Published: January 2020

Zusammenfassung
Mit einem Multi-Punkt-Positionsmesssystem ist es möglich, Positionen und Orientierungen mit sehr hoher Genauigkeit bildbasiert zu messen. Das Messsystem besteht aus einem einfachen Kamerasystem, das um ein diffraktives optisches Element (DOE) erweitert wird. Durch die Multi-Punkt-Methode (MPM) werden Messunsicherheiten von deutlich unter 1/100 Pixel erzielt. Um dies in der Praxis anwenden zu können, ist eine entsprechend hochgenaue Kalibrierung nötig. In diesem Beitrag werden verschiedene Kalibrierverfahren und -funktionen vorgestellt und untersucht. Die Auswertung zeigt, dass sich zur Kalibrierung ein allgemeiner Polynomansatz zusammen mit der Nanomess- und Positioniermaschine NPMM-200 am besten eignet. Es werden Standardabweichungen des Restfehlers von 0,31 µm im Objektraum (etwa 6/1000 Pixel im Bildraum) auf einer Fläche von etwa

Published: January 2020

In this session several critical issues in diverticular disease were considered, including “It is Symptomatic Diverticular Disease or Irritable Bowel Syndrome?”, “What do determine evolution to diverticulitis, bowel habits alteration or inflammation?”, and “Prevention of acute diverticulitis: Is it at all possible?”.
The first talking compared symptoms and laboratory findings between Symptomatic Uncomplicated Diverticular Disease (SUDD) and Irritable Bowel Syndrome (IBS). Although both disease share some symptoms, and although IBS can occur in patients having diverticulosis, SUDD and IBS can be differentiate using a combination of symptoms and laboratory tools.
The second talking debated what are the most important risk factors for the evolution towards acute diverticulitis. Current data seem to exclude a significant role of bowel habits alteration, while inflammation seems to have a stronger role, especially in causing acute diverticulitis recurrence.
The third talking analyzed about the acute diverticulitis prevention. Primary prevention seem to be little better when using mesalazine, while no definite conclusion can be drawn about the use of fiber and rifaximin. About the secondary prevention, no drugs can be currently advised due to lacking of definite results. At the same time, surgery should be advised on case-by-case basis.

Published: January 2020

BACKGROUND AND OBJECTIVES:
Children born extremely preterm (EP) (&lt;26 weeks’ gestation) have lower cognitive scores and an increased rate of cognitive impairment compared with their term-born peers. However, the neuropsychological presentation of these EP individuals in adulthood has not been described. The aim of this study was to examine neuropsychological outcomes in early adulthood after EP birth in the 1995 EPICure cohort and to investigate if the rate of intellectual impairment changed longitudinally.

METHODS:
A total of 127 young adults born EP and 64 term-born controls had a neuropsychological assessment at 19 years of age examining general cognitive abilities (IQ), visuomotor abilities, prospective memory, and aspects of executive functions and language.

RESULTS:
Adults born EP scored significantly lower than term-born controls across all neuropsychological tests with effect sizes (Cohen’s d) of 0.7 to 1.2. Sixty percent of adults born EP had impairment in at least 1 neuropsychological domain; deficits in general cognitive functioning and visuomotor abilities were most frequent. The proportion of EP participants with an intellectual impairment (IQ &lt;70) increased by 6.7% between 11 and 19 years of age (P = .02). Visuospatial functioning in childhood predicted visuomotor functioning at 19 years.

CONCLUSIONS:
Adults born EP continue to perform lower than their term-born peers in general cognitive abilities as well as across a range of neuropsychological functions, indicating that these young adults do not show improvement overtime. The prevalence of intellectual impairment increased from 11 years into adulthood.

Published: January 2020

The aim of this study is to determine winter sports awareness levels of students educated in the field of sports sciences according to the following independent variables: gender, university, class level, experience in winter sports, family membersâ€™ interest in winter sports and monthly family income. The study uses the survey method, and the participants are a total of 562 students attending the School of Physical Education and Sports or the Faculty of Sports Sciences at Kafkas University, KarabÃ¼k University, Kastamonu University and Samsun 19th May University in 2018-2019 academic year. â€œWinter Sports Awareness Scaleâ€, which was developed by Eski (2010), was administered to collect the data for the purposes of the study. This 5-point Likert type scale consists of 35 questions and has three dimensions. However, overall awareness levels of the participants were examined in this study by taking the overall score obtained from the scale rather than the scores for each dimension. SPSS 20 program was used for the analysis of the data. Skewness â€“ Kurtosis values were calculated, and independent sample t-test was used for pair-wise comparisons and One-Way ANOVA and Tukey HSD for multiple comparisons. The results of the analysis revealed medium level awareness for winter sports for all the groups. The comparisons of the mean scores for â€œgenderâ€ and â€œfamily incomeâ€ variables revealed no significant differences while significant differences were found for â€œuniversityâ€, â€œexperience in winter sportsâ€ and â€œfamily membersâ€™ interest in winter sportsâ€ variables.

Gender leadership styles and linguistic practices: The case of Lebanese International University coordinators
Authors: Joudi Nadine Sami 
Published: January 2020

Sociolinguistic research is interested in the way people, including leaders, use language to construct and perform social identities. Given that an increasing number of professional women have to do leadership side by side with men, this case study research, which was conducted at the Lebanese International University, studied gender and leadership styles from a qualitative content analytical perspective. More specifically, it sought to determine male and female leadership styles and to investigate their linguistic practices through the analysis of self-reflections and interviews. The researcher used five male and five female coordinatorsâ€™ self-reflections and transcribed interviews that were collected, analysed and categorised to find out any differences in the leadership style and language use of male and female leaders in the academic settings. The findings showed the influence of the genders in their choice of linguistic expressions indicating the noteworthy dominance of the two prevalent dimensions in leadership styles, namely, transformational and transactional.

Published: January 2020

In this study, it was aimed to determine the opinions of pre-service science teachers about the planned trip to the sugar factory. This study was carried on phenomenology method which is one of the qualitative research methods. The study was carried out with the fourth year students of pre-service science teaching in Erciyes University in 2018-2019 academic year.The data were obtained with semi-structured open-ended questions. The document analysis used in the research was controlled by a science teacher and a science education expert. Codes were generated from the pre-service science teachers' views using content analysis. In the study, it was concluded that out-of-school learning environments have positive effects on science learning and these trips provide permanent and meaningful learning when included in the program. In addition, it was found that out-of-school learning environments concretize knowledge, and discovering new places increases students' desire for science. As students gain experience and make inferences by making observations in out-of-school learning environments, excursions related to courses should be organized.

Effect of Particle Size and Surface Properties on the Sandbed Erosion with Water Flow in a Horizontal Pipe
Authors: Hirpa Mehmet Meric , Arnipally Sumanth Kumar , Bizhani Majid , Kuru Ergun , Gelves Genaro , Al-Rafia Ibrahim 
Published: January 2020

Summary
An experimental study was conducted to investigate the transport of sand particles over the sand bed deposited in a horizontal conduit by using turbulent flow of water. The main objectives were to determine the near-wall turbulence characteristics at the onset of bed erosion (i.e., near-wall velocity profile, Reynolds shear stresses, and axial-turbulent intensity); to determine critical velocity required for particle removal from the bed deposits; and more specifically, to determine how the sand-particle size and surface characteristics would influence the critical velocity required for the onset of bed erosion and the near-wall turbulence characteristics.
A large-scale horizontal flow loop equipped with a nonintrusive laser-based particle-image velocimetry (PIV) system has been used for the experiments. The effect of sand-particle surface characteristics (i.e., wettability) on the critical velocity and the near-wall turbulence characteristics were investigated by using treated and untreated industrial sands of four different mesh sizes (i.e., 20/40, 30/50, 40/70, 100). The PIV technique was used to determine instantaneous local velocity distribution near the stationary sandbed fluid interface under subcritical and critical flow conditions. The near-wall velocity distribution measured directly at the sand bed/fluid interface together with the measured frictional pressure-loss values were then used for the evaluation of the Reynolds shear stresses and axial turbulent intensities acting at the bed/fluid interface.
The results indicated that critical velocity for the onset of particle removal from sand beds increased with the increasing particle size. When sands with special surface treatment were used, it was observed that the critical velocity required for the onset of the bed erosion was significantly lower than that of required for the untreated sands. The degree of reduction in critical velocity varied between 14 and 40% depending on the particle size.
In this study, by conducting experiments under controlled conditions, we provided much-needed fundamental data that can be used for the development of improved solid-transport design criteria and suitable mitigation technologies. In particular, we have shown the proof of concept that the surface-treated sand particles might have great potential for improving the transport efficiency of proppants used for hydraulic-fracturing operations.
A Molecular Dynamics Study of Soaking During Enhanced Oil Recovery in Shale Organic Pores
Authors: Perez Felipe , Devegowda Deepak 
Published: January 2020

Summary
In this work we use molecular dynamics simulations to investigate the interactions during soaking time between an organic solvent (pure ethane) initially in a microfracture and a mixture of hydrocarbons representative of a volatile oil, and other reservoir fluids such as carbon dioxide and water, originally saturating an organic pore network with a predominant pore size of 2.5 nm. We present evidence of the in-situ fractionation in liquid-rich shales and its implications in enhanced oil recovery (EOR) projects. We also discuss the behavior of the larger and heavier molecules in the fluid mixture while the solvent interacts with them. Notably, prior to solvent invasion of the pores and further mixing with the reservoir fluids, the heavier hydrocarbons in the mixture are initially adsorbed onto the pore surface and pore throats surface, partially clogging them. We show that the porous structure of kerogen and the presence of adsorbed molecules of asphaltenes and resins in the pore throats act as a molecular sieve and may be one of the reasons for the fractionation of the reservoir fluids. The differing ability of the solvent to desorb and mix with different hydrocarbon species is another reason for the fractionation occurring during soaking. Our simulations show that the production of reservoir fluids occurs due to a countercurrent diffusive flow from the organic pore network to the microfracture driven by the concentration gradient between the two regions.

Abstract
Background
Although immediate breast reconstruction has been reported to be oncologically safe, no affirmative study comparing the two reconstruction methods exists. We investigated breast cancer recurrence rates in two breast reconstruction types; implant reconstruction and autologous flap reconstruction.
Methods
A retrospective cohort study was performed on propensity score-matched (for age, stage, estrogen receptor status) patients who underwent IBR after mastectomy at Seoul National University Hospital between 2010 - 2014. The main outcomes determined were locoregional recurrence-free interval (LRRFI) and disease-free interval (DFI).
Results
We analyzed 496 patients among 731 patients following propensity score matching (Median age 43, 247 implant reconstruction and 249 flap reconstruction). During median follow-up of 58.2 months, DFI was not different between the two groups at each tumor stage. However, flap reconstruction showed inferior DFI compared to implant reconstruction in patients with high histologic grade (p=0.012), and with high Ki-67 (p=0.028). Flap reconstruction was related to short DFI in multivariate analysis in aggressive tumor subsets. Short DFI after flap reconstruction in aggressive tumor cell phenotype was most evident in hormone positive/Her-2 negative cancer (p=0.008). LRRFI, on the other hand, did not show difference according to reconstruction method regardless of tumor cell aggressiveness.
Conclusion
Although there is no difference in cancer recurrence according to reconstruction method in general, flap-based reconstruction showed higher systemic recurrence associated with histologically aggressive tumors.

Published: January 2020

Abstract
Background: Simple bone cysts (SBCs) are common benign lytic bone lesions in children. This study focused on exploring a clinical treatment method, minimally invasive intramedullary decompression and drainage with elastic stable intramedullary nailing (ESIN) combined with intralesional injections of steroids, and evaluated its effectiveness, complications and morbidity through functional and radiographic outcomes. Methods: The postoperative recovery of 18 children who suffered from SBCs of humerus was evaluated (mean follow-up, 40 months) from January 2009 to December 2016. These patients (11 males, 7 females; 8 in the left, 10 in the right; mean age, 10.9 years old) were treated with minimally invasive intramedullary decompression and drainage with ESIN combined with intralesional injections of steroids. The diagnosis was based on not only pre-operative typical medical images (X-rays/CT/MRI) but also surgical findings and pathological diagnosis. Radiological and functional outcomes were evaluated according to Capanna and Musculoskeletal Tumor Society (MSTS) score. The interclass differences were analyzed by t-test. Results: According to Capanna and MSTS criteria, after treatment, 14 patients made full recoveries which was presented by all the cysts filled with bone tissue, and 4 patients made partially recoveries, which were presented by cystic spaces partially filled with low density bone. All the cysts responded to treatment method, and there was no cyst recurrence. All except 2 patients had good functional results. One of the two patients had irritation of the end of the nail and one patient had a valgus deformity. Conclusions: Treatment for SBCs of humerus by minimally invasive intramedullary decompression and drainage with ESIN combined with intralesional injections of steroids is safe, effective and convenient. The clinical effect is satisfactory and worth popularizing.

Published: January 2020

Abstract
Background: The development of tumor cells inside the lymphatics or blood vessels is known as lymphovascular invasion (LVI). The correlation between LVI, lymph node metastasis (LNM), and the diagnosis of superficial esophageal carcinoma (SEC) remains unclear. Methods: We searched Embase, PubMed, Web of Science, and Cochrane Library databases for prospective articles to better understand the relationship between LVI, LNM, and SEC diagnosis. Results: We included 28 articles containing data for 5041 patients (range: 29-498) in our meta-analysis. The hazard ratio between LVI and overall survival (OS) was 1.62 with 95% confidence interval (CI) (1.17-2.26; p = 0.004) and the odds ratio between LVI and LNM was 5.7 with 95% CI (4.43-7.33; p < 0.0001). LVI in patients diagnosed with SEC results in a poor OS rate and a higher rate of LNM. Conclusions: The results indicate that LVI plays a dominant role in the prognosis of LNM in SEC and in the prognostic prediction for SEC.Keywords: Lymphovascular invasion; lymph node metastasis; prognosis; superficial esophageal carcinoma
