Background: The presence of visuospatial impairment can make patients slow functional recovery and impede the rehabilitation process in TBI patients. Objective: The aim of this study is to investigate effects of prism adaptation treatment for functional outcomes in patients following traumatic brain injury. Methods: The subject received prism adaptation treatment for 2 weeks additionally during traditional rehabilitation for 4 weeks. The Patient has prism adaptation treatment while wearing wedge prisms that shift the external environment about $12^{\circ}$ leftward. The patient received 10 sessions, 15-20min each session. Outcome measures were visuospatial deficit(line bisection, latter cancellation), Visual and spatial perception(LOTCA-visual perception and spatial perception), motor function of upper extremity(FMA U/E; Fugl-Meyer motor assessment upper extremity, ARAT; Action research arm test), balance(BBS; Berg Balance Scale), mobility(FAC; Functional ambulation classification) and functional level(FIM; Functional independent measure). All Assessments took place on study entry and post-treatment assessments were performed at discharge from the hospital. Results: After prism adaptation, the visuospatial impairment scores improved as indicated in the line bisection(-15.2 to -6.02), latter cancellation(2 to 0) and LOTCA- spatial perception scores(7 to 9). The upper motor function improved as indicated in the scores of affected FMA U/E(21 to 40) and ARAT(4 to 22). Ambulation and balance improved as indicated in the BBS scores(25 to 38) and FAC scores(0 to 4). ADL function improved as indicated in the FIM total scores 54 to 70(motor 34 to 61, cognition 20 to 29). Conclusion: Prism adaptation did improve functional level such as motor functions and ADL abilities in TBI patient. Further research is recommended.

We have analyzed the cause of black "mura" and measured it in prism light-guide plate (LGP). Properties of components used in a back light. unit (BLU) have changed by Simulation Tool. We get major factor of black "mura" for improvement in prism LGP. For the improvement of black "mura", removal of brightness "mura" at input light part must precede preferentially because of reflection characteristics of the prism LGP. Removal of brightness "mura" is improved by changing of input light part in LGP and dispersion treatment.

In this study, it was investigated about the variation of luminance properties in LED backlight with geometrical shape such as prism or lens shape on the light-entering face. Generally, LED light source has the loss in backlight system because it has horizontal direction light. PMMA(Poly-Methyl-Meta-Acrylate) is used LGP(Light-Guide-Plate) in conventional backlight system. PMMA has low refraction angle. so that. horizontal direction light was not used in backlight system. The addition of geometrical shape in light-entering face in LGP improves the luminance characteristics because it prevents horizontal direction light generation in light-entering-face. Prism or lens shape in same pitch disposition was almost same without these treatment such as the value of 1% rising. Besides. It is particular that the gap of these shape such as the value of 0.407~0.22mm prevents horizontal direction light, so then it contributes luminance rising at 5.6%.

목 적 : 혈역동 상태가 불안정한 신부전 환자에서 CRRT 시행이 증가하고 있으나 국내에서는 소아 환자에서의 보고는 드물다. 그러므로 저자들은 소아 환자들에서 CRRT의 치료 경험을 보고하고자 한다. 방 법 : 2001년 5월부터 2004년 5월까지 서울아산병원에서 CRRT를 시행한 소아 환아 23례를 대상으로 하여 원인 질환 및 신대체요법 시작 시 임상 양상과 경과, CRRT의 방법과 결과를 검토하였고 생존군과 사망군 사이의 차이를 비교 분석하였다. 결 과 : 23명의 환아 중 남아가 12명, 여아가 11명이었고 연령은 3일에서 16세(중간값 5세)였다. 체중은 2.4 kg에서 63.9 kg(중간값 23.0 kg)였고 20 kg 이하가 5명이었다. 대상 환아의 기저 질환은 종양성 질환이 9명, 다장기 부전 증후군 5명, 선천성 대사이상 질환에 의한 고암모니아 혈증 4명, 간기능 부전과 동반된 급성 신부전 3명, 확장성 심근증 1명, 선천성 신증후군 1명 이었다. PRISM III 점수는 $17.6{\pm}7.6$이었고 평균 부전 장기의 수는 $3.0{\pm}1.7$개였다. CRRT를 시행한 기간은 1일에서 27일(평균 9일)이었다. 23명의 환아 중 11명(47.8%)이 생존하였다. 이중 4명에서 후유증이 남았는데 1명은 뇌출혈이 발견되었고 2명은 만성 신부전으로 진행하였으며 또 다른 1명에서는 내경정맥에 2중 도관 삽입과 관련된 상대정맥 혈전으로 인해 유미흉이 발생하였다. 생존군과 사망군을 비교하였을 때 생존군에서 CRRT 시작 당시의 PRISM III 점수와 투여되는 승압제의 수가 유의하게 낮았다(P<0.05). 결 론 : 혈역동상태가 불안정하고 다장기 부전이 동반된 급성 신부전 환아에서 CRRT를 효과적으로 시행할 수 있었고 생존율에는 CRRT 시작 전 PRISM III 점수, 승압제 투여 정도가 중요한 요인이었다.

Thin films of the SiO2-TiO2-PDMS composite material have been prepared by the sol-gel dip coating method. Acid catalyzed solutions of tetraethoxy silane (TEOS) and polydimethyl siloxane (PDMS) mixed with titanium isopropoxide Ti(OiPr) were used as precursors. The optical and structural properties of the organically modified 70SiO2-30TiO2 composite films have been investigated with Fourier Transform Infrared Spectroscopy (FT-IR), UV-Visible Spectroscopy (UV-Vis), Differential Thermal Analysis (DTA) and prism coupling technique. The films coated on the soda-lime-silicate glass exhibit 450-750 nm thickness, 1.56-1.68 refractive index and 88-94% transmittance depending on the experimental parameters such as amount of PDMS, thermal treatment and heating rate. The optical loss of prepared composite film was measured to be about 0.34 dB/cm.

Tamoxifen is an antagonist of the estrogen receptor and currently used for the treatment of breast cancer. The current treatment of cutaneous leishmaniasis with pentavalent antimony compounds is not satisfactory. Therefore, in this study, due to its antileishmanial activity, effects of tamoxifen on the growth of promastigotes and amastigotes of Leishmania major Iranian strain were evaluated in vitro. Promastigotes and amastigotes were treated with different concentrations (1, 5, 10, 20, and $50{\mu}g/ml$) and time periods (24, 48, and 72 hr) of tamoxifen. After tamoxifen treatment, MTT assay (3-[4,5-dimethylthiazol-2-yl]-2,5 biphenyl tetrazolium bromide assay) was used to determine the percentage of live parasites and Graph Pad Prism software to calculate $IC_{50}$. Flow cytometry was applied to investigate the induction of tamoxifen-induced apoptosis in promastigotes. The half maximal inhibitory concentration ($IC_{50}$) of tamoxifen on promastigotes was $2.6{\mu}g/ml$ after 24 hr treatment. Flow cytometry analysis showed that tamoxifen induced early and late apoptosis in Leishmania promastigotes. While after 48 hr in control group the apoptosis was 2.0%, the $50{\mu}g/L$ concentration of tamoxifen increased it to 59.7%. Based on the in vitro antileishmanial effect, tamoxifen might be used for leishmaniasis treatment; however, further researches on in vivo effects of tamoxifen in animal models are needed.
