      • Radical Fashion and Radical Fashion Innovation

        Dan Zhang,C,Anthony Di Benedetto 한국마케팅과학회 2010 Journal of Global Fashion Marketing Vol.1 No.4

        This is a study of the related concepts of radical fashion and radical fashion innovation. Radical fashions are defined here as those that may never enter the market at all, and exist primarily on runway shows, in exhibitions and in publicityby contrast, radical fashion innovations may be very successful in the marketplace. Radical fashions represent a clear break from the old designs, as opposed to incremental fashions, which are defined as an extension or evolution of the old designs. Using this definition, radical fashion seems to be at odds with the definition of marketable fashion. Nevertheless, while most radical fashions do not enter the market at all and live only in runway shows, exhibitions, and museums, there are many examples of radical fashion innovations successful in the market. Accordingly, a series of questions rise: What is radical fashion? What is radical fashion innovation? What are the differences and similarities between these, and how are they connected? This study seeks to address these questions, using a foundation developed in the radical product innovation literature. Fashion innovations may be in terms form or function, or style, and can be radical(involving the breaking down of old ideas) or incremental (involving the evolution of new ideas from old ideas). We draw from the radical product innovation literature to build two related models. The first is a model of radical fashion and radical fashion innovation that illustrates the components of both concepts. The second is a model of radical fashion innovation diffusion, drawn from the general product innovation diffusion literature, which explores the evolution of and the connections between these two concepts from the beginning (i.e., the radical fashion) to the end (i.e., success in the mass market). Radical fashion may result in designs that are more suitable for the runway, catalogues, or even museum display, than for actual wear. Radical fashion has sometimes been called “new ideas before their marketing phase.” Radical fashion may successfully enter the market, however, and gain wide acceptance among consumers. The transition from radical fashion to radi- 1) Ph. D.

Notable in this transition process is the fact that, for many product innovations, what drives the first customers to purchase (the “Visionaries,” to use Moore’s terminology in his “crossing the chasm” model of innovation diffusion) may be very different from what drives the rest of the market (the “Pragmatists.”). If this “chasm” or divide between the two market segments is not recognized, the innovating firm may find that their product stalls during the diffusion process and never effectively reaches the mass market. In the case of fashion products, visionaries (such as celebrities and the fashion press) prime the market and create favorable word of mouthyet, at the same time, less-radical, wearable designs may be seen on the runway, or may be manufactured for the mass market and sold through department stores, specialty clothing stores, or even discounters. The most successful worldwide designers instinctively know this, and can continuously produce radically innovative fashion which also usually transitions to the mass market successfully.

        Dengue Virus is Hyperendemic in Nigeria from 2009 to 2020: A Contemporary Systematic Review

        Anthony Uchenna Emeribe,Idris Nasir Abdullahi,Idongesit Kokoabasi Isong,Anthony Ogbonna Emeribe,Justin Onyebuchi Nwofe,Buhari Isa Shuaib,Abubakar Muhammad Gwarzo,Yahaya Usman,Madjid Sadi,Chikodi Modes 대한감염학회 2021 Infection and Chemotherapy Vol.53 No.2

        Backround: Data on Dengue virus (DENV) infection prevalence, geographic distribution and risk factors are necessary to direct appropriate utilization of existing and emerging control strategies. This study aimed to determine the pooled prevalence, risk factors of DENV infection and the circulating serotypes within Nigeria from January 1, 2009 to December 31, 2020. Materials and methods: Twenty-one studies out of 2,215 available articles were eligible and included for this systematic review. Relevant articles were searched, screened and included in this study according to the Preferred Reporting Items for Systematic reviews and MetaAnalyses (PRISMA) criteria. The risk of bias in primary studies was assessed by Cochrane's method. Heterogeneity of pooled prevalence was calculated using the chi-square test on Cochrane's Q statistic, which was quantified by I-square values. The random-effects analyses of proportions were used to determine the pooled prevalence of DENV antibodies, antigen and RNA from eligible studies. Results: Of these, 3 studies reported co-circulation of all the 4 serotypes, while 2 separately reported co-circulation of DENV-1 &2 and DENV-1 to -3. All the antibody-based studies had significantly high heterogeneity (I2 >90%, P <0.05), while the NS1 and PCR-based studies had low heterogeneity (I2 <25%, P >0.05). The pooled prevalence of DENV IgM, IgG, RNA, NS1 and neutralizing antibodies were 16.8%, 34.7%, 7.7%, 7.7% and 0.7%, respectively. Southeast Nigeria had the highest pooled DENV-IgG seropositivity, 77.1%. Marital status, gender, educational level and occupation status, the proximity of residence to refuse dumpsite, frequent use of trousers and long sleeve shirts were significantly associated with DENV IgG seropositivity (P <0.05). Conclusion: Based on these findings, it can be inferred that Nigeria is hyperendemic for Dengue fever and needs concerted efforts to control its spread within and outside the country.

        비예혼합 대향류화염의 구조와 소화

        Anthony Hamins,Park,Woe-Chul 한국화재소방학회 2003 한국화재소방학회논문지 Vol.17 No.3

        화염변형률과 소화약제의 첨가 및 부력이 비예혼합 대향류 화염의 구조와 소화에 미치는 영향을 조사하기 위해 필라멘트와 열전대를 이용한 실험과 Oppdif 및 FDS를 사용한 수치해석을 수행하였다. 소화농도에 가까운 메탄-공기의 확산화염에 대하여 2.2초의 무중력 낙하실험과 정상중력에서의 측정결과를 수치모사의 결과와 비교하였다. 변형률 7 s<TEX>$^{-1}$</TEX>에서 100 s<TEX>$^{-1}$</TEX>까지 무중력상태에서 측정한 임계소화농도로부터 질소의 임계소화농도에 최대치가 있음을 확인하였다. 또한, 부력의 효과, 즉, 화염의 곡률과 두께 변화를 FDS의 계산결과로 확인하였다. 무중력상태에서 화염의 최고온도와 그 위치에 대한 실험치와 계산값이 일치함을 알 수 있었다. Measurements with filaments and thermocouples and computations with Oppdif and FDS were carried out to investigate the impact of flame strain, agent addition, and buoyancy on the structure and extinction of nonpremixed counterflow flames. Measurements through 2.2 s drop tests in microgravity conditions and experiments in normal gravity conditions were compared with the results of computations. For the global strain rates 7 s<TEX>$^{-1}$</TEX> through 100 s<TEX>$^{-1}$</TEX> , the turning point behavior in the critical nitrogen concentration at O-g was confirmed. The effects of buoyancy, that is, changes in the flame curvature and thickness were also confirmed by the computations with FDS. There was agreement in the peak flame temperature and its position between the computations and the measurements in the near extinction methane/air diffusion flames in microgravity.

        Collaborative Framework of Algorithms for Sparse Channel Estimation in OFDM Systems

        Anthony Ngozichukwuka Uwaechia,Nor Muzlifah Mahyuddin 한국통신학회 2018 Journal of communications and networks Vol.20 No.1

        For proper matrix ensembles, it has been known that thegreedy pursuit (GP) algorithms are computationally efficient andfast to reconstruct sparse signals from far fewer linear measurements. In considering several parameters such as sparsity level,sparse signal ambient dimension and the number of linear measurements,the GP algorithms have been shown to perform differentlyin estimating sparse signals. According to data fusion principle,fusing completely the estimated support set of different reconstructionalgorithms can improve signal recovery performance. Itcan, however, lead to the increased probability of estimating incorrectsupport indices, and thus degrades the signal reconstructionaccuracy. In this paper, a new fusion framework, namely collaborativeframework of algorithms (CoFA), is proposed to pursueaccurate reconstruction of the sparse signals from far fewerlinear measurements. The two main ingredients of the proposedscheme that control the estimation of incorrect support indices arepre-selection support of orthogonal matching pursuit (OMP) algorithmand Thresholding -to eliminate unpromising indices fromthe identied support set of any participating algorithm. Using therestricted isometry property, the theoretical analysis of the CoFAscheme and the sufficient conditions (guarantees) for realizing animproved reconstruction performance are presented. Simulationresults demonstrate that the proposed scheme is effective and offera better channel estimation performance in terms of meansquared-error (MSE) and bit-error-rate (BER) when compared toother reconstruction algorithms, without the significant increase incomputational complexity.

      • Helicobacter pylori and Gastric Cancer Recent Update From Gastritis To Cancer

        ( Anthony Axon ) 대한소화기학회 2007 SIDDS Vol.9 No.-

        Helicobacter pylori infects around 50% of the worlds population. It is usually transmitted in childhood and persists for the whole of life. The severity and pattern of the gastritis is modified by interaction between the genetic constitution of the organism and that of the host. Dietary factors may influence the severity and possibly the pattern of the inflammation. Infected individuals with a high gastric acid production develop an antral predominant pattern of gastritis whilst those with relative hypochlorhydria, corpus predominant or pan-gastritis. Patients with antral gastritis are relatively protected from developing gastric cancer, furthermore acid secretion in these individuals rises as a result of the infection. Those with severe corpus predominant gastritis progress to generalised atrophy, intestinal metaplasia and hypochlorhydria. In patients with a particularly severe and aggressive antral gastritis inflammation may gradually extend throughout the stomach to produce the same outcome. Individuals with generalised atrophy and intestinal metaplasia are most at risk of developing gastric cancer. It is uncertain whether it is the Helicobacter pylori itself or the active inflammation that it cause that is responsible for cancer or whether Helicobacter pylori merely destroys the mucosa leaving the stomach to become infected with metabolically active faecal organisms that are responsible for the final stage of carcinogenesis.
