GALLIUM NITRIDE NANOWIRES ENHANCED HIGH-EFFICIENCY COLD CATHODE FLUORESCENT LAMP
JEFF. T. H. TSAI,ZI-JIE LIAO 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2011 NANO Vol.6 No.5
We demonstrated a cold cathode fluorescent lamp that contains gallium nitride (GaN) nanowires at the electrode surfaces in a gas discharge light source to enhance the power efficiency of this luminance system. GaN in the nanowire structure has a high geometric aspect ratio, which makes it an ideal plasma ignition enhancer. The nanostructure enhancer not only improves a lower ignition voltage but also eliminates the use of mercury in the conventional cold cathode fluorescent lamp system. Due to high temperature of plasma, the GaN nanowires are partially dissociated to release the Ga ions into the lamp. Because the Ga ion has a large capture cross-section of electrons, it helps the lamp electrodes to maintain a high electric resistance. This could enhance the power efficiency and prevent the sputtering effect on the electrode to improve the lifetime of the lamp. This mercury-free approach also makes such cold cathode fluorescent lamp as an environment-friendly device.

The purpose of this study was to ascertain whether an oral, non-prescription, nutritional supplement compound composed of a proprietary alkali-buffered creatine monohydrate and cetylated fatty acids mixture (Kre-Celazine ) was efficacious in reducing or eliminating refractory pain and inflammation, without untoward effects, in Juvenile Rheumatoid Arthritis ( JRA), which is also called Juvenile Idiopathic Arthritis ( JIA). JRA/JIA is a patho-physiologically complex, chronic childhood autoimmune inflammatory disease of unknown etiology. Numerous studies have unsuccessfully attempted to pinpoint a possible common initiation event. Officially considered an affliction of children below the age of 16 years, an initial diagnosis has been confirmed in infants less than 1 year old, to individuals older then 17 years. In this study, sixteen juveniles, ages 7 through 16 years, experiencing long-standing, unremitting pain and inflammation despite previous use of prescription anti-inflammatory drugs and NSAIDs, were enrolled in a 30-day, open-label clinical study and treated with Kre-Celazine. Efficacy of this nutritional supplement was determined by the juvenile’s personal physician and based on observations of the following: (1) significant reduction or elimination of palpable signs of inflammation; (2) renormalization of range of motion; (3) reduction or absence of perceived pain as reported to the physician by the patient; (4) renormalization of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) values. In addition, the individual’s previous steroid or non-steroidal anti-inflamatory medication(s) were reduced or eliminated in a stepwise progressive fashion during the study.
Contemporary Art and Education: A Critical Alliance
Jeff Adams 한국국제미술교육학회 2013 미술과 교육 Vol.14 No.3
Art, and contemporary art in particular, has played a complex and paradoxical role in education. On the one hand it can offer unique modes of expression that provide learners with the means to explain and understand their identity and their life-worlds; on the other hand, art can confound and disrupt ordinary education practices, not lending itself easily to assessment or curricula routines, and furnishing learners with a critical voice that may be unwelcome within mechanistic educational processes. Using some examples drawn from primary school pupils’ conspicuously contemporary artworks, I argue that the presence and viability of these critical and idiosyncratic art practices in schools may be an indicator of the health of an education system as a whole.
Foreign Direct Investment and Host-Country Trading Blocs
( Jeff Heinrich ),( Denise Eby Konan ) 세종대학교 경제통합연구소 2000 Journal of Economic Integration Vol.15 No.4
We consider the impact of preferential trade agreements (PTAs) on horizontal foreign direct investment (FDI) coming from parent countries outside the PTA. While easier access to a larger market due to a PTA may justify new FDI, preexisting investments may be rationalized as firms concentrate production in a single plant in the PTA. Which effect dominates depends on the extent of pre-PTA tariff jumping. The number of firms in the industry and non-PTA welfare may rise or fall. PTA welfare increases regardless of PTA-induced changes in inward FDI.
