에 가지는 새로운 반응 물질인 Fe-loaded zeolite의 반응성을 실내 주상실험을 통해 평가하였다. Cd과 Cr(VI)을 동시에 포함한 오염용액을 반응물질이 충진된 칼럼에 주입하고, 이 칼럼을 통과한 유출수에서의 Cd과 Cr(VI) 농도를 측정하여 파과곡선을 얻는 방법으로 본 주상실험을 수행하였다. 유출수의 농도 분석 결과 Cd의 파과는 Cr(VI)의 파과곡선이 완료되는 시점까지 전혀 관찰되지 않아, 반응물질의 전반적인 효율은 Cr(VI)에 대한 반응성에 의해 결정됨을 알 수 있었다. Cr(VI)의 파과곡선은 파과 시작점이 다소 지체되고 파과의 진행 속도도 느려지며 파괴곡선의 상대농도 값이 1까지 증가하는 양상을 나타내었다. 이러한 Cr(VI) 파과곡선의 양상을 정량적으로 묘사하기 위하여 형상계수라고 하는 새로운 계수 ${\alpha}$와 ${\beta}$를 정의하고, 이를 오염물질의 이동방정식에 적용함으로써 파과곡선의 지체 정도와 기울기 정도를 나타내었다. 초기 주입 용액의 농도가 증가할수록 ${\alpha}$값은 감소하였고, 이로부터 파과곡선의 시작 시점이 빨라 지는 것을 알 수 있었다. 또한 초기 주입 용액의 속도가 증가할수록 ${\beta}$ 값이 감소하였으며, 이로부터 파과곡선의 기울기가 점차 가팔라지는 것을 알 수 있었다. 이를 통해 Fe-loaded zeolite를 반응벽체 내 반응물질로 적용할 경우, Fe-loaded zeolite는 지하수 상에 존재하는 서로 다른 이온 형태의 중금속인 Cd과 Cr(VI)을 효과적으로 동시에 제거할 수 있음을 획인하였으며 이때, Fe-loaded zeolite를 통한 Cr(VI)의 파과는 지하수 흐름이 빠를수록 파과의 진행이 더욱 급격히 나타날 것이며 오염농도가 높은 지하수일수록 파과의 시점이 빠르게 나타나 반응물질은 그 사용 한계 에 다다르게 될 것임을 예측할 수 있었다. Laboratory column experiment for simultaneous removal of Cd and Cr(VI) were conducted using newly developed material of Fe-loaded zeolite having both reduction ability and sorption capacity. The solution containing Cd and Cr(VI) was injected into the column and the breakthrough curves (BTCs) for the contaminants were observed at the effluent port. Cd breakthrough was not initialized until Cr(VI) breakthrough was completed. Therefore it could be concluded that overall efficiency of Fe-loaded zeolite should be determined by the reactivity for Cr(VI). The relative concentration of Cr(VI) BTC increased to the unit value while initial breakthrough was delayed and the propagation of breakthrough was slowed. In order to quantitatively describe the shape of Cr(VI) BTC, new parameters of ${\alpha}\;and\;{\beta}$ designated to be shape parameters, were defined and applied in contaminant transport concentration. These parameters were employed to represent the degree of initial breakthrough delay and the degree of breakthrough propagation, respectively. As initial contaminant concentration increased, ${\alpha}$ decreased, which indicated the delay of BTC's initiation. And as initial contaminant flow rate increased, ${\beta}$ decreased, which represented the faster propagation of the BTC. From these results, Fe-loaded zeolite was found to be an effective reactive material for PRBs against heavy metals having different ionic forms in groundwater. And it could be expected that as groundwater flows faster, the propagation of breakthrough would be faster and as contaminant concentration is higher, the initial point of breakthrough would appear earlier.

글쓰기 과정의 "숨은 독자(Hidden Reader)" -글쓰기 과정에서 독자의 작용에 관한 새로운 이해-
이아라 ( Ah Ra Lee ) 국어교육학회 2008 國語敎育學硏究 Vol.31 No.-
이 논문은 글을 쓰는 필자의 의식 안에서 작용하는 독자에 관한 새로운 접근을 담고 있다. 본 연구는, 필자의 의식에 작용함으로써 글쓰기 과정에 참여하는 필자의 대화자가, 필자 자신도 예상독자도 아닌, 필자와 예상독자를 매개하는 제3의 존재라는 발견에서 출발하며, 이 제3의 존재를 가리켜 숨은 독자(Hidden Reader)라 명명한다. 숨은 독자는 예상독자(군)의 시각을 대표할 뿐 아니라 필자의 내면까지를 다 들여다보는 ``내 안의 타자``이자 비평적 독자로서 글 안팎의 수사적 상황을 아우르며 전방위적인 반응(feedback)을 필자의 글에 가함으로써 필자와 상호작용을 주고 받는다. 숨은 독자는 고독한 글쓰기 과정의 동반자이자 필자의 독주를 막는 견제 자이며 필자의 비판적 지지자이다. 숨은 독자는 글의 시작부터 끝까지 필자를 따라가 주며 예상독자에 견주어 필자에게 질문하고 의견을 보낸다. 숨은 독자가 때로는 필자를 옹호하고 때로는 필자에 문제를 제기하며 특정 정보와 지식을 환기시킴으로써, 글에서 선택과 배제가 이루어질 수 있다. 숨은 독자는 이러한 방식으로 글을 제어, 통제해 나간다. 글쓰기란 필자와 숨은 독자의 대화와 조정의 과정이며, 필자는 숨은 독자와의 대화를 통하여 자기 글에 대한 상위인지에 도달할 수 있게 된다. 글쓰기 교육의 목표는 학생 스스로 합리적인 숨은 독자를 생성해낼 수 있는 능력을 길러주는 것이다. This article suggests a new approach to the reader(audience) functioning in the writer`s consciousness. We start by discovering that the reader functioning in the writer`s consciousness is not the writer itself, not the audience, but the third person(being). We suggest to call the third person(being) as ``Hidden Reader``, who is the conversationalist of the writer in the lonely process of writing. The Hidden Reader not only represents the perspective of the anticipated reader(s)/audience(s), but has the ability to look at the writer`s inside view. Therefore it would be good to be called ``The Other inside of a self``. The Hidden Reader is a critical reader that provides omnidirectional feedbacks to the writer with concerning all kinds of rhetorical situation and the ins and outs of text. During the whole time that the writer is writing, the Hidden Reader provides and sends feedback. The questions or feedback of the Hidden Reader are not limited to special circumstances, but to all situations related to the writing, it involves the outer and inner circumstance or situation. The role of the Hidden Reader is to view the writer`s article as an anticipated reader, but if the role of the Hidden Reader is limited to that, there would be no big difference to being called the anticipated reader. However, the hidden reader criticizes/judges the writing from the anticipated reader`s point-of-view, and also has insight to what the writer has not directly expressed. The Hidden Reader throws unlimited questions pertaining to all kinds of rhetorical problem. There is going to be selection and exclusion in writing as the Hidden Reader often defends and supports the writer, or raises questions and brings forward problems to the writer, and invokes(refreshes) specific informations and knowledges. This is the way the Hidden Reader manages and controls the writing. Through dialogue(or interaction) between the writer and Hidden Reader, the writer can arrive at a meta-cognition. The goal of education in writing is for the student to acquire the capabilities of creating a competent Hidden Reader.

This paper introduces a novel theory of organic formation of writing proposing a newly coined term chaosmosing. We suggest a new cognitive model of writing reflecting the chain of chaosmosing in writing process. Our chaosmosing theory of writing rests on the following 3 key points that this paper developed: 1. The process of writing begins with chaos and makes a steady progress toward cosmos. The interim process between chaos and cosmos can be described as chaosmosing which is a consistent operation of chaosmos being formed into a cosmostuniverse) through transformation and generation. 2. Our cognitve model of writing process proposes a new element 'Goal Image' in order to capture the moment of the chaosmosing process. 'Goal Image' is not a goal but the image of a written product that will be completed. It has a property of being pliant (or plastic - 'soft' is not an appropriate term as is not stereoscopic enough) far from being hard. Texts are produced by writers' Goal Images. Produced texts give feedbacks to the Goal Image. These processes are continuously repeated. Writing is a process of organic formation with interaction such as communication and inter-tuning between Goal Image and text. 3. Therefore. writing is both a cognition and a practice of a writer. A writer's cognition changes and evolves through writing and writing itself is a practice of the cognition which has changed and evolved. In other words, writing is a process of constructing and producing knowledge through a confronting of a self and the world. The establishment of 'Goal Image'. which has a property of being pliant rather being fixed and solid. explains the flexibility of a cognitive process and the dynamic nature of writing. the product of the very cognitive process overcoming the fixedness of the previous models and filling the empty space. Specifically. it can answer the questions such as What is the criterion of monitoring? How does writing get changed through monitoring? that were unsolved even with the Flower & Hayes model and later models. It can also deal with the question What kinds of elements mediate the individual steps of a writing and a cognitive process? We show how writing affects a thought and a cognitive process by introducing a new concept chaosmosing. In summary. we believe that our 'organic writing model' is an advance model which models the dynamicity and the flexibility of the evolving process of inter-tuning of cognitive process and writing.
