Comparison of perioperative outcomes of single-port laparoscopy, three-port laparoscopy and conventional laparotomy in removing giant ovarian cysts larger than 15 cm
Authors: Wang Xiaoying , Li Yan 
Published: April 2021

Abstract
Background
Although conventional laparoscopy has gradually accepted as a surgical treatment for ovarian cancer, reducing the port numbers of laparoscopy still has great challenge for larger ovarian tumors. Thus, this study aims to explore the surgical outcomes of single-port laparoscopy for removing giant ovarian cysts (≥ 15 cm) and compare with laparotomy and three-port laparoscopy.

Methods
This study enrolled 95 patients with giant ovarian cysts (> 15 cm) who underwent single-port laparoscopy, three-port laparoscopy or laparotomy. Their medical records, perioperative surgical outcomes, and postoperative pain score and complications were analyzed and compared retrospectively.

Results
Single-port laparoscopy showed better perioperative outcomes and less postoperative pain than three-port laparoscopy and laparotomy. The time between post-surgery and getting out of bed in single-port laparoscopy was significant shorter than that in the laparotomy and three-port laparoscopy (17.53 ± 7.26 vs 29.40 ± 9.57 vs 24.56 ± 7.76, P < 0.01). The length of hospital stay in single-port laparoscopy was significantly shorter than that in other two groups (4.06 ± 0.5 vs 5.46 ± 1.63 vs 4.81 ± 0.83, P < 0.001). In addition, single-port laparoscopy had the lowest postoperative pain scores than in the laparotomy and three-port laparoscopy. There were no significant differences of total hospital cost, postoperative complications and time until gas passing among the three surgical groups. Importantly, in the removal of giant ovarian cysts, the proportion of cyst rupture in single-port laparoscopy was far lower than that in three-port laparoscopy (3.0 vs 22.2%).

Conclusions
For giant ovarian cysts, single-port laparoscopy is still a safe and efficient technique with the advantages of short operation time, less estimated blood loss, short hospital stay, lower spillage rate, and less postoperative pain.
Copeptin, pro-atrial natriuretic peptide and pro-adrenomedullin as markers of hypoxic stress in patients with obstructive sleep apnea—a prospective intervention study
Authors: Karakioulaki Meropi , Grendelmeier Peter , Strobel Werner , Schmid Thomas , Jahn Kathleen , Grize Leticia , Tamm Michael , Stolz Daiana 
Published: April 2021

AbstractStudy ObjectivesObstructive sleep apnea (OSA) might lead to oxidative stress, inflammation and elevated circulating copeptin, proANP and proADM levels. We aimed to evaluate whether the levels of these prohormones are higher in patients with OSA and whether they might change under continuous positive airway pressure (CPAP) therapy, serving as potential proxies for the diagnosis and therapy-response in OSA.MethodsA total of 310 patients with suspicion of OSA were recruited. Screening for OSA was performed using overnight pulse oximetry followed by polygraphy and a venous puncture in the morning. All patients diagnosed with OSA underwent CPAP adaptation. A venous puncture was conducted in the night before CPAP and in the following morning. At 1 and 6 months of treatment, polygraphy was performed, followed by a venous puncture in the morning. In the acquired blood, copeptin, proANP and proADM levels were measured.ResultsWe analyzed 232 patients with OSA and 30 patients without OSA. Our results indicated that only copeptin levels differed significantly among patients with and without OSA at baseline. In OSA patients, the levels of proADM significantly changed after 1 and 6 months on CPAP therapy, when compared to baseline (p < 0.001 and p = 0.020). Additionally, proANP levels significantly decreased after 12 h on CPAP therapy, as compared to baseline levels (p < 0.001).ConclusionsCopeptin is significantly associated with the presence of OSA. ProANP levels might serve as a potential proxy for the acute response to non-invasive ventilation (12 h), while proADM reflects the long-term response (1 and 6 months).
Research on gray correlation analysis and situation prediction of network information security
Authors: Ye Chengqiong , Shi Wenyu , Zhang Rui 
Published: April 2021

AbstractIn order to further improve the accuracy and efficiency of network information security situation prediction, this study used the dynamic equal-dimensional method based on gray correlation analysis to improve the GM (1, N) model and carried out an experiment on the designed network security situation prediction (NSSP) model in a simulated network environment. It was found that the predicted result of the improved GM (1, N) model was closer to the actual value. Taking the 11th hour as an example, the predicted value of the improved GM (1, N) model was 28.1524, which was only 0.8983 larger than the actual value; compared with neural network and Markov models, the error of the improved GM (1, N) model was smaller: the average error was only 2.3811, which was 67.88% and 70.31% smaller than the other two models. The improved GM (1, N) model had a time complexity that was 49.99% and 39.53% lower than neural network and Markov models; thus, it had high computational efficiency. The experimental results verify the effectiveness of the improved GM (1, N) model in solving the NSSP problem. The improved GM (1, N) model can be further promoted and applied in practice and deployed in the network of schools and enterprises to achieve network information security.

Authors: Viergever Koen , Kraak Jeroen T. , Bruinewoud Els. M. , Ket Johannes C. F. , Kramer Sophia E. , Merkus Paul 
Published: April 2021

Abstract
Background
Patient-reported outcome measures (PROMs) are valuable tools in assessing the quality of health care from a patient perspective and are increasingly used by otologists. However, selecting the right questionnaire has proven to be a difficult and time-consuming task. To facilitate this process, we will provide a comprehensive overview of existing questionnaires.

Methods
A systematic literature search has been conducted on August 26, 2019, using the EMBASE and PubMed medical databases. 13,345 unique records were extracted. Questionnaires addressing any otologic complaint (tinnitus, hearing loss, earache, otorrhoea, and ear-related pressure sensation, vertigo, itch, or dysgeusia) were identified. All questionnaires were evaluated for eligibility by two independent researchers. Inclusion criteria were adult population, closed-ended questions, English language of the questionnaire, and the availability of the original article describing the development of the instrument or a validation paper describing the validation process written in English.

Objective
Create a comprehensive overview of all validated closed-ended otology questionnaires for adults and demonstrate their basic characteristics.

Main outcome measure
The number of questionnaires in English literature for the adult population, subdivided per symptom and target population.

Results
A total of 155 unique questionnaires were selected: 33 tinnitus questionnaires, 23 vertigo questionnaires, 84 hearing loss questionnaires, and 15 multiple complaint questionnaires. A protocol for further questionnaire comparison is presented.

Discussion
Two separate sequential searches were needed to identify unique questionnaires and to identify their development/validation paper. Although many ear diseases create multiple symptoms, the majority of the questionnaires were symptom specific.

Conclusion
Many questionnaires concerning ear-related symptoms exist and predominantly concern hearing loss, vertigo, or tinnitus. Only a few questionnaires cover the multiple complaints that ear diseases can create. The presented overview is the most comprehensive overview of otology questionnaires in literature to date. It will serve as a basis for questionnaire selection by professionals and could serve as a protocol for questionnaire selection in other fields.

Analysing students’ environmental awareness profile using strategic environmental assessment
Authors: Khoiri Ahmad , Sunarno Widha , Sajidan Sajidan , Sukarmin Sukarmin 
Published: April 2021

Background: Environmental awareness (EA) is a part of character education ignored by most students. This indifference tends to affect other students’ by not only in protecting and preserving the current environment but also in preventing and repairing the damage that occurs in the environment. This research analyses students' EA profile, based on the findings of LISREL 8.8 Confirmatory Factor Analysis. Methods: Research subjects included 131 students from Senior High School State 1 Selomerto Wonosobo, Central Java Province, Indonesia. Based on the Slovin formula, the number of samples is representative of the total population (N: 185; error tolerance: 0.05). Data were collected through non-test questionnaires and observation of Strategic Environmental Awareness (SEA). Quantitative descriptive data analysis on EA indicators (Care, Curiosity, Critical, Dependability, Responsibility, and Local Wisdom). Results: The EA profile of high school students was categorised sufficiently. This revealed the following results: a) the SEA instrument is effective in identifying students’ awareness about current environmental issues and meets model fit criteria (P-value 0.25>0.05; RMSEA 0.095; NFI 0.67); b) the SEA instrument is valid and reliable in accurately determining students’ EA profile; c) although the Responsibility profile was significant (t >1.96), other variables did not meet this significance criteria (EA 1a: ‘Care towards environmental damage’ under the Care profile; EA 3b: ‘Contributing towards preserving the environment’ under the Critical profile; and EA 6b: ‘Aware of local potentials’ under the Local Wisdom profile); d) evaluation of the expected changes in SEA is modified through an ethnoscience approach and the socioscientific issues strategy. Conclusions: Students’ lack of awareness of the environment and understanding of their regional potential fails to contribute towards creating a sustainable environment. Profile analysis in exploring attitudes, values, and ethics towards the environment are important, as it helps recognize students’ behaviour.

This study examined occupational-related stress among university faculty staff and its implications on goal attainment of universities in Kwara State, Nigeria. The research design was a descriptive research of a cross-sectional survey. Multi-stage sampling technique was used for the selection of 458 faculty staff. Data were collected with the use of 57-item questionnaire. Data collected were analyzed with relevant statistics like percentage, mean, standard deviation, t-test statistics and analysis of variance (ANOVA). Findings revealed that the level of stress among faculty staff was high (3.25), while stress level differs based on gender (p<.05), age (p<.01), marital status (p<.01), work experience (p<.05) and ownership of workplace (p<.05). The prominent risk associated with occupational-related stress were the organizational-related (cluster mean 3.26) and role-related (CM 3.26) factors. Finding further indicated that the social support (CM 3.00) and individual-focused (CM 2.91) coping strategies were moderately adopted for managing occupational-related stress among university faculty, while the organizational support coping strategy was utilized to a low extent (CM 2.47). The findings implicate the attainment of university goals because of the negative effect high-stress level will have on the physiological and behavioural state of faculty staff adding to destructive work and health anomalies.

Kerr-lens mode-locked Yb:LuAG ceramic thin-disk laser
Authors: Kitajima Shotaro , Shirakawa Akira , Yagi Hideki , Yanagitani Takagimi 
Published: April 2021

A Kerr-lens mode-locked (KLM) thin-disk laser with Yb:LuAG ceramic was demonstrated. Yb:LuAG ceramic is an attractive material for high-power lasers due to its high thermal conductivity and large emission cross section. The highest output power of 17 W with a pulse duration of 130 fs was achieved. Moreover, the pulse duration of 88 fs was also obtained with a high-Q factor cavity. To the best of our knowledge, this is the first demonstration of a KLM thin-disk laser based on Yb:LuAG, including both ceramic and single crystal. The results show the usefulness of ceramic thin disks for high-power ultrashort pulse laser sources.
Responsible product design to mitigate excessive gambling: A scoping review and z-curve analysis of replicability
Authors: McAuliffe William H. B. , Edson Timothy C. , Louderback Eric R. , LaRaja Alexander , LaPlante Debi A. 
Published: April 2021

Objectives
Systematic mapping of evaluations of tools and interventions that are intended to mitigate risks for gambling harm.

Design
Scoping Review and z-curve analysis (which estimates the average replicability of a body of literature).

Search strategy
We searched 7 databases. We also examined reference lists of included studies, as well as papers that cited included studies. Included studies described a quantitative empirical assessment of a game-based (i.e., intrinsic to a specific gambling product) structural feature, user-directed tool, or regulatory initiative to promote responsible gambling. At least two research assistants independently performed screening and extracted study characteristics (e.g., study design and sample size). One author extracted statistics for the z-curve analysis.

Results
86 studies met inclusion criteria. No tools or interventions had unambiguous evidence of efficacy, but some show promise, such as within-session breaks in play. Pre-registration of research hypotheses, methods, and analytic plans was absent until 2019, reflecting a recent embracement of open science practices. Published studies also inconsistently reported effect sizes and power analyses. The results of z-curve provide some evidence of publication bias, and suggest that the replicability of the responsible product design literature is uncertain but could be low.

Conclusion
Greater transparency and precision are paramount to improving the evidence base for responsible product design to mitigate gambling-related harm.
A retórica populista do jornal Extra
Authors: Reis Rodrigo Nascimento , Da Silva Marco Antonio Roxo 
Published: April 2021

O Extra, com sede no Rio de Janeiro e fundado em 1998, é um dos jornais populares reconhecidos no Brasil pela linguagem simples, preço acessível e proximidade com a realidade do público. Nessa direção, o artigo busca verificar como ocorreu a atuação do veículo durante a Copa do Mundo de 2014. Deslocamos, portanto, o conceito de populismo do campo político para estudá-lo apenas na sua forma comunicativa e empreendemos uma análise para entender como o impresso fala em nome do povo e onde estaria o apelo emocional. A coleta, por meio da adjetivação do veículo aos jogadores, partidas, seleções e outros tópicos, atua como chave explicativa para identificar uma discursividade populista. Nesse sentido, encontramos no veículo um apelo retórico, já bastante conhecido nas disputas políticas, que no caso da Copa foi frisado pela linguagem carregada, uso de bordões futebolísticos, narrativas de cunho apelativo e dramático envolvendo o contexto das partidas.

Kant on Moral Respect
Authors: Berg Anastasia 
Published: April 2021

Abstract
Kant’s account of the feeling of moral respect has notoriously puzzled interpreters: on the one hand, moral action is supposed to be autonomous and, in particular, free of the mediation of any feeling on the other hand, the subject’s grasp of the law somehow involves the feeling of moral respect. I argue that moral respect for Kant is not, pace both the ‘intellectualists’ and ‘affectivists,’ an effect of the determination of the will by the law – whether it be a mere effect or the motivating cause of action – but is instead identical to it. Drawing on Kant’s general account of feeling as the awareness of how representations and their objects harm or benefit our own powers, I argue that the identity between moral respect and the determination to action contains two elements. Moral respect is, first, a form of practical self-consciousness which constitutes the subject’s recognition of the moral law and thus of herself as intrinsically bound by it, i. e., as a moral agent. Second, respect is a capacity for receptive awareness of particular features of our environment as well as other persons insofar as they benefit and harm us as moral agents. Thereby moral respect affords us awareness in concreto of particular, morally-conditioned ends. In this way moral respect provides the key for a Kantian account of genuinely free practical receptivity.
Structural assessment of St. Charles hyperbolic paraboloid roof
Authors: Schultz Joshua A. , Henriksson Viktoria 
Published: April 2021

Abstract
At the time of completion in 1961, the roof of St. Charles Church became the largest unbalanced hyperbolic paraboloid structure in the United States and the only shell structure in Spokane, WA. Situated on an 8-acre site on the north side of the city, St. Charles is a modernist structure designed through partnership of Funk, Molander & Johnson engineers, architect William C. James and in consultation with Professor T.Y. Lin of the Structural Engineering Laboratory at the University of California, Berkeley. This asymmetric structure spans over 33.5 m (110 ft) and utilizes folded edge beams that taper from 1067 mm (42 in) at the base to a 76.2 mm (3 in) thickness at the topmost edge using regular strength reinforcing steel and concrete load carrying components. The novelty of the pre-stressed shell structure serves both architectural and structural design criteria by delivering a large, uninterrupted interior sanctuary space in materially and economically efficient manner. This structural assessment summarizes the roof’s historic design and construction according to the original construction documents, newspaper reports and historic photographs. The FEA is completed using UBC 1955 design loads and ACI 334 Concrete Shell Structures provisions.
Folklinguistic perceptions of Global Englishes among German learners of English
Authors: Meer Philipp , Hartmann Johanna , Rumlich Dominik 
Published: April 2021

Abstract
While recent research on English language teaching (ELT) in Germany has called for a more comprehensive representation of the diversity of English worldwide, learners’ perceptions of Global Englishes are currently underresearched despite their importance for a successful implementation of this change in ELT. The present paper analyzes 166 German secondary school students’ perceptions of Global Englishes, underlying cultural associations, and stereotypes. To this end, a perceptual dialect identification task, keyword association, and direct open questions were combined in a folklinguistic study. The results show that the informants consider British and American English as general standards and primarily associate English-speaking countries with Inner Circle varieties: British, American, and Australian English. British English is regarded as the default school reference norm, while American English is associated with dynamism and casualness. Furthermore, the students identify Indian and African English(es) as important Global Englishes. Their perceptions of these varieties are, however, less positive and seem to be influenced by cultural stereotypes, which might prompt them to perceive these varieties as funny or unintelligent. We suggest that learners’ existing knowledge of Global Englishes and explicit metalinguistic discussions of variation can be used as starting points to counteract such stereotypes.
