The lead has to be removed for the recycling of copper alloy. The lead cannot be removed from the copper alloy by oxidation. It can be removed by the evaporation because of its high vapor pressure. However, rate information is found on removal of lead from copper alloy. The purpose of present work is to provide a fundamental knowledgs on the removal of lead from the copper alloy by evaporation. Gas injection was made in molten copper alloy, and the evaporation rate of lead was measured. The influence of Ar gas flow rate(2~4 L/min), initial contents of lead(2~4wt%Pb), temperature(1200~1400℃) was investigated based on the thermodynamic and the kinetics. The rate constant is increased with increasing flow rate of Ar and temperature. Though amount of lead removed is increased with higher initial lead concentration, the rate constant is not changed significantly. The activation energy is estimated from the temperature dependence of the rate constant. Also removal of lead from the copper by adding chloride was made for the comparison

The purpose of this study was to test the effects of speed reading development program which was constructed as the clinical treatments of the five psycho-phypical variables of eye movements and perceptual processes. The clinical treatments of this program were integrated with a reading activity to form a wholeness of behaviors and to synthesize the interaction effects among treatments. The output behaviors could be developed and explained, not in terms of fixation, comprehension, and saccading, but in terms of power, flexbility, speed, rhythm, focussing, concentation, and comprehension. Along with the four weeks' manipulation of an experimental time series design, both speed and comprehension variables of college students' reading behaviors were significantly developed at the level of reading their textbooks at the rate of about two thousand and six hundred words per minute which were easily contacted.

신수혈의 침자극과 황기약침이 실험용 생쥐의 면역활성물질인 IL-1 α의 遺傳子發現에 미치는 影響

申相習,朴元煥,洪文燁,李泰均,崔達永 대한동의병리학회 1999 동의생리병리학회지 Vol.13 No.2

체내의 환경을 항상적으로 유지하는 생체방어체계에는 면역활성물질이 있으며, 이러한 면역활성물질의 적절한 발현이 생체의 항상성을 유지하는데 작용하게 된다. 이에 한의학에서는 생체의 항상성 유지와 체내의 면역력 증가를 위해 많은 요법들이 시행되어 왔는데, 그 중 자침요법과 약침요법이 많이 응용되고 있다. 그러나 침자극과 약침의 효과에 대한 기전은 기대하는 만큼 제시되지 못하고 있다. 이에 본 논문은 침자극과 약침의 효과에 대한 기전을 밝히는 방법의 일환으로서 면역활성물질인 IL-1α가 補腎臟, 振氣化, 祛水濕, 强腰脊, 益水壯火 등의 穴性이 있는 신수혈(BL23)의 침자극과 황기약침처치를 통해 어떻게 발현하는가를 관찰하였다. 그 결과, 면역 증강 작용을 나타내는 cytokine IL-1α 에 대한 침자극의 반응은 관찰되었고, 황기약침에 의한 IL-1α 의 발현은 명확하지 않았다. 그러므로 신수혈을 이용한 cytokine IL-1α의 추적은 황기약침의 효과보다 침자극의 효과에 대한 근거를 추측할 수 있을 것이며, 뿐만 아니라 침자극에 의한 면역반응정도를 통해 질병의 진행상태를 나타내는 진단지표로서 활용가능성이 있을 것이다. Acupuncture and Radix Astragali aqua-acupuncture stimuli have long been used to cure human diseases. However, it still remains to be unknown on its action mechanism, physiological and biochemical aspects. Thus, many attempts were made to show the scientific background covering the above mentioned mechanisms. Most recent studies show that these tests improve blood circulatory system and increase leucocyte counts. In this study, we have applied the acupuncture stimuli to mouse Sinsu(BL23), which is a stimulative point of oriental medicine, to see if cytokine such as IL-1α can be detected. Mice were treated with lipopolysaccharide(LPS) for inflammation induction, and then reverse transcriptase-polymerase chain reaction (RT-PCR) using each primer set was performed to trace the amounts of mRNA. The results are as follows ; 1. The RT-PCR product using IL-1α primers was detected as 450 bp on agarose gels and the IL-1α gene was not expressed in normal mice at 15 min after the removal of acupuncture. However, it was gradually increased indicating a faint expression after 30 min. 2. IL-1α was expressed in LPS-treated mice 30 min after the acupuncture was pulled out, and expressed most highly at 3 h after the removal of acupuncture. The gene expression of LPS-treated mice were more effective than those of normal mice. 3. IL-1α was not expressed in normal mice and LPS-treated mice from 30 min to 3hs. after Radix Astragali aqua-acupuncture stimulation. Therefore, a tracing the gene expression of cytokine IL-1α can be used more not only for a basis of the effect of acupuncture stimulation but a diagnosis guide through the immunological action than the effect of Radix Astragali aqua-acupuncture. Moreover, we need to further study the cytokine's expression in Radix Astragali aqua-acupuncture stimulation.

최성욱,이상엽,김현웅,윤일한 仁濟大學校 白病院 2010 仁濟醫學 Vol.31 No.-

Objectives: To assess macular function after vitrectomy and membrane removal in eyes with idiopathic epiretinal membrane by means of multifocal electroretinogram (mfERG). Methods: Visual acuity, macular thickness measured by optical coherence tomography (OCT), and mfERG recordings were achieved for 14 eyes of 14 patients with idiopathic epiretinal membrane. All exams were performed before epiretinal membrane surgery and 1, 3, and 6 months after surgery. The average retinal response density and implicit time of each local response were estimated as anatomic macular areas corresponding roughly to 5 rings. Preoperative and postoperative responses of visual acuity, macular thickness, and mfERG were compared. The correlations of the change of retinal response density, visual acuity, and macular thickness were analyzed. Results: There were no significant changes in amplitude and implicit time measured by mfERG before and after the surgery (p>O.05). There were no significant correlations between the changes of amplitude and implicit time and visual acuity and macular thickness. Conclusion: Changes in mfERG recordings were not useful for predicting clinical prognosis after epiretinal membrane surgery.

TiO₂ 졸-겔 코팅 막에 의한 Humic Acid의 광분해 : 화학적 산화법에 의한 부식산의 분해처리 기술에 관한 연구(Ⅱ);Characterization of Humic Acid in the Chemical Oxidation Treatment (Ⅱ)

석상일,안복엽,서태수,이동석 江原大學校 附設 環境硏究所 2000 環境硏究 Vol.17 No.-

The degradation of humic acid using TiO₂ coatings studied. TiO₂ coatings were prepared by dip-coating method. Sol solutions for coating were prepared by mixing the gel, which can be produced by the reaction of TiOCl₂ and NH₁OH solution, and hydrogen peroxide solution, and hydrolysis of titanium tetraisopropoxide (TTIP). It was shown from SRD that coatings from sol aged at 100℃ for 18h with titanium peroxo solution were crystallized to anatase in the range of temperatures of 25℃ to 500℃. In contrast, those coated from TTIP were crystallized to anatase at temperature above 400℃. So the sols originated from TiCl₄ can be applied for not only on the heat-resistance substrates but on the plastic substrates. Thickness and the quality of the films were dependent on the withdrawing speed, the concentration of sol, and the number of coating. The films showed various interference colors depending on the thickness of them. In the case that the films coated 2 times at withdrawing speed of 2.5cm per minute by 0.2M sol, the films had a transparent light blue color with thickness of around 50nm. It was known from the result of photo-degradation by TiO₂ coatings using humic acid that the removal efficiency of COD_(cr) was over 85% after illumination of UV/H₂O₂ for 40min, and that of UV/VIS absorbable materials was over 95%. TiO₂코팅매체를 이용한 humid acid의 광분해 특성을 조사하였다. TiO₂코팅은 TiOCl₂ 수용액을 암모니아수로 침전시킨 겔을 과산화수소로 용해한 용액 혹은 졸이나 titanium tetraisopropoxide (TTIP)의 가수분해로부터 제조한 졸을 이용하여 dip-coating법으로 제조하였다. Titanium peroxo 용액을 열처리하여 제조한 졸을 이용한 코팅층은 X-선 회절 분석으로부터 25℃~500℃ 온도 범위에서 모두 anatase형 결정구조를 가지고 있었다. 반면에 TTIP의 가수분해로 생성된 졸로부터 만든 코팅막은 400℃ 이상에서 anatase의 결정형이 나타났다. 이로부터 titanium peroxo 용액을 열처리하여 제조한 졸은 내열성 및 비내열성 기판에도 결정성 TiO₂ 코팅층을 만들 수 있는 장점이 있다. 코팅막의 두께 및 균일성은 인출속도, 코팅졸의 농도 및 코팅 횟수에 영향을 받았으며, 코팅막의 두께에 따라 다양한 간접색상을 나타냈다. 0.2M 졸을 이용하여 인출속도 2.2cm/min로 2회 코팅했을 경우, 약 50nm 두께의 투명하면서도 균일한 흐린 남색을 띠는 TiO₂코팅막을 얻을 수 있었다. 이상의 방법으로 직경 0.3cm의 유리구슬에 TiO₂ 코팅막을 제조한 후 580cm³의 반응조를 사용하여 UV/H₂O₂ 공정으로 humic acid를 40분 동안 광반응시킨 결과, 초기 시료의 COD_(cr)(40ppm)을 약 85% 이상, 흡광물질을 약 95% 이상 제거하였다.
