Five Year Retrospective Study on Keloid Management

Aim: Keloid morbidity is mostly associated with the psychosocial effects of the cosmetically unsightly scars. The study was carried out to highlight the availability of different treatment modalities and the effectiveness of our treatment strategies. Materials and Methods: A 5 year retrospective study of all patients treated with keloid from March 2012 to February 2017. In this study all patients with keloids attending the plastic surgery clinic at Federal Medical Centre Makurdi and Benue State University Teaching Hospital Makurdi and receiving any form of treatment were included. Results: Thirty one patients were included in our study. Keloids represented 7.2% of benign skin lesions. Keloids were twice more common in females than males. Young patients particularly belonging to the 21 – 30 year old group were mostly affected. Head and neck area was the predominantly affected anatomic site. All patients received some form of treatment and most (90.3%) were treated with the combination of surgery and intralesional triamcinolone acetonide with excellent results. Recurrence was noted in 25.8% of patients. Conclusion: Our study highlights the excellent results of the combination of surgery. With intralesional triamcinolone acetonide, even in patients with difficult keloids like patients from African descent.
Circadian rhythm of expression of core clock genes in the photosensitive pineal organ of catfish, Clarias gariepinus under different photoperiodic regimes

ABSTRACT Effects of different regimes of photoperiod (12L–12D, 16L–8D, 8L–16D, LL and DD) were studied on the circadian rhythm of expression of core clock genes (clock, bmal1, per1, per2, per3, cry1 and cry2) in the photosensitive pineal organ of air-breathing catfish, Clarias gariepinus during summer and winter seasons under both in vivo and in vitro conditions using qPCR. Our findings indicate that all major core clock genes are expressed in the photosensitive pineal organ of C. gariepinus, and exhibit significant circadian rhythm of their expression under both in vivo and in vitro conditions irrespective of photoperiods and seasons. However, photoperiods had season-dependent differential effects on mesor (24 h average), amplitude, and acrophase (peak) of the circadian rhythm of expression of the clock genes under both in vivo and in vitro conditions. Based on these findings, we suggest that the photosensitive pineal organ of the fish possesses internal autonomous clockwork composed of clock genes, and different photoperiods deferentially affect rhythm parameters of the rhythmic expression of the pineal clock genes in a season-dependent manner.
LEARNS: A creative approach to analysing and representing narrative data incorporating photo-elicitation techniques

Background Diversity exists in how storied data gathered in narrative inquiry is analysed and represented, more so when there is a need to combine multiple data collection methods, including photographs. Aim This paper discusses the use of an analytical framework entitled LEARNS developed as part of a PhD study that has potential to fill this gap. Results The step-by-step framework presented in this paper was developed in order to analyse the data collected in this research study and gives understanding and insight into the experience of mothers whose babies are removed at birth. The LEARNS framework provides transparency and credibility; it also negates the need to restrict findings to broad themes via content/thematic analysis. Conclusions LEARNS could offer other researchers a reliable framework to use for future social science research.
Conversation pieces: On recounting new media art mailinglist cultures

Abstract In the field of media art, mailinglists such as nettime, -empyre-, SPECTRE and CRUMB have functioned as important para-institutional formations that have influentially played host to a diverse community of artists, critics, curators, activists and academics since the 1990s. These lists, we suggest, are of particular epistemological and methodological interest for the field of internet history due to their critical and experimental nature. This stems mainly from the cultivation of highly reflexive, at times ambivalent, stance towards the technical, social and aesthetic limits of such networking activity itself. In this sense, they present unique objects of study for exploring what difference computational methods might make for understanding mailinglist cultures over time; what we refer to in this article, drawing on Wolfgang Ernst, as counting and recounting the past. Our aim in this paper is, therefore, to both introduce these lists to the emerging field of internet history and scope out medium-specific methods that take the measure of concepts, discourses, cohorts, and events that have taken place through them over time.

Taxonomic review of the genus Empria Lepeletier & Serville (Hymenoptera, Tenthredinidae) in South Korea: morphological and molecular identification of two new species

The sawfly genus Empria Lepeletier & Serville (Hymenoptera: Tenthredinidae: Allantinae) is reviewed in South Korea and four species are reported as new in the country: Empria lycroi Prous & Park, sp. nov. (also Russia); E. nigroterga Park & Lee, sp. nov. (also Russia); E. wui Wei & Nie (also Japan); and E. zhangi Wei & Yan (also Russia). Tenthredo magnicornis Eversmann, 1864, syn. nov. is treated as a synonym of E. candidata (Fallén, 1808). A key to the six species currently known from South Korea and photographs of the diagnostic characters for each species are presented. In addition, phylogenetic analysis based on one mitochondrial (COI) and two nuclear (NaK, POL2) genes are reported for 20 species of Empria.
Tunable annular acoustic metasurface for transmitted wavefront modulation

We propose a tunable flat acoustic metasurface which consists of fan-shaped tunable annular resonator arrays. The volume of the annular resonators can be adjusted by rotating the outside shell. Compared to existing tunable metasurfaces, it is capable of providing effectively transmitted wavefront modulation in a wide frequency range. We present the details of the acoustic metasurface design, and numerical simulation demonstrates the tunability of the wavefront modulation, and acoustic focusing at different focal spots in varying frequency. The presented tunable annular metasurface broadens our horizons to developing tunable metasurfaces of transmitted wavefront modulations.
Integrated Power Management for Battery-Indifferent Systems With Ultra-Wide Adaptation Down to nW

This article presents a power management unit (PMU) enabling ultra-wide power-performance tradeoff well beyond voltage scaling, and adaptation to the sensed power/energy availability in the harvester and battery. Gap-less power scaling by more than five orders of magnitude and down to nW permits continuous microcontroller unit (MCU) operation regardless of the battery energy availability, thanks to a sub-mm2 on-chip harvester. Such battery-indifferent operation allows to considerably shrink the battery down, as battery discharge no longer has disruptive impact on operation. Battery-indifferent operation is enabled by introducing a purely harvested power mode in the PMU, and widely power-scalable circuits in critical blocks to maintain the power efficiency nearly constant down to nW level. To avoid pessimistic power/timing overdesign, a novel self-biasing comparator and a zero current switching scheme with fast convergence and circuit sharing across power modes are proposed. A 180-nm testchip shows MSP430-like MCU power scaling from sub-mW down to 1.85 nW, with at least 27 $\times $ power dynamic range extension compared to prior art. Self-start-up from 2-nW harvested power is demonstrated, corresponding to a 0.8-mm2 on-chip solar cell with 100-lx illuminance (i.e., equivalent to a very dark overcast day).
Students’ experiences of attending an innovative occupational therapy professional practice placement in a childcare setting

ABSTRACT This study investigated occupational therapy students’ experiences of their alternative fieldwork placement at one childcare center where there was no established occupational therapy service. A semi-structured focus group interview explored four students’ placement experiences. The interview was audio-recorded, transcribed verbatim, and content analyzed. Five categories emerged from the students’: (i) learning opportunities; (ii) skills developed during the placement; (iii) supports and strategies needed for positive and successful learning outcomes; (iv) challenges experienced; and (v) the unique features of the alternative fieldwork placement. The findings contribute to the evidence base of occupational therapy students’ experiences of alternative fieldwork placements as part of their practice education.
Effects of Recreational Activity on Leisure Barriers between Students

Recreation, which means relaxing and pleasant activities that people do voluntarily in their free time, is a concept that provides the physical and psychological renewal of individuals. The study was conducted on a total of 497 students, 248 men participating in recreational sports activities and 249 men who did not participate in any recreational activities. For this purpose “Leisure Constraints Scale”, which was developed by Alexandris and Carroll (1997) and was conducted in the study of the validity and reliability for Turkish Society by Karaküçük and Gürbüz (2007) was used. Statistical analysis of the study was performed by using SPSS 22,0 package program. The normality hypothesis of the data was analyzed by Kolmogorov-Smirnov test. Since all variables showed normal distribution, parametric tests were applied to the independent variables related to the sub-problems and the leisure time scale subscales. Independent t test was used for paired comparisons and Pearson correlation was used for the relationship between variables. Statistical results were evaluated at 95% confidence interval and p <0.05 significance level. As a result, statistically significant differences were found between the students participating in sportive recreation activity in the field and those who did not participate in any recreational activity in terms of leisure time barriers in terms of Individual Psychology, Social Environment, Service and Transportation, Time, Lack of Friends and Lack of Interest. (p<0, 05).
Doing statistics, enacting the nation: The performative powers of categories

Abstract It has been widely acknowledged in debates about nationalism and ethnicity that identity categories used for classifying people along the lines of culture, race, and ethnicity help to enact, that is, bring into being, the collective identities they name. However, we know little about how categories acquire their performative powers. The contribution of this paper is twofold: first, it proposes a conceptual framework based on concepts and insights from science and technology studies for investigating the performative powers of statistical identity categories and possibly also other domains. Second, it demonstrates, through an empirical study of two examples from Estonian and Dutch official population statistics, that statistical identity categories enact more than the groups to which they refer. We argue that they also enact national identities and notions of national belonging of majoritarian groups in the host countries. Therefore, statistical identity categories can be used as analytical lenses to study nationalism and processes of nation‐building.
Modeling Nonlinear Heat Transfer for Pin-on-Disc Sliding System

The objective of this research is to develop a numerical method to characterize heat transfer and wear rates for samples of Vascomax® 300, or Maraging 300, steel. A pin-on-disc experiment was conducted in which samples were exposed to a high-pressure, high-speed, sliding contact environment. This sliding contact generates frictional heating that influences the temperature distribution and wear characteristics of the test samples. A twodimensional nonlinear heat transfer equation is discretized and solved via a second-order explicit finite difference scheme to predict the transient temperature distribution of the pin. This schematic is used to predict the removal of material from the specimens over time based on the temperature profile of the pin. The solutions presented also consider the experimental data and are used to determine characteristics of the contact interface and pin surface associated with the material removal process.
PRINCIPAL BEHAVIORS THAT FOSTER COLLECTIVE EFFICACY AMONG TEACHERS IN RURAL SECONDARY SCHOOLS IN KENTUCKY

OF DISSERTATION PRINCIPAL BEHAVIORS THAT FOSTER COLLECTIVE EFFICACY AMONG TEACHERS IN RURAL SECONDARY SCHOOLS IN KENTUCKY The purpose of this study was to examine principal behaviors, identified by teachers and principals, which foster collective efficacy among teachers. As instructional leaders of a school, principals are expected to lead their schools. Behaviors exhibited by the principal can either help or hinder the success of the school and teachers and students in that school. This study will assist principals, aspiring principals, and instructors of principal preparation programs in knowing what behaviors are necessary to foster collective efficacy in their schools, leading to greater success for that school. Collective efficacy is a shared belief that by working together, “we can make a difference. ” This belief is of great importance in education because through collaboration, educators can influence the lives of children, while positively impacting the success of their school. In a world where testing accountability determines individual and school success, it is imperative to know how to meet those demands. Schools were chosen to participate in this study based on self-reported Collective Efficacy survey results. Principals of grades 9-12 in high-performing rural high schools in Kentucky were surveyed. Following the survey, three schools were chosen as focus sites for this study. The three schools chosen demonstrated high performance on state accountability assessments and had the highest self-efficacy scores on the self-reported survey. Principals and teachers from those schools were interviewed and/or participated in focus groups. This study identifies behaviors of the school principal in building collective efficacy among the teachers in his or her school. These behaviors can lead to a positive school environment and even greater success for students and teachers.
THE EVOLUTION OF THE BEHAVIOUR OF LEARNING APPROACHES OF SECOND YEAR PHYSIOTHERAPY STUDENTS (3-YEAR FOLLOW-UP)

Introduction. Nowadays, teaching-learning process focus on the student. Consequently, to know how students face their learning tasks, could be of increased interest to university lecturers and if such behaviour would change in a short space of time. Objective. To analyse the evolution (3-year follow-up) of the behaviour on the learning approaches employed by Year 2 Physiotherapy students at University of Vigo. Method. Prospective study. The Biggs’ questionnaire on learning approaches was used (Biggs et al., 2001 – original version; Muñoz-San-Roque and Martínez-Felipe, 2012 – Spanish version). The study was carried out in the academic courses 2014-2015, 2015-2016 and 2016-2017 and Year 2 Physiotherapy students participated in it. Total sample was composed of 130 students, 47 students of academic year 2014-2015, 41 of academic year 2015-2016 and 42 of academic year 2016-2017. The average age was 20,60±2,63 years. Results. 53,8% of the participants were women and 46,2% were men. To the total sample and in relation to academic course, there were no statistical differences for “Deep approach” and “Superficial approach”, neither for any of the sub scales (Deep motive, Deep strategy, Superficial motive and Superficial strategy). There was a significant difference by gender for “Superficial approach” and its sub scales (p<0,05), with higher values for male. Also in relation to the gender, 85,71% of the women and 75% of the men had a “Deep approach” contrasting with 10% with “Balanced approach” and 4,29% with “Superficial approach” among the women and 18,33% with “Balanced approach” and 6,67% with “Superficial approach” among the men. Conclusions. A 3-year follow-up on the learning approaches of Year 2 Physiotherapy students assessed by the Bigg’s questionnaire showed no differences among the different academic courses. For this reason, we could think that learning approach among those students who study Physiotherapy Degree is similar. However, there seem to be a difference by gender pointing to higher values for “Superficial approach” and its sub scales among men.
Laparoscopic bariatric surgery-current trends and controversies

Although the origins of bariatric surgery to treat obesity can be traced back to the 1950s with the jejunoileal bypass, which is considered a malabsorptive bariatric procedure, its practice remained in obscurity until two things happened. First, obesity becoming a pandemic disease state with life threatening comorbidities such as diabetes, hypertension, sleep apnea, dyslipidemia and metabolic syndrome, resulting in a higher risk for premature death. Second, the introduction, development, and refinement of minimal access surgical techniques along with newer laparoscopic stapling devices. With the advent of laparoscopy in the 1980s, bariatric surgery began to be performed through minimally invasive techniques. The purpose of this article is to describe the science and evolutionary development of various laparoscopic bariatric surgical techniques and the associated surgical anatomy.
An analysis of the European Union’s conservation funding allocation by habitat and country

Summary Many of Europe’s unique habitats are highly threatened. In order to tackle these threats, the European Union (EU) is annually financing, mainly through its LIFE programme, conservation actions aimed at improving the conservation status of its habitats. We analysed the allocation of the programme’s budget since its inception in 1992 and we found that the number of projects implemented within the EU member states is only weakly related to the number of habitats within them (R2 = 0.39). In some states, fewer than 25% of the habitats have been funded, while in others, more than 75% of the habitats have been funded. There are also disparities in terms of which habitats are being funded; a quarter of them have never received any funding, while others have been targeted by multiple projects. Transnational cooperation between the states is low, further perpetuating the aforementioned disparities. Projects are implemented almost exclusively within the recipient state, often irrespectively of the conservation status of the targeted habitats in other states. We recommend that the EU addresses these disparities by encouraging projects in underfunded states, especially in habitats with unfavourable conservation statuses. Moreover, the EU should encourage transnational cooperation in order to promote effective conservation across the EU and to help underfunded states build their capacity.

It contains a pair of inverted repeat regions of 26,853 bp, each separating a small single copy region of 18,340 bp and a large single copy region of 88,180 bp. Totally, 112 unique genes, including 78 protein coding genes, 30 tRNAs and 4 rRNAs, were identified and annotated in the chloroplast genome. Phylogenetic maximum likelihood analysis indicated that H. cordata Thunb is closest to Piper cenocladu.
A literature review of mobility services: definitions, modelling state-of-the-art, and key considerations for a conceptual modelling framework

ABSTRACT This paper presents a comprehensive literature review focused on the supply side of mobility services, providing relevant insights at the conceptual, operational, and modelling levels. Definitions are first drawn from the Mobility as a Service paradigm due to its predominance in the literature. This is followed by an assessment of the operational features of a range of mobility services, including carsharing, bikesharing, ridehailing, and demand responsive transit. To conclude the review, the state-of-the-art in modelling approaches for mobility services is reported, at different levels of complexity and integration. Three of the most important findings and arguments from this paper suggest that a high degree of generality exists for operational features of mobility services; that it is essential to make a distinction between Mobility as a Service and a mobility service in isolation; along with the argument that human agency should be carefully considered in modelling efforts, both for user agent and driver agent decision-making processes. Finally, key considerations are proposed for the future development of a conceptual framework for modelling the supply side of mobility services, which would have a generic service provider model as its core component.
