AbstractWe have developed transmissive low outgassing organic insulator (TLOI) which is suitable for various OLED displays. Until now, there hasn't been insulator that has good process compatibility and contribute to fabricate the long life time, low power consumption OLED panel. Our conventional material has much residue on ITO and make work function of ITO change because of residue, then it couldn't offer the OLED panel which has good reliability. Now we developed new material (TLOI) that satisfies all above‐mentioned characteristics, we report about our recent study.

Published: October 2012

AbstractA new RGB patterning method for realizing high resolution Organic Light Emitting Device (OLED) full color displays is proposed. In this method, a plastic film is used as a shadow mask. The film is patterned by laser ablation in situ on the bottom electrode of the device, (e.g. anode), and the organic layers are then deposited on this electrode. Because the film is patterned after being put on the electrode, issues pertaining to the deformation of shadow masks and/or difficulties with aligning them precisely, are eliminated. This present study has been performed as a feasibility study for this approach. In order to assess the capability of the plastic film as a shadow mask and to test if the mounting and removal of the film on the pre‐deposited organic layer may damage to the organic layers, 20um wide OLEDs were fabricated using a pre‐patterned plastic film. Experimental results show that OLEDs can be patterned by using the plastic film mask with reasonable dimensional uniformity and without causing any significant damage to the pre‐deposited organic layer. Additionally, elemental analysis of the anode surface using Energy Dispersive X‐ray Spectroscopy (EDS) shows that anode surfaces that have been subjected to the laser ablation process are free organic contaminants or oxides, indicating that the patterning process is successful in completely removing the plastic film from the electrode surface without leaving any significant organic contaminants on the metal, and/or in causing oxidation of the metal surface in the patterned areas. These preliminary results therefore suggest that this new method is indeed promising for realizing high resolution displays, specifically 300ppi for small sized displays.

Authors: Chang Yan‐Shuo , Hsu Wei‐Feng , Lin Hoang‐Yan 
Published: October 2012

AbstractThe laser projection display system is attracted interests, especially for the pico‐projector, because of its four advantages: high brightness, color gamut, contrast and low power consumption. Laser projectors have three typical types that are full‐frame, line‐scanned and raster‐scanned systems. The full‐frame laser projection display system will be considered in this paper. To study the speckle contrast of the laser projection system, we have measured different areas and positions and discussed the system with or without polarizer and filmstrip. The speckle contrast was almost the same by measuring different areas and positions. The speckle contrasts with/without polarizer and filmstrip are 0.889/0.683 and 0.57/0.683 when displaying one computer generated hologram.

Wide gamut LCD using locally dimmable four‐primary‐color LED backlight
Authors: Sano Yuma , Nonaka Ryosuke , Baba Masahiro 
Published: October 2012

AbstractThis paper proposes a wide gamut LCD using locally dimmable four‐primary‐color (4PC) LED backlight. Although the color gamut of LCDs has been improved in recent years, it is insufficient to reproduce all the colors in the real world. The objective of this paper is to propose a wide gamut LCD that reproduces all the colors in the real world while keeping the cost increases to a minimum. We evaluated the color gamut reproduced by LEDs of multiple primary colors and selected cyan as the optimal color to be added to the three primary colors to reproduce all the colors in the real world. Therefore, we designed an LED backlight consisting of an additional only‐cyan LED with three‐primary‐color LEDs and developed a prototype LCD with 4PC LED backlight. Furthermore, we developed a local dimming algorithm for the 4PC LED backlight. As a result, we confirmed that the prototype LCD with the 4PC LED backlight is able to cover almost all the colors in the real world and also able to display natural images with highly saturated colors by local dimming.
Effect of intensified discharge in the vicinity of ribs on PDP performance
Authors: Nagano Shinichiro 
Published: October 2012

AbstractIt was determined that the discharge in the vicinity of ribs should be intensified to obtain low‐voltage, high‐luminous efficacy, and high module efficiency. One possible way is to increase the space between ribs and the discharge surface. Even if the amount of space increases by only 2 or 3 µm, it still results in low discharge voltage, large discharge current, and high luminous efficacy. For that reason it might be important to control the micron‐sized particles included in the MgO crystal dispersed layers. Another preferable way is to use ribs with a low electric permittivity (ε) that are represented by porous ribs. Moreover, low‐ε ribs diffuses the high‐energy spots in plasma, resulting in a high luminous efficacy. They feature a significantly lower sustain voltage and a smaller parasitic capacitance as well to facilitate a help high module efficiency. Also, highly porous ribs are expected to increase their practical use in aspects of mechanical strength and impurity gas exhaustion.

Published: October 2012

AbstractPolymethacrylate with semiconducting side chains (P1), synthesized by free radical polymerization, was used as a donor material for polymer solar cells. P1 is of high molecular weight (Mn = 82 kg mol−1), good thermal stability, narrow band gap (1.87 eV), and low‐lying HOMO energy level (−5.24 eV). P1 possesses not only the good film‐forming ability of polymers but also the high purity of small organic molecules. Power conversion efficiencies (PCEs) of 0.63% and 1.22% have been obtained for solar cells with M1:PC71BM and P1:PC71BM as the active layers, respectively. With PC61BM as the acceptor, PCEs of M1 and P1 based devices decrease to 0.61% and 0.76%, respectively. To the best of our knowledge, this is the first report that free radical polymerization can be used to prepare polymer donors for photovoltaic applications.
BASIC LAND SECURITY AND LIVELIHOOD: A STUDY OF COMPENSATION AND SOCIAL SECURITY POLICY FOR LAND‐EXPROPRIATED PEASANTS IN CHINA
Authors: Yang Yi‐fan 
Published: October 2012

SUMMARYFrequently, the discourses on land management and social security policy are kept separate from each other. Access to vital land uses or tenure security, however, are not only relevant to land policy and urban planning but are also important elements of social security policy. Land use planners and policymakers have a huge impact on spaces of poverty and the well‐being of the poor. How can we better understand the relationship between land policy and social security policy? In recent years, global discourses on sustainable development, the Millennium Development Goals or universal human rights increasingly have considered the relationship between land rights and poverty alleviation. The paper will discuss how China framed social security policy with respect to housing, tenure security, urban and rural ownership, improvement of slums, the land rights of women and access to common land. Does the country directly or indirectly link land security to social security policy? In conclusion, the paper will discuss how land security could be contained into the minimum social assistance policy and what the approaching path is in China.

FIGHTING POVERTY AND PROTECTING THE URBAN ENVIRONMENT: THE REFUSE COLLECTORS OF RIO DE JANEIRO, BRAZIL
Authors: Pinto Rogerio F. , Carmo Maria Scarlet Do 
Published: October 2012

SUMMARYThis paper reviews and documents a unique approach to poverty reduction targeting a segment of urban poor in the city of Rio de Janeiro, Brazil: the collectors of recyclable materials discarded by urban residences and businesses, along with their refuse. The approach is unique for Brazil because it combines assorted policy objectives at different governmental levels, two socially/security valued, two environmentally valued and one economically valued. The paper specifically seeks to (a) determine the current profile of collectors, both social and economic; (b) assess the current state of play of the dwindling collectors cooperatives programme, including perceptions of its performance by different stakeholders; (c) describe the current practices and players in the collection of recyclables, with its associated implications; (d) reconstruct the role of key players with a focus on the operational policies and administration of the programme by municipal departments; (e) assess the current priority among social and environmental objectives of the waste collection programme of the municipal government; (f) draw conclusions and recommendations on policies and administration for such programmes, to improve the social outcome for the collectors while still achieving the associated environmental objectives; and (g) draw some comparisons with other Latin American countries that have engaged in similar programmes.

POVERTY, VULNERABILITY AND CLASS: THE EXPANDING NON‐POLAR GROUPS AND DEVELOPMENT
Authors: Sumner Andy 
Published: October 2012

SUMMARYMiddle‐Income Countries (MICs) are now home to most of the world's extreme poor—up to a billion people. At the same time, many MICs are also home to a drastically expanding group of people with expenditures of between $2 and $10 per capita/day. Globally, this ‘emerging middle’ or ‘non‐polar’ or ‘in‐between’ group, which accounts for 2.5 billion people worldwide, may be above the average poverty line for developing countries but in all likelihood is still at risk of experiencing poverty. This article outlines indicative data on trends relating to poverty and the non‐poor by different expenditure groups and critically reviews the recent literature that contentiously labels such groups as ‘middle class’. The article argues that such groups are neither extreme poor nor in all likelihood secure from poverty and that such groups are worthy of closer examination because their expansion may potentially have wider societal implications, for example, related to taxation, governance and, ultimately, domestic politics.

Authors: Vivekanandhan Singaravelu , Misra Manjusri , Mohanty Amar Kumar 
Published: October 2012

AbstractInjection molded poly(trimethylene terephthalate) (PTT)/carbon fiber (CF) composites have been fabricated using a twin screw micro compounder. The effect of CF reinforcement on the thermal, mechanical, dynamic mechanical, and microscopic properties of the composite was investigated. Addition of 30 wt% of CF into PTT resulted in the significant enhancement of tensile (120%) and flexural (30%) strength compared to neat PTT. The rule of mixture was successfully employed for theoretical calculations of tensile modulus and the calculated values were compared with the experimental results. Similarly, CF reinforced (30 wt%) PTT composites exhibited an increase of more than a 150°C in the heat deflection temperature. Scanning electron microscopy analysis of the tensile fracture specimens revealed uniform distribution of the CFs with good polymer matrix and fiber adhesion. Overall, the results obtained indicate the enhancement of properties with increasing fiber content, confirming better fiber and polymer matrix compatibility. POLYM.

Published: October 2012

AbstractIn this paper, a novel plasmon‐enhanced photoluminescence (PL) hybrid system is presented based on metal–semiconductor nanostructure, in which TiO2:Sm3+ works as luminophor while the gold nanoparticle (NP) as the promoter of plasmon resonance. The plasmon‐enhanced PL is obtained by optimizing the plasmon resonance peak of gold NP employed in the system, and it is deduced that there is energy transfer from TiO2:Sm3+ to Au NPs during the process of light emitting. When the localized surface plasmon resonance (LSPR) spectra of Au NPs overlap with the PL spectra of TiO2:Sm3+, the Au NPs absorb the energy transferred from TiO2:Sm3+, and then the plasmonic mode confined around Au NPs can be excited to bring out the PL enhancement. magnified imageSchematic illustration of the process of plasmon‐enhanced emission. The different steps are (a) light emitting of TiO2:Sm3+, (b) energy transferred from TiO2:Sm3+ to the Au NPs, and (c) enhanced emitting of the hybrid system.
Dysfunctional remembered parenting in oncology outpatients affects psychological distress symptoms in a gender‐specific manner

Published: October 2012

AbstractEvidence suggests that gender differences appear in a variety of biological and psychological responses to stress and perhaps in coping with acute and chronic illness as well. Dysfunctional parenting is also thought to be involved in the process of coping with stress and illness; hence, the present study aimed to verify whether dysfunctional remembered parenting would influence psychological distress in a gender‐specific manner in patients suffering from cancer. Patients attending an outpatient oncology clinic completed the Remembered Relationships with Parents (RRP), Hospital Anxiety and Depression and Spielberger's State–Trait Anxiety Inventory scales and the National Cancer Center Network Distress Thermometer. Although no baseline gender differences were detected, a multivariate analysis confirmed that anxiety and depression symptoms of men and women suffering from cancer are differentially affected by the RRP Control and Alienation scores. Women with remembered parental alienation and overprotection showed significantly more anxiety symptoms than men, whereas men were more vulnerable to remembered alienation than overprotection with regard to the Distress Thermometer scores. These results suggest that remembered dysfunctional parenting is crucially, and in a gender‐specific manner, involved in the coping strategy adopted by male and female cancer patients.

AbstractObjectivesTo evaluate the feasibility of completing in one session a second‐trimester ultrasound scan in obese pregnant women, to compare the quality of images obtained with those of non-obese women and to analyze factors that can improve the completion rate.MethodsThis prospective study, from 2009 to 2011, included all obese pregnant women (prepregnancy body mass index (BMI) > 30 kg/m2) who had an ultrasound examination at 20–24 weeks in our department, and a control group of pregnant women with normal BMI (20–24.9 kg/m2) who had the same examination. A single operator reviewed the standardized ultrasound images (three biometric and six to assess key anatomical features) required under French guidelines, to assess their presence, evaluate the quality of all images and score the quality of the six anatomical images. Each image was assessed according to between four and six criteria, each worth one point. We sought excellent quality, defined as the frequency of maximum points for a given image type. The factors associated with completing the scan in one session were evaluated with multivariate logistic regression.ResultsThe obese group included 223 women and the control group 60; a complete scan in one session was achieved in 70.4% and 81.7% of these, respectively (P = 0.08). The completion rate for each image type was at least 95% in the control group and 90% in the obese group, except for diaphragm and right outflow tract images. Significant factors associated with completing the scan in the multivariate model were: having 10 additional minutes for the scan (P = 0.03), moving the fetus so that the back was in posterior or lateral position (P = 0.01), more experienced sonographer (P = 0.03) and thinner maternal abdominal wall thickness (P = 0.01). Overall, the excellence rate varied from 35% to 92% in the normal BMI group and from 18% to 58% in the obese group, and was significantly lower in the latter for all images except abdominal circumference (P = 0.26) and spine (P = 0.06). Anatomical quality scores were also significantly lower in the obese group (22.3 vs 27.2; P = 0.001).ConclusionAlthough ultrasound scans of obese pregnant women are feasible, image quality and global anatomical scores are significantly lower among obese than normal‐weight women. However, certain simple improvements may increase fetal visualization.
Dynamics of cognition
Authors: Riley Michael A. , Holden John G. 
Published: October 2012

AbstractThe application of dynamical systems methods and concepts to cognitive phenomena has broadened the range of testable hypotheses and theoretical narratives available to cognitive scientists. Most research in cognitive dynamics tests the degree to which observed cognitive performance is consistent with one or another core phenomena associated with complex dynamical systems, such as tests for phase transitions, coupling among processes, or scaling laws. Early applications of dynamical systems theory to perceptual‐motor performance and developmental psychology paved the way for more recent applications of dynamical systems analyses, models, and theoretical concepts in areas such as learning, memory, speech perception, decision making, problem solving, and reading, among others. Reviews of the empirical results of both foundational and contemporary cognitive dynamics are provided.WIREs Cogn Sci2012. doi: 10.1002/wcs.1200This article is categorized under:Neuroscience > Cognition
Morphology and distribution of the external labial sensilla in Fulgoromorpha (Insecta: Hemiptera)
Authors: Brożek Jolanta , Bourgoin Thierry 
Published: October 2012

AbstractThe present paper describes the sensory structures on the apical segment of the labium in fifteen fulgoromorphan families (Hemiptera: Fulgoromorpha), using the scanning electron microscope. Thirteen morphologically distinct types of sensilla are identified: five types of multiporous sensilla, four types of uniporous sensilla and four types of nonporous sensilla. Three subapical sensory organ types are also recognized, formed from one to several sensilla, each characteristic of a family group. Sensilla chaetica (mechanoreceptive sensilla) fall into three categories dependent on length and are numerous and evenly distributed on the surface of the labium except where they occur on specialized sensory fields. The planthopper morphological ground plan is represented by two apical pair of sensory fields (dorsal and ventral) on which 11 dorsal pairs of sensilla (10 peg-like pairs + 1 specialized pair dome or cupola-like) and 2 ventral pairs of sensilla basiconica occur. Two main patterns (cixiid and issid) together with more specialized ones (derbid, lophopid, flatid and fulgorid) are reported. Disparity and diversity of the sensory structures are analyzed from a taxonomic and functional perspective. A gustatory function is provided for several chemoreceptive labial sensilla, as in the antennal flagellum sensilla in some other Hemiptera. This represents a more recently evolved function for the planthopper labium. Finally, further lines of study are suggested for future work on the phylogeny of the group based on the studied characters.
