Delight by Design: The Role of Hedonic versus Utilitarian Benefits
Authors: Chitturi Ravindra , Raghunathan Rajagopal , Mahajan Vijay
Published: January 2019

What is the relationship between product design benefits (hedonic versus utilitarian) and the postconsumption feelings of customer delight and satisfaction? The primary insights this research provides are as follows: (1) Products that meet or exceed customers’ utilitarian needs and fulfill prevention goals enhance customer satisfaction (e.g., a car with antilock brakes and vehicle stability assist), and (2) products that meet or exceed customers’ hedonic wants and fulfill promotion goals enhance customer delight (e.g., a car with panoramic sunroof and six-speaker audio system). Furthermore, the research finds that the primary antecedent feelings of satisfaction are the prevention emotions of confidence and security provided by utilitarian benefits, whereas the primary antecedent feelings of delight are the promotion emotions of cheerfulness and excitement provided by hedonic benefits. Finally, the results show that delighting customers improves customer loyalty, as measured by word of mouth and repurchase intentions, more than merely satisfying them. The authors discuss the theoretical contribution and strategic insights the research provides for product designers and marketers.
Holistic Package Design and Consumer Brand Impressions
Authors: Orth Ulrich R. , Malkewitz Keven
Published: January 2019

This article develops empirically based guidelines to assist managers in selecting or modifying package designs for achieving desired consumer responses. Seven studies identify the key types of package designs, including the factors that differentiate those package designs, and determine how these holistic designs are related to consumer brand impressions. The selection of package designs can be simplified with the use of five holistic types: massive, contrasting, natural, delicate, and nondescript designs. Sincere brands should have natural package designs, exciting brands should have contrasting designs, competent brands should have delicate designs, sophisticated brands should have natural or delicate designs, and rugged brands should have contrasting or massive designs. The authors discuss the potential trade-offs among the impressions created by holistic design types and illustrate their findings with numerous real packages.
Customer Participation and the Trade-Off between New Product Innovativeness and Speed to Market
Authors: Fang Eric (Er)
Published: January 2019

To address the trade-off between new product innovativeness and speed to market caused by customer participation activities, the author differentiates two dimensions of customer participation—customer participation as an information resource (CPI) and customer participation as a codeveloper (CPC)—and explores the moderating effects of downstream customer network connectivity and new product development process interdependence and complexity. Matched data collected from 143 customer–component manufacturer dyads indicate that CPI has a negative influence on innovativeness when downstream customer network connectivity is high but a positive effect when it is low. In contrast, CPI has a positive effect on speed to market when downstream customer network connectivity is high and no significant effect when it is low. In addition, CPC undermines new product speed to market when process interdependence is high. In contrast, CPC can improve new product speed to market but hurt new product innovativeness when process interdependence is low. The results of this article provide specific managerial guidelines as to how to manage customer participation to improve new product innovativeness and speed to market.
Marketing under Uncertainty: The Logic of an Effectual Approach
Authors: Read Stuart , Dew Nicholas , Sarasvathy Saras D. , Song Michael , Wiltbank Robert
Published: January 2019

How do people approach marketing in the face of uncertainty, when the product, the market, and the traditional details involved in market research are unknowable ex ante? The authors use protocol analysis to evaluate how 27 expert entrepreneurs approach such a problem compared with 37 managers with little entrepreneurial expertise (all 64 participants are asked to think aloud as they make marketing decisions in exactly the same unpredictable situation). The hypotheses are drawn from literature in cognitive science on (1) expertise in general and (2) entrepreneurial expertise in particular. The results show significant differences in heuristics used by the two groups. While those without entrepreneurial expertise rely primarily on predictive techniques, expert entrepreneurs tend to invert these. In particular, they use an effectual or nonpredictive logic to tackle uncertain market elements and to coconstruct novel markets with committed stakeholders.
How Salary Receipt Affects Consumers’ Regulatory Motivations and Product Preferences
Authors: Mishra Himanshu , Mishra Arul , Nayakankuppam Dhananjay
Published: January 2019

In this article, the authors find that consumers’ preferences change as a function of their temporal distance from the receipt of their last salary. The authors propose and test that when consumers have just received their salary (“the near-salary condition”), they exhibit promotion motivations in their product preferences. However, they exhibit prevention motivations in their product preferences when significant time has elapsed since their last salary receipt (“the far-from-salary condition”). The authors collected data from two longitudinal studies to validate these findings and to test the underlying process. Using actual purchase behavior and collecting product preference during a one-month period, the authors show that consumers’ product preferences change in response to temporal distance from their last salary receipt. The findings suggest to managers that the best time to promote products or messages with a promotion appeal is near to consumers’ last salary receipt and that the best time to promote products or messages with a prevention appeal is far from consumers’ last salary receipt.

Published: January 2019

The factories of the future will be highly digitalized in order to enable flexible and interconnected manufacturing processes. Especially wireless technologies will be beneficial for industrial automation. However, the high density of metallic objects is challenging for wireless systems due to multipath fading. In order to understand the signal propagation in industrial environments, this paper provides results from a number of channel measurement campaigns funded by the German research initiative “Reliable wireless communication in the industry”. We give an overview of different measurement scenarios covering visible light communication and radio communication below 6 GHz. We analyze large and small scale parameters as well as delay statistics of the wireless channels. Finally, we discuss the importance of the results for the definition of industrial channel models.
Can uterine secretion of modified histones alter blastocyst implantation, embryo nutrition, and transgenerational phenotype?
Authors: Van Winkle Lon J. , Ryznar Rebecca
Published: January 2019

Extracellular histones support rodent and human embryo development in at least two ways. First, these molecules in uterine secretions protect embryos from inflammation caused by pathogens that gain access to the reproductive tract. Also, histones in uterine secretions likely support penetration of the uterine epithelium by blastocysts during embryo implantation. Extracellular histones seem to preserve amino acid transport system B0,+in blastocysts by inhibiting its activity. Preservation of system B0,+is needed because, at the time of invasion of the uterine epithelium by motile trophoblasts, system B0,+is likely reactivated to help remove tryptophan from the implantation chamber. If tryptophan is not removed, T-cells proliferate and reject the implanting blastocyst. Epigenetic modification of histones could alter their promotion of normal implantation through, say, incomplete tryptophan removal and, thus, allow partial T-cell rejection of the conceptus. Such partial rejection could impair placental development, embryonal/fetal nutrition, and weight gain prior to birth. Small-for-gestational-age offspring are predisposed to developing metabolic syndrome, obesity, and associated complications as adults. Shifting expression of these phenotypes might contribute to transgenerational variation and evolution. The spectrum of possible extracellular histone targets in early development warrant new research, especially since the effects of epigenetic histone modifications might be transgenerational.
Grain Policies and Storage in Southern Germany: The Regensburg Hospital (17th-19th Centuries)
Authors: Pindl Kathrin
Published: January 2019

This paper is concerned with the storage policy of the citizens’ hospital of Regensburg in the Early Modern period (focus: 18th century). The main purpose consists of (1) a source-based micro-study that helps to derive insights into the mechanisms of how experiences and expectations have influenced decisions by a pre-modern institution, (2) an analytical scheme for describing and evaluating the process of decision-making based on narrative evidence, and (3) the suggestion of analytical categories. These should allow a differentiation between time-invariant human behaviour that determines economic decisions, and time-specific factors which can be used to separate possibly “pre-modern” patterns from seemingly modern-day capitalist economic performance.
Religion and culture in Europe: law, policies and realities
Authors: Morris Paul
Published: January 2019

Is religion simply a part of culture? Can religious diversity be managed as a subset of intercultural diversity? This article explores intercultural dialogue and its relationship to “religion’ in the policies, documents and debates of the European Community. The argument is advanced that religious realities and concerns are misconstrued when religion is subsumed into culture. Religion needs to be historically and conceptually rethought and that for cultural and religious diversities to be skillfully managed in the interests of social solidarity and positive intercommunal relations both need to be addressed discretely and in tandem.

After an engagement in analytical chemistry during 50 years, I am looking back to my scientific carreer. To some extent it is based on my successful textbook in high-performance liquid chromatography. However, too much contemplation of one’s own contributions to science is boring, and it is necessary to look ahead to the future challenges in chemistry, namely to cope with the threats of climate change. And there is another topic which was and is most important in my life: mountain climbing. Its physical and maybe also mental top was to reach the summit of Mount Everest in May 2007.

Published: January 2019

A doença cárie e sua progressão estão intimamente ligados a hábitos de higiene oral e rotina alimentar, além de seus fatores etiológicos biológicos referentes à microbiota. Esta relação entre higiene oral e fatores etiológicos biológicos é a causa da doença cárie ser classificada atualmente como uma doença comportamental. O objetivo deste estudo foi verificar a representação social da doença cárie para um grupo de pais de crianças que foram atendidas em uma clínica de extensão. Esta investigação configura-se em um estudo de caso, de caráter qualitativo. Utilizou-se a entrevista semiestruturada para a coleta de dados. Os resultados mostraram que a doença cárie foi o problema de saúde bucal mais conhecido pelos entrevistados. A cárie dentária foi representada pela falta de higiene, mas também por fatalidades de cunho biológico que não são possíveis de controlar pelos sujeitos. A presença e os benefícios do flúor na água de beber e no creme dental não foram reconhecidos pela população estudada. Conclui-se que há necessidade de uma integração entre a escola, a família e o dentista, a fim de promover saúde e levar conhecimento para esta população.
Mild Intraocular Pressure Elevation in Mice Reveals Distinct Retinal Ganglion Cell Functional Thresholds and Pressure-Dependent Properties
Authors: Tao Xiaofeng , Sabharwal Jasdeep , Seilheimer Robert L. , Wu Samuel M. , Frankfort Benjamin J.
Published: January 2019

Elevation of intraocular pressure (IOP) causes retinal ganglion cell (RGC) dysfunction and death and is a major risk factor for glaucoma. We used a bead injection technique to increase IOP in mice of both genders by an average of ∼3 mmHg for 2 weeks. This level of IOP elevation was lower than that achieved in other studies, which allowed for the study of subtle IOP effects. We used multielectrode array recordings to determine the cellular responses of RGCs exposed to this mild degree of IOP elevation. We found that RGC photopic receptive field (RF) center size and whole-field RGC firing rates were unaffected by IOP elevation. In contrast, we found that the temporal properties of RGC photopic responses in the RF center were accelerated, particularly in ON sustained cells. We also detected a loss of antagonistic surround in several RGC subtypes. Finally, spontaneous firing rate, interspike interval variance, and contrast sensitivity were altered according to the magnitude of IOP exposure and also displayed an IOP-dependent effect. Together, these results suggest that individual RGC physiologic parameters have unique IOP-related functional thresholds that exist concurrently and change following IOP elevation according to specific patterns. Furthermore, even subtle IOP elevation can impart profound changes in RGC function, which in some cases may occur in an IOP-dependent manner. This system of overlapping functional thresholds likely underlies the complex effects of elevated IOP on the retina.

SIGNIFICANCE STATEMENTRetinal ganglion cells (RGCs) are the obligate output neurons of the retina and are injured by elevated intraocular pressure (IOP) in diseases such as glaucoma. In this study, a subtle elevation of IOP in mice for 2 weeks revealed distinct IOP-related functional thresholds for specific RGC physiologic parameters and sometimes showed an IOP-dependent effect. These data suggest that overlapping IOP-related thresholds and response profiles exist simultaneously in RGCs and throughout the retina. These overlapping thresholds likely explain the range of RGC responses that occur following IOP elevation and highlight the wide capacity of neurons to respond in a diseased state.
Lucilla You Min and Her Embodiment of a Cosmopolitan Fantasy
Authors: Poon Erica Ka-yan
Published: January 2019

Lucilla You Min, who acted in Japanese and Hong Kong coproduced films in the early 1960s, is a valuable case study for postwar East Asian border-crossing star studies. This article conceptualizes the body of the star as a site of constructed meaning, and argues that You Min's embodiment of cosmopolitan fantasy as constructed by the studios she worked for was fraught with corporate and cultural competition in the Cold War era. The first part examines how Japanese cinema's discourses of publicity constructed You Min's embodiment of the imaginary of tōyō—an expression of Japan's desire for a leadership role in mediating between Asia and the West. The second part analyzes how Hong Kong cinema constructed the imaginary of the cosmopolitan, embodied by You Min's seemingly natural adaptability in world travel.
Media Meddlers
Authors: Gopal Sangita
Published: January 2019

This article explores and historicizes the rise of the woman filmmaker in India in the late 1970s and the 1980s in two overlapping domains: a vastly expanded communications infrastructure, including the spread of television, and second wave feminism. It takes as a case study the media maker Sai Paranjpye, whose eclectic career across a range of media—theater, TV, cinema, print—in multiple formats—ad films, documentaries, educational shorts, TV films, full-length features—was fairly typical of the nature of women's media work at this time, as women took whatever work they could find in a rapidly mutating media ecology. The article suggests that these media migrations provide a model of gendered media work that is constitutively intermedial, and thus reorders the aesthetic and narrative protocols of mainstream cinema.
Oocyte-specific deletion of Hdac8 in mice reveals stage-specific effects on fertility
Authors: Singh Vijay Pratap , Yueh Wei-Ting , Gerton Jennifer L , Duncan Francesca E
Published: January 2019

Eighteen histone deacetylases exist in mammals. The class 1 histone deacetylases HDAC1 and HDAC2 are important for oogenesis and fertility in mice, likely via their effects on histones. The reproductive function of HDAC8, another class 1 enzyme, has not been explored. One key target of HDAC8 is the SMC3 subunit of cohesin, an essential complex mediating sister chromatid cohesion and chromosome segregation. In current models, HDAC8 activity is required for SMC3 recycling, but this function should be dispensable in oocytes since cohesion is established during pre-meiotic S phase and maintained until meiotic resumption during ovulation. Whether other oocyte-specific HDAC8-mediated deacetylation events are required for oogenesis and female fertility is unknown. We used two Cre drivers to remove Hdac8 at specific stages of oocyte development to address whether HDAC8 is required for female fertility in mice. When HDAC8 was knocked out in oocytes in primary and later stage follicles (Zp3-Cre), oogenesis and folliculogenesis appeared normal and mice were fertile. However, females were subfertile when HDAC8 was knocked out prior to pre-meiotic S phase and cohesion establishment (Vasa-Cre). This subfertility was independent of chromosome segregation errors during meiosis but rather appeared to be the result of defects in oogenesis that resulted in smaller fully grown oocytes with a reduced ability to resume meiosis. In all cases, we did not observe compensatory changes in HDAC1, HDAC2 and HDAC3 levels. Thus, although oocyte-specific expression of HDAC8 is not essential for mouse oogenesis after meiotic S phase, it contributes to optimal fertility. We infer that oocyte-specific expression of the deacetylase HDAC8 is required early in oogenesis for optimal fertility.

Abstract:

Introduction: The development of nanotechnology increases the risk of occupational and population-level exposure to nanoparticles nowadays. However, scientifically based knowledge relating to the toxicity of heavy metal nanoparticles and potential health damage is insufficient. Aim: Investigation of lung tissue damage induced by titanium dioxide (TiO2) nanorods in subacute intratracheal instillation by morphological, chemical and biochemical methods in rat model. Method: General toxicity (changes of body and organ weights), local acute and chronic cellular toxicity (in alveolar spaces and epithelium, in hilar lymph nodes) and oxidative stress were examined using light and electron microscopy, and biochemical methods (reactive oxygen species, lipid peroxidation, expression of pro-inflammatory cytokines). Results: No dose- and time-dependent alteration was found in the body weight of the treated groups; but the mass and Ti content of lungs increased with dose. Light and electron microscopy of the lung tissue verified the presence of nanoparticles, free in the alveolar space and within phagosomes of macrophages not attached to alveolar epithelium. Chronification of local acute alveolitis was supported by dose-dependent increase of macrophage count in the alveolar region, oedema and thickening of interstitium, and increased expression of certain pro-inflammatory cytokines (interleukin-1a, LIX, L-selectin, vascular endothelial growth factor). Oxidative stress and lipid peroxidation increased substantially in the treated rats’ lungs, and correlation was found between Ti content and lipid peroxidation. Insufficiency of the alveolar epithelial and capillary endothelial barrier was indicated by nanoparticle-laden phagocytes in hilar lymph nodes, suggesting nanoparticles reaching systemic circulation and distant organs, inducing systemic acute inflammation. Conclusion: TiO2 nanoparticles, reaching lower airways, may be etiological factors in the causation or aggravation of pulmonary diseases with acute and chronic airways inflammation and/or progressive fibrosis and obstruction (e.g., chronic obstructive pulmonary disease or asthma). Autophagy and damaged immune response (lymphocytic activity) may have here a role. Orv Hetil. 2019; 160(2): 57–66.

Abstract:

Introduction and aim: Chronic myeloid leukemia is a clonal myeloproliferative disorder characterized by the BCR-ABL gene rearrangement with translocation between chromosomes 9 and 22. The constitutively active BCR-ABL tyrosine kinase inhibitor became the standard frontline therapy. The molecular monitoring is essential. Method: We studied the chronic myeloid leukemia patients at the Clinical Hematology and Bone Marrow Transplant Unit Tg-Mures between 2008 and 2018. Results: We followed 59 patients, median age of 45 years, female : male ratio 1.5 : 1. 80% of the patients were in chronic phase. Sokal score was low in 61%, intermediate 27% and high in 12% of the patients. The median follow-up time was 5 years and 9 months. 59% of the patients reached molecular remission (average time 11 months). The cumulative overall survival was 80% at 5 years and 76% at 10 years. The overall survival according to disease phase was 98%, 85%, 20%; according to Sokal score it was 91%, 66%, 51%. The cumulative progression-free survival was 75% at 5 years and 50% at 10 years. Only 8% of the low risk patients are progressing opposite to 77% of the high risk patients. The cumulative probability to maintain the molecular remission for 5 years is 100%, for 10 years 91% and for 15 years 52%. Conclusion: A rising level of BCR-ABL is an early indication of the loss of response identifying the patients who need close monitoring and therapeutic change. Orv Hetil. 2019; 160(2): 67–72.

Subjectivity in education in the sense of personalization
Authors: Brózda Łukasz
Published: January 2019

Although the inclusion of the subjectivity of the individual seems to be the principle of education today, the term „subjectivity” is understood in different ways, which gives rise to contradictory models of education. It happens so in the case of influential and contrary models of subjectivity, presented by the widely understood antipedagogy and Catholic personalism, which ascribe a strong connotation to it. The analysis of this problem in this article will determine the reflection on the understanding of subjectivity and the characteristics of postmodernity in this context. The aim of this article is to demonstrate that personalism not only protects the subjectivity of the pupil but also does not give up education as it happens in antipedagogy. The role of personalistic education is, in no case, to underestimate the subjectivity of young people but to support the process of preferences and to affirm their proper hierarchy of values, without which their fullness of humanity will not materialize.

W świetle tego dogmatu pełniej i wyraźniej ukazują się fundamentalne prawdy dotyczące życia duchowego.Autor artykułu, analizując prawdę o niepokalanym poczęciu jako dziełu Przenajświętszej Trójcy w osobie Maryi, przedstawia w zarysie, w jaki sposób ta jedna z zasadniczych prawd mariologicznych inspiruje duchowość katolicką. Pod tym kątem rozpatruje więc chrystocentryzm niepokalanego poczęcia, rolę Ducha Świętego, eklezjalny oraz antropologiczno-personalistyczny wymiar tej tajemnicy.

Effect of WRP and FGD gypsum on engineering properties and microstructures of HVBSM
Authors: Han Mincheol , Yi Seong-Tae , Yoon Weonkeun
Published: January 2019

The objective of this study is to investigate the effect of the use of waste refractory powder (WRP) and flue gas desulfurization (FGD) gypsum as an activator on the engineering properties and microstructures of high-volume blast-furnace slag mortar (HVBSM). WRP was used as a magnesium oxide (MgO) source, and FGD gypsum as a calcium sulfate source, to activate blast-furnace slag (BS). The test results indicated that, when BS alone was used for substitution, the flow was lowered compared with that of the control mixture, while the flow increased with substitution with WRP and FGD gypsum. Under the given FGD gypsum contents, the increase in WRP resulted in increased flow. The combined replacement with WRP and FGD gypsum resulted in the enhancement of the compressive strength at the age of 28 d compared to that of the control mixture. It is believed that the activation effect of FGD gypsum on BS in this study was more apparent than that of WRP. For the microstructure observations, HVBSM incorporating WRP exhibited the formation of magnesium hydroxide. In addition, HVBSM with FGD gypsum also showed larger amounts of ettringite and monosulfate hydrate, which allow HVBSM to make denser structures.

ANALISIS POTENSI PROSES CREEP (PEMULURAN) TEHADAP BAHAN BAKAR UJI AKIBAT DISTRIBUSI STRAIN (REGANGAN) DENGAN MENGGUNAKAN PROGRAM FEMAXI. Telah dilakukan analisis potensi proses creep (pemuluran) terhadap bahan bakar uji akibat distribusi strain (regangan) dengan menggunakan program FEMAXI. Tujuan penelitian ini untuk memprediksi kemungkinan terjadinya creep (pemuluran) bahan bakar uji akibat distribusi strain secara melingkar (circumocular), ke arah aksial dan radial pada LHR (linear heat rate) dan waktu operasi tertentu, untuk memberikan informasi terhadap standar kualitas saat produksi dan pengoperasian uji pin di teras reaktor . Hal ini penting dilakukan analisis karena kelongsong sebagai penahan dari tekanan pelepasan produk gas hasil fisi yang dihasilkan saat diiradiasi. Fenomena terjadinya proses creep secara total pada kelongsong pin diasumsikan akibat pengaruh burn-up terhadap pelepasan produk gas fisi akan memberikan tekanan yang dialami kelongsong akibat regangan pada LHR relatif tinggi, laju creep akan bertambah dengan meningkatnya regangan (strain). Hasil analisis mekanikal secara total pin bahan bakar bagian atas (top) dan bagian dalam (inner) pada kondisi operasi tunak menunjukkan terjadi peningkatan creep tergantung pada LHR dan pola operasi di teras reaktor. Untuk kondisi operasi transien menunjukkan peningkatan terjadi creep stabil. Pada kondisi operasi ramp atau operasi perubahan LHR mendadak menunjukkan peningkatan proses creep akibat tekanan regangan berbeda antara pola operasi secara tunak, transien dan ramp pada proses terjadinya creep pada bahan bakar (pelet) dan kelongsong. Hal tersebut akibat produk gas fisi, tetapi hasil akhir perhitungan kondisi pin secara total memberikan informasi bahwa pin hasil produksi masih dinyatakan aman baik ditinjau dari proses termal maupun mekanikal dengan berbagai pola perubahan LHR.Kata kunci: elemen bakar nuklir, pin, kelongsong, pelet
Logarithm Transformed Fr´echet Distribution : Properties and Estimation
Authors: Dey Sanku , Nassar Mazen , Kumar Devendra , Alaboud Fahad
Published: January 2019

In this paper, a new three-parameter distribution called the Alpha Logarithm Transformed Fr\'{e}chet (ALTF) distribution is introduced which offers a more flexible distribution for modeling lifetime data. Various properties of the proposed distribution, including explicit expressions for the quantiles, moments, incomplete moments, conditional moments, moment generating function R\'{e}nyi and $\delta$-entropies, stochastic ordering, stress-strength reliability and order statistics are derived. The new distribution can have decreasing, reversed J-shaped and upside-down bathtub failure rate functions depending on its parameter values. The maximum likelihood method is used to estimate the distribution parameters. A simulation study is conducted to evaluate the performance of the maximum likelihood estimates. Finally, the proposed extended model is applied on real data sets and the results are given which illustrate the superior performance of the ALTF distribution compared to some other well-known distributions.
Influence of accelerated thermal ageing on the performance of alternative solid dielectrics for power transformers
Authors: Ranga C , Chandel A K
Published: January 2019

In the present paper, the influence of accelerated thermal ageing on the performance of alternative solid dielectrics for power transformers, namely thermally upgraded Kraft (TUK), Nomex 910 and Nomex 410 in conjunction with mineral oil, has been investigated. To analyse the properties
of these solid dielectrics with mineral transformer oil, accelerated thermal ageing has been carried out at various temperatures ranging from 100°C to 220°C. Furthermore, in order to compare the operating performance of transformer insulation, several electrical, thermal, physical
and chemical properties of transformer oil, including breakdown voltage, interfacial tension (IFT), water content, absorption coefficient and colour factor, have been determined. Subsequently, the breakdown voltage and tensile strength of different solid dielectrics have been determined. It
has been revealed from the test results that Nomex-impregnated oil samples have shown better thermal performance and oxidation stability than thermally upgraded Kraft-based oil samples. Also, these samples consist of fewer dissolved decay contents and sludge. Therefore, Nomex materials are
suggested as alternative solid dielectrics for power transformers. These solid dielectrics provide a long service run and reduced operating and maintenance costs of transformers. It is envisioned that the present experimental study will be very beneficial for utility managers of transformers.
Fault severity recognition based on self-adaptive particle swarm optimisation using wavelet kernel extreme learning machine
Authors: Zhou Zaichao , Bo Lin , Liu Xiaofeng , Tang Tao , Lv Kai
Published: January 2019

Gear fault levels are an important issue and can show the operating status of gears. In this paper, the extreme learning machine (ELM) learning method is regarded as a basic algorithm for classifying gear fault levels. In order to improve the generalisation of the ELM and obtain a better
classification performance, the wavelet kernel concept was introduced to the ELM and thereby a structure called a wavelet kernel extreme learning machine (WK-ELM) was constructed. In terms of the WK-ELM, because the dilation factor of the wavelet kernel and the number of hidden neurons of
the ELM are important for the classification performance, particle swarm optimisation (PSO) was used to search for the most appropriate values of the solved problem. What is more, PSO was also optimised by a self-adaptive inertia weight that formed a novel structure, that is, self-adaptive
inertia weight particle swarm optimisation (SAPSO). So far, an automatic fault diagnosis system for gear fault levels based on the SAPSO-WK-ELM has been proposed in this paper. Aimed at recognising different gear fault levels at different rotational speeds, ranking mutual information (RMI)
and standardised mutual information (SMI) techniques were applied to select sensitive features for gear fault levels. Compared with other relational algorithms previously used, the results of this study, including simulation and experimental data, have demonstrated that the SAPSO-WK-ELM can
achieve an outstanding classification performance.

Authors: K. Roopa Aravind , Shankar Priya
Published: January 2019

Background: Maternal haemorrhage is the major cause of maternal mortality and morbidity all over the world and more so in developing countries. PPH is the commonest cause of maternal mortality in India. Identification of risk factors, early diagnosis and timely intervention can help in reducing maternal mortality and morbidity significantly. The aim of this study is to analyse the risk factors and causes and study the maternal and perinatal outcomes of PPH in North Karnataka.Methods: It is a retrospective study of 228 patients admitted with the diagnosis of PPH, at KIMS, Hubli during 2016.Results: Average age of the patients was 27 years. Commonest risk factor was PIH, followed by APH and prolonged labour. The commonest cause of PPH was atonicity followed by retained placenta. Majority of the patients recovered successfully with medical management. While 29 patients required Para cervical clamp. Sixteen patients underwent hysterectomy. Commonest complication was anaemia. Total maternal deaths were four; all of them were due to DIC, mostly due to late referrals.Conclusions: Maternal mortality and morbidity due to PPH can be reduced by encouraging regular anti natal visits, timely referral of high-risk patients, training of the health personals and timely intervention. Well stocked blood banks play an important role in management of PPH.

Background: Sepsis is one of the most common cause of neonatal deaths globally more so in low and middle-income countries. The key to management is high degree of clinical suspicion and prompt initiation of empirical antibiotic therapy pending investigations’ results. Knowledge of one’s own NICU flora and antimicrobial susceptibility pattern guides in choosing correct antibiotic therapy to pediatrician. If this data is standard and comparable across different sites, then it also helps in formulating regional and National treatment guidelines. Present study was therefore undertaken to study microbial flora of present NICU and analyze their antimicrobial susceptibility pattern and formulate antimicrobial policy.Methods: Data of blood culture isolates sent from suspected cases of neonatal sepsis received from January 2017 to July 2018 was analysed by “WHONET”.Results: One hundred ninety-three non-repeat isolates were obtained from 992 blood culture samples. Coagulase negative Staphylococcus and K. pneumoniae were the most common isolates. Non albicans Candida were responsible for majority of fungal infection. There was an outbreak of C. pelliculosa for six months. Most of the bacteria were multidrug resistant (MDR). However, except one all other Candida isolates were sensitive to antifungal drugs.Conclusions: WHO guidelines suggest use of penicillin and gentamicin for neonatal sepsis. But in present study, they were not found useful, instead amikacin, netilmicin and piperacillin-tazobactam were found useful and changes were made in antibiotic policy. Authors therefore recommend regular monitoring of antimicrobial susceptibility pattern followed by necessary changes in antibiotic policy for reasonable empirical therapy.

Background: The aim of this research was to compare mindfulness, psychological capital, and self-compassion between students with externalizing problems and normal students in Isfahan city, Iran.
Methods: The statistical population of this case-control study included all the students with externalizing problems and normal students in Isfahan city in the academic year of 2017 - 2018. We used purposive non-probability sampling to collect the samples. In this regard, 100 students with externalizing problems and 100 normal students were selected and asked to complete questionnaires.  The questionnaires used in this study included Mindfulness Skills questionnaires, Self-compassion questionnaire, and PSY CAP questionnaires. The data were analyzed by SPSS23 using analysis of variance.
Results: The results showed that the mindfulness, PSY CAP, and self-compassion were significantly different between the two groups (P-value < 0.0001). The students with externalizing problems had lower scores in mindfulness, PSY CAP, and self-compassion than the normal students.
Conclusion: Students with externalizing behavior problems had lower mental health due to their vulnerable cognitive and psychological processes. Accordingly, mindfulness, PSY CAP, and self-compassion scores were significantly different between the normal students and those with externalizing problems. Considering this difference, we suggest the authorities to pay enough attention to such varieties and conduct appropriate interventions accordingly.

Prognostic factors of poor renal outcomes in renal amyloidosis patients: Systematic review and meta-analysis
Authors: Mwamunyi Mercy Julian , Xiang Huiling , Yao Li-jun
Published: January 2019

Background:Renal involvement by systemic amyloidosis is one of the most common poor outcomes of the disease, usually manifested as nephrotic range proteinuria and can progress to end-stage renal disease (ESRD) with negative effects on the quality of life and survival of the patients. The objective of this meta-analysis was to determine prognostic factors of poor renal outcome in renal amyloidosis patients. The findings of this study may provide a clearer indication of the possibility of worsening state of renal function, which affect monitoring and therapeutic decisions.

Methods:We searched for studies reporting on the renal outcomes in systemic amyloidosis, and cohort studies related to systemic amyloidosis prognosis and/or outcomes.Pooled mean differences, odds ratios and 95% confidence intervals were computed using random-effect approach in Rev Man5.3®. Clinical, laboratory and renal biopsy prognostic factors were tested for heterogeneity and for overall effect. P-value <0.05 was considered statistically significant.

Results: Our search resulted in 7 eligible articles involving 3016 participants in total. Five prospective cohort studies were included. 861 patients had poor renal functional outcomes which included deteriorating estimated glomerular filtration rate, progressing to chronic kidney disease or end-stage renal disease and ESRD-related mortality. Male gender AL (OR 1.58; 95% CI 0.16,15.52, p=0.70) and AA (OR 1.36; 95% CI 0.09, 20.71, p=0.81), proteinuria (OR 1.03; 95% CI 0.40-1.66), serum creatinine (OR1.23; 95%CI 0.65-1.80), eGFR for AA (OR 0.42; 95% CI 0.24-0.72) and eGFR for AL(OR 0.33; 95% CI 0.12-0.91) were poor prognostic factors renal amyloidosis. There were insufficient data to systematically assess age a poor outcome.

Conclusion:The odds of having poor renal prognosis was increased in the male gender, the presence of proteinuria, elevated serum creatinine and decreased eGFR filtration rate. These results highlight the role of aggressive control of modifiable factors like proteinuria, the role of close medical monitoring of patients, that present with fatigue, edema, hypotension, and nephrotic syndrome. These clinical features are strongly associated with renal amyloidosis. Such patients should have a renal biopsy as soon as possible thus to minimize the risk of irreversible kidney damage that adversely affects the renal outcomes.
