<B>Graphic Abstract</B> <P>The cover shows an image of fully rollable transparent nanogenerators synthesized using chemical vapor deposition grown large-scale graphene sheets as transparent electrodes and piezoelectric ZnO nanorod arrays. Sang-Woo Kim, Jae-Young Choi, and co-workers report on p. 2187 the electrical and structural stability of the nanogenerators, with excellent charge scavenging performance under external mechanical loads such as bending and rolling. This study shows that graphene-based nanogenerators are very promising for self-powered rollable transparent device applications. <img src='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content.gif' alt='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content'> </P>

The ammonia gas sensors were fabricated with the ZnO-based thin films grown by a RF magnetron sputtering method. We investigated the sensitivity and response time according to temperature variation and ammonia gas concentration. The sensors sputtered in oxygen atmosphere showed higher sensitivity than those sputtered in argon atmosphere. The Au(0.3 wt.%) doped-ZnO thin film sensors aged at 330 ℃ showed the maximum sensitivity of 28 and good response time at a working temperature of 250 ℃ and to 160 ppm ammonia gas. The Pt(0.1 wt.%) doped-ZnO thin film sensors showed the maximum sensitivity at a low working temperature of 200 ℃.

We have investigated a performance of bio-electrode reactor for removal of nutrient like a nitrogen, phosphorus and organic substrate. Lab scale of bio-electrode reactor was operated with synthetic and tannery wastewater. Iron bar and stainless steel used for anode and cathode respectively. In experiment with synthetic wastewater, we were able to obtain the optimal current density range of 2.4-40 mA/dm² after 48 hrs operating time. And in that experiment, about 70~73% of ammonia nitrogen and 54~64% of phosphorus were removed. In experiment with tannery wastewater at 2.4-4.0 mA/dm², the removal rate of ammonia nitrogen, phosphorus and organic substract were about 62-69%, 45~59% and beyond 79% respectively.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

The microheaters with Si_(3)N_(4)(1500Å)/SiO_(2)(3000Å)/Si_(3)N_(4)( 1500Å) diaphragm were fabricated by thin film technology and silicon micromachining techniques. Pt and poly-Si(n+) materials were used as heater materials of microheater. Pt temperature sensor was fabricated to detect the temperature of microheaters. The thermal analysis including temperature distribution on diaphragm and power consumption of the microheater were executed by the FEM method and heat transfer equations. The power consumption of the Pt and poly-Si(n+) heaters were measured and compared to that of thermal analysis by FEM simulation.

The DMA(Dimethylamine) gas sensors were fabricated with the ZnO-based thin films grown by a RF magnetron sputtering method. We investigated the sensitivity and response time according to temperature variation and DMA gas concentration. The ZnO-based thin film sensors sputtered in oxygen atmosphere showed higher sensitivity than those sputtered in argon atmosphere. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3) and V_(2)O_(5) and sputtered in oxygen atmosphere showed the maximum sensitivity of 218(working temperature, 250 ℃, DMA gas, 160 ppm) and speedy response time. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3), TiO_(2) and V_(2)O_(5), sputtered in oxygen atmosphere and aged at 330 ℃ showed the maximum sensitivity of 156(working temperature, 250 ℃, DMA gas, 160 ppm).

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.
