Recently, the importance and interest about the assistive devices and assistive technology service for rehabilitation is being increased. Many people with disabilities are using suitable assistive devices to assist and get over their disadvantage. But most of the assistive device was standardized and it doesn't fit often to individual situation and condition. Therefore, the assistive devices should be modified to fit the user's condition and life environments. In this paper, we provided an assistive technology service for a child who has some difficulties about communication and learning due to the Cerebral Palsy. A switch was modified for him to help to cognize and express something. The switch was designed to be controlled by his finger which is unique method to move freely. After that, the child could freely communicate with other and the learn and read a book using the device by himself. Therefore, the learning ability was greatly improved and we expect that he will easily adapt to social life. 많은 장애인들이 자신에게 적합한 보조기기를 사용하고 있고 그 수가 증가하고 있지만, 이러한 현재 시중에 나와 있는 보조기기들은 표준화 되어 있기 때문에 개개인의 환경과 상태에 적합하지 않다. 이 문제를 해소하기 위해서는 보조공학 서비스가 필요하다. 본 논문에서는 뇌성마비로 인하여 의사소통 및 학습이 어려운 아동에게 학습에 도움을 주는 보조공학 서비스를 적용하고 평가하였다. 인지능력은 있지만 자신의 의사를 말로 하지 못하고 자신의 신체를 자의적으로 움직일 수 없는 아동에게 제약적이나마 움직임이 가능한 손 부위를 이용하여 컴퓨터를 사용할 수 있도록 스위치를 개조하여 적용해 주었다. 그로 인해 아동은 적용해 준 스위치를 이용하여 학습에 필요한 의사표현을 할 수 있고 책도 읽을 수 있게 되었다.

The subject basin of the research was the basin of Yeongcheon Dam located in the upper reaches of the Kumho River. The parameters of the model were derived from the results of abstracting topological properties out of rainfall-runoff observation data about heavy rains and Digital Elevation Modeling(DEM) materials. This research aimed at suggesting the applicability of the CELLMOD Model. a distribution-type model, in interpreting runoff based on the topological properties of a river basin, by carrying out runoff interpretation for heavy rains using the model. To examine the applicability of the model, the calculated peaking characteristics in the hydrograph was analyzed in comparison with observed values and interpretation results by the Clark Model. According to the result of analysis using the CELLMOD Model proposed in the present research for interpreting the rainfall-runoff process, the model reduced the physical uncertainty in the rainfall-runoff process, and consequently, generated improved results in forecasting river runoff. Therefore it was concluded that the algorithm is appropriate for interpreting rainfall-runoff in river basins. However, to enhance accuracy in interpreting rainfall-runoff. it is necessary to supplement heavy rain patterns in subject basins and to subdivide a basin into minor basins for analysis. In addition, it is necessary to apply the model to basins that have sufficient observation data, and to identify the correlation between model parameters and the basin characteristics(channel characteristics).

朴埈賢,趙兪貞,尹晟燮,許完旭,金亨順 대한금속재료학회 2002 대한금속·재료학회지 Vol.40 No.7

In order to elucidate the fundamental aspects of the minerals formation processes during sintering, the Fe_2O_3-CaO-Al_2O_3-SiO_2 system and the effect of MgO on synthesized iron ore sinter were studied by image analysis and X-ray diffraction method. Most existed calcium ferrite was identified to be a solid solution of CaO·2Fe_2O_3 with a small amount of solubility of Al_2O_3 and SiO_2. With an increase of the content of Al_2O_3 in the system, the amount of calcium ferrite was increased. On the other hand, the amount of calcium ferrite was decreased, and the amount of hematite was increased with increasing the content of SiO_2. Crystal structure of calcium ferrite with Al_2O_3 and SiO_2 was changed from monoclinic to triclinic as well as the unit cell volume shrank with fixing Al_2O_3 and increasing SiO_2. With increasing the content of MgO(1∼3 wt%), the amount of magnetite was increased and hematite was decreased but calcium ferrite was not changed.

말기신부전 환자의 혈색소 순환 : 투석 방식에 따른 양상 비교 및 관련 인자들에 대한 고찰

최재혁,김준섭,원기범,박준형,탁우택,이정호 동국대학교 의학연구소 2009 東國醫學 Vol.15 No.2

혈색소 순환은 말기신부전 환자에서 인체 재조합 적혈구 조혈 인자를 투여하여 빈혈을 치료하는 동안 빈번히 관찰되며 이는 환자의 입원과 사망률과 관계가 있다고 알려져 있다. 이에 저자는 투석중인 말기 신부전 환자를 대상으로 혈색소 순환 양상과 이와 연관된 인자들을 알아보고자 하였다. 혈색소 순환의 관련 인자들을 알아보기 위하여 투석 치료를 받고 있는 환자 40명 (혈액투석 환자군: 20형, 복막투석 환자군: 20명)을 대상으로 투석 시작부터 1년 동안의 환자의 나이와 성별, 투석시작 1년간의 평균 Hb, 수혈 횟수, 총입원 횟수, 감염으로 인한 입원 횟수, 혈청 ferritin 농도, 혈청 transferrin saturation (TSAT), 철분제제 복용 유무, 일주일 동안 투여된 rHuEPO 양, rHuEPO의 변화량, 알부민, C-reactive protein (CRP) 및 입원 원인 등을 후향적으로 조사하였다. 전체 환자 40명 중 33명 (82.5%)에서 혈색소 순환이 관찰되었다. 혈액투석 환자군에 비해 복막투석 환자군에서 혈색소 순환 첫수가 유의하게 높았다 (p=0.037).혈색소 순환 발생군과 혈색소 순환 미발생군의 관련인자들을 비교하였을 경우 혈색소 순환 발생군에서 총 입원 첫수 (p=0.01), 감염으로 인한 입원 횟수 (p=0.036)가 유의하게 많았으며, 혈중 알부민 수치는 유의하게 낮았다 (p=0.003).그러나 두 군간의 나이, 성별, 수혈 횟수, 혈청 ferritin농도, 혈청 transferrin saturation (TSAT) 및 혈청 철분 농도는 유의한 차이가 없었다. 혈색소 순환의 빈도는 일주일 동안 투여된 r-HuEPO변화량과 양의 상관관계를 보였고 (p=0.003),혈중 알부민 수치와 음의 상관관계를 보였다 (p=0.013). 복막투석 환자군에서 혈액투석 환자군에 비해 혈색소 순환이 유의하게 높게 발생하였다. 일주일 동안 투여된 r-HuEPO 변화량, 입원 및 혈청 알부민 수치는 투석 시작부터 1년 동안의 혈색소 순환과 관련이 있었다. Hemoglobin cycling is frequently observed during treatment of anemia with recombinant human erythropoietin (r-HuEPO) in patients with end stage renal disease (ESRD) it is also reported to be associated with hospitalization and morbidity. We analyzed hemoglobin cycling and potential associated factors in patients on dialysis. Forty new dialysis patients (20 hemodialysis, HD and 20 peritoneal dialysis, PD) were recruited during their first year. Age, gender, mean hemoglobin level, frequency of transfusion, frequency of hospital admission, frequency of admission due to infection, serum ferritin, transferrine saturation, iron levels, rHuEPO dose per week, serum albumin, and c-reactive protein were retrospectively evaluated in order to examine the possible correlations with hemoglobin cycling. Thirty-three patients (82.5%) were identified in the hemoglobin cycling group. The PD group had a higher frequency of hemoglobin cycling than did the HD group (p=0.037). The hemoglobin cycling group showed a significantly higher frequency of hospital admission (P=0.001), admission due to infection (p=0.036) and a lower serum albumin level (p=0.003) than the other group, but there was no significant difference between the groups for age, gender, frequency of transfusion, serum ferritin, transferrine saturation, and iron levels. The frequency of hemoglobin cycling showed a positive correlation with the i-HuEPO dose variation per week (p=0.003) and a negative correlation with serum albumin level (p=0.013). The PD group had a higher frequency of hemoglobin cycling than the HD group, and the change of rHuEPO dose per week, hospitalization and serum albumin were associated with the hemoglobin cycling during the first year of dialysis.
