K-pop’s Art of Attention: Canadian Repercussions of the Korean Wave in Music

Judit Nagy(Judit Nagy ) 한국캐나다학회 2014 Asia-Pacific Journal of Canadian Studies (APJCS) Vol.20 No.2

The aim of the study is to examine the extent of influence the Korean wave, and within the category, K-pop has exerted on Canadian audiences. Employing transculturation theories, synthesizing socio-cultural information, and using concrete examples as illustration, the study will propose reasons for K-pop’s popularity among Canadians. It will be demonstrated that the essential hybridity of the genre, cultural policy making, Canada-bound Korean immigration, international student and tourism demographics, young Canadians’ presence in Korea as exchange students, academics or EFL teachers and the popularity of social media are all influential factors in making K-pop thrive on Canadian soil.

( Nagi A. Ibrahim ),( Basiouny A. El Gamal ) 생화학분자생물학회 2003 BMB Reports Vol.36 No.5

There has been increasing interest in studying the various effects of organophosphate insecticides in humans and experimental animals. Only a few data are available on the effect of the organophosphate insecticide, diazinon, on lipid metabolism. The aim of this study was to evaluate the effect of diazinon on plasma lipid constituents in mammalian animals. The plasma levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), and phospholipids (PL) were measured in albino rats that were orally treated with a single dose of diazinon at a level of LD_(50) or with repeated daily doses at the levels of 1/2, 1/8, and 1/32 LD_(50) for 2, 8, and 32 days, respectively. After a 24 h post-treatment with a single LD,, dose of diazinon, TC was not significantly changed, the HDL-C and PL levels were significantly decreased, but the LDL-C and TG levels were significantly increased. Separate daily oral administrations of diazinon at 1/s LD_(50), 1/8 LD_(50), and 1/32 LD,, doses resulted in a significant decrease in HDL-C and PL, with no significant change in TG. The LDL-C levels were significantly increased and TC showed no significant change with 1/2 LD_(50) and 1/32 LD, doses of diazinon, whereas change with 1/2 LD_(50) and 1/32 LD, doses of diazinon, whereas a significant decrease in the levels of TC, HDL-C, as well as LDL-C, was observed with the 1/8 DL,, dose. These data suggest that diazinon may interfere with lipid metabolism in mammals.

Region-Based Facial Expression Recognition in Still Images

Nagi, Gawed M.,Rahmat, Rahmita O.K.,Khalid, Fatimah,Taufik, Muhamad Korea Information Processing Society 2013 Journal of information processing systems Vol.9 No.1

In Facial Expression Recognition Systems (FERS), only particular regions of the face are utilized for discrimination. The areas of the eyes, eyebrows, nose, and mouth are the most important features in any FERS. Applying facial features descriptors such as the local binary pattern (LBP) on such areas results in an effective and efficient FERS. In this paper, we propose an automatic facial expression recognition system. Unlike other systems, it detects and extracts the informative and discriminant regions of the face (i.e., eyes, nose, and mouth areas) using Haar-feature based cascade classifiers and these region-based features are stored into separate image files as a preprocessing step. Then, LBP is applied to these image files for facial texture representation and a feature-vector per subject is obtained by concatenating the resulting LBP histograms of the decomposed region-based features. The one-vs.-rest SVM, which is a popular multi-classification method, is employed with the Radial Basis Function (RBF) for facial expression classification. Experimental results show that this approach yields good performance for both frontal and near-frontal facial images in terms of accuracy and time complexity. Cohn-Kanade and JAFFE, which are benchmark facial expression datasets, are used to evaluate this approach.

Graphene oxide–titanium dioxide (GO@TiO2) nanocomposite with mean diameter size of 14 nm has been fabricated, characterized, and used as photocatalyst for degradation of two highly toxic insecticides, namely carbaryl and imidacloprid. Characterizations of GO@TiO2 have been carried out using various analytical and spectroscopic techniques. Compared to TiO2NPs, the fabricated GO@TiO2 nanocomposite has advantage of its smaller band gap. The finding that the photocatalytic degradation of the examined insecticides by the fabricated GO@TiO2 is more efficient compared to that of TiO2NPs suggests the superiority for using the fabricated GO@TiO2 nanocomposite for degradation of the examined toxic insecticides.

Asymmetric Interdependence and the Selective Diversification of Supply Chains

Nagy, Stephen R.,Nguyen, Hanh World Association for Triple Helix and Future Stra 2021 Journal of Contemporary Eastern Asia Vol.20 No.2

The COVID-19 pandemic has highlighted the risks of an over-concentration of supply chains in one country. It has motivated stakeholders to pursue diversification strategies. However, a paradox exists. Stakeholders have shied away from a complete decoupling and preferring to selectively enhance economic ties with China. This article explores this paradox by examining supply chain concentration in China as a form of asymmetric interdependence and the countermeasures from the U.S., Japan, Australia, and India to minimize vulnerabilities. It argues that while the COVID-19 disruptions have brought to light the risk of supply chain overconcentration in China, countermeasures are also driven by coercive diplomacy and the deepening U.S.-China rivalry. The paper also examines the feasibility of diversification efforts by focusing on the capacity and capabilities of alternative supply chain hubs. It finds that while states are actively seeking ways to prevent China from using asymmetric interdependence of supply chains and trade to gain political leverage, there are structural limits to the degree of diversification in the short to mid-term.

Nonlinear numerical modelling for the effects of surface explosions on buried reinforced concrete structures

Nagy, N.,Mohamed, M.,Boot, J.C. Techno-Press 2010 Geomechanics & engineering Vol.2 No.1

The analysis of structure response and design of buried structures subjected to dynamic destructive loads have been receiving increasing interest due to recent severe damage caused by strong earthquakes and terrorist attacks. For a comprehensive design of buried structures subjected to blast loads to be conducted, the whole system behaviour including simulation of the explosion, propagation of shock waves through the soil medium, the interaction of the soil with the buried structure and the structure response needs to be simulated in a single model. Such a model will enable more realistic simulation of the fundamental physical behaviour. This paper presents a complete model simulating the whole system using the finite element package ABAQUS/Explicit. The Arbitrary Lagrange Euler Coupling formulation is used to model the explosive charge and the soil region near the explosion to eliminate the distortion of the mesh under high deformation, while the conventional finite element method is used to model the rest of the system. The elasto-plastic Drucker-Prager Cap model is used to model the soil behaviour. The explosion process is simulated using the Jones-Wilkens-Lee equation of state. The Concrete Damage Plasticity model is used to simulate the behaviour of concrete with the reinforcement considered as an elasto-plastic material. The contact interface between soil and structure is simulated using the general Mohr-Coulomb friction concept, which allows for sliding, separation and rebound between the buried structure surface and the surrounding soil. The behaviour of the whole system is evaluated using a numerical example which shows that the proposed model is capable of producing a realistic simulation of the physical system behaviour in a smooth numerical process.

Clinical applications and performance of intelligent systems in dental and maxillofacial radiology: A review

Nagi Ravleen,Aravinda Konidena,Rakesh N,Gupta Rajesh,Pal Ajay,Mann Amrit Kaur 대한영상치의학회 2020 Imaging Science in Dentistry Vol.50 No.2

Intelligent systems (i.e., artificial intelligence), particularly deep learning, are machines able to mimic the cognitive functions of humans to perform tasks of problem-solving and learning. This field deals with computational models that can think and act intelligently, like the human brain, and construct algorithms that can learn from data to make predictions. Artificial intelligence is becoming important in radiology due to its ability to detect abnormalities in radiographic images that are unnoticed by the naked human eye. These systems have reduced radiologists’ workload by rapidly recording and presenting data, and thereby monitoring the treatment response with a reduced risk of cognitive bias. Intelligent systems have an important role to play and could be used by dentists as an adjunct to other imaging modalities in making appropriate diagnoses and treatment plans. In the field of maxillofacial radiology, these systems have shown promise for the interpretation of complex images, accurate localization of landmarks, characterization of bone architecture, estimation of oral cancer risk, and the assessment of metastatic lymph nodes, periapical pathologies, and maxillary sinus pathologies. This review discusses the clinical applications and scope of intelligent systems such as machine learning, artificial intelligence, and deep learning programs in maxillofacial imaging.

Impact of Shading Net Color on Phytochemical Contents in Two Chili Pepper Hybrids Cultivated Under Greenhouse Conditions

Nagy, Zsuzsa,Daood, Hussein,Nemenyi, Andars,Ambrozy, Zsuzsanna,Pek, Zoltan,Helyes, Lajos Korean Society of Horticultural Science 2017 원예과학기술지 Vol.35 No.4

The objective of this study was to understand the combined effect of shading treatment and harvest time on pungency, ascorbic acid content, market-quality pepper yield, and photosynthetic activity in a yellow 'Star Flame' and 'Fire Flame' F1 hybrid pepper cultivar (Capsicum annuum). Plants were cultivated in a greenhouse under white, red, and green shading nets and compared to those grown under unshaded control conditions. The ascorbic acid and pungency parameters were analyzed by high-performance liquid chromatographic methods. Ascorbic acid, a compound of high nutritive value in pepper, was highest in fruits gathered during the first summer harvest in both hybrids. The ascorbic acid content was found to be further increased in fruits from plants grown under white net shading in both 'Star Flame' and 'Fire Flame'. Total capsaicinoid contents in 'Star Flame' were influenced by the interaction of shading treatment and harvest time (p = 0.004), with the lowest amounts ($241.2-251.5mg{\cdot}kg^{-1}$ fresh weight) resulting from white and red shading treatments at the early autumn harvest. In 'Fire Flame', both shading treatment (p = 0.009) and harvest time (p < 0.001) affected total capsaicinoid contents. We observed significantly higher total capsaicinoid contents in control fruits compared to that resulting from red and green shading treatments at the second harvest, and that resulting from red shading treatment at the third harvest. Analysis of photosynthetic activity revealed a significant and negative correlation between Fv/Fm values and total capsaicinoid contents in both hybrids (p < 0.001). Based on the obtained results, the harvest of peppers during summer should be promoted to produce fruits with high pungency.
