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.

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.

Objectives: This study was performed to figure out the effects of herbal mesotherapy on abdominal fat in obese women. Methods: Forty obese women those who were diagnosed abdominal obesity had been recruited during February, 2008. They were randomly assigned experimental or control group under block-randomization. Experimental group were treated with Sobi-eum(Xiaofei-yin) injection during 6 weeks (2 times a week) and placebo group were treated with normal saline injection under same procedures. Anthropometry, body impedance analysis, fat computed tomography, blood test, and questionnaires had been administered before and after the treatment. Results: Four subjects were dropped out (voluntary give up), so 18 in experimental group and 18 in placebo group were evaluated. There were significant changes after treatments in both groups. Although no significant differences have been found in the result of anthropometry, body impedance analysis and fat computed tomography between two groups, in the experimental group, the changes of total fat area had a highly significant relationship with all part of abdominal fat. While the placebo group had highly significant relationships with subcutaneous fat area, superficial and deep subcutaneous fat area but not with visceral fat area. Conclusions: Compaired with saline group, herbal mesotheraphy Sobi-eum(Xiaofei-yin) is effective in reduction of visceral fat after adjusting TFA.

The purpose of this study is to draw the characteristics of transparency in overlapping by focusing on the relationship between overlapping, which is the principle of building composition, and transparency, which is a representative concept of modern architecture. Transparency in modern architecture goes beyond literal Transparency and appears in overlapping can be expressed as the concurrency of space in the implication of space and ambiguity, and the scalability in the inter-intrusion of inside and outside. As a result, overlapping will be a principle of architectural composition that can meet the pluralistic tendency required in modern society.

글쓰기의 새로운 인지모형 제안

이아라(Lee Ah-Ra) 국어국문학회 2008 국어국문학 Vol.- No.148

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.
