Bobby Swar,Gohar Feroz Khan 한국정보사회학회 2012 정보사회와 미디어 Vol.- No.23
Hallyu the popular South Korean wave of pop, drama and movies compared with world biggest entertainment industries like Hollywood and Bollywood has successfully spread into the global market in a short span of time. Recently, however there is a general skepticism regarding Hallyu’s continuing success overseas related with its general popularity. In this regard this study investigates and compares the online popularity of Hallyu in the international context and further compares it’s online popularity with Hollywood and Bollywood entertainment industries. The online popularity is investigated through webometrics from the perspective of entropy and the web. The data are obtained through the search engine called Bing.com for exploring the Hallyu entertainment industry in the international context and comparing it with Hollywood and Bollywood. The result reveals that Hallyu online popularity in terms of web presence has decreased over the time as compared with Hollywood and Bollywood entertainment industries but Hallyu has successfully integrated into the entertainment industry network in the web.

Microrobots have been demonstrated to have the potential in medical approaches, such as for targeted drug delivery. However, real-time tracking and imaging are still one of the major issues faced by microrobots. Here, we fabricated helical microrobots based on self-folding technique, and we performed double coating of gold nanoparticles (AuNPs) to the surface of microrobots to enhance the image quality under X-ray. The result shows that, we successfully coated the AuNPs into the self-rolled microrobots, and it increases the image quality when compared to non-coated microrobots. Despite the fact that there still remain some challenges to achieve successful applications of microrobots, we believe that the potential of this study can contribute to reduce the challenges faces in the medical microrobot fields.

An integrated approach has been applied to predict and optimize multi-performance characteristics, such as optimum thrust force (Fz), torque (Mz), hole surface roughness (Ra), delamination (D) and hole roundness (R), in drilling process of Kevlar fiber reinforced polymer. The experiments were performed by varying drill point geometry and drilling process parameters, i.e., drill point angle, feed rate, and spindle speed. The quality characteristics Fz, Mz, Ra, D, and R were the smaller the better. Taguchi orthogonal array (OA) L18 was used as the design of experiments. Grey fuzzy analysis was first applied to obtain a rough estimation of the optimum drill point geometry and drilling process parameters. Backpropagation neural network (BPNN) model was developed and utilized to predict the optimum Fz, Mz, Ra, D, and R. Genetic algorithm (GA) was performed to search for global optimum of drilling process parameters combinations. The analysis of the effect of drill point angle, as well as drilling process parameters, on the individual performance characteristics was conducted by examining both the percentage contribution of drill point geometry and drilling process parameters on the total variance of three responses individually, and the response graphs. The results of the confirmation experiment showed that the BPNN based GA optimization method could accurately predict and also significantly improve the multiple performance characteristics.
The Effects of Informational Complexity and Working Memory on Problem-Solving Efficiency
Bobby Hoffman,Matthew T. McCrudden,Gregory Schraw,Kendall Hartley 서울대학교 교육연구소 2008 Asia Pacific Education Review Vol.9 No.4
This study investigated the influence of informational complexity and working memory capacity oil problem-solving efficiency, We examined two predictions of the situational efficiency hypothesis, which states efficiency of problem solving varies as a function of situational constraints. One prediction is that informational complexity affects problem-solving efficiency. A second prediction is that working memory capacity affects problem-solving efficiency. Students completed a working memory task and solved abstract and concrete syllogisms. Participants solved abstract syllogisms more accurately than concrete syllogisms and spent more time solving abstract syllogisms. Thus participants demonstrated greater problem-solving efficiency when solving concrete syllogisms. Results indicate that there is a trade-off between problem-solving accuracy and problem-solving time when information differs with respect to informational complexity, a phenomenon we refer to as the efficiency paradox. Working memory capacity did not affect accuracy or efficiency. The results support the conclusion that problem-solving efficiency is situational and a function of the complexity of information. Educational implications and directions for future research are suggested.

Objective Familial hypercholesterolaemia (FH) variant positive subjects have over double the cardiovascular risk of low-density-lipoprotein-cholesterol (LDL-C) matched controls. It is desirable to optimise FH variant detection. Methods We identified 213 subjects with FH gene panel reports (LDLR, APOB, PCSK9, and APOE) based on total cholesterol >310 mg/dL; excluding triglycerides >400 mg/dL, cascade screening, and patients without pre-treatment LDL-C recorded. Demographic, clinical and lipid parameters were recorded. Results A 31/213 (14.6%) patients had pathogenic or likely pathogenic FH variants. 10/213 (4.7%) had variants of uncertain significance. Compared with patients without FH variants, patients with FH variants were younger (median age, 39 years vs. 48 years), had more tendon xanthomata (25.0% vs. 11.4%), greater proportion of first degree relatives with total cholesterol >95th percentile (40.6% vs. 16.5%), higher LDL-C (median, 271 mg/dL vs. 236 mg/dL), and lower triglycerides (median, 115 mg/dL vs. 159 mg/dL). The Besseling et al. model (c-statistic 0.798) improved FH variant discrimination over Friedewald LDL-C (c-statistic 0.724), however, Dutch Lipid Clinic Network Score (DLCNS) did not (c-statistic 0.665). Sampson LDL-C (c-statistic 0.734) had similar discrimination to Friedewald. Conclusion Although tendon xanthomata and first degree relatives with high total cholesterol >95th percentile were associated with FH variants, DLCNS or Simon Broome criteria did not improve FH detection over LDL-C. Sampson LDL-C did not significantly improve discrimination over Friedewald. Although lower triglycerides and younger age of presentation are positively associated with presence of FH variants, this information is not commonly used in FH detection algorithms apart from Besseling et al.
The HCARD Model using an Agent for Knowledge Discovery
Gerardo Bobby D.,Lee Jae-Wan,Joo Su-Chong Korea Association of Information Systems 2005 情報시스템硏究 Vol.14 No.3
In this study, we will employ a multi-agent for the search and extraction of data in a distributed environment. We will use an Integrator Agent in the proposed model on the Hierarchical Clustering and Association Rule Discovery(HCARD). The HCARD will address the inadequacy of other data mining tools in processing performance and efficiency when use for knowledge discovery. The Integrator Agent was developed based on CORBA architecture for search and extraction of data from heterogeneous servers in the distributed environment. Our experiment shows that the HCARD generated essential association rules which can be practically explained for decision making purposes. Shorter processing time had been noted in computing for clusters using the HCARD and implying ideal processing period than computing the rules without HCARD.
Swift heavy ion induced capacitance and dielectric properties of Ni/n-GaAs Schottky diode
A. Bobby,N. Shiwakoti,P.M. Sarun,S. Verma,K. Asokan,B.K. Antony 한국물리학회 2015 Current Applied Physics Vol.15 No.11
The in-situ capacitance and dielectric properties of 25 MeV C4þ ion irradiated Ni/n-GaAs Schottky barrier diode (SBD) were studied at 100 kHz in the fluence range 5 × 1010 - 5 × 1013 ions/cm2. The investigation shows reduction in capacitance and charge density with increase in ion fluence. Consequent changes were observed in other related parameters like conductance, dielectric constant, dielectric loss, loss tangent and electrical modulus. The results were interpreted in terms of generation of swift heavy ion induced acceptor trap states by electronic energy loss mechanism. Besides, the switch over characteristics of depletion to inversion regions in the CV plot reveals minority carrier recombination centers also. The dispersion and relaxation peaks observed in bias dependent dielectric plots were ascribed to the polarization and relaxation mechanism due to the interfacial trap states. The traps and recombination centers were found to alter the barrier characteristics of the fabricated SBD depending upon the ion fluence.
Biodegradation of Secondary Phase Particles in Magnesium Alloys: A Critical Review
( M. Bobby Kannan ) 한국부식방식학회(구 한국부식학회) 2016 Corrosion Science and Technology Vol.15 No.2
Magnesium alloys have been extensively studied in recent years for potential biodegradable implant applications. A great deal of work has been done on the evaluation of the corrosion behaviour of magnesium alloys under in vitro and in vivo conditions. However, magnesium alloys, in general, contain secondary phase particles distributed in the matrix and/or along the grain boundaries. Owing to their difference in chemistry in comparison with magnesium matrix, these particles may exhibit different corrosion behaviour. It is essential to understand the corrosion behaviour of secondary phase particles in magnesium alloys in physiological conditions for implant applications. This paper critically reviews the biodegradation behaviour of secondary phase particles in magnesium alloys.
