Published: September 2015

Background—

Given the recent declines in heart attack and stroke incidence, it is unclear how women and men differ in first lifetime presentations of cardiovascular diseases (CVDs). We compared the incidence of 12 cardiac, cerebrovascular, and peripheral vascular diseases in women and men at different ages.

Methods and Results—

We studied 1 937 360 people, aged ≥30 years and free from diagnosed CVD at baseline (51% women), using linked electronic health records covering primary care, hospital admissions, acute coronary syndrome registry, and mortality (Cardiovascular Research Using LInked Bespoke Studies and Electronic Records [CALIBER] research platform). During 6 years median follow-up between 1997 and 2010, 114 859 people experienced an incident cardiovascular diagnosis, the majority (66%) of which were neither myocardial infarction nor ischemic stroke. Associations of male sex with initial diagnoses of CVD, however, varied from strong (age-adjusted hazard ratios, 3.6–5.0) for abdominal aortic aneurysm, myocardial infarction, and unheralded coronary death (particularly >60 years), through modest (hazard ratio, 1.5–2.0) for stable angina, ischemic stroke, peripheral arterial disease, heart failure, and cardiac arrest, to weak (hazard ratio <1.5) for transient ischemic attack, intracerebral hemorrhage, and unstable angina, and inverse (0.69) for subarachnoid hemorrhage (all
P
<0.001).

Conclusions—

The majority of initial presentations of CVD are neither myocardial infarction nor ischemic stroke, yet most primary prevention studies focus on these presentations. Sex has differing associations with different CVDs, with implications for risk prediction and management strategies.

New or little known epiphyllous liverworts, VI. Papillolejeunea gen. nov. from Papua New Guinea

Authors: Pócs Tamas
Published: September 2015

A new epiphyllous Lejeuneaceae genus, Papillolejeunea is described. It is a segregate of Lejeunea, characterized by a large, 2-4 celled, stout, papilla like first (distal) tooth on a well developed, inflated lobule, while the second (proximal) tooth is reduced, blunt, hidden with the usually involuted free lobule margin. Four new species are described within the genus. One, Papillolejeunea balazsii, forms the Section nov. Papillolejeunea and the type of the genus, characterized by large number of serially arranged mucilage cells on the dorsal surface and margin of the lobe, at the margin of amphigastria and on the perianth keels. Three further species, Papillolejeunea candida, Papillolejeunea papuana and Papillolejeunea touwii constitute the Section nov. Candidae, where no such dorsal and marginal glands occur. The distribution of the genus seems to be restricted to the mountainous area of New Guinea.

Examination of Empirical Evidence of Organic Growth Strategy a Study on Indonesia Public Listed Companies
Authors: Sadeli Ferdinand
Published: September 2015

The main objective of this research is to re-examine and adjust the original model of Organic Growth Index (OGI), developed by Ref. [9] and applied into Indonesian public listed companies with earnings generated organically rather than through income manipulation, financial engineering,
or through mergers and acquisitions (M&A). As this original model excludes banks, financial institutions, REITs and insurance companies, the OGI assessment need to be adjusted to include those sectors. This research modified the first step of OGI, by applying residual income (RI) instead
of economic value added (EVA) to avoid the complexity of EVA calculation for financial institutions and REITs companies. This research compares the result with the reference research16 which has initially applied the OGI analysis towards the Indonesia public listed companies. Their
research based on 70 samples were taken from Kompas 100 Stock Index from the period of 2004 to 2007 which also exclude financial institutions companies. This research has used similar objects comprises of Kompas 100 companies, nonetheless through OGI modification with objective of including
banks, financial institutions and insurance companies, covered period from 2008 to 2012, albeit interval of 5 years, consistent with original OGI. The OGI model designed to explain value-creating companies that have consistently outperformed industry competition through organic growth. The
original test begins by selecting the best EVA which is modified into RI model to accommodate the assessment of financial institutions companies. The result of this study shows that there are only 2 percent of Indonesian public listed companies identified as OGI winners, significantly less
than the previous Waworuntu and Tjhatra’s research of 10% and also less than previous Hess study. This study also indicated that more Indonesian public companies actively involved in M&A activities.

Authors: Briliana Vita , Wahid Nabsiah Abdul , Fernando Yudi
Published: September 2015

Motivation-Opportunity-Ability (MOA) theory and Social Identity (SI) theory have been used separately as theories that predict the customer-to-customer online know-how exchange (C2C) or e-WOM behavior. By integrating both theories in one framework, this study investigates whether motivation,
opportunity, ability and social identity (MOASI) act as predictor for customer-to-customer online to know how to exchange (C2C). Analyzed data from an online survey on 355 batik online community members of a BlackBerry Messenger Group using Structural Equation Modeling (SEM) revealed that
only MOA fits very well as a predictor of C2C. In addition, ability is found to be the highest influencer on C2C followed by motivation, opportunity and social identity. The findings imply the importance of MOA as important predictors to a C2C behavior which should not be avoided by the Indonesian
batik fashion industry e-retailers when they develop specific marketing strategies and tactics to sell their products through C2C.

Is it Necessary to be a Learning Organization in Private Universities?
Authors: Anindita Rina
Published: September 2015

This research aims to observe how Knowledge Sharing level correlates with the implementation of Learning Organization in both People and Structure Levels. This topic may help those Private Universities to improve their learning capacities and transform into organizations which are able
to facilitate their members to develop learning culture so they will have adequate capacities to perform some innovations, foster the development of their organizations, and share valuable knowledge. By doing so, such organization will continuously transform (Peddler, 1998; Dale, 2003), so
it has certain capacities to perform some innovations and grow the level of its development (Watkins and Marsick, 1993, 1994, 2003). Slightly different with the above-mentioned statements, Veisi, et al. (2012) stated that the individuals or members of higher education institutions will determine
whether such institution will develop into a learning organization or not. Thus, we need to distinguish between the learning organization for individuals and for management board, eventhough those individuals, teams, and organization shall jointly establish an ‘embedded’ system
(Kumar, 2005). The findings of this research evidences that the implementation of Learning Organization in People level bring significant and positive influence towards the implementation of Learning organization in Structure level. Learning Organization in People level also gives meaningful
and positive contribution towards the level of knowledge sharing, which has been either directly or indirectly integrated through organization commitment. On the contrary, Learning Organization in Structure level does not contribute any meaningful impact towards the level of knowledge but
such component can still affect knowledge sharing when it is integrated through the organization commitment.

Eco-Philosophy for Industry Practices in Indonesia
Authors: Fios Frederikus
Published: September 2015

Eco-philosophy is a critical reflective to examine the problems that arise in the relationship between human and environment. Nowadays, we can not deny the existence of a problem that is created between the human and the environment. Humans in this paper refer to the subject or industry
practitioners in Indonesia. Then, the environment refers to the objective conditions of the affected Indonesian perpetrators of the industry in question. Human existence that industry and the environment can not be denied existence. These two elements create unfair conditions, because industries
practices often overlook the ethical values in the context of ecophilosophy. Low labor costs, the industries concentrated in Java and Sumatra, and monopolistic practices of natural resources, forests and pollution are concrete examples of industrial practice in Indonesia, which have a negative
impact on humans and the environment. Injustice on others and the environmental crisis can not be avoided. This paper provides a philosophical framework that offers alternative solutions resolve the disharmony between the world of industrial relations with our fellow human beings and the environment
in Indonesia.

Integration Analysis’ Explanatory Power Over Stock Returns: Evidence from Indonesia
Authors: Rusmanto Toto
Published: September 2015

The main purpose of this research is to identify whether integration analysis for stock returns has higher predictive power compared to technical analysis and fundamental analysis alone based on research conducted in Indonesia. To fulfill the objective, the “blue chip” Indonesian
companies are chosen. The research data period is 2007–2011 and taken quarterly. Technical analysis uses previous quarter return to predict current quarter returns. Fundamental analysis uses operating cash flow and price-to-book ratio. Integrated analysis combines these three variables
to test the combined predictive power over current quarter stock returns. The results are compared using multiple regression analysis. Change in price-to-book ratio is significant and can help predict stock returns while previous quarter returns do not have predictive power of the next quarter
returns, possibly due to the volatility in Indonesian market. Operating cash flow, while important, does not have predictive power over stock returns, possibly due to it not being an important factor in making investment decisions in Indonesia. Potential investors should understand Price-to-Book
ratio and use it in any analysis concerning stock returns. They should also be prudent not to make investment decisions based on historical stock returns. Operating cash flow-generating ability is not one of the indicators the market watches out for. Integrated analysis outperforms a purely
technical analysis, but not a purely fundamental analysis.
Effects of Dimethylamine Borane in Electroless Ni–B Plating
Authors: Rha Sa-Kyun , Baek Seung-Deok , Lee Youn-Seoung
Published: September 2015

By electroless plating in a pH 7 bath at 50 °C, Ni–B alloy films with nano-crystallite size (3∼6 nm) were formed on screen printed Ag paste. According to the addition of DMAB (dimethylamine borane), the boron concentration in the Ni–B alloy films increased systematically
from <1 at.% to ∼10 at.%, and the crystallite size of the Ni–B alloy films decreased gradually. The crystal/electronic structures of the Ni–B alloys were studied using XAS (X-ray absorption spectroscopy), XRD, etc., with changes of boron contents. In the crystalline structure,
the ordering of fcc type was broken upon alloying and then the samples with additions of 0.5 M and 1 M DMAB had amorphous-like structures with decreases of crystallite size. In the electronic structure, the unoccupied d states of the Ni sites were filled as the B concentration
increased upon alloying. From the electronegativity rule and the broken orderging upon alloying, we can suggest that an overall charge transfer occurs from the Ni sites toward the alloying B sites with intra-atomic charge redistribution, leading to an increased occupancy of the Ni 3d states
in the alloys.
Silicide/Silicon Hetero-Junction Structure for Thermoelectric Applications
Authors: Jun Dongsuk , Kim Soojung , Choi Wonchul , Kim Junsoo , Zyung Taehyoung , Jang Moongyu
Published: September 2015

We fabricated silicide/silicon hetero-junction structured thermoelectric device by CMOS process for the reduction of thermal conductivity with the scatterings of phonons at silicide/silicon interfaces. Electrical conductivities, Seebeck coefficients, power factors, and temperature differences
are evaluated using the steady state analysis method. Platinum silicide/silicon multilayered structure showed an enhanced Seebeck coefficient and power factor characteristics, which was considered for p-leg element. Also, erbium silicide/silicon structure showed an enhanced Seebeck
coefficient, which was considered for an n-leg element. Silicide/silicon multilayered structure is promising for thermoelectric applications by reducing thermal conductivity with an enhanced Seebeck coefficient. However, because of the high thermal conductivity of the silicon packing
during thermal gradient is not a problem any temperature difference. Therefore, requires more testing and analysis in order to overcome this problem. Thermoelectric generators are devices that based on the Seebeck effect, convert temperature differences into electrical energy. Although thermoelectric
phenomena have been used for heating and cooling applications quite extensively, it is only in recent years that interest has increased in energy generation.
Improvement in the Positive Bias Temperature Stability of SnOx-Based Thin Film Transistors by Hf and Zn Doping
Authors: Han Dongsuk , Park Jaehyung , Kang Minsoo , Jeon Hyeongtag , Park Jongwan
Published: September 2015

We investigated the performance of tin oxide thin film transistors (TFTs) using DC magnetron sputtering. A remarkable improvement in the transfer characteristics was obtained for the Hf-doped tin oxide (HTO) TFT. We also developed amorphous hafnium-zinc-tin oxide (HZTO) thin film transistors
and investigated the effects of hafnium doping on the electrical characteristics of the HTO TFTs. Doping with hafnium resulted in a reduced defect density in the tin oxide channel layer related to oxygen vacancies, which may result from increased field effect mobility. Zinc atoms have relatively
higher oxidation potential compared to tin atoms, so more oxygen molecules can be absorbed and more electrons are trapped in the HZTO films. The HZTO TFTs exhibited good electrical characteristics with a field effect mobility of 10.98 cm2/Vs, and a high ION/IOFF
ratio over 108.
Improvement in the Electrical Performance of Ge-Doped InZnO Thin-Film Transistor
Authors: Im Yong Jin , Kim Sang Jo , Shin Ji Hun , Ha Seung Soo , Park Chan Hee , Yi Moonsuk
Published: September 2015

We fabricated amorphous oxide semiconductor thin-film transistors (TFTs) using Ge-doped InZnO (Ge–IZO) thin films as active-channel layers. The Ge–IZO thin films were deposited at room temperature by radio-frequency (RF) magnetron co-sputtering system, and then annealed
in air for 1 h at 300 °C. Some processing parameters such as sputtering oxygen partial pressure [O2/(Ar + O2)] and sputtering power for GeO2 target were changed to investigate what was the optimal amount of Ge in the Ge–IZO active layer. A small concentration
of Ge added to IZO by co-sputtering enhanced the carrier concentration, mobility, and conductivity; but further increase in Ge concentration degraded the device performance. In order to optimize the electrical properties of Ge–IZO TFTs, we tried to adjust the processing parameters and
the best Ge–IZO TFT was obtained at a co-sputtering oxygen partial pressure of 2% and GeO2 target power of 10 W. The fabricated Ge–IZO TFT exhibited an on/off ratio of 3.0×107, a saturation mobility of 13.05 cm2/V · s, a subthreshold
swing of 0.95 V/dec, and a threshold voltage of 0 V. XPS and XRD analyses of Ge–IZO films were performed to investigate the binding energies of atoms in Ge–IZO films and the crystallinity of the films. 90% transmittance of visible light was achieved, which makes the technology
useful for transparent devices.

In this study, the electrical characteristics of Ni-CNT-SiO2-SiC structured 4H-SiC MIS capacitors were investigated. The effect of CNTs in the gate/insulator interface have been characterized by C–V measurement at 300 to 500K and J–V have also been
measured. The experimental flat-band voltage tends to change with or without CNTs. Current densities of both devices are observed a negligible difference up to 3 V. It has been found that adding CNTs and/or change of temperature can help to control the positive and/or negative flat-band voltage
shift.

Published: September 2015

Temperature/humidity microchips with micropump were fabricated using a CMOS-MEMS process and combined with ZigBee modules to implement a sensor system in package (SIP) for a ubiquitous sensor network (USN) and/or a wireless communication system. The current of a diode temperature sensor
to temperature and a normalized current of FET humidity sensor to relative humidity showed linear characteristics, respectively, and the use of the micropump has enabled a faster response. A wireless reception module using the same protocol as that in transmission systems processed the received
data within 10 m and showed temperature and humidity values in the display.
Improving the Sound Pressure Level of Two-Dimensional Audio Actuators by Coating Single-Walled Carbon Nanotubes on Piezoelectric Films
Authors: Um Keehong
Published: September 2015

As devices for amplifying or transforming electronic signals into audible signals through electromechanical operations, acoustic actuators in the form of loudspeakers are usually solid structures in three dimensional space. Recently there has been increasing demand for mobile electronic
devices, such as mobile phones, to become smaller, thinner, and lighter. In contrast to a three dimensional audio system with magnets, we have invented a new type of flexible two dimensional device by utilizing the reverse piezoelectric effect in certain piezoelectric materials. Crystalline
piezoelectric materials show electromechanical interaction between the mechanical state and the electrically-charged state. The piezoelectric effect is a reversible process in that materials exhibiting the direct piezoelectric effect (the internal generation of electrical charge resulting
from an applied mechanical force) also exhibit the reverse piezoelectric effect (the internal generation of a mechanical strain resulting from an applied electrical field). We have adopted the plasma surface treatment in order to put coating materials on the surface of piezoelectric film.
We compared two kinds of coating material, indium tin oxide and single-walled carbon nanotube, and found that single-walled carbon nanotube shows better performance. The results showed improvement of output power in a wider range of operating frequency; for the surface resistance of 0.5 kΩ/square,
the single-walled CNT shows the range of operating frequency to be 0.75–17.5 kHz, but ITO shows 2.5–13.4 kHz. For the surface resistance of 1 kΩ/square, single-walled CNT shows the range of operating frequency to be 0.81–17 kHz, but ITO shows it cannot generate audible
sound.

Published: September 2015

In this study, we prepared solution-based In–Ga–ZnO thin film transistors (IGZO TFTs) having a multistacked active layer. The solution was prepared using an In:Zn = 1:1 mole ratio with variation in Ga content, and the TFTs were fabricated by stacking layers from the prepared
solutions. After we measured the mobility of each stacked layer, the saturation mobility showed values of 0.8, 0.6 and 0.4 (cm2/Vs), with an overall decrease in electrical properties. The interface formed between the each layers affected the current path, resulting in reduced electrical
performance. However, when the gate bias VG = 10 V was applied for 1500 s, the threshold voltage shift decreased in the stack. The uniformity of the active layer was improved in the stacked active layer by filling the hole formed during pre-baking, resulting in improved device
stability. Also, the indium ratio was increased to enhance the mobility from 0.86 to 3.47. These results suggest high mobility and high stability devices can be produced with multistacked active layers.
An Investigation of Gate Pulse Induced Degradation in a-InGaZnO Thin Film Transistors

Published: September 2015

We investigated the effects of pulsed gate bias on degradation of amorphous indium gallium zinc oxide (a-InGaZnO) thin film transistors (TFTs). The waveform composed of 0 V and 20 V produced little degradation, but the waveform composed of −20 V and 0 V produced a considerable
degradation on the turn-on current in the transfer characteristics. Those instabilities were found mostly in TFTs of which the concentration of Zn is higher than the other metallic components (In, Ga). In order to explain the anomalous degradation behaviors, we propose a possible degradation
model which is different from the conventional model of charge trapping. Our proposed model is related to an increase of acceptor-like states in a-InGaZnO near the source and drain electrodes. More electrons can be trapped there, and the increased potential barrier hinders current flow in
the channel. The proposed model can also account for the increased frequency dispersion in C–V characteristics of our a-InGaZnO TFTs after the waveform stress.

Published: September 2015

Four novel thermally activated delayed fluorescence (TADF) materials with 9,10-dihydro-9,9- dimethylacridine (DMAC) and phenylindolo(2,3-a)carbazole (PIC) as electron donors and benzazole derivatives (BO, and BT) as electron acceptors (DMAC-BO, DMAC-BT, PIC-BO, and PIC-BT) were designed
and theoretically investigated for use as a blue organic light emitting diode (OLED) emitter. Using density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations, we calculated the electron distribution of the highest occupied molecular orbital (HOMO) and
the lowest unoccupied molecular orbital (LUMO), and the energy of the lowest singlet (S1) and the lowest triplet (T1) excited states. All the dyes had a small spatial overlap between the HOMO and LUMO because of the relatively large dihedral angle between
the phenyl ring and the acceptor moiety. In terms of the energy difference (ΔEST) between the S1 state and the T1 state, DMAC-BO and DMAC-BT showed the small ΔEST (0.18 eV and 0.21 eV, respectively). However, PIC-BO and
PIC-BT showed the large ΔEST (0.62 eV and 0.61 eV, respectively). Among the TADF materials, we showed that DMAC-BO would have the best TADF properties in terms of small ΔEST and blue OLED emitters
Efficiency Enhancement of Tandem Organic Light-Emitting Devices Fabricated Utilizing an 1,4,5,8,9,11-Hexaazatriphenylene-Hexacarbonitrile Charge-Generation Layer
Authors: Jeon Young Pyo , Kim Tae Whan
Published: September 2015

The electrical and the optical properties of tandem organic light-emitting devices (OLEDs) with stacked electroluminescence units were investigated to clarify the charge-generation mechanisms due to the existence of a charge-generation layer (CGL). The current density of the current
limited devices with an 1,4,5,8,9,11-hexaazatriphenylene-hexacarbonitrile (HAT-CN) CGL was 35% higher than that of devices with a tungsten-oxide (WO3) CGL. The maximum current density of the current limited devices with a HAT-CN CGL was as high as 259 mA/cm2. The brightness
of the tandem OLEDs with a HAT-CN CGL was 15% higher than that of the tandem OLEDs with a WO3 CGL due to an increase in the current density. The charge-generation mechanisms of tandem OLEDs with a CGL were described on the basis of the experimental results.
