This paper proposes a novel multiple emotion recognition scheme from facial expressions which is able to understand a combination of different emotions using active appearance model (AAM), k-nearest neighbour (k-NN) and the proposed classification model in mobile environments. The proposed method classifies five basic emotions (normal, happy, sad, angry, and surprise) and ambiguous facial emotions by weighted combining of the basic emotions in real time. Whereas most previous researches of emotion recognition identify various kinds of single emotion, this work recognises various multiple emotions with combination of five basic emotions. To evaluate the performance of the proposed method, we can achieve the best 93% accuracy in recognising the emotion. The experimental results show that the proposed method effectively performed well over the recognition of facial emotion, and the obtained result indicates the good performance enough to be applicable to mobile environments.

This study investigates factors that influence adoption and use of smartphones among Koreans and seeks to integrate two theoretical approaches: the technology acceptance model (TAM) and the uses and gratifications (U&G) approach. To that end, the study used data from a self-reported survey of 491 Korean adults who use Apple's iPhone. A structural equation model employed in the current study demonstrates that Koreans' smartphone use is affected more by motivations based on instrumental and goal-oriented use than by ritualized and less-goal oriented use. The findings suggest that to spread information system with innovative and active features, developers should pay attention to users' intrinsic motivations as well as to their extrinsic perceptions. © 2013 Published by Elsevier Ltd.

The influence of the ratio of soluble dietary fiber (SDF) and insoluble dietary fiber (IDF) on the in vitro starch digestion, predicted glycemic index (pGI), and the physicochemical properties of fiber-enriched cakes were evaluated. The hydration and pasting properties were affected by the ratio of SDF and IDF. According to the increase of IDF ratio (SDF ratio reduction) in 3. g fiber-enriched cakes, slowly digestible starch (SDS) contents increased, while the rapidly digestible starch (RDS) contents decreased. The pGI values were significantly different with control in 3. g fiber-enriched cake containing more than 50% IDF contents (p< 0.05). But the pGI values of 6. g fiber-enriched cake samples were not significantly different by SDF and IDF ratio. With the exception of the SDF 100% cake, volume index, hardness, and color values of the fiber-enriched cakes increased according to reductions in the SDF ratio. The cakes containing 3. g of total dietary fiber (the same ratio of SDF and IDF) per serving were shown to have low pGI and acceptable quality attributes. Specially, total dietary fiber amount and IDF ratio are more effective than SDF ratio to lower the pGI value. © 2013 Elsevier B.V.

Background: Health management or health promotion programs are limited, particularly for workers in small-sized industries. Objectives: This study aimed to identify the 10-year cardiovascular disease (CVD) risk using the general Framingham Risk Score and examine predictors of CVD risk adjusted for age among male workers. Methods: Routine health screening data and self-reported questionnaires were collected from 12 933 male workers in 1041 industries from 2009 to 2011 in South Korea. Results: The proportion of high CVD risk (Framingham Risk Score >20%) was 7.1% (n = 919). Most (83.5%) subjects were manufacturing workers, engaged in manual labor, with a mean (SD) age of 42.1 (9.2) years (range, 30-70 years). Younger workers were more likely to smoke cigarettes, drink alcohol heavily, and be physically inactive. A logistic regression analysis showed that after adjusting for age, occupation type, body mass index, physical activity, and alcohol consumption were significant predictors of 10-year CVD risk. Conclusion: To reduce CVD risk, education regarding lifestyle modification should be emphasized for small-sized industrial workers who are overweight, physically inactive, and heavy alcohol drinkers and who work as bus or taxi drivers. Careful attention is also needed for younger workers who are a latent risk group for the development of CVD. Copyright © 2015 Wolters Kluwer Health, Inc. All rights reserved.

Complex harmonic analysis for rotor systems has been proposed from the strict complex modal analysis based upon Floquet theory. In this process the harmonic balance method is adopted, effectively associated with conventional eigenvalue analysis. Also, the harmonic coefficients equivalent to dFRFs in harmonic mode has been derived in practice. The modes are classified from identifying the modal characteristics, and the adaptation of harmonic balance method has been proven by comparing the results of the stability analyses from Floque theory and the eigen analysis. The modal features of each critical speed are depicted in quantitatively and qualitatively by showing that the strengths of each component of the harmonic coefficients are estimated from the order of magnitude analysis according to their harmonic patterns. This effectiveness has been verified by comparing with the numerical solutions. © 2015, The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

The optical band gap energy for SrTiO3 by reduction at high temperature was 3.15 eV. The reflectivity of reduced SrTiO3 single crystals showed little variation, however, the reflectivity by the reduction condition had no effect. For the phonon mode at about 790 cm-1, a blue-shift took place upon N2 reduction and the decreased. However, a red-shift took place upon a H2-N2 reduction and the increased at the same phonon mode. With decreasing temperature the dielectric constant decreased rapidly. The thermal activation energies were 0.92-1.02 eV.

This paper investigated the trench process, unified field limit ring, and other products for the development of a 500 V-level unified trench gate power MOSFET. The optimal base chemistry for the device was found to be SF6. In SEM analysis, the step process of the trench gate and field limit ring showed outstanding process results. After finalizing device design, its electrical characteristics were compared and contrasted with those of a planar device. It was shown that, although both devices maintained a breakdown voltage of 500 V, the Vth and on-state voltage drop characteristics were better than those of the planar type. © 2016 KIEEME.

Not only has there been a growth in the utilisation of non-standard workers in South Korea in recent years, but a qualitative shift has also occurred in the nature of contracting practices. This article attempts to improve understanding of this trend by shedding light on the contradictory nature of the contracting system, while also addressing problems associated with the deployment of an external labour force with fewer employment entitlements on user-firm sites, and the implications of these phenomena for employment practices and workers' rights. © The Author 2014.

In this paper, we have analyzed the electrical characteristics of 1200V trench gate field stop IGBT and have compared to NPT planar type IGBT and NPT planar field stop IGBT. As a result of analyzing, we obtained superior electrical characteristics of trench gate field stop IGBT than conventional IGBT. To begin with, the breakdown voltage characteristic was showed 1,460 V and on state voltage drop was showed 0.7 V. We obtained 3.5 V threshold voltage, too. To use these results, we have extracted optimal design and process parameter and designed trench gate field stop IGBT. The designed trench gate IGBT will use to inverter of renewable energy and automotive industry. © 2016 KIEEME. All rights reserved.
